                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.   ORGANIZATION:

         Western Wireless Corporation (the "Company") provides wireless
communications services in the western United States principally through the
ownership and operation of cellular and personal communications services ("PCS")
systems. The cellular operations are primarily in rural areas and the PCS
operations are primarily in urban areas due to the Company's belief that there
are certain strategic advantages to operating each technology in these
respective areas. As of June 30, 1998, the Company provides cellular services in
72 Rural Service Areas ("RSA") and 16 Metropolitan Statistical Areas and through
its 80.1% ownership in VoiceStream Wireless Corporation ("VoiceStream"),
formerly known as Western PCS Corporation, provides PCS services in seven Major
Trading Areas ("MTA"). VoiceStream holds limited partnership interests in joint
ventures which own PCS licenses in 21 Basic Trading Areas ("BTA"), one of which
is operational and managed by VoiceStream under its PCS brand name. In
addition, VoiceStream manages another BTA under its PCS brand name.

         The Company expects to incur significant operating losses and to
generate negative cash flows from operating activities during the next several
years while it develops and constructs its PCS systems and builds a PCS customer
base.

         The accompanying interim consolidated financial statements and the
financial information included herein are unaudited, but reflect all adjustments
which are, in the opinion of management, necessary for a fair presentation of
the financial position, results of operations and cash flows for the periods
presented. All such adjustments are of a normal, recurring nature. Results of
operations for interim periods presented herein are not necessarily indicative
of results of operations for the entire year. For further information, refer to
the Company's annual audited financial statements and footnotes thereto for the
year ended December 31, 1997, contained in the Company's Form 10-K dated March
27, 1998.


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

     Loss per common share:

         Loss per common share is calculated using the weighted average number
of shares of outstanding common stock during the period. The number of shares
outstanding has been calculated based on the requirements of Statement of
Financial Accounting Standards No. 128, "Earnings Per Share." Due to the net
loss incurred during the periods presented, all options outstanding are
anti-dilutive, thus basic and diluted loss per share are equal.


     Supplemental cash flow disclosure:

         Non-cash operating activities consisted of a $15.0 million reduction in
other current assets due to the release of restricted cash from escrow for the
final payment on the acquisition of Triad Cellular L.P. and certain of its
affiliates in the first quarter of 1998. Non-cash investing activities consisted
of a $12.3 million contribution of wireless licenses to a joint venture, which
occurred in the first quarter of 1998.

         Cash paid for interest (net of amounts capitalized) was $64.5 million
and $34.2 million for the six months ended June 30, 1998 and 1997, respectively.
There was no interest capitalized for the six months ended June 30, 1998.
Interest capitalized for the six months ended June 30, 1997, was $4.0 million.



     Reclassifications:

         Certain amounts in prior year's financial statements have been
reclassified to conform to the 1998 presentation.

</TABLE>

         The Company has a $950 million credit facility with a consortium of
lenders (the "Credit Facility"), in the form of a $750 million revolving credit
loan (the "Revolver") and a $200 million term loan (the "Term Loan").

         In June 1998, a wholly owned subsidiary of VoiceStream (the "PCS
Borrower") entered into a $1 billion credit facility with a consortium of
lenders (the "PCS Credit Facility"). The PCS Credit Facility consists of $500
million in revolving credit and $250 million in a delayed draw term 
loan (collectively the "PCS Revolver"), and a term loan (the "PCS Term loan") 
for $250 million. The PCS Borrower must borrow the remaining $200 million 
delayed draw portion of the PCS Revolver by December 31, 1998, or lose access 
to such. In addition, the PCS Borrower must raise an additional $200 million 
before gaining access to the remaining $500 million of the PCS Revolver. 
Beginning September 2001, the amount available to borrow under the PCS 
Revolver and the principal balance of the PCS Term Loan are to be reduced by 
various percentages each year. The PCS Revolver and the PCS Term Loan are due 
in their entirety on December 31, 2006 and June 30, 2007, respectively. The PCS 
Credit Facility also contains certain financial covenants, which, among other 
things, impose limitations on the amount of indebtedness, limit the amount of 
capital spending and impose limitations on acquisitions and investments. The 
repayment of the PCS Credit Facility is secured by, among other things, the 
grant of a security interest in substantially all of the assets of the PCS 
Borrower.

         Any loan shall, at the option of the PCS Borrower, be made as a Base
Rate Advance or Eurodollar Advance. Under the PCS Credit Facility, interest is
payable at an applicable margin in excess of the prevailing rate. The applicable
margin on the PCS Credit Facility is determined quarterly based on certain
events and the leverage ratio of the PCS Borrower. During June 1998, all loans
under the PCS Credit Facility had been borrowed using the Eurodollar option. The
PCS Credit Facility also provides for an annual fee ranging from 0.375% to 0.5% 
on the unused commitment, payable quarterly.

         Immediately following the acquisition of the PCS Credit Facility, a
wholly owned subsidiary of VoiceStream paid off, in its entirety, the balance
owed under the $300 million PCS Vendor Facility.

</TABLE>

         Aggregate rental expense for all operating leases was approximately
$7.9 million and $7.2 million for the three months ended June 30, 1998 and 1997,
respectively, and $14.7 million and $13.6 million for the six months ended June
30, 1998 and 1997, respectively.

         In order to ensure adequate supply and availability of certain
inventory requirements and service needs, the Company has committed to purchase
from various suppliers, wireless communications equipment, handsets, and
services. These agreements expire at various dates through the year 2003. The
aggregate amount of these commitments total approximately $573 million. At June
30, 1998, the Company has ordered approximately $362 million under all of these
agreements, of which approximately $32 million is outstanding.

         The Company has various other purchase commitments for materials,
supplies and other items incidental to the ordinary course of business which are
neither significant individually nor in the aggregate. Such commitments are not
at prices in excess of current market value.

5.   MINORITY INTEREST IN CONSOLIDATED SUBSIDIARY:

         In February 1998, the Company and its subsidiary, VoiceStream,
consummated an agreement with Hutchison Telecommuications Limited ("HTL") and a
subsidiary of HTL (the "HTL Sub") pursuant to which the HTL Sub purchased 19.9%
of VoiceStream for an aggregate purchase price of $248.4 million. The Company
and VoiceStream have amended certain outstanding financing agreements to which
they are subject, and unless otherwise agreed to by HTL Sub and the Company,
neither the Company nor VoiceStream shall have any liability regarding any
indebtedness of the other. The HTL Sub has the right to designate two directors
to a ten person Board of Directors of VoiceStream, which directors have 
certain rights with respect to certain transactions and actions of VoiceStream.
As of June 30, 1998, HTL Sub's portion of VoiceStream's net loss was $11.3 
million and $17.1 million for the three and six months ended June 30, 1998, 
respectively.


6.   SHAREHOLDERS' EQUITY:

         During the six months ended June 30, 1998, the Company issued 115,257
shares of its Class A Common Stock as a result of employee stock options that
were exercised.

         In May 1998, the Company completed a secondary offering on form S-3
(the "Secondary Offering") of 13,915,000 Class A Common Stock shares (including
on over-allotment exercised by the underwriters). The Company did not issue any
new primary shares and received no proceeds from the Secondary Offering. The
shares were offered by certain shareholders of the Company who elected to
convert a portion of their Class B Common Stock into publicly traded Class A
Common Stock for sale pursuant to a registration statement. No member of
management of the Company sold any shares in the Secondary Offering.

         In February 1998, the Company received additional paid in capital of
approximately $123.2 million related to the sale of a 19.9% interest in
VoiceStream. This represents the amount in excess of the book value of
VoiceStream for the 19.9% interest purchased by the HTL Sub.

         In January 1998, the Company issued 100,000 Class A Common Stock shares
to certain key executives pursuant to an Executive Restricted Stock Plan.


7.   ACQUISITIONS AND OTHER TRANSACTIONS:

         In the second quarter of 1998, the Company purchased the Nebraska 5 RSA
for approximately $15.5 million in cash. Prior to the purchase of the Nebraska 5
RSA, the Company operated this market under an Interim Operating Authority from
the Federal Communications Commission ("FCC").

         In June 1998, a wholly owned subsidiary of the Company, through a
controlling interest in a partnership (the "Ireland Partnership"), was notified
by the Office of the Director of Telecommunications Regulation that it was the
preferred applicant for a DCS-1800/GSM 900 mobile communications license in 
Ireland. The amount bid by the Ireland Partnership on this license was $16.2 
million, including related fees. The license has not yet been granted and the 
terms of the purchase are in the process of being negotiated.

         During the second quarter of 1998, Cook Inlet Western Wireless PV/SS
PCS, LP ("Cook Inlet PCS"), a partnership in which a subsidiary of VoiceStream
holds a 49.9% limited partnership interest, participated in the C Block
restructuring options provided by the FCC. The FCC provided for various options,
two of which were, 1) the option to return to the FCC entire licenses purchased
in the C Block auction and be relieved of 100% of the related debt ("Amnesty")
or, 2) to return 15 mhz, from a total of 30 mhz, of the licenses purchased in
the auction and be relieved of one half of the related debt ("Dissagregation").
Of the licenses purchased in the C Block auction Cook Inlet PCS chose Amnesty
for the two BTAs in the Dallas MTA and Dissagregation for the remaining 11
BTA licenses. This resulted in a reduction of Cook Inlet PCS's debt of $29.1 
million and a gain of $3.9 million, due to the retroactive adjustment of 
interest due on the related debt, the effect of which reduced the equity 
losses picked up by the Company for the second quarter operations.

7.   ACQUISITIONS AND OTHER TRANSACTIONS - (CONTINUED):

         Additionally, in July 1998, VoiceStream entered into an agreement to
form a joint venture with third parties that will operate certain PCS licenses
in the south Texas region under the VoiceStream brand name. VoiceStream's
ownership percentage will be less than 25% with an initial contribution to the
venture of certain licenses that it purchased in the FCC's D and E Block
auction valued at approximately $2.5 million. 

         In the first quarter of 1998, the Company was granted 52 Local
Multipoint Distribution Service (LMDS) licenses that it was the high bidder on
in an FCC auction. The Company paid approximately $14.9 million for these
licenses.

         The following is a discussion and analysis of the consolidated
financial condition and results of operations of the Company and should be read
in conjunction with the Company's consolidated financial statements and notes
thereto and other financial information included herein and in the Company's
annual report on Form 10-K for the year ended December 31, 1997. As a result of
acquisitions and due to the phase of the business cycle of the Company's PCS
operations, the Company's operating results for prior periods may not be
indicative of future performance.


OVERVIEW

         The Company provides wireless communications services in the western
United States through the ownership and operation of cellular and personal
communication services ("PCS") systems. The Company owns and operates cellular
communications systems in 88 markets. Through its 80.1% ownership of VoiceStream
Wireless Corporation ("VoiceStream"), the Company owns and operates PCS systems
in seven Major Trading Areas ("MTA"). VoiceStream owns an additional 104 PCS
Basic Trading Areas ("BTA") licenses which are not operational. VoiceStream
holds limited partnership interests in joint ventures which own PCS licenses in
21 BTAs, one of which is operational and managed by VoiceStream under it's PCS
brand name. The results of operations of these joint ventures are not included
in the following discussion of PCS operations. In addition, VoiceStream manages
another BTA under it's PCS brand name.

         In the comparisons that follow, the Company has separately set forth
certain information relating to cellular operations (including paging) and PCS
operations. The Company believes that this is appropriate because its cellular
systems have been operating for a number of years and operate in rural markets
while its PCS systems did not commence operations until 1996 and operate in
urban markets.


RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED JUNE 30, 1998 AND 1997

CELLULAR OPERATIONS

         The Company had 583,300 cellular subscribers at June 30, 1998,
representing an increase of 36,200 or 6.6% from March 31, 1998. At June 30,
1997, the Company had 389,900 cellular subscribers representing an increase of
38,700 or 11.0% from March 31, 1997.

         During the fourth quarter of 1997, the Company purchased from Triad
Cellular L.P. and certain of its affiliates (collectively "Triad"), the cellular
business and assets of 12 Rural Service Areas ("RSA") in Texas, Utah, Oklahoma
and Minnesota. Therefore, the operating results of the Company's cellular
business compared to the periods prior to this purchase may not be indicative of
future performance.

</TABLE>

         CELLULAR REVENUES

         The increase in subscriber revenues is primarily due to the growth in
the number of subscribers offset by a decrease in the average monthly subscriber
revenue per average subscriber. Average monthly subscriber revenue per average
subscriber was $47.63 for the three months ended June 30, 1998, a 9.2% decline
from $52.46 for the three months ended June 30, 1997. Over the past few years
the cellular industry as a whole has also shown a decline in the average monthly
cellular subscriber revenue per subscriber.

         The increase in roamer revenues is attributed to a normal seasonal
increase in roaming traffic and partially offset by a decrease in the rates
charged between carriers. A significant portion of the increase in roaming
traffic is a result of the acquisition of the Triad RSAs. While the Company
expects total roamer minutes to continue increasing, the decline in the rates
charged between carriers will limit the growth of roamer revenues.

         Equipment sales, which consists primarily of handset sales, increased
primarily due to the increase in the number of handsets sold offset by a
decrease in the average handset sales price.

         CELLULAR OPERATING EXPENSES

         The increase in cost of service is primarily attributable to the
increased costs of maintaining the Company's expanding wireless network to
support the larger subscriber base, offset by a slight reduction in the rates
paid by the Company to access local exchange and long distance carrier
facilities. While cost of service increased, it decreased as a percentage of
service revenues to 14.4% for the three months ended June 30, 1998, from 16.6%
for the three months ended June 30, 1997, which is due primarily to efficiencies
gained from the growing subscriber base.

         Cost of equipment sales increased primarily due to the increase in
handsets sold, offset by a decrease in the average cost of handsets, for the
three months ended June 30, 1998, compared to the three months ended June 30,
1997.

         The Company's general and administrative costs are principally variable
costs, that is costs that will vary with the level of subscribers. The increase
in total dollars is primarily attributable to the increase in costs associated
with supporting a larger subscriber base. While the general and administrative
cost per average subscriber typically will decrease due to efficiencies gained
from a larger subscriber base, the general and administrative cost per average
subscriber increased to $12.85 for the three months ended June 30, 1998,
compared to $11.65 for the three months ended June 30, 1997. This increase is
the result of one time events that occurred in the second quarter of 1998,
including a secondary offering of the Company's common stock (Note 6 to this
quarter's consolidated financial statements) and a billing system conversion for
the former Triad subscribers.

         The increase in sales and marketing costs is primarily due to the
increase in subscribers added during the three months ended June 30, 1998,
compared to the three months ended June 30, 1997. Sales and marketing cost per
net subscriber added, including the loss on equipment sales, increased to $656
for the three months 


                                       12
<PAGE>   13

ended June 30, 1998, from $500 for the three months ended June 30, 1997. This
increase is largely due to a growth in disconnected subscribers causing the 
increase in costs to be spread over a similar amount of net subscriber 
additions as in the prior year. The growth in disconnected subscribers is a 
result of a slightly higher churn rate (representing customer attrition) 
applied to a larger subscriber base.

         The increase in depreciation and amortization expenses is attributable
to the continued expansion of the Company's cellular systems including the
acquisition of the Triad properties.

         PCS OPERATIONS

         The Company commenced its PCS operations in its first MTA in February
1996. Since that time, the Company has commenced operations in its six remaining
MTAs on various dates through May of 1997. Due to the various dates at which
each of the MTAs became operational, the revenues and expenses incurred may not
be representative of future operations. Additionally, during each period being
discussed, a portion of the operating expenses incurred in the Company's PCS
operations were related to start-up costs incurred prior to the commencement of
operations in each of the systems. Exclusive of depreciation and amortization
expense, which was not material, approximately $1.0 million of start-up costs
were incurred for the three months ended June 30, 1998, compared to $1.5 million
for the three months ended June 30, 1997. Start-up costs incurred in the second
quarter of 1998, primarily relate to non-construction costs incurred in the
effort to get the Seattle and Phoenix BTAs ready for operation.

         The Company had 212,600 PCS subscribers at June 30, 1998, representing
an increase of 48,000 or 29.2% from March 31, 1998. At June 30, 1997, the
Company had 74,400 PCS subscribers, representing an increase of 25,400 or 51.8%
from March 31, 1997.

         PCS REVENUES

         The increase in service revenues is due to the increase in the number
of subscribers offset by a decrease in the average monthly subscriber revenue
per average subscriber. The increase in subscribers is due to the relative
maturity of the seven MTAs operating in the second quarter of 1998, the same
seven MTAs that were operating in the second quarter of 1997, and the Company's
"Get More" advertising campaign, featuring Jamie Lee Curtis, that was initiated
in the second quarter of 1998. Average monthly subscriber revenue per average
subscriber was $47.44 for the three months ended June 30, 1998, compared to
$68.64 for the three months ended June 30, 1997. The decrease in the average
monthly subscriber revenue per average subscriber is primarily due to the
relative maturity of the competitive environment in each of the operating
markets.

         Equipment sales increased primarily as a result of increased sales of
handsets, offset by a decrease in the average handset selling price. While the
Company expects total equipment sales to continue to increase, the decline in
the average handset selling price will limit the growth of equipment sales.

         PCS OPERATING EXPENSES

         Cost of service expenses, cost of equipment sales, and depreciation and
amortization expenses largely represent the expenses incurred by the operational
PCS systems. Accordingly, cost of service expenses, cost of equipment sales, and
depreciation and amortization expenses increased for the three months ended June
30, 1998, compared to the three months ended June 30, 1997. The relatively low
increase in cost of service is related to efficiencies gained from the growing
subscriber base as well as a reduction in rates paid by the Company to access
local exchange and long distance carrier facilities.

         General and administrative costs increased due to the costs associated
with supporting the additional operating markets and larger subscriber base.
However, general and administrative costs per average subscriber decreased to
$35.49 for the three months ended June 30, 1998, compared to $68.51 for the same
quarter in 1997. This decrease is the result of efficiencies gained from a
growing subscriber base.

         Sales and marketing costs increased as a result of the increase in net
subscriber additions and the effort to promote the Company's PCS brand name in a
greater number of markets. However, the sales and marketing cost per net
subscriber added, including the loss on equipment sales, decreased to $544 for
the three months ended June 30, 1998, from $1,033 for the same quarter in 1997.
This decrease is largely the result of a decrease in the churn rate in the
second quarter of 1998, compared to the same quarter in 1997. In addition, the
Company is seeing cost efficiencies from an increased growth in subscribers.


OTHER INCOME (EXPENSE)

         Interest and financing expense increased to $30.6 million for the three
months ended June 30, 1998, compared to $23.1 million for the three months ended
June 30, 1997, due to the increase in long-term debt. Long-term debt was
incurred primarily to fund the Company's capital expenditures associated with
the build-out of the Company's PCS systems. Interest expense will continue to
increase in 1998 as a result of increased borrowings the Company has incurred,
and will continue to incur, to fund this expansion. The weighted average
interest rate, before the effect of capitalized interest, was 9.1% and 9.9% for
the three months ended June 30, 1998 and 1997, respectively.


