                                   (UNAUDITED)

1.      Certain information and footnote disclosures normally included in
        financial statements prepared in accordance with generally accepted
        accounting principles have been condensed or omitted pursuant to Article
        10 of Regulation S-X of the Securities and Exchange Commission. The
        accompanying unaudited condensed consolidated financial statements
        reflect, in the opinion of management, all adjustments necessary to
        achieve a fair statement of financial position and results for the
        interim periods presented. All such adjustments are of a normal
        recurring nature. It is suggested that these condensed consolidated
        financial statements be read in conjunction with the financial
        statements and notes thereto included in the Annual Report of Powertel,
        Inc. ("Powertel" or the "Company") on Form 10-K for the year ended
        December 31, 1997.

2.      Certain prior year amounts have been reclassified to conform to the
        current period presentation.

3.      Effective with the three months ended December 31, 1997, the Company
        adopted Statement of Financial Accounting Standards No. 128, "Earnings
        Per Share" ("SFAS 128"), which requires the restatement of all prior
        period earnings per common share ("EPS") amounts. The components of EPS
        and their derivation as required under SFAS 128 are as follows:

           Average common shares outstanding                              26,965            26,812
           Diluted earnings per share                                $     (2.14)       $    (1.10)
</TABLE>


        Basic EPS was computed by dividing net loss by the weighted average
        number of shares of Common Stock outstanding during the quarter. Diluted
        EPS is the same as basic EPS because all Common Stock equivalents would
        have an antidilutive effect.

         Powertel's PCS licenses encompass a territory of approximately 246,000
contiguous square miles with a population of approximately 24.3 million people
in the Major Trading Areas ("MTAs") of Atlanta, Georgia; Jacksonville, Florida;
Memphis, Tennessee/Jackson, Mississippi; and Birmingham, Alabama (the "Current
PCS Markets") and in 13 Basic Trading Areas ("BTAs") in Kentucky and Tennessee
(the "Kentucky/Tennessee BTAs"). The Company first introduced its PCS services
in October 1996 in Jacksonville, Florida and Montgomery, Alabama and, to date,
has launched its PCS services in a total of 25 markets in the Southeast. In all
of these markets, except Atlanta, Georgia, where the Company acquired its
licenses from GTE Mobilnet Incorporated in 1996, the Company was the first to
offer PCS services commercially. Powertel intends to continue to rapidly build
out its PCS network and to launch its PCS services. As of March 31, 1998, the
Company had approximately 157,000 PCS subscribers.

         Average revenues per subscriber in the wireless industry have declined
during recent quarters and are expected to continue to gradually decline in the
future. The Company believes this downward trend is the result of the addition
of lower usage customers who utilize wireless service for personal convenience,
security or as backup for their traditional landline telephones. In addition,
the Company expects that revenue per minute will continue to decline as
competition within the wireless industry intensifies. The Company believes the
effect of this trend on the Company's earnings will be mitigated by
corresponding increases in the number of wireless subscribers and the use of
enhanced services that will be offered to PCS subscribers.

         As a result of: (i) the significant costs required to build out and
maintain the PCS system, hire and manage the required personnel to operate the
PCS business and market its services; (ii) the subsidization of PCS handsets to
customers; and (iii) the depreciation of PCS equipment and amortization of the
PCS licenses, the Company incurred a net loss of $57.7 million for the three
months ended March 31, 1998. The Company expects to continue incurring
significant operating losses during 1998 and thereafter as it continues to build
out its PCS system, develop its PCS customer base and subsidize the cost of PCS
handsets to its customers.

         Minimizing customer attrition, or "churn," becomes a greater challenge
as the subscriber base grows and the wireless marketplace becomes more
competitive. The Company achieved an average monthly churn rate of 1.6% and 3.5%
for its cellular and PCS businesses, respectively, for the three months ended
March 31, 1998. The Company remains focused on improving its PCS churn rate in
the near future through more focused collections efforts, stricter credit
evaluation policies and a proactive customer retention program. However, the
Company expects that ongoing PCS churn rates could be higher than comparable
churn rates for cellular carriers due to the fact that the Company does not
require long-term service contracts. Additionally, the ability of PCS
subscribers to activate service via the phone ("over the air activation")
without any face-to-face contact with Company representatives increases the
Company's susceptibility to subscription fraud, which ultimately results in
churn.

         The Company is a member of the North American GSM Alliance (the
"Alliance"), a consortium of eight PCS carriers which offer PCS service using
the Global System for Mobile Communication ("GSM") throughout North America. All
members of the Alliance have executed roaming agreements with each other,
thereby allowing GSM customers to roam throughout many major metropolitan areas
in the United States and Canada. Additionally, the Company has signed several
roaming agreements and expects to sign numerous others with international GSM
carriers to facilitate international roaming.

         In late 1998 the Company plans to launch a dual-mode (GSM and analog
cellular) product offering and new, network-based pre-pay plans. The Company is
currently negotiating both in-region and out-of-



                                       7

region roaming agreements with cellular carriers to allow the Company's PCS
customers to roam on cellular systems in those areas where a GSM network is not
available. The Company must upgrade its billing system to allow the Company to
bill for dual-mode services and network-based pre-pay plans. Failure by the
Company to successfully launch these new services in a timely manner, to
accurately bill for these services or to enter into dual-mode roaming agreements
with carriers covering a substantial portion of North America where GSM networks
are not available could negatively impact the Company's ability to attract and
retain customers requiring such services.

RESULTS OF OPERATIONS

         The following table reflects the composition of the Company's cellular
and PCS service revenue and equipment sales, and related gross margins, as well
as overall operating and other costs and margins. The Company's historical
results of operations, particularly in view of the Maine Disposition and the
start-up costs associated with the Company's PCS business, will not be
comparable with future periods.

THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31, 1997

         The following discussion reflects the Company's results of operations
for its PCS and cellular lines of business. All general corporate costs have
been allocated to the PCS line of business.

         Service revenue from local customers increased $15.0 million, or 133%,
for 1998, as compared to 1997. PCS service revenue from local customers
increased $17.9 million, or 326%, over the first quarter of 1997 as a result of
the continued rapid increase in subscribers (to approximately 157,000 at March
31, 1998, from approximately 35,000 at March 31, 1997), which is due in part to
the launch of several new markets during 1997. Cellular service revenue from
local customers decreased $2.9 million, or 51%, primarily as a result of the
Maine Disposition, which occurred during the second quarter of 1997 and the
corresponding reduction in customers (to approximately 27,000 at March 31, 1998,
from approximately 50,000 at March 31, 1997).

          The average monthly service revenue per local PCS subscriber was
$57.23 versus $63.52 a year ago. This decrease is primarily attributable to
changes in the Company's rate plan offerings from 1997 to 1998. At March 31,
1997, the majority of the Company's PCS subscribers were participants in a
promotional plan under which they received unlimited monthly airtime for local
calling for a fixed monthly fee of $50 (the "Prestige Partners"). In 1998, the
Company's subscriber base has a choice of multiple rate plan offerings with
fixed monthly access charges ranging from $10 to $90 and monthly unlimited toll
packages from $5 to $15.

          During the first quarter of 1998, the Prestige Partners were
transitioned from unlimited, flat rate local service to measured service rate
plans. The Company's average revenue per PCS subscriber increased for the first
quarter of 1998 as compared to the fourth quarter of 1997 primarily due to the
transition of the Prestige Partners. The Company anticipates marginal declines
in future periods primarily due to lower minute usage by new wireless
subscribers and increased price competition among competing wireless carriers.
The Company believes that this is consistent with a general trend in the
wireless industry of declining average monthly revenue per subscriber.

          The average monthly service revenue per local cellular subscriber
(excluding roaming revenue and equipment sales) decreased to $37.92 for the
first quarter of 1998, as compared to $39.40 for the same period a year ago. The
Company believes that this decrease is consistent with industry trends over
recent years of declining average monthly revenue per cellular subscriber. The
Company believes that this decline reflects the continuing industry-wide growth
of more convenience-oriented, lower-use subscribers as well as pricing pressures
related to increased competition.

          The Company generated $.8 million in PCS roaming revenue during the
first quarter of 1998 as compared to none a year ago. This increase reflects the
success of the previously mentioned roaming agreements with Alliance partners
that became effective during the last five months of 1997. Cellular roaming
revenue decreased $.3 million, or 18%, for the first quarter of 1998, as
compared to the same period in 1997. This decrease is attributable to the Maine
Disposition.

         Other service revenue, which includes activation and installation fees,
fees from vertical services and interconnection fees billed to local exchange
carriers ("LECs") for connections to the Company's PCS network, increased $.5
million, or 41%, for the first quarter of 1998, as compared to the same period
in 1997. This increase is due primarily to the activation fees associated with
the addition of new PCS subscribers and the increase in interconnection fees as
a result of increased traffic on the Company's PCS network.

