ITEM 1. BUSINESS
 
     All statements contained herein that are not historical facts, including
but not limited to, statements regarding the Company's plans for future
development and operation of its business, are based on current expectations.
These statements are forward looking in nature and involve a number of risks and
uncertainties. Actual results may differ materially. Among the factors that
could cause actual results to differ materially are the following: a lack of
sufficient capital to finance the Company's business plan on terms satisfactory
to the Company; pricing pressures which could affect demand for the Company's
service; changes in labor, equipment and capital costs; unavailability of
digital compression technology and equipment at reasonable prices; the Company's
inability to incorporate digital compression technology into certain of its
subscription television systems in a cost efficient manner; the Company's
inability to develop and implement new services such as high-speed Internet
access and telephony; the Company's inability to obtain the necessary
authorizations from the Federal Communications Commission ("FCC") for such new
services; competitive factors, such as the introduction of new technologies and
competitors into the wireless communications business; a failure by the Company
to attract strategic partners; general business and economic conditions; and the
other risk factors described from time to time in the Company's reports filed
with the Securities and Exchange Commission ("SEC"). The Company wishes to
caution readers not to place undue reliance on any such forward looking
statements, which statements are made pursuant to the Private Securities
Litigation Reform Act of 1995, and as such, speak only as of the date made.
 
GENERAL
 
     American Telecasting, Inc. ("ATI" or the "Company") was formed in 1988 to
develop wireless cable television systems in mid-sized markets throughout the
United States. As of December 31, 1996, the Company provided subscription
television service to approximately 179,800 subscribers through 38 operational
wireless cable systems located in selected U.S. markets (the "Developed
Markets"). The Company also has significant wireless cable (microwave) frequency
interests in 16 other U.S. markets (the "Undeveloped Markets" and together with
the Developed Markets, the "Markets"). As of December 31, 1996, the Company had
approximately 12.0 million Estimated Households in Service Area in its Markets,
although some of these households will be "shadowed" and unable to receive the
services offered by the Company due to certain characteristics of the particular
market, such as transmitter height and transmission power, terrain and foliage
("Line-of-Sight Constraints"). See "-- Markets".
 
     Wireless cable systems use microwave frequencies licensed by the FCC to
transmit signals over the air from a transmission tower to a microwave receiver
installed at the customer's home or business. Wireless cable systems transmit
signals over coverage areas of approximately 20 to 40 miles from their central
transmission point, although increases in transmission power and other factors
may expand the coverage area of a system to approximately 40 to 50 miles from
the central transmission point. Because microwave signals are transmitted over
the air, wireless cable technology does not require the large networks of cable
and amplifiers utilized by franchise cable operators to deliver services. Thus,
wireless cable technology has been developed as a reliable, yet relatively low
cost medium to provide service to customers in single family homes, multiple
dwelling units and commercial properties.
 
     The Company was incorporated in Delaware in December 1988 and has its
principal executive offices at 5575 Tech Center Drive, Suite 300, Colorado
Springs, Colorado 80919. The Company's telephone number is (719) 260-5533. The
Company operates its business through its subsidiaries. Except as otherwise
indicated, references in this Report to "ATI" or the "Company" refer to American
Telecasting, Inc. and its subsidiaries collectively.
 
BUSINESS STRATEGY
 
     Since inception, the Company has focused principally on developing wireless
cable systems to provide multiple channel television programming similar to that
offered by franchise cable companies. The Company's
<PAGE>   3
 
primary strategy has been to develop systems in mid-sized markets where terrain
and other conditions are well suited to wireless cable service. To attract
subscribers in these markets, the Company has sought to exploit the cost
advantage that wireless cable has over other subscription television services by
offering the most popular programming (including "basic" channels such as ESPN,
CNN, USA Network, Nickelodeon, Discovery, regional sports channels, MTV, local
broadcast channels, and one to three "premium" channels such as Home Box Office,
Showtime and The Disney Channel) at affordable prices and by emphasizing a
strong commitment to customer service. In developing and implementing its
business strategy, the Company also has sought to maintain the flexibility to
adapt to new technologies such as digital compression and interactive services.
 
     During 1996, the Company's business strategy evolved to adapt to the
significant regulatory and technological changes that have occurred recently in
the telecommunications industry and to the Company's capital constraints. See
"-- Regulation" and "-- Competition." Since early 1996 the Company has taken
certain actions aimed at reducing its costs and conserving its capital,
including reductions in the size of the Company's workforce and decreases in
capital expenditures and discretionary expenses. Management now believes that
the most promising use of the Company's wireless assets may be to provide a
variety of digital wireless services, instead of the traditional analog-based
technology utilized by the Company to date. Such digital wireless services could
include digital video (i.e., subscription television), high-speed Internet
access, and telephony services. A successful deployment of such services might
include the full bundle of broad band (i.e., video and high-speed Internet) and
narrow band (i.e., telephony) services.
 
  Digital Video Service
 
     Digital video is capable of delivering a significantly expanded number of
high quality channels of compressed video programming services, including
off-air programming. Digital compression allows the capacity of each wireless
cable channel to increase by four to ten times. The first fully operational
commercial microwave digital video system in North America was launched in
Canada in late 1996. To date, no wireless cable operator has commercially
introduced digital video compression technology in the United States, although a
number of wireless cable operators, including the Company, have successfully
tested such technology in their systems and have announced various plans for
commercial deployment. While management believes that the Company is generally
prepared for the introduction of digital video compression in certain of its
markets, the purchase of digital video compression transmission and receiving
equipment would involve substantial capital expenditures, which the Company is
not in a position to make at this time. In addition, although the FCC generally
authorized the use of digital technologies in 1996, further specific
authorizations must be obtained from the FCC and affected FCC licensees and
applicants on a market-by-market basis in order for the Company to begin
offering digital video service. See "-- Regulation." To the extent that the
Company is able to implement digital compression technology in any of its
markets, management anticipates that this expanded channel capacity will
increase the Company's opportunities to compete with other providers of video
services. In addition, the application of digital compression may result in the
availability of channel capacity for other services, as described below.
 
  High-Speed Internet Access Service
 
     The Company is working to deploy high-capacity, high-speed Internet access
service in certain of its markets. During 1996, the Company, along with other
industry participants, successfully tested a two-way wireless Internet
technology at the Company's Lakeland, Florida system using existing transmission
and reception equipment. This test confirmed that wireless cable frequencies are
capable of delivering two-way Internet access at speeds that are significantly
faster than speeds commonly available using conventional telephone lines.
However, before the Company may begin offering two-way Internet access on a
commercial basis, it must secure certain regulatory approvals from the FCC. The
Company, together with other wireless cable operators, petitioned the FCC in
March 1997 to expand its digital authorizations to permit two-way transmission.
See "-- Regulation."
 
     Prior to any two-way authorization, the Company intends to deploy an
asymmetrical (i.e., one-way) high-speed Internet access service in its Colorado
Springs, Colorado system during the second quarter of 1997.
 
                                        2
<PAGE>   4
 
This technology utilizes a high-speed wireless cable modem for downstream
Internet access, while relying on a telephone line for upstream Internet access.
The Company's plan in deploying a one-way high-speed Internet service in
Colorado Springs is to establish the commercial viability of its service by
confirming the reliability and performance of the technologies involved and
exploring the level of customer demand for such service. Based upon the
Company's experience in Colorado Springs, available capital and other factors,
it will consider a broader deployment of commercial Internet services in other
markets.
 
  Telephony Service
 
     The Company is considering using its wireless spectrum to deliver telephony
services. Although the development of such telephony services is in its early
stages, management believes that the Company's wireless spectrum may be capable
of providing "local loop" telephone service in the future.
 
     While the Company intends to continue its development efforts with respect
to local loop telephone service, the introduction of such service in any of the
Company's markets would involve substantial capital expenditures, which the
Company is not in a position to make at this time. The Company's ability to
commence delivery of wireless local loop service will also depend upon
successful development of wireless local loop technology and equipment and the
availability of appropriate transmission and reception equipment on satisfactory
terms. Regulatory approvals and changes, especially routine two-way licensing of
the radio spectrum used by the Company, also would be required before the
Company could commercially introduce local loop telephone service. See
"-- Regulation."
 
CERTAIN REQUIREMENTS AND UNCERTAINTIES
 
     While the Company has begun planning and testing of the digital wireless
services described above, it has not yet introduced any of these services. The
Company's ability to introduce these services on a commercial basis will depend
on a number of factors, including the availability of sufficient capital, the
success of the Company's development efforts, competitive factors (such as the
introduction of new technologies or the entry of competitors with significantly
greater resources than the Company), the level of consumer demand for such
services, the availability of appropriate transmission and reception equipment
on satisfactory terms, and the Company's ability to obtain the necessary
regulatory changes and approvals. The Company expects that the market for any
such additional services will be extremely competitive. See "-- Competition."
 
     There can be no assurance that sufficient capital will be available on
terms satisfactory to the Company, or at all, to fund the introduction of such
digital wireless services, that the Company's development efforts will be
successful, that the Company will be able to obtain the necessary regulatory
approvals and changes to commercially introduce such services, that there will
be sufficient customer demand for such services to justify the cost of their
introduction in any of the Company's markets, or that the Company will be
successful in competing against existing or new competitors in the market for
such digital wireless services.
 
     The Company will require significant additional capital to fully implement
its digital strategy. To meet such capital requirements, the Company is pursuing
opportunities to enter into strategic relationships or transactions with other
providers of telecommunications services. These relationships could provide the
Company with access to technologies, products, capital and infrastructure. Such
relationships or transactions could involve, among other things, joint ventures,
sales or exchanges of stock or assets, or loans to or investments in the Company
by strategic partners. As of the date of this Report, except for the BellSouth
Agreement (as defined herein), the Company has not reached any agreements or
understandings with respect to such strategic relationships or transactions and
there can be no assurance that any such agreements or understandings will be
reached.
 
     During 1997, the Company intends to continue to operate its Developed
Markets principally as an analog wireless cable business. However, because of
its current financial condition and its revised business strategy, the Company
does not plan to make the capital expenditures necessary to add enough new
subscribers to replace those subscribers that choose to stop receiving the
Company's service. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations." Moreover, at this time, the Company does
not generally intend to further develop any of its Undeveloped Markets using
analog technology. Thus, the
 
                                        3
<PAGE>   5
 
Company anticipates that its analog customer base will decrease somewhat during
1997. As the Company's analog subscriber base decreases, its revenues are
expected to decrease unless and until it is able to successfully introduce other
revenue-producing wireless services, such as those described above.
 
RECENT DEVELOPMENT
 
     On March 18, 1997, the Company entered into a definitive agreement (the
"BellSouth Agreement") with BellSouth Corporation and BellSouth Wireless
Corporation ("BellSouth Wireless") providing for the sale of all of the
Company's Florida and Louisville, Kentucky wireless cable assets (the
"Southeastern Assets") to BellSouth Wireless (the "BellSouth Transaction"). The
Southeastern Assets include operating wireless cable systems in Orlando,
Lakeland, Jacksonville, Daytona Beach, and Ft. Myers, Florida and Louisville,
Kentucky and wireless cable channel rights in Bradenton, Naples, Sebring and
Miami, Florida. As of December 31, 1996, the Southeastern Assets represented
approximately 2.6 million Estimated Households in Service Area and served over
35,000 subscribers.
 
     Pursuant to the BellSouth Agreement, the purchase price for all of the
Southeastern Assets will range from $67.9 million to $103.2 million, depending
upon the number of wireless cable channel rights that are ultimately transferred
to BellSouth Wireless. A first closing is expected to occur when all necessary
third party and governmental consents to the assignment of a minimum number of
channel positions in Orlando, Jacksonville, Daytona Beach, Ft. Myers, Miami,
Lakeland, Bradenton and Louisville have been obtained, which the Company expects
will occur prior to the end of the fourth quarter of 1997. The remainder of the
Southeastern Assets will be sold upon the satisfaction of certain closing
conditions that are specific to the markets involved, but in no event later than
two years after the date of the first closing.
 
     The BellSouth Agreement grants BellSouth Wireless a right of first refusal
in the event of a proposed sale by the Company of any wireless cable channel
rights that the Company owns or subsequently develops in Florida, Georgia,
Alabama, Mississippi, Louisiana, Kentucky, Tennessee, North Carolina or South
Carolina. The BellSouth Agreement also contains a covenant not-to-compete that
prohibits the Company from competing with BellSouth Wireless in the video
distribution business in the Florida and Louisville, Kentucky BTAs (as defined
herein) for a period of five years from the closing date.
 
     The BellSouth Agreement contains customary conditions to closing, including
the expiration of applicable waiting periods under the federal antitrust laws
and the satisfaction of all applicable regulatory requirements. There can be no
assurance that all of such conditions will be satisfied or that the BellSouth
Transaction will be consummated.
 
     The Company also has granted to BellSouth Wireless an option to purchase
for $9.0 million the Company's wireless cable channel rights in Yuba City,
California and the Company's Yuba City and Sacramento, California BTA
authorizations. The option can be exercised by BellSouth Wireless at any time
within 18 months after the date of the BellSouth Agreement.
 
SUBSCRIPTION TELEVISION INDUSTRY
 
     The subscription television industry began in the late 1940's and 1950's to
serve the needs of residents in predominantly rural areas with limited access to
local off-air VHF/UHF broadcasts. The industry expanded to metropolitan areas
due to, among other things, the fact that subscription television offered better
reception and more programming. Currently, subscription television systems offer
various types of programming, which generally include basic service, expanded
basic service, premium service, and, in some instances, pay-per-view service.
 
     A subscription television customer generally pays an initial connection
charge and a fixed monthly fee for basic service. The amount of the monthly
basic service fee varies from one area to another and is a function, in part, of
the number of channels and services included in the basic service package and
the cost of such services to the subscription television system operator. In
most instances, a separate monthly fee for each premium service and certain
other specific programming is charged to customers, with discounts generally
available to customers receiving multiple premium services. Monthly service fees
for basic, expanded basic, and premium
 
                                        4
<PAGE>   6
 
services constitute the major source of revenue for subscription television
systems. Customers normally are free to discontinue service at any time.
Converter rentals, remote control rentals, installation charges and reconnect
charges are also included in a subscription television system's revenues, but
generally are not a significant component of such revenues.
 
TRADITIONAL HARDWIRE CABLE TECHNOLOGY
 
     Most subscription television systems are franchise (hardwire) cable systems
that currently use a coaxial cable to transmit television signals. Traditional
hardwire cable operators receive, at a headend, signals for programming
services, such as CBS, NBC, ABC, FOX, HBO, Cinemax and CNN, which have been
transmitted to them by a broadcast or satellite transmission. A headend consists
of signal reception equipment and decryption, retransmission, encoding and
related equipment. The operator then delivers the signal from the headend to
customers via a distribution network consisting of coaxial cable, amplifiers and
other components ("Cable Plant"). As a direct result of the use of Cable Plant
to deliver signals throughout a service area, traditional hardwire cable systems
are susceptible to signal problems. Signals can only be transmitted via coaxial
cable a relatively short distance without amplification. Each time a television
signal passes through an amplifier, some measure of noise is added. A series of
amplifiers between the headend and the viewing customer leads to progressively
greater noise, and thus a grainier picture for some viewers. Also, an amplifier
must be properly balanced or the signal may be improperly amplified. Failure of
any one amplifier in the chain of Cable Plant will black out the system
transmission signal from that point on. Regular system maintenance is required
due to water ingress, temperature changes, and other equipment problems, all of
which may affect the quality of signals delivered to customers. Some franchise
cable operators have begun installing fiber optic networks which will
substantially reduce the transmission and reception problems currently
experienced by traditional franchise cable systems and expand channel capacity
of their systems. The installation of such networks will require a substantial
investment by franchise cable operators.
 
WIRELESS CABLE TECHNOLOGY
 
     The wireless cable industry was made commercially possible in 1983 when the
FCC reallocated a portion of the electromagnetic radio spectrum located between
2500 and 2700 MHz and permitted this spectrum to be used for commercial
purposes. At that time, the FCC also modified its rules on the usage of the
remaining portion of such spectrum. Nevertheless, regulatory and other obstacles
impeded the growth of the wireless cable industry through the remainder of the
1980s. For example, before the 1992 Cable Act (as defined herein) became
effective, a continued supply of programming from cable controlled programmers
was not assured. The factors contributing to the growth of wireless cable
systems since that time include: (i) regulatory reforms by the FCC to facilitate
competition for franchise cable operators; (ii) increased availability of
programming for wireless cable systems; (iii) consumer demand for an alternative
to traditional franchise cable; (iv) increasing accumulation by wireless cable
operators of a sufficient number of channels in each market to create a
competitive product; and (v) increased availability of capital to wireless cable
operators in the public and private markets.
 
     Like a traditional franchise cable system, a wireless cable system receives
programming at a headend. Unlike a traditional franchise cable system, however,
the programming is then retransmitted by a microwave transmitter from an antenna
located on a tower associated with the headend to a small microwave receiver
located at the customer's premises. At the customer's location, the signals are
converted to frequencies that can pass through conventional coaxial cable into a
descrambling converter located on top of a television set. Wireless cable
requires a clear line-of-sight because the microwave frequencies used will not
pass through dense foliage, hills, buildings, or other obstructions. Some of
these obstructions can be overcome with the use of signal repeaters, which
retransmit an otherwise blocked signal over a limited area. Since wireless cable
systems do not require extensive Cable Plant, wireless cable operators are
capable of providing customers with a high-quality picture with few transmission
disruptions at a significantly lower system capital cost per installed customer
than traditional hardwire cable systems.

REGULATION
 
     The subscription television industry is highly regulated. Wireless cable
companies are subject to both federal and local regulation, as described below.
 
  Federal Communications Commission
 
     The FCC has authorized access for wireless cable service to a series of
channel groups, consisting of certain channel groups specifically allocated for
wireless cable ("MDS"), and other channels originally authorized for educational
purposes ("ITFS"), although excess capacity can be leased from ITFS licensees by
wireless cable providers. Currently, up to 33 total channels are potentially
available for licensing, lease or purchase by wireless cable companies in each
market. Up to 13 channels in any given market typically can be owned by
commercial operators for full-time usage without programming restrictions. The
remaining 20 channels in a given market generally are allocated for ITFS use.
FCC rules generally prohibit the ownership or leasing of MDS and ITFS
authorizations by cable companies if the MDS facility is located within 35
miles, or the ITFS facility is located within 20 miles, of the cable company's
franchise or service areas. Pursuant to the 1996 Act, the cable-MDS rule does
not apply to a cable operator in a franchise area in which the operator is
subject to effective competition.
 
     Authorizations have been issued, or are currently pending, for the majority
of MDS wireless cable licenses in most major U.S. markets, and, as discussed
below, under the current regulatory structure, only holders of a BTA
authorization may apply for available MDS frequencies within the BTA. In a
number of markets, certain ITFS frequencies are still available. However, except
as noted below, eligibility for ownership of ITFS licenses is limited to
accredited educational institutions, governmental organizations engaged in the
formal education of enrolled students and non-profit organizations whose
purposes are educational and include providing educational and instructional
television material to such accredited institutions and governmental
organizations ("qualified ITFS educational entities"). Non-local applicants must
demonstrate that they have arranged with local educational entities to provide
them with programming and that they have established a local programming
committee.
 
     On July 10, 1996, the FCC adopted an Order in which it authorized the
interim use of certain digital compression technologies for the provision of
video, voice and data services over MDS and ITFS frequencies. Such technology
may be utilized by a wireless cable operator or an MDS or ITFS licensee, after
applying for, and being granted, such an authorization by the FCC. The Company
has filed, and will continue to file, applications for digital authorizations in
many of its markets. The FCC has begun granting digital authorizations. Upon
receiving a digital authorization, a licensee also may transmit one-way
downstream Internet service. The Company, along with other wireless cable
industry companies, petitioned the FCC in March 1997 to expand its digital
authorizations to permit the grant of applications for two-way transmission of
interactive services over MDS and ITFS frequencies. The petition proposes rule
changes necessary for the FCC to routinely grant wireless cable companies the
right to implement two-way wireless services without licensing delays. There can
be no assurance that the petition will be granted, or if granted, that the
Company will be able to develop commercially successful products using two-way
transmission.
 
     FCC rules require ITFS operators to transmit a minimum amount of
educational programming per channel per week. If the educational programming
minimums are met, remaining airtime can be leased to wireless cable operators
for profit and used to transmit non-educational programming. ITFS licensees are
now entitled to meet their minimum educational programming requirements for all
licensed channels using only one channel via "channel loading," if desired.
 
     Beginning in November 1995, the FCC auctioned all available MDS rights on
the basis of Basic Trading Areas ("BTAs"), with one such authorization available
per BTA. The winning bidder acquired the right to apply to operate one or more
MDS stations within the BTA, as long as its station proposals complied with the
FCC's interference requirements and other rules. With regard to commercial ITFS
channels, only the BTA license holder may apply for available authorizations
within the BTA. A BTA licensee has a five-year build-out period within which to
expand or initiate new service within its BTA. It may sell, trade or otherwise
alienate all or part of its rights in the BTA and may also partition its BTA
along geopolitical boundaries and
 
                                        6
<PAGE>   8
 
contract with eligible parties to allow them to apply for MDS authorizations
within the partitioned area, and conversely, acquire such rights from other BTA
licensees. The license term for each station authorized under these BTA
procedures is ten years, commencing on the date that the FCC announced that the
auction for the BTA had closed.
 
     The Company was the winning bidder in 59 BTAs and, as of December 31, 1996,
had been issued MDS authorizations in 55 of its BTAs. The Company has filed
applications for MDS licenses in the other four BTAs in which it was the winning
bidder. The FCC must approve these applications before the MDS authorizations
will be issued. Competing applications cannot be filed but the FCC will consider
petitions to deny the Company's applications. There can be no assurance that the
FCC will approve the Company's remaining applications. As long as the Company
continues to hold the BTA rights in any given market, other entities seeking new
licenses or certain modifications to existing licenses within such market must
seek approval from the Company, as the BTA owner. Similarly, to the extent the
Company wishes to obtain new licenses or certain modifications to its existing
licenses in markets in which it was not the BTA winner, it will be required to
negotiate with the BTA owner for approval of such licenses or modifications.
 
     Certain of the Company's MDS applications were filed prior to adoption of
the BTA rules. Once such MDS applications are processed by the FCC and the
Company resolves any deficiencies identified by the FCC, a conditional license
is expected to be issued, allowing construction of the station to commence.
Construction of such stations generally must be completed within one year after
the date of grant of the conditional license. ITFS authorization holders
generally have 18 months within which to construct the station. All ITFS
licenses have terms of ten years and most current non-BTA MDS licenses will
expire on May 1, 2001. The FCC's standards for renewal of MDS and ITFS licenses
are similar to those for other FCC licenses. Licenses also may be revoked for
cause in a manner similar to other FCC licenses. FCC rules prohibit the sale for
profit of an MDS authorization not obtained by auction or of a controlling
interest in the licensee of such a facility prior to construction of the station
or, in certain instances, prior to the completion of one year of operation. The
FCC, however, does permit the leasing of 100% of an MDS licensee's spectrum
capacity to a third party and the granting of options to purchase a controlling
interest in an authorization once the required time period has lapsed.
 
     The Company is also subject to various FCC regulatory limitations relating
to ownership and control. The Communications Act and FCC rules require the FCC's
approval before a license may be assigned or control of the holder of a license
may be transferred. Moreover, the Act provides that certain types of licenses,
including those for MDS stations, may not be held directly by corporations of
which non-U.S. citizens or entities ("Aliens") own of record or vote more than
20% of the capital stock. In situations in which such an FCC license is directly
or indirectly controlled by another corporation, Aliens may own of record or
vote no more than 25% of the controlling corporation's capital stock.
 
     In light of these restrictions, ATI amended its certificate of
incorporation in April 1995 to require that all of its officers and directors be
U.S. citizens and to empower the Board of Directors to redeem ATI's outstanding
capital stock to the extent necessary to protect the loss or secure the
reinstatement of any license or franchise from any governmental agency if a
situation arises whereby more than the permitted percentage of outstanding
capital stock of ATI is owned or voted by Aliens. Moreover, the amendments
adopted in April 1995 provide that, in such circumstances, no transfers of
shares may be made to Aliens and shares causing ATI to exceed the statutory
limit may neither be voted, receive dividends, nor be entitled to any other
rights, until transferred to U.S. citizens.
 
  Telecommunications Act of 1996
 
     On February 8, 1996, the Telecommunications Act of 1996 (the "1996 Act")
became law. Among other things, the 1996 Act eliminates the cable/telephone
cross-ownership restriction, allowing a telephone company the option of
providing video programming within its telephone service area over a cable
system or a video platform. Conversely, cable companies are now permitted to
provide telephone service. The 1996 Act also limits, and in some cases
eliminates, FCC regulation of cable rates established by the Cable Television
Consumer Protection and Competition Act of 1992 (the "1992 Cable Act"),
depending upon the size of the
 
                                        7
<PAGE>   9
 
cable system and whether the system is subject to effective competition and the
nature of the rate. Specifically, regulation of upper tier rates is scheduled to
end March 31, 1999. Moreover, small cable operators and systems subject to
effective competition are now exempt from rate regulation as a result of the
1996 Act. The 1996 Act also vests the FCC with exclusive jurisdiction over the
provision of DBS (as defined herein) service and preempts the authority of local
authorities to impose certain taxes on such services.
 
     While current FCC regulations are intended to promote the development of a
competitive subscription cable television industry, there can be no assurance
that these regulations will have a favorable impact on the Company. Changes in
FCC policies or procedures could have a negative effect on the wireless cable
industry as a whole and/or the Company in particular. In addition, the FCC's
regulation of other spectrum could permit the operation of other wireless
services to interfere with MDS and ITFS frequencies.
 
  Pending Legislation
 
     Legislation has been introduced in several states that would authorize
state and local authorities to impose taxes on providers of subscription
television programming, including wireless cable operators, based upon their
gross receipts. Because the nature of any such legislation, if enacted, is
unknown, the Company cannot predict what impact such legislation would have upon
its operations.
 
  Other Forms of Regulation
 
     Federal law requires that all "cable companies," as defined by Section 602
of the Communications Act, obtain local or state franchises prior to
constructing a subscription television distribution system. Because wireless
cable systems deliver programming to subscribers by means of microwave
facilities rather than through coaxial cable and are not specifically defined as
"cable systems" in Section 602 of the Communications Act, the 1992 Cable Act, or
in earlier statutes or FCC regulations, they have not been considered cable
companies under FCC rules in this context. Accordingly, wireless cable companies
generally are not required to obtain franchises and are generally not subject to
state regulation by public utility or cable commissions.
 
     The Company's Lakeland system (which was acquired in September 1994)
consists of a hybrid of wireless cable and franchise cable, the latter being
utilized to serve areas that are not reached by the system's microwave signals
or to distribute programming to limited areas, such as apartment buildings,
housing subdivisions and mobile home parks. This system is deemed a "cable
company" under the Communications Act and the FCC's rules promulgated
thereunder. As such, this system is subject to regulation under some or all of
the federal, state and local rules that govern traditional franchise cable
operators.
 
     Similarly, the Company's subscription television assets in Cincinnati, Ohio
include both wireless cable and SMATV facilities, the latter of which have been
deemed by the FCC to constitute cable systems. By letter dated October 17, 1996,
the FCC provided a temporary waiver of the cable/MDS cross-ownership rules to
allow the common ownership and operation of these facilities, which will expire
on November 5, 1997. By that date, the Company will be required to take all
actions necessary to comply with these rules, including possible divestiture.
 
     Wireless cable operators also are subject to regulation by the Federal
Aviation Administration and the FCC with respect to construction of transmission
towers and certain local zoning regulations affecting construction of such
towers and other facilities. Additional restrictions may also be imposed by
local authorities, neighborhood associations and other similar organizations
limiting the use of certain types of reception equipment used by the Company and
its subscribers.
 
COMPETITION
 
     The subscription television industry is highly competitive. Currently, the
Company's existing and potential competitors consist of a broad range of
companies engaged in the communications and entertainment businesses, including
cable operators, digital satellite program providers, television networks and
home video products companies. To date, the Company has sought to differentiate
itself from its competitors through lower priced, streamlined pricing plans,
service guarantees, high-quality customer service and system
 
                                        8
<PAGE>   10
 
performance, and local community involvement and support. In the future, the
Company expects to face intense competition from numerous other companies
offering video, audio and data products and services. Many of the Company's
existing or potential competitors have substantially greater name recognition
and financial, technical and human resources than the Company and may be better
equipped to develop and operate systems providing subscription television
service, high-speed Internet access and telephony services. The Company's
principal existing and potential competitors are described below:
 
  Franchise Cable Systems
 
     Currently, the Company's principal competitors are franchise cable
companies that own local franchises to operate their systems in the Company's
markets. Cable television service is currently available to the vast majority of
U.S. television households. In most instances, the franchise cable operators
with which the Company competes serve more subscribers on both a local and
national level. Franchise cable companies typically offer a larger selection of
programming than the Company. The Company seeks to compete with franchise cable
companies by offering the most widely demanded programming choices at lower
prices, combined with high-quality customer service.
 
     The Company believes that a number of franchise cable operators will be
required to significantly upgrade their coaxial systems to provide digital
programming, which will involve a substantial investment of capital. Many cable
television providers are already in the process of upgrading their systems and
other cable operators have announced their intentions to make significant
upgrades. A number of proposed technological improvements, when fully completed,
will permit cable companies to increase channel capacity, thereby increasing
programming alternatives, and to deliver a better quality signal without
significant upgrades to their systems.
 
     Many of the largest cable systems in the United States have announced plans
to offer data and telephony service through upgraded networks, and have entered
into agreements with major telephony providers to further these efforts. In some
cases, trials of data and telephony services are underway. In the event that
these trials are successful, the cable operators who are capable of offering
both data and telephony services will have a competitive advantage over wireless
companies if consumers choose to receive both their cable and telephone service
from the same operator.
 
  Direct Broadcast Satellite ("DBS")
 
     DBS involves the transmission of an encoded signal direct from a satellite
to the customer's home. Because the signal is at a higher power level and
frequency than most satellite-transmitted signals, its reception can be
accomplished with a relatively small (18-inch) dish mounted on a rooftop or in
the customer's yard.
 
     The cost of constructing and launching the satellites used to distribute
DBS programming is substantial. When first introduced, DBS reception equipment
for a single television set cost approximately $650 per customer, plus
installation fees, service charges and off-air antenna installation, where
applicable. Furthermore, each additional, independent outlet requires a separate
descrambling device at additional cost to the subscriber. These prices have
decreased as additional competitors have entered the DBS market. Recent
promotions have offered DBS reception equipment for less than $150 (exclusive of
installation and other charges) when the consumer agrees to prepay a one-year
subscription fee. The Company's principal DBS competitors are described below.
 
     DirecTV, Inc. ("DirecTV"), which is substantially owned by GM-Hughes
Electronics, successfully launched its first satellite in December 1993, its
second satellite in August 1994, and a third satellite as an in-orbit spare in
June 1995. The third satellite may also be operated by DirecTV to provide
additional capacity. Each of DirecTV's satellites are high power satellites. As
of December 31, 1996, according to trade publications, DirecTV served
approximately 2.3 million subscribers. Recently, AT&T Corporation ("AT&T") and
DirecTV entered into an exclusive agreement for AT&T to market and distribute
DirecTV's DBS service and related equipment to AT&T's large customer base. As
part of the agreement, AT&T made an initial investment of approximately $137.5
million to acquire 2.5% of the equity of DirecTV, with an option to
 
                                        9
<PAGE>   11
 
increase its investment to up to 30% over five years. This agreement provides a
significant base of potential customers for DirecTV's DBS systems and allows
AT&T and DirecTV to offer customers a package of digital entertainment and
communications services. AT&T and DirecTV have also announced plans to jointly
develop new multimedia services for DirecTV under the agreement.
 
     United States Satellite Broadcasting Corporation ("USSB") owns and operates
DBS spectrum on DirecTV's first satellite and offers a programming service
separate from DirecTV's service. As of December 31, 1996, this programming
service had over 25 channels of premium video programming not available from
DirecTV. USSB's selection of programming services (and its use of transponders
on the same satellite used by DirecTV, which enables subscribers to receive both
DirecTV and USSB signals with a signal satellite receiver) allows it to be
marketed as a complementary service to DirecTV, partially offsetting the
competitive handicap caused by its relatively limited channel capacity.
According to trade publications, as of December 31, 1996, approximately one-half
of DirecTV's 2.3 million subscribers received USSB programming.
 
     PrimeStar Partners ("PrimeStar") currently offers medium power Ku-band
programming service to customers using dishes approximately three feet in
diameter. PrimeStar is owned by a group of franchise cable operators and
provides service nationwide. According to trade publications, PrimeStar had
approximately 1.6 million subscribers as of December 31, 1996.
 
     EchoStar Communications Corporation ("EchoStar") launched a high power
satellite in December 1995, commenced national broadcasting of programming
channels in March 1996 and, as of December 31, 1996, broadcasted approximately
150 channels of programming. EchoStar has announced plans to increase its
program offering through the launch of two additional satellites (one in each of
1997 and 1998). As of December 31, 1996, EchoStar had approximately 350,000
subscribers, according to trade publications.
 
     During 1996, MCI Communications Corporation ("MCI") acquired high power DBS
spectrum with the capacity to offer over 200 channels of digital video
programming for $682.5 million in an FCC auction. Thereafter, MCI entered into a
joint venture with The News Corporation ("News Corp") to build and launch a high
power digital satellite system. On February 24, 1997, EchoStar and News Corp
announced that News Corp had agreed to acquire a 50% ownership interest in
EchoStar in exchange for aggregate consideration of approximately $1.0 billion
(such consideration consisting of cash and certain DBS assets). The EchoStar/
News Corp alliance, which will do business using the "Sky" brand name, announced
that it plans to provide approximately 500 channels of digital programming,
including local broadcast signals, by the end of 1998 to a majority of the
continental United States. As a result of its alliance with News Corp, EchoStar
will have substantially greater financial and other resources than the Company
and can be expected to increase the competition that the Company encounters in
the overall market for subscription television customers.
 
  C-band Satellite Program Distributors
 
     The Company also competes with C-band satellite program distributors (also
referred to as "backyard dish" or television receive only ("TVRO") systems).
C-band systems have been popular (mostly in rural and semi-rural areas) since
the late 1970s, and currently serve approximately 2.1 million subscribers in the
aggregate, according to trade publications. The primary advantages of wireless
cable systems over TVRO systems are lower equipment costs and broader
availability of local programming. TVRO systems, on the other hand, enjoy the
advantage of access to a wider variety of satellite programming and serve areas
not served by franchise or wireless cable systems. A conventional TVRO antenna
system costs in excess of $1,000 per subscriber, and subscribers are charged
monthly fees for access to certain programming. TVRO systems typically cannot
receive local off-air broadcast channels.
 
  Telephone Companies
 
     Certain regional and long distance telephone companies could become
significant competitors of the Company in the future, as they have expressed an
interest in becoming subscription television providers. The 1996 Act removes
barriers to entry that previously inhibited telephone companies from competing,
or made it more difficult for telephone companies to compete, in the provision
of video programming and information services. Certain telephone companies have
received authorization to test market video and other services in
 
                                       10
<PAGE>   12
 
certain geographic areas using fiber optic cable and digital compression over
existing telephone lines. Estimates for the timing of wide-scale deployment of
such multichannel video service vary, as several telephone companies have pushed
back originally announced deployment schedules.
 
     As more telephone companies begin to provide subscription television
programming and other information and communications services to their
customers, significant additional competition for subscribers is expected to
develop. Among other things, telephone companies have an existing relationship
with substantially every household in their service area, substantial financial
resources and an existing infrastructure, and may be able to subsidize the
delivery of programming through their position as the sole source of telephone
service to the home.
 
  VHF/UHF Broadcasters
 
     Most areas of the United States are covered by traditional territorial
over-the-air VHF/UHF broadcasters. Consumers can receive from three to ten
channels of over-the-air programming in most markets. These stations provide
local, network and syndicated programming free of charge, but each major market
is generally limited in the number of programming channels. Congress is expected
to consider the release of additional digital spectrum for use by VHF/UHF
broadcasters in the delivery of high definition television services later in
1997.
 
  Private Cable
 
     Private cable is a multi-channel subscription television service where the
programming is received by a satellite receiver and then transmitted via coaxial
cable throughout private property, often multiple dwelling units ("MDUs"),
without crossing public rights of way. Private cable operates under an agreement
with a private landowner to service a specific MDU, commercial establishment or
hotel. The FCC recently amended its rules to allow the provision of
point-to-point delivery of video programming by private cable operators and
other video delivery systems in the 18 GHz bandwidth. Private cable operators
compete with the Company for exclusive rights of entry into MDUs.
 
  Local Multi-Point Distribution Service ("LMDS")
 
     On March 13, 1997, the FCC released service and competitive bidding rules
for LMDS, which is located at 27.5 to 28.35 GHZ, 29.1 to 29.25 GHZ and 31.0 to
31.3 GHZ in the frequency band. There will be one 1150 MHz LMDS license and one
150 MHz LMDS license awarded for each BTA, for a total of 986 authorizations.
There will be no restrictions on the number of licenses an entity may hold, but
incumbent LECs and cable companies will not be able to obtain the 1150 MHz
licenses in-region for three years. A simultaneous multiple round auction will
be scheduled for later this year. Certain issues regarding geographic
partitioning and spectrum disaggregation are the subject of a pending
rulemaking. The rules for use of the spectrum are relatively broad, but it is
expected that the spectrum will be used for multichannel video programming,
telephony, video communications and data services, including two-way video
communications.
 
  Wireless Communications Service ("WCS")
 
     On February 19, 1997, the FCC announced service and auction rules for WCS,
which is located at about 2.3 GHz in the frequency band. There will be two 10
MHz WCS licenses for each of 52 major economic areas and two 5 MHz WCS licenses
for each of 12 regional economic area groupings. A simultaneous, multiple-round
electronic auction for the WCS licenses is expected to begin in April 1997. The
rules for use of the spectrum are relatively broad. Since the licenses involve
much less total spectrum than is available to other providers of subscription
television service, such as the Company, in a typical market, it is unlikely
that WCS license winners will be able to effectively compete with such
subscription television providers. However, WCS license winners could increase
competition in the data and wireless telephony businesses in the future. The
Company has not determined the degree of participation, if any, it will have in
the WCS auction.

MARKETS
 
     The Company operates under a decentralized management structure in order to
maximize the Company's local presence in each market. Most of the Company's
operational systems or system clusters are managed by a general or operations
manager who reports directly to a regional manager. General and operations
managers are responsible for the day-to-day operations of their respective
systems. Each operating system is staffed with customer service and sales
representatives and service technicians. Most non-executive employees of the
Company have incentive compensation programs that are tied to service quality
levels and sales goals. Pricing and programming decisions are made at the local
level, subject to review by the Company's executive management. Each of the
Company's analog wireless cable systems typically offers 15 to 25 basic cable
channels, one to three premium channels, and one or two pay-per-view channels.
Pay-per-view programming is offered only on an event-by-event basis in certain
of the Company's markets.

     Information regarding the Company's Markets as of December 31, 1996 is
presented in the following table. "Estimated Households in Service Area"
represents the approximate number of households within a 35 mile radius of the
Company's tower sites, subject to certain downward adjustments for overlapping
service areas. This information is based upon household estimates provided by
Strategic Mapping, Inc. using data obtained from the Donnelley Marketing Inc.
Residential Database. Some of these households will be "shadowed" and therefore
unable to receive the Company's service due to Line-of-Sight Constraints. The
percentage of Estimated Households in Service Area that the Company estimates
may be shadowed due to Line-of-Sight Constraints generally ranges from 10% to
50% depending upon the market.

- ---------------
 
(1) New station applications, petitions for reconsideration, and petitions for
    reinstatement are subject to approval by the FCC. The entities with which
    the Company has entered into leasing agreements have filed a series of
    applications for wireless cable channels. In many cases, the Company's
    applicant is the sole applicant. Due to the qualifications of the Company's
    applicants relative to competing filings, the Company expects that most of
    these applications will be approved by the FCC. However, there can be no
    assurance that these FCC applications will be approved.
 
(2) Represents total expected wireless channels (including channels not yet in
    service) plus local off-air broadcast channels which are generally available
    in the Company's broadcast signal area and which the Company does not expect
    to rebroadcast over its wireless cable channels.
 
(3) The Company is the BTA holder in this market. In certain cases, two or more
    of the Company's existing or target markets may be contained within a single
    BTA.
 
     In addition to the channel interests detailed above, the Company holds
channel rights in a number of other U.S. markets. The Company may seek
additional channel rights in these markets or sell or exchange the channel
rights it already holds.
 
     Pursuant to an Investment Agreement dated January 19, 1991, between CFW
Communications Company, a diversified publicly-traded telecommunications company
based in Waynesboro, Virginia ("CFW") and ATI (which agreement provided for the
purchase by CFW of 1,209,678 shares of ATI's Series A Convertible Preferred
Stock), the Company is entitled to receive payments equal to 10% of the earnings
(as defined in the agreement) of each wireless cable system developed by CFW in
the Commonwealth of Virginia for a 15-year period after each respective system
has achieved accumulated pre-tax income. In return, the Company is required to
provide certain advisory services to CFW in connection with the development of
such systems. CFW currently operates wireless cable systems in Richmond,
Charlottesville and other cities within the Shenandoah Valley, and maintains
certain wireless cable channel rights in Lynchburg and Winchester, Virginia.
 
ACQUISITIONS AND DIVESTITURES
 
     Since May 1993, the Company has acquired 22 operational wireless cable
systems and wireless cable channel rights in 18 additional markets, and has sold
two operational wireless cable systems and wireless cable channel rights in two
additional markets. On March 18, 1997, the Company entered into the BellSouth
Agreement, which provides for the sale of all of the Company's Southeastern
Assets to BellSouth Wireless. The Southeastern Assets include operating wireless
cable systems in Orlando, Lakeland, Jacksonville, Daytona Beach and Ft. Myers,
Florida and Louisville, Kentucky and wireless cable channel rights in Bradenton,
Naples, Sebring and Miami, Florida. The purchase price for all of the
Southeastern Assets will range from $67.9 million to $103.2 million, depending
upon the number of wireless cable channel rights that are ultimately transferred
to BellSouth Wireless. See "-- Recent Development". The BellSouth Agreement
contains customary conditions to closing, including the expiration of applicable
waiting periods under the federal antitrust laws and the satisfaction of all
applicable regulatory requirements. There can be no assurance that all of such
conditions will be satisfied or that the BellSouth Transaction will be
consummated. The Company may in the future pursue other opportunities to sell or
exchange certain of its wireless cable television assets. There can be no
assurance that the Company will be successful in completing any such
transactions.
 
PROGRAMMING
 
     The Company's analog wireless cable systems seek to offer popular
programming at affordable prices. The Company selects its basic programming
channels to appeal to a specific customer base and generally does not offer
programming which appeals to small, specialized market segments. The Company's
typical analog channel offering includes between 15 and 25 basic cable channels,
one to three premium channels (typically HBO, Showtime or the Disney Channel)
and one or two pay-per-view channels. Pay-per-view service is offered in certain
markets only on an event-by-event basis. Specific programming packages vary
according to
 
                                       14
<PAGE>   16
 
particular market demand. Local off-air channels are received by the subscriber
along with the Company's wireless channels, thereby adding, on average, four to
eight channels to the number of basic channels offered and resulting in
aggregate offerings currently ranging from 14 to 44 channels. Programming
expenses typically equal approximately one-third of the Company's revenue and
have been increasing relative to revenues. The Company could be adversely
affected if it cannot increase subscriber rates, because of market pressures or
otherwise, to offset increases in programming and other expenses.
 
SERVICE
 
     The Company's subscription television business emphasizes a strong
commitment to high-quality customer service. This commitment is evidenced, in a
number of the Company's Developed Markets, by seven-day-a-week,
fixed-appointment-time installations; same-day response to service call
requests; short telephone hold times; and extended office, telephone and
technical service hours.
 
SALES AND MARKETING
 
     In marketing its subscription television service, the Company continues to
target specific consumer segments which have demonstrated a propensity toward
value-added choices and offers specific marketing programs based on local
demand, general market characteristics, and customer surveys.
 
EQUIPMENT AND FACILITIES
 
     The Company's analog wireless cable systems utilize fully addressable
subscriber equipment. In-home wireless subscriber equipment components used in
the Company's systems are generally similar to those used in franchise cable
systems. Subscriber equipment includes a microwave receiver, downconverter,
set-top converter and remote control unit. The Company is not dependent upon any
one supplier for its equipment needs.
 
LICENSES AND CHANNEL LEASES
 
     The Company generally does not hold FCC licenses for channels that it uses
to broadcast programming; instead, it has acquired the right to broadcast under
long-term leases with third party licensees. The average term of the Company's
channel leases, including renewals at the Company's option, is more than ten
years. Although the Company anticipates that it will continue to have access to
a sufficient number of channels to operate a successful wireless cable system,
if a significant number of the Company's channel leases are not renewed, a
significant number of its pending FCC applications are not granted, or the FCC
terminates, forfeits, revokes or fails to renew the authorizations held by the
Company's channel lessors, ATI may be unable to provide a viable programming
package to subscribers in some or all of its markets.
 
     Prior to November 1993, the Company was a direct FCC licensee with respect
to approximately ten wireless cable authorizations used by its systems to
broadcast programming and had applications pending with the FCC regarding 39
other authorizations. In November and December 1993, the Company assigned its
FCC licenses, and filed amendments to assign these pending FCC applications, to
Wireless Properties, Inc., Wireless Properties of Virginia, Inc., Wireless
Properties -- East, Inc. or Wireless Properties -- West, Inc. (collectively, the
"Wireless Companies"). The Wireless Companies are owned and controlled by Donald
R. DePriest, Chairman of the Board of Directors and a Director of ATI. In
return, the Wireless Companies agreed to grant to the Company the exclusive
right to use such FCC licenses for an initial term of five years and, at the
Company's option, for an unlimited number of successive one-year terms
thereafter, pursuant to certain channel lease agreements. The Wireless Companies
assigned the majority of such licenses back to the Company during 1996. The
annual lease payments required to be paid by the Company pursuant to its channel
lease agreements with the Wireless Companies were nominal.
 
                                       15
<PAGE>   17
 
EMPLOYEES
 
     As of December 31, 1996, the Company had approximately 640 employees. The
Company considers relations with its employees to be satisfactory. The Company
also uses independent contractors to perform some installations and door-to-door
sales.
 
ITEM 2. PROPERTIES
 
     The principal physical assets of a wireless cable system consist of
satellite signal reception equipment, radio transmitters and transmission
antennas, as well as office space and transmission tower space. The Company's
principal office is located in approximately 18,000 square feet of leased office
space in Colorado Springs, Colorado. The Company occupies this space under a
lease agreement that expires in 2000. The Company believes that such office
space in Colorado Springs is adequate for the near future. The Company currently
leases additional office and warehouse space in each of its Developed Markets
and certain of its Undeveloped Markets pursuant to lease agreements that expire
at various times over the next three to five years.
 
     The Company also leases tower transmission space in all of its Developed
Markets (except for three markets where it owns transmission towers) and certain
of its Undeveloped Markets, pursuant to long-term lease arrangements. The
Company's tower lease agreements provide for locating transmitter, antenna and
other equipment at existing towers to broadcast wireless cable signals. The
agreements generally cover a period of five to seven years and are subject to
renewal upon expiration. To date, the Company has been able to obtain suitable
tower space on satisfactory terms in each of its Developed Markets. In the event
that any one or more of these tower space leases is terminated or not renewed
upon expiration, the Company will be required to obtain alternative tower space
in order to broadcast its programming.
 
ITEM 3. LEGAL PROCEEDINGS
 
     On or about February 17, 1994, Fresno Telsat, Inc. ("FTI"), the 35% general
partner of Fresno MMDS Associates ("the Fresno Partnership") which operates the
Company's Fresno, Merced and Visalia wireless cable systems, filed a Complaint
in the Superior Court of the State of California for the County of Monterey
against Robert D. Hostetler, Terry J. Holmes, the Company, and certain other
named and unnamed defendants. From 1989 through June 10, 1993, Mr. Hostetler was
a member of the Board of Directors and President of FTI. Mr. Hostetler and his
wife currently own 28% of the outstanding capital stock of FTI. Mr. Hostetler
has been employed by the Company since December 10, 1993 and became a Director
of the Company on March 22, 1994. In January 1996, Mr. Hostetler was appointed
President and Chief Executive Officer of the Company. From 1991 until June 1995,
Mr. Holmes was General Manager of the Fresno Partnership. He is currently
Managing Director of the Fresno Partnership. Mr. Holmes has been employed by the
Company since June 1995, and became Vice President -- Operations of the Company
in January 1996. The Complaint alleges that, while he was a director and
employee of FTI, Mr. Hostetler engaged in wrongful conduct, including
misappropriation of corporate opportunity, fraud and unfair competition by
exploiting business opportunities that were the property of FTI. The Complaint
also alleges that Mr. Holmes engaged in a misappropriation of corporate
opportunities belonging to FTI. The Complaint further alleges that all
defendants, including the Company, participated in a conspiracy to
misappropriate corporate opportunities belonging to FTI and that the Company and
the unnamed defendants engaged in wrongful interference with fiduciary
relationship by intentionally causing Mr. Hostetler to breach his fiduciary duty
to FTI and causing Mr. Hostetler to wrongfully transfer FTI's corporate
opportunities to the Company.
 
     On August 28, 1996, ATI filed a Cross-Complaint (the "Cross-Complaint")
against FTI and certain of its officers and directors (the "Cross-Defendants").
The Cross-Complaint alleges that the Cross-Defendants have engaged in a
violation of Section 26-1-8-401 of the Indiana Code, conversion, conspiracy, and
breach of trust by failing to acknowledge and record ATI's ownership of
approximately 7% of FTI's capital stock purchased by ATI from a former
shareholder of FTI, and continuing to represent that FTI qualifies for
Subchapter S status under the Internal Revenue Code. The Cross-Complaint seeks
specific performance of the transfer of shares to ATI, compensatory damages,
punitive damages, an injunction against any further
 
                                       16
<PAGE>   18
 
actions by the Cross-Defendants in breach of trust or with the effect of
dissipating and diverting the property and assets of FTI, and the appointment of
a receiver to handle the affairs of FTI during the pendency of the FTI
proceeding.
 
     On or about February 24, 1997, the Company and Mr. Holmes each filed a
motion for summary judgment seeking dismissal of the claims in the Complaint
relating to an alleged conspiracy to misappropriate corporate opportunities of
FTI. The motion to dismiss is scheduled to be heard on April 25, 1997. On or
about March 5, 1997, FTI filed a motion for leave to amend the Complaint to add
allegations that ATI aided and abetted Mr. Hostetler's misappropriation of
corporate opportunity and that all defendants wrongfully interfered with FTI's
prospective business opportunities.
 
     The Complaint seeks compensatory damages (in an unspecified amount but
estimated by the plaintiff to be no less than $5 million) and exemplary damages
against all defendants, costs, an accounting, injunctive relief prohibiting Mr.
Hostetler from continuing to engage in unfair competition against FTI and
prohibiting all defendants from engaging in misappropriation of corporate
opportunities belonging to FTI, and the imposition of a constructive trust upon
the corporate opportunities of FTI utilized in the Company's initial public
offering. While discovery has commenced in this proceeding, no trial date has
been scheduled. Although the ultimate outcome of the litigation cannot be
predicted at this time, management believes, based upon its review of the
Complaint and after consultation with counsel, that resolution of this matter
will not have a material adverse impact on the Company's financial position or
future results of operations.
 
     On January 12, 1996, Videotron (Bay Area) Inc. filed a complaint against
ATI in the Circuit Court of the Thirteenth Judicial Circuit in and for
Hillsborough County, Florida. The Complaint alleges that ATI has caused certain
entities from which ATI leases channels and airtime for its Bradenton and
Lakeland, Florida wireless cable markets (the "ATI Lessors") to actively oppose
Videotron's FCC applications to increase broadcast power in Videotron's Tampa,
Florida wireless cable system (the "Tampa market") in violation of a
Non-Interference Agreement between Videotron and ATI (the "Non-Interference
Agreement"). The Complaint seeks injunctive relief directing ATI to perform all
acts, services and undertakings required under the Non-Interference Agreement,
including but not limited to using reasonable best efforts to cause the ATI
Lessors not to object to Videotron's attempt to increase broadcast power in the
Tampa market and to enter into certain non-interference agreements with respect
thereto. In the alternative, the Complaint seeks damages for breach of the
Non-Interference Agreement (in an unspecified amount but exceeding $15,000).
Recently, in responding to written interrogatories, Videotron estimated its
damages to be approximately $113.5 million. Although the ultimate outcome of
this litigation cannot be predicted at this time, management of ATI believes,
based upon its review of the Complaint and after consultation with counsel, that
resolution of this matter will not have a material adverse impact on the
Company's financial position or future results of operations.
 
     In addition, the Company is occasionally a party to legal actions arising
in the ordinary course of its business, the ultimate resolution of which cannot
be ascertained at this time. However, in the opinion of management, resolution
of these matters will not have a material adverse effect on the Company.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

solicitation of proxies or otherwise, during the fourth quarter of 1996.

     As of March 11, 1997, there were approximately 408 record holders of the
Company's Class A Common Stock, not including stockholders who beneficially own
Class A Common Stock held in nominee or street name. As of March 11, 1997, there
were approximately 5,000 beneficial owners of the Company's Class A Common Stock
held in nominee or street name.
 
     The Company has never declared or paid any cash dividends on its Class A
Common Stock and does not expect to declare dividends in the foreseeable future.
Payment of any future dividends will depend upon the earnings and capital
requirements of the Company, the Company's debt facilities, and other factors
the Board of Directors considers appropriate. The Company currently intends to
retain its earnings, if any, to support future growth and expansion. The
Company's ability to declare dividends is affected by covenants in certain debt
facilities that prohibit the Company from declaring dividends and the Company's
subsidiaries from transferring funds in the form of cash dividends, loans or
advances to ATI. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
     All statements contained herein that are not historical facts, including
but not limited to, statements regarding the Company's plans for future
development and operation of its business, are based on current expectations.
These statements are forward looking in nature and involve a number of risks and
uncertainties. Actual results may differ materially. Among the factors that
could cause actual results to differ materially are the following: a lack of
sufficient capital to finance the Company's business plan on terms satisfactory
to the Company; pricing pressures which could affect demand for the Company's
wireless communications services; changes in labor, equipment and capital costs;
the unavailability of digital compression technology and equipment at reasonable
prices; the Company's inability to incorporate digital compression technology
into certain of its subscription television systems in a cost efficient manner;
the Company's inability to develop and implement new services such as high-speed
Internet access and telephony; the Company's inability to obtain the necessary
authorizations from the FCC for such new services; competitive factors, such as
the introduction of new technologies and competitors into the wireless
communications business; a failure by the Company to attract strategic partners;
general business and economic conditions; and the other risk factors described
from time to time in the Company's reports filed with the SEC. The Company
wishes to caution readers not to place undue reliance on any such forward
looking statements, which statements are made pursuant to the Private Securities
Litigation Reform Act of 1995, and as such, speak only as of the date made.
 
INTRODUCTION
 
     During 1996, the Company's business strategy evolved to adapt to the
significant regulatory and technological changes that have occurred recently in
the telecommunications industry and to the Company's capital constraints. See
"Business -- Regulation" and "Business -- Competition." Management now believes
that the most promising use of the Company's wireless assets may be to provide a
variety of digital wireless services, instead of the traditional analog-based
technology utilized by the Company to date. Such digital wireless services could
include digital video (i.e., subscription television), high-speed Internet
access and telephony services. A successful deployment of such services might
include the full bundle of broad band (i.e., video and high-speed Internet) and
narrow band (i.e., telephony) services. While the Company has begun planning and
testing of these wireless services, it has not yet introduced any of these
services. As more fully described above under "Business -- Certain Requirements
and Uncertainties," the Company's ability to introduce these services will
depend on a number of factors, including the availability of sufficient capital,
competitive factors (such as the introduction of new technologies or the entry
of competitors with significantly greater resources than the Company), the level
of consumer demand for such services, and the Company's ability to obtain the
necessary regulatory changes and approvals.
 
     During 1997, the Company intends to continue to operate its Developed
Markets principally as an analog wireless cable business. However, because of
its current financial condition and its revised business strategy, the Company
does not plan to make the capital expenditures necessary to add enough new
subscribers to replace those subscribers that choose to stop receiving the
Company's service. Moreover, at this time, the Company does not generally intend
to further develop any of its Undeveloped Markets using analog technology. Thus,
the Company anticipates that its analog customer base will decrease somewhat
during 1997. As the Company's analog subscriber base decreases, its revenues are
expected to decrease unless and until it is able to successfully introduce other
revenue-producing wireless services, such as digital video, high-speed Internet
access and telephony.
 