EBITDA

          "EBITDA" represents operating loss before depreciation and
amortization. EBITDA is a measure commonly used in the industry and should not
be construed as an alternative to operating income (loss) (as determined in
accordance with United States generally accepted accounting principles, "GAAP"),
as an alternative to cash flows from operating activities (as determined in
accordance with GAAP), or as a measure of liquidity. Cellular EBITDA represents
EBITDA from the Company's cellular operations and PCS EBITDA represents EBITDA
from the Company's PCS operations.

         Consolidated EBITDA for the Company increased to $5.7 million for the
three months ended June 30, 1998, from negative $12.1 for the three months ended
June 30, 1997. This increase is due to the $35.9 million and $25.0 million
cellular EBITDA for the three months ended June 30, 1998 and 1997, respectively,
offset by a negative $30.3 million and negative $37.1 million PCS EBITDA for the
three months ended June 30, 1998 and 1997, respectively. The increase in
cellular EBITDA is primarily a result of increased revenues due to the increased
subscriber base and the related cost efficiencies gained. As a result, cellular
operating margin (cellular EBITDA as a percentage of cellular service revenues)
increased to 37.8% for the three months ended June 30, 1998, from 36.4% for the
three months ended June 30, 1997.

RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997

CELLULAR OPERATIONS

         The Company had 583,300 cellular subscribers at June 30, 1998,
representing an increase of 63,300 or 12.2% from December 31, 1997. At June 30,
1997, the Company had 389,900 cellular subscribers representing an increase of
65,700 or 20.3% from December 31, 1996.

         During the fourth quarter of 1997, the Company purchased from Triad
Cellular L.P. and certain of its affiliates (collectively "Triad"), the cellular
business and assets of 12 Rural Service Areas ("RSA") in Texas, Utah, Oklahoma
and Minnesota. Therefore, the operating results of the Company's cellular
business compared to the periods prior to this purchase may not be indicative of
future performance.

         The following table sets forth certain financial data as it relates to
the Company's cellular operations:

</TABLE>

         CELLULAR REVENUES

         The increase in subscriber revenues is primarily due to the growth in
the number of subscribers offset by a decrease in the average monthly subscriber
revenue per average subscriber. Average monthly subscriber revenue per average
subscriber was $47.38 for the six months ended June 30, 1998, a 6.5% decline
from $50.69 for the six months ended June 30, 1997. Over the past few years the
cellular industry as a whole has also shown a decline in the average monthly
cellular subscriber revenue per subscriber.

         The increase in roamer revenues is attributed to an increase in roaming
traffic and partially offset by a decrease in the rates charged between
carriers. A significant portion of the increase in roaming traffic is a result
of the acquisition of the Triad RSAs. While the Company expects total roamer
minutes to continue increasing, the decline in the rates charged between
carriers will limit the growth of roamer revenues.

         Equipment sales, which consist primarily of handset sales, decreased
primarily due to the decrease in the average handset sales price, offset by the
increase in the number of handsets sold.

         CELLULAR OPERATING EXPENSES

         The increase in cost of service is primarily attributable to the
increased costs of maintaining the Company's expanding wireless network to
support the larger subscriber base, offset by a reduction in the rates paid by
the Company to access local exchange and long distance carrier facilities. While
cost of service dollars increased slightly, it decreased as a percentage of
service revenues to 14.0% for the six months ended June 30, 1998, from 17.8% for
the six months ended June 30, 1997, which is due primarily to efficiencies
gained from the growing subscriber base.



                                       15
<PAGE>   16

         Cost of equipment sales increased primarily due to the increase in
handsets sold, offset by a decrease in the average cost of handsets, for the six
months ended June 30, 1998, compared to the six months ended June 30, 1997.

         The Company's general and administrative costs are principally
considered to be variable costs, that is costs that will vary with the level of
subscribers. The increase is primarily attributable to the increase in costs
associated with supporting the increased subscriber base. While the general and
administrative cost per average subscriber typically will decrease due to
efficiencies gained from a larger subscriber base, the general and
administrative cost per average subscriber increased to $12.70 for the six
months ended June 30, 1998, compared to $12.49 for the six months ended June 30,
1997. This increase is the result of one time events that occurred in the second
quarter of 1998, including a secondary offering of the Company's common stock 
(Note 6 to this quarter's consolidated financial statements) and a billing
system conversion for the former Triad subscribers.

         The increase in sales and marketing costs is primarily due to the
increase in subscribers added during the six months ended June 30, 1998,
compared to the six months ended June 30, 1997. Sales and marketing cost per net
subscriber added (excluding subscribers added from acquisitions), including the
loss on equipment sales, increased to $729 for the six months ended June 30,
1998, from $524 for the six months ended June 30, 1997. This increase is largely
to a growth in disconnected subscribers causing the increase in costs to be
spread over a similar amount of net subscriber additions as in the prior year.
The growth in disconnected subscribers is a result of a slightly higher churn
rate (representing customer attrition) applied to a larger subscriber base.

         The increase in depreciation and amortization expenses is attributable
to the continued expansion of the Company's cellular systems including the
acquisition of the Triad properties.

         PCS OPERATIONS

         The Company commenced its PCS operations in its first MTA in February
1996. Since that time, the Company has commenced operations in its six remaining
MTAs on various dates through May of 1997. Due to the various dates at which
each of the MTAs became operational, the revenues and expenses incurred may not
be representative of future operations. Additionally, during each period being
discussed, a portion of the operating expenses incurred by the Company's PCS
operations were related to start-up costs incurred prior to the commencement of
operations in each of the systems. Exclusive of depreciation and amortization
expense, which was not material, approximately $1.6 million of start-up costs
were incurred for the six months ended June 30, 1998, compared to $3.9 million
for the six months ended June 30, 1997. Start-up costs incurred in the six
months ended June 1998, primarily relate to non-construction costs incurred in
the effort to get the Seattle and Phoenix BTAs ready for operation.

         The Company had 212,600 PCS subscribers at June 30, 1998, representing
an increase of 84,000 or 65.3% from December 31, 1997. At June 30, 1997, the
Company had 74,400 PCS subscribers, representing an increase of 38,900 or 109.6%
from December 31, 1996.

         PCS REVENUES

         The increase in service revenues is due to the increase in the number
of subscribers offset by a decrease in the average monthly subscriber revenue
per average subscriber. The increase in subscribers is due to the relative
maturity of the seven MTAs operating in the six months ended June 30, 1998,
compared to the same seven MTAs that were operating in the six months ended June
30, 1997. Average monthly subscriber revenue per average subscriber was $47.85
for the six months ended June 30, 1998, compared to $64.44 for the six months
ended June 30, 1997.

         Equipment sales increased primarily as a result of increased sales of
handsets, offset by a decrease in the average handset selling price. While the
Company expects total equipment sales to continue to increase, the decline in
the average handset selling price will limit the growth of equipment sales.

         PCS OPERATING EXPENSES

         Cost of service expenses, cost of equipment sales, and depreciation and
amortization expenses largely represent the expenses incurred by the operational
PCS systems. Accordingly, cost of service expenses, cost of equipment sales, and
depreciation and amortization expenses increased for the six months ended June
30, 1998, compared to the six months ended June 30, 1997. The relatively low
increase in cost of service is related to efficiencies gained from the growing
subscriber base as well as a reduction in rates paid by the Company to access
local exchange and long distance carrier facilities.

         General and administrative costs increased due to the costs associated
with supporting the additional operating markets and larger subscriber base.
However, general and administrative costs per average subscriber decreased to
$37.38 for the six months ended June 30, 1998, compared to $76.87 for the same
period in 1997. This decrease is the result of efficiencies gained from a
growing subscriber base.

         Sales and marketing costs increased as a result of the increase in net
subscriber additions and the effort to promote the Company's PCS brand name in a
greater number of markets. However, the sales and marketing cost per net
subscriber added, including the loss on equipment sales, decreased to $569 for
the six months ended June 30, 1998, from $1,075 for the same period in 1997.
This decrease is largely the result of a decrease in the churn rate for the 
six months ended June 30, 1998, compared to the same period in 1997. In
addition, the Company is seeing cost efficiencies from an increased growth in
subscribers.



OTHER INCOME (EXPENSE)

         Interest and financing expense increased to $61.8 million for the six
months ended June 30, 1998, compared to $40.5 million for the six months ended
June 30, 1997, due to the increase in long-term debt. Long-term debt was
incurred primarily to fund the Company's capital expenditures associated with
the build-out of the Company's PCS systems. Interest expense will continue to
increase in 1998 as a result of increased borrowings the Company has incurred,
and will continue to incur, to fund this expansion. The weighted average
interest rate, before the effect of capitalized interest, was 9.1% and 10.1% for
the six months ended June 30, 1998 and 1997, respectively.


EBITDA

         Consolidated EBITDA for the Company increased to $11.0 million for the
six months ended June 30, 1998, from negative $23.0 for the six months ended
June 30, 1997. This increase is due to the $69.5 million and $42.6 million
cellular EBITDA for the six months ended June 30, 1998 and 1997, respectively,
offset by a negative $58.5 million and negative $65.7 million PCS EBITDA for the
six months ended June 30, 1998 and 1997, respectively. The increase in cellular
EBITDA is primarily a result of increased revenues due to the increased
subscriber base and the related cost efficiencies gained. As a result, cellular
operating margin (cellular EBITDA as a percentage of cellular service revenues)
increased to 38.0% for the six months ended June 30, 1998, from 33.8% for the
six months ended June 30, 1997.

LIQUIDITY AND CAPITAL RESOURCES

         The Company has a credit facility (the "Credit Facility") with a
consortium of lenders providing for $750 million of revolving credit and a $200
million term loan. A wholly owned subsidiary of VoiceStream (the "PCS Borrower")
also has a credit facility (the "PCS Credit Facility") with a consortium of
lenders providing for $500 million of revolving credit and $500 million of term
loans. As of June 30, 1998, $615 million and $300 million were outstanding under
the Credit Facility and the PCS Credit Facility, respectively. Amounts available
for borrowing under the Credit Facility and the PCS Credit Facility, which are
limited by certain financial covenants and other restrictions, were $335 million
and $200 million, respectively. Indebtedness under the Credit Facility matures
on March 31, 2006. The PCS Credit Facility matures on December 31, 2006, for the
revolver and one $250 million term loan, and June 30, 2007 for the other $250
million term loan. Both the Credit Facility and the PCS Credit Facility bear
interest at variable rates. Substantially all the assets of the Company, other
than certain PCS licenses acquired in the Federal Communications Commission's
("FCC") D and E Block auctions and certain other assets, are pledged as security
for such indebtedness. The terms of the Credit Facility and the PCS Credit
Facility restrict, among other things, the sale of assets, distribution of
dividends or other distributions and loans.

         In February 1998, a subsidiary of Hutchison Telecommunications Limited
("HTL") purchased 19.9% of the outstanding capital stock of VoiceStream for an
aggregate purchase price of $248.4 million. Approximately $135 million of the
proceeds are for use by VoiceStream to continued the build-out of its PCS
systems during 1998. The remainder of the proceeds was paid to the Company as a
repayment of advances made to VoiceStream and was used by the Company to reduce
amounts outstanding under the Credit Facility.

         In June, 1998, a wholly owned subsidiary of the Company, through a
controlling interest in a partnership (the "Ireland Partnership"), was notified
by the Office of the Director of Telecommunications Regulation that it was the
preferred applicant for a DCS-1800/GSM 900 mobile communications license in 
Ireland. The amount bid by the Ireland Partnership on this license was $16.2 
million, including related fees. The license has not yet been granted and the 
terms of the purchase are under negotiation.

         During the remainder of 1998, the Company anticipates spending
approximately $230 million on the construction of the build-out of the
Seattle-Tacoma, Phoenix and Tucson BTA systems, to provide funds to Cook Inlet
Western Wireless PV/SS PCS, LP ("Cook Inlet PCS") for the build-out of certain
BTA markets, and to expand the build-out of its PCS MTA systems. The Company
will utilize the remaining net proceeds of the HTL investment, other cash on
hand, the PCS Credit Facility and other sources of funding, for such purposes.
In addition, further funds (which may be significant) will be required to
finance the continued growth of its cellular and PCS operations, provide for
working capital and service debt. The Company believes such sources will be
sufficient for the operations of the business. The Company continues to consider
and expects to pursue additional sources of funding to enable the further
development of the PCS business. Such sources may included the issuance of
additional indebtedness and/or the sale of additional equity at the parent or
subsidiary level. There can be no assurance that such funds will be available to
the Company on acceptable or favorable terms.

         Net cash used in operating activities was $29.1 million for the six
months ended June 30, 1998. Adjustments to the $117.2 million net loss to
reconcile to net cash used in operating activities included $75.2 million of
depreciation and amortization, $14.1 million for the equity in net loss of
unconsolidated affiliates due to the increase in activity in the Company's
interest in Cook Inlet PCS, and a $8.9 million decrease in inventory as a result
of a conscious effort to decrease inventory levels from December 1997. Net cash
used in operating activities was $52.1 million for the six months ended June 30,
1997.

         Net cash used in investing activities was $111.5 million for the six
months ended June 30, 1998. Investing activities for such period consisted
primarily of purchases of property and equipment of $63.5 million, of which
$44.0 million was attributable to PCS capital expenditures, and $18.9 million of
additions to licensing costs and other intangible assets, primarily attributable
to 52 Local Multipoint Distribution Service (LMDS) licenses that the Company was
the high bidder on in an FCC auction. In addition, acquisitions of wireless
properties of $16.8 million in the six months ended June 30, 1998, consists
primarily of the Company's purchase of the Nebraska 5 RSA in the second quarter.
Net cash used in investing activities was $309.1 million for the six months
ended June 30, 1997.

         Net cash provided by financing activities was $159.6 million for the
six months ended June 30, 1998. Financing activities for such period consisted
primarily of net proceeds from the sale of a minority interest in



                                       18

VoiceStream of $243.7 million, and the net reduction of long-term debt of $80
million. Net cash provided by financing activities was $322.6 million for the
six months ended June 30, 1997.

         In the ordinary course of business, the Company continues to evaluate
acquisition opportunities, joint ventures and other potential business
transactions. Such acquisitions, joint ventures and business transactions may be
material. Such transactions may also require the Company to seek additional
sources of funding through the issuance of additional debt and/or additional
equity at the parent or subsidiary level. There can be no assurance that such
funds will be available to the Company on acceptable or favorable terms.

         A wholly owned subsidiary of VoiceStream holds a 49.9% interest in Cook
Inlet PCS. Cook Inlet PCS is subject to the FCC's build-out requirements and
will require significant additional amounts to complete the build-out of its PCS
systems and to meet the government debt service requirements on the C and F
Block license purchase prices. The potential sources of such additional funding
include vendor loans, loans or capital contributions by the partners of Cook
Inlet PCS or other third party financing. To date, the Company has funded the
operations of Cook Inlet PCS through the issuance of promissory notes. At June
30, 1998, the wholly owned subsidiary of VoiceStream had advanced funds totaling
$42.5 million to Cook Inlet PCS under such promissory notes. During the second
quarter of 1998, Cook Inlet PCS participated in the C Block restructuring 
options provided by the FCC. The options chosen by Cook Inlet PCS had the 
effect of reducing its debt by $29.1 million.


         YEAR 2000 ISSUES

         The Company, like most owners of computer software, will be required to
modify significant portions of its software so that it will function properly in
the year 2000. Any of the Company's, or its vendors, computer programs that 
have date-sensitive software may recognize a date using "00" as the year 1900 
rather than the year 2000. This could result in a system failure or 
miscalculations causing disruptions of operations, including, among other 
things, a temporary inability to process transactions, send invoices, or 
engage in similar normal business activities. The Company is in the final 
planning phase of its year 2000 compliance project, however does not, as of 
yet, have a determinable estimate of the costs to be incurred. The Company 
expects to incur internal staff costs as well as consulting and other expenses 
related to infrastructure and facilities enhancements necessary to prepare the 
systems for the year 2000.  Costs incurred to date have been insignificant. The 
Company and its vendors expect their year 2000 compliance project to be 
completed on a timely basis,however in the event that the Company or its major 
vendors fail to become compliant by the start of the year 2000, the Company is 
in the process of developing a contingency plan that will limit its risk for 
material loss.

(Houston time) in order for such Business Day to count toward the minimum number
of Business Days required.

          (b) Base Rate Advances.

                   (i) Initial Advances. The Borrower shall give the
          Administrative Agent in the case of Base Rate Advances at least one
          (1) Business Day's irrevocable prior written notice in the form of a
          Request for Advance, or telephonic notice followed immediately by a
          Request for Advance; provided, however, that the Borrower's failure to
          confirm any telephonic notice


                                       27

<PAGE>   29
          with a Request for Advance shall not invalidate any notice so given.

                   (ii) Repayments and Reborrowings. Upon at least one (1), with
          respect to items (A) and (C) of this sentence, or three (3), with
          respect to item (B) of this sentence, Business Days' irrevocable prior
          written notice to the Administrative Agent, the Borrower may repay or
          prepay a Base Rate Advance without regard to its Payment Date and (A)
          reborrow all or a portion of the principal amount thereof as one or
          more Base Rate Advances, (B) reborrow all or a portion of the
          principal thereof as one or more Eurodollar Advances, or (C) not
          reborrow all or any portion of such Base Rate Advance at that time. On
          the date indicated by the Borrower, such Base Rate Advance shall be so
          repaid and, as applicable, reborrowed. Failure of the Borrower to
          provide notice hereunder shall not affect its obligation to repay the
          applicable Eurodollar Advance on such Payment Date.

          (c) Eurodollar Advances.

                          (i) Initial Advances. The Borrower shall give the
          Administrative Agent in the case of Eurodollar Advances at least three
          (3) Business Days' irrevocable prior written notice in the form of a
          Request for Advance, or telephonic notice followed immediately by a
          Request for Advance; provided, however, that the Borrower's failure to
          confirm any telephonic notice with a Request for Advance shall not
          invalidate any notice so given. The Administrative Agent, whose
          determination shall be conclusive absent manifest error, shall
          determine the available Eurodollar Bases and shall notify the Borrower
          of such Eurodollar Bases. The Borrower shall promptly notify the
          Administrative Agent by telephone or telecopy, and shall immediately
          confirm any such telephonic notice in writing, of its selection of a
          Eurodollar Basis and Interest Period for such Advance; provided,
          however, that the Borrower's failure to confirm any such telephonic
          notice in writing shall not invalidate any notice so given.