         Cost of services includes the cost of: (i) interconnection with LEC
facilities; (ii) direct cell site costs (e.g., property taxes and insurance,
site lease costs and electric utilities); (iii) PCS and cellular roaming
validation (provided by third-party clearinghouses); (iv) long distance toll
costs; (v) cellular cloning and fraud; and (vi) supplementary services (such as
voice mail). PCS cost of services increased $4.7 million or 109% for the first
quarter of 1998, as compared to the same period in 1997. This increase primarily
reflects the interconnection and tower lease costs associated with the
approximately 500 cell sites that have been placed in service since March 31,
1997 in the Company's expanding PCS network. Cellular cost of services decreased
$.6 million, or 58%, in 1998 as compared to 1997 primarily as a result of the
Maine Disposition and a significant decrease in costs associated with cloning
and subscription fraud in the InterCel division during 1998.

         The Company generated a negative PCS equipment margin of 163% on $6.4
million of sales during the first quarter of 1998, as compared to a negative
margin of 133% on $4.8 million of sales for the same period in 1997. The
increase in negative PCS equipment margins during the first quarter of 1998
reflects an increase in the percent of handset sales to the Company's agents and
mass merchants where the equipment subsidy is higher. The Company generated a
negative cellular equipment margin of 136% on $.2 million of sales during the
first quarter of 1998, as compared to a negative margin of 250% on $.2 million
of sales for the same period in 1997. This change is primarily attributable to
the Maine Disposition. The Company expects to continue subsidizing the cost of
PCS and cellular handsets to consumers for the foreseeable future.



                                       10

         Operations costs, which include the costs of maintaining the cellular
and PCS systems, customer service, credit and collections and inventory
management totaled $10.4 million for first quarter of 1998 while PCS operations
costs totaled $9.9 million, a 255% increase over the same period a year ago,
primarily as a result of the costs associated with the Company's significantly
expanded network and a significant increase in the bad debt provision resulting
from the disconnection of non-paying customers. Cellular operations costs
totaled $.5 million for the quarter, a 54% decrease from 1997, which is
attributable primarily to the Maine Disposition.

         Selling and marketing costs totaled $11.9 million for the first quarter
of 1998, an increase of $6.7 million, or 128%, from the same period of 1997.
Substantially all of this increase is attributable to ongoing PCS advertising
costs, as well as the costs of all direct and indirect sales channels, including
commissions incurred as a result of the continued rapid growth in the number of
PCS subscribers.

         General and administrative costs ("G&A") were $8.1 million for the
first quarter of 1998, an increase of only $.5 million from the same period of
1997. PCS G&A costs, which totaled $7.7 million for the quarter, increased 14%
from the same period of 1997 primarily as a result of an increase in the number
of employees and the related increase in facilities costs at the Company's
corporate and regional administrative offices and information technology center.
The increase in PCS G&A was partially offset by a $.5 million decrease in
cellular G&A resulting from the Maine Disposition.

         Depreciation and amortization for the first quarter of 1998 totaled
$15.3 million, a 61% increase over the same period in 1997, and consisted
principally of the depreciation of the cellular and PCS network and the
amortization of PCS licenses. Substantially all of this increase is attributable
to the depreciation associated with the approximately 500 PCS cell sites that
have been placed in service since March 31, 1997 and the amortization costs
associated with the Atlanta MTA license which was placed into service during
July 1997.

         Net consolidated interest expense totaled $21.8 for the first quarter
of 1998 as compared to $4.5 million for the same period in 1997. This increase
reflects: (i) the additional interest costs associated with the $300 million
11.125% Senior Notes due June 2007 (the "1997 Notes"); (ii) the lower
availability of funds for investment due to the buildout of the PCS network; and
(iii) a reduction in capitalized interest ($.7 million in 1998 as compared to
$6.7 million in 1997), which is attributable to the completion and placing in
service of substantial portions of the PCS system.

          The effective income tax rate for the first quarters of both 1998 and
1997 was 0%. The Company generated a $57.7 million net loss during the first
quarter of 1998 and expects to continue to incur significant operating losses
throughout the remainder of 1998 and beyond. The tax benefit of these operating
losses will not be recognized until management determines that it is more likely
than not that such benefit is realizable.

LIQUIDITY AND CAPITAL RESOURCES

         The Company requires significant amounts of capital for funding the
operations and expansion of its PCS business. Total capital expenditures,
including capital expenditures for information technology and the support of the
PCS business, totaled approximately $35 million for the first quarter of 1998.
Costs associated with the PCS system buildout include tower sites, leasehold
improvements, base station and switch equipment and labor expenses related to
construction of sites. The Company currently estimates that capital expenditures
will total approximately $195 million for the remainder of 1998 relating to the
initial buildout of the PCS systems in the Kentucky/Tennessee BTAs and the
continued expansion of its Current PCS Markets and its cellular system. By the
end of 1998, the Company expects to be able to offer PCS services in markets
containing approximately 60% of the population within its PCS markets. Wireless
coverage is expected to extend across most metropolitan areas, certain secondary
cities and major connecting highway corridors within the PCS markets.
Thereafter, based on customer demand and competitive factors, the Company
intends to continue to build out its PCS system to enhance and expand its
coverage. The Company anticipates that it will need to raise additional
financing in the event it decides to make acquisitions of additional licenses or
businesses or expand and enhance the existing PCS coverage in existing PCS
markets.

         In May 1997, the Company sold its cellular operations in the State of
Maine to Rural Cellular Corporation ("Rural Cellular"). On the closing date,
Rural Cellular paid the Company $71.8 million in cash and paid $5.4 million into
escrow. On November 3, 1997, the $5.4 million was released from escrow to the


                                       11
<PAGE>   12

Company. In addition, Rural Cellular reimbursed the Company approximately
$250,000 for capital expenditures made on its behalf prior to the closing of the
transaction.

         On June 10, 1997, the Company issued $300 million principal amount of
the 1997 Notes (together with the previously issued Senior Discount Notes due
February 2006 and the Senior Discount Notes due May 2006, the "Notes") in a
private offering. In September 1997, the Company exchanged substantially all of
the private 1997 Notes for substantially identical notes that were registered
under the Securities Act of 1933, as amended (the "Securities Act"). The Company
used $89.6 million of the proceeds from the 1997 Notes to purchase and pledge,
for the benefit of the holders of the 1997 Notes, certain U.S. government
securities to provide for the payment of the first six scheduled interest
payments on the 1997 Notes.

         On June 5, 1997, pursuant to a Stock Purchase Agreement, dated as of
May 23, 1997, between the Company and The Huff Alternative Income Fund, L.P.
("Huff"), the Company issued to Huff 50,000 shares of nonvoting Series C
Convertible Preferred Stock for an aggregate purchase price of $22.5 million.
Also, on June 5, 1997, pursuant to a Stock Purchase Agreement, dated as of May
23, 1997, between the Company and SCANA Communications, Inc. ("SCANA"), the
Company issued to SCANA 50,000 shares of nonvoting Series D Convertible
Preferred Stock (together with the Series C Convertible Preferred Stock, the
"Preferred Stock"), for an aggregate purchase price of $22.5 million. The Series
C Convertible Preferred Stock and Series D Convertible Preferred Stock become
convertible on December 5, 1998 and March 14, 2002, respectively, at the option
of the holder, into Common Stock at a conversion price of $12.75, subject to
adjustment. Both series of Preferred Stock are redeemable at the option of the
Company, in whole or in part, on a pro rata basis, at a redemption price of $450
per share plus declared and unpaid dividends, anytime subsequent to June 5,
2002. Both series of Preferred Stock have a liquidation preference over the
Common Stock of $450 per share plus declared and unpaid dividends in the event
of a liquidation, dissolution or winding up of the Company. Both series of
Preferred Stock rank, as to dividends, on parity with the Common Stock.

        On March 4, 1996, Powertel PCS, Inc., a wholly owned subsidiary of the
Company ("Powertel PCS"), entered into a $125 million credit agreement (the
"Credit Agreement") with Ericsson Inc. ("Ericsson") regarding the purchase of
and vendor financing for PCS equipment and services. On October 31, 1996, March
31, 1997, June 26, 1997 and November 18, 1997, Powertel PCS and Ericsson entered
into amendments to the Credit Agreement, which increased the equipment financing
commitment to $165 million and amended certain other provisions of the Credit
Agreement. During the fourth quarter of 1997, the $165 million commitment under
the Credit Agreement was syndicated to a group of lenders. On December 23, 1997,
the Credit Agreement was amended to increase the financing commitment to $265
million. On February 6, 1998, Powertel PCS and the lenders entered into an
amended and restated Credit Agreement to incorporate the terms and conditions of
the original agreement and the subsequent amendments.

