                               PROSPECTUS SUMMARY

     This summary highlights information that we believe is especially important
concerning our business and this offering of common stock. It does not contain
all of the information that may be important to your investment decision. You
should read the entire prospectus, including "Risk Factors" and our financial
statements and related notes, before deciding to invest in our common stock.

                                    ALAMOSA

GENERAL


     Alamosa is a provider of wireless personal communications 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 personal
communications services under the Sprint and Sprint PCS brand names in a
territory comprising approximately 8.4 million residents. These residents are
primarily located in smaller cities and in markets with above average growth
rates in Texas, New Mexico, Arizona, Colorado and Wisconsin. We are a
development stage company with very limited operations, very limited revenues,
significant losses, substantial future capital requirements and an expectation
of continued significant 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. We expect to cover a total of approximately 4.1
million residents by the end of 2000 and 5.5 million residents by the end of
2001, at which point we expect to have completed our build-out obligations to
Sprint PCS and expect to have covered approximately 65% of the resident
population in our territory. 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, approximately 31,850 Sprint PCS
subscribers were based in our territory.


     We were formed in July 1998, as a Texas limited liability company.
Immediately before the closing of this offering, we will reorganize into a
Delaware holding company structure. See "The Reorganization." Our principal
executive office is located at 4403 Brownfield Highway, Lubbock, Texas 79407.
Our telephone number is (806) 722-1100.

STRATEGIC RELATIONSHIP WITH SPRINT PCS

     We believe that our strategic relationship with Sprint PCS provides
significant competitive advantages. Sprint PCS is a national provider of
wireless services and products. Sprint PCS's subscriber base has more than
tripled in size since the end of June 1998, making Sprint PCS one of the fastest
growing wireless service providers in the United States.


     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. Sprint PCS handles our billing and collections and pays us 92%
of "collected revenues" from subscribers based in our territory and retains the
remaining 8%, as more fully described in "Our Affiliation Agreements with Sprint
PCS -- The Management Agreement -- Service Pricing, Roaming and Fees." We also
receive other revenues, including Sprint PCS roaming revenues for each minute
that Sprint PCS customers based outside our territory use our portion of the
Sprint PCS network and 100% of revenues from handset sales.


                                        1
<PAGE>   6

     We believe that our affiliation with Sprint PCS allows us to establish high
quality, branded wireless services more quickly, at a lower cost and with lower
initial capital requirements than would otherwise be possible. For example, we
benefit from Sprint PCS's:

     - Marketing. We market products and services through Sprint PCS's existing
       relationships with major national retailers under the highly recognizable
       Sprint and Sprint PCS brand names.


     - National Network. Customers in our territory can immediately access
       Sprint PCS's growing network in 280 major metropolitan areas across the
       country.



     - Advanced Technology. We believe that the technology used by Sprint PCS
       provides advantages in capacity and voice-quality, as well as access to
       advanced features such as wireless Internet access.


     - Handset and Equipment Availability and Pricing. Sprint PCS's purchasing
       leverage allows us to acquire handsets and network equipment more quickly
       and at a lower cost than we could without our affiliation with Sprint
       PCS.

ATTRACTIVE TERRITORY

     We believe that our territory is attractive for several reasons, including:

     - High Growth Markets. The overall population growth rate in our territory
       has been approximately 42% above the national average.

     - Fewer Competitors. We expect to face fewer competitors in our markets
       than is generally the case for wireless service providers operating in
       more urban areas.

     - Opportunity for Sprint PCS Roaming Revenue. We anticipate that we will
       have significant roaming revenue from Sprint PCS subscribers based
       outside our territory who use our portion of the Sprint PCS network.

ADEQUATE FUNDING TO COMPLETE OUR NETWORK


     Starting in June 1999, we have launched Sprint PCS service in eleven
markets. We anticipate that the proceeds of this offering, when combined with
the committed level of debt financing from Nortel Networks, Inc., will be
adequate to fund future required capital expenditures, working capital
requirements, operating losses and other cash needs of our business. Further, we
believe that this level of financing is adequate to achieve the objective in our
business plan of covering approximately 65% of the resident population in our
territory by the end of 2001 and to exceed the build-out requirements contained
in our affiliation agreements with Sprint PCS. However, we may need additional
capital or debt financing due to greater than expected operating losses, the
addition of new markets to our territory or unanticipated increases in the
capital required to build-out our portion of the Sprint PCS network.

                                  RISK FACTORS

     You should carefully consider the following risk factors in addition to the
other information contained in this prospectus before purchasing our common
stock.

RISKS RELATED TO OUR RELATIONSHIP WITH SPRINT PCS

     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 "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:

     - 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.


     - 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.


                                        6
<PAGE>   11


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


     - 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.


     - Sprint PCS could breach its payment or other obligations under our
       affiliation agreements, which could result in a substantial reduction in
       our revenues, difficulty in obtaining important financial or subscriber
       information or a severe restriction on our ability to conduct business.



     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:


     - delays or problems in our own operations or service;

     - 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;

     - a loss of Sprint PCS customers; and


     - 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.


                                        7
<PAGE>   12

     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.


     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:



     - $3.8 million paid during 1999;



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



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



     - 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 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 "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 "Management -- Directors and Executive
Officers" and "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
$18.2 million in operating losses through September 30, 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


                                        9
<PAGE>   14


capital losses through the year 2001 were approximately $283 million. We plan to
finance these requirements using the funds received from this offering and the
remaining $178.1 million available under the Nortel financing as of December 31,
1999. 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:

     - design and engineer our systems;

     - construct base stations, switch facilities and towers;

     - lease base stations;

     - install T-1 lines; and

     - deploy our wireless personal communications services network systems.


     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 Speciality Capital Services, Inc., now a subsidiary of
American Tower Corporation. Speciality in turn has separate leasing arrangements
with each of the owners of the sites. If Speciality or American Tower
Corporation were to become insolvent or Speciality 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:



     - 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;



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



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



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


                                       10
<PAGE>   15


     - 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 "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 "Business -- Roaming." For further information on the Sprint PCS
network technology, see "Business -- Technology."



     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:

     - continued development of our operational and administrative systems;

     - stringent control of costs of network build-out;

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

     - increased marketing activities;

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

     - 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.


                                       11
<PAGE>   16


     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
"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.


     RISKS RELATING TO THE YEAR 2000 ISSUE MAY CAUSE INTERRUPTIONS IN SERVICE


     Our systems, the systems of Sprint or Sprint PCS and the systems of other
third parties upon whom we depend may experience system interruptions resulting
from the year 2000 date change. If difficulties do arise, our business may not
be operational for a period of time. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Impact of Year 2000 Issue on
the Operations and Financial Condition of Alamosa."

<PAGE>   17


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 $72.9
million. In addition, under our current business plan, we expect to incur
substantial additional debt, including an anticipated $156.0 million if we
complete 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:



     - 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;



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



     - 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:



     - acquiring minimum numbers of Sprint PCS subscribers;



     - providing coverage to a minimum number of residents; and



     - 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:



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



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



     - 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.


                                       13
<PAGE>   18


     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 we plan to sell will
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:



     - consummating designated types of mergers or consolidations;



     - paying dividends or other distributions to our stockholders;



     - making investments;



     - selling assets;



     - repurchasing our common stock;



     - changing lines of business;



     - borrowing additional money; and



     - 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.


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:



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



     - 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.

     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.


                                       14
<PAGE>   19


     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:


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



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



     - 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:

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

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

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

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

     - 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 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 "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.

RISKS RELATING TO THE OFFERING

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


     Upon completion of this offering of common stock, our existing
stockholders, directors and officers will beneficially own approximately 84% of
our outstanding common stock on a diluted basis. Consequently, those persons, if
they act as a group, will be 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 "Management" and
"Principal Stockholders."



     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.
Six months after the completion of this initial public offering, approximately
45,818,000 shares of common stock, including shares underlying options
immediately exercisable upon completion of this offering, will no longer have
transfer restrictions imposed by a lock-up period. One year after the completion
of this initial public offering, approximately 48,500,000 shares of common stock
will be eligible for sale pursuant to Rule 144 of the Securities Act of 1933.
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.
See "Shares Eligible for Future Sale" for more information.



     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. See "Description of Capital Stock -- Provisions of
the Certificate of Incorporation and Bylaws That May Prevent Takeovers" for more
information.



     THE PRICE OF OUR COMMON STOCK MAY BE VOLATILE, WHICH COULD RESULT IN WIDE
FLUCTUATIONS IN OUR STOCK PRICE



     The market price of initial public offerings of growth stage
technology-industry stocks have recently experienced wide fluctuations. Our
stock price may fluctuate in a manner unrelated to or disproportionate to our
performance.

              THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS

     This prospectus contains statements about future events and expectations,
which are "forward-looking statements." Any statement in this prospectus that is
not a statement of historical fact may be deemed to be a forward-looking
statement. These forward-looking statements include:

     - forecasts of growth in the number of consumers using wireless personal
       communications services and in estimated populations;

     - statements regarding our plans for, schedule for and costs of the
       build-out of our portion of the Sprint PCS network;

     - statements regarding our anticipated revenues, expense levels, liquidity
       and capital resources, operating losses and projections of when we will
       launch commercial wireless personal communications service in particular
       markets;

     - statements regarding expectations or projections about markets in our
       territory;


     - statements regarding the year 2000 date change; and


     - other statements, including statements containing words such as "may,"
       "might," "could," "would," "anticipate," "believe," "plan," "estimate,"
       "project," "expect," "seek," "intend" and other similar words that
       signify forward-looking statements.


     These forward-looking statements involve known and unknown risks,
uncertainties and other factors that may cause our actual results, performance
or achievements to be materially different from any future results, performance
or achievements expressed or implied by these forward-looking statements.
Specific factors that might cause such a difference include, but are not limited
to:


     - our dependence on our affiliation with Sprint PCS;

     - the need to successfully complete the build-out of our portion of the
       Sprint PCS network on our anticipated schedule;

     - our limited operating history and anticipation of future losses;

     - our dependence on Sprint PCS's back office services;

     - potential fluctuations in our operating results;

     - our potential need for additional capital or the need for refinancing
       existing indebtedness;

     - our potential inability to expand our services and related products in
       the event of substantial increases in demand for these services and
       related products;

     - changes or advances in technology;

     - our competition; and

     - our ability to attract and retain skilled personnel.

     For a discussion of some of these factors, see "Risk Factors" beginning on
page 6.

                                USE OF PROCEEDS


     We estimate that the net proceeds we will receive from the sale of the
common stock we are offering, after deducting underwriting discounts and
commissions and estimated offering expenses, will be approximately $139 million,
or an aggregate of approximately $160 million if the underwriters exercise their
over-allotment option in full, based on an assumed initial public offering price
of $14.00 per share, the midpoint of the range set forth on the cover page of
this prospectus. We intend to use the net proceeds from the common stock
offering, together with remaining cash proceeds available under the Nortel loan
financing at January 1, 2000 of $152.5 million, to fund the following cash
expenditures through 2002:



     - 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;



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



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


     - general corporate purposes.


     We will retain broad discretion in the allocation of the net proceeds of
this offering. This discussion represents our best estimate of the allocation of
the net proceeds of this offering based upon our current plans. Actual
expenditures may vary substantially from these estimates 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 the sale of
the common stock in short-term investment grade securities, which will earn
interest.



     We anticipate that the proceeds from our proposed 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. However, we cannot assure you that our notes offering
will be completed.


                                DIVIDEND POLICY


     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 Alamosa PCS Holdings, Inc.'s 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.

     The following table shows our cash and cash equivalents, short term debt
and capitalization:

     - as of September 30, 1999;

     - as adjusted to reflect the sale in the offering of 10,714,000 shares of
       common stock at an initial offering price of $14.00 per share, the
       midpoint of the range on the cover of the prospectus, less underwriting
       discounts and commissions and estimated offering expenses of $11.1
       million; and


     - as further adjusted to reflect (1) the sale in the offering of 10,714,000
       shares of common stock at an initial offering price of $14.00 per share,
       the midpoint of the range on the cover of the prospectus, less
       underwriting discounts and commissions and estimated offering expenses of
       $11.1 million, (2) the issuance of an aggregate principal amount at
       maturity of $     million in senior discount notes with estimated gross
       proceeds of $156.0 million, less underwriting discounts and commissions
       and estimated offering expenses of $5.0 million and (3) the prepayment of
       an aggregate of $75.0 million of indebtedness under the Nortel facility,
       consisting of the prepayment of $59.7 million outstanding on September
       30, 1999 and cash equal to $15.3 million designated to prepay borrowings
       under the Nortel facility incurred after September 30, 1999.

                                    DILUTION


     Our net tangible book value at September 30, 1999, was $13.2 million or
$0.27 per share of common stock. Net tangible book value per share represents
the amount of our total tangible assets reduced by the amount of total
liabilities and divided by the number of shares of common stock outstanding.
Assuming an initial public offering price of $14.00 per share, after giving
effect to our sale of 10,714,000 shares of common stock in the offering, and
deducting underwriting discounts and commissions and estimated offering
expenses, our as-adjusted net tangible book value as of September 30, 1999 would
have been approximately $152 million, or $2.57 per share. This represents an
immediate dilution of $11.43 per share to new investors purchasing shares of
common stock in the offering and an immediate increase in net tangible book
value to existing stockholders of $2.30 per share.


     Dilution per share represents the difference between the price per share to
be paid by new investors and the net tangible book value per share immediately
after the sale of common stock in this offering. The following table illustrates
the per share dilution:

     The following table summarizes, on an as-adjusted basis as of September 30,
1999, the number of shares of common stock purchased, the total consideration
paid and the average price per share paid by our existing stockholders and by
new investors purchasing shares of common stock in the offering, assuming an
offering price of $14.00 per share, the midpoint of the range on the cover page
of this prospectus, before the deduction of underwriting discounts and
commissions and estimated offering expenses of $11.1 million payable by us:

     The foregoing tables assume no exercise of the underwriters' over-allotment
option and no exercise of outstanding stock options and warrants. To the extent
that any shares are issued at exercise prices below the net tangible book value
per share in connection with outstanding options, you will experience further
dilution. See "Management -- Benefit Plans -- 1999 Long Term Incentive Plan,"
"Management -- Employment Agreements" and "Description of Our
Indebtedness -- The Nortel Credit Facility -- Warrants."


     As part of this sale of our common stock, the underwriters agreed to
reserve a maximum of 10% of the shares of our common stock to be sold in this
offering for sale to our current stockholders at a price per share equal to the
public offering price less the underwriting discount. The underwriters will not
be entitled to any discount or commission on these shares and the proceeds to us
will be the same as if the shares were sold to the general public. However, the
number of shares of common stock available for sale to the general public will
be reduced to the extent of sales of shares to our current stockholders.

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

     You should read the following discussion and analysis when you read the
consolidated financial statements and the related notes included in this
prospectus. 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 "Risk Factors" and "This Prospectus
Contains Forward-Looking Statements."

OVERVIEW


     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 September 30, 1999, we had not generated significant revenues
from customers, and our accumulated deficit was $18.6 million. Through September
30, 1999 we incurred $66.8 million, and through December 31, 1999 we incurred
$75.1 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, approximately 31,850 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 "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:



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



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



     - competitive pricing pressures; and



     - 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 selling, general and administrative expenses.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses for the period in the amount of $949,445 were comprised
primarily of legal and other professional services of $704,341 related to the
start up of our business and the development of our systems. In addition, we
incurred $167,246 of human resource costs related to preparation for the 1999
launch of our network. Virtually all selling, 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."

     NINE MONTH PERIOD ENDED SEPTEMBER 30, 1999

     Net Loss. Our net loss for the nine months ended September 30, 1999 was
$17,688,419 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 six other market launches during the period.


     Service Revenues. Service revenues during the period in the amount of
$1,187,008 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.


                                       24
<PAGE>   29


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 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
$110.29 for the period from June 26, 1999 to September 30, 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 $813,052. 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 Services. Expenses totaling $818,678 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 Products Sold. The cost of products sold totaling $794,963 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 nine months ended September 30, 1999, the handset
subsidy totaled $1,194,000 and there was no expense related to handset subsidy
in the period prior to the nine months ended September 30, 1999.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses totaling $9,194,937 during the period include sales and
marketing expenses of $2,282,000, the 8% of collected revenue retained by Sprint
PCS of $54,000 and amounts retained by Sprint PCS for customer service of
$212,000, as well as billing, network monitoring, human resources and other
services. 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. We have incurred significant selling, 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."

     Equity Participation Compensation Expense. Equity participation
compensation expense totaled $6,822,037 for the period. This expense was
determined using the provisions of Accounting Principles Board Opinion No. 25
"Accounting for Stock Issued to Employees" for variable options and was based on
the estimated intrinsic value of the options at September 30, 1999. The
estimated intrinsic value represents the excess of the estimated fair value
equal to the initial public offering price over the exercise price of the
option.

                                       25
<PAGE>   30

     General and Administrative Expenses -- Related Parties. General and
administrative expenses -- related parties totaled $680,006 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 $936,736. 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 $444,746
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 $885,868 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 -- Loans and Interest Options." Gains
or losses on hedging transactions related to interest rates will be netted
against interest expense.

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 September 30, 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 September 30, 1999, we had a $123.0 million senior credit facility with
Nortel, of which $59.7 million had been drawn. We have since signed a letter of
intent to increase the facility to $250.0 million to be effective as of the
closing of this offering. The terms of the facility do not require cash interest
payments until the earlier of:



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



     - February 2002; and



     - the date the Tranche C Commitment is fully funded.



Principal payments are scheduled to begin on the earlier of:



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



     - December 31, 2002.


                                       26
<PAGE>   31


     Our financing with Nortel will be used to purchase equipment, pay interest
and cover approved working capital costs. In connection with the facility, we
are to issue springing warrants to Nortel that come into existence and become
exercisable on the second anniversary of the closing of the facility unless we
meet specified conditions prior to that date. If we complete our offering of
senior discount notes, the Nortel facility requires that we prepay at least
$75.0 million of indebtedness under the Nortel financing, which prepayment will
prevent the exercise of the warrants by Nortel. We cannot assure you that we
will choose to complete our notes offering and prepay any portion of the Nortel
financing. The warrants would be exercisable to purchase shares of our common
stock representing 2% of the total shares outstanding on a fully-diluted basis
as of the closing of the offering. The exercise price of the warrants would be
equal to the initial public offering price of the common stock sold in this
offering. We will amortize the fair value of these contingent warrants as debt
issuance costs over the term of the Nortel loans. For more information on the
financing facility, see "Description of Our Indebtedness -- The Nortel Credit
Facility."


     Net cash used by operating activities was $127,954 for the inception period
ending December 31, 1998, and $9,338,888 for the nine months ending September
30, 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 $1,342,969 for the inception
period ending December 31, 1998, and $18,784,600 for the nine month period
ending September 30, 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 $15,000,000 consisting of
capital contributions for the inception period ending December 31, 1998 and
$22,048,720 consisting primarily of capital contributions of $10,000,000 and
Nortel draws of $12,289,286 for the nine month period ending September 30, 1999.



     As of September 30, 1999, the primary sources of liquidity for Alamosa were
$7.5 million in cash and $63.3 million of unused capacity under the $123.0
million Nortel credit facility.



     We anticipate that the proceeds from this offering, when combined with the
committed level of debt financing from Nortel, will be adequate to fund required
capital expenditures, working capital requirements, operating losses and other
cash needs of our current business plan. We estimate that we will require
approximately $283 million to complete the current build-out plan and fund
working capital losses through the year 2001. The following table does not
reflect the consummation of our senior discount notes offering and sets forth
our estimates at January 1, 2000 of our sources and uses of funds necessary to
fund our capital expenditures through the completion of our network build-out
plan in 2002:

     (1) We expect to incur losses in earnings before interest, taxes,
         depreciation and amortization in excess of $52 million, but expect to
         offset a portion of these losses in the period presented.



     (2) Debt service payments are composed of:

</TABLE>



     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 these estimates, 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."


     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 September 30,
1999 the capital leases totaled $853,965 and included long-term capital lease
obligations of $832,684. See "Description of Our Indebtedness -- The Nortel
Credit Facility -- Loans and Interest Options." Amortization in the amount of
$20,661 was recorded under these leases through September 30, 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 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:

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

     - the review of core critical systems and applications;

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

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

                                       28
<PAGE>   33


     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.


QUANTITATIVE AND QUALITATIVE DISCLOSURE 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.

     We are subject to some interest rate risk on our financing from Nortel and
any future floating rate financing.

     The following table presents the estimated future outstanding long-term
debt at the end of each year and future required annual principal payments for
each year then ended associated with the senior discount notes, capital leases
and the Nortel financing based on our projected level of long-term indebtedness:

(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 5.5% for all periods
    presented.

     Our primary market risk exposure relates to:

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

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

     - 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. 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.


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.

                                    BUSINESS

     References in this prospectus 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 prospectus 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. Unless otherwise
indicated, growth rate statistics are based on U.S. Census Bureau data for
growth during the period from 1990 to 1998.

OVERVIEW

     Alamosa is a provider of wireless personal communication services in the
southwestern and midwestern United States. We are part of the Sprint PCS
network. 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 our territory. We have
recently amended our affiliation agreements with Sprint PCS to expand our
territory so that it will include approximately 8.4 million residents. These
residents are primarily located in smaller cities and in markets with above
average growth rates in Texas, New Mexico, Arizona, Colorado and Wisconsin.

     We believe that our strategic relationship with Sprint PCS provides
significant competitive advantages by allowing us to establish high quality,
branded wireless services more quickly, at a lower cost and with lower initial
capital requirements than would be possible without our affiliation with Sprint
PCS.

     Our territory offers several competitive advantages. Our territory is a
high growth area. The overall population growth rate in our territory for the
period from 1990 to 1998 was approximately 1.5% per year, approximately 42%
above the national average. We expect to face fewer competitors in our territory
than is generally the case for wireless service providers operating in more
urban markets. We expect to have significant Sprint PCS roaming revenue because
our territory adjoins several major Sprint PCS markets and contains several
vacation destinations and border markets.


     Since our inception in July 1998, we have launched Sprint PCS service in
eleven markets in which our systems cover approximately 2.7 million residents
out of approximately 3.9 million total residents. 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,
approximately 31,850 Sprint PCS subscribers were based in our territory. We
anticipate that the proceeds of this offering, when combined with previously
funded equity and the committed level of debt financing from Nortel, will be
adequate to fund required capital expenditures, working capital requirements,
operating losses and other cash needs of our business.


WIRELESS INDUSTRY GROWTH

     Wireless communications systems use a variety of radio frequencies to
transmit voice and data. Broadly defined, the wireless communications industry
includes one-way radio applications, such as paging or beeper services, and
two-way radio applications, such as wireless personal communications services,
cellular telephone services and enhanced specialized mobile radio service.

     Since the introduction of commercial cellular service in 1983, the wireless
communications industry has experienced dramatic growth. The number of wireless
subscribers for cellular, wireless personal communications services and enhanced
specialized mobile radio service has increased from an estimated

340,213 in June of 1985 to an estimated 76.3 million as of June, 1999, according
to the Cellular Telecommunications Industry Association, an international
association for the wireless industry. The following chart sets forth statistics
for the domestic wireless telephone industry as a whole, as published by the
Cellular Telecommunications Industry Association.

     Paul Kagan Associates, Inc., an independent media and telecommunications
research firm, estimates in its publication, Kagan's Wireless Telecom Financial
Databook - 1998, that the number of wireless users will increase to
approximately 131 million by the end of 2002 and 160 million by the end of 2005.
This growth is expected to be driven largely by a substantial projected increase
in wireless personal communications services users, who are forecast to account
for approximately 29% of total wireless users in 2002 and 36% in 2005,
representing a significant increase from approximately 8% as of the end of 1998.
Paul Kagan Associates, Inc. projects that total wireless industry penetration,
defined as the number of wireless subscribers nationwide divided by total United
States population, will grow from an estimated 26% in 1998 to 54% in 2005.

     We believe that a significant portion of the predicted growth in the
consumer market for wireless telecommunications will result from:

     - anticipated declines in costs of service;

     - increased versatility; and

     - increased awareness of the productivity, convenience and privacy benefits
       associated with the services offered by wireless personal communications
       services providers.

We also believe that the rapid growth in the use of notebook computers and
personal digital assistants, combined with emerging software applications for
delivery of electronic mail, fax and database searching, will contribute to the
growing demand for wireless services.

     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.



     Sprint PCS launched commercial wireless personal communications services in
the United States in November 1995. Since then, Sprint PCS has experienced rapid
customer growth and has reported providing service to approximately 4.7 million
customers with average revenue per subscriber of $54 as of September 30, 1999.
In the fourth quarter of 1998, Sprint PCS added approximately 836,000 net
wireless subscribers. Sprint PCS added approximately 2.1 million net wireless
subscribers in the first nine months of 1999. As of September 30, 1999, Sprint
PCS, directly and through affiliates such as us, operated wireless personal
communications services systems in more than 4,000 cities and communities across
the United States. The following table, showing the quarterly end-of-period
subscriber data for Sprint PCS, illustrates Sprint PCS's subscriber growth from
the beginning of 1997 to the end of the second quarter of 1999.

COMPETITIVE STRENGTHS

     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, which we believe is
important to Sprint PCS's national strategy. We believe that our affiliation
with Sprint PCS allows us to establish high quality, branded wireless services
more quickly, at a lower cost and with lower initial capital requirements than
would otherwise be possible. Specifically, we benefit from:

     Immediate Brand Recognition. We market products and services directly under
the Sprint and Sprint PCS brand names. We immediately 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. We expect that customers will choose Sprint
PCS services in large part based on the Sprint and Sprint PCS brand names and
national advertising. Furthermore, because of the Sprint and Sprint PCS brand
names, we are able to reduce the advertising costs that would be required to
establish our own brand in the wireless services market.


     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 believe that our ability to offer access
to Sprint PCS's wireless network, with service in 280 major metropolitan areas
across the country, represents a competitive advantage over regional offerings.
We also 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.


                                       33
<PAGE>   38

     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. Our early stage financing requirements have been
significantly reduced as a result of this investment by Sprint PCS.

     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."

     ATTRACTIVE TERRITORY

     We believe that our territory is attractive for several reasons, including:

     Favorable Demographics. The overall population growth rate in our territory
was approximately 1.5% per year from 1990 to 1998, approximately 42% above the
national average. We serve nine of the 50 fastest growing markets in the United
States, including all of Laredo and a portion of Las Vegas, the two fastest
growing markets. Furthermore, the cities in Mexico directly across from our
border markets have over one million residents and the northbound border
crossings for these markets are approximately 165,000 persons per day. We expect
that some of these people who enter our territory will use the Sprint PCS
network.


     Fewer Competitors. We expect to face fewer competitors in our markets than
is generally the case for wireless service providers operating in more urban
markets. As of September 30, 1999, three or fewer wireless service providers,
other than Alamosa, operated in markets that comprise over 80% of the residents
in our territory. By comparison, less than 10% of the resident population in the
50 most populated markets in the United States are served by four or fewer
wireless service providers. In addition, no single competitor or affiliated
group of competitors has launched service that reaches more than half of the
residents in our territory. We believe that our most extensive competition comes
from Nextel Communications, Inc., which has launched service to less than 40% of
the residents in our territory, followed by VoiceStream Wireless Corporation,
SBC Communications Inc. and United States Cellular Corporation, each of which
has launched service to less than 30% of the residents in our territory. AT&T
Wireless Services, Inc. has launched service to less than 15% of the residents
in our territory. We anticipate that the Sprint PCS brand and the bundled long
distance offers of the "Free and Clear" plans will be effective in this
competitive environment. Sprint PCS's "Free and Clear" calling plans includes
free long distance calling from anywhere on its national network to anywhere in
the United States.


                                       34
<PAGE>   39

     Opportunity for Sprint PCS Roaming Revenue. We receive Sprint PCS roaming
revenue from Sprint PCS when its subscribers based outside our territory roam on
our portion of the Sprint PCS network. For a more detailed description of Sprint
PCS roaming, see "-- Roaming." We anticipate that we will have significant
Sprint PCS roaming revenue for several reasons, including the following:

     - Our territory adjoins several major Sprint PCS markets that are already
       operational, including Dallas/Ft. Worth, Phoenix, Minneapolis, Las Vegas,
       Milwaukee, San Antonio and Colorado Springs.


       These metropolitan statistical areas contain approximately 15.6 million
       residents and the growth rates in these markets was approximately 21.0%
       from 1990 to 1998.


     - We plan to build-out numerous interstate corridors in our territory,
       including:

          - I-17 (Phoenix to Flagstaff);

          - I-25 (El Paso to Albuquerque/Santa Fe and Pueblo to Colorado
     Springs);

          - I-27 (Lubbock to Amarillo);

          - I-35 (San Antonio to Laredo);

          - I-20 (Abilene to Dallas);

          - I-43 (Green Bay to Milwaukee);

          - I-94 (Eau Claire to Minneapolis);

          - I-90 (LaCrosse to Madison); and

          - I-39 (Madison to Wausau).

       While we believe that the build-out of these interstate corridors will
       generate revenue for us, the cost of build-out per resident will be
       higher than other areas due to the lower resident population counts along
       those interstate corridors.

     - Our territory contains popular vacation and tourist destinations,
       including major ski resorts in Colorado and New Mexico such as Taos and
       Telluride.


     - Our territory contains several markets near the Mexico border that we
       believe will benefit from high Sprint PCS roaming revenues generated from
       U.S. business travel to factories along the border and other border
       traffic. From November 1998 to October 1999, Laredo had border crossings
       of approximately:


      - 17 million cars;

      - two million trucks, the highest number of truck crossings along the
        U.S.-Mexico border; and

      - 8 million pedestrians.

       In the same period, El Paso had border crossings of approximately:

      - 14 million cars; and

      - 12 million pedestrians.

     ADEQUATE FUNDING TO COMPLETE OUR NETWORK


     We entered into our affiliation agreements with Sprint PCS in July 1998. 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 these markets. We expect to cover a total of approximately 4.2
million residents by the end of 2000, and 5.5 million residents by the end of
2001, at which point we expect to have completed our build-out obligations to
Sprint PCS and expect to have covered approximately 65% of the resident
population in our territory. 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, approximately 31,850 Sprint PCS
subscribers were based in our territory.



     We anticipate that the proceeds of this offering, when combined with
previously funded equity and the committed level of debt financing from Nortel,
will be adequate to fund required capital expenditures, working capital
requirements, operating losses and other cash needs of our business. Further, we
believe that this level of financing is adequate to achieve the objective in our
business plan of covering approximately 65% of the resident population in our
territory by the end of 2001 and to exceed the build-out requirements contained
in our affiliation agreements with Sprint PCS. We anticipate that the proceeds
from our proposed 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. For more information,
see "Risk Factors -- Risks Particular to Alamosa's Operations -- 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"
and "-- 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."


BUSINESS STRATEGY

     We intend to become a leading provider of wireless personal communications
services in our territory. We believe that the following elements of our
business strategy will enable us to rapidly launch our portion of the Sprint PCS
network, distinguish our wireless service offerings from those of our
competitors and compete successfully in the wireless communications marketplace.

     CAPITALIZE ON OUR AFFILIATION WITH SPRINT PCS


     In all of our markets, we plan to capitalize upon the extensive benefits of
our Sprint PCS affiliation, in particular the Sprint and Sprint PCS brands and
established distribution system. We also plan to emphasize the roaming and
bundled long distance aspects of the "Free and Clear" plans, particularly in
those markets where competitors are not offering one rate plans for service in
areas across the country.


     ACCELERATE MARKET LAUNCH THROUGH EXPERTISE OF THIRD PARTIES

     We have entered into outsourcing or other relationships to benefit from
specialized expertise or economies of scale of third parties and to build-out
our portion of the Sprint PCS network more quickly and with lower initial
capital and staffing requirements. Specifically, those relationships include:

     - The radio frequency design, project management, and networking
       interconnection is being performed by CHR Solutions, Inc., a national
       engineering consulting firm formerly known as Hicks & Ragland Engineering
       Co., Inc. This relationship allows us to quickly plan and begin network
       operations without the initial need to hire additional specialized
       technical personnel.

                                       36
<PAGE>   41

     - We entered into a "build-to-suit" contract with Specialty Capital
       Services, Inc., now a subsidiary of American Tower Corporation. Specialty
       is responsible for:

        - site acquisition;

        - zoning;

        - tower construction; and

        - identifying collocation opportunities.

     This arrangement allows us to focus on the development of a distribution
     network rather than the time consuming task of site acquisition and zoning.

     - We entered into a supply and installation contract with Nortel for
       network infrastructure. Nortel is an international equipment supplier
       well-known for its leadership in code division multiple access technology
       networks. In addition to assuming the responsibility for the integration
       of system operations, Nortel provides us with resources for product and
       service development.

     - We have contracted with Sprint PCS to provide back office services, such
       as:

        - customer activation;

        - handset logistics;

        - billing;

        - customer care; and

        - network monitoring services.


     Because Sprint PCS provides these services, we can be sure that these
services are compatible with, and similar to, the rest of Sprint PCS's
infrastructure and services and that we are in compliance with Sprint PCS's
customer service standards.


     For more information, see "-- Network Operations" and "-- Competitive
Strengths -- Strategic Relationship with Sprint PCS -- Established Back Office
Support Services."

     EXECUTE OPTIMAL BUILD-OUT PLAN

     We have targeted the high population density areas within our territory for
network build-out as well as areas expected to generate significant Sprint PCS
roaming revenue such as major interstates and the border crossings. We are
building an all digital wireless personal communications services network. Our
radio frequency design is optimized to provide in-building coverage with high
capacity traffic. We believe that our cell density, together with the use of
code division multiple access technology, will allow our system to handle more
customers with fewer dropped calls and better clarity than our competitors.

     IMPLEMENT EFFECTIVE OPERATING STRUCTURE

     Our organization and management structure is based on a market-focused
model. Each market area, averaging 1.5 million residents, will be supported by a
small corporate staff that provides services including:

     - network technical support;

     - accounting;

     - human resources;

     - roaming administration;

     - marketing; and

     - Sprint liaison.

     The general manager in each market has responsibility for the profits and
losses for his or her region. We believe that by placing experienced managers in
these markets with the authority to tailor our marketing programs to local
conditions, we can effectively market our products across a wide geographic
area.

     EXPLORE STRATEGIC OPPORTUNITIES TO EXPAND AND FURTHER BUILD-OUT OUR
     TERRITORY IN THE FUTURE

     Upon the successful build-out of our current territory, we plan to explore
strategic expansion of our territory through additional affiliations and further
build-out of our existing territory.

(2) These projected launch dates may change based on a number of factors,
    including shifts in populations or network focus, changes or advances in
    technology, acquisition of other markets and delays in market build-out due
    to reasons identified in "Risk Factors -- Risks Particular to Alamosa's

     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 (1) to the table above.

NETWORK OPERATIONS

     GENERAL


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



     - public switched and long distance interconnection;



     - the implementation of roaming arrangements; and



     - the development of network monitoring systems.


     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,
which will be amended effective as of the closing of the Nortel financing, for
our network equipment and infrastructure, including switches, base stations and
controllers. Pursuant to the agreement, Nortel will also provide installation
and optimization services, such as network engineering and radio frequency
engineering, for the equipment and grant us a nonexclusive license to use all
the software associated with the Nortel equipment. During the term of the
agreement we have committed to purchase a specified amount of equipment and
services from Nortel. Nortel finances these purchases pursuant to the Nortel
credit facility described in "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 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. We are not obligated to pay
this premium once we purchase an additional $32.6 million in equipment and
infrastructure under this 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, 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, Speciality 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
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

                                       41
<PAGE>   46

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.

PRODUCTS AND SERVICES

     We offer established 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:


     100% DIGITAL WIRELESS NETWORK WITH SERVICE ACROSS THE COUNTRY



     We are part of the largest 100% digital wireless personal communications
services network in the country. Sprint PCS customers based in our territory may
access Sprint PCS services throughout the Sprint PCS network, which includes
more than 4,000 cities and communities across the United States.
Dual-band/dual-mode handsets allow roaming on wireless networks where Sprint PCS
has roaming agreements.


     ACCESS TO THE SPRINT PCS WIRELESS WEB

     We support the recently announced Sprint PCS Wireless Web offer in our
portion of the Sprint PCS network. The Sprint PCS Wireless Web allows customers
with data capable handsets to connect their portable computers or personal
digital assistants to the Internet. Sprint PCS customers with data capable
handsets also have the ability to receive periodic information updates such as
stock prices, sports scores and weather reports. Sprint PCS customers with
web-browser enabled handsets have the ability to connect to and browse specially
designed text-based Internet sites on an interactive basis. Sprint PCS has
agreements with Internet providers including Yahoo!, Bloomberg.com, CNN
Interactive, Amazon.com, AmeriTrade.com, MapQuest.com and Weather.com to provide
services for the Sprint PCS Wireless Web. Sprint PCS offers various pricing
options including a fixed number of updates or a bundle of data minutes as
add-ons to existing Sprint PCS "Free and Clear" plans or a bundle of minutes for
a set price that can be used for either data or voice.

     PRICING AND FEATURES

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

     - monthly recurring charges;

     - large local calling areas;

     - bundles of minutes; and

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

                                       42
<PAGE>   47

     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:

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

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

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

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

     - 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:

     - caller ID;

     - call waiting;

     - phone books;

     - speed dial; and

     - 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 cloning 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. Because we serve smaller
markets adjacent to larger metropolitan areas, we believe inbound Sprint PCS
roaming will exceed outbound Sprint PCS roaming. See "Risk Factors -- Risks
Particular to Alamosa's Operations -- 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."


     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. We
benefit from the national advertising at minimal costs to us. 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:

     - the Albuquerque Balloon Fest;

     - the Western Professional Hockey League;

     - minor league baseball teams;

     - local school programs;

     - March of Dimes; and

     - 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


                                       45
<PAGE>   50

customer care at these stores. We plan to add 17 new stores by year-end 2000 and
another five new stores 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 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:

          - Best Buy;

          - Circuit City;

          - Office Depot;

          - Office Max;


          - Staples;



          - Heilig Meyer;



          - Target;



          - K-Mart;



          - Dillards;



          - Montgomery Ward;



          - Foley's;



          - Ritz Camera; and



          - selected May Company department stores.



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


     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.

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 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:

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

     - coordinates calls to and from handsets;

     - allocates calls among the cells within the system; and

     - 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

                                       47
<PAGE>   52

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 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

                                       48
<PAGE>   53

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:

     - Nextel Communications, Inc.;

     - AT&T Wireless Services, Inc.;

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

     - 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:

     - the company that will result from the pending merger between SBC
       Communications Inc. and Ameritech Corporation;


     - VoiceStream Wireless Corporation; and


     - United States Cellular Corporation.

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

     - Airadigm Communications;

     - Poka Lambro PCS, Inc.; and

     - Amarillo CellTelCo.

     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.
                                       49
<PAGE>   54


     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:

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

     - the size of our territory;

     - the location of our markets;

     - our network coverage and reliability;

     - customer care; and

     - pricing.

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:

     - new services and technologies that may be introduced;

     - changes in consumer preferences;

     - demographic trends;

     - economic conditions; and

     - discount pricing strategies by competitors.

LEGAL PROCEEDINGS

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

ENVIRONMENTAL COMPLIANCE

     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.

                   OUR AFFILIATION AGREEMENTS WITH SPRINT PCS

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

     - the management agreement;

     - the services agreement; and

     - 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. We have filed the text of our
affiliation agreements with Sprint PCS and the consent and agreement as exhibits
to the registration statement of which this prospectus is a part.


     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. 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.


THE MANAGEMENT AGREEMENT

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

     - 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;

     - distribute Sprint PCS products and services;

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

     - conduct advertising and promotion activities in our territory; and

     - 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.

                                       53
<PAGE>   58

     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 90 days to determine whether we will
build-out the proposed area.


     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 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
                                       54
<PAGE>   59


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
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:



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



     - 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.

                                       55
<PAGE>   60

     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:

     - termination of Sprint PCS's spectrum licenses;

     - an uncured breach under the management agreement;

     - bankruptcy of a party to the management agreement;

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

     - 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:

     - 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;

                                       56
<PAGE>   61


     - 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


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

See "Business -- Markets and Network Build-Out Plan" 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:

     - 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;


     - 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;


     - 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

     - 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:

     - 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


     - 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.


     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:

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


     - 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 "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:

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

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

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

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

     - 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.

     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.

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.

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

                                       59
<PAGE>   64

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.

CONSENT AND AGREEMENT FOR THE BENEFIT OF THE HOLDER OF 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, the following:

     - Sprint PCS's consent to the pledge of substantially all of our assets,
       including our rights in our affiliation agreements with Sprint PCS;

     - that our affiliation agreements with Sprint PCS 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, unless our
       subsidiaries or assets are sold to a purchaser who does not continue to
       operate the business as a Sprint PCS network, which sale requires the
       approval of the administrative agent, who will initially be Nortel as
       discussed in more detail in "Description of Our Indebtedness -- The
       Nortel Credit Facility -- Syndication;"

     - for Sprint PCS to maintain 10 MHz of wireless personal communications
       services spectrum in all of our markets until the Nortel financing is
       satisfied or our operating assets are sold after our default under the
       Nortel financing;

     - for redirection of payments due to Alamosa under the management agreement
       from Sprint PCS to the administrative agent during the continuation of
       our default under the Nortel financing;

     - for Sprint PCS and the administrative agent to provide to each other
       notices of default by us under the Sprint PCS management agreement and
       Nortel financing, respectively;

     - the ability to appoint interim replacements, including Sprint PCS or a
       designee of the administrative agent, to operate our portion of the
       Sprint PCS network under our affiliation agreements with Sprint PCS after
       an acceleration of our financing from Nortel or an event of termination
       under our affiliation agreements with Sprint PCS;

     - subject to certain requirements and limitations, the ability of the
       administrative agent or Sprint PCS to assign our affiliation agreements
       with Sprint PCS and sell our assets or the partnership interests of our
       operating subsidiaries to a qualified purchaser that is not a major
       competitor of Sprint PCS or Sprint, free of the restrictions on
       assignment and change of control in the management agreement, if the
       Nortel financing has been accelerated after our default; and


     - subject to certain requirements and limitations, that if Sprint PCS
       enters consent and agreement documents with similarly-situated lenders
       that have provisions that are more favorable to the lender, Sprint PCS
       will give the administrative agent written notice of the amendments and
       will amend the consent and agreement with Nortel in the same manner at
       the administrative agent's request; consequently, from time to time,
       Nortel and Sprint PCS may modify the consent and agreement so that it
       will contain terms and conditions more favorable to Nortel.

     SPRINT PCS'S RIGHT TO PURCHASE ON ACCELERATION OF AMOUNTS OUTSTANDING UNDER
     THE NORTEL FINANCING

     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 the
following terms:

     - Sprint PCS elects to make such a purchase within a specified period;

     - the purchase price is the greater of an amount equal to 72% of our Entire
       Business Value or the amount we owe under the Nortel financing;

     - if Sprint PCS has given notice of its intention to exercise the purchase
       right, then the administrative agent is prohibited for a specified period
       after the acceleration or until Sprint PCS rescinds its intention to
       purchase, from enforcing its security interest; and

     - if we receive a written offer that is acceptable to us to purchase our
       operating assets or the partnership interests of our operating
       subsidiaries after the acceleration, then Sprint PCS has the right to
       purchase our operating assets or the partnership interests of our
       operating subsidiaries on terms at least as favorable to us as the offer
       we receive. Sprint PCS must agree to purchase the operating assets or the
       partnership interests of our operating subsidiaries within 14 business
       days of its receipt of the offer, on acceptable conditions, and in an
       amount of time acceptable to us.

     SALE OF OPERATING ASSETS OR THE PARTNERSHIP INTERESTS OF OUR OPERATING
     SUBSIDIARIES TO THIRD PARTIES

     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. Subject to the requirements of applicable law,
including the law relating to foreclosures of security interests, the
administrative agent has two options:

     - to sell the assets or partnership interests to an entity that meets the
       requirements to be our successor under our affiliation agreements with
       Sprint PCS; or

     - to sell the assets or partnership interests to any third party, subject
       to specified conditions.

                        DESCRIPTION OF OUR INDEBTEDNESS

THE NORTEL CREDIT FACILITY

     GENERAL


     We entered into a credit facility effective June 10, 1999 with Nortel for
$123.0 million. We have since entered into a commitment letter with Nortel to
increase the credit facility to $250.0 million to be effective as of the closing
of this offering. 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 will be 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. This description of the
facility assumes that the terms of the commitment letter increasing the facility
are currently in place. Nortel will not fund this increase in the facility
unless various conditions are met, such as the negotiation, execution and
delivery of definitive loan documents and the absence of adverse changes
affecting us or our operations. There can be no assurance that we will fulfill
all of these conditions.


     AMOUNT AND PURPOSE OF LOANS


     The credit agreement provides for three different tranches of borrowings
evidenced by a single promissory note of $250.0 million. The Tranche A
Commitment provides for borrowings up to $167.0 million, the Tranche B
Commitment provides for borrowings up to $58.0 million and the Tranche C
Commitment provides 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. See
"Business -- Network Operations -- Nortel Equipment Agreement."



     The amount that can be borrowed under Tranche B, and the amount that can be
borrowed under Tranche C to pay third party expenses, is further limited to a
borrowing base that is computed by the administrative agent at specified times,
as provided in the credit agreement. The borrowing base is defined as 50% of the
amount paid to Nortel to purchase equipment and services used in our portion of
the Sprint PCS network. We have the option to reduce the amount of any of the
commitments, and avoid the periodic fee charged on those unborrowed amounts. Any
reduction must be at least $3.0 million. This is not a revolving credit
arrangement so reductions cannot be reinstated, except for reductions that
result from prepayments made with proceeds of our senior notes offering.


     COMMITMENT TERMINATION

     The Tranche A Commitment and the Tranche B Commitment are both scheduled to
terminate 30 months from the closing date of the credit facility. The Tranche C
Commitment is scheduled to terminate six months earlier. These commitments may
also terminate:

     - when any commitment is fully funded;


     - on the first anniversary of the closing date if we have borrowed less
       than an aggregate of $100.0 million under all three commitments by that
       date, including borrowings under the June 10, 1999 facility;



     - upon a change of control of Alamosa PCS Holdings, Inc. or Alamosa PCS,
       Inc.;


     - if we voluntarily terminate any commitment; and

     - if the administrative agent terminates one or all of the commitments due
       to the occurrence of an event of default under the credit agreement.

                                       62
<PAGE>   67


     A change in control will occur if:



     - Alamosa PCS Holdings, Inc. ceases to own all of the capital stock of
       Alamosa PCS, Inc.;



     - Alamosa PCS, Inc. ceases to own all of the capital stock of each
       subsidiary of Alamosa PCS, Inc., except that:



      - Alamosa Texas GP may own up to one percent of the ownership interests of
        Alamosa Texas;



      - Alamosa Wisconsin GP may own up to one percent of Alamosa Wisconsin; and



      - Wisconsin telephone companies may own up to three percent of Alamosa
        Wisconsin;



     - any person or group acquires more than 35% of the voting stock of Alamosa
       PCS Holdings, Inc.;



     - the directors of Alamosa PCS Holdings, Inc. who are elected or approved
       by the board of directors as of the closing of this offering, cease for
       any reason to constitute at least a majority of the board of directors of
       Alamosa PCS Holdings, Inc.; or



     - any person or group acquires more voting stock of Alamosa PCS Holdings,
       Inc. than is owned collectively by specific persons delineated in the
       credit agreement.


     SYNDICATION

     Nortel may reduce part or all of its total commitment through syndicating
the loan to other lenders. If the loan is syndicated, then the administrative
agent may change from Nortel to any successor administrative agent, acting on
behalf of the lenders in the syndicated group.

     LOANS AND INTEREST OPTIONS

     We have multiple interest rate options available under the credit
agreement:

     - we may borrow money as either a base rate loan with an interest rate
       equal to the prime or base rate of Citibank, N.A. (New York), plus 2.75%,
       or a Eurodollar loan with an interest rate equal to the London interbank
       offered rate, as adjusted for reserve requirements, plus 3.75%;

     - we may convert a base rate loan to a Eurodollar loan, or a Eurodollar
       loan to a base rate loan, at any time;

     - accrued interest is payable either on the last day of each month for base
       rate loans, the last day of the interest period for Eurodollar loans or,
       in the case of an interest period greater than three months, at three
       month intervals after the first day of such interest period;


     - we have the option to pay interest due on the loans with borrowings
       obtained under the Tranche C Commitment until the earlier of:



       - the second anniversary of the closing date;



       - the date the Tranche C Commitment is fully funded; and



       - the first anniversary of the closing date only if we have not borrowed
         at least $100.0 million under the Nortel financing by that date,
         including borrowings under the June 10, 1999 facility;


     - interest is due upon any prepayment or conversion from one interest type
       to another; and

     - all outstanding interest is due on the maturity date, which is 90 months
       after the closing date of the credit facility unless all of the
       commitments are terminated on the first anniversary of the closing date
       because we have borrowed less than $100.0 million, in which case the
       maturity date is the sixth anniversary of the closing date.

                                       63
<PAGE>   68

     PAYMENT OF PRINCIPAL

     Scheduled. At the termination of the Tranche A and Tranche B Commitments,
we must begin to repay, in quarterly installments, the principal on all
borrowings made under that commitment. A fixed percentage is due each quarter:

     - for the first eight quarters, 3.75% of the principal balance of the loan
       is due per quarter;

     - for quarters nine through twelve, 5.00% per quarter; and

     - for quarters thirteen through the maturity date, 6.25% per quarter.

Any principal that has not been paid by the maturity date is due at that time.

     Optional Prepayments. 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.

     Mandatory Prepayments. We also must make mandatory prepayments under
certain circumstances, including among others:


     - 50% of Alamosa PCS, Inc.'s excess cash flow, after March 31, 2003, or
       after March 31, 2001 if the commitments terminate on the first
       anniversary of the closing date;



     - 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; and



     - if we complete our senior notes offering, the credit agreement obligates
       us to prepay on the Nortel facility the lesser of $75.0 million or the
       amount then outstanding under that facility.


     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.

     All payments of principal, including voluntary and mandatory prepayments,
reduce the amount of the commitments by the amount of the principal paid.

     FEES


     We are required to pay:



     - an origination fee of $3.8 million, 3% of the additional $127.0 million
       loan commitment made in the amended and restated credit agreement, at the
       execution of the credit agreement; and



     - a fee on the unfunded portion of each commitment, computed by multiplying
       the average daily unused amount of each commitment by 0.75% per year.



This second fee begins to accrue on the date that is six months after the
closing date, and is payable in arrears on the last day of each calendar quarter
until the termination of the relevant commitment. We must also pay a separate,
annual agent's fee of $35,000 to the administrative agent.


     WARRANTS


     As additional consideration to Nortel for its financing commitment, we are
required to issue to Nortel warrants for 2% of our total equity as of the
closing date, on a fully-diluted basis. The warrants will spring into existence
and be exercisable by Nortel on the second anniversary of the closing date,
unless, among other options, we contribute $75.0 million of equity to Alamosa
PCS, Inc. and prepay indebtedness outstanding under the Nortel facility. We
intend to use a portion of the proceeds from our offering of senior discount
notes to prepay enough of the Nortel financing to prevent the exercise of the
warrants.


                                       64
<PAGE>   69


However, we cannot assure you that we will choose to complete our notes offering
and prepay any portion of the Nortel financing. Other options to terminate the
warrants include:



     - the assignment of a portion of the loans by Nortel to unrelated lenders;



     - the combination of a minimum amount of loan prepayments and assignments
       of loans; or



     - the achievement of a maximum ratio of senior debt to total capitalization
       as of the second anniversary of the closing date and for the two
       consecutive calendar quarters immediately prior to the second anniversary
       of the closing date.


     However, if we do not complete an additional offering of equity or debt, we
do not anticipate that the warrants will be terminated. The exercise price for
the warrants will be the price paid for our common stock in this offering.
Nortel may not transfer any of its rights with respect to the warrants before
the first anniversary of the closing date, and any warrants transferred before
the second anniversary of the closing date will be subject to the provisions
preventing exercise of the warrants. In no event may the warrants be exercised
after the eighth anniversary of the closing date.

     Nortel is entitled to multiple demand registration rights and unlimited
piggyback registration rights of the common stock warrants.

     BOARD OBSERVATION RIGHT

     So long as Nortel holds any loans or commitments under the credit
agreement, it is entitled to receive notices of all of our board and committee
meetings and to have a non-voting observer in attendance at any of those
meetings. However, Nortel will not have these rights if Alamosa PCS, Inc.'s
ratio of annualized earnings before interest, taxes, depreciation and
amortization to annualized cash interest expense plus principal payments is 1.0
to 1 or more for four consecutive quarters. Nortel may share information learned
at those meetings with employees, officers, directors and attorneys who have a
professional need to know the information, but the information must be kept
confidential by those persons. The observer may be excused from a meeting at the
request of a majority of the directors present during discussions involving
sensitive information regarding Nortel or competitors of Nortel.

     MANAGEMENT TEAM; EMPLOYMENT AGREEMENTS

     The credit agreement requires us to have an experienced telecommunications
management team reasonably satisfactory to the administrative agent, including a
chief executive officer, chief financial officer, chief operating officer and
chief technology officer. As a condition to closing the financing, key
management is required to enter into employment agreements with a minimum term
of two years, non-competition agreements and non-disclosure agreements.

     COLLATERAL

     The Nortel financing is secured by:

     - 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;

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


     - 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



     - 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.

     MINIMUM EQUITY REQUIREMENTS


     As a closing condition of the credit facility, we must raise a combined
$148.0 million in equity capital. This amount will be comprised of the net

contributed by our current stockholders. The current stockholders have
contributed an aggregate of $37.0 million.

     EVENTS OF DEFAULT

     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:

       that is not released within 30 days and the amount of the proceedings is
       greater than $500,000;

SENIOR DISCOUNT NOTES

     We intend to raise approximately $156 million through a public offering of
our senior discount notes. The senior discount notes will be unsecured
obligations, will rank equally with all our existing and future senior debt and
will rank senior to all our existing and future subordinated debt.


     The senior discount notes will be fully and unconditionally, jointly and
severally guaranteed on a senior subordinated basis by our current subsidiaries
and our future restricted subsidiaries. See "The Reorganization" regarding the
ownership structure of our subsidiaries. The guarantees will be unsecured
obligations and:


     - will be subordinate to all existing and future senior debt of each
       subsidiary guarantor, including the Nortel financing;

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

     - will be 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.

     The senior discount notes will be issued at a discount to their principal
amount and will 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 will contain
covenants limiting our ability and the ability of our subsidiaries to:

     - incur additional debt or issue preferred stock;

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

     - create liens on assets;

     - merge, consolidate or dispose of assets;

     - enter into transactions with affiliates; and

     - change lines of business.

                                       68
<PAGE>   73

     Holders of the senior discount notes will 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 proposed 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 intend to use a portion of the proceeds of that
offering to prepay $75.0 million of indebtedness outstanding under the Nortel
facility. We may decide to use the remaining proceeds of that offering to:

     - expand our existing territory;

     - build-out additional areas or accelerate coverage within our existing
       territory;

     - pursue additional wireless telecommunications business opportunities or
       acquire other wireless telecommunications businesses or assets; or

     - cover general corporate purposes.

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

     - prepay additional debt outstanding under the Nortel facility; or

     - avoid drawing additional amounts under the Nortel facility.

BOARD OF DIRECTORS


     Under the terms of Alamosa PCS, LLC's Regulations, the number of managers
to serve on the Alamosa's board of managers was fixed at nine managers. Alamo IV
had the right to appoint five of the managers and the financial members,
comprised of Rosewood Telecommunications, LLC, Tregan International Corp., West
Texas PCS LLC, Longmont PCS LLC and Yellow Rock PCS, L.P., had the right to
appoint a total of four of the managers. If Alamo IV's percentage interest in
Alamosa PCS, LLC fell below 45% then the number of managers it was able to
appoint also fell in a corresponding manner. Likewise, if the financial members
combined percentage interest in Alamosa PCS, LLC fell below 33% then the number
of managers they were able to appoint as a group also fell in a corresponding
manner. Neither Alamo IV's number of appointments nor the financial members'
number of appointments increased as a result of a decrease in the other group's
percentage interest. Any remaining manager position was to be filled by a
manager elected by a majority of the members of Alamosa PCS, LLC. As a result of
Alamo IV's dissolution in November 1999, Alamo IV no longer holds any right to
appoint managers, but the former members of Alamo IV are currently still able to
act together to appoint five of the managers. Prior to the closing of this
offering, Alamosa PCS, LLC will be reorganized and the current managers of
Alamosa PCS, LLC will become directors of Alamosa PCS Holdings, Inc. Upon this
reorganization, the former members of Alamo IV and the financial members will
lose their right to appoint any future directors. For further information on the
reorganization, see "The Reorganization."


     After the reorganization, our board of directors will be fixed at nine
members. We will divide our board of directors into three classes. Ray M. Clapp,
Jr., Jimmy White and Thomas Hyde constitute Class I and will stand for election
at the annual meeting of stockholders to be held in 2001. Michael R. Budagher,
Schuyler B. Marshall and Reagan W. Silber constitute Class II and will stand for
election at the annual meeting of stockholders to be held in 2002. Tom M.
Phelps, David E. Sharbutt, and Scotty Hart constitute Class III and will stand
for election at the annual meeting of stockholders to be held in 2003. After the
initial term following the offering, directors in each class will serve for a
term of three years, or until his or her successor has been elected and
qualified and will be compensated at the discretion of the board of directors.
Executive officers are ordinarily elected annually and serve at the discretion
of the board of directors.

     COMPENSATION OF DIRECTORS

     Currently, we do not compensate our directors. No director who is an
employee of Alamosa 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 David 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.

     Following the closing of this offering, pursuant to the 1999 Long Term
Incentive Plan, each of our directors who is an independent director because he
or she is not an officer or employee of Alamosa will automatically receive an
initial option to purchase 28,000 shares of our common stock upon the closing of
this offering or on the date he or she becomes one of our directors. 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 this
initial public offering and our debt offering. The initial option becomes
exercisable with respect to 100% of the shares covered thereby six months after
the date of grant and 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.

     BOARD COMMITTEES


     Our board of directors has established five committees. They are the:

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 "Certain Relationships and
Related Transactions" for more details on 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 represents a company called Harlamo LLC
that is a member of Alamo IV LLC and he also serves as Vice President of Alamo
IV LLC. Thomas Hyde, who is one of our directors, along with Scotty Hart and
Jimmy White, serve 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:

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

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

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

     - 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:

     - Base salary;


     - Annual incentive compensation, the receipt of which is based on:



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



          - significant individual contributions; and


     - 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 $302,200 for fiscal 1999, representing a
salary of $175,000, a bonus of $120,000 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:



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



     - 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.

EXECUTIVE COMPENSATION

     The following table presents summary information with respect to the

W. Don Stull during the period from the inception of Alamosa, July 16, 1998, to
December 31, 1998 and for the year ended December 31, 1999. We had no chief
executive officer during the period from inception, July 16, 1998, to December
31, 1998. Mr. Brantley, as Chief Operating Officer, acted in a capacity similar
to that of chief executive officer during that period. David E. Sharbutt became
our chief executive officer effective as of October 1, 1999, and has served as
our chief executive officer since that time.

BENEFIT PLANS

     1999 LONG TERM INCENTIVE PLAN

     The 1999 Long Term Incentive Plan has been adopted by our board of
directors and stockholders. The purpose of the plan is to attract and retain the
services of our key management employees, outside directors and consultants by
providing those persons with a proprietary interest in us. The plan allows us to
provide that proprietary interest through the grant of:

     - incentive stock options;

     - nonqualified stock options;

     - tandem and independent stock appreciation rights;

     - stock bonuses; and


     - 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 this
offering to purchase 6,028,000 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 485,000 shares of our common stock
with an exercise price of $1.15 per share to two of our executive officers.



     The option plan will be administered by our board of directors or by a
stock option plan committee appointed by our board of directors, which will be
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:

     - the award period;

     - the date of grant;

     - the vesting period; and

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

     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 or unless determined otherwise by our board of directors or the
committee.


                                       78
<PAGE>   83


     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:



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



     - 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;



     - 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



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



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



      - 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:



     - 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



     - 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.

covenant. Further, Mr. Stull has agreed not to disclose any of our confidential

to Mr. Stull to convert those options into three series of options, each series
consisting of an option to purchase 48,500 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

death or disability he shall be vested in a fractional portion of the series
options that would have vested on the October 29 immediately following such
death or disability based on the number of months 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.

                 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. The members of Alamo
IV LLC plan to dissolve Alamo IV LLC and distribute 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 will be eliminated when we reorganize from a limited
liability company to a holding company structure prior to closing of this
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 will be terminated prior to the closing
of this 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.


     - 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 for these
       services during 1998.

     - On November 20, 1998, we entered into a special service contract
       effective as of September 20, 1998 with CHR Solutions, who provided us
       with marketing and operations consulting services for a maximum amount of
       $100,000, excluding taxes.

     - As of April 6, 1999, we entered into a telecommunications service
       agreement with Tech Telephone Company Limited Partnership, an affiliate
       of CHR Solutions, to install and provide DS1 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 successive 30-day terms until
       terminated by either party. The total amount of fees paid through the end
       of 1999 was approximately $395,000.


     - As of April 9, 1999, we entered into a data communications services
       contract with CHR Solutions to perform design and implementation services
       for us in connection with our wide area network and local area networks
       for a maximum fee of $262,040, excluding taxes. The agreement lasts until
       the project is completed, unless either party terminates it earlier for
       cause.

       TechTel Communications Corporation, an affiliate of CHR Solutions,

       and services for Alamosa in Lubbock. This is a standard agency agreement
       identical with numerous other agreements between Alamosa and other third

       one year.

       $81,000. 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 Solutions to perform business planning and consulting services and a
       feasibility study in selected areas of our territory for an estimated
       probable cost of $200,000, 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 Solutions to provide us with radio frequency "drive testing" to
       predict the propagation characteristics of given areas in our territory
       for an estimated probable cost of $62,085, excluding taxes. This
       agreement lasts until the project is completed, unless either party
       terminates it earlier.


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
is for five years, with automatic renewal for three additional terms of five
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
agreement was entered into the Vice Chairman, Chief Operating Officer and a
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.

SALE OF COMMON STOCK IN THIS OFFERING TO CURRENT STOCKHOLDERS

     As part of this sale of our common stock, the underwriters have agreed to
reserve a maximum of 10% of the shares of our common stock to be sold in this
offering for sale to our current stockholders at a price per share equal to the
public offering price less the underwriting discount. The underwriters will not
be entitled to any discount or commission on these shares and the proceeds to us
will be the same as if the shares were sold to the general public. However, the
number of shares of common stock available for sale to the general public will
be reduced to the extent of sales of shares to our current stockholders.

OTHER RELATED PARTY TRANSACTIONS


     In November 1998, we entered into a lease agreement to lease space for
telephone switching equipment in Albuquerque with SASR Limited Partnership, 50%
owned by Michael Budagher, one of our directors and a manager of West Texas PCS,
LLC, one of our stockholders. The lease has a term of five years commencing
January 1, 1999, with two optional five year terms. The lease provides for
monthly payments aggregating to $18,720 a year, as well as a pro rata portion of
real estate taxes on the property, subject to adjustment.


     In connection with our distribution and sales of Sprint PCS wireless
communications equipment, on December 28, 1998, we entered into a build-to-suit
lease agreement for a retail store in Lubbock with Lubbock HLH, Ltd.,
principally owned by Scotty Hart, one of our directors and the General Manager
of South Plains Advanced Communications & Electronics, Inc. South Plains is one
of our stockholders. This lease, as amended, has a term of 15 years commencing
on July 1, 1999 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.


     On April 23, 1999, we entered into a note with our Chief Operating Officer,
Jerry W. Brantley, evidencing a loan to Mr. Brantley in the amount of $100,000.
This loan was made pursuant to Mr. Brantley's employment agreement, which
provides that Mr. Brantley is entitled to receive this loan upon his relocation
from the San Antonio, Texas vicinity. The loan matures in April 2014 and accrues
interest at an annual rate of 7.75%. Principal and interest is payable in
monthly installments of $1,052.91 each beginning April 23, 2000. As of December
31, 1999, the entire $100,000 was still outstanding on the loan.


     We believe that the terms of each of the transactions described above,
taken as a whole, were no less favorable than we could have obtained from
unaffiliated third parties.

             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:

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

     - grant or deny wireless personal communications services license renewals;

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

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

     - establish access and universal service funding provisions;

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

     - 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.

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

                                       89
<PAGE>   94

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 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. In addition to
revoking the licenses, the Federal Communications Commission could impose
monetary penalties on us.

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:


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



     - 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 services, providers for the termination
of traffic. Using these new rules, we will negotiate 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 us and Sprint PCS in various markets.
However, to date, wireless
                                       90
<PAGE>   95

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 services providers to implement 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 us, Sprint PCS
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 1 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 1 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:

     - 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

     - 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.

                                       91
<PAGE>   96

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.

     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 us, Sprint PCS 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

     We 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 the 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 a "universal service" program 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 serve
substantial rural areas, we are likely to obtain revenues in the future from
federal and state universal service support funds that are much greater than the
contributions we will pay.

                                       92
<PAGE>   97

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 us, Sprint PCS 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:



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



     - 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 we 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.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL


     The following summarizes all of the material terms and provisions of our
capital stock as they are contemplated to be as of the closing of this offering.
We have 300,000,000 shares of authorized capital stock, including 290,000,000
shares of common stock, par value $0.01 per share and 10,000,000 shares of
preferred stock, par value $0.01 per share. As of December 10, 1999, assuming
the reorganization of our business form into a holding company structure, and
the simultaneous exchange of limited liability company membership interests into
shares of common stock, there were 48,500,000 shares of common stock and no
shares of preferred stock issued and outstanding. As of that date, there would
have been approximately 29 holders of record of the outstanding shares of common
stock.


COMMON STOCK

     The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of stockholders and do not have any
cumulative rights. Subject to the rights of the holders of any series of
preferred stock, holders of common stock are entitled to receive ratably those
dividends as may be declared by the board of directors out of legally available
funds. However, our credit agreement with Nortel prohibits the payment of
dividends of common stock. Holders of shares of common stock have no preemptive,
conversion, redemption, subscription or similar rights. All shares of common
stock, when validly issued and fully paid, will be non-assessable. If we
liquidate, dissolve or wind up, the holders of shares of common stock are
entitled to share ratably in the assets which are legally available for
distribution, if any, remaining after the payment or provision for the payment
of all debts and other liabilities and the payment and setting aside for payment
of any preferential amount due to the holders of shares of any series of
preferred stock.

PREFERRED STOCK

     Under our certificate of incorporation, the board of directors is
authorized, subject to limitations prescribed by law, without further
stockholder approval, from time to time to issue up to an aggregate of
10,000,000 shares of preferred stock. The preferred stock may be issued in one
or more series. Each series may have different rights, preferences and
designations and qualifications, limitations and restrictions that may be
established by our board of directors without approval from the stockholders.
These rights, designations and preferences include:

     - number of shares to be issued;

     - dividend rights;

     - dividend rates;

     - conversion rights;

     - voting rights;

     - liquidation preferences; and

     - terms of redemption.

     If our board of directors decides to issue any preferred stock, it may
discourage or make more difficult a merger, tender offer, business combination
or proxy contest, assumption of control by a holder of a large block of our
securities or the removal of incumbent management, even if these events were
favorable to the interests of stockholders. The board of directors, without
stockholder approval, may issue preferred stock with voting and conversion
rights and dividend and liquidation preferences which may adversely affect the
holders of common stock.

                                       94
<PAGE>   99

     The Series A preferred stock described under "Stockholder Rights Plan"
below is a series of preferred stock that will be authorized by our board of
directors in connection with a stockholder rights plan.

WARRANTS


     As additional consideration to Nortel for its financing commitment, we are
required to issue to Nortel warrants for 2% of our total equity as of the
closing date, on a fully-diluted basis. The warrants will spring into existence
and be exercisable by Nortel on the second anniversary of the closing date,
unless, among other options, we contribute $75.0 million of equity to Alamosa
PCS, Inc. and prepay indebtedness outstanding under the Nortel facility. We
intend to use a portion of the proceeds from our offering of senior discount
notes to prepay enough of the Nortel financing to prevent the exercise of the
warrants. However, we cannot assure you that we will choose to complete our
notes offering or that we will prepay any portion of the Nortel financing. Other
options to terminate the warrants include:



     - the assignment of a portion of the loans by Nortel to unrelated lenders;



     - a minimum combination of loan prepayments and assignment of the loans; or



     - a maximum ratio of senior debt to total capitalization as of the second
       anniversary of the closing date and for the two consecutive calendar
       quarters immediately prior to the second anniversary of the closing date.


However, if we do not complete an additional offering of equity or debt, we do
not anticipate that the warrants will be terminated. The exercise price for the
warrants will be the price paid for our common stock in this offering. Nortel
may not transfer any of its rights with respect to the warrants before the first
anniversary of the closing date, and any warrants transferred before the second
anniversary of the closing date will be subject to the provisions preventing
exercise of the warrants. In no event may the warrants be exercised after the
eighth anniversary of the closing date.

     Nortel is entitled to multiple demand registration rights and unlimited
piggyback registration rights of the common stock warrants.

DELAWARE LAW

     The acquisition of Alamosa by means of a tender offer, a proxy contest or
otherwise and the removal of incumbent officers and directors may be more
difficult due to provisions of Delaware law. These provisions are expected to
discourage types of coercive takeover practices and inadequate takeover bids and
to encourage persons seeking to acquire control of Alamosa to first negotiate
with us. We believe the increased protection of our potential ability to
negotiate with the proponent of an unfriendly or unsolicited proposal to acquire
or restructure Alamosa outweighs the disadvantages of discouraging these
proposals because, among other things, negotiation of these proposals could
result in an improvement of the terms of any of these proposals.

     We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. In general, the statute prohibits us from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date that the person became an interested stockholder, unless:

     - prior to the date that the person became an interested stockholder, the
       transaction or business combination that resulted in the person becoming
       an interested stockholder is approved by the board of directors;

     - upon consummation of the transaction that resulted in the stockholder
       becoming an interested stockholder, the interested stockholder owns at
       least 85% of our outstanding voting stock; or

     - on or after that date, the business combination is approved by our board
       of directors and by the affirmative vote of at least 66 2/3% of our
       outstanding voting stock that is not owned by the interested stockholder.

Generally, a "business combination" includes a merger, asset or stock sale, or
other transaction resulting in a financial benefit to the stockholder. Subject
to certain exceptions, an "interested stockholder" is a person who, together
with that person's affiliates and associates, owns or within the previous three
years, did own 15% or more of our voting stock.


PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND BYLAWS THAT MAY PREVENT
TAKEOVERS


     Our certificate of incorporation contains provisions that may delay, defer
or prevent a change in control of Alamosa and make removal of our management
more difficult.


     Our certificate of incorporation provides for the division of the board of
directors into three classes, as nearly equal in size as possible, with each
class beginning its three year term in a different year. Our certificate of
incorporation also provides that only the board of directors may fix the number
of directors. Our bylaws provide that a stockholder may nominate directors only
if the stockholder delivers written notice to us not less than 45 days or more
than 75 days before the first anniversary of the date on which we first mailed
our proxy materials for the preceding year's annual meeting. If the date of the
annual meeting is advanced more than 30 days before or delayed more than 30 days
after the anniversary of the preceding year's annual meeting, then we must
receive the stockholder's notice not after the later of the ninetieth day before
the annual meeting or the tenth day after the day the public announcement of the
date of the annual meeting is made.



     Our certificate of incorporation provides that any newly created
directorship resulting from an increase in the number of directors or a vacancy
on the board of directors may be filled only by vote of a majority of the
remaining directors then in office, even if less than a quorum. Under no
circumstances will our stockholders fill any newly created directorships.
Directors elected to fill a vacancy or by reason of an increase in the number of
directors will hold office until the annual meeting of stockholders at which the
term of office of the class to which they have been elected expires. Directors
may be removed from office only for cause and only by the affirmative vote of
80% of the then outstanding shares of stock entitled to vote on the matter.