                         (ii) Repayments and Reborrowings. At least three (3)
          Business Days prior to the Payment Date for a Eurodollar Advance, the
          Borrower shall give the Administrative Agent written notice specifying
          whether all or a portion of such Eurodollar Advance outstanding on the
          Payment Date (A) is to be repaid and then reborrowed in whole or in
          part as a Eurodollar Advance,


                                       28

<PAGE>   30
          and the Interest Period selected, (B) is to be repaid and then
          reborrowed in whole or in part as a Base Rate Advance or (C) is to be
          repaid and not reborrowed at that time. Upon such Payment Date such
          Eurodollar Advance will, subject to the provisions hereof, be so
          repaid and, as applicable, reborrowed.


          (d) Notification of Lenders. Upon receipt of a Request for Advance, or
a notice from the Borrower with respect to a selection of an Interest Period, or
a notice from the Borrower with respect to any outstanding Advance prior to the
Payment Date for such Advance, the Administrative Agent shall promptly notify
each Lender by telephone or telecopy of the contents thereof and the amount of
such Lender's portion of the Advance. Each Lender shall, not later than 1:30
p.m. (Houston time) on the date of borrowing specified in such notice, make
available to the Administrative Agent at the Administrative Agent's Office, or
at such account as the Administrative Agent shall designate, the amount of its
portion of any Advance which represents an additional borrowing hereunder in
immediately available funds.

          (e) Disbursement.

                          (i) Prior to 3:00 p.m. (Houston time) on the date of
          an Advance hereunder, the Administrative Agent shall, subject to the
          satisfaction of any applicable conditions set forth in Article 3
          hereof, disburse the amounts made available to it by the Lenders in
          like funds by (a) transferring the amounts so made available by wire
          transfer pursuant to the Borrower's instructions, or (b) in the
          absence of such instructions, crediting the amounts so made available
          to the account of the Borrower maintained with the Administrative
          Agent.

                         (ii) Unless the Administrative Agent shall have
          received notice from a Lender prior to 2:00 p.m. (Houston time) on the
          date of any Advance that such Lender will not make available to the
          Administrative Agent such Lender's ratable portion of such Advance,
          the Administrative Agent may assume that such Lender has made or will
          make such portion available to the Administrative Agent on the date of
          such Advance and the Administrative Agent may in its sole discretion
          and in reliance upon such assumption, make available to the Borrower
          on such date a corresponding amount. If and to the extent the Lender
          does not make such ratable


                                       29

<PAGE>   31
          portion available to the Administrative Agent, such Lender agrees to
          repay to the Administrative Agent on demand such corresponding amount
          together with interest thereon, for each day from the date such amount
          is made available to the Borrower until the date such amount is repaid
          to the Administrative Agent, at the Federal Funds Rate for the first
          three (3) days and thereafter at the Federal Funds Rate plus one
          percent (1%).

                        (iii) If such Lender shall repay to the Administrative
          Agent such corresponding amount, such amount so repaid shall
          constitute such Lender's portion of the applicable Advance for
          purposes of this Agreement. If such Lender does not repay such
          corresponding amount immediately upon the Administrative Agent's
          demand therefor, the Administrative Agent shall notify the Borrower
          and the Borrower shall immediately pay such corresponding amount to
          the Administrative Agent, together with interest thereon. The failure
          of any Lender to fund its portion of any Advance shall not relieve any
          other Lender of its obligation hereunder to fund its respective
          portion of the Advance on the date of such borrowing, but no Lender
          shall be responsible for any such failure of any other Lender.

                         (iv) In the event that, at any time when the Borrower
          is not in Default and has satisfied all applicable conditions set
          forth in Article 3 hereof, a Lender for any reason fails or refuses to
          fund its portion of an Advance, then, until such time as such Lender
          has funded its portion of such Advance, or all other Lenders have
          received payment in full (whether by repayment or prepayment) of the
          principal and interest due in respect of such Advance, such
          non-funding Lender shall not have the right (i) to vote regarding any
          issue on which voting is required or advisable under this Agreement or
          any other Loan Document and the amount of the Revolving Loan
          Commitment and Term Loans, as applicable, or Loans, as applicable,
          held by such Lender shall not be counted as outstanding for purposes
          of determining "Majority Lenders" hereunder, and (ii) to receive
          payments of principal, interest or fees from the Borrower in respect
          of its unfunded portion of Advances.

          Section 2.3 Interest.

          (a) On Base Rate Advances. Interest on each Base Rate Advance shall be
computed on the basis of a year of 365/366


                                       30

<PAGE>   32
days for the actual number of days elapsed and shall be payable at the Base Rate
Basis for such Advance, in arrears on the applicable Payment Date for the period
through the date immediately preceding such Payment Date. Interest on Base Rate
Advances then outstanding shall also be due and payable on the Revolving Loan
Maturity Date with respect to Revolving Loans and Tranche A Term Loans, and on
the Final Maturity Date with respect to the Tranche B Term Loans.

          (b) On Eurodollar Advances. Interest on each Eurodollar Advance shall
be computed on the basis of a 360-day year for the actual number of days elapsed
and shall be payable at the Eurodollar Basis for such Advance, in arrears on the
applicable Payment Date for the period through the day immediately preceding
such Payment Date, and, in addition, if the Interest Period for a Eurodollar
Advance exceeds three (3) months, interest on such Eurodollar Advance shall also
be due and payable in arrears on every three-month anniversary of the beginning
of such Interest Period. Interest on Eurodollar Advances then outstanding shall
also be due and payable on the Revolving Loan Maturity Date with respect to
Revolving Loans and Tranche A Term Loans and on the Final Maturity Date with
respect to the Tranche B Term Loans.

          (c) Interest if No Notice of Selection of Interest Rate Basis. With
respect to Revolving Loans, if the Borrower fails to give the Administrative
Agent timely notice of its selection of a Eurodollar Basis, or if for any reason
a determination of a Eurodollar Basis for any Advance is not timely concluded,
the Base Rate Basis shall apply to such Advance. With respect to the Term Loans,
if the Borrower fails to give the Administrative Agent timely notice of its
selection of an Interest Period for any rollover Advance, a one month Interest
Period shall apply.

          (d) Interest Upon Default. Immediately upon the occurrence of an Event
of Default hereunder, the outstanding principal balance of the Loans, together
with accrued and unpaid interest and other unpaid sums, shall bear interest at
the Default Rate. Such interest shall be payable on demand and shall accrue
until the earliest of (a) waiver or cure (to the satisfaction of the Lenders
required under Section 11.12 hereof to waive or cure) of the applicable Event of
Default, or (b) agreement by the Majority Lenders to rescind the charging of
interest at the Default Rate, or (c) payment in full of the Obligations.

          (e) Eurodollar Advances. At no time may the number of outstanding
Eurodollar Advances exceed ten (10), with


                                       31

respect to the Revolving Loan Commitment, or five (5), with respect to either
the Tranche A Term Loan Commitment or the Tranche B Term Loan Commitment.

          (f) Applicable Margin. (i) With respect to any Advance of the Tranche
A Term Loans, or any Advance under the Revolving Loan Commitment, the Applicable
Margin shall be as of any calculation date the interest rate margin determined
by the Administrative Agent based upon the table set forth below (which tests
the Borrower's Leverage Ratio (Total Debt) after the Minimum Contributed Capital
has been raised), determined for the most recent fiscal quarter end, effective
as of the second Business Day after the financial statements referred to in
Section 6.1 hereof are required to be furnished by the Borrower to the
Administrative Agent and each Lender for the fiscal quarter most recently ended
(except with respect to clause (b), which adjustment to the Applicable Margin
shall be effective on the date of receipt by the Borrower of the Investment by
VoiceStream of Minimum Additional Contributed Capital), expressed as a per annum
rate of interest as follows:

without prejudice to any additional rights under Section 8.2 hereof, no downward

Any unpaid principal and interest of the Tranche B Term Loans and any other
outstanding Obligations shall be due and payable in full on the Final Maturity
Date.

     Section 2.5 Fees. (a) Fees Payable Under the Fee Letters. The Borrower
agrees to pay such fees as are mutually agreed upon and as are described in the
Fee Letters.

     (b) Commitment Fee. In addition, the Borrower agrees to pay to the
Administrative Agent, for the benefit of each of the Lenders who have issued a
Revolving Loan Commitment or have agreed to make Tranche A Term Loans, in
accordance with their respective Commitment Ratios for such facilities, a
commitment fee on the aggregate unborrowed balance of the Revolving Loan
Commitment, for each day from the Agreement Date until the Revolving Loan
Maturity Date, and on the aggregate unborrowed amount of the Tranche A Term Loan
Commitment, for each day from the Agreement Date until December 31, 1998, at a
rate of one-half of one percent (1/2%) per annum, provided, however, that for
any period of time in which the Applicable Margin for Eurodollar Advances of the
Revolving Loans shall be 1.50% or less, the commitment fee shall be imposed at a
rate of three-eighths of one percent (3/8%). Such commitment fee shall be
computed on the basis of a year of 365/366 days for the 


                                       35


<PAGE>   37
actual number of days elapsed, shall be payable quarterly in arrears on the last
Business Day of each calendar quarter, commencing September 30, 1998, shall be
fully earned when due, and shall be non-refundable when paid.

     Section 2.6 Prepayments.

     (a) Prepayment of Advances. The principal amount of any Base Rate Advance
may be prepaid in full or in part at any time, without penalty or premium and
without regard to the Payment Date for such Advance, upon not less than three
(3) Business Days' prior written notice to the Administrative Agent of such
prepayment. Eurodollar Advances may be prepaid prior to the applicable Payment
Date, upon not less than three (3) Business Days' prior written notice to the
Administrative Agent, provided that the Borrower shall reimburse the Lenders and
the Administrative Agent, on demand, for any loss or out-of-pocket expense
incurred by any Lender or the Administrative Agent in connection with such
prepayment, as set forth in Section 2.11 hereof.

     (b) Prepayment of Loans. Amounts permanently prepaid on the Revolving Loans
whether by way of refinancing or prepayment of Advances under the Revolving Loan
Commitment accompanied by a corresponding permanent reduction in the Revolving
Loan Commitment shall, unless otherwise specified herein, be applied to interest
and fees then outstanding hereunder on account of Revolving Loans and under the
Revolving Notes, and then to principal. Amounts prepaid on the Term Loans
whether by way of refinancing or prepayment of Advances under the Term Loans
shall, unless otherwise specified herein, be applied to interest then
outstanding hereunder on account of the Term Loans and under the Term Notes, and
then to principal. A notice of prepayment shall be irrevocable. Upon receipt of
any notice of prepayment or reduction, the Administrative Agent shall promptly
notify each Lender of the contents thereof by telephone or telecopy and of such
Lender's portion of the prepayment. Any portion of the Loans which is
permanently prepaid may not be reborrowed. Permanent prepayments of the
Revolving Loans accompanied by a corresponding permanent reduction in the
Revolving Loan Commitment, and prepayments of the Tranche A Term Loans, shall be
applied to the repayment schedule set forth in Section 2.4(a) hereof in inverse
order of maturity. Prepayments of the Tranche B Term Loans shall be applied to
the repayment schedule set forth in Section 2.4(b) hereof in inverse order of
maturity. Partial prepayments shall be in a principal amount of not less than
$5,000,000, and in an integral multiple of $1,000,000. Voluntary permanent


                                       36


<PAGE>   38
prepayments of the Loans shall be applied pro rata to the outstanding Tranche A
Term Loans, the outstanding Tranche B Term Loans and to the Revolving Loan
Commitment.

     Section 2.7 Borrower's Optional Cancellation of the Revolving Loan
Commitment. The Borrower shall have the right, on three (3) Business Days'
irrevocable notice to the Administrative Agent, to cancel all or a portion of
the Revolving Loan Commitment, on a pro rata basis among the Lenders holding
Revolving Loan Commitments, provided that (i) any such cancellation shall be
made in a principal amount of not less than $5,000,000, and in an integral
multiple of $1,000,000; (ii) as of the effective date of such notice, the
Revolving Loan Commitment shall be permanently reduced to the amount stated in
the Borrower's notice for all purposes herein; and (iii) payment shall be made
on or prior to the effective date of such notice of any amount necessary to
reduce the amount of the Revolving Loans outstanding under the Revolving Loan
Commitment to not more than the amount of the Revolving Loan Commitment as
reduced, to be applied as provided in Section 2.6(b), together with any amount
required to be paid by the Borrower under Section 2.11 hereof.

     Section 2.8 Mandatory Prepayments. In addition to the scheduled repayments
provided for in Section 2.4 hereof, the Borrower shall prepay the Loans as
follows:

     (a) Repayment From Excess Cash Flow. On or prior to June 30, 2000, and on
or prior to each June 30th thereafter during the term of this Agreement, the
Borrower shall make an additional prepayment of the outstanding principal amount
of the Loans in an amount equal to fifty percent (50%) of Excess Cash Flow for
the previous fiscal year. Amounts so prepaid shall be applied to the repayment
schedule set forth in Section 2.4(a) and Section 2.4(b) hereof in inverse order
of maturity and shall be applied pro rata to the remaining Revolving Loan
Commitment, the outstanding Tranche A Term Loans, and the outstanding Tranche B
Term Loans. Accrued interest on the principal amount of the Loans being prepaid
pursuant to this Section 2.8(a) to the date of such prepayment will be paid by
the Borrower concurrently with such principal prepayment.

     (b) From Permitted Asset Sales. Net Proceeds from any Permitted Asset Sale
of one or more Core Properties shall be applied, on the Business Day of receipt
thereof by the Borrower or the affected Restricted Subsidiary, as follows:


                                       37


<PAGE>   39
          (i) Except as otherwise permitted in Section 2.8(b)(ii) hereof, to
     permanently prepay the outstanding principal amount of the Loans and
     permanently reduce the Revolving Loan Commitment in order of maturity and
     shall be allocated pro rata among the Revolving Loan Commitment and the
     outstanding principal balance of the Term Loans, provided that such amounts
     prepaid with Net Proceeds and allocated to the Revolving Loan Commitment
     may be reborrowed by the Borrower in an amount not to exceed, in the
     aggregate, the amount of the Revolving Loan Commitment; or

          (ii) At the Borrower's election, so long as no Default then exists or
     would be caused thereby, by the Borrower or any Restricted Subsidiary to
     purchase one or more Allowable Wireless Systems, the aggregate purchase
     price of which does not exceed such Net Proceeds, or the sum of such Net
     Proceeds plus Advances otherwise available for Acquisitions hereunder plus
     other funds available to the Borrower, so long as the Borrower shall have
     (i) entered into a definitive contract for purchase within twelve (12)
     months from the date of such Permitted Asset Sale, and (ii) concluded such
     purchase within eighteen (18) months from the date of such Permitted Asset
     Sale. In the event the Borrower elects to exercise its right under this
     Section 2.8(b)(ii), the Borrower shall so notify the Administrative Agent
     not less than five (5) Business Days prior to the proposed date of the
     closing of the Permitted Asset Sale and shall, upon its or any Restricted
     Subsidiary's receipt of any Net Proceeds with respect to such Permitted
     Asset Sale, remit such Net Proceeds to the Administrative Agent to reduce
     the outstanding principal balance of the Revolving Loans (but not the Term
     Loans nor the amount of the Revolving Loan Commitment). Any amount in
     excess of the then outstanding balance of the Revolving Loans shall be held
     in trust in an interest-bearing account with the Administrative Agent or an
     Affiliate thereof (the "Net Proceeds Trust") for the benefit of the
     Borrower, to be applied to the ultimate purchase of the Allowable Wireless
     System or Systems, as hereinafter provided. Amounts in any Net Proceeds
     Trust shall also be subject to a valid and perfected first priority Lien in
     favor of the Administrative Agent (for itself and for the ratable benefit
     of the Lenders) to secure the Obligations, pursuant to a deposit pledge
     agreement or other security agreement in form and substance reasonably
     satisfactory to the Administrative Agent. The Borrower shall consummate
     such purchase of the 

                                       38


<PAGE>   40
     Allowable Wireless System or Systems not later than eighteen (18) months
     after the date of the applicable Permitted Asset Sale. To the extent that
     the Borrower shall not have entered into a definitive contract for purchase
     within twelve (12) months after the date of the Permitted Asset Sale, or
     consummated any such purchase as of eighteen (18) months after the date of
     such Permitted Asset Sale (for whatever reason, including the occurrence of
     a Default hereunder), or the purchase price of such purchase shall be less
     than the Net Proceeds of the Permitted Asset Sale, any funds held in the
     Net Proceeds Trust relating to such sale shall be applied in the manner set
     forth in Section 2.8(b)(i) hereof.

     Section 2.9 Notes; Loan Accounts.

     (a) The Loans shall be repayable in accordance with the terms and
provisions set forth herein, and shall be evidenced by the Notes. Term Notes
shall be issued by the Borrower and payable to the order of each Lender listed
as making a Tranche A Term Loan or a Tranche B Term Loan on Schedule 1 hereof,
and one Revolving Note shall be issued by the Borrower and payable to the order
of each Lender issuing a Revolving Loan Commitment. The Notes shall be issued by
the Borrower to the Lenders and shall be duly executed and delivered by one or
more Authorized Signatories.

     (b) Each Lender may open and maintain on its books in the name of the
Borrower a loan account with respect to such Lender's portion of the Loans and
interest thereon. Each Lender which opens such a loan account shall debit such
loan account for the principal amount of its portion of each Advance made and
accrued interest thereon and shall credit such loan account for each payment on
account of principal of or interest on its Loan. The records of a Lender with
respect to the loan account maintained by it shall be prima facie evidence of
the Loans and accrued interest thereon, absent manifest error, but the failure
of any Lender to make any such notations or any error or mistake in such
notations shall not affect the Borrower's repayment obligations with respect to
the Loans.

<PAGE>   41
     Section 2.10 Manner of Payment.

     (a) Each payment (including any prepayment) by the Borrower on account of
the principal of or interest on the Loans, commitment fees and any other amount
owed to the Lenders, the Administrative Agent or any of them under this
Agreement or the Notes shall be made not later than 2:00 p.m. (Houston time) on
the date specified for payment under this Agreement to the Administrative Agent
at the Administrative Agent's Office, for the account of the Lenders, or the
Administrative Agent, as the case may be, in lawful money of the United States
of America in immediately available funds. Any payment received by the
Administrative Agent after 2:00 p.m. (Houston time) shall be deemed received on
the next Business Day. Receipt by the Administrative Agent of any payment
hereunder at or prior to 2:00 p.m. (Houston time) on any Business Day shall be
deemed to constitute receipt on such Business Day. In the case of a payment for
the account of a Lender, the Administrative Agent will promptly thereafter (and,
if such amount is received before 2:00 p.m. (Houston time), on the same day)
distribute the amount so received in like funds to such Lender. If the
Administrative Agent shall not have received any payment from the Borrower as
and when due, the Administrative Agent will promptly notify the Lenders
accordingly.