     Since early 1996, the Company has taken certain actions aimed at reducing
its costs and conserving its capital, including reductions in the size of the
Company's workforce and decreases in capital expenditures and discretionary
expenses. As a result, the Company currently expects that its existing cash and
investment balances, proceeds from the Credit Facility (as defined herein), and
cash generated from operations will be sufficient to finance its operations
during 1997. Thereafter, additional financing will be required. If the Company's
capital resources are not sufficient to finance its operations, either in 1997
or thereafter, the Company will be required to curtail its operations and
development plans, which curtailment could involve, among other things, a
complete cessation of new customer additions. In March 1997, the Company entered
into an agreement to sell certain assets to BellSouth Wireless with anticipated
proceeds to the Company
 
                                       21
<PAGE>   23
 
ranging from $67.9 million to $103.2 million, depending on the number of
wireless cable channel rights that are ultimately transferred to BellSouth
Wireless. See "Business -- Recent Development." Any such proceeds will provide
further resources to help finance the Company's operations and development
plans. In addition, the Company is pursuing strategic relationships or
transactions with other providers of telecommunications services. One of the
Company's primary objectives in pursuing such relationships and transactions is
to facilitate access to additional capital. See "-- Liquidity and Capital
Resources -- Sources and Uses of Funds -- Strategic Relationship Objectives."
 
     The Company's Developed Markets generate negative operating cash flow until
the subscriber base becomes sufficiently large for incremental revenues, net of
incremental costs, to offset fixed costs, other than depreciation and other
non-cash expenses. Certain costs, such as programming costs, generally increase
in proportion to the number of subscribers, while other costs, such as tower
rental and related maintenance costs, remain constant or increase at
proportionately lower levels. Accordingly, systems with larger subscriber bases
generally produce higher operating margins, and systems with small subscriber
bases usually produce negative operating margins. For the year ended December
31, 1996, 24 of the Company's 38 Developed Markets generated positive operating
cash flow.
 
     Operating cash flow is a commonly used measure of performance in the
wireless cable industry. However, operating cash flow does not purport to
represent cash used by operating activities and should not be considered in
isolation or as a substitute for measures of performance prepared in accordance
with generally accepted accounting principles.
 
     The Company leases many of the channels used to transmit its programming
from FCC license holders. Typically, these leases provide for payments based
upon the number of subscribers, subject in many cases to certain minimums, as
more fully discussed in the Notes to the Company's Consolidated Financial
Statements included herein. Total channel lease payments approximated 4.1% of
total revenues during the year ended December 31, 1996. Total programming
expenses approximated 31.2% of total revenues during the same period. Such
expenses vary from system to system depending upon the number of channels
offered and pay channel penetration. Marketing costs are expensed in the period
incurred. As a result, operating results in any period are negatively affected
by expenditures for marketing and promotion. Since the Company's monthly
services are billed in advance, accounts receivable are relatively small.
 
     The Company capitalizes all installation costs (labor, subcontractor costs
and supplies). Such capitalized installation costs generally are amortized over
three years. Headend equipment is generally depreciated over ten years.
Equipment purchased and awaiting installation into subscriber premises is
classified as part of property and equipment in the Company's Consolidated
Financial Statements.
 
     Management believes that period-to-period comparisons of the Company's
financial results to date are not necessarily meaningful and should not be
relied upon as an indication of future performance due to the Company's
historically high growth rate and the number of system launches and acquisitions
during the periods presented.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  SOURCES AND USES OF FUNDS
 
     The Company has experienced negative cash flows from operations in each
year since its formation, and although certain of the Company's more established
systems currently generate positive cash flow from operations, the Company
expects to continue to experience negative consolidated free cash flow from
operations. Until sufficient cash flow is generated from operations, the Company
will be required to utilize its current capital resources or external sources of
funding to satisfy its working capital and capital expenditure needs.
 
     The Company expects that its principal capital expenditure requirements for
1997 will relate to replacement of customer churn, launch of high-speed Internet
services in one or more markets and the purchase of transmission equipment for
new channels. The Company intends to finance these capital expenditures from
existing cash and investment balances, borrowings under the Credit Facility, and
cash
 
                                       22
<PAGE>   24
 
generated from system operations. The commercial introduction by the Company of
digital services, such as digital video, high-speed Internet access and
telephony, would require substantial additional capital expenditures. While the
Company may use a portion of the proceeds from the BellSouth Transaction to
acquire assets for the development of such digital services, management does not
expect that such proceeds will be sufficient to fully implement its digital
strategies for video, Internet access and telephony throughout its markets. As
further described below, the Company is pursuing relationships or transactions
with other providers of telecommunications services to facilitate access to
additional capital, among other things. See "-- Strategic Relationship
Objectives." The Company's ability to fully implement its revised business
strategy will depend on its ability to attract sufficient additional capital
through relationships with strategic partners or otherwise. There can be no
assurance that sufficient capital will be available on terms satisfactory to the
Company, or at all.
 
     On March 18, 1997, the Company entered into the BellSouth Agreement, which
provides for the sale of all of the Company's Southeastern Assets to BellSouth
Wireless. The Southeastern Assets include operating wireless cable systems in
Orlando, Lakeland, Jacksonville, Daytona Beach and Ft. Myers, Florida and
Louisville, Kentucky and wireless cable channel rights in Bradenton, Naples,
Sebring and Miami, Florida. The purchase price for all of the Southeastern
Assets will range from $67.9 million to $103.2 million, depending upon the
number of wireless cable channel rights that are ultimately transferred to
BellSouth Wireless. See "Business -- Recent Development." The BellSouth
Agreement contains customary conditions to closing, including the expiration of
applicable waiting periods under the federal antitrust laws and the satisfaction
of all applicable regulatory requirements. There can be no assurance that all of
such conditions will be satisfied or that the BellSouth Transaction will be
consummated.
 
     To date, the Company's operations have required substantial amounts of
capital for (i) the installation of equipment in new subscribers' homes, (ii)
the construction of additional transmission and headend facilities and related
equipment purchases, (iii) the funding of start-up losses and other working
capital requirements, (iv) the acquisition of wireless cable channel rights and
systems, and (v) investments in, and maintenance of, vehicles and administrative
offices. The Company's capital expenditures, exclusive of acquisitions of
wireless cable systems and additions to deferred license and leased license
acquisition costs, during the years ended December 31, 1994, 1995 and 1996 were
approximately $35.5 million, $49.3 million, and $32.5 million, respectively.
Such expenditures were primarily for the construction and expansion of the
Company's wireless cable systems and the installation of equipment in new
subscribers' homes.
 
     In addition, the Company was involved in the bidding process for wireless
cable channel authorizations in certain basic trading areas ("BTAs"), which was
completed in March 1996. The Company was the highest bidder in 59 markets. In
the aggregate, the Company's bids in these markets totaled approximately $10.1
million. Of such amount, a total of approximately $9.3 million has been paid.
The remaining amount (approximately $800,000) is due upon the FCC's notification
to the Company of the issuance of the remainder of its BTA licenses, which the
Company expects will occur in 1997.
 
     On June 28, 1996, the Company entered into a definitive agreement to
acquire wireless cable channel rights and certain other subscription television
assets in Cincinnati, Ohio (the "Cincinnati Acquisition") for aggregate
consideration of approximately $5.2 million (of which approximately $3.5 million
had been paid as of January 31, 1997). Also on June 28, 1996, the Company
acquired certain of the Cincinnati subscription television assets and entered
into a management agreement to operate the subscription television assets that
it has not yet acquired. The subscription television assets acquired or to be
acquired by the Company in connection with the Cincinnati Acquisition served
approximately 3,100 subscribers as of the date of acquisition. Completion of the
Cincinnati Acquisition is subject to certain contingencies, such as FCC
approvals, the satisfactory completion of due diligence, and other customary
conditions to closing, which may or may not be satisfied. There can be no
assurance that the Cincinnati Acquisition will be consummated.
 
     In February 1996, $2.5 million of notes issued in connection with the
Company's September 1995 acquisition of Superchannels of Las Vegas, Inc. were
converted into 162,854 shares of ATI Common Stock. In May 1996, the Company
completed an offering of 1,700,000 shares of its Class A Common Stock resulting
in net proceeds of approximately $19.9 million. In August 1996, the Company
completed a private placement
 
                                       23
<PAGE>   25
 
of 100,000 shares of its Series B Convertible Preferred Stock, resulting in net
proceeds to the Company of $9.4 million. In October 1996, the Company completed
a private placement of 150,000 shares of its Series B Convertible Preferred
Stock, resulting in net proceeds to the Company of $14.3 million. During 1996,
the Company also completed the sale of wireless cable systems in St. James,
Minnesota and Yankton, South Dakota and wireless cable channel assets in Sioux
Falls, South Dakota for cash consideration totaling $3.1 million (of which
approximately $355,000 is being held in escrow pending completion of certain
post closing events).
 
     Under the terms of a Supplemental Indenture dated August 10, 1995,
governing the Company's Senior Discount Notes due 2004 (the "2004 Notes"), the
yield to maturity of the 2004 Notes was to be adjusted to 15 1/2% per annum
(from 14 1/2% per annum) if the Company did not, between August 10, 1995 and
November 10, 1996, issue equity securities having a value at the time of
issuance of at least $50.0 million in the aggregate. Subsequent to August 10,
1995, the Company issued equity securities which had an aggregate value at the
time of issuance in excess of $50.0 million. These issuances satisfied the
condition set forth in the Supplemental Indenture. Accordingly, the yield to
maturity of the 2004 Notes will remain at 14 1/2%.
 
  STRATEGIC RELATIONSHIP OBJECTIVES
 
     As described above, the Company will require significant additional capital
to fully implement its revised business strategy (including costs associated
with the provision of digital video service in certain of its Developed Markets
and the introduction of other digital wireless services such as high-speed
Internet access and telephony). To meet such capital requirements, the Company
is pursuing opportunities to enter into strategic relationships or transactions
with other providers of telecommunications services. Such relationships or
transactions could involve, among other things, joint ventures, sales or
exchanges of stock or assets, or loans to or investments in the Company by
strategic partners. As of the date of this Report, other than the BellSouth
Transaction, the Company has not reached any agreements or understandings with
respect to such relationships or transactions and there can be no assurance that
any such agreements or understandings will be reached.
 
  CREDIT FACILITIES
 
     Credit Facility
 
     On February 26, 1997, the Company entered into a $17.0 million credit
facility the ("Credit Facility") with Banque Indosuez, New York Branch (the
"Bank"). Proceeds of the Credit Facility are to be used to repay a portion of
the Company's existing debt, for capital expenditures, to complete certain
pending acquisitions of wireless cable channel rights, and for working capital
and other general corporate purposes.
 
     The term of the Credit Facility is up to twelve months. The loan must be
repaid earlier than the specified termination date and certain mandatory
prepayments must be made with proceeds from debt issuances or certain asset
sales, including the BellSouth Transaction. The Credit Facility bears interest
at a rate of 12.5%, which rate shall increase by 0.50% per quarter. Borrowings
under the Credit Facility are secured by a security interest in favor of the
Bank in substantially all of the assets of ATI and its subsidiaries. The Credit
Facility is further secured by a pledge of the stock of substantially all of
ATI's subsidiaries as well as a pledge of the note due to the Company from its
Fresno subsidiary under the Fresno Facility (as defined herein).
 
     The Company paid the Bank a commitment fee of $340,000. At closing, the
Company paid an additional fee of $340,000 and reimbursed the Bank for its out
of pocket expenses incurred in conjunction with the making of the loan. During
the term of the Credit Facility, the Company is required to pay to the Bank a
commitment commission on the unused loan balance at the annual rate of 0.50%.
 
     At closing, the Company also delivered 4,500 bond appreciation rights
("BARs") and an option to exercise 141,667 debt warrants or 141,667 equity
warrants. The debt warrants give the holder the right to increase the principal
amount of the loan by $6.00 per warrant, or the right to require the Company to
purchase the debt warrant for $6.00 per warrant. The debt warrants are
exercisable or puttable during a five-day period beginning on the earlier of one
year from the date of issuance, or notice that payment in full of
 
                                       24
<PAGE>   26
 
the Credit Facility has occurred or will occur shortly. The equity warrants give
the holder the right to purchase up to 141,667 shares of the Company's Class A
Common Stock for a price of $3.281 per share. Pursuant to the option agreement
relating to the warrants, the equity warrants become exercisable only to the
extent that the holder elects not to exercise or put the debt warrants or, if
the holder elects to put the debt warrants to the Company, the Company fails to
make payment therefor within the time required. Amounts payable in connection
with the BARs are based upon the appreciation in price of $4.5 million face
value of the Company's 2004 Notes. The BARs are exercisable after the earlier of
June 15, 1999 or the occurrence of an Event of Default under the 2004 Notes. The
payment due upon exercise of each BAR is equal to the market price of the 2004
Notes on the closing date less $290. The net value of the BARs is payable to
holders of the BARs in cash. The Company has deposited $1.0 million in escrow to
satisfy certain interest obligations under the Credit Facility.
 
     Fresno Facility
 
     During 1996, the Fresno Partnership maintained a revolving credit facility
(the "Fresno Facility") with a bank that provided for borrowings for the Fresno,
Visalia and Merced systems. However, no amounts were available for borrowing
under such facility as of December 31, 1996. Effective June 30, 1996, the Fresno
Facility was amended (the "Amended Agreement") to, among other things (i) permit
the incurrence by the Fresno Partnership of up to $2.3 million in subordinated
debt due ATI; (ii) permit the payment to ATI by the Fresno Partnership of a loan
fee of up to $23,000; and (iii) modify certain of the financial and other
operating covenants specified in the original agreement. In addition, past
violations of certain financial and other operating covenants associated with
the Fresno Facility were waived by the bank. In exchange for the bank's entering
into the Amended Agreement, the Fresno Partnership agreed to cause the bank's
participation in the Fresno Facility to be eliminated by March 31, 1997, through
prepayment by the Fresno Partnership of all amounts due, assignment of the
bank's participation to a third party lender or lenders (including ATI), or some
combination of the foregoing. In connection therewith, as of December 31, 1996
ATI had purchased, in the aggregate, a $5.5 million participation in the Fresno
Facility from the bank. In February 1997, ATI purchased the remaining $3.0
million participation in the Fresno Facility from the bank. As a result, the
Fresno Facility is now an obligation of the Fresno Partnership to ATI. The
Fresno Facility contains various financial and other restrictive covenants that,
among other things, prohibit the payment of dividends. As of December 31, 1996,
the Fresno Partnership was not in compliance with certain of the restrictive
covenants contained in the Fresno Facility. Outstanding borrowings under the
Fresno Facility bear interest at the banks' prime rate plus 2.25% (10.5% at
December 31, 1996). Interest expense relating to the Fresno Facility during the
year ended December 31, 1996 totaled $763,000. The Fresno Facility is secured by
the assets of the Fresno, Visalia and Merced systems.
 
  OTHER LIQUIDITY AND CAPITAL RESOURCES REQUIREMENTS AND LIMITATIONS
 
     As a result of certain limitations contained in the Indentures (the
"Indentures") relating to the 2004 Notes and the Company's 14.5% Senior Discount
Notes due 2005 (the "2005 Notes"), the Company's total borrowing capacity
outside the 2004 Notes and the 2005 Notes is currently limited to $17.5 million
and its additional borrowing capacity is currently limited to approximately $8.2
million. The Company expects that it will utilize the Credit Facility to borrow
all amounts that it is permitted to borrow under the terms of the Indentures.
Thus, the Company does not expect to be able to raise additional debt capital in
the foreseeable future. Moreover, under current market conditions, the Company
does not expect to be able to raise additional capital by issuing equity
securities. In the future, the issuance of moderate amounts of certain types of
new equity could, under Section 382 of the Internal Revenue Code, require the
Company to pay income taxes on gains received on asset sales because of the
Company's inability to fully offset such gains against net operating loss
carryforwards.
 
     The Company has taken certain actions aimed at reducing its costs and
conserving its capital, including reductions in the size of its workforce and
decreases in capital expenditures and discretionary expenses. As a result of
these actions, the Company currently expects that its existing cash and
investment balances, proceeds from the Credit Facility, and cash generated from
operations will be sufficient to finance its operations during
 
                                       25
<PAGE>   27
 
1997. Thereafter, additional financing will be required. If the Company's
capital resources are not sufficient to finance its operations, either in 1997
or thereafter, the Company will be required to curtail its operations and
development plans, which curtailment could involve, among other things, a
complete cessation of new customer additions. If the BellSouth Transaction or
any strategic relationships or transactions with other providers of
telecommunications services are consummated, the proceeds therefrom will provide
further resources to help finance the Company's operations and development
plans.
 
     Historically, the Company has generated operating and net losses on a
consolidated basis and can be expected to do so for the foreseeable future. Such
losses may increase as the Company's analog subscriber base declines, unless and
until the Company is able to successfully introduce other revenue-producing
wireless services. As a result of its history of net losses, the Company
currently has a negative tangible net worth and expects that negative
stockholders' equity will result before March 31, 1997. A negative tangible net
worth or stockholders' equity position has significant implications, including,
but not limited to, non-compliance with Nasdaq National Market listing criteria.
If the Company ceases to satisfy the Nasdaq National Market listing criteria,
its Class A Common Stock will be subject to delisting, unless an exception is
granted by the National Association of Securities Dealers. If an exception is
not granted, trading in the Company's Class A Common Stock would thereafter be
conducted in the over-the-counter market. Consequently, it would be more
difficult to dispose of, or to obtain accurate quotations as to the price of the
Class A Common Stock. Delisting could result in a decline in the trading market
for the Class A Common Stock, which could potentially depress the Company's
stock and bond prices, among other things. The Company believes that the
proceeds of the BellSouth Transaction, if consummated, will help bring the
Company into compliance with the Nasdaq National Market listing criteria.
However, there can be no assurance that the Company will be able to achieve or
sustain positive tangible net worth, stockholders' equity or net income in the
future.
 
RESULTS OF OPERATIONS
 
  Fiscal Year 1996 Compared to Fiscal Year 1995
 
     Service revenues increased $14.5 million, or 31.4%, during the year ended
December 31, 1996 to $60.7 million, as compared to $46.2 million during the year
ended December 31, 1995. This increase resulted primarily from the addition of
new subscribers. Subscriber increases resulted primarily from the 1996
acquisition of subscription television subscribers in Cincinnati, the 1995
acquisitions of the Redding, Las Vegas and Rapid City systems, and the
completion of construction and commencement of operation of systems in Yuba City
and Lincoln during 1995 and Anchorage and Portland during 1996. Service price
increases contributed only a small portion of the aggregate increase in service
revenues. The number of subscribers to the Company's wireless cable systems
increased to 179,800 at December 31, 1996, compared to 173,700 at December 31,
1995.
 
     On a "same system" basis (comparing systems that were operational for all
of each of the years ended December 31, 1996 and 1995), service revenues
increased $6.7 million, or 16.9%, to $46.3 million during the year ended
December 31, 1996, as compared to $39.6 million for the year ended December 31,
1995. Same systems during these periods totaled 24 systems. The average number
of same-system subscribers increased approximately 13.2% during the year ended
December 31, 1996, as compared to the year ended December 31, 1995.
 
     Installation revenues totaled $1.3 million in each of the years ended
December 31, 1996 and 1995. The number of installations completed during the
year ended December 31, 1996 decreased approximately 22.0% as compared to the
year ended December 31, 1995. However, this decrease was fully offset by less
discounting of installation rates. Installation rates vary widely by system
based upon competitive conditions. The Company occasionally reduces installation
charges as part of selected promotional campaigns.
 
     Operating expenses, principally programming, site costs and other direct
expenses, aggregated $36.0 million (or 58.1% of total revenues) during the year
ended December 31, 1996, compared to $26.0 million (or 54.8% of total revenues)
during the year ended December 31, 1995. The increase of $10.0 million was
primarily the result of additional systems and subscribers, as well as increased
programming costs for additions to channel line-ups and increased pay-per-view
offerings in various systems.
 
                                       26
<PAGE>   28
 
     Marketing and selling expenses totaled $7.4 million (or 12.0% of total
revenues) during the year ended December 31, 1996, compared to $8.7 million (or
18.3% of total revenues) during the year ended December 31, 1995. The decrease
in such expenses of $1.3 million resulted from decreased marketing activity, net
of marketing expenses associated with the addition of new systems. During the
year ended December 31, 1996, general and administrative expenses totaled $18.8
million (or 30.4% of total revenues), a $400,000 decrease over the year ended
December 31, 1995 ($19.2 million or 40.4% of total revenues). The decrease in
general and administrative expenses principally resulted from reductions in the
number of employees and certain non-recurring expenses totaling $1.1 million
recognized during 1995 relating to the recognition of certain lease termination
and severance costs. Such decreases were partially offset by increased general
and administrative expenses associated with the addition of new systems.
 
     In the fourth quarter of 1996, after considering the Company's 1996
operating loss, its history of such operating losses and the expectation of
future operating losses, changes in the Company's strategic direction,
developments relating to previously scheduled industry transactions and
ventures, and the industry factors described above under
"Business -- Regulation" and "Business -- Competition", the Company evaluated
the ongoing value of its wireless cable business in each Developed Market. Based
on this valuation, the Company determined that assets with a carrying value of
$95.1 million were impaired according to the provisions of Statement of
Financial Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to be Disposed Of," and wrote
down the carrying value of such assets by $21.3 million to their fair value. An
evaluation was made for each of the Company's Developed Markets individually,
not for the Company's markets as a whole. Fair value was based on recent
transactions in the wireless cable industry. In addition, during the fourth
quarter of 1996, the Company prospectively revised the lives of its subscriber
premise equipment from seven years to three or four years.
 
     The Company's loss from operations was $66.2 million during the year ended
December 31, 1996, as compared to $35.7 million during the year ended December
31, 1995. The increase in the loss from operations of $30.5 million during 1996
resulted primarily from the impairment loss of $21.3 million described above and
increased depreciation and amortization expense. Depreciation and amortization
expense (principally depreciation of property and equipment and amortization of
deferred license and leased license acquisition costs, goodwill and covenants
not-to-compete) increased $15.4 million in the year ended December 31, 1996,
compared to the year ended December 31, 1995, due to increases in deferred
license costs, goodwill and subscriber equipment resulting from the acquisition
and addition of new systems and the addition of equipment installed in new
subscribers' homes.
 
     Interest expense increased $12.8 million during the year ended December 31,
1996 to $37.3 million, as compared to $24.5 million during the year ended
December 31, 1995. The increase in interest expense primarily resulted from
noncash interest charges associated with the Company's 2004 Notes and 2005
Notes. Interest expense associated with the 2004 Notes also increased due to an
increase in the interest rate on the 2004 Notes from 12.5% to 14.5% effected in
August 1995 in conjunction with the Company's offering of the 2005 Notes.
 
     Loss before interest, taxes, depreciation and amortization and the
impairment write down described above totaled $253,000 for the year ended
December 31, 1996, as compared to a loss before interest, taxes, depreciation,
and amortization of $6.4 million during the year ended December 31, 1995.
 
  Fiscal Year 1995 Compared to Fiscal Year 1994
 
     Service revenues increased $25.5 million, or 122.5%, during the year ended
December 31, 1995 to $46.2 million, as compared to $20.7 million during the year
ended December 31, 1994. This increase resulted primarily from the addition of
new subscribers. Subscriber increases resulted not only from the 1994
acquisitions of the Bend, FEN/WEN Group, Oklahoma City, Wichita and Lakeland
systems, the 1995 acquisitions of the Medford, Sheridan, Fresno, Visalia,
Merced, Redding, Las Vegas and Rapid City systems, and the commencement of
operations in Columbus, Youngstown, Jacksonville, Lansing and Monterey during
1994 and Ft. Collins, Greeley, Yuba City, and Lincoln during 1995, but also from
increased marketing and promotional efforts in all markets. Service price
increases contributed only a small portion of the aggregate
 
                                       27
<PAGE>   29
 
increase in service revenues. The number of subscribers to the Company's
wireless cable systems increased to approximately 173,700 at December 31, 1995
compared to approximately 106,500 at December 31, 1994.
 
     On a "same system" basis (comparing systems that were operational for all
of each of the years ended December 31, 1994 and 1995), service revenues
increased $8.0 million, or 57.5%, to $21.9 million for the year ended December
31, 1995, as compared to $13.9 million for the year ended December 31, 1994.
This increase resulted primarily from the addition of new subscribers. Same
systems during this period consisted of the Company's Colorado Springs, Orlando,
Ft. Myers, Billings, Toledo, Daytona Beach, Michiana, Denver, Little Rock and
Louisville systems. The number of subscribers in these systems increased
approximately 40.7% during the year ended December 31, 1995.
 
     Installation revenues for the year ended December 31, 1995 totaled $1.3
million, as compared to $871,000 during the year ended December 31, 1994. The
increase in installation revenues of $441,000, or 50.6%, was primarily the net
result of more subscriber installations in each system, less the effect of lower
per-subscriber installation charges in certain systems.
 
     Operating expenses aggregated $26.0 million (or 54.8% of total revenues)
during the year ended December 31, 1995, as compared to $13.1 million (or 60.7%
of total revenues) during the year ended December 31, 1994. The increase of
$12.9 million was primarily the result of additional systems and subscribers as
well as increased programming costs from additions to channel line-ups in
various systems. In 1995, the Company began capitalizing all subscriber
installation costs. Previously, the Company expensed an amount equal to
installation revenues and capitalized installation costs in excess of
installation revenues. This change in accounting method was effected to better
match installation costs with related subscriber service revenues. Operating
expenses for the year ended December 31, 1994 include installation costs which
were expensed of approximately $871,000.
 
     Marketing and selling expenses totaled $8.7 million (or 18.3% of total
revenues) during the year ended December 31, 1995, as compared to $4.1 million
(or 18.8% of total revenues) during the year ended December 31, 1994. The
increase in such expenses of $4.6 million resulted primarily from the addition
of new systems, intensified sales and marketing efforts (including the
introduction of the WANTV(SM) brand name in certain of the Company's systems),
and from increased media spending. During 1995, general and administrative
expenses totaled $19.2 million (or 40.4% of total revenues), a $9.8 million
increase over the year ended December 31, 1994 (43.6% of total revenues). This
increase resulted not only from the addition of new systems and increased
corporate and regional overhead expenses, but also from the recognition of
severance costs totaling $711,000 and lease termination costs of $420,000
related to the relocation of the Company's corporate headquarters to larger
office space in Colorado Springs.
 
     The Company's loss from operations was $35.7 million during the year ended
December 31, 1995, as compared to $17.0 million during the year ended December
31, 1994. The increase in the loss from operations of $18.7 million resulted
from increased depreciation and amortization expense, as well as from the
increases in marketing and general and administrative expenses described above.
Depreciation and amortization expense (principally depreciation of property and
equipment and amortization of deferred license and leased license acquisition
costs, goodwill and covenants not-to-compete) increased $17.2 million due to
increases in deferred license costs, goodwill and subscriber equipment resulting
from the acquisition and addition of new systems and the addition of equipment
installed in new subscribers' homes. Approximately $644,000 of the increase in
depreciation and amortization expenses was attributable to the change in
accounting for installation costs previously described.
 
     Interest expense increased $15.2 million during the year ended December 31,
1995 to $24.5 million, as compared to $9.3 million during the year ended
December 31, 1994. The increase in interest expense primarily resulted from
noncash interest charges associated with the 2004 Notes and 2005 Notes and
additional borrowings under, and higher interest rates associated with, the
Company's various revolving credit facilities. The Company's loss before
interest, taxes, depreciation and amortization totaled $6.4 million for the year
ended December 31, 1995, as compared to $5.0 million during the year ended
December 31, 1994 (a pro forma amount of $4.1 million assuming the change in
accounting method was applied retroactively). The increase in the loss before
interest, taxes, depreciation and amortization of $1.4 million primarily
resulted from
 
                                       28
<PAGE>   30
 
proportionately larger start-up losses of the Company's systems that commenced
operation during 1994, pre-opening costs and start-up losses of the Company's
systems that commenced operations during 1995, increased marketing expenses, and
increased corporate overhead related to significant system development and
market expansion activities. Such increases were partially offset by improved
operating results from growth in the Company's other systems. The Medford,
Sheridan, Redding, Fresno, Visalia, Merced, Las Vegas and Rapid City systems
acquired during 1995 generated, in the aggregate, earnings before interest,
taxes, depreciation and amortization of $1.3 million. Excluding these
acquisitions, the Company's loss before interest, taxes, depreciation and
amortization for the year ended December 31, 1995 approximated $7.7 million.
 
INCOME TAX MATTERS
 
     ATI and its subsidiaries file a consolidated federal tax return. The
Company has had no state or federal income tax expense since inception. As of
December 31, 1996, the Company had approximately $156.6 million in net operating
loss carryforwards for tax purposes, expiring through 2011. Section 382 of the
Internal Revenue Code limits the amount of loss carryforwards that a company can
use to offset future income upon the occurrence of certain changes in ownership.
The issuance of moderate amounts of certain types of new equity could limit the
Company's ability to use net operating losses to offset future gains from the
sale of assets, thus requiring the Company to pay income taxes on gains received
in such asset sales.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
     In March 1995, the Financial Accounting Standards Board (the "FASB") issued
SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of," which requires impairment losses to be
recognized for long-lived assets used in operations when indicators of
impairment are present and the future undiscounted cash flows are not sufficient
to recover the assets' carrying amount. The resultant impairment loss is
measured by comparing the fair value of the asset to its carrying amount. The
Company adopted SFAS No. 121 in the first quarter of 1996. SFAS No. 121 did not
have a material effect on the Company's financial position or results of
operations at the time of adoption. As previously described, during the fourth
quarter of 1996, the Company determined that indicators of impairment were
present. As a result, a charge of $21.3 million was recognized to write down the
carrying value of certain assets to their fair value.
 
     The Company follows the guidelines established by Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations in accounting for its employee stock options. In October 1995,
the FASB issued SFAS No. 123, "Accounting and Disclosure of Stock-Based
Compensation," which established an alternative method of expense recognition
for stock-based compensation awards to employees based on fair values. The
Company elected not to adopt the statement for expense recognition purposes.
 
     On March 3, 1997, the FASB released SFAS No. 128, "Earnings Per Share."
SFAS No. 128 requires dual presentation of basic and diluted earnings per share
on the face of the income statement for all periods presented. Basic earnings
per share excludes dilution and is computed by dividing income available to
common stockholders by the weighted-average number of common shares outstanding
for the period. Diluted earnings per share reflects the potential dilution that
could occur if securities or other contracts to issue common stock were
exercised or converted into common stock or resulted in the issuance of common
stock that then shared in the earnings of the entity. Diluted earnings per share
is computed similarly to fully diluted earnings per share pursuant to Accounting
Principles Bulletin No. 15. SFAS No. 128 is effective for fiscal years ending
after December 15, 1997, and when adopted, it will require restatement of prior
years' earnings per share.
 
     Since the effect of outstanding options is antidilutive, they have been
excluded from the Company's computation of net loss per share. Accordingly,
management does not believe that SFAS No. 128 will have an impact upon
historical net loss per share as reported.

INFLATION
 
     Inflation has not affected the Company's operations significantly during
the past three years. The Company believes that its ability to increase charges
for services in future periods will depend primarily on competitive pressures.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To American Telecasting, Inc.:
 
     We have audited the accompanying consolidated balance sheets of American
Telecasting, Inc. (a Delaware corporation) and subsidiaries as of December 31,
1995 and 1996, and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1996. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of American Telecasting, Inc.
and subsidiaries as of December 31, 1995 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BUSINESS DESCRIPTION
 
  Organization
 
     American Telecasting, Inc. ("ATI") owns and operates a network of wireless
cable television systems providing subscription television service to
residential and commercial customers. ATI and its subsidiaries are collectively
referred to herein as the "Company." As of December 31, 1995 and 1996, the
Company owned and operated 38 wireless cable systems located throughout the
United States (the "Developed Markets"). The Company also has significant
wireless cable (microwave) frequency interests in 16 other U.S. markets (the
"Undeveloped Markets").
 
  Risks and Other Important Factors
 
     Since inception, the Company has focused principally on developing wireless
cable systems to provide multiple channel television programming. During 1996,
the Company's business strategy evolved to adapt to the significant regulatory
and technological changes that have occurred recently in the telecommunications
industry and to the Company's capital constraints. Management now believes that
the most promising use of the Company's wireless assets may be to provide a
variety of digital wireless services, instead of the traditional analog-based
technology utilized by the Company to date. Such digital wireless services could
include digital video (i.e., subscription television), high-speed Internet
access and telephony services. While the Company has begun planning and testing
of these digital wireless services, it has not yet introduced any of these
services. The Company's ability to introduce these services on a commercial
basis will depend on a number of factors, including the availability of
sufficient capital, the success of the Company's development efforts,
competitive factors (such as the introduction of new technologies or the entry
of competitors with significantly greater resources than the Company), the level
of consumer demand for such services, the availability of appropriate
transmission and reception equipment on satisfactory terms, and the Company's
ability to obtain the necessary regulatory changes and approvals. The Company
expects that the market for any such additional services will be extremely
competitive.
 
     Since early 1996, the Company has taken certain actions aimed at reducing
its costs and conserving its capital. Such measures include reductions in the
size of the Company's workforce and decreases in capital expenditures and
discretionary expenses. During 1997, the Company does not plan to make the
capital expenditures necessary to add enough subscribers to replace those
subscribers who choose to stop receiving the Company's service. Moreover, at
this time, the Company does not generally intend to further develop any of its
Undeveloped Markets using analog technology. Thus, the Company anticipates that
its analog customer base will decrease somewhat during 1997. As the Company's
analog subscriber base decreases, its revenues are expected to decrease unless
and until it is able to successfully introduce other revenue-producing wireless
services, such as digital video, high-speed Internet access and telephony. The
Company currently expects that its existing cash and investment balances,
proceeds from the Facility (see Note 7) and cash generated from operations will
be sufficient to finance its operations during 1997. Thereafter, additional
financing will be required. If the Company's capital resources are not
sufficient to finance its operations, either in 1997 or thereafter, the Company
will be required to curtail its operations and development plans, which
curtailment could involve, among other things, a complete cessation of new
customer additions. Any proceeds received by the Company from the BellSouth
Transaction (as defined below) will provide further resources to help finance
the Company's operations and development plans.
 
     The Company will require significant additional capital to fully implement
its digital strategy. To meet such capital requirements, the Company is pursuing
opportunities to enter into strategic relationships or transactions with other
providers of telecommunications services. Such relationships or transactions
could involve, among other things, joint ventures, sales or exchanges of stock
or assets, or loans to or investments in the Company by strategic partners. As
of the date of this Report, except for the BellSouth Transaction, the

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Company has not reached any agreements or understandings with respect to such
relationships or transactions and there can be no assurance that any such
agreements or understandings will be reached.
 
     Interest payments on the Company's 2004 Notes and 2005 Notes will commence
on December 15, 1999 and February 15, 2001, respectively. Interest payments in
1999, 2000, and 2001 are expected to be approximately $14.3 million, $28.5
million and $59.1 million, respectively.
 
  Recent Development
 
     On March 18, 1997, the Company entered into a definitive agreement with
BellSouth Corporation and BellSouth Wireless Corporation ("BellSouth Wireless")
providing for the sale of all of the Company's Florida and Louisville, Kentucky
wireless cable assets (the "Southeastern Assets") to BellSouth Wireless (the
"BellSouth Transaction"). Depending upon the number of wireless cable channel
rights that are ultimately transferred to BellSouth Wireless, the purchase price
will range from $67.9 million to $103.2 million. A first closing is expected to
occur when all necessary third party and governmental consents to the assignment
of a minimum number of channel positions in Orlando, Jacksonville, Daytona
Beach, Ft. Myers, Miami, Lakeland, Bradenton and Louisville have been obtained,
which the Company expects will occur prior to the end of the fourth quarter of
1997. The remainder of the Southeastern Assets will be sold upon the
satisfaction of certain closing conditions that are specific to the markets
involved, but in no event later than two years after the date of the first
closing. The agreement contains customary conditions to closing, including the
expiration of applicable waiting periods under the federal antitrust laws and
the satisfaction of all applicable regulatory requirements. There can be no
assurance that all of such conditions will be satisfied or that the BellSouth
Transaction will be consummated.
 
     The Company also has granted to BellSouth Wireless an option to purchase
for $9.0 million the Company's wireless cable channel rights in Yuba City,
California and the Company's Yuba City and Sacramento, California BTA
authorizations. The option can be exercised by BellSouth Wireless at any time
within 18 months after the date of the agreement.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of ATI and its
subsidiaries. All significant intercompany accounts and transactions have been
eliminated.
 
  Use of Estimates in Preparation of Financial Statements
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Cash and Cash Equivalents
 
     The Company considers all short-term investments with original maturities
of 90 days or less to be cash equivalents. As of December 31, 1995 and 1996,
cash equivalents principally consisted of money market funds, commercial paper,
federal government/agency debt securities, and other short-term,
investment-grade, interest-bearing securities. The carrying amounts reported in
the balance sheet for cash and cash equivalents approximate the fair values of
those assets.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Long-Lived Assets
 
     Long-lived assets and identifiable assets to be held and used are reviewed
for impairment whenever events or changes in circumstances indicate that the
carrying amount should be addressed. Impairment is measured by comparing the
carrying value to the estimated undiscounted future cash flows expected to
result from the use of the assets and their eventual dispositions for each of
the Company's markets. The Company considers relevant cash flow, estimated
future operating results, trends and other available information including the
fair value of frequency rights owned, in assessing whether the carrying value of
the asset can be recovered.
 
     In the fourth quarter of 1996, after considering the Company's 1996
operating loss, its history of such operating losses and the expectation of
future operating losses, changes in the Company's strategic direction,
developments relating to previously scheduled industry transactions and ventures
and certain industry factors, the Company evaluated the ongoing value of its
wireless cable business in each Developed Market. Based on this valuation, the
Company determined that assets with a carrying value of $95.1 million were
impaired according to the provisions of SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of",
and wrote down the carrying value of such assets by $21.3 million to their fair
value. An evaluation was made for each of the Company's Developed Markets
individually, not for the Company's markets as a whole. Fair value was based on
recent transactions in the wireless cable industry.
 
     The Company's estimates of anticipated gross revenues, the remaining
estimated lives of tangible and intangible assets, or both, could be reduced
significantly in the future due to changes in technology, regulation, available
financing or competitive pressures in any of the Company's individual markets.
As a result, the carrying amount of long-lived assets and intangibles including
goodwill could be reduced materially in the future.
 
          Property and Equipment. Property and equipment are stated at cost.
     Depreciation and amortization, including amortization of assets acquired
     under capitalized lease agreements, are recorded on a straight-line basis
     for financial reporting purposes. Repair and maintenance costs are charged
     to expense when incurred. Renewals and betterments are capitalized.
     Subscriber installation costs are capitalized and amortized over a three
     year period, the approximate average subscription term of a subscriber.
     Prior to January 1, 1995, the Company expensed subscriber installation
     costs to the extent of installation revenues and capitalized installation
     costs in excess of installation revenues. The cumulative effect of this
     change in accounting method for the periods prior to January 1, 1995 was a
     reduction in the Company's net loss of approximately $602,000, net of
     deferred income taxes of approximately $369,000. The effect of this change
     on the Company's results of operations for the year ended December 31, 1995
     was to decrease the net loss before cumulative effect of change in
     accounting method by approximately $668,000. Pro forma net loss and net
     loss per share for the years ended December 31, 1994 and 1995, assuming the
     change in accounting for installation costs was applied retroactively, were
     $(15,352,000) and $(1.07), and $(67,237,000) and $(4.21), respectively.
 
          Deferred License and Leased License Acquisition Costs. Deferred
     license and leased license acquisition costs include costs incurred to
     develop or acquire wireless cable licenses. Costs incurred to acquire or
     lease licenses issued by the Federal Communications Commission ("FCC") are
     deferred and are amortized ratably over useful lives of 20 years beginning
     with inception of service in each respective market, or charged to expense
     if development is not pursued. As of December 31, 1996, approximately $15.8
     million of the Company's deferred license and leased license acquisition
     costs were not yet subject to amortization. Accumulated amortization
     related to deferred license and leased license acquisition costs
     approximated $7.7 million and $14.9 million at December 31, 1995 and 1996,
     respectively.

          Goodwill. Goodwill is amortized on a straight-line basis for financial
     reporting purposes over a period of 20 years. Accumulated amortization
     related to goodwill was approximately $1.3 million and $2.2 million at
     December 31, 1995 and 1996, respectively.
 
          Deferred Financing Costs. Deferred financing costs represent fees and
     other costs incurred in connection with the issuance of long-term debt.
     These costs are amortized over the term of the related debt using the
     effective interest rate method.
 
     Other Assets. Other assets, net of accumulated amortization, consist of the
following (in thousands):

</TABLE>
 
     Covenants not-to-compete are amortized over their respective terms, which
is typically three years. Accumulated amortization related to covenants
not-to-compete and other intangible assets was $2.5 million and $3.6 million as
of December 31, 1995 and 1996, respectively.
 
  Revenue Recognition
 
     Monthly service fees are recognized in the period service is provided.
Installation revenue is recognized upon origination of service to a customer to
the extent of direct selling costs incurred. To date, direct selling costs have
exceeded installation revenues.
 
  Operating Costs and Expenses
 
     Operating costs and expenses consist principally of programming fees,
channel lease costs, tower rental and other costs of providing services. The
Company capitalizes certain pre-launch costs for non-operating systems. These
costs include tower and site rentals and channel lease payments. The total of
such costs capitalized in 1994, 1995 and 1996 approximated $163,000, $411,000
and $445,000, respectively.
 
  Marketing and Direct Selling Costs
 
     Marketing and direct selling costs are expensed as incurred.
 
  Net Loss Per Share
 
     Net loss per share is computed on the weighted-average number of common
shares outstanding for the respective periods. All Common Stock equivalents are
excluded as they are antidilutive. Fully diluted loss per share is not presented
as it would not materially differ from primary loss per share.
 
     Pursuant to the requirements of the Securities and Exchange Commission,
Common Stock issued by the Company during the 12 months immediately preceding
the Company's initial public offering (see Note 8), plus the number of Common
Stock equivalent shares which became issuable during the same period, were
treated as if they were outstanding for all periods presented prior to the
offering using the Treasury Stock method. The effect of other Common Stock
equivalents for periods prior to the offering have been excluded from the
calculation as their effect would be antidilutive. Historical net loss per share
and weighted-average number of shares outstanding were $(1.08) and 14,357,116
for the year ended December 31, 1994. The number of pro forma weighted-average
shares outstanding is computed as described above and also gives

effect to the conversion in January 1994 of all outstanding shares of Series A
Convertible Preferred Stock into 2,014,098 shares of Common Stock.
 
     In 1997, the Financial Accounting Standards Board released SFAS No. 128,
"Earnings Per Share." SFAS No. 128 requires dual presentation of basic and
diluted earnings per share on the face of the income statement for all periods
presented. Basic earnings per share excludes dilution and is computed by
dividing income available to common stockholders by the weighted-average number
of common shares outstanding for the period. Diluted earnings per share reflects
the potential dilution that could occur if securities or other contracts to
issue common stock were exercised or converted into common stock or resulted in
the issuance of common stock that then shared in the earnings of the entity.
Diluted earnings per share is computed similarly to fully diluted earnings per
share pursuant to Accounting Principles Bulletin No. 15. SFAS No. 128 is
effective for fiscal years ending after December 15, 1997, and when adopted, it
will require restatement of prior years' earnings per share.
 
     Since the effect of outstanding options is antidilutive, they have been
excluded from the Company's computation of net loss per share. Accordingly,
management does not believe that SFAS No. 128 will have an impact upon
historical net loss per share as reported.
 
  Reclassifications
 
     Certain amounts from the prior years' consolidated financial statements
have been reclassified to conform with the 1996 presentation.
 
  Supplemental Cash Flow Disclosures
 
     Noncash investing and financing activities consisted of the acquisition of
vehicles and equipment by acceptance of bank notes, capitalized leases and other
financing arrangements totaling approximately $992,000, $1.9 million, and
$604,000 during 1994, 1995 and 1996, respectively. Cash paid during 1994, 1995
and 1996 for interest approximated $2.0 million, $2.9 million and $2.0 million,
respectively. As discussed in Notes 3 and 7, the Company acquired property and
equipment, leased licenses, covenants not-to-compete and other assets in
acquisitions for notes totaling $6.8 million, Class A Common Stock valued at
$19.9 million and assumed liabilities of approximately $1.5 million during the
year ended December 31, 1994; notes totaling $3.8 million, Class A Common Stock
valued at $15.8 million, assumption of certain liabilities totaling $11.2
million during the year ended December 31, 1995, and Class A Common Stock valued
at $707,000 during the year ended December 31, 1996. During 1994, 1995 and 1996,
the Company acquired certain wireless cable channel rights for which the final
purchase consideration of approximately $1.7 million, $1.1 million and $1.0
million, respectively, was payable upon the FCC's consent to the assignment of
such licenses (see Note 6). Of such amounts, approximately $1.0 million remained
payable at December 31, 1996.
 
3. ACQUISITIONS AND DIVESTITURES
 
  1994 Acquisitions
 
     During 1994, the Company acquired wireless cable systems in Bend, Oregon
(from Central Vision, Inc.), a total of seven operating wireless cable systems
operating in Minnesota, Nebraska, North Dakota, South Dakota and Wisconsin (the
"FEN/WEN Group") (from Family Entertainment Network, Inc. and Wireless
Entertainment Network, Inc.), Oklahoma City, Oklahoma and Wichita, Kansas (from
Multimedia Cablevision, Inc.), and Lakeland, Florida (from People's Cable,
Inc. -- "People's Cable"). In addition, the Company acquired wireless cable
frequency rights in a number of other U.S. markets in connection with the
acquisition of the FEN/WEN Group. The aggregate purchase price for these
acquisitions of approximately $80.6 million was paid through a combination of
cash ($53.4 million, of which approximately $6.8 million was funded from the
proceeds of debt -- see Note 7), shares of ATI Common Stock (1,151,950 shares
valued at approximately

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
$19.7 million), and assumption of certain liabilities (approximately $7.5
million, of which approximately $6.0 million was retired immediately subsequent
to closing). In addition, the Company recognized a deferred income tax liability
of approximately $5.0 million for the excess of the value allocated to certain
of the assets acquired over their related tax basis.
 
  1995 Acquisitions
 
     During 1995, the Company acquired wireless cable systems in Medford, Oregon
(from Cardiff Communications Partners III), Sheridan, Wyoming (from Cardiff
Communications Partners I), Redding, California (from the Cardiff Communications
Partners IV), and Rapid City, South Dakota (from Rapid Choice TV, Inc.). Also
during 1995, the Company acquired Fresno Wireless Cable Television, Inc.
("FWCTI") and a 58% ownership interest in Superchannels of Las Vegas, Inc.
("Superchannels"). FWCTI is the 65% general partner of Fresno MMDS Associates
which owns wireless cable systems and frequency rights in the Fresno, Visalia
and Merced, California markets. Superchannels operates a wireless cable system
in the Las Vegas, Nevada market. The aggregate purchase price for these
acquisitions of approximately $46.7 million was paid through a combination of
cash ($16.5 million), notes ($3.8 million), shares of ATI Common Stock
(approximately 964,000 shares valued at approximately $15.2 million), and
assumption of certain liabilities (approximately $11.2 million). In addition,
the Company recognized a deferred income tax liability of approximately $6.3
million for the excess of the value allocated to certain of the assets acquired
over their related tax basis. In February 1996, $2.5 million of the notes issued
in connection with the acquisition of the Las Vegas system were converted into
162,854 shares of ATI Common Stock.
 
     All of the Company's acquisitions have been accounted for as purchases for
financial reporting purposes. The Company's consolidated statements of
operations for the years ended December 31, 1994 and 1995 include the results of
operations for each of the entities described above from their respective
acquisition dates. The aggregate purchase prices for the acquisitions completed
during 1994 and 1995 were allocated as follows (in thousands):

     During 1996, the Company acquired certain subscription television assets in
Cincinnati, Ohio for aggregate consideration of approximately $2.2 million and
wireless cable channel rights in various markets for aggregate consideration of
$1.1 million. The Company also acquired the remaining interest in its Little
Rock, Arkansas operating system for $707,000 in Class A Common Stock. Also
during 1996, the Company sold its wireless cable systems in St. James, Minnesota
and Yankton, South Dakota and its wireless cable channel assets in Sioux Falls,
South Dakota for aggregate cash consideration totaling $3.1 million (of which
approximately $355,000 is being held in escrow pending completion of certain
post-closing events). On June 28, 1996 the Company entered into a definitive
agreement to acquire wireless cable assets in Cincinnati, Ohio for approximately
$3.0 million. The pro forma effects of 1996 acquisitions and divestitures on
revenues, net loss and net loss per share as if such acquisitions and
divestitures had been made as of the beginning of the year are not presented as
they do not differ materially from historical results. During the years ended
December 31, 1994 and 1995, the Company acquired wireless cable channel rights
in various markets for aggregate consideration of $186,000 (Class A Common
Stock) and $7.0 million (cash -- $6.3 million and Class A Common Stock valued at
$653,000), respectively.
 
     The Company was involved in the bidding process for wireless cable channel
authorizations in certain basic trading areas ("BTAs"), which was completed in
March 1996. The Company was the highest bidder in 59 markets. In the aggregate,
the Company's bids in these markets totaled approximately $10.1 million. Of such
amount, a total of approximately $9.3 million has been paid. The remaining
amount (approximately $800,000) is due upon the FCC's notification to the
Company of the issuance of the remainder of its BTA licenses, which the Company
expects will occur in 1997.

     During the fourth quarter of 1996, the Company prospectively revised the
lives of its subscriber premise equipment to three to four years. As described

direction and certain industry factors. The revision decreased net income for
the year ended December 31, 1996 by approximately $600,000.

  Senior Discount Notes
 
     On June 23, 1994, ATI issued Units (the "1994 Units Offering") consisting
of Senior Discount Notes due 2004 (the "2004 Notes") which mature on June 15,
2004 and warrants to purchase Common Stock. The 1994 Units Offering resulted in
net proceeds to the Company of approximately $100.1 million (including amounts
attributable to the issuance of the 1994 Warrants (see Note 8) and before
payment of underwriting discounts and other issuance costs aggregating
approximately $4.4 million). On August 10, 1995, ATI issued Units (the "1995
Units Offering") consisting of Senior Discount Notes due 2005 (the "2005 Notes")

mature on August 15, 2005 and warrants to purchase Common Stock. The 1995 Units
Offering resulted in net proceeds to the Company of approximately $94.9 million,
including amounts attributable to the issuance of the 1995 Warrants (see Note
8), and after payment of underwriting discounts and other issuance costs
aggregating approximately $5.1 million.
 
     The 2004 Notes bear interest at a rate of 14.5%, computed on a semi-annual
bond equivalent basis. The aggregate principal balance at stated maturity of the
2004 Notes approximates $196.9 million. Cash interest will not be payable on the
2004 Notes prior to June 15, 1999. Commencing December 15, 1999, cash interest
on the 2004 Notes will be payable on June 15 and December 15 of each year at a
rate of 14.5% per annum.
 
     The issue price of the 2005 Notes represents a yield to maturity of 14.50%
per annum computed on a semi-annual bond equivalent basis. Cash interest will
not be payable on the 2005 Notes prior to August 15, 2000. Commencing February
15, 2001, cash interest on the 2005 Notes will be payable on February 15 and
August 15 of each year at a rate of 14.50% per annum. The 2005 Notes have an
aggregate principal balance at stated maturity of $201.7 million.
 
     Both the 2004 Notes and the 2005 Notes are effectively subordinated to all
indebtedness of ATI's subsidiaries, including trade payables, and rank pari
passu with all existing and future unsubordinated and unsecured indebtedness of
ATI.
 
     Both the 2004 Notes and the 2005 Notes were issued pursuant to Indentures
which contain certain restrictive covenants and limitations. Among other things,
the Indentures limit the incurrence of additional debt, limit the making of
restricted payments (as defined) including the declaration and/or payment of
dividends, place limitations on dividends and other payments by ATI's
subsidiaries, prohibit ATI and its subsidiaries from engaging in any business
other than the transmission of video, voice and data and related businesses and
services, and place limitations on liens, certain asset dispositions and
merger/sale of assets activity.
 
     Pursuant to the Indentures, the Company may not incur additional debt,
other than Permitted Debt (as defined), unless after giving effect to the
incurrence of such debt and the receipt and application of the net proceeds
thereof on a pro forma basis, the Company's consolidated debt to annualized
operating cash flow (as defined) ratio would be less than 5.0 to 1.0 in the case
of any such incurrence. Permitted Debt is defined as (a) the 2004 Notes and the
2005 Notes; (b) debt of up to $100.0 million in aggregate principal amount lent
by a strategic equity investor (as defined), provided, that such debt (i) is
subordinated in right of payment to the prior payment in full of all obligations
(including principal, interest and premium, if any) of the Company under the
2004 Notes and the 2005 Notes and related Indentures, (ii) is not guaranteed by
any of the Company's subsidiaries and is not secured by any lien on any property
or asset of the Company or any subsidiary of the Company, and (iii) has no
scheduled maturity of principal earlier than a date at least one year after the
scheduled maturity of the 2004 Notes and the 2005 Notes; (c) debt of up to $35.0
million under one or more credit agreements, under other existing debt
facilities, or to a seller, vendor or bank or other financial institution that
has financed or refinanced the purchase or lease of property, materials or a
business, not to exceed $17.5 million until the Company's number of basic
subscribers exceeds 200,000; (d) any debt of the Company (other than debt
described in clause (a), (b), or (c) above) in an amount outstanding not
exceeding, at the time of incurrence, the product of the Company's number of
basic subscribers in excess of 200,000 multiplied by (1) $375, if such debt is
incurred prior to January 1, 1998, (2) $325, if such debt is incurred thereafter
and prior to January 1, 1999, and (3) $275, if such debt is incurred thereafter,
if the net proceeds of such debt are invested exclusively in the transmission of
video, voice and data and related businesses and services conducted by the
Company and its subsidiaries; and (e) replacements, renewals, refundings or
extensions of any debt referred to in clauses (a) - (d) above, subject to
certain restrictions. As a result of such limitations, the Company's additional
borrowing capacity approximated $8.2 million at December 31, 1996.

to require ATI to repurchase all of such holder's 2004 Notes at 101% of the
accreted value (as defined) thereof, or, in the case of any such repurchase on
or after June 15, 1999, 101% of the principal amount at stated maturity thereof

in the event of a change of control of ATI, each holder of the 2005 Notes will
have the right to require ATI to repurchase all of such holder's 2005 Notes at
101% of the accreted value (as defined) thereof, or, in the case of any such
repurchase on or after August 15, 2000, 101% of the principal amount at stated
maturity thereof plus accrued and unpaid interest, if any, to the date of
repurchase. In addition, in the event of a sale by ATI prior to August 15, 1998
of at least $10 million of its capital stock to a strategic equity investor, up
to a maximum of 35% of the aggregate accreted value of outstanding 2005 Notes
may be redeemed at ATI's option within 30 days after such sale from the net cash
proceeds thereof at 113.50% of accreted value to the date of redemption;

  Fresno Facility
 
     During 1996, the Fresno Partnership maintained a revolving credit facility
(the "Fresno Facility") with a bank that provided for borrowings for the Fresno,
Visalia and Merced systems. As of December 31, 1996, no amounts were available
for borrowing under the Fresno Facility. The Fresno Facility was required to be
fully assigned to ATI by March 31, 1997. All amounts due to the bank under the
Fresno Facility were repaid by ATI in February 1997 with proceeds from the
Facility (as defined below). Outstanding borrowings under the Fresno Facility
bore interest at the banks' prime rate plus 2.25% (10.5% at December 31, 1996).
Interest expense relating to this facility during the year ended December 31,
1996 totaled $763,000. The facility was secured by the assets of the Fresno,
Visalia and Merced systems. The Fresno Facility also contained various financial
convenants and other restrictive covenants that, among other things, prohibited
the payment of dividends. As of September 30 and December 31, 1996, the Fresno
Partnership was not in compliance with certain of the restrictive covenants of
the Fresno Facility.

  Credit Facility
 
     On February 26, 1997, the Company entered into a $17,000,000 credit
facility (the "Facility") with Banque Indosuez, New York Branch (the "Bank").
The term of the Facility is up to twelve months. The loan must be repaid earlier
than the specified termination date and certain mandatory prepayments must be
made with proceeds from debt issuances or certain asset sales, including the
BellSouth Transaction. The Facility bears interest at a rate of 12.5%, which
rate shall increase by 0.50% per quarter. Borrowings under the Facility are
secured by a security interest in favor of the Bank in substantially all of the
assets of ATI and its subsidiaries. The Facility is further secured by a pledge
of the stock of substantially all of ATI's subsidiaries as well as a pledge of
the note due to the Company from its Fresno subsidiary under the Fresno
Facility.
 
     The Company paid the Bank a commitment fee of $340,000. At closing, the
Company paid an additional fee of $340,000 and reimbursed the Bank for its out
of pocket expenses incurred in conjunction with the making of the loan. During
the term of the Facility, the Company is required to pay to the Bank a
commitment commission on the unused loan balance at the annual rate of 0.50%.
 