         Although the Company is currently unable to predict with certainty the
amount of expenditures that may be made beyond 1998, the Company expects that it
will require additional capital. Sources of additional capital may include
vendor financing, cash flow from operations, public and private equity and debt
financing and asset dispositions by the Company. The Company may also require
additional financing in the event it decides to make acquisitions of additional
licenses or businesses. The extent of additional financing required will
partially depend on the success of the Company's businesses. The Company
currently has no other sources of income or cash flows other than its cellular
and PCS operations and the interest income earned from investing its cash and
the proceeds of the public and private debt and equity offerings which were
completed during 1997 and 1996. There can be no assurance that additional
financing will be available to the Company or, if available, that it can be
obtained on terms acceptable to the Company and within the limitations contained
in the indentures to the Notes, the Credit Agreement or any future financing
arrangements. The restrictions on additional indebtedness under the indentures
to the Notes require the Company to satisfy specified leverage ratios in order
to incur indebtedness; however, they permit the Company and its subsidiaries to
incur an unlimited amount of additional indebtedness to finance the acquisition
of inventory or equipment.

         The Company expects to incur significant operating losses and to
generate significant negative cash flow from operating activities in the future,
while it develops and constructs its PCS system and builds a PCS customer base.
Cash interest will not be payable on the 12% Senior Discount Notes due February
2006 and the 12% Senior Discount Notes due May 2006 (collectively, the "Senior
Discount Notes") prior to 2001. Management believes that cash flow from
operations may be insufficient to repay the Notes or any additional financing
that the Company may obtain in full at maturity and that they may need to be
refinanced. There can be no assurance that any such refinancing could be
effected successfully or on terms acceptable to the Company.


                                       12
<PAGE>   13

         During the first quarter of 1998, the Company used net cash of $59.0
million for operating activities, as compared to $35.7 million for the same
period in 1997. Operating activities for 1998 included $57.7 million of net
loss, $15.3 million of depreciation and amortization, $14.3 million of bond
accretion on the Senior Discount Notes and $31.7 million related to changes in
assets and liabilities.

         Cash used in investing activities was $41.5 million for the first
quarter of 1998, as compared to $23.2 million provided from investing activities
for the same period in 1997. Investing activities for 1998 consisted primarily
of capital expenditures totaling $34.7 million and a decrease in accrued
construction costs of $5.2 million (both primarily related to the buildout of
the PCS system and support systems).

        Cash provided from financing activities was $15.0 million for the first
quarter of 1998, as compared to $34.5 million for the same period in 1997.
Financing activities for 1998 consisted primarily of borrowings of $14.7 million
under the Credit Agreement.

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1997, the FASB issued Statement of Financial Accounting
Standards No. 130 ("FAS 130"), "Reporting Comprehensive Income," and Statement
of Financial Accounting Standards No. 131 ("FAS 131"), "Disclosures About
Segments of an Enterprise and Related Information." Both statements are
effective for fiscal years beginning after December 15, 1997. FAS 130 did not
have an impact on the Company, and FAS 131 is not anticipated to have a material
impact on the Company's financial statements.

         In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5 ("SOP 98-5"), "Reporting on the Costs of
Start-Up Activities," which is effective for fiscal years beginning after
December 15, 1998. SOP 98-5 requires entities to expense certain start-up costs
and organization costs as they are incurred. The Company does not anticipate
that this statement will have an impact on its financial statements.

OTHER

         The Year 2000 issue is the result of potential problems with computer
systems or any equipment with computer chips that use dates where the date has
been stored as just two digits (e.g., "97" for 1997). On January 1, 2000, any
clock or date recording mechanism including date sensitive software which uses
only two digits to represent the year 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 disruption of operations, including among other things,
a temporary inability to process transactions, send invoices or engage in
similar activities.

         The Company is currently working to address and resolve this issue with
respect to its computerized information systems. The Company is also discussing
the Year 2000 issue with its significant suppliers to determine the extent to
which the Company is vulnerable to those third parties' failure to remediate
their own Year 2000 issues. The Company presently believes that with conversions
to new systems and modifications to existing software the Year 2000 issue can be
mitigated. The Company is currently utilizing and will continue to utilize
internal and external resources to implement, reprogram or replace and test
software and related assets affected by the Year 2000 issue. The Company expects
to complete the majority of its efforts in this area by early 1999 leaving
adequate time to assess and correct any significant issues that may materialize.
However, if such modifications and conversions are not made, or are not timely,
or if systems from third parties on which the Company's systems rely will not be
converted on time or if such third parties fail to convert or if such
conversions are incompatible with the Company's systems, the Year 2000 issue
could have a material adverse impact on the Company's business, financial
condition and results of operations.

         Management does not believe that the costs to resolve its Year 2000
issues will be material to the Company. The costs of the project and the
timetable in which the Company plans to complete the Year 2000 compliance
requirements are based on management's best estimates, which were derived
utilizing numerous assumptions of future events including the continued
availability of certain resources, third party modification plans and other
factors. However, there can be no assurance that these estimates will be
achieved and actual



                                       13
<PAGE>   14

results could differ materially from these plans. Specific factors that might
cause such material differences include, but are not limited to, the
availability and cost of personnel trained in this area, the ability to locate
and correct all relevant computer codes and similar uncertainties.

ITEM 1.    LEGAL PROCEEDINGS

         Reference is made to the Company's Form 10-K for the year ended
December 31, 1997 (as filed with the Commission on March 24, 1998) for a
discussion of certain legal proceedings. In addition to the legal proceedings
discussed therein, the Company is subject from time to time to legal proceedings
that arise out of the Company's business operations, including in connection
with service, billing and collection matters. Although the actual damages sought
in such legal proceedings are generally small, certain of these legal
proceedings may seek punitive damages and/or attempt to be certified as class
actions. While the Company currently does not expect such legal proceedings to
have a material adverse effect on the Company, no assurance can be given that
the resolution of any or all of such legal proceedings will not have a material
adverse effect on the Company's business, financial condition or results of
operations.

                                   ARTICLE II

                        AMOUNTS AND TERMS OF THE ADVANCES

                  SECTION 2.01. Advances. Subject to the terms and conditions of
this Agreement and in reliance upon the representations and warranties of the
Borrower herein set forth, each Lender hereby severally agrees to make the
Advances described in subsections 2.01(a) and 2.01(b):

                  (a) Series A Advances. Each Lender having a Series A
         Commitment severally agrees, subject to the terms and conditions
         hereinafter set forth, to make Series A Advances to the Borrower from
         time to time on any Business Day during the period from the date hereof
         until the Termination Date in an aggregate amount not to exceed such
         Lender's Series A Commitment at such time. The original amount of each
         Lender's Series A Commitment is set forth opposite its name on Schedule
         2.01(a) annexed hereto and the aggregate original amount of the Series
         A Commitments is $165,000,000; provided that the Series A Commitment of
         each Lender shall be adjusted to give effect to any assignments of the
         Series A Commitments pursuant to Section 8.07 hereof; and provided
         further that the amount of each Lender's Series A Commitment shall be
         reduced by the amount of each Series A Advance made by such Lender.
         Each Borrowing made under this Section 2.01(a) shall consist of Series
         A Advances made simultaneously by the Lenders having Series A
         Commitments ratably according to their Series A Commitments. Amounts
         borrowed under this Section 2.01(a) and repaid or prepaid may not be
         reborrowed.

                  (b) Series B Advances. Each Lender having a Series B
         Commitment severally agrees, subject to the terms and conditions
         hereinafter set forth, to make Series B Advances to the Borrower from
         time to time on any Business Day during the period from the date hereof
         until the Termination Date in an aggregate amount not to exceed such
         Lender's Series B Commitment at such time. The original amount of each
         Lender's Series B Commitment is set forth opposite its name on Schedule
         2.01(b) annexed hereto and the aggregate original amount of the Series
         B Commitment is $100,000,000; provided that the Series B Commitment of
         each Lender shall be adjusted to give effect to any assignments of the
         Series B Commitments pursuant to Section 8.07 hereof; and provided
         further that the amount of each Lender's Series B Commitment shall be
         reduced by the amount of each Series B Advance made by such Lender.
         Each Borrowing under this Section 2.01(b) shall consist of Series B
         Advances made simultaneously by the Lenders having Series B Commitments
         ratably according to their Series B Commitments. Amounts borrowed under
         this Section 2.01(b) and repaid or prepaid may not be reborrowed.
         Notwithstanding anything herein to the contrary, no Series B Advances
         shall be made hereunder until the full amount of all Advances available
         under the Series A Commitments have been drawn. The Series B
         Commitments and the Series B Advances thereunder shall be pari passu
         with the Series A Commitments and the Series A Advances, respectively,
         and all Commitments and Advances shall be subject to and made in
         accordance with the terms of this Agreement.

                  SECTION 2.02. Making the Advances. (a) Each Borrowing shall be
in a minimum amount of $5,000,000 and shall be made on notice, given not later
than 11:00 A.M.


