Item 14. Indemnification of Directors and Officers

   The Delaware General Corporation Law authorizes corporations to limit or
eliminate the personal liability of directors to corporations and their
stockholders for monetary damages for breach of directors' fiduciary duty of
care. The duty of care requires that, when acting on behalf of the
corporation, directors must exercise an informed business judgment based on
all material information reasonably available to them. In the absence of the
limitations authorized by the Delaware statute, directors could be accountable
to corporations and their stockholders for monetary damages for conduct that
does not satisfy their duty of care. Although the statute does not change
directors' duty of care, it enables corporations to limit available relief to
equitable remedies such as injunction or rescission. The second restated
certificate of incorporation limits the liability of Triton's directors to
Triton or its stockholders to the fullest extent permitted by the Delaware
statute. Specifically, the directors of Triton will not be personably liable
for monetary damages for breach of a director' s fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to
Triton or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the Delaware General Corporation Law (which relates
to the unlawful payment of dividend or unlawful stock purchase or redemption
by a corporation) or (iv) for any transaction from which a director derived an
improper personal benefit. The inclusion of this provision in the second
restated certificate of incorporation may have the effect of reducing the
likelihood of derivative litigation against directors and may discourage or
deter stockholders or management from bringing a lawsuit against directors for
breach of their duty of care, even though such an action, if successful, might
otherwise have benefited Triton and its stockholders. Under the applicable
provisions of the Delaware General Corporation Law, in general, a corporation
may indemnify its directors, officers, employees or agents against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by them in connection with any action, suit
or proceeding brought by third parties to which they may be made parties by
reason of their being or having been directors, officers, employees or agents
and shall so indemnify such persons only if they acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests
of the corporation and, with respect to any criminal action or proceeding, had
no reasonable cause to believe their conduct was unlawful. The second restated
certificate of incorporation gives Triton the power to indemnify its officers,
directors, employees and agents to the full extent permitted by Delaware law.

                                     II-1
<PAGE>

   Immediately prior to the consummation of the offering, Triton plans to
enter into indemnification agreements with each of its directors and certain
of its executive officers which generally provide for indemnification of the
director or officer to the fullest extent provided by law. In addition, Triton
has purchased directors' and officers' liability insurance coverage for its
directors and certain of its officers in amounts customary for similarly
situated companies.

Item 17. Undertakings

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

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provision, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act of 1933 and is, therefore, unenforceable. In the event that a claim of
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted against the Registrant by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Securities Act of 1933 and will be governed
by the final adjudication of such issue.

   The undersigned Registrant hereby undertakes that:

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

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

underwritten offering and constitutes a bona fide distribution of such Common

which results in the Transfer by such Stockholder (together with any other
Stockholder participating in such single transaction or series of related

          4.2  Right of First Offer.
               --------------------

          (a) If a Stockholder (each a "Seller") desires to Transfer any or all
                                        ------
of its shares of Company Stock (collectively, the "Offered Shares"), such Seller
shall give written notice (the "Offer Notice") to the Company and to each
                                ------------
Stockholder entitled to become the First

                                       20
<PAGE>

Offeree of such Offered Shares, as determined below.  Each Offer Notice shall
describe in reasonable detail the number of shares of each class of Offered
Shares, the cash purchase price requested and all other material terms and
conditions of the proposed Transfer. The Offer Notice shall constitute an
irrevocable offer (a "First Offer") to sell all (and not less than all) of the
                      -----------
Offered Shares to the First Offeree(s) at a cash price equal to the price
contained in such Offer Notice and upon the same terms as the terms contained in
such Offer Notice.  The First Offeree(s) shall have the irrevocable right and
option, exercisable as provided below, but not the obligation, to accept the
First Offer as to all (and not less than all) of the Offered Shares.  The "First
                                                                           -----
Offeree(s)" shall be determined as follows:
- ----------
                    (i) If the Seller is a Cash Equity Investor, AT&T PCS shall
be First Offeree;

                    (ii) If the Seller is AT&T PCS, each Cash Equity Investor
shall be the First Offeree; and

                    (iii) If the Seller is any Stockholder other than a Cash
Equity Investor, AT&T PCS shall be the First Offeree.