     (b) The Borrower agrees to pay principal, interest, fees and all other
Obligations due hereunder, under the Fee Letters, under the Notes, or under the
other Loan Documents without set-off or counterclaim or any deduction
whatsoever.

     (c) Prior to the acceleration of the Loans under Section 8.2 hereof, if
some but less than all amounts due from the Borrower are received by the
Administrative Agent with respect to the Obligations, the Administrative Agent
shall distribute such amounts in the following order of priority, all on a pro
rata basis to the Lenders: (i) to the payment on a pro rata basis of any fees or
expenses then due and payable to the Administrative Agent, the Lenders, or any
of them; (ii) to the payment of interest then due and payable on the Loans;
(iii) to the payment of all other amounts not otherwise referred to in this
Section 2.10(c) then due and payable to the Administrative Agent or the Lenders,
or any of them, hereunder or under the Notes; and (iv) to the payment of
principal then due and payable on the Notes.

     (d) Subject to any contrary provisions in the definition of Interest
Period, if any payment under this 


                                       40


<PAGE>   42
Agreement or any of the other Loan Documents is specified to be made on a day
which is not a Business Day, it shall be made on the next Business Day, and such
extension of time shall in such case be included in computing interest and fees,
if any, in connection with such payment.

     Section 2.11 Reimbursement.

     (a) Whenever any Lender shall sustain or incur any losses or out-of-pocket
expenses in connection with (i) failure by the Borrower to borrow any Eurodollar
Advance after having given notice of its intention to borrow in accordance with
Section 2.2 hereof (whether by reason of the Borrower's election not to proceed
or the non-fulfillment of any of the conditions set forth in Article 3), (ii)
prepayment of any Eurodollar Advance in whole or in part for any reason, or
(iii) failure by the Borrower to prepay any Eurodollar Advance after giving
notice of its intention to prepay such Advance, the Borrower agrees to pay to
such Lender, upon demand, an amount sufficient to compensate such Lender for all
such losses and reasonable out-of-pocket expenses. Such Lender's good faith
determination of the amount of such losses or out-of-pocket expenses, as set
forth in writing pursuant to Section 2.11(b) hereof, and accompanied by
calculations in reasonable detail demonstrating the basis for its demand, shall
be presumptively correct.

     (b) Losses subject to reimbursement hereunder shall be (i) any loss
incurred by any Lender in connection with the re-employment of funds prepaid,
repaid, not borrowed, or paid, as the case may be, and the amount of such loss
shall be the excess, if any, of (1) the interest or other cost to such Lender of
the deposit or other source of funding used to make any such Eurodollar Advance
for the remainder of its Interest Period, over (2) the interest earned (or to be
earned) by such Lender upon the re-lending or other redeployment of the amount
of such Eurodollar Advance for the remainder of its putative Interest Period or
(ii) any other expenses incurred by any Lender or any participant of such Lender
permitted hereunder in connection with the re-employment of funds prepaid,
repaid, not borrowed, or paid, as the case may be.

     Section 2.12 Pro Rata Treatment.

     (a) Advances. Each Advance of the Revolving Loans, the Tranche A Term Loans
or the Tranche B Term Loans from the Lenders shall be made pro rata on the basis
of the respective Commitment Ratios of the Lenders issuing and 


                                       41


<PAGE>   43
holding Commitments for such Loans, as set forth as of the Agreement Date on
Schedule 1 hereof with respect to the Lenders making Term Loans hereunder.

     (b) Payments. Except as provided in Section 2.2(e)(iv) or Article 10 hereof
or elsewhere in this Agreement, each payment and prepayment of principal of the
Loans, and each payment of interest on the Loans, shall be made to the Lenders
pro rata on the basis of their respective unpaid principal amounts outstanding
immediately prior to such payment or prepayment. If any Lender shall obtain any
payment (whether involuntary, through the exercise of any right of set-off, or
otherwise) on account of the Loans made by it in excess of its ratable share of
the Tranche A Loans, the Tranche B Term Loans, or the Revolving Loans, as the
case may be, such Lender shall forthwith purchase from the other Lenders such
interests (whether by purchasing a participation or by assignment) in the
applicable Loans made by them as shall be necessary to cause such purchasing
Lender to share the excess payment ratably with each of them; provided, however,
that if all or any portion of such excess payment is thereafter recovered from
such purchasing Lender, such purchase from each Lender shall be rescinded and
each such Lender shall repay to the purchasing Lender the purchase price to the
extent of such recovery. The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section 2.12(b) may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of set-off) with respect to such participation as fully as if such
Lender were the direct creditor of the Borrower in the amount of such
participation.

     (c) Delayed Permitted Asset Sale Prepayment. In the event proceeds from a
Permitted Asset Sale are used to reduce the outstanding principal balance of the
Revolving Loans (but not the Revolving Loan Commitment) in accordance with
Section 2.8(b)(ii) hereof and the Borrower fails to enter into a definitive
contract for purchase of an Allowable Wireless System or Systems within twelve
(12) months from the date of the Permitted Asset Sale or the Borrower shall not
have consummated any such purchase as of eighteen (18) months after the date of
such Permitted Asset Sale (for whatever reason, including a Default hereunder),
or the purchase price of such purchase shall be less than the Net Proceeds of
the Permitted Asset Sale, the proceeds of such Permitted Asset Sale, or
applicable portion thereof, shall be reallocated on the date twelve (12) months
or eighteen (18) months after the Permitted Asset Sale (as applicable) on a pro
rata basis in the manner set forth in 


                                       42


<PAGE>   44
Section 2.8(b)(i) hereof as if such proceeds had been used to permanently reduce
the Revolving Loan Commitment and the outstanding principal balance of the Term
Loans upon receipt thereof by the Borrower.

     Section 2.13 Capital Adequacy. If, after the date hereof, the adoption of
any Applicable Law regarding the capital adequacy of banks or bank holding
companies, or any change in Applicable Law (whether adopted before or after the
Agreement Date) or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by such Lender with any
directive issued or adopted after the date hereof regarding capital adequacy
(whether or not having the force of law) of any such governmental authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on any Lender's capital as a consequence of its obligations
hereunder with respect to the Term Loans and the Revolving Loan Commitment to a
level below that which it could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's policies with respect to
capital adequacy immediately before such adoption, change or compliance and
assuming that such Lender's capital was fully utilized prior to such adoption,
change or compliance) by an amount reasonably deemed by such Lender to be
material, then such Lender shall promptly notify the Borrower of such adoption,
compliance, or change. Upon demand by such Lender, the Borrower shall promptly
pay to such Lender such additional amounts as shall be sufficient to compensate
such Lender for such reduced return, together with interest on such amount from
the fourth (4th) day after the date of demand until payment in full thereof at
the Default Rate. A certificate of such Lender setting forth the amount to be
paid to such Lender by the Borrower as a result of any event referred to in this
paragraph and supporting calculations in reasonable detail shall be conclusive,
absent manifest error.

     Section 2.14 Lender Tax Forms. On or prior to the first Payment Date
hereunder and on or prior to the first Business Day of each calendar year
thereafter, each Lender which is organized in a jurisdiction other than the
United States or a political subdivision thereof shall provide each of the
Administrative Agent and the Borrower with either (a) two (2) properly executed
originals of Form 4224 or Form 1001 (or any successor forms) prescribed by the
Internal Revenue Service or other documents satisfactory to the Borrower and the
Administrative Agent, and properly executed 


                                       43


<PAGE>   45
Internal Revenue Service Form W-8 or Form W-9, as the case may be, certifying
(i) as to such Lender's status for purposes of determining exemption from United
States withholding taxes with respect to all payments to be made to such Lender
hereunder and under the Notes or (ii) that all payments to be made to such
Lender hereunder and under the Notes are subject to such taxes at a rate reduced
to zero by an applicable tax treaty, or (b)(i) a certificate executed by such
Lender certifying that such Lender is not a "bank" and that such Lender
qualifies for the portfolio interest exemption under Section 881(c) of the
Internal Revenue Code of 1986, as amended, and (ii) two (2) properly executed
originals of Internal Revenue Service Form W-8 (or any successor form)
prescribed certifying such Lender's entitlement to an exemption from United
States withholding tax with respect to payments of interest to be made under
this Agreement and under any Note. Each such Lender agrees to provide the
Administrative Agent and the Borrower with new forms prescribed by the Internal
Revenue Service upon the expiration or obsolescence of any previously delivered
form, or after the occurrence of any event requiring a change in the most recent
forms delivered by it to the Administrative Agent and the Borrower.

                                    ARTICLE 3

                              Conditions Precedent

     Section 3.1 Conditions Precedent to Initial Advance. The obligation of the
Lenders to make the initial Advance hereunder is subject to the prior
fulfillment of each of the following conditions:

     (a) The Administrative Agent shall have received each of the following
(with sufficient copies for each of the Lenders), in form and substance
satisfactory to the Administrative Agent and each of the Lenders:

          (i) the loan certificate of the Borrower, in substantially the form

                         Representations and Warranties

     Section 4.1 Representations and Warranties. The Borrower hereby agrees,
represents and warrants in favor of the Administrative Agent and each Lender
that:

     (a) Organization; Ownership; Power; Qualification. The Borrower is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation, having VoiceStream as its only
shareholder of record as of the Agreement Date. The Borrower has the corporate
power and authority to own its properties and to carry on its business as now
being and hereafter proposed to be conducted. Each Subsidiary of the Borrower is
a corporation or a partnership duly organized, validly existing and in good
standing under the laws of the state of its incorporation or formation, and has
the corporate or partnership power and authority, as the case may be, to own its
properties and to carry on its business as now being and hereafter proposed to
be conducted. The Borrower and each of its Subsidiaries are duly qualified, in
good standing and authorized to do business in each jurisdiction in which the
character of their respective properties or the nature of their respective
businesses makes such qualification or authorization prudent.

     (b) Authorization; Enforceability. The Borrower has the corporate power and
has taken all necessary action to authorize it to borrow hereunder, to execute,
deliver and perform this Agreement and each of the other Loan Documents to which
it is a party in accordance with their respective terms, and to consummate the
transactions contemplated hereby and thereby. This Agreement has been duly
executed and delivered by the Borrower and is, and each of the other Loan
Documents to which the Borrower is party is, a legal, valid and binding
obligation of the Borrower enforceable against the Borrower in accordance with
its terms, subject, as to enforcement of remedies, to the following
qualifications: (i) an order of specific performance and an 


                                       49


<PAGE>   51
injunction are discretionary remedies and, in particular, may not be available
where damages are considered an adequate remedy at law, (ii) enforcement may be
limited by bankruptcy, insolvency, liquidation, reorganization, reconstruction
and other similar laws affecting enforcement of creditors' rights generally
(insofar as any such law relates to the bankruptcy, insolvency or similar event
of the Borrower), and (iii) enforcement may be subject to general principles of
equity (regardless of whether such enforcement is considered in a proceeding in
equity or at law) and may be limited by public policies which may affect the
enforcement of certain rights or remedies provided for in this Agreement or the
Security Documents.

     (c) Subsidiaries; Authorization; Enforceability. The Borrower's
Subsidiaries (including its Unrestricted Subsidiaries) and Investments and its
direct and indirect ownership thereof are set forth as of the Agreement Date on
Schedule 4 attached hereto, and the Borrower has the unrestricted right to vote
the issued and outstanding shares of the corporate Subsidiaries, and the right
to vote its partnership interests in the partnership Subsidiaries in accordance
with the terms of the applicable partnership agreement, shown thereon; such
shares of such corporate Subsidiaries have been duly authorized and issued and
are fully paid and nonassessable. Each Subsidiary of the Borrower has the
corporate or partnership power and authority, as the case may be, and has taken
all necessary corporate or partnership action to authorize it to execute,
deliver and perform each of the Loan Documents to which it is a party in
accordance with their respective terms and to consummate the transactions
contemplated by this Agreement and by such Loan Documents. Each of the Loan
Documents to which any Subsidiary of the Borrower is party is a legal, valid and
binding obligation of such Subsidiary enforceable against such Subsidiary in
accordance with its terms, subject, as to enforcement of remedies, to the
following qualifications: (i) an order of specific performance and an injunction
are discretionary remedies and, in particular, may not be available where
damages are considered an adequate remedy at law, (ii) enforcement may be
limited by bankruptcy, insolvency, liquidation, reorganization, reconstruction
and other similar laws affecting enforcement of creditors' rights generally
(insofar as any such law relates to the bankruptcy, insolvency or similar event
of such Subsidiary), and (iii) enforcement may be subject to general principles
of equity (regardless of whether such enforcement is considered in a proceeding
in equity or at law) and may be limited by public policies which may affect 


                                       50


<PAGE>   52
the enforcement of certain rights or remedies provided for in such Loan
Documents.

     (d) Compliance with Other Loan Documents and Contemplated Transactions. The
execution, delivery and performance, in accordance with their respective terms,
by the Borrower of this Agreement and the Notes, and by the Borrower and its
Subsidiaries of each of the other Loan Documents to which they are respectively
party, and the consummation of the transactions contemplated hereby and thereby,
do not and will not (i) require any consent or approval, governmental or
otherwise, not already obtained, (ii) violate any Applicable Law respecting the
Borrower or any Subsidiary of the Borrower, (iii) conflict with, result in a
breach of, or constitute a default under the certificate or articles of
incorporation or by-laws, or the partnership agreement, as the case may be, as
such documents are amended, of the Borrower or of any Subsidiary of the
Borrower, or under any material indenture, agreement, or other instrument, to
which the Borrower or any of its Subsidiaries is a party or by which any of them
or their respective properties may be bound, (iv) conflict with, result in a
breach of, or constitute a default or violation of, the terms and conditions of
any of the material Licenses, or (v) result in or require the creation or
imposition of any Lien upon or with respect to any property now owned or
hereafter acquired by the Borrower or any of its Subsidiaries, except for
Permitted Liens.

     (e) Business. The Borrower is a holding company for all its Subsidiaries
and the Borrower, together with its Restricted Subsidiaries, is engaged in the
business of owning, operating, and investing in PCS Systems or otherwise
providing wireless communications or telecommunications services and in related
business activities.

     (f) Licenses, Etc. The Licenses, as well as the Licenses held by
Unrestricted Subsidiaries, have been duly authorized by the grantors thereof and
are in full force and effect. The Borrower and its Subsidiaries are in
compliance in all material respects with all of the provisions thereof. Except
as set forth on Schedule 5 attached hereto, the Borrower and its Subsidiaries
have secured all material Licenses and Necessary Authorizations and all such
material Licenses and Necessary Authorizations are in full force and effect.
Except as set forth on Schedule 5 attached hereto, neither any material License
nor any material Necessary Authorization is the subject of any pending or, to
the best of the Borrower's knowledge, threatened revocation. For purposes of
this Section 4.1(f), "Licenses" shall mean and 


                                       51


<PAGE>   53
include Licenses of Unrestricted Subsidiaries, each of which shall be listed as
of the Agreement Date on Schedule 2 attached hereto.

     (g) Compliance with Law. The Borrower and its Subsidiaries are in
substantial compliance with all material Applicable Law.

     (h) Title to Assets. The Borrower has good, legal and marketable title to,
or a valid leasehold interest in, all of its assets. Each of the Borrower's
Subsidiaries has good, legal and marketable title to, or a valid leasehold
interest in, all of its assets. None of such properties or assets held by the
Borrower or any of its Restricted Subsidiaries is subject to any Liens, except
for Permitted Liens, and for financing statements securing the Nortel Debt for
which duly executed terminations have been presented as of the Agreement Date.
Except for financing statements evidencing Permitted Liens, or financing
statements securing the Nortel Debt for which duly executed terminations have
been presented as of the Agreement Date, no financing statement under the
Uniform Commercial Code as in effect in any jurisdiction and no other filing
which names the Borrower or any of its Restricted Subsidiaries as debtor or
which covers or purports to cover any of the assets of the Borrower or any of
its Restricted Subsidiaries is currently effective and on file in any state or
other jurisdiction, and neither the Borrower nor any of its Restricted
Subsidiaries has signed any such financing statement or filing or any security
agreement authorizing any secured party thereunder to file any such financing
statement or filing.

     (i) Litigation. There is no action, suit, revocation, proceeding or
investigation pending against, or, to the best of the Borrower's knowledge,
threatened against or in any other manner relating adversely to, the Borrower or
any of its Subsidiaries or any of their respective properties, including without
limitation any License or Necessary Authorization, in any court or before any
arbitrator of any kind or before or by any governmental body (including without
limitation the FCC), except as described on Schedule 6 attached hereto as of the
Agreement Date or as subsequently disclosed to the Administrative Agent and the
Lenders pursuant to Section 6.5 hereof; and, except as expressly set forth on
Schedule 6 (or if disclosed pursuant to Section 6.5), no such action, suit,
proceeding or investigation could reasonably be expected to have an adverse
outcome which (i) calls into question the validity of this Agreement or any
other Loan Document, (ii) 


                                       52


<PAGE>   54
challenges the continued possession and use of any License granted by the FCC,
by the Borrower, any of its Subsidiaries, or any Person in which the Borrower
has, directly or indirectly, an Investment and such challenge could result in a
Default pursuant to Section 8.1(l) or Section 8.1(m) hereof, or (iii) could have
a Materially Adverse Effect.

     (j) Taxes. All federal, state and other tax returns (including information
returns) of the Borrower and each of its Subsidiaries required by law to be
filed have been duly filed and all federal, state and other taxes, including,
without limitation, withholding taxes, assessments and other governmental
charges or levies required to be paid by the Borrower or any of its Subsidiaries
or imposed upon the Borrower or any of its Subsidiaries or any of their
respective properties, income, profits or assets, which are due and payable,
have been paid, except any such taxes (i) the payment of which the Borrower or
any of its Subsidiaries is diligently contesting in good faith by appropriate
proceedings, (ii) for which adequate reserves have been provided on the books of
the Borrower or the Subsidiary of the Borrower involved, and (iii) as to which
no Lien other than a Permitted Lien has attached and no foreclosure, distraint,
sale or similar proceedings have been commenced. The charges, accruals and
reserves on the books of the Borrower and each of its Subsidiaries in respect of
taxes are, in the judgment of the Borrower, adequate.