<PAGE>   19

(New York City time) on the third Business Day prior to the date of the proposed
Borrowing to the Administrative Agent, which shall give to each Lender prompt
notice thereof by telex or telecopier. Each such notice of a Borrowing (a
"Notice of Borrowing") shall be deemed a request by the Borrower to finance the
payment of an invoice or invoices delivered by Ericsson pursuant to the
Equipment Purchase Agreement. Each Notice of Borrowing shall be by telephone,
confirmed immediately in writing, or telex or telecopier, in substantially the
form of Exhibit B hereto, specifying therein the requested (i) date of such
Borrowing, (ii) aggregate amount of such Borrowing, and (iii) identifying the
invoices to be financed with the proceeds of such Borrowing; provided that if
the Borrower elects to pay an invoice and subsequently finance such invoice with
a Borrowing, such Borrowing must occur within ninety days of the date of the
invoice being financed. Each Lender shall, before 11:00 A.M. (New York City
time) on the date of such Borrowing, make available for the account of its
Applicable Lending Office to the Administrative Agent at the Administrative
Agent's Account, in same day funds, such Lender's ratable portion of such
Borrowing in accordance with the respective Commitments of such Lender and the
other Lenders. After the Administrative Agent's receipt of such funds and upon
fulfillment of the applicable conditions set forth in Article III, the
Administrative Agent will make such funds available to the Borrower as directed
in the Notice of Borrowing. The Borrower hereby expressly agrees that the
obligation of the Borrower to make any payments under this Agreement shall be
unconditional and absolute irrespective of any claim, set-off, defense or other
right that the Borrower may have at any time under the Equipment Purchase
Agreement and the rights and obligations of the Borrower thereunder are separate
and independent from this Agreement.

                  (b) Each Notice of Borrowing shall be irrevocable and binding
on the Borrower. The Borrower shall indemnify each Lender against any loss, cost
or expense incurred by such Lender as a result of any failure to fulfill on or
before the date specified in such Notice of Borrowing for such Borrowing the
applicable conditions set forth in Article III, including, without limitation,
any loss (including loss of anticipated profits), cost or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired by
such Lender to fund the Advance to be made by such Lender as part of such
Borrowing when such Advance, as a result of such failure, is not made on such
date.

                  (c) Unless the Administrative Agent shall have received notice
from a Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's ratable portion of such
Borrowing, the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the date of such Borrowing in
accordance with subsection (a) of this Section 2.02 and the Administrative Agent
may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If and to the extent that such Lender shall not
have so made such ratable portion available to the Administrative Agent, such
Lender and the Borrower severally agree to repay or pay to the Administrative
Agent forthwith on demand such corresponding amount and to pay interest thereon,
for each day from the date such amount is made available to the Borrower until
the date such amount is repaid or paid to the Administrative Agent, at the
interest rate applicable at such time under Section 2.05 to Advances comprising
such Borrowing. If such Lender shall pay to the Administrative Agent such
corresponding amount, such amount so paid shall constitute such Lender's Advance
as part of such Borrowing for all purposes.


<PAGE>   20


                  (d) The failure of any Lender to make the Advance to be made
by it as part of any Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its Advance on the date of such Borrowing,
but no Lender shall be responsible for the failure of any other Lender to make
the Advance to be made by such other Lender on the date of any Borrowing.

                  SECTION 2.03. Repayment of Advances. (a) The Borrower shall
repay to the Administrative Agent, for the ratable account of the Lenders, in
*** provided, however, that the last such installment shall be an amount
necessary to repay in full the unpaid principal amount of all Advances.

         (b)      The aggregate amount of the Advances made in each calendar 
year shall have the same amortization schedule, as contemplated in subsection
(a) above. If requested by any Lender from time to time, the Borrower agrees to
execute (i) a Note, in form and substance substantially the same as Exhibit A
hereto, in the aggregate amount of the Advances made in any calendar year and
reflecting the specific amortization schedule for such Advances and (ii) an
additional Note or Notes in the aggregate amount of any other Advances payable
to such Lenders and such Lender's unused Commitment. Upon the delivery of such
Notes, the Lender shall surrender to the Borrower the Note payable to such
Lender which had included the amount of the Advances made in such calendar year.

                  SECTION 2.04. Prepayments. (a) Optional. The Borrower may,
upon at least three Business Days' notice to the Administrative Agent stating
the proposed date and aggregate principal amount of the prepayment, and if such
notice is given the Borrower shall, prepay at the end of the calendar quarter
the outstanding aggregate principal amount of the Advances in whole or ratably
in part, together with accrued interest to the date of such prepayment on the
aggregate principal amount prepaid. Each such prepayment (i) shall be applied
pro rata between the outstanding Series A Advances and Series B Advances; and
(ii) shall be applied to reduce the scheduled principal installments of such
Advances due pursuant to Section 2.03 hereof (x) first in inverse order of
maturity to installments due after December 31, 2005 to the full extent thereof
and (y) second ratably to installments due on or before December 31, 2005.

                  (b) Mandatory. (i) No later than the first Business Day
following the date of receipt by the Borrower or any of its Subsidiaries of any
Net Cash Proceeds in excess of $5,000,000 in any 12 consecutive month period
("Excess Net Cash Proceeds"), the Borrower shall prepay the Advances in an
aggregate amount equal to such Excess Net Cash Proceeds. Notwithstanding the
foregoing, as long as no Default shall have occurred and be continuing, the
Borrower shall not be required to make any mandatory prepayment pursuant to this
Subsection 2.04(b)(i) to the extent the Excess Net Cash Proceeds are reinvested
in productive assets used by the Borrower and its Subsidiaries in the conduct of
its business within 180 days from the date of receipt thereof. If upon receipt
of any Excess Net Cash Proceeds, the Borrower elects to reinvest the Excess Net
Cash Proceeds as permitted under this Subsection 2.04(b)(i), (1) no later than
the first Business Day following receipt of such Excess Net Cash Proceeds, the
Borrower shall deliver an officers' certificate to the Administrative Agent
demonstrating the derivation of such Excess Net Cash Proceeds and certifying the
portion of such proceeds which the Borrower elects to reinvest in productive
assets and certifying that no Default shall have occurred and be continuing and
(2) upon the expiration of 180 days after the date of receipt of the Excess Net
Cash Proceeds certified as being scheduled for reinvestment, the Borrower shall
deliver to the Administrative Agent an officers' certificate indicating the
amount of Excess Net Cash Proceeds reinvested as of such date, the assets in
which such Excess Net Cash Proceeds have been reinvested, and the amount of any
remaining Excess Net Cash Proceeds which shall be applied to prepay the Advances
as set forth in this Subsection 2.04(b)(i).

                  (ii)  The Borrower shall prepay (A) all outstanding Advances,
upon the termination of the Equipment Purchase Agreement as a result of a
default thereunder by the Borrower and (B) all or a portion of the Advances
which corresponds to the amount of any refund required to be made by Ericsson in
accordance with the terms of the Equipment Purchase Agreement.

                  (iii) All prepayments under this Section 2.04(b) shall be made
together with accrued interest to the date of such prepayment on the aggregate
principal amount prepaid and shall be applied pro rata between the outstanding
Series A Advances and Series B Advances and shall be applied to reduce the
scheduled principal installments of such Advances due pursuant to Section 2.03
hereof in inverse order of maturity.

                  SECTION 2.05. Interest. (a) Scheduled Interest. (i) The
Borrower shall pay interest on the unpaid principal amount of each Advance owing
to each Lender from the date of such Advance until such principal amount shall
be paid in full, at a rate per annum equal at all times during each Interest
Period to the sum of (A) the then applicable Eurodollar Rate plus (B) the
Applicable Margin, payable in arrears on the last day of each Interest Period.

                  (ii) In the event that a Eurodollar Rate Advance is Converted
into a Base Rate Advance in accordance with Section 2.06(c) or (d) or any Base
Rate Advance is made, the Borrower shall pay interest on the unpaid principal
amount of such Base Rate Advance owing to each Lender from the date of such Base
Rate Advance until such principal amount shall be paid in full, at a rate per
annum equal at all times to the Base Rate in effect from time to time plus ***
payable in arrears on the last day of each calendar quarter.

<PAGE>   22


                  (b) Default Interest. Upon the occurrence and during the
continuance of a Default, the Borrower shall pay interest on (i) the unpaid
principal amount of each Advance owing to each Lender and (ii) to the fullest
extent permitted by law, the amount of any interest, fee or other amount payable
hereunder that is not paid when due, from the date such amount shall be due
until such amount shall be paid in full, payable in arrears on the date such
amount shall be paid in full and on demand, at a rate per annum equal at all
times to 2% per annum above the rate per annum then required to be paid on
Advances.

                  (c) Notice of Interest Rate. The Administrative Agent shall
determine the applicable Eurodollar Rate two Business Days before the first day
of each Interest Period after the date hereof and shall give the Borrower and
each Lender notice of the applicable interest rate determined by the
Administrative Agent for purposes of clause (a) as soon as possible after the
determination thereof.

