          prohibited or unenforceable in any jurisdiction shall, as to such

          unenforceability without invalidating the remaining provisions hereof
          or affecting the validity or remaining provisions hereof or affecting
          the validity or enforceability of such provision in any other
          jurisdiction.

     3.   Agreement to Remain in Full Force and Effect. This Amendment shall be

     6.   Counterparts. This Amendment may be executed in counterparts, each of
          ------------
          which shall be deemed an original, but all of which together shall
          constitute one and the same instrument.

     7.   Governing Law. This Amendment shall be construed in accordance with
          -------------
          the laws of the State of Washington without reference to the choice of

                  Each Seller (as to itself) and the Company represent and
warrant to each other that:

                  4.1    Organization and Standing. It is a corporation or
                         -------------------------
limited liability company, as the case may be, duly organized, validly existing
and in good standing under the laws of its jurisdiction of organization and has
the requisite power and authority to own, lease and operate its properties and
to carry on its business as now being conducted. It is duly qualified to do
business in each jurisdiction where the character of its properties owned or
held under lease or the nature of its activities makes such qualification
necessary other than any such jurisdiction in which the failure to be so
qualified would not have a Material Adverse Effect on it or materially adversely
affect the transactions contemplated hereby or its ability to perform its
obligations under this Agreement.

                  4.2    Power and Authority. It has the requisite power and
                         -------------------
authority to execute, deliver and perform this Agreement and each other
instrument, document, certificate and agreement required or contemplated to be
executed, delivered and performed by it hereunder and thereunder to which it is
or will be a party.

                  4.3    Due Authorization. The execution and delivery of this
                         -----------------
Agreement by it and the consummation of the transactions contemplated hereby
have been duly and validly authorized by its Board of Directors (or equivalent
body) and no other proceedings on its part which have not been taken (including,
without limitation, approval of its stockholders, partners or members) are
necessary to authorize this Agreement or to consummate the transactions
contemplated hereby.

                  4.4    Enforceability. This Agreement has been duly executed
                         --------------
and delivered by it and constitutes its valid and binding obligation enforceable
against it in accordance with its terms, except as such enforceability may be
limited by bankruptcy, insolvency, moratorium or other similar laws affecting or
relating to enforcement of creditors' rights generally and may be subject to
general principles of equity.

                  4.5    No Breach. After giving effect to the transactions
                         ---------
contemplated hereby, it is not in breach of any obligation under this Agreement.

                  4.6    Consents; No Conflicts. Neither the execution, delivery
                         ----------------------
and performance by it of this Agreement nor the consummation of the transactions
contemplated hereby will (a) conflict with, or result in a breach or violation
of, any provision of its organizational documents; (b) subject to obtaining the
Consents set forth on Schedule 4.6, constitute, with or without the giving of
notice or passage of time or both, a breach, violation or default, create a
Lien, or give rise to any right of termination, modification, cancellation,
prepayment or acceleration, under (i) any Law or License or (ii) any note, bond,
mortgage, indenture, lease, agreement or other instrument, in each case which is
applicable to or binding upon it or any of its assets; or (c) require any
Consent (other than those set forth on Schedule 4.6 or the approval of its board
of

                                      -6-

directors, general partner, stockholders or similar constituent bodies, as the
case may be (which approvals have been obtained)), except in each case, where
such breach, violation, default, Lien, right, or the failure to obtain or give
such Consent would not have a Material Adverse Effect on it or materially
adversely affect the transactions contemplated hereby. To its knowledge, except
as set forth on Schedule 4.6, there is no fact relating to it or its Affiliates
that would be reasonably expected to prevent it from consummating the
transactions contemplated hereby or disqualify the Company from obtaining the
Consents (including without limitation, FCC Consent) required in order to
consummate the Tritel License Transfer.

                  4.7    Litigation. Except as set forth on Schedule 4.7, there
                         ----------
is no action (including court action), proceeding or investigation pending or,
to its knowledge, threatened against it or any of its properties or assets that
would be reasonably expected to have an adverse effect on its ability to
consummate the transactions contemplated hereby or to fulfill its obligations
under this Agreement, which seeks to prevent or challenge the transactions
contemplated hereby, or which seeks to have an adverse effect on the Company.

the rules on holding designated entity licenses, the FCC rules on foreign
ownership and the CMRS spectrum cap.

                  4.9    Brokers. It has not employed any broker, finder or
                         -------
investment banker or incurred any liability for any brokerage fees, commissions
or finder's fees in connection with the transactions contemplated hereby.