     At closing, the Company also delivered 4,500 bond appreciation rights
("BARs") and an option to exercise 141,667 debt warrants or 141,667 equity
warrants. The debt warrants give the holder the right to increase the principal
amount of the loan by $6.00 per warrant, or the right to require the Company to
purchase the debt warrant for $6.00 per warrant. The debt warrants are
exercisable or puttable during a five-day period beginning on the earlier of one
year from the date of issuance, or notice that payment in full of the Facility
has occurred or will occur shortly. The equity warrants give the holder the
right to purchase up to 141,667 shares of the Company's Class A Common Stock for
a price of $3.281 per share. Pursuant to the option agreement relating to the
warrants, the equity warrants become exercisable only to the extent that the
holder elects not to exercise or put the debt warrants or, if the holder elects
to put the debt warrants to the Company, the Company fails to make payment
therefor within the time required. Amounts payable in connection with the BARs
are based upon the appreciation in price of $4.5 million face value of the
Company's 2004 Notes. The BARs are exercisable after the earlier of June 15,
1999 or the occurrence of an Event of Default under the 2004 Notes. The payment
due upon exercise of each BAR is equal to the market price of the 2004 Notes on
the closing date less $290. The net value of the BARs is payable to holders of
the BARs in cash. The Company has deposited $1.0 million in escrow to satisfy
certain interest obligations under the Facility.
 
  Retired Facilities
 
     Interest expense related to retired revolving credit facilities
approximated $982,000, $1.6 million and $27,000 during the years ended December
31, 1994, 1995 and 1996, respectively.
 
     The following table summarizes the book and fair values of the Company's
debt facilities at December 31, 1996 (dollars in thousands). Fair values for the
Company's 2004 Notes and 2005 Notes are based on quoted market prices. The fair
value of the Company's Fresno Facility and notes payable are estimated using
discounted cash flow analyses, using interest rates currently being offered for
loans with similar terms to borrowers of similar credit quality. The carrying
amount of accrued interest approximates its fair value.

8. COMMON STOCK, STOCK OPTIONS AND WARRANTS
 
  Stock Option Plan
 
     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" ("APB 25") and related
Interpretations in accounting for its employee stock options. Under APB 25,
because the exercise price of the Company's employee stock options is equal to
the market price of the underlying stock on the date of the grant, no
compensation expense is recognized. In October 1995, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 123
("SFAS No. 123"), "Accounting and Disclosure of Stock-Based Compensation," which
established an alternative method of expense recognition for stock-based
compensation awards to employees based on fair values. The Company elected not
to adopt SFAS No. 123 for expense recognition purposes.
 
     The Company maintains a stock option plan reserving 1,525,000 shares of
Class A Common Stock to be issued to officers and key employees under terms and
conditions to be set by the Company's Board of Directors. The options vest over
periods of up to three years and expire eight years from the date of issuance.
As of December 17, 1996, the Company repriced options for all exempt employees
at the fair market value on that date.
 
     Pro forma information regarding net income and earnings per share is
required by SFAS No. 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of SFAS No.
123. The fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted-average
assumptions for 1995 and 1996, respectively: risk-free interest rates of 6.31%
during each period; dividend yields of 0.0% during each period; volatility
factors of the expected market price of the Company's common stock of .61 and
 .64, and a weighted-average expected life of the option of four years.
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which 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
characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its employee
stock options.
 
     The weighted average fair value of options granted during 1995 and 1996 was
$7.43 and $3.91, respectively. For purposes of pro forma disclosures, the
estimated fair value of the options is amortized to expense over the options'
vesting period. The Company's pro forma net loss and pro forma net loss per
share applicable to Class A Common Stock as if the Company had used the fair
value accounting provisions of

  Warrants
 
     In conjunction with the 1995 Units Offering described in Note 7, ATI issued
201,700 warrants (the "1995 Warrants") to purchase an aggregate of 943,956
shares of ATI's Common Stock at an exercise price of $12.65 per share, subject
to adjustment under certain circumstances. Warrant holders may exercise the 1995
Warrants at any time on or after August 10, 1996 and on or prior to August 10,
2000. The 1995 Warrants will terminate and become void at the close of business
on August 10, 2000. Approximately $5.5 million of the proceeds from the 1995
Units Offering was allocated to the 1995 Warrants. As of December 31, 1996, no
1995 Warrants had been exercised.
 
     In conjunction with the 1994 Units Offering described in Note 7, ATI issued
915,000 warrants (the "1994 Warrants") to purchase an equal number of shares of
ATI's Common Stock. The 1994 Warrants have an exercise price of $12.68 per

Supplemental Indenture. The 1994 Warrants, as amended, were valued at
approximately $4.6 million. As of December 31, 1996, 1994 Warrants for the
purchase of 100 shares had been exercised.
 
     During the year ended December 31, 1996, additional warrants for the

9. SERIES B CONVERTIBLE PREFERRED STOCK
 
     During August and October 1996, the Company completed private placements of
a total of 250,000 shares of Series B Convertible Preferred Stock, resulting in
net proceeds to the Company of $23.8 million. The shares of Series B Convertible
Preferred Stock have a preferential, cumulative 5% dividend and are non-voting.
Each share of Series B Preferred Stock is convertible, at the option of the
holder, into that number of shares of Common Stock that is determined by
dividing (a) the sum of (i) the original issuance price for each such share of
Series B Preferred Stock plus (ii) the amount of all accrued but unpaid
dividends on each share of Series B Preferred Stock so converted, by (b) the
Conversion Price (as defined herein) in effect at the time of conversion. The
"Conversion Price" at any given time is equal to 80% of the prevailing market
price of the Class A Common Stock, provided that the Conversion Price cannot
exceed $12.50 or be less than $2.00. Accordingly, the Company recognized the
discount on the conversion as a dividend in the amount of $6,250,000.
 
     During 1996, 140,000 shares of Series B Convertible Preferred Stock were
converted into a total of 2,273,785 shares of the Company's Class A Common Stock
at conversion prices ranging from $4.33 to $7.87. Aggregate dividends paid or
payable to holders of the Series B Convertible Preferred Stock totaled
approximately $201,000 and are reflected in the accompanying statements of
operations as interest expense. As of December 31, 1996, 110,000 shares of
Series B Convertible Preferred Stock were outstanding.
 
10. LEASES
 
  Channel Lease Commitments
 
     The Company has entered into various agreements to lease FCC channel
authorizations to provide wireless cable services. Certain of these lease
agreements provide buy-out options to the Company based upon the number of
subscribers at the time of such buy-out. The leases typically provide for
five-year minimum terms and renewals thereafter at the option of the Company.
The Company's obligations under certain of the leases are subject to receipt by
the lessor of all necessary FCC approvals to begin providing service. Channel
lease expense during 1994, 1995 and 1996 approximated $951,000, $1.9 million and
$2.6 million, respectively.
 
     As of December 31, 1996, aggregate minimum annual channel lease payments
are summarized as follows (in thousands):

leases were nominal. The majority of such licenses were reassigned to the
Company during 1996.
 
  Operating Leases
 
     The Company leases various office, warehouse and transmission tower space
and certain office equipment, furniture and vehicles. Rent expense during 1994,
1995 and 1996 was approximately $1.2 million, $2.4 million and $2.7 million,

  Capital Leases
 
     The Company leases certain vehicles and office equipment under
noncancelable capital leases. Equipment capitalized under such leases as of
December 31, 1995 and 1996 was approximately $3.1 million and $2.2 million,
respectively. Future minimum payments for capital leases as of December 31, 1996
are approximately $1,051,000, $896,000, $225,000, $15,000 and $1,000 for the
years ending December 31, 1997 through 2001, respectively, including interest of
approximately $251,000.
 
11. COMMITMENTS AND CONTINGENCIES
 
  Seattle Agreement
 
     Pursuant to a consulting agreement, the Company issued 10% of the Common
Stock of American Telecasting of Seattle, Inc., to a third party, and is
required to issue up to an additional 5% in the event that a certain subscriber
level is achieved in the Seattle system once it becomes operational.
 
  Programming Agreements
 
     The Company has entered into a series of noncancelable agreements to
purchase entertainment programming for rebroadcast which expire through 2005.
The agreements generally require monthly payments based upon the number of
subscribers to the Company's systems, subject to certain minimums. Such expenses
totaled approximately $5.9 million, $14.4 million and $19.3 million in 1994,
1995 and 1996, respectively.
 
  Litigation
 
     In February 1994, a complaint was filed by Fresno Telsat, Inc. ("Fresno
Telsat") in the Superior Court of the State of California for the County of
Monterey against a director and officer of the Company, the Company, and other
named and unnamed defendants. The complaint seeks compensatory damages (in an
unspecified amount but estimated by the plaintiff to be no less than $5 million)
and exemplary damages against all defendants, costs, and other relief. The
complaint alleges, among other claims, that all defendants, including the
Company, participated in a conspiracy to misappropriate corporate opportunities
belonging to Fresno Telsat. Although the ultimate outcome of this matter cannot
be predicted, management believes, based on its review of this claim and
discussion with legal counsel, that the resolution of this matter will not have
a material impact on the Company's financial position or future results of
operations.

     On January 12, 1996, Videotron (Bay Area) Inc. filed a complaint against
ATI in the Circuit Court of the Thirteenth Judicial Circuit in and for
Hillsborough County, Florida. The Complaint alleges that ATI has caused certain
entities from which ATI leases channels and airtime for its Bradenton and
Lakeland, Florida wireless cable markets (the "ATI Lessors") to actively oppose
Videotron's FCC applications to increase broadcast power in Videotron's Tampa,
Florida wireless cable system (the "Tampa market") in violation of a
Non-Interference Agreement between Videotron and ATI (the "Non-Interference
Agreement"). The Complaint seeks injunctive relief directing ATI to perform all
acts, services and undertakings required under the Non-Interference Agreement,
including but not limited to using reasonable best efforts to cause the ATI
Lessors not to object to Videotron's attempt to increase broadcast power in the
Tampa market and to enter into certain non-interference agreements with respect
thereto. In the alternative, the Complaint seeks damages for breach of the
Non-Interference Agreement (in an unspecified amount but exceeding $15,000).
Recently, in responding to written interrogatories, Videotron estimated its
damages to be approximately $113.5 million. Although the ultimate outcome of
this litigation cannot be predicted at this time, management of ATI believes,
based upon its review of the Complaint and after consultation with counsel, that
resolution of this matter will not have a material adverse impact on the
Company's financial position or future results of operations.
 
     In addition, the Company is occasionally a party to legal actions arising
in the ordinary course of its business, the ultimate resolution of which cannot
be ascertained at this time. However, in the opinion of management, resolution
of such matters will not have a material adverse effect on the Company.
 
12. INCOME TAXES
 
     As of December 31, 1996, the Company had net operating loss carryforwards
("NOLs") for Federal income tax purposes of approximately $156.6 million. The
NOLs expire in years 2003 through 2011. The use of the NOLs is subject to
statutory and regulatory limitations regarding changes in ownership. SFAS No.
109 requires that the tax benefit of NOLs for financial reporting purposes be
recorded as an asset. To the extent that management assesses the realization of
deferred tax assets to be less than "more likely than not," a valuation reserve
is established.
 
     The temporary differences which give rise to deferred tax assets and
liabilities as of December 31, 1995 and 1996, are as follows (in thousands):

13. BENEFIT PLANS
 
     The Company sponsors a defined contribution profit sharing plan, the
"American Telecasting, Inc. 401(K) Retirement Plan" (the "Plan"). Substantially
all of the Company's employees are eligible to participate in the Plan, which
commenced existence on September 1, 1994. Company contributions to the Plan are
based on a percentage of employee's contributions, subject to certain maximum
limits. The cost of the Plan for the years ended December 31, 1994, 1995 and
1996 approximated $52,000, $249,000 and $122,000, respectively.
 
     The Company also sponsors an employee stock ownership plan, the "American
Telecasting, Inc. Associate Stock Purchase Plan" (the "Stock Purchase Plan").
Generally, all full-time employees who have been employed by the Company for at
least one year are eligible to participate in the Stock Purchase Plan. The
purchase price of each share of the Company's Class A Common Stock purchased by
Stock Purchase Plan participants is 90% of the closing price of the Class A
Common Stock on the last day of each calendar quarter. The shares are purchased
in the open market and the Company pays ten percent of the purchase price and
all administrative costs. An aggregate of 250,000 shares of the Company's Class
A Common Stock may be sold pursuant to the Stock Purchase Plan. As of December
31, 1996, 245,764 additional shares may be sold pursuant to the Stock Purchase
Plan. Employer contributions and administrative costs paid by the Company
related to the Stock Purchase Plan aggregated $16,000 and $22,000 during the

                 CREDIT AGREEMENT, dated as of February 26, 1997, among
American Telecasting, Inc., a Delaware corporation (the "Borrower" or "ATel"),
the lending institutions listed in Annex I (each a "Bank" and, collectively,
the "Banks") and the New York branch of Banque Indosuez ("Indosuez") as the
agent and collateral agent for the Banks (in such capacity, the "Agent").
Unless otherwise defined herein, all capitalized terms used herein and defined
in Section 8 are used herein as so defined.

                             W I T N E S S E T H :

                 WHEREAS, ATel desires to enter into the Loan Facility which,
among other things, provides for the making of Loans to ATel pursuant to the
terms and conditions of this Credit Agreement; and

                 WHEREAS, the Banks are willing to make available the Loan
Facility provided for in this Credit Agreement.

                 NOW, THEREFORE, IT IS AGREED:

                 SECTION 1.  Amount and Terms of Credit.

                 1.01.  Commitments.  Subject to and upon the terms and
conditions herein set forth, each Bank severally agrees at any time and from
time to time on and after the Effective Date and prior to the Loan Commitment
Termination Date, to make a Loan or Loans to ATel, which Loans shall be drawn
under the Loan Facility, as set forth below.  Such Loans are herein referred to
as the "Loans."

                 1.02.  Minimum Amount of Each Borrowing.  The minimum
aggregate principal amount of a Borrowing of Loans shall be $500,000 and, if
greater, shall be in integral multiples of $100,000.

                 1.03.  Notice of Borrowings.  Whenever ATel desires that the
Banks make Loans under the Loan Facility it shall give the Agent at the Agent's
Office prior to 10:00 A.M. (New York time) at least one Business Day's written
notice (or telephonic notice promptly confirmed in writing) of each such
Borrowing.  Each such notice, which shall be substantially in the form of
Exhibit E hereto (each a "Notice of Borrowing"), shall be irrevocable, shall be
deemed a representation by ATel that all conditions precedent to such Borrowing
have been satisfied and shall specify (i) the aggregate principal amount in
U.S.  dollars of the Loans to be made pursuant to such Borrowing and
<PAGE>   7
                                     - 2 -

(ii) the date of Borrowing (which shall be a Business Day).  The Agent shall as
promptly as practicable give each Bank written notice (or telephonic notice
promptly confirmed in writing) of each proposed Borrowing, of such Bank's
proportionate share thereof and of the other matters covered by the Notice of
Borrowing.

                 1.04.  Disbursement of Funds.  (a)  No later than 1:00 P.M.
(New York time) on the date specified in each Notice of Borrowing, each Bank
will make available to the Agent in New York its pro rata portion of each
Borrowing requested to be made on such date in the manner provided below.

                 (b)  Each Bank shall make available all amounts it is to fund
under any Borrowing on or after the Effective Date in immediately available
funds to the Agent to the account specified therefor by the Agent or if no
account is so specified at the Agent's Office and the Agent will make such
funds available to ATel by depositing to the account specified therefor by ATel
or if no account is so specified to its account at the Agent's Office the
aggregate of the amounts so made available in the type of funds received.
Unless the Agent shall have been notified by any Bank prior to the date of any
such Borrowing that such Bank does not intend to make available to the Agent
its portion of the Borrowing or Borrowings to be made on such date, the Agent
may assume that such Bank has made such amount available to the Agent on such
date of Borrowing, and the Agent, in reliance upon such assumption, may (in its
sole discretion and without any obligation to do so) make available to ATel a
corresponding amount.  If such corresponding amount is not in fact made
available to the Agent by such Bank and the Agent has made available same to
ATel, the Agent shall be entitled to recover such corresponding amount from
such Bank.  If such Bank does not pay such corresponding amount forthwith upon
the Agent's demand therefor, the Agent shall promptly notify ATel, and ATel
shall immediately pay such corresponding amount to the Agent.  The Agent shall
also be entitled to recover from such Bank or ATel, as the case may be,
interest on such corresponding amount in respect of each day from the date such
corresponding amount was made available by the Agent to ATel to the date such
corresponding amount is recovered by the Agent, at a rate per annum equal to
(x) if paid by such Bank, the Federal Funds Rate or (y) if paid by ATel, the
then applicable rate of interest, calculated in accordance with Section 1.07,
for the respective Loans.  The Agent shall also be entitled to recover from any
Bank an amount equal to any other losses incurred by the Agent  as a result of
the failure of such Bank to provide such amount as provided in this Credit
Agreement.

                                     - 3 -

                 (c)  Nothing herein shall be deemed to relieve any Bank from
its obligation to fulfill its commitment hereunder or to prejudice any rights
which ATel may have against any Bank as a result of any default by such Bank
hereunder.

                 1.05.  Notes.  (a)  ATel's obligation to pay the principal of
and interest on all the Loans made to it by each Bank shall be evidenced by a
promissory note (each, a "Note" and, collectively, the "Notes") duly executed
and delivered by ATel substantially in the form of Exhibit A hereto, with
blanks appropriately completed in conformity herewith.

                 (b)  The Note of ATel issued to each Bank shall (i) be
executed by ATel, (ii) be payable to the order of such Bank and be dated the
Effective Date, (iii) be in a stated principal amount equal to the Loan
Commitment of such Bank and be payable in the aggregate principal amount of the
Loans evidenced thereby, (iv) mature, with respect to each Loan evidenced
thereby, on the Final Maturity Date, (v) be subject to mandatory prepayment as
provided in Section 2.02, (vi) bear interest as provided in Section 1.07 and
(vii) be entitled to the benefits of this Credit Agreement and the other
applicable Credit Documents.

                 (c)  Each Bank will note on its internal records the amount of
each Loan made by it and each payment in respect thereof and will, prior to any
transfer of any of its Notes, endorse on the reverse side thereof the
outstanding principal amount of Loans evidenced thereby.  Failure to make any
such notation shall not affect ATel's obligations hereunder or under the other
applicable Credit Documents in respect of such Loans.

                 1.06.  Pro Rata Borrowings.  All Borrowings under this
Agreement shall be loaned by the Banks pro rata on the basis of their Loan
Commitments.  No Bank shall be responsible for any default by any other Bank in
its obligation to make Loans hereunder and each Bank shall be obligated to make
the Loans provided to be made by it hereunder, regardless of the failure of any
other Bank to fulfill its commitments hereunder.

                 1.07.  Interest.  (a)  The unpaid principal amount of each
Loan shall bear interest from the date of the Borrowing thereof until maturity
(whether by acceleration or otherwise) at a rate per annum of 12.50%, which
rate shall increase by  0.50% on each February 16, May 16, August 16 and
November 16, commencing May 16, 1997.

                                     - 4 -

                 (b)  Following the occurrence and during the continuance of
any Event of Default under Section 7.01 hereof or with respect to any breach of
the covenants set forth in Section 5 or Section 6 hereof, each Loan (including
overdue principal and, to the extent permitted by law, overdue interest in
respect of any Loan) shall bear interest at the rate of interest applicable
thereto plus 2%.

                 (c)  Interest shall accrue from and including the date of any
Borrowing to but excluding the date of any repayment thereof and shall be
payable quarterly in arrears on each February 15, May 15, August 15 and
November 15 beginning on May 15, 1997.

                 1.08.  Capital Requirements.  If any Bank shall have
determined that the adoption or effectiveness after the Effective Date of any
applicable law, rule or regulation regarding capital adequacy, or any change
therein, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by such Bank or such
Bank's parent with any request or directive regarding capital adequacy (whether
or not having the force of law) of any such authority, central bank or
comparable agency (including in each case any such change proposed or published
prior to the date hereof), has or would have the effect of reducing the rate of
return on such Bank's or such Bank's parent's capital or assets as a
consequence of such Bank's obligations hereunder to a level below that which
such Bank or such Bank's parent could have achieved but for such adoption,
effectiveness or change or as a consequence of an increase in the amount of
capital required to be maintained by such Bank (including in each case, without
limitation, with respect to any Bank's Commitment or any Loan), then from time
to time, within 15 days after demand by such Bank (with a copy to the Agent),
ATel shall pay to such Bank such additional amount or amounts as will
compensate such Bank or such Bank's parent, as the case may be, for such
reduction.  Each Bank, upon determining in good faith that any additional
amounts will be payable pursuant to this Section 1.08, will give prompt written
notice thereof to ATel, which notice shall set forth in reasonable detail the
basis of the calculation of such additional amounts, although any delay in
giving any notice shall not release or  diminish any of ATel's obligations to
pay additional amounts pursuant to this Section 1.08.

                 1.09.  Total Loan Commitments.  The aggregate amount of the
Total Loan Commitments is $17,000,000.  Anything con-
<PAGE>   10
                                     - 5 -

tained in this Credit Agreement to the contrary notwithstanding, in no event
shall the aggregate principal amount of all Loans of any Bank at any time
exceed such Bank's portion of the Total Loan Commitments.

                 1.10.  Commitment Commission.  ATel agrees to pay the Agent a
commitment commission ("Commitment Commission") for the account of each Bank
for the period from and including the Effective Date to but not including the
date the Total Loan Commitments have been terminated, computed at a rate equal
to .50% per annum on the daily average Unutilized Commitment of such Bank.
Accrued Commitment Commission shall be due and payable in arrears on the
fifteenth day of each February, May, August and November commencing on the
fifteenth day of May 1997 and on the Loan Commitment Termination Date.

                 SECTION 2.  Payments.

                 2.01.  Voluntary Prepayments.  ATel shall have the right to
prepay Loans in whole or in part from time to time, without premium or penalty,
on the following terms and conditions:  (i) ATel shall give the Agent at the
Agent's Office written notice (or telephonic notice promptly confirmed in
writing) of its intent to prepay the Loans and the amount of such prepayment,
which notice shall be given by ATel at least one Business Day prior to the date
of such prepayment and which notice shall promptly be transmitted by the Agent
to each of the Banks; and (ii) each partial prepayment shall be in an aggregate
principal amount of at least $100,000 and integral multiples of $100,000 in
excess of that amount.  All payments made under this Section 2.01 shall reduce
the Total Loan Commitments on a pro rata basis.

                 2.02.  Mandatory Prepayments.

                 (A)  Requirements:

                 (a)  ATel shall prepay the outstanding principal amount of the
         Loans on any date on which the aggregate outstanding principal amount
         of such Loans (after giving effect to any other repayments or
         prepayments on such day)  exceeds the Total Loan Commitments in the
         amount of such excess.

                 (b)  On the day following the receipt thereof by ATel, an
         amount equal to 100% of the proceeds received by ATel in Cash or Cash
         Equivalents (net of underwriting discounts and commissions and other
         costs and expenses di-
<PAGE>   11
                                     - 6 -

         rectly associated therewith) of the sale after the Effective Date of
         equity securities shall be applied as provided in Section 2.02(B).

                 (c)  On the day following receipt thereof by ATel, an amount
         equal to 100% of any insurance proceeds received (net of direct
         expenses of recovery, including reasonable and customary legal fees),
         less any portion of such proceeds not in excess of $100,000 that is
         promptly applied to repair or replace the damaged property in respect
         of which such proceeds were received (provided that, if the damaged
         property constituted Collateral, any such replacement property shall
         be made subject to the Lien of the Security Documents), shall be
         applied as provided in Section 2.02(B).

                 (d)  On the day following the receipt thereof by ATel, an
         amount equal to 100% of any tax refund made to ATel (net of direct
         expenses of recovery, including reasonable and customary legal fees)
         shall be applied as provided in Section 2.02(B).

                 (B)  Application:  With respect to each prepayment of Loans
required by Section 2.02(A), ATel shall give the Agent two Business Days'
notice.  All prepayments shall include payment of accrued interest on the
principal amount so prepaid and shall be applied to the payment of interest
before application to principal.  All payments required under this Section 2.02
shall reduce the Total Loan Commitments on a pro rata basis.

                 2.03.  Method and Place of Payment.  (a)  Except as otherwise
specifically provided herein, all payments under this Credit Agreement shall be
made to the Agent, for the ratable account of the Banks entitled thereto, not
later than 1:00 P.M.  (New York time) on the date when due and shall be made in
immediately available funds in lawful money of the United States of America to
the account specified therefor by the Agent or if no account has been so
specified at the Agent's Office, it being understood that written notice by
ATel to the Agent to make a payment from the funds in ATel's account at the
Agent's Office shall constitute the making of such payment to the extent of
such funds held in such account.  The Agent will thereafter cause to be
distributed on the same day (if payment is actually received by the Agent in
New York prior to 1:00 P.M. (New York time) on such day) funds relating to the
payment of principal or interest or fees ratably to the Banks entitled to
receive any such payment in accordance with the terms of this Credit Agreement.
If and to the extent that any such distribution
<PAGE>   12
                                     - 7 -

shall not be so made by the Agent in full on the same day (if payment is
actually received by the Agent prior to 1:00 P.M. (New York time) on such day),
the Agent shall pay to each Bank its ratable amount thereof and each such Bank
shall be entitled to receive from the Agent, upon demand, interest on such
amount at the Federal Funds Rate for each day from the date such amount is paid
to the Agent until the date the Agent pays such amount to such Bank.

                 (b)  Any payments under this Credit Agreement which are made
by ATel later than 1:00 P.M. (New York time) shall be deemed to have been made
on the next succeeding Business Day.  Whenever any payment to be made hereunder
shall be stated to be due on a day which is not a Business Day, the due date
thereof shall be extended to the next succeeding Business Day and, with respect
to payments of principal, interest shall be payable during such extension at
the applicable rate in effect immediately prior to such extension.

                 2.04.  Net Payments.  (a)  All payments by ATel to or for the
account of any Bank or the Agent under any Credit Document shall be made
without set-off or counterclaim and in such amounts as may be necessary in
order that all such payments (after deduction or withholding for or on account
of any present or future taxes, levies, imposts, duties or similar charges
imposed by any government or any political subdivision or taxing authority
thereof on the payment to or for the account of any Bank or the Agent under any
Credit Document, other than any tax on or measured by the income of a Bank
(including any franchise or similar tax so measured) pursuant to the income tax
laws of the United States or of the jurisdiction in which it is incorporated or
organized or the jurisdiction where such Bank's lending office is located
(collectively,  such non-excluded taxes hereinafter referred to as "Taxes"))
shall not be less than the amounts otherwise specified to be paid under any
Credit Document.  A Bank to which additional amounts are payable will provide
ATel with a certificate setting forth in sufficient detail the calculation and
amount of such additional amounts payable to such Bank under this Section
2.04(a).  With respect to each deduction or withholding for or on account of
any Taxes, ATel shall promptly furnish to each Bank such certificates, receipts
and other documents as may be required (in the reasonable judgment of such
Bank) to establish any tax credit to which such Bank may be entitled.

                 (b)      Without prejudice to the provisions of clause (a) of
this Section 2.04, if any Bank, or the Agent on its behalf, is required by law
to make any payment on account
<PAGE>   13
                                     - 8 -

of Taxes on or in relation to any sum received or receivable under any Credit
Document by such Bank, or the Agent on its behalf, ATel will promptly indemnify
such person against such Tax payment, together with any interest and penalties
payable or incurred in connection therewith, computed in a manner consistent
with clause (a) of this Section 2.04 upon receipt of a certificate by such Bank
providing in sufficient detail the calculation and amount of such payments.

                 (c)      Each Bank organized under the laws of a jurisdiction
outside the United States, on or contemporaneously with the date of its
execution and delivery of this Agreement in the case of each Bank listed on the
signature pages hereof and on or prior to the date on which it becomes a Bank
in the case of each other Bank, and from time to time thereafter if requested
in writing by ATel (but only so long as such Bank remains lawfully able to do
so), shall provide ATel with Internal Revenue Service form 1001 or 4224, as
appropriate, or any successor form prescribed by the Internal Revenue Service,
certifying that such Bank is entitled to benefits under an income tax treaty to
which the United States is a party which reduces the rate of the withholding
tax on payments of interest or certifying that the income receivable pursuant
to this Agreement is effectively connected with the conduct of a trade or
business in the United States.  If the form provided by a Bank at the time such
Bank first becomes a party to this Agreement indicates a United States interest
withholding tax rate in excess of zero, withholding tax at such rate shall be
considered excluded from "Taxes" as defined in Section 2.04(a).

                 (d)      For any period with respect to which a Bank has
failed to provide ATel with the appropriate form pursuant to  Section 2.04(c)
(unless such failure is due to a change in treaty, law or regulation occurring
subsequent to the date on which a form originally was required to be provided),
such Bank shall not be entitled to indemnification under Section 2.04(a) or
2.04(b) with respect to Taxes imposed by the United States; provided, however,
that should a Bank which is otherwise exempt from or subject to a reduced rate
of withholding tax become subject to Taxes because of its failure to deliver a
form required hereunder, ATel shall take such steps as such Bank shall
reasonably request to assist such Bank to recover such Taxes.

                 (e)      If ATel is required to pay additional amounts to or
for the account of any Bank pursuant to this Section 2.04, then such Bank will
change the jurisdiction of its lending office so as to eliminate or reduce any
such additional payment
<PAGE>   14
                                     - 9 -

which may thereafter accrue if such change is not, in the sole judgment of such
Bank, disadvantageous to such Bank.

         that it is being made as of any other specific date in which case on
         and as of such other date.
<PAGE>   19
                                     - 14 -

                 (C)  Adverse Change, etc.  Since December 31, 1996, nothing

                 (D)  Margin Rules.  On the date of each Borrowing of Loans,
         neither the making of any Loan nor the use of the proceeds thereof
         will violate the provisions of Regulation G, T, U or X of the Board of
         Governors of the Federal Reserve System.

                 The acceptance of the proceeds of each Borrowing of Loans
shall constitute a representation and warranty by ATel to each of the Banks
that all of the applicable conditions specified in Section 3.02 (in each case
disregarding any reference therein that such condition be deemed satisfactory
by the Agent and/or the Required Banks) have been satisfied or waived.

                 All of the certificates, legal opinions and other documents
and papers requested by the Agent, unless otherwise specified, shall be
delivered to the Agent at the Agent's Office (or such other location as may be
specified by the Agent) for the account of each of the Banks and in sufficient
counterparts for each of the Banks and shall be reasonably satisfactory in form
and substance to the Agent.

                 SECTION 4.  Representations, Warranties and Agreements.  In
order to induce the Banks to enter into this Agreement and to make the Loans
provided for herein, ATel makes the following representations and warranties
to, and agreements with, the Banks, all of which shall survive the execution
and delivery of this Agreement and the making of the Loans (with the execution
and delivery of this Agreement and the making of each Loan thereafter being
deemed to constitute a representation and warranty that the matters specified
in this Section 4 are true and correct in all material respects as of the date
of  each such Loan unless such representation and warranty expressly indicates
that it is being made as of any specific date):

                 4.01.  Corporate Status.  Each Credit Party (i) is a duly
organized and validly existing corporation in good standing under the laws of
its respective jurisdiction of incorporation; (ii) has the corporate or other

                                     - 15 -

erate its property and assets and to transact the business in which it is
engaged and presently proposes to engage, except for those governmental
licenses, authorizations, consents or approvals the failure of which to be so
obtained would not have a Materially Adverse Effect; and (iii) is duly
qualified and is authorized to do business and is in good standing in all
jurisdictions where it is required to be so qualified and where the failure to
be so qualified would have a Materially Adverse Effect.

                 4.02.  Corporate Power and Authority; Business.  Each Credit
Party has the corporate power and authority to execute, deliver and carry out
the terms and provisions of the Credit Documents to which it is a party and has
taken all necessary corporate action to authorize the execution, delivery and
performance of the Credit Documents to which it is a party.  Each Credit Party
has duly executed and delivered each Credit Document to which it is a party and
each such Credit Document constitutes the legal, valid and binding obligation
of such entity enforceable in accordance with its terms except as such
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws relating to or limiting creditors' rights generally
or by equitable principles relating to enforceability.

                 4.03.  No Violation.  Neither the execution, delivery and
performance by each Credit Party of the Credit Documents to which it is a party
nor compliance with the terms and provisions thereof, nor the consummation of
the transactions contemplated therein (i) will contravene any applicable
provision of any law, statute, rule, regulation, order, writ, injunction or
decree of any court or governmental instrumentality, (ii) will conflict or be
inconsistent with or result in any breach of any of the terms, covenants,
conditions or provisions of, or constitute a default under, or (other than
pursuant to the  Security Documents) result in the creation or imposition of
(or the obligation to create or impose) any Lien upon any of the property or
assets of such Credit Party pursuant to the terms of any indenture, mortgage,
deed of trust, material agreement or other material instrument to which such
Credit Party is a party or by which it or any of its property or assets is
bound or to which it may be subject or (iii) will violate any provision of the
charter or by-laws of such Credit Party, except where such contravention,
conflict, inconsistency, breach, default, creation, imposition, obligation or
violation would not have a Materially Adverse Effect.  ATel and its
Subsidiaries have all easements, licenses and rights of way necessary to
conduct
<PAGE>   21
                                     - 16 -

their business except where failure to have the same will not have a Materially
Adverse Effect.

                 4.04.  Litigation.  There are no actions, judgments, suits or
proceedings pending or, to ATel's knowledge, threatened with respect to ATel or
its Subsidiaries that are likely, individually or in the aggregate, to have a
Materially Adverse Effect.

                 4.05.  Use of Proceeds.  (a)  The proceeds of all Loans to be
made to ATel hereunder shall be utilized to repay outstanding Indebtedness of
ATel or its Subsidiaries and for general corporate purposes, including to
finance the working capital requirements of ATel or its Subsidiaries, or for
any of the capital expenditures and acquisitions of channel rights set forth on
Annex 4.05 hereto.  $1 million of the initial Borrowing hereunder shall be
deposited with the Escrow Agent under the terms of the Escrow Agreement.

                 (b)  Neither the making of any Loan hereunder, nor the use of
the proceeds thereof, will violate or be inconsistent with the provisions of
Regulation G, T, U or X of the Board of Governors of the Federal Reserve
System.

                 4.06.  Governmental Approvals, etc.  No order, consent,
approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, any third party or any governmental or
public body or authority, or by any subdivision thereof, including but not
limited to any radio, television or other license, permit, certificate or
approval granted or issued by the FCC or any other Governmental Authority
(including without limitation any MDS, MMDS, ITFS, business radio, earth
station operational fixed service, local MDS, or experimental licenses or
permits issued by the FCC) (other than those orders, consents, approvals,
licenses,  authorizations or validations which have previously been obtained or
made and except for filings to perfect security interests granted pursuant to
the Security Documents, all of which will be accomplished on or prior to the
Closing Date), is required to authorize or is required in connection with (i)
the execution, delivery and performance of any Credit Document or the
transactions contemplated therein or (ii) the legality, validity, binding
effect or enforceability of any Credit Document; provided, however, to the
extent the performance of any Credit Document or the transactions contemplated
therein involves a transfer of control
<PAGE>   22
                                     - 17 -

or assignment of any license, permit, certificate or other authorization issued
by the FCC, then FCC approval may be required prior to such transfer of control
or assignment.  At the time of the making of the Loans, there does not exist
any judgment, order, injunction or other restraint issued or filed with respect
to the making of loans or the performance by the Credit Parties of their
respective obligations under the Credit Documents.

                 4.07.  Investment Company Act.  ATel is not, nor will it be
after giving effect to the transactions contemplated hereby, an "investment
company" or a company "controlled" by an "investment company," within the
meaning of the Investment Company Act of 1940, as amended.

                 4.08.  Public Utility Holding Company Act.  ATel is not, nor
will be after giving effect to the transactions contemplated hereby, a "holding
company," or a "subsidiary company" of a "holding company," or an "affiliate"
of a "holding company" or of a "subsidiary company" of a "holding company,"
within the meaning of the Public Utility Holding Company Act of 1935, as
amended.

                 4.09.  True and Complete Disclosure.  All factual information
(taken as a whole) heretofore or contemporaneously furnished by or on behalf of
ATel in writing to any Bank for purposes of or in connection with this Credit
Agreement or any transaction contemplated herein is, and all other such factual
information (taken as a whole) hereafter furnished by or on behalf of ATel in
writing to any Bank will be, true and accurate in all material respects on the
date as of which such information is dated or certified and not incomplete by
omitting to state any material fact necessary to make such information not
misleading at such time in light of the circumstances under which such
information was provided.  The projections and pro forma financial information
contained in such materials are based on good faith estimates and assumptions
believed by ATel  to be reasonable at the time made, it being recognized by the
Banks that such projections as to future events are not to be viewed as facts
and that actual results during the period or periods covered by any such
projections may differ materially from the projected results.  There is no fact
known to ATel which materially and adversely affects the business, operations,
property, assets, nature of assets, liabilities, condition (financial or
otherwise) or prospects of ATel and its Subsidiaries, taken as a whole, which
has not been disclosed herein or in such other documents, certificates and
written statements furnished to the Banks.

                 4.10.  Financial Condition; Financial Statements; Projections.
(a)  ATel and its Subsidiaries are not entering
<PAGE>   23
                                     - 18 -

into the arrangements contemplated hereby and by the other Credit Documents,
nor intends to make any transfer or incur any obligations hereunder or
thereunder, with actual intent to hinder, delay or defraud either present or
future creditors.  On and as of the Effective Date, on a pro forma basis after
giving effect to all Indebtedness incurred and Liens created, or to be created,
by ATel and its Subsidiaries in connection herewith, (w) ATel does not expect
that final judgments against ATel or its Subsidiaries in actions for money
damages with respect to pending or threatened litigation will be rendered at a
time when, or in an amount such that, ATel and its Subsidiaries, on a
consolidated basis, will be unable to satisfy any such judgments promptly in
accordance with their terms (taking into account the maximum reasonable amount
of such judgments in any such actions and the earliest reasonable time at which
such judgments might be rendered and the cash available to ATel or its
Subsidiaries, after taking into account all other anticipated uses of the cash
of ATel or its Subsidiaries (including the payments on or in respect of debts
(including its Contingent Obligations)); (x) ATel and its Subsidiaries will not
have incurred nor intends to, nor believes that they will, incur debts beyond
their ability to pay such debts as such debts mature (taking into account the
timing and amounts of cash to be received by ATel and its Subsidiaries from any
source, and of amounts to be payable on or in respect of debts of ATel and its
Subsidiaries and the amounts referred to in the preceding clause (w)); (y) ATel
and its Subsidiaries, on a consolidated basis, after taking into account all
other anticipated uses of the cash of ATel and its Subsidiaries, anticipates
being able to pay all amounts on or in respect of debts of ATel and its
Subsidiaries when such amounts are required to be paid; and (z) ATel and its
Subsidiaries, on a consolidated basis, will have sufficient capital with which
to conduct its present and  proposed business and the property of ATel and its
Subsidiaries does not constitute unreasonably small capital with which to
conduct its present or proposed business.  For purposes of this Section 4.10,
"debt" means any liability on a claim, and "claim" means a (i) right to payment
whether or not such a right is reduced to judgment, liquidated, unliquidated,
fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable,
secured or unsecured; or (ii) right to an equitable remedy for breach of
performance if such breach gives rise to a payment, whether or not such right
to an equitable remedy is reduced to judgment, fixed, contingent, matured,
unmatured, disputed, undisputed, secured or unsecured.  On the date of each
Borrowing (and after giving effect to all Borrowings as of such date), the
representations set forth in this Section
<PAGE>   24
                                     - 19 -

4.10(a) shall be true and correct with respect to ATel and its Subsidiaries on
such date.

                 (b)  ATel has heretofore delivered to the Banks the financial
statements set forth in Section 3.01(I).  All the financial statements referred
to in the preceding sentence were prepared in accordance with GAAP consistently
applied, except in the case of interim financial statements for normal year-end
adjustments and the absence of footnote disclosures.  Such financial statements
fairly present in all material respects the financial position of ATel for each
of the periods covered thereby.  Except as disclosed to the Banks prior to the
Effective Date, since December 31, 1996 no event or events have occurred that
could reasonably be expected to have a Materially Adverse Effect.

                 (c)  There have heretofore been delivered to the Banks pro
forma consolidated income projections for ATel, pro forma consolidated balance
sheet projections for ATel and pro forma consolidated cash flow projections for
ATel, all for the fiscal year ending December 31, 1997 (the "Projected
Financial Statements").  The Projected Financial Statements present a good
faith estimate of the consolidated financial information contained therein at
the date thereof.

                 (d)  As of the Effective Date, except as fully reflected or
reserved against in the financial statements and the notes thereto described in
Section 4.10(b), there were no liabilities or obligations with respect to ATel
or its Subsidiaries of any nature whatsoever (whether absolute, accrued,
contingent or otherwise and whether or not due) which, either individually or
in aggregate, would reasonably be expected to be material to ATel.  As of the
Effective Date, ATel does not  know of any basis for the assertion against ATel
or its Subsidiaries of any liability or obligation of any nature whatsoever
that is not fully reflected in the financial statements described in Section
4.10(b) or (c) which, either individually or in the aggregate, could reasonably
be expected to be material to ATel and its Subsidiaries, taken as a whole.

                 4.11.  Security Interests.  The Security Documents, once
executed and delivered, create, as security for the obligations purported to be
secured thereby, a valid and enforceable perfected first priority security
interest in and Lien in favor of the Collateral Agent for the benefit of the
Banks on all of the Collateral, superior to and prior to the rights of all
third persons other than Prior Liens relating to such Collateral and subject to
no other Liens except Liens which are
<PAGE>   25
                                     - 20 -

expressly permitted under the applicable Security Document, except to the
extent otherwise provided therein.  As of the Effective Date and thereafter,
each Credit Party has (or on and after the time it executes each Security
Document, will have) good and marketable title to all items of Collateral
covered by such Security Document free and clear of all Liens except any Prior
Lien relating to such Collateral or other Liens which are expressly permitted
under the applicable Security Document.  Other than as contemplated in Section
3.01(L), no filings or recordings are required in order to perfect the security
interests created under the Security Documents except for filings or recordings
required in connection with the Security Documents which shall have been made
prior to or contemporaneously with the execution and delivery thereof or have
been otherwise made.

                 4.12.  Tax Returns and Payments.  ATel has filed all material
tax returns required to be filed by it and has paid all material taxes and
assessments payable by it which have become due, other than those not yet
delinquent and except for those being diligently contested in good faith and by
appropriate proceedings.  ATel has provided adequate tax reserves in accordance
with GAAP.  ATel knows of no proposed tax assessment against it that could
reasonably be expected to have a Materially Adverse Effect.

                 4.13.  ERISA.  (A)  Each of ATel and the ERISA Affiliates is
in compliance in all material respects with all applicable provisions of ERISA
and the regulations and published interpretations thereunder with respect to
all employee benefit plans, Pension Plans and Multiemployer Plans currently
maintained by ATel or any of its ERISA Affiliates.

                 (B)  No Termination Event has occurred or is reasonably
expected to occur with respect to any Pension Plan which resulted or could
reasonably be expected to result in a material liability to ATel or any ERISA
Affiliate.

                 (C)  As of the Effective Date, neither ATel nor any ERISA
Affiliate maintains or contributes to any Title IV Plan or Multiemployer Plan.
Neither ATel nor any ERISA Affiliate has incurred or reasonably expects to
incur any material withdrawal liability under Section 4201 et seq. of ERISA to
any Multiemployer Plan or any employee benefit plan of the type described in
Sections 4063 and 4064 of ERISA or in Section 413(c) of the Code.
<PAGE>   26
                                     - 21 -

                 (D)  Neither ATel nor any ERISA Affiliate has incurred any
accumulated funding deficiency (whether or not waived) with respect to any
Pension Plan.

                 (E)  Neither ATel nor any ERISA Affiliate has or reasonably
expects to become subject to a Lien in favor of any Pension Plan under Section
302(f) or 307 of ERISA or Section 401(a)(29) or 412(n) of the Code.

                 As used in this Section 4.13, the term "accumulated funding
deficiency" has the meaning specified in Section 302 of ERISA and Section 412
of the Code, and the term "employee benefit plan" has the meaning specified in
Section 3(3) of ERISA.

                 4.14.  Patents, etc.  ATel and its Subsidiaries have obtained
all material patents, trademarks, service marks, trade names, copyrights,
licenses and other rights, free from burdensome restrictions, that are
necessary for the operation of their respective businesses as presently
conducted and as proposed to be conducted.

                 4.15.  Compliance with Laws, etc.  ATel (i) is in compliance
with all laws and regulations, including without limitation those relating to
pollution and environmental control, equal employment opportunity and employee
safety, in all jurisdictions in which it is presently doing business, including
all FCC rules and regulations, and rules and regulations of the U.S. Copyright
Office, and (ii) will comply and cause each of its Subsidiaries to comply with
all such laws and regulations which may be imposed in the future in
jurisdictions in which it or such Subsidiary may then be doing business, other
than those noncompliances in clauses (i) and (ii) above which would not have a
Materially Adverse Effect.

                 4.16.  Properties.  ATel and each of its Subsidiaries have
good and marketable title to and beneficial ownership of all their respective
material properties owned by them, including after the Effective Date all
property reflected in the most recent balance sheet referred to in Section
4.10(b) and except as sold or otherwise disposed of since the date of such
balance sheet in the ordinary course of business, free and clear of all Liens,
other than, with respect to property constituting Collateral, Prior Liens and
other liens expressly permitted under the applicable Security Document, and
with respect to property not constituting Collateral, Permitted Encumbrances.
ATel, and each Subsidiary thereof, holds all material licenses, certificates of
occupancy or operation and similar certificates and clearances of municipal and
other authorities necessary to own
<PAGE>   27
                                     - 22 -

and operate its properties in the manner and for the purposes currently
operated by such party.  ATel, and each of its Subsidiaries, has easements or
rights-of-way adequate for the operations and maintenance of its transmission
and distribution lines.  There are no actual, threatened or alleged defaults of
a material nature with respect to any leases of real property under which ATel,
or any of its Subsidiaries, is lessor or lessee.

                 4.17.  Securities.  (a)  The Common Stock of ATel is duly
authorized, issued and delivered and is fully paid, nonassessable and free of
preemptive rights.  Except as set forth on Annex 4.17(a), there are not, as of
the Effective Date, any existing options, warrants, calls, subscriptions,
convertible or exchangeable securities, rights, agreements, commitments or
arrangements for any person to acquire any capital stock of ATel or any other
securities convertible into, exchangeable for or evidencing the right to
subscribe for any such capital stock.

                 (b)  ATel has no Subsidiaries other than as set forth on Annex
4.17(b).  Except as set forth on Annex 4.17(a), there are not, as of the
Effective Date, any existing options, warrants, calls, subscriptions,
convertible or exchangeable securities, rights, agreements, commitments or
arrangements for any person to acquire any interest of any direct or indirect
Subsidiary of ATel or any other securities convertible into, exchangeable for
or evidencing the right to subscribe for any such interest.

                 4.18.  Collective Bargaining Agreements.  Neither ATel nor any
of its Subsidiaries has, as of the date hereof, any collective bargaining or
similar agreements between or  applicable to ATel and its Subsidiaries and any
union, labor organization or other bargaining agent in respect of the employees
of ATel or its Subsidiaries.

                 4.19.  Indebtedness Outstanding.  Set forth on Annex 4.19
hereto is a list and description of all Indebtedness of ATel and its
Subsidiaries that will be outstanding immediately prior to the Effective Date.
Annex 4.19 identifies which portions of such Indebtedness will be repaid with
the proceeds of the Loans.

Materially Adverse Effect,

<PAGE>   28
                                     - 23 -

         (collectively "Authorizations") which are required with respect to the
         operation of the business of ATel and its Subsidiaries, in each case
         taken as a whole, under any Environmental Law and each such
         Authorization is in full force and effect.

                 (B)  ATel and each of its Subsidiaries are in compliance with

         under CERCLA or RCRA or any comparable state law nor has ATel or any
         of its Subsidiaries received any  notification that any hazardous

                 (c)  Except as disclosed on Annex 4.21(b) hereto, as of the
Closing Date (1) each System Agreement listed under Annex 4.21(a) hereto is in
full force and effect and no other approval, application, filing, registration,

                 SECTION 5.  Affirmative Covenants.  ATel covenants and agrees

         examination has included a review of such terms of Sections 5, 6, 7
         and 8 of this Agreement which solely relate to accounting matters but
         without having conducted any special auditing procedures in connection
         therewith, (ii) stating whether, in connection with their audit
         examination, any condition or event which constitutes a Default or
         Event of Default has come to their attention, and if such a condition
         or event has come to their attention, specifying the nature and period
         of existence thereof; provided that such accountants shall not be

         Default or Event of Default that would not be disclosed in the course
         of their audit examination, and (iii) stating that based on their

         accounting matters  or, if a Default or Event of Default so existed,
         describing such Default or Event of Default.

document or conversation believed by it to be genuine and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of

accountants and other experts selected by the Agent.  The Agent shall be fully
justified in failing or refusing to take any action under this Credit Agreement
or any other Credit Document unless it shall first receive  such advice or
concurrence of the Required Banks as it deems appropriate or it shall first be
indemnified to its satisfaction by the Banks against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take

representations or warranties to it and that no act by the Agent hereinafter

shall be deemed to constitute any representation or warranty by the Agent to
any Bank.  Each Bank represents to the Agent that it has, independently and
without reliance upon the Agent or any other Bank, and based on such documents
and information as it has deemed appropriate, made its own appraisal of and
investigation into the business, assets, operations, property, financial and
other conditions, prospects and creditworthiness of ATel and its Subsidiaries
and made its own decision to make its Loans hereunder and enter into this
Credit Agreement and the other agreements contemplated hereby.  Each Bank also

any other Bank, and based on such documents and  information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Credit Agreement, and
to make such investigation as it deems necessary to inform itself as to the
business, assets, operations, property, financial and other conditions,
prospects and creditworthiness of ATel and its Subsidiaries.  Except for
notices, reports and other documents expressly required to be furnished to the
Banks by the Agent hereunder, the Agent shall not have any duty or
responsibility to provide any Bank with any credit or other information
concerning the business, operations, assets, property, financial and other

liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, reasonable expenses or disbursements of any kind whatsoever which

payment of the Obligations) be imposed on, incurred by or asserted against the
Agent in its capacity as such in any way relating to or arising out of this
Credit Agreement or any other Credit Document, or any documents contemplated by
or referred to herein or the transactions contemplated hereby or any action
taken or omitted to be taken by the Agent under or in connection with any of
the foregoing, but only to the extent that any of the foregoing is not paid by
ATel or any of its Subsidiaries; provided that no Bank shall be liable to the
Agent for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting solely from the Agent's gross negligence or willful misconduct.  If
any indemnity furnished to the Agent for any purpose shall, in the opinion of
the Agent, be insufficient or become impaired, the Agent may call for
additional indemnity and cease, or not commence, to do the acts indemnified
against until such additional indemnity is furnished.  The agreements in this
Section 9.07 shall survive the payment of all Obligations.

                 9.08.  The Agent in Its Individual Capacity.  The Agent and
its Affiliates may make loans to, accept deposits from and generally engage in
any kind of business with ATel,  its Subsidiaries and other Affiliates of ATel
as though the Agent were not the Agent hereunder.  With respect to the Loans
made by it and all Obligations owing to it, the Agent shall have the same
rights and powers under this Credit Agreement as any Bank and may exercise the
same as though it were not the Agent, and the terms "Bank" and "Banks" shall
include the Agent in its individual capacity.

                 9.09.  Successor Agent.  Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, the term "Agent" shall
include such successor agent effective upon its appointment, and the resigning
Agent's rights, powers and duties as Agent shall be terminated, without any
other or further act or deed on the part of such former Agent or any of the
parties to this Credit Agreement.  After the retiring Agent's resignation
hereunder as Agent, the provisions of this Section 9 shall inure to its benefit
as to any actions taken or omitted to be taken by it while it was Agent under
this Credit Agreement.

within said 15 Business Day period, the resigning Agent with the consent of
ATel shall then appoint a successor Agent (which shall be an incorporated bank
or trust company or other qualified financial institution with operations in
the United States and total assets of at least $1 billion) who shall serve as
Agent until such time, if any, as the Required Banks appoint a successor Agent
as provided above.

                 (D)  If no successor Agent has been appointed pursuant to
subsection B or C by the 20th Business Day after the date such notice of
resignation was given by the resigning Agent, such Agent's resignation shall
become effective and the  Required Banks shall thereafter perform all the
duties of Agent hereunder until such time, if any, as the Required Banks
appoint a successor Agent as provided above.

         evidenced on the notice in the form of Exhibit D-1 hereto, may assign
         pursuant to an Assignment Agreement substantially in the form of
         Exhibit D-2 hereto all or a portion of its Loans, Notes and/or
         Commitments hereunder pursuant to this clause (b)(A) to (x) one or
         more Banks or (y) one or more accredited investors (as defined in SEC
         Regulation D).  Any assignment pursuant to this clause (b)(A) will
         become effective five Business Days after the Agent's receipt of (i) a
         written notice in the form of Exhibit D- 1 hereto from the assigning
         Bank and the assignee Bank and (ii) a processing and recordation fee
         of $2,000 from the assigning Bank in connection with the Agent's
         recording of such sale, assignment, transfer or negotiation; provided
         that such fee shall only be payable if the assignment is between a
         Bank and a party that is not a Bank prior to the assignment.  ATel
         shall issue new Notes to the assignee in conformity with Section 1.05
         and the assignor shall return the old Notes to ATel.  Upon  the
         effectiveness of any assignment in accordance with this clause (b)(A),
         the assignee will become a "Bank" for all purposes of this Credit
         Agreement and the other Credit Documents and, to the extent of such
         assignment, the assigning Bank shall be relieved of its obligations
         hereunder with respect to the Commitments being assigned.  The Agent
         shall maintain at its address specified in Annex II hereto a copy of
         each Assignment Agreement delivered to and accepted by it and a
         register in which it shall record the names and addresses of the Banks
         and the Commitment of, and principal amount of the Loans owing to,
         each Bank from time to time (the "Register").  The entries in the
         Register shall be conclusive and binding for all purposes, absent
         demonstrable error, and ATel, the Agent and the Banks may treat each
         Person whose name is recorded in the Register as a Bank hereunder for
         all purposes of this Credit Agreement.  The Register shall be
         available for inspection by ATel, the Agent or any Bank at any
         reasonable time and from time to time upon reasonable prior notice.

                 (B)  Participations.  Each Bank may transfer, grant or assign
         participations in all or any part of such Bank's
<PAGE>   77
                                     - 72 -

         Loans, Notes and/or Commitments hereunder pursuant to this clause
         (b)(B) to any Person; provided that (i) such Bank shall remain a
         "Bank" for all purposes of this Credit Agreement and the transferee of
         such participation shall not constitute a Bank hereunder and (ii) no
         participant under any such participation shall have rights to approve
         any amendment to or waiver of this Credit Agreement or any other
         Credit Document except to the extent such amendment or waiver would
         (x) change the scheduled final maturity date of any of the Loans,
         Notes or Commitments in which such participant is participating or (y)
         reduce the principal amount, interest rate or fees applicable to any
         of the Loans, Notes or Commitments in which such participant is
         participating or postpone the payment of any interest or fees or (z)
         release all or substantially all of the Collateral.  In the case of
         any such participation, the participant shall not have any rights
         under this Credit Agreement or any of the other Credit Documents (the
         participant's rights against the granting Bank in respect of such
         participation to be those set forth in the agreement with such Bank
         creating such participation) and all amounts payable by ATel hereunder
         shall be determined as if such Bank had not sold such participation;
         provided  that such participant shall be considered to be a "Bank" for
         purposes of Sections 10.02 and 10.06(b).

                 10.05.  No Waiver; Remedies Cumulative.  No failure or delay
on the part of the Agent or any Bank in exercising any right, power or
privilege hereunder or under any other Credit Document and no course of dealing
between ATel and the Agent or any Bank shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power, or privilege
hereunder or under any other Credit Document preclude any other or further
exercise thereof or the exercise of any other right, power or privilege
hereunder or thereunder.  The rights and remedies herein expressly provided are
cumulative and not exclusive of any rights or remedies which the Agent or any
Bank would otherwise have.  No notice to or demand on ATel in any case shall
entitle ATel to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Agent or the Banks to
any other or further action in any circumstances without notice or demand.

                 10.06.  Payments Pro Rata.  (a)  The Agent agrees that
promptly after its receipt of each payment from or on behalf of ATel in respect
of any Obligations of ATel, it shall distribute such payment to the Banks pro
rata based upon their
<PAGE>   78
                                     - 73 -

respective shares, if any, of the Obligations with respect to which such
payment was received.