     (k) Financial Statements. The Borrower has furnished or caused to be
furnished to the Administrative Agent and the Lenders its unaudited balance
sheet dated the Agreement Date, audited financial statements on a consolidated
basis for VoiceStream and its Subsidiaries for the fiscal year ended December
31, 1997, which, together with other financial statements furnished to the
Administrative Agent and the Lenders subsequent to the Agreement Date, are
complete and correct in all material respects and present fairly in accordance
with GAAP the financial position of the Borrower and its Subsidiaries on a
consolidated basis on and as at such dates and the results of operations for the
periods then ended. Except as provided on Schedule 7 attached hereto, neither
the Borrower nor any of its Subsidiaries has any material liabilities,
contingent or otherwise, other than as disclosed in the financial statements
referred to in the preceding sentence or as set forth or referred to in this
Agreement, and there are no material unrealized losses of the Borrower or any of
its Subsidiaries and no anticipated losses of the Borrower or any of its
Subsidiaries other than those which have been 


                                       53


<PAGE>   55
disclosed in writing to the Administrative Agent and the Lenders prior to the
Agreement Date and identified as such.

     (l) No Adverse Change. Since December 31, 1997, there has occurred no event
which has had or which could have a Materially Adverse Effect.

     (m) ERISA. The Borrower and each Subsidiary of the Borrower and each of
their respective Plans are in compliance in all material respects with ERISA and
the Code and neither the Borrower nor any of its Subsidiaries has incurred any
accumulated funding deficiency with respect to any such Plan within the meaning
of ERISA or the Code. The Borrower, each of its Subsidiaries, and each other
ERISA Affiliate have complied with all requirements of Sections 10001 and 10002
of the Consolidated Omnibus Budget Reconciliation Act of 1985 (Public Law No.
99-272), Section 4980B of the Internal Revenue Code. Neither the Borrower nor
any of its Subsidiaries has made any promises of retirement or other benefits to
employees, except as set forth in their respective Plans, in written agreements
with such employees, or in the Borrower's employee handbook and memoranda to
employees. Neither the Borrower nor any of its Subsidiaries has incurred any
material liability to PBGC in connection with any such Plan. The assets of each
such Plan subject to Title IV of ERISA are sufficient to provide the benefits
under such Plan. Such assets are also sufficient to provide all other "benefit
liabilities" (as defined in Section 9313(a) of the Pension Protection Act
included in the Omnibus Budget Reconciliation Act of 1987, Pub. L-100-203),
Section 4001A(16) of ERISA, due under the Plan upon termination. No Reportable
Event has occurred and is continuing with respect to any such Plan. No such Plan
or trust created thereunder, or party in interest (as defined in Section 3(14)
of ERISA), or any fiduciary (as defined in Section 3(21) of ERISA), has engaged
in a "prohibited transaction" (as such term is defined in Section 406 of ERISA
or Section 4975 of the Code) which would subject such Plan or any other Plan of
the Borrower or any of its Subsidiaries, any trust created thereunder, or any
such party in interest or fiduciary, or any party dealing with any such Plan or
any such trust, to the tax or penalty in any material amount on "prohibited
transactions" imposed by Section 502 of ERISA or Section 4975 of the Code.
Neither the Borrower nor any of its Subsidiaries is a participant in or is
obligated to make any payment to a Multiemployer Plan. Neither the Borrower nor
any of its Subsidiaries (1) has had either a complete withdrawal or a partial
withdrawal under Section 4201 et. seq. of ERISA from a Multiemployer Plan which
had "unfunded vested benefits" within the meaning of 


                                       54


<PAGE>   56
Section 4211 of ERISA or (2) has ever received a notice and demand from the plan
sponsor of a Multiemployer Plan under Section 4219(b)(1) of ERISA.

     (n) Compliance with Regulations G, T, U, and X. Neither the Borrower nor
any Subsidiary of the Borrower is engaged principally in or has as one of its
important activities the business of purchasing or carrying, or extending credit
for the purpose of purchasing or carrying, any margin stock within the meaning
of Regulations G, T, U, and X of the Board of Governors of the Federal Reserve
System; nor will any proceeds of the Loans be used for such purpose.

     (o) Investment Company Act. Neither the Borrower nor any of its
Subsidiaries is required to register under the provisions of the Investment
Company Act of 1940, as amended, and neither the entering into or performance by
the Borrower and its Subsidiaries of this Agreement nor the issuance of the
Notes violates any provision of such Act or requires any consent, approval or
authorization of, or registration with, the Securities and Exchange Commission
or any other governmental or public body or authority pursuant to any provisions
of such Act.

     (p) Governmental Regulation. Neither the Borrower nor any of its
Subsidiaries is required to obtain any consent, approval, authorization, permit
or license which has not already been obtained from, or effect any filing or
registration which has not already been effected with, any federal, state or
local regulatory authority in connection with the execution and delivery of this
Agreement. Neither the Borrower nor any of its Subsidiaries is required to
obtain any consent, approval, authorization, permit or license which has not
already been obtained from, or effect any filing or registration which has not
already been effected with, any federal, state or local regulatory authority in
connection with the performance, in accordance with their respective terms, of
this Agreement or any other Loan Document.

     (q) Absence of Default, Etc. The Borrower and its Subsidiaries are in
compliance in all respects with all of the provisions of their respective
certificates or articles of incorporation and by-laws, or their partnership
agreements, as the case may be, and no event has occurred or failed to occur
(including, without limitation, any matter which could create a Default
hereunder by cross-default) which has not been remedied or waived, the
occurrence or non-occurrence of which constitutes, or with the passage of 


                                       55


<PAGE>   57
time or giving of notice or both would constitute, (i) an Event of Default or
(ii) a material default by the Borrower or any of its Subsidiaries under any
indenture, agreement or other instrument relating to Indebtedness of the
Borrower or any of its Subsidiaries in the amount of $1,000,000 or more, any
License, or any judgment, decree or order in the amount of $1,000,000 or more to
which the Borrower or any of its Subsidiaries is a party or by which the
Borrower or any of its Subsidiaries or any of their respective properties may be
bound or affected. Neither the Borrower nor any of its Subsidiaries is a party
to or bound by any contract or agreement continuing after the Agreement Date, or
bound by any Applicable Law, that could have a Materially Adverse Effect or
result in the loss of any License issued by the FCC.

     (r) Accuracy and Completeness of Information. All information, reports,
prospectuses and other papers and data relating to the Borrower or any of its
Subsidiaries and furnished by or on behalf of the Borrower or any of its
Subsidiaries to the Administrative Agent or the Lenders were, at the time
furnished, true, complete and correct in all material respects to the extent
necessary to give the Administrative Agent and the Lenders true and accurate
knowledge of the subject matter. No fact or situation is currently known to the
Borrower which has had or could have a Materially Adverse Effect other than any
fact or situation known to and affecting the cellular telephone, PCS or
telecommunications industry generally.

     (s) Agreements with Affiliates and Management Agreements. Except as set
forth on Schedule 8 attached hereto, neither the Borrower nor any of its
Subsidiaries has (i) to the best of its knowledge, any written agreements or
binding arrangements of any kind with any Affiliate or (ii) any material
management or consulting agreements of any kind, not entered into in the
ordinary course of business.

     (t) Payment of Wages. The Borrower and each of its Subsidiaries are in
compliance with the Fair Labor Standards Act, as amended, in all material
respects, and the Borrower and each of its Subsidiaries have paid all minimum
and overtime wages required by law to be paid to their respective employees.

     (u) Priority. The Security Interest is a valid and perfected first priority
security interest in the Collateral in favor of the Administrative Agent, for
itself and for the ratable benefit of the Lenders, securing, in accordance with
the terms of the Security Documents, the outstanding 


                                       56

Obligations, and the Collateral is subject to no Liens other than Permitted
Liens. The Liens created by the Security Documents are enforceable as security
for the outstanding Obligations in accordance with their terms with respect to
the Collateral subject, as to enforcement of remedies, to the following
qualifications: (i) an order of specific performance and an injunction are
discretionary remedies and, in particular, may not be available where damages
are considered an adequate remedy at law, (ii) enforcement may be limited by
bankruptcy, insolvency, liquidation, reorganization, reconstruction and other
similar laws affecting enforcement of creditors' rights generally (insofar as
any such law relates to the bankruptcy, insolvency or similar event of the
Borrower or any of its Restricted Subsidiaries, as the case may be), and (iii)
enforcement may be subject to general principles of equity (regardless of
whether such enforcement is considered in a proceeding in equity or at law) and
may be limited by public policies which may affect the enforcement of certain
rights or remedies provided for in such Loan Documents.

     (v) Indebtedness. Except as permitted pursuant to Section 7.1 hereof,
neither the Borrower nor any of its Restricted Subsidiaries has outstanding, as
of the Agreement Date, and after giving effect to the initial Advance hereunder
on the Agreement Date, any Indebtedness for Money Borrowed.

     (w) Investments. All Investments of the Borrower and its Subsidiaries are
shown as of the Agreement Date on Schedule 4 attached hereto.

real property, and (ii) no single parcel of such real estate has a fair market
value on the Agreement Date in excess of $500,000.

     (y) Year 2000 Problem. The Borrower has (i) initiated a review and
assessment of all areas within its and each of its Subsidiaries' business and
operations (including those affected by suppliers, vendors and customers) that
could be adversely affected by the "Year 2000 Problem" (that is, the risk that
computer applications used by the Borrower or any of its Subsidiaries (or
suppliers, vendors and customers) may be unable to recognize and perform
properly date-sensitive functions involving certain dates prior to and any date
after December 31, 1999), (ii) developed a plan and timeline for addressing the
Year 2000 Problem on a timely basis, and (iii) to date, implemented that plan in


                                       57


<PAGE>   59
accordance with that timetable. Based on the foregoing, the Borrower believes
that all computer applications (including those of its suppliers, vendors and
customers) that are material to its or any of its Subsidiaries' business and
operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates before and after January 1,
2000.

     (z) Intellectual Property. The Borrower and its Restricted Subsidiaries
own, possess or have the right to use all material licenses and rights to all
patents, trademarks, trademark rights, trade names, trade name rights, service
marks and copyrights necessary to conduct their business in all material
respects as now conducted, without known conflict with any patent, trademark,
trade name, service mark, license or copyright of any other Person, and such
intellectual property of the Borrower and its Restricted Subsidiaries is subject
to no Lien, other than any Permitted Liens. All such licenses and rights with
respect to patents, trademarks, trademark rights, trade names, trade name
rights, service marks and copyrights are in full force and effect in all
material respects, and are not subject to any pending or, to the best knowledge
of the Borrower, threatened attack or revocation.

     Section 4.2 Survival of Representations and Warranties, etc. All
representations and warranties made under this Agreement and the other Loan
Documents shall be deemed to be made, and shall be true and correct, at and as
of the Agreement Date and on the date of each Advance except to the extent
expressly applicable only to the Agreement Date or previously fulfilled in

this Agreement shall survive, and not be waived by, the execution hereof by the
Lenders and the Administrative Agent, any investigation or inquiry by any Lender
or the Administrative Agent, or the making of any Advance under this Agreement.

and by the Person designated in such written notice of transfer, in form and
substance satisfactory to the Administrative Agent, shall have been filed with

entitled to assume that no Default has occurred and is continuing unless it has
actual knowledge, or has been notified by the Borrower, of such fact, or has
been notified by a Lender in writing that such Lender considers that a Default
has occurred and is continuing, and such Lender shall specify in detail the
nature thereof in writing. The Administrative Agent shall not be liable

respect to exercising or refraining from exercising any rights which may be
vested in it by, and with respect to taking or refraining from taking any action
or actions which it may be able to take under or in respect of, this Agreement,
unless the Administrative Agent shall have been instructed by the Majority

from taking such action; provided that the Administrative Agent shall not
exercise any rights under Section 8.2(a) of this Agreement except upon the
request of the Majority Lenders or of all the Lenders, where expressly required
by this Agreement. The Administrative Agent shall incur no liability under or in
respect of this Agreement with respect to anything which it may do or refrain
from doing in the reasonable exercise of its judgment or which may seem to it to
be necessary or desirable in the circumstances for the protection of the
interests of the Lenders, except for its gross negligence or willful misconduct,
or conduct in breach 


                                       87

action or to assert rights under this Agreement in respect of any Default within
ten (10) days after their receipt of the notice of any Default from the
Administrative Agent or any Lender, or shall request inconsistent action with
respect to such Default, the Administrative Agent may, but shall not be required
to, take such action and assert such rights (other than rights under Article 8
hereof) as it deems in its discretion to be advisable for the protection of the
Lenders, except that, if the Majority Lenders have instructed the Administrative
Agent not to take such action or assert such right, in no event shall the
Administrative Agent act contrary to such instructions.

Administrative Agent (to the extent not reimbursed by the Borrower) pro rata
according to their percentage of the outstanding principal amount of the Loans
and their Commitments from and against any and all liabilities, obligations,
losses (other than in the event of a bankruptcy or out-of-court 'work-out' of
the Loans), damages, penalties, actions, judgments, suits, costs, expenses
(including reasonable fees and expenses of experts, agents, consultants and
counsel), or 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 its role as Administrative Agent under this Agreement, any
other Loan Document, or any other document contemplated by this Agreement or any
action taken or omitted by the Administrative Agent under this Agreement, any
other Loan Document, or any other document contemplated by this Agreement in its
role as Administrative Agent, except that no Lender shall be liable to the

Agent as determined by a final, non-appealable order of a court having
jurisdiction over the subject matter.

Subsidiaries and that it has made an independent credit 


                                       89


<PAGE>   91
judgment, and that it has not relied upon the Administrative Agent, any Managing
Agent, or any other Lender, or information provided by the Administrative Agent
(other than information provided to the Administrative Agent by the Borrower and
forwarded by the Administrative Agent to the Lenders); and

     (b) So long as any portion of the Obligations remains outstanding, it will
continue to make its own independent evaluation of the financial condition and
affairs of the Borrower.

     (a) Resignation. Subject to the appointment and acceptance of a successor
Administrative Agent as provided below, the Administrative Agent may resign at
any time by giving written notice thereof to the Lenders and the Borrower. Upon
any such resignation, the Majority Lenders shall have the right to appoint a
successor Administrative Agent. If no successor Administrative Agent shall have
been so appointed by the Majority Lenders and shall have accepted such
appointment within thirty (30) days after the retiring Administrative Agent
gives notice of resignation, then the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor Administrative Agent which shall be
any Lender or a commercial bank organized under the laws of the United States of
America or any political subdivision thereof which has combined capital and
reserves in excess of $250,000,000. Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges, duties and obligations of the retiring
Administrative Agent and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder. After any retiring Administrative
Agent's resignation hereunder as Administrative Agent, the provisions of this
Article shall continue in effect for its benefit in respect of any actions taken
or omitted to be taken by it while it was acting as the Administrative Agent.
The resignation of the Administrative Agent may not take effect until a
successor Administrative Agent is appointed.

Agent hereunder at any time by written notice given to it by Lenders holding not
less than sixty-six and two-thirds percent (66-2/3%) of the sum of the Revolving
Loan Commitment plus outstanding principal balance of the Term Loans. Upon any
such removal, such Lenders 


                                       90


<PAGE>   92
shall have the right to appoint a successor Administrative Agent, subject, at
any such time as there is no Default hereunder, to the prior written consent of
the Borrower, such consent not to be unreasonably withheld or delayed. Any such
successor Administrative Agent may be any Lender or a commercial bank organized
under the laws of the United States of America or any political subdivision
thereof which has combined capital and reserves in excess of $250,000,000. Upon
the acceptance of any appointment as Administrative Agent hereunder by a
successor Administrative Agent, such successor Administrative Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges,
duties and obligations of the retiring Administrative Agent and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder. After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Article shall continue in effect
for its benefit in respect of any actions taken or to be taken by it while it
was acting as the Administrative Agent.

the facing page of, signature pages of or elsewhere in this Agreement as a
"co-agent" or "managing agent" shall have any right, power, obligation,
liability, responsibility or duty under this Agreement or any other Loan
Document other than those applicable to all Lenders as such. Without limiting
the foregoing, none of the Lenders so identified shall have or be deemed to have
any fiduciary relationship with any other Lender. Each Lender acknowledges that
it has not relied, and will not rely, on any of the Lenders so identified in
deciding to enter into this Agreement or any other Loan Document or in taking or
not taking action hereunder or thereunder.

any affected Lender to make Eurodollar Advances shall be suspended.

     Section 10.2 Illegality. If after the date hereof, the adoption of any
Applicable Law, or any change in any Applicable Law (whether adopted before or
after the Agreement Date), or any change in interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by any Lender
with any directive (whether or not having the force of law) of any such
authority, central bank or comparable agency, shall make it unlawful or
impossible for any Lender to make, maintain or fund Eurodollar Advances, such
Lender shall so notify the Administrative Agent, and the Administrative Agent
shall forthwith give notice thereof to the other Lenders and the Borrower.
Before giving any notice to the Administrative Agent pursuant to this Section
10.2, such Lender shall designate a different lending office if such designation
will avoid the need for giving such notice and will not, in the sole judgment of
such Lender, be otherwise materially disadvantageous to such Lender. Upon
receipt of such notice, notwithstanding anything contained in Article 2 hereof,
the Borrower shall repay in full the then outstanding principal amount of each
Eurodollar Advance of such Lender, together with accrued interest thereon and
any reimbursement required under Section 2.11 hereof, on either (a) the last day
of the then current Interest Period applicable to such affected Eurodollar
Advances if such Lender may lawfully continue to maintain and fund such
Eurodollar Advances to such day or (b) immediately if such Lender may not
lawfully continue to fund and maintain such affected Eurodollar Advances to such
day. Concurrently with repaying each affected Eurodollar Advance of such Lender,
notwithstanding anything contained in Article 2 or Article 3


                                       92


<PAGE>   94
hereof, the Borrower may borrow a Base Rate Advance from such Lender, and such
Lender shall make such Advance, if so requested, in an amount such that the
outstanding principal amount of the Note held by such Lender shall equal the
outstanding principal amount of such Note immediately prior to such repayment.

     Section 10.3 Increased Costs.

     (a) If after the date hereof, the adoption of any Applicable Law, or any
change in any Applicable Law (whether adopted before or after the Agreement
Date), or any interpretation or change in interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof or compliance by any Lender
with any directive (whether or not having the force of law) of any such
authority, central bank or comparable agency:

          (1) shall subject any Lender to any tax, duty or other charge with
     respect to its obligation to make Eurodollar Advances, or shall change the
     basis of taxation of payments to any Lender of the principal of or interest
     on its Eurodollar Advances or in respect of any other amounts due under
     this Agreement, in respect of its Eurodollar Advances or its obligation to
     make Eurodollar Advances (except for changes in the rate or method of
     calculation of tax on the overall net income of such Lender); or

          (2) shall impose, modify or deem applicable any reserve (including,
     without limitation, any imposed by the Board of Governors of the Federal
     Reserve System, but excluding any included in an applicable Eurodollar
     Reserve Percentage or Domestic Reserve Percentage), special deposit,
     capital adequacy, assessment or other requirement or condition against
     assets of, deposits with or for the account of, or commitments or credit
     extended by, any Lender or shall impose on any Lender or the London
     interbank borrowing market or the New York certificate of deposit market
     any other condition affecting its obligation to make Eurodollar Advances or
     its Eurodollar Advances;

and the result of any of the foregoing is to increase the cost to such Lender of
making or maintaining any such Eurodollar Advances, or to reduce the amount of
any sum received or receivable by such Lender under this Agreement or under its
Note with respect thereto, then, within five (5) days after demand by such
Lender, the Borrower agrees to 


                                       93


<PAGE>   95
pay to such Lender such additional amount or amounts as will compensate such
Lender for such increased costs. Each Lender will promptly notify the Borrower
and the Administrative Agent of any event of which it has knowledge, occurring
after the date hereof, which will entitle such Lender to compensation pursuant
to this Section 10.3 and will designate a different lending office if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the sole judgment of such Lender, be otherwise disadvantageous
to such Lender.