     Our certificate of incorporation provides that any action required or
permitted to be taken by our stockholders may be taken only at a duly called
annual or special meeting of the stockholders, and may not be taken by written
consent of the stockholders. Special meetings may be called only by the Chairman
of the board of directors, if there is one, the President, the board of
directors or the holders of not less than a majority of the then outstanding
shares entitled to vote generally in an election of directors. These provisions
could have the effect of delaying until the next annual stockholders meeting
stockholder actions that are favored by the holders of a majority of the
outstanding voting securities. These provisions may also discourage another
person or entity from making an offer to stockholders for the common stock. This
is because the person or entity making the offer, even if it acquired a majority
of our outstanding voting securities, would be unable to call a special meeting
of the stockholders and would further be unable in most situations to obtain
unanimous written consent of the stockholders. As a result, any meeting as to
matters they endorse, including the election of new directors or the approval of
a merger, would have to wait for the next duly called stockholders meeting.

     Our certificate of incorporation also contains fair price provisions
designed to provide safeguards for stockholders when a stockholder owning 20% or
more of our voting stock, referred to as an interested stockholder, or that
interested stockholder's affiliates or associates, attempts to effect a business
combination with Alamosa.

                                       96
<PAGE>   101

Events that are deemed business combinations include:

     - any merger or consolidation of Alamosa involving an interested
       stockholder;

     - specified dispositions of assets, cash flow or earning power of Alamosa
       to an interested stockholder, any issuance of our securities to an
       interested stockholder or our entering into loans or other arrangements
       involving an interested stockholder, in each case, meeting specified
       threshold amounts;

     - the adoption of any plan of liquidation or dissolution of Alamosa; and

     - any issuance or reclassification of our securities having the effect of
       increasing the proportionate share of ownership of an interested
       stockholder.


     Regarding the 20% threshold for the definition of interested stockholder,
persons who were stockholders in our company before the date of this sale of our
common stock may enter into voting agreements with each other, without being
deemed the beneficial owner of securities owned by the other parties to the
voting agreements, only if the voting agreements:



     - were approved by our board of directors prior to the time they were
       entered into;



     - do not govern the voting of our common stock in matters other than the
       election of members of our board of directors; and



     - do not govern the voting of our common stock held by persons other than
       persons who were stockholders in our company before the date of this sale
       of our common stock.


In general, a business combination between Alamosa and an interested stockholder
must be approved by the affirmative vote of the holders of 80% of our
outstanding voting stock, excluding voting stock owned by such interested
stockholder, unless the transaction is approved by a majority of the members of
the board of directors who are not interested stockholders and who are not
affiliated with the interested stockholder. Minimum price and form consideration
requirements must also be satisfied. See also "-- Delaware Law."


     Delaware Law provides that the affirmative vote of a majority of the shares
entitled to vote on any matter is required to amend a corporation's certificate
of incorporation or bylaws, unless the corporation's certificate of
incorporation or bylaws, as the case may be, requires a greater percentage. Our
certificate of incorporation requires the affirmative vote of the holders of at
least 80% of the outstanding voting stock to amend or repeal any of the
provisions of the certificate of incorporation or bylaws described above. Except
as otherwise provided by law, holders of our common stock are not entitled to
vote on any amendment to our certificate of incorporation that changes the
powers, preferences, rights or other terms of an outstanding series of our
preferred stock, if the holders of the affected series of preferred stock are
entitled to vote on the proposed amendment. The bylaws may be amended or
repealed by the board of directors, except if the bylaw provisions affect
provisions of the certificate of incorporation or bylaws described above, then
the affirmative vote of the holders of at least 80% of the outstanding voting
stock is required. The 80% stockholder vote would be in addition to any separate
vote that each class of preferred stock is entitled to that might in the future
be required in accordance with the terms of any preferred stock that might be
outstanding at the time any amendments are submitted to stockholders.


     The foregoing provisions, together with the ability of the board of
directors to issue preferred stock without further stockholder action, may delay
or frustrate the removal of incumbent directors or the completion of
transactions that would be beneficial, in the short term, to our stockholders.
The provisions may also discourage or make more difficult a merger, tender
offer, other business combination or proxy contest, the assumption of control by
a holder of a large block of our securities or the removal of incumbent
management, even if these events would be favorable to the interests of our
stockholders.

     The certificate of incorporation requires us to indemnify our directors and
officers to the fullest extent permitted by law. In addition, as permitted by
Delaware law, the certificate of incorporation provides that no director will be
liable to us or our stockholders for monetary damages for breach of certain
fiduciary

                                       97
<PAGE>   102

duties as a director. The effect of this provision is to restrict our rights and
the rights of our stockholders in derivative suits to recover monetary damages
against a director for breach of certain fiduciary duties as a director, except
that a director will be personally liable for:

     - acts or omissions not in good faith for which involve intentional
       misconduct or a knowing violation of law;

     - the payment of dividends or the redemption or purchase of stock in
       violation of Delaware law;

     - any breach of the duty of loyalty to Alamosa or our stockholders; or

     - any transaction from which the director derived an improper personal
       benefit.

CERTAIN PROVISIONS OF THE SPRINT PCS AGREEMENTS

     Pursuant to our affiliation agreements with the Sprint PCS, under specific
circumstances and without further stockholder approval, Sprint PCS may purchase
our operating assets or capital stock for 72% or 80% of the "entire business
value" of Alamosa, which includes the value of the spectrum licenses, business
operations and other assets more fully described in "Our Affiliation Agreements
with Sprint PCS -- The Management Agreement -- Determination of Entire Business
Value." In addition, Sprint PCS must approve any change of control of our
ownership and consent to any assignment of our affiliation agreements with
Sprint PCS. 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 may limit our ability to sell the business and may have a substantial
anti-takeover effect.

STOCKHOLDER RIGHTS PLAN

  Rights and rights certificates

     Our board of directors currently expects to adopt a stockholder rights plan
at or prior to the closing of this offering. On the date the stockholder rights
plan is adopted, we will declare a dividend of one right for each share of
common stock outstanding. A right will also attach to each share of common stock
issued at the closing of the offering and each share of common stock issued
subsequent to the closing of the offering. Each right, when exercisable,
entitles the holder to purchase from us one one-thousandth of a share of Series
A Preferred Stock at a purchase price of $     per one one-thousandth of a
share, subject to adjustment. Each fractional share of the Series A Preferred
Stock will essentially be the economic equivalent of one share of common stock.

     A stockholder rights plan is designed to deter coercive takeover tactics
and to otherwise encourage third parties interested in acquiring us to negotiate
with our board of directors. The stockholder rights plan achieves these goals by
significantly diluting the ownership interest of a person who acquires a
specified percentage of common stock.

     Initially, the rights will be attached to all certificates representing
outstanding shares of common stock and will be transferred with and only with
such certificates. The rights will separate from the common stock and become
exercisable upon the earlier to occur of:

     - the close of business on the tenth business day after the public
       announcement that a person or group of persons has acquired 20% or more
       of our outstanding common stock, except in connection with an offer
       approved by our board of directors; or

     - the close of business on the tenth business day after the commencement
       of, or announcement of an intention to commence a tender offer or
       exchange offer that would result in a person or group of persons
       acquiring 20% or more of our outstanding common stock.


     A person or group of persons will be considered to have acquired beneficial
ownership of common stock if they have the power to vote or direct the voting of
the common stock. Stockholders in existence


                                       98
<PAGE>   103


prior to the date of this sale of our common stock may enter into voting
agreements with each other only, at any time, without being deemed the
beneficial owner of securities owned by the other parties to the voting
agreements, if the voting agreements:



     - were approved by our board of directors prior to the time they were
       entered into;



     - do not govern the voting of our common stock regarding matters other than
       the election of members of our board of directors; and



     - do not govern the voting of our common stock held by persons other than
       stockholders in existence prior to the date of this sale of our common
       stock.


  Expiration of rights

     The rights will expire at the close of business on the tenth anniversary of
the date of issuance, unless we redeem or exchange the rights before that date
or amend the stockholder rights plan to extend the term of the rights.

  Flip-in right

     If any person or group of persons acquires 20% or more of our outstanding
common stock, each holder of a right, other than the acquiring person, will have
the right to receive the number of shares of common stock, or in certain
circumstances, cash, property or other securities of Alamosa, having a value
equal to two times the purchase price of the right. The acquiring person's
rights will automatically become null and void in that event. In other words,
the stockholders other than the acquiring person will be able to buy common
stock at half price.

  Flip-over right

     If at any time after a person or group of persons acquires 20% or more of
our outstanding common stock and the following occurs:

     - we effect a merger or other business combination in which we are not the
       surviving corporation;

     - we are the surviving corporation in a consolidation, merger or similar
       transaction in which our shares of common stock are changed into or
       exchanged for other securities; or

     - we sell or otherwise transfer more than 50% of our assets, cash flow or
       earning power,

then each holder of a right, except a person who has acquired beneficial
ownership of 20% or more of the outstanding common stock, may purchase, upon the
exercise of each right at the then-current purchase price, that number of shares
of common stock of the acquiring company with a market value equal to two times
the purchase price of the right. In other words, the stockholders other than the
acquiring person will be able to buy common stock of the acquiring company at
half price.

  Adjustments

     The purchase price and the number of shares of Series A preferred stock or
other securities issuable upon exercise of the rights may be adjusted to prevent
dilution upon:

     - stock dividends, subdivisions, combinations or reclassifications of the
       Series A preferred stock;

     - below market issuances of rights or warrants to subscribe for or convert
       into Series A preferred stock; or

     - distributions to holders of the Series A preferred stock of evidence of
       indebtedness, cash, excluding regular quarterly cash dividends, assets,
       excluding dividends payable in Series A preferred stock, or subscription
       rights or warrants.

                                       99
<PAGE>   104

  Exchange of rights

     After a person or group of persons acquires 20% of our outstanding common
stock but before that person or group beneficially owns 50% or more of our
common stock, we may, at our option, exchange the rights at an exchange ratio of
one-half the number of shares of common stock, Series A preferred stock, or
other property for which a right is exercisable immediately prior to our
decision to exchange the rights, subject to adjustment. Rights held by an
acquiring person are not entitled to these exchange rights. In that event, the
stockholders other than the acquiring person would receive common stock in
exchange for their rights.

  Redemption of rights

     At any time before a person or group of persons acquires 20% or more of our
outstanding common stock, we may redeem the rights at a price of $0.001 per
right. Upon the effective date of the redemption of the rights, the rights will
terminate and the rights holders will only be entitled to receive the $0.001
redemption price.

  Rights as a stockholder

     Until a right is exercised, the rights will not entitle the holder to the
rights as an Alamosa stockholder, including, without limitation, the right to
vote or to receive dividends.

  The preferred stock

     The terms of the Series A preferred stock will be contained in a
Certificate of Designations, Rights and Preferences filed with the Delaware
Secretary of State and attached as an exhibit to the Stockholder Rights Plan,
which is filed as an exhibit to the registration statement.

  Anti-takeover effects

     The rights will have certain anti-takeover effects. The rights will cause
substantial dilution to any person or group that attempts to acquire us without
the approval of our board of directors. As a result, the overall effect of the
rights may be to make more difficult a merger, tender offer, other business
combination or proxy contest, even if such event would be favorable to the
interest of stockholders.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is ChaseMellon
Shareholder Services, Dallas, Texas.

LISTING

     Application will be made to list the shares of common stock on the Nasdaq
National Market under the symbol "APCS."

                        SHARES ELIGIBLE FOR FUTURE SALE

     Prior to this offering, there has been no market for the common stock.
Future sales of substantial amounts of common stock in the public market could
adversely affect market prices of the common stock prevailing from time to time.
Furthermore, because only a limited number of shares will be available for sale
shortly after the consummation of this offering due to contractual and legal
restrictions on resale, as described below, sales of substantial amounts of
common stock in the public market after the restrictions lapse could adversely
affect the prevailing market price of the common stock and our ability to raise
equity capital in the future.

     Upon completion of this offering, we will have outstanding an aggregate of
59,214,000 shares of common stock, assuming no exercise of the underwriters'
over-allotment option. Of these shares, all of the
                                       100
<PAGE>   105

shares sold in this offering will be freely tradeable without restriction or
further registration under the Securities Act, except that any shares purchased
by our affiliates may generally only be sold in compliance with the limitations
of Rule 144 described below.

SALES OF RESTRICTED SHARES; OPTIONS

     All of the shares of common stock sold in this offering will be freely
tradeable under the Securities Act, unless purchased by our "affiliates," as the
Securities Act defines that term. In general, under Rule 144 as currently in
effect, a person or persons whose shares are aggregated, including an affiliate,
who has beneficially owned restricted stock for at least one year is entitled to
sell, within any three-month period, a number of shares of stock that does not
exceed the greater of:

     - one percent of the then outstanding shares of common stock, or

     - the average weekly trading volume in the common stock during the four
       calendar weeks preceding the date on which notice of that sale is filed.

     In addition, under Rule 144(k), a person who is not an affiliate and has
not been an affiliate for at least three months prior to the sale and who has
beneficially owned shares of restricted stock for at least two years may resell
those shares without compliance with the foregoing requirements. In meeting the
one and two year holding periods described above, a holder of restricted stock
can include the holding periods of prior owners who were not an affiliate.

     Additional shares of common stock are available for future grants under our
1999 Long Term Incentive Plan. See "Management -- Benefit Plans -- 1999 Long
Term Incentive Plan." We intend to file one or more registration statements on
Form S-8 under the Securities Act to register all shares of common stock subject
to outstanding stock options and common stock issuable pursuant to our benefit
plans that do not qualify for an exemption under Rule 701 from the registration
requirements of the Securities Act. We expect to file these registration
statements as soon as practicable following the closing of this offering, and
these registration statements are expected to become effective upon filing.
Shares covered by these registration statements will be eligible for sale in the
public markets subject to the lock-up agreements, to the extent applicable.

LOCK-UP AGREEMENTS


     We, our members of senior management and directors, and some of our current
stockholders have agreed, pursuant to the lock-up agreements that, during the
period beginning from the date of this prospectus and continuing and including
the date 180 days after the date of this prospectus, they will not, directly or
indirectly, offer, pledge, sell, or otherwise dispose of any shares of capital
stock, including but not limited to the filing, or participation in the filing,
of a registration statement with the Securities and Exchange Commission in
respect of, or establish or increase a put equivalent position or liquidate or
decrease a call equivalent position within the meaning of Section 16 of the
Securities Exchange Act of 1934, as amended, and the rules and regulations of
the Securities and Exchange Commission promulgated thereunder with respect to,
any shares of capital stock or any securities convertible into, or exercisable
or exchangeable for such capital stock, or publicly announce an intention to
effect any such a transaction, without the prior written consent of Salomon
Smith Barney Inc. Salomon Smith Barney Inc. has informed the Company that it has
no current intentions of releasing any shares subject to the lock-up agreements.
Any determination by Salomon Smith Barney Inc. to release any shares subject to
the lock-up agreements would be based on a number of factors at the time of
determination, including the market price of the common stock, the liquidity of
the trading market for the common stock, general market conditions, the number
of shares proposed to be sold, and the timing, purpose and terms of the proposed
sale. There are no exceptions to the lock-up, except for shares disposed of as
bona fide gifts to persons who also enter into lock-up agreements which
terminate 180 days after the date of this prospectus.



     Following the lock-up period, approximately 48,500,000 shares of common
stock, excluding shares underlying options immediately exercisable upon
completion of this offering, will become eligible for sale, subject to
compliance with Rule 144 of the Securities Act as described above.

                IMPORTANT UNITED STATES FEDERAL TAX CONSEQUENCES
                    OF OUR COMMON STOCK TO NON-U.S. HOLDERS

     This is a general discussion of United States federal tax consequences of
the acquisition, ownership, and disposition of our common stock by a holder
that, for U.S. federal income tax purposes, is not a U.S. person as we define
that term below. A holder of our common stock who is not a U.S. person is a
non-U.S. holder. We assume in the discussion that you will hold our common stock
issued pursuant to the offering as a capital asset, which generally, is property
held for investment. We do not discuss all aspects of U.S. federal taxation that
may be important to you in light of your individual investment circumstances,
such as special tax rules that would apply to you, for example, if you are a
dealer in securities, financial institution, bank, insurance company, tax-exempt
organization, partnership or owner of more than 5% of our common stock. Our
discussion is based on current provisions of the Internal Revenue Code of 1986,
as amended, Treasury regulations, judicial opinions, published positions of the
U.S. Internal Revenue Service and other applicable authorities, all as in effect
on the date of this prospectus and all of which are subject to differing
interpretations or change, possibly with retroactive effect. We have not sought,
and shall not seek, any ruling from the IRS with respect to the tax consequences
discussed in this prospectus, and there can be no assurance that the IRS will
not take a position contrary to the tax consequences discussed below or that any
position taken by the IRS would not be sustained. We urge you to consult your
tax advisor about the U.S. federal tax consequences of acquiring, holding, and
disposing of our common stock, as well as any tax consequences that may arise
under the laws of any foreign, state, local, or other taxing jurisdiction.

     For purposes of this discussion, a U.S. person means any one of the
following:

     - a citizen or resident of the U.S.

     - a corporation, partnership, or other entity created or organized in the
       U.S. or under the laws of the U.S. or of any political subdivision of the
       U.S.

     - an estate, the income of which is includable in gross income for U.S.
       federal income tax purposes regardless of its source

     - a trust, the administration of which is subject to the primary
       supervision of a U.S. court and that has one or more U.S. persons who
       have the authority to control all substantial decisions of the trust

DIVIDENDS

     Dividends paid to a non-U.S., holder will generally be subject to
withholding of U.S. federal income tax at the rate of 30%. If, however, the
dividend is effectively connected with the conduct of a trade or business in the
U.S. by the non-U.S. holder, the dividend will be subject to U.S. federal income
tax imposed on net income on the same basis that applies to U.S. persons
generally, and, for corporate holders under certain circumstances, the branch
profits tax. Non-U.S. holders should consult any applicable income tax treaties
that may provide for a reduction of, or exemption from, withholding taxes. For
purposes of determining whether tax is to be withheld at a reduced rate as
specified by a treaty, we generally will presume that dividends we pay on or
before December 31, 2000, to an address in a foreign country are paid to a
resident of that country.

     Under recently finalized Treasury regulations, which in general apply to
dividends that we pay after December 31, 2000, to obtain a reduced rate of
withholding under a treaty, a non-U.S. holder generally will be required to
provide certification as to that non-U.S. holder's entitlement to treaty
benefits. These regulations also provide special rules to determine whether, for
purposes of applying a treaty, dividends that we pay to a non-U.S. holder that
is an entity should be treated as paid to holders of interests in that entity.

<PAGE>   107

GAIN ON DISPOSITION

     A non-U.S. holder will generally not be subject to United States federal
income tax, including by way of withholding, on gain recognized on a sale or
other disposition of our common stock unless any one of the following is true:

     - the gain is effectively connected with the conduct of a trade or business
       in the U.S. by the non-U.S. holder;

     - the non-U.S. holder is a nonresident alien individual present in the U.S.
       for 183 or more days in the taxable year of the disposition and other
       requirements are met;

     - the non-U.S. holder is subject to tax pursuant to provisions of the U.S.
       federal income tax law applicable to certain U.S. expatriates; and

     - we are or have been during certain periods a "United States real property
       holding corporation" for U.S. federal income tax purposes.

     If we are or have been a United States real property holding corporation, a
non-U.S. holder will generally not be subject to U.S. federal income tax on gain
recognized on a sale or other disposition of our common stock provided that:

     - the non-U.S. holder does not hold, and has not held during certain
       periods, directly or indirectly, more than 5% of our outstanding common
       stock; and

     - our common stock is and continues to be traded on an established
       securities market for U.S. federal income tax purposes.

We believe that our common stock will be traded on an established securities
market for this purpose in any quarter during which it is included for quotation
on the Nasdaq National Market.

     If we are or have been during certain periods a U.S. real property holding
corporation and the above exception does not apply, a non-U.S. holder will be
subject to U.S. federal income tax with respect to gain realized on any sale or
other disposition of our common stock as well as to a withholding tax, generally
at a rate of 10% of the proceeds. Any amount withheld pursuant to a withholding
tax will be creditable against a non-U.S. holder's federal income tax liability.

     Gain that is effectively connected with the conduct of a trade or business
in the U.S. by the non-U.S. holder will be subject to the U.S. federal income
tax imposed on net income on the same basis that applies to U.S. persons
generally, and, for corporate holders under certain circumstances, the branch
profits tax, but will generally not be subject to withholding. Non-U.S. holders
should consult any applicable income tax treaties that may provide for different
rules.

UNITED STATES FEDERAL ESTATE TAXES

     Our common stock that is owned or treated as owned by an individual who is
not a citizen or resident of the U.S., as specially defined for U.S. federal
estate tax purposes, on the date of that person's death will be included in his
or her estate for U.S. federal estate tax purposes, unless an applicable estate
tax treaty provides otherwise.

INFORMATION REPORTING AND BACKUP WITHHOLDING

     Generally, we must report annually to the IRS and to each non-U.S. holder
the amount of dividends that we paid to a holder, and the amount of tax that we
withheld on those dividends. This information may also be made available to the
tax authorities of a country in which the non-U.S. holder resides.

                                       103
<PAGE>   108

     Under current U.S. Treasury regulations, U.S. information reporting
requirements and backup withholding tax will generally not apply to dividends
that we pay on our common stock to a non-U.S. holder at an address outside the
U.S. Payments of the proceeds of a sale or other taxable disposition of our
common stock by a U.S. office or a broker are subject to both backup withholding
at a rate of 31% and information reporting, unless the holder certifies as to
its non-reporting requirements. Information reporting, but not backup
withholding tax, will also apply to payments of the proceeds of a sale or other
taxable disposition of our common stock by foreign offices of U.S. brokers or
foreign brokers with certain types of relationships to the U.S., unless the
broker has documentary evidence in its records that the holder is a non-U.S.
holder and certain other conditions are met or the holder otherwise established
an exemption.

     Backup withholding is not an additional tax. Any amounts that we withhold
under the backup withholding rules will be refunded or credited against the
non-U.S. holder's U.S. federal income tax liability if certain required
information is furnished to the IRS.

     The U.S. Treasury Department has promulgated final regulations regarding
the withholding and information reporting rules discussed above. In general,
those regulations do not significantly alter the substantive withholding and
information reporting requirements but unify current certification procedures
and forms and clarify reliance standards. The final regulations are generally
effective for payments made after December 31, 2000, subject to transition
rules.

     The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares included in this offering are subject to
approval of certain legal matters by counsel and to certain other conditions.
The underwriters are obligated to purchase all the shares, other than those
covered by the over-allotment option described below, if they purchase any of
the shares.


     The underwriters, for whom Salomon Smith Barney Inc., Lehman Brothers Inc.,
Credit Suisse First Boston Corporation and Deutsche Bank Securities Inc. are
acting as representatives, propose to offer some of the shares directly to the
public at the public offering price set forth on the cover page of this
prospectus and some of the shares to selected dealers at the public offering
price less a concession not in excess of $     per share. The underwriters may
allow, and such dealers may reallow, a concession not in excess of $     per
share on sales to other dealers. If all of the shares are not sold at the
initial offering price, the representatives may change the public offering price
and the other selling terms. The representatives have advised Alamosa that the
underwriters do not intend to confirm any sales to any accounts over which they
exercise discretionary authority.


     We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus, to purchase up to 1,607,100 additional shares of
common stock at the public offering price less the underwriting discount. The
underwriters may exercise this option solely for the purpose of covering
over-allotments, if any, in connection with this offering. To the extent the
option is exercised, each underwriter will be obligated, subject to specified
conditions, to purchase a number of additional shares approximately
proportionate to that underwriter's initial purchase commitment.

     We, our officers and directors, and some of our other stockholders have
agreed that, for a period of 180 days from the date of this prospectus, we and
they will not, without the prior written consent of Salomon Smith Barney Inc.,
offer, sell, contract to sell, pledge, assign or otherwise dispose of or hedge
any shares of common stock of Alamosa or any securities convertible into or
exchangeable for common stock. Salomon Smith Barney Inc. in its sole discretion
may release any of the securities subject to these lock-up agreements at any
time without notice.

     As part of this sale of our common stock, the underwriters have agreed to
reserve a maximum of 10% of the shares of our common stock to be sold in this
offering for sale to our current stockholders at a price per share equal to the
public offering price less the underwriting discount. The underwriters will not
be entitled to any discount or commission on these shares and the proceeds to us
will be the same as if the shares were sold to the general public. However, the
number of shares of common stock available for sale to the general public will
be reduced to the extent of sales of shares to our current stockholders.


     At our request, 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 will be reduced to the
extent of sales of directed shares to any of the persons for whom they have been
reserved. Any shares not so purchased will be offered by the underwriters on the


                                       105
<PAGE>   110

same basis as all other shares of common stock offered hereby. We have agreed to
indemnify the underwriters against specified liabilities and expenses, including
liabilities under the Securities Act of 1933, in connection with the sales of
the directed shares.

     Prior to this offering, there has been no public market for our common
stock. Consequently, the initial public offering price for the shares was
determined by negotiations among us and the representatives. Among the factors
considered in determining the initial public offering price were our record of
operations, our current financial condition, our future prospects, our markets,
the economic conditions in and future prospects for the industry in which we
compete, our management, and currently prevailing general conditions in the
equity securities markets, including current market valuations of publicly
traded companies considered comparable to us. There can be no assurance,
however, that the prices at which the shares will sell in the public market
after this offering will not be lower than the price at which they are sold by
the underwriters or that an active trading market in the common stock will
develop and continue after this offering.

     We will apply to have the common stock included for quotation on the Nasdaq
National Market under the symbol "APCS."

     The following table shows the underwriting discounts and commissions to be
paid to the underwriters by us in connection with this offering. These amounts
are shown assuming both no exercise and full exercise of the underwriters'
option to purchase additional shares of common stock.

</TABLE>

     In connection with the offering, Salomon Smith Barney Inc., on behalf of
the underwriters, may purchase and sell shares of common stock in the open
market. These transactions may include over-allotment, syndicate covering
transactions and stabilizing transactions. Over-allotment involves syndicate
sales of common stock in excess of the number of shares to be purchased by the
underwriters in the offering, which creates a syndicate short position.
Syndicate covering transactions involve purchases of the common stock in the
open market after the distribution has been completed in order to cover
syndicate short positions. Stabilizing transactions consist of certain bids or
purchases of common stock made for the purpose of preventing or retarding a
decline in the market price of the common stock while the offering is in
progress.

     The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when
Salomon Smith Barney Inc., in covering syndicate short positions or making
stabilizing purchases, repurchases shares originally sold by that syndicate
member.

     Any of these activities may cause the price of the common stock to be
higher than the price that otherwise would exist in the open market in the
absence of such transactions. These transactions may be effected on the Nasdaq
National Market or in the over-the-counter market, or otherwise and, if
commenced, may be discontinued at any time.

     We estimate that the total expenses of this offering will be $     .


     The representatives may, from time to time, engage in transactions with and
perform services for us in the ordinary course of their business. In particular,
Salomon Smith Barney Inc., Credit Suisse First Boston Corporation and Lehman
Brothers Inc. are also acting as underwriters in the offering of our senior
discount notes.


     We have agreed to indemnify the underwriters against specified liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make in respect of any of those
liabilities.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Managers and
Members of Alamosa PCS LLC:

     In our opinion, the accompanying balance sheets and the related statements
of operations, members' equity and cash flows present fairly, in all material
respects, the financial position of Alamosa PCS LLC (a development stage
enterprise) at December 31, 1998 and September 30, 1999, and the results of its
operations and its cash flows for the period from July 16, 1998 (inception)
through December 31, 1998, the nine-month period ended September 30, 1999 and
the period from July 16, 1998 (inception) through September 30, 1999, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                         NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION AND BUSINESS OPERATIONS

     Alamosa PCS LLC, referred to in these financial statements as the Company
or 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 provide 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. As described in Note 11,
Alamosa has signed a letter of intent to amend its affiliation agreements with
Sprint PCS 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.

     As described in Note 11, Alamosa PCS Holdings Inc. was formed in October
1999 in anticipation of an initial public offering. Immediately prior to the
offering, shares of Alamosa PCS Holdings Inc., the registrant, will be exchanged
for the Company's membership interests. The Company will be wholly owned by
Alamosa PCS Holdings Inc.

     Alamosa is 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. of
$250 million and proceeds of the initial public offering described in Note 11.
From inception through September 30, 1999, the Company has commenced operations
in seven markets. Since inception, the Company has incurred revenues and
expenses of $2,000,060 and $20,612,301 resulting in a deficit accumulated during
the development stage of $18,612,241 at September 30, 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 will be the development of the Sprint PCS
subscriber base within that market.

     The Regulations of the Company, as amended, provide for the governance and
administration of the Company's business, allocation of profits and losses, tax
allocations, transactions with partners, disposition of ownership interest and
other matters. The Regulations establish two classes of membership interests.
Class I members have full voting rights and are entitled to full benefits of
ownership of their share of the Company. Class II members consist of additional
non-voting share interests of the Company which the Board of Managers may
authorize to be distributed to employees of the Company under an incentive bonus
plan.

     The Regulations generally provide 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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The following is a 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.

     As of September 30, 1999, other liabilities consist of a bank overdraft of
$244,369. This overdraft was mainly due to the timing of transfers between
Alamosa's operating and investment accounts.

  Inventory

     Inventory consists of handsets and related accessories. Inventories
purchased for resale will be carried at the lower of cost, determined using
weighted average, or market. Market will be determined using replacement cost in
accordance with industry standards.

  Microwave relocation

     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 insignificant in 1998 and totaled $39,295 for the
nine-month period ended September 30, 1999.

  Property, equipment, and construction in progress

     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.

                                ALAMOSA PCS LLC

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     Asset lives are as follows:

<TABLE>
<S>                                                        <C>
Buildings...............................................     20 years
Network equipment.......................................   5-10 years
Vehicles................................................      5 years
Furniture and office equipment..........................    5-7 years
</TABLE>

     Leasehold improvements are depreciated over the shorter of the remaining
term of the lease or the estimated useful life of the improvement.

     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. No interest was capitalized in 1998. Total interest capitalized is
$656,800 as of September 30, 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 $11,500 and $323,000 at December 31, 1998 and
September 30, 1999 are recorded in property and equipment. The Company amortized
computer software costs of approximately $800 and $12,200 during 1998 and for
the nine month period ended September 30, 1999.


  Start-up costs

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

     The Company has expensed start-up and organization costs as incurred. The
adoption of this statement will have no effect on the Company's financial
position or results of operations.

  Advertising costs

     Advertising costs are expensed as incurred. Advertising expenses totaled
approximately $2,100 and $2,282,000 during 1998 and for the nine-month period
ended September 30, 1999 respectively. Advertising costs include handset subsidy
expenses representing the excess of the cost of handsets over the retail sales
price. There was no handset subsidy expense during 1998. Handset subsidy expense
was approximately $1,194,000 for the nine-month period ended September 30, 1999.

  Income taxes

     At December 31, 1998 and September 30, 1999, Alamosa is organized as a
Texas limited liability company. Therefore, the results of operations of the
Company are included in the income tax returns of its members. Accordingly, no
provision for income taxes is recorded in the accompanying financial statements.

  Revenue recognition

     The Company will recognize revenue as services are performed. Sprint PCS
will handle Alamosa's billings and collections and will retain 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 will be recorded as an operating expense. 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.
                                       F-9
<PAGE>   121
                                ALAMOSA PCS LLC

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     Sprint PCS will pay 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 sales when incurred.


     Product revenues consisting of proceeds from sales of handsets and
accessories will be recorded net of an allowance for sales returns. The
allowance will be estimated based on Sprint PCS's handset return policy which
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 nine-month period ended September 30,
1999 product revenue was $818,678. The cost of these products was $1,991,963;
$797,633 of this cost has been classified as cost of products sold and
$1,194,000 of the cost which 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 No. 25,
"Accounting for Stock Issued to Employees" and related interpretations in
accounting for its employee stock options. Under APB 25, the Company recorded no
compensation expense related to stock options at December 31, 1998. At September
30, 1999, the Company recorded compensation expense of $6,822,037 which is
presented as equity participation compensation expense in the Company's
Statement of Operations. The equity participation compensation expense relates
to two employees whose normal compensation is recorded in selling, general and
administrative expenses. The Company has implemented the disclosure-only
provisions of 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.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  Effects of recent accounting pronouncements

     In June 1998 and June 1999, the Financial Accounting Standards Board,
commonly referred to as FASB, issued Statement of Financial Accounting
Standards, or 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.

     The American Institute of Certified Public Accountants issued Statement of
Position 98-5, "Reporting on the Costs of Start-Up Activities," in April 1998.
Effective for financial statements for fiscal years beginning after December 15,
1998, this statement requires costs of start-up activities and organization
costs to be expensed as incurred. Start-up activities are defined as those
one-time activities related to opening a new facility, introducing a new product
or service, conducting business in a new territory, conducting business with a
new class of customer or beneficiary, initiating a new process in an existing
facility, or commencing some new operation. The Company has not capitalized any
expenses with such characteristics for financial reporting purposes. Therefore,
the Company believes adoption of this statement will not materially impact the
financial statements.

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards 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. However, in the current year, no items represent
comprehensive income as defined in SFAS No. 130.

3. UNAUDITED PRO FORMA AND AS ADJUSTED INFORMATION

     The unaudited pro forma and as adjusted information reflects certain
assumptions regarding transactions and their effects that would occur as a
result of the initial public offering described in Note 11.

  Unaudited pro forma income information

     The unaudited pro forma information as shown on the statement of operations
is presented to show the effects of income taxes related to the Company's
anticipated 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
nine-month period ended September 30, 1999. Application of the provisions of
Statement of Financial Accounting Standards 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.

                                ALAMOSA PCS LLC

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  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 11.

  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 11. The
calculation was made in accordance with Statement of Financial Accounting
Standards No. 128, "Earnings Per Share." Diluted weighted average shares
outstanding at September 30, 1999 exclude 487,288 incremental potential common
shares from stock options because inclusion would have been antidilutive.

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.

7. RELATED PARTY TRANSACTIONS

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

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 $902,243 and $1,834,853 for these services during 1998
and for the nine-month period ended September 30, 1999 respectively. Engineering
fees under this agreement are recorded in construction in progress and property
and equipment and comprise approximately 72% and 3% of fixed asset purchases
during 1998 and 1999 respectively. At December 31, 1998 and September 30, 1999,
amounts payable under these agreements amounted to $443,610 and $737,753.

     Effective September 20, 1998, Alamosa entered into a special services

  Agreement with American Tower Corporation


     In August 1998, Alamosa entered into a master site development and lease
agreement with Specialty, now a subsidiary of American Tower Corporation.
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 becoming a subsidiary of American Tower Corporation, Specialty was
related to Alamosa through one of Alamosa's directors who owned interests in
both Alamosa and Specialty and was an employee and officer of Specialty and
Specialty's then parent company. 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 members. This individual is also a
stockholder of Specialty Teleconstructors, Inc. and acts as a vice president of
American Tower Corporation. No amounts were paid or outstanding under this
agreement during 1998. As of September 30, 1999, $165,300 had been 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, one 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, as well as a pro rata portion of real estate taxes on the property, and
subject to adjustment.

     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 Alamosa's directors and the general manager of
South Plains Advance Communications & Electronics, Inc. South Plains holds an
ownership interest in 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. As of September 30, 1999,
$27,501 had been paid under this lease.

     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, 1998 and September 30, 1999.

8. EMPLOYEE BENEFITS

     Effective November 13, 1998, the Company 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 31, 1998 and the nine-month period ended September 30, 1999.

     On October 2, 1998, the Company entered into an employee agreement with its
Chief Operating Officer. The agreement provides for the granting of stock
options in three series. The initial exercise price will be 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 will increase 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 will be exchanged for options 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.


     On October 14, 1998, the Board of Members approved an Incentive Ownership
Plan. The plan consists of 3,500 units comprised of 1200 Series 8, 1150 Series
15 and 1150 Series 25 units. The exercise price for each series is based on a
pre-defined strike price which increases by an annual rate of 8%, 15% or 25%
compounded monthly beginning July 1, 2000. The initial exercise prices are
$564.79, $623.84 and $711.88 for the Series 8, Series 15 and Series 25 options,
respectively. Each unit provides the holder an option to purchase an interest in
the Company. Vested units may be 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 will 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.


     The Company applies Accounting Principals Board Opinion No. 25, "Accounting
for Stock Issued to Employees" and related interpretations, in accounting for
its plans. Under opinion no. 25, no compensation expense or deferred
compensation was recorded as of December 31, 1998. As of September 30, 1999, the
Company has recorded unearned compensation of $11,193,751. This amount is being
amortized in accordance with FASB Interpretation No. 28 over the vesting periods
of the individual options. For the nine-month period ended September 30, 1999,
equity participation compensation expense of $6,822,037 has been recognized.
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" provides the Company the option of recognizing the cost of options
granted based on fair values of the options at the time of the grant. Due to the
floating exercise price of the options granted through September 30, 1999, the
accounting provisions of opinion no. 25 for variable plans have been followed.
The Company has subsequently amended the options outstanding at September 30,
1999 to establish a fixed exercise price creating a new measurement date.
Following this amendment, the provisions of opinion no. 25 for fixed plans will
be followed. The Company has decided not to elect the cost-recognition
provisions of SFAS No. 123.

     The fair value of each stock option is estimated at December 31, 1998 using
the Black-Scholes option pricing model: dividend yield of 0%; risk free interest
of 5.5%; expected lives of the options equal to 8.5 years; and a volatility rate
of 70%.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)


     Had the compensation expense for the options granted during 1998 been based
on the fair value pricing model described above, additional compensation expense
of $73,709 would have been recognized at December 31, 1998. This additional
compensation expense would have resulted in net loss of $997,531 and net loss
per share of $.02 at December 31, 1998. There would have been no additional
compensation expense for the nine-month period ended September 30, 1999. The
effects of applying SFAS No. 123 in this proforma disclosure are not indicative
of future amounts. The company anticipates making awards in the future under its
Incentive Ownership Plan.


9. 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 judgement and therefore, cannot be
determined with precision. Changes in assumptions could significantly affect
these estimates.

10. FINANCING AGREEMENTS

     On February 3, 1999, the Company issued a letter of credit for $7,500,000
in favor of Nortel. The letter of credit expired in June 1999.

     On June 10, 1999, the Company entered into a credit agreement with Nortel.
The proceeds are used to purchase equipment and to fund the construction of the
Company's portion of the Sprint PCS network. The financing terms permit Alamosa
to borrow $123 million through three commitment tranches through February 18,
2002, and will require minimum equipment purchases.

     The credit facility is collateralized by all of the Company's assets and
capital stock including future issues under the terms of the agreement. The
Company is required to maintain certain financial ratios and other financial
conditions including minimum levels of revenue and wireless subscribers. In
addition, the Company is required to maintain a $1,000,000 cash balance as
security against the facility. This balance is recorded as a noncurrent asset.

                                ALAMOSA PCS LLC

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     In connection with the credit agreement with Nortel, each of the members
pledged its ownership interest in Alamosa to Nortel to collateralize the
Company's obligations under the credit agreement. The members were required to
secure 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 11. 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 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 3.5%. This interest
rate was 9.4% at September 30, 1999. In addition, an annual unused facility fee
of 0.75% will be charged beginning six months after the closing date. 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 end of the interest period, not to exceed three
months, in the case of Eurodollar loans. Interest expense for the period ended
September 30, 1999 totaled $544,055. 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, equal to 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.

     At September 30, 1999, the Company borrowed $59,678,288 against this
facility.

     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 substantially all of Alamosa's assets, including the affiliation
agreements to Nortel. 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 assignment with Nortel.

     The Company incurred approximately $4,074,000 of costs associated with
obtaining the Nortel financing. These costs consist of a loan origination fee
and debt issue costs which have been capitalized and are being amortized to
interest expense using the effective interest method over the term of the credit
facility.

11. OTHER SUBSEQUENT EVENTS

     In October 1999, the Company entered into a letter of intent to amend the
affiliation agreement with Sprint PCS to expand its service networks to include
markets located in Wisconsin. As a result, Alamosa formed its 99% owned
subsidiary, Alamosa Wisconsin LP, to perform Alamosa's obligations under the
affiliation agreements with Sprint PCS.

     The Company intends to file a registration statement for equity financing
through an initial public offering. Immediately prior to the closing of initial
public offering, the Company will reorganize the business into a holding company
structure. In connection with the reorganization, the members of Alamosa PCS,
LLC will receive 48,500,000 shares of common stock of Alamosa PCS Holdings, Inc.
in exchange for their membership interests in the limited liability company. The
ownership percentages among the Company's shareholders following the
reorganization will remain consistent with the ownership percentages described
in Note 1. The Company plans to utilize the proceeds from the aforementioned
offerings to fund the build-out of its expanded network.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     In addition to the initial public offering described above, the Company
expects to offer senior discount notes through a public offering. The senior
discount notes will be unsecured obligations and will rank equally with all
future senior debt and senior to all future subordinated debt. The senior
discount 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 Alamosa PCS Holdings, Inc. Therefore,
financial statements of guarantor subsidiaries have been omitted.

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

     The senior discount notes will be issued at a discount to their principal
amount and will 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 will contain
covenants limiting Alamosa PCS Holding, Inc.'s ability and the ability of its
subsidiaries to:

     - incur additional debt or issue preferred stock;

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

     - create liens on assets;

     - merge, consolidate or dispose of assets;

     - enter into transactions with affiliates; and

     - change lines of business.

     Holders of the senior discount notes will have the right to require Alamosa
PCS Holdings, Inc. 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 Alamosa and the occurrence of
any event of default pursuant to the affiliation agreements with Sprint PCS.


     In October 1999, the Company entered into a commitment letter to amend its
Nortel financing which increased the facility from $123 million to $250 million
and increased the Company's commitment to purchase equipment from Nortel. As of
December 31, 1999, Alamosa had remaining commitments of $117.6 million to
purchase equipment and infrastructure under the amended agreement. As
consideration for the amendment, the Company is required to issue to Nortel
warrants for 2% of the total equity as of the closing of the initial public
offering, on a fully diluted basis. The warrants will be issued and will be
exercisable by Nortel on the second anniversary of the closing date, unless
among other options, Alamosa raises an additional $75.0 million of capital and
uses the proceeds to prepay any loans under the Nortel facility prior to that
date. The exercise price for the warrants will be the price paid for the common
stock in the initial public offering. Subsequent to the closing of the amended
Nortel agreement, the interest rates charged by Nortel will increase on the base
rate loans from prime plus 2.5% to prime plus 2.75% and on the Eurodollar loans
from LIBOR plus 3.5% to LIBOR plus 3.75%. In addition, subsequent to the closing
of the amended Nortel agreement, Alamosa will no longer be required to pay a
premium on any equipment and services financed by Nortel.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)


     Effective October 1, 1999, Alamosa entered into a three-year employment
agreement with David Sharbutt, Alamosa's chairman, who was named Chief Executive
Officer. In addition, Alamosa granted options to Mr. Sharbutt to acquire 242,500
common shares at an exercise price of $1.15 per share which vest immediately
upon completion of the initial public offering and 1,455,000 shares at an
exercise price equal to the initial public offering price which vest 25% per
year beginning September 1, 2000. The options expire December 9, 2009. Based on
the expected offering price, the Company will recognize compensation expense of
$3,358,625 related to the 242,500 options issued with an exercise price below
the initial public offering price over the options vesting period.



     In October 1999, Alamosa amended the Chief Operating Officer's options,
described in Note 8, such that each of his three series of original options to
purchase 242,500 shares of common stock at exercise prices which increased by an
annual rate of 8%, 15% and 25%, compounded monthly beginning at the date of
grant, and that vested over three years will be exchanged for 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 vests
immediately upon 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 1,
2000. The expiration date of all of the Chief Operating Officer's options was
extended from January 5, 2008 to December 9, 2000. These amendments will result
in a new measurement date, and compensation expense of $973,682 will be
recognized upon completion of the initial public offering. The remaining
unearned compensation totaling $1,947,363 will be recognized over the amended
vesting period.



     In addition, in October 1999, Alamosa amended the Chief Technology
Officer's options, described in Note 8, such that his original options with
exercise prices which increased by an annual rate of 8%, 15%, or 25% (compounded
monthly beginning July 1, 2000) will be 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.
In addition, the three-year vesting period will be amended such that one-third
of each option series will be fully vested and exercisable upon completion of
the initial public offering, and another one-third of each series will vest on
each of October 29, 2000 and October 29, 2001. These amendments will result in a
new measurement date and recognition of compensation expense of $197,741 at the
completion of the initial public offering. The remaining unearned compensation
totaling $395,482 will be recognized over the amended vesting period.



     Effective December 1, 1999, the Company entered into an employment
agreement with its Chief Financial Officer, Kendall W. Cowan, which has a
five-year term and includes options to purchase 1,455,000 shares at the initial
public offering price and that will expire December 9, 2009. There is no
compensation cost related to these options.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS

     The Certificate of Incorporation of Alamosa PCS Holdings, Inc. ("Alamosa")
provides that the liability of the directors of Alamosa to Alamosa or any of its
stockholders for monetary damages arising from acts or omissions occurring in
their capacity as directors shall be limited to the fullest extent permitted by
the laws of Delaware or any other applicable law. This limitation does not apply
with respect to any action in which a director would be liable under Section 174
of the General Corporation Law of the State of Delaware nor does it apply with
respect to any liability in which a director:

     - breached his duty of loyalty to Alamosa or its stockholders;

     - did not act in good faith or, in failing to act, did not act in good
       faith;

     - acted in a manner involving intentional misconduct or a knowing violation
       of law or, in failing to act, shall have acted in a manner involving
       intentional misconduct or a knowing violation of law; or

     - derived an improper personal benefit.

     Alamosa's Certificate of Incorporation provides that Alamosa shall
indemnify its directors, officers and employees and former directors, officers
and employees to the fullest extent permitted by the laws of Delaware or any
other applicable law. Pursuant to the provisions of Section 145 of the General
Corporation Law of the State of Delaware, Alamosa has the power to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action, suit, or proceeding (other than an
action by or in the right of Alamosa) by reason of the fact that he is or was a
director, officer, employee, or agent of Alamosa, against any and all expenses,
judgments, fines and amounts paid in settlement actually and reasonably incurred
in connection with such action, suit, or proceeding. The power to indemnify
applies only if such person acted in good faith and in a manner he reasonably
believed to be in the best interest, or not opposed to the best interest, of
Alamosa and with respect to any criminal action or proceeding, had no reasonable
cause to believe his conduct was unlawful.

     The power to indemnify applies to actions brought by or in the right of
Alamosa as well, but only to the extent of defense and settlement expenses and
not to any satisfaction of a judgment or settlement of the claim itself and with
the further limitation that in such actions no indemnification shall be made in
the event of any adjudication of negligence or misconduct unless the court, in
its discretion, believes that in light of all the circumstances indemnification
should apply.

                                      II-1
<PAGE>   135

     The statute further specifically provides that the indemnification
authorized thereby shall not be deemed exclusive of any other rights to which
any such officer or director may be entitled under any bylaws, agreements, vote
of stockholders or disinterested directors, or otherwise.

     Reference is made to the Form of Underwriting Agreement, to be filed as
Exhibit 1.1 to this registration statement, which provides for indemnification
by the Underwriters under certain circumstances of the directors and officers of
Alamosa signing the registration statement and certain controlling persons of
Alamosa against certain liabilities, including those arising under the
Securities Act.

     Alamosa has directors' and officers' liability insurance covering its
directors and officers.

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


ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES



     Alamosa PCS Holdings, Inc., a Delaware corporation ("Alamosa") was formed
on October 19, 1999. It has no assets and has issued no capital stock.
Immediately prior to the closing of this initial public offering, we will
reorganize as described in the prospectus. In connection with the
reorganization, Alamosa will merge with Alamosa PCS Holdings, Inc., a Texas
corporation ("Texas Holdings"). To effectuate the merger, Alamosa will issue 100
shares of common stock to Texas Holdings. Alamosa will then merge into Texas
Holdings, with Alamosa as the surviving corporation. In the merger, Alamosa will
issue unregistered shares of Alamosa common stock to the stockholders of Texas
Holdings.



     Alamosa will also grant stock options to directors, officers, employees and
consultants before the closing of this initial public offering. These are the
only unregistered issuances of securities that Alamosa currently contemplates.



     Texas Holdings will be the successor to the current operating company,
Alamosa PCS, LLC, by virtue of a conversion of the LLC to a corporation.



     The persons to receive Alamosa common stock in connection with the
reorganization, their owners, the consideration to be received by Alamosa 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.

(3) The consideration for these stock options is an option to purchase a 0.3%

     None of the foregoing transactions will involve any public offering, and
issuances of securities in connection with such transactions will be made
pursuant to valid exemptions under the Securities Act of 1933 (the "Act"). The
following are the exemptions relied on for each issuance of securities pursuant
to our reorganization.



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



     Second, our issuance of 48,500,000 shares to the twenty-nine stockholders
of Texas Holdings, pursuant to the merger of Texas Holdings with and into
Alamosa, is exempt under Section 4(2). The merger will take place through direct
communication with the offerees, with no general solicitation or advertising.
Since Alamosa will be a subsidiary of Texas Holdings, these offerees will have a
pre-existing and substantial relationship with us.

The 6,173,500 shares is under the maximum of 15% of 48,500,000, or 7,275,000
provided in Rule 701(d)(2).


ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

     (a) Exhibits:

     The exhibits are as set forth in the Exhibit Index.

     (b) Financial Statement Schedules:

          No financial statement schedules are filed because the required
     information is not applicable or is included in the consolidated financial
     statements or related notes.

ITEM 17. UNDERTAKINGS

     The undersigned registrant hereby undertakes that:

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

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

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

     The undersigned registrant hereby undertakes to provide to the Underwriters
at the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

         ARTICLE 4.  Description and Authorization of Stock.

                  (a) Stock Authorization. The aggregate number of shares of
capital stock that the Corporation shall have the authority to issue is
100,000,000 shares, which shall consist of (i) 95,000,000 shares of Common
Stock, par value $0.01 per share (the "Common Stock") and (ii) 5,000,000 shares
of Preferred Stock, $0.01 par value per share (the "Preferred Stock").

                  (b) Common Stock.

                      (i) Voting Rights. The holders of Common Stock will be
entitled to one vote per share on all matters to be voted on by the stockholders
of the Corporation, including the election of directors. The holders of Common
Stock shall not have cumulative voting rights.

                      (ii) Dividends. Subject to the prior rights of any
Preferred Stock issued by the Corporation, as and if dividends are declared
thereon by the Board of Directors of the Corporation out of funds legally
available therefor, whether payable in cash, property or securities of the
Corporation, the holders of Common Stock will be entitled to share equally, on a
share-for-share basis, in all such dividends.

                      (iii) Liquidation. Upon any liquidation, dissolution or
winding up of the Corporation, after all amounts due and owing to the holders of

fully provided for, the holders of Common Stock shall be entitled to receive all
of the remaining assets of the Corporation available for distribution to holders
of Common Stock and will be entitled to share equally, on a share-for-share
basis, in such distribution. Neither the merger or consolidation of the
Corporation with or into another corporation or corporations, nor the sale or
transfer by the Corporation of all or part of its assets, nor the reduction of
its capital stock, will be deemed to be a liquidation, dissolution or winding up
of the Corporation within the meaning of this paragraph.

                  (c) Preferred Stock.

                      (i) Issuance. The Board of Directors is authorized,
subject to any limitations prescribed by law, to provide for the issuance of the
shares of Preferred Stock in series, and by filing a certificate pursuant to the
applicable law of the State of Delaware, to establish from time to time the
number of shares to be included in each such series, and to fix the designation,
powers, preferences, and rights of the shares of each such series and any
qualifications, limitations or restrictions thereof.

                          (A) The number of authorized shares of Preferred
Stock may be increased or decreased (but not below the number of shares thereof
then outstanding) by the affirmative vote of the holders of a majority of the
Common Stock, without a vote of the holders of the Preferred Stock, or of any
series thereof, unless a vote of any such holders is required pursuant to the
certificate or certificates establishing the series of Preferred Stock.

                           (B) Except as otherwise required by law, holders of
Common Stock, as such, shall not be entitled to vote on any amendment to this
Amended and Restated Certificate of Incorporation (including a certificate
establishing a series of Preferred Stock) that alters or changes the powers,
preferences, rights or other terms of one or more outstanding series of
Preferred Stock if the holders of such affected series are entitled to vote,
either separately or together with the holders of one or more other such series,
on such amendment pursuant to this Amended and Restated Certificate of
Incorporation (including a certificate establishing a series of Preferred Stock)
or pursuant to the DGCL.

                  (ii) Increases and Decreases in Series. The Board of Directors
of the Corporation may increase the number of shares (but not above the total
number of authorized shares of the class) of the Preferred Stock designated for
any existing series by a resolution adding to such series authorized and
unissued shares of the Preferred Stock not designated for any other series. The
Board of Directors of the Corporation may decrease the number of shares of the
Preferred Stock (but not below the number of shares thereof then outstanding)
designated for any existing series by a resolution, subtracting from such series
unissued shares of the Preferred Stock designated for such series, and the
shares so subtracted shall become authorized, unissued, and undesignated shares
of the Preferred Stock.

         ARTICLE 5. Rights of Stockholders. No holder of shares of stock of the
Corporation shall have any preemptive or other similar right, except as such
rights are expressly provided by contract, or by resolution creating a series of
Preferred Stock, to purchase or subscribe for or receive any shares of any
class, or series thereof, of stock of the Corporation, whether now or hereafter
authorized, or any warrants, options, bonds, debentures or other securities
convertible into, exchangeable for or carrying any right to purchase any shares
of any class of stock, or series thereof; but such additional shares of stock
and such warrants, options, bonds, debentures or other securities convertible
into, exchangeable for or carrying any right to purchase any shares of any class
of stock, or series thereof, may be issued or disposed of by the Board of
Directors to such persons, and on such terms and for such lawful consideration,
as in its discretion it shall deem advisable or as to which the Corporation
shall have by binding contract agreed.

         ARTICLE 6. Meetings of Stockholders.

                  Effective immediately following the consummation of the
initial public offering of the Corporation's Common Stock pursuant to a
registration statement declared effective under the Securities Act of 1933, as
amended and including any successor provisions thereto (the "1933 Act"), any
action required or permitted to be taken by the stockholders of the Corporation
must be effected at a duly called annual or special meeting of stockholders of
the Corporation and may not be effected by any consent in writing by such
stockholders. Special meetings of stockholders of the Corporation may be called
only by the Chairman of the Board, if there is one, by the President, by the
Board of Directors pursuant to a resolution adopted by a majority of the total
number of authorized directors (whether or not there exist any vacancies in
previously authorized directorships at the time such resolution is presented to
the Board of Directors for adoption), or by holders of not less than a

                                        3

<PAGE>   4




majority of the voting power of the Voting Stock (as defined in ARTICLE 13 (Fair
Price)) that would be entitled to vote at such meeting.

         ARTICLE 7. Duration of Existence. The Corporation is to have perpetual
existence.

         ARTICLE 8. Amendments to the Bylaws. In furtherance of, and not in
limitation of, the powers conferred by statute, the Board of Directors is
expressly authorized to adopt, amend or repeal the Bylaws of the Corporation or
adopt new Bylaws, without any action on the part of the stockholders; provided,
however, adoption, amendment or repeal of the Bylaws in a manner that would make
them inconsistent with ARTICLE 4(c) (Description and Authorization of Stock --
Preferred Stock), ARTICLE 6 (Meetings of Stockholders), this ARTICLE 8
(Amendments to the Bylaws), ARTICLE 9 (Board of Directors), ARTICLE 10
(Amendments to the Certificate) or ARTICLE 13 (Fair Price), shall be made only
by the affirmative vote of the holders of at least 80% of the voting power of
the Voting Stock, voting together as a single class. In the event that any term
or provision of the Bylaws is inconsistent, or conflicts, with the terms or
provisions of this Amended and Restated Certificate of Incorporation, this
Amended and Restated Certificate of Incorporation shall control.

         ARTICLE 9. Board of Directors.

                  (a) Number. Except as otherwise fixed by the provisions of a
resolution adopted pursuant to ARTICLE 4(c) (Description and Authorization of
Stock -- Preferred Stock) relating to the rights of the holders of the Preferred
Stock to elect additional directors under specified circumstances, the number of
directors which shall constitute the whole Board of Directors shall be not less
than three and shall be fixed from time to time exclusively by the Board of
Directors pursuant to a resolution adopted by a majority of the total number of
authorized directors (whether or not there exist any vacancies in the previously
authorized directorships at the time any such resolution is presented to the
Board of Directors for adoption).

                  (b) Staggered Board of Directors. At the Meeting of
Stockholders (or consent in lieu thereof) at which this Amended and Restated
Certificate of Incorporation is adopted or ratified, the directors shall be
divided into three classes, designated Class I, Class II and Class III (which at
all times shall be as nearly equal in number as possible), with the term of
office of Class I directors to expire at the 2001 Annual Meeting of
Stockholders, the term of office of Class II directors to expire at the 2002
Annual Meeting of Stockholders, and the term of office of Class III directors to
expire at the 2003 Annual Meeting of Stockholders, upon election and
qualification of their successors. At each annual meeting of stockholders
following such initial classification and election, directors elected to succeed
those directors whose terms expire shall be elected for a term of office to
expire at the third succeeding annual meeting of stockholders after their
election, upon election and qualification of their successors.

                  (c) Removal of Directors. Subject to the right of the holders
of any class or series of Preferred Stock then outstanding, any director, or the
entire Board of Directors, may be removed from office at any time, but only for
cause and only by the affirmative vote of the holders of at least

                                        4

<PAGE>   5




80% of the voting power of the Voting Stock, voting together as a single class.
Except as may otherwise be provided by law, cause for removal shall exist only
if the director whose removal is proposed:

                           (i) has been convicted of a felony by a court of
competent jurisdiction and such conviction is no longer subject to direct
appeal;

                           (ii) has been adjudged by a court of competent
jurisdiction to be liable for gross negligence or misconduct in the performance
of such director's duties to the Corporation in a matter of substantial
importance to the Corporation, and such adjudication has become final and
non-appealable; or

                           (iii) has missed six consecutive meetings of the
Board of Directors.

                  (d) Vacancies. Subject to the rights of the holders of any
class or series of Preferred Stock then outstanding, newly created directorships
resulting from any increase in the authorized number of directors or any
vacancies of the Board of Directors resulting from death, resignation,
retirement, disqualification, removal from office or other reason shall be
solely filled by a majority vote of the directors then in office, though less
than a quorum, or by a sole remaining director. Directors so chosen shall hold
office for a term expiring at the annual meeting of stockholders at which the
term of office of the class to which they have been elected expires, upon
election and qualification of their successors. No decrease in the number of
authorized directors constituting the entire Board of Directors shall shorten
the term of any incumbent director. Under no circumstances shall the
Corporation's stockholders fill any newly created directorships.

                  (e) Ballots, Cumulative Voting. Election of directors need not
be by written ballot unless the Bylaws shall so provide. No holders of shares of
capital stock of the Corporation shall have any rights to cumulate votes in the
election of directors.

                  (f) Preferred Stock, Directors. Notwithstanding the foregoing,
whenever the holders of Preferred Stock shall have the right to elect directors
at an annual or special meeting of stockholders, the election, term of office,
filling of vacancies, and other features of such directorships shall be governed
by the terms of any resolution adopted pursuant to ARTICLE 4 (Description and
Authorization of Stock) of this Amended and Restated Certificate of
Incorporation applicable thereto, and such directors so elected shall not be
divided into classes pursuant to this ARTICLE 9 (Board of Directors) unless
expressly provided by such terms.

         ARTICLE 10. Amendments to the Certificate. The Corporation shall have
the right, subject to any express provisions or restrictions contained in this
Amended and Restated Certificate of Incorporation of the Corporation, from time
to time, to amend this Amended and Restated Certificate of Incorporation or any
provision thereof in any manner now or hereafter provided by law.
Notwithstanding the foregoing or any other provisions of this Amended and
Restated Certificate of Incorporation or any provision of law which might
otherwise permit a lesser vote or no vote, but in addition to any vote required
by law or this Amended and Restated Certificate of Incorporation, the


                                        5

<PAGE>   6




affirmative vote of the holders of at least 80% of the voting power of the
Voting Stock, voting together as a single class, shall be required to adopt any
provision inconsistent with, or to amend or repeal ARTICLE 4(c) (Description and
Authorization of Stock -- Preferred Stock), ARTICLE 6 (Meetings of
Stockholders), ARTICLE 8 (Amendments to the Bylaws), ARTICLE 9 (Board of
Directors), this ARTICLE 10 (Amendments to the Certificate) or ARTICLE 13 (Fair
Price). The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Amended and Restated Certificate of Incorporation,
and all rights conferred upon stockholders herein are granted subject to this
reservation.

         ARTICLE 11. Indemnification.

                  (a) The Corporation shall indemnify any person who was, is or
is threatened to be made a party to a proceeding (as hereinafter defined) by
reason of the fact that he or she (i) is or was a director or officer of the
Corporation or (ii) while a director or officer of the Corporation, is or was
serving at the request of the Corporation as a director, officer, partner,
venturer, proprietor, trustee, employee, agent or similar functionary of any
foreign or domestic corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan, or other enterprise, to the
fullest extent permitted under the DGCL, as the same exists or may hereafter be
amended. Notwithstanding the foregoing, except as provided in (c) below, the
Corporation shall indemnify any such person in connection with a proceeding (or
part thereof) initiated by such person only if such proceeding (or part thereof)
was authorized by the Board of Directors of the Corporation.

                  (b) Such rights shall be contract rights and as such shall run
to the benefit of any director or officer who is elected and accepts the
position of the director or officer of the Corporation or elects to continue to
serve as a director or officer of the Corporation while this ARTICLE 11
(Indemnification) is in effect. Any repeal or amendment of this ARTICLE 11
(Indemnification) shall be prospective only and shall not limit the rights of
any such director or officer or the obligations of the Corporation with respect
to any claim arising from or related to the services of such director or officer
in any of the foregoing capacities prior to any such repeal or amendment to this
ARTICLE 11 (Indemnification). Such right shall include the right to be paid by
the Corporation expenses incurred in defending any such proceeding in advance of
its final disposition to the maximum extent permitted under the DGCL.

                  (c) If a claim for indemnification or advancement of expenses
hereunder is not paid in full by the Corporation within 60 days after a written
claim has been received by the Corporation, the claimant may at any time
thereafter bring suit against the Corporation to recover the unpaid amount of
the claim, and if successful in whole or in part, the claimant shall also be
entitled to be paid the expenses of prosecuting such claim. It shall be a
defense to any such action that such indemnification or advancement of costs of
defense are not permitted under the DGCL, but the burden of proving such defense
shall be on the Corporation. Neither the failure of the Corporation (including
the Board of Directors or any Committee thereof, independent legal counsel, or
stockholders) to have made its determination prior to the commencement of such
action that indemnification of, or advancement of costs of defense to, the
claimant, is permissible in the circumstances nor an actual determination by the
Corporation (including the Board of Directors or


                                        6

<PAGE>   7




any Committee thereof, independent legal counsel, or stockholders) that such
indemnification or advancement is not permissible shall be a defense to the
action or create a presumption that such indemnification by the Corporation is
not permissible.

                  (d) In the event of the death of any person having rights of
indemnification under the foregoing provisions, such rights shall inure to the
benefit of his or her heirs, executors, administrators, and personal
representatives. The rights conferred above shall not be exclusive of any other
right which any person may have or hereafter acquire under any statute, bylaw,
resolution of stockholders or directors, agreement or otherwise. The Corporation
may additionally indemnify any employee or agent of the Corporation to the
fullest extent permitted by law.

                  (e) As used herein, the term "proceeding" means any threatened
pending, or completed action, suit, or proceeding, whether civil, criminal,
administrative, arbitrative, or investigative, any appeal in such an action,
suit, or proceeding, and any inquiry or investigation that could lead to such an
action, suit, or proceeding.

         ARTICLE 12. Limitation on Liability. No director of the Corporation
shall be liable to the Corporation or its stockholders for monetary damages for
breach of fiduciary duty as a director, except for liability (i) for any breach
of the director's duty of loyalty to the Corporation or its stockholders, (ii)
for acts or omissions not in good faith or that involve intentional misconduct
or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for
any transaction from which the director derived an improper personal benefit. If
the DGCL hereafter is amended to authorize the further elimination or limitation
of the liability of directors, then the liability of a director of the
Corporation, in addition to the limitation on personal liability provided
herein, shall be limited to the fullest extent permitted by the amended DGCL.
Any repeal or modification of this ARTICLE 12 (Limitation on Liability) by the
stockholders of the Corporation shall be prospective only and shall not
adversely affect any limitation of the personal liability of a director of the
Corporation existing at the time of such repeal or modification.

         ARTICLE 13. Fair Price.

                  (a) Special Vote Required For Certain Business Combinations.
In addition to any affirmative vote required by law or this Amended and Restated
Certificate of Incorporation or the Bylaws of the Corporation, and except as
otherwise expressly provided in Section (b) of this ARTICLE 13 (Fair Price --
When Special Vote Not Required), a Business Combination (as hereinafter defined)
with, or proposed by or on behalf of any Interested Stockholder (as hereinafter
defined) or any Affiliate or Associate (as hereinafter defined) of any
Interested Stockholder or any person who after such Business Combination would
be an Affiliate or Associate of such Interested Stockholder shall require the
affirmative vote of the holders of not less than 80% of the voting power of the
Voting Stock, voting together as a single class. Such affirmative vote shall be
required notwithstanding the fact that no vote may be required, or that a lesser
percentage or separate class vote may be specified, by law, by any other
provision of this Amended and Restated Certificate of Incorporation or the
Bylaws of the Corporation, by any agreement with any national securities
exchange or otherwise.

<PAGE>   8




                  (b) When Special Vote Not Required. The provisions of Section
(a) of this ARTICLE 13 (Fair Price -- Special Vote Required for Certain Business
Combinations) shall not be applicable to any particular Business Combination,
and such Business Combination shall require only such affirmative vote, if any,
as is required by law, by any other provision of this Amended and Restated
Certificate of Incorporation or the Bylaws of the Corporation, by any agreement
with any national securities exchange or otherwise if, in the case of a Business
Combination involving the receipt of consideration by the holders of the
Corporation's outstanding Capital Stock (as hereinafter defined), the condition
specified in paragraph (i) below is met or all of the conditions specified in
paragraph (ii) below are met or if, in the case of a Business Combination not
involving the receipt of consideration by the holders of the Corporation's
outstanding Capital Stock, the condition specified in paragraph (i) below is
met:

                           (i) Approval by Disinterested Directors. The Business
Combination (either specifically or as a transaction which is within an approved
category of transactions) shall have been approved by a majority of the
Disinterested Directors (as hereinafter defined) prior to the stockholder
becoming an Interested Stockholder, it being understood that this condition
shall not be capable of satisfaction unless there are at least three
Disinterested Directors.

                           (ii) Minimum Price, Form of Consideration and Other
Requirements. All of the following conditions shall have been met:

                                (A) Minimum Price Requirements. With respect
to every class or series of outstanding Capital Stock of the Corporation,
whether or not the Interested Stockholder has previously acquired beneficial
ownership of any shares of such class or series of Capital Stock:

                                    (1) The aggregate amount of cash
plus the Fair Market Value (as hereinafter defined), as of the date of the
consummation of the Business Combination, of consideration other than cash to be
received per share by holders of Common Stock in such Business Combination shall
be at least equal to the higher of the amounts determined pursuant to clauses
(aa) and (bb) below:

                                        (aa) the highest per-share price
(including any brokerage commissions, transfer taxes and soliciting dealers'
fees) paid by or on behalf of the Interested Stockholder for any share of Common
Stock in connection with the acquisition by the Interested Stockholder of
beneficial ownership of shares of Common Stock (x) within the two-year period
immediately prior to the Announcement Date (as hereinafter defined) or (y) in
the transaction or series of related transactions in which it became an
Interested Stockholder, whichever is higher, in either case as adjusted for any
subsequent stock split, stock dividend, subdivision or reclassification with
respect to Common Stock; and

                                        (bb) the Fair Market Value per share of
Common Stock (x) on the Announcement Date or (y) on the Determination Date (as

<PAGE>   9




                              (2) The aggregate amount of cash plus the Fair
Market Value, as of the date of the consummation of the Business Combination, of
consideration other than cash to be received per share by holders of shares of
any class or series of outstanding Capital Stock, other than Common, shall be at
least equal to the highest of the amounts determined pursuant to clauses (aa),
(bb) and (cc) below:

                                  (aa) the highest per-share price (including
any brokerage commissions, transfer taxes and soliciting dealers' fees) paid by
or on behalf of the Interested Stockholder for any share of such class or series
of Capital Stock in connection with the acquisition by the Interested
Stockholder of beneficial ownership of shares of such class or series of Capital
Stock (x) within the two-year period immediately prior to the Announcement Date
or (y) in the transaction or series of related transactions in which it became
an Interested Stockholder, whichever is higher, in either case as adjusted for
any subsequent stock split, stock dividend, subdivision or reclassification with
respect to such class or series of Capital Stock;

                                  (bb) the Fair Market Value per share of such
class or series of Capital Stock (x) on the Announcement Date or (y) on the
Determination Date, whichever is higher, as adjusted for any subsequent stock
split, stock dividend, subdivision or reclassification with respect to such
class or series of Capital Stock; and

                                  (cc) the highest preferential amount per
share, if any, to which the holders of shares of such class or series of Capital
Stock would be entitled to in the event of any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Corporation
regardless of whether the Business Combination to be consummated constitutes
such an event.

                           (B) Form of Consideration and Other Requirements.


                               (1) The consideration to be received by holders
of a particular class or series of outstanding Capital Stock shall be in cash or
in the same form as previously has been paid by or on behalf of the Interested
Stockholder in connection with its direct or indirect acquisition of beneficial
ownership of shares of such class or series of Capital Stock. If the
consideration so paid for shares of any class or series of Capital Stock varies
as to form, the form of consideration of such class or series of Capital Stock
shall be in cash or the form paid by or on behalf of the Interested Stockholder
in connection with its direct or indirect acquisition of beneficial ownership of
the largest number of shares of such class or series of Capital Stock.

                               (2) After the Determination Date and prior to the
consummation of such Business Combination:

                                   (aa) there shall have been no failure to
declare and pay at the regular date therefor any full regular dividends (whether
or not cumulative) payable in accordance with the terms of any outstanding
Capital Stock, other than the Common Stock, except as approved by a majority of
the Disinterested Directors;


                                        9

<PAGE>   10




                                   (bb) there shall have been no reduction in
the amount, or change in the frequency of payment, of any dividends regularly
paid on the Common Stock (except as necessary to reflect any stock split, stock
dividend, subdivision or reclassification of the Common Stock), except as
approved by a majority of the Disinterested Directors; and

                                   (cc) there shall have been an increase in the
amount of any dividends regularly paid on the Common Stock as necessary to
reflect any reverse stock split or reclassification of the Common Stock, or any
split, recapitalization, reorganization or any similar transaction that has the
effect of reducing the number of outstanding shares of Common Stock, unless the
failure so to increase the amount of such dividends is approved by a majority of
the Disinterested Directors.

                               (3) such Interested Stockholder shall not have
become the beneficial owner of any additional shares of Capital Stock except as
part of or otherwise in connection with the transaction or series of related
transactions that resulted in such Interested Stockholder becoming an Interested
Stockholder.

                               (4) After the Determination Date and prior to the
consummation of such Business Combination, such Interested Stockholder shall not
have received the benefit, directly or indirectly (except proportionately as a
stockholder of the Corporation), of any loans, advances, guarantees, pledges or
other financial assistance or any tax credits or other tax advantages provided
by the Corporation, whether in anticipation of or in connection with such
Business Combinations or otherwise.