                  4.10   Each of Tritel-Florida, with respect (where applicable)
to the Florida Licenses, and Tritel-Georgia, with respect (where applicable) to
the Georgia Licenses, represents and warrants to the Company that:

                  (a)    Tritel Licenses. It is the authorized legal holder,
                         ---------------
free and clear of any Liens (other than Liens securing the FCC Debt), of such
Licenses, true and correct copies of which are attached to Schedules I and II
hereto, as applicable. Such Licenses are, and on the Closing Date will be, valid
and in full force and effect. Except as set forth on Schedule 4.10 and for
proceedings affecting the PCS or wireless communications services industry
generally, including investigations by governmental agencies of bidding
practices of bidders in the FCC auctions of PCS spectrum, there is not pending,
nor to its knowledge, threatened against it or such Licenses, any application,
action (including court action), petition, objection or other pleading, or any
proceeding with the FCC which questions or contests the validity of, or seeks
the revocation, non-renewal or suspension of, any of such Licenses, which seeks
the imposition of any modification or amendment with respect thereto, or which
adversely affects the ability of the Company to employ such Licenses in the
Company's business after the Closing Date or seeks the payment of a fine,
sanction, penalty, damages or contribution in connection with the use of any of
such Licenses. Such Licenses are not subject to any conditions other than those
appearing on the face of the Licenses themselves and those imposed by FCC Law.

                  (b)    Tritel Debt; Solvency. Each item of FCC Debt being
                         ---------------------
assumed by the Company shall be such Seller's bona fide obligation. Such Seller
is Solvent after giving effect to the consummation of the transactions
contemplated hereby.

                  (c)    Transferability. Neither the execution, delivery and
                         ---------------
performance by such Seller of this Agreement nor the assumption by the Company
of the FCC Debt will (a) constitute, with or without the giving of notice or
passage of time or both, a breach, violation or default, create a Lien, or give
rise to any right of termination, modification, cancellation, prepayment or
acceleration, under any note, bond, mortgage, indenture, lease, agreement or
other instrument, in each case which is applicable to or binding upon such
Seller or any of the FCC Debt; or (b) require any Consent (other than those set
forth on Schedule 4.6) or the approval of such Seller's board of directors
(which approval has been obtained).

it receives in connection with the negotiation or performance of this Agreement,
and shall not disclose such Confidential Information, and shall cause its
Representatives not to disclose such Confidential Information, to anyone except
the receiving party's Affiliates and Representatives and any other Person that

All Confidential Information furnished pursuant to this Agreement shall be

threatened to be disclosed, shall have the right and remedy to have this Section
5.2 specifically enforced by any court having jurisdiction, it being
acknowledged and agreed that money damages will not provide an adequate remedy
to such party. Nothing in this Section 5.2 shall be construed to limit the right
of any party to collect money damages in the event of breach of this Section
5.2.

          (d)  Anything else in this Agreement notwithstanding, each party shall
have the right to disclose any information, including Confidential Information
of the other party or such other party's Affiliates, in any filing with any
regulatory agency, court or other authority or any disclosure to a trustee of
public debt of a party to the extent that the disclosing party determines in
good faith that it is required by Law, regulation or the terms of such debt to
do so, provided that any such disclosure shall be as limited in scope as
possible and shall be made only after giving the other party as much notice as
practicable of such required disclosure and an opportunity to contest such
disclosure if possible.

material obligation or liability, absolute or contingent, relating to or
affecting the Florida Licenses or Georgia Licenses, as applicable, or their use;

either Seller or any of its Affiliates in the performance of their respective
obligations under this Agreement, except to the extent (but only to the extent)
any such Losses arise out of or result from the gross negligence or willful
misconduct of such Section 7.2 Indemnified Party or its Affiliates. Further,

               -----------------------------
him or it in connection with the investigation, defense, or disposition of any
action, suit or other proceeding in which any Section 7.3 Indemnified Party may
be involved or with which he or it may be threatened that arises out of or
results from (a) any representation or warranty of the Company contained in this
Agreement being untrue in any material respect as of the date on which it was
made or (b) any material default by the Company or any of its Affiliates in the