     (b) Any Lender claiming compensation under this Section 10.3 shall provide
the Borrower with a written certificate setting forth the additional amount or
amounts to be paid to it hereunder and calculations therefor in reasonable
detail. Such certificate shall be presumptively correct, absent manifest error.
In determining such amount, such Lender may use any reasonable averaging and
attribution methods. If any Lender demands compensation under this Section 10.3,
the Borrower may at any time, upon at least five (5) Business Days' prior notice
to such Lender, prepay in full the then outstanding Eurodollar Advances of such
Lender, together with accrued interest thereon to the date of prepayment, along
with any reimbursement required under Section 2.11 hereof. Concurrently with
prepaying such Eurodollar Advances, the Borrower may borrow a Base Rate Advance
from such Lender, and such Lender shall, if so requested, make such Advance in
an amount such that the outstanding principal amount of the Note held by such
Lender shall equal the outstanding principal amount of such Note immediately
prior to such prepayment.

     Section 10.4 Effect On Other Advances. If notice has been given pursuant to
Section 10.1, 10.2 or 10.3 suspending the obligation of any Lender to make
Eurodollar Advances, or requiring Eurodollar Advances of any Lender to be repaid
or prepaid, then, unless and until such Lender notifies the Borrower that the
circumstances giving rise to such repayment no longer apply, all Advances which
would otherwise be made by such Lender as Eurodollar Advances affected shall, at
the option of the Borrower, be made instead as Base Rate Advances or the
unaffected type of Eurodollar Advances.

     (a) all reasonable out-of-pocket expenses of the Administrative Agent in
connection with the preparation, negotiation, execution and delivery of this
Agreement and the other Loan Documents, and the transactions contemplated
hereunder and thereunder and the making of the initial Advance hereunder
(whether or not such Advance is made), including, but not limited to, the fees
and disbursements of Paul, Hastings, Janofsky & Walker LLP, special counsel for
the Administrative Agent and its Affiliates;

     (b) all reasonable out-of-pocket expenses of the Administrative Agent in
connection with the administration of the transactions contemplated in this
Agreement or the other Loan Documents, the restructuring and "work out" of such
transactions, and the preparation, negotiation, execution and delivery of any
waiver, amendment or consent by the Administrative Agent and the Lenders
relating to this Agreement or the other Loan Documents, including, but not
limited to, the fees and disbursements of any experts, 


                                       96


<PAGE>   98
agents or consultants and of special counsel for the Administrative Agent, but
excluding any assignment fee pursuant to Section 11.5(b) hereof; and

     (c) all out-of-pocket costs and expenses of obtaining performance under

expenses of special counsel for the Administrative Agent.

     Section 11.3 Waivers. The rights and remedies of the Administrative Agent
and the Lenders under this Agreement and the other Loan Documents shall be
cumulative and not exclusive of any rights or remedies which they would
otherwise have. No failure or delay by the Administrative Agent or the Lenders,
or any of them, in exercising any right, shall operate as a waiver of such
right. The Administrative Agent and the Lenders expressly reserve the right to
require strict compliance with the terms of this Agreement in connection with
any future funding of a request for an Advance. In the event the Lenders decide
to fund an Advance at a time when the Borrower is not in strict compliance with
the terms of this Agreement, such decision by the Lenders shall not be deemed to
constitute an undertaking by the Lenders to fund any further Advances or
preclude the Lenders and the Administrative Agent from exercising any rights
available under the Loan Documents or at law or equity. Any waiver or indulgence
granted by the Administrative Agent, the Lenders or the Majority Lenders shall
not constitute a modification of this Agreement, except to the extent expressly
provided in such waiver or indulgence, or constitute a course of dealing at
variance with the terms of this Agreement such as to require further notice of
their intent to require strict adherence to the terms of this Agreement in the
future.

     Section 11.4 Set-Off. In addition to any rights now or hereafter granted
under Applicable Law and not by way of limitation of any such rights, upon the
occurrence of an Event of Default and during the continuation thereof, the
Administrative Agent and the Lenders are hereby authorized by the Borrower at
any time or from time to time, without notice to the Borrower or to any other
Person, any such notice being hereby expressly waived, to set off and to
appropriate and to apply any and all deposits (general or special, time or
demand, including, but not limited to, Indebtedness evidenced by certificates of
deposit, in each case whether matured or unmatured) and any other Indebtedness
at any time held or owing by any Lender or the 


                                       97


<PAGE>   99
Administrative Agent to or for the credit or the account of the Borrower or any
of its Restricted Subsidiaries against and on account of the Obligations
irrespective of whether (a) any Lender or the Administrative Agent shall have
made any demand hereunder or (b) the Administrative Agent shall have declared
the principal of and interest on the Loans and other amounts due hereunder to be
due and payable as permitted by Section 8.2 and although such Obligations or any
of them, shall be contingent or unmatured. Upon direction by the Administrative
Agent with the consent of the Majority Lenders, each Lender holding deposits of
the Borrower or any of its Restricted Subsidiaries shall exercise its set-off
rights as so directed.

     Section 11.5 Assignment.

     (a) The Borrower may not assign or transfer any of its rights or
obligations hereunder without the prior written consent of each of the Lenders.

     (b) Each Lender may enter freely into participation agreements with respect
to or otherwise grant participations in its Loans to one or more banks or other
lenders or financial institutions; provided, however, that (i) such Lender's
obligations hereunder shall remain unchanged, (ii) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (iii) the participant shall not be entitled by the benefit of its
participation to vote or otherwise take action under this Agreement or any other
Loan Document, except with respect to the matters referred to in items (a), (b),
(c), (d), (e), (f) and (g) of Section 11.12 hereof, and (iv) the Borrower
(unless there exists at the time of such participation an Event of Default
hereunder) shall have the right to consent to a proposed participant (such
consent not to be unreasonably withheld or delayed) and shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations hereunder. In addition, each Lender may (x) sell or assign up to one
hundred percent (100%) of its rights hereunder and under the other Loan
Documents to any Federal Reserve Bank without limitation; and (y) sell or assign
up to one hundred percent (100%) of its rights hereunder and under the other
Loan Documents to any other Person on an assignment basis, provided that (A) (i)
such assignment is to an Affiliate of the assignor, an Approved Fund, another
Lender, or any Person shown as of the Agreement Date on Schedule 1 as an
Approved Fund, or (ii) the Borrower (unless there exists at the time of such
assignment an Event of Default hereunder) and the Administrative Agent have
given their prior written 


                                       98


<PAGE>   100
consent to the proposed assignee of a Lender hereunder, which consents shall not
be unreasonably delayed or withheld, provided that such consents may be
reasonably withheld if the proposed assignee is subject to withholding tax of
the sort referred to in Section 2.14 hereof, (B) the assignee assumes a pro rata
share of the assignor Lender's obligations hereunder determined by the
percentage of the Revolving Loan Commitment or the appropriate Term Loan
assigned, as applicable, for the period from the date of the assignment through
the Revolving Loan Maturity Date with respect to an assignment of a Revolving
Loan Commitment or a Tranche A Term Loan, or the Final Maturity Date with
respect to an assignment of a Tranche B Term Loan, and (C) each such assignment
shall be in a principal amount of not less than the lesser of the entire amount
of such Lender's interest hereunder or $5,000,000, unless an assignment is from
one Lender to another, or to an Affiliate of another Lender, or to an Approved
Fund, in which case there shall be no minimum assignment amount. Each Lender who
sells or assigns a portion of its Loans pursuant hereto shall pay to the
Administrative Agent an assignment fee of $3,500 with respect to each
assignment, such fee to be paid to the Administrative Agent not later than the
effective date of the assignment of the Loan relating thereto; provided however,
that no such fee shall be payable in the case of an assignment to another
Lender, an Affiliate of a Lender or an Approved Fund; and provided, further
that, in the case of contemporaneous assignments by a Lender to more than one
fund managed by the same investment advisor (which funds are not then Lenders
hereunder), only a single such $3,500 fee shall be payable for all such
contemporaneous assignments. Each Lender agrees to provide the Administrative
Agent, the Arranging Agents, and the Borrower with written notice of the
assignment of all or part of its rights hereunder, and the Administrative Agent
shall keep a record of all such assignments in order to be able to calculate the
Commitment Ratios of the Lenders as of any time. All assignments by any of the
Lenders of any interests hereunder shall be made pursuant to an Assignment and
Assumption Agreement substantially in the form attached hereto as Exhibit R.
Each Lender may provide any proposed participant or assignee with confidential
information provided to such Lender regarding the Borrower and its Subsidiaries
on a confidential basis, and such participant or assignee shall agree to
maintain such confidentiality. Further, each permitted assignee of any portion
of the Loans shall be entitled to the benefits of Sections 2.11 and 2.13 and
Article 10 hereof and all other provisions hereof and of the other Loan
Documents as a 'Lender' hereunder.

     (c) Except as specifically set forth in Section 11.5(b) hereof, nothing in
this Agreement or the Notes, expressed or implied, is intended to or shall
confer on any Person other than the respective parties hereto and thereto and
their successors and assignees permitted hereunder and thereunder any benefit or
any legal or equitable right, remedy or other claim under this Agreement or the
Notes.

     (d) The provisions of this Section 11.5 shall not apply to any purchase of
participations among the Lenders pursuant to Section 2.12 hereof.

     Section 11.6 Accounting Principles.

     (a) Except as set forth in the following sentence, references in this
Agreement to GAAP shall be to such principles as in effect from time to time,
and all accounting terms used herein without definition shall be used as defined
under GAAP. All references to Operating Cash Flow, Total Debt, Fixed Charges,
Debt Service, and other such terms shall be deemed to refer to such items of the
Borrower and its Restricted Subsidiaries on a consolidated basis, consistently
applied, unless otherwise indicated herein.

     (b) With respect to any determination of whether the Borrower shall be
permitted to make an Investment, Acquisition, Restricted Payment, or the like,
which determination depends upon whether the Borrower's aggregate amount of such
aforementioned items equals or exceeds a sum, one of whose constituents is
Available Equity or proceeds of Subordinated Debt, the Available Equity or
proceeds of Subordinated Debt used for such determination may not be
double-counted.

     Section 11.7 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument.

     Section 11.8 Governing Law. This Agreement and the Notes shall be construed
in accordance with and governed by the internal laws of the State of New York
applicable to agreements made and to be performed in New York. If any action or
proceeding shall be brought by the Administrative Agent or any Lender in order
to enforce any right or remedy under this Agreement or under any Note, the
Borrower hereby consents and will, and the Borrower will cause each 


                                      100


<PAGE>   102
Subsidiary to, submit to the jurisdiction of any state or federal court of
competent jurisdiction sitting within the area comprising the Southern District
of New York on the date of this Agreement. The Borrower, for itself and on
behalf of its Subsidiaries, hereby agrees that service of the summons and
complaint and all other process which may be served in any such suit, action or
proceeding may be effected by mailing by registered mail a copy of such process
to the offices of the Borrower at the address given in Section 11.1 hereof and
that personal service of process shall not be required. Nothing herein shall be
construed to prohibit service of process by any other method permitted by law or
the bringing of any suit, action or proceeding in any other jurisdiction. The
Borrower agrees that final judgment in such suit, action or proceeding shall be
conclusive and may be enforced in any other jurisdiction by suit on the judgment
or in any other manner provided by Applicable Law.

     Section 11.9 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall be ineffective to the
extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof in that jurisdiction or affecting the validity or
enforceability of such provision in any other jurisdiction.

     Section 11.10 Interest.

     (a) In no event shall the amount of interest due or payable hereunder or
under the Notes exceed the maximum rate of interest allowed by Applicable Law,
and in the event any such payment is inadvertently made by the Borrower or
inadvertently received by any Lender, then such excess sum shall be credited as
a payment of principal, unless the Borrower shall notify the Administrative
Agent or such Lender in writing that it elects to have such excess returned
forthwith. It is the express intent hereof that the Borrower not pay and the
Lenders not receive, directly or indirectly in any manner whatsoever, interest
in excess of that which may legally be paid by the Borrower under Applicable
Law.

     (b) Notwithstanding the use by the Lenders of the Base Rate, the Federal
Funds Rate, and the Eurodollar Rate as reference rates for the determination of
interest on the Loans, the Lenders shall be under no obligation to obtain funds
from any particular source in order to charge interest to the Borrower at
interest rates related to such reference rates.

     Section 11.13 Entire Agreement. Except as otherwise expressly provided
herein, this Agreement and the other documents described or contemplated herein
embody the entire agreement and understanding among the parties hereto and
thereto and supersede all prior agreements and understandings relating to the
subject matter hereof and thereof.

     Section 11.14 Other Relationships. No relationship created hereunder or
under any other Loan Document shall in any way affect the ability of the

termination of this Agreement and the payment and performance of all other
Obligations.

     Section 11.17 Senior Debt. The Indebtedness of the Borrower evidenced by
the Notes is secured by the Security Documents and is intended by the parties
hereto to be in parity with the Interest Hedge Agreements in effect from time to
time between the Borrower and any Lender and senior in right of payment to all
other Indebtedness for Money Borrowed of the Borrower.

     Section 11.18 Obligations Several. The obligations of the Administrative
Agent and each of the Lenders hereunder are several, not joint.

     Section 11.19 Confidentiality. The Lenders shall hold all non-public,
proprietary or confidential information (which has been identified as such by
the Borrower) obtained pursuant to the requirements of this Agreement in
accordance with their customary procedures for handling confidential information
of this nature and in accordance with safe and sound banking and investment
practices; however, the Lenders may make disclosure of any such information to
their examiners, Affiliates, internal and outside auditors, counsel,

of any Note or participation therein or as required or requested by any
governmental authority or representative thereof or in connection with the
enforcement hereof or of any Loan Document or related document or pursuant to
legal process or with respect to any litigation between or among the Borrower
and any of the Lenders. In no event shall any Lender be obligated or required to
return any materials furnished to it by the Borrower. In addition, the Lenders
may make disclosure of such information to any direct or indirect contractual
counterparty in swap agreements or such contractual counterparty's professional
advisors (so long as such contractual counterparty or professional advisors to

                                   ARTICLE 5.

                    REPRESENTATIONS AND WARRANTIES OF SELLER

        Seller hereby makes the following representations and warranties to
Purchaser:

        5.1. Organization and Standing. Seller is a corporation duly organized,
validly existing and in good standing under the laws of the state of its
incorporation, and has full corporate power and authority to enter into and
perform this Agreement.

        5.2. Authorization and Binding Obligations. The execution, delivery and
performance of this Agreement by Seller have been duly and validly authorized by
all necessary corporate action, including approval of the entire transaction by
the requisite vote of the board of directors of Seller. This Agreement has been
duly executed and delivered by Seller and constitutes a valid and binding
agreement of Seller enforceable against it in accordance with its terms, except
as its enforceability may be limited by bankruptcy, insolvency, moratorium or
other laws relating to or affecting creditors' rights generally and the exercise
of judicial discretion in accordance with general equitable principles.

        5.3. No Contravention. Except as otherwise contemplated hereunder, the
execution, delivery and performance of this Agreement, the consummation of the
transactions contemplated hereby and the compliance with the provisions hereof
by Seller 



                                      -6-
<PAGE>   7

will not (a) violate any provisions of the corporate charter or bylaws of
Seller, (b) result in the breach of, or constitute a default under, or result in
the creation of any lien, charge or encumbrance upon the Authorization under the
provisions of any agreement or other instrument to which Seller is a party or by
which the property of Seller is bound or affected or (c) violate any laws,
regulations, orders or judgments applicable to Seller.

        5.4. Authorization. The Authorization is not, or will not be on the
Closing Date, subject to any agreements or restrictions that would inhibit or
prevent Seller from assigning the same to Purchaser free and clear of any and
all liens and encumbrances. Furthermore, there are no, and there will not be on
the Closing Date, any agreements that may effect the validity of the
Authorization or Purchaser's right to own or hold the same now or in the future,
nor are there any agreements that may affect Seller's right to own, hold or
assign the Authorization to Purchaser as contemplated by this Agreement. The
Authorization is validly issued in the name of Seller and is in full force and
effect. The Authorization is unimpaired by any acts or omissions of Seller (or
any of its Representatives) and the Authorization is free and clear of any
restrictions which might limit the full operation of a system constructed to
provide cellular telephone services under the authority of the Authorization.

        The Authorization is not and will not be materially and adversely
affected by any of the rights or obligations created under Article VI of the
CTSI Loan Agreement (hereinafter collectively referred to as the "Article VI
Rights") or by the transfer of any of the Article VI Rights to Purchaser, and
the existence of the Article VI Rights does not constitute, and will not cause,
a violation of FCC rules, regulations or orders, or the rules or regulations of
any other governmental authority having jurisdiction over the Authorization. The
creation of the Article VI Rights did not grant an interest in the FCC
application for the Authorization that was or is in violation of the rules,
regulations or orders of the FCC, and does not grant an interest in the
Authorization that was or is in violation of the rules, regulations or orders of
the FCC. The existence of the Article VI Rights did not have to be reported to
the FCC while the FCC application for the Authorization was pending and does not
have to be reported to the FCC in connection with the assignment of the
Authorization to Purchaser under the rules, regulations and orders of the FCC.

        5.5. Litigation. There is no action, order, writ, injunction, judgment
or decree outstanding or claim, suit, litigation, proceeding, or labor dispute
("Action"), other than rule-making proceedings affecting the cellular telephone
industry generally, pending or, to the knowledge of Seller, threatened or
anticipated against, relating to or affecting (a) Seller, (b) the Authorization,
or (c) the transactions contemplated by this Agreement. Seller is not in default
with respect to any judgment, order, writ, injunction or decree of any court or
governmental agency, and there are no unsatisfied judgments against Seller or
the Authorization. There is not a reasonable likelihood of an adverse
determination of any pending Action which would, individually or in the
aggregate, have a material adverse effect on the Seller or the Authorization.