                               (5) After the Determination Date and prior to the
consummation of such Business Combination, such Interested Stockholder shall not
have made any major change in the Corporation's business or capital structure
without the approval of a majority of the Disinterested Directors.

                               (6) A proxy or information statement describing
the proposed Business Combination and complying with the requirements of the
1934 Act shall be mailed to all stockholders of the Corporation at least 30 days
prior to the consummation of such Business Combination (whether or not such
proxy or information statement is required to be mailed pursuant to the 1934
Act). Such proxy or information statement shall contain, in a prominent place,
any statement as to the advisability (or inadvisability) of the Business
Combination that the Disinterested Directors, or any of them, may choose to make
and, if deemed advisable by a majority of the Disinterested Directors, the
opinion of an investment banking firm selected by a majority of the
Disinterested Directors as to the fairness (or not) of the terms of the Business
Combination from a financial point of view to the holders of the outstanding
shares of Capital Stock other than the Interested stockholder and its Affiliates
or Associates, such investment banking firm to be paid a reasonable fee for its
services by the Corporation.

                  (c) Certain Definitions. The following definitions shall apply
with respect to this ARTICLE 13 (Fair Price):

                           (iv) The term "Interested Stockholder" shall mean any
person (other than the Corporation or any Subsidiary and other than any
profit-sharing, employee stock ownership or other employee benefit plan of the
Corporation or any Subsidiary or any trustee of or fiduciary with respect to any
such plan when acting in such capacity) who or which:

                                (A) is the beneficial owner, directly or
indirectly, of Voting Stock representing 20% or more of the voting power of all

that if any of Rosewood Telecommunications, L.L.C., South Plains Advanced

Telecommunications, Inc., Tregan International Corp., Plateau
Telecommunications, Incorporated, XIT Telecommunication & Technology, Inc., LEC
Development, Inc., Wes-Tex Telecommunications, Inc., Longmont PCS, L.L.C. and
Yellow Rock PCS, LP is a party to an agreement that governs the voting of shares
of Common Stock, which agreement (x) has been approved by the Board of Directors
prior to the time it was entered into by such parties, (y) does not govern the
voting of Common Stock with respect to matters other than the election of
members of the Board of Directors and (z) does not govern the voting of Common
Stock held by persons other than those entities named above in this proviso,
then for purposes of this Article 13(c)(iv)(A), such voting agreement shall not
cause any such Person (or any of such Person's Affiliates or Associates) or all
of such Persons acting together to be the "beneficial owner" of, or to
"beneficially own," any securities owned by any other entity named above in this
proviso that are subject to such voting agreement; or

Corporation and at any time within the two-year period immediately prior to the
date in question was the beneficial owner, directly or indirectly, of Voting

to any shares of Voting Stock which were at any time within the two-year period
immediately prior to the date in question beneficially owned by an Interested
Stockholder, if such assignment or succession shall have occurred in the course
of a transaction or series of transactions not involving a public offering
within the meaning of the 1933 Act.

                           (v) A person shall be a "beneficial owner" of, shall
"beneficially own" and shall have "beneficial ownership" of any Capital Stock
(1) that such person or any of its Affiliates or Associates owns, directly or
indirectly; (2) that such person or any of its Affiliates or Associates has,
directly or indirectly, (x) the right to acquire (whether such right is
exercisable immediately or subject only to the passage of time), pursuant to any

upon the exercise of conversion rights, exchange rights, warrants or options, or
otherwise, or (y) the right to vote pursuant to any agreement, arrangement or
understanding; or (3) which is beneficially owned, directly or indirectly, by
any other person with which such person or any of its Affiliates or Associates
has any agreement, arrangement or understanding for the purpose of acquiring,
holding, voting or disposing of any shares of Capital Stock. For the purposes of
determining whether a person is an Interested Stockholder pursuant to paragraph
(iv) above, the number of shares of Capital Stock deemed to be outstanding shall
include shares deemed beneficially owned by such person through application of
this paragraph (v), but shall not include any other shares of Capital Stock that
may be issuable pursuant to any agreement, arrangement or understanding, or upon
exercise of conversion rights, warrants or options, or otherwise.

                           (vi) The terms "Affiliate" and "Associate" shall have
the respective meanings ascribed to such terms in Rule 12b-2 of the General
Rules and Regulations under the 1934 Act in effect on the date that this ARTICLE
13 (Fair Price) is approved by the Board of Directors of the Corporation (the
term "registrant" in Rule 12b-2 meaning in this case the Corporation).

                           (vii) The term "Subsidiary" means with reference to
any person, any corporation or other entity of which a majority of the voting
power of equity securities or majority of the equity interest is beneficially
owned, directly or indirectly, by such person, or otherwise controlled by such
person; provided, however, that for the purposes of the definition of Interested
Stockholder set forth in paragraph (iv) above, the term "Subsidiary" shall mean
only a corporation or other entity of which a majority of each class of equity
securities is beneficially owned by the Corporation.

                           (viii) "Common Stock" shall mean the common stock,
par value $0.01 per share, of the Corporation, except that "Common Stock" when
used with reference to any person other than the Corporation shall mean the
capital stock of such person with the greatest voting power, or the equity
securities or other equity interest having power to control or direct the
management, of such person.

                           (ix) The term "Disinterested Director," with respect
to any particular Business Combination with, or proposed by or on behalf of, any
Interested Stockholder or any Affiliate or Associate of any Interested
Stockholder or any person who thereafter would be an Affiliate or Associate of
any Interested Stockholder, means (1) any member of the Board of Directors of
the Corporation, while such person is a member of the Board of Directors, who is
not an Interested Stockholder, an Affiliate or Associate of an Interested
Stockholder, or a representative of an Interested Stockholder or of any such
Affiliate or Associate, and was a member of the Board of Directors prior to the
Effective Time, or (2) any person who subsequently becomes a member of the Board
of Directors, while such person is a member of the Board of Directors, who is
not an Interested Stockholder, an Affiliate or Associate of an Interested
Stockholder, or a representative of an Interested Stockholder or of any such
Affiliate or Associate, if such person's nomination for election or election to
the Board of Directors is recommended or approved by a majority of the
Disinterested Directors then in office.

                           (x) The term "Fair Market Value" means (1) in the
case of cash, the amount of such cash; (2) in the case of stock, the highest
closing sale price during the 30-day period immediately preceding the date in
question of a share of such stock on the Composite Tape for New York Stock
Exchange-listed stocks, or, if such stock is not quoted on the Composite Tape,
on the New York Stock Exchange, or, if such stock is not listed on such
exchange, on the principal United States securities exchange registered under
the 1934 Act on which such stock is listed, or, if such stock is not listed on
any such exchange, the highest closing sale price with respect to a share of
such stock during the 30-day period immediately preceding the date in question
as reported by the National Association of Securities Dealers, Inc. Automated
Quotation System or any similar system then in use, or if no such sale prices
are available, the highest of the means between the last reported bid and asked
price with respect to a share of such stock on each day during the 30-day period
immediately preceding the date in question as reported by the National
Association of Securities Dealers, Inc. Automated Quotation System, or if not so
reported, as determined by a member firm of the National Association of
Securities Dealers, Inc. selected by a majority of the Disinterested Directors,
or if no such bid and asked prices are available, the fair market value you on
the date in question of a share of such stock as determined in good faith by a
majority of the Disinterested Directors; and (3) in the case of property other
than cash or stock, the fair market value of such property on the date in
question as determined in good faith by a majority of the Disinterested
Directors.

                           (xi) In the event of any Business Combination in
which the Corporation survives, the phrase "consideration other than cash to be
received" as used in paragraphs (1) and (2) of Section (b)(ii)(A) of this
ARTICLE 13 (Fair Price -- Minimum Price Requirements) shall include the shares
of Common Stock and/or the shares of any other class or series of Capital Stock
retained by the holders of such shares.

                           (xii) The term "Announcement Date" means the date on
which the proposed Business Combination is first publicly announced, disclosed
or reported.

                           (xiii) The term "Determination Date" means with
respect to any Interested Stockholder, the date on which such Interested
Stockholder became an Interested Stockholder.

                           (xiv) "Business Day" shall mean any day other than a
Saturday, Sunday or a day on which banking institutions in the State of Texas
are authorized or obligated by law or executive order to close.

                  (d) Powers of Directors. For the purpose of this ARTICLE 13
(Fair Price), a majority of the Disinterested Directors (whether or not any
vacancies then exist on the Board of Directors) shall exercise the powers of the
Disinterested Directors hereunder, and shall have the power and duty to
determine in good faith, on the basis of information known to them after
reasonable inquiry, all questions arising under this ARTICLE 13 (Fair Price),
including, without limitation, (1) whether a person is an Interested
Stockholder, (2) the number of shares of Capital Stock beneficially owned by any
person, (3) whether a person is an Affiliate or Associate of another, (4)

<PAGE>   15




Stockholder or an Affiliate or Associate of an Interested Stockholder or a
person who thereafter would be an Interested Stockholder or an Affiliate or
Associate of an Interested Stockholder, and (5) whether any transaction
specified in paragraph (i)(B) of Section (c) of this ARTICLE 13 (Fair Price --
Certain Definitions) meets the Substantial Part test set forth therein. Any such
determination made in good faith shall be binding and conclusive on all parties.

                  (e) No Effect On Fiduciary Obligations.

                      (i) Nothing contained in this ARTICLE 13 (Fair Price)
shall be construed to relieve any Interested Stockholder from any fiduciary
obligation imposed by law.

                      (ii) The fact that any Business Combination complies with
the provisions of Section (b) of this ARTICLE 13 (Fair Price -- When Special
Vote Not Required) shall not be construed to impose any fiduciary duty,
obligation or responsibility on the Board of Directors, or any member thereof,
to approve such Business Combination or recommend its adoption or approval to
the stockholders of the Corporation, nor shall such compliance limit, prohibit
or otherwise restrict in any manner the Board of Directors, or any member
thereof, with respect to evaluations of or actions and responses taken with
respect to such Business Combination.

or by mail, by or at the direction of the Chairman of the Board and Chief
Executive Officer, the Secretary, or the officer or person(s) calling the

waiver of notice, in person or by proxy.

         Such notice shall also comply with relevant provisions contained in the
Certificate of Incorporation filed on behalf of the Corporation.

         2.5 Conduct of Business. This Section 2.5 of this ARTICLE TWO
((Meetings of Stockholders -- Conduct of Business) shall be effective
immediately following the consummation of the initial public offering of the
Corporation's Common Stock pursuant to a registration statement declared
effective under the Securities Act of 1933, as amended. No business may be
transacted at any meeting of stockholders, other than business that is either
(x) specified in the notice of meeting (or any supplement thereto) given by or
at the direction of the Board of Directors (or any duly authorized committee
thereof), (y) otherwise properly brought before the meeting by or at the
direction of the Board of Directors (or any duly authorized committee thereof)
or (z) otherwise properly brought before the meeting by any stockholder of the
Corporation who is a stockholder of record on the date of such meeting, on the
date of the giving of the notice provided for in this Section 2.5 of this
ARTICLE TWO (Meetings of Stockholders -- Conduct of Business), and on the record
date for the determination of stockholders entitled to vote at such meeting and
who complies with the procedures set forth in this Section 2.5 of this ARTICLE
TWO (Meetings of Stockholders -- Conduct of Business).

         Nominations of persons for election to the Board of Directors and the
proposal of business to be transacted by the stockholders may be made at an
annual meeting of stockholders only (a) pursuant to the Corporation's notice
with respect to such meeting, (b) by or at the direction of the Board of
Directors or (c) by any stockholder of record of the Corporation who was a
stockholder of record at the time of the giving of the notice provided for in
the following paragraph, who is entitled to vote at the meeting and who has
complied with the notice procedures set forth in this Section 2.5 of this
ARTICLE TWO (Meetings of Stockholders -- Conduct of Business).

         For nominations or other business to be properly brought before an
annual meeting by a stockholder pursuant to clause (c) of the foregoing

to the Secretary of the Corporation, (2) such business must be a proper matter
for stockholder action under the Delaware Corporation Law, (3) if the
stockholder, or


                                      - 2 -

<PAGE>   7

the beneficial owner on whose behalf any such proposal or nomination is made,
has provided the Corporation with a Solicitation Notice, as that term is defined
in subclause (c)(iii) of this paragraph, such stockholder or beneficial owner
must, in the case of a proposal, have delivered a proxy statement and form of
proxy to holders of at least the percentage of the Corporation's voting shares
required under applicable law to carry any such proposal, or, in the case of a
nomination or nominations, have delivered a proxy statement and form of proxy to
holders of a percentage of the Corporation's voting shares reasonably believed
by such stockholder or beneficial holder to be sufficient to elect the nominee
or nominees proposed to be nominated by such stockholder, and must, in either
case, have included in such materials the Solicitation Notice and (4) if no
Solicitation Notice relating thereto has been timely provided pursuant to this
Section 2.5 of this ARTICLE TWO (Meetings of Stockholders -- Conduct of
Business), the stockholder or beneficial owner proposing such business or
nomination must not have solicited a number of proxies sufficient to have
required the delivery of such a Solicitation Notice under this Section 2.5 of
this ARTICLE TWO (Meetings of Stockholders -- Conduct of Business). To be
timely, a stockholder's notice shall be delivered to the Secretary at the
principal executive offices of the Corporation not less than 45 or more than 75
days prior to the first anniversary (the "ANNIVERSARY") of the date on which the
Corporation first mailed its proxy materials for the preceding year's annual
meeting of stockholders; provided, however, that if the date of the annual
meeting is advanced more than 30 days prior to or delayed by more than 30 days
after the anniversary of the preceding year's annual meeting, notice by the
stockholder to be timely must be so delivered not later than the close of
business on the later of (i) the 90th day prior to such annual meeting or (ii)
the 10th day following the day on which public announcement of the date of such
meeting is first made. Such stockholder's notice shall set forth (a) as to each
person whom the stockholder proposes to nominate for election or reelection as a
director all information relating to such person as would be required to be
disclosed in solicitations of proxies for the election of such nominees as
directors pursuant to Regulation 14A under the Securities Exchange Act of 1934,
as amended and including any successor provisions thereto (the "EXCHANGE ACT"),
and such person's written consent to serve as a director if elected; (b) as to
any other business that the stockholder proposes to bring before the meeting, a
brief description of such business, the reasons for conducting such business at
the meeting and any material interest in such business of such stockholder and
the beneficial owner, if any, on whose behalf the proposal is made; (c) as to
the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made (i) the name and address of such
stockholder, as they appear on the Corporation's books, and of such beneficial
owner, (ii) the class and number of shares of the Corporation that are owned
beneficially and of record by such stockholder and such beneficial owner, and
(iii) whether either such stockholder or beneficial owner intends to deliver a
proxy statement and form of proxy to holders of, in the case of a proposal, at
least the percentage of the Corporation's voting shares required under
applicable law to carry the proposal or, in the case of a nomination or
nominations, a sufficient number of holders of the Corporation's voting shares
to elect such nominee or nominees (an affirmative statement of such intent, a
"SOLICITATION NOTICE").

         Notwithstanding anything in the second sentence of the third paragraph
of this Section 2.5 of this ARTICLE TWO (Meetings of Stockholders -- Conduct of
Business) to the contrary, in the event that the number of directors to be
elected to the Board of Directors is increased and there is


                                      - 3 -

<PAGE>   8

no public announcement naming all of the nominees for director or specifying the
size of the increased Board of Directors made by the Corporation at least 55
days prior to the Anniversary, a stockholder's notice required by this Bylaw
shall also be considered timely, but only with respect to nominees for any new
positions created by such increase, if it shall be delivered to the Secretary at
the principal executive offices of the Corporation not later than the close of
business on the 10th day following the day on which such public announcement is
first made by the Corporation.

         Only persons nominated in accordance with the procedures set forth in
this Section 2.5 of this ARTICLE TWO (Meetings of Stockholders -- Conduct of
Business) shall be eligible to serve as directors and only such business shall
be conducted at an annual meeting of stockholders as shall have been brought
before the meeting in accordance with the procedures set forth in this Section
2.5 of this ARTICLE TWO (Meetings of Stockholders -- Conduct of Business). The
chair of the meeting shall have the power and the duty to determine whether a
nominee or any business proposed to be brought before the meeting has been made
in accordance with the procedures set forth in these Bylaws and, if any proposed
nominee or business is not in compliance with these Bylaws, to declare that such
defective proposed business or nomination shall not be presented for stockholder
action at the meeting and shall be disregarded.

         Only such business shall be conducted at a special meeting of
stockholders as shall have been brought before the meeting pursuant to the
Corporation's notice of meeting. Nominations of persons for election to the
Board of Directors may be made at a special meeting of stockholders at which
directors are to be elected pursuant to the Corporation's notice of meeting only
(a) by or at the direction of the Board of Directors or (b) by any stockholder
of record of the Corporation who is a stockholder of record at the time of
giving of notice provided for in this paragraph, who shall be entitled to vote
at the meeting and who complies with the notice procedures set forth in this
Section 2.5 of this ARTICLE TWO (Meetings of Stockholders -- Conduct of
Business). Nominations by stockholders of persons for election to the Board of
Directors may be made at such a special meeting of stockholders if the
stockholder's notice required by the third paragraph of this Section 2.5 of this
ARTICLE TWO (Meetings of Stockholders -- Conduct of Business) shall be delivered
to the Secretary at the principal executive offices of the Corporation not later
than the close of business on the later of (i) the 90th day prior to such
special meeting or (ii) the 10th day following the day on which public
announcement is first made of the date of the special meeting and of the
nominees proposed by the Board of Directors to be elected at such meeting.

         For purposes of this Section 2.5 of this ARTICLE TWO (Meetings of
Stockholders -- Conduct of Business), "PUBLIC ANNOUNCEMENT" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or a comparable national news service or in a document publicly filed by
the Corporation with the Securities and Exchange Commission pursuant to Sections
13, 14 or 15(d) of the Exchange Act.

         Notwithstanding the foregoing provisions of this Section 2.5 of this
ARTICLE TWO (Meetings of Stockholders -- Conduct of Business), a stockholder
shall also comply with all applicable requirements of the Exchange Act and the
rules and regulations thereunder with respect


                                      - 4 -

<PAGE>   9

to matters set forth in this Section 2.5 of this ARTICLE TWO (Meetings of
Stockholders -- Conduct of Business). Nothing in this Section 2.5 of this
ARTICLE TWO (Meetings of Stockholders -- Conduct of Business) shall be deemed to
affect any rights of stockholders to request inclusion of proposals in the
Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act.

         In addition, a person providing notice under Section 2.5 of this
ARTICLE TWO (Meetings of Stockholders -- Conduct of Business) shall
supplementally and promptly provide such other information as the Corporation
otherwise reasonably requests.

         A majority of the Board of Directors may reject any business proposed
by a stockholder that is not timely made or otherwise not made in accordance
with the terms of Section 2.5 of this ARTICLE TWO (Meetings of Stockholders --
Conduct of Business). If a majority of the Board of Directors reasonably
determines that the information provided in a stockholder's notice does not
satisfy the informational requirements of Section 2.5 of this ARTICLE TWO
(Meetings of Stockholders -- Conduct of Business) in any material respect, then
the Secretary of the Corporation shall promptly notify such stockholder of the
deficiency in writing. The stockholder shall have an opportunity to cure the
deficiency by providing additional information to the Secretary within such
period of time as a majority of the Board of Directors shall reasonably
determine, which period shall not exceed 10 days from the date such deficiency
notice is given to the stockholder. If the deficiency is not cured within such
period, or if a majority of the Board of Directors reasonably determines that
the additional information provided by the stockholder, together with the
information previously provided, does not satisfy the requirements of this
paragraph in any material respect, then a majority of the Board of Directors may
reject such stockholder's proposed business. The Secretary of the Corporation
shall notify a stockholder in writing whether his or her proposal of new
business has been made in accordance with the time and information requirements
of Section 2.5 of this ARTICLE TWO (Meetings of Stockholders -- Conduct of
Business).

         Once business has been properly brought before the meeting in
accordance with this Section 2.5 of this ARTICLE TWO (Meetings of Stockholders
- -- Conduct of Business), nothing herein shall be deemed to preclude discussion
by any stockholder of any such business; provided further, however, that if the
stockholder bringing such matter before the meeting withdraws such matter, such
matter shall no longer be properly before the meeting.

         The chairman of a meeting of stockholders may, if the facts warrant,
determine and declare to the meeting that business was not properly brought
before the meeting in accordance with the procedure prescribed by Section 2.5 of
this ARTICLE TWO (Meetings of Stockholders -- Conduct of Business) and if the
chairman should so determine, he or she shall so declare to the meeting and such
business shall not be transacted.

         Notwithstanding anything in these Bylaws to the contrary, no business
shall be conducted, and no person shall be nominated to serve as a director, at
an annual or special meeting of stockholders, unless the requirements of the
Certificate of Incorporation shall have been satisfied.

         2.6 Voting List. At least 10 days before each meeting of stockholders,
the Secretary or other officer of the Corporation who has charge of the
Corporation's stock ledger, either directly or through another officer appointed
by him or through a transfer agent appointed by the Board of Directors, shall
prepare a complete list of stockholders entitled to vote thereat, arranged in
alphabetical order and showing the address of each stockholder and number of
shares of capital stock registered in the name of each stockholder. For a period
of 10 days prior to such meeting, such list shall be kept on file at a place
within the city where the meeting is to be held, which place shall be specified
in the notice of meeting or a duly executed waiver of notice of such meeting or,
if not so specified, at the place where the meeting is to be held and shall be
open to examination by any stockholder, for any purpose germane to the meeting,
during ordinary business hours. Such list shall be produced at such meeting and
kept at the meeting at all times during such meeting and may be inspected by any
stockholder who is present.

         2.7 Quorum. The holders of a majority of the outstanding shares of
capital stock entitled to vote on a matter, present in person or by proxy, shall
constitute a quorum at any meeting of stockholders, except as otherwise provided
by law, the Certificate of Incorporation, or these Bylaws. If a quorum shall not
be present, in person or by proxy, at any meeting of stockholders, the chairman
of the meeting or the stockholders entitled to vote thereat who are present, in
person or by proxy, may adjourn the meeting from time to time without notice
other than announcement at the meeting (unless the Board of Directors, after
such adjournment, fixes a new record date for the adjourned meeting), until a
quorum shall be present, in person or by proxy. At any adjourned meeting at
which a quorum shall be present, in person or by proxy, any business may be
transacted which may have been transacted at the original meeting had a quorum
been present; provided that, if the adjournment is for more than 30 days or if
after the adjournment a new record date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given to each stockholder of record
entitled to vote at the adjourned meeting.

         2.8 Required Vote; Withdrawal of Quorum. When a quorum is present at
any meeting, the vote of the holders of at least a majority of the outstanding
shares of capital stock entitled to vote thereat who are present, in person or
by proxy, shall decide any question brought before such meeting, unless the
question is one on which, by express provision of law, the Certificate of
Incorporation, or these Bylaws, a different vote is required, in which case such
express provision shall govern and control the decision of such question;
provided, however, that the vote of the holders of a plurality of the
outstanding shares of capital stock entitled to vote in the election of
directors who are present, in person or by proxy, shall be required to effect
elections of directors. The stockholders present at a duly constituted meeting
may continue to transact business until adjournment, notwithstanding the
withdrawal of enough stockholders to leave less than a quorum.

         2.9 Method of Voting; Proxies. Except as otherwise provided in the
Certificate of Incorporation (including any certificate establishing a series of
Preferred Stock) or by law, each outstanding share of capital stock, regardless
of class, shall be entitled to one vote on each matter submitted to a vote at a
meeting of stockholders. Elections of directors need not be by written ballot.
At any meeting of stockholders, every stockholder having the right to vote may
vote either in person or by a proxy executed in writing by the stockholder or by
his duly authorized attorney-in-fact. Each


                                      - 6 -

<PAGE>   11

such proxy shall be filed with the Secretary of the Corporation before or at the
time of the meeting. No proxy shall be valid after three years from the date of
its execution, unless otherwise provided in the proxy. If no date is stated in a
proxy, such proxy shall be presumed to have been executed on the date of the
meeting at which it is to be voted. Each proxy shall be revocable unless
expressly provided therein to be irrevocable and coupled with an interest
sufficient in law to support an irrevocable power or unless otherwise made
irrevocable by law.

         2.10 Record Date. For the purpose of determining stockholders entitled
(a) to notice of or to vote at any meeting of stockholders or any adjournment
thereof, (b) to receive payment of any dividend or other distribution or
allotment of any rights, or (c) to exercise any rights in respect of any change,
conversion, or exchange of stock or for the purpose of any other lawful action,
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted by
the Board of Directors, for any such determination of stockholders, such date in
any case to be not more than 60 days and not less than 10 days prior to such
meeting nor more than 60 days prior to any other action. If no record date is
fixed:

                  (i) The record date for determining stockholders entitled to
         notice of or to vote at a meeting of stockholders shall be at the close
         of business on the day next preceding the day on which notice is given
         or, if notice is waived, at the close of business on the day next
         preceding the day on which the meeting is held.

                  (ii) The record date for determining stockholders for any
         other purpose shall be at the close of business on the day on which the
         Board of Directors adopts the resolution relating thereto.

         A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

         2.11 Conduct of Meeting. The Chairman of the Board and Chief Executive
Officer, if such office has been filled, and, if such office has not been filled

stockholders and act as the chairman of the meeting. The chairman of the meeting
shall have the power to adjourn the meeting to another place, date, and time.
The chairman of the meeting shall determine the order of business and the
procedure at the meeting, including such regulation of the manner of voting and
the conduct of discussion as seem to him or her in order. The Secretary shall
keep the records of each meeting of stockholders. In the absence or inability to
act of any such officer, such officer's duties shall be performed by the officer
given the authority to act for such absent or non-acting officer under these
Bylaws or by resolution adopted by the Board of Directors, or if no officer has
been given such authority, by some person appointed at the meeting.

         2.12 Inspectors. The Board of Directors shall, if required, in advance
of any meeting of stockholders, appoint one or more inspectors to act at such
meeting or any adjournment thereof. If any of the inspectors so appointed shall
fail to appear or act, the chairman of the meeting shall, or


                                      - 7 -

appoint one or more inspectors. Each inspector, before entering upon the
discharge of his duties, shall take and sign an oath to execute faithfully the
duties of inspector at such meeting with strict impartiality and according to
the best of his ability. The inspectors shall determine the number of shares of
capital stock of the Corporation outstanding and the voting power of each, the
number of shares represented at the meeting, the existence of a quorum, and the
validity and effect of proxies and shall receive votes, ballots, or consents,
hear and determine all challenges and questions arising in connection with the
right to vote, count, and tabulate all votes, ballots, or consents, determine
the results, and do such acts as are proper to conduct the election or vote with
fairness to all stockholders. On request of the chairman of the meeting, the
inspectors shall make a report in writing of any challenge, request, or matter
determined by them and shall execute a certificate of any fact found by them. No

majority of those present or any director solely present may adjourn the meeting
from time to time without further notice. Unless the act of a greater number is
required by law, the Certificate of Incorporation, or these Bylaws, the act of a
majority of the directors present at a meeting at which a quorum is in
attendance shall be the act of the Board of Directors. At any time that the
Certificate of Incorporation provides that directors elected by the holders of a
class or series of stock shall have more or less than one vote per director on
any matter, every reference in these Bylaws to a majority or other proportion of
directors shall refer to a majority or other proportion of the votes of such

at which a quorum is in attendance shall be the act of a committee, unless the
act of a greater number is required by law, the Certificate of Incorporation, or
these Bylaws.

         4.9 Minutes. Each committee shall cause minutes of its proceedings to
be prepared and shall report the same to the Board of Directors upon the request

minute books of the Corporation.

Directors, be allowed a fixed sum and expenses of attendance, if any, for

         5.1 Method. Whenever by statute, the Certificate of Incorporation, or
these Bylaws, notice is required to be given to any committee member, director,
or stockholder and no provision is made as to how such notice shall be given,
personal notice shall not be required and any such notice may be given (a) in
writing, by mail, postage prepaid, addressed to such committee member, director,
or stockholder at his address as it appears on the books or (in the case of a
stockholder) the stock transfer records of the Corporation, or (b) by any other
method permitted by law (including but not limited to overnight courier service,
telegram, telex, or telefax). Any notice required or permitted to be given by
mail shall be deemed to be delivered and given at the time when the same is
deposited in the United States mail as aforesaid. Any notice required or

stockholder, director, or committee member of the Corporation by statute, the
Certificate of Incorporation, or these Bylaws, a waiver thereof in writing
signed by the person or persons entitled to such notice, whether before or after

shall be a Chairman of the Board and Chief Executive Officer, a President, a
Secretary, and such other officers as the Board of Directors may from time to
time elect or appoint, including one or more Vice Presidents (with each Vice
President to have such descriptive title, if any, as the Board of Directors

Directors may be removed by the Board of Directors whenever in its judgment the
best interest of the Corporation will be served thereby, but such removal shall
be without prejudice to the contract rights, if any, of the person so removed.
Election or appointment of an officer or agent shall not of itself create
contract rights.

(by death, resignation, removal, or otherwise) may be filled by the Board of
Directors.

         6.4 Authority. Officers shall have such authority and perform such

shall be fixed from time to time by the Board of Directors; provided, however,

delegated) to the Chairman of the Board and Chief Executive Officer or the
President.

Officer, the President shall

<PAGE>   17

exercise all of the powers and discharge all of the duties of the Chairman of
the Board and Chief Executive Officer. As between the Corporation and third
parties, any action taken by the President in the performance of the duties of
the Chairman of the Board and Chief Executive Officer shall be conclusive
evidence that the Chairman of the Board and Chief Executive Officer is absent or
unable to act. The President may sign all certificates for shares of stock of
the Corporation.

determination, as determined by the length of time they have held the office of
Vice President) shall exercise the powers of the President during that officer's
absence or inability to act. As between the Corporation and third parties, any
action taken by a Vice President in the performance of the duties of the
President shall be conclusive evidence of the absence or inability to act of the
President at the time such action was taken.

         6.9 Treasurer. The Treasurer shall have custody of the Corporation's
funds and securities, shall keep full and accurate account of receipts and
disbursements, shall deposit all monies and valuable effects in the name and to
the credit of the Corporation in such depository or depositories as may be
designated by the Board of Directors, and shall perform such other duties as may
be prescribed by the Board of Directors, the Chairman of the Board and Chief
Executive Officer, or the President.

         6.10 Assistant Treasurers. Each Assistant Treasurer shall have such
powers and duties as may be assigned to him by the Board of Directors, the
Chairman of the Board and Chief Executive Officer, or the President. The
Assistant Treasurers (in the order of their seniority as determined by the Board
of Directors or, in the absence of such a determination, as determined by the
length of time they have held the office of Assistant Treasurer) shall exercise
the powers of the Treasurer during that officer's absence or inability to act.

         6.11 Secretary. Except as otherwise provided in these Bylaws, the
Secretary shall keep the minutes of all meetings of the Board of Directors and
of the stockholders in books provided for that purpose, and he shall attend to

Board and Chief Executive Officer or the President, in the name of the

office of the Corporation during business hours. He shall in general perform all
duties incident to the office of the Secretary, subject to the control of the
Board of Directors, the Chairman of the Board and Chief Executive Officer, and
the President.

         6.12 Assistant Secretaries. Each Assistant Secretary shall have such
powers and duties as may be assigned to him by the Board of Directors, the
Chairman of the Board and Chief Executive Officer, or the President. The
Assistant Secretaries (in the order of their seniority as determined by


                                     - 13 -

<PAGE>   18

the Board of Directors or, in the absence of such a determination, as determined
by the length of time they have held the office of Assistant Secretary) shall
exercise the powers of the Secretary during that officer's absence or inability
to act.

         6.13 Vice Chairman of the Board. The Vice Chairman of the Board, if one

Corporation shall be in such form as shall be approved by the Board of
Directors. The certificates shall be signed by the Chairman of the Board and
Chief Executive Officer or the President or a Vice President and also by the
Secretary or an Assistant Secretary or by the Treasurer or an Assistant
Treasurer. Any and all signatures on the certificate may be a facsimile and may
be sealed with the seal of the Corporation or a facsimile thereof. If any
officer, transfer agent, or registrar who has signed, or whose facsimile
signature has been placed upon, a certificate has ceased to be such officer,
transfer agent, or registrar before such certificate is issued, such certificate
may be issued by the Corporation with the same effect as if he were such
officer, transfer agent, or registrar at the date of issue. The certificates
shall be consecutively numbered and shall be entered in the books of the
Corporation as they are issued and shall exhibit the holder's name and the
number of shares.

         7.2 Replacement of Lost or Destroyed Certificates. The Corporation may
direct a new certificate or certificates to be issued in place of a certificate
or certificates theretofore issued by the Corporation and alleged to have been
lost or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate or certificates representing shares to be lost or
destroyed. When authorizing such issue of a new certificate or certificates the
Board of Directors may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost or destroyed certificate or
certificates, or his legal representative, to advertise the same in such manner
as it shall require and/or to give the Corporation a bond with a surety or
sureties satisfactory to the Corporation in such sum as it may direct as
indemnity against any claim, or expense resulting from a claim, that may be made
against the Corporation with respect to the certificate or certificates alleged
to have been lost or destroyed.

         7.3 Transfer of Shares. Shares of stock of the Corporation shall be
transferable only on the books of the Corporation by the holders thereof in
person or by their duly authorized attorneys or legal representatives. Upon
surrender to the Corporation or the transfer agent of the Corporation of a
certificate representing shares duly endorsed or accompanied by proper evidence
of succession, assignment, or authority to transfer, the Corporation or its
transfer agent shall issue a new certificate to the person entitled thereto,
cancel the old certificate, and record the transaction upon its books.

         7.4 Registered Stockholders. The Corporation shall be entitled to treat
the holder of record of any share or shares of stock as the holder in fact
thereof and, accordingly, shall not be bound to recognize any equitable or other
claim to or interest in such share or shares on the part of


                                     - 14 -

any other person, whether or not it shall have express or other notice thereof,

to provide that certificates representing shares of stock bear such legends as
the Board of Directors deems appropriate to assure that the Corporation does not
become liable for violations of federal or state securities laws or other
applicable law.

                     ARTICLE EIGHT: MISCELLANEOUS PROVISIONS

         8.1 Dividends. Subject to provisions of law and the Certificate of
Incorporation, dividends may be declared by the Board of Directors at any
regular or special meeting and may be paid in cash, in property, or in shares of

discretion of the Board of Directors.

         8.2 Reserves. There may be created by the Board of Directors out of
funds of the Corporation legally available therefor such reserve or reserves as
the directors from time to time, in their discretion, consider proper to provide
for contingencies, to equalize dividends, or to repair or maintain any property
of the Corporation, or for such other purpose as the Board of Directors shall
consider beneficial to the Corporation, and the Board of Directors may modify or
abolish any such reserve in the manner in which it was created.

         8.3 Books and Records. The Corporation shall keep correct and complete

by so stating at any meeting of the Board of Directors or by giving written
notice to the Board of Directors, the Chairman of the Board and Chief Executive
Officer, the President, or the Secretary. Such resignation shall take effect at

                                     - 15 -

Chief Executive Officer or the President shall have the power and authority to

respect to any securities of another issuer which may be held or owned by the
Corporation and to make, execute, and deliver any waiver, proxy, or consent with
respect to any such securities.

similar communications equipment by means of which persons participating in the
meeting can hear each other, and participation in a meeting pursuant to this
Section 8.8 of this ARTICLE EIGHT (Miscellaneous Provisions -- Telephone
Meetings) shall constitute presence in person at such meeting, except where a
person participates in the meeting for the express purpose of objecting at the
beginning of such meeting to the transaction of any business on the ground that
the meeting is not lawfully called or convened.

         8.9 Action Without a Meeting. Unless otherwise restricted by the
Certificate of Incorporation or by these Bylaws, any action required or
permitted to be taken at a meeting of the Board of Directors, or of any
committee of the Board of Directors, may be taken without a meeting if a consent
or consents in writing, setting forth the action so taken, shall be signed by
all the directors or all the committee members, as the case may be, entitled to
vote with respect to the subject matter thereof, and such consent shall have the
same force and effect as a vote of such directors or committee members, as the
case may be, and may be stated as such in any certificate or document filed with
the Secretary of State of the State of Delaware or in any certificate delivered
to any person. Such consent or consents shall be filed with the minutes of
proceedings of the Board of Directors or committee, as the case may be.

         Effective immediately following the consummation of the initial public
offering of the Corporation's Common Stock pursuant to a registration statement
declared effective under the Securities Act of 1933, as amended and including

or special meeting of stockholders of the Corporation and may not be effected by
any consent in writing by such stockholders.

         8.10 Invalid Provisions. If any part of these Bylaws shall be held
invalid or inoperative for any reason, the remaining parts, so far as it is
possible and reasonable, shall remain valid and operative.

         8.11 Mortgages, etc. With respect to any deed, deed of trust, mortgage,
or other instrument executed by the Corporation through its duly authorized
officer or officers, the attestation to such execution by the Secretary of the
Corporation shall not be necessary to constitute such deed, deed of trust,
mortgage, or other instrument a valid and binding obligation against the
Corporation unless


                                     - 16 -

<PAGE>   21

the resolutions, if any, of the Board of Directors authorizing such execution
expressly state that such attestation is necessary.

         8.12 Headings. The headings used in these Bylaws have been inserted for

of at least two-thirds of the Directors then serving, make, adopt, alter, amend,
and repeal from time to time these Bylaws and make from time to time new Bylaws
of the Corporation (subject to the right of the stockholders entitled to vote
thereon to adopt, alter, amend, and repeal Bylaws made by the Board of Directors
or to make new Bylaws); provided, however, that the stockholders of the
Corporation may adopt, alter, amend, or repeal Bylaws made by the Board of
Directors or make new Bylaws solely upon the affirmative vote of the holders of
at least 80% of the outstanding shares of capital stock then entitled to vote
thereon.

         8.15 Ratification. Any transaction questioned in any lawsuit on the
grounds of, among other things, lack of authority, defective or irregular
execution, adverse interest of a director, officer or stockholder,
non-disclosure, miscomputation, or the application of improper principles or
practices of accounting, may be ratified, before or after judgment, by the Board
of Directors or by the stockholders, and if so ratified shall have the same
force and effect as if the questioned transaction had been originally duly
authorized. Such ratification shall be binding upon the Corporation and its
stockholders and shall constitute a bar to any claim or execution of any
judgment in respect of such questioned transaction.

         8.16 Contracts. The Board of Directors may authorize any person or
persons, in the name and on behalf of the Corporation, to enter into or execute
and deliver any and all deeds, bonds, mortgages, contracts and other obligations

Re: Alamosa PCS Holdings, Inc. Registration Statement on Form S-1

Gentlemen:

We have acted as counsel to Alamosa PCS Holdings, Inc., a Delaware corporation
(the "Company"), in connection with the preparation of the Company's
Registration Statement on Form S-1 (Registration No. 333-89995) and the
amendments thereto (the Registration Statement, as amended, is hereinafter
referred to as the "Registration Statement") filed with the Securities and
Exchange Commission under the Securities Act of 1933, as amended (the
"Securities Act"). The Registration Statement relates to the offer and sale by
the Company of up to 12,321,100 shares of its Common Stock, par value $0.01 per
share ("Common Stock"). The opinions expressed herein relate solely to, are
based solely upon and are limited exclusively to, the internal substantive laws
of the State of Texas, the General Corporation Laws of the State of Delaware and
applicable federal laws of the United States of America.

In connection therewith, we have examined and relied upon the original, or
copies certified to our satisfaction, of (i) the Amended and Restated
Certificate of Incorporation of the Company (the "Certificate of
Incorporation"), and the Amended and Restated Bylaws of the Company (the
"Bylaws"); (ii) the minutes and records of the corporate proceedings of the
Company with respect to the issuance by the Company of the shares of Common
Stock; (iii) the Registration Statement and all exhibits thereto; (iv) the form
of Underwriting Agreement (herein so called), to be entered into among the
Company and Salomon Smith Barney Inc., Credit Suisse First Boston Corporation
and Deutsche Bank Securities Inc., as Underwriters named in the Underwriting
Agreement; (v) such other documents and instruments as we have deemed necessary
for the expression of the opinions contained herein and (vi) the specimen Common
Stock certificate filed as Exhibit 4.1 to the Registration Statement.

In making the foregoing examinations, we have assumed the genuineness of all
signatures and the authenticity of all documents submitted to us as originals,
and the conformity to original documents of all documents submitted to us as
certified or photostatic copies thereof. As to various questions of fact
material to this opinion, where such facts have not been independently
established, and as to the content and form of certain minutes, records,
resolutions and other documents or writings of the Company, we have relied, to
the extent we have deemed reasonably appropriate, upon representations or
certificates of officers of

the Company or governmental officials. We have assumed that the Underwriting
Agreement will be executed in substantially the same form submitted to us.
Finally, we have assumed that all formalities required by the Company's
Certificate of Incorporation, Bylaws and the Delaware General Corporation Law
will be complied with when the shares of Common Stock are issued.

Based upon the foregoing, and having due regard for such legal considerations as
we deem relevant, we are of the opinion that the shares of Common Stock, upon
receipt by the Company of the full consideration for the shares of Common Stock
in accordance with the terms of the Underwriting Agreement, will be validly
issued, fully paid and nonassessable.

We hereby consent to the filing of this opinion with the Securities and Exchange
Commission as Exhibit 5.1 to the Registration Statement and any abbreviated
registration statements relating thereto that may be filed to register
additional securities identical to those covered by the Registration Statement
(including a registration statement filed pursuant to Rule 462(b) under the
Securities Act), and to the reference to our firm under the caption "Legal
Matters" in the prospectus constituting a part of such Registration Statement.
In giving such consent, we do not hereby admit that we are in the category of
persons whose consent is required under Section 7 of the Securities Act.


Very truly yours,




Haynes and Boone, LLP

Borrower to the Original Administrative Agent in connection with the Original
Credit Agreement.

         C. The Borrower, Alamosa Texas and Alamosa Wisconsin have entered into
various agreements with Sprint PCS relating to the construction and operation of
PCS systems in the Service Area.

         D. The Borrower desires to amend and restate the advancing term loan
facilities under the original Credit Agreement and to obtain advancing term loan
facilities in the aggregate principal amount of $250,000,000 to finance a
portion of its costs to construct and operate such PCS systems.

excluding the date the same is paid in full. Interest payable at the Default

the extent that Nortel Networks is a Lender under this Agreement, the Borrower
further hereby irrevocably agrees that each Loan to be advanced by Nortel
Networks to the Borrower in accordance with this Agreement (and only in
accordance with this Agreement and after the Administrative Agent's receipt of a
Notice of Borrowing executed by the Borrower) may (in the discretion of Nortel
Networks and if and to the extent that the proceeds of such Loan are to be paid

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

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

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

Reserve System).

         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

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.


CREDIT AGREEMENT - Page 40

         (a) Notwithstanding anything to the contrary contained in this
Agreement, each of the Commitments shall automatically terminate upon the

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,

outstanding principal amounts of such Commitments).

         (c) Notwithstanding anything to the contrary contained in this
Agreement, each of the Tranche A Commitments, the Tranche B Commitments and 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 _____ Business
Days' prior written notice of such election to the Administrative Agent,

         (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

                                    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 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,


CREDIT AGREEMENT - Page 42
<PAGE>   50

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
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


CREDIT AGREEMENT - Page 43
<PAGE>   51

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 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


CREDIT AGREEMENT - Page 44
<PAGE>   52

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


CREDIT AGREEMENT - Page 45
<PAGE>   53

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 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


CREDIT AGREEMENT - Page 46
<PAGE>   54

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
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;


CREDIT AGREEMENT - Page 47
<PAGE>   55

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 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:


CREDIT AGREEMENT - Page 48
<PAGE>   56

         (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 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


CREDIT AGREEMENT - Page 49
<PAGE>   57

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 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.

                                    ARTICLE 5

         (c) all cash and non-cash proceeds and products of any of the
foregoing.

         Section 5.2 Guaranties. (a) Holdings and each of the Operating

         (b) cause each such Subsidiary to Guarantee the payment and performance

CREDIT AGREEMENT - Page 51
<PAGE>   59

Contemporaneously with the issuance of any additional Capital Stock of the

Borrower, Holdings and the Operating Subsidiaries shall, or shall cause Holdings
or the appropriate Subsidiary of Holdings or the Borrower to (as applicable),

Administrative Agent and the Lenders, a perfected, first priority security
interest in all Capital Stock or other ownership interests in the Borrower or
any Subsidiary of Holdings or the Borrower, other than Capital Stock of an
Unrestricted Subsidiary of Holdings, owned by the Borrower or Holdings or any
such Subsidiary of Holdings or the Borrower (to the extent such Capital Stock or
other ownership interests are already not so pledged to the Administrative
Agent). Each of the Borrower, Holdings and the Operating Subsidiaries covenants
that none of the Capital Stock to be pledged in accordance with this Section 5.3
shall be subject to any transfer restriction, shareholders' agreement or other
restriction except for such restrictions under applicable securities laws, such
restrictions existing as of the Closing Date which have been disclosed to the
Administrative Agent in the Security Documents and such restrictions, if any, as
may be reasonably acceptable to the Administrative Agent. In connection with and
in addition to the foregoing, each of the Loan Parties shall, and shall cause
each other appropriate Person (as applicable) to, execute and/or deliver such
further agreements, documents and instruments (including, without limitation,
stock certificates, stock powers and financing statements) as the Administrative
Agent may reasonably request in order for it to obtain and maintain the

The Borrower, Holdings and the Operating Subsidiaries shall, and shall cause
each of the other Loan Parties to, on the Closing Date (with respect to any fee

any fee real Property (with respect to any fee real Property acquired after the
Closing Date), execute, acknowledge and deliver to the Administrative Agent a
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
such Loan Party subsequent to the Closing Date, together with evidence
satisfactory to the Administrative Agent and its counsel that the Mortgage
creates a valid, first priority Lien on the fee estate, in favor of the
Administrative Agent for the benefit of the Administrative Agent and the
Lenders, a mortgagee policy of title insurance insuring the Administrative
Agent's first priority Lien status created by each such Mortgage, a current
survey certified to the Administrative Agent and the Lenders, an appraisal
complying with all applicable regulatory requirements, and an environmental
survey acceptable to the Administrative Agent, all of which shall be in form and
substance reasonably satisfactory to the Administrative Agent; provided,
however, that, with respect to any particular parcel of real Property having a
fair market value (inclusive of fixtures) of $250,000 or less, a mortgagee
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 as to which an

of the Borrower and its Operating Subsidiaries (a) has entered into, or will
timely enter into, such long-distance carrier and interconnection agreements (or
agreements with third parties, such as the Sprint Agreements, which provide such
long-distance carrier and interconnection rights indirectly) as are, at any time
of determination, then necessary to the conduct of its business in accordance
with the Business Plan and (b) will conduct its business generally in accordance
with the Business Plan, in each case except to the extent that the failure to do
so could not reasonably be expected to cause a Material Adverse Effect. Each of
the Loan Parties will conduct its business in an orderly and efficient manner in
accordance with good business practices and the Business Plan.

         Section 8.3 Maintenance of Properties and Permits. Each of the Loan

none of the Loan Parties shall be required to pay or discharge any tax, levy,
assessment or governmental charge, or claim for labor, material or supplies,
whose amount, applicability or validity is being contested in good faith by
appropriate proceedings being diligently pursued and for which adequate reserves

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

CREDIT AGREEMENT - Page 72

         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 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

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

                  (iv) Worker's Compensation Insurance. Worker's compensation

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

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"

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
Administrative Agent) to comply with this Section 8.6. The Administrative Agent
or its representatives may, at any time and from time to time at the Borrower's

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

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

         (b) Termination of Commitments. Terminate each of the Commitments
without notice to the Borrower or any other Loan Party;

         (c) Judgment. Reduce any claim to judgment;

         (d) Foreclosure. Foreclose or otherwise enforce any Lien granted to the
Administrative Agent for the benefit of the Administrative Agent and the Lenders
to secure payment and performance of the Obligations in accordance with the
terms of the Loan Documents; or

         (e) Rights. Exercise any and all rights and remedies afforded by the
laws of the State of New York or any other jurisdiction, by any of the Loan
Documents, by equity or otherwise;

provided, however, that upon the occurrence of an Event of Default under Section
11.1(e) or Section 11.1(f), the Commitments of all of the Lenders shall
immediately and automatically terminate, and the outstanding principal of and
accrued and unpaid interest on the Loans and all other amounts payable by the
Borrower or any other Loan Party under the Loan Documents shall thereupon become
immediately and automatically due and payable, without notice, demand,
presentment, notice of dishonor, notice of acceleration, notice of intent to
accelerate, protest or other formalities of any kind, all of which are hereby
expressly waived by the Borrower and the other Loan Parties.

         Section 11.3 Performance by the Administrative Agent, etc.. If the
Borrower or any other Loan Party shall fail to perform any covenant or agreement
in accordance with the terms of the Loan Documents, the Administrative Agent may
perform or attempt to perform, or may cause any Lender


CREDIT AGREEMENT - Page 90
<PAGE>   98

(with the consent of such Lender) to perform or attempt to perform, such
covenant or agreement on behalf of the Borrower or such other Loan Party (as
applicable). In such event, the Borrower shall, at the request of the
Administrative Agent, promptly pay any amount expended by the Administrative
Agent or the Lenders in connection with such performance or attempted
performance to the Administrative Agent at its Principal Office, together with
interest thereon at the applicable Default Rate from and including the date of
such expenditure to but excluding the date such expenditure is paid in full.
Notwithstanding the foregoing, it is expressly agreed that neither the
Administrative Agent nor any Lender shall have any liability or responsibility
for the performance of any obligation of the Borrower or any other Loan Party or
any other Person under this Agreement or any of the other Loan Documents.

                                   ARTICLE 12

                            The Administrative Agent

         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 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


CREDIT AGREEMENT - Page 91
<PAGE>   99

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 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


CREDIT AGREEMENT - Page 92
<PAGE>   100

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 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


CREDIT AGREEMENT - Page 93
<PAGE>   101

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
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,


CREDIT AGREEMENT - Page 94
<PAGE>   102

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) 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


CREDIT AGREEMENT - Page 95
<PAGE>   103

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.

         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.


CREDIT AGREEMENT - Page 96
<PAGE>   104

         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 (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


CREDIT AGREEMENT - Page 97
<PAGE>   105

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.

         (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


CREDIT AGREEMENT - Page 98
<PAGE>   106

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 "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


CREDIT AGREEMENT - Page 99
<PAGE>   107

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 Register shall be available for inspection by the
Borrower and any Lender at any reasonable time upon reasonable prior notice.

         (i) The Loan Parties will not become a party to any loan agreement,
credit agreement or similar agreement which restricts or prohibits the right or
ability of any lender which is a party thereto to become a Lender under this
Agreement.

         (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 by the
Administrative Agent or its advisors, including, without limitation, providing
information to and responding to inquiries from prospective Lenders with respect
to the business, operations, Business Plan, results and other matters relating
to the business of Holdings, the Borrower and the other Loan Parties.

         Section 13.9 Survival. All representations and warranties made or
deemed made in this Agreement or any other Loan Document or in any document,
statement or certificate furnished in connection with this Agreement shall
survive the execution and delivery of this Agreement and the other Loan
Documents and the making of the Loans, and no investigation by the
Administrative Agent or any Lender or any closing shall affect the
representations and warranties or the right of the Administrative Agent or any
Lender to rely upon them. Without prejudice to the survival of any


CREDIT AGREEMENT - Page 100
<PAGE>   108

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 AMONG THE
PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, TERM SHEETS,
AGREEMENTS, REPRESENTATIONS AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL,
RELATING TO THE SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED OR VARIED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS
OF THE PARTIES HERETO. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN OR AMONG
(A) ANY ONE OR MORE OF THE LOAN PARTIES AND (B) ANY ONE OR MORE OF THE
ADMINISTRATIVE AGENT AND/OR THE LENDERS.

         Section 13.11 Amendments. No amendment or waiver of any provision of
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) reduce the principal of,
or interest on, the Loans or any fees or other amounts payable hereunder; (c)
postpone any date fixed for any payment (including, without limitation, any
mandatory prepayment) of principal of, or interest on, the Loans or any fees or
other amounts payable hereunder; (d) change the Commitment Percentages or the
aggregate unpaid principal amount of the Loans or the number or interests of the
Lenders which shall be required for the Lenders or any of them to take any
action under this Agreement; (e) change any provision contained in Section 3.2,
3.3 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 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
for in this Agreement and the other Loan Documents to which the Borrower,

mailed notice, upon receipt, in each case given or addressed as aforesaid;

DOCUMENTS, THIS AGREEMENT, THE NOTES AND THE OTHER LOAN DOCUMENTS SHALL BE

PROCEEDING BY THE MAILING OF COPIES OF SUCH PROCESS TO SUCH PERSON AT ITS

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

efforts to keep any information delivered or made available by the Borrower to
it which is clearly indicated to be confidential information, confidential from

quotation system upon which the Company's securities are listed or quoted, or
any other applicable law, rule or restriction (collectively, "applicable law"),
to the extent that any such restrictions are no longer required by applicable
law, the Committee shall have the sole discretion and authority to grant Awards
that are not subject to such mandated restrictions and/or to waive any such
mandated restrictions with respect to outstanding Awards.

                                    ARTICLE 4
                                   ELIGIBILITY

         Any Employee (including an Employee who is also a director or an
officer), Outside Director, or consultant of the Company whose judgment,
initiative, and efforts contributed or may be expected to contribute to the
successful performance of the Company is eligible to participate in the Plan;
provided that only Employees shall be eligible to receive Incentive Stock
Options. The Committee, upon its own action, may grant, but shall not be
required to grant, an Award to any Employee, Outside Director, or consultant of
the Company or any Subsidiary. Awards may be granted by the Committee at any
time and from time to time to new Participants, or to then

<PAGE>   7

Participants, or to a greater or lesser number of Participants, and may include
or exclude previous Participants, as the Committee shall determine. Except as
required by this Plan, Awards granted at different times need not contain
similar provisions. The Committee's determinations under the Plan (including
without limitation determinations of which Employees, Outside Directors, or
consultants, if any, are to receive Awards, the form, amount and timing of such
Awards, the terms and provisions of such Awards and the agreements evidencing
same) need not be uniform and may be made by it selectively among Participants
who receive, or are eligible to receive, Awards under the Plan.

                                    ARTICLE 5
                             SHARES SUBJECT TO PLAN

         Subject to adjustment as provided in Articles 13 and 14, the maximum
number of shares of Common Stock that may be delivered pursuant to Awards
granted under the Plan is seven million (7,000,000) shares; plus (a) shares of
Common Stock previously subject to Awards which are forfeited, terminated,
settled in cash in lieu of Common Stock, or exchanged for Awards that do not
involve Common Stock, or expired unexercised; plus (b) any shares of Common
Stock surrendered to the Company in payment of the exercise price of options
issued under the Plan; provided, however, that in no event shall the number of
shares of Common Stock subject to Incentive Stock Options exceed, in the
aggregate, seven million (7,000,000) shares of Common Stock plus shares subject
to Incentive Stock Options which are forfeited or terminated, or expire
unexercised.

         Shares to be issued may be made available from authorized but unissued
Common Stock, Common Stock held by the Company in its treasury, or Common Stock
purchased by the Company on the open market or otherwise. During the term of
this Plan, the Company will at all times reserve and keep available the number
of shares of Common Stock that shall be sufficient to satisfy the requirements
of this Plan.

                                    ARTICLE 6
                                 GRANT OF AWARDS

         6.1 IN GENERAL. The grant of an Award shall be authorized by the
Committee and shall be evidenced by an Award Agreement setting forth the
Incentive or Incentives being granted, the total number of shares of Common
Stock subject to the Incentive(s), the Option Price (if applicable), the Award
Period, the Date of Grant, and such other terms, provisions, limitations, and
performance objectives, as are approved by the Committee, but not inconsistent
with the Plan. The Company shall execute an Award Agreement with a Participant
after the Committee approves the issuance of an Award. Any Award granted
pursuant to this Plan must be granted within ten (10) years of the date of
adoption of this Plan. The Plan shall be submitted to the


                                        7
<PAGE>   8

Company's stockholders for approval; however, the Committee may grant Awards
under the Plan prior to the time of stockholder approval. Any such Award granted
prior to such stockholder approval shall be made subject to such stockholder
approval. The grant of an Award to a Participant shall not be deemed either to
entitle the Participant to, or to disqualify the Participant from, receipt of
any other Award under the Plan.

         If the Committee establishes a purchase price for an Award, the
Participant must accept such Award within a period of thirty (30) days (or such
shorter period as the Committee may specify) after the Date of Grant by
executing the applicable Award Agreement and paying such purchase price.

         6.2 MAXIMUM ISO GRANTS. The Committee may not grant Incentive Stock
Options under the Plan to any Employee which would permit the aggregate Fair
Market Value (determined on the Date of Grant) of the Common Stock with respect
to which Incentive Stock Options (under this and any other plan of the Company
and its Subsidiaries) are exercisable for the first time by such Employee during
any calendar year to exceed $100,000. To the extent any Stock Option granted
under this Plan which is designated as an Incentive Stock Option exceeds this
limit or otherwise fails to qualify as an Incentive Stock Option, such Stock
Option (or any such portion thereof) shall be a Non-qualified Stock Option.

         6.3 MAXIMUM INDIVIDUAL GRANTS. No Participant may receive during any
fiscal year of the Company Awards covering an aggregate of more than two million
(2,000,000) shares of Common Stock.

         6.4 RESTRICTED STOCK. If Restricted Stock is granted to a Participant
under an Award, the Committee shall set forth in the related Award Agreement:
(i) the number of shares of Common Stock awarded, (ii) the price, if any, to be
paid by the Participant for such Restricted Stock, (iii) the time or times
within which such Award may be subject to forfeiture, (iv) specified performance
goals of the Company, a Subsidiary, any division thereof or any group of
Employees of the Company, or other criteria, which the Committee determines must
be met in order to remove any restrictions (including vesting) on such Award,
and (v) all other terms, limitations, restrictions, and conditions of the
Restricted Stock, which shall be consistent with this Plan. The provisions of
Restricted Stock need not be the same with respect to each Participant.

         (a) LEGEND ON SHARES. Each Participant who is awarded Restricted Stock
shall be issued a stock certificate or certificates in respect of such shares of
Common Stock. Such certificate(s) shall be registered in the name of the
Participant, and shall bear an appropriate legend referring to the terms,
conditions, and

                                        8
<PAGE>   9

restrictions applicable to such Restricted Stock, substantially as provided in
Section 17.9 of the Plan.

         The Committee may require that the stock certificates evidencing shares
of Restricted Stock be held in custody by the Company until the restrictions
thereon shall have lapsed, and that the Participant deliver to the Committee a
stock power or stock powers, endorsed in blank, relating to the shares of
Restricted Stock.

         (b) RESTRICTIONS AND CONDITIONS. Shares of Restricted Stock shall be
subject to the following restrictions and conditions:

                  (i) Subject to the other provisions of this Plan and the terms
         of the particular Award Agreements, during such period as may be
         determined by the Committee commencing on the Date of Grant (the
         "Restriction Period"), the Participant shall not be permitted to sell,
         transfer, pledge or assign shares of Restricted Stock. Except for these
         limitations, the Committee may in its sole discretion, remove any or
         all of the restrictions on such Restricted Stock whenever it may
         determine that, by reason of changes in applicable laws or other
         changes in circumstances arising after the date of the Award, such
         action is appropriate.

                  (ii) Except as provided in sub-paragraph (i) above, the
         Participant shall have, with respect to his or her Restricted Stock,
         all of the rights of a stockholder of the Company, including the right
         to vote the shares, and the right to receive any dividends thereon.
         Certificates for shares of Common Stock free of restriction under this
         Plan shall be delivered to the Participant promptly after, and only
         after, the Restriction Period shall expire without forfeiture in
         respect of such shares of Common Stock. Certificates for the shares of
         Common Stock forfeited under the provisions of the Plan and the
         applicable Award Agreement shall be promptly returned to the Company by
         the forfeiting Participant. Each Award Agreement shall require that (x)
         each Participant, by his or her acceptance of Restricted Stock, shall
         irrevocably grant to the Company a power of attorney to transfer any
         shares so forfeited to the Company and agrees to execute any documents
         requested by the Company in connection with such forfeiture and
         transfer, and (y) such provisions regarding returns and transfers of
         stock certificates with respect to forfeited shares of Common Stock
         shall be specifically performable by the Company in a court of equity
         or law.

                  (iii) The Restriction Period of Restricted Stock shall
         commence on the Date of Grant and, subject to Article 14 of the Plan,
         unless otherwise established by the Committee in the Award Agreement
         setting forth the terms of the Restricted Stock, shall expire upon
         satisfaction of the conditions set forth in the Award Agreement; such
         conditions may provide for vesting based on (i)

                                        9
<PAGE>   10

         length of continuous service, (ii) achievement of specific business
         objectives, (iii) increases in specified indices, (iv) attainment of
         specified growth rates, or (v) other comparable measurements of Company
         performance, as may be determined by the Committee in its sole
         discretion.

                  (iv) Subject to the provisions of the particular Award
         Agreement, upon Termination of Service for any reason during the
         Restriction Period, the nonvested shares of Restricted Stock shall be
         forfeited by the Participant. In the event a Participant has paid any
         consideration to the Company for such forfeited Restricted Stock, the
         Company shall, as soon as practicable after the event causing
         forfeiture (but in any event within five (5) business days), pay to the
         Participant, in cash, an amount equal to the total consideration paid
         by the Participant for such forfeited shares. Upon any forfeiture, all
         rights of a Participant with respect to the forfeited shares of the
         Restricted Stock shall cease and terminate, without any further
         obligation on the part of the Company.

         6.5 SAR. An SAR shall entitle the Participant at his election to
surrender to the Company the SAR, or portion thereof, as the Participant shall
choose, and to receive from the Company in exchange therefor cash in an amount
equal to the excess (if any) of the Fair Market Value (as of the date of the
exercise of the SAR) per share over the SAR Price per share specified in such
SAR, multiplied by the total number of shares of the SAR being surrendered. In
the discretion of the Committee, the Company may satisfy its obligation upon
exercise of a SAR by the distribution of that number of shares of Common Stock
having an aggregate Fair Market Value (as of the date of the exercise of the
SAR) equal to the amount of cash otherwise payable to the Participant, with a
cash settlement to be made for any fractional share interests, or the Company
may settle such obligation in part with shares of Common Stock and in part with
cash.

         6.6 TANDEM AWARDS. The Committee may grant two or more Incentives in
one Award in the form of a "tandem award," so that the right of the Participant
to exercise one Incentive shall be canceled if, and to the extent, the other
Incentive is exercised. For example, if a Stock Option and a SAR are issued in a
tandem Award, and the Participant exercises the SAR with respect to 100 shares
of Common Stock, the right of the Participant to exercise the related Stock
Option shall be canceled to the extent of 100 shares of Common Stock.

                             OPTION PRICE; SAR PRICE

         The Option Price for any share of Common Stock which may be purchased
under a Non-qualified Stock Option and the SAR Price for any share of Common
Stock subject to a SAR may be less than, equal to, or greater than the Fair
Market Value of the share on the Date of Grant. The Option Price for any share
of Common Stock which may be purchased under an Incentive Stock Option must be
at least equal to the Fair Market Value of the share on the Date of Grant; if an
Incentive Stock Option is granted to an Employee who owns or is deemed to own
(by reason of the attribution rules of Section 424(d) of the Code) more than ten
percent (10%) of the combined voting power of all classes of stock of the
Company (or any parent or Subsidiary), the Option Price shall be at least 110%
of the Fair Market Value of the Common Stock on the Date of Grant.

                                    ARTICLE 8
                              AWARD PERIOD; VESTING

         8.1 AWARD PERIOD. Subject to the other provisions of this Plan, the
Committee may, in its discretion, provide that an Incentive may not be exercised
in whole or in part for any period or periods of time or beyond any date
specified in the Award Agreement. Except as provided in the Award Agreement, an
Incentive may be exercised in whole or in part at any time during its term. The
Award Period for an Incentive shall be reduced or terminated upon Termination of
Service in accordance with this Article 8 and Article 9. No Incentive granted
under the Plan may be exercised at any time after the end of its Award Period.
No portion of any Incentive may be exercised after the expiration of ten (10)
years from its Date of Grant. However, if an Employee owns or is deemed to own
(by reason of the attribution rules of Section 424(d) of the Code) more than ten
percent (10%) of the combined voting power of all classes of stock of the
Company (or any parent or Subsidiary) and an Incentive Stock Option is granted
to such Employee, the term of such Incentive Stock Option (to the extent
required by the Code at the time of grant) shall be no more than five (5) years
from the Date of Grant.

         8.2 VESTING. The Committee, in its sole discretion, may determine that
an Incentive will be immediately exercisable, in whole or in part, or that all
or any portion may not be exercised until a date, or dates, subsequent to its
Date of Grant, or until the occurrence of one or more specified events, subject
in any case to the terms of the Plan. If the Committee imposes conditions upon
exercise, then subsequent to the Date of Grant, the Committee may, in its sole
discretion, accelerate the date on which all or any portion of the Incentive may
be exercised.

                                    ARTICLE 9
                             TERMINATION OF SERVICE

         In the event of Termination of Service of a Participant, an Incentive
may only be exercised as determined by the Committee and provided in the Award
Agreement.

                                   ARTICLE 10
                              EXERCISE OF INCENTIVE

         10.1 IN GENERAL. A vested Incentive may be exercised during its Award
Period, subject to limitations and restrictions set forth in the Award Agreement
and in Article 9. A vested Incentive may be exercised at such times and in such
amounts as provided in this Plan and the applicable Award Agreement, subject to
the terms, conditions, and restrictions of the Plan.

         In no event may an Incentive be exercised or shares of Common Stock be
issued pursuant to an Award if a necessary listing or quotation of the shares of
Common Stock on a stock exchange or inter-dealer quotation system or any
registration under state or federal securities laws required under the
circumstances has not been accomplished. No Incentive may be exercised for a
fractional share of Common Stock. The granting of an Incentive shall impose no
obligation upon the Participant to exercise that Incentive.

         (a) STOCK OPTIONS. Subject to such administrative regulations as the
Committee may from time to time adopt, a Stock Option may be exercised by the
delivery of written notice to the Committee setting forth the number of shares
of Common Stock with respect to which the Stock Option is to be exercised and
the date of exercise thereof (the "Exercise Date") which shall be at least three
(3) days after giving such notice unless an earlier time shall have been
mutually agreed upon. On the Exercise Date, the Participant shall deliver to the
Company consideration with a value equal to the total Option Price of the shares
to be purchased, payable as follows: (a) cash, check, bank draft, or money order
payable to the order of the Company, (b) Common Stock (including Restricted
Stock) owned by the Participant on the Exercise Date, valued at its Fair Market
Value on the Exercise Date, (c) by delivery (including by FAX) to the Company or
its designated agent of an executed irrevocable option exercise form together
with irrevocable instructions from the Participant to a broker or dealer,
reasonably acceptable to the Company, to sell certain of the shares of Common
Stock purchased upon exercise of the Stock Option or to pledge such shares as
collateral for a loan and promptly deliver to the Company the amount of sale or
loan proceeds necessary to pay such purchase price, and/or (d) in any other form
of valid consideration that is acceptable to the Committee in its sole
discretion. In the event that shares of Restricted Stock are tendered as
consideration for the exercise of a Stock Option, a number of shares of Common
Stock issued upon the exercise of the Stock

                                       12
<PAGE>   13
Option equal to the number of shares of Restricted Stock used as consideration
therefor shall be subject to the same restrictions and provisions as the
Restricted Stock so submitted.


         Upon payment of all amounts due from the Participant, the Company shall
cause certificates for the Common Stock then being purchased to be delivered as
directed by the Participant (or the person exercising the Participant's Stock
Option in the event of his death) at its principal business office promptly
after the Exercise Date; provided that if the Participant has exercised an
Incentive Stock Option, the Company may at its option retain physical possession
of the certificate evidencing the shares acquired upon exercise until the
expiration of the holding periods described in Section 422(a)(1) of the Code.
The obligation of the Company to deliver shares of Common Stock shall, however,
be subject to the condition that if at any time the Committee shall determine in
its discretion that the listing, registration, or qualification of the Stock
Option or the Common Stock upon any securities exchange or inter-dealer
quotation system or under any state or federal law, or the consent or approval
of any governmental regulatory body, is necessary as a condition of, or in
connection with, the Stock Option or the issuance or purchase of shares of
Common Stock thereunder, the Stock Option may not be exercised in whole or in
part unless such listing, registration, qualification, consent, or approval
shall have been effected or obtained free of any conditions not reasonably
acceptable to the Committee.


         If the Participant fails to pay for any of the Common Stock specified
in such notice or fails to accept delivery thereof, the Participant's right to
purchase such Common Stock may be terminated by the Company.

         (b) SARS. Subject to the conditions of this Section 10.1(b) and such
administrative regulations as the Committee may from time to time adopt, a SAR
may be exercised by the delivery (including by FAX) of written notice to the
Committee setting forth the number of shares of Common Stock with respect to
which the SAR is to be exercised and the date of exercise thereof (the "Exercise
Date") which shall be at least three (3) days after giving such notice unless an
earlier time shall have been mutually agreed upon. On the Exercise Date, the
Participant shall receive from the Company in exchange therefor cash in an
amount equal to the excess (if any) of the Fair Market Value (as of the date of
the exercise of the SAR) per share of Common Stock over the SAR Price per share
specified in such SAR, multiplied by the total number of shares of Common Stock
of the SAR being surrendered. In the discretion of the Committee, the Company
may satisfy its obligation upon exercise of a SAR by the distribution of that
number of shares of Common Stock having an aggregate Fair Market Value (as of
the date of the exercise of the SAR) equal to the amount of cash otherwise
payable to the Participant, with a cash settlement to be made for any fractional
share interests, or the Company may settle such obligation in part with shares
of Common Stock and in part with cash.

         10.2 DISQUALIFYING DISPOSITION OF ISO. If shares of Common Stock
acquired upon exercise of an Incentive Stock Option are disposed of by a
Participant prior to the expiration of either two (2) years from the Date of
Grant of such Stock Option or one (1) year from the transfer of shares of Common
Stock to the Participant pursuant to the exercise of such Stock Option, or in
any other disqualifying disposition within the meaning of Section 422 of the
Code, such Participant shall notify the Company in writing of the date and terms
of such disposition. A disqualifying disposition by a Participant shall not
affect the status of any other Stock Option granted under the Plan as an
Incentive Stock Option within the meaning of Section 422 of the Code.

                                   ARTICLE 11
                           AMENDMENT OR DISCONTINUANCE

         Subject to the limitations set forth in this Article 11, the Board may
at any time and from time to time, without the consent of the Participants,
alter, amend, revise, suspend, or discontinue the Plan in whole or in part;
provided, however, that no amendment which requires stockholder approval in
order for the Plan and Incentives awarded under the Plan to continue to comply
with Sections 162(m), 421, and 422 of the Code, including any successors to such
Sections, shall be effective unless such amendment shall be approved by the
requisite vote of the stockholders of the Company entitled to vote thereon. Any
such amendment shall, to the extent deemed necessary or advisable by the
committee, be applicable to any outstanding Incentives theretofore granted under
the Plan, notwithstanding any contrary provisions contained in any stock option
agreement. In the event of any such amendment to the Plan, the holder of any
Incentive outstanding under the Plan shall, upon request of the Committee and as
a condition to the exercisability thereof, execute a conforming amendment in the
form prescribed by the Committee to any Award Agreement relating thereto.
Notwithstanding anything contained in this Plan to the contrary, unless required
by law, no action contemplated or permitted by this Article 11 shall adversely
affect any rights of Participants or obligations of the Company to Participants
with respect to any Incentive theretofore granted under the Plan without the
consent of the affected Participant.

