                                   AGREEMENT

         THIS AGREEMENT is made by and between BellSouth Telecommunications,
Inc. ("BellSouth"), a Georgia corporation, and Powertel, Inc. ("Powertel"), a
Delaware corporation, together with and on behalf of certain of its direct and
indirect, wholly owned and partially owned wireless operating subsidiaries
(Powertel and each such subsidiary  a "Carrier" hereunder) and shall be deemed
effective as of April 1, 1997 (the "Effective Date").  Powertel hereby
represents that it has the authority to bind each Carrier. This Agreement
constitutes an agreement between (i) BellSouth, on the one hand and (ii) each
Carrier, on the other hand.  BellSouth and each Carrier are referred to herein
as a "party" and collectively as "parties."

                                   WITNESSETH

         WHEREAS, The Telecommunications Act of 1996, Public Law 104-104 (the
"Act"), was signed into law on February 8, 1996;

         WHEREAS, the Act, among other things, places certain duties and
obligations upon, and grants certain rights to, telecommunications carriers;

         WHEREAS, BellSouth is a Telecommunications Carrier, and an Incumbent
Local Exchange Carrier ("ILEC"), authorized to provide telecommunications
services in the states of Alabama, Florida, Georgia, Kentucky, Louisiana,
Mississippi, North Carolina, South Carolina, and Tennessee;

         WHEREAS, Carrier is a Commercial Mobile Radio Service ("CMRS")
provider licensed by the Federal Communications Commission ("FCC") to provide

Kentucky, Louisiana, Mississippi, South Carolina and Tennessee;

         WHEREAS, Carrier is licensed to do business in such states and
operates a CMRS network that is interconnected, or will be interconnected with,
the BellSouth network ;

         WHEREAS, under the FCC Order dated August 8, 1996 and published in the
Federal Register on August 29, 1996 pertaining to interconnection, unbundling,
and resale (the "Order"), the FCC ordered that ILECs negotiate with CMRS
providers for such services pursuant to Sections 251 and 252 of the Act;
however, certain of the FCC rules, appended to, and made part of, the Order
have been stayed by the United States Court of Appeals for the Eighth Circuit
pending further judicial review;
<PAGE>   2


         WHEREAS, BellSouth is entering into this Agreement in order, among
other things, to fulfill its obligation to establish mutual compensation
arrangements for the transport and termination of telecommunications;

         NOW THEREFORE, in consideration of the mutual agreements contained
herein, the parties agree as follows:

I.       DEFINITIONS. For purposes of this Agreement, the following capitalized
terms shall have the indicated meanings unless the provision in which any such
term appears states otherwise.  Terms that appear herein (whether or not
capitalized) that are not defined herein shall have the meaning set forth in
the Act, or in the Order, or shall have the meanings ascribed to them in their
customary usage in the telecommunications industry as of the Effective Date.

         A.  "COMMISSION" means the appropriate regulatory agency in each of
the states in which Carrier is licensed to do business in BellSouth's region.

         B.  "INTERMEDIARY FUNCTION" means the delivery, pursuant to an
appropriate agreement or Commission directive, of telecommunications traffic to
or from a Local Exchange Carrier ("LEC") other than BellSouth, an ALEC, or
another telecommunications carrier, such as a CMRS provider other than Carrier,
through the network of BellSouth or Carrier from or to an end user of BellSouth
or Carrier.

         C.  "LOCAL TRAFFIC" means for purposes of reciprocal compensation and
the obligation of the parties to provide Local Interconnection (1) any
telephone call that originates on the network of Carrier within a Major Trading
Area ("MTA") and terminates on the network of BellSouth in the same MTA and
within the Local Access and Transport Area ("LATA") in which the call is handed
off from Carrier to BellSouth and (2) any telephone call that originates on the
network of BellSouth that is handed off to Carrier in the same LATA in which
the call originates and terminates on the network of Carrier in the MTA in
which the call is handed off from BellSouth to the Carrier.  The exchange of
traffic on BellSouth's interLATA EAS routes shall be treated as Local Traffic.
EAS routes are those exchanges within an exchange's Basic Local Calling Area,
as defined in Section A3 of BellSouth's General Subscriber Services Tariff.

         D.  "LOCAL INTERCONNECTION" means the delivery of Local Traffic to be
terminated on each party's local network so that end users of a party have the
ability to reach end users of another party without the use of any access code
or substantial delay in the processing of the call.

         E.  "PERCENT OF INTERSTATE USAGE" OR "PIU" means a factor to be
applied to terminating access services minutes of use (for termination of Toll
Traffic) to obtain those minutes that should be rated as interstate access
services minutes of use.  The numerator includes all interstate
"nonintermediary" minutes of use, less any interstate minutes of use for
Terminating Party Pays services, such as 800 Services.  The



                                      2
<PAGE>   3

denominator includes all "nonintermediary" access minutes of use of Toll
Traffic less all minutes attributable to terminating party pays services.

         F.  "PERCENT LOCAL USAGE" OR "PLU" means a factor to be applied to
terminating minutes of use.  The numerator shall include all Local Traffic
minutes of use.  The denominator is the total minutes of use including Local
Traffic and Toll Traffic.

         G.  "TOLL TRAFFIC" means all traffic that is not Local Traffic or
access services, as described in Section VI.F of this Agreement.

         H.  "MOBILE SWITCHING CENTER" OR "MSC" means a mobile switching center
of Carrier.

II.      PURPOSE; FURTHER NEGOTIATIONS; APPLICATION OF TARIFFS

         A.      The parties enter this Agreement to memorialize their
agreement with respect to certain matters concerning Local Interconnection as a
result of their negotiations pursuant to Sections 251 and 252 of the Act.  With
respect to any facility, feature, function, service, or other arrangement
concerning Local Interconnection or any other matter subject to negotiation
pursuant to Sections 251 and 252 of the Act between the parties that has not
been agreed upon by the parties and memorialized herein, (a) the parties shall
conduct further negotiations pursuant to Sections 251 and 252 of the Act upon a
written request therefor by Carrier, and (b) Carrier reserves any rights it
might have under Section 332 of the Communications Act of 1934, 47 U.S.C.
Section 332, as amended.