                 (b)  Each of the Banks agrees that, if it should receive any
amount hereunder (whether by voluntary payment, by realization upon security,
by the exercise of the right of setoff or banker's lien, by counterclaim or
cross action, by the enforcement of any right under the Credit Documents, or
otherwise) which is applicable to the payment of the principal of, or interest
on, the Loans, of a sum which with respect to the related sum or sums received
by other Banks is in a greater proportion than the total of such Obligations
then owed and due to such Bank bears to the total of such Obligations then owed
and due to all of the Banks immediately prior to such receipt, then such Bank
receiving such excess payment shall purchase for cash without recourse or
warranty from the other Banks an interest in the Obligations of ATel to such
Banks in such amount as shall result in a proportional participation by all of
the Banks in such amount; provided that if all or any portion of such excess
amount is thereafter recovered from such Bank, such purchase shall be rescinded
and the purchase price restored to the extent of such recovery, but without
interest.

                 10.07.  Calculations; Computations.  (a)  The financial
statements to be furnished to the Banks pursuant hereto shall be made and
prepared in accordance with GAAP consistently applied throughout the periods
involved (except as set forth in the notes thereto or as otherwise disclosed in
writing by ATel to the Banks); provided that, except as otherwise specifically
provided herein, all computations determining compliance with Section 7 and all
definitions used herein for any purpose), shall utilize accounting principles
and policies in effect at the time of the preparation of, and in conformity
with those used to prepare, the historical financial statements delivered to
the Banks pursuant to Section 3.01(I).

                 (b)  All computations of interest and fees hereunder shall be
made on the actual number of days elapsed over a year of 365 days.

                 10.08.  Governing Law; Submission to Jurisdiction; Venue.  (a)
This Credit Agreement and the rights and obligations of the parties hereunder
shall be construed and enforced in accordance with and be governed by the laws
of the State of New York applicable to contracts made and to be performed
wholly therein.  Any legal action or proceeding with respect to this Credit
Agreement or any other Credit Document may be brought in the courts of the

serve process in any other manner permitted by law or to commence legal
proceedings or otherwise proceed against ATel in any other jurisdiction.

                 (b)  ATel hereby irrevocably waives any objection which it may

proceedings arising out of or in connection with this Credit Agreement or any
other Credit Document brought in the courts referred to in clause (a) above and
hereby further irrevocably waives and agrees not to plead or claim in any such

case of the Banks, shall have given to the Agent telephonic (confirmed in
writing), written, telex or telecopy notice (actually received) at such office

affected Bank and the Agent, (i) extend the scheduled final maturity date of
any Loan, or any portion thereof, or reduce the rate or extend the time of
payment of interest thereon or fees or reduce the principal amount thereof, or
increase the Commitments of any Bank over the amount thereof then in effect (it
being understood that a waiver of any Default or Event of Default or of a
mandatory reduction in the Loan Commitment shall not constitute a change in the
terms of any Commitment of any Bank), (ii) release all or substantially all of
the Collateral (except as expressly permitted by the Credit Documents), (iii)
amend, modify or waive any provision of this Section, or Sections 1.08, 2.04,

action is taken or condition exists.

                 10.17.  Confidentiality.  Except as may be required to enforce

         D.  All of the Guarantors' obligations hereunder shall be secured
pursuant to the Security Documents to which the Guarantors are a party.

         NOW, THEREFORE, in consideration of the foregoing premises and for
other good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, the Guarantors hereby agree as follows:

         Guarantee.  (a)  To induce the Banks to execute and deliver the Credit
Agreement and to make the Loans upon the terms and conditions set forth in the
Credit Agreement, and in consideration thereof, each of the Guarantors, jointly
and severally, hereby unconditionally and irrevocably (i) guarantees to the
Banks and their respective successors, endorsees, transferees and assigns, the
prompt and complete payment and performance when due (whether at the Final
Maturity Date, by acceleration or otherwise) and at all times thereafter of the
Obligations of the Borrower (including amounts which would become due but for
the operation of the automatic stay under Section 362(a) of the Bankruptcy
Code, or similar provisions under the bankruptcy laws of foreign jurisdictions)
and (ii) agrees to pay any and all reasonable expenses (including reasonable
attorneys' fees and disbursements) which may be paid or incurred by the Banks,
the Agent or the Collateral Agent in enforcing any rights with respect to, or
collecting, any or all of the Obligations and/or enforcing any rights with
respect to, or collecting against, the Guarantors under this Guarantee
(collectively, the "Guaranteed Obligations").

         (b) Each of the Guarantors agrees that this Guarantee 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, the Agent or any Bank
to any of the security held for payment of any of the Guaranteed Obligations or
to any balance of any deposit account or credit on the books of the Agent, the
Collateral Agent or any Bank in favor of the Borrower or any other Person.

         (c) No payment or payments made by the Guarantors or any other Person
or received or collected by the Banks (or the

Collateral Agent or Agent on behalf of the Banks) from the Guarantors or any
other Person by virtue of any action or proceeding or any set-off or
appropriation or application at any time in reduction of or in payment of the
Guaranteed Obligations shall be deemed to modify, reduce, release or otherwise
affect the liability or obligations of the Guarantors hereunder which shall,
notwithstanding any such payment or payments other than payments made to the
Banks (or the Collateral Agent or Agent on behalf of the Banks) by the
Guarantors or payments received or collected by the Banks (or the Collateral
Agent or Agent on behalf of the Banks) from the Guarantors, remain liable for
the Guaranteed Obligations until the Guaranteed Obligations are indefeasibly
paid in full in cash or cash equivalents, subject to the provisions of Section
1(d) hereof.

         (d) Notwithstanding any other provisions of this Guarantee, the
maximum aggregate amount of Guaranteed Obligations which each of the Guarantors
agrees to guarantee pursuant to this Guarantee shall equal the lesser of (i)
the excess of the fair saleable value of the property of such Guarantor over
the total liabilities of such Guarantor (including the maximum amount
reasonably expected to become due in respect of contingent liabilities, other
than any such contingent liabilities under the Credit Agreement and the other
Credit Documents), such excess to be determined on the date of this Guarantee
or the date on which, from time to time, such enforcement or realization is
effected, whichever is higher and, (ii) the maximum aggregate amount of
Guaranteed Obligations which does not render this Guarantee, as it relates to
such Guarantor, void or voidable under applicable laws relating to fraudulent
conveyance or fraudulent transfer.  Subject to the preceding sentence, each of
the Guarantors understands, agrees and confirms that this is a guarantee of
payment when due and not of collection and that each Bank may, from time to
time, enforce this Guarantee up to the full amount of the Guaranteed
Obligations owed to such Bank without proceeding against the Borrower, against
any security for the Guaranteed Obligations, against any other guarantor or
under any other guarantee covering the Guaranteed Obligations.

         Waiver by Guarantors.  Each of the Guarantors hereby waives absolutely
and irrevocably any claim which it may have against the Borrower or any of
their respective Affiliates by

reason of any payment to the Agent, Collateral Agent or any Bank, or to any
other Person pursuant to or in respect of this Guarantee, including any claims
by way of subrogation, contribution, reimbursement, indemnity or otherwise
until such time as the Obligations hereunder have been paid in full.

         Consent by Guarantors.  Each of the Guarantors hereby consents and
agrees that, without the necessity of any reservation of rights against any
Guarantor and without notice to or further assent by any Guarantor, any demand
for payment of any of the Guaranteed Obligations made by the Agent, the
Collateral Agent or any Bank may be rescinded by the Banks (or the Agent or
Collateral Agent on behalf of the Banks) and any of the Guaranteed Obligations
continued, and the Guaranteed Obligations, or the liability of any other party
upon or for any part thereof, or any collateral security or guarantee therefor
or right of offset with respect thereto, may, from time to time, in whole or in
part, be renewed, extended, amended, modified, accelerated, compromised,
waived,  surrendered or released by the Banks (or the Agent or the Collateral
Agent on behalf of the Banks); and the Credit Agreement or any other Credit
Document, or other guarantee or documents in connection therewith, or any of
them, may be amended, modified, supplemented or terminated, in whole or in
part, as the Banks (or the Agent or Collateral Agent on behalf of the Banks)
may deem advisable from time to time; and any Guarantee or right of offset or
any Collateral may be sold, exchanged, waived, surrendered or released, all
without the necessity of any reservation of rights against any Guarantor and
without notice to or further assent by any Guarantor, which will remain bound
hereunder, notwithstanding any such renewal, extension, modification,
acceleration, compromise, amendment, supplement, termination, sale, exchange,
waiver, surrender or release.  Neither the Banks nor the Agent or the
Collateral Agent shall have any obligation to protect, secure, perfect or
insure any Collateral or property at any time held as security for the
Guaranteed Obligations or this Guarantee.  When making any demand hereunder
against any Guarantor, the Agent, the Collateral Agent or the Banks may, but
shall be under no obligation to, make a similar demand on any other Borrower or
any such other guarantor, and any failure by the Agent, the Collateral Agent or
the Banks to make any such demand or to collect any payments from such other
Borrower or any such other guarantor or any release of such other Borrower or
any such other guarantor or any of the Guarantors' obligations or

liabilities hereunder shall not impair or affect the rights and remedies,
express or implied, or as a matter of law, of the Banks against any of the
Guarantors hereunder.  For the purposes hereof "demand" shall include the
commencement and continuance of any legal proceedings.

         Waivers; Successors and Assigns.  The Guarantors waive any and all
notice of the creation, renewal, extension or accrual of any of the Guaranteed
Obligations and notice of or proof of reliance by the Banks upon this Guarantee
or acceptance of this Guarantee, and the Guaranteed Obligations shall
conclusively be deemed to have been created, contracted or incurred in reliance
upon this Guarantee, and all dealings between any of the Guarantors and any
other guarantor or any of the Borrower, on the one hand, and the Banks, on the
other hand, shall likewise be conclusively presumed to have been had or
consummated in reliance upon this Guarantee.  Each of the Guarantors waives
diligence, presentment, protest, demand for payment and notice of default or
non-payment to or upon any guarantor, any of the Borrower or the Guarantors
with respect to the Guaranteed Obligations.  This Guarantee shall be  construed
as a continuing, absolute and unconditional Guarantee of payment without regard
to the validity, regularity or enforceability of the Credit Agreement, the
other Credit Documents, any of the Guaranteed Obligations or any guarantee
therefor or right of offset with respect thereto at any time or from time to
time held by the Banks and without regard to any defense (other than the
defense of payment), set off or counterclaim which may at any time be available
to or be asserted by any guarantor, or any of the Borrower against the Banks,
or by any other circumstance whatsoever (with or without notice to or knowledge
of the Guarantors) which constitutes, or might be construed to constitute, an
equitable or legal discharge of the Guaranteed Obligations, or any of the
Guarantors under this Guarantee, in bankruptcy or in any other instance, and
the obligations and liabilities of any of the Guarantors hereunder shall not be
conditioned or contingent upon the pursuit by the Banks or any other Person at
any time of any right or remedy against any guarantor, any of the Borrower or
against any other Person which may be or become liable or obligated in respect
of all or any part of the Guaranteed Obligations or against any collateral
security or guarantee therefor or right of offset with respect thereto.  This
Guarantee shall remain in full force and effect and be binding in accordance
with and to the extent of its terms upon

each of the Guarantors and the successors and assigns thereof, and shall inure
to the benefit of the Banks, and their respective successors, endorsees,
transferees and assigns (including each holder from time to time of Guaranteed
Obligations) until all of the Guaranteed Obligations and the obligations of the
Guarantors under this Guarantee shall have been satisfied by indefeasible
payment in full in cash or cash equivalents, notwithstanding that from time to
time during the term of the Credit Agreement any guarantor or any of the
Borrower may be released from all of its Guaranteed Obligations thereunder.

         Guarantee Secured.  Payment under this Guarantee is secured by
pledges, encumbrances and mortgages of Collateral pursuant to applicable
Security Documents in accordance with the Credit Agreement.  Reference is
hereby made to the Credit Agreement and the applicable Security Documents for a
description of the Collateral pledged and the right of the respective parties
to such property, to secure all the obligations of the Guarantors hereunder.

         Rights of Set-Off.  The Banks, and the Agent and Collateral Agent on
behalf of the Banks, are each hereby irrevocably authorized upon the occurrence
and during the  continuance of an Event of Default without notice to any of the
Guarantors (any such notice being expressly waived by any of the Guarantors to
the extent permitted by applicable law) to set-off and appropriate and apply
any and all deposits (general or special, time or demand, provisional or
final), in any currency, and any other credits, indebtedness or claims, in any
currency, in each case whether direct or indirect or contingent or matured or
unmatured, at any time held or owing by the Banks to or for the credit or the
account of any of the Guarantors, or any part thereof, in such amounts as the
Banks, or the Agent or Collateral Agent on behalf of the Banks, may elect,
against and on account of the obligations and liabilities of any of the
Guarantors to the Banks, in any currency, whether arising hereunder or
otherwise, as the Banks, or the Agent or Collateral Agent on behalf of the
Banks, may elect, whether or not the Banks, or the Agent or Collateral Agent on
behalf of the Banks, have made any demand for payment but only to the extent
that such obligations, liabilities and claims shall have become due and payable
(whether as stated, by acceleration or otherwise).  The Banks, or the Agent or
Collateral Agent on

behalf of the Banks, agree to notify the Guarantors promptly of any such
set-off and the application made by the Banks, or the Agent on behalf of the
Banks; provided, that the failure to give such notice shall not affect the
validity of such set-off and application.  The rights of the Banks, or the
Agent or Collateral Agent on behalf of the Banks, under this Section 6 are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) which the Banks, or the Agent or Collateral Agent on behalf
of the Banks, may otherwise have.

         Effectiveness; Reinstatement.  This Guarantee shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Guaranteed Obligations is rescinded or must
otherwise be restored or returned by the Banks upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of any guarantor or the Borrower, or
upon or as a result of the appointment of a receiver, intervenor or conservator
of, or trustee or similar officer for, any guarantor, the Borrower, or any
substantial part of its property, or otherwise, all as though such payments had
not been made.

         Payments of Guaranteed Obligations.  Each of the Guarantors hereby
guarantees that the Guaranteed Obligations will be paid for the ratable benefit
of the Banks without set-off or counterclaim in lawful currency of the United
States of America at the office of the Collateral Agent located at  1211_Avenue
of the Americas, 7th Floor, New York, New York 10036-8701.  Each of the
Guarantors shall make any payments required hereunder upon receipt of written
notice thereof from the Agent or Collateral Agent or any Bank; provided,
however, that the failure of the Agent or Collateral Agent or any Bank to give
such notice shall not affect Guarantors' obligations hereunder.

         Default.  If (x) the Borrower has failed to pay or perform when due
its Guaranteed Obligations or (y) there is an event with respect to the
Guarantors that would require or permit the acceleration pursuant to Section
7.04 of the Credit Agreement of any outstanding Loan, or (z) the Guarantors
obligations, if any, under the Credit Agreement are accelerated, then in the
case of clause (x) all of the

<PAGE>   97

                                      -8-

Guaranteed Obligations with respect to the Borrower and in the case of clause
(y) or clause (z) all of the Guaranteed Obligations shall be immediately due
and payable by the Guarantors, regardless of whether in the case of clause (x)
the payment of the Guaranteed Obligations has been accelerated or in the case
of clause (y) or clause (z) the Borrower is in default with respect to the
Guaranteed Obligations.

         Representations and Warranties.  To induce the Banks to enter into the
Credit Agreement and to make Loans thereunder, the Guarantors represent and
warrant to each Bank that the following statements are true, correct and
complete on and as of the Closing Date:

         Organization and Powers.  Each of the Guarantors has been duly
incorporated and is an existing corporation in good standing under the laws of
its jurisdiction of incorporation and has the  power and authority to own its
property and assets and to transact the business in which it is engaged and
proposes to engage.  Each of the Guarantors has duly qualified and is qualified
to do business and is in good standing in all jurisdictions in which the
conduct of its business or the ownership of its properties requires such
qualification, except where the failure to be so qualified would not have a
Materially Adverse Effect.  Each of the Guarantors has all requisite power and
authority and all requisite governmental licenses, authorizations, consents and
approvals to own and carry on its business as now conducted and as contemplated
to be conducted by the Documents, other than such licenses, authorizations,
consents and approvals the failure to obtain which has not had and will not
have a Materially Adverse Effect.  Each of the Guarantors has all authority to
enter into each of the Security  Documents to which it is or is to be a party
and to carry out the transactions contemplated thereby and to execute and
deliver this Guarantee.

         No Violations.  Neither the execution, delivery or performance by any
of the Guarantors of any of the Credit Documents to which it is, or is to be, a
party, nor compliance with any of the terms and provisions thereof, nor the
consummation of any of the transactions contemplated therein, nor the grant and
perfection of the security interests pursuant to the Security Documents (a)
will contravene any provision of





______________________________________

<PAGE>   98

                                      -9-

any law, statute, rule, regulation, order, writ, injunction or decree of any
Governmental Authority, (b) will conflict or be inconsistent with or result in
any breach of, any of the terms, covenants, conditions or provisions of, or
constitute (with notice or lapse of time or both) a default under any material
contractual obligation of any of the Guarantors, or (other than as contemplated
by the Security Documents) result in the creation or imposition of (or the
obligation to create or impose), any Lien upon any of the property or assets of
the Guarantors pursuant to any material contractual obligation or (c) will
violate any provision of the organizational documents of the Guarantors.

         Approvals.  The execution, delivery and performance by any of the
Guarantors of the Credit Documents to which it is, or is to be, a party do not
and will not require any registration with, consent or waiver or approval of,
or notice to, or other action to, with or by, any Governmental Authority or
other Person except filings required for the perfection of security interests
granted pursuant to the Security Documents.  All consents and approvals from or
notices to or filings with any Governmental Authority or other Person required
to be obtained by any Guarantor have been obtained and are in full force and
effect except where failure to obtain such consents, approvals, notices, etc.
would not have a Material Adverse Effect.

         Binding Obligation.  This Guarantee constitutes the legal, valid and
binding obligation of each of the Guarantors, enforceable, jointly and
severally, against each of the Guarantors in accordance with its terms except
as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws relating to or limiting creditors'
rights generally or by equitable principles relating to enforceability.

         Investment Company.  Each of the Guarantors is not an "investment
company" or a company "controlled" by an "investment company" (as each of such
quoted terms is defined or used in the Investment Company Act of 1940, as
amended) or subject to any foreign, federal or local statute or regulation
limiting its ability to incur indebtedness for money borrowed

or guarantee such indebtedness as contemplated hereby or by any other Credit
Document.

         Ratable Sharing.  The Banks by acceptance of this Guarantee agree
among themselves that with respect to all amounts received by them which are
applicable to the payment of obligations of each of the Guarantors under this
Guarantee, if the Banks, or the Agent or Collateral Agent on behalf of the
Banks, exercise their rights hereunder, including, without limitation,
acceleration of the obligations of each of the Guarantors hereunder, equitable
adjustment will be made so that, in effect, all such amounts will be shared
among the banks pro rata based on the relative outstanding Guaranteed
Obligations.

         Merger.  If any of the Guarantors shall merge into or consolidate with
another entity, or liquidate, wind up or dissolve itself in a transaction not
prohibited by the Credit Agreement, or if all of the stock of any of the
Guarantors shall be sold or otherwise disposed of in a manner not prohibited by
the Credit Agreement, such Guarantor hereby covenants and agrees, that upon any
such merger, consolidation, liquidation, or dissolution, the guarantee given in
this Guarantee and the due and punctual performance and observance of all of
the covenants and conditions of the Credit Agreement to be performed by such
Guarantor, shall be expressly assumed (in the event that any of such Guarantor
is not the surviving entity in the merger) by supplemental agreements
satisfactory in form to the Banks, or the Agent or Collateral Agent on behalf
of the Banks, by the entity or entities formed by such consolidation, or into
which such Guarantor shall have been merged, or by the entity or entities which
shall have acquired such property.  In addition, such Guarantor shall deliver
to the Banks, or the Agent or Collateral Agent on behalf of the Banks, an
Officers' Certificate and an opinion of counsel, each stating that such merger,
consolidation or transfer and such supplemental agreements comply with this
Guarantee and that all conditions precedent herein provided relating to such
transaction have been complied with.  In case of any such consolidation,
merger, sale or conveyance and upon the assumption by the successor entity or
entities, by supplemental agreements  executed and delivered to the Banks or
the Agent or Collateral Agent on behalf

of the Banks, and satisfactory in form to the Banks, or the Agent or Collateral
Agent on behalf of the Banks, of the guarantee given in this Guarantee and the
due and punctual performance of all of the covenants and conditions of the
Credit Agreement to be performed by such Guarantor, such successor entity or
entities shall succeed to and be substituted for such Guarantor, with the same
effect as if it or they had been named herein as a Guarantor.

         No Waiver.  No failure to exercise and no delay in exercising, on the
part of the Banks, or the Agent or Collateral Agent on behalf of the Banks, any
right, power or privilege hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any right, power or privilege preclude
any other or further exercise thereof, or the exercise of any other power or
right.  The rights and remedies herein provided are cumulative and not
exclusive of any rights or remedies provided by law.  In the event the Banks,
the Agent or the Collateral Agent on behalf of the Banks, shall have instituted
any proceeding to enforce any right, power or remedy under this Guarantee by
sale or otherwise, and such proceeding shall have been discontinued or
abandoned for any reason or shall have been determined adversely to the Banks,
the Agent or the Collateral Agent on behalf of the Banks, then and in every
such case, the Guarantors, the Banks, the Agent or the Collateral Agent on
behalf of the Banks, and each Bank shall be restored to its respective former
position and rights hereunder, and all rights, remedies and powers of the
Banks, the Agent or the Collateral Agent on behalf of the Banks, shall continue
as if no such proceeding had been instituted.

         Termination.  This Guarantee shall terminate and be of no further
force and effect, upon the payment and satisfaction of the Guaranteed
Obligations.

         Notices.  All notices, demands, instructions or other communications
required or permitted to be given to or made upon any party hereto shall be
given in accordance with the provisions of the Credit Agreement and at the
address either set forth therein or as provided on the signature page hereof.

         Amendments, Waivers, etc.  No provision of this Guarantee shall be
waived, amended, terminated or supplemented

Collateral Agent, on behalf of the Banks.

         Notice of Exercise.  Upon exercise of its rights hereunder, the Banks,
or the Agent or Collateral Agent on behalf of the Banks, as the case may be,

                                                         TO THE CREDIT AGREEMENT

                       MANAGEMENT SUBORDINATION AGREEMENT

         THIS MANAGEMENT SUBORDINATION AGREEMENT, dated as of February 26,
1997, is by and between American Telecasting, Inc., (the "Subordinated
Creditor"), and BANQUE INDOSUEZ, NEW YORK BRANCH, as Agent ("Banque").

         WHEREAS, the Subordinated Creditor, Banque, and the banks listed on
Annex I thereto (the "Banks") have entered into a Credit Agreement dated as of
even date herewith (such Credit Agreement, together with any supplements,
restatements, modifications and amendments, is hereinafter referred to as the
"Credit Agreement") pursuant to which the Subordinated Creditor has incurred
certain monetary obligations to the Banks (the "Senior Debt");

         WHEREAS, the Subordinated Creditor has entered into management
agreements with each of its Subsidiaries (each such management agreement, an
"Operating Agreement" and collectively, the "Operating Agreements") pursuant to
which, among other things, the Subordinated Creditor will provide management
services to such Subsidiaries in return for management fees and reimbursement
for costs and expenses as required by each of their respective Operating
Agreements; and

         WHEREAS, it is a condition under the terms of the Credit Agreement
that all payments pursuant to each Operating Agreement be subordinated to the
Senior Debt (such payments are hereinafter referred to as the "Subordinated
Payments").

         NOW, THEREFORE, in consideration of the foregoing and of the premises
herein contained, the parties agree as follows:

         Any capitalized terms not otherwise defined herein shall have the
meanings set forth in the Credit Agreement.

______________________________________


         The Subordinated Creditor agrees to subordinate and does hereby
subordinate, all payments by each of its Subsidiaries of the Subordinated
Payments to any payments to the Banks with respect to the Senior Debt and
further agrees as follows:

             except as provided in paragraph 3 hereof,  not to accept payment
which may be due with respect to, and not to demand, sue for, take or receive
all or any part of the  Subordinated Payments or any interest thereon, unless
and until any and all of the Senior Debt shall have been fully paid and
discharged;

             not to modify, amend or waive any of the terms or conditions of
any agreement relating to the Subordinated Payments (including without
limitation each of the Operating Agreements) without the prior written consent
of Banque;

             that, except as provided in paragraph 3 hereof, if any payments
are made on account of the Subordinated Payments, each and every amount so paid
will be forthwith paid to Banque to be credited and applied by Banque as Agent
upon the Senior Debt as provided in the Credit Agreement whether matured or
unmatured at such time, and until so paid shall hold such payments in
segregated amounts and in trust for the benefit of the Banks.

             that, in the event of any insolvency or bankruptcy proceedings, or
any receivership, liquidation, or reorganization or other similar proceedings
in connection therewith, relating to any Subsidiary of the Subordinated
Creditor, or to any of such Subsidiary's respective properties, or in the event
of any proceedings for voluntary liquidation, dissolution or other winding up
of any such Subsidiary, whether or not involving insolvency or bankruptcy, the
Banks shall be entitled to receive payment in full of the Senior Debt before
the Subordinated Creditor is entitled to receive any payment on account of the
Subordinated Payments, and to enable the Banks to assert and enforce their
rights hereunder in any such action or proceedings, or upon the happening of
any such event, Banque is irrevocably authorized and empowered, in its
discretion, as the Subordinated Creditor's attorneys-in-fact or otherwise, to

______________________________________


make and present, for and on behalf of the Subordinated Creditor, such proofs
of claim against any such Subsidiary on account of any or all of the
Subordinated Payments as it may in good faith deem advisable, and to receive
and collect any and all interest or other payments or disbursements made
thereon, and to apply the same in its discretion upon the Senior Debt for the
benefit of the Banks;

             that in the event the Subordinated Payments are, or any part
thereof is, declared due and payable before maturity because of the existence
of default (under circumstances where the provisions of the foregoing clause
(d) are not applicable) ("Acceleration") then the Banks shall be entitled to
receive payment in full of the Senior Debt before the  Subordinated Creditor
shall be entitled to receive any payment on account of the Subordinated
Payments;

             not to commence any action or proceeding against any of its
Subsidiaries or any of its Subsidiaries' assets to recover all or any part of
the Subordinated Payments or exercise any right it may have as a secured party
of any of its Subsidiaries with respect to any of its assets or bring or join
with any creditor, unless Banque shall also join, on behalf of the Banks, in
bringing any proceedings against any such Subsidiary under any bankruptcy,
reorganization, readjustment of debt, arrangement of debt, receivership,
liquidation or insolvency law or statute of the federal or any state
government;

             not to transfer, assign, encumber or subordinate at any time while
this Agreement remains in effect, any right, claim or interest of any kind in
or to any of the Subordinated Payments and/or any interest thereon, unless the
same is done expressly subject to the terms or provisions of this Agreement;

             that Banque, on behalf of the Banks,  may at any time in its
discretion renew or extend the time of payment of all or any exiting or future
indebtedness or obligations of any Subsidiary of the Subordinated Creditor to
the Banks or waive any rights or release any collateral relative thereto at any
time or times, and, with reference thereto, make and enter into such agreements
as it may deem proper or desirable without

notice to or further assent of the Subordinated Creditor and all without in any
manner impairing or affecting this Agreement or any of the Banks' rights
hereunder, and

             that any collateral security securing such Subordinated Payments
shall be expressly made subordinate and junior to any lien in the same
collateral securing Senior Debt, and the Subordinated Creditor will promptly
file notices or instruments in all appropriate public offices to give public
notice of this subordination.

         Notwithstanding paragraph 2 hereof, each Subsidiary of the
Subordinated Creditor may pay to the Subordinated Creditor, and the
Subordinated Creditor may retain for itself, current and earned payments (which
payments otherwise would constitute Subordinated Payments hereunder) pursuant
to the Operating Agreements so long as no Event of Default (or event which with
notice or a lapse of time would become an Event of  Default) has occurred and
is continuing under the Credit Agreement at the time of such payment, or would
occur immediately after giving effect to such payment.

         The Subordinated Creditor hereby represents and warrants to Banque as
follows:

             The Subordinated Creditors (i) is a corporation duly formed,
validly existing, and in good standing under the laws of the jurisdiction of
its incorporation; (ii) has the power and authority to own its assets and to
transact the business in which it is now or in which it proposes to be engaged;
(iii) and is duly qualified as a foreign entity to do business and is in good
standing in all jurisdictions in which any of its activities or the ownership
of its properties makes such qualification necessary, except where the failure
to so qualify would not have a material adverse effect on the business or
properties of the Subordinated Creditor.

             The execution, delivery and performance by the Subordinated
Creditor of this Agreement has been duly authorized by all necessary corporate
actions and does not and will not:  (i) require any consent or approval of each
of the

______________________________________


Subordinated Creditor's board of directors or shareholders or any other person
that has not been obtained; (ii) conflict with, or result in the breach of, or
constitute a default under, any of the terms, conditions or provisions of (A)
the Subordinated Creditor's certificate of incorporation or by-laws, (B) any
law or any regulation applicable to the Subordinated Creditor, (C) any order,
writ, injunction or decree of any court or governmental instrumentality
applicable to the Subordinated Creditor, (D) any agreement or instrument to
which the Subordinated Creditors is subject, which conflict, breach or default
would have a material adverse effect on the business or properties of the
Subordinated Creditor or the ability of the Subordinated Creditor to execute,
deliver or perform this Agreement, or (iii) result in the creation or
imposition of any Lien (other than in favor of the Banks) upon the Subordinated
Creditor's properties or assets pursuant to the terms of any such agreement or
instrument or otherwise.

             No authorization or approval or other action by, and no notice to
or filing with, any Governmental Authority or other regulatory body is required
for the due execution, delivery and performance by the Subordinated Creditor of
this Agreement.

             This Agreement is a legal, valid and binding obligation of the
Subordinated Creditor, enforceable against the Subordinated Creditor in
accordance with its terms except to the extent that such enforcement may be
limited by applicable bankruptcy, insolvency and other similar laws affecting
creditors' rights generally.

             There is no action, suit or proceeding pending or, to the
knowledge of the Subordinated Creditor, threatened against or otherwise
affecting the Subordinated Creditor before any court or other governmental
instrumentality or any arbitrator which would, in any one case or in the
aggregate, materially adversely affect the ability of the Subordinated Creditor
to perform its obligations under this Agreement.

             All notices, requests and demands to or upon the respective
parties hereto to be effective shall be in writing or by telecopier (fax) and,

         ..  Waivers; Amendments.  No failure or delay of the Holder 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 Holder are cumulative and not
exclusive of any rights or remedies which it would otherwise have.  The
provisions of this Debt Debt Warrant may be amended, modified or waived with
(and only with) the written consent of the Company and the Holders of a
majority of the Debt Warrants; provided, however, that no such amendment,
modification or waiver shall, without the written consent of each Debt
Warrantholder whose interest might be adversely affected by such amendment,
modification or waiver, (a) change the principal amount of Loan subject to
issuance upon exercise of this Debt Debt Warrant, the Put Amount or provisions
for payment thereof or (b) amend, modify or waive the provisions of this
Section or Article III.

         Any such amendment, modification or waiver effected pursuant to this
Section shall be binding upon the holders of  all Debt Debt Warrants, upon each
future holder thereof and upon the Company.  In the event of any such
amendment, modification or waiver the Company shall give prompt notice thereof
to all Debt Warrantholders and, if appropriate, notation thereof shall be made
on all Debt Debt Warrants thereafter surrendered for registration of transfer
or exchange.

         No notice or demand on the Company in any case shall entitle the
Company to any other or further notice or demand in similar or other
circumstances.

         ..  Governing Law.  This Debt Debt Warrant shall be construed in
accordance with and governed by the laws of the

THIS WARRANT AND THE SHARES OF COMMON STOCK PURCHASABLE HEREUNDER HAVE NOT BEEN

SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION AND MAY NOT BE SOLD, OFFERED
FOR SALE OR OTHERWISE TRANSFERRED UNLESS REGISTERED OR QUALIFIED UNDER SAID ACT

                                                        Dated: February 26, 1997

         THIS IS TO CERTIFY THAT, for value received, INDOSUEZ CM_II, INC. or

after the Exercise Period (as hereinafter defined) has expired and prior to
5:00 p.m., New York City time, on February 25, 2007 at the place where a
Warrant Agency (as hereinafter defined) is located, at the Exercise Price (as
hereinafter defined), the number of shares of Class A Common Stock, par value
$0.01 per share (the "Common Stock"), of the Company shown above, all subject
to adjustment and upon the terms and conditions as hereinafter provided, and is
entitled also to exercise the other appurtenant rights, powers and privileges
hereinafter described.  This Warrant is also subject to adjustment pursuant to
the Option Agreement (as hereinafter defined).  This Warrant is one of one or
more warrants (the "Warrants") of the same  form and having the same terms as
this Warrant.

         Certain terms used in this Warrant are defined in Article V.

                                    ARTICLE

                              EXERCISE OF WARRANTS

         ..  Method of Exercise.  To exercise this Warrant in whole or in part,
the Holder shall deliver to the Company, at the Warrant Agency, (a) this
Warrant, (b) a written notice, in substantially the form of the Subscription
Notice attached hereto, of such Holder's election to exercise this Warrant,
which notice shall specify the number of shares of Common Stock to be
purchased, the denominations of the share certificate or certificates desired
and the name or names in which such certificates are to be registered, and (c)
payment of the Exercise Price with respect to such shares.  Notwithstanding the
foregoing, this Warrant shall be exercisable only, to the extent and at the
time or times, that the Holder could legally take possession and title of such
shares.  Payment made pursuant to clause (c) above may be made, at the option
of the Holder: (x) by cash, money order, certified or bank cashier's check or
wire transfer or (y) the delivery of a notice to the Company that the Holder is
exercising this Warrant by

authorizing the Company to reduce the number of shares of Common Stock subject
to this Warrant by the number of shares having an aggregate value equal to the
aggregate Exercise Price.

         The Company shall, as promptly as practicable and in any event within
three Business Days thereafter, execute and deliver or cause to be executed and
delivered, in accordance with such notice, a certificate or certificates
representing the aggregate number and type of shares of Common Stock specified
in said notice.  The share certificate or certificates so delivered shall be in
such denominations as may be specified in such notice or, if such notice shall
not specify denominations, shall be in the amount of the number of shares of
Common Stock for which the Warrant is being exercised, and shall be issued in
the name of the Holder or such other name or names as shall be designated in
such notice.  Such certificate or certificates shall be deemed to have been
issued, and such Holder or any other Person so designated to be named therein
shall be deemed for all purposes to have become a holder of record of such
shares, as of the date the aforementioned notice is received by the Company.
If this Warrant shall have been exercised only in part, the Company shall, at
the time of delivery of the certificate or certificates, deliver to the Holder
a new Warrant evidencing the rights to purchase the remaining shares of Common
Stock called for by this Warrant, which new Warrant shall in all other respects
be identical with this Warrant, or, at the request of the Holder, appropriate
notation may be made on this Warrant which shall then be returned to the
Holder.  The Company shall pay all expenses, taxes and other charges payable in
connection with the preparation, issuance and delivery of share certificates
and new Warrants, except that, if share certificates or new Warrants shall be
registered in a name or names other than the name of the Holder, funds
sufficient to pay all transfer taxes payable as a result of such transfer shall
be paid by the Holder at the time of delivering the aforementioned notice of
exercise or promptly upon receipt of a written request of the Company for
payment.

         ..  Shares To Be Fully Paid and Nonassessable.  All shares of Common
Stock issued upon the exercise of this Warrant shall be validly issued, fully
paid and nonassessable and free from all preemptive rights of any stockholder,
and from all taxes, liens and charges with respect to the issue

thereof (other than transfer taxes) and, if the Common Stock is then listed on
any national securities exchanges (as defined in the Exchange Act) or quoted on
NASDAQ, be duly listed or quoted thereon, as the case may be.

         ..  No Fractional Shares To Be Issued.  The Company shall not be
required to issue fractions of shares of Common Stock upon exercise of this
Warrant.  If any fraction of a share would, but for this Section, be issuable
upon any exercise of this Warrant, and if the Company shall have elected not to
issue such fraction of a share, in lieu of such fractional share the Company
shall pay to the Holder, in cash, an amount equal to such fraction of the Fair
Market Value per share of outstanding Common Stock of the Company on the
Business Day immediately prior to the date of such exercise.

         ..  Share Legend.  Each certificate for shares of Common Stock issued
upon exercise of this Warrant, unless at the time of exercise such shares are
registered under the Securities Act, shall bear the following legend:

    "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
    AMENDED, OR UNDER THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION
    AND MAY NOT BE SOLD, OFFERED FOR SALE OR OTHERWISE TRANSFERRED UNLESS
    REGISTERED OR QUALIFIED UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS
    OR  UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY
    SATISFACTORY TO THE COMPANY THAT REGISTRATION, QUALIFICATION OR OTHER SUCH
    ACTIONS ARE NOT REQUIRED UNDER SAID ACT.  THE OFFERING OF THIS SECURITY HAS
    NOT BEEN REVIEWED OR APPROVED BY ANY STATE SECURITIES ADMINISTRATOR.  THIS
    SECURITY IS BENEFITED BY AND SUBJECT TO A REGISTRATION RIGHTS AGREEMENT,
    DATED AS OF FEBRUARY 25, 1997, BY AND AMONG THE COMPANY AND THE OTHER
    PARTIES LISTED THEREIN, A COPY OF WHICH IS ON FILE WITH THE COMPANY AND
    WILL BE FURNISHED UPON WRITTEN REQUEST AND WITHOUT CHARGE."

         Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon
completion of a public distribution





______________________________________

<PAGE>   158

______________________________________


pursuant to a registration statement under the Securities Act) shall also bear
such legend unless, in the opinion of counsel selected by the holder of such
certificate (who may be an employee of such holder) reasonably satisfactory to
the Company, the securities represented thereby are no longer subject to
restrictions on resale under the Securities Act.

         ..  Reservation; Authorization.  The Company has reserved and will
keep available for issuance upon exercise of the Warrants the total number of
shares of Common Stock deliverable upon exercise of all Warrants from time to
time outstanding.  The issuance of such shares has been duly and validly
authorized and, when issued and sold in accordance with the Warrants, such
shares will be duly and validly issued, fully paid and nonassessable.

                                    ARTICLE

                       WARRANT AGENCY; TRANSFER, EXCHANGE

                          AND REPLACEMENT OF WARRANTS

         ..  Warrant Agency.  If the Requisite Holders shall request
appointment of an independent warrant agency with respect to the Warrants, the
Company shall promptly appoint and thereafter maintain, at its own expense, an
agency, which agency may be the Company's then existing transfer agent (the
"Warrant Agency"), for certain purposes specified herein, and shall give prompt
notice of such appointment (and appointment of any successor Warrant Agency) to
all holders of Warrants.  Until an independent Warrant Agency is so appointed,
the Company shall perform the obligations of the Warrant Agency  provided
herein at its address at _______________________________ or such other address
as the Company shall specify by notice to all Warrantholders.

<PAGE>   159

______________________________________


         ..  Ownership of Warrant.  The Company may deem and treat the Person
in whose name this Warrant is registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by any
Person other than the Warrant Agency) for all purposes and shall not be
affected by any notice to the contrary, until presentation of this Warrant for
registration of transfer as provided in this Article II.

         ..  Transfer of Warrant.  The Company agrees to maintain at the
Warrant Agency books for the registration of transfers of the Warrants, and
transfer of this Warrant and all rights hereunder shall be registered, in whole
or in part, on such books, upon surrender of this Warrant at the Warrant
Agency, together with a written assignment of this Warrant duly executed by the
Holder or his duly authorized agent or attorney, with (unless the Holder is the
original Warrantholder) signatures guaranteed by a bank or trust company or a
broker or dealer registered with the NASD, and funds sufficient to pay any
transfer taxes payable upon such transfer.  Upon surrender the Company shall
execute and deliver a new Warrant or Warrants in the name of the assignee or
assignees and in the denominations specified in the instrument of assignment,
and this Warrant shall promptly be cancelled.  Notwithstanding the foregoing, a
Warrant may be exercised by a new holder in accordance with the procedures set
forth herein without having a new Warrant issued.  The Warrant Agency shall not
be required to register any transfers if the Holder fails to furnish to the
Company, after a request therefor, an opinion of counsel reasonably
satisfactory to the Company that such transfer is exempt from the registration
requirements of the Securities Act; provided that the Company agrees not to
request an opinion of counsel with respect to transfers by an affiliate of
Banque Indosuez to its employees so long as such persons furnish documentation
reasonably satisfactory to the Company.

         ..  Division or Combination of Warrants.  This Warrant may be divided
or combined with other Warrants upon surrender hereof and of any Warrant or
Warrants with which this Warrant is to be combined at the Warrant Agency,
together with a written notice specifying the names and denominations in which
the new Warrant or Warrants are to be issued, signed by the holders hereof and
thereof or their respective duly authorized agents or attorneys.  Subject to
compliance with Section  2.3 as to any transfer which may be involved in the





______________________________________

<PAGE>   160

______________________________________


division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

         ..  Loss, Theft, Destruction or Mutilation of Warrants.  Upon receipt
of evidence satisfactory to the Company of the loss, theft, destruction or
mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security reasonably satisfactory to
the Company (the original Warrantholder's indemnity being satisfactory
indemnity in the event of loss, theft or destruction of any Warrant owned by
such holder), or, in the case of any such mutilation, upon surrender and
cancellation of such Warrant, the Company will make and deliver, in lieu of
such lost, stolen, destroyed or mutilated Warrant, a new Warrant of like tenor
and representing the right to purchase the same aggregate number of shares of
Common Stock as provided for in such lost, stolen, destroyed or mutilated
Warrant.

         ..  Expenses of Delivery of Warrants.  The Company shall pay all
expenses, taxes (other than transfer taxes or income taxes of a Holder) and
other charges payable in connection with the preparation, issuance and delivery
of Warrants and shares issuable upon exercise of the Warrants hereunder.

                                    ARTICLE

                                 CERTAIN RIGHTS

         ..  Registration Rights.  The Common Stock issuable upon exercise of
this Warrant is entitled to the benefits of the Registration Rights Agreement
dated as of February 25, 1997, by and among the Company and the other parties
listed therein (the "Registration Rights Agreement").  The Company shall keep a
copy of the Registration Rights

Agreement, and any amendments thereto, at the Warrant Agency and shall furnish
copies thereof to the Holder upon request.

         ..  Contest and Appraisal Rights.  Upon each determination of Fair
Market Value hereunder (other than a determination relating solely to setting
the value of fractional shares), the Company shall promptly give notice thereof
to all Warrantholders, setting forth in reasonable detail the calculation of
such Fair Market Value and the method and basis of determination thereof, as
the case may be.  If the Requisite Holders shall disagree with such
determination and shall, by  notice to the Company given within 30 days after
the Company's notice of such determination, elect to dispute such
determination, such dispute shall be resolved in accordance with this Section
3.2.  In the event that a determination of Market Price, or a determination of
Fair Market Value solely involving Market Price, is disputed, such dispute
shall be submitted, at the Company's expense, to a New York Stock Exchange
member firm selected by the Company and acceptable to the Warrantholders, whose
determination of Fair Market Value and/or Market Price, as the case may be,
shall be binding on the Company and the Warrantholders.  In the event that a
determination of Fair Market Value, other than a determination solely involving
Market Price, is disputed, such dispute shall be resolved through the Appraisal
Procedure.

         ..  Certain Covenants.  The Company covenants and agrees that, until
exercise or cancellation of this Warrant, the Company will deliver to each
Holder:

         ()    As soon as available but not later than ninety (90) days after
the close of the fiscal year of the Company, a consolidated balance sheet of
the Company as at the end of such year and the related consolidated and
consolidating statements of income, of stockholders' equity and of cash flows
for such year, such consolidated statements to be audited by Arthur Andersen
LLP or other "Big Six" accounting firm;

         ()    As soon as available but not later than forty-five (45) days
after the end of each quarter, a consolidated balance sheet of the Company as

         ..  Adjustments Generally.  The Exercise Price and the number of
shares of Common Stock (or other securities or property) issuable upon exercise
of this Warrant shall be subject to adjustment from time to time upon the
occurrence of certain events, as provided in this Article IV.

         ..  Common Stock Reorganization.  If the Company shall after the date
of issuance of this Warrant subdivide its outstanding shares of Common Stock
into a greater number of shares or consolidate its outstanding shares of Common
Stock into a smaller number of shares (any such event being called a "Common
Stock Reorganization"), then (a) the Exercise Price shall be adjusted,
effective immediately after the record date at which the holders of shares of
Common Stock are determined for purposes of such Common Stock Reorganization,
to a price determined by multiplying the Exercise Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
number of shares of Common

Stock outstanding on such record date before giving effect to such Common Stock
Reorganization and the denominator of which shall be the number of shares of
Common Stock outstanding after giving effect to such Common Stock
Reorganization, and (b) the number of shares of Common Stock subject to
purchase upon exercise of this Warrant shall be adjusted, effective at such
time, to a number determined by multiplying the number of shares of Common
Stock subject to purchase immediately before such Common Stock Reorganization
by a fraction, the numerator of which shall be the number of shares outstanding
after giving effect to such Common Stock Reorganization and the denominator of
which shall be the number of shares of Common Stock outstanding immediately
before such Common Stock Reorganization.

         ..  Common Stock Distribution.  ()  If the Company shall after the
date of issuance of this Warrant issue or otherwise sell or distribute any
shares of Common Stock, otherwise than pursuant to a Common Stock
Reorganization (any such event, including any event described in paragraphs (b)
and (c) below, being herein called a "Common Stock Distribution"), if such
Common Stock Distribution shall be for a consideration per share less than the
Fair Market Value per share of outstanding Common Stock of the Company on the
date of such Common Stock Distribution, or on the first date of the
announcement of such Common Stock Distribution (whichever is less), then,
effective  upon such Common Stock Distribution, the number of shares of Common
Stock purchasable upon exercise of this Warrant shall be adjusted by
multiplying the number of shares of Common Stock subject to purchase upon
exercise of this Warrant by a fraction, the numerator of which shall be the
total number of shares of Common Stock outstanding (and issuable upon exercise
or conversion of outstanding options, warrants and convertible securities)
immediately prior to such Common Stock Distribution plus the number of shares
of Common Stock issued (or deemed to be issued pursuant to paragraphs (b) and
(c) below) in such Common Stock Distribution and the denominator of which shall
be an amount equal to the sum of (A) the number of shares of Common Stock
outstanding (and issuable upon exercise or conversion of outstanding options,
warrants and convertible securities) immediately prior to such Common Stock
Distribution, plus (B) the number of shares of Common Stock which the aggregate
consideration, if any, received by the Company (determined as provided below)
for such Common Stock

Distribution would buy at the Fair Market Value thereof, as of the date
immediately prior to such Common Stock Distribution or as of the date
immediately prior to the date of announcement of such Common Stock Distribution
(whichever is less).  In the event of any such adjustment, the Exercise Price
for each Warrant shall be adjusted to a number determined by dividing the
Exercise Price immediately prior to such Common Stock Distribution by the
fraction used for purposes of the aforementioned adjustment.

         The provisions of this paragraph (a), including by operation of
paragraph (b) or (c) below, shall not operate to increase the Exercise Price or
to reduce the number of shares of Common Stock subject to purchase upon
exercise of this Warrant.

         ()    If the Company shall after the date of issuance of this Warrant
issue, sell, distribute or otherwise grant in any manner (whether directly or
by assumption in a merger or otherwise) any rights to subscribe for or to
purchase, or any warrants or options for the purchase of, Common Stock or any
stock or securities convertible into or exchangeable for Common Stock including
the Company's Class B Common Stock (such rights, warrants or options being
herein called "Options" and such convertible or exchangeable stock or
securities being herein called "Convertible Securities"), whether or not such
Options or the rights to convert or exchange any such Convertible Securities
are immediately exercisable, and the price per share for which Common Stock is
issuable upon the exercise of such Options or upon conversion or exchange of
such Convertible  Securities (determined by dividing (i) the aggregate amount,
if any, received or receivable by the Company as consideration for the granting
of such Options, plus the minimum aggregate amount of additional consideration
payable to the Company upon the exercise of all such Options, plus, in the case
of Options to acquire Convertible Securities, the minimum aggregate amount of
additional consideration, if any, payable upon the issue or sale of such
Convertible Securities and upon the conversion or exchange thereof, by (ii) the
total maximum number of shares of Common Stock issuable upon the exercise of
such Options or upon the conversion or exchange of all such Convertible
Securities issuable upon the exercise of such Options) shall be less than the
Fair Market Value per share of outstanding Common Stock of the Company on the
date of granting such Options or on the date of announcement thereof (whichever
is less), then for purposes of paragraph (a) above, the total maximum number of
shares of Common Stock issuable upon the

exercise of such Options or upon conversion or exchange of the total maximum
amount of such Convertible Securities issuable upon the exercise of such
Options shall be deemed to have been issued as of the date of granting of such
Options and thereafter shall be deemed to be outstanding and the Company shall
be deemed to have received as consideration such price per share, determined as
provided above, therefor.  Except as otherwise provided in paragraph (d) below,
no additional adjustment of the number of shares of Common Stock purchasable
upon the exercise of this Warrant or of the Exercise Price shall be made upon
the actual exercise of such Options or upon conversion or exchange of such
Convertible Securities.

         ()    If the Company shall after the date of issuance of this Warrant
issue, sell or otherwise distribute or grant (whether directly or by assumption
in a merger or otherwise) any Convertible Securities, whether or not the rights
to exchange or convert thereunder are immediately exercisable, and the price
per share for which Common Stock is issuable upon such conversion or exchange
(determined by dividing (i) the aggregate amount received or receivable by the
Company as consideration for the issue, sale or distribution of such
Convertible Securities, plus, the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the conversion or exchange
thereof, by (ii) the total maximum number of shares of Common Stock issuable
upon the conversion or exchange of all such Convertible Securities) shall be
less than the Fair Market Value per share of outstanding Common Stock of the
Company on the date of such issue, sale or distribution or on the date of
announcement thereof (whichever is less), then,  for purposes of paragraph (a)
above, the total maximum number of shares of Common Stock issuable upon
conversion or exchange of all such Convertible Securities shall be deemed to
have been issued as of the date of the issue, sale or distribution of such
Convertible Securities and thereafter shall be deemed to be outstanding and the
Company shall be deemed to have received as consideration such price per share,
determined as provided above, therefor.  Except as otherwise provided in
paragraph (d) below, no additional adjustment of the number of shares of Common
Stock purchasable upon exercise of this Warrant or of the Exercise Price shall
be made upon the actual conversion or exchange of such Convertible Securities.

         ()    If the purchase price provided for in any Option referred to in
paragraph (b) above, the additional

consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in paragraph (b) or (c) above, or the rate
at which any Convertible Securities referred to in paragraph (b) or (c) above
are convertible into or exchangeable for Common Stock shall change at any time
(other than under or by reason of provisions designed to protect against, and
having the effect of protecting against, dilution upon an event which results
in a related adjustment pursuant to this Article IV), the number of shares of
Common Stock purchasable upon exercise of this Warrant and the Exercise Price
then in effect shall forthwith be readjusted (effective only with respect to
any exercise of this Warrant after such readjustment) to the number of shares
of Common Stock purchasable upon exercise of this Warrant and the Exercise
Price which would then be in effect had the adjustment made upon the issue,
sale, distribution or grant of such Options or Convertible Securities been made
based upon such changed purchase price, additional consideration or conversion
rate, as the case may be; provided, however, that such readjustment shall give
effect to such change only with respect to such Options and Convertible
Securities as then remain outstanding.  If, at any time after any adjustment of
the number of shares of Common Stock purchasable upon exercise of each Warrant
or the Exercise Price shall have been made pursuant to this Article IV on the
basis of the issuance of any Option or Convertible Securities or after any new
adjustments of the number of shares of Common Stock purchasable upon exercise
of each Warrant or the Exercise Price shall have been made pursuant to this
paragraph, the right of conversion, exercise or exchange in such Option or
Convertible Securities shall expire or terminate, and the right of conversion,
exercise or exchange in respect of a portion of such Option or Convertible
Securities shall not have been exercised, such  previous adjustment shall be
rescinded and annulled.  Thereupon, a recomputation shall be made of the effect
of such Option or Convertible Securities on the basis of treating the number of
shares of Common Stock, if any, theretofore actually issued or issuable
pursuant to the previous exercise of such right of conversion, exercise or
exchange as having been issued on the date or dates of such conversion,
exercise or exchange and for the consideration actually received and receivable
therefor, and treating any such Option or Convertible Securities which then
remain outstanding as having been granted or issued immediately after the time
of any such issuance for the consideration per share for which shares of Common
Stock are issuable under such Option or Convertible Securities; and, if and to
the extent called for by the foregoing provisions of

this Section on the basis aforesaid, a new adjustment of the number of shares
of Common Stock purchasable upon exercise of each Warrant and the Exercise
Price shall be made, which new adjustment shall supersede (effective only with
respect to any exercise of this Warrant after such readjustment) the previous
adjustment so rescinded and annulled.

         ()    If the Company shall after the date of issuance of this Warrant
pay a dividend or make any other distribution upon any capital stock of the
Company payable in Common Stock, Options or Convertible Securities, then, for
purposes of paragraph (a) above, such Common Stock, Options or Convertible
Securities, as the case may be, shall be deemed to have been issued or sold
without consideration.

         ()    If any shares of Common Stock, Options or Convertible Securities
shall be issued, sold or distributed for cash, the consideration received
therefor shall be deemed to be the amount received by the Company therefor net
of any underwriting commissions or concessions paid or allowed by the Company
in connection therewith.  If any shares of Common Stock, Options or Convertible
Securities shall be issued, sold or distributed for a consideration other than
cash, the amount of the consideration other than cash received by the Company
shall be deemed to be the Fair Market Value of such consideration, after
deduction of any expenses incurred and any underwriting commissions or
concessions paid or allowed by the Company in connection therewith.  If any
shares of Common Stock, Options or Convertible Securities shall be issued in
connection with any merger in which the Company is the surviving corporation,
the amount of consideration therefor shall be deemed to be the Fair Market
Value of such portion of the assets and business of the nonsurviving
corporation as shall be attributable to such  Common Stock, Options or
Convertible Securities, as the case may be.  If any Options shall be issued in
connection with the issue and sale of other securities of the Company, together
comprising one integral transaction in which no specific consideration is
allocated to such Options by the parties thereto, such Options shall be deemed
to have been issued for consideration to be determined pursuant to the
Appraisal Procedure.

         ()    If the Company shall take a record of the holders of the Common
Stock for the purpose of entitling them to

receive a dividend or other distribution payable in Common Stock, Options or
Convertible Securities or to subscribe for or purchase Common Stock, Options or
Convertible Securities, then such record date shall be deemed to be the date of
the issue, sale, distribution or grant of the shares of Common Stock deemed to
have been issued or sold upon the declaration of such dividend or the making of
such other distribution or the date of the granting of such right of
subscription or purchase, as the case may be.

         ()    For purposes of determining whether any adjustment is required
pursuant to this Article IV, any security of the Company having rights
substantially equivalent to the Common Stock as to dividends or upon
liquidation, dissolution or winding up of the Company shall be treated as if
such security were Common Stock.

         ..  Dividends.  If the Company shall after the date of issuance of
this Warrant issue or distribute to all or substantially all holders of shares
of Common Stock evidences of indebtedness, any other securities of the Company
or any property, assets or cash, and if such issuance or distribution does not
constitute a Common Stock Reorganization or a Common Stock Distribution (any
such nonexcluded event being herein called a "Dividend"), (i) the number of
shares of Common Stock subject to purchase upon exercise of this Warrant shall
be increased (but not decreased), effective immediately after the record date
at which the holders of shares of Common Stock are determined for purposes of
such Dividend, to a number determined by multiplying the number of shares of
Common Stock subject to purchase immediately before such Dividend by a
fraction, the numerator of which shall be the Fair Market Value per share of
outstanding Common Stock on such record date and the denominator of which shall
be the Fair Market Value per share of outstanding Common Stock of the Company
on such record date less the then Fair Market Value of the evidences of
indebtedness, securities, cash, or property or other assets issued or
distributed in such Dividend with respect to one share of Common Stock, and
(ii) the Exercise Price shall be decreased (but not increased) to a price
determined by multiplying the Exercise Price then in effect by a fraction, the
numerator of which shall be the number of shares of Common Stock subject to

______________________________________


purchase upon exercise of this Warrant immediately before such Dividend and the
denominator of which shall be the number of shares of Common Stock subject to
purchase upon exercise of this Warrant immediately after such Dividend.  If
after the date of issuance of this Warrant the Company repurchases shares of
Common Stock for a per share consideration which exceeds the Fair Market Value
(as calculated immediately prior to such repurchase), then the number of shares
of Common Stock purchasable upon exercise of this Warrant and the Exercise
Price shall be adjusted in accordance with the foregoing provisions, as if, in
lieu of such repurchases, the Company had (I) distributed a Dividend having a
Fair Market Value equal to the Fair Market Value of all property and cash
expended in the repurchases, and (II) effected a reverse split of the Common
Stock in the proportion required to reduce the number of shares of Common Stock
outstanding from (A) the number of such shares outstanding immediately before
such first repurchase to (B) the number of such shares outstanding immediately
following all the repurchases.