                                      -7-
<PAGE>   8

        5.6. Complaints. There is not any Commission investigation, notice of
apparent liability or order of forfeiture pending or outstanding against Seller
respecting any violation, or allegation thereof, of any Commission rule,
regulation or policy, or, to the best of Seller's knowledge, any complaint
before the Commission as a result of which an investigation, notice of apparent
liability or order of forfeiture may issue from the Commission relating to the
System, nor is there any basis for any such claim.

        5.7. Reports. All returns, reports and statements currently required to
be filed by Seller with the Commission or with any other governmental agency
with respect to the Authorization have been filed and substantially complied
with and shall continue to be filed and be in substantial compliance on a
current basis until the Closing Date. All such reports, returns and statements
are (or will be, in the case of future reports) substantially complete and
correct as filed.

        5.8. Taxes. Seller has filed, or caused to be filed, with the
appropriate federal, state and local governmental agencies all required tax and
information returns, and Seller has paid, caused to be paid or accrued all
taxes, excise taxes, assessments, charges, penalties and interest shown to be
due and payable or claimed to be due and payable thereon.

        5.9. No Brokers. Neither Seller nor any of its Affiliates have entered
into or will enter into any contract, agreement, arrangement or understanding
with any person or firm which will result in the obligation of Purchaser to pay
any finder's fee, brokerage commission or similar payment in connection with the
transactions contemplated hereby.

        5.10. Miscellaneous. No representation or warranty made by Seller in
this Agreement, and no statement made in any schedule, exhibit, certificate or
other document furnished pursuant to this Agreement, contains or will contain
any untrue statement of a material fact or knowingly omits or fails to state, or
will omit or fail to state, any material fact or information necessary to make
such representation or warranty or any such statement not materially misleading.


                                   ARTICLE 6.

                   REPRESENTATIONS AND WARRANTIES OF PURCHASER

        6.2. Authorization and Binding Obligations. The execution, delivery and
performance by Purchaser of this Agreement has been duly and validly authorized
by all necessary corporate action, including any necessary approval of the
entire transaction by the board of directors of Purchaser. This Agreement has
been duly executed and delivered by Purchaser and constitutes a valid and
binding agreement of Purchaser, enforceable against Purchaser in accordance with
its terms except as its enforceability may be limited by bankruptcy, insolvency,
moratorium or other laws relating to or affecting creditors' rights generally
and the exercise of judicial discretion in accordance with general equitable
principles.

        6.3. No Contravention. Except as otherwise contemplated hereunder, the
execution, delivery and performance of this Agreement, the consummation of the
transactions contemplated hereby and the compliance with the provisions hereof
by Purchaser will not (a) violate any provisions of the corporate charter or
by-laws of Purchaser, or (b) violate any laws, regulations, orders or judgments
applicable to Purchaser.

        6.4. Litigation. There is no Action, other than rule-making proceedings
affecting the cellular telephone industry generally, pending or, to the
knowledge of Purchaser, threatened or anticipated against, relating to or
affecting Purchaser that would have a material adverse effect Purchaser's
ability to consummate the transactions contemplated by this Agreement. There is
not a reasonable likelihood of an adverse determination of any pending Action
which would, individually or in the aggregate, have a material adverse effect on
Purchaser's ability to consummate the transactions contemplated by this
Agreement.

        6.5. Qualification of Purchaser. Purchaser is familiar with the
Communications Act of 1934, as amended, and the existing rules, regulations,
policies and orders of the FCC. There is no fact known to Purchaser that would
under the Act and existing rules, regulations, policies and orders of the FCC
disqualify Purchaser from acquiring the Authorization from Seller.

        6.6. No Brokers. Neither Purchaser nor any of its Affiliates have
entered into or will enter into any contract, agreement, arrangement or
understanding with any person or firm which will result in the obligation of
Seller to pay any finder's fee, brokerage commission or similar payment in
connection with the transactions contemplated hereby.

        6.7. Miscellaneous. No representation or warranty made by Purchaser in
this Agreement, and no statement made in any schedule, exhibit, certificate or
other document furnished pursuant to this Agreement, contains or will contain
any untrue statement of a material fact or knowingly omits or fails to state, or
will omit or fail to state, any material fact or information necessary to make
such representation or warranty or any such statement not materially misleading.

                                 INDEMNIFICATION

        10.1. Survival. The several representations, warranties, covenants, and
agreements of the Parties contained in this Agreement (or in any document
delivered in connection herewith) shall be deemed to have been made on the date
of this Agreement and on the Closing Date, shall be deemed to be material and to
have been relied upon by the Parties notwithstanding any investigation made by
the Parties, shall survive the Closing Date, and shall remain operative and in
full force and effect for a period of three (3) years following the Closing
Date; provided, however, that the representations, warranties and agreements of
Seller contained in Section 5.4 (Authorization) shall continue for the duration
of any applicable statute of limitations. The period during which the several
representations, warranties, covenants and agreements shall survive and continue
is referred to herein as the "indemnification period."

        10.2.  Seller's Indemnity.

               10.2.1. During the indemnification period (or thereafter solely
with respect to any claim for which indemnification has been made prior to the
expiration of the indemnification period), Seller shall indemnify and hold
harmless Purchaser and its Affiliates from and against any and all demands,
claims, losses, liabilities, actions or causes of action, assessments, actual
damages (but excluding consequential damages), fines, taxes (including, without
limitation, excise and penalty taxes), penalties, reasonable costs and expenses
(including, without limitation, interest, reasonable expenses of investigation,
reasonable fees and disbursements of counsel, accountants and other experts
(whether such reasonable fees and disbursements of counsel, accountants and
other experts relate to claims, actions or causes of action asserted by
Purchaser against Seller or asserted by third parties)) (collectively "Losses")
incurred or suffered by Purchaser, its Affiliates, and their



                                      -12-
<PAGE>   13

respective officers, directors, employees, agents and representatives, arising
out of, resulting from, or relating to:

                      (a) Any breach of any of the representations or warranties
made by Seller in this Agreement or in any agreement, certificate, exhibit or
other instrument delivered by the Seller pursuant to this Agreement; and

                      (b) Any failure by Seller to perform any of its covenants
or agreements contained in this Agreement or in any agreement, certificate or
other instrument delivered by the Seller pursuant to this Agreement.

        10.3.  Purchaser's Indemnity.

               10.3.1. During the indemnification period (or thereafter solely
with respect to any claim for which indemnification has been made prior to
expiration of the indemnification period), in addition to any other
indemnification provided for under this Agreement, Purchaser shall indemnify and
hold harmless Seller and its Affiliates from and against any and all Losses
incurred or suffered by Seller, its Affiliates, and their respective officers,
directors, employees, agents and representatives, arising out of, resulting
from, or relating to:

                      (a) Any breach of any of the representations or warranties
made by Purchaser in this Agreement or in any agreement, certificate or other
instrument delivered by Purchaser pursuant to this Agreement; or

                      (b) Any failure by Purchaser to perform any of its
covenants or agreements contained in this Agreement or in any agreement,
certificate or other instrument delivered by Purchaser pursuant to this
Agreement.

        10.4. Procedure. In the event that any party hereto shall sustain or
incur any Losses in respect of which indemnification may be sought by such party
pursuant to this Article, the party seeking such indemnification (the
"Indemnitee") shall assert a claim for indemnification by giving prompt written
notice thereof (the "Notice") which shall describe in reasonable detail the
facts and circumstances upon which the asserted claim for indemnification is
based along with a copy of the claim or complaint, to the party providing
indemnification (the "Indemnitor") and shall thereafter keep the Indemnitor
reasonably informed with respect thereto; provided that failure of the
Indemnitee to give the Indemnitor prompt notice as provided herein shall not
relieve the Indemnitor of any of its obligations hereunder, except to the extent
that the Indemnitor is materially prejudiced by such failure. For purposes of
this paragraph, any notice which is sent within 15 days of the date upon which
the Indemnitee learned of such Loss shall be deemed to have been a "prompt
notice."



                                      -13-
<PAGE>   14

               10.4.1. If the Indemnitor wishes to defend any claim for any
Losses for which such Indemnitor is or may be liable, and such Indemnitor first
establishes (to the reasonable satisfaction of the Indemnitee) the Indemnitor's
financial ability to pay for any such Losses, then such Indemnitor may, at its
own expense, defend such claim; provided that the Indemnitee may retain counsel
(at the Indemnitee's expense) to monitor the defense of such claim, and may take
over such defense if, during the course thereof, it reasonably appears that the
Indemnitor has lost its ability to pay for any Losses threatened by such claim.
If an Indemnitor assumes the defense of such an action, no compromise or
settlement thereof may be effected by the Indemnitor without the Indemnitee's
consent, which consent shall not be unreasonably withheld. If an Indemnitor
fails, within thirty (30) days after the date of the Notice, to give notice to
the Indemnitee of said Indemnitor's election to assume the defense thereof, said
Indemnitor shall be bound by any determination made in such action or any
compromise or settlement thereof effected by the Indemnitee.

               10.4.2. Amounts payable by the Indemnitor to the Indemnitee in
respect of any Losses for which any party is entitled to indemnification
hereunder shall be payable by the Indemnitor as incurred by the Indemnitee.

        10.5.  Indemnification Payments in Cash.  All payments in respect to any
indemnification obligation shall be made in cash.

        10.6. Investigations: Waivers. The survival periods and rights to
indemnification provided for in this Article shall remain in effect
notwithstanding any investigation at any time by or on behalf of any party
hereto or any waiver by any party hereto of any condition to such party's
obligations to consummate the transactions contemplated hereby.

                                   ARTICLE 11.

                                   TERMINATION

        Absence of Commission Consent. This Agreement may be terminated at the
option of Seller or Purchaser upon written notice to the other if the Assignment
Application has not been granted by Final Order within twelve (12) months after
the date of this Agreement. Neither party may terminate this Agreement pursuant
to this Section if such party is in material default hereunder, or if a delay in
any decision or determination by the Commission respecting the Assignment
Application has been caused or materially contributed to by such party's action
or inaction with respect to such Assignment Application.

                                   ARTICLE 12.

                              INTERIM CONSTRUCTION

        Nothing in this Agreement shall be construed as restricting Seller's
right to undertake any construction activity that Seller may deem necessary or
appropriate in order to comply with FCC construction obligations. It is
acknowledged that such activity may include the participation or assistance of
GCSI, and may involve the utilization of an SCS 800 switch; the co-licensing of
existing facilities in the RSA; or by entering into a lease arrangement and
operating agreement with Purchaser as the current provider of services in the
RSA. No such construction or activity shall affect any of the terms and
conditions of this Agreement.


                                   ARTICLE 13.

                                  MISCELLANEOUS

        13.1. Assignment. Except as provided below, neither this Agreement nor

        13.3. Specific Performance. The obligations of Seller and Purchaser

either party may sue in equity for specific performance, and the parties
expressly waive the defense that a remedy in damages will be adequate.

        13.4. Choice of Law. This Agreement shall be construed, interpreted and
the rights of the Parties determined in accordance with the laws of the State of
Delaware, except with respect to matters of law concerning the internal
corporate affairs of any corporate entity which is a party to or the subject of

the respective entity derives its powers shall govern.

        13.5. Entire Agreement; Amendments and Waivers. This Agreement, together
with all exhibits and schedules hereto, constitutes the entire agreement among
the parties pertaining to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the parties. No supplement, modification or waiver of this Agreement
shall be binding unless executed in writing by the party to be bound thereby. No
waiver of any of the provisions of this Agreement shall be deemed or shall
constitute a waiver of any other provision hereof (whether or not similar), nor
shall such waiver constitute a continuing waiver unless otherwise expressly
provided.

        13.6. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which

contained in this Agreement or in any other instrument referred to herein,
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall not affect any
other provision of this Agreement or any other such instrument. If the
invalidity, illegality or unenforceability of any provision causes or is likely
to have a material adverse affect on the benefits of the bargain for either of
the parties then the parties agree to negotiate in good faith to re-establish
the relative benefits of the bargain, and if they are not able to do so within a
period of sixty (60) days after such provision is declared or found to be
invalid, illegal or unenforceable, then this Agreement shall become of no
further force or effect.

        13.8. Headings. The headings of the Articles and Sections herein are
inserted for convenience of reference only and are not intended to be a part of
or to affect the meaning or interpretation of this Agreement.

Purchaser elects to exclude the Leadville Site from the Assets to be acquired by
it, it shall so notify Seller in writing of that decision within fifteen (15)
days of Purchaser's receipt of a completed phase II environmental study of the
Leadville Site, but in no event less than thirty (30) days prior to the Closing
Date. The exclusion of the Leadville Site from the Assets shall not exclude any
other Assets located on or at the Leadville Site, and shall not result in any
adjustment of the Purchase Price. Any expenses associated with the deactivation,
removal, storage or transport of the Leadville Assets as a result of Purchaser's
exercise of its right under this Section 2.1.1 shall be the responsibility of
Purchaser.

        2.2. Purchase Price. The purchase price for the Assets shall be eighteen

($1,000,000) of such Purchase Price shall be delivered to an escrow agent
jointly selected by Purchaser and Seller that is located the in Southern
California, which amount shall be held by the escrow agent in escrow for a
period of one (1) year following the Closing Date pursuant to the terms of an
escrow agreement the terms of which shall be substantially similar to those
contained in the agreement attached hereto as Schedule 2.2. Such escrow shall
secure the obligations of Seller pursuant to the indemnification provisions
contained in Article 11 hereof; and (ii) the balance of such Purchase Price
shall be paid to Seller by certified or official bank check or by bank wire
transfer of immediately available funds, at the option of Seller.

        2.3.   Adjustments and Prorations.

               2.3.1. Pursuant to the procedures prescribed in Sections 2.3.3
and 2.3.4, as the case may be, the Purchase Price shall be adjusted in
accordance with the following:

                      2.3.1.1. The Purchase Price shall be increased by the
current assets of Seller as of the Closing Date, which shall be the sum of (i)
Adjusted Accounts Receivable as of the Closing Date, (ii) Inventory, and (iii)
prepaid expenses (including rent, deposits and taxes) assigned to Purchaser. For
purposes of this Section 2.3, "Adjusted Accounts Receivable" shall equal the sum
of the following:

                      100% of the amount of all accounts receivable outstanding
                      from the date of billing ("Outstanding") for less than 31
                      days; plus

                      90% of the amount of all accounts receivable that are more
                      than 30 days Outstanding, but less than 61 days
                      Outstanding; plus

                      75% of the amount of all accounts receivable that are more
                      than 60 days Outstanding, but less than 91 days
                      Outstanding.



                                                                               7

<PAGE>   8

                      There shall be no adjustment (i.e. 0%) for any accounts 
                      receivable that are more than 90 days Outstanding.

                      2.3.1.2. The Purchase Price shall be decreased by the
current liabilities of the Seller as of the Closing Date, which shall be the sum
of (i) all Liabilities that relate to Seller's operation of the System, the
Business and the Assets on or prior to Closing (including, without limitation,
accounts payable, the current portion of any long-term Liabilities and accrued
and payable taxes), (ii) subscriber deposits, and (iii) Deferred Access Revenue
assumed by Purchaser; provided, however, it shall not include lease or contract
liabilities being assumed by Purchaser pursuant to Section 3.1.2 of this
Agreement.

               2.3.2. In addition, all revenues and all expenses arising from
operation of the System before and after the Closing Date, including resale
charges and other expenses payable in respect to cellular telephone services,
utility charges, real and personal property taxes and assessments levied against
the Assets, property and equipment rentals, sales and service charges, taxes
(except for taxes arising from the transfer and assignment of the Assets
hereunder), and similar prepaid and deferred items, shall be prorated between
Seller and Purchaser in accordance with the principle that Seller shall receive
the benefit of all revenues, and be responsible for all expenses, costs,
obligations and liabilities associated with ownership and operation of the
System for the period on or prior to the Closing Date, and Purchaser shall
receive the benefit of all revenues, and be responsible for all expenses, costs,
obligations and liabilities associated with the ownership and operation of the
System after the Closing Date.

               2.3.3. A final settlement of all adjustments or prorations made
under this Section, with payment being made by the appropriate Party in cash,
shall occur no later than sixty (60) days after the Closing Date. Within such
sixty (60) day period Purchaser shall provide Seller with a written statement,
together with reasonable supporting documentation, of any final adjustments or
prorations required by this Section 2.3.

               2.3.4. In the event that the Parties cannot agree on the amount
of the final adjustments or prorations, the determination shall be made by the
Denver, Colorado office of one of the "Big 6" national accounting firms selected
by Seller that has not, during the prior three (3) years, been employed by
either of the Parties ("Auditor"). The Auditor shall make the determination
based on the express provisions of this Agreement; provided, however, that if
the Auditor finds the express terms of this Agreement are not sufficient to
resolve any issue or issues, the Auditor shall rely upon generally accepted
accounting principles then in effect. Either Party may invoke the use of the
Auditor by notifying the other Party in writing, provided that neither Party may
invoke the use of the Auditor to determine the final adjustments or prorations
earlier than forty (40) days after the Closing Date. The Auditor shall be
required to render a decision within twenty-one (21) days after the Auditor is
requested to render a determination under this Section. The decision of the
Auditor shall be binding on the Parties and not subject to any judicial
challenge by either



                                                                               8

<PAGE>   9

Party. Within five (5) business days after the Auditor provides the
determination to the Parties, the final payment shall be made in accordance with
that determination. The expenses of the Auditor shall be paid by Seller and
Purchaser in reciprocal proportion to the allocation to Seller and Purchaser of
the amount in disagreement, as the case may be. For example, if the amount in
disagreement is One Hundred Thousand Dollars ($100,000) and the Auditor
determines that the Seller should receive Seventy Thousand Dollars ($70,000) and
the Purchaser should receive Thirty Thousand Dollars ($30,000), then Seller
shall pay thirty percent (30%) of the Auditor's expenses, and Purchaser shall
pay seventy percent (70%).

        2.4. Allocation of Purchase Price. The Purchase Price, as adjusted
pursuant to Section 2.3, shall be allocated in accordance with Schedule 2.4, to
be prepared on or before the Closing and Purchaser and Seller agree to cooperate
reasonably in the preparation of such Schedule. Each of the Parties agrees that
(i) such allocation represents the fair market value of the Assets and shall be
binding upon it; (ii) no filings made by it with any taxing or other authority
shall reflect an allocation other than in the manner agreed upon; and (iii) it
shall timely make all filings required by any taxing authority, including the
filing of Internal Revenue Service Form 8594. A preliminary allocation is
attached as Schedule 2.4. The final allocation shall be generally consistent
with Schedule 2.4.

whatsoever or any debts, liabilities (contingent or otherwise) or obligations
relating to the System.

               3.1.2. Purchaser shall assume and timely pay or perform all of
Seller's liabilities and obligations (i) for which there has been an adjustment

Service, in form satisfactory to Purchaser, that ensures that the SPUs will be
issued in a timely manner after the Closing.

                                   ARTICLE 5.