         B.      Any facility, feature, function, or service in use or
available for use between BellSouth and any party as of the Effective Date that
is not expressly governed by this Agreement shall continue to be governed by
such applicable tariff, agreement, or other arrangement, if any, in effect as
of the Effective Date, as may be modified from time to time pursuant to
applicable rules of the Commission.  In the event of a conflict between any
provision of this Agreement and any provision of an applicable tariff, the
Agreement shall always control.

         C.      It is the parties' intent that this Agreement be consistent
with all applicable federal, state, and local statutes, rules, and regulations
in effect as of the Effective Date, including, but not limited to, the Act and
the Order.

III.     TERM OF THE AGREEMENT

         A.      This Agreement shall be in full force and effect for a period
of two years from the Effective Date.  The Agreement shall be automatically
renewed for an additional term of six months following such initial two-year
term and for successive six-month terms thereafter following each preceding
six-month renewal term unless a party





                                       3
<PAGE>   4

provides to the other a written notice of termination at least sixty days prior
to the last day of the initial two-year term or any subsequent six-month
renewal term, as the case may be.

         B.      In the event BellSouth or Carrier receives from the other a
notice of termination pursuant to paragraph A of this Section, Powertel may
within 30 days thereof send to BellSouth a written request to renegotiate this
Agreement pursuant to Sections 251 and 252 of the Act, in which case this
Agreement shall not be terminated, but shall continue in full force and effect,
unless and until a substitute agreement between the parties with respect to the
matters governed herein takes effect.

         C.      Notwithstanding the foregoing, the parties may terminate this
Agreement at any time upon their written mutual consent.

IV.      LOCAL INTERCONNECTION

         The delivery of Local Traffic between the parties shall be reciprocal
and compensation will be mutual.  Each party will pay the other for
transporting and terminating its respective Local Traffic on the other's
network at the Local Interconnection rates set forth in Attachment B-1, by this
reference incorporated herein.  The amount that each party shall pay to the
other for the delivery of Local Traffic shall be calculated by multiplying the
applicable rate in Attachment B-1 for each type of call by the total minutes of
use each month for each such type of call. The minutes of use or portion
thereof for each call, as the case may be, will be accumulated for the monthly
billing period and the total of such minutes of use for the entire month
rounded to the nearest minute.  The usage charges will be billed based on the
rounded total monthly minutes. The charges for Local Interconnection shall be
billed monthly and payable monthly. For undisputed bill amounts, late payment
fees, not to exceed 1% per month after the due date, may be assessed if
interconnection charges are not paid within 30 days of the due date of the
monthly bill.

V.       MODIFICATION OF RATES

         A.      (1)  The "Interim LATA-wide Additive" reflected in Attachment
B-1 shall be adjusted, retroactively to the Effective Date, based on the Final
LATA-wide Additive either determined by (a) further agreement as described in
subsection (B) hereof or (b) a final order (including the exhaustion of all
appeals, if any) of the Commission or the FCC, as the case may be, provided
that such a final order meets the criteria contained in subsection (C) hereof.
The "LATA-wide Additive" is intended to compensate BellSouth for any additional
transport and other costs associated with transporting and terminating Local
Traffic throughout a LATA instead of only within local calling areas, including
EAS routes, as defined by the Commission as of the Effective Date. As of the
Effective Date, the parties disagree as to the proper amount for the LATA-Wide





                                       4
<PAGE>   5

Additive.  The Interim LATA-wide Additive of $.0025 per minute that is included
in the Type 1, 2A, and 2A-CCS7 rates set forth in Attachment B-1 was arrived at
through negotiation and compromise and is without prejudice to either party's
position as to what additional or lesser charges, if any, should apply.  As
such, the fact that the parties have agreed to this amount as the Interim
LATA-wide Additive shall have no probative value in any Commission or FCC
proceedings, as the case may be, to determine the Final LATA-wide Additive
described in this section.

                 (2)      This adjustment, or "true-up," will consist of:

                 i.       Calculating the difference between the Final
LATA-wide Additive and the Interim LATA-wide Additive, as reflected in
Attachment B-1 of this Agreement. The difference is referred to as the
"LATA-wide Additive Adjustment";

                 ii.      Multiplying the "LATA-wide Additive Adjustment" by
all minutes of use for which the Interim LATA-wide was applied and billed by
the parties since the Effective Date, the product of which shall be the
"True-up Adjustment";

                 iii.     The parties will reciprocally compensate each other
in an amount equal to the "True-up Adjustment".

         B.      The parties may continue to negotiate after the Effective Date
in an effort to obtain a Final LATA-wide Additive.  Powertel may send BellSouth
a written request for negotiation of a Final LATA-wide Additive pursuant to
Sections 251 and 252 of the Act, no sooner than seventy-five (75) days after
the Effective Date.  Following such request, the parties shall negotiate, and
if necessary arbitrate, the Final LATA-wide Additive pursuant to, and in
accordance with, the Act.

         C.      Any final order that forms the basis of a "true-up" under this
Agreement shall meet the following criteria:

                 1.       It shall be a proceeding to which BellSouth and
Carrier are entitled to be full parties and have had an opportunity to
participate in;

                 2.       It shall apply the provisions of the Act, including
but not limited to Section 252(d) and all effective implementing rules and
regulations, provided that the Act and such regulations are in effect at the
time of the final order; and

                 3.       It shall include as an issue any additional transport
and other costs associated with transporting and terminating Local Traffic
throughout a LATA instead of only within local calling areas, including EAS
routes, as defined by the Commission as of the Effective Date.

