     Alamosa is a holding company for our operating subsidiaries. Alamosa PCS,
Inc., Alamosa Wisconsin GP, LLC, Alamosa Wisconsin Limited Partnership, Alamosa
Delaware GP, LLC, and Texas Telecommunications, LP are all subsidiaries of
Alamosa. These subsidiaries have fully and unconditionally guaranteed, jointly
and severally, on a senior subordinated, unsecured basis, the obligations of
Alamosa  in connection with our sale of Alamosa's senior 12 7/8% discount notes
due 2010.

    ITEM 1. BUSINESS.

    References in this annual report on Form 10-K to Alamosa as a provider of
wireless personal communications services or similar phrases generally refer to
our building, owning and managing our portion of the Sprint PCS network pursuant
to our affiliation agreements with Sprint PCS. Sprint PCS holds the spectrum
licenses and controls the network through its agreements with us.

    All references contained in this annual report on Form 10-K to resident
population and residents are based on projections of year-end 1999 population
counts calculated by applying the annual growth rate from 1990 to 1998 to
estimates of 1998 population counts compiled by the U.S. Census Bureau.

OVERVIEW

    Alamosa is a provider of wireless personal communication services, commonly
referred to as PCS, in the southwestern and midwestern United States. We are a
network partner of Sprint PCS, the personal communications services group of
Sprint Corporation. Sprint PCS, directly and through affiliates such as us,
provides wireless services in more than 4,000 cities and communities across the
country. We have the exclusive right to provide digital wireless personal
communications services under the Sprint and Sprint PCS brand names in a
territory primarily located in Texas, New Mexico, Arizona, Colorado and
Wisconsin with approximately 8.4 million residents. We are a development stage
company with very limited operations, very limited revenues, significant losses,
substantial future capital requirements and an expectation of continued losses.

    We launched Sprint PCS service in Laredo in June 1999, and have since
commenced service in ten additional markets: Albuquerque, Santa Fe, El Paso, Las
Cruces, Lubbock, Amarillo, Midland, Odessa, Abilene and San Angelo. Our systems
cover approximately 2.7 million residents out of approximately 3.9 million total
residents in those markets. The number of residents covered by our systems does
not represent the number of Sprint PCS subscribers that we expect to be based in
our territory. As of December 31, 1999, 31,876 Sprint PCS subscribers were based
in our territory.

OUR BACKGROUND

    We were formed in July 1998 as a Texas limited liability company. Prior to
the closing of our initial public offering in February 2000, we were comprised
of Alamosa PCS LLC, a Texas limited liability company, Alamosa Wisconsin Limited
Partnership, a Wisconsin limited partnership, and a 99.75% owned subsidiary of
Alamosa PCS LLC, and Texas Telecommunications, LP, a Texas limited partnership,
and wholly-owned subsidiary of Alamosa PCS LLC. Immediately prior to the closing
of our initial public offering, we reorganized the business into a holding
company structure. The members of Alamosa PCS LLC received shares of common
stock of Alamosa PCS Holdings, Inc. in the same proportion to their membership
interests in Alamosa PCS, LLC.

    Alamosa PCS Holdings, Inc., a Delaware corporation, was formed in October
1999 to operate as a holding company. Texas Telecommunications, LP was formed in
December 1999. In connection with our reorganization, Texas Telecommunications,
LP received the assets of Alamosa PCS LLC related to operations in the southwest
United States and operated the business of Alamosa PCS LLC. Alamosa PCS, Inc.
held a 99% limited partnership interest in Texas Telecommunications, LP. Alamosa
Delaware GP, LLC, a wholly-owned subsidiary of Alamosa PCS, Inc., held a 1%
general partnership interest in Texas Telecommunications, LP.

    Alamosa Wisconsin Limited Partnership was formed in December 1999. In
connection with our reorganization, Alamosa Wisconsin Limited Partnership
received the assets of Alamosa PCS, LLC related to operations in Wisconsin.
After the reorganization, Alamosa Wisconsin Limited Partnership commenced our
business operations in Wisconsin. Alamosa PCS, Inc. holds a 98.75% voting
limited partnership interest and Chibardun Telephone Cooperative, Inc., a rural
telephone company in Wisconsin, owns a 0.25% non-voting limited partnership
interest in Alamosa Wisconsin Limited Partnership. Alamosa Wisconsin GP, LLC, a
wholly-owned subsidiary of Alamosa PCS, Inc., holds a 1% general partnership
interest in Alamosa Wisconsin Limited Partnership.

OUR RELATIONSHIP WITH SPRINT PCS

    Sprint is a diversified telecommunications service provider whose principal
activities include:

     o    long distance service;



                                       3
<PAGE>   5

     o    local service;

     o    wireless telephone products and services;

     o    product distribution and directory publishing activities; and

     o    other telecommunications activities, investments and alliances.

    Sprint PCS is a wholly-owned operating unit of Sprint and operates the only
100% digital wireless personal communications services network in the United
States with licenses to provide service nationwide using a single technology.
Sprint PCS has licenses to provide wireless service to an area containing over
270 million residents located throughout the United States, including Puerto
Rico and the U.S. Virgin Islands. The Sprint PCS network uses code division
multiple access technology nationwide.

STRATEGIC RELATIONSHIP WITH SPRINT PCS

    We are one of the largest affiliates of Sprint PCS based on the resident
population in our territory, and our territory adjoins several major Sprint PCS
markets. The build-out of our territory will significantly extend Sprint PCS's
coverage in the southwestern and midwestern United States. Due to our
relationship with Sprint PCS, we benefit from:

    Brand Recognition. We market products and services directly under the Sprint
and Sprint PCS brand names. We benefit from the recognizable Sprint and Sprint
PCS brand names and national advertising as we open markets. We offer pricing
plans, promotional campaigns and handset and accessory promotions of Sprint PCS.

    Existing Distribution Channels. We benefit from relationships with major
national retailers who distribute Sprint PCS products and services under
existing Sprint PCS contracts. These national retailers have approximately 470
retail outlets in our territory. Furthermore, we will benefit from sales made by
Sprint PCS to customers in our territory through its national telemarketing
sales force, national account sales team and Internet sales capability. These
existing distribution channels provide immediate access to customers as our
services become available in their area. For more information on our
distribution plan, see "-- Sales and Distribution."

    Sprint PCS's National Network. We offer access to Sprint PCS's wireless
network. Sprint PCS's network offers service in 280 major metropolitan areas
across the country. We expect to derive additional revenue from Sprint PCS when
its customers based outside of our territory roam on our portion of the Sprint
PCS network.

    High Capacity Network. Sprint PCS built its network around code division
multiple access digital technology, which we believe provides advantages in
capacity, voice-quality, security and handset battery life. For more information
on the benefits of this technology, see "-- Technology -- Code Division Multiple
Access Technology."

    Sprint PCS's Licensed Spectrum. Sprint PCS has invested approximately $100
million to purchase the wireless personal communications services licenses in
our territory and to pay costs to remove sources of microwave signals that
interfere with the licensed spectrum, a process generally referred to as
microwave clearing.

    Better Equipment Availability and Pricing. We expect to be able to acquire
handsets and network equipment more quickly and at a lower cost than we would
without our affiliation with Sprint PCS. For example, Sprint PCS will use
commercially reasonable efforts to obtain for us the same discounted
volume-based pricing on wireless-related products and warranties as Sprint PCS
receives from its vendors.

    Established Back Office Support Services. We have contracted with Sprint PCS
to provide critical back office services, including customer activation, handset
logistics, billing, customer care and network monitoring services. Because we do
not have to establish and operate our own systems, we are able to accelerate our
market launches and capitalize upon Sprint PCS's economies of scale.

    Access to the Sprint PCS Wireless Web. We support the recently announced
Sprint PCS Wireless Web service in our portion of the Sprint PCS network. For
more information on the Sprint PCS Wireless Web, see "-- Products and Services
- -- Access to the Sprint PCS Wireless Web."

    Pursuant to our affiliation agreements with Sprint PCS, we have agreed to
cover a minimum percentage of the resident population in our territory within
specified time periods. We plan to build-out our territory more rapidly than
those network build-out requirements. For more information on the network
build-out requirements, see "-- Our Affiliation Agreements with Sprint PCS:
The Management Agreement -- Network Build-Out." We believe that our build-out
plan is achievable based on our progress to date, the proven digital wireless
personal communications services technology we will use to build our portion of
the Sprint PCS network and the established standards of Sprint PCS. However, our
build-out plan may change for a number of reasons, including those described in
footnote (2) to the table above. See "Item 7. Management's Discussion and
Analysis of Financial Condition and Results of Operation" and "Financial
Statements" commencing on page F-1 hereof.

NETWORK OPERATIONS

GENERAL

    The effective operation of our portion of the Sprint PCS network requires:

    o public switched and long distance interconnection;

    o the implementation of roaming arrangements; and

    o the development of network monitoring systems.



                                       6
<PAGE>   8

    Our network connects to the public switched telephone network to facilitate
the origination and termination of traffic between our network and both local
exchange and long distance carriers. Sprint provides preferred rates for long
distance services. Through our arrangements with Sprint PCS and Sprint PCS's
arrangements with other wireless service providers, Sprint PCS subscribers based
in our territory have roaming capabilities on other networks. We have a network
monitoring system in our Lubbock switching center where we monitor our portion
of the Sprint PCS network during normal business hours. For after hours
monitoring, Sprint PCS's Network Operation Center provides 24 hour, seven day a
week monitoring of our portion of the Sprint PCS network and notification to our
designated personnel. This network monitoring process assists our staff in
improving our network reliability without having to staff 24 hours a day.

    As of December 31, 1999, our portion of the Sprint PCS network included 221
base stations and four switching centers. As of December 31, 2000, we anticipate
our portion of the Sprint PCS network will include 547 base stations and seven
switching centers.

NORTEL EQUIPMENT AGREEMENT

    On December 21, 1998, we entered into a three year agreement with Nortel
Networks, Inc., which was amended February 8, 2000, for our network equipment
and infrastructure, including switches, base stations and controllers. Pursuant
to the amended agreement, Nortel also provides installation and optimization
services, such as network engineering and radio frequency engineering, for the
equipment and granted to us a nonexclusive license to use all the software
associated with the Nortel equipment. During the term of the amended agreement
we have committed to purchase $167.0 million of equipment and services from
Nortel. Nortel finances these purchases pursuant to the Nortel credit facility
described in "Item 7. Management's Discussion and Analysis of Financial
Condition and Results of Operation -- Description of Our Indebtedness: The
Nortel Credit Facility." As of December 31, 1999, we have remaining commitments
of $117.6 million to purchase equipment and infrastructure under the amended
agreement. We submit purchase orders to Nortel for the equipment and services as
needed. Under the amended agreement, we receive a discount on the network
equipment and services because of our affiliation with Sprint PCS, but we must
pay a premium on any equipment and services financed by Nortel. At December 31,
1999, we were not obligated to pay this premium once we purchased an additional
$32.6 million in equipment and infrastructure under this amended agreement. If
our affiliation with Sprint PCS ends, Nortel has the right to either terminate
the agreement or, with our consent, modify the agreement to establish new
prices, terms and conditions.

TOWER AGREEMENT WITH SPECIALTY

    In August 1998, we entered into a nonexclusive master site development and
lease agreement for tower sites with Specialty Capital Services, Inc., now a
subsidiary of American Tower Corporation. Pursuant to the agreement, Specialty
arranges for collocation of our equipment, or constructs new facilities, in
areas we identify for build-out. Subject to our approval, Specialty provides
site acquisition, leasing and construction services and secures zoning,
permitting and surveying approvals and licenses for each base station location.
The initial term of the master agreement expires in August 2003, with automatic
renewal for three additional terms of five years each. We lease all individual
tower sites that Specialty provides for an initial term of five years, with
automatic renewals at our option for three additional terms of five years each.
We pay rental payments to Specialty monthly, in the amounts indicated on each
individual leased site schedule, subject to an annual adjustment based on the
Consumer Price Index. In any situation where Specialty's rights in a site are
derived from a lease with a third party, the terms of our agreement with
Specialty, including the lease term, are subordinate to the terms of that lease.

AGREEMENTS WITH CHR SOLUTIONS

    We have entered into a number of agreements with CHR Solutions to perform
aspects of our network build-out. CHR Solutions resulted from a merger between
Hicks & Ragland Engineering Co., Inc., and Cathey, Hutton & Associates, Inc.
effective as of November 1, 1999. Those agreements include the following:

    Engineering Service Contract. Pursuant to an engineering service contract
dated July 27, 1998, as amended, CHR Solutions performs design and construction
inspection services in connection with the deployment of switching centers and
base stations. The term of the contract covers three periods through August
2001, though either party may terminate the agreement for cause before August
2001. We pay CHR Solutions hourly rates for the employees who work on the
project as well as the employees' associated expenses. We also pay CHR Solutions
for the costs of test equipment and computer usage. The hourly rates and the
test equipment and computer usage costs are reviewed and modified by mutual
agreement annually until completion of the services or termination of the



                                       7
<PAGE>   9

agreement. A guaranteed maximum fee amount has been set for each period of the
contract, and those fees aggregate to approximately $7.0 million, excluding
taxes. If the total billing for the project is less than the guaranteed maximum
fee amount for the agreement, then we will pay an incentive bonus to CHR
Solutions equal to 50% of the difference.

    Data Communications Services Contract. We entered into a data communications
services contract with CHR Solutions as of April 9, 1999, for the design and
implementation of network interconnection systems for our local area networks
and wide area network. Similar to the engineering service contract, we pay CHR
Solutions hourly rates and test equipment and computer usage costs, subject to a
guaranteed maximum fee amount for the project of $262,040, excluding taxes. The
hourly rates and the test equipment and computer usage costs are reviewed and
modified by mutual agreement annually until completion of the services or
termination of the agreement. If the total billing for the project is less than
the guaranteed maximum fee amount, then we will pay an incentive bonus to CHR
Solutions equal to 50% of the difference. We may also require additional
services during the course of the contract and have been guaranteed a fee not to
exceed $50,000 for any of those services. The agreement lasts until the project
is completed, unless either CHR Solutions or we terminate it earlier for cause.

    Marketing and Operations Consulting Services Contract. Pursuant to a special
service contract, from September 20, 1998 through January 15, 1999, CHR
Solutions provided marketing and operations consulting services relating to the
setup and operation of our wireless personal communications services system.

    Wisconsin Marketing and Operations Consulting Services Contract. As of
October 8, 1999, we entered into a similar marketing and operations consulting
services contract with CHR Solutions relating to the setup and operation of the
wireless personal communications services system in selected areas in Wisconsin.
We pay CHR Solutions hourly rates for the employees who work on the project as
well as the employees' associated expenses. We also pay CHR Solutions for the
costs of computer usage. The hourly rates and computer usage costs are reviewed
and modified by mutual agreement annually until completion of the services or
termination of the agreement. The maximum fee for the services is not to exceed
$100,000, excluding taxes. The agreement lasts until the project is completed,
unless either party terminates it earlier.

    Business Planning and Consulting Services Contracts. Pursuant to a special
service contract dated as of October 8, 1999, CHR Solutions provides us with
business planning and consulting services and a feasibility study for selected
areas of Wisconsin for a fixed fee of $81,000. The agreement lasts until the
project is completed, unless either party terminates it earlier.

    We have entered into an additional special service contract with CHR
Solutions dated as of October 8, 1999. Pursuant to this contract, CHR Solutions
provides us with business planning and consulting services and a feasibility
study for additional selected areas in our territory. We pay CHR Solutions
hourly rates for the employees who work on the project as well as the employees'
associated expenses. We also pay CHR Solutions for the costs of computer usage.
The hourly rates and computer usage costs are reviewed and modified by mutual
agreement annually until completion of the services or termination of the
agreement. The estimated probable cost of the services is $200,000, excluding
taxes. The agreement lasts until the project is completed, unless either party
terminates it earlier.

    Radio Frequency "Drive Testing" Contract. Pursuant to a special service
contract dated as of October 8, 1999, CHR Solutions provides us with "drive
testing" to predict the radio frequency propagation characteristics of given
areas. We pay CHR Solutions hourly rates for the employees who work on the
project as well as the employees' associated expenses. We also pay CHR Solutions
for the costs of computer usage. The hourly rates and computer usage costs are
reviewed and modified by mutual agreement annually until completion of the
services or termination of the agreement. The estimated probable cost of the
services is $62,085, excluding taxes. The agreement lasts until the project is
completed, unless either party terminates it earlier.

    We offer products and services throughout our territory under the Sprint and
Sprint PCS brand names. Our products and services are designed to mirror the
service offerings of Sprint PCS and to integrate with the Sprint PCS network.
The Sprint PCS service packages we currently offer include the following:

PRICING AND FEATURES

    Sprint PCS's consumer pricing plans are typically structured with:

     o    monthly recurring charges;

     o    large local calling areas;

     o    bundles of minutes; and

     o    service features such as voicemail, caller ID, call waiting, call
          forwarding and three-way calling.

    The increased capacity of code division multiple access technology allows us
to market high usage customer plans at per minute rates lower than analog
cellular and certain digital providers. All of Sprint PCS's current national
plans:

     o    include minutes on any portion of the Sprint PCS network with no
          roaming charges for the customer;

     o    offer advanced features and generally require no long-term contracts;

     o    offer a selection of handsets to meet the needs of individual
          consumers and businesses;

     o    provide a limited-time money back guarantee on Sprint PCS handsets;
          and

     o    provide the first incoming minute free.

    In addition, Sprint PCS's "Free and Clear" calling plans include free long
distance calling from anywhere on its national network to anywhere in the United
States.

ADVANCED HANDSETS

    We offer a selection of single and dual-band handsets with various advanced
features and technology, such as Internet readiness described in "-- Access to
the Sprint PCS Wireless Web" above. All handsets are sold under the Sprint and
Sprint PCS brand names and are equipped with preprogrammed features such as:

     o    caller ID;

     o    call waiting;



                                       9
<PAGE>   11

     o    phone books;

     o    speed dial; and

     o    last number redial.

    Code division multiple access single-band/single-mode handsets, weighing
approximately five to seven ounces, offer up to five days of standby time and
approximately four hours of talk time. We also offer dual-band/dual-mode
handsets that allow customers to make and receive calls on both wireless
personal communications services and cellular frequency bands with the
applicable digital or analog technology. These handsets allow roaming on
cellular networks where Sprint PCS digital service is not available.

PRIVACY AND SECURITY

    Sprint PCS provides voice transmissions encoded into a digital format with a
significantly lower risk of fraud and eavesdropping than on analog-based
systems. Sprint PCS customers using dual-band/dual-mode handsets in analog mode
do not have the benefit of digital security.

SIMPLE ACTIVATION

    Customers can purchase a Sprint PCS handset at a retail location and
activate their service and program the handset by calling Sprint PCS customer
care.

CUSTOMER CARE

    Sprint PCS provides customer care services to customers based in our
territory under our services agreement. Sprint PCS offers customer care 24 hours
a day, seven days a week. Customers can call the Sprint PCS toll-free customer
care number from anywhere in the country. All Sprint PCS handsets are
preprogrammed with a speed dial feature that allows customers to easily reach
customer care at any time.

OTHER SERVICES

    In addition to these services, we may also offer wireless local loop
services in our territory, but only where Sprint is not a local exchange
carrier. Wireless local loop is a wireless substitute for the landline-based
telephones in homes and businesses. We also believe that new features and
services will be developed on the Sprint PCS network to take advantage of code
division multiple access technology. Sprint PCS conducts ongoing research and
development to produce innovative services that are intended to give Sprint PCS
a competitive advantage. We may incur additional expenses in modifying our
technology to provide these additional features and services.

ROAMING

SPRINT PCS ROAMING

    Sprint PCS roaming includes both inbound Sprint PCS roaming, when a Sprint
PCS subscriber based outside of our territory uses our portion of the Sprint PCS
network, and outbound Sprint PCS roaming, when a Sprint PCS subscriber based in
our territory uses the Sprint PCS network outside of our territory. Sprint PCS
pays us a per minute fee for inbound Sprint PCS roaming. Similarly, we pay a per
minute fee to Sprint PCS for outbound Sprint PCS roaming. Pursuant to our
affiliation agreements with Sprint PCS, Sprint PCS has the discretion to change
the per minute rate for Sprint PCS roaming fees.



                                       10
<PAGE>   12

NON-SPRINT PCS ROAMING

    Non-Sprint PCS roaming includes both inbound non-Sprint PCS roaming, when a
non-Sprint PCS subscriber uses our portion of the Sprint PCS network, and
outbound non-Sprint PCS roaming, when a Sprint PCS subscriber based in our
territory uses a non-Sprint PCS network. Pursuant to roaming agreements between
Sprint PCS and other wireless service providers, when another wireless service
provider's subscriber uses our portion of the Sprint PCS network, we earn
inbound non-Sprint PCS roaming revenue. These wireless service providers must
pay fees for their subscribers' use of our portion of the Sprint PCS network,
and as part of our collected revenues, we are entitled to 92% of these fees.
Currently, pursuant to our services agreement with Sprint PCS, Sprint PCS bills
these wireless service providers for these fees. When another wireless service
provider provides service to one of the Sprint PCS subscribers based in our
territory, we pay outbound non-Sprint PCS roaming fees directly to that
provider. Sprint PCS, pursuant to our current services agreement with Sprint
PCS, then bills the Sprint PCS subscriber for use of that provider's network at
rates specified in his or her contract and pays us 100% of this outbound
non-Sprint PCS roaming revenue collected from that subscriber on a monthly
basis. As a result, we retain the collection risk for outbound non-Sprint PCS
roaming fees incurred by the subscribers based in our territory.

MARKETING STRATEGY

    Our marketing strategy is to complement Sprint PCS's national marketing
strategies with techniques tailored to each of the specific markets in our
territory.

USE SPRINT PCS'S BRAND EQUITY

    We feature exclusively and prominently the nationally recognized Sprint and
Sprint PCS brand names in our marketing and sales effort. From the customers'
point of view, they use our portion of the Sprint PCS network and the rest of
the Sprint PCS network as a unified national network.

ADVERTISING AND PROMOTIONS

    Sprint PCS promotes its products through the use of national as well as
regional television, radio, print, outdoor and other advertising campaigns. In
addition to Sprint PCS's national advertising campaigns, we advertise and
promote Sprint PCS products and services on a local level in our markets at our
cost. We have the right to use any promotion or advertising materials developed
by Sprint PCS and only have to pay the incremental cost of using those
materials, such as the cost of local radio and television advertisement
placements, advertisement production and material costs and incremental printing
costs. We also benefit from any advertising or promotion of Sprint PCS products
and services by third party retailers in our territory, such as RadioShack,
Circuit City and Best Buy. We must pay the cost of specialized Sprint PCS print
advertising by third party retailers. Sprint PCS also runs numerous promotional
campaigns which provide customers with benefits such as additional features at
the same rate or free minutes of use for limited time periods. We offer these
promotional campaigns to potential customers in our territory.

SPONSORSHIPS

    Sprint PCS is a sponsor of numerous national, regional and local events.
These sponsorships provide Sprint PCS with brand name and product recognition in
high profile events and provide a forum for sales and promotions. Additionally,
we have been a sponsor for events and activities in our territory such as:

     o    the Albuquerque Balloon Fest;

     o    the Western Professional Hockey League;

     o    minor league baseball teams;

     o    local school programs;

     o    March of Dimes; and

     o    other charity events.

BUNDLING OF SERVICES

    We expect to take advantage of the complete array of communications services
offered by Sprint PCS and Sprint, which may include bundling wireless personal
communications services with other Sprint products, such as long distance and
Internet access.

SALES FORCE WITH LOCAL PRESENCE

    We have established local sales forces to execute our marketing strategy
through direct business-to-business contacts, our company-owned retail stores,
local distributors and other channels. In addition, we have targeted
maquiladoras, which are factories with locations on both sides of the border,
and the numerous college campuses in our territory. Our market teams also
participate in local clubs and civic organizations such as the Chamber of
Commerce, Rotary and Kiwanis.

SALES AND DISTRIBUTION

    Our sales and distribution plan is designed to exploit Sprint PCS's multiple
channel sales and distribution plan and to enhance it through the development of
local distribution channels. Key elements of our sales and distribution plan
consist of the following:

SPRINT PCS RETAIL STORES

    As of December 31, 1999, we owned and operated 13 Sprint PCS stores and two
kiosks at military base locations. These stores provide us with a local presence
and visibility in the markets within our territory. Following the Sprint PCS
model, these stores are designed to facilitate retail sales, activation, bill
collection and customer service, although we currently do not have direct
electronic access to Sprint PCS customer care at these stores. We plan to add
ten new stores and three kiosks by year-end 2000 and another six new stores and
three kiosks by year-end 2001.

SPRINT STORE WITHIN A RADIOSHACK STORE

    Sprint has an exclusive arrangement with RadioShack to install a "store
within a store," making Sprint PCS the exclusive brand of wireless personal
communications services using CDMA technology in the 1900 MHz spectrum and
products sold through RadioShack stores. As of December 31, 1999, RadioShack had
approximately 225 stores in our territory.

OTHER NATIONAL THIRD PARTY RETAIL STORES

    In addition to RadioShack, we benefit from the distribution agreements
established by Sprint PCS with other national and regional retailers which
currently include:

     o    Best Buy;                          o    K-Mart;

     o    Circuit City;                      o    Dillard's;

     o    Office Depot;                      o    Montgomery Ward;

     o    Office Max;                        o    Foley's;

     o    Staples;                           o    Ritz Camera; and

     o    Heilig Meyer;                      o    selected May Company
                                                  department stores.
     o    Target;



As of December 31, 1999, these retailers had approximately 240 stores in our
territory.

                                       12

NATIONAL ACCOUNTS AND DIRECT SELLING

    We participate in Sprint PCS's national accounts program. Sprint PCS has a
national accounts team, which focuses on the corporate headquarters of large
companies. Once a representative reaches an agreement with the corporate
headquarters, we service the offices of that corporation located in our
territory. Our direct sales force targets the employees of these corporations in
our territory and contacts other local business clients.

TELEMARKETING

    Sprint PCS provides telemarketing sales when customers call from our
territory. As the exclusive provider of Sprint PCS products and services in our
market, we will benefit from the national Sprint PCS 1-800-480-4PCS number
campaigns that generate call-in leads. These leads are then handled by Sprint
PCS's inbound telemarketing group.

ELECTRONIC COMMERCE

    Sprint PCS maintains an Internet site, www.sprintpcs.com, which contains
information on Sprint PCS products and services. A visitor to Sprint PCS's
Internet site can order and pay for a handset and select a rate plan. Sprint PCS
customers visiting the site can review the status of their account, including
the number of minutes used in the current billing cycle. We will recognize the
revenues generated by Sprint PCS customers in our territory who purchase
products and services over the Sprint PCS Internet site.

SEASONALITY

    Our business is subject to seasonality because the wireless industry is
heavily dependent on fourth quarter results. Among other things, the industry
relies on significantly higher customer additions and handset sales in the
fourth quarter as compared to the other three fiscal quarters. A number of
factors contribute to this trend, including:

     o    the increasing use of retail distribution, which is dependent upon the
          year-end holiday shopping season;

     o    the timing of new product and service announcements and introductions;

     o    competitive pricing pressures; and

     o    aggressive marketing and promotions.

TECHNOLOGY

GENERAL

    In the commercial wireless communication industry there are two principal
services licensed by the Federal Communications Commission for transmitting
two-way, real time voice and data signals: "cellular" and wireless "personal
communications services." In addition, enhanced specialized mobile radio
service, a new but not yet widely used technology, also allows for
interconnected two-way real time voice and data services. The Federal
Communications Commission licenses these applications, each of which operates in
a distinct radio frequency block. Cellular, which uses the 800 MHz frequency
block, was the original form of widely-used commercial wireless voice
communications. Cellular systems are predominantly analog-based, but over the
last several years cellular operators have started to use digital service in the
800 MHz frequency block. Digital services have been deployed, as a complement to
the analog based services, in most of the major metropolitan markets.

    In 1993, the Federal Communications Commission allocated the 1900 MHz
frequency block of the radio spectrum for wireless personal communications
services. Wireless personal communications services differ from traditional
analog cellular telephone service principally in that wireless personal
communications services systems operate at a higher frequency and employ
advanced digital technology. Analog-based systems send signals in which the
transmitted signal resembles the input signal, the caller's voice. Digital
systems convert voice or data signals into a stream of digits that permit a
single radio channel to carry multiple simultaneous transmissions. Digital
systems also achieve greater frequency reuse than analog systems resulting in
greater capacity than analog systems. This enhanced capacity, along with
enhancements in digital protocols, allows digital-based wireless technologies,
whether using wireless personal communications services or cellular frequencies,
to offer new and enhanced



                                       13
<PAGE>   15

services, including greater call privacy and more robust data transmission, such
as facsimile, electronic mail and connecting notebook computers with
computer/data networks.

    Wireless communications systems, whether wireless personal communications
services or cellular, are divided into multiple geographic coverage areas, known
as "cells." In both wireless personal communications services and cellular
systems, each cell contains a transmitter, a receiver and signaling equipment,
known as the "base station." The base station is connected by microwave or
landline telephone lines to a switch that uses computers to control the
operation of the cellular or wireless personal communications services system.
The system:

     o    controls the transfer of calls from cell to cell as a subscriber's
          handset travels;

     o    coordinates calls to and from handsets;

     o    allocates calls among the cells within the system; and

     o    connects calls to the local landline telephone system or to a long
          distance carrier.

    Wireless communications providers establish interconnection agreements with
local exchange carriers and interexchange carriers, thereby integrating their
system with the existing landline communications system. Because the signal
strength of a transmission between a handset and a base station declines as the
handset moves away from the base station, the switching office and the base
station monitor the signal strength of calls in progress. When the signal
strength of a call declines to a predetermined level, the switching office may
"hand off" the call to another base station where the signal strength is
stronger.

    Wireless digital signal transmission is accomplished through the use of
various forms of frequency management technology or "air interface protocols."
The Federal Communications Commission has not mandated a universal air interface
protocol for wireless personal communications services systems. Wireless
personal communications systems operate under one of three principal air
interface protocols, code division multiple access, time division multiple
access, commonly referred to as TDMA, or global system for mobile
communications, commonly referred to as GSM. Time division multiple access and
global system for mobile communications are both time division multiple access
systems but are incompatible with each other. The code division multiple access
system is incompatible with both global system for mobile communications and
time division multiple access systems. Accordingly, a subscriber of a system
that utilizes code division multiple access technology is unable to use a code
division multiple access handset when traveling in an area not served by code
division multiple access-based wireless personal communications services
operators, unless the customer carries a dual-band/dual-mode handset that
permits the customer to use the analog cellular system in that area. The same
issue would apply to users of time division multiple access or global system for
mobile communications systems. All of the wireless personal communications
services operators now have dual-mode or tri-mode handsets available to their
customers. Because digital networks do not cover all areas in the country, these
handsets will remain necessary for segments of the subscriber base.

CODE DIVISION MULTIPLE ACCESS TECHNOLOGY

    Sprint PCS's network and its affiliates' networks all use digital code
division multiple access technology. We believe that code division multiple
access provides important system performance benefits such as:

    Greater capacity. We believe, based on studies by code division multiple
access manufacturers, that code division multiple access systems can provide
system capacity that is approximately seven to ten times greater than that of
current analog technology and approximately three times greater than time
division multiple access and global system for mobile communications systems.

    Privacy and security. One of the benefits of code division multiple access
technology is that it combines a constantly changing coding scheme with a low
power signal to enhance call security and privacy.

    Soft hand-off. Code division multiple access systems transfer calls
throughout the code division multiple access network using a technique referred
to as a soft hand-off, which connects a mobile customer's call with a new base
station while maintaining a connection with the base station currently in use.
Code division multiple access networks monitor the quality of the transmission
received by multiple base stations simultaneously to select a better
transmission path and to ensure that the network does not disconnect the call in
one cell unless replaced by a



                                       14
<PAGE>   16

stronger signal from another base station. Analog, time division multiple access
and global system for mobile communications networks use a "hard hand-off" and
disconnect the call from the current base station as it connects with a new one
without any simultaneous connection to both base stations.

    Simplified frequency planning. Frequency planning is the process used to
analyze and test alternative patterns of frequency used within a wireless
network to minimize interference and maximize capacity. Unlike time division
multiple access and global system for mobile communications based systems, code
division multiple access based systems can reuse the same subset of allocated
frequencies in every cell, substantially reducing the need for costly frequency
reuse patterning and constant frequency plan management.

    Longer battery life. Due to their greater efficiency in power consumption,
code division multiple access handsets can provide longer standby time and more
talk time availability when used in the digital mode than handsets using
alternative digital or analog technologies.

    While code division multiple access has the inherent benefits discussed
above, time division multiple access networks are generally less expensive when
overlaying existing analog systems since the time division multiple access
spectrum usage is more compatible with analog spectrum planning. In addition,
global system for mobile communications technology, unlike code division
multiple access, allows multi-vendor equipment to be used in the same network.
This, along with the fact that the global system for mobile communications
technology is currently more widely used throughout the world than code division
multiple access, provides economies of scale for handset and equipment
purchases. A standards process is also underway which will allow wireless
handsets to support analog, time division multiple access and global system for
mobile communications technologies in a single unit. Currently, there are no
plans to have code division multiple access handsets that support either the
time division multiple access or global system for mobile communications
technologies.

COMPETITION

    Competition in the wireless communications services industry is intense. We
compete with a number of wireless service providers in our markets. We believe
that our primary competition is with national wireless providers such as:

     o    Nextel Communications, Inc.;

     o    AT&T Wireless Services, Inc.;

     o    the company that will result from the pending merger between Bell
          Atlantic Corp. and GTE Corp.; and

     o    Bell Atlantic Corp.-GTE Corp.'s recently announced partnership with
          Vodafone AirTouch Plc.

     We also compete with regional wireless providers. The principal regional
wireless competitors are:

     o    SBC Communications Inc. and Ameritech Corporation, its wholly-owned
          subsidiary;

     o    VoiceStream Wireless Corporation; and

     o    United States Cellular Corporation.

     Furthermore, a number of wireless service providers compete with us on a
local basis, such as:

     o    Airadigm Communications;

     o    Poka Lambro PCS, Inc.; and

     o    Amarillo CellTelCo.


                                       15
<PAGE>   17

    We also face competition from resellers, which provide wireless services to
customers but do not hold Federal Communications Commission licenses or own
facilities. Instead, the resellers buy blocks of wireless telephone numbers and
capacity from a licensed carrier and resell services through their own
distribution network to the public. The Federal Communications Commission
currently requires all cellular and wireless personal communications services
licensees to permit resale of carrier services to a reseller.

    In addition, we compete with existing communications technologies such as
paging, enhanced specialized mobile radio service dispatch and conventional
landline telephone companies in our markets. Potential users of wireless
personal communications services systems may find their communications needs
satisfied by other current and developing technologies. One or two-way paging or
beeper services that feature voice messaging and data display as well as
tone-only service may be adequate for potential customers who do not need to
speak to the caller.

    In the future, we expect to face increased competition from entities
providing similar services using other communications technologies, including
satellite-based telecommunications and wireless cable systems. While some of
these technologies and services are currently operational, others are being
developed or may be developed in the future.

    Many of our competitors have access to more licensed spectrum than the 10
MHz licensed to Sprint PCS in New Mexico and Durango and the 20 MHz licensed to
Sprint PCS in El Paso. Among other things, increased spectrum allows for higher
call volume and fewer dropped calls. Cellular service providers have licenses
covering 25 MHz of spectrum, and three competing wireless personal
communications services providers have licenses to use 30 MHz in New Mexico.
Except for New Mexico (10 MHz), Durango (10 MHz) and El Paso (20 MHz), Sprint
PCS has licenses to use 30 MHz of spectrum throughout our territory.

    Many of our competitors have significantly greater financial and technical
resources and subscriber bases than we do. AT&T Wireless has over 11 million
subscribers and the recent partnership of Bell Atlantic-GTE and Vodafone
AirTouch has over 19 million combined subscribers. Some of our competitors also
have established infrastructures, marketing programs and brand names. In
addition, some of our competitors may be able to offer regional coverage in
areas not served by the Sprint PCS network, or, because of their calling volumes
or relationships with other wireless providers, may be able to offer regional
roaming rates that are lower than those we offer. Wireless personal
communications services operators will likely compete with us in providing some
or all of the services available through the Sprint PCS network and may provide
services that we do not. Additionally, we expect that existing cellular
providers will continue to upgrade their systems to provide digital wireless
communication services competitive with Sprint PCS. Recently, there has been a
trend in the wireless communications industry towards consolidation of wireless
service providers through joint ventures, mergers and acquisitions. We expect
this consolidation to lead to larger competitors over time. These larger
competitors may have substantial resources or may be able to offer a variety of
services to a large customer base.

    Over the past several years the Federal Communications Commission has
auctioned and will continue to auction large amounts of wireless spectrum that
could be used to compete with Sprint PCS services. Based upon increased
competition, we anticipate that market prices for two-way wireless services
generally will decline in the future. We will compete to attract and retain
customers principally on the basis of:

     o    the strength of the Sprint and Sprint PCS brand names, services and
          features;

     o    the size of our territory;

     o    the location of our markets;

     o    our network coverage and reliability;

     o    customer care; and

     o    pricing.


                                       16
<PAGE>   18

Our ability to compete successfully will also depend, in part, on our ability to
anticipate and respond to various competitive factors affecting the industry,
including:

     o    new services and technologies that may be introduced;

     o    changes in consumer preferences;

     o    demographic trends;

     o    economic conditions; and

     o    discount pricing strategies by competitors.

    Our environmental compliance expenditures primarily result from the
operation of standby power generators for our telecommunications equipment and
compliance with various environmental rules during network build-out and
operations. The expenditures arise in connection with standards compliance or
permits which are usually related to generators, batteries or fuel storage. Our
environmental compliance expenditures have not been material to our financial
statements or to our operations and are not expected to be material in the
future.

EMPLOYEES

    As of December 31, 1999, we employed 182 full-time employees. None of our
employees are represented by a labor union. We believe that our relations with
our employees are good.

OUR AFFILIATION AGREEMENTS WITH SPRINT PCS

    Our four major agreements with Sprint and Sprint PCS, are:

     o    the management agreement;

     o    the services agreement; and

     o    two trademark and service mark license agreements with different
          Sprint entities.

    We entered into one set of these four major agreements with Sprint and
Sprint PCS for our territory in the southwestern part of the United States and
we entered into another set of these four major agreements for our territory in
Wisconsin. The following is a description of the material terms and provisions
of our affiliation agreements with Sprint PCS and the consent and agreement with
Nortel modifying the Sprint PCS management agreement. Unless otherwise indicated
below, the description of our affiliation agreements applies to the affiliation
agreements for both of our territories.