                                   ARTICLE 12
                                      TERM

         The Plan shall be effective from the date that this Plan is approved by
the Board. Unless sooner terminated by action of the Board, the Plan will
terminate on November 11, 2009, but Incentives granted before that date will
continue to be effective in accordance with their terms and conditions.

                               CAPITAL ADJUSTMENTS

         If at any time while the Plan is in effect, or Incentives are
outstanding, there shall be any increase or decrease in the number of issued and
outstanding shares of Common Stock resulting from (1) the declaration or payment
of a stock dividend, (2) any recapitalization resulting in a stock split-up,
combination, or exchange of shares of Common Stock, or (3) other increase or
decrease in such shares of Common Stock effected without receipt of
consideration by the Company, then and in such event:

                  (i) An appropriate adjustment shall be made in the maximum
         number of shares of Common Stock then subject to being awarded under
         the Plan and in the maximum number of shares of Common Stock that may
         be awarded to a Participant to the end that the same proportion of the
         Company's issued and outstanding shares of Common Stock shall continue
         to be subject to being so awarded.

                  (ii) Appropriate adjustments shall be made in the number of
         shares of Common Stock and the Option Price thereof then subject to
         purchase pursuant to each such Stock Option previously granted and
         unexercised, to the end that the same proportion of the Company's
         issued and outstanding shares of Common Stock in each such instance
         shall remain subject to purchase at the same aggregate Option Price.

                  (iii) Appropriate adjustments shall be made in the number of
         SARs and the SAR Price thereof then subject to exercise pursuant to
         each such SAR previously granted and unexercised, to the end that the
         same proportion of the Company's issued and outstanding shares of
         Common Stock in each instance shall remain subject to exercise at the
         same aggregate SAR Price.

                  (iv) Appropriate adjustments shall be made in the number of
         outstanding shares of Restricted Stock with respect to which
         restrictions have not yet lapsed prior to any such change.

         Except as otherwise expressly provided herein, the issuance by the
Company of shares of its capital stock of any class, or securities convertible
into shares of capital stock of any class, either in connection with direct sale
or upon the exercise of rights or warrants to subscribe therefor, or upon
conversion of shares or obligations of the Company convertible into such shares
or other securities, shall not affect, and no adjustment by reason thereof shall
be made with respect to (i) the number of or Option Price of shares of Common
Stock then subject to outstanding Stock Options granted under the Plan, (ii) the
number of or SAR Price or SARs then subject to outstanding

                                       15
<PAGE>   16

SARs granted under the Plan, or (iii) the number of outstanding shares of
Restricted Stock.

         Upon the occurrence of each event requiring an adjustment with respect
to any Incentive, the Company shall mail to each affected Participant its
computation of such adjustment which shall be conclusive and shall be binding
upon each such Participant.

                          RECAPITALIZATION, MERGER AND
                        CONSOLIDATION; CHANGE IN CONTROL

                  (a) The existence of this Plan and Incentives granted
         hereunder shall not affect in any way the right or power of the Company
         or its stockholders to make or authorize any or all adjustments,
         recapitalizations, reorganizations, or other changes in the Company's
         capital structure and its business, or any merger or consolidation of
         the Company, or any issue of bonds, debentures, preferred or preference
         stocks ranking prior to or otherwise affecting the Common Stock or the
         rights thereof (or any rights, options, or warrants to purchase same),
         or the dissolution or liquidation of the Company, or any sale or
         transfer of all or any part of its assets or business, or any other
         corporate act or proceeding, whether of a similar character or
         otherwise.

                  (b) Subject to any required action by the stockholders, if the
         Company shall be the surviving or resulting corporation in any merger,
         consolidation or share exchange, any Incentive granted hereunder shall
         pertain to and apply to the securities or rights (including cash,
         property, or assets) to which a holder of the number of shares of
         Common Stock subject to the Incentive would have been entitled.

                  (c) In the event of any merger, consolidation or share
         exchange pursuant to which the Company is not the surviving or
         resulting corporation, there shall be substituted for each share of
         Common Stock subject to the unexercised portions of such outstanding
         Incentives, that number of shares of each class of stock or other
         securities or that amount of cash, property, or assets of the
         surviving, resulting or consolidated company which were distributed or
         distributable to the stockholders of the Company in respect to each
         share of Common Stock held by them, such outstanding Incentives to be
         thereafter exercisable for such stock, securities, cash, or property in
         accordance with their terms. Notwithstanding the foregoing, however,
         all such Incentives may be canceled by the Company as of the effective
         date of any such reorganization, merger, consolidation, share exchange
         or any dissolution or liquidation of the Company by giving notice to
         each holder thereof or his personal representative of its intention to
         do so and by permitting the purchase during the thirty (30)

         day period next preceding such effective date of all of the shares of
         Common Stock subject to such outstanding Incentives.

                  (d) In the event of a Change of Control, then, notwithstanding
         any other provision in this Plan to the contrary, all unmatured
         installments of Incentives outstanding shall thereupon automatically be
         accelerated and exercisable in full and all Restriction Periods
         applicable to Awards of Restricted Stock shall automatically expire.
         The determination of the Committee that any of the foregoing conditions
         has been met shall be binding and conclusive on all parties.

                                   ARTICLE 15
                           LIQUIDATION OR DISSOLUTION

         In case the Company shall, at any time while any Incentive under this
Plan shall be in force and remain unexpired, (i) sell all or substantially all
of its property, or (ii) dissolve, liquidate, or wind up its affairs, then each
Participant shall be thereafter entitled to receive, in lieu of each share of
Common Stock of the Company which such Participant would have been entitled to
receive under the Incentive, the same kind and amount of any securities or
assets as may be issuable, distributable, or payable upon any such sale,
dissolution, liquidation, or winding up with respect to each share of Common
Stock of the Company. If the Company shall, at any time prior to the expiration
of any Incentive, make any partial distribution of its assets, in the nature of
a partial liquidation, whether payable in cash or in kind (but excluding the
distribution of a cash dividend payable out of earned surplus and designated as
such) then in such event the Option Prices or SAR Prices then in effect with
respect to each Stock Option or SAR shall be reduced, on the payment date of
such distribution, in proportion to the percentage reduction in the tangible
book value of the shares of the Company's Common Stock (determined in accordance
with generally accepted accounting principles) resulting by reason of such
distribution.

                                   ARTICLE 16
                         INCENTIVES IN SUBSTITUTION FOR
                      INCENTIVES GRANTED BY OTHER ENTITIES

         Incentives may be granted under the Plan from time to time in
substitution for similar instruments held by employees or directors of a
corporation, partnership, or limited liability company who become or are about
to become management Employees or Outside Directors of the Company or any
Subsidiary as a result of a merger or consolidation of the employing corporation
with the Company, the acquisition by the Company of equity of the employing
entity, or any other similar transaction pursuant to which the Company becomes
the successor employer. The terms and conditions of the substitute Incentives so
granted may vary from the terms and conditions set forth

                                       17
<PAGE>   18

in this Plan to such extent as the Board at the time of grant may deem
appropriate to conform, in whole or in part, to the provisions of the Incentives
in substitution for which they are granted.

                                   ARTICLE 17
                            MISCELLANEOUS PROVISIONS

         17.1 INVESTMENT INTENT. The Company may require that there be presented
to and filed with it by any Participant under the Plan, such evidence as it may
deem necessary to establish that the Incentives granted or the shares of Common
Stock to be purchased or transferred are being acquired for investment and not
with a view to their distribution.

         17.2 NO RIGHT TO CONTINUED EMPLOYMENT.  Neither the Plan nor any
Incentive granted under the Plan shall confer upon any Participant any right
with respect to continuance of employment by the Company or any Subsidiary.

         17.3 INDEMNIFICATION OF BOARD AND COMMITTEE. No member of the Board or
the Committee, nor any officer or Employee of the Company acting on behalf of
the Board or the Committee, shall be personally liable for any action,
determination, or interpretation taken or made in good faith with respect to the
Plan, and all members of the Board or the Committee and each and any officer or
employee of the Company acting on their behalf shall, to the extent permitted by
law, be fully indemnified and protected by the Company in respect of any such
action, determination, or interpretation.

         17.4 EFFECT OF THE PLAN. Neither the adoption of this Plan nor any
action of the Board or the Committee shall be deemed to give any person any
right to be granted an Award or any other rights except as may be evidenced by
an Award Agreement, or any amendment thereto, duly authorized by the Committee
and executed on behalf of the Company, and then only to the extent and upon the
terms and conditions expressly set forth therein.

         17.5 COMPLIANCE WITH OTHER LAWS AND REGULATIONS. Notwithstanding
anything contained herein to the contrary, the Company shall not be required to
sell or issue shares of Common Stock under any Incentive if the issuance thereof
would constitute a violation by the Participant or the Company of any provisions
of any law or regulation of any governmental authority or any national
securities exchange or inter-dealer quotation system or other forum in which
shares of Common Stock are quoted or traded (including without limitation
Section 16 of the 1934 Act and Section 162(m) of the Code); and, as a condition
of any sale or issuance of shares of Common Stock under an Incentive, the
Committee may require such agreements or undertakings, if any, as the Committee
may deem necessary or advisable to assure

                                       18
<PAGE>   19
compliance with any such law or regulation. The Plan, the grant and exercise of
Incentives hereunder, and the obligation of the Company to sell and deliver
shares of Common Stock, shall be subject to all applicable federal and state
laws, rules and regulations and to such approvals by any government or
regulatory agency as may be required.

         17.6 TAX REQUIREMENTS. The Company shall have the right to deduct from
all amounts hereunder paid in cash or other form, any Federal, state, or local
taxes required by law to be withheld with respect to such payments. The
Participant receiving shares of Common Stock issued under the Plan shall be
required to pay the Company the amount of any taxes which the Company is
required to withhold with respect to such shares of Common Stock.
Notwithstanding the foregoing, in the event of an assignment of a Non-qualified
Stock Option or SAR pursuant to Section 17.7, the Participant who assigns the
Non-qualified Stock Option or SAR shall remain subject to withholding taxes upon
exercise of the Non-qualified Stock Option or SAR by the transferee to the
extent required by the Code or the rules and regulations promulgated thereunder.
Such payments shall be required to be made prior to the delivery of any
certificate representing such shares of Common Stock. Such payment may be made
in cash, by check, or through the delivery of shares of Common Stock owned by
the Participant but not acquired from the Company within six (6) months prior to
such payment (which may be effected by the actual delivery of shares of Common
Stock by the Participant or by the Company's withholding a number of shares to
be issued upon the exercise of a Stock Option, if applicable), which shares have
an aggregate Fair Market Value equal to the required minimum withholding
payment, or any combination thereof.

         17.7 ASSIGNABILITY. Incentive Stock Options may not be transferred or
assigned other than by will or the laws of descent and distribution and may be
exercised during the lifetime of the Participant only by the Participant or the
Participant's legally authorized representative, and each Award Agreement in
respect of an Incentive Stock Option shall so provide. The designation by a
Participant of a beneficiary will not constitute a transfer of the Stock Option.
The Committee may waive or modify any limitation contained in the preceding
sentences of this Section 17.7 that is not required for compliance with Section
422 of the Code.

         The Committee may, in its discretion, authorize all or a portion of a
Non-qualified Stock Option or SAR to be granted to a Participant to be on terms
which permit transfer by such Participant to (i) the spouse, children or
grandchildren of the Participant ("Immediate Family Members"), (ii) a trust or
trusts for the exclusive benefit of such Immediate Family Members, (iii) a
partnership in which such Immediate Family Members are the only partners, (iv)
an entity exempt from federal income tax pursuant to Section 501(c)(3) of the
Code or any successor provision, or (v) a split interest trust or pooled income
fund described in Section 2522(c)(2) of the Code

                                       19
<PAGE>   20

or any successor provision, provided that (x) there shall be no consideration
for any such transfer, (y) the Award Agreement pursuant to which such
Non-qualified Stock Option or SAR is granted must be approved by the Committee
and must expressly provide for transferability in a manner consistent with this
Section, and (z) subsequent transfers of transferred Non-qualified Stock Options
or SARs shall be prohibited except those by will or the laws of descent and
distribution. In addition, the Committee may, in its discretion, authorize all
or a portion of a Non-qualified Stock Option or SAR to be granted to an Outside
Director to be on terms which permit transfer by such Outside Director of a
portion or all of such an Award to his or her employer, provided that (x) the
Award Agreement pursuant to which such Non- qualified Stock Option or SAR is
granted must be approved by the Committee and must expressly provide for
transferability in a manner consistent with this Section, and (y) unless
specifically authorized in the Award Agreement, subsequent transfers of
transferred Non-qualified Stock Options or SARs shall be prohibited except those
by will or the laws of descent and distribution.

         Following any transfer, any such Non-qualified Stock Option and SAR
shall continue to be subject to the same terms and conditions as were applicable
immediately prior to transfer, provided that for purposes of Articles 10, 11,
13, 15 and 17 hereof the term "Participant" shall be deemed to include the
transferee. The events of Termination of Service shall continue to be applied
with respect to the original Participant, following which the Non-qualified
Stock Options and SARs shall be exercisable by the transferee only to the extent
and for the periods specified in the Award Agreement. The Committee and the
Company shall have no obligation to inform any transferee of a Non-qualified
Stock Option or SAR of any expiration, termination, lapse or acceleration of
such Option. The Company shall have no obligation to register with any federal
or state securities commission or agency any Common Stock issuable or issued
under a Non-qualified Stock Option or SAR that has been transferred by a
Participant under this Section 17.7.

         17.8 USE OF PROCEEDS. Proceeds from the sale of shares of Common Stock
pursuant to Incentives granted under this Plan shall constitute general funds of
the Company.

         17.9 LEGEND. Each certificate representing shares of Restricted Stock
issued to a Participant shall bear the following legend, or a similar legend
deemed by the Company to constitute an appropriate notice of the provisions
hereof (any such certificate not having such legend shall be surrendered upon
demand by the Company and so endorsed):

                                       20

         The following legend shall be inserted on a certificate evidencing
Common Stock issued under the Plan if the shares were not issued in a
transaction registered under the applicable federal and state securities laws:

                           been acquired by the holder for investment and not

                           issued pursuant to exemptions from the registration
                           requirements of applicable state and federal
                           securities laws, and may not be offered for sale,
                           sold or transferred other than pursuant to effective
                           registration under such laws, or in transactions

                              EMPLOYMENT AGREEMENT

     This Employment Agreement (this "Agreement") is entered into this date by
and between ALAMOSA PCS, LLC, a Texas Limited Liability Company, having its
principal executive office located at 4403 Brownfield Highway, Lubbock, Texas
79407 (the "Company"), and DAVID E. SHARBUTT, an individual residing at Lubbock,
Texas (the "Employee").

                                   WITNESSETH:

     WHEREAS, the parties are entering into this Agreement to set forth and
confirm their respective rights and obligations with respect to the Employee's
employment by the Company.

     NOW, THEREFORE, in consideration of the mutual covenants herein contained,
the parties hereto mutually agree as follows:

     1. EMPLOYMENT; TERM; DUTIES. The Company hereby employs the Employee as
Chief Executive Officer ("CEO"). The term of the Employee's employment, pursuant
to this Agreement, will commence on October 1, 1999, (the "Commencement Date")
and will continue until September 30, 2002, or the termination of this Agreement
as described in Section 5 hereof, whichever shall occur first. The Employee
hereby accepts such employment, and agrees to devote his full time and effort to
the business and affairs of the Company with such duties consistent with the
Employee's position as may be assigned to him from time to time by the Board of
Managers of the Company. Notwithstanding the foregoing, the Company acknowledges
that the Employee has other business interests and ownerships as well as serving
on the Boards of Directors of other companies in which the Employee is a
stockholder or owner. Subject to the provisions of Sections 7 through 10 hereof,
the Company acknowledges and consents to the continuation of these ownerships
and relationships, provided they do not interfere with the Employee's duties
under this Agreement. Notwithstanding anything to the contrary in this
Agreement, nothing in this Agreement shall be deemed to impose any obligation on
the Company or any of its subsidiaries to continue to employ the Employee, or on
the Employee to remain in the employ of the Company or any of its subsidiaries.

     2. COMPENSATION. In consideration of all services rendered by the Employee
as CEO during the term of his employment, pursuant to this Agreement, the
Company will provide the Employee with the following compensation:

     (a) BASE SALARY. The Company will pay the Employee a base salary at the
     annual rate of $175,000.00, payable periodically but no less often than
     semi-monthly, in substantially equal amounts, in accordance with the
     Company's payroll practices from time to time in effect. The Company will

<PAGE>   2


     review the Employee's base salary at least once each year and may, in its
     discretion, increase the Employee's base salary.

     (b) BONUS. In addition to the Employee's base salary, the Employee shall be
     eligible to receive a bonus (a "Quarterly Bonus") for each calendar quarter
     in an amount, if any, determined as follows: In each calendar quarter,
     beginning with the quarter ending December 31, 1999, Employee's Quarterly
     Bonus shall be equal to the sum of (1) plus (2) as follows:

          (1) $21,875.00 multiplied by the percentage set forth opposite each
          Expected Milestone set forth in the attached EXHIBIT "A", incorporated
          herein by reference, which is achieved for that calender quarter.

          (2) $21,875.00 multiplied by the percentage set forth opposite each
          Exceptional Milestone set forth in EXHIBIT "A" which is achieved for
          that calendar quarter.

     If any particular Expected Milestone or Exceptional Milestone is not
     achieved for any calendar quarter, that percentage share of the dollar
     amount specified in (1) or (2) above, as the case may be, shall not be
     payable as part of the Quarterly Bonus. The Expected Milestones,
     Exceptional Milestones and percentages set forth on EXHIBIT "A" may be
     changed by the Company at any time and from time to time, but any such
     change shall not apply earlier than the calendar quarter following the
     calendar quarter in which such change is made by the Company and
     communicated to the Employee.

     Any Quarterly Bonus owing to the Employee shall be paid within forty-five
     (45) days following the end of the applicable calendar quarter.

     (c) UNIT OPTIONS. If, on June 30, 2000, the Company has not become a
     wholly-owned subsidiary of Alamosa PCS Holdings, Inc., a Delaware
     corporation ("Holdings"), then on said date the Company will convert the
     membership interests in the Company to forty-eight million five hundred
     thousand (48,500,000) membership units, and shall grant to the Employee
     options to purchase membership units in the Company as follows:

          (1) First Option. An option (the "First Option") to purchase two
          hundred forty-two thousand five hundred (242,500) membership units in
          the Company at a per unit purchase price equal to One Dollar and
          Fifteen Cents ($1.15), said First Option to be fully vested and
          immediately exercisable by the Employee, and thereafter be exercisable
          at any time until January 5, 2009, in accordance with


EMPLOYMENT AGREEMENT       PAGE 2 OF 22
ALAMOSA PCS LLC and David E. Sharbutt


<PAGE>   3


          the option agreement to be entered into between the Company and the
          Employee as of June 30, 2000, upon terms and conditions substantially
          similar to the terms and conditions of the Nonqualified Stock Option
          Agreement entered into by the Employee pursuant to the Alamosa PCS
          Holdings, Inc. 1999 Long-Term Incentive Plan.

          (2) Second Option. An option (the "Second Option") to purchase one
          million four hundred fifty-five thousand (1,455,000) membership units
          in the Company at a per unit purchase price equal to Fifteen Dollars
          ($15.00), said Second Option, subject to Section 6 hereof, to vest and
          be exercisable by the Employee in three (3) equal installments of four
          hundred eighty-five thousand (485,000) membership units each on
          September 30, 2000, September 30, 2001, and September 30, 2002,
          respectively, and thereafter be exercisable at any time until January
          5, 2009, in accordance with the option agreement to be entered into
          between the Company and the Employee as of June 30, 2000, upon terms
          and conditions substantially similar to the terms and conditions of
          the Nonqualified Stock Option Agreement entered into by the Employee
          pursuant to the Alamosa PCS Holdings, Inc. 1999 Long-Term Incentive
          Plan.

     (d) LIFE INSURANCE. The Company will provide at least $5,000,000.00 term
     life insurance on the life of the Employee during the term of the
     Employee's employment. The Company shall pay for all costs attributable to
     such coverage. Such life insurance shall be at least ten (10) year level
     premium term life insurance on the life of the Employee. The Employee shall
     have the right to designate the beneficiary of such policy or policies.
     Should the Employee not be insurable at the time of his employment under
     this Agreement, there will be no obligation upon the Company to provide
     such life insurance. If the Employee's employment terminates during the
     term of this Agreement or at the termination of the Employee's employment
     pursuant to this Agreement, the Employee may assume the premium obligations
     of this policy, in which event the Company shall assign all its rights in
     the policy to the Employee. In the event the Employee desires to assume the
     premium obligations under this policy and at the time of the Employee's
     termination of employment the Company has prepaid any premiums on the
     policy, the Employee shall pay to the Company the amount of any prepayment
     attributable to any period of coverage after the Employee's termination of
     employment.

The Employee will receive no additional compensation for serving the Company in
any other capacity, such as Chairman of the Board of Directors or any similar
position.

     3. EMPLOYEE BENEFITS. The Employee will be entitled to participate in all
incentive, retirement, profit-sharing, life, medical, disability and other
benefit plans and programs (collectively "Benefit Plans") as are from time to
time generally available to other executives of the Company with comparable
responsibilities, subject to the provisions of those programs. Without limiting
the generality of the foregoing, the Company will provide the Employee with
basic health and medical benefits on the terms that such benefits are provided
to other executives of the Company with comparable responsibilities. The
Employee will also be entitled to holidays, sick leave and vacation in
accordance with the Company's policies as they may change from time to time, but
in no event shall the Employee be entitled to less than four (4) weeks paid
vacation per year.

     4. EXPENSES.

     (a) Reimbursement for Expenses. The Company will promptly reimburse the
     Employee, in accordance with the Company's policies and practices in effect
     from time to time, for all expenses reasonably incurred by the Employee in
     performance of the Employee's duties under this Agreement, including
     reimbursement for miles driven by the Employee in furtherance of the
     Company's business ("Business Mileage").

          (1) Reimbursement for Business Mileage shall be at the standard
          mileage rate allowed by the Internal Revenue Service ("IRS") for the
          taxable year and set forth in the appropriate IRS publication.

          (2) Business mileage does not include commuting from Employee's
          residence to the Company's headquarters.

          (3) Employee is responsible for proper substantiation and reporting of
          Business Mileage and/or actual expenses.

          (4) Employee acknowledges that the payment to him of a monthly vehicle
          allowance plus the standard mileage rate may result in taxable income
          if the business portion of actual automobile expenses is less than the
          total amount paid to employee under this subsection, or if employee
          does not maintain the records required by the Internal Revenue Code
          and the Regulations thereunder. Employee has been advised to consult a
          tax advisor to determine the taxability of payments under this
          subsection, and the record keeping requirements associated with the
          travel and expenses associated with such payments.

incorporated by reference into the Sprint Agreement. Furthermore, upon the
expiration of this Agreement or the termination of this Agreement prior to
September 30, 2002, for any reason, the Employee expressly agrees not to engage
or participate, directly or indirectly, either as an Employee, Employer,
Consultant, Agent, Principal, Partner, Stockholder, Corporate Officer, Director,
Shareholder, Member, Investor or in any other individual or representative
capacity, for a period of two (2) years in any business that is in competition
with the Business and that is located within and/or doing business within the
Service Area as defined above as in existence during the term of the Employee's
employment with the Company. The parties agree that the Company has a legitimate
interest in protecting the Business and goodwill of the Company that has
developed in the areas of the Company's Business and in the geographical areas
of this Covenant Not To Compete as a result of the operations of the Company.
The parties agree that the Company is entitled to protection of its interests in
these areas. The parties further agree that the limitations as to time,
geographical area, and scope of activity to be restrained do not impose a
greater restraint upon Employee than is necessary to protect the goodwill or
other business interest of the Company. The parties further agree that in the
event of a violation of this Covenant Not To Compete, that the Company shall be
entitled to the recovery of damages from Employee and/or an injunction against
Employee for the breach or violation or continued breach or violation of this
Covenant. The Employee agrees that if a court of competent jurisdiction
determines that the length of time or any other restriction, or portion thereof,
set forth in this Section 7 is overly restrictive and unenforceable, the court
may reduce or modify such restrictions to those which it deems reasonable and
enforceable under the circumstances, and as so reduced or modified, the parties
hereto agree that the restrictions of this Section 7 shall remain in full force

and effect. The Employee further agrees that if a court of competent
jurisdiction determines that any provision of this Section 7 is invalid or
against public policy, the remaining provisions of this Section 7 and the
remainder of this Agreement shall not be affected thereby, and shall remain in
full force and effect.

and damages to the Company. The parties further agree that in the event of a

          (a) MEDIATION. The Company and Employee agree to mediate any dispute
          arising under the applicable provisions of this Agreement. In the
          event of any such dispute, the parties, within thirty (30) days of a
          written request for mediation, shall attend, in good faith, a
          mediation in order to make a good faith reasonable effort to resolve
          such dispute arising under this Agreement. The parties shall attempt,
          in good faith, to agree to a mediator. If unable to so agree, the
          parties, in that event, will move to arbitration as provided in this
          Agreement and there will be no mediation. If this good faith mediation
          effort fails to resolve any dispute arising under this Agreement, the
          Company and Employee agree to arbitrate any dispute arising under this
          Agreement. This arbitration shall occur only after the mediation
          process described herein.

          (b) ARBITRATION. The Company and Employee agree, as concluded by the
          parties to this Agreement on the advice of their counsel, and as
          evidenced by the signatures of the parties and of their respective
          attorneys, that all questions as to rights and obligations arising
          under the terms of this Agreement are subject to arbitration and such
          arbitration shall be governed by the provisions of the Texas General
          Arbitration Act (Texas Civil Practice and Remedies Code Section
          171.001 et seq as it may be amended from time to time).

          (c) DEMAND FOR ARBITRATION. If a dispute should arise under this
          Agreement, either party may within thirty (30) days make a demand for
          arbitration by filing a demand in writing with the other.

          (d) APPOINTMENT OF ARBITRATORS. The parties to this Agreement may
          agree on one arbitrator, but in the event that they cannot so agree,
          there shall be three arbitrators, one named in writing by each of the
          parties within thirty (30) days after demand for arbitration is made,
          and a third to be chosen by the two so named. The arbitrators among
          themselves shall appoint a presiding arbitrator. Should either party
          fail to timely join in the appointment of the arbitrators, the
          arbitrators shall be appointed in accordance with the provisions of
          Texas Civil Practice and Remedies Code Section 171.041.

          (e) HEARING. All arbitration hearings conducted under the terms of
          this Agreement, and all judicial proceedings to enforce any of the
          provisions of this Agreement, shall take place in Lubbock County,
          Texas. The hearing before the arbitrators of the matter to be
          arbitrated shall be at the time and place within that County selected
          by the arbitrators or if deemed by the arbitrators to be more
          convenient for the parties or more economically feasible, may be
          conducted in any city within the Service Area as referred to in
          Section 7 hereof or within the State of Texas.

<PAGE>   16


          (f) ARBITRATION AWARD. If there is only one arbitrator, his or her
          decision shall be binding and conclusive. The submission of a dispute
          to the arbitrators and the rendering of their decision shall be a
          condition precedent to any right of legal action on the dispute. A
          judgment confirming the award of the arbitrators may be rendered by
          any court having jurisdiction; or the court may vacate, modify, or
          correct the award in accordance with the provisions of the Texas
          General Arbitration Act (Texas Civil Practice and Remedies Code ss.
          171.087 et seq as it may be amended from time to time).

          (g) COSTS OF ARBITRATION. The costs and expenses of arbitration,
          including the fees of the arbitrators but excluding any attorneys'
          fees, shall be advanced by the Company, but will ultimately be borne
          by the losing party or in such proportions as the arbitrators shall
          determine.

          (h) CONDUCT OF ARBITRATION. Any arbitration brought under the terms of
          this Agreement shall be conducted in the following manner:

               (1) Time Limitations. The parties agree that the following time
               limitations shall govern the arbitration proceedings conducted
               under the terms of this Agreement:

                    (a) Any demand for arbitration must be filed within thirty
                    (30) days of the date the mediation is deemed unsuccessful,
                    or thirty (30) days after the date of the written request
                    for mediation, whichever is later.

                    (b) Each party must select an arbitrator within thirty (30)
                    days of receipt of notice that an arbitration proceeding has
                    commenced. In the event that no such selection is made, the
                    arbitrator selected by the other party may conduct the
                    arbitration proceeding without selecting any other
                    arbitrator.

                    (c) The hearing must be held within sixty (60) days of the
                    date on which the third arbitrator is selected.

                    (d) Hearing briefs must be submitted no later than ten (10)
                    days after the hearing.

                    (e) The arbitration award must be made within thirty (30)
                    days of the receipt of hearing briefs.

               (2) Discovery in Arbitration Proceedings. The parties agree that
               discovery may be conducted in the course of the arbitration
               proceeding in accordance with the following provisions:

                    (a) Each party may notice no more than three (3) depositions
                    in total, including both witnesses adherent to the adverse
                    party and third-party witnesses.

                    (b) Each party may serve no more than twenty-five (25)
                    requests for admission on the other party. No requests may
                    be served within ten (10) days of the date of hearing,
                    unless the parties otherwise stipulate. All requests for
                    admission shall be responded to within ten (10) days of
                    service of the requests, unless the parties otherwise
                    stipulate.

                    (c) Each party may serve no more than fifty (50)
                    interrogatories on the other party. No interrogatory shall
                    contain subparts, or concern more than one topic or subject
                    of inquiry. Interrogatories may not be phrased so as to
                    circumvent the effect of this clause. No interrogatories may
                    be served within ten (10) days of the date of hearing,
                    unless the parties otherwise stipulate. All interrogatories
                    shall be responded to within ten (10) days of service of the
                    interrogatories, unless the parties otherwise stipulate.

                    (d) Each party may serve no more than ten (10) requests for
                    production of documents on the other party. No request for
                    production of documents shall contain subparts, or seek more
                    than one type of document. Requests for production of
                    documents may not be phrased so as to circumvent the effect
                    of this clause. Unless the parties otherwise stipulate,
                    requests for production of documents may not be served
                    within ten (10) day of the date of hearing, and all requests
                    for production of documents shall be responded to within ten
                    (10) days of service of the requests.

                    (e) If any party contends that the other party has served
                    discovery requests in a manner not permitted by this
                    Section, or that the other party's response to a discovery
                    request is unsatisfactory, the party may request the
                    presiding arbitrator to resolve such discovery disputes. The
                    presiding arbitrator shall prescribe the procedure by which
                    such disputes are resolved. Any discovery dispute may be
                    handled by telephone conference among the parties and the
                    presiding arbitrator.

     12. SUCCESSORS; BINDING AGREEMENT; ASSIGNMENT. The Company shall require
any successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business or assets of the Company
to expressly assume and agree in writing to perform this Agreement in the same
manner and to the same extent that the Company would be required to perform it
if no such succession had taken place, provided that the Employee must be given
the position as the Chief Executive Officer ("CEO") with the same authority,
powers and responsibilities set forth in Section 1 hereof with respect to the
subsidiary or subdivision which operates the business of the Company as it
exists on the date of such business combination. Failure of the Company to
obtain such express assumption and agreement at or prior to the effectiveness of
any such succession shall be a breach of this Agreement and shall entitle the
Employee to compensation and benefits from the Company in the same amount and on
the same terms to which the Employee would be entitled hereunder if the Company
terminated the Employee's employment without Cause, except that all options will
be immediately vested. For purposes of implementing the foregoing, the date on
which any such succession becomes effective shall be deemed the date of
termination. As used in this Agreement, "Company" shall mean the Company as
hereinbefore defined and any successor to its business or assets as aforesaid
which assumes and agrees to perform this Agreement by operation of law, or
otherwise. The Company may not assign this Agreement, (i) except in connection
with, and to the acquiror of, all or substantially all of the business or assets
of the Company, provided such acquiror expressly assumes and agrees in writing
to perform this Agreement as provided in this Section, and (ii) except in
connection with the Company becoming a wholly-owned subsidiary of Holdings, in
which event the Company may assign this Agreement and all of the Company's
rights and obligations hereunder to Holdings. The Employee may not assign his
rights or delegate his duties or obligations under this Agreement.

     13. NOTICE. Any notices or other communications required or permitted to be
given hereunder shall be in writing and shall be deemed to have been duly made
or given when hand delivered, one (1) business day after being transmitted by
telecopier (confirmed by mail) or sent by overnight courier against receipt, or
five (5) days after being mailed by registered or certified mail, postage
prepaid, return receipt requested, to the party to whom such communication is
given at the address set forth below, which address may be changed by notice

     14. MISCELLANEOUS.

          (a) SEVERABILITY. If any provision of this Agreement shall be declared
          to be invalid or unenforceable, in whole or in part, such invalidity

          and such officer as may be designated by the Board of Managers of the
          Company to execute such a waiver, modification or discharge. No waiver
          by either party hereto at any time of any breach by the other party
          hereto of, or failure to be in compliance with, any condition or
          provision of this Agreement to be performed by such other party shall
          be deemed a waiver of similar or dissimilar provisions or conditions
          at the time or at any prior or subsequent time. No agreements or
          representations, oral or otherwise, express or implied, with respect
          to the subject matter hereof have been made by either party which are
          not expressly set forth in this Agreement or in the documents attached
          as Exhibits to this Agreement.

          (c) INVALID PROVISIONS. Should any portion of this Agreement be
          adjudged or held to be invalid, unenforceable or void, such holding
          shall not have the effect of invalidating or voiding the remainder of
          this Agreement and the parties hereby agree that the portion so held
          invalid, unenforceable or void shall, if possible, be deemed amended
          or reduced in scope, or otherwise be stricken from this Agreement to

                              EMPLOYMENT AGREEMENT

         This Employment Agreement (this "Agreement") is entered into this date
by and between ALAMOSA PCS, LLC, a Texas Limited Liability Company, having its
principal executive office located at 4403 Brownfield Highway, Lubbock, Texas
79407 (the "Company"), and KENDALL COWAN, an individual residing at 8402
Vicksburg, Lubbock, Texas (the "Employee").

                                   WITNESSETH:

         WHEREAS, the parties are entering into this Agreement to set forth and
confirm their respective rights and obligations with respect to the Employee's
employment by the Company.

         NOW, THEREFORE, in consideration of the mutual covenants herein
contained, the parties hereto mutually agree as follows:

         1. EMPLOYMENT; TERM; DUTIES. The Company hereby employs the Employee as
Chief Financial Officer ("CFO"). The term of the Employee's employment, pursuant
to this Agreement, will commence on December 1, 1999, (the "Commencement Date")
and will continue until November 30, 2004, or the termination of this Agreement
as described in Section 6 hereof, whichever shall occur first. The Employee
hereby accepts such employment, and agrees to devote his full time and effort to
the business and affairs of the Company with such duties consistent with the
Employee's position as may be assigned to him from time to time by the Board of
Managers of the Company and/or the Chief Executive Officer ("CEO") of the
Company. The CFO shall report to the CEO of the Company. Notwithstanding the
foregoing, the Company acknowledges that the Employee has other business
interests and ownerships as well as serving on the Boards of Directors of other
companies in which the Employee is a stockholder or owner. Subject to the
provisions of Sections 8 through 11 hereof, the Company acknowledges and
consents to the continuation of these ownerships and relationships, provided
they do not interfere with the Employee's duties under this Agreement.
Notwithstanding anything to the contrary in this Agreement, nothing in this
Agreement shall be deemed to impose any obligation on the Company or any of its
subsidiaries to continue to employ the Employee, or on the Employee to remain in
the employ of the Company or any of its subsidiaries.

         2. COMPENSATION. In consideration of all services rendered by the
Employee as CFO during the term of his employment, pursuant to this Agreement,
the Company will provide the Employee with the following compensation:

                  (a) BASE SALARY. The Company will pay the Employee a base
                  salary at the annual rate of $150,000.00, payable periodically
                  but no less often than semi-monthly, in substantially equal
                  amounts, in accordance with the

Employment Agreement       PAGE 1 OF 21
Alamosa PCS LLC and Kendall Cowan


<PAGE>   2


                  Company's payroll practices from time to time in effect. The
                  Company will review the Employee's base salary at least once
                  each year and may, in its discretion, increase the Employee's
                  base salary.

                  (b) BONUS. In addition to the Employee's base salary, the
                  Employee shall be eligible to receive a bonus (a "Quarterly
                  Bonus") for each calendar quarter in an amount, if any,
                  determined as follows: In each calendar quarter, beginning
                  with the quarter ending December 31, 1999, Employee's
                  Quarterly Bonus shall be equal to the sum of (1) plus (2) as
                  follows:

                                            (1) $18,750.00 multiplied by the
                           percentage set forth opposite each Expected Milestone
                           set forth in the attached EXHIBIT "A", incorporated
                           herein by reference, which is achieved for that
                           calender quarter.

                           (2) $18,750.00 multiplied by the percentage set forth
                           opposite each Exceptional Milestone set forth in
                           EXHIBIT "A" which is achieved for that calendar
                           quarter.

                  If any particular Expected Milestone or Exceptional Milestone
                  is not achieved for any calendar quarter, that percentage
                  share of the dollar amount specified in (1) or (2) above, as
                  the case may be, shall not be payable as part of the Quarterly
                  Bonus. The Expected Milestones, Exceptional Milestones and
                  percentages set forth on EXHIBIT "A" may be changed by the
                  Company at any time and from time to time, but any such change
                  shall not apply earlier than the calendar quarter following
                  the calendar quarter in which such change is made by the
                  Company and communicated to the Employee.

                  Any Quarterly Bonus owing to the Employee shall be paid within
                  forty-five (45) days following the end of the applicable
                  calendar quarter.

                  (c) UNIT OPTIONS. If, on June 30, 2000, the Company has not
                  become a wholly-owned subsidiary of Alamosa PCS Holdings,
                  Inc., a Delaware corporation ("Holdings"), then on said date
                  the Company will convert the membership interests in the
                  Company to forty-eight million five hundred thousand
                  (48,500,000) membership units, and shall grant to the Employee
                  options to purchase membership units in the Company as

                           purchase price equal to Fifteen Dollars ($15.00),

                           substantially similar to the terms and conditions of
                           the Nonqualified Stock Option Agreement entered into
                           by the Employee pursuant to the Alamosa PCS Holdings,
                           Inc. 1999 Long-Term Incentive Plan.

                           rate may result in taxable income if the business
                           portion of actual automobile expenses is less than
                           the total amount paid to employee under this
                           subsection, or if employee does not maintain the
                           records required by the Internal Revenue Code and the

                  eligible to receive a disability benefit.

                  (b) The term "cause" in the event of termination of the
                  Employee's employment by the Company means (i) any breach of
                  Sections 8 or 10 of this Agreement by Employee which has a
                  materially adverse effect on the Company and which is not or
                  cannot be cured within thirty (30) days after notice from the
                  CEO or the Board of Managers of the Company thereof; (ii)
                  commission of any act of fraud, embezzlement or dishonesty by
                  the Employee that is materially and demonstrably injurious to
                  the Company; (iii) any act or omission by Employee which
                  constitutes a uncured default or breach of that certain Sprint
                  PCS Management Agreement dated July 17, 1998 and as it may be
                  amended from time to time or any other similar Sprint
                  Management Agreement to which the Company or any of its
                  affiliates or subsidiaries may be a party ("the Sprint
                  Agreement"); or (iv) any other intentional misconduct by the
                  Employee adversely affecting the business or affairs of the
                  Company in a material manner. The term "intentional misconduct
                  by the Employee adversely affecting the business or affairs of
                  the Company" shall mean such misconduct that is detrimental to
                  the business or the reputation of the Company as it is
                  perceived both by the general public and the
                  telecommunications industry.

                  (c) The term "cause" in the event of termination of the
                  Employee's employment by the Employee means (i) a dispute
                  between the Company and the Employee over accounting issues
                  provided, however, any such dispute shall not constitute
                  "cause" if the Company, at its own expense, elects to have a
                  nationally recognized public accounting firm resolve the
                  accounting issue dispute and such accounting firm agrees with
                  the Company's position regarding such accounting issue; (ii)
                  termination of employment by the Employee at any time more
                  than six (6) months after the date of termination by the

                  Chief Executive Officer of the Company ("Sharbutt's
                  Termination"), provided the Employee, within sixty (60) days
                  of the date of Sharbutt's Termination, notifies the Company in
                  writing of his intention to terminate employment under this
                  provision and specifies in such notice his date of employment
                  termination; (iii) the requirement by the Company of

                  the relocation of the Employee from Lubbock, Texas; (iv) the
                  change in job responsibilities of the Employee resulting in
                  the demotion of the Employee from the position of CFO, which
                  demotion is caused by something other than would be cause for
                  termination of the Employee's employment by the Company for
                  cause and other than the non-performance of the Employee as
                  defined later herein; or (v) the failure of the Company to
                  complete its initial public offering (IPO) on or before
                  December 31, 2000.

                  (d) The term "non-performance by the Employee" in the event of
                  termination of the Employee's employment by the Company means
                  the determination by a super-majority (greater than 75%) of
                  the members of the Board of Managers of the Company, in their
                  sole and absolute discretion, that the Employee is not
                  performing his duties under this Agreement after the CEO or
                  the Board of Managers of the Company has delivered to the
                  Employee written notice which specifically identifies the
                  manner in which the CEO or the Board believes he is not
                  performing his duties and which is not or cannot be cured
                  within 15 days after such written notice is delivered to the
                  Employee.

         7. CONSEQUENCES OF TERMINATION.

                  (a) CONSEQUENCES OF TERMINATION ON EMPLOYEE'S DEATH OR
                  DISABILITY. If the Employee's employment is terminated prior
                  to November 30,2004, because of the Employee's death or
                  disability, (i) subject to Section 7(g) hereof, this Agreement
                  terminates immediately; (ii) Employee or his legal
                  representative or estate, as the case may be, shall be
                  eligible to exercise any options granted and vested pursuant
                  to Section 2(c) hereof at the time of such death or
                  disability, plus, if such death or disability does not occur
                  on November 30 of a given year, a fractional portion of those
                  options which would have vested and become exercisable
                  pursuant to Section 2(c) hereof on the November 30 immediately
                  following such death or disability based on a fraction whose
                  numerator is the number of months (including the month in
                  which the date of death or disability occurs) since the
                  previous November 30 and whose denominator is twelve (12), in
                  accordance with the provisions of Section 2(c) hereof and the
                  option agreement referred to therein, and any other options
                  granted to the Employee shall be forfeited; (iii) the Company
                  will pay the Employee, or his legal representative or estate,
                  as the case may be, in full satisfaction of all of its
                  compensation (base salary and bonus) obligations under this
                  Agreement, an amount equal to the sum of any base salary due
                  to the Employee through the last day of employment, plus any
                  accrued bonus to which the Employee may have been entitled on
                  the last day of employment, but had not yet been received; and
                  (iv) the Employee's benefits and rights under any Benefit Plan
                  shall be paid, retained or

                  forfeited in accordance with the terms of such plan; provided,
                  however, that Employer shall have no obligation to make any
                  payments toward these benefits for Employee from and after
                  termination.

                  (b) CONSEQUENCES OF TERMINATION BY THE COMPANY FOR ANY REASON
                  OTHER THAN FOR CAUSE OR FOR NON-PERFORMANCE OF EMPLOYEE.

                           (1) If the Employee's employment is terminated by the
                           Company prior to November 30, 2004, for any reason

                           representative or estate, as the case may be, shall

                           exercised pursuant to Section 2(c) hereof, which
                           options shall be deemed vested as of the date of the
                           Employee's termination of employment regardless of
                           whether or not they are in fact otherwise vested
                           pursuant to Section 2(c) hereof on said date, in
                           accordance with the provisions of Section 2(c) hereof
                           and the option agreement referred to therein; (iii)
                           the Company will pay the Employee, in full
                           satisfaction of all of its compensation (base salary
                           and bonus) obligations under this Agreement, an
                           amount equal to the sum of any base salary due to the
                           Employee through the last day of employment, plus any
                           accrued bonus to which the Employee may have been
                           entitled on the last day of employment, but had not
                           yet been received; (iv) the Company will pay the
                           Employee, within sixty (60) days of such termination,
                           a lump sum severance payment equal to one (1) year's
                           base salary as in effect at the date of employment
                           termination; and (v) the Employee's benefits and
                           rights under any Benefit Plan, other than any basic
                           health and medical benefit plan, shall be paid,
                           retained or forfeited in accordance with the terms of
                           such plan; provided, however, that Employer shall
                           have no obligation to make any payments toward these
                           benefits for Employee from and after termination.

                           (2) Any payment pursuant to clause (b)(1)(iv) above
                           (the "Termination Payment"):

                                    a. will be subject to offset for any
                                    advances, amounts receivable, and loans,
                                    including accrued interest, outstanding on
                                    the date of the employment termination; and

                                    b. will not be subject to offset on account
                                    of any remuneration paid or payable to the

                                    Employee may obtain, whether

                                    during or after the period during which the
                                    Termination Payment is made, and the
                                    Employee shall have no obligation whatever
                                    to seek any subsequent employment.

                  (c) CONSEQUENCES OF TERMINATION FOR CAUSE BY THE COMPANY. If
                  the Employee's employment is terminated by the Company prior
                  to November 30, 2004, for cause, (i) subject to Section 7(g)
                  hereof, this Agreement terminates immediately; (ii) Employee
                  shall not be eligible to exercise and shall forfeit any
                  options granted (whether or not vested) pursuant to Section

                  Employee, in full satisfaction of all of its compensation
                  (base salary and bonus) obligations under this Agreement, an
                  amount equal to the sum of any base salary due to the Employee
                  through the last day of employment, plus any accrued bonus to
                  which the Employee may have been entitled on the last day of
                  employment, but had not yet been received; and(iv) the
                  Employee's benefits and rights under any Benefit Plan shall be
                  paid, retained or forfeited in accordance with the terms of
                  such plan; provided, however, that Employer shall have no
                  obligation to make any payments toward these benefits for
                  Employee from and after termination.

                  (d) CONSEQUENCES OF TERMINATION BY THE EMPLOYEE FOR ANY REASON
                  OTHER THAN FOR CAUSE OR EMPLOYEE'S DEATH OR DISABILITY. If,
                  upon forty-five (45) days' prior written notice to the Company
                  by the Employee, the Employee's employment is terminated by
                  the Employee prior to November 30, 2004, for any reason other
                  than for cause or Employee's death or disability, (i) subject
                  to Section 7(g) hereof, this Agreement terminates immediately;

                  case may be, shall be eligible to exercise any options granted
                  and vested, but not exercised pursuant to Section 2(c) hereof
                  at the time of such employment termination, in accordance with
                  the provisions of Section 2(c) hereof and the option agreement

                  than any basic health and medical benefit plan, shall be
                  retained or forfeited in accordance with the terms of such
                  plan; provided, however, that Employer shall have no

                  obligation to make any payments toward these benefits for
                  Employee from and after termination.

                  (e) CONSEQUENCES OF TERMINATION BY THE EMPLOYEE FOR CAUSE.

                           (1) If, upon forty-five (45) days' prior written
                           notice to the Company by the Employee, the Employee's
                           employment is terminated by the Employee prior to
                           November 30, 2004, for cause (i) subject to Section
                           7(g) hereof, this Agreement terminates immediately;
                           (ii) Employee or his legal representative or estate,

                           hereof at the time of such employment termination,
                           plus, if such employment termination does not occur
                           on November 30 of a given year, those options which
                           would have vested and become exercisable pursuant to
                           Section 2(c) hereof on the November 30 immediately
                           following such employment termination, in accordance
                           with the provisions of Section 2(c) hereof and the
                           option agreement referred to therein, and any other
                           options granted to the Employee shall be forfeited;
                           (iii) the Company will pay the Employee, in full
                           satisfaction of all of its compensation (base salary

                           entitled on the last day of employment, but had not
                           yet been received; (iv) the Company will pay the
                           Employee, within sixty (60) days of such termination,

                           base salary as in effect at the date of employment
                           termination or the unpaid balance of the annual base
                           salary which would have been payable to Employee
                           through November 30, 2004, whichever amount shall be
                           less; and (v) the Employee's benefits and rights
                           under any Benefit Plan, other than any basic health
                           and medical benefit plan, shall be paid, retained or
                           forfeited in accordance with the terms of such plan;
                           provided, however, that Employer shall have no
                           obligation to make any payments toward these benefits
                           for Employee from and after termination.

                           (2) Any payment pursuant to clause (e)(1)(iv) above

                                    b. will not be subject to offset on account
                                    of any remuneration paid or payable to the

                                    Employee may obtain, whether during or after
                                    the period during which the Termination
                                    Payment is made, and the Employee shall have
                                    no obligation whatever to seek any
                                    subsequent employment.

                  (f) CONSEQUENCES OF TERMINATION BY THE COMPANY FOR
                  NON-PERFORMANCE BY THE EMPLOYEE. If the Employee's employment
                  is terminated by the Company prior to November 30, 2004, for
                  non-performance by the Employee (i) subject to Section 7(g)
                  hereof, this Agreement terminates immediately; (ii) Employee
                  or his legal representative or estate, as the case may be,
                  shall be eligible to exercise any options granted and vested
                  but not exercised pursuant to Section 2(c) hereof at the time
                  of such employment termination, in accordance with the
                  provisions of Section 2(c) hereof and the option agreement
                  referred to therein, and any other options granted to the
                  Employee shall be forfeited; (iii) the Company will pay the
                  Employee, in full satisfaction of all of its compensation
                  (base salary and bonus) obligations under this Agreement, an
                  amount equal to the sum of any base salary due to the Employee
                  through the last day of employment, plus any accrued bonus to
                  which the Employee may have been entitled on the last day of

                  Employee's benefits and rights under any Benefit Plan, other
                  than any basic health and medical benefit plan, shall be paid,
                  retained or forfeited in accordance with the terms of such
                  plan; provided, however, that Employer shall have no
                  obligation to make any payments toward these benefits for
                  Employee from and after termination.

                  (g) PRESERVATION OF CERTAIN PROVISIONS. Notwithstanding any
                  provisions of this Agreement to the contrary, the provisions
                  of Sections 8 through 13 hereof shall survive the expiration
                  or termination of this Agreement as necessary to give full
                  effect to all of the provisions of this Agreement.

         8. NON-COMPETITION BY EMPLOYEE. During the term of this Agreement, the
Employee shall not, directly or indirectly, either as an Employee, Employer,
Consultant, Agent, Principal, Partner, Corporate Officer, Director, Shareholder,
Member, Investor or in any other individual or representative capacity, engage
or participate in any business that is in competition in any manner whatever
with the business of the Company. For these purposes, the business of the
Company is establishing and providing mobile wireless communications services
(the "Business"), including all aspects of the Business within the Service Area
as that term is defined in the Schedule of Definitions referred to in and
incorporated by reference into the Sprint Agreement. Furthermore,


Employment Agreement       PAGE 10 OF 21
Alamosa PCS LLC and Kendall Cowan


<PAGE>   11

upon the expiration of this Agreement or the termination of this Agreement prior
to November 30, 2004, for any reason, the Employee expressly agrees not to
engage or participate, directly or indirectly, either as an Employee, Employer,
Consultant, Agent, Principal, Partner, Stockholder, Corporate Officer, Director,
Shareholder, Member, Investor or in any other individual or representative
capacity, for a period of two (2) years in any business that is in competition
with the Business and that is located within and/or doing business within the
Service Area as defined above as in existence during the term of the Employee's
employment with the Company. The parties agree that the Company has a legitimate
interest in protecting the Business and goodwill of the Company that has
developed in the areas of the Company's Business and in the geographical areas
of this Covenant Not To Compete as a result of the operations of the Company.
The parties agree that the Company is entitled to protection of its interests in
these areas. The parties further agree that the limitations as to time,
geographical area, and scope of activity to be restrained do not impose a
greater restraint upon Employee than is necessary to protect the goodwill or
other business interest of the Company. The parties further agree that in the
event of a violation of this Covenant Not To Compete, that the Company shall be
entitled to the recovery of damages from Employee and/or an injunction against
Employee for the breach or violation or continued breach or violation of this
Covenant. The Employee agrees that if a court of competent jurisdiction
determines that the length of time or any other restriction, or portion thereof,
set forth in this Section 8 is overly restrictive and unenforceable, the court
may reduce or modify such restrictions to those which it deems reasonable and
enforceable under the circumstances, and as so reduced or modified, the parties
hereto agree that the restrictions of this Section 8 shall remain in full force
and effect. The Employee further agrees that if a court of competent
jurisdiction determines that any provision of this Section 8 is invalid or
against public policy, the remaining provisions of this Section 8 and the
remainder of this Agreement shall not be affected thereby, and shall remain in
full force and effect.

nominees, any Confidential Information of any member of the Company Group
(regardless of whether developed by the Employee) without the prior written
consent of the Company. Employee acknowledges that the use or disclosure of the
Confidential Information to anyone or any third party could cause monetary loss
and damages to the Company. The parties further agree that in the event of a
violation of this covenant against non-use and non-disclosure of Confidential

         11. DELIVERY OF DOCUMENTS UPON TERMINATION. The Employee shall deliver
to the Company or its designee at the termination of his employment all
correspondence, memoranda, notes, records, drawings, sketches, plans, customer
lists, product compositions, and other documents and all copies thereof, made,
composed or received by the Employee, solely or jointly with others, that are in
the Employee's possession, custody, or control at termination and that are
related in any manner to the past, present, or anticipated business or any
member of the Company Group. In this regard, the Employee hereby grants and

without limitation, the right to possess, print, copy, and sell or otherwise
dispose of, any reports, records, papers, summaries, photographs, drawings or
other documents, and writings, and copies, abstracts or summaries thereof, that
may be prepared by the Employee or under his direction or that may come into his
possession in any way during the term of his employment with the Company that
relate in any manner to the past, present or anticipated business of any member
of the Company Group.

         12. DISPUTES. The Company and Employee agree to the following in regard
to any disputes between them arising under any of the provisions of this
Agreement other than the provisions of Sections 8 through 11 hereof. Nothing in
this Section 12 applies to or governs disputes arising under Sections 8 through
11 of this Agreement.

                  (a) MEDIATION. The Company and Employee agree to mediate any
                  dispute arising under the applicable provisions of this
                  Agreement. In the event of any such dispute, the parties,
                  within thirty (30) days of a written request for mediation,
                  shall attend, in good faith, a mediation in order to make a
                  good faith reasonable effort to resolve such dispute arising
                  under this Agreement. The parties shall attempt, in good
                  faith, to agree to a mediator. If unable to so agree, the
                  parties, in that event, will move to arbitration as provided
                  in this Agreement and there will be no mediation. If this good
                  faith mediation effort fails to resolve any dispute arising
                  under this Agreement, the Company and Employee agree to
                  arbitrate any dispute arising under this Agreement. This
                  arbitration shall occur only after the mediation process
                  described herein.

                  (b) ARBITRATION. The Company and Employee agree, as concluded
                  by the parties to this Agreement on the advice of their
                  counsel, and as evidenced by the signatures of the parties and
                  of their respective attorneys, that all questions as to rights
                  and obligations arising under the terms of this Agreement are
                  subject to arbitration and such arbitration shall be governed
                  by the provisions of the Texas General Arbitration Act (Texas
                  Civil Practice and Remedies Code Section 171.001 et seq as it
                  may be amended from time to time).

                  (c) DEMAND FOR ARBITRATION. If a dispute should arise under
                  this Agreement, either party may within thirty (30) days make
                  a demand for arbitration by filing a demand in writing with
                  the other.

                  (d) APPOINTMENT OF ARBITRATORS. The parties to this Agreement
                  may agree on one arbitrator, but in the event that they cannot
                  so agree, there shall be three arbitrators, one named in
                  writing by each of the parties within thirty (30) days after
                  demand for arbitration is made, and a third to be chosen by
                  the two so named. The arbitrators among themselves shall
                  appoint a presiding arbitrator. Should either party fail to
                  timely join in the appointment of the arbitrators, the
                  arbitrators shall be appointed in accordance with the
                  provisions of Texas Civil Practice and Remedies Code Section
                  171.041.

                  (e) HEARING. All arbitration hearings conducted under the
                  terms of this Agreement, and all judicial proceedings to
                  enforce any of the provisions of this Agreement, shall take
                  place in Lubbock County, Texas. The hearing before the
                  arbitrators of the matter to be arbitrated shall be at the
                  time and place within that County selected by the arbitrators
                  or if deemed by the arbitrators to be more convenient for the
                  parties or more economically feasible, may be conducted in any
                  city within the Service Area as referred to in Section 7
                  hereof or within the State of Texas.

                  (f) ARBITRATION AWARD. If there is only one arbitrator, his or
                  her decision shall be binding and conclusive. The submission
                  of a dispute to the arbitrators and the rendering of their
                  decision shall be a condition precedent to any right of legal
                  action on the dispute. A judgment confirming the award of the
                  arbitrators may be rendered by any court having jurisdiction;
                  or the court may vacate, modify, or correct the award in
                  accordance with the provisions of the Texas General
                  Arbitration Act (Texas Civil Practice and Remedies Code
                  Section 171.087 et seq as it may be amended from time to
                  time).

                  (g) COSTS OF ARBITRATION. The costs and expenses of
                  arbitration, including the fees of the arbitrators but
                  excluding any attorneys' fees, shall be advanced by the
                  Company, but will ultimately be borne by the losing party or
                  in such proportions as the arbitrators shall determine.

                  (h) CONDUCT OF ARBITRATION. Any arbitration brought under the
                  terms of this Agreement shall be conducted in the following
                  manner:

                           (1) Time Limitations. The parties agree that the
                           following time limitations shall govern the
                           arbitration proceedings conducted under the terms of
                           this Agreement:

<PAGE>   15

                                    (a) Any demand for arbitration must be filed
                                    within thirty (30) days of the date the
                                    mediation is deemed unsuccessful, or thirty
                                    (30) days after the date of the written
                                    request for mediation, whichever is later.

                                    (b) Each party must select an arbitrator
                                    within thirty (30) days of receipt of notice
                                    that an arbitration proceeding has
                                    commenced. In the event that no such
                                    selection is made, the arbitrator selected
                                    by the other party may conduct the
                                    arbitration proceeding without selecting any
                                    other arbitrator.

                                    (c) The hearing must be held within sixty
                                    (60) days of the date on which the third
                                    arbitrator is selected.

                                    (d) Hearing briefs must be submitted no
                                    later than ten (10) days after the hearing.

                                    (e) The arbitration award must be made
                                    within thirty (30) days of the receipt of
                                    hearing briefs.

                           (2) Discovery in Arbitration Proceedings. The parties
                           agree that discovery may be conducted in the course
                           of the arbitration proceeding in accordance with the
                           following provisions:

                                    (a) Each party may notice no more than three
                                    (3) depositions in total, including both
                                    witnesses adherent to the adverse party and
                                    third-party witnesses.

                                    (b) Each party may serve no more than
                                    twenty-five (25) requests for admission on
                                    the other party. No requests may be served
                                    within ten (10) days of the date of hearing,
                                    unless the parties otherwise stipulate. All
                                    requests for admission shall be responded to
                                    within ten (10) days of service of the
                                    requests, unless the parties otherwise
                                    stipulate.

                                    (c) Each party may serve no more than fifty
                                    (50) interrogatories on the other party. No
                                    interrogatory shall contain subparts, or
                                    concern more than one topic or subject of
                                    inquiry. Interrogatories may not be phrased
                                    so as to circumvent the effect of this
                                    clause. No interrogatories may be served
                                    within ten (10) days of the date of hearing,
                                    unless the parties otherwise stipulate. All
                                    interrogatories shall be

                                    responded to within ten (10) days of service
                                    of the interrogatories, unless the parties
                                    otherwise stipulate.

                                    (d) Each party may serve no more than ten
                                    (10) requests for production of documents on
                                    the other party. No request for production
                                    of documents shall contain subparts, or seek
                                    more than one type of document. Requests for
                                    production of documents may not be phrased
                                    so as to circumvent the effect of this
                                    clause. Unless the parties otherwise
                                    stipulate, requests for production of
                                    documents may not be served within ten (10)
                                    day of the date of hearing, and all requests
                                    for production of documents shall be
                                    responded to within ten (10) days of service
                                    of the requests.

                                    (e) If any party contends that the other
                                    party has served discovery requests in a
                                    manner not permitted by this Section, or
                                    that the other party's response to a
                                    discovery request is unsatisfactory, the
                                    party may request the presiding arbitrator
                                    to resolve such discovery disputes. The
                                    presiding arbitrator shall prescribe the
                                    procedure by which such disputes are
                                    resolved. Any discovery dispute may be
                                    handled by telephone conference among the
                                    parties and the presiding arbitrator.

         13. SUCCESSORS; BINDING AGREEMENT; ASSIGNMENT. The Company shall
require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business or
assets of the Company to expressly assume and agree in writing to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession had taken place, provided that the
Employee must be given the position as the Chief Financial Officer ("CFO") with
the same authority, powers and responsibilities set forth in Section 1 hereof
with respect to the subsidiary or subdivision which operates the business of the
Company as it exists on the date of such business combination. Failure of the
Company to obtain such express assumption and agreement at or prior to the
effectiveness of any such succession shall be a breach of this Agreement and
shall entitle the Employee to compensation and benefits from the Company in the
same amount and on the same terms to which the Employee would be entitled
hereunder if the Company terminated the Employee's employment without Cause,
except that all options will be immediately vested. For purposes of implementing
the foregoing, the date on which any such succession becomes effective shall be
deemed the date of termination. As used in this Agreement, "Company" shall mean
the Company as hereinbefore defined and any successor to its business or assets
as aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise. The Company may not assign this Agreement, (i) except in
connection with, and to the

Employment Agreement       PAGE 16 OF 21

acquiror of, all or substantially all of the business or assets of the Company,
provided such acquiror expressly assumes and agrees in writing to perform this
Agreement as provided in this Section, and (ii) except in connection with the
Company becoming a wholly-owned subsidiary of Holdings, in which event the
Company may assign this Agreement and all of the Company's rights and
obligations hereunder to Holdings. The Employee may not assign his rights or
delegate his duties or obligations under this Agreement.

         14. NOTICE. Any notices or other communications required or permitted
to be given hereunder shall be in writing and shall be deemed to have been duly
made or given when hand delivered, one (1) business day after being transmitted
by telecopier (confirmed by mail) or sent by overnight courier against receipt,
or five (5) days after being mailed by registered or certified mail, postage
prepaid, return receipt requested, to the party to whom such communication is

                         SPRINT PCS MANAGEMENT AGREEMENT

         This SPRINT PCS MANAGEMENT AGREEMENT is made as of December 23, 1999,
between Sprint Spectrum L.P., a Delaware limited partnership, WirelessCo, L.P.,
a Delaware limited partnership, Cox Communications PCS, L.P., a Delaware limited
partnership, Cox CPS License, LLC, a Delaware limited liability company,
SprintCom, Inc., a Kansas corporation, and Alamosa PCS, LLC, a Delaware limited
liability company (but not any Related Party) ("Manager"). The definitions for
this agreement are set forth on the "Schedule of Definitions".

                                    RECITALS

         A. Sprint Spectrum L.P., a Delaware limited partnership, WirelessCo,
L.P., a Delaware limited partnership, SprintCom, Inc., a Kansas corporation,
American PCS Communications, LLC, a Delaware limited liability company, APC PCS,
LLC, a Delaware limited liability company, PhillieCo Partners I, L.P., a
Delaware limited partnership, PhillieCo, L.P., a Delaware limited partnership,
Cox Communications PCS, L.P., a Delaware limited partnership, and Cox PCS
License, L.L.C., a Delaware limited liability company, hold and exercise,
directly or indirectly, control over licenses to operate wireless services
networks.

         B. The entity or entities named in Recital A that execute this
agreement hold, directly or indirectly, the Licenses for the areas identified on
the Service Area Exhibit and are referred to in this agreement as "Sprint PCS."
Because this agreement addresses the rights and obligations of each license
holder with respect to each of its Licenses, each reference in this agreement to
"Sprint PCS" refers to the entity that owns, directly or indirectly, the License
referred to in that particular instance or application of the provision of this
agreement. If Sprint Spectrum does not own the License, it will provide on
behalf of Sprint PCS most or all of the services required under this agreement
to be provided by Sprint PCS.

         C. The Sprint PCS business was established to use the Sprint PCS
Network, a nationwide wireless services network, to offer seamless, integrated
voice and data services using wireless technology. The Sprint PCS Network offers
the services to customers under the Brands.

         D. This agreement, therefore, includes provisions defining Manager's
obligations with respect to:

         o        The design, construction and management of the Service Area
                  Network;

         o        Offering and promoting products and services designated by
                  Sprint PCS as the Sprint PCS Products and Services of the
                  Sprint PCS Network;

         o        Adherence to Program Requirements established by Sprint PCS to
                  ensure seamless interoperability throughout the Sprint PCS
                  Network and uniform and consistent quality of product and
                  service offerings;

         o        Adherence to Customer Service Program Requirements established
                  by Sprint PCS to ensure consistency in interactions with
                  customers (including billing, customer care, etc.); and

         o        Adherence to Program Requirements relating to the marketing,
                  promotion and distribution of Sprint PCS Products and
                  Services.

<PAGE>   8

         E. The Sprint PCS Network is expanding with the assistance of
"managers" (companies such as Manager that manage Service Area Networks that
offer Sprint PCS Products and Services under a license owned by Sprint PCS or
one of the entities named in Recital A) and "affiliates" (companies that manage
Service Area Networks that offer Sprint PCS Products and Services under a
license owned by the affiliate).

         F. Manager wishes to enter into this agreement to help construct,
operate, manage and maintain for Sprint PCS a portion of the Sprint PCS Network
in the Service Area. Sprint PCS has determined that permitting Manager to manage
a portion of the Sprint PCS Network in accordance with the terms of this
agreement will facilitate Sprint PCS' expansion of fully digital, wireless
coverage under the License and will enhance the wireless service for customers
of Sprint PCS.

         G. All managers of a portion of the business of Sprint PCS, including
Manager, must construct facilities and operate in accordance with Program
Requirements established by Sprint PCS with respect to certain aspects of the
development and offering of wireless products and services and the presentation
of the products and services to customers, to establish and operate the Sprint
PCS Network successfully by providing seamless, integrated voice and data
services, using wireless technology.

                                    AGREEMENT

         In consideration of the recitals and mutual covenants and agreements
contained in this agreement, the sufficiency of which are hereby acknowledged,
the parties, intending to be bound, agree as follows:

                                   1. MANAGER

         1.1 HIRING OF MANAGER. Sprint PCS hires Manager:

                  (a) to construct and manage the Service Area Network in
compliance with the License and in accordance with the terms of this agreement;

                  (b) to distribute continuously during the Term the Sprint PCS
Products and Services and to establish distribution channels in the Service
Area;

                  (c) to conduct continually during the Term advertising and
promotion activities in the Service Area (including mutual decisions to "go
dark", with respect to advertising and promotion activities, for reasonable
periods of time); and

                  (d) to manage that portion of the customer base of Sprint PCS
that has the NPA-NXXs assigned to the Service Area Network.

         Sprint PCS has the right to unfettered access to the Service Area
Network to be constructed by Manager under this agreement. The fee to be paid to
Manager by Sprint PCS under Section 10 is for all obligations of Manager under
this agreement.

         1.2 PROGRAM REQUIREMENTS. Manager must adhere to the Program
Requirements established by Sprint PCS and as modified from time to time, to
ensure uniform and consistent operation of all wireless systems within the
Sprint PCS Network and to present the Sprint PCS Products and Services to
customers in a uniform and consistent manner under the Brands.


                                        2
<PAGE>   9


         1.3 VENDOR PURCHASE AGREEMENTS. Manager may participate in discounted
volume-based pricing on wireless-related products and services and in the
warranties Sprint PCS receives from its vendors, as is commercially reasonable
and to the extent permitted by applicable procurement agreements (e.g.,
agreements related to network infrastructure equipment, subscriber equipment,
interconnection, and collocation). Sprint PCS will use commercially reasonable
efforts to obtain for managers the same price Sprint PCS receives from vendors;
this does not prohibit Sprint PCS from entering into procurement agreements that
do not provide managers with the Sprint PCS prices.

         Manager must purchase subscriber and infrastructure equipment from a
Sprint PCS approved list of products, which will include a selection from a
variety of manufacturers. Where required, the products must include proprietary
software developed by the manufacturers for Sprint PCS or by Sprint PCS to allow
seamless interoperability in the Sprint PCS Network. Sprint PCS or the vendor
may require Manager to execute a separate license agreement for the software
prior to Manager's use of the software.

         Manager may only make purchases under this Section 1.3 for items to be
used exclusively in the Service Area (e.g., Manager may not purchase base
stations under a Sprint PCS contract for use in a system not affiliated with
Sprint PCS).

         1.4 INTERCONNECTION. If Manager desires to interconnect a portion of
the Service Area Network with another carrier and Sprint PCS can interconnect
with that carrier at a lower rate, then to the extent permitted by applicable
laws, tariffs and contracts, Sprint PCS may arrange for the interconnection
under its agreements with the carrier and if it does so, Sprint PCS will bill
the interconnection fees to Manager.

         1.5 SEAMLESSNESS. Manager will design and operate its systems,
platforms, products and services in the Service Area and the Service Area
Network so as to seamlessly interface them into the Sprint PCS Network.

         1.6 FORECASTING. Manager and Sprint PCS will work cooperatively to
generate mutually acceptable forecasts of important business metrics including
traffic volumes, handset sales, subscribers and Collected Revenues for the
Sprint PCS Products and Services. The forecasts are for planning purposes only
and do not constitute Manager's obligation to meet the quantities forecast.

         1.7 FINANCING. The construction and operation of the Service Area
Network requires a substantial financial commitment by Manager. The manner in
which Manager will finance the build-out of the Service Area Network and provide
the necessary working capital to operate the business is described in detail on
Exhibit 1.7. Manager will allow Sprint PCS an opportunity to review before
filing any registration statement or prospectus or any amendment or supplement
thereto before distributing any offering memorandum or amendment or supplement
thereto, and agrees not to file or distribute any such document if Sprint PCS
reasonably objects in writing on a timely basis to any portion of the document
that refers to Sprint PCS, its Related Parties, their respective businesses,
this agreement or the Services Agreement.

         1.8 ETHICAL CONDUCT AND RELATED COVENANTS. Each party must perform its
obligations under this agreement in a diligent, legal, ethical, and professional
manner.

                             2. BUILD-OUT OF NETWORK


         2.1 BUILD-OUT PLAN. Manager will build-out the Service Area Network in
the Service Area in accordance with a Build-out Plan. Sprint PCS and Manager
will jointly develop each Build-out Plan, except the initial Build-out Plan and
any modifications, additions or expansions of the Build-out Plan will be subject
to prior written approval by Sprint PCS. Manager will report to Sprint PCS its
performance regarding the critical milestones included in the Build-out Plan on
a periodic basis as mutually agreed to by the parties, but no less frequently
than quarterly. The Build-out Plan and the Service Area Network as built must
comply with Sprint PCS Program Requirements and federal and local regulatory
requirements.

         Sprint PCS approves the Build-out Plan in effect as of the date of this
agreement, which Build-out Plan is attached as Exhibit 2.1. Each new or amended
Build-out Plan will also become part of Exhibit 2.1.

         2.2 COMPLIANCE WITH REGULATORY RULES. During the build-out of the
Service Area Network, Sprint PCS authorizes Manager to make all filings with
regulatory authorities regarding the build-out, including filings with the
Federal Aviation Administration, environmental authorities, and historical
districts. Manager may further delegate its duty under this Section 2.2 to a
qualified site acquisition company. Manager must ensure that a copy of every
filing is given to Sprint PCS. Manager must ensure that Sprint PCS is notified
in writing of any contact by a regulatory agency including the FCC with Manager
or Manager's site acquisition company regarding any filing. Sprint PCS has the
right to direct any proceeding, inquiry, dispute, appeal or other activity with
a regulatory or judicial authority regarding any filing made on behalf of Sprint
PCS. Manager will amend, modify, withdraw, refile and otherwise change any
filing as Sprint PCS requires. Notwithstanding the preceding sentences in this
Section 2.2, and in conjunction with Section 16, Sprint PCS is solely
responsible for making any and all filings with the FCC regarding the build-out.
Manager will notify Sprint PCS of any activity, event or condition related to
the build-out that might require an FCC filing.