VI.      METHODS OF INTERCONNECTION

         A.      (1)      The parties agree that there are three appropriate
methods of interconnecting facilities: (a) virtual collocation where physical
collocation is not practical for technical reasons or because of space
limitations; (b) physical collocation; and (c) interconnection at any
technically feasible point via purchase of facilities from either party by the
other party.  The rates and charges for collocation shall be as set forth in
Attachment C-13, incorporated herein by this reference, or as otherwise agreed
upon by the parties.  Facilities for interconnection that are not purchased
pursuant to an agreement between the parties may be purchased by Carrier at the
rates, terms and conditions set forth in BellSouth's intrastate Switched Access
(Section E6) or Special Access (Section E7) services tariff. The
interconnection of facilities shall be pursuant to the forms of interconnection
(for example, Type 1, Type 2A and Type 2B) described in BellSouth's General
Subscriber Services Tariff, Section A35; provided, however, that such
interconnection arrangements shall be provided at the rates, terms and
conditions set forth in this Agreement.

                 (2)      Local Interconnection shall be provided at a level of
quality at least equal to that which each party provides to itself, an
Affiliate, or any other telecommunications carrier, except that, upon request,
a different level of quality may be provided to the extent technically feasible
and subject to the negotiation of acceptable provisions and compensation
arrangements.  All interconnection facilities shall meet the applicable
telecommunications industry standards of engineering, design, and operation, as
the case may be, for LEC-CMRS interconnection in effect from time to time.

         B.      The parties agree to accept and provide any of the preceding
methods of interconnection.  Reciprocal connectivity shall be established to at
least one BellSouth access tandem within every LATA that Carrier desires to
serve, or Carrier may elect to interconnect directly at the end office for
delivery of traffic to end users served by that end office.  Such
interconnecting facilities shall conform, at a minimum, to the
telecommunications industry standard of DS-1 pursuant to Bellcore Standard No.
TR-NWT-00499.  Signal transfer point, Signaling System 7 ("SS7") connectivity
is required at each interconnection point after Carrier implements SS7
capability within its own network.  BellSouth will provide out-of-band
signaling using Common Channel Signaling Access Capability where technically
and economically feasible, in accordance with the technical specifications set
forth in the BellSouth Guidelines to Technical Publication, TR-TSV-000905.  The
parties' facilities shall (i) provide the necessary on-hook, off-hook answer
and disconnect supervision, (ii) hand off calling party number ID when
technically feasible, and (iii) honor privacy codes when sent and permitted
line blocking requests.

         C.      Nothing herein shall prevent Carrier from utilizing
collocation facilities, purchased from the appropriate tariffs, for Local
Interconnection.





                                       6
<PAGE>   7

         D.      The parties agree to establish trunk groups from the
interconnecting facilities of subsection (A) of this section such that each
party provides a reciprocal of each trunk group established by the other party.
Notwithstanding the foregoing, each party may construct its network, including
the interconnecting facilities, to achieve optimum cost effectiveness and
network efficiency.  Unless otherwise agreed, BellSouth will provide or bear
the cost of all trunk groups for the delivery of traffic from BellSouth to
Carrier's MSCs within BellSouth's service territory, and Carrier will provide
or bear the cost of all trunk groups for the delivery of traffic from Carrier
to each BellSouth access tandem and end office at which the parties
interconnect.  In the event one party interconnects to the other via the
purchase of facilities from the other party, the parties shall negotiate a rate
for such interconnection facilities if an intrastate tariff, as amended from
time to time, does not otherwise apply.  In the event the parties agree to use
any two-way interconnection facilities in lieu of separate one-way facilities,
the appropriate charges for such facilities shall be divided on a pro rata
basis reflecting the percentage of traffic that terminates on the network of
each party.

         E.      The parties agree to use an auditable PLU factor as a method
for determining the amount of traffic that is Local Traffic.

         F.      When the parties provide an access service connection between
an interexchange carrier ("IXC") and each other, each party will provide its
own access services to the IXC.  Each party will bill its own access services
rates to the IXC.

         G.      INTENTIONALLY DELETED

         H.      The ordering and provision of all facilities or services
purchased from BellSouth by Carrier shall be as set forth in the BellSouth
Telecommunications Wireless Customer Guide, as amended from time to time. The
ordering and provisioning of facilities or services by a party, including, but
not limited to, installation, testing, maintenance, repair, and disaster
recovery, shall be provided at a level of quality and care at least equal to
that which it provides to itself, an affiliate, or any other telecommunications
carrier unless Carrier and BellSouth specifically negotiate a different level
of quality or care.

         I.      BellSouth shall endeavor to provide by December 31, 1997 to
Carrier an Electronic Interface (EI) for transferring and receiving orders,
confirmations, completion notices, and other provisioning data, materials and
documents.  This EI shall be administered through a gateway that will serve as
a single point of contact for the transmission of such data from Carrier to
BellSouth, and from BellSouth to Carrier.  The requirements and implementation
of such a data transfer system are subject to future agreement by Carrier and
BellSouth.

         J.      Upon request, the parties shall conduct further negotiations
pursuant to Sections 251 and 252 of the Act regarding the provision of services
described in this Section and nothing in this Agreement shall prohibit, or
shall be construed to prohibit, such negotiations or any arbitration arising
therefrom, if necessary, provided that





                                       7
<PAGE>   8

neither Powertel nor Carrier collectively may make more than one such request
for negotiations with respect to the services described in this section in any
calendar year during which the Agreement is in effect.

           K.       The parties acknowledge that the issues of performance
criteria and remedies for noncompliance related to Local Interconnection remain
unresolved as of the Effective Date. Upon Carrier's written request, the
parties will continue to negotiate these issues in good faith after the
Effective Date, taking into account any relevant Commission decisions,
arbitrations, and other determinations. In the event the parties are unable to
reach agreement on these unresolved issues by the seventy-fifth (75) day
following the Effective Date, then, in addition to all other available
remedies, either party may seek arbitration or other resolution thereof from
the Commission to the extent permitted under sections 251 and 252 of the Act.

VII.     INTRALATA AND INTERLATA TOLL TRAFFIC INTERCONNECTION

         A.      For originating and terminating intrastate or interstate Toll
Traffic, each party shall pay the other at BellSouth's intrastate or
interstate, as appropriate, switched network access service rate elements on a
per minute of use basis.  Said rate elements shall be as set out in BellSouth's
Intrastate Access Services Tariff or BellSouth's Interstate Access Services
Tariff as those Tariffs may be amended from time to time during the term of
this Agreement.  The appropriate charges will be determined by the routing of
the call. The terminating switched access rates may change during the term of
this Agreement and the appropriate rate shall be the rate in effect when the
Toll Traffic is terminated.