                  (d) Compensation for Breakage or Noncommencement of Interest
Periods. The Borrower shall compensate each Lender, upon request of that Lender
(which request shall set forth the basis for requesting such amounts), for all
reasonable losses, expenses and liabilities (including any interest paid by that
Lender to lenders of funds borrowed by it to make or carry its Advances and any
loss, expense or liability sustained by that Lender in connection with the
liquidation or reemployment of such funds) which that Lender may sustain (i) if
for any reason (other than a default by that Lender) a borrowing of any Advances
bearing interest at the Eurodollar Rate does not occur on a date specified
therefor in a Notice of Borrowing or a telephonic request for borrowing, (ii) if
any prepayment (including prepayments pursuant to Section 2.04(b)) or other
principal payment of any Advance bearing interest at the Eurodollar Rate occurs
on a date prior to the last day of an Interest Period applicable to that
Advance, (iii) if any prepayment of an Advance bearing interest at the
Eurodollar Rate is not made on any date specified in a notice of prepayment
given by the Borrower, or (iv) as a consequence of any other default by the
Borrower in the repayment of any Advances bearing interest at the Eurodollar
Rate when required by the terms of this Agreement.

                  SECTION 2.06. Increased Costs, Etc. (a) If, due to either (i)
the introduction of or any change in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request from any central
bank or other governmental authority (whether or not having the force of law),
there shall be any increase in the cost to any Lender of agreeing to make or of
making, funding or maintaining Eurodollar Rate Advances and (ii) changes in the
basis of taxation of overall net income or overall gross income by the United
States or by the foreign jurisdiction or state under the laws of which such
Lender is organized or has its Applicable Lending Office or any political
subdivision thereof), then the Borrower shall from time to time, within 15 days
after demand by such Lender (with a copy of such demand to the Administrative
Agent), pay to the Administrative Agent for the account of such Lender
additional amounts sufficient to compensate such Lender for such increased cost;
provided, however, that a Lender claiming additional amounts under this Section
2.06(a) agrees to use reasonable efforts (consistent with its internal policy
and legal and regulatory restrictions) to designate a different Applicable
Lending Office if the making of such a designation would avoid the need for, or
reduce the amount of, such increased cost that may thereafter accrue and would
not, in the reasonable judgment of such Lender, be otherwise disadvantageous to
such Lender. Within 45 days after a Lender obtains knowledge of an increased
cost, such Lender shall notify the Borrower of the occurrence thereof and, as
soon as practicable thereafter, deliver to the


<PAGE>   23


Borrower a certificate setting out in reasonable detail the basis on which a
claim for increased cost is based, which certificate shall be conclusive and
binding for all purposes, absent manifest error.

                  (b) If any Lender reasonably determines that compliance with
any law or regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender and that the amount of such
capital is increased by or based upon the existence of such Lender's commitment
to lend and other commitments of such type, then, within 15 days after demand by
such Lender (with a copy of such demand to the Administrative Agent), the
Borrower shall pay to the Administrative Agent for the account of such Lender,
from time to time as specified by such Lender, additional amounts sufficient to
compensate such Lender in the light of such circumstances, to the extent that
such Lender reasonably determines such increase in capital to be allocable to
the existence of such Lender's commitment to lend hereunder. Within 45 days
after a Lender obtains knowledge of an increased cost, such Lender shall notify
the Borrower of the occurrence thereof and, as soon as practicable thereafter,
deliver to the Borrower a certificate setting out in reasonable detail the basis
on which such claim for increased cost is based, which certificate shall be
conclusive and binding for all purposes, absent manifest error.

                  (c) If the Required Lenders notify the Administrative Agent
that the Eurodollar Rate for such Advances will not adequately reflect the cost
to such Lenders of making, funding or maintaining their Eurodollar Rate
Advances, the Administrative Agent shall forthwith so notify the Borrower and
the Lenders in writing, whereupon (i) each such Eurodollar Rate Advance will
automatically Convert into a Base Rate Advance and (ii) the obligation of the
Lenders to make Eurodollar Rate Advances shall be suspended until the
Administrative Agent shall notify the Borrower that such Lenders have determined
that the circumstances causing such suspension no longer exist; provided,
however, the Lenders shall be obligated to make Base Rate Advances subject to
the terms and conditions hereof during the period that Eurodollar Rate Advances
shall be suspended.

                  (d) Notwithstanding any other provision of this Agreement, if
the introduction of or any change in or in the interpretation of any law or
regulation shall make it unlawful, or any central bank or other governmental
authority shall assert that it is unlawful, for any Lender or its Eurodollar
Lending Office to perform its obligations hereunder to make Eurodollar Rate
Advances or to continue to fund or maintain Eurodollar Rate Advances hereunder,
then, on notice thereof and demand therefor by such Lender to the Borrower
through the Administrative Agent, (i) each Eurodollar Rate Advance will
automatically, upon such demand, Convert into a Base Rate Advance and (ii) the
obligation of the Lenders to make Eurodollar Rate Advances shall be suspended
until the Administrative Agent shall notify the Borrower that such Lender has
determined that the circumstances causing such suspension no longer exist;
provided, however, that, before making any such demand, such Lender agrees to
use reasonable efforts (consistent with its internal policy and legal and
regulatory restrictions) to designate a different Eurodollar Lending Office if
the making of such a designation would allow such Lender or its Eurodollar
Lending Office to continue to perform its obligations to make Eurodollar Rate
Advances or to continue to fund or maintain Eurodollar Rate Advances and would
not, in the judgment of such Lender, be otherwise disadvantageous to such
Lender; provided further the Lenders shall be


<PAGE>   24

obligated to make Base Rate Advances subject to the terms and conditions hereof
during the period that Eurodollar Rate Advances shall be suspended.

                  SECTION 2.07. Payments and Computations. (a) The Borrower
shall make each payment hereunder and under the Notes, irrespective of any right
of counterclaim or set-off, not later than 11:00 A.M. (New York City time) on
the day when due in U.S. dollars to the Administrative Agent at the
Administrative Agent's Account in same day funds. The Administrative Agent will
promptly thereafter cause like funds to be distributed (i) if such payment by
the Borrower is in respect of principal, interest or any other Obligation then
payable hereunder and under the Notes to more than one Lender, to such Lenders
for the account of their respective Applicable Lending Offices ratably in
accordance with the amounts of such respective Obligations then payable to such
Lenders and (ii) if such payment by the Borrower is in respect of any Obligation
then payable hereunder to one Lender, to such Lender for the account of its
Applicable Lending Office, in each case to be applied in accordance with the
terms of this Agreement.

                  (b) The Borrower hereby authorizes each Lender, if and to the
extent payment owed to such Lender is not made when due hereunder or, in the
case of a Lender, under the Note held by such Lender, to charge from time to
time against any or all of the Borrower's accounts with such Lender any amount
so due.

                  (c) All computations of interest shall be made by the
Administrative Agent on the basis of a year of 360 days, in each case for the
actual number of days (including the first day but excluding the last day)
occurring in the period for which such interest is payable. Each determination
by the Administrative Agent of an interest rate hereunder shall be conclusive
and binding for all purposes, absent manifest error.

                  (d) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest; provided, however,
that, if such extension would cause payment of interest on or principal of
Eurodollar Rate Advances to be made in the next calendar month, such payment
shall be made on the next preceding Business Day.

                  (e) Unless the Administrative Agent shall have received notice
from the Borrower prior to the date on which any payment is due to any Lender
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each such Lender on
such due date an amount equal to the amount then due such Party. If and to the
extent the Borrower shall not have so made such payment in full to the
Administrative Agent, each such Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon, for each day from the date such amount is distributed to such
Lender until the date such Lender repays such amount to the Administrative
Agent, at the Federal Funds Rate.

                  SECTION 2.08. Tax Forms. Each Lender shall, on or prior to the
date of its execution and delivery of this Agreement in the case of each Initial
Lender and on the date of


<PAGE>   25


any assignment pursuant to Section 8.07, and from time to time thereafter as
requested in writing by the Administrative Agent (but only so long thereafter as
such Lender remains lawfully able to do so), provide the Administrative Agent
with two original Internal Revenue Service forms 1001 or 4224 or (in the case of
a Lender that has certified in writing to the Administrative Agent that it is
not a "bank" as defined in Section 881(c)(3)(A) of the Internal Revenue Code)
form W-8 (and, if such Lender delivers a form W-8, a certificate representing
that such Lender is not a "bank" for purposes of Section 881(c) of the Internal
Revenue Code, is not a 10-percent shareholder (within the meaning of Section
871(h)(3)(B) of the Internal Revenue Code) of the Borrower and is not a
controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Internal Revenue Code)) or form W-9, as appropriate, or
any successor or other form prescribed by the Internal Revenue Service,
certifying that such Lender is exempt from or entitled to a reduced rate of
United States withholding tax on payments pursuant to this Agreement or the
Notes or, in the case of a Lender providing a form W-8, certifying that such
Lender is a foreign corporation, partnership, estate or trust or in the case of
a Lender providing a form W-9, certifying that such Lender is a domestic
corporation, partnership estate or trust. If any form or document referred to in
this Section 2.08 requires the disclosure of information, other than information
necessary to compute the tax payable and information required on the date hereof
by Internal Revenue Service form 1001 or, 4224 or W-8 or W-9 (or the related
certificate described above), that the Lender reasonably considers to be
confidential, the Lender shall give notice thereof to the Administrative Agent
and shall not be obligated to include in such form or document such confidential
information.