           7.4  Procedures.
                ----------

          (a)   The terms of this Section 7.4 shall apply to any claim (a
"Claim") for indemnification under the terms of Sections 7.2 or 7.3. The Section
 -----
7.2 Indemnified Party or Section 7.3 Indemnified Party (each, an "Indemnified
                                                                  -----------
Party"), as the case may be, shall give prompt written notice of such Claim to
-----
the indemnifying party (the "Indemnifying Party") under the applicable Section,
                             ------------------
which party may assume the defense thereof, provided that any delay or failure
to so notify the Indemnifying Party shall relieve the Indemnifying Party of its
obligations hereunder only to the extent, if at all, that it is materially
prejudiced by reason of such delay or failure. The Indemnified Party shall have
the right to approve any counsel selected by the Indemnifying Party and to
approve the terms of any proposed settlement, such approval not to be
unreasonably delayed or withheld (unless such settlement provides only, as to
the Indemnified Party, the payment of money damages actually paid by the
Indemnifying Party and a complete release of the Indemnified Party in respect of
the claim in question). Notwithstanding any of the foregoing to the contrary,
the provisions of this Article VII shall not be construed so as to provide for
the indemnification of any Indemnified Party for any liability to the extent
(but only to the extent) that such indemnification would be in violation of
applicable law or that such liability may not be waived, modified or limited
under applicable law, but shall be construed so as to effectuate the provisions
of this Article VII to the fullest extent permitted by law.

          (b)  In the event that the Indemnifying Party undertakes the defense
of any Claim, the Indemnifying Party will keep the Indemnified Party advised as
to all material developments in connection with such Claim, including, but not
limited to, promptly furnishing the Indemnified Party with copies of all
material documents filed or served in connection therewith.

          (c)  In the event that the Indemnifying Party fails to assume the
defense of any Claim within ten business days after receiving written notice
thereof, the Indemnified Party shall have the right, subject to the Indemnifying
Party's right to assume the defense pursuant to the provisions of this Article
VII, to undertake the defense, compromise or settlement of such Claim for the
account of the Indemnifying Party. Unless and until the Indemnified Party
assumes the defense of any Claim, the Indemnifying Party shall advance to the
Indemnified Party any of its reasonable attorneys' fees and other costs and
expenses incurred in connection with the defense of any such action or
proceeding. Each Indemnified Party shall agree in writing prior to any such
advancement that, in the event he or it receives any such advance, such
Indemnified Party shall reimburse the Indemnifying Party for such fees, costs
and expenses to the extent that it shall be determined that he or it was not
entitled to indemnification under this Article VII.

          (d)  In no event shall an Indemnifying Party be required to pay in
connection with any Claim for more than one firm of counsel (and local counsel)
for each of the following groups of Indemnified Parties: (i) Sellers, their
Affiliates, and the shareholders, members, managers, officers, employees, agents
and/or the legal representatives of any of them; and (ii) the

                                      -15-

Company and its Affiliates, and the shareholders, members, managers, officers,
employees, agents and/or the legal representatives of any of them.

          (b)   by any party by written notice to the other parties, if the
Closing shall not have occurred on or before the date that is two years after
the date hereof, provided that the party electing to exercise such right is not
otherwise in breach of its obligations under this Agreement; or

          (c)   by any party by written notice to the other parties, if the
consummation of the transactions contemplated hereby shall be prohibited by a
final, non-appealable order, decree or injunction of a court of competent
jurisdiction.

           8.2  Effect of Termination. (a) In the event of a termination of this
                ---------------------
Agreement, no party hereto shall have any liability or further obligation to any
other party to this Agreement, except as set forth in paragraph (b) below, and
except that nothing herein will relieve any party from liability for any breach
by such party of this Agreement.

          (a)   In the event of a termination of this Agreement pursuant to
Section 8.1, all provisions of this Agreement shall terminate, except Section
5.2 and Articles VII and IX.

may be waived by the party

<PAGE>

or parties entitled to the benefits thereof only by a written instrument signed
by the party granting such waiver, but such waiver or failure to insist upon
strict compliance with such obligation, covenant, agreement or condition shall
not operate as a waiver of, or estoppel with respect to, any subsequent or other
failure. Whenever this Agreement requires or permits consent by or on behalf of
any party hereto, such consent shall be given in writing in a manner consistent
with the requirement for a waiver of compliance as set forth in this Section
9.2.

           9.3  Notices. All notices or other communications hereunder shall be

construed in accordance with the laws of the State of New York without giving

irrevocably and unconditionally consent to submit to the non-exclusive

America located in the County of New York, New York (the "New York Courts") for
                                                          ---------------
any litigation arising out of or relating to this Agreement and the transactions

                ------------
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument.

           9.7  Interpretation. The article and section headings contained in
                --------------
this Agreement are for convenience of reference only, are not part of the
agreement of the parties and shall not affect in any way the meaning or
interpretation of this Agreement. All pronouns and any variations thereof shall