                                       17
<PAGE>   19

    Under our affiliation agreements with Sprint PCS, we have the exclusive
right to provide wireless services under the Sprint and Sprint PCS brand names
in our territory. We have recently amended our affiliation agreements with
Sprint PCS to include additional markets in our territory. Sprint PCS holds the
spectrum licenses and controls the network through its agreements with us. Our
affiliation agreements with Sprint PCS require us to interface with the Sprint
PCS wireless network by building our portion of the Sprint PCS network to
operate on the 10, 20 or 30 MHz of wireless personal communications services
frequencies licensed to Sprint PCS in the 1900 MHz range. The management
agreement has an initial term of 20 years with three 10-year renewal options,
which would lengthen the contract to a total term of 50 years. The three 10-year
renewal terms automatically occur unless we or Sprint PCS provide the other with
two years prior written notice to terminate the agreements or unless we are in
material default of our obligations under the agreements.

    In addition, we have entered into a consent and agreement with Sprint PCS
and Nortel that modifies the management agreement for the benefit of Nortel and
the holders of any refinancing of the Nortel indebtedness. See "Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operation -- Consent and Agreement for the Benefit of the Holders of the Nortel
Financing." Also, Sprint PCS has agreed to propose modifications to the
management agreement, and perhaps the other affiliation agreements, to enhance
our ability to obtain financing for our territory.

OUR AFFILIATION AGREEMENTS WITH SPRINT PCS:  THE MANAGEMENT AGREEMENT

    Under our management agreement with Sprint PCS, we have agreed to:

     o    own, construct and manage a wireless personal communications services
          network in our territory in compliance with Federal Communications
          Commission license requirements and other technical requirements
          contained in the management agreement;

     o    distribute Sprint PCS products and services;

     o    use Sprint PCS's and our own distribution channels in our territory;

     o    conduct advertising and promotion activities in our territory; and

     o    manage that portion of Sprint PCS's customer base assigned to our
          territory.

    Sprint PCS will supervise our wireless personal communications services
network operations and has the right to unconditional access to our portion of
the Sprint PCS network, including the right to test and monitor any of our
facilities and equipment.

EXCLUSIVITY

    We are designated as the only person or entity that can manage or operate a
wireless personal communications services network for Sprint PCS in our
territory. Sprint PCS is prohibited from owning, operating, building or managing
another wireless communications network in our territory while our management
agreement is in place and no event has occurred that would permit the agreement
to terminate. Sprint PCS is permitted to make national sales to companies in our
territory and, as required by the Federal Communications Commission, to permit
resale of the Sprint PCS products and services in our territory. The management
agreement prohibits us from interfering with others who resell Sprint PCS
products and services in our territory. If Sprint PCS decides to expand the
geographic size of our build-out, Sprint PCS must provide us with written notice
of the proposed expansion. We have a 90 day right of first refusal to build-out
the proposed area. If we choose not to build-out of the proposed area, then
Sprint PCS may build-out the area itself or allow another Sprint PCS network
partner to do so.

NETWORK BUILD-OUT

    The management agreement specifies the terms of the Sprint PCS affiliation,
including the required network build-out plan. We have agreed to cover a
specified percentage of the population within each of the markets which make up
our territory by specified dates. Our current build-out plan will satisfy the
network build-out requirements set forth in the management agreement. If
technically feasible and commercially reasonable, we have agreed to provide for
a seamless handoff of a call initiated in our territory to a neighboring Sprint
PCS network. The




                                       18
<PAGE>   20

management agreement requires us to reimburse Sprint PCS one-half of the
microwave clearing costs for our territory.

PRODUCTS AND SERVICES

    The management agreement identifies the products and services that we can
offer in our territory. These services include, but are not limited to, Sprint
PCS consumer and business products and services available as of the date of the
agreement, or as modified by Sprint PCS. We are allowed to sell wireless
products and services that are not Sprint PCS products and services if those
additional products and services do not cause distribution channel conflicts or,
in Sprint PCS's sole determination, consumer confusion with Sprint PCS's
products and services. We also cannot sell non-Sprint PCS products and services
if it would hamper our build-out of the network. Under the Wisconsin management
agreement, if Sprint PCS begins to offer nationally a product or service that we
already offer, then that product or service will be considered to be a Sprint
PCS product or service.

    We may also sell services such as specified types of long distance service,
Internet access, handsets, and prepaid phone cards with Sprint, Sprint PCS and
other Sprint PCS affiliates. If we decide to use third parties to provide these
services, we must give Sprint PCS an opportunity to provide the services on the
same terms and conditions. We cannot offer wireless local loop services
specifically designed for the competitive local exchange market in areas where
Sprint owns the local exchange carrier unless we name the Sprint-owned local
exchange carrier as the exclusive distributor or Sprint PCS approves the terms
and conditions. Sprint does not own the local exchange carrier in a majority of
the markets in our territory.

NATIONAL SALES PROGRAMS

    We must participate in the Sprint PCS sales programs for national sales to
customers, and will pay the expenses and receive the compensation from Sprint
PCS sales to national accounts located in our territory. We must use Sprint's
long distance service, which we can buy at the best prices offered to comparably
situated Sprint customers.

SERVICE PRICING, ROAMING AND FEES

    We must offer Sprint PCS subscriber pricing plans designated for regional or
national offerings, including Sprint PCS's "Free and Clear" plans. We are
permitted to establish our own local price plans for Sprint PCS's products and
services offered only in our territory, subject to Sprint PCS's approval. We are
entitled to receive a weekly fee from Sprint PCS equal to 92% of "collected
revenues" for all obligations under the management agreement, adjusted by the
cost of customer services provided by Sprint PCS. "Collected revenues" include
revenue from Sprint PCS subscribers based in our territory and inbound
non-Sprint PCS roaming. Sprint PCS will retain 8% of the collected revenues.
Outbound non-Sprint PCS roaming revenue, inbound and outbound Sprint PCS roaming
fees, proceeds from the sales of handsets and accessories, proceeds from sales
not in the ordinary course of business, amounts collected with respect to taxes
and, for our Wisconsin territory only, proceeds from sales of our products and
services, are not considered collected revenues. Except in the case of taxes, we
will retain 100% of these revenues. Many Sprint PCS subscribers purchase bundled
pricing plans that allow Sprint PCS roaming anywhere on the Sprint PCS network
without incremental Sprint PCS roaming charges. However, we will earn Sprint PCS
roaming revenue for every minute that a Sprint PCS subscriber from outside our
territory enters our territory and uses our services. We will earn revenue from
Sprint PCS based on a per minute rate established by Sprint PCS when Sprint
PCS's or its affiliates' subscribers roam on our portion of the Sprint PCS
network. Similarly, we will pay the same rate for every minute Sprint PCS
subscribers who are based in our territory use the Sprint PCS network outside
our territory. The analog roaming rate onto a non-Sprint PCS provider's network
is set under Sprint PCS's third party roaming agreements.

VENDOR PURCHASE AGREEMENTS

    We may participate in discounted volume-based pricing on wireless-related
products and warranties Sprint PCS receives from its vendors. Sprint PCS will
use commercially reasonable efforts to obtain for us the same prices as Sprint
PCS receives from its vendors.

ADVERTISING AND PROMOTIONS

    Sprint PCS uses national as well as regional television, radio, print,
outdoor and other advertising campaigns to promote its products. We benefit from
the national advertising at no additional cost to us. In addition to Sprint


                                       19
<PAGE>   21

PCS's national advertising campaigns, we advertise and promote Sprint PCS
products and services on a local level in our markets at our cost. We have the
right to use any promotion or advertising materials developed by Sprint PCS and
only have to pay the incremental cost of using those materials, such as the cost
of local radio and television advertisement placements and incremental printing
costs. Sprint PCS also runs numerous promotional campaigns which provide
customers with benefits such as additional features at the same rate or free
minutes of use for limited time periods. We offer these promotional campaigns to
potential customers in our territory.

PROGRAM REQUIREMENTS

    We must comply with Sprint PCS's program requirements for technical
standards, customer service standards, roaming coverage and national and
regional distribution and national accounts programs. Sprint PCS will use
commercial reasonableness to adjust the program requirements for cities located
within our territory that have a population of less than 100,000. Sprint PCS can
adjust the program requirements at any time. We have the right to appeal to
management of Sprint PCS if adjustments to program requirements will:

     o    cause us to incur a cost exceeding 5% of the sum of our stockholders'
          equity plus our outstanding long term debt; or

     o    cause our operating expenses on a per-unit basis using a ten year time
          frame to increase by more than 10% on a net present value basis.

    If Sprint PCS denies our appeal and we fail to comply with the program
adjustment, Sprint PCS has the termination rights described below.

NON-COMPETITION

    We may not offer Sprint PCS products and services outside our territory
without the prior written approval of Sprint PCS. Within our territory we may
offer, market or promote telecommunications products and services only under the
Sprint PCS brands, our own brand, brands of related parties of ours or other
products and services approved under the management agreement, except that no
brand of a significant competitor of Sprint PCS or its related parties may be
used for those products and services. To the extent we have or obtain licenses
to provide wireless personal communications services outside our territory, we
may not use the spectrum to offer Sprint PCS products and services without prior
written consent from Sprint PCS.

INABILITY TO USE NON-SPRINT PCS BRAND

    We may not market, promote, advertise, distribute, lease or sell any of the
Sprint PCS products and services on a non-branded, "private label" basis or
under any brand, trademark or trade name other than the Sprint PCS brand, except
for sales to resellers or as otherwise permitted under the trademark and service
mark license agreements.

TRANSFER OF SPRINT PCS NETWORK

    Sprint PCS can sell, transfer or assign its wireless personal communications
services network to a third party if the third party agrees to be bound by the
terms of the management agreement and the services agreement.

CHANGE IN CONTROL

    Sprint PCS must approve a change in control of Alamosa, but this consent
cannot be unreasonably withheld.

RIGHTS OF FIRST REFUSAL

    Sprint PCS has rights of first refusal, without further stockholder
approval, to buy our assets upon a proposed sale of all or substantially all of
our assets used in the operation of our portion of the Sprint PCS network.

TERMINATION OF MANAGEMENT AGREEMENT

    The management agreement can be terminated as a result of the following
events:

     o    termination of Sprint PCS's spectrum licenses;


                                       20
<PAGE>   22

     o    an uncured breach under the management agreement;

     o    bankruptcy of a party to the management agreement;

     o    the management agreement not complying with any applicable law in any
          material respect; or

     o    the termination of either of the trademark and service mark license
          agreements.

     The termination or non-renewal of the management agreement triggers some of
our rights and those of Sprint PCS. The right of either party to require the
other to purchase or sell the operating assets is discussed below.

     If we have the right to terminate the management agreement because of an
event of termination caused by Sprint PCS, generally we may:

     o    require Sprint PCS to purchase all of our operating assets used in
          connection with our portion of the Sprint PCS network for an amount
          equal to at least 80% of our Entire Business Value as defined below;

     o    in all areas in our territory where Sprint PCS is the licensee for 20
          MHz or more of the spectrum on the date we terminate the management
          agreement, require Sprint PCS to assign to us, subject to governmental
          approval, up to 10 MHz of licensed spectrum for an amount equal to the
          greater of either the original cost to Sprint PCS of the license plus
          any microwave clearing costs paid by Sprint PCS or 9% of our Entire
          Business Value; or

     o    choose not to terminate the management agreement and sue Sprint PCS
          for damages or submit the matter to arbitration.

See "Item 1. Business -- Markets" for a listing of our markets in which Sprint
PCS is currently the licensee for 20 MHz or more of the spectrum.

    If Sprint PCS has the right to terminate the management agreement because of
an event of termination caused by us, generally Sprint PCS may:

     o    require us, without further stockholder approval, to sell our
          operating assets to Sprint PCS for an amount equal to 72% of our
          Entire Business Value;

     o    require us to purchase, subject to governmental approval, the licensed
          spectrum in our territory for an amount equal to the greater of either
          the original cost to Sprint PCS of the license plus any microwave
          relocation costs paid by Sprint PCS or 10% of our Entire Business
          Value;

     o    take any action as Sprint PCS deems necessary to cure our breach of
          the management agreement, including assuming responsibility for, and
          operating, our portion of the Sprint PCS network; or

     o    not terminate the management agreement and sue us for damages or
          submit the matter to arbitration.

NON-RENEWAL

    If Sprint PCS gives us timely notice that it does not intend to renew the
management agreement, we may:

     o    require Sprint PCS to purchase all of our operating assets used in
          connection with our portion of the Sprint PCS network for an amount
          equal to 80% of our Entire Business Value; or

     o    in all areas in our territory where Sprint PCS is the licensee for 20
          MHz or more of the spectrum on the date we terminate the management
          agreement, require Sprint PCS to assign to us, subject to governmental
          approval, up to 10 MHz of licensed spectrum for an amount equal to the
          greater of either the original cost to Sprint PCS of the license plus
          any microwave relocation costs paid by Sprint PCS or 10% of our Entire
          Business Value.

                                       21
<PAGE>   23

    If we give Sprint PCS timely notice of non-renewal, or we both give notice
of non-renewal, or the management agreement expires with neither party giving a
written notice of non-renewal, or the management agreement can be terminated for
failure to comply with legal requirements or regulatory considerations, Sprint
PCS may:

     o    purchase all of our operating assets, without further stockholder
          approval, for an amount equal to 80% of our Entire Business Value; or

     o    require us to purchase, subject to governmental approval, the licensed
          spectrum in our territory for an amount equal to the greater of either
          the original cost to Sprint PCS of the license plus any microwave
          clearing costs paid by Sprint PCS or 10% of our Entire Business Value.

See "Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operation -- Risk Factors: Risks Related to our Relationship with
Sprint PCS -- Provisions of our affiliation agreements with Sprint PCS may
diminish our value and restrict the sale of our business" for a discussion of
possible effects of this part of the management agreement.

DETERMINATION OF ENTIRE BUSINESS VALUE

    If the Entire Business Value is to be determined, we and Sprint PCS will
each select one independent appraiser and the two appraisers will select a third
appraiser. The three appraisers will determine the Entire Business Value on a
going concern basis using the following guidelines:

     o    the Entire Business Value is based on the price a willing buyer would
          pay a willing seller for the entire on-going business;

     o    then-current customary means of valuing a wireless telecommunications
          business will be used;

     o    the business is conducted under the Sprint and Sprint PCS brands and
          our affiliation agreements with Sprint PCS;

     o    that we own the spectrum and frequencies presently owned by Sprint PCS
          and subject to our affiliation agreements with Sprint PCS; and

     o    the valuation will not include any value for businesses not directly
          related to the Sprint PCS products and services, and those businesses
          will not be included in the sale.

    The rights and remedies of Sprint PCS outlined in the management agreement
resulting from an event of termination of the management agreement have been
materially amended by the consent and agreement as discussed below.

INSURANCE

    We are required to obtain and maintain with financially reputable insurers
who are licensed to do business in all jurisdictions where any work is performed
under the management agreement and who are reasonably acceptable to Sprint PCS,
workers' compensation insurance, commercial general liability insurance,
business automobile insurance, umbrella excess liability insurance and "all
risk" property insurance.

INDEMNIFICATION

    We have agreed to indemnify Sprint PCS and its directors, employees and
agents and related parties of Sprint PCS and their directors, employees and
agents against any and all claims against any of the foregoing arising from our
violation of any law, a breach by us of any representation, warranty or covenant
contained in the management agreement or any other agreement between us and
Sprint PCS, our ownership of the operating assets or the actions or the failure
to act of anyone employed or hired by us in the performance of any work under
this agreement, except we will not indemnify Sprint PCS for any claims arising
solely from the negligence or willful misconduct of Sprint PCS. Sprint PCS has
agreed to indemnify us and our directors, employees and agents against all
claims against any of the foregoing arising from Sprint PCS's violation of any
law and from Sprint PCS's breach of any representation, warranty or covenant
contained in this agreement or any other agreement between Sprint PCS and us,
except Sprint PCS will not indemnify us for any claims arising solely from our
negligence or willful misconduct.

                                       22
<PAGE>   24

DISPUTE RESOLUTION

    If the parties cannot resolve any dispute between themselves and the
management agreement itself does not provide a remedy, then either party may
require that any dispute be resolved by a binding arbitration.

OUR AFFILIATION AGREEMENTS WITH SPRINT PCS: THE SERVICES AGREEMENT

    The services agreement outlines various back office services provided by
Sprint PCS and available to us for an adjustment to our 92% fee. Sprint PCS can
change the amount of adjustment for any or all of the services one time in any
twelve month period. We have the option to cancel a service upon notification of
a fee increase, and if we decide to cancel the service, then Sprint PCS, at our
option, must continue to provide that service for nine months at the original
price. Some of the available services include: billing, customer care,
activation, credit checks, handset logistics, home locator record, voice mail,
prepaid services, directory assistance, operator services, roaming fees, roaming
clearinghouse fees, interconnect fees and inter-territory fees. Sprint PCS
offers three packages of available services. Each package identifies which
services must be purchased from Sprint PCS and which may be purchased from a
vendor or provided in-house. Essentially, services such as billing, activation
and customer care must all be purchased from Sprint PCS or none may be purchased
from Sprint PCS. We have chosen to initially delegate the performance of these
services to Sprint PCS but may develop an independent capability with respect to
these services over time. Sprint PCS may contract with third parties to provide
expertise and services identical or similar to those to be made available or
provided to us. We have agreed not to use the services performed by Sprint PCS
in connection with any other business or outside our territory. We may
discontinue use of any service upon three months' prior written notice, while
Sprint PCS must give nine months notice if it will no longer offer any service.

    We have agreed with Sprint PCS to indemnify each other as well as officers,
directors, employees and other related parties and their officers, directors and
employees for violations of law or the services agreement except for any
liabilities resulting from the negligence or willful misconduct of the person
seeking to be indemnified or its representatives. The services agreement also
provides that no party to the agreement will be liable to the other party for
special, indirect, incidental, exemplary, consequential or punitive damages, or
loss of profits arising from the relationship of the parties or the conduct of
business under, or breach of, the services agreement except as may otherwise be
required by the indemnification provisions. The services agreement automatically
terminates upon termination of the management agreement, and neither party may
terminate the services agreement for any reason other than the termination of
the management agreement.

OUR AFFILIATION AGREEMENTS WITH SPRINT PCS: THE TRADEMARK AND SERVICE MARK
LICENSE AGREEMENTS

    We have non-transferable licenses to use, at no additional cost to us, the
Sprint and Sprint PCS brand names and "diamond" symbol, and several other U.S.
trademarks and service marks such as "The Clear Alternative to Cellular" and
"Clear Across the Nation" on Sprint PCS products and services. We believe that
the Sprint and Sprint PCS brand names and symbols enjoy a high degree of
awareness, providing us an immediate benefit in the market place. Our use of the
licensed marks is subject to our adherence to quality standards determined by
Sprint and Sprint PCS and use of the licensed marks in a manner which would not
reflect adversely on the image of quality symbolized by the licensed marks. We
have agreed to promptly notify Sprint and Sprint PCS of any infringement of any
of the licensed marks within our territory of which we become aware and to
provide assistance to Sprint and Sprint PCS in connection with Sprint's and
Sprint PCS's enforcement of their respective rights. We have agreed with Sprint
and Sprint PCS to indemnify each other for losses incurred in connection with a
material breach of the trademark license agreements. In addition, we have agreed
to indemnify Sprint and Sprint PCS from any loss suffered by reason of our use
of the licensed marks or marketing, promotion, advertisement, distribution,
lease or sale of any Sprint or Sprint PCS products and services other than
losses arising solely out of our use of the licensed marks in compliance with
certain guidelines.

Sprint and Sprint PCS can terminate the trademark and service mark license
agreements if we file for bankruptcy, materially breach the agreement or our
management agreement is terminated. We can terminate the trademark and service
mark license agreements upon Sprint's or Sprint PCS's abandonment of the
licensed marks or if Sprint or Sprint PCS files for bankruptcy or the management
agreement is terminated. However, Sprint and Sprint PCS can assign their
interests in the licensed marks to a third party if that third party agrees to
be bound by the terms of the trademark and service mark license agreements.

REGULATION OF THE WIRELESS TELECOMMUNICATIONS INDUSTRY

    The Federal Communications Commission can have a substantial impact upon
entities that manage wireless personal communications services systems and/or
provide wireless personal communications services because the Federal
Communications Commission regulates the licensing, construction, operation,
acquisition and interconnection arrangements of wireless telecommunications
systems in the United States.

    The Federal Communications Commission has promulgated, and is in the process
of promulgating, a series of rules, regulations and policies to, among other
things:

     o    grant or deny licenses for wireless personal communications services
          frequencies;

     o    grant or deny wireless personal communications services license
          renewals;

     o    rule on assignments and/or transfers of control of
          wireless personal communications services licenses;

     o    govern the interconnection of wireless personal communications
          services networks with other wireless and wireline service providers;

     o    establish access and universal service funding provisions;

     o    impose fines and forfeitures for violations of any of the Federal
          Communications Commission's rules; and

     o    regulate the technical standards of wireless personal communications
          services networks.

    The Federal Communications Commission currently prohibits a single entity
from having a combined attributable interest, of 20% or greater interest in any
license, in broadband wireless personal communications services, cellular and
specialized mobile radio, commonly referred to as SMR, licenses totaling more
than 45 MHz in any geographic area. The 45 MHz cap is raised to 55 MHz for
cellular spectrum in rural areas. The 20% cap is raised to 40% where the
relevant single entity is a small business or a rural telephone company. The
geographic area at issue is the PCS licensed service area, where there can be
significant overlap involving 10% or more of the population in the geographic
area.

TRANSFERS AND ASSIGNMENTS OF WIRELESS PERSONAL COMMUNICATIONS SERVICES LICENSES

    The Federal Communications Commission must give prior approval to the
assignment of, or transfers involving, substantial changes in ownership or
control of a wireless personal communications services license. This means that
our stockholders and we will receive advance notice of any and all transactions
involved in transferring control of Sprint PCS or the assignment of some or all
of the wireless personal communications services licenses held by Sprint PCS.
The Federal Communications Commission proceedings afford our stockholders and us
an opportunity to evaluate proposed transactions well in advance of closing, and
to take actions necessary to protect our interests. Non-controlling interests in
an entity that holds a wireless personal communications services license or
operates wireless personal communications services networks generally may be
bought or sold without prior Federal Communications Commission approval. In
addition, a recent Federal Communications Commission order requires only post-
consummation notification of pro forma assignments or transfers of control.

CONDITIONS OF WIRELESS PERSONAL COMMUNICATIONS SERVICES LICENSES

    All wireless personal communications services licenses are granted for ten
year terms conditioned upon timely compliance with the Federal Communications
Commission's build-out requirements. Pursuant to the Federal Communications
Commission's build-out requirements, all 30 MHz broadband wireless personal
communications services licensees must construct facilities that offer coverage
to one-third of the population within five years and to two-thirds of the
population within ten years, and all 10 MHz broadband wireless personal
communications services licensees must construct facilities that offer coverage
to at least one-quarter of the population within five years or make a showing of
"substantial service" within that five year period. If the build-out
requirements are not met, wireless personal communications services licenses
could be forfeited. The Federal Communications Commission also requires
licensees to maintain control over their licenses. Our affiliation agreements
with Sprint PCS reflect a management agreement that the parties believe meets
the Federal Communications Commission requirements for licensee control of
licensed spectrum. If the Federal Communications Commission were to determine
that our affiliation agreements with Sprint PCS need to be modified to increase
the level of licensee control, we have agreed




                                       24
<PAGE>   26

with Sprint PCS to use our best efforts to modify the agreements necessary to
cause the agreements to comply with applicable law and to preserve to the extent
possible the economic arrangements set forth in the agreements. If the
agreements cannot be modified, the agreements may be terminated pursuant to
their terms. The Federal Communications Commission could also impose monetary
penalties on Sprint PCS, and possibly revoke one or more of the Sprint PCS
licenses.

WIRELESS PERSONAL COMMUNICATIONS SERVICES LICENSE RENEWAL

    Wireless personal communications services licensees can renew their licenses
for additional ten year terms. Wireless personal communications services renewal
applications are not subject to auctions. However, under the Federal
Communications Commission's rules, third parties may oppose renewal applications
and/or file competing applications. If one or more competing applications are
filed, a renewal application will be subject to a comparative renewal hearing.
The Federal Communications Commission's rules afford wireless personal
communications services renewal applicants involved in comparative renewal
hearings with a "renewal expectancy." The renewal expectancy is the most
important comparative factor in a comparative renewal hearing and is applicable
if the wireless personal communications services renewal applicant has:

     o    provided "substantial service" during its license term; and

     o    substantially complied with all applicable laws and Federal
          Communications Commission rules and policies.

    The Federal Communications Commission's rules define "substantial service"
in this context as service that is sound, favorable and substantially above the
level of mediocre service that might minimally warrant renewal. The Federal
Communications Commission's renewal expectancy and procedures make it very
likely that Sprint PCS will retain the wireless personal communications services
licenses managed by us for the foreseeable future.

INTERCONNECTION

    The Federal Communications Commission has the authority to order
interconnection between commercial mobile radio services, commonly referred to
as CMRS, providers and any other common carrier. The Federal Communications
Commission has ordered local exchange carriers to provide reciprocal
compensation to commercial mobile radio service providers for the termination of
traffic. Using these new rules, we will assist Sprint PCS in the negotiation of
interconnection agreements for the Sprint PCS network in our market area with
all of the major regional Bell operating companies, GTE and several smaller
independent local exchange carriers. Interconnection agreements are negotiated
on a state-wide basis. If an agreement cannot be reached, parties to
interconnection negotiations can submit outstanding disputes to state
authorities for arbitration. Negotiated interconnection agreements are subject
to state approval. The Federal Communications Commission rules and rulings, as
well as the state arbitration proceedings, will directly impact the nature and
cost of the facilities necessary for interconnection of the Sprint PCS systems
with local, national and international telecommunications networks. They will
also determine the nature and amount of revenues we and Sprint PCS can receive
for terminating calls originating on the networks of local exchange and other
telecommunications carriers.

OTHER FEDERAL COMMUNICATIONS COMMISSION REQUIREMENTS

    In June 1996, the Federal Communications Commission adopted rules that
prohibit broadband wireless personal communications services providers from
unreasonably restricting or disallowing resale of their services or unreasonably
discriminating against resellers. Resale obligations will automatically expire
on November 24, 2002. The Federal Communications Commission is also considering
whether wireless providers should be required to offer unbundled communications
capacity to resellers who intend to operate their own switching facilities.
These existing resale requirements and their expiration may somewhat affect the
number of resellers competing with Sprint PCS and its managers and affiliates in
various markets. However, to date, wireless resellers have not significantly
impacted wireless service providers. Any losses in retail customers have been
offset, in major part, by increases in wireless customers, traffic and wholesale
revenues.

    The Federal Communications Commission also adopted rules in June 1996 that
require local exchange and most commercial mobile radio services providers, to
program their networks to allow customers to change service providers without
changing telephone numbers, which is referred to as service provider number
portability. The Federal Communications Commission requires most commercial
mobile radio service providers to implement



                                       25
<PAGE>   27

wireless service provider number portability where requested in the 100 largest
metropolitan areas in the United States by November 24, 2002. Most commercial
mobile radio services providers are required to implement nationwide roaming by
November 24, 2002 as well. The Federal Communications Commission currently
requires most commercial mobile radio services providers to be able to deliver
calls from their networks to ported numbers anywhere in the country, and to
contribute to the Local Number Portability Fund. Implementation of wireless
service provider number portability will require wireless personal
communications services providers like us and Sprint PCS to purchase more
expensive switches and switch upgrades. However, it will also enable existing
cellular customers to change to wireless personal communications services
without losing their existing wireless telephone numbers, which should make it
easier for wireless personal communications services providers to market their
services to existing cellular users.

    The Federal Communications Commission has adopted rules permitting broadband
wireless personal communications services and other commercial mobile radio
services providers to provide wireless local loop and other fixed services that
would directly compete with the wireline services of local exchange carriers.
This creates new markets and revenue opportunities for Sprint PCS and its
managers and affiliates and other wireless providers, and may do so increasingly
in future years. In June 1996, the Federal Communications Commission adopted
rules requiring broadband wireless personal communications services and other
commercial mobile radio services providers to implement enhanced emergency 911
capabilities within 18 months after the effective date of the Federal
Communications Commission's rules. In December 1997, the Federal Communications
Commission revised these rules to extend the compliance deadline for phase I
until October 1, 1998 and for phase II until October 1, 2001 for digital
commercial mobile radio services providers to ensure access for customers using
devices for the hearing-impaired. The Federal Communications Commission recently
extended the phase I compliance deadline to January 1, 1999. Further waivers of
the enhanced emergency 911 capability requirements may be obtained by individual
service providers by filing a waiver request. The Federal Communications
Commission's waivers and extensions are enabling us, Sprint PCS and other
commercial mobile radio services industry members to delay emergency 911
implementation until the required equipment becomes more functional and less
expensive. However, at a more reasonable future cost, emergency 911 services may
afford wireless carriers substantial and attractive new service and marketing
opportunities.

    On June 10, 1999, the Federal Communications Commission initiated a
regulatory proceeding seeking comment from the public on a number of issues
related to competitive access to multiple-tenant buildings, including the
following:

     o    the Federal Communications Commission's tentative conclusion that the
          Communications Act of 1934, as amended, requires utilities to permit
          telecommunications service providers access to rooftop and other
          rights-of-way in multiple tenant buildings under just, reasonable and
          nondiscriminatory rates, terms and conditions; and

     o    whether building owners that make access available to a
          telecommunications service providers should be required to make access
          available to all other telecommunications service providers on a
          nondiscriminatory basis, and whether the Federal Communications
          Commission has the authority to impose such a requirement.

    This proceeding could affect the availability and pricing of sites for our
antennae and those of our competitors.

COMMUNICATIONS ASSISTANCE FOR LAW ENFORCEMENT ACT

    The Communications Assistance for Law Enforcement Act, or CALEA, enacted in
1994 requires wireless personal communications services and other
telecommunications service providers to meet capability and capacity
requirements needed by federal, state and local law enforcement to preserve
their electronic surveillance capabilities. Wireless personal communications
services providers must comply with the current industry CALEA capability
standard, known as J-STD-025, by June 30, 2000, and with recently adopted
additions by September 30, 2001. Wireless personal communications services
providers must comply with the CALEA capacity requirements by March 12, 2001. At
present, most wireless personal communications services providers are ineligible
for federal reimbursement for the software and hardware upgrades necessary to
comply with the CALEA capability and capacity requirements, but several bills
pending in Congress may expand reimbursement rights if they are enacted. In
addition, the Federal Bureau of Investigation has been discussing with the
industry options for reducing or waiving CALEA compliance requirements in
geographic areas with minimal or nonexistent electronic surveillance needs.



                                       26
<PAGE>   28

    In addition, the Federal Communications Commission is considering petitions
from numerous parties to establish and implement technical compliance standards
pursuant to CALEA requirements. In sum, CALEA capability and capacity
requirements are likely to impose some additional switching and network costs
upon Sprint PCS and its managers and affiliates and other wireless entities.
However, it is possible that some of these costs will be reduced or delayed if
current law enforcement or legislative initiatives are adopted and implemented
during 2000 or thereafter.

OTHER FEDERAL REGULATIONS

    Sprint PCS and its managers and affiliates must bear the expense of
compliance with Federal Communications Commission and Federal Aviation
Administration regulations regarding the siting, lighting and construction of
transmitter towers and antennas. In addition, Federal Communications Commission
environmental regulations may cause some of our base station locations to become
subject to the additional expense of regulation under the National Environmental
Policy Act. The Federal Communications Commission is required to implement this
Act by requiring service providers to meet land use and radio frequency
standards.

REVIEW OF UNIVERSAL SERVICE REQUIREMENTS

    The Federal Communications Commission and the states are required to
establish "universal service" programs to ensure that affordable, quality
telecommunications services are available to all Americans. Sprint PCS is
required to contribute to the federal universal service program as well as
existing state programs. The Federal Communications Commission has determined
that the Sprint PCS's "contribution" to the federal universal service program is
a variable percentage of "end-user telecommunications revenues." Although many
states are likely to adopt a similar assessment methodology, the states are free
to calculate telecommunications service provider contributions in any manner
they choose as long as the process is not inconsistent with the Federal
Communications Commission's rules. At the present time it is not possible to
predict the extent of the Sprint PCS total federal and state universal service
assessments or its ability to recover from the universal service fund. However,
some wireless entities are seeking state commission designation as "eligible
telecommunications carriers," enabling them to receive federal and state
universal service support, and are preparing to compete aggressively with
wireline telephone companies for universal service revenue. Because we manage
substantial rural areas for Sprint PCS, we are likely to receive revenues in the
future from federal and state universal service support funds that are much
greater than the reductions in our revenues due to universal service
contributions paid by Sprint PCS.

PARTITIONING; DISAGGREGATION

    The Federal Communications Commission has modified its rules to allow
broadband wireless personal communications services licensees to partition their
market areas and/or to disaggregate their assigned spectrum and to transfer
partial market areas or spectrum assignments to eligible third parties. These
rules may enable us to purchase wireless personal communications services
spectrum from Sprint PCS and other wireless personal communications services
licensees as a supplement or alternative to the existing management
arrangements.

WIRELESS FACILITIES SITING

    States and localities are not permitted to regulate the placement of
wireless facilities so as to "prohibit" the provision of wireless services or to
"discriminate" among providers of those services. In addition, so long as a
wireless system complies with the Federal Communications Commission's rules,
states and localities are prohibited from using radio frequency health effects
as a basis to regulate the placement, construction or operation of wireless
facilities. These rules are designed to make it possible for Sprint PCS and its
managers and affiliates and other wireless entities to acquire necessary tower
sites in the face of local zoning opposition and delays. The Federal
Communications Commission is considering numerous requests for preemption of
local actions affecting wireless facilities siting.

EQUAL ACCESS

    Wireless providers are not required to provide equal access to common
service providers for toll services. This enables us and Sprint PCS to generate
additional revenues by reselling the toll services of Sprint PCS and other
interexchange carriers from whom we can obtain favorable volume discounts.
However, the FCC is authorized to require unblocked access to toll service
providers subject to certain conditions.

STATE REGULATION OF WIRELESS SERVICE

    Section 332 of the Communications Act preempts states from regulating the
rates and entry of commercial mobile radio service providers. Section 332 does
not prohibit a state from regulating the other terms and conditions of
commercial mobile services, including consumer billing information and
practices, billing disputes and other consumer protection matters. However,
states may petition the Federal Communications Commission to regulate those
providers and the Federal Communications Commission may grant that petition if
the state demonstrates that:

     o    market conditions fail to protect subscribers from unjust and
          unreasonable rates or rates that are unjustly or unreasonably
          discriminatory; or

     o    when commercial mobile radio service is a replacement for landline
          telephone service within the state.

To date, the Federal Communications Commission has granted no such petition. To
the extent Sprint PCS and its managers and affiliates provide fixed wireless
service, we may be subject to additional state regulation. These standards and
rulings have prevented states from delaying the entry of wireless personal
communications services and other wireless carriers into their jurisdictions via
certification and similar requirements, and from delaying or inhibiting
aggressive or flexible wireless price competition after entry.

    ITEM 2. PROPERTIES.

    Our headquarters are located in Lubbock, Texas and we lease space in a
number of locations, primarily for our Sprint PCS stores, base stations and
switching centers. As of December 31, 1999, we had 15 retail stores and four
switching centers. As of December 31, 1999, we leased space on 248 towers and
owned one tower. We collocate with other wireless service providers on
approximately 37% of our towers. We believe that our facilities are adequate for
our current operations and that additional leased space can be obtained if
needed on commercially reasonable terms.

    ITEM 3. LEGAL PROCEEDINGS.

    We and our subsidiaries are not parties to any pending legal proceedings
that we believe would, if adversely determined, individually or in the
aggregate, have a material adverse effect on our, or our subsidiaries',
financial condition or results of operations.

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

    In connection with our initial public offering, on December 9, 1999, we
received appropriate approval of the members of Alamosa PCS, LLC, our former
operating entity, at a special meeting of the members, of the following actions:

     o    to restructure Alamosa PCS, LLC as described in "Item 1. Business--Our
          Background";

     o    to have a high-yield debt offering; and

     o    to enter into employment agreements with David E. Sharbutt, Kendall W.
          Cowan and Jerry W. Brantley.

    ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
            MATTERS.

    Our common stock has traded on the Nasdaq National Market under the symbol
"APCS" since February 3, 2000. Prior to that date, there was no public market
for our common stock. No quoted market prices for our common stock are available
for the years ended December 31, 1999 and 1998.

    The following table sets forth, for the periods indicated, the range of high
and low closing sales price of our common stock as reported on the Nasdaq
National Market.

</TABLE>

    On March 23, 2000, the last reported sales price of our common stock as
reported on the Nasdaq National Market was $36.50 per share. On March
23, 2000, there were 74 holders of record of our common stock.

    We have never declared or paid any cash dividends on our common stock or
other securities. We do not expect to pay cash dividends on our capital stock in
the foreseeable future. We currently intend to retain our future earnings, if
any, to fund the development and growth of our business. Future dividends, if
any, will be determined by our board of directors and will depend upon our
results of operations, financial condition and capital expenditure plans, as
well as other factors that our board of directors considers relevant. The Nortel
financing does not restrict our ability to pay dividends. However, the Nortel
financing prohibits our subsidiaries from paying dividends or making
distributions, except for stock dividends and for distributions to fund the
payment of the interest on our senior discount notes, without Nortel's consent.
Accordingly, the Nortel financing makes it very difficult for us to pay any cash
dividends to our stockholders.

RECENT SALES OF UNREGISTERED SECURITIES

    We were formed on October 19, 1999. At that time we had no assets and had
issued no capital stock. Immediately prior to the closing of our initial public
offering, we were reorganized as described in "Item 1. Business -- Our
Background." In connection with our reorganization, we merged with Alamosa PCS
Holdings, Inc., a Texas corporation ("Texas Holdings"). To effectuate the
merger, we issued 100 shares of our common stock to Texas Holdings. We then
merged with Texas Holdings, and we were the surviving corporation. In the
merger, we issued unregistered shares of our common stock to the stockholders of
Texas Holdings.

    We also granted stock options to directors, officers, employees and
consultants before the closing of our initial public offering, pursuant to the
terms of our 1999 Long-Term Incentive Plan. These are our only unregistered
issuances of securities before or after our initial public offering.

    Texas Holdings is the successor to our former operating entity, Alamosa PCS,
LLC, by virtue of a conversion of the LLC to a corporation.

    The persons who received our common stock in connection with our
reorganization, their owners, the consideration we received for such common
stock and the number of shares of common stock to be received are set forth in
the tables below.

(1)  All percentages of membership interests, except options, are calculated on
     a non-fully diluted basis. Percentages for options to purchase membership
     interests are calculated on a fully diluted basis.

(2)  Includes or consists of shares held in a 401(k) plan.

(3)  Represents options to acquire securities, not issued securities.

