ITEM 1. BUSINESS

INTRODUCTION

     Leap Wireless International, Inc., is a wireless communications carrier
that deploys, owns, operates and participates in wireless networks in domestic
and international markets with strong growth potential. Through its operating
companies, Leap has launched all-digital wireless service in the United States,
Mexico and Chile. Leap is dedicated to bringing the benefits of reliable,
cost-effective and high-quality wireless communications services to domestic and
growth markets.

     Upon completion of its pending asset acquisitions, Leap and its operating
companies will own wireless communications licenses covering approximately 138
million potential customers or "POPs" in the United States, Mexico and Chile.
Leap's equity share of this pool of potential customers will be approximately 67
million potential customers, although this share may decrease in the future as
Leap's operating companies sell additional equity.

     Leap's domestic strategy is to offer consumers a simple and affordable
wireless service plan that allows them to make all of the local calls they want
for a low, flat monthly rate. The service, marketed under the name
"Cricket(SM)," is targeted at the mass consumer market. Leap's Cricket(SM)
concept was introduced in Chattanooga, Tennessee in March 1999 using the
existing infrastructure of Chase Telecommunications, Inc., a company that Leap
has agreed to acquire. The service was launched under an agreement that requires
the management of Chase Telecommunications to control the business until Leap's
pending acquisition of Chase Telecommunications receives all necessary
governmental approvals and is completed. Leap expects that Chase
Telecommunications will introduce the Cricket(SM) service concept in Nashville,
Tennessee in early 2000. Since September 1998, Leap has acquired or agreed to
acquire wireless communications licenses covering approximately 24 million
potential customers in the United States (based on 1998 data). Leap is also
considering additional domestic license acquisitions. Over the next several
years, Leap expects to launch Cricket(SM) service in numerous markets in which
it has acquired licenses or has agreed to acquire licenses.

     In the international arena, Leap plans to focus its efforts in growth
markets where Leap's ability to provide value added services will increase the
likelihood of launching successful wireless ventures. When making new
investments in growth markets, Leap generally expects to seek investment
partners that provide familiarity with local markets, financial and technical
resources, an ability to facilitate development in a particular market, or other
attributes that can contribute to a successful network-building enterprise. Leap
expects to be actively involved in each joint venture operation in which it
holds a significant position.

     In Mexico, Leap's operating company, PEGASO Telecomunicaciones, S.A. de C.
V., is deploying the first 100% digital wireless communications network in
Mexico. PEGASO holds licenses to provide nationwide wireless service in Mexico
and plans to build one of the largest wireless communications networks in Latin

                                        1
<PAGE>   3

America. PEGASO has already launched operations in three of Mexico's four
largest cities: Tijuana, Guadalajara and Monterrey. The company expects to
launch service in Mexico City, the country's largest city, near the end of 1999.
After that launch, PEGASO plans to roll-out its network in additional
metropolitan areas as well as tourist destinations and major border cities.

     Leap's operating company in Chile, which is being renamed SMARTCOM PCS and
is referred to as SMARTCOM in the remainder of this report, operates a
nationwide wireless system in Chile. SMARTCOM launched its system in Chile in
September 1998. Leap purchased the 50% of SMARTCOM that it did not already own
from its former joint venture partner in April 1999. Over the last several
months, Leap has strengthened SMARTCOM's management team and expanded SMARTCOM's
marketing and customer acquisition efforts.

     At the end of Leap's first fiscal year, its operating companies had almost
60,000 domestic and international subscribers -- 42,000 in Chile, 12,400 in the
United States and 5,500 in Mexico, primarily from its first market in Tijuana.
Leap's proportionate share of the total subscriber base was approximately
44,500, based on Leap's 100% ownership of SMARTCOM, 28.6% ownership of PEGASO,
and its 7.2% stake in Chase Telecommunications, Inc.

     Leap, a Delaware corporation, was formed in June 1998 as a subsidiary of
QUALCOMM Incorporated, a provider of digital wireless communications products,
technologies and services. In September 1998, QUALCOMM contributed several of
its wireless communications businesses and ventures to Leap and distributed all
of Leap's outstanding shares of common stock to QUALCOMM's stockholders as a
taxable dividend.

INDUSTRY BACKGROUND

     Domestic and international telecommunications markets are expanding
rapidly. Developing countries are seeking to increase their number of telephone
lines as a percentage of their population (known as teledensity) and to increase
competition among carriers. In addition, increased demand, decreased government
regulation, and new spectrum auctions have created domestic and international
opportunities for new providers to capture market share. Leap believes that
wireless is the cheapest and fastest way to increase teledensity and that it
possesses the expertise to oversee and manage the entry of new wireless
operating companies into today's competitive markets.

     Wireless communications service is currently available using either analog
or digital technology. Although analog technology is more widely deployed than
digital technology, its use is growing more slowly and analog technology has
significant limitations. Digital wireless communications systems overcome the
capacity constraints of analog systems by converting voice or data signals into
a stream of digits that is compressed before transmission, enabling a single
radio channel to carry multiple simultaneous signal transmissions. This
increased capacity, along with enhancements in digital protocols, allow
digitally based systems to offer new and advanced services including greater
call privacy and security, fraud protection, consistently higher voice quality,
and integrated voice and paging. Digital systems also provide enhanced wireless
data transmission allowing for higher speed and more reliable wireless e-mail
and internet use.

     The primary digital technologies available for wireless fixed and mobile
applications are Code Division Multiple Access, known as CDMA, and Time Division
Multiple Access, known as TDMA. TDMA includes several variants, including
Digital Advanced Mobile Phone System also known as D-AMPS which is deployed
primarily in North and South America, and Global System for Mobile
Communication, known as GSM, which is widely deployed in Europe, where the
technology was developed, and in many other markets around the world.

     Leap is currently committed to owning and participating in networks that
utilize CDMA technology. Leap believes that CDMA technology is the best platform
to meet current network requirements as well as the best platform for third
generation or "3G" based services. CDMA technology currently provides from three
to five times the capacity of other digital technologies, enabling service
providers to support more subscribers and greater volumes of wireless traffic
within a given amount of radio frequency spectrum. As a result, CDMA

                                        2
<PAGE>   4

networks can provide high capacity using less spectrum and fewer cell site
towers. This reduces both initial capital expenditures as well as ongoing
operational and maintenance costs. CDMA is also the only wireless technology
that effectively supports both fixed voice and data services along with full
mobility services from the same platform, providing companies that utilize CDMA
technology flexibility in structuring their service offerings and in responding
to changing market demands. In addition, "1XRTT," the first phase of third
generation CDMA technology, is expected to provide more than double the voice
capacity of existing CDMA systems and to deliver high speed data to users.

CORPORATE STRATEGY

     Leap's strategy is to provide management and project expertise to, and to
selectively invest in and manage, joint ventures and other collaborative efforts
to provide wireless communications services in markets with significant growth
potential. Leap believes its wireless communications experience and the
technical and commercial expertise of Leap and its contractors will benefit Leap
and the entities in which it invests. Leap also expects to expand its expertise
through the experience gained on its current and future ventures to become a
sought after and more valuable participant in future joint ventures.

     Leap intends to focus its efforts on its current projects and on a limited
number of additional opportunities that become available in the future, taking
into account its management and capital resources. In the international arena,
Leap plans to focus its efforts in growth markets where Leap's ability to
provide value added services will increase the likelihood of launching
successful wireless ventures.

     When making new international investments, Leap generally expects to seek
investment partners that provide familiarity with local markets, financial and
technical resources, an ability to facilitate development in a particular
market, or other attributes that can contribute to a successful network-building
enterprise. Leap seeks to ensure that its strategic alliances will enable Leap
to better prepare and equip its operating companies for successful development.

     Although Leap may not hold a majority ownership in many of the joint
ventures in which it elects to participate due to a variety of reasons, Leap
expects to exercise, to varying degrees, significant management influence and
oversight over the businesses in which it invests. Leap believes its experience
and business relationships enable it to add value to its operating companies and
increase their performance and likelihood of success.

LEAP OPERATING COMPANIES

     Leap's businesses and operating companies are described below.

  CRICKET

     General. Leap's domestic strategy is to offer consumers a simple and
affordable wireless service plan that allows them to make all of the local calls
they want for a low, flat monthly rate. The service, targeted at the mass
consumer market, is advertised as the "around-town phone(SM)" and "comfortable
wireless(SM)" and is marketed under the name "Cricket(SM)." This strategy is
different from the existing model used by most current wireless operators in the
United States, who generally offer consumers a "bundle" or maximum amount of
minutes of use for a fixed price with additional charges imposed for minutes of
use above the set maximum.

     The Cricket(SM) service concept was introduced in Chattanooga, Tennessee in
March 1999 using the existing infrastructure of Chase Telecommunications, Inc.,
a company that Leap has agreed to acquire. The service was launched under an
agreement that requires the management of Chase Telecommunications to control
the business until Leap's proposed acquisition of Chase Telecommunications
receives all necessary governmental approvals and is completed. Leap currently
owns 7.2% of Chase Telecommunications Holdings, Inc., the parent corporation to
Chase Telecommunications, Inc.

     Since September 1998, Leap has acquired or agreed to acquire wireless
communication licenses covering approximately 24 million potential customers in
the United States. Leap is also considering additional domestic spectrum
acquisitions. Over the next several years, Leap expects to launch Cricket(SM)
service in
                                        3
<PAGE>   5

numerous markets in which it has acquired licenses or has agreed to acquire
licenses. These markets include cities such as Albuquerque, Boise, Charlotte,
Dayton, Greensboro, Knoxville, Little Rock, Memphis, Nashville, Salt Lake City,
Spokane, Tucson, Tulsa and Wichita.

     Market Opportunity. Wireless penetration was approximately 25% in the
United States at the end of 1998. Wireless companies have generally focused
their U.S. marketing on highly mobile customers, including business users, who
are likely to generate the highest revenues. Customers are typically offered
multiple service plans with prices based on the customer's minutes of use during
the billing period. The numerous plans offered by wireless companies have tended
to confuse many potential customers. Market research indicates that many people
are interested in a wireless product but are concerned about the cost and
complexity of wireless pricing plans.

     The Cricket service model focuses on the mass consumer market rather than
on highly mobile business customers. The Cricket model does not provide roaming
outside of the local service area and thus is not likely to be selected by
highly mobile customers. Cricket's fixed price, unlimited local service,
however, is designed to appeal to the mass consumer market in which customers
are most likely to use their wireless phone in the areas where they live and
work and have a limited need to use their wireless phones outside of their local
calling area. Cricket's fixed price service plan is also designed to overcome
consumer concerns about pricing.

     Capital Requirements and Projected Investments. Leap will require
substantial capital to develop and operate wireless networks in the numerous
markets in which it plans to operate Cricket service in the United States. The
amount of financing that Leap will require for these efforts will vary depending
on the number of these networks that are developed (including any markets
covered by future Leap spectrum acquisitions) and the speed at which Leap
constructs and launches these networks. In fiscal 2000, Leap expects to finance
these development and operation costs largely through vendor financing and
amounts available under its credit agreement with QUALCOMM. Leap expects,
however, that it will also need to raise additional capital to fund its planned
roll-out of domestic networks and acquisitions of spectrum in fiscal 2000. As a
result, Leap is currently exploring debt and equity financing alternatives.

     Regulatory Environment. Leap's business plan anticipates and depends on its
acquisition and operation of C-Block and F-Block spectrum in the United States.
Although C-Block and F-Block licenses are generally more available and are less
expensive to obtain than licenses in other spectrum blocks, a licensee may hold
these licenses only if it qualifies as a "designated entity" under FCC rules.

     In July 1999, the FCC issued an opinion and order that found that Leap was
qualified to acquire C-Block and F-Block spectrum. The order also approved
Leap's acquisition of the 36 C-Block licenses that Leap won in the FCC's 1999
spectrum reauction, and approved the transfer to Leap of four F-Block licenses
covering portions of North and South Carolina, in each case subject to the
fulfillment of certain conditions. In October 1999, the FCC issued the 36
reauction licenses to Leap.

     Each of the conditions imposed by the FCC has been satisfied except for the
condition that Leap reduce its debt to QUALCOMM to 50% or less of its
outstanding debt by January 2001 and except for Leap's continuing obligation,
during the designated entity holding period for its C-Block and F-Block spectrum
licenses, to ensure that persons who are or were previously officers or
directors of QUALCOMM do not comprise a majority of Leap's Board of Directors or
a majority of its officers. Leap anticipates satisfying the debt reduction
condition through additional financing activities, but Leap cannot guarantee
that it will be able to reduce its debt to QUALCOMM to the required level. If
Leap fails in the future to meet any of the conditions imposed by the FCC or
otherwise fails to maintain its qualification to own C-Block and F-Block
licenses, that failure would have a material adverse effect on Leap's financial
condition and business prospects.

     Various parties, including the U.S. Small Business Administration,
previously challenged Leap's qualification to hold C-Block and F-Block licenses,
and a wireless operating company has requested that the FCC review its order. In
addition, one or more of such parties may appeal the FCC's order approving
Leap's acquisition of C-Block and F-Block licenses. Leap cannot assure investors
that it will prevail in connection with any such appeal or that it will remain
qualified to hold C-Block or F-Block spectrum licenses.

                                        4
<PAGE>   6

     Competition. The U.S. telecommunications industry is characterized by
intense competition. Leap's planned service will compete with some or all of the
services offered by the historic landline operators. Leap will compete directly
with other wireless providers in each of its markets, many of whom have greater
resources than Leap and entered the market before Leap. A few of Leap's
competitors operate wireless communications networks covering most of the United
States. Competitors' earlier entry and broader presence in the U.S.
telecommunications market may have a negative effect on Leap's ability to
successfully implement its strategy. In addition, other wireless providers could
attempt to implement Leap's strategy of providing local service at a flat-rate.
Providers who offered such a service in Leap's market areas would directly
compete against Leap in its market niche. Also, some competitors will likely
market other services, including cable television access, landline telephone
service and Internet access, that Leap does not currently intend to market. Leap
also expects to compete with new entrants to the U.S. wireless market as well as
other telecommunications technologies, including paging, enhanced specialized
mobile radio and global satellite networks.

  CHASE TELECOMMUNICATIONS

     General. Through a subsidiary, Chase Telecommunications Holdings, Inc. owns
spectrum licenses covering approximately 6.6 million POPs in a region that
includes approximately 98% of Tennessee. Leap currently owns 7.2% of Chase
Telecommunications Holdings and, in December 1998, Leap agreed to purchase
substantially all the assets of Chase Telecommunications Holdings, including its
spectrum licenses and all of the stock of its operating company, Chase
Telecommunications, Inc. Because the pending acquisition involves the transfer
of licenses, it is subject to approval by the FCC. Leap filed an application for
approval of the license transfers with the FCC in September 1999.

     Chase Telecommunications began offering wireless service in Chattanooga in
October 1998. In March 1999, Chase Telecommunications re-launched its service,
offering the Cricket(SM) concept in Chattanooga, Tennessee under an agreement
that requires the management of Chase Telecommunications to control the business
until Leap's proposed acquisition receives all necessary governmental approvals
and is completed.

     Chase Telecommunications has begun efforts to expand the Cricket(SM)
service to other markets in Tennessee and currently expects to launch service in
Nashville early in 2000.

     Market Opportunity. Nashville, Memphis, Knoxville and Chattanooga account
for approximately 4.8 million of the 6.6 million POPs covered by the Chase
Telecommunications Holdings' licenses. The state of Tennessee is situated in the
growing Southeast with a diverse economic base including manufacturing,
services, retail and wholesale trade, transportation, finance and agriculture.
Tennessee's personal income per capita grew 16.2% in real terms between 1990 and
1997 compared to 10.0% for the United States as a whole.

     Strategic Partners. Chase Telecommunications was founded by Tony Chase, the
chairman and CEO of Faith Broadcasting Corporation which operates radio
communications licenses in several major markets in Texas. Leap expects to
continue to maintain and benefit from its relationship with Mr. Chase after the
licenses are transferred.

     Leap's Rights and Interests. Leap does not have a right to representation
on the board of Chase Telecommunications Holdings or the board of Chase
Telecommunications, although it participates in the management and operation of
Chase Telecommunications under the terms of the management agreement described
above. If the FCC does not approve the transfer of the Chase Telecommunications
Holdings' licenses, Leap has the right to continue in its role as manager until
December 2005.

     Capital Requirement and Project Investments. Until the completion of Leap's
pending acquisition, Chase Telecommunications plans to finance the construction
and operation of its networks in Tennessee through borrowings from Leap and its
subsidiaries. Leap has entered into a credit facility with Chase
Telecommunications under which Leap has agreed, at its discretion, to provide
working capital to Chase Telecommunications. The parties have agreed in
principle to increase the maximum principal amount that may be drawn under the
facility to $45 million. Borrowings under the facility bear interest at prime
plus 4.5%. The borrowings are collateralized by substantially all of the assets
of Chase Telecommunications and are

                                        5
<PAGE>   7

subordinated in right of payment to amounts Chase Telecommunications owes to
QUALCOMM under an equipment financing agreement. At August 31, 1999, borrowings
under the working capital facility totaled $36.1 million, including $3.3 million
of accrued and capitalized interest. In addition, until the completion of Leap's
pending acquisition, a Leap subsidiary plans to purchase equipment and services
required by Chase Telecommunications under the subsidiary's existing equipment
purchase and financing agreements, and to resell the equipment and services to
Chase Telecommunications on substantially similar terms, including financing.

     Competition. Chase Telecommunications faces and expects to face competition
in its markets from current and potential market entrants including, among
others, Sprint Spectrum, Power Telecom, AT&T, Bell South and Alltel. Leap
believes that these competitors currently are or will soon begin operating
networks in the territories served or to be served by Chase Telecommunications.
Additionally, FCC rules allow licensees to partition or disaggregate their
spectrum. If other licensees create partitioned or disaggregated licenses, this
could increase the number of competitors and the types of competition in Chase
Telecommunications' markets.

  PEGASO

     General. Leap currently owns 28.6% of PEGASO, a joint venture formed to
construct and operate a wireless communications network in Mexico. In October
1998, a wholly owned subsidiary of PEGASO acquired nationwide PCS licenses in
Mexico for approximately U.S. $221 million (based on exchange rates in effect on
the dates the license payments were made). PEGASO launched operations in three
of Mexico's four largest cities in 1999: Tijuana in February, Guadalajara in
August and Monterrey in September. PEGASO expects to launch service in Mexico
City, the country's largest city, near the end of 1999. PEGASO plans to
construct and operate wireless communications systems in additional metropolitan
areas as well as tourist destinations and major border cities, subject to the
availability of additional capital.

     In bidding for its licenses, PEGASO agreed to provide coverage to
municipalities containing at least 20% of the total population of most of the
licensed regions by October 2001 and to provide coverage to municipalities
containing at least 50% of the total population of most of the licensed regions
by October 2003. Leap cannot assure investors that PEGASO can complete these
construction projects for the amount budgeted or on a timely basis.

     PEGASO has signed a roaming agreement with Sprint PCS that will enable
PEGASO customers to use Sprint PCS's nationwide wireless network in the U.S. and
will allow Sprint PCS customers to roam on PEGASO's network in Mexico.

     Market Opportunity. In early 1998, the Mexican government auctioned
additional wireless communications licenses in each of the nine regions of
Mexico to allow additional competition in the mobile wireless market. PEGASO
acquired nationwide PCS licenses in these auctions. Mexico's population of
approximately 99 million people is approximately 70% urban with approximately
50% living in Mexico City, Monterrey and Guadalajara. In 1998, Mexico's
teledensity was approximately 10.4% and its cellular penetration was
approximately 3.5%.

     Strategic Partners. In addition to Leap, Corporativo del Valle de Mexico,
S.A. de C.V., an affiliate of Grupo Televisa, and Pegaso Comunicaciones y
Servicios, S.A. de C.V. have interests in PEGASO. Grupo Televisa is the largest
media company in the Spanish-speaking world and is a major participant in the
international entertainment business. Pegaso Comunicaciones y Servicios is
96%-owned by Alejandro Burillo Azcarraga, a member of the Leap board of
directors, and is affiliated with Grupo Pegaso, a private investment group with
investments in various industries including cable television, communications,
retail electronics, real estate, sports and entertainment. Leap management
believes that the strong financing resources of Corporativo del Valle de Mexico
and Pegaso Comunicaciones y Servicios, as well as their political access in
Mexico, provide PEGASO critical resources and relationships for assisting the
network build-out and in marketing and distributing PEGASO's wireless services.
Citicorp, the Latin America Infrastructure Fund and Nissho Iwai have also
invested in PEGASO.

                                        6
<PAGE>   8

     Leap's Rights and Interests. Leap, through a wholly owned subsidiary,
currently owns a 28.6% interest in PEGASO and has invested $100 million of the
$350 million of capital that has been contributed by the members of the joint
venture. Leap expects that its ownership interest in PEGASO will be reduced in
the future. Several existing investors, other than Leap, are committed to
contribute an additional $50 million of financing by August 2000 and PEGASO is
currently seeking additional debt and equity financing.

     Leap has agreed to provide operator services to PEGASO and in turn has
subcontracted those services to a subsidiary of GTE. GTE is one of the world's
largest publicly traded international telecommunications operators, with
investments and operations in the United States and many other parts of the
world.

     Capital Requirements and Projected Investments. PEGASO has already raised
or obtained commitments for substantial amounts of capital. To date, the members
of the joint venture have contributed $350 million of equity, and members other
than Leap have committed an additional $50 million of equity contributions. In
addition, QUALCOMM and another equipment vendor have agreed to provide
approximately $580 million of secured equipment financing to the venture, a
portion of which has already been advanced to the company. In May 1999, a PEGASO
subsidiary also entered into a $100 million working capital facility with an
equipment vendor and several banks. To complete the build-out, launch and
operation of its planned networks, however, PEGASO will need to obtain
substantial additional capital.

     PEGASO expects to fund a large portion of its development and operating
activities in fiscal 2000 with cash from operations, proceeds of the recent $50
million investment, and borrowings under the $100 million working capital
facility. In addition, PEGASO is seeking additional debt and equity financing,
including additional vendor financing.

     Regulatory Environment. The Mexican Comision Federal de Telecomunicaciones
auctioned four new PCS licenses in the 1.9GHz band and four new wireless local
loop or WLL licenses in the 3.4GHz band beginning in November 1997. PEGASO
successfully purchased nationwide PCS licenses in the auctions. Mexico's Federal
Telecom Law provides the underlying basis for telecommunications competition in
Mexico. The Federal Telecom Law is designed to provide a pro-competitive
regulatory environment in the Mexican wireless services market.

     Telmex, the government telecommunications operator, is required by Mexico's
Federal Telecom Law to interconnect competing cellular operators to the landline
public switch telephone network. Interconnect agreements are supervised and
approved by the Secretaria de Comunicaciones y Transportes, also known as the
SCT, the government ministry responsible for regulating the telecommunications
sector and licensing new competitors. While cellular tariffs are no longer
regulated in Mexico, the rates must still be registered with the SCT. Mexico
currently restricts foreign voting ownership of telecommunications networks and
services to 49%.

     Competition. Following the Mexican government's recent wireless auctions,
there is one existing nationwide wireless operator, Telmex, which operates
through its subsidiaries Telcel and Dipsa; one carrier, Iusacell, with a large
mixed band footprint (four 800 MHz licenses and two 1900 MHz licenses); and
PEGASO, which holds a nationwide PCS license. In addition, Unefon has been
granted nationwide licenses, but cannot launch service until December 1999. The
Mexican government's right to issue licenses to Unefon is being challenged
because the government granted Unefon additional time to pay required license
fees after Unefon failed to comply with the payment schedule originally
established in connection with the auction. In addition, there are several
regional wireless carriers who offer wireless service in one or more of Mexico's
nine regions but who do not have a broad national presence.

  SMARTCOM

     General. In 1997, SMARTCOM, a wholly owned indirect subsidiary of Leap,
acquired a nationwide license to offer PCS services in Chile. SMARTCOM's
nationwide system began operation in September 1998 and had approximately 42,000
subscribers on August 31, 1999. In April 1999, Leap increased its ownership of
SMARTCOM from 50% to 100% when Leap's Chilean subsidiary purchased 50% of
SMARTCOM from

                                        7
<PAGE>   9

Telex-Chile, a Chilean telecommunications company, and an affiliate of
Telex-Chile, for $28 million and a $22 million interest-free note payable in
three years.

     SMARTCOM has experienced reliability problems with respect to its network
infrastructure equipment. Leap and SMARTCOM are working with equipment vendors
to address these problems, which have not yet been resolved. SMARTCOM is
upgrading existing equipment and purchasing additional equipment which it
expects to resolve the problems, enhance the quality and reliability of its
system and accommodate expected subscriber growth. Based upon its experience
with other operating company infrastructure configurations, Leap believes but
cannot guarantee that the upgrade and expansion will correct the reliability
problems that SMARTCOM has experienced.

     Market Opportunity. Chile is considered by many to be a technology leader
in Latin America. It has a stable economy and a regulatory environment that is
friendly to foreign investors. Chile has a population of approximately 15
million people. In excess of 70% of the population is concentrated in the center
of the country in the Santiago and Valparaiso regions. Current teledensity is
approximately 21.1%. Current wireless penetration in Chile is approximately
6.5%.

     Capital Requirements and Projected Investments. As discussed above,
SMARTCOM is in the process of upgrading existing equipment and purchasing
additional equipment to enhance the reliability of its system and to accommodate
expected subscriber growth. Leap intends to finance the planned upgrade and
expansion, as well as the operation of SMARTCOM's network in fiscal 2000,
through borrowings under Leap's credit agreement with QUALCOMM, the proceeds of
equipment financing agreements that Leap expects to negotiate in connection with
planned equipment purchases by SMARTCOM, and capital from additional financing
transactions. Leap and QUALCOMM are currently negotiating a new equipment
financing agreement for SMARTCOM, and SMARTCOM has engaged an investment banker
to assist it in selling equity. SMARTCOM is also exploring other capital raising
alternatives. Leap cannot assure investors that SMARTCOM will obtain additional
vendor funding or conclude a sale of equity or other financing transaction in
fiscal 2000. If SMARTCOM does not obtain additional financing in fiscal 2000,
Leap expects to delay or reduce the scope of SMARTCOM's planned expansion.

     Regulatory Environment. The Subsecretaria Telecomunicaciones regulates the
basic telecommunications network in Chile. In April 1997, Subsecretaria
Telecomunicaciones awarded three licenses for PCS (1900MHz) mobile operations in
Chile -- one to SMARTCOM and two to affiliates of Entel Cellular. In addition,
three major cellular operators, including Entel Cellular, were previously
licensed by the government and are operating in Chile. The regulatory
environment in Chile is considered to be stable, reliable and friendly to
foreign investment.

     Competition. In addition to SMARTCOM, there are three major operators of
wireless services in Chile, each of which effectively provides nationwide
service. CTC/Startel operates a nationwide cellular system. Bell South operates
in central Chile, but has acquired the cellular license for the regions outside
of Santiago from Entel Cellular. Bell South has an existing roaming agreement
with Entel Cellular that will allow it to effectively provide nationwide
coverage while it builds out its own nationwide network. In addition to these
cellular services, Entel launched a commercial PCS service using GSM technology
in March 1998. A second PCS license, also controlled by Entel, has not been
built out or put into operation.

OTHER BUSINESSES

     Through a subsidiary, Leap owns a 35% interest in Orrengrove Investments
Limited, which in turn owns a 60% interest in three related companies referred
to as the Transworld Companies. The Transworld Companies have been seeking to
establish a domestic long-distance business in Russia. In December 1998, they
launched limited long-distance service between Moscow and Perm, a region of
three million people west of Moscow. The third party satellite that the
companies used to provide long distance service failed in April 1999. As a
result of the failure, the Transworld Companies began using fiber lines to
provide long distance services on a short-term basis and they began to explore
long-term alternatives to the satellite transmission equipment they previously
used. The directors of the Transworld Companies voted to liquidate the companies
after reviewing a series of alternative business plans that did not meet their
minimum financial performance
                                        8
<PAGE>   10

criteria. As a result, Leap wrote down its investment in Orrengrove to the
proceeds Leap expects to receive in connection with the pending liquidations.

     Through another subsidiary, Leap also owns a 35% interest in Metrosvyaz
Limited, a company that is attempting to establish joint ventures in Russia to
construct and operate networks providing wireless local loop service. Metrosvyaz
was funding its activities through vendor financing from an equipment supplier
and a working capital facility from Leap. As described in greater detail in
"Item 3. Legal Proceedings," Leap has ceased funding loans to Metrosvyaz and, as
a result, has written-off its remaining investment in Metrosvyaz.

     In August 1999, Leap sold its subsidiary, OzPhone Pty. Limited, for $16.0
million. Leap had invested approximately $6.9 million in OzPhone prior to the
sale. Leap concluded that it could achieve greater shareholder return through
this sale than it could through years of continued investment in and development
of OzPhone. Although OzPhone owned spectrum licenses, it had not yet introduced
service.

RELATIONSHIP BETWEEN QUALCOMM AND LEAP

     To transfer the business of Leap from QUALCOMM to Leap, QUALCOMM and Leap
entered into various agreements that are described below. The agreements have
been amended from time to time, including recent changes required by the FCC as
a condition to allowing Leap to acquire specific wireless operating licenses. In
May 1999, QUALCOMM sold its network infrastructure division to Ericsson. In
connection with that sale, QUALCOMM transferred to Ericsson its rights to sell
network infrastructure equipment to Leap and its operating companies.

     QUALCOMM's relationship as a lender to Leap and its operating companies
gives QUALCOMM significant influence over Leap. Leap's relationships with
QUALCOMM may also create conflicts of interest between Leap and QUALCOMM.

  SEPARATION AND DISTRIBUTION AGREEMENT

     Immediately before the distribution of Leap common stock to QUALCOMM's
stockholders, QUALCOMM and Leap entered into the Separation and Distribution
Agreement. The Separation and Distribution Agreement governed the principal
transactions required to effect the separation of the companies and the
distribution, and other agreements governing the relationship between the
parties.

     To effect the separation of the companies, QUALCOMM transferred some of its
businesses and ventures to Leap. QUALCOMM also contributed to Leap the
following:

     - $10 million in cash;

     - QUALCOMM's right to receive payment of approximately $113 million of debt
       from the operating companies;

     - QUALCOMM's rights under specific agreements relating to the business and
       ventures of Leap; and

     - other assets.

     QUALCOMM's performance as an equipment vendor is not a condition of payment
to Leap under the notes and other debt transferred. Leap did not receive any
intellectual property in connection with the separation of the companies, and
QUALCOMM retained all rights not expressly transferred regarding any and all
agreements with Leap's operating companies.

     In connection with the transfer of assets and rights by QUALCOMM, Leap
issued a warrant to QUALCOMM to purchase 5,500,000 shares of Leap common stock
for $6.11 per share. In March 1999, in exchange for consideration valued at $5.4
million, QUALCOMM agreed to amend the warrant to reduce the number of shares
which may be acquired upon exercise of the warrant to 4,500,000. The warrant is
currently exercisable and remains exercisable until 2008. QUALCOMM has agreed
that it will not exercise the warrant in a manner that would cause QUALCOMM and
its officers and directors to collectively hold more than 15% of Leap's
outstanding common stock.

                                        9
<PAGE>   11

     In the Separation and Distribution Agreement, Leap also assumed some
liabilities of QUALCOMM, including: (1) funding obligations to Leap's operating
companies totaling approximately $75 million; (2) QUALCOMM's rights and
obligations to manage Leap's operating companies; and (3) $2 million of accrued
liabilities regarding Leap's employees.

     The Separation and Distribution Agreement also provides for (1) releases of
claims of each party against the other; (2) the allocation of potential
liabilities; and (3) indemnification rights between the parties.

     The Separation and Distribution Agreement also provides that, in
international markets, Leap will deploy, and will cause its affiliates to
deploy, only systems using cdmaOne until January 1, 2004. CdmaOne is the
original standard for fixed or mobile wireless communications systems based on
or derived from QUALCOMM's CDMA technology and successor standards that QUALCOMM
has adopted. The Telecommunications Industry Association and other recognized
international standards bodies have adopted cdmaOne as an industry standard.
Leap also agreed that, in international markets, it would invest only in
companies using cdmaOne systems until January 1, 2004.

     Under the Separation and Distribution Agreement, Leap also granted QUALCOMM
a non-exclusive, royalty-free license to any patent rights developed by Leap or
its affiliates. In addition, under the Separation and Distribution Agreement,
Leap Wireless granted QUALCOMM a right of first refusal for a period of three
years with respect to proposed transfers by Leap of its investments and joint
venture interests. Leap further agreed to take an active role in the management
of companies in which it holds stock or joint venture interests. The parties
also generally agreed that, for a period of three years following the spin-off
of Leap, neither party would solicit or hire employees of the other.

     Under the Separation and Distribution Agreement, the parties agreed that if
specific events occur by March 2000, QUALCOMM would transfer its ownership
interest in Telesystems of Ukraine to Leap. As a result of continued
difficulties between QUALCOMM and the other partners in Telesystems of Ukraine,
Leap believes that it is unlikely that QUALCOMM's interest in Telesystems of
Ukraine will be transferred to Leap.

  CREDIT AGREEMENT

     Immediately before the distribution of Leap common stock to QUALCOMM's
stockholders, Leap entered into a credit agreement with QUALCOMM. The credit
agreement consists of two sub-facilities. Leap may use the working capital
sub-facility to borrow up to $35.2 million from QUALCOMM. Leap may only use the
proceeds from the working capital sub-facility to meet its normal working
capital and operating expenses. These normal expenses include salaries and
overhead, but exclude strategic investments, substantial acquisitions of capital
equipment and the acquisition of telecommunications licenses. The investment
capital sub-facility enables Leap to borrow up to $229.8 million from QUALCOMM.
Leap may only use the proceeds from the investment capital sub-facility to make
identified portfolio investments. Amounts available under the investment
sub-facility are allocated to specific Leap projects and may not be reallocated
to other projects without QUALCOMM's written consent. As one of the conditions
to the FCC's recognition of Leap as a designated entity qualified to hold
C-Block and F-Block licenses of PCS spectrum, Leap must take steps so that by
January 2001, QUALCOMM holds no more than 50% of Leap's outstanding debt
obligations.

     Amounts borrowed under the credit agreement are due and payable in
September 2006, unless the maturity of the loans is accelerated pursuant to the
provisions of the credit agreement. The credit agreement required a 2%
origination fee. QUALCOMM has a security interest in substantially all of the
assets of Leap for so long as any amounts are outstanding under the credit
agreement. Amounts borrowed under the credit agreement bear interest at a
variable rate equal to LIBOR plus 5.25% per annum. Interest is payable quarterly
beginning September 30, 2001. Before this time, accrued interest is added to the
principal amount outstanding. If QUALCOMM assigns more than 10% of the total
funding commitments to other lenders, Leap must pay a commitment fee to the
lenders on unused balances under the credit agreement.

                                       10
<PAGE>   12

     The credit agreement contains operating covenants, including restrictions
on the ability of Leap to incur debt, merge, consolidate or transfer
substantially all of its assets, create, incur or permit the existence of liens
or pay dividends. Under the credit agreement, Leap agreed that it will not
permit the quotient obtained by dividing its total debt by total capitalization
to exceed the following level during the indicated period:

<TABLE>
<CAPTION>
                        PERIOD                          LEVEL

After February 23, 2002...............................   50%
</TABLE>

     The terms total debt and total capitalization are each defined in the
credit agreement.

     Leap was in compliance with the financial covenant as of August 31, 1999.
In addition, the credit agreement limits Leap's use of borrowed funds, restricts
Leap's joint venture and stock ownership, and imposes other restrictions on the
operation of Leap's business. Further, if Leap sells some of its assets, it must
prepay the credit agreement with a percentage of the proceeds.

  MASTER AGREEMENT REGARDING EQUIPMENT ACQUISITION

     The Master Agreement Regarding Equipment Acquisition contains the
obligations of Leap regarding the purchase and sale of terrestrial-based cdmaOne
infrastructure and subscriber equipment. As a result of QUALCOMM's sale of its
network infrastructure division to Ericsson, Leap owes some purchase obligations
to Ericsson with respect to network equipment and to QUALCOMM with respect to
subscriber equipment. Under the Master Agreement Regarding Equipment
Acquisition, Leap generally agreed that:

     - For five years, it will purchase at least 50% of its requirements for
       infrastructure equipment from Ericsson and 50% of its requirements for
       subscriber equipment from QUALCOMM.

     - For each initial investment by Leap made before October 2002 in a
       wireless telecommunication entity operating in the United States, Leap
       will require the U.S. operator to enter into an equipment requirements
       agreement with QUALCOMM and Ericsson. The equipment requirements
       agreement will require the U.S. operator to purchase at least 50% of its
       requirements for infrastructure equipment from Ericsson and 50% of its
       requirements for subscriber equipment from QUALCOMM, in each case for a
       five year period.

     - For each investment by Leap in a U.S. operator of wireless communications
       made after October 2002, Leap will attempt to require the U.S. operator
       to provide Ericsson and QUALCOMM with an opportunity to bid on its
       requirements for infrastructure equipment and subscriber equipment,
       respectively. Leap also will encourage the U.S. operator to acquire
       equipment from Ericsson and QUALCOMM.

     Leap and the U.S. operating companies in which it invests must comply with
these requirements only if Ericsson's bid for the infrastructure equipment and
related services or QUALCOMM's bid for subscriber equipment is less than or
equal to the lowest competing bid that Leap or its operating company would
accept; provided, however, until QUALCOMM has received contracts from Leap and
the companies in which it invests for at least $250 million of subscriber
equipment for use in the United States, Leap and the U.S. operating companies in
which it initially invests before 2002 must comply with these requirements if
QUALCOMM's bid is 110% or less than the lowest competing bid Leap or such other
company would accept.

     Until the earlier of (1) October 2002 and (2) the date on which Leap
receives an aggregate of $60 million of financing from parties other than
QUALCOMM, Leap must require each wireless telecommunication entity operating
outside the United States in which Leap initially invests to enter into an
equipment requirements agreement with QUALCOMM and Ericsson. The equipment
requirements agreement will provide that the foreign operator of wireless
communications will purchase at least 50% of its requirements for infrastructure
equipment from Ericsson and 50% of its requirements for subscriber equipment
from QUALCOMM, in each case for a five year period. The equipment requirements
agreement will also require the foreign operator to notify QUALCOMM if its bid
is not competitive, to explain how QUALCOMM must modify its bid to make it
competitive, and to give QUALCOMM the opportunity to submit a modified bid. If

                                       11
<PAGE>   13

Leap makes an initial investment in a wireless communications company operating
outside of the United States after the date described above, Leap will seek to
provide QUALCOMM and Ericsson with an opportunity to bid on the foreign
operator's infrastructure and subscriber equipment. Leap will also encourage the
foreign operator to acquire its equipment from QUALCOMM and Ericsson. The
obligations of all the foreign operators will depend on QUALCOMM and Ericsson
providing competitive prices.

     All the obligations of Leap and its operating companies regarding equipment
purchases under the Master Agreement Regarding Equipment Acquisition will expire
in September 2007.

     If Leap or one of its operating companies attempts to acquire equipment on
a "bundled" basis, then Ericsson and QUALCOMM are entitled, in some cases, to
respond separately to each portion of the proposed bundled acquisition. If Leap
does not attempt to acquire the equipment on a competitive basis from multiple
vendors, but instead decides to negotiate exclusively with Ericsson or QUALCOMM,
then Ericsson or QUALCOMM, as applicable, will offer and sell the equipment to
Leap on a "most favored pricing" basis.

  EMPLOYEE BENEFITS AGREEMENT

     The Employee Benefits Agreement between QUALCOMM and Leap governs the
employee benefit obligations of Leap for employees assigned to Leap. Under the
Employee Benefits Agreement, Leap assumed and agreed to pay all liabilities
relating to former employees of QUALCOMM employed by Leap. The Employee Benefits
Agreement also required Leap Wireless to adopt a 401(k) plan similar to
QUALCOMM's plan. In addition, Leap granted options to purchase shares of Leap
common stock to holders of options to purchase shares of QUALCOMM common stock.

  TAX AGREEMENT

     The Tax Agreement between QUALCOMM and Leap generally requires QUALCOMM to
pay all federal, state, local and foreign taxes relating to the businesses
conducted by QUALCOMM or its subsidiaries for any taxable period, excluding: (1)
taxes relating to Leap and its U.S. subsidiaries after the distribution of Leap;
(2) taxes relating to Leap's non-U.S. subsidiaries or any predecessor or
successor for all periods before and after the distribution of Leap (other than
regarding restructuring transactions incident to the distribution of Leap common
stock); and (3) taxes arising out of actions taken by, or in respect of, Leap or
any of its subsidiaries that cause negative tax consequences to QUALCOMM, Leap
or their respective subsidiaries regarding the distribution of Leap common stock
or the related transactions.

     The Tax Agreement further provides for cooperation regarding tax matters,
the exchange of information and retention of records that may affect the tax
liability of either party.

  CONVERSION AGREEMENT

     Under the Conversion Agreement, Leap agreed to issue up to 2,271,060 shares
of Leap common stock to the holders of the Trust Convertible Preferred
Securities of QUALCOMM Financial Trust I, a wholly owned statutory business
Trust of QUALCOMM, upon the conversion of their securities. Leap also agreed to
reserve and keep available Leap common stock for issuance and delivery upon that
conversion. Leap also filed and must keep effective a registration statement
covering the shares of Leap common stock issuable upon conversion of the Trust
Convertible Preferred Securities. If Leap determines that any event requires
changes to the registration statement so that the registration statement and the
prospectus contained therein do not contain a material misstatement or omission,
or if the continued effectiveness of the registration statement would require
Leap to disclose a material financing, acquisition or other material corporate
transaction or development (and the Leap Board of Directors has determined that
such disclosure is not in the best interests of Leap and its stockholders), then
Leap may suspend the issuance of Leap common stock issuable upon conversion of
the Trust Convertible Preferred Securities until Leap has prepared and filed,
and the SEC has declared effective, a post-effective amendment to the
registration statement which contains the required disclosures.

                                       12
<PAGE>   14

     Leap anticipates that all of the shares reserved for issuance under the
Conversion Agreement will be issued. Upon conversion of the Trust Convertible
Preferred Securities, QUALCOMM will receive benefit in the form of forgiveness
of debt, but Leap will receive no additional benefit or other consideration.

INFRASTRUCTURE PURCHASE AND FINANCE AGREEMENTS

     Subsequent to the end of fiscal 1999, a domestic subsidiary of Leap agreed
to purchase $330 million of infrastructure products and services from a major
telecommunications supplier. The supplier agreed to finance these purchases plus
additional working capital at an interest rate equal to LIBOR plus 3.5% to 4.25%
or a bank base rate plus 2.5% to 3.25%, in each case with the specific rate
based on the ratio of total indebtedness to EBITDA (earnings before interest,
taxes, depreciation and amortization). Principal payments are scheduled to begin
after three years with a final maturity after eight years. Repayment is weighted
to the later years of the repayment schedule. The supplier credit agreement is
secured by substantially all of the stock and assets of the companies operating
Leap's domestic wireless business and contains covenants and conditions typical
for a loan of this type.

     At the same time, Leap's subsidiary also agreed to purchase $330 million of
next-generation infrastructure products which are currently in development and
related services from a second major telecommunications supplier. Purchases from
the second supplier will be on substantially similar terms, including financing.
This second agreement is subject to approval of the supplier's board of
directors.

COMPETITION

     The wireless communications industry is very competitive and competition is
increasing. Many competitors have substantially greater resources than Leap and
its operating companies. Leap cannot assure investors that Leap or its operating
companies will compete successfully.

     Although the deployment of advanced telecommunications services is in its
early stages in many developing countries, Leap believes competition is
increasing as businesses and foreign governments realize the market potential of
telecommunications services. Leap's operating companies currently face
competition from existing wireless communications providers. In addition, a
number of large telecommunications companies are implementing programs to deploy
telecommunications services in both developing and developed countries. Leap's
operating companies also compete against landline carriers, including
government-owned telephone companies. In addition, Leap's operating companies
may face competition with technologies and services introduced in the future.
Although Leap's operating companies intend to use relatively new technologies,
newer technologies may make their technologies obsolete. Leap also expects the
price that its operating companies charge for their products and services in
some regions will decline over the next few years as competition increases in
their markets.

     In the United States, Leap will compete directly with other wireless
providers in each of its markets, many of whom have greater resources than Leap
and entered the market before Leap. A few of Leap's competitors operate wireless
communications networks covering most of the United States. Competitors' earlier
entry and broader presence in the U.S. telecommunications market may have a
negative effect on Leap's ability to successfully implement its strategy. In
addition, other wireless providers could attempt to implement Leap's strategy of
providing local service at a flat-rate. Providers who offered such a service in
Leap's market areas would directly compete against Leap in its market niche.
Also, it is likely that some competitors will market other services, including
cable television access, landline telephone service and Internet access, that
Leap does not currently intend to market. Leap also expects to compete with new
entrants to the U.S. wireless market as well as other telecommunications
technologies, including paging, enhanced specialized mobile radio and global
satellite networks.

     In addition, Leap believes that companies holding equity interests in
multiple operating companies throughout the world will be increasingly
predominant in the wireless communications industry and expects to experience
increasing competition from entities with structures resembling that of Leap.

GOVERNMENT REGULATION

     The construction, operation, sale and interconnection arrangements of
wireless communications systems and the grant, maintenance and renewal of
applicable licenses in each of the countries outside the United States in which
Leap has operations are regulated by governmental authorities in each country.
In some cases, the regulatory authorities also operate or control the operations
of the competitors of the operating companies. Changes in the current regulatory
environment of these markets or future judicial intervention, or regulations
affecting the pricing of the operating companies' services, could have a
material adverse effect on Leap. In addition, the regulatory framework and
authorities in the countries where Leap operates are relatively recent and,
therefore, the enforcement and interpretation of regulations, the assessment of
compliance, and the degree of flexibility of regulatory authorities are
uncertain. Further, changes in the regulatory framework may limit the ability to
add subscribers to developing systems. An operating company's failure to comply
with applicable governmental regulations or operating requirements could result
in the loss of licenses, penalties and fines or otherwise could have a material
adverse effect on Leap.

     The construction, operation, sale and interconnection arrangements of
wireless communications systems and the grant, maintenance and renewal of
applicable licenses in the United States are regulated to varying degrees by
state regulatory agencies, the FCC, the United States Congress and the courts.
This regulation is continually evolving and there are a number of issues on
which regulation has been or in the future may be suggested. The
Telecommunications Act of 1996 mandates significant changes in existing
regulations of the telecommunications industry to promote competitive
development of new service offerings to expand the availability of
telecommunications services and to streamline the regulation of the industry.
Leap cannot assure investors that the FCC, Congress, the courts or state
agencies having jurisdiction over the business of any of Leap's United States
operating companies will not adopt or change regulations or take other actions
that would adversely affect Leap's financial condition or results of operations.
Many of the FCC's rules relating to the businesses of Leap's U.S. operating
companies have not been tested by the courts and are subject to being changed by
Congressional action. In addition, FCC licenses are subject to renewal and
revocation. Leap cannot assure investors that the licenses of Leap's U.S.
operating companies will be renewed or not be revoked.

FINANCIAL INFORMATION CONCERNING SEGMENTS AND GEOGRAPHICAL INFORMATION

     Financial information concerning Leap's operating segments and the
geographic areas in which it operates is set forth in Note 13 to the
Consolidated Financial Statements in Leap's Annual Report to Shareholders for
the fiscal year ended August 31, 1999, which is incorporated in this report by
reference.

EMPLOYEES

     On October 1, 1999, Leap Wireless employed approximately 90 full time
employees, including the employees of its subsidiary Cricket Communications,
Inc. In addition, Leap's subsidiary SMARTCOM employed approximately 545
employees on that date.

ITEM 2. PROPERTIES

     The Company has leased approximately 50,000 square feet of office space in
San Diego, California, U.S.A. The Company currently leases this building for
sales, marketing, product development and administrative purposes. The Company
does not own any real property.

     SMARTCOM has leased approximately 50,000 square feet of office space in
Santiago, Chile, excluding a lease which is expiring in the near future and will
not be renewed. SMARTCOM uses this space for sales, marketing, customer service,
operations and administrative purposes, as well as for its primary
telecommunications switching equipment. In addition, SMARTCOM owns or leases
space at three sites in Temuco, Antafagasta and Punta Arena, Chile aggregating
approximately 10,000 square feet for additional switching equipment. SMARTCOM
also maintains numerous small sites throughout Chile for radio transmission

ITEM 3. LEGAL PROCEEDINGS

     Leap recently announced that it had stopped funding loans to Metrosvyaz and
had written-off its remaining $9.6 million investment in Metrosvyaz. Metrosvyaz
had not satisfied certain conditions required for funding and was in default
under its loan agreement with Leap. In addition, Leap had been prevented from
securing full reporting and documentation of performance, results and
expenditures of Metrosvyaz in spite of repeated efforts to obtain that
information. Preliminary results of a special investigation of Metrosvyaz also
disclosed serious irregularities, including unaccounted for funds and
questionable contracts and payments. On September 29, 1999, Leap issued a demand
for arbitration seeking a full accounting and damages from Metrosvyaz and one of
its directors with respect to these matters. It is too early to evaluate the
likely outcome of the arbitration or any adversarial proceeding that may arise
out of these matters.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted to a vote of security holders during the quarter
ended August 31, 1999.

ITEM 6. SELECTED FINANCIAL DATA

     The information required by this Item is set forth in the section headed
"Selected Financial Data" in Leap's Annual Report to Shareholders for the fiscal
year ended August 31, 1999, and is incorporated in this report by reference.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATION

     The information required by this Item is set forth in the section headed
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" in Leap's Annual Report to Shareholders for the fiscal year ended
August 31, 1999, and is incorporated in this report by reference.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Interest Rate Risk. Leap's exposure to market risk for changes in interest
rates relates primarily to its variable rate long-term debt obligations. For a
description of Leap's long term debt obligations, see Note 7 to the Consolidated
Financial Statements in Leap's Annual Report to Shareholders for the fiscal year
ended

                                       15
<PAGE>   17

August 31, 1999, which is incorporated in this report by reference. The general
level of U.S. interest rates and/or LIBOR affect the interest expense that Leap
recognizes on its variable rate long-term debt obligations. As of August 31,
1999, the principal amounts of Leap's variable rate long-term debt obligations
amounted to $210.3 million. An increase of 10% in interest rates would increase
Leap's interest expense for fiscal year 2000 by approximately $2.3 million. This
hypothetical amount is only suggestive of the effect of changes in interest
rates on Leap's results of operations in fiscal year 2000.

     Foreign Exchange Market Risk. The long-term debt obligations of Leap's
wholly owned Chilean subsidiary, SMARTCOM, which are denominated in the U.S.
dollar, are subject to the effects of currency fluctuations and may affect
reported earnings and losses. A significant change in the value of U.S. dollar
against the Chilean peso could result in a significant increase in the
consolidated expenses of Leap. As of August 31, 1999, SMARTCOM's long-term debt
obligations that were denominated in the U.S. dollar amounted to $101.7 million.
Leap's results of operations would be negatively impacted by approximately $11.9
million for fiscal year 2000 if the U.S. dollar were to appreciate against the
Chilean peso by 10%. This hypothetical amount is only suggestive of the effect
of currency fluctuations on Leap's results of operations in fiscal year 2000.

     Hedging Policy. Leap does not currently have a policy to systematically
hedge against foreign currency exchange rate or interest rate risks.

the address specified in Exhibit L of this Contract. All Purchase Orders shall
be governed by the terms and conditions of this Contract, unless otherwise
agreed by the parties in writing. Each Purchase Order shall specify, in
reasonable detail, the Products, Services or other items of Work to be provided
by the Vendor.

                3.2 Delivery under the Contract. The Vendor shall complete the
Work specified in each Purchase Order in accordance with the terms and
conditions of this Contract.

                3.3 Order Acceptance. All Purchase Orders submitted by Owner
shall be deemed to incorporate and be subject to the terms and conditions of
this Contract unless otherwise agreed in writing. All Purchase Orders, including
electronic orders, shall contain the information necessary for Vendor to fulfill
the order. All schedules and requested dates are subject to Vendor's
concurrence, provided that if orders are made within the agreed to lead times
specified in Exhibit L, Vendor shall not withhold its concurrence to the
requested dates. No provision or data on any Purchase Order or contained in any
documents attached to or referenced in any Purchase Order, or any subordinate
document (such as shipping releases), which is inconsistent with the terms of
this Contract shall be binding, except data necessary for Vendor to fill the
order. All such other data and provisions are hereby rejected. Electronic orders
shall be binding on Owner notwithstanding the absence of a signature, provided
that the parties have implemented a mutually acceptable electronic order process
and such orders deemed to be binding have been issued by Owner and accepted by
Vendor in accordance with the process agreed upon by the parties. Order
acceptance provisions, together with delivery schedules and intervals and
forecast requirements are set forth in Exhibit L.

        While it is Vendor's objective to provide Owner with an acknowledgment
of each order received, Owner shall advise Vendor to the extent that Owner
becomes aware of any missing or late notifications to ensure that the order has
not been lost.

        Changes made by Owner to an accepted Purchase Order shall be treated as
a separate order unless the parties expressly agree otherwise. If any such
change affects Vendor's ability to meet its obligations under the original
Purchase Order, any price, shipment date, or completion date quoted by Vendor
with respect to such original order is subject to change and shall be addressed
pursuant to the Change Order provisions below in Section 11.

                3.4 Forecasts. Owner shall provide to Vendor regular forecasts
of Owner's annual Product and Services needs. If the quantities ordered are more
than 25% greater than forecast quantities, Vendor shall be permitted a
reasonable extension of time to fulfill such orders and achieve the Milestones
required of Vendor hereunder.

                3.5 Deployment Plans and Milestones. The deployment plans and
intervals, together with the key milestones, order intervals, in respect of each
System, are set forth in Exhibit L.

                3.6 Inventory Control and Bar-coding. Vendor shall, at no
additional charge, pack and mark shipping containers in accordance with its
standard practices for domestic shipments. Where in order to meet Owner's
requests, Vendor packs and/or is required to mark shipping cartons in accordance
with Owner's specifications, Vendor shall invoice Owner additional charges for
such packing and/or marking. Vendor shall (a)



                                       16
<PAGE>   17

enclose a packing memorandum with each shipment and, if the shipment contains
more than one package, identify the package containing the memorandum, and (b)
mark Products as applicable for identification in accordance with Vendor's
marking specifications (for example, model/serial number and month, year of
manufacture).

                SECTION 4. SUBCONTRACTORS

                4.1 Subcontractors. The Vendor may subcontract any portion of
its obligations under this Contract, but no such subcontract shall relieve
Vendor from primary responsibility and liability for the performance of Vendor's
covenants and obligations under this Contract. Regardless of whether or not the
Vendor obtains approval from the Owner or a Subcontractor or whether the Vendor
uses a Subcontractor recommended by the Owner, use by the Vendor of a
Subcontractor shall not, under any circumstances: (i) give rise to any claim by
the Vendor against the Owner if such Subcontractor breaches its subcontract or
contract with the Vendor; (ii) give rise to any claim by such Subcontractor
against the Owner; (iii) create any contractual obligation by the Owner to the
Subcontractor; (iv) give rise to a waiver by the Owner of its rights to reject
any Defects or Deficiencies or Defective Work; or (v) in any way release the
Vendor from being solely responsible to the Owner for the Work to be performed
under this Contract.

                4.2 The Vendor's Liability. The Vendor is responsible for all of
its obligations under this Contract, including the Work, regardless of whether a
subcontract or supply agreement is made or whether the Vendor relies upon any
Subcontractor to any extent. The Vendor's use of Subcontractors for any of the
Work shall in no way increase the Vendor's rights or diminish the Vendor's
liabilities to the Owner with respect to this Contract, and in all events,
except as otherwise expressly provided for herein, the Vendor's rights and
liabilities hereunder with respect to the Owner shall be as though the Vendor
had itself performed such Work. The Vendor shall be liable for any delays caused
by any Subcontractor as if such delays were caused by the Vendor.

                4.3 No Effect of Inconsistent Terms in Subcontracts. The terms
of this Contract shall in all events be binding upon the Vendor regardless of
and without regard to the existence of any inconsistent terms in any agreement
between the Vendor and any Subcontractor whether or not and without regard to
the fact that the Owner may have directly and/or indirectly had notice of any
such inconsistent term.

                4.4 Assignability of Subcontracts to Owner. Vendor shall use
reasonable efforts to have each agreement between the Vendor and a Subcontractor
contain a provision stating that, in the event that the Vendor is terminated for
cause, convenience, abandonment of this Contract or otherwise, (i) each
Subcontractor shall continue its portion of the Work as may be requested by the
Owner and (ii) such agreement permits assignment thereof without penalty to the
Owner and, in order to create security interests, to third parties designated by
Owner, in either case at the option of the Owner and for the same price and
under the same terms and conditions as originally specified in such
Subcontractor's agreement with the Vendor.



                                       17
<PAGE>   18

                4.5 Removal of Subcontractor or Subcontractor's Personnel. The
Owner has the right at any time to request removal of a Subcontractor and/or any
of a Subcontractor's personnel from Work on the System upon reasonable grounds
and reasonable prior notice to Vendor. Such request (a "Request for Removal")
shall be in writing and shall specify the Owner's reasoning therefor. The Vendor
promptly shall issue a written response to any such Request for Removal,
specifying the reasoning for its disagreement or agreement, as the case may be,
with the reasoning contained in the Request for Removal. If the parties fail to
agree, this matter shall be handled in accordance with the dispute resolution
procedures in Section 23. The exercise of such right by the Owner shall have no
effect on the provisions of subsections 4.1 and 4.2.

                4.6 Subcontractor Insurance. The Vendor shall require its
Subcontractors to obtain, maintain and keep in force, during the time they are
engaged in providing Products and Services hereunder, insurance coverage of the
types and levels customary in the industry (provided that the maintenance of any
such Subcontractor insurance shall not relieve the Vendor of its other
obligations pursuant to this Contract). The Vendor shall, upon the Owner's
request, furnish the Owner with evidence of such insurance in form and substance
reasonably satisfactory to the Owner.

                4.7 Review and Approval not Relief of Vendor Liability. No
inspection, review or approval by the Owner permitted under this Contract of any
portion of the Work shall relieve the Vendor of any duties, liabilities or
obligations under this Contract, but nothing contained in this subsection shall
be deemed a bar of any waiver given by the Owner to the Vendor pursuant to and
in accordance with the terms of this Contract.

                4.8 Vendor Warranties. Except as otherwise expressly provided in
Section 18, the warranties of the Vendor pursuant to Section 18 shall be deemed
to apply to all Work performed by any Subcontractor as though the Vendor had
itself performed such Work and to all Products supplied by any third-party
vendor or other subcontractor as though the Vendor itself had supplied such
Products. Except as otherwise specifically provided in Section 18, the parties
agree that such warranties shall not be enforceable merely on a "pass-through"
basis but that Owner may, but shall not be obligated to, enforce such warranties
of any Subcontractor to the extent that the Owner determines that the Vendor is
not paying and/or performing its warranties; provided that any such election by
the Owner shall not relieve the Vendor from any obligations or liability with
respect to any such warranty.

                4.9 Payment of Subcontractors. The Vendor shall make all
payments it is contractually required to make to all Subcontractors (except in
the case of legitimate disputes between the Vendor and any such Subcontractor
arising out of the agreement between the Vendor and such Subcontractor) in
accordance with the respective agreements between the Vendor and its
Subcontractors such that no Subcontractor shall be in a position to enforce any
liens and/or other rights against the Owner, the System, any Products or any
part thereof.



                                       18
<PAGE>   19

                4.10 Copies. Subject to any confidentiality obligations insisted
upon by third party providers, including Subcontractors, Vendor will use its
good faith, reasonable efforts to provide Owner with any and all relevant
agreements, understandings, subcontracts and other documents pertaining to the
provision of Products or Services by a Subcontractor which Owner may reasonably
require in order for it to be provided with the information necessary to
exercise any of its rights under this Contract.

                4.11 Benefit of Subcontracts. In addition to anything else
provided for in this Contract, the Owner shall be entitled to the following
benefits and rights of the Vendor under its contracts with any applicable
third-party vendors or other Subcontractors: all rights to conduct in-house
tests, to receive notice of upgrades and enhancements and to purchase spare
parts; provided however, that the Vendor shall maintain sole responsibility for
all obligations and other duties under all such contracts.

                SECTION 5. PRICES AND PAYMENT

                5.1 Prices; Minimum Purchases. (a) The prices for the Products,
Services and other items of Work for the Contract Term are set forth in the B
Exhibits. The prices for Expansions and the Chattanooga Replacement, including
all Work to be performed in connection with the Chattanooga Replacement, are
also set forth in the B Exhibits. The Owner agrees that the aggregate amount of
all payments to the Vendor pursuant to Purchase Orders delivered to the Vendor
during the Contract Term shall be not less than Three Hundred Thirty Million

                5.2 Taxes. The Owner shall reimburse Vendor for all present or
future taxes, levies, imposts, deductions, charges, withholdings and liabilities
("Taxes") imposed on the Vendor by any Governmental Entity relating to the
provision of Products and Services by the Vendor to the Owner under this
Contract, provided, however, that the Owner shall not be liable for and shall
not pay or reimburse Vendor for any Taxes on or measured by the income or
receipts of the Vendor. If the Owner shall pay Taxes for which the Vendor
receives a credit, then the Vendor shall reimburse to the Owner an amount equal
to such credit.

                5.3 Payment. Payment for the Products and Services to be
supplied pursuant to this Contract shall occur as follows (in each case
following submission of an invoice by the Vendor which shall properly document,
to the reasonable satisfaction of the Owner, all the items included):

                (a) Products for Systems: except as set forth in subsections (b)
and (c) below,

                        (i) [*] of the amount of all Purchase Orders completed
        by the Vendor with respect to a Site shall be invoiced upon shipment of
        the Products in respect of such Purchase Orders;

<PAGE>   21

                        (ii) [*] of the amount of all Purchase Orders completed
        by the Vendor with respect to a Site shall be invoiced upon completion
        of Installation and Integration of the Products with respect to each
        Site;

                        (iii) [*] of the amount of all Purchase Orders completed
        by the Vendor with respect to a Site shall be invoiced upon the date
        Owner signs a Certificate of Substantial Completion in respect of the
        Products forming part of such Purchase Orders; provided that in the
        event that a Certificate of Substantial Completion is not issued within
        five (5) Business Days after the Guaranteed Substantial Completion Date
        because of a delay in reaching Substantial Completion solely
        attributable to the failure or lack of performance of Owner to satisfy
        its obligations and commitments in a timely manner, such amount shall be
        invoiced on the fifth (5th) Business Day following Substantial
        Completion; and

                        (iv) the balance of all amounts due Vendor pursuant to
        completed Purchase Orders with respect to Products for a System shall be
        invoiced upon Final Acceptance of such System.

                (b) Services: Services shall be invoiced as performed, or as
soon thereafter as practical but in no event more frequently than monthly,
provided that Installation and Integration Services and Optimization Services
will only be invoiced after the Owner signs a Certificate of Substantial
Completion in respect of the System for which such Services are rendered;
provided that in the event that a Certificate of Substantial Completion is not
issued within five (5) Business Days after the Guaranteed Substantial Completion
Date because of a delay in reaching Substantial Completion solely attributable
to the failure or lack of performance of Owner to satisfy its obligations and
commitments in a timely manner, such amount shall be invoiced on the fifth (5th)
Business Day following Substantial Completion.

                (c) Optional Software Features and Spares: The purchase price
for the initial Optional Software Features and Spares shall be invoiced after

for which such initial Optional Software Features and Spares are furnished;
provided that in the event that a Certificate of Substantial Completion is not
issued within five (5) Business Bays after the Guaranteed Substantial Completion
Date because of a delay in reaching Substantial Completion attributable solely
to the failure or lack of performance of Owner to satisfy its obligations and
commitments in a timely manner, such amount shall be invoiced on the fifth (5th)
Business Day following Substantial Completion.

                (d) Expansions (Growth):

                        (i) [*] of the amount of all Purchase Orders completed
        by the Vendor with respect to Products for which Vendor provides
        installation Services pursuant to an Expansion shall be invoiced upon
        delivery of such Products; and


[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.



                                       21
<PAGE>   22

                        (ii) [*] of the amount of all Purchase Orders completed
        by Vendor with respect to Products for which Vendor provides
        installation Services pursuant to an Expansion shall be invoiced upon
        completion of installation of such Products; and

                        (iii) 100% of the amount of all Purchase Orders
        completed by the Vendor with respect to Products for which Vendor
        provides no installation Services pursuant to an Expansion shall be
        invoiced upon delivery of such Products.

                (e) Payment of Invoices. Owner shall pay the invoiced amounts,
less any disputed amounts, within ten (10) days from the date of transmission of
Vendor's invoice. Delinquent payments are subject to a late payment charge after
thirty (30) days at the rate of [*] per month, or portion thereof, of the amount
due (but not to exceed the maximum lawful rate). Any disputed items which are
determined to be validly billed are due for payment based upon the original
invoice date.

                5.5 No Payment in Event of Material Breach. Subject to
Subsection 24.5, the Owner shall have no obligation to make any payment for any
Work with respect to which the Vendor is in material breach of this Contract
until and unless such breach is cured or waived by the Owner in accordance with
the terms of this Contract.

                5.6 In Revenue Payments. At any time during a period of delay
the Owner may, in its sole discretion, decide to place a System which is subject
to such delay into In Revenue Service. Such placement into In Revenue Service
shall constitute Substantial Completion only for purposes of the payment
obligations above, but shall not in any way relieve the Vendor of any of its
obligations under this Contract, including without limitation achieving a
Guaranteed Substantial Completion Date nor shall such In Revenue Service trigger
the commencement of the Initial Period.

                5.7 Currency and Place of Payment. Payments under this Contract
shall be made in US dollars and if such method of payment is acceptable to
Owner, Owner shall pay all amounts due Vendor hereunder using Electronic Funds
Transfer ("EFT"). EFT payments by Vendor shall be made to the following account
of Vendor or such other account as is subsequently designated by Vendor in
writing and, concurrent with the EFT payment, Owner shall fax a coy of the
remittal to Vendor's manager of cash operations at 770-750-4288:

                     SECTION 7. MODCELL/MINICELL REPLACEMENT

                7.1. Minicell/Modcell. For markets to be located in Chattanooga
and Nashville, Tennessee, for up to a maximum of [*] Sites, [*] shall de-install
and redeploy the minicells in such markets to a market area(s) of Owner's choice
at [*], and replace such minicells with modcells in accordance with this
Section. [*] shall be responsible for temporary warehousing of the de-installed
minicells at a location of Owner's choosing within the United States. [*] shall
be responsible, at [*], for transportation from the original location to such
warehouse, transportation from such warehouse to the new installation Site, and
re-installation at the new Site within the United States. [*] shall be
responsible for the cost of installation of the replacement modcells. In
addition, Vendor shall provide up to [*] refurbished 5 ESS(R) switches
engineered for up to 50 minicells and one carrier each at [*] for use in any of
Owner's markets at Owner's choice. [*] shall be responsible for the cost of
engineering and installation of such switches, at prices consistent with the
prices set out in Exhibit B-2 and B-3.

        Vendor shall reimburse Owner [*] incurred by Owner as a result of the
use of minicells in Nashville and Chattanooga, Tennessee, up until the
replacement of the minicells with modcells in such markets. In the event that
Owner delays the installation of modcells after they are made available by
Vendor, Vendor shall not be responsible for [*] incurred by Owner after the date
that the replacement is made available.

        During the time commencing on the date the minicells are decommissioned
from operation in the System, until the date that the minicells are installed in
the new reinstallation Site, the applicable Warranty Period remaining on such
Products, if any, will be suspended. Thereafter, upon reinstallation, the
Warranty Period shall continue for a period which is the greater of (i) the
remaining Warranty Period; and (ii) twelve months following reinstallation.

        During period from decommissioning to redeployment, Vendor will continue
to supply all Class A Upgrades, new Software loads, and other standard support
which would otherwise be provided pursuant to this Contract. Vendor shall, at

<PAGE>   25
[*] provide reasonable quantities of spares and training in light of the new
total network deployment of modcells and minicells.

        If the refurbished 5 ESS(R) switches to be delivered to Owner have not
been decommissioned immediately prior to the time that they are to be
refurbished and engineered, Vendor will provide Owner with a reasonable
opportunity to inspect the switches at the site where such switches are located,
to satisfy itself that such switches are in a reasonable state of repair and
will be fit for Owner's purposes; provided that the owner or operator of such
site consents to the site inspection. Owner may refuse to accept such a switch
that is not, in Owner's reasonable opinion, in such a satisfactory condition in
accordance with the foregoing. If the refurbished 5 ESS(R) switches to be
delivered to Owner have been decommissioned and removed from the prior
operator's network, Owner or, at Owner's request, a qualified third party
reasonably acceptable to both parties, shall have the right to conduct a
reasonable inspection on such switch, to determine whether the switches are in
such a satisfactory condition in accordance with the foregoing. If Owner
reasonably objects to the conditions of any of such switches, Vendor will either
obtain the necessary switches in a satisfactory condition, or take such other
actions as are necessary to satisfy Owner's objections.

                7.2 Tennessee Swap-out Credit. In connection with the swap-out
of the existing network in Tennessee, Vendor will make available to Owner
general purchase credits in the amount of [*] (the "Tennessee Swap-out
Credits"), to be applied against any invoice issued by Vendor during the initial
twenty four (24) months of the Contract term, provided that Credits shall not be
applied to any particular invoice in an amount greater than 20% of the net
invoiced amount; provided, however that Vendor will agree with reasonable
requests by Owner to either adjust the amount which can be applied to each
invoice in order to ensure that the entire amount of the Tennessee Swap-out
Credits are applied against invoices during such initial twenty four (24) month
period or extend the initial twenty four (24) in order to facilitate the entire
usage of the Tennessee Swap-out Credits.

                SECTION 8. SERVICES

                8.1 Transportation. The Vendor shall at the Vendor's sole cost
and expense provide for the transportation and delivery to the Sites of all the
Products to be delivered pursuant to, and in accordance with, each Purchase
Order and the terms of this Contract. In the event of any unusual Site
selections or requirements which require transportation arrangements out of the
ordinary course having regard to normal industry standards and practices (such
as non-standard crane requirements, helicopter transportation requirements to a
remote setting, etc.), Vendor shall arrange, subject to Owner's prior approval,
for such exceptional transportation requirements from local staging facilities
or warehouse locations to the unusual Site. Vendor shall notify Owner that it
believes, in good faith, that exceptional transportation arrangements are
necessary in the circumstances, and Vendor will consult with Owner on an
approved course of action to complete delivery. Owner shall be

    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       25
<PAGE>   26

responsible for all costs with respect to such exceptional transportation
requirements in excess of transportation costs applicable to a standard Site.

                8.2 Services. The Vendor shall provide the Services ordered by
Owner in accordance with the provisions of the Exhibit hereto in respect of such
Services, including, without limitation, the following Services: RF Design
Services as stated in Exhibit D, construction management and site construction
services as stated in Exhibit E, architectural & engineering services as stated
in Exhibit E, spectrum clearing and microwave relocation services as stated in
Exhibit E, Optimization Services as set forth in Exhibit G, Installation and
Integration services as set forth in Exhibit F and Wireless Support Services as
stated in Exhibit H.

                8.3 No Interference. The Vendor shall install all Equipment and
build each of the Systems so as to cause no unauthorized interference with or
obstruction to lands and thoroughfares or rights of way on or near which the
installation work may be performed. The Vendor shall exercise every reasonable
safeguard to avoid damage to existing facilities, and if repairs or new
construction are required in order to replace facilities damaged by the Vendor
due to its carelessness, negligence or willful misconduct, such repairs or new
construction shall be at the Vendor's sole cost and expense. Vendor understands
that many of the Sites may be co-located with other RF transmission facilities
and Vendor shall take all necessary precautions and safety measures to ensure
the safety of all of Vendor's and Subcontractors' personnel at such Sites. The
Owner shall use its reasonable best efforts to ensure that no other third
parties employed or engaged by the Owner hinder or delay the Vendor in the
performance of its installation obligations hereunder.

                Vendor represents and warrants that all Products furnished
hereunder shall comply, to the extent required, with the requirements of Part 24
of the Federal Communication Commission's Rules and Regulations (the "FCC
Rules") pertaining to personal communications services in effect upon delivery
of such Product. In addition, Vendor represents and warrants that a Product
furnished hereunder shall comply, to the extent required, with the requirements
of Subpart J of Part 15 of the FCC Rules in effect upon delivery of such
Product, including those sections concerning the labeling of such Product and
the suppression of radio frequency and electromagnetic radiation to specified
levels. Vendor makes no undertaking with respect to harmful interference caused
by (i) unauthorized installation, repair, modification or change or Products not
furnished by Vendor; (ii) Products being subject to misuse, neglect, accident or
abuse by other than Vendor; (iii) Products being used in a manner not in
accordance with operating instructions or in a suitable installation environment
or operations of other equipment in the frequency ranges reserved for Owner
within the applicable licensed area. Vendor assumes no responsibility under this
clause for items not specified or supplied by Vendor. The foregoing warranties
are collectively referred to as the "Compliance Warranty".

                Vendor shall, when appropriate, have reasonable access to
Owner's premises during normal business hours and at such other times as may be
agreed upon by the parties in order to enable Vendor to perform its obligations
under this Contract. Vendor shall coordinate such access with Owner's designated
representative prior to visiting such



                                       26

                SECTION 12. DISCONTINUED PRODUCTS AND CONTINUING PRODUCT SUPPORT

                12.1 Notice of Discontinuation. For a period of [*] for the 5
ESS(R) switch and [*] for all other Products furnished hereunder after the
Effective Date, but in no event less than [*] after the date of shipment, the
Vendor agrees to provide the Owner, or its affiliates as the case may be, not
less than one (1) year notice before the Vendor discontinues a Product
("Discontinued Products") furnished under this Contract. In respect of Products
manufactured by a third party vendor, the notice period may vary. Where the
Vendor offers a product for sale that is equivalent in Form, Fit and Function in
accordance with and pursuant to the Specifications, the notification period may
vary but in no event shall be less than sixty (60) days. In the event of the
foregoing, the Vendor shall continue to furnish Products fully compatible with
the relevant System Elements within the System at such time during the
appropriate [*] and [*] periods referenced above; provided that nothing
herein shall bar the Vendor from discontinuing individual items of Products as
provided in and pursuant to this subsection. In the event that Vendor
discontinues a Product, Vendor will meet with Owner and use reasonable, good
faith efforts to develop a mutually acceptable transition plan that takes into
account the Owner's existing investment in the item scheduled for
discontinuance.

                In addition to repairs provided for under any applicable
Warranty, Vendor shall offer repair Services and repair parts in accordance with
Vendor's repair and repair parts practices and terms and conditions then in
effect, for Vendor-manufactured Equipment furnished pursuant to this Contract.
Such repair Services and repair parts shall be available while Vendor is
manufacturing or stocking such Products or repair parts, but in no event less
than [*] for the 5 ESS switch and [*] for all other Products after such
Product's discontinued availability effective date. Vendor may use either the
same or functionally equivalent products or parts which are new, remanufactured,
reconditioned or refurbished in the furnishing of repairs or replacements under
this Contract.

                If during the agreed-to support period following the issuance of
notice of discontinuance, Vendor fails to provide repair parts and or repair
Services and a functionally equivalent replacement has not been designated,
Vendor shall so advise Owner, to allow Owner to plan appropriately, and if
Vendor is unable to identify another source of supply for such repair parts or
services, Vendor shall, in addition to any other right or remedy available to
Owner at law or in equity, provide Owner, at no additional charge to Owner, upon
request, with non-exclusive licenses for Product manufacturing to the extent
Vendor can grant such licenses, so that Owner will have sufficient information,
ability and rights to have such Discontinued Products manufactured, or obtain
such repair Service or repair parts from other sources. Such license shall
include appropriate non-disclosure and confidentiality covenants.

                12.2 Discontinuation During Warranty Period. If Vendor
discontinues the availability of a Product during that Product's Warranty Period
and Owner is required to purchase a replacement Product to replace the
Discontinued Product in order to maintain

 the same functionality of the Discontinued Product in a System, Vendor agrees
to grant Owner an additional [*] discount to be applied against the net price of
all Products required to be purchased by Owner as replacements for such
Discontinued Product, which additional discount shall be applied after the
determination of the lowest price available to Owner pursuant to this Contract,
excluding the application of any Tennessee Swap-Out Credits.

                SECTION 13. SOFTWARE; CONFIDENTIAL INFORMATION

                13.1 RTU License. Upon delivery of the Software, but subject to
payment of the license fees specified in Exhibit B-5, the Owner is hereby
granted a personal, non-exclusive, fully paid-up, multi-site (capability to move
Software from site to site on prior notice to Vendor) right to use license for
the Software ("RTU License"), to operate the specific Equipment, processor or
product line for which the licenses to use the Software are initially granted,
or temporarily on any comparable replacement if any such Equipment, processor or
product line becomes inoperative. Owner shall use such Software only for its own
internal business operation. The RTU License grants Owner no right to, and Owner
will not, sublicense such Software or modify, decompile, or disassemble Software
furnished as object code to generate corresponding source code provided in each
of the Systems. Except as provided below, no license is granted to Owner to use
the Software outside of the United States.

                In the event that Owner wishes to use the Software on associated
equipment outside of the United States or to transfer Software to an affiliate
or third party transferee located outside the United States, Vendor shall not
unreasonably withhold its consent to such use or transfer, provided that Vendor
or the transferee, as the case may be, enters into an appropriate license
agreement with an affiliate of Vendor carrying on business in the territory in
which the Software is to be located, on terms substantially similar to the RTU
License terms set forth herein, provided, however, that Owner acknowledges and
agrees that support and maintenance obligations set forth herein are only
applicable for Software resident on Equipment located within the United States.
Support and maintenance Services offered by Vendor's affiliates differs in
various different territories, and will be subject to the local practices
maintained in such territory.

                13.2 Owner's Obligations. The Owner agrees that the Software,
whether or not modified, and all copies thereof made by Owner, shall be treated
as proprietary to the Vendor, its Subcontractors or its suppliers, as
appropriate and the Owner shall:

                (a) Utilize the Software solely in conjunction with a System;
provided that the Vendor acknowledges that the Software shall be integrated
across interfaces with systems, equipment and software provided by other
suppliers and customers;


[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       32
<PAGE>   33

                (b) Ensure that all copies of the Software shall, upon any
reproduction by the Owner authorized by the Vendor and whether or not in the
same form or format as such Software, contain the same proprietary,
confidentiality and copyright notices or legends which appear on the Software
provided pursuant hereto; and

                (c) Hold secret and not disclose the Software to any person,
except to (i) such of its employees, contractors, agents or affiliates that are
involved in the operation or management of a System and need to have access
thereto to fulfill their duties in such capacity, or (ii) other Persons who need
to use such Software to permit integration of a System with systems and software
of other suppliers and customers; provided that such persons agree, or are
otherwise obligated, to hold secret and not disclose the Software to the same
extent as if they were subject to this Contract, and provided further that if
any such Person is a competitor of Vendor involved in the manufacture of
communications equipment, software or related services, Vendor must approve such
use on a case-by-case basis on commercially reasonable terms and such use shall
be subject to an appropriate non-disclosure agreement.

                (d) When and if the Owner determines that it no longer needs the
Software or if the Owner's license is canceled or terminated pursuant to the
terms of this Contract, return all copies of such Software to the Vendor or
follow reasonable written disposition instructions provided by the Vendor. If
the Vendor authorizes disposition by erasure or destruction, the Owner shall
remove from the medium on which Software resides all electronic evidence of the
Software, both original and derived, in such manner that prevents subsequent
recovery of such original or derived Software.

                (e) Owner shall not copy Software embodied in firmware and
unless otherwise specifically provided in this Contract, Owner is not granted
any right to modify Software furnished by Vendor under this Contract.

                13.3 Backwards Compatibility. The Vendor represents and warrants
(the "Software Backwards Compatibility Warranty") that each Software Maintenance
Release, Software Upgrade and Software Enhancement will be Backwards Compatible.
[***] Notwithstanding the foregoing, the Software Backwards Compatibility
Warranty does not apply to Products developed beyond 3G1X which are developed in
accordance with standards not yet finalized as of the date hereof.

                13.4 Transfer and Relocation. (a) In the event the Owner or any
successor to the Owner's title in the Products (i) elects to transfer a Product
to a third party, and where such Product shall remain in place and used for
substantially the same purpose as used by the Owner and where such third party
resides in the United States and is not a direct competitor of the Vendor
involved in the manufacture of communications equipment, software or related
services, or (ii) elects to transfer Products to an affiliate, the Owner may

transfer its RTU License for the Software furnished under this Contract for use
with such Product, without the payment of any additional Software right-to-use
fees by the transferee provided that Annual Maintenance Fees shall continue to
be calculated on the same basis. For example, if the RTU License for the
Software contains usage or per subscriber limits, or the processor to be used by
transferee requires additional memory or hard disk space additional payments or
purchases may be required. The following conditions shall apply to transfers and
relocations pursuant to this subsection 13.4:

                (A)     The right to use such Software may be transferred only
                        together with the Products with which the Owner has a
                        right to use such Software, and such right to use the
                        Software shall continue to be limited to use with such
                        Products;

                (B)     Before any such Software is transferred, the Owner shall
                        notify the Vendor of such transfer and the transferee
                        shall have agreed in writing (a copy of which shall be
                        provided to the Vendor) to keep the Software in
                        confidence and to corresponding conditions respecting
                        possession and use of Software as those imposed on the
                        Owner in this Contract; and

                (C)     The transferee shall have the same right to Software
                        warranty and Software maintenance for such Software as
                        the transferor, provided the transferee continues to pay
                        the fees, including recurring fees, if any, associated
                        with such Software warranty or maintenance pursuant to
                        this Contract.

                (b) Except as otherwise provided in this Contract, the Owner or
any successor to the Owner's title in the Products shall have no right to
transfer Software furnished by the Vendor under this Contract without the
consent of the Vendor, which consent shall not be unreasonably withheld. If the
Owner or such successor elects to transfer a Product purchased under this
Contract for which it does not under this Contract have the right to transfer
related Software, the Vendor agrees that upon written request of the transferee
of such Product, or of the Owner or such successor, the Vendor shall not without
reasonable cause fail to grant to the transferee a license to use such Software
with the Products, whether to be located within the United States or elsewhere,
upon payment of a relicensing fee to the Vendor on commercially reasonable terms
acceptable to Vendor.

                13.5 Termination and Survival. The rights and obligations of the
Owner under the RTU License shall survive the termination of this Contract,
regardless of the cause of termination provided Owner has met its material
obligations hereunder and has rendered all payments in accordance with this
Contract. In the event that Owner persistently and materially breaches its
confidentiality obligations hereunder with respect to the Software
notwithstanding the fact that Vendor will have provided Owner with prior written
notice describing the alleged material breaches and will have given Owner a
reasonable time, and in no event less than thirty (30) days, to cure any such
breaches, Vendor may terminate Owner's RTU License. In the event that Owner
fails to pay the Annual Release



                                       34
<PAGE>   35

Maintenance Fees (other than with respect to any periods for which no payment
for Annual Release Maintenance Fees are due pursuant to this Contract), Vendor
may terminate Owner's right to use the Software to which such fees apply. In no
event other than as set forth in this subsection 13.5 may Vendor terminate
Owner's right to use the Software. Notwithstanding any other provision of this
Contract, if there is a dispute, pending final resolution of such dispute, all
of Owner's rights under this Contract shall continue in full force and effect,
and Vendor will not terminate the RTU License, and so long as Owner continues to
pay Vendor applicable Annual Maintenance Release Fees, Vendor will not
terminate, suspend, interrupt or delay maintenance and support of the Software.

                13.6 Access to Source Codes. The Vendor represents and warrants
that as of the date hereof, Vendor has not established a Source Code escrow for
any of its existing customers. In the event that Vendor establishes a Source
Code escrow in the future which applies to any of the Software furnished to
Owner hereunder, Vendor shall add Owner as a beneficiary of such Source Code
escrow, and Owner shall be entitled to receive a copy of the escrowed Source
Code in the event of the occurrence of any of the events set out below. In
addition to the foregoing, the Vendor shall immediately deliver and hereby
grants the Owner a right to access the Source Code and to modify the Software
(the "RTM License") for the maintenance, enhancement and support of those
Products purchased from the Vendor and owned or operated by the Owner under the
following circumstances, provided that any such released Source Code shall be
subject to the confidentiality provisions set forth in this Contract:

                        (i) if the Vendor becomes insolvent, makes a general
        assignment for the benefit of creditors, files a voluntary petition in
        bankruptcy or an involuntary petition in bankruptcy is filed against the
        Vendor which is not dismissed within sixty (60) days, or suffers or
        permits the appointment of a receiver for its business, or its assets
        become subject to any proceeding under a bankruptcy or insolvency law,
        domestic or foreign, or has liquidated its business, or the Vendor, or a
        business unit of the Vendor that is responsible for maintenance of the
        Software, ceases doing business without providing for a successor, and
        the Owner has reasonable cause to believe that any such event shall
        cause the Vendor to be unable to meet its Warranty service or support
        requirements hereunder; or

                        (ii) if the Vendor ceases to maintain or support a
        previously supported version of the Software and Owner cannot obtain,
        with Vendor's assistance (for example, by providing a third party with
        Source Code or by any other appropriate method) the same support
        services the Vendor is required to provide under this Contract from
        another entity (either working with or independently from Vendor) at a
        price that is equal to or less than the prices for such support as
        provided herein, or there is a persistent and material failure by Vendor
        to provide the Warranty service or support it is required to provide
        pursuant to the terms of this Contract.

                13.7 Ownership of Intellectual Property. The Vendor shall own
all forms of intellectual property rights (including, but not limited to,
patent, trade secret, copyright and



                                       35
<PAGE>   36

mask rights) pertaining to the Software, and shall have the right to file for or
otherwise secure and protect such rights. The foregoing notwithstanding, the
parties understand and agree that from time to time the Owner may devise,
develop or otherwise create ideas or other concepts for services or new products
which are patentable or otherwise capable of receiving protection from
duplication. In such event, the Owner shall have the right to apply for a patent
in accordance with applicable law, provided, however, that notwithstanding this

intellectual property rights.

                SECTION 14. SOFTWARE AND EQUIPMENT CHANGES

                14.1 Software.

                14.1.1 Software Upgrades, Software Maintenance Releases,
Software Enhancements and Combined Releases. During the Contract Term, upon
payment of the Annual Release Maintenance Fees, calculated pursuant to Exhibit
B-5, Owner shall receive all base Software releases and all Software Maintenance
Releases, Software Upgrades, Software Enhancements and Software Combined
Releases applicable to Software for Products for which the Owner has obtained a
RTU License at such times as they become generally available to the Vendor's
customers. Owner shall also be entitled to receive Optional Software Features
upon payment of the appropriate fees determined in accordance with Exhibit B-5.
Owner may elect to purchase such features on a per feature basis, or purchase
annual buy-out rights on a per market basis, permitting Owner to select those
features it wishes to deploy in the relevant market.

                14.1.2 Notice. The Vendor shall give the Owner, or cause the
Owner to be given not less than ninety (90) days prior written notice of the
introduction of any Software Enhancement release or any Software Combined
Release or any optional Software release. In addition, in each February and
August of each year during the term of this Contract, the Vendor shall provide,
or cause to be provided, to the Owner a forecast of future Software Enhancement
releases, Software Upgrades, or Software Combined Releases or any optional
Software release, as the case may be, then currently being developed by or on
behalf of the Vendor.