          (b) The option provided for herein shall be exercisable by the First
Offeree(s) by giving written notice (a "Purchase Notice"), that the First
                                        ---------------
Offeree desires to purchase all (and not less than all) of such Offered Shares
from the Seller, the Stockholders (other than the Seller) and the Company not
later than ten (10) business days (the "First Offer Period") after the date of
                                        ------------------
the Offer Notice.  If the Cash Equity Investors are First Offeree and two or
more Cash Equity Investors notify the Seller of their desire to purchase all of
the Offered Shares, then each Cash Equity Investor shall acquire the proportion
of such Offered Shares as the number of shares of Company Stock owned by such
Cash Equity Investor bears to the total number of shares of Company Stock owned
by all Cash Equity Investors who elected to purchase all of the Offered Shares.
If Offered Shares are purchased by more than one purchaser, the purchase price
shall be allocated among the parties purchasing the shares on the basis of the
number of shares being so purchased.  The purchase of the Offered Shares by the
First Offeree(s) shall be closed at the principal executive offices of the
Company on a date specified by the First Offeree(s) upon at least five (5)
business days' notice, that is within thirty (30) days after the expiration of
the First Offer Period; provided, however, that if such purchase is subject to
the consent of the FCC or any public service or public utilities commission, the
purchase of the Offered Shares shall be closed on the first business day after
all such consents shall have been obtained by Final Order.

          (c) If the First Offeree(s) decline (which shall include the failure
to give timely notice of acceptance) to purchase all of the Offered Shares
subject to the First Offer within the First Offer Period, the Seller shall have
the right (for a period of ninety (90) days following the expiration of the
First Offer Period) to consummate the sale of the Offered Shares to any Person;
provided, however, that the purchase price of such Offered Shares payable by

                                       21
<PAGE>

such Person must be at least equal to the cash purchase price thereof set forth
in the Offer Notice and all other terms and conditions of any such sale shall
not be more beneficial to such third party than those contained in the Offer
Notice.  If any Offered Shares are not sold pursuant to the provisions of this
Section 4.2 prior to the expiration of the ninety (90) day period specified in
- -----------
the immediately preceding sentence, such Offered Shares shall become subject
once again to the provisions and restrictions hereof.

          (d) The purchase price of any Offered Shares Transferred pursuant to
this Section 4.2 shall be payable in cash by certified bank check or by wire
     -----------
transfer of immediately available funds.

          4.3  Rights of Inclusion.
               -------------------

          (a) No Stockholder shall, directly or indirectly, Transfer, in any
single transaction or series or related transactions to one or more Persons who
are not Affiliated Successors of such Stockholder (each such Person an
"Inclusion Event Purchaser") shares of Series C Preferred Stock or Common Stock
- --------------------------
(collectively, "Inclusion Stock") in circumstances in which, after giving effect
                ---------------
to such Transfer, whether acting alone or in concert with any other Stockholder
(such parties referred to herein as "Selling Stockholders") would result in such
                                     --------------------
Selling Stockholder(s) Transferring twenty-five percent (25%) or more of the
outstanding shares of Inclusion Stock outstanding on the date of such proposed
Transfer on a fully diluted basis (excluding for such purposes the Series A
Preferred Stock) (an "Inclusion Event"), unless the terms and conditions of such
                      ---------------
sale to such Inclusion Event Purchaser shall include an offer to AT&T PCS, the
Cash Equity Investors and the Management Stockholders other than the Selling
Stockholder (each, an "Inclusion Event Offeree") to Transfer to such Inclusion
                       -----------------------
Event Purchasers up to that number of shares of any class of Inclusion Stock
then Beneficially Owned by each Inclusion Event Offeree that bears the same
proportion to the total number of shares of Inclusion Stock at that time
Beneficially Owned (without duplication) by each such Inclusion Event Offeree as
the number of shares of Inclusion Stock being Transferred by the Selling
Stockholders (including shares of Inclusion Stock theretofore Transferred if in
any applicable series of related transactions) bears to the total number of
shares of Inclusion Stock at the time Beneficially Owned (without duplication)
by the Selling Stockholders (including shares of Inclusion Stock theretofore
Transferred if in any applicable series of related transactions).  If the
Selling Stockholders receive a bona fide offer from an Inclusion Event Purchaser
to purchase shares of Inclusion Stock in circumstances in which, after giving
effect to such sale would result in an Inclusion Event, and which offer such
Selling Stockholders wish to accept, the Selling Stockholders shall then cause
the Inclusion Event Purchaser's offer to be reduced to writing (which writing
shall include an offer to purchase shares of Inclusion Stock from each Inclusion
Event Offeree according to the terms and conditions set forth in this Section
                                                                      -------
4.3) and the Selling Stockholders shall send written notice of the Inclusion
- ---
Event Purchaser's offer (the "Inclusion Notice") to each Inclusion Event
                              ----------------
Offeree, which Inclusion Notice shall specify (i) the names of the Selling
Stockholders, (ii) the names and addresses of the proposed acquiring Person,
(iii) the amount of shares proposed to be Transferred and the price, form of
consideration and other terms