         2.3 EXCLUSIVITY OF SERVICE AREA. Manager will be the only person or
entity that is a manager or operator for Sprint PCS with respect to the Service
Area and neither Sprint PCS nor any of its Related Parties will own, operate,
build or manage another wireless mobility communications network in the Service
Area so long as this agreement remains in full force and effect and there is no
Event of Termination that has occurred giving Sprint PCS the right to terminate
this agreement, except that:

                  (a) Sprint PCS may cause Sprint PCS Products and Services to
be sold in the Service Area through the Sprint PCS National Accounts Program
Requirements and Sprint PCS National or Regional Distribution Program
Requirements;

                  (b) A reseller of Sprint PCS Products and Services may sell
its products and services in the Service Area so long as such resale is not
contrary to the terms and conditions of this agreement; and

                  (c) Sprint PCS and its Related Parties may engage in the
activities described in Sections 2.4(a) and 2.4(b) with Manager in the
geographic areas within the Service Area in which Sprint PCS or any of its
Related Parties owns an incumbent local exchange carrier as of the date of this
agreement.

         2.4 RESTRICTION. In geographic areas within the Service Area in which
Sprint PCS or any of its Related Parties owns an incumbent local exchange
carrier as of the date of this agreement, Manager must not offer any Sprint PCS
Products or Services specifically designed for the competitive local exchange
market ("fixed wireless local loop"), except that:


                                        4
<PAGE>   11




                  (a) Manager may designate the local exchange carrier that is a
Related Party of Sprint PCS to be the exclusive distributor of the fixed
wireless local loop product in the territory served by the local exchange
carrier, even if a portion of its territory is within the Service Area; or

                  (b) Manager may sell the fixed wireless local loop product
under the terms and conditions specified by Sprint PCS (e.g., including
designation by Sprint PCS of an exclusive distribution agent for the territory).

This restriction exists with respect to a particular geographic area only so
long as Sprint PCS or its Related Party owns such incumbent local exchange
carrier.

         Nothing in this Section 2.4 prohibits Manager from offering Sprint PCS
Products and Services primarily designed for mobile functionality. The
restricted markets as of the date of this agreement are set forth on Exhibit
2.4.

         2.5 COVERAGE ENHANCEMENT. Sprint PCS and Manager agree that maintaining
a high standard of customer satisfaction regarding network capacity and
footprint is a required element of the manager and affiliate programs. Sprint
PCS intends to expand network coverage to build all cells that cover at least
5,000 pops and all interstate and major highways in the areas not operated by
Manager or Other Managers. Accordingly, Manager agrees to build-out New Coverage
when directed by Sprint PCS as set forth in this Section 2.5. Sprint PCS agrees
not to require any New Coverage build-out during the first two years of this
Agreement, nor any New Coverage that exceeds the capacity and footprint
parameters that Sprint PCS has adopted for all of its comparable markets.

         Sprint PCS will give to Manager a written notice of any New Coverage
within the Service Area that Sprint PCS decides should be built-out. Such notice
will include an analysis completed by Sprint PCS demonstrating that such
required build-out should be economically advantageous to Manager. Such analysis
will be generated in good faith and will be based on then-currently available
information, however Sprint PCS makes no warranties or representations regarding
the accuracy of, nor will Sprint PCS be bound by, or guarantee the accuracy of,
such analysis. Manager must confirm to Sprint PCS within 90 days after receipt
of the notice that Manager will build-out the New Coverage and deliver to Sprint
PCS with such confirmation Manager's proposed amendment to the Build-out Plan
and a description of the manner and timing in which it will finance such
build-out.

         If Manager confirms, within such 90-day period, its intention to
build-out the New Coverage, then Manager and Sprint PCS will diligently finalize
an amendment to the Build-out Plan and proceed as set forth in Sections 2.1 and
2.2. The amended Build-out Plan will contain critical milestones that provide
Manager a commercially reasonable period in which to construct and implement the
New Coverage. In determining what constitutes a "commercially reasonable period"
as used in this paragraph, the parties will consider several factors, including
local zoning processes and other legal requirements, weather conditions,
equipment delivery schedules, the need to arrange additional financing, and
other construction already in progress by Manager. Manager will construct and
operate the New Coverage in accordance with the terms of this Agreement, and the
New Coverage will be included in the Service Area Network for purposes of this
agreement.

         If Manager fails to confirm, within such 90-day period, its intention
to build-out the New Coverage, declines to complete such build-out, or fails to
complete such build-out in accordance with the amended Build- out Plan, then an
Event of Termination will be deemed to have occurred under Section 11.3.3,
Manager will

                                        5

<PAGE>   12


not have a right to cure such breach, and Sprint PCS may exercise its rights and
remedies under Section 11.2.2.1.

         Notwithstanding the preceding paragraphs in this Section 2.5, the
capacity and footprint parameters contained in the amended Build-out Plan will
not be required to exceed the parameters adopted by Sprint PCS in building out
all of its comparable service areas, unless such build-out relates to an
obligation regarding the Service Area Network mandated by law. When necessary
for reasons related to new technical standards, new equipment or strategic
reasons, Sprint PCS can require Manager to build-out the New Coverage
concurrently with Sprint PCS' build-out, in which case Sprint PCS will reimburse
Manager for its costs and expenses if Sprint PCS discontinues its related
build-out.

         If Sprint PCS requires build-out of New Coverage that will:

                  (a) cause the Manager to spend an additional amount greater
than 5% of Manager's shareholder's equity or capital account plus Manager's
long-term debt (i.e., notes that mature more than one year from the date
issued), as reflected on Manager's books; or

                  (b) cause the long-term operating expenses of Manager on a per
unit basis using a 10-year time frame to increase by more than 10% on a net
present value basis,

then Manager may give Sprint PCS a written notice requesting Sprint PCS to
reconsider the required New Coverage.

         The Sprint PCS Vice President or the designee of the Sprint PCS Chief
Officer in charge of the group that manages the Sprint PCS relationship with
Manager will review Manager's request and render a decision regarding the New
Coverage. If after the review and decision by the Vice President or designee,
Manager is still dissatisfied, then Manager may ask that the Chief Officer to
whom the Vice President or designee reports review the matter. If Sprint PCS
still requires Manager to complete the New Coverage following, the Chief
Officer's review, then if Manager and Sprint PCS fail to agree to an amended
Build-out Plan within 15 days after completion of the reconsideration process
described above in this paragraph or the end of the 90-day period described in
the second paragraph of this Section 2.5, whichever occurs first, then an Event
of Termination will be deemed to have occurred under Section 11.3.3, Manager
will not have a right to cure such breach, and Sprint PCS may exercise its
rights and remedies under Section 11.2.2.1.

         2.6 PURCHASE OF ASSETS BY MANAGER. If Sprint PCS has assets located in
the Service Area that Manager could reasonably use in its construction of the
Service Area Network and if Sprint PCS is willing to sell such assets, then
Manager agrees to purchase from Sprint PCS and Sprint PCS agrees to sell to
Manager the assets in accordance with the terms and conditions of the asset
purchase agreement attached as Exhibit 2.6.

         2.7 MICROWAVE RELOCATION. Sprint PCS will relocate interfering
microwave sources in the spectrum in the Service Area to the extent necessary to
permit the Service Area Network to carry the anticipated call volume as set out
in the Build-out Plan. If the spectrum cleared is not sufficient to carry the
actual call volume then Sprint PCS will clear additional spectrum of its
choosing to accommodate the call volume. Sprint PCS may choose to clear spectrum
one carrier at a time. The parties will share equally all costs associated with
clearing spectrum under this Section 2.7.


                                       6
<PAGE>   13


         2.8 DETERMINATION OF POPS. If any provision in this agreement requires
the determination of pops in a given area, then the pops will be determined
using the census block group pop forecast then used by Sprint PCS, except that a
different forecast will be used for any FCC filing and in preparing the
Build-out Plan if required by the FCC. Sprint PCS presently uses the forecast of
Equifax/NDS, but it may choose in its sole discretion to use another service
that provides comparable data.

                     3. PRODUCTS AND SERVICES; IXC SERVICES

         3.1 SPRINT PCS PRODUCTS AND SERVICES. Manager must offer for sale,
promote and support all Sprint PCS Products and Services within the Service
Area, unless the parties otherwise agree in advance in writing. Within the
Service Area, Manager may only sell, promote and support wireless products and
services that are Sprint PCS Products and Services or are other products and
services authorized under Section 3.2. The Sprint PCS Products and Services as
of the date of this agreement are attached as Exhibit 3.1. Sprint PCS may modify
the Sprint PCS Products and Services from time to time in its sole discretion by
delivering, to Manager a new Exhibit 3.1. If Sprint PCS begins offering
nationally a Sprint PCS Product or Service that is a Manager's Product or
Service, such Manager's Product or Service will become a Sprint PCS Product or
Service under this agreement.

         3.2 OTHER PRODUCTS AND SERVICES. Manager may offer wireless products
and services that are not Sprint PCS Products and Services, on the terms Manager
determines, if the offer of the additional products and services:

                  (a) does not violate the obligations of Manager under this
         agreement;

                  (b) does not cause distribution channel conflict with or
         consumer confusion regarding Sprint PCS' regional and national
         offerings of Sprint PCS Products and Services;

                  (c) complies with the Trademark License Agreements; and

                  (d) does not materially impede the development of the Sprint
         PCS Network.

         Manager will not offer any products or services under this Section 3.2
that are confusingly similar to Sprint PCS Products and Services. Manager must
request that Sprint PCS determine whether Sprint PCS considers a product or
service to be confusingly similar to any Sprint PCS Products and Services by
providing advance written notice to Sprint PCS that describes those products and
services that could be interpreted to be confusingly similar to Sprint PCS
Products and Services. If Sprint PCS fails to provide a response to Manager
within 30 days after receiving the notice, then the products and services are
deemed to create confusion with the Sprint PCS Products and Services and the
request therefore rejected. In rejecting any request Sprint PCS must provide the
reasons for the rejection. If the rejection is based on Sprint PCS' failure to
respond within 30 days and Manager requests an explanation for the deemed
rejection, then Sprint PCS must provide within 30 days the reasons for the
rejection.

         3.3 CROSS-SELLING WITH SPRINT. Manager and Sprint and Sprint's Related
Parties may enter into arrangements to sell Sprint's services, including long
distance service (except those long distance services governed by Section 3.4),
Internet access, customer premise equipment, prepaid phone cards, and any other
services that Sprint or its Related Parties make available from time to time.
Sprint's services may be packaged with the Sprint PCS Products and Services.


                                        7
<PAGE>   14


         If Manager chooses to resell the long distance services, Internet
access or competitive local telephone services including prepaid phone cards, of
third parties (other than Manager's Related Parties), Manager will give Sprint
the right of last offer to provide those services on the same terms and
conditions as the offer to which Manager is prepared to agree, subject to the
terms of any existing agreements Manager was subject to prior to execution of
this agreement.

         If Sprint sells Sprint PCS Products and Services in the Service Area,
Manager will provide such Sprint PCS Products and Services to such customers in
accordance with the terms and conditions of the Sprint PCS National or Regional
Distribution Program Requirements.

         3.4 IXC SERVICES. Manager must purchase from Sprint long distance
telephony services for the Sprint PCS Products and Services at wholesale rates.
Long distance telephone calls are those calls between the local calling area for
the Service Area Network and areas outside the local calling area. The local
calling area will be defined by mutual agreement of Sprint PCS and Manager. If
the parties cannot agree on the extent of the local calling area they will
resolve the matter through the dispute resolution process in Section 14. Any
arrangement must have terms at least as favorable to Manager (in all material
respects) as those offered by Sprint to any wholesale customer of Sprint in
comparable circumstances (taking into consideration volume, traffic patterns,
etc.). If Manager is bound by an agreement for these services and the agreement
was not made in anticipation of this agreement, then the requirements of this
Section 3.4 do not apply during the term of the other agreement. If the other
agreement terminates for any reason then the requirements of this Section 3.4 do
apply.

         3.5 RESALE OF PRODUCTS AND SERVICES.

                  3.5.1 MANDATORY RESALE OF PRODUCTS AND SERVICES. Sprint PCS is
subject to FCC rules that require it to allow its service plans to be resold by
a purchaser of the service plan. Sprint PCS will not grant the purchaser of a
service plan the right to use any of the support services offered by Sprint PCS,
including customer care, billing, collection, and advertising, nor the right to
use the Brands. The reseller only has the right to use the service purchased.
Consequently, Manager agrees not to interfere with any purchaser of the Sprint
PCS Products or Services who resells the service plans in accordance with this
agreement and applicable law. Manager will notify purchaser that the purchaser
does not have a right to use the Brands or Sprint PCS' support services. In
addition, Manager will notify Sprint PCS if it reasonably believes a reseller of
retail service plans is using the support services or Brands.

                  3.5.2 VOLUNTARY RESALE OF PRODUCTS AND SERVICES. Sprint PCS
may choose to offer a resale product under which resellers will resell Sprint
PCS Products and Services under brand names other than the Brands, except Sprint
PCS may permit the resellers to use the Brands for limited purposes related to
the resale of Sprint PCS Products and Services (e.g., to notify people that the
handsets of the resellers will operate on the Sprint PCS Network). The resellers
may also provide their own support services (e.g., customer care and billing) or
may purchase the support services from Sprint PCS.

         If Sprint PCS chooses to offer a voluntary resale product, it will
adopt a program that will be a Program Requirement under this agreement and that
addresses the manner in which Manager and Other Managers interact with the
resellers. Manager must agree to comply with the terms of the program, including
its pricing provisions, if Manager wants handsets of subscribers of resellers
with NPA-NXXs of Manager to be activated. Usage of telecommunications services
while in the Service Area by subscribers of resellers with

                                        8

<PAGE>   15


NPA-NXXs from outside the Service Area will be subject to the pricing provisions
of the Sprint PCS Roaming and Inter Service Area Program for roaming and inter
service area pricing between Manager and Sprint PCS unless Manager agrees in
writing to different pricing.

         Except as required under the regulations and rules concerning mandatory
resale, Manager may not sell Sprint PCS Products and Services for resale unless
Sprint PCS consents to such sales in advance in writing.

         3.6 NON-COMPETITION. Neither Manager nor any of its Related Parties may
offer Sprint PCS Products and Services outside of the Service Area without the
prior written approval of Sprint PCS.

         Within the Service Area, Manager and Manager's Related Parties may
offer, market or promote telecommunications products or services only under the
following brands:

                  (a) products or services with the Brands;

                  (b) other products and services approved under Section 3.2;

                  (c) products or services with Manager's brand; or

                  (d) products or services with the brands of Manager's Related
Parties,

except no brand of a significant competitor of Sprint PCS or its Related Parties
in the telecommunications business may be used by Manager or Manager's Related
Parties on these products and services.

         If Manager or any of its Related Parties has licenses to provide
broadband personal communication services outside the Service Area, neither
Manager nor such Related Party may utilize the spectrum to offer Sprint PCS
Products and Services without prior written consent from Sprint PCS.
Additionally, when Manager's customers from inside the Service Area travel or
roam to other geographic areas, Manager will route the customers' calls, both
incoming and outgoing, according to the Sprint PCS Network Roaming and Inter
Service Area Program Requirements, without regard to any wireless networks
operated by Manager or its Related Parties. For example, Manager will program
the preferred roaming list for handsets sold in the Service Area to match the
Sprint PCS preferred roaming list.

         3.7 RIGHT OF LAST OFFER. Manager will offer to Sprint the right to make
to Manager the last offer to provide backhaul and transport services for call
transport for the Service Area Network, if Manager decides to use third parties
for backhaul and transport services rather than self-provisioning the services
or purchasing the services from Related Parties of Manager. Sprint will have a
reasonable time to respond to Manager's request for last offer to provide
backhaul and transport pricing and services, which will be no greater than 5
Business Days after receipt of the request for the services and pricing from
Manager.

         If Manager has an agreement in effect as of the date of this agreement
for these services and the agreement was not made in anticipation of this
agreement, then the requirements of this Section 3.7 do not apply during the
term of the other agreement. If the other agreement terminates for any reason
then the requirements of this Section 3.7 do apply.

         4.1 SPRINT PCS NATIONAL OR REGIONAL DISTRIBUTION PROGRAM REQUIREMENTS.
During the term of this agreement, Manager must participate in any Sprint PCS
National or Regional Distribution Program (as in effect from time to time), and
will pay or receive compensation for its participation in accordance with the
terms and conditions of that program. The Sprint PCS National or Regional
Distribution Program Requirements in effect as of the date of this agreement are
attached as Exhibit 4.1.

                  4.1.1 TERRITORIAL LIMITATIONS ON MANAGER'S DISTRIBUTION
ACTIVITIES. Neither Manager nor any of its Related Parties will market, sell or
distribute Sprint PCS Products and Services outside of the Service Area, except:

                  (a) as otherwise agreed upon by the parties in advance in
writing; or

                  (b) Manager may place advertising in media that has
distribution outside of the Service Area, so long as that advertising is
intended by Manager to reach primarily potential customers within the Service
Area.

                  4.1.2 SETTLEMENT OF EQUIPMENT SALES. Sprint PCS will establish
a settlement policy and process that will be included in the Sprint PCS National
or Regional Distribution Program Requirements to:

                  (a) reconcile sales of subscriber equipment made in the
service areas of Sprint PCS or Other Managers of Sprint PCS, that result in
activations in the Service Area; and

                  (b) reconcile sales of subscriber equipment made in the
Service Area that result in activations in service areas of Sprint PCS or Other
Managers.

         In general, the policy will provide that the party in whose service
area the subscriber equipment is activated will be responsible for the payment
of any subsidy (i.e., the difference between the price paid to the manufacturer
and the suggested retail price for direct channels or the difference between the
price paid to the manufacturer and the wholesale price for third party
retailers) and for other costs associated with the sale, including logistics,
inventory carrying costs, direct channel commissions and other retailer
compensation.

                  4.1.3 USE OF THIRD-PARTY DISTRIBUTORS.

                  (a) Manager may request that Sprint PCS and a local
distributor enter into Sprint PCS' standard distribution agreement regarding the
purchase from Sprint PCS of handsets and accessories. Sprint PCS will use
commercially reasonable efforts to reach agreement with the local distributor.
Sprint PCS may refuse to enter into a distribution agreement with a distributor
for any reasonable reason, including that the distributor fails to pass Sprint
PCS' then current credit and background checks or the distributor fails to agree
to the standard terms of the Sprint PCS distribution agreement. Any local
distributor will be subject to the terms of the Trademark License Agreements or
their equivalent. Manager will report to Sprint PCS the activities of any local
distributor that Manager believes to be in violation of the distribution
agreement.

                  (b) Manager may establish direct local distribution programs
in accordance with the Sprint PCS National or Regional Distribution Program
Requirements, subject to the terms and conditions of the Trademark License
Agreements and the non-competition and other provisions contained in this

         a particular distributor,

                           (ii) Manager is responsible for such distributor's
         compliance with the terms of the Trademark License Agreements and the
         other provisions contained in this agreement, and

                           (iii) Manager must retain the right to terminate the
         distribution rights of the local distributor when so instructed by
         Sprint PCS (even if Sprint PCS initially approved or did not exercise
         its right to review the distributor).

         4.2 SPRINT PCS NATIONAL ACCOUNTS PROGRAM REQUIREMENTS. During the term
of this agreement, Manager must participate in the Sprint PCS National Accounts
Program (as in effect from time to time), and will be entitled to compensation
for its participation and will be required to pay the expenses of the program in
accordance with the terms and conditions of that program. The Sprint PCS
National Accounts Program Requirements in effect as of the date of this
agreement are attached as Exhibit 4.2.

         4.3 SPRINT PCS ROAMING AND INTER SERVICE AREA PROGRAM REQUIREMENTS.
Manager will participate in the Sprint PCS Roaming and Inter Service Area
Program established and implemented by Sprint PCS, including roaming price plans
and inter-carrier settlements. The Sprint PCS Roaming and Inter Service Area
Program Requirements in effect as of the date of this agreement are attached as
Exhibit 4.3.

         As part of the Sprint PCS Roaming and Inter Service Area Program
Requirements, Sprint PCS will establish a settlement policy and process to
equitably distribute between the members making up the Sprint PCS Network (i.e.,
Sprint PCS, Manager and all Other Managers) the revenues received by one member
for services used by its customers when they travel into other members' service
areas.

         4.4 PRICING. Manager will offer and support all Sprint PCS pricing
plans designated for regional or national offerings of Sprint PCS Products and
Services (e.g., national inter service area rates, regional home rates, and
local price points). The Sprint PCS pricing plans as of the date of this
agreement are attached as Exhibit 4.4. Sprint PCS may modify the Sprint PCS
pricing plans from time to time in its sole discretion by delivering to Manager
a new Exhibit 4.4.

         Additionally, with prior approval from Sprint PCS, which approval will
not be unreasonably withheld, Manager may establish price plans for Sprint PCS
Products and Services that are only offered in its local market, subject to:

                           (a) the non-competition and other provisions
contained in this agreement;

                           (b) consistency with regional and national pricing
plans;

                           (c) regulatory requirements; and

                           (d) capability and cost of implementing rate plans in
Sprint PCS systems (if used).

         Manager must provide advance written notice to Sprint PCS with details
of any pricing proposal for Sprint PCS Products or Services in the Service Area.
If Sprint PCS fails to. respond to Manager within 10 Business Days after
receiving such notice, then the price proposed for those Sprint PCS Products or
Services is deemed approved.

                                       11

<PAGE>   18


         At the time Sprint PCS approves a pricing proposal submitted by
Manager, Sprint PCS will provide Manager an estimate of the costs and expenses
and applicable time frames required for Sprint PCS to implement the proposed
pricing plan. Manager agrees to promptly reimburse Sprint PCS for any cost or
expense incurred by Sprint PCS to implement such a pricing plan, which will not
exceed the amount estimated by Sprint PCS if Manager waited for Sprint PCS'
response to Manager's proposal.

         4.5 HOME SERVICE AREA. Sprint PCS and Manager will agree to the initial
home service area for each base station in the Service Area Network prior to the
date the Service Area Network goes into commercial operation. If the parties
cannot agree to the home service area for each base station in the Service Area
Network, then the parties will use the dispute resolution process in Section 14
of this agreement to assign each base station to a home service area.

                                5. USE OF BRANDS

         5.1 USE OF BRANDS.

                  (b) Manager must use the Brands exclusively in the marketing,
promotion, advertisement, distribution, lease or sale of any Sprint PCS Products

extent permitted by the Trademark License Agreements and not inconsistent with
the terms of this agreement.

                  (c) Neither Manager nor any of its Related Parties may market,
promote, advertise, distribute, lease or sell any of the Sprint PCS Products and
Services or Manager's Products and Services on a non-branded, "private label"
basis or under any brand, trademark, trade name or trade dress other than the
Brands, except (i) for sales to resellers required under this agreement, or (ii)
as permitted under the Trademark License Agreements.

                  (d) The provisions of this Section 5.1 do not prohibit Manager
from including Sprint PCS Products and Services under the Brands within the
Service Area as part of a package with its other products and services that bear
a different brand or trademark. The provisions of this Section 5.1 do not apply
to the extent that they are inconsistent with applicable law or in conflict with
the Trademark License Agreements.

         5.2 CONFORMANCE TO MARKETING COMMUNICATIONS GUIDELINES. Manager must
conform to the Marketing Communications Guidelines in connection with the
marketing, promotion, advertisement, distribution, lease and sale of any of the
Sprint PCS Products and Services. The Marketing Communications Guidelines in

<PAGE>   19


to time during the term of this agreement with respect to the Sprint PCS
Products and Services, except that Manager may engage in the joint marketing
activities only if the joint marketing activities:

                           (i) are conducted in accordance with the terms and
         conditions of the Trademark License Agreements and the Marketing
         Communications Guidelines;

                           (ii) do not violate the terms of this agreement;

                           (iii) are not likely (as determined by Sprint PCS, in
         its sole discretion) to cause confusion between the Brands and any
         other trademark or service mark used in connection with the activities;

                           (iv) are not likely (as determined by Sprint, in its
         sole discretion) to cause confusion between the Sprint Brands and any

         Products and Services are being advertised, marketed or promoted under

         in the Trademark License Agreements. Manager will not engage in any
         activity that includes co-branding involving use of the Brands (that
         is, the marketing, promotion, advertisement, distribution, lease or
         sale of any of the Sprint PCS Products and Services under the Brands
         and any other trademark or service mark), except as provided in the
         Trademark License Agreements.

                  (b) Manager must provide advance written notice to Sprint PCS
describing any joint marketing activities that may:

                           (i) cause confusion between the Brands and any other
         trademark or service mark used in connection with the proposed
         activities; or

                           (ii) give rise to the perception that the Sprint PCS
         Products and Services are being advertised, marketed or promoted under
         any trademark or service mark other than the Brands, except as provided
         in the Trademark License Agreements.

                  (c) If Sprint PCS fails to provide a response to Manager
within 20 days after receiving such notice, then the proposed activities are
deemed, as the case may be:

                           (i) not to create confusion between the Brands and
         any other trademark or service mark; or

                           (ii) not to give rise to the perception that
         Manager's products and services are being advertised, marketed or
         promoted under any trademark or service mark other than the Brands,
         except as provided in the Trademark License Agreements.

         5.4 PRIOR APPROVAL OF USE OF BRANDS. Manager must obtain advance
written approval from Sprint for use of the Sprint Brands to the extent required

         6.2 IN-TERRITORY ADVERTISING AND PROMOTION. Manager must advertise and

unit handset sales.

         Sprint PCS has the right to use in any promotion or advertising done by

reimburse Manager for the reproduction costs related to such use.

         Sprint PCS will make available to Manager the promotion or advertising

Products and Services in current use by Sprint PCS (e.g., radio ads, television
ads, design of print ads, design of point of sale materials, retail store
concepts and designs, design of collateral). Manager will bear the cost of using
such materials (e.g., cost of local radio and television ad placements, cost of
printing collateral in quantity, and building out and finishing retail stores).

         6.3 REVIEW OF ADVERTISING AND PROMOTION CAMPAIGNS. Sprint PCS and
Manager will jointly review the upcoming marketing and promotion campaigns of
Manager with respect to Sprint PCS Products and Services (including advertising
and promotion expense budgets) and will use good faith efforts to coordinate

both parties. Sprint PCS and Manager may engage in cooperative advertising or
promotional activities during the term of this agreement as the parties may
agree in writing.

                  7. SPRINT PCS TECHNICAL PROGRAM REQUIREMENTS

         7.1 CONFORMANCE TO SPRINT PCS TECHNICAL PROGRAM REQUIREMENTS.

                  (a) Manager must meet or exceed the Sprint PCS Technical
Program Requirements established by Sprint PCS from time to time for the Sprint
PCS Network Manager will be deemed to meet the Sprint PCS Technical Program
Requirements if:

                           (i) Manager operates the Service Area Network at a
         level equal to or better than the lower of the Operational Level of
         Sprint PCS or the operational level contemplated by the Sprint PCS
         Technical Program Requirements; or

                           (ii) Sprint PCS is responsible under the Services
         Agreement to ensure the Service Area Network complies with the Sprint
         PCS Technical Program Requirements.

                  (b) Manager must demonstrate to Sprint PCS that Manager has
complied with the Sprint PCS Technical Program Requirements prior to connecting
the Service Area Network to the rest of the Sprint PCS Network. Once the Service
Area Network is connected to the Sprint PCS Network, Manager must continue to
comply with the Sprint PCS Technical Program Requirements. Sprint PCS agrees
that the Sprint PCS Technical Program Requirements adopted for Manager will be
the same Sprint PCS Technical Program Requirements applied by Sprint PCS to the
Sprint PCS Network.

         7.2 ESTABLISHMENT OF SPRINT PCS TECHNICAL PROGRAM REQUIREMENTS. Sprint
PCS has delivered to Manager a copy of the current Sprint PCS Technical Program
Requirements, attached as Exhibit 7.2. Sprint PCS drafted the Sprint PCS
Technical Program Requirements to ensure a minimum, base-line level of quality
for the Sprint PCS Network. The Sprint PCS Technical Program Requirements
include standards relating to voice quality, interoperability, consistency
(seamlessness) of coverage, RF design parameters, system design, capacity, and
call blocking ratio. Sprint PCS has selected code division multiple access as
the initial air interface technology for the Sprint PCS Network (subject to
change in accordance with Section 9.1).

         7.3 HANDOFF TO ADJACENT NETWORKS. If technically feasible and
commercially reasonable, Manager will operate the Service Area Network in a
manner that permits a seamless handoff of a call initiated on the Service Area
Network to any adjacent PCS network that is part of the Sprint PCS Network, as
specified in the Sprint PCS Technical Program Requirements. Sprint PCS agrees
that the terms and conditions for seamless handoffs adopted for the Service Area
Network will be the same as the terms Sprint PCS applies to the other parts of
the Sprint PCS Network for similar configurations of equipment.

               8. SPRINT PCS CUSTOMER SERVICE PROGRAM REQUIREMENTS

         8.1 COMPLIANCE WITH SPRINT PCS CUSTOMER SERVICE PROGRAM REQUIREMENTS.
Manager must comply with the Sprint PCS Customer Service Program Requirements in
providing the Sprint PCS Products and Services to any customer of Manager,
Sprint PCS or any Sprint PCS Related Party. Manager will be deemed to meet the
standards if:


                                       15
<PAGE>   22


                  (a) Manager operates the Service Area Network at a level equal
to or better than the lower of the Operational Level of Sprint PCS or the
operational level contemplated by the Program Requirements; or

                  (b) Manager has delegated to Sprint PCS under the Services
Agreement responsibility to ensure the Service Area Network complies with the
Sprint PCS Customer Service Standards.

         Sprint PCS has delivered to Manager a copy of the Sprint PCS Customer
Service Standards, which are attached as Exhibit 8.1.

                       9. SPRINT PCS PROGRAM REQUIREMENTS

         9.1 PROGRAM REQUIREMENTS GENERALLY. This agreement contains numerous
references to Sprint PCS National and Regional Distribution Program
Requirements, Sprint PCS National Accounts Program Requirements, Sprint PCS
Roaming and Inter Service Area Program Requirements, Sprint PCS Technical
Program Requirements and Sprint PCS Customer Service Program Requirements. This
agreement also provides under Section 3.5.2 for the offering by Sprint PCS of a
voluntary resale product through a program, which program, if adopted, will be a
Program Requirement under this agreement. Sprint PCS may unilaterally amend from
time to time in the manner described in Section 9.2 all Program Requirements
mentioned in this agreement. The most current version of the Program
Requirements mentioned in the first sentence of this Section 9.1 have been
provided to Manager. Manager has reviewed the Program Requirements and adopts
them for application in the Service Area.

         9.2 AMENDMENTS TO PROGRAM REQUIREMENTS. Sprint PCS may amend any of the
Program Requirements, subject to the following conditions:

                  (a) The applicable Program Requirements, as amended, will
apply equally to Manager, Sprint PCS and each Other Manager, except if Manager
and Sprint PCS agree otherwise or if Sprint PCS grants a waiver to Manager.
Sprint PCS may grant waivers to Other Managers without affecting Manager's
obligation to comply with the Program Requirements;

                  (b) Each amendment will be reasonably required to fulfill the
purposes set forth in Section 1.2 with respect to uniform and consistent
operations of the Sprint PCS Network and the presentation of Sprint PCS Products
and Services to customers in a uniform and consistent manner;

                  (c) Each amendment will otherwise be on terms and conditions
that are commercially reasonable with respect to the construction, operation and
management of the Sprint PCS Network. With respect to any amendment to the
Program Requirements, Sprint PCS will provide for reasonable transition periods
and, where appropriate, may provide for grandfathering provisions for existing
activities by Manager that were permitted under the applicable Program
Requirements before the amendment;

                  (d) Sprint PCS must give Manager reasonable, written notice of
the amendment, but in any event the notice will be given at least 30 days prior
to the effective date of the amendment; and

                  (e) Manager must implement any changes in the Program
Requirements within a commercially reasonable period of time unless otherwise
consented to by Sprint PCS. Sprint PCS will determine what constitutes a
commercially reasonable period of time taking into consideration relevant
business

                                       16

<PAGE>   23


factors, including the strategic significance of the changes to the Sprint PCS
Network, the relationship of the changes to the yearly marketing cycle, and the
financial demands on and capacity generally of Other Managers. Notwithstanding
the preceding two sentences, Manager will not be required to implement any
change in the Service Area Network or the business of Manager required by an
amendment to a Program Requirement until Sprint PCS has implemented the required
changes in substantially all of that portion of the Sprint PCS Network that
Sprint PCS operates without the use of a manager or affiliate, unless the
amendment to the Program Requirement relates to an obligation regarding the
Service Area Network mandated by law. When necessary for reasons related to new
technical standards, new equipment or strategic reasons, Sprint PCS can require
Manager to implement the changes in the Service Area Network or Manager's
business concurrently with Sprint PCS, in which case Sprint PCS will reimburse
Manager for its costs and expenses if Sprint PCS discontinues the Program
Requirement changes prior to implementation.

         Sprint PCS may grant Manager appropriate waivers and variances from the
requirements of any Program Requirements. Sprint PCS has the right to adopt any
Program Requirements that implement any obligation regarding the Service Area
Network mandated by law.

         Any costs and expenses incurred by Manager in connection with
conforming to any change to the Program Requirements during the term of this
agreement are the responsibility of Manager.

         9.3 MANAGER'S RIGHT TO REQUEST REVIEW OF CHANGES. If Sprint PCS
announces a change to a Program Requirement that will:

                  (a) cause the Manager to spend an additional amount greater
than 5% of Manager's shareholder's equity or capital account plus Manager's
long-term debt (i.e., notes that mature more than one year from the date
issued), as reflected on Manager's books; or

                  (b) cause the long term operating expenses of Manager on a per
unit basis using a 10-year time frame to increase by more than 10% on a net
present value basis,

then Manager may give Sprint PCS a written notice requesting Sprint PCS to
reconsider the change.

         The Sprint PCS Vice President or the designee of the Sprint PCS Chief
Officer in charge of the group that manages the Sprint PCS relationship with
Manager will review Manager's request and render a decision regarding the
change. If after the review and decision by the Vice President or designee,
Manager is still dissatisfied, then Manager may ask that the Chief Officer to
whom the Vice President or designee reports review the matter. If Sprint PCS
still requires Manager to implement the change to the Program Requirement
following, the Chief Officer's review, then upon Manager's failure to implement
the change an Event of Termination will be deemed to have occurred under Section
11.3.3, Manager will not have a right to cure such breach, and Sprint PCS may
exercise its rights and remedies under Section 11.6.

         9.4 SPRINT PCS' RIGHT TO IMPLEMENT CHANGES. If Manager requests Sprint
PCS to reconsider a change to a Program Requirement as permitted under Section
9.3 and Sprint PCS decides it will not require Manager to make the change,
Sprint PCS may, but is not required to, implement the change at Sprint PCS'
expense, in which event Manager will be required to operate the Service Area
Network, as changed, but Sprint PCS will be entitled to any revenue derived from
the change.

         9.5 RIGHTS OF INSPECTION. Sprint PCS and its authorized agents and
representatives may enter upon the premises of any office or facility operated
by or for Manager at any time, with reasonable advance notice to Manager if
possible, to inspect, monitor and test in a reasonable manner the Service Area
Network, including the facilities, equipment, books and records of Manager, to
ensure that Manager has complied or is in compliance with all covenants and
obligations of Manager under this agreement, including Manager's obligation to
conform to the Program Requirements. The inspection, monitoring and testing may
not disrupt the operations of the office or facility, nor impede Manager's
access to the Service Area Network.

         9.6 MANAGER'S RESPONSIBILITY TO INTERFACE WITH SPRINT PCS. Manager will
use platforms fully capable of interfacing with the Sprint PCS platforms in
operating the Service Area Network and in providing Sprint PCS Products and
Services. Manager will pay the expense of making its platforms fully capable of
interfacing with Sprint PCS, including paying for the following:

                           (i) connectivity;

                           (ii) any changes that Manager requests Sprint PCS to
         make to Sprint PCS systems to interconnect with Manager's systems that
         Sprint PCS, in its sole discretion, agrees to make;

                           (iii) equipment to run Manager's software;

                           (iv) license fees for Manager's software; and

                           (v) Manager's upgrades or changes to its platforms.

                                    10. FEES

         10.1 FEES AND PAYMENTS.

                  10.1.1 FEE BASED ON COLLECTED REVENUES. Sprint PCS will pay to
Manager a weekly fee equal to 92% of Collected Revenues for the week for all
obligations of Manager under this Agreement. The fee will be due on Thursday of
the week following the week for which the fee is calculated.

                  10.1.2 PAYMENT OF UNIVERSAL SERVICE FUNDS. Sprint PCS and
Manager will share any federal and state subsidy funds (e.g., payments by a
state of universal service fund subsidies to Sprint PCS or Manager), if any,
received by Sprint PCS or Manager for customers who reside in the portion of the
Service Area served by the Service Area Network. Manager is entitled to 92% of
any amount received by either party and Sprint PCS is entitled to 8% of such
amounts.

                  10.1.3 INTER SERVICE AREA FEES. Sprint PCS will pay to Manager
monthly a fee as set out in the Sprint PCS Roaming and Inter Service Area
Program, for each minute of use that a customer of Sprint PCS or one of the
Other Managers whose NPA-NXX is not assigned to the Service Area Network uses
the Service Area Network. Manager will pay to Sprint PCS a fee, as set out in
the Sprint PCS Roaming and Inter Service Area Program, for each minute of use
that a customer whose NPA-NXX is assigned to the Service Area Network uses a
portion of the Sprint PCS Network other than the Service Area Network. Manager
acknowledges that the manner in which the NPA-NXX is utilized could change,
which will require a modification in the manner in which the inter service area
fees, if any, will be calculated.


                                       18

                  10.1.4 INTERCONNECT FEES. Manager will pay to Sprint PCS (or
to other carriers as appropriate) monthly the interconnect fees, if any, as
provided under Section 1.4.

                  10.1.5 OUTBOUND ROAMING FEES. If not otherwise provided under
any Program Requirement:

                  (a) Sprint PCS will pay to Manager monthly the amount of
Outbound Roaming fees that Sprint PCS collects for the month from end users
whose NPA-NXX is assigned to the Service Area; and

                  (b) Manager will pay to Sprint PCS (or to a clearinghouse or
other carrier as appropriate) the direct cost of providing the capability for
the Outbound Roaming, including any amounts payable to the carrier that handled
the roaming call and the clearinghouse operator.

                  10.1.6 REIMBURSEMENTS. Manager will pay to or reimburse Sprint
PCS for any amounts that Sprint PCS is required to pay to a third party (e.g., a
telecommunications carrier) to the extent Sprint PCS already paid such amount to
Manager under this Section 10.

         10.2 MONTHLY TRUE UP. Manager will report to Sprint PCS monthly the
amount of Collected Revenues received directly by the Manager (e.g., customer
mails payment to the business address of Manager rather than to the lockbox or a
customer pays a direct sales force representative in cash). Sprint PCS will on a
monthly basis true up the fees and payments due under Section 10.1 against the
actual payments made by Sprint PCS to Manager. Sprint PCS will provide to
Manager a true up report each month showing the true up and the net amount due
from one party to the other, if any. If the weekly payments made to Manager
exceed the actual fees and payments due to Manager, then Manager will remit the
amount of the overpayment to Sprint PCS within 5 Business Days after receiving
the true up report from Sprint PCS. If the weekly payments made to Manager are
less than the actual fees and payments due to Manager, then Sprint PCS will
remit the shortfall to Manager within 5 Business Days after sending the true up
report to Manager.

         If a party disputes any amount on the true up report, the disputing
party must give the other party written notice of the disputed amount and the
reason for the dispute within 90 days after it receives the true up report. The
dispute will be resolved through the dispute resolution process in Section 14.
The parties must continue to pay to the other party any undisputed amounts owed
under this agreement during the dispute resolution process. The dispute of an
item does not stay or diminish a party's other rights and remedies under this
agreement.

         10.3 TAXES. Manager will pay or reimburse Sprint PCS for any sales,
use, gross receipts or similar tax, administrative fee, telecommunications fee
or surcharge for taxes or fees levied by a governmental authority on the fees
and charges payable by Sprint PCS to Manager.

         Manager will report all taxable property to the appropriate taxing
authority for ad valorem tax purposes. Manager will pay as and when due all
taxes, assessments, liens, encumbrances, levies, and other charges against the
real estate and personal property owned by Manager or used by Manager in
fulfilling its obligations under this agreement.

         Manager is responsible for paying all sales, use, or similar taxes on
the purchase and use of its equipment, advertising, and other goods or services
in connection with this agreement.

         10.4 COLLECTED REVENUES DEFINITION. "Collected Revenues" means actual
payments received by or on behalf of Sprint PCS or Manager for Sprint PCS
Products and Services from others, including the customers, whose NPA-NXX is the
same as that for the portion of the Service Area served by the Service Area
Network. In determining Collected Revenues the following principles will apply.

                  (a) The following items will be treated as follows:

                           (i) Collected Revenues do not include revenues from
         federal and state subsidy funds; they are handled separately as noted
         in Section 10.1.2;

                           (ii) Collected Revenues do include any amounts
         received for the payment of Inbound Roaming charges and interconnect
         fees when calls are carried on the Service Area Network; and

                           (iii) Collected Revenues do not include any amounts
         received with respect to any changes made by Sprint PCS under Section
         9.4.

                  (b) The following items are not Collected Revenues; Sprint PCS
is obligated to remit the amounts received with respect to such items, if any,
to Manager, as follows:

                           (i) inter service area payments will be paid as
         provided under Section 10.1.3;

                           (ii) Outbound Roaming and related charges will be
         paid as provided under Section 10.1.5;

                           (iii) proceeds from the sale or lease of subscriber
         equipment and accessories will be paid to Manager, subject to the
         equipment settlement process in Section 4.1.2;

                           (iv) proceeds from sales not in the ordinary course
         of business (e.g., sales of switches, cell sites, computers, vehicles
         or other fixed assets);

                           (v) any amounts collected with respect to sales and
         use taxes, gross receipts taxes, transfer taxes, and similar taxes,
         administrative fees, telecommunications fees, and surcharges for taxes
         and fees that are collected by a carrier for the benefit of a
         governmental authority, subject to Manager's obligation under Section
         10.3; and

                           (vi) Manager will be entitled to 100% of all revenues
         received by Sprint PCS with respect to sales of Manager's Products and
         Services.

                  (c) The following items are not Collected Revenues; neither
party is obligated to remit any amounts respecting, such items:

                           (i) reasonable adjustments of a customer's account
         (e.g., if Sprint PCS or Manager reduces a customer's bill, then the
         amount of the adjustment is not Collected Revenues); and


                                       20
<PAGE>   27


                           (ii) amount of bad debt and fraud associated with
         customers whose NPA-NXX is assigned to the Service Area (e.g., if
         Sprint PCS or Manager writes off a customer's bill as a bad debt, there
         are no Collected Revenues on which a fee is due to Manager).

         10.5 LATE PAYMENTS. Any amount due under this Section 10 that is not
paid by one party to the other party in accordance with the terms of this
agreement will bear interest at the Default Rate beginning (and including) the
3rd day after the due date until (and including) the date paid.

         10.6 SETOFF RIGHT IF FAILURE TO PAY AMOUNTS DUE. If Manager fails to
pay any undisputed amount due Sprint PCS or a Related Party of Sprint PCS under
this agreement, the Services Agreement, or any other agreement with Sprint PCS
or a Related Party of Sprint PCS, then Sprint PCS may setoff against its
payments to Manager under this Section 10, the following amounts:

                  (a) any amount that Manager owes to Sprint PCS or a Related
Party of Sprint PCS, including amounts due under the Services Agreement; and

                  (b) any amount that Sprint PCS reasonably estimates will be
due to Sprint PCS for the current month under the Services Agreement (e.g., if
under the Services Agreement customer care calls are billed monthly, Sprint PCS
can deduct from the weekly payment to Manager an amount Sprint PCS reasonably
estimates will be due Sprint PCS on account of such customer care calls under
the Services Agreement).

On a monthly basis Sprint PCS will true up the estimated amounts deducted
against the actual amounts due Sprint PCS and Sprint PCS' Related Parties. If
the estimated amounts deducted by Sprint PCS exceed the actual amounts due to
Sprint PCS and Sprint PCS' Related Parties, then Sprint PCS will remit the
excess to Manager with the next weekly payment. If the estimated amounts
deducted are less than the actual amounts due to Sprint PCS and its Related
Parties, then Sprint PCS may continue to setoff the payments to Manager against
the amounts due to Sprint PCS and Sprint PCS' Related Parties. This right of
setoff is in addition to any other right that Sprint PCS may have under this
agreement.

                  11. TERM; TERMINATION; EFFECT OF TERMINATION

         11.1 INITIAL TERM. This agreement commences on the date of execution

a maximum of 50 years including the Initial Term), unless at least 2 years prior
to the commencement of any renewal period either party notifies the other party
in writing that it does not wish to renew this agreement.

                  11.2.1 NON-RENEWAL RIGHTS OF MANAGER. If this agreement will

                  11.2.1.1 Manager's Put Right. Manager may within 30 days after

         purchase of the Operating Assets will occur within 20 days after the
         later of (a) the receipt by Sprint PCS of the written notice of
         determination of the Entire Business Value provided by the appraisers
         under Section 11.7 or (b) the receipt of all materials required to be

         representations and warranties made by Manager with respect to the

         purchase will be subject to the terms and conditions set forth in
         Section 11.8.

                  11.2.1.2  Manager's Purchase Right.

                           (a) If Sprint PCS owns 20 MHz or more of PCS spectrum
                  in the Service Area under the License on the date this
                  agreement is executed, then Manager may within 30 days after
                  the date Sprint PCS gives notice of nonrenewal declare its
                  intent to purchase the Disaggregated License. Subject to
                  receipt of FCC approval of the necessary disaggregation and
                  partition, Manager may purchase from Sprint PCS the
                  Disaggregated License for an amount equal to the greater of
                  (1) the original cost of the License to Sprint PCS (pro rated
                  on a pops and spectrum basis) plus the microwave relocation
                  costs paid by Sprint PCS or (2) 10% of the Entire Business
                  Value.

                           (b) Upon closing the purchase of the spectrum this
                  agreement will be deemed terminated. The closing of the
                  purchase of the Disaggregated License will occur within the
                  later of:

                                    (1) 20 days after the receipt by Manager of
                           the written notice of determination of the Entire
                           Business Value by the appraisers under Section 11.7;
                           or

                                    (2) 10 days after the approval of the sale
                           of the Disaggregated License by the FCC.

                           (c) The exercise of the purchase right, the
                  determination of the geographic extent of the Disaggregated
                  License coverage, the representations and warranties made by
                  Sprint PCS with respect to the Disaggregated License, and the
                  process for closing the purchase will be subject to the terms
                  and conditions set forth in Section 11.8.

                           (d) After the closing of the purchase Manager will
                  allow:

                                    (1) subscribers of Sprint PCS to roam on
                           Manager's network; and

                                    (2) Sprint PCS to resell Manager's Products
                           and Services.

                  Manager will charge Sprint PCS a MFN price in either case.

                  11.2.2 NON-RENEWAL RIGHTS OF SPRINT PCS. If this agreement
will terminate because of any of the following five (5) events, then Sprint PCS
may exercise its rights under Section 11.2.2.1 or, if applicable, its rights
under Section 11.2.2.2:

                  (a) Manager gives Sprint PCS timely written notice of
nonrenewal of this agreement;


                                       22
<PAGE>   29


                  (b) both parties give timely written notices of non-renewal;

                  (c) this agreement expires with neither party giving a written
notice of non-renewal;

                  (d) either party elects to terminate this agreement under
Section 11.3.4(a); or

                  (e) Manager elects to terminate this agreement under Section
11.3.4(b).

                  11.2.2.1 Sprint PCS' Purchase Right. Sprint PCS may purchase
         from Manager all of the Operating Assets. Sprint PCS will pay to
         Manager an amount equal to 80% of the Entire Business Value. The
         closing of the purchase of the Operating Assets will occur within 20
         days after the later of (a) the receipt by Sprint PCS of the written
         notice of determination of the Entire Business Value provided by the
         appraisers under Section 11.7 or (b) the receipt of all materials
         required to be delivered to Sprint PCS under Section 11.8. Upon closing
         the purchase of the Operating Assets this agreement will be deemed
         terminated. The exercise of the purchase right, the determination of
         the Operating Assets, the representations and warranties made by
         Manager with respect to the Operating Assets and the business, and the
         process for closing the purchase will be subject to the terms and
         conditions set forth in Section 11.8.

                  11.2.2.2 Sprint PCS' Put Right.

                           (a) Sprint PCS may, subject to receipt of FCC
                  approval, put to Manager the Disaggregated License for a

                  basis) plus the microwave relocation costs paid by Sprint PCS
                  or (2) 10% of the Entire Business Value.

                           (b) Upon closing the purchase of the Disaggregated
                  License this agreement will be deemed terminated. The closing
                  of the purchase of the Disaggregated License will occur within
                  the later of:

                                    (1) 20 days after the receipt by Sprint PCS
                           of the written notice of determination of the Entire
                           Business Value by the appraisers under Section 11.7;
                           or

                                    (2) 10 days after the approval of the sale
                           of the Disaggregated License by the FCC.

                           (c) The exercise of the put, the determination of the
                  geographic extent of the Disaggregated License coverage, the
                  representations and warranties made by Sprint PCS with respect
                  to the Disaggregated License, and the process for closing the
                  purchase will be subject to the terms and conditions set forth
                  in Section 11.8.

                           (d) Manager may, within 10 days after it receives
                  notice of Sprint PCS' exercise of its put, advise Sprint PCS
                  of the amount of spectrum (not to exceed 10 MHz) it wishes to
                  purchase. After the purchase Manager will allow:


                                       23

<PAGE>   30


                                    (1) subscribers of Sprint PCS to roam on
                           Manager's network; and

                                    (2) Sprint PCS to resell Manager's Products
                           and Services.

         Manager will charge Sprint PCS a MFN price in either case.

                  11.2.3 EXTENDED TERM AWAITING FCC APPROVAL. If Manager is
buying the Disaggregated License as permitted or required under Sections
11.2.1.2 or 11.2.2.2, then the Term of this agreement will extend beyond the
original expiration date until the closing of the purchase of the Disaggregated
License. The parties agree to exercise their respective commercially reasonable
efforts to obtain FCC approval of the transfer of the Disaggregated License.

         11.3 EVENTS OF TERMINATION. An "Event of Termination" is deemed to
occur when a party gives written notice to the other party of the Event of
Termination as permitted below:

                  11.3.1 TERMINATION OF LICENSE.

                  (a) At the election of either party this agreement may be
terminated at the time the FCC revokes or fails to renew the License. Unless
Manager has the right to terminate this agreement under Section 11.3.1(b),
neither party has any claim against the other party if the FCC revokes or fails
to renew the License, even if circumstances would otherwise permit one party to
terminate this agreement based on a different Event of Termination, except that
the parties will have the right to pursue claims against each other as permitted
under Section 11.4(b).

                  (b) If the FCC revokes or fails to renew the License because
of a breach of this agreement by Sprint PCS, then Manager has the right to
terminate this agreement under Section 11.3.3 and not this Section 11.3.1.

                  11.3.2 BREACH OF AGREEMENT: PAYMENT OF MONEY TERMS. At the
election of the non- breaching party this agreement may be terminated upon the
failure by the breaching party to pay any amount due under this agreement or any
other agreement between the parties or their respective Related Parties, if the
breach is not cured within 30 days after the breaching party's receipt of
written notice of the nonpayment from the non-breaching party.

                  11.3.3 BREACH OF AGREEMENT: OTHER TERMS. At the election of
the nonbreaching party this agreement may be terminated upon the material breach
by the breaching party of any material term contained in this agreement that
does not regard the payment of money, if the breach is not cured within 30 days
after the breaching party's receipt of written notice of the breach from the
non-breaching party, except the cure period will continue for a reasonable
period beyond the 30-day period, but will under no circumstances exceed 180 days
after the breaching party's receipt of written notice of the breach, if it is
unreasonable to cure the breach within the 30-day period, and the breaching
party takes action prior to the end of the 30-day period that is reasonably
likely to cure the breach and continues to diligently take action necessary to
cure the breach.

                  11.3.4 REGULATORY CONSIDERATIONS.

                  (a) At the election of either party this agreement may be
terminated if this agreement violates any applicable law in any material respect
where such violation (i) is classified as a felony or (ii)

                                       24

subjects either party to substantial monetary fines or other substantial
damages, except that before causing any termination the parties must use best
efforts to modify this agreement, as necessary to cause this agreement (as
modified) to comply with applicable law and to preserve to the extent possible
the economic arrangements set forth in this agreement.

                  (b) At the election of Manager this agreement may be
terminated if the regulatory action described under 11.3.4(a) is the result of a
deemed change of control of the License and the parties are unable to agree upon
a satisfactory resolution of the matter with the regulatory authority without a
complete termination of this agreement.

                  11.3.5 TERMINATION OF TRADEMARK LICENSE AGREEMENTS. If either
Trademark License Agreement terminates under its terms, then:

                  (a) Manager may terminate this agreement if the Trademark
License Agreement terminated because of a breach of the Trademark License
Agreement by Sprint PCS or Sprint; and

                  (b) Sprint PCS may terminate this agreement if the Trademark
License Agreement terminated because of a breach of the Trademark License
Agreement by Manager.

                  11.3.6 FINANCING CONSIDERATIONS. At the election of Sprint PCS
this agreement may be terminated upon the failure of Manager to obtain the
financing described in Exhibit 1.7 by the deadline(s) set forth on such Exhibit.

                  11.3.7 BANKRUPTCY OF A PARTY. At the election of the
non-bankrupt party, this agreement may be terminated upon the occurrence of a
Voluntary Bankruptcy or an Involuntary Bankruptcy of the other party.

                  arrangement, adjustment, protection, relief, or composition
                  for itself or its debts under any law relating to bankruptcy,
                  insolvency or reorganization or relief of debtors, or seeking,

                  its property; or

                  the actions set forth above.

                           "Involuntary Bankruptcy" means, without the consent

         11.4 EFFECT OF AN EVENT OF TERMINATION.

                  (a) Upon the occurrence of an Event of Termination, the party
with the right to terminate this agreement or to elect the remedy upon the Event
of Termination, as the case may be, may:

                           (i) in the case of an Event of Termination under
         Sections 11.3.1(a) or 11.3.7, give the other party written notice that
         the agreement is terminated effective as of the date of the notice, in
         which case neither party will have any other remedy or claim for
         damages (except any claim the non-bankrupt party has against the
         bankrupt party and any claims permitted under Section 11.4(b)); or

                           (ii) in the case of an Event of Termination other
         than under Section 11.3.1(a), give the other party written notice that

         or Section 11.6.

                  (b) If the party terminates this agreement under Section
11.4(a)(i) then all rights and obligations of each party under this agreement
will immediately cease, except that:

                           (i) any rights arising out of a breach of any terms
         of this agreement will survive any termination of this agreement;

                           (ii) the provisions described in Section 17.23 will
         survive any termination of this agreement;

                           (iii) the payment obligations under Section 10 will
         survive any termination of this agreement if, and to the extent, any
         costs or fees have accrued or are otherwise due and owing as of the
         date of termination of this agreement from Manager to Sprint PCS or any
         Sprint PCS Related Party or from Sprint PCS to Manager or any Manager
         Related Party;

                           (iv) either party may terminate this agreement in
         accordance with the terms of this agreement without any liability for
         any loss or damage arising out of or related to such termination,
         including any loss or damage arising out of the exercise by Sprint PCS
         of its rights under Section 11.6.3;


                                       26

<PAGE>   33


                           (v) Manager will use all commercially reasonable
         efforts to cease immediately all of their respective efforts to market,
         sell, promote or distribute the Sprint PCS Products and Services;

                           (vi) Sprint PCS has the option to buy from Manager
         any new unsold subscriber equipment and accessories, at the prices
         charged to Manager;

                           (vii) the parties will immediately stop making any
         statements or taking any action that might cause third parties to infer
         that any business relationship continues to exist between the parties,
         and where necessary or advisable, the parties will inform third parties
         that the parties no longer have a business relationship; and

                           (viii) if subscriber equipment and accessories are in
         transit when this agreement is terminated, Sprint PCS may, but does not
         have the obligation to, cause the freight carrier to not deliver the
         subscriber equipment and accessories to Manager but rather to deliver
         the subscriber equipment and accessories to Sprint PCS.

                  (c) If the party exercises its rights under Section
11.4(a)(ii), this agreement will continue in full force and effect until
otherwise terminated.

                  (d) If this agreement terminates for any reason other than
Manager's purchase of the Disaggregated License, Manager will not, for 3 years
after the date of termination compile, create, or use for the purpose of selling
merchandise or services similar to any Sprint PCS Products and Services, or
sell, transfer or otherwise convey to a third party, a list of customers who
purchased, leased or used any Sprint PCS Products and Services. Manager may use
such a list for its own internal analysis of its business practices and
operations. If this agreement terminates because of Manager's purchase of the
Disaggregated License, then Sprint PCS will transfer to Manager the Sprint PCS
customers with a MIN assigned to the Service Area covered by the Disaggregated
License, but Sprint PCS retains the customers of a national account and any
resellers who have entered into a resale agreement with Sprint PCS. Manager
agrees not to solicit, directly or indirectly, any customers of Sprint PCS not
transferred to Manager under this Section 11.4(d) for 2 years after the
termination of this agreement, except that Manager's advertising through mass
media will not be considered a solicitation of Sprint PCS customers.

         11.5 MANAGER'S EVENT OF TERMINATION RIGHTS AND REMEDIES. In addition to
any other right or remedy that Manager may have under this agreement, the
parties agree that Manager will have the rights and remedies set forth in this
Section 11.5 and that such rights and remedies will survive the termination of
this agreement. If Manager has a right to terminate this agreement as the result
of the occurrence of an Event of Termination under Sections 11.3.2, 11.3.3,
11.3.5 or 11.3.7 (if Manager is the non-bankrupt party), then Manager has the
right to elect one of the following three (3) remedies, except Manager cannot
elect its remedies under Sections 11.5.1 or 11.5.2 during the first 2 years of
the Initial Term with respect to an Event of Termination under Section 11.3.3.

                  11.5.1 MANAGER'S PUT RIGHT. Manager may put to Sprint PCS
within 30 days after the Event of Termination all of the Operating Assets.
Sprint PCS will pay to Manager an amount equal to 80% of the Entire Business

days after the later of:

or

                  (b) the receipt of all materials required to be delivered to
Sprint PCS under Section 11.8.

         Upon closing the purchase of the Operating Assets this agreement will
be deemed terminated. The exercise of the put, the determination of the
Operating Assets, the representations and warranties made by the Manager with
respect to the Operating Assets and the business, and the process for closing
the purchase will be subject to the terms and conditions set forth in Section
11.8.

                  11.5.2 MANAGER'S PURCHASE RIGHT.

                  (a) If Sprint PCS owns 20 MHz or more of PCS spectrum in the
Service Area under the License on the date this agreement is executed, then
Manager may, subject to receipt of FCC approval, purchase from Sprint PCS the
Disaggregated License for the greater of (1) the original cost of the License to
Sprint PCS (pro rated on a pops and spectrum basis) plus the microwave
relocation costs paid by Sprint PCS or (2) 9% (10% minus a 10% penalty) of the
Entire Business Value.

                  (b) Upon closing the purchase of the Disaggregated License
this agreement will be deemed terminated. The closing of the purchase of the
Disaggregated License will occur within the later of:

                           the written notice of determination of the Entire
                           Business Value by the appraisers under Section 11.7;
                           or

                                    (2) 10 days after the approval of the sale
                           of the Disaggregated License by the FCC.

The exercise of the purchase right, the determination of the geographic extent
of the Disaggregated License coverage, the representations and warranties made
by Sprint PCS with respect to the Disaggregated License, and the process for
closing the purchase will be subject to the terms and conditions set forth in
Section 11.8.

                  (c) After the closing of the purchase Manager will allow:

                                    (1) subscribers of Sprint PCS to roam on
                           Manager's network; and

                                    (2) Sprint PCS to resell Manager's Product
                           and Services.

Manager will charge Sprint PCS a MFN price in either case.

                  11.5.3 MANAGER'S ACTION FOR DAMAGES OR OTHER RELIEF. Manager,
in accordance with the dispute resolution process in Section 14, may seek
damages or other appropriate relief.

         11.6 SPRINT PCS' EVENT OF TERMINATION RIGHTS AND REMEDIES. In addition
to any other right or remedy that Sprint PCS may have under this agreement, the
parties agree that Sprint PCS will have the rights and remedies set forth in
this Section 11.6 and that such rights and remedies will survive the termination
of this agreement. If Sprint PCS has a right to terminate this agreement as the
result of the occurrence of an Event of Termination under Sections 11.3.2,
11.3.3, 11.3.5, 11.3.6 or 11.3.7 (if Sprint PCS is the non-bankrupt party),

                                       28
<PAGE>   35
then Sprint PCS has the right to elect one of the following four (4) remedies,
except that (i) if Sprint PCS elects the remedies under Sections 11.6.1, 11.6.2
or 11.6.4, Sprint PCS may pursue its rights under Section 11.6.3 concurrently
with its pursuit of one of the other three remedies, (ii) Sprint PCS cannot
elect its remedies under Sections 11.6.1 or 11.6.2 during the first 2 years
of the Initial Term with respect to an Event of Termination under Section 11.3.3
(unless the Event of Termination is caused by a breach related to the Build-out
Plan or the build-out of the Service Area Network), and (iii) Sprint PCS cannot
elect its remedy under Section 11.6.2 during the first 2 years of the Initial
Term with respect to an Event of Termination under Section 11.3.6.

                  11.6.1 SPRINT PCS' PURCHASE RIGHT. Sprint PCS may purchase
from Manager all of the Operating Assets. Sprint PCS will pay to Manager an
amount equal to 72% (80% minus a 10% penalty) of the Entire Business Value. The

the later of:

                  (a) the receipt by Sprint PCS of the written notice of
determination of the Entire Business Value by the appraisers pursuant to Section
11.7; or

                  (b) the receipt of all materials required to be delivered to
Sprint PCS under Section 11.8.

         Upon closing the purchase of the Operating Assets this agreement will
be deemed terminated. The exercise of the purchase right, the determination of
the Operating Assets, the representations and warranties made by Manager with
respect to the Operating Assets and the business, and the process for closing
the purchase will be subject to the terms and conditions set forth in Section
11.8.

                                    (1) 20 days after the receipt by Sprint PCS
                           of the written notice of determination of the Entire
                           Business Value by the appraisers under Section 11.7;
                           or

                                    (2) 10 days after the approval of the sale

                  (c) The exercise of the put, the determination of the
geographic extent of the Disaggregated License coverage, the representations and

Sprint PCS' exercise of its put, advise Sprint PCS of the amount of spectrum
(not to exceed 10 MHz) it wishes to purchase. After the closing of the purchase
Manager will allow:

                                       29

<PAGE>   36



                                    (1) subscribers of Sprint PCS to roam on
                           Manager's network; and

                                    (2) Sprint PCS to resell Manager's Products
                           and Services.

Manager will charge Sprint PCS a MFN price in either case.

                  11.6.3 SPRINT PCS' RIGHT TO CAUSE A CURE.

                  (a) Sprint PCS' Right. Sprint PCS may, but is not obligated
to, take such action as it deems necessary to cure Manager's breach of this
agreement, including assuming operational responsibility for the Service Area
Network to complete construction, continue operation, complete any necessary
repairs, implement changes necessary to comply with the Program Requirements and
terms of this agreement, or take such other steps as are appropriate under the
circumstances, or Sprint PCS may designate a third party or parties to do the
same, to assure uninterrupted availability and deliverability of Sprint PCS
Products and Services in the Service Area, or to complete the build-out of the
Service Area Network in accordance with the terms of this agreement. In the
event that Sprint PCS elects to exercise its right under this Section 11.6.3,
Sprint PCS will give Manager written notice of such election. Upon giving such
notice:

                                    (1) Manager will collect and make available
                           at a convenient, central location at its principal
                           place of business, all documents, books, manuals,
                           reports and records related to the Build-out Plan and
                           required to operate and maintain the Service Area
                           Network; and

                                    (2) Sprint PCS, its employees, contractors
                           and designated third parties will have the
                           unrestricted right to enter the facilities and
                           offices of Manager for the purpose of curing the
                           breach and, if Sprint PCS deems necessary, operate
                           the Service Area Network.

Manager agrees to cooperate with and assist Sprint PCS to the extent requested
by Sprint PCS to enable Sprint PCS to exercise its rights under this Section
11.6.3.

                  (b) Liability. Sprint PCS' exercise of its rights under this
Section 11.6.3 will not be deemed an assumption by Sprint PCS of any liability
attributable to Manager or any other party, except that, without limiting the
provisions of Section 13, during the period that Sprint PCS is curing a breach
under this agreement or operating any portion of the Service Area Network
pursuant to this Section 11.6.3, Sprint PCS will indemnify and defend Manager
and its directors, partners, officers, employees and agents from and against,
and reimburse and pay for, all claims, demands, damages, losses, judgments,
awards, liabilities, costs and expenses (including reasonable attorneys' fees,
court costs and other expenses of litigation), whether or not arising out of
third party claims, in connection with any suit, claim, action or other legal
proceeding relating to the bodily injury, sickness or death of persons or the
damage to or destruction of property, real or personal, resulting from or
arising out of Sprint PCS' negligence or willful misconduct in curing the breach
or in the operation of the Service Area Network. Sprint PCS' obligation under
this Section 11.6.3(b) will not apply to the extent of any claims, demands,
damages, losses, judgments, awards, liabilities, costs and expenses resulting
from the negligence or willful misconduct of Manager or arising from any
contractual obligation of Manager.

                  (c) Costs and Payments. During the period that Sprint PCS is
curing a breach or operating the Service Area Network under this Section 11.6.3,
Sprint PCS and Manager will continue to make any and all payments due to the
other party and to third parties under this agreement, the Services Agreement
and any other agreements to which such party is bound, except that Sprint PCS
may deduct from its payments to Manager all reasonable costs and expenses
incurred by Sprint PCS in connection with the exercise of its right under this
Section 11.6.3. Sprint PCS' operation of the Service Area Network pursuant to
this Section 11.6.3 is not a substitution for Manager's performance of its
obligations under this agreement and does not relieve Manager of its other
obligations under this agreement.

                  (d) Length of Right. Sprint PCS may continue to operate the
Service Area Network in accordance with Section 11.6.3 until (i) Sprint PCS
cures all breaches by Manager under this agreement; (ii) Manager cures all
breaches and demonstrates to Sprint PCS' satisfaction that it is financially and
operationally willing, ready and able to perform in accordance with this
agreement and resumes such performance; (iii) Sprint PCS consummates the
purchase of the Operating Assets under Section 11.6.1 or the sale of the
Disaggregated License under Section 11.6.2; or (iv) Sprint PCS terminates this
agreement.

                  (e) Not Under Services Agreement. The exercise by Sprint PCS
of its right under this Section 11.6.3 does not represent services rendered
under the Services Agreement, and therefore it does not allow Manager to be
deemed in compliance with the Program Requirements under Sections 7.1(a)(ii),
8.1(b).

                  11.6.4 SPRINT PCS' ACTION FOR DAMAGES OR OTHER RELIEF. Sprint
PCS, in accordance with the dispute resolution process in Section 14, may seek
damages or other appropriate relief.

         11.7 DETERMINATION OF ENTIRE BUSINESS VALUE.

                  11.7.1 APPOINTMENT OF APPRAISERS. Sprint PCS and Manager must
each designate an independent appraiser within 30 days after giving the Purchase
Notice under Exhibit 11.8. Sprint PCS and Manager will direct the two appraisers
to jointly select a third appraiser within 15 days after the day the last of
them is appointed. Each appraiser must be an expert in the valuation of wireless
telecommunications businesses. Sprint PCS and Manager must direct the three
appraisers to each determine, within 45 days after the appointment of the last
appraiser, the Entire Business Value. Sprint PCS and Manager will each bear the
costs of the appraiser appointed by it, and they will share equally the costs of
the third appraiser.

                  11.7.2 MANAGER'S OPERATING ASSETS. The following assets are
included in the Operating Assets (as defined in the Schedule of Definitions):

                  (a) network assets, including all personal property, real
property interests in cell sites and switch sites, leasehold interests,
collocation agreements, easements, and rights-of-way;

                  (b) all of the real, personal, tangible and intangible
property and contract rights that Manager owns and uses in conducting , the
business of providing the Sprint PCS Products and Services, including the
goodwill resulting from Manager's customer base;

                  (c) sale and distribution assets primarily dedicated (i.e., at
least 80% of their revenue is derived from the sale of Sprint PCS Products and
Services) to the sale by Manager of Sprint PCS Products and Services. For
example, a retail store that derives at least 80% of its revenue from the sale
of Sprint PCS


                                       31
<PAGE>   38


Products and Services is an Operating Asset. A store that derives 65 % of its
revenue from Sprint PCS Products and Services is not an Operating Asset;

                  (d) customers, if any, that use both the other products and
services approved under Section 3.2 and the Sprint PCS Products and Services;

                  (e) handset inventory;

                  (f) books and records of the wireless business, including all
engineering drawings and designs and financial records; and

                  (g) all contracts used by Manager in operating the wireless
business including T1 service agreements, service contracts, interconnection
agreements, distribution agreements, software license agreements, equipment
maintenance agreements, sales agency agreements and contracts with all equipment
suppliers.

                  11.7.3 ENTIRE BUSINESS VALUE. Utilizing the valuation
principles set forth below and in Section 11.7.4, "Entire Business Value" means
the fair market value of Manager's wireless business in the Service Area, valued
on a going concern basis.

                  (a) The fair market value is based on the price a willing
buyer would pay a willing seller for the entire on-going business.

                  (b) The appraisers will use the then-current customary means
of valuing a wireless telecommunications business.

                  (c) The business is conducted under the Brands and existing
agreements between the parties and their respective Related Parties.

                  (d) Manager owns the Disaggregated License (in the case where
Manager will be buying the Disaggregated License under Sections 11.2.1.2,
11.2.2.2, 11.5.2 or 11.6.2) or Manager owns the spectrum and the frequencies
actually used by Manager under this agreement (in the case where Sprint PCS will
be buying the Operating Assets under Sections 11.2.1.1, 11.2.2.1, 11.5.1 or
11.6.1).

                  (e) The valuation will not include any value for the business
represented by Manager's Products and Services or any business not directly
related to Sprint PCS Products and Services.

                  11.7.4 CALCULATION OF ENTIRE BUSINESS VALUE. The Entire
Business Value to be used to determine the purchase price of the Operating
Assets or the Disaggregated License under this agreement is as follows:

                  (a) If the highest fair market value determined by the
appraisers is within 10% of the lowest fair market value, then the Entire
Business Value used to determine the purchase price under this agreement will be
the arithmetic mean of the three appraised fair market values.

                  (b) If two of the fair market values determined by the
appraisers are within 10% of one another, and the third value is not within 10%
of the other fair market values, then the Entire Business Value


                                       32
<PAGE>   39


used to determine the purchase price under this agreement will be the arithmetic
mean of the two more closely aligned fair market values.

                  (c) If none of the fair market values is within 10% of the
other two fair market values, then the Entire Business Value used to determine
the purchase price under this agreement will be the middle value of the three
fair market values.

         11.8 CLOSING TERMS AND CONDITIONS. The closing terms and conditions for
the transactions contemplated in this Section 11 are attached as Exhibit 11.8.