                14.1.3 Installation, Testing and Maintenance. The installation
and testing of the Software by the Vendor and the acceptance thereof by the
Owner shall be performed in accordance with the criteria set forth in Exhibit G.

                14.1.4 Software Fixes. In the event that any Software
Maintenance Release, Software Upgrade, Software Enhancement or Software Combined
Release supplied by the Vendor during the term of this Contract has the effect
of preventing any System or any part thereof from satisfying, or performing in
accordance with the Specifications or the Exhibits or otherwise adversely
affects the functionality or features of any System or any part thereof, then
the Vendor shall promptly retrofit or take such other corrective action as may
be necessary to ensure that any System or any such affected part, as modified to
include each



                                       36
<PAGE>   37

such Software Maintenance Release, Software Upgrade, Software Enhancement or
Software Combined Release, shall satisfy, and perform in accordance with, the
Specifications and the Exhibits and restore all pre-existing functionality and
features as well as provide any new features and functionality provided by any
of the foregoing modifications, in each case without any charge to the Owner
(other than payment of the applicable fees pursuant to the terms of this
Contract). Notwithstanding anything contained herein in this subsection to the
contrary, Owner shall be responsible for the cost of any additional Equipment
required to accommodate additional capacity, memory or processing requirements
necessitated by any new Software feature or Optional Software Feature which
Owner elects to use (provided such use by Owner is optional without losing the
benefit of the Software Maintenance Release or Software Upgrade) which are
contained in any such Software Upgrade, Software Enhancement or Software
Combined Release; provided, however, that Owner shall not be required to pay for
any additional Equipment required to accommodate additional capacity, memory or
processing requirements necessitated by implementation of a required Software
Maintenance Release, whether or not such Software Maintenance Release is issued
as a stand-alone release, or is contained within a Software Upgrade, Software
Enhancement or Software Combined Release.

                14.2 Equipment.

                14.2.1 Equipment Upgrades. (a) Equipment Upgrades will be
provided to the Owner by the Vendor at no charge to the Owner as provided in
subsection 14.2.1(b) below. Equipment Enhancements must be provided to the Owner
by the Vendor, if requested by the Owner, and the Owner is obligated to make
payment therefor in an amount that is specified on the B Exhibits. If the Vendor
at any time issues an Equipment Upgrade which is combined with any Equipment
Enhancement (collectively, the "Equipment Combined Release") to such Equipment,
the Equipment Combined Release will be provided at no charge to the Owner unless
and until the Owner uses any of the Equipment Enhancements included within the
Equipment Combined Release, provided such use by Owner of such Equipment is
optional without losing the benefit of the Equipment Upgrade.

                (b) (i) After a Product has been shipped to the Owner, if the
Vendor issues an Equipment Upgrade or Equipment Enhancement, or where a
modification to correct an error in field documentation is to be introduced, the
Vendor will promptly notify the Owner of such change through the Vendor's design
change management system or another Vendor notification procedure. Each change
notification, whether or not it bears a restrictive legend, will be subject to
the confidentiality obligations provided in subsection 26.18, except that such
information may be reproduced by the Owner for the Owner's use as required
within the System. If the Vendor has engineered, furnished, and installed a
Product which is subject to an Equipment Upgrade, the Vendor will implement such
change, at its sole cost and expense, if it is announced within [*] for the 5
ESS switch and [*] for all other Products from the date of shipment of that
Product, and subject to the reasonable review and acceptance of the Owner at
such times as the Owner reasonably determines that it needs to review such
Vendor decision, by either (A) modifying the Product at the Owner's site; (B)
modifying the Product which the Owner has returned to the Vendor in accordance
with the Vendor's reasonable instructions pursuant to and in



                                       37

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.
<PAGE>   38

accordance with the terms of this Contract; or (C) replacing the Product
requiring the change with a replacement Product for which such change has
already been implemented. If the Vendor has not engineered the original Product
application and accordingly office records are not available to the Vendor, the
Vendor will provide the generic change information and associated parts for the
Owner's use in implementing such change.

                (ii) In any of the instances described in clause (i) above, if
the Vendor and the Owner agree that a Product or part thereof subject to such
change is readily returnable, without incurring any significant time or expense,
the Owner, at its expense, will remove and return such Product or part to the
Vendor's designated facility within the United States and the Vendor, at its
sole expense, will implement such change (or replace it with a Product or part
for which such change has already been implemented) at its facility and return
such changed (or replacement) Product or part at its sole cost and expense to
the Owner's designated location within the United States. Any such
reinstallation of Products which were readily returnable will be performed by
the Owner at its sole expense, provided such reinstallation can be done by Owner
without incurring any significant time or expense. In all other circumstances,
Vendor shall provide such removal, repair and reinstallation Services at its
sole cost and expense.

                (iii) If the Owner does not make or permit the Vendor to make an
Equipment Upgrade as stated above within the appropriate [*] or [*] period from
the date of change notification or such other period as the Vendor may agree,
subsequent changes, repairs or replacements affected by the failure to make such
change may, at the Vendor's option, be invoiced to the Owner whether or not such
subsequent change, repair or replacement is covered under the warranty provided
in this Contract for such Product. If requested by the Owner, Equipment Upgrades
announced more than the appropriate [*] or [*] period from the date of shipment
will be implemented at the Owner's expense.

                (iv) If the Vendor issues an Equipment Enhancement after a
Product has been shipped to the Owner, the Vendor will promptly notify the Owner
of such change if it is being offered to any of the Vendor's customers. Except
as otherwise set forth above in subsection 14.2(b), when an Equipment
Enhancement is requested by the Owner, the pricing set for such Equipment
Enhancements will be at the Vendor's standard charges subject to the applicable
discounts set forth in the B Exhibits.

                (v) All change notifications for Equipment Upgrades and
Equipment Enhancements provided by the Vendor to the Owner pursuant to the terms
of this Contract must contain the following information: (A) a detailed
description of the change; (B) the reason for the change; (C) the effective date
of the change; and (D) the implementation schedule for such change, if
appropriate.

                14.2.2 Notice. The Vendor shall give, or shall cause to be given
to, the Owner not less than ninety (90) days prior written notice of the
introduction of any Equipment Enhancement or any Equipment Combined Release. In
addition, in each February and August of each year during the Term of this
Contract, the Vendor shall



                                       38

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.
<PAGE>   39

provide the Owner with a forecast of future Equipment Enhancements to the
Equipment or Equipment Combined Releases then currently being developed by or on
behalf of the Vendor.

                14.2.3 Installation, Testing and Acceptance The Installation and
testing of the Equipment by the Vendor and the acceptance thereof by the Owner
shall be performed in accordance with the Exhibits and pursuant to the
Milestones contained in the Exhibits.

                14.2.4 Equipment Fixes. In the event that any Equipment Upgrade
or Equipment Enhancement, directly or indirectly, supplied by the Vendor during
the appropriate [*] or [*] period following the Effective Date or during [*]
period following the date of shipment of such Equipment Upgrade or Equipment
Enhancement, has the effect of preventing any System or any part thereof from
satisfying, or performing in accordance with, the Specifications or otherwise
adversely affects the functionality, interoperability or features of any System,
or any part thereof then the Vendor shall without any charge to the Owner
promptly retrofit or take such other corrective action as may be necessary to
assure that any System or any such affected part, as modified to include each
such Equipment Upgrade and Equipment Enhancement, shall satisfy, and perform in
accordance with, the Specifications and restore all pre-existing functionality
and features as well as provide any features and functionality provided by any
of the foregoing modifications.

                14.2.5 Equipment Backwards Compatibility Warranty. The Vendor
represents and warrants (the "Equipment Backwards Compatibility Warranty") that
each New Equipment Release will be Backwards Compatible, provided that it is
implemented within the specified time provided with each New Equipment Release.
[***] Notwithstanding the foregoing, the Equipment Backwards
Compatibility Warranty does not apply to Products developed beyond 3G1X which
are developed in accordance with standards not yet finalized as of the date
hereof.

                14.2.6 3G1X. [***]

                14.2.7 1.1 ASIC Product. The prices set forth in the B Exhibits
for a BTS and channel elements includes a BTS equipped with the hardware
component for Vendor's "1.1 ASIC Product". Each BTS furnished by Vendor
hereunder will, at no additional charge to Owner beyond the BTS prices set forth
in Exhibit B-1, be equipped

at the time of shipment, or be retrofitted to include after shipment, at
Vendor's sole expense, such hardware component of Vendor's 1.1 ASIC Product.

                14.3 Notice of Developments.

                14.3.1 Vendor Developments. The Vendor shall provide the Owner,
or cause to be provided to the Owner, through the Owner's chief executive
officer, with reasonable written notice of any Product developments, innovations
and/or technological advances (collectively "Vendor Developments") relevant to
the System simultaneous to giving such notice to any other customer or otherwise
making any such Vendor Development public; provided that the Vendor shall not be
obligated to provide the Owner such notice before any other customer if doing so
would breach any contractual obligation to any other customer, provided further
that any such notice need not include any information originated by another
customer of Vendor which is proprietary to such other customer of Vendor. For
the purposes of this subsection the term "Vendor" includes the Vendor and its
affiliates and subsidiaries.

                14.3.2 Participation in Testing. The Owner has the right, but
not the obligation, to witness and/or participate in any initial testing;
provided that any such initial testing of Vendor Developments shall be subject
to (i) scheduling as reasonably determined by the Vendor, (ii) the qualification
that the Owner's System meets the technical requirements for the testing of such
Vendor Development as reasonably determined by the Vendor (or otherwise that the
Owner is willing to update such System to meet such requirements), (iii) the
Owner's acknowledgment that it shall be able to provide the resources necessary
to implement the initial testing for such Vendor Development, and (iv) the Owner
and the Vendor executing a verification office testing agreement that identifies
the scope, terms, pricing, responsibilities and schedule related to the initial
testing of such Vendor Development. The Vendor shall provide the Owner at least
thirty (30) days' prior written notice of its intent to test any such Vendor
Development and upon the Owner's written request the Vendor shall allow the
Owner to participate in such testing upon terms and in a testing environment
reasonably acceptable to the parties at such time. Such rights shall not apply
to a Vendor Development originated by another customer of Vendor which includes
information which is proprietary to such other customer.

                14.3.3 Quarterly Notices. Vendor shall make reasonable efforts
to collect and distribute on a quarterly basis a list of new Software bugs,
problems, fixes, etc., provided that Vendor shall not be required to distribute
confidential information of any other customer.

                SECTION 15. INTELLECTUAL PROPERTY

                15.1 Intellectual Property. Neither Owner nor Vendor shall
publish or use any advertising, sales promotion, press releases or publicity
matters relating to this Contract without the prior written approval of the
other, in accordance with Section 26.13.



                                       40
<PAGE>   41

                15.2 Infringement. (a) The Vendor agrees that it shall defend,
indemnify and hold harmless, at its own expense, all suits and claims against
the Owner for infringement or violation of any patent, trademark, copyright,
trade secret or other intellectual property rights of any third party
enforceable in the United States or in any other territory where Vendor has
approved the deployment or use of Products under this Contract (collectively,
"Intellectual Property Rights"), covering, or alleged to cover, the Products or
any component thereof. The Vendor agrees that it shall pay all sums, including
without limitation, reasonable attorneys' fees and other costs incurred at
Vendor's written request or authorization, which, in defense of, by final
judgment or decree, or in settlement of any suit or claim to which the Vendor
agrees, may be assessed against, or incurred by, the Owner on account of such
infringement or violation, provided that the Owner shall cooperate in all
reasonable respects with the Vendor and its attorneys in the investigation,
trial and defense of such lawsuit or action and any appeal arising therefrom;
provided, however, that the Owner may, at its own cost, participate in the
investigation, trial and defense of such lawsuit or action and any appeal
arising therefrom. The parties shall cooperate with each other in any
notifications to insurers. If a claim for Losses (a "Claim") is to be made by a
party entitled to indemnification hereunder against the Vendor, the party
claiming such indemnification shall give written notice (a "Claim Notice") to
the Vendor as soon as practicable after the party entitled to indemnification
becomes aware of any fact, condition or event which may give rise to Losses for
which indemnification may be sought under this Agreement, provided, however, no
delay on the part of the Owner in notifying the Vendor shall relieve the Vendor
from any obligation hereunder unless (and then solely to the extent) the Vendor
is thereby materially prejudiced. If any lawsuit or enforcement action is filed
against any party entitled to the benefit of indemnity hereunder, written notice
thereof shall be given to the Vendor as promptly as practicable (and in any
event within fifteen (15) calendar days after the service of the citation or
summons). The Vendor shall be entitled, if it so elects, (i) to defend such
lawsuit or action, (ii) to employ and engage attorneys of its own choice to
handle and defend the same, at the Vendor's cost, risk and expense, and (iii) to
compromise or settle such Claim, which compromise or settlement shall be made
only with the written consent of the Owner (which may not be unreasonably
withheld), unless such compromise or settlement includes an unconditional
release of any claims against the Owner in which event such written consent of
the Owner shall not be required. If the Vendor fails to assume the defense of
such Claim within fifteen (15) calendar days after receipt of the Claim Notice,
the Owner against which such Claim has been asserted will (upon delivering
notice to such effect to the Vendor) have the right to undertake, at the
Vendor's cost and expense, the defense, compromise or settlement of such Claim
on behalf of and for the account and risk of the Vendor. In the event the Owner
assumes the defense of the Claim, the Owner will keep the Vendor reasonably
informed of the progress of any such defense, compromise or settlement. The
Vendor shall be liable for any settlement of any action effected pursuant to and
in accordance with this Agreement and for any final judgment (subject to any
right of appeal), and the Vendor agrees to indemnify and hold harmless the Owner
from and against any Losses by reason of such settlement or judgment.



                                       41
<PAGE>   42

                (b) The Vendor's obligation under this subsection shall not
extend to alleged infringements or violations that arise because the Products
provided by the Vendor are used in combination with other products furnished by
third parties and where any such combination was not installed, recommended or
approved by the Vendor.

                15.3 Vendor's Obligation to Cure. If in any such suit so
defended, all or any part of the Products or any component thereof is held to
constitute an infringement or violation of Intellectual Property Rights of
others and its use is enjoined, or if in respect of any claim of infringement or
violation the Vendor deems it advisable to do so, the Vendor shall at its sole
cost, expense and option take one or more of the following actions: (i) procure
the right to continue the use of the same without interruption for the Owner;
(ii) replace the same with non-infringing Products that meets the Specifications
in accordance with the terms of this Contract; or (iii) modify said Products,
any System or any component thereof so as to be non-infringing, provided that
the Products, any System or any component thereof as modified meets all of the
Specifications. In the event that the Vendor is not able to cure the
infringement pursuant to clause (i), (ii) or (iii) in the immediately preceding
sentence, in addition to the other rights and remedies provided in this Section
15, the Vendor shall refund to the Owner the full purchase price paid by the
Owner for such infringing Product or feature, and the Owner shall be under no
obligation to return to the Vendor such infringing Product or feature regardless
of whether, or by what means, the Owner, on its own or otherwise, subsequently
cures such infringement, unless Owner is directed to do so by court order.

                15.4 Vendor's Obligations. The Vendor's obligations under this
Section 15 shall not apply to any infringement or violation of Intellectual
Property Rights caused by unauthorized modification of the Products, any System
or any component thereof by the Owner, or arises from adherence to instructions
to apply Owner's trademark, trade name or other company identification to a
Product, or any infringement caused solely by the Owner's use and maintenance of
the Products other than in accordance with the Specifications, except as
authorized or permitted by the Vendor. The Owner shall indemnify the Vendor
against all liabilities and costs, including reasonable attorneys' fees, for
defense and settlement of any and all claims against the Vendor for
infringements or violations based upon this subsection.

                15.5 Liability of Vendor. The Liability of Vendor with respect
to any and all claims, actions, proceedings or suits by third parties alleging
infringement of patents, trademarks, or copyrights or violation of trade secrets
or proprietary rights because of, or in connection with, any items furnished
pursuant to this Contract shall be limited to the specific undertakings
contained in this Section 15.

                SECTION 16. DELAY

                16.1 Liquidated Damages. The parties agree that damages for
delay are difficult to calculate accurately and not reasonably determinable at
the time of execution of this Contract, and, therefore, agree that liquidated
damages (the "Liquidated Damages")



                                       42
<PAGE>   43

shall be paid for non-performance or late performance of the Vendor's
obligations to achieve a Guaranteed Substantial Completion Date for reasons not
otherwise excused by Force Majeure or Owner's failure to satisfy its obligations
set out in this Contact. The parties agree that Liquidated Damages are intended
to compensate Owner for the delayed or late performance by the Vendor and are
not a penalty.

                16.2 Delay and Default. In the event the Vendor fails to achieve
(other than as permitted by this Contract) the Substantial Completion of a
System on or before the Guaranteed Substantial Completion Date for such System
or during a ten day cure period following such date, the Vendor shall pay,
weekly in arrears, for the next [*] commencing on the eleventh day after the
Guaranteed Substantial Completion Date, Liquidated Damages to the Owner in an
amount equal to [*] (pro-rated on a daily basis for periods of time less than
one week) of the total amount of all Purchase Orders relating to the System with
respect to which the Vendor has so failed, based on the number of days elapsed
after a ten day cure period following the Guaranteed Substantial Completion Date
and before the achievement of Substantial Completion; provided that in the event
that Substantial Completion is not achieved prior to the expiration of such [*]
period, thereafter Vendor shall pay, weekly in arrears, additional Liquidated
Damages to the Owner in an amount equal to [*] (pro-rated on a daily basis for
periods of time less than one week) of the total amount of all Purchase Orders
relating to the System with respect to which the Vendor has so failed, based on
the number of days elapsed after the [*] plus ten day cure period
following the Guaranteed Substantial Completion Date and before the achievement
of Substantial Completion; provided that in no event shall the amount of
Liquidated Damages so paid in respect of a System exceed [*] of the total amount
of all Purchase Orders relating to the System with respect to which the Vendor
has so failed.

                16.3 System Capacity Guarantee. [***]

                16.4 Limitation. The foregoing provisions concerning Liquidated
Damages shall not be deemed to limit the amount payable by the Vendor to the
Owner for breach of contract, except for amounts payable on account of delay as
aforesaid, provided, however that the payment of Liquidated Damages shall be
Owner's sole remedy for the delay giving rise to the Vendor's obligation to pay
the Liquidated Damages.

                16.5 Early Completion Bonus. With respect to a System, Vendor
shall be entitled to an early completion bonus from the Owner in the event that
Substantial Completion with respect to such System occurs on or prior to the
date that is [*] prior to the Guaranteed Substantial Completion Date for such
System. Such early completion bonus shall be equal to [*] (pro-rated on a daily
basis for periods of time less than one week) of the total amount of all
Purchase Orders relating to such System, based on the number of days that
Substantial Completion occurs prior the date that is [*} prior to the
Guaranteed Substantial Completion Date for such System.

                SECTION 17. FORCE MAJEURE

                17.1 Excusable Delay. (a) If the performance of this Contract,
or of any obligation hereunder except for the obligations set forth in Section 5
is prevented, restricted or interfered with by reason of fires, breakdown of
plant, labor disputes, embargoes, government ordinances or requirements, civil
or military authorities, acts of God or of the public enemy, acts or omissions
of carriers, inability to obtain necessary materials or services from suppliers,
or other causes beyond the reasonable control of the party whose performance is
affected ("Force Majeure"), then the party affected, upon giving prompt notice
to the other party, shall be excused from such performance on a day-for-day
basis to the extent of such prevention, restriction, or interference (and the
other party shall likewise be excused from performance of its obligations on a
day-for-day basis to the extent such party's obligations relate to the
performance so prevented, restricted or interfered with); provided that the
party so affected shall use reasonable efforts to avoid or remove such cause of
non-performance and both parties shall proceed to perform their obligations with
dispatch whenever such causes are removed or cease.

                (b) The party claiming the benefit of excusable delay hereunder
shall (i)promptly notify the other party of the circumstances creating the
failure or delay and provide a statement of the impact of such party failure or
delay and (ii) use reasonable efforts to avoid or remove such causes of
nonperformance, excusable failure or delay. If an event of Force Majeure
prevents the Vendor from performing its obligations under this Contract for a
period exceeding sixty (60) days, the Owner may, upon prior written notice to
the other party, terminate this Contract.

                (c) In the event of a Force Majeure which the party claiming
relief for such event has used all best efforts to resolve in accordance with
the terms of this Contract, upon the written request of either party, the other
party shall in good faith negotiate modifications, to the extent reasonable and
necessary, in scheduling and performance criteria in order to reasonably address
the impact of such Force Majeure.

                SECTION 18. WARRANTIES

                18.1 Equipment and Services Warranty. Vendor warrants that, with
respect to each System, for a period of two (2) years from the date of
Substantial Completion, provided, however that if prior to Final Acceptance a
Major Outage occurs, the two (2) year period shall be extended by the number of
days elapsed between Substantial Completion and the date the Owner signs the
Certificate of Final Acceptance (as so determined, the "Warranty Period"), all
Equipment and Services furnished under this Contract with respect to such System
will be free of Defects and Deficiencies and shall conform to the applicable
portions of the Specifications (the "Equipment and Services Warranty"),
provided, however, that with respect to those Services for which a warranty is
set forth in an Exhibit, the warranty contained in the Exhibit shall supersede
the general Services warranty contained in this Section 18.1. With respect to
third-party manufactured Products which are not a part of a Core System, Vendor
shall furnish such Products only on a pass-through warranty basis;



                                       46



<PAGE>   47
provided, however, that Vendor shall identify such Products to Owner before
acceptance of any Purchase Order which includes any such Products. The terms of
the warranty applicable to such Products shall be provided in an addendum to the
Purchase Order. Except as noted in the B Exhibits, all Products referenced in
the B Exhibits qualify as Vendor-warranted Products. The Vendor's obligations
with respect to the Equipment and Services Warranty shall be to attempt first to
repair or replace at no additional cost, any defective Equipment or correct any
deficient Services. If, after using its best efforts to repair or replace such
Product and after consultation with and with the consent of Owner, which consent
shall not be unreasonably withheld, Vendor determines that it is unable to
repair, replace or otherwise correct such defect, Vendor shall provide a credit
or refund based on the original purchase price, and installation charges if
installed by Vendor. If, as a result of the Defect and Deficiency, the Product
fails to operate in accordance with the Specifications which causes the System
to fail to materially operate in accordance with its Specifications, a refund
shall be paid to the Owner on account of the purchase price for the total
System, less a pro-rata discount calculated with regard to the period of time
during the Warranty Period that Owner operated the System in In Revenue Service.
For purposes of calculating such pro rata discount, the period of time the Owner
would have been able to operate the System in In Revenue Service shall be ten
(10) years from Substantial Completion for the 5 ESS switch and seven years from
Substantial Completion for all other Products. In the event that Vendor pays a
refund hereunder, Owner shall return such Products to Vendor at Vendor's sole
cost and expense. The Warranty Period for all Equipment or Services repaired,
replaced or corrected under the Equipment and Services Warranty shall be the
longer of one (1) year from the date of delivery of the repaired or replacement
Equipment or from the completion of the corrected Services, as applicable, or
(ii) or the unexpired term of the Warranty Period. The Warranty Period for
Equipment purchased as spares shall be two (2) years from installation of such
Equipment.

        For those Products not readily returnable by Owner, or where Owner
cannot remove and reinstall the Products without incurring significant time and
expense, and where Vendor elects to repair or replace the Product, Vendor shall
repair or replace the Product at Owner's Site. In the event Vendor does the
repair work at Owner's site, Vendor shall be responsible for replacement of
cable and wire Products, and for reasonable Site restoration. If Vendor has
elected to repair or replace a defective Product, and the Product is readily
returnable by Owner without incurring significant work or expense, Owner is
responsible for removing and reinstalling the Products. Products returned for
repair or replacement will be accepted by Vendor only in accordance with its
instructions and procedures for such returns. The transportation expense
associated with returning such Product to Vendor shall be borne by Owner. Vendor
shall pay the cost of transportation of the repaired or replacing Product to the
return destination designated by Owner. Defective or nonconforming Products or
parts which are replaced hereunder shall become Vendor's property. Vendor may
use either the same or functionally equivalent new, remanufactured,
reconditioned or refurbished Products or parts in the furnishing of repairs or
replacements under this Contract, provided that such Products satisfy the
Specifications.

                18.2 Expansions Warranty. Vendor warrants that, with respect to
Products and Services constituting Expansions (including Expansions to a System,
or Expansions or



                                       47



<PAGE>   48

growth not part of a System, and all other purchased Products) furnished under
this Contract will be free of Defects and Deficiencies and shall conform the
applicable portions of the Specifications (the "Expansions Warranty"). The
warranty period with respect to such Products and Services shall be two (2)
years from the date of installation completion or completion of Services, as the
case may be (the "Expansions Warranty Period"). With respect to third-party
manufactured Products which are not a part of a Core System, Vendor shall
furnish such Products only on a pass-through warranty basis; provided, however,
that Vendor shall identify such Products to Owner before acceptance of any
Purchase Order which includes any such Products. The terms of the warranty
applicable to such Products shall be provided in an addendum to the Purchase
Order. Except as noted in the B Exhibits, all Products referenced in the B
Exhibits qualify as Vendor-warranted Products. The Vendor's obligations with
respect to the Expansions Warranty shall be to attempt first to repair or
replace at no additional cost, any defective Equipment or correct any deficient
Services. If, after using its best efforts to repair or replace such Product and
after consultation with and with the consent of Owner, which consent shall not
be unreasonably withheld, Vendor determines that it is unable to repair, replace
or otherwise correct such defect, Vendor shall provide a credit or refund based
on the original purchase price, and installation charges if installed by Vendor.
The warranty period for all Equipment or Services repaired, replaced or
corrected under the Expansions Warranty shall be the longer of one (1) year from
the date of delivery of the repaired or replacement Equipment or from the
completion of the corrected Services, as applicable, or (ii) or the unexpired
term of the Expansions Warranty Period. The Warranty Period for Equipment
purchased as spares shall be two (2) years from installation of such Equipment.

        For those Products not readily returnable by Owner, or where Owner
cannot remove and reinstall the Products without incurring significant time and
expense, and where Vendor elects to repair or replace the Product, Vendor shall
repair or replace the Product at Owner's Site. In the event Vendor does the
repair work at Owner's site, Vendor shall be responsible for replacement of
cable and wire Products, and for reasonable Site restoration. If Vendor has
elected to repair or replace a defective Product, and the Product is readily
returnable by Owner without incurring significant work or expense, Owner is
responsible for removing and reinstalling the Products. Products returned for
repair or replacement will be accepted by Vendor only in accordance with its
instructions and procedures for such returns. The transportation expense
associated with returning such Product to Vendor shall be borne by Owner. Vendor
shall pay the cost of transportation of the repaired or replacing Product to the
return destination designated by Owner. Defective or nonconforming Products or
parts which are replaced hereunder shall become Vendor's property. Vendor may
use either the same or functionally equivalent new, remanufactured,
reconditioned or refurbished Products or parts in the furnishing of repairs or
replacements under this Contract, provided that such Products satisfy the
Specifications.

                18.3 Software Warranty. Vendor warrants that, with respect to
each System for the Warranty Period, all Software will be free of Defects and
Deficiencies and shall conform to the applicable portions of the Specifications
(the "Software Warranty"). The Vendor's obligations with respect to the Software
Warranty shall be to attempt first to repair or replace at no additional cost,
any defective Software. If, after using its best efforts to



                                       48
<PAGE>   49

repair or replace such Software and after consultation with and with the consent
of Owner, which consent shall not be unreasonably withheld, Vendor determines
that it is unable to repair, replace or otherwise correct such defect, Vendor
shall provide a credit or refund based on the original purchase price, and
installation charges if installed by Vendor. If, as a result of the Defect and
Deficiency, the Software fails to operate in accordance with the Specifications
which causes the System to fail to materially operate in accordance with its
Specifications, a refund shall be paid to Owner on account of the purchase price
for the total System, less a pro rata discount calculated with regard to the
period of time during the Warranty Period that Owner operated the System in In
Revenue Service. For purposes of calculating such pro rata discount, the period
of time the Owner would have been able to operate the System in In Revenue
Service shall be ten (10) years from Substantial Completion for the 5 ESS switch
and seven years from Substantial Completion for all other Products. In the event
that Vendor pays a refund hereunder, Owner shall return such Products to Vendor.
The warranty period for all Software so corrected or replaced under the Software
Warranty shall be the longer of one (1) year from the date of delivery of the
repaired or replacement Software, or (ii) or the unexpired term of the Warranty
Period. Vendor shall be solely responsible for all costs and expenses incurred
by Owner or Vendor in connection with the de-installation, removal and
transportation of defective Software under the Software Warranty and for the
transportation and installation of repaired, corrected or replacement Software,
including without limitation any additional or upgraded Equipment or processing
capability necessary to run or operate such repaired, corrected or replacement
Software. The Warranty Period with respect to Software Maintenance Releases,
Software Upgrades, Software Enhancements and Software Combined Releases shall be
two (2) years from the successful installation of such Software Maintenance
Releases, Software Upgrades, Software Combined Releases and Software
Enhancements.

                18.4 [intentionally deleted]

                18.5 Year 2000 Warranty. Vendor warrants that, notwithstanding
any other warranty provided to Owner pursuant to this Contract, during the
period commencing on the date that the applicable Software Warranty Period
commences and ending on January 1, 2004, the Software will (a) process calendar
dates falling on or after January 1, 2000, with substantially the same
functionality as such Software processes calendar dates falling on or before
December 31, 1999, and (b) provide substantially the same functionality with
respect to the introduction of records containing dates falling on or after
January 1, 2000, as it provides with respect to the introduction of records
containing dates falling on or before December 31, 1999 (the "Year 2000
Warranty"). All of the foregoing functionality shall be known as "Year 2000
Capability". In the event Owner has or purchases more than one version of
Software, such versions of Software, if they are intended by Vendor to
interoperate, will be compatible and interoperate in such manner as to process
between them, as applicable, date related data correctly as described herein.
All of the foregoing functionality shall be known as "Year 2000
Interoperability". The foregoing sets forth an additional warranted
specification for Software developed by Vendor that Vendor has identified as
having Year 2000 Capability. The failure of such Software to meet such
specification during the Year 2000 Warranty Period shall, to the extent the
Software remains then subject to warranty protection, entitle Owner to the
remedies set out in this section.



                                       49
<PAGE>   50

Nothing in the foregoing shall be deemed to make Vendor responsible for the Year
2000 Capability or Year 2000 Interoperability of any third party software
interoperating or intended to interoperate with Software developed by Vendor.
Owner and or the manufacturer or other supplier of such third party software
shall be responsible for such compliance and assuring the ability of such
software to successfully operate while interoperating with Software developed by
Vendor.

                18.6 Warranty Claim Procedures. (a) If the Owner claims a breach
of any warranty, it shall notify the Vendor of the claimed breach within a
reasonable time after its determination that a breach has occurred. The Owner
shall allow the Vendor to inspect the Equipment, Software, Services, or the
System, as the case may be, on-site in order to effect the necessary repairs.

                (b) The Vendor shall respond to such warranty claims for
warranty Services in accordance with the procedures outlined in Exhibit N.

                18.7 Technical Assistance. The Vendor shall maintain a technical
assistance center and shall have technical support available to the Owner in
accordance with the requirements set forth in Exhibit N.

                18.8 Scope of Warranties. Unless otherwise stated herein, the
Warranties shall not apply to:

                18.8.1 defective conditions or nonconformities to the extent
        resulting from the following, if not consistent with applicable
        Specifications: unauthorized Owner modifications, misuse, neglect,
        accident, abuse, improper wiring, repairing, splicing, alteration,
        installation, storage or maintenance failure of Owner to apply
        previously applicable Vendor modifications or corrections;

                18.8.2 any Equipment, Services or Software damaged by accident
        or disaster, including without limitation, fire, flood, wind, water,
        lightning or power failure other than to the extent that any such
        Equipment, Services or Software should in accordance with the
        Specifications be able to withstand any such events; or

                18.8.3 non-integral items normally consumed in operation or
        which has a normal life inherently shorter than the Warranty Periods
        (e.g., fuses, lamps, magnetic tape); or

                18.8.4 damages or defects resulting directly from third party
        equipment, provided that this shall in no event limit the Vendor's
        obligations as to interoperability pursuant to the terms of this
        Contract;

                18.8.5 Equipment which have had their serial numbers or months
        and year of manufacture removed or obliterated by the Owner; or



                                       50
<PAGE>   51

                18.8.6 failures or deficiencies in BTS performance or System
        optimization resulting solely from changed environmental conditions or
        unauthorized changes to the System by Owner, or changes not consented to
        by Owner including, but not limited to, the growth of trees and other
        foliage, the erection of buildings, and interference from third party
        radio transmissions not otherwise engineered for by the Vendor;

except when any such damage or defects are made, done or caused by the Vendor or
any of its Subcontractors, their respective agents and employees.

                18.9 Third Party Warranties. If the Vendor purchases or
subcontracts for the manufacture of any part of a System or the performance of
any of the Services to be provided hereunder from a third party, the warranties
given to the Vendor by such third party shall inure, to the extent assigned to
the Owner pursuant to this Section 18 or permitted by law, to the benefit of the
Owner, and the Owner shall have the right, at its sole discretion, to enforce
such warranties directly and/or through the Vendor. The warranties of such third
parties shall be in addition to and shall not, unless otherwise expressly stated
herein, be in lieu of any warranties given by the Vendor under this Contract.

                18.10 Additional Sites. In the event that under the remedy
provisions of this Section 18 the Vendor is required to provide additional MSC
and/or BTS's requiring additional Sites, the Owner shall be responsible for all
Site Acquisition.

                18.11 EXCLUSIVE REMEDIES. THE FOREGOING EQUIPMENT, SERVICES,
SOFTWARE AND EXPANSIONS WARRANTIES AND REMEDIES ARE EXCLUSIVE FOR THE PURPOSES
OF ANY BREACH BY THE VENDOR OF ANY SUCH WARRANTY AND ARE IN LIEU OF ALL OTHER
EXPRESS AND IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

                SECTION 19. INSURANCE

                19.1 Insurance. The Vendor shall maintain insurance in

in connection with, or based on allegations of, any of the following:



                                       51
<PAGE>   52

                (a)     Vendor's failure to observe or perform any duties or
                        obligations to Subcontractors or any third parties
                        within the reasonable contemplation of this Contract;

                (b)     the death or bodily injury of any agent, employee,
                        customer, business invitee or any other person caused by
                        the tortious conduct (including without limitation
                        negligence, willful misconduct or breach of warranty) or
                        strict liability of Vendor, any Subcontractor or its or
                        their respective employees, contractors, agents or
                        representatives;

                (c)     the damage, loss or destruction of any real or tangible
                        personal property caused by the tortious conduct
                        (including without limitation negligence, willful
                        misconduct or breach of warranty) or strict liability of
                        Vendor, any Subcontractor or its or their respective
                        employees, contractors, agents or representatives; or

                (d)     any claim, demand, charge, action, cause of action or
                        other proceeding asserted against Owner but arising out
                        of or resulting from an act or omission of Vendor, any
                        Subcontractor or its or their respective employees,
                        contractors, agents or representatives in its or their
                        respective capacities as an employer.

                20.2 Claim for Losses. If a Claim is to be made by a party
entitled to indemnification hereunder against the Vendor, the party claiming
such indemnification shall give a Claim Notice to the Vendor as soon as
practicable after the party entitled to indemnification becomes aware of any
fact, condition or event which may give rise to Losses for which indemnification
may be sought under this Agreement, provided, however, no delay on the part of
the Owner in notifying the Vendor shall relieve the Vendor from any obligation
hereunder unless (and then solely to the extent) the Vendor is thereby
materially prejudiced. If any lawsuit or enforcement action is filed against any
party entitled to the benefit of indemnity hereunder, written notice thereof
shall be given to the Vendor as promptly as practicable (and in any event within
fifteen (15) calendar days after the service of the citation or summons). The
Vendor shall be entitled, if it so elects, (i) to defend such lawsuit or action,
(ii) to employ and engage attorneys of its own choice to handle and defend the
same, at the Vendor's cost, risk and expense, and (iii) to compromise or settle
such Claim, which compromise or settlement shall be made only with the written
consent of the Owner (which may not be unreasonably withheld), unless such
compromise or settlement includes an unconditional release of any claims against
the Owner in which event such written consent of the Owner shall not be
required. If the Vendor fails to assume the defense of such Claim within fifteen
(15) calendar days after receipt of the Claim Notice, the Owner against which
such Claim has been asserted will (upon delivering notice to such effect to the
Vendor) have the right to undertake, at the Vendor's cost and expense, the
defense, compromise or settlement of such Claim on behalf of and for the account
and risk of the Vendor. In the event the Owner assumes the defense of the Claim,
the Owner will keep the Vendor reasonably informed of the



                                       52
<PAGE>   53

progress of any such defense, compromise or settlement. The Vendor shall be
liable for any settlement of any action effected pursuant to and in accordance
with this Agreement and for any final judgment (subject to any right of appeal),
and the Vendor agrees to indemnify and hold harmless the Owner from and against
any Losses by reason of such settlement or judgment.

                20.3 Limitation On Liability. THE ENTIRE LIABILITY OF VENDOR FOR
ANY CLAIM, LOSS, DAMAGE OR EXPENSE OF OWNER OR ANY OTHER ENTITY ARISING OUT OF
THIS CONTRACT, OR THE USE OR PERFORMANCE OF ANY PRODUCT OR SERVICE, WHETHER IN
AN ACTION FOR OR ARISING OUT OF BREACH OF CONTRACT OR TORT, INCLUDING
NEGLIGENCE, INDEMNITY OR STRICT LIABILITY, SHALL BE EXPRESSLY SET FORTH HEREIN

                AGGREGATE AMOUNTS OF ALL PURCHASE ORDERS WITH RESPECT TO ALL
                SYSTEMS, PROVIDED THAT FOR PURPOSES OF QUANTIFYING THE DAMAGES
                FOR A FAILURE TO SATISFY THE CAPACITY GUARANTEE, THE ADDITIONAL
                EQUIPMENT FURNISHED BY THE VENDOR AT NO CHARGE TO THE OWNER
                SHALL BE VALUED AT THE PURCHASE PRICES FOR SUCH EQUIPMENT SET
                FORTH IN THIS CONTRACT AND, AS SO VALUED, SHALL BE DEEMED TO BE

                23.1 Dispute Resolution. In the event any controversy, claim,
dispute, difference or misunderstanding between the Owner and the Vendor arises
out of or relates to this Contract, any term or condition hereof, any of the
Work to be performed hereunder or in connection herewith, each party shall
designate managers to meet and negotiate in good faith in an attempt to amicably
resolve such controversy, claim, dispute, difference or misunderstanding in
writing. Such managers shall meet for this purpose within ten (10) Business
Days, or such other time period mutually agreed to by the parties, after written
notice from either party. If the parties are unable to resolve the controversy,
claim, dispute, difference or misunderstanding through good faith negotiations
within ten (10) Business Days after such meeting or meetings, each party shall,
within five (5) Business Days after the expiration of such ten (10) Business Day
period, prepare a written position statement which summarizes the unresolved
issues and such party's proposed resolution. Such position statement shall be
delivered by the Vendor to the Owner's Chief Executive Officer and by the Owner
to the Vendor's corresponding officer or representative for resolution within
(5) Business Days, or such other time period mutually agreed to by the parties.

                23.2 Tolling. All applicable statutes of limitation shall be
tolled to the extent permitted by Applicable Law while the dispute resolution
procedures specified in this Section are pending, and nothing herein shall be
deemed to bar any party from taking such action as the party may reasonably deem
to be required to effectuate such tolling.

                SECTION 24. TERMINATION AND EVENTS OF DEFAULT

                24.1 Termination Without Cause. The Owner may, at its sole
option, terminate this Contract, in its entirety, for convenience upon ninety
(90) days' prior written notice at any time. Any Purchase Orders issued prior to
any such termination above shall remain in effect and shall be fulfilled to the
extent that such orders are outstanding as of the date of such termination. In
the event that at the time of such termination the aggregate amount of all
Purchase Orders delivered to Vendor under this Contract (the "Aggregate Purchase
Orders") is less than One Hundred Million Dollars ($100,000,000), Owner shall
pay to the Vendor the lesser of (i) the difference between One Hundred Million
Dollars ($100,000,000) and the Aggregate Purchase Orders; or (ii) the aggregate
amounts of the Products and Services furnished by Vendor pursuant to Exhibits
B-2 and B-3 prior to the date of such termination.

                24.2 Termination for Cause. The Owner shall have the right to
terminate this Contract in its entirety (except as otherwise set forth in clause
(g) below) without any penalty or payment obligation, except as provided in
subsection 24.5 below, upon the occurrence of any of the events of default (each
a "Vendor Event of Default") as set forth below:

                (a) the Vendor (i) files a voluntary petition in bankruptcy or
        has an involuntary petition in bankruptcy filed against it that is not
        dismissed within sixty



                                       56
<PAGE>   57

        (60) days of such involuntary filing, (ii) admits the material
        allegations of any petition in bankruptcy filed against it, (iii) is
        adjudged bankrupt, (iv) is unable generally to pay its debts as they
        mature, (v) makes a general assignment for the benefit of its creditors,
        or if a receiver is appointed for all or a substantial portion of its
        assets and is not discharged within sixty (60) days after his
        appointment, or (vi) the Vendor commences any proceeding for relief from
        its creditors in any court under any state insolvency statutes; or

                (b) the Vendor disregards or violates any Applicable Laws or
        Applicable Permits which has a material adverse effect on the business,
        financial condition or operations of Owner or on any of its Systems
        ("Material Adverse Effect"); or

                (c) the Vendor allows material Defects and Deficiencies to
        exist; or

                (d) the Vendor fails to fulfill its obligations with respect to
        the satisfaction, discharge or bonding of liens as set forth herein; or

                (e) the Vendor abandons or ceases for a period in excess of
        thirty (30) days its performance of the Work (except as a result of
        Force Majeure or a casualty which is fully covered by insurance or as to
        which other provisions reasonably acceptable to the Owner are being
        diligently pursued); or

                (f) the Vendor assigns or subcontracts Work other than as
        provided for in this Contract which has a Material Adverse Effect; or

                (g) the Vendor misses the Guaranteed Substantial Completion Date
        for any given System by a period in excess of one hundred-fifty (150)
        days; provided that in such case the Owner shall have the right, but not
        the obligation, to terminate this Contract with respect to only that
        System in which such delay occurred; and provided further that such
        failure to achieve such date was not caused by (i) a Force Majeure event
        and/or (ii) any act or omission of the Owner; or

                (h) if an event of Force Majeure prevents the Vendor from
        performing its obligations under this Contract for a period exceeding
        sixty (60) days, the Owner may, upon prior written notice to the Vendor,
        terminate this Contract in accordance with the Force Majeure provisions
        above; or

                (i) the Vendor otherwise materially breaches any provision of
        this Contract.

                24.3 Remedies. (a) If any of the Vendor Events of Default
exists, the Owner may, in addition to and without prejudice to any other rights
or remedies of the Owner in this Contract or at law or in equity, terminate this
Contract upon written notice to the Vendor; provided, however, that the Owner
shall have first provided to the Vendor the following periods of notice and
opportunity to cure:



                                       57
<PAGE>   58

                        (i) in the case of a Vendor Event of Default specified
        in the foregoing clauses (a) or (b), no notice or opportunity to cure
        shall be required from the Owner; and

                        (ii) in the case of any other Vendor Event of Default,
        the Owner shall have provided thirty (30) days' prior written notice,
        and the Vendor shall have failed (i) to commence to cure the default
        within five (5) Business Days of delivery of such notice, and (ii) to
        diligently pursue such cure and remedy the breach entirely.

                (b) If the Owner elects to terminate this Contract, the Owner
may, in addition to and without prejudice to any other rights or remedies of the
Owner in this Contract or of law or in equity, do one or more of the following:

                        (i) require Vendor, at no additional charge to Owner, to
        complete or assist others with the completion of all ordered but
        unfinished Work, including the sharing with Owner and others all
        relevant engineering and design data, procurement data, manufacturing
        data, construction and erection data, start-up and testing data,
        materials, and Products that shall become part of such unfinished System
        and/or the specified Systems, which Vendor would otherwise have been
        required to deliver to Owner pursuant to the terms of this Contract but
        for the breach, under reasonably appropriate non-disclosure agreements;
        or

                        (ii) direct that the Vendor assign its Subcontractor
        agreements to the Owner without any change of price or conditions
        therein or penalty or payment therefor.

                (c) In the event of any termination of this Contract by Owner in
connection with a Vendor Event of Default, Owner shall have no liability for any
failure to satisfy the Minimum Purchase Commitment prior to such termination.

                24.4 Discontinuance of Work. Upon such notification of
termination, the Vendor shall immediately discontinue all of the Work (unless
such notice of termination directs otherwise), and, as more fully set forth in
subsection 24.3(b), deliver to the Owner copies of all data, drawings,
specifications, reports, estimates, summaries, and such other information, and
materials as may have been accumulated by the Vendor in performing the Work,
whether completed or in process, which Vendor would otherwise have been required
to deliver to Owner pursuant to this Contract but for the breach. Furthermore,
the Vendor shall assign, assemble and deliver to the Owner all purchase orders
and Subcontractor agreements requested by the Owner.

                24.5 Payments. If the Owner terminates this Contract pursuant to
subsection 24.2, the Vendor shall not be entitled to receive further payment
other than payments due and payable under this Contract and not subject to
dispute prior to such termination (provided that any such disputed amounts shall
be paid by the Owner when and if such dispute is in fact resolved).
Notwithstanding anything herein to the contrary, the Owner may withhold
payments, if any, to the Vendor for the purposes of offset of amounts



                                       58
<PAGE>   59

owed to the Owner pursuant to the terms of this Contract until such time as the
exact amount of damages due the Owner from the Vendor is fully determined by a
court of competent jurisdiction.

                24.6 Continuing Obligations. Termination of this Contract for
any reason (i) shall not relieve either party of its obligations with respect to
the confidentiality of the Proprietary Information as set forth in subsection
26.18, (ii) shall not relieve either party of any obligation which applies to it
and which expressly or by implication survives termination, and (iii) except as
otherwise provided in any provision of this Contract expressly limiting the
liability of either party, shall not relieve either party of any obligations or
liabilities for loss or damage to the other party arising out of or caused by
acts or omissions of such party prior to the effectiveness of such termination
or arising out of its obligations as to portions of the Work already performed
or of obligations assumed by the Vendor prior to the date of such termination.

                24.7 Vendor's Right to Terminate. The Vendor shall have the
option to terminate this Contract without any penalty or payment obligations,
other than undisputed payment obligations outstanding as of the date of any such
termination pursuant to the terms of this Contract if:

                (a) the Owner (i) files a voluntary petition in bankruptcy or
        has an involuntary petition in bankruptcy filed against it that is not
        dismissed within sixty (60) days of such involuntary filing, (ii) admits
        the material allegations of any petition in bankruptcy filed against it,
        (iii) is adjudged bankrupt, (iv) makes a general assignment for the
        benefit of its creditors, or if a receiver is appointed for all or a
        substantial portion of its assets and is not discharged within sixty
        (60) days after his appointment, or (v) commences any proceeding for
        relief from its creditors in any court under any state insolvency
        statutes, and any such filing, proceeding, adjudication or assignment as
        described herein above shall otherwise materially impair the Owner's
        ability to perform its obligations under this Contract; or

                (b) the Owner fails to make payments of undisputed amounts due
        to the Vendor pursuant to the terms of this Contract which are more than
        sixty (60) days overdue, provided that such failure has continued for at
        least thirty (30) days after the Vendor has notified the Owner of its
        right and intent to so terminate on account of such overdue amount; and
        provided, further, that such failure to make undisputed payments to
        Vendor shall not arise out of or relate to a termination of or credit
        restrictions under the Vendor Financing, or

                (c) the Owner materially breaches any provision of this Contract
        other than a breach to which Section 24.7(b) is applicable, and after
        the Vendor having provided thirty (30) days' prior written notice, the
        Owner shall have failed (i) to commence to cure the default within five
        (5) Business Days of delivery of such notice, and (ii) to diligently
        pursue such cure and remedy the breach entirely.

                24.8 Special Termination Events. (a) Neither the Vendor nor the
Owner shall be obligated to perform under this Contract, except as specifically
provided, in the event that financing for the purpose of acquiring any System
sufficient to cover Owner's current payment obligations hereunder has not been
finalized with the Vendor on terms and conditions reasonably satisfactory to the
Owner. Unless acceptable financing is available, either party may terminate this
Contract without recourse, except as noted below, by notifying the other party
in writing. Further, the parties agree that the delivery and performance
schedules shall be extended by the period of time required to secure acceptable
financing. In the event of a termination of this Contract pursuant to this
subsection the Owner shall remain liable for amounts due to the Vendor for all
Work performed or Products delivered by the Vendor or any of its Subcontractors
pursuant to the specific terms of this Contract which had been directly
delivered to or performed for the Owner and/or any of its facilities or Sites in
accordance with the terms of this Contract. Any amounts owed by the Owner for
Work done or Products delivered by the Vendor during such interim period not
otherwise invoiced to the Owner by the Vendor prior to the termination of such
interim period, shall be invoiced to the Owner by the Vendor within thirty (30)
days. In no event shall the Owner be liable to the Vendor due to a termination
of this Contract pursuant to this subsection for satisfaction of the Minimum
Purchase Commitment or for any of the Vendor's direct or indirect costs or
expenses incurred in connection with any supplies or equipment ordered by the
Vendor or agreements entered into by the Vendor in order to enable it to fulfill
its obligations hereunder or in connection with the establishment of and/or
upgrade to its manufacturing, personnel, engineering, administrative or other
capacities and/or resources in contemplation of or pursuant to its performance
in accordance with the terms of this Contract and any amounts due to the Vendor
pursuant to this subsection shall be limited in all cases to Work actually done
or Products or Services actually delivered to the Owner, its Sites or its
facilities.

                (b) If at any time after the Effective Date any material change
shall have occurred in any Applicable Law or in the interpretation thereof by
any Governmental Entity, or there shall be rendered any decision in any judicial
or administrative case or proceeding, in either case which, in the reasonable
opinion of the Owner would make the Owner's use of any part of any System
illegal or would subject the Owner or any of its Affiliates to any material
penalty, other material liability or onerous condition or to any burdensome
regulation by any Governmental Entity or otherwise render the use of such System
economically nonviable, then, with respect to such System, or affected part
thereof, or with respect to all Systems if so affected, the Owner may terminate
this Contract without charge or penalty of any kind; provided that (i) the Owner
gives the Vendor prior written notice of any such change or decision and (ii)
that the Owner uses its reasonable efforts for a reasonable time to reverse or
ameliorate such change or decision to the extent possible or practical prior to
declaring such termination. In the event of a termination pursuant to this
subsection, payment obligations incurred by the Owner for Work actually done or
Products or Services actually delivered by the Vendor prior to such termination
pursuant to this Contract shall be payable by the Owner to the Vendor on the
same terms and subject to the limitations set forth in subsection 24.8(a) above.

                SECTION 25. SUSPENSION

                25.1 Owner's Right to Suspend Work. The Owner may at any time
issue a Change Order to the Vendor to suspend all or any part of the Work for
such period of time as the Owner may reasonably determine to be appropriate. Any
such Change Order shall be handled in accordance with the provisions of Section
11 hereof.

                SECTION 26. MISCELLANEOUS

                26.1 Amendments. The terms and conditions of this Contract may
only be amended by mutually agreed contract amendments. Each amendment shall be
in writing and shall identify the provisions to be changed and the changes to be
made. Contract amendments shall be signed by duly authorized representatives of
each of the Vendor and the Owner.

                26.2 Owner Liabilities. Vendor understands and agrees that no
third party shall guarantee or otherwise be in any way liable with respect to
any obligations or liabilities of the Owner or any of its affiliates pursuant to
this Contract.

                26.3 Offset. The Vendor hereby waives any right of offset of
amounts owed by the Owner to the Vendor pursuant to the terms of this Contract.

                26.4 Assignment. The Owner may assign this Contract, or any part
hereof, to any affiliate of Owner without the Vendor's approval or consent.
Subject to the foregoing and except as otherwise permitted herein, neither this
Contract nor any portion hereof may be assigned by either party without the
express prior written consent of the other party. The Owner may, without the
consent of the Vendor, collaterally assign its rights hereunder (including, but
not limited to, all licenses with respect to the Software) to any or all parties
providing financing for any part of a System for the benefit of the Vendor and
one or more other entities providing financing for any part of a System or
similar arrangement for the benefit of the Vendor and one or more other entities
providing for the financing for any part of a System, in either case, which
arrangement, as the case may be, is reasonably acceptable to the Vendor in
accordance with the terms of the financing documents. If requested by the Owner,
the Vendor shall within seven (7) calendar days of such request provide a
written consent to any such assignment; provided that such consent shall permit
reassignment if the financing parties exercise their remedies under the
documents for such financing subject to reasonable standards as to (i) the
creditworthiness of the assignee and (ii) the fact that the assignee is not at
such time a direct competitor of the Vendor involved in the manufacture of
communications equipment, software or related services. The foregoing rights and
obligations are in addition to those set forth elsewhere in this Contract. Any
attempted assignment in violation of the terms of this Contract shall be null
and void. Subject to the foregoing, this Contract shall bind and inure to the
benefit of the parties to this Contract, their successors and permitted assigns.

agrees not to assert, by way of motion, as a defense or otherwise, in any such
action, any claim that it is not subject personally to the jurisdiction of the

                26.12 Waiver. Unless otherwise specifically provided by the

                                       63

trademark or service mark of the other party or its affiliates is mentioned; and
neither party shall publish or use such advertising without the other party's

obtaining of prior written approval for each such use pursuant to this
subsection may be an administrative burden. At the request of either party, the
Owner and the Vendor shall establish mutually acceptable guidelines for the uses
specified therein. Such guidelines shall be subject to change from time to time
at the reasonable request of either party.

                26.14 Records and Communications. Procedures for keeping and

                26.16 Financing Requirements. The Vendor acknowledges that the
attainment of financing for construction of the System may be subject to
conditions that are customary and appropriate for the providers of such
financing. Therefore, the Vendor agrees to promptly consider any reasonable
amendment to or modification or assignment of this Contract required by such
providers (including, without limitation, any pertinent industrial development
authority or other similar governmental agency issuing bonds for financing of
the System) which do not materially modify the scope of the Vendor's Work in
order to obtain such financing. In the event that any such amendment or
modification materially increases the Vendor's risk or costs hereunder, the
Owner and the Vendor shall negotiate in good faith to adjust pricing matters,
and to equitably adjust such other provisions of this Contract, if any, which
may be affected thereby, to the extent necessary to reflect such increased risk
or costs. In no event shall the Vendor be required to accept any modification or
amendment pursuant to this subsection provide it has a commercially reasonable
basis for such refusal.

                26.17 Owner Review, Comment and Approval. To the extent that
various provisions of this Contract provide for the Owner's review, comment,
inspection, evaluation, recommendation or approval, the Owner may at its option
do so in conjunction and/or consultation with the Vendor. To the extent that
this Contract requires the Owner to submit, furnish, provide or deliver to the
Vendor any report, notice, Change Order, request or other items, the Owner may
at its option and upon written notice to the Vendor designate a representative
to submit, furnish, provide or deliver such items as the Owner's agent therefor.
To the extent that various provisions of this Contract provide that the Owner
may order, direct or make requests with respect to performance of the Work or is
provided access to the System sites or any other site, the Owner may at its
option and upon written notice to the Vendor authorize a representative to act
as the Owner's agent therefor. Upon receipt of such notice, the Vendor shall be
entitled to rely upon such authorization until a superseding written notice from
the Owner is received by the Vendor.

                26.18 Confidentiality. (a) All information which is identified
as proprietary or confidential by the disclosing party, including without
limitation all oral and written information (including, but not limited to,
determinations or reports by arbitrators pursuant to the terms of this
Contract), disclosed to the other party is deemed to be confidential, restricted
and proprietary to the disclosing party (hereinafter referred to as "Proprietary
Information"). Each party agrees to use the Proprietary Information received
from the other party only for the purpose of this Contract. Except as specified
in this Contract, no other rights, and particularly licenses, to trademarks,
inventions, copyrights, patents, or any other intellectual property rights are
implied or granted under this Contract or by the conveying of Proprietary
Information between the parties. Proprietary Information supplied is not to be
reproduced in any form except as required to accomplish the intent of, and in
accordance with the terms of, this Contract. The receiving party shall provide
the same care to avoid disclosure or unauthorized use of Proprietary Information
as it provides to protect its own similar proprietary information but in no
event shall the receiving party fail to use reasonable care under the
circumstances to avoid disclosure or unauthorized use of Proprietary
Information. All Proprietary Information shall be retained by the receiving
party in a secure place with access limited to only such of the receiving
party's employees,



                                       65
<PAGE>   66

subcontractors or agents who need to know such information for purposes of this
Contract and to such third parties as the disclosing party has consented to by
prior written approval. All Proprietary Information, unless otherwise specified
in writing (i) remains the property of the disclosing party, (ii) shall be used
by the receiving party only for the purpose for which it was intended, and (iii)
such Proprietary Information, including all copies of such information, shall be
returned to the disclosing party or destroyed after the receiving party's need
for it has expired or upon request of the disclosing party, and, in any event,
upon termination of this Contract. At the request of the disclosing party, the
receiving party shall furnish a certificate of an officer of the receiving party
certifying that Proprietary Information not returned to disclosing party has
been destroyed. For the purposes hereof, Proprietary Information does not
include information which:

                (i)     is published or is otherwise in the public domain
                        through no fault of the receiving party at the time of
                        any claimed disclosure or unauthorized use by the
                        receiving party;

                (ii)    prior to disclosure pursuant to this Contract is
                        properly within the legitimate possession of the
                        receiving party as evidenced by reasonable documentation
                        to the extent applicable;

                (iii)   subsequent to disclosure pursuant to this Contract is
                        lawfully received from a third party having rights in
                        the information without restriction of the third party's
                        right to disseminate the information and without notice
                        of any restriction against its further disclosure;

                (iv)    is independently developed by the receiving party or is
                        otherwise received through parties who have not had,
                        either directly or indirectly, access to or knowledge of
                        such Proprietary Information;

                (v)     is transmitted to the receiving party after the
                        disclosing party has received written notice from the
                        receiving party after termination or expiration of this
                        Contract that it does not desire to receive further
                        Proprietary Information;

                (vi)    is obligated to be produced under order of a court of
                        competent jurisdiction or other similar requirement of a
                        Governmental Entity, so long as the party required to
                        disclose the information provides the other party with
                        prior notice of such order or requirement and its
                        cooperation to the extent reasonable in preserving its
                        confidentiality; or

                (vii)   the disclosing party agrees in writing is free of such
                        restrictions.

                (b) Because damages may be difficult to ascertain, the parties
agree, without limiting any other rights and remedies specified herein, an
injunction may be sought against the party who has breached or threatened to
breach this subsection. Each party represents and warrants that it has the right
to disclose all Proprietary Information which it has



                                       66
<PAGE>   67

disclosed to the other party pursuant to this Contract, and each party agrees to
indemnify and hold harmless the other from all claims by a third party related
to the wrongful disclosure of such third party's proprietary information.

                26.19 Entirety of Contract; No Oral Change. This Contract and
the Exhibits and Schedules referenced herein constitute the entire contract
between the parties with respect to the subject matter hereof, and supersede all
proposals, oral or written, all previous negotiations, and all other
communications between the parties with respect to the subject matter hereof. No
modifications, alterations or waivers of any provisions herein contained shall
be binding on the parties hereto unless evidenced in writing signed by duly
authorized representatives of both parties as set forth in this Contract.

                26.20 Relationship of the Parties. Nothing in this Contract
shall be deemed to constitute either party a partner, agent or legal
representative of the other party, or to create any fiduciary relationship
between the parties. The Vendor is and shall remain an independent contractor in
the performance of this Contract, maintaining complete control of its personnel,
workers, Subcontractors and operations required for performance of the Work.
This Contract shall not be construed to create any relationship, contractual or
otherwise, between the Owner and any Subcontractor, except to establish Owner as
a third party beneficiary of the Vendor's contacts with Subcontractors as
provided herein.

                26.21 Discretion. Notwithstanding anything contained herein to
the contrary, to the extent that various provisions of this Contract call for an
exercise of discretion in making decisions or granting approvals or consents,
the parties shall be required to exercise such discretion, decision or approvals
and in good faith.

                26.22 Non-Recourse. No past, present or future limited or
general partner in or of the Owner, no parent or other affiliate of any company
comprising the Owner, and no officer, employee, servant, executive, director,
agent or authorized representative of any of them (each, an "Operative") shall
be liable by virtue of the direct or indirect ownership interest of such
Operative in the Owner for payments due under this Contract or for the
performance of any obligation, or breach of any representation or warranty made
by the Owner hereunder. The sole recourse of the Vendor for satisfaction of the
obligations of the Owner under this Contract shall be against the Owner and the
Owner's assets and not against any Operative or any assets or property of any
such Operative. In the event that a default occurs in connection with such
obligations, no action shall be brought against any such Operative by virtue of
its direct or indirect ownership interest in the Owner.

                26.23 Improvements, Inventions and Innovations. All rights in
any improvements, inventions, and innovations made solely by the Owner shall
vest in the Owner, and the Owner and its affiliates shall have the right to
exploit such improvements, inventions, and innovations. All rights in any
improvements, inventions and innovations made solely by the Vendor shall vest in
the Vendor, and the Vendor and its affiliates shall have the right to exploit
such improvements, inventions and innovations. All rights in any improvements,
inventions and innovations made by the substantial contribution of both parties
("Joint Information") shall vest jointly in both parties. Joint Information does
not



                                       67
<PAGE>   68

include any underlying information owned by one of the parties prior to
commencement of such joint activities or developed beyond the scope of such
joint activities, including Products and Product information, technical
information or inventions developed prior to the commencement of any joint
activities, developed outside of the scope of such joint activities or developed
solely by either party. The rights of joint ownership to such Joint Information
shall be rights of full non-exclusive worldwide ownership, including rights to
license and transfer. Each party may exploit its rights to the Joint Information
independent of the other and may retain all economic benefits thereof, neither
party shall have any obligation to account to the other for profits derived from
the Joint Information and each party shall have full rights to enforce the Joint
Information intellectual property rights against non-authorized users.

                26.24 Attachments and Incorporations. All Schedules and Exhibits
attached hereto, are hereby incorporated by reference herein and made a part of
this Contract with the same force and effect as though set forth in their
entirety herein.

                26.25 Conflicts. In the event of any conflict or inconsistency
among the provisions of this Contract and the documents attached hereto and
incorporated herein, such conflict or inconsistency shall be resolved by giving
precedence to this Contract and thereafter to the Exhibits, Schedules and
Specifications.

                26.26 References to Certain Sources. Reference to standard
specifications, manuals or codes of any technical society, organization or
association or to the laws or regulations of any Governmental Entity, whether
such reference is specific or by implication, by this Contract, means the latest
standard specification, manual, code, laws or regulations in effect at the time
of such reference, except as may be otherwise specifically agreed to by the
Owner. However, no provision of any reference, standard, specification, manual
or code (whether or not specifically incorporated by reference in this Contract)
shall be effective to change the duties and responsibilities of the Owner or the
Vendor from those set forth in this Contract; provided that nothing contained in
this Contract shall require the Owner or the Vendor to violate then existing and
enforceable Applicable Laws.

                26.27 Counterparts. This Contract may be executed by one or more
of the parties to this Contract on any number of separate counterparts, and all
of said counterparts taken together shall be deemed to constitute one and the
same instrument.

                26.28 Cooperation. Vendor acknowledges that Owner may have one
or more third party vendors, contractors and other personnel engaged to provide
work, equipment or services to Owner in connection with or related to this
Contract. Vendor agrees to reasonably communicate and cooperate with such third
parties at all times and, at the request of Owner, coordinate Vendor's and
Vendor's Subcontractors' activities hereunder with the activities of such third
parties.

                26.29 Survival. Notwithstanding any expiration or termination of
this Contract, the provisions of Sections 2.8, 12, 13, 14, 15, 18, 20 and 26.18
shall continue in full force and effect.

BTS & MSC INSTALLATION

I. STATEMENT OF WORK

         1. GENERAL

         The purpose of this section is to describe Owner's and Vendor's
         responsibilities for the ordering, scheduling, transport, warehousing,
         testing, delivery, installation and acceptance of BTS and or MSC
         equipment at one or more sites secured by Owner as part of its RF
         Network design for a market. In no case should this document supersede
         the terms and conditions of the base contract. Both parties shall use
         best efforts to individually and jointly complete activities identified
         in the following narrative and matrices to accomplish the installation
         of all BTS' and associated materials to insure the timely and efficient
         operation of the Owner's network.

         2. RESPONSIBILITIES

            b. Owner

               (1). Prior to install - Owner shall, using a "just-in-time"
               delivery philosophy, issue purchase orders for BTS' and MSC' and
               related equipment to the Vendor. Owner shall provide Vendor a
               copy of the Network Design for review by Vendor and incorporation
               into the production design of equipment for the individual site.
               Owner shall insure through separate contracts that all local
               permits and approvals have been secured for the installation of
               Vendor's equipment at a cell site. All Owner provided antennas,
               jumper and coax shall be installed and swept prior to or at the
               time of BTS' equipment installation. All Owner installed power,
               grounding and air conditioning shall be installed prior to or
               contemporaneous with the time of MSC/OEM equipment installation
               to meet Vendor's written specifications. Power and telco shall
               have been ordered and either installed or scheduled for
               installation at the site. A ground ring and bar shall be provided
               to meet Vendor's written specifications. Access and staging areas
               shall be secured for use by Vendor to carry out their
               responsibilities.

               (2). During install - Owner shall make available technical staff
               to monitor installation, review and conduct such operational
               tests as may be agreed upon by Owner and Vendor as part of this
               installation activity. Owner shall make available, as required,
               subcontractors to carry out such modifications to the
               positioning, placement or replacement of antennas, positioning,
               placement or replacement of existing equipment, cables, coaxial
               cable and power distribution systems as may be required by Seller



<PAGE>   84

               to carry out the installation and optimization of their equipment

                               PRODUCT DESCRIPTION

                                  INTRODUCTION

The AutoPACE TM System provides performance management and some aspects of
configuration management for Lucent Technologies wireless systems. This software
tool can be used for monitoring and maintaining or improving system performance,
troubleshooting, capacity planning, and, in general, engineering a Lucent
Technologies wireless system to provide peak quality of service. New releases of
the AutoPACE System are issued approximately twice a year to support new ECP and
cell site software releases and to provide new features and capabilities. The
current release is AutoPACE 13.01.

GENERAL BACKGROUND

The AutoPACE System is a second generation tool that has evolved over more than
10 years. Strongly driven by user input, it was developed to enhance and replace
the performance analysis software package introduced in 1987 in response to an
assessment of the needs of AUTOPLEX System operators.

Performance analysis is required to monitor and maintain (or improve) the
quality of service once a system is operational. Performance analysis can
indicate aspects of a system that are not operating at acceptable levels due
either to design deficiencies, hardware/software failures, or the growth of the
system and/or subscriber base.

              AUTOPACE SYSTEM FUNCTIONAL CAPABILITIES: AN OVERVIEW

The AutoPACE System provides capabilities in the following functional
categories:

CONFIGURATION MANAGEMENT

AutoPACE System Configuration Management provides reports and analyses of the
translatable parameters that define the configuration of a Lucent Technologies
wireless system. Reports include both pre-defined geographic displays and
pre-defined tabular reports. Also, the AutoPACE System User Definable Report
(UDR) tool allows users to define their own reports of system configuration
parameters. An associated utility can compare configuration parameters at two
different points in time and display the differences. Currently, AutoPACE cannot
be used to modify the configuration of a system.

The AutoPACE database stores the most recent view. of the system configuration
and this is refreshed with a frequency defined by the user (typically once per
day). Configuration Management can report on more than one system as well as
systems with more than one MSC.

TRAFFIC ANALYSIS

AutoPACE System Traffic Analysis can be used for hourly, daily, or longer-term
analyses, including weekly, monthly, or annual reports, limited only by the
amount of data stored by the user. Traffic and performance data for cell sites,
trunks, logical and physical antenna faces, IS-41 inter-system networking and
MSC elements are collected, analyzed, and displayed as user-defined tabular
reports and graphs. Traffic Analysis can report every count provided by the
AUTOPLEX Service Measurement sub-system and the domestic 5ESS Switch DCS.
Virtually all Traffic Analysis reports are user-defined(4). The elements of a
report definition include several aspects, including: the system elements
included in a report, the counts included in a report, the data and time scope
of the report, the details of the presentation of the counts (including busy
hour analysis and data summarization details), and the organization, destination
and appearance of the output.

Traffic data, collected from the OMP as well as the domestic 5ESS Switch DCS on
an hourly basis, can be stored in the AutoPACE database for a period of time
determined by the user-provided storage capacity of the AutoPACE server. Traffic
Analysis can report on more than one system as well as systems with more than
one MSC.

MAINTENANCE MESSAGE ANALYSIS

AutoPACE System Maintenance Message Analysis is used to study Call Processing
Failure (CPF) messages that are generated by the AUTOPLEX System when a call
terminates abnormally. Pre-defined and user-defined reports based on Call
Processing Failure messages can

        performance metrics recommended by Lucent Technologies and several
        reports that support capacity planning trending recommend by Lucent
        Technologies.

<PAGE>   93

be used to troubleshoot performance problems associated with cell site hardware,
specific mobile units, or terminals associated with a given power class, access
technology, or manufacturer. Maintenance Message Analysis also reports the
frequency with which the various types of Call Processing Failure messages
occur. These counts can be reported directly by the Maintenance Message Analysis
module and can also be included in the Traffic Analysis reports described above.

Call Processing Failure messages are collected in hourly files on the OMP and
transferred to the AutoPACE server where they are loaded into the AutoPACE
database. AutoPACE Maintenance Message Analysis can report on more than one
system as well as systems with more than one MSC.

SPECIAL ENGINEERING STUDIES

AutoPACE System Special Engineering Studies (SES) support four types of
scheduled engineering studies:

        -       Power Level Measurements (PLM) to analyze RF signal and
                impairment measurements

        -       Voice Channel Selection Activity (VCSA) to report the details of
                voice channel selection decisions

        -       Handoff Matrix (HOM) to report the flow of calls between handoff
                neighbors

        -       RF Call Trace to analyze the signal strengths and digital error
                rates received by a test terminal as a function of time

These studies are described in more detail below.

Note that the SES studies themselves are included as standard software in the
MSC and cell generic software and are not part of AutoPACE. However, the
AutoPACE System provides an easy and reliable interface to schedule any of the
SES studies and, after they have executed, AutoPACE can collect the data to
analyze and report it in formats that support troubleshooting.

                        AUTOPACE SYSTEM GENERAL FEATURES

The following sections describe several general features that significantly
enhance the functional capabilities of the AutoPACE System

USER INTERFACE

Many of the benefits of the AutoPACE System are realized at the Graphical User
Interface (GUI). The AutoPACE System provides a GUI to improve the efficiency,
effectiveness, and overall user-friendliness of its performance analysis
capabilities. The AutoPACE System is a Microsoft Windows application; as such it
shares the ease of use of other Windows applications. Users already familiar
with Windows applications will quickly relate to the AutoPACE System interface.

The AutoPACE System is designed to allow traffic engineers and technicians to
use any of the available capabilities with a minimum of special training.
AutoPACE System reports can be specified to run according to a user-defined
schedule. Moreover, the output is available as either tabular or graphical
reports that can be selected or redefined with just a few keystrokes or clicks
of the mouse. Map reports, which display configuration data based on geography,
provide added insight into the performance of a wireless system. Finally,
On-Line Help is available for efficient and easy access to reliable, up-to-date
information without interrupting the workflow.

AUTOMATION

The AutoPACE System allows a user to specify schedules for automatically
collecting traffic data from one or more AUTOPLEX Systems. Additionally, the
AutoPACE System provides the ability to automate the generation of user-defined
reports. A user can specify when to run a report (for example, on a daily or
other regular basis or as a one time case), which report(s) are to be run, and
the output destination.

SPREADSHEET COMPATIBILITY

The AutoPACE System uses the Microsoft Excel spreadsheet program internally to
output reports (except for map reports). A User Defined Macro capability
provides all the flexibility and power of the spreadsheet to enhance the
analysis of the data. In addition, the AutoPACE System can load data directly
into Microsoft Excel. Thus the use of Excel allows a high degree of
customization and automation by the user, providing additional flexibility for
AutoPACE System users to display high-resolution color plots of primary traffic
data or secondary values calculated from them. For example, the user is able to
choose the axis variable in a plot to study traffic-related dependencies within
a system. Plots can be bar charts, pie charts, line graphs, or any of the other
standard Excel reporting formats.

AUTOPACE SYSTEM DATABASE

January 1999
<PAGE>   95
All data in the AutoPACE System are stored in a relational database, implemented
using INFORMIX(R)(5) database software. The AutoPACE System database supports
three types of data:

        -       AUTOPLEX System Call Processing Failure Messages.

                The database contains Call Processing Failure Messages collected
                from AUTOPLEX System for use by AutoPACE System Maintenance
                Message Analysis and reporting capabilities. The database also
                supports the generation of counts that summarize the contents of
                those messages.

        -       AUTOPLEX System Configuration Parameters.

                The AutoPACE System database contains a copy of configuration
                parameters for the AUTOPLEX System, taken from the MSC
                Application Database(6) as well as user-supplied data such as
                geographic information or network element names.

        -       AUTOPLEX System Service Measurements.

                The AutoPACE System database contains service measurements
                collected from AUTOPLEX System and 5ESS Switch DCSs for use by
                AutoPACE System traffic analysis and reporting capabilities.
                Moreover, the database supports the generation of a variety of
                summary data.

The AutoPACE System automatically accesses its database for all applications.
However, to meet special needs, users can directly access the AutoPACE databases
using the appropriate INFORMIX database tools.(7)

Note that the Special Engineering Studies data, used exclusively for
troubleshooting, are not archived in the AutoPACE database.

                          AUTOPACE SYSTEM CONFIGURATION

ARCHITECTURE

The AutoPACE System incorporates a client-server architecture. The clients do
not contain databases and must access data from a server. A single server is
able to access one or more AUTOPLEX Systems via TCP/IP connections and to
support one or more clients, connected to the server by a local area network
(LAN(8)). This configuration allows multiple AutoPACE System clients to share a
common database. As a result, data are available to all users without wasteful
duplication and without the possibility of inconsistent data. The AutoPACE
System server provides additional capabilities that significantly enhance the
effectiveness and utility of the AutoPACE System, including:

        -       automatic scheduled data collection

        -       database management for data storage and administration

        -       high speed data access via the LAN.

Data can be stored for any length of time required by the user, limited only by
the amount of user-provided disk storage capacity.

AUTOPACE SYSTEM HARDWARE/SOFTWARE PLATFORM

The AutoPACE System client, implemented on a PC as a Microsoft Windows product,
is positioned take advantage of technical innovations in the personal
computing/workstation market. The AutoPACE System server is provided on UNIX
System V Release 4 (Solaris(9)) running on a SUN SPARCStation.

AUTOPACE SYSTEM SWITCH INTERFACE

The AutoPACE System is designed to be used only with Lucent Technologies
wireless systems. An AutoPACE System client interfaces with an AutoPACE System
server over a LAN. The AutoPACE System server, in turn, interfaces with one or
more systems, either through a dial-up WAN or dedicated data lines into a port
on the Operations and Management Platform (OMP).(10)

- ----------

(8)     While not strictly required, a LAN will provide the best performance.
        High bandwidth data connections support remote access of the server by a
        client.

(9)     The currently supported Solaris release numbers can be obtained from
        your Lucent Technologies wireless account representative.

(10)    Note that the AutoPACE System is not sold as a turnkey product. The
        hard-are required to support the tool as well as third party vendor
        software (e.g., INFORNUX) must be provided by the customer. However, the
        Lucent Technologies Customer Technical Support Organization will provide
        support to help identify the specific hardware, software, configuration,
        and capacity required for a particular installation.

2.      SYSTEM DESCRIPTION

The AUTOPLEX system is comprised of a diverse network of processors required to
support a wireless switching system. Figure 2.0-1 shows the major components
that comprise the AUTOPLEX system architecture. Figure 2.0-1 does not show all
the AUTOPLEX Network Elements and interfaces. More detailed diagrams may be
found later in the document.

                                    [graphic]

                    FIGURE 2.0-1 AUTOPLEX SYSTEM ARCHITECTURE

The AUTOPLEX system is designed with a high degree of redundancy to provide
reliable services to wireless subscribers. The AUTOPLEX Network Elements are
each designed with a redundancy scheme that is best suited to the service that
they provide. The following subsections defines the role of each of the AUTOPLEX
Network Element and its associated redundancy strategy.

2.1     OPERATIONS AND MANAGEMENT PLATFORM (OMP)

The OMP is an adjunct processor connected to the ECP via a redundant pair of
high speed data links. The OMP is not actively involved in processing wireless
calls. The OMP hosts a wide range of OA&M applications including:

        -  collecting and storing service measurement data to support
           Performance Management,

        -  collecting special study data to support Performance Management,

        -  providing a forms based front end for the ECP Recent Change/Verify
           (RC/V) application for Configuration Management,

        -  maintaining log files for AUTOPLEX event reports,

        -  supporting a near real time billing interface for Accounting
           Management,

        -  storing cell site inventory data for Configuration Management, and

        -  storing backup software images for the AP and the Flexent cell
           products.

The multi-window OMP client terminals (attached to the OMP's Ethernet) provide
access to the OA&M applications for maintaining all Network Elements in the
AUTOPLEX system (ECPC, cell sites and 5ESS-2000 DCS). See section 4.2 for more
details.

The OMP is built on a scalable Sun computing platform. It utilizes UNIX System V
Release 4 (Solaris(R)(1)) and supports open systems networking standards. The
OMP acts as an interface point into the service provider's Wide Area Network
(WAN) for network operations. Operations Support Systems (OSSs) can connect to
the OMP to support network level Fault Management, Performance Management,
Configuration Management, and Accounting Management. See Section 4.3 for more
details on AUTOPLEX interfaces to the OSSs.

2.2     AUTOPACE(R)

The AutoPACE system is an adjunct set of processors (the AutoPACE server, and
multiple AutoPACE client PCs) that monitor and report AUTOPLEX performance data.
The AutoPACE system is designed to be used only with the AUTOPLEX system. Figure
2.6-1 below shows a typical AutoPACE configuration. The AutoPACE server receives
performance data from the OMP and stores it in a data base. The AutoPACE client
PCs execute AutoPACE applications with support from the AutoPACE server.

         (b) Unless the Administrative Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender's share of such
Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with paragraph (a) of this Section
and may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. In such event, if a Lender has not in fact made its share
of the applicable Borrowing available to the Administrative Agent, then the
applicable Lender and the Borrower severally agree to pay to the Administrative
Agent forthwith on demand such corresponding amount with interest thereon, for
each day from and including the date such amount is made available to the
Borrower to but excluding the date of payment to the Administrative Agent, at
(i) in the case of such Lender, the greater of the Federal Funds Effective Rate
and a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation or (ii) in the case of the Borrower,
the interest rate applicable to ABR Loans. If such Lender pays such amount to
the Administrative Agent, then such amount shall constitute such Lender's Loan
included in such Borrowing.

         SECTION 2.05. Interest Elections. (a) Each Borrowing initially shall be
of the Type specified in the applicable Borrowing Request and, in the case of a
LIBOR Borrowing, shall have an initial Interest Period as specified in such
Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing
to a different Type or to continue such Borrowing and, in the case of a LIBOR
Borrowing, may elect Interest Periods therefor, all as provided in this Section.
The Borrower may elect different options with respect to different portions of
the affected Borrowing, in which case each such portion shall be allocated
ratably among the Lenders holding the Loans comprising such Borrowing, and the
Loans comprising each such portion shall be considered a separate Borrowing.

         (b) To make an election pursuant to this Section, the Borrower shall
notify the Administrative Agent of such election by telephone by the time that a
Borrowing Request would be required under Section 2.03 if the Borrower were
requesting a Borrowing of the Type resulting from such election to be made on
the effective date of such election. Each such telephonic Interest Election
Request shall be irrevocable and shall be confirmed promptly by hand delivery


<PAGE>   47
                                                                              41


or telecopy to the Administrative Agent of a written Interest Election Request
in a form approved by the Administrative Agent and signed by the Borrower.

         (c) Each telephonic and written Interest Election Request shall specify
the following information in compliance with Section 2.02:

                  (i) the Borrowing to which such Interest Election Request
         applies and, if different options are being elected with respect to
         different portions thereof, the portions thereof to be allocated to
         each resulting Borrowing (in which case the information to be specified
         pursuant to clauses (iii) and (iv) below shall be specified for each
         resulting Borrowing);

                  (ii) the effective date of the election made pursuant to such
         Interest Election Request, which shall be a Business Day;

                  (iii) whether the resulting Borrowing is to be a LIBOR
         Borrowing or an ABR Borrowing; and

                  (iv) if the resulting Borrowing is a LIBOR Borrowing, the
         Interest Period to be applicable thereto after giving effect to such
         election, which shall be a period contemplated by the definition of the
         term "Interest Period".

If any such Interest Election Request requests a LIBOR Borrowing but does not
specify an Interest Period, then the Borrower shall be deemed to have selected
an Interest Period of one month's duration.

         (d) Promptly following receipt of an Interest Election Request, the
Administrative Agent shall advise each Lender of the details thereof and of such
Lender's portion of each resulting Borrowing.

         (e) If the Borrower fails to deliver a timely Interest Election Request
with respect to a LIBOR Borrowing prior to the end of the Interest Period
applicable thereto, then, unless such Borrowing is repaid as provided herein, at
the end of such Interest Period such Borrowing shall be converted to an ABR
Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default
has occurred and is continuing and the Administrative Agent, at the request of
the Required Lenders, so notifies the Borrower, then, so


<PAGE>   48
                                                                              42



long as an Event of Default is continuing (i) no outstanding Borrowing may be
converted to or continued as a LIBOR Borrowing and (ii) unless repaid, each
LIBOR Borrowing shall be converted to an ABR Borrowing at the end of the
Interest Period applicable thereto.

         SECTION 2.06. Termination and Reduction of Commitments. (a) Unless
previously terminated, the Commitments shall terminate on the earlier of (i) the
Availability Termination Date and (ii) the date of termination of the Purchase
Agreement.

         (b) On the date of each Loan made by any Lender such Lender's
Commitment shall be reduced by an amount equal to such Loan.

         (c) In the event that a prepayment of Loans would be required pursuant
to paragraph (b), (c) or (d) of Section 2.09, all Commitments then in effect
shall be reduced ratably by an aggregate amount equal to the excess, if any, of
the amount of the required prepayment over the aggregate principal amount of
Loans outstanding immediately prior to giving effect to such prepayment.

         (d) The Borrower may at any time terminate, or from time to time
reduce, the Commitments; provided that each reduction of the Commitments
pursuant to this paragraph (d) shall be in an amount that is an integral
multiple of $1,000,000 and not less than $5,000,000.

         (e) The Borrower shall notify the Administrative Agent of any election
to terminate or reduce the Commitments under paragraph (d) of this Section at
least three Business Days prior to the effective date of such termination or
reduction, specifying such election and the effective date thereof. Promptly
following receipt of any such notice, the Administrative Agent shall advise the
Lenders of the contents thereof. Each notice delivered by the Borrower pursuant
to this Section shall be irrevocable. Any termination or reduction of the
Commitments shall be permanent. Each reduction of the Commitments pursuant to
paragraph (d) of this Section shall be made ratably among the Lenders in
accordance with their respective Commitments (including any Contingent
Commitments), except that the Borrower may elect, prior to the Full Availability
Date, to terminate or reduce Contingent Commitments without terminating or
reducing other Commitments.

         SECTION 2.07. Repayment of Loans; Evidence of Debt. (a) The Borrower
hereby unconditionally promises to pay to the Administrative Agent for the
account of each Lender the then unpaid principal amount of each Loan of such
Lender as provided in Section 2.08.

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

         (c) The Administrative Agent shall maintain accounts in which it shall
record (i) the amount of each Loan made hereunder, the Class and Type thereof
and the 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) the amount of any sum received by the Administrative
Agent hereunder for the account of the Lenders and each Lender's share thereof.

         (d) The entries made in the accounts maintained pursuant to paragraph
(b) or (c) of this Section shall be prima facie evidence of the existence and
amounts of the obligations recorded therein; provided that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
the Loans in accordance with the terms of this Agreement.

         (e) Any Lender may request that Loans of any Class made by it be
evidenced by a promissory note. In such event, the Borrower shall prepare,
execute and deliver to such Lender a promissory note payable to the order of
such Lender (or, if requested by such Lender, to such Lender and its registered
assigns) and in a form approved by the Administrative Agent. Thereafter, the
Loans evidenced by such promissory note and interest thereon shall at all times
(including after assignment pursuant to Section 9.04) be represented by one or
more promissory notes in such form payable to the order of the payee named
therein (or, if such promissory note is a registered note, to such payee and its
registered assigns).

         SECTION 2.08. Amortization of Loans. (a) Subject to adjustment pursuant
to paragraph (c) of this Section, the Borrower shall repay Borrowings on each
Payment Date set forth below in an aggregate amount equal to the percentage set
forth opposite such Payment Date multiplied by an amount equal to the sum of all
Loans made during the Availability Period (whether or not previously repaid):

Each of thirteenth, fourteenth, fifteenth and sixteenth                      6.25%

Each of seventeenth, eighteenth, nineteenth and twentieth                    8.75%

         (b) To the extent not previously paid, all Loans shall be due and
payable on the Maturity Date.

         (c) Any prepayment of a Borrowing shall be applied to reduce the
subsequent scheduled repayments of the Borrowings to be made pursuant to this
Section in the inverse order of maturity thereof.

         (d) Prior to any repayment of any Borrowings hereunder, the Borrower
shall select the Borrowing or Borrowings to be repaid and shall notify the
Administrative Agent by telephone (confirmed by telecopy) of such selection not
later than 2:00 p.m., New York City time, three Business Days before the
scheduled date of such repayment; provided that the Borrower shall select
Borrowings to be repaid such that each Lender shall receive its pro rata share
of such repayment as provided in Section 2.16. Each repayment of a Borrowing
shall be applied ratably to the Loans included in the repaid Borrowing.
Repayments of Borrowings shall be accompanied by the payment of accrued interest
on the amount thereof.

                                                                              45


         SECTION 2.09. Prepayment of Loans. (a) The Borrower shall have the
right at any time and from time to time to prepay any Borrowing in whole or in
part, subject to the requirements of this Section.

         (b) Subject to paragraph (h) of this Section, in the event and on each
occasion that any Net Proceeds are received by or on behalf of the Borrower or
any Subsidiary Loan Party in respect of any Prepayment Event, the Borrower
shall, within three Business Days after such Net Proceeds are received, prepay
Borrowings in an aggregate principal amount equal to such Net Proceeds; provided
that, in the case of any event described in clause (a) of the definition of the
term Prepayment Event, if the Borrower shall deliver to the Administrative Agent
a certificate of a Financial Officer to the effect that the Borrower and the
Subsidiaries intend to apply the Net Proceeds from such event (or a portion
thereof specified in such certificate), within 180 days after receipt of such
Net Proceeds, to acquire real property, equipment or other tangible assets to be
used in the business of the Borrower and the Subsidiaries, and certifying that
no Default has occurred and is continuing, then no prepayment shall be required
pursuant to this paragraph in respect of the Net Proceeds in respect of such
event (or the portion of such Net Proceeds specified in such certificate, if
applicable) except to the extent of any such Net Proceeds therefrom that have
not been so applied by the end of such 180-day period, at which time a
prepayment shall be required in an amount equal to such Net Proceeds that have
not been so applied.