(4)  The consideration for these stock options is an option to purchase a
     membership interest in Alamosa PCS, LLC as well as his employment with us.

    None of the foregoing transactions involved any public offering, and
issuances of securities in connection with such transactions were made pursuant
to valid exemptions under the Securities Act. The following were the exemptions
relied on for each issuance of securities pursuant to our reorganization.

    First, our issuance of 100 shares to Texas Holdings was exempt under Section
4(2) of the Securities Act. This issuance of 100 shares was a transaction
involving one offeree, involving no general solicitation.

    Second, our issuance of 48,500,008 shares to the twenty-nine stockholders of
Texas Holdings, pursuant to the merger of Texas Holdings with and into us, was
exempt under Section 4(2). The merger took place through direct communication
with the offerees, with no general solicitation or advertising. Since we are a
subsidiary of Texas Holdings, these offerees had a pre-existing and substantial
relationship with us.

    The options to purchase a total of 6,184,500 shares were granted pursuant to
a written compensatory benefit plan or written compensation contract to the
directors, employees and consultants, and were exempt pursuant to Rule 701.
48,500,008 shares were outstanding prior to the grant of these options. The
6,184,500 shares is under the maximum of 15% of 48,500,008, or 7,275,001
provided in Rule 701(d)(2).

USE OF PROCEEDS FROM SALES OF REGISTERED SECURITIES

    We commenced our initial public offering on February 3, 2000 pursuant to a
Registration Statement on Form S-1, file no. 333-89995, that was declared
effective on February 2, 2000. On February 8, 2000, we consummated the offering.
The managing underwriters of the public offering were Salomon Smith Barney Inc.,
Lehman Brothers Inc., Credit Suisse First Boston Corporation and Deutsche Bank
Securities Inc. In the offering, we registered and sold an aggregate of
12,321,100 shares of our common stock, including 1,607,100 shares of common
stock pursuant to the exercise of the underwriters' over-allotment option. The
aggregate price of the shares offered and sold was approximately $208.6 million.
Our net proceeds, after accounting for approximately $13.3 million in
underwriting discounts and commissions and approximately $1.0 million in other
expenses, were approximately $194.3 million.

    We commenced our sale of the senior discount notes on February 3, 2000
pursuant to a Registration Statement on Form S-1, file no. 333-93499, that was
declared effective on February 2, 2000. On February 8, 2000, we consummated the
offering. The managing underwriters of the sale of the senior discount notes
were Salomon Smith Barney Inc., Credit Suisse First Boston Corporation and
Lehman Brothers Inc. In the offering, we registered and sold $350 million
aggregate principal amount at maturity of the senior discount notes at an
aggregate price to the public of $187.1 million. Our net proceeds from the sale
of the senior discount notes, after accounting for approximately $6.1 million in
underwriting discounts and commissions and other offering expenses, were
approximately $181 million.

    As of March 23, 2000, approximately $90 million of the net proceeds from the
sales of the registered securities had been used, including $75 million of
indebtedness outstanding under the Nortel credit facility, $4 million of
origination fees in connection with the Nortel credit facility and $7 million
for capital expenditures and working capital purposes. The balance of the net
proceeds were invested in short-term interest-bearing investment grade
securities.



                                       32
<PAGE>   34

    We are using the net proceeds from our initial public offering to fund the
following cash expenditures through 2002:

     o    capital expenditures of approximately $216 million, representing the
          build-out of markets in Wisconsin, Arizona and Colorado, as well as
          the further expansion of coverage in existing markets in Texas and New
          Mexico;

     o    net operating losses and working capital requirements of approximately
          $11 million;

     o    interest expense, principal payments and loan origination fees of
          approximately $45 million; and

     o    general corporate purposes.

    We used a portion of the net proceeds from the sale of the senior discount
notes to prepay $75 million of indebtedness outstanding under the Nortel credit
facility. We are using the remaining proceeds of the debt offering to:

     o    accelerate coverage within our existing territory;

     o    build-out additional areas within our existing territory;

     o    expand our existing territory;

     o    pursue additional telecommunications business opportunities or acquire
          other telecommunications businesses or assets; and

     o    cover general corporate purposes.

    However, if we do not use the remaining proceeds from the sale of the senior
discount notes for the above purposes, we may decide to:

     o    prepay additional debt outstanding under the Nortel credit facility;
          or

     o    avoid drawing additional amounts under the Nortel credit facility.

    We retain broad discretion in the allocation of the net proceeds of both of
our offerings. This discussion represents our best estimate of the allocation of
the net proceeds based upon our current plans. Actual expenditures may vary
substantially from these plans and we may find it necessary or advisable to
reallocate the net proceeds within the above-described categories or to use
portions for other purposes. The timing and the coverage of our build-out plan
may change due to various reasons, including shifts in populations or network
focus, changes or advances in technology, acquisition of other markets,
businesses, products or technologies and factors causing a delay in the
build-out of some markets. Any changes in the timing or build-out plan may cause
changes in our use of proceeds. Additionally, we may use a portion of the net
proceeds to acquire or invest in businesses, products or technologies that are
complementary to our business. We currently do not have any commitments or
agreements for any acquisitions or investments of this kind.

    Pending these uses, we expect to invest the net proceeds from our two
offerings in short-term investment grade securities, which will earn interest.

    None of the net offering proceeds were, directly or indirectly, paid by us
to our directors or officers or their associates, persons owning 10% or more of
any class of our securities, or our affiliates. Portions of the proceeds of the
offering will be paid to CHR Solutions in connection with the build out of our
network. See "Item 13. Certain Relationships and Related Transactions -
Agreements with CHR Solutions."

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

    You should read the following discussion and analysis when you read the
consolidated financial statements and the related notes included in this annual
report on Form 10-K. The discussion contains forward-looking statements that
involve risks and uncertainties. Our actual results could differ materially from
the results anticipated in these forward-looking statements as a result of
factors including, but not limited to, those under "Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operation -- Risk
Factors" and "This Annual Report Contains Forward-Looking Statements."

OVERVIEW

    We are a development stage company with very limited operations, very
limited revenues, significant losses, substantial future capital requirements
and an expectation of continued losses.

    Since our inception, we have incurred substantial costs to negotiate our
contracts with Sprint PCS and our debt financing from Nortel, to engineer our
wireless system, to develop our business infrastructure and distribution
channels and to begin the build-out of our portion of the Sprint PCS network.
Prior to the opening of Laredo on June 22, 1999, we did not have any markets in
operation. As of December 31, 1999, our accumulated deficit was $33.8 million.
Through December 31, 1999, we incurred $87.8 million of capital expenditures and
construction in progress related to the build-out of our portion of the Sprint
PCS network. While we anticipate operating losses to continue, we expect revenue
to increase substantially as the base of Sprint PCS subscribers located in our
territory increases.

    On July 17, 1998, we entered into our affiliation agreements with Sprint
PCS. We have recently amended our affiliation agreements with Sprint PCS to
expand our territory so that it will include approximately 8.4 million
residents.

    As a Sprint PCS affiliate, we have the exclusive right to provide digital
wireless personal communication services under the Sprint and Sprint PCS brand
names in our territory. We are responsible for building, owning and managing the
portion of the Sprint PCS network located in our territory. We market wireless
products and services in our territory under the Sprint and Sprint PCS brand
names. We offer national plans designed by Sprint PCS and intend to offer
specialized local plans tailored to our market demographics. Our portion of the
Sprint PCS network is designed to offer a seamless connection with Sprint PCS's
100% digital wireless network. We market wireless products and services through
a number of distribution outlets located in our territory, including our own
Sprint PCS stores, major national distributors and third party local
representatives.

    We launched Sprint PCS service in our first market, Laredo, in June 1999,
and have since commenced service in ten additional markets: Albuquerque, Santa
Fe, El Paso, Las Cruces, Lubbock, Amarillo, Midland, Odessa, Abilene and San
Angelo. Our systems cover approximately 2.7 million residents out of
approximately 3.9 million total residents in those markets. The number of
residents covered by our systems does not represent the number of Sprint PCS
subscribers that we expect to be based in our territory. As of December 31,
1999, 31,876 Sprint PCS subscribers were based in our territory.

    We recognize 100% of revenues from Sprint PCS subscribers based in our
territory, proceeds from the sales of handsets and accessories and fees from
Sprint PCS and other wireless service providers when their customers roam onto
our portion of the Sprint PCS network. Sprint PCS handles our billing and
collections and retains 8% of all collected revenue from Sprint PCS subscribers
based in our territory and fees from wireless service providers other than
Sprint PCS when their subscribers roam onto our portion of the Sprint PCS
network. We report the amount retained by Sprint PCS as an operating expense.

    As part of our affiliation agreements with Sprint PCS, we have the option of
contracting with Sprint PCS to provide back office services such as customer
activation, handset logistics, billing, customer service and network monitoring
services. We have elected to delegate the performance of these services to
Sprint PCS to take advantage of Sprint PCS's economies of scale, to accelerate
our build-out and market launches and to lower our initial capital requirements.
The cost for these services is primarily calculated on a per subscriber and per
transaction basis and is recorded as an operating expense.

REGULATORY DEVELOPMENTS

    See "Item 1. Business -- Regulation of the Wireless Telecommunications
Industry" for a discussion of regulatory developments that could have a future
impact on us.

SEASONALITY

    Our business is subject to seasonality because the wireless industry is
heavily dependent on fourth quarter results. Among other things, the industry
relies on significantly higher customer additions and handset sales in the
fourth quarter as compared to the other three fiscal quarters. A number of
factors contribute to this trend, including:

     o    the increasing use of retail distribution, which is dependent upon the
          year-end holiday shopping season;

     o    the timing of new product and service announcements and introductions;

     o    competitive pricing pressures; and

     o    aggressive marketing and promotions.

RESULTS OF OPERATIONS

FOR THE PERIOD JULY 16, 1998 (INCEPTION) THROUGH DECEMBER 31, 1998

    Revenues, Direct Costs and Net Loss. From inception through December 31,
1998, our operating activities were directed towards the development of our
business. During July 1998, we signed our affiliation agreements with Sprint PCS
to operate as the exclusive affiliate of Sprint PCS in our territory. Our
operating activities were focused on executing our build-out plan and developing
our network infrastructure. As our first market did not launch until June 1999,
the 1998 period reflects no service revenues, product sales or related costs
associated with services or products. Our net loss for the period was $923,822,
which was principally comprised of general and administrative expenses.

    General and Administrative Expenses. General and administrative expenses for
the period in the amount of $956,331 were comprised primarily of legal and other
professional services of $704,381 related to the start up of our business and
the development of our systems. In addition, we incurred $166,850 of human
resource costs related to preparation for the 1999 launch of our network.
Virtually all general and administrative expenses during this period related to
the start-up of the business and were expensed according to American Institute
of Certified Public Accountants Statement of Position 98-5, "Reporting on the
Costs of Start-up Activities."

YEAR ENDED DECEMBER 31, 1999

    Net Loss. Our net loss for the year ended December 31, 1999 was $32,835,859
and was comprised primarily of the continued incurrence of start-up expenses
relative to the preparation of our initial commercial market launch in June 1999
and 10 other market launches during the period.

    Service Revenues. Service revenues during the period in the amount of
$6,533,623 are comprised of subscriber revenue, Sprint PCS roaming revenue,
non-Sprint PCS roaming revenue and long distance revenue, all of which initially
began accruing to us at or near our first initial commercial launch in June
1999. Subscriber revenue consists of payments received from Sprint PCS
subscribers based in our territory for monthly Sprint PCS service in our
territory under a variety of service plans. These plans generally reflect the
terms of national plans offered by Sprint PCS and are issued on a month-to-month
basis. We receive Sprint PCS roaming revenue at a per minute rate from Sprint
PCS or another Sprint PCS affiliate when Sprint PCS subscribers based outside of
our territory use our portion of the Sprint PCS network.

    Pursuant to our affiliation agreements with Sprint PCS, Sprint PCS can
change this per minute rate. Non-Sprint PCS roaming revenue primarily consists
of fees collected from Sprint PCS customers based in our territory when they
roam on non-Sprint PCS networks. These fees are based on rates specified in the
customers' contracts. However, it is possible that in some cases these fees may
be less than the amount we must pay to other wireless service providers that
provide service to Sprint PCS customers based in our territory. Non-Sprint PCS
roaming revenue also includes payments from wireless service providers, other
than Sprint PCS, when those providers' customers roam on our



                                       36
<PAGE>   38

portion of the Sprint PCS network. Our average monthly revenue per user for
Sprint PCS customers in our territory, including long distance and roaming
revenue, was approximately $96.00 for the period from June 26, 1999 to December
31, 1999.

    Product Sales. 100% of the revenue from the sale of handsets and accessories
are recorded, net of an allowance for returns, as product sales. The amount
recorded during this period totaled $2,450,090. Sprint PCS's handset return
policy allows customers to return their handsets for a full refund within 30
days of purchase. When handsets are returned to us, we may be able to reissue
the handsets to customers at little additional cost to us. However, when
handsets are returned to Sprint PCS for refurbishing, we receive a credit from
Sprint PCS, which is less than the amount we originally paid for the handset.

    Cost of Service and Operations. Expenses totaling $7,440,476 during this
period related to providing wireless services to customers and are included in
cost of services. Among these costs are the cost of operations, fees related to
data transfer via T-1 and other transport lines, inter-connection fees, Sprint
PCS roaming fees, non-Sprint PCS roaming fees and other expenses related to
operations. We pay Sprint PCS roaming fees when Sprint PCS subscribers based in
our territory use the Sprint PCS network outside of our territory. Pursuant to
our affiliation agreements with Sprint PCS, Sprint PCS can change this per
minute rate. We pay non-Sprint PCS roaming fees to other wireless service
providers when Sprint PCS customers based in our territory use their network.

    Cost of Product Sales. The cost of equipment sold totaling $2,403,306 during
this period includes the cost of accessories and the cost of handsets up to the
retail sales price. We expect the cost of handsets to exceed the retail sales
price because we subsidize the price of handsets for competitive reasons. We
recognize any excess of the cost of handsets over the retail sales price as an
advertising expense. For the year ended December 31, 1999, the handset subsidy
totaled $5,023,430 and there was no expense related to handset subsidy in 1998.

    Selling and Marketing. Selling and marketing expenses totaled $14,346,478
during the period. Sales and marketing expenses include advertising expenses,
promotion costs, sales commissions and expenses related to our distribution
channels. Advertising expenses include any excess of the cost of a handset over
the retail price.

    General and Administrative Expenses. General and administrative expenses
include corporate costs and expenses other than those related to Cost of
Operations and Selling and Marketing. We have incurred significant general and
administrative expenses related to the development of our system. Virtually all
of these expenses are related to the start-up of the business and were expensed
according to American Institute of Certified Public Accountants Statement of
Position 98-5, "Reporting on the Costs of Start-up Activities."

    Non-cash Compensation Expense. Non-cash compensation expense totaled
$8,199,511 for the period. This expense was determined using the provisions of
Accounting Principles Board Opinion No. 25 "Accounting for Stock Issued to
Employees" and was based on the estimated intrinsic value of the options at
December 31, 1999. The estimated intrinsic value represents the excess of the
estimated fair value over the exercise price of the option.

    Related Party Expenses. Related party expenses totaled $1,726,198 for the
period and was primarily comprised of information technology and other
professional consulting expenses incurred in connection with a contract between
us and a telecommunications engineering and consulting firm. Several key
officers and owners of this consulting firm have an equity ownership interest in
us.

    Depreciation and Amortization. Depreciation and amortization during the
period totaled $3,056,923. Depreciation is calculated using the straight line
method over the useful life of the asset. We begin to depreciate the assets for
each market only after we open that market.

    Interest and Other Income. Interest and other income totaling $477,390
during this period generally have been generated from the investment of equity
and loan proceeds held in liquid accounts waiting to be deployed.

    Interest Expense. Interest expense totaled $2,641,293 during this period and
primarily related to the Nortel financing. Interest on the Nortel financing may
be paid with loans obtained under the Tranche C Commitment of the Nortel
financing until, in most circumstances, February 2002. See "-- Description of
Our Indebtedness: The Nortel Credit Facility." Gains or losses on hedging
transactions related to interest rates will be included in interest expense.

                                       37
<PAGE>   39
INCOME TAXES

    Our financial statements did not report any benefit for federal and state
income taxes since we had elected to be taxed as a partnership prior to our
reorganization. For the periods presented, the members of the limited liability
company recorded our tax losses on their own income tax returns. Subsequent to
the reorganization, we will account for income taxes in accordance with
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes." Had we applied the provisions of SFAS No. 109 for the period from
inception on July 16, 1998 through December 31, 1999, the deferred tax asset
generated, primarily from temporary differences related to the treatment of
start-up costs, unearned compensation and from net operating loss carry
forwards, would have been offset by a full valuation allowance.

LIQUIDITY AND CAPITAL RESOURCES

    Since inception, we have financed our operations through capital
contributions from our owners and through debt financing provided by Nortel. As
of December 31, 1999, we had a $123.0 million senior credit facility with
Nortel, of which $71.9 million had been drawn. On February 8, 2000, we entered
into an Amended and Restated Credit Agreement (the Agreement) to increase the
facility to $250.0 million. The terms of the facility do not require cash
interest payments until the earlier of:

     o    February 2001, only if we have not borrowed at least $100.0 million
          under the Nortel financing by that time;

     o    February 2002; and

     o    the date the Tranche C Commitment is fully funded.

Principal payments are scheduled to begin on the earlier of:

     o    June 30, 2001, only if we have not borrowed at least $100.0 million
          under the Nortel financing by February 2001; and

     o    December 31, 2002.

    Our financing with Nortel will be used to purchase equipment, pay interest
and cover approved working capital costs. With the increase of the credit
facility to $250 million, we are required to purchase a total of $167.0 million
of equipment and services from Nortel, and as of December 31, 1999, we had
remaining commitments of $117.6 million. In connection with the facility, we
were to issue springing warrants representing 2% of our outstanding common stock
to Nortel that came into existence and became exercisable on the second
anniversary of the closing of the facility unless we meet specified conditions
prior to that date. Upon completion of our offering of senior discount notes, we
prepaid $75.0 million of indebtedness under the Nortel financing, which
eliminated the issuance of the warrants to Nortel. For more information on the
financing facility, see "-- Description of Our Indebtedness: The Nortel Credit
Facility."

    Net cash used in operating activities was $127,954 for the inception period
ending December 31, 1998, and $17,089,704 for the year ended December 31, 1999.
Cash used in operating activities for the periods were attributable to operating
losses and working capital needs.

    Net cash used in investing activities was $1,366,606 for the inception
period ending December 31, 1998, and $77,219,021 for the year ended December 31,
1999. The expenditures were related primarily to the purchase of office
equipment, telephone equipment and network infrastructure needed to begin
construction of our portion of the Sprint PCS network.

    Net cash provided by financing activities was $15,023,637 consisting
primarily of capital contributions for the inception period ending December 31,
1998 and $86,435,359 for the year ended December 31, 1999 consisting primarily
of capital contributions of $22,000,000 and Nortel draws of $65,967,777.

    As of December 31, 1999, the primary sources of liquidity for Alamosa were
$5.7 million in cash and $51.1 million of unused capacity under the $123.0
million Nortel credit facility.



                                       38
<PAGE>   40
    We estimate that we will require approximately $340 million to complete the
current build-out plan and fund working capital losses through the year 2001.
The actual funds required to build-out our portion of the Sprint PCS network and
to fund operating losses and working capital needs may vary materially from this
estimate, and additional funds could be required. For information see "-- Risk
Factors: Risks Particular to Alamosa's Operations -- Failure to obtain
additional capital, if needed to complete the build-out of our portion of the
Sprint PCS network, could cause delay or abandonment of our development plans."
See also "This Annual Report Contains Forward-Looking Statements."

    We include capital leases related to network equipment and build-out in
construction in progress until service has commenced in their respective
markets. Once that service has commenced, those capital leases are reclassified
to property and equipment. At December 31, 1998, capital leases totaled $728,219
and included long-term capital lease obligations of $708,074. At December 31,
1999 the capital leases totaled $848,842 and included long-term capital lease
obligations of $827,024. See "-- Description of Our Indebtedness: The Nortel
Credit Facility." Amortization in the amount of $30,894 was recorded under these
leases through December 31, 1999.

IMPACT OF YEAR 2000 ISSUE ON THE OPERATIONS AND FINANCIAL CONDITION OF ALAMOSA

    The year 2000 issue arises as the result of computer programs having been
written, and systems having been designed, using two digits rather than four to
define the applicable year. Consequently, that software has the potential to
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in a system failure or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send invoices or engage in normal business activities. We did not
experience any significant disruptions at the beginning of 2000.

    We began acquiring items that comprise our internal information technology
systems in late 1998 when we commenced operations. As we purchased those
components, we determined their year 2000 readiness. As a result, our direct
costs with respect to year 2000 compliance have not been significant and we do
not expect any significant costs in the future. Our non-information technology
systems, particularly our network equipment, have been acquired from Nortel and
are susceptible to year 2000 issues. Nortel has represented to us that such
systems are year 2000 ready.

    To determine the state of readiness of our internal systems, we performed
steps that included the following:

     o    the compilation of an inventory of core critical systems and
          applications, facilities and processes;

     o    the review of core critical systems and applications;

     o    the testing and validation of core critical systems and applications;
          and

     o    the development of contingency and continuity plans for all core
          critical systems and applications independent of Sprint PCS.

    We depend on several third-party vendors and providers to operate our
business, particularly Sprint PCS and local exchange carriers. Sprint PCS
provides us with critical back office services as well as access to its network.
We have contacted Sprint PCS and other third party vendors and providers and
believe they are year 2000 compliant.

    While we believe our systems are year 2000 compliant, there is the risk they
may not be compliant. We believe our greatest risk is the failure of the systems
of our third-party vendors or providers. However, should any failure occur that
affects us, we believe it would result in only a temporary disruption of our
service. Should a disruption occur, there could be a material loss of revenue;
however, we do not believe such losses, if any, will be significant.

    We have not experienced any material disruptions of our systems or
operations as a result of the year 2000 issue, nor are we aware of any
disruptions in the systems or operations of Sprint PCS or our third-party
vendors or providers that would have a material effect on us. However, it is
still possible that future problems could arise with respect to the year 2000
issue.

INFLATION

    Management believes that inflation has not had, and is not likely to have, a
material adverse effect on our results of operations.

EFFECT OF RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

    We do not believe that any recently issued accounting pronouncements will
have any material impact on our financial position, results of operations or
cash flows.

DESCRIPTION OF OUR INDEBTEDNESS: THE NORTEL CREDIT FACILITY

    We entered into the original credit facility effective June 10, 1999 with
Nortel for $123.0 million. On February 8, 2000, we entered into an Amended and
Restated Credit Agreement (the "Amended Agreement") with Nortel to increase the
credit facility to $250.0 million. As of December 31, 1999, we had borrowed
$71.9 million under the facility. This facility constitutes senior debt secured
by a first priority security interest in substantially all of our assets,
including all the assets of Texas Telecommunications, LP and Alamosa Wisconsin
Limited Partnership, our operating subsidiaries. This facility is between
Nortel, as lender and administrative agent, and our subsidiary, Alamosa PCS,
Inc., a Delaware corporation, as borrower. We have agreed, and our current and
future subsidiaries have agreed, to guarantee this facility.

    The Amended Agreement provides for three different tranches of borrowings
evidenced by three promissory notes totaling $250.0 million. The Tranche A
Commitment and Tranche A Note provide for borrowings up to $167.0 million, the
Tranche B Commitment and Tranche B Note provide for borrowings up to $58.0
million and the Tranche C Commitment and Tranche C Note provide for borrowings
up to $25.0 million. This facility is used to purchase equipment and services
from Nortel, to fund other costs of the build-out of our portion of the Sprint
PCS network and to fund costs associated with the financing. Nortel is the
primary vendor of the equipment and services necessary to install our portion of
the Sprint PCS network. Pursuant to our equipment agreement with Nortel, we are
required to purchase a total of $167.0 million of equipment and services from
Nortel, $117.6 million of which we were still required to purchase as of
December 31, 1999. See "Item 1. Business -- Network Operations -- Nortel
Equipment Agreement."

    We have multiple interest rate options available under the credit agreement.
At the termination of the Tranche A and Tranche B Commitments, we must begin to
repay, in quarterly installments, the principal of all borrowings made under
that commitment. A fixed percentage is due each quarter. Any principal that has
not been paid by the maturity date is due at that time. We may voluntarily
prepay any of the loans at any time, but any amount repaid may not be reborrowed
since there are no revolving credit features. We also must make mandatory
prepayments under certain circumstances.

    We are required to pay an origination fee of $3.8 million and a fee on the
unfunded portion of each commitment. We must also pay a separate, annual agent's
fee of $35,000 to the administrative agent.

    The Nortel financing is secured by:

     o    a perfected first priority lien on substantially all of Alamosa PCS
          Holdings, Inc.'s, Alamosa PCS, Inc.'s and the operating subsidiaries'
          current and future assets, and the assets of future subsidiaries;

     o    a collateral assignment of our affiliation agreements with Sprint PCS;

     o    a pledge by Alamosa PCS Holdings, Inc. to Nortel of shares of
          Borrower's capital stock owned by Alamosa and by Borrower of its
          ownership interests in the operating subsidiaries; and

     o    guarantees from Alamosa PCS Holdings, Inc., the operating subsidiaries
          and all future direct or indirect subsidiaries of Alamosa PCS, Inc.

    We are obligated to grant to the administrative agent a first lien mortgage
on any real property we acquire, together with a mortgagee policy of title
insurance, a survey, an appraisal and an environmental survey.

                                       40
<PAGE>   42

    As a closing condition of the credit facility, we were required to
contribute $215 million in equity capital to Alamosa PCS, Inc. This was met with
our initial public offering and issuance of senior discount notes in February
2000. We then contributed $215 million of the proceeds to Alamosa PCS, Inc.

    Alamosa PCS, Inc. must meet certain conditions before it may obtain any
future borrowings under the credit agreement, including, but not limited to,
that there has been no event of default, a reaffirmation of representations, and
that Alamosa PCS, Inc. has a debt to contributed capital ratio of less than or
equal to 1.5 to 1.

    Alamosa PCS, Inc. is subject to financing and operating covenants including,
but not limited to, a maximum ratio of total debt to total capitalization, a
maximum ratio of total debt to annualized earnings before interest, taxes,
depreciation and amortization, referred to as EBITDA, for each quarter and
minimum number of subscribers.

    In addition to failing to perform, observe or comply with the covenants,
agreements and terms of the credit agreement, it is an event of default under
the credit agreement if any party with financial responsibility for the loans or
the outstanding, unsecured equity commitments, or Sprint PCS signatory to the
management agreement with Sprint PCS becomes insolvent, commences or suffers
bankruptcy proceedings or suffers other indicia of extreme financial duress.
Other events of default include, but are not limited to, an attachment against
Alamosa PCS, Inc.'s or its subsidiaries' property that is not released within 30
days and the amount of the proceedings is greater than $500,000 and a judgment
against Alamosa PCS, Inc. or its subsidiaries of greater than $500,000.

CONSENT AND AGREEMENT FOR THE BENEFIT OF THE HOLDERS OF THE NORTEL FINANCING

    Sprint PCS has entered into a consent and agreement with Nortel, which has
been acknowledged by Alamosa, that modifies Sprint PCS's rights and remedies
under our affiliation agreements with Sprint PCS for the benefit of Nortel and
future holders of the Nortel senior financing and any refinancing thereof, which
was a condition to the funding of any amounts under the Nortel financing. The
consent and agreement with Nortel generally provides, among other things, Sprint
PCS's consent to the pledge of substantially all of our assets, including our
rights in our affiliation agreements with Sprint PCS, and that our affiliation
agreements with Sprint PCS generally may not be terminated by Sprint PCS until
the Nortel financing is satisfied in full pursuant to the terms of the consent
and agreement with Nortel.

    Subject to the requirements of applicable law, so long as the Nortel
financing remains outstanding, Sprint PCS has the right to purchase our
operating assets or the partnership interests of our operating subsidiaries,
upon its receipt of notice of an acceleration of the Nortel financing, under
certain terms.

    If Sprint PCS does not purchase our operating assets or the partnership
interests of our operating subsidiaries after an acceleration of the obligations
under the Nortel financing, then the administrative agent may sell the operating
assets or partnership interests.

DESCRIPTION OF OUR INDEBTEDNESS: SENIOR DISCOUNT NOTES

    We raised $187.1 million through a public offering of our senior discount
notes. The senior discount notes are unsecured obligations, rank equally with
all our existing and future senior debt and rank senior to all our existing and
future subordinated debt.

    The senior discount notes are fully and unconditionally, jointly and
severally guaranteed on a senior subordinated basis by our current subsidiaries
and our future restricted subsidiaries. See "Item 1. Business -- Our Background"
regarding the ownership structure of our subsidiaries. The guarantees are
unsecured obligations and:

     o    are subordinate to each subsidiary guarantor's obligations under the
          Nortel financing and other credit facilities with banks or
          institutional lenders;

     o    rank equally with all existing and future senior subordinated debt of
          each subsidiary guarantor; and

     o    are senior to all existing and future subordinated debt of each
          subsidiary guarantor.

    We may redeem some or all of the senior discount notes beginning in 2005,
and until 2003 we may redeem a portion of the senior discount notes with the net
proceeds of an equity offering.

                                       41

<PAGE>   43
    The senior discount notes were issued at a discount to their principal
amount and accrete in value  until 2005, at which time their accreted value will
equal their principal amount. Interest will begin to accrue at this time and
will be payable semi-annually. The senior discount notes contain covenants
limiting our ability and the ability of our subsidiaries to:

     o    incur additional debt or issue preferred stock;

     o    pay dividends, redeem capital stock or make other restricted payments
          or investments;

     o    create liens on assets;

     o    merge, consolidate or dispose of assets;

     o    enter into transactions with affiliates; and

     o    change lines of business.

    Holders of the senior discount notes have the right to require us to
repurchase all or any part of their senior discount notes, at 101% of the
accreted value, if before 2005, or 101% of the aggregate principal amount
thereafter, together with accrued and unpaid interest, upon a change of control
of Alamosa.

    Events of default in respect of the senior discount notes include, among
others, failure to pay interest or principal on the senior discount notes when
due, failure to perform covenants, acceleration of the maturity of other debt,
events of bankruptcy, certain judgments against us and the occurrence of any
event of default pursuant to our affiliation agreements with Sprint PCS.

    We anticipate that the proceeds from our offering of senior discount notes
will not be needed to fund the required capital expenditures, working capital
requirements, operating losses and other cash needs of our current business
plan. We used a portion of the proceeds of that offering to prepay $75.0 million
of indebtedness outstanding under the Nortel facility (and under the
circumstances provided for in the credit agreement, we may borrow those prepaid
amounts in the future). We may decide to use the remaining proceeds of that
offering to:

     o    accelerate coverage within our existing territory

     o    build-out additional areas within our existing territory;

     o    expand our existing territory;

     o    pursue additional telecommunications business opportunities or acquire
          other telecommunications businesses or assets; or

     o    cover general corporate purposes.

    However, if we do not use the remaining proceeds of our notes offering for
these purposes, we may decide to:

     o    prepay additional debt outstanding under the Nortel facility; or

     o    avoid drawing additional amounts under the Nortel facility.

RISK FACTORS: RISKS RELATED TO OUR RELATIONSHIP WITH SPRINT PCS

    We operate in a changing environment that involves numerous risks, some of
which are beyond our control. The following highlights some of these risks.

THE TERMINATION OF OUR AFFILIATION AGREEMENTS WITH SPRINT PCS WOULD SEVERELY
RESTRICT OUR ABILITY TO CONDUCT OUR BUSINESS

    Our relationship with Sprint PCS is governed by our affiliation agreements
with Sprint PCS. Since we do not own any licenses to operate a wireless network,
our business depends on the continued effectiveness of those affiliation
agreements. However, Sprint PCS can terminate our affiliation agreements if we
materially breach them. Among other things, a failure to meet the build-out
requirements for any one of the individual markets in our territory or a failure
to meet Sprint PCS's technical or customer service requirements would constitute
a material breach of our management agreement with Sprint PCS that could lead to
its termination. If Sprint PCS terminates any of our affiliation agreements, we
would no longer be a part of the Sprint PCS network and would have extreme
difficulty conducting our business.

IF SPRINT PCS DOES NOT RENEW OUR AFFILIATION AGREEMENTS WITH THEM, OUR ABILITY
TO CONDUCT OUR BUSINESS WOULD BE SEVERELY RESTRICTED

    Our affiliation agreements with Sprint PCS are not perpetual, and will
eventually expire. Sprint PCS can choose not to renew these agreements at the
expiration of the 20-year initial term or any ten-year renewal term. If Sprint
PCS decides not to renew our affiliation agreements with them, we would no
longer be a part of the Sprint PCS network and would have extreme difficulty
conducting our business.

PROVISIONS OF OUR AFFILIATION AGREEMENTS WITH SPRINT PCS MAY DIMINISH OUR VALUE
AND RESTRICT THE SALE OF OUR BUSINESS

    Under specific circumstances and without further stockholder approval,
Sprint PCS may purchase our operating assets or capital stock for 72% or 80%,
depending on the circumstances, of the "entire business value" of Alamosa, which
value includes the spectrum licenses, business operations and other assets more
fully described in "Item 1. Business -- Our Affiliation Agreements with Sprint
PCS -- The Management Agreement -- Determination of Entire Business Value."
Sprint PCS must approve any change of control of our ownership and consent to
any assignment of our affiliation agreements with them. In addition, Sprint PCS
has a right of first refusal if we decide to sell our operating assets to a
third party. We are also subject to a number of restrictions on the transfer of
our business, including a prohibition on the sale of Alamosa or our operating
assets to competitors of Sprint or Sprint PCS. These restrictions and other
restrictions in our affiliation agreements with Sprint PCS could adversely
affect the value of our common stock, may limit our ability to sell the
business, may reduce the value a buyer would be willing to pay for our business
and may reduce the "entire business value" of Alamosa.

SPRINT PCS MAY MAKE DECISIONS THAT COULD INCREASE OUR EXPENSES, REDUCE OUR
REVENUES OR MAKE OUR AFFILIATE RELATIONSHIP WITH THEM LESS COMPETITIVE

    Sprint PCS, under our affiliation agreements with them, has a substantial
amount of control over the conduct of our business. Accordingly, Sprint PCS may
make decisions that adversely affect our business, such as the following:

     o    Sprint PCS prices its national plans based on its own objectives and
          could set price levels that may not be economically sufficient for our
          business.

     o    Sprint PCS could change the per minute rate for Sprint PCS roaming
          fees and increase the costs for Sprint PCS to perform back office
          services.

     o    Sprint PCS could withhold its consent, which is required for us to
          sell non-Sprint PCS approved equipment.

     o    Sprint PCS may alter its network and technical requirements or request
          that we build-out additional areas within our territory, which could
          result in increased equipment and build-out costs or in Sprint PCS
          building-out that area itself or assigning it to another affiliate.

                                       43
<PAGE>   45

    A CHANGE OF CONTROL OF SPRINT OR SPRINT PCS MAY RESULT IN A NAME CHANGE OR
COULD INCREASE THE LIKELIHOOD THAT OUR AFFILIATION AGREEMENTS WILL NOT BE
RENEWED

    Sprint or Sprint PCS may experience a change of control, sale or merger that
could adversely affect our relationships with them or result in a name change.
MCI WorldCom Inc. and Sprint have announced a proposed merger in which owners of
each class of Sprint's common stock would exchange their Sprint stock for MCI
common stock. If the merger is completed, we expect that our affiliation
agreements with the merged company would be on the same terms as our current
affiliation agreements with Sprint PCS. However, the consummation of the merger
may increase the likelihood that our affiliation agreements will not be renewed
if, among other reasons, the combined company has a different strategy related
to affiliate relationships. Additionally, we may lose the use of the
recognizable Sprint and Sprint PCS brand names if the merger results in a name
change.

PROBLEMS EXPERIENCED BY SPRINT PCS WITH ITS INTERNAL SUPPORT SYSTEMS COULD LEAD
TO CUSTOMER DISSATISFACTION OR INCREASE OUR COSTS

    We rely on Sprint PCS's internal support systems, including customer care,
billing and back-office support. As Sprint PCS has expanded, its internal
support systems have been subject to increased demand and, in some cases,
suffered a degradation in service. We cannot assure you that Sprint PCS will be
able to successfully add system capacity or that its internal support systems
will be adequate. It is likely that problems with Sprint PCS's internal support
systems could cause:

     o    delays or problems in our own operations or service;

     o    delays or difficulty in gaining access to customer and financial
          information, which we are currently experiencing with respect to our
          direct electronic access to significant aspects of Sprint PCS's
          internal support systems and financial data;

     o    a loss of Sprint PCS customers; and

     o    an increase in the costs of customer care, billing and back office
          services.

OUR COSTS FOR INTERNAL SUPPORT SYSTEMS MAY INCREASE IF SPRINT PCS TERMINATES OUR
SERVICES AGREEMENT

    We estimate that our costs for the services provided to us by Sprint PCS
under our services agreement in the year 2000 will be approximately $12 million.
We expect this number to significantly increase as the number of Sprint PCS
subscribers based in our territory increases. Our services agreement with Sprint
PCS provides that, upon nine months' prior written notice, Sprint PCS may
terminate any service provided under that agreement. We do not have a
contingency plan if Sprint PCS terminates any such service. If Sprint PCS
terminates a service for which we have not developed a cost-effective
alternative or increases the amount it charges us for these services, our
operating costs may increase beyond our expectations and our operations may be
interrupted or restricted.

WE MAY HAVE DIFFICULTY IN OBTAINING HANDSETS AND EQUIPMENT, WHICH ARE IN SHORT
SUPPLY

    We depend on our relationship with Sprint PCS to obtain handsets and
equipment. The demand for the equipment we require to construct our portion of
the Sprint PCS network is considerable, and manufacturers of this equipment have
substantial order backlogs. In addition, the demand for specific types of
handsets is strong and the manufacturers of those handsets may have to
distribute their limited supply of products among the manufacturers' numerous
customers. If Sprint PCS modifies its handset logistics and delivery plan or if
we are not able to continue to rely on Sprint PCS's relationships with suppliers
and vendors, some of which provide us with vendor discounts on equipment, we
could have difficulty obtaining specific types of handsets and equipment in a
timely manner and our equipment costs would increase. As a result, we could
suffer delays in the build-out of our portion of the Sprint PCS network,
disruptions in service and a reduction in subscribers.

                                       44
<PAGE>   46

IF WE FAIL TO PAY OUR DEBT, OUR LENDERS MAY SELL OUR LOANS TO SPRINT PCS AND
GIVE SPRINT PCS RIGHTS OF A CREDITOR TO FORECLOSE ON OUR ASSETS

    Sprint PCS has contractual rights to purchase Nortel's rights as a senior
lender under the Nortel financing documents. These rights are triggered by an
acceleration of the maturity of the Nortel financing. To the extent Sprint PCS
purchases these obligations, Sprint PCS's interests as a creditor could conflict
with ours. Sprint PCS's rights as a senior lender would enable it to exercise
rights with respect to our assets, including the right to foreclose on those
assets, in a manner not otherwise permitted under our affiliation agreements
with Sprint PCS.