         B.      INTENTIONALLY DELETED

         C.      Each party shall compensate the other, pursuant to the
appropriate originating switched access charges, including the database query
charge, for the origination of 800 traffic terminated to the other party.

         D.      INTENTIONALLY DELETED

         E.      INTENTIONALLY DELETED

         F.      INTENTIONALLY DELETED

         G       This Agreement is intended to govern the interconnection of
traffic to and from the parties' networks only. Toll Traffic originated by a
party to this Agreement and delivered to the other party for termination to the
network of a nonparty telecommunications carrier ("Nonparty Carrier") may be
delivered only with the consent of such Nonparty Carrier or pursuant to
Commission directive. If a Nonparty Carrier objects to the delivery of such
Toll Traffic, then either party to this Agreement may request direction from
the Commission.  If a Nonparty Carrier consents, then the party





                                       8
<PAGE>   9

performing the intermediary function will bill the other party and the other
party shall pay a $.002 per minute intermediary charge in addition to any
charges that the party performing the intermediary function may be obligated to
pay to the Nonparty Carrier (collectively called "Toll Intermediary Charges").
The parties agree that the charges that the party performing the intermediary
function may be obligated to pay to the Nonparty Carrier may change during the
term of this Agreement and that the appropriate rate shall be the rate in
effect when the traffic is terminated.

VIII.    PROVISION OF UNBUNDLED ELEMENTS

         At any time after the Effective Date, pursuant to Sections 251 and 252
of the Act, upon request by Carrier, the parties shall negotiate for
BellSouth's provision of unbundled network elements, as provided in Section II
of this Agreement.

IX.      ACCESS TO POLES, DUCTS, CONDUITS, AND RIGHTS OF WAY

         At any time after the Effective Date, pursuant to Sections 251 and 252
of the Act, upon request by Carrier, the parties shall negotiate for
BellSouth's provision of access to poles, ducts, conduits, and rights of way,
as provided in Section II of this Agreement.

X.       ACCESS TO 911/E911 EMERGENCY NETWORK

         A. BellSouth and Carrier recognize that 911 and E911 services were
designed and implemented primarily as methods of providing emergency services
to fixed location subscribers. While BellSouth and Carrier recognize the need
to provide "911-like" service to mobile subscribers, both parties recognize
that current technological restrictions prevent an exact duplication of the
services provided to fixed location customers. BellSouth agrees to route
"911-like" calls received from Carrier to the emergency agency designated by
Carrier for such calls. Carrier agrees that it shall bear the cost of
facilities it uses to deliver such "911-like" calls to BellSouth's network and
to provide to BellSouth the information required by applicable statutes or
regulations governing routing of 911 calls from CMRS subscribers so that each
call may be properly routed.

         B. BellSouth and Carrier recognize that the technology and regulatory
requirements for the provision of "911-like" service by CMRS carriers are
evolving and agree to modify or supplement the foregoing in order to
incorporate technically feasible improvements that Carrier desires to implement
or to permit Carrier to comply with applicable regulatory requirements,
provided that Carrier shall reimburse BellSouth for the incremental costs of
any such technological modification or supplement beyond the cost of an
equivalent, or the most similar, technology at the time accepted in the
telecommunications industry.

         C. Upon request, the parties shall conduct further negotiations 
pursuant to





                                       9
<PAGE>   10

Sections 251 and 252 of the Act regarding the provision of services described
in this Section and nothing in this Agreement shall prohibit, or shall be
construed to prohibit, such negotiations or any arbitration arising therefrom,
if necessary, provided that neither Powertel nor Carrier collectively may make
more than one such request for negotiations with respect to the services
described in this section in any calendar year during which the Agreement is in
effect.

XI.     INTENTIONALLY DELETED

XII.    INTENTIONALLY DELETED

XIII.   ACCESS TO TELEPHONE NUMBERS

         A.      BellSouth, during any period in which it serves as a North
American Numbering Plan administrator for its territory, shall ensure that
Carrier has nondiscriminatory access to telephone numbers for assignment to its
telephone exchange service customers.  BellSouth shall provide numbering
resources pursuant to the Bellcore Guidelines Regarding Number Assignment and
shall provide such resources on terms no less favorable than those which
BellSouth provides to itself, its subsidiaries or Affiliates, or any other
telecommunication carriers.  Carrier agrees that it will complete the NXX code
application in accordance with Industry Carriers Compatibility Forum, Central
Office Code Assignment Guidelines, ICCF 93-0729-010.  Except for Type 1 DID
numbers, this service will be at no charge.

         B.      If during the term of this Agreement BellSouth ceases to be
the North American Numbering Plan administrator, the parties agree to comply
with the guidelines, plan, or rules adopted pursuant to 47 U.S.C. Section
251(e).

XIV.     ACCESS TO SIGNALING AND SIGNALING DATABASES

         A.      BellSouth will offer to Carrier use of its signaling network
and signaling databases on an unbundled basis at BellSouth's published tariffed
rates or at unbundled rates that may be available through non-tariffed
arrangements except as provided in subsection C below.  Signaling functionality
will be available with both A-link and B-link connectivity.

         B.      BellSouth agrees to input the NXXs assigned to Carrier into
the Local Exchange Routing Guide ("LERG").

         C.       Where interconnection is via B-link connections, charges for
the SS7 interconnection elements are as follows: 1) Port Charge - BellSouth
shall not bill an STP port charge nor shall BellSouth pay a port charge; 2) SS7
Network Usage - BellSouth shall bill its tariffed surrogate usage charge and
shall pay usage billed by the Carrier at rates not to exceed those charged by
BellSouth; 3) SS7 Link - BellSouth will bill its tariffed charges for only two
links of each quad ordered. Application of these





                                       10
<PAGE>   11

charges in this manner is designed to reflect the reciprocal use of the
parties' signaling networks. Where interconnection is via A-link connections,
charges for the SS7 interconnection elements are as follows: 1) Port Charge -
BellSouth shall bill its tariffed STP port charge but shall not pay a
termination charge at the Carrier's end office; 2) SS7 Network Usage -
BellSouth shall bill its tariffed surrogate usage charge but shall not pay for
any usage; 3) SS7 Link - BellSouth shall bill its tariffed charges for each
link in the A-link pair but shall not pay the Carrier for any portion of those
links.