         (c) Subject to paragraph (h) of this Section, following the end of each
fiscal year of the Borrower, commencing with the fiscal year during which the
Availability Termination Date occurs, the Borrower shall prepay Borrowings in an
aggregate principal amount equal to 50% of Excess Cash Flow for such fiscal
year. Each prepayment pursuant to this paragraph shall be made on or before the
date on which financial statements are delivered pursuant to Section 5.01 with
respect to the fiscal year for which Excess Cash Flow is being calculated (and
in any event within 90 days after the end of such fiscal year).

         (d) In the event and on each occasion that the Borrower or any
Subsidiary Loan Party Repays any Indebtedness of the Borrower or any Subsidiary
Loan Party then the Borrower shall, within three Business Days after the date of


<PAGE>   52
                                                                              46


such Repayment, prepay Borrowings in an aggregate amount equal to the product of
(x) the sum of the aggregate principal amount of the Loans outstanding at the
time, multiplied by (y) a fraction, the numerator of which is the aggregate
principal amount of such Repayment, and the denominator of which is the amount
of Total Indebtedness immediately prior to such Repayment (excluding
Indebtedness in respect of the Loans and Indebtedness outstanding under
revolving credit facilities); provided that prepayments of Borrowings shall not
be required pursuant to this paragraph in respect of (i) Repayments of Loans,
(ii) any Repayment of Indebtedness to the extent such Repayment is refinanced by
incurring other Indebtedness that (A) has a scheduled maturity date that is on
or after the scheduled maturity date of the Indebtedness being refinanced, (B)
has a weighted average life to maturity that is equal to or longer than the
remaining weighted average life to maturity of the Indebtedness being
refinanced, determined immediately prior to giving effect to such Repayment, (C)
does not include any provisions that may require mandatory Repayment thereof
prior to scheduled maturity, other than scheduled repayments taken into
consideration in determining compliance with clause (B) above and other
provisions that are not materially more burdensome than any such provisions
included in the Indebtedness being refinanced, (D) is issued or incurred by the
same Person that issued or incurred the Indebtedness being refinanced and is not
Guaranteed or secured by any Lien unless the Indebtedness being refinanced was
Guaranteed or secured (in which case such Indebtedness shall not be Guaranteed
by any Person that did not Guarantee the Indebtedness being refinanced and shall
not be secured by a Lien on any asset that did not secure the Indebtedness being
refinanced), and (E) is subordinated to the Obligations on terms no less
favorable than the terms on which the Indebtedness being refinanced was so
subordinated, if such refinanced Indebtedness was so subordinated, (iii) any
Repayment of Indebtedness outstanding under a revolving credit facility to the
extent that (A) the commitments of the lenders to make loans thereunder remain
in effect after giving effect to such Repayment or are replaced by commitments
under a replacement revolving credit facility and (B) such commitments are not
reduced within six months thereafter, (iv) any Repayment of secured Indebtedness
in connection with the sale of the assets securing such Indebtedness, (v) any
Repayment of Indebtedness at the scheduled final maturity thereof or in
accordance with regularly scheduled amortization requirements prior to maturity
or (vi) any Repayment of other Eligible Secured

Debt that constitutes a mandatory prepayment thereof in respect of a Prepayment
Event or Excess Cash Flow, to the extent that the Lenders receive a pro rata
prepayment in respect of such event pursuant to paragraph (b) or (c) of this
Section.

         (f) Prior to any optional or mandatory prepayment of Borrowings
hereunder, the Borrower shall select the Borrowing or Borrowings to be prepaid
and shall specify such selection in the notice of such prepayment pursuant to
paragraph (g) of this Section; provided that the Borrower shall select
Borrowings to be prepaid such that each Lender shall receive its pro rata share
of such prepayment as provided in Section 2.16.

         (g) The Borrower shall notify the Administrative Agent by telephone
(confirmed by telecopy) of any prepayment hereunder not later than 11:00 a.m.,
New York City time, three Business Days before the date of prepayment. Each such
notice shall be irrevocable and shall specify the prepayment date, the principal
amount of each Borrowing or portion thereof to be prepaid and, in the case of a
mandatory prepayment, a reasonably detailed calculation of the amount of such
prepayment. Promptly following receipt of any such notice, the Administrative
Agent shall advise the Lenders of the contents thereof. Each partial prepayment
of any Borrowing shall be in an amount that would be permitted in the case of an
advance of a Borrowing of the same Type as provided in Section 2.02, except as
necessary to apply fully the required amount of a mandatory prepayment. Each
prepayment of a Borrowing shall be applied ratably to the Loans included in the
prepaid Borrowing. Prepayments of Borrowings shall be accompanied by the payment
of accrued interest on the amount prepaid.

         (h) If any other Eligible Secured Debt is outstanding at the time that
any mandatory prepayment of Borrowings is required to be made pursuant to
paragraph (b) or (c) of this Section, then, to the extent that the terms of any
such other Eligible Secured Debt require that a mandatory prepayment be made of
such other Eligible Secured Debt pursuant to corresponding provisions applicable
thereto, the aggregate principal amount of such prepayment required to be made
hereunder shall be reduced by the aggregate principal amount of such
corresponding prepayments required to be made in respect of other Eligible
Secured Debt; provided that, in any event, each mandatory prepayment of
Borrowings required to be made pursuant to paragraph (b) or (c) of this Section
shall be in an aggregate principal


<PAGE>   54
                                                                              48


amount not less than (i) the aggregate principal amount of Borrowings that would
be required to be prepaid if no other Eligible Secured Debt was outstanding at
the time, multiplied by (ii) a fraction, the numerator of which is the
outstanding principal amount of Loans at the time of and before giving effect to
such prepayment and the denominator of which is the aggregate principal amount
of all Eligible Secured Debt (including the Loans) outstanding at such time the
terms of which require such mandatory prepayment.

         SECTION 2.10. Fees. (a) The Borrower agrees to pay to the
Administrative Agent for the account of each Lender a commitment fee, which
shall accrue at the Commitment Fee Rate on the daily amount of the Commitment of
such Lender during the period from and including the Effective Date to but
excluding the date on which the Commitments terminate; provided that commitment
fees shall not commence to accrue with respect to Contingent Commitments until
the Full Availability Date. Accrued commitment fees shall be payable in arrears
on the last day of March, June, September and December of each year and on the
date on which the Commitments terminate, commencing on the first such date to
occur after the Effective Date. All commitment fees shall be computed on the
basis of a year of 360 days and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).

         (b) The Borrower agrees to pay to Lucent, for its own account, fees in
the amounts and at the times separately agreed.

         (c) The Borrower agrees to pay to the Administrative Agent and the
Collateral Agent (if other than Lucent), for its own account, fees in the
amounts and at the times separately agreed.

         (d) All fees payable hereunder shall be paid on the dates due, in
immediately available funds, (i) to the applicable Agent, (ii) to Lucent, in the
case of fees payable to it, or (iii) to the Administrative Agent, in the case of
commitment fees, for distribution to the Lenders entitled thereto. Fees paid
shall not be refundable under any circumstances.

         SECTION 2.11. Interest. (a) The Loans comprising each ABR Borrowing
shall bear interest at the Alternate Base Rate plus the Applicable Margin.


<PAGE>   55
                                                                              49


         (b) The Loans comprising each LIBOR Borrowing shall bear interest at
the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus
the Applicable Margin.

         (c) Notwithstanding the foregoing, if any principal of or interest on
any Loan or any fee or other amount payable by the Borrower hereunder is not
paid when due, whether at stated maturity, upon acceleration or otherwise, such
overdue amount shall bear interest, after as well as before judgment, at a rate
per annum equal to 2% plus the rate applicable to ABR Loans as provided in
paragraph (a) of this Section.

         (d) All accrued interest on each Loan shall be payable in arrears on
each Interest Payment Date for such Loan; provided that (i) interest accrued
pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in
the event of any repayment or prepayment of any Loan, accrued interest on the
principal amount of such Loan repaid or prepaid shall be payable on the date of
such repayment or prepayment, and (iii) in the event of any conversion of any
Loan prior to the end of the current Interest Period therefor, accrued interest
on such Loan shall be payable on the effective date of such conversion.

         (e) All interest hereunder shall be computed on the basis of a year of
360 days, except that interest computed by reference to the Alternate Base Rate
at times when the Alternate Base Rate is based on the Prime Rate shall be
computed on the basis of a year of 365 days (or 366 days in a leap year), and in
each case shall be payable for the actual number of days elapsed (including the
first day but excluding the last day). The applicable Alternate Base Rate or
Adjusted LIBO Rate shall be determined by the Administrative Agent, and such
determination shall be conclusive absent manifest error.

         SECTION 2.12. Alternate Rate of Interest. If prior to the commencement
of any Interest Period for a LIBOR Borrowing:

                  (a) the Administrative Agent determines (which determination
         shall be conclusive absent manifest error) that adequate and reasonable
         means do not exist for ascertaining the Adjusted LIBO Rate for such
         Interest Period; or


<PAGE>   56
                                                                              50


                  (b) the Administrative Agent is advised by a majority in
         interest of the Lenders participating in such Borrowing that the
         Adjusted LIBO Rate for such Interest Period will not adequately and
         fairly reflect the cost to such Lenders of making or maintaining their
         Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a LIBOR Borrowing shall be ineffective and
(ii) if any Borrowing Request requests a LIBOR Borrowing, such Borrowing shall
be made as an ABR Borrowing.

         SECTION 2.13. Increased Costs. (a) If any Change in Law shall:

                  (i) impose, modify or deem applicable any reserve, special
         deposit or similar requirement against assets of, deposits with or for
         the account of, or credit extended by, any Lender (except any such
         reserve requirement reflected in the Adjusted LIBO Rate); or

                  (ii) impose on any Lender or the London interbank market any
         other condition affecting this Agreement or LIBOR Loans made by such
         Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any LIBOR Loan (or of maintaining its obligation
to make any such Loan) or to reduce the amount of any sum received or receivable
by such Lender hereunder (whether of principal, interest or otherwise), then the
Borrower will pay to such Lender such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.

         (b) If any Lender determines that any Change in Law regarding capital
requirements has or would have the effect of reducing the rate of return on such
Lender's capital or on the capital of such Lender's holding company, if any, as
a consequence of this Agreement or the Loans made by such Lender to a level
below that which such Lender or such Lender's holding company could have
achieved but for


<PAGE>   57
                                                                              51


such Change in Law (taking into consideration such Lender's policies and the
policies of such Lender's holding company with respect to capital adequacy),
then from time to time the Borrower will pay to such Lender such additional
amount or amounts as will compensate such Lender or such Lender's holding
company for any such reduction suffered.

         (c) A certificate of a Lender setting forth the amount or amounts
necessary to compensate such Lender or its holding company, as the case may be,
as specified in paragraph (a) or (b) of this Section shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

         (d) Failure or delay on the part of any Lender to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender's right to
demand such compensation; provided that the Borrower shall not be required to
compensate a Lender pursuant to this Section for any increased costs or
reductions incurred more than 180 days prior to the date that such Lender
notifies the Borrower of the Change in Law giving rise to such increased costs
or reductions and of such Lender's intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such increased costs
or reductions is retroactive, then the 180-day period referred to above shall be
extended to include the period of retroactive effect thereof.

         SECTION 2.14. Break Funding Payments. In the event of (a) the payment
of any principal of any LIBOR Loan other than on the last day of an Interest
Period applicable thereto (including as a result of an Event of Default), (b)
the conversion of any LIBOR Loan other than on the last day of the Interest
Period applicable thereto, (c) the failure to borrow, convert, continue or
prepay any Loan on the date specified in any notice delivered pursuant hereto,
or (d) the assignment of any LIBOR Loan other than on the last day of the
Interest Period applicable thereto as a result of a request by the Borrower
pursuant to Section 2.17, then, in any such event, the Borrower shall compensate
each Lender for the loss, cost and expense attributable to such event. In the
case of a LIBOR Loan, such loss, cost or expense to any Lender shall be deemed
to include an amount determined by such Lender to be the excess, if any, of (i)
the amount of interest which would


<PAGE>   58
                                                                              52


have accrued on the principal amount of such Loan had such event not occurred,
at the Adjusted LIBO Rate that would have been applicable to such Loan, for the
period from the date of such event to the last day of the then current Interest
Period therefor (or, in the case of a failure to borrow, convert or continue,
for the period that would have been the Interest Period for such Loan), over
(ii) the amount of interest which would accrue on such principal amount for such
period at the interest rate which such Lender would bid were it to bid, at the
commencement of such period, for dollar deposits of a comparable amount and
period from other banks in the eurodollar market. A certificate of any Lender
setting forth any amount or amounts that such Lender is entitled to receive
pursuant to this Section shall be delivered to the Borrower and shall be
conclusive absent manifest error. The Borrower shall pay such Lender the amount
shown as due on any such certificate within 10 days after receipt thereof.

         SECTION 2.15. Taxes. (a) Any and all payments by or on account of any
obligation of the Borrower hereunder or under any other Loan Document shall be
made free and clear of and without deduction for any Indemnified Taxes or Other
Taxes; provided that if the Borrower shall be required to deduct any Indemnified
Taxes or Other Taxes from such payments, then (i) the sum payable shall be
increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section) the
Administrative Agent or Lender receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such
deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant Governmental Authority in accordance with applicable law.

         (b) In addition, the Borrower shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

         (c) The Borrower shall indemnify the Administrative Agent and each
Lender, within 10 days after written demand therefor, for the full amount of any
Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender
on or with respect to any payment by or on account of any obligation of the
Borrower hereunder or under any other Loan Document (including Indemnified Taxes
or Other Taxes imposed or asserted on or attributable to amounts payable under
this Section) and any penalties,


<PAGE>   59
                                                                              53


interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate as to
the amount of such payment or liability delivered to the Borrower by a Lender,
or by the Administrative Agent on its own behalf or on behalf of a Lender, shall
be conclusive absent manifest error.

         (d) As soon as practicable after any payment of Indemnified Taxes or
Other Taxes by the Borrower to a Governmental Authority, the Borrower shall
deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

         (e) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the United States of America, or
any treaty to which the United States of America is a party, with respect to
payments under this Agreement shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law, such
properly completed and executed documentation prescribed by applicable law or
reasonably requested by the Borrower as will permit such payments to be made
without withholding or at a reduced rate; provided that such Foreign Lender has
received written notice from the Borrower advising it of the availability of
such exemption or reduction and supplying all applicable documentation.

         SECTION 2.16. Payments Generally; Pro Rata Treatment; Sharing of
Set-Offs. (a) The Borrower shall make each payment required to be made by it
hereunder or under any other Loan Document (whether of principal, interest or
fees, or of amounts payable under Section 2.13, 2.14 or 2.15, or otherwise)
prior to 12:00 (noon), New York City time, on the date when due, in immediately
available funds, without set-off or counterclaim. Any amounts received after
such time on any date may, in the discretion of the Administrative Agent, be
deemed to have been received on the next succeeding Business Day for purposes of
calculating interest thereon. All such payments shall be made to the
Administrative Agent at The Chase Manhattan Bank, New York, New York, ABA no.
021000021, account no. 9101449099, phone no. (212) 552-2222 (or such other

                                                                              54


account in New York, New York as the Administrative Agent shall from time to
time specify by notice), except that payments pursuant to Sections 2.10(b),
2.10(c), 2.13, 2.14, 2.15 and 9.03 shall be made directly to the Persons
entitled thereto and payments pursuant to other Loan Documents shall be made to
the Persons specified therein. The Administrative Agent shall distribute any
such payments received by it for the account of any other Person to the
appropriate recipient promptly following receipt thereof. If any payment under
any Loan Document shall be due on a day that is not a Business Day, the date for
payment shall be extended to the next succeeding Business Day, and, in the case
of any payment accruing interest, interest thereon shall be payable for the
period of such extension. All payments under each Loan Document shall be made in
dollars.

         (b) Each repayment or prepayment of principal of the Loans hereunder,
or selection of Borrowings for repayment or prepayment, shall be made such that
the benefit of such repayment or prepayment is shared by the Lenders ratably in
accordance with the aggregate principal amount of their respective Loans then
outstanding.

         (c) If at any time insufficient funds are received by and available to
the Administrative Agent to pay fully all amounts of principal, interest and
fees then due hereunder, such funds shall be applied (i) first, towards payment
of interest and fees then due hereunder, ratably among the parties entitled
thereto in accordance with the amounts of interest and fees then due to such
parties, and (ii) second, towards payment of principal then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of
principal then due to such parties.

         (d) If any Lender shall, by exercising any right of set-off or
counterclaim or otherwise, obtain payment in respect of any principal of or
interest on any of its Loans resulting in such Lender receiving payment of a
greater proportion of the aggregate amount of its Loans and accrued interest
thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value)
participations in the Loans of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in
accordance with the aggregate amount of principal of and accrued interest on
their respective Loans; provided that (i) if any such participations are
purchased


<PAGE>   61
                                                                              55


and all or any portion of the payment giving rise thereto is recovered, such
participations shall be rescinded and the purchase price restored to the extent
of such recovery, without interest, and (ii) the provisions of this paragraph
shall not be construed to apply to any payment made by the Borrower pursuant to
and in accordance with the express terms of this Agreement or any payment
obtained by a Lender as consideration for the assignment of or sale of a
participation in any of its Loans to any assignee or participant, other than to
the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions
of this paragraph shall apply). The Borrower consents to the foregoing and
agrees, to the extent it may effectively do so under applicable law, that any
Lender acquiring a participation pursuant to the foregoing arrangements may
exercise against the Borrower rights of set-off and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of the
Borrower in the amount of such participation.

         (e) Unless the Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders hereunder that the Borrower will not make
such payment, the Administrative Agent may assume that the Borrower has made
such payment on such date in accordance herewith and may, in reliance upon such
assumption, distribute to the Lenders the amount due. In such event, if the
Borrower has not in fact made such payment, then each of the Lenders severally
agrees to repay to the Administrative Agent forthwith on demand the amount so
distributed to such Lender with interest thereon, for each day from and
including the date such amount is distributed to it to but excluding the date of
payment to the Administrative Agent, at the greater of the Federal Funds
Effective Rate and a rate determined by the Administrative Agent in accordance
with banking industry rules on interbank compensation.

         (f) Without limiting the generality of paragraph (a) above, the
Borrower's obligations to make each payment required to be made by it hereunder
or under any other Loan Document (whether of principal, interest, fees or
otherwise) shall be absolute and unconditional and shall not be subject to any
delay, reduction, set-off, counterclaim, defense or recoupment for any reason,
including any dispute with, breach of representation or warranty by or claim
against any supplier, manufacturer, installer, vendor or distributer, including
Lucent.

         SECTION 2.17. Mitigation Obligations; Replacement of Lenders. (a) If
any Lender requests compensation under Section 2.13, or if the Borrower is
required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 2.15, then such
Lender shall use reasonable efforts to designate a different lending office for
funding or booking its Loans hereunder or to assign its rights and obligations
hereunder to another of its offices, branches or affiliates, if, in the judgment
of such Lender, such designation or assignment (i) would eliminate or reduce
amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the
future and (ii) would not subject such Lender to any unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender. The Borrower
hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

         (b) If any Lender requests compensation under Section 2.13, or if the
Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to Section 2.15,
then the Borrower may, at its sole expense and effort, upon notice to such
Lender and the Administrative Agent, require such Lender to assign and delegate,
without recourse (in accordance with and subject to the restrictions contained
in Section 9.04), all its interests, rights and obligations under this Agreement
to an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Borrower
shall have received the prior written consent of the Administrative Agent, which
consent shall not unreasonably be withheld, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of its Loans, accrued
interest thereon, accrued fees and all other amounts payable to it hereunder,
from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the Borrower (in the case of all other amounts) and (iii)
such assignment will result in a material reduction in such compensation or
payments. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling the Borrower to require such assignment
and delegation cease to apply.

                                   ARTICLE III

                         Representations and Warranties

         Each of Holdings and the Borrower represents and warrants to the
Lenders that:

         SECTION 3.01. Organization; Powers. Each of the Loan Parties is duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, has all requisite power and authority to carry
on its business as now conducted and, except where the failure to do so,
individually or in the aggregate, could not reasonably be expected to result in
a Material Adverse Effect, is qualified to do business in, and is in good
standing in, every jurisdiction where such qualification is required.

         SECTION 3.02. Authorization; Enforceability. The Transactions entered
into or to be entered into by each Loan Party are within such Loan Party's
powers and have been duly authorized by all necessary corporate and, if
required, stockholder action. This Agreement has been duly executed and
delivered by Holdings and the Borrower and constitutes, and each other Loan
Document to which any Loan Party is or is to be a party constitutes (or, when
executed and delivered by it, will constitute) a legal, valid and binding
obligation of Holdings and the Borrower or such Loan Party (as the case may be),
enforceable in accordance with its terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium or other laws affecting creditors' rights
generally and subject to general principles of equity, regardless of whether
considered in a proceeding in equity or at law.

         SECTION 3.03. Governmental Approvals; No Conflicts. The Transactions
(a) do not require any consent or approval of, registration or filing with, or
any other action by, any Governmental Authority, except such as have been
obtained or made and are in full force and effect and except filings necessary
to perfect Liens created under the Security Documents, (b) will not violate any
applicable law or regulation or the charter, by-laws or other organizational
documents of any Loan Party or any order of any Governmental Authority, (c) will
not violate or result in a default under any indenture, agreement or other
instrument binding upon any Loan Party or its assets, or give rise to a right
thereunder to require any payment to be made by any


<PAGE>   64
                                                                              58


Loan Party, except for, until the consents and waivers required by Section
4.02(j) are received, the Credit Agreement dated as of September 23, 1998 among
the Parent, QUALCOMM Incorporated and ABN Amro Bank N.V., as Administrative
Agent, and (d) will not result in the creation or imposition of any Lien on any
asset of any Loan Party, except Liens created under the Security Documents.

         SECTION 3.04. Financial Condition; No Material Adverse Change. (a) The
Parent has heretofore furnished to the Lenders its consolidated balance sheet
and statements of income, stockholders equity and cash flows (i) as of and for
the fiscal year ended August 31, 1998, reported on by PricewaterhouseCoopers
LLP, independent public accountants, and (ii) as of and for the fiscal quarter
and the portion of the fiscal year ended May 31, 1999, certified by its chief
financial officer. Such financial statements present fairly, in all material
respects, the financial position and results of operations and cash flows of the
Parent and its consolidated subsidiaries as of such dates and for such periods
in accordance with GAAP, subject to year-end audit adjustments and the absence
of footnotes in the case of the statements referred to in clause (ii) above.

         (b) The Borrower has heretofore furnished to the Lenders its
consolidated balance sheet and statement of operations, stockholder's equity and
cash flows as of and for the fiscal year ended August 31, 1998, and as of and
for the portion of the fiscal year ended June 21, 1999, certified by its chief
financial officer. Such financial statements present fairly, in all material
respects, the financial position and results of operations and cash flows of the
Borrower and its consolidated subsidiaries as of such dates and for such periods
in accordance with GAAP.

         (c) Since June 21, 1999, there has been no material adverse change in
the business, assets, operations, prospects or condition (financial or
otherwise) of the Borrower and the Subsidiary Loan Parties, taken as a whole.

         SECTION 3.05. Properties and Licenses. (a) Each of the Borrower and the
Subsidiary Loan Parties has good title to, or valid leasehold interests in, all
the real and personal property material to its business (other than licenses,
which are addressed in paragraph (d) of this Section), except for minor defects
in title that do not interfere with its ability to conduct its business as
currently conducted or proposed to be conducted.

                                                                              59


         (b) Each of the Borrower and the Subsidiary Loan Parties owns, or is
licensed to use, all trademarks, tradenames, copyrights, patents and other
intellectual property material to its business, and the use thereof by the
Borrower and the Subsidiary Loan Parties does not infringe upon the rights of
any other Person, except for any such infringements that, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse
Effect.

         (c) Schedule 3.05A sets forth the address of each real property that is
owned or leased by the Borrower or any of its Subsidiaries as of the Effective
Date after giving effect to the Transactions. As of the Effective Date, neither
Holdings, the Borrower nor any of its Subsidiaries has received notice of, or
has knowledge of, any pending or contemplated condemnation proceeding affecting
any Mortgaged Property or any sale or disposition thereof in lieu of
condemnation. Neither any Mortgaged Property nor any interest therein is subject
to any right of first refusal, option or other contractual right to purchase
such Mortgaged Property or interest therein.

         (d) Schedule 3.05B sets forth all FCC Licenses existing as of the
Effective Date (and the respective holders of such FCC Licenses) and all other
licenses and permits in effect as of the Effective Date that are material to the
business of the Borrower and the Subsidiary Loan Parties. Each of the FCC
Licenses, and each other license or permit that is material to the business of
the Borrower and the Subsidiary Loan Parties, is valid and in full force and
effect, and the Borrower and the Subsidiary Loan Parties are in compliance with
the terms and conditions thereof except where the failure to so comply could
not, individually or in the aggregate, reasonably be expected to result in a
Material Adverse Effect.

         SECTION 3.06. Litigation and Environmental Matters. (a) There are no
actions, suits or proceedings by or before any arbitrator or Governmental
Authority pending against or, to the knowledge of Holdings or the Borrower,
threatened against or affecting any Loan Party (i) as to which there is a
reasonable possibility of an adverse determination and that, if adversely
determined, could reasonably be expected, individually or in the aggregate, to
result in a Material Adverse Effect (other than the


<PAGE>   66
                                                                              60


Disclosed Matters) or (ii) that involve any of the Loan Documents or the
Transactions.

         (b) Except for the Disclosed Matters and except with respect to any
other matters that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, none of the Loan Parties (i)
has failed to comply with any Environmental Law or to obtain, maintain or comply
with any permit, license or other approval required under any Environmental Law,
(ii) has become subject to any Environmental Liability, (iii) has received
notice of any claim with respect to any Environmental Liability or (iv) knows of
any basis for any Environmental Liability.

         (c) Since the date of this Agreement, there has been no change in the
status of the Disclosed Matters that, individually or in the aggregate, has
resulted in, or materially increased the likelihood of, a Material Adverse
Effect.

         SECTION 3.07. Compliance with Laws and Agreements. Each of the Loan
Parties is in compliance with all laws, regulations and orders of any
Governmental Authority applicable to it or its property and all indentures,
agreements and other instruments binding upon it or its property, except where
the failure to do so, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, except for, until the consents
and waivers required by Section 4.02(j) are received, the Credit Agreement dated
as of September 23, 1998 among the Parent, QUALCOMM Incorporated and ABN Amro
Bank N.V., as Administrative Agent. No Default has occurred and is continuing.

         SECTION 3.08. Investment and Holding Company Status. None of the Loan
Parties is (a) an "investment company" as defined in, or subject to regulation
under, the Investment Company Act of 1940 or (b) a "holding company" as defined
in, or subject to regulation under, the Public Utility Holding Company Act of
1935.

         SECTION 3.09. Taxes. Each of the Loan Parties has timely filed or
caused to be filed all Tax returns and reports required to have been filed and
has paid or caused to be paid all Taxes required to have been paid by it, except
(a) Taxes that are being contested in good faith by appropriate proceedings and
for which the applicable Loan


<PAGE>   67
                                       61


Party has set aside on its books adequate reserves or (b) the filing of state or
local Tax returns and reports, or the payment of state or local Taxes, to the
extent that the failure to do so, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Effect.

         SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably
expected to occur that, when taken together with all other such ERISA Events for
which liability is reasonably expected to occur, could reasonably be expected to
result in a Material Adverse Effect. The present value of all accumulated
benefit obligations under each Plan (based on the assumptions used for purposes
of Statement of Financial Accounting Standards No. 87) did not, as of the date
of the most recent financial statements reflecting such amounts, exceed by more
than $1,000,000 the fair market value of the assets of such Plan, and the
present value of all accumulated benefit obligations of all underfunded Plans
(based on the assumptions used for purposes of Statement of Financial Accounting
Standards No. 87) did not, as of the date of the most recent financial
statements reflecting such amounts, exceed by more than $5,000,000 the fair
market value of the assets of all such underfunded Plans.

         SECTION 3.11. Disclosure. Holdings and the Borrower have disclosed to
the Lenders all agreements, instruments and corporate or other restrictions to
which any of the Loan Parties is subject, and all other matters known to any of
them, that, individually or in the aggregate, could reasonably be expected to
result in a Material Adverse Effect. None of the reports, financial statements,
certificates or other information furnished by or on behalf of any Loan Party to
the Administrative Agent or any Lender in connection with the negotiation of
this Agreement or any other Loan Document or delivered hereunder or thereunder
(as modified or supplemented by other information so furnished) contains any
material misstatement of fact or omits to state any material fact necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; provided that, with respect to projected financial
information, Holdings and the Borrower represent only that such information was
prepared in good faith based upon assumptions believed to be reasonable at the
time.

         SECTION 3.12. Subsidiaries. Holdings does not have any subsidiaries
other than the Borrower and the Borrower's Subsidiaries. Schedule 3.12 sets
forth as of the


<PAGE>   68
                                                                              62


Effective Date (a) the name of, and the ownership interest of the Borrower in,
each Subsidiary of the Borrower and (b) the name of, and the ownership interest
of the Parent in, each License Subsidiary.

         SECTION 3.13. Insurance. Schedule 3.13 sets forth a description of all
insurance maintained by or on behalf of the Borrower and the Subsidiary Loan
Parties as of the Effective Date. As of the Effective Date, all premiums then
due and payable in respect of such insurance have been paid.

         SECTION 3.14. Labor Matters. As of the Effective Date, there are no
strikes, lockouts or slowdowns against any Loan Party pending or, to the
knowledge of Holdings or the Borrower, threatened. The hours worked by and
payments made to employees of the Loan Parties have not been in violation of the
Fair Labor Standards Act or any other applicable Federal, state, local or
foreign law dealing with such matters. All payments due from any Loan Party, or
for which any claim may be made against any Loan Party, on account of wages and
employee health and welfare insurance and other benefits, have been paid or
accrued as a liability on the books of the applicable Loan Party. The
consummation of the Transactions will not give rise to any right of termination
or right of renegotiation on the part of any union under any collective
bargaining agreement to which any Loan Party is bound.

         SECTION 3.15. Purchase Agreement. The Purchase Agreement is in full
force and effect. The Borrower is in compliance in all material respects with
the terms and conditions of the Purchase Agreement.

         SECTION 3.16. Year 2000. Any reprogramming required to permit the
proper functioning, in and following the year 2000, of (a) the computer systems
of the Borrower and its Subsidiaries (including any computer systems of the
Parent that are used in connection with the business of the Borrower and its
Subsidiaries) and (b) equipment containing embedded microchips (including
systems and equipment supplied by others or with which the Borrower's systems
interface) and the testing of all such systems and equipment, as so
reprogrammed, have been completed. The cost to the Borrower and its Subsidiaries
of such reprogramming and testing and of the reasonably foreseeable consequences
of year 2000 to the Borrower and its Subsidiaries (including reprogramming
errors and the failure of others' systems or


<PAGE>   69
                                                                              63


equipment) will not result in a Default or a Material Adverse Effect.

                                   ARTICLE IV

                                   Conditions

         SECTION 4.01. Effective Date. The obligations of the Lenders to make
Loans hereunder shall not become effective until the date on which each of the

well as such other insurance as may be required by law.

         (b) All policies of casualty insurance maintained by or for the benefit
of the Borrower or any Subsidiary Loan Party with respect to any of the

the Collateral Agent, which endorsement shall provide that the insurance carrier
shall pay all proceeds otherwise payable to any Loan Party under such policies
directly to the Collateral Agent. All such policies also shall provide that none

other party shall be a coinsurer thereunder and shall contain a "Replacement
Cost Endorsement", without any deduction for depreciation, "mortgagee's
interest"/"breach of warranty coverage" and such other provisions as the
Administrative Agent or the Collateral Agent may reasonably require from time to
time to protect the interests of the Lenders. Each such policy also shall
provide that it shall not be canceled, modified or not renewed (i) by reason of
nonpayment of premium except upon not less than 10 days' prior written notice
thereof by the insurer to the Administrative Agent and the Collateral Agent
(giving the Administrative Agent and the Collateral Agent the right to cure
defaults in the payment of premiums) or (ii) for any other reason except upon
not less than 30 days' prior written notice thereof by the insurer to the
Administrative Agent and the Collateral Agent. The Borrower shall deliver to the
Administrative Agent and the Collateral Agent, prior to the cancelation,
modification or nonrenewal of any such policy of insurance, a copy of a renewal

payment of the premium therefor.

         (c) The Borrower shall notify the Administrative Agent and the

Subsidiary Loan Parties to, permit any representatives designated by either
Agent or any Lender, upon reasonable prior notice, to visit and inspect its
properties, to examine and make extracts from its books and records, and to

(including ERISA and all Environmental Laws) applicable to it or its property

property, except where the failure to do so, individually or in the aggregate,
could not reasonably be expected to result in a Material Adverse Effect.

solely (a) to make payments in respect of the Purchase Price and Permitted Third
Party Payments and (b) to pay fees payable under Sections 2.10(a), 2.10(b) and

acquired, (a) notify the Agents and the Lenders thereof, (b) cause the
Collateral and Guarantee Requirement to be satisfied with respect to such

reasonably satisfactory to the Agents as to the perfection and priority of the
Liens created or intended to be created by the Security Documents.

         (b) If any material assets (including any real property or improvements
thereto or any interest therein, but excluding Equipment Site Interests acquired
by Real Estate Subsidiaries) are acquired by the Borrower or any Subsidiary Loan
Party after the Effective Date (other than assets constituting Collateral under
the Security Agreement that become subject to the Lien of the Security Agreement
upon acquisition thereof), the Borrower will notify the Agents and the Lenders
thereof, and, if requested by the Administrative Agent or the Required Lenders,
the Borrower will cause such assets to be subjected to a Lien securing the
Obligations and will take, and cause the Subsidiary Loan Parties to take, such
actions as shall be necessary or reasonably requested by the Administrative
Agent to grant and perfect such Liens, including actions described in paragraph
(a) of this Section, all at the expense of the Loan Parties.

         SECTION 5.13. Casualty and Condemnation. (a) The Borrower will furnish
to the Agents and the Lenders prompt written notice of any casualty or other
damage to any portion of any Collateral or the commencement of any action or
proceeding for the taking of any Collateral or any part thereof or interest

Collateral Agent is authorized to collect such Net Proceeds and, if received by
the Borrower or any Subsidiary Loan Party, such Net Proceeds shall be paid over
to the Collateral Agent. All such Net Proceeds retained by or paid over to the
Collateral Agent shall be held by the Collateral Agent and released from time to
time to pay the costs of repairing, restoring or replacing the affected property
or purchasing additional property constituting Collateral in accordance with the
terms of this Agreement and the applicable provisions of the Security Documents,

Agent as provided above continue to be held by the Collateral Agent on the date
that any prepayment is due pursuant to Section 2.09(b) in respect of the event
resulting in such Net Proceeds, then such Net Proceeds shall be applied to
prepay Borrowings as provided in Section 2.09(b).

         SECTION 5.14. Interest Rate Protection. After the consolidated
Long-Term Indebtedness (excluding Primary Subordinated Obligations) of the
Borrower and the Subsidiary Loan Parties exceeds $225,000,000, the Borrower will
from time to time enter into and maintain in effect one or more Hedging
Agreements satisfactory to the Required Lenders, the effect of which shall be to
fix or limit the interest cost to the Borrower and the Subsidiary Loan Parties
with respect to such portion of their Long-Term Indebtedness as shall be
necessary in order that, at all times, at least 50% of consolidated Long-Term
Indebtedness (excluding Primary Subordinated Obligations) of the Borrower and
the Subsidiary Loan Parties shall be comprised of a combination of (a)
Indebtedness bearing interest at a fixed rate and (b) Indebtedness covered by

this Article), and at any time thereafter during the continuance of such event,
the Administrative Agent may, and at the request of the Required Lenders shall,
by notice to the Borrower, take either or both of the following actions, at the
same or different times: (i) terminate the Commitments, and thereupon the
Commitments shall terminate immediately, and (ii) declare the Loans then

and payable, together with accrued interest thereon and all fees and other
obligations of the Borrower accrued hereunder, shall become due and payable
immediately, without presentment, demand, protest or other notice of any kind,
all of which are hereby waived by the Borrower; and in case of any event with

all of which are hereby waived by the Borrower.

                                   The Agents

               Each of the Lenders hereby irrevocably appoints the
Administrative Agent as its agent and authorizes the Administrative Agent to
take such actions on its behalf and to exercise such powers as are delegated to
the Administrative Agent by the terms of the Loan Documents, together with such
actions and powers as are reasonably incidental thereto.

               Any Person serving as Administrative Agent hereunder shall have
the same rights and powers in its capacity as a Lender as any other Lender and
may exercise the same as though it were not the Administrative Agent, and such
Person and its Affiliates may accept deposits from, lend money to and generally
engage in any kind of business with the Borrower or any Subsidiary or other
Affiliate thereof as if it were not the Administrative Agent hereunder.

                                                                              99


               The Administrative Agent shall not have any duties or obligations
except those expressly set forth in the Loan Documents. Without limiting the
generality of the foregoing, (a) the Administrative Agent shall not be subject
to any fiduciary or other implied duties, regardless of whether a Default has
occurred and is continuing, (b) the Administrative Agent shall not have any duty
to take any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated by the Loan Documents
that the Administrative Agent is required to exercise in writing by the Required
Lenders (or such other number or percentage of the Lenders as shall be necessary
under the circumstances as provided in Section 9.02), and (c) except as
expressly set forth in the Loan Documents, the Administrative Agent shall not
have any duty to disclose, and shall not be liable for the failure to disclose,
any information relating to any of the Loan Parties that is communicated to or
obtained by the Person serving as Administrative Agent or any of its Affiliates
in any capacity. The Administrative Agent shall not be liable for any action
taken or not taken by it with the consent or at the request of the Required
Lenders (or such other number or percentage of the Lenders as shall be necessary
under the circumstances as provided in Section 9.02) or in the absence of its
own gross negligence or wilful misconduct. The Administrative Agent shall be
deemed not to have knowledge of any Default unless and until written notice
thereof is given to it by the Borrower or a Lender, and the Administrative Agent
shall not be responsible for or have any duty to ascertain or inquire into (i)
any statement, warranty or representation made in or in connection with any Loan
Document, (ii) the contents of any certificate, report or other document
delivered thereunder or in connection therewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth in any Loan Document, (iv) the validity, enforceability, effectiveness or
genuineness of any Loan Document or any other agreement, instrument or document,
or (v) the satisfaction of any condition set forth in Article IV or elsewhere in
any Loan Document, other than to confirm receipt of items expressly required to
be delivered to the Administrative Agent.

               The Administrative Agent shall be entitled to rely upon, and
shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing believed
by it to be genuine and to have been signed or sent by the proper


<PAGE>   106
                                                                             100


Person. The Administrative Agent also may rely upon any statement made to it
orally or by telephone and believed by it to be made by the proper Person, and
shall not incur any liability for relying thereon. The Administrative Agent may
consult with legal counsel (who may be counsel for the Borrower), independent
accountants and other experts selected by it, and shall not be liable for any
action taken or not taken by it in accordance with the advice of any such
counsel, accountants or experts.

               The Administrative Agent may perform any and all its duties and
exercise its rights and powers by or through any one or more sub-agents
appointed by the Administrative Agent. The Administrative Agent and any such
sub-agent may perform any and all its duties and exercise its rights and powers
through their respective Related Parties. The exculpatory provisions of the
preceding paragraphs shall apply to any such sub-agent and to the Related
Parties of the Administrative Agent and any such sub-agent, and shall apply to
their respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as Administrative Agent.

               Subject to the appointment and acceptance of a successor
Administrative Agent as provided in this paragraph, the Administrative Agent may
resign at any time by notifying the Lenders and the Borrower. Upon any such
resignation, the Required Lenders shall have the right to appoint a successor.
If no successor shall have been so appointed by the Required Lenders and shall
have accepted such appointment within 30 days after the retiring Administrative
Agent gives notice of its resignation, then the retiring Administrative Agent
may, on behalf of the Lenders, appoint a successor Administrative Agent which
shall be a bank with an office in New York, New York, or an Affiliate of any
such bank. Upon the acceptance of its appointment as Administrative Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. The fees payable by the Borrower to a successor
Administrative Agent shall be the same as those payable to its predecessor
unless otherwise agreed between the Borrower and such successor. After the
Administrative Agent's resignation hereunder, the provisions of this Article and
Section 9.03 shall continue in effect for the benefit of such retiring
Administrative Agent, its

                                                                             101


sub-agents and their respective Related Parties in respect of any actions taken
or omitted to be taken by any of them while it was acting as Administrative
Agent.

               Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any other Loan Document or related agreement or any document furnished hereunder
or thereunder.

               Each Lender acknowledges and agrees to the terms of the
Collateral Agency Agreement and to the appointment of the Collateral Agent to
act as collateral agent under the Collateral Agency Agreement and the other
Security Documents.

other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

               SECTION 9.02. Waivers; Amendments. (a) No failure or delay by
either Agent or any Lender in exercising any right or power hereunder or under
any other Loan Document shall operate as a waiver thereof, nor shall any single
or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Agents and the Lenders hereunder and under the other Loan
Documents are cumulative and are not exclusive of any rights or remedies that
they would otherwise have. No waiver of any provision of any Loan Document or
consent to any departure by any Loan Party therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given. Without limiting the generality of the
foregoing, the making of a Loan shall not be construed as a waiver of any
Default, regardless of whether an Agent or any Lender may have had notice or
knowledge of such Default at the time.

               (b) Neither this Agreement nor any other Loan Document nor any
provision hereof or thereof may be waived, amended or modified except, in the
case of this Agreement, pursuant to an agreement or agreements in writing
entered into by Holdings, the Borrower and the Required Lenders or, in the case
of any other Loan Document, pursuant to an agreement or agreements in writing
entered into by the applicable Agent and the Loan Party or Loan Parties that are
parties thereto, in each case with the consent of the Required Lenders; provided
that no such agreement shall

(i) increase the Commitment of any Lender without the written consent of such
Lender, (ii) reduce the principal amount of any Loan or reduce the rate of
interest on such Loan, or reduce any fees payable hereunder, without the written
consent of each Lender affected thereby, (iii) postpone the scheduled date of
payment of the principal amount of any Loan or any interest thereon, or any fees
payable hereunder, or reduce the amount of, waive or excuse any such payment, or
postpone the scheduled date of expiration of any Commitment, without the written
consent of each Lender affected thereby, (iv) change Section 2.16(b), (c) or (d)
in a manner that would alter the pro rata sharing of payments required thereby,
without the written consent of each Lender, (v) change any of the provisions of
this Section or the definition of "Required Lenders" or any other provision of
any Loan Document specifying the number or percentage of Lenders required to
waive, amend or modify any rights thereunder or make any determination or grant
any consent thereunder, without the written consent of each Lender, (vi) release
all or any substantial part of the Collateral from the Lien of any Security
Document (except as expressly provided in such Security Document), without the
written consent of each Lender, (vii) release Holdings or any Subsidiary Loan
Party from its Guarantee under the Guarantee Agreement (except as expressly
provided in the Guarantee Agreement), or limit its liability in respect of such
Guarantee or (viii) change any provisions of any Security Document in a manner
that adversely affects the pro rata security of the Loans in relation to any
other Eligible Secured Debt, without the written consent of each Lender;
provided further that no such agreement shall amend, modify or otherwise affect
the rights or duties of either Agent without the prior written consent of such
Agent.

               SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) The
Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by Lucent
and each Agent, including the reasonable fees, charges and disbursements of
counsel for Lucent or the Agents, in connection with the preparation and
administration of the Loan Documents or any amendments, modifications or waivers
thereof (whether or not the transactions contemplated hereby are consummated)
and (ii) all reasonable out-of-pocket expenses incurred by either Agent or any
Lender, including the reasonable fees, charges and disbursements of any counsel
for either Agent or any Lender, in connection with the enforcement or protection
of its rights in connection with the Loan Documents, including its rights under
this Section, or in connection

                                                                             104


with the Loans made hereunder, including all such costs and expenses incurred
during any workout, restructuring or negotiations in respect of such Loans.

               (b) The Borrower shall indemnify each Agent and each Lender, and
each Related Party of any of the foregoing Persons (each such Person being
called an "Indemnitee") against, and hold each Indemnitee harmless from, any and
all losses, claims, damages, liabilities and related expenses, including the
fees, charges and disbursements of any counsel for any Indemnitee, incurred by
or asserted against any Indemnitee arising out of, in connection with, or as a
result of (i) the execution or delivery of any Loan Document or any other
agreement or instrument contemplated hereby, the performance by the parties to
the Loan Documents of their respective obligations thereunder or the
consummation of the Transactions or any other transactions contemplated hereby,
(ii) any Loan or the use of the proceeds therefrom, (iii) any actual or alleged
presence or release of Hazardous Materials on or from any Mortgaged Property or
any other property at any time owned or operated by the Borrower or any of its
Subsidiaries, or any Environmental Liability related in any way to the Borrower
or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation,
investigation or proceeding relating to any of the foregoing, whether based on
contract, tort or any other theory and regardless of whether any Indemnitee is a
party thereto; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses have resulted from the gross negligence or wilful misconduct of
such Indemnitee.

               (c) To the extent that the Borrower fails to pay any amount
required to be paid by it to the Administrative Agent under paragraph (a) or (b)
of this Section, each Lender severally agrees to pay to the Administrative Agent
such Lender's pro rata share (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount;
provided that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted
against the Administrative Agent in its capacity as such. For purposes hereof, a
Lender's "pro rata share" shall be determined based upon its share of the sum of
the total outstanding Loans and Commitments at the time.


<PAGE>   111
                                                                             105


               (d) To the extent permitted by applicable law, neither Holdings
nor the Borrower shall assert, and each of them hereby waives, any claim against
any Indemnitee, on any theory of liability, for special, indirect, consequential
or punitive damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of, this Agreement or any agreement or
instrument contemplated hereby, the Transactions, any Loan or the use of the
proceeds thereof.

               (e) All amounts due under this Section shall be payable not later
than 30 days after written demand therefor.

               SECTION 9.04. Successors and Assigns. (a) The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby, except that the
Borrower may not assign or otherwise transfer any of its rights or obligations
hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by the Borrower without such consent shall be null and
void). Nothing in this Agreement, expressed or implied, shall be construed to
confer upon any Person (other than the parties hereto, their respective
successors and assigns permitted hereby and, to the extent expressly
contemplated hereby, the Related Parties of each of the Agents and the Lenders)
any legal or equitable right, remedy or claim under or by reason of this
Agreement.

               (b) Any Lender may assign to one or more assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it); provided that
(i) except in the case of an assignment to Lucent, a Lender or an Affiliate of
Lucent or a Lender, the Administrative Agent must give its prior written consent
to such assignment (which consent shall not be unreasonably withheld or
delayed), (ii) in the case of an assignment to a competitor of the Borrower or
any of its Subsidiaries (or any Affiliate of any such competitor) or in the case
of an assignment of a Commitment (other than to an Eligible Assignee), the
Borrower must give its prior written consent to such assignment (which consent,
except in the case of an assignment to any such competitor or Affiliate of a
competitor, shall not be unreasonably withheld or delayed), (iii) except in the
case of an assignment to Lucent, a
<PAGE>   112
                                                                             106


Lender or an Affiliate of Lucent or a Lender or an assignment of the entire
remaining amount of the assigning Lender's Commitment and Loans, the amount of
the Commitment and Loans of the assigning Lender subject to each such assignment
(determined as of the date the Assignment and Acceptance with respect to such
assignment is delivered to the Administrative Agent) shall not be less than
$5,000,000 unless the Borrower otherwise consents, (iv) each partial assignment
shall be made as an assignment of a proportionate part of all the assigning
Lender's rights and obligations under this Agreement, except that this clause
(iv) shall not be construed to prohibit the assignment of a proportionate part
of all of the assigning Lender's rights and obligations in respect of (A) Loans
separately from (or without assigning) Commitments, (B) Commitments separately
from (or without assigning) Loans or (C) Commitments that are not Contingent
Commitments separately from (or without assigning) Contingent Commitments, (v)
the parties to each assignment shall execute and deliver to the Administrative
Agent an Assignment and Acceptance, together with a processing and recordation
fee of $3,500, and (vi) the assignee, if it shall not be a Lender, shall deliver
to the Administrative Agent an Administrative Questionnaire; provided further
that any consent of the Borrower otherwise required under this paragraph shall
not be required if an Event of Default under clause (h) or (i) of Article VII
has occurred and is continuing. Subject to acceptance and recording thereof
pursuant to paragraph (d) of this Section, from and after the effective date
specified in each Assignment and Acceptance the assignee thereunder shall be a
party hereto and, to the extent of the interest assigned by such Assignment and
Acceptance, have the rights and obligations of a Lender under this Agreement,
and the assigning Lender thereunder shall, to the extent of the interest
assigned by such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all of the assigning Lender's rights and obligations under this Agreement, such
Lender shall cease to be a party hereto but shall continue to be entitled to the
benefits of Sections 2.13, 2.14, 2.15 and 9.03). Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with
this paragraph shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
paragraph (e) of this Section.


<PAGE>   113
                                                                             107


               (c) The Administrative Agent, acting for this purpose as an agent
of the Borrower, shall maintain at one of its offices a copy of each Assignment
and Acceptance delivered to it and a register for the recordation of the names
and addresses of the Lenders, and the Commitments of, and principal amount of
the Loans owing to, each Lender pursuant to the terms hereof from time to time
(the "Register"). The entries in the Register shall be conclusive, and the
Borrower, the Agents and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement, notwithstanding notice to the contrary. The
Register shall be available for inspection by the Borrower and any Lender, at
any reasonable time and from time to time upon reasonable prior notice.

               (d) Upon its receipt of a duly completed Assignment and
Acceptance executed by an assigning Lender and an assignee, the assignee's
completed Administrative Questionnaire (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph
(b) of this Section and any written consent to such assignment required by
paragraph (b) of this Section, the Administrative Agent shall accept such
Assignment and Acceptance and record the information contained therein in the
Register. No assignment shall be effective for purposes of this Agreement unless
it has been recorded in the Register as provided in this paragraph.

               (e) Any Lender may, without the consent of the Borrower or the
Administrative Agent, sell participations to one or more banks or other entities
(a "Participant") in all or a portion of such Lender's rights and obligations
under this Agreement (including all or a portion of its Commitments and the
Loans owing to it); provided that (i) such Lender's obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (iii) the Borrower, the Agents and the other Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce the Loan Documents and to approve any amendment,
modification or waiver of any provision of the Loan Documents; provided that
such agreement or instrument may provide that such Lender will not, without the
consent of


<PAGE>   114
                                                                             108


the Participant, agree to any amendment, modification or waiver described in the
first proviso to Section 9.02(b) that affects such Participant. Subject to
paragraph (f) of this Section, the Borrower agrees that each Participant shall
be entitled to the benefits of Sections 2.13, 2.14 and 2.15 to the same extent
as if it were a Lender and had acquired its interest by assignment pursuant to
paragraph (b) of this Section. To the extent permitted by law, each Participant
also shall be entitled to the benefits of Section 9.08 as though it were a
Lender, provided such Participant agrees to be subject to Section 2.16(d) as
though it were a Lender.

               (f) A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 2.15 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with Section 2.15(e) as
though it were a Lender.

               (g) Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure
obligations of such Lender, including any pledge or assignment to secure
obligations to a Federal Reserve Bank, and this Section shall not apply to any
such pledge or assignment of a security interest; provided that no such pledge
or assignment of a security interest shall release a Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto.

               SECTION 9.05. Survival. All covenants, agreements,
representations and warranties made by the Loan Parties in the Loan Documents
and in the certificates or other instruments delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the other parties hereto and shall survive the
execution and delivery of the Loan Documents and the making of any Loans,
regardless of any investigation made by any such other party or on its behalf
and notwithstanding that either Agent or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as
long as the principal of or any accrued interest on any Loan or any fee or any
other amount payable under this Agreement is outstanding and unpaid and so long
as the Commitments have not expired or terminated. The provisions


<PAGE>   115
                                                                             109


of Sections 2.13, 2.14, 2.15 and 9.03 and Article VIII shall survive and remain
in full force and effect regardless of the consummation of the transactions
contemplated hereby, the repayment of the Loans, the expiration or termination
of the Commitments or the termination of this Agreement or any provision hereof.

               SECTION 9.06. Counterparts; Integration; Effectiveness. This
Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of
which when taken together shall constitute a single contract. This Agreement,
the other Loan Documents and any separate letter agreements with respect to the
Borrower's agreement to cooperate with Lucent with respect to marketing, selling
or syndicating Loans and Commitments or with respect to fees payable to Lucent
or either Agent constitute the entire contract among the parties relating to the
subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except
as provided in Section 4.01, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof which, when taken together, bear the
signatures of each of the other parties hereto, and thereafter shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns. Delivery of an executed counterpart of a signature page
of this Agreement by telecopy shall be effective as delivery of a manually
executed counterpart of this Agreement.

               SECTION 9.07. Severability. Any provision of this Agreement held
to be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

               SECTION 9.08. Right of Setoff. If an Event of Default shall have
occurred and be continuing, each Lender and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time


<PAGE>   116
                                                                             110


held and other obligations at any time owing by such Lender or Affiliate to or
for the credit or the account of the Borrower against any of and all the
obligations of the Borrower now or hereafter existing under this Agreement held
by such Lender, irrespective of whether or not such Lender shall have made any
demand under this Agreement and although such obligations may be unmatured. The
rights of each Lender under this Section are in addition to other rights and
remedies (including other rights of setoff) which such Lender may have.

               SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of
Process. (a) This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

               (b) Each of Holdings and the Borrower hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New
York, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to any Loan Document, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement or any other Loan Document shall
affect any right that either Agent or any Lender may otherwise have to bring any
action or proceeding relating to this Agreement or any other Loan Document
against Holdings or the Borrower or its properties in the courts of any
jurisdiction.

               (c) Each of Holdings and the Borrower hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
any other Loan Document in any court referred to in paragraph (b) of this
Section. Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient


<PAGE>   117
                                                                             111


forum to the maintenance of such action or proceeding in any such court.

               (d) Each party to this Agreement irrevocably consents to service
of process in the manner provided for notices in Section 9.01. Nothing in this
Agreement or any other Loan Document will affect the right of any party to this
Agreement to serve process in any other manner permitted by law.

               SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF
OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH
PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY
OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B)
ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS IN THIS SECTION.

               SECTION 9.11. Headings. Article and Section headings and the
Table of Contents used herein are for convenience of reference only, are not
part of this Agreement and shall not affect the construction of, or be taken
into consideration in interpreting, this Agreement.

               SECTION 9.12. Confidentiality. Each of the Agents and the Lenders
agrees to maintain the confidentiality of the Information (as defined below),
except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (b) to the extent requested
by any regulatory authority, (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) to any other party
to this Agreement, (e) in connection with the exercise of any remedies hereunder
or any suit, action or proceeding relating to this Agreement or any other Loan
Document or the enforcement of rights hereunder or thereunder, (f) subject to an
agreement containing provisions


<PAGE>   118
                                                                             112


substantially the same as those of this Section, to any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement, (g) with the consent of the Borrower
or (h) to the extent such Information (i) becomes publicly available other than
as a result of a breach of this Section or (ii) becomes available to either
Agent or any Lender on a nonconfidential basis from a source other than Holdings
or the Borrower. For the purposes of this Section, "Information" means all
information received from Holdings or the Borrower relating to Holdings or the
Borrower or its business, other than any such information that is publicly
available or available to either Agent or any Lender on a nonconfidential basis
prior to disclosure by Holdings or the Borrower. Any Person required to maintain
the confidentiality of Information as provided in this Section shall be
considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such
Information as such Person would accord to its own confidential information.

               SECTION 9.13. Interest Rate Limitation. Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to any Loan,
together with all fees, charges and other amounts which are treated as interest
on such Loan under applicable law (collectively the "Charges"), shall exceed the
maximum lawful rate (the "Maximum Rate") which may be contracted for, charged,
taken, received or reserved by the Lender holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder,
together with all Charges payable in respect thereof, shall be limited to the
Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or periods shall be increased
(but not above the Maximum Rate therefor) until such cumulated amount, together
with interest thereon


<PAGE>   119
                                                                             113


at the Federal Funds Effective Rate to the date of repayment, shall have been
received by such Lender.

               IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed by their respective authorized officers as of the day and
year first above written.

                           WIRELESS COMMUNICATIONS, INC., a Delaware corporation
                           (the "Borrower"), each subsidiary of the Borrower
                           listed on Schedule I hereto (each a "Subsidiary",
                           and, collectively, the "Subsidiaries"), each
                           subsidiary of Leap Wireless International, Inc., a
                           Delaware corporation (the "Parent") listed on
                           Schedule I hereto (each a "License Subsidiary", and,
                           collectively, the "License Subsidiaries"; and
                           together with the Subsidiaries, Holdings and the

                           the "Collateral Agent") for the Secured Parties.


         Reference is made to the Collateral Agency and Intercreditor Agreement
dated as of September 17, 1999 (as amended, supplemented or otherwise modified
from time to time, the "Collateral Agency and Intercreditor Agreement") among
the Borrower, the Representatives and Unrepresented Holders referred to therein
and the Collateral Agent. Capitalized terms used herein and not defined herein
shall have the meanings assigned to such terms in the Collateral Agency and
Intercreditor Agreement. Each Pledgor acknowledges receipt of a true and correct
copy of the Collateral Agency and Intercreditor Agreement and agrees to the
terms thereof.

         The Lenders have agreed to make Loans to the Borrower pursuant to, and
upon the terms and subject to the conditions specified in, the Credit Agreement.
The obligations of the Lenders to make Loans are conditioned upon, among other
things, the execution and delivery by the Pledgors of a Pledge Agreement in the
form hereof. The Borrower may from time to time incur Permitted Additional
Obligations that are required to be secured pursuant to the terms hereof.

         Accordingly, the Pledgors and the Collateral Agent, on behalf of itself
and each Secured Party (and each of their respective successors or assigns),
hereby agree as follows:

         SECTION 1.  Pledge.  As security for the payment and performance, as
the case may be, in full of the Obligations, each Pledgor hereby transfers,
grants, bargains, sells,

                                                                               2



conveys, hypothecates, pledges, sets over and delivers unto the Collateral
Agent, its successors and assigns, and hereby grants to the Collateral Agent,
its successors and assigns, for the ratable benefit of the Secured Parties, a
security interest in all of such Pledgor's right, title and interest in, to and
under (a) all shares of capital stock, membership interests or other equity
interests owned by it, all of which are listed on Schedule II hereto, and any
shares of capital stock, membership interests or other equity interests obtained
in the future by the Pledgor and the certificates representing all such shares,
membership interests or other equity interests (collectively, the "Pledged
Stock"); provided that the pledged interests shall not include to the extent
that applicable law requires that a subsidiary of the Pledgor issue directors'
qualifying shares, such qualifying shares; (b)(i) all debt securities owned by
it, all of which are listed opposite the name of the Pledgor on Schedule II
hereto, (ii) any debt securities in the future issued to the Pledgor and (iii)
the promissory notes and any other instruments evidencing such debt securities
(the "Pledged Debt Securities"); (c) all other property that may be delivered to
and held by the Collateral Agent pursuant to the terms hereof; (d) subject to
Section 5, all payments of principal or interest, dividends, cash, instruments
and other property from time to time received, receivable or otherwise
distributed, in respect of, in exchange for or upon the conversion of the
securities referred to in clauses (a) and (b) above; (e) subject to Section 5,
all rights and privileges of the Pledgor with respect to the securities and
other property referred to in clauses (a), (b), (c) and (d) above; and (f) all
proceeds of any of the foregoing (the items referred to in clauses (a) through
(f) above being collectively referred to as the "Collateral"). Upon delivery to
the Collateral Agent, (a) any stock certificates, notes or other securities now
or hereafter included in the Collateral (the "Pledged Securities") shall be
accompanied by stock powers duly executed in blank or other instruments of
transfer satisfactory to the Collateral Agent and by such other instruments and
documents as the Collateral Agent may reasonably request in order to give effect
to the pledge granted hereby and (b) all other property comprising part of the
Collateral shall be accompanied by proper instruments of assignment duly
executed by the applicable Pledgor and such other instruments or documents as

reasonably request in order to give effect to the pledge granted hereby. Each
delivery of Pledged Securities shall be accompanied by a schedule describing the
securities theretofore and then being pledged hereunder, which schedule shall be
attached hereto as Schedule II and made a part hereof. Each schedule so
delivered shall supersede any prior schedules so delivered.

         TO HAVE AND TO HOLD the Collateral, together with all right, title,
interest, powers, privileges and preferences pertaining or incidental thereto,
unto the Collateral Agent, its successors and assigns, for the ratable benefit
of the Secured Parties, forever; subject, however, to the terms, covenants and
conditions hereinafter set forth.

         SECTION 2. Delivery of the Collateral. (a) Each Pledgor agrees promptly
to deliver or cause to be delivered to the Collateral Agent any and all Pledged
Securities, and any and all certificates or other instruments or documents
representing the Collateral.

         (b) Each Pledgor will cause any Indebtedness for borrowed money owed to

hereby represents, warrants and covenants, as to itself and the Collateral
pledged by it hereunder, to and with the Collateral Agent that as of the
Effective Date:

                  (a) the Pledged Stock represents that percentage as set forth
         on Schedule II of the issued and outstanding shares of each class of
         the capital stock of the issuer with respect thereto;

                  (b) except for the security interest granted hereunder, the
         Pledgor (i) is and will at all times continue to be the direct owner,
         beneficially and of record, of the Pledged Securities indicated on
         Schedule

                                                                               4



         II, (ii) holds the same free and clear of all Liens, (iii) will make no
         assignment, pledge, hypothecation or transfer of, or create or permit
         to exist any security interest in or other Lien on, the Collateral,
         other than pursuant hereto, and (iv) subject to Section 5, will cause
         any and all Collateral, whether for value paid by the Pledgor or
         otherwise, to be forthwith deposited with the Collateral Agent and
         pledged or assigned hereunder;

                  (c) the Pledgor (i) has the power and authority to pledge the
         Collateral in the manner hereby done or contemplated and (ii) will
         defend its title or interest thereto or therein against any and all
         Liens (other than the Lien created by this Agreement), however arising,
         of all Persons whomsoever;

                  (d) except for such consents and approvals as have been
         obtained and are in full force and effect, no consent of any other
         Person (including stockholders or creditors of any Pledgor) and no
         consent or approval of any Governmental Authority or any securities
         exchange was or is necessary to the validity of the pledge effected
         hereby;

                  (e) by virtue of the execution and delivery by the Pledgors of
         this Agreement, when the Pledged Securities, certificates or other
         documents representing or evidencing the Collateral are delivered to,
         and continue to be in the possession of, the Collateral Agent in
         accordance with this Agreement, the Collateral Agent will have a valid
         and perfected first lien upon and security interest in such Pledged
         Securities as security for the payment and performance of the
         Obligations;

                  (f) the pledge effected hereby is effective to vest in the
         Collateral Agent, on behalf of the Secured Parties, the rights of the
         Collateral Agent in the Collateral as set forth herein;

                  (g) all of the Pledged Stock has been duly authorized and
         validly issued and is fully paid and nonassessable;

<PAGE>   5
                                                                               5



                  (h) all information set forth herein relating to the Pledged
         Stock is accurate and complete in all material respects as of the date
         hereof; and

                  (i) the pledge of the Pledged Stock pursuant to this Agreement
         does not violate Regulation U or X of the Federal Reserve Board or any
         successor thereto as of the date hereof.

         SECTION 4. Registration in Nominee Name; Denominations. The Collateral
Agent, on behalf of the Secured Parties, shall have the right (in its sole and
absolute discretion) to hold the Pledged Securities in its own name as pledgee,
the name of its nominee (as pledgee or as sub-agent) or the name of the
Pledgors, endorsed or assigned in blank or in favor of the Collateral Agent.
Each Pledgor will promptly give to the Collateral Agent copies of any material
notices or other communications received by it with respect to Pledged
Securities registered in the name of such Pledgor. The Collateral Agent shall at
all times have the right to exchange the certificates representing Pledged
Securities for certificates of smaller or larger denominations for any purpose
consistent with this Agreement.

         SECTION 5. Voting Rights; Dividends and Interest, etc. (a) Unless a
Notice of Enforcement is in effect:

                  (i) Each Pledgor shall be entitled to exercise any and all
         voting and/or other consensual rights and powers inuring to an owner of
         Pledged Securities or any part thereof for any purpose consistent with
         the terms of this Agreement, the other Support Documents and the
         Secured Instruments; provided, however, that such Pledgor will not be
         entitled to exercise any such right if the result thereof could
         materially and adversely affect the rights inuring to a holder of the
         Pledged Securities or the rights and remedies of any of the Secured
         Parties under this Agreement or any other Support Document or any
         Secured Instrument or the ability of the Secured Parties to exercise
         the same.

                  (ii) The Collateral Agent shall execute and deliver to each
         Pledgor, or cause to be executed and delivered to each Pledgor, all
         such proxies, powers of attorney and other instruments as such Pledgor
         may reasonably request for the purpose of enabling such Pledgor to
         exercise the voting and/or consensual rights and powers it is entitled
         to exercise pursuant to subparagraph (i) above and to receive the cash
         dividends it is entitled to receive pursuant to subparagraph (iii)
         below.

                  (iii) Each Pledgor shall be entitled to receive and retain any
         and all cash dividends, interest and principal paid on the Pledged
         Securities to the extent and only to the extent that such cash
         dividends, interest and principal are permitted by, and otherwise paid
         in accordance with, the terms and conditions of the Support Documents,
         the Secured Instruments and applicable laws. While a Notice of
         Enforcement is in effect, all noncash dividends, interest and
         principal, and all dividends, interest and principal paid or payable in
         cash or otherwise in connection with a partial or total liquidation or
         dissolution, return of capital, capital surplus or paid-in surplus, and
         all other distributions (other than distributions referred to in the
         preceding sentence) made on or in respect of the Pledged Securities,
         whether paid or payable in cash or otherwise, whether resulting from a
         subdivision, combination or reclassification of the outstanding capital
         stock of the issuer of any Pledged Securities or received in exchange
         for Pledged Securities or any part thereof, or in redemption thereof,
         or as a result of any merger, consolidation, acquisition or other
         exchange of assets to which such issuer may be a party or otherwise,
         shall be and become part of the Collateral, and, if received by any
         Pledgor, shall not be commingled by such Pledgor with any of its other
         funds or property but shall be held separate and apart therefrom, shall
         be held in trust for the benefit of the Collateral Agent and shall be
         forthwith delivered to the Collateral Agent in the same form as so
         received (with any necessary endorsement).

         (b) While a Notice of Enforcement is in effect, all rights of any
Pledgor to dividends, interest or principal


<PAGE>   7
                                                                               7



that such Pledgor is authorized to receive pursuant to paragraph (a)(iii) above
shall cease, and all such rights shall thereupon become vested in the Collateral
Agent, which shall have the sole and exclusive right and authority to receive
and retain such dividends, interest or principal. All dividends, interest or
principal received by the Pledgor contrary to the provisions of this Section 5
shall be held in trust for the benefit of the Collateral Agent, shall be
segregated from other property or funds of such Pledgor and shall be forthwith
delivered to the Collateral Agent upon demand in the same form as so received
(with any necessary endorsement). Any and all money and other property paid over
to or received by the Collateral Agent pursuant to the provisions of this
paragraph (b) shall be retained by the Collateral Agent in the Enforcement
Collateral Account upon receipt of such money or other property and shall be
applied in accordance with the provisions of Section 7. After a Notice of
Enforcement has been rescinded in accordance with the terms of the Collateral
Agency and Intercreditor Agreement, the Collateral Agent shall, within five
Business Days after all such Notices of Enforcement have been rescinded, repay
to each Pledgor all cash dividends, interest or principal (without interest),
that such Pledgor would otherwise be permitted to retain pursuant to the terms
of paragraph (a)(iii) above and which remain in the Enforcement Collateral
Account.

         (c) While a Notice of Enforcement is in effect, rights of any Pledgor
to exercise the voting and consensual rights and powers it is entitled to
exercise pursuant to paragraph (a)(i) of this Section 5, and the obligations of
the Collateral Agent under paragraph (a)(ii) of this Section 5, shall cease, and
all such rights shall thereupon become vested in the Collateral Agent, which
shall have the sole and exclusive right and authority to exercise such voting
and consensual rights and powers in a manner not inconsistent with the terms of
this Agreement, provided that, unless otherwise directed by the Required Secured
Parties, the Collateral Agent shall have the right from time to time while a
Notice of Enforcement is in effect to permit the Pledgors to exercise such
rights. After all Notices of Enforcement have been rescinded in accordance with
the terms


<PAGE>   8
                                                                               8



of the Collateral Agency and Intercreditor Agreement, such Pledgor will have the
right to exercise the voting and consensual rights and powers that it would
otherwise be entitled to exercise pursuant to the terms of paragraph (a)(i)
above.

         SECTION 6. Remedies upon Default. While a Notice of Enforcement is in
effect, subject to applicable regulatory and legal requirements, the Collateral
Agent may sell the Collateral, or any part thereof, at public or private sale or
at any broker's board or on any securities exchange, for cash, upon credit or
for future delivery as the Collateral Agent shall deem appropriate subject to
applicable law and standards of commercial reasonableness. The Collateral Agent
shall be authorized at any such sale (if it deems it advisable to do so) to
restrict the prospective bidders or purchasers to Persons who will represent and
agree that they are purchasing the Collateral for their own account for
investment and not with a view to the distribution or sale thereof, and upon
consummation of any such sale the Collateral Agent shall have the right to
assign, transfer and deliver to the purchaser or purchasers thereof the
Collateral so sold. Each such purchaser at any such sale shall hold the property
sold absolutely free from any claim or right on the part of any Pledgor, and, to
the extent permitted by applicable law, the Pledgors hereby waive all rights of
redemption, stay, valuation and appraisal any Pledgor now has or may at any time
in the future have under any rule of law or statute now existing or hereafter
enacted.

         The Collateral Agent shall give a Pledgor 10 days' prior written notice
(which each Pledgor agrees is reasonable notice within the meaning of Section
9-504(3) of the Uniform Commercial Code as in effect in the State of New York or
its equivalent in other jurisdictions) of the Collateral Agent's intention to
make any sale of such Pledgor's Collateral. Such notice, in the case of a public
sale, shall state the time and place for such sale and, in the case of a sale at
a broker's board or on a securities exchange, shall state the board or exchange
at which such sale is to be made and the day on which the Collateral, or portion
thereof, will first be offered for sale at such board or exchange. Any such
public sale shall be held at such time or times within ordinary business hours
and at

<PAGE>   9
                                                                               9



such place or places as the Collateral Agent may fix and state in the notice of
such sale. At any such sale, the Collateral, or portion thereof, to be sold may
be sold in one lot as an entirety or in separate parcels, as the Collateral
Agent may (in its sole and absolute discretion) determine. The Collateral Agent
shall not be obligated to make any sale of any Collateral if it shall determine
not to do so, regardless of the fact that notice of sale of such Collateral
shall have been given. The Collateral Agent may, without notice or publication,
adjourn any public or private sale or cause the same to be adjourned from time
to time by announcement at the time and place fixed for sale, and such sale may,
without further notice, be made at the time and place to which the same was so
adjourned. In case any sale of all or any part of the Collateral is made on
credit or for future delivery, the Collateral so sold may be retained by the
Collateral Agent until the sale price is paid in full by the purchaser or
purchasers thereof, but the Collateral Agent shall not incur any liability in
case any such pur chaser or purchasers shall fail to take up and pay for the
Collateral so sold and, in case of any such failure, such Collateral may be sold
again upon like notice. Subject to Section 9.05 of the Collateral Agency and
Intercreditor Agreement, at any public (or, to the extent permitted by
applicable law, private) sale made pursuant to this Section 6, any Secured Party
may bid for or purchase, free from any right of redemption, stay or appraisal on
the part of any Pledgor (all said rights being also hereby waived and released),
the Collateral or any part thereof offered for sale. For purposes hereof, (a) a
written agreement to purchase the Collateral or any portion thereof shall be
treated as a sale thereof, (b) the Collateral Agent shall be free to carry out
such sale pursuant to such agreement and (c) such Pledgor shall not be entitled
to the return of the Collateral or any portion thereof subject thereto,
notwithstanding the fact that after the Collateral Agent shall have entered into
such an agreement the applicable Notice of Enforcement shall have been rescinded
in accordance with the terms of the Collateral Agency and Intercreditor
Agreement and the Obligations paid in full. As an alternative to exercising the
power of sale herein conferred upon it, the Collateral Agent may proceed by a

                                                                              10



suit or suits at law or in equity to foreclose upon the Collateral and to sell
the Collateral or any portion thereof pursuant to a judgment or decree of a
court or courts having competent jurisdiction or pursuant to a proceeding by a
court-appointed receiver. Any sale pursuant to the provisions of this Section 6
shall be deemed to conform to the commercially reasonable standards as provided
in Section 9-504(3) of the Uniform Commercial Code as in effect in the State of
New York or its equivalent in other jurisdictions.

         SECTION 7. Application of Proceeds of Sale. The proceeds of any sale of
Collateral pursuant to Section 6, as well as any Collateral consisting of cash,
shall be applied promptly by the Collateral Agent after receipt thereof as
provided in the Collateral Agency and Intercreditor Agreement.

         Upon any sale of the Collateral by the Collateral Agent (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the purchase money by the Collateral Agent or of the officer
making the sale shall be a sufficient discharge to the purchaser or purchasers
of the Collateral so sold and such purchaser or purchasers shall not be
obligated to see to the application of any part of the purchase money paid over
to the Collateral Agent or such officer or be answerable in any way for the
misapplication thereof.

         SECTION 8. Reimbursement of Collateral Agent. (a) Each Pledgor agrees
to pay upon demand to the Collateral Agent the amount of any and all reasonable
expenses, including the reasonable fees, other charges and disbursements of its
counsel and of any experts or agents, that the Collateral Agent may incur in
connection with (i) the administration of this Agreement, (ii) the custody or
preservation of, or the sale of, collection from, or other realization upon, any
of the Collateral, (iii) the exercise or enforcement of any of the rights of the
Collateral Agent hereunder or (iv) the failure by such Pledgor to perform or
observe any of the provisions hereof.

                                                                              11



         (b) Without limitation of its indemnification obligations under the
other Support Documents, each Pledgor agrees to indemnify the Collateral Agent
and the other Indemnitees against, and hold each Indemnitee harmless from, any
and all losses, claims, damages, liabilities and related expenses, including
reasonable counsel fees, other charges and disbursements, incurred by or
asserted against any Indemnitee arising out of, in any way connected with, or as
a result of (i) the execution or delivery of this Agreement or any other Support
Document or any agreement or instrument contemplated hereby or thereby, the
performance by the parties hereto of their respective obligations thereunder or
the consummation of the transactions contemplated hereby or (ii) any claim,
litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto, provided that such indemnity
shall not, as to any Indemnitee, be available to the extent that such losses,
claims, damages, liabilities or related expenses have resulted from the gross
negligence or wilful misconduct of such Indemnitee.

         (c) Any amounts payable as provided hereunder shall be additional
Obligations secured hereby and by the other Security Documents. The provisions
of this Section 8 shall remain operative and in full force and effect regardless
of the termination of this Agreement or any other Support Document or any
Secured Instrument, the consummation of the transactions contemplated hereby,
the repayment of any of the Obligations, the invalidity or unenforceability of
any term or provision of this Agreement or any other Support Document or any
Secured Instrument or any investigation made by or on behalf of the Collateral
Agent or any other Secured Party. All amounts due under this Section 8 shall be
payable on written demand therefor and, if not paid within five Business Days
after written demand for payment is received by a Pledgor from the Collateral
Agent, shall bear interest at the rate specified in Section 2.11(c) of the
Credit Agreement.

         (d) To the extent that the Pledgors fail to pay any amount required to
be paid by them to the Collateral Agent under paragraph (a) or (b) of this
Section, each Secured Party severally agrees to pay to the Collateral Agent such
Secured Party's pro rata share (determined as of the time that the applicable
unreimbursed expense or indemnity


<PAGE>   12
                                                                              12



payment is sought) of such unpaid amount; provided that the unreimbursed expense
or indemnified loss, claim, damaged, liability or related expense, as the case
may be, was incurred by or asserted against the Collateral Agent in its capacity
as such. For purposes hereof, a Secured Party's "pro rata share" shall be
determined based upon its share of the sum of the total outstanding loans and
unused commitments under the Secured Instruments at the time.

         SECTION 9. Collateral Agent Appointed Attorney-in-Fact. Each Pledgor
hereby appoints the Collateral Agent, effective while a Notice of Enforcement is
in effect, the attorney-in-fact of such Pledgor for the purpose of carrying out
the provisions of this Agreement and taking any action and executing any
instrument that the Collateral Agent may deem necessary or advisable to
accomplish the purposes hereof, which appointment is irrevocable and coupled
with an interest. Without limiting the generality of the foregoing, the
Collateral Agent shall have the right, while a Notice of Enforcement is in
effect, with full power of substitution either in the Collateral Agent's name or
in the name of such Pledgor, to ask for, demand, sue for, collect, receive and
give acquittance for any and all moneys due or to become due under and by virtue
of any Collateral, to endorse checks, drafts, orders and other instruments for
the payment of money payable to the Pledgor representing any interest or
dividend or other distribution payable in respect of the Collateral or any part
thereof or on account thereof and to give full discharge for the same, to
settle, compromise, prosecute or defend any action, claim or proceeding with
respect thereto, and to sell, assign, endorse, pledge, transfer and to make any
agreement respecting, or otherwise deal with, the same, in each case in a manner
not inconsistent with the terms of this Agreement; provided, however, that
nothing herein contained shall be construed as requiring or obligating the
Collateral Agent to make any commitment or to make any inquiry as to the nature
or sufficiency of any payment received by the Collateral Agent, or to present or
file any claim or notice, or to take any action with respect to the Collateral
or any part thereof or the moneys due or to become due in respect thereof or any
property covered


<PAGE>   13
                                                                              13



thereby. The Collateral Agent and the other Secured Parties shall be accountable
only for amounts actually received as a result of the exercise of the powers
granted to them herein, and neither they nor their officers, directors,
employees or agents shall be responsible to any Pledgor for any act or failure
to act hereunder, except for their own gross negligence or wilful misconduct.

         SECTION 10. Waivers; Amendment. (a) No failure or delay of the
Collateral Agent in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Collateral Agent hereunder
and of the Collateral Agent and the other Secured Parties under the other
Support Documents and the Secured Instruments are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provisions of this Agreement or consent to any departure by any Pledgor
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) below, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. No notice or demand
on any Pledgor in any case shall entitle such Pledgor to any other or further
notice or demand in similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to a written agreement entered into between
the Collateral Agent and the Pledgor or Pledgors with respect to which such
waiver, amendment or modification is to apply, subject to any consent required
in accordance with Section 11.02 of the Collateral Agency and Intercreditor
Agreement.

         SECTION 11. Securities Act, etc. In view of the position of the
Pledgors in relation to the Pledged Securities, or because of other current or
future circumstances, a question may arise under the Securities Act of 1933, as
now or hereafter in effect, or any similar statute hereafter enacted analogous
in purpose or effect (such Act and any such similar statute as from time to time
in effect being called the "Federal Securities Laws") with


<PAGE>   14
                                                                              14



respect to any disposition of the Pledged Securities permitted hereunder. Each
Pledgor understands that compliance with the Federal Securities Laws might very
strictly limit the course of conduct of the Collateral Agent if the Collateral
Agent were to attempt to dispose of all or any part of the Pledged Securities,
and might also limit the extent to which or the manner in which any subsequent
transferee of any Pledged Securities could dispose of the same. Similarly, there
may be other legal restrictions or limitations affecting the Collateral Agent in
any attempt to dispose of all or part of the Pledged Securities under applicable
Blue Sky or other state securities laws or similar laws analogous in purpose or
effect. Each Pledgor recognizes that in light of such restrictions and
limitations the Collateral Agent may, with respect to any sale of the Pledged
Securities, limit the purchasers to those who will agree, among other things, to
acquire such Pledged Securities for their own account, for investment, and not
with a view to the distribution or resale thereof. Each Pledgor acknowledges and
agrees that in light of such restrictions and limitations, the Collateral Agent,
in its sole and absolute discretion, (a) may proceed to make such a sale whether
or not a registration statement for the purpose of registering such Pledged
Securities or part thereof shall have been filed under the Federal Securities
Laws and (b) may approach and negotiate with a single potential purchaser to
effect such sale. Each Pledgor acknowledges and agrees that any such sale might
result in prices and other terms less favorable to the seller than if such sale
were a public sale without such restrictions. In the event of any such sale, the
Collateral Agent shall incur no responsibility or liability for selling all or
any part of the Pledged Securities at a price that the Collateral Agent, in its
sole and absolute discretion, may in good faith deem reasonable under the
circumstances, notwithstanding the possibility that a substantially higher price
might have been realized if the sale were deferred until after registration as
aforesaid or if more than a single purchaser were approached. The provisions of
this Section 11 will apply notwithstanding the existence of a public or private
market upon which the quotations or sales prices may exceed substantially the
price at which the Collateral Agent sells.

         SECTION 12. Security Interest Absolute. All rights of the Collateral
Agent hereunder, the grant of a security interest in the Collateral and all
obligations of each Pledgor hereunder, shall be absolute and unconditional
irrespective of (a) any lack of validity or enforceability of any Support
Document or Secured Instrument, any agreement with respect to any of the
Obligations or any other agreement or instrument relating to any of the
foregoing, (b) any change in the time, manner or place of payment of, or in any
other term of, all or any of the Obligations, or any other amendment or waiver
of or any consent to any departure from any Support Document or Secured
Instrument or any other agreement or instrument relating to any of the
foregoing, (c) any exchange, release or nonperfection of any other collateral,
or any release or amendment or waiver of or consent to or departure from any
guaranty, for all or any of the Obligations or (d) any other circumstance that
might otherwise constitute a defense available to, or a discharge of, any
Pledgor in respect of the Obligations or in respect of this Agreement (other
than the indefeasible payment in full of all the Obligations).

         SECTION 13. Termination or Release. (a) This Agreement and the security
interests granted hereby shall terminate when all the Obligations have been
indefeasibly paid in full and all Secured Instrument Commitments shall have
terminated.

         (b) Subject to Section 9.03 of the Collateral Agency and Intercreditor
Agreement, upon any sale or other transfer by any Pledgor of any Collateral that
does not violate any Secured Instrument to any Person that is not a Pledgor, the
security interest in such Collateral shall be automatically released.

         (c) In connection with any termination or release pursuant to paragraph
(a) or (b), the Collateral Agent shall execute and deliver to any Pledgor, at
such Pledgor's expense, all documents that such Pledgor shall reasonably request
to evidence such termination or release. Any execution and delivery of documents
pursuant to this Section 13 shall be without recourse to or warranty by the
Collateral Agent.

                                                                              16



         SECTION 14. Notices. All communications and notices hereunder shall be
in writing and given as provided in Section 11.01 of the Collateral Agency and
Intercreditor Agreement. All communications and notices hereunder to any
Subsidiary Loan Party shall be given to it in care of the Borrower at the
address set forth in the Credit Agreement.

         SECTION 15. Further Assurances. Each Pledgor agrees to do such further
acts and things, and to execute and deliver such additional conveyances,
assignments, agreements and instruments, as the Collateral Agent may at any time
reasonably request in connection with the administration and enforcement of this
Agreement or with respect to the Collateral or any part thereof or in order
better to assure and confirm unto the Collateral Agent its rights and remedies
hereunder.

         SECTION 16. Binding Effect; Several Agreement; Assignments. Whenever in
this Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party; and all covenants,
promises and agreements by or on behalf of any Pledgor that are contained in
this Agreement shall bind and inure to the benefit of its successors and
assigns. This Agreement shall become effective as to any Pledgor when a
counterpart hereof executed on behalf of such Pledgor shall have been delivered
to the Collateral Agent and a counterpart hereof shall have been executed on
behalf of the Collateral Agent, and thereafter shall be binding upon such
Pledgor and the Collateral Agent and their respective successors and assigns,
and shall inure to the benefit of such Pledgor, the Collateral Agent and the
other Secured Parties, and their respective successors and assigns, except that
no Pledgor shall have the right to assign its rights hereunder or any interest
herein or in the Collateral (and any such attempted assignment shall be void),
except as expressly contemplated by this Agreement or the other Support
Documents. Subject to Section 9.03 of the Collateral Agency and Intercreditor
Agreement, if all of the capital stock of a Pledgor is sold, transferred or
otherwise disposed of to a Person that is not a Pledgor pursuant to a
transaction that does not violate any Secured Instrument, such Pledgor shall be
released from its obligations under this Agreement without further action. This
Agreement shall be construed as a separate agreement with respect to each



<PAGE>   17
                                                                              17



Pledgor and may be amended, modified, supplemented, waived or released with
respect to any Pledgor without the approval of any other Pledgor and without
affecting the obligations of any other Pledgor hereunder.

         SECTION 17. Survival of Agreement; Severability. (a) All covenants,
agreements, representations and warranties made by each Pledgor herein and in
the certificates or other instruments prepared or delivered in connection with
or pursuant to this Agreement or any other Support Document shall be considered
to have been relied upon by the Collateral Agent and the other Secured Parties
and shall survive the extension of credit by any Secured Party pursuant to a
Secured Instrument, regardless of any investigation made by the Secured Parties
or on their behalf, and shall continue in full force and effect until this
Agreement shall terminate.

         (b) In the event any one or more of the provisions contained in this
Agreement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby (it being understood
that the invalidity of a particular provision in a particular jurisdiction shall
not in and of itself affect the validity of such provision in any other
jurisdiction). The parties shall endeavor in good-faith negotiations to replace
the invalid, illegal or unenforceable provisions with valid provisions the
economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

         SECTION 18. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         SECTION 19. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute a single contract, and shall become effective
as provided in Section 16. Delivery of an executed counterpart of a signature
page to this Agreement


<PAGE>   18
                                                                              18



by facsimile transmission shall be as effective as delivery of a manually
executed counterpart of this Agreement.

         SECTION 20. Rules of Interpretation. The rules of interpretation
specified in Section 1.02 of the Collateral Agency and Intercreditor Agreement
shall be applicable to this Agreement. Section headings used herein are for
convenience of reference only, are not part of this Agreement and are not to
affect the construction of, or to be taken into consideration in interpreting
this Agreement.

         SECTION 21. Jurisdiction; Consent to Service of Process. (a) Each
Pledgor hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of the Supreme Court of the State of
New York sitting in New York County and of the United States District Court of
the Southern District of New York, and any appellate court from any thereof, in
any action or proceeding arising out of or relating to this Agreement or any
other Support Document, or for recognition or enforcement of any judgment, and
each of the parties hereto hereby irrevocably and unconditionally agrees that
all claims in respect of any such action or proceeding may be heard and
determined in such New York State or, to the extent permitted by law, in such
Federal court. Each of the parties hereto agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement or any other Support Document shall affect any right
that the Collateral Agent or any other Secured Party may otherwise have to bring
any action or proceeding relating to this Agreement or any other Loan Document
against any Pledgor or its properties in the courts of any jurisdiction.