                  SECTION 2.09. Sharing of Payments, Etc. If any Lender shall
obtain at any time any payment (whether voluntary, involuntary, through the
exercise of any right of set-off, or otherwise) (a) on account of Obligations
due and payable to such Lender hereunder and under the Notes at such time in
excess of its ratable share (according to the proportion of (i) the amount of
such Obligations due and payable to such Lender at such time to (ii) the
aggregate amount of the Obligations due and payable to all Lenders hereunder and
under the Notes at such time) of payments on account of the Obligations due and
payable to all Lenders hereunder and under the Notes at such time obtained by
all of the Lenders at such time or (b) on account of Obligations owing (but not
due and payable) to such Lender hereunder and under the Notes at such time in
excess of its ratable share (according to the proportion of (i) the amount of
such Obligations owing to such Lender at such time to (ii) the aggregate amount
of the Obligations owing (but not due and payable) to all Lenders hereunder and
under the Notes at such time) of payments on account of the Obligations owing
(but not due and payable) to all Lenders hereunder and under the Notes at such
time obtained by all of the Lenders at such time, such Lender shall forthwith
purchase from the other Lenders such participations in the Obligations due and
payable or owing to them, as the case may be, 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 other
Lender shall be rescinded and each such other Lender shall repay to the
purchasing Lender the purchase price to the extent of such Lender's ratable
share (according to the proportion of (i) the purchase price paid to such Lender
to (ii) the aggregate purchase price paid to all Lenders) of such recovery
together with an amount equal to such Lender's ratable share (according to the
proportion of (i) the amount of such other Lender's required repayment to (ii)
the total amount so recovered from the purchasing Lender) of any interest or
other amount paid or payable by the purchasing Lender in respect of the total
amount so recovered. The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section 2.09 may, to


<PAGE>   26


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.

                  SECTION 2.10. Use of Proceeds. The proceeds of the Series A
Advances and Series B Advances shall be available (and the Borrower agrees that
it shall use such proceeds) solely to purchase the Ericsson Equipment in
accordance with the terms of the Equipment Purchase Agreement for use in (i) the
MTAs of Jacksonville, Florida; Memphis, Tennessee/Jackson, Mississippi; and
Birmingham, Alabama; (ii) the Atlanta MTA; and (iii) the BTA Markets; provided
that the proceeds of the Series B Advances shall be available (and the Borrower
agrees that it shall use such proceeds) for use in any BTA Market only upon the
satisfaction of the conditions precedent set forth in Section 3.05 hereof.

                  SECTION 4.01. Representations and Warranties of the Borrower.
The Borrower represents and warrants as follows:

                  (a) Each Loan Party (i) is a corporation duly organized,
         validly existing and in good standing under the laws of the
         jurisdiction of its incorporation, (ii) is duly qualified and in good
         standing as a foreign corporation in each other jurisdiction in which
         it owns or leases property or in which the conduct of its business

         qualify or be licensed would not have a Material Adverse Effect and
         (iii) has all requisite corporate power and authority (including,
         without limitation, all material governmental licenses, permits and
         other approvals) to own or lease and operate its properties and to

         been validly issued, is fully paid and non-assessable and is owned by
         each of the Operating Subsidiaries in the amounts specified on Schedule

         non-assessable and all of the outstanding capital stock of the

         necessary corporate action, and do not (i) contravene such Loan Party's
         charter or bylaws, (ii) violate any law, rule, regulation, order, writ,

         of its Subsidiaries comply in all material respects with all applicable

         has occurred and is continuing with respect to the Borrower or any of
         its Subsidiaries relating to compliance with any Environmental Laws or
         any release of hazardous materials which, individually or in the
         aggregate, has had or will have a Material Adverse Effect, and no
         circumstances exist that could cause any property of any Loan Party or
         any Subsidiary thereof to be subject to any restrictions on ownership,
         occupancy, use or transferability under any Environmental Law except
         where the failure to so comply would not have a Material Adverse

         party to any indenture, loan or credit agreement or any lease or other

                  (n) The Collateral Documents create a valid first priority

         desirable to perfect and protect such security interest have been duly
         taken. The Loan Parties are the legal and beneficial owners of the

         making of any Advances, nor the application of the proceeds or
         repayment thereof by the Borrower, nor the consummation of the other
         transactions contemplated hereby, will violate any provision of such
         Act or any rule, regulation or order of the Securities and Exchange
         Commission thereunder.

         accurate list of all Material Contracts, showing as of the date hereof
         the parties, subject matter and term thereof. Each such Material
         Contract has been duly authorized, executed and delivered by all
         parties thereto, has not been amended or otherwise modified, is in full
         force and effect and is binding upon and enforceable against all
         parties thereto in accordance with


<PAGE>   34

         its terms, and there exists no default under any Material Contract by
         any party thereto that would have a Material Adverse Effect.

                  (t) No Prospectus as of its date of issue contained any untrue
         statement of a material fact or omitted to state any material fact
         necessary to make the statements therein, in light of the circumstances
         under which they are or were made, not misleading, and the issuance of
         the common stock and units of Powertel as contemplated by the
         Prospectuses complied, in all material respects, with all applicable
         laws, rules, regulations and orders.

         assessment, charge or claim that is being contested in good faith and
         by proper proceedings and as to which appropriate reserves are being
         maintained, unless and until any Lien resulting therefrom attaches to
         its property and becomes enforceable against its other creditors.

                  (c) Compliance with Environmental Laws. Comply, and cause each
         of its Subsidiaries and all lessees and other Persons operating or

         Borrower's charter and bylaws; and provided further that neither the
         Borrower nor any of its Subsidiaries shall be required to preserve any

         the preservation thereof is no longer desirable in the conduct of the
         business of the Borrower or such Subsidiary, as the case may be, and
         that the loss thereof does not cause a Material Adverse Effect.

         confidentiality or other information of a similar type.

                  (g) Keeping of Books. Keep, and cause each of its Subsidiaries

                                   ARTICLE VII

                     THE AGENT AND THE ADMINISTRATIVE AGENT

                  SECTION 7.01. Authorization and Action. Each Lender (in its
capacity as a Lender) hereby appoints and authorizes each of the Agent and the
Administrative Agent to take such action as agent on its behalf and to exercise
such powers and discretion under this Agreement and the other Loan Documents as
are delegated to each of the Agent and the Administrative Agent, respectively,
by the terms hereof and thereof, together with such powers and discretion as are
reasonably incidental thereto. As to any matters not expressly provided for by
the Loan Documents (including, without limitation, enforcement or collection of
the Notes), the Agent and the Administrative Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Required Lenders, and such
instructions shall be binding upon all Lenders and all holders of Notes;
provided, however, that neither the Agent nor the Administrative Agent shall be
required to take any action that exposes the Agent or the Administrative Agent
to personal liability or that is contrary to this Agreement or applicable law.
The Administrative Agent agrees to give to each Lender prompt notice of each
notice given to it by the Borrower pursuant to the terms of this Agreement or
the Collateral Documents, as the case may be.

                  SECTION 7.02. Agent's and Administrative Agent's Reliance,
Etc. None of the Agent, the Administrative Agent or any of their directors,
officers, agents or employees shall be liable for any action taken or omitted to
be taken by them under or in connection with the Loan


<PAGE>   44


Documents, except for their own gross negligence or willful misconduct. Without
limitation of the generality of the foregoing, the Agent and the Administrative
Agent: (a) may treat the payee of any Note as the holder thereof until the
Administrative Agent receives and accepts an Assignment Agreement entered into
by the Lender that is the payee of such Note, as assignor, and an Eligible
Assignee, as assignee, as provided in Section 8.07; (b) may consult with legal
counsel (including counsel for any Loan Party), independent public accountants
and other experts selected by it and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts; (c) makes no warranty or representation to any
Lender and shall not be responsible to any Lender for any statements, warranties
or representations (whether written or oral) made in or in connection with the
Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the
performance or observance of any of the terms, covenants or conditions of any
Loan Document on the part of any Loan Party or to inspect the property
(including the books and records) of any Loan Party; (e) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of, or the perfection or
priority of any lien or security interest created or purported to be created
under or in connection with, any Loan Document or any other instrument or
document furnished pursuant thereto; and (f) shall incur no liability under or
in respect of any Loan Document by acting upon any notice, consent, certificate
or other instrument or writing (which may be by telegram, telecopy or telex)
believed by it to be genuine and signed or sent by the proper party or parties.

                  SECTION 7.03. Agent, Administrative Agent and Their
Affiliates. With respect to their Commitments, the Advances made by each of them
and the Notes issued to each of them, the Agent and the Administrative Agent
shall each have the same rights and powers under the Loan Documents as any other
Lender and may exercise the same as though it were not the Agent or the
Administrative Agent, as applicable; and the term "Lender" shall, unless
otherwise expressly indicated, include both the Agent and the Administrative
Agent, each in its individual capacity. The Agent, the Administrative Agent and
their respective affiliates may generally engage in any kind of business with,
any Loan Party, any of its Subsidiaries and any Person who may do business with
or own securities of any Loan Party or any such Subsidiary, all as if the Agent
and the Administrative Agent were not the Agent and the Administrative Agent,
respectively, and without any duty to account therefor to the Lenders.