          D.     Upon request, the parties shall conduct further negotiations
pursuant to Sections 251 and 252 of the Act regarding the provision of services
described in this Section, and nothing in this Agreement shall prohibit, or
shall be construed to prohibit, such negotiations or any arbitration arising
therefrom, if necessary, provided that neither Powertel nor Carrier
collectively may make more than one such request for negotiations with respect
to the services described in this section in any calendar year during which the
Agreement is in effect.

XV.      NETWORK DESIGN AND MANAGEMENT

         A.      The parties agree to work cooperatively to install and
maintain reliable interconnected telecommunications networks, including but not
limited to, maintenance contact numbers and escalation procedures.  BellSouth
agrees to provide reasonable public notice of changes in the information
necessary for the transmission and routing of services using its local exchange
facilities or networks, as well as of any other changes that would affect the
interoperability of those facilities and networks.

         B.      The interconnection of all networks will be based upon
accepted industry/national guidelines for transmission standards and traffic
blocking criteria, as defined in this Agreement.

         C.      The parties will work cooperatively to apply sound network
management principles by invoking appropriate network management controls, if
technically feasible, e.g.. call gapping, to alleviate or prevent network
congestion.

         D.      Neither party will charge rearrangement, reconfiguration,
disconnection, termination or other such non-recurring fees that may be
associated with the initial reconfiguration of either party's existing network
interconnection arrangements.  Notwithstanding the foregoing, the parties may
charge non-recurring fees for any additions to, or added capacity to, any
existing facility or trunk.

         E.      The parties agree to provide Common Channel Signaling (CCS)
information to one another, where available, in conjunction with all traffic in
order to enable full interoperability of CLASS features and functions except
for features or functions that have not been deployed in the parties'
respective networks, where available.  All CCS signaling parameters will be
provided, including automatic number identification (ANI), originating line
information (OLI), calling party category, charge





                                       11
<PAGE>   12

number, etc.  All privacy indicators will be honored, and the parties agree to
cooperate on the exchange of Transactional Capabilities Application Part (TCAP)
messages to facilitate full interoperability of CCS-based features between the
respective networks.

         F.      For network expansion, the parties agree to review engineering
requirements on a quarterly basis and establish forecasts for trunk utilization
as required by Section VI of this Agreement.  New trunk groups will be
implemented as stated by engineering requirements for both parties.

         G.      The parties agree to provide each other with the proper call
information, i.e. originated call party number and destination call party
number, CIC, and OZZ, including all proper translations for routing between
networks and any information necessary for billing where either party provides
recording capabilities.  The exchange of information is required to enable each
party to bill properly.

         H.      Upon request, the parties shall conduct further negotiations
pursuant to Sections 251 and 252 of the Act regarding the provision of services
described in this Section, and nothing in this Agreement shall prohibit, or
shall be construed to prohibit, such negotiations or any arbitration arising
therefrom, if necessary, provided that neither Powertel nor Carrier
collectively may make more than one such request for negotiations with respect
to the services described in this section in any calendar year during which the
Agreement is in effect.

XVI.     IMPLEMENTATION OF AGREEMENT

          The parties agree to provide the appropriate staff support to ensure
effective implementation, administration of this Agreement and conversion of
pricing for existing services to the appropriate rates contained in this
Agreement.


XVII.    AUDITING PROCEDURES

         A.       Within thirty (30) days of a party's receipt of a written
request to audit, such party must provide  a mutually acceptable independent
auditor (the "Auditor") with access to such party's books and records so that
the Auditor can perform an audit of the billing of traffic between the parties.
The parties agree to retain records of call detail for a minimum of nine months
from which the PLU can be ascertained.  The audit shall be performed by the
Auditor during normal business hours at an office designated by the party being
audited.  Audit requests shall not be submitted more frequently than once per
calendar year. The PLU shall be adjusted based upon the audit results and shall
apply to the usage for the quarter the audit was completed, the usage for the
quarter prior to the completion of the audit, and to the usage following the
completion of the audit until again revised pursuant to a subsequent audit. The
party requesting the audit shall pay the cost of the audit, including the
Auditor's fees, except that if, as a result of the audit, the party being
audited is found to have overstated the PLU by twenty percentage points or
more, that party shall reimburse the party requesting the audit for the cost of
the audit, including the Auditor's fees.





                                       12
<PAGE>   13

         B.      For combined interstate and intrastate Carrier Toll Traffic
terminated by BellSouth over the same facilities, Carrier shall provide a PIU
factor to BellSouth.  Carrier does not intend to provide interexchange carrier
services to BellSouth end-users. Nevertheless, should Carrier in the future
provide toll services through the use of network switched access services, then
all jurisdictional report requirements, rules and regulations specified in
E2.3.14 of BellSouth's Intrastate Access Services Tariff will apply to
Carrier's services and operations to the same degree and in the same manner as
such requirements, rules, and regulations apply to BellSouth. After the Local
Traffic percentage has been determined by use of the PLU factor for application
and billing of local interconnection, the PIU factor will be used for
application and billing of interstate and intrastate access charges, as
appropriate.

XVIII.       LIABILITY AND INDEMNIFICATION

         A.      Liability Cap.

         (1) With respect to any claim or suit, whether based in contract, tort

the extent the damage is caused by such Party's gross negligence or willful
misconduct.