        5.7. Contracts. Schedule 5.7 is a list of all Contracts other than
Customer Agreements. Each Contract is in full force and effect, paid currently,
and has not been materially impaired by any acts or omissions of Seller or any
of its Representatives. Except as set forth on Schedule 5.7, no Contract
requires the consent of any other contracting party to the transactions
contemplated by this Agreement. Seller is not (and, to its best knowledge, no
other party is) in material breach or violation of, or default under any of the
Contracts. Seller is not aware of any intent by any party to any Contract to
terminate or amend the terms thereof or to refuse to renew any Contract upon the
expiration of its term. Seller has delivered to Purchaser true and correct
copies of all the Contracts (or in the case of oral contracts, true and correct
descriptions thereof). Purchaser is under no obligation to assume the
obligations under those Contracts which Purchaser notifies Seller that Purchaser
chooses not to assume not later than fourteen (14) days after the Parties'
execution of this Agreement.

        5.8. Intellectual Property. Schedule 5.8 is a list of all Intellectual
Property. No person has a right to receive a royalty or similar payment in
respect of any Intellectual Property other than as indicated on Schedule 5.8
Seller has no licenses granted by or to it, or any other agreements to which it
is a party, relating in whole or in part to any of the Intellectual Property
other than as indicated on Schedule 5.8 To Seller's best knowledge, Seller's use
of the Intellectual Property is not infringing upon or otherwise violating the
rights of any third party, and no proceedings have been instituted against or
notices received by Seller alleging that such use of the Intellectual Property
infringes upon or otherwise violates any rights of a third party.

        5.9. Employees; Employment Obligations. Seller and/or the System
currently employs those persons in those positions and at those salaries
(including benefits) as are listed on Schedule 5.9. Except as otherwise set
forth on such Schedule 5.9, Seller and the System are not bound, and at no time
have been bound, by any oral or written collective bargaining agreement,
severance, pension, retirement, profit-sharing, 401(k), "employee benefit plan"
(within the meaning of Section 3(3) of the Employee Retirement Income Security
Act of 1974, as amended), or other employment agreement (other than any
agreements terminable on thirty (30) days' or less notice without penalty or
severance obligation) with any officer, employee or consultant, nor does Seller
or the System have any liability under any such agreement which was terminated
previously. Seller has complied in all material respects with all applicable
laws, rules and regulations which relate to prices, wages, hours, discrimination
in employment and collective bargaining and to the operation of the System and
is not liable for any arrears of wages or any taxes or penalties for failure to
comply with any of the foregoing. With respect to each "employee benefit plan,"
if any, within the meaning of Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), which is now, or ever has been,
maintained, contributed to, or required to be contributed to by Seller, such
employee benefit plan has been established and maintained in all material
respects in accordance with its terms and in compliance with all applicable
laws, statutes, orders, rules and regulations, including but not limited to
ERISA. Seller is not a party to, and is not affected by or, to the best of



                                                                              16

Seller's knowledge, threatened with, any dispute or controversy with a union or
with respect to unionization or collective bargaining involving the employees of
Seller or the System.

        5.10. Financial Statements. Attached hereto as Schedule 5.10 is a list
of unaudited financial reports relating to the System ("Financial Statements").
Schedule 5.10 also lists documents which set forth the available historical data
on System subscribers and their local and roaming minutes of use of Services
("Operating Data Statements"). On a monthly basis Seller will provide to
Purchaser updated, unaudited Financial Statements and Operating Data Statements
covering periods between execution hereof and the Closing Date. All Financial
Statements are (or shall be) true and correct in all material respects, have
been (or shall have been) prepared from the books and records of Seller and
fairly present (or shall fairly present) the financial position of Seller in a
manner consistent with prior periods as of the dates of such statements and the
results of the Business operations and statements of cash flow for the year or
interim period then ended, in each case in conformity with generally accepted
accounting principles then in effect. Seller has not incurred nor is it subject
to any liabilities or obligations, whether accrued, absolute or contingent,
which are not required to be disclosed in the Financial Statements and are not
so disclosed. All Operating Data Statements are (or shall be) accurate in all
material respects.

the knowledge of Seller, threatened or anticipated against, relating to or
involving (a) Seller, (b) the Assets, (c) the Business, or (d) the transactions
contemplated by this Agreement. Seller is not in material default with respect
to any material judgment, order, writ, injunction or decree of any court or
governmental agency relating to or involving (i) Seller, (ii) the Assets, (iii)
the Business, or (iv) the System, and there are no unsatisfied judgments against
Seller or the Assets. There is not a reasonable likelihood of an adverse
determination of any pending Action which would, individually or in the
aggregate, have a material adverse effect on the Assets or the Business or the
financial condition of Seller.

        5.12. Complaints. There is not, to the best of Seller's knowledge, any
Commission investigation, notice of apparent liability or order of forfeiture
pending or outstanding against Seller or the System respecting any violation, or
allegation thereof, of any Commission rule, regulation or policy, or, to the
best of Seller's knowledge, any complaint before the Commission as a result of
which an investigation, notice of apparent liability or order of forfeiture may
issue from the Commission relating to the System.

        5.13. Reports. Except as set forth in Schedule 5.13 hereto, Seller has
filed and complied with all returns, reports and statements currently required
to be filed by Seller with the Commission or with any other governmental agency
with respect to the System.



                                                                              17

Seller shall continue to make and comply with such filings until the Closing
Date. All such reports, returns and statements are (or will be, in the case of
future reports) substantially complete and correct as filed.

caused to be filed, with the appropriate federal, state and local governmental
agencies all required tax and information returns and reports which are due or
required to be filed at the date hereof, and Seller has paid, caused to be paid
or accrued all Taxes shown to be due and payable or claimed to be due and
payable thereon to the date hereof. Except as disclosed on Schedule 5.14, Seller
has no liability material in amount, contingent or otherwise, for any Taxes.
Except as disclosed on Schedule 5.14 hereto, Seller has received neither notice
of nor is otherwise aware of any audit or examination relating to its Taxes; nor
is Seller a party to any action or proceeding by any governmental authority for
assessment or collection of Taxes; nor has any claim for assessment and
collection been asserted against Seller, nor has Seller executed a waiver of any
statute of limitations with respect thereto. Seller has not received any notices
and is not otherwise aware of any deficiencies, adjustments or changes in
assessments with respect to any Taxes other than as set forth on Schedule 5.14
hereto. No extensions of time are in effect for the assessment of deficiencies
for Taxes in respect of any fiscal period.

        5.15. No Other Agreements to Sell the System or the Assets. Seller has
no legal obligation, absolute or contingent, to any other person or firm to sell
the Assets or to sell any capital stock of Seller or to effect any merger,
consolidation or other reorganization of Seller or to enter into any agreement
with respect thereto.

        5.16. Resale and Roaming Agreements. Schedule 5.16 contains a list of
all resale agreements to which Seller is a party, both as reseller and as a
provider of resale services to others. Schedule 5.16 also contains a list of all
roaming agreements to which Seller is a party. All such resale and roaming
agreements are in full force and effect and reflect terms reasonable and
customary in the cellular telephone industry as of the time they were entered
into.

Person acting on behalf of Seller has released any other Person from any claims

of Substances at any Operating Site; (d) no Liens have been, or are, imposed on
any of the Assets under any Environmental Laws; and (e) Seller has obtained all
permits, licenses, registrations, and other approvals and has made all reports
and notifications required under any Environmental Laws in connection with the
Assets, and is in compliance in all material respects with all applicable
Environmental Laws; provided, however, that the



                                                                              18

<PAGE>   19

representations and warranties in this Section regarding acts or omissions by
parties other than Seller are made to the best knowledge of Seller. Schedule
5.17 hereto also contains a list and brief description of all filings by Seller
with, notices to Seller from, and related reports to all governmental

the date hereof, including without limitation, filings made, corrective action
taken, or citations received by Seller.

Associates, Inc. to assist it with this transaction. Seller shall be solely
responsible for all fees and costs payable to, or as a result of using, such

               5.20.1. any issuance, assumption or guarantee by Seller of

organized, validly existing and in good standing under the laws of the state of

and operate the System and Assets and to carry on the Business associated with
the Assets as now being conducted, and (c) is duly qualified to do business and
is in good standing as a foreign corporation in every jurisdiction in which the
nature of the business conducted by it requires such qualification, except where
the failure to so qualify would not materially adversely affect Purchaser.

        6.1. Authorization and Binding Obligations. The execution, delivery and
performance by Purchaser of this Agreement has been duly and validly authorized
by all necessary corporate action, including any necessary approval of the

binding agreement of Purchaser, enforceable against Purchaser in accordance with
its terms except as its enforceability may be limited by bankruptcy, insolvency,
moratorium or other laws relating to or affecting creditors' rights generally
and the exercise of judicial discretion in accordance with general equitable
principles.

        6.2. No Contravention. Except as otherwise contemplated hereunder, the
execution, delivery and performance of this Agreement, the consummation of the
transactions contemplated hereby and the compliance with the provisions hereof
by Purchaser will not (a) violate any provisions of the corporate charter or

the provisions of any agreement or other instrument to which Purchaser is a
party or by which the property of Purchaser is bound or affected or (c) violate

contemplated by this Agreement. Purchaser is not in material default with
respect to any material judgment, order, writ, injunction or decree of any court
or governmental agency, and there are no unsatisfied judgments against
Purchaser.

effect on Purchaser's ability to consummate the transactions contemplated by
this Agreement.

financially and otherwise qualified under the Communications Act of 1934, as
amended, to hold the FCC Authorizations and to consummate the transactions

asserted by Purchaser against Seller or asserted by third parties))
(collectively "Losses") incurred or suffered by Purchaser, its Representatives
or its assigns arising out of, resulting from, or relating to:

                      11.2.1.1. Any breach of any of the representations
warranties, covenants, agreements or other commitments made by Seller in this
Agreement or in any agreement, certificate, exhibit or other instrument
delivered by the Seller pursuant to this Agreement; and

                      11.2.1.2. Any failure by Seller to perform any of its
covenants or agreements contained in this Agreement or in any agreement,
certificate or other instrument delivered by the Seller pursuant to this
Agreement.

        11.3.         Purchaser's Indemnity.



                                                                              25
<PAGE>   26

               11.3.1. During the indemnification period (or thereafter solely
with respect to any claim for which indemnification has been made prior to
expiration of the indemnification period), in addition to any other
indemnification provided for under this Agreement, from and after the Closing
Date, Purchaser shall indemnify and hold harmless Seller and its Representatives
and its assigns from and against any and all Losses incurred or suffered by
Seller, its Representatives or its assigns arising out of, resulting from, or
relating to:

                      11.3.1.1. Any breach of any of the representations or
warranties made by Purchaser in this Agreement or in any agreement, certificate
or other instrument delivered by Purchaser pursuant to this Agreement; or

                      11.3.1.2. Any failure by Purchaser to perform any of its
covenants or agreements contained in this Agreement or in any agreement,
certificate or other instrument delivered by Purchaser pursuant to this
Agreement.

        11.4. Procedure. In the event that any Party hereto shall sustain or
incur any Losses in respect of which indemnification may be sought by such Party
pursuant to this Article 11, the Party seeking such indemnification (the
"Indemnitee") shall assert a claim for indemnification by giving prompt written
notice thereof (the "Notice") which shall describe in reasonable detail the
facts and circumstances upon which the asserted claim for indemnification is
based along with a copy of the claim or complaint, to the Party providing
indemnification (the "Indemnitor") and shall thereafter keep the Indemnitor
reasonably informed with respect thereto; provided that failure of the
Indemnitee to give the Indemnitor prompt notice as provided herein shall not
relieve the Indemnitor of any of its obligations hereunder, except to the extent
that the Indemnitor is materially prejudiced by such failure. For purposes of
this Section, any notice which is sent within fifteen (15) days of the date upon
which the Indemnitee learned of such Loss shall be deemed to have been a  prompt
notice.

               11.4.1. If the Indemnitor wishes to defend any claim for any
Losses for which such Indemnitor is or may be liable, and such Indemnitor first
establishes (to the reasonable satisfaction of the Indemnitee) the Indemnitor's
financial ability to pay for any such Losses, then such Indemnitor may, at its
own expense, defend such claim; provided that the Indemnitee may retain counsel
(at the Indemnitee's expense) to monitor the defense of such claim, and may take
over such defense if, during the course thereof, it reasonably appears that the
Indemnitor has lost its ability to pay for any Losses threatened by such claim.
If an Indemnitor assumes the defense of such an action, no compromise or
settlement thereof may be effected by the Indemnitor without the Indemnitee's
consent, which consent shall not be unreasonably withheld. If an Indemnitor
fails, within thirty (30) days after the date of the Notice, to give notice to
the Indemnitee of said Indemnitor's election to assume the defense thereof, said
Indemnitor shall be bound by any determination made in such action or any
compromise or settlement thereof effected by the Indemnitee.

               11.4.2. Amounts payable by the Indemnitor to the Indemnitee in
respect of any Losses for which any Party is entitled to indemnification
hereunder shall be payable by the Indemnitor as incurred by the Indemnitee.



                                                                              26
<PAGE>   27

        11.5. Limitation on Indemnification. No Party shall be entitled to
indemnification in accordance with the provisions of this Article until such
time as the value of the aggregate loss or liability for which indemnification
is sought exceeds the sum of Fifty Thousand Dollars ($50,000). At such time as
the aggregate loss or liability for which indemnification may be sought exceeds
Fifty Thousand Dollars ($50,000), the Party to be indemnified may seek
indemnification for all such losses or liabilities, including the first Fifty
Thousand Dollars ($50,000), provided further that in no event shall the
aggregate liability of either Party for all such claims exceed Five Million
Dollars ($5,000,000).

        11.6. Indemnification Payments in Cash. All payments in respect to any
indemnification obligation shall be made by wire transfer of immediately
available funds.

        11.7. Investigations: Waivers. The survival periods and rights to
indemnification provided for in this Article 11 shall remain in effect
notwithstanding any investigation at any time by or on behalf of any Party
hereto or any waiver by any Party hereto of any condition to such Party's
obligations to consummate the transactions contemplated hereby.

        11.8. Claims Outside the Indemnification Period. Any claim made outside
the Indemnification Period shall be barred.


                                   ARTICLE 12.

                              DEFAULT AND REMEDIES

        12.1. Opportunity to Cure. If any Party believes another to be in
default hereunder for breach of representations and warranties or any other
reason, such Party shall provide the other with written notice specifying in
reasonable detail the nature of such default. If the default has not been cured
by the earlier of: (a) the Closing Date, or (b) within thirty (30) days after
delivery of that notice, then the Party giving such notice may terminate this
Agreement by notifying the defaulting Party and/or exercise the remedies
available to such Party pursuant to this Article 12, subject to the right of the
other Party to contest either such action through appropriate proceedings;
provided, however, that if such breach is not capable of being cured within such
period and if the breaching Party shall have commenced action to cure such
breach within such period and is diligently attempting to cure such breach and
such breach can reasonably be expected to be cured during the additional time
period, the breaching Party shall be afforded an additional reasonable amount of
time to cure such breach but not to exceed an additional sixty (60) days;
provided, further, however, that Purchaser shall have no opportunity to cure the
breach of its obligation to deliver any required portion of the Purchase Price
to be delivered to Seller at Closing.

        12.2. Remedies. Except as otherwise provided in this Agreement, the
Parties hereto shall have the right to pursue any remedy that each may have at
law or in equity. Without limiting the foregoing, the Parties agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the Parties shall be entitled
to an injunction or injunctions to prevent breaches of this Agreement and to
enforce specifically the terms and provisions hereof in any court of the



                                                                              27
<PAGE>   28

United States or any state having jurisdiction, this being in addition to any
other remedy to which they are entitled at law or in equity. Each Party agrees
that it will not assert, as a defense against a claim for specific performance,
that the Party seeking specific performance has an adequate remedy at law.


                                   ARTICLE 13.

                                   TERMINATION

        Absence of Commission Consent. This Agreement may be terminated at the
option of Seller or Purchaser upon written notice to the other if the Assignment
Application has not been granted by Final Order within twelve (12) months after
the date of this Agreement. Neither Party may terminate this Agreement pursuant
to this Section if such Party is in material default hereunder, or if a delay in
any decision or determination by the Commission respecting the Assignment
Application has been caused or materially contributed to by such Party's action
or inaction with respect to such Assignment Application.


                                   ARTICLE 14.

                              DAMAGE; RISK OF LOSS

        14.1. Risk of Loss. The risk of loss or damage to the Assets shall be
upon Seller at all times prior to the Closing Date. In the event of material
loss or damage to the Assets prior to the Closing Date, Seller shall promptly
notify Purchaser thereof and use its best efforts to repair, replace or restore
the lost or damaged Assets to their former condition as soon as possible. If
such repair, replacement, or restoration has not been completed prior to the
Closing Date, Purchaser may, at its option:

               14.1.1. elect to consummate the Closing and make such
arrangements as the Parties may reasonably agree upon to remedy such loss or
damage; or

               14.1.2. elect to postpone the Closing Date, with prior consent of
the Commission if necessary, for such reasonable period of time (not to exceed
ninety (90) days) as is necessary for Seller to repair, replace, or restore (or
to cause to be repaired, replaced or restored) the lost or damaged Assets to
their former condition. If, after the expiration of that extension period, the
lost or damaged Assets have not been adequately repaired, replaced or restored,
Purchaser may terminate this Agreement by notifying Seller or elect to
consummate the Closing as provided in Section 14.1.1.

        For purposes of this Section, loss or damage shall be deemed "material"
if the reasonable cost to repair, replace, or restore the lost or damaged
property exceeds $250,000.00.

        14.2. Resolution of Disagreements. If the Parties are unable to agree
upon the extent of any loss or damage, the cost to repair, replace or restore
any lost or damaged Assets, the adequacy of any repair, replacement, or
restoration of any lost or damaged Assets, or any other matter arising under
this Section, the Parties shall jointly refer the 



                                                                              28
<PAGE>   29
disagreement to a qualified consulting communications engineer mutually
acceptable to Seller and Purchaser who is a member of the Association of Federal
Communications Consulting Engineers (the  Engineer ), whose decision shall be
final, and whose fees and expenses shall be paid one-half by Seller and one-half
by Purchaser. The Engineer shall render his decision not later than thirty (30)
days after the date on which the disagreement is jointly referred.

                                   ARTICLE 15.

                                  MISCELLANEOUS

        15.1. Assignment. Neither this Agreement nor any of the rights or
obligations hereunder may be assigned by Seller or Purchaser without the prior
written consent of the others, except that Purchaser, upon ten (10) days notice
to Seller, may assign its right, title and interest in, to and under this
Agreement to an Affiliate, provided, however that Western Wireless Corporation
shall continue to guaranty performance of the assignee s obligations under this