         ..  Capital Reorganization.  If after the date of issuance of this
Warrant there shall be any consolidation or merger to which the Company is a
party, other than a consolidation or a merger in which the Company is a
continuing corporation and which does not result in any reclassification of, or
change (other than a Common Stock Reorganization or a change in par value) in,
outstanding shares of Common Stock, or any sale or conveyance of the property
of the Company as an entirety or substantially as an entirety (any such event
being called a "Capital Reorganization"), then, effective upon the effective
date of such Capital Reorganization, the Holder shall have the right to
purchase, upon exercise of this Warrant, the kind and amount of shares of stock
and other securities and property (including cash) which the Holder would have
owned or have been entitled to receive after such Capital Reorganization if
this Warrant had been exercised immediately prior to such Capital
Reorganization, assuming such holder (i) is not a person with which the Company
consolidated or into which the Company merged or which merged into the Company
or to which such sale or conveyance was made, as the case may be ("constituent
person"), or an Affiliate of a constituent person and (ii) failed to exercise
his rights of election, if any, as to the kind or amount  of securities, cash
or other property receivable upon such Capital Reorganization (provided that if
the kind or amount of securities, cash or other property receivable upon such
Capital Reorganization is not the same for each share of Common Stock held
immediately prior to such consolidation, merger, sale or conveyance by other
than a

constituent person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised ("non-electing share"), then for the
purposes of this Section the kind and amount of shares of stock and other
securities or other property (including cash) receivable upon such Capital
Reorganization shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares).  As a condition to effecting
any Capital Reorganization, the Company or the successor or surviving
corporation, as the case may be, shall execute and deliver to each
Warrantholder and to the Warrant Agency an agreement as to the Warrantholder's
rights in accordance with this Section 4.5, providing for subsequent
adjustments as nearly equivalent as may be practicable to the adjustments
provided for in this Article IV.  The provisions of this Section 4.5 shall
similarly apply to successive Capital Reorganizations.

         ..  Certain Other Events.  If any event occurs after the date of
issuance of this Warrant as to which the foregoing provisions of this Article
IV are not strictly applicable or, if strictly applicable, would not, in the
good faith judgment of the Board of Directors of the Company, fairly protect
the purchase rights of the Warrants in accordance with the essential intent and
principles of such provisions, then such Board shall make such adjustments in
the application of such provisions, in accordance with such essential intent
and principles, as shall be reasonably necessary, in the good faith opinion of
such Board, to protect such purchase rights as aforesaid, but in no event shall
any such adjustment have the effect of increasing the Exercise Price or
decreasing the number of shares of Common Stock subject to purchase upon
exercise of this Warrant, or otherwise adversely affect the Warrantholders.

         ..  Adjustment Rules.  ()      Any adjustments pursuant to this
Article IV shall be made successively whenever an event referred to herein
shall occur.

         ()    If the Company shall set a record date to determine the holders
of shares of Common Stock for purposes of a Common Stock Reorganization, Common
Stock Distribution, Dividend or Capital Reorganization, and shall legally
abandon such action prior to effecting such Action, then no adjustment

shall be made pursuant to this Article IV in respect of such action.

         ()    No adjustment in the amount of shares purchasable upon exercise
of this Warrant or in the Exercise Price shall be made hereunder unless such
adjustment increases or decreases such amount or price by one percent or more,
but any such lesser adjustment shall be carried forward and shall be made at
the time and together with the next subsequent adjustment which together with
any adjustments so carried forward shall serve to adjust such amount or price
by one percent or more.

         ()    No adjustment in the Exercise Price shall be made hereunder if
such adjustment would reduce the exercise price to an amount below par value of
the Common Stock, which par value shall initially be $0.01 per share of Common
Stock.

         ()    No adjustment shall be made pursuant to this Article IV in
respect of (i) the issuance (or deemed issuance) or repurchase of shares of
Common Stock in connection with the exercise of the Warrants or (ii) the
issuance of shares of Common Stock in an underwritten public offering managed
by a nationally recognized investment banking firm.

         ..  Proceedings Prior to Any Action Requiring Adjustment.  As a
condition precedent to the taking of any action which would require an
adjustment pursuant to this Article IV, the Company shall take any action which
may be necessary, including obtaining regulatory approvals or exemptions, in
order that the Company may thereafter validly and legally issue as fully paid
and nonassessable all shares of Common Stock which the holders of Warrants are
entitled to receive upon exercise thereof.

         ..  Notice of Adjustment.  Not less than 30 nor more than 40 days
prior to the record date or effective date, as the case may be, of any action
which requires or might require an adjustment or readjustment pursuant to this
Article IV, the Company shall give notice to each Warrantholder of such event,
describing such event in reasonable detail and specifying the record date or
effective date, as the case may be, and, if determinable, the required
adjustment and the

______________________________________


computation thereof.  If the required adjustment is not determinable at the
time of such notice, the Company shall give notice to each Warrantholder of
such adjustment and computation promptly after such adjustment becomes
determinable.  If no Holder objects to  any such notice within 30 days of
receipt of the Company's notice, the adjustment will be deemed accepted by the
Holders.

                                    ARTICLE

                                  DEFINITIONS

         The following terms, as used in this Warrant, have the following
respective meanings:

         "Appraisal Procedure" means a procedure whereby two independent
appraisers, one chosen by the Company and one by the Requisite Holders, shall
mutually agree upon the determinations then the subject of appraisal.  Each
party shall deliver a notice to the other appointing its appraiser within 15
days after the Appraisal Procedure is invoked.  If within 30 days after
appointment of the two appraisers they are unable to agree upon the amount in
question, a third independent appraiser shall be chosen within 10 days
thereafter by the mutual consent of such first two appraisers or, if such first
two appraisers fail to agree upon the appointment of a third appraiser, such
appointment shall be made by the American Arbitration Association, or any
organization successor thereto, from a panel of arbitrators having experience
in the appraisal of the subject matter to be appraised.  The decision of the
third appraiser so appointed and chosen shall be given within 30 days after the
selection of such third appraiser.  If three appraisers shall be appointed and
the determination of one appraiser is disparate from the middle determination
by more than twice the amount by which the other determination is disparate
from the middle determination, then the determination of such appraiser shall
be excluded, the remaining two determinations shall be averaged and such
average shall be binding and conclusive on the Company and the Warrantholders;





______________________________________

<PAGE>   173

______________________________________


otherwise the average of all three determinations shall be binding and
conclusive on the Company and the Warrantholders.  The costs of conducting any
Appraisal Procedure shall be borne by the Warrantholders requesting such
Appraisal Procedure, except (a) the fees and expenses of the appraiser
appointed by the Company and any costs incurred by the Company shall be borne
by the Company, (b) the fees and expenses of the appraiser appointed by the
Requisite Holders shall be borne by the Requisite Holders, and (c) the fees and
expenses of any third appraiser shall be shared equally by the Company and such
Requisite Holders; provided if such Appraisal Procedure shall result in a
determination that is disparate by 5% or more to the benefit of the holder from
the Company's initial  determination, all costs of conducting such Appraisal
Procedure shall be borne by the Company.

         "Business Day" shall mean (a) if any class of Common Stock is listed
or admitted to trading on a national securities exchange, a day on which the
principal national securities exchange on which such class of Common Stock is
listed or admitted to trading is open for business or (b) if no class of Common
Stock is so listed or admitted to trading, a day on which any New York Stock
Exchange member firm is open for business.

         "Capital Reorganization" shall have the meaning set forth in Section
4.5.

         "Closing Price" with respect to any security on any day means (a) if
such security is listed or admitted for trading on a national securities
exchange, the reported last sales price regular way or, if no such reported
sale occurs on such day, the closing bid price regular way on such day, in each
case as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which such class of security is listed or admitted to trading, or (b) if
such security is not listed or admitted to trading on any national securities
exchange, the last quoted sales price, or, if not so quoted, the closing bid
price in the over-the-counter market on such day as reported by NASDAQ or any
comparable system then in use or, if not so reported, as reported by any New
York Stock Exchange member firm reasonably selected by the Company for such
purpose.

and prior to the expiration of 20 Business Days after the ex-dividend date  for
such dividend or distribution, or the record date for such subdivision,

No. 1                                             4,500 Bond Appreciation Rights


         This certifies that FOR VALUE RECEIVED INDOSUEZ CM II, INC. or,
subject to the terms hereof, permitted transferees (the "Registered Holder"),
is the registered owner of the number of Bond Appreciation Rights ("BARs")
specified above.  Each BAR represents the equivalent of $1,000 face amount (the
"Equivalent Amount") of Senior Discount Notes due 2004 (the "Notes") of
American Telecasting, Inc., a Delaware corporation (the "Company"), and has an
initial value of $290 (the "BAR Price").  The Equivalent Amount and the BAR
Price are each subject to adjustment as provided in Section 5 hereof.  Upon the
presentation and surrender of this BAR Certificate, with the Exercise Form
attached hereto or a comparable form reasonably acceptable to the Company, duly
completed and executed, at the office of the Company during normal business
hours on any business day the Registered Holder shall be entitled to the
receipt of an amount calculated in the manner set forth in Section 2 hereof.

         This BARs Certificate shall be governed by and construed in accordance
with the internal laws of the State of New York (other than its rules of
conflicts of laws to the extent the application of the laws of another
jurisdiction would be required thereby).

    Procedures for Exercise of BARs.

         During the Exercise Period, a Registered Holder may exercise BARs by
surrendering a BARs Certificate or Certificates together with an Exercise Form
in the form attached hereto.  A BAR shall be deemed to be exercised at the time
immediately prior to the close of business on the business day (the "Exercise
Date") on which the duly executed and completed Exercise Form is received by
the Company at its office at 5575 Tech Center Drive, Suite 300, Colorado
Springs, CO 80919.

<PAGE>   186

                                      -3-

         The term "Exercise Period" shall mean the period beginning at the
earlier of (a) any event of default under the existing terms of the Notes or
(b) 9:00 a.m., New York City time, on June 15, 1999 and ending at 5:00 p.m.,
New York City time, on December 31, 2004.

         This BARs Certificate, upon the surrender hereof (in the manner
described above) by the Registered Holder, may be exchanged without charge for
one or more replacement BARs Certificates of like tenor and date entitling the
Registered Holder to the same aggregate number of BARs as is evidenced by this
surrendered BARs Certificate.

         The BARs represented hereby shall cease to be exercisable upon the
termination of the Exercise Period or earlier upon proper exercise.

    Payment of BAR Value.

         As soon as practicable after each exercise of a BAR, the Company will
pay to the Registered Holder in cash an amount (the "BAR Value") equal to the
excess of (A) the then current Market Price (as defined below) of the
Equivalent Amount as to which the BAR has been exercised over (B) the BAR Price
of the Equivalent Amount.

         "Market Price" of any security on any day means (i) the average bid
prices of three dealers who make a market in the security, which such dealers
shall be selected by a majority in interest of the Registered Holders, or (ii)
if such quotes are not so available or reported as determined by a majority in
interest of the Registered Holders and noticed to the Company, the fair
saleable value (the "Appraised Value") of such security (determined without
giving effect to any discount for (i) a minority interest or (ii) any lack of
liquidity) on such date, as determined in good faith by the Company's Board of
Directors, or if a majority in interest of the Registered Holders elect to
dispute such Appraised Value, the fair market value as determined in accordance
with the terms of Section 3(b).

    Determination and Payment of BAR Value.

<PAGE>   187

                                      -4-

         Determination and Payment.  Except as set forth in Section 3(b), the
BAR Value with respect to any exercise of BARs hereunder shall be determined
within 5 days of the Exercise Date and, subject to Section 4, shall be payable
in the manner provided below within one business day following the date of such
determination.  Payment of the BAR Value shall be made by wire transfer of
immediately available (same day) funds to an account in a bank located in the
United States designated by the Holder for such purpose.

         Appraisal.  If in determining the BAR Value it is necessary to
determine the Appraised Value of the Notes or other securities and a majority
in interest of the Registered Holders elects to dispute the determination made
by the Company, the Appraised Value shall be determined by two independent
appraisers, one chosen by the Company and one by a majority in interest of the
Registered Holders.  If within 20 days after appointment of the two appraisers
they are unable to agree upon the amount in question, a third independent
appraiser shall be chosen within 10 days thereafter by the mutual consent of
such first two appraisers or, if such first two appraisers fail to agree upon
the appointment of a third appraiser, such appointment shall be made by the
American Arbitration Association, or any organization successor thereto, from a
panel of arbitrators having experience in the appraisal of the subject matter
to be appraised.  The decision of the third appraiser so appointed and chosen
shall be given within 30 days after the selection of such third appraiser.  If
three appraisers shall be appointed and the determination of one appraiser is
disparate from the middle determination by more than twice the amount by which
the other determination is disparate from the middle determination, then the
determination of such appraiser shall be excluded, the remaining two
determinations shall be averaged and such average shall be binding and
conclusive on the Company and the Registered Holders; otherwise the average of
all three determinations shall be binding and conclusive on the Company and the
Registered Holders.  The costs of conducting any appraisal shall be borne as
follows:  (a) the fees and expenses of the appraiser appointed by the Company
and any costs incurred by the Company shall be borne by the Company,  (b) the
fees and expenses of the appraiser appointed by the Registered Holders and any
costs incurred by the Registered Holders shall be borne by the Registered
Holders and (c) the fees and expenses of any third appraiser shall be shared
equally by the Company and the Registered Holders electing such appraisal;
provided if such Appraised Value shall result in a determination that is
disparate by 5% or more from the Company's initial

<PAGE>   188

                                      -5-

determination, all costs of conducting such appraisal procedure shall be borne
by the Company.

    Non-Cash Payment Upon Exercise.

         Right to Pay in Other Securities.  Notwithstanding anything to the
contrary set forth in this Agreement, if on the date of exercise of any of the
BARs hereunder, the Company shall be prohibited from paying cash by the terms
of any loan or other agreement by which it is bound, the Registered Holder may
elect to receive, in lieu of all or a part of the BAR Value otherwise payable
in cash in respect of such exercise, (i) if permitted by the terms of the
Company's then existing agreements, Notes having an aggregate current Market
Value on the Exercise Date with respect to such exercise equal to such BAR
Value or (ii) if permitted by the terms of the Company's then existing
agreements, debt securities substantially similar to the Notes, in a form
mutually acceptable to the Company and the Registered Holder, having an
aggregate current Market Value on the Exercise Date with respect to such
exercise equal to such BAR Value.

         Prohibition on Payment.  The Company is not a party to any agreement
which would restrict the Company's ability to pay the BAR Value in cash.  The
Company agrees that it will not, without the consent of the Registered Holders
of a majority of the BARs at the time then outstanding, enter into any
agreement or amend any existing agreement which would prohibit or otherwise
limit the Company's ability to make cash payments or payments in the form of
Notes or other securities upon exercise of the BARs.

    Adjustments.

         Adjustment or Substitution of Notes and Price.  In the event that the
Notes are changed into or exchanged for a different kind or number of debt
securities, or equity or other securities (including warrants or rights to
acquire stock or securities) or assets (including cash) of the Company or stock
or securities or assets (including cash) of another corporation, then an
appropriate and equitable adjustment shall be made in the number and kind of
securities or other assets the Market Value of which determines the BAR Value
payable in respect of exercises of any BARs hereunder, and/or in the kind of

<PAGE>   189

                                      -6-

securities deliverable under Section 4, so as to prevent the dilution of rights
represented by the BARs granted hereunder.  In the event of a transaction
(including a tender or exchange offer) in which the Notes are changed into or
exchanged for shares of stock or securities of another corporation, that other
corporation shall expressly assume the due and punctual observance and
performance of each and every covenant and condition of this Agreement to be
performed and observed by the Company and all the obligations and liabilities
hereunder, subject to such modifications as may be deemed appropriate (as
determined in good faith by resolution of the Board of Directors of the
Company) in order to provide for adjustments which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 5(a).
In the event that the Company shall make any direct or indirect payment or
distribution to more than 50% of the holders of Notes, other than payments of
interest, the BAR Price shall be adjusted downward to reflect fully any such
payment or distribution.  The foregoing provisions of this Section 5(a) shall
similarly apply to successive reorganizations, tender offers, exchange offers
and other transactions.

         Notice of Adjustments.  Whenever an adjustment is made pursuant to
Section 5(a), the Company shall promptly prepare a certificate to be executed
by the chief financial officer of the Company setting forth, in reasonable
detail, the event requiring the adjustment and the method by which such
adjustment was calculated, specifying the number and kind of securities or
other assets the current Market Value of which determines the BAR Value payable
in respect of exercises of BARs hereunder and/or the kind of securities
deliverable under Section 4, as the case may be, after giving effect to such
adjustment or change.  The Company shall promptly cause a signed copy of such
certificate to be delivered to each Holder.  The Company shall keep at its
office copies of all such certificates and cause the same to be available for
inspection at said office during normal business hours by any Holder.

         Notice of Other Corporate Actions.  The Company shall promptly give
notice to each Holder of any other corporate action for which notice is given
to holders of Notes of the Company.

    Assignability.

<PAGE>   190

                                      -7-

         This BARs Certificate shall be transferable, in whole or in part, upon
surrender of this BARs Certificate to the Company, together with a written
assignment of the BARs certificate, on the Form of Assignment attached hereto
or in other form reasonably satisfactory to the Company, duly executed by the
Registered Holder hereof or his duly appointed legal representative.  If less
than all of the BARs Certificate is being transferred, a new BARs Certificate
or BARs Certificates shall be issued to the Registered Holder for the portion
of the BARs Certificate not being transferred.

    Expenses.

         The Company shall promptly reimburse the Registered Holders for all
reasonable fees (including reasonable attorney fees and expenses) incurred by
such Registered Holder in connection with the enforcement of its rights
hereunder.

    Severability of Provisions.

         Whenever possible, each provision hereof shall be interpreted in a
manner as to be effective and valid under applicable law, but if any provision
hereof is held to be prohibited by or invalid under applicable law, such
provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating or otherwise adversely affecting the remaining
provisions hereof.  If a court of competent jurisdiction should determine that
a provision hereof would be valid or enforceable if a period of time were
extended or shortened or a particular percentage were increased or decreased,
then such court may make such change as shall be necessary to render the
provision in question effective and valid under applicable law.

    Governing Law.

         This Agreement shall be construed in accordance with and governed by
the laws of the State of New York without regard to principles of conflicts of
law.

    Headings.

<PAGE>   191

                                      -8-

         The headings of the paragraphs in this BARs Certificate are for
convenience of reference only and shall not define, limit or affect any of the
provisions hereof.

    Replacement of BARs.

         Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction or mutilation of any BARs Certificate and

         in the case of any such loss, theft or destruction of any BARs
    Certificate, upon delivery of indemnity reasonably satisfactory to the
    Company, or

         in the case of any such mutilation, upon surrender of such BARs
    Certificate for cancellation at the principal office of the Company,

the Company at its expense will execute and deliver, in lieu thereof, a new
BARs Certificate of like tenor.

    No Rights or Liabilities as Stockholder.

         Nothing contained in this BARs Certificate shall be construed as
conferring upon the Registered Holder hereof any rights as a stockholder of the
Company, or as imposing any liabilities on such Holder as a stockholder of the
Company or, to purchase any securities of the Company, whether such liabilities
are asserted by the Company or by creditors or stockholders of the Company or
by any other person.

         IN WITNESS WHEREOF, the Company has caused this BARs Certificate to be
duly exercised, manually or in facsimile, by two of its officers thereunto duly
authorized.

                                                                CREDIT AGREEMENT

                          SECURITIES PLEDGE AGREEMENT

          This SECURITIES PLEDGE AGREEMENT (the "Agreement"), dated as of
February 26, 1997, made by AMERICAN TELECASTING, INC., a Delaware corporation
having an office at 5575 Tech Center Drive, Suite 300, Colorado Springs, CO
80919 (the "Pledgor"), in favor of BANQUE INDOSUEZ, NEW YORK BRANCH, having an
office at 1211 Avenue of the Americas, New York, New York 10036, as pledgee,
assignee and secured party, in its capacity as collateral agent (in such
capacities and together with any successors in such capacities, the "Collateral
Agent") for the lending institutions (the "Banks") under the Credit Agreement
(as hereinafter defined).

                               R E C I T A L S :

          Pursuant to a certain credit agreement, dated as of the date hereof
(as amended, amended and restated, supplemented or otherwise modified from time
to time, the "Credit Agreement"; unless otherwise defined herein, capitalized
terms used herein have the meanings assigned to them in the Credit Agreement),
among the Pledgor, the Banks and Banque Indosuez, New York Branch, as Agent for
the Banks, the Banks have agreed to make to or for the account of the Pledgor
certain Loans up to an aggregate principal amount of $17,000,000.

         The Pledgor is the legal and beneficial owner of the Pledged
Collateral (as hereinafter defined) pledged by it.

         It is a condition precedent to the obligations of the Banks to make
the Loans under the Credit Agreement that the Pledgor execute and deliver the
applicable Credit Documents, including this Agreement.

         This Agreement is given by the Pledgor in favor of Collateral Agent
for its benefit and the benefit of the Banks and the Agent (collectively, the
"Secured Parties") to secure the payment and performance of all of the Secured
Obligations (as defined in Section 2).
<PAGE>   197
                              A G R E E M E N T :

          NOW, THEREFORE, in consideration of the foregoing premises and other
good and valuable consideration, the receipt   and sufficiency of which are
hereby acknowledged, the Pledgor and Collateral Agent hereby agree as follows:

          Pledge.  As collateral security for the payment and performance when
due of all the Secured Obligations, the Pledgor hereby pledges, assigns,
transfers and grants to Collateral Agent for the benefit of the Secured
Parties, a continuing first priority security interest in and to all of the
right, title and interest of the Pledgor in and to the following property,
whether now existing or hereafter acquired, (collectively, the "Pledged
Collateral"):

         the issued and outstanding shares of capital stock described on
    Schedule I hereto ("the Pledged Shares"), including the certificates
    representing the Pledged Shares and any interest of the Pledgor in the
    entries on the books of any financial intermediary pertaining to the
    Pledged Shares;

         all additional shares of capital stock of any issuer of the Pledged
    Shares from time to time acquired by the Pledgor in any manner (which
    securities shall be deemed to be part of the Pledged Shares) and the
    certificates representing such additional securities and any interest of
    the Pledgor in the entries on the books of any financial intermediary
    pertaining to such additional securities;

         all intercompany notes described on Schedule II hereto (the
    "Intercompany Notes") now owned or held by Pledgor and from time to time
    acquired by Pledgor in any way, and all certificates or instruments
    evidencing such Intercompany Notes and all proceeds thereof, all accessions
    thereto and substitutions therefor;

         all dividends, cash, options, warrants, rights, instruments,
    distributions, returns of capital, income, profits and other property,
    interests or proceeds from time to time received, receivable or otherwise
    distributed to the Pledgor in respect of or in exchange for any or all of
    the Pledged Shares (collectively, "Distributions"); and
<PAGE>   198
         all Proceeds (as defined under the Uniform Commercial Code as in
    effect in any relevant jurisdiction (the "UCC") or under other relevant
    law) of any of the foregoing, and in any event, including, without
    limitation, any and all (i) proceeds of any insurance (except  payments
    made to a Person which is not a party to this Agreement), indemnity,
    warranty or guarantee payable to Collateral Agent or to the Pledgor from
    time to time with respect to any of its respective Pledged Collateral, (ii)
    payments (in any form whatsoever) made or due and payable to the Pledgor
    from time to time in connection with any requisition, confiscation,
    condemnation, seizure or forfeiture of all or any part of its respective
    Pledged Collateral by any Governmental Authority (or any person acting
    under color of a Governmental Authority), (iii) instruments representing
    obligations to pay amounts in respect of Pledged Shares, (iv) products of
    the Pledged Collateral and (v) other amounts from time to time paid or
    payable under or in connection with any of the Pledged Collateral.

         Secured Obligations.  This Agreement secures, and the Pledged
Collateral is collateral security for, the payment and performance in full when
due, whether at stated maturity, by acceleration or otherwise (including,
without limitation, the payment of interest and other amounts which would
accrue and become due but for the filing of a petition in bankruptcy or the
operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11
U.S.C. Section 362(a)) of (i) all Obligations of the Pledgor now existing or
hereafter arising under or in respect of the Credit Agreement (including,
without limitation, the obligations of the Pledgor to pay principal, interest
and all other reasonable charges, fees, expenses, commissions, reimbursements,
premiums, indemnities and other payments related to or in respect of the
Obligations contained in the Credit Agreement), and (ii) without duplication of
the amounts described in clause (i), all Obligations of the Pledgor now
existing or hereafter arising under or in respect of this Agreement or any
other Security Document, including, without limitation, with respect to all
reasonable charges, fees, expenses, commissions, reimbursements, premiums,
indemnities and other payments related to or in respect of the obligations
contained in this Agreement (the obligations described in clauses (i) and (ii),
collectively, the "Secured Obligations").

          No Release.  Subject to Section 18 of this Agreement, nothing set
forth in this Agreement shall relieve the Pledgor from the performance of any
term, covenant, condition on the Pledgor's part to be performed or observed
<PAGE>   199
under or in respect of any of the Pledged Collateral or from any liability to
the Person under or in respect of any of the  Pledged Collateral or shall
impose any obligation on Collateral Agent or any Secured Party to perform or
observe any such term, covenant, condition or agreement on the Pledgor's part
to be so performed or observed or shall impose any liability on Collateral
Agent or any Secured Party for any act or omission on the part of the Pledgor
relating thereto or for any breach of any representation or warranty on the
part of the Pledgor contained in this Agreement, or any other Credit Document
or under or in respect of the Pledged Collateral or made in connection herewith
or therewith.  Subject to Section 18 of this Agreement, the obligations of the
Pledgor contained in this Section 3 shall survive the termination of this
Agreement and the discharge of the Pledgors' other obligations under this
Agreement and the other Credit Documents.

          Delivery of Pledged Collateral.

          All certificates, agreements or instruments representing or
evidencing the Pledged Collateral, to the extent not previously delivered to
Collateral Agent, shall immediately upon receipt thereof by the Pledgor be
delivered to and held by or on behalf of Collateral Agent pursuant hereto.  All
Pledged Collateral shall be in suitable form for transfer by delivery or shall
be accompanied by duly executed instruments of transfer or assignment in blank
(with signatures appropriately guaranteed), all in form and substance
satisfactory to Collateral Agent.  Subject to the provisions of Section 29 of
this Agreement, Collateral Agent shall have the right, at any time upon the
occurrence and during the continuance of an Event of Default, to endorse,
assign or otherwise transfer to or to register in the name of Collateral Agent
or any of its nominees any or all of the Pledged Collateral.  Collateral Agent
shall provide the Pledgor with notice of any endorsement, assignment or other
transfer made pursuant to the preceding sentence.  In addition, upon the
occurrence and during the continuance of an Event of Default, Collateral Agent
shall have the right at any time to exchange certificates representing or
evidencing Pledged Collateral for certificates of smaller or larger
denominations.

          If an issuer of Pledged Shares is incorporated in a jurisdiction
which does not permit the use of certificates to evidence equity ownership,
then the Pledgor shall, to the extent permitted by applicable law, record such
pledge on the stock register of such issuer, execute any customary stock pledge
forms or other documents necessary or appropriate to complete the pledge and
give Collateral Agent the right to
<PAGE>   200
transfer the Pledged Shares under the terms hereof and provide to Collateral
Agent an opinion of counsel, in form and substance satisfactory to Collateral
Agent, confirming such pledge.

          Notwithstanding any provision of this Section 4 to the contrary, if
the exercise of any rights provided in this Section 4 or Section 10 relates to
the ownership or control of any radio, television or other license, permit,
certificate or approval granted or issued by the FCC or any other Governmental
Authority (including, without limitation, any multichannel or single channel
multipoint distribution service, local multipoint distribution service,
operational- fixed microwave service, cable television relay service station,
business radio, instructional television fixed service, earth station or
experimental licenses or permits issued by the FCC) (each, a "Governmental
License") held by the Pledgor or a subsidiary of the Pledgor and it may be
necessary to obtain the consent or approval of the FCC prior to the exercise of
such rights, the provisions of Section 29 of this Agreement shall apply.

          Supplements, Further Assurances.

          The Pledgor agrees that at any time and from time to time, at the
sole cost and expense of such Pledgor, the Pledgor shall promptly execute and
deliver all further instruments and documents, including, without limitation,
supplemental or additional UCC-1 financing statements, and take all further
action that may be necessary or that Collateral Agent may reasonably request,
in order to perfect and protect the pledge, security interest and Lien granted
or purported to be granted hereby or to enable Collateral Agent to exercise and
enforce its rights and remedies hereunder with respect to any Pledged
Collateral.

          The Pledgor shall, upon obtaining any Pledged Shares of any Person
promptly (and in any event within three Business Days) deliver to Collateral
Agent a pledge amendment, duly executed by the Pledgor, in substantially the
form of Exhibit 1 hereto (the "Pledge Amendment"), in respect of the additional
Pledged Shares which are to be pledged pursuant to this Agreement, and
confirming the attachment of the Lien hereby created on and in respect of such
Pledged Collateral.  The Pledgor hereby authorizes Collateral Agent to attach
each Pledge Amendment to this Agreement and agrees that all Pledged Shares
listed on any Pledge Amendment delivered to Collateral  Agent shall for all
purposes hereunder be considered Pledged Collateral.
<PAGE>   201
     Representations, Warranties and Covenants.  The Pledgor represents,
warrants and covenants as follows (as to itself only):

         No Liens.  The Pledgor is, and at the time of any delivery of any
    Pledged Collateral to Collateral Agent pursuant to Section 4 of this
    Agreement will be, the sole legal and beneficial owner of the Pledged
    Collateral pledged by it pursuant to this Agreement.  All Pledged
    Collateral is on the date hereof, and will be be, so owned by the Pledgor,
    as applicable, free and clear of any Lien except for the Lien created by
    this Agreement.

         Authorization, Enforceability.  The Pledgor has the requisite
    corporate power, authority and legal right to pledge and grant a security
    interest in all of the Pledged Collateral pledged by it pursuant to this
    Agreement, and this Agreement constitutes the legal, valid and binding
    obligation of the Pledgor, enforceable against the Pledgor in accordance
    with its terms.

         No Consents, etc.  No consent of any party (including, without
    limitation, any stockholders or creditors of the Pledgor) and no consent,
    authorization, approval, or other action by, and no notice to or filing
    with, any Governmental Authority or regulatory body or other Person is
    required either (x) for the pledge by the Pledgor of the Pledged Collateral
    pledged by it pursuant to this Agreement or for the execution, delivery or
    performance of this Agreement by the Pledgor, or (y) for the exercise by
    Collateral Agent of the voting or other rights provided for in this
    Agreement, or (z) for the exercise by Collateral Agent of the remedies in
    respect of the Pledged Collateral pursuant to this Agreement; provided,
    however, that under the Communications Act and the rules and regulations of
    the FCC, FCC consent may be required prior to the transfer of control or
    assignment of any Governmental License issued by the FCC, or the exercise
    of any voting rights or management over the Pledgor or an issuer of Pledged
    Shares to the extent it holds, owns or controls any Governmental License
    issued by the FCC.

    located at 5575 Tech Center Drive, Suite 300, Colorado Springs, Colorado
    80919.  Pledgor shall not move its chief executive office except to such
    new location as Pledgor may establish in accordance with the last sentence
    of this Section 6(e).  Pledgor shall not establish a new location for its
    chief executive office nor shall it change its name until (i) it shall have
    given Collateral Agent not less than 45 days' prior written notice of its
    intention so to do, clearly describing such new location or name and
    providing such other information in connection therewith as Collateral
    Agent or any Secured Party may request, and (ii) with respect to such new
    location or name, Pledgor shall have taken all action satisfactory to
    Collateral Agent and the Secured Parties to maintain the perfection and
    priority of the security interest of Collateral Agent for the benefit of
    the Secured Parties in the Pledged Collateral intended to be granted
    hereby.

         Delivery of Pledged Collateral; Filings.  The Pledgor has delivered to
    Collateral Agent all certificates representing the Pledged Shares and
    Intercompany Notes and has caused to be filed with the Secretary of State
    of the State of New York, the State of incorporation of the Pledgor and the
    State of Colorado, which is the State of the chief executive office of the
    Pledgor, UCC-1 financing statements evidencing the Lien created by this
    Agreement, and such delivery, filing and pledge of the Pledged Collateral
    pursuant to this Agreement creates a valid and perfected first priority
    security interest in the Pledged Collateral securing the payment of the
    Secured Obligations pursuant to the UCC, including, without limitation, the
    UCC as in effect in the States of New York, the State of incorporation of
    the Pledgor and the State of Colorado, which is the State of the chief
    executive office of the Pledgor.

         Pledged Collateral.  All information set forth herein, including the
    Schedules annexed hereto, and all information contained in any documents,
    schedules and lists heretofore delivered to any Secured Party in connection
    with this Agreement, in each case, relating to the  Pledged Collateral is
    accurate and complete in all respects.

         No Violations, etc.  The pledge of the Pledged Collateral pursuant to
    this Agreement does not violate Regulation G, T, U or X of the Federal
    Reserve Board.
<PAGE>   203
         Ownership of Pledged Collateral.  Except as otherwise permitted by the
    Credit Agreement, the Pledgor at all times will be the sole beneficial
    owner of the Pledged Collateral pledged by it pursuant to this Agreement.

         No Options, Warrants, etc.  Except as disclosed in the Credit
    Agreement, there are no options, warrants, calls, rights, commitments or
    agreements of any character to which the Pledgor is a party or by which it
    is bound obligating the Pledgor to issue, deliver or sell or cause to be
    issued, delivered or sold, additional securities of any issuer of the
    Pledged Shares or obligating any issuer of the Pledged Shares to grant,
    extend or enter into any such option, warrant, call, right, commitment or
    agreement.  There are no voting trusts or other agreements or
    understandings to which the Pledgor or any issuer of the Pledged Shares is
    a party with respect to the voting of the securities of any issuer of the
    Pledged Shares.

         Endorsement, Assignment or Pledge of Instruments.  None of the Pledged
    Collateral is, as of the date of this Agreement, and as to Pledged
    Collateral which arises from time to time after such date will be,
    evidenced by any instrument, note or chattel paper, except such as have
    been or will be endorsed, assigned or pledged and delivered to Collateral
    Agent by Pledgors simultaneously with the creation thereof.

         Systems.  The Pledged Shares include the Pledgor's interest in each
    Credit Party operating Systems or holding System Agreements.

         Voting Rights; Distributions; etc.

         So long as no Event of Default shall have occurred and be continuing:

         The Pledgor shall be entitled to exercise any and all voting and other
    consensual rights pertaining to  the Pledged Shares pledged by it pursuant
    to this Agreement or any part thereof for any purpose not inconsistent with
    the terms or purpose of this Agreement or any of the other Credit Documents
    and each Pledgor shall not in any event exercise such rights in any manner
    which may have an adverse effect on the value of
<PAGE>   204
    its respective Pledged Collateral or the security intended to be provided by
    this Agreement.

         Subject to the terms of the Credit Agreement, each Pledgor shall be
    entitled to receive and retain, and to utilize free and clear of the Lien
    of this Agreement, any and all Distributions, but only if and to the extent
    made in accordance with the provisions of the Credit Agreement; provided,
    however, that any and all such Distributions consisting of rights or
    interests in the form of securities shall be, and shall be forthwith
    delivered to Collateral Agent to hold as Pledged Collateral and shall, if
    received by the Pledgor, be received in trust for the benefit of Collateral
    Agent, be segregated from the other property or funds of such Pledgor, and
    be forthwith delivered to Collateral Agent as Pledged Collateral in the
    same form as so received (with any necessary endorsement).

         Collateral Agent shall be deemed without further action or formality
    to have granted to each Pledgor all necessary consents relating to voting
    rights and shall, if necessary, upon written request of the Pledgor and at
    such Pledgor's sole cost and expense, from time to time execute and deliver
    (or cause to be executed and delivered) to such Pledgor all such
    instruments as such Pledgor may reasonably request in order to permit such
    Pledgor to exercise the voting and other rights which it is entitled to
    exercise pursuant to Section 7(a)(i) hereof and to receive the
    Distributions which it is authorized to receive and retain pursuant to
    Section 7(a)(ii) hereof.

         Upon the occurrence and during the continuance of an Event of Default:

         All rights of the Pledgor to exercise the voting and other consensual
    rights it would otherwise be entitled to exercise pursuant to Section
    7(a)(i) hereof without any action or the giving of any notice shall cease,
    and all such rights shall thereupon become vested in Collateral Agent,
    which shall thereupon have the sole right to  exercise such voting and
    other consensual rights; provided, however, to the extent the Pledgor or an
    issuer of Pledged Shares hold, own or control any Governmental License
    issued by
<PAGE>   205
    the FCC, if and to the extent required under the Communications Act or the
    FCC's rules, until the FCC has consented to a transfer of control or
    assignment of Pledgor, an issuer of Pledged Shares, or such Governmental
    License issued by the FCC, Pledgor shall continue to exercise the voting
    and other consensual rights.

         All rights of the Pledgor to receive Distributions which it would
    otherwise be authorized to receive and retain pursuant to Section 7(a)(ii)
    hereof shall cease and all such rights shall thereupon become vested in
    Collateral Agent, which shall thereupon have the sole right to receive and
    hold as Pledged Collateral such Distributions.

         Subject to any necessary prior or subsequent FCC approval, Collateral
    Agent shall be entitled to the appointment, as a matter of right and
    without giving notice to the Pledgor, of a receiver with respect to the
    Pledged Collateral, without regard to the adequacy or inadequacy of any
    Pledged Collateral for the Secured Obligations or the solvency or
    insolvency of any person or entity then legally or equitably liable for the
    Secured Obligations or any portion thereof, and each Pledgor does hereby
    irrevocably consent to such appointment.  Any such receiver shall have all
    the usual qualifications, powers and duties of receivers in similar cases,
    including the full power to conduct the business of the Pledgors.

          The Pledgor shall, at such Pledgor's sole cost and expense, from time
to time execute and deliver to Collateral Agent and any other Person directed
by Collateral Agent, appropriate instruments as Collateral Agent may request in
order to permit Collateral Agent to exercise the voting and other rights which
it may be entitled to exercise pursuant to Section 7(b)(i) hereof and to
receive all Distributions which it may be entitled to receive under Section
7(b)(ii) hereof.

          All Distributions which are received by the Pledgor contrary to the
provisions of Section 7(b)(ii) hereof shall be received in trust for the
benefit of Collateral Agent, shall be segregated from other funds of such
Pledgor and shall immediately be paid over to Collateral Agent as Pledged
Collateral in the same form as so received (with any necessary endorsement).

          Transfers and Other Liens; Additional Shares; Principal Office.

          The Pledgor shall not (i) sell, convey, assign or otherwise dispose
of, or grant any option, right or warrant
<PAGE>   206
with respect to, any of the Pledged Collateral pledged by it pursuant to this
Agreement, (ii) create or permit to exist any Lien upon or with respect to any
Pledged Collateral pledged by it pursuant to this Agreement other than the Lien
granted to Collateral Agent under this Agreement, or (iii) permit any issuer of
the Pledged Shares to merge, consolidate or change its legal form unless a
majority of the outstanding capital stock of the surviving or resulting
corporation is, upon such merger or consolidation, pledged to Collateral Agent
pursuant to a pledge agreement in form and substance, satisfactory to
Collateral Agent, and no cash, securities or other property is distributed in
respect of the outstanding shares of any other constituent corporation.

          The Pledgor shall (i) cause each issuer of the Pledged Shares not to
issue any stock or other securities in addition to or in substitution for the
Pledged Shares issued by such issuer, except to such Pledgor and (ii) pledge
hereunder, immediately upon its acquisition (directly or indirectly) thereof,
any and all additional shares of capital stock or other equity securities of
any issuer of the Pledged Shares which are required to be pledged hereunder.

          Reasonable Care.  Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Pledged Collateral in
its possession if such Pledged Collateral is accorded treatment substantially
equivalent to that which Collateral Agent, in its individual capacity, accords
its own property consisting of similar instruments or interests, it being
understood that neither the Collateral Agent nor any of the Secured Parties
shall have responsibility for (i) ascertaining or taking action with respect to
calls, conversions, exchanges, maturities, tenders or other matters relating to
any Pledged Collateral, whether or not Collateral Agent or any other Secured
Party has or is deemed to have knowledge of such matters, or (ii) taking any
necessary steps to preserve rights against any Person with respect to any
Pledged Collateral.

          Remedies Upon Default; Decisions Relating to Exercise of Remedies.

          If any Event of Default shall have occurred and be continuing,
subject to the provisions of Section 29 of this Agreement, Collateral Agent
shall have the right, in addition to other rights and remedies provided for
herein or otherwise available to it to be exercised from time to time, (i) to
retain and apply the Distributions to the Secured Obligations as provided in
Section 11 hereof, and (ii) to exercise all the rights and remedies of a
secured party on default under
<PAGE>   207
the UCC, and Collateral Agent may also in its sole discretion, without notice
except as specified below, sell the Pledged Collateral or any part thereof
(including, without limitation, any partial interest in the Pledged Shares) in
one or more parcels at public or private sale, at any exchange, broker's board
or at any of Collateral Agent's offices or elsewhere, for cash, on credit or
for future delivery, and at such price or prices and upon such other terms as
Collateral Agent may deem commercially reasonable, irrespective of the impact
of any such sales on the market price of the Pledged Collateral.  Collateral
Agent or any other Secured Party or any of their respective Affiliates may be
the purchaser of any or all of the Pledged Collateral at any such sale and
shall be entitled, for the purpose of bidding and making settlement or payment
of the purchase price for all or any portion of the Pledged Collateral sold at
such sale, to use and apply any of the Secured Obligations owed to such Person
as a credit on account of the purchase price of any Pledged Collateral payable
by such Person at such sale.  Each purchaser at any such sale shall acquire the
property sold absolutely free from any claim or right on the part of the
Pledgor, and Pledgor hereby waives (to the fullest extent permitted by law) all
rights of redemption, stay and/or appraisal which it now has or may at any time
in the future have under any rule of law or statute now existing or hereafter
enacted.  The Pledgor acknowledges and agrees that, to the extent notice of
sale shall be required by law, five (5) days' notice to such Pledgor of the
time and place of any public sale or the time after which any private sale is
to be made shall constitute reasonable notification.  No notification need be
given to the Pledgor if it has signed, after the occurrence of an Event of
Default, a statement renouncing or modifying any right to notification of sale
or other intended disposition.  Collateral Agent shall not be obligated to make
any sale of Pledged Collateral regardless of notice of sale having been given.
Collateral Agent may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor,  and such sale may, without
further notice, be made at the time and place to which it was so adjourned.
The Pledgor hereby waives any claims against Collateral Agent arising by reason
of the fact that the price at which any Pledged Collateral may have been sold
at such a private sale was less than the price which might have been obtained
at a public sale, even if Collateral Agent accepts the first offer received and
does not offer such Pledged Collateral to more than one offeree.
Notwithstanding any provision of this subsection 10(a) to the contrary, in the
event of a private or public sale of the Pledged Collateral, prior to the
consummation of the sale, to the extent required under the Communications Act
of 1934, as amended, or any successor statute or law (the "Communications
Act"), the prior consent of the FCC pursuant to the
<PAGE>   208
Communications Act and the rules and regulations of the FCC will be obtained.

          The Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended (the "Securities Act"), and
applicable state securities laws, Collateral Agent may be compelled, with
respect to any sale of all or any part of the Pledged Collateral, to limit
purchasers to Persons who will agree, among other things, to acquire the
Pledged Collateral for their own account, for investment and not with a view to
the distribution or resale thereof.  The Pledgor acknowledges that any such
private sales may be at prices and on terms less favorable to Collateral Agent
than those obtainable through a public sale without such restrictions
(including, without limitation, a public offering made pursuant to a
registration statement under the Securities Act), and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner and that Collateral Agent shall have
no obligation to engage in public sales and no obligation to delay the sale of
any Pledged Collateral for the period of time necessary to permit the issuer
thereof to register it for a form of public sale requiring registration under
the Securities Act or under applicable state securities laws, even if such
issuer would agree to do so.

          Notwithstanding the foregoing and to the extent commercially
reasonable, each Pledgor shall, upon the occurrence and during the continuance
of an Event of Default, at the request of Collateral Agent, for the benefit of
Collateral Agent, cause any registration, qualification under or compliance
with any federal or state securities law or laws to be effected with respect to
all or any part of the Pledged  Collateral as soon as practicable and at such
Pledgor's sole cost and expense.  The Pledgor will use its best efforts to
cause such registration to be effected (and be kept effective) and will use its
best efforts to cause such qualification and compliance to be effected (and be
kept effective) as may be so requested and as would permit or facilitate the
sale and distribution of such Pledged Collateral, including, without
limitation, registration under the Securities Act (or any similar statute then
in effect), appropriate qualifications under applicable blue sky or other state
securities laws and appropriate compliance with any other government
requirements.  The Pledgor will cause Collateral Agent to be kept advised in
writing as to the progress of each such registration, qualification or
compliance and as to the completion thereof, will furnish to Collateral Agent
such number of prospectuses, offering circulars or other documents incident
thereto as Collateral Agent from time to time may request, and will indemnify
and
<PAGE>   209
will cause the issuer of the Pledged Collateral to indemnify Collateral Agent
and all others participating in the distribution of such Pledged Collateral
against all claims, losses, damages and liabilities caused by any untrue
statement (or alleged untrue statement) of a material fact contained therein
(or in any related registration statement, notification or the like) or by any
omission (or alleged omission) to state therein (or in any related registration
statement, notification or the like) a material fact required to be stated
therein or necessary to make the statements therein not misleading.

          If Collateral Agent determines to exercise its right to sell any or
all of the Pledged Collateral, upon written request, each Pledgor shall from
time to time furnish to Collateral Agent all such information as Collateral
Agent may request in order to determine the number of securities included in
the Pledged Collateral which may be sold by Collateral Agent as exempt
transactions under the Securities Act and the rules of the Securities and
Exchange Commission thereunder, as the same are from time to time in effect.

          The Pledgor recognizes, by reason of certain prohibitions contained
in laws, rules, regulations or orders of any foreign Governmental Authority,
Collateral Agent may be compelled, with respect to any sale of all or any part
of the Pledged Collateral, to limit purchasers to those who meet the
requirements of such foreign Governmental Authority.  The Pledgor acknowledges
that any such sales may be at prices and on terms less favorable to Collateral
Agent than those obtainable through a public sale without such restrictions,
and, notwithstanding such circumstances, agrees that any such restricted sale
shall be deemed to have been made in a commercially reasonable manner and that
Collateral Agent shall have no obligation to engage in public sales.

          In addition to any of the other rights and remedies hereunder,
Collateral Agent shall have the right to institute a proceeding seeking
specific performance in connection with any of the agreements or obligations
hereunder.

          Without limiting the generality of the provisions in Section 15
hereof, Pledgor hereby constitutes and appoints Collateral Agent, with full
power of substitution, its true and lawful attorney-in-fact, in its name, place
and stead to take any action upon the occurrence and during the continuance of
an Event of Default required to reflect the foreclosure sale of the Pledged
Collateral or the exercise of any remedy hereunder.  The foregoing grant of
authority is a power of attorney coupled with an interest and such
<PAGE>   210
appointment shall be irrevocable for the term of this Agreement.

          Application of Proceeds.  All Distributions held from time to time by
Collateral Agent and all cash proceeds received by Collateral Agent in respect
of any sale of, collection from, or other realization upon all or any part of
the Pledged Collateral pursuant to the exercise by Collateral Agent of its
remedies as a secured creditor as provided in Section 10 hereof shall be
applied, together with any other sums then held by Collateral Agent pursuant to
this Agreement, promptly by Collateral Agent as follows:

         First, to the payment of all reasonable costs and expenses, fees,
    commissions and taxes of such sale, collection or other realization,
    including, without limitation, reasonable compensation to Collateral Agent
    and its agents and counsel, and all reasonable expenses, liabilities and
    advances made or incurred by Collateral Agent in connection therewith,
    together with interest on each such amount at the highest rate then in
    effect under the Credit Agreement from and after the date such amount is
    due, owing or unpaid until paid in full;

         Second, to the payment of all other reasonable costs and expenses of
    such sale, collection or other realization, including, without limitation,
    reasonable compensation to the Banks and their agents and counsel and all
    reasonable expenses, liabilities and advances made or  incurred by the
    Banks in connection therewith, together with interest on each such amount
    at the highest rate then in effect under the Credit Agreement from and
    after the date such amount is due, owing or unpaid until paid in full;

         Third, to the indefeasible payment in full in cash of interest and all
    amounts other than principal under the Credit Agreement at any time and
    from time to time owing by the Pledgor under or in connection with the
    Credit Agreement, ratably according to the unpaid amounts thereof, without
    preference or priority of any kind among amounts so due and payable,
    together with interest on each such amount at the highest rate then in
    effect under the Credit Agreement from and after the date such amount is
    due, owing or unpaid until paid in full;

         Fourth, to the indefeasible payment in full in cash of principal at
    any time and from time to time owing by
<PAGE>   211
    the Pledgor under or in connection with the Credit Agreement, ratably
    according to the unpaid amounts thereof, without preference or priority of
    any kind, among amounts of principal so due and payable, together with
    interest on each such amount at the highest rate then in effect under the
    Credit Agreement from and after the date such amount is due, owing or
    unpaid until paid in full; and

         Fifth, to the applicable Pledgor, or its successors or assigns or to
    whomsoever may be lawfully entitled to receive the same or as a court of
    competent jurisdiction may direct, of any surplus then remaining from such
    proceeds.

          Expenses.  The Pledgor will upon demand pay to Collateral Agent the
amount of any and all expenses, including the reasonable fees and expenses of
its counsel and the fees and expenses of any experts and agents, which
Collateral Agent may incur in connection with (i) the collection of the Secured
Obligations, (ii) the enforcement and administration of this Agreement, (iii)
the custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Pledged Collateral, (iv) the exercise or
enforcement of any of the rights of Collateral Agent or any Secured Party
hereunder or (v) the failure by the Pledgor to perform or observe any of the
provisions hereof.  All amounts payable by the Pledgor under this Section 12
shall be due upon demand and shall be part of the Secured Obligations.  The
Pledgor's  obligations under this Section 12 shall survive the termination of
this Agreement and the discharge of such Pledgor's other obligations hereunder.

          No Waiver; Cumulative Remedies.

          No failure on the part of Collateral Agent to exercise, no course of
dealing with respect to, and no delay on the part of Collateral Agent 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 hereunder preclude any other or further exercise thereof or the exercise
of any other right, power or remedy.  The remedies herein provided are
cumulative and are not exclusive of any remedies provided by law.

          In the event Collateral Agent shall have instituted any proceeding to
enforce any right, power or remedy under this instrument by foreclosure, sale,
entry or otherwise, and
<PAGE>   212
such proceeding shall have been discontinued or abandoned for any reason or
shall have been determined adversely to Collateral Agent, then and in every
such case, each Pledgor, Collateral Agent and each holder of any of the Secured
Obligations shall be restored to their respective former positions and rights
hereunder with respect to the Pledged Collateral, and all rights, remedies and
powers of Collateral Agent and the Secured Parties shall continue as if no such
proceeding had been instituted.

          Collateral Agent.  Collateral Agent has been appointed as collateral
agent pursuant to the Credit Agreement.  The actions of Collateral Agent
hereunder are subject to the provisions of the Credit Agreement.  Collateral
Agent shall have the right hereunder to make demands, to give notices, to
exercise or refrain from exercising any rights, and to take or refrain from
taking action (including, without limitation, the release or substitution of
Pledged Collateral), in accordance with this Agreement and the Credit
Agreement.  Collateral Agent may resign and a successor Collateral Agent may be
appointed in the manner provided in the Credit Agreement; provided, however,
that at the time of appointment of a successor Collateral Agent, if Collateral
Agent, through its possession, control, or ownership of Pledged Collateral or
otherwise, holds, owns, or controls any Governmental License issued by the FCC
such that the FCC must consent to the appointment of a successor Collateral
Agent, until the FCC has consented to the appointment of a successor Collateral
Agent the Collateral  Agent shall retain control over such Pledged Collateral
or Government Licenses.  Upon the acceptance of any appointment as Collateral
Agent by a successor Collateral Agent, that successor Collateral Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Collateral Agent under this Agreement, and the
retiring Collateral Agent shall thereupon be discharged from its duties and
obligations under this Agreement.  After any retiring Collateral Agent's
resignation, the provisions of this Agreement shall inure to its benefit as to
any actions taken or omitted to be taken by it under this Agreement while it
was Collateral Agent.

          Collateral Agent May Perform; Collateral Agent Appointed
Attorney-in-Fact.  If the Pledgor shall fail to do any act or thing that it has
covenanted to do hereunder or any warranty on the part of such Pledgor
contained herein shall be breached, Collateral Agent or any Secured Party may
(but shall not be obligated to), subject to the provisions of Section 29 of
this Agreement, do the same or cause it to be done or remedy any such breach,
and may expend funds for such purpose.  Any and all amounts so expended by
Collateral Agent
<PAGE>   213
or such Secured Party shall be paid by such Pledgor promptly upon demand
therefor, with interest at the highest rate then in effect under the Credit
Agreement during the period from and including the date on which such funds
were so expended to the date of repayment.  The Pledgor's obligations under
this Section 15 shall survive the termination of this Agreement and the
discharge of such Pledgor's other obligations under this Agreement, the Credit
Agreement and any other Credit Document.  The Pledgor hereby appoints
Collateral Agent its attorney-in-fact with an interest, with full authority in
the place and stead of such Pledgor and in the name of such Pledgor, or
otherwise, from time to time in Collateral Agent's discretion to take any
action and to execute any instrument consistent with the terms of this
Agreement and the other Credit Documents which the Collateral Agent may deem
necessary or advisable to accomplish the purposes of this Agreement except that
with respect to any FCC applications or filings or other action subject to FCC
rules, regulations and policies, Collateral Agent shall serve as
attorney-in-fact only to the extent permitted under the Communications Act and
FCC rules, regulations and policies.  The foregoing grant of authority is a
power of attorney coupled with an interest and such appointment shall be
irrevocable for the term of this Agreement.  The Pledgor hereby ratifies all
that such attorney shall lawfully do or cause to be done by virtue hereof.

          Indemnity.

          Indemnity.  The Pledgor agrees to indemnify, pay and hold harmless
Collateral Agent and each of the Secured Parties and the officers, directors,
employees, agents and affiliates of Collateral Agent and each of the Secured
Parties (collectively called the "Indemnitees") from and against any and all
other liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, claims, costs (including, without limitation, settlement costs),
expenses or disbursements of any kind or nature whatsoever (including, without
limitation, the reasonable fees and disbursements of counsel for such
Indemnitees in connection with any investigative, administrative or judicial
proceeding commenced or threatened, whether or not such Indemnitee shall be
designated a party thereto), which may be imposed on, incurred by, or asserted
against that Indemnitee, in any manner relating to or arising out of this
Agreement or any other Credit Document (including, without limitation, any
misrepresentation by the Pledgor in this Agreement or any other Credit
Document) (the "indemnified liabilities"); provided that the Pledgors shall not
have any obligation to an Indemnitee hereunder with respect to indemnified
liabilities if it has been determined by a final decision (after all appeals
and the expiration of time to appeal) by a
<PAGE>   214
court of competent jurisdiction that such indemnified liability arose from the
gross negligence or willful misconduct of that Indemnitee.  To the extent that
the undertaking to indemnify, pay and hold harmless set forth in the preceding
sentence may be unenforceable because it is violative of any law or public
policy, each Pledgor shall contribute the maximum portion which it is permitted
to pay and satisfy under applicable law, to the payment and satisfaction of all
indemnified liabilities incurred by the Indemnitees or any of them.

          Survival.  The obligations of each Pledgor contained in this Section
16 shall survive the termination of this Agreement and the discharge of each
Pledgor's other obligations under this Agreement and under the other Credit
Documents.

          Reimbursement.  Any amounts paid by any Indemnitee as to which such
Indemnitee has the right to reimbursement shall constitute Secured Obligations
secured by the Pledged Collateral.

          Modification in Writing.  No amendment, modification, supplement,
termination or waiver of or to any provision of this Agreement, nor consent to
any departure by the Pledgor therefrom, shall be effective unless the same
shall be done in accordance with the terms of the Credit Agreement and unless
in writing and signed by Collateral Agent and Pledgor.  Any amendment,
modification or supplement of or to any provision of this Agreement, any waiver
of any provision of this Agreement, and any consent to any departure by the
Pledgor from the terms of any provision of this Agreement, shall be effective
only in the specific instance and for the specific purpose for which made or
given.  Except where notice is specifically required by this Agreement or any
other Credit Document, no notice to or demand on the Pledgor in any case shall
entitle any such Pledgor to any other or further notice or demand in similar or
other circumstances.