         D.      Each party shall, to the greatest extent permitted by the law
governing this Agreement ("Applicable Law"), include in its tariff (if it files
one) or, where it does not file a tariff, in an appropriate contract with its
customers that relates to the subject matter of this Agreement, a limitation of
liability (i) that covers the other party to the same extent the first party
covers itself and (ii) that limits the amount of damages a customer may recover
to the amount charged the applicable customer for the service that gave rise to
such loss.

         E.      No Consequential Damages - EXCEPT AS OTHERWISE PROVIDED IN
THIS SECTION XVIII, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY
INDIRECT, INCIDENTAL, CONSEQUENTIAL, RELIANCE, OR SPECIAL DAMAGES SUFFERED BY
SUCH OTHER PARTY (INCLUDING WITHOUT LIMITATION DAMAGES FOR HARM TO BUSINESS,
LOST REVENUES, LOST SAVINGS, OR LOST PROFITS SUFFERED BY SUCH OTHER PARTY),
REGARDLESS OF THE FORM OF ACTION, WHETHER IN CONTRACT, WARRANTY, STRICT
LIABILITY, OR TORT, INCLUDING WITHOUT LIMITATION NEGLIGENCE OF ANY KIND WHETHER
ACTIVE OR PASSIVE, AND REGARDLESS OF WHETHER THE PARTIES KNEW OF THE
POSSIBILITY THAT SUCH DAMAGES COULD RESULT.  EACH PARTY HEREBY AGREES TO HOLD
HARMLESS THE OTHER PARTY AND SUCH OTHER PARTY'S AFFILIATES, AND THEIR
RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS FROM ALL SUCH DAMAGES.
PROVIDED, HOWEVER, NOTHING CONTAINED IN THIS SECTION XVIII SHALL LIMIT A

NEGLIGENCE, OR FAILURE TO HONOR ONE OR MORE OF THE MATERIAL PROVISIONS OF THIS
AGREEMENT IN ONE OR MORE MATERIAL RESPECTS; (II) BODILY INJURY, DEATH OR DAMAGE

INDEMNIFICATION OBLIGATIONS AS SPECIFIED HEREIN.

         F.      Obligation to Indemnify - Each party shall, and hereby agrees
to, defend at the other party's request, indemnify and hold harmless the other
party and each of its officers, directors, employees and agents (each, an
"Indemnitee") against and in respect





                                       14
<PAGE>   15

of any loss, debt, liability, damage, obligation, claim, demand, judgment or
settlement of any nature or kind, known or unknown, liquidated or unliquidated,
including without limitation all reasonable costs and expenses incurred (legal,
accounting or otherwise) (collectively, "Damages") arising out of, resulting
from or based upon any pending or threatened claim, action, proceeding or suit
by any third party (a "Claim") (i) arising from any breach of any
representation, warranty or covenant made by such indemnifying party (the
"Indemnifying Party") in this Agreement, (ii) based upon injuries or damage to
any person or property or the environment arising out of or in connection with
this Agreement that are the result of the Indemnifying Party's actions, breach
of Applicable Law, or status of its employees, agents and subcontractors, or
(iii) for actual or alleged infringement of any patent, copyright, trademark,
service mark, trade name, trade dress, trade secret or any other intellectual
property right, now known or later developed (referred to as "Intellectual
Property Rights") to the extent that such Claim for infringement arises from
lndemnitee's use of the services provided to it under this Agreement.

         G.      Each party's failure to perform under this Agreement shall be
excused by labor strikes, civil commotion, criminal actions taken against them,
acts of God, and other circumstances beyond their reasonable control.

         H.      The obligations of the parties contained within this section
shall survive/e the expiration of this Agreement..

XIX.     MORE FAVORABLE PROVISIONS

         A.      The parties agree that if ---

                 1.       the FCC or the Commission finds that the terms of
this Agreement are inconsistent in one or more material respects with any of
its or their respective decisions, rules, or regulations, or

                 2.       the FCC or the Commission preempts the effect of this
Agreement, then, in either case, upon such occurrence becoming final and no
longer subject to administrative or judicial review, the parties shall
immediately commence good faith negotiations to conform this Agreement to the
requirements of any such decision, rule, regulation, or preemption.  The
revised agreement shall have the same effective date as the initial FCC or
Commission action giving rise to such negotiations.  The rates, terms, and
conditions of any new agreement shall not be applied retroactively to any
period prior to such effective date except to the extent that such retroactive
effect is expressly required by such FCC or Commission decision, rule,
regulation, or preemption.

         B.      In the event that BellSouth, either before or after the
Effective Date, enters into an agreement with any other telecommunications
carrier (an "Other





                                       15
<PAGE>   16

Interconnection Agreement") which provides for the provision within a state of
any of the arrangements covered by this Agreement upon rates, terms or
conditions that differ from the rates, terms and conditions for such
arrangements set forth in this Agreement ("Other Terms"), then BellSouth shall
be deemed thereby to have offered such arrangements to Carrier upon such Other
Terms in that state only, which Carrier may accept as provided in Part E of
this Section. In the event that Carrier accepts such offer within sixty (60)
days after the Commission, or the FCC, as the case may be, approves such Other
Interconnection Agreement pursuant to Section 252 of the Act, or within thirty
(30) days after Carrier acquires actual knowledge of an Other Interconnection
Agreement not requiring the approval of the Commission pursuant to Section 252
of the Act, as the case may be, such Other Terms shall be effective between
BellSouth and Carrier as of the effective date of such Other Interconnection
Agreement or the Effective Date of this Agreement, whichever is later.  In the
event that Carrier accepts such offer more than sixty (60) days after the
Commission, or the FCC, as the case may be, approves such Other
Interconnection Agreement pursuant to Section 252 of the Act, or more than
thirty (30) days after acquiring actual knowledge of an Other Interconnection
Agreement not requiring the approval of the Commission pursuant to Section 252
of the Act, as the case may be, such Other Terms shall be effective between
BellSouth and Carrier as of the date on which Carrier accepts such offer.