         (b) Each Pledgor hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection that it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or any other Support Document in
any New York State or Federal court. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

                                                                              19



         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 14. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 22. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT
NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

         SECTION 23. Additional Pledgors. Upon execution and delivery by the
Collateral Agent and a Subsidiary Loan Party of an instrument in the form of
Annex 1, such Subsidiary Loan Party shall become a Pledgor hereunder with the
same force and effect as if originally named as a Pledgor herein. The execution
and delivery of such instrument shall not require the consent of any Pledgor
hereunder. The rights and obligations of each Pledgor hereunder shall remain in
full force and effect notwithstanding the addition of any new Pledgor as a party
to this Agreement. This Agreement may be waived, amended or modified with
respect to any one or more Pledgors and any one or more Pledgors may be released
from its obligations hereunder without the consent or agreement of any other
Pledgor.

         SECTION 24. Execution of Financing Statements. Pursuant to Section
9-402 of the Uniform Commercial Code as in effect in the State of New York, each
Pledgor authorizes the Collateral Agent to file financing statements with
respect to the Collateral owned by it without the signature of such Pledgor in
such form and in such filing offices as the Collateral Agent reasonably
determines appropriate to perfect the security interests of the Collateral Agent
under this Agreement. A carbon, photographic or other

reproduction of this Agreement shall be sufficient as a financing statement for
filing in any jurisdiction.

         IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the day and year first above written.

obtain a judgment and to enforce such judgment, in each case to the same extent
as if such Secured Party were an unsecured creditor.


                                   ARTICLE IV

                           Duties of Collateral Agent

        SECTION 4.01. Notice to Secured Parties. The Collateral Agent shall
promptly notify each Representative and Unrepresented Holder in the event it
shall receive any Notice of Enforcement or any Notice of Cancelation of
Enforcement or any request by any party hereto or by any Loan Party for any
consent, waiver or amendment with respect hereto or any other Support Document.

        SECTION 4.02. Actions Under Support Documents. The Collateral Agent
shall not be obligated to take any action under this Agreement or any of the
Support Documents except for the performance of such duties as are specifically
set forth herein or therein. Subject to the provisions of Article VII, the
Collateral Agent shall take any action under or with respect to the Support
Documents which is requested by the Required Committed Secured Parties (or, at
any time when a Notice of Enforcement is in effect, the Required Secured
Parties) and which is not inconsistent with or contrary to the provisions of
this Agreement or any other Support Document. At any time when a Notice of
Enforcement shall be in effect, the Collateral Agent shall, subject in all cases
to the provisions of Article VII, exercise or refrain from exercising all such
rights, powers


<PAGE>   24
                                       24


and remedies as shall be available to it under the Support Documents or any of
them in accordance with any written instructions received from the Required
Secured Parties. Absent written instructions from the Required Secured Parties
at a time when a Notice of Enforcement shall be in effect, the Collateral Agent
may take, but shall have no obligation to take, any and all such actions under
the Support Documents or any of them or otherwise as it shall deem to be in the
best interests of the Secured Parties in order to maintain the Collateral and
protect and preserve the Collateral and the rights of the Secured Parties.

        SECTION 4.03. Records. The Collateral Agent shall maintain records
regarding determinations of the amounts of the outstanding Obligations and
Secured Instrument Commitments for any purpose, any distributions from the
Collateral Accounts and any information received by the Collateral Agent
pursuant to Section 6.02. The information contained in such records shall be
made available to any Secured Party upon request.


                                    ARTICLE V

                       Collateral Accounts; Distributions

        SECTION 5.01. The Collateral Accounts. (a) The Collateral Agent shall
establish and maintain at its office located at [ ] three collateral accounts
designated the "Enforcement Collateral Account", the "Subordination Collateral
Account" and the "General Collateral Account", respectively (such collateral
accounts, collectively, the "Collateral Accounts").

        (b) All amounts which are received by the Collateral Agent (in its
capacity as Collateral Agent) in respect of the Collateral, whether in
connection with the exercise of any right or remedy provided in this Agreement
or any other Support Document or otherwise (including all amounts received on
account of any sale of or other


<PAGE>   25
                                       25


realization upon any of the Collateral pursuant to any Security Document), or
pursuant to enforcement of the Guarantee Agreement, in each case while a Notice
of Enforcement is in effect shall be deposited in the Enforcement Collateral
Account. While a Notice of Enforcement is in effect, all amounts on deposit in
or required to be deposited in the Subordination Collateral Account or the
General Collateral Account shall be transferred to the Enforcement Collateral
Account. Upon the rescission of each effective Notice of Enforcement in
accordance with the terms hereof, the Collateral Agent shall (subject to the
payment of any Obligations then due in accordance with Section 5.02) release any
funds then remaining on deposit in the Enforcement Collateral Account to any
Loan Party to the extent required by any of the Security Documents; provided
that such funds in an amount equal to the sum of (x) the amount of General Funds
transferred to the Enforcement Collateral Account from the General Collateral
Account pursuant to paragraph (d) of this Section and (y) the amount of funds
that would have been deposited in the General Collateral Account pursuant to
paragraph (d) of this Section if a Notice of Enforcement had not been in effect,
together with all interest and income on such amounts, shall be deposited in the
General Collateral Account for application in accordance with the terms of
paragraph (d) of this Section.

        (c) All amounts which are received by the Collateral Agent (in its
capacity as Collateral Agent) pursuant to terms of the Subordination Agreement
shall be deposited in the Subordination Collateral Account. While a Notice of
Enforcement is in effect, all amounts on deposit in or required to be deposited
in the Subordination Collateral Account shall be transferred to the Enforcement
Collateral Account.

        (d) All amounts which are received by the Collateral Agent (in its
capacity as Collateral Agent) which by the terms of any Support Document or any
Secured Instrument are required to be held by the Collateral Agent (other than
amounts required to be deposited in the Enforcement Collateral Account or the
Subordination Collateral Account) shall be deposited in the General


<PAGE>   26
                                       26


Collateral Account. While a Notice of Enforcement is in effect, all amounts on
deposit in or required to be deposited in the General Collateral Account shall
be transferred to the Enforcement Collateral Account. The Borrower may, by
delivery to the Collateral Agent of a General Funds Release Request, request a
release of General Funds from the General Collateral Account in accordance with
the applicable provisions of the Support Document or Secured Instrument or
Secured Instruments which required such funds to be deposited with the
Collateral Agent (but only to the extent any funds in the General Collateral
Account were deposited in the General Collateral Account pursuant to such
agreements). If no Notice of Enforcement is in effect on the date on which such
General Funds are requested to be released pursuant to the applicable General
Funds Release Request, the Collateral Agent shall release such General Funds in
accordance with such General Funds Release Request. Pending the receipt by the
Collateral Agent of a General Funds Release Request with respect to any General
Funds or a transfer of such General Funds to the Enforcement Collateral Account
as provided above, the Collateral Agent shall invest such funds in Permitted
Investments (and the proceeds thereof and interest thereon shall constitute part
of such General Funds).

        (e) All amounts deposited in the Collateral Accounts shall be held by
the Collateral Agent subject to the terms hereof and of the Support Documents
and shall constitute Collateral under the Security Agreement. No Loan Party
shall have any rights with respect to, and the Collateral Agent shall have
exclusive dominion and control over, the Collateral Accounts.

        SECTION 5.02. Application of Proceeds. Subject to Section 5.05, all
amounts deposited in the Enforcement Collateral Account shall be applied in the
following order of priority:

        FIRST, to the payment of all costs and expenses incurred by the
Collateral Agent (in its capacity as such


<PAGE>   27
                                       27


hereunder or any other Support Document) in connection with any Support Document
or any of the Obligations, including all court costs and the fees and expenses
of its agents and legal counsel, the repayment of all advances made by the
Collateral Agent under any Support Document on behalf of any Loan Party and any
other costs and expenses incurred in connection with the exercise of any right
or remedy hereunder or under any other Support Document;

        SECOND, to the Secured Parties pro rata in accordance with the aggregate
amounts of the Obligations outstanding on the date of any such distribution
(whether or not due and payable); and

        THIRD, the balance, if any, to the Borrower or its successors and
assigns, or such other Person or Persons as shall be entitled thereto, or as a
court of competent jurisdiction may otherwise direct.

        SECTION 5.03. Time of Payments. Subject to any written instructions
received by the Collateral Agent from the Required Secured Parties as to the
times at which any amounts are to be distributed pursuant to Section 5.02, all
distributions under Section 5.02 shall be made at such times as the Collateral
Agent shall, in its sole discretion, determine, subject to Section 5.04.

        SECTION 5.04. Application of Amounts Not Distributable. If any
Representative or Unrepresented Holder shall inform the Collateral Agent in
writing that no provision is made under the relevant Secured Instrument for the
application of amounts which are to be distributed in respect of Obligations
under such Secured Instrument pursuant to Section 5.02 (whether by virtue of the
applicable Obligations thereunder not being then due and payable or otherwise)
or for the holding of such amounts by or on behalf of such parties pending
application thereof, then the Collateral Agent shall invest such amounts in
Permitted Investments and shall hold such amounts and all proceeds thereof in
the Enforcement Collateral Account, solely for the Secured Parties represented
by such Representative or such Unrepresented Holder, as the case may be, until
such Representative or Unrepresented Holder shall


<PAGE>   28
                                       28


notify the Collateral Agent that such Obligations have been paid (in which case
such amounts and all proceeds thereof shall be applied in accordance with the
provisions of Section 5.02) or shall request the delivery thereof by the
Collateral Agent for application pursuant to such Secured Instrument.

        SECTION 5.05. Treatment of Contingent Obligations. Notwithstanding the
foregoing, distributions under clause SECOND of Section 5.02 shall be made
disregarding any Contingent Obligations. If any Contingent Obligations exist at
any time that any amounts are to be distributed to the Borrower under clause
THIRD of Section 5.02, the Collateral Agent shall deposit such amounts up to an
amount equal to such Contingent Obligations in a collateral account established
and maintained at its office located at [ ] (designated the "Contingent
Obligations Collateral Account") for the benefit of the Secured Parties that
have a claim with respect to such Contingent Obligations. The Collateral Agent
shall invest such amounts in Permitted Investments until the Representative of
such Secured Parties or the applicable Unrepresented Holder, as the case may be,
shall notify the Collateral Agent that any or all of the Contingent Obligations
with respect to the Secured Parties represented by such Representative or such
Unrepresented Holder, as the case may be, have become fixed or liquidated (in
which case such amounts up to the amount in the Contingent Obligations
Collateral Account shall be delivered to such Representative or Unrepresented
Holder, as the case may be, to be applied pursuant to the applicable Secured
Instrument) or that such Contingent Obligations have expired or cease to exist
(in which case an amount in the Contingent Obligations Collateral Account in
excess of the Contingent Obligations outstanding at such time shall be applied
in accordance with the provisions of Section 5.02).

        SECTION 5.06. Collateral Agent's Calculations. In making the
determinations and allocations required by Section 5.02, the Collateral Agent
may rely upon


<PAGE>   29
                                       29


certificates as provided in Section 3.02, as to the amounts payable with respect
to Obligations. If any Secured Party receives any amount pursuant to Section
5.02 in excess of the amount it was entitled to receive pursuant to Section 5.02
as a result of a demonstrable error in the determination of the amount of the
Obligations, then such Secured Party (by becoming a Holder of Obligations and
accepting the benefits of this Agreement) agrees to pay such excess to the
Collateral Agent for application in accordance with Section 5.02 as soon as
practicable after the existence of such error shall have been determined. All
distributions made by the Collateral Agent pursuant to Section 5.02 shall be
(subject to the preceding sentence and to any decree of any court of competent
jurisdiction and to the preceding sentence) final, and the Collateral Agent
shall have no duty to inquire as to the application by any Representative or
Unrepresented Holder of any amounts distributed to them.


                                   ARTICLE VI

                                   Agreements

        SECTION 6.01. Delivery of Agreements. The Borrower shall deliver to the
Collateral Agent, promptly upon the execution thereof, true and complete copies
of (a) all amendments, supplements or other modifications to any Secured
Instrument and (b) each Additional Security Document.

        SECTION 6.02. Information. On a quarterly basis promptly following the
end of each calendar quarter, and from time to time upon the request of the
Collateral Agent (which request may be made by the Collateral Agent at the
reasonable direction of any Secured Party), the Borrower shall promptly deliver
to the Collateral Agent a list, setting forth as of a specified date not more
than 10 days prior to the date of delivery, of the aggregate outstanding
Obligations and Secured Instrument Commitments and the name and address of each
Secured Party (and the name and address of such Secured Party's Representative,
if any) and the respective amounts of Obligations and Secured Instrument
Commitments attributable to each. The Collateral Agent


<PAGE>   30
                                       30


shall provide a copy of the most recent list delivered to it under this Section
to any Secured Party upon request.

                                   ARTICLE VII

                              The Collateral Agent

        SECTION 7.01. Appointment; Rights and Duties. (a) Each of the Secured
Parties hereby irrevocably appoints the Collateral Agent as its agent and
authorizes the Collateral Agent to take such actions on its behalf and to
exercise such powers as are delegated to the Collateral Agent by the terms of
the Support Documents, together with such actions and powers as are reasonably
incidental thereto.

        (b) Any Person serving as the Collateral Agent hereunder shall have the
same rights and powers in its capacity as a Secured Party as any other Secured
Party and may exercise the same as though it were not the Collateral Agent, and
such Person and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrower or any Subsidiary or
other Affiliate thereof as if it were not the Collateral Agent hereunder.

        (c) The Collateral Agent shall not have any duties or obligations except
those expressly set forth in the Support Documents. Without limiting the
generality of the foregoing, (i) the Collateral Agent shall not be subject to
any fiduciary or other implied duties, regardless of whether a Notice of
Enforcement is in effect, (ii) the Collateral Agent shall not have any duty to
take any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated by the Support Documents
that the Collateral Agent is required to exercise in writing by the Required
Secured Parties, and (iii) except as expressly set forth in the Support
Documents, the Collateral Agent shall not have


<PAGE>   31
                                       31


any duty to disclose, and shall not be liable for the failure to disclose, any
information relating to the Parent, the Borrower or the Subsidiary Loan Parties
that is communicated to or obtained by the Person serving as the Collateral
Agent or any of its Affiliates in any capacity. The Collateral Agent shall not
be liable for any action taken or not taken by it with the consent or at the
request of the Secured Parties (or the requisite portion thereof as required by
any applicable provision of this Agreement) or in the absence of its own gross
negligence or wilful mis conduct. The Collateral Agent shall be deemed not to
have knowledge of any event that could result in a Notice of Enforcement unless
and until a Notice of Enforcement is given to the Collateral Agent, and the
Collateral Agent shall not be responsible for or have any duty to ascertain or
inquire into (A) any statement, warranty or representation made in or in
connection with any Support Document or Secured Instrument, (B) the contents of
any certificate, report or other document delivered thereunder or in connection
therewith, (C) the performance or observance of any of the covenants, agreements
or other terms or conditions set forth in any Support Document or Secured
Instrument, (D) the validity, enforceability, effectiveness or genuineness of
any Support Document or Secured Instrument or any other agreement, instrument or
document, or (E) the satisfaction of any condition set forth in any Support
Document or Secured Instrument, other than to confirm receipt of items expressly
required to be delivered to the Collateral Agent.

        (d) The Collateral Agent shall be entitled to rely upon, and shall not
incur any liability for relying upon, any notice, request, certificate, consent,
statement, instrument, document or other writing believed by it to be genuine
and to have been signed or sent by the proper Person. The Collateral Agent also
may rely upon any statement made to it orally or by telephone and believed by it
to be made by the proper Person, and shall not incur any liability for relying
thereon. The Collateral Agent may consult with legal counsel (who may be counsel
for the


<PAGE>   32
                                       32


Parent or the Borrower), independent accountants and other experts selected by
it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountants or experts.

        (e) The Collateral Agent may perform any and all its duties and exercise
its rights and powers by or through any one or more sub-agents appointed by the
Collateral Agent. The Collateral Agent and any such sub-agent may perform any
and all its duties and exercise its rights and powers through their respective
Related Parties. The exculpatory provisions of the preceding paragraphs shall
apply to any such sub-agent and to the Related Parties of the Collateral Agent
and any such sub-agent, and shall apply to their respective activities in
connection with the activities as Collateral Agent.

        (f) Subject to the appointment and acceptance of a successor Collateral
Agent as provided in this paragraph, the Collateral Agent may resign at any time
by notifying each Secured Party and the Borrower. Upon any such resignation, the
Required Committed Secured Parties (or, at any time when a Notice of Enforcement
is in effect, the Required Secured Parties) shall have the right to appoint a
successor. If no successor shall have been so appointed by the Required
Committed Secured Parties (or, if applicable, the Required Secured Parties) and
shall have accepted such appointment within 30 days after the retiring
Collateral Agent gives notice of its resignation, then the retiring Collateral
Agent may, on behalf of the Secured Parties, appoint a successor Collateral
Agent which shall be a bank with an office in New York, New York or an Affiliate
of any such bank. Upon the acceptance of its appointment as Collateral Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Collateral Agent,
and the retiring Collateral Agent shall be discharged from its duties and
obligations hereunder. The fees payable by the Borrower to a successor
Collateral Agent shall be the same as those payable to its predecessor unless
otherwise agreed between the Borrower and such successor. After the Collateral
Agent's resignation hereunder, the provisions of this Article shall continue in
effect for the benefit of


<PAGE>   33
                                       33


such retiring Collateral Agent, its sub-agents and their respective Related
Parties in respect of any actions taken or omitted to be taken by any of them
while it was acting as Collateral Agent.

        (g) Each Secured Party acknowledges that it has, independently and
without reliance upon the Collateral Agent or any other Secured Party and based
on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to extend credit to the Borrower pursuant to the
applicable Secured Instrument and enter into this Agreement. Each Secured Party
also acknowledges that it will, independently and without reliance upon the
Collateral Agent or any other Secured Party and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any other Support Document or related agreement or any document furnished
hereunder or thereunder.

        SECTION 7.02. Expenses; Indemnity; Damage Waiver. (a) The Borrower shall
pay (i) all costs and expenses incurred by the Collateral Agent, including the
fees, charges and disbursements of counsel for the Collateral Agent, in
connection with the negotiation, preparation, execution and delivery of the
Support Documents, and (ii) all costs and expenses incurred by the Collateral
Agent, including the fees, charges and disbursements of any counsel, consultants
or appraisers for the Collateral Agent, in connection with (A) the enforcement
or protection of its rights in connection with the Support Documents, including
its rights under this Section and (B) the administration of, and any amendments,
modifications, waivers or supplements of or to the provisions of, any of the
Support Documents.

        (b) The Borrower shall indemnify the Collateral Agent and each of its
Related Parties (each such Person being called an "Indemnitee") against, and
hold each Indemnitee harmless from, any and all losses, claims,


<PAGE>   34
                                       34


damages, liabilities and related expenses, including the fees, charges and
disbursements of any counsel for any Indemnitee, incurred by or asserted against
any Indemnitee arising out of, in connection with, or as a result of (i) the
execution or delivery of any Support Document or Secured Instrument or any other
agreement or instrument contemplated hereby, or the performance by the parties
to the Support Documents or Secured Instruments of their respective obligations
thereunder, (ii) any extension of credit under any Secured Instrument or the use
of the proceeds therefrom, (iii) any actual or alleged presence or release of
Hazardous Materials on or from any property owned or operated by the Borrower or
any of the Subsidiary Loan Parties or at which any Collateral is located, or any
Environmental Liability related in any way to the Borrower or any of the
Subsidiary Loan Parties, or (iv) any actual or prospective claim, litigation,
investigation or proceeding relating to any of the foregoing, whether based on
contract, tort or any other theory and regardless of whether any Indemnitee is a
party thereto; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses have resulted from the gross negligence or wilful misconduct of
such Indemnitee.

        (c) To the extent permitted by applicable law, the Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement or any agreement or instrument contemplated hereby.

        (d) All amounts due under this Section shall be payable not later than
30 days after written demand therefor.

                                  ARTICLE VIII

                         Representations and Warranties

                  The Borrower represents and warrants to the


<PAGE>   35
                                       35

Secured Parties that:

        SECTION 8.01. Organization; Powers. Each Loan Party is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization, has all requisite power and authority to carry on its business as
now conducted and, except where the failure to do so, individually or in the
aggregate, could not reasonably be expected to result in a material adverse
effect of the Borrower and the Subsidiary Loan Parties taken as a whole, is
qualified to do business in, and is in good standing in, every jurisdiction
where such qualification is required.

        SECTION 8.02. Authorization; Enforceability. The execution delivery and
performance by each Loan Party of the Support Documents to which it is a party
are within such Loan Party's corporate powers and have been duly authorized by
all necessary company or corporate, as the case may be, and, if required,
stockholder action. This Agreement and each other Support Document has been duly
executed and delivered by each Loan Party that is a party thereto and
constitutes a legal, valid and binding obligation of such Loan Party (as the
case may be), enforceable in accordance with its terms, subject to applicable
bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors' rights generally and subject to general principles of equity,
regardless of whether considered in a proceeding in equity or at law.

        SECTION 8.03. Governmental Approvals; No Conflicts. The execution,
delivery and performance by each Loan Party of the Support Documents to which it
is a party (a) do not require any consent or approval of, registration or filing
with, or any other action by, any Governmental Authority, except such as have
been obtained or made and are in full force and effect and except filings
necessary to perfect Liens created under the Security Documents, (b) will not
violate any applicable law or regulation or the charter, by-laws or other
organizational documents of any Loan Party


<PAGE>   36
                                       36


or any order of any Governmental Authority, (c) will not violate or result in a
default under any indenture, agreement or other instrument binding upon any Loan
Party or its assets, or give rise to a right thereunder to require any payment
to be made by any Loan Party, and (d) will not result in the creation or
imposition of any Lien on any asset of any Loan Party, except Liens created
under the Security Documents.

                                   ARTICLE IX

                           Intercreditor Arrangements

        SECTION 9.01. Security Interests. The Collateral Agent and each of the
Secured Parties hereby agree that the Liens and security interests granted to
the Collateral Agent under the Security Documents, and the Guarantees provided
under the Guarantee Agreement, shall be treated, as among the Secured Parties,
as having equal priority and shall at all times be shared by the Secured Parties
as provided herein.

        SECTION 9.02. Turnover of Collateral and Certain Payments. If any
Secured Party (i) acquires custody, control or possession of any Collateral or
proceeds therefrom or (ii) receives any payment pursuant to enforcement of the
Guarantee Agreement, in each case other than pursuant to the terms of this
Agreement, then such Secured Party shall promptly cause such Collateral,
proceeds or payments to be delivered to or put in the custody, possession or
control of the Collateral Agent for disposition or distribution in accordance
with the provisions of Article V. Until such time as the provisions of the
immediately preceding sentence have been complied with, such Secured Party shall
be deemed to hold such Collateral, proceeds or payments in trust for the parties
entitled thereto hereunder. Notwithstanding the foregoing, no Secured Party
shall be required to deliver to or put in the custody, possession or control of
the Collateral Agent


<PAGE>   37
                                       37


or to hold in trust as specified in the preceding sentence any amount of any
Obligation paid or prepaid by the Borrower to it (and not obtained by it through
any sale of or other realization upon any Collateral or by enforcement of its
rights under the Guarantee Agreement as provided herein and in the Support
Documents) in accordance with the terms of the applicable Secured Instrument.

        SECTION 9.03. Release of Collateral and Guarantees. (a) In connection
with any sale, transfer or disposition of any Collateral to any Person other
than the Borrower or any Subsidiary Loan Party that does not violate any Secured
Instrument, the Secured Parties agree that any Liens on such Collateral created
pursuant to the Security Documents will be released upon the delivery of
evidence satisfactory to the Collateral Agent that such sale, transfer or
disposition (and the release of such Liens and, if applicable, any guarantee of
the Obligations) is in compliance with the requirements of each Secured
Instrument (including a certificate from a Financial Officer to such effect). In
the event any such sale, transfer or disposition to a Person other than the
Parent or any subsidiary thereof (including the Borrower or any Subsidiary Loan
Party) shall be of 100% of the Equity Interests of a Subsidiary Loan Party, the
Secured Parties hereby authorize the Collateral Agent upon the delivery of such
evidence to release such Subsidiary and its assets from its obligations under
and the Liens created by the Support Documents and to execute amendments,
releases and other documents in form and substance satisfactory to the
Collateral Agent confirming such release.

        (b) Collateral may be released in connection with the exercise of any
rights, powers or remedies by the Collateral Agent pursuant to and in accordance
with Section 4.02 and such release shall not require any approval under this
Section.

        (c) The Secured Parties hereby authorize the Collateral Agent to execute
releases and other documents in form and substance satisfactory to the
Collateral Agent in respect of any release of Collateral permitted under this
Section.


<PAGE>   38
                                       38


        SECTION 9.04. Additional Collateral. Each of the Secured Parties hereby
covenants and agrees that it (a) will not accept any Guarantee of any of the
Obligations by any Person unless such Person's Guarantee is provided pursuant to
the Guarantee Agreement or otherwise Guarantees the payment of all the
Obligations on a pari passu basis and (b) will not take any security interest in
or Lien on or assignment of any assets to secure any of the Obligations unless
such security interest or Lien or assignment is granted to the Collateral Agent
to secure the payment of all the Obligations on a pari passu basis pursuant to
an Additional Security Document; provided that the foregoing shall not apply to
any insurance or other credit support acquired by a Secured Party at its own
expense from a Person (other than any Loan Party or an Affiliate thereof) with
respect to the Obligations.

        SECTION 9.05. Purchase of Collateral. Any Secured Party may purchase
Collateral at any public sale of such Collateral pursuant to any of the Security
Documents and to the extent, but only to the extent, approved by the Required
Secured Parties (determined for this purpose without giving effect to the
Obligations owed to the Secured Party that is making such purchase, unless it is
the only Holder at the time) may make payment on account thereof by using any
Obligation then due and payable to such Secured Party from the Person which

                              Benefit of Agreement

        This Agreement is being executed and delivered by the Persons whose
names appear on the signature pages below and by such other Persons as become
parties hereto by the execution and delivery of a Permitted Additional
Obligations Designation pursuant to Section 2.01, but shall benefit, in addition
to such Persons, each other Secured Party represented by a Representative
(including the Lenders). Notwithstanding the foregoing, it is expressly
understood that the entitlement of each such other Secured Party to the benefits
of this Agreement and of the Support Documents is subject to the terms and
conditions of this Agreement and is expressly conditioned on the observance by
such Secured Party of such terms and conditions. Without limiting the foregoing,
the Collateral Agent may (but shall not be required to), as a condition to
making any distribution hereunder to which any such Secured Party would be
entitled, require that such Secured Party execute and deliver to the Collateral
Agent an acknowledgment of and consent to all the provisions of this Agreement
(specifically including the provisions of Section 5.06); provided that the
failure to request or obtain any such acknowledgment or consent shall not affect
any of the obligations of such Secured Party hereunder.

                                  Miscellaneous

        SECTION 11.01. Notices. Except in the case of notices and other

                                       40


follows:

                (a) if to the Borrower, to it at 10307 Pacific Center Court, San
        Diego, California 92121, Attention of President (Telecopy No. (619)
        882-6010);

                (b) if to the Collateral Agent, to it at [ ], Attention of [ ]
        (Telecopy No. [ ]);

                (c) if to the Administrative Agent, to it at 283 King George
        Road, Warren, New Jersey 07059, Attention of Assistant Treasurer-Project

        Obligation Designation.

Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

        SECTION 11.02. Waivers; Amendments. (a) No failure or delay by the
Collateral Agent in exercising any right or power hereunder or under any other
Support Document shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Collateral Agent hereunder and under the other Support
Documents are cumulative and are not exclusive of any rights or remedies that it
would otherwise have. No waiver of any provision of any Support Document or
consent to any departure by any Loan Party therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section,
and then such waiver or


<PAGE>   41
                                       41


consent shall be effective only in the specific instance and for the purpose for

        (b) Neither this Agreement nor any other Support Document nor any
provision hereof or thereof may be waived, amended or modified except, in the
case of this Agreement, pursuant to an agreement or agreements in writing
entered into by the Borrower and the Representatives and/or Unrepresented
Holders representing the Required Committed Secured Parties (or, at any time
when a Notice of Enforcement is in effect, the Required Secured Parties) or, in
the case of any other Support Document, pursuant to an agreement or agreements
in writing entered into by the Collateral Agent and the Loan Party or Loan
Parties that are parties thereto with the consent of the Required Committed
Secured Parties (or, at any time when a Notice of Enforcement is in effect, the
Required Secured Parties); provided that no such agreement shall (i) adversely
affect any of the Collateral Agent's rights, immunities or rights to
indemnification hereunder or under any Support Document or expand its duties
hereunder or under any Support Document, without the prior written consent of
the Collateral Agent, (ii) modify any provision hereof which is intended to
provide for the equal and ratable security of all Obligations without the prior
written consent of all Secured Parties, (iii) release all or any substantial
part of the Collateral from the Liens of the Security Documents (except as
expressly provided in Section 9.03), without the prior written consent of each
Secured Party, (iv) release any Subsidiary Loan Party from its Guarantee under
the Guarantee Agreement (except as expressly provided in Section 9.03) or limit
or condition its obligations thereunder, without the prior written consent of
each Secured Party, or (v) change the definitions of "Credit Facility
Obligations", "Obligations", "Permitted Additional Obligations", "Required
Secured Parties", "Required Committed Secured Parties" or this Section or
Section 9.03 without the prior written consent of each Secured Party.
Notwithstanding the foregoing, the Collateral Agent and the Borrower and, in the
case of the Guarantee Agreement, any


<PAGE>   42
                                       42


guarantor party to the Guarantee Agreement, may enter into one or more
agreements supplemental to the applicable Support Documents, in form and
substance satisfactory to the Collateral Agent, to add any guarantor of the
Obligations or any grantor to any Security Document.

        SECTION 11.03. Counterparts. This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original, but all of which when taken together
shall constitute a single contract. Delivery of an executed counterpart of a
signature page of this Agreement by telecopy shall be effective as delivery of a
manually executed counterpart of this Agreement.

        SECTION 11.04. Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

        SECTION 11.05. Governing Law; Jurisdiction; Consent to Service of
Process. (a) This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

        (b) The Borrower hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to any
Support Document, or for recognition or enforcement of any judgment, and each of
the parties hereto hereby irrevocably and unconditionally agrees that all claims
in respect of any such action or proceeding may be heard and determined in such
New York State or, to the extent permitted by law, in such Federal court. Each
of the parties hereto agrees that


<PAGE>   43
                                       43


a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement or any other Support Document shall
affect any right that the Collateral Agent or any Secured Party may otherwise
have to bring any action or proceeding relating to this Agreement or any other
Support Document against the Borrower or their properties in the courts of any
jurisdiction.

        (c) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or any other Support Document in
any court referred to in paragraph (b) of this Section. Each of the parties
hereto hereby irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court.

        (d) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 11.01. Nothing in this
Agreement or any other Support Document will affect the right of any party to
this Agreement to serve process in any other manner permitted by law.

        SECTION 11.06. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR ANY OTHER SUPPORT DOCUMENT (WHETHER BASED ON
CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY
OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK
TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER
PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER



<PAGE>   44

affect the construction of, or be taken into consideration in interpreting, this
Agreement.

        SECTION 11.08. Successors and Assigns. (a) Whenever in this Agreement
any of the parties hereto is referred to, such reference shall be deemed to
include the successors and assigns of such party (including, in the case of any
Secured Party, each transferee or assignee of Obligations held by it).

        (b) The Borrower shall not assign or delegate any of its rights or
duties hereunder or any of its interest herein without the prior written consent
of each Secured Party, and any purported assignment or delegation in
contravention of this paragraph shall be void.

        SECTION 11.09. Termination. This Agreement shall automatically terminate
when (i) the Liens and security interests granted under the Security Documents
have terminated and (ii) the Collateral has been released and the Obligations
have been indefeasibly paid and performed in full and all Secured Instrument
Commitments shall have terminated; provided that the provisions of Section 7.02
shall not be affected by any such termination.

        SECTION 11.10. Complete Agreement. This Agreement constitutes the entire
agreement between the parties hereto with respect to the subject matter hereof
and supersedes all prior representations, negotiations, writings, memoranda and
agreements.

                                                                       EXHIBIT C

                        GUARANTEE AGREEMENT dated as of September 17, 1999,
                among CRICKET COMMUNICATIONS, INC., a Delaware corporation
                ("Holdings"), each of the subsidiaries of Cricket Wireless
                Communications, Inc., a Delaware corporation (the "Borrower")
                listed on Schedule I hereto (each such subsidiary individually,
                a "Subsidiary" and, collectively, the "Subsidiaries"), each of
                the subsidiaries of Leap Wireless International, Inc., a
                Delaware corporation (the "Parent") listed on Schedule I hereto
                (each such subsidiary individually, a "License Subsidiary" and,
                collectively, the "License Subsidiaries"; and Holdings, each
                Subsidiary and License Subsidiary, individually, a "Guarantor"
                and, collectively, the "Guarantors") and STATE STREET BANK AND
                TRUST COMPANY, as collateral agent (in such capacity, the
                "Collateral Agent"), for the Secured Parties.

        Reference is made to the Collateral Agency and Intercreditor Agreement
dated as of September 17, 1999 (as amended, supplemented or otherwise modified
from time to time, the "Collateral Agency and Intercreditor Agreement") among
the Borrower, the Representatives and Unrepresented Holders referred to therein
and the Collateral Agent. Capitalized terms used herein and not defined herein
shall have the meanings assigned to such terms in the Collateral Agency and
Intercreditor Agreement. Each Guarantor acknowledges receipt of a true and
correct copy of the Collateral Agency and Intercreditor Agreement and agrees to
the terms thereof.

        The Lenders have agreed to make Loans to the Borrower pursuant to, and
upon the terms and subject to the conditions specified in, the Credit Agreement.
Each of the Guarantors is a direct or indirect subsidiary of the Borrower or the
Parent and acknowledges that it will derive substantial benefit from the making
of the Loans by the Lenders. The obligations of the Lenders to make Loans are
conditioned on, among other things, the execution and delivery by the Guarantors
of a Guarantee Agreement in the form hereof. As consideration therefor and in
order to induce the Lenders to make Loans, the Guarantors are willing to execute
this Agreement. The Borrower may from time to time incur Permitted Additional
Obligations that are required to be guaranteed pursuant to the terms hereof.


<PAGE>   2
                                       2


        Accordingly, the parties hereto agree as follows:

        SECTION 1. Guarantee. Each Guarantor unconditionally guarantees, jointly
with the other Guarantors and severally, as a primary obligor and not merely as
a surety, the due and punctual payment of the Obligations, when and as due,
whether at maturity, by acceleration, upon one or more dates set for prepayment
or otherwise. Each Guarantor further agrees that the Obligations may be extended
or renewed, in whole or in part, without notice to or further assent from it,
and that it will remain bound upon its guarantee notwithstanding any extension
or renewal of any Obligation.

        Anything contained in this Agreement to the contrary notwithstanding,
the obligations of each Guarantor hereunder shall be limited to a maximum
aggregate amount equal to the greatest amount that would not render such
Guarantor's obligations hereunder subject to avoidance as a fraudulent transfer
or conveyance under Section 548 of Title 11 of the United States Code or any
provisions of applicable state law (collectively, the "Fraudulent Transfer
Laws"), in each case after giving effect to all other liabilities of such
Guarantor, contingent or otherwise, that are relevant under the Fraudulent
Transfer Laws (specifically excluding, however, any liabilities of such
Guarantor (a) in respect of intercompany indebtedness to the Borrower or
Affiliates of the Borrower to the extent that such indebtedness would be
discharged in an amount equal to the amount paid by such Guarantor hereunder and
(b) under any Guarantee of senior unsecured indebtedness or Indebtedness
subordinated in right of payment to the Obligations which Guarantee contains a
limitation as to maximum amount similar to that set forth in this paragraph,
pursuant to which the liability of such Guarantor hereunder is included in the
liabilities taken into account in determining such maximum amount) and after
giving effect as assets to the value (as determined under the applicable
provisions of the Fraudulent Transfer Laws) of any rights to subrogation,
contribution, reimbursement, indemnity or similar rights of such Guarantor
pursuant to (i) applicable law or (ii) any agreement providing for an equitable
allocation among such Guarantor and other Affiliates of the Borrower of
obligations arising under Guarantees by such parties (including the Indemnity,
Subrogation and Contribution Agreement).


<PAGE>   3
                                       3


        SECTION 2. Obligations Not Waived. To the fullest extent permitted by
applicable law, each Guarantor waives presentment to, demand of payment from and
protest to the Borrower of any of the Obligations, and also waives notice of
acceptance of its guarantee and notice of protest for nonpayment. To the fullest
extent permitted by applicable law, the obligations of each Guarantor hereunder
shall not be affected by (a) the failure of the Collateral Agent or any other
Secured Party to assert any claim or demand or to enforce or exercise any right
or remedy against the Borrower or any other Guarantor under the provisions of
any Support Document or Secured Instrument or otherwise, (b) any rescission,
waiver, amendment or modification of, or any release from any of the terms or
provisions of this Agreement, any other Support Document, any Secured
Instrument, any Guarantee or any other agreement, including with respect to any
other Guarantor under this Agreement or (c) the failure to perfect any security
interest in, or the release of, any of the security held by or on behalf of the
Collateral Agent or any other Secured Party.

        SECTION 3. Security. Each of the Guarantors authorizes the Collateral
Agent and each of the other Secured Parties, to (a) take and hold security for
the payment of this Guarantee and the Obligations and exchange, enforce, waive
and release any such security, (b) apply such security and direct the order or
manner of sale thereof as they in their sole discretion may determine and (c)
release or substitute any one or more endorsees or other guarantors or other
obligors.

        SECTION 4. Guarantee of Payment. Each Guarantor further agrees that its
guarantee hereunder constitutes a guarantee of payment when due and not of
collection, and waives any right to require that any resort be had by the
Collateral Agent or any other Secured Party to any of the security held for
payment of the Obligations or to any balance of any deposit account or credit on
the books of the Collateral Agent or any other Secured Party in favor of the
Borrower or any other Person.

        SECTION 5. No Discharge or Diminishment of Guarantee. The obligations of
each Guarantor hereunder shall not be subject to any reduction, limitation,
impairment or termination for any reason (other than the indefeasible


<PAGE>   4
                                       4


payment in full in cash of all the Obligations), including any claim of waiver,
release, surrender, alteration or compromise of any of the Obligations, and
shall not be subject to any defense or setoff, counterclaim, recoupment or
termination whatsoever by reason of the invalidity, illegality or
unenforceability of the Obligations or otherwise. Without limiting the
generality of the foregoing, the obligations of each Guarantor hereunder shall
not be discharged or impaired or otherwise affected by the failure of the
Collateral Agent or any other Secured Party to assert any claim or demand or to
enforce any remedy under any Support Document, any Secured Instrument or any
other agreement, by any waiver or modification of any provision of any thereof,
by any default, failure or delay, wilful or otherwise, in the performance of the
Obligations, or the failure to perfect any security interest in, or the release
of, any of the security held by or on behalf of the Collateral Agent or any
other Secured Party, or by any other act or omission that may or might in any
manner or to any extent vary the risk of any Guarantor or that would otherwise
operate as a discharge of each Guarantor as a matter of law or equity (other
than the indefeasible payment in full in cash of all the Obligations).

        SECTION 6. Defenses of Borrower Waived. To the fullest extent permitted
by applicable law, each of the Guarantors waives any defense based on or arising
out of any defense of the Borrower or the unenforceability of the Obligations or
any part thereof from any cause, or the cessation from any cause of the
liability of the Borrower, other than the final and indefeasible payment in full
in cash of all the Obligations. The Collateral Agent and the other Secured
Parties may, at their election, foreclose on any security held by one or more of
them by one or more judicial or nonjudicial sales, accept an assignment of any
such security in lieu of foreclosure, compromise or adjust any part of the
Obligations, make any other accommodation with the Borrower or any other
guarantor or exercise any other right or remedy available to them against the
Borrower or any other guarantor, without affecting or impairing in any way the
liability of any Guarantor hereunder except to the extent the Obligations have
been fully, finally and


<PAGE>   5
                                       5


indefeasibly paid in cash. To the fullest extent permitted by applicable law,
each of the Guarantors waives any defense arising out of any such election even
though such election operates, pursuant to applicable law, to impair or to
extinguish any right of reimbursement or subrogation or other right or remedy of
such Guarantor against the Borrower or any other Guarantor or guarantor, as the
case may be, or any security.

        SECTION 7. Agreement to Pay; Subordination. In furtherance of the
foregoing and not in limitation of any other right that the Collateral Agent or
any other Secured Party has at law or in equity against any Guarantor by virtue
hereof, upon the failure of the Borrower or any other Loan Party to pay any
Obligation when and as the same shall become due, whether at maturity, by
acceleration, after notice of prepayment or otherwise, each Guarantor hereby
promises to and will forthwith pay, or cause to be paid, to the Collateral Agent
in cash the amount of such unpaid Obligations to be applied by the Collateral
Agent in the manner required by Article V of the Collateral Agency and
Intercreditor Agreement. Upon payment by any Guarantor of any sums to the
Collateral Agent, all rights of such Guarantor against the Borrower arising as a
result thereof by way of right of subrogation, contribution, reimbursement,
indemnity or otherwise shall in all respects be subordinate and junior in right
of payment to the prior indefeasible payment in full in cash of all the
Obligations as provided in the Subordination Agreement.

        SECTION 8. Information. Each of the Guarantors assumes all
responsibility for being and keeping itself informed of the Borrower's financial
condition and assets, and of all other circumstances bearing upon the risk of
nonpayment of the Obligations and the nature, scope and extent of the risks that
such Guarantor assumes and incurs hereunder, and agrees that none of the
Collateral Agent or the other Secured Parties will have any duty to advise any
of the Guarantors of information known to it or any of them regarding such
circumstances or risks.

        SECTION 9. Representations and Warranties. Each of


<PAGE>   6
                                       6


the Guarantors represents and warrants as to itself that all representations and
warranties relating to it contained in the Credit Agreement are true and
correct.

        SECTION 10. Termination. The Guarantees made hereunder (a) shall
terminate when all the Obligations have been indefeasibly paid in full and all
Secured Instrument Commitments shall have been terminated and (b) shall continue
to be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of any Obligation is rescinded or must otherwise be restored
by any Secured Party or any Guarantor upon the bankruptcy or reorganization of
the Borrower, any Guarantor or otherwise.

        SECTION 11. Binding Effect; Several Agreement; Assignments. Whenever in
this Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party; and all covenants,
promises and agreements by or on behalf of the Guarantors that are contained in
this Agreement shall bind and inure to the benefit of each party hereto and
their respective successors and assigns. This Agreement shall become effective
as to any Guarantor when a counterpart hereof executed on behalf of such
Guarantor shall have been delivered to the Collateral Agent, and a counterpart
hereof shall have been executed on behalf of the Collateral Agent, and
thereafter shall be binding upon such Guarantor and the Collateral Agent and
their respective successors and assigns, and shall inure to the benefit of such
Guarantor, the Collateral Agent and the other Secured Parties, and their
respective successors and assigns, except that no Guarantor shall have the right
to assign its rights or obligations hereunder or any interest herein (and any
such attempted assignment shall be void). Subject to Section 9.03 of the
Collateral Agency and Intercreditor Agreement, if all of the Equity Interests of
a Guarantor are sold, transferred or otherwise disposed of (other than to the
Parent or an Affiliate thereof including the Borrower or any Subsidiary Loan
Party) pursuant to a transaction that does not violate any Secured Instrument,
such Guarantor shall be released from its obligations under this Agreement
without further action. This Agreement shall be construed as a separate
agreement with respect to each Guarantor and may be amended, modified,
supplemented, waived or released with respect to any Guarantor without the
approval of any


<PAGE>   7
                                       7


other Guarantor and without affecting the obligations of any other Guarantor
hereunder.

        SECTION 12. Waivers; Amendment. (a) No failure or delay of the
Collateral Agent in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Collateral Agent hereunder
and of the Collateral Agent and the other Secured Parties under the other
Support Documents are cumulative and are not exclusive of any rights or remedies
that they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by any Guarantor therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) below, and then
such waiver or consent shall be effective only in the specific instance and for
the purpose for which given. No notice or demand on any Guarantor in any case
shall entitle such Guarantor to any other or further notice or demand in similar
or other circumstances.

        (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to a written agreement entered into between
the Guarantors with respect to which such waiver, amendment or modification
relates and the Collateral Agent, subject to any consents required in accordance
with Section 11.02 of the Collateral Agency and Intercreditor Agreement.

        SECTION 13. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

        SECTION 14. Notices. All communications and notices hereunder shall be
in writing and given as provided in Section 11.01 of the Collateral Agency and
Intercreditor Agreement. All communications and notices hereunder to each
Guarantor shall be given to it in care of the Borrower at the address set forth
in the Credit Agreement.

        SECTION 15. Survival of Agreement; Severability. (a) All covenants,
agreements, representations and warranties made by the Guarantors herein and in
the certificates or other instruments prepared or delivered in connection with
or pursuant to this Agreement or any other Support Document shall be considered
to have been relied upon by the Collateral Agent and the other Secured Parties
and shall survive the extension of credit by any Secured Party pursuant to a
Secured Instrument regardless of any investigation made by any Secured Party or
on their behalf, and shall continue in full force and effect until this
Agreement shall terminate.

        (b) In the event any one or more of the provisions contained in this
Agreement or in any other Support Document should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein and therein shall not in any way be
affected or impaired thereby (it being understood that the invalidity of a
particular provision in a particular jurisdiction shall not in and of itself
affect the validity of such provision in any other jurisdiction). The parties
shall endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

        SECTION 16. Counterparts. This Agreement may be executed in
counterparts, each of which shall constitute an original, but all of which when
taken together shall constitute a single contract, and shall become effective as
provided in Section 11. Delivery of an executed signature page to this Agreement
by facsimile transmission shall be as effective as delivery of a manually
executed counterpart of this Agreement.

        SECTION 17. Rules of Interpretation. The rules of interpretation
specified in Section 1.02 of the Collateral Agency and Intercreditor Agreement
shall be applicable to this Agreement.

        SECTION 18. Jurisdiction; Consent to Service of Process. (a) Each
Guarantor hereby irrevocably and


<PAGE>   9
                                       9


unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New
York, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to this Agreement or any other Support Document, or
for recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement or any other
Support Document shall affect any right that the Collateral Agent or any other
Secured Party may otherwise have to bring any action or proceeding relating to
this Agreement or any other Support Document against any Guarantor or its
properties in the courts of any jurisdiction.

        (b) Each Guarantor hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection that it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or any other Support Document in
any New York State or Federal court. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

        (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 14. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

        SECTION 19. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE


<PAGE>   10
                                       10


LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS
AGREEMENT OR THE OTHER SUPPORT DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT
NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND
THE OTHER SUPPORT DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION 19.

        SECTION 20. Additional Guarantors. Upon execution and delivery after the
date hereof by the Collateral Agent and a Subsidiary Loan Party of an instrument
in the form of Annex 1, such Subsidiary Loan Party shall become a Guarantor
hereunder with the same force and effect as if originally named as a Guarantor
herein. The execution and delivery of any instrument adding an additional
Guarantor as a party to this Agreement shall not require the consent of any
other Guarantor hereunder. The rights and obligations of each Guarantor
hereunder shall remain in full force and effect notwithstanding the addition of
any new Guarantor as a party to this Agreement. This Agreement may be waived,
amended or modified with respect to any one or more Guarantors and any one or
more Guarantors may be released from its obligations hereunder without the
consent or agreement of any other Guarantor.

        SECTION 21. Right of Setoff. While a Notice of Enforcement is in effect,
each Secured Party is hereby authorized at any time and from time to time, to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other Indebtedness at any time owing by such Secured Party to or for the credit
or the account of any Guarantor against any or all the obligations of such
Guarantor now or hereafter existing under this Agreement and the other Support
Documents held by such Secured Party, irrespective of whether or not such
Secured Party shall have made any demand under this Agreement or any other
Support Document and although such obligations may be unmatured. After any
exercise of such right of setoff, the


<PAGE>   11
                                       11


Secured Party shall give notice of such exercise to the Collateral Agent and the
Borrower; provided, however, that failure to give such notice shall not in any
way affect the rights of any Secured Party. The rights of each Secured Party
under this Section 21 are in addition to other rights and remedies (including
other rights of setoff) which such Secured Party may have.

        SECTION 22. Credit Agreement Covenants. Each Guarantor hereby covenants
and agrees to comply with all covenants contained in the Credit Agreement that
are applicable to such Guarantor.

        IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement
as of the day and year first above written.

                                                             Guarantee Agreement

        SUPPLEMENT NO. [ ] dated as of , to the Guarantee Agreement dated as of

induce the Secured Parties to make loans under the Secured Instruments. Section
20 of the Guarantee Agreement provides that additional Subsidiary Loan Parties
may become Guarantors under the Guarantee Agreement by execution and delivery of

provisions of the Guarantee Agreement applicable to it as a Guarantor thereunder
and (b) represents and warrants that the representations and warranties made by
it as a Guarantor thereunder are true and correct on and as of the date hereof

be deemed to include the New Guarantor. The Guarantee Agreement is hereby
incorporated herein by reference.

                                       15


        SECTION 2. The New Guarantor represents and warrants to the Collateral
Agent and the other Secured Parties that this Supplement has been duly
authorized, executed and delivered by it and constitutes its legal, valid and
binding obligation, enforceable against it in accordance with its terms, subject
to applicable bankruptcy, insolvency, moratorium or other laws affecting
creditors' rights generally and subject to general principles of equity
regardless of whether considered in a proceeding in equity or at law.

        SECTION 3. This Supplement may be executed in counterparts, each of

constitute a single contract. This Supplement shall become effective when the
Collateral Agent shall have received counterparts of this Supplement that, when
taken together, bear the signatures of the New Guarantor and the Collateral
Agent. Delivery of an executed signature page to this Supplement by facsimile
transmission shall be as effective as delivery of a manually executed
counterpart of this Supplement.

        SECTION 4. Except as expressly supplemented hereby, the Guarantee
Agreement shall remain in full force and effect.

        SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

        SECTION 6. In case any one or more of the provisions contained in this
Supplement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein and in the Guarantee Agreement shall not in any way be affected or
impaired thereby (it being understood that the invalidity of a particular
provision hereof in a particular jurisdiction shall not in and of itself affect
the validity of such provision in any other jurisdiction). The parties hereto
shall endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

        SECTION 7. All communications and notices hereunder shall be in writing
and given as provided in Section 14 of the Guarantee Agreement. All
communications and notices hereunder to the New Guarantor shall be given to it
at the address set forth under its signature below, with a copy to the Borrower.

                                                                       EXHIBIT D

                        INDEMNITY, SUBROGATION and CONTRIBUTION AGREEMENT dated
                as of September 17, 1999, among CRICKET WIRELESS COMMUNICATIONS,
                INC., a Delaware corporation (the "Borrower"), each subsidiary
                of the Borrower listed on Schedule I hereto (each a
                "Subsidiary", and, collectively, the "Subsidiaries") each
                subsidiary of Leap Wireless International, Inc., a Delaware
                corporation (the "Parent") listed on Schedule I hereto (each a
                "License Subsidiary", and, collectively, the "License
                Subsidiaries"; each such Subsidiary and each such License
                Subsidiary individually, a "Guarantor" and, collectively, the
                "Guarantors") and STATE STREET BANK AND TRUST COMPANY, as
                collateral agent (in such capacity, the "Collateral Agent") for
                the Secured Parties.

        Reference is made to (a) the Collateral Agency and Intercreditor
Agreement dated as of September 17, 1999 (as amended, supplemented or otherwise
modified from time to time, the "Collateral Agency and Intercreditor Agreement")
among the Borrower, the Representatives and Unrepresented Holders referred to
therein and the Collateral Agent and (b) the Guarantee Agreement and the other
Support Documents. Capitalized terms used herein and not defined herein shall
have the meanings assigned to such terms in the Collateral Agency and
Intercreditor Agreement. Each Guarantor acknowledges receipt of a true and
correct copy of the Collateral Agency and Intercreditor Agreement and agrees to
the terms thereof.

        The Lenders have agreed to make Loans to the Borrower pursuant to, and
upon the terms and subject to the conditions specified in, the Credit Agreement.
The Guarantors have guaranteed such Loans and the other Obligations pursuant to
the Guarantee Agreement; certain Guarantors have granted Liens on and security
interests in certain of their assets to secure the Obligations pursuant to the
Security Documents. The obligations of the Lenders to make Loans are conditioned
on, among other things, the execution and delivery by the Borrower, the
Guarantors and the Collateral Agent of an agreement in the form hereof.

                                       2


The Borrower may from time to time incur Permitted Additional Obligations that
are required to be guaranteed pursuant to the Guarantee Agreement and secured
under the Security Documents.

        Accordingly, the Borrower, each Guarantor and the Collateral Agent agree
as follows:

        SECTION 1. Indemnity and Subrogation. In addition to all such rights of
indemnity and subrogation as the Guarantors may have under applicable law (but
subject to Section 3), the Borrower agrees that (a) in the event a payment shall
be made by any Guarantor under the Guarantee Agreement, the Borrower shall
indemnify such Guarantor for the full amount of such payment and such Guarantor
shall be subrogated to the rights of the Person to whom such payment shall have
been made to the extent of such payment and (b) in the event any assets of any
Guarantor shall be sold pursuant to any Security Document to satisfy a claim of
any Secured Party, the Borrower shall indemnify such Guarantor in an amount
equal to the greater of the book value or the fair market value of the assets so
sold.

        SECTION 2. Contribution and Subrogation. Each Guarantor (a "Contributing
Guarantor") agrees (subject to Section 3) that, in the event a payment shall be
made by any other Guarantor under the Guarantee Agreement or assets of any other
Guarantor shall be sold pursuant to any Security Document to satisfy a claim of
any Secured Party and such other Guarantor (the "Claiming Guarantor") shall not
have been fully indemnified by the Borrower as provided in Section 1, the
Contributing Guarantor shall indemnify the Claiming Guarantor in an amount equal
to the amount of such payment or the greater of the book value or the fair
market value of such assets, as the case may be, in each case multiplied by a
fraction of which the numerator shall be the net worth of the Contributing
Guarantor on the date hereof and the denominator shall be the aggregate net
worth of all the Guarantors on the date hereof (or, in the case of any Guarantor
becoming a party hereto pursuant to Section 12, the date of the Supplement
hereto executed and delivered by such Guarantor). Any Contributing Guarantor
making any payment to a Claiming Guarantor pursuant to this Section 2 shall be
subrogated to the rights of such Claiming Guarantor under Section 1 to the
extent of such payment.

        SECTION 3. Subordination. Notwithstanding any provision of this
Agreement to the contrary, all rights of the Guarantors under Sections 1 and 2
and all other rights of indemnity, contribution or subrogation under applicable
law or otherwise shall be fully subordinated to the indefeasible payment in full
in cash of all Obligations which are then due and payable whether at maturity,
by acceleration or otherwise. No failure on the part of the Borrower or any
Guarantor to make the payments required by Sections 1 and 2 (or any other
payments required under applicable law or otherwise) shall in any respect limit
the obligations and liabilities of any Guarantor with respect to its obligations
hereunder, and each Guarantor shall remain liable for the full amount of the
obligations of such Guarantor hereunder.

        SECTION 4. Termination. This Agreement shall survive and be in full
force and effect so long as any Obligation is outstanding and has not been
indefeasibly paid in full in cash, and so long as any of the Secured Instrument
Commitments have not been terminated, and shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
any Obligation is rescinded or must otherwise be restored by any Secured Party
or any Guarantor upon the bankruptcy or reorganization of the Borrower, any
Guarantor or otherwise.

        SECTION 5. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

        SECTION 6. No Waiver; Amendment. (a) No failure on the part of the
Collateral Agent or any Guarantor to exercise, and no delay in exercising, any
right, power or remedy hereunder shall operate as a waiver thereof, nor shall
any single or partial exercise of any such right, power or remedy by the
Collateral Agent or any Guarantor preclude any other or further exercise thereof
or the exercise of any other right, power or remedy. All remedies hereunder are
cumulative and are not exclusive of any other remedies provided by law. None of
the Collateral Agent and the Guarantors shall be deemed to have waived any
rights hereunder unless such waiver shall be in writing and signed by such
parties.

                                       4


        (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to a written agreement entered into between
the Borrower, the Guarantor or Guarantors with respect to which such waiver,
amendment or modification is to apply and the Collateral Agent, subject to any
consents required in accordance with Section 11.02 of the Collateral Agency and
Intercreditor Agreement.

        SECTION 7. Notices. All communications and notices hereunder shall be in
writing and given as provided in the Guarantee Agreement and addressed as
specified therein.

        SECTION 8. Binding Agreement; Assignments. Whenever in this Agreement
any of the parties hereto is referred to, such reference shall be deemed to
include the successors and assigns of such party; and all covenants, promises
and agreements by or on behalf of the parties that are contained in this
Agreement shall bind and inure to the benefit of their respective successors and
assigns. Neither the Borrower nor any Guarantor may assign or transfer any of
its rights or obligations hereunder (and any such attempted assignment or
transfer shall be void), except as expressly contemplated by this Agreement or
the other Support Documents. Notwithstanding the foregoing, at the time any
Guarantor is released from its obligations under the Guarantee Agreement and any
Security Documents to which it is a party in accordance with the Support
Documents and the Secured Instruments, such Guarantor will cease to have any
rights or obligations under this Agreement.

        SECTION 9. Survival of Agreement; Severability. (a) All covenants and
agreements made by the Borrower and each Guarantor herein and in the
certificates or other instruments prepared or delivered in connection with this
Agreement or the other Support Documents shall be considered to have been relied
upon by the Collateral Agent, the other Secured Parties and each Guarantor and
shall survive the extension of credit by any Secured Party pursuant to the
Secured Instruments and shall continue in full force and effect until this
agreement shall terminate.

        (b) In case any one or more of the provisions contained in this
Agreement should be held invalid, illegal


<PAGE>   5
                                       5


or unenforceable in any respect, no party hereto shall be required to comply
with such provision for so long as such provision is held to be invalid, illegal
or unenforceable, but the validity, legality and enforceability of the remaining
provisions contained herein shall not in any way be affected or impaired
thereby. The parties shall endeavor in good-faith negotiations to replace the
invalid, illegal or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

        SECTION 10. Counterparts. This Agreement may be executed in counterparts
(and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract. This Agreement shall be effective with respect to any Guarantor
when a counterpart bearing the signature of such Guarantor shall have been
delivered to the Collateral Agent. Delivery of an executed signature page to
this Agreement by facsimile transmission shall be as effective as delivery of a
manually signed counterpart of this Agreement.

        SECTION 11. Rules of Interpretation. The rules of interpretation
specified in Section 1.02 of the Collateral Agency and Intercreditor Agreement
shall be applicable to this Agreement.

        SECTION 12. Additional Guarantors. Upon execution and delivery, after
the date hereof, by the Collateral Agent and a Subsidiary Loan Party of an
instrument in the form of Annex 1 hereto, such Subsidiary Loan Party shall
become a Guarantor hereunder with the same force and effect as if originally
named as a Guarantor hereunder. The execution and delivery of any instrument
adding an additional Guarantor as a party to this Agreement shall not require
the consent of any Guarantor hereunder. The rights and obligations of each
Guarantor hereunder shall remain in full force and effect notwithstanding the
addition of any new Guarantor as a party to this Agreement. This Agreement may
be waived, amended or modified with respect to any one or more Guarantors and
any one or more Guarantors may be released from its obligations hereunder
without the consent or agreement of any other Guarantor.

Agreement by execution and delivery of an instrument in the form of this
Supplement. The undersigned Subsidiary Loan Party of the Borrower (the "New
Guarantor") is executing this Supplement in accordance with the requirements of
the Credit Agreement to become a Guarantor under the Indemnity, Subrogation and

        Accordingly, the Collateral Agent and the New Guarantor agree as
follows:

        SECTION 1. In accordance with Section 12 of the Indemnity, Subrogation

same force and effect as if originally named therein as a Guarantor and the New
Guarantor hereby agrees to all the terms and provisions of the Indemnity,
Subrogation and Contribution Agreement applicable to it as a Guarantor
thereunder. Each reference to a "Guarantor" in the Indemnity, Subrogation and
Contribution Agreement shall be deemed to include the New Guarantor. The

together, bear the signatures of the New Guarantor and the Collateral Agent.

transmission shall be as effective as delivery of a manually signed counterpart
of this Supplement.

as such provision is held to be invalid, illegal or unenforceable, but the
validity, legality and enforceability of the remaining provisions contained
herein and in the Indemnity, Subrogation and Contribution Agreement shall not in
any way be affected or impaired. The parties hereto shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that

                                                                       EXHIBIT E

                        PARENT AGREEMENT dated as of September 17, 1999, among
                LEAP WIRELESS INTERNATIONAL, INC., a Delaware corporation (the
                "Parent") and LUCENT TECHNOLOGIES INC., as administrative agent
                (in such capacity, the "Administrative Agent") for the Lenders
                (as defined in the Credit Agreement referred to below).

        Reference is made to the Credit Agreement dated as of September 17, 1999
(as amended, supplemented or otherwise modified from time to time, the "Credit
Agreement"), among Cricket Wireless Communications, Inc. (the "Borrower"),
Cricket Communications, Inc., the lenders from time to time party thereto (the
"Lenders") and the Administrative Agent. Capitalized terms used herein and not
defined herein shall have meanings assigned to such terms in the Credit
Agreement.

        The Lenders have agreed to make Loans to the Borrower pursuant to, and
upon the terms and subject to the conditions specified in, the Credit Agreement.
The Borrower is a subsidiary of the Parent. The obligations of the Lenders to
make Loans are conditioned upon, among other things, the execution and delivery
by the Parent of an agreement in the form hereof to set forth certain covenants,
agreements and obligations of the Parent.

        Accordingly, the Parent and the Administrative Agent, on behalf of
itself and each Lender (and each of their respective successors or assigns),
hereby agree as follows:

        SECTION 1. Guarantee. The Parent unconditionally guarantees, as a
primary obligor and not merely as a surety, the due and punctual payment of the
ChaseTel Loans and any accrued interest thereon (the "ChaseTel Obligations"),
when and as due, whether at maturity, by acceleration, upon one or more dates
set for prepayment or otherwise. The Parent further agrees that the ChaseTel
Obligations may be extended or renewed, in whole or in part, without notice to
or further assent from it, and that it will remain bound upon its guarantee
notwithstanding any extension or renewal of any ChaseTel Obligation.

        SECTION 2. Obligations Not Waived. To the fullest extent permitted by
applicable law, the Parent waives presentment to, demand of payment from and
protest to the Borrower of any of the ChaseTel Obligations, and also waives
notice of acceptance of its guarantee and notice of protest for nonpayment.


<PAGE>   2
                                       2


        SECTION 3. No Discharge or Diminishment of Guarantee. The obligations of
the Parent hereunder shall not be subject to any reduction, limitation,
impairment or termination for any reason (other than the indefeasible payment in
full in cash of all the ChaseTel Obligations), including any claim of waiver,
release, surrender, alteration or compromise of any of the ChaseTel Obligations,
and shall not be subject to any defense or setoff, counterclaim, recoupment or
termination whatsoever by reason of the invalidity, illegality or
unenforceability of the ChaseTel Obligations or otherwise.

        SECTION 4. Defenses of Borrower Waived. To the fullest extent permitted
by applicable law, the Parent waives any defense based on or arising out of any
defense of the Borrower or the unenforceability of the ChaseTel Obligations or
any part thereof from any cause, or the cessation from any cause of the
liability of the Borrower, other than the final and indefeasible payment in full
in cash of all the ChaseTel Obligations.

        SECTION 5. Agreement to Pay; Subordination. In furtherance of the
foregoing and not in limitation of any other right that the Administrative Agent
or any other Lender has at law or in equity against the Parent by virtue hereof,
upon the failure of the Borrower or any other Loan Party to pay any ChaseTel
Obligation when and as the same shall become due, whether at maturity, by
acceleration, after notice of prepayment or otherwise, the Parent hereby
promises to and will forthwith pay, or cause to be paid, to the Administrative
Agent in cash the amount of such unpaid ChaseTel Obligations to be applied by
the Administrative Agent as provided in the Credit Agreement. Upon payment by
the Parent of any sums to the Administrative Agent, all rights of the Parent
against the Borrower arising as a result thereof by way of right of subrogation,
contribution, reimbursement, indemnity or otherwise shall in all respects be
subordinate and junior in right of payment to the prior indefeasible payment in
full in cash of all the Obligations as provided in the Subordination Agreement.

        SECTION 6. Termination. The guarantee made hereunder (a) shall terminate
when all the ChaseTel Obligations have been indefeasibly paid in full and (b)
shall continue to be effective or be reinstated, as the case may be, if at any


<PAGE>   3
                                       3


time payment, or any part thereof, of any ChaseTel Obligation is rescinded or
must otherwise be restored by any Lender or the Parent upon the bankruptcy or
reorganization of the Borrower, the Parent or otherwise. Notwithstanding the
foregoing, the guarantee made hereunder shall terminate
upon the consummation of the ChaseTel Acquisition in
accordance with the terms of the Credit Agreement.

        SECTION 7. Purchase Agreement. (a) If the ChaseTel Acquisition has not
been consummated in accordance with the terms of the Credit Agreement prior to
the date that is one year after the Effective Date, then on the date that is one
year after the Effective Date, the Parent shall pay to the Administrative Agent
in cash the aggregate principal amount of all ChaseTel Loans together with
accrued interest thereon, without utilizing any funds of the Borrower or any
Subsidiary Loan Party, which funds shall be applied to prepay such Loans and
accrued interest.

        (b) Upon payment by the Parent of any sums to the Administrative Agent
pursuant to this Section 7, all rights of the Parent against the Borrower
arising as a result thereof by way of right of subrogation, contribution,
reimbursement, indemnity or otherwise shall constitute Primary Subordinated
Obligations and shall in all respects be subordinate and junior in right of
payment to the prior indefeasible payment in full in cash of all the Obligations
as provided in the Subordination Agreement.

        SECTION 8. Covenants. Until the Commitments have expired or terminated
and the principal of and interest on each Loan and all fees payable under the
Credit Agreement shall have been paid in full, the Parent hereby covenants and
agrees with the Administrative Agent that:

                (a) The Parent will not, nor will it permit any of its direct or
        indirect subsidiaries (other than the Borrower and the Subsidiary Loan
        Parties) to, engage to any material extent in the wireless
        telecommunications and data networking business or any business that
        competes with the business conducted by the Borrower and the Subsidiary
        Loan Parties, in each case, in the United States.

                (b) The Parent and its subsidiaries (other than


<PAGE>   4
                                       4


        the Borrower and the Subsidiary Loan Parties) will cause all assets
        owned by the Parent and its subsidiaries that are used predominantly in
        the business of the Borrower and the Subsidiary Loan Parties to be owned
        by the Borrower and the Subsidiary Loan Parties.

        SECTION 9. ChaseTel Covenants. Unless and until the ChaseTel Acquisition
has been consummated in accordance with the terms of the Credit Agreement, at
any time any ChaseTel Obligations remain outstanding, the Parent covenants and
agrees with the Administrative Agent that:

        (a) The Parent will not enter into any amendment or modification of or
accept any waiver of Section 5.3 of the Credit Agreement dated as of September
23, 1998 among the Parent, as borrower, QUALCOMM Incorporated, the other lenders
named therein and ABN AMRO Bank N.V., as administrative agent (the "QUALCOMM
Credit Agreement");

        (b) The Parent shall comply with the covenants set forth in Section 5 of
the QUALCOMM Credit Agreement, as in effect from time to time;

        (c) Upon the payment of all amounts outstanding under the QUALCOMM
Credit Agreement and the termination of all commitments to lend under the
QUALCOMM Credit Agreement, the Parent shall comply with the covenants set forth
in Section 5 of the QUALCOMM Credit Agreement as in effect as of the Effective
Date, without giving effect to any subsequent amendment or waiver thereto; and

        (d) The Parent will not (i) consolidate or merge with or into any other
Person or (ii) sell, lease or otherwise transfer, directly or indirectly, all or
substantially all of its assets to any other Person unless, in either case, such
Person assumes, in writing, the obligations of the Parent under this Agreement.

        SECTION 10. Waivers; Amendment. (a) No failure or delay of the
Administrative Agent in exercising any power or right hereunder shall operate as
a waiver thereof, nor shall


<PAGE>   5
                                       5


any single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Administrative Agent hereunder and of the other Secured
Parties under the other Loan Documents are cumulative and are not exclusive of
any rights or remedies that they would otherwise have. No waiver of any
provisions of this Agreement or consent to any departure by the Parent therefrom
shall in any event be effective unless the same shall be permitted by paragraph
(b) below, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice or demand on
the Parent in any case shall entitle the Parent to any other or further notice
or demand in similar or other circumstances.

        (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to a written agreement entered into between
the Administrative Agent and the Parent, subject to any consent required in
accordance with Section 9.02 of the Credit Agreement.

        SECTION 11. Notices. All communications and notices hereunder shall be
in writing and given as provided in Section 9.01 of the Credit Agreement;
provided that any communication or notice hereunder to the Parent shall be given
to it at [_________], attention of [_________] (Telecopy No. [_________]).

        SECTION 12. Further Assurances. The Parent agrees to do such further
acts and things, and to execute and deliver such additional conveyances,
assignments, agreements and instruments, as the Administrative Agent may at any
time reasonably request in connection with the administration and enforcement of
this Agreement or in order better to assure and confirm unto the Administrative
Agent its rights and remedies hereunder.

        SECTION 13. Binding Effect; Several Agreement; Assignments. Whenever in
this Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party; and all covenants,
promises and agreements by or on behalf of the Parent that are contained in this
Agreement shall bind and


<PAGE>   6
                                       6


inure to the benefit of its successors and assigns. This Agreement shall become
effective as to the Parent when a counterpart hereof executed on behalf of the
Parent shall have been delivered to the Administrative Agent and a counterpart
hereof shall have been executed on behalf of the Administrative Agent, and
thereafter shall be binding upon the Parent and the Administrative Agent and
their respective successors and assigns, and shall inure to the benefit of the
Parent, the Administrative Agent and the other Secured Parties, and their
respective successors and assigns.

        SECTION 14. Survival of Agreement; Severability. (a) All covenants,
agreements, representations and warranties made by the Parent herein and in the
certificates or other instruments prepared or delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the Administrative Agent and the other Secured Parties
and shall survive the making by the Lenders of the Loans, regardless of any
investigation made by the Secured Parties or on their behalf, and shall continue
in full force and effect as long as the principal of or any accrued interest on
any Loan or any other fee or amount payable under this Agreement or any other
Loan Document is outstanding and unpaid.

        (b) In the event any one or more of the provisions contained in this
Agreement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby (it being understood
that the invalidity of a particular provision in a particular jurisdiction shall
not in and of itself affect the validity of such provision in any other
jurisdiction). The parties shall endeavor in good-faith negotiations to replace
the invalid, illegal or unenforceable provisions with valid provisions the
economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

        SECTION 15. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

        SECTION 16. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute a single contract, and shall become effective
as provided in Section 13. Delivery of an executed counterpart of a signature
page to this Agreement by facsimile transmission shall be as effective as
delivery of a manually executed counterpart of this Agreement.

        SECTION 17. Rules of Interpretation. The rules of interpretation
specified in Section 1.03 of the Credit Agreement shall be applicable to this
Agreement. Section headings used herein are for convenience of reference only,
are not part of this Agreement and are not to affect the construction of, or to
be taken into consideration in interpreting this Agreement.

        SECTION 18. Jurisdiction; Consent to Service of Process. (a) The Parent
hereby irrevocably and unconditionally submits, for itself and its property, to
the nonexclusive jurisdiction of the Supreme Court of the State of New York
sitting in New York County and of the United States District Court of the
Southern District of New York, and any appellate court from any thereof, in any
action or proceeding arising out of or relating to any Loan Document, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State or,
to the extent permitted by law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement or any other Loan
Document shall affect any right that the Administrative Agent or any other
Secured Party may otherwise have to bring any action or proceeding relating to
this Agreement or any other Loan Document against the Parent or its properties
in the courts of any jurisdiction.

        (b) The Parent hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection that it may
now or hereafter have to


<PAGE>   8
                                       8


the laying of venue of any suit, action or proceeding arising out of or relating
to this Agreement or the other Loan Documents in any New York State or Federal
court. Each of the parties hereto hereby irrevocably waives, to the fullest
extent permitted by law, the defense of an inconvenient forum to the maintenance
of such action or proceeding in any such court.

        (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 11. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

        SECTION 19. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT
NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

        IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement
as of the day and year first above written.

                                                                       EXHIBIT F

        PARENT PLEDGE AGREEMENT dated as of September 17, 1999, among LEAP
WIRELESS INTERNATIONAL, INC., a Delaware corporation (the "Parent") and STATE
STREET BANK AND TRUST COMPANY, as collateral agent (in such capacity, the
"Collateral Agent") for the Secured Parties.

        Reference is made to the Collateral Agency and Intercreditor Agreement
dated as of September 17, 1999 (as amended, supplemented or otherwise modified
from time to time, the "Collateral Agency and Intercreditor Agreement") among
Cricket Wireless Communications, Inc., a Delaware corporation (the "Borrower"),
the Representatives and Unrepresented Holders referred to therein and the
Collateral Agent. Capitalized terms used herein and not defined herein shall
have the meanings assigned to such terms in the Collateral Agency and
Intercreditor Agreement. The Parent acknowledges receipt of a true and correct
copy of the Collateral Agency and Intercreditor Agreement and agrees to the
terms thereof.

        The Lenders have agreed to make Loans to the Borrower pursuant to, and
upon the terms and subject to the conditions specified in, the Credit Agreement.
The Borrower is a subsidiary of the Parent. The obligations of the Lenders to
make Loans are conditioned upon, among other things, the execution and delivery
by the Parent of a Pledge Agreement in the form hereof. The Borrower may from
time to time incur Permitted Additional Obligations that are required to be
secured pursuant to the terms hereof.

        Accordingly, the Parent and the Collateral Agent, on behalf of itself
and each Secured Party (and each of their respective successors or assigns),
hereby agree as follows:

        SECTION 1. Pledge. As security for the payment and performance, as the
case may be, in full of the Obligations, the Parent hereby transfers, grants,
bargains, sells, conveys, hypothecates, pledges, sets over and delivers unto the
Collateral Agent, its successors and assigns, and hereby grants to the
Collateral Agent, its successors and assigns, for the ratable benefit of the
Secured Parties, a security interest in all of the Parent's right, title and
interest in, to and under (a), the shares of capital stock, membership interests
or other, equity interests of the Borrower or any Subsidiary Loan Party owned by
it and listed on Schedule I hereto and any shares of the Borrower or any
Subsidiary Loan Party obtained in the future by the Parent and the certificates
representing all such shares,


<PAGE>   2
                                       2


membership interests or other equity interests (collectively, the "Pledged
Stock"); provided that the pledged interests shall not include to the extent
that applicable law requires that the Borrower or any Subsidiary Loan Party
issue directors' qualifying shares, such qualifying shares; (b)(i) all debt
securities issued by the Borrower or any Subsidiary Loan Party owned by it, all
of which are listed on Schedule I hereto, (ii) any debt securities in the future
issued to the Parent by the Borrower or any Subsidiary Loan Party and (iii) the
promissory notes and any other instruments evidencing such debt securities (the
"Pledged Debt Securities"); (c) all other property that may be delivered to and
held by the Collateral Agent pursuant to the terms hereof; (d) subject to
Section 5, all payments of principal or interest, dividends, cash, instruments
and other property from time to time received, receivable or otherwise
distributed, in respect of, in exchange for or upon the conversion of the
securities referred to in clauses (a) and (b) above; (e) subject to Section 5,
all rights and privileges of the Parent with respect to the securities and other
property referred to in clauses (a), (b), (c) and (d) above; and (f) all
proceeds of any of the foregoing (the items referred to in clauses (a) through
(f) above being collectively referred to as the "Collateral"). Upon delivery to
the Collateral Agent, (a) any stock certificates, notes or other securities now
or hereafter included in the Collateral (the "Pledged Securities") shall be
accompanied by stock powers duly executed in blank or other instruments of
transfer satisfactory to the Collateral Agent and by such other instruments and
documents as the Collateral Agent may reasonably request in order to give effect
to the pledge granted hereby and (b) all other property comprising part of the
Collateral shall be accompanied by proper instruments of assignment duly
executed by the Parent and such other instruments or documents as the Collateral
Agent may reasonably request in order to give effect to the pledge granted
hereby. Each delivery of Pledged Securities shall be accompanied by a schedule
describing the securities theretofore and then being pledged hereunder, which
schedule shall be attached hereto as Schedule I and made a part hereof. Each
schedule so delivered shall supersede any prior schedules so delivered.

        TO HAVE AND TO HOLD the Collateral, together with all right, title,
interest, powers, privileges and preferences pertaining or incidental thereto,
unto the Collateral Agent,


<PAGE>   3
                                       3


its successors and assigns, for the ratable benefit of the Secured Parties,
forever; subject, however, to the terms, covenants and conditions hereinafter
set forth.

        SECTION 2. Delivery of the Collateral. (a) The Parent agrees promptly to
deliver or cause to be delivered to the Collateral Agent any and all Pledged
Securities and any and all certificates or other instruments or documents
representing the Collateral.

        (b) The Parent will cause any Indebtedness for borrowed money owed to
the Parent by the Borrower or any Subsidiary Loan Party to be evidenced by a
duly executed promissory note, bond, debenture or similar instrument that is
pledged and delivered to the Collateral Agent pursuant to the terms thereof.

        SECTION 3. Representations, Warranties and Covenants. The Parent hereby
represents, warrants and covenants, as to itself and the Collateral pledged by
it hereunder, to and with the Collateral Agent that as of the Effective Date:

        (a) the Pledged Stock represents that percentage as set forth on
Schedule I of the issued and outstanding shares of each class of the capital
stock of the issuer with respect thereto;

        (b) except for the security interest granted hereunder, the Parent (i)
is and will at all times continue to be the direct owner, beneficially and of
record, of the Pledged Securities indicated on Schedule I, (ii) holds the same
free and clear of all Liens, (iii) will make no assignment, pledge,
hypothecation or transfer of, or create or permit to exist any security interest
in or other Lien on, the Collateral, other than pursuant hereto, and (iv)
subject to Section 5, will cause any and all Collateral, whether for value paid
by the Parent or otherwise, to be forthwith deposited with the Collateral Agent
and pledged or assigned hereunder;

        (c) the Parent (i) has the power and authority to pledge the Collateral
in the manner hereby done or contemplated and (ii) will defend its title or
interest thereto or therein against any and all Liens (other than the Lien
created by this Agreement), however arising, of all Persons whomsoever;


<PAGE>   4
                                       4


        (d) except for such consents and approvals as have been obtained and are
in full force and effect, no consent of any other Person (including stockholders
or creditors of the Parent) and no consent or approval of any Governmental
Authority or any securities exchange was or is necessary to the validity of the
pledge effected hereby;

        (e) by virtue of the execution and delivery by the Parent of this
Agreement, when the Pledged Securities, certificates or other documents
representing or evidencing the Collateral are delivered to, and continue to be
in the possession of, the Collateral Agent in accordance with this Agreement,
the Collateral Agent will have a valid and perfected first lien upon and
security interest in such Pledged Securities as security for the payment and
performance of the Obligations;

        (f) the pledge effected hereby is effective to vest in the Collateral
Agent, on behalf of the Secured Parties, the rights of the Collateral Agent in
the Collateral as set forth herein;

        (g) all of the Pledged Stock has been duly authorized and validly issued
and is fully paid and nonassessable;

        (h) all information set forth herein relating to the Pledged Stock is
accurate and complete in all material respects as of the date hereof; and

        (i) the pledge of the Pledged Stock pursuant to this Agreement does not
violate Regulation U or X of the Federal Reserve Board or any successor thereto
as of the date hereof.

        SECTION 4. Registration in Nominee Name; Denominations. The Collateral
Agent, on behalf of the Secured Parties, shall have the right (in its sole and
absolute discretion) to hold the Pledged Securities in its own name as pledgee,
the name of its nominee (as pledgee or as sub-agent) or the name of the Parent,
endorsed or assigned in blank or in favor of the Collateral Agent. The Parent
will promptly give to the Collateral Agent copies of any material notices or
other communications received by it with respect to Pledged Securities
registered in the name of the Parent. The Collateral Agent shall at all times
have the right to exchange the certificates representing Pledged


<PAGE>   5
                                       5


Securities for certificates of smaller or larger denominations for any purpose
consistent with this Agreement.

        SECTION 5. Voting Rights; Dividends and Interest, etc. (a) Unless and
until a Notice of Enforcement is in effect:

                (i) The Parent shall be entitled to exercise any and all voting
        and/or other consensual rights and powers inuring to an owner of Pledged
        Securities or any part thereof for any purpose consistent with the terms
        of this Agreement, the other Support Documents and the Secured
        Instruments; provided, however, that the Parent will not be entitled to
        exercise any such right if the result thereof could materially and
        adversely affect the rights inuring to a holder of the Pledged
        Securities or the rights and remedies of any of the Secured Parties
        under this Agreement or any other Support Document or Secured Instrument
        or the ability of the Secured Parties to exercise the same.

                (ii) The Collateral Agent shall execute and deliver to the
        Parent, or cause to be executed and delivered to the Parent, all such
        proxies, powers of attorney and other instruments as the Parent may
        reasonably request for the purpose of enabling the Parent to exercise
        the voting and/or consensual rights and powers it is entitled to
        exercise pursuant to subparagraph (i) above and to receive the cash
        dividends it is entitled to receive pursuant to subparagraph (iii)
        below.

                (iii) The Parent shall be entitled to receive and retain any and
        all cash dividends, interest and principal paid on the Pledged
        Securities to the extent and only to the extent that such cash
        dividends, interest and principal are permitted by, and otherwise paid
        in accordance with, the terms and conditions of the Support Documents,
        the Secured Instruments and applicable laws. While a Notice of
        Enforcement is in effect, all noncash dividends, interest and principal,
        and all dividends, interest and principal paid or payable in cash or
        otherwise in connection with a partial or total liquidation or
        dissolution, return of capital, capital surplus or paid-in surplus, and
        all


<PAGE>   6
                                       6


        other distributions (other than distributions referred to in the
        preceding sentence) made on or in respect of the Pledged Securities,
        whether paid or payable in cash or otherwise, whether resulting from a
        subdivision, combination or reclassification of the outstanding capital
        stock of the issuer of any Pledged Securities or received in exchange
        for Pledged Securities or any part thereof, or in redemption thereof, or
        as a result of any merger, consolidation, acquisition or other exchange
        of assets to which such issuer may be a party or otherwise, shall be and
        become part of the Collateral, and, if received by the Parent, shall not
        be commingled by the Parent with any of its other funds or property but
        shall be held separate and apart therefrom, shall be held in trust for
        the benefit of the Collateral Agent and shall be forthwith delivered to
        the Collateral Agent in the same form as so received (with any necessary
        endorsement).

        (b) While a Notice of Enforcement is in effect, all rights of the Parent
to dividends, interest or principal that the Parent is authorized to receive
pursuant to paragraph (a)(iii) above shall cease, and all such rights shall
thereupon become vested in the Collateral Agent, which shall have the sole and
exclusive right and authority to receive and retain such dividends, interest or
principal. All dividends, interest or principal received by the Parent contrary
to the provisions of this Section 5 shall be held in trust for the benefit of
the Collateral Agent, shall be segregated from other property or funds of the
Parent and shall be forthwith delivered to the Collateral Agent upon demand in
the same form as so received (with any necessary endorsement). Any and all money
and other property paid over to or received by the Collateral Agent pursuant to
the provisions of this paragraph (b) shall be retained by the Collateral Agent
in the Enforcement Collateral Account upon receipt of such money or other
property and shall be applied in accordance with the provisions of Section 7.
After a Notice of Enforcement has been rescinded in accordance with the terms of
the Collateral Agency and Intercreditor Agreement, the Collateral Agent shall,
within five Business Days after all such Notices of Enforcement have been
rescinded, repay to the Parent all cash dividends, interest or principal
(without interest), that the Parent would otherwise be permitted to retain
pursuant to the terms of paragraph (a)(iii) above and which remain in the
Enforcement Collateral Account.


<PAGE>   7
                                       7


        (c) While a Notice of Enforcement is in effect, all rights of the Parent
to exercise the voting and consensual rights and powers it is entitled to
exercise pursuant to paragraph (a)(i) of this Section 5, and the obligations of
the Collateral Agent under paragraph (a)(ii) of this Section 5, shall cease, and
all such rights shall thereupon become vested in the Collateral Agent, which
shall have the sole and exclusive right and authority to exercise such voting
and consensual rights and powers in a manner not inconsistent with the terms of
this Agreement, provided that, unless otherwise directed by the Required Secured
Parties, the Collateral Agent shall have the right from time to time while a
Notice of Enforcement is in effect to permit the Parent to exercise such rights.
After all Notices of Enforcement have been rescinded in accordance with the
terms of the Collateral Agency and Intercreditor Agreement, the Parent will have
the right to exercise the voting and consensual rights and powers that it would
otherwise be entitled to exercise pursuant to the terms of paragraph (a)(i)
above.

        SECTION 6. Remedies upon Default. While a Notice of Enforcement is in
effect, subject to applicable regulatory and legal requirements, the Collateral
Agent may sell the Collateral, or any part thereof, at public or private sale or
at any broker's board or on any securities exchange, for cash, upon credit or
for future delivery as the Collateral Agent shall deem appropriate subject to
applicable law and standards of commercial reasonableness. The Collateral Agent
shall be authorized at any such sale (if it deems it advisable to do so) to
restrict the prospective bidders or purchasers to Persons who will represent and
agree that they are purchasing the Collateral for their own account for
investment and not with a view to the distribution or sale thereof, and upon
consummation of any such sale the Collateral Agent shall have the right to
assign, transfer and deliver to the purchaser or purchasers thereof the
Collateral so sold. Each such purchaser at any such sale shall hold the property
sold absolutely free from any claim or right on the part of the Parent, and, to
the extent permitted by applicable law, the Parent hereby waives all rights of
redemption, stay, valuation and appraisal the Parent now has or may at any time
in the future have under any rule of law or statute now existing or hereafter
enacted.

        The Collateral Agent shall give the Parent 10 days' prior written notice
(which the Parent agrees is reasonable notice within the meaning of Section
9-504(3) of the Uniform Commercial Code as in effect in the State of New York or
its equivalent in other jurisdictions) of the Collateral Agent's intention to
make any sale of the Parent's Collateral. Such notice, in the case of a public
sale, shall state the time and place for such sale and, in the case of a sale at
a broker's board or on a securities exchange, shall state the board or exchange
at which such sale is to be made and the day on which the Collateral, or portion
thereof, will first be offered for sale at such board or exchange. Any such
public sale shall be held at such time or times within ordinary business hours
and at such place or places as the Collateral Agent may fix and state in the
notice of such sale. At any such sale, the Collateral, or portion thereof, to be
sold may be sold in one lot as an entirety or in separate parcels, as the
Collateral Agent may (in its sole and absolute discretion) determine. The
Collateral Agent shall not be obligated to make any sale of any Collateral if it
shall determine not to do so, regardless of the fact that notice of sale of such
Collateral shall have been given. The Collateral Agent may, without notice or
publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for
sale, and such sale may, without further notice, be made at the time and place
to which the same was so adjourned. In case any sale of all or any part of the
Collateral is made on credit or for future delivery, the Collateral so sold may
be retained by the Collateral Agent until the sale price is paid in full by the
purchaser or purchasers thereof, but the Collateral Agent shall not incur any
liability in case any such purchaser or purchasers shall fail to take up and pay
for the Collateral so sold and, in case of any such failure, such Collateral may
be sold again upon like notice. Subject to Section 9.05 of the Collateral Agency
and Intercreditor Agreement, at any public (or, to the extent permitted by
applicable law, private) sale made pursuant to this Section 6, any Secured Party
may bid for or purchase, free from any right of redemption, stay or appraisal on
the part of the Parent (all said rights being also hereby waived and released),
the Collateral or any part thereof offered for sale. For purposes hereof, (a) a
written agreement to purchase the Collateral or any portion thereof shall be
treated as a sale thereof, (b) the Collateral Agent shall be free to carry out
such sale


<PAGE>   9
                                       9


pursuant to such agreement and (c) the Parent shall not be entitled to the
return of the Collateral or any portion thereof subject thereto, notwithstanding
the fact that after the Collateral Agent shall have entered into such an
agreement the applicable Notice of Enforcement shall have been rescinded in
accordance with the terms of the Collateral Agency and Intercreditor Agreement
and the Obligations paid in full. As an alternative to exercising the power of
sale herein conferred upon it, the Collateral Agent may proceed by a suit or
suits at law or in equity to foreclose upon the Collateral and to sell the
Collateral or any portion thereof pursuant to a judgment or decree of a court or
courts having competent jurisdiction or pursuant to a proceeding by a
court-appointed receiver. Any sale pursuant to the provisions of this Section 6
shall be deemed to conform to the commercially reasonable standards as provided
in Section 9-504(3) of the Uniform Commercial Code as in effect in the State of
New York or its equivalent in other jurisdictions.