          Termination; Release.  When all the Secured Obligations have been
indefeasibly paid in full and the Commitments of the Banks to make any Loan
under the Credit Agreement shall have expired, this Agreement shall terminate.
Upon termination of this Agreement or any release of Pledged Collateral in
accordance with the provisions of the Credit Agreement, Collateral Agent shall,
upon the request and at the sole cost and expense of the applicable Pledgor,
forthwith assign, transfer and deliver to such Pledgor, against receipt and
without recourse to or warranty by
<PAGE>   215
Collateral Agent, such of the Pledged Collateral to be released (in the case of
a release) as may be in the possession of Collateral Agent and as shall not
have been sold or otherwise applied pursuant to the terms hereof, on the order
of and at the sole cost and expense of such Pledgor, and proper instruments
(including UCC termination statements on Form UCC-3) acknowledging the
termination of this Agreement or the release of such Pledged Collateral, as the
case may be.

          Notices.  Unless otherwise provided herein or in the Credit
Agreement, any notice or other communication herein required or permitted to be
given shall be given in the manner set forth in the Credit Agreement; provided
that notices to Collateral Agent shall not be effective until received by
Collateral Agent.

          Continuing Security Interest; Assignment.  This Agreement shall
create a continuing security interest in the Pledged Collateral and shall (i)
be binding upon each Pledgor, its respective successors and assigns, and  (ii)
inure, together with the rights and remedies of Collateral Agent hereunder, to
the benefit of Collateral Agent and the other Secured Parties and each of their
respective successors, transferees and assigns; no other Persons (including,
without limitation, any other creditor of the Pledgor) shall have any interest
herein or any right or benefit with respect hereto.  Without that limiting the
generality of the foregoing clause (ii), any Bank may assign or otherwise
transfer any indebtedness held by it secured by this Agreement to any other
Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to such Bank, herein or otherwise, subject
however, to the provisions of the Credit Agreement.

          GOVERNING LAW; TERMS.  THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL
BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS, EXCEPT TO THE EXTENT
THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST HEREUNDER, OR REMEDIES
HEREUNDER, IN RESPECT OF ANY PLEDGED COLLATERAL ARE GOVERNED BY THE LAWS OF A
JURISDICTION OTHER THAN THE STATE OF NEW YORK.

          CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  ALL JUDICIAL
PROCEEDINGS BROUGHT AGAINST THE PLEDGOR WITH RESPECT TO THIS AGREEMENT MAY BE
BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE OF
NEW YORK AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT THE PLEDGOR ACCEPTS
FOR ITSELF AND IN CONNECTION WITH ITS
<PAGE>   216
PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE
AFORESAID COURTS, AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED
THEREBY IN CONNECTION WITH THIS AGREEMENT.  THE PLEDGOR DESIGNATES AND APPOINTS
CT CORPORATION SYSTEM, WITH AN ADDRESS AT 1633 BROADWAY, NEW YORK, NEW YORK
10019, AND SUCH OTHER PERSONS AS MAY HEREAFTER BE SELECTED BY THE PLEDGOR
IRREVOCABLY AGREEING IN WRITING TO SO SERVE, AS ITS AGENT TO RECEIVE ON ITS
BEHALF, SERVICE OF ALL PROCESS IN ANY SUCH PROCEEDINGS IN ANY SUCH COURT, SUCH
SERVICE BEING HEREBY ACKNOWLEDGED BY THE PLEDGOR TO BE EFFECTIVE AND BINDING
SERVICE IN EVERY RESPECT.  A COPY OF SUCH PROCESS SO SERVED SHALL BE MAILED BY
REGISTERED MAIL TO THE PLEDGOR AT ITS ADDRESS PROVIDED FOR IN SECTION 19 HEREOF
EXCEPT THAT UNLESS OTHERWISE PROVIDED BY APPLICABLE LAW, ANY FAILURE TO MAIL
SUCH COPY SHALL NOT AFFECT THE VALIDITY OF SERVICE OF PROCESS.  IF ANY AGENT
APPOINTED BY THE PLEDGOR REFUSES TO RECEIVE AND FORWARD SUCH SERVICE, THE
PLEDGOR HEREBY AGREES THAT SERVICE UPON IT BY MAIL SHALL CONSTITUTE SUFFICIENT
NOTICE.  NOTHING HEREIN SHALL  AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER
MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF COLLATERAL AGENT TO BRING
PROCEEDINGS AGAINST PLEDGOR IN THE COURTS OF ANY OTHER JURISDICTION.

          Severability of Provisions.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction.

          Execution in Counterparts.  This Agreement and any amendments,
waivers, consents or supplements hereto may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed and delivered shall be deemed to be an original, but all
such counterparts together shall constitute one and the same agreement.

          Headings.  The Section headings used in this Agreement are for
convenience of reference only and shall not affect the construction of this
Agreement.

          Obligations Absolute.  All obligations of the Pledgor hereunder shall
absolute and unconditional irrespective of:
<PAGE>   217
         any bankruptcy, insolvency, reorganization, arrangement, readjustment,
    composition, liquidation or the like of the Pledgor or any other Credit
    Party;

         any lack of validity or enforceability of the Credit Agreement or any
    other Credit Document or any other agreement or instrument relating
    thereto;

         any change in the time, manner or place of payment of, or in any other
    term of, all or any of the Secured Obligations, or any other amendment or
    waiver of or any consent to any departure from the Credit Agreement, any
    other Credit Document or any other agreement or instrument relating
    thereto;

         any exchange, release or non-perfection of any other collateral, or
    any release or amendment or waiver of  or consent to any departure from any
    guarantee, for all or any of the Secured Obligations;

         any exercise or non-exercise, or any waiver of any right, remedy,
    power or privilege under or in respect of this Agreement, or any other
    Credit Document except as specifically set forth in a waiver granted
    pursuant to the provisions of Section 17 hereof; or

         any other circumstances which might otherwise constitute a defense
    available to, or a discharge of, any other Pledgor.

          Collateral Agent's Right to Sever Indebtedness.

          The Pledgor acknowledges that (i) the Pledged Collateral does not
constitute the sole source of security for the payment and performance of the
Secured Obligations and that the Secured Obligations are also secured by other
types of property of such Pledgor and its Affiliates in other jurisdictions
(all such property, collectively, the "Collateral"), (ii) the number of such
jurisdictions and the nature of the transaction of which this instrument is a
part are such that it would have been impracticable for the parties to allocate
to each item of Collateral a specific loan amount and to execute in respect of
such item a separate credit agreement, and (iii) each Pledgor intends that
Collateral Agent have the same rights with respect to the Pledged Collateral,
in any judicial proceeding relating to the exercise of any right or remedy
hereunder or otherwise,
<PAGE>   218
that Collateral Agent would have had if each item of collateral had been
pledged or encumbered pursuant to a separate credit agreement and security
instrument.  In furtherance of such intent, each Pledgor agrees to the greatest
extent permitted by law that Collateral Agent may at any time by notice (an
"Allocation Notice") to the Pledgor allocate a portion of the Secured
Obligations (the "Allocated Indebtedness") to the Pledged Collateral of such
Pledgor and sever from the remaining Secured Obligations the Allocated
Indebtedness.  From and after the giving of an Allocation Notice with respect
to the Pledged Collateral, the Secured Obligations hereunder shall be limited
to the extent set forth in the Allocation Notice and (as so limited) shall, for
all purposes, be construed as a separate credit obligation of each Pledgor
unrelated to the other transactions contemplated by the Credit Agreement or any
other Credit Document or any document related to either thereof.  To the extent
that the proceeds of any  judicial proceeding relating to the exercise of any
right or remedy hereunder of the Pledged Collateral shall exceed the Allocated
Indebtedness, such proceeds shall belong to such Pledgor and shall not be
available hereunder to satisfy any Secured Obligations of such Pledgor other
than the Allocated Indebtedness.  In any action or proceeding to exercise any
right or remedy under this Agreement which is commenced after the giving by
Collateral Agent of an Allocation Notice, the Allocation Notice shall be
conclusive proof of the limits of the Secured Obligations hereby secured, and
the Pledgor may introduce, by way of defense or counterclaim, evidence thereof
in any such action or proceeding.  Notwithstanding any provision of this
Section 27, the proceeds received by Collateral Agent pursuant to this
Agreement shall be applied by Collateral Agent in accordance with the
provisions of Section 11 hereof.

          The Pledgor hereby waives to the greatest extent permitted under law
the right to a discharge of any of the Secured Obligations under any statute or
rule of law now or hereafter in effect which provides that the exercise of any
particular right or remedy as provided for herein (by judicial proceedings or
otherwise) constitutes the exclusive means for satisfaction of the Secured
Obligations or which makes unavailable any further judgment or any other right
or remedy provided for herein because Collateral Agent elected to proceed with
the exercise of such initial right or remedy or because of any failure by
Collateral Agent to comply with laws that prescribe conditions to the
entitlement to such subsequent judgment or the availability of such subsequent
right or remedy.  In the event that, notwithstanding the foregoing waiver, any
court shall for any reason hold that such subsequent judgment or action is not
available to Collateral Agent, no Pledgor shall (i) introduce in any other
jurisdiction any judgment so holding as a defense to enforcement against such
Pledgor of any remedy in the Credit
<PAGE>   219
Agreement or executed in connection with the Credit Agreement or (ii) seek to
have such judgment recognized or entered in any other jurisdiction, and any
such judgment shall in all events be limited in application only to the state
or jurisdiction where rendered and only with respect to the collateral referred
to in such judgment.

          In the event any instrument in addition to the Allocation Notice is
necessary to effectuate the provisions of this Section 27, including, without
limitation, any amendment to this Agreement, any substitute promissory note or
affidavit or certificate of any kind, Collateral Agent may execute and deliver
such instrument as the attorney-in-fact of the Pledgor.

          Notwithstanding anything set forth herein to the contrary, the
provisions of this Section 27 shall be effective only to the maximum extent
permitted by law.

          Future Advances.  This Agreement shall secure the payment of any
amounts advanced from time to time pursuant to the Credit Agreement.

          Facilitating Governmental Approvals; Specific Performance.

          In connection with the exercise by Collateral Agent of its rights
under this Agreement relating to the disposition of the Pledged Collateral as
it may affect the control of any Governmental License issued by the FCC or any
other authorizations, agreements, permits, licenses, and franchises of the
Pledgor, it may be necessary to obtain the prior consent or approval of the FCC
or other Governmental Authority to the exercise of Collateral Agent's rights
with respect to the Pledged Collateral.  To the extent that any such consent or
approval is required for any action that Collateral Agent may take under this
Agreement with respect to the Pledged Collateral, receipt of such FCC or
Governmental Authority approval shall be a condition precedent to Collateral
Agent's exercise of such rights.  In furtherance of the first sentence of this
Section, the Pledgor hereby agrees, at its own cost, to use its best efforts to
take any and all actions which Collateral Agent may request in order to obtain
such consents or approvals or any other governmental authorization as may be
necessary to enable Collateral Agent to exercise and enjoy the full rights and
benefits granted to it under this Agreement, the Credit Agreement, or any other
Credit Document, including, without limitation, the preparation, execution,
delivery or filing on
<PAGE>   220
the Pledgor's behalf and in such Pledgor's name, or in such other name as may
be appropriate or required, or causing to be prepared, executed, delivered or
filed, all applications, certificates, filings, instruments, information,
reports and other documents (including, without limitation, any application for
any assignment or transfer of control or ownership).

         The Pledgor hereby acknowledges that a breach of any of its respective
obligations contained in this Agreement will cause irreparable injury to
Collateral Agent, and that such a breach would not be adequately compensable in
damages, and therefore Pledgors agree that their obligations under this
Agreement shall be specifically enforceable.
<PAGE>   221
         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed and delivered as of the date first above written.

         This SECURITIES PLEDGE AGREEMENT (the "Agreement"), dated as of
February 26, 1997, made by AMERICAN TELECASTING OF GREEN BAY, INC., a Delaware

BRANCH, having an office at 1211 Avenue of the Americas, New York, New York
10036, as pledgee, assignee and secured party, in its capacity as collateral
agent (in such capacities and together with any successors in such capacities,
the "Collateral Agent") for the lending institutions (the "Banks") under the
Credit Agreement (as hereinafter defined).

                               R E C I T A L S :

         A.  Pursuant to a certain credit agreement, dated as of the date
hereof (as amended, amended and restated, supplemented or otherwise modified
from time to time, the "Credit Agreement"; unless otherwise defined herein,
capitalized terms used herein have the meanings assigned to them in the Credit
Agreement), among American Telecasting, Inc. ("ATel"), the Banks and Banque

make to or for the account of ATel certain Loans up to an aggregate principal
amount of $17,000,000.

         B.  The Pledgor is the legal and beneficial owner of the Pledged
Collateral (as hereinafter defined) pledged by it.

         C.  It is a condition precedent to the obligations of the Banks to
make the Loans under the Credit Agreement that the Pledgor execute and deliver
the applicable Credit Documents, including this Agreement.

         D.  The Pledgor has executed and delivered to Collateral Agent a
certain guarantee instrument (the "Guarantee") pursuant to which, among other
things, the Pledgor has guaranteed the obligations of ATel under the

Guarantee be secured hereunder.

         E.  This Agreement is given by the Pledgor in favor of Collateral
Agent for its benefit and the benefit of the Banks and the Agent (collectively,
the "Secured Parties") to secure the payment and performance of all of the

                              A G R E E M E N T :

    Pledged Shares from time to time acquired by the Pledgor in any manner
    (which securities shall be deemed to be part of the Pledged Shares) and the
    certificates representing such additional securities and any interest of
    the Pledgor in the entries on the books of any financial intermediary
    pertaining to such additional securities;

<PAGE>   224

    acquired by Pledgor in any way, and all certificates or instruments
    evidencing such Intercompany Notes and all proceeds thereof, all accessions
    thereto and substitutions therefor;

         (d) all dividends, cash, options, warrants, rights, instruments,

    interests or proceeds from time to time received, receivable or otherwise
    distributed to the Pledgor in respect of or in exchange for any or all of
    the Pledged Shares (collectively, "Distributions"); and

         (e) all Proceeds (as defined under the Uniform Commercial Code as in
    effect in any relevant jurisdiction (the "UCC") or under other relevant
    law) of any of the foregoing, and in any event, including, without
    limitation, any and all (i) proceeds of any insurance (except payments made
    to a Person which is not a party to this Agreement), indemnity, warranty or
    guarantee payable to Collateral Agent or to the Pledgor from time to time
    with respect to any of its respective Pledged Collateral, (ii) payments (in
    any form whatsoever) made or due and payable to the Pledgor from time to

    seizure or forfeiture Collateral of all or any part of its respective
    Pledged Collateral by any Governmental Authority (or any person acting
    under color of a Governmental Authority), (iii) instruments representing
    obligations to pay amounts in respect of Pledged Shares, (iv) products of
    the Pledged Collateral and (v) other amounts from time to time paid or

<PAGE>   225

362(a)) of (i) all Obligations of the Pledgor now existing or hereafter arising

Pledgor's obligations to pay principal, interest and all other charges, fees,
expenses, commissions, reimbursements, premiums, indemnities and other payments
related to or in respect of the obligations contained in the Guarantee), (ii)
all Obligations of the Pledgor now existing or hereafter arising under or in

payments related to or in respect of the Obligations contained in the Credit
Agreement), and (iii) without duplication of the amounts described in clauses

under or in respect of this Agreement or any other Security Document,
including, without limitation, with respect to all reasonable charges, fees,
expenses, commissions,  reimbursements, premiums, indemnities and other
payments related to or in respect of the obligations contained in this
Agreement (the obligations described in clauses (i), (ii) and (iii),
collectively, the "Secured Obligations").

         Section 3.  No Release.  Subject to Section 18 of this Agreement,
nothing set forth in this Agreement shall relieve the Pledgor from the
performance of any term, covenant, condition on the Pledgor's part to be
performed or observed under or in respect of any of the Pledged Collateral or
from any liability to the Person under or in respect of any of the Pledged
Collateral or shall impose any obligation on Collateral Agent or any Secured
Party to perform or observe any such term, covenant, condition or agreement on
the Pledgor's part to be so performed or observed or shall impose any liability
on Collateral Agent or any Secured Party for any act or omission on the part of
the Pledgor relating thereto or for any breach of any representation or
warranty on the part of the Pledgor contained in this Agreement, or any other
Credit Document or under or in respect of the Pledged Collateral or made in
connection herewith or therewith.  Subject to Section 18 of this Agreement, the
obligations of the Pledgor contained in this Section 3 shall survive the

obligations under this Agreement and the other Credit Documents.

<PAGE>   226

         Section 4.  Delivery of Pledged Collateral.

         (a) All certificates, agreements or instruments representing or
evidencing the Pledged Collateral, to the extent not previously delivered to
Collateral Agent, shall immediately upon receipt thereof by the Pledgor be
delivered to and held by or on behalf of Collateral Agent pursuant hereto.  All
Pledged Collateral shall be in suitable form for transfer by delivery or shall
be accompanied by duly executed instruments of transfer or assignment in blank
(with signatures appropriately guaranteed), all in form and substance
satisfactory to Collateral Agent.  Subject to the provisions of Section 29 of
this Agreement, Collateral Agent shall have the right, at any time upon the
occurrence and during the continuance of an Event of Default, to endorse,
assign or otherwise transfer to or to register in the name of Collateral Agent
or any of its nominees any or all of the Pledged Collateral.  Collateral Agent
shall provide the Pledgor with notice of any endorsement, assignment or other
transfer made pursuant to the preceding sentence.  In addition, upon the
occurrence and during the continuance of an Event of Default, Collateral Agent
shall have the right at any  time to exchange certificates representing or
evidencing Pledged Collateral for certificates of smaller or larger
denominations.

         (b) If an issuer of Pledged Shares is incorporated in a jurisdiction
which does not permit the use of certificates to evidence equity ownership,
then the Pledgor shall, to the extent permitted by applicable law, record such
pledge on the stock register of such issuer, execute any customary stock pledge
forms or other documents necessary or appropriate to complete the pledge and
give Collateral Agent the right to transfer the Pledged Shares under the terms
hereof and provide to Collateral Agent an opinion of counsel, in form and
substance satisfactory to Collateral Agent, confirming such pledge.

         (c) Notwithstanding any provision of this Section 4 to the contrary,
if the exercise of any rights provided in this Section 4 or Section 10 relates
to the ownership or control of any radio, television or other license, permit,
certificate or approval granted or issued by the FCC or any other Governmental
Authority (including, without limitation, any multichannel or single channel
multipoint distribution

<PAGE>   227

service, local multipoint distribution service, operational-fixed microwave
service, cable television relay service station, business radio, instructional
television fixed service, earth station or experimental licenses or permits
issued by the FCC) (each, a "Governmental License") held by the Pledgor or a
subsidiary of the Pledgor and it may be necessary to obtain the consent or
approval of the FCC prior to the exercise of such rights, the provisions of
Section 29 of this Agreement shall apply.

         Section 5.  Supplements, Further Assurances.

         (a) The Pledgor agrees that at any time and from time to time, at the
sole cost and expense of such Pledgor, the Pledgor shall promptly execute and
deliver all further instruments and documents, including, without limitation,
supplemental or additional UCC-1 financing statements, and take all further
action that may be necessary or that Collateral Agent may reasonably request,
in order to perfect and protect the pledge, security interest and Lien granted
or purported to be granted hereby or to enable Collateral Agent to exercise and
enforce its rights and remedies hereunder with respect to any Pledged
Collateral.

         (b) The Pledgor shall, upon obtaining any Pledged Shares of any Person
promptly (and in any event within three Business Days) deliver to Collateral
Agent a pledge amendment, duly executed by the Pledgor, in substantially the
form of Exhibit 1 hereto (the "Pledge Amendment"), in respect of the additional
Pledged Shares which are to be pledged pursuant to this Agreement, and
confirming the attachment of the Lien hereby created on and in respect of such
Pledged Collateral.  The Pledgor hereby authorizes Collateral Agent to attach
each Pledge Amendment to this Agreement and agrees that all Pledged Shares
listed on any Pledge Amendment delivered to Collateral Agent shall for all
purposes hereunder be considered Pledged Collateral.

         Section 6.  Representations, Warranties and Covenants.  The Pledgor
represents, warrants and covenants as follows (as to itself only):

<PAGE>   228

         (a) No Liens.  The Pledgor is, and at the time of any delivery of any
    Pledged Collateral to Collateral Agent pursuant to Section 4 of this
    Agreement will be, the sole legal and beneficial owner of the Pledged
    Collateral pledged by it pursuant to this Agreement.  All Pledged
    Collateral is on the date, and will be, so owned by the Pledgor, as
    applicable, free and clear of any Lien except for the Lien created by this
    Agreement.

         (b) Authorization, Enforceability.  The Pledgor has the requisite
    corporate power, authority and legal right to pledge and grant a security
    interest in all of the Pledged Collateral pledged by it pursuant to this
    Agreement, and this Agreement constitutes the legal, valid and binding
    obligation of the Pledgor, enforceable against the Pledgor in accordance
    with its terms.

         (c) No Consents, etc.  No consent of any party (including, without
    limitation, any stockholders or creditors of the Pledgor) and no consent,
    authorization, approval, or other action by, and no notice to or filing
    with, any Governmental Authority or regulatory body or other Person is
    required either (x) for the pledge by the Pledgor of the Pledged Collateral
    pledged by it pursuant to this Agreement or for the execution, delivery or
    performance of this Agreement by the Pledgor, or (y) for the exercise by
    Collateral Agent of the voting or other rights provided for in this
    Agreement, or (z) for the exercise by Collateral Agent of the remedies in
    respect of the Pledged Collateral pursuant to this Agreement; provided,
    however, that under the Communications Act and the rules and regulations of
    the FCC, FCC consent may be required prior to the transfer of control or
    assignment of any Governmental License issued by the FCC, or the exercise
    of any voting rights or management over the Pledgor or an issuer of Pledged
    Shares to the extent it holds, owns or controls any Governmental License
    issued by the FCC.

         (d) Due Authorization and Issuance.  All of the Pledged Shares have
    been, and to the extent hereafter issued will be upon such issuance, duly
    authorized and validly issued and fully paid and nonassessable.

<PAGE>   229

         (e) Chief Executive Office.  The Pledgor's chief executive office is
    located at 5575 Tech Center Drive, Suite 300, Colorado Springs, Colorado
    80919.  Pledgor shall not move its chief executive office except to such
    new location as Pledgor may establish in accordance with the last sentence
    of this Section 6(e).  Pledgor shall not establish a new location for its
    chief executive office nor shall it change its name until (i) it shall have
    given Collateral Agent not less than 45 days' prior written notice of its
    intention so to do, clearly describing such new location or name and
    providing such other information in connection therewith as Collateral
    Agent or any Secured Party may request, and (ii) with respect to such new
    location or name, Pledgor shall have taken all action satisfactory to
    Collateral Agent and the Secured Parties to maintain the perfection and
    priority of the security interest of Collateral Agent for the benefit of
    the Secured Parties in the Pledged Collateral intended to be granted
    hereby.

         (f) Delivery of Pledged Collateral; Filings.  The Pledgor has
    delivered to Collateral Agent all certificates representing the Pledged
    Shares and Intercompany Notes and has caused to be filed with the Secretary
    of State of the State of New York, the State of incorporation of the
    Pledgor and the State of Colorado, which is the State of the chief
    executive office of the Pledgor, UCC-1 financing statements evidencing the
    Lien created by this Agreement, and such delivery, filing and pledge of the
    Pledged Collateral pursuant to this Agreement creates a valid and perfected
    first priority security interest in the Pledged Collateral securing the
    payment of the Secured Obligations pursuant to the UCC, including, without
    limitation, the  UCC as in effect in the States of New York, the State of
    incorporation of the Pledgor and the State of Colorado, which is the State
    of the chief executive office of the Pledgor.

         (g) Pledged Collateral.  All information set forth herein, including
    the Schedules annexed hereto, and all information contained in any
    documents, schedules and lists heretofore delivered to any Secured Party in
    connection with this Agreement, in each case, relating to the Pledged
    Collateral is accurate and complete in all respects.

<PAGE>   230

         (h) No Violations, etc.  The pledge of the Pledged Collateral pursuant
    to this Agreement does not violate Regulation G, T, U or X of the Federal
    Reserve Board.

         (i) Ownership of Pledged Collateral.  Except as otherwise permitted by
    the Credit Agreement, the Pledgor at all times will be the sole beneficial
    owner of the Pledged Collateral pledged by it pursuant to this Agreement.

         (j) No Options, Warrants, etc.  Except as disclosed in the Credit
    Agreement, there are no options, warrants, calls, rights, commitments or
    agreements of any character to which the Pledgor is a party or by which it
    is bound obligating the Pledgor to issue, deliver or sell or cause to be
    issued, delivered or sold, additional securities of any issuer of the
    Pledged Shares or obligating any issuer of the Pledged Shares to grant,
    extend or enter into any such option, warrant, call, right, commitment or
    agreement.  There are no voting trusts or other agreements or
    understandings to which the Pledgor or any issuer of the Pledged Shares is
    a party with respect to the voting of the securities of any issuer of the
    Pledged Shares.

         (k) Endorsement, Assignment or Pledge of Instruments.  None of the
    Pledged Collateral is, as of the date of this Agreement, and as to Pledged
    Collateral which arises from time to time after such date will be,
    evidenced by any instrument, note or chattel paper, except such as have
    been or will be endorsed, assigned or pledged and delivered to Collateral
    Agent by Pledgors simultaneously with the creation thereof.

         (l) Systems.  The Pledged Shares include the Pledgor's interest in
    each Credit Party operating Systems or holding System Agreements.

         Section 7.  Voting Rights; Distributions; etc.

         (a) So long as no Event of Default shall have occurred and be
continuing:

<PAGE>   231

         (i) The Pledgor shall be entitled to exercise any and all voting and
    other consensual rights pertaining to the Pledged Shares pledged by it
    pursuant to this Agreement or any part thereof for any purpose not
    inconsistent with the terms or purpose of this Agreement or any of the
    other Credit Documents and each Pledgor shall not in any event exercise
    such rights in any manner which may have an adverse effect on the value of
    its respective Pledged Collateral or the security intended to be provided
    by this Agreement.

         (ii)    Subject to the terms of the Credit Agreement, each Pledgor
    shall be entitled to receive and retain, and to utilize free and clear of
    the Lien of this Agreement, any and all Distributions, but only if and to
    the extent made in accordance with the provisions of the Credit Agreement;
    provided, however, that any and all such Distributions consisting of rights
    or interests in the form of securities shall be, and shall be forthwith
    delivered to Collateral Agent to hold as Pledged Collateral and shall, if
    received by the Pledgor, be received in trust for the benefit of Collateral
    Agent, be segregated from the other property or funds of such Pledgor, and
    be forthwith delivered to Collateral Agent as Pledged Collateral in the
    same form as so received (with any necessary endorsement).

         (iii)   Collateral Agent shall be deemed without further action or
    formality to have granted to each Pledgor all necessary consents relating
    to voting rights and shall, if necessary, upon written request of the
    Pledgor and at such Pledgor's sole cost and expense, from time to time
    execute and deliver (or cause to be executed and delivered) to such Pledgor
    all such instruments as such Pledgor may reasonably request in order to
    permit such Pledgor to exercise the voting and other rights which it is
    entitled to exercise pursuant to Section 7(a)(i) hereof and to receive the
    Distributions which it is authorized to receive and retain pursuant to
    Section 7(a)(ii) hereof.

         (b) Upon the occurrence and during the continuance of an Event of
Default:

<PAGE>   232

         (i) All rights of the Pledgor to exercise the voting and other
    consensual rights it would otherwise be entitled to exercise pursuant to
    Section 7(a)(i) hereof without any action or the giving of any notice shall
    cease, and all such rights shall thereupon become vested in Collateral
    Agent, which shall thereupon have the sole right to exercise such voting
    and other consensual rights; provided, however, to the extent the Pledgor
    or an issuer of Pledged Shares hold, own or control any Governmental
    License issued by the FCC, if and to the extent required under the
    Communications Act or the FCC's rules, until the FCC has consented to a
    transfer of control or assignment of Pledgor, an issuer of Pledged Shares,
    or such Governmental License issued by the FCC, Pledgor shall continue to
    exercise the voting and other consensual rights.

         (ii)    All rights of the Pledgor to receive Distributions which it
    would otherwise be authorized to receive and retain pursuant to Section
    7(a)(ii) hereof shall cease and all such rights shall thereupon become
    vested in Collateral Agent, which shall thereupon have the sole right to
    receive and hold as Pledged Collateral such Distributions.

         (iii)   Subject to any necessary prior or subsequent FCC approval,
    Collateral Agent shall be entitled to the appointment, as a matter of right
    and without giving notice to the Pledgor, of a receiver with respect to the
    Pledged Collateral, without regard to the adequacy or inadequacy of any
    Pledged Collateral for the Secured Obligations or the solvency or
    insolvency of any person or entity then legally or equitably liable for the
    Secured Obligations or any portion thereof, and each Pledgor does hereby
    irrevocably consent to such appointment.  Any such receiver shall have all
    the usual qualifications, powers and duties of receivers in similar cases,
    including the full power to conduct the business of the Pledgors.

         (c) The Pledgor shall, at such Pledgor's sole cost and expense, from
time to time execute and deliver to Collateral Agent and any other Person
directed by Collateral Agent,  appropriate instruments as Collateral Agent may
request in order to permit Collateral Agent to exercise the

<PAGE>   233

voting and other rights which it may be entitled to exercise pursuant to
Section 7(b)(i) hereof and to receive all Distributions which it may be
entitled to receive under Section 7(b)(ii) hereof.

         (d) All Distributions which are received by the Pledgor contrary to
the provisions of Section 7(b)(ii) hereof shall be received in trust for the
benefit of Collateral Agent, shall be segregated from other funds of such
Pledgor and shall immediately be paid over to Collateral Agent as Pledged
Collateral in the same form as so received (with any necessary endorsement).

         Section 8.  Transfers and Other Liens; Additional Shares; Principal
Office.

         (a) The Pledgor shall not (i) sell, convey, assign or otherwise
dispose of, or grant any option, right or warrant with respect to, any of the
Pledged Collateral pledged by it pursuant to this Agreement, (ii) create or
permit to exist any Lien upon or with respect to any Pledged Collateral pledged
by it pursuant to this Agreement other than the Lien granted to Collateral
Agent under this Agreement, or (iii) permit any issuer of the Pledged Shares to
merge, consolidate or change its legal form unless a majority of the
outstanding capital stock of the surviving or resulting corporation is, upon
such merger or consolidation, pledged to Collateral Agent pursuant to a pledge
agreement in form and substance, satisfactory to Collateral Agent, and no cash,
securities or other property is distributed in respect of the outstanding
shares of any other constituent corporation.

         (b) The Pledgor shall (i) cause each issuer of the Pledged Shares not
to issue any stock or other securities in addition to or in substitution for
the Pledged Shares issued by such issuer, except to such Pledgor and (ii)
pledge hereunder, immediately upon its acquisition (directly or indirectly)
thereof, any and all additional shares of capital stock or other equity
securities of any issuer of the Pledged Shares which are required to be pledged
hereunder.

<PAGE>   234

         Section 9.  Reasonable Care.  Collateral Agent shall be deemed to have
exercised reasonable care in the custody and preservation of the Pledged
Collateral in its possession if such Pledged Collateral is accorded treatment
substantially equivalent to that which Collateral Agent, in its individual
capacity, accords its own property consisting of similar instruments or
interests, it being understood that neither the Collateral Agent nor any of the
Secured Parties shall have responsibility for (i) ascertaining or taking action
with respect to calls, conversions, exchanges, maturities, tenders or other
matters relating to any Pledged Collateral, whether or not Collateral Agent or
any other Secured Party has or is deemed to have knowledge of such matters, or
(ii) taking any necessary steps to preserve rights against any Person with
respect to any Pledged Collateral.

         Section 10. Remedies Upon Default; Decisions Relating to Exercise of
Remedies.

         (a)If any Event of Default shall have occurred and be continuing,
subject to the provisions of Section 29 of this Agreement, Collateral Agent
shall have the right, in addition to other rights and remedies provided for
herein or otherwise available to it to be exercised from time to time, (i) to
retain and apply the Distributions to the Secured Obligations as provided in
Section 11 hereof, and (ii) to exercise all the rights and remedies of a
secured party on default under the UCC, and Collateral Agent may also in its
sole discretion, without notice except as specified below, sell the Pledged
Collateral or any part thereof (including, without limitation, any partial
interest in the Pledged Shares) in one or more parcels at public or private
sale, at any exchange, broker's board or at any of Collateral Agent's offices
or elsewhere, for cash, on credit or for future delivery, and at such price or
prices and upon such other terms as Collateral Agent may deem commercially
reasonable, irrespective of the impact of any such sales on the market price of
the Pledged Collateral.  Collateral Agent or any other Secured Party or any of
their respective Affiliates may be the purchaser of any or all of the Pledged
Collateral at any such sale and shall be entitled, for the purpose of bidding
and making settlement or payment of the purchase price for all or any portion
of the Pledged Collateral sold at such sale, to use and apply any of the
Secured Obligations owed to such Person as a credit on account of the purchase

<PAGE>   235

price of any Pledged Collateral payable by such Person at such sale.  Each
purchaser at any such sale shall acquire the property sold absolutely free from
any claim or right on the part of the Pledgor, and Pledgor hereby waives (to
the fullest extent permitted by law) all rights of redemption, stay and/or
appraisal which it now has or may at any time in the future have under any rule
of law or statute now existing or hereafter enacted.  The Pledgor acknowledges
and agrees that, to the extent notice of sale  shall be required by law, five
(5) days' notice to such Pledgor of the time and place of any public sale or
the time after which any private sale is to be made shall constitute reasonable
notification.  No notification need be given to the Pledgor if it has signed,
after the occurrence of an Event of Default, a statement renouncing or
modifying any right to notification of sale or other intended disposition.
Collateral Agent shall not be obligated to make any sale of Pledged Collateral
regardless of notice of sale having been given.  Collateral Agent may adjourn
any public or private sale from time to time by announcement at the time and
place fixed therefor, and such sale may, without further notice, be made at the
time and place to which it was so adjourned.  The Pledgor hereby waives any
claims against Collateral Agent arising by reason of the fact that the price at
which any Pledged Collateral may have been sold at such a private sale was less
than the price which might have been obtained at a public sale, even if
Collateral Agent accepts the first offer received and does not offer such
Pledged Collateral to more than one offeree.  Notwithstanding any provision of
this subsection 10(a) to the contrary, in the event of a private or public sale
of the Pledged Collateral, prior to the consummation of the sale, to the extent
required under the Communications Act of 1934, as amended, or any successor
statute or law (the "Communications Act"), the prior consent of the FCC
pursuant to the Communications Act and the rules and regulations of the FCC
will be obtained.

         (b) The Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended (the "Securities Act"), and
applicable state securities laws, Collateral Agent may be compelled, with
respect to any sale of all or any part of the Pledged Collateral, to limit
purchasers to Persons who will agree, among other things, to acquire the
Pledged Collateral for their own account, for investment and not with a view to
the distribution or resale thereof.  The Pledgor acknowledges that any such
private sales may be at prices and on terms

<PAGE>   236

less favorable to Collateral Agent than those obtainable through a public sale
without such restrictions (including, without limitation, a public offering
made pursuant to a registration statement under the Securities Act), and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner and that
Collateral Agent shall have no obligation to engage in public sales and no
obligation to delay the sale of any Pledged Collateral for the period of time
necessary to permit the issuer thereof to register it for a form of public sale
requiring registration under the Securities Act or under applicable state
securities laws, even if such issuer would agree to do so.

         (c) Notwithstanding the foregoing and to the extent commercially
reasonable, each Pledgor shall, upon the occurrence and during the continuance
of an Event of Default, at the request of Collateral Agent, for the benefit of
Collateral Agent, cause any registration, qualification under or compliance
with any federal or state securities law or laws to be effected with respect to
all or any part of the Pledged Collateral as soon as practicable and at such
Pledgor's sole cost and expense.  The Pledgor will use its best efforts to
cause such registration to be effected (and be kept effective) and will use its
best efforts to cause such qualification and compliance to be effected (and be
kept effective) as may be so requested and as would permit or facilitate the
sale and distribution of such Pledged Collateral, including, without
limitation, registration under the Securities Act (or any similar statute then
in effect), appropriate qualifications under applicable blue sky or other state
securities laws and appropriate compliance with any other government
requirements.  The Pledgor will cause Collateral Agent to be kept advised in
writing as to the progress of each such registration, qualification or
compliance and as to the completion thereof, will furnish to Collateral Agent
such number of prospectuses, offering circulars or other documents incident
thereto as Collateral Agent from time to time may request, and will indemnify
and will cause the issuer of the Pledged Collateral to indemnify Collateral
Agent and all others participating in the distribution of such Pledged
Collateral against all claims, losses, damages and liabilities caused by any
untrue statement (or alleged untrue statement) of a material fact contained
therein (or in any related registration

<PAGE>   237

statement, notification or the like) or by any omission (or alleged omission)
to state therein (or in any related registration statement, notification or the
like) a material fact required to be stated therein or necessary to make the
statements therein not misleading.

         (d) If Collateral Agent determines to exercise its right to sell any
or all of the Pledged Collateral, upon written request, each Pledgor shall from
time to time furnish to Collateral Agent all such information as Collateral
Agent may request in order to determine the number of securities included in
the Pledged Collateral which may be sold by Collateral Agent as exempt
transactions under the Securities Act and the rules  of the Securities and
Exchange Commission thereunder, as the same are from time to time in effect.

         (e) The Pledgor recognizes that, by reason of certain prohibitions
contained in laws, rules, regulations or orders of any foreign Governmental
Authority, Collateral Agent may be compelled, with respect to any sale of all
or any part of the Pledged Collateral, to limit purchasers to those who meet
the requirements of such foreign Governmental Authority.  The Pledgor
acknowledges that any such sales may be at prices and on terms less favorable
to Collateral Agent than those obtainable through a public sale without such
restrictions, and, notwithstanding such circumstances, agrees that any such
restricted sale shall be deemed to have been made in a commercially reasonable
manner and that Collateral Agent shall have no obligation to engage in public
sales.

         (f) In addition to any of the other rights and remedies hereunder,
Collateral Agent shall have the right to institute a proceeding seeking
specific performance in connection with any of the agreements or obligations
hereunder.

         (g) Without limiting the generality of the provisions in Section 15
hereof, Pledgor hereby constitutes and appoints Collateral Agent, with full
power of substitution, its true and lawful attorney-in-fact, in its name, place
and stead to take any action upon the occurrence and during the continuance of
an Event of Default required to reflect the foreclosure sale of the Pledged
Collateral or the exercise of any remedy hereunder.  The foregoing grant of
authority is a power of attorney coupled with an interest and

<PAGE>   238

such appointment shall be irrevocable for the term of this Agreement.

         Section 11. Application of Proceeds.  All Distributions held from time
to time by Collateral Agent and all cash proceeds received by Collateral Agent
in respect of any sale of, collection from, or other realization upon all or
any part of the Pledged Collateral pursuant to the exercise by Collateral Agent
of its remedies as a secured creditor as provided in Section 10 hereof shall be
applied, together with any other sums then held by Collateral Agent pursuant to
this Agreement, promptly by Collateral Agent as follows:

         First, to the payment of all reasonable costs and expenses, fees,
    commissions and taxes of such sale, collection or other realization,
    including, without limitation, reasonable compensation to Collateral Agent
    and its agents and counsel, and all reasonable expenses, liabilities and
    advances made or incurred by Collateral Agent in connection therewith,
    together with interest on each such amount at the highest rate then in
    effect under the Credit Agreement from and after the date such amount is
    due, owing or unpaid until paid in full;

         Second, to the payment of all other reasonable costs and expenses of
    such sale, collection or other realization, including, without limitation,
    reasonable compensation to the Banks and their agents and counsel and all
    reasonable expenses, liabilities and advances made or incurred by the Banks
    in connection therewith, together with interest on each such amount at the
    highest rate then in effect under the Credit Agreement from and after the
    date such amount is due, owing or unpaid until paid in full;

         Third, to the indefeasible payment in full in cash of interest and all
    amounts other than principal under the Credit Agreement at any time and
    from time to time owing by the Pledgor under or in connection with the
    Credit Agreement, ratably according to the unpaid amounts thereof, without
    preference or priority of any kind among amounts so due and payable,
    together with

<PAGE>   239

    interest on each such amount at the highest rate then in effect under the
    Credit Agreement from and after the date such amount is due, owing or
    unpaid until paid in full;

         Fourth, to the indefeasible payment in full in cash of principal at
    any time and from time to time owing by the Pledgor under or in connection
    with the Credit Agreement, ratably according to the unpaid amounts thereof,
    without preference or priority of any kind, among amounts of principal so
    due and payable, together with interest on each such amount at the highest
    rate then in effect under the Credit Agreement from and after the date such
    amount is due, owing or unpaid until paid in full; and

         Fifth, to the applicable Pledgor, or its successors or assigns or to
    whomsoever may be lawfully entitled to receive the same or as a court of
    competent jurisdiction may direct, of any surplus then remaining from such
    proceeds.

         Section 12. Expenses.  The Pledgor will upon demand pay to Collateral
Agent the amount of any and all expenses, including the reasonable fees and
expenses of its counsel and the fees and expenses of any experts and agents,
which Collateral Agent may incur in connection with (i) the collection of the
Secured Obligations, (ii) the enforcement and administration of this Agreement,
(iii) the custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Pledged Collateral, (iv) the exercise or
enforcement of any of the rights of Collateral Agent or any Secured Party
hereunder or (v) the failure by the Pledgor to perform or observe any of the
provisions hereof.  All amounts payable by the Pledgor under this Section 12
shall be due upon demand and shall be part of the Secured Obligations.  The
Pledgor's obligations under this Section 12 shall survive the termination of
this Agreement and the discharge of such Pledgor's other obligations hereunder.

         Section 13. No Waiver; Cumulative Remedies.

<PAGE>   240

         (a) No failure on the part of Collateral Agent to exercise, no course
of dealing with respect to, and no delay on the part of Collateral Agent 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 hereunder preclude any other or further exercise thereof or the exercise
of any other right, power or remedy.  The remedies herein provided are
cumulative and are not exclusive of any remedies provided by law.

         (b) In the event Collateral Agent shall have instituted any proceeding
to enforce any right, power or remedy under this instrument by foreclosure,
sale, entry or otherwise, and such proceeding shall have been discontinued or
abandoned for any reason or shall have been determined adversely to Collateral
Agent, then and in every such case, each Pledgor, Collateral Agent and each
holder of any of the Secured Obligations shall be restored to their respective
former positions and rights hereunder with respect to the Pledged Collateral,
and all rights, remedies and powers of Collateral Agent and the Secured Parties
shall continue as if no such proceeding had been instituted.

         Section 14. Collateral Agent.  Collateral Agent has been appointed as
collateral agent pursuant to the Credit Agreement.  The actions of Collateral
Agent hereunder are subject to the provisions of the Credit Agreement.
Collateral Agent shall have the right hereunder to make demands, to give
notices, to exercise or refrain from exercising any rights, and  to take or
refrain from taking action (including, without limitation, the release or
substitution of Pledged Collateral), in accordance with this Agreement and the
Credit Agreement.  Collateral Agent may resign and a successor Collateral Agent
may be appointed in the manner provided in the Credit Agreement; provided,
however, that at the time of appointment of a successor Collateral Agent, if
Collateral Agent, through its possession, control, or ownership of Pledged
Collateral or otherwise, holds, owns, or controls any Governmental License
issued by the FCC such that the FCC must consent to the appointment of a
successor Collateral Agent, until the FCC has consented to the appointment of a
successor Collateral Agent the Collateral Agent shall retain control over such
Pledged Collateral or Government Licenses.  Upon the acceptance of any
appointment as Collateral Agent by a successor Collateral Agent, that successor
Collateral Agent

<PAGE>   241

shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Collateral Agent under this Agreement,
and the retiring Collateral Agent shall thereupon be discharged from its duties
and obligations under this Agreement. After any retiring Collateral Agent's
resignation, the provisions of this Agreement shall inure to its benefit as to
any actions taken or omitted to be taken by it under this Agreement while it
was Collateral Agent.

         Section 15. Collateral Agent May Perform; Collateral Agent Appointed
Attorney-in-Fact.  If the Pledgor shall fail to do any act or thing that it has
covenanted to do hereunder or any warranty on the part of such Pledgor
contained herein shall be breached, Collateral Agent or any Secured Party may
(but shall not be obligated to), subject to the provisions of Section 29 of
this Agreement, do the same or cause it to be done or remedy any such breach,
and may expend funds for such purpose.  Any and all amounts so expended by
Collateral Agent or such Secured Party shall be paid by such Pledgor promptly
upon demand therefor, with interest at the highest rate then in effect under
the Credit Agreement during the period from and including the date on which
such funds were so expended to the date of repayment.  The Pledgor's
obligations under this Section 15 shall survive the termination of this
Agreement and the discharge of such Pledgor's other obligations under this
Agreement, the Credit Agreement and any other Credit Document.  The Pledgor
hereby appoints Collateral Agent its attorney-in-fact with an interest, with
full authority in the place and stead of such Pledgor and in the name of such
Pledgor, or otherwise, from time to time in Collateral Agent's discretion to
take any action and to execute any instrument consistent with the terms  of
this Agreement and the other Credit Documents which the Collateral Agent may
deem necessary or advisable to accomplish the purposes of this Agreement except
that with respect to any FCC applications or filings or other action subject to
FCC rules, regulations and policies, Collateral Agent shall serve as
attorney-in-fact only to the extent permitted under the Communications Act and
FCC rules, regulations and policies.  The foregoing grant of authority is a
power of attorney coupled with an interest and such appointment shall be
irrevocable for the term of this Agreement.  The Pledgor hereby ratifies all
that such attorney shall lawfully do or cause to be done by virtue hereof.

<PAGE>   242

         Section 16. Indemnity.

         (a) Indemnity.  The Pledgor agrees to indemnify, pay and hold harmless
Collateral Agent and each of the Secured Parties and the officers, directors,
employees, agents and affiliates of Collateral Agent and each of the Secured
Parties (collectively called the "Indemnitees") from and against any and all
other liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, claims, costs (including, without limitation, settlement costs),
expenses or disbursements of any kind or nature whatsoever (including, without
limitation, the reasonable fees and disbursements of counsel for such
Indemnitees in connection with any investigative, administrative or judicial
proceeding commenced or threatened, whether or not such Indemnitee shall be
designated a party thereto), which may be imposed on, incurred by, or asserted
against that Indemnitee, in any manner relating to or arising out of this
Agreement or any other Credit Document (including, without limitation, any
misrepresentation by the Pledgor in this Agreement or any other Credit
Document) (the "indemnified liabilities"); provided that the Pledgors shall not
have any obligation to an Indemnitee hereunder with respect to indemnified
liabilities if it has been determined by a final decision (after all appeals
and the expiration of time to appeal) by a court of competent jurisdiction that
such indemnified liability arose from the gross negligence or willful
misconduct of that Indemnitee.  To the extent that the undertaking to
indemnify, pay and hold harmless set forth in the preceding sentence may be
unenforceable because it is violative of any law or public policy, each Pledgor
shall contribute the maximum portion which it is permitted to pay and satisfy
under applicable law, to the payment and satisfaction of all indemnified
liabilities incurred by the Indemnitees or any of them.

         (b) Survival.  The obligations of each Pledgor contained in this
Section 16 shall survive the termination of this Agreement and the discharge of
each Pledgor's other obligations under this Agreement and under the other
Credit Documents.

         (c) Reimbursement.  Any amounts paid by any Indemnitee as to which
such Indemnitee has the right to

<PAGE>   243

reimbursement shall constitute Secured Obligations secured by the Pledged
Collateral.

         Section 17. Modification in Writing.  No amendment, modification,
supplement, termination or waiver of or to any provision of this Agreement, nor
consent to any departure by the Pledgor therefrom, shall be effective unless
the same shall be done in accordance with the terms of the Credit Agreement and
unless in writing and signed by Collateral Agent and Pledgor.  Any amendment,
modification or supplement of or to any provision of this Agreement, any waiver
of any provision of this Agreement, and any consent to any departure by the
Pledgor from the terms of any provision of this Agreement, shall be effective
only in the specific instance and for the specific purpose for which made or
given.  Except where notice is specifically required by this Agreement or any
other Credit Document, no notice to or demand on the Pledgor in any case shall
entitle any such Pledgor to any other or further notice or demand in similar or
other circumstances.

         Section 18. Termination; Release.  When all the Secured Obligations
have been indefeasibly paid in full and the Commitments of the Banks to make
any Loan under the Credit Agreement shall have expired, this Agreement shall
terminate.  Upon termination of this Agreement or any release of Pledged
Collateral in accordance with the provisions of the Credit Agreement,
Collateral Agent shall, upon the request and at the sole cost and expense of
the applicable Pledgor, forthwith assign, transfer and deliver to such Pledgor,
against receipt and without recourse to or warranty by Collateral Agent, such
of the Pledged Collateral to be released (in the case of a release) as may be
in the possession of Collateral Agent and as shall not have been sold or
otherwise applied pursuant to the terms hereof, on the order of and at the sole
cost and expense of such Pledgor, and proper instruments (including UCC
termination statements on Form UCC-3) acknowledging the termination of this
Agreement or the release of such Pledged Collateral, as the case may be.

         Section 19. Notices.  Unless otherwise provided herein or in the
Credit Agreement, any notice or other communication herein required or
permitted to be given shall be given in the manner set forth in the Credit
Agreement;

<PAGE>   244

provided that notices to Collateral Agent shall not be effective until received
by Collateral Agent.

         Section 20. Continuing Security Interest; Assignment.  This Agreement
shall create a continuing security interest in the Pledged Collateral and shall
(i) be binding upon each Pledgor, its respective successors and assigns, and
(ii) inure, together with the rights and remedies of Collateral Agent
hereunder, to the benefit of Collateral Agent and the other Secured Parties and
each of their respective successors, transferees and assigns; no other Persons
(including, without limitation, any other creditor of the Pledgor) shall have
any interest herein or any right or benefit with respect hereto.  Without
limiting the generality of the foregoing clause (ii), any Bank may assign or
otherwise transfer any indebtedness held by it secured by this Agreement to any
other Person, and such other Person shall thereupon become vested with all the
benefits in respect thereof granted to such Bank, herein or otherwise, subject
however, to the provisions of the Credit Agreement.

         Section 21. GOVERNING LAW; TERMS.  THIS AGREEMENT SHALL BE GOVERNED
BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS, EXCEPT TO
THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST HEREUNDER,
OR REMEDIES HEREUNDER, IN RESPECT OF ANY PLEDGED COLLATERAL ARE GOVERNED BY THE
LAWS OF A JURISDICTION OTHER THAN THE STATE OF NEW YORK.

         Section 22. CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  ALL
JUDICIAL PROCEEDINGS BROUGHT AGAINST THE PLEDGOR WITH RESPECT TO THIS AGREEMENT
MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE
STATE OF NEW YORK AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT THE PLEDGOR
ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND
UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS, AND
IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION
WITH THIS AGREEMENT.  THE PLEDGOR DESIGNATES AND APPOINTS AMERICAN TELECASTING,
INC., WITH AN ADDRESS AT 5575 TECH CENTER DRIVE, SUITE 300, COLORADO SPRINGS,
COLORADO 80919, AND SUCH OTHER PERSONS AS MAY HEREAFTER BE SELECTED BY THE
PLEDGOR IRREVOCABLY  AGREEING IN WRITING TO SO SERVE, AS ITS AGENT TO RECEIVE
ON ITS BEHALF, SERVICE OF ALL PROCESS IN ANY

<PAGE>   245

SUCH PROCEEDINGS IN ANY SUCH COURT, SUCH SERVICE BEING HEREBY ACKNOWLEDGED BY
THE PLEDGOR TO BE EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT.  A COPY OF
SUCH PROCESS SO SERVED SHALL BE MAILED BY REGISTERED MAIL TO THE PLEDGOR AT ITS
ADDRESS PROVIDED FOR IN SECTION 19 HEREOF EXCEPT THAT UNLESS OTHERWISE PROVIDED
BY APPLICABLE LAW, ANY FAILURE TO MAIL SUCH COPY SHALL NOT AFFECT THE VALIDITY
OF SERVICE OF PROCESS.  IF ANY AGENT APPOINTED BY THE PLEDGOR REFUSES TO
RECEIVE AND FORWARD SUCH SERVICE, THE PLEDGOR HEREBY AGREES THAT SERVICE UPON
IT BY MAIL SHALL CONSTITUTE SUFFICIENT NOTICE.  NOTHING HEREIN SHALL AFFECT THE
RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE
RIGHT OF COLLATERAL AGENT TO BRING PROCEEDINGS AGAINST PLEDGOR IN THE COURTS OF
ANY OTHER JURISDICTION.

         Section 23. Severability of Provisions.  Any provision of this
Agreement which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

         Section 24. Execution in Counterparts.  This Agreement and any
amendments, waivers, consents or supplements hereto may be executed in any
number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed to
be an original, but all such counterparts together shall constitute one and the
same agreement.

         Section 25. Headings.  The Section headings used in this Agreement are
for convenience of reference only and shall not affect the construction of this
Agreement.

         Section 26. Obligations Absolute.  All obligations of the Pledgor
hereunder shall be absolute and unconditional irrespective of:

         (i) any bankruptcy, insolvency, reorganization, arrangement,
    readjustment, composition, liquidation or the like of the Pledgor or any
    other Credit Party;

<PAGE>   246

         (ii)    any lack of validity or enforceability of the Credit
    Agreement, the Guarantee or any other Credit Document or any other
    agreement or instrument relating thereto;

         (iii)   any change in the time, manner or place of payment of, or in
    any other term of, all or any of the Secured Obligations, or any other
    amendment or waiver of or any consent to any departure from the Credit
    Agreement, the Guarantee, any other Credit Document or any other agreement
    or instrument relating thereto;

         (iv)    any exchange, release or non-perfection of any other
    collateral, or any release or amendment or waiver of or consent to any
    departure from any guarantee, for all or any of the Secured Obligations;

         (v)     any exercise or non-exercise, or any waiver of any right,
    remedy, power or privilege under or in respect of this Agreement, the
    Guarantee or any other Credit Document except as specifically set forth in
    a waiver granted pursuant to the provisions of Section 17 hereof; or

         (vi)    any other circumstances which might otherwise constitute a
    defense available to, or a discharge of, any other Pledgor.

         Section 27. Collateral Agent's Right to Sever Indebtedness.

         (a) The Pledgor acknowledges that (i) the Pledged Collateral does not
constitute the sole source of security for the payment and performance of the
Secured Obligations and that the Secured Obligations are also secured by other
types of property of such Pledgor and its Affiliates in other jurisdictions
(all such property, collectively, the " "), (ii) the number of such
jurisdictions and the nature of the transaction of which this instrument is a
part are such that it would have been impracticable for the parties to allocate
to each item of Collateral a specific loan amount and to

<PAGE>   247

execute in respect of such item a separate credit agreement, and (iii) each
Pledgor intends that Collateral Agent have the same rights with respect to the
Pledged Collateral, in any judicial proceeding relating to the exercise of any
right or remedy hereunder or otherwise, that Collateral Agent would have had if
each item of collateral had been pledged or encumbered pursuant to a separate
credit agreement and security instrument.  In furtherance of such intent, each
Pledgor agrees to the greatest extent permitted by law that Collateral Agent
may at any time  by notice (an "Allocation Notice") to the Pledgor allocate a
portion of the Secured Obligations (the "Allocated Indebtedness") to the
Pledged Collateral of such Pledgor and sever from the remaining Secured
Obligations the Allocated Indebtedness.  From and after the giving of an
Allocation Notice with respect to the Pledged Collateral, the Secured
Obligations hereunder shall be limited to the extent set forth in the
Allocation Notice and (as so limited) shall, for all purposes, be construed as
a separate credit obligation of each Pledgor unrelated to the other
transactions contemplated by the Credit Agreement or any other Credit Document
or any document related to either thereof.  To the extent that the proceeds of
any judicial proceeding relating to the exercise of any right or remedy
hereunder of the Pledged Collateral shall exceed the Allocated Indebtedness,
such proceeds shall belong to such Pledgor and shall not be available hereunder
to satisfy any Secured Obligations of such Pledgor other than the Allocated
Indebtedness.  In any action or proceeding to exercise any right or remedy
under this Agreement which is commenced after the giving by Collateral Agent of
an Allocation Notice, the Allocation Notice shall be conclusive proof of the
limits of the Secured Obligations hereby secured, and the Pledgor may
introduce, by way of defense or counterclaim, evidence thereof in any such
action or proceeding.  Notwithstanding any provision of this Section 27, the
proceeds received by Collateral Agent pursuant to this Agreement shall be
applied by Collateral Agent in accordance with the provisions of Section 11
hereof.