         C.      In the event that after the Effective Date the FCC or the
Commission having jurisdiction enters an order (an "Interconnection Order")
requiring BellSouth to provide within a particular state any of the
arrangements covered by this Agreement upon Other Terms, then upon such
Interconnection Order becoming final and not subject to further administrative
or judicial review, BellSouth shall be deemed to have offered such arrangements
to Carrier upon such Other Terms, which Carrier may accept as provided in Part
E of this Section. In the event that Carrier accepts such offer within sixty
(60) days after the date on which such Interconnection Order becomes final and
not subject to further administrative or judicial review, such Other Terms
shall be effective between BellSouth and Carrier as of the effective date of
such Interconnection Order or the Effective Date of this Agreement, whichever
is later.  In the event that Carrier accepts such offer more than sixty (60)
days after the date on which such Interconnection Order becomes final and not
subject to further administrative or judicial review, such Other Terms shall be
effective between BellSouth and Carrier as of the date on which Carrier accepts
such offer.

         D.      In the event that after the Effective Date BellSouth files and
subsequently receives approval for one or more intrastate or interstate tariffs
(each, an "Interconnection Tariff") offering to provide within a particular
state any of the arrangements covered by this Agreement upon Other Terms, then
upon such Interconnection Tariff becoming effective, BellSouth shall be deemed
thereby to have offered such arrangements to Carrier upon such Other Terms in
that state only, which Carrier may accept as provided in Part E of this
Section. In the event that Carrier accepts such offer within sixty (60) days
after the date on which such Interconnection Tariff becomes effective, such
Other Terms shall be effective between BellSouth and





                                       16
<PAGE>   17

Carrier as of the effective date of such Interconnection Tariff or the
Effective Date of this Agreement, whichever is later.  In the event that
Carrier accepts such offer more than sixty (60) days after the date on which
such Interconnection Tariff becomes effective, such Other Terms shall be
effective between BellSouth and Carrier as of the date on which Carrier accepts
such offer.

         E.      In the event that BellSouth is deemed to have offered Carrier
the arrangements covered by this Agreement upon Other Terms, Carrier in its
sole discretion may accept such offer either --

                 1.       by accepting such Other Terms in their entirety; or

                 2.       by accepting the Other Terms that directly relate to
any one or more of the following arrangements as described by lettered
category:

                          a.  local interconnection (including transport and
termination),              
                           
                          b.  interLATA and IntraLATA toll traffic
interconnection,           
                           
                          c.  unbundled access to network elements, which
include: local loops, network interface devices, switching capability,
interoffice transmission facilities, signaling networks and call-related
databases, operations support systems functions, operator services and
directory assistance, and any elements that result from subsequent bona fide
requests,

                          d.  access to poles, ducts, conduits and 
rights-of-way,             
                           
                          e.  access to 911/E911 emergency network,
                           
                          f.  collocation, or
                           
                          g.  access to telephone numbers.

The terms of this Agreement, other than those affected by the Other Terms
accepted by Carrier, shall remain in full force and effect.

         F.      Corrective Payment.       In the event that --

                 1.       BellSouth and Carrier revise this Agreement pursuant
to Part A of this Section, or

                 2.       Carrier accepts a deemed offer of Other Terms
pursuant to Part E of this Section,

then BellSouth or Carrier, as applicable, shall make a corrective payment to
the other party to correct for the difference between (a) the rates set forth
herein and (b) the rates in such revised agreement or Other Terms for the
period from (x) the effective date of





                                       17
<PAGE>   18

such revised agreement or Other Terms until (y) the later of the date that the
parties execute such revised agreement or the parties implement such Other
Terms, plus simple interest at a rate equal to the thirty (30) day commercial
paper rate in effect from time to time for high-grade, unsecured notes sold
through dealers by major corporations in multiples of $1,000.00 as regularly
published in The Wall Street Journal.

XX.      TAXES

         A.      For the purposes of this section, the terms "taxes" and "fees"
shall include but not be limited to federal, state or local sales, use, excise,
gross receipts or other taxes or tax-like fees of whatever nature and however
designated (including tariff surcharges and any fees, charges or other
payments, contractual or otherwise, for the use of public streets or rights of
way, whether designated as franchise fees or otherwise) imposed, or sought to
be imposed, on or with respect to the services furnished hereunder or measured
by the charges or payments therefor, excluding any taxes levied on income.

         B.      Taxes and fees imposed on the providing party, which are
neither permitted nor required to be passed on by the providing party to its
customer, shall be borne and paid by the providing party.  Taxes and fees
imposed on the purchasing party, which are not required to be collected and/or
remitted by the providing party, shall be borne and paid by the purchasing
party.

         C.      Taxes and fees imposed on the purchasing party shall be borne
by the purchasing party, even if the obligation to collect and/or remit such
taxes or fees is placed on the providing party.  To the extent permitted by
applicable law, any such taxes and/or fees shall be shown as separate items on
applicable billing documents between the parties.  Notwithstanding the
foregoing, the purchasing party shall remain liable for any such taxes and fees
regardless of whether they are actually billed by the providing party at the
time that the respective service is billed.

         D.      If the purchasing party determines that in its opinion any
such taxes or fees are not lawfully due, the providing party shall not bill
such taxes or fees to the purchasing party if the purchasing party provides
written certification, reasonably satisfactory to the providing party, stating
that it is exempt or otherwise not subject to the tax or fee, setting forth the
basis therefor, and satisfying any other requirements under applicable law.  If
any authority seeks to collect any such tax or fee that the purchasing party
has determined and certified not to be lawfully due, or any such tax or fee
that was not billed by the providing party, the purchasing party may contest
the same in good faith, at its own expense.  In the event that such contest
must be pursued in the name of the providing party, the providing party shall
permit the purchasing party to pursue the contest in the name of providing
party and providing party shall have the opportunity to participate fully in
the preparation of such contest.  In any such contest, each party shall
promptly furnish the others with copies of all filings in any proceeding,





                                       18
<PAGE>   19

protest, or legal challenge, all rulings issued in connection therewith, and
all correspondence between the purchasing party and the taxing authority.