         11.9 CONTEMPORANEOUS AND IDENTICAL APPLICATION. The parties agree that
any action regarding renewal or non-renewal and any Event of Termination will
occur contemporaneously and identically with respect to all Licenses. For
example, if Manager exercises its purchase right under Section 11.5.2, it must
exercise such right with respect to all of the Licenses under this agreement.
The Term of this agreement will be the same for all Licenses; Manager will not
be permitted to operate a portion of the Service Area Network with fewer than
all of the Licenses.

         12.  BOOKS AND RECORDS; CONFIDENTIAL INFORMATION; INSURANCE

         12.1 BOOKS AND RECORDS.

                  12.1.1 GENERAL. Each party must keep and maintain books and
records to support and document any fees, costs, expenses or other charges due
in connection with the provisions set forth in this agreement. The records must
be retained for a period of at least 3 years after the fees, costs, expenses or
other charges to which the records relate have accrued and have been paid, or
such other period as may be required by law.

                  12.1.2 AUDIT. On reasonable advance notice, each party must
provide access to appropriate records to the independent auditors selected by
the other party for purposes of auditing the amount of fees, costs, expenses or
other charges payable in connection with the Service Area with respect to the
period audited. The auditing party will conduct the audit no more frequently
than annually. If the audit shows that Sprint PCS was underpaid then, unless the
amount is contested, Manager will pay to Sprint PCS the amount of the
underpayment within 10 Business Days after Sprint PCS gives Manager written
notice of the determination of the underpayment. If the audit determines that
Sprint PCS was overpaid then, unless the amount is contested, Sprint PCS will
pay to Manager the amount of the overpayment within 10 Business Days after
Sprint PCS determines Sprint PCS was overpaid. The auditing party will pay all
costs and expenses related to the audit unless the amount owed to the audited
party is reduced by more than 10% or the amount owed by the audited party is
increased by more than 10%, in which case the costs and expenses related to the
audit will be paid by the audited party.

         Notwithstanding the above provisions of this Section 12.1.2, rather
than allow Manager's independent auditors access to Sprint PCS' records, Sprint
PCS may provide a report issued in conformity with Statement of Auditing
Standard No. 70 "Reports on the Processing of Transactions by Service
Organizations" ("Type II Report" or "Manager Management Report"). Such report
will be prepared by independent auditors and will provide an opinion on the
controls placed in operation and tests of operating effectiveness of those
controls in effect at Sprint PCS over the Manager Management Processes. "Manager
Management Processes" include


                                       33
<PAGE>   40




those services generally provided within the Management Agreement, primarily
billing and collection of Collected Revenues.

                  12.1.3 CONTESTING AN AUDIT. If the party that did not select
the independent auditor does not agree with the findings of the audit, then such
party can contest the findings by providing notice of such disagreement to the
other party (the "Dispute Notice"). The date of delivery of such notice is the
"Dispute Notice Date." If the parties are unable to resolve the disagreement
within 10 Business Days after the Dispute Notice Date, they will resolve the
disagreement in accordance with the following procedures.

         The two parties and the auditor that conducted the audit will all agree
on an independent certified public accountant with a regional or national
accounting practice in the wireless telecommunications industry (the "Arbiter")
within 15 Business Days after the Dispute Notice Date. If, within 15 Business
Days after the Dispute Notice Date, the three parties fail to agree on the
Arbiter, then at the request of either party to this agreement, the Arbiter will
be selected pursuant to the rules then in effect of the American Arbitration
Association. Each party will submit to the Arbiter within 5 Business Days after
its selection and engagement all information reasonably requested by the Arbiter
to enable the Arbiter to independently resolve the issue that is the subject of
the Dispute Notice. The Arbiter will make its own determination of the amount of
fees, costs, expenses or other charges payable under this agreement with respect
to the period audited. The Arbiter will issue a written report of its
determination in reasonable detail and will deliver a copy of the report to the
parties within 10 Business Days after the Arbiter receives all of the
information reasonably requested. The determination made by the Arbiter will be
final and binding and may be enforced by any court having jurisdiction. The
parties will cooperate fully in assisting the Arbiter and will take such actions
as are necessary to expedite the completion of and to cause the Arbiter to
expedite its assignment.

         If the amount owed by a contesting party is reduced by more than 10% or
the amount owed to a contesting party is increased by more than 10% then the
non-contesting party will pay the costs and expenses of the Arbiter, otherwise
the contesting party will pay the costs and expenses of the Arbiter.

         12.2 CONFIDENTIAL INFORMATION.

                  (a) Except as specifically authorized by this agreement, each
of the parties must, for the Term and 3 years after the date of termination of
this agreement, keep confidential, not disclose to others and use only for the
purposes authorized in this agreement, all Confidential Information disclosed by
the other party to the party in connection with this agreement, except that the
foregoing obligation will not apply to the extent that any Confidential
Information:

                           (i) is or becomes, after disclosure to a party,
         publicly known by any means other than through unauthorized acts or
         omissions of the party or its agents; or

                           (ii) is disclosed in good faith to a party by a third
         party entitled to make the disclosure.

                  (b) Notwithstanding the foregoing, a party may use, disclose
or authorize the disclosure of Confidential Information that it receives that:

                           (i) has been published or is in the public domain, or
         that subsequently comes into the public domain, through no fault of the
         receiving party;


                                       34
<PAGE>   41


                           (ii) prior to the effective date of this agreement
         was properly within the legitimate possession of the receiving party,
         or subsequent to the effective date of this agreement, is lawfully
         received from a third party having rights to publicly disseminate the
         Confidential Information without any restriction and without notice to
         the recipient of any restriction against its further disclosure;

                           (iii) is independently developed by the receiving
         party through persons or entities who have not had, either directly or
         indirectly, access to or knowledge of the Confidential Information;

                           (iv) is disclosed to a third party consistent with
         the terms of the written approval of the party originally disclosing
         the information;

                           (v) is required by the receiving party to be produced
         under order of a court of competent jurisdiction or other similar
         requirements of a governmental agency, and the Confidential Information
         will otherwise continue to be Confidential Information required to be
         held confidential for purposes of this agreement;

                           (vi) is required by the receiving party to be
         disclosed by applicable law or a stock exchange or association on which
         the receiving party's securities (or those of its Related Parties) are
         or may become listed; or

                           (vii) is disclosed by the receiving party to a
         financial institution or accredited investor (as that term is defined
         in Rule 501(a) under the Securities Act of 1933) that is considering
         providing financing to the receiving party and which financial
         institution or accredited investor has agreed to keep the Confidential
         Information confidential in accordance with an agreement at least as
         restrictive as this Section 12.2.

                  (c) Notwithstanding the foregoing, Manager and Sprint PCS
authorize each other to disclose to the public in regulatory filings the other's
identity and the Service Area to be developed and managed by Manager, and
Manager authorizes Sprint PCS to mention Manager and the Service Area in public
relations announcements.

                  (d) The party making a disclosure under Sections 12.2(b)(v),
12.2(b)(vi) or 12.2(b)(vii) must inform the disclosing party as promptly as is
reasonably necessary to enable the disclosing party to take action to, and use
the party's reasonable best efforts to, limit the disclosure and maintain
confidentiality to the extent practicable.

                  (e) Manager will not except when serving in the capacity of
Manager under this agreement, use any Confidential Information of any kind that
it receives under or in connection with this agreement. For example, if Manager
operates a wireless company in a different license area, Manager may not use any
of the Confidential Information received under or in connection with this
agreement in operating the other wireless business.

         12.3 INSURANCE.

                  12.3.1 GENERAL. During the term of this agreement, Manager
must obtain and maintain, and will cause any subcontractors to obtain and
maintain, with financially reputable insurers licensed to do business


                                       35
<PAGE>   42


in all jurisdictions where any work is performed under this agreement and who
are reasonably acceptable to Sprint PCS, the insurance described in the Sprint
PCS Insurance Requirements. The Sprint PCS Insurance Requirements as of the date
of this agreement are attached as Exhibit 12.3. Sprint PCS may modify the Sprint
PCS Insurance Requirements as is commercially reasonable from time to time by
delivering to Manager a new Exhibit 12.3.

                  12.3.2 WAIVER OF SUBROGATION. Manager must look first to any
insurance in its favor before making any claim against Sprint PCS or Sprint, and
their respective directors, officers, employees, agents or representatives for
recovery resulting from injury to any person (including Manager's or its
subcontractor's employees) or damage to any property arising from any cause,
regardless of negligence. Manager does hereby release and waive to the fullest
extent permitted by law, and will cause its respective insurers to waive, all
rights of recovery by subrogation against Sprint PCS or Sprint, and their
respective directors, officers, employees, agents or representatives.

                  12.3.3 CERTIFICATES OF INSURANCE. Manager and all of its
subcontractors, if any, must, as a material condition of this agreement and
prior to the commencement of any work under and any renewal of this agreement,
deliver to Sprint PCS a certificate of insurance, satisfactory in form and
content to Sprint PCS, evidencing that the above insurance, including waiver of
subrogation, is in force and will not be canceled or materially altered without
first giving Sprint PCS at least 30 days prior written notice and that all
coverages are primary to any insurance carried by Sprint PCS, its directors,
officers, employees, agents or representatives.

         Nothing contained in this Section 12.3.3 will limit Manager's liability
to Sprint PCS, its directors, officers, employees, agents or representatives to
the limits of insurance certified or carried.

                               13. INDEMNIFICATION

         13.1 INDEMNIFICATION BY SPRINT PCS. Sprint PCS agrees to indemnify,
defend and hold harmless Manager, its directors, managers, officers, employees,
agents and representatives from and against any and all claims, demands, causes
of action, losses, actions, damages, liability and expense, including costs and
reasonable attorneys' fees, against Manager, its directors, managers, officers,
employees, agents and representatives arising from or relating to the violation
by Sprint PCS of any law, regulation or ordinance applicable to Sprint PCS or by
Sprint PCS' breach of any representation, warranty or covenant contained in this
agreement or any other agreement between Sprint PCS or Sprint PCS' Related
Parties and Manager or Manager's Related Parties except where and to the extent
the claim, demand, cause of action, loss, action, damage, liability and/or
expense results solely from the negligence or willful misconduct of Manager.

         13.2 INDEMNIFICATION BY MANAGER. Manager agrees to indemnify, defend
and hold harmless Sprint PCS and Sprint, and their respective directors,
managers, officers, employees, agents and representatives from and against any
and all claims, demands, causes of action, losses, actions, damages, liability
and expense, including costs and reasonable attorneys' fees, against Sprint PCS
or Sprint, and their respective directors, managers, officers, employees, agents
and representatives arising from or relating to Manager's violation of any law,
regulation or ordinance applicable to Manager, Manager's breach of any
representation, warranty or covenant contained in this agreement or any other
agreement between Manager or Manager's Related Parties and Sprint PCS and Sprint
PCS' Related Parties, Manager's ownership of the Operating Assets or the
operation of the Service Area Network, or the actions or failure to act of any
of Manager's contractors, subcontractors, agents, directors, managers, officers,
employees and representatives of any of them in the


                                       36
<PAGE>   43


performance of any work under this agreement, except where and to the extent the
claim, demand, cause of action, loss, action, damage, liability and expense
results solely from the negligence or willful misconduct of Sprint PCS or
Sprint, as the case may be.

         13.3 PROCEDURE.

                  13.3.1 NOTICE. Any party being indemnified ("Indemnitee") will
give the party making the indemnification ("Indemnitor") written notice as soon
as practicable but no later than 5 Business Days after the party becomes aware
of the facts, conditions or events that give rise to the claim for
indemnification if:

                  (a) any claim or demand is made or liability is asserted
against Indemnitee; or

                  (b) any suit, action, or administrative or legal proceeding is
instituted or commenced in which Indemnitee is involved or is named as a
defendant either individually or with others.

         Failure to give notice as described in this Section 13.3.1 does not
modify the indemnification obligations of this provision, except if Indemnitee
is harmed by failure to provide timely notice to Indemnitor, then Indemnitor
does not have to indemnify Indemnitee for the harm caused by the failure to give
the timely notice.

                  13.3.2 DEFENSE BY INDEMNITOR. If within 30 days after giving
notice Indemnitee receives written notice from Indemnitor stating that
Indemnitor disputes or intends to defend against the claim, demand, liability,
suit, action or proceeding, then Indemnitor will have the right to select
counsel of its choice and to dispute or defend against the claim, demand,
liability, suit, action or proceeding, at its expense.

         Indemnitee will fully cooperate with Indemnitor in the dispute or
defense so long as Indemnitor is conducting the dispute or defense diligently
and in good faith. Indemnitor is not permitted to settle the dispute or claim
without the prior written approval of Indemnitee, which approval will not be
unreasonably withheld. Even though Indemnitor selects counsel of its choice,
Indemnitee has the right to retain additional representation by counsel of its
choice to participate in the defense at Indemnitee's sole cost and expense.

                  13.3.3 DEFENSE BY INDEMNITEE. If no notice of intent to
dispute or defend is received by Indemnitee within the 30-day period, or if a
diligent and good faith defense is not being or ceases to be conducted,
Indemnitee has the right to dispute and defend against the claim, demand or
other liability at the sole cost and expense of Indemnitor and to settle the
claim, demand or other liability, and in either event to be indemnified as
provided in this Section 13.3.3. Indemnitee is not permitted to settle the
dispute or claim without the prior written approval of Indemnitor, which
approval will not be unreasonably withheld.

                  13.3.4 COSTS. Indemnitor's indemnity obligation includes
reasonable attorneys' fees, investigation costs, and all other reasonable costs
and expenses incurred by Indemnitee from the first notice that any claim or
demand has been made or may be made, and is not limited in any way by any
limitation on the amount or type of damages, compensation, or benefits payable
under applicable workers' compensation acts, disability benefit acts, or other
employee benefit acts.

                             14. DISPUTE RESOLUTION

         14.1 NEGOTIATION. The parties will attempt in good faith to resolve any
dispute arising out of or relating to this agreement promptly by negotiation
between or among representatives who have authority to settle the controversy.
Either party may escalate any dispute not resolved in the normal course of
business to the appropriate (as determined by the party) officers of the parties
by providing written notice to the other party.

         Within 10 Business Days after delivery of the notice, the appropriate
officers of each party will meet at a mutually acceptable time and place, and
thereafter as often as they deem reasonably necessary, to exchange relevant
information and to attempt to resolve the dispute.

         Either party may elect, by giving written notice to the other party, to
escalate any dispute arising out of or relating to the determination of fees
that is not resolved in the normal course of business or by the audit process
set forth in Sections 12.1.2 and 12.1.3, first to the appropriate financial or
accounting officers to be designated by each party. The designated officers will
meet in the manner described in the preceding paragraph. If the matter has not
been resolved by the designated officers within 30 days after the notifying
party's notice, either party may elect to escalate the dispute to the
appropriate (as determined by the party) officers in accordance with the prior
paragraphs of this Section 14.1.

         14.2 UNABLE TO RESOLVE. If a dispute has not been resolved within 60
days after the notifying party's notice, either party may continue to operate
under this agreement and sue the other party for damages or seek other
appropriate remedies as provided in this agreement. If, and only if, this
agreement does not provide a remedy (as in the case of Sections 3.4 and 4.5,
where the parties are supposed to reach an agreement), then either party may
give the other party written notice that it wishes to resolve the dispute or
claim arising out of the parties' inability to agree under such Sections of this
agreement by using the arbitration procedure set forth in this Section 14.2.
Such arbitration will occur in Kansas City, Missouri, unless the parties
otherwise mutually agree, with the precise location being as agreed upon by the
parties or, absent such agreement, at a location in Kansas City, Missouri
selected by Sprint PCS. Such arbitration will be conducted pursuant to the
procedures prescribed by the Missouri Uniform Arbitration Act, as amended from
time to time, or, if none, pursuant to the rules then in effect of the American
Arbitration Association (or at any other place and by any other form of
arbitration mutually acceptable to the parties). Any award rendered in such
arbitration will be confidential and will be final and conclusive upon the
parties, and a judgment on the award may be entered in any court of the forum,
state or federal, having jurisdiction. The expenses of the arbitration will be
borne equally by the parties to the arbitration, except that each party must pay
for and bear the cost of its own experts, evidence, and attorneys' fees.

         The parties must each, within 30 days after either party gives notice
to the other party of the notifying party's desire to resolve a dispute or claim
under the arbitration procedure in this Section 14.2, designate an independent
arbitrator, who is knowledgeable with regard to the wireless telecommunications
industry, to participate in the arbitration hearing. The two arbitrators thus
selected will select a third independent arbitrator, who is knowledgeable with
regard to the wireless telecommunications industry, who will act as chairperson
of the board of arbitration. If, within 15 days after the day the last of the
two named arbitrators is appointed, the two named arbitrators fail to agree upon
the third, then at the request of either party, the third arbitrator shall be
selected pursuant to the rules then in effect of the American Arbitration
Association. The three independent arbitrators will comprise the board of
arbitration, which will preside over the arbitration hearing and will render all
decisions by majority vote. If either party refuses or neglects to appoint an
independent arbitrator within such 30-day period, the independent arbitrator who
has been appointed as of the 31st day after the notifying party's notice will be
the sole independent arbitrator and will solely preside over the arbitration
hearing. The


                                       38
<PAGE>   45


arbitration hearing will commence no sooner than 30 days after the date the last
arbitrator is appointed and no later than 60 days after such date. The
arbitration hearing will be conducted during normal working hours on Business
Days without interruption or adjournment of more than 2 Business Days at any one
time or 6 Business Days in the aggregate.

         The arbitrators will deliver their decision to the parties in writing
within 10 days after the conclusion of the arbitration hearing. The arbitration
award will be accompanied by findings of fact and a statement of reasons for the
decision. There will be no appeal from the written decision, except as permitted
by applicable law. The arbitration proceedings, the arbitrators' decision, the
arbitration award, and any other aspect, matter, or issue of or relating to the
arbitration are confidential, and disclosure of such confidential information is
an actionable breach of this agreement.

         Notwithstanding any other provision of this agreement, arbitration will
not be required of any issue for which injunctive relief is properly sought by
either party.

         14.3 ATTORNEYS AND INTENT. If an officer intends to be accompanied at a
meeting by an attorney, the other party's officer will be given at least 3
Business Days prior notice of the intention and may also be accompanied by an
attorney. All negotiations under Section 14.1 are confidential and will be
treated as compromise and settlement negotiations for purposes of the Federal
Rules of Civil Procedure and state rules of evidence and civil procedure.

         14.4 TOLLING OF CURE PERIODS. Any cure period under Section 11.3 that
is less than 90 days will be tolled during the pendency of the dispute
resolution process. Any cure period under Section 11.3 that is 90 days or longer
will not be tolled during the pendency of the dispute resolution process.

                       15. REPRESENTATIONS AND WARRANTIES

         Each party for itself makes the following representations and
warranties to the other party:

         15.1 DUE INCORPORATION OR FORMATION; AUTHORIZATION OF AGREEMENTS. The
party is either a corporation, limited liability company, or limited partnership
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization. Manager is qualified to do business and in
good standing in every jurisdiction in which the Service Area is located. The
party has the full power and authority to execute and deliver this agreement and
to perform its obligations under this agreement.

         15.2 VALID AND BINDING OBLIGATION. This agreement constitutes the valid
and binding obligation of the party, enforceable in accordance with its terms,
except as may be limited by principles of equity or by bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally.

         15.3 NO CONFLICT; NO DEFAULT. Neither the execution, delivery and
performance of this agreement nor the consummation by the party of the
transactions contemplated in this agreement will conflict with, violate or
result in a breach of (a) any law, regulation, order, writ, injunction, decree,
determination or award of any governmental authority or any arbitrator,
applicable to such party, (b) any term, condition or provision of the articles
of incorporation, certificate of limited partnership, certificate of
organization, bylaws, partnership agreement or limited liability company
agreement (or other governing documents) of such party or of any


                                       39
<PAGE>   46


material agreement or instrument to which such party is or may be bound or to
which any of its material properties or assets is subject.

         15.4 LITIGATION. No action, suit, proceeding or investigation is
pending or, to the knowledge of the party, threatened against or affecting the
party or any of its properties, assets or businesses in any court or before or
by any governmental agency that could, if adversely determined, reasonably be
expected to have a material adverse effect on the party's ability to perform its
obligations under this agreement. The party has not received any currently
effective notice of any default that could reasonably be expected to result in a
breach of the preceding sentence.

                            16. REGULATORY COMPLIANCE

         16.1 REGULATORY COMPLIANCE. Manager will construct, operate, and manage
the Service Area Network in compliance with applicable federal, state, and local
laws and regulations, including Siting Regulations. Nothing in this Section 16.1
will limit Manager's obligations under Section 2.2 and the remainder of this
Section 16. Manager acknowledges that failure to comply with applicable federal,
state, and local laws and regulations in its construction, operation, and
management of the Service Area Network may subject the parties and the License
to legal and administrative agency actions, including forfeiture penalties and
actions that affect the License, such as license suspension and revocation, and
accordingly, Manager agrees that it will cooperate with Sprint PCS to maintain
the License in full force and effect.

         Manager will write and implement practices and procedures governing
construction and management of the Service Area Network in compliance with
Siting Regulations. Manager will make its Siting Regulations practices and
procedures available upon request to Sprint PCS in the manner specified by
Sprint PCS for its inspection and review, and Manager will modify those Siting
Regulations practices and procedures as may be requested by Sprint PCS. Every
six months, and at the request of Sprint PCS, Manager will provide a written
certification from one of Manager's chief officers that Manager's Service Area
Network complies with Siting Regulations. Manager's first certification of
compliance with Siting Regulations will be provided to Sprint PCS six months
after the date of this agreement.

         Manager will conduct an audit and physical inspection of its Service
Area Network at the request of Sprint PCS to confirm compliance with Siting
Regulations, and Manager will report the results of the audit and physical
inspection to Sprint PCS in the form requested by Sprint PCS. Manager will bear
the cost of Siting Regulations compliance audits and physical inspections
requested by Sprint PCS.

         Manager will retain for 3 years records demonstrating compliance with
Siting Regulations, including compliance audit and inspection records. Manager
will make those records available upon request to Sprint PCS for production,
inspection, and copying in the manner specified by Sprint PCS. Sprint PCS will
bear the cost of production, inspection, and copying.

         16.2 FCC COMPLIANCE. The parties agree to comply with all applicable
FCC rules governing the License or the Service Area Network and specifically
agree as follows:

                  (a) The party billing a customer will advise the customer that
service is provided over spectrum licensed to Sprint PCS. Neither Manager nor
Sprint PCS will represent itself as the legal representative of the other before
the FCC or any other third party, but will cooperate with each other with
respect to FCC matters concerning the License or the Service Area Network.


                                       40
<PAGE>   47


                  (b) Sprint PCS will use commercially reasonable efforts to
maintain the License in accordance with the terms of the License and all
applicable laws, policies and regulations and to comply in all material respects
with all other legal requirements applicable to the operation of the Sprint PCS
Network and its business. Sprint PCS has sole responsibility, except as
specifically provided otherwise in Section 2.2, for keeping the License in full
force and effect and for preparing submissions to the FCC or any other relevant
federal, state or local authority of all reports, applications, interconnection
agreements, renewals, or other filings or documents. Manager must cooperate and
coordinate with Sprint PCS' actions to comply with regulatory requirements,
which cooperation and coordination must include, without limitation, the
provision to Sprint PCS of all information that Sprint PCS deems necessary to
comply with the regulatory requirements. Manager must refrain from taking any
action that could impede Sprint PCS from fulfilling its obligations under the
preceding sentence, and must not take any action that could cause Sprint PCS to
forfeit or cancel the License.

                  (c) Sprint PCS and Manager are familiar with Sprint PCS'
responsibility under the Communications Act of 1934, as amended, and applicable
FCC rules. Nothing in this agreement is intended to diminish or restrict Sprint
PCS' obligations as an FCC Licensee and both parties desire that this agreement
and each party's obligations under this agreement be in compliance with the FCC
rules.

                  (d) Nothing in this agreement will preclude Sprint PCS from
permitting or facilitating resale of Sprint PCS Products and Services to the
extent required or elected under applicable FCC regulations. Manager will take
the actions necessary to facilitate Sprint PCS' compliance with FCC regulations.
To the extent permitted by applicable regulations, Sprint PCS will not authorize
a reseller that desires to sell services and products in only the Service Area
to resell Sprint PCS wholesale products and services, unless Manager agrees in
advance to such sales.

                  (e) If a change in FCC policy or rules makes it necessary to
obtain FCC consent for the implementation, continuation or further effectuation
of any term or provision of this agreement, Sprint PCS will use all commercially
reasonable efforts diligently to prepare, file and prosecute before the FCC all
petitions, waivers, applications, amendments, rulemaking comments and other
related documents necessary to secure and/or retain FCC approval of all aspects
of this agreement. Manager will use commercially reasonable efforts to provide
to Sprint PCS any information that Sprint PCS may request from Manager with
respect to any matter involving Sprint PCS, the FCC, the License, the Sprint PCS
Products and Services or any other products and services approved under Section
3.2. Each party will bear its own costs of preparation of the documents and
prosecution of the actions.

                  (f) If the FCC determines that this agreement is inconsistent
with the terms and conditions of the License or is otherwise contrary to FCC
policies, rules and regulations, or if regulatory or legislative action
subsequent to the date of this agreement alters the permissibility of this
agreement under the FCC's rules or other applicable law, rules or regulations,
then the parties must use best efforts to modify this agreement as necessary to
cause this agreement (as modified) to comply with the FCC policies, rules,
regulations and applicable law and to preserve to the extent possible the
economic arrangements set forth in this agreement.

                  (g) Manager warrants and represents to Sprint PCS that Manager
is and at all times during the Term of this agreement will be in compliance with
FCC rules and regulations regarding limits on classes and amounts of spectrum
that may be owned by Manager. Manager agrees that in the event that Manager is
or at any time becomes in violation of such rules and regulations, Manager will
promptly take all


                                       41
<PAGE>   48



action necessary and appropriate (other than terminating this agreement) to cure
such violation and comply with such rules and regulations, including without
limitation disposing of its direct or indirect interests in cellular licenses.

         16.3 MARKING AND LIGHTING. Manager will conform to applicable FAA
standards when Siting Regulations require marking and lighting of Manager's
Service Area Network cell sites. Manager will cooperate with Sprint PCS in
reporting lighting malfunctions as required by Siting Regulations.

         16.4 REGULATORY NOTICES. Manager will, within 2 Business Days after its
receipt, give Sprint PCS written notice of all oral and written communications
it receives from regulatory authorities (including but not limited to the FCC,
the FAA, state public service commissions, environmental authorities, and
historic preservation authorities) and complaints respecting Manager's
construction, operation, and management of the Service Area Network that could
result in actions affecting the License as well as written notice of the details
respecting such communications and complaints, including a copy of any written
material received in connection with such communications and complaints. Manager
will cooperate with Sprint PCS in responding to such communications and
complaints received by Manager. Sprint PCS has the right to respond to all such
communications and complaints, with counsel and consultants of its own choice.
If Sprint PCS chooses to respond to such communications and complaints, Manager
will not respond to them without the consent of Sprint PCS, and Manager will pay
the costs of Sprint PCS' responding to such communications and complaints,
including reasonable attorneys' and consultants' fees, investigation costs, and
all other reasonable costs and expenses incurred by Sprint PCS.

         16.5 REGULATORY POLICY-SETTING PROCEEDINGS. Manager will not intervene
in or otherwise participate in a rulemaking, investigation, inquiry, contested
case, or similar regulatory policy setting proceedings before a regulatory
authority concerning the License or construction, operation, and management of
the Service Area Network and the Sprint PCS business operated using the Service
Area Network.

                             17. GENERAL PROVISIONS

         17.1 NOTICES. Any notice, payment, demand, or communication required or
permitted to be given by any provision of this agreement must be in writing and
mailed (certified or registered mail, postage prepaid, return receipt
requested), sent by hand or overnight courier, or sent by facsimile (with
acknowledgment received and a copy sent by overnight courier), charges prepaid
and addressed as described on the Notice Address Schedule attached to the Master
Signature Page, or to any other address or number as the person or entity may
from time to time specify by written notice to the other parties.

         All notices and other communications given to a party in accordance
with the provisions of this agreement will be deemed to have been given when
received.

         17.2 CONSTRUCTION. This agreement will be construed simply according to
its fair meaning and not strictly for or against either party.

         17.3 HEADINGS. The table of contents, section and other headings
contained in this agreement are for reference purposes only and are not intended
to describe, interpret, define, limit or expand the scope, extent or intent of
this agreement.


                                       42
<PAGE>   49


         17.4 FURTHER ACTION. Each party agrees to perform all further acts and
execute, acknowledge, and deliver any documents that may be reasonably
necessary, appropriate, or desirable to carry out the intent and purposes of
this agreement.

         17.5 COUNTERPART EXECUTION. This agreement will be executed by affixing
the parties' signatures to the Master Signature Page, which Master Signature
Page, and thus this agreement, may be executed in any number of counterparts
with the same effect as if both parties had signed the same document. All
counterparts will be construed together and will constitute one agreement.

         17.6 SPECIFIC PERFORMANCE. Each party agrees with the other party that
the party would be irreparably damaged if any of the provisions of this
agreement were not performed in accordance with their specific terms and that
monetary damages alone would not provide an adequate remedy. Accordingly, in
addition to any other remedy to which the non-breaching party may be entitled,
at law or in equity, the non- breaching party will be entitled to injunctive
relief to prevent breaches of this agreement and specifically to enforce the
terms and provisions of this agreement.

         17.7 ENTIRE AGREEMENT; AMENDMENTS. The provisions of this agreement,
the Services Agreement and the Trademark License Agreements (including the
exhibits to those agreements) set forth the entire agreement and understanding
between the parties as to the subject matter of this agreement and supersede all
prior agreements, oral or written, and other communications between the parties
relating to the subject matter of this agreement. Except for Sprint PCS' right
to amend the Program Requirements in accordance with Section 9.2 and its right
to unilaterally modify and amend certain other provisions as expressly provided
in this agreement, this agreement may be modified or amended only by a written
amendment signed by persons or entities authorized to bind each party and, with
respect to the sections set forth for Sprint on the Master Signature Page, the
persons or entities authorized to bind Sprint.

         17.8 LIMITATION ON RIGHTS OF OTHERS. Except as set forth on the Master
Signature Page for Sprint, nothing in this agreement, whether express or
implied, will be construed to give any person or entity other than the parties
any legal or equitable right, remedy or claim under or in respect of this
agreement.

         17.9 WAIVERS.

                  17.9.1 WAIVERS-GENERAL. The observance of any term of this
agreement may be waived (whether generally or in a particular instance and
either retroactively or prospectively) by the party entitled to enforce the
term, but any waiver is effective only if in a writing signed by the party
against which the waiver is to be asserted. Except as otherwise provided in this
agreement, no failure or delay of either party in exercising any power or right
under this agreement will operate as a waiver of the power or right, nor will
any single or partial exercise of any right or power preclude any other or
further exercise of the right or power or the exercise of any other right or
power.

                  17.9.2 WAIVERS-MANAGER. Manager is not in breach of any
covenant in this agreement and no Event of Termination will have occurred as a
result of the occurrence of any event, if Manager had delegated to Sprint
Spectrum under the Services Agreement (or any successor to that agreement)
responsibility for taking any action necessary to ensure compliance with the
covenant or to prevent the occurrence of the event.


                                       43
<PAGE>   50


                  17.9.3 FORCE MAJEURE. Neither Manager nor Sprint PCS, as the
case may be, is in breach of any covenant in this agreement and no Event of
Termination will occur as a result of the failure of such party to comply with
such covenant, if such party's noncompliance with the covenant results primarily
from:

                           (i) any FCC order or any other injunction issued by
         any governmental authority impeding the party's ability to comply with
         the covenant;

                           (ii) the failure of any governmental authority to
         grant any consent, approval, waiver, or authorization or any delay on
         the part of any governmental authority in granting any consent,
         approval, waiver or authorization;

                           (iii) the failure of any vendor to deliver in a
         timely manner any equipment or services; or

                           (iv) any act of God, act of war or insurrection,
         riot, fire, accident, explosion, labor unrest, strike, civil unrest,
         work stoppage, condemnation or any similar cause or event not
         reasonably within the control of such party.

         17.10 WAIVER OF JURY TRIAL. EACH PARTY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT
OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

         17.11 BINDING EFFECT. Except as otherwise provided in this agreement,
this agreement is binding upon and inures to the benefit of the parties and
their respective and permitted successors, transferees, and assigns, including
any permitted successor, transferee or assignee of the Service Area Network or
of the License. The parties intend that this agreement bind only the party
signing this agreement and that the agreement is not binding on the Related
Parties of a party unless the agreement expressly provides that Related Parties
are bound.

         17.12 GOVERNING LAW. The internal laws of the State of Missouri
(without regard to principles of conflicts of law) govern the validity of this
agreement, the construction of its terms, and the interpretation of the rights
and duties of the parties.

         17.13 SEVERABILITY. The parties intend every provision of this
agreement to be severable. If any provision of this agreement is held to be
illegal, invalid, or unenforceable for any reason, the parties intend that a
court enforce the provision to the maximum extent permissible so as to effect
the intent of the parties (including the enforcement of the remaining
provisions). If necessary to effect the intent of the parties, the parties will
negotiate in good faith to amend this agreement to replace the unenforceable
provision with an enforceable provision that reflects the original intent of the
parties.

         17.14 LIMITATION OF LIABILITY. NO PARTY 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, THIS AGREEMENT, EXCEPT WHERE SUCH
DAMAGES OR LOSS OF PROFITS ARE CLAIMED BY OR AWARDED TO A THIRD PARTY IN A


                                       44
<PAGE>   51


CLAIM OR ACTION AGAINST WHICH A PARTY TO THIS AGREEMENT HAS A SPECIFIC
OBLIGATION TO INDEMNIFY ANOTHER PARTY TO THIS AGREEMENT.

         17.15 NO ASSIGNMENT; EXCEPTIONS.

                  17.15.1 GENERAL. Neither party will, directly or indirectly,
assign this agreement or any of the party's rights or obligations under this
agreement without the prior written consent of the other party, except as
otherwise specifically provided in this Section 17.15. Sprint PCS may deny its
consent to any assignment or transfer in its sole discretion except as otherwise
provided in this Section 17.15.

         Any attempted assignment of this agreement in violation of this Section
17.15 will be void and of no effect.

         A party may assign this agreement to a Related Party of the party,
except that Manager cannot assign this agreement to a Related Party that is a
significant competitor of Sprint, Sprint PCS or their respective Related Parties
in the telecommunications business. Except as provided in Section 17.15.5, an
assignment does not release the assignor from its obligations under this
agreement unless the other party to this agreement consents in writing in
advance to the assignment and expressly grants a release to the assignor.

         Except as provided in Section 17.15.5, Sprint PCS must not assign this
agreement to any entity that does not also own the License covering the Service
Area directly or indirectly through a Related Party. Manager must not assign
this agreement to any entity (including a Related Party), unless such entity
assumes all rights and obligations under the Services Agreement, the Trademark
License Agreements and any related agreements.

                  17.15.2 ASSIGNMENT RIGHT OF MANAGER TO FINANCIAL LENDER. If
Manager is no longer able to satisfy its financial obligations and other duties,
then Manager has the right to assign its obligations and rights under this
agreement to its Financial Lender, if:

                  (a) Manager or Financial Lender provides Sprint PCS at least
10 days advance written notice of such assignment;

                  (b) Financial Lender cures or commits to cure any outstanding
material breach of this agreement by Manager prior to the end of any applicable
cure period. If Financial Lender fails to make a timely cure then Sprint PCS may
exercise its rights under Section 11;

                  (c) Financial Lender agrees to serve as an interim trustee for
the obligations and duties of Manager under this agreement for a period not to
exceed 180 days. During this interim period, Financial Lender must identify a
proposed successor to assume the obligations and rights of Manager under this
agreement;

                  (d) Financial Lender assumes all of Manager's rights and
obligations under the Services Agreement, the Trademark License Agreements and
any related agreements; and

                  (e) Financial Lender provides to Sprint PCS advance written
notice of the proposed successor to Manager that Financial Lender has identified
("Successor Notice"). Sprint PCS may give to Financial Lender written notice of
Sprint PCS' decision whether to consent to such proposed successor within


                                       45
<PAGE>   52


30 days after Sprint PCS' receipt of the Successor Notice. Sprint PCS may not
unreasonably withhold such consent, except that Sprint PCS is not required to
consent to a proposed successor that:

                           (i) has, in the past, materially breached prior
         agreements with Sprint PCS or its Related Parties;

                           (ii) is a significant competitor of Sprint PCS or its
         Related Parties in the telecommunications business;

                           (iii) does not meet Sprint PCS' reasonable credit
         criteria;

                           (iv) fails to execute an assignment of all relevant
         documents related to this agreement including the Services Agreement
         and the Trademark License Agreements; or

                           (v) refuses to assume the obligations of Manager
         under this Agreement, the Services Agreement, the Trademark License
         Agreements and any related agreements.

         If Sprint PCS fails to provide a response to Financial Lender within 30
days after receiving the Successor Notice, then the proposed successor is deemed
rejected. Any Financial Lender disclosed on the Build-out Plan on Exhibit 2.1
is deemed acceptable to Sprint PCS.

                  17.15.3 CHANGE OF CONTROL RIGHTS. If there is a Change of
Control of Manager, then:

                  (a) Manager must provide to Sprint PCS advance written notice
detailing relevant and appropriate information about the new ownership interests
effecting the Change of Control of Manager.

                  (b) Sprint PCS must provide to Manager written notice of its
decision whether to consent to or reject the proposed Change of Control within
30 days after its receipt of such notice. Sprint PCS may not unreasonably
withhold such consent, except that Sprint PCS is not required to consent to a
Change of Control in which:

                           (i) the final controlling entity or any of its
         Related Parties has in the past materially breached prior agreements
         with Sprint PCS or its Related Parties;

                           (ii) the final controlling entity or any of its
         Related Parties is a significant competitor of Sprint PCS or its
         Related Parties in the telecommunications business;

                           (iii) the final controlling entity does not meet
         Sprint PCS' reasonable credit criteria;

                           (iv) the final controlling entity fails to execute an
         assignment of all relevant documents related to this agreement
         including the Services Agreement and the Trademark License Agreements;
         or

                           (v) the final controlling entity or its Related
         Parties refuse to assume the obligations of Manager under this
         agreement.


                                       46
<PAGE>   53


                  (c) In the event that Sprint PCS provides notice that it does
not consent to the Change of Control, Manager is entitled to either:

                           (i) contest such determination pursuant to the
         dispute resolution procedure in Section 14; or

                           (ii) abandon the proposed Change of Control.

                  (d) Nothing in this agreement requires Sprint PCS' consent to:

                           (i) a public offering of Manager that does not result
         in a Change of Control (i.e., a shift from one party being in control
         to no party being in control is not a Change of Control); or

                           (ii) a recapitalization or restructuring of the
         ownership interests of Manager that Manager determines is necessary to:

                                    (A) facilitate the acquisition of commercial
                  financing and lending arrangements that will support Manager's
                  operations and efforts to fulfill its obligations under this
                  agreement; and

                                    (B) that does not constitute a Change of
                  Control.

                  (e) "Change of Control" means a situation where in any one
transaction or series of related transactions occurring during any 365-day
period, the ultimate parent entity of the Manager changes. The ultimate parent
entity is to be determined using the Hart-Scott-Rodino Antitrust Improvements
Act of 1976 rules. A Change of Control does not occur if:

                           (i) a party changes the form of its organization
         without materially changing their ultimate ownership (e.g., converting
         from a limited partnership to a limited liability company); or

                           (ii) one of the owners of the party on the date of
         this agreement or on the date of the closing of Manager's initial
         equity offering for purposes of financing its obligations under this
         agreement ultimately gains control over the party, unless such party is
         a significant competitor of Sprint PCS or Sprint PCS' Related Parties
         in the telecommunications business.

                  17.15.4 RIGHT OF FIRST REFUSAL. Notwithstanding any other
provision in this agreement, Manager grants Sprint PCS the right of first
refusal described below. If Manager determines it wishes to sell an Offered
Interest, upon receiving any Offer to purchase an Offered Interest, Manager
agrees to promptly deliver to Sprint PCS an Offer Notice. The Offer Notice is
deemed to constitute an offer to sell to Sprint PCS, on the terms set forth in
the Offer, all but not less than all of the Offered Interest. Sprint PCS will
have a period of 60 days from the date of the Offer Notice to notify Manager
that it agrees to purchase the Offered Interest on such terms. If Sprint PCS
timely agrees in writing to purchase the Offered Interest, the parties will
proceed to consummate such purchase not later than the 180th day after the date
of the Offer Notice. If Sprint PCS does not agree within the 60-day period to
purchase the Offered Interest, Manager will have the right, for a period of 120
days after such 60th day, subject to the restrictions set forth in this Section
17, to sell to the person or entity identified in the Offer Notice all of the
Offered Interest on terms and conditions no less favorable to Manager than those
set forth in the Offer. If Manager fails to sell the Offered


                                       47
<PAGE>   54


Interest to such person or entity on such terms and conditions within such
120-day period, Manager will again be subject to the provisions of this Section
17.15.4 with respect to the Offered Interest.

                  17.15.5 TRANSFER OF SPRINT PCS NETWORK. Sprint PCS may sell,
transfer or assign the Sprint PCS Network or any of the Licenses, including its
rights and obligations under this agreement, the Services Agreement and any
related agreements, to a third party without Manager's consent so long as the
third party assumes the rights and obligations under this agreement and the
Services Agreement. Manager agrees that Sprint PCS and Sprint PCS' Related
Parties will be released from any and all obligations under and with respect to
any and all such agreements upon such sale, transfer or assignment in accordance
with this Section 17.15.5, without the need for Manager to execute any document
to effect such release.

         17.16 PROVISION OF SERVICES BY SPRINT SPECTRUM. As described in the
Recitals, the party or parties to this agreement that own the Licenses are
referred to in this agreement as "Sprint PCS." Sprint Spectrum will provide most
or all of the services required to be provided by Sprint PCS under this
agreement on behalf of Sprint PCS, other than the services to be rendered by
Manager. For example, Sprint Spectrum is the party to the contracts relating to
the national distribution network, the roaming and long distance services, and
the procurement arrangements. Accordingly, Sprint PCS and Manager will deal with
Sprint Spectrum to provide many of the attributes of the Sprint PCS Network.

         17.17 NUMBER PORTABILITY. Manager understands that the manner in which
customers are assigned to the Service Area Network could change as telephone
numbers become portable without any relation to the service area in which they
are initially activated. To the extent the relationship between NPA-NXX and the
Service Area changes, Sprint PCS will develop an alternative system to attempt
to assign customers who primarily live and work in the Service Area to the
Service Area. The terms of this agreement will be deemed to be amended to
reflect the new system that Sprint PCS develops.

         17.18 DISCLAIMER OF AGENCY. Neither party by this agreement makes the
other party a legal representative or agent of the party, nor does either party
have the right to obligate the other party in any manner, except if the other
party expressly permits the obligation by the party or except for provisions in
this agreement expressly authorizing one party to obligate the other.

         17.19 INDEPENDENT CONTRACTORS. The parties do not intend to create any
partnership, joint venture or other profit-sharing arrangement, landlord-tenant
or lessor-lessee relationship, employer-employee relationship, or any other
relationship other than that expressly provided in this agreement. Neither party
to this agreement has any fiduciary duty to the other party.

         17.20 EXPENSE. Each party bears the expense of complying with this
agreement except as otherwise expressly provided in this agreement. The parties
must not allocate any employee cost or other cost to the other party, except as
otherwise provided in the Program Requirements or to the extent the parties
expressly agree in advance to the allocation.

         17.21 GENERAL TERMS.

                  (a) This agreement is to be interpreted in accordance with the
following rules of construction:

                           (i) The definitions in this agreement apply equally
         to both the singular and plural forms of the terms defined unless the
         context otherwise requires.

                           (iii) All references in this agreement to Sections

                           (iv) All references to any agreement or other
         instrument or statute or regulation are to it as amended and
         supplemented from time to time (and, in the case of a statute or
         regulation, to any corresponding provisions of successor statutes or
         regulations), unless the context otherwise requires.

                  (b) Any reference in this agreement to a "day" or number of
"days" (without the explicit qualification of "Business") is a reference to a
calendar day or number of calendar days. If any action or notice is to be taken
or given on or by a particular calendar day, and the calendar day is not a
Business Day, then the action or notice may be taken or given on the next
Business Day.

         17.22 CONFLICTS WITH OTHER AGREEMENTS. The provisions of this
Management Agreement govern over those of the Services Agreement if the
provisions contained in this agreement conflict with analogous provisions in the

11.5, 11.6, 12.2, 13, 14, 16 and 17 of this agreement will survive any

executed a Restructuring and Merger Agreement and related agreements that
provide for restructuring the ownership of Sprint Spectrum L.P., SprintCom,
Inc., PhillieCo Partners I, L.P., and Cox Communications PCS, L.P. Upon
consummation of the transactions contemplated by those agreements, Sprint would
control each of the four entities. While Sprint and Sprint PCS anticipate the
proposed transactions will be consummated, there can be no assurances.

         17.25 ADDITIONAL TERMS AND PROVISIONS. Certain additional and
supplemental terms and provisions of this agreement, if any, are set forth in
the Addendum to Sprint PCS Management Agreement attached hereto and incorporated
herein by this reference. Manager represents and warrants that the Addendum also
describes all existing contracts and arrangements (written or verbal) that
relate to or affect the rights of Sprint PCS or Sprint under this agreement
(e.g., agreements relating to long distance telephone services (Section 3.4) or
backhaul and transport services (Section 3.7)).

any conflicting terms and provisions contained in the Management Agreement.
Except for express modification made in this Addendum, the Management Agreement
continues in full force and effect.

         Capitalized terms used and not otherwise defined in this Addendum have
the meaning ascribed to them in the Schedule of Definitions. Section and Exhibit
references are to Sections and Exhibits of the Management Agreement unless
otherwise noted.

         The Management Agreement is modified as follows:

         1. COVERAGE ENHANCEMENT. Section 2.5 is deleted in its entirety and
replaced by the following language:

                [TEXT OMITTED - CONFIDENTIAL TREATMENT REQUESTED]

         2. REGULATORY NOTICES (COSTS). The following two sentences replace the
last sentence of Section 16.4: "If Sprint PCS chooses to respond to such
communications and complaints, Manager will not respond to them without the
consent of Sprint PCS. Sprint PCS will bear the cost of responding to any such
communications and complaints unless (1) such response is primarily the result
of Manager's acts or omissions that constitute negligence, willful misconduct,
or breach of any provision of this agreement (in which case Manager will pay the
costs of Sprint PCS' response), or (2) Manager's response is not requested by
Sprint PCS."

         3. COMPLIANCE. Sprint PCS acknowledges that smaller population centers
within the Service Area may merit an adjusted application of Sprint PCS' Retail
Store requirements and its Customer Service requirements in order to preserve
the economic benefits of this agreement for Manager and Sprint PCS. Accordingly,
with respect to cities located within the Service Area having a population of
less than 100,000 according to the most recently completed United States
government census), Sprint PCS will exercise commercial reasonableness with
respect to its Retail Store requirements and its Customer Service requirements.

         4. VOLUNTARY RESALE OF PRODUCTS AND SERVICES. Section 3.5.2 is modified
by amending the second sentence of the second paragraph in its entirety to read
as follows: "If Manager wants handsets of subscribers of resellers with NPA-NXXs
of Manager to be activated, Manager must agree to comply with the terms of the
program, including its pricing provisions."

         5. FINANCING. (a) The word "and" is inserted between the words
"thereto" and "before" in the last sentence of Section 1.7.

         (b) The following paragraph is added at the end of Section 1.7:

         Sprint PCS agrees to propose modifications to the Management Agreement,
and perhaps to the Schedule of Definitions, the Services Agreement, the Sprint
Trademark and Service Mark License Agreement, and the Sprint Spectrum Trademark
and Service Mark License Agreement, that will enhance Manager's ability to
obtain financing for the Service Area Network. Sprint PCS will not be required
to offer the Manager subsequent modifications offered or agreed to with Other
Managers subsequent to the initial set of modifications.

         6. LONG-DISTANCE PRICING. (a) The first sentence of Section 3.4 is
deleted in its entirety and replaced by the following language:

                  Manager must purchase long-distance telephony services from
         Sprint through Sprint PCS both (i) to provide long-distance telephony
         service to users of the Sprint PCS Network and (ii) to

December 23, 1999

<PAGE>   74


         connect the Service Area Network with the national platforms used by
         Sprint PCS to provide services to Manager under the agreement and/or
         the Services Agreement. Sprint will bill Sprint PCS for such services
         rendered to Sprint PCS, Manager and all Other Managers, and in turn,
         Sprint PCS will bill Manager for the services used by Manager. Manager
         will be charged the same price for such long-distance service as Sprint
         PCS is charged by Sprint (excluding interservice area long-distance
         travel rates) plus an additional administrative fee to cover Sprint
         PCS' processing costs.

         (b) The following sentence is added as a second paragraph in Section
3.4: "Manager may not resell the long-distance telephony services acquired from
Sprint under this Section 3.4."

         7. RIGHT OF LAST OFFER. Section 3.7 is modified by adding the following
language: "(other than backhaul services relating to national platform and IT
application connections, which Manager must purchase from Sprint)" both between
(i) "Service Area Network" and "if Manager decides to use" in the first sentence
of the first paragraph and (ii) "for these services" and "and the agreement was
not made" in the first sentence of the second paragraph.

         8. NON-TERMINATION OF AGREEMENT. The following language is added at the
end of Section 11.5.3 and Section 11.6.4: "but such action does not terminate
this agreement."

         9. ANNOUNCED TRANSACTIONS. Section 17.24 is deleted in its entirety.

         10. ADDITIONAL TERMS AND PROVISIONS. The phrase "the Addendum also
describes" is deleted from the second sentence of Section 17.25, and the
following language is inserted at the end of that second sentence: "are
described on Exhibit 17.25, and photocopies of any such written agreements have
been delivered to Sprint PCS".

         11. FEDERAL CONTRACTOR COMPLIANCE. A new Section 17.28, the text of
which is attached as Exhibit A, is added and incorporated by this reference.
When and to the extent required by applicable law, Manager will comply with the
requirement of this Section 17.28.

         12. YEAR 2000 COMPLIANCE. The following Section 17.29 is added:

                  17.29 YEAR 2000 COMPLIANCE. Sprint PCS and Manager each
         separately represents and warrants that any system or equipment
         acquired, operated or designated by it for use in the Service Area
         Network or for use to support the Service Area Network, including
         (without limitation) billing, ordering and customer service system,
         will be capable of correctly processing and receiving date data, as
         well as properly exchanging date data with all products (for example,
         hardware, software and firmware) with which the Service Area Network is
         designed to be used, and will not malfunction or fail to function due
         to an inability to process correctly date data in conformance with
         Sprint PCS requirements for "Year 2000 Compliance." If the Service Area
         Network or any system used to support the Service Area Network fails to
         operate as warranted due to defects or failures in any system or
         equipment selected by Manager (including systems or equipment of third
         party vendors and subcontractors selected by Manager rather than by
         Sprint PCS) Manager will, at its own expense, make the repairs,
         replacements or upgrades necessary to correct the failure and provide a
         Year 2000 Compliant Service Area Network. If the Service Area Network
         or any system used to support the Service Area Network fails to operate
         as warranted due to defects or failures in any systems or equipment
         selected by Sprint PCS (including systems or equipment of third party
         vendors and subcontractors that Sprint PCS selects and requires Manager
         to use), Sprint PCS will, at its own


December 23, 1999

<PAGE>   75

         expense, make the repairs, replacements or upgrades necessary to
         correct the failure and provide a Year 2000 Compliant Service Area
         Network.

                  "Year 2000 Compliance" means the functions, calculations, and
         other computing processes of the Service Area Network (collectively
         "Processes") that perform and otherwise process, date-arithmetic,
         display, print or pass date/time data in a consistent manner,
         regardless of the date in time on which the Processes are actually
         performed or the dates used in such data or the nature of the date/time
         data input, whether before, during or after January 1, 2000 and whether
         or not the date/time data is affected by leap years. To the extent any
         part of the Service Area Network is intended to be used in combination
         with other software, hardware or firmware, it will properly exchange
         date/time data with such software, hardware or firmware. The Service
         Area Network will accept and respond to two-digit year-date input,
         correcting or supplementing as necessary, and store, print, display or
         pass date/time data in a manner that is unambiguous as to century. No
         date/time data will cause any part of the Service Area Network to
         perform an abnormally ending routine or function within the Processes
         or generate incorrect final values or invalid results.

         13. PAYMENT OF FEES UNDER SERVICES AGREEMENT. The second sentence of
Section 3.1 of the Services Agreement is deleted in its entirety and replaced by
the following two sentences:

                  Except with respect to fees paid for billing-related services,
         the monthly charge for any fees based on the number of subscribers of
         the Service Area Network will be determined based on the number of
         subscribers as of the 15th day of the month for which the charge is
         being calculated. With respect to fees paid for billing-related
         services, the monthly charge for any fees based on the number of
         subscribers will be based on the number of gross activations in the
         month for which the charge is being calculated plus the number of
         subscribers of the Service Area Network on the last day of the prior
         calendar mouth.

         14. SAN DIEGO ASSETS. Upon written notice to Manager by Sprint PCS of
its decision to acquire Manager's assets located within the San Diego BTA #402
(the "SD Assets"), the parties will negotiate in good faith to determine the
fair market value of the SD Assets (the "FMV").

         If the parties are unable to agree upon the FMV within 60 days after
the date on which Sprint PCS sent notice (the "Notice Date"), the parties will,
within 90 days after the Notice Date, appoint appraisers in the manner set forth
in Section 11.7.1 of the Management Agreement. The appraised value of the SD
Assets (the "Appraised Value") will be determined based on the appraisers'
valuation using the principles set forth in Section 11.7.4 of the Management
Agreement.

         Upon determination of the FMV or Appraised Value, as the case may be,
the parties will consummate the transaction on the terms and conditions set
forth in Exhibit 11.8 to the Management Agreement. Upon the consummation of the
transfer, the San Diego BTA #402 will be removed from Manager's Service Area.

                          SPRINT PCS SERVICES AGREEMENT

         This SERVICES AGREEMENT is made as of December 23,1999, by and between
SPRINT SPECTRUM L.P., a Delaware limited partnership ("SPRINT SPECTRUM"), and
ALAMOSA PCS, LLC, a Delaware limited liability company (but not any Related
Party) ("MANAGER"). THE DEFINITIONS FOR THIS AGREEMENT ARE SET FORTH ON THE
"SCHEDULE OF DEFINITIONS."

                                    RECITALS

         A.       Manager and the holder of the License ("Sprint PCS") are
entering into a Management Agreement contemporaneously with the execution of
this agreement, under which Manager will design, construct, operate, manage and
maintain a wireless services network in the Service Area in accordance with
Sprint PCS standards and will offer and promote Sprint PCS Products and Services
that operate on the Sprint PCS Network.

         B.       Manager desires to enter into this agreement with Sprint
Spectrum, under which Sprint Spectrum may furnish certain services to Manager to
assist Manager to build out, operate, manage and maintain the Service Area
Network under the License.

                                    AGREEMENT

         In consideration of the recitals and mutual covenants and agreements
contained in this agreement, the sufficiency of which are hereby acknowledged,
the parties, intending to be bound, agree as follows:

                        1. ENGAGEMENT OF SPRINT SPECTRUM

         1.1      ENGAGEMENT OF SPRINT SPECTRUM. Manager engages Sprint Spectrum
to assist Manager with certain specified services in connection with the
operations of Manager and in building out, operating, managing and maintaining
the Service Area Network, subject to the terms and conditions of this agreement.
Sprint Spectrum accepts the engagement and will use the same effort and
demonstrate the same care in performing its obligations under this agreement as
it uses in conducting its own business. Manager will use the efforts and
demonstrate the care necessary for Sprint Spectrum to meet its obligations under
this agreement. When providing the Selected Services, Sprint Spectrum will
provide those services to Manager in the same manner it provides those services
to its own business, including the use of third party vendors to provide certain
Selected Services.

         1.2      RELIANCE ON MANAGER. Manager understands that Sprint
Spectrum's ability to provide the Selected Services will depend largely on
Manager's compliance with the Sprint PCS Program Requirements under the
Management Agreement and cooperation with Sprint Spectrum. Manager agrees to
comply with such requirements and to cooperate with Sprint Spectrum to enable
Sprint Spectrum to perform its obligations under this agreement.

         1.3      NON-EXCLUSIVE SERVICE. Nothing contained in this agreement
confers upon Manager an exclusive right to any of the Available Services. Sprint
Spectrum may contract with others to provide expertise and services identical or
similar to those to be made available or provided to Manager under this
agreement.



                                        1

<PAGE>   5




         1.4      MANAGER'S USE OF SERVICES. Manager agrees it will only use the
Selected Services in connection with its Service Area Network. Manager will not
use the Selected Services outside the Service Area or in connection with any
other business.

                                   2. SERVICES

         2.1      AVAILABLE SERVICES; SELECTED SERVICES.

                  2.1.1    AVAILABLE SERVICES. Subject to the terms of this
agreement, Manager may obtain any of the Available Services from Sprint Spectrum
in accordance with the provisions of this Section 2.1. The Available Services
offered from time to time and the fees charged for such Available Services will
be set forth on the then current Exhibit 2.1.1 (the "Available Services and Fees
Schedule"). If Sprint Spectrum offers any new Available Service, it will deliver
a new Exhibit 2.1.1 indicating the new service and the fee for the new service.

                  Manager may select one or more of the categories of Available
Services. If Manager selects a particular category of services it must take and
pay for all of the services under the category selected; Manager may not select
only particular services within that category.

                  If Sprint Spectrum determines to no longer offer an Available
Service and the service is not a Selected Service, then Sprint Spectrum may give
Manager written notice at any time during the term of this agreement that Sprint
Spectrum no longer offers the Available Service.

                  Sprint Spectrum may modify Exhibit 2.1.1 from time to time.
Exhibit 2.1.1 will be deemed amended upon delivery of the new Exhibit 2.1.1 to
Manager.

                  2.1.2    SELECTED SERVICES. During the term of this agreement,
and subject to the terms of this agreement, Manager has selected, and Sprint
Spectrum has agreed to furnish or cause to be furnished to Manager, the
Available Services listed on EXHIBIT 2.1.2 (which listed services will be the
Selected Services). Sprint Spectrum may require from time to time that certain
Available Services be Selected Services where necessary to comply with legal or
regulatory requirements (e.g., mandatory provision of emergency 911 service) or
applicable operating constraints (e.g., delivery of merchandise to the regional
distribution centers of national retail distributors).

                  2.1.3    CHANGES TO SELECTED SERVICES. If Manager determines
it no longer requires a Selected Service, then Manager must give Sprint Spectrum
written notice at least 3 months prior to the date on which Manager wishes to
discontinue its use of such Selected Service.

                  If Sprint Spectrum determines to no longer offer an Available
Service and such service is one of Manager's Selected Services, then Sprint
Spectrum must give Manager written notice at least 9 months prior to its
discontinuance of such Available Service that Sprint Spectrum will no longer
offer such Available Service. If the Available Service to be discontinued is
required by Sprint Spectrum to be a Selected Service, then Sprint Spectrum will
use commercially reasonable efforts to (a) help Manager provide the service
itself or find another vendor to provide the service, and (b) facilitate
Manager's transition to the new service provider.



                                        2

<PAGE>   6




                  2.1.4    PERFORMANCE OF SELECTED SERVICES. Sprint Spectrum may
select the method, location and means of providing the Selected Services. If
Sprint Spectrum wishes to use Manager's facilities to provide the Selected
Services, Sprint Spectrum must obtain Manager's prior written consent.

         2.2      THIRD PARTY VENDORS. Some of the Available Services might be
provided by third party vendors under arrangements between Sprint Spectrum and
the third party vendors. In some instances, Manager may receive Available
Services from a third party vendor under the same terms and conditions that
Sprint Spectrum receives such services. In other instances, Manager may receive
Available Services under the terms and conditions set forth in an agreement
between Manager and the third party vendor. If Manager wishes to engage a third
party vendor to provide Available Services, Selected Services, or Available
Services that Sprint Spectrum will no longer offer, Manager must first obtain
Sprint Spectrum's prior written consent, which consent will not be unreasonably
withheld. Before Manager may obtain from the third party vendor any Available
Services, Selected Services, or Available Services that Sprint Spectrum will no
longer offer, such vendor must execute an agreement prepared by Sprint Spectrum
that obligates the vendor to maintain the confidentiality of any proprietary
information and that prohibits the vendor from using any proprietary technology,
information or methods for its benefit or the benefit of any other person or
entity. Manager's use of a third party vendor that is not providing Available
Services to Manager on behalf of Sprint PCS under the Management Agreement will
not qualify for assumed compliance with the Program Requirements under Sections
7.1 (a)(ii) or 8.1(b) of the Management Agreement.

         2.3      CONTRACTS. Manager will notify Sprint Spectrum of any contract
or other arrangement Manager has with any other party that will affect how
Sprint Spectrum is to provide the Selected Services.

                          3. FEES FOR SELECTED SERVICES

         3.1      PAYMENT OF FEES. Sprint Spectrum and Manager agree that the
fees for the Available Services will initially be those set forth on Exhibit
2.1.1, which fees represent an adjustment to any fees paid by Sprint PCS to
Manager under Section 10 of the Management Agreement. The monthly charge for any
fees based on the number of subscribers of the Service Area Network will be
determined based on the number of subscribers as of the 15th day of the month
for which the charge is being calculated. Manager agrees to pay the fees to
Sprint Spectrum within 20 days after the date of the invoice. If Manager enters
into an agreement with a third party vendor under Section 2.2, Manager agrees to
pay the fees for the services rendered by the third party vendor in accordance
with the terms and conditions of such agreement.

         3.2      ADJUSTMENT OF FEES. Sprint Spectrum may change the fee for any
service it provides once during any 12-month period by delivering a new Exhibit
2.1.1 to Manager. Exhibit 2.1.1 will be deemed amended on the effective date
noted on the new Exhibit 2.1.1, which will be at least 30 days after delivering
the new Exhibit 2.1.1. Manager must notify Sprint Spectrum in writing before the
effective date of the new Exhibit 2.1.1 if Manager wishes to discontinue a
Selected Service for which the price is being increased (a "CANCELLED SERVICE").
If Manager discontinues a Selected Service under this Section 3.2, Sprint
Spectrum will, at Manager's option, continue to provide the Cancelled Service
and to charge Manager the current fee (i.e., the fee under the Exhibit 2.1.1 in
effect on the date Manager gives its cancellation notice to Sprint Spectrum) for
the Cancelled Service for up to 9 months from the date Sprint Spectrum gives
Manager notice of the price change or until Manager no longer needs the
Cancelled Service, whichever occurs first. If Sprint Spectrum continues to
provide the Cancelled Service after the 9-month period, Sprint Spectrum will
apply the new fee, under the new Exhibit 2.1.1, and such fee will be applied
retroactively as of the effective date of the


                                        3

<PAGE>   7




new schedule. Manager agrees to pay such retroactive charge within 10 days after
the date of the invoice for such charge.

         3.3      LATE PAYMENTS. Any payment due under this Section 3 that is
not paid by Manager to Sprint Spectrum in accordance with the terms of this
agreement will bear interest at the Default Rate beginning (and including) the
6th day after the due date until (and including) the date on which such payment
is made.

         3.4      TAXES. Manager will pay or reimburse Sprint Spectrum for any
sales, use, gross receipts or similar tax, administrative fee,
telecommunications fee or surcharge for taxes or fees levied by a governmental
authority on the fees and charges payable to Sprint Spectrum by Manager.

                   4. TERM; TERMINATION; EFFECT OF TERMINATION

         4.1      TERM. This agreement commences on the date of execution and
continues until the Management Agreement terminates. This agreement
automatically terminates upon termination of the Management Agreement. Neither
party may terminate this agreement for any reason other than the termination of
the Management Agreement.

         4.2      EFFECT OF TERMINATION. Upon the termination of this agreement,
all rights and obligations of each party under this agreement will immediately
cease, except that:

                  (a)      Any rights arising out of a breach of any terms of
this agreement will survive any termination of this agreement;

                  (b)      The provisions of this Section 4.2 and Sections 5.2,
6, 7, and 9 will survive any termination of this agreement; and

                  (c)      The payment obligations under Section 3 will survive
any termination of this agreement if, and to the extent, any fees have accrued
or are otherwise due and owing from Manager to Sprint Spectrum or any Sprint
Spectrum Related Party as of the date of termination of this agreement.

                 5. BOOKS AND RECORDS; CONFIDENTIAL INFORMATION

         5.1      BOOKS AND RECORDS.

                  5.1.1    GENERAL. Each party must keep and maintain books and
records to support and document any fees, costs, expenses or other charges due
in connection with the provisions set forth in this agreement. The records must
be retained for a period of at least 3 years after the fees, costs, expenses or
other charges to which the records relate have accrued and have been paid, or
such other period as may be required by law.

                  5.1.2    AUDIT. On reasonable advance written notice by the
Manager, but no more frequently than annually, Sprint PCS will provide a report
issued in conformity with Statement of Auditing Standard No. 70 "Reports on the
Processing of Transactions by Service Organizations" ("TYPE II REPORT" or
"MANAGER MANAGEMENT REPORT"). Such report will be prepared by independent
auditors and will provide an opinion on the controls placed in operation and
tests of operating effectiveness of those controls in effect at Sprint PCS over
the Manager Management Processes. "Manager Management Processes" include those
services generally


                                        4

<PAGE>   8




provided within the Management Agreement, primarily billing and collection of
Collected Revenues. The Manager is responsible for costs incurred attributable
to such requested procedures with respect to the services provided under this
agreement, including without limitation discussion of the billing and collection
of Collected Revenues. This report will be made available to the other party
upon such other party's request.

                  5.1.3    CONTESTING AN AUDIT. If the party that did not select
the independent auditor does not agree with the findings of the audit, then such
party can contest the findings by providing notice of such disagreement to the
other party (the "DISPUTE NOTICE"). The date of delivery of such notice is the
"DISPUTE NOTICE DATE." If the parties are unable to resolve the disagreement
within 10 Business Days after the Dispute Notice Date, they will resolve the
disagreement in accordance with the following procedures.

         The two parties and the auditor that conducted the audit will all agree
on an independent certified public accountant with a regional or national
accounting practice in the wireless telecommunications industry (the "ARBITER")
within 15 Business Days after the Dispute Notice Date. If, within 15 Business
Days after the Dispute Notice Date, the three parties fail to agree on the
Arbiter, then at the request of either party to this agreement, the Arbiter will
be selected pursuant to the rules then in effect of the American Arbitration
Association. Each party will submit to the Arbiter within 5 Business Days after
its selection and engagement all information reasonably requested by the Arbiter
to enable the Arbiter to independently resolve the issue that is the subject of
the Dispute Notice. The Arbiter will make its own determination of the amount of
fees, costs, expenses or other charges payable under this agreement with respect
to the period audited. The Arbiter will issue a written report of its
determination in reasonable detail and will deliver a copy of the report to the
parties within 10 Business Days after the Arbiter receives all of the
information reasonably requested. The determination made by the Arbiter will be
final and binding and may be enforced by any court having jurisdiction. The
parties will cooperate fully in assisting the Arbiter and will take such actions
as are necessary to expedite the completion of and to cause the Arbiter to
expedite its assignment.

         If the amount owed by a contesting party is reduced by more than 10% or
the amount owed to a contesting party is increased by more than 10% then the
noncontesting party will pay the costs and expenses of the Arbiter, otherwise
the contesting party will pay the costs and expenses of the Arbiter.

         5.2      CONFIDENTIAL INFORMATION.

                  (a)      Except as specifically authorized by this agreement,
each of the parties must, for the term of this agreement and 3 years after the
date of termination of this agreement, keep confidential, not disclose to others
and use only for the purposes authorized in this agreement, all Confidential
Information disclosed by the other party to the party in connection with this
agreement, except that the foregoing obligation will not apply to the extent
that any Confidential Information:

                           (i)      is or becomes, after disclosure to a party,
         publicly known by any means other than through unauthorized acts or
         omissions of the party or its agents; or

                           (ii)     is disclosed in good faith to a party by a
         third party entitled to make the disclosure.

         (b)      Notwithstanding the foregoing, a party may use, disclose or
authorize the disclosure of Confidential Information that it receives that:



                                        5

<PAGE>   9




                           (i)      has been published or is in the public
         domain, or that subsequently comes into the public domain, through no
         fault of the receiving party;

                           (ii)     prior to the effective date of this
         agreement was properly within the legitimate possession of the
         receiving party, or subsequent to the effective date of this agreement,
         is lawfully received from a third party having rights to publicly
         disseminate the Confidential Information without any restriction and
         without notice to the recipient of any restriction against its further
         disclosure;

                           (iii)    is independently developed by the receiving
         party through persons or entities who have not had, either directly or
         indirectly, access to or knowledge of the Confidential Information;

                           (iv)     is disclosed to a third party consistent
         with the terms of the written approval of the party originally
         disclosing the information;

                           (v)      is required by the receiving party to be
         produced under order of a court of competent jurisdiction or other
         similar requirements of a governmental agency, and the Confidential
         Information will otherwise continue to be Confidential Information
         required to be held confidential for purposes of this agreement;

                           (vi)     is required by the receiving party to be
         disclosed by applicable law or a stock exchange or association on which
         the receiving party's securities (or those of its Related Parties) are
         or may become listed; or

                           (vii)    is disclosed by the receiving party to a
         financial institution or accredited investor (as that term is defined
         in Rule 501 (a) under the Securities Act of 1933) that is considering
         providing financing to the receiving party and which financial
         institution or accredited investor has agreed to keep the Confidential
         Information confidential in accordance with an agreement at least as
         restrictive as this Section 5.

         (c)      The party making a disclosure under Sections 5.2(b)(v),
5.2(b)(vi) or 5.2(b)(vii) must inform the non-disclosing party as promptly as is
reasonably necessary to enable the non-disclosing party to take action to, and
use the disclosing party's reasonable best efforts to, limit the disclosure and
maintain confidentiality to the extent practicable.

         (d)      Manager will not, except when serving in the capacity of
Manager under this agreement, use any Confidential Information of any kind that
it receives under or in connection with this agreement. For example, if Manager
operates a wireless company in a different licensed area, Manager may not use
any of the Confidential Information received under or in connection with this
agreement in operating its other wireless business.

                               6. INDEMNIFICATION

         6.1      INDEMNIFICATION BY SPRINT SPECTRUM. Sprint Spectrum agrees to
indemnify, defend and hold harmless Manager, its directors, managers, officers
and employees from and against any and all claims, demands, causes of action,
losses, actions, damages, liability and expense, including costs and reasonable
attorneys' fees, against Manager, its directors, managers, officers and
employees arising from or relating to the violation by Sprint Spectrum, its
directors, officers, employees, contractors, subcontractors, agents or


                                        6

<PAGE>   10




representatives of any law, regulation or ordinance applicable to Sprint
Spectrum in its performance of the Selected Services, or by Sprint Spectrum's,
or its directors', officers', employees', contractors', subcontractors', agents'
or representatives' breach of any representation, warranty or covenant contained
in this agreement, except where and to the extent the claim, demand, cause of
action, loss, action, damage, liability and expense results from the negligence
or willful misconduct of Manager, its directors, managers, officers, employees,
agents or representatives. Sprint Spectrum's indemnification obligations under
this Section 6.1 do not apply to any third party vendors that provide services
(including Selected Services) directly to Manager or Manager's Related Parties
under a separate agreement.

         6.2      INDEMNIFICATION BY MANAGER. Manager agrees to indemnify,
defend and hold harmless Sprint Spectrum, its directors, officers and employees
from and against any and all claims, demands, causes of action, losses, actions,
damages, liability and expense, including costs and reasonable attorneys' fees,
against Sprint Spectrum, its directors, officers and employees arising from or
relating to Manager's, or its directors', managers', officers', employees',
contractors', subcontractors', agents' or representatives' violation of any law,
regulation or ordinance applicable to Manager, or by Manager's, or its
directors', managers', officers', employees', contractors', subcontractors',
agents' or representatives' breach of any representation, warranty or covenant
contained in this agreement, Manager's ownership of the Operating Assets or the
operation of the Service Area Network, except where and to the extent the claim,
demand, cause of action, loss, action, damage, liability and expense results
from the negligence or willful misconduct of Sprint Spectrum, its directors,
officers, employees, contractors, subcontractors, agents or representatives.