         (b) The Pledgor hereby waives to the greatest extent permitted under
law the right to a discharge of any of the Secured Obligations under any
statute or rule of law now or hereafter in effect which provides that the
exercise of any particular right or

<PAGE>   248

remedy as provided for herein (by judicial proceedings or otherwise)
constitutes the exclusive means for satisfaction of the Secured Obligations or
which makes unavailable any further judgment or any other right or remedy
provided for herein because Collateral Agent elected to proceed with the
exercise of such initial right or remedy or because of any failure by
Collateral Agent to comply with laws that prescribe conditions to the
entitlement to such subsequent judgment or the availability of such subsequent
right or remedy.  In the event that, notwithstanding the foregoing waiver, any
court shall for any reason hold that such subsequent judgment or action is not
available to Collateral Agent, no Pledgor shall (i) introduce in any other
jurisdiction any judgment so holding as a defense to enforcement against such
Pledgor of any remedy in the Credit Agreement, the Guarantee or any other
agreement  or instrument executed in connection with the Credit Agreement or
(ii) seek to have such judgment recognized or entered in any other
jurisdiction, and any such judgment shall in all events be limited in
application only to the state or jurisdiction where rendered and only with
respect to the collateral referred to in such judgment.

         (c) In the event any instrument in addition to the Allocation Notice
is necessary to effectuate the provisions of this Section 27, including,
without limitation, any amendment to this Agreement, any substitute promissory
note or affidavit or certificate of any kind, Collateral Agent may execute and
deliver such instrument as the attorney-in-fact of the Pledgor.

         (d) Notwithstanding anything set forth herein to the contrary, the
provisions of this Section 27 shall be effective only to the maximum extent
permitted by law.

         Section 28. Future Advances.  This Agreement shall secure the payment
of any amounts advanced from time to time pursuant to the Credit Agreement.

         Section 29. Facilitating Governmental Approvals; Specific Performance.

         (a) In connection with the exercise by Collateral Agent of its rights
under this Agreement relating to the disposition of the Pledged Collateral as
it may affect the control of any Governmental License issued by the FCC or any
other authorizations, agreements, permits, licenses, and

<PAGE>   249

franchises of the Pledgor, it may be necessary to obtain the prior consent or
approval of the FCC or other Governmental Authority to the exercise of
Collateral Agent's rights with respect to the Pledged Collateral.  To the
extent that any such consent or approval is required for any action that
Collateral Agent may take under this Agreement with respect to the Pledged
Collateral, receipt of such FCC or Governmental Authority approval shall be a
condition precedent to Collateral Agent's exercise of such rights.  In
furtherance of the first sentence of this Section, the Pledgor hereby agrees,
at its own cost, to use its best efforts to take any and all actions which
Collateral Agent may request in order to obtain such consents or approvals or
any other governmental authorization as may be necessary to enable Collateral
Agent to exercise and enjoy the full rights and benefits granted to it under
this Agreement, the Credit Agreement, or any other Credit Document, including,
without limitation, the preparation, execution, delivery or filing on  the
Pledgor's behalf and in such Pledgor's name, or in such other name as may be
appropriate or required, or causing to be prepared, executed, delivered or
filed, all applications, certificates, filings, instruments, information,
reports and other documents (including, without limitation, any application for
any assignment or transfer of control or ownership).

         (b) The Pledgor hereby acknowledges that a breach of any of its
respective obligations contained in this Agreement will cause irreparable
injury to Collateral Agent, and that such a breach would not be adequately
compensable in damages, and therefore Pledgors agree that their obligations
under this Agreement shall be specifically enforceable.

         all Proceeds (as hereinafter defined) of any and all of the foregoing.

         Secured Obligations.  This Agreement secures, and the Pledged
Collateral is collateral security for, the payment and performance in full when
due, whether at stated maturity, by acceleration or otherwise (including,
without limitation, the payment of interest and other amounts which would

any liability on Collateral Agent or any Secured Party for any act or omission
on the part of Pledgors relating thereto or for any breach of any
representation or warranty on the part of Pledgors contained in this Agreement
or any other Credit Document, or under or in respect of the Pledged Collateral
or made in connection herewith or therewith.  The obligations of Pledgors
contained in this Section 3 shall survive the termination of this Agreement and
the discharge of Pledgors' other obligations under this Agreement or the other
Credit Documents.

         Supplements by Collateral Agent.  Pledgors hereby authorize Collateral
Agent, without relieving Pledgors of any obligations hereunder, to file
financing statements, continuation statements, amendments thereto and other
documents relative to all or any part thereof, without the signature of
Pledgors where permitted by law, and Pledgors agree to do such further acts and
things, and to execute and deliver to Collateral Agent such additional
assignments, agreements, powers and instruments, as Collateral Agent may deem
necessary or appropriate, wherever required or permitted by law in order to
perfect and preserve the rights and interests granted to Collateral Agent
hereunder or to carry into effect the purposes of this Agreement or better to
assure and confirm unto Collateral Agent its respective rights, powers and
remedies hereunder.  All of the foregoing shall be at the sole cost and expense
of Pledgors.

         Representations, Warranties and Covenants.  Pledgors represent,
warrant and covenant as follows:

         Necessary Filings.  Upon the filing of financing statements and
    acceptance thereof in the appropriate offices under the UCC, the security
    interest granted to Collateral Agent for the benefit of the Secured Parties
    pursuant to this Agreement in and to the Pledged Collateral will constitute
    a perfected security interest therein, superior and prior to the rights of
    all other Persons therein and subject to no Liens other than the Liens
    identified on Schedule A relating to the items of Pledged Collateral
    identified on such schedule (collectively, "Prior Liens").

         No Liens.  Pledgors are as of the date hereof, and, as to Pledged
    Collateral acquired by them from time to time after the date hereof,
    Pledgors will be, the owner of all Pledged Collateral free from any Lien or
    other right, title or interest of any Person other than (i) Prior Liens,
    (ii) the Lien and security interest created by this Agreement, (iii) Liens
    of the type described in clauses (a), (b), (c), (d), (i) and (j) of the
    definition of Permitted Encumbrances and (iv) Liens for taxes being
    contested in accordance with the Credit Agreement, and Pledgors shall
    defend the Pledged Collateral against all claims and demands of all Persons
    at any time claiming any interest therein adverse to Collateral Agent or
    any Secured Party.

         Other Financing Statements.  There is no financing statement (or
    similar statement or instrument of registration under the law of any
    jurisdiction) covering or purporting to cover any interest of any kind in
    the Pledged Collateral other than financing statements relating to (i)
    Prior Liens, (ii) this Agreement and (iii) Liens of the type described in
    clauses (a), (b), (c), (d), (i) and (j) of the definition of Permitted
    Encumbrances and so long as any of the Secured Obligations remain unpaid or
    the Commitments of the Banks to make any Loan shall not have expired or
    been sooner terminated, Pledgors shall not execute, authorize or permit to
    be filed in any public office any financing statement (or similar statement
    or instrument of registration under the law of any jurisdiction) or
    statements relating to the Pledged Collateral, except, in each case,
    financing statements filed or to be filed in respect of and covering the

    its terms except as such enforceability may be limited by bankruptcy,
    insolvency, reorganization, moratorium or similar laws relating to or
    limiting creditors' rights generally or by equitable principles relating to
    enforceability.

         No Consents, etc.  Except as set forth in Part_B of Schedule D hereto,
    no consent of any party (including, without limitation, stockholders or
    creditors of Pledgors or any account debtor under a Receivable) and, except
    as provided in Section 30 of this Agreement, no consent, authorization,
    approval, license or other action by, and no notice to or filing with, any
    Governmental Authority or regulatory body or other Person is required for
    (x) the pledge by Pledgors of the Pledged Collateral pursuant to this
    Agreement or for the execution, delivery or performance of this Agreement
    by Pledgors, (y) the exercise by Collateral Agent of the rights provided
    for in this Agreement, or (z) the exercise by Collateral Agent of the
    remedies in respect of the Pledged Collateral pursuant to this Agreement
    other than internal consents of the Collateral Agent.

         Pledged Collateral.  All information set forth herein, including the
    Schedules annexed hereto, and all information contained in any documents,
    schedules and lists heretofore delivered to any Secured Party in connection
    with this Agreement, in each case, relating to the Pledged Collateral is
    accurate and complete in all material respects.

         System Agreements.  The System Agreements listed on Schedule D hereto
    are all of the System Agreements the Pledgors and ATel have entered into

    been delivered to the Banks and are true and correct copies thereof.
    Except as to matters which would not, individually or in the aggregate,
    materially diminish the value of any Market, the System Agreements are in
    full force and effect, have not been amended or modified except as
    disclosed on Schedule D hereto, have not been assigned by any Pledgor, and

    or received any notice of default thereunder and to the best knowledge of
    Pledgors no event has occurred as of the date hereof which with the passage
    of time or the giving of notice, or both, would constitute a default
    thereunder as of the date hereof.  Each Pledgor shall perform and observe
    (except as otherwise provided by law) each term and provision of each
    System Agreement and maintain each System Agreement in full force and
    effect except in the ordinary course of business consistent with past
    practice and to the extent such actions would not have a Material Adverse
    Effect.

         No Amendments.  Except as permitted by Section 6.10 of the Credit
    Agreement, each Pledgor agrees that no amendment or modification of any
    material term of any System Agreement shall be effective without the prior
    written consent of Collateral Agent.  Each Pledgor further agrees that, so
    long as this Agreement is in effect, such Pledgor will not terminate any
    System Agreement and will not assign, sell, pledge, mortgage or otherwise
    transfer or encumber its interest in any System Agreement except in the
    ordinary course of business consistent with past practice and to the extent
    such actions would not have a Material Adverse Effect.

         No Defaults.  Neither the execution nor the delivery of this Agreement
    constitutes the basis for a default under any System Agreement.

         Notices.  Each Pledgor shall notify Collateral Agent in the event it
    receives any material notice or communication with respect to any System
    Agreement, including, without limitation, notices of default, and shall
    promptly forward copies of any such communications to Collateral Agent.

         Default Under System Agreements.  To the extent permitted under the
    terms of any System Agreement and the terms of the written consent of the
    lessor under any such System Agreement, in the event of a default by any
    Pledgor under any System Agreement, the lessor under such agreement shall
    permit Collateral Agent to cure such

    default and thereafter perform any of such Pledgor's obligations under such
    System Agreement, and such performance by Collateral Agent will not
    constitute a default under such System Agreement.

         Governmental Licenses.  Except as to matters which would not,
    individually or in the aggregate, materially diminish the value of any
    Market, the Governmental Licenses listed on Schedule E hereto are all of
    the Governmental Licenses each Pledgor holds, leases or subleases in
    connection with the operation of its System on the date hereof.  All such
    Governmental Licenses are validly existing and in full force and effect
    under the Communications Act and any other statutes, laws, and regulations
    pursuant to which the Governmental Licenses have been issued, including the
    rules and regulations of the FCC.  There is not now pending, or to the
    knowledge of any Pledgor is there threatened, any action by or before any
    governmental agency or entity, including the FCC, to revoke or materially
    and adversely modify any of such Governmental Licenses issued to such
    Pledgor, and such Pledgor is in substantial compliance with said
    Governmental Licenses.  There are not, or to the knowledge of any Pledgor
    threatened, any notice of violation, notice of apparent liability or of
    forfeiture or material complaint against such Pledgor in connection with
    the System, except as incurred in the ordinary course of business and would
    not have a Material Adverse Effect.

         Special Provisions Concerning Receivables.

         Special Representations and Warranties.  As of the time when each of
    its Receivables arises, each Pledgor shall be deemed to have represented
    and warranted that such Receivable and all records, papers and documents
    relating thereto to such Pledgor's knowledge (i) are genuine and correct
    and in all respects what they purport to be, (ii) represent the legal,
    valid and binding obligation of the account debtor, evidencing indebtedness
    unpaid and owed by such account debtor, arising out of the performance of
    labor or services or the sale or lease and delivery of the merchandise
    listed therein or out of an advance or a loan, (iii) will, in the case of a

    Receivable, except for the original or duplicate original invoice sent to a
    purchaser evidencing such purchaser's account, be the only original
    writings evidencing and embodying such obligation of the account debtor
    named therein, (iv) constitute and evidence true and valid obligations,
    enforceable in accordance with their respective terms, not subject to any
    defenses, set-offs or counterclaims except with respect to refunds, returns
    and allowances in the ordinary course of business, or stamp or other taxes,
    and (v) are in compliance and conform with all applicable federal, state
    and local laws and applicable laws of any relevant foreign jurisdiction.

         Maintenance of Records.  Pledgors shall keep and maintain at their own
    cost and expense complete records of each Receivable, in a manner
    consistent with prudent business practice, including, without limitation,
    records of all payments received, all credits granted thereon, all
    merchandise returned and all other documentation relating thereto, and
    Pledgors shall make the same available to Collateral Agent or any Secured
    Party for inspection upon reasonable prior notice to such Pledgors, at such
    times during normal business hours as Collateral Agent or an Secured Party
    may request.  Pledgors shall, at Pledgors' sole cost and expense, upon
    Collateral Agent's demand made at any time after the occurrence of an Event
    of Default, deliver all tangible evidence of Receivables, including,
    without limitation, all documents evidencing Receivables and any books and
    records relating thereto to Collateral Agent or to its representatives
    (copies of which evidence and books and records may be retained by
    Pledgors).  Upon the occurrence of an Event of Default, Collateral Agent
    may transfer a full and complete copy of each Pledgor's books, records,
    credit information, reports, memoranda and all other writings relating to
    the Receivables to and for the use by any Person that has acquired or is
    contemplating acquisition of an interest in the Receivables or Collateral
    Agent's security interest therein without the consent of such Pledgor;
    provided that, to the extent any such document is subject to a
    confidentiality agreement, Collateral Agent shall not transfer such
    document unless such Person executes a confidentiality agreement in a form
    satisfactory to the Collateral Agent.

         Legend.  Pledgors shall legend, at the request of Collateral Agent
    made at any time after the occurrence of an Event of Default and in form
    and manner satisfactory to Collateral Agent, the Receivables and other
    books, records and documents of Pledgors evidencing or pertaining to the
    Receivables with an appropriate reference to the fact that the Receivables
    have been assigned to Collateral Agent for the benefit of the Secured
    Parties and that Collateral Agent has a security interest therein.

         Modification of Terms, etc.  Pledgors shall not rescind or cancel any
    indebtedness evidenced by any Receivable or modify any term thereof or make
    any adjustment with respect thereto except in the ordinary course of
    business consistent with past business practice, or extend or renew any
    such indebtedness except in the ordinary course of business consistent with
    past business practice or compromise or settle any material dispute, claim,
    suit or legal proceeding relating thereto or sell any Receivable or
    interest therein without the prior written consent of Collateral Agent.
    Pledgors shall timely fulfill all material obligations on their part to be
    fulfilled under or in connection with the Receivables.

         Collection.  Pledgors shall cause to be collected from the account
    debtor of each of the Receivables, as and when due (including, without
    limitation, Receivables that are delinquent, such Receivables to be
    collected in accordance with generally accepted commercial collection
    procedures), any and all amounts owing under or on account of such
    Receivable, and apply forthwith upon receipt thereof all such amounts as
    are so collected to the outstanding balance of such Receivable, except that
    Pledgors may, with respect to a Receivable, allow in the ordinary course of
    business (i) a refund or credit due as a result of returned or damaged or
    defective merchandise and (ii) such extensions of time to pay amounts due
    in respect of Receivables and such other modifications of payment terms or
    settlements in respect of Receivables as shall be commercially reasonable
    in the circumstances, all in accordance with Pledgors' ordinary course of
    business consistent with their collection practices as in effect from time
    to time.  The costs and expenses (including, without limitation, attorneys'
    fees) of collection, in any

    case, whether incurred by Pledgors, Collateral Agent or any Secured Party,
    shall be paid by Pledgors.

         Instruments.  Pledgors shall deliver to Collateral Agent, within five
    days after receipt thereof by Pledgors, any Instrument evidencing
    Receivables which is in the principal amount of $25,000 or more.  Any
    Instrument delivered to Collateral Agent pursuant to this Section 6(f)
    shall be appropriately endorsed (if applicable) to the order of Collateral
    Agent, as agent for the Secured Parties, and shall be held by Collateral
    Agent as further security hereunder.

         Cash Collateral.  Upon the occurrence of an Event of Default, if
    Collateral Agent so directs, Pledgors shall cause all payments on account
    of the Receivables to be held by Collateral Agent as cash collateral, upon
    acceleration or otherwise.  Without notice to or assent by Pledgors,
    Collateral Agent may apply any or all amounts then or thereafter held as
    cash collateral in the manner provided in Section 11.  The costs and
    expenses (including, without limitation, reasonable attorneys' fees) of
    collection, whether incurred by Collateral Agent or any Secured Party,
    shall be paid by Pledgors.

         Provisions Concerning All Pledged Collateral.

         Protection of Collateral Agent's Security.  Pledgors shall not take
    any action that impairs the rights of Collateral Agent or any Secured Party
    in the Pledged Collateral.  Pledgors shall at all times keep the Inventory
    and Equipment insured, at Pledgors' own expense, to Collateral Agent's
    reasonable satisfaction against fire, theft and all other risks to which
    the Pledged Collateral may be subject, in such amounts and with such
    deductibles as would be maintained by operators of businesses similar to
    the business of Pledgors or as Collateral Agent may otherwise reasonably
    require.  Each policy or certificate with respect to such insurance shall
    be endorsed to Collateral Agent's satisfaction for the benefit of
    Collateral Agent (including, without limitation, by naming Collateral Agent
    as an additional





______________________________________

    named insured and sole loss payee as Collateral Agent may request) and such
    policy or certificate shall be delivered to Collateral Agent.  Each such
    policy or certificate shall state that such policy cannot be cancelled
    without 30 days' prior written notice to Collateral Agent.  At least 30
    days prior to the expiration of any such policy of insurance, Pledgors
    shall deliver to Collateral Agent an extension or renewal policy or an
    insurance certificate evidencing renewal or extension of such policy.  If
    Pledgors shall fail to insure such Pledged Collateral to Collateral Agent's
    reasonable satisfaction, Collateral Agent shall have the right (but shall
    be under no obligation) to advance funds to procure or renew or extend such
    insurance and Pledgors agree to reimburse Collateral Agent for all costs
    and expenses thereof, with interest on all such funds from the date
    advanced until paid in full at the highest rate then in effect under the
    Credit Agreement.

         Insurance Proceeds.  Upon the occurrence and during the continuance of
    an Event of Default, Collateral Agent shall have the option to apply any
    proceeds of insurance received by it pursuant to this Agreement toward the
    payment of the Secured Obligations in accordance with Section 11 hereof or
    to continue to hold such proceeds as additional collateral to secure the
    performance by each Pledgor of the Secured Obligations.  So long as no
    Event of Default shall have occurred and be continuing, each Pledgor shall
    have the option (i) to direct Collateral Agent to apply any proceeds of
    insurance received by it toward payment of the Secured Obligations in
    accordance with Section 11 hereof or (ii) to elect, by delivery of written
    notice to Collateral Agent, to apply the proceeds of such insurance to the
    repair or replacement of the item or items of Pledged Collateral in respect
    of which such proceeds were received.  In the event that any Pledgor elects
    to apply such proceeds to the repair or replacement of any item of Pledged
    Collateral pursuant to clause (ii) of the preceding sentence, Collateral
    Agent shall release such proceeds as soon as practicable following its
    receipt of such Pledgor's written notice of such election.  Such Pledgor
    shall upon its receipt of such proceeds promptly commence and diligently
    continue to perform such repair or promptly effect such replacement.

                                      -16-

         Maintenance of Equipment.  Each Pledgor shall cause the Equipment to
    be operated in compliance with all applicable FCC requirements and
    maintained and preserved in the same condition, repair and working order as
    when new, ordinary wear and tear excepted, and to the extent consistent
    with current business practice in accordance with any manufacturer's
    manual, and shall forthwith, or in the case of any loss or damage which
    (individually or in the aggregate) exceeds $100,000 to any of the Equipment
    (of which prompt notice shall be given to Collateral Agent) as quickly as
    commercially practicable after the occurrence thereof, make or cause to be
    made all repairs, replacements and other improvements in connection
    therewith which are necessary or desirable to such end.

         Payment of Taxes; Claims.  Pledgors shall pay promptly when due all
    property and other taxes, assessments and governmental charges or levies
    imposed upon, and all claims (including claims for labor, materials and
    supplies) against, the Pledged Collateral including all fees assessed or
    imposed by the FCC; provided, that, no such tax, assessment, charge, levy
    or claim shall be required to be paid to the extent that it is being
    diligently contested in good faith and by appropriate proceedings.
    Notwithstanding the foregoing, Pledgors may at their own expense contest
    the amount or applicability of any of the obligations described in the
    preceding sentence by appropriate legal or administrative proceedings,
    prosecution of which operates to prevent the collection thereof and the
    sale or forfeiture of the Pledged Collateral or any part thereof to satisfy
    the same; provided, however, that in connection with such contest, Pledgors
    shall have made provision for the payment of such contested amount on
    Pledgors' books if and to the extent required by generally accepted
    accounting principles.

         Further Actions.  Pledgors shall, at their sole cost and expense,
    make, execute, endorse, acknowledge, file or refile and/or deliver to
    Collateral Agent from time to time such lists, descriptions and
    designations of the Pledged Collateral, copies of warehouse receipts,
    receipts in the nature of warehouse receipts, bills of lading, documents of
    title, vouchers, invoices, schedules,

    confirmatory assignments, supplements, additional security agreements,
    conveyances, financing statements, transfer endorsements, powers of
    attorney, certificates, reports and other assurances or instruments and
    take such further steps relating to the Pledged Collateral and other
    property or rights covered by the security interest hereby granted, which
    Collateral Agent deems reasonably appropriate or advisable to exercise and
    enforce its rights and remedies hereunder with respect to any Pledged
    Collateral and to perfect, preserve or protect the security interest in the
    Pledged Collateral created and granted by this Agreement.

         Financing Statements.  Pledgors shall sign and deliver to Collateral
    Agent such financing and continuation statements, in form acceptable to
    Collateral Agent, as may from time to time be required to continue and
    maintain a valid, enforceable, first priority security interest in the
    Pledged Collateral as are to the extent provided herein and the other
    rights, as against third parties, provided hereby, all in accordance with
    the UCC as enacted in any and all relevant jurisdictions or any other
    relevant law.  Pledgors shall pay any applicable filing fees and other
    expenses related to the filing of such financing and continuation
    statements.  Pledgors authorize Collateral Agent to file any such financing
    or continuation statements without the signature of Pledgors where
    permitted by law.

         Warehouse Receipts Non-Negotiable.  If any warehouse receipt or
    receipt in the nature of a warehouse receipt is issued with respect to any
    of the Inventory, Pledgors shall not permit such warehouse receipt or
    receipt in the nature thereof to be "negotiable" (as such term is used in
    Section 7-104 of the UCC or under other relevant law).

         Transfers and Other Liens.  Pledgors shall not (a) sell, convey,
assign or otherwise dispose of, or grant any option with respect to, any of the
Pledged Collateral except as permitted by the Credit Agreement or (b) create or
permit to exist any Lien upon or with respect to any of the Pledged Collateral
other than (i) Prior Liens, (ii) the Lien and security interest granted to
Collateral Agent under this

Agreement, (iii) Liens of the type described in clauses (a), (b), (c), (d), (i)
and (j) of the definition of Permitted Encumbrances and (iv) Liens for taxes
being contested in accordance with the Credit Agreement.

         Reasonable Care.  Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Pledged Collateral in
its possession if such Pledged Collateral is accorded treatment substantially
equivalent to that which Collateral Agent, in its individual capacity, accords
its own property, it being understood that Collateral Agent shall not have
responsibility for taking any necessary steps to preserve rights against any
Person with respect to any Pledged Collateral.

         Remedies upon Default; Obtaining the Pledged Collateral upon Event of
Default.  (a)  Subject to any necessary prior or subsequent FCC approval, if an
Event of Default shall have occurred, then and in every such case, Collateral
Agent may:

         Personally, or by agents or attorneys, immediately take possession of
    the Pledged Collateral or any part thereof, from Pledgors or any other
    Person who then has possession of any part thereof with or without notice
    or process of law, and for that purpose may enter upon Pledgors' premises
    where any of the Pledged Collateral is located and remove such Pledged
    Collateral and use in connection with such removal any and all services,
    supplies, aids and other facilities of Pledgors.

         Instruct the obligor or obligors on any agreement, instrument or other
    obligation (including, without limitation, the Receivables, the Contracts
    and the System Agreements) constituting the Pledged Collateral to make any
    payment required by the terms of such instrument or agreement directly to
    Collateral Agent; provided, however, that in the event that any such
    payments are made directly to Pledgors, prior to receipt by any such
    obligor of such instruction, Pledgors shall segregate all amounts received
    pursuant thereto in a separate account and pay the same promptly to
    Collateral Agent.

         Sell, assign or otherwise liquidate, or direct Pledgors to sell,
    assign or otherwise liquidate, any or all investments made in whole or in
    part with the Pledged Collateral or any part thereof, and take possession
    of the proceeds of any such sale, assignment or liquidation.

         Take possession of the Pledged Collateral or any part thereof, by
    directing Pledgors in writing to deliver the same to Collateral Agent at
    any place or places so designated by Collateral Agent, in which event
    Pledgors shall at their own expense:  (A) forthwith cause the same to be
    moved to the place or places designated by Collateral Agent and there
    delivered to Collateral Agent; (B) store and keep any Pledged Collateral so
    delivered to Collateral Agent at such place or places pending further
    action by Collateral Agent; and (C) while the Pledged Collateral shall be
    so stored and kept, provide such security and maintenance services as shall
    be necessary to protect the same and to preserve and maintain them in good
    condition.  Pledgors' obligation to deliver the Pledged Collateral is of
    the essence of this Agreement.  Upon application to a court of equity
    having jurisdiction, Collateral Agent shall be entitled to a decree
    requiring specific performance by Pledgors of such obligation.

         Collateral Agent shall be entitled to the appointment, as a matter of
    right and without giving notice to any Pledgor, of a receiver with respect
    to the Pledged Collateral, without regard to the adequacy or inadequacy of
    any Pledged Collateral for the Secured Obligations or the solvency or
    insolvency of any Person or entity then legally or equitably liable for the
    Secured Obligations or any portion thereof, and each Pledgor does hereby
    irrevocably consent to such appointment.  Any such receiver shall have all
    the usual qualifications, powers and duties of receivers in similar cases,
    including the full power to conduct the business of such Pledgor.

         Subject to the provisions of Section 30 of this Agreement, Collateral
    Agent may assume the rights and obligations under any System Agreement, and
    in connection therewith request that any Pledgor or its subsidiaries
    immediately take all steps and actions necessary for the

    assignment of such System Agreements to Collateral Agent, and such Pledgor
    or its subsidiaries shall immediately take all such steps and actions
    necessary for the effective assignment of such System Agreements to
    Collateral Agent, including, without limitation, the execution of an
    assignment of lease and obtaining the consent of any Persons which is or
    may be required for the assignment of such System Agreements to Collateral
    Agent.  Collateral Agent shall have the right to seek specific performance
    of Pledgors' obligations under this Section 10 in accordance with Section
    30 of this Agreement.

         Remedies; Disposition of the Pledged Collateral.  (i) Upon the
    occurrence of an Event of Default, Collateral Agent may from time to time,
    subject to any necessary prior or subsequent FCC approval, exercise in
    respect of the Pledged Collateral, in addition to other rights and remedies
    provided for herein or otherwise available to it, all the rights and
    remedies of a secured party on default under the UCC, and Collateral Agent
    may also in its sole discretion, without notice except as specified below,
    sell the Pledged Collateral or any part thereof in one or more parcels at
    public or private sale, at any exchange, broker's board or at any of
    Collateral Agent's offices or elsewhere, for cash, on credit or for future
    delivery, and at such price or prices and upon such other terms as
    Collateral Agent may deem commercially reasonable.  Collateral Agent or any
    other Secured Party or any of their respective Affiliates may be the
    purchaser of any or all of the Pledged Collateral at any such sale and
    shall be entitled, for the purpose of bidding and making settlement or
    payment of the purchase price for all or any portion of the Pledged
    Collateral sold at such sale, to use and apply any of the Secured
    Obligations owed to such Person as a credit on account of the purchase
    price of any Pledged Collateral payable by such Person at such sale.  Each
    purchaser at any such sale shall acquire the property sold absolutely free
    from any claim or right on the part of Pledgors, and Pledgors hereby waive,
    to the fullest extent permitted by law, all rights of redemption, stay
    and/or appraisal which it now has or may at any time in the future have
    under any rule of law or statute now existing or hereafter enacted.
    Collateral Agent shall not be obligated to make any sale of Pledged
    Collateral regardless of notice of sale having been given.

    Collateral Agent may adjourn any public or private sale from time to time
    by announcement at the time and place fixed therefor, and such sale may,
    without further notice, be made at the time and place to which it was so
    adjourned.  Pledgors hereby waive, to the fullest extent permitted by law,
    any claims against Collateral Agent arising by reason of the fact that the
    price at which any Pledged Collateral may have been sold at such a private
    sale was less than the price which might have been obtained at a public
    sale, even if Collateral Agent accepts the first offer received and does
    not offer such Pledged Collateral to more than one offeree.

         (ii)    Pledgors acknowledge and agree that, to the extent notice of
sale shall be required by law, five days' notice to Pledgors of the time and
place of any public sale or of the time after which any private sale or other
intended disposition is to take place shall be commercially reasonable
notification of such matters.  No notification need be given to Pledgors if it
has signed, after the occurrence of an Event of Default, a statement renouncing
or modifying any right to notification of sale or other intended disposition.

         Waiver of Notice and Claims.  Pledgors hereby waive, to the fullest
    extent permitted by applicable law, notice or judicial hearing in
    connection with Collateral Agent's taking possession or Collateral Agent's
    disposition of any of the Pledged Collateral, including, without
    limitation, any and all prior notice and hearing for any prejudgment remedy
    or remedies and any such right which Pledgors would otherwise have under
    law, and Pledgors hereby further waive, to the fullest extent permitted by
    applicable law:  (i) all damages occasioned by such taking of possession;
    (ii) all other requirements as to the time, place and terms of sale or
    other requirements with respect to the enforcement of Collateral Agent's
    rights hereunder; and (iii) all rights of redemption, appraisal, valuation,
    stay, extension or moratorium now or hereafter in force under any
    applicable law.  Collateral Agent shall not be liable for any incorrect or
    improper payment made pursuant to this Section 10 in the absence of gross
    negligence or willful misconduct.  Any sale of, or the grant of options to
    purchase, or any other realization upon, any Pledged Collateral shall
    operate to divest all right, title, interest, claim and demand, either at
    law or in equity, of Pledgors therein and thereto, and shall be a perpetual
    bar

    both at law and in equity against Pledgors and against any and all Persons
    claiming or attempting to claim the Pledged Collateral so sold, optioned or
    realized upon, or any part thereof, from, through or under Pledgors.

         Certain Sales of Pledged Collateral.  Pledgors recognize that, by
    reason of certain prohibitions contained in law, rules, regulations or
    orders of any foreign Governmental Authority, Collateral Agent may be
    compelled, with respect to any sale of all or any part of the Pledged
    Collateral, to limit purchasers to those who meet the requirements of such
    foreign Governmental Authority.  Pledgors acknowledge that any such sales
    may be at prices and on terms less favorable to Collateral Agent than those
    obtainable through a public sale without such restrictions, and,
    notwithstanding such circumstances, agrees that any such restricted sale
    shall be deemed to have been made in a commercially reasonable manner.

         Application of Proceeds.  The proceeds received by Collateral Agent in
respect of any sale of, collection from or other realization upon all or any
part of the Pledged Collateral pursuant to the exercise by Collateral Agent of
its remedies as a secured creditor as provided in Section 10 hereof shall be
applied, together with any other sums then held by Collateral Agent pursuant to
this Agreement, promptly by Collateral Agent as follows:

         First, to the payment of all reasonable costs and expenses, fees,
    commissions and taxes of such sale, collection or other realization,
    including, without limitation, reasonable compensation to Collateral Agent
    and its agents and counsel, and all reasonable expenses, liabilities and
    advances made or incurred by Collateral Agent in connection therewith,
    together with interest on each such amount at the highest rate then in
    effect under the Credit Agreement from and after the date such amount is
    due, owing or unpaid until paid in full;

         Second, to the payment of all other costs and expenses of such sale,
    collection or other realization,

    including, without limitation, compensation to the Banks and their agents
    and counsel and all reasonable expenses, liabilities and advances made or
    incurred by the Banks in connection therewith, together with interest on
    each such amount at the highest rate then in effect under the Credit
    Agreement from and after the date such amount is due, owing or unpaid until
    paid in full;

         Third, to the indefeasible payment in full in cash of interest and all
    amounts other than principal under the Credit Agreement at any time and
    from time to time owing by Pledgors under or in connection with the Credit
    Agreement, ratably according to the unpaid amounts thereof, without
    preference or priority of any kind among amounts so due and payable,
    together with interest on each such amount at the highest rate then in
    effect under the Credit Agreement from and after the date such amount is
    due, owing or unpaid until paid in full;

         Fourth, to the indefeasible payment in full in cash of principal at
    any time and from time to time owing by Pledgors under or in connection
    with the Credit Agreement, ratably according to the unpaid amounts thereof,
    without preference or priority of any kind, among amounts of principal so
    due and payable, together with interest on each such amount at the highest
    rate then in effect under the Credit Agreement from and after the date such
    amount is due, owing or unpaid until paid in full; and

         Fifth, to the Pledgors, or their respective successors or assigns, or
    to whomsoever may be lawfully entitled to receive the same or as a court of
    competent jurisdiction may direct, of any surplus then remaining from such
    proceeds.

         Expenses.  Pledgors will upon demand pay to Collateral Agent the
amount of any and all reasonable expenses, including the reasonable fees and
expenses of its counsel and the reasonable fees and expenses of any experts and
agents which Collateral Agent may incur in connection with (i) the collection
of the Secured Obligations, (ii) the enforcement and administration of this
Agreement, (iii) the custody or

preservation of, or the sale of, collection from, or other realization upon,
any of the Pledged Collateral, (iv) the exercise or enforcement of any of the
rights of Collateral Agent or any Secured Party hereunder or (v) the failure by
Pledgors to perform or observe any of the provisions hereof.  All amounts
payable by Pledgors under this Section 12 shall be due upon demand and shall be
part of the Secured Obligations.  Pledgors' obligations under this Section 12
shall survive the termination of this Agreement and the discharge of Pledgors'
other obligations hereunder.

         No Waiver; Cumulative Remedies.  (a) No failure on the part of
Collateral Agent to exercise, no course of dealing with respect to, and no
delay on the part of Collateral Agent 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 hereunder preclude any other or
further exercise thereof or the exercise of any other right, power or remedy.
The remedies herein provided are cumulative and are not exclusive of any
remedies provided by law.

         (b) In the event Collateral Agent shall have instituted any proceeding
to enforce any right, power or remedy under this Agreement by foreclosure,
sale, entry or otherwise, and such proceeding shall have been discontinued or
abandoned for any reason or shall have been determined adversely to Collateral
Agent, then and in every such case, Pledgors, Collateral Agent and each Secured
Party shall be restored to their respective former positions and rights
hereunder with respect to the Pledged Collateral, and all rights, remedies and
powers of Collateral Agent and the Secured Parties shall continue as if no such
proceeding had been instituted.

         Collateral Agent.  Collateral Agent has been appointed as collateral
agent pursuant to the Credit Agreement.  The actions of Collateral Agent
hereunder are subject to the provisions of the Credit Agreement.  Collateral
Agent shall have the right hereunder to make demands, to give notices, to
exercise or refrain from exercising any rights, and to take or refrain from
taking action (including, without limitation, the release or substitution of
Pledged Collateral), in accordance with this Agreement and the Credit
Agreement.  Collateral Agent

may resign and a successor Collateral Agent may be appointed in the manner
provided in the Credit Agreement; provided, however, that at the time of
appointment of a successor Collateral Agent, if Collateral Agent, through its
possession, control, or ownership of Pledged Collateral or otherwise, holds,
owns, or controls any Governmental License issued by the FCC such that the FCC
must consent to the appointment of a successor Collateral Agent, until the FCC
has consented to the appointment of a successor Collateral Agent the Collateral
Agent shall retain control over such Pledged Collateral or Government Licenses.
Upon the acceptance of any appointment as Collateral Agent by a successor
Collateral Agent, that successor Collateral Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Collateral Agent under this Agreement, and the retiring Collateral
Agent shall thereupon be discharged from its duties and obligations under this
Agreement.  After any retiring Collateral Agent's resignation, the provisions
of this Agreement shall inure to its benefit as to any actions taken or omitted
to be taken by it under this Agreement while it was Collateral Agent.

         Collateral Agent May Perform; Collateral Agent Appointed
Attorney-in-Fact.  If Pledgors shall fail to do any act or thing that they have
covenanted to do hereunder or if any warranty on the part of Pledgors contained
herein shall be breached, Collateral Agent or any Secured Party may (but shall
not be obligated to), subject to Section 30 of this Agreement, do the same or
cause it to be done or remedy any such breach, and may expend funds for such
purpose.  Any and all reasonable amounts so expended by Collateral Agent or
such Secured Party shall be paid by Pledgors promptly upon demand therefor,
with interest at the highest rate then in effect under the Credit Agreement
during the period from and including the date on which such funds were so
expended to the date of repayment.  Pledgors' obligations under this Section 15
shall survive the termination of this Agreement and the discharge of Pledgors'
other obligations under this Agreement, the Credit Agreement and the other
Credit Documents.  Pledgors hereby appoint Collateral Agent their
attorney-in-fact, with full authority in the place and stead of Pledgors and in
the name of Pledgors, or otherwise, from time to time in Collateral Agent's
discretion to take any action and to execute any instrument consistent with the
terms of this Agreement and the other Credit Documents which Collateral Agent
may deem necessary or advisable to

accomplish the purposes of this Agreement, except that with respect to any FCC
applications or filings or other actions subject to FCC rules, regulations or
policy, Collateral Agent shall serve as attorney-in-fact only to the extent
permitted under the Communications Act and FCC rules, regulations and policies.
The foregoing grant of authority is a power of attorney coupled with an
interest and such appointment shall be irrevocable for the term of this
Agreement.  Pledgors hereby ratify all that such attorney shall lawfully do or
cause to be done by virtue hereof.

         Indemnity.

         Indemnity.  Pledgors agree to indemnify, pay and hold harmless
    Collateral Agent and each of the Secured Parties and the officers,
    directors, employees, agents and Affiliates of Collateral Agent and each of
    the Secured Parties (collectively, the "Indemnitees") from and against any
    and all other liabilities, obligations, losses, damages, penalties,
    actions, judgments, suits, claims, costs (including, without limitation,
    settlement costs), expenses or disbursements of any kind or nature
    whatsoever (including, without limitation, the fees and disbursements of
    counsel for such Indemnitees in connection with any investigative,
    administrative or judicial proceeding commenced or threatened, whether or
    not such Indemnitee shall be designated a party thereto), which may be
    imposed on, incurred by, or asserted against that Indemnitee, in any manner
    relating to or arising out of this Agreement or any other Credit Document
    (including, without limitation, any misrepresentation by Pledgors in this
    Agreement or any other Credit Document) (the "indemnified liabilities");
    provided that Pledgors shall have no obligation to an Indemnitee hereunder
    with respect to indemnified liabilities if it has been determined by a
    final decision (after all appeals and the expiration of time to appeal) of
    a court of competent jurisdiction that such indemnified liability arose
    from the gross negligence or willful misconduct of that Indemnitee.  To the
    extent that the undertaking to indemnify, pay and hold harmless set forth
    in the preceding sentence may be unenforceable because it is violative of
    any law or public policy, Pledgors shall contribute the maximum portion
    which it is permitted to pay and satisfy under applicable law, to the
    payment and

    satisfaction of all indemnified liabilities incurred by the Indemnitees or
    any of them.

         Survival.  The obligations of Pledgors contained in this Section 16
    shall survive the termination of this Agreement and the discharge of
    Pledgors' other obligations under this Agreement and under the other Credit
    Documents.

         Reimbursement.  Any amounts paid by any Indemnitee as to which such
    Indemnitee has the right to reimbursement shall constitute Secured
    Obligations secured by the Pledged Collateral.

         Modification in Writing.  No amendment, modification, supplement,
termination or waiver of or to any provision of this Agreement, nor consent to
any departure by Pledgors therefrom, shall be effective unless the same shall
be made in accordance with the terms of the Credit Agreement and unless in
writing and signed by Collateral Agent and Pledgors.  Any amendment,
modification or supplement of or to any provision of this Agreement, any waiver
of any provision of this Agreement and any consent to any departure by Pledgors
from the terms of any provision of this Agreement shall be effective only in
the specific instance and for the specific purpose for which made or given.
Except where notice is specifically required by this Agreement or any other
Credit Document, no notice to or demand on Pledgors in any case shall entitle
Pledgors to any other or further notice or demand in similar or other
circumstances.

         Termination; Release.  When all the Secured Obligations have been paid
in full and the Commitments of the Banks to make any Loan shall have expired or
been sooner terminated, this Agreement shall terminate.  Upon termination of
this Agreement or any release of Pledged Collateral in accordance with the
provisions of the Credit Agreement, Collateral Agent shall, upon the request
and at the sole cost and expense of Pledgors, forthwith assign, transfer and
deliver to Pledgors, against receipt and without recourse to or warranty by
Collateral Agent, such of the Pledged Collateral to be released (in the case of
a release) as may be in possession of Collateral Agent and as shall not have
been sold or otherwise applied pursuant to the terms hereof, and, with

         Obligations Absolute.  All obligations of Pledgors hereunder shall be
absolute and unconditional irrespective of:

         any bankruptcy, insolvency, reorganization, arrangement, readjustment,

         Collateral Agent's Right to Sever Indebtedness.  (a)  Pledgors
acknowledge that (i) the Pledged Collateral does not constitute the sole source
of security for the payment and performance of the Secured Obligations and that
the Secured Obligations are also secured by other types of property of Pledgors
and their Affiliates in other jurisdictions (all such property, collectively,
the "Collateral"), (ii) the number of such jurisdictions and the nature of the
transaction of which this instrument is a part are such that it would have been
impracticable for the parties to allocate to each item of Collateral a specific
loan amount and to execute in respect of such item a separate credit agreement,
and (iii) Pledgors intend that Collateral Agent have the same rights with
respect to the Pledged Collateral, in any judicial proceeding relating to the
exercise of any right or remedy hereunder or otherwise, that Collateral Agent
would have had if each item of Collateral had been pledged or encumbered
pursuant to a separate credit agreement and security instrument.  In
furtherance of such intent, Pledgors agree to the greatest extent permitted by
law that Collateral Agent may at any time by notice (an "Allocation Notice") to
Pledgors allocate a portion of the Secured Obligations (the "Allocated
Indebtedness") to all or a specified portion of the Pledged Collateral and
sever from the remaining Secured Obligations the Allocated Indebtedness.  From
and after the giving of an Allocation Notice with respect to any of the Pledged
Collateral, the Secured Obligations hereunder shall be limited to the extent
set forth in the Allocation Notice and (as so limited) shall, for all purposes,
be construed as a separate credit obligation of Pledgors unrelated to the other
transactions contemplated by the Credit Agreement, any other Credit Document or
any document related to any thereof.  To the extent that the proceeds of any
judicial proceeding relating to the exercise of any right or remedy hereunder
of the Pledged Collateral shall exceed the Allocated Indebtedness, such
proceeds shall belong to Pledgors and shall not be available hereunder to
satisfy any Secured Obligations of Pledgors other than the Allocated
Indebtedness.  In any action or proceeding to exercise any right or remedy
under this Agreement which is commenced after the giving by Collateral Agent of
an Allocation Notice, the Allocation Notice shall be conclusive proof of the
limits of the Secured Obligations hereby secured, and Pledgors may introduce,
by way of defense or counterclaim, evidence thereof in any such action or
proceeding.  Notwithstanding any provision of this Section 28, the proceeds
received by Collateral Agent pursuant to this

Agreement shall be applied by Collateral Agent in accordance with the
provisions of Section 11 hereof.

         (b) Pledgors hereby waive to the greatest extent permitted under law
the right to a discharge of any of the Secured Obligations under any statute or
rule of law now or hereafter in effect which provides that the exercise of any
particular right or remedy as provided for herein (by judicial proceedings or
otherwise) constitutes the exclusive means for satisfaction of the Secured
Obligations or which makes unavailable any further judgment or any other right
or remedy provided for herein because Collateral Agent elected to proceed with
the exercise of such initial right or remedy or because of any failure by
Collateral Agent to comply with laws that prescribe conditions to the
entitlement to such subsequent judgment or the availability of such subsequent
right or remedy.  In the event that, notwithstanding the foregoing waiver, any
court shall for any reason hold that such subsequent judgment or action is not
available to Collateral Agent, Pledgors shall not (i) introduce in any other
jurisdiction any judgment so holding as a defense to enforcement against
Pledgors of any remedy in the Credit Agreement or any other Credit Document or
(ii) seek to have such judgment recognized or entered in any other
jurisdiction, and any such judgment shall in all events be limited in
application only to the state or jurisdiction where rendered and only with
respect to the collateral referred to in such judgment.

         (c) In the event any instrument in addition to the Allocation Notice
is necessary to effectuate the provisions of this Section 28, including,
without limitation, any amendment to this Agreement, any substitute promissory
note or affidavit or certificate of any kind, Collateral Agent may execute and
deliver such instrument as the attorney-in-fact of Pledgors.  Such power of
attorney is coupled with an interest and is irrevocable.

         (d) Notwithstanding anything set forth herein to the contrary, the
provisions of this Section 28 shall be effective only to the maximum extent
permitted by law.

         Future Advances.  This Agreement shall secure the payment of any
amounts advanced from time to time pursuant to the Credit Agreement.

         Facilitating Governmental Approvals; Specific Performance.  (a)  In
connection with the exercise by Collateral Agent of its rights under this
Agreement relating to the disposition of or operation of the Pledged Collateral
under any licenses issued by the FCC or any other authorizations, agreements,
permits, licenses, and franchises of any Pledgor, it may be necessary to obtain
the prior consent or approval of the FCC or other governmental authority to the
exercise of rights with respect to the Pledged Collateral.  To the extent that
any such consent or approval is required for any action that Collateral Agent
may take under this Agreement with respect to the Pledged Collateral, receipt
of such FCC or governmental authority approval shall be a condition precedent
to Collateral Agent's exercise of such rights.  In furtherance of the first
sentence of this Section, each Pledgor hereby agrees, at its own cost, to use
its best efforts to take any and all actions which Collateral Agent may request
in order to obtain such consents or approvals or any other governmental
authorization as may be necessary to enable Collateral Agent to exercise and
enjoy the full rights and benefits granted to it under this Agreement, the
Credit Agreement, or any other Credit Document, including, without limitation,
the preparation, execution, delivery or filing on any Pledgor's behalf and in
any Pledgor's name, or in such other name as may be appropriate or required, or
causing to be prepared, executed, delivered or filed, all applications,
certificates, filings, instruments, information, reports and other documents
(including, without limitation, any application for any assignment or transfer
of control of ownership).

         (b) Each Pledgor hereby acknowledges that a breach of any of its
obligations contained in this Agreement will cause irreparable injury to
Collateral Agent, and that such a breach would not be adequately compensable in
damages, and therefore each Pledgor agrees that its obligations under this
Agreement shall be specifically enforceable.

         Non-Disturbance.  To the extent required to obtain a security interest
under any Contract in the event of a

                             Registration Rights

         SECTION ..    Registration on Demand

         2.1.1  Demand.  At any time following six months from the date the
Warrants become exercisable, upon the written request (the "Demand") of the
Requisite Holders (the "Demand Holders") that the Company effect the
registration under the Securities Act of the number of Registrable Securities
specified by the Demand Holders, the Company shall, subject to the provisions
hereof, use its best efforts to effect, as soon as practicable and in any event
within 60 days after the Demand is received from the Demand Holders, the
registration under the Securities Act of the Registrable Securities which the
Company has been so requested to register by the Demand Holders.

         2.1.2  Shelf Registration.  At any time that the Company is eligible
to use a short-form registration statement for registering securities for sale
to the public at large, the Demand Holders may, at their  option, request (the
"Shelf Demand") that any registration statement effected pursuant to a Demand
be effected on a delayed or continuous basis, pursuant to Rule 415 under the
Securities Act (the "Shelf Registration").  The Company agrees to keep
effective such registration statement (the "Shelf Registration Statement")
until the  earlier of (i) such date as of which all the Registrable Securities
under the Shelf Registration Statement have been disposed of in the manner
described in such registration statement, and (ii) 180 days after the date on
which such Shelf Registration Statement is declared effective.

         2.1.3  Registration Statement Form.  Registrations under this Section
2.1 shall be on such appropriate registration form of the Commission as shall

Company.  The Company shall include in any such registration statement all
information which, in the opinion of counsel to the Company, is required to be
included.

         2.1.4  Effective Registration Statement.  A registration requested
pursuant to this Section 2.1 shall not be deemed to have been effected (i)
unless a registration statement with respect thereto has become effective, (ii)
if after it has become effective, such registration is interfered with by any
stop order, injunction or other order or requirement of the Commission or other
governmental agency or court for any reason not attributable to the Holders and
has not thereafter become effective, or (iii) if the conditions to closing
specified in the underwriting agreement, if any, entered into in connection
with such registration are not satisfied or waived, other than by reason of a
failure on the part of the Holders or (iv) if a Shelf Registration Statement,
if such registration statement has not been kept effective until the earlier of
(a) such date as of which all of the Registrable Securities under such Shelf

not available for registering securities for sale to the public at large) filed
by the Company with the Commission pertaining to an underwritten public
offering of convertible debt securities or equity securities for cash for the
account of the Company or another holder of securities of the Company, and in
such case the Holders are afforded the opportunity to include Registrable

Securities to be included in such registration shall have the right to request
that the Company not have a registration statement filed pursuant to a Demand
declared effective.  If the Demand Holders elect to pay or reimburse the
Company for the Company's out-of-pocket expenses incurred in connection with
such registration, such withdrawn registration statement shall not be counted
for purposes of the requests for registration to which such Demanding Holder is
entitled pursuant to Section 2.1.5 hereof.

         2.1.7  Selection of Underwriter.  If a registration under this Section
2.1 is an underwritten offering, the Holders of a majority of the Registrable
Securities to be included in such registration shall select a managing
underwriter or underwriters of recognized national standing reasonably
acceptable to the Company to administer the offering.

         2.1.8  Registration of Other Securities.  A registration statement
filed pursuant to the request of the Demand Holders may, subject to the
provisions of Section 2.5 hereof, include (i) Registrable Securities of Holders
not making a demand pursuant to this Section 2.1 and (ii) other securities of
the Company with respect to which registration rights have been granted and may
include securities of the Company being sold for the account of the Company.

         2.1.9  Suspension.  The Company may delay, suspend or withdraw the
registration of the Registrable Securities required pursuant to this Section
2.1 or the preparation or furnishing of a supplemental or amended prospectus
pursuant to Section 2.3(i) for a period not exceeding 90 days if the Company
shall in good faith determine that any such registration would require the
Company to include disclosure that would reasonably be expected to have a
detrimental effect on any proposal, negotiations or plan by the Company or any
of its subsidiaries to engage in any acquisition or disposition of assets or
any merger, consolidation, tender offer, reorganization or similar transaction,
or any other material corporate event contemplated by the Company.  In

quarterly report of the Company most recently filed with the Commission would
not be permitted, provided that this exception shall not permit delay or
suspension of registration beyond the filing of the next required annual or
quarterly filing under the Securities Exchange Act.

         SECTION ..  Incidental Registration.  If the Company, at any time or
any one or more occasions after the date of this Agreement, proposes to
register (other than pursuant to Section 2.1) any of its equity securities
under the Securities Act for sale to the public, whether for its own account or
for the account of other security holders or both (other than pursuant to
registrations on Form S-4 or Form S-8 or any successor form or other forms not
available for registering securities for sale to the public at large), the
Company shall give not less than 30 days' nor more than 90 days' prior written
notice to each Holder of Registrable Securities of its intention to do so.
Upon the written request of any Holder of Registrable Securities given within
20 days after receipt of such notice from the Company, the Company will use its
best efforts to cause the Registrable Securities requested to be registered to
be so registered under the Securities Act.  A request pursuant to this Section
2.2 shall state the number of Registrable Securities requested to be registered
and the intended method of distribution thereof.  In connection with any
registration subject to this Section 2.2, the Holders shall enter into such
underwriting, lock-up and other agreements, and shall execute and complete such
questionnaires and other documents, as are customary in a secondary offering.
The Company shall have the right to terminate or withdraw any registration
initiated by it under this Section 2.2 prior to the effectiveness of such
registration whether or not any Holder has elected to include any securities in
such registration.  Notwithstanding any other provision of this Agreement, if
the representative of the underwriters advises the Company in writing that
marketing factors require a limitation on the number of shares to be
underwritten, the number of shares to be included in the underwriting or
registration shall be allocated as set forth in Section 2.5 hereof.

         No registration effected under this Section 2.2 shall relieve the
Company of its obligation to effect the registration required under Section
2.1.

    used its best efforts to keep a registration statement effective during a
    period if it voluntarily takes any action that results in participating
    Holders not being able to sell such Registrable Securities during such
    period, unless such action (i) is required under applicable law or (ii) is
    determined in good faith by the Board of Directors of the Company to be in

    Securities for sale in any jurisdiction, and, if any such order is issued,

    documents as such seller, broker or underwriter may reasonably request in
    order to facilitate the public sale or other disposition of the Registrable
    Securities owned by such seller;

    Registration Statement under such securities or blue sky laws of such
    jurisdictions as each seller shall reasonably request, and do any and all
    other reasonable acts and things which may be necessary under such

    such seller or underwriter and shall be promptly returned to the Company or
    destroyed) so that, as thereafter delivered to the purchasers of such
    Registrable Securities, such Prospectus shall not include an untrue

         If any such Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder
shall have the right to require (i) the insertion therein of language, in form
and substance satisfactory to such Holder, to the effect that the holding by
such Holder of such securities is not to be construed as a recommendation by
such Holder of the investment quality of the Company's securities covered
thereby and that such holding does not imply that such Holder will assist in
meeting any future financial requirements of the Company, or (ii) in the event
that such reference to such Holder by name or otherwise is not in the judgment
of the Company, as advised by counsel, required by the Securities Act or any
similar federal statute or any state "blue sky" or securities law then in
force, the deletion of the reference to such Holder.

         SECTION ..  Expenses.  All expenses incurred in effecting the
registrations (whether or not such registrations are consummated) provided for
in this Article II, including without limitation all registration and filing
fees, printing expenses, fees and disbursements of counsel for the Company,
expenses of any audits incident to or required by any such registration
(including the costs of any comfort letter) and  expenses of complying with the

hereof, the costs and expenses associated with the filing required to be made

regulations of the NASD, provided such fees and expenses are not paid by the
underwriter), transfer taxes, fees of transfer agents and registrars, costs of
insurance (but excluding underwriting discounts and commissions to the extent
they relate to Registrable Securities), duplicating fees, delivery expenses,
expenses incurred with the listing of the securities on any securities
exchange, shall be paid by the Company, and the Company shall pay all
reasonable fees and disbursements of one counsel for the Holders of Registrable
Securities for the performance of the normal and customary functions of counsel
for selling shareholders in each such registration.