        SECTION 7. Application of Proceeds of Sale. The proceeds of any sale of
Collateral pursuant to Section 6, as well as any Collateral consisting of cash,
shall be applied promptly by the Collateral Agent after receipt thereof as
provided in the Collateral Agency and Intercreditor Agreement.

        Upon any sale of the Collateral by the Collateral Agent (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the purchase money by the Collateral Agent or of the officer
making the sale shall be a sufficient discharge to the purchaser or purchasers
of the Collateral so sold and such purchaser or purchasers shall not be
obligated to see to the application of any part of the purchase money paid over
to the Collateral Agent or such officer or be answerable in any way for the
misapplication thereof.

        SECTION 8. Reimbursement of Collateral Agent. (a) The Parent agrees to
pay upon demand to the Collateral Agent the amount of any and all reasonable
expenses, including the reasonable fees, other charges and disbursements of its
counsel and of any experts or agents, that the Collateral Agent may incur in
connection with (i) the administration of this Agreement, (ii) the custody or
preservation of, or the sale of, collection from, or other realization upon, any
of the Collateral, (iii) the exercise or enforcement of any of the rights of the



<PAGE>   10
                                       10


Collateral Agent hereunder or (iv) the failure by the Parent to perform or
observe any of the provisions hereof.

        (b) Without limitation of its indemnification obligations under the
other Support Documents, the Parent agrees to indemnify the Collateral Agent and
the other Indemnitees against, and hold each Indemnitee harmless from, any and
all losses, claims, damages, liabilities and related expenses, including
reasonable counsel fees, other charges and disbursements, incurred by or
asserted against any Indemnitee arising out of, in any way connected with, or as
a result of (i) the execution or delivery of this Agreement or any other Support
Document or any agreement or instrument contemplated hereby or thereby, the
performance by the parties hereto of their respective obligations thereunder or
the consummation of the transactions contemplated hereby or (ii) any claim,
litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto, provided that such indemnity
shall not, as to any Indemnitee, be available to the extent that such losses,
claims, damages, liabilities or related expenses have resulted from the gross
negligence or wilful misconduct of such Indemnitee.

        (c) Any amounts payable as provided hereunder shall be additional
Obligations secured hereby and by the other Security Documents. The provisions
of this Section 8 shall remain operative and in full force and effect regardless
of the termination of this Agreement or any other Support Document or any
Secured Instrument, the consummation of the transactions contemplated hereby,
the repayment of any of the Obligations, the invalidity or unenforceability of
any term or provision of this Agreement or any other Support Document or any
Secured Instrument or any investigation made by or on behalf of the Collateral
Agent or any other Secured Party. All amounts due under this Section 8 shall be
payable on written demand therefor and, if not paid within five Business Days
after written demand for payment is received by the Parent from the Collateral
Agent, shall bear interest at the rate specified in Section 2.11(c) of the
Credit Agreement.

        (d) To the extent that the Parent fails to pay any amount required to be
paid by them to the Collateral Agent under paragraph (a) or (b) of this Section,
each Secured Party severally agrees to pay to the Collateral Agent such Secured
Party's pro rata share (determined as of the time


<PAGE>   11
                                       11


that the applicable unreimbursed expense or indemnity payment is sought) of such
unpaid amount; provided that the unreimbursed expense or indemnified loss,
claim, damaged, liability or related expense, as the case may be, was incurred
by or asserted against the Collateral Agent in its capacity as such. For
purposes hereof, a Secured Party's "pro rata share" shall be determined based
upon its share of the sum of the total outstanding loans and unused commitments
under the Secured Instruments at the time.

        SECTION 9. Collateral Agent Appointed Attorney-in-Fact. The Parent
hereby appoints the Collateral Agent, effective while a Notice of Enforcement is
in effect, the attorney-in-fact of the Parent for the purpose of carrying out
the provisions of this Agreement and taking any action and executing any
instrument that the Collateral Agent may deem necessary or advisable to
accomplish the purposes hereof, which appointment is irrevocable and coupled
with an interest. Without limiting the generality of the foregoing, the
Collateral Agent shall have the right, while a Notice of Enforcement is in
effect, with full power of substitution either in the Collateral Agent's name or
in the name of the Parent, to ask for, demand, sue for, collect, receive and
give acquittance for any and all moneys due or to become due under and by virtue
of any Collateral, to endorse checks, drafts, orders and other instruments for
the payment of money payable to the Parent representing any interest or dividend
or other distribution payable in respect of the Collateral or any part thereof
or on account thereof and to give full discharge for the same, to settle,
compromise, prosecute or defend any action, claim or proceeding with respect
thereto, and to sell, assign, endorse, pledge, transfer and to make any
agreement respecting, or otherwise deal with, the same, in each case in a manner
not inconsistent with the terms of this Agreement; provided, however, that
nothing herein contained shall be construed as requiring or obligating the
Collateral Agent to make any commitment or to make any inquiry as to the nature
or sufficiency of any payment received by the Collateral Agent, or to present or
file any claim or notice, or to take any action with respect to the Collateral
or any part thereof or the moneys due or to become due in respect thereof or any
property covered thereby. The Collateral Agent and the other Secured Parties
shall be accountable only for amounts actually received as a result of the
exercise of the powers granted to them herein, and neither they nor their
officers,


<PAGE>   12
                                       12


directors, employees or agents shall be responsible to the Parent for any act or
failure to act hereunder, except for their own gross negligence or wilful
misconduct.

        SECTION 10. Waivers; Amendment. (a) No failure or delay of the
Collateral Agent in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Collateral Agent hereunder
and of the Collateral Agent and the other Secured Parties under the other
Support Documents and the Secured Instruments are cumulative and are not
exclusive of any rights or remedies that they would otherwise have. No waiver of
any provisions of this Agreement or consent to any departure by the Parent
therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) below, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. No notice or demand
on the Parent in any case shall entitle the Parent to any other or further
notice or demand in similar or other circumstances.

        (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to a written agreement entered into between
the Collateral Agent and the Parent, subject to any consent required in
accordance with Section 11.02 of the Collateral Agency and Intercreditor
Agreement.

        SECTION 11. Securities Act, etc. In view of the position of the Parent
in relation to the Pledged Securities, or because of other current or future
circumstances, a question may arise under the Securities Act of 1933, as now or
hereafter in effect, or any similar statute hereafter enacted analogous in
purpose or effect (such Act and any such similar statute as from time to time in
effect being called the "Federal Securities Laws") with respect to any
disposition of the Pledged Securities permitted hereunder. The Parent
understands that compliance with the Federal Securities Laws might very strictly
limit the course of conduct of the Collateral Agent if the Collateral Agent were
to attempt to dispose of all or any part of the Pledged Securities, and might
also limit the extent to which or the manner in which any subsequent


<PAGE>   13
                                       13


transferee of any Pledged Securities could dispose of the same. Similarly, there
may be other legal restrictions or limitations affecting the Collateral Agent in
any attempt to dispose of all or part of the Pledged Securities under applicable
Blue Sky or other state securities laws or similar laws analogous in purpose or
effect. The Parent recognizes that in light of such restrictions and limitations
the Collateral Agent may, with respect to any sale of the Pledged Securities,
limit the purchasers to those who will agree, among other things, to acquire
such Pledged Securities for their own account, for investment, and not with a
view to the distribution or resale thereof. The Parent acknowledges and agrees
that in light of such restrictions and limitations, the Collateral Agent, in its
sole and absolute discretion, (a) may proceed to make such a sale whether or not
a registration statement for the purpose of registering such Pledged Securities
or part thereof shall have been filed under the Federal Securities Laws and (b)
may approach and negotiate with a single potential purchaser to effect such
sale. The Parent acknowledges and agrees that any such sale might result in
prices and other terms less favorable to the seller than if such sale were a
public sale without such restrictions. In the event of any such sale, the
Collateral Agent shall incur no responsibility or liability for selling all or
any part of the Pledged Securities at a price that the Collateral Agent, in its
sole and absolute discretion, may in good faith deem reasonable under the
circumstances, notwithstanding the possibility that a substantially higher price
might have been realized if the sale were deferred until after registration as
aforesaid or if more than a single purchaser were approached. The provisions of
this Section 11 will apply notwithstanding the existence of a public or private
market upon which the quotations or sales prices may exceed substantially the
price at which the Collateral Agent sells.

        SECTION 12. Security Interest Absolute. All rights of the Collateral
Agent hereunder, the grant of a security interest in the Collateral and all
obligations of the Parent hereunder, shall be absolute and unconditional
irrespective of (a) any lack of validity or enforceability any Support Document
or Secured Instrument, any agreement with respect to any of the Obligations or
any other agreement or instrument relating to any of the foregoing, (b) any
change in the time, manner or place of payment of, or in any other term of, all
or any of the Obligations, or any other


<PAGE>   14
                                       14


amendment or waiver of or any consent to any departure from any Support Document
or Secured Instrument or any other agreement or instrument relating to any of
the foregoing, (c) any exchange, release or nonperfection of any other
collateral, or any release or amendment or waiver of or consent to or departure
from any guaranty, for all or any of the Obligations or (d) any other
circumstance that might otherwise constitute a defense available to, or a
discharge of, the Parent in respect of the Obligations or in respect of this
Agreement (other than the indefeasible payment in full of all the Obligations).

        SECTION 13. Termination or Release. (a) This Agreement and the security
interests granted hereby shall terminate when all the Obligations have been
indefeasibly paid in full and all Secured Instrument Commitments shall have
terminated.

        (b) Subject to Section 9.03 of the Collateral Agency and Intercreditor
Agreement, upon any sale or other transfer by the Parent of any Collateral that
does not violate any Secured Instrument to any Person other than Holdings, the
Borrower or any Subsidiary Loan Party, the security interest in such Collateral
shall be automatically released.

        (c) In connection with any termination or release pursuant to paragraph
(a) or (b), the Collateral Agent shall execute and deliver to the Parent, at the
Parent's expense, all documents that the Parent shall reasonably request to
evidence such termination or release. Any execution and delivery of documents
pursuant to this Section 13 shall be without recourse to or warranty by the
Collateral Agent.

        SECTION 14. Notices. All communications and notices hereunder shall be
in writing and given as provided in Section 11.01 of the Collateral Agency and
Intercreditor Agreement; provided that any communication or notice hereunder to
the Parent shall be given to it at [__________], attention of [__________]
(Telecopy No. [__________]).

        SECTION 15. Further Assurances. The Parent agrees to do such further
acts and things, and to execute and deliver such additional conveyances,
assignments, agreements and instruments, as the Collateral Agent may at any time
reasonably request in connection with the administration and enforcement of this
Agreement or with respect to the Collateral or any part thereof or in order
better to assure


<PAGE>   15
                                       15


and confirm unto the Collateral Agent its rights and remedies hereunder.

        SECTION 16. Binding Effect; Several Agreement; Assignments. Whenever in
this Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party; and all covenants,
promises and agreements by or on behalf of the Parent that are contained in this
Agreement shall bind and inure to the benefit of its successors and assigns.
This Agreement shall become effective as to the Parent when a counterpart hereof
executed on behalf of the Parent shall have been delivered to the Collateral
Agent and a counterpart hereof shall have been executed on behalf of the
Collateral Agent, and thereafter shall be binding upon the Parent and the
Collateral Agent and their respective successors and assigns, and shall inure to
the benefit of the Parent, the Collateral Agent and the other Secured Parties,
and their respective successors and assigns, except that the Parent shall not
have the right to assign its rights hereunder or any interest herein or in the
Collateral (and any such attempted assignment shall be void), except as
expressly contemplated by this Agreement or the other Loan Documents. Subject to
Section 9.03 of the Collateral Agency and Intercreditor Agreement, if all of the
capital stock of the Borrower or a Subsidiary Loan Party is sold, transferred or
otherwise disposed of to a Person other than the Borrower or a Subsidiary Loan
Party pursuant to a transaction that does not violate any Secured Instrument,
such capital stock shall be released from any security interest, lien or
encumbrance created under this Agreement without further action.

        SECTION 17. Survival of Agreement; Severability. (a) All covenants,
agreements, representations and warranties made by the Parent herein and in the
certificates or other instruments prepared or delivered in connection with or
pursuant to this Agreement or any other Support Document shall be considered to
have been relied upon by the Collateral Agent and the other Secured Parties and
shall survive the extension of credit by any Secured Party pursuant to a Secured
Instrument, regardless of any investigation made by the Secured Parties or on
their behalf, and shall continue in full force and effect until this Agreement
shall terminate.

        (b) In the event any one or more of the provisions


<PAGE>   16
                                       16


contained in this Agreement should be held invalid, illegal or unenforceable in
any respect, the validity, legality and enforceability of the remaining
provisions contained herein shall not in any way be affected or impaired thereby
(it being understood that the invalidity of a particular provision in a
particular jurisdiction shall not in and of itself affect the validity of such
provision in any other jurisdiction). The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

        SECTION 18. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

        SECTION 19. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute a single contract, and shall become effective
as provided in Section 16. Delivery of an executed counterpart of a signature
page to this Agreement by facsimile transmission shall be as effective as
delivery of a manually executed counterpart of this Agreement.

        SECTION 20. Rules of Interpretation. The rules of interpretation
specified in Section 1.02 of the Collateral Agency and Intercreditor Agreement
shall be applicable to this Agreement. Section headings used herein are for
convenience of reference only, are not part of this Agreement and are not to
affect the construction of, or to be taken into consideration in interpreting
this Agreement.

        SECTION 21. Jurisdiction; Consent to Service of Process. (a) The Parent
hereby irrevocably and unconditionally submits, for itself and its property, to
the nonexclusive jurisdiction of the Supreme Court of the State of New York
sitting in New York County and of the United States District Court of the
Southern District of New York, and any appellate court from any thereof, in any
action or proceeding arising out of or relating to any this Agreement or any
other Support Document, or for recognition or enforcement of any judgment, and
each of the parties hereto hereby irrevocably and unconditionally agrees that
all claims in respect of any such action or proceeding may be


<PAGE>   17
                                       17


heard and determined in such New York State or, to the extent permitted by law,
in such Federal court. Each of the parties hereto agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law. Nothing in this Agreement or any other Support Document shall affect any
right that the Collateral Agent or any other Secured Party may otherwise have to
bring any action or proceeding relating to this Agreement or any other Loan
Document against the Parent or its properties in the courts of any jurisdiction.

        (b) The Parent hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection that it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or any other Support Document in
any New York State or Federal court. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

        (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 14. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

        SECTION 22. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT
NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

        SECTION 23. Execution of Financing Statements. Pursuant to Section 9-402
of the Uniform Commercial Code as in effect in the State of New York, the Parent
authorizes the Collateral Agent to file financing statements with


<PAGE>   18
                                       18


respect to the Collateral owned by it without the signature of the Parent in
such form and in such filing offices as the Collateral Agent reasonably
determines appropriate to perfect the security interests of the Collateral Agent
under this Agreement. A carbon, photographic or other reproduction of this
Agreement shall be sufficient as a financing statement for filing in any
jurisdiction.

        IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement
as of the day and year first above written.

                                Security Interest

        SECTION 2.01. Security Interest. As security for the payment or
performance, as the case may be, in full of the Obligations, each Grantor hereby
bargains, sells, conveys, assigns, sets over, mortgages, pledges, hypothecates
and transfers to the Collateral Agent, its successors and assigns, for the
ratable benefit of the Secured Parties, and hereby grants to the Collateral
Agent, its successors and assigns, for the ratable benefit of the Secured
Parties, a security interest in, all of such Grantor's right, title and interest
in, to and under the Collateral (the "Security Interest"). Without limiting the
foregoing, the Collateral Agent is hereby authorized to file one or more
financing statements (including fixture filings), continuation statements,
filings with the United States Patent and Trademark Office or United States
Copyright Office (or any successor office or any similar office in any other
country) or other documents for the purpose of perfecting, confirming,
continuing, enforcing or protecting the Security Interest granted by each
Grantor, without the signature of any Grantor, and naming any Grantor or the
Grantors as debtors and the Collateral Agent as secured party.

        SECTION 2.02. No Assumption of Liability. The Security Interest is
granted as security only and shall not subject the Collateral Agent or any other
Secured Party to, or in any way alter or modify, any obligation or liability of
any Grantor with respect to or arising out of the Collateral.

                                   ARTICLE III

                         Representations and Warranties

        The Grantors jointly and severally represent and warrant to the
Collateral Agent and the Secured Parties that:

        SECTION 3.01. Title and Authority. Each Grantor has good title to, or
valid leasehold interest in, the


<PAGE>   10
                                       10


Collateral material to its business with respect to which it has purported to
grant a Security Interest hereunder, except for minor defects in title that do
not interfere with its ability to conduct its business as currently conducted or
to utilize such properties for their intended purposes and subject to Liens
permitted by the Credit Agreement and has full power and authority to grant to
the Collateral Agent the Security Interest in such Collateral pursuant hereto
and to execute, deliver and perform its obligations in accordance with the terms
of this Agreement, without the consent or approval of any other Person other
than any consent or approval which has been obtained.

        SECTION 3.02. Filings. (a) The Perfection Certificate has been duly
prepared, completed and executed and the information set forth therein is
correct and complete in all material respects. Each Grantor has or will deliver
to the Collateral Agent fully executed Uniform Commercial Code financing
statements (including fixture filings, as applicable) or other appropriate
filings, recordings or registrations containing a description of the Collateral
for filing in each governmental, municipal or other office in the United States
requested by the Collateral Agent and specified in Schedule 6 to the Perfection
Certificate, which are all the filings, recordings and registrations (other than
filings required to be made in the United States Patent and Trademark Office and
the United States Copyright Office in order to perfect the Security Interest in
Collateral consisting of United States Patents, Trademarks and Copyrights) that
are necessary in the United States to publish notice of and protect the validity
of and to establish a legal, valid and perfected security interest in favor of
the Collateral Agent (for the ratable benefit of the Secured Parties) in respect
of all Collateral in which the Security Interest may be perfected by filing,
recording or registration in the United States (or any political subdivision
thereof) and its territories and possessions, and no further or subsequent
filing, refiling, recording, rerecording, registration or reregistration is
necessary in any such jurisdiction, except as provided under applicable law with
respect to the filing of continuation statements.

        (b) Each Grantor represents and warrants that fully executed security
agreements in the form hereof and


<PAGE>   11
                                       11


containing a description of all Collateral consisting of Intellectual Property
shall have been received and recorded within three months after the execution of
this Agreement with respect to United States Patents and United States
registered Trademarks (and Trademarks for which United States registration
applications are pending) and within one month after the execution of this
Agreement with respect to United States registered Copyrights by the United
States Patent and Trademark Office and the United States Copyright Office
pursuant to 35 U.S.C. Section 261, 15 U.S.C. Section 1060 or 17 U.S.C. Section
205 and the regulations thereunder, as applicable, and otherwise as may be
required pursuant to the laws of any other necessary jurisdiction, to protect
the validity of and to establish a legal, valid and perfected security interest
in favor of the Collateral Agent (for the ratable benefit of the Secured
Parties) in respect of all Collateral consisting of Patents, Trademarks and
Copyrights in which a security interest may be perfected by filing, recording or
registration in the United States (or any political subdivision thereof) and
its territories and possessions, or in any other necessary jurisdiction, and no
further or subsequent filing, refiling, recording, rerecording, registration or
reregistration is necessary (other than such actions as are necessary to perfect
the Security Interest with respect to any Collateral consisting of Patents,
Trademarks and Copy rights (or registration or application for registration
thereof) acquired or developed after the date hereof).

        SECTION 3.03. Validity of Security Interest. The Security Interest
constitutes (a) a legal and valid security interest in all the Collateral
securing the payment and performance of the Obligations, (b) subject to the
filings described in Section 3.02 above, a perfected security interest in all
Collateral in which a security interest may be perfected by filing, recording or
registering a financing statement or analogous document in the United States (or
any political subdivision thereof) and its territories and possessions pursuant
to the Uniform Commercial Code or other applicable law in such jurisdictions and
(c) a security interest that shall be perfected in all Collateral in which a
security interest may be perfected upon the receipt and


<PAGE>   12
                                       12


recording of this Agreement with the United States Patent and Trademark Office
and the United States Copyright Office, as applicable, within the three-month
period (commencing as of the date hereof) pursuant to 35 U.S.C. 261 or 15 U.S.C.
Section 1060 or the one-month period (commencing as of the date hereof) pursuant
to 17 U.S.C. Section 205 and otherwise as may be required pursuant to the laws
of any other necessary jurisdiction. The Security Interest is and shall be prior
to any other Lien on any of the Collateral, other than Liens expressly permitted
to be prior to the Security Interest under each Secured Instrument.

        SECTION 3.04. Absence of Other Liens. The Collateral is owned by the
Grantors free and clear of any Lien, except for Liens expressly permitted under
each Secured Instrument and except for restrictions on transfer, assignment, use
and rights of first refusal and similar rights under the terms of any leases,
licenses and other agreements under which the Grantors acquired rights in and to
Collateral. No Grantor has filed or consented to the filing of (a) any financing
statement or analogous document under the Uniform Commercial Code or any other
applicable laws covering any Collateral, (b) any assignment in which any Grantor
assigns any Collateral or any security agreement or similar instrument covering
any Collateral with the United States Patent and Trademark Office or the United
States Copyright Office or (c) any assignment in which any Grantor assigns any
Collateral or any security agreement or similar instrument covering any
Collateral with any foreign governmental, municipal or other office, which
financing statement or analogous document, assignment, security agreement or
similar instrument is still in effect, except, in each case, for Liens expressly
permitted under each Secured Instrument and except for financing statements
evidencing Liens being terminated on the Effective Date.

                                   ARTICLE IV

                                    Covenants

        SECTION 4.01. Change of Name; Location of Collateral; Records; Place of
Business. (a) Each Grantor agrees to promptly notify in writing the Collateral
Agent, but in no event later than 30 days after such change, of any change


<PAGE>   13
                                       13


(i) in its corporate name or in any trade name used to identify it in the
conduct of its business or in the owner ship of its properties, (ii) in the
location of its chief executive office, its principal place of business, any
office in which it maintains books or records relating to Collateral owned by it
or any office or facility at which Collateral owned by it is located (including
the establishment of any such new office or facility), (iii) in its corporate
structure or (iv) in its Federal Taxpayer Identification Number. Each Grantor
agrees to make within 45 days, after the occurrence of any of the foregoing
changes, all filings under the Uniform Commercial Code or otherwise that are
required by the Collateral Agent in order for the Collateral Agent to continue
at all times following such change to have a valid, legal and perfected first
priority security interest in all the Collateral.

        (b) Each Grantor agrees to maintain, at its own cost and expense, such
complete and accurate records with respect to the Collateral owned by it as is
consistent with its current practices and in accordance with such prudent and
standard practices used in industries that are the same as or similar to those
in which such Grantor is engaged, but in any event to include complete
accounting records indicating all payments and proceeds received with respect to
any part of the Collateral.

        SECTION 4.02. Periodic Certification. Within 90 days after the end of
each fiscal year of the Borrower, the Borrower shall deliver to the Collateral
Agent a certificate executed by an executive officer or a Financial Officer of
the Borrower (a) setting forth the information required pursuant to Section 2 of
the Perfection Certificate or confirming that there has been no change in such
information since the date of such certificate or the date of the most recent
certificate delivered pursuant to this Section 4.02 and (b) certifying that all
Uniform Commercial Code financing statements (including fixture filings, as
applicable) or other appropriate filings, recordings or registra tions,
including all refilings, rerecordings and reregistrations, containing a
description of the Collateral have been filed of record in each governmental,
municipal or


<PAGE>   14
                                       13


other appropriate office in each jurisdiction identified pursuant to clause (a)
above to the extent necessary to protect and perfect the Security Interest or
identifying such additional Uniform Commercial Code financing statements or
other appropriate filings, recordings or registrations as may be required to
protect and perfect the security interests hereunder which, upon the request of
the Collateral Agent, shall be filed, recorded or registered, in either case for
a period of not less than 18 months after the date of such certificate (except
as noted therein with respect to any continuation statements to be filed within
such period). Each certificate delivered pursuant to this Section 4.02 shall
identify in the format of Schedule II, III, IV or V, as applicable, all
Intellectual Property of any Grantor in existence on the date thereof and not
then listed on such Schedules or previously so identified to the Collateral
Agent.

        SECTION 4.03. Protection of Security. Each Grantor shall, at its own
cost and expense, take any and all reasonable actions necessary to defend title
to the Collateral against all Persons and to defend the Security Interest of the
Collateral Agent in the Collateral and the priority thereof against any Lien not
expressly permitted under each Secured Instrument.

        SECTION 4.04. Further Assurances. Each Grantor agrees, at its own
expense, (x) to execute, acknowledge, deliver and cause to be duly filed all
such further instruments and documents and take all such actions as the
Collateral Agent may from time to time reasonably request to better assure,
preserve, protect and perfect the Security Interest and the rights and remedies
created hereby, including the payment of any fees and taxes required in
connection with the execution and delivery of this Agreement, the granting of
the Security Interest and the filing of any financing statements (including
fixture filings) or other documents in connection herewith or therewith and (y)
at the request of the Collateral Agent, to enter into and to cause any
Securities Intermediary through which it holds Investment Property to enter into
(or to reinvest through a Securities Intermediary who will enter into) a control
agreement, in form and substance satisfactory to the Collateral Agent, pursuant
to which such Securities Intermediary grants "control", within the meaning


<PAGE>   15
                                       15


of Section 8-106 of the Uniform Commercial Code of the State of New York, over
such Investment Property to the Collateral Agent. If any amount payable under or
in connection with any of the Collateral shall be or become evidenced by any
promissory note or other instrument, such note or instrument shall be forthwith
pledged and delivered to the Collateral Agent, duly endorsed in a manner
satisfactory to the Collateral Agent.

        Without limiting the generality of the foregoing, each Grantor hereby
authorizes the Collateral Agent, with prompt notice thereof to the Grantors, to
supplement this Agreement by supplementing Schedule II, III, IV or V hereto or
adding additional schedules hereto to specifically identify any asset or item
that may constitute Copyrights, Licenses, Patents or Trademarks; provided,
however, that any Grantor shall have the right, exercisable within 45 days after
it has been notified by the Collateral Agent of the specific identification of
such Collateral, to advise the Collateral Agent in writing of any inaccuracy of
the representations and warranties made by such Grantor hereunder with respect
to such Collateral. Each Grantor agrees that it will use its reasonable best
efforts to take such action as shall be necessary in order that all
representations and warranties hereunder shall be true and correct with respect
to such Collateral within 30 days after the date it has been notified by the
Collateral Agent of the specific identification of such Collateral.

        SECTION 4.05. Inspection and Verification. The Collateral Agent and such
Persons as the Collateral Agent may reasonably designate shall have the right,
at the Grantors' own cost and expense, to inspect the Collateral, all records
related thereto (and to make extracts and copies from such records) and the
premises upon which any of the Collateral is located, to discuss the Grantors'
affairs with the officers of the Grantors and their independent accountants and
to verify under reasonable procedures the validity, amount, quality, quantity,
value, condition and status of, or any other matter relating to, the Collateral,
including, in the case of Accounts or Collateral in the possession of any third
Person, by contacting Account


<PAGE>   16
                                       16


Debtors while a Notice of Enforcement is in effect or the third Person
possessing such Collateral for the purpose of making such a verification. The
Collateral Agent shall have the absolute right to share any information it gains
from such inspection or verification with any Secured Party (it being understood
that any such information shall be deemed to be "Information" subject to the
provisions of Section 9.12 of the Credit Agreement).

        SECTION 4.06. Taxes; Encumbrances. At its option, the Collateral Agent
may, upon reasonable prior notice to Grantors, discharge past due taxes,
assessments, charges, fees, Liens, security interests or other encumbrances at
any time levied or placed on the Collateral and not permitted under any Secured
Instrument, and may pay for the maintenance and preservation of the Collateral
to the extent any Grantor fails to do so as required by any Secured Instrument
or this Agreement, and each Grantor jointly and severally agrees to reimburse
the Collateral Agent on demand for any payment made or any expense incurred by
the Collateral Agent pursuant to the foregoing authorization; provided, however,
that nothing in this Section 4.06 shall be interpreted as excusing any Grantor
from the performance of, or imposing any obligation on the Collateral Agent or
any Secured Party to cure or perform, any covenants or other promises of any
Grantor with respect to taxes, assessments, charges, fees, liens, security
interests or other encumbrances and maintenance as set forth herein or in the
other Support Documents or any Secured Instrument.

        SECTION 4.07. Assignment of Security Interest. If at any time any
Grantor shall take a security interest in any property of an Account Debtor or
any other Person to secure payment and performance of an Account to the extent
permissible under the document granting a security interest, such Grantor shall
promptly assign such security interest to the Collateral Agent. Such assignment
need not be filed of public record unless necessary to continue the perfected
status of the security interest against creditors of and transferees from the
Account Debtor or other Person granting the security interest.

        SECTION 4.08. Continuing Obligations of the Grantors. Each Grantor shall
remain liable to observe and perform all the conditions and obligations to be
observed and performed


<PAGE>   17
                                       17


by it under each contract, agreement or instrument relating to the Collateral,
all in accordance with the terms and conditions thereof, and each Grantor
jointly and severally agrees to indemnify and hold harmless the Collateral Agent
and the Secured Parties from and against any and all liability for such
performance.

        SECTION 4.09. Use and Disposition of Collateral. None of the Grantors
shall make or permit to be made an assignment, pledge or hypothecation of the
Collateral or shall grant any other Lien in respect of the Collateral, except as
expressly permitted under each Secured Instrument. None of the Grantors shall
make, nor shall they permit to be made, any sale, conveyance, lease, assignment,
transfer or other disposition of any Collateral except as permitted under each
Secured Instrument and each Grantor shall remain at all times in possession of
the Collateral owned by it, except that unless and until the Collateral Agent
shall notify the Grantors that a Notice of Enforcement is in effect and that
while such Notice of Enforcement is in effect, the Grantors may use and dispose
of the Collateral in any lawful manner not inconsistent with the provisions of
this Agreement, or any other Support Document or any Secured Instrument. Without
limiting the generality of the foregoing, each Grantor agrees that it shall not
permit any Inventory to be in the possession or control of any warehouseman,
bailee, agent or processor at any time unless such warehouseman, bailee, agent
or processor shall have been notified of the Security Interest and shall have
agreed in writing to hold the Inventory subject to the Security Interest and the
instructions of the Collateral Agent and to waive and release any Lien held by
it with respect to such Inventory, whether arising by operation of law or
otherwise.

        SECTION 4.10. Limitation on Modification of Accounts. None of the
Grantors will, without the Collateral Agent's prior written consent, grant any
extension of the time of payment of any of the Accounts Receivable in the
aggregate, compromise, compound or settle the same for less than the full amount
thereof, release, wholly or partly, any Person liable for the payment thereof or
allow any credit or discount whatsoever thereon, other than extensions, credits,


<PAGE>   18
                                       18


discounts, compromises or settlements granted or made in the ordinary course of
business and consistent with its good faith business judgment.

        SECTION 4.11. Insurance. The Grantors, at their own expense, shall
maintain or cause to be maintained insurance covering physical loss or damage to
the Inventory and Equipment in accordance with the applicable requirements of
each Secured Instrument. Each Grantor irrevocably makes, constitutes and
appoints the Collateral Agent (and all officers, employees or agents designated
by the Collateral Agent) as such Grantor's true and lawful agent (and
attorney-in-fact) for the purpose, while a Notice of Enforcement is in effect,
of making, settling and adjusting claims in respect of Collateral under policies
of insurance, endorsing the name of such Grantor on any check, draft, instrument
or other item of payment for the proceeds of such policies of insurance and for
making all determinations and decisions with respect thereto. In the event that
any Grantor at any time or times shall fail to obtain or maintain any of the
policies of insurance required hereby or to pay any premium in whole or part
relating thereto, the Collateral Agent may, without waiving or releasing any
obligation or liability of the Grantors hereunder or any event that could result
in a Notice of Enforcement, in its sole reasonable discretion, obtain and
maintain such policies of insurance and pay such premium and take any other
actions with respect thereto as the Collateral Agent deems advisable. All sums
disbursed by the Collateral Agent in connection with this Section 4.11,
including reasonable attorneys' fees, court costs, expenses and other charges
relating thereto, shall be payable, upon demand, by the Grantors to the
Collateral Agent and shall be additional Obligations secured hereby.

        SECTION 4.12. Legend. Each Grantor shall upon written request legend, in
form and manner reasonably satisfactory to the Collateral Agent, its Accounts
Receivable and its books, records and, to the extent applicable, documents
evidencing or pertaining thereto with an appropriate reference to the fact that
such Accounts Receivable have been collaterally assigned to the Collateral Agent
for the benefit of the Secured Parties and that the Collateral Agent has a
security interest therein.


<PAGE>   19
                                       19


        SECTION 4.13. Covenants Regarding Patent, Trademark and Copyright
Collateral. (a) Each Grantor agrees that it will not, and it will exercise its
best efforts to ensure that its licensees will not, do any act, or omit to do
any act, whereby any Patent which is material to the conduct of such Grantor's
business may become invalidated or dedicated to the public, and agrees that it
shall continue to mark any products covered by a Patent with the relevant patent
number as necessary and sufficient to establish and preserve its maximum rights
under applicable patent laws.

        (b) Each Grantor (either itself or through its licensees or its
sublicensees) will, for each Trademark material to the conduct of such Grantor's
business, (i) maintain such Trademark in full force free from any claim of
abandonment or invalidity for non-use, (ii) maintain the quality of products and
services offered under such Trademark, (iii) display such Trademark with notice
of Federal or foreign registration to the extent necessary and sufficient to
establish and preserve its maximum rights under applicable law and (iv) not
knowingly use or knowingly permit the use of such Trademark in violation of any
third party rights.

        (c) Each Grantor (either itself or through licensees) will, for each
work material to the conduct of Grantor's business covered by a material
Copyright, continue to publish, reproduce, display, adopt and distribute the
work with appropriate copyright notice as necessary and sufficient to establish
and preserve its rights under applicable copyright laws.

        (d) Each Grantor shall notify the Collateral Agent promptly if it knows
that any Patent, Trademark or Copyright material to the conduct of the business
of the Grantors (taken as a whole) may reasonably be expected to become
abandoned, lost or dedicated to the public, or of any material adverse
determination or development (including the institution of, or any such
determination or development in, any proceeding in the United States Patent and
Trademark Office, United States Copyright Office or any court or similar office
of any country) regarding such Grantor's


<PAGE>   20
                                       20


ownership of any such Patent, Trademark or Copyright, its right to register the
same, or to keep and maintain the same.

        (e) In the event that any Grantor shall, either itself or through any
agent, employee, licensee or designee, file an application for any Patent,
Trademark or Copyright (or for the registration of any Trademark or Copyright)
with the United States Patent and Trademark Office, United States Copyright
Office or any office or agency in any political subdivision of the United States
or in any other country or any political subdivision thereof, such Grantor shall
promptly thereafter inform the Collateral Agent of such action, and, upon
request of the Collateral Agent, execute and deliver any and all agreements,
instruments, documents and papers as the Collateral Agent may reasonably request
to evidence the Collateral Agent's security interest in such Patent, Trademark
or Copyright, and such Grantor hereby appoints the Collateral Agent as its
attorney-in-fact to execute and file such writings for the foregoing purposes,
all acts of such attorney being hereby ratified and confirmed; such power, being
coupled with an interest, is irrevocable.

        (f) Each Grantor will take all necessary steps that are consistent with
the practice in any proceeding before the United States Patent and Trademark
Office, United States Copyright Office or any office or agency in any political
subdivision of the United States or in any other country or any political
subdivision thereof, to maintain and pursue each material application relating
to the Patents, Trademarks and/or Copyrights (excluding applications which a
Grantor abandons pursuant to good faith business considerations) (and to obtain
the relevant grant or registration) and to maintain each issued Patent and each
registration of the Trademarks and Copyrights that is material to the conduct of
the business of the Grantors (taken as a whole), including timely filings of
applications for renewal, affidavits of use, affidavits of incontestability and
payment of maintenance fees, and, if consistent with good business judgment, to
initiate opposition, interference and cancelation proceedings against third
parties.

        (g) In the event that any Grantor has reason to


<PAGE>   21
                                       21


believe that any Collateral consisting of a Patent, Trademark or Copyright
material to the conduct of the business of the Grantors (taken as a whole) has
been or is about to be infringed, misappropriated or diluted by a third party in
any material respect, such Grantor promptly shall notify the Collateral Agent
and shall, if consistent with good business judgment, promptly sue for
infringement, misappropriation or dilution and to recover any and all damages
for such infringement, misappropriation or dilution, and take such other actions
as are appropriate under the circumstances to protect such Collateral.

        (h) While a Notice of Enforcement is in effect, if requested by the
Collateral Agent, each Grantor shall use reasonable efforts to obtain all
requisite consents or approvals by the licensor of each Copyright License,
Patent License or Trademark License to effect the assignment of all of such
Grantor's right, title and interest thereunder to the Collateral Agent or its
designee.

                                    ARTICLE V

                                Power of Attorney

        Each Grantor irrevocably makes, constitutes and appoints the Collateral
Agent (and all officers, employees or agents designated by the Collateral Agent)
as such Grantor's true and lawful agent and attorney-in-fact, and in such
capacity the Collateral Agent shall have the right, with power of substitution
for each Grantor and in each Grantor's name or otherwise, for the use and
benefit of the Collateral Agent and the Secured Parties, while a Notice of
Enforcement is in effect (a) to receive, endorse, assign and/or deliver any and
all notes, acceptances, checks, drafts, money orders or other evidences of
payment relating to the Collateral or any part thereof; (b) to demand, collect,
receive payment of, give receipt for and give discharges and releases of all or
any of the Collateral; (c) to sign the name of any Grantor on any invoice or
bill of lading relating to any of the Collateral; (d) to send verifications of
Accounts Receivable to any Account Debtor;


<PAGE>   22
                                       22


        (e) to commence and prosecute any and all suits, actions or proceedings
at law or in equity in any court of competent jurisdiction to collect or
otherwise realize on all or any of the Collateral or to enforce any rights in
respect of any Collateral; (f) to settle, compromise, compound, adjust or defend
any actions, suits or proceedings relating to all or any of the Collateral; (g)
to notify, or to require any Grantor to notify, Account Debtors to make payment
directly to the Collateral Agent; and (h) to use, sell, assign, transfer,
pledge, make any agreement with respect to or otherwise deal with all or any of
the Collateral, and to do all other acts and things necessary to carry out the
purposes of this Agreement, as fully and completely as though the Collateral
Agent were the absolute owner of the Collateral for all purposes, in each case
in a manner not inconsistent with the terms of this Agreement and on terms that
are commercially reasonable and in compliance with any mandatory requirements of
applicable law; provided, however, that nothing herein contained shall be
construed as requiring or obligating the Collateral Agent or any Secured Party
to make any commitment or to make any inquiry as to the nature or sufficiency of
any payment received by the Collateral Agent or any Secured Party, or to present
or file any claim or notice, or to take any action with respect to the
Collateral or any part thereof or the moneys due or to become due in respect
thereof or any property covered thereby, and no action taken or omitted to be
taken by the Collateral Agent or any Secured Party with respect to the
Collateral or any part thereof shall give rise to any defense, counterclaim or
offset in favor of any Grantor or to any claim or action against the Collateral
Agent or any Secured Party. It is understood and agreed that the appointment of
the Collateral Agent as the agent and attorney-in-fact of the Grantors for the
purposes set forth above is coupled with an interest and is irrevocable. The
provisions of this Section shall in no event relieve any Grantor of any of its
obligations hereunder or under any other Support Document or any Secured
Instrument with respect to the Collateral or any part thereof or impose any
obligation on the Collateral Agent or any Secured Party to proceed in any
particular manner with respect to the Collateral or any part thereof, or in any
way limit the


<PAGE>   23
                                       23


exercise by the Collateral Agent or any Secured Party of any other or further
right which it may have on the date of this Agreement or hereafter, whether
hereunder, under any other Support Document or any Secured Instrument, by law or
otherwise.

                                   ARTICLE VI

                                    Remedies

        SECTION 6.01. Remedies upon Default. While a Notice of Enforcement is in
effect, each Grantor agrees to deliver each item of Collateral to the Collateral
Agent forthwith on demand to the extent reasonably practicable, and it is agreed
that the Collateral Agent shall have the right to take any of or all the
following actions at the same or different times (subject to any mandatory
requirements of law and standards of commercial reasonableness that cannot be
waived by contract): (a) with respect to any Collateral consisting of
Intellectual Property, on demand, to cause the Security Interest to become an
assignment, transfer and conveyance of any of or all such Collateral by the
applicable Grantors to the Collateral Agent, or to license or sublicense,
whether general, special or otherwise, and whether on an exclusive or
non-exclusive basis, any such Collateral throughout the world on such terms and
conditions and in such manner as the Collateral Agent shall determine (other
than in violation of any then-existing licensing arrangements to the extent that
waivers cannot be obtained) and (b) with or without legal process and with or
without prior notice or demand for performance, to take possession of the
Collateral and to enter any premises owned or leased by the Grantors where the
Collateral may be located for the purpose of taking possession of or removing
the Collateral and, generally, to exercise any and all rights afforded to a
secured party under the Uniform Commercial Code or other applicable law. Without
limiting the generality of the foregoing, each Grantor agrees that the
Collateral Agent shall have the right, subject to the mandatory requirements of
applicable law, to sell or otherwise dispose of all or any part of the
Collateral, at public or private sale or at


<PAGE>   24
                                       24


any broker's board or on any securities exchange, for cash, upon credit or for
future delivery as the Collateral Agent shall deem appropriate and commercially
reasonable. The Collateral Agent shall be authorized at any such sale (if it
deems it advisable to do so) to restrict the prospective bidders or purchasers
to Persons who will represent and agree that they are purchasing the Collateral
for their own account for investment and not with a view to the distribution or
sale thereof, and upon consummation of any such sale the Collateral Agent shall
have the right to assign, transfer and deliver to the purchaser or purchasers
thereof the Collateral so sold. Each such purchaser at any such sale shall hold
the property sold absolutely, free from any claim or right on the part of any
Grantor, and each Grantor hereby waives (to the extent permitted by law) all
rights of redemption, stay and appraisal which such Grantor now has or may at
any time in the future have under any rule of law or statute now existing or
hereafter enacted.

        The Collateral Agent shall give the Grantors 10 days' written notice
(which each Grantor agrees is reasonable notice within the meaning of Section
9-504(3) of the Uniform Commercial Code as in effect in the State of New York or
its equivalent in other jurisdictions) of the Collateral Agent's intention to
make any sale of Collateral. Such notice, in the case of a public sale, shall
state the time and place for such sale and, in the case of a sale at a broker's
board or on a securities exchange, shall state the board or exchange at which
such sale is to be made and the day on which the Collateral, or portion thereof,
will first be offered for sale at such board or exchange. Any such public sale
shall be held at such time or times within ordinary business hours and at such
place or places as the Collateral Agent may fix and state in the notice (if any)
of such sale. At any such sale, the Collateral, or portion thereof, to be sold
may be sold in one lot as an entirety or in separate parcels, as the Collateral
Agent may (in its sole and absolute discretion) determine. The Collateral Agent
shall not be obligated to make any sale of any Collateral if it shall determine
not to do so, regardless of the fact that notice of sale of such Collateral
shall have been given. The Collateral Agent may, without notice or publication,
adjourn any public or private sale or cause the same to be adjourned from time
to time by announcement at the time and place fixed for sale, and such sale may,
without further


<PAGE>   25
                                       25


notice, be made at the time and place to which the same was so adjourned. In
case any sale of all or any part of the Collateral is made on credit or for
future delivery, the Collateral so sold may be retained by the Collateral Agent
until the sale price is paid by the purchaser or purchasers thereof, but the
Collateral Agent shall not incur any liability in case any such purchaser or
purchasers shall fail to take up and pay for the Collateral so sold and, in case
of any such failure, such Collateral may be sold again upon like notice. Subject
to Section 9.05 of the Collateral Agency and Intercreditor Agreement, at any
public (or, to the extent permitted by applicable law, private) sale made
pursuant to this Section, any Secured Party may bid for or purchase, free from
any right of redemption, stay or appraisal on the part of any Grantor (all said
rights being also hereby waived and released), the Collateral or any part
thereof offered for sale and such Secured Party may, upon compliance with the
terms of sale, hold, retain and dispose of such property without further
accountability to any Grantor therefor. For purposes hereof, a written agreement
to purchase the Collateral or any portion thereof shall be treated as a sale
thereof; the Collateral Agent shall be free to carry out such sale pursuant to
such agreement and no Grantor shall be entitled to the return of the Collateral
or any portion thereof subject thereto, notwithstanding the fact that after the
Collateral Agent shall have entered into such an agreement the applicable Notice
of Enforcement shall have been rescinded in accordance with the terms of the
Collateral Agency and Intercreditor Agreement remedied and the Obligations paid
in full. As an alternative to exercising the power of sale herein conferred upon
it, the Collateral Agent may proceed by a suit or suits at law or in equity to
foreclose this Agreement and to sell the Collateral or any portion thereof
pursuant to a judgment or decree of a court or courts having competent
jurisdiction or pursuant to a proceeding by a court-appointed receiver.

        SECTION 6.02. Application of Proceeds. The Collateral Agent shall apply
promptly the proceeds of any collection or sale of the Collateral, as well as
any Collateral consisting of cash, as provided in the Collateral Agency and
Intercreditor Agreement.


<PAGE>   26
                                       26


        Upon any sale of the Collateral by the Collateral Agent (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the Collateral Agent or of the officer making the sale shall be a
sufficient discharge to the purchaser or purchasers of the Collateral so sold
and such purchaser or purchasers shall not be obligated to see to the
application of any part of the purchase money paid over to the Collateral Agent
or such officer or be answerable in any way for the misapplication thereof.

        SECTION 6.03. Grant of License to Use Intellectual Property. For the
purpose of enabling the Collateral Agent to exercise rights and remedies under
this Article at such time as the Collateral Agent shall be lawfully entitled to
exercise such rights and remedies, each Grantor hereby grants to the Collateral
Agent an irrevocable, non-exclusive license (exercisable without payment of
royalty or other compensation to the Grantors) to use, license or sub-license
any of the Collateral consisting of Intellectual Property now owned or hereafter
acquired by such Grantor (to the extent not prohibited by the terms of any
license agreement pursuant to which such Grantor is a licensee), and wherever
the same may be located, and including in such license reasonable access to all
media in which any of the licensed items may be recorded or stored and to all
computer software and programs used for the compilation or printout thereof. The
use of such license by the Collateral Agent shall be exercised, at the option of
the Collateral Agent, while a Notice of Enforcement is in effect; provided that
any license, sub-license or other transaction entered into by the Collateral
Agent in accordance herewith shall be binding upon the Grantors notwithstanding
whether such Notice of Enforcement is subsequently rescinded in accordance with
the terms of the Collateral Agency and Intercreditor Agreement.

                                   ARTICLE VII

                                  Miscellaneous

        SECTION 7.01. Notices. All communications and notices hereunder shall
(except as otherwise expressly permitted herein) be in writing and given as
provided in Section 11.01


<PAGE>   27
                                       27


of the Collateral Agency and Intercreditor Agreement. All communications and
notices hereunder to any Grantor shall be given to it at its address or telecopy
number set forth on Schedule I, with a copy to the Borrower.

        SECTION 7.02. Security Interest Absolute. All rights of the Collateral
Agent hereunder, the Security Interest and all obligations of the Grantors
hereunder shall be absolute and unconditional irrespective of (a) any lack of
validity or enforceability of any Support Document or Secured Instrument, any
other Loan Document, any agreement with respect to any of the Obligations or any
other agreement or instrument relating to any of the foregoing, (b) any change
in the time, manner or place of payment of, or in any other term of, all or any
of the Obligations, or any other amendment or waiver of or any consent to any
departure from any Support Document or Secured Instrument, any other Loan
Document or any other agreement or instrument, (c) any exchange, release or
non-perfection of any Lien on other collateral, or any release or amendment or
waiver of or consent under or departure from any guarantee, securing or
guaranteeing all or any of the Obligations, or (d) any other circumstance that
might otherwise constitute a defense available to, or a discharge of, any
Grantor in respect of the Obligations or this Agreement.

        SECTION 7.03. Survival of Agreement. All covenants, agreements,
representations and warranties made by any Grantor herein and in the
certificates or other instruments prepared or delivered in connection with or
pursuant to this Agreement shall be considered to have been relied upon by the
Secured Parties and shall survive the extension of credit by any Secured Party,
and the execution and delivery to the Secured Parties of any notes evidencing
such extensions of credit, regardless of any investigation made by the Secured
Parties or on their behalf, and shall continue in full force and effect until
this Agreement shall terminate.

        SECTION 7.04. Binding Effect; Several Agreement. This Agreement shall
become effective as to any Grantor when a counterpart hereof executed on behalf
of such Grantor shall


<PAGE>   28
                                       28


have been delivered to the Collateral Agent and a counterpart hereof shall have
been executed on behalf of the Collateral Agent, and thereafter shall be binding
upon such Grantor and the Collateral Agent and their respective successors and
assigns, and shall inure to the benefit of such Grantor, the Collateral Agent
and the other Secured Parties and their respective successors and assigns,
except that no Grantor shall have the right to assign or transfer its rights or
obligations hereunder or any interest herein or in the Collateral (and any such
assignment or transfer shall be void) except as expressly contemplated by this
Agreement and the other Support Documents. This Agreement shall be construed as
a separate agreement with respect to each Grantor and may be amended, modified,
supplemented, waived or released with respect to any Grantor without the
approval of any other Grantor and without affecting the obligations of any other
Grantor hereunder.

        SECTION 7.05. Successors and Assigns. Whenever in this Agreement any of
the parties hereto is referred to, such reference shall be deemed to include the
successors and assigns of such party; and all covenants, promises and agreements
by or on behalf of any Grantor or the Collateral Agent that are contained in
this Agreement shall bind and inure to the benefit of their respective
successors and assigns.

        SECTION 7.06. Collateral Agent's Fees and Expenses; Indemnification. (a)
Each Grantor jointly and severally agrees to pay upon demand to the Collateral
Agent the amount of any and all reasonable expenses, including the reasonable
fees, disbursements and other charges of its counsel and of any experts or
agents, which the Collateral Agent may incur in connection with (i) the
administration of this Agreement, (ii) the custody or preservation of, or the
sale of, collection from or other realization upon any of the Collateral, (iii)
the exercise, enforcement or protection of any of the rights of the Collateral
Agent hereunder or (iv) the failure of any Grantor to perform or observe any of
the provisions hereof.

        (b) Without limitation of its indemnification obligations under the
other Support Documents, each Grantor jointly and severally agrees to indemnify
the Collateral Agent and the other Indemnitees against, and hold each of


<PAGE>   29
                                       29


them harmless from, any and all losses, claims, damages, liabilities and related
expenses, including reasonable fees, disbursements and other charges of counsel,
incurred by or asserted against any of them arising out of, in any way connected
with, or as a result of, the execution, delivery or performance of this
Agreement or any claim, litigation, investigation or proceeding relating hereto
or to the Collateral, whether or not any Indemnitee is a party thereto; provided
that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, claims, damages, liabilities or related expenses have resulted
from the gross negligence or willful misconduct of such Indemnitee.

        (c) Any such amounts payable as provided hereunder shall be additional
Obligations secured hereby and by the other Security Documents. The provisions
of this Section 7.06 shall remain operative and in full force and effect
regardless of the termination of this Agreement or any other Support Document or
any Secured Instrument, the consummation of the transactions contemplated
hereby, the repayment of any of the Obligations, the invalidity or
unenforceability of any term or provision of this Agreement or any other Support
Document, or any investigation made by or on behalf of the Collateral Agent or
any other Secured Party. All amounts due under this Section 7.06 shall be
payable on written demand therefor.

        SECTION 7.07. GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

        SECTION 7.08. Waivers; Amendment. (a) No failure or delay of the
Collateral Agent in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Collateral Agent hereunder
and of the Collateral Agent, and the Secured Parties under the other Support
Documents and the Secured


<PAGE>   30
                                       30


Instruments are cumulative and are not exclusive of any rights or remedies that
they would otherwise have. No waiver of any provisions of this Agreement or any
other Support Document or consent to any departure by any Grantor therefrom
shall in any event be effective unless the same shall be permitted by paragraph
(b) below, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice to or demand on
any Grantor in any case shall entitle such Grantor or any other Grantor to any
other or further notice or demand in similar or other circumstances.

        (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to an agreement or agreements in writing
entered into by the Collateral Agent and the Grantor or Grantors with respect to
which such waiver, amendment or modification is to apply, subject to any
consents required in accordance with Section 11.02 of the Collateral Agency and
Intercreditor Agreement.

        SECTION 7.09. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER SUPPORT
DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER SUPPORT DOCUMENTS, AS
APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN
THIS SECTION 7.09.

        SECTION 7.10. Severability. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected


<PAGE>   31
                                       31


or impaired thereby (it being understood that the invalidity of a particular
provision in a particular jurisdiction shall not in and of itself affect the
validity of such provision in any other jurisdiction). The parties shall
endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

        SECTION 7.11 Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute but one contract (subject to Section 7.04), and
shall become effective as provided in Section 7.04. Delivery of an executed
signature page to this Agreement by facsimile transmission shall be effective as
delivery of a manually executed counterpart hereof.

        SECTION 7.12. Headings. Article and Section headings used herein are for
the purpose of reference only, are not part of this Agreement and are not to
affect the construction of, or to be taken into consideration in interpreting,
this Agreement.

        SECTION 7.13. Jurisdiction; Consent to Service of Process. (a) Each
Guarantor hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of the Supreme Court of the State of
New York sitting in New York County and of the United States District Court of
the Southern District of New York, and any appellate court from any thereof, in
any action or proceeding arising out of or relating to this Agreement or any
other Support Document, or for recognition or enforcement of any judgment, and
each of the parties hereto hereby irrevocably and unconditionally agrees that
all claims in respect of any such action or proceeding may be heard and
determined in such New York State or, to the extent permitted by law, in such
Federal court. Each of the parties hereto agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement or any other Support Document shall affect any right
that the Collateral Agent or any Secured Party may otherwise have to bring any
action or proceeding relating to this Agreement or

<PAGE>   32
                                       32

any other Support Document against any Grantor or its properties in the courts
of any jurisdiction.

        (b) Each Grantor hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or the other Support Document in
any New York State or Federal court. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

        (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 7.01. Nothing in this
Agreement or any other Support Document will affect the right of any party to
this Agreement to serve process in any other manner permitted by law.

        SECTION 7.14. Termination. This Agreement and the Security Interest
shall terminate when all the Obligations have been indefeasibly paid in full and
all Secured Instrument Commitments shall have terminated, at which time the
Collateral Agent shall execute and deliver to the Grantors, at the Grantors'
expense, all Uniform Commercial Code termination statements and similar
documents which the Grantors shall reasonably request to evidence such
termination. Any execution and delivery of termination statements or documents
pursuant to this Section 7.14 shall be without recourse to or warranty by the
Collateral Agent (except to the extent that any losses, claims, damages,
liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of the Collateral Agent). Subject to Section
9.03 of the Collateral Agency and Intercreditor Agreement, a Grantor shall
automatically be released from its obligations hereunder and the Security
Interest in the Collateral of such Grantor shall be automatically released in
the event that all the capital stock of such Grantor


<PAGE>   33
                                       33


shall be sold, transferred or otherwise disposed of to a Person that is not the
Parent, Holdings or a Grantor in a transaction that does not violate any Secured
Instrument.

        SECTION 7.15. Additional Grantors. Upon execution and delivery by the
Collateral Agent and a Subsidiary Loan Party of an instrument in the form of
Annex 1 hereto, such Subsidiary Loan Party shall become a Grantor hereunder with
the same force and effect as if originally named as a Grantor herein. The
execution and delivery of any such instrument shall not require the consent of
any Grantor hereunder. The rights and obligations of each Grantor hereunder
shall remain in full force and effect notwithstanding the addition of any new
Grantors as a party to this Agreement.

        IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement
as of the day and year first above written.

Instrument. Section 7.15 of Security Agreement provides that additional
Subsidiary Loan Parties may become Grantors under the Security Agreement by
execution and delivery of an instrument in the form of this Supplement. The
undersigned Subsidiary Loan Party (the "New Grantor") is executing this
Supplement to become a Grantor under the Security Agreement in order to induce
the Secured Parties to make additional loans under the applicable Secured
Instruments and as consideration for loans previously made under the Secured

and the New Grantor hereby (a) agrees to all the terms and provisions of the
Security Agreement applicable to it as a Grantor thereunder and (b) represents
and warrants that the representations and warranties made by it as a Grantor
thereunder are true and correct on and as of the date hereof. In furtherance of
the foregoing, the New Grantor, as security for the payment and performance in
full of the Obligations (as defined in the Collateral Agency and Intercreditor
Agreement), does hereby create and grant to the Collateral Agent, its successors
and assigns, for the benefit of the Secured Parties, their successors and
assigns, a security interest in and lien on all of the New Grantor's right,
title and interest in and to the Collateral (as defined in the Collateral Agency
and Intercreditor Agreement) of the New Grantor. Each reference to a "Grantor"
in the Security Agreement shall be deemed to include the New Grantor. The
Security Agreement is hereby incorporated herein by reference.

Agent and the other Secured Parties that this Supplement has been duly
authorized, executed and delivered by it and constitutes its legal, valid and
binding obligation, enforceable against it in accordance with its terms.

        SECTION 3. This Supplement may be executed in counterparts (and by
different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a
single contract. This Supplement shall become effective when the Collateral
Agent shall have received counterparts of this Supplement that, when taken
together, bear the signatures of the New Grantor and the Collateral Agent.
Delivery of an executed signature page to this Supplement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart
of this Supplement.

        SECTION 4. The New Grantor hereby represents and warrants that (a) set
forth on Schedule I attached hereto is a true and correct schedule of the
location of any and all Collateral of the New Grantor as of the date hereof and

Supplement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein and in the Security Agreement shall not in any way be affected or
impaired thereby (it being understood that the invalidity of a particular
provision in a particular jurisdiction shall not in and of itself affect the
validity of such provision in any other jurisdiction). The parties hereto shall
endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

        SECTION 8. All communications and notices hereunder shall be in writing
and given as provided in Section 7.01 of the Security Agreement. All
communications and notices hereunder to the New Grantor shall be given to it at

Obligations of such Borrower Company as and when the same shall become due and
payable in accordance with the terms thereof, or affect the relative rights of
the Subordinated Creditors and the other creditors of the Borrower Company
(other than their Senior Creditors).

Obligations owed to it upon demand of the Collateral Agent, in default of which
the Collateral Agent or other authorized representative of the Senior Creditors
is hereby irrevocably authorized so to file in order to effectuate the
provisions hereof. This Section shall not be construed to permit any
Subordinated Creditor to retain any payment received by it in respect of a
Subordinated Obligation that such Subordinated Creditor is not entitled to
receive and retain under any other provision of this Agreement.

                SECTION 3.3. No Waiver. No right of any Senior Creditor to

Subordinated Creditor agrees that, except for claims submitted in any proceeding
contemplated by Section 3.2 hereof, it will not exercise any remedies or take
any action or proceeding to enforce any Subordinated Obligation if the payment
of such Subordinated Obligation is then prohibited by Section 2.3 or 2.4, and
each Subordinated Creditor further agrees not to file, or to join with any other
creditors of any Borrower Company in filing, any petition commencing any
bankruptcy, insolvency, reorganization, arrangement or receivership proceeding
or any assignment for the benefit of creditors against or in respect of any
Borrower Company or any other marshaling of the assets and liabilities of any
Borrower Company. Each Subordinated Creditor further agrees, to the fullest
extent permitted under applicable law, that it will not cause any Borrower
Company to file any such petition, commence any such proceeding or make any such
assignment referred to above until all Senior Obligations have been paid in
full.

                SECTION 3.5. Transfer of Subordinated Obligations. Each

Section 3.5, as though named herein as a Subordinated Creditor.

                SECTION 3.6. Obligations Hereunder Not Affected. (a) All rights
and interests of the Senior Creditors hereunder, and all agreements and
obligations of the Subordinated Creditors hereunder, shall remain in full force
and effect irrespective of:

                (i) any lack of validity or enforceability of any Support
        Document or Secured Instrument;

                (ii) any change in the time, manner or place of payment of, or
        in any other term of, all or any of the Senior Obligations, or any other
        amendment or waiver of or consent to departure from the Credit Agreement
        or any other Senior Creditor Document (other than this Agreement);

                (iii) any exchange, release or nonperfection of any security
        interest in any collateral, or any release or amendment or waiver of or
        consent to departure from any guarantee, in respect of all or any of the
        Senior Obligations; or

                (iv) any other circumstance that might otherwise constitute a
        defense available to, or a discharge of, any Borrower Company in respect
        of its Senior Obligations or of any Subordinated Creditor in respect of
        this Agreement.

                                  MISCELLANEOUS

                SECTION 5.1. Notices. All communications and notices hereunder
shall be in writing and shall be given as provided in Section 11.01 of the
Collateral Agency and Intercreditor Agreement; provided that any communication
or notice hereunder to any Subordinated Creditor shall be given to it at the

warranties, covenants, promises and agreements by or on behalf of any
Subordinated Creditor that are contained in this Agreement shall bind its
successors and assigns and inure to the benefit of the Senior Creditors and the
successors and assigns of the Senior Creditors. Each Subordinated Creditor
agrees that it shall not assign or delegate any of its obligations under this
Agreement without the prior written consent of the Collateral Agent, and any
attempted assignment or delegation without such consent shall be void and of no
effect.

                SECTION 5.3. Governing Law; Jurisdiction; Consent to Service of
Process. (a) This Agreement shall be construed in accordance with and governed
by the law of the State of New York.

                (b) Each Subordinated Creditor hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New

arising out of or relating to this Agreement or any other Senior Creditor

<PAGE>   11
                                       11


the extent permitted by law, in such Federal court. Each of the parties hereto
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that the Collateral Agent or any other Senior Creditor may otherwise have

Subordinated Creditor or its properties in the courts of any jurisdiction.

                (c) Each Subordinated Creditor hereby irrevocably and

proceeding in any such court.

                (d) Each Subordinated Creditor hereby irrevocably consents to

this Agreement will affect the right of any party to this Agreement to serve
process in any other manner permitted by law.

                SECTION 5.4. Waivers; Amendment. No failure or delay of any
Senior Creditor in exercising any right or power hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power by any Senior Creditor preclude any other or further exercise thereof or
the exercise of any other right or power. The rights and remedies of the Senior
Creditors hereunder and under the other documents and instruments creating or
securing their respective Senior Obligations are cumulative and are not
exclusive of any other rights or remedies provided by law. Neither this
Agreement nor any provision hereof may be waived, amended or modified except

(WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A)
CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE
EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES
THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS
AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION.

                SECTION 5.6. Severability. In the event any one or more of the
provisions contained in this Agreement should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby. The parties shall endeavor in good faith negotiations to
replace any invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

                SECTION 5.7. Counterparts. This Agreement may be executed in two
or more counterparts, each of which shall constitute an original but all of
which, when taken together, shall constitute but one instrument; provided that
this Agreement shall be construed as a separate agreement with respect to each
Subordinated Creditor and may be amended, modified, supplemented, waived or
released with respect to any Subordinated Creditor without the approval of any
other Subordinated Creditor and without affecting the obligations of any other
Subordinated Creditor hereunder. This Agreement shall be effective with respect
to any Subordinated Creditor when a counterpart hereof (or of an


<PAGE>   13
                                       13


instrument executed as provided in Section 5.9 below) which bears the signature

and delivery by the Agent and an Affiliate of Holdings or the Borrower or a
Subsidiary Loan Party of an instrument in the form of Annex 1 attached thereto,
such Affiliate or Subsidiary Loan Party shall become a Subordinated Creditor
hereunder with the same force and effect as if originally named as a
Subordinated Creditor herein. The execution and delivery of any such instrument
shall not require the consent of any other Subordinated Creditor hereunder. The
rights and obligations of each Subordinated Creditor herein shall remain in full
force and effect notwithstanding the addition of any Subordinated Creditor as a
party to this Agreement.

                SECTION 5.10. Termination. Subject to Section 3.6(b), this
Agreement shall terminate upon the termination of all Secured Instrument
Commitments and the payment in full of the Obligations.

                IN WITNESS WHEREOF, the Parent, Holdings, each Subsidiary, each
License Subsidiary, the Borrower and the Collateral Agent have caused this
Agreement to be duly executed by their respective authorized representatives as

                Agreement dated as of September 17, 1999, among CRICKET
                COMMUNICATIONS, INC., a Delaware corporation ("Holdings"),
                CRICKET WIRELESS COMMUNICATIONS, INC., a Delaware corporation
                (the "Borrower"), LEAP WIRELESS INTERNATIONAL, INC., a Delaware
                corporation (the "Parent"), each subsidiary of the Borrower
                listed on Schedule I hereto (each a "Subsidiary", and,
                collectively, the "Subsidiaries"), each subsidiary of the Parent
                listed on Schedule I hereto (each a "License Subsidiary", and,
                collectively, the "License Subsidiaries"; each Subsidiary, each

                the Secured Parties.


        A. Reference is made to the (a) Collateral Agency and Intercreditor
Agreement (as defined in the Subordination Agreement) and (b) the Subordination
Agreement).

        B. Capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to such terms in the Subordination Agreement.

        C. The Subordinated Creditors and the Borrower have entered into the
Subordination Agreement in order to induce the Secured Parties to make loans
under the applicable Secured Instrument. Section 5.9 of the Subordination
Agreement provides that Affiliates of Holdings or the Borrower and additional
Subsidiary Loan Parties may become Subordinated Creditors under the
Subordination Agreement by execution and delivery of an instrument in the form
of this Supplement. The undersigned Affiliate of Holdings or the Borrower or

Subordination Agreement in order to induce the Secured Parties to make
additional loans under the applicable Secured Instruments


<PAGE>   17
                                       17


and as consideration for loans previously made under the Secured Instruments.

        Accordingly, the Collateral Agent and the New Subordinated Creditor
agree as follows:

        SECTION 1. In accordance with Section 5.9 of the Subordination
Agreement, the New Subordinated Creditor by its signature below becomes a
Subordinated Creditor under the Subordination Agreement with the same force and
effect as if originally named therein as a Subordinated Creditor and the New
Subordinated Creditor hereby (a) agrees to all the terms and provisions of the
Subordination Agreement applicable to it as a Subordinated Creditor thereunder
and (b) represents and warrants that the representations and warranties made by
it as a Subordinated Creditor thereunder are true and correct on and as of the
date hereof except for representations and warranties which by their terms refer
to a specific date. Each reference to a "Subordinated Creditor" in the
Subordination Agreement shall be deemed to include the New Subordinated
Creditor. The Subordination Agreement is hereby incorporated herein by
reference.

        SECTION 2. The New Subordinated Creditor represents and warrants to the
Collateral Agent and the other Secured Parties that this Supplement has been
duly authorized, executed and delivered by it and constitutes its legal, valid
and binding obligation, enforceable against it in accordance with its terms,
subject to applicable bankruptcy, insolvency, moratorium or other laws affecting
creditors' rights generally and subject to general principles of equity
regardless of whether considered in a proceeding in equity or at law.

        SECTION 3. This Supplement may be executed in counterparts, each of
which shall constitute an original, but all of which when taken together shall
constitute a single contract. This Supplement shall become effective when the
Collateral Agent shall have received counterparts of this Supplement that, when
taken together, bear the signatures of the New Subordinated Creditor and the
Collateral Agent. Delivery of an executed signature page to


<PAGE>   18
                                       18


this Supplement by facsimile transmission shall be as effective as delivery of a
manually executed counterpart of this Supplement.

        SECTION 4. Except as expressly supplemented hereby, the Subordination
Agreement shall remain in full force and effect.

        SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

        SECTION 6. In case any one or more of the provisions contained in this
Supplement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein and in the Subordination Agreement shall not in any way be affected or
impaired thereby (it being understood that the invalidity of a particular
provision hereof in a particular jurisdiction shall not in and of itself affect
the validity of such provision in any other jurisdiction). The parties hereto
shall endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

        SECTION 7. All communications and notices hereunder shall be in writing
and given as provided in Section 5.1 of the Subordination Agreement. All
communications and notices hereunder to the New Subordinated Creditor shall be
given to it at the address set forth under its signature below, with a copy to
the Borrower.

        SECTION 8. The New Subordinated Creditor agrees to reimburse the
Collateral Agent for its reasonable out-of-pocket expenses in connection with
this Supplement, including the reasonable fees, disbursements and other charges
of counsel for the Collateral Agent.

        IN WITNESS WHEREOF, the New Subordinated Creditor and


<PAGE>   19
                                       19

     2.2. CRICKET NOTICE. No sooner than the date seven (7) months before the
scheduled Delivery Date but not later than six (6) months before the scheduled
Delivery Date set forth in the Ericsson First Notice, Cricket shall provide
notice (the "Cricket Notice") to Ericsson which notice shall contain each of the
following: (i) if Cricket contends the financing terms and conditions at the
time of the Cricket Notice offered by its Primary Vendor have materially changed
in Cricket's favor, Cricket shall notify Ericsson that it is requesting
comparable financing terms and conditions; and (ii) the price of Products,
Equipment and Systems as established pursuant to Section 3.5 below; if prices
have been agreed upon in the definitive agreement and Cricket contends the
financing terms and conditions at the time of the Cricket Notice offered by its
Primary Vendor have materially changed in Cricket's favor or, if no prices have
been agreed upon in the Definitive Agreements; and (iii) Cricket shall provide
Ericsson with a copy of its current business plan and financial information, so
as to enable Ericsson to evaluate and make an informed business decision with
regard to whether it wishes to offer the proposed vendor financing. The Cricket
Notice shall provide reasonable specificity as to the requested information.
Cricket further agrees to reasonably cooperate with Ericsson by providing any
non-confidential information reasonably requested by Vendor for purposes of
verifying the information contained in Cricket's Notice, and, if requested by
Ericsson, will allow the audit procedure set forth in the Master Agreement to be
followed to verify the pricing set forth in the Cricket Notice.

     2.3. NOTICE OF TERMINATION. Through and including the date thirty (30)
calendar days after receipt of the Cricket Notice, Ericsson shall have the
option to terminate this Memorandum of Agreement and Definitive Agreements if
any of the following occur: (i) Ericsson's Board of Directors does not approve
the financing contemplated by Section 3.4; (ii) if Equipment or System prices
have changed from those set forth in the Definitive Agreements as provided in

<PAGE>   4

set forth in the Definitive Agreements as provide in Section 3.4, and Ericsson
disapproves any such proposed new terms; or (iv) if Cricket's business plan or
financial information as provided by Cricket do not meet Ericsson's
satisfaction. Ericsson shall use commercial reasonable efforts to: (a) satisfy
the milestones; and (b) have its Board of Directors approve the financing. If
any of the items (i) through (iv) above within this Section occur, Ericsson may
terminate this Memorandum of Agreement and the Definitive Agreements by
providing written notice to Cricket (the "Ericsson Second Notice"). If Ericsson
exercises its termination option, the parties shall be relieved of all further
rights and obligations under this Memorandum of Agreement and the Definitive
Agreements; and Ericsson shall have no liability in connection with such
termination. If Ericsson fails to give the Ericsson Second Notice on or before
the date thirty (30) calendar days after receipt of the Cricket Notice, Cricket
shall give Ericsson notice of its failure to give the Ericsson Second Notice
and, if Ericsson has not given the Ericsson Second Notice within five (5)
business days after notice that the Ericsson Second Notice is late, then
Ericsson shall have been deemed to have terminated its obligations hereunder,
and the Memorandum of Agreement and the Definitive Agreements shall terminate
without further liability to either party.


3.     PURCHASE OF EQUIPMENT. Unless the Memorandum of Agreement is terminated
pursuant to Section 2.3 above and subject to satisfaction of the conditions set
forth in this Section 3, Cricket agrees to purchase (or license in the case of
software) from Ericsson Products and Services for mobile and fixed wireless
communications Systems based on CDMA digital wireless communications technology
in markets in the United States, pursuant to the terms and conditions set forth
below. The minimum commitment of Cricket to purchase and Ericsson to sell shall
be $330,000,000 of total value. The purchase obligations of Cricket are subject
to: (i) the existence of Available Markets (as defined below) at any time after
Ericsson is prepared to deliver the first System for commercial operations; (ii)
Ericsson being prepared to deliver the first System for


                                       4
<PAGE>   5
commercial operation within twenty-four (24) months from the Effective Date of
this Memorandum of Agreement and (iii) Ericsson complying with each of the other
terms set forth in this Section 3. If Ericsson fails to meet the milestones
and/or other requirements set forth in this Section 3, Cricket shall have the
option, as its sole and exclusive remedy to terminate this Memorandum of
Agreement and the Definitive Agreements without any further liability to either
party. The terms and conditions of such purchases shall be as follows:

         3.1. TECHNICAL SPECIFICATIONS. The Systems to be purchased by Cricket
and sold by Ericsson shall comply with any specifications agreed to by the
parties in the Definitive Agreements and those additional specifications as
published by Ericsson from time to time thereafter. In addition, in all cases,
the Systems shall meet the "Minimum Equipment Specifications" as set forth on
Exhibit A to this Memorandum of Agreement.

         3.2. DEVELOPMENT PROCESS AND MILESTONES. To demonstrate that the
Systems to be sold by Ericsson will meet the Minimum Equipment Specifications
set forth on Exhibit A, the parties agree that Ericsson shall follow the
"Procedures and Milestones for System Development and Monitoring Program" set
forth on Exhibit B.

         3.3. DEFINITIVE AGREEMENTS. Within thirty (30) days after the Effective
Date, Ericsson and Cricket shall diligently and in good faith negotiate and
execute a System Equipment Purchase Agreement that shall be on the terms and
conditions set forth herein and on those additional terms contained in the Form
of Agreement. In the event of any inconsistency or conflict between the
Memorandum of Agreement and the Form of Agreement, the parties shall revise the
Form of Agreement to be consistent with the terms and concepts contained in this
Memorandum of Agreement. If the parties have not reached agreement on the
Definitive Agreements within thirty (30) days, the parties shall continue
efforts to negotiate the Definitive Agreements, and this Memorandum of Agreement
will continue in full force and effect. The parties shall complete negotiation
of those areas noted as open issues on the Form of Agreement (including but not
limited

                                       5
<PAGE>   6


to missing or incomplete exhibits) and those other areas which require
modification to reflect unique aspects of the Ericsson System and procedures
provided that such modifications are not inconsistent with non-operational
issues provide that no such modification shall require Cricket to accept changes
which materially and adversely impact the cost of acquiring, installing,
maintaining or operating the System, unless such change was expressly
contemplated with regard to an unopen item. Other provisions of the Form of
Agreement shall not be subject to negotiation and the negotiation of open issues
(including prices) will not be inconsistent with terms established herein or in
the Form of Agreement which are not designated as "open."


        3.4. VENDOR FINANCING. Ericsson shall provide to Cricket, vendor
financing in an amount not less than [*] of the purchase price of the System(s)
and Equipment acquired by Cricket from Ericsson on the terms and conditions set
forth in the term sheet attached hereto as Exhibit D, or such more favorable
terms as may be available to Cricket on the date of the Cricket Notice for
shipments on the date that Ericsson intends to first ship Products to Cricket,
if Cricket provides the Cricket Notice as provided above, the terms and
conditions of such financing shall be no less favorable in rates and terms and
conditions to Cricket (and its affiliates) than those terms and conditions
offered by Cricket's other Primary Vendor for comparable financing on the date
Cricket provides Cricket's Notice. "Primary Vendor" means Cricket's or its
affiliates then current primary (i.e., in terms of dollar cost of Equipment then
on order and which has been ordered within the previous three (3) months) vendor
for supplying the Systems. Within sixty (60) days after the Effective Date, the
parties agree to diligently and in good faith negotiate and execute: (i)
definitive form of loan documents, which are substantially similar to those loan
documents of Cricket's other Primary Vendor; and (ii) an intercreditor
agreement. Cricket shall diligently and in good faith attempt to obtain the
Primary Vendor's written approval to the form of an intercreditor agreement to
be used between


[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       6
<PAGE>   7

Ericsson and Primary Vendor. The parties agree to execute documents and
amendments as necessary to accomplish the foregoing.

        3.5. PRICING. The price for the Systems to be purchased by Cricket
pursuant to this Memorandum of Agreement shall not be higher than the pricing
for comparable Systems available to Cricket from the Primary Vendor as of the
date of the Cricket Notice for Systems and Products to be delivered on the date
of first shipment of Ericsson Products to Cricket as established by Cricket
pursuant to the Cricket Notice provided as required by Section 2.2
above. The parties agree to use commercially reasonable efforts to cause the
determination of Ericsson's infrastructure prices versus the infrastructure
prices of the Primary Vendor, to be based on an "apples-to-apples" comparison
(taking into consideration not only the pricing of products and services, the
costs to obtain, install, maintain and operate the system, and the terms and
conditions of any other material consideration proposed to be given or received
by any competing bidder, including the financing terms and conditions and each
of the Competitive Factors (as that term is defined in the Master Agreement).

        3.6. VENDOR PREFERENCE. Provided that: Ericsson (i) has given a
timely Ericsson First Notice; (ii) has satisfied the conditions of Section 3
above; and (iii) has not given an Ericsson Second Notice, Cricket shall purchase
from Ericsson a System for the next Available Market (the "Test Market")
deployed by Cricket or its affiliates after the earlier of: (a) the date
twenty-four (24) months after the Effective Date; or (b) twelve (12) months
after the gives the Ericsson First Notice. "Available Market" means any market
where Cricket or any of its affiliates have acquired a license to build and
operate a System, which is not yet deployed and whether such market currently
exists as of the Effective Date or is acquired thereafter; provided however, it
excludes any Contiguous Markets. A "Contiguous Market" means a market owned by
Cricket or any of its affiliates that is geographically close or proximate to
an existing market where Cricket or any of its affiliates have deployed a
System, and where operating synergies would be

                                       7

<PAGE>   8
gained or capital expenditures would be avoided by deploying additional Systems
identical to those in the existing market (i.e., Salt Lake City, UT would be
considered a Contiguous Market to Provo, UT, since operating efficiencies would
exist). The System deployed in the Test Market will be subject to a "soak"
period, whereby it will be operated for six (6) months after the Substantial
Completion date (the "Test Period") in order to determine whether it is
operating in accordance with the Definitive Agreements and the Specifications.
Provided the System in the Test Market has operated in accordance with the
Specifications and Definitive Agreements during the Test Period, thereafter
Cricket shall purchase from Ericsson any additional Products and Services for
deployment in its remaining Available Markets in accordance with the following:
(i) if as of the expiration of the Test Period the projected cost (as reasonably
set forth in Cricket's business plan) to deploy Products and Services in all of
the remaining Available Markets is equal to or greater than $330,000,000 (less
the price of the Products and Services previously deployed in the Test Market),
then Cricket agrees to purchase a minimum of $330,000,000 (less the price of the
Products and Services previously deployed in the Test Market) of Products and
Services for deployment in such remaining Available Markets; or (ii) if as of
the expiration of the Test Period the projected cost (as reasonably set forth in
Cricket's business plan) to deploy Products and Services in all of the remaining
Available Markets is less than $330,000,000 (less the price of the Products and
Services previously deployed in the Test Market), then Cricket shall purchase
from Ericsson all of its Products and Services requirements for the Remaining
Markets until such time as Cricket has purchased from Ericsson Products and
Services with an aggregate total cost of $330,000,000 (less the price of the
Products and Services previously deployed in the Test Market). Cricket agrees
that it will deploy its Products and Services in good faith in a commercially
reasonable manner and will not arrange the deployment schedule so as to deploy
Products and Services in the Contiguous Markets where the purpose is to delay
the deployment of Ericsson's Products and Services in the Test Market.

4.   EFFECT ON MASTER AGREEMENT REGARDING EQUIPMENT PROCUREMENT. The parties
agree that this Memorandum of Agreement and the purchases described hereunder
satisfies the obligations of the parties under the Master Agreement as it
relates to the Request for Proposal issued by Cricket prior to the Effective
Date. In addition, as further consideration for the purchase commitments of
Cricket as set forth in this Memorandum of Agreement, Ericsson agrees that upon
the earlier of: (i) execution of the Definitive Agreements; or (ii) thirty (30)
days after the Effective Date of this Memorandum of Agreement; (y) the
provisions of Section 2.4.4 of the Master Agreement be and hereby are terminated
and such Section shall be of no further force or effect; and (z) for all future
purchases by Leap and/or Cricket and/or their affiliates under Section 2 of the
Master Agreement, Ericsson's price must be not higher than the Lowest Competing
Infrastructure Bid (defined in the Master Agreement) or there shall be no
obligation to award any procurement to Ericsson (i.e., the parties hereby
eliminate the provisions in Section 2 that require Leap and/or Cricket and/or
their affiliates in certain circumstances to purchase Infrastructure Equipment
(defined in the Master Agreement) from Ericsson if the Ericsson Infrastructure
Prices (defined in the Master Agreement) are within 110% of the Lowest Competing
Infrastructure Bid). Without affecting the immediate enforceability of the
forgoing, the parties agree to negotiate and execute a more formal amendment to
the Master Agreement that will memorialize the foregoing amendments and which
shall be executed concurrently with the Definitive Agreements. Except as set
forth above, the term and provisions of the Master Agreement shall continue in
full force and effect. Notwithstanding the foregoing, pricing and purchase terms
for purchases made under this Memorandum of Agreement and the Definitive
Agreements are not affected by the Master Agreement.

published information as being capable of operating as a functional entity. By
way of example and not limitation, a circuit pack or connecting cable which is
an OEM item, and which forms part of Vendor's CDMA version of the AXE switch
("AXE Switch") would form part of a Core System, whereas a call center system or
voice mail system, though it interfaces with the System, would not be part of a
Core System, since various call center systems or voice mail systems
manufactured by several alternate manufacturers could be utilized by Owner, and
operated functionally independent of the selection of Vendor's Equipment for the
MSC.

carefully studied and compared the Contract with all other information furnished

            2.7 Further Assurances. The Vendor shall execute and deliver all
reasonable further instruments and documents, and will, in good faith, consider
all reasonable requests for further action, including but not limited to
assisting the Owner in filing notices of completion with the appropriate state
and local Governmental Entity, that may be necessary or that the Owner may
reasonably request in order to enable the Owner or the Vendor to complete
performance of the Work or to effectuate the purposes or intent of this
Contract. All such requests shall be addressed pursuant to the Change Order
procedures described below in Section 11.

            2.8 Liens and Other Encumbrances. (a) The Vendor covenants and
agrees, subject to Vendor's receipt from Owner of full payment in respect
thereof, to:

                        (i) protect and keep free all Systems, Expansion and/or
      any and all interests and estates therein acquired from the Vendor, and
      all improvements and materials now or hereafter placed thereon under the
      terms of this Contract, from any and all claims, liens, charges or
      encumbrances of the nature of mechanics, labor or materialmen liens or
      otherwise arising out of or in connection with performance by any
      Subcontractor, including services or furnishing of any materials
      hereunder, and to promptly have any such lien released by bond or
      otherwise; and

                        (ii) give notice of this subsection to each
      Subcontractor before such Subcontractor furnishes any labor or materials
      for any System.

            (b) If any laborers', materialmen's, mechanics', or other similar
lien or claim thereof is filed by any Subcontractor, the Vendor shall cause such
lien to be satisfied or otherwise discharged, or shall file a bond in form and
substance satisfactory to the Owner in lieu thereof within ten (10) Business
Days of the Vendor's receipt of notice of such filing. If any such lien is filed
or otherwise imposed, and the Vendor does not cause such lien to be released and
discharged forthwith, or file a bond in lieu thereof, then, without limiting the
Owner's other available remedies, the Owner has the right, but not the
obligation, to pay all sums necessary to obtain such release and discharge or
otherwise cause the lien to be removed or bonded to the Owner's satisfaction
from funds retained from any payment then due or thereafter to become due to the
Vendor.

            (c) The Owner reserves the right to post or place within any System
notices of non-responsibility or to do any other act required by Applicable Law,
to exempt the Owner from any liability to third parties by reason of any work or
improvements to be performed or furnished hereunder; provided that failure by
the Owner to do so shall not release or discharge the Vendor from any of its
obligations hereunder.

            2.9 Duty To Inform Itself Fully; Waiver of Defense. (a) Each party
shall be deemed to have notice of and to have fully examined and approved the
Specifications, the Exhibits and all other documents referred to herein, and all

regulations and other information in relation to this Contract and/or any
amendments, modifications or supplements thereto at


                                       15

any time on or after the Effective Date and to have fully examined, understood
and satisfied itself as to all information of which it is aware and which is
relevant as to the risks, contingencies and other circumstances which could

            2.11 Pricing.

            2.12. Vendor Preference.

            SECTION 3. PURCHASE ORDERS AND SCHEDULES

            3.1 Purchase Orders. The Owner and any Operating Affiliate may
deliver Purchase Orders to the Vendor at any time and from time to time during
the Contract Term. Such Purchase Orders shall be sent to the Vendor either by
certified mail, electronic transmission or another mutually acceptable manner to
the address specified in Exhibit L of this Contract. All Purchase Orders shall
be governed by the terms and conditions of this Contract, unless otherwise
agreed by the parties in writing. Each Purchase Order shall specify, in
reasonable detail, the Products, Services or other items of Work to be provided
by the Vendor.

            3.2 Delivery under the Contract. The Vendor shall complete the Work
specified in each Purchase Order in accordance with the terms and conditions of
this Contract.

            3.3 Order Acceptance. All Purchase Orders submitted by Owner shall
be deemed to incorporate and be subject to the terms and conditions of this
Contract unless otherwise agreed in writing. All Purchase Orders, including
electronic orders, shall contain the information necessary for Vendor to fulfill
the order. All schedules and requested dates are subject to Vendor's
concurrence, provided that if orders are made within the agreed to lead times
specified in Exhibit L, Vendor shall not withhold its concurrence to the
requested dates. No provision or data on any Purchase Order or contained in any
documents attached to or referenced in any Purchase Order, or any subordinate
document (such as shipping releases), which is inconsistent with the terms of
this Contract shall be binding, except data necessary for Vendor to fill the
order. All such other data and provisions are hereby rejected. Electronic orders
shall be binding on Owner notwithstanding the absence of a signature, provided
that the parties have implemented a mutually acceptable electronic order process
and such orders deemed to be binding have been issued by Owner and accepted by
Vendor in accordance with the process agreed upon by the parties. Order
acceptance provisions, together with delivery schedules and intervals and
forecast requirements are set forth in Exhibit L.