IF SPRINT PCS DOES NOT MAINTAIN CONTROL OVER ITS LICENSED SPECTRUM, OUR
AFFILIATION AGREEMENTS WITH SPRINT PCS MAY BE TERMINATED

    Sprint PCS, not Alamosa, owns the licenses necessary to provide wireless
services in our territory. The Federal Communications Commission requires that
licensees like Sprint PCS maintain control of their licensed systems and not
delegate control to third party operators or managers like Alamosa. Although our
affiliation agreements with Sprint PCS reflect an arrangement that the parties
believe meets the Federal Communications Commission requirements for licensee
control of licensed spectrum, we cannot assure you that the Federal
Communications Commission will agree with us. If the Federal Communications
Commission were to determine that our affiliation agreements with Sprint PCS
need to be modified to increase the level of licensee control, we have agreed
with Sprint PCS to use our best efforts to modify the agreements to comply with
applicable law. If we cannot agree with Sprint PCS to modify the agreements,
they may be terminated. If the agreements are terminated, we would no longer be
a part of the Sprint PCS network and we would have extreme difficulty in
conducting our business.

THE FEDERAL COMMUNICATIONS COMMISSION MAY NOT RENEW THE SPRINT PCS LICENSES,
WHICH WOULD PREVENT US FROM PROVIDING WIRELESS SERVICES

    We do not own any licenses to operate a wireless network. We are dependent
on Sprint PCS's licenses, which are subject to renewal and revocation. Sprint
PCS's licenses in our territory will expire in 2005 or 2007 but may be renewed
for additional ten-year terms. The Federal Communications Commission has adopted
specific standards that apply to wireless personal communications services
license renewals. Any failure by Sprint PCS or us to comply with these standards
could cause revocation or forfeiture of the Sprint PCS licenses for our
territory. Additionally, if Sprint PCS does not demonstrate to the Federal
Communications Commission that Sprint PCS has met the five-year and ten-year
construction requirements for each of its wireless personal communications
services licenses, it can lose those licenses. If Sprint PCS loses its licenses
in our territory for any of these reasons, we would not be able to provide
wireless services without obtaining rights to other licenses.

RISKS PARTICULAR TO ALAMOSA'S OPERATIONS

    BECAUSE OF THE NATURE OF OUR RELATIONSHIP WITH CHR SOLUTIONS, INC., ANY
CONFLICTS THAT ARISE BETWEEN US AND CHR SOLUTIONS COULD NEGATIVELY AFFECT OUR
ABILITY TO EFFECTIVELY CONDUCT OUR BUSINESS

    We rely heavily on CHR Solutions, Inc. for engineering, marketing, operating
and other consulting services. We have paid or will pay CHR Solutions
substantial amounts for these services, including approximately:

     o    $3.8 million paid during 1999;

     o    $3.5 million that we estimate will be paid during 2000;

     o    an aggregate of $7.4 million in current and prior contractual
          commitments beginning in 1998; and

     o    an anticipated additional $5 million in contractual commitments that
          we are currently negotiating with CHR Solutions.

    If CHR Solutions interests become adverse to ours, we may be forced to
acquire consulting services from an alternate source, which could be very
difficult or costly or result in delays in our network build-out. Additionally,
Mr. David Sharbutt, our chairman and chief executive officer, is also a senior
consultant, director and shareholder of CHR Solutions. Consequently, if CHR
Solution's interests become adverse to ours, Mr. Sharbutt may face a conflict of
interest. In addition, although the employment agreement related to Mr.
Sharbutt's position as a senior consultant of CHR Solutions does not specify the
time requirements of his employment, his responsibilities as an employee of


                                       45
<PAGE>   47

CHR Solutions may require significant professional time and effort and may
reduce the time and effort he is able to devote to Alamosa. However, his
employment agreement with us requires Mr. Sharbutt to devote his full time and
effort to the business and affairs of Alamosa. See "Item 13. Certain
Relationships and Related Transactions" for details related to this and other
related party transactions.

OUR STOCKHOLDERS, MEMBERS OF MANAGEMENT AND DIRECTORS MAY BE SUBJECT TO
CONFLICTS OF INTEREST

    Some of our stockholders and members of management have significant
investments in communications services companies that compete with Alamosa. In
addition, several of our directors serve as directors of other communications
services companies. As a result, these persons may be subject to conflicts of
interest because of their investments or status as director that will have to be
resolved by those persons and Alamosa. This conflict could require that such
persons not participate in the decision-making related to, or implementation of,
transactions or issues in which such conflicts arise. For a discussion of the
magnitude of these risks, please see "Item 10. Directors and Executive Officers
of the Registrant" and "Item 13. Certain Relationships and Related
Transactions."

WE HAVE A VERY LIMITED OPERATING HISTORY AND MAY NOT ACHIEVE OR SUSTAIN
OPERATING PROFITABILITY OR POSITIVE CASH FLOWS, WHICH WOULD LIKELY RESULT IN A
DROP IN OUR STOCK PRICE

    Our operating history is very limited. We initiated commercial operations in
our first market in June 1999. We expect to incur significant operating losses
and to generate significant negative cash flow from operating activities at
least through the year ending December 31, 2001. We have already incurred $31.6
million in operating losses through December 31, 1999. Our operating
profitability will depend upon many factors, including, among others, our
ability to market Sprint PCS services, achieve our projected market penetration
and manage customer turnover rates. If we do not achieve and maintain operating
profitability and positive cash flow from operating activities on a timely
basis, our stock price could fall and you could lose all or part of your
investment.

FAILURE TO OBTAIN ADDITIONAL CAPITAL, IF NEEDED TO COMPLETE THE BUILD-OUT OF OUR
PORTION OF THE SPRINT PCS NETWORK, COULD CAUSE DELAY OR ABANDONMENT OF OUR
DEVELOPMENT PLANS

    The build-out of our portion of the Sprint PCS network will require
substantial capital. As of January 1, 2000, we estimated that requirements to
complete the current build-out plan and fund working capital losses through the
year 2001 were approximately $283 million. We plan to finance these requirements
using the funds received from the initial public offering and the remaining
$178.1 million available under the Amended and Restated Nortel Credit Facility.
Additional funds could be required for a variety of reasons, including
unforeseen delays, unanticipated expenses, increased capital requirements,
higher than expected operating losses, engineering design changes and other
technology risks or other corporate purposes. In addition, if we complete our
build-out more rapidly than currently anticipated, or if we contract to develop
additional markets, we will need to raise additional equity or debt capital.
These additional funds may not be available. Even if those funds are available,
we may not be able to obtain them on a timely basis, on terms acceptable to us
or within limitations permitted under our existing debt covenants or the
covenants with respect to the senior discount notes. Failure to obtain
additional funds, should the need for them develop, could result in the delay or
abandonment of our development and expansion plans and we may be unable to fund
our ongoing operations.

BECAUSE WE DEPEND HEAVILY ON OUTSOURCING, THE INABILITY OF THIRD PARTIES TO
FULFILL THEIR CONTRACTUAL OBLIGATIONS TO US MAY DISRUPT OUR SERVICES OR THE
BUILD-OUT OF OUR PORTION OF THE SPRINT PCS NETWORK

    Because we decided to outsource portions of our business, we depend heavily
on third-party vendors, suppliers, consultants, contractors and local exchange
carriers. We have retained those persons to:

     o    design and engineer our systems;

     o    construct base stations, switch facilities and towers;

     o    lease base stations;

     o    install T-1 lines; and

     o    deploy our wireless personal communications services network systems.


                                       46
<PAGE>   48

    Specifically, our financing arrangements with Nortel make us especially
dependent on them for network equipment, since we must use a specified amount of
any funds borrowed from Nortel to purchase their equipment. In addition, we
lease almost all of the tower sites for our wireless systems through a master
lease agreement with Specialty Capital Services, Inc., now a subsidiary of
American Tower Corporation. Specialty in turn has separate leasing arrangements
with each of the owners of the sites. If Specialty or American Tower Corporation
were to become insolvent or Specialty were to breach those arrangements, we may
lose access to those base stations and experience extended service interruption
in the areas serviced by those sites. The failure by any of our vendors,
suppliers, consultants, contractors or local exchange carriers to fulfill their
contractual obligations to us could materially delay construction and adversely
affect the operations of our portion of the Sprint PCS network.

OUR ROAMING ARRANGEMENTS MAY NOT BE COMPETITIVE WITH OTHER WIRELESS SERVICE
PROVIDERS, WHICH MAY RESTRICT OUR ABILITY TO ATTRACT AND RETAIN CUSTOMERS

    We rely on roaming arrangements with other wireless service providers for
coverage in some areas. Some risks related to these arrangements are as follows:

     o    the quality of the service provided by another provider during a
          roaming call may not approximate the quality of the service provided
          by Sprint PCS;

     o    the price of a roaming call may not be competitive with prices of
          other wireless companies for roaming calls;

     o    customers may have to use a more expensive dual-band/dual mode handset
          with diminished standby and talk time capacities;

     o    customers must end a call in progress and initiate a new call when
          leaving the Sprint PCS network and entering another wireless network;
          and

     o    Sprint PCS customers may not be able to use Sprint PCS advanced
          features, such as voicemail notification, while roaming.

If Sprint PCS customers are not able to roam instantaneously or efficiently onto
other wireless networks, we may lose current Sprint PCS subscribers and our
Sprint PCS services will be less attractive to new customers.

IF WE RECEIVE LESS REVENUES OR INCUR MORE FEES THAN WE ANTICIPATE FOR SPRINT PCS
ROAMING, WE MAY NOT BE ABLE TO OPERATE OUR BUSINESS PROFITABLY

    We are paid a fee from Sprint PCS or a Sprint PCS affiliate for every minute
that a Sprint PCS subscriber based outside of our territory uses the Sprint PCS
network in our territory. Similarly, we pay a fee to Sprint PCS for every minute
that a Sprint PCS subscriber based in our territory uses the Sprint PCS network
outside our territory. Sprint PCS customers from our territory may spend more
time in other Sprint PCS coverage areas than we anticipate, and Sprint PCS
customers from outside our territory may spend less time in our territory or may
use our services less than we anticipate. As a result, we may receive less
Sprint PCS roaming revenue than we anticipate or we may have to pay more Sprint
PCS roaming fees than we collect. In addition, Sprint PCS could change the
current fee for each Sprint PCS roaming minute used. If we were to receive less
Sprint PCS roaming net revenue, we may not be able to operate our business
profitably. For more information on roaming, see "Item 1. Business -- Roaming."

WE ARE LIKELY TO RECEIVE VERY LITTLE NON-SPRINT PCS ROAMING REVENUE SINCE THE
SPRINT PCS NETWORK IS NOT COMPATIBLE WITH MANY OTHER NETWORKS

    A portion of our revenue may be derived from payments by other wireless
service providers for use by their subscribers of the Sprint PCS network in our
territory. However, the technology used in the Sprint PCS network is not
compatible with the technology used by many other systems, which diminishes the
ability of other wireless service providers' subscribers to use our services.
Sprint PCS has entered into few agreements that enable customers of other
wireless service providers to roam onto the Sprint PCS network. As a result, the
actual non-Sprint PCS roaming revenue that we receive in the future is likely to
be low relative to other wireless service providers. For more information on
roaming, see "Item 1. Business -- Roaming." For further information on the
Sprint PCS network technology, see "Item 1. Business -- Technology."

<PAGE>   49

OUR RAPID GROWTH MAY IMPAIR OUR ABILITY TO EXPAND OUR COVERAGE AND MANAGE OUR
SYSTEMS

    Since our inception in July 1998, we have experienced rapid growth and
 development in a relatively short period of time. As we open more markets, we
expect to continue to experience growth. The management of that growth will
require, among other things:

     o    continued development of our operational and administrative systems;

     o    stringent control of costs of network build-out;

     o    integration of our network infrastructure with the rest of the Sprint
          PCS network;

     o    increased marketing activities;

     o    the ability to attract and retain qualified management, technical and
          sales personnel; and

     o    the training of new personnel.

    Failure to successfully manage our expected rapid growth and development
could impair our ability to complete the build-out of our portion of the Sprint
PCS network, manage the expanding systems in our territory and achieve
profitability.

OUR PROJECTED BUILD-OUT PLAN DOES NOT COVER ALL OF OUR TERRITORY, WHICH COULD
MAKE IT DIFFICULT TO MAINTAIN A PROFITABLE CUSTOMER BASE

    Our projected build-out plan for our territory does not cover all areas of
our territory. Upon completion of our current build-out plan, we expect to cover
65% of the resident population in our territory. As a result, our plan may not
adequately serve the needs of the potential customers in our territory or
attract enough subscribers to operate our business successfully. To correct this
potential problem, we may have to cover a greater percentage of our territory
than we anticipate, which we may not have the financial resources to complete or
may be unable to do profitably.

PARTS OF OUR TERRITORY HAVE LIMITED LICENSED SPECTRUM, AND THIS MAY AFFECT THE
QUALITY OF OUR SERVICE OR RESTRICT OUR ABILITY TO PURCHASE SPECTRUM LICENSES
FROM SPRINT PCS IN THOSE AREAS

    While Sprint PCS has licenses to use 30 MHz of spectrum throughout most of
our territory, it has licenses covering only 10 MHz in New Mexico and Durango
and 20 MHz in El Paso. In the future, as the number of subscribers in those
areas increases, this limited licensed spectrum may not be able to accommodate
increases in call volume and may lead to more dropped calls than in other parts
of our territory. In addition, Sprint PCS has no obligation to sell us spectrum
licenses in areas where Sprint PCS owns less than 20 MHz of spectrum.
Accordingly, if Sprint PCS were to terminate our affiliation agreements with
them, it is likely that we would be unable to operate our business in New Mexico
and Durango.

THE TECHNOLOGY WE USE MAY BECOME OBSOLETE OR LIMIT OUR ABILITY TO COMPETE
EFFECTIVELY WITHIN THE WIRELESS INDUSTRY

    The wireless telecommunications industry is experiencing significant
technological change. We employ code division multiple access digital
technology, the digital wireless communications technology selected by Sprint
PCS for its network. Code division multiple access technology may not provide
the advantages expected by us or Sprint PCS. If another technology becomes the
preferred industry standard, we would be at a competitive disadvantage and
competitive pressures may require Sprint PCS to change its digital technology.
We may be unable to respond to these pressures and implement new technology on a
timely basis or at an acceptable cost. For more information on technology,
including code division multiple access technology, see "Item 1. Business --
Technology."

UNAUTHORIZED USE OF, OR INTERFERENCE WITH, THE SPRINT PCS NETWORK COULD DISRUPT
OUR SERVICE AND INCREASE OUR COSTS

    We may incur costs associated with the unauthorized use of the Sprint PCS
network including administrative and capital costs associated with detecting,
monitoring and reducing the incidence of fraud. Fraudulent use of the Sprint PCS
network may impact interconnection costs, capacity costs, administrative costs,
fraud prevention costs and payments to other carriers for unbillable fraudulent
roaming. In addition, our border markets are susceptible to uncertainties
related to areas not governed by the Federal Communications Commission. For
example, unauthorized microwave radio signals near the border in Mexico could
disrupt our service in the United States.

RISK FACTORS: RISKS PARTICULAR TO ALAMOSA'S INDEBTEDNESS

WE HAVE SUBSTANTIAL DEBT AND EXPECT TO INCUR SUBSTANTIAL ADDITIONAL DEBT, WHICH
WILL REQUIRE LARGE PAYMENTS AND MAY RESULT IN OUR LENDERS CONTROLLING OUR ASSETS

    As of December 31, 1999, our outstanding long-term debt totaled $72.8
million. In addition, under our current business plan, we expect to incur
substantial additional debt, including $187.1 million from our senior discount
notes offering, before achieving break-even operating cash flow.

    Our substantial debt will have a number of important consequences for our
operations and our investors, including the following:

     o    we will have to dedicate a substantial portion of any cash flow from
          operations to the payment of interest on, and principal of, our debt,
          which will reduce funds available for other purposes;

     o    we may not have sufficient funds to pay interest on, and principal of,
          our debt; and

     o    due to the liens on substantially all of our assets that secure our
          senior debt, lenders or holders of our senior debt may control our
          assets or our subsidiaries' assets upon a default.

IF WE DO NOT MEET ALL OF THE CONDITIONS REQUIRED UNDER OUR NORTEL FINANCING
AGREEMENTS, WE MAY NOT BE ABLE TO DRAW DOWN ALL OF THE FUNDS WE ANTICIPATE
RECEIVING FROM NORTEL AND MAY NOT BE ABLE TO COMPLETE THE BUILD-OUT OF OUR
PORTION OF THE SPRINT PCS NETWORK

    We have received $71.9 million as of December 31, 1999 under our financing
agreements with Nortel. The remaining $178.1 million, which we expect to receive
in the future, is subject at each funding date to several conditions, including:

     o    acquiring minimum numbers of Sprint PCS subscribers;

     o    providing coverage to a minimum number of residents; and

     o    adhering to financial covenants.

    If we do not meet these conditions at each funding date, Nortel may choose
not to lend any or all of the remaining amounts. If other sources of funds are
not available, we may be unable to complete the build-out of our portion of the
Sprint PCS network. If we do not have sufficient funds to complete our network
build-out, we may be in breach of our management agreement with Sprint PCS and
be in default under our financing from Nortel.

IF WE DO NOT HAVE ACCESS TO THE CAPITAL MARKETS ON TERMS REASONABLY SATISFACTORY
TO US, WE MAY BE UNABLE TO REPAY THE NORTEL FACILITY AT MATURITY, OR REFINANCE
THE NORTEL FACILITY BEFORE WE ARE REQUIRED TO ISSUE WARRANTS TO NORTEL

    Failure to repay the Nortel facility at maturity will result in a default
under that agreement. It is unlikely that we can repay the Nortel facility
without refinancing the facility, and we may have inadequate access to the
capital markets to permit such refinancing. A default under the Nortel facility
could:

     o    prevent us from operating or completing the build-out of our portion
          of the Sprint PCS network;

                                       49
<PAGE>   51

     o    constitute a default under the senior discount notes or a default
          under our affiliation agreements with Sprint PCS; and

     o    could make it extremely difficult for us to obtain any future
          financing.

    If we are unable to refinance and repay a portion of the Nortel financing
prior to the second anniversary of the closing date of the Nortel facility, we
will likely be required to issue warrants to purchase shares of our stock to
Nortel, which would be dilutive to our stockholders if Nortel exercises those
warrants.

OUR NEW INDEBTEDNESS WILL PLACE RESTRICTIONS ON US WHICH MAY LIMIT OUR OPERATING
FLEXIBILITY AND OUR ABILITY TO PAY DIVIDENDS

    The indenture governing the senior discount notes impose material operating
and financial restrictions on us. These restrictions, subject to ordinary course
of business exceptions, may limit our ability to engage in some transactions,
including the following:

     o    consummating designated types of mergers or consolidations;

     o    paying dividends or other distributions to our stockholders;

     o    making investments;

     o    selling assets;

     o    repurchasing our common stock;

     o    changing lines of business;

     o    borrowing additional money; and

     o    engaging in transactions with affiliates.

    These restrictions could limit our ability to obtain debt financing,
repurchase stock, refinance or pay principal or interest on our outstanding
debt, consummate acquisitions for cash or debt or react to changes in our
operating environment.

RISK FACTORS:  INDUSTRY RISKS

WE MAY EXPERIENCE A HIGH RATE OF CUSTOMER TURNOVER WHICH WOULD INCREASE OUR
COSTS OF OPERATIONS AND REDUCE OUR REVENUE

    The wireless personal communications services industry in general and Sprint
PCS in particular have experienced a higher rate of customer turnover as
compared to cellular industry averages. In particular, our customer turnover may
be high because:

     o    Sprint PCS does not require its customers to sign long term contracts;
          and

     o    Sprint PCS's handset return policy allows customers to return used
          handsets within 30 days of purchase and receive a full refund.

    A high rate of customer turnover could adversely affect our competitive
position, results of operations and our costs of, or losses incurred in,
obtaining new subscribers, especially because we subsidize some of the costs of
initial purchases of handsets by customers.


                                       50
<PAGE>   52

REGULATION BY GOVERNMENT AGENCIES AND TAXING AUTHORITIES MAY INCREASE OUR COSTS
OF PROVIDING SERVICE OR REQUIRE US TO CHANGE OUR SERVICES

    Our operations and those of Sprint PCS may be subject to varying degrees of
regulation by the Federal Communications Commission, the Federal Trade
Commission, the Federal Aviation Administration, the Environmental Protection
Agency, the Occupational Safety and Health Administration and state and local
regulatory agencies and legislative bodies. Adverse decisions or regulations of
these regulatory bodies could negatively impact Sprint PCS's operations and our
costs of doing business. For example, changes in tax laws or the interpretation
of existing tax laws by state and local authorities could subject us to
increased income, sales, gross receipts or other tax costs or require us to
alter the structure of our current relationship with Sprint PCS.

CONCERNS OVER HEALTH RISKS POSED BY THE USE OF WIRELESS HANDSETS MAY REDUCE THE
CONSUMER DEMAND FOR OUR SERVICES

    Media reports have suggested that radio frequency emissions from wireless
handsets may:

     o    be linked to various health problems resulting from continued or
          excessive use, including cancer;

     o    interfere with various electronic medical devices, including hearing
          aids and pacemakers; and

     o    cause explosions if used while fueling an automobile.

    Widespread concerns over radio frequency emissions may expose us to
potential litigation or discourage the use of wireless handsets. Any resulting
decrease in demand for our services could impair our ability to profitably
operate our business.

WORSE THAN EXPECTED FOURTH QUARTER RESULTS MAY CAUSE OUR STOCK PRICE TO DROP AND
SIGNIFICANTLY REDUCE OUR OVERALL RESULTS OF OPERATIONS

    The wireless industry is heavily dependent on fourth quarter results. Among
other things, the industry relies on significantly higher customer additions and
handset sales in the fourth quarter as compared to the other three fiscal
quarters.

    The price of our common stock may drop and our overall results of operations
could be significantly reduced if Alamosa has a worse than expected fourth
quarter for any reason, including the following:

     o    Alamosa's inability to match or beat pricing plans offered by
          competitors;

     o    the failure to adequately promote Sprint PCS's products, services and
          pricing plans;

     o    the inability of Alamosa to obtain an adequate supply or selection of
          handsets;

     o    a downturn in the economy of some or all markets in our territory; or

     o    a poor holiday shopping season.

SIGNIFICANT COMPETITION IN THE WIRELESS COMMUNICATIONS SERVICES INDUSTRY MAY
RESULT IN OUR COMPETITORS OFFERING NEW SERVICES OR LOWER PRICES THAT WOULD
PREVENT US FROM OPERATING PROFITABLY

    Competition in the wireless communications services industry is intense. We
anticipate that competition will cause the market prices for two-way wireless
products and services to decline in the future. Our ability to compete will
depend, in part, on our ability to anticipate and respond to various competitive
factors affecting the telecommunications industry.

    Our dependence on Sprint PCS to develop competitive products and services
and the requirement that we obtain Sprint PCS's consent to sell non-Sprint PCS
approved equipment may limit our ability to keep pace with our competitors on
the introduction of new products, services and equipment. Some of our
competitors are larger than us, with greater resources and more extensive
coverage areas, and may market other services, such as landline



                                       51
<PAGE>   53

telephone service, cable television and Internet access, with their wireless
communications services. In addition, we may be at a competitive disadvantage
since we may be more highly leveraged than some of our competitors.

    Furthermore, there has been a recent trend in the wireless communications
industry towards consolidation of wireless service providers through joint
ventures, mergers and acquisitions. We expect this consolidation to lead to
larger competitors over time. We may be unable to compete successfully with
larger competitors who have substantially greater resources or who offer more
services than we do. For more information on the competition we face in the
wireless communications industry, see "Item 1. Business -- Competition."

A LACK OF SUITABLE TOWER SITES MAY DELAY THE BUILD-OUT OF OUR PORTION OF THE
SPRINT PCS NETWORK AND RESTRICT OUR OPERATING CAPACITY

    A lack of tower site availability due to difficulty in obtaining local
regulatory approvals or other reasons may delay the build-out of our portion of
the Sprint PCS network, delay the opening of markets, limit network capacity or
reduce the number of new Sprint PCS subscribers. The local governmental
authorities in various locations in our territory have at times placed
moratoriums on the construction of additional towers and base stations. These
moratoriums may materially and adversely affect the timing of the planned
build-out and quality of the network operations in those markets. We have
experienced difficulty, and may continue to have difficulty, in obtaining tower
sites in some areas of our territory on a timely basis.

RISK FACTORS:  RISKS RELATING TO OUR STOCK

OUR EXISTING STOCKHOLDERS, DIRECTORS AND OFFICERS MAY BE ABLE TO CONTROL THE
OUTCOME OF SIGNIFICANT MATTERS PRESENTED TO STOCKHOLDERS FOLLOWING THE
COMPLETION OF OUR INITIAL PUBLIC OFFERING

    Our existing stockholders, directors and officers beneficially own
approximately 84% of our outstanding common stock on a diluted basis.
Consequently, those persons, if they act as a group, are able to control the
outcome of matters submitted for stockholder action, including the election of
members to our board of directors and the approval of significant change in
control transactions. This may have the effect of delaying or preventing a
change in control even though a change in ownership may be economically
beneficial to us and our stockholders. For more information on this subject,
please refer to "Item 10. Directors and Executive Officers of the Registrant"
and "Item 12. Security Ownership of Certain Beneficial Owners and Management."

ACTUAL OR ANTICIPATED SALES OF OUR COMMON STOCK BY OUR CURRENT STOCKHOLDERS
COULD CAUSE THE MARKET PRICE OF OUR COMMON STOCK TO DECREASE

    Many of our current stockholders hold large portions of our common stock. In
August 2000, approximately 47,763,659 shares of our common stock, including
shares issuable pursuant to stock options immediately exercisable or exercisable
prior to the termination of the lock-up period, will no longer have transfer
restrictions imposed by a lock-up period. On February 8, 2001, approximately
48,500,008 shares of common stock will be eligible for sale pursuant to Rule 144
of the Securities Act. The occurrence of sales of a large number of these
shares, or the perception that these sales could occur, could cause a drop in
our stock price and could impair our ability to obtain capital through an
offering of equity securities.

ANTI-TAKEOVER PROVISIONS IN OUR CHARTER AND BYLAWS COULD LIMIT OUR SHARE PRICE
AND DELAY A CHANGE IN CONTROL OF ALAMOSA

    Our certificate of incorporation provides that our board of directors may
issue preferred stock without stockholder approval. In addition, our bylaws
provide for a classified board, with each board member serving a three-year
term. These provisions, among others, may have the effect of discouraging a
third party from making a tender offer or otherwise attempting to obtain control
of Alamosa, even though a change in ownership might be economically beneficial
to us and our stockholders.

    ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

    We do not engage in commodity futures trading activities and do not enter
into derivative financial instrument transactions for trading or other
speculative purposes. We also do not engage in transactions in foreign
currencies that could expose us to market risk.

(1) These amounts represent the estimated minimum annual payments due under our
    estimated capital lease obligations for the periods presented.

(2) The amounts represent estimated year-end balances under the Nortel facility
    based on a projection of the funds borrowed under that facility pursuant to
    our current plan of network build-out.

(3) Interest rate on the Nortel financing equals, at our option, either the
    London Interbank Offered Rate (LIBOR) + 3.75%, or the prime or base rate of
    Citibank, N.A. plus 2.75%. LIBOR is assumed to equal 6.0% for all periods
    presented.

    Our primary market risk exposure relates to:

     o    the interest rate risk on long-term and short-term borrowings;

     o    our ability to refinance our senior discount notes at maturity at
          market rates; and

     o    the impact of interest rate movements on our ability to meet interest
          expense requirements and meet financial covenants.

    The carrying value of the financial instruments approximates fair value.

    As a condition to the Nortel financing, we must maintain one or more
interest rate protection agreements in an amount equal to 50% of the total debt
under the financing. We do not hold or issue financial or derivative financial
instruments for trading or speculative purposes. While we cannot predict our
ability to refinance existing debt or the impact that interest rate movements
will have on our existing debt, we continue to evaluate our financial position
on an ongoing basis.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Exchange Act requires our directors and executive
officers and persons who beneficially own more than 10% of our common stock to
file reports of ownership and changes in ownership with the Securities and
Exchange Commission. Because we were not a reporting company during fiscal year
1999, no reports were required that year. Accordingly, we believe that we fully
complied with any reporting requirements of Section 16(a).

BENEFIT PLANS

1999 LONG-TERM INCENTIVE PLAN

     o    nonqualified stock options;

     o    tandem and independent stock appreciation rights;

     o    stock bonuses; and

     o    restricted stock.

     The aggregate number of shares of common stock that may be issued under the
plan is 7,000,000. We have granted options effective as of the closing of the
initial public offering to purchase 5,554,000 shares of our common stock with an
exercise price equal to the initial public offering price per share to
directors, officers, employees and consultants and to purchase 630,500 shares of
our common stock with per share exercise prices ranging from $1.13 to $1.42 to
three of our executive officers, of which options to purchase 533,498 shares
were exercised immediately prior to the initial public offering.

     The option plan is administered by our board of directors or by a stock
option plan committee appointed by our board of directors, which is authorized,
subject to the provisions of the option plan, to grant awards and establish
rules and regulations as it deems necessary for the proper administration of the
option plan and to make whatever determinations and interpretations it deems
necessary or advisable.

     An incentive option may not have an exercise price less than the fair
market value of the common stock on the date of grant or an exercise period that
exceeds ten years from the date of grant and is subject to other limitations
which allow the option holder to qualify for favorable tax treatment.
Nonqualified options may have an exercise price of less than, equal to or
greater than the fair market value of the underlying common stock on the date of
grant but, like incentive options, are limited to an exercise period of no
longer than ten years.

     The committee determines and designates those persons to whom awards are
granted and determines:

     o    the award period;

     o    the date of grant;

     o    the vesting period; and

     o    other terms, provisions, limitations and performance requirements
          approved by the committee, but not inconsistent with the plan.



                                       61
<PAGE>   62



     The committee also has the discretion to reprice stock option awards.

     An option will not be transferable except by will or by the laws of descent
or distribution, unless specified in the plan or determined otherwise by our
board of directors or the committee.

     Awards under the plan may contain provisions that, if a change in control
of Alamosa occurs, give the stock option plan committee discretion to offer to
purchase awards from plan participants and make adjustments or modifications to
outstanding awards to protect and maintain the rights and interests of the plan
participants or take any other action the award agreements may authorize. A
change in control of Alamosa is deemed to occur for purposes of the plan upon
any of the following events:

     o    the approval by our stockholders of a plan to dissolve or liquidate
          Alamosa;

     o    continuing directors, who are persons who were serving on our board of
          directors when the plan was adopted or who afterwards were elected to
          the board of directors by majority of the directors in office, cease
          to constitute at least 50% of the board of directors;

     o    a consolidation or merger in which we do not survive, or in which our
          stockholders do not retain the same proportionate common stock
          ownership in the surviving company after the merger; or

     o    a sale of substantially all of our assets, unless the sale is due to
          the default by us or our affiliates under any:

     o    credit or related agreement among us or our affiliates or successors
          and Nortel Networks, Inc. or any other lender; or

     o    management or related agreement among us or our affiliates or
          successors and Sprint Spectrum, LP, SprintCom, Inc., WirelessCo, LP,
          Sprint Communications Company, LP or their affiliates or successors.

     The events described in the third and fourth bullet points above will not
be deemed a change in control of Alamosa if after the event:

     o    continuing directors constitute at least 50% of the board of directors
          of the continuing, surviving or acquiring entity, or that entity's
          ultimate parent entity if the parent entity has at least a majority of
          the voting power of the entity; and

     o    the continuing, surviving or acquiring entity, or that entity's
          ultimate parent entity, assumes all of the outstanding stock options
          under the plan.

401(k) RETIREMENT PLAN

     We have established a tax-qualified employee savings and retirement plan.
Employees may elect to contribute up to 20% of their annual compensation on a
pre-tax basis and up to an additional 10% of their annual compensation on an
after-tax basis to the retirement plan. "Highly Compensated Employees," as
defined in the retirement plan, are subject to certain other provisions
regarding the amount of eligible contributions. Employee contributions may begin
from the date of hire and are immediately vested. Currently, we do not make
matching or profit-sharing contributions to the retirement plan.

shares, for an aggregate of 145,500 shares. The three series of options provide
for exercise prices of $1.1296, $1.2477 and $1.4238 per share, respectively.
One-third of each option series is fully vested and exercisable and another
one-third of each series will vest on each of October 29, 2000 and October 29,
2001. In addition, upon Mr. Stull's death or disability he shall be vested in a

since the previous October 29. If Mr. Stull should terminate his employment for
cause, as defined in the employment agreement, he shall be vested in the portion
of the series options that would have vested on the October 29 immediately
following such termination. If we terminate Mr. Stull's employment for other
than cause or nonperformance, both as defined in the employment agreement, all
of the options in each series not previously vested shall be immediately vested,
and if we terminate his employment for cause all of his previously unexercised
options in each series, regardless of whether or not previously vested, shall be
forfeited. All vested options not exercised by December 31, 2006, shall be
canceled.

COMPENSATION OF DIRECTORS

    Currently, we do not compensate our directors. No director who is also our
employee receives separate compensation for services rendered as a director.
Starting in June 1999, we had an arrangement with Hicks & Ragland, now known as
CHR Solutions, to pay $175 per hour for Mr. Sharbutt's services as Chairman of
our board of directors. This arrangement with Hicks & Ragland ended on October
1, 1999, when Mr. Sharbutt became our Chief Executive Officer.

    Pursuant to the 1999 Long-Term Incentive Plan, each of our current directors
who is an independent director because he or she is not also our officer or
employee has received an initial option to purchase 28,000 shares of our common
stock. We granted an option to purchase an additional 15,000 shares of our
common stock to Mr. Clapp for his performance of additional duties as director
with respect to our initial public offering and our debt offering. These initial
options became exercisable with respect to 100% of the shares covered thereby
upon consummation of our initial public offering. Directors joining us now,
after our initial public offering, will automatically receive an initial option
to purchase 28,000 shares of our common stock on the date he or she becomes one
of our directors. All initial options will expire on the tenth anniversary of
the date of grant. In addition to the initial option, each independent director
will receive a grant pursuant to our 1999 Long-Term Incentive Plan of an annual
option to purchase that number of shares of our common stock equal to $60,000
divided by the fair market value of our common stock on the date of grant. The
annual option will be automatically granted on the date of the first full
meeting of our board of directors following the end of each fiscal year. The
annual option will immediately vest on the date of grant and will expire on the
tenth anniversary of the date of grant. The exercise price of all options
granted to independent directors must be equal to the fair market value of our
common stock on the date of grant. Directors who are also our officers or
employees receive no additional compensation for serving as directors. All of
our directors are entitled to reimbursement of their reasonable out-of-pocket
expenses in connection with their travel to, and attendance at, meetings of the
board of directors or committees thereof.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    The compensation committee of our board of directors currently consists of
Messrs. Silber, Marshall and Hyde. None of these committee members are or have
been executive officers of us or our subsidiaries. From our inception on July
16, 1998 through December 9, 1999, our board of directors determined the
compensation of our executive officers. David Sharbutt, our Chief Executive
Officer, is Chairman of our board of directors. He is also employed as a Senior
Consultant and is a director and shareholder of CHR Solutions, an engineering
consulting firm that provides services to us. See "Item 13. Certain
Relationships and Related Transactions" for more details regarding these
transactions. Mr. Sharbutt has also served on the board of directors of Alamo
Cellular, Inc. Currently Scotty Hart is Secretary of Alamo Cellular, Inc. and
Jimmy White is President of Alamo Cellular, Inc. Both Mr. Hart and Mr. White are
also on our board of directors. In addition, Alamo IV LLC, prior to its
dissolution in November 1999, had been controlled by its members. Mr. Sharbutt
represented a company called Harlamo LLC, prior to its dissolution in November
1999 that was a member of Alamo IV LLC and he also served as Vice President of
Alamo IV LLC. Thomas Hyde, who is one of our directors, along with Scotty Hart
and Jimmy White, served as executive officers of Alamo IV LLC.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

    Our full board of directors addressed all matters concerning executive
compensation until December 9, 1999, when we formed an executive compensation
committee consisting of Messrs. Silber, Marshall and Hyde. Since its formation,
the compensation committee has addressed executive compensation matters.

    Our executive compensation philosophy reflects our belief that the
compensation of executives should:

     o    be linked to achievement of our business and strategic goals;

     o    be aligned with the interests of stockholders through awards of stock
          options and other stock-based compensation;

     o    recognize individual contributions, as well as overall business
          results; and

     o    result in attracting, motivating and retaining highly-talented
          executives to serve us.

To achieve these objectives, our current compensation program consists of the
following elements:

     o    base salary;

     o    annual incentive compensation, the receipt of which is based on:

     o    our financial performance from year to year; and/or

     o    significant individual contributions; and

     o    long-term incentive compensation, primarily in the form of stock
          options.

Jerry Brantley, as Chief Operating Officer, acted in a capacity similar to that
of chief executive officer during the period from the inception of Alamosa, July
16, 1998, to October 1, 1999, when David Sharbutt was elected Chief Executive
Officer. Mr. Sharbutt has served as our chief executive officer since that time.
The structure of Mr. Brantley's fiscal 1999 compensation was based in part on
comparisons to the compensation of executives in similar positions with other
companies in the industry, as well as Mr. Brantley's level of responsibility,
experience and contribution to our business objectives and the board's ongoing
assessment of our operations. In accordance with such factors, we entered into
an amended and restated employment agreement with Mr. Brantley, effective
October 1, 1999. This agreement provides for a base salary of $175,000, subject
to increases at our board's discretion. In addition, the agreement provides that
Mr. Brantley is eligible for quarterly bonuses upon the achievement of certain
performance targets established by our board, and grants Mr. Brantley stock
options that vest over three years. See "-- Employment Agreements -- Jerry W.
Brantley." Pursuant to this employment agreement, Mr. Brantley received
compensation totaling $324,509 for fiscal 1999, representing a salary of
$175,000, a bonus of $142,309 and a car allowance of $7,200. Our board believes
that the structure of Mr. Brantley's compensation, with its emphasis on our
performance, is in the best interest of our stockholders because it more closely
aligns the interests of Mr. Brantley and our stockholders.