         6.3      PROCEDURE.

                  6.3.1    NOTICE. Any party being indemnified ("INDEMNITEE")
will give the party making the indemnification ("INDEMNITOR") written notice as
soon as practicable but no later than 5 Business Days after the party becomes
aware of the facts, conditions or events that give rise to the claim for
indemnification if:

                           (1)      any claim or demand is made or liability is
         asserted against Indemnitee; or

                           (2)      any suit, action, or administrative or legal
         proceeding is instituted or commenced in which Indemnitee is involved
         or is named as a defendant either individually or with others.

         Failure to give notice as described in this Section 6.3.1 does not
modify the indemnification obligations of this provision, except if Indemnitor
is harmed by failure to provide timely notice to Indemnitor, then Indemnitor
does not have to indemnify Indemnitee for the harm caused by the failure to give
the timely notice.

         6.3.2    DEFENSE BY INDEMNITOR. If within 30 days after giving notice
Indemnitee receives written notice from Indemnitor stating that Indemnitor
disputes or intends to defend against the claim, demand, liability, suit, action
or proceeding, then Indemnitor will have the right to select counsel of its
choice and to dispute or defend against the claim, demand, liability, suit,
action or proceeding, at its expense.

         Indemnitee will fully cooperate with Indemnitor in the dispute or
defense so long as Indemnitor is conducting the dispute or defense diligently
and in good faith. Indemnitor is not permitted to settle the dispute or claim
without the prior written approval of Indemnitee, which approval will not be
unreasonably withheld. Even though Indemnitor selects counsel of its choice,
Indemnitee has the right to retain additional representation by counsel of its
choice to participate in the defense at Indemnitee's sole cost and expense.


                                        7

<PAGE>   11




                  6.3.3    DEFENSE BY INDEMNITEE. If no notice of intent to
dispute or defend is received by Indemnitee within the 30-day period, or if a
diligent and good faith defense is not being or ceases to be conducted,
Indemnitee has the right to dispute and defend against the claim, demand or
other liability at the sole cost and expense of Indemnitor and to settle the
claim, demand or other liability, and in either event to be indemnified as
provided in this Section 6. Indemnitee is not permitted to settle the dispute or
claim without the prior written approval of Indemnitor, which approval will not
be unreasonably withheld.

                  6.3.4 COSTS. Indemnitor's indemnity obligation includes
reasonable attorneys' fees, investigation costs, and all other reasonable costs
and expenses incurred by Indemnitee from the first notice that any claim or
demand has been made or may be made, and is not limited in any way by any
limitation on the amount or type of damages, compensation, or benefits payable
under applicable workers' compensation acts, disability benefit acts, or other
employee benefit acts.

                              7. DISPUTE RESOLUTION

         7.1      NEGOTIATION. The parties will attempt in good faith to resolve
any dispute arising out of or relating to this agreement promptly by negotiation
between or among representatives who have authority to settle the controversy.
Either party may escalate any dispute not resolved in the normal course of
business to the appropriate (as determined by the party) officers of the parties
by providing written notice to the other party.

         Within 10 Business Days after delivery of the notice, the appropriate
officers of each party will meet at a mutually acceptable time and place, and
thereafter as often as they deem reasonably necessary, to exchange relevant
information and to attempt to resolve the dispute.

         Either party may elect, by giving written notice to the other party, to
escalate any dispute arising out of or relating: to the determination of fees
that is not resolved in the normal course of business or by the audit process
set forth in Sections 5.1.2 and 5.1.3, first to the appropriate financial or
accounting officers to be designated by each party. The designated officers will
meet in the manner described in the preceding paragraph. If the matter has not
been resolved by the designated officers within 30 days after the notifying
party's notice, either party may elect to escalate the dispute to the
appropriate (as determined by the party) officers in accordance with the prior
paragraphs of this Section 7.1.

         7.2      UNABLE TO RESOLVE. If a dispute has not been resolved within
60 days after the notifying party's notice, the parties will continue to operate
under this agreement and sue the other party for damages or seek other
appropriate remedies as provided in this agreement, except neither party may
bring a suit for damages based on an event that occurs during the first two
years of this agreement.

         7.3      ATTORNEYS AND INTENT. If an officer intends to be accompanied
at a meeting by an attorney, the other party's officer will be given at least 3
Business Days prior notice of the intention and may also be accompanied by an
attorney. All negotiations under this Section 7 are confidential and will be
treated as compromise and settlement negotiations for purposes of the Federal
Rules of Civil Procedure and state rules of evidence and civil procedure.

                        8. REPRESENTATIONS AND WARRANTIES

         Each party for itself makes the following representations and
warranties to the other party:

<PAGE>   12




         8.1      DUE INCORPORATION OR FORMATION; AUTHORIZATION OF AGREEMENTS.
The party is either a corporation, limited liability company, or limited
partnership duly organized, validly existing and in good standing under the laws
of the jurisdiction of its organization. Manager is qualified to do business and
in good standing in every jurisdiction in which the Service Area is located. The
party has the full power and authority to execute and deliver this agreement and
to perform its obligations under this agreement.

         8.2      VALID AND BINDING OBLIGATION. This agreement constitutes the
valid and binding obligation of the party, enforceable in accordance with its
terms, except as may be limited by principles of equity or by bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting the
enforcement of creditors' rights generally.

         8.3      NO CONFLICT; NO DEFAULT. Neither the execution, delivery and
performance of this agreement nor the consummation by the party of the
transactions contemplated in this agreement will conflict with, violate or
result in a breach of (a) any law, regulation, order, writ, injunction, decree,
determination or award of any governmental authority or any arbitrator,
applicable to such party, or (b) any term, condition or provision of the
articles of incorporation, certificate of limited partnership, certificate of
organization, bylaws, partnership agreement or limited liability company
agreement (or other governing documents) of such party or of any material
agreement or instrument to which such party is or may be bound or to which any
of its material properties or assets is subject.

         8.4      LITIGATION. No action, suit, proceeding or investigation is
pending or, to the knowledge of the party, threatened against or affecting the
party or any of its properties, assets or businesses in any court or before or
by any governmental agency that could, if adversely determined, reasonably be
expected to have a material adverse effect on the party's ability to perform its
obligations under this agreement. The party has not received any currently
effective notice of any default that could reasonably be expected to result in a
breach of the preceding sentence.

                              9. GENERAL PROVISIONS

         9.1      NOTICES. Any notice, payment, demand, or communication
required or permitted to be given by any provision of this agreement must be in

receipt requested), sent by hand or overnight courier, or sent by facsimile
(with acknowledgment received and a copy sent by overnight courier), charges
prepaid and addressed described on the Notice Address Schedule attached to the
Master Signature Page, or to any other address or number as the person or entity
may from time to time specify by written notice to the other parties.

         All notices and other communications given to a party in accordance
with the provisions of this agreement will be deemed to have been given when
received.

         9.2      CONSTRUCTION. This agreement will be construed simply
according to its fair meaning and not strictly for or against either party.

         9.3      HEADINGS. The table of contents, section and other headings
contained in this agreement are for reference purposes only and are not intended
to describe, interpret, define, limit or expand the scope, extent or intent of
this agreement.



                                        9

<PAGE>   13




         9.4      FURTHER ACTION. Each party agrees to perform all further acts
and execute, acknowledge, and deliver any documents that may be reasonably
necessary, appropriate, or desirable to carry out the intent and purposes of
this agreement.

         9.5      SPECIFIC PERFORMANCE. Each party agrees with the other party
that the party would be irreparably damaged if any of the provisions of this
agreement were not performed in accordance with their specific terms and that
monetary damages alone would not provide an adequate remedy. Accordingly, in
addition to any other remedy to which the non-breaching party may be entitled,
at law or in equity, the non breaching party will be entitled to injunctive
relief to prevent breaches of this agreement and specifically to enforce the
terms and provisions of this agreement.

         9.6      ENTIRE AGREEMENT; AMENDMENTS. The provisions of this agreement
and the Management Agreement (if Sprint Spectrum is a party to that agreement)
(including the exhibits to those agreements) set forth the entire agreement and
understanding between the parties as to the subject matter of this agreement and
supersede all prior agreements, oral or written, and other communications
between the parties relating to the subject matter of this agreement. Except for
Sprint Spectrum's right to amend the Available Services and the fees charged for
such services as shown on Exhibit 2.1.1, and Manager's right to amend the
Selected Services listed on Exhibit 2.1.2, this agreement may be modified or
amended only by a written amendment signed by persons or entities authorized to
bind each party.

         9.7      LIMITATION ON RIGHTS OF OTHERS. Nothing in this agreement,
whether express or implied, will be construed to give any person or entity other
than the parties any legal or equitable right, remedy or claim under or in
respect of this agreement.

         9.8      WAIVERS; REMEDIES. The observance of any term of this
agreement may be waived (whether generally or in a particular instance and
either retroactively or prospectively) by the party entitled to enforce the
term, but any waiver is effective only if in a writing signed by the party
against which the waiver is to be asserted. Except as otherwise provided in this
agreement, no failure or delay of either party in exercising any power or right
under this agreement will operate as a waiver of the power or right, nor will
any single or partial exercise of any right or power preclude any other or
further exercise of the right or power or the exercise of any other right or
power.

         Sprint Spectrum is not in breach of any covenant in this agreement, if
failure of such party to comply with such covenant or Sprint Spectrum's
non-compliance with the covenant results primarily from:

                           (i)      any FCC order or any other injunction issued
         by any governmental authority impeding the ability to comply with the
         covenant;

                           (ii)     the failure of any governmental authority to
         grant any consent, approval, waiver, or authorization or any delay on
         the part of any governmental authority in granting any consent,
         approval, waiver or authorization;

                           (iii)    the failure of any vendor to deliver in a
         timely manner any equipment or service; or



                                       10

<PAGE>   14




                           (iv)     any act of God, act of war or insurrection,
         riot, fire, accident, explosion, labor unrest, strike, civil unrest,
         work stoppage, condemnation or any similar cause or event not
         reasonably within the control of Sprint Spectrum.

         9.9      WAIVER OF JURY TRIAL. EACH PARTY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT
OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

         9.10     BINDING EFFECT. Except as otherwise provided in this
agreement, this agreement is binding upon and inures to the benefit of the
parties and their respective and permitted successors, transferees, and assigns,

                  manner provided below



<PAGE>   3


                  ("Quality Standards") and those imposed by Law. Such Quality
                  Standards are designed to ensure that the quality of the
                  Sprint PCS Products and Services and Premium and Promotional
                  Items marketed, promoted, advertised, distributed, leased and
                  sold under the Licensed Marks are consistent with the high
                  reputation of the Licensed Marks and are in conformity with
                  applicable Laws.

         (b)      Establishment of Quality Standards. The parties acknowledge
                  that the initial Quality Standards for the Sprint PCS Products
                  and Services and Premium and Promotional Items are attached to
                  the Affiliation Agreement as Exhibits 4.1, 4.2, 4.3, 7.2, and
                  8.1. The Quality Standards shall (i) be consistent with the
                  reputation for quality associated with the Licensed Marks and
                  (ii) be commensurate with a high level of quality (taking into
                  account Licensee's fundamental underlying technology and
                  standards), consistent with the level of quality being offered
                  in the market for products and services of the same kind as
                  the Sprint PCS Products and Services.

         (c)      Changes in Quality Standards. In the event that Licensor
                  wishes to change the Quality Standards, it will notify
                  Licensee in writing of such proposed amendments, and will
                  afford Licensee a reasonable time period in which to adopt
                  such changes as may be required in order for Licensee to
                  conform to the amended Quality Standards.

         Section 2.2. Rights of Inspection. In order to ensure that the Quality
Standards are maintained, Licensor and its authorized agents and representatives
shall have the right, but not the obligation, with prior notice to Licensee, to
enter upon the premises of any office or facility operated by or for Licensee
with respect to Sprint PCS Products and Services and Premium and Promotional
Items at all reasonable times, to inspect, monitor and test in a reasonable
manner facilities and equipment used to furnish Sprint PCS Products and Services
and Premium and Promotional Items and, with prior written notice to Licensee, to
inspect the books and records of Licensee in a manner that does not unreasonably
interfere with the business and affairs of Licensee, all as they relate to the
compliance with the Quality Standards maintained hereunder.

         Section 2.3. Marking Compliance with Trademark Laws. Licensee shall
cause the appropriate designation "(TM)" or "(sm)" or the registration symbol
"(R)" to be placed adjacent to the Licensed Marks in connection with the use
thereof and to indicate such additional information as Licensor shall reasonably
specify from time to time concerning the license rights under which Licensee
uses the Licensed Marks. Licensee shall place the following notice on all
printed or electronic materials on which the Licensed Marks appear: "SPRINT",
the "DIAMOND" logo and "Sprint PCS", "Sprint Personal Communications Services"
are trademarks and/or service marks of Sprint Communications Company, L.P.,
"used under license" or such other notice as Licensor may specify from time to
time.

         Section 2.4. Other Use Restrictions. Licensee shall not use the
Licensed Marks in any manner that would reflect adversely on the image of
quality symbolized by the Licensed Marks.

                            CONFIDENTIAL INFORMATION

         Section 3.1. Maintenance of Confidentiality. Each of Licensor and
Licensee and their respective Controlled Related Parties (each a "Restricted
Party") shall cause their respective officers and directors (in their capacity
as such) to, and shall take all reasonable measures to cause their respective
employees, attorneys, accountants, consultants and other agents and advisors
(collectively, and together with their respective officers and directors,
"Agents") to keep secret and maintain in confidence the terms of this agreement
and all confidential and proprietary information and data of the other party or
its Related Parties disclosed to it (in each case, a "Receiving Party") in
connection with the performance of its obligations under this agreement (the
"Confidential Information") and shall not, and shall cause their respective
officers and directors not to, and shall take all reasonable measures to cause
their respective other Agents not to, disclose Confidential Information to any
Person other than the parties, their Controlled Related Parties and their
respective Agents that need to know such Confidential Information. Each party
further agrees that it shall not use the Confidential Information for any
purpose other than determining and performing its obligations and exercising its
rights under this agreement. Each party shall take all reasonable measures
necessary to prevent any unauthorized disclosure of the Confidential Information
by any of their respective Controlled Related Parties or any of their respective
Agents. The measures taken by a Restricted Party to protect Confidential
Information shall be not deemed unreasonable if the measures taken are at least
as strong as the measures taken by the disclosing party to protect such
Confidential Information.

         Section 3.2. Permitted Disclosures. Nothing herein shall prevent any
Restricted Party or its Agents from using, disclosing, or authorizing the
disclosure of Confidential Information it receives and which:

         (i)      has been published or is in the public domain, or which
                  subsequently comes into the public domain, through no fault of
                  the receiving party;

         (ii)     prior to receipt hereunder was property within the legitimate
                  possession of the Receiving Party or, subsequent to receipt
                  hereunder is lawfully received from a third party having
                  rights therein without restriction of the third party's right
                  to disseminate the Confidential Information and without notice
                  of any restriction against its further disclosure.

         (iii)    is independently developed by the Receiving Party through
                  Persons who have not had, either directly or indirectly,
                  access to or knowledge of such Confidential Information;

         (iv)     is disclosed to a third party with the written approval of the
                  party originally disclosing such information, provided that
                  such Confidential Information shall cease to be confidential
                  and proprietary information covered by this agreement only to
                  the extent of the disclosure so consented to;

         (v)      subject to the Receiving Party's compliance with Section 3.4
                  below, is required to be produced under order of a court of
                  competent jurisdiction or other similar requirements of a
                  governmental agency, provided that such Confidential
                  Information to the extent covered by a protective order or its
                  equivalent shall otherwise continue to be Confidential
                  Information required to be held confidential for purpose of
                  this agreement; or

         (vi)     subject to the Receiving Party's compliance with Section 3.4
                  below, is required to be disclosed by applicable Law or a
                  stock exchange or association on which such Receiving Party's
                  securities (or those of its Related Party) are listed.

         Section 3.3. Financial Institutions. Notwithstanding this Article 3,
any party may provide Confidential Information to any financial institution in
connection with borrowings from such financial institution by such party or any
of its Controlled Related Parties, so long as prior to any such disclosure such
financial institution executes a confidentiality agreement that provides
protection substantially equivalent to the protection provided the parties in
this Article 3.

         Section 3.4. Procedures. In the event that any Receiving Party (i) must
disclose Confidential Information in order to comply with applicable Law or the
requirements of a stock exchange or association on which such Receiving Party's
securities or those of its Related Parties are listed or (ii) becomes legally
compelled (by oral questions, interrogatories, requests for information or
documents, subpoenas, civil investigative demand or otherwise) to disclose any
Confidential Information, the Receiving Party shall provide the disclosing party
with prompt written notice so that in the case of clause (i), the disclosing
party can work with the Receiving Party to limit the disclosure to the greatest
extent possible consistent with legal obligations or in the case of clause (ii),
the disclosing party may seek a protective order or other appropriate remedy or
waive compliance with the provisions of this agreement. In the case of a clause
(ii), (A) if the disclosing party is unable to obtain a protective order or
other appropriate remedy, or if the disclosing party so directs, the Receiving
Party shall, and shall cause its employees to, exercise all commercially
reasonable efforts to obtain a protective order or other appropriate remedy at
the disclosing party's reasonable expense, and (B) failing the entry of a
protective order or other appropriate remedy or receipt of a waiver hereunder,
the Receiving Party shall furnish only that portion of the Confidential
Information which it is advised by opinion of its counsel is legally required to
be furnished and shall exercise all commercially reasonable efforts to obtain
reliable assurance that confidential treatment shall be accorded such
Confidential Information, it being understood that such reasonable efforts shall
be at the cost and expense of the disclosing party whose Confidential
Information has been sought.

         Section 3.5. Survival. The obligations under this Article 3 shall
survive, as to any party, until two (2) years following the date of termination
of this agreement, and, as to any Controlled Related Party of a party, until two
(2) years following the earlier to occur of (A) the date that such Person is no
longer a Controlled Related Party of a party, or (B) the date of the termination
of this agreement; provided that such obligations shall continue indefinitely
with respect to any trade secret or similar information which is proprietary to
a party or its Controlled Related Parties and provides such party or its
Controlled Related Parties with an advantage over its competitors.

                                    ARTICLE 4
              REPRESENTATIONS, WARRANTIES AND COVENANTS OF LICENSEE

exclusive right, title and interest in and to the Licensed Marks and
acknowledges that nothing herein shall be construed to accord to Licensee any
rights in the Service Area in the Licensed Marks except as expressly provided,

Marks shall not create in Licensee any right, title or interest in the Service
Area in the Licensed Marks and that all use in the Service Area of the Licensed

or rights in the Service Area with respect to the Licensed Marks other than the

                  pending or, to the knowledge of Licensor, threatened with
                  respect to Licensor's ownership of the Licensed Marks or
                  which, if adversely determined, would restrict or otherwise

                  Licensee of the rights purported to be granted to Licensee
                  hereunder.

         Except as expressly provided above in this Section 5.1, Licensor makes

                  have a material adverse effect on the consolidated financial

         Section 15.13. Jurisdiction; Consent to Service of Process.

         (a)      Each party hereby irrevocably and unconditionally submits, for

                  any Missouri State court sitting in the County of Jackson or

                  of or relating to this agreement, or for recognition or
                  enforcement of any judgment, and each party hereby irrevocably

                  suit, action or proceeding arising out of or relating to this

                  agreement, provided that such service shall be deemed to have
                  been given only when actually received by such party. Nothing
                  in this agreement shall affect the right of a party to serve
                  process in another manner permitted by law.

         Section 15.14. Waiver of Jury Trial. Each party waives, to the fullest

                  Licensor hereby grants to Licensee, and Licensee hereby
                  accepts from Licensor, for the term of this agreement, a

                         QUALITY STANDARDS, MAINTENANCE

         Section 2.1.  Maintenance of Quality.

         (a)      Adherence to Quality Standards. In the course of marketing,
                  promoting, advertising, distributing, leasing and selling
                  Sprint PCS Products and Services and Premium and Promotional
                  Items under the Licensed Marks, Licensee shall maintain and
                  adhere to standards of quality and specifications that conform
                  to or exceed those quality standards and technical and
                  operational specifications adopted and/or amended in the
                  manner provided below ("Quality Standards") and those imposed
                  by Law. Such Quality Standards are designed to ensure that the
                  quality of the Sprint PCS Products and Services and Premium
                  and Promotional Items marketed, promoted, advertised,
                  distributed, leased and sold under the Licensed Marks are
                  consistent with the high reputation of the Licensed Marks and
                  are in conformity with applicable Laws.

         (b)      Establishment of Quality Standards. The parties acknowledge
                  that the initial Quality Standards for the Sprint PCS Products
                  and Services and Premium and Promotional Items are attached to
                  the Management Agreement as Exhibits 4.1, 4.2, 4.3. 7.2. and
                  8.1. The Quality Standards shall (i) be consistent with the
                  reputation for quality associated with the Licensed Marks and
                  (ii) be commensurate with a high level of quality (taking into
                  account Licensee's fundamental underlying technology and
                  standards), consistent with the level of quality being offered
                  in the market for products and services of the same kind as
                  the Sprint PCS Products and Services.

         (c)      Changes in Quality Standards. In the event that Licensor
                  wishes to change the Quality Standards, it will notify
                  Licensee in writing of such proposed amendments, and will
                  afford Licensee a reasonable time period in which to adopt
                  such changes as may be required in order for Licensee to
                  conform to the amended Quality Standards.

         Section 2.2. Rights of Inspection. In order to ensure that the Quality
Standards are maintained, Licensor and its authorized agents and representatives
shall have the right, but not the obligation, with prior notice to Licensee, to
enter upon the premises of any office or facility operated by or for Licensee
with respect to Sprint PCS Products and Services and Premium and Promotional
Items at all reasonable times, to inspect, monitor and test in a reasonable
manner facilities and equipment used to furnish Sprint PCS Products and Services
and Premium and Promotional Items and, with prior written notice to Licensee, to
inspect the books and records of Licensee in a manner that does not unreasonably
interfere with the business and affairs of Licensee, all as they relate to the
compliance with the Quality Standards maintained hereunder.

         Section 2.3. Marking; Compliance with Trademark Laws. Licensee shall
cause the appropriate designation "(TM)" or "(sm)" or the registration symbol
"(R)" to be placed adjacent to the Licensed Marks in connection with the use
thereof and to indicate such additional information as Licensor shall reasonably
specify from time to time concerning the license rights under which Licensee
uses the Licensed Marks. Licensee shall place the following notice on all
printed or electronic materials on which the Licensed Marks appear: "THE CLEAR
ALTERNATIVE TO CELLULAR", "EXPERIENCE THE CLEAR ALTERNATIVE TO CELLULAR TODAY",
and such other marks as may be adopted and established from time to time, are

                                       -2-

<PAGE>   4



trademarks and/or service marks of Sprint Spectrum L.P., "used under license" or
such other notice as Licensor may specify from time to time.

         Section 2.4. Other Use Restrictions. Licensee shall not use the
Licensed Marks in any manner that would reflect adversely on the image of
quality symbolized by the Licensed Marks.

                                    ARTICLE 3
                            CONFIDENTIAL INFORMATION

         Section 3.1. Maintenance of Confidentiality. Each of Licensor and
Licensee and their respective Controlled Related Parties (each a "Restricted
Party") shall cause their respective officers and directors (in their capacity
as such) to, and shall take all reasonable measures to cause their respective
employees, attorneys, accountants, consultants and other agents and advisors
(collectively, and together with their respective officers and directors,
"Agents") to, keep secret and maintain in confidence the terms of this agreement
and all confidential and proprietary information and data of the other party or
its Related Parties disclosed to it (in each case, a "Receiving Party") in
connection with the performance of its obligations under this agreement (the
"Confidential Information") and shall not, and shall cause their respective
officers and directors not to, and shall take all reasonable measures to cause
their respective other Agents not to, disclose Confidential Information to any
Person other than the parties, their Controlled Related Parties and their
respective Agents that need to know such Confidential Information. Each party
further agrees that it shall not use the Confidential Information for any
purpose other than determining and performing its obligations and exercising its
rights under this agreement. Each party shall take all reasonable measures
necessary to prevent any unauthorized disclosure of the Confidential Information
by any of their respective Controlled Related Parties or any of their respective
Agents. The measures taken by a Restricted Party to protect Confidential
Information shall be not deemed unreasonable if the measures taken are at least
as strong as the measures taken by the disclosing party to protect such
Confidential Information.

         Section 3.2. Permitted Disclosures. Nothing herein shall prevent any
Restricted Party or its Agents from using, disclosing, or authorizing the
disclosure of Confidential Information it receives and which:

         (i)      has been published or is in the public domain, or which
                  subsequently comes into the public domain, through no fault of
                  the receiving party;

         (ii)     prior to receipt hereunder was property within the legitimate
                  possession of the Receiving Party or, subsequent to receipt
                  hereunder is lawfully received from a third party having
                  rights therein without restriction of the third party's right
                  to disseminate the Confidential Information and without notice
                  of any restriction against its further disclosure.

         (iii)    is independently developed by the Receiving Party through
                  Persons who have not had, either directly or indirectly,
                  access to or knowledge of such Confidential Information;

         (iv)     is disclosed to a third party with the written approval of the
                  party originally disclosing such information, provided that
                  such Confidential Information shall cease to be confidential
                  and proprietary information covered by this agreement only to
                  the extent of the disclosure so consented to;


                                       -3-

<PAGE>   5



         (v)      subject to the Receiving Party's compliance with Section 3.4
                  below, is required to be produced under order of a court of
                  competent jurisdiction or other similar requirements of a
                  governmental agency, provided that such Confidential
                  Information to the extent covered by a protective order or its
                  equivalent shall otherwise continue to be Confidential
                  Information required to be held confidential for purpose of
                  this agreement; or

         (vi)     subject to the Receiving Party's compliance with Section 3.4
                  below, is required to be disclosed by applicable Law or a
                  stock exchange or association on which such Receiving Party's
                  securities (or those of its Related Party) are listed.

         Section 3.3. Financial Institutions. Notwithstanding this Article, any
party may provide Confidential Information to any financial institution in
connection with borrowings from such financial institution by such party or any
of its Controlled Related Parties, so long as prior to any such disclosure such
financial institution executes a confidentiality agreement that provides
protection substantially equivalent to the protection provided the parties in
this Article 3.

         Section 3.4. Procedures. In the event that any Receiving Party (i) must
disclose Confidential Information in order to comply with applicable Law or the
requirements of a stock exchange or association on which such Receiving Party's
securities or those of its Related Parties are listed or (ii) becomes legally
compelled (by oral questions, interrogatories, requests for information or
documents, subpoenas, civil investigative demand or otherwise) to disclose any
Confidential Information, the Receiving Party shall provide the disclosing party
with prompt written notice so that in the case of clause (i), the disclosing
party can work with the Receiving Party to limit the disclosure to the greatest
extent possible consistent with legal obligations or in the case of clause (ii),
the disclosing party may seek a protective order or other appropriate remedy or
waive compliance with the provisions of this agreement. In the case of a clause
(ii), (A) if the disclosing party is unable to obtain a protective order or
other appropriate remedy, or if the disclosing party so directs, the Receiving
Party shall, and shall cause its employees to, exercise all commercially
reasonable efforts to obtain a protective order or other appropriate remedy at
the disclosing party's reasonable expense, and (B) failing the entry of a
protective order or other appropriate remedy or receipt of a waiver hereunder,
the Receiving Party shall furnish only that portion of the Confidential
Information which it is advised by opinion of its counsel is legally required to
be furnished and shall exercise all commercially reasonable efforts to obtain
reliable assurance that confidential treatment shall be accorded such
Confidential Information, it being understood that such reasonable efforts shall
be at the cost and expense of the disclosing party whose Confidential
Information has been sought.

         Section 3.5. Survival. The obligations under this Article 3 shall
survive, as to any party, until two (2) years following the date of termination
of this agreement, and, as to any Controlled Related Party of a party, until two
(2) years following the earlier to occur of (A) the date that such Person is no
longer a Controlled Related Party of a party, or (B) the date of the termination
of this agreement; provided that such obligations shall continue indefinitely
with respect to any trade secret or similar information which is proprietary to
a party or its Controlled Related Parties and provides such party or its
Controlled Related Parties with an advantage over its competitors.

                  pending or, to the knowledge of Licensor, threatened with
                  respect to Licensor's ownership of the Licensed Marks or
                  which, if adversely determined, would restrict or otherwise
                  interfere in any material respect with the exercise by
                  Licensee of the rights purported to be granted to Licensee
                  hereunder.

represents and warrants to the other party as follows:

         (a)      Due Incorporation or Formation; Authorization of Agreement.
                  Such party is a corporation duly organized, a limited
                  liability company duly organized or a partnership duly formed,
                  validly existing and, if applicable, in good standing under
                  the laws of the jurisdiction of its incorporation or formation
                  and has the corporate, company or partnership power and
                  authority to own its property and carry on its business as
                  owned and carried on at the date hereof and as contemplated
                  hereby. Such party is duly licensed or qualified to do
                  business and, if applicable, is in good standing in each of
                  the jurisdictions in which the failure to be so licensed or
                  qualified would have a material adverse effect on its
                  financial condition or its ability to perform its obligations
                  hereunder. Such party has the corporate, company or
                  partnership power and authority to execute and deliver this
                  agreement and to perform its obligations hereunder and the
                  execution, delivery and performance of this agreement have
                  been duly authorized by all necessary corporate, company or
                  partnership action. Assuming the due execution and delivery by
                  the other party hereto, this agreement constitutes the legal,
                  valid and binding obligation of such party enforceable against
                  such party in accordance with its terms, subject as to
                  enforceability to limits imposed by bankruptcy, insolvency or
                  similar laws affecting creditors' rights generally and the
                  availability of equitable remedies.

         (b)      No Conflict with Restrictions; No Default. Neither the
                  execution, delivery and performance of this agreement nor the
                  consummation by such party of the transactions contemplated
                  hereby (i) will conflict with, violate or result in a breach
                  of any of the terms, conditions or provisions of any law,

                  award of any court, any governmental department, board, agency
                  or instrumentality, domestic or foreign, or any arbitrator,
                  applicable to such party or any of its Controlled Related
                  Parties, (ii) will conflict with, violate, result in a breach
                  of or constitute a default under any of the terms, conditions
                  or provisions of the articles of incorporation, articles of
                  organization or certificate of formation, bylaws, operating
                  agreement or limited liability company agreement, or
                  partnership agreement of such party or any of its Controlled
                  Related Parties or of any material agreement or instrument to
                  which such party or any of its Controlled Related Parties is a
                  party or by which such party or any of its Controlled Related
                  Parties is or may be bound or to which any of its material
                  properties or assets is subject (other than any such conflict,

                  be bound, or (iv) will result in the creation or imposition of
                  any lien upon any of the material properties or assets of such
                  party or any of its Controlled Related Parties, which in any
                  such case could reasonably be expected to materially impair
                  such party's ability

                  material adverse effect on the consolidated financial
                  condition of each party or its Parent.

         (c)      Governmental Authorizations. Any registration, declaration or

                  Controlled Related Parties or any of their properties, assets
                  or businesses in any court or before or by any governmental
                  department, board, agency or instrumentality, domestic or

                  determined (or, in the case of an investigation could lead to
                  any action, suit or proceeding, which if adversely determined
                  could), reasonably be expected to materially impair such
                  party's ability to perform its obligations under this
                  agreement or to have a material adverse effect on the
                  consolidated financial condition of such party or its parent;
                  and such party or any of its Controlled Related Parties has
                  not received any currently effective notice of any default,

                  in default, under any applicable order, writ, injunction,

                  governmental department, board, agency or instrumentality,
                  domestic or foreign, or any arbitrator, which default could
                  reasonably be expected to materially impair such party's
                  ability to perform its obligations under this agreement or to
                  have a material adverse effect on the consolidated financial
                  condition of such party or its Parent.

the other party against and agrees to hold it harmless from any Loss incurred or
suffered by such other party arising out of or in connection with:

                  (i)      the material breach of any representation or warranty
                           made by such party in this agreement; and

                  (ii)     the material breach of any covenant or agreement by

                  Licensed Marks by Licensee; or (ii) the marketing, promotion,
                  advertisement, distribution, lease or sale by Licensee ( or

                  marketing materials have not been approved by Licensor prior
                  to the publication out of which such claims are alleged to
                  have arisen.

party hereto, and the obligations of each party shall not be subject to any
right of setoff or recoupment which such party may not or hereafter have against

to submit samples of such materials to Licensor for approval. Licensor shall
have fourteen (14) days from the date Licensor receives such materials to
approve or object to any such materials submitted to Licensor for review. In the
event Licensor does not object to such materials within such fourteen (14) day
period, such materials shall be deemed approved by Licensor. Thereafter,
Licensee shall not be obligated to submit to Licensor materials prepared in
accordance with the samples previously approved by Licensor and the Trademark
and Service Mark Usage Guidelines; provided, however, Licensee shall, at the
reasonable request of Licensor, continue to furnish samples of such marketing,
advertising and promotional materials to Licensor from time to time during the
term hereof at the request of Licensor.

         Section 10.3. Use of Similar Trademarks and Service Marks. Licensee

any language would be identified as the equivalent of the Licensed Marks or that
are otherwise confusingly similar to, or a colorable imitation of, the Licensed
Marks, whether during the term of this agreement or at any time following

Licensor's prior written approval (which approval will not be unreasonably

each party and shall use good faith efforts to coordinate their respective
campaigns in a manner that will maximize the advertising, marketing and
promotional efforts of the parties and be consistent with the Marketing
Communications Guidelines. Licensee shall not initiate any products or

by Licensee.

provided in Articles 7 and 8), and Licensee is not granted any right or
authority to assume or create any obligations for, on behalf of, or in the name

any debt or obligation on behalf of Licensor, or commit any act, make any
representation, or advertise in any manner that may adversely affect any right
of Licensor in or with respect to the Licensed Marks or be detrimental to

                  any Missouri State court sitting in the County of Jackson or
                  any Federal court of the United States of America sitting in
                  the Western District of Missouri, and any appellate court from
                  any such court, in any suit action or proceeding arising out

Securities proposed to be sold and will also specify the intended method of
disposition thereof. The Company shall give written notice of such registration
request to all other Holders of Registrable Securities within fifteen (15)
Business Days after the receipt thereof. Within ten (10) days after receipt by
any Holder of Registrable Securities of such notice from the Company, such
Holder may request in writing that such Holder's Registrable Securities be
included in such Registration Statement and the Company shall include in such
Registration Statement the Registrable Securities of any such Holder requested
to be so included (the "Included Securities"). Each such request by such other
Holders shall specify the number of Included Securities proposed to be sold and

occasions that the Holders may request the registration of their Registrable
Securities on a Form S-3 Registration Statement, or any successor registration
form that permits the prospectus to incorporate by reference subsequent periodic
reports filed by the Company.

offered and sold for the account of the Company and (iii) any equity securities
of the Company held by any Person having "piggy-back" registration rights
pursuant to any contractual obligation of the Company shall be included in a
Demand Registration. The inclusion of any such securities for the account of the
Company or any other Person shall be on the same terms as that of the
Registrable Securities.

     (b) Effective Registration. A Registration Statement will not be deemed to
have been effected as a Demand Registration unless it has been declared
effective by the SEC and the Company has complied in all material respects with
all of its obligations under this Agreement with respect thereto; provided,
however, that if, after such Registration Statement has become effective, the
offering of Registrable Securities pursuant to such Registration Statement is or
becomes the subject of any stop order, injunction or other order or requirement
of the SEC order, injunction or other order or requirement of the SEC or any
other governmental or administrative agency or court that prevents, restrains or
otherwise limits the sale of Registrable Securities pursuant to such
Registration Statement for any reason not attributable to any Holder
participating in such registration and such restraint is not lifted within sixty
(60) days after being imposed, such Registration Statement will be deemed not to
have been effected. If (i) a registration requested pursuant to this Section 2.1
is deemed not to have been effected or (ii) a Demand Registration does not
remain effective under the Securities Act until at least the earlier of (A) an
aggregate of six months after the effective date thereof or (B) the consummation
of the distribution by the Holders of all of the Registrable Securities covered
thereby, then such registration shall not count towards determining if the
Company has satisfied its obligation to three (3) Demand Registrations pursuant
to this Section 2.1. For purposes of calculating the six month period referred
to in the preceding sentence, any period of time during which such Registration
Statement was not in effect shall be excluded. The Holders of Registrable
Securities shall be permitted to withdraw all or any part of the Registrable
Securities from a Demand Registration at any time prior to the effective date of
such Demand Registration; provided, however, that should the Holders of
Registrable Securities remaining after such withdrawal own, individually or in
the aggregate, less than the Requisite Securities, the Company shall have the
right to terminate or withdraw any registration initiated by it under Section
2.1 prior to the effectiveness of such registration. Notwithstanding the
foregoing, if the Holders of at least the Requisite Securities request the
withdrawal of a Registration Statement after it is filed, such Registration
Statement will be deemed to have been a Demand Registration unless the Holders
of the Included Securities pay the Registration Expenses associated with such
Registration Statement unless such withdrawal is the result of a material
adverse change in the financial condition or results of operation of the
Company.

     (c) Underwritten Registrations. If any of the Registrable Securities
covered by a Demand Registration are to be sold in an underwritten offering, the
investment banker or investment bankers and manager or managers that will manage
the offering will be selected by the Holders of not less than a majority of the
Registrable Securities to be sold thereunder and will be reasonably acceptable
to the Company.




                                       5
<PAGE>   6

     No Holder of Registrable Securities may participate in any underwritten
registration pursuant to a Registration Statement filed under this Agreement
(whether a Demand Registration or a Piggy-Back Registration) unless such Holder
(a) agrees to (i) sell such Holder's Registrable Securities on the basis
provided in and in compliance with the underwriting arrangements and (ii) comply
with Rules 101, 102 and 104 of Regulation M promulgated under the Exchange Act
and (b) completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents reasonably required by
the investment bankers under the terms of such underwriting arrangements.

     (d) Priority in Demand Registration. In a registration pursuant to Section
2.1 hereof involving an underwritten offering, if the managing underwriter or
underwriters of such underwritten offering have informed, in writing, the
Company and the Selling Holders who have requested such Demand Registration or
who have sought inclusion therein that in such underwriter's or underwriters'
opinion the total number of securities which the Selling Holders and any other
Person entitled to participate in such registration pursuant to Section 2.1(a)
hereof intend to include in such offering is such as to adversely affect the
success of such offering, including the price at which such securities can be
sold, then the Company will be required to include in such registration only the
amount of securities which it is so advised should be included in such
registration. In such event, securities shall be registered in such registration
in the following order of priority: (i) first, the securities which have been
requested to be included in such registration by the Holders of Registrable
Securities, (ii) second, the securities of other Persons entitled to exercise
"piggy-back" registration rights pursuant to contractual commitments of the
Company (pro rata based on the amount of securities sought to be included in the
registration by such Persons), and (ii) third, provided that no securities
sought to be included by the Holders or any other Person sought to be included
therein have been excluded from such registration, securities to be offered and
sold for the account of the Company.

     If twenty-five percent (25%) or more of the Registrable Securities which
the Holders have requested to be included in a Registration Statement pursuant
to Section 2.1 hereof have been excluded from such Registration Statement
pursuant to the provisions of the foregoing paragraph, then such registration
shall not count towards determining whether the Company has satisfied its
obligation to effect three (3) Demand Registrations pursuant to Section 2.1
hereof.

     Section 2.2. Piggy-Back Registration.

     (a) General. If at any time after the sixtieth (60th) day prior to the
second anniversary of the date of this Agreement the Company proposes to file a
Registration Statement under the Securities Act with respect to an offering by
the Company for its own account, other than (i) a Registration Statement on Form
S-4 or S-8 (or any substitute form that may be adopted by the SEC or other form
of limited purpose), (ii) a Registration Statement filed in connection with an
exchange offer or offering of securities solely to the Company's existing
security holders, or (iii) a Registration Statement filed pursuant to the
exercise of "demand" registration rights of existing security holders pursuant
to a contractual commitment of the Company, then the Company shall give written
notice of such proposed filing to the Holders of Registrable Securities as soon
as practicable (but in no event




                                       6
<PAGE>   7

fewer than thirty (30) days before the anticipated filing date or twenty (20)
days before the anticipated filing date if the Company is subject to filing
reports under the Exchange Act and able to use Form S-3 under the Securities
Act), and such notice shall offer such Holders the opportunity to register such
number of shares of Registrable Securities as each such Holder may request in
writing not later than five (5) days prior to the anticipated filing date of the
Registration Statement (so long as the Holder has received such written notice
in accordance with the foregoing time periods from the Company) (which request
shall specify the Registrable Securities intended to be disposed of by such
Selling Holder and the intended method of distribution thereof) (a "Piggy-Back
Registration"). The Company shall have no obligation to effect such Piggy-Back
Registration unless Holders request in writing to include in the Piggy-Back
Registration, individually or in the aggregate, not less than that number of
Registrable Securities that equals the Requisite Securities. The Company shall
use commercially reasonable efforts to keep such Piggy-Back Registration
continuously effective under the Securities Act until the consummation of the
distribution by the Holders of all of the Registrable Securities covered
thereby. The Company shall use its commercially reasonable efforts to cause the
managing underwriter or underwriters, if any, of such proposed offering to
permit the Registrable Securities requested to be included in a Piggy-Back
Registration to be included on the same terms and conditions as any similar
securities of the Company or any other security holder included therein, subject
to the restrictions set forth in Section 2.2(b), and to permit the sale or other
disposition of such Registrable Securities in accordance with the intended
method of distribution thereof. Any Selling Holder shall have the right to
withdraw its request for inclusion of its Registrable Securities in any
Registration Statement pursuant to this Section 2.2 by giving timely written
notice to the Company of its request to withdraw. The Company may withdraw a
Piggy-Back Registration at any time prior to the time it becomes effective or
the Company may elect to delay the registration; provided, however, that the
Company shall give prompt written notice thereof to participating Selling
Holders.

     No Registration effected under this Section 2.2, and no failure to effect a
registration under this Section 2.2, shall relieve the Company of its obligation
to effect a registration pursuant to Section 2.1 hereof, and no failure to
effect a registration under this Section 2.2 and to complete the sale of
securities registered thereunder in connection therewith shall relieve the
Company of any other obligation under this Agreement.

     (b) Priority in Piggy-Back Registration. In a registration pursuant to
Section 2.2 hereof involving an underwritten offering, if the managing
underwriter or underwriters of such underwritten offering have informed, in
writing, the Company and the Selling Holders requesting inclusion in such
offering that in such underwriter's or underwriters' opinion the total number of
securities which the Company, the Selling Holders and any other Persons desiring
to participate in such registration intend to include in such offering is such
as to adversely affect the success of such offering, including the price at
which such securities can be sold, then the Company will be required to include
in such registration only the amount of securities which it is so advised should
be included in such registration. In such event, securities shall be registered
in such offering in the following order of priority: (i) first, the securities
which the Company proposes to register, (ii) second, provided that no securities
sought to be included by the Company have been excluded from such registration,
the




                                       7
<PAGE>   8

securities which have been requested to be included in such registration by the
Holders of Registrable Securities and other Persons entitled to exercise
"piggy-back" registration rights pursuant to contractual commitments of the
Company (pro rata based on the amount of securities held by the Holders of
Registrable Securities requesting such inclusion and such Persons).

     If, as a result of the provisions of this Section 2.2(b), any Selling
Holder shall not be entitled to include all Registrable Securities in a
Piggy-Back Registration that such Selling Holder has requested to be included,
such Selling Holder may elect to withdraw his request to include Registrable
Securities in such registration.

     (c) Underwritten Registrations. If any of the Registrable Securities
covered by a Piggy-Back Registration are to be sold in an underwritten
offering, the investment banker or investment bankers and manager or managers
that will manage the offering will be selected by the Company.

     Section 2.3. Limitations and Conditions to Obligations Under Registration
Covenants.

     (a) The Company's obligations shall be subject to the obligations of the
Selling Holders, which the Selling Holders acknowledge, to furnish all
information and materials required of such Selling Holders and to take any and
all actions required of such Selling Holders to permit the Company to comply
with all applicable requirements of the SEC and to obtain any acceleration of
the effective date of such Registration Statement.

     (b) Subject to the next sentence of this paragraph, the Company shall be
entitled to postpone the filing or effectiveness of any Registration Statement
otherwise required to be prepared, filed and made effective by it pursuant to
Section 2.1 or 2.2 hereunder; provided, however, that the duration of such
postponement may not exceed the earlier to occur of (A) fifteen (15) days after
the cessation of the circumstances described in the next sentence of this
paragraph on which such postponement is based or (B) ninety (90) days after the
date of the determination of the Board of Directors referred to in the next
sentence. Such postponement may be effected only if the Board of Directors of
the Company makes a reasonable and good faith determination that the filing or
effectiveness of such Registration Statement would materially impede, delay or
interfere with any material financing, offer or sale of securities, acquisition,
corporate reorganization or other significant transaction involving the Company
or any of its Subsidiaries which material financing, offer or sale of
securities, acquisition, corporate reorganization or other significant
transaction is under active consideration at the time of such postponement;
provided, however, that the Company shall not be entitled to such postponement
more than once in any twelve-month period. If the Company shall take any such
action with respect to a Registration Statement it shall, as promptly as
possible, deliver a certificate signed by the Chief Executive Officer or
President of the Company to the Selling Holders as to such determination, and
the Selling Holders shall have the right, upon the affirmative vote of the
Holders of not less than a majority of the Registrable Securities to be included
in such Registration Statement, to withdraw the request for registration by
giving written notice to the Company within ten (10) days after the receipt of
such notice. Any Demand Registration as to which the withdrawal election
referred to in the preceding sentence has been effected shall not be counted





                                       8
<PAGE>   9

for purposes of the three Demand Registrations the Company is required to effect
pursuant to Section 2.1 hereof.

     (c) The Company shall not be required by this Agreement to file a
registration statement with respect to a Demand Registration for a Holder during
the period starting with the date of filing of, and within ninety (90) days
immediately following, the effective date of any Registration Statement under
the Securities Act pertaining to a firmly underwritten offering of equity
securities of the Company for its own account so long as such Holder has been
given the opportunity to include in such Registration Statement such Holder's
Registrable Securities pursuant to Section 2.2 hereof and not been denied such
opportunity under Section 2.2 (b) or otherwise.

     Section 2.4. Restrictions on Sale by the Company and Others. The Company
covenants and agrees that (i) during the 10-day period prior to, and during the
90-day period beginning on, the commencement of any underwritten offering of
Registrable Securities pursuant to a Demand Registration which has been
requested pursuant to this Agreement, it shall not, and shall not cause or
permit any of its Subsidiaries to, effect any public sale or distribution of any
securities of the same class as any of the Registrable Securities or any
securities convertible into or exchangeable or exercisable for such securities
(or any option or other right for such securities), other than any Common Stock
and/or options, Warrants or other Common Stock purchase rights, and the Common
Stock issued pursuant to such option, Warrants or other rights, to employees,
officers or directors of, or consultants or advisors to the Company or any
Subsidiary pursuant to stock purchase or stock option plans or other
arrangements that are approved by the Board of Directors of the Company, prior
to the Company or any of its Subsidiaries publicly announcing its intention to
effect any such public sale or distribution; and (ii) the Company will not, and
the Company will not cause or permit any of its Subsidiaries to, after the date
hereof, enter into any agreement or contract that conflicts with or limits or
prohibits the full and timely exercise by the Holders of Registrable Securities
of the rights herein to request a Demand Registration or to join in any
Piggy-Back Registration subject to the other terms and provisions hereof.

     Section 2.5. Rule 144 and Rule 144A. The Company covenants that it will
file the reports required to be filed by it under the Securities Act and the
Exchange Act and the rules and regulations adopted by the SEC thereunder in a
timely manner and, if at any time the Company is not required to file such
reports, it will, upon the request of any Holder or beneficial owner of
Registrable Securities, make available such information necessary to permit
sales pursuant to Rule 144A under the Securities Act. The Company further
covenants that it will take such further action as any Holder of Registrable
Securities may reasonably request, all to the extent required from time to time
to enable such Holder to sell Registrable Securities without registration under
the Securities Act within the limitation of the exemptions provided by (a) Rule
144(k) and Rule 144A under the Securities Act, as such Rules may be amended from
time to time, or (b) any similar rule or regulation hereafter adopted by the SEC
(it being expressly understood that the foregoing shall not create any
obligation on the part of the Company to file periodic reports or other reports
under the Exchange Act at any time that it is not then required to file such
reports pursuant to the Exchange Act). Upon the reasonable request of any Holder
of Registrable Securities, the Company will in a timely manner





                                       9
<PAGE>   10

deliver to such Holder a written statement as to whether it has complied with
such information requirements.

     Section 3. Registration Procedures. In connection with the obligations of
the Company with respect to any Registration Statement pursuant to Sections 2.1
and 2.2, hereof, the Company shall, except as otherwise provided:

     (a) Prepare and file with the SEC as soon as practicable each Registration
Statement (but in any event on or prior to the date of filing thereof required
under this Agreement) and use commercially reasonable efforts to cause such
Registration Statement to become effective and remain effective as provided
herein; provided, however, that before filing any such Registration Statement or
any Prospectus (for registrations pursuant to Sections 2.1 and 2.2 hereof) or
any amendments or supplements thereto (only for registrations pursuant to
Section 2.1 hereof), the Company shall make available to the Holders of the
Registrable Securities covered by such Registration Statement, and the managing
underwriter or underwriters, if any, copies of all such documents proposed to be
filed, which documents will be subject to the review and comment of such Holders
and underwriters in connection with such sale, if any, for a period of at least
five (5) Business Days, and the Company will not file any such Registration
Statement or amendment or supplement to any such Registration Statement
(including all such documents incorporated by reference) to which the Holders of
the Registrable Securities covered by such Registration Statement or the
underwriters in connection with such sale, if any, shall reasonably object
within five (5) Business Days after the receipt thereof.

     (b) Prepare and file with the SEC such amendments and post-effective
amendments to the Registration Statement as may be necessary to keep such
Registration Statement continuously effective for the time periods prescribed
hereby; cause the related Prospectus to be supplemented by any required
prospectus supplement, and as so supplemented to be filed pursuant to Rule 424
(or any similar provisions then in force) promulgated under the Securities Act;
and comply with the provisions of the Securities Act, the Exchange Act and the
rules and regulations of the SEC promulgated thereunder applicable to it with
respect to the disposition of all securities covered by such Registration
Statement as so amended or in such prospectus as so supplemented.

     (c) Notify the Holders of Registrable Securities, their counsel and the
managing underwriter or underwriters, if any, promptly (but in any event within
two (2) Business Days), and confirm such notice in writing, (i) when a
Prospectus or any prospectus supplement or post-effective amendment has been
filed, and, with respect to a Registration Statement or any post-effective
amendment, when the same has become effective (including in such notice a
written statement that any Holder may, upon request, obtain, without charge, one
conformed copy of such Registration Statement or post-effective amendment
including financial statements and schedules and exhibits), (ii) of the issuance
by the SEC of any stop order suspending the effectiveness of such Registration
Statement or any preliminary prospectus or the initiation or threatening of any
proceedings for that purpose, (iii) of the receipt by the Company of any
notification with respect to (A) the suspension of the qualification or
exemption from qualification of the Registration Statement or any of the
Registrable Securities covered thereby for offer or sale in any jurisdiction, or
(B) the initiation of any





                                       10
<PAGE>   11

proceeding for such purpose, (iv) of the happening of any event, the existence
of any condition or information becoming known to the Company that requires the
making of any changes in such Registration Statement, Prospectus or documents so
that, in the case of such Registration Statement, it will conform in all
material respects with the requirements of the Securities Act and it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
not misleading, and that in the case of the Prospectus, it will conform in all
material respects with the requirements of the Securities Act and it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
not misleading, and (v) of the Company's reasonable determination that a
post-effective amendment to such Registration Statement would be appropriate.

     (d) Use commercially reasonable efforts to prevent the issuance of any
order suspending the effectiveness of the Registration Statement or of any order
preventing or suspending the use of a Prospectus or suspending the qualification
(or exemption from qualification) of any of the Registrable Securities covered
thereby for sale in any jurisdiction, and, if any such order is issued, to
obtain the withdrawal of any such order at the earliest practicable moment.

     (e) If requested by the managing underwriter or underwriters, if any, or
the Holders of a majority of the Registrable Securities being sold in connection
with an underwritten offering (only for registrations pursuant to Section 2.1
hereof), (i) promptly incorporate in a prospectus supplement or post-effective
amendment such information as the managing underwriter or underwriters, if any,
or such Holders reasonably request to be included therein to comply with
applicable law, (ii) make all effective amendment as soon as practicable after
the Company has received notification of the matters to be incorporated in such
prospectus supplement or post effective amendment, and (iii) supplement or make
amendments to such Registration Statements.

     (f) Furnish to each Holder of Registrable Securities who so requests and to
counsel for the Holders of Registrable Securities and each managing underwriter,
if any, without charge, upon request, one conformed copy of the Registration
Statement and each post effective amendment thereto, including financial
statements and schedules, and of all documents incorporated or deemed to be
incorporated therein by reference and all exhibits (including exhibits
incorporated by reference).

     (g) Deliver to each Holder of Registrable Securities, their counsel and
each underwriter, if any, without charge, as many copies of each Prospectus
(including each form of prospectus) and each amendment or supplement thereto as
such Persons may reasonably request; and, subject to the last paragraph of this
Section 3, the Company hereby consents to the use of such Prospectus and each
amendment or supplement thereto by each of the Holders of Registrable Securities
and the underwriter or underwriters or agents, if any in connection with the
offering and sale of the Registrable Securities covered by such Prospectus and
any amendment or supplement thereto.

     (h) Prior to any offering of Registrable Securities, to register or
qualify, and cooperate with the Holders of Registrable Securities, the
underwriter or underwriters, if any, and their




                                       11
<PAGE>   12

respective counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of, such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as the managing underwriter or
underwriters reasonably request in writing, or, in the event of a
non-underwritten offering, as the Holders of a majority of the Registrable
Securities being sold may request; provided, however, that where Registrable
Securities are offered other than through an underwritten offering, the Company
agrees to cause its counsel to perform Blue Sky investigations and file
registrations and qualifications required to be filed pursuant to this Section
3(h); keep such registration or qualification (or exemption therefrom) effective
during the effectiveness period and do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
securities covered thereby; provided, however, that the Company will not be
required to (A) qualify generally to do business in any jurisdiction where it
has not then so qualified, (B) take any action that would subject it to general
service of process in any such jurisdiction where it is not then so subject or
(C) become subject to taxation in any jurisdiction where it is not then so
subject.

     (i) Cooperate with the Holders of Registrable Securities and the managing
underwriter or underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold, which
certificates shall not bear any restrictive legends whatsoever and shall be in a
form eligible for deposit with The Depository Trust Company ("DTC"); and enable
such Registrable Securities to be in such denominations and registered in such
names as the managing underwriter or underwriters, if any, or Holders may
reasonably request at least two (2) Business Days prior to any sale of
Registrable Securities in a firm commitment underwritten public offering.

     (j) Pay all Registration Expenses in connection with the registrations
requested pursuant to Sections 2.1 and 2.2 hereof. Each Holder of Registrable
Securities shall pay all underwriting discounts and commissions and transfer
taxes, if any, relating to the sale or disposition of such Holder's Registrable
Securities pursuant to a Registration Statement requested pursuant to Section
2.1.

     (k) Upon the occurrence of any event contemplated by Section 3(c)(iv) or
3(c)(v) above, as promptly as practicable prepare a supplement or post-effective
amendment to the Registration Statement or a supplement to the related
Prospectus or any document incorporated or deemed to be incorporated therein by
reference, and, subject to Section 3(a) hereof, file such with the SEC so that,
as thereafter delivered to the purchasers of Registrable Securities being sold
thereunder, such Prospectus will not contain an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading.

     (l) Prior to the effective date of a Registration Statement, (i) provide
the registrar for the Registrable Securities with certificates for such
securities in a form eligible for deposit with DTC and (ii) provide a CUSIP
number for such securities.





                                       12
<PAGE>   13

     (m) If the offering provided for herein is conducted by means of an
underwriting, enter into an underwriting agreement in form, scope and substance
as is customary in underwritten offerings and take all such other actions as are
reasonably requested by the managing underwriter or underwriters in order to
expedite or facilitate the registration or disposition of such Registrable
Securities in any underwritten offering to be made of the Registrable Securities
in accordance with this Agreement, and in such connection, (i) make such
representations and warranties to the underwriter or underwriters, with respect
to the business of the Company and its Subsidiaries, and the Registration
Statement, Prospectus and documents, if any, incorporated or deemed to be
incorporated by reference therein, in each case, in form, substance and scope as
are customarily made by issuers to underwriters in underwritten offerings, and
confirm the same if and when requested; (ii) use reasonable efforts to obtain an
opinion of counsel to the Company, addressed to the underwriter or underwriters
covering the matters customarily covered in opinions requested in underwritten
offerings and such other matters as may be reasonably requested by underwriters;
(iii) use reasonable efforts to obtain "cold comfort" letters from the
independent certified public accountants of the Company (and, if applicable, the
Subsidiaries of the Company) and, if necessary, any other independent certified
public accountants of any Subsidiary of the Company or of any business acquired
by the Company for which financial statements and financial data are, or are
required to be, included in the Registration Statement, addressed to each of the
underwriters, such letters to be in customary form and covering matters of the
type customarily covered in "cold comfort" letters in connection with
underwritten offerings and such other matters as reasonably requested by the
managing underwriter or underwriters and as permitted by the underwriting
agreement is entered into, the same shall contain customary indemnification
provisions and procedures with respect to all parties to be indemnified pursuant
to said Section. The above shall be done at each closing under such underwriting
agreement, or as and to the extent required thereunder.

     (n) Make available for inspection by a representative of the Holders of
Registrable Securities being sold, any underwriter participating in any such
disposition of Registrable Securities, if any, and any attorney or account
retained by such representative of the Holders or underwriter (collectively, the
"Inspectors"), at the offices where normally kept, during reasonable business
hours, at the Inspector's expense, all financial and other records, pertinent
corporate documents and properties of the Company and its Subsidiaries as
reasonably requested by the Inspector, and cause the officers, directors and
employees of the Company and its Subsidiaries to supply all information in each
case reasonably requested by any such Inspector in connection with such
Registration Statement; provided, however, that all such information shall be
kept confidential by such Inspector and shall not be used for any purpose other
than as contemplated hereby, except to the extent that (i) the disclosure of
such information is necessary or advisable to avoid or correct a misstatement or
omission in the Registration Statement or in any Prospectus; provided, however,




                                       13
<PAGE>   14

that prior notice is given to the Company, and the Company's legal counsel
and such Holder's legal counsel concur that disclosure is required, (ii) the
release of such information is ordered pursuant to a subpoena or other order
from court of competent jurisdiction, (iii) disclosure of such information is
necessary or advisable in connection with any action, claim, suit or proceeding,
directly or indirectly, involving or potentially involving such Inspector and
arising out of, based upon, relating to or involving this Agreement or any of
the transactions contemplated hereby or arising hereunder; provided, however,
that prior notice shall be provided as soon as practicable to the Company of the
potential disclosure of any information by such Inspector pursuant to clauses
(ii) or (iii) of this sentence to permit the Company to obtain a protective
order (or waive the provisions of this paragraph (n)) and that such Inspector
shall take all actions as are reasonably necessary to protect the
confidentiality of such information (if practicable) to the extent such action
is otherwise not inconsistent with, an impairment of or in derogation of the
rights and interests of the Holder or any Inspector, or (iv) such information
has been made generally available to the public.

     (o) Comply with all applicable rules and regulations of the SEC and make
generally available to its security holders earnings statements satisfying the
provisions of Section 10(a) of the Securities Act and Rule 158 thereunder (or
any similar rule promulgated under the Securities Act) no later than forty-five
(45) days after the end of any 12-month period (or ninety (90) days after the
end of any 12-month period if such period is a fiscal year) (i) commencing at
the end of any fiscal quarter in which Registrable Securities are sold to an
underwriter or to underwriters in a firm commitment or best efforts underwritten
offering and (ii) if not sold to an underwriter or to underwriters in such an
offering, commencing on the first day of the first fiscal quarter of the Company
after the effective date of the relevant Registration Statement, which
statements shall cover said 12-month periods.

     (p) Use commercially reasonable efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on each securities
exchange, if any, on which similar securities issued by the Company are then
listed.

     (q) Cooperate with the Selling Holders of Registrable Securities to
facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be sold and not bearing any restrictive legends and
registered in such names as the Selling Holders may reasonably request at least
two (2) Business Days prior to the closing of any sale of Registrable
Securities.

     (r) Furnish, at the request of any Holder requesting registration of
Registrable Securities pursuant to this Section 3, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to this Section 3, if such securities are being
sold through underwriters, or, if such securities are not being sold through
underwriters, on the date that the Registration Statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an Underwritten Offering,
addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a letter dated such date, from
the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

     (s) Cooperate and assist in any filings required to be made with the
National Association of Securities Dealers, Inc. ("NASD") and in the performance
of any due diligence investigation by




                                       14
<PAGE>   15

any underwriter (including any "qualified independent underwriter") that is
required to be retained in accordance with the rules and regulations of the
NASD.

     Each seller of Registrable Securities as to which any registration is being
effected agrees, as a condition to the registration obligations with respect to
such seller provided herein, to furnish to the Company such information
regarding such seller and the distribution of such Registrable Securities as the
Company may, from time to time, reasonably request in writing to comply with the
Securities Act and other applicable law. The Company may exclude from such
registration the Registrable Securities of any seller for so long as such seller
fails to furnish such information within a reasonable time after receiving such
request. If the identity of a seller of Registrable Securities is to be
disclosed in the Registration Statement, such seller shall be permitted to
include all information regarding such seller as it shall reasonably request.

     Each Holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 3(c)(ii), 3(c)(iii),
3(c)(iv), or 3(c)(v) hereof, such Holder will forthwith discontinue disposition
of such Registrable Securities covered by the Registration Statement or
Prospectus until such Holder's receipt of the copies of the supplemented or
amended Prospectus contemplated by Section 3(k) hereof, or until it is advised
in writing by the Company that the use of the applicable prospectus may be
resumed, and has received copies of any amendments or supplements thereto, and,
if so directed by the Company, such Holder will, at the Company's expense,
deliver to the Company all copies, other than permanent file copies, then in
such Holder's actual possession of the Prospectus covering such Registrable
Securities current at the time of receipt of such notice; provided, however,
that nothing herein shall create any obligation on the part of any Holder to
undertake unreasonable efforts to retrieve or return any such Prospectus not
within the actual possession or control of such Holder. In the event the Company
shall give any such notice, the period of time for which a Registration
Statement is required thereunder to be effective shall be extended by the number
of days during such periods from and including the date of the giving of such
notice to and including the date when each seller of Registrable Securities
covered by such Registration Statement shall have (x) received the copies of the
supplemented or amended Prospectus contemplated by Section 3(k) hereof or (y)
been in advised in writing by the Company that the use of the applicable
prospectus may be resumed.

     Section 4. Indemnification and Contribution.

     (a) The Company agrees to indemnify and hold harmless each Holder, its
officers and directors, and each Person, if any, who controls such Holder within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act, or is under common control with, or is controlled by, such Holder,
from and against all losses, claims, damages and liabilities (including, without
limitation, and subject to clause (c) of this Section 4 below, the reasonable
legal fees and other reasonable out-of-pocket expenses actually incurred by any
Holder or any such controlling or affiliated Person in connection with any suit,
action or proceeding or any claim asserted), caused by, arising out of or based
upon any untrue statement or alleged untrue statement of a material fact






                                       15
<PAGE>   16

contained in any Registration Statement (or any amendment thereto) pursuant to
which the sale of Registrable Securities was registered under the Securities
Act, or caused by any omission or alleged omission to state in any such
Registration Statement a material fact required to be stated therein or
necessary to make the statements therein not misleading, or caused by any untrue
statement or alleged untrue statement of a material fact contained in any
preliminary prospectus or Prospectus (as amended or supplemented if the Company
shall have furnished any amendments or supplements thereto), or caused by any
omission or alleged omission to state in any such preliminary prospectus or
Prospectus a material fact required to be stated in any such preliminary
prospectus or Prospectus or necessary to make the statements in any such
preliminary prospectus or Prospectus in light of the circumstances under which
they were made not misleading, except insofar as such losses, claims, damages or
liabilities are caused by any such untrue statement or omission or alleged
untrue statement or omissions made in reliance upon and in conformity with
information relating to any Holder furnished to the Company in writing by such
Holder expressly for use in any such Registration Statement, Preliminary
Prospectus or Prospectus; provided, however, that the Company shall not be
required to indemnify any such Person if such untrue statement or omission or
alleged untrue statement or omission was contained or made in any preliminary
prospectus and corrected in the Prospectus, or any amendment or supplement
thereto and the Prospectus does not contain any other untrue statement or
omission or alleged untrue statement or omission of a material fact that was the
subject matter of the related proceeding and any such loss, liability, claim,
damage or expense suffered or incurred by such indemnified Person resulted from
any action, claim or suit by any Person who purchased Registrable Securities
which are the subject thereof from such indemnified Person and it is established
in the related proceeding that such indemnified Person failed to deliver or
provide a copy of the Prospectus (as amended or supplemented) to such Person
with or prior to the confirmation of the sale of such Registrable Securities
sold to such Person if required by applicable law, unless such failure to
deliver or provide a copy of the Prospectus (as amended or supplemented) was a
result of noncompliance by the Company with Section 3 hereof or as a result of
the failure of the Company to provide such Prospectus.

     (b) Each Holder agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, its officers who sign any Registration
Statement, and each Person, if any, who controls the Company within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Company to such Holder, but
only with reference to information furnished by such Holder to the Company
expressly for use in any Registration Statement (or any amendment thereto) or
any Prospectus (or any amendment or supplement thereto). The liability of any
Holder under this paragraph shall in no event exceed the proceeds received by
such Holder from sales of Registrable Securities giving rise to such
obligations.

     (c) In case any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be instituted involving any
Person in respect of which indemnity may be sought pursuant to either paragraph
(a) or (b) above, such Person (the "Indemnified Party") shall promptly notify
the Person against which such indemnity may be sought (the "Indemnifying Party")
in writing and the Indemnifying Party, upon request of the Indemnified Party,
shall retain counsel reasonably satisfactory to the Indemnified Party to
represent the Indemnified Party and any





                                       16
<PAGE>   17

others the Indemnifying Party may reasonably designate in such proceeding and
shall pay the reasonable fees and expenses actually incurred of such counsel
relating to such proceeding; provided, however, that the failure to so notify
the Indemnifying Party shall not relieve it of any obligation or liability which
it may have thereunder or otherwise unless the Indemnifying Party has been
materially prejudiced by such failure. In any such proceeding, any Indemnified
Party shall have the right to retain its own counsel, but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party unless (i) the
Indemnifying Party and the Indemnified Party shall have mutually agreed to the
contrary, (ii) the Indemnifying Party shall have failed to retain within a
reasonable period of time counsel reasonably satisfactory to such Indemnified
Party or parties or (iii) the named parties to any such proceeding (including
any impleaded parties) include both such Indemnified Party or parties and the
Indemnifying Parties or any affiliate of the Indemnifying Parties or such
Indemnified Parties and counsel for the Indemnifying Parties or Indemnified
Parties shall have concluded such written opinion that representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between the Indemnifying Party or parties and the
Indemnified Party or parties. It is understood that the Indemnifying Parties
shall not, in connection with any one such proceeding or separate but
substantially similar or related proceedings in the same jurisdiction, arising
out of the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm or attorneys (together with appropriate
local counsel) at any time for such Indemnified Party or parties and that all
such fees and expenses shall be reimbursed within reasonable time of the request
after the incurrence thereof. Any such separate firm for the Holders and such
control Persons of the Holders shall be designated in writing by Holders who
sold a majority in interest of Registrable Securities sold by all such Holders
and shall be reasonably acceptable to the Company and any such separate firm for
the Company, its directors, its officers and such control Persons of the Company
shall be designated in writing by the Company. The Indemnifying Party shall not
be liable for any settlement of any proceeding effected without its prior
written consent (which consent shall not be unreasonably withheld or delayed)
but if settled with such consent or if there be a final judgment for the
plaintiff, the Indemnifying Party agrees to indemnify and hold harmless the
Indemnified Party from and against any loss or liability by reason of such
settlement or judgment. No Indemnifying Party shall, without the prior written
consent of the Indemnified Party (which consent shall not be unreasonably
withheld), effect any settlement or compliance of any pending or threatened
proceeding in respect of which any Indemnified Party is or could have been a
party, or indemnity could have been sought thereunder by such Indemnified Party,
unless such settlement or compliance involves only the payment of money damages
that are actually paid by the Indemnifying Party or includes an unconditional
written release of such Indemnified Party in form and substance reasonably
satisfactory to such Indemnified Party of such Indemnified Party from all
liability or claims that are the subject matter of such proceeding.

     (d) To the extent the indemnification provided for a paragraph (a) or (b)
of this Section 4 is unavailable to, or insufficient to hold harmless, an
Indemnified Party in respect of any losses, claims, damages or liabilities, then
each Indemnifying Party under such paragraph, in lieu of indemnifying such
Indemnified Party thereunder and in order to provide for just and equitable
contribution, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such losses, claims, damages or liabilities in such losses,
claims, damages or liabilities in such





                                       17
<PAGE>   18

proportion as is appropriate to reflect (i) the relative benefits received by
the Company on the one hand and the Holders on the other hand from the offering
of such Registrable Securities or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, not only such relative benefits but
also the relative fault of the Company on the one hand and the Holders on the
other hand in connection with the statements or omissions or alleged statements
or omissions that resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Holders on the other shall be deemed to be in the same proportion as the
total proceeds from the offering (net of discounts and commissions but before
the deducting expenses) received by the Company bears to the total proceeds
received by such Holder from the sale of Registrable Securities, as the case may
be. The relative fault of the Company on the one hand and the Holders on the
other hand shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or by the Holders and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission,
and any other equitable considerations appropriate in the circumstances.

     (e) The Company and each Holder agree that it would not be just or
equitable if contribution pursuant to this Section 4 were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in Section 4(d) above. The amount paid
or payable by an Indemnified Party is a result of the losses, claims, damages
and liabilities referred to in Section 4(d) above shall be deemed to include,
subject to the limitations set forth above, any reasonable legal or other
expense actually incurred by such Indemnified Party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 4, in no event shall a Holder be required to
contribute any amount in excess of the amount by which proceeds received by such
Holder from sales of Registrable Securities exceeds the amount of any damages
that such Holder has otherwise been required to pay or has paid by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation. The remedies provided
for in this Section 4 are not exclusive and shall not limit any rights or
remedies which may otherwise be available to any Indemnified Party at law or in
equity.

     (f) Any losses, claims, damages, liabilities or expenses for which an
Indemnified Party is entitled to indemnification or contribution under this
Section 4 shall be paid by the Indemnifying Party to the Indemnified Party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 4 and the
representations and warranties of the Company set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Holder or any Person who controls a
Holder, the Company, their respective directors or officers or any Person
controlling the Company and (ii) any termination of this Agreement.

     Section 5. Miscellaneous.

     (a) No Inconsistent Agreements. The Company represents and warrants to the
Holders that it has not entered into nor will the Company on or after the date
of this Agreement enter into, or cause or permit any of its Subsidiaries to
enter into, any agreement which conflicts with or limits or prohibits the
exercise of the rights granted to the Holders of Registrable Securities in this
Agreement. The rights granted to the Holders hereunder do not in any way
conflict with or limit or prohibit the exercise of any rights granted to the
holders of the Company's other issued and outstanding securities, if any, under
such agreements.