      While it is Vendor's objective to provide Owner with an acknowledgment of
each Purchase Order received, Owner shall advise Vendor to the extent that Owner
becomes


                                       16
<PAGE>   31
aware of any missing or late notifications to ensure that the Purchase Order has
not been lost.

      Changes made by Owner to an accepted Purchase Order shall be treated as a
separate order unless the parties expressly agree otherwise. If any such change
affects Vendor's ability to meet its obligations under the original Purchase
Order, any price, shipment date, or completion date quoted by Vendor with
respect to such original order is subject to change and shall be addressed
pursuant to the Change Order provisions below in Section 11.

            3.4 Forecasts. Owner shall provide to Vendor regular forecasts of
Owner's annual Product and Services needs. If the quantities ordered are more
than [*] greater than forecast quantities, Vendor shall be permitted a
reasonable extension of time to fulfill such orders and achieve the Milestones
required of Vendor hereunder.

            3.5 Deployment Plans and Milestones. The deployment plans and
intervals, together with the key milestones, order lead times, in respect of
each System, are set forth in Exhibit L.

            3.6 Inventory Control and Bar-coding. Vendor shall, at no additional
charge, pack and mark shipping containers in accordance with its standard
practices for domestic shipments. Where in order to meet Owner's requests,
Vendor packs and/or is required to mark shipping cartons in accordance with
Owner's specifications, Vendor shall invoice Owner additional charges for such
packing and/or marking. Vendor shall: (i) enclose a packing memorandum with each
shipment and, if the shipment contains more than one package, identify the
package containing the memorandum; and (ii) mark Products as applicable for
identification in accordance with Vendor's marking specifications (for example,
model/serial number and month, year of manufacture).

            SECTION 4. SUBCONTRACTORS

            4.1 Subcontractors. The Vendor may subcontract any portion of its
obligations under this Contract, but no such subcontract shall relieve Vendor
from primary responsibility and liability for the performance of Vendor's
covenants and obligations under this Contract. Regardless of whether or not the
Vendor obtains approval from the Owner or a Subcontractor or whether the Vendor
uses a Subcontractor recommended by the Owner, use by the Vendor of a
Subcontractor shall not, under any circumstances: (i) give rise to any claim by
the Vendor against the Owner if such Subcontractor breaches its subcontract or
contract with the Vendor; (ii) give rise to any claim by such Subcontractor
against the Owner; (iii) create any contractual obligation by the Owner to the
Subcontractor; (iv) give rise to a waiver by the Owner of its rights to reject
any Defects or Deficiencies or Defective Work; or (v) in any way release the
Vendor from being solely responsible to the Owner for the Work to be performed
under this Contract.

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

<PAGE>   32
            4.2 Vendor's Liability. The Vendor is responsible for all of its
obligations under this Contract, including the Work, regardless of whether a
subcontract or supply agreement is made or whether the Vendor relies upon any
Subcontractor to any extent. The Vendor's use of Subcontractors for any of the
Work shall in no way increase the Vendor's rights or diminish the Vendor's
liabilities to the Owner with respect to this Contract, and in all events,
except as otherwise expressly provided for herein, the Vendor's rights and
liabilities hereunder with respect to the Owner shall be as though the Vendor
had itself performed such Work. The Vendor shall be liable for any delays caused
by any Subcontractor as if such delays were caused by the Vendor.

            4.3 No Effect of Inconsistent Terms in Subcontracts. The terms of
this Contract shall in all events be binding upon the Vendor regardless of and
without regard to the existence of any inconsistent terms in any agreement
between the Vendor and any Subcontractor whether or not and without regard to
the fact that the Owner may have directly and/or indirectly had notice of any
such inconsistent term.

            4.4 Assignability of Subcontracts to Owner. Vendor shall use
reasonable efforts to have each agreement between the Vendor and a Subcontractor
contain a provision stating that, in the event that the Vendor is terminated for
cause, convenience, abandonment of this Contract or otherwise then: (i) each
Subcontractor shall continue its portion of the Work as may be requested by the
Owner; and (ii) such agreement permits assignment thereof without penalty to the
Owner and, in order to create security interests, to third parties designated by
Owner, in either case at the option of the Owner and for the same price and
under the same terms and conditions as originally specified in such
Subcontractor's agreement with the Vendor.

            4.5 Removal of Subcontractor or Subcontractor's Personnel. The Owner
has the right at any time to request removal of a Subcontractor and/or any of a
Subcontractor's personnel from Work on the System upon reasonable grounds and
reasonable prior notice to Vendor. Such request (a "Request for Removal") shall
be in writing and shall specify the Owner's reasoning therefor. The Vendor
promptly shall issue a written response to any such Request for Removal,
specifying the reasoning for its disagreement or agreement, as the case may be,
with the reasoning contained in the Request for Removal. If the parties fail to
agree, this matter shall be handled in accordance with the dispute resolution
procedures in Section 23. The exercise of such right by the Owner shall have no
effect on the provisions of subsections 4.1 and 4.2.

            4.6 Subcontractor Insurance. The Vendor shall require its
Subcontractors to obtain, maintain and keep in force, during the time they are
engaged in providing Products and Services hereunder, insurance coverage of the
types and levels customary in the industry (provided that the maintenance of any
such Subcontractor insurance shall not relieve the Vendor of its other
obligations pursuant to this Contract). The Vendor shall, upon the Owner's
request, furnish the Owner with evidence of such insurance in form and substance
reasonably satisfactory to the Owner.


                                       18
<PAGE>   33
            4.7 Review and Approval not Relief of Vendor Liability. No
inspection, review or approval by the Owner permitted under this Contract of any
portion of the Work shall relieve the Vendor of any duties, liabilities or
obligations under this Contract, but nothing contained in this subsection shall
be deemed a bar of any waiver given by the Owner to the Vendor pursuant to and
in accordance with the terms of this Contract.

            4.8 Vendor Warranties. Except as otherwise expressly provided in
Section 18, the warranties of the Vendor pursuant to Section 18 shall be deemed
to apply to all Work performed by any Subcontractor as though the Vendor had
itself performed such Work and to all Products supplied by any third-party
vendor or other subcontractor as though the Vendor itself had supplied such
Products. Except as otherwise specifically provided in Section 18, the parties
agree that such warranties shall not be enforceable merely on a "pass-through"
basis but that Owner may, but shall not be obligated to, enforce such warranties
of any Subcontractor to the extent that the Owner determines that the Vendor is
not paying and/or performing its warranties; provided that any such election by
the Owner shall not relieve the Vendor from any obligations or liability with
respect to any such warranty.

            4.9 Payment of Subcontractors. The Vendor shall make all payments it
is contractually required to make to all Subcontractors (except in the case of
legitimate disputes between the Vendor and any such Subcontractor arising out of
the agreement between the Vendor and such Subcontractor) in accordance with the
respective agreements between the Vendor and its Subcontractors such that no
Subcontractor shall be in a position to enforce any liens and/or other rights
against the Owner, the System, any Products or any part thereof.

            4.10 Copies. Subject to any confidentiality obligations insisted
upon by third party providers, including Subcontractors, Vendor will use its
good faith, reasonable efforts to provide Owner with any and all relevant
agreements, understandings, subcontracts and other documents pertaining to the
provision of Products or Services by a Subcontractor which Owner may reasonably
require in order for it to be provided with the information necessary to
exercise any of its rights under this Contract.

            4.11 Benefit of Subcontracts. In addition to anything else provided
for in this Contract, the Owner shall be entitled to the following benefits and
rights of the Vendor under its contracts with any applicable third-party vendors
or other Subcontractors: all rights to conduct in-house tests, to receive notice
of upgrades and enhancements and to purchase spare parts; provided however, that
the Vendor shall maintain sole responsibility for all obligations and other
duties under all such contracts.

Contract, provided, however, that the Owner shall not be liable for and shall
not pay or reimburse Vendor for any Taxes on or measured by the income or

      Certificate of Substantial Completion is not issued within five (5)
      Business Days after the Guaranteed Substantial Completion Date because of
      a delay in reaching Substantial Completion solely attributable to the

      commitments in a timely manner, such amount shall be invoiced on the fifth
      (5th) Business Day following Substantial Completion; and

[*] Certain material (indicated by an asterisk) has been omitted from this

thereafter as practical but in no event more frequently than monthly, provided

respect of the System for which such Services are rendered; provided that in the
event that a Certificate of Substantial Completion is not issued within five (5)
Business Days after the Guaranteed Substantial Completion Date because of a
delay in reaching Substantial Completion solely attributable to the failure or
lack of performance of Owner to satisfy its obligations and commitments in a
timely manner, such amount shall be invoiced on the fifth (5th) Business Day
following Substantial Completion.

            (c) Optional Software Features and Spares. The purchase price for
the initial Optional Software Features and Spares shall be invoiced after the

which such initial Optional Software Features and Spares are furnished; provided
that in the event that a Certificate of Substantial Completion is not issued
within five (5) Business Bays after the Guaranteed Substantial Completion Date
because of a delay in reaching Substantial Completion attributable solely to the
failure or lack of performance of Owner to satisfy its obligations and
commitments in a timely manner, such amount shall be invoiced on the fifth (5th)

            (d) Expansions. [To be negotiated.]

      the Vendor with respect to Products for which Vendor provides no
      installation Services pursuant to an Expansion shall be invoiced upon
      delivery of such Products.

            (e) Payment of Invoices. Owner shall pay the invoiced amounts, less
any disputed amounts, within ten (10) days from the date of transmission of
Vendor's invoice. Delinquent payments are subject to a late payment charge after

of this Contract.

            5.6 In Revenue Payments. At any time during a period of delay the
Owner may, in its sole discretion, decide to place a System which is subject to
such delay into In Revenue Service. Such placement into In Revenue Service shall
constitute Substantial Completion only for purposes of the payment obligations
above, but shall not in any way relieve the Vendor of any of its obligations
under this Contract, including without limitation achieving a Guaranteed
Substantial Completion Date nor shall such In Revenue Service trigger the
commencement of the Initial Period.

            5.7 Currency and Place of Payment. Payments under this Contract

Owner, Owner shall pay all amounts due Vendor hereunder using Electronic Funds

transportation arrangements out of the ordinary course having regard to normal
industry standards and practices (such as non-standard crane requirements,
helicopter transportation requirements to a remote setting, etc.), Vendor shall
arrange, subject to Owner's prior approval, for such exceptional transportation
requirements from local staging facilities or warehouse locations to the unusual
Site. Vendor shall notify Owner that it believes, in good faith, that

and Vendor will consult with Owner on an approved course of action to complete
delivery. Owner shall be responsible for all costs with respect to such
exceptional transportation requirements in excess of transportation costs
applicable to a standard Site.

build each of the Systems so as to cause no unauthorized interference with or
obstruction to lands and thoroughfares or rights of way on or near which the
installation work may be performed. The Vendor shall exercise every reasonable
safeguard to avoid damage to existing facilities, and if repairs or new
construction are required in order to replace facilities damaged by the Vendor
due to its carelessness, negligence or willful misconduct, such repairs or new
construction shall be at the Vendor's sole cost and expense. Vendor understands
that many of the Sites may be co-located with other RF transmission facilities
and Vendor shall take all necessary precautions and safety measures to ensure
the safety of all of Vendor's and Subcontractors' personnel at such Sites. The
Owner shall use its reasonable best efforts to ensure that no other third
parties employed or engaged by the Owner hinder or delay the Vendor in the
performance of its installation obligations hereunder.

            Vendor represents and warrants that all Products furnished hereunder
shall comply, to the extent required, with the requirements of Part 24 of the
Federal Communication Commission's Rules and Regulations (the "FCC Rules")
pertaining to personal communications services in effect upon delivery of such
Product. In addition, Vendor represents and warrants that a Product furnished
hereunder shall comply, to the extent required, with the requirements of Subpart
J of Part 15 of the FCC Rules in effect upon delivery of such Product, including
those sections concerning the labeling of such Product and the suppression of
radio frequency and electromagnetic radiation to specified levels. Vendor makes
no undertaking with respect to harmful interference caused by (i) unauthorized
installation, repair, modification or change or Products not furnished by
Vendor; (ii) Products being subject to misuse, neglect, accident or abuse by
other than Vendor; (iii) Products being used in a manner not in accordance with
operating instructions or in a suitable installation environment or operations
of other equipment in the frequency ranges reserved for Owner within the
applicable licensed area. Vendor assumes no


                                       23
<PAGE>   38
responsibility under this clause for items not specified or supplied by Vendor.
The foregoing warranties are collectively referred to as the "Compliance
Warranty".

            Vendor shall, when appropriate, have reasonable access to Owner's
premises during normal business hours and at such other times as may be agreed
upon by the parties in order to enable Vendor to perform its obligations under
this Contract. Vendor shall coordinate such access with Owner's designated
representative prior to visiting such premises. Vendor agrees to instruct its
employees to comply with all site rules while on Owner's premises. The employees
and agents of Vendor shall, while on the Owner's premises, comply with all site
rules and guidelines including but not limited to where required by government
regulations, submission of satisfactory clearance from U.S. Department of
Defense and other governmental authorities concerned. Neither party shall
require waivers or releases of any personal rights from representatives of the
other in connection with visits to its premises, and no such releases or waivers
shall be pleaded by either party in any action or proceeding.

            For purposes of this Section, all references to "Owner's premises"
and other similar references shall be deemed to refer to any location where a
Site is to be located, which may include land or buildings owned or leased by
Owner. To the extent that Owner does not own the premises, Vendor's obligations
to adhere to site rules and guidelines shall include, without limitation, those
rules and guidelines required by the owner, landlord or property manager having
care and control of such premises, which Owner has provided to Vendor in advance

            SECTION 11. CHANGE ORDERS AND SCHEDULING

            11.1 Change Orders. The Owner has the right to request expansions,
other revisions and/or modifications to any Purchase Order or to the Work
("Changes"), including but not limited to the Specifications, the manner of
performance of the Work or the timing of the completion of the Work. All Changes
shall be subject to the prior written consent of the Vendor. All Changes shall
be documented in a written order ("Change Order") which shall be executed by the
Owner and the Vendor and shall contain any adjustments to pricing, Milestone or
other aspect of the Work as mutually agreed by the parties. The Vendor shall
promptly notify the Owner of any such requested Changes which may materially
affect the operation and/or maintenance of any System or any part thereof. In
the event that the parties cannot agree on a Change Order within fifteen (15)
days of submission of a Change Order by the Owner to the Vendor, the matter
shall then be referred to dispute resolution pursuant to Section 23. Nothing
contained in this subsection is intended to limit the Vendor's right, from time
to time, to make suggestions for modifications to the Work or the
Specifications, provided that in any such event the Owner, in its sole and
absolute discretion pursuant to the terms of this Contract may refuse to make
any such modification or otherwise agree to issue a Change Order incorporating
any such Vendor suggestion.

            11.2 Cancellation. Owner may at any time to cancel, in whole or in

    Commission.

                                       27
<PAGE>   42
event of such cancellation, the Owner shall pay to the Vendor cancellation
charges in accordance with the Exhibits.

            SECTION 12. DISCONTINUED PRODUCTS AND CONTINUING PRODUCT SUPPORT

            12.1 Notice of Discontinuation. For a period of [*] for the
AXE switch and [*] for all other Products furnished hereunder after the
Effective Date, but in no event less than [*] after the date of shipment,
the Vendor agrees to provide the Owner, or its affiliates as the case may be,
not less than one (1) year notice before the Vendor discontinues a Product
("Discontinued Products") furnished under this Contract. With respect to
Products manufactured by a third party vendor, the notice period may vary. Where
the Vendor offers a product for sale that is equivalent in Form, Fit and
Function in accordance with and pursuant to the Specifications, the notification
period may vary but in no event shall be less than sixty (60) days. In the event
of the foregoing, the Vendor shall continue to furnish Products fully compatible
with the relevant System Elements within the System at such time during the
appropriate [*] and [*] periods referenced above; provided that nothing
herein shall bar the Vendor from discontinuing individual items of Products as
provided in and pursuant to this subsection. In the event that Vendor
discontinues a Product, Vendor will meet with Owner and use reasonable, good
faith efforts to develop a mutually acceptable transition plan that takes into
account the Owner's existing investment in the item scheduled for
discontinuance.

            In addition to repairs provided for under any applicable Warranty,
Vendor shall offer repair Services and repair parts in accordance with Vendor's
repair and repair parts practices and terms and conditions then in effect, for
Vendor-manufactured Equipment furnished pursuant to this Contract. Such repair
Services and repair parts shall be available while Vendor is manufacturing or
stocking such Products or repair parts, but in no event less than [*] for
the AXE switch and [*] for all other Products after such Product's discontinued
availability effective date. Vendor may use either the same or functionally
equivalent products or parts which are new, remanufactured, reconditioned or
refurbished in the furnishing of repairs or replacements under this Contract.

            If during the agreed-to support period following the issuance of
notice of discontinuance, Vendor fails to provide repair parts and or repair
Services and a functionally equivalent replacement has not been designated,
Vendor shall so advise Owner, to allow Owner to plan appropriately, and if
Vendor is unable to identify another source of supply for such repair parts or
services, Vendor shall, in addition to any other right or remedy available to
Owner at law or in equity, provide Owner, at no additional charge to Owner, upon
request, with non-exclusive licenses for Product manufacturing to the extent
Vendor can grant such licenses, so that Owner will have sufficient information,
ability and rights to have such Discontinued Products manufactured, or obtain
such repair Service or repair parts from other sources. Such license shall
include appropriate non-disclosure and confidentiality covenants.

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

            12.2 Discontinuation During Warranty Period. If Vendor discontinues
the availability of a Product during that Product's Warranty Period and Owner is
required to purchase a replacement Product to replace the Discontinued Product
in order to maintain the same functionality of the Discontinued Product in a
System, Vendor agrees to grant Owner an additional [*] discount to be applied
against the net price of all Products required to be purchased by Owner as
replacements for such Discontinued Product, which additional discount shall be
applied after the determination of the lowest price available to Owner pursuant
to this Contract.

            SECTION 13. SOFTWARE; CONFIDENTIAL INFORMATION

            13.1 RTU License. Upon delivery of the Software, but subject to
payment of the license fees specified in Exhibit B-5, the Owner is hereby
granted a personal, non-exclusive, fully paid-up, multi-site (capability to move
Software from site to site on prior notice to Vendor) right to use license for
the Software ("RTU License"), to operate the specific Equipment, processor or
product line for which the licenses to use the Software are initially granted,
or temporarily on any comparable replacement if any such Equipment, processor or
product line becomes inoperative. Owner shall use such Software only for its own
internal business operation. The RTU License grants Owner no right to, and Owner
will not, sublicense such Software or modify, decompile, or disassemble Software
furnished as object code to generate corresponding source code provided in each
of the Systems. Except as provided below, no license is granted to Owner to use
the Software outside of the United States.

            In the event that Owner wishes to use the Software on associated
equipment outside of the United States or to transfer Software to an affiliate
or third party transferee located outside the United States, Vendor shall not
unreasonably withhold its consent to such use or transfer, provided that Vendor
or the transferee, as the case may be, enters into an appropriate license
agreement with an affiliate of Vendor carrying on business in the territory in
which the Software is to be located, on terms substantially similar to the RTU
License terms set forth herein, provided, however, that Owner acknowledges and
agrees that support and maintenance obligations set forth herein are only
applicable for Software resident on Equipment located within the United States.
Support and maintenance Services offered by Vendor's affiliates differs in
various different territories, and will be subject to the local practices
maintained in such territory.

            13.2 Owner's Obligations. The Owner agrees that the Software,
whether or not modified, and all copies thereof made by Owner, shall be treated
as proprietary to the Vendor, its Subcontractors or its suppliers, as
appropriate and the Owner shall:

            (a) Utilize the Software solely in conjunction with a System;
provided that the Vendor acknowledges that the Software shall be integrated
across interfaces with systems, equipment and software provided by other
suppliers and customers;

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       29
<PAGE>   44
            (b) Ensure that all copies of the Software shall, upon any
reproduction by the Owner authorized by the Vendor and whether or not in the
same form or format as such Software, contain the same proprietary,
confidentiality and copyright notices or legends which appear on the Software
provided pursuant hereto; and

            (c) Hold secret and not disclose the Software to any person, except
to (i) such of its employees, contractors, agents or affiliates that are
involved in the operation or management of a System and need to have access
thereto to fulfill their duties in such capacity, or (ii) other Persons who need
to use such Software to permit integration of a System with systems and software
of other suppliers and customers; provided that such persons agree, or are
otherwise obligated, to hold secret and not disclose the Software to the same
extent as if they were subject to this Contract, and provided further that if
any such Person is a competitor of Vendor involved in the manufacture of
communications equipment, software or related services, Vendor must approve such
use on a case-by-case basis on commercially reasonable terms and such use shall
be subject to an appropriate non-disclosure agreement.

            (d) When and if the Owner determines that it no longer needs the
Software or if the Owner's license is canceled or terminated pursuant to the
terms of this Contract, return all copies of such Software to the Vendor or
follow reasonable written disposition instructions provided by the Vendor. If
the Vendor authorizes disposition by erasure or destruction, the Owner shall
remove from the medium on which Software resides all electronic evidence of the
Software, both original and derived, in such manner that prevents subsequent
recovery of such original or derived Software.

            (e) Owner shall not copy Software embodied in firmware and unless
otherwise specifically provided in this Contract, Owner is not granted any right
to modify Software furnished by Vendor under this Contract.

            13.3 Backwards Compatibility. The Vendor represents and warrants
(the "Software Backwards Compatibility Warranty") that each Software Maintenance
Release, Software Upgrade and Software Enhancement will be Backwards Compatible.
[***] Notwithstanding the foregoing, the Software Backwards Compatibility
Warranty does not apply to Products developed AXE in accordance with standards
not yet finalized as of the date hereof.

            13.4 Transfer and Relocation. (a) In the event the Owner or any
successor to the Owner's title in the Products: (i) elects to transfer a Product
to a third party, and where such Product shall remain in place and used for
substantially the same purpose as used by the Owner and where such third party
resides in the United States and is not a direct competitor of the Vendor
involved in the manufacture of communications equipment, software or related
services; or (ii) elects to transfer Products to an affiliate, the Owner may

    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       30
<PAGE>   45
transfer its RTU License for the Software furnished under this Contract for use
with such Product, without the payment of any additional Software right-to-use
fees by the transferee provided that Annual Maintenance Fees shall continue to
be calculated on the same basis. For example, if the RTU License for the
Software contains usage or per subscriber limits, or the processor to be used by
transferee requires additional memory or hard disk space additional payments or
purchases may be required. The following conditions shall apply to transfers and
relocations pursuant to this subsection 13.4:

            (A)   The right to use such Software may be transferred only
                  together with the Products with which the Owner has a right to
                  use such Software, and such right to use the Software shall
                  continue to be limited to use with such Products;

            (B)   Before any such Software is transferred, the Owner shall
                  notify the Vendor of such transfer and the transferee shall
                  have agreed in writing (a copy of which shall be provided to
                  the Vendor) to keep the Software in confidence and to
                  corresponding conditions respecting possession and use of
                  Software as those imposed on the Owner in this Contract; and

            (C)   The transferee shall have the same right to Software warranty
                  and Software maintenance for such Software as the transferor,
                  provided the transferee continues to pay the fees, including
                  recurring fees, if any, associated with such Software warranty
                  or maintenance pursuant to this Contract.

            (b) Except as otherwise provided in this Contract, the Owner or any
successor to the Owner's title in the Products shall have no right to transfer
Software furnished by the Vendor under this Contract without the consent of the
Vendor, which consent shall not be unreasonably withheld. If the Owner or such
successor elects to transfer a Product purchased under this Contract for which
it does not under this Contract have the right to transfer related Software, the
Vendor agrees that upon written request of the transferee of such Product, or of
the Owner or such successor, the Vendor shall not without reasonable cause fail
to grant to the transferee a license to use such Software with the Products,
whether to be located within the United States or elsewhere, upon payment of a
relicensing fee to the Vendor on commercially reasonable terms acceptable to
Vendor.

            13.5 Termination and Survival. The rights and obligations of the
Owner under the RTU License shall survive the termination of this Contract,
regardless of the cause of termination provided Owner has met its material
obligations hereunder and has rendered all payments in accordance with this
Contract. In the event that Owner persistently and materially breaches its
confidentiality obligations hereunder with respect to the Software
notwithstanding the fact that Vendor will have provided Owner with prior written
notice describing the alleged material breaches and will have given Owner a
reasonable time, and in no event less than thirty (30) days, to cure any such
breaches, Vendor may terminate Owner's RTU License. In the event that Owner
fails to pay the Annual Release


                                       31
<PAGE>   46
Maintenance Fees (other than with respect to any periods for which no payment
for Annual Release Maintenance Fees are due pursuant to this Contract), Vendor
may terminate Owner's right to use the Software to which such fees apply. In no
event other than as set forth in this subsection 13.5 may Vendor terminate
Owner's right to use the Software. Notwithstanding any other provision of this
Contract, if there is a dispute, pending final resolution of such dispute, all
of Owner's rights under this Contract shall continue in full force and effect,
and Vendor will not terminate the RTU License, and so long as Owner continues to
pay Vendor applicable Annual Maintenance Release Fees, Vendor will not
terminate, suspend, interrupt or delay maintenance and support of the Software.

            13.6 Access to Source Codes. The Vendor represents and warrants that
as of the date hereof, Vendor has not established a Source Code escrow for any
of its existing customers. In the event that Vendor establishes a Source Code
escrow in the future which applies to any of the Software furnished to Owner
hereunder, Vendor shall add Owner as a beneficiary of such Source Code escrow,
and Owner shall be entitled to receive a copy of the escrowed Source Code in the
event of the occurrence of any of the events set out below. In addition to the
foregoing, the Vendor shall immediately deliver and hereby grants the Owner a
right to access the Source Code and to modify the Software (the "RTM License")
for the maintenance, enhancement and support of those Products purchased from
the Vendor and owned or operated by the Owner under the following circumstances,
provided that any such released Source Code shall be subject to the
confidentiality provisions set forth in this Contract:

                        (i) if the Vendor becomes insolvent, makes a general
      assignment for the benefit of creditors, files a voluntary petition in
      bankruptcy or an involuntary petition in bankruptcy is filed against the
      Vendor which is not dismissed within sixty (60) days, or suffers or
      permits the appointment of a receiver for its business, or its assets
      become subject to any proceeding under a bankruptcy or insolvency law,
      domestic or foreign, or has liquidated its business, or the Vendor, or a
      business unit of the Vendor that is responsible for maintenance of the
      Software, ceases doing business without providing for a successor, and the
      Owner has reasonable cause to believe that any such event shall cause the
      Vendor to be unable to meet its Warranty service or support requirements
      hereunder; or

                        (ii) if the Vendor ceases to maintain or support a
      previously supported version of the Software and Owner cannot obtain, with
      Vendor's assistance (for example, by providing a third party with Source
      Code or by any other appropriate method) the same support services the
      Vendor is required to provide under this Contract from another entity
      (either working with or independently from Vendor) at a price that is
      equal to or less than the prices for such support as provided herein, or
      there is a persistent and material failure by Vendor to provide the
      Warranty service or support it is required to provide pursuant to the
      terms of this Contract.

            13.7 Ownership of Intellectual Property. The Vendor shall own all
forms of intellectual property rights (including, but not limited to, patent,
trade secret, copyright and


                                       32
<PAGE>   47
mask rights) pertaining to the Software, and shall have the right to file for or
otherwise secure and protect such rights. The foregoing notwithstanding, the
parties understand and agree that from time to time the Owner may devise,
develop or otherwise create ideas or other concepts for services or new products
which are patentable or otherwise capable of receiving protection from
duplication. In such event, the Owner shall have the right to apply for a patent
in accordance with applicable law, provided, however, that notwithstanding this
subsection, the Vendor does not hereby relinquish or release any of its
intellectual property rights.

Specifications and the Exhibits and restore all pre-existing functionality and
features as well as provide any new features and functionality provided by any
of the foregoing modifications, in each case without any charge to the Owner
(other than payment of the applicable fees pursuant to the terms of this
Contract). Notwithstanding anything contained herein in this subsection to the
contrary, Owner shall be responsible for the cost of any additional Equipment
required to accommodate additional capacity, memory or processing requirements
necessitated by any new Software feature or Optional Software Feature which
Owner elects to use (provided such use by Owner is optional without losing the
benefit of the Software Maintenance Release or Software Upgrade) which are
contained in any such Software Upgrade, Software Enhancement or Software
Combined Release; provided, however, that Owner shall not be required to pay for
any additional Equipment required to accommodate additional capacity, memory or
processing requirements necessitated by implementation of a required Software
Maintenance Release, whether or not such Software Maintenance Release is issued
as a stand-alone release, or is contained within a Software Upgrade, Software
Enhancement or Software Combined Release.

            14.2 Equipment.

            14.2.1 Equipment Upgrades. (a) Equipment Upgrades will be provided
to the Owner by the Vendor at no charge to the Owner as provided in subsection
14.2.1(b) below. Equipment Enhancements must be provided to the Owner by the
Vendor, if requested by the Owner, and the Owner is obligated to make payment
therefor in an amount that is specified on the B Exhibits. If the Vendor at any
time issues an Equipment Upgrade which is combined with any Equipment
Enhancement (collectively, the "Equipment Combined Release") to such Equipment,
the Equipment Combined Release will be provided at no charge to the Owner unless
and until the Owner uses any of the Equipment Enhancements included within the
Equipment Combined Release, provided such use by Owner of such Equipment is
optional without losing the benefit of the Equipment Upgrade.

            (b) (i) After a Product has been shipped to the Owner, if the Vendor
issues an Equipment Upgrade or Equipment Enhancement, or where a modification to
correct an error in field documentation is to be introduced, the Vendor will
promptly notify the Owner of such change through the Vendor's design change
management system or another Vendor notification procedure. Each change
notification, whether or not it bears a restrictive legend, will be subject to
the confidentiality obligations provided in subsection 26.18, except that such
information may be reproduced by the Owner for the Owner's use as required
within the System. If the Vendor has engineered, furnished, and installed a
Product which is subject to an Equipment Upgrade, the Vendor will implement such
change, at its sole cost and expense, if it is announced within [*] for the AXE
switch and [*] for all other Products from the date of shipment of that Product,
and subject to the reasonable review and acceptance of the Owner at such times
as the Owner reasonably determines that it needs to review such Vendor decision,
by either (A) modifying the Product at the Owner's site; (B) modifying the
Product which the Owner has returned to the Vendor in accordance with the
Vendor's reasonable instructions pursuant to and in

[*]  Certain material (indicated by an asterisk) has been omitted from this
     document pursuant to a request for confidential treatment. The omitted
     material has been filed separately with the Securities and Exchange
     Commission.

                                       34
<PAGE>   49
accordance with the terms of this Contract; or (C) replacing the Product
requiring the change with a replacement Product for which such change has
already been implemented. If the Vendor has not engineered the original Product
application and accordingly office records are not available to the Vendor, the
Vendor will provide the generic change information and associated parts for the
Owner's use in implementing such change.

            (ii) In any of the instances described in clause (i) above, if the
Vendor and the Owner agree that a Product or part thereof subject to such change
is readily returnable, without incurring any significant time or expense, the
Owner, at its expense, will remove and return such Product or part to the
Vendor's designated facility within the United States and the Vendor, at its
sole expense, will implement such change (or replace it with a Product or part
for which such change has already been implemented) at its facility and return
such changed (or replacement) Product or part at its sole cost and expense to
the Owner's designated location within the United States. Any such
reinstallation of Products which were readily returnable will be performed by
the Owner at its sole expense, provided such reinstallation can be done by Owner
without incurring any significant time or expense. In all other circumstances,
Vendor shall provide such removal, repair and reinstallation Services at its
sole cost and expense.

            (iii) If the Owner does not make or permit the Vendor to make an
Equipment Upgrade as stated above within the appropriate [*] or [*] period from
the date of change notification or such other period as the Vendor may agree,
subsequent changes, repairs or replacements affected by the failure to make such
change may, at the Vendor's option, be invoiced to the Owner whether or not such
subsequent change, repair or replacement is covered under the warranty provided
in this Contract for such Product. If requested by the Owner, Equipment Upgrades
announced more than the appropriate [*] or [*] period from the date of shipment
will be implemented at the Owner's expense.

            (iv) If the Vendor issues an Equipment Enhancement after a Product
has been shipped to the Owner, the Vendor will promptly notify the Owner of such
change if it is being offered to any of the Vendor's customers. Except as
otherwise set forth above in subsection 14.2(b), when an Equipment Enhancement
is requested by the Owner, the pricing set for such Equipment Enhancements will
be at the Vendor's standard charges subject to the applicable discounts set
forth in the B Exhibits.

            (v) All change notifications for Equipment Upgrades and Equipment
Enhancements provided by the Vendor to the Owner pursuant to the terms of this
Contract must contain the following information: (A) a detailed description of
the change; (B) the reason for the change; (C) the effective date of the change;
and (D) the implementation schedule for such change, if appropriate.

            14.2.2 Notice. The Vendor shall give, or shall cause to be given to,
the Owner not less than ninety (90) days prior written notice of the
introduction of any Equipment Enhancement or any Equipment Combined Release. In
addition, in each February and August of each year during the Term of this
Contract, the Vendor shall

    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       35
<PAGE>   50
provide the Owner with a forecast of future Equipment Enhancements to the
Equipment or Equipment Combined Releases then currently being developed by or on
behalf of the Vendor.

            14.2.3 Installation, Testing and Acceptance The Installation and
testing of the Equipment by the Vendor and the acceptance thereof by the Owner
shall be performed in accordance with the Exhibits and pursuant to the
Milestones contained in the Exhibits.

            14.2.4 Equipment Fixes. In the event that any Equipment Upgrade or
Equipment Enhancement, directly or indirectly, supplied by the Vendor during the
appropriate [*] or [*] period following the Effective Date or during [*] period
following the date of shipment of such Equipment Upgrade or Equipment
Enhancement, has the effect of preventing any System or any part thereof from
satisfying, or performing in accordance with, the Specifications or otherwise
adversely affects the functionality, interoperability or features of any System,
or any part thereof then the Vendor shall without any charge to the Owner
promptly retrofit or take such other corrective action as may be necessary to
assure that any System or any such affected part, as modified to include each
such Equipment Upgrade and Equipment Enhancement, shall satisfy, and perform in
accordance with, the Specifications and restore all pre-existing functionality
and features as well as provide any features and functionality provided by any
of the foregoing modifications.

            14.2.5 Equipment Backwards Compatibility Warranty. The Vendor
represents and warrants (the "Equipment Backwards Compatibility Warranty") that
each New Equipment Release will be Backwards Compatible, provided that it is
implemented within the specified time provided with each New Equipment Release.
[***] Notwithstanding the foregoing, the Equipment Backwards Compatibility
Warranty does not apply to Products developed beyond AXE standards not yet
finalized as of the date hereof.

            14.3 Notice of Developments.

            14.3.1 Vendor Developments. The Vendor shall provide the Owner, or
cause to be provided to the Owner, through the Owner's chief executive officer,
with reasonable written notice of any Product developments, innovations and/or
technological advances (collectively "Vendor Developments") relevant to the
System simultaneous to giving such notice to any other customer or otherwise
making any such Vendor Development public; provided that the Vendor shall not be
obligated to provide the Owner such notice before any other customer if doing so
would breach any contractual obligation to any other customer, provided further
that any such notice need not include any information originated by another
customer of Vendor which is proprietary to such other

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       36
<PAGE>   51
customer of Vendor. For the purposes of this subsection the term "Vendor"
includes the Vendor and its affiliates and subsidiaries.

            14.3.2 Participation in Testing. The Owner has the right, but not
the obligation, to witness and/or participate in any initial testing; provided
that any such initial testing of Vendor Developments shall be subject to: (i)
scheduling as reasonably determined by the Vendor; (ii) the qualification that
the Owner's System meets the technical requirements for the testing of such
Vendor Development as reasonably determined by the Vendor (or otherwise that the
Owner is willing to update such System to meet such requirements); (iii) the
Owner's acknowledgment that it shall be able to provide the resources necessary
to implement the initial testing for such Vendor Development; and (iv) the Owner
and the Vendor executing a verification office testing agreement that identifies
the scope, terms, pricing, responsibilities and schedule related to the initial
testing of such Vendor Development. The Vendor shall provide the Owner at least
thirty (30) days prior written notice of its intent to test any such Vendor
Development and upon the Owner's written request the Vendor shall allow the
Owner to participate in such testing upon terms and in a testing environment
reasonably acceptable to the parties at such time. Such rights shall not apply
to a Vendor Development originated by another customer of Vendor which includes
information which is proprietary to such other customer.

            14.3.3 Quarterly Notices. Vendor shall make reasonable efforts to
collect and distribute on a quarterly basis a list of new Software bugs,
problems, fixes, etc., provided that Vendor shall not be required to distribute
confidential information of any other customer.

            SECTION 15. INTELLECTUAL PROPERTY

            15.1 Intellectual Property. Neither Owner nor Vendor shall publish
or use any advertising, sales promotion, press releases or publicity matters
relating to this Contract without the prior written approval of the other, in
accordance with subsection 26.13.

            15.2 Infringement. (a) The Vendor agrees that it shall defend,
indemnify and hold harmless, at its own expense, all suits and claims against
the Owner for infringement or violation of any patent, trademark, copyright,
trade secret or other intellectual property rights of any third party
enforceable in the United States or in any other territory where Vendor has
approved the deployment or use of Products under this Contract (collectively,
"Intellectual Property Rights"), covering, or alleged to cover, the Products or
any component thereof. The Vendor agrees that it shall pay all sums, including
without limitation, reasonable attorneys' fees and other costs incurred at
Vendor's written request or authorization, which, in defense of, by final
judgment or decree, or in settlement of any suit or claim to which the Vendor
agrees, may be assessed against, or incurred by, the Owner on account of such
infringement or violation, provided that the Owner shall cooperate in all
reasonable respects with the Vendor and its attorneys in the investigation,
trial and defense of such lawsuit or action and any appeal arising therefrom;
provided, however, that the Owner may, at its own cost, participate in the
investigation, trial and defense of


                                       37
<PAGE>   52
such lawsuit or action and any appeal arising therefrom. The parties shall
cooperate with each other in any notifications to insurers. If a claim for
Losses (a "Claim") is to be made by a party entitled to indemnification
hereunder against the Vendor, the party claiming such indemnification shall give
written notice (a "Claim Notice") to the Vendor as soon as practicable after the
party entitled to indemnification becomes aware of any fact, condition or event
which may give rise to Losses for which indemnification may be sought under this
Agreement, provided, however, no delay on the part of the Owner in notifying the
Vendor shall relieve the Vendor from any obligation hereunder unless (and then
solely to the extent) the Vendor is thereby materially prejudiced. If any
lawsuit or enforcement action is filed against any party entitled to the benefit
of indemnity hereunder, written notice thereof shall be given to the Vendor as
promptly as practicable (and in any event within twenty (20) calendar days after
the service of the citation or summons). The Vendor shall be entitled, if it so
elects to: (i) defend such lawsuit or action; (ii) employ and engage attorneys
of its own choice to handle and defend the same, at the Vendor's cost, risk and
expense; and (iii) compromise or settle such Claim, which compromise or
settlement shall be made only with the written consent of the Owner (which may
not be unreasonably withheld), unless such compromise or settlement includes an
unconditional release of any claims against the Owner in which event such
written consent of the Owner shall not be required. If the Vendor fails to
assume the defense of such Claim within twenty (20) calendar days after receipt
of the Claim Notice, the Owner against which such Claim has been asserted will
(upon delivering notice to such effect to the Vendor) have the right to
undertake, at the Vendor's cost and expense, the defense, compromise or
settlement of such Claim on behalf of and for the account and risk of the
Vendor. In the event the Owner assumes the defense of the Claim, the Owner will
keep the Vendor reasonably informed of the progress of any such defense,
compromise or settlement. The Vendor shall be liable for any settlement of any
action effected pursuant to and in accordance with this Agreement and for any
final judgment (subject to any right of appeal), and the Vendor agrees to
indemnify and hold harmless the Owner from and against any Losses by reason of
such settlement or judgment.

            (b) The Vendor's obligation under this subsection shall not extend
to alleged infringements or violations that arise because the Products provided
by the Vendor are used in combination with other products furnished by third
parties and where any such combination was not installed, recommended or
approved by the Vendor.

            15.3 Vendor's Obligation to Cure. If in any such suit so defended,
all or any part of the Products or any component thereof is held to constitute
an infringement or violation of Intellectual Property Rights of others and its
use is enjoined, or if in respect of any claim of infringement or violation the
Vendor deems it advisable to do so, the Vendor shall at its sole cost, expense
and option take one or more of the following actions: (i) procure the right to
continue the use of the same without interruption for the Owner; (ii) replace
the same with non-infringing Products that meets the Specifications in
accordance with the terms of this Contract; or (iii) modify said Products, any
System or any component thereof so as to be non-infringing, provided that the
Products, any System or any component thereof as modified meets all of the
Specifications. In the event that the Vendor is not able to cure the
infringement pursuant to clause (i), (ii) or (iii) in the immediately preceding


                                       38
<PAGE>   53
sentence, in addition to the other rights and remedies provided in this Section
15, the Vendor shall refund to the Owner the full purchase price paid by the
Owner for such infringing Product or feature, and the Owner shall be under no
obligation to return to the Vendor such infringing Product or feature regardless
of whether, or by what means, the Owner, on its own or otherwise, subsequently
cures such infringement, unless Owner is directed to do so by court order.

            15.4 Vendor's Obligations. The Vendor's obligations under this
Section 15 shall not apply to any infringement or violation of Intellectual
Property Rights caused by unauthorized modification of the Products, any System
or any component thereof by the Owner, or arises from adherence to instructions
to apply Owner's trademark, trade name or other company identification to a
Product, or any infringement caused solely by the Owner's use and maintenance of
the Products other than in accordance with the Specifications, except as
authorized or permitted by the Vendor. The Owner shall indemnify the Vendor
against all liabilities and costs, including reasonable attorneys' fees, for
defense and settlement of any and all claims against the Vendor for
infringements or violations based upon this subsection.

            15.5 Liability of Vendor. The Liability of Vendor with respect to
any and all claims, actions, proceedings or suits by third parties alleging
infringement of patents, trademarks, or copyrights or violation of trade secrets
or proprietary rights because of, or in connection with, any items furnished
pursuant to this Contract shall be limited to the specific undertakings
contained in this Section 15.

            SECTION 16. DELAY

            16.1 Liquidated Damages. The parties agree that damages for delay
are difficult to calculate accurately and not reasonably determinable at the
time of execution of this Contract, and, therefore, agree that liquidated
damages (the "Liquidated Damages") shall be paid for non-performance or late
performance of the Vendor's obligations to achieve a Guaranteed Substantial
Completion Date for reasons not otherwise excused by Force Majeure or Owner's
failure to satisfy its obligations set out in this Contact. The parties agree
that Liquidated Damages are intended to compensate Owner for the delayed or late
performance by the Vendor and are not a penalty.

            16.2 Delay and Default. In the event the Vendor fails to achieve
(other than as permitted by this Contract) the Substantial Completion of a
System on or before the Guaranteed Substantial Completion Date for such System
or during a ten day cure period following such date, the Vendor shall pay,
weekly in arrears, for the next [*] commencing on the eleventh day after the
Guaranteed Substantial Completion Date, Liquidated Damages to the Owner in an
amount equal to [*] (pro-rated on a daily basis for periods of time less than
one week) of the total amount of all Purchase Orders relating to the System with
respect to which the Vendor has so failed, based on the number of days elapsed
after a ten day cure period following the Guaranteed Substantial Completion Date
and before the achievement of Substantial Completion;

[*]  Certain material (included by an asterisk) has been omitted from this
     document pursuant to a request for confidential treatment. The omitted
     material has been filed separately with the Securities and Exchange
     Commission.


                                       39
<PAGE>   54
provided that in the event that Substantial Completion is not achieved prior to
the expiration of such [*] period, thereafter Vendor shall pay, weekly in
arrears, additional Liquidated Damages to the Owner in an amount equal to [*]
(pro-rated on a daily basis for periods of time less than one week) of the total
amount of all Purchase Orders relating to the System with respect to which the
Vendor has so failed, based on the number of days elapsed after the [*]
plus ten day cure period following the Guaranteed Substantial Completion Date
and before the achievement of Substantial Completion; provided that in no event
shall the amount of Liquidated Damages so paid in respect of a System exceed [*]
of the total amount of all Purchase Orders relating to the System with respect
to which the Vendor has so failed.

            16.3 System Capacity Guarantee. [***]

            16.4 Limitation. The foregoing provisions concerning Liquidated
Damages shall not be deemed to limit the amount payable by the Vendor to the
Owner for breach of contract, except for amounts payable on account of delay as
aforesaid, provided, however


[*]  Certain material (indicated by an asterisk) has been omitted from this
     document pursuant to a request for confidential treatment. The omitted
     material has been filed separately with the Securities and Exchange
     Commission.


                                       40
<PAGE>   55
that the payment of Liquidated Damages shall be Owner's sole remedy for the
delay giving rise to the Vendor's obligation to pay the Liquidated Damages.

            16.5 Early Completion Bonus. With respect to a System, Vendor shall
be entitled to an early completion bonus from the Owner in the event that
Substantial Completion with respect to such System occurs on or prior to the
date that is [*] prior to the Guaranteed Substantial Completion Date for such
System. Such early completion bonus shall be equal to [*] (pro-rated on a daily
basis for periods of time less than one week) of the total amount of all
Purchase Orders relating to such System, based on the number of days that
Substantial Completion occurs prior the date that is [*] prior to the Guaranteed
Substantial Completion Date for such System.

            SECTION 17. FORCE MAJEURE

            17.1 Excusable Delay. (a) If the performance of this Contract, or of
any obligation hereunder except for the obligations set forth in Section 5 is
prevented, restricted or interfered with by reason of fires, breakdown of plant,
labor disputes, embargoes, government ordinances or requirements, civil or
military authorities, acts of God or of the public enemy, acts or omissions of
carriers, inability to obtain necessary materials or services from suppliers, or
other causes beyond the reasonable control of the party whose performance is
affected ("Force Majeure"), then the party affected, upon giving prompt notice
to the other party, shall be excused from such performance on a day-for-day
basis to the extent of such prevention, restriction, or interference (and the
other party shall likewise be excused from performance of its obligations on a
day-for-day basis to the extent such party's obligations relate to the
performance so prevented, restricted or interfered with); provided that the
party so affected shall use reasonable efforts to avoid or remove such cause of
non-performance and both parties shall proceed to perform their obligations with
dispatch whenever such causes are removed or cease.

            (b) The party claiming the benefit of excusable delay hereunder
shall: (i) promptly notify the other party of the circumstances creating the
failure or delay and provide a statement of the impact of such party failure or
delay; and (ii) use reasonable efforts to avoid or remove such causes of
nonperformance, excusable failure or delay. If an event of Force Majeure
prevents the Vendor from performing its obligations under this affected Purchase
Orders for a period exceeding sixty (60) days, the Owner may, upon prior written
notice to the other party, terminate any affected Purchase Orders; however, this
Contract remains in full force and effect. [To be negotiated.]

            (c) In the event of a Force Majeure which the party claiming relief
for such event has used all best efforts to resolve in accordance with the terms
of this Contract, upon the written request of either party, the other party
shall in good faith negotiate modifications, to the extent reasonable and
necessary, in scheduling and performance criteria in order to reasonably address
the impact of such Force Majeure.

<PAGE>   56
            SECTION 18. WARRANTIES

            18.1 Equipment and Services Warranty. Vendor warrants that, with
respect to each System, for a period of two (2) years from the date of
Substantial Completion, provided, however that if prior to Final Acceptance a
Major Outage occurs, the two (2) year period shall be extended by the number of
days elapsed between Substantial Completion and the date the Owner signs the
Certificate of Final Acceptance (as so determined, the "Warranty Period"), all
Equipment and Services furnished under this Contract with respect to such System
will be free of Defects and Deficiencies and shall conform to the applicable
portions of the Specifications (the "Equipment and Services Warranty"),
provided, however, that with respect to those Services for which a warranty is
set forth in an Exhibit, the warranty contained in the Exhibit shall supersede
the general Services warranty contained in this Section 18.1. With respect to
third-party manufactured Products which are not a part of a Core System, Vendor
shall furnish such Products only on a pass-through warranty basis; provided,
however, that Vendor shall identify such Products to Owner before acceptance of
any Purchase Order which includes any such Products. The terms of the warranty
applicable to such Products shall be provided in an addendum to the Purchase
Order. Except as noted in the B Exhibits, all Products referenced in the B
Exhibits qualify as Vendor-warranted Products. The Vendor's obligations with
respect to the Equipment and Services Warranty shall be to attempt first to
repair or replace at no additional cost, any defective Equipment or correct any
deficient Services. If, after using its best efforts to repair or replace such
Product and after consultation with and with the consent of Owner, which consent
shall not be unreasonably withheld, Vendor determines that it is unable to
repair, replace or otherwise correct such defect, Vendor shall provide a credit
or refund based on the original purchase price, and installation charges if
installed by Vendor. If, as a result of the Defect and Deficiency, the Product
fails to operate in accordance with the Specifications which causes the System
to fail to materially operate in accordance with its Specifications, a refund
shall be paid to the Owner on account of the purchase price for the total
System, less a pro-rata discount calculated with regard to the period of time
during the Warranty Period that Owner operated the System in In Revenue Service.
For purposes of calculating such pro rata discount, the period of time the Owner
would have been able to operate the System within In Revenue Service shall be:
(i) ten (10) years from Substantial Completion for the AXE switch; and (ii)
seven (7) years from Substantial Completion for all other Products. In the event
that Vendor pays a refund hereunder, Owner shall return such Products to Vendor
at Vendor's sole cost and expense. The Warranty Period for all Equipment or
Services repaired, replaced or corrected under the Equipment and Services
Warranty shall be the longer of: (i) one (1) year from the date of delivery of
the repaired or replacement Equipment or from the completion of the corrected
Services, as applicable; or (ii) or the unexpired term of the Warranty Period.
The Warranty Period for Equipment purchased as spares shall be two (2) years
from installation of such Equipment.

      For those Products not readily returnable by Owner, or where Owner cannot
remove and reinstall the Products without incurring significant time and
expense, and where Vendor elects to repair or replace the Product, Vendor shall
repair or replace the Product at Owner's Site. In the event Vendor does the
repair work at Owner's site, Vendor shall be responsible


                                       42
<PAGE>   57
for replacement of cable and wire Products, and for reasonable Site restoration.
If Vendor has elected to repair or replace a defective Product, and the Product
is readily returnable by Owner without incurring significant work or expense,
Owner is responsible for removing and reinstalling the Products. Products
returned for repair or replacement will be accepted by Vendor only in accordance
with its instructions and procedures for such returns. The transportation
expense associated with returning such Product to Vendor shall be borne by
Owner. Vendor shall pay the cost of transportation of the repaired or replacing
Product to the return destination designated by Owner. Defective or
nonconforming Products or parts which are replaced hereunder shall become
Vendor's property. Vendor may use either the same or functionally equivalent
new, remanufactured, reconditioned or refurbished Products or parts in the
furnishing of repairs or replacements under this Contract, provided that such
Products satisfy the Specifications.

            18.2 Expansions Warranty. Vendor warrants that, with respect to
Products and Services constituting Expansions (including Expansions to a System,
or Expansions or growth not part of a System, and all other purchased Products)
furnished under this Contract will be free of Defects and Deficiencies and shall
conform the applicable portions of the Specifications (the "Expansions
Warranty"). The warranty period with respect to such Products and Services shall
be two (2) years from the date of installation completion or completion of
Services, as the case may be (the "Expansions Warranty Period"). With respect to
third-party manufactured Products which are not a part of a Core System, Vendor
shall furnish such Products only on a pass-through warranty basis; provided,
however, that Vendor shall identify such Products to Owner before acceptance of
any Purchase Order which includes any such Products. The terms of the warranty
applicable to such Products shall be provided in an addendum to the Purchase
Order. Except as noted in the B Exhibits, all Products referenced in the B
Exhibits qualify as Vendor-warranted Products. The Vendor's obligations with
respect to the Expansions Warranty shall be to attempt first to repair or
replace at no additional cost, any defective Equipment or correct any deficient
Services. If, after using its best efforts to repair or replace such Product and
after consultation with and with the consent of Owner, which consent shall not
be unreasonably withheld, Vendor determines that it is unable to repair, replace
or otherwise correct such defect, Vendor shall provide a credit or refund based
on the original purchase price, and installation charges if installed by Vendor.
The warranty period for all Equipment or Services repaired, replaced or
corrected under the Expansions Warranty shall be the longer of: (i) one (1) year
from the date of delivery of the repaired or replacement Equipment or from the
completion of the corrected Services, as applicable; or (ii) or the unexpired
term of the Expansions Warranty Period. The Warranty Period for Equipment
purchased as spares shall be two (2) years from installation of such Equipment.

      For those Products not readily returnable by Owner, or where Owner cannot
remove and reinstall the Products without incurring significant time and
expense, and where Vendor elects to repair or replace the Product, Vendor shall
repair or replace the Product at Owner's Site. In the event Vendor does the
repair work at Owner's site, Vendor shall be responsible for replacement of
cable and wire Products, and for reasonable Site restoration. If Vendor has
elected to repair or replace a defective Product, and the Product is readily
returnable by Owner without incurring significant work or expense, Owner is
responsible for removing


                                       43
<PAGE>   58
and reinstalling the Products. Products returned for repair or replacement will
be accepted by Vendor only in accordance with its instructions and procedures
for such returns. The transportation expense associated with returning such
Product to Vendor shall be borne by Owner. Vendor shall pay the cost of
transportation of the repaired or replacing Product to the return destination
designated by Owner. Defective or nonconforming Products or parts which are
replaced hereunder shall become Vendor's property. Vendor may use either the
same or functionally equivalent new, remanufactured, reconditioned or
refurbished Products or parts in the furnishing of repairs or replacements under
this Contract, provided that such Products satisfy the Specifications.

            18.3 Software Warranty. Vendor warrants that, with respect to each

Deficiencies and shall conform to the applicable portions of the Specifications
(the "Software Warranty"). The Vendor's obligations with respect to the Software
Warranty shall be to attempt first to repair or replace at no additional cost,
any defective Software. If, after using its best efforts to repair or replace
such Software and after consultation with and with the consent of Owner, which
consent shall not be unreasonably withheld, Vendor determines that it is unable
to repair, replace or otherwise correct such defect, Vendor shall provide a
credit or refund based on the original purchase price, and installation charges
if installed by Vendor. If, as a result of the Defect and Deficiency, the
Software fails to operate in accordance with the Specifications which causes the
System to fail to materially operate in accordance with its Specifications, a
refund shall be paid to Owner on account of the purchase price for the total
System, less a pro rata discount calculated with regard to the period of time
during the Warranty Period that Owner operated the System in In Revenue Service.
For purposes of calculating such pro rata discount, the period of time the Owner
would have been able to operate the System in In Revenue Service shall be: (i)
ten (10) years from Substantial Completion for the AXE switch; and (ii) seven
(7) years from Substantial Completion for all other Products. In the event that
Vendor pays a refund hereunder, Owner shall return such Products to Vendor. The
warranty period for all Software so corrected or replaced under the Software
Warranty shall be the longer of: (i) one (1) year from the date of delivery of
the repaired or replacement Software; or (ii) or the unexpired term of the
Warranty Period. Vendor shall be solely responsible for all costs and expenses
incurred by Owner or Vendor in connection with the de-installation, removal and
transportation of defective Software under the Software Warranty and for the
transportation and installation of repaired, corrected or replacement Software,
including without limitation any additional or upgraded Equipment or processing
capability necessary to run or operate such repaired, corrected or replacement
Software. The Warranty Period with respect to Software Maintenance Releases,
Software Upgrades, Software Enhancements and Software Combined Releases shall be
two (2) years from the successful installation [To be negotiated.] of such
Software Maintenance Releases, Software Upgrades, Software Combined Releases and
Software Enhancements.

                  warranty) or strict liability of Vendor, any Subcontractor or

                  representatives; or

            (d)   any claim, demand, charge, action, cause of action or other

Vendor fails to assume the defense of such Claim within twenty (20) calendar
days after receipt of the Claim Notice, the Owner against which such Claim has
been asserted will (upon delivering notice to such effect to the Vendor) have
the right to undertake, at the Vendor's cost and expense, the defense,
compromise or settlement of such Claim on behalf of and for the account and risk
of the Vendor. In the event the Owner assumes the defense of the Claim, the
Owner will keep the Vendor reasonably informed of the progress of any such
defense, compromise or settlement. The Vendor shall be liable for any settlement
of any action effected pursuant to and in accordance with this Agreement and for
any final judgment (subject to any right of appeal), and the Vendor agrees to
indemnify and hold harmless the Owner from and against any Losses by reason of
such settlement or judgment.

      construction and erection data, start-up and testing data, materials, and
      Products that shall become part of such unfinished System and/or the
      specified Systems, which Vendor would otherwise have been required to
      deliver to Owner pursuant to the terms of this Contract but for the
      breach, under reasonably appropriate non-disclosure agreements; or

                  (ii) direct that the Vendor assign its Subcontractor
      agreements to the Owner without any change of price or conditions therein
      or penalty or payment therefor.

            (c) In the event of any termination of this Contract by Owner in
connection with a Vendor Event of Default, Owner shall have no liability for any
failure to satisfy the Minimum Purchase Commitment prior to such termination.

            24.4 Discontinuance of Work. Upon such notification of termination,
the Vendor shall immediately discontinue all of the Work (unless such notice of
termination directs otherwise), and, as more fully set forth in subsection
24.3(b), deliver to the Owner copies of all data, drawings, specifications,
reports, estimates, summaries, and such other information, and materials as may
have been accumulated by the Vendor in performing the Work, whether completed or
in process, which Vendor would otherwise have been required to deliver to Owner
pursuant to this Contract but for the breach. Furthermore, the Vendor shall
assign, assemble and deliver to the Owner all purchase orders and Subcontractor
agreements requested by the Owner.

            24.5 Payments. If the Owner terminates this Contract pursuant to
subsection 24.2, the Vendor shall not be entitled to receive further payment
other than payments due and payable under this Contract and not subject to
dispute prior to such termination (provided that any such disputed amounts shall
be paid by the Owner when and if such dispute is in fact resolved).
Notwithstanding anything herein to the contrary, the Owner may withhold
payments, if any, to the Vendor for the purposes of offset of amounts


                                       53
<PAGE>   68
owed to the Owner pursuant to the terms of this Contract until such time as the
exact amount of damages due the Owner from the Vendor is fully determined by a
court of competent jurisdiction.

            24.6 Continuing Obligations. Termination of this Contract for any
reason (i) shall not relieve either party of its obligations with respect to the
confidentiality of the Proprietary Information as set forth in subsection 26.18;
(ii) shall not relieve either party of any obligation which applies to it and
which expressly or by implication survives termination; and (iii) except as
otherwise provided in any provision of this Contract expressly limiting the
liability of either party, shall not relieve either party of any obligations or
liabilities for loss or damage to the other party arising out of or caused by
acts or omissions of such party prior to the effectiveness of such termination
or arising out of its obligations as to portions of the Work already performed
or of obligations assumed by the Vendor prior to the date of such termination.

            24.7 Vendor's Right to Terminate. The Vendor shall have the option
to terminate this Contract without any penalty or payment obligations, other
than undisputed payment obligations outstanding as of the date of any such
termination pursuant to the terms of this Contract if:

            (a) the Owner (i) files a voluntary petition in bankruptcy or has an
      involuntary petition in bankruptcy filed against it that is not dismissed
      within sixty (60) days of such involuntary filing: (ii) admits the
      material allegations of any petition in bankruptcy filed against it; (iii)
      is adjudged bankrupt; (iv) makes a general assignment for the benefit of
      its creditors, or if a receiver is appointed for all or a substantial
      portion of its assets and is not discharged within sixty (60) days after
      his appointment; or (v) commences any proceeding for relief from its
      creditors in any court under any state insolvency statutes, and any such
      filing, proceeding, adjudication or assignment as described herein above
      shall otherwise materially impair the Owner's ability to perform its
      obligations under this Contract; or

            (b) the Owner fails to make payments of undisputed amounts due to
      the Vendor pursuant to the terms of this Contract which are more than
      sixty (60) days overdue, provided that such failure has continued for at
      least thirty (30) days after the Vendor has notified the Owner of its
      right and intent to so terminate on account of such overdue amount; and
      provided, further, that such failure to make undisputed payments to Vendor
      shall not arise out of or relate to a termination of or credit
      restrictions under the Vendor Financing, or

            (c) the Owner materially breaches any provision of this Contract
      other than a breach to which subsection 24.7(b) is applicable, and after
      the Vendor having provided thirty (30) days' prior written notice, the
      Owner shall have failed to: (i) commence to cure the default within five
      (5) Business Days of delivery of such notice; and (ii) diligently pursue
      such cure and remedy the breach entirely.

            24.8 Special Termination Events. (a) Neither the Vendor nor the
Owner shall be obligated to perform under this Contract, except as specifically
provided, in the event that financing for the purpose of acquiring any System
sufficient to cover Owner's current payment obligations hereunder has not been
finalized with the Vendor on terms and conditions reasonably satisfactory to the
Owner. Unless acceptable financing is available, either party may terminate this
Contract without recourse, except as noted below, by notifying the other party
in writing. Further, the parties agree that the delivery and performance
schedules shall be extended by the period of time required to secure acceptable
financing. In the event of a termination of this Contract pursuant to this
subsection the Owner shall remain liable for amounts due to the Vendor for all
Work performed or Products delivered by the Vendor or any of its Subcontractors
pursuant to the specific terms of this Contract which had been directly
delivered to or performed for the Owner and/or any of its facilities or Sites in
accordance with the terms of this Contract. Any amounts owed by the Owner for
Work done or Products delivered by the Vendor during such interim period not
otherwise invoiced to the Owner by the Vendor prior to the termination of such
interim period, shall be invoiced to the Owner by the Vendor within thirty (30)
days. In no event shall the Owner be liable to the Vendor due to a termination
of this Contract pursuant to this subsection for satisfaction of the Minimum
Purchase Commitment or for any of the Vendor's direct or indirect costs or
expenses incurred in connection with any supplies or equipment ordered by the
Vendor or agreements entered into by the Vendor in order to enable it to fulfill
its obligations hereunder or in connection with the establishment of and/or
upgrade to its manufacturing, personnel, engineering, administrative or other
capacities and/or resources in contemplation of or pursuant to its performance
in accordance with the terms of this Contract. Any amounts due to the Vendor
pursuant to this subsection shall be limited in all cases to Work actually done
or Products or Services actually delivered to the Owner, its Sites or its
facilities.

            (b) If at any time after the Effective Date any material change
shall have occurred in any Applicable Law or in the interpretation thereof by
any Governmental Entity, or there shall be rendered any decision in any judicial
or administrative case or proceeding, in either case which, in the reasonable
opinion of the Owner would make the Owner's use of any part of any System
illegal or would subject the Owner or any of its Affiliates to any material
penalty, other material liability or onerous condition or to any burdensome
regulation by any Governmental Entity or otherwise render the use of such System
economically nonviable, then, with respect to such System, or affected part
thereof, or with respect to all Systems if so affected, the Owner may terminate
this Contract without charge or penalty of any kind; provided that (i) the Owner
gives the Vendor prior written notice of any such change or decision and (ii)
that the Owner uses its reasonable efforts for a reasonable time to reverse or
ameliorate such change or decision to the extent possible or practical prior to
declaring such termination. In the event of a termination pursuant to this
subsection, payment obligations incurred by the Owner for Work actually done or
Products or Services actually delivered by the Vendor prior to such termination
pursuant to this Contract shall be payable by the Owner to the Vendor on the
same terms and subject to the limitations set forth in subsection 24.8(a) above.

            SECTION 25. SUSPENSION

            25.1 Owner's Right to Suspend Work. The Owner may at any time issue
a Change Order to the Vendor to suspend all or any part of the Work for such
period of time as the Owner may reasonably determine to be appropriate. Any such
Change Order shall be handled in accordance with the provisions of Section 11
hereof.

            SECTION 26. MISCELLANEOUS

            26.1 Amendments. The terms and conditions of this Contract may only
be amended by mutually agreed contract amendments. Each amendment shall be in
writing and shall identify the provisions to be changed and the changes to be
made. Contract amendments shall be signed by duly authorized representatives of
each of the Vendor and the Owner.

            26.2 Owner Liabilities. Vendor understands and agrees that no third
party shall guarantee or otherwise be in any way liable with respect to any
obligations or liabilities of the Owner or any of its affiliates pursuant to
this Contract.

            26.3 Offset. The Vendor hereby waives any right of offset of amounts
owed by the Owner to the Vendor pursuant to the terms of this Contract.

            26.4 Assignment. The Owner may assign this Contract, or any part
hereof, to any affiliate of Owner without the Vendor's approval or consent.
Subject to the foregoing and except as otherwise permitted herein, neither this
Contract nor any portion hereof may be assigned by either party without the
express prior written consent of the other party. The Owner may, without the
consent of the Vendor, collaterally assign its rights hereunder (including but
not limited to all licenses with respect to the Software) to any or all parties
providing financing for any part of a System for the benefit of the Vendor and
one or more other entities providing financing for any part of a System or
similar arrangement for the benefit of the Vendor and one or more other entities
providing for the financing for any part of a System, in either case, which
arrangement, as the case may be, is reasonably acceptable to the Vendor in
accordance with the terms of the financing documents. If requested by the Owner,
the Vendor shall within seven (7) calendar days of such request provide a
written consent to any such assignment; provided that such consent shall permit
reassignment if the financing parties exercise their remedies under the
documents for such financing subject to reasonable standards as to: (i) the
creditworthiness of the assignee; and (ii) the fact that the assignee is not at
such time a direct competitor of the Vendor involved in the manufacture of
communications equipment, software or related services. The foregoing rights and
obligations are in addition to those set forth elsewhere in this Contract. Any
attempted assignment in violation of the terms of this Contract shall be null
and void. Subject to the foregoing, this Contract shall bind and inure to the
benefit of the parties to this Contract, their successors and permitted assigns.
Notwithstanding the foregoing, Vendor shall have the right to assign this
Contract to its affiliate, Ericsson Inc.; provided however, such


                                       56
<PAGE>   71
assignment shall not relieve Vendor of its obligations hereunder or cause Owner
to incur any additional costs or expenses.

            26.5 Notices. Except as otherwise expressly stated herein, all
notices, requests, demands and other communications which are required or may be
given under this Contract shall be in writing and shall be deemed to have been
duly given when received if personally delivered; when transmitted if
transmitted by telecopy, electronic or digital transmission method; the day

            26.12 Waiver. Unless otherwise specifically provided by the terms of
this Contract, no delay or failure to exercise a right resulting from any breach
of this Contract shall impair such right or shall be construed to be a waiver
thereof, but such right may be exercised from time to time as may be deemed
expedient. If any representation, warranty or covenant contained in this
Contract is breached by either party and thereafter waived by the other party,
such waiver shall be limited to the particular breach so waived and not be
deemed to waive any other breach under this Contract.

            26.13 Public Statements and Advertising. (a) Neither party shall
issue any public statement (or any private statement unless required in the
performance of the Work) relating to or in any way disclosing any aspect of the
Work or any System including the scope, the specific terms of this Contract,
extent or value of the Work or any System. Express written consent of the other
party is required prior to the invitation of or permission to any reporter or
journalist to enter upon the System or any part thereof. The Vendor agrees not
to use for publicity purposes any photographs, drawings and/or materials
describing any System without obtaining the prior written consent of the Owner,
which consent shall not be unreasonably withheld. The Owner agrees not to use
for publicity purposes any photographs, drawings and/or materials describing the
Vendor's products and services without obtaining the prior written consent of
the Vendor, which consent shall not be unreasonably withheld. This subsection
shall not prohibit the provision of necessary information to prospective
Subcontractors and the Vendor's or the Owner's personnel, agents or consultants
or other disclosures which are required by Applicable Law, including without
limitation federal and state securities laws and regulations. All other such
public disclosures by a party require the written consent of the other party.

            (b) Each party shall submit to the other proposed copies of all
advertising (other than public statements or press releases) wherein the name,
trademark or service mark of the other party or its affiliates is mentioned; and
neither party shall publish or use such advertising without the other party's
prior written approval. Such approval shall be granted as promptly as possible
and shall not be unreasonably withheld. The parties acknowledge that the
obtaining of prior written approval for each such use pursuant to this
subsection may be an administrative burden. At the request of either party, the

specified therein. Such guidelines shall be subject to change from time to time
at the reasonable request of either party.

            26.14 Records and Communications. Procedures for keeping and

            26.15 Ownership of Specifications. The Specifications shall
constitute the Proprietary Information of each party to the extent of each
party's contribution to the Specifications. Neither party shall use those parts
of the Specifications contributed by the other party or any part of the
Proprietary Information of the other party for any purpose other than fulfilling
or exercising their respective rights or obligations under this Agreement.

            26.16 Financing Requirements. The Vendor acknowledges that the
attainment of financing for construction of the System may be subject to
conditions that are customary and appropriate for the providers of such
financing. Therefore, the Vendor agrees to promptly consider any reasonable
amendment to or modification or assignment of this Contract required by such
providers (including, without limitation, any pertinent industrial development
authority or other similar governmental agency issuing bonds for financing of
the System) which do not materially modify the scope of the Vendor's Work in
order to obtain such financing. In the event that any such amendment or
modification materially increases the Vendor's risk or costs hereunder, the
Owner and the Vendor shall negotiate in good faith to adjust pricing matters,
and to equitably adjust such other provisions of this Contract, if any, which
may be affected thereby, to the extent necessary to reflect such increased risk
or costs. In no event shall the Vendor be required to accept any modification or
amendment pursuant to this subsection provide it has a commercially reasonable
basis for such refusal.

            26.17 Owner Review, Comment and Approval. To the extent that various
provisions of this Contract provide for the Owner's review, comment, inspection,
evaluation, recommendation or approval, the Owner may at its option do so in
conjunction and/or consultation with the Vendor. To the extent that this
Contract requires the Owner to submit, furnish, provide or deliver to the Vendor
any report, notice, Change Order, request or other items, the Owner may at its
option and upon written notice to the Vendor designate a representative to
submit, furnish, provide or deliver such items as the Owner's agent therefor. To
the extent that various provisions of this Contract provide that the Owner may
order, direct or make requests with respect to performance of the Work or is
provided access to the System sites or any other site, the Owner may at its
option and upon written notice to the Vendor authorize a representative to act
as the Owner's agent therefor. Upon receipt of such notice, the Vendor shall be
entitled to rely upon such authorization until a superseding written notice from
the Owner is received by the Vendor.

            26.18 Confidentiality. (a) All information which is identified as
proprietary or confidential by the disclosing party, including without
limitation all oral and written information (including but not limited to
determinations or reports by arbitrators pursuant to the terms of this
Contract), disclosed to the other party is deemed to be confidential, restricted
and proprietary to the disclosing party (hereinafter referred to as "Proprietary
Information"). Each party agrees to use the Proprietary Information received
from the other party only for the purpose of this Contract. Except as specified
in this Contract, no other rights, and particularly licenses, to trademarks,
inventions, copyrights, patents, or any other intellectual property rights are
implied or granted under this Contract or by the conveying of Proprietary
Information between the parties. Proprietary Information supplied is not to be
reproduced in any form except as required to accomplish the intent of, and in
accordance


                                       60
<PAGE>   75
with the terms of, this Contract. The receiving party shall provide the same
care to avoid disclosure or unauthorized use of Proprietary Information as it
provides to protect its own similar proprietary information but in no event
shall the receiving party fail to use reasonable care under the circumstances to
avoid disclosure or unauthorized use of Proprietary Information. All Proprietary
Information shall be retained by the receiving party in a secure place with
access limited to only such of the receiving party's employees, subcontractors
or agents who need to know such information for purposes of this Contract and to
such third parties as the disclosing party has consented to by prior written
approval. All Proprietary Information, unless otherwise specified in writing (i)
remains the property of the disclosing party, (ii) shall be used by the
receiving party only for the purpose for which it was intended, and (iii) such
Proprietary Information, including all copies of such information, shall be
returned to the disclosing party or destroyed after the receiving party's need
for it has expired or upon request of the disclosing party, and, in any event,
upon termination of this Contract. At the request of the disclosing party, the
receiving party shall furnish a certificate of an officer of the receiving party
certifying that Proprietary Information not returned to disclosing party has
been destroyed. For the purposes hereof, Proprietary Information does not
include information which:

            (i)   is published or is otherwise in the public domain through no
                  fault of the receiving party at the time of any claimed
                  disclosure or unauthorized use by the receiving party;

            (ii)  prior to disclosure pursuant to this Contract is properly
                  within the legitimate possession of the receiving party as
                  evidenced by reasonable documentation to the extent
                  applicable;

            (iii) subsequent to disclosure pursuant to this Contract is lawfully
                  received from a third party having rights in the information
                  without restriction of the third party's right to disseminate
                  the information and without notice of any restriction against
                  its further disclosure;

            (iv)  is independently developed by the receiving party or is
                  otherwise received through parties who have not had, either
                  directly or indirectly, access to or knowledge of such
                  Proprietary Information;

            (v)   is transmitted to the receiving party after the disclosing
                  party has received written notice from the receiving party
                  after termination or expiration of this Contract that it does
                  not desire to receive further Proprietary Information;

            (vi)  is obligated to be produced under order of a court of
                  competent jurisdiction or other similar requirement of a
                  Governmental Entity, so long as the party required to disclose
                  the information provides the other party with prior notice of
                  such order or requirement and its cooperation to the extent
                  reasonable in preserving its confidentiality; or


                                       61
<PAGE>   76
            (vii) the disclosing party agrees in writing is free of such
                  restrictions.

            (b) Because damages may be difficult to ascertain, the parties
agree, without limiting any other rights and remedies specified herein, an
injunction may be sought against the party who has breached or threatened to
breach this subsection. Each party represents and warrants that it has the right
to disclose all Proprietary Information which it has disclosed to the other
party pursuant to this Contract, and each party agrees to indemnify and hold
harmless the other from all claims by a third party related to the wrongful
disclosure of such third party's proprietary information.

            26.19 Entirety of Contract; No Oral Change. This Contract and the
Exhibits and Schedules referenced herein constitute the entire contract between
the parties with respect to the subject matter hereof, and supersede all
proposals, oral or written, all previous negotiations, and all other
communications between the parties with respect to the subject matter hereof. No
modifications, alterations or waivers of any provisions herein contained shall
be binding on the parties hereto unless evidenced in writing signed by duly
authorized representatives of both parties as set forth in this Contract.

            26.20 Relationship of the Parties. Nothing in this Contract shall be
deemed to constitute either party a partner, agent or legal representative of
the other party, or to create any fiduciary relationship between the parties.
The Vendor is and shall remain an independent contractor in the performance of
this Contract, maintaining complete control of its personnel, workers,
Subcontractors and operations required for performance of the Work. This
Contract shall not be construed to create any relationship, contractual or
otherwise, between the Owner and any Subcontractor, except to establish Owner as
a third party beneficiary of the Vendor's contacts with Subcontractors as

accrued and capitalized interest and expenses Purchaser owes to Vendor in
connection with forbearances made by Vendor to Purchaser under the Deferred
Payment Agreement. Subject to the terms and conditions, and subject to the
limitations, herein set forth, Vendors agree, in accordance with this SECTION 2,
to make a Forbearance in the full amount of the Deferred Payment Balance
("Deferred Payment Balance Forbearance") as of the date hereof, which amount
shall be repaid in accordance with the terms and conditions set forth herein.

        2.2 CAPITALIZED INTEREST FACILITY.

               (a) CAPITALIZED INTEREST FORBEARANCE COMMITMENTS. Subject to the
terms and conditions, and subject to the limitations, herein set forth, each
Capitalized Interest Vendor, severally and for itself alone, agrees to make
Capitalized Interest Forbearances to Purchaser in amounts equal to such Vendor's
Capitalized Interest Commitment Percentage from time to time. At no time shall
the aggregate amount of outstanding Capitalized Interest Forbearances exceed the
Capitalized Interest Commitment.

               (b) TYPES OF CAPITALIZED INTEREST FORBEARANCES. Capitalized
Interest Forbearances shall be available to Purchaser for (i) interest payments
to Vendors on the Deferred Payment Balance Forbearance, (ii) interest payments
on earlier Capitalized Interest Forbearances and (iii) paying the Commitment Fee
set forth in SECTION 2.8(b).

               (c) CAPITALIZED INTEREST FORBEARANCE AVAILABILITY. Capitalized
Interest Forbearances shall be available from the Operative Date through the
Final Availability Date, in an aggregate amount not exceeding the Aggregate
Capitalized Interest Commitment; provided, however, that no Vendor shall be
required to make any Capitalized Interest Forbearance when there exists an Event
of Default or an Unmatured Event of Default. Capitalized Interest Forbearances
drawn and repaid during the Availability Period may not be re-drawn. Any part of
the Capitalized Interest Facility undrawn at the end of the Availability Period
shall be canceled.

        2.3 TYPES OF FORBEARANCES. Each Forbearance shall, in accordance with
the terms of this Agreement, be in the form of either a Base Rate Forbearance or
a LIBOR Forbearance; provided, however, that, notwithstanding anything to the
contrary herein, the Deferred Payment Balance Forbearance shall bear interest at
the 30 days LIBOR Rate until such time as another rate is requested pursuant to
a Notice of Conversion/Continuation given in accordance with SECTION 2.6(c). At
no time may Purchaser maintain LIBOR Forbearances in more than six (6) separate
Interest Periods.

        2.4 CONVERSION AND CONTINUATION ELECTIONS. Purchaser may, upon
irrevocable written notice to Administrative Agent:

               (a) elect to convert on any Business Day, Base Rate Forbearances
in an amount equal to Two Million Five Hundred Thousand Dollars ($2,500,000) (or
any integral



                                      23.
<PAGE>   25

multiple of One Hundred Thousand Dollars ($100,000) in excess thereof) into
LIBOR Forbearances; or

               (b) elect to convert on any Interest Payment Date any LIBOR
Forbearances maturing on such Interest Payment Date (or any part thereof) into
Base Rate Forbearances; or

               (c) elect to continue on any Interest Payment Date any LIBOR
Forbearances maturing on such Interest Payment Date (or any part thereof in an
amount equal to Two Million Five Hundred Thousand Dollars ($2,500,000) or any
integral multiple of One Hundred Thousand Dollars ($100,000) in excess thereof)
as LIBOR Forbearances;

provided, that if the aggregate amount of LIBOR Forbearances shall have been
reduced by payment, prepayment, or conversion of any part thereof, to be less
than Two Million Five Hundred Thousand Dollars ($2,500,000), such LIBOR
Forbearances shall automatically convert into Base Rate Forbearances, and on and
after such date the right of Purchaser to continue such Forbearances as, and
convert such Forbearances into, LIBOR Forbearances shall terminate.

               (d) unless all Vendors shall otherwise consent, during the
existence of an Unmatured Event of Default or Event of Default, Purchaser may
not elect to have a Forbearance converted to, or made or continued as, a LIBOR
Forbearance.

        2.5 DURATION OF INTEREST PERIODS.

               (a) Subject to the provisions of the definition of Interest
Period, the duration of each Interest Period applicable to a LIBOR Forbearance
shall be as specified in the applicable Forbearance Request or Notice of
Conversion/Continuation, as applicable.

               (b) If Administrative Agent does not receive a notice of election
of duration of an Interest Period with respect to a borrowing of LIBOR
Forbearances pursuant to SUBSECTION (a) above within the applicable time limits
specified herein, Purchaser shall be deemed to have elected to make or convert
such Forbearances in whole into Base Rate Forbearances on the last day of the
then current Interest Period with respect thereto. Notwithstanding anything to
the contrary herein, any and all LIBOR Forbearances shall be converted in whole
into Base Rate Forbearances on the last day of the then existing Interest Period
with respect thereto if Administrative Agent shall have received notice from
Purchaser or a Vendor that a default, Unmatured Event of Default or an Event of
Default exists.

               (c) Notwithstanding the foregoing, Purchaser may not select an
Interest Period that would end, but for the provisions of the definition of
Interest Period, after the applicable Final Maturity Date.

        2.6 NOTICE AND MANNER OF MAKING ADDITIONAL FORBEARANCES.

               (a) CAPITALIZED INTEREST FORBEARANCE.

                    (i) Not fewer than three (3) Business Days prior to the date
Purchaser desires to obtain a Capitalized Interest Forbearance, Purchaser shall
deliver by electronic facsimile transmission to each of Administrative Agent and
QUALCOMM, written notice specifying (A) the amount of such Capitalized Interest
Forbearance, (b) the effective date for the



                                      24.
<PAGE>   26

borrowing of such Capitalized Interest Forbearance, which notice shall be in the
form of EXHIBIT D to this Agreement (a "Capitalized Interest Forbearance
Request").

                    (ii) If Purchaser has not delivered a Capitalized Interest
Forbearance Request on or before the third Business Day prior to the next
succeeding Interest Payment Date, a Capitalized Interest Forbearance Request for
a Base Rate Forbearance shall be deemed to have been made on such date (a
"Deemed Capitalized Interest Forbearance Request") in the amount of the interest
payment to become due and payable on such Interest Payment Date.

                    (iii) Administrative Agent shall promptly notify each
Capitalized Interest Vendor as to the content of each Capitalized Interest
Forbearance Request or Deemed Capitalized Interest Forbearance Request.

               (b) CAPITALIZED INTEREST FORBEARANCE REQUEST IRREVOCABLE. Once
given, a Capitalized Interest Forbearance Request shall be irrevocable and
Purchaser shall be bound to draw a Capitalized Interest Forbearance in
accordance therewith, except as otherwise provided in this Agreement. If for any
reason a Capitalized Interest Forbearance is not made in accordance with the
Capitalized Interest Forbearance Request, Purchaser shall on demand (which may
be made through the Administrative Agent) pay to Vendor such amount (if any) as
Vendor may certify, in a certificate setting out in reasonable detail the method
and basis of computation of such amount, to be necessary to compensate it for
any loss or expense incurred in liquidating or redeploying funds arranged for
the purpose of a proposed Capitalized Interest Forbearance or in terminating any
such arrangement in respect of this Agreement or otherwise as a direct
consequence of a Capitalized Interest Forbearance not having been made in
accordance with the Capitalized Interest Forbearance Request but, in each case,
only up to and including the last day of the relevant interest period determined
in accordance with this SECTION 2.6.

               (c) CONVERSIONS/CONTINUATIONS OF FORBEARANCES. On each date on
which Purchaser desires, with respect to Forbearances to (A) continue any such
Forbearances hereunder or (B) convert any such outstanding Forbearances into
Forbearances of another type provided for in this Agreement, Purchaser shall
notify Administrative Agent (which notice shall be irrevocable) in writing by
electronic facsimile transmission received no later than 1:00 p.m. New York time
on the date one (1) Business Day before the day on which such requested
Forbearances are to be continued as or converted into Base Rate Forbearances,
and received no later than 1:00 p.m. New York time on the date three (3)
Business Days before the date on which such requested Forbearances are to be

               (d) NOTIFICATION OF VENDORS. Administrative Agent shall promptly

        2.7 SCHEDULED PAYMENT OF PRINCIPAL OF THE FORBEARANCES.

               (a) On each date set forth on SCHEDULE 2.7(a), Purchaser shall
pay that percentage of the principal amount of the Deferred Payment Balance
Forbearance outstanding on September 30, 2001 which is set forth opposite each
such date.

               (b) On each date set forth on SCHEDULE 2.7(a), Purchaser shall
pay that percentage of the principal amount of the Capitalized Interest
Forbearances outstanding on September 30, 2001 which is set forth opposite each
such date.

               (c) Any remaining unpaid Forbearances, accrued and unpaid
interest thereon and other amounts owing to Administrative Agent and Vendors
pursuant to this Agreement shall be due and payable in full at the Final
Maturity Date.

        2.8 INTEREST RATES; PAYMENT OF INTEREST; COMMITMENT FEE; CALCULATION OF
INTEREST AND FEES.

               (a) FORBEARANCES.

                    (i) BASE RATE FORBEARANCES. Each Base Rate Forbearance shall
bear interest on the outstanding principal amount thereof at a rate per annum
equal to the Base Rate plus the Applicable Margin. From the Effective Date such
interest shall be payable on each Interest Payment Date and at Maturity.

                    (ii) LIBOR FORBEARANCES. Each LIBOR Forbearance shall bear
interest on the outstanding principal amount thereof, for each Interest Period
applicable thereto, at a rate per annum equal to the LIBOR Rate plus the
Applicable Margin. From the Effective Date such interest shall be payable on
each Interest Payment Date and at Maturity.

                    (iii) DEFAULT RATE. Upon the occurrence of an Event of
Default and so long as such Event of Default shall continue, including after
acceleration (whether before or after entry of judgment), Purchaser shall pay
interest on the principal amount of each Forbearance then outstanding at the
Default Rate.

               (b) FEES. Commencing on the Effective Date and through the Final
Availability Date, Purchaser shall pay to Administrative Agent, for the ratable
benefit of Vendors, a commitment fee equal to three-eighths of one percent
(0.375%) per annum on the average daily amount of the unutilized portion of the
Aggregate Capitalized Interest Commitment ("Commitment Fee"). Such Commitment
Fee shall be payable on the last Business Day of that month which is six (6)
months following the Effective Date and continuing on the last Business Day of
each six (6) month period thereafter through the Final Availability Date. So
long as there exists no Unmatured Event of Default or Event of Default, the
Commitment Fee may be financed under the Capitalized Interest Facility.

               (c) CALCULATION OF INTEREST AND FEES. Interest on LIBOR
Forbearances and the Commitment Fee shall be computed on the basis of a 360-day
year and on the basis of a 365/366-day year for all Base Rate Forbearances and
fees for the actual number of days elapsed. In computing interest on any
Forbearance, the date of the making of such Forbearance shall be included and
the date of payment shall be excluded; provided, however, that if any
Forbearance



                                      26.
<PAGE>   28

is repaid on the same day on which it is made, such day shall be included in
computing interest on such Forbearance. Each change in the interest rate of the
Base Rate Forbearances based on changes in the Base Rate shall be effective on
the effective date of such change and to the extent of such change.
Administrative Agent shall give Purchaser prompt written notice of any such
change in the Base Rate; provided, however, that any failure by Administrative
Agent to provide Purchaser with notice hereunder shall not affect Vendors' right
to make changes in the interest rate of the Base Rate Forbearances based on
changes in the Base Rate.

        2.9 PAYMENT PROCEDURES.

               (a) PAYMENT ON BUSINESS DAYS. Whenever any payment due under this
Agreement shall fall due on a day other than a Business Day, the due date of
such payment shall be extended to the next succeeding Business Day (subject,
however, to CLAUSE (a) of the definition of Interest Period) and such payment
shall be made on such Business Day, and such extension of time shall be included
in the computation of interest.

               (b) PLACE OF PAYMENT. Purchaser shall make all payments and
prepayments under this Agreement, the Notes and Pagares, the Commitment Fee, the
prepayment fees referred to in SECTION 2.10(A) hereof, and the principal of and
interest on the Forbearances to the Administrative Agent's Payment Office, in
lawful money of the United States and in immediately available funds no later
than 1:00 p.m., New York time, on the date of payment (which must be a Business
Day). All payments received after 1:00 p.m., New York time, on any Business Day,
shall be deemed to have been received on the next succeeding Business Day. After
the occurrence and during the continuance of an Event of Default, Purchaser
authorizes Vendors to charge from time to time against any or all of Purchaser's
deposits maintained with Vendors any amount payable by Purchaser hereunder not
paid when due. Each Vendor shall promptly notify Administrative Agent of each
such charge and pay over the same to Administrative Agent for application in
accordance with this Agreement.