                                       22
<PAGE>

and conditions of such Transfer (including, if in a series of related
transactions, such information with respect to shares of Inclusion Stock
theretofore Transferred), (iv) that the acquiring Person has been informed of
the rights provided for in this Section 4.3 and has agreed to purchase shares of
                                -----------
Inclusion Stock in accordance with the terms hereof, and (v) the date by which
each other Selling Stockholder may exercise its respective rights contained in
this Section 4.3, which date shall not be less than thirty (30) days after the
     -----------
giving of the Inclusion Notice.  The Inclusion Notice shall be accompanied by a
true and correct copy of the Inclusion Event Purchaser's offer. At any time
within thirty (30) days after receipt of the Inclusion Notice, each Inclusion
Event Offeree may accept the offer included in the Inclusion Notice for up to
such number of shares of Inclusion Stock as is determined in accordance with
this Section 4.3, by furnishing written notice of such acceptance to each
     -----------
Selling Stockholder, and delivering, to an escrow agent (which shall be a bank
or a law or accounting firm designated by the Company), on behalf of the Selling
Stockholders, the certificate or certificates representing the shares of
Inclusion Stock to be sold pursuant to such offer by each Inclusion Event
Offeree, duly endorsed in blank, together with a limited power of attorney
authorizing the escrow agent, on behalf of the Inclusion Event Offeree, to sell
the shares to be sold pursuant to the terms of such Inclusion Event Purchaser's
offer.

          In the event that the Inclusion Event Purchaser does not agree to
purchase all of the shares of Inclusion Stock proposed to be sold by the Selling
Stockholders and the Inclusion Event Offeree, then each Selling Stockholder and
Inclusion Event Offeree shall have the right to sell to the Inclusion Event
Purchaser that number of shares of Inclusion Stock as shall be equal to (x) the
number of shares of Inclusion Stock which the Inclusion Event Purchaser has
agreed to purchase times (y) a fraction, the numerator of which is the number of
shares of Inclusion Stock Beneficially Owned (without duplication) by such
Selling Stockholder or Inclusion Event Offeree and the denominator of which is
the aggregate number of shares of Inclusion Stock Beneficially Owned (without
duplication) by all Selling Stockholders and Inclusion Event Offeree.  If any
Inclusion Event Offeree desires to sell less than its proportionate amount of
shares of Inclusion Stock that it is entitled to sell pursuant to this Section
                                                                       -------
4.3, then the Selling Stockholders and the remaining Inclusion Event Offeree
- ---
shall have the right to sell to the Inclusion Event Purchaser an additional
amount of shares of Inclusion Stock as shall be equal to (x) the number of
shares of Inclusion Stock not being sold by any such Inclusion Event Purchasers
times (y) a fraction, the numerator of which is the number of shares of
Inclusion Stock owned such Selling Stockholder or remaining Inclusion Event
Offeree and the denominator of which is the aggregate number of shares of
Inclusion Stock Beneficially Owned (without duplication) by all Selling
Stockholders and remaining Inclusion Event Offeree.  Such process shall be
repeated in series until all of the remaining Inclusion Event Offeree agree to
sell their remaining proportionate number of shares of Inclusion Stock.

          (b) The purchase from each Inclusion Event Offeree pursuant to this
Section 4.3 shall be on the same terms and conditions, including the price per
- -----------
share received by the Selling Stockholders and stated in the Inclusion Notice
provided to each Inclusion Event Offeree.  In the event that the Inclusion Stock
is Common Stock, all Inclusion Event Offeree shall be required, as a condition
of participating in such transaction, to convert its Preferred

                                       23
<PAGE>

Stock into Common Stock and Transfer Common Stock to the Inclusion Event
Purchaser.  In the event that the Inclusion Stock is Series C Preferred Stock
and after giving effect to the rights of the Inclusion Event Offeree to sell
their pro rata share of Series C Preferred Stock or Common Stock pursuant to
this Section 4.3 the Inclusion Event Purchaser shall be required to purchase
     -----------
both Series C Preferred Stock and Common Stock, the purchase price allocable to
holders of Series C Preferred Stock, on the one hand, and to holders of Common
Stock, on the other hand, shall be determined by an independent committee of the
Board of Directors selected from among those directors who were not designated
by any Selling Stockholders or Inclusion Event Offeree.