                  SECTION 7.04. Lender Credit Decision. Each Lender acknowledges
that it has, independently and without reliance upon the Agent, the
Administrative Agent or any other Lender and based on the financial statements
referred to in Section 4.01 and such other documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Lender also acknowledges that it will, independently and without
reliance upon the Agent, the Administrative Agent or any other Lender and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement.

                  SECTION 7.05. Indemnification of the Agent and the
Administrative Agent. Each Lender severally agrees to indemnify the Agent and
the Administrative Agent (to the extent not promptly reimbursed by the Borrower)
from and against such Lender's ratable share (determined as provided below) of
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever that may be imposed on, incurred by, or asserted against the Agent or
the Administrative Agent in


<PAGE>   45


any way relating to or arising out of the Loan Documents or any action taken or
omitted by the Agent or the Administrative Agent under the Loan Documents;
provided, however, that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Agent's or the
Administrative Agent's gross negligence or willful misconduct. Without
limitation of the foregoing, each Lender agrees to reimburse the Agent and the
Administrative Agent promptly upon demand for its ratable share of any costs and
expenses (including, without limitation, fees and expenses of counsel) payable
by the Borrower under Section 8.04, to the extent that the Agent or the
Administrative Agent is not promptly reimbursed for such costs and expenses by
the Borrower. For purposes of this Section 7.05, the Lenders' respective ratable
shares of any amount shall be determined, at any time, according to the sum of
(a) the aggregate principal amount of the Advances outstanding at such time and
owing to the respective Lenders and (b) the aggregate unused portions of their
respective Commitments at such time. The failure of any Lender to reimburse the
Agent or the Administrative Agent promptly upon demand for its ratable share of
any amount required to be paid by the Lender to the Agent or the Administrative
Agent as provided herein shall not relieve any other Lender of its obligation
hereunder to reimburse the Agent or the Administrative Agent for its ratable
share of such amount, but no Lender shall be responsible for the failure of any
other Lender to reimburse the Agent or the Administrative Agent for such other
Lender's ratable share of such amount. Without prejudice to the survival of any
other agreement of any Lender hereunder, the agreement and obligations of each
Lender contained in this Section 7.05 shall survive the payment in full of
principal, interest and all other amounts payable hereunder and under the other
Loan Documents.

                  SECTION 7.06. Successor Agents and Administrative Agents. The
Agent and the Administrative Agent may resign at any time by giving written
notice thereof to the Lenders and the Borrower, and the Agent or the
Administrative Agent may be removed at any time with or without cause by the
Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right to appoint a successor Agent or Administrative Agent, as
the case may be. If no successor Agent or successor Administrative Agent shall
have been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Agent's or Administrative Agent's
giving of notice of resignation or the Required Lenders' removal of the retiring
Agent or Administrative Agent, then the retiring Agent or Administrative Agent,
as appropriate, may, on behalf of the Lenders, appoint a successor Agent or
Administrative Agent, as appropriate, which shall be a commercial bank organized
under the laws of the United States or of any State thereof and having a
combined capital and surplus of at least $250,000,000. Upon the acceptance of
any appointment as Agent hereunder by a successor Agent or as Administrative
Agent hereunder by a successor Administrative Agent, and, in the case of a
successor Agent, upon the execution and filing or recording of such financing
statements, or amendments thereto, and such other instruments or notices, as may
be necessary or desirable, or as the Required Lenders may request, in order to
continue the perfection of the Liens granted or purported to be granted by the
Collateral Documents, such successor Agent or Administrative Agent, as the case
may be, shall succeed to and become vested with all the rights, powers,
discretion, privileges and duties of the retiring Agent or Administrative Agent,
as applicable, and the retiring Agent or Administrative Agent shall be
discharged from its duties and obligations under the Loan Documents. After any
retiring Agent's or Administrative Agent's resignation or removal hereunder as
Agent or Administrative Agent, the provisions of this Article VII shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent or Administrative Agent, as the case may be, under this Agreement.

duties of the Administrative Agent or the Agent, as the case may be, under this
Agreement, the Notes or the Collateral Documents. The Administrative Agent shall
be authorized to modify Schedules 2.01(a) and 2.01(b) in the event of the
assignment of any Commitment hereunder.

                  SECTION 8.02. Notices, Etc. All notices and other

waiver of any provision of this Agreement or the


<PAGE>   47


Notes or of any Exhibit hereto to be executed and delivered hereunder shall be
effective as delivery of a manually executed counterpart thereof.

                  SECTION 8.03. No Waiver; Remedies. No failure on the part of
any Lender, the Agent or the Administrative Agent to exercise, and no delay in
exercising, any right hereunder or under any Note shall operate as a waiver
thereof; nor shall any single or partial exercise of any such right preclude any
other or further exercise thereof or the exercise of any other right. The
remedies herein provided are cumulative and not exclusive of any remedies
provided by law.

                  SECTION 8.04. Costs and Expenses. (a) The Borrower agrees to
pay on demand (i) all costs and expenses of the Agent and the Administrative
Agent in connection with the preparation, execution and delivery of the Loan
Documents up to an amount not to exceed the amount separately agreed prior to
the date hereof, (ii) all costs and expenses in connection with filing,
recording and the granting and perfection of, the security interests in the
Collateral, (iii) the reasonable fees and expenses of counsel for each of the
Agent and the Administrative Agent with respect thereto, with respect to
advising each of the Agent and the Administrative Agent as to its rights and
responsibilities, or the perfection, protection or preservation of rights or
interests, under the Loan Documents, with respect to negotiations with any Loan
Party or with other creditors of any Loan Party or any of its Subsidiaries
arising out of any Default or any events or circumstances that may give rise to
a Default and with respect to presenting claims in or otherwise participating in
or monitoring any bankruptcy, insolvency or other similar proceeding involving
creditors' rights generally and any proceeding ancillary thereto) and (iv) all
costs and expenses of the Agent, the Administrative Agent and the Lenders in
connection with the enforcement of the Loan Documents, whether in any action,
suit or litigation, any bankruptcy, insolvency or other similar proceeding
affecting creditors' rights generally (including, without limitation, the
reasonable fees and expenses of counsel for the Agent, the Administrative Agent
and each Lender with respect thereto).

                  (b) The Borrower agrees to indemnify and hold harmless the
Agent, the Administrative Agent and each Lender and each of their Affiliates and
their officers, directors, employees, agents and advisors (each, an "Indemnified
Party") from and against any and all claims, damages, losses, liabilities and
expenses (including, without limitation, reasonable fees and expenses of
counsel) that may be incurred by or asserted or awarded against any Indemnified
Party, in each case arising out of or in connection with or by reason of, or in
connection with the preparation for a defense of, any investigation, litigation
or proceeding arising out of, related to or in connection with this Agreement,
the actual or proposed use of the proceeds of the Advances, the Loan Documents
or any of the transactions contemplated thereby, in each case whether or not
such investigation, litigation or proceeding is brought by any Loan Party, its
directors, shareholders or creditors or an Indemnified Party or any Indemnified
Party is otherwise a party thereto and whether or not the transactions
contemplated hereby are consummated, except to the extent such claim, damage,
loss, liability or expense is found in a final, non-appealable judgment by a
court of competent jurisdiction to have resulted from such Indemnified Party's
gross negligence or willful misconduct.

                  (c) Without prejudice to the survival of any other agreement
of any Loan Party hereunder or under any other Loan Document, the agreements and
obligations of the Borrower contained in Section 2.06 and this Section 8.04
shall survive the payment in full of


<PAGE>   48


principal, interest and all other amounts payable hereunder and under any of the
other Loan Documents.

                  SECTION 8.05. Right of Set-off. Upon (a) the occurrence and
during the continuance of any Event of Default and (b) the making of the request
or the granting of the consent specified by Section 6.01 to authorize the
Administrative Agent to declare the Notes due and payable pursuant to the
provisions of Section 6.01, each Lender and each of its respective Affiliates is
hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off and otherwise apply any and all deposits (general
or special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by such Lender or such Affiliate to or for the
credit or the account of the Borrower against any and all of the Obligations of
the Borrower now or hereafter existing under this Agreement and the Note or
Notes (if any) held by such Lender, irrespective of whether such Lender shall
have made any demand under this Agreement or such Note or Notes and although
such obligations may be unmatured. Each Lender agrees promptly to notify the
Borrower after any such set-off and application; provided, however, that the
failure to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender and its respective Affiliates under this
Section are in addition to other rights and remedies (including, without
limitation, other rights of set-off) that such Lender and its respective
Affiliates may have.

                  SECTION 8.06. Binding Effect. This Agreement shall become
effective when it shall have been executed by the Borrower, the Agent and the
Administrative Agent and when the Agent shall have been notified by each Initial
Lender that such Initial Lender has executed it and thereafter shall be binding
upon and inure to the benefit of the Borrower, the Agent, the Administrative
Agent and each Lender and their respective successors and assigns, except that
the Borrower shall not have the right to assign its rights hereunder or any
interest herein without the prior written consent of the Lenders.