    The structure of Mr. Sharbutt's fiscal 1999 compensation was also based in
part on comparisons to the compensation of executives in similar positions with
other companies in the industry, as well as Mr. Sharbutt's level of
responsibility, experience and contribution to our business objectives and the
board's ongoing assessment of our operations. In accordance with such factors,
we entered into an employment agreement with Mr. Sharbutt, effective October 1,
1999. This agreement provides for a base salary of $175,000, subject to
increases at our board's discretion. In addition, the agreement provides that
Mr. Sharbutt is eligible for quarterly bonuses upon the achievement of certain
performance targets established by our board. See "-- Employment Agreements --
David E. Sharbutt." Pursuant to this employment agreement, Mr. Sharbutt received
compensation totaling $91,250 for fiscal 1999, representing a salary of $43,750,
a bonus of $43,750 and a car/club dues allowance of $3,750. Our board believes
that the structure of Mr. Sharbutt's compensation, with its emphasis on our
performance, is in the best interest of our stockholders because it more closely
aligns the interests of Mr. Sharbutt and our stockholders.

    Other than Mr. Brantley as Chief Operating Officer and Mr. Sharbutt as Chief
Executive Officer, W. Don Stull, as Chief Technology Officer, also received
substantial compensation during fiscal 1999. Our philosophy for the compensation
of our executive officers focuses on each individual's level of responsibility,
experience and contribution to our business objectives and the board's ongoing
assessment of our operations. The board places emphasis on compensation that
closely aligns the executive's interests with the stockholders' interests.
Therefore, a significant percentage of each executive officer's total
compensation is tied to our performance through:

     o    bonus eligibility, based on a combination of our performance and
          individual achievement; and

     o    stock option awards.

     In August 1993, as part of the Omnibus Budget Reconciliation Act of 1993,
Section 162(m) of the Internal Revenue Code was enacted, which section provides
for an annual one million dollar limitation on the deduction that an employer
may claim for compensation of certain executives. Section 162(m) of the Internal
Revenue Code provides an exception to the deduction limitation for certain
performance-based compensation, and it is the intent of the board to qualify
executive compensation for such exception to the extent necessary, feasible and
in our best interests.

     ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

FORMATION OF ALAMOSA PCS, LLC

    On July 24, 1998, Alamo IV LLC, Rosewood Telecommunications, L.L.C., Tregan
International Corp., West Texas PCS, LLC and Longmont PCS, LLC formed Alamosa
PCS, LLC. Those investors received membership interests in exchange for their
capital commitments. The investors amended the formation documents on December
11, 1998 to allow for a new member, Yellow Rock PCS, L.P., and to modify their
membership interests and capital commitments. Yellow Rock agreed to contribute a
total of $400,000 of capital in exchange for a 0.82% membership interest in us.
Pursuant to the agreement, Yellow Rock committed to a funding schedule beginning
with a payment of $123,711 on December 15, 1998 and ending on January 1, 2001.
The original investors retained the remaining 99.18% membership interest in us
in exchange for their capital commitments of $48,100,000. In November 1999, the
members of Alamo IV LLC dissolved Alamo IV LLC and distributed Alamo IV's
membership interest in Alamosa PCS, LLC to Alamo IV's members.

    The obligations to commit capital and the other regulations under the
formation documents were eliminated when we reorganized from a limited liability
company to a holding company structure prior to the closing of our initial
public offering.

NORTEL CREDIT AGREEMENT GUARANTIES

     In connection with our credit agreement with Nortel, each of our
stockholders pledged its ownership interest in Alamosa to Nortel to guaranty our
obligations under the credit agreement. Our stockholders were required to secure
their unfunded contributions with either a letter of credit or a marketable
securities pledge agreement. Each guaranty, pledge, letter of credit and
marketable securities pledge agreement terminated prior to the closing of our
initial public offering.

AGREEMENTS WITH CHR SOLUTIONS

     We have entered into a number of arrangements with CHR Solutions as
described in more detail below. David Sharbutt, our Chairman and Chief Executive
Officer, was at the time the agreements were executed the President, Chief
Executive Officer, a director and a shareholder of CHR Solutions. Mr. Sharbutt
is currently employed as a Senior Consultant by CHR Solutions.

     o    On July 27, 1998, we entered into an engineering service contract with
          CHR Solutions that is to last through August 2001 for a maximum fee of
          approximately $7.0 million, excluding taxes. We paid $902,243 in 1998

     o    On November 20, 1998, we entered into a special service contract
          effective as of September 20, 1998 with CHR Solutions, who provided us

          telecommunications lines between Sprint PCS and our Lubbock operations
          and between our Lubbock operations and our other markets. The original
          term of the agreement is three years, with automatic renewal for

          agreement lasts until the project is completed, unless either party
          terminates it earlier for cause.

          Alamosa and other third party distributors, under which TechTel
          Communications Corporation is obligated to purchase ten handsets from
          us every quarter for the term of one year.

AGREEMENT WITH AMERICAN TOWER CORPORATION

    In August 1998, we entered into a master site development and lease
agreement with Specialty, a subsidiary of Specialty Teleconstructors, Inc. that
has since merged with American Tower Corporation. Pursuant to the agreement,
Specialty arranges for collocation of our equipment, or constructs new
facilities, in areas we identify for build-out. The initial term of this lease

years each. The agreement provides for monthly payments aggregating to
approximately $5 million a year, subject to an annual adjustment based on the
Consumer Price Index. Michael Budagher, who is one of our directors and a
manager of West Texas PCS, LLC, one of our stockholders, was, at the time the

director of Specialty Teleconstructors, Inc., and the Chief Executive Officer,
President and sole director of Specialty. Michael Budagher is also a member and
the General Manager of the Budagher Family LLC, which was, at the time the
agreement was entered into, a stockholder of Specialty Teleconstructors, Inc.
Mr. Budagher no longer holds any of these positions at Specialty or Specialty
Teleconstructors, Inc. and the Budagher Family LLC is no longer a stockholder of
Specialty Teleconstructors, Inc. Additionally, Jeff Howard, who was one of our
directors at the time the agreement was entered into, is a manager of Longmont
PCS, LLC, one of our stockholders, is a stockholder of Specialty
Teleconstructors, Inc. and acts as a Vice President of American Tower
Corporation though he has not been designated as an officer by American Tower
Corporation's board of directors and has no management authority.

RESERVE OF SHARES BY UNDERWRITERS

    As part of the initial public offering of our common stock, the underwriters
reserved a maximum of 10% of the shares of our common stock sold in the offering
for sale to our current stockholders at a price per share of $15.8525, the
public offering price less the underwriting discount. The underwriters were not
entitled to any discount or commission on these shares and the proceeds to us
were the same as if the shares were sold to the general public. Current
stockholders purchased 757,589 shares pursuant to this arrangement.

    In connection with our initial public offering, Salomon Smith Barney Inc.
reserved up to approximately five percent of the shares being offered as
directed shares for sale at the initial public offering price to persons who are
directors, officers or our employees, or who are otherwise associated with us
and our affiliates or employees, and who have advised us of their desire to
purchase these shares. The number of shares of common stock available for sale
to the general public was reduced to the extent of sales of directed shares to
any of the persons for whom they have been reserved. A total of 535,000 shares
of common stock were so purchased by such persons.

OTHER RELATED PARTY TRANSACTIONS

    On April 23, 1999, we entered into a $100,000 loan agreement with one of our

optional five-year terms. The lease provides for monthly payments aggregating to

                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and
Stockholders of Alamosa PCS Holdings, Inc.

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, stockholders' equity and cash flows
present fairly, in all material respects, the financial position of Alamosa PCS
Holdings, Inc. (a development stage enterprise) and its subsidiaries at December
31, 1999 and December 31, 1998, and the results of their operations and their
cash flows for the year ended December 31, 1999, the period from July 16, 1998
(inception) through December 31, 1998, and the period from July 16, 1998
(inception) through December 31, 1999, in conformity with accounting principles
generally accepted in the United States. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with auditing standards generally
accepted in the United States which require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                          NOTES TO FINANCIAL STATEMENTS


1.   ORGANIZATION AND BUSINESS OPERATIONS

     Alamosa PCS Holdings Inc. ("Holdings") was formed in October 1999 in
     anticipation of an initial public offering as described in Note 14.
     Immediately prior to the offering in February 2000, shares of Holdings, the
     registrant, were exchanged for Alamosa PCS LLC's ("Alamosa") membership
     interests, and Alamosa became wholly owned by Holdings. These financial
     statements are presented as if the reorganization had occurred as of the
     beginning of the periods presented. There were no activities within
     Holdings prior to the reorganization. Holdings and its subsidiaries,
     including Alamosa, are collectively referred to in these financial
     statements as the "Company." Other subsidiaries formed include Texas
     Telecommunications LP ("Texas") and Alamosa Wisconsin Limited Partnership
     ("Wisconsin").

     Alamosa and its successor Alamosa PCS, Inc., referred to in these financial
     statements as Alamosa, was formed in July 1998 as a Texas limited liability
     company. In July 1998, Alamosa entered into affiliation agreements with
     Sprint PCS, the PCS Group of Sprint Corporation. These affiliation
     agreements provided Alamosa with the exclusive right to build, own and
     manage a wireless voice and data services network in markets with over 5.2
     million residents located in Texas, New Mexico, Arizona and Colorado under
     the Sprint PCS brand. Alamosa amended its affiliation agreements with
     Sprint PCS in December 1999 to expand its services network so that it will
     include 8.4 million residents. Alamosa is required to build out the
     wireless network according to Sprint PCS specifications. The affiliation
     agreements are in effect for a term of 20 years with three 10-year renewal
     options unless terminated by either party under provisions outlined in the
     affiliation agreements. The affiliation agreements include indemnification
     clauses between Alamosa and Sprint PCS to indemnify each other against
     claims arising from violations of laws or the affiliation agreements, other
     than liabilities resulting from negligence or willful misconduct of the
     party seeking to be indemnified.

     Holdings and Alamosa are currently in the development stage. This stage is
     characterized by significant expenditures for the design and construction
     of the wireless network. Management estimates total network build-out
     expenditures related to the markets included in the affiliation agreements
     with Sprint PCS of approximately $272 million, including site acquisition,
     design, construction and equipment through 2002. These expenditures will be
     funded through member contributions of $37 million, a financing agreement
     with Nortel Networks, Inc. ("Nortel") of $250 million and proceeds of the
     initial public offering and Senior Discount Notes proceeds described in
     Note 14. From inception through December 31, 1999, the Company has
     commenced operations in eleven markets. Since inception, the Company has
     incurred revenues and expenses of $8,983,713 and $42,743,394 resulting in a
     deficit accumulated during the development stage of $33,759,681 at December
     31, 1999. Alamosa has signed an agreement with a related party for the
     provision of engineering services related to the network build-out. Once
     the initial build-out is completed within a market, the Company's focus is
     the development of the Sprint PCS subscriber base within that market.

     Prior to the reorganization discussed above, the Regulations of Alamosa, as
     amended, provided for the governance and administration of its business,
     allocation of profits and losses, tax allocations, transactions with
     partners, disposition of ownership interest and other matters. The
     Regulations established two classes of membership interests. Class I
     members had full voting rights and were entitled to full benefits of
     ownership of their share of Alamosa. Class II members consisted of
     additional non-voting share interests of Alamosa, which the Board of
     Managers may authorize to be distributed to employees of Alamosa under an
     incentive bonus plan. The Regulations generally provided for the allocation
     of profits and losses pro-rata based on the proportion that a percentage
     interest of a member bears to the aggregate percentage interests of all
     members, as defined in the Regulations.

     Alamo IV, LLC was dissolved in November 1999. Upon the dissolution, its
     members received their pro rata portions of ownership interest of Alamosa
     PCS LLC. In conjunction with the reorganization described above, the
     ownership interests of Alamosa PCS LLC were exchanged for an equivalent
     interest in Holdings' common stock.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Cash and cash equivalents - Cash and cash equivalents include cash, money
     market funds, and commercial paper with minimal interest rate risk and
     original maturities of three months or less at the date of acquisition. The
     carrying amount approximates fair value.

     Property and equipment - Property and equipment are reported at cost less
     accumulated depreciation. Cost incurred to design and construct the
     wireless network in a market are classified as construction in progress.
     When the wireless network for a particular market is completed and placed
     into service, the related costs are transferred from construction in
     progress to property and equipment. Repair and maintenance costs are
     charged to expense as incurred; significant renewals and betterments are
     capitalized. When depreciable assets are retired or otherwise disposed of,
     the related costs and accumulated depreciation are removed from the
     respective accounts, and any gains or losses on disposition are recognized
     in income. If facts or circumstances support the possibility of impairment,
     the Company will prepare a projection of future operating cash flows,
     undiscounted and without interest. If based on this projection, the Company
     does not expect to recover its carrying cost, an impairment loss equal to
     the difference between the fair value of the asset and its carrying value
     will be recognized in operating income. No such losses have been recognized
     to date.

     Property and equipment are depreciated using the straight-line method based
     on estimated useful lives of the assets.

     Asset lives are as follows:

                   NOTES TO FINANCIAL STATEMENTS - (CONTINUED)


     Interest will be capitalized in connection with the construction of the
     wireless network. The capitalized interest will be recorded as part of the
     asset to which it relates and will be amortized over the asset's estimated
     useful life. Total interest capitalized is $656,985 as of December 31,
     1999. No interest was capitalized in 1998.

     Microwave relocation includes costs and the related obligation incurred to
     relocate incumbent microwave frequencies in Alamosa's service area.
     Microwave relocation costs are amortized on a straight-line basis over 20
     years beginning upon commencement of services in respective markets. The
     amortization of microwave relocation costs was $84,312 for the year ended
     December 31, 1999.

     Software costs - Initial operating systems software is capitalized and
     amortized using the straight-line method, generally over a period of five
     years. Capitalized software of approximately $411,000 and $11,500 at
     December 31, 1999 and 1998, respectively, are recorded in property and
     equipment. The Company amortized computer software costs of approximately
     $40,000 and $1,000 during 1999 and 1998, respectively.

     Start-up costs - In April 1998, the American Institute of Certified Public
     Accountants ("AICPA") issued Statement of Position ("SOP") 98-5, "Reporting
     on the Costs of Start-Up Activities." This statement became effective
     January 1, 1999 and required that costs of start up activities and
     organization costs be expensed as incurred.

     Advertising costs - Advertising costs are expensed as incurred. Advertising
     expenses totaled approximately $7,300,925 and $2,000 during 1999 and 1998,
     respectively. Advertising costs include handset subsidy expenses
     representing the excess of the cost of handsets over the retail sales
     price. Handset subsidy expense was $5,023,430 for the year ended December
     31, 1999. There was no handset subsidy expense during 1998.

     Income taxes - At December 31, 1999 and 1998, Alamosa was organized as a
     Texas limited liability company. Therefore, the taxable loss of the Company
     was included in the income tax returns of its members. While no benefit for
     income taxes was recorded in the financial statements of Alamosa, the
     statements of operations includes proforma information as if Alamosa was a
     taxable entity as described in Note 3.

     Revenue recognition - The Company recognizes revenue as services are
     performed. Sprint PCS handles Alamosa's billings and collections and
     retains 8% of collected service revenues from Sprint PCS subscribers based
     in Alamosa's territory and from non-Sprint PCS subscribers who roam onto
     Alamosa's network. The amount retained by Sprint PCS is recorded in Cost of
     Service and Operations. Revenues generated from the sale of handsets and
     accessories and from roaming services provided to Sprint PCS customers who
     are not based in Alamosa's territory are not subject to the 8% retainage.

     Sprint PCS pays Alamosa a Sprint PCS roaming fee for each minute that a
     Sprint PCS subscriber based outside of Alamosa's territory roams on
     Alamosa's portion of the Sprint PCS network. Revenue from these services
     will be recognized as the services are performed. Similarly, Alamosa will
     pay Sprint PCS roaming fees to Sprint PCS, when a Sprint PCS subscriber
     based in Alamosa's territory roams on the Sprint PCS network outside of
     Alamosa's territory. These costs will be included as cost of service when
     incurred.

     Product revenues consisting of proceeds from sales of handsets and
     accessories are recorded net of an allowance for sales returns. The
     allowance is estimated based on Sprint PCS's handset return policy that
     allows customers to return handsets for a full refund within 30 days of
     purchase. When handsets are returned to the Company, the Company may be
     able to reissue the handsets to customers at little additional cost.
     However, when handsets are returned to Sprint PCS for refurbishing, the
     Company will receive a credit from Sprint PCS, which will be less than the
     amount the Company originally paid for the handset. For the year ended
     December 31, 1999 product revenue was $2,450,090. The cost of these
     products was $7,426,736, of which $2,403,306 has been classified as cost of
     products sold and $5,023,430 represents the excess of the cost of handsets
     over the retail sales price of handsets has been included in advertising
     costs. The basis for inclusion of the excess handset cost in advertising
     expense is to reflect the promotional nature of these

     transactions. Alamosa sells handsets solely as a means to attract wireless
     subscribers. There were no product revenues or related costs for the period
     from inception to December 31, 1998.

     Stock based compensation - The Company has elected to follow Accounting
     Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued to
     Employees" and related interpretations in accounting for its employee stock
     options. The non-cash compensation expense relates to three employees whose
     cash compensation is recorded in cost of service and operations and general
     and administrative expenses. The Company has implemented the
     disclosure-only provisions of Statement of Financial Accounting Standards
     ("SFAS") No. 123, "Accounting for Stock Based Compensation."

     Use of estimates - The preparation of financial statements in conformity
     with generally accepted accounting principles requires management to make
     estimates and assumptions that affect the reported amounts of assets and
     liabilities and disclosure of contingent assets and liabilities on the date
     of the financial statements and the reported amounts of expenses during the
     reporting period. Actual results could differ from those estimates.

     Risks and uncertainties - Emergence from the development stage is dependent
     upon successful implementation of the Company's business strategy and
     development of a sufficient subscriber base. The Company will continue to
     incur significant expenditures in connection with expanding and improving
     its operations.

     Concentration of risk - The Company maintains cash and cash equivalents in
     accounts with a financial institution in excess of the amount insured by
     the Federal Deposit Insurance Corporation. The Company monitors the
     financial stability of this institution regularly and management does not
     believe there is significant credit risk associated with deposits in excess
     of federally insured amounts.

     Reclassification - Certain reclassifications have been made to prior year
     balances to conform to current year presentations.

     Effects of recent accounting pronouncements - In June 1998 and June 1999,
     the Financial Accounting Standards Board ("FASB"), issued SFAS No. 133,
     "Accounting for Derivative Instruments and Hedging Activities" and SFAS No.
     137, "Accounting for Derivative Instruments and Hedging Activities-Deferral
     of the Effective Date of FASB Statement No. 133." These statements require
     companies to record derivatives on the balance sheet as assets or
     liabilities, measured at fair value. Gains or losses resulting from changes
     in the values of those derivatives would be accounted for depending on the
     use of the derivative and whether it qualifies for hedging accounting. SFAS
     No. 133 will be effective for Alamosa's fiscal year ending December 31,
     2001. Management believes that the adoption of these statements will not
     have a significant impact on the Company's financial results.

     In June 1997, FASB issued SFAS No. 130, "Reporting Comprehensive Income."
     This statement requires that all items required to be recognized under
     accounting standards as components of comprehensive income be reported in a
     financial statement that is displayed with the same prominence as other
     financial statements. SFAS No. 130 is effective for financial statement
     periods beginning after December 31, 1997. No items represent comprehensive
     income as defined in SFAS No. 130 during 1999 and 1998.

     In December 1999, the Securities and Exchange Commission issued Staff
     Accounting Bulletin No. 101 ("SAB101"), "Revenue Recognition in Financial
     Statements." SAB101 summarizes certain of the staff's interpretations in
     applying generally accepted accounting principles to revenue recognition.
     The provisions of SAB101 are effective for Alamosa's quarter ending March
     31, 2000. Management is currently assessing the impact of the adoption of
     SAB101.

3.   UNAUDITED PRO FORMA INFORMATION

     The unaudited pro forma information reflects certain assumptions regarding
     transactions and their effects that occurred as a result of the
     reorganization described in Note 1.

                   NOTES TO FINANCIAL STATEMENTS - (CONTINUED)

     Unaudited pro forma income information - The unaudited pro forma
     information as shown on the statements of operations is presented to show
     the effects of income taxes related to the Company's subsequent termination
     of its limited liability company status. The unaudited pro forma income tax
     adjustment is presented as if the Company had been a C Corporation subject
     to federal and state income taxes at an effective tax rate of 34% for the
     period from inception through December 31, 1998 and the year ended December
     31, 1999. Application of the provisions of SFAS No. 109, "Accounting for
     Income Taxes" would have resulted in a deferred tax asset primarily from
     temporary differences related to the treatment of start-up costs and from
     net operating loss carryforwards. The deferred tax asset would have been
     offset by a full valuation allowance, as there is not currently sufficient
     positive evidence as required by SFAS No. 109 to substantiate recognition
     of the asset.

     The pro forma information is presented for informational purposes only and
     is not necessarily indicative of operating results that would have occurred
     had the Company elected to terminate its limited liability company status
     as of the beginning of each of the periods presented, nor are they
     necessarily indicative of future operating results.

     Unaudited pro forma net loss per share - Pro forma net loss per share is
     calculated by dividing pro forma net loss by the weighted average number of
     shares of common stock which would have been outstanding before the initial
     public offering after giving effect to the reorganization of the Company
     described in Note 1.

     Unaudited pro forma weighted average shares outstanding - Unaudited pro
     forma weighted average shares outstanding is computed after giving effect
     to the reorganization of the Company described in Note 1. The calculation
     was made in accordance with SFAS No. 128, "Earnings Per Share." Diluted
     weighted average shares outstanding at December 31, 1999 exclude 141,042
     incremental potential common shares from stock options because inclusion
     would have been antidilutive.

                   NOTES TO FINANCIAL STATEMENTS - (CONTINUED)


7.   LONG-TERM DEBT

     Long-term debt at December 31, 1999 included $71,876,379 owed to Nortel and
     $50,035 owed to another party relating to the build-out of retail
     facilities.

     On February 3, 1999, Alamosa issued a $7,500,000 letter of credit in favor
     of Nortel. The letter of credit expired in June 1999. On June 10, 1999,
     Alamosa entered into a credit agreement with Nortel. The proceeds of that
     credit facility are used to purchase equipment, to fund the construction of
     the Company's portion of the Sprint PCS network, and to pay associated
     financing costs. The financing terms permit Alamosa to borrow $123 million
     under three commitment tranches through February 18, 2002, and will require
     minimum equipment purchases.

     The Nortel credit facility is collateralized by all of Alamosa's current
     and future assets and capital stock. Alamosa is required to maintain
     certain financial ratios and other financial conditions including minimum
     levels of revenue and wireless subscribers. In addition, Alamosa is
     required to maintain a $1,000,000 cash balance as collateral against the
     facility. At December 31, 1999, Alamosa was not in compliance with this
     agreement; however, a waiver of this requirement was obtained from Nortel.

     In connection with the credit agreement with Nortel, each of the former
     members of Alamosa pledged its ownership interest in Alamosa to Nortel to
     collateralize Alamosa's obligations under the credit agreement. The members
     secured their unfunded contributions with either a letter of credit or a
     marketable securities pledge agreement. Each letter of credit or marketable
     securities pledge agreement will be terminated prior to the closing of the
     initial public offering described in Note 14. In addition, Nortel required
     the members to execute capital contribution agreements to confirm their
     collective obligations to make capital contributions of at least $48.5
     million.

     Alamosa may borrow money under the Nortel credit facility as either a base
     rate loan with an interest rate of prime plus 2.5%, or a Eurodollar loan
     with an interest rate of the London interbank offered rate, commonly
     referred to as LIBOR, plus 3.75%. The LIBOR was 9.5% at December 31, 1999.
     In addition, an annual unused facility fee of 0.75% will be charged
     beginning six months after the closing date on the portion of the available
     credit that has not been borrowed. Interest accrued through the two-year
     anniversary from the closing date is added to the principal amount of the
     loan. Thereafter, interest is payable monthly in the case of base rate
     loans and at the end of the applicable interest period, not to exceed three
     months, in the case of Eurodollar loans. Interest expense for the year
     ended December 31, 1999 totaled $2,068,601. Principal is payable in 20
     quarterly installments beginning February 18, 2002. Alamosa may voluntarily
     prepay any of the loans at any time, but any amount repaid may not be
     reborrowed since there are no revolving credit features. Alamosa must make
     mandatory prepayments under certain circumstances, including 50% of the
     excess cash flow, as computed under the credit agreement, after March 31,
     2002 and any amount in excess of $250,000 received for asset sales outside
     the ordinary course of business or insurance proceeds, to the extent not
     reinvested in property or assets within a stated period of time. All
     prepayments are applied to the outstanding loan balances pro rata in the
     inverse order of maturity, except where there is a borrowing base shortage,
     in which case prepayments are first applied there, and then pro rata among
     all three commitment tranches.

     As a condition of the financing, Sprint PCS has entered into a consent and
     agreement with Nortel that modifies Sprint PCS's rights and remedies under
     its affiliation agreements with Alamosa. Among other things, Sprint PCS
     consented to the pledge of substantially all of Alamosa's assets to Nortel,
     including the affiliation agreements. In addition, Sprint PCS may not
     terminate the affiliation agreements with Alamosa and must maintain 10 MHz
     of PCS spectrum in Alamosa's markets until the Nortel financing is
     satisfied or Alamosa's assets are sold pursuant to the terms of the consent
     and agreement with Nortel.

     Alamosa incurred approximately $4,074,000 of costs associated with
     obtaining the Nortel financing. Those costs consisted of a loan origination
     fee, legal fees and other debt issue costs that have been capitalized and
     are being amortized to interest expense using the straight-line method over
     the term of the credit facility.

8.   RELATED PARTY TRANSACTIONS

     Note receivable - On April 23, 1999, the Company entered into a $100,000
     loan agreement with an officer of the Company. The loan matures on April
     2014 and accrues interest at an annual rate of 7.75%.

     Agreements with CHR Solutions, Inc. - Alamosa has entered into a number of
     agreements with CHR Solutions, Inc. ("CHR") as described in more detail
     below. CHR resulted from a merger between Hicks & Ragland Engineering Co.,
     Inc., and Cathey, Hutton & Associates, Inc. effective as of November 1,
     1999. David Sharbutt, Alamosa's Chairman and Chief Executive Officer, was
     at the time the agreements were executed the President and Chief Executive
     Officer of Hicks & Ragland. Mr. Sharbutt is currently employed as a senior
     consultant by CHR Solutions.

     On July 27, 1998, Alamosa entered into an engineering services contract
     with CHR for design and construction inspection services in connection with
     the network deployment. The term of the contract covers three periods
     through August 2001, though either party may terminate the agreement for
     cause before August 2001. A guaranteed maximum fee amount has been set for
     each period of the contract, and those fees aggregate to approximately $7.0
     million, excluding taxes. If the total billing for the project is less than
     the guaranteed maximum fee, Alamosa will pay an incentive bonus equal to
     50% of the difference. Alamosa paid $2,951,476 and $902,243 for these
     services during 1999 and 1998, respectively. Engineering fees under this
     agreement are recorded in construction in progress and property and
     equipment and comprise approximately 4% and 72% of fixed asset purchases
     during 1999 and 1998, respectively. At December 31, 1999 and 1998, amounts
     payable under these agreements amounted to $709,987 and $443,610,
     respectively.

     Effective September 20, 1998, Alamosa entered into a special services
     contract with CHR to provide marketing and operations consulting services
     for a maximum amount of $100,000. Subsequent contracts for marketing,
     consulting, business planning and radio frequency "drive testing" were
     approved in October 1999, in an aggregate amount of approximately $500,000.
     Alamosa paid $424,994 for these services for the year ended December 31,
     1999. The amounts payable under these agreements was $139,822 at December
     31, 1999.

     On April 9, 1999, Alamosa entered into a data communications services
     contract with CHR to perform design and implementation services in
     connection with corporate enterprise wide area network and local area
     networks for a maximum fee of $262,040. Alamosa paid $88,486 for these
     services for the year ended December 31, 1999. The amount payable under
     this agreement amounted to $20,132 at December 31, 1999.

     As of April 6, 1999, Alamosa entered into a telecommunications service
     agreement with Tech Telephone Company Limited Partnership, an affiliate of
     CHR, to install and provide DS1 telecommunications lines between Sprint PCS
     and Alamosa's Lubbock-based operations and between Alamosa's Lubbock-based
     operations and other markets. The original term of the agreement is three
     years, but the agreement automatically renews upon expiration for
     additional successive 30-day terms by either party. Transport expenses
     under the agreement amounted to $346,740 for 1999 and are included in Cost
     of Service and Operations.

     As of August 13, 1999, Alamosa entered into a distribution agreement with
     TechTel Communications Corporation, an affiliate of CHR, authorizing it to
     become a third party distributor of Sprint PCS products and services for
     Alamosa in Lubbock.

     As of October 8, 1999, we entered into a special service contract with CHR
     to perform marketing and operations consulting services in selected areas
     in Wisconsin for a maximum fee of $100,000, excluding taxes. This agreement
     lasts until the project is completed, unless either party terminates it
     earlier.

     As of October 8, 1999, we entered into a special service contract with CHR
     to perform business planning and consulting services and a feasibility

     Agreement with American Tower Corporation - In August 1998, Alamosa entered
     into a master site development and lease agreement with Specialty Capital
     Services, Inc. ("Specialty"), a subsidiary of Specialty Teleconstructors,
     Inc. ("Teleconstructors"), that has since merged with American Tower
     Corporation ("American"). Pursuant to the agreement, Specialty arranges for
     collocation of equipment or constructs new facilities in areas identified
     for build-out. Specialty provides site acquisitions, leasing and
     construction services, and secures zoning, permitting and surveying
     approvals and licenses for each base station. This initial term master
     agreement expires in August 2003, with automatic renewal for three
     additional terms of five years each. The agreement provides for monthly
     payments subject to an annual adjustment based on the Consumer Price Index.
     Prior to October 1, 1999, Specialty was related to Alamosa through one of
     Alamosa's directors who owned interests in both Alamosa and
     Teleconstructors and was an employee and officer of Specialty and
     Teleconstructors. In addition, another individual who was one of Alamosa's
     directors at the time the agreement was entered into is a manager of
     Longmont PCS, LLC, one of Alamosa's former members. This individual was
     also a stockholder of Teleconstructors and acted as a vice president of
     American, which acquired Teleconstructors. The two individuals completed
     the disposition of their ownership interests in American by September 30,
     1999 and are no longer associated with American. No amounts were paid or
     outstanding under this agreement during 1998. Through September 30, 1999,
     $165,300 was paid under this agreement.

     Other related party transactions - In November 1998, the Company entered
     into an agreement to lease space for telephone switching equipment in
     Albuquerque with SASR Limited Partnership, 50% owned by one of Alamosa's
     directors and a manager of West Texas PCS, LLC, and Budagher Family LLC,
     two of Alamosa's interest holders. The lease has a term of five years with
     two optional five-year terms. The lease provides for monthly payments
     aggregating to $18,720 a year with 10% increase at the beginning of the two
     option periods, as well as a pro rata portion of real estate taxes on the
     property.

     In connection with Alamosa's distribution and sales of Sprint PCS wireless
     communications equipment, on December 28, 1998, Alamosa entered into a
     long-term agreement to lease space for a retail store in Lubbock, Texas
     with Lubbock HLH, Ltd., principally owned by one of Holding's directors and
     the general manager of South Plains Advance Communications & Electronics,
     Inc. ("SPACE"). SPACE is a stockholder of Alamosa. This lease has a term of
     15 years and provides for monthly payments aggregating to approximately
     $110,000 a year, subject to adjustment based on the Consumer Price Index on
     the first day of the sixth lease year and on the first day of the eleventh
     lease year. No amounts were paid or outstanding under this lease at
     December 31, 1998. During 1999, $73,233 was paid under this lease. No
     amount was payable at December 31, 1999.

     During 1998, certain members paid costs on behalf of the Company, which
     were subsequently reimbursed. Such payments amounted to approximately
     $101,000 during 1998 and were minimal during 1999. No amounts payable to
     members were outstanding at December 31, 1999 and 1998.

9.   EMPLOYEE BENEFITS

     Effective November 13, 1998, Alamosa elected to participate in the NTCA
     Savings Plan, a defined contribution employee savings plan sponsored by the
     National Telephone Cooperative Association under Section 401(k) of the
     Internal Revenue Code. No employer contributions were made to this plan for
     the period ended December 13, 1999 and 1998.

     Effective October 1, 1999, Alamosa entered into a three-year employment
     agreement with its Chief Executive Officer ("CEO"), Alamosa's chairman. In
     addition, in December 1999, Alamosa granted options to the CEO to acquire
     242,500 common shares at an exercise price of $1.15 per share which vested
     immediately prior to the completion of the initial public offering and
     1,455,000 shares at an exercise price equal to the initial public offering
     price which vest 33% per year beginning September 30, 2000. The options
     expire January 5, 2009. The Company will recognize compensation expense of
     $3,116,125 related to the 242,500 options issued with an exercise price
     below the initial public offering price over the options vesting period.
     Compensation expense recorded for the year ended December 31, 1999 was
     $351,328.

     On October 2, 1998, Alamosa entered into an employee agreement with its
     Chief Operating Officer ("COO"). The agreement provides for the granting
     of stock options in three series. The initial exercise price was determined
     based on the following formula: $48,500,000, committed capital at September
     30, 1998, multiplied by the percentage interest represented by the option
     exercised. The exercise price for each series increased by an annual rate
     of 8%, 15% or 25% compounded monthly beginning at the date of grant as
     specified by the agreement. Options may be exercised any time from January
     1, 2004 to January 5, 2008. The options vest over a three-year period.
     During 1998, one option from each series was granted under this agreement.
     The options to acquire membership interests described above were to be
     exchanged for options in Holdings to acquire an equivalent number of common
     shares: 242,500 at $1.08 per share, 242,500 at $1.15 per share and 242,500
     at $1.25 per share. Effective December 1999, the Company amended his
     options such that each of his three series of original options were
     exchanged for two options to acquire a total of 1,697,500 shares of common
     stock. The first option to acquire 242,500 shares of common stock has a
     fixed exercise price of $1.15 per share and vested immediately prior to
     completion of the initial public offering. The second option to acquire
     1,455,000 shares of common stock has an exercise price equal to the initial
     public offering price and vests 25% per year beginning September 30, 2000.
     The expiration date of all of the COO's options was extended from January
     5, 2008 to January 5, 2009. These amendments resulted in a new measurement
     date. The Company will record compensation expense totaling $11,523,600 in
     connection with these options. Compensation expense recorded for the year
     ended December 31, 1999 was $6,588,755.

     Effective December 1, 1999, the Company entered into a five-year employment
     agreement with its Chief Financial Officer ("CFO"). In addition, Alamosa
     granted the CFO options to purchase 1,455,000 shares at the initial public
     offering price and that will expire January 5, 2009. There is no
     compensation cost related to these options.

     On October 14, 1998, the Board of Members of Alamosa approved an Incentive
     Ownership Plan. The plan consisted of 3,500 units comprised of 1200 Series
     8, 1150 Series 15 and 1150 Series 25 units. The exercise price for each
     series was based on a pre-defined strike price which increased by an annual
     rate of 8%, 15% or 25% compounded monthly beginning July 1, 2000. The
     initial exercise prices were $564.79, $623.84 and $711.88 for Series 8,
     Series 15 and Series 25 options, respectively. Each unit provided the
     holder an option to purchase an interest in the Company. Vested units could
     have been exercised any time from July 1, 2000 to December 31, 2006. On
     October 29, 1998, under an employment agreement with the Company's Chief
     Technology Officer, 300 units were granted under this plan. The options to
     acquire membership interests described above were to be exchanged for
     options to acquire an equivalent number of common shares: 48,500 at $1.13
     per share, 48,500 at $1.25 per share and 48,500 at $1.42 per share.
     Effective as of the IPO, these options were converted into options of
     Holdings and were amended such that his original options with exercise
     prices that increased by an annual rate of 8%, 15%, or 25% (compounded
     monthly beginning July 1, 2000) were exchanged for options to purchase an
     equivalent number of common shares at fixed exercise prices equal to $1.13,
     $1.25 and $1.42 per share, which will not increase over the term of the
     options. These amendments will resulted in a

     new measurement date. The Company will record compensation expense totaling
     $1,852,651 in connection with these options. Compensation expense recorded
     for the year ended December 31, 1999 was $1,259,427.

10.  STOCK-BASED COMPENSATION

     Holdings adopted an Incentive Stock Option Plan (the "Plan") effective
     November 12, 1999, which provides for the granting of either incentive
     stock options or nonqualified stock options to purchase shares of Holdings'
     common stock and for other stock-based awards to officers, directors and
     key employees for the direction and management of the Company and to
     non-employee consultants and independent contractors. At December 31, 1999,
     7,000,000 shares of common stock were reserved for issuance under the Plan.
     The compensation committee of the board of directors administers the Plan
     and determines grant prices and vesting periods.

     The Company applies APB No. 25, "Accounting for Stock Issued to Employees"
     and related interpretation, in accounting for its employee stock options.
     In accordance with APB No. 25, no compensation expense or unearned
     compensation was recorded as of December 31, 1998. As of December 31, 1999,
     the Company has recorded compensation of $14,309,876. This amount is being
     recognized over the vesting period in accordance with FASB Interpretation
     No. 28 when applicable. For the year ended December 31, 1999, non-cash
     compensation of $8,199,511 has been recognized.

     As discussed in Note 2, the Company has adopted the disclosure-only
     provisions of SFAS No. 123. Had compensation cost for the Company's stock
     option plans been determined based on the fair value provisions of SFAS No.
     123, the Company's net income and net income per share would have been
     decreased to the pro forma amounts indicated below:

     The pro forma disclosures provided are not likely to be representative of
     the effects on reported net income or loss for future years due to future
     grants and the vesting requirements of the Company's stock option plans.

     The weighted-average fair value for options with exercise prices greater
     than the market price issued of the stock at the grant date was $0.46 for
     1998. There were no options issued with exercise prices greater than market
     price at the grant date during 1999. The weighted-average fair value for
     options with exercise prices equal to the market price of the stock at the
     grant date was $9.22 in 1999. There were no options issued with exercise
     prices equal to market price of the stock at grant date during 1998. The
     weighted-average fair value for options with exercise prices below the
     market price of stock at grant date was $13.04 in 1999. There were no
     options issued with exercise prices below the market price at the grant
     date during 1998. The fair value of each option grant is estimated on the
     date of grant using the Black-Scholes option-pricing model with the
     following weighted-average assumptions:

11.  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of cash, accounts payable, and accrued expenses
     approximate fair value because of the short maturity of these items.

     The carrying amount of the debt issued pursuant to the Company's credit
     agreement with Nortel is expected to approximate fair value because the
     interest rate changes with market interest rates.