     (b) Assumption of Rights.

         (i) The rights of each Holder under this Agreement shall be assignable;
provided, however, that the Company is given written notice at the time of such
assignment stating the name and address of the assignee and identifying the
securities with respect to which the rights and benefits hereunder are being
assigned and such assignee expressly agrees in writing with the Company and
other Holders of Registrable Securities to be bound by and to comply with all
applicable provisions of this Agreement, whereupon such person or entity shall
have the benefits of, and shall be subject to the restrictions contained in,
this Agreement with respect to such securities. Any assignment pursuant to this
Section 5 shall not relieve, release or otherwise discharge the Holder effecting
such assignment from its obligations under this Agreement.

         (ii) The Company may not assign this Agreement in whole or in part to
any other person without the prior written consent of a majority of the Holders
of then outstanding Warrants and Registrable Securities.

     (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given without the consent of the Company and
the prior written consent of Holders of not less than a majority in number of
the then outstanding Warrants and Registrable Securities not resold to the
public for the purpose of adding any provision to or changing in any manner or
eliminating any of the provisions of the Agreement or modifying in any manner
the rights of the Holders of the outstanding Warrants; provided, however, that
Section 4 hereof and this Section 5(c) may not be amended, modified or
supplemented without the prior written consent of each Holder (including any
Person who was a Holder of Registrable Securities disposed of pursuant to any
Registration Statement) affected by such amendment, modification of supplement.
Notwithstanding the foregoing, a waiver or consent to departure from the
provisions hereof that relates exclusively to the rights of Holders of
Registrable Securities whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect, impair,
limit or compromise the rights of other Holders of Registrable Securities may be
given the Company by the Holders of not less than a majority of the Registrable
Securities proposed to be sold by such Holders pursuant to such Registration
Statement.

     (d) Notices to Holders and Company. All notices and other communications
provided herein (including, without limitation, any waivers or consents under
this Agreement) shall be given or made by telecopy, telegraph, cable or
otherwise in writing (each communication given by any such




                                       19

means to be deemed "in writing" for purposes of this Agreement) and telecopies,
telegraphed, cabled, mailed or delivered to the intended recipient at the
address for such party following hereafter or, as to any party, at such other
addresses as shall be designated by such party in a notice to the others. Except

personally delivered or, (ii) in the case of transmission by telecopy, when
telecopied (with confirmation) and mailed (with same day post-mark) certified
mail, return receipt requested or (iii) in the case of a mailed notice, three
days after deposit with the United States Post Office, by registered or
certified mail, return receipt requested, in each case given or addressed as

                           Company from time to time.

     (e) Successors and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
agreement, subsequent Holders. If any transferee of any Holder shall acquire
Warrants and/or Registrable Securities, whether by operation of law or
otherwise, such Warrants and/or Registrable Securities shall be held subject to
all of the terms of this Agreement, and by taking and holding such Warrants
and/or Registrable Securities such Person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement and such Person shall be entitled to receive the benefits hereof.

     (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

     (g) Headings. The heading in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

     (h) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE
AND PERFORMED WHOLLY WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES
OF CONFLICTS OF LAW.

     (i) Severability. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the




                                       21
<PAGE>   22

terms, provisions, covenants and restrictions set forth herein shall remain in
full force and effect and shall in no way be affected, impaired or invalidated,
and the parties hereto shall use commercially reasonable efforts to find and
employ an alternative means to achieve the same or substantially the same result
as that contemplated by such term, provision, covenant or restriction. It is
hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restrictions
without including any of such that may be hereafter declared invalid, illegal,
void or unenforceable.

     (j) Entire Agreement. This Agreement, together with the Warrant Agreement
and Credit Agreement, is intended by the parties as a final expression of their
agreement, and is intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto in respect of the subject
matter contained herein and therein. This Agreement, together with the Warrant
Agreement and Credit Agreement, supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

     (k) Attorneys' Fees. As between the parties to this Agreement, in any
action or proceeding brought to enforce any provision of this Agreement, or
where any provision hereof is validly asserted as a defense, the successful
party shall be entitled to recover reasonable attorneys' fees in addition to its
costs and expenses and any other available remedy.

     (l) Securities Held by the Company or its Affiliates. Whenever the consent
or approval of Holders of a specified percentage of Registrable Securities or
Warrants is required thereunder, Registrable Securities or Warrants held by the
Company or any of its affiliates (as such term is defined in Rule 405 under the
Securities Act) shall not be counted (in either the numerator or the
denominator) in determining whether such consent or approval was given by the
Holders of such required percentage.

     (m) Remedies. In the event of a breach by the Company of any of its
obligations under this Agreement, each Holder, in addition to being entitled to
exercise all rights provided herein, or granted by law, including recovery of
damages, will be entitled to specific performance of its rights under this
Agreement. The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of any of the
provisions of this Agreement.

     The Holders are the third-party beneficiaries of this Agreement. Nothing in
this Agreement shall be construed to give to any Person other than the Company
and the Holders any legal or equitable right, remedy or claim under this
Agreement; but this Agreement shall be for the sole and exclusive benefit of the
Company and the Holders from time to time.

     (n) Expenses. If any action at law or in equity is necessary to enforce or
interpret the terms of this Agreement, the prevailing party shall be entitled to
reasonable attorneys' fees, costs and necessary disbursements in addition to any
other relief to which such party may be entitled.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first written above.

          registration in accordance with Rule 144 (and based on an opinion of
          counsel if the Company so requests) or (3) pursuant to an effective
          registration statement under the Securities Act, a certification to
          that effect (in substantially the form of Exhibit B hereto);

               (C) if such Registrable Security is being transferred pursuant to
          an exemption from registration in accordance with Rule 904 under the
          Securities Act (and based on an opinion of counsel if the Company so
          requests), a certification to that effect (in substantially the form
          of Exhibit B hereto); or

               (D) if such Registrable Security is being transferred in reliance
          on another exemption from the registration requirements of the

          requests), a certification to that effect (in substantially the form
          of Exhibit B hereto).

     (b) Legends.

          (i) Except for any Registrable Security sold or transferred as

     representing the Warrant Shares shall bear a legend in substantially the
     following form:

     "THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED
     IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE UNITED
     STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND THE
     SECURITY EVIDENCED HEREBY AND THE SECURITIES DELIVERED UPON EXERCISE
     THEREOF MAY NOT BE EXERCISED, OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE
     ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH
     PURCHASER OF THE SECURITY EVIDENCED HEREBY AND THE SECURITIES DELIVERED
     UPON THE EXERCISE THEREOF IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING
     ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT
     PROVIDED BY RULE 144A. THE HOLDER


                                        5
<PAGE>   6


     OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE ISSUER THAT
     SUCH SECURITY AND THE SECURITIES DELIVERED UPON EXERCISE HEREOF MAY BE
     EXERCISED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)(a) TO A
     PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL
     BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION
     MEETING THE REQUIREMENTS OF RULE 144A, (b) IN A TRANSACTION MEETING THE
     REQUIREMENTS OF RULE 144 UNDER THE SECURITIES ACT, (c) OUTSIDE THE UNITED
     STATES TO A PERSON THAT IS NOT A U.S. PERSON (AS DEFINED IN RULE 902 UNDER
     THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 904
     UNDER THE SECURITIES ACT, OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM
     THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (IN THE CASE OF (b),
     (c) or (d), UPON AN OPINION OF COUNSEL AND WRITTEN CERTIFICATION IF THE
     ISSUER, REGISTRAR OR TRANSFER AGENT FOR THE SECURITIES SO REQUESTS), (2) TO
     THE ISSUER OR (3) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN
     EACH CASE, IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE
     OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION."

          (ii) Upon any sale or transfer of a Registrable Security pursuant to
     an effective registration statement under the Securities Act, pursuant to
     Rule 144 or pursuant to an opinion of counsel reasonably satisfactory to
     the Company that no legend is required, the Holder thereof shall be
     permitted to exchange such Registrable Security for a Warrant that does not
     bear the legend set forth in clause (i) above and rescind any restriction
     on the transfer of such Registrable Security.

     (c) Obligations With Respect to Transfers and Exchanges of Warrants.

          (i) To permit registrations of transfers and exchanges, the Company
     shall execute in accordance with the provisions of Section 4 and this
     Section 5, Warrants as required pursuant to the provisions of this Section
     5. Notwithstanding anything to the contrary contained herein, the Company
     shall refuse to register any transfer of the Warrants not made in
     accordance with Regulation S, pursuant to registration under the Securities
     Act or pursuant to an available exemption from the registration
     requirements of the Securities Act; provided, however, that if a foreign
     law prevents the Company from refusing to register securities transfers,
     the Company shall implement other reasonable measures designed to prevent
     transfers of the Warrants not made in accordance with Regulation S,
     pursuant to registration under the Securities Act or pursuant to an
     available exemption from the registration requirements of the Securities
     Act.


                                       6
<PAGE>   7


          (ii) All Warrants issued upon any registration of transfer or exchange
     of Warrants shall be the valid obligations of the Company, entitled to the
     same benefits under this Warrant Agreement, as the Warrants surrendered
     upon such registration of transfer or exchange.

          (iii) Prior to due presentment for registration of transfer of any
     Warrant, the Company may deem and treat the person in whose name any
     Warrant is registered as the absolute owner of such Warrant and the Company
     shall not be affected by notice to the contrary.

          (iv) No service charge shall be made to a Holder for any registration
     of transfer or exchange.

     Section 6. Terms of Warrants; Exercise of Warrants. Subject to the terms of
this Agreement and the last paragraph of this Section 6 in particular, each
Warrant Holder shall have the right, which may be exercised at any time and from
time to time, in whole or in part, commencing on the fifteenth (15th) day after
the second anniversary of the Issue Date and ending at 4:00 p.m., Dallas, Texas
time, on the Expiration Date, to receive from the Company the number of fully
paid and nonassessable Warrant Shares which the Holder may at the time be
entitled to receive on exercise of such Warrants and payment of the Exercise
Price then in effect for such Warrant Shares. Subject to the provisions of the
following paragraph of this Section 6, each Warrant not exercised prior to 4:00
p.m., Dallas, Texas time, on the Expiration Date shall become void and all
rights thereunder and all rights in respect thereof under this Agreement shall
cease as of such time.

     A Warrant may be exercised upon surrender to the Company of the certificate
or certificates evidencing the Warrant to be exercised with the form of election
to purchase on the reverse thereof properly completed and signed, which
signature shall be guaranteed by a bank or trust company having an office or
correspondent in the United States or a broker or dealer which is a member of a
registered securities exchange or the National Association of Securities
Dealers, Inc., and upon payment to the Company of the Exercise Price as adjusted
as herein provided, for each of the Warrant Shares in respect of which such
Warrants are then exercised. Payment of the aggregate Exercise Price shall be
made in cash or by certified or official bank check, payable to the order of the
Company. In the alternative, each Holder may exercise its right to receive
Warrant Shares (i) on a net basis, such that without the exchange of any funds,
the Holder receives that number of Warrant Shares otherwise issuable upon
exercise of its Warrants less that number of Warrant Shares having a fair market
value equal to the aggregate Exercise Price that would otherwise have been paid
by the Holder for the Warrant Shares being issued, (ii) by any Holder to whom
the Company is indebted, by tendering indebtedness having an aggregate principal
amount, plus accrued but unpaid interest, if any, thereon, to the date of
exercise equal to the aggregate Exercise Price that would otherwise have been
paid by the Holder for the Warrant Shares being issued, or (iii) by a
combination of the procedures in clauses (i) and (ii). For purposes of the
foregoing sentence, "fair market value" of the Warrant Shares shall be as
determined by the Board of Directors of the Company in good faith and evidenced
by a resolution thereof. The Company shall notify the Holders in writing of any
such determination of fair market value.


                                       7

     Subject to the provisions of Section 7 hereof, upon surrender of Warrants
and payment of the Exercise Price as provided above, the Company shall promptly
transfer to the Holder of such Warrant a certificate or certificates for the
appropriate number of Warrant Shares or other securities or property (including
any money) to which the Holder is entitled, registered or otherwise placed in,
or payable to the order of, such name or names as may be directed in writing by
the Holder, and shall deliver such certificate or certificates representing the
Warrant Shares and any other securities or property (including any money) to the
Person or Persons entitled to receive the same, together with an amount in cash
in lieu of any fraction of a share as provided in Section 13. Any such
certificate or certificates representing the Warrant Shares shall be deemed to
have been issued and any Person so designated to be named therein shall be
deemed to have become a Holder of record of such Warrant Shares as of the later
of the date of the surrender of such Warrants and payment of the Exercise Price.

     Subject to the last paragraph of this Section 6, the Warrants shall be
exercisable commencing on the Issue Date, at the election of the Holders
thereof, either in full or from time to time in part and, in the event that a
certificate evidencing Warrants is exercised in respect of fewer than all of the
Warrant Shares issuable on such exercise at any time prior to the date of
expiration of the Warrants, a new certificate evidencing the remaining Warrant
or Warrants will be issued and delivered pursuant to the provisions of this
Section and of Section 3 hereof.

     All Warrant Certificates surrendered upon exercise of Warrants shall be
canceled. Such canceled Warrant Certificates shall then be disposed of in
accordance with customary procedures.

     Notwithstanding any of the provisions of this Section 6 or this Agreement,
each of the Warrants shall not be exercisable and shall become automatically
void, and all rights of the Holders thereunder and all rights of the Holders and
Nortel Networks arising under this Agreement shall terminate automatically, upon
the occurrence of any one of the events described below (all capitalized terms
not defined in the following shall have the meanings set forth in the Credit
Agreement):

     (a) The contribution to the Borrower as equity by the Company of at least
U.S. $75 million of funds (not derived from the first U.S. $111 million of
proceeds from the Company's initial public offering of its Common Stock)
following the Issue Date and at least U.S. $75 million is paid to the Lenders as
prepayment of any outstanding loan amounts under the Credit Agreement before the
second anniversary of the Issue Date;

     (b) Nortel Networks assigns at least U.S. $75 million of its Loans and
Commitments under the Credit Agreement to a Lender who is not affiliated with
Nortel Networks (excluding assignments to NTFC Capital Corporation and the
Export Development Corporation) prior to the second anniversary of the Issue
Date and such Lender does not require assignment and transfer to it of this
Warrant Agreement and the Warrants in connection with such assignment;

     (c) A combination of (x) one or more equity contributions by the Company to
the Borrower and prepayments to the Lenders of such contributions in a manner
similar to clause (a) and


                                       8
<PAGE>   9


(y) assignments of Loans and Commitments as contemplated under clause (b) above
takes place prior to the second anniversary of the Issue Date, and the total sum
of (i) the amounts of such equity contributions and prepayments to the Lenders
under clause (x) and (ii) the amounts of such assignments under clause (y)
equals at least U.S. $100 million; or

     (d) As of the second anniversary of the Issue Date, the Borrower's ratio of
Senior Debt to Total Capitalization (assuming full funding of the Loans and
Commitments under the Credit Agreement) is 0.40 to 1.0 or less and has been so
as of the end of each of the two calendar quarters immediately preceding the
second anniversary of the Issue Date.

     Section 7. Payment of Taxes. The Company will pay all documentary stamp
taxes, if any, attributable to the issuance of the Warrant Certificates or the
initial issuance of Warrant Shares upon the exercise of Warrants; provided,
however, that the Company shall not be required to pay any tax or taxes which
may be payable in respect of any transfer involved in the issue of any
certificates for Warrant Shares in a name other than that of the Holder of a
Warrant Certificate surrendered upon the exercise of a Warrant.

     Section 8. Mutilated or Missing Warrant Certificates. In case any of the
Warrant Certificates shall be mutilated, lost, stolen or destroyed, the Company
may in its discretion issue in exchange and substitution for and upon
cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, a new
Warrant Certificate of like tenor and representing an equivalent number of
Warrants, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction of such Warrant Certificate and, if
requested, indemnity reasonably satisfactory to them. Applicants for such
substitute Warrant Certificates shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company may prescribe.

     Section 9. Reservation of Warrant Shares. The Company will at all times
reserve and keep available, free from any preemptive rights, out of the
aggregate of its authorized but unissued Common Stock or its authorized and
issued Common Stock held in its treasury, for the purpose of enabling it to
satisfy any obligation to issue Warrant Shares upon exercise of Warrants, the
maximum number of shares of Common Stock which may then be deliverable upon the
exercise of all outstanding Warrants.

     The transfer agent for the Common Stock and every subsequent transfer agent
("Transfer Agent") for any shares of the Company's capital stock issuable upon
the exercise of any of the rights of purchase aforesaid will be irrevocably
authorized and directed at all times to reserve such number of authorized shares
as shall be required for such purpose. The Company will keep a copy of this
Agreement on file with the Transfer Agent for any shares of the Company's
capital stock issuable upon the exercise of the rights of purchase represented
by the Warrants. The Company will supply such Transfer Agent with duly executed
certificates for such purposes and will provide or otherwise make available any
cash which may be payable as provided in Section 13. The Company will furnish


                                       9
<PAGE>   10


such Transfer Agent a copy of all notices of adjustments and certificates
related thereto, transmitted to each Holder of the Warrants pursuant to Section
14 hereof.

     Before taking any action which would cause an adjustment pursuant to
Section 11 hereof that would reduce the Exercise Price below the then par value
(if any) of the Warrant Shares, the Company will take any corporate action which
may, in the opinion of its counsel, be necessary in order that the Company may
validly and legally issue fully paid and nonassessable Warrant Shares at the
Exercise Price as so adjusted.

     The Company covenants that all Warrant Shares which may be issued upon
exercise of Warrants in accordance with the terms of this Agreement (including
the payment of the Exercise Price) will, upon issue, be duly and validly issued,
fully paid, nonassessable, and free of preemptive rights and Liens.

     Section 10. Obtaining Stock Exchange Listings. The Company will from time
to time take all action which may be necessary so that the Warrant Shares,
immediately upon their issuance upon the exercise of Warrants, will be listed on
the principal securities exchanges and markets (including, without limitation,
the Nasdaq National or SmallCap Markets) within the United States of America, if
any, on which other shares of Common Stock are then listed. Upon the listing of
such Warrant Shares, the Company shall notify the Holders in writing. The
Company will obtain and keep all required permits and records in connection with
such listing.

     Section 11. Adjustment of Exercise Price and Number of Warrant Shares
Issuable. The number and kind of shares purchasable upon the exercise of
Warrants and the Exercise Price shall be subject to adjustment from time to time
(as set forth in the notices required by Section 14 hereof) as follows:

     (a) Stock Splits, Combinations, etc. In case the Company shall hereafter
(A) pay a dividend or make a distribution on its Common Stock in shares of its
capital stock (whether shares of Common Stock or of capital stock of any other
class), (B) subdivide its outstanding shares of Common Stock, (C) combine its
outstanding shares of Common Stock into a smaller number of shares, or (D) issue
by reclassification of its shares of Common Stock any shares of capital stock of
the Company, the Exercise Price in effect and the number of Warrant Shares
issuable upon exercise of each Warrant immediately prior to such action shall be
adjusted so that the Holder of any Warrant thereafter exercised shall be
entitled to receive the number of shares of capital stock of the Company which
such Holder would have owned immediately following such action had such Warrant
been exercised immediately prior thereto. Any adjustment made pursuant to this
paragraph shall become effective immediately after the record date in the case
of a dividend and shall become effective immediately after the effective date in
the case of a subdivision, combination or reclassification. If, as a result of
an adjustment made pursuant to this paragraph, the Holder of any Warrant
thereafter exercised shall become entitled to receive shares of two or more
classes of capital stock of the Company, the Board of Directors of the Company
shall in good faith determine the allocation of the adjusted Exercise Price
between or among shares of such classes of capital stock.


                                       10

     (b) Reclassification, Combinations, Mergers, etc. In case of any
reclassification or change of outstanding shares of Common Stock issuable upon
exercise of the Warrants (other than as set forth in paragraph (a) above and
other than a change in par value, or from par value to no par value, or from no
par value to par value or as a result of a subdivision or combination), or in
case of any consolidation or merger of the Company with or into another
corporation (other than a merger in which the Company is the continuing
corporation and which does not result in any reclassification or change of the
then outstanding shares of Common Stock or other capital stock issuable upon
exercise of the Warrants) or in case of any sale or conveyance to another
corporation of all or substantially all of the assets of the Company, then, as a
condition of such reclassification, change, consolidation, merger, sale or
conveyance, the Company or such a successor or purchasing corporation, as the
case may be, shall forthwith make lawful and adequate provision whereby the
Holder of each Warrant then outstanding shall have the right thereafter to
receive on exercise of such Warrant the kind and amount of shares of stock and
other securities and property receivable upon such reclassification, change,
consolidation, merger, sale or conveyance by a Holder of the number of shares of
Common Stock issuable upon exercise of such Warrant immediately prior to such
reclassification, change, consolidation, merger, sale or conveyance and enter
into a supplemental warrant agreement so providing. Such provisions shall
include provision for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 11. If the issuer of
securities deliverable upon exercise of Warrants under the supplemental warrant
agreement is an affiliate of the formed, surviving or transferee corporation,
that issuer shall join in the supplemental warrant agreement. The above
provisions of this paragraph (b) shall similarly apply to successive
reclassifications and changes of shares of Common Stock and to successive
consolidations, mergers, sales or conveyances.

     (c) Issuance of Additional Shares of Common Stock. In the event the Company
shall, at any time or from time to time after the date hereof, issue, sell,
distribute or otherwise grant in any manner (including by assumption) any
additional shares of Common Stock without consideration or for a price per share
less than the current market price per share of Common Stock on the date of the
issuance, sale, distribution or granting of such additional shares, then,
effective upon such issuance or sale, (I) the Exercise Price shall be reduced to
the price (calculated to the nearest 1/1,000 of one cent) determined by
multiplying the Exercise Price in effect immediately prior to such issuance or
sale by a fraction, the numerator of which shall be the sum of (i) the number of
shares of Common Stock outstanding (exclusive of any treasury shares)
immediately prior to such issuance or sale multiplied by the current market
price per share of Common Stock on the date of such issuance or sale plus (ii)
the consideration, if any, received by the Company in respect of such issuance
or sale, and the denominator of which shall be the product of (A) the total
number of shares of Common Stock outstanding (exclusive of any treasury shares)
immediately after such issuance or sale multiplied by (B) the current market
price per share of Common Stock on the record date for such issuance or sale and
(II) the number of shares of Common Stock purchasable upon the exercise of each
Warrant shall be increased to a number determined by multiplying the number of
shares of Common Stock so purchasable immediately prior to the record date for
such issuance or sale by a fraction, the numerator of which shall be the
Exercise Price in effect immediately prior to the adjustment required by clause


                                       11
<PAGE>   12


(I) of this sentence and the denominator of which shall be the Exercise Price in
effect immediately after such adjustment.

     (d) Issuance of Options or Convertible Securities. In the event the Company
shall, at any time or from time to time after the date hereof, issue, sell,
distribute or otherwise grant in any manner (including by assumption) any rights
to subscribe for or to purchase, or any warrants or options for the purchase of,
Common Stock or any stock or securities convertible into or exchangeable for
Common Stock (any such rights, warrants or options being herein called "Options"
and any such convertible or exchangeable stock or securities being herein called
"Convertible Securities") or any Convertible Securities (other than upon
exercise of any Option), whether or not such Options or the rights to convert or
exchange such Convertible Securities are immediately exercisable, and if the
price per share at which Common Stock is issuable upon the exercise of such
Options or upon the conversion or exchange of such Convertible Securities
(determined by dividing (i) the aggregate amount, if any, received or receivable
by the Company as consideration for the issuance, sale, distribution or granting
of such Options or any such Convertible Security, plus the minimum aggregate
amount of additional consideration, if any, payable to the Company upon the
exercise of all such Options or upon conversion or exchange of all such
Convertible Securities, plus, in the case of Options to acquire Convertible
Securities, the minimum aggregate amount of additional consideration, if any,
payable upon the conversion or exchange of all such Convertible Securities, by
(ii) the total maximum number of shares of Common Stock issuable upon the
exercise of all such Options or upon the conversion or exchange of all such
Convertible Securities or upon the conversion or exchange of all Convertible
Securities issuable upon the exercise of all such Options) shall be less than
the current market price per share of Common Stock on the date for the issuance,
sale, distribution or granting of such Options or Convertible Securities (any
such event being herein called a "Distribution"), then, effective upon such
Distribution, (I) the Exercise Price shall be reduced to the price (calculated
to the nearest 1/1,000 of one cent) determined by multiplying the Exercise Price
in effect immediately prior to such Distribution by a fraction, the numerator of
which shall be the sum of (i) the number of shares of Common Stock outstanding
(exclusive of any treasury shares) immediately prior to such Distribution
multiplied by the current market price per share of Common Stock on the date of
such Distribution plus (ii) the consideration, if any, received by the Company
in respect of such Distribution, and the denominator of which shall be the
product of (A) the total number of shares of Common Stock outstanding (exclusive
of any treasury shares) immediately after such Distribution multiplied by (B)
the current market price per share of Common Stock on the record date for such
Distribution and (II) the number of shares of Common Stock purchasable upon the
exercise of each Warrant shall be increased to a number determined by
multiplying the number of shares of Common Stock so purchasable immediately
prior to the record date for such Distribution by a fraction, the numerator of
which shall be the Exercise Price in effect immediately prior to the adjustment
required by clause (I) of this sentence and the denominator of which shall be
the Exercise Price in effect immediately after such adjustment. For purposes of
the foregoing, the total maximum number of shares of Common Stock issuable upon
exercise of all such Options or upon conversion or exchange of all such
Convertible Securities or upon the conversion or exchange of the total maximum
amount of the Convertible Securities issuable upon the exercise of all such
Options shall be deemed to have been issued as of the date of such Distribution
and thereafter shall be deemed to


                                       12
<PAGE>   13


be outstanding and the Company shall be deemed to have received as consideration
therefor such price per share, determined as provided above. Except as provided
in paragraphs (j) and (k) below, no additional adjustment of the Exercise Price
shall be made upon the actual exercise of such Options or upon conversion or
exchange of the Convertible Securities or upon the conversion or exchange of the
Convertible Securities issuable upon the exercise of such Options.

     (e) Dividends and Distributions. In the event the Company shall, at any
time or from time to time after the date hereof, distribute to all the holders
of Common Stock any dividend or other distribution of cash, evidences of its
indebtedness, other securities or other properties or assets (in each case other
than (i) dividends payable in Common Stock, Options or Convertible Securities
and (ii) any cash dividend that, when added to all other cash dividends paid
with respect to Common Stock in the one year prior to the declaration date of
such dividend (excluding any such other dividend included in a previous
adjustment of the Exercise Price pursuant to this paragraph (e) and excluding
any cash dividends or other cash distributions from current or retained
earnings), does not exceed 5% of the current market price per share of Common
Stock on such declaration date), or any options, warrants or other rights to
subscribe for or purchase any of the foregoing, then (A) the Exercise Price
shall be decreased to a price determined by multiplying the Exercise Price then
in effect by a fraction, the numerator of which shall be the current market
price per share of Common Stock on the record date for such distribution less
the sum of (X) the cash portion, if any, of such distribution per share of
Common Stock outstanding (exclusive of any treasury shares) on the record date
for such distribution plus (Y) the then fair market value (as determined in good
faith by the Board of Directors of the Company) per share of Common Stock
outstanding (exclusive of any treasury shares) on the record date for such
distribution of that portion, if any, of such distribution consisting of
evidences of indebtedness, other securities, properties, assets, options,
warrants or subscription or purchase rights, and the denominator of which shall
be such current market price per share of Common Stock and (B) the number of
shares of Common Stock purchasable upon the exercise of each Warrant shall be
increased to a number determined by multiplying the number of shares of Common
Stock so purchasable immediately prior to the record date for such distribution
by a fraction, the numerator of which shall be the Exercise Price in effect
immediately prior to the adjustment required by clause (A) of this sentence and
the denominator of which shall be the Exercise Price in effect immediately after
such adjustment. The adjustments required by this paragraph (e) shall be made
whenever any such distribution occurs retroactive to the record date for the
determination of stockholders entitled to receive such distribution.

     (f) Current Market Price. For the purpose of any computation of current
market price under this Section 11 and Section 13, the current market price per
share of Common Stock at any date shall be (x) for purposes of Section 13, the
closing price on the business day immediately prior to the exercise of the
applicable Warrant pursuant to Section 6 and (y) in all other cases, the average
of the daily closing prices for the shorter of (i) the 20 consecutive trading
days ending on the last full trading day on the exchange or market specified in
the second succeeding sentence prior to the Time of Determination (as defined
below) and (ii) the period commencing on the date next succeeding the first
public announcement of the issuance, sale, distribution or granting in question
through such last full trading day prior to the Time of Determination. The term
"Time of Determination" as used herein


                                       13
<PAGE>   14


shall be the time and date of the earlier to occur of (A) the date as of which
the current market price is to be computed and (B) the last full trading day on
such exchange or market before the commencement of "ex-dividend" trading in the
Common Stock relating to the event giving rise to the adjustment required by
paragraph (a), (b), (c), (d) or (e) above. The closing price for any day shall
be the last reported sale price regular way or, in case no such reported sale
takes place on such day, the average of the closing bid and asked prices regular
way for such day, in each case (1) on the principal national securities exchange
on which the shares of Common Stock are listed or to which such shares are
admitted to trading or (2) if the Common Stock is not listed or admitted to
trading on a national securities exchange, in the over-the-counter market as
reported by Nasdaq National or SmallCap Markets or any comparable system or (3)
if the Common Stock is not listed on Nasdaq National or SmallCap Markets or a
comparable system, as furnished by two members of the NASD selected from time to
time in good faith by the Board of Directors of the Company for that purpose. In
the absence of all of the foregoing, or if for any other reason the current
market price per share cannot be determined pursuant to the foregoing provisions
of this paragraph (f), the current market price per share shall be the fair
market value thereof as determined in good faith by the Board of Directors of
the Company and evidenced by a resolution of such Board, subject to the
following dispute resolution right of the Holders of the Warrants. In the event
that Holders of a majority of the Warrants dispute the determination of the
Board of Directors, such Holders shall notify the Company and the current market
price shall be determined in a reasonably prompt manner as follows:

          (1) The Company and Holders of a majority of the Warrants shall each
     appoint an independent, experienced appraiser who is a member of a
     recognized professional association of business appraisers. The two
     appraisers shall determine the value of shares of Common Stock at the
     relevant date, assuming a sale between a willing buyer and a willing
     seller, both of whom have full knowledge of the financial and other affairs
     of the Company, and neither of whom is under any compulsion to sell or to
     buy.

          (2) If the higher of the two appraisals is not more than 20% more than
     the lower of the appraisals, the current market price per share shall be
     the average of the two appraisals. If the higher of the two appraisals is
     20% or more than the lower of the two appraisals, then a third appraiser
     shall be appointed by the two appraisers, and if they cannot agree on a
     third appraiser, the American Arbitration Association shall appoint the
     third appraiser. The third appraiser, regardless of who appoints him or
     her, shall have the same qualifications as the first two appraisers.

          (3) The current market price per share after the appointment of the
     third appraiser shall be the average of the two appraisals that are closest
     in value to each other.

          (4) The fees and expenses of the appraisers shall be paid one-half by
     the Company and one-half by the Holders.

     (g) Certain Distributions. If the Company shall pay a dividend or make any
other distribution payable in Options or Convertible Securities, then, for
purposes of paragraph (d) above,


                                       14
<PAGE>   15


such Options or Convertible Securities shall be deemed to have been issued or
sold without consideration.

     (h) Consideration Received. If any shares of Common Stock, Options or
Convertible Securities shall be issued, sold or distributed for a consideration
other than cash, the amount of the consideration other than cash received by the
Company in respect thereof shall be deemed to be the then fair market value of
such consideration (as determined in good faith by the Board of Directors of the
Company and evidenced by a Board resolution). If any Options shall be issued in
connection with the issuance and sale of other securities of the Company,
together comprising one integral transaction in which no specific consideration
is allocated to such Options by the parties thereto, such Options shall be
deemed to have been issued without consideration; provided, however, that if
such Options have an exercise price equal to or greater than the current market
price of the Common Stock on the date of issuance of such Options, then such
Options shall be deemed to have been issued for consideration equal to such
exercise price.

     (i) Deferral of Certain Adjustments. No adjustment to the Exercise Price
(including the related adjustment to the number of shares of Common Stock
purchasable upon the exercise of each Warrant) shall be required hereunder
unless such adjustment, together with other adjustments carried forward as
provided below, would result in an increase or decrease of at least one percent
of the Exercise Price; provided that any adjustments which by reason of this
paragraph (i) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. No adjustment need be made for a
change in the par value of the Common Stock. All calculations under this Section
shall be made to the nearest 1/1,000 of one cent or to the nearest 1/1000 of a
share, as the case may be.

     (j) Changes in Options and Convertible Securities. If the exercise price
provided for in any Options referred to in paragraph (d) above, the additional
consideration, if any, payable upon the conversion or exchange of any
Convertible Securities referred to in paragraph (d) or (e) above, or the rate at
which any Convertible Securities referred to in paragraph (d) or (e) above are
convertible into or exchangeable for Common Stock shall change at any time
(other than under or by reason of provisions designed to protect against
dilution upon an event which results in a related adjustment pursuant to this
Section 11), the Exercise Price then in effect and the number of shares of
Common Stock purchasable upon the exercise of each Warrant shall forthwith be
readjusted (effective only with respect to any exercise of any Warrant after
such readjustment) to the Exercise Price and number of shares of Common Stock so
purchasable that would then be in effect had the adjustment made upon the
issuance, sale, distribution or granting of such Options or Convertible
Securities been made based upon such changed purchase price, additional
consideration or conversion rate, as the case may be, but only with respect to
such Options and Convertible Securities as then remain outstanding.

     (k) Expiration of Options and Convertible Securities. If, at any time after
any adjustment to the number of shares of Common Stock purchasable upon the
exercise of each Warrant shall have been made pursuant to paragraph (d), (e) or
(j) above or this paragraph (k), any Options or Convertible Securities shall
have expired unexercised, the number of such shares so purchasable shall,


                                       15
<PAGE>   16


upon such expiration, be readjusted and shall thereafter be such as they would
have been had they been originally adjusted (or had the original adjustment not
been required, as the case may be) as if (i) the only shares of Common Stock
deemed to have been issued in connection with such Options or Convertible
Securities were the shares of Common Stock, if any, actually issued or sold upon
the exercise of such Options or Convertible Securities and (ii) such shares of
Common Stock, if any, were issued or sold for the consideration actually
received by the Company upon such exercise plus the aggregate consideration, if
any, actually received by the Company for the issuance, sale, distribution or
granting of all such Options or Convertible Securities, whether or not
exercised; provided that no such readjustment shall have the effect of
decreasing the number of such shares so purchasable by an amount (calculated by
adjusting such decrease to account for all other adjustments made pursuant to
this Section 11 following the date of the original adjustment referred to above)
in excess of the amount of the adjustment initially made in respect of the
issuance, sale, distribution or granting of such Options or Convertible
Securities.

     (l) Other Adjustments. In the event that at any time, as a result of an
adjustment made pursuant to this Section 11, the Holders shall become entitled
to receive any securities of the Company other than shares of Common Stock,
thereafter the number of such other securities so receivable upon exercise of
the Warrants and the Exercise Price applicable to such exercise shall be subject
to adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the shares of Common Stock
contained in this Section 11.

     (m) Employee Plans. No adjustment in the Exercise Price or the number and
kind of shares purchaseable upon exercise of the Warrants shall be made under
the provisions of Section 11 for shares of Common Stock and Common Equity
Securities issued or issuable as compensation to employees of the Company or its
subsidiaries but only to the extent that the total aggregate number of issued
and issuable shares of Common Stock in connection therewith does not exceed
_______________ shares [15% OF THE FULLY DILUTED OUTSTANDING SHARES OF COMMON
STOCK ON ISSUE DATE].

     Section 12. Statement on Warrants. Irrespective of any adjustment in the
number or kind of shares issuable upon the exercise of the Warrants or the
Exercise Price, Warrants theretofore or thereafter issued may continue to
express the same number and kind of shares as are stated in the Warrants
initially issuable pursuant to this Agreement.

     Section 13. Fractional Interest. The Company shall not be required to issue
fractional shares of Common Stock on the exercise of Warrants. If more than one
Warrant shall be presented for exercise in full at the same time by the same
Holder, the number of full shares of Common Stock which shall be issuable upon
such exercise shall be computed on the basis of the aggregate number of shares
of Common Stock acquirable on exercise of the Warrants so presented. If any
fraction of a share of Common Stock would, except for the provisions of this
Section 13, be issuable on the exercise of any Warrant (or specified portion
thereof), the Company shall direct the Transfer Agent to pay an amount in cash
calculated by it equal to (i) the then current market price per share multiplied
by such fraction computed to the nearest whole cent, less (ii) an amount equal
to the


                                       16
<PAGE>   17


Exercise Price multiplied by such fraction computed to the nearest whole cent.
The Holders, by their acceptance of the Warrant Certificates, expressly waive
any and all rights to receive any fraction of a share of Common Stock or a stock
certificate representing a fraction of a share of Common Stock.

     Section 14. Notices to Warrant Holders. Upon any adjustment of the Exercise
Price pursuant to Section 11, the Company shall promptly thereafter cause to be
given to each of the registered Holders by first-class mail, postage prepaid, a
certificate executed by the Chief Financial Officer of the Company setting forth
the Exercise Price after such adjustment and setting forth in reasonable detail
the method of calculation and the facts upon which such calculations are based
and setting forth the number of Warrant Shares (or portion thereof) issuable
after such adjustment in the Exercise Price, upon exercise of a Warrant and
payment of the adjusted Exercise Price, which certificate shall be conclusive
evidence, absent manifest error, of the correctness of the matters set forth
therein.

     In case:
          (a) the Company shall authorize the issuance to all holders of shares
     of Common Stock of rights, options or warrants to subscribe for or purchase
     shares of Common Stock or of any other subscription rights or warrants; or

          (b) the Company shall authorize the distribution to all holders of
     shares of Common Stock of evidences of its indebtedness or assets (other
     than cash dividends or cash distributions payable out of consolidated
     earnings or earned surplus or dividends payable in shares of Common Stock
     or distributions referred to in Section 11 hereof); or

          (c) of any consolidation or merger to which the Company is a party for
     which approval of any shareholders of the Company is required and following
     which the shareholders of the Company before such consolidation or merger
     no longer hold at least 75% of the outstanding capital stock of the Company
     following the merger or consolidation, or of the conveyance or transfer of
     all or substantially all of the properties and assets of the Company, or of
     any reclassification or change of Common Stock issuable upon exercise of
     the Warrants (other than a change in par value, or from par value to no par
     value, or from no par value to par value, or as a result of a subdivision
     or combination), or a tender offer or exchange offer for shares of Common
     Stock, or other transaction that would result in a change in control; or

          (d) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company; or

          (e) the Company proposes to take any other action that would require
     an adjustment of the Exercise Price or the number of Warrant Shares
     pursuant to Section 11; then the Company shall cause to be given to each of
     the registered Holders of the Warrants at such Holder's address appearing
     on the Warrant register, at least 20 days (or 10 days in any case specified
     in clauses (a) or (b) above) prior to the applicable record date
     hereinafter


                                       17
<PAGE>   18


     specified, or promptly in the case of events for which there is no record
     date, by first-class mail, postage prepaid, a written notice stating (i)
     the date as of which the holders of record of shares of Common Stock to be
     entitled to receive any such rights, options, warrants or distribution are
     to be determined, or (ii) the initial expiration date set forth in any
     tender offer or exchange offer for shares of Common Stock, or (iii) the
     date on which any such consolidation, merger, conveyance, transfer,
     dissolution, liquidation or winding up or change of control is expected to
     become effective or consummated, and the date as of which it is expected
     that holders of record of shares of Common Stock shall be entitled to
     exchange such shares for securities or other property, if any, deliverable
     upon such reclassification, consolidation, merger, conveyance, transfer,
     dissolution, liquidation or winding up or change of control. The failure to
     give the notice required by this Section 14 or any defect therein shall not
     affect the legality or validity of any distribution, right, option,
     warrant, consolidation, merger, conveyance, transfer, dissolution,
     liquidation or winding up, or change of control or the vote upon any
     action. Nothing contained in this Agreement or in any of the Warrant
     Certificates shall be construed as conferring upon the Holders thereof the
     right to vote or to consent or to receive notice as shareholders in respect
     of the meetings of shareholders or the election of Directors of the Company
     or any other matter, or any rights whatsoever as shareholders of the
     Company.

     Section 15. Registration. The Company acknowledges that Holders of Warrants
shall have the registration rights set forth in the Registration Rights
Agreement.

     Section 16. Reports. For each fiscal quarter and each fiscal year of the
Company, the Company will transmit by mail to all Warrant Holders, as their
names and addresses appear in the register, without cost to such Warrant
Holders, unaudited quarterly and audited annual financial statements of the
Company prepared in accordance with GAAP. Beginning with the initial public
offering of the Company and thereafter, whether or not the Company is subject to
Section 13(a) or 15(d) of the Exchange Act, or any successor provision thereto,
the Company shall prepare the annual and quarterly reports and other
information, and documents ("SEC Reports") as the Commission shall prescribe
pursuant to such Section 13(a) or 15(d) and which the Company is or would be (if
they were so subject) required to file with the Commission pursuant to such
Section 13(a) or 15(d) or any successor provision thereto (on or prior to the
respective dates (the "Required Filing Dates") by which the Company is or would
(if they were so subject) be required so to file such SEC Reports) and shall,
within 15 days of the Required Filing Date transmit by mail to all Warrant
Holders, as their names and addresses appear in the register, without cost to
such Warrant Holders, copies of such annual and quarterly reports.

     Section 17. Rule 144A. The Company hereby agrees with each Holder, for so
long as any Registrable Securities remain outstanding and the Company is not
subject to Section 13(a) or 15(d) of the Exchange Act, to make available, upon
request of any Holder of Registrable Securities, to any Holder or beneficial
owner of Registrable Securities in connection with any sale thereof and any
prospective purchaser of such Registrable Securities designated by such Holder
or beneficial owner,


                                       18
<PAGE>   19


the information required by Rule 144A(d)(4) under the Securities Act in order to
permit resales of such Registrable Securities pursuant to Rule 144A.

     Section 18. Notices to Holders and Company. All notices and other

deemed "in writing" for purposes of this Agreement) and telecopies, telegraphed,
cabled, mailed or delivered to the intended recipient at the address for such

                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         This Amended and Restated Employment Agreement (this "Agreement") is
entered into this date by and between ALAMOSA PCS, LLC, a Texas Limited
Liability Company, having its principal executive office located at 4403
Brownfield Highway, Lubbock, Texas 79407 (the "Company"), and JERRY BRANTLEY, an

                                   WITNESSETH:

         WHEREAS, the parties entered into an employment agreement as of October
1, 1998; and

         WHEREAS, the parties desire to amend and restate said employment
agreement to set forth and confirm their respective rights and obligations with
respect to the Employee's continued employment by the Company.

         NOW, THEREFORE, in consideration of the mutual covenants herein

         1. EMPLOYMENT; TERM; DUTIES. The Company hereby continues to employ the
Employee as President and Chief Operating Officer ("COO") pursuant to this
Agreement, for the period from October 1, 1999, (the "Commencement Date") until

of Sections 7 through 10 hereof, the Company acknowledges and consents to the
continuation of these ownerships and relationships, provided they do not
interfere with the Employee's duties under this Agreement. Notwithstanding
anything to the contrary in this Agreement, nothing in this Agreement shall be
deemed to impose any obligation on the Company or any of its subsidiaries to
continue to employ the Employee, or on the Employee to remain in the employ of

                  (a) BASE SALARY. The Company will pay the Employee a base
                  salary at the annual rate of $175,000.00, payable periodically
                  but no less often than semi-monthly, in substantially equal
                  amounts, in accordance with the Company's payroll practices
                  from time to time in effect. The Company will review the
                  Employee's base salary at least once each year and may, in its
                  discretion, increase the Employee's base salary.

                  (b) BONUS. In addition to the Employee's base salary, the
                  Employee shall be eligible to receive a bonus (a "Quarterly
                  Bonus") for each calendar quarter in an amount, if any,
                  determined as follows: In each calendar quarter Employee's
                  Quarterly Bonus shall be equal to the sum of (1) plus (2) as
                  follows:

                           (1) $15,000.00 multiplied by the percentage set forth
                           opposite each Expected Milestone set forth in the
                           attached EXHIBIT "A", incorporated herein by
                           reference, which is achieved for that calender
                           quarter.

                           (2) $15,000.00 multiplied by the percentage set forth
                           opposite each Exceptional Milestone set forth in
                           EXHIBIT "A" which is achieved for that calendar
                           quarter.

                  If any particular Expected Milestone or Exceptional Milestone
                  is not achieved for any calendar quarter, that percentage
                  share of the dollar amount specified in (1) or (2) above, as
                  the case may be, shall not be payable as part of the Quarterly
                  Bonus. The Expected Milestones, Exceptional Milestones and
                  percentages set forth on EXHIBIT "A" may be changed by the
                  Company at any time and from time to time, but shall be
                  reasonable by wireless industry standards. Any such change
                  shall not apply earlier than the calendar quarter following
                  the calendar quarter in which such change is made by the
                  Company and communicated to the Employee.

                  Any Quarterly Bonus owing to the Employee shall be paid within
                  forty-five (45) days following the end of the applicable
                  calendar quarter.

                  (c) UNIT OPTIONS. Any options granted to the Employee under
                  his prior employment agreement shall be canceled, and the
                  Employee shall have no further rights with respect to those
                  options. It is the Company's intention to assign its rights
                  and obligations under this Agreement to Alamosa PCS Holdings,
                  Inc. ("Holdings") and become a wholly-owned subsidiary of
                  Holdings. If, on June 30, 2000, the Company or its successor

                  (iii) any act or omission by Employee which constitutes a
                  uncured default or breach of that certain Sprint PCS
                  Management Agreement dated July 17, 1998 and as it may be
                  amended from time to time or any other similar Sprint
                  Management Agreement to which the Company or any of its
                  affiliates or subsidiaries may be a party ("the Sprint
                  Agreement"); or (iv) any other intentional misconduct by the
                  Employee adversely affecting the business or affairs of the
                  Company in a material manner. The term "intentional misconduct
                  by the Employee adversely affecting the business or affairs of
                  the Company" shall mean such misconduct that is detrimental to
                  the business or the reputation of the Company as it is
                  perceived both by the general public and the
                  telecommunications industry.

                  (c) The term "cause" in the event of termination of the
                  Employee's employment by the Employee means the change in job
                  responsibilities of the Employee resulting in the demotion,
                  removal or failure to elect Employee to the position of
                  President and COO or the job responsibilities of that
                  position, which demotion, removal or failure to elect is
                  caused by something other than cause for termination of the
                  Employee's employment by the Company under Section 5(b) hereof
                  and other than the non-performance of the Employee as defined
                  under Section 5(d) hereof.

                  (d) The term "non-performance by the Employee" in the event of
                  termination of the Employee's employment by the Company means
                  the determination by a super-majority (greater than 75%) of
                  the members of the Board of Managers of the Company, in their
                  sole and absolute discretion, that the Employee is not
                  performing his duties under this Agreement after the Board of
                  Managers of the Company has delivered to the Employee written
                  notice which specifically identifies the manner in which the
                  Board believes he is not performing his duties and which is
                  not or cannot be cured within 15 days after such written
                  notice is delivered to the Employee.

         6. CONSEQUENCES OF TERMINATION.

                  (a) CONSEQUENCES OF TERMINATION ON EMPLOYEE'S DEATH OR
                  DISABILITY. If the Employee's employment is terminated prior
                  to September 30, 2003, because of the Employee's death or
                  disability, (i) subject to Section 6(h) hereof, this Agreement
                  terminates immediately; (ii) Employee or his legal
                  representative or estate, as the case may be, shall be
                  eligible to exercise any options granted and vested pursuant
                  to Section 2(c) hereof at the time of such death or
                  disability, plus, if such death or disability does not occur
                  on September 30 of a given year, a fractional portion of those
                  options which would have vested and become exercisable
                  pursuant to Section 2(c) hereof on the September 30
                  immediately following such death or disability based on a
                  fraction whose numerator is the number of months (including
                  the month in which the date of death or disability occurs)
                  since the previous September 30 and whose denominator is
                  twelve (12), in accordance with the provisions of Section 2(c)
                  hereof and the option agreement referred to therein, and any
                  other options granted to the Employee shall be forfeited;
                  (iii) the Company will pay the Employee, or his legal
                  representative or estate, as the case may be, in full
                  satisfaction of all of its compensation (base salary and
                  bonus) obligations under this Agreement, an amount equal to
                  the sum of any base salary due to the Employee through the
                  last day of employment, plus any accrued bonus to which the
                  Employee may have been entitled on the last day of employment,
                  but had not yet been received; and (iv) the Employee's
                  benefits and rights under any Benefit Plan shall be paid,
                  retained or forfeited in accordance with the terms of such
                  plan; provided, however, that Employer shall have no
                  obligation to make any payments toward these benefits for
                  Employee from and after termination.

                  (b) CONSEQUENCES OF TERMINATION BY THE COMPANY FOR ANY REASON
                  OTHER THAN FOR CAUSE OR FOR NON-PERFORMANCE OF EMPLOYEE.

                           (1) If the Employee's employment is terminated by the
                           Company prior to September 30, 2003, for any reason
                           other than for cause or non-performance of Employee,
                           (i) subject to Section 6(h) hereof, this Agreement
                           terminates immediately; (ii) Employee or his legal
                           representative or estate, as the case may be, shall
                           be eligible to exercise any options granted but not
                           exercised pursuant to Section 2(c) hereof, all of
                           which options shall be deemed vested as of the date
                           of the Employee's termination of employment
                           regardless of whether or not they are in fact
                           otherwise vested pursuant to Section 2(c) hereof on
                           said date, in accordance with the provisions of
                           Section 2(c) hereof and the option agreement referred
                           to therein; (iii) the Company will pay the Employee,
                           in full satisfaction of all of its compensation (base
                           salary and bonus) obligations under this Agreement,
                           an amount equal to the sum of any base salary due to
                           the Employee through the last day of employment, plus
                           any accrued bonus to which the Employee may have been
                           entitled on the last day of employment, but had not
                           yet been received; (iv) the Company will pay the
                           Employee, within sixty (60) days of such termination,
                           a lump sum severance payment equal to one (1) year's
                           base salary as in effect at the date of employment
                           termination; and (v) the Employee's benefits and
                           rights under any Benefit Plan, other than any basic
                           health and medical benefit plan, shall be paid,
                           retained or forfeited in accordance with the terms of
                           such plan; provided, however, that Employer shall
                           have no obligation to make any payments toward these
                           benefits for Employee from and after termination.

                           (2) Any payment pursuant to clause (b)(1)(iv) above
                           (the "Termination Payment"):

                                    a. will be subject to offset for any
                                    advances, amounts receivable, and loans,
                                    including accrued interest, outstanding on
                                    the date of the employment termination; and

                                    b. will not be subject to offset on account
                                    of any remuneration paid or payable to the
                                    Employee for any subsequent employment the
                                    Employee may obtain, whether during or after
                                    the period during which the Termination



EMPLOYMENT AGREEMENT              Page 7 of 22

                                    Payment is made, and the Employee shall have
                                    no obligation whatever to seek any
                                    subsequent employment.

                  (c) CONSEQUENCES OF TERMINATION FOR CAUSE BY THE COMPANY. If
                  the Employee's employment is terminated by the Company prior
                  to September 30, 2003, for cause, (i) subject to Section 6(h)
                  hereof, this Agreement terminates immediately; (ii) Employee
                  shall not be eligible to exercise and shall forfeit any
                  options granted (whether or not vested) pursuant to Section
                  2(c) hereof at the time of such employment termination that
                  have not already been exercised by the Employee at the time of
                  such employment termination; (iii) the Company will pay the
                  Employee, in full satisfaction of all of its compensation
                  (base salary and bonus) obligations under this Agreement, an
                  amount equal to the sum of any base salary due to the Employee
                  through the last day of employment, plus any accrued bonus to
                  which the Employee may have been entitled on the last day of
                  employment, but had not yet been received; and(iv) the
                  Employee's benefits and rights under any Benefit Plan shall be
                  paid, retained or forfeited in accordance with the terms of
                  such plan; provided, however, that Employer shall have no
                  obligation to make any payments toward these benefits for
                  Employee from and after termination.

                  (d) CONSEQUENCES OF TERMINATION BY THE EMPLOYEE FOR ANY REASON
                  OTHER THAN FOR CAUSE OR EMPLOYEE'S DEATH OR DISABILITY. If,
                  upon forty-five (45) days' prior written notice to the Company
                  by the Employee, the Employee's employment is terminated by
                  the Employee prior to September 30, 2003, for any reason other
                  than for cause or Employee's death or disability, (i) subject
                  to Section 6(h) hereof, this Agreement terminates immediately;
                  (ii) Employee or his legal representative or estate, as the
                  case may be, shall be eligible to exercise any options granted
                  and vested, but not exercised pursuant to Section 2(c) hereof

                  Employee, in full satisfaction of all of its compensation
                  (base salary and bonus) obligations under this Agreement, an
                  amount equal to the sum of any base salary due to the Employee
                  through the last day of employment, plus any accrued bonus to

                  obligation to make any payments toward these benefits for
                  Employee from and after termination.

                           notice to the Company by the Employee, the Employee's
                           employment is terminated by the Employee prior to
                           September 30, 2003, for cause (i) subject to Section

                           less; and (v) the Employee's benefits and rights
                           under any Benefit Plan, other than any basic health

                                    the period during which the Termination
                                    Payment is made, and the Employee shall have

                  non-performance by the Employee (i) subject to Section 6(h)
                  hereof, this Agreement terminates immediately; (ii) Employee
                  or his legal representative or estate, as the case may be,
                  shall be eligible to exercise any options granted and vested
                  but not exercised pursuant to Section 2(c) hereof at the time
                  of such employment termination, in accordance with the
                  provisions of Section 2(c) hereof and the option agreement
                  referred to therein, and any other options granted to the
                  Employee shall be forfeited; (iii) the Company will pay the
                  Employee, in full satisfaction of all of its compensation

                           other than for cause (as defined in Section 5(b)

                           but not exercised pursuant to Section 2(c) hereof all
                           of which options shall be deemed vested as of the
                           date of the Employee's termination of employment
                           regardless of whether or not they are in fact
                           otherwise vested pursuant to Section 2(c) hereof on
                           said date, in accordance with the provisions of
                           Section 2(c) hereof and the option agreement referred
                           to therein; (iii) the Company will pay the Employee,
                           in full satisfaction of all of its compensation (base

                           an amount equal to the sum of any base salary due to

                           yet been received; (iv) the Company will pay the
                           Employee, within sixty (60) days of such termination,

                           balance of the base salary which would have been
                           payable to Employee through September 30, 2003; and
                           (v) the Employee's benefits and rights under any

                           however, that Employer shall have no obligation to
                           make any payments toward these benefits for Employee
                           from and after termination.

                           (2) The term "Change of Control" shall have the same

                           (3) Any payment pursuant to clause (g)(1)(iv) above
                           (the "Termination Payment"):

                                    a. will be subject to offset for any
                                    advances, amounts receivable, and loans,
                                    including accrued interest outstanding on
                                    the date of the employment termination; and

ALAMOSA PCS LLC and Jerry Brantley
<PAGE>   12

                                    b. will not be subject to offset on account
                                    of any remuneration paid or payable to the
                                    Employee for any subsequent employment the
                                    Employee may obtain, whether during or after
                                    the period during which the Termination
                                    Payment is made, and the Employee shall have
                                    no obligation whatever to seek any
                                    subsequent employment.

                  (h) PRESERVATION OF CERTAIN PROVISIONS. Notwithstanding any
                  provisions of this Agreement to the contrary, the provisions
                  of Sections 7 through 12 hereof shall survive the expiration
                  or termination of this Agreement as necessary to give full
                  effect to all of the provisions of this Agreement.

         7. NON-COMPETITION BY EMPLOYEE. During the term of this Agreement, the
Employee shall not, directly or indirectly, either as an Employee, Employer,
Consultant, Agent, Principal, Partner, Corporate Officer, Director, Shareholder,
Member, Investor or in any other individual or representative capacity, engage
or participate in any business that is in competition in any manner whatever
with the business of the Company. For these purposes, the business of the
Company is establishing and providing mobile wireless communications services
(the "Business"), including all aspects of the Business, within the Service Area
as that term is defined in the Schedule of Definitions referred to in and
incorporated by reference into the Sprint Agreement. Furthermore, upon the
expiration of this Agreement or the termination of this Agreement prior to
September 30, 2002, for any reason, the Employee expressly agrees not to engage
or participate, directly or indirectly, either as an Employee, Employer,
Consultant, Agent, Principal, Partner, Stockholder, Corporate Officer, Director,
Shareholder, Member, Investor or in any other individual or representative
capacity, for a period of two (2) years in any business that is in competition
with the Business and that is located within and/or doing business within the
Service Area as defined above as in existence during the term of the Employee's
employment with the Company. The parties agree that the Company has a legitimate
interest in protecting the Business and goodwill of the Company that has
developed in the areas of the Company's Business and in the geographical areas
of this Covenant Not To Compete as a result of the operations of the Company.
The parties agree that the Company is entitled to protection of its interests in
these areas. The parties further agree that the limitations as to time,
geographical area, and scope of activity to be restrained do not impose a
greater restraint upon Employee than is necessary to protect the goodwill or
other business interest of the Company. The parties further agree that in the
event of a violation of this Covenant Not To Compete, that the Company shall be
entitled to the recovery of damages from Employee and/or an injunction against
Employee for the breach or violation or continued breach or violation of this
Covenant. The Employee agrees that if a court of competent jurisdiction
determines that the length of time or any other restriction, or portion thereof,
set forth in this Section 7 is overly restrictive and



EMPLOYMENT AGREEMENT              Page 12 of 22
ALAMOSA PCS LLC and Jerry Brantley
<PAGE>   13

unenforceable, the court may reduce or modify such restrictions to those which
it deems reasonable and enforceable under the circumstances, and as so reduced
or modified, the parties hereto agree that the restrictions of this Section 7
shall remain in full force and effect. The Employee further agrees that if a
court of competent jurisdiction determines that any provision of this Section 7
is invalid or against public policy, the remaining provisions of this Section 7
and the remainder of this Agreement shall not be affected thereby, and shall
remain in full force and effect.

         8. EXCEPTIONS TO NON-COMPETITION COVENANTS. Notwithstanding anything
herein to the contrary or apparently to the contrary, the following shall not be
a violation or breach of the non-competition covenants contained in this
Agreement. Employee may invest in the securities of any enterprise (but without
otherwise participating in the activities of such enterprise) if (a) such
securities are listed on any national or regional securities exchange or have
been registered under Section 12(g) of the Securities Exchange Act of 1934 and
(b) the Employee does not beneficially own (as defined in Rule 13d-3 promulgated
under the Securities Exchange Act of 1934) in excess of 5% of the outstanding
capital stock of such enterprise. In addition, employee's investment in any
company or entity in which Employer is an owner or stockholder at the time of
entering into this Amended and Restated Employment Agreement shall also be an
exception to the non-competition covenants. The names of these companies or
entities are shown on the attached Exhibit B, which is incorporated herein by
this reference as if copied at length. Notwithstanding the foregoing, the
Employee's relationship with other entities or business interests of Employee
shall in no way interfere with or detract from the duties of the Employee to the
Company as called for in this Agreement.

         9. CONFIDENTIAL INFORMATION. The Employee recognizes and acknowledges
that he will have access to certain information of members of the Company Group
(as defined below) and that such information is confidential and constitutes
valuable, special and unique property of such members of the Company Group. The
parties agree that the Company has a legitimate interest in protecting the
Confidential Information, as defined below. The parties agree that the Company
is entitled to protection of its interests in the Confidential Information. The
Employee shall not at any time, either during or subsequent to the term of this
Agreement, disclose to others, use, copy or permit to be copied, except in
pursuance of his duties for an on behalf of the Company, it successors, assigns
or nominees, any Confidential Information of any member of the Company Group
(regardless of whether developed by the Employee) without the prior written
consent of the Company. Employee acknowledges that the use or disclosure of the
Confidential Information to anyone or any third party could cause monetary loss
and damages to the Company. The parties further agree that in the event of a
violation of this covenant against non-use and non-disclosure of Confidential
Information, that the Company shall be entitled to a recovery of damages from
Employee and/or an injunction against Employee for the breach or violation or
continued breach or violation of this covenant.

         As used herein, "Company Group" means the Company, and any entity that
directly or indirectly controls, is controlled by, or is under common control
with, the Company, and for purposes of this definition "control" means the
possession, directly or indirectly, of the power to direct or cause the
direction of the management and policies of such entity, whether through the
ownership of voting securities, by contract or otherwise.

         The term "Confidential Information" with respect to any person means
any secret or confidential information or know-how and shall include, but shall
not be limited to, the plans, financial and operating information, customers,
supplier arrangements, contracts, costs, prices, uses, and applications of
products and services, results of investigations, studies or experiments owned
or used by such person, and all apparatus, products, processes, compositions,
samples, formulas, computer programs, computer hardware designs, computer
firmware designs, and servicing, marketing or manufacturing methods and
techniques at any time used, developed, investigated, made or sold by such
person, before or during the term of this Agreement, that are not readily
available to the public or that are maintained as confidential by such person.
The Employee shall maintain in confidence any Confidential Information of third
parties received as a result of his employment with the Company in accordance
with the Company's obligations to such third parties and the policies
established by the Company.

         10. DELIVERY OF DOCUMENTS UPON TERMINATION. The Employee shall deliver
to the Company or its designee at the termination of his employment all
correspondence, memoranda, notes, records, drawings, sketches, plans, customer
lists, product compositions, and other documents and all copies thereof, made,
composed or received by the Employee, solely or jointly with others, that are in
the Employee's possession, custody, or control at termination and that are
related in any manner to the past, present, or anticipated business or any
member of the Company Group. In this regard, the Employee hereby grants and
conveys to the Company all right, title and interest in and to, including
without limitation, the right to possess, print, copy, and sell or otherwise
dispose of, any reports, records, papers, summaries, photographs, drawings or
other documents, and writings, and copies, abstracts or summaries thereof, that
may be prepared by the Employee or under his direction or that may come into his
possession in any way during the term of his employment with the Company that
relate in any manner to the past, present or anticipated business of any member
of the Company Group.

         11. DISPUTES. The Company and Employee agree to the following in regard
to any disputes between them arising under any of the provisions of this
Agreement other than the provisions of Sections 7 through 10 hereof. Nothing in
this Section 11 applies to or governs disputes arising under Sections 7 through

                  (a) MEDIATION. The Company and Employee agree to mediate any
                  dispute arising under the applicable provisions of this
                  Agreement. In the event of any such dispute, the parties,
                  within thirty (30) days of a written request for mediation,
                  shall attend, in good faith, a mediation in order to make a
                  good faith reasonable effort to resolve such dispute arising
                  under this Agreement. The parties shall attempt, in good
                  faith, to agree to a mediator. If unable to so agree, the
                  parties, in that event, will move to arbitration as provided
                  in this Agreement and there will be no mediation. If this good
                  faith mediation effort fails to resolve any dispute arising
                  under this Agreement, the Company and Employee agree to
                  arbitrate any dispute arising under this Agreement. This
                  arbitration shall occur only after the mediation process
                  described herein.

                  (b) ARBITRATION. The Company and Employee agree, as concluded
                  by the parties to this Agreement on the advice of their
                  counsel, and as evidenced by the signatures of the parties and
                  of their respective attorneys, that all questions as to rights
                  and obligations arising under the terms of this Agreement are
                  subject to arbitration and such arbitration shall be governed
                  by the provisions of the Texas General Arbitration Act (Texas
                  Civil Practice and Remedies Code Section 171.001 et seq as it
                  may be amended from time to time).

                  (c) DEMAND FOR ARBITRATION. If a dispute should arise under
                  this Agreement, either party may within thirty (30) days make
                  a demand for arbitration by filing a demand in writing with
                  the other.

                  (d) APPOINTMENT OF ARBITRATORS. The parties to this Agreement
                  may agree on one arbitrator, but in the event that they cannot
                  so agree, there shall be three arbitrators, one named in
                  writing by each of the parties within thirty (30) days after
                  demand for arbitration is made, and a third to be chosen by
                  the two so named. The arbitrators among themselves shall
                  appoint a presiding arbitrator. Should either party fail to
                  timely join in the appointment of the arbitrators, the
                  arbitrators shall be appointed in accordance with the
                  provisions of Texas Civil Practice and Remedies Code Section
                  171.041.

                  (e) HEARING. All arbitration hearings conducted under the
                  terms of this Agreement, and all judicial proceedings to
                  enforce any of the provisions of this Agreement, shall take
                  place in Lubbock County, Texas. The hearing before the
                  arbitrators of the matter to be arbitrated shall be at the
                  time and place within that County selected by the arbitrators
                  or if deemed by the arbitrators to be more convenient for the
                  parties or more economically



EMPLOYMENT AGREEMENT              Page 15 of 22
ALAMOSA PCS LLC and Jerry Brantley

                  feasible, may be conducted in any city within the Service Area
                  as referred to in Section 7 hereof or within the State of
                  Texas.

                  (f) ARBITRATION AWARD. If there is only one arbitrator, his or
                  her decision shall be binding and conclusive. The submission
                  of a dispute to the arbitrators and the rendering of their
                  decision shall be a condition precedent to any right of legal
                  action on the dispute. A judgment confirming the award of the
                  arbitrators may be rendered by any court having jurisdiction;
                  or the court may vacate, modify, or correct the award in
                  accordance with the provisions of the Texas General
                  Arbitration Act (Texas Civil Practice and Remedies Code
                  Section 171.087 et seq as it may be amended from time to
                  time).

                  (g) COSTS OF ARBITRATION. The costs and expenses of
                  arbitration, including the fees of the arbitrators but
                  excluding any attorneys' fees, shall be advanced by the
                  Company, but will ultimately be borne by the losing party or
                  in such proportions as the arbitrators shall determine.

                  (h) CONDUCT OF ARBITRATION. Any arbitration brought under the
                  terms of this Agreement shall be conducted in the following
                  manner:

                           (1) Time Limitations. The parties agree that the
                           following time limitations shall govern the
                           arbitration proceedings conducted under the terms of
                           this Agreement:

                                    (a) Any demand for arbitration must be filed
                                    within thirty (30) days of the date the
                                    mediation is deemed unsuccessful, or thirty
                                    (30) days after the date of the written
                                    request for mediation, whichever is later.

                                    (b) Each party must select an arbitrator
                                    within thirty (30) days of receipt of notice
                                    that an arbitration proceeding has
                                    commenced. In the event that no such
                                    selection is made, the arbitrator selected
                                    by the other party may conduct the
                                    arbitration proceeding without selecting any
                                    other arbitrator.

                                    (c) The hearing must be held within sixty
                                    (60) days of the date on which the third
                                    arbitrator is selected.

                                    (d) Hearing briefs must be submitted no
                                    later than ten (10) days after the hearing.

                           (2) Discovery in Arbitration Proceedings. The parties
                           agree that discovery may be conducted in the course
                           of the arbitration proceeding in accordance with the
                           following provisions:

                                    (a) Each party may notice no more than three
                                    (3) depositions in total, including both
                                    witnesses adherent to the adverse party and
                                    third-party witnesses.

                                    (b) Each party may serve no more than
                                    twenty-five (25) requests for admission on
                                    the other party. No requests may be served
                                    within ten (10) days of the date of hearing,
                                    unless the parties otherwise stipulate. All
                                    requests for admission shall be responded to
                                    within ten (10) days of service of the
                                    requests, unless the parties otherwise
                                    stipulate.

                                    (c) Each party may serve no more than fifty
                                    (50) interrogatories on the other party. No
                                    interrogatory shall contain subparts, or
                                    concern more than one topic or subject of
                                    inquiry. Interrogatories may not be phrased
                                    so as to circumvent the effect of this
                                    clause. No interrogatories may be served
                                    within ten (10) days of the date of hearing,
                                    unless the parties otherwise stipulate. All
                                    interrogatories shall be responded to within
                                    ten (10) days of service of the
                                    interrogatories, unless the parties
                                    otherwise stipulate.

                                    (d) Each party may serve no more than ten
                                    (10) requests for production of documents on
                                    the other party. No request for production
                                    of documents shall contain subparts, or seek
                                    more than one type of document. Requests for
                                    production of documents may not be phrased
                                    so as to circumvent the effect of this
                                    clause. Unless the parties otherwise
                                    stipulate, requests for production of
                                    documents may not be served within ten (10)
                                    day of the date of hearing, and all requests
                                    for production of documents shall be
                                    responded to within ten (10) days of service
                                    of the requests.

                                    (e) If any party contends that the other
                                    party has served discovery requests in a
                                    manner not permitted by this Section, or
                                    that the other party's response to a
                                    discovery request is unsatisfactory, the
                                    party may request the

                                    presiding arbitrator to resolve such
                                    discovery disputes. The presiding arbitrator
                                    shall prescribe the procedure by which such
                                    disputes are resolved. Any discovery dispute
                                    may be handled by telephone conference among
                                    the parties and the presiding arbitrator.

         12. SUCCESSORS; BINDING AGREEMENT; ASSIGNMENT. The Company shall
require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business or
assets of the Company to expressly assume and agree in writing to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession had taken place, provided that the
Employee must be given the position as the President and Chief Operating Officer
("COO") of such successor with the same authority, powers and responsibilities
set forth in Section 1 hereof with respect to the subsidiary or subdivision
which operates the business of the Company as it exists on the date of such
business combination. Upon the First Option Exercise Date (as defined in that
certain Nonqualified Stock Option Agreement between Employee and Holdings
executed contemporaneously with this Agreement), the Company shall be required
to assign all of its rights and obligations hereunder to Holdings and Holdings
shall expressly assume and agree to perform this Agreement in the same manner
and to the same extent that the Company would be required to perform it,
provided that the Employee must be given the position as President and Chief
Operating Officer of Holdings with the same authority, powers and
responsibilities set forth in Section 1 hereof. Failure of the Company to obtain
such express assumption and agreement at or prior to the effectiveness of any
such succession or event shall be a breach of this Agreement and shall entitle
the Employee to compensation and benefits from the Company in the same amount
and on the same terms to which the Employee would be entitled hereunder if the
Company terminated the Employee's employment without Cause, except that all
options will be immediately vested. For purposes of implementing the foregoing,
the date on which any such succession becomes effective shall be deemed the date
of termination. As used in this Agreement, "Company" shall mean the Company as
hereinbefore defined and any successor to its business or assets as aforesaid
which assumes and agrees to perform this Agreement by operation of law, or
otherwise. The Company may not assign this Agreement, (i) except in connection
with, and to the acquiror of, all or substantially all of the business or assets
of the Company, provided such acquiror expressly assumes and agrees in writing
to perform this Agreement as provided in this Section, and (ii) except in
connection with the Company becoming a wholly-owned subsidiary of Holdings, in
which event the Company may assign this Agreement and all of the Company's
rights and obligations hereunder to Holdings. The Employee may not assign his
rights or delegate his duties or obligations under this Agreement.

                  (b) NO ORAL MODIFICATION, WAIVER OR DISCHARGE. No provisions
                  of this Agreement may be modified, waived or discharged

                  designated by the Board of Managers of the Company to execute
                  such a waiver, modification or discharge. No waiver by either
                  party hereto at any time of any breach by the other party
                  hereto of, or failure to be in compliance with, any condition
                  or provision of this Agreement to be performed by such other

                  attached as Exhibits to this Agreement.

                  (c) INVALID PROVISIONS. Should any portion of this Agreement
                  be adjudged or held to be invalid, unenforceable or void, such

                  that the portion so held invalid, unenforceable or void shall,