               (c) DISTRIBUTION OF PAYMENTS TO VENDORS BY ADMINISTRATIVE AGENT.
Upon receipt of any payment or prepayment of the Commitment Fee, the prepayment
fees referred to in SECTION 2.10(A) hereof, or the principal of and interest on
the Forbearances by or on behalf of Purchaser, Administrative Agent shall
promptly pay over to each Vendor at its Vendor Office its pro rata share of such
amount in like funds of the sum received.

               (d) LATE PAYMENTS. If any amount required to be paid by Purchaser
under this Agreement or the other Credit Documents (including without
limitation, payments and prepayments of the principal amount of Forbearances,
accrued interest and fees) is not paid when due, Purchaser shall pay interest on
the unpaid amount until such amount is paid in full at a per annum rate equal to
the Default Rate, such rate to change from time to time as the Base Rate shall
change.

               (e) APPLICATION OF PAYMENTS. Except as specifically set forth
herein, all payments under this Agreement shall be credited first to all fees
and other expenses then due to Administrative Agent and Collateral Agent, next
to all fees and other expenses then due to Vendors, next to all interest then
due, and lastly to all principal then due.



                                      27.
<PAGE>   29

               (f) DESIGNATION OF PAYMENT. When making a payment under this
Agreement, Purchaser shall clearly specify which Forbearance, fee or expense
such payment relates to and the nature of the payment.

               (g) ADMINISTRATIVE AGENT'S RIGHT TO ASSUME PAYMENTS WILL BE MADE
BY PURCHASER. Unless Administrative Agent shall have been notified by Purchaser
prior to the date on which any payment to be made by Purchaser hereunder is due
that Purchaser does not intend to remit such payment, Administrative Agent may
(in its sole and absolute discretion) assume that Purchaser has remitted such
payment when so due and Administrative Agent may (in its sole and absolute
discretion) and in reliance upon such assumption, make available to each Vendor
on such payment date an amount equal to such Vendor's Capitalized Interest
Commitment Percentage of such assumed payment. If Purchaser has not in fact
remitted such payment to Administrative Agent, each Vendor shall forthwith on
demand repay to Administrative Agent the amount of such assumed payment made
available to such Vendor, together with interest thereon in respect of each date
from and including the date such amount was made available by Administrative
Agent to such Vendor to the date such amount is repaid to Administrative Agent,
at the Federal Funds Rate.

        2.10 PREPAYMENTS OF THE FORBEARANCES; CERTAIN REQUIRED PAYMENTS;
AGGREGATE COMMITMENT REDUCTION.

               (a) VOLUNTARY PREPAYMENTS. Subject to the terms of SECTION
2.10(c), Purchaser shall have the right to prepay Forbearances in whole or in
part, without premium or penalty, from time to time on the following terms and
conditions: (i) Purchaser shall give Administrative Agent written notice (or
telephonic notice promptly confirmed in writing) of its intent to prepay
Forbearances, the amount of such prepayment and the specific Forbearance(s) such
prepayment shall apply, which notice shall be given by Purchaser no later than
1:00 p.m. (New York time) three (3) days prior to the date of such prepayment,
and which notice shall promptly be transmitted by Administrative Agent to each
of the Vendors; (ii) each partial prepayment of any Forbearance shall be in an
aggregate principal amount of at least One Million Dollars ($1,000,000) and
shall be in integral multiples of One Million Dollars ($1,000,000) in excess
thereof; (iii) each prepayment of the Forbearances shall be applied pro rata to
the scheduled principal repayments of the outstanding Forbearances at the time
of prepayment of the Forbearances among all Vendors; and (iv) any interest
accrued on the amounts so prepaid to the date of such payment shall be paid at
the time of any such payment. Any notice of prepayment given by Purchaser under
any provision of this Agreement shall be irrevocable and Purchaser shall be
bound to make a prepayment in accordance therewith. Purchaser may not prepay the
Forbearances or any part thereof except in accordance with the express terms of
this Agreement. Amounts prepaid may not be reborrowed under this Agreement.

               (b) MANDATORY PREPAYMENTS.

                    (i) PROCEEDS OF ASSET SALES. Notwithstanding the prohibition
of Asset Sales in SECTION 5.2(d) below, all Net Proceeds received by Purchaser
or any of its Subsidiaries at any time related to Asset Sales shall be paid by
Purchaser or such Subsidiaries to Administrative Agent no later than five (5)
days after receipt by Purchaser or such Subsidiary of such Net Proceeds to be
applied against the principal amount of the Forbearances then outstanding in an
amount equal to one hundred percent (100.0%) of such Net Proceeds;



                                      28.
<PAGE>   30

provided, however, that if required by the terms of the Eligible Secured Debt,
then one hundred percent (100.0%) of such Net Proceeds shall be applied pro rata
to such Eligible Secured Debt and the principal amount of the Forbearances then
outstanding. Concurrent with Purchaser's or such Subsidiary's receipt of such
Net Proceeds, the Capitalized Interest Commitment shall be reduced to reflect
the reduction of anticipated interest payments implied by such prepayment.

                    (ii) ISSUANCE OF DEBT OR EQUITY INSTRUMENTS. Net Proceeds
received by Parent, Purchaser or any of its Subsidiaries in excess of Two
Hundred Forty Five Million Dollars ($245,000,000) (reduced by the amount of
Assets Sales as determined without regard to the application of clause (b) of
the definition of Asset Sale) which are related to the public or private
issuance or sale of any debt or Capital Stock, shall be paid by Purchaser or
such Subsidiaries to Administrative Agent no later than five (5) days after
receipt by Purchaser or such Subsidiary of such Net Proceeds to be applied
against the principal amount of the Forbearances then outstanding as follows:
(A) if by issuance and sale of equity through a public offering, in an amount
equal to fifty percent (50%) of such Net Proceeds and (B) and in all other
cases, one hundred percent (100%) of the Net Proceeds aggregating in excess of
Fifty Million Dollars ($50,000,000); provided, however, that if required by the
terms of the Eligible Secured Debt, then such Net Proceeds shall be applied pro
rata to such Eligible Secured Debt and the principal amount of the Forbearances
then outstanding. Concurrent with Purchaser's or such Subsidiary's receipt of
such Net Proceeds, the Capitalized Interest Commitment shall be reduced to
reflect the reduction of anticipated interest payments implied by such
prepayment.

                    (iii) EXCESS CASH FLOW. Fifty percent (50%) of Purchaser's
Excess Cash Flow at any time shall be promptly paid by Purchaser to
Administrative Agent to be applied against the principal amount of the
Forbearances then outstanding; provided, however, that if required by the terms
of the Eligible Secured Debt, then such Excess Cash Flow amount shall be applied
pro rata to such Eligible Secured Debt and the principal amount of the
Forbearances then outstanding. As of the end of each fiscal year, the
Capitalized Interest Commitment shall be reduced to reflect the reduction of
anticipated interest payments implied by such prepayment of Excess Cash Flow.

                    (iv) PREPAYMENT OF OTHER INDEBTEDNESS. Notwithstanding the
limitations on prepayments in SECTION 5.2(g) below, in the event Purchaser or
any of its Subsidiaries prepays any Indebtedness other than the Forbearances and
mandatory payments made pursuant to the Telex Chile Debt, then Purchaser shall
immediately prepay a portion of the Forbearances in proportion to the
outstanding balances of the other Indebtedness paid.

                    (v) FORBEARANCES IN EXCESS OF COMMITMENT. Purchaser shall
immediately prepay a portion of the Capitalized Interest Forbearances to the
extent the total outstanding balance of all Capitalized Interest Forbearances
exceeds the Aggregate Capitalized Interest Commitment.

               (c) BREAKAGE CHARGE. In the event of (i) the payment of any
principal of any LIBOR Forbearance other than on the last day of an Interest
Period applicable thereto (including as a result of an Event of Default), (ii)
the conversion of any LIBOR Forbearance other than on the last day of the
Interest Period applicable thereto, or (iii) the failure to borrow, convert,
continue or prepay any Forbearance on the date specified in any notice delivered
pursuant hereto, then, in any such event, Purchaser shall compensate each Vendor
for the loss, cost and expense



                                      29.
<PAGE>   31

attributable to such event. In the case of a LIBOR Forbearance, such loss, cost
or expense to any Vendor shall be deemed to include an amount determined by such
Vendor to be the excess, if any, of (A) the amount of interest which would have
accrued on the principal amount of such LIBOR Forbearance had such event not
occurred, at the LIBOR Rate that would have been applicable to such LIBOR
Forbearance, for the period from the date of such event to the last day of the
then current Interest Period therefor (or, in the case of a failure to borrow,
convert or continue, for the period that would have been the Interest Period for
such LIBOR Forbearance), over (B) the amount of interest which would accrue on
such principal amount for such period at the interest rate which such Vendor
would bid were it to bid, at the commencement of such period, for dollar
deposits of a comparable amount and period from other banks in the eurodollar
market. A certificate of any Vendor setting forth any amount or amounts that
such Vendor is entitled to receive pursuant to this Section shall be delivered
to Purchaser and shall be conclusive absent manifest error. Purchaser shall pay
such Vendor the amount shown as due on any such certificate within ten (10) days
after receipt thereof.

               (d) APPLICATION OF PREPAYMENTS. Mandatory prepayments of
Forbearances pursuant to this SECTION 2.10, other than mandatory prepayments
pursuant to SECTION 2.10(b)(iii) AND (iv), shall be applied in the inverse order
of scheduled principal repayments of the outstanding Forbearances at the time of
prepayment of the Forbearances. Voluntary prepayments and mandatory prepayments
of Forbearances pursuant to SECTION 2.10(b)(iii) or (iv) shall be applied pro
rata to the scheduled principal repayments of the outstanding Forbearances at
the time of prepayment of the Forbearances.

        2.11 SURVIVABILITY. All of Purchaser's obligations under this Agreement
shall survive repayment of the Notes and Pagares until all obligations of
Purchaser to make payments to Administrative Agent and Vendors under all Credit
Documents are fully satisfied and Vendors' obligations to make the Forbearances
hereunder expire. Notwithstanding the foregoing, Purchaser's obligations set
forth in SECTIONS 9.4 and 9.15 of this Agreement shall survive Purchaser's
payment of all obligations under the Credit Documents and the expiration of
Vendors' obligations to make Forbearances hereunder.

        2.12 EVIDENCE OF DEBT.

               (a) Each Vendor shall maintain in accordance with its usual
practice an account or accounts evidencing the Indebtedness of Purchaser to such
Vendor resulting from each Forbearance owing to such Vendor from time to time,
including the amounts of principal and interest payable and paid to such Vendor
from time to time hereunder in respect of such Forbearances.

               (b) Administrative Agent shall maintain accounts in which it
shall record (i) the amount of each Forbearance made hereunder and the Interest
Period applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from Purchaser to each Vendor hereunder and
(iii) the amount of any sum received by Administrative Agent hereunder for the
account of Vendors and each Vendor's share thereof.

               (c) The entries made in the accounts maintained pursuant to
paragraph (b) or (d) of this Section shall be prima facie evidence of the
existence and amounts of the obligations recorded therein; provided that the
failure of any Vendor or Administrative Agent to maintain



                                      30.
<PAGE>   32

such accounts or any error therein shall not in any manner affect the obligation
of Purchaser to repay the Forbearances in accordance with the terms of this
Agreement.

               (d) No later than the Funding Date for each Forbearance,
Purchaser shall execute before a Chilean Notary Public and deliver to
Administrative Agent to hold on behalf of the Vendor making such Forbearance a
promissory note of Purchaser payable to such Vendor substantially in the form of
EXHIBIT A, attached hereto or in form and substance reasonably satisfactory to
Purchaser and such Vendor (each a "Pagare"), with appropriate insertions as to
the issue date, principal repayment dates, principal amount, Applicable Margin
and due date (which shall not be later than Maturity), and payable to the order
of such Vendor in a principal amount equal to the Forbearance. Such Pagare shall
be jointly and severally guaranteed by the Guarantors and shall be dated the
date such Forbearance is made. Notwithstanding anything to the contrary
contained herein, upon the reasonable request of Administrative Agent at any
time, Purchaser shall promptly execute and deliver to Administrative Agent to
hold on behalf of such Vendor a replacement Pagare or an endorsement with
respect to any Pagare theretofore issued in order to conform the terms thereof
to the terms of this Agreement, which replacement Pagare or endorsement shall be
jointly and severally guaranteed by the Guarantors and shall be dated the date
on which the replacement or endorsement is to be effective. Concurrently
therewith, Administrative Agent or Vendor, as the case may be, shall return the
replaced Pagare to Purchaser. Purchaser shall bear all costs and taxes arising
from such replacement or endorsement.

               (e) Upon the written request of any Vendor, Administrative Agent
shall forward to such Vendor (i) all Pagares payable to such Vendor received by
Administrative Agent on or prior to such date (the "Request Date") within ten
(10) Business Days of receipt by Administrative Agent of such request, and (ii)
all Pagares payable to such Vendor received by Administrative Agent after the
Request Date within ten (10) Business Days of the receipt by Administrative
Agent thereof; provided that any Vendor requesting such delivery of its Pagares
shall reimburse Administrative Agent for all costs and expenses incurred by
Administrative Agent in the distribution thereof.

               (f) In the case of any conflict between the terms of this
Agreement and any Pagare, the terms of this Agreement shall control. Without
limiting the generality of the foregoing, all Forbearances made hereunder shall
accrue interest from the date such Forbearance is made and, to the extent not
evidenced by a Pagare, shall otherwise be treated as a Forbearance hereunder
irrespective of Purchaser's execution or nonexecution of any Pagare.

               (g) Upon partial repayment of any principal amount evidenced by
any Pagares, Purchaser may execute and deliver to Administrative Agent to hold
on behalf of each Vendor a replacement Pagare taking into account such
prepayment, which replacement Pagare shall be jointly and severally guaranteed
by the Guarantors and shall be dated the date on which the replacement is to be
effective. Concurrently therewith, Administrative Agent or Vendor, as the case
may be, shall return the replaced Pagare to Purchaser. Purchaser shall bear all
costs and taxes arising from such replacement.

               (h) Upon request after the payment in full of all Obligations,
Administrative Agent and Vendors, as applicable, shall return all Pagares and
Notes received by them, stamped as paid in full.



                                      31.
<PAGE>   33

               (i) In addition to the Pagares, Purchaser agrees to execute and
deliver to each Vendor, promptly upon request by such Vendor, a promissory note
evidencing Purchaser's Indebtedness to such Vendor under this Agreement in the
amount of such Vendor's Commitment ("Note"), which promissory note shall
acknowledge that the indebtedness outstanding thereunder may also be evidenced
by one or more Pagares and shall be satisfactory in form and substance to such
Vendor and Administrative Agent and shall be consistent with the terms of this
Agreement.

               (j) If any Vendor exercises any right in any court in the
Republic of Chile under any Pagare or Note delivered pursuant to this Agreement,
it shall not be required for such purpose to evidence to Purchaser or any other
Person that such Pagare or Note represents Obligations of the Purchaser under
this Agreement nor that any condition herein has been fulfilled. Notwithstanding
discharge in full of any Pagare or Note, if the amount (including, without
limitation, default interest) paid or payable to any of the Vendors under such
Pagare or Note (whether arising from the enforcement thereof in the Republic of
Chile or otherwise) is less than the amount due and payable to such Vendor in
accordance with this Agreement with respect to the Forbearance, or portion
thereof, evidenced by such Pagare or Note, Purchaser agrees to pay to such
Vendor upon demand such difference.

        2.13 NET PAYMENTS. Purchaser's obligation to make payments and perform
all other obligations hereunder, and the rights of Administrative Agent,
Collateral Agent and Vendors in and to such payments and performance, shall be
absolute and unconditional and shall not be subject to any abatement, reduction,
set-off, defense, counterclaim or recoupment for any reason whatsoever,
including, without limitation, abatements or reductions due to any present or
future claims of Purchaser against Administrative Agent, Collateral Agent or any
Vendor under this Agreement, the Equipment Agreements or otherwise, against any
vendor of equipment or services used or planned to be used, or against any other
Person for whatever reason. Except as otherwise expressly provided herein, this
Agreement shall not terminate, nor shall the obligations of Purchaser be
affected, by reason of (a) any defect in or damage to, or any loss or
destruction of, any of the equipment or services provided pursuant to the
Equipment Agreements or otherwise from any cause whatsoever; (b) any bankruptcy,
insolvency, reorganization or other proceeding relating to, or any action taken
by any trustee or receiver of, Administrative Agent, Collateral Agent, any
Vendor or any other Person; or (c) for any other cause, whether similar or
dissimilar to the foregoing, any present or future law or regulation to the
contrary notwithstanding, whether or not such cause shall give rise to a claim
by Purchaser against any Vendor or any other Person under the Equipment
Agreements or otherwise, it being the express intention of the parties hereto
that all amounts payable by Purchaser hereunder shall be, and continue to be,
payable in all events unless the obligation to pay shall be terminated pursuant
to the express provisions of this Agreement. All payments made by Purchaser
hereunder as required hereby shall be final, and Purchaser shall not seek to
recover any such payment or any part thereof for any reason whatsoever. Nothing
in this Agreement shall, however, release any claim Purchaser may have against
Administrative Agent, Collateral Agent or any Vendor, whether in connection with
the Equipment Agreements or otherwise. If for any reason whatsoever this
Agreement shall be terminated in whole or in part by operation of law or
otherwise, Purchaser shall nonetheless, to the extent permitted by applicable
law, pay to Administrative Agent, on behalf of Vendors, an amount equal to each
payment payable hereunder at the time and in the manner that such payment would
have become due and payable under the terms of this Agreement if it had not been
terminated in whole or in part.

        2.14 CHANGED CIRCUMSTANCES; TAXES.

               (a) In the event that:

                    (i) on any date on which the LIBOR Rate would otherwise be
set, Administrative Agent shall have determined in good faith (which
determination shall be final and conclusive) that adequate and fair means do not
exist for ascertaining the LIBOR Rate, or

                    (ii) at any time Administrative Agent or any Vendor shall
have determined in good faith (which determination shall be final and
conclusive) that:

                         (A) the making or continuation of any Forbearance to a
LIBOR Forbearance has been made impracticable or unlawful by (1) the occurrence
of a contingency that materially and adversely affects the interbank eurodollar
market or (2) compliance by any Vendor in good faith with any applicable law or
governmental regulation, guideline or order or interpretation or change thereof
by any Governmental Authority charged with the interpretation or administration
thereof or with any request or directive of any such Governmental Authority
(whether or not having the force of law); or

                         (B) the LIBOR Rate shall no longer represent the
effective cost to any Vendor for U.S. dollar deposits in the interbank market
for deposits in which banks of the United States of America regularly
participate (including, without limitation, due to the imposition of a Reserve
Percentage);

then, and in any such event, such Vendor shall forthwith so notify
Administrative Agent and Purchaser thereof. From the date of delivery of such
notice until such Vendor reasonably determines that the circumstances giving
rise to such notice no longer apply, the obligation of Vendors to allow
selection by Purchaser of the type of Forbearance affected by the contingencies
described in this SECTION 2.14 (herein called "Affected Forbearances") shall be
suspended. If at the time Administrative Agent or a Vendor so notifies
Purchaser, Purchaser has previously given Administrative Agent a Notice of
Conversion/Continuation with respect to one or more Affected Forbearances but
such Forbearances have not yet gone into effect, such notification shall be
deemed to be void and Purchaser may request Forbearances of a non-affected type
by giving a substitute Notice of Conversion/Continuation pursuant to this
Agreement.

        Upon such date as shall be specified in such notice (which shall not be
earlier than the date such notice is given) Purchaser shall, with respect to the
outstanding Affected Forbearances (other than Affected Forbearances described in
SECTION 2.14(a)(ii)(A)(1) above), either prepay or convert the same to Base Rate
Forbearances, together with interest thereon and any amounts required to be paid
pursuant to SECTION 2.10(c) above, and may request a Forbearance of another type
in accordance with this Agreement, by giving an a Notice of
Conversion/Continuation pursuant to this Agreement; provided that any such
prepayment shall not be deemed to constitute a prepayment pursuant to SECTION
2.10 above.

               (b) In case any law, regulation, treaty or official directive or
the interpretation or application thereof by any court or by any Governmental
Authority charged with the administration thereof or the compliance with any
guideline or request of any central bank or other Governmental Authority
(whether or not having the force of law):



                                      33.
<PAGE>   35

                    (i) subjects any Vendor to any tax with respect to payments
of principal or interest or any other amounts payable hereunder by Purchaser or
otherwise with respect to the transactions contemplated hereby (except for such
taxes as are imposed on or measured by each Vendor's net income by the
jurisdiction under the laws of which such Vendor is organized or maintains a
place of business or any political subdivision thereof), or

                    (ii) imposes, modifies or deems applicable any deposit
insurance, reserve, special deposit or similar requirement against assets held
by, or deposits in or for the account of, or loans by, any Vendor (including,
without limitation, any imposition of a Reserve Percentage), or

                    (iii) imposes upon any Vendor any other condition with
respect to its performance under this Agreement,

and the result of any of the foregoing is to increase the cost to such Vendor,
reduce the income receivable by such Vendor or impose any expense upon such
Vendor with respect to any LIBOR Forbearances, such Vendor shall promptly notify
Purchaser thereof. Purchaser agrees to pay to such Vendor the amount of such
increase in cost, reduction in income or additional expense as and when such
cost, reduction or expense is incurred or determined, upon presentation by such
Vendor of a statement in the amount and setting forth such Vendor's calculation
thereof, which statement shall be deemed true and correct absent manifest error.

               (c) Any and all payments by Purchaser to each Vendor and
Administrative Agent under this Agreement and any Credit Document shall be made
free and clear of, and without deduction or withholding for, any and all present
or future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Vendor, such
taxes (including income taxes, taxes on profits and franchise taxes) as are
imposed on or measured by each Vendor's net income or profits by the
jurisdiction under the laws of which such Vendor is organized or maintains a
place of business or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").

                    (i) In addition, Purchaser shall pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement, any Pagares or any other Credit Documents (hereinafter referred to as
"Other Taxes").

                    (ii) Purchaser shall indemnify and hold harmless each Vendor
and Administrative Agent for the full amount of Taxes or Other Taxes (including
any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under
this SECTION 2.14) paid by such Vendor and any liability (including penalties,
interest, additions to tax and expenses, except for, in the event such Vendor or
Administrative Agent fails to deliver notice of such assertion of Taxes or Other
Taxes to Purchaser within one hundred eighty (180) days after it has received
notice of such assertion or imposition of Taxes or Other Taxes, any such
penalties, interest or expenses which would not have arisen but for the failure
of such Vendor or Administrative Agent to so notify Purchaser of such assertion
or imposition of Taxes or Other Taxes) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or



                                      34.
<PAGE>   36

legally asserted. Payment under this indemnification shall be made within thirty
(30) days from the date such Vendor or Administrative Agent makes written demand
therefor.

                    (iii) If Purchaser shall be required by law to deduct or
withhold any Taxes or Other Taxes from or in respect of any sum payable
hereunder to any Vendor or Administrative Agent, then:

                         (A) the sum payable shall be increased as necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under this SECTION 2.14) such Vendor or Administrative
Agent receives an amount equal to the sum it would have received had no such
deductions been made;

                         (B) Purchaser shall make such deductions; and

                         (C) Purchaser shall pay the full amount deducted to the
relevant taxation authority or other authority in accordance with applicable
law.

                    (iv) Within thirty (30) days after the date of payment by
Purchaser of Taxes or Other Taxes, Purchaser shall furnish to Administrative
Agent and each Vendor the original or a certified copy of a receipt evidencing
payment thereof, or other evidence of payment satisfactory to Administrative
Agent.

                    (v) If Purchaser fails to pay any Taxes or Other Taxes when
due to the appropriate taxing authority or fails to furnish to each Vendor the
required receipts or other required documentary evidence, Purchaser shall
indemnify Vendors for any incremental Taxes or Other Taxes, interest or
penalties that may become payable by any of Vendors or Administrative Agent as a
result of any such failure.

                    (vi) If Purchaser is required to pay additional amounts to
any Vendor pursuant to SECTION 2.14(c) hereof, then such Vendor shall use its
reasonable best efforts (consistent with legal and regulatory restrictions) to
change the jurisdiction of its Vendor Office so as to eliminate any such
additional payment by such Vendor which may thereafter accrue if such change in
the judgment of such Vendor is not otherwise materially disadvantageous to such
Vendor.

        2.15 CAPITAL REQUIREMENTS. If after the date hereof any Vendor
determines in good faith that (a) the adoption of or change in any law, rule,
regulation or guideline regarding capital requirements for Vendors, banks or
bank holding companies, or any change in the interpretation or application
thereof by any Governmental Authority charged with the administration thereof;
or (b) compliance by such Vendor or any of its Affiliates with any guideline,
request or directive of any such entity implemented after the date hereof
regarding capital adequacy (whether or not having the force of law), has the
effect of reducing the return on such Vendor's or such Affiliate's capital as a
consequence of such Vendor's commitment to make Forbearances hereunder to a
level below that which such Vendor or such Affiliate could have achieved but for
such adoption, change or compliance (taking into consideration such Vendor's or
such Affiliates' then existing policies with respect to capital adequacy and
assuming the full utilization of such entity's capital) by any amount deemed by
such Vendor to be material, then such Vendor shall notify Purchaser thereof.
Purchaser agrees to pay to such Vendor the amount of such reduction in the
return on capital as and when such reduction is determined, upon presentation by
such



                                      35.
<PAGE>   37

Vendor of a statement in the amount and setting forth such Vendor's calculation
thereof, which statement shall be deemed true and correct absent manifest error.
In determining such amount, such Vendor may use any reasonable averaging and
attribution methods.

        2.16 SYNDICATION. QUALCOMM, Administrative Agent, Collateral Agent and
each Vendor shall have the right from time to time to arrange, or to attempt to
arrange, a syndication of the Forbearances (a "Syndication"); provided that no
more than three (3) full Syndications shall occur per year. Purchaser shall
cooperate with QUALCOMM, Administrative Agent, Collateral Agent and each Vendor
to facilitate any Syndication, and Purchaser agrees, at its expense, to execute
and deliver such documents (including amendments to this Agreement reasonably
requested by QUALCOMM, Administrative Agent or Collateral Agent relating to such
Syndication and which do not impose on Purchaser additional financial
obligations, negative covenants, affirmative covenants, security or credit
support or events of default), furnish such information, attend such meetings,
assist QUALCOMM, Administrative Agent, Collateral Agent and Vendors, and take
any and all other actions as may be reasonably requested by QUALCOMM,
Administrative Agent, Collateral Agent or any Vendor in connection with any
Syndication. QUALCOMM's rights under this SECTION 2.16 shall terminate at such
time as all of the interests of QUALCOMM in any capacity hereunder have been
assigned without recourse.

        2.17 REPLACEMENT OF VENDORS. Upon the occurrence of any event giving
rise to the operation of SECTION 2.14(b), SECTION 2.14(c) or SECTION 2.15 with
respect to any Vendor which results in such Vendor charging to the Purchaser
increased costs in excess of those being charged generally by the Vendors
hereunder or results in such Vendor seeking indemnification for Taxes or Other
Taxes, Purchaser shall have the right, if no Event of Default or Unmatured Event
of Default then exists, to replace such Vendor hereunder (the "Replaced Vendor")
with one or more replacement vendors (collectively, the "Replacement Vendor")
reasonably acceptable to Administrative Agent, provided that (i) at the time of
any replacement pursuant to this SECTION 2.17, the Replacement Vendor shall
enter into one or more Assignment and Acceptance pursuant TO SECTION 9.7 (and
with all fees payable pursuant to said SECTION 9.7 to be paid by the Replacement
Vendor) pursuant to which the Replacement Vendor shall acquire all of the
commitments and outstanding Forbearances of the Replaced Vendor and, in
connection therewith, shall pay to the Replaced Vendor in respect thereof an
amount equal to the sum of (A) an amount equal to the principal of, and all
accrued but unpaid interest on, all outstanding Forbearances of the Replaced
Vendor and (B) an amount equal to all accrued, but unpaid, Commitment Fee owing
to the Replaced Vendor pursuant to SECTION 2.8(b), and (ii) all obligations of
the Purchaser owing to the Replaced Vendor (other than those specifically
described in clause (i) above in respect of which the assignment purchase price
has been, or is concurrently being, paid) shall be paid in full to such Replaced
Vendor concurrently with such replacement. Upon the execution of the respective
Assignment Agreement, the payment of amounts referred to in clauses (i) and (ii)
above and, if so requested by the Replacement Vendor, delivery to the
Replacement Vendor of the appropriate Pagares executed by the Purchaser, the
Replacement Vendor shall become a Vendor hereunder and the Replaced Vendor shall
cease to constitute a Vendor hereunder, except with respect to indemnification
provisions applicable to the Replaced Vendor under this Agreement, which shall
survive as to such Replaced Vendor.

standing under the laws of their respective places of incorporation, have the
power and authority to own their property and carry on their business as now
being conducted, and are qualified as foreign corporations and in good standing

               (b) CORPORATE POWER; AUTHORIZATION. The execution, delivery and
performance by Purchaser and each Guarantor which is or may become a party to
any Credit Document are within their corporate powers, have been duly authorized
by all necessary corporate action, and do not (i) contravene such Person's
Estatutos Sociales, certificate of incorporation or bylaws; (ii) violate any law
or any contractual restriction binding on or affecting such Person, except where
such violation would not be reasonably likely to have a Material Adverse Effect;
or (iii) result in or require the creation of any Lien other than Permitted
Liens, upon or with respect to any of the properties of Purchaser or any
Guarantor.

               (c) APPROVALS. Except for (i) the amendment to the existing

applicable waiting periods relating to any of the foregoing have expired without
any action being taken by any competent Governmental Authority which restrains,
prevents or imposes materially adverse conditions upon the consummation of this
Agreement or the Equipment Agreements.

               (d) ENFORCEABILITY. This Agreement is, and each other Credit
Document to which Purchaser, Parent or any Guarantor is or will be a party when
delivered hereunder will be, legal, valid and binding obligations of such Person
enforceable against it in accordance with their respective terms, provided that

                                      42.
<PAGE>   44

               (e) FINANCIAL STATEMENTS/PROJECTIONS. The consolidated balance
sheet of the Purchaser and each Guarantor as at December 31, 1998, and the
related consolidated statements of income and retained earnings of the Purchaser
and each Guarantor for the fiscal year then ended, copies of which have been
furnished to Vendors, fairly present in all material respects the financial
condition of the Purchaser and each Guarantor on a consolidated basis as at such
date and the results of the operations of the Purchaser and each Guarantor for
the period ended on such date, all in accordance with GAAP consistently applied,
and there has been no material adverse change in such condition or operations or
in the assets, liabilities, properties, business or prospects of Purchaser and
each Guarantor taken as a whole or of any Guarantor or Purchaser individually.
All financial forecasts and projections delivered to Administrative Agent or
Vendors as of the date hereof have been reasonably prepared using the best

               (f) LITIGATION. Except as listed on SCHEDULE 4.1(f) there is no
pending or, to the best knowledge of Purchaser and each Guarantor, threatened,
action, suit, investigation or proceeding against Purchaser or any Guarantor or

governmental department, commission, board, bureau, instrumentality or agency or
arbitrator which might have a Material Adverse Effect.

               (g) COMPLIANCE WITH LAWS, OTHER AGREEMENTS. Except as disclosed
on SCHEDULE 4.1(g), neither Purchaser nor any Guarantor is in violation or
default with respect to their respective certificate of incorporation, bylaws or

be reasonably likely to have a Material Adverse Effect, nor is Purchaser nor any
Guarantor in violation of or in default with respect to any order, writ, decree
or judgment of any court or administrative agency or in violation or default
(nor is there any waiver in effect which, if not in effect, would result in a
violation or default) under any mortgage, indenture, lease, contract or other
agreement or instrument binding upon Purchaser or any such Guarantor, where such
violation or default would be reasonably likely to have a Material Adverse
Effect.

               (h) EVENT OF DEFAULT. No Event of Default or Unmatured Event of
Default has occurred and is continuing.

               (i) COLLATERAL DOCUMENTS. Except for Permitted Liens and Liens
noted in SCHEDULE 4.1(i), the provisions of the Collateral Documents are and
will continue to be effective to create and maintain in favor of Collateral
Agent for the benefit of Vendors a legal, valid and enforceable first priority
perfected security interest in all assets of Purchaser, including, without
limitation, the Pledged Shares. All necessary and appropriate recordings,
registrations and filings have been made in all appropriate public offices, and
all other necessary and appropriate action has been taken so that each
Collateral Document creates an effective Lien with respect to the property,
assets, contract rights and revenues covered thereby to the extent a security
interest may be created therein under applicable laws, prior and superior to all
other Liens except for Permitted Liens, and consents to the creation,
effectiveness, priority and enforcement of such Liens have been obtained from
each of the parties to the Credit Documents and the relevant Governmental
Authorities.

accordance with their respective terms) of the Credit Documents, the Fee Letter,
the Administrative Agent's Fee Letter and the borrowings hereunder and the use
of the proceeds thereof, will not (i) violate any law or regulations; (ii)
contravene, violate or constitute a breach under any corporate document or
contractual obligations of Purchaser or any of its Subsidiaries or any
Guarantor; and (iii) will not result in, or require, the creation or imposition
of any Lien on any of Purchaser's or any Guarantors' properties or revenues or
any properties or revenues of any of Purchaser's Subsidiaries except pursuant to
the express terms of the Credit Documents.

               (l) SUBSIDIARIES. Purchaser and Guarantors do not as of the date

assessments made against it or against any of its property (other than those the
amount or validity of which is 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 Purchaser or Guarantors, as the case may
be) and (ii) all other taxes, fees or other charges imposed on it or imposed on
any of its property by any Governmental Authority (other than those the amount
or validity of which is 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 Purchaser or Guarantors, as the case may be), and no
claims are being asserted with respect to any such taxes, fees or other charges
(other than those the amount or validity of which is 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 Purchaser or Guarantors,
as the case may be). No tax Liens have been filed with respect to any such
taxes, fees or other charges (other than those the amount or validity of which
is 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 Purchaser or Guarantors, as the case may be).

               (n) OWNERSHIP AND LIENS. Subject to the sale of equipment and
services under the Equipment Agreements, Purchaser owns and has good and

<PAGE>   46

SCHEDULE 4.1(i), none of the properties and assets owned by Purchaser and its
Subsidiaries and none of its leasehold interests are subject to any Lien, except

trade credit providing for payment within ninety (90) days of invoice) involving
$100,000 or more in respect of which Purchaser or any Guarantor is in any manner
directly or contingently obligated. The maximum principal or face amounts of the
credits in question, which are outstanding and which can be outstanding, are
correctly stated, and all Liens of any nature given or agreed to be given as
security therefor are correctly described or indicated in such Schedule.

               (p) ACCURACY OF INFORMATION FURNISHED; COMPLETE DISCLOSURE.
Neither this Agreement nor any certificate, data, report, statement or other
information furnished to Vendors by or on behalf of Purchaser or any Guarantor
in connection with the transactions contemplated hereby or by the other Credit
Documents contains or will contain any untrue statement of a material fact or
omits or will omit to state a material fact necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. There is no fact known to Purchaser or any Guarantor which would be
reasonably likely to have a Material Adverse Effect which has not been disclosed
herein or in such other documents, certificates and statements furnished to
Vendors for use in connection with the transaction contemplated hereby.

               (q) NO DEFAULT. Neither Purchaser nor any Guarantor is in default
under or with respect to any Contractual Obligation in any respect which would
be reasonably likely to lead to a Material Adverse Effect.

               (r) NO BURDENSOME RESTRICTIONS. No contractual obligation of
Purchaser or any Guarantor and no Requirement of Law, insofar as Purchaser or
any Guarantor may reasonably foresee, are reasonably likely to result in a
Material Adverse Effect.

               (s) COMPLIANCE WITH PERSONAL COMMUNICATIONS SERVICES REGULATIONS,
LICENSES AND RELATED AGREEMENTS. Purchaser has been awarded a license to provide
broadband fixed and mobile wireless personal communications services
telecommunication services ("License") for Chile and has obtained and currently
maintains (or will maintain) the License and all other required federal, state,
national, provincial and local licenses related to its provision thereof ("Other
Licenses") in such areas, all of which are summarized on SCHEDULE 4.1(s).
Neither Purchaser nor any Guarantor is in violation of any federal, state,
national, provincial or local statute, rule, regulation or order relating to the
licensing of it as a provider of such services including, but not limited to,
any statute in the Republic of Chile relating to its maintenance of the License
and eligibility therefor, including, but not limited to, those statutes, rules,
regulations or orders governing its control, ownership and affiliation by or
with other persons or entities; its ownership by non-citizens; its cross
ownership of cellular services in various geographical service areas; or the
restrictions on the assignment and transfer of control of the License and the
renewal of the License, violation of which might have a Material Adverse Effect.
Neither Purchaser nor any Guarantor is in default of any term of the License or
any Other Licenses, and there exists no agreement with any non-governmental or
third party Person relating to the pledge



                                      45.
<PAGE>   47

by Purchaser or any Guarantor of the License or Other Licenses as collateral
("Third Party Collateral Agreements"). Neither Purchaser nor any Guarantor has
pledged the License or any Other Licenses as collateral under any license
financing agreement, Third Party Collateral Agreement or any other agreement nor
is the License nor any Other Licenses subject to any claim, Lien, security
interest or other encumbrance.

               (t) OTHER REGULATORY COMPLIANCE. Neither Purchaser nor any
Guarantor is an "investment company" or a company "controlled" by an "investment
company" within the meaning of the Investment Company Act of 1940, as amended.
Purchaser and Guarantor are not engaged principally, or as one of the important
activities, in the business of extending credit for the purpose of purchasing or
carrying margin stock (within the meaning of Regulations T and U of the Board of
Governors of the Federal Reserve System). Purchaser and Guarantor have complied
with all the provisions of the Federal Fair Labor Standards Act and the Labor
Code of the Republic of Chile. Purchaser and Guarantor have not violated any
statutes, laws, ordinances or rules applicable to them, violation of which would
be reasonably likely to have a Material Adverse Effect.

               (u) ENVIRONMENTAL CONDITION. None of Purchaser's nor any
Guarantor's properties or assets has ever been used by such Person or their
Affiliates or, to the best of such Person's knowledge, by previous owners or
operators, in the disposal of, or to produce, store, handle, treat, release or
transport, any hazardous waste or hazardous substance other than in accordance
with applicable law; none of Purchaser's or any Guarantor's properties or assets
has ever been designated or identified in any manner pursuant to any
environmental protection statute as a hazardous waste or hazardous substance
disposal site, or a candidate for closure pursuant to any environmental
protection statute; no Lien arising under any environmental protection statute
has attached to any revenues or to any real or personal property owned by
Purchaser or any Guarantor; and Purchaser and Guarantors have never received a
summons, citation, notice or directive from any federal, state, national,
provincial or other Governmental Authority concerning any action or omission by
Purchaser or any Guarantor resulting in the releasing, or otherwise disposing of
hazardous waste or hazardous substances into the environment.

               (v) TRANSACTIONS WITH AFFILIATES. As of the date hereof and as of
the Operative Date, SCHEDULE 4.1(v) sets forth each agreement whereby a
transaction with an aggregate value in excess of $200,000 is contemplated
between any Guarantor or Purchaser and an Affiliate of any of them. Each
transaction (regardless of value) of any Guarantor or Purchaser with an
Affiliate of any of them is on fair and reasonable terms no less favorable to
such Guarantor or Purchaser, as applicable, than would be obtained in a
comparable arm's length transaction with a Person not an Affiliate.

               (w) YEAR 2000. Purchaser reasonably believes that all computer
applications that are material to its business and operations will on a timely
basis be able to perform properly date-sensitive functions for all dates before,
on and after January 1, 2000 (that is, "Year 2000 Compliant"), except to the
extent that a failure to do so would not have a Material Adverse Effect.

               (x) EMPLOYEE BENEFIT PLANS. Neither Purchaser nor any Guarantor
has any employee benefit plans, including retirement plans which have been
established or are



                                      46.
<PAGE>   48

maintained, or to which contributions have been made by or for Purchaser or any
Guarantor. Purchaser and Guarantors are not now and never have been obligated to
contribute to any employee pension benefit plan that is a multi-employer plan
and each is not liable for and is not expected to incur any withdrawal liability
with respect to any multi-employer plan. There are not now, nor have there been,
any medical health-related life insurance or other retiree benefits provided or

SECTION 6. EVENTS OF DEFAULT.

         6.1 EVENTS OF DEFAULT. The occurrence of any one or more of the
following events shall constitute an Event of Default:

                  (a) A failure by Purchaser to pay (whether by scheduled
maturity, required prepayment, by acceleration or otherwise) the following
amounts (i) any principal of any Forbearance when due, or (ii) any interest on
any Forbearance, any other amounts owing hereunder or under any other Credit
Document or any other amounts constituting Obligations within five (5) days
after such interest or other amounts first becomes due; or

                  (b) Any representation or warranty made by Purchaser or any
Guarantor (or any of their officers), under or in connection with this Agreement
or any other Credit Document shall prove to have been incorrect in any material
respect when made or deemed made; or

                  (c) Purchaser, any Subsidiary of Purchaser or any Guarantor
shall fail to perform or observe any other term, covenant or agreement on its
part to be performed or observed and contained in this Agreement or any other
Credit Document and such failure shall not have been remedied within thirty (30)
days after the date on which written notice thereof shall have been received by
Purchaser from Administrative Agent (provided, however, that the breach of
SECTIONS 5.1(C), (H) (N) (O) and (P), and SECTIONS 5.2, 5.3 and 5.4 hereof
shall, immediately upon any such breach, constitute an Event of Default); or





                                      61.
<PAGE>   63

                  (d) Purchaser, any of its material Subsidiaries or any
Guarantor shall fail to pay any of their Material Indebtedness (excluding
Indebtedness incurred under this Agreement) or any interest or premium thereon,
when due (whether by scheduled maturity, required prepayment, acceleration,
demand or otherwise) and such failure shall continue after the applicable grace
period, if any, specified in the agreement or instrument relating to such
Material Indebtedness; or any other default under any agreement or instrument
relating to any such Material Indebtedness, or any other event, shall occur and
shall continue after the applicable grace period, if any, specified in such
agreement or instrument, if the effect of such default or event is to
accelerate, or to permit the acceleration of, the maturity of such Material
Indebtedness; or any such Material Indebtedness shall be declared to be due and
payable, or required to be prepaid (other than by a regularly scheduled required
prepayment or prepayments required by the terms of such Indebtedness upon a sale
of assets) prior to the stated maturity thereof. As used in this SECTION 6.1,
"Material Indebtedness" shall mean (i) during any fiscal quarter of Purchaser
following a fiscal quarter during which Purchaser's EBITDA was less than zero
(0), any Indebtedness with a principal amount in excess of One Million Dollars
($1,000,000) and (ii) in all other cases, any Indebtedness with a principal
amount in excess of Five Million Dollars ($5,000,000); provided, however, that
if an Event of Default does not exist but would exist under this SECTION 6.1(D)
if the threshold set forth in clause (ii) of this sentence were applicable, then
an Event of Default shall arise on the last day of the first fiscal quarter
during which Purchaser's EBITDA was less than zero (0) and such failure or
condition which would give rise to such Event of Default is continuing;

                  (e) Purchaser, any Guarantor or any of their Subsidiaries
shall (i) apply for or consent to the appointment of a receiver, trustee,

property, (ii) be unable, or admit in writing its inability, to pay its debts
generally as they mature, (iii) make a general assignment for the benefit of its
or any of its creditors, (iv) be dissolved or liquidated in full or in part, (v)
become insolvent (as such term may be defined or interpreted under any
applicable statute), (vi) commence a voluntary case or other proceeding seeking
liquidation, reorganization or other relief with respect to itself or its debts
under any bankruptcy, insolvency or other similar law now or hereafter in effect
or consent to any such relief or to the appointment of or taking possession of
its property by any official in an involuntary case or other proceeding
commenced against it, or (vi) take any action for the purpose of effecting any
of the foregoing; or

                  (f) Proceedings for the appointment of a receiver, trustee,
liquidator or custodian of Purchaser, any Guarantor or any of their Subsidiaries
or of all or a substantial part of any of their respective property, or an
involuntary case or other proceedings seeking liquidation, reorganization or
other relief with respect to Purchaser, any Guarantor or any of their
Subsidiaries, under any bankruptcy, insolvency or other similar law now or
hereafter in effect shall be commenced and an order for relief entered or such
proceeding shall not be dismissed or discharged within forty five (45) days of
commencement; or

                  (g) There occurs, in relation to Purchaser, any Guarantor or
any of their Subsidiaries, in any country or territory in which they carry on
business or to the jurisdiction of whose courts any part of their assets are
subject, any event which in that country or territory corresponds with, or has
an effect equivalent or similar to, any of those mentioned in SECTION 6.1(E) or
SECTION 6.1(F) (subject to the cure period stated therein); or





                                      62.
<PAGE>   64

                  (h) Purchaser, any of its Subsidiaries or any Guarantor shall
fail to pay and discharge any judgment or order, or levy of any attachment,
execution or other process against its assets and such judgment, order, levy or
other process shall remain undischarged, unvacated, unbonded or unstayed for a
period of forty five (45) days or in any event five (5) days prior to the time
of any proposed sale under any such judgment or levy; or

                  (i) If any of the Equipment Agreements or the Other Project
Documents, including, without limitation, the Security Agreements, shall for any
reason be unenforceable or cease to be in full force and effect or shall cease
to give Secured Parties the Liens, rights, powers and privileges purported to be
created thereby (including, without limitation, a first priority perfected
security interest in, and Lien on, all of the collateral subject thereto) in
favor of Secured Parties, superior to and prior to the rights of all third
Persons and subject to no other Liens (except to the extent expressly permitted
herein or therein), or any Guarantor, Purchaser or any of their Subsidiaries
shall fail to perform or observe any term, covenant, condition, agreement or
obligation on its part to be performed or observed pursuant thereto or any
Guarantor, Purchaser or any of their Subsidiaries party to any of such foregoing
documents shall deny or disaffirm such Person's obligations thereunder; or

                  (j) Purchaser shall abandon the development, ownership or
operation of the Project or shall suspend all or part of its business operations
material to the conduct of Purchaser's business, which abandonment and
suspension shall be material to the operation of the System as a whole; or

                  (k) There shall have occurred any act or series of acts
attributable to a Governmental Authority which (i) has the effect of depriving
Vendors of any rights (the loss of which would not be de minimis) as creditors
in respect of this Agreement or any other Credit Document, or (ii) attempts to
condemn, confiscate, seize, nationalize or expropriate the ownership or control
of all or any substantial part of the assets of Purchaser or any Governmental
Authority shall require a material modification or revocation of the License or
Other Licenses, and which condemnation, confiscation, seizure, nationalization
or expropriation shall be material to the operation of the System as a whole; or

                  (l) Any law, order, decree or regulation shall impose any
restriction on (i) the lawful transfer of Dollars by Purchaser from the Republic
of Chile to Administrative Agent (and from Administrative Agent to any other
Person or locale whether within or outside of the Republic of Chile), (ii) the
conversion of (A) Dollars to Pesos or (B) Pesos to Dollars, or (iii) the
purchase of Dollars in the formal foreign exchange market of the Republic of
Chile to pay the Forbearances, which restriction might have an adverse effect on
the ability of Purchaser to pay the Forbearances as scheduled or upon an
acceleration after an Event of Default; or

                  (m) An event shall have occurred which would be reasonably
likely to result in a Material Adverse Effect.

         6.2 REMEDIES. Immediately and without notice upon the occurrence of an
Event of Default specified in SECTION 6.1(E), 6.1(F) or 6.1(G) of this
Agreement, or, at the option of Requisite Vendors, upon the occurrence of any
other Event of Default, (a) all amounts and obligations owed to Administrative
Agent, Collateral Agent and Vendors pursuant to this Agreement, the Notes,
Pagares and the other Credit Documents shall immediately become due



                                      63.
<PAGE>   65

and payable (including without limitation any unpaid Commitment Fee); (b) the
obligation of Vendors to make any Forbearance under this Agreement or the other
Credit Documents and all commitments hereunder shall be terminated, all without
presentment, demand, protest or notice of any kind, all of which are hereby
expressly waived; and (c) without the expiration of any other period of grace,
Administrative Agent, Collateral Agent or any Vendor may immediately enforce
payment of the amounts owed it hereunder and exercise any and all other rights
and remedies granted to it by this Agreement or any of the other Credit
Documents or at law, in equity or otherwise.

         6.3 UNMATURED EVENTS OF DEFAULT. Upon the occurrence of any Unmatured
Event of Default, the obligation of Vendors to make any Forbearances under this
Agreement or the other Credit Documents shall be suspended until such event is
either waived by Requisite Vendors or, to the extent allowed hereunder, cured.

SECTION 7. ADMINISTRATIVE AGENT.

         7.1 APPOINTMENT of QUALCOMM INCORPORATED as ADMINISTRATIVE AGENT.
Vendors hereby designate and appoint QUALCOMM Incorporated as Administrative
Agent to act in an administrative function as specified under this Agreement and
the other Credit Documents and irrevocably authorizes Administrative Agent to
take such actions on its behalf under and subject to the provisions of this
Agreement and each other Credit Document and to exercise such powers and perform
such duties as are expressly delegated to it by the terms of this Agreement or
any other Credit Document, together with such other powers, in the judgment of
Administrative Agent, as are reasonably incidental thereto. Notwithstanding any
provision to the contrary elsewhere in this Agreement or any other Credit
Document, Administrative Agent shall not have any duties or responsibilities,
except those expressly set forth herein or therein, or any fiduciary
relationship with any Vendor, 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 Administrative
Agent.

         7.2 RIGHTS AND POWERS AS VENDOR. The bank serving as Administrative
Agent hereunder shall have the same rights and powers in its capacity as a
Vendor as any other Vendor and may exercise the same as though it were not
Administrative Agent, and such bank and its Affiliates may accept deposits from,
lend money to, act as trustee under indentures of, and generally engage in any
kind of business with, Purchaser or any Subsidiary or other Affiliate of any
such Person and any Person who may do business with or own securities of
Purchaser or any such Subsidiary or Affiliate, all as if such bank were not
Administrative Agent and without any duty to account therefor to the Vendors or
any other Person.

         7.3 DELEGATION OF DUTIES BY ADMINISTRATIVE AGENT. Administrative Agent
may execute any of its duties under this Agreement by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. Administrative Agent shall not
be responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects with reasonable care.

         7.4 LIABILITY OF ADMINISTRATIVE AGENT. None of Administrative
Agent-Related Persons (defined below) shall (a) be liable for any action taken
or omitted to be taken by any of them under or in connection with this Agreement
or any other Credit Document (except for its




                                      64.
<PAGE>   66

own gross negligence or willful misconduct), or (b) be responsible in any manner
to any of the Vendors for any recital, statement, representation or warranty
made by Purchaser or any Affiliate of Purchaser, or any officer thereof,
contained in this Agreement or in any other Credit Document, or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Administrative Agent under or in connection with, this
Agreement or any other Credit Document, or for the value of any Collateral or
the validity, priority, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any Credit Document, or for any failure of
Purchaser or any other party to any Credit Document to perform its obligations
hereunder or thereunder. No Administrative Agent-Related Person shall be under
any obligation to any Vendor 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 Purchaser or any of Purchaser's Affiliates. "Administrative
Agent-Related Persons" shall mean Administrative Agent and any successor
Administrative Agent, together with their respective Affiliates, and the
employees, agents and attorneys-in-fact of such persons.

         7.5  RELIANCE BY ADMINISTRATIVE AGENT.

                  (a) Administrative Agent shall be entitled to rely, and shall
be fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement 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 counsel to
Purchaser), independent accountants and other experts selected by Administrative
Agent. Administrative Agent 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 Requisite Vendors as it deems
appropriate and indemnification for all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action,
provided, however, that Administrative Agent shall be justified in refusing to
take action if such action is in violation of law or the terms of this Agreement
or any other Credit Document, based on the advise of Administrative Agent's
legal counsel. Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement or any other Credit
Document in accordance with a request or consent of Requisite Vendors and such
request and any action taken or failure to act pursuant thereto shall be binding
upon all of Vendors.

                  (b) For purposes of determining compliance with the conditions
precedent specified in SECTION 3, each Vendor that has executed this Agreement
or shall hereafter execute and deliver an Assignment and Acceptance in
accordance with SECTION 9.7 shall be deemed to have consented to, approved or
accepted or to be satisfied with each document or other matter either sent by
Administrative Agent to such Vendor for consent, approval, acceptance or
satisfaction, or required thereunder to be consented to or approved by or
acceptable or satisfactory to such Vendor, unless an officer of Administrative
Agent responsible for the transactions contemplated by the Credit Documents
shall have received notice from such Vendor prior to the initial borrowing
specifying its objection thereto and either such objection shall not have been
withdrawn by notice to Administrative Agent to that effect or such Vendor shall
not have made available to Administrative Agent its ratable portion of such
borrowing





                                      65.
<PAGE>   67

         7.6 NOTICE OF DEFAULT. Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of any Event of Default, except with
respect to defaults in the payment of principal, interest and fees required to
be paid to Administrative Agent on behalf and for the benefit of Vendors, unless
Administrative Agent shall have received written notice from a Vendor or
Purchaser referring to this Agreement, describing such Event of Default and
stating that such notice is a "notice of default." In the event that
Administrative Agent receives such a notice, Administrative Agent shall give
notice thereof to each Vendor. Administrative Agent shall take such action with
respect to such Event of Default as shall be requested by Requisite Vendors in
accordance with SECTION 6; provided, however, that unless and until
Administrative Agent shall have received any such request, Administrative Agent
may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Event of Default as it shall deem in the best
interest of Vendors.

         7.7 NON-RELIANCE BY VENDORS. Each Vendor expressly acknowledges that
none of Administrative Agent-Related Persons has made any representation or
warranty to it and that no act by Administrative Agent hereafter taken,
including any review of the affairs of Purchaser or Guarantors, shall be deemed
to constitute any representation or warranty by Administrative Agent to such
Vendor. Each Vendor confirms to Administrative Agent that it has not relied, and
will not rely hereafter, on Administrative Agent to check or inquire on such
Vendor's behalf into the adequacy, accuracy or completeness of any information
provided by Purchaser or Guarantors or any other Person under or in connection
with the Credit Documents or the transactions herein contemplated (whether or
not the information has been or is hereafter distributed to such Vendor by
Administrative Agent). Each Vendor represents to Administrative Agent that it
has, independently and without reliance upon Administrative Agent and based on
such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, prospects, operations,
Property, financial and other condition and creditworthiness of Purchaser or
Guarantors, and all applicable regulatory laws relating to the transactions
contemplated thereby, and made its own decision to enter into this Agreement and
the other Credit Documents and extend credit to Purchaser under and pursuant to
this Agreement. Each Vendor also represents that it will, independently and
without reliance upon Administrative Agent and based on such documents and
appraisals and decisions in taking or not taking action under this Agreement and
the other Credit Documents, and to make such investigations as it deems
necessary to inform itself as to the business, prospects, operations, property,
financial and other condition and creditworthiness of Purchaser or Guarantors.
Except for notices, reports and other documents expressly herein required to be
furnished to Vendors by Administrative Agent, Administrative Agent shall not
have any duty or responsibility to provide to any Vendor any credit or other
information concerning the business, prospects, operations, property, financial
and other condition or creditworthiness of Purchaser or Guarantors which may
come into the possession of any Administrative Agent-Related Persons.
Administrative Agent shall not be responsible to any Vendor for the execution,
effectiveness, priority, genuineness, validity, enforceability, collectibility
or sufficiency of this Agreement the Credit Documents or for any representations
or warranties, recitals or statements made herein or therein or made in any
written or oral statements, or in any financial or other statements,
instruments, reports or certificates or any other documents furnished or made
available by Administrative Agent to Vendors or by or on behalf of Purchaser or
Guarantors to Administrative Agent or any Vendor in connection with the Credit
Documents or the transactions contemplated thereby or for the financial
condition or business affairs of Purchaser or Guarantors or any Person liable
for payment of the Obligations, nor shall Administrative Agent be required to
ascertain or inquire as



                                      66.
<PAGE>   68

to the performance or observance of any of the terms, conditions, provisions,
covenants or agreements contained in any of the Credit Documents or as to the
use of proceeds of the Forbearances or as to the existence or possible existence
of any Event of Default.

         7.8 INDEMNIFICATION. Whether or not the transactions contemplated
hereby are consummated, Vendors shall indemnify upon demand Administrative
Agent-Related Persons (to the extent not reimbursed by or on behalf of Purchaser
and without limiting the obligation of Purchaser to do so) ratably from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses and disbursements of any kind
whatsoever which may at any time (including at any time following the repayment
of the Forbearances or the termination or the resignation of the related
Administrative Agent) be imposed on, incurred by or asserted against any such
Person in any way relating to or arising out of this Agreement or any of the
other Credit Documents or the transactions contemplated hereby or thereby or any
action taken or omitted by any such Person under or in connection with any of
the foregoing; provided, however, that no Vendor shall be liable for the payment
to Administrative Agent-Related Persons of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from such Person's gross negligence or
willful misconduct. Without limitation of the foregoing, each Vendor shall
reimburse Administrative Agent upon demand for its ratable share of any costs or
other out-of-pocket expenses (including reasonable attorneys' expenses and
disbursements) incurred by Administrative Agent in connection with the
preparation, execution, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement or any
other Credit Document to the extent that Administrative Agent has not previously
been reimbursed for such expenses by or on behalf of Purchaser. Without limiting
the generality of the foregoing, if any tax authority or the Administrative
Agent did not properly withhold tax from amounts paid to or for the account of
any Vendor (because the appropriate form was not delivered, was not properly
executed, or because such Vendor failed to notify Administrative Agent of a
change in circumstances which rendered the exemption from, or reduction of,
withholding tax ineffective, or for any other reason), such Vendor shall
indemnify Administrative Agent fully for all amounts paid, directly or
indirectly, by Administrative Agent as tax or otherwise, including penalties and
interest, and including any taxes imposed by any jurisdiction on the amounts
payable to Administrative Agent under this SECTION 7.8, together with all costs
and expenses (including reasonable attorneys' expenses and disbursements). The
obligations of Vendors in this SECTION 7.8 shall survive the repayment of all
Obligations and the termination of the Credit Documents.

         7.9 SUCCESSOR ADMINISTRATIVE AGENT. Administrative Agent may, and at
the request of Requisite Vendors shall, resign as Administrative Agent upon 30
days' notice to Vendors. If Administrative Agent shall resign as Administrative
Agent under this Agreement and the other Credit Documents, then Requisite
Vendors shall appoint a successor Administrative Agent; provided, however, that
such successor shall also be an Eligible Assignee. If no successor
Administrative Agent is appointed prior to the effective date of the resignation
of Administrative Agent, Administrative Agent may appoint, after consulting with
Vendors and Purchaser, a successor Administrative Agent from among Vendors. Upon
the acceptance of its appointment as successor Administrative Agent hereunder
and under the other Credit Documents, such successor Administrative Agent shall
succeed to the rights, powers and duties of Administrative Agent, the term
"Administrative Agent" shall mean such successor Administrative Agent effective
upon its appointment, and the former Administrative Agent's appointment, rights,



                                      67.
<PAGE>   69

powers and duties as Administrative Agent shall be terminated. After any
retiring Administrative Agent's resignation as Administrative Agent, the
provisions of this SECTION 7 and SECTIONS 9.4 and 9.15 shall continue to inure
to its benefit as to actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement and the other Credit Documents.

SECTION 8. COLLATERAL AGENT.

         8.1 APPOINTMENT OF QUALCOMM INCORPORATED AS COLLATERAL AGENT. Vendors
hereby designate and appoint QUALCOMM Incorporated as Collateral Agent to act as
specified under this Agreement and the other Credit Documents, including,
without limitation, holding all possessory Collateral. Each Vendor hereby
irrevocably authorizes, and each holder of a Note and Pagare by the acceptance
of such Note and Pagare shall be deemed to have authorized, Collateral Agent 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 Collateral Agent by the terms of this Agreement or
any other Credit Document, together with such other powers as are reasonably
incidental hereto and thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement or any other Credit Document, Collateral Agent shall
not have any duties or responsibilities, except those expressly set forth herein
or therein, or any fiduciary relationship with any Vendor, 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 Collateral Agent.

         8.2 DELEGATION OF DUTIES BY COLLATERAL AGENT. Collateral Agent may
execute any of its duties under this Agreement or any of the Credit Documents by
or through agents, employees or attorneys-in-fact, including, without
limitation, any local agent appointed by Collateral Agent in relation to
registering the security interest of Secured Parties under any of the Collateral
Documents, and shall be entitled to advice of counsel concerning all matters
pertaining to such duties. Collateral Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact, including, without
limitation, any such local agent, that it selects with reasonable care.

         8.3 LIABILITY OF COLLATERAL AGENT. None of Collateral Agent-Related
Persons (as defined below) shall (a) be liable for any action taken or omitted
to be taken by any of them under or in connection with this Agreement (except
for its own gross negligence or willful misconduct), or (b) be responsible in
any manner for the value of any Collateral or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any Credit
Document. No Collateral Agent-Related Person shall be under any obligation to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement, or to inspect the
properties, books or records of Purchaser. "Collateral Agent-Related Persons"
shall mean Collateral Agent and any successor Collateral Agent, together with
their respective Affiliates, and the employees, agents and attorneys-in-fact of
such persons.

         8.4 RELIANCE BY COLLATERAL AGENT. Collateral Agent shall be entitled to
rely, and shall be fully protected in relying, upon any writing, resolution,
notice, consent, certificate, affidavit, letter, telegram, facsimile, telex or
telephone message, statement or other document or conversation believed by it to
be genuine and correct and to have been signed, sent or made by



                                      68.
<PAGE>   70

the proper Person or Persons, and upon advice and statements of legal counsel
(including counsel to Purchaser), independent accountants and other experts
selected by Collateral Agent.

         8.5 NON-RELIANCE BY VENDORS. Each Vendor expressly acknowledges that
none of Collateral Agent-Related Persons has made any representation or warranty
to it and that no act by Collateral Agent hereafter taken shall be deemed to
constitute any representation or warranty by Collateral Agent to such Vendor.
Collateral Agent shall not have any duty or responsibility to provide to any
Vendor any credit or other information concerning the business, prospects,
operations, property, financial and other condition or creditworthiness of
Purchaser or Guarantor which may come into the possession of any Collateral
Agent-Related Persons. Collateral Agent shall not be responsible to any Vendor
for the execution, effectiveness, genuineness, validity, enforceability,
collectibility or sufficiency of this Agreement or for any representations or
warranties, recitals or statements made herein or made in any written or oral
statements, or in any financial or other statements, instruments, reports or
certificates or any other documents furnished or made by Collateral Agent to
Vendors or by or on behalf of Purchaser or Guarantors to Collateral Agent or any
Vendor in connection with the Credit Documents or the transactions contemplated
thereby or for the financial condition or business affairs of Purchaser or
Guarantors or any Person liable for payment of the Obligations, nor shall
Collateral Agent be required to ascertain or inquire as to the performance or
observance of any of the terms, conditions, provisions, covenants or agreements
contained in any of the Credit Documents or as to the use of proceeds of the
Forbearances or as to the existence or possible existence of any Event of
Default or Unmatured Event of Default.

         8.6 INDEMNIFICATION. Whether or not the transactions contemplated
hereby are consummated, Vendors shall indemnify upon demand Collateral
Agent-Related Persons (to the extent not reimbursed by or on behalf of Purchaser
and without limiting the obligation of Purchaser to do so) ratably from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses and disbursements of any kind
whatsoever which may at any time (including at any time following the repayment
of the Forbearances or the termination or the resignation of the related
Collateral Agent) be imposed on, incurred by or asserted against any such Person
in any way relating to or arising out of this Agreement or any of the other
Credit Documents or the transactions contemplated hereby or thereby or any
action taken or omitted by any such Person under or in connection with any of
the foregoing; provided, however, that no Vendor shall be liable for the payment
to Collateral Agent-Related Persons of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from such Person's gross negligence or
willful misconduct. Without limitation of the foregoing, each Vendor shall
reimburse Collateral Agent upon demand for its ratable share of any costs or
other out-of-pocket expenses (including reasonable attorneys' expenses and
disbursements) incurred by Collateral Agent in connection with the preparation,
execution, administration, modification, amendment or enforcement (whether
through negotiations, legal proceedings or otherwise) of, or legal advice in
respect of rights or responsibilities under, this Agreement or any other Credit
Document to the extent that Collateral Agent has not previously been reimbursed
for such expenses by or on behalf of Purchaser. The obligations of Vendors in
this SECTION 8.6 shall survive the repayment of all Obligations.

         8.7 SUCCESSOR COLLATERAL AGENT. Collateral Agent may resign as
Collateral Agent upon sixty (60) days' notice to Vendors. If Collateral Agent
shall resign as Collateral Agent




                                      69.
<PAGE>   71

under this Agreement and the other Credit Documents, then Requisite Vendors
shall appoint a successor Collateral Agent; provided, however, that such
successor shall also be an Eligible Assignee. No resignation shall be effective
until acceptance of the appointment of a successor Collateral Agent. Such
successor collateral agent shall succeed to the rights, powers and duties of
Collateral Agent, and the term "Collateral Agent" shall mean such successor
collateral agent effective upon its appointment, and the former Collateral
Agent's rights, powers and duties as Collateral Agent shall be terminated,
without any other or further act or deed on the part of such former Collateral
Agent or any of the parties to this Agreement or any holders of the Notes or
Pagares. After any retiring Collateral Agent's resignation as Collateral Agent,
the provisions of this SECTION 8 shall inure to its benefit as to actions taken
or omitted to be taken by it while it was Collateral Agent under this Agreement
and the other Credit Documents.

SECTION 9. MISCELLANEOUS.

         9.1 AMENDMENTS. No amendment or waiver of any provision of this
Agreement or any of the other Credit Documents, nor consent to any departure by
Purchaser therefrom, shall in any event be effective unless the same shall be in
writing and signed by Requisite Vendors and acknowledged by Administrative Agent
and then such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given; provided, however, that no such
amendment or waiver or consent shall, unless in writing and signed by all
Vendors (other than any Vendor which is in default of its obligations hereunder)
and Purchaser and acknowledged by the Administrative Agent, do any of the
following:

                  (a) postpone or delay any date fixed by this Agreement or any
other Credit Document for any payment or prepayment of amounts due to Vendors,
or any of them, hereunder or under any other Credit Document;

                  (b) reduce the amount of any amounts payable to Vendors, or
any of them, hereunder or under any other Credit Document;

                  (c) change the percentage of the Aggregate Commitment or the
aggregate unpaid principal amount of the Forbearances, which is required for
Vendors to take any action hereunder;

                  (d) release all or any substantial part of the collateral
granted or pledged under any of the Collateral Documents, except as otherwise
may be provided in the Collateral Documents;

                  (e) amend, terminate or release the Guaranty; or

                  (f) amend this SECTION 9.1 or any provision herein expressly
providing for consent or other action by all Vendors;

provided further, that no amendment or waiver shall, unless in writing and
signed by Administrative Agent and Collateral Agent in addition to Requisite
Vendors or all Vendors, affect the rights or duties of Administrative Agent and
Collateral Agent under this Agreement or any other Credit Document.





                                      70.
<PAGE>   72

         9.2 NOTICES, ETC. Except as to those notices and other communications
which are expressly authorized to be sent telephonically, all notices and other
communications provided for hereunder shall be in writing (including facsimile
communication) and sent by overnight courier service, telecopied or delivered,
and addressed to Purchaser, Administrative Agent, Collateral Agent or any Vendor
at the address set forth on the signature page hereto, or at such other address
as it may, by written notice received by the other parties to this Agreement,
have designated as its address for such purposes. Administrative Agent,
Collateral Agent, any Vendor or the holder of the Notes and Pagares giving any
waiver, consent or notice to, or making any request upon, Purchaser hereunder
shall promptly notify the other parties to this Agreement at the addresses set
forth as the address of each Person on the signature pages of this Agreement or
at such other address as shall be designated by any party in a written notice to
the other parties hereto.

         The address for notices for Persons which subsequently become Vendors
hereunder shall be as noted in the assignment and acceptance documentation to
which such Person becomes a party. Except as set forth below, all such notices
and communications shall, when mailed by overnight courier service or
telecopied, be effective, if deposited with the overnight courier service, two
(2) Business Days after deposit therewith, or if telecopied, upon being

addressed as aforesaid; provided, however, that notices to Vendors or
Administrative Agent pursuant to the provisions of SECTION 2 of this Agreement
shall not be effective, as of a given Business Day, unless actually received by
Vendors or Administrative Agent or both, as applicable, prior to 1:00 p.m. New
York time, on said Business Day. Notices given to Vendors or Administrative
Agent pursuant to the provisions of SECTION 2 of this Agreement which are
received after 1:00 p.m. New York time on a Business Day shall be considered
effective as of the next succeeding Business Day. Each of such notices specified
in SECTION 2 of this Agreement shall be given by telephone, facsimile or
delivery of such notice. Neither Vendors nor Administrative Agent shall incur
any liability to Purchaser in acting upon any telephone or facsimile notice
referred to in SECTION 2 of this Agreement which Vendors or Administrative Agent
believe in good faith to have been given by a duly authorized officer or other
person authorized to borrow on behalf of Purchaser. Each such telephonic or
facsimile notice shall be irrevocable and binding on Purchaser.

         9.3 NO WAIVER; REMEDIES. No failure on the part of Administrative
Agent, Collateral Agent and Vendors to exercise, and no delay in exercising, any
right under any Credit Document shall operate as a waiver thereof; nor shall any
single or partial exercise of any right under any Credit Document preclude any
other or further exercise thereof or the exercise of any other right. The
remedies provided in the Credit Documents are cumulative and not exclusive of
any remedies provided by law.

         9.4 COSTS, EXPENSES AND TAXES. Purchaser agrees to pay Administrative
Agent or Vendors, as the case may be, on demand, whether or not any Forbearance
is made hereunder, (a) all reasonable fees, costs and expenses incurred by
Administrative Agent, Collateral Agent or Vendors in connection with the
negotiation, preparation, execution, delivery and consummation of, and the
making of the initial Forbearances under, this Agreement and the other Credit
Documents, including, without limitation, the reasonable fees and out-of-pocket
expenses of counsel for Administrative Agent, Collateral Agent and Vendors with
respect thereto and appraisal fees; provided, however that any out of pocket
expenses exceeding Ten Thousand Dollars ($10,000) shall be pre-approved by
Purchaser; (b) all reasonable fees and expenses,



                                       71.
<PAGE>   73

including attorneys' fees, incurred by Administrative Agent, Collateral Agent
and Vendors in connection with the negotiation of and/or the preparation of
amendments to and waivers under the Credit Documents; (c) all reasonable costs
and expenses, if any (including reasonable counsel fees and expenses), incurred
by Administrative Agent, Collateral Agent and Vendors in connection with the
enforcement and administration of the Credit Documents and the other documents
to be delivered under the Credit Documents; and (d) any and all recording and
filing fees and any present and future stamp, excise and other similar taxes
with respect to the foregoing matters, and Purchaser agrees to indemnify and
hold Administrative Agent, Collateral Agent and Vendors harmless from and
against any and all liabilities with respect to or resulting from any delay or
omission to pay Vendors any such taxes. As used herein, "attorneys' fees" shall
include, without limitation, allocable costs of Administrative Agent's,
Collateral Agent's and Vendors' in-house legal counsel and staff.

         9.5 RIGHT OF SET-OFF. Upon the occurrence and during the continuance of
any Event of Default, Administrative Agent, Collateral Agent and Vendors are
hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held and other indebtedness at
any time owing by Vendors to or for the credit or the account of Purchaser or
Guarantors against any and all of the obligations of Purchaser or Guarantors now
or hereafter existing under any Credit Document, irrespective of whether or not
Administrative Agent, Collateral Agent or Vendors shall have made any demand
under such Credit Document and although such obligations may be unmatured.
Vendors agree promptly to notify Purchaser or Guarantors, as the case may be,
after any such set-off and application, provided that the failure to give such
notice shall not affect the validity of such set-off and application. The rights
of Vendors under this Section are in addition to other rights and remedies
(including, without limitation, other rights of set-off) which Vendors may have.

         9.6 RATABLE SHARING. Vendors hereby agree among themselves that if any
of them shall, whether by voluntary payment (other than a voluntary prepayment
of Forbearances made and applied in accordance with the terms of this
Agreement), by realization upon security, through the exercise of any right of
set-off or banker's lien, by counterclaim or cross action or by the enforcement
of any right under the Credit Documents or otherwise, or as adequate protection
of a deposit treated as cash collateral under bankruptcy laws, receive payment
or reduction of a proportion of the aggregate amount of principal, interest,
fees and other amounts then due and owing to that Vendor hereunder or under the
other Credit Documents (collectively, the "Aggregate Amounts Due" to such
Vendor) which is greater than the proportion received by any other Vendor in
respect of the Aggregate Amounts Due to such other Vendor, then the Vendor
receiving such proportionately greater payment shall (i) notify Administrative
Agent and each other Vendor of the receipt of such payment and (ii) apply a
portion of such payment to purchase participations (which it shall be deemed to
have purchased from cash seller of a participation simultaneously upon the
receipt by such seller of its portion of such payment) in the Aggregate Amounts
Due to the other Vendors so that all such recoveries of Aggregate Amounts Due
shall be shared by all Vendors in proportion to the Aggregate Amounts Due to
them; provided that if all or part of such proportionately greater payment
received by such purchasing Vendor is thereafter recovered from such Vendor upon
the bankruptcy or reorganization of Purchaser or otherwise, those purchases
shall be rescinded and the purchase prices paid for such participations shall be
returned to such purchasing Vendor ratably to the extent of such recovery, but
without interest. Purchaser expressly consents to the foregoing arrangement and
agrees that any holder



                                       72.
<PAGE>   74

of a participation so purchased may exercise any and all rights of banker's
lien, set-off or counterclaim with respect to any and all monies owing by
Purchaser to that holder with respect thereto as fully as if the holder were
owed the amount of the participation held by that holder. Each Vendor hereby
agrees that, solely for purposes of this SECTION 9.6, a participant shall be
considered to be a Vendor.

         9.7 BINDING EFFECT; ASSIGNMENTS. This Agreement and the other Credit
Documents shall be binding upon and inure to the benefit of Purchaser, Vendors,
Collateral Agent and Administrative Agent and their respective successors and
assigns. Purchaser and Parent shall not have the right to assign their rights or
delegate their duties hereunder or any interest herein without the prior written
consent of Vendors and Administrative Agent. Vendors may assign or sell
participation interests in all or any part of their interests under this
Agreement or any of the other Credit Documents to any Eligible Assignee.
Purchaser hereby grants its unconditional authorization to Vendors to execute
any such assignment, and agrees that it shall be sufficient that there exist
only an agreement between Vendors and their assignees. Administrative Agent
shall notify Purchaser of the assignment in writing, pursuant to the provisions
of SECTION 9.2. This unconditional acceptance by Purchaser of any such
assignment by Vendors includes Purchaser's and Guarantor's express consent to
the total or partial assignment of the Guaranty or any other guaranties that
have been or may be in the future be extended as surety for the payment and
performance of Purchaser's Obligations under this Agreement and the other Credit
Agreements. Purchaser, Guarantor and Vendors hereby agree that in the event of
any such assignment, the rights and interests in and to the Purchaser's and
Guarantor's payment and performance of its Obligations under this Agreement and
each of the other Credit Agreements, shall be assigned in favor of the one or
several assignees, to be shared jointly with Vendors or such other assignees if
the assignment is in part. Vendors may, subject to SECTION 9.21 below, disclose
the Credit Documents and any financial or other information relating to
Purchaser to any potential assignee or participant. Any Taxes arising from the
assignment shall be borne by Purchaser. The form of Assignment and Acceptance is
attached hereto as EXHIBIT F.

         9.8 COLLATERAL. The obligations of Purchaser under this Agreement are
secured by the Collateral Documents.

         9.9 NATURE OF VENDORS' OBLIGATIONS. Nothing contained in this
Agreement, any other Credit Document or the Equipment Agreements and no action
taken by Vendors pursuant hereto or thereto may, or may be deemed to, make
Administrative Agent, Collateral Agent or Vendors a partnership, an association,
a joint venture, or other entity, with Purchaser.

         9.10 NON-LIABILITY OF VENDORS. The relationship between Purchaser and
Vendors is, and shall at all times remain, solely that of borrower and lender,
and Vendors neither undertake nor assume any responsibility or duty to Purchaser
to review, inspect, supervise, pass judgment upon, or inform Purchaser of any
matter in connection with any phase of Purchaser's business, operations, or
condition, financial or otherwise. Purchaser shall rely entirely upon its own
judgment with respect to such matters, and any review, inspection, supervision,
exercise of judgment, or information supplied to Purchaser by Vendors in
connection with any such matter is for the protection of Vendors, and neither
Purchaser nor any third party is entitled to rely thereon.

         9.11 GOVERNING LAW, JURISDICTION, VENUE, SERVICE OF PROCESS, WAIVER OF
IMMUNITY.

                  (a) GOVERNING LAW, JURISDICTION. This Agreement shall be
governed by, and construed in accordance with, the law of the State of New York,
United States, without reference to principles of conflicts of law (other than
Section 5-1401 of the General Obligations Laws of the State of New York).

                  (b) VENUE. Purchaser, each Guarantor, each Vendor,
Administrative Agent and Collateral Agent hereby agree that any suit, action or
proceeding with respect to this Agreement or any of the other Credit Agreements
or any judgment entered by any court in respect thereof may be brought in the
United States of America District Court for the Southern District of New York,
in the Supreme Court of the State of New York sitting in New York County
(including its Appellate Division), or in any other appellate court in the State
of New York or the courts sitting in the Comuna of Santiago, Santiago, Republic
of Chile, as the party commencing such suit, action or proceeding may elect in
its sole discretion; and Purchaser, each Guarantor, each Vendor, Administrative
Agent and Collateral Agent hereby irrevocably submit to the jurisdiction of such
courts for the purpose of any such suit, action, proceeding or judgment.
Purchaser, each Guarantor, each Vendor, Administrative Agent and Collateral
Agent further submits, for the purpose of any such suit, action, proceeding or
judgment brought or rendered against it, to the appropriate courts of the
jurisdiction of its domicile. Purchaser and Guarantor hereby waive any rights to
a specific jurisdiction it may have by virtue of its present or any future
domicile, or otherwise.

                  (c) SERVICE OF PROCESS. Purchaser and Guarantors hereby agree
that service of all writs, process and summonses in any such suit, action or
proceeding brought (i) in the State of New York may be made upon CT Corporation
System, presently located at 1633 Broadway, New York, New York 10019, U.S.A. and

agree that the Process Agents have been duly and irrevocably appointed as their
respective agent and true and lawful attorney-in-fact in their respective name,
place and stead to accept such service of any and all such writs, process and
summonses, and agree that the failure of the Process Agents to give any notice
of any such service of process to Purchaser or Guarantors, as the case may be,
shall not impair or affect the validity of such service or of any judgment based
thereon. Purchaser and Guarantors hereby further irrevocably consent to the
service of process in any suit, action or proceeding in said courts by the
mailing thereof by Vendor by registered or certified mail, postage prepaid, at
its address set forth beneath its signature hereto. Nothing herein shall in any
way be deemed to limit the ability of Vendors to serve any such writs, process
or summonses in any other manner permitted by applicable law or to obtain
jurisdiction over Purchaser and Guarantors in such other jurisdictions, and in
such manner, as may be permitted by applicable law. Purchaser and Guarantors
hereby irrevocably waive any objection that they may now or hereafter have to
the laying of the venue of any suit, action or proceeding arising out of or
relating to this Agreement or any other Credit Document brought in the Supreme
Court of the State of New York, County of New York, or in the United States of
America District Court for the Southern District of New York or the competent
courts of the Republic of Chile, and hereby further irrevocably waive any claim
that any such suit, action or proceeding brought in any such court has been
brought in an inconvenient forum. Furthermore, Purchaser and Guarantors



                                       74.
<PAGE>   76

hereby agree to cause each Process Agent to execute and deliver to Vendor a
letter from each Process Agent to Vendor confirming Process Agent's acceptance
of the appointment by Purchaser and Guarantor, respectively, prescribed in
SECTION 9.11(C).

                  (d) WAIVER OF IMMUNITY. Each of Purchaser and Guarantors
irrevocably and unconditionally waives any immunity to which it or its property
may at any time be or become entitled, whether characterized as sovereign
immunity or otherwise, from any set-off or legal action in the Republic of Chile
or elsewhere, including immunity from service of process, immunity from
jurisdiction of any court or tribunal, and immunity of any of its property from
attachment prior to judgment or from execution of a judgment. This Agreement,
the other Credit Documents and the Forbearances are of a commercial rather than
the public or governmental nature and Purchaser and each Guarantor are not
entitled to claim immunity from legal proceedings with respect to itself or any
of its properties or assets on any grounds of sovereignty or otherwise under any
law or in any jurisdiction where an action may be brought for the enforcement of
any of the obligations arising under or relating to this Agreement or the other
Credit Documents.

                  (e) WAIVER OF JURY TRIAL. PURCHASER, EACH GUARANTOR, EACH
VENDOR, ADMINISTRATIVE AGENT AND COLLATERAL AGENT HEREBY IRREVOCABLY WAIVE THEIR
RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION, CLAIM OR OTHER
PROCEEDING ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT OR ANY
OF THE OTHER CREDIT DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR
THEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS OR OBLIGATIONS.

         9.12 CONFLICT IN CREDIT DOCUMENTS. To the extent there is any actual
irreconcilable conflict between the provisions of this Agreement and any other
Credit Document, the provisions of this Agreement shall prevail.

         9.13 MAXIMUM RATE. In no event whatsoever shall the interest rate and
other charges charged hereunder exceed the highest rate permissible under any
law which a court of competent jurisdiction shall, in a final determination,
deem applicable hereto. In the event that a court determines that Vendors have
received interest and other charges hereunder in excess of the highest rate
applicable hereto, Vendors shall promptly refund such excess amount to Purchaser
and the provisions hereof shall be deemed amended to provide for such
permissible rate.

         9.14 BROKER. Purchaser and Vendors represent and warrant to each other
that, with respect to the financing transaction herein contemplated, no Person
is entitled to any brokerage fee or other commission as a result of their
respective conduct and each agrees to indemnify and hold the other harmless
against any and all such claims for which the indemnitor is responsible.

         9.15 INDEMNIFICATION. Purchaser agrees to indemnify, save, and hold
harmless Administrative Agent, Collateral Agent, Vendors and their directors,
officers, agents, attorneys and employees (collectively, the "Indemnitees") from
and against: (a) any and all claims, demands, actions, or causes of action that
are asserted against any indemnitee by any Person if the claim, demand, action,
or cause of action arises out of or relates to a claim, demand, action, or cause
of action that the Person asserts or may assert against Purchaser, or any
officer, director or shareholder of Purchaser in their capacity as such; (b) any
and all claims, demands, actions or causes of action that are asserted against
any indemnitee (other than by Purchaser) if the claim,



                                       75.
<PAGE>   77

demand, action or cause of action arises out of or relates to the Forbearances,

Vendors under this Agreement or any transaction contemplated pursuant to this
Agreement; (c) any administrative or investigative proceeding by any
governmental agency arising out of or related to a claim, demand, action or
cause of action described in clauses (a) or (b) above; and (d) any and all
liabilities, losses, costs, or expenses (including outside attorneys' fees,
in-house counsel fees and disbursements) that any indemnitee suffers or incurs
as a result of any of the foregoing; provided, that Purchaser shall have no
obligation under this SECTION 9.15 to any Vendor, Collateral Agent or
Administrative Agent with respect to any of the foregoing arising out of the
gross negligence or willful misconduct of such Vendor, Collateral Agent or
Administrative Agent.

         9.16 SEVERABILITY. Whenever possible, each provision of this Agreement,
the Notes, Pagares and each of the other Credit Documents shall be interpreted
in such a manner as to be valid, legal and enforceable under the applicable law
of any jurisdiction. Without limiting the generality of the foregoing, in case
any provision of this Agreement, the Notes, Pagares or any of the other Credit
Document shall be invalid, illegal or unenforceable under the applicable law of
any jurisdiction, the validity, legality and enforceability of the remaining
provisions, or of such provision in any other jurisdiction, shall not in any way
be affected or impaired thereby.

         9.17 HEADINGS. Headings in this Agreement are for convenience of
reference only and are not part of the substance hereof.

         9.18 COUNTERPARTS. This Agreement may be executed in identical original
counterparts, each of which will be deemed to be an original and taken together
shall constitute one and the same instrument.

         9.19 SURVIVAL. All indemnities herein shall survive the execution and
delivery of this Agreement, the Notes and Pagares and the making and repayment
of all Forbearances.

         9.20 EFFECTIVENESS. This Agreement shall become effective on the date
on which Purchaser, Vendors, Administrative Agent and Collateral Agent shall
have signed a copy hereof and shall have delivered the same to the other
parties.

         9.21 CONFIDENTIALITY. Administrative Agent, Collateral Agent, and each
Vendor agrees that it will use its reasonable best efforts to keep confidential
and to cause any representative designated under SECTION 5.1(F) hereof to keep
confidential any material non-public information from time to time supplied to
it under this Agreement; provided, however, that nothing herein shall prohibit
Administrative Agent, Collateral Agent or any Vendor from disclosing such
information (a) to the extent Administrative Agent, Collateral Agent or such
Vendor in good faith believes it is required by statute, rule, regulation or
judicial process to divulge such information to any Person as required by such
authority; (b) to Administrative Agent's, Collateral Agent's or such Vendor's
counsel; (c) to Administrative Agent's, Collateral Agent's or such Vendor's
examiners, regulators, advisors, auditors or comparable Persons; (d) to any of
Administrative Agent's, Collateral Agent's or such Vendor's Affiliates; (e) to
any other Vendor or any assignee, transferee or participant, or any potential
assignee, transferee or participant, of all or any portion of Administrative
Agent's, Collateral Agent's or any Vendor's rights under this Agreement or the
other Credit Documents who is notified of the confidential nature of the
information and agrees to be bound by this provision or provisions reasonably



                                       76.
<PAGE>   78

comparable hereto; or (f) any other Person in connection with any litigation to
which any of Vendors is a party; and provided, further, that no Vendor shall
have any obligation under this SECTION 9.21 to the extent any such information
becomes available on a non-confidential basis from a source other than Purchaser
or its Subsidiaries or that any information becomes publicly available other
than by a breach of this SECTION 9.21. Each Vendor agrees it will use all
confidential information exclusively for the purpose of evaluating, monitoring,
selling, protecting or enforcing its rights under this Agreement and the other
Credit Documents. Without affecting any other rights of Purchaser, each Vendor
agrees that Purchaser shall be entitled to seek the remedies of injunction and
specific performance for any breach of the provisions of this SECTION 9.21.

         9.22 ENTIRE AGREEMENT. This Agreement, the Notes, the Pagares, the
other Credit Documents and the documents and agreements executed in connection
herewith and therewith constitute the final agreement of the parties hereto and
supersede any prior agreement or understanding, written or oral, with respect to
the matters contained herein and therein, including but not limited to any Term
Sheet between or among Purchaser, Parent and QUALCOMM through the date of this
Agreement.