     Alamosa utilizes interest rate cap agreements to limit the impact of
     increases in interest rates on its floating rate debt. The interest rate
     cap agreements require premium payments to counterparties based upon a
     notional principal amount. Interest rate cap agreements entitle the Company
     to receive from the counterparties the amounts, if any, by which the
     selected market interest rates exceed the strike rates stated in the
     agreements. The fair value of the interest rate cap agreements is estimated
     by obtaining quotes from brokers and represents the cash requirement if the
     existing contracts had been settled at the balance sheet dates.

     Selected information related to the Company's interest rate cap agreements
     is as follows:

     These fair value estimates are subjective in nature and involve
     uncertainties and matters of considerable judgment and therefore, cannot be
     determined with precision. Changes in assumptions could significantly
     affect these estimates.

12.  COMMITMENTS AND CONTINGENCIES

     On December 21, 1998, Alamosa entered into a three-year agreement with
     Nortel to purchase network equipment and infrastructure. Pursuant to that
     agreement, Nortel also agreed to provide installation and optimization
     services, such as network engineering and radio frequency engineering, for
     the equipment and to grant Alamosa a nonexclusive license to use the
     software associated with the Nortel equipment. Alamosa has committed to
     purchase $82.0 million worth of equipment and services from Nortel, which
     Nortel has agreed to finance these purchases pursuant to the Nortel credit
     facility. Under the agreement, Alamosa will receive a discount on the
     network equipment and services because of the Company's affiliation with
     Sprint PCS, but must pay a premium on any equipment and services financed
     by Nortel. If Alamosa's affiliation with Sprint PCS ends, Nortel has the
     right to either terminate the agreement or, with Alamosa's consent, modify
     the agreement to establish new prices, terms and conditions. Alamosa
     entered into a modification of the agreement with Nortel after December 31,
     1999 as described in Note 14.

14.  SUBSEQUENT EVENTS

     Initial Public Offering of Common Stock - On October 29, 1999, Holdings
     filed a registration statement with the Securities and Exchange Commission
     for the sale of 10,714,000 shares of its common stock (the "Stock
     Offering"). The Stock Offering became effective and the shares were issued
     on February 3, 2000 at the initial price of $17.00 per share. Subsequently,
     the underwriters exercised their over-allotment option of 1,607,100 shares.
     Holdings received net proceeds of $194.3 million after commissions of $13.3
     million and expenses of approximately $1.0 million. The proceeds of the
     Stock Offering are to be used for the build out of the system, to fund
     operating working capital needs and for other general corporate purposes.

     Initial Public Offering of Senior Discount Notes - On December 23, 1999,
     Holdings filed a registration statement with the Securities and Exchange
     Commission for the issuance of $350 million face amount of Senior Discount
     Notes (the "Notes Offering"). The Notes Offering was completed on February
     8, 2000 and generated net proceeds of approximately $181 million after
     underwriters' commissions and expenses of approximate $6.1 million. The
     Senior Discount Notes ("Notes") mature in ten years (February 15, 2010) and
     carry a coupon rate of 12 7/8%, and to provide for interest deferral for
     the first five years. The Notes will accrete to their $350 million face
     amount by February 8, 2005, after which, interest will be paid in cash
     semiannually. The proceeds of the Notes Offering are to be used to prepay
     $75 million of the Nortel credit facility (see Note 7), to pay costs to
     build out the system, to fund operating working capital needs and for other
     general corporate purposes. Significant terms of the Notes include:

          o    Ranking - The Notes are senior unsecured obligations of Holdings,
               equal in right of payment to all future senior debt of Holdings
               and senior in right of payment to all future subordinated debt of
               Holdings;

                           (FORMERLY ALAMOSA PCS LLC)

                   NOTES TO FINANCIAL STATEMENTS - (CONTINUED)


          o    Guarantees - The Notes are unsecured obligations and will rank
               equally with all existing and future senior debt and senior to
               all existing and future subordinate debt. The Notes will be fully
               and unconditionally, jointly and severally guaranteed on a senior
               subordinated, unsecured basis, by all the existing and any future
               restricted subsidiaries of Holdings. In addition, Holdings will
               have no assets or operations other than its investments in
               Alamosa PCS Inc., and there are no non-guarantor subsidiaries.
               Therefore, financial statements of guarantor subsidiaries have
               been omitted;

          o    Optional Redemption - During the first thirty six (36) months
               after the Notes Offering, we may use net proceeds of an equity
               offering to redeem up to 35% of the accreted value of the notes
               at a redemption price of 112 7/8%;

          o    Change of Control - Upon a change of control as defined by the
               Notes Offering, we will be required to make an offer to purchase
               the notes at a price equal to 101% of the accreted value
               (original principal amount plus accrued interest) before February
               15, 2005, or 101% of the principal amount at maturity thereafter;

          o    Restrictive Covenants - The indenture governing the Notes contain
               covenants that, among other things and subject to important
               exceptions, limit our ability and the ability of our subsidiaries
               to incur additional debt, issue preferred stock, pay dividends,
               redeem capital stock or make other restricted payments or
               investments as defined by the Notes Offering, create liens on
               assets, merge, consolidate or dispose of assets, or enter into
               transactions with affiliates and change lines of business.


     Revision to credit facility with Nortel Networks, Inc. - On February 8,
     2000, Alamosa entered into an Amended and Restated Credit Facility (the
     "New Facility"), which replaced the $123 million facility entered into on
     June 10, 1999. The new agreement increased the facility to $250 million to
     provide for the financing of additional equipment needs to complete the
     buildout of the existing territory and the additional territory received
     from Sprint PCS (see following subsequent event). The terms of the New
     Facility are mostly the same as the original $123 million facility
     discussed in Note 7, but there are certain exceptions, key ones of which
     are detailed here. Under the New Facility, there are no equity commitments
     by former members of Alamosa. The interest rate on base rate loans was
     increased to prime plus 2.75% and on Eurodollar loans to LIBOR plus 3.75%.
     In addition, each of the tranches A, B and C were increased to $167.0
     million, $58.0 million and $25.0 million, respectively. The New Facility
     also provided for warrants representing 2% of the outstanding common stock
     of Holdings. These warrants were eliminated, by prior agreement, when
     Alamosa used $75 million of the equity contribution from Holdings to prepay
     the Nortel debt in February 2000. Under the circumstances provided in the
     New Credit Facility, those prepaid amounts may be re-borrowed.

     In addition to the $75 million prepayment, in conjunction with the closing
     of the New Facility, Alamosa also paid origination and other fees along
     with interest accrued of approximately $4.7 million.

     Revision to purchase contract with Nortel Networks, Inc. - On February 8,
     2000, the Company amended its equipment purchase contract with Nortel and
     increased its purchase commitment to $167 million. In addition, the
     requirement to pay a premium for purchases financed by Nortel (see Note 11)
     was eliminated once the Company's purchases under the contract exceed $82
     million.

     Contract for towers - On February 22, 2000, the Company entered into the
     Master Design Build Agreement with a tower contractor to provide towers in
     the expansion areas including Wisconsin.

Termination Date, are hereinafter collectively called the "Tranche B Loans".)

loans which remain outstanding after the Tranche C Commitment Termination Date,
are hereinafter collectively called the "Tranche C Loans".) The Borrower may

that the Borrower may reborrow the Tranche C Loans which have been prepaid in
accordance with Section 2.7(e) in the event that the Borrower elects to
increase the Tranche C Commitments in accordance with Section 2.13(c) by an
amount equal to or greater than the amount of such reborrowed Loan.

         (d) Continuation and Conversion of Loans. Subject to the terms and
conditions of this Agreement, the Borrower may borrow the Loans as Base Rate
Loans or Eurodollar Loans and, until the applicable Maturity Date, the Borrower

of the immediately preceding fiscal quarter). In addition, the Permitted

and during the continuation of a Default.

Loans made by each Lender shall be evidenced by a single promissory note of the
Borrower in substantially the form of Exhibit B-1, Exhibit B-2 and Exhibit B-3,
respectively, hereto dated the Closing Date (or such later date on which such
Lender becomes a party to this Agreement), payable to the order of such Lender
in a principal amount equal to the sum of (i) the aggregate principal amount of
such Loans of such Lender plus (ii) the aggregate principal amount of the
unfunded Commitment of such Lender relating to such Loans as originally in
effect. Each Lender is hereby authorized by the Borrower to endorse on the
schedule (or a continuation thereof) attached to the Notes of such Lender, to
the extent applicable, the date, amount and Type of and the Interest Period for
each applicable Loan made by such Lender to the Borrower and the amount of each
payment or prepayment of principal of such Loan received by such Lender,
provided that any failure by such Lender to make any such endorsement shall not
affect the obligations of the Borrower under any such Note or this Agreement in
respect of any such Loan.

         (b) Registered Notes. Any Lender that is not a U.S. Person and that
could become completely exempt from withholding of U.S. Taxes in respect of
payment of any Obligations due to such Lender hereunder relating to any of its
Loans if such Loans were in registered form for U.S. Federal income tax
purposes may request the Borrower (through the Administrative Agent), and the
Borrower agrees thereupon, to exchange such Lender's Note evidencing its Loans
for a promissory note registered as provided in Section 13.8(h) hereof (a
"Registered Note"). Registered Notes may not be exchanged for Notes that are
not in registered form.

         Section 2.3 Repayment of Loans. The Borrower shall pay to the
Administrative Agent for the account of each Lender the principal of the
Tranche A Loans, the Tranche B Loans and the Tranche C Loans outstanding as of

provided that: (a) the Borrower shall give the Administrative Agent notice of
each such prepayment, Conversion or Continuation as provided in Section 2.9,
(b) Eurodollar Loans may only be Converted on the last day of the Interest
Period and any prepayment of Eurodollar Loans on any day other than the last

compensation specified in Section 4.5, (c) except for Conversions of Eurodollar
Loans into Base Rate Loans, no Conversions or Continuations shall be made while
a Default has occurred and is continuing, and (d) optional prepayments of the
Loans shall be applied pro rata to the principal of the Loans prepaid in the
inverse order of the maturities of the then remaining installments of such
Loans. No amounts prepaid pursuant to this Section 2.6 may be reborrowed.


         Section 2.7 Mandatory Prepayments.

         (a) Asset Dispositions, etc. The Borrower will, within two Business
Days after any Loan Party receives any Net Proceeds of any Asset Disposition,
proceeds of any Insurance Recovery or proceeds of condemnation awards
aggregating in excess of $250,000 during any period of 12 consecutive months or
less (the amount of such proceeds exceeding $250,000 received during any such
period are herein called the "Excess Proceeds Amount"), pay to the
Administrative Agent, as a prepayment of the Loans, an aggregate amount equal
to the Excess Proceeds Amount; provided, however, that no such prepayment will
be required if and to the extent that the Excess Proceeds Amount is fully
re-invested in productive assets used in the ordinary course of such Loan
Party's business within 60 days of the receipt of such Excess Proceeds Amount
or, if and to the extent that such Excess Proceeds Amount has been, prior to
the expiration of such 60 day period, deposited into a cash collateral account
held by the Administrative Agent pursuant to an agreement in form and substance
satisfactory to the Administrative Agent, within 120 days of the receipt of
such Excess Proceeds Amount; provided, further, however, that the Excess
Proceeds Amount (or portion thereof) not so re-invested within 60 days of the
receipt thereof shall be deposited into a cash collateral account held by the
Administrative Agent pursuant to an agreement in form and substance
satisfactory to the Administrative Agent until such time as such amount is
either re-invested within 120 days of the receipt thereof or applied to the
Loans or other Obligations as provided in this Section 2.7.

         (b) Excess Cash Flow. The Borrower will, commencing on the first March
31st following the Tranche A Commitment Termination Date and on each March 31st
thereafter, pay (or cause to be paid) to the Administrative Agent, as a
prepayment of the Loans and other Obligations then outstanding, an aggregate
amount equal to 50% of Excess Cash Flow for the fiscal year then most recently
ended.

         (c) Borrowing Base. If at any time on or prior to the date that is six
months after the Tranche B Commitment Termination Date, the aggregate
outstanding principal amount of the Tranche B Loans and Tranche C Loans, the
proceeds of which have been used to pay Permitted Third-Party Expenses, exceeds
an amount equal to the lesser of (A) the Permitted Third-Party Expenses
Borrowing Base then in effect (as determined from time to time in accordance
with


CREDIT AGREEMENT - Page 38

Section 2.1(f)) or (B) the aggregate amount of the Tranche B Commitments and
the Tranche C Commitments as of the Tranche B Commitment Termination Date,

Loans and/or the Tranche C Loans.

         (d) Sale of the Service Area Network. The Borrower shall, concurrently

of the Loans, (ii) all interest accrued and unpaid with respect to all Loans,
and (iii) all other outstanding Obligations.

         (e) Holdings Senior Notes Issuance. The Borrower shall, substantially
concurrently with the date upon which Holdings receives any proceeds of any
issuance of Holdings Senior Notes, pay to the Administrative Agent, as a
prepayment of the Loans, an aggregate amount equal to the lesser of (i)
$75,000,000 or (ii) the aggregate principal amount of the Loans then
outstanding.

         (f) Application of Mandatory Prepayments. All prepayments pursuant to
Section 2.7(a) and Section 2.7(b) shall be applied pro rata to the outstanding
principal of the Tranche A Loans, the Tranche B Loans and the Tranche C Loans
(based upon the outstanding principal amounts of such Loans) in the inverse
order of the maturities of the then remaining installments of such Loans and
then to the remaining outstanding Obligations in such order as the
Administrative Agent may determine. All prepayments pursuant to Section 2.7(c)
shall be applied pro rata to the outstanding principal of the Tranche B Loans
and the Tranche C Loans (based upon the outstanding principal amounts of such
Loans) in the inverse order of the maturities of the then remaining
installments of such Loans and then to the remaining outstanding Obligations in
such order as the Administrative Agent may determine. All prepayments pursuant
to Section 2.7(e) shall be applied pro rata to the outstanding principal of the
Tranche A Loans, the Tranche B Loans and the Tranche C Loans (based upon the
outstanding principal amounts of such Loans) and shall be applied pro rata to
the then remaining installments of such Loans.

         (h) No Reborrowing. No amounts of the Loans prepaid pursuant to this
Section 2.7 may be reborrowed.

optional prepayment of principal of the Loans shall be in an amount at least
equal to $3,000,000 or an integral multiple of $100,000 in excess thereof
(borrowings, prepayments or Conversions of or into Loans of different Types or,
in the case of Eurodollar Loans, having different Interest Periods at the same
time hereunder shall be deemed separate borrowings, prepayments and Conversions
for purposes of the foregoing, one for each Type or Interest Period).

         Section 2.9 Certain Notices. Notices by the Borrower to the
Administrative Agent of terminations or reductions of Commitments, of
borrowings, Conversions, Continuations and prepayments of Loans and of the
duration of Interest Periods shall be irrevocable and shall be effective only

</TABLE>

Each such notice of termination or reduction shall specify the amount of the
Commitments to be terminated or reduced. Each such notice of borrowing,
Conversion, Continuation or prepayment shall specify the Loans to be borrowed,
Converted, Continued or prepaid and the amount (subject to Section 2.8 hereof)
and Type of the Loans to be borrowed, Converted, Continued or prepaid (and, in
the case of a Conversion, the Type of Loans to result from such Conversion) and
the date of borrowing, Conversion, Continuation or prepayment (which shall be a
Business Day). Each such notice of termination, reduction, borrowing,
Conversion, Continuation or prepayment shall be in the form of Exhibit C
hereto, appropriately completed as applicable. Each notice of borrowing (a
"Notice of Borrowing") (a) shall certify that all proceeds of the requested
Loans are, concurrently with the making of such Loans, being used by the
Borrower for the purpose specified in Section 2.10 and (b) shall be accompanied
by such other evidence as to use of the proceeds of such borrowing, as the
Administrative Agent may reasonably request from time to time. Each notice
which includes reference to the duration of an Interest Period shall specify
the Loans to which such Interest Period is to relate. The Administrative Agent
shall promptly notify the Lenders of the contents of each such notice. In the
event the Borrower fails to select the Type of Loan, or the duration of any
Interest Period for any Eurodollar Loan, within the time period and otherwise
as provided in this Section 2.9, such Loan (if outstanding as Eurodollar Loan)
will be automatically Converted into a Base Rate Loan on the last day of
preceding Interest Period for such Loan or (if outstanding as a Base Rate Loan)
will remain as, or (if not then outstanding) will be made as, a Base Rate Loan.
The Borrower may not borrow any Eurodollar Loans, Convert any Loans into
Eurodollar Loans or Continue any Loans as Eurodollar Loans if the interest rate
for such Eurodollar Loans would exceed the Maximum Rate.

         Section 2.10 Use of Proceeds.


         (a) Tranche A Loans. The Borrower agrees that all proceeds of the
Tranche A Loans shall be, promptly upon the Borrower's receipt thereof,

Nortel Networks Goods and Services with such proceeds and thereupon promptly

Subsidiary for its prior payment of) the purchase price for such Nortel
Networks Goods and Services provided by Nortel Networks for the construction of
the Service Area Network, provided, however, that proceeds of Tranche A Loans
may not be used to finance (or to reimburse the prior payment of) the purchase

price for Nortel Networks Goods and Services initially invoiced more than 12
months prior to the date of the making of such Loans, except that, on or prior

Operating Subsidiary to pay (or to reimburse such Operating Subsidiary for its
prior payment of) such Permitted Third-Party Expenses up to an amount equal to
the Permitted Third-Party Expenses Borrowing Base then in effect, provided,
however, that (i) as of any date of determination, the aggregate principal
amount of the Tranche B Loans and the Tranche C Loans at any and all times used
to pay Permitted Third-Party Expenses shall not exceed the Permitted
Third-Party Expenses Borrowing Base then in effect and (ii) proceeds of Tranche
B Loans may not be used to pay (or to reimburse the prior payment of) any
Permitted Third-Party Expenses initially invoiced more than 12 months prior to
the date of the making of such Loans, except that, on or prior to February 29,
2000, proceeds of Tranche B Loans may be used to reimburse the prior payment of

Tranche C Loans shall be, promptly upon the Borrower's receipt thereof, (i)
used by the Borrower to pay amounts payable under the Administrative Agent's
Letter on the Closing Date if and to the extent expressly permitted in the
Administrative Agent's Letter, (ii) used by the Borrower to pay interest
accrued on the Loans on or before the second anniversary of the Closing Date,
or (iii) contributed as equity to the capital of, or loaned to, the Operating

         Section 2.11 Fees

         (a) Subject to Section 13.12, the Borrower shall pay to the
Administrative Agent for the account of each applicable Lender a commitment fee
on the daily average unused or unfunded amount of each of such Lender's
Commitments, for the period from and including the date on which such Lender
(or its predecessor in interest with respect to Commitments assigned to such
Lender as to which a commitment fee has not previously been paid during the
applicable period) became a party hereto to but excluding the Tranche A
Commitment Termination Date, Tranche B Commitment Termination Date or the
Tranche C Commitment Termination Date, as the case may be, at the rate of
three-fourths of one percent (0.75%) per annum based on a 360 day year and the
actual number of days elapsed, which accrued commitment fees shall be payable
in arrears on each Quarterly Date and on the Tranche A Commitment Termination
Date, Tranche B Commitment Termination Date or the Tranche C Commitment
Termination Date, as the case may be; provided, however, that, notwithstanding
the foregoing, the commitment fees referred to in this Section 2.11(a)
preceding shall not commence to accrue until the date that is six months after
the Closing Date.

         (b) Subject to Section 13.12, the Borrower agrees to pay to the
Administrative Agent and Nortel Networks such additional fees as are specified
in the Administrative Agent's Letter, which fees shall be payable in such
amounts and on such dates as are specified therein.

         Section 2.12 Computations. Interest and fees payable by the Borrower
hereunder and under the other Loan Documents on all Loans shall be computed on
the basis of a year of 360 days and the actual number of days elapsed
(including the first day but excluding the last day) occurring in the period
for which payable unless, in the case of interest, such calculation would
result in a usurious rate, in which case interest shall be calculated on the
basis of a year of 365 or 366 days, as the case may be.

         Section 2.13 Termination or Reduction of Commitments.

         (a) Notwithstanding anything to the contrary contained in this
Agreement, each of the Commitments shall automatically terminate upon the
earlier to occur of (i) the occurrence of any Change in Control or (ii) any
sale, transfer or other disposition of the Service Area Network or any material
portion thereof.

         (b) Notwithstanding anything to the contrary contained in this
Agreement, on the date Holdings receives any net proceeds of any issuance of
Holdings Senior Notes, the Aggregate Commitments shall be reduced by an
aggregate amount such that, immediately after giving effect to such reduction,
the sum of (i) the aggregate outstanding principal amount of the Loans, plus
(ii) the aggregate outstanding principal amount of the Loans then previously
required to be prepaid or paid in accordance with Section 2.7 or Section 2.3,
respectively, plus (iii) the amount of the Aggregate Commitments does not
exceed $175,000,000. All reductions of the Aggregate Commitments pursuant to
this Section 2.13(b) shall be applied pro rata to reduce the Tranche A
Commitments, the Tranche B Commitments and the Tranche C Commitments (based
upon the outstanding principal amounts of such Commitments).


CREDIT AGREEMENT - Page 42


<PAGE>   50




         (c) Notwithstanding anything to the contrary contained in this
Agreement, each of the Tranche A Commitments, the Tranche B Commitments and the
Tranche C Commitments shall automatically be reduced, concurrently with the
making of any Tranche A Loans, Tranche B Loans or Tranche C Loans,
respectively, by an amount equal to the principal amount of such Tranche A
Loans, Tranche B Loans or Tranche C Loans, respectively, advanced; provided,
however, that, at the election of the Borrower and subject to the terms and
provisions of this Agreement, any of the Tranche A Loans, the Tranche B Loans
and/or the Tranche C Loans may be, at the election of the Borrower by its
giving of three Business Days' prior written notice of such election to the
Administrative Agent, increased by an amount not to exceed the amount by which
such Commitment was previously reduced pursuant to Section 2.13(b).

         (d) The Borrower shall have the right to terminate or reduce in part
the unused portion of the Tranche A Commitments, the Tranche B Commitments and
the Tranche C Commitments at any time and from time to time prior to the
Tranche A Commitment Termination Date, the Tranche B Commitment Termination
Date and the Tranche C Commitment Termination Date, respectively; provided,
however, that no such termination or reduction shall be effective unless the
Borrower shall have given notice of each such termination or reduction as
provided in Section 2.9, and each partial reduction of the Commitments shall be
in an aggregate amount at least equal to $3,000,000 or an integral multiple of
$100,000 in excess thereof.

         (e) Except as provided in Section 2.13(c), the Commitments may not be
reinstated after they have been terminated or increased after they have been
reduced.

                                   ARTICLE 3

                                    Payments

         Section 3.1 Method of Payment. All payments of principal, interest,
fees and other amounts to be made by the Borrower under this Agreement and the
other Loan Documents shall be made to the Administrative Agent at the Principal
Office for the account of each Lender's Applicable Lending Office in Dollars
and in immediately available funds, without setoff, deduction or counterclaim,
not later than 1:00 p.m. (New York, New York time) on the date on which such
payment shall become due (each such payment made after such time on such due
date to be deemed to have been made on the next succeeding Business Day). The
Borrower shall, at the time of making each such payment, specify to the
Administrative Agent the sums payable by the Borrower under this Agreement and
the other Loan Documents to which such payment is to be applied (and in the
event that the Borrower fails to so specify, or if an Event of Default has
occurred and is continuing, the Administrative Agent may apply such payment to
the Obligations in such order and manner as the Administrative Agent may elect,
subject to Section 3.2). Upon the occurrence and during the continuation of an
Event of Default, all proceeds of any Collateral and all other funds of the
Borrower or any Guarantor in the possession of the Administrative Agent or any
Lender, may be applied by the Administrative Agent to the Obligations in such
order and manner as the Administrative Agent may elect, subject to Section 3.2.
Each payment received by the Administrative Agent under this Agreement or any
other Loan Document for the account of a Lender shall be paid promptly to such
Lender, in immediately available funds, for the account of such


CREDIT AGREEMENT - Page 43



<PAGE>   51



Lender's Applicable Lending Office. Whenever any payment under this Agreement
or any other Loan Document shall be stated to be due on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of the
payment of interest and commitment fee, as the case may be.

         Section 3.2 Pro Rata Treatment. Except to the extent otherwise
provided in this Agreement: (a) each Loan shall be made by the Lenders under
Section 2.1, each payment of commitment fees under Section 2.11(a) shall be
made for the account of the Lenders, and each termination or reduction of the
Commitments under Section 2.13 shall be applied to the Commitments of the
Lenders, pro rata according to the respective unused Commitments; (b) the
making, Conversion and Continuation of Loans of a particular Type (other than
Conversions provided for by Section 4.4) shall be made pro rata among the
Lenders holding Loans of such Type according to the amounts of their respective
Commitments; (c) each payment and prepayment by the Borrower of principal of or
interest on Loans of a particular Type shall be made to the Administrative
Agent for the account of the Lenders holding Loans of such Type pro rata in
accordance with the respective unpaid principal amounts of such Loans held by
such Lenders; and (d) Interest Periods for Loans of a particular Type shall be
allocated among the Lenders holding Loans of such Type pro rata according to
the respective principal amounts held by such Lenders.

         Section 3.3 Sharing of Payments, Etc. If a Lender shall obtain payment
of any principal of or interest on any of the Obligations due to such Lender
hereunder through the exercise of any right of setoff, banker's lien,
counterclaim or similar right, or otherwise, it shall promptly purchase from
the other Lenders participations in the Obligations held by the other Lenders
in such amounts, and make such adjustments from time to time, as shall be
equitable to the end that all the Lenders shall share pro rata in accordance
with the unpaid principal and interest on the Obligations then due to each of
them. To such end, all of the Lenders shall make appropriate adjustments among
themselves (by the resale of participations sold or otherwise) if all or any
portion of such excess payment is thereafter rescinded or must otherwise be
restored. Each of the Loan Parties agrees, to the fullest extent it may
effectively do so under applicable law, that any Lender so purchasing a
participation in the Obligations by the other Lenders may exercise all rights
of setoff, banker's lien, counterclaim or similar rights with respect to such
participation as fully as if such Lender were a direct holder of Obligations in
the amount of such participation. Nothing contained herein shall require any
Lender to exercise any such right or shall affect the right of any Lender to
exercise, and retain the benefits of exercising, any such right with respect to
any other indebtedness, liability or obligation of any of the Loan Parties.

         Section 3.4 Non-Receipt of Funds by the Administrative Agent. Unless
the Administrative Agent shall have been notified by a Lender or the Borrower
(the "Payor") prior to the date on which such Lender is to make payment to the
Administrative Agent of the proceeds of a Loan to be made by it hereunder or
the Borrower is to make a payment to the Administrative Agent for the account
of one or more of the Lenders, as the case may be (such payment being herein
called the "Required Payment"), which notice shall be effective upon receipt,
that the Payor does not intend to make the Required Payment to the
Administrative Agent, the Administrative Agent may assume that the Required
Payment has been made and may, in reliance upon such assumption (but shall not
be required to), make the amount thereof available to the intended recipient on
such date and, if the


CREDIT AGREEMENT - Page 44



<PAGE>   52



Payor has not in fact made the Required Payment to the Administrative Agent,
the recipient of such payment shall, on demand, pay to the Administrative Agent
the amount made available to it together with interest thereon in respect of
the period commencing on the date such amount was so made available by the
Administrative Agent until the date the Administrative Agent recovers such
amount at a rate per annum equal to the Federal Funds Rate for such period.

         Section 3.5 Taxes.

         (a) All payments by the Borrower and/or any Guarantor of principal of
and interest on the Loans and of all fees and other amounts payable under the
Loan Documents shall be made free and clear of, and without withholding or
deduction by reason of, any present or future taxes, levies, duties, imposts,
assessments or other charges levied or imposed by any Governmental Authority
(other than franchise taxes and taxes on the overall net income of any Lender).
If any such taxes, levies, duties, imposts, assessments or other charges are so
levied or imposed, the Borrower will (i) make additional payments in such
amounts so that every net payment of principal of and interest on the Loans and
of all other amounts payable by it under the Loan Documents, after withholding
or deduction for or on account of any such present or future taxes, levies,
duties, imposts, assessments or other charges (including any tax imposed on or
measured by net income of a Lender attributable to payments made to or on
behalf of a Lender pursuant to this Section 3.5 and any penalties or interest
attributable to such payments), will not be less than the amount provided for
herein or therein absent such withholding or deduction (provided that the
Borrower shall not have any obligation to pay such additional amounts to any
Lender to the extent that such taxes, levies, duties, imposts, assessments or
other charges are levied or imposed by reason of the failure of such Lender to
comply with the provisions of Section 3.6), (ii) make such withholding or
deduction and (iii) remit the full amount deducted or withheld to the relevant
Governmental Authority in accordance with applicable law. Without limiting the
generality of the foregoing, the Borrower will, upon written request of any
Lender, reimburse each such Lender for the amount of (A) such taxes, levies,
duties, imports, assessments or other charges so levied or imposed by any
Governmental Authority and paid by such Lender as a result of payments made by
the Borrower under or with respect to the Loans other than such taxes, levies,
duties, imports, assessments and other charges previously withheld or deducted
by the Borrower which have previously resulted in the payment of the required
additional amount to such Lender, and (B) such taxes, levies, duties,
assessments and other charges so levied or imposed with respect to any Lender
reimbursement under the foregoing clause (A), so that the net amount received
by such Lender (net of payments made under or with respect to the Loans) after
such reimbursement will not be less than the net amount such Lender would have
received if such taxes, levies, duties, assessments and other charges on such
reimbursement had not been levied or imposed. The Borrower shall furnish
promptly to the Administrative Agent for distribution to each affected Lender,
as the case may be, upon request of such Lender, official receipts evidencing
any such payment, withholding or reduction.

         (b) The Borrower will indemnify the Administrative Agent and each
Lender (without duplication) against, and reimburse the Administrative Agent
and each Lender for, all present and future taxes, levies, duties, imposts,
assessments or other charges (including interest and penalties) levied or
collected (whether or not legally or correctly imposed, assessed, levied or
collected), excluding, however, any taxes imposed on the overall net income of
the Administrative Agent or


CREDIT AGREEMENT - Page 45

such Lender or any lending office of the Administrative Agent or such Lender by
any jurisdiction in which the Administrative Agent or such Lender or any such
lending office is located, on or in respect of this Agreement, any of the Loan
Documents or the Obligations or any portion thereof (the "reimbursable taxes").
Any such indemnification shall be on an after-tax basis, taking into account
any such reimbursable taxes imposed on the amounts paid as indemnity.

         (c) Without prejudice to the survival of any other term or provision
of this Agreement, the obligations of the Borrower and the Guarantors under
this Section 3.5 shall survive the payment of the Loans and the other
Obligations and termination of the Commitments.

         Section 3.6 Withholding Tax Exemption. Each Lender that is not
incorporated or otherwise formed under the laws of the U.S. or a state thereof
agrees that it will, prior to or on or about the Closing Date or the date upon
which it initially becomes a party to this Agreement and if it is legally able
to do so, deliver to the Borrower and the Administrative Agent two duly
completed copies of U.S. Internal Revenue Service Form W-8ECI or W-8BEN or
other equivalent successor form, as appropriate, certifying in any case that
such Lender is entitled to receive payments from the Borrower under any Loan
Document without deduction or withholding of any U.S. federal income taxes.
Each Lender which so delivers a Form W-8ECI or W-8BEN or other equivalent
successor form, as appropriate, further undertakes to deliver to the Borrower
and the Administrative Agent two additional copies of such form (or a successor
form) on or before the date such form expires or becomes obsolete or after the
occurrence of any event requiring a change in the most recent form so delivered
by it, and such amendments thereto or extensions or renewals thereof as may be
reasonably requested by the Borrower or the Administrative Agent, in each case
certifying that such Lender is entitled to receive payments from the Borrower
under any Loan Document without deduction or withholding of any U.S. federal
income taxes, unless an event (including without limitation any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender advises the Borrower and the
Administrative Agent that it is not capable of receiving such payments without
any deduction or withholding of U.S. federal income tax.

         Section 3.7 Reinstatement of Obligations. Notwithstanding anything to
the contrary contained in this Agreement or any other Loan Document, if the
payment of any amount of principal of or interest with respect to the Loans or
any other amount of the Obligations, or any portion thereof, is rescinded,
voided or must otherwise be refunded by the Administrative Agent or any Lender
upon the insolvency, bankruptcy or reorganization of any Loan Party or
otherwise for any reason whatsoever, then each of (a) the Obligations, (b) the
Loan Documents (including, without limitation, this Agreement, the Notes and
the Security Documents), (c) the indebtedness, liabilities and obligations of
the Borrower and any other Loan Parties and (d) all Liens for the benefit of
the Administrative Agent and the Lenders created under or evidenced by the Loan
Documents, will be automatically reinstated and become automatically effective
and in full force and effect, all to the extent that and as though such payment
so rescinded, voided or otherwise refunded had never been made.

         Section 3.8 No Force Majeure, Disputes. The obligations of the
Borrower and the other Loan Parties (as applicable), or any one or more of
them, to pay all amounts due under the Loans and the other Obligations shall
not be affected by (a) any set-off, counterclaim, recoupment, deduction,
abatement, suspension, diminution, reduction, defense or other right which the
Borrower or any other Loan Party may have against the Vendor for any reason
whatsoever arising under or pursuant to the Supply Agreement or otherwise
relating to the purchase of goods or services from the Vendor, (b) any defect
in the condition, design, operation or fitness for use of, or any damage to or
loss or destruction of, any equipment or material or service provided by the
Vendor, (c) any insolvency, bankruptcy, reorganization or similar proceedings
by or against the Borrower or any other Loan Party or affecting any of its
Properties, (d) any action of any Governmental Authority or any damage to or
destruction of or any taking of the Property of the Borrower or any other Loan
Party or any part thereof, (e) any change, waiver, extension, indulgence or
failure to perform or comply with, or other action or omission herein or in the
other Loan Documents (except for express written modifications to this
Agreement or other Loan Documents as and in the manner permitted under this
Agreement or the other Loan Documents), (f) any dissolution of the Borrower or
any other Loan Party, (g) any inability or illegality with respect to the use
or ownership of the Property of the Borrower or any other Loan Party, (h) any
failure to obtain, or expiration, suspension or other termination of, or
interruption to, any required licenses, permits, consents, authorizations,
approvals or other legal requirements, (i) the invalidity or unenforceability
of any of the Loan Documents or any other infirmity therein or any lack of
power or authority of the Administrative Agent or any Lender or the Borrower or
any other Loan Party, or (j) any other event or circumstance whatsoever,
whether or not similar to any of the foregoing and whether or not the Borrower
or any other Loan Party shall have notice or knowledge of any of the foregoing,
it being the intention of the Administrative Agent and the Lenders and the
Borrower and the other Loan Parties that the Obligations of the Borrower and/or
the other Loan Parties (as applicable) shall be absolute and unconditional and
shall be separate and independent covenants and agreements and shall continue
unaffected unless the requirements to pay or perform the same shall have been
terminated pursuant to an express provision thereof or of any of the other Loan
Documents.

                                   ARTICLE 4

                        Yield Protection and Illegality

         Section 4.1 Additional Costs.

         (a) The Borrower shall pay directly to each Lender from time to time,
promptly upon the request of such Lender, the costs incurred by such Lender
which such Lender determines are attributable to its making or maintaining of
any Eurodollar Loans or its obligation to make any of such Loans, or any
reduction in any amount receivable by such Lender hereunder in respect of any
such Loans or obligations (such increases in costs and reductions in amounts
receivable being herein called "Additional Costs"), resulting from any
Regulatory Change which:

                  (i) changes the basis of taxation of any amounts payable to
         such Lender under this Agreement or its Notes in respect of any of
         such Loans (other than taxes imposed on the overall net income of such
         Lender or its Applicable Lending Office for any of such Loans


CREDIT AGREEMENT - Page 47



<PAGE>   55



         by the jurisdiction in which such Lender has its principal office or
         such Applicable Lending Office);

                  (ii) imposes or modifies any reserve, special deposit,
         minimum capital, capital ratio or similar requirement relating to any
         extensions of credit or other assets of, or any deposits with or other
         liabilities or commitments of, such Lender (including any of such
         Loans or any deposits referred to in the definition of "Eurodollar
         Rate" in Section 1.1 hereof, but excluding the Reserve Requirement to
         the extent it is included in the calculation of the Adjusted
         Eurodollar Rate); or

                  (iii) imposes any other condition affecting this Agreement or
         the Notes or any extensions of credit or liabilities or commitments
         contemplated hereunder or thereunder.

Each Lender will notify the Borrower (with a copy to the Administrative Agent)
of any event occurring after the Closing Date which will entitle such Lender to
compensation pursuant to this Section 4.1(a) as promptly as practicable after
it obtains knowledge thereof and determines to request such compensation, and
(if so requested by the Borrower) will designate a different Applicable Lending
Office for the Eurodollar Loans of such Lender if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
sole opinion of such Lender, violate any law, rule or regulation or be in any
way disadvantageous to such Lender, provided that such Lender shall have no
obligation to so designate an Applicable Lending Office located in the U.S.
Each Lender will furnish the Borrower with a certificate setting forth the
basis and the amount of each request of such Lender for compensation under this
Section 4.1(a). If any Lender requests compensation from the Borrower under
this Section 4.1(a), the Borrower may, by notice to such Lender (with a copy to
the Administrative Agent), suspend the obligation of such Lender to make or
Continue making, or Convert Base Rate Loans into, Eurodollar Loans until the
Regulatory Change giving rise to such request ceases to be in effect (in which
case the provisions of Section 4.4 hereof shall be applicable).

         (b) Without limiting the effect of the foregoing provisions of this
Section 4.1, in the event that, by reason of any Regulatory Change, any Lender
either (i) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of
such Lender which includes deposits by reference to which the interest rate on
Eurodollar Loans is determined as provided in this Agreement or a category of
extensions of credit or other assets of such Lender which includes Eurodollar
Loans or (ii) becomes subject to restrictions on the amount of such a category
of liabilities or assets which it may hold, then, if such Lender so elects by
notice to the Borrower (with a copy to the Administrative Agent), the
obligation of such Lender to make or Continue making, or Convert Base Rate
Loans into, Eurodollar Loans hereunder shall be suspended until such Regulatory
Change ceases to be in effect (in which case the provisions of Section 4.4
hereof shall be applicable).

         (c) Determinations and allocations by any Lender for purposes of this
Section 4.1 of the effect of any Regulatory Change on its costs of maintaining
its obligation to make Loans or of making or maintaining Loans or on amounts
receivable by it in respect of Loans and of the additional amounts required to
compensate such Lender in respect of any Additional Costs, shall be conclusive


CREDIT AGREEMENT - Page 48




<PAGE>   56



in the absence of manifest error, provided that such determinations and
allocations are made on a reasonable basis. Notwithstanding anything to the
contrary contained herein, the Borrower shall not be required to make any
payment of Additional Costs to any Lender pursuant to this Section 4.1 with
respect to Additional Costs relating to any period of time which is more than
180 days prior to such Lender's request for such Additional Costs, provided
that the foregoing provisions of this sentence shall not apply to Additional
Costs attributable to any Regulatory Change which takes effect retroactively.