         E.      If it is ultimately determined that any additional amount of
such a tax or fee is due to the imposing authority, the purchasing party shall
pay such additional amount, including any interest and penalties thereon.
Notwithstanding any provision to the contrary, the purchasing party shall
protect, indemnify and hold harmless (and defend at the purchasing party's
expense) the providing party from and against any such tax or fee, interest or
penalties thereon, or other charges or payable expenses (including reasonable
attorney fees) with respect thereto, which are reasonably and necessarily
incurred by the providing party in connection with any claim for or contest of
any such tax or fee.  Each party shall notify the other party in writing of any
assessment, proposed assessment or other claim for any additional amount of
such a tax or fee by a taxing authority; such notice to be provided, if
possible, at least ten (10) days prior to the date by which a response, protest
or other appeal must be filed, but in no event later than thirty (30) days
after receipt of such assessment, proposed assessment or claim.

         F.      Taxes and fees imposed on the providing party, which are
permitted or required to be passed on by the providing party to its customer,
shall be borne by the purchasing party.  To the extent permitted by applicable
law, any such taxes and/or fees shall be shown as separate items on applicable
billing documents between the parties.  Notwithstanding the foregoing, the
purchasing party shall remain liable for any such taxes and fees regardless of
whether they are actually billed by the providing party at the time that the
respective service is billed.

         G.      If the purchasing party disagrees with the providing party's
determination as to the application or basis for any such tax or fee, the
parties shall consult with respect to the imposition and billing of such tax or
fee and with respect to whether to contest the imposition of such tax or fee.
Notwithstanding the foregoing, the providing party shall retain responsibility
for determining whether and to what extent any such taxes or fees are
applicable.  The providing party shall further retain responsibility for
determining whether and how to contest the imposition of such taxes or fees,
provided, however, the parties agree to consult in good faith as to such
contest and that any such contest undertaken at the request of the purchasing
party shall be at the purchasing party's expense. In the event that such
contest must be pursued in the name of the providing party, the providing party
shall permit the purchasing party to pursue the contest in the name of the
providing party and the providing party shall have the opportunity to
participate fully in the preparation of such contest.

         H.      If after consultation in accordance with the preceding
Section, the purchasing party does not agree with the providing party's final
determination as to the application or basis of a particular tax or fee, and if
the providing party, after receipt of a written request by the purchasing party
to contest the imposition of such tax or fee with the imposing authority, fails
or refuses to pursue such contest or to allow such contest





                                       19
<PAGE>   20

by the purchasing party, the purchasing party may utilize the dispute
resolution process outlined in Section XXII of this Agreement.  Utilization of
the dispute resolution process shall not relieve the purchasing party from
liability for any tax or fee billed by the providing party pursuant to this
subsection during the pendency of such dispute resolution proceeding.  In the
event that the purchasing party prevails in such dispute resolution proceeding,
it shall be entitled to a refund in accordance with the final decision therein.
Notwithstanding the foregoing, if at any time prior to a final decision in such
dispute resolution proceeding the providing party initiates a contest with the
imposing authority with respect to any of the issues involved in such dispute
resolution proceeding, the dispute resolution proceeding shall be dismissed as
to such common issues and the final decision rendered in the contest with the
imposing authority shall control as to such issues.

         I.      In the event that all or any portion of an amount sought to be
collected must be paid in order to contest the imposition of any such tax or
fee, or to avoid the existence of a lien on the assets of the providing party
during the pendency of such contest, the purchasing party shall be responsible
for such payment and shall be entitled to the benefit of any refund or
recovery.  If it is ultimately determined that any additional amount of such a
tax or fee is due to the imposing authority, the purchasing party shall pay
such additional amount, including any interest and penalties thereon.

         J.      Notwithstanding any provision to the contrary, the purchasing
party shall protect, indemnify and hold harmless (and defend at the purchasing
party's expense) the providing party from and against any such tax or fee,
interest or penalties thereon, or other reasonable charges or payable expenses
(including reasonable attorney fees) with respect thereto, which are incurred
by the providing party in connection with any claim for or contest of any such
tax or fee.  Each party shall notify the other party in writing of any
assessment, proposed assessment or other claim for any additional amount of
such a tax or fee by a taxing authority; such notice to be provided, if
possible, at least ten (10) days prior to the date by which a response, protest
or other appeal must be filed, but in no event later than thirty (30) days
after receipt of such assessment, proposed assessment or claim.

         K.      In any contest of a tax or fee by one party, the other party
shall cooperate fully by providing records, testimony and such additional
information or assistance as may reasonably be necessary to pursue the contest.
Further, the other party shall be reimbursed for any reasonable and necessary
out-of-pocket copying and travel expenses incurred in assisting in such
contest. Notwithstanding any other provision in this Agreement, each party
agrees to indemnify and hold harmless the other party from and against any
losses, damages, claims, demands, suits, liabilities, and expenses including
reasonable attorney's fees, that arise out of its failure to perform its
obligations under this Section.

XXI.    TREATMENT OF PROPRIETARY AND CONFIDENTIAL INFORMATION

         A.      The parties agree that it may be necessary to provide each
other with certain confidential information, including trade secret
information, including but not limited to, technical and business plans,
technical information, proposals, specifications, drawings, procedures,
customer account data, call detail records and like information (hereinafter
collectively referred to as "Information"). The parties agree that if
Information is provided in written, graphic or other usable form and clearly
marked with a confidential, private or proprietary legend, then that
Information will be returned to the owner within a reasonable time.  Both
parties agree that such marked Information shall not be copied or reproduced in
any form except to the extent required to perform this Agreement. The parties
shall protect any Information received from distribution, disclosure or
dissemination to anyone except employees of the parties with an identifiable
need to know such Information who agree in writing to be bound by the terms of
this Section; however, in no event shall any of Carrier's Information be
disclosed to any person employed by an affiliate of BellSouth engaged in the
provision of CMRS. In the event any person having had access to Carrier's
Information is subsequently employed by an affiliate of BellSouth engaged in
the provision of CMRS, such person shall be required to agree in writing not to
reveal or use such Information. The parties will use the same standard of care
to protect Information received as they would use to protect their own