                  SECTION 8.07. Assignments and Participations. (a) Each Lender
may assign to one or more Persons all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitment, the Advances owing to it and the Note or Notes held by it);
provided, however, that (i) each such assignment shall be of a constant, and not
a varying, percentage of all rights and obligations under and in respect of one
or more Facilities, (ii) except in the case of an assignment to a Person that,
immediately prior to such assignment, was a Lender or an assignment of all of a
Lender's rights and obligations under this Agreement, the amount of the
Commitments of the assigning Lender being assigned pursuant to each such
assignment (determined as of the date of the Assignment Agreement with respect
to such assignment) shall in no event be less than $5,000,000; (iii) each such
assignment shall be to an Eligible Assignee, and (iv) the parties to each such
assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording in the Register, an Assignment Agreement, together with
(x) any Note subject to such assignment and (y) a processing and recordation fee
of $3,500 (provided, however, that no such fee shall be required to be paid in
connection with the processing and recordation of any of the first six
Assignment Agreements pursuant to which all or part of a Lender's Series B
Commitment and/or any Series B Advances owing to any Lender are assigned). Upon
such execution, delivery, acceptance and recording, from and after the effective
date specified in each Assignment Agreement, (x) the assignee thereunder shall
be a party hereto and, to the extent that rights and obligations hereunder have
been assigned to it pursuant to such Assignment Agreement, have the rights and


<PAGE>   49


obligations of a Lender hereunder and (y) the Lender assignor thereunder shall,
to the extent that rights and obligations hereunder have been assigned by it
pursuant to such Assignment Agreement, relinquish its rights and be released
from its obligations under this Agreement (and, in the case of an Assignment
Agreement covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such Lender shall cease to be a party
hereto).

                  (b) By executing and delivering an Assignment Agreement, the
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) other than as provided
in such Assignment Agreement, such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of, or the perfection or priority of any lien or security interest created
or purported to be created under or in connection with, this Agreement or any
other instrument or document furnished pursuant hereto; (ii) such assigning
Lender makes no representation or warranty and assumes no responsibility with
respect to the financial condition of any Loan Party or the performance or
observance by any Loan Party of any of its obligations under this Agreement or
any other instrument or document furnished pursuant hereto; (iii) such assignee
confirms that it has received a copy of this Agreement, together with copies of
the financial statements referred to in Section 4.01 and such other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment Agreement; (iv) such assignee will,
independently and without reliance upon the Agent, the Administrative Agent,
such assigning Lender or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement; (v) such
assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints
and authorizes each of the Agent and the Administrative Agent to take such
action as agent on its behalf and to exercise such powers and discretion under
this Agreement as are delegated to the Agent and the Administrative Agent by the
terms hereof, together with such powers and discretion as are reasonably
incidental thereto; and (vii) such assignee agrees that it will perform in
accordance with their terms all of the obligations that by the terms of this
Agreement are required to be performed by it as a Lender.

                  (c) The Administrative Agent shall maintain at its address
referred to in Section 8.02 a copy of each Assignment Agreement delivered to and
accepted by it and a register for the recordation of the names and addresses of
the Lenders and the Commitment under each Facility of, and principal amount of
the Advances owing under each Facility to, each Lender from time to time (the
"Register"). The entries in the Register shall be conclusive and binding for all
purposes, absent manifest error, and the Borrower, the Agent, the Administrative
Agent and the Lenders may treat each Person whose name is recorded in the
Register as a Lender hereunder for all purposes of this Agreement. The Register
shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

                  (d) Upon its receipt of an Assignment Agreement executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note or Notes subject to such assignment, the Administrative
Agent shall, if such Assignment Agreement has been completed and is in
substantially the form of Exhibit G hereto, (i) accept such


<PAGE>   50


Assignment Agreement, (ii) record the information contained therein in the
Register, (iii) give prompt notice thereof to the Borrower, and (iv) give prompt
notice to the Borrower of the request, if any, by such assignee and/or by the
assigning Lender in respect of the Commitment retained by it under any Facility,
for the execution of a new Note or Notes pursuant to Section 2.03(b). Within
five Business Days after its receipt of the notice referred to in clause (iv)
above, the Borrower, at its own expense, shall execute and deliver to the
Administrative Agent (in exchange for the surrendered Note(s), if any) a new
Note or Notes, as applicable, (x) to the order of such assignee, in an amount
equal to the Commitment assumed by it under a Facility pursuant to such
Assignment Agreement, and/or (y) to the order of the assigning Lender, in an
amount equal to the Commitment retained by it under such Facility. Any new Note
or Notes issued to any Lender shall be in an aggregate principal amount equal to
the aggregate principal amount of the Commitment assumed or retained by such
Lender, shall be dated the effective date of such Assignment Agreement and shall
otherwise be in substantially the form of Exhibit A hereto.

                  (e) Each Lender may sell participations to one or more banks
or other entities (other than the Borrower or any of its Affiliates) in or to
all or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Commitment, the Advances owing to it
and the Note or Notes held by it); provided, however, that (i) such Lender's
obligations under this Agreement (including, without limitation, its Commitments
to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (iii) such Lender shall remain the holder of any such Note for all
purposes of this Agreement, (iv) the Borrower, the Agent, the Administrative
Agent and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement, (v) no such participation shall result in any increased costs to the
Borrower and (vi) no participant under any such participation shall have any
right to approve any amendment or waiver of any provision of this Agreement or
any Note, or any consent to any departure by the Borrower therefrom, except to
the extent that such amendment, waiver or consent would reduce the principal of,
or interest on, the Notes or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation, or postpone any date
fixed for any payment of principal of, or interest on, the Notes or any fees or
other amounts payable hereunder, in each case to the extent subject to such
participation.

                  (f) Any Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
8.07, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrower furnished to such Lender
by or on behalf of the Borrower; provided that, prior to any such disclosure,
the assignee or participant or proposed assignee or participant shall agree to
be bound by the confidentiality provisions set forth in Section 8.12 of this
Agreement.

                  (g) Notwithstanding any other provision set forth in this
Agreement, any Lender may at any time create a security interest in all or any
portion of its rights under this Agreement (including, without limitation, the
Advances owing to it and the Note held by it) in favor of any Federal Reserve
Bank in accordance with Regulation A of the Board of Governors of the Federal
Reserve System.

                  SECTION 8.08. Execution in Counterparts. This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of


<PAGE>   51


which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement. Delivery of an executed
counterpart of a signature page to this Agreement by telecopier shall be
effective as delivery of a manually executed counterpart of this Agreement.

                  SECTION 8.09. Jurisdiction, Etc. (a) The Borrower hereto
hereby irrevocably and unconditionally submits, for itself and its property, to
the nonexclusive jurisdiction of any New York State court or federal court of
the United States of America sitting in New York City, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement or any of the other Loan Documents to which it is a party, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in any such New York State
court or, to the extent permitted by law, in such federal court. The Borrower
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that any party may otherwise have to bring any action or proceeding
relating to this Agreement or any of the other Loan Documents in the courts of
any jurisdiction.

                  (b) The Borrower hereto irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Agreement or any of the
other Loan Documents to which it is a party in any New York State or federal
court. The Borrower hereto hereby irrevocably waives, to the fullest extent
permitted by law, the defense of an inconvenient forum to the maintenance of
such action or proceeding in any such court.

                  SECTION 8.10. Governing Law. This Agreement and the Notes
shall be governed by, and construed in accordance with, the laws of the State of
New York.

                  SECTION 8.11. Waiver of Jury Trial. Each of the Borrower and
the Lenders irrevocably waives all right to trial by jury in any action,
proceeding or counterclaim (whether based on contract, tort or otherwise)
arising out of or relating to any of the Loan Documents, the Advances or the
actions of the Agent, the Administrative Agent or any Lender in the negotiation,
administration, performance or enforcement thereof.

                  SECTION 8.12. Confidentiality. None of the Agent, the
Administrative Agent, the Lenders or the Borrower shall disclose the terms of
this Agreement, the other Loan Documents or the transactions contemplated
thereby to any Person without the consent of the other parties hereto, other
than (a) to the Agent's, the Administrative Agent's, the Lender's or the
Borrower's Affiliates and their officers, directors, employees, agents and
advisors and to actual or prospective Eligible Assignees and participants, and
then only on a confidential basis, (b) as required by any law, rule or
regulation or judicial process and (c) as requested or required by any state,
federal or foreign authority.

                  SECTION 8.13. Modification of Financial Tests. Prior to

financial tests consisting of (a) a ratio of EBITDA to debt service of Powertel
and its Subsidiaries, (b) a ratio of Debt to EBITDA of


<PAGE>   52


Powertel and its Subsidiaries and (c) a level of maximum capital expenditure, in
each case, based upon the business plan for 1998 delivered by the Borrower to
the Lenders in accordance with Section 5.03(d).