         Section 4.2 Limitation on Types of Loans. Anything herein to the
contrary notwithstanding, if with respect to any Eurodollar Loans for any
Interest Period therefor:

         (a) the Administrative Agent determines (which determination shall be
conclusive absent manifest error) that quotations of interest rates for the
relevant deposits referred to in the definition of "Eurodollar Rate" in Section
1.1 hereof are not being provided in the relative amounts or for the relative
maturities for purposes of determining the rate of interest for such Loans as
provided in this Agreement; or

         (b) the Required Lenders determine (which determination shall be
conclusive absent manifest error) and notify the Administrative Agent that the
relevant rates of interest referred to in the definition of "Eurodollar Rate"
or "Adjusted Eurodollar Rate" in Section 1.1 hereof on the basis of which the
rate of interest for such Loans for such Interest Period is to be determined do
not accurately reflect the cost to the Lenders of making or maintaining such
Loans for such Interest Period;

then the Administrative Agent shall give the Borrower prompt notice thereof
and, so long as such condition remains in effect, the Lenders shall be under no
obligation to make Eurodollar Loans or to Convert Base Rate Loans into
Eurodollar Loans and the Borrower shall, on the last day(s) of the then current
Interest Period(s) for the outstanding Eurodollar Loans, either prepay such
Loans or Convert such Loans into Base Rate Loans in accordance with the terms
of this Agreement.

         Section 4.3 Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to (a) honor its obligation to make Eurodollar Loans
or (b) maintain Eurodollar Loans, then such Lender shall promptly notify the
Borrower (with a copy to the Administrative Agent) thereof and such Lender's
obligation to make or maintain Eurodollar Loans and to Convert Base Rate Loans
into Eurodollar Loans hereunder shall be suspended until such time as such
Lender may again make and maintain Eurodollar Loans (in which case the
provisions of Section 4.4 hereof shall be applicable).

         Section 4.4 Treatment of Affected Loans. If the obligation of any
Lender to make or Continue, or to Convert Base Rate Loans into, Eurodollar
Loans is suspended pursuant to Section 4.1 or 4.3 hereof, such Lender's
Eurodollar Loans shall be automatically Converted into Base Rate Loans on the
last day(s) of the then current Interest Period(s) for the Eurodollar Loans
(or, in the case of a Conversion required by Section 4.1(b) or 4.3 hereof, on
such earlier date as such Lender may specify to the Borrower with a copy to the
Administrative Agent) and, unless and until such Lender


CREDIT AGREEMENT - Page 49



<PAGE>   57



gives notice as provided below that the circumstances specified in Section 4.1
or 4.3 hereof which gave rise to such Conversion no longer exist:

         (a) to the extent that such Lender's Eurodollar Loans have been so
Converted, all payments and prepayments of principal which would otherwise be
applied to such Lender's Eurodollar Loans shall be applied instead to its Base
Rate Loans; and

         (b) all Loans which would otherwise be made or Continued by such
Lender as Eurodollar Loans shall be made as or Converted into Base Rate Loans
and all Loans of such Lender which would otherwise be Converted into Eurodollar
Loans shall be Converted instead into (or shall remain as) Base Rate Loans.

If such Lender gives notice to the Borrower that the circumstances specified in
Section 4.1 or 4.3 hereof which gave rise to the Conversion of such Lender's
Eurodollar Loans pursuant to this Section 4.4 no longer exist (which such
Lender agrees to do promptly upon such circumstances ceasing to exist) at a
time when Eurodollar Loans are outstanding, such Lender's Base Rate Loans shall
be automatically Converted, on the first day(s) of the next succeeding Interest
Period(s) for such outstanding Eurodollar Loans, to the extent necessary so
that, after giving effect thereto, all Loans held by the Lenders holding
Eurodollar Loans and by such Lender are held pro rata (as to principal amounts,
Types and Interest Periods) in accordance with their respective Commitments.

         Section 4.5 Compensation. The Borrower shall pay to the Administrative
Agent for the account of each Lender, promptly upon the request of such Lender
through the Administrative Agent, such amount or amounts as shall be sufficient
(in the reasonable opinion of such Lender) to compensate it for any loss, cost
or expense incurred by it as a result of:

         (a) Any payment, prepayment or Conversion of a Eurodollar Loan for any
reason (including, without limitation, the acceleration of the outstanding
Loans pursuant to Section 11.2) on a date other than the last day of an
Interest Period for such Loan; or

         (b) Any failure by the Borrower for any reason (including, without
limitation, the failure of any conditions precedent specified in Article 6 to
be satisfied) to borrow, Convert or prepay a Eurodollar Loan on the date for
such borrowing, Conversion or prepayment specified in the relevant notice of
borrowing, prepayment or Conversion under this Agreement.

         Section 4.6 Capital Adequacy. If, after the Closing Date, any Lender
shall have determined that the adoption or implementation of any applicable
law, rule or regulation regarding capital adequacy (including, without
limitation, any law, rule or regulation implementing the Basle Accord), or any
change therein, or any change in the interpretation or administration thereof
by any central bank or other Governmental Authority charged with the
interpretation or administration thereof, or compliance by such Lender (or its
parent) with any guideline, request or directive regarding capital adequacy
(whether or not having the force of law) of any central bank or other
Governmental Authority (including, without limitation, any guideline or other
requirement implementing the Basle Accord), has or would have the effect of
reducing the rate of return on such Lender's (or its parent's) capital as a
consequence of its obligations hereunder or the transactions


CREDIT AGREEMENT - Page 50



<PAGE>   58



contemplated hereby to a level below that which such Lender (or its parent)
could have achieved but for such adoption, implementation, change or compliance
(taking into consideration such Lender's policies with respect to capital
adequacy) by an amount reasonably deemed by such Lender to be material, then
from time to time, within ten Business Days after demand by such Lender (with a
copy to the Administrative Agent), the Borrower shall pay to such Lender such
additional amount or amounts as will compensate such Lender (or its parent) for
such reduction. A certificate of such Lender claiming compensation under this
Section 4.6 and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive absent manifest error, provided that the
determination thereof is made on a reasonable basis. In determining such amount
or amounts, such Lender may use any reasonable averaging and attribution
methods. Notwithstanding anything to the contrary contained herein, the
Borrower shall not be required to make any payment of additional amounts to any
Lender pursuant to this Section 4.6 with respect to additional amounts relating
to any period of time which is more than 180 days prior to such Lender's
request for such additional amounts, provided that the foregoing provisions of
this sentence shall not apply to additional amounts attributable to any
Regulatory Change which takes effect retroactively.

         Section 4.7 Additional Interest on Eurodollar Loans. Without
duplication of Section 2.4 or amounts directly included in the definition of
the term "Adjusted Eurodollar Rate", the Borrower shall pay, directly to each
Lender from time to time, additional interest on the unpaid principal amount of
each Eurodollar Loan held by such Lender, from the date of the making of such
Eurodollar Loan until such principal amount is paid in full, at an interest
rate per annum determined by such Lender in good faith equal to the positive
remainder (if any) of (a) the Adjusted Eurodollar Rate applicable to such
Eurodollar Loan minus (b) the Eurodollar Rate applicable to such Eurodollar
Loan. Each payment of additional interest pursuant to this Section 4.7 shall be
payable by the Borrower on each date upon which interest is payable on such
Eurodollar Loan pursuant to Section 2.4(b); provided, however, that the
Borrower shall not be obligated to make any such payment of additional interest
until the first Business Day after the date when the Borrower has been informed
(i) that such Lender is subject to a Reserve Requirement and (ii) of the amount
of such Reserve Requirement (after which time the Borrower shall be obligated
to make all such payments of additional interest, including, without
limitation, such payment of additional interest that otherwise would have been
payable by the Borrower on or prior to such time had the Borrower been earlier
informed).

         Section 4.8 Replacement of Lenders. If at any time a Lender, other
than Nortel Networks, becomes a Gross Up Lender, the Borrower shall have the
right to replace such Lender with another Person; provided that (a) such other
Person shall be an Eligible Assignee and such other Person shall execute an
Assignment and Acceptance, (b) neither the Administrative Agent nor any Lender
shall have any obligation to the Borrower to find such other Person, (c) in the
event of a replacement of a Gross Up Lender, in order for the Borrower to be
entitled to replace such Lender, such replacement must take place no later than
180 days after the date the Gross Up Lender shall notify the Borrower and the
Administrative Agent of its desire to be paid any amounts pursuant to Section
3.5, 4.1 or 4.6, and (d) if the Borrower replaces one Gross Up Lender, it must
replace all Gross Up Lenders or replace all Gross Up Lenders on a pro rata
basis. Each Lender, other than Nortel Networks, agrees to its replacement at
the option of the Borrower pursuant to this Section 4.8 and in accordance with
Section 13.8; provided that the successor Lender shall purchase without


CREDIT AGREEMENT - Page 51



<PAGE>   59



recourse such Lender's interest in the Obligations of the Borrower to such
Lender for cash in an aggregate amount equal to the aggregate unpaid principal
thereof, all unpaid interest accrued thereon, all unpaid commitment fees
accrued for the account of such Lender, any breakage costs incurred by the
selling Lender because of the prepayment of any Eurodollar Loans, all other
fees (if any) applicable thereto and all other amounts (including any amounts
under this Article 4) then owing to such Lender hereunder or under any other
Loan Document and the Loan Parties shall execute a release addressed to such
Lender releasing such Lender from all claims arising in connection with the
Loan Documents.

The Borrower, Holdings and the Operating Subsidiaries shall, and shall cause

Mortgage or an amendment or modification to an existing Mortgage covering all
fee real Property owned on the Closing Date or acquired by the Borrower or any

and substance reasonably satisfactory to the Administrative Agent; provided,
however, that, with respect to any particular parcel of real Property having a

policy of title insurance and a current survey shall not be required to be
provided if the aggregate fair market value (inclusive of fixtures) of all real
Property as to which the same have not been provided does not exceed
$1,000,000; provided, further, however, that a mortgagee policy of title
insurance shall be required to be provided with respect to each real Property

Agent's perfected, first priority Lien on the Collateral or Property affected
thereby, the Administrative Agent's access to such Collateral or Property and

         Section 5.5 Setoff. If an Event of Default shall have occurred and be
continuing, each Lender is hereby authorized at any time and from time to time,
without notice to the Borrower or any other Loan Party (any such notice being
hereby expressly waived by the Borrower and the other Loan Parties), to set off
and apply any and all deposits (general or special, time or demand, provisional
or final excluding any trust accounts) at any time held and other indebtedness
at any time owing by such Lender to or for the credit or the account of the
Borrower or any Guarantor against any and all of the Obligations of the
Borrower or such Guarantor now or hereafter existing under this Agreement, such
Lender's Note or any other Loan Document, irrespective of whether or not the
Administrative Agent or such Lender shall have made any demand under this
Agreement, such Lender's Note or any such other Loan Document and although such
Obligations may be unmatured. Each Lender agrees promptly to notify the
Borrower (with a copy to the Administrative Agent) after any such setoff and
application, provided that the failure to give such notice shall not affect the
validity of such setoff and application. The rights and remedies of each Lender
hereunder are in addition to other rights and remedies (including, without
limitation, other rights of setoff) which such Lender may have.

         Section 5.6 Further Assurances. In addition to the foregoing, the
Borrower, Holdings and the Operating Subsidiaries will, and will cause each of
the other Loan Parties (as applicable) to, execute and/or deliver such further
agreements, documents and instruments (including, without limitation, Security
Documents and financing statements) as the Administrative Agent may reasonably
request from time to time in order for it to obtain and maintain valid,
perfected first priority Liens required to be granted to secure the payment and
performance of the Obligations in accordance with this Article 5.

Parties is in compliance in all material respects with all applicable
provisions of ERISA and the Code. Neither a Reportable Event nor a Prohibited
Transaction has occurred within the last 60 months with respect to any Plan
that could reasonably be expected have a Material Adverse Effect. No notice of
intent to terminate a Pension Plan has been filed, nor has any Pension Plan
been terminated. No circumstances exist which constitute grounds entitling the
PBGC to institute proceedings to terminate, or appoint a trustee to administer,
a Pension Plan, nor has the PBGC instituted any such proceedings. Neither any
Loan Party nor any ERISA Affiliate has completely or partially withdrawn from a
Multiemployer Plan. Each of the Loan Parties and each ERISA Affiliate have met
their minimum funding requirements under ERISA and the Code or with respect to
all of their Pension Plans subject to such requirements, and, as of the Closing
Date except as specified on Schedule 7.13, the present value of all vested
benefits under each funded Plan (exclusive of any Multiemployer Plan) does not
and will not exceed the fair market value of all such Plan assets allocable to
such benefits, as determined on the most recent valuation date of such Plan and
in accordance with ERISA. Neither any Loan Party nor any ERISA Affiliate has
incurred any liability to the PBGC under ERISA. No litigation is pending or, to
any Loan Party's knowledge, threatened concerning or involving any Plan that
could reasonably be expected to have a Material Adverse Effect. There are no
unfunded or unreserved liabilities (on either a going- concern basis or a
wind-up basis) relating to any Plan that could, individually or in the
aggregate, have a Material Adverse Effect if the Borrower were required to fund
or reserve such liability in full. As of the Closing Date, no funding waivers
have been or will have been requested or granted under Section 412 of the Code
with respect to any Plan. No unfunded or unreserved liability for benefits
under any Plan or Plans (exclusive of any Multiemployer Plans) exceeds
$500,000, with respect to any such Plan, or $1,000,000 with respect to all such
Plans, in the aggregate as of the Closing Date, on either a going-concern basis
or a wind-up basis.

as is usually carried by such corporations or entities, provided that in any
event each of the Loan Parties (if and to the extent that it has Properties
that are capable of being covered by the following insurance) will maintain:

                  (i) Property Insurance. Insurance against loss or damage
         covering substantially all of the tangible real and personal Property
         (including, without limitation, the Service Area Network and related
         equipment) and improvements of such Person by reason of any Peril (as
         defined below) in such amounts (subject to any deductibles as shall be
         satisfactory to the Administrative Agent) as shall be reasonable and
         customary and sufficient to avoid the insured named therein from
         becoming a co-insurer of any loss under such policy, but in any


CREDIT AGREEMENT - Page 74



<PAGE>   82



         event in such amounts as are reasonably available as determined by the
         Borrower's independent insurance broker reasonably acceptable to the
         Administrative Agent.

                  (ii) Automobile Liability Insurance for Bodily Injury and
         Property Damage. Insurance in respect of all vehicles (whether owned,
         hired or rented by such Person) at any time located at, or used in
         connection with, its Properties or operations against liabilities for
         bodily injury and Property damage in such amounts as are then
         customary for vehicles used in connection with similar Properties and
         businesses, but in any event to the extent required by applicable law.

                  (iii) Comprehensive General Liability Insurance. Insurance
         against claims for bodily injury, death or Property damage occurring
         on, in or about the Property (and adjoining streets, sidewalks and

         Property similar in use in the jurisdictions where such Properties are
         located.

                  (iv) Worker's Compensation Insurance. Worker's compensation
         insurance (including employers' liability insurance) to the extent
         required by applicable law, which may be self-insurance to the extent
         permitted by applicable law.

Without limiting the generality of the foregoing, the Borrower and its
Subsidiaries shall purchase and maintain in effect all-risk, property and
casualty insurance (including casualty insurance covering earthquake and flood
damage) covering all tangible, real and personal Property (including, without
limitation, the Service Area Network and Nortel Networks Equipment and related
equipment) and liability insurance covering the operations of the Borrower and
its Subsidiaries, in each case in such amounts (not to exceed the greater of
original cost or fair market value) and as otherwise reasonably acceptable to
the Administrative Agent and the Required Lenders. Such insurance shall be
written by financially responsible companies selected by the Borrower and
having an A.M. Best Rating of "A-" or better and being in a financial size
category of "VI" or larger, or by other companies reasonably acceptable to the
Administrative Agent. Each policy referred to in this Section 8.5 shall name
the Administrative Agent (for the benefit of itself and the other Lenders) as
loss payee (with respect to casualty insurance policies) and additional insured
(with respect to liability insurance policies) and shall provide that it will
not be canceled, amended or reduced except after not less than 30 days' prior
written notice to the Administrative Agent and shall also provide that the
interests of the Administrative Agent and the Lenders shall not be invalidated
or reduced by any act, omission or negligence of the Borrower or any of its
Subsidiaries. The Borrower will advise the Administrative Agent promptly of any
policy cancellation, reduction or amendment. For purposes hereof, the term
"Peril" shall mean, collectively, fire, lightning, flood, windstorm, hail,
explosion, riot and civil commotion, vandalism and malicious mischief, damage
from aircraft, vehicles and smoke and other perils covered by the "all-risk"
endorsement then in use in the jurisdictions where the Properties of the Loan
Parties are located.

         (b) Each of the Loan Parties will cause each Insurance Recovery (other
than any portion of an Insurance Recovery payable to a landlord to repair or
replace Property leased by the Borrower or any of its Subsidiaries) payable by
any insurance company to be deposited promptly with the Administrative Agent as
security for the Obligations if a Default has then occurred and is continuing,


CREDIT AGREEMENT - Page 75

application against the Obligations if and to the extent required in accordance
with Section 2.7(a).

         (c) If a Default shall have occurred and be continuing, each of the
Loan Parties will cause all proceeds of insurance paid on account of the loss
of or damage to any Property of any Loan Party and all awards of compensation
for any Property of any Loan Party taken by condemnation or eminent domain to
be promptly paid directly to the Administrative Agent to be applied against or

Agent and the Required Lenders.

         Section 8.6 Inspection Rights. Each of the Loan Parties will permit
representatives and agents of the Administrative Agent and each Lender, during

its officers and independent certified public accountants. Each of the Loan
Parties will authorize its accountants in writing (with a copy to the

or its representatives may, at any time and from time to time at the Borrower's
expense, conduct field exams to verify the Permitted Third-Party Expenses
Borrowing Base and for such other purposes as the Administrative Agent may
reasonably request, provided, however, that such exams shall be at the
Borrower's expense only if a Default has then occurred and is continuing.
Without limiting the generality of the foregoing, the Administrative Agent may
retain outside auditors to evaluate and monitor Permitted Third-Party Expenses
Borrowing Base Reports, inventory valuations and other matters relevant to the
determination of the Permitted Third-Party Expenses Borrowing Base, all at the
expense of Borrower after the occurrence and during the continuance of a
Default.

         Section 8.7 Keeping Books and Records. Each of the Loan Parties will
maintain appropriate books of record and account in accordance with GAAP
consistently applied in which true, full and correct entries will be made of
all their respective dealings and business affairs. If any changes in
accounting principles from those used in the preparation of the financial
statements referenced in Section 8.1 are hereafter required or permitted by
GAAP and are adopted by the Borrower with the concurrence of its independent
certified public accountants and such changes in GAAP result in a change in the
method of calculation or the interpretation of any of the covenants, standards
or terms contained in this Agreement, the Loan Parties and the Required Lenders
agree to amend any such affected terms and provisions so as to reflect such
changes in GAAP with the result that the criteria for evaluating the financial
condition or performance of the Loan Parties shall be the same after such
changes in GAAP as if such changes in GAAP had not been made.

         Section 8.8 Compliance with Laws. Each of the Loan Parties will comply
with all Governmental Requirements applicable to the operation of its business
(including, without limitation, the Communications Act, any rule or regulation

such further action as may be reasonably requested by the Administrative Agent
to carry out the provisions and purposes of this Agreement and the other Loan
Documents, to evidence the Obligations and to create, preserve, maintain and
perfect the Liens of the Administrative Agent for the benefit of itself and the
Lenders in and to the Collateral and the required priority of such Liens. Each
of the Loan Parties will make available to the Administrative Agent appropriate
personnel reasonably necessary to discuss the Business Plan and any updates

         Section 8.12 Interest Rate Protection. The Borrower will, commencing
on or before the thirtieth (30th) day after the Closing Date, maintain in full
force and effect through the Maturity Date one or more Interest Rate Protection

reasonably acceptable to the Administrative Agent, which Lenders or Affiliates
or other counterparties shall in each case be rated in one of the two of the
highest rating categories of Standard & Poors Corporation or Moody's Investors

with respect to not less than an aggregate notational amount (not less than
zero) equal to fifty percent (50%) of the aggregate principal amount of the
Total Debt that does not have a fixed interest rate.

         Section 8.13 Sprint Agreements. Each of the Loan Parties will comply
with all provisions of each Sprint Agreement except to the extent that such

         Section 8.15 Year 2000 Compliance. Except as may be set forth in
Schedule 8.15 and except for instances of noncompliance that the Borrower
believes could not, individually or in the aggregate, reasonably be expected to
cause a Material Adverse Effect, each of the Loan Parties will take
commercially reasonable efforts to determine that all of the material computer

         Section 12.1 Appointment, Powers and Immunities. Each Lender hereby
irrevocably appoints and authorizes the Administrative Agent to act as its
agent hereunder and under the other Loan Documents with such powers as are
specifically delegated to the Administrative Agent by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto. Neither the Administrative Agent nor any of its
Affiliates, officers, directors, employees, attorneys or agents shall be liable
for any action taken or omitted to be taken by any of them hereunder or
otherwise in connection with this Agreement or any of the other Loan Documents
except for its or their own gross negligence or willful misconduct. Without
limiting the generality of the preceding sentence, the Administrative Agent (a)
may treat the payee of any Note as the holder thereof until the Administrative
Agent receives written notice of the assignment or transfer thereof signed by
such payee and in form satisfactory to the Administrative Agent, (b) shall have
no duties or responsibilities except those expressly set forth in this
Agreement and the other Loan Documents, and shall not by reason of this
Agreement or any other Loan Document be a trustee or fiduciary for any Lender,
(c) shall not be required to initiate any litigation or collection proceedings
hereunder or under any other Loan Document except to the extent requested by
the Required Lenders, (d) shall not be responsible to the Lenders for any
recitals, statements, representations or warranties contained in this Agreement
or any other Loan Document, or any certificate or other document referred to or
provided for in, or received by any of them under, this


CREDIT AGREEMENT - Page 93



<PAGE>   101



Agreement or any other Loan Document, or for the value, validity,
effectiveness, enforceability or sufficiency of this Agreement or any other
Loan Document or any other document referred to or provided for herein or
therein or for any failure by any Person to perform any of its obligations
hereunder or thereunder, (e) may consult with legal counsel (including counsel
for any Loan Party), independent public accountants and other experts selected
by it and shall not be liable for any action taken or omitted to be taken in
good faith by it in accordance with the advice of such counsel, accountants or
experts, and (f) shall incur no liability under or in respect of any Loan
Document by acting upon any notice, consent, certificate or other instrument or
writing reasonably believed by it to be genuine and signed or sent by the
proper party or parties. As to any matters not expressly provided for by this
Agreement, the Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, hereunder in accordance with instructions
signed by the Required Lenders, and such instructions of the Required Lenders
and any action taken or failure to act pursuant thereto shall be binding on all
of the Lenders; provided, however, that the Administrative Agent shall not be
required to take any action which exposes the Administrative Agent to liability
or which is contrary to this Agreement or any other Loan Document or applicable
law. The Administrative Agent shall not be deemed to have any fiduciary
relationship with any Lender or any Loan Party, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or otherwise exist against the Administrative Agent.
Without limiting the generality of the foregoing, the use of the term "agent"
in this Agreement with respect to the Administrative Agent is not intended to
connote any fiduciary or other express or implied obligation arising under
agency doctrine of any applicable law; instead, such term is used merely as a
matter of market custom and is intended to create or reflect only an
administrative relationship among independent contracting parties.

         Section 12.2 Rights of Administrative Agent as a Lender. With respect
to its Commitments, the Loans made by it and the Note(s) issued to it, Nortel
Networks (and any successor acting as Administrative Agent) in its capacity as
a Lender hereunder shall have the same rights and powers hereunder as any other
Lender and may exercise the same as though it were not acting as the
Administrative Agent, and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include the Administrative Agent in its individual
capacity. The Administrative Agent and its Affiliates may (without having to
account therefor to any Lender) accept deposits from, lend money to, act as
trustee under indentures of, provide merchant banking services to, own
securities of, and generally engage in any kind of banking, trust or other
business with, any Loan Party or any of its Affiliates and any other Person who
may do business with or own securities of any Loan Party or any of its
Affiliates, all as if it were not acting as the Administrative Agent and
without any duty to account therefor to the Lenders. Without limiting the
generality of the foregoing, it is contemplated that (a) Nortel Networks will
be the holder of the warrants issued by Holdings and (b) Nortel Networks and/or
an Affiliate of Nortel Networks may purchase equity securities of Holdings.

         Section 12.3 Defaults. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of a Default (other than the
non-payment of principal of or interest on the Loans or of commitment fees)
unless the Administrative Agent has received notice from a Lender or the
Borrower specifying such Default and stating that such notice is a "notice of
default". In the event that the Administrative Agent receives such a notice of
the occurrence of a Default, the Administrative Agent shall give prompt notice
thereof to the Lenders (and shall give each Lender


CREDIT AGREEMENT - Page 94



<PAGE>   102



prompt notice of each such non-payment). The Administrative Agent shall
(subject to Section 12.1) take such action with respect to such Default as
shall be directed by the Required Lenders, provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default as it shall seem advisable and
in the best interest of the Lenders.

         SECTION 12.4 INDEMNIFICATION. EACH LENDER HEREBY AGREES TO INDEMNIFY
THE ADMINISTRATIVE AGENT FROM AND HOLD THE ADMINISTRATIVE AGENT HARMLESS
AGAINST (TO THE EXTENT NOT REIMBURSED UNDER SECTIONS 13.1 AND 13.2, BUT WITHOUT
LIMITING THE OBLIGATIONS OF THE BORROWER UNDER SECTIONS 13.1 AND 13.2), RATABLY
IN ACCORDANCE WITH ITS PRO RATA SHARE (CALCULATED ON THE BASIS OF ITS
COMMITMENT PERCENTAGE OF THE AGGREGATE COMMITMENTS), ANY AND ALL LIABILITIES
(INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL LIABILITIES), OBLIGATIONS,
LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, DEFICIENCIES, SUITS, COSTS,
EXPENSES (INCLUDING ATTORNEYS' FEES) AND DISBURSEMENTS OF ANY KIND OR NATURE
WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE
ADMINISTRATIVE AGENT IN ANY WAY RELATING TO OR ARISING OUT OF ANY OF THE LOAN
DOCUMENTS OR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY THE ADMINISTRATIVE
AGENT UNDER OR IN RESPECT OF ANY OF THE LOAN DOCUMENTS; PROVIDED, THAT NO
LENDER SHALL BE LIABLE FOR ANY PORTION OF THE FOREGOING TO THE EXTENT CAUSED BY
THE ADMINISTRATIVE AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. WITHOUT
LIMITATION OF THE FOREGOING, IT IS THE EXPRESS INTENTION OF THE LENDERS THAT
THE ADMINISTRATIVE AGENT SHALL BE INDEMNIFIED HEREUNDER FROM AND HELD HARMLESS
AGAINST ALL OF SUCH LIABILITIES (INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL
LIABILITIES), OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
DEFICIENCIES, SUITS, COSTS, EXPENSES (INCLUDING ATTORNEYS' FEES) AND
DISBURSEMENTS OF ANY KIND OR NATURE DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF THE ADMINISTRATIVE AGENT
(EXCEPT TO THE EXTENT THE SAME ARE CAUSED BY THE ADMINISTRATIVE AGENT'S GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT). WITHOUT LIMITING ANY OTHER PROVISION OF THIS
SECTION 12.4, EACH LENDER AGREES TO REIMBURSE THE ADMINISTRATIVE AGENT PROMPTLY
UPON DEMAND FOR ITS PRO RATA SHARE (CALCULATED ON THE BASIS OF ITS COMMITMENT
PERCENTAGE OF THE AGGREGATE COMMITMENTS) OF ANY AND ALL OUT-OF-POCKET EXPENSES
(INCLUDING ATTORNEYS' FEES) INCURRED BY THE ADMINISTRATIVE AGENT IN CONNECTION
WITH THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION, MODIFICATION,
AMENDMENT OR ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, LEGAL PROCEEDINGS OR
OTHERWISE) OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER,
THE


CREDIT AGREEMENT - Page 95



<PAGE>   103



LOAN DOCUMENTS, TO THE EXTENT THAT THE ADMINISTRATIVE AGENT IS NOT PROMPTLY
REIMBURSED FOR SUCH EXPENSES BY THE BORROWER.

         Section 12.5 Independent Credit Decisions. Each Lender agrees that it
has independently and without reliance on the Administrative Agent or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of the Borrower and the other Loan
Parties and its own decision to enter into this Agreement and that it will,
independently and without reliance upon the Administrative Agent or any other
Lender, and based upon such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this Agreement or any of the other Loan
Documents. The Administrative Agent shall not be required to keep itself
informed as to the performance or observance by any Loan Party of this
Agreement or any other Loan Document or to inspect the Properties or books of
any Loan Party (or any other Person). Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
the Administrative Agent hereunder or under the other Loan Documents, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other financial information concerning the affairs,
financial condition or business of any Loan Party which may come into the
possession of the Administrative Agent or any of its Affiliates.

         Section 12.6 Several Commitments. The Commitments and other
obligations of the Lenders under this Agreement are several. The default by any
Lender in making a Loan in accordance with any of its Commitments shall not
relieve the other Lenders of their obligations under this Agreement. In the
event of any default by any Lender in making any Loan, each nondefaulting
Lender shall be obligated to make its Loan but shall not be obligated to
advance the amount which the defaulting Lender was required to advance
hereunder. In no event shall any Lender be required to advance an amount or
amounts with respect to any of the Loans which would in the aggregate exceed
such Lender's Commitment with respect to such Loans. No Lender shall be
responsible for any act or omission of any other Lender.

         Section 12.7 Successor Administrative Agent. Subject to the
appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by giving notice thereof
to the Lenders and the Borrower. Upon any such resignation, the Required
Lenders will have the right to appoint another Lender as a successor
Administrative Agent. If no successor Administrative Agent shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within 30 days after the retiring Administrative Agent's giving of notice of
resignation, then the retiring Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent, which shall be a commercial
bank organized under the laws of the U.S. or any state thereof or of a foreign
country if acting through its U.S. branch and having combined capital and
surplus of at least $100,000,000. Upon the acceptance of its appointment as
successor Administrative Agent, such successor Administrative Agent shall
thereupon succeed to and become vested with all rights, powers, privileges,
immunities and duties of the resigning Administrative Agent, and the resigning
Administrative Agent shall be discharged from its duties and obligations under
this Agreement and the other Loan Documents. After any Administrative Agent's
resignation as Administrative Agent, the provisions of this Article 12 shall
continue in effect for its benefit in respect of any actions taken or omitted
to be taken by it while it was the


CREDIT AGREEMENT - Page 96



<PAGE>   104



Administrative Agent. Each Administrative Agent (including each successor
Administrative Agent) agrees that, so long as it is acting as Administrative
Agent under this Agreement, it shall be a Lender under this Agreement.


                                   ARTICLE 13

                                 Miscellaneous

         Section 13.1 Expenses. The Borrower hereby agrees, on demand, to pay
or reimburse the Administrative Agent and each of the Lenders for paying: (a)
all reasonable out-of-pocket costs and expenses of the Administrative Agent
accrued in connection with the drafting, preparation, negotiation, execution
and/or delivery of this Agreement and the other Loan Documents, and any and all
waivers, amendments, modifications, renewals, extensions and supplements of or
to the Loan Documents, and the syndication of the Commitments and the Loans,
including, without limitation, the reasonable fees and expenses of legal
counsel (including all local counsel) for the Administrative Agent, (b) all
out-of-pocket costs and expenses of the Administrative Agent and the Lenders in
connection with any Default, the exercise of any right or remedy and the
enforcement of this Agreement or any other Loan Document or any term or
provision hereof or thereof, including, without limitation, the fees and
expenses of all legal counsel for the Administrative Agent and/or any Lender,
(c) all transfer, stamp, documentary or other similar taxes, assessments or
charges levied by any Governmental Authority in respect of this Agreement or
any of the other Loan Documents, (d) all costs, expenses, assessments and other
charges incurred in connection with any filing, registration, recording or
perfection of any Lien contemplated by this Agreement or any other Loan
Document, and (e) all reasonable out-of-pocket costs and expenses incurred by
the Administrative Agent in connection with due diligence, computer services,
copying, appraisals, environmental audits, collateral audits, field exams,
insurance, consultants and search reports. Notwithstanding the foregoing
provisions of this Section 13.1, the legal fees and related expenses of counsel
to the Administrative Agent shall be subject to the limitations therefor
specified in the Administrative Agent's Letter.

         SECTION 13.2 INDEMNIFICATION. EACH OF THE LOAN PARTIES HEREBY JOINTLY
AND SEVERALLY AGREES TO INDEMNIFY THE ADMINISTRATIVE AGENT AND EACH LENDER AND
EACH AFFILIATE THEREOF AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES,
ATTORNEYS AND AGENTS FROM, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL
LOSSES, LIABILITIES (INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL LIABILITIES),
CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS AND EXPENSES
(INCLUDING REASONABLE ATTORNEYS' AND CONSULTANTS' FEES) TO WHICH ANY OF THEM
MAY BECOME SUBJECT WHICH DIRECTLY OR INDIRECTLY ARISE FROM OR RELATE TO (A) THE
NEGOTIATION, EXECUTION, DELIVERY, PERFORMANCE, ADMINISTRATION OR ENFORCEMENT OF
ANY OF THE LOAN DOCUMENTS, INCLUDING, WITHOUT LIMITATION, THE EXERCISE OF ANY
FORECLOSURE RIGHT OR OTHER RIGHT OR REMEDY WHETHER OR NOT SUCH EXERCISE IS IN
COMPLIANCE WITH LAWS AFFECTING OTHER PERSONS OR RESULTS IN DAMAGES PAYABLE TO
OTHER PERSONS, (B)


CREDIT AGREEMENT - Page 97



<PAGE>   105



ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS, (C) ANY BREACH BY
ANY LOAN PARTY OF ANY MATERIAL REPRESENTATION, WARRANTY, COVENANT OR OTHER
AGREEMENT CONTAINED IN ANY OF THE LOAN DOCUMENTS, (D) THE USE OR PROPOSED USE
OF ANY LOAN, (E) THE PRESENCE, RELEASE, THREATENED RELEASE, DISPOSAL, REMOVAL
OR CLEANUP OF ANY HAZARDOUS MATERIAL LOCATED ON, ABOUT, WITHIN OR AFFECTING ANY
OF THE PROPERTIES OF ANY LOAN PARTY OR ANY OF THEIR AFFILIATES, EXCEPT TO THE
EXTENT THAT THE LOSS, DAMAGE OR CLAIM IS THE DIRECT RESULT OF GROSS NEGLIGENCE
OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED, OR (F) ANY
INVESTIGATION, LITIGATION OR OTHER PROCEEDING, INCLUDING, WITHOUT LIMITATION,
ANY THREATENED INVESTIGATION, LITIGATION OR OTHER PROCEEDING RELATING TO ANY OF
THE FOREGOING; BUT EXCLUDING ANY OF THE FOREGOING TO THE EXTENT CAUSED BY THE
GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED. WITHOUT
LIMITING ANY PROVISION OF THIS AGREEMENT OR OF ANY OTHER LOAN DOCUMENT, IT IS
THE EXPRESS INTENTION OF THE PARTIES HERETO THAT EACH PERSON TO BE INDEMNIFIED
UNDER THIS SECTION 13.2 SHALL BE INDEMNIFIED FROM AND HELD HARMLESS AGAINST ANY
AND ALL LOSSES, LIABILITIES (INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL
LIABILITIES), CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, DISBURSEMENTS, COSTS AND
EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES) ARISING OUT OF OR RESULTING
FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH PERSON. WITHOUT PREJUDICE TO
THE SURVIVAL OF ANY OTHER TERM OR PROVISION OF THIS AGREEMENT, THE OBLIGATIONS
OF THE LOAN PARTIES UNDER THIS SECTION 13.2 SHALL SURVIVE THE REPAYMENT OF THE
LOANS AND OTHER OBLIGATIONS AND TERMINATION OF THE COMMITMENTS.

         Section 13.3 Limitation of Liability. None of the Administrative
Agent, any Lender or any Affiliate, officer, director, employee, attorney or
agent thereof shall be liable for any error of judgment or act done in good
faith, or be otherwise liable or responsible under any circumstances whatsoever
(including such Person's negligence), except for such Person's gross negligence
or willful misconduct. None of the Administrative Agent, any Lender or any
Affiliate, officer, director, employee, attorney or agent thereof shall have
any liability with respect to, and each of the Borrower and the other Loan
Parties hereby waives, releases and agrees not to sue any of them upon, any
claim for any special, indirect, incidental or consequential damages suffered
or incurred by any Loan Party or any of its Affiliates in connection with,
arising out of or in any way related to this Agreement or any of the other Loan
Documents, or any of the transactions contemplated by this Agreement or any of
the other Loan Documents. Each of the Loan Parties hereby waives, releases and
agrees not to sue the Administrative Agent or any Lender or any of their
respective Affiliates, officers, directors, employees, attorneys or agents for
exemplary or punitive damages in respect of any claim in connection with,
arising out of or in any way related to this Agreement or any of the other Loan
Documents, or any of the transactions contemplated by this Agreement or any of
the other Loan Documents.


CREDIT AGREEMENT - Page 98



<PAGE>   106



         Section 13.4 No Duty. All attorneys, accountants, appraisers and other
professional Persons and consultants retained by the Administrative Agent and
the Lenders shall have the right to act exclusively in the interest of the
Administrative Agent and the Lenders and shall have no duty of disclosure, duty
of loyalty, duty of care or other duty or obligation of any type or nature
whatsoever to any Loan Party or any of its Affiliates or any other Person.

         Section 13.5 No Fiduciary Relationship. The relationship between each
Loan Party and each Lender is solely that of debtor and creditor, and neither
the Administrative Agent nor any Lender has any fiduciary or other special
relationship with any Loan Party or any of its Affiliates, and no term or
condition of any of the Loan Documents shall be construed so as to deem the
relationship between any Loan Party and any Lender, or such Affiliate and any
Lender, to be other than that of debtor and creditor. No joint venture or
partnership is created by this Agreement among the Lenders or among any Loan
Party or any of its Affiliates and the Lenders.

         Section 13.6 Equitable Relief. Each of the Loan Parties recognizes
that, in the event it fails to pay, perform, observe or discharge any or all of
the Obligations, any remedy at law may prove to be inadequate relief to the
Administrative Agent and the Lenders. Each of the Loan Parties therefore agrees
that the Administrative Agent and the Lenders, if the Administrative Agent or
the Lenders so request, shall be entitled to temporary and permanent injunctive
relief in any such case without the necessity of proving actual damages.