         SECTION ..  Marketing Restrictions.  If (i) any Holder of Registrable
Securities requests registration of Registrable Securities under Section 2.1 or
2.2, (ii) the offering proposed to be made is to be an underwritten public

written opinion that the total amount of securities to be included in such
offering would exceed the maximum amount of securities (the "Maximum Amount")
(as specified in such opinion) which can be marketed at a price reasonably
related to the then current market value of such securities and without
materially and adversely affecting such offering, then the rights of the
Company, the Holders of Registrable Securities and the holders of other
securities having the right to include such securities in such registration to
participate in such offering shall be as follows:

         If such registration shall have been proposed by the Company, (i) the
    Company shall be entitled to participate in such registration first; (ii)
    then Holders of Registrable Securities under this Agreement shall be
    entitled to participate in such registration (pro rata based on the number
    of Registrable Securities or shares of Common Stock, respectively, held by
    each) and (iii) other security holders of the Company shall be entitled to
    participate in such registration (pro rata based on the number of
    securities held by each security holder and in accordance with the relative
    priorities, if any, as shall exist among them).  If such registration shall
    have been requested by the Demand Holders of Registrable Securities
    pursuant to  Section 2.1 hereof, (i) the Holders of Registrable Securities
    shall be entitled to participate in such registration (pro rata based on
    the number of Registrable Securities held by each) first; and (ii) then the
    Company and other security holders of the Company entitled to participate
    will be entitled to participate in such registration (with the holders of
    such securities being entitled to participate in accordance with the
    relative priorities, if any, as shall exist among them), in each case with
    further pro rata allocations to the extent any such person has requested
    registration of fewer securities than such person is entitled to have
    registered so that the number of securities to be included in such
    registration will not exceed the Maximum Amount.  If such registration
    shall have been requested by the holders of other securities pursuant to a
    right granted by the Company to request such registration, (i) the holders
    requesting such registration shall be entitled to participate in such
    registration (with such holders being entitled to participate in accordance
    with the relative

    priorities, if any, as shall exist among them); (ii) then the Holders of
    Registrable Securities shall be entitled to participate in accordance with
    the number of shares held by them (pro rata based on the number of
    Registrable Securities or shares of Common Stock, respectively, held by
    each); and (iii) then the Company and other security holders of the Company
    entitled to participate will be entitled to participate in such
    registration (with the holders of such securities being entitled to
    participate in accordance with the relative priorities, if any, as shall
    exist among them), in each case with further pro rata allocations to the
    extent any such person has requested registration of fewer securities than
    such person is entitled to have registered so that the number of securities
    to be included in such registration will not exceed the Maximum Amount;

and no securities (issued or unissued) other than those registered and included
in the underwritten offering shall be offered for sale or other disposition in
a transaction which would require registration under the Securities Act (but
excluding any issuance of shares pursuant to registrations on Form S-4 or Form
S-8 or any successor form or other forms not available for registering capital
stock for sale to the public at large) until the expiration of 90 days after
the effective date of the Registration Statement in which Registrable
Securities were included pursuant to Section 2.2 or such shorter period as may
be acceptable to the Company and the Holders of a  majority of the Registrable
Securities who may be participating in such offering.

         SECTION ..  Termination of Rights.  Notwithstanding the foregoing
provisions of this Article II, the rights to registration shall terminate as to
any particular Registrable Securities when (a) a Registration Statement
covering such Registrable Securities has been declared effective and such
Registrable Securities have been disposed of in accordance with such effective
Registration Statement, (b) written opinion(s), to the effect that such
Registrable Securities may be sold without registration under the Securities
Act or applicable state law and without restriction as to the volume and timing
of such sale, shall have been received from counsel for the Company reasonably
acceptable to the Holders of a majority of such Registrable Securities, (c) the
Warrants expire unexercised or are otherwise terminated or (d) such Registrable

be filed by it under the Securities Act and the Securities Exchange Act and the
rules and regulations promulgated thereunder (or, if the Company is not
required to file such reports, it will, upon the written request of any Holder
of Registrable Securities as soon as practicable, make publicly available other
information so long as such information is necessary to permit sales under Rule
144), and will take such further actions as any Holder of Registrable
Securities may reasonably request, all to the extent required from time to time
to enable such Holder to sell Registrable Securities without registration under
the Securities Act within the limitation of the exemption provided by Rule 144.
Upon the request of any Holder of Registrable Securities, the Company shall
deliver to such Holder a written statement as to whether it has complied with
such requirements.

         SECTION ..  Indemnification.  ()     In the event of any registration
of any Registrable Securities under the Securities Act pursuant to this
Agreement, the Company will, and hereby does, indemnify and hold harmless, to
the fullest extent permitted by law, the seller of any Registrable Securities
covered by such Registration Statement, its directors and officers or general
and limited partners (and the directors and officers thereof) (each, a
"Person"), each person who participates as an underwriter or qualified
independent underwriter/pricer  ("independent underwriter"), if any, in the
offering or sale of such securities, each officer, director or partner of such
underwriter or independent underwriter, and each other Person, if any, who
controls such seller or any such underwriter within the meaning of the
Securities Act, against any and all losses, claims, damages or liabilities,
joint or several, and expenses (including fees of counsel and any amounts paid
in any settlement approved by the Company (which such approval shall not be
unreasonably withheld or delayed)) to which such seller, any such director or
officer or general or limited partner or any such underwriter or independent
underwriter, such officer, director or partner of such underwriter or
independent underwriter or controlling person may become subject under the
Securities Act, common law or

actions or proceedings, whether commenced or threatened, in respect thereof),
or expenses arise out of or are based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement
under which such securities were registered under the Securities Act or the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, (ii)
any untrue statement or alleged untrue statement of a material fact contained
in any preliminary, final or summary Prospectus (together with the documents
incorporated by reference or filed with the Commission) and any amendment
thereof or supplement thereto, or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading or (iii) any violation by the Company of any federal
or state rule or regulation applicable to the Company and relating to action
required of or inaction by the Company in connection with any such
registration, and the Company will reimburse as incurred such seller and each
such director, officer, general or limited partner, underwriter, independent
underwriter, director, or officer or partner of such underwriter or independent
underwriter and controlling person for any legal or any other expenses incurred
by any of them in connection with investigating or defending any such loss,
claim, liability, action or proceeding; provided, that the Company shall not be
liable to any such seller or any such director, officer, general or limited
partner, underwriter, independent underwriter, director or officer or partner
of such underwriter or independent underwriter or controlling person in any
such case to the extent that any such loss, claim, damage, liability (or action
or proceeding, whether commenced or threatened, in  respect thereof) or expense
arises out of or is based upon (i) any untrue statement or alleged untrue
statement or omission or alleged omission made in such Registration Statement
or amendment thereof or supplement thereto or in any such preliminary, final or
summary Prospectus in reliance upon and in conformity with information
furnished to the Company in writing by or on behalf of any such seller or any
such director, officer, general or limited partner, underwriter, independent

applicable to him to deliver a copy of a Prospectus or any supplements or
amendments thereto after the Company has made such documents available to such
Persons.  Such indemnity and reimbursement of expenses shall remain in full
force and effect following the transfer of such securities by such seller.

         ()    The Company, as a condition to including any Registrable
Securities in any Registration Statement filed in accordance with this
Agreement, shall have received an undertaking reasonably satisfactory to it
from the prospective seller of such Registrable Securities and any underwriter
or independent underwriter, to indemnify and hold harmless (in the same manner
and to the same extent as set forth in paragraph (a) of this Section 2.8) the
Company and its directors and officers and all other prospective sellers and
their directors, officers, general and limited partners and respective
controlling Persons (within the meaning of the Securities Act) with respect to
any statement or alleged statement in or omission or alleged omission from such
Registration Statement, any preliminary, final or summary Prospectus contained
therein, or any amendment or supplement thereto, if such statement or alleged
statement or omission or information has been furnished in writing to the
Company or its representative by or on behalf of such seller or underwriter
expressly for use in the preparation of such Registration Statement,
preliminary, final or summary Prospectus or amendment or supplement; provided,
however, that the aggregate amount which any such seller or prospective seller
shall be required to pay pursuant to such undertaking shall be limited to the
amount of the net proceeds received by such Person upon the sale of the
Registrable Securities pursuant to the Registration Statement giving rise to
such claim.  Such indemnity shall remain in full force and effect following the
transfer of such securities by such seller.

         ()    As soon as possible after receipt by an indemnified party
hereunder of written notice of the commencement of any action or proceeding
with respect to which a claim for indemnification may be made pursuant to this
Section 2.8, such indemnified party will, if a claim in respect thereof is to
be made against an indemnifying party, give written notice to the latter of the
commencement of such action; provided, that the failure of any indemnified
party to

obligations under the preceding paragraphs of this Section 2.8, except to the
extent that the indemnifying party is actually prejudiced by such failure to
give notice.  If any such claim or action shall be brought against an
indemnified party, and it shall notify the indemnifying party thereof, the
indemnifying party shall be entitled to participate therein, and, to the extent
that it wishes, jointly with any other similarly notified indemnifying party,
to assume the defense thereof with counsel reasonably satisfactory to the
indemnified party; provided, that the indemnifying party shall not be entitled
to so participate or so assume the defense if, in the indemnified party's
reasonable judgment, a conflict of interest between the indemnified party and
the indemnifying party exists or may exist in respect of such claim.  After
notice from the indemnifying party to such indemnified party of its election to
assume the defense of such claim or action, the indemnifying party shall not be
liable to the indemnified party under this Section 2.8 for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof unless the indemnifying party has failed to assume the defense
of such claim or to employ counsel reasonably satisfactory to such indemnified
party; provided that the indemnified parties shall have the right to employ one
counsel (in each case together with appropriate local counsel) (such counsel to
be selected by the Holders of a majority of the Registrable Securities included
in such registration) to represent such indemnified parties if, in such
indemnified parties' reasonable judgment, a conflict of interest between the
indemnified parties and the indemnifying parties exists or may exist in respect
of such claim, and in that event the fees and expenses of such separate counsel
shall be paid as incurred by the indemnifying party; and provided, further that
if, in the reasonable judgment of any of the indemnified parties, a conflict of
interest between such indemnified parties, and any other indemnified parties
exists in respect of such claim, such indemnified parties shall be entitled to
additional counsel or counsels and the indemnifying party shall be obligated to
pay the fees and expenses of such additional counsel or counsels.   No
indemnifying party will consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving
by the claimants or plaintiffs to such indemnified party of an unconditional
release from all liability in respect to such claim or litigation.  No
indemnifying party will be liable

for any settlement effected without its prior written consent, which consent
will not be unreasonably withheld or delayed.

         ()    Indemnification similar to that specified in the preceding
paragraphs of this Section 2.8 (with appropriate modifications) shall be given
by the Company and each seller of Registrable Securities with respect to any
required registration or other qualification of securities under any state
securities and "blue sky" laws.

         ()    If the indemnification provided for in this Section 2.8 is
unavailable or insufficient to hold harmless an indemnified party under Section
2.8(a) or (b) of this Agreement, then each indemnifying party shall contribute
to the amount paid or payable by such indemnified party as a result of the
losses, claims, damages or liabilities referred to in Section 2.8(a) or (b) in
such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and the indemnified party on the other hand
in connection with statements or omissions which resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations.  The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or other omission or alleged omission to state a material fact relates to
information supplied by the indemnifying party or the indemnified party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statements or omission.  The parties hereto
agree that it would not be just and equitable if contributions pursuant to this
Section 2.8(e) were to be determined by pro rata allocation or by any other
method of allocation which does not take account of the equitable
considerations referred to in the first sentence of this Section 2.8(e).  The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities referred to in the first sentence of this Section 2.8(e) shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any action or
claim (which shall be limited as provided in Section 2.8(c) if the indemnifying
party has assumed the defense of any such action in  accordance with the
provisions thereof) which is the subject of this Section 2.8(e).  No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any

person who was not guilty of such fraudulent misrepresentation.  Promptly after
receipt by an indemnified party under this Section 2.8(e) of notice of the
commencement of any action against such party in respect of which a claim for
contribution may be made against an indemnifying party under this Section
2.8(e), such indemnified party shall notify the indemnifying party in writing
of the commencement thereof if the notice specified in Section 2.8(c) has not
been given with respect to such action; provided that the omission so to notify
the indemnifying party shall not relieve the indemnifying party from any
liability which it may have to any indemnified party otherwise under this
Section 2.8(e), except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice.  Notwithstanding anything in this
Section 2.8(e) to the contrary, no indemnifying party (other than the Company)
shall be required pursuant to this Section 2.8(e) to contribute any amount in
excess of the proceeds received by such indemnifying party from the sale of
Registrable Securities in the offering to which the losses, claims, damages or
liabilities of the indemnified parties relate.

         ()    The provisions of this Section 2.8 shall be in addition to any
other rights to indemnification or contribution which any indemnified party may
have pursuant to law or contract and shall remain in full force and effect
following the transfer of the Registrable Securities by any such party.

                           Changes in Common Stock

         If, and as often as, there is any change in the Common Stock by way of
a combination or reclassification, or through a merger, consolidation,
reorganization or recapitalization, or by any other means, appropriate
adjustment shall be made in the provisions hereof so that the rights and
privileges granted hereby shall continue with respect to the Registrable
Securities as so changed.

                          SECURITIES PLEDGE AGREEMENT

         This SECURITIES PLEDGE AGREEMENT (the "Agreement"), dated as of
February 26, 1997, made by AMERICAN TELECASTING, INC., a Delaware corporation
having an office at 5575 Tech Center Drive, Suite 300, Colorado Springs, CO
80919 (the "Pledgor"), in favor of BANQUE INDOSUEZ, NEW YORK BRANCH, having an

(as hereinafter defined).

                               R E C I T A L S :

         A.  Pursuant to a certain credit agreement, dated as of the date

as Agent for the Banks, the Banks have agreed to make to or for the account of

         all dividends, cash, options, warrants, rights, instruments,
    distributions, returns of capital, income, profits and other property,
    interests or proceeds from time to time received, receivable or otherwise
    distributed to the Pledgor in respect of or in exchange for any or all of

    effect in any relevant jurisdiction (the "UCC") or under other relevant
    law) of any of the foregoing, and in any event, including, without
    limitation, any and all (i) proceeds of any insurance (except  payments

         Secured Obligations.  This Agreement secures, and the Pledged
Collateral is collateral security for, the payment and performance in full when
due, whether at stated maturity, by acceleration or otherwise (including,
without limitation, the payment of interest and other amounts which would
accrue and become due but for the filing of a petition in bankruptcy or the
operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11
U.S.C. Section 362(a)) of (i) all Obligations of the Pledgor now existing or
hereafter arising under or in respect of the Credit Agreement (including,
without limitation, the obligations of the Pledgor to pay principal, interest
and all other reasonable charges, fees, expenses, commissions,

indemnities and other payments related to or in respect of the obligations
contained in this Agreement (the obligations described in clauses (i) and (ii),
collectively, the "Secured Obligations").

         No Release.  Subject to Section 18 of this Agreement, nothing set
forth in this Agreement shall relieve the Pledgor from the performance of any
term, covenant, condition on the Pledgor's part to be performed or observed
under or in respect of any of the Pledged Collateral or from any liability to
the Person under or in respect of any of the Pledged Collateral or shall impose
any obligation on Collateral Agent or any Secured Party to perform or observe
any such term, covenant, condition or agreement on the Pledgor's part to be so
performed or observed or shall impose any liability on Collateral Agent or any
Secured Party for any act or omission on the part of the Pledgor relating
thereto or for any breach of any representation or warranty on the part of the
Pledgor contained in this Agreement, or any other Credit Document or under or
in respect of the Pledged Collateral or made in connection herewith or
therewith.  Subject to Section 18 of this Agreement, the obligations of the
Pledgor contained in this Section 3 shall survive the termination of this
Agreement and the discharge of the Pledgors' other obligations under this
Agreement and the other Credit Documents.

         Delivery of Pledged Collateral.

         All certificates, agreements or instruments representing or evidencing
the Pledged Collateral, to the extent not previously delivered to Collateral
Agent, shall immediately upon receipt thereof by the Pledgor be delivered to
and held by or on behalf of Collateral Agent pursuant hereto.  All Pledged
Collateral shall be in suitable form for transfer by delivery or shall be
accompanied by duly executed instruments of transfer or assignment in blank
(with signatures appropriately guaranteed), all in form and substance

satisfactory to Collateral Agent.  Subject to the provisions of Section 29 of
this Agreement, Collateral Agent shall have the right, at any time upon the
occurrence and during the continuance of an Event of Default, to endorse,
assign or otherwise transfer to or to register in the name of Collateral Agent
or any of its nominees any or all of the Pledged Collateral.  Collateral Agent
shall provide the Pledgor with notice of any endorsement, assignment or other
transfer made pursuant to the preceding sentence.  In addition, upon the
occurrence and during the continuance of an Event of Default, Collateral Agent
shall have the right at any time to exchange certificates representing or
evidencing Pledged Collateral for certificates of smaller or larger
denominations.

         If an issuer of Pledged Shares is incorporated in a jurisdiction which
does not permit the use of certificates to evidence equity ownership, then the
Pledgor shall, to the extent permitted by applicable law, record such pledge on
the stock register of such issuer, execute any customary stock pledge forms or
other documents necessary or appropriate to complete the pledge and give
Collateral Agent the right to  transfer the Pledged Shares under the terms
hereof and provide to Collateral Agent an opinion of counsel, in form and
substance satisfactory to Collateral Agent, confirming such pledge.

         Notwithstanding any provision of this Section 4 to the contrary, if
the exercise of any rights provided in this Section 4 or Section 10 relates to
the ownership or control of any radio, television or other license, permit,
certificate or approval granted or issued by the FCC or any other Governmental
Authority (including, without limitation, any multichannel or single channel
multipoint distribution service, local multipoint distribution service,
operational-fixed microwave service, cable television relay service station,
business radio, instructional television fixed service, earth station or
experimental licenses or permits issued by the FCC) (each, a "Governmental
License") held by the Pledgor or a subsidiary of the Pledgor and it may be
necessary to obtain the consent or approval of the FCC prior to the exercise of
such rights, the provisions of Section 29 of this Agreement shall apply.

         The Pledgor agrees that at any time and from time to time, at the sole
cost and expense of such Pledgor, the Pledgor shall promptly execute and
deliver all further instruments and documents, including, without limitation,
supplemental or additional UCC-1 financing statements, and take all further
action that may be necessary or that Collateral Agent may reasonably request,
in order to perfect and protect the pledge, security interest and Lien granted
or purported to be granted hereby or to enable Collateral Agent to exercise and
enforce its rights and remedies hereunder with respect to any Pledged
Collateral.

promptly (and in any event within three Business Days) deliver to Collateral
Agent a pledge amendment, duly executed by the Pledgor, in substantially the
form of Exhibit 1 hereto (the "Pledge Amendment"), in respect of the additional
Pledged Shares which are to be pledged pursuant to this Agreement, and
confirming the attachment of the Lien hereby created on and in respect of such
Pledged Collateral.  The Pledgor hereby authorizes Collateral Agent to attach
each Pledge Amendment to this Agreement and agrees that all Pledged Shares
listed on any Pledge Amendment delivered to Collateral  Agent shall for all
purposes hereunder be considered Pledged Collateral.

         Representations, Warranties and Covenants.  The Pledgor represents,
warrants and covenants as follows (as to itself only):

         No Liens.  The Pledgor is, and at the time of any delivery of any
    Pledged Collateral to Collateral Agent pursuant to Section 4 of this
    Agreement will be, the sole legal and beneficial owner of the Pledged
    Collateral pledged by it pursuant to this Agreement.  All Pledged
    Collateral is on the date hereof, and will be, so owned by the Pledgor, as
    applicable, free and clear of any Lien except for the Lien created by this
    Agreement.

         Authorization, Enforceability.  The Pledgor has the requisite
    corporate power, authority and legal right to pledge and grant a security
    interest in all of the Pledged Collateral pledged by it pursuant to this
    Agreement, and

    this Agreement constitutes the legal, valid and binding obligation of the
    Pledgor, enforceable against the Pledgor in accordance with its terms.

         No Consents, etc.  No consent of any party (including, without
    limitation, any stockholders or creditors of the Pledgor) and no consent,
    authorization, approval, or other action by, and no notice to or filing
    with, any Governmental Authority or regulatory body or other Person is
    required either (x) for the pledge by the Pledgor of the Pledged Collateral
    pledged by it pursuant to this Agreement or for the execution, delivery or
    performance of this Agreement by the Pledgor, or (y) for the exercise by
    Collateral Agent of the voting or other rights provided for in this
    Agreement, or (z) for the exercise by Collateral Agent of the remedies in
    respect of the Pledged Collateral pursuant to this Agreement; provided,
    however, that under the Communications Act and the rules and regulations of
    the FCC, FCC consent may be required prior to the transfer of control or
    assignment of any Governmental License issued by the FCC, or the exercise
    of any voting rights or management over the Pledgor or an issuer of Pledged
    Shares to the extent it holds, owns or controls any Governmental License
    issued by the FCC.

         Due Authorization and Issuance.  All of the Pledged Shares have been,
    and to the extent hereafter  issued will be upon such issuance, duly
    authorized and validly issued and fully paid and nonassessable.

         Chief Executive Office.  The Pledgor's chief executive office is
    located at 5575 Tech Center Drive, Suite 300, Colorado Springs, Colorado
    80919.  Pledgor shall not move its chief executive office except to such
    new location as Pledgor may establish in accordance with the last sentence
    of this Section 6(e).  Pledgor shall not establish a new location for its
    chief executive office nor shall it change its name until (i) it shall have
    given Collateral Agent not less than 45 days' prior written notice of its
    intention so to do, clearly describing such new location or name and
    providing such other information in connection therewith as Collateral
    Agent or any Secured Party may request, and (ii) with respect to such new

    location or name, Pledgor shall have taken all action satisfactory to
    Collateral Agent and the Secured Parties to maintain the perfection and
    priority of the security interest of Collateral Agent for the benefit of
    the Secured Parties in the Pledged Collateral intended to be granted
    hereby.

         Delivery of Pledged Collateral; Filings.  The Pledgor has delivered to
    Collateral Agent all certificates representing the Pledged Shares and
    Intercompany Notes and has caused to be filed with the Secretary of State
    of the State of New York, the State of incorporation of the Pledgor and the
    State of Colorado, which is the State of the chief executive office of the
    Pledgor, UCC-1 financing statements evidencing the Lien created by this
    Agreement, and such delivery, filing and pledge of the Pledged Collateral
    pursuant to this Agreement creates a valid and perfected first priority
    security interest in the Pledged Collateral securing the payment of the
    Secured Obligations pursuant to the UCC, including, without limitation, the
    UCC as in effect in the States of New York, the State of incorporation of
    the Pledgor and the State of Colorado, which is the State of the chief
    executive office of the Pledgor.

         Pledged Collateral.  All information set forth herein, including the
    Schedules annexed hereto, and all information contained in any documents,
    schedules and lists heretofore delivered to any Secured Party in connection
    with this Agreement, in each case, relating to the  Pledged Collateral is
    accurate and complete in all respects.

         No Violations, etc.  The pledge of the Pledged Collateral pursuant to
    this Agreement does not violate Regulation G, T, U or X of the Federal
    Reserve Board.

         Ownership of Pledged Collateral.  Except as otherwise permitted by the
    Credit Agreement, the Pledgor at all times will be the sole beneficial
    owner of the Pledged Collateral pledged by it pursuant to this Agreement.

         No Options, Warrants, etc.  Except as disclosed in the Credit
    Agreement, there are no options, warrants, calls, rights, commitments or
    agreements of any character to which the Pledgor is a party or by which it
    is bound obligating the Pledgor to issue, deliver or sell or cause to be
    issued, delivered or sold, additional securities of any issuer of the
    Pledged Shares or obligating any issuer of the Pledged Shares to grant,
    extend or enter into any such option, warrant, call, right, commitment or
    agreement.  There are no voting trusts or other agreements or
    understandings to which the Pledgor or any issuer of the Pledged Shares is
    a party with respect to the voting of the securities of any issuer of the
    Pledged Shares.

         Endorsement, Assignment or Pledge of Instruments.  None of the Pledged
    Collateral is, as of the date of this Agreement, and as to Pledged
    Collateral which arises from time to time after such date will be,
    evidenced by any instrument, note or chattel paper, except such as have
    been or will be endorsed, assigned or pledged and delivered to Collateral
    Agent by Pledgors simultaneously with the creation thereof.

         Systems.  The Pledged Shares include the Pledgor's interest in each
    Credit Party operating Systems or holding System Agreements.

         Voting Rights; Distributions; etc.

         So long as no Event of Default shall have occurred and be continuing:

         (i)  The Pledgor shall be entitled to exercise any and all voting and
              other consensual rights pertaining to  the Pledged Shares pledged
              by it pursuant to this Agreement or any part thereof for any
              purpose not inconsistent with the terms or purpose of this
              Agreement or any of the other Credit Documents and each Pledgor
              shall not in any event exercise such rights in any manner which
              may have an adverse effect on the value of its respective Pledged
              Collateral or the

               security intended to be provided by this Agreement.

         (ii)  Subject to the terms of the Credit Agreement, each Pledgor shall
               be entitled to receive and retain, and to utilize free and clear
               of the Lien of this Agreement, any and all Distributions, but
               only if and to the extent made in accordance with the provisions
               of the Credit Agreement; provided, however, that any and all
               such Distributions consisting of rights or interests in the form
               of securities shall be, and shall be forthwith delivered to
               Collateral Agent to hold as Pledged Collateral and shall, if
               received by the Pledgor, be received in trust for the benefit of
               Collateral Agent, be segregated from the other property or funds
               of such Pledgor, and be forthwith delivered to Collateral Agent
               as Pledged Collateral in the same form as so received (with any
               necessary endorsement).

         (iii) Collateral Agent shall be deemed without further action or
               formality to have granted to each Pledgor all necessary consents
               relating to voting rights and shall, if necessary, upon written
               request of the Pledgor and at such Pledgor's sole cost and
               expense, from time to time execute and deliver (or cause to be
               executed and delivered) to such Pledgor all such instruments as
               such Pledgor may reasonably request in order to permit such
               Pledgor to exercise the voting and other rights which it is
               entitled to exercise pursuant to Section 7(a)(i) hereof and to
               receive the Distributions which it is authorized to receive and
               retain pursuant to Section 7(a)(ii) hereof.

         (b) Upon the occurrence and during the continuance of an Event of
Default:

         (i) All rights of the Pledgor to exercise the voting and other
             consensual rights it would otherwise be entitled to exercise
             pursuant to Section 7(a)(i) hereof without any action or the
             giving of any notice shall cease, and all such rights shall
             thereupon become vested in Collateral Agent, which shall thereupon
             have the sole right to  exercise such voting and other consensual
             rights; provided, however, to the extent the Pledgor or an issuer
             of Pledged Shares hold, own or control any Governmental License
             issued by the FCC, if and to the extent required under the
             Communications Act or the FCC's rules, until the FCC has consented
             to a transfer of control or assignment of Pledgor, an issuer of
             Pledged Shares, or such Governmental License issued by the FCC,
             Pledgor shall continue to exercise the voting and other consensual
             rights.

        (ii) All rights of the Pledgor to receive Distributions which it
             would otherwise be authorized to receive and retain pursuant to
             Section 7(a)(ii) hereof shall cease and all such rights shall
             thereupon become vested in Collateral Agent, which shall thereupon
             have the sole right to receive and hold as Pledged Collateral such
             Distributions.

       (iii) Subject to any necessary prior or subsequent FCC approval,
             Collateral Agent shall be entitled to the appointment, as a matter
             of right and without giving notice to the Pledgor, of a receiver
             with respect to the Pledged Collateral, without regard to the
             adequacy or inadequacy of any Pledged Collateral for the Secured
             Obligations or the solvency or insolvency of any person or entity
             then legally or equitably liable for the Secured Obligations or
             any portion thereof, and each Pledgor does hereby irrevocably
             consent to such appointment.  Any such receiver shall have all the
             usual qualifications, powers and duties of receivers in similar
             cases, including the full power to conduct the business of the
             Pledgors.

       (c) The Pledgor shall, at such Pledgor's sole cost and expense, from
time to time execute and deliver to Collateral Agent and any other Person
directed by Collateral

Agent, appropriate instruments as Collateral Agent may request in order to
permit Collateral Agent to exercise the voting and other rights which it may be
entitled to exercise pursuant to Section 7(b)(i) hereof and to receive all
Distributions which it may be entitled to receive under Section 7(b)(ii)
hereof.

         (d) All Distributions which are received by the Pledgor contrary to
the provisions of Section 7(b)(ii) hereof shall be received in trust for the
benefit of Collateral Agent, shall be segregated from other funds of such
Pledgor and shall immediately be paid over to Collateral Agent as Pledged
Collateral in the same form as so received (with any necessary endorsement).

         Transfers and Other Liens; Additional Shares; Principal Office.

         The Pledgor shall not (i) sell, convey, assign or otherwise dispose
of, or grant any option, right or warrant with respect to, any of the Pledged
Collateral pledged by it pursuant to this Agreement, (ii) create or permit to
exist any Lien upon or with respect to any Pledged Collateral pledged by it
pursuant to this Agreement other than the Lien granted to Collateral Agent
under this Agreement, or (iii) permit any issuer of the Pledged Shares to
merge, consolidate or change its legal form unless a majority of the
outstanding capital stock of the surviving or resulting corporation is, upon
such merger or consolidation, pledged to Collateral Agent pursuant to a pledge
agreement in form and substance, satisfactory to Collateral Agent, and no cash,
securities or other property is distributed in respect of the outstanding
shares of any other constituent corporation.

         The Pledgor shall (i) cause each issuer of the Pledged Shares not to
issue any stock or other securities in addition to or in substitution for the
Pledged Shares issued by such issuer, except to such Pledgor and (ii) pledge
hereunder, immediately upon its acquisition (directly or indirectly) thereof,
any and all additional shares of capital stock or other equity securities of
any issuer of the Pledged Shares which are required to be pledged hereunder.

         Reasonable Care.  Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Pledged Collateral in
its possession if such Pledged Collateral is accorded treatment substantially
equivalent to that which Collateral Agent, in its individual capacity, accords
its own property consisting of similar instruments or interests, it being
understood that neither the Collateral Agent nor any of the Secured Parties
shall have responsibility for (i) ascertaining or taking action with respect to
calls, conversions, exchanges, maturities, tenders or other matters relating to
any Pledged Collateral, whether or not Collateral Agent or any other Secured
Party has or is deemed to have knowledge of such matters, or (ii) taking any
necessary steps to preserve rights against any Person with respect to any
Pledged Collateral.

         Remedies Upon Default; Decisions Relating to Exercise of Remedies.

If any Event of Default shall have occurred and be continuing, subject to the
provisions of Section 29 of this Agreement, Collateral Agent shall have the
right, in addition to other rights and remedies provided for herein or
otherwise available to it to be exercised from time to time, (i) to retain and
apply the Distributions to the Secured Obligations as provided in Section 11
hereof, and (ii) to exercise all the rights and remedies of a secured party on
default under the UCC, and Collateral Agent may also in its sole discretion,
without notice except as specified below, sell the Pledged Collateral or any
part thereof (including, without limitation, any partial interest in the
Pledged Shares) in one or more parcels at public or private sale, at any
exchange, broker's board or at any of Collateral Agent's offices or elsewhere,
for cash, on credit or for future delivery, and at such price or prices and
upon such other terms as Collateral Agent may deem commercially reasonable,
irrespective of the impact of any such sales on the market price of the Pledged
Collateral.  Collateral Agent or any other Secured Party or any of their
respective Affiliates may be the purchaser of any or all of the Pledged
Collateral at any such sale and shall be entitled, for the purpose of bidding
and making settlement or payment of the purchase price for all or any portion
of the Pledged Collateral sold at such sale, to use and apply any of the
Secured Obligations owed to such Person as a credit on account of the purchase
price of any Pledged Collateral payable by such Person

at such sale.  Each purchaser at any such sale shall acquire the property sold
absolutely free from any claim or right on the part of the Pledgor, and Pledgor
hereby waives (to the fullest extent permitted by law) all rights of
redemption, stay and/or appraisal which it now has or may at any time in the
future have under any rule of law or statute now existing or hereafter enacted. 
The Pledgor acknowledges and agrees that, to the extent notice of sale shall be
required by law, five (5) days' notice to such Pledgor of the time and place of
any public sale or the time after which any private sale is to be made shall
constitute reasonable notification.  No notification need be given to the
Pledgor if it has signed, after the occurrence of an Event of Default, a
statement renouncing or modifying any right to notification of sale or other
intended disposition.  Collateral Agent shall not be obligated to make any sale
of Pledged Collateral regardless of notice of sale having been given.
Collateral Agent may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor,  and such sale may, without
further notice, be made at the time and place to which it was so adjourned. The
Pledgor hereby waives any claims against Collateral Agent arising by reason of
the fact that the price at which any Pledged Collateral may have been sold at
such a private sale was less than the price which might have been obtained at a
public sale, even if Collateral Agent accepts the first offer received and does
not offer such Pledged Collateral to more than one offeree. Notwithstanding any
provision of this subsection 10(a) to the contrary, in the event of a private
or public sale of the Pledged Collateral, prior to the consummation of the
sale, to the extent required under the Communications Act of 1934, as amended,
or any successor statute or law (the "Communications Act"), the prior consent
of the FCC pursuant to the Communications Act and the rules and regulations of
the FCC will be obtained.

         The Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended (the "Securities Act"), and
applicable state securities laws, Collateral Agent may be compelled, with
respect to any sale of all or any part of the Pledged Collateral, to limit
purchasers to Persons who will agree, among other things, to acquire the
Pledged Collateral for their own account, for investment and not with a view to
the distribution or resale thereof.  The Pledgor acknowledges that any such
private sales may be at prices and on terms less favorable to Collateral Agent
than those obtainable through a public sale without such

restrictions (including, without limitation, a public offering made pursuant to
a registration statement under the Securities Act), and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner and that Collateral Agent shall have
no obligation to engage in public sales and no obligation to delay the sale of
any Pledged Collateral for the period of time necessary to permit the issuer
thereof to register it for a form of public sale requiring registration under
the Securities Act or under applicable state securities laws, even if such
issuer would agree to do so.

         Notwithstanding the foregoing and to the extent commercially
reasonable, each Pledgor shall, upon the occurrence and during the continuance
of an Event of Default, at the request of Collateral Agent, for the benefit of
Collateral Agent, cause any registration, qualification under or compliance
with any federal or state securities law or laws to be effected with respect to
all or any part of the Pledged  Collateral as soon as practicable and at such
Pledgor's sole cost and expense.  The Pledgor will use its best efforts to
cause such registration to be effected (and be kept effective) and will use its
best efforts to cause such qualification and compliance to be effected (and be
kept effective) as may be so requested and as would permit or facilitate the
sale and distribution of such Pledged Collateral, including, without
limitation, registration under the Securities Act (or any similar statute then
in effect), appropriate qualifications under applicable blue sky or other state
securities laws and appropriate compliance with any other government
requirements.  The Pledgor will cause Collateral Agent to be kept advised in
writing as to the progress of each such registration, qualification or
compliance and as to the completion thereof, will furnish to Collateral Agent
such number of prospectuses, offering circulars or other documents incident
thereto as Collateral Agent from time to time may request, and will indemnify
and will cause the issuer of the Pledged Collateral to indemnify Collateral
Agent and all others participating in the distribution of such Pledged
Collateral against all claims, losses, damages and liabilities caused by any
untrue statement (or alleged untrue statement) of a material fact contained
therein (or in any related registration statement, notification or the like) or
by any omission (or alleged omission) to state therein (or in any related
registration statement, notification or the like) a material fact required to
be stated therein or necessary to make the statements therein not misleading.

         If Collateral Agent determines to exercise its right to sell any or
all of the Pledged Collateral, upon written request, each Pledgor shall from
time to time furnish to Collateral Agent all such information as Collateral
Agent may request in order to determine the number of securities included in
the Pledged Collateral which may be sold by Collateral Agent as exempt
transactions under the Securities Act and the rules of the Securities and
Exchange Commission thereunder, as the same are from time to time in effect.

         The Pledgor recognizes that, by reason of certain prohibitions
contained in laws, rules, regulations or orders of any foreign Governmental
Authority, Collateral Agent may be compelled, with respect to any sale of all
or any part of the Pledged Collateral, to limit purchasers to those who meet
the requirements of such foreign Governmental Authority.  The Pledgor
acknowledges that any such sales may be at prices and on terms less favorable
to Collateral Agent than those obtainable through a public sale without such
restrictions,  and, notwithstanding such circumstances, agrees that any such
restricted sale shall be deemed to have been made in a commercially reasonable
manner and that Collateral Agent shall have no obligation to engage in public
sales.

         In addition to any of the other rights and remedies hereunder,
Collateral Agent shall have the right to institute a proceeding seeking
specific performance in connection with any of the agreements or obligations
hereunder.

         Without limiting the generality of the provisions in Section 15
hereof, Pledgor hereby constitutes and appoints Collateral Agent, with full
power of substitution, its true and lawful attorney-in-fact, in its name, place
and stead to take any action upon the occurrence and during the continuance of
an Event of Default required to reflect the foreclosure sale of the Pledged
Collateral or the exercise of any remedy hereunder.  The foregoing grant of
authority is a power of attorney coupled with an interest and such appointment
shall be irrevocable for the term of this Agreement.

         Application of Proceeds.  All Distributions held from time to time by
Collateral Agent and all cash proceeds received by Collateral Agent in respect
of any sale of, collection from,

or other realization upon all or any part of the Pledged Collateral pursuant to
the exercise by Collateral Agent of its remedies as a secured creditor as
provided in Section 10 hereof shall be applied, together with any other sums
then held by Collateral Agent pursuant to this Agreement, promptly by
Collateral Agent as follows:

         First, to the payment of all reasonable costs and expenses, fees,
    commissions and taxes of such sale, collection or other realization,
    including, without limitation, reasonable compensation to Collateral Agent
    and its agents and counsel, and all reasonable expenses, liabilities and
    advances made or incurred by Collateral Agent in connection therewith,
    together with interest on each such amount at the highest rate then in
    effect under the Credit Agreement from and after the date such amount is
    due, owing or unpaid until paid in full;

         Second, to the payment of all other reasonable costs and expenses of
    such sale, collection or other realization, including, without limitation,
    reasonable compensation to the Banks and their agents and counsel and all
    reasonable expenses, liabilities and advances made or  incurred by the
    Banks in connection therewith, together with interest on each such amount
    at the highest rate then in effect under the Credit Agreement from and
    after the date such amount is due, owing or unpaid until paid in full;

         Third, to the indefeasible payment in full in cash of interest and all
    amounts other than principal under the Credit Agreement at any time and
    from time to time owing by the Pledgor under or in connection with the
    Credit Agreement, ratably according to the unpaid amounts thereof, without
    preference or priority of any kind among amounts so due and payable,
    together with interest on each such amount at the highest rate then in
    effect under the Credit Agreement from and after the date such amount is
    due, owing or unpaid until paid in full;

         Fourth, to the indefeasible payment in full in cash of principal at
    any time and from time to time owing by the Pledgor under or in connection
    with the Credit

    Agreement, ratably according to the unpaid amounts thereof, without
    preference or priority of any kind, among amounts of principal so due and
    payable, together with interest on each such amount at the highest rate
    then in effect under the Credit Agreement from and after the date such
    amount is due, owing or unpaid until paid in full; and

         Fifth, to the applicable Pledgor, or its successors or assigns or to
    whomsoever may be lawfully entitled to receive the same or as a court of
    competent jurisdiction may direct, of any surplus then remaining from such
    proceeds.

         Expenses.  The Pledgor will upon demand pay to Collateral Agent the
amount of any and all expenses, including the reasonable fees and expenses of
its counsel and the fees and expenses of any experts and agents, which
Collateral Agent may incur in connection with (i) the collection of the Secured
Obligations, (ii) the enforcement and administration of this Agreement, (iii)
the custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Pledged Collateral, (iv) the exercise or
enforcement of any of the rights of Collateral Agent or any Secured Party
hereunder or (v) the failure by the Pledgor to perform or observe any of the
provisions hereof.  All amounts payable by the Pledgor under this Section 12
shall be due upon demand and shall be part of the Secured Obligations.  The
Pledgor's  obligations under this Section 12 shall survive the termination of
this Agreement and the discharge of such Pledgor's other obligations hereunder.

         No Waiver; Cumulative Remedies.

         No failure on the part of Collateral Agent to exercise, no course of
dealing with respect to, and no delay on the part of Collateral Agent 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 hereunder preclude any other or further exercise thereof or the exercise
of any other right, power or remedy.  The remedies herein provided are
cumulative and are not exclusive of any remedies provided by law.

         In the event Collateral Agent shall have instituted any proceeding to
enforce any right, power or remedy under this instrument by foreclosure, sale,
entry or otherwise, and such proceeding shall have been discontinued or
abandoned for any reason or shall have been determined adversely to Collateral
Agent, then and in every such case, each Pledgor, Collateral Agent and each
holder of any of the Secured Obligations shall be restored to their respective
former positions and rights hereunder with respect to the Pledged Collateral,
and all rights, remedies and powers of Collateral Agent and the Secured Parties
shall continue as if no such proceeding had been instituted.

         Collateral Agent.  Collateral Agent has been appointed as collateral
agent pursuant to the Credit Agreement.  The actions of Collateral Agent
hereunder are subject to the provisions of the Credit Agreement.  Collateral
Agent shall have the right hereunder to make demands, to give notices, to
exercise or refrain from exercising any rights, and to take or refrain from
taking action (including, without limitation, the release or substitution of
Pledged Collateral), in accordance with this Agreement and the Credit
Agreement.  Collateral Agent may resign and a successor Collateral Agent may be
appointed in the manner provided in the Credit Agreement; provided, however,
that at the time of appointment of a successor Collateral Agent, if Collateral
Agent, through its possession, control, or ownership of Pledged Collateral or
otherwise, holds, owns, or controls any Governmental License issued by the FCC
such that the FCC must consent to the appointment of a successor Collateral
Agent, until the FCC has consented to the appointment of a successor Collateral
Agent the Collateral  Agent shall retain control over such Pledged Collateral
or Government Licenses.  Upon the acceptance of any appointment as Collateral
Agent by a successor Collateral Agent, that successor Collateral Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Collateral Agent under this Agreement, and the
retiring Collateral Agent shall thereupon be discharged from its duties and
obligations under this Agreement.  After any retiring Collateral Agent's
resignation, the provisions of this Agreement shall inure to its benefit as to
any actions taken or omitted to be taken by it under this Agreement while it
was Collateral Agent.

         Collateral Agent May Perform; Collateral Agent Appointed
Attorney-in-Fact.  If the Pledgor shall fail to do any act or thing that it has
covenanted to do hereunder or any warranty on the part of such Pledgor
contained herein shall be breached, Collateral Agent or any Secured Party may
(but shall not be obligated to), subject to the provisions of Section 29 of
this Agreement, do the same or cause it to be done or remedy any such breach,
and may expend funds for such purpose.  Any and all amounts so expended by
Collateral Agent or such Secured Party shall be paid by such Pledgor promptly
upon demand therefor, with interest at the highest rate then in effect under
the Credit Agreement during the period from and including the date on which
such funds were so expended to the date of repayment.  The Pledgor's
obligations under this Section 15 shall survive the termination of this
Agreement and the discharge of such Pledgor's other obligations under this
Agreement, the Credit Agreement and any other Credit Document.  The Pledgor
hereby appoints Collateral Agent its attorney-in-fact with an interest, with
full authority in the place and stead of such Pledgor and in the name of such
Pledgor, or otherwise, from time to time in Collateral Agent's discretion to
take any action and to execute any instrument consistent with the terms of this
Agreement and the other Credit Documents which the Collateral Agent may deem
necessary or advisable to accomplish the purposes of this Agreement except that
with respect to any FCC applications or filings or other action subject to FCC
rules, regulations and policies, Collateral Agent shall serve as
attorney-in-fact only to the extent permitted under the Communications Act and
FCC rules, regulations and policies.  The foregoing grant of authority is a
power of attorney coupled with an interest and such appointment shall be
irrevocable for the term of this Agreement.  The Pledgor hereby ratifies all
that such attorney shall lawfully do or cause to be done by virtue hereof.

         Indemnity.

         Indemnity.  The Pledgor agrees to indemnify, pay and hold harmless
Collateral Agent and each of the Secured Parties and the officers, directors,
employees, agents and affiliates of Collateral Agent and each of the Secured
Parties (collectively called the "Indemnitees") from and against any and all
other liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, claims, costs (including, without limitation, settlement costs),
expenses or

___________________________________________


disbursements of any kind or nature whatsoever (including, without limitation,
the reasonable fees and disbursements of counsel for such Indemnitees in
connection with any investigative, administrative or judicial proceeding
commenced or threatened, whether or not such Indemnitee shall be designated a
party thereto), which may be imposed on, incurred by, or asserted against that
Indemnitee, in any manner relating to or arising out of this Agreement or any
other Credit Document (including, without limitation, any misrepresentation by
the Pledgor in this Agreement or any other Credit Document) (the "indemnified
liabilities"); provided that the Pledgors shall not have any obligation to an
Indemnitee hereunder with respect to indemnified liabilities if it has been
determined by a final decision (after all appeals and the expiration of time to
appeal) by a court of competent jurisdiction that such indemnified liability
arose from the gross negligence or willful misconduct of that Indemnitee.  To
the extent that the undertaking to indemnify, pay and hold harmless set forth
in the preceding sentence may be unenforceable because it is violative of any
law or public policy, each Pledgor shall contribute the maximum portion which
it is permitted to pay and satisfy under applicable law, to the payment and
satisfaction of all indemnified liabilities incurred by the Indemnitees or any
of them.

         Survival.  The obligations of each Pledgor contained in this Section
16 shall survive the termination of this Agreement and the discharge of each
Pledgor's other obligations under this Agreement and under the other Credit
Documents.

         Reimbursement.  Any amounts paid by any Indemnitee as to which such
Indemnitee has the right to reimbursement shall constitute Secured Obligations
secured by the Pledged Collateral.

         Modification in Writing.  No amendment, modification, supplement,
termination or waiver of or to any provision of this Agreement, nor consent to
any departure by the Pledgor therefrom, shall be effective unless the same
shall be done in accordance with the terms of the Credit Agreement and unless
in writing and signed by Collateral Agent and Pledgor.  Any amendment,
modification or supplement of or to any provision of this Agreement, any waiver
of any provision of this Agreement, and any consent to any departure by the
Pledgor from the terms





___________________________________________

of any provision of this Agreement, shall be effective only in the specific
instance and for the specific purpose for which made or given.  Except where
notice is specifically required by this Agreement or any other Credit Document,
no notice to or demand on the Pledgor in any case shall entitle any such
Pledgor to any other or further notice or demand in similar or other
circumstances.

         Termination; Release.  When all the Secured Obligations have been
indefeasibly paid in full and the Commitments of the Banks to make any Loan
under the Credit Agreement shall have expired, this Agreement shall terminate.
Upon termination of this Agreement or any release of Pledged Collateral in
accordance with the provisions of the Credit Agreement, Collateral Agent shall,
upon the request and at the sole cost and expense of the applicable Pledgor,
forthwith assign, transfer and deliver to such Pledgor, against receipt and
without recourse to or warranty by Collateral Agent, such of the Pledged
Collateral to be released (in the case of a release) as may be in the
possession of Collateral Agent and as shall not have been sold or otherwise
applied pursuant to the terms hereof, on the order of and at the sole cost and
expense of such Pledgor, and proper instruments (including UCC termination
statements on Form UCC-3) acknowledging the termination of this Agreement or
the release of such Pledged Collateral, as the case may be.

         Notices.  Unless otherwise provided herein or in the Credit Agreement,
any notice or other communication herein required or permitted to be given
shall be given in the manner set forth in the Credit Agreement; provided that
notices to Collateral Agent shall not be effective until received by Collateral
Agent.

         Continuing Security Interest; Assignment.  This Agreement shall create
a continuing security interest in the Pledged Collateral and shall (i) be
binding upon each Pledgor, its respective successors and assigns, and  (ii)
inure, together with the rights and remedies of Collateral Agent hereunder, to
the benefit of Collateral Agent and the other Secured Parties and each of their
respective successors, transferees and assigns; no other Persons (including,
without limitation, any other creditor of the Pledgor) shall have any interest
herein or any right or benefit with respect hereto.

Without limiting the generality of the foregoing clause (ii), any Bank may
assign or otherwise transfer any indebtedness held by it secured by this
Agreement to any other Person, and such other Person shall thereupon become
vested with all the benefits in respect thereof granted to such Bank, herein or
otherwise, subject however, to the provisions of the Credit Agreement.

         GOVERNING LAW; TERMS.  THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL
BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS, EXCEPT TO THE EXTENT
THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST HEREUNDER, OR REMEDIES
HEREUNDER, IN RESPECT OF ANY PLEDGED COLLATERAL ARE GOVERNED BY THE LAWS OF A
JURISDICTION OTHER THAN THE STATE OF NEW YORK.

         CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  ALL JUDICIAL
PROCEEDINGS BROUGHT AGAINST THE PLEDGOR WITH RESPECT TO THIS AGREEMENT MAY BE
BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE OF
NEW YORK AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT THE PLEDGOR ACCEPTS
FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND
UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS, AND
IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION
WITH THIS AGREEMENT.  THE PLEDGOR DESIGNATES AND APPOINTS CT CORPORATION
SYSTEM, WITH AN ADDRESS AT 1633 BROADWAY, NEW YORK, NEW YORK 10019, AND SUCH
OTHER PERSONS AS MAY HEREAFTER BE SELECTED BY THE PLEDGOR IRREVOCABLY AGREEING
IN WRITING TO SO SERVE, AS ITS AGENT TO RECEIVE ON ITS BEHALF, SERVICE OF ALL
PROCESS IN ANY SUCH PROCEEDINGS IN ANY SUCH COURT, SUCH SERVICE BEING HEREBY
ACKNOWLEDGED BY THE PLEDGOR TO BE EFFECTIVE AND BINDING SERVICE IN EVERY
RESPECT.  A COPY OF SUCH PROCESS SO SERVED SHALL BE MAILED BY REGISTERED MAIL
TO THE PLEDGOR AT ITS ADDRESS PROVIDED FOR IN SECTION 19 HEREOF EXCEPT THAT
UNLESS OTHERWISE PROVIDED BY APPLICABLE LAW, ANY FAILURE TO MAIL SUCH COPY
SHALL NOT AFFECT THE VALIDITY OF SERVICE OF PROCESS.  IF ANY AGENT APPOINTED BY
THE PLEDGOR REFUSES TO RECEIVE AND FORWARD SUCH SERVICE, THE PLEDGOR HEREBY
AGREES THAT SERVICE UPON IT BY MAIL SHALL CONSTITUTE SUFFICIENT NOTICE.
NOTHING HEREIN SHALL  AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER
PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF COLLATERAL AGENT TO BRING
PROCEEDINGS AGAINST PLEDGOR IN THE COURTS OF ANY OTHER JURISDICTION.

         Severability of Provisions.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction.

         Execution in Counterparts.  This Agreement and any amendments,
waivers, consents or supplements hereto may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed and delivered shall be deemed to be an original, but all
such counterparts together shall constitute one and the same agreement.

         Headings.  The Section headings used in this Agreement are for
convenience of reference only and shall not affect the construction of this
Agreement.

         Obligations Absolute.  All obligations of the Pledgor hereunder shall
be absolute and unconditional irrespective of:

         any bankruptcy, insolvency, reorganization, arrangement, readjustment,
    composition, liquidation or the like of the Pledgor or any other Credit
    Party;

         any lack of validity or enforceability of the Credit Agreement or any
    other Credit Document or any other agreement or instrument relating
    thereto;

         any change in the time, manner or place of payment of, or in any other
    term of, all or any of the Secured Obligations, or any other amendment or
    waiver of or any consent to any departure from the Credit Agreement, any
    other Credit Document or any other agreement or instrument relating
    thereto;

         any exchange, release or non-perfection of any other collateral, or
    any release or amendment or waiver of or





___________________________________________

___________________________________________

    consent to any departure from any guarantee, for all or any of the Secured
    Obligations;

         any exercise or non-exercise, or any waiver of any right, remedy,
    power or privilege under or in respect of this Agreement, or any other
    Credit Document except as specifically set forth in a waiver granted
    pursuant to the provisions of Section 17 hereof; or

         any other circumstances which might otherwise constitute a defense
    available to, or a discharge of, any other Pledgor.

         Collateral Agent's Right to Sever Indebtedness.

         The Pledgor acknowledges that (i) the Pledged Collateral does not
constitute the sole source of security for the payment and performance of the
Secured Obligations and that the Secured Obligations are also secured by other
types of property of such Pledgor and its Affiliates in other jurisdictions
(all such property, collectively, the "Collateral"), (ii) the number of such
jurisdictions and the nature of the transaction of which this instrument is a
part are such that it would have been impracticable for the parties to allocate
to each item of Collateral a specific loan amount and to execute in respect of
such item a separate credit agreement, and (iii) each Pledgor intends that
Collateral Agent have the same rights with respect to the Pledged Collateral,
in any judicial proceeding relating to the exercise of any right or remedy
hereunder or otherwise, that Collateral Agent would have had if each item of
collateral had been pledged or encumbered pursuant to a separate credit
agreement and security instrument.  In furtherance of such intent, each Pledgor
agrees to the greatest extent permitted by law that Collateral Agent may at any
time by notice (an "Allocation Notice") to the Pledgor allocate a portion of
the Secured Obligations (the "Allocated Indebtedness") to the Pledged
Collateral of such Pledgor and sever from the remaining Secured Obligations the
Allocated Indebtedness.  From and after the giving of an Allocation Notice with
respect to the Pledged Collateral, the Secured Obligations hereunder shall be
limited to the extent set forth in the Allocation Notice and (as so limited)
shall, for all purposes, be construed as a separate credit obligation




___________________________________________

<PAGE>   359
___________________________________________


of each Pledgor unrelated to the other transactions contemplated by the Credit
Agreement or any other Credit Document or any document related to either
thereof.  To the extent that the proceeds of any  judicial proceeding relating
to the exercise of any right or remedy hereunder of the Pledged Collateral
shall exceed the Allocated Indebtedness, such proceeds shall belong to such
Pledgor and shall not be available hereunder to satisfy any Secured Obligations
of such Pledgor other than the Allocated Indebtedness.  In any action or
proceeding to exercise any right or remedy under this Agreement which is
commenced after the giving by Collateral Agent of an Allocation Notice, the
Allocation Notice shall be conclusive proof of the limits of the Secured
Obligations hereby secured, and the Pledgor may introduce, by way of defense or
counterclaim, evidence thereof in any such action or proceeding.
Notwithstanding any provision of this Section 27, the proceeds received by
Collateral Agent pursuant to this Agreement shall be applied by Collateral
Agent in accordance with the provisions of Section 11 hereof.

         The Pledgor hereby waives to the greatest extent permitted under law
the right to a discharge of any of the Secured Obligations under any statute or
rule of law now or hereafter in effect which provides that the exercise of any
particular right or remedy as provided for herein (by judicial proceedings or
otherwise) constitutes the exclusive means for satisfaction of the Secured
Obligations or which makes unavailable any further judgment or any other right
or remedy provided for herein because Collateral Agent elected to proceed with
the exercise of such initial right or remedy or because of any failure by
Collateral Agent to comply with laws that prescribe conditions to the
entitlement to such subsequent judgment or the availability of such subsequent
right or remedy.  In the event that, notwithstanding the foregoing waiver, any
court shall for any reason hold that such subsequent judgment or action is not
available to Collateral Agent, no Pledgor shall (i) introduce in any other
jurisdiction any judgment so holding as a defense to enforcement against such
Pledgor of any remedy in the Credit Agreement or executed in connection with
the Credit Agreement or (ii) seek to have such judgment recognized or entered
in any other jurisdiction, and any such judgment shall in all events be limited
in application only to the state or jurisdiction where rendered and only with
respect to the collateral referred to in such judgment.

         In the event any instrument in addition to the Allocation Notice is
necessary to effectuate the provisions of this Section 27, including, without
limitation, any amendment to this Agreement, any substitute promissory note or
affidavit or certificate of any kind, Collateral Agent may execute and deliver
such instrument as the attorney-in-fact of the Pledgor.

         Notwithstanding anything set forth herein to the contrary, the
provisions of this Section 27 shall be effective only to the maximum extent
permitted by law.

         Future Advances.  This Agreement shall secure the payment of any
amounts advanced from time to time pursuant to the Credit Agreement.

         Facilitating Governmental Approvals; Specific Performance.

         In connection with the exercise by Collateral Agent of its rights
under this Agreement relating to the disposition of the Pledged Collateral as
it may affect the control of any Governmental License issued by the FCC or any
other authorizations, agreements, permits, licenses, and franchises of the
Pledgor, it may be necessary to obtain the prior consent or approval of the FCC
or other Governmental Authority to the exercise of Collateral Agent's rights
with respect to the Pledged Collateral.  To the extent that any such consent or
approval is required for any action that Collateral Agent may take under this
Agreement with respect to the Pledged Collateral, receipt of such FCC or
Governmental Authority approval shall be a condition precedent to Collateral
Agent's exercise of such rights.  In furtherance of the first sentence of this
Section, the Pledgor hereby agrees, at its own cost, to use its best efforts to
take any and all actions which Collateral Agent may request in order to obtain
such consents or approvals or any other governmental authorization as may be
necessary to enable Collateral Agent to exercise and enjoy the full rights and
benefits granted to it under this Agreement, the Credit Agreement, or any other
Credit Document, including, without limitation, the preparation, execution,
delivery or filing on the Pledgor's behalf and in such Pledgor's name, or in
such other name as may be appropriate or required, or causing to be prepared,
executed, delivered or filed, all

applications, certificates, filings, instruments, information, reports and
other documents (including, without limitation, any application for any
assignment or transfer of control or ownership).

         The Pledgor hereby acknowledges that a breach of any of its respective
obligations contained in this Agreement will cause irreparable injury to
Collateral Agent, and that such a breach would not be adequately compensable in
damages, and therefore Pledgors agree that their obligations under this
Agreement shall be specifically enforceable.