         9.23 CURRENCY OF PAYMENT. The obligation of Purchaser to pay in Dollars
those amounts of the sums specified to be due in Dollars, under this Agreement
or the respective Credit Documents (the "Credit Document Currency") shall not be
deemed to have been novated, discharged or satisfied by any tender of (or
recovery under judgment expressed in) any currency other than the Credit
Document Currency, except to the extent to which such tender (or recovery) shall
result in the effective payment of such aggregate amount in the applicable
Credit Document Currency at the place where such payment is due and,
accordingly, the amount (if any) by which any such tender (or recovery) shall
fall short of such amount shall be and remain due to Administrative Agent,
Vendors or QUALCOMM, as the case may be, as a separate Obligation, unaffected by
judgment having been obtained (if such is the case) for any other amounts due in
respect of this Agreement or the Credit Documents.

         9.24 JUDGMENT CURRENCY. Purchaser agrees to indemnify each Vendor
against any loss incurred by it as a result of any judgment or order being given
or made for the payment of any amount due under any Pagare which is expressed
and paid in a currency (the "Judgment Currency") other than the currency in
which such amount was payable under this Agreement (the "Obligation Currency")
and as a result of any variation between (i) the rate of exchange at which the
Obligation Currency amount is converted into the Judgment Currency for the
purposes of satisfying such judgment or order, and (ii) the rate of exchange at
which such Vendor is able to purchase the Obligation Currency with the amount of
Judgment Currency actually received by such Vendor. The foregoing indemnity
shall constitute a separate and independent obligation of Purchaser and shall
continue in full force and effect notwithstanding any such judgment or order as
aforesaid. The term "rate of exchange" shall include any premiums and costs of
exchange payable in connection with the purchase of, or conversions into, the
relevant currency.

         9.25 ENGLISH LANGUAGE. This Agreement is made in the English language.
One Spanish language translation of this Agreement prepared at Purchaser's
expense by Chilean counsel to Purchaser and Chilean counsel to Vendors under
this Agreement shall be the agreed Spanish language translation hereof for all
purposes. Such translation and no other may be filed in one or more public
registries in the Republic of Chile or used in any proceeding in the



                                       77.
<PAGE>   79

Republic of Chile. For all purposes, the English language version hereof shall
be the original instrument and in all cases of conflict between the English and
the Spanish versions, the English version shall control.

         9.26 REINSTATEMENT. This Agreement shall continue to be effective or be
reinstated, as the case may be, if at any time payment and performance of the
obligations of Purchaser, or any part thereof, is, pursuant to applicable Law,
rescinded or reduced in amount, or must otherwise be restored or returned by
Administrative Agent, any Vendor or QUALCOMM. In the event that any payment or
any part thereof is so rescinded, reduced, restored or returned, such
obligations shall be reinstated and deemed reduced only by such amount paid and
not so rescinded, restored or returned.

        17,910,440. Leap was a wholly owned subsidiary of QUALCOMM prior to
        September 23, 1998. The basic and diluted net loss per common share was
        calculated by dividing the net loss for the fiscal years ended August
        31, 1998, 1997 and 1996 by the 17,647,685 shares of Leap common stock
        issued in the distribution to QUALCOMM's stockholders on September 23,
        1998.

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

FORWARD-LOOKING STATEMENTS

   This annual report, including Management's Discussion and Analysis of
Financial Condition and Results of Operations, contains certain forward-looking
statements that are not related to historical results, including statements
regarding the network deployment plans of Leap and its operating companies and
their plans for financing these deployments. Leap has based these
forward-looking statements largely on its current expectations and projections
about future events and financial trends affecting the financial condition of
its business. Forward-looking statements can be identified through their use of
words such as "believe," "may," "will," "estimate," "continue," "anticipate,"
"intend," "expect," and similar expressions in this annual report. Actual
results may differ materially from those stated or implied in the
forward-looking statements. The forward-looking statements contained in this
annual report are subject to a number of risks, uncertainties and assumptions
about Leap Wireless International, Inc., including the risks described below
under the heading "Risk Factors."

OVERVIEW

   Leap Wireless International, Inc. is a wireless communications carrier that
deploys, owns, operates and participates in CDMA telecommunications networks in
domestic and international markets with strong growth potential. Through its
operating companies, Leap has launched all digital wireless networks in Mexico,
Chile and the United States. Upon completion of its pending U.S. asset
acquisitions, Leap will have interests in wireless communications licenses
covering approximately 138 million potential customers in these three countries.
Leap's equity share will be approximately 67 million potential customers,
although this share may decrease as Leap's operating companies sell additional
equity.

   Domestic and international telecommunications markets are expanding rapidly.
Developing countries are seeking to increase their number of telephone lines as
a percentage of their population, known as teledensity, and to increase
competition among carriers. In addition, increased demand, decreased government
regulation, and new spectrum auctions have created domestic and international
opportunities for new providers to capture market share. Leap believes that
wireless is the cheapest and fastest way to increase teledensity and that it
possesses the expertise to oversee and manage the entry of new wireless
operating companies into today's competitive markets.

   Leap's domestic strategy is to offer consumers a simple and affordable
wireless service plan that allows them to make all of the local calls they want
for a low, flat monthly rate. Targeted at the mass consumer market, the service
is marketed under the name "Cricket(SM)" and is identified as "the around-town
phone(SM)" and "comfortable wireless(SM)." Cricket(SM) service was introduced in
March 1999 in Chattanooga, Tennessee using the existing infrastructure of Chase
Telecommunications, Inc., a company that Leap has agreed to acquire. The service
was launched under an agreement that requires the management of Chase
Telecommunications to control the business until Leap's proposed acquisition of
Chase Telecommunications receives all necessary governmental approvals and is
completed. The expansion of Cricket(SM) service to Nashville, Tennessee is
currently underway.

   Leap plans to introduce Cricket(SM) service to additional markets in the
United States in the future. Leap recently acquired 36 licenses in the federal
government's 1999 reauction of broadband PCS spectrum licenses. Leap has also
entered into agreements to purchase several licenses and is considering the
purchase of additional licenses in the United States.



                                       2

   In July 1999, the FCC issued a Memorandum Opinion and Order that found that
Leap was qualified to acquire and operate C-Block and F-Block PCS spectrum
licenses, subject to several conditions. The order also granted Leap's
application to acquire the 36 reauction licenses and approved the transfer of
four licenses in North Carolina and South Carolina to Leap, subject to the
specified conditions. In October 1999, the FCC issued the 36 reauction licenses
to Leap. Another wireless company has filed an application for review of the
FCC's order. Leap believes, however, that the FCC's order will be affirmed.

   Generally, Leap's international strategy is to invest in growth markets with
partners who provide familiarity with the local market and an ability to
facilitate deployment. For each joint venture in which it holds a significant
position, Leap is actively involved in the management of the venture, combining
its expertise in wireless markets with its technical expertise in CDMA. Leap is
committed to bringing the benefits of reliable, cost-effective and high-quality
voice and data services to its operating companies' customers.

   In Mexico, Leap's joint venture operating company, PEGASO, has launched
wireless service in three of Mexico's four largest markets - Monterrey,
Guadalajara and Tijuana - as part of a planned nationwide rollout. PEGASO
expects to launch service in Mexico City near the end of calendar 1999. During
the past year, PEGASO signed a roaming agreement with Sprint PCS that will allow
PEGASO's customers to use Sprint PCS's nationwide wireless network in the United
States. Under the agreement, Sprint PCS customers will also be able to utilize
PEGASO's network in Mexico.

   Chilesat Telefonia Personal, a wholly owned subsidiary of Leap, launched a
nationwide wireless network in Chile in September 1998. Chilesat Telefonia
Personal is being renamed SMARTCOM PCS and is referred to in the remainder of
this report as SMARTCOM. SMARTCOM's system is the first nationwide CDMA network
in Latin America. Leap increased its ownership interest in SMARTCOM from 50% to
100% in April 1999.

   The directors of the Transworld Companies, partially owned subsidiaries of a
company in which Leap has an indirect interest, recently voted to liquidate the
companies. The decision followed the Transworld Companies' loss of leased
satellite transmission capacity and the companies' failure to develop an
acceptable business plan that did not utilize satellite transmission. As a
result of these developments, Leap wrote down its indirect investment in the
Transworld Companies in the fourth quarter of fiscal 1999. In addition, Leap
stopped funding and wrote off its remaining investment in Metrosvyaz.

   Leap and its operating companies are in the early stages of development.
Start-up wireless communications companies typically require substantial capital
expenditures for the construction of their networks and license acquisition
costs. In addition, these companies typically incur significant marketing and
other expenses as they begin commercial operations. Accordingly, as Leap's
operating companies continue to build-out their networks, expand their
operations, and amortize their capitalized costs, their net operating losses and
Leap's proportionate share of the losses is expected to grow.

PRESENTATION

   Management's Discussion and Analysis of Financial Condition and Results of
Operations reviews the financial condition of the businesses that QUALCOMM
transferred to Leap in September 1998 as if Leap were a separate entity for all
periods discussed. Leap adopted the equity method of accounting for its
investment in Chase Telecommunications Holdings, Inc. in the third quarter of
fiscal 1999. Prior to that, Leap accounted for its investment in Chase
Telecommunications Holdings under the cost method. Accordingly, all prior
periods presented in the accompanying financial statements have been adjusted
retroactively in accordance with generally accepted accounting principles.

   In April 1999, Leap increased its ownership interest in SMARTCOM from 50% to
100%. As a result of the reporting lag it has adopted for its foreign operating
companies, Leap began fully consolidating SMARTCOM's results of operations in
June 1999, the beginning of the fourth quarter of fiscal 1999. Prior to that,
Leap accounted for its investment in SMARTCOM under the equity method of
accounting.

RESULTS OF OPERATIONS

FISCAL YEAR ENDED AUGUST 31, 1999 COMPARED TO FISCAL YEAR ENDED AUGUST 31, 1998

   Leap incurred a net loss of $164.6 million in fiscal 1999 compared to a net
loss of $46.7 million in fiscal 1998. The increase resulted primarily from
start-up costs associated with Leap's international operating companies. Leap's
share of these start-up costs, $100.3 million in fiscal 1999, is recorded as
equity in net loss of unconsolidated wireless operating companies. In addition,
in fiscal 1999 Leap recorded a write-down of equity investments of $27.2
million, interest expense and amortization of debt discount and facility fee of
$10.4 million, foreign currency transaction losses of $7.2 million, a gain on
the sale of a wholly owned subsidiary of $9.1 million and a gain on issuance of
stock by an unconsolidated wireless operating company of $3.6 million.

   As a direct result of the consolidation of SMARTCOM in the fourth quarter of
fiscal 1999, Leap recorded $3.9 million of operating revenues, $3.8 million of
cost of operating revenues, $4.5 million of additional selling, general and
administrative expenses, $5.3 million of additional depreciation and
amortization, $2.9 million of additional interest expense, and $7.2 million of
foreign currency transaction losses. SMARTCOM's full consolidation increased
Leap's net loss in fiscal 1999 by $9.9 million. During the prior fiscal year,
Leap did not report any operating revenues because all of its operating
companies were accounted for under the equity method of accounting. Leap's
operating companies did not generate material revenues in the prior fiscal year.

   Leap incurred $28.7 million of selling, general and administrative expenses
in fiscal 1999 compared to $23.9 million in fiscal 1998. The increase resulted
from the consolidation of SMARTCOM in the fourth quarter of fiscal 1999.
Excluding SMARTCOM, selling, general and administrative expenses remained
relatively flat, despite increased staffing as a result of Leap becoming a
stand-alone entity.

   Leap incurred an operating loss of $34.5 million in fiscal 1999 compared to
an operating loss of $23.9 million in fiscal 1998. The $10.6 million increase
primarily reflects the consolidation of SMARTCOM in the fourth quarter of fiscal
1999. Leap expects that fiscal 1999 operating revenues, operating expenses and
operating loss are not representative of future results, and believes operating
revenues and expenses will increase in the future. Leap expects substantial
growth in subscribers, operating revenues and operating expenses as a result of
its pending acquisition and consolidation of Chase Telecommunications, the
planned development and launch of Cricket(SM) service in multiple U.S. markets,
and an increase in marketing efforts in Chile. Leap also expects substantial
growth in PEGASO's subscribers, operating revenues and operating expenses;
however, because PEGASO is accounted for under the equity method, its operating
revenues and expenses are not fully consolidated.

   Equity in net loss of unconsolidated wireless operating companies was $100.3
million in fiscal 1999 compared to $23.1 million in fiscal 1998. The significant
increase in Leap's share of the net loss of its unconsolidated wireless
operating companies related primarily to the expenditures they incurred in
launching their network services, including marketing and other expenses, and
the amortization of their capitalized network costs. SMARTCOM, accounted
for under the equity method until the fourth quarter of fiscal 1999, launched
nationwide service in September 1998. PEGASO launched operations in Tijuana,
Guadalajara and Monterrey in February through September 1999. Chase
Telecommunications launched its traditional mobile service in the U.S. in
September 1998 and re-launched service utilizing Leap's Cricket(SM) wireless
concept in March 1999. In addition, Petrosvyaz, a Metrosvyaz joint venture,
launched commercial service in St. Petersburg in April 1999.

   Equity in net loss of unconsolidated wireless operating companies included a
$16.9 million asset impairment charge in fiscal 1999. Orrengrove, a company in
which Leap has an indirect ownership interest, recorded the charge when the
satellite that the Transworld Companies relied on to deliver long-distance
service in Russia failed. The Transworld Companies are partially owned
subsidiaries of Orrengrove. As a result of the satellite failure, the Transworld
Companies began using fiber lines to provide long-distance service as a
short-term alternative to the satellite transmission option they previously
used. They also began to explore long-term alternative methods to provide
long-distance services.



                                       4
<PAGE>   5

   After reviewing a series of alternative business plans that did not meet
their minimum financial performance criteria, the directors of the Transworld
Companies voted to liquidate the companies and to distribute their net assets to
their stockholders. As a result, Leap recorded a $17.6 million write-down in the
fourth quarter of fiscal 1999, reducing its investment in Orrengrove to the
liquidation proceeds Leap expects to receive.

   Leap also wrote off its remaining $9.6 million investment in Metrosvyaz in
fiscal 1999 as a result of its decision to stop funding loans to Metrosvyaz.
Metrosvyaz, a joint venture attempting to enter the Russian wireless
communications market, had not satisfied certain funding conditions under its
loan agreement with Leap and was in default of that agreement. In addition, Leap
had been prevented from securing full reporting and documentation of
performance, results and expenditures of Metrosvyaz in spite of repeated efforts
to obtain that information. Preliminary results of a special investigation of
Metrosvyaz also disclosed serious irregularities, including unaccounted for
funds and questionable contracts and payments.

   Leap expects its share of the equity losses of its unconsolidated wireless
operating companies to decrease in fiscal 2000 as a result of the consolidation
of SMARTCOM, the expected acquisition of Chase Telecommunications, the
discontinuance of funding to Metrosvyaz and the reduction in its percentage
equity interest in PEGASO from 33.3% to 28.6%. Leap expects the decrease to be
offset in part by increased equity losses from PEGASO's continued build-out in
Mexico.

   Interest expense in fiscal 1999 related primarily to borrowings under Leap's
credit agreement with QUALCOMM and the consolidation of $2.9 million of SMARTCOM
interest expense in the fourth quarter of fiscal 1999. SMARTCOM's interest
expense related primarily to the financing of its wireless communications
network. Leap expects interest expense to substantially increase in fiscal 2000
as a result of the consolidation of SMARTCOM and expected borrowings to fund the
construction of domestic telecommunications networks. Leap did not incur any
interest expense during the prior fiscal year.

   Foreign currency transaction losses of $7.2 million in fiscal 1999 reflected
unrealized foreign exchange losses recognized by SMARTCOM on U.S. dollar
denominated loans as a result of changes in the exchange rate between the U.S.
dollar and the Chilean peso during the fourth quarter of fiscal 1999.

   Gain on sale of wholly owned subsidiary of $9.1 million in fiscal 1999
resulted from Leap's sale of OzPhone Pty. Ltd., its Australian operating
company. OzPhone held wireless licenses but had not initiated service.

   Gain on issuance of stock by unconsolidated wireless operating company of
$3.6 million in fiscal 1999 effectively reflects a reduction in Leap's share of
PEGASO's accumulated losses as a result of a decrease in Leap's percentage
ownership of PEGASO. In July 1999, several other investors increased their
ownership interest in PEGASO by contributing $50 million of capital as
previously planned.

FISCAL YEAR ENDED AUGUST 31, 1998 COMPARED TO FISCAL YEAR ENDED AUGUST 31, 1997

   General and administrative expenses were $23.9 million for fiscal 1998,
compared to $1.4 million for fiscal 1997. The increase was due principally to
increases in business development activities relating to projects to create
Leap' operating companies in Mexico and Russia. These development activities
resulted in significantly higher consulting expenses and an increase in
QUALCOMM's corporate overhead allocated to Leap. Leap expects that general and
administrative expenses will increase in the future as a result of ongoing
development efforts on current and new projects.

   Equity in net loss of unconsolidated wireless operating companies for fiscal
1998 was $23.1 million, which represented Leap's wireless share of the net
losses of the wireless operating companies in which it then held an ownership
interest accounted for under the equity method of accounting. These losses
consisted of costs incurred before service launch during the network build-out
and testing phases, such as salary and related benefits, overhead expenses,
professional and consulting fees, and interest on long-term debt. Through August
31, 1998, there was no depreciation of network equipment and no



                                       5
<PAGE>   6
amortization of licenses as service had not been launched commercially. Equity
in net loss of unconsolidated wireless operating companies of $3.8 million for
fiscal 1997 primarily reflected Leap's equity share in the net loss of Chase
Telecommunications Holdings, which began network planning and initial build-out
activities earlier in the year.

LIQUIDITY AND CAPITAL RESOURCES

GENERAL

   Leap expects to require significant capital over the next several years to
fund the development and operation of its operating companies' existing wireless
projects and potential new ventures as well as corporate operations.

   Leap's primary sources of liquidity are $26.2 million of cash and cash
equivalents as of August 31, 1999, a $265 million credit agreement with
QUALCOMM, and vendor financing agreements related to the purchase and
installation of new telecommunications equipment. The credit agreement contains
a $35.2 million sub-facility to fund the corporate operating expenses of Leap at
the parent level, and a $229.8 million sub-facility to fund specified
investments of Leap. As of August 31, 1999, Leap had $145.6 million available to
it under the credit agreement, with $24.6 million available under the working
capital sub-facility and $121.0 million available under the investment
sub-facility. Amounts available under the investment sub-facility are allocated
to specific Leap projects and may not be reallocated to other projects without
QUALCOMM's written consent.

   As a condition to the FCC's recognition of Leap's qualification to hold
C-Block and F-Block licenses of PCS spectrum, Leap must take steps so that by
January 2001, QUALCOMM holds no more than 50% of Leap's outstanding debt
obligations. Leap cannot assure investors that it will be able to reduce its
debt to QUALCOMM to 50% or less of its outstanding debt obligations by January
2001.

   In the United States, Leap plans to construct wireless networks in numerous
markets. Leap expects to incur substantial expenditures in fiscal 2000 and
beyond to plan and construct these wireless networks. As is typical for start-up
telecommunications networks, Leap also expects the networks to incur operating
expenses significantly in excess of revenues in their early years of operations.

   Subsequent to the end of fiscal 1999, a domestic subsidiary of Leap agreed to
purchase $330 million of infrastructure products and services from a major
telecommunications supplier. The supplier agreed to finance these purchases plus
additional working capital at an interest rate equal to LIBOR plus 3.5% to 4.25%
or a bank base rate plus 2.5% to 3.25%, in each case with the specific rate
based on the ratio of total indebtedness to EBITDA (earnings before interest,
taxes, depreciation and amortization). Principal payments are scheduled to begin
after three years with a final maturity after eight years. Repayment is weighted
to the later years of the repayment schedule. The supplier credit agreement is
secured and contains covenants and conditions typical for a loan of this type.
At the same time, Leap's subsidiary also agreed to purchase $330 million of
next-generation infrastructure products which are currently in development and
related services from a second major telecommunications supplier. Purchases from
the second supplier will be on substantially similar terms, including financing.
This second agreement is subject to approval of the supplier's board of
directors.

   Leap expects to fund the cost of developing and operating domestic networks
in fiscal 2000 largely through vendor financing and amounts available under its
credit agreement with QUALCOMM. In addition, Leap expects that it will need to
raise additional capital to fund its planned roll-out of domestic networks and
acquisitions of licenses in fiscal 2000. As a result, Leap is exploring debt and
equity financing alternatives. Leap cannot assure investors that it will be able
to raise additional capital in fiscal 2000 or that additional capital will be
available to it on acceptable terms. If Leap does not obtain additional
financing, management believes it can reduce its capital needs sufficiently to
meet its liquidity requirements through fiscal 2000 by slowing or reducing the
scope of its planned deployments in the United States and by reducing or
deferring additional license acquisitions.



                                       6

   Leap and Chase Telecommunications are parties to a credit agreement under
which Leap provides, at its discretion, working capital to Chase
Telecommunications. The parties have agreed in principle to increase the maximum
amount that may be drawn under the facility to $45 million. At August 31, 1999,
principal borrowings under the working capital facility totaled approximately
$32.8 million.

   Chase Telecommunications is preparing to launch Cricket (SM) service in
additional markets in Tennessee. Until Leap's pending acquisition of Chase
Telecommunications is completed, a Leap subsidiary plans to purchase the
equipment and services required by Chase Telecommunications under the
subsidiary's existing equipment purchase and financing agreements, and to resell
the equipment and services to Chase Telecommunications on substantially similar
terms, including financing. If Leap does not complete the acquisition of Chase
Telecommunications by approximately October 2000, Leap is required to purchase
from the vendor the note Leap's subsidiary will provide to finance its purchase
of equipment and services for Chase Telecommunications.

   Leap's wholly owned subsidiary, SMARTCOM, expects to incur significant
capital expenses over the next several years. SMARTCOM plans to upgrade existing
equipment and purchase additional equipment to accommodate expected subscriber
growth and to enhance the quality and reliability of its system. As a relatively
new wireless operating company, SMARTCOM also expects to incur operating losses
for the next several years.

   Leap intends to finance the planned upgrade and expansion as well as the
operation of SMARTCOM's network in fiscal 2000 through borrowings under Leap's
credit agreement with QUALCOMM, the proceeds of equipment financing agreements
that Leap expects to negotiate in connection with planned equipment purchases by
SMARTCOM, and capital from additional financing transactions. Leap and an
equipment supplier are currently negotiating a new financing agreement for
SMARTCOM, and SMARTCOM has engaged an investment banker to assist it in selling
equity. SMARTCOM is also exploring other capital raising alternatives. Leap
cannot assure investors that SMARTCOM will obtain additional vendor funding or
conclude a sale of equity or other financing transaction in fiscal 2000. If
SMARTCOM does not obtain additional financing in fiscal 2000, Leap expects to
delay or reduce the scope of SMARTCOM's planned expansion.

   SMARTCOM was in default of certain covenants in an equipment financing
agreement at August 31, 1999. Subsequent to the end of the fiscal year, SMARTCOM
and the equipment vendor amended the agreement, revising the covenants that
were in default and extending the loan repayment schedule.

   In May 1999, PEGASO entered into a $100 million loan agreement with an
equipment vendor and several banks. Leap guaranteed 33% of PEGASO's
obligations under that agreement. In July 1999, several existing investors
contributed $50 million to PEGASO as previously planned. PEGASO expects to fund
a large portion of its development and operating activities in fiscal 2000 with
cash from operations, proceeds of the $50 million investment, and borrowings
under the $100 million loan agreement. In addition, PEGASO is seeking additional
debt and equity financing, including additional vendor financing. Leap has no
further commitment to contribute capital to PEGASO, although several other
existing investors are committed to contribute $50 million by August 2000.

OPERATING ACTIVITIES

   Leap used $34.1 million in cash for operating activities in fiscal 1999,
compared to $18.4 million in fiscal 1998. Cash used in operating activities in
fiscal 1999 included $8.5 million attributable to the consolidation of SMARTCOM
during the fourth quarter. Leap expects that cash used in operating activities
will increase further as it expands its project development efforts. In
addition, Leap expects that cash used in operating activities will increase
substantially in the future as a result of its acquisition and consolidation of
SMARTCOM, its pending acquisition of Chase Telecommunications, and other Leap
activities related to the launch of its U.S. network.



                                       7
<PAGE>   8

INVESTING ACTIVITIES

   Cash used in investing activities was $158.3 million in fiscal 1999 compared
to $140.7 million in fiscal 1998. Significant investments in fiscal 1999
consisted of $124.5 million of investments in and loans to Leap's operating
companies ($71.4 million made before Leap began to operate as an independent
company), $28.0 million for Leap's acquisition of the remaining shares of
SMARTCOM, and $18.7 million on U.S. license acquisitions. Cash used in
investing activities was offset by $16.0 million provided from the sale of
Leap's OzPhone subsidiary. In fiscal 2000, Leap and its subsidiaries expect to
make significant investments in capital assets, including network equipment and
wireless communications licenses.

FINANCING ACTIVITIES

   Cash provided by financing activities during fiscal 1999 amounted to $216.5
million, representing $95.3 million of funding from QUALCOMM for Leap's
operating and investing activities prior to the distribution of Leap common
stock to QUALCOMM's stockholders in September 1998 and $111.1 million of net
borrowings under the credit agreement with QUALCOMM after the distribution.

CURRENCY FLUCTUATION RISKS

   Leap reports its financial statements in U.S. dollars. Leap's international
operating companies report their results in local currencies. Consequently,
fluctuations in currency exchange rates between the U.S. dollar and the
applicable local currency will affect Leap's results of operations as well as
the value of its ownership interests in its operating companies.

   Generally, Leap's international operating companies generate revenues which
are paid in their local currency. However, many of these operating companies'
major contracts, including financing agreements and contracts with equipment
suppliers, are denominated in U.S. dollars. As a result, a significant change in
the value of the U.S. dollar against the national currency of an operating
company could result in a significant increase in the operating company's
expenses and could have a material adverse effect on the operating company and
on Leap. In some emerging markets, including Mexico, significant devaluations of
the local currency have occurred and may occur again in the future.

   Leap does not currently have a policy to systematically hedge against foreign
currency exchange rate or interest rate risks.

INFLATION

   Inflation has had and may continue to have negative effects on the economies
and securities markets of emerging market countries and could have negative
effects on Leap's operating companies and any new start-up project in those
countries, including their ability to obtain financing. Chile and Mexico, for
example, have periodically experienced relatively high rates of inflation. The
operating companies, where permitted and subject to competitive pressures,
intend to increase their tariffs to account for the effects of inflation.
However, in those jurisdictions where tariff rates are regulated or specified in
the license, the operating companies may not successfully mitigate the impact of
inflation on their operations.

YEAR 2000 ISSUE

   The Year 2000 issue arises from the fact that many computer software programs
use two digits rather than four to represent a specific year. Any computer
programs that have date-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in a system failure
or miscalculation causing disruptions of operations including a temporary
inability to process transactions, send invoices or engage in similar normal
business activities.



                                       8
<PAGE>   9

   Leap and its operating companies have recently begun their respective
businesses and have designed and built their wireless communications networks
and support systems with the Year 2000 issue in mind. The recent acquisition of
network equipment and software does not guarantee, however, that such equipment
and software will be Year 2000 compliant.

   Leap and each of its operating companies have conducted an inventory to
identify its systems that may be subject to Year 2000 problems and that are
critical to its business and operations. Each of Leap's operating companies has
been working with its primary telecommunications and business software systems
vendors on Year 2000 readiness issues. They have informed Leap and its operating
companies that their products are Year 2000 ready or, if not ready, have agreed
to a remediation and test program to be implemented prior to the Year 2000.

   Although Leap expects that its operating companies' critical network
infrastructure systems will be Year 2000 compliant, Leap's operating companies
may experience difficulties with systems maintained by third parties. For
example, other telecommunications systems that interconnect with the operating
companies' systems (such as landline, long-distance and power systems) could
malfunction and disrupt their ability to provide wireless service. Leap's
operating companies are not currently aware of evidence that a failure is likely
to occur in their service areas. However, Leap's operating companies continue to
evaluate the risks associated with third-party interfaces and Year 2000 issues.

     Leap continues to work at the corporate level and with its operating
companies to evaluate Year 2000 risks and the development of any required
remediation and contingency plans. Leap expects that Year 2000 testing and
preparation will continue during the remainder of 1999. To date, Leap has not
incurred any material costs in support of the Year 2000 issue. Leap estimates
that it will spend $500,000 or less in calendar year 1999 to review and correct
any non-compliance as well as to support the Leap operating companies and
support material third party relationships.

   Leap cannot assure investors that Leap and its operating companies will be
able to identify all Year 2000 problems in their systems and third-party systems
in advance of the occurrence of those problems. In addition, we may not be able
to remedy any problems that may occur on a timely basis. A material Year 2000
problem could result in an interruption in, or a failure of, certain normal
business activities, including the provision of wireless service by the Leap
operating companies. Such a problem could materially and adversely affect the
business and operations of Leap and its operating companies.

   Leap expects that its operating companies in the United States, Mexico and
Chile, and their critical equipment vendors, will have personnel available to
assess and remedy any Year 2000 problem that may occur early in the year 2000.

FUTURE ACCOUNTING REQUIREMENTS

   In April 1998, the Accounting Standards Executive Committee issued Statement
of Position ("SOP") No. 98-5, "Reporting on the Costs of Start-Up Activities,"
which Leap will be required to adopt for fiscal year 2000. This SOP provided
guidance on the financial reporting of start-up and organizational costs. It
requires start-up and organizational costs to be expensed as incurred. Leap does
not expect that the adoption of SOP No. 98-5 will have a material impact on its
consolidated financial position or results of operations.

   In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133 ("FAS 133"), "Accounting for Derivative Instruments and Hedging Activities,"
which Leap must adopt for fiscal year 2001. This statement establishes a new
model for accounting for derivatives and hedging activities. Under FAS 133, all
derivatives must be recognized as assets and liabilities and measured at fair
value. Leap does not expect that the adoption of this new accounting standard
will have a material impact on its consolidated financial position or results of
operations.

RISK FACTORS

LEAP HAS A LIMITED OPERATING HISTORY

   Leap has only operated as an independent company since September 1998.
Because Leap and each of its operating companies are at an early stage of
development, Leap faces risks generally associated with establishing a new
business enterprise. When considering Leap's prospects, investors must consider
the risks, expenses and difficulties encountered by companies in their early
stage of development. These risks include possible disruptions and
inefficiencies associated with rapid growth and workplace expansion, the
difficulties associated with raising money to finance new enterprises and the
difficulties of establishing a significant presence in highly competitive
markets. Investors must also consider the risks Leap will face as a company in
new and evolving wireless communications markets experiencing rapid growth.

LEAP HAS A HISTORY OF LOSSES AND ANTICIPATES FUTURE LOSSES

   Leap experienced net losses of $164.6 million in fiscal 1999, $46.7 million
in fiscal 1998 and $5.2 million in fiscal 1997. According to generally accepted
accounting principles, Leap must recognize some or all of its operating
companies' losses. These losses are likely to be significant for the next
several years as Leap's operating companies launch service in new markets and
seek to increase their subscriber base in new and existing markets. We cannot
assure investors that Leap or any of its operating companies will generate
profits in the short term or at all. If Leap or any of its operating companies
fails to achieve profitability, that failure could have a negative effect on the
market value of the Leap common stock.

LEAP AND ITS OPERATING COMPANIES MAY FAIL TO RAISE REQUIRED CAPITAL

    Leap and its operating companies require significant additional capital to
build-out and operate their planned networks and for general working capital
needs. Leap also requires additional capital to invest in any new wireless
opportunities, including capital for license acquisition costs. Capital markets
have recently been volatile and uncertain. We cannot assure investors that these
markets will improve or that Leap or its operating companies can access these
markets to raise additional capital. Developing companies in emerging markets
such as Latin America have found it particularly difficult to raise capital. An
operating company's failure to raise required capital could adversely affect the
value and prospects of that company and thus, could adversely affect the value
and prospects of Leap. If Leap fails to obtain required new financing, that
failure could also affect the value and prospects of Leap. For example, if Leap
is unable to access capital markets, it may have to restrict its activities or
sell its interests in one or more operating companies earlier than planned or at
a "distressed sale" price.

HIGH LEVELS OF DEBT COULD ADVERSELY AFFECT LEAP'S BUSINESS AND FINANCIAL
CONDITION

   Leap expects to obtain much of its required capital through debt financing.
Most of the debt financing bears or is likely to bear a variable interest rate,
exposing Leap to interest rate risk.

   The high leverage of Leap could have important consequences, including the
following:

   -  the ability of Leap to obtain additional financing may be impaired;

   -  a substantial portion of Leap's future cash flows from operations must be
      dedicated to the payment of its debt, thus reducing the funds available
      for operations and investments;

   -  Leap's leverage may reduce its ability to adjust rapidly to changing
      market conditions and may make Leap more vulnerable to future downturns in
      the general economy; and



                                       10
<PAGE>   11

   -  high levels of debt may reduce the value of stockholders' investment in
      Leap because debt holders have priority regarding the assets of Leap in
      the event of a bankruptcy or liquidation.

   We cannot assure investors that Leap will have sufficient future cash flows
to meet its debt payments or that Leap will successfully refinance any of its
debt at maturity.

   Leap's operating companies also expect to be highly leveraged. As a result,
Leap's operating companies face the same types of risks with respect to their
heavy debt level as are described above. Leap's operating companies will face
additional risks with respect to their equipment financing arrangements from
vendors. These equipment financings will depend on meeting planned levels of
performance. If any Leap operating company fails to meet performance
requirements, its equipment financing may be restricted or cancelled.

   QUALCOMM has provided significant financing to Leap and its operating
companies and has also agreed to provide them with significant additional
financing. We cannot assure you Leap and its operating companies will not
experience disputes or difficulties with QUALCOMM with respect to these
agreements. The business and prospects of Leap and its operating companies would
be adversely affected if they were not able to draw funds under their financing
agreements with QUALCOMM.

INTERNATIONAL RISKS COULD ADVERSELY AFFECT LEAP'S BUSINESS

   Leap faces many risks from its international activities. Leap's operating
companies largely depend on the economies in which they operate and these
economies are in various stages of development. Some of these markets are
subject to rapid fluctuations in currency exchange rates, consumer prices,
inflation, employment levels and gross domestic product. Economic difficulties
in Russia, for example, negatively affected the development of
telecommunications companies in which Leap holds minority interests.

   In addition, foreign law and courts govern many of the agreements of Leap's
operating companies. Other parties may breach or may make it difficult to
enforce these agreements. Further, public awareness of the risks associated with
international operations may increase the volatility of the market price of
Leap's common stock.

   Leap will also face country-specific risks. The country-specific risks that
Leap faces include:

          Risks Associated With Doing Business in Mexico: Mexico's currency and
financial markets continue to experience volatility. The impact on the Mexican
economy of the economic crisis which began in Asia and then spread to Eastern
Europe and Brazil has affected the ability of Mexican companies to access the
capital markets. We cannot assure you that the ability of Mexican companies to
access the capital markets will improve or that it will not deteriorate further
in the future. The economy of Mexico historically also has close ties to
fluctuations in the price of oil and petroleum products. Fluctuations in the
prices of these products and continuing political tensions in Mexico could
negatively impact Leap's prospects in Mexico. A number of international
telecommunications companies, including Bell Atlantic, AT&T, MCI, Motorola,
Nextel and SBC, as well as local competitors such as Telmex and other Mexican
telecommunications companies, continue to actively engage in developing
telecommunications services in Mexico. Most of these competitors have
substantially greater resources than PEGASO. We cannot assure you that PEGASO
will be able to compete successfully.

          Risks Associated With Doing Business in Chile: The Leap operating
company in Chile depends largely on the economy of that country. Fluctuations in
the price of natural resources historically affect the economy of Chile. The
economic crisis that began in Asia and spread to Eastern Europe and Brazil has
negatively impacted some commodity prices, which could negatively impact Leap's
prospects in Chile. Although Chilean prices and its currency generally have been
stable, this stability has required continued intervention by the Chilean
government. Also, the Chilean telecommunications market historically has been
very price competitive. The existing competitors in Chile include BellSouth,
Telefonica and Entel, all of whom have greater financial resources and more
established operations than SMARTCOM. We cannot assure you that SMARTCOM will
compete successfully.



                                       11
<PAGE>   12
LEAP'S FAILURE TO MAINTAIN ITS EXISTING LICENSES AND OBTAIN NEW LICENSES COULD
AFFECT ITS COMPETITIVE POSITION

   Leap's operating companies must maintain their existing telecommunications
licenses to continue offering wireless telecommunications services. Changes in
regulations or an operating company's failure to comply with the terms of a
license could result in a loss of the license, penalties and fines. For example,
an operating company could lose its license if it failed to construct or operate
a wireless network as required by the license. If a Leap operating company loses
a license, that loss could have a material adverse effect on the operating
company and on Leap.

   State regulatory agencies, the FCC, the United States Congress and the courts
regulate the operation of wireless telecommunications systems and the use of
licenses in the United States. We cannot assure you that the FCC, Congress, the
courts or state agencies having jurisdiction over Leap's operating companies
will not take actions that could negatively affect Leap's business and financial
condition.

   Foreign governmental authorities regulate the operation of wireless
telecommunications systems and the use of licenses in the foreign countries in
which Leap's operating companies operate. In some cases, the regulatory
authorities also operate the competitors of Leap's operating companies. Changes
in the current regulatory environment of these markets could have a negative
effect on Leap. In addition, the regulatory frameworks in some of these
countries are relatively new and the interpretation of regulations is uncertain.
This uncertainty may create legal risks for Leap's operating companies.

   Leap believes that intense competition will surround the acquisition of new
telecommunications licenses. If Leap fails to obtain new licenses, or cannot
otherwise participate in companies that obtain new licenses, Leap's ability to
expand its operations would be limited.

THE FCC'S DECISION THAT LEAP IS QUALIFIED TO HOLD C-BLOCK AND F-BLOCK LICENSES
IS SUBJECT TO REVIEW AND APPEAL

   Leap's business plan anticipates and depends on its acquisition and operation
of C-Block and F-Block spectrum licenses in the United States. Although C-Block
and F-Block licenses are generally more available and are less expensive to
obtain than licenses in other spectrum blocks, a licensee may hold these
licenses only if it qualifies as a "designated entity" under FCC rules.

   In July 1999, the FCC issued an opinion and order that found that Leap was
entitled to acquire C-Block and F-Block licenses. The order also approved Leap's
acquisition of the 36 C-Block licenses that Leap won in the FCC's 1999 spectrum
reauction, and approved the transfer to Leap of four F-Block licenses covering
portions of North and South Carolina, in each case subject to the fulfillment of
certain conditions. In October 1999, the FCC issued the 36 reauction licenses
to Leap.

   Each of the conditions imposed by the FCC has been satisfied except for the
condition that Leap reduce its debt to QUALCOMM to 50% or less of its
outstanding debt by January 2001 and except for Leap's continuing obligation,
during the designated entity holding period for its C-Block and F-Block spectrum
licenses, to ensure that persons who are or were previously officers or
directors of QUALCOMM do not comprise a majority of Leap's Board of Directors or
a majority of its officers. Leap anticipates satisfying the debt reduction
condition through additional financing activities, but Leap cannot guarantee
that it will be able to reduce its debt to QUALCOMM to the required level. If
Leap fails in the future to meet any of the conditions imposed by the FCC or
otherwise fails to maintain its qualification to own C-Block and F-Block
licenses, that failure would have a material adverse effect on Leap's financial
condition and business prospects.

   Various parties, including the U.S. Small Business Administration, previously
challenged Leap's qualification to hold C-Block and F-Block licenses, and a
wireless operating company has requested that the FCC review its order. In
addition, one or more of such parties may appeal the FCC's order approving
Leap's acquisition of C-Block and F-Block licenses.



                                       12

<PAGE>   13
Leap cannot assure investors that it will prevail in connection with any such
appeal or that it will remain qualified to hold C-Block or F-Block spectrum
licenses.

CALL VOLUME UNDER CRICKET(SM) FLAT PRICE PLANS COULD EXCEED THE CAPACITY OF
LEAP'S WIRELESS NETWORKS

   Leap's strategy in the United States, marketed under the name Cricket(SM), is
to offer consumers a service plan that allows them to make all of the local
calls they want for a flat monthly rate. Leap's business plans for this strategy
assume that Cricket(SM) customers will use their wireless phones for
substantially more minutes per month than customers who purchase service from
other providers under more typical plans. Leap intends to design its U.S.
networks to accommodate the expected high call volume. Leap also believes that
the CDMA technology it plans to utilize is particularly well suited to support
high volume applications. In addition, Leap expects that the capacity of CDMA
products will be enhanced in the future with third generation technologies.
Despite these plans, if wireless use by Cricket(SM) subscribers exceeds the
capacity of Leap's future networks, service quality may suffer and Leap may be
forced to raise the price of its Cricket(SM) service to reduce volume or
otherwise limit the number of new subscribers. If Leap's planned networks cannot
handle the call volumes they experience, Leap's competitive position and
business prospects in the U.S. are likely to suffer materially.

LEAP MAY EXPERIENCE DIFFICULTIES IN CONSTRUCTING AND OPERATING ITS
TELECOMMUNICATIONS NETWORKS

   Leap and its operating companies will need to construct new
telecommunications networks and expand existing networks. Leap and its operating
companies will be heavily dependent on its suppliers and contractors to
successfully complete these complex construction projects. Leap and its
operating companies may experience quality deficiencies, cost overruns and
delays on their construction projects, including deficiencies, overruns and
delays not within their control or the control of their contractors. We cannot
assure you that Leap and its operating companies can complete construction
projects for the amount budgeted or on a timely basis. A failure to
satisfactorily complete construction projects could jeopardize spectrum licenses
and subscriber contracts. As a result, a failure of this type could have a
negative effect on Leap and its operating companies.

   Even if Leap and its operating companies complete construction in a timely
and cost effective manner, they will also face challenges in managing and
operating their telecommunications systems. These challenges include operating
and maintaining the telecommunications operating equipment and managing the
sales, advertising, customer support, billing, and collection functions of the
business. A failure by Leap or any of its operating companies in any of these
areas could undermine customer satisfaction, increase churn, reduce revenues and
otherwise negatively effect Leap and its operating companies.

   Several of Leap's operating companies have experienced reliability problems
with respect to their network infrastructure equipment in their initial year of
operation. Leap and its operating companies are working with vendors to address
these problems. If the network infrastructure equipment that Leap's operating
companies have purchased ultimately fails to perform as expected, that failure
could have a material adverse effect on Leap and its operating companies.

A DETERMINATION THAT LEAP IS AN INVESTMENT COMPANY COULD ADVERSELY AFFECT ITS
BUSINESS

   A large portion of Leap's assets consists of investments in entities in which
Leap does not own an interest greater than 50%. In addition, Leap expects that
its ownership interests in its operating companies will vary over time as the
ventures raise additional capital and as Leap considers participating in new
ventures. As a result, Leap could be subject to the registration requirements of
the Investment Company Act of 1940. The Investment Company Act of 1940 requires
registration of companies that engage primarily in the business of investing in
stock. Because Leap intends to actively participate in managing the business
operations of its operating companies, Leap does not believe it is primarily
engaged in the business of investing in stock. Leap intends to monitor and
adjust its interests in its operating companies to the extent practical to avoid
subjecting itself to the Investment Company Act of 1940. In addition, to clarify
Leap's status under the Investment Company Act of 1940, in September 1998 Leap
filed a request for an exemptive order from the SEC



                                       13
<PAGE>   14
declaring Leap to be primarily engaged in a business other than investing in
stock. The SEC has not yet ruled on Leap's application. We cannot assure
investors that the requested exemptive order will be granted. If we must
register as an investment company under the Investment Company Act of 1940,
compliance with these regulations will negatively impact Leap's business.

LEAP FACES SIGNIFICANT COMPETITION

   The wireless telecommunications industry is very competitive and competition
is increasing. Many competitors have substantially greater resources than Leap
and its operating companies. We cannot assure you that Leap or its operating
companies will compete successfully.

   Although the deployment of advanced telecommunications services is in its
early stages in many developing countries, Leap believes competition is
increasing as businesses and foreign governments realize the market potential of
telecommunications services. Leap's operating companies currently face
competition from existing wireless telecommunications providers. In addition, a
number of large telecommunications companies are implementing programs to deploy
telecommunications services in both developing and developed countries. Leap's
operating companies also compete against landline carriers, including
government-owned telephone companies. In addition, Leap's operating companies
may face competition with technologies and services introduced in the future.
Although Leap's operating companies intend to use relatively new technologies,
newer technologies may make their technologies obsolete. Leap also expects the
price that its operating companies charge for their products and services in
some regions will decline over the next few years as competition increases in
their markets.

   In the United States, Leap will compete directly with other wireless
providers in each of its markets, many of whom have greater resources than Leap
and entered the market before Leap. A few of Leap's competitors operate wireless
telecommunications networks covering most of the United States. Competitors'
earlier entry and broader presence in the U.S. telecommunications market may
have a negative effect on Leap's ability to successfully implement its strategy.
In addition, other wireless providers could attempt to implement Leap's strategy
of providing local service at a flat-rate. Providers who offered such a service
in Leap's market areas would directly compete against Leap in its market niche.
Also, it is likely that some competitors will market other services, including
cable television access, landline telephone service and Internet access, that
Leap does not currently intend to market. Leap also expects to compete with new
entrants to the U.S. wireless markets as well as other telecommunications
technologies, including paging, enhanced specialized mobile radio and global
satellite networks.

THE LOSS OF KEY PERSONNEL COULD HARM LEAP'S BUSINESS

   Leap believes its success depends on the contributions of a number of its key
personnel. Leap's key personnel include Harvey P. White, Chairman of the Board
and Chief Executive Officer; and Susan G. Swenson, President and Chief Operating
Officer. If Leap lost the services of key personnel, that loss could materially
harm Leap. Leap does not maintain "key person" life insurance on any employee.

ISSUANCE OF SHARES RESERVED FOR FUTURE ISSUANCE WILL REDUCE YOUR PERCENTAGE
OWNERSHIP INTEREST IN LEAP

   On September 30, 1999, 18,428,330 shares of Leap common stock were
outstanding. In addition, 14,580,297 additional shares of Leap common stock were
reserved for issuance on September 30, 1999, including:

   -  4,500,000 shares reserved for issuance upon exercise of the warrant issued
      to QUALCOMM;

   -  3,674,430 shares reserved for issuance to employees, officers, directors
      and consultants under Leap's equity incentive plans;



                                       14
<PAGE>   15

   -  4,136,373 shares reserved for issuance upon exercise of options to
      purchase Leap common stock granted in connection with the distribution of
      Leap's common stock to the stockholders of QUALCOMM; and

   -  2,269,494 shares reserved for issuance upon conversion of outstanding
      QUALCOMM Trust Convertible Preferred Securities.

   If Leap were to issue all of the shares reserved for issuance, the current
holders of shares of Leap's currently outstanding common stock would hold only
56% of the outstanding common stock.

LEAP HAS IMPLEMENTED ANTI-TAKEOVER PROVISIONS THAT COULD PREVENT AN ACQUISITION
OF LEAP THAT IS BENEFICIAL TO ITS STOCKHOLDERS

   Leap's charter and bylaws could make it more difficult for a third party to
acquire Leap, even if doing so would be beneficial to its stockholders. Leap's
charter and bylaw provisions could diminish the opportunities for a stockholder
to participate in tender offers. The charter and bylaws may also restrain
volatility in the market price of the Leap common stock resulting from takeover
attempts. In addition, the Board of Directors may issue preferred stock that
could have the effect of delaying or preventing a change in control of Leap. The
issuance of preferred stock could also negatively affect the voting power of the
holders of Leap common stock. The provisions of the charter and bylaws may have
the effect of discouraging or preventing an acquisition of Leap or a sale of its
businesses.

   The preferred stock purchase rights attached to each share of Leap common
stock could discourage, delay or prevent an acquisition of Leap at a premium
price. The purpose of the preferred stock purchase rights is to assure that all
of Leap's stockholders receive fair and equal treatment in the event of any
proposed takeover of Leap. The preferred stock purchase rights also guard
against a party using abusive tactics to gain control of Leap without paying all
stockholders a control premium. The preferred stock purchase rights will cause
substantial dilution to a person or group acquiring 15% or more of Leap's stock
if the acquisition is not approved by the Board of Directors, although the
rights should not interfere with any merger approved by the Board of Directors.

   Leap's ownership of U.S. wireless telecommunications licenses that may only
be transferred to licensees who meet restrictive eligibility conditions also
adversely affects the ability of third parties to acquire Leap.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

   Interest Rate Risk. Leap's exposure to market risk for changes in interest
rates relates primarily to its variable rate long-term debt obligations. The
general level of U.S. interest rates and/or LIBOR affect the interest expense
that Leap recognizes on its variable rate long-term debt obligations. As of
August 31, 1999, the principal amounts of Leap's variable rate long-term debt
obligations amounted to $210.3 million. An increase of 10% in interest rates
would increase Leap's interest expense for fiscal year 2000 by approximately
$2.3 million. This hypothetical amount is only suggestive of the effect of
changes in interest rates on Leap's results of operations in fiscal year 2000.

     Foreign Exchange Market Risk. The long-term debt obligations of Leap's
wholly owned Chilean subsidiary, SMARTCOM, which are denominated in the U.S.
dollar, are subject to the effects of currency fluctuations and may affect
reported earnings and losses. A significant change in the value of U.S. dollar
against the Chilean peso could result in a significant increase in the
consolidated expenses of Leap. As of August 31, 1999, SMARTCOM's long-term debt
obligations that were denominated in the U.S. dollar amounted to $101.7 million.
Leap's results of operations would be negatively impacted by approximately $11.9
million for fiscal year 2000 if the U.S. dollar were to appreciate against the
Chilean peso by 10%. This hypothetical amount is only suggestive of the effect
of currency fluctuations on Leap's results of operations in fiscal year 2000.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  THE COMPANY

The Company and Nature of Business

     Leap Wireless International, Inc., a Delaware corporation, and its wholly
owned and majority-owned subsidiaries (the "Company" or "Leap") is a wireless
communications carrier that deploys, owns and operates networks in domestic and
international markets. Through its operating companies, Leap has launched
all-digital wireless networks in the United States, Chile and Mexico. The
Company was incorporated on June 24, 1998 as a wholly owned subsidiary of
QUALCOMM Incorporated ("QUALCOMM"). On September 23, 1998 (the "Distribution
Date"), QUALCOMM distributed all of the outstanding shares of common stock of
the Company to QUALCOMM's stockholders as a taxable dividend (the
"Distribution"). In connection with the Distribution, one share of Company
common stock was issued for every four shares of QUALCOMM common stock
outstanding on September 11, 1998. Following the Distribution, the Company and
QUALCOMM operate as independent companies.

The Distribution

     QUALCOMM transferred to the Company its equity interests in the following
domestic and international wireless communications operating companies: Chilesat
Telefonia Personal, S.A., to be renamed SMARTCOM PCS ("SMARTCOM"), Pegaso
Telecomunicaciones, S.A. de C.V. ("PEGASO"), Chase Telecommunications Holdings,
Inc. ("Chase"), Metrosvyaz Limited ("Metrosvyaz"), Orrengrove Investments
Limited ("Orrengrove"), OzPhone Pty. Ltd. ("OzPhone"), and certain other
development stage businesses which are today operating under the trade name
"Cricket" (collectively, the "Leap Operating Companies"). Metrosvyaz, Orrengrove
and OzPhone have been subsequently written off, written down or sold. See Notes
3 and 4. QUALCOMM also transferred to the Company cash and its right to receive
payment from working capital and other loans QUALCOMM made to the Leap Operating
Companies, as well as certain miscellaneous assets and liabilities. The
aggregate net tangible book value of the assets transferred by QUALCOMM to the
Company in connection with the Distribution was approximately $236 million. The
consolidated financial statements reflect the Company as if it were a separate
entity for all periods presented.

Additional Capital Needs

     The Company experienced net losses for the years ended August 31, 1999,
1998 and 1997 of $164.6 million, $46.7 million and $5.2 million, respectively.
Further, the Leap Operating Companies are in the early stages of developing and
deploying their respective telecommunications systems. Such systems require
significant expenditures, a substantial portion of which is incurred before
corresponding revenues are generated. In addition, the Company and its operating
companies are expected to be highly leveraged which will lead to significant
interest expense and principal repayment obligations. The Company therefore
expects to incur significant expenses in advance of generating revenues and, as
a result, to incur substantial additional losses in the near term. There can be
no assurance that the Company or any of the Leap Operating Companies will
achieve or sustain profitability in the future. Furthermore, there can be no
assurance that the Company will generate sufficient cash flows to meet its debt
obligations or successfully refinance any of its debt at maturity.

     The Company's ability to generate revenues will be dependent on a number of
factors, including the future operations and profitability of its operating
companies. The Leap Operating Companies are expected to incur substantial losses
for the next several years. These operating companies will require substantial
additional financing to build-out and operate their planned networks. If the
Leap Operating Companies do not obtain additional financing in fiscal 2000, Leap
expects that the scope of the planned network build-outs will be reduced. If the
Company is unable to obtain additional working capital or financing, the Company
may have to restrict its activities or sell its interests in one or more
operating companies.




                                       21
<PAGE>   22
There can be no assurance that any of the Leap Operating Companies or any other
companies in which Leap may acquire an interest will be able to obtain the
additional financing they require, or become profitable. The failure of these
companies to build-out their systems, meet their payment obligations or become
profitable would adversely affect the value of the Company's assets and its
future profitability.

    The Company expects to obtain much of its required near-term financing
through borrowings under its secured credit facility with QUALCOMM (the "Credit
Agreement"). The Credit Agreement bears interest at a variable rate, exposing
the Company to interest rate risk. The Company expects that it will have
borrowed substantially all of the funds available to it under the Credit
Agreement by the end of calendar year 2000. As one of the conditions to the
Federal Communications Commission's ("FCC") recognition of the Company's
qualification to hold C-Block and F-Block licenses of PCS spectrum, however, the
Company must take steps so that by January 2001, QUALCOMM holds no more than 50%
of the Company's debt obligations. There can be no assurance that additional
sources of debt financing will be available to the Company to finance its
operations after the Credit Agreement has been fully drawn or to comply with the
condition imposed by the FCC regarding the Company's debt to QUALCOMM. If Leap
fails to meet any of the conditions imposed by the FCC or otherwise fails to
maintain its qualification to own C-Block and F-Block licenses, that failure
would have a material adverse effect on Leap's financial condition and business
prospects.

International Risks

    The Company is subject to numerous risks as a result of its international
activities. The Leap Operating Companies are dependent, in large part, on the
economies of the markets in which they have operations. Those markets and other
markets in which the Company may operate are in countries with economies in
various stages of development, some of which are subject to rapid fluctuations
in currency exchange rates, consumer prices, inflation, employment levels and
gross domestic product. As a result, the Company and the Leap Operating
Companies are exposed to market risk from these changes, and are subject to
other economic and political risks, which could impact their results of
operations and financial condition.

NOTE 2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

    The consolidated financial statements include the accounts of Leap and its
wholly owned and majority owned subsidiaries. All significant intercompany
accounts and transactions have been eliminated in the consolidated financial
statements. Investments in entities, which Leap exercises significant influence,
but does not control, are accounted for using the equity method. In fiscal 1999,
to accommodate the different fiscal periods of the Company and its foreign
operating companies, the Company extended the lag for recognition of its share
of net earnings or losses of such foreign companies from one month to two
months. The effect of this change on previously reported amounts was not
significant.

    For the fourth quarter of fiscal 1999, the financial statements of SMARTCOM
are included in the consolidated financial statements of the Company as a result
of the Company's acquisition of the remaining 50% of SMARTCOM that it did not
already own. The accounts of SMARTCOM have been consolidated using a two-month
lag.

Financial Statement Preparation

    The consolidated financial statements are prepared using generally accepted
accounting principles. These principles require management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities, and the reported amounts of
revenues and expenses. Actual results could differ from those estimates. Certain
prior period amounts have been reclassified to conform to the current period
presentation.

Restatement

    The Company adopted the equity method of accounting for its investment in
Chase in the third quarter of fiscal 1999. Prior to that time, Leap accounted
for its investment in Chase under the cost method. Accordingly, all prior
periods presented in these financial statements have been adjusted retroactively
in accordance with generally accepted accounting principles.

Issuance of Stock by Subsidiaries and Equity Investees

       The Company recognizes gains and losses on issuance of stock by
subsidiaries and equity investees in its Consolidated Statement of Operations
and Comprehensive Loss, except for those subsidiaries and equity investees that
are in the development stage. For those entities in the development stage, gains
and losses are reflected in "effect of subsidiary and unconsolidated wireless
operating company equity transactions" in the Consolidated Statements of
Stockholders' Equity.

Foreign Currency Translation and Transactions

   The Company uses the local currency as the functional currency for all of its
international consolidated and unconsolidated operating companies, except where
such operating companies operate in highly inflationary economies. Assets and
liabilities are translated into U.S. Dollars at the exchange rate in effect at
the balance sheet date. Revenues and expense items are translated at the average
rate prevailing during the period. Resulting unrealized gains and losses are
accumulated and reported as other comprehensive income or loss.

   The functional currency of the Company's foreign investees that operate in
highly inflationary economies is the U.S. Dollar. The monetary assets and
liabilities of these foreign investees are re-measured into U.S. Dollars at the
exchange rate in effect at the balance sheet date. Revenues, expenses, gains and
losses are translated at the average exchange rate for the period, and
non-monetary assets and liabilities are translated at historical rates.

   Resulting re-measurement gains or losses of foreign investees are recognized
in the results of operations.

   Mexico ceased to be considered a highly inflationary economy as of January 1,
1999 and, as a result, PEGASO changed its functional currency from the U.S.
Dollar to its local currency on that date.

Cash and cash equivalents

    The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. At August 31, 1999, the
Company's cash and cash equivalents consisted of deposits with banks and
investments in money market accounts and mutual funds. The Company has not
experienced any losses on its deposits of cash and cash equivalents.



                                       23

Fair Value of Financial instruments

    The carrying amounts of certain of the Company's financial instruments,
including cash equivalents, accounts receivable, recoverable taxes and accounts
payable approximate fair value due to their short-term maturities. Loans payable
to banks and other long-term debts approximate fair value due to their risk
adjusted market rates of interest.

Accounts Receivable

    The Company's trade accounts receivable are derived from revenue earned from
customers located in Chile and are denominated in Chilean pesos. The Company
records an allowance for uncollectable accounts receivable with respect to those
amounts estimated not to be recoverable.

Inventories

    Inventories consist of handsets and accessories not yet placed into
service and are stated at the lower of cost or market. The Company uses the
first-in, first-out method of determining inventory cost.

Recoverable Taxes

    Recoverable taxes relate to value added taxes (VAT) incurred on the supply
of goods and services which, are eventually borne by the final consumer. VAT
payments made by the Company on the build-out of its wireless communications
networks are recovered in cash from customers as services are provided.

Investments in Unconsolidated Wireless Operating Companies

   The Company uses the equity method to account for investments in corporate
entities in which it exercises significant influence, but does not control.
Under the equity method, the investment is originally recorded at cost and
adjusted to recognize the Company's share of net earnings or losses of the
investee, limited to the extent of the Company's investment in, advances to and
financial guarantees for the investee. Such earnings or losses of the Company's
investees are adjusted to reflect the amortization of any differences between
the carrying value of the investment and the Company's equity in the net assets
of the investee. For those unconsolidated subsidiaries where the Company is the
only contributor of assets, equity in net losses of wireless operating companies
includes 100% of the losses of the equity investee.

Property and equipment

    Property and equipment are recorded at cost. Constructed assets are recorded
at cost plus capitalized interest and direct costs incurred during the
construction phase. Depreciation is applied using the straight-line method over
the estimated useful lives of the assets, ranging from two to ten years, once
the assets are placed in service. Leasehold improvements are amortized over the
shorter of their estimated useful lives or the remaining term of the related
lease. Repairs and maintenance costs are expensed as incurred.

Intangible Assets

    Intangible assets, primarily telecommunications licenses and rights to
telecommunications network systems, are recorded at cost and amortized over
their estimated useful lives upon commencement of commercial service, which
currently range from ten to twenty-eight years.



                                       24
<PAGE>   25

Long-Lived Assets

   The Company reviews long-lived assets and certain identifiable intangibles
for impairment whenever events or changes in circumstances indicate that the
total amount of an asset may not be recoverable. An impairment loss is
recognized when estimated future cash flows expected to result from the use of
the asset and its eventual disposition are less than its carrying amount.

Debt Discount and Facility Fees

    Debt discount and facility fees are amortized and recognized as interest
expense under the interest method.

Revenue recognition

    Operating revenues are recognized as telecommunications services are
rendered and as handsets and other products are delivered to customers.

Stock-based Compensation

    The Company measures compensation expense for its employee and outside
directors stock-based compensation using the intrinsic value method.
Compensation charges related to non-employee stock-based compensation are
measured using the fair value method.

Income Taxes

   Current income tax benefit (expense) is the amount expected to be receivable
(payable) for the current year. A deferred tax asset and/or liability is
computed for both the expected future impact of differences between the
financial statement and tax bases of assets and liabilities and for the expected
future tax benefit to be derived from tax loss and tax credit carry forwards.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amount expected to be "more likely than not" realized in future
tax returns. Tax rate changes are reflected in income in the period such changes
are enacted.

Reporting Comprehensive Income (Loss)

    Effective September 1, 1998, the Company adopted the provisions of Financial
Accounting Standards Board ("FASB") Statement of Financial Accounting Standards
("SFAS") No. 130, "Reporting Comprehensive Income." This statement requires the
Company to report in its financial statements, in addition to net income (loss),
comprehensive income (loss) and its components, including foreign currency
translation gains (losses). Prior period financial statements have been adjusted
to conform to the requirements of SFAS No. 130.

Basic and Diluted Net Loss Per Common Share

    Basic and diluted net loss per common share for the years ended August 31,
1999, 1998 and 1997 was calculated by dividing the net loss for each of the
periods by the weighted average number of common shares outstanding for each of
the periods of 17,910,440, 17,647,685 and 17,647,685, respectively. The weighted
average number of common shares outstanding assumes that the 17,647,685 shares
issued at Distribution were outstanding for the periods prior to Distribution.
Stock options for 5,939,715 common shares, the conversion of QUALCOMM's Trust
Convertible Preferred Securities which are convertible into 2,270,573 shares of
the Company's common stock, and the exercise of a warrant issued to QUALCOMM for
4,500,000 shares of the Company's common stock have not been considered in
calculating basic and diluted net loss per common share because their effect
would be anti-dilutive. As a result, the Company's basic and diluted net loss
per common share are the same.



                                       25
<PAGE>   26

Segment Reporting

    Effective September 1, 1998, the Company adopted SFAS No. 131, "Disclosures
about Segments of an Enterprise and Related Information." SFAS No. 131 adopts
the management approach which designates internal reporting used by management
for making operating decisions and assessing performance as the source of the
Company's reportable segments. SFAS No. 131 also requires disclosures about
products and services, geographic areas and major customers. The adoption of
SFAS No. 131 did not affect results of operations or the financial position of
the Company but did affect the disclosure of segment information.

Future Accounting Requirements

   In April 1998, the Accounting Standards Executive Committee issued Statement
of Position ("SOP") No. 98-5, "Reporting on the Costs of Start-Up Activities",
which the Company will be required to adopt for fiscal year 2000. This SOP
provided guidance on the financial reporting of start-up and organizational
costs. It requires start-up and organizational costs to be expensed as incurred.
The Company does not expect that the adoption of SOP No. 98-5 will have a
material impact on its consolidated financial position or results of operations.

       In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which the Company will be required to adopt
for fiscal year 2001. This statement establishes a new model for accounting for
derivatives and hedging activities. Under SFAS No. 133, all derivatives must be
recognized as assets and liabilities and measured at fair value. The Company
does not expect that the adoption of SFAS No. 133 will have a material impact on
its consolidated financial position or results of operations.

NOTE 3. ACQUISITIONS AND DISPOSALS

SMARTCOM

   In April 1999, Leap acquired the remaining 50% of SMARTCOM that it did not
already own from Telex-Chile S.A. and its operating affiliate, Chilesat S.A.
(collectively "Telex-Chile"). In exchange, the Company paid $28 million in cash
and issued a $22 million, non-interest-bearing note payable to Telex-Chile due
in May 2002. The present value of the $22 million non-interest-bearing note
payable to Telex-Chile was $15.7 million upon issuance. Therefore, the total
purchase price was $43.7 million. The Company accounted for the transaction as a
purchase and allocated the $40.8 million excess investment over the fair value
of the net assets acquired to intangible assets, which include
telecommunications licenses and rights to telecommunications network systems.

    The following unaudited pro forma information presents the results of
operations of the Company as if the acquisition had taken place on September 1,
1997 (in thousands, except per share data):

    These unaudited pro forma amounts are for comparative purposes only and do
not necessarily represent what actual results of operations would have been had
the acquisition occurred on September 1, 1997, nor do they necessarily indicate
results of future operations.

Licenses

       In September 1998, the Company agreed to purchase four wireless
communications licenses from AirGate Wireless, L.L.C. ("AirGate") for $19.5
million, paying a deposit of $0.6 million.

    In July 1999, the FCC issued a Memorandum Opinion and Order that found the
Company was qualified to hold C-Block and F-Block PCS licenses in the United
States. The order also approved the Company's $18.7 million cash acquisition of
36 wireless communications licenses in the U.S. government's April 1999
reauction of PCS spectrum and approved the transfer of the four licenses from
AirGate to the Company. The FCC order was subject to several conditions,
including the Company taking steps so that by January 2001, QUALCOMM holds no
more than 50% of Leap's outstanding debt obligations.

OzPhone

    In June 1998, the Company purchased all the shares of OzPhone, an Australian
company, for $564,000. The entire purchase price was allocated to goodwill.
OzPhone then acquired several wireless communications licenses to provide mobile
and wireless local loop services in Australia. The total cost of the licenses
was $6.3 million. In August 1999, the Company sold all of the shares of OzPhone
for $16.0 million in cash and recorded a gain of $9.1 million.


NOTE 4.  INVESTMENTS AND LOANS TO WIRELESS OPERATING COMPANIES

    The Company has equity interests in companies that directly or indirectly
hold wireless communications licenses. Its participation in each company differs
and, except for SMARTCOM for the fourth quarter of fiscal 1999, the Company does
not have majority interests in such companies. The Company accounts for these
equity interests, except for SMARTCOM, under the equity method. For the fourth
quarter of fiscal 1999, the financial statements of SMARTCOM have been
consolidated. The Company's ability to withdraw funds, including dividends, from
its participation in such investments is dependent in many cases on receiving
the consent of lenders and the other participants, over which the Company has no
control. The Company and its consolidated subsidiaries have investments in
wireless operating companies consisting of the following:

Chase

    In December 1996, the Company purchased $4.0 million of Class B Common Stock
of Chase, representing 7.2% of the outstanding capital stock of Chase. The
Company has also provided a working capital facility to Chase and has agreed in
principle to increase the maximum principal that may be drawn to $45.0 million.
Borrowings under the facility are subject to interest at an annual rate of prime
plus 4.5%. Semi-annual principal payments are to be made ratably over a six-year
period commencing June 2000, with accrued interest payable on maturity.
Borrowings are collateralized by substantially all of the assets of Chase and
are subordinated to Chase's equipment vendor loans from QUALCOMM. At August 31,
1999, borrowings under the facility totaled $36.1 million, including $3.3
million of accrued and capitalized interest. However, because the working
capital facility is the only source of working capital for Chase, the carrying
value of its investment and the loans under the facility have been reduced to
zero as Leap has recognized 100% of the net losses of Chase to the extent of its
investment and loans. The Company



                                       28
<PAGE>   29

recorded equity losses from Chase of $20.9 million, $11.8 million and $4.0
million during fiscal 1999, 1998 and 1997, respectively.

    In December 1998, the Company agreed to purchase substantially all the
assets of Chase for $6.3 million; a warrant to purchase 1% of the common stock
of Cricket Communications, Inc. ("Cricket Communications"), a majority-owned
subsidiary of the Company, exercisable at $1.0 million; the Company's existing
stock ownership and warrants to purchase stock in Chase; and certain contingent
earn-outs. This acquisition involves the transfer of wireless communications
licenses, which is subject to approval by the FCC. The acquisition will not
occur unless the FCC approves the transfer of the licenses.

    In April 1999, Leap acquired the remaining 50% of SMARTCOM that it did not
already own. As a result of the reporting lag, the Company began fully
consolidating SMARTCOM's results of operations commencing June 1, 1999. Prior to
this time, the Company accounted for its investment in SMARTCOM under the equity
method of accounting. The Company recorded equity (income) losses from SMARTCOM
of $13.1 million, $3.1 million and $(0.2) million during fiscal 1999, 1998 and
1997, respectively.

PEGASO

    The Company has a 28.6% interest in PEGASO, a Mexican corporation. During
fiscal 1998, the Company advanced a portion of PEGASO's working capital
requirements and provided a loan of $27.4 million to PEGASO. The purpose of the
loan was to fund a portion of PEGASO's first PCS license payment. Interest on
the loan accrued at a rate of 10% and was added to the principal amount of the
loan outstanding. In September 1998, the Company provided $60.7 million of
additional funding and converted its advances and loan, with accrued interest,
into capital stock of PEGASO. The Company's total investment in PEGASO after
these transactions was $100.0 million. On the same date, other investors also
subscribed for and purchased capital stock of PEGASO such that, after these
transactions, the total par value of the common equity of PEGASO was $300
million. As a result, the Company's ownership interest in PEGASO was diluted
from 49.0% to 33.3%. In July 1999, several of the other investors subscribed for
and purchased an additional $50.0 million of capital stock of PEGASO. As a
result, the Company's ownership interest was diluted from 33.3% to 28.6%. The
Company recorded equity losses from PEGASO of $23.6 million and $2.1 million
during fiscal 1999 and 1998, respectively. In fiscal 1999, the Company
recognized a gain of $4.4 million on the issuance of stock by PEGASO as
described above. Of this amount, $0.8 million was recognized directly to
additional paid-in capital for the change in interest that occurred during
PEGASO's development stage.

Metrosvyaz

    The Company has a 35% interest in Metrosvyaz. The Company agreed to provide
a $72.5 million loan facility to Metrosvyaz to support its business plan and
working capital needs. Metrosvyaz also has a $102.5 million equipment loan
facility from QUALCOMM. The Company has pledged its equity interest in
Metrosvyaz as collateral for amounts owed under QUALCOMM's loan facility to
Metrosvyaz, and has subordinated its $72.5 million loan facility to QUALCOMM's
$102.5 million loan facility. Borrowings under the $72.5 million facility are
subject to interest at 13% and are due in August 2007. Interest is payable
semi-annually beginning August 2000 and, prior to such time, added to the
principal amount outstanding. At August 31, 1999, borrowings under the Company's
loan facility to Metrosvyaz totaled $39.5 million, including $2.7 million of
accrued and capitalized interest and $1.1 million of facility fees.

    The Company's investment in Metrosvyaz consists of the outstanding loan
facility, less its share of equity losses. The Company recorded equity losses of
$20.0 million from Metrosvyaz in fiscal 1999. In

addition, the Company stopped funding Metrosvyaz and recorded a write-down of
$9.6 million, the Company's remaining investment in Metrosvyaz, in the fourth
quarter. The Company recorded equity losses from Metrosvyaz of $6.1 million
during fiscal 1998.

Orrengrove

    The Company has a 35% interest in Orrengrove. In August 1998, Orrengrove
acquired a 60% interest in Transworld Telecommunications, Inc., Transworld
Communications Services, Inc., and Transworld Communications (Bermuda), Ltd.
(collectively, the "Transworld Companies").

    The Transworld Companies obtained, through a number of agreements, the
rights to utilize the capacity on certain Russian satellites in order to provide
commercial long-distance voice, video and data services to the Russian
Federation. In April 1999, the Transworld Companies were notified by Mercury
Telesat ("Mercury"), provider of the satellite signal transmission capacity,
that the satellite equipment used to provide their long-distance service had
failed. Mercury's prognosis indicated that the satellite's operational status
will not be restored. The Transworld Companies identified and put into operation
a short-term terrestrial transmission solution by leasing fiber capacity and
began exploring long-term alternatives to the lost satellite transmission
capacity. As a result of these events, Orrengrove recognized an impairment loss
of approximately $16.9 million in the third quarter of fiscal 1999 to write off
certain satellite related assets. This loss is included in the Company's equity
in net loss from unconsolidated wireless operating companies.

    After reviewing a series of alternative business plans that did not meet
their minimum financial performance criteria, the directors of the Transworld
Companies voted to liquidate those companies and to distribute the net assets to
their stockholders. As a result, the Company recorded a $17.6 million write-down
in the fourth quarter of fiscal 1999, reducing its investment in Orrengrove to
the liquidation proceeds Leap expects to receive. In addition, the Company
recorded equity losses of $22.6 million from Orrengrove during fiscal 1999,
which included the write-off of the satellite related assets and impairment of
the license.

</TABLE>

Credit Agreement

    The Company entered into a secured Credit Agreement with QUALCOMM on
September 23, 1998. The Credit Agreement consists of two sub-facilities. The
working capital sub-facility enables the Company to borrow up to $35.2 million
from QUALCOMM. The proceeds from this sub-facility may be used by the Company
solely to meet the normal working capital and operating expenses of the Company,
including salaries and overhead, but excluding, among other things, strategic
capital investments in wireless operators, substantial acquisitions of capital
equipment, and the acquisition of telecommunications licenses. The investment
capital sub-facility enables the Company to borrow up to $229.8 million from
QUALCOMM. The proceeds from this second sub-facility may be used by the Company
solely to make certain identified investments. Under the terms of the Credit
Agreement, if QUALCOMM assigns 10% or more of the total funding commitments to
other lenders, Leap must pay a commitment fee to the lenders on unused balances.

    At August 31, 1999, the Company had borrowed $10.6 million under the working
capital sub-facility, including $5.3 million to pay QUALCOMM a 2% facility fee
which is being amortized over the term of the Credit Agreement ($0.6 million of
the facility fee was amortized in 1999). At August 31, 1999, the Company had
borrowed $108.8 million under the investment capital sub-facility to make
further loans to and investments in the Leap Operating Companies.

    Amounts borrowed under the Credit Agreement are due September 23, 2006.
QUALCOMM has a collateral interest in substantially all of the assets of the
Company as long as any amounts are outstanding under the Credit Agreement. The
Credit Agreement requires the Company to meet certain financial and operating
covenants. Amounts borrowed under the Credit Agreement bear interest at either a
prime or LIBOR rate, plus an applicable margin. At August 31, 1999, the
weighted average effective rate of interest was 11.35%. Interest will be payable
quarterly beginning after September 2001 and, prior to such time, accrued
interest will be added to the principal amount outstanding. At August 31, 1999,
$5.5 million of capitalized and accrued interest had been added to the Credit
Agreement.

Deferred Payment Agreement

    SMARTCOM and QUALCOMM are parties to a Deferred Payment Agreement related to
SMARTCOM's purchase of equipment, software and services from QUALCOMM. The
assets of SMARTCOM collateralize its obligations under the Deferred Payment
Agreement. The Company has also pledged its shares in SMARTCOM as collateral for
the Company's guaranty of SMARTCOM's obligation to QUALCOMM. The Deferred
Payment Agreement requires SMARTCOM to meet certain financial and operating
covenants, including a debt to equity ratio and restrictions on SMARTCOM's
ability to pay dividends and to distribute assets. As a result, substantially
all the net assets are restricted from distribution to Leap. SMARTCOM was in
violation of certain covenants at August 31, 1999, however QUALCOMM and SMARTCOM
amended the Deferred Payment Agreement subsequent to the end of the fiscal year
to revise the covenants that were in default and defer the dates of repayment of
the loan.


                                       32
<PAGE>   33

    Under the terms of the amended agreement, QUALCOMM has agreed to defer
collection of amounts up to a maximum of $84.5 million. The deferred payments
bear interest at either a prime or LIBOR rate, plus an applicable margin. At
August 31, 1999, the weighted average effective rate of interest was 8.2%.
Accrued interest may be added to the outstanding principal amount of the
applicable borrowing until October 2001.

    Management has established a valuation allowance against its deferred tax
assets due to the uncertainty surrounding the realization of such assets.

    The net operating losses generated prior to the Distribution were retained
by QUALCOMM. At August 31, 1999 the Company had a federal net operating loss
carryover of approximately $86.0 million which will expire in 2019. In addition,
the Company had foreign net operating losses of approximately $52.5 million
which do not expire. Should a substantial change in the Company's ownership

NOTE 10. STOCKHOLDERS' EQUITY

Stockholder Rights Plan

    In September 1998, the Company's Board of Directors adopted a Stockholder
Rights Plan (the "Rights Plan"). Pursuant to the Rights Plan, the Board of
Directors declared a dividend, payable on September 16, 1998, of one preferred
purchase right (a "Right") for each share of common stock, $.0001 par value, of
the Company outstanding at the close of business on September 11, 1998. Similar
Rights will generally be issued in respect to common stock subsequently issued.
Each Right entitles the registered holder to purchase from the Company a one
one-thousandth share of Series A Junior Participating Preferred Stock, $.0001
par value per share, at a purchase price of $90 (subject to adjustment). The
Rights are exercisable only if a person or group (an "Acquiring Person"), other
than QUALCOMM with respect to its exercise of the warrant granted to it in
connection with the Distribution, acquires beneficial ownership of 15% or more
of the Company's outstanding shares of common stock. Upon exercise, holders
other than an Acquiring Person, will have the right (subject to termination) to
receive the Company's common stock or other securities having a market value (as
defined) equal to twice the purchase price of the Right. The Rights, which
expire on September 10, 2008, are redeemable in whole, but not in part, at the
Company's option at any time for a price of $.01 per Right.

    In conjunction with the distribution of the Rights, the Company's Board of
Directors designated 75,000 shares of Preferred Stock as Series A Junior
Participating Preferred Stock and reserved such shares for issuance upon
exercise of the Rights. At August 31, 1999, no shares of Preferred Stock were
outstanding.

Warrant

    In connection with the Distribution, the Company issued QUALCOMM a warrant
to purchase 5,500,000 shares of the Company's common stock. In March 1999,
QUALCOMM agreed to reduce the number of shares to 4,500,000 for consideration of
$5.4 million, which is the estimated fair value of the warrant repurchase as
determined by an option pricing model. This warrant is currently



                                       34
<PAGE>   35

exercisable and remains exercisable until September 2008.

Trust Convertible Preferred Securities

    Under the conversion agreement between the Company and QUALCOMM, Leap has
agreed to issue up to 2,271,060 shares of its common stock upon the conversion
of the Trust Convertible Preferred Securities of a wholly owned statutory
business trust of QUALCOMM. After conversion of the Trust Convertible Preferred
Securities, QUALCOMM will have some of its debt reduced, but Leap will receive
no additional benefit or other consideration. At August 31, 1999, 487 shares of
the Company's common stock had been issued upon conversion.

NOTE 11. BENEFIT PLANS

Employee Savings and Retirement Plan.

   In September 1998, the Company adopted a 401(k) plan that allows eligible
employees to contribute up to 15% of their salary, subject to annual limits. The
Company matches a portion of the employee contributions and may, at its
discretion, make additional contributions based upon earnings. The Company's
contribution expense for fiscal 1999 was $133,000.

Stock Option Plans

   In September 1998, the Company adopted the 1998 Stock Option Plan (the "1998
Plan") that allows the Board of Directors to grant options to selected
employees, directors and consultants to the Company to purchase shares of the
Company's common stock. A total of 8,000,000 shares of common stock were
reserved for issuance under the 1998 Plan. The 1998 Plan provides for the grant
of both incentive and non-qualified stock options. Incentive stock options are
exercisable at a price not less than 100% of the fair market value of the common
stock on the date of grant. Non-qualified stock options are exercisable at a
price not less than 85% of the fair market value of the common stock on the date
of grant. Generally, options vest over a five-year period and are exercisable
for up to ten years from the grant date. The Company also adopted the 1998
Non-Employee Directors Stock Option Plan (the "1998 Non-Employee Directors
Plan"), under which options to purchase common stock are granted to non-employee
directors on an annual basis. A total of 500,000 shares of common stock were
reserved for issuance under the 1998 Non-Employee Directors Plan. The options
are exercisable at a price equal to the fair market value of the common stock on
the date of grant, vest over a five-year period and are exercisable for up to
ten years from the grant date.

   In June 1999, Cricket Communications adopted its own 1999 Stock Option Plan
(the "1999 Cricket Plan") that allows the Cricket Communications Board of
Directors to grant options to selected employees, directors and consultants to
purchase shares of Cricket Communication's common stock. A total of 7,600,000
shares of Cricket Communications common stock were reserved for issuance under
the 1999 Cricket Plan. The 1999 Cricket Plan provides for the grant of both
incentive and non-qualified stock options. Incentive stock options are
exercisable at a price not less than 100% of the fair market value of the
Cricket Communications common stock on the date of grant. Non-qualified stock
options are exercisable at a price not less than 85% of the fair market value of
the Cricket Communications common stock on the date of grant. Generally, options
vest over a five-year period and are exercisable for up to ten years from the
grant date. In June 1999, a total of 1,205,000 options to purchase Cricket
Communications common stock were granted to two directors of the Company,
exercisable at $1.00 per share with accelerated vesting provisions. In July
1999, all of these options vested and were fully exercised. In addition, 795,000
other options granted in June 1999 were exercised in July 1999. Cricket
Communications received promissory notes totaling $0.9 million and cash of $1.1
million in consideration for the issuance of the shares. Immediately thereafter,
the Company owned 96.2% of the outstanding common stock of Cricket
Communications. As Cricket Communications is in the development stage, the
effect of the issuance of the shares of $0.6 million has been recorded to
additional paid-in capital. These transactions in fiscal 1999 have been
reflected in minority interest.

Employee Stock Purchase Plan

   In September 1998, the Company adopted the 1998 Employee Stock Purchase Plan
(the "1998 ESP Plan") for all eligible employees to purchase shares of common
stock at 85% of the lower of the fair market value of such stock on the first or
the last day of each offering period. A total of 200,000 shares of common stock
were reserved for issuance under the 1998 ESP Plan. Employees may authorize the
Company to withhold up to 15% of their compensation during any offering period,
subject to certain limitations. During fiscal 1999, a total of 63,779 shares
were issued under the 1998 ESP Plan at $3.83 per share. At August 31, 1999,
136,221 shares were reserved for future issuance.

Executive Retirement Plan

   In September 1998, the Company adopted a voluntary retirement plan that
allows eligible executives to defer up to 100% of their income on a pre tax
basis. On a quarterly basis, participants receive up to a 10% match of their
deferral in the form of the Company's common stock based on the then current
market price, to be issued to the participant upon eligible retirement. The
income deferred and the Company match are unsecured and subject to the claims of
general creditors of the Company. The plan authorizes up to 100,000 shares of
common stock to be allocated to participants. During fiscal 1999, 8,718 shares
were allocated under the plan and the Company's matching contribution amounted
to $86,216. At August 31, 1999, 91,282 shares were reserved for future
allocation.

Accounting for Stock-Based Compensation

    Pro forma information regarding net income (loss) and net earnings (loss)
per common share is required by SFAS No. 123, "Accounting for Stock-Based
Compensation". This information is required to be determined as if the Company
had accounted for its stock-based awards to employees and non-employee directors
(including shares issued under stock options and the 1998 ESP Plan, collectively
called "options") granted subsequent to September 30, 1995 under the fair value
method of SFAS No. 123. The fair value of options granted in fiscal 1999
reported below has been estimated at the date of grant using the Black-Scholes
option-pricing model using the following weighted average assumptions:

    The Black-Scholes option-pricing model was developed for use in estimating
the fair value of traded options that have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions, including the expected stock price volatility. Because
the Company's options have characteristics significantly different than those of
traded options, and because changes in the subjective input assumptions can
materially affect the fair value estimate, in the opinion of management, the
existing models do not necessarily provide a reliable single measure of the fair
value of its options. The weighted average estimated grant date fair values of
stock options granted in fiscal 1999 under the 1998 Plan, the 1999 Cricket Plan
and the 1998 ESP Plan were $2.37, $0.12 and $2.37 per share, respectively.

    For purposes of pro forma disclosures, the estimated fair value of the
options is assumed to be amortized to expense over the options' vesting period.
The Company's pro forma information for the year ended August 31, 1999 is as
follows (in thousands, except per share data):

    The Company did not recognize a tax benefit relating to pro forma
compensation expense under SFAS No. 123 for fiscal 1999 as such benefit did not
meet the "more likely than not" criteria for recognition of deferred tax assets.

NOTE 12.   COMMITMENTS AND CONTINGENCIES

    In May 1999, PEGASO entered into a $100 million loan agreement. The Company
guaranteed 33% of PEGASO's obligations under this loan agreement in the event
of PEGASO's default.

   The Company has entered into non-cancelable operating lease agreements to
lease its facilities, certain equipment and rental of sites for towers and
antennas required for the operation of its mobile PCS telephone system in Chile.
Future minimum rental payments required for all non-cancelable operating leases
at August 31, 1999 are as follows (in thousands):

    Rent expense totaled $1.2 million in fiscal 1999. No rent expense was
incurred by the Company prior to the Distribution.

    Various claims arising in the course of business, seeking monetary damages
and other relief, are pending. The amount of the liability, if any, from such
claims cannot be determined with certainty; however, in the opinion of
management, the ultimate liability for such claims will not have a material
adverse effect on the Company's consolidated financial position, results of
operations or cash flows.

NOTE 13. SEGMENT DATA

    The Company's current reportable segments are countries in which it manages,
supports, operates and otherwise participates in wireless communications
business ventures. These reportable segments are evaluated separately because
each geographic region presents different marketing strategies and operational
issues, as well as distinct economic climates and regulatory constraints. The
Company's reportable segments are comprised of Cricket Communications and Chase
in the United States, and Leap's operating companies in Mexico and Chile.

    The accounting policies of the various segments are the same as those
described in Note 2, "Summary of Significant Accounting Policies". The key
operating performance criteria used by Leap includes revenue growth, operating
income (loss), depreciation and amortization, capital expenditures, and
purchases of wireless licenses. Segment assets exclude corporate assets.
Corporate expenses are comprised primarily of general and administrative
expenses, which are separately managed. The segment results of Chile and Mexico
do not include any corporate allocations of general and administrative expenses
from Leap.

NOTE 14. SUBSEQUENT EVENTS

Infrastructure Agreements

    In September 1999, a subsidiary of Leap entered into separate infrastructure
equipment purchase agreements with two major telecommunications suppliers. Under
the agreements, each supplier will sell $330 million in infrastructure equipment
to the subsidiary. In connection with the sales of infrastructure equipment, the
suppliers will provide vendor financing that will be used for equipment,
services and operations needed to deploy the subsidiary's wireless networks in
various markets across the United States. One of the purchase agreements is
subject to the approval of the applicable supplier's board of directors.

                       Report of Independent Accountants


To the Board of Directors and Stockholders
     of Leap Wireless International, Inc.:


In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations and comprehensive loss, of cash flows and
of stockholders' equity present fairly, in all material respects, the financial
position of Leap Wireless International, Inc. and its subsidiaries at August 31,
1999 and 1998, and the results of their operations and their cash flows for each
of the three years in the period ended August 31, 1999 in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards, which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

As discussed in Note 2 to the consolidated financial statements, the Company
adopted the equity method of accounting for its investment in Chase
Telecommunications Holdings, Inc. during the year ended August 31, 1999. The
accompanying financial statements have been restated to reflect the adoption of
the equity method retroactive to the initial date of the Company's investment in
Chase Telecommunications Holdings, Inc.