         Section 13.7 No Waiver; Cumulative Remedies. No failure on the part of
the Administrative Agent or any Lender to exercise and no delay in exercising,
and no course of dealing with respect to, any right, power or privilege under
this Agreement or any other Loan Document shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, power or privilege under
this Agreement or any other Loan Document preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The
rights and remedies provided for in this Agreement and the other Loan Documents
are cumulative and not exclusive of any rights and remedies provided by law.

         Section 13.8 Successors and Assigns.

         (a) This Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns. Neither the
Borrower nor any other Loan Party may assign or transfer any of its rights or
obligations under this Agreement or any other Loan Document without the prior
written consent of the Administrative Agent and the Lenders. Any Lender may
sell participations in all or a portion of its rights and obligations under
this Agreement and the other Loan Documents (including, without limitation, all
or a portion of its Commitments and the Loans owing to it); provided, however,
that (i) such Lender's obligations under this Agreement and the other Loan
Documents (including, without limitation, its Commitments) shall remain
unchanged, (ii) such Lender shall remain solely responsible to the Borrower for
the performance of such obligations, (iii) such Lender shall remain the holder
of its Notes for all purposes of this Agreement, (iv) the Borrower shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement and the other Loan
Documents, and (v) the Lenders shall not grant any participation under which
the participant shall have the right to approve


CREDIT AGREEMENT - Page 99



<PAGE>   107



(or under which the consent of the participant must be obtained prior to the
Lenders' being able to approve) any amendment or waiver of this Agreement or
the other Loan Documents, except to the extent that such amendment or waiver
(A) increases any Commitment, (B) reduces the interest rate or the amount of
principal or fees applicable to the Loans or Commitments in which such
participant is participating, (C) extends any Maturity Date, (D) releases any
of the Collateral (except as provided for herein or in any other Loan Document)
or any guaranty of the Obligations, or (E) releases any Loan Party from its
monetary Obligations under any of the Loan Documents.

         (b) The Loan Parties and each of the Lenders agree that any Lender
(the "Assigning Lender") may at any time assign to one or more Eligible
Assignees all or any part of its rights and/or obligations under this Agreement
and the other Loan Documents (including, without limitation, its Commitments
and/or Loans) (each an "Assignee"); provided, however, that (i) each such
assignment may be of a varying percentage of the Assigning Lender's rights
and/or obligations under this Agreement and the other Loan Documents and may
relate to some but not all of such rights and/or obligations, (ii) except in
the case of (A) an assignment of all of a Lender's rights and obligations under
this Agreement and the other Loan Documents or (B) an assignment by a Lender to
an Affiliate of such Lender, to another Lender or to an Approved Fund, the
amount of the Commitment(s) and/or Loans of the Assigning Lender being assigned
pursuant to each assignment (determined as of the date of the Assignment and
Acceptance with respect to such assignment) shall in no event be less than
$5,000,000 calculated based upon the aggregate amount of the Commitment(s)
and/or Loans assigned and (iii) the parties to each such assignment shall
execute and deliver to the Administrative Agent for its acceptance and
recording in the Register (as defined below), an Assignment and Acceptance,
together with the Note subject to such assignment, and a processing and
recordation fee of $3,500. Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in each Assignment and
Acceptance, which effective date shall be at least five Business Days after the
execution thereof or such other date as may be approved by the Administrative
Agent, (1) the Assignee thereunder shall be a party hereto as a "Lender" and,
to the extent that rights and obligations hereunder have been assigned to it
pursuant to such Assignment and Acceptance, have the rights and obligations of
a Lender hereunder and under the other Loan Documents, and (2) the Assigning
Lender thereunder shall, to the extent that rights and obligations hereunder
have been assigned by it pursuant to such Assignment and Acceptance, relinquish
its rights and be released from its obligations under this Agreement and the
other Loan Documents (and, in the case of an Assignment and Acceptance covering
all or the remaining portion of a Lender's rights and obligations under the
Loan Documents, such Lender shall cease to be a party thereto, provided that
such Lender's rights under Article 4, Section 13.1 and Section 13.2 accrued
through the date of assignment shall continue). Holdings and the Borrower will
provide full and prompt assistance to each Lender as it may reasonably request
from time to time in connection with such Lender's efforts to assign its
Commitments and/or Loans or sell any participation interest therein. Such
assistance shall include, without limitation, making senior officers of
Holdings and the Borrower available for meetings with prospective Lenders and
participants and providing (in a timely manner) such assistance as may be
reasonably requested by such Lender and/or its advisors, including, without
limitation, providing information to and responding to inquiries from such
prospective Lenders and participants with respect to the businesses,
operations, business plan, financial condition and results of operations of the
Loan Parties.


CREDIT AGREEMENT - Page 100



<PAGE>   108



         (c) By executing and delivering an Assignment and Acceptance, the
Assigning Lender thereunder and the Assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such Assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with the
Loan Documents or the execution, legality, validity, enforceability,
genuineness, sufficiency or value of the Loan Documents or any other instrument
or document furnished pursuant thereto; (ii) such Assigning Lender makes no
representation or warranty and assumes no responsibility with respect to the
financial condition or results of operations of any Loan Party or any of its
Affiliates or the performance or observance by any Loan Party or any of its
Affiliates of its obligations under the Loan Documents; (iii) such Assignee
confirms that it has received a copy of the Loan Documents, together with
copies of the financial statements referred to in Section 7.2 and such other
documents and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment and Acceptance; (iv) such
Assignee will, independently and without reliance upon the Administrative Agent
or such Assigning Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement and the other Loan
Documents; (v) such Assignee confirms that it is an Eligible Assignee; (vi)
such Assignee appoints and authorizes the Administrative Agent to take such
action as agent on its behalf and exercise such powers under the Loan Documents
as are delegated to the Administrative Agent by the terms thereof, together
with such powers as are reasonably incidental thereto; and (vii) such Assignee
agrees that it will perform in accordance with their terms all of the
obligations which by the terms of the Loan Documents are required to be
performed by it as a Lender.

         (d) The Administrative Agent shall maintain at its Principal Office a
copy of each Assignment and Acceptance delivered to and accepted by it and a
register for the recordation of the names and addresses of the Lenders and the
Commitments of, and principal amount of the Loans owing to, each Lender from
time to time (the "Register"). The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and the Loan Parties, the
Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register as a Lender hereunder for all purposes under the Loan
Documents. The Register shall be available for inspection by the Borrower or
any Lender at any reasonable time and from time to time upon reasonable prior
notice.

         (e) Upon its receipt of an Assignment and Acceptance executed by an
Assigning Lender and Assignee representing that it is an Eligible Assignee,
together with the Note(s) subject to such assignment, the Administrative Agent
shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit A hereto, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register, and
(iii) give prompt written notice thereof to the Borrower. Within five Business
Days after its receipt of such notice, the Borrower, at its expense, shall
execute and deliver to the Administrative Agent in exchange for each
surrendered Note evidencing the Loans assigned, a new Note evidencing such
Loans payable to the order of such Eligible Assignee in an amount equal to such
Loans assigned to it and, if the Assigning Lender has retained any Loans, a new
Note evidencing each such Loans payable to the order of the Assigning Lender in
the amount of such Loans retained by it (each such promissory note shall
constitute a


CREDIT AGREEMENT - Page 101



<PAGE>   109



"Note" for purposes of the Loan Documents). Such new Notes shall be dated the
effective date of such Assignment and Acceptance and shall otherwise be in
substantially the form of Exhibit B hereto.

         (f) Any Lender may, in connection with any assignment or participation
or proposed assignment or participation pursuant to this Section 13.8, disclose
to the Assignee or participant or proposed Assignee or participant any
information relating to any Loan Party or any of its Affiliates furnished to
such Lender by or on behalf of the any Loan Party or any of its Affiliates;
provided that each such actual or proposed Assignee or participant shall agree
to be bound by the provisions of Section 13.20.

         (g) Any Lender may assign and pledge any Note held by it to any
Federal Reserve Bank or the U.S. Treasury as collateral security pursuant to
Regulation A of the Board of Governors of the Federal Reserve System and any
operating circular issued by such Federal Reserve System and/or Federal Reserve
Bank; provided, however, that any payment made by the Borrower for the benefit
of such assigning and/or pledging Lender in accordance with the terms of the
Loan Documents shall satisfy the Borrower's obligations under the Loan
Documents in respect thereof to the extent of such payment. No such assignment
and/or pledge shall release the assigning and/or pledging Lender from its
obligations hereunder.

         (h) The Borrower shall maintain, or cause to be maintained, a register
(the "Registered Note Register") (which, at the request of the Borrower (which
request the Borrower makes by the execution of this Agreement) shall be kept by
the Administrative Agent on behalf of the Borrower at no extra charge to the
Borrower at the address to which notices to the Administrative Agent are to be
sent hereunder) on which it shall enter the name of the registered owner of
each of the Loans which is evidenced by a Registered Note. Notwithstanding
anything to the contrary contained in this Section 13.8, a Registered Note and
the Loans evidenced thereby may be assigned or otherwise transferred in whole
or in part only by registration of such assignment or transfer of such
Registered Note and the Loans evidenced thereby on the Registered Note Register
(and each Registered Note shall expressly so provide). Any assignment or
transfer of all or part of such Loans and the Registered Note evidencing the
same shall be registered on the Registered Note Register only upon surrender
for registration of assignment or transfer of the Registered Note evidencing
such Loans, duly endorsed by (or accompanied by a written instrument of
assignment or transfer duly executed by) the registered noteholder thereof, and
thereupon one or more new Registered Notes in the same aggregate principal
amount shall be issued to the designated assignee(s) or transferee(s). Prior to
the due presentment for registration of transfer of any Registered Note, the
Borrower and the Administrative Agent shall treat the Person in whose name such
Loans and the Registered Note(s) evidencing the same are registered as the
owner thereof for the purpose of receiving all payments thereon and for all
other purposes, notwithstanding any notice to the contrary. The Registered Note

         (j) Holdings and the Borrower shall provide prompt assistance to the
Administrative Agent and the Lenders in connection with their respective
efforts in syndicating the Loans and Commitments. Such assistance shall include
making senior officers and other representatives of Holdings and the Borrower
and their Affiliates available for meetings with prospective Lenders and
providing, in a timely manner, such assistance as may be reasonably requested

Administrative Agent or any Lender or any closing shall affect the

Lender to rely upon them. Without prejudice to the survival of any other
obligation of any of the Loan Parties hereunder or under the other Loan
Documents, the obligations of the Borrower and the other Loan Parties under
Article 4 and Sections 13.1 and 13.2 shall survive repayment of the Loans and
the Reimbursement Obligations and the other Obligations.

         SECTION 13.10 ENTIRE AGREEMENT. THIS AGREEMENT, THE NOTES AND THE
OTHER LOAN DOCUMENTS REFERRED TO HEREIN EMBODY THE FINAL, ENTIRE AGREEMENT

this Agreement, the Notes or any other Loan Document to which any Loan Party is
a party, nor any consent to any departure by any Loan Party therefrom, shall in
any event be effective unless the same shall be agreed or consented to by the
Required Lenders and such Loan Party in writing, and each such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given; provided, however, that no amendment, waiver or
consent shall, unless in writing and signed by all of the Lenders and the
Borrower, do any of the following: (a) increase the Commitments of the Lenders
(or any Lender) or subject the Lenders to any additional obligations; (b)

or 5.1 or this Section 13.11 or modify the definition of "Required Lenders," or
"Permitted Third- Party Expenses Borrowing Base" contained in Section 1.1; or
(f) except as expressly authorized by this Agreement, release any Collateral
from any of the Liens created by the Security Documents; and provided further,
however, that no amendment, waiver or consent relating to Sections 12.1, 12.2,
12.3, 12.4 or 12.5 shall require the agreement of the Borrower or any other
Loan Party. Notwithstanding anything to the contrary contained in this Section
13.11, no amendment, waiver or consent shall be made with respect to (i)
Article 12 hereof without the prior written consent of the Administrative
Agent, (ii) the definitions of "Nortel Networks Equipment", "Nortel Networks
Goods and Services", "Nortel Networks Software", "Permitted Third-Party
Expenses", "Permitted Third-Party Expenses Borrowing Base", "Supply Agreement"
or Section 2.5, 2.9 or 2.10 hereof without the prior written consent of Nortel
Networks (whether or not Nortel Networks is then a Lender hereunder), or (iii)
any condition precedent set forth in Article 6 with respect to the making of
any Tranche A Loans, Tranche B Loans or Tranche C Loans without the prior
written consent of the Lenders that hold, at the time of such amendment, waiver
or consent, at least a majority (in Dollar amount) of the Tranche A
Commitments, Tranche B Commitments or Tranche C Commitments, respectively.

         Section 13.12 Maximum Interest Rate.


         (a) No interest rate specified in this Agreement or any other Loan
Document shall at any time exceed the Maximum Rate. If at any time the interest
rate (the "Contract Rate") for any Obligation shall exceed the Maximum Rate,
thereby causing the interest accruing on such Obligation to be limited to the
Maximum Rate, then any subsequent reduction in the Contract Rate for such
Obligation shall not reduce the rate of interest on such Obligation below the
Maximum Rate until the aggregate amount of interest accrued on such Obligation
equals the aggregate amount of interest which would have accrued on such
Obligation if the Contract Rate for such Obligation had at all times been in
effect.

         (b) Notwithstanding anything to the contrary contained in this
Agreement or the other Loan Documents, none of the terms and provisions of this
Agreement or the other Loan Documents shall ever be construed to create a
contract or obligation to pay interest at a rate in excess of the Maximum Rate;
and neither the Administrative Agent nor any Lender shall ever charge, receive,
take, collect, reserve or apply, as interest on the Obligations, any amount in
excess of the Maximum Rate. The parties hereto agree that any interest, charge,
fee, expense or other obligation provided for in this Agreement or in the other
Loan Documents which constitutes interest under applicable law shall be, ipso
facto and under any and all circumstances, limited or reduced to an amount
equal to the lesser of (i) the amount of such interest, charge, fee, expense or
other obligation that would be payable in the absence of this Section 13.12(b)
or (ii) an amount, which when added to all other interest payable under this
Agreement and the other Loan Documents, equals the Maximum Rate. If,
notwithstanding the foregoing, the Administrative Agent or any Lender ever
contracts for, charges, receives, takes, collects, reserves or applies as
interest any amount in excess of the Maximum Rate, such amount which would be
deemed excessive interest shall be deemed a partial payment or prepayment of
principal of the Obligations and treated hereunder as such; and if the
Obligations, or applicable portions thereof, are paid in full, any remaining
excess shall promptly be paid to the Borrower. In determining whether the
interest paid or payable, under any specific


CREDIT AGREEMENT - Page 104



<PAGE>   112



contingency, exceeds the Maximum Rate, the Borrower and the other Loan Parties,
the Administrative Agent and the Lenders shall, to the maximum extent permitted
by applicable law, (i) characterize any nonprincipal payment as an expense, fee
or premium rather than as interest, (ii) exclude voluntary prepayments and the
effects thereof, and (iii) amortize, prorate, allocate and spread in equal or
unequal parts the total amount of interest throughout the entire contemplated
term of the Obligations, or applicable portions thereof, so that the interest
rate does not exceed the Maximum Rate at any time during the term of the
Obligations; provided that, if the unpaid principal balance is paid and
performed in full prior to the end of the full contemplated term thereof, and
if the interest received for the actual period of existence thereof exceeds the
Maximum Rate, the Administrative Agent and/or the Lenders, as appropriate,
shall refund to the Borrower the amount of such excess and, in such event, the
Administrative Agent and the Lenders shall not be subject to any penalties
provided by any laws for contracting for, charging, receiving, taking,
collecting, reserving or applying interest in excess of the Maximum Rate.

         Section 13.13 Notices. All notices and other communications provided

be given independent effect so that if a particular action or condition is not
permitted by any of such covenants, the fact that it would be permitted by an

exists.

         Section 13.20 Confidentiality.

         (a) Lenders' Obligations. Each Lender agrees to exercise its best
efforts to keep any information delivered or made available by the Borrower to
it which is clearly indicated to be confidential information, confidential from
anyone other than Persons employed or retained by such Lender who are or are

                                 AMENDMENT NO. 4
                                       TO

                              NORTEL NETWORKS INC.

        This Amendment No. 4 is made effective as of the 8th day of February,
2000, by and between Nortel Networks Inc. (successor in interest to Northern

Services ("Agreement"); and

        WHEREAS, Buyer and Seller now wish to, among other things, amend the
Agreement to extend the Term and adjust Buyer's Volume Commitment; and

        NOW, THEREFORE, in consideration of the mutual covenants herein
contained, Buyer and Seller hereby agree to amend the Agreement as follows:

        1.  Amend Article 1 (Definitions), Section 1.46 by deleting the phrase
            "three years therefrom" and replacing it with "on July 1, 2002."

        2.  Amend Section 5.3 by deleting the reference to "eighty-two million
            dollars ($82,000,000) and replacing it with "one hundred sixty-seven
            million dollars ($167,000,000)."

        3.  Amend Section 5.4 by deleting the section in its entirety and
            replacing it with the following:

            "5.4  Until Buyer's total purchases under this Agreement exceed
                  eighty-two million dollars ($82,000,000) net Price in
                  Equipment and Services, such Equipment and Services purchased
                  and financed by Seller shall be subject to an additional three
                  percent (3%) financing premium ("Financing Premium") over the
                  Additional Affiliate pricing as set forth in Annex 1. For

                  Services in excess of eighty-two million dollars [$82,000,000]
                  net Price), such Financing Premium shall no longer apply."

        4.  Except as specifically modified herein, the Agreement in all other
            respects shall continue in full force and effect.

               AMENDED AND RESTATED MASTER DESIGN BUILD AGREEMENT


     THIS AMENDED AND RESTATED MASTER DESIGN BUILD AGREEMENT ("AGREEMENT"),
dated as of the 21st day of March, 2000 is made by and between Texas
Telecommunications, L.P., a Texas limited partnership and Alamosa Wisconsin
Limited Partnership, a Wisconsin limited partnership (collectively, "CARRIER")
and SBA Towers, Inc., a Florida corporation ("BTS COMPANY").

     WHEREAS, Carrier and BTS Company entered into a Master Design Build
Agreement, dated as of February 22, 2000 (the "EXISTING MASTER DESIGN BUILD
AGREEMENT"); and

     WHEREAS, Carrier and BTS Company have agreed to amend and restate the
Existing Master Design Build Agreement to make certain changes, including the
addition of confidentiality provisions, on the terms and conditions set forth
herein;

     NOW, THEREFORE, in consideration of the mutual promises set forth herein,
the parties hereto agree that on the date set forth above, the Existing Master
Design Build Agreement shall be amended and restated in its entirety as follows:

                           I. RELATIONSHIP OF PARTIES

     1.1 INDEPENDENT CONTRACTOR RELATIONSHIP. The parties intend by this
Agreement to establish an independent contractor relationship. Neither party
nor their employees shall be agents or legal representatives of the other party
for any purpose. Neither party shall have the authority to act for, bind, or
commit the other party. BTS Company and Carrier agree that this Agreement does
not establish or create a relationship of employer-employee, principal-agent, or
a franchise, joint venture, or partnership for any purpose whatsoever.

     1.2 CONTRACTS WITH AFFILIATES. BTS Company may contract with any Affiliate
(as hereinafter defined) of BTS Company to provide goods or services beyond
those which its employees would perform, if it deems the same to be necessary or
advisable for development and/or construction of the Sites (as hereinafter
defined).

     1.3 LANDLORD AND TENANT RELATIONSHIP. BTS Company and Carrier have executed
the Master Site Agreement ("MSA"), dated as of February 22, 2000, which governs
the relationship of BTS Company, as landlord, and Carrier, as tenant, on those
BTS Sites (as hereinafter defined) which are accepted by Carrier pursuant to
SECTION 2.7(b) of this Agreement. A copy of the MSA is attached hereto as
EXHIBIT A. BTS Company and Carrier shall execute a Site Lease Agreement ("SLA")
with respect to each BTS Site in accordance with SECTION 2.7. The parties agree
to cooperate and act reasonably while performing under this Agreement, the MSA
and all SLAs.

     1.4 EXCLUSIVITY. During the term of this Agreement, BTS Company shall be
the exclusive build-to-suit service provider, site acquisition service provider,
line and antenna installation provider (except as to structural collocations
that are installed on a structure that is not a tower or in an instance where a
collocation tower owner requires the use of a designated contractor for
installation of Carrier's equipment on


                                       1
<PAGE>   2


such tower), and construction company for wireless telecommunications tower
sites for Carrier and its Affiliates in the BTAs listed on SCHEDULE A attached
hereto and those BTAs agreed upon by the parties made subject to this Agreement
by amendment (the "APPLICABLE GEOGRAPHIC AREA"). For purposes of this Agreement,
"AFFILIATES" with respect to either party, shall mean companies which control,
are controlled by, or under common control with that party. For purposes of this
Agreement, the word "control" shall mean the ownership, directly or indirectly,
of the power to direct or cause the direction of the management and policies of
an entity, or the power to veto major policy decisions of any such entity,
whether through the ownership of voting securities, by contract or otherwise.
During the term of this Agreement, Carrier shall not engage any third party or
Affiliate directly or indirectly to perform build-to-suit, site acquisition,
construction, or equipment installation services in the Applicable Geographic
Area and will not enter into any discussions with any third party or Affiliate
concerning, or furnish any information relating to such services to any third
party or Affiliate, for the purpose of considering, soliciting or inducing any
offer by such third party.

     1.5 RESTRICTIONS ON SERVICES TO OTHERS. During the term of this Agreement,
BTS Company will not provide build-to-suit or site acquisition services for any
other person or entity in the BTAs that are subject to the exclusivity
restrictions set forth in SECTION 1.4, with the exception of (a) any of such
services being provided prior to the date of this Agreement and disclosed to
Carrier in SCHEDULE A attached hereto, and (b) any of such services commenced
after the date of this Agreement for which BTS Company has obtained the prior
approval of Carrier, such approval not to be unreasonably withheld.

                         II. SITE ACQUISITION SERVICES.

     2.1 SITE ACQUISITION SERVICES.

     (a) Carrier shall establish small geographic areas within the Applicable
Geographic Area within which a cell site or transmission tower shall be located,
based on the network grid's RF design (a "SEARCH RING"). For each Search Ring,
Carrier shall provide (i) minimum tower specifications, (ii) desired mounting
height, (iii) a description of the equipment that Carrier intends to put on the
tower, including any expansion plans, and (iv) any other technical data
reasonably necessary to permit SBA to effectively identify the candidate sites
that meet Carrier's needs. Carrier will provide to BTS Company its system
network grid, with the established Search Rings overlaid thereon. Carrier will
from time to time, assign Search Rings to BTS Company. BTS Company shall provide
the personnel and facilities which are necessary to locate and lease or license
existing towers, buildings or other structures by Carrier to be used for the
installation of Carrier's equipment ("COLLOCATION SITES") or locate and lease,
license or purchase unimproved real property suitable for the construction and
installation of a communications tower and related facilities by BTS Company
("BTS SITE") and the installation of Carrier's equipment. As used herein,
"SITES" shall refer to both Collocation Sites and BTS Sites. BTS Company shall
perform site acquisition services with respect to each Search Ring in accordance
with the scope of work attached hereto as SCHEDULE B ("SITE ACQUISITION
SERVICES"). BTS Company shall be entitled to compensation from Carrier for the
Site Acquisition Services performed on Collocation Sites as set forth on
SCHEDULE D attached hereto. BTS Company shall be entitled to compensation from
Carrier for the Site Acquisition Services performed on BTS Sites under SECTIONS
2.2, 2.3, 2.4(c), 2.4(f) AND 2.7(c) as set forth on SCHEDULE D attached hereto.
BTS Company hereby acknowledges that Carrier maintains a preference to fulfill
its needs for wireless communications installations via suitable Collocation
Sites that may be available within the respective Search Rings designated
hereunder. In the performance of the Site Acquisition Services, BTS Company
shall use diligent and good faith efforts to maximize collocation opportunities
as a primary responsibility, with BTS Sites to be a secondary fulfillment of
Carrier's needs.


                                       2
<PAGE>   3


     (b) Upon receipt of a Search Ring designated hereunder by Carrier, BTS
Company shall promptly, diligently and professionally perform the Site
Acquisition Services with respect to such Search Ring in accordance with this
Agreement, including, without limitation, the objectives and procedures set
forth in SCHEDULE B attached hereto ("OBJECTIVES AND PROCEDURES").

     (c) Except as expressly authorized in this Agreement or otherwise expressly
authorized by Carrier in writing, BTS Company shall provide all labor,
equipment, material and supplies necessary or appropriate to perform Site
Acquisition Services.

     (d) During the performance of Site Acquisition Services with respect to any
designated Search Ring, BTS Company shall at all times apprise Carrier of any
expressed opposition, protest, litigation or other efforts, whether by an
individual, group, neighborhood association or other organization, to restrict,
alter or prohibit the construction, installation or operation of any structure,
structures or other facilities that Carrier or BTS Company proposes to construct
or operate on any Site within such Search Ring.

     2.2 WITHDRAWAL OF SITE. In the event Carrier elects to withdraw a
Collocation Site at any time or a BTS Site pursuant to the terms of this
Agreement, Carrier shall give BTS Company notice of such withdrawal. In the
event that the withdrawn Site is a Collocation Site, Carrier shall pay BTS
Company 50% of the milestone installment that would be due if the work currently
in progress was completed, 100% of the reimbursable costs which were incurred
prior to the date on which BTS Company receives notice of the withdrawn Site,
and 100% of all other amounts due hereunder for work completed on the Site as of
the date BTS Company receives Carrier's withdrawal notice and shall substitute
the withdrawn Site with an alternative Site or Search Ring within sixty (60)
days ("ALTERNATIVE SITE"), if available. In the event that a withdrawn Site is a
BTS Site, Carrier shall pay BTS Company for the Services (as hereinafter
defined), except where BTS Company otherwise so chooses to develop such BTS Site
for its own purposes, including, without limitation, Site Acquisition Services,
in connection with such Site in the same percentage as though such site was a
Collocation Site using the milestones and amounts set forth in SECTION B(1)(b)
of SCHEDULE D attached hereto. Notwithstanding anything to the contrary
contained in this Agreement, in the event that Carrier rejects or withdraws a
Site due to the Carrier's reasonable conclusion based upon the Carrier's due
diligence pursuant to Section 2.7(b)(v), that there is a material defect
existing with respect to the Site that will materially adversely affect
Carrier's use of the Site as contemplated under this Agreement, then Carrier
shall only be obligated to reimburse BTS Company for third party services in
connection with the withdrawn or rejected Site.

     2.3 SEARCH RINGS DESIGN. Carrier shall have the right at any time in its
sole and absolute discretion to expand or reconfigure a previously designated
Search Ring. In the event that Carrier redesigns a Search Ring for a Collocation
Site beyond 0.5 miles of an urban or suburban Site or 1.5 miles of a rural Site
for which BTS Company has begun but not yet completed all Site Acquisition
Services, then Carrier shall pay BTS Company 100% for all Site Acquisition
Services completed at the time that the notice of redesign is received by BTS
Company, 100% of the reimbursable costs which were incurred prior to the date on
which BTS Company receives notice of such reconfigured Search Ring, and 50% of
the milestone installment that would be due if the work currently in progress
was completed. In the event that such Search Ring was a BTS Site, Carrier shall
pay BTS Company for such Site Acquisition Services in connection with the
original Search Ring in the same percentage as though such site was a
Collocation Site using the milestones and amounts set forth in SECTION B(1)(b)
of SCHEDULE D attached hereto. For all Site Acquisition Services rendered for
the redesigned search ring, in the event that the Site in the redesigned Search
Ring is a Collocation Site, Carrier shall pay BTS Company 100% for all
milestones performed and 100% of the reimbursable costs which are incurred.
Carrier agrees not to develop any site within any withdrawn Search


                                       3

Rings or an original Search Ring which has been subsequently redesigned as a
tower site and each party hereto further agrees not to transfer the associated
Work Product to any third party, including Affiliates

     2.4 TERM OF SITE ACQUISITION SERVICES AGREEMENT; DEFAULT.

     (a) The term of this Agreement (the "Site Acquisition Term") commenced as
of February 22, 2000 and shall expire on December 31, 2001.

     (b) A party shall be in default under this Agreement with respect to a Site
or a Search Ring if such party breaches an obligation or covenant under this
Agreement to be performed with respect to that Search Ring or Site, which breach
is not cured within thirty (30) days after the breaching party's receipt of
written notice; provided, however, that so long as the defaulting party
commenced appropriate curative action within such thirty (30) day period, and
thereafter diligently prosecutes such cure to completion as promptly as
possible, the cure period will be extended until the cure is completed.

     (c) If BTS Company is in default under this Agreement with respect to a
Site or Search Ring, Carrier shall have the right to terminate this Agreement as
to the applicable Site or Search Ring only. In the event of such a termination,
Carrier shall have the right to terminate BTS Company's right to complete the
Services with respect to the Site or Search Ring subject to the default, and
Carrier shall have the right to complete or engage a third party to complete
such Services.

     (d) If Carrier is in default under this Agreement with respect to a Site or
Search Ring, BTS Company shall have the right to terminate this Agreement as to
the applicable Site or Search Ring only.

     (e) Neither a termination as to any particular Search Ring or Site, nor the
expiration of this Agreement shall affect:

               (i) the terms of the MSA or any SLA as such agreements affect any
          Site or Search Ring not subject to a default, which has been entered
          into by the parties prior to the date of termination of this Agreement
          as to any particular Search Ring or Site, which shall continue in
          accordance with its terms and conditions;

               (ii) the terms of this Agreement that apply to any SLA which has
          been entered into by the parties prior to the date of termination of
          this Agreement and is not subject to a default;

               (iii) any duties or obligations for payment or performance that
          are or become owing hereunder prior to the effective date of such
          termination;

               (iv) the terms of this Agreement that apply to any Search Ring
          which was issued prior to the date of termination of this Agreement
          that is not the subject of a default; or

               (v) any other duties or obligations that expressly survive the
          termination or expiration hereof.

     (f) A default regarding one Search Ring or Site shall not constitute a
default under this Agreement or with respect to any other Search Ring or Site.
Notwithstanding the previous sentence, in the event that BTS Company is in

obligations with respect to the Sites and Search Rings subject to the default
shall be governed by SECTION 2.4(c). With respect to Search Rings issued in the
BTA subject to the default after BTS Company's exclusivity rights have
terminated, Carrier shall have the right to perform the Services or to engage a
third party to perform the Services with the exception of the construction
services described in the next sentence. Notwithstanding the termination of BTS
Company's rights of exclusivity under SECTION 1.4 with respect to a BTA subject
to a default described in the second sentence of this section and provided that
BTS Company is not in default with respect to the Construction Management
Services or construction scope of work or deliverable work product, BTS Company
shall have the right to construct the Tower Facilities (as hereinafter defined)
and perform the Construction Management Services with respect to BTS Sites, and
may perform Carrier Installation Services with respect to such BTS Sites upon
Carrier's request on a Site resulting from Search Rings issued in the BTA
subject to the default after BTS Company's rights of exclusivity under SECTION
1.4 are terminated. BTS Company shall be paid for those Services pursuant to the
terms of this Agreement. With respect to all Search Rings issued in a BTA
subject to a default described in the second sentence of this section after the
termination of BTS Company's rights of exclusivity under SECTION 1.4, Provided

BTS Site are performed to the satisfaction of BTS Company, Carrier shall convey
the Tower Facilities and any site development material not subject to
confidentiality requirements, including, without limitation, ground leases,
title reports, environmental reports and geotechnical reports to BTS Company
upon completion of the Services with respect to such Search Ring lien free
pursuant to assignment documentation reasonably acceptable to both parties, and
BTS Company shall reimburse Carrier for the reasonable costs of completing the
Services, provided that Carrier provides BTS Company with reasonable
substantiation for such costs. BTS Company and Carrier shall execute an SLA for
the applicable Site simultaneously with the conveyance of the site development
material and such Site shall be subject to the terms of the MSA as though BTS
Company had completed all of the Services for such Site.

     2.5 GROUND LEASES. The acquisition of BTS Sites by BTS Company pursuant to
this Agreement shall be accomplished by BTS Company purchasing the BTS Site or
leasing the BTS Site using a lease agreement between BTS Company and the lessor
(hereafter the "GROUND LEASE") as approved by Carrier or Carrier's authorized
representatives in accordance with SECTION 2.7(b)(v). The acquisition of
Collocation Sites by BTS Company pursuant to this Agreement shall be
accomplished using a lease agreement between Carrier and the lessor, which
Carrier shall provide to BTS Company or on such other form which Carrier may, in
its sole discretion, approve.

     2.6. ACCEPTANCE AND REJECTION OF COLLOCATION SITES. Carrier may at any time
in its sole and absolute discretion accept or reject any proposed Collocation
Site. Without limiting the foregoing, Carrier may withdraw its prior acceptance
of a Collocation Site and thereby reject such Collocation Site. A withdrawal or
any rejection by Carrier of a Collocation Site shall not affect its obligation
for fees earned through the date of termination for Site Acquisition Services as
more particularly described in SECTION 2.2.

     2.7 ACCEPTANCE AND REJECTION OF BTS SITES; EXECUTION AND DELIVERY OF SLAS

     (a) A BTS Site shall be deemed to be an accepted BTS Site from and after
the date that the Candidate Site which corresponds to the BTS Site has been
approved by Carrier pursuant to SECTION 2(a) of SCHEDULE B attached hereto and

<PAGE>   6


     (b) Carrier may at any time prior to the parties' execution and delivery of
an SLA corresponding thereto, and in Carrier's sole and absolute discretion,
reject any BTS Site. In the case of a BTS Site that is accepted by Carrier, the
following shall apply:

               (i) BTS Company shall continue the diligent, thorough and
          professional prosecution of Site Acquisition Services (including the
          completion of Ground Lease negotiations and required zoning, land use
          and permitting matters) necessary for the construction of a
          communications tower and related facilities consistent with the
          criteria theretofore identified by Carrier;

               (ii) Subject to SECTION 2.7(b)(iii) below, BTS Company and
          Carrier shall prepare and finalize the SLA (and exhibits thereto)
          applicable to such BTS Site;

               (iii) Within ten (10) days following Carrier's notice from BTS
          Company that BTS Company has received all necessary zoning or other
          land use permits or approvals applicable to the improvements to be
          constructed by BTS Company on the BTS Site and the completion of Site
          Acquisition Services in accordance with the Objectives and Procedures,
          but subject to SECTION 2.7(b)(iv) below, BTS Company shall prepare an
          SLA for such BTS Site, Carrier shall provide to BTS Company all
          information reasonably requested by BTS Company to enable BTS Company
          to prepare the SLA and Carrier and BTS Company shall execute and
          deliver the SLA applicable thereto. Upon the full execution of an SLA,
          BTS Company shall thereafter perform its obligations thereunder in
          accordance with the SLA and this Agreement. Notwithstanding any
          provision of this Agreement to the contrary, in the event that Carrier
          neither accepts nor rejects the BTS Site within ten (10) days as
          provided herein, but subject to SECTIONS 2.7(b)(iv) AND 2.7(b)(v)
          below, BTS Company may, at BTS Company's sole option either (A) deem
          the BTS Site approved (in which event BTS Company shall be entitled to
          compel Carrier to execute a SLA with respect to the BTS Site or
          execute the SLA on behalf of Carrier) or (B) deem the BTS Site to be
          rejected and make demand on Carrier for payment of the fees earned for
          Site Acquisition Services.

               (iv) Carrier may in its sole and absolute discretion withdraw its
          prior acceptance of a BTS Site, and thereby reject said BTS Site, at
          any time prior to the BTS Company parties' execution and delivery of
          the SLA for such BTS Site, subject to Carrier's right to terminate an
          SLA pursuant to the MSA.

               (v) Notwithstanding anything to the contrary contained in this
          Agreement, in the event that Carrier's due diligence investigation or
          review of BTS Company's due diligence investigation with respect to a
          Site causes Carrier to reasonably believe that Carrier's use and
          occupancy of the Site would be adversely affected as a result of such
          review, Carrier shall have the right through its legal counsel to
          reject such Site by providing BTS Company with notice prior to BTS
          Company's commencement of construction at the Site, but no later than
          within thirty (30) days of Carrier's receipt of notice from BTS
          Company that BTS Company has provided Carrier with all documentation
          required pursuant to this Agreement. It further being agreed and
          acknowledged that no SLA shall be executed or construction commenced
          until such time as BTS Company has received Carrier's approval as
          required under this paragraph, provided, however, that Carrier and
          Carrier's counsel's failure to respond within such thirty (30) day
          period shall be deemed an approval.

     (c) In the event of a rejection by Carrier of a BTS Site, including a
rejection after a prior acceptance thereof (except as specified in the last
sentence of Section 2.2) as described above in SECTION 2.7(b) hereof, Carrier
shall be obligated for the payment to BTS Company for Site Acquisition Services


                                       6

incurred prior to such rejection with respect to the Search Ring containing such
BTS Site in accordance with SECTION 2.2. In the event of such a rejection,
Carrier agrees not to develop the rejected BTS Site as a tower site and further
agrees not to transfer the associated Work Product to any third party, including
Affiliates.

     (d) In the event of a rejection by Carrier of a BTS Site, BTS Company may
elect to forego the compensation set forth in SECTION 2.2 and retain the Work
Product.

     (e) In the event that BTS Company's due diligence investigation of a BTS
Site reveals any defect in such site which BTS Company reasonably believes would
materially adversely affect BTS Company's use or ownership of such BTS Site, or
would limit BTS Company's ability to lease space on the applicable Tower to one
broad band tenant, BTS Company shall be entitled to reject such Site upon notice
to Carrier. In such event, Carrier shall have the right to designate another
candidate site as the preferred candidate. BTS Company shall bear all costs
associated with Site Acquisition Activities and all costs associated with the
due diligence investigation, zoning, and permitting of such Site.

     2.8 CONTINUED PERFORMANCE OF SITE ACQUISITION SERVICES FOLLOWING SITE
ACCEPTANCE OR REJECTION. Unless otherwise notified by Carrier, BTS Company

by and construed in accordance with the laws of the state where the applicable

in accordance with the laws of the State of Texas, excluding the conflict of law
provisions thereof. Each of the parties acknowledge that a substantial portion
of negotiations and execution of this Agreement occurred or shall occur in

or court rules in said State.

     6.7 WAIVER. The failure of either party to insist upon strict performance
of any obligation hereunder, irrespective of the length of time for which such
failure continue, shall not be a waiver of such party's right to demand strict
compliance in the future. No consent or waiver, express or implied, to or of any
breach or default in the performance of any obligation hereunder shall
constitute a consent or waiver to or of any other breach or default in the
performance of the same or any other obligation hereunder.