          (c) Simultaneously with the consummation of the sale of the shares of
Inclusion Stock of the Selling Stockholders and each Inclusion Event Offeree to
the Inclusion Event Purchaser pursuant to the Inclusion Event Purchaser's offer,
the Selling Stockholders shall notify each Inclusion Event Offeree and shall
cause the purchaser to remit to each Inclusion Event Offeree the total sales
price of the shares of Inclusion Stock held by each Inclusion Event Offeree sold
pursuant thereto and shall furnish such other evidence of the completion and
time of completion of such sale and the terms thereof as may be reasonably
requested by each Inclusion Event Offeree.

          (d) If within thirty (30) days after receipt of the Inclusion Notice,
an Inclusion Event Offeree has not accepted the offer contained in the Inclusion
Notice, such Inclusion Event Offeree shall be deemed to have waived any and all
rights with respect to the sale described in the Inclusion Notice (but not with
respect to any subsequent sale, to the extent this Section 4.3 is applicable to
                                                   -----------
such subsequent sale) and the Selling Stockholders shall have sixty (60) days in
which to sell not more than the number of shares of Inclusion Stock described in
the Inclusion Notice, on terms not more favorable to the Selling Stockholders
than were set forth in the Inclusion Notice; provided, however, that if such
purchase is subject to the consent of the FCC or any public service or public
utilities commission, the purchase of the Offered Shares shall be closed on the
first business day after all such consents shall have been obtained by Final
Order.

          4.4  Right of First Negotiation.  In the event that a Stockholder
               --------------------------
desires to Transfer any shares of Common Stock following the IPO Date in a
Transfer described in clauses (x), (y) or (z) of Section 4.1(b), such
                                                 --------------
Stockholder shall give written notice thereof to AT&T PCS, such notice to
specify, among other things, the number of shares that such Stockholder desires
to sell.  For the applicable first negotiation period hereinafter set forth,

permitted pursuant to Section 4.2 or Section 4.3, each transferee that is not a
                      -----------    -----------
party hereto shall, prior to such Transfer, agree in writing to be bound by all
of the provisions of this Agreement applicable to the Stockholders (and shall
thereby become a Stockholder for all purposes of this Agreement). Any Transfer

and such transferee shall have no rights as a Stockholder of the Company.

          (b) Notwithstanding anything to the contrary contained in this

                  --------------
Common Stock by a Stockholder after the IPO Date pursuant to an underwritten
Registration or in accordance with the provisions of Rule 144.  It shall be
deemed a breach of this Section 4.5(b) by a Stockholder Beneficially Owning more
                        --------------
than 10% of the Common Stock outstanding if any Prohibited Transferee shall

the sole owner of such shares, and has good and valid title to such shares, free
and clear of any and all Liens (other than pursuant to this Agreement, the
Restated Certificate or any Related Agreement), and that the sale of such shares
does not violate any agreement to which it is a party or by which it is bound.

          4.7  Stop Transfer.
               -------------

          (a) The Company agrees not to effect any Transfer of shares of Company
Stock by any Stockholder whose proposed Transfer is subject to Sections 4.2, 4.3
                                                               -----------------
or 4.4 until it has received evidence reasonably satisfactory to it that the
- ------
rights provided to any other Stockholders pursuant to such Sections, if
applicable to such Transfer, have been complied with and satisfied in all
respects.  If any portion of such Stockholder's Unfunded Commitment shall remain
unpaid on the date of such proposed Transfer, then, as a condition of such
Transfer, such Person purchasing such Company Stock shall, or another Cash

Prohibited Transferee except that purchases of Common Stock by a Prohibited
Transferee in connection with a Registration of Common Stock shall not
constitute a violation of this Section 4.7(b).

     5.   Registration Rights.
          -------------------

               (a)  Demand Registration Rights.
                    --------------------------

          (i) Right to Demand Registration.  From and after the ninety-first
              ----------------------------
(91st) day following the IPO Date (or such longer period as may be required by
the managing underwriters of the Company's initial public offering) and, subject
to Section 4.1(d), each of (A) AT&T PCS, (B) a Qualified Holder, and (C)
   --------------
Management Stockholders that in the aggregate Beneficially Own at least 50.1% of
the shares of Common Stock then Beneficially

                                       26

Owned by the Management Stockholders (each a "Demanding Stockholder" and,
                                              ---------------------
collectively, the "Demanding Stockholders") shall have the right to make a
                   ----------------------
written request to the Company for registration with the Commission, under and
in accordance with the provisions of the Securities Act, of all or part of their
Registrable Securities pursuant to an underwritten offering (a "Demand
                                                                ------
Registration"), which request shall specify the number of Registrable Securities
- ------------
proposed to be sold by each Demanding Stockholder; provided, however, that (x)
the Company need not effect a Demand Registration unless the sale of the
Registrable Securities proposed to be sold by the Demanding Stockholder shall
reasonably be expected to result in aggregate gross proceeds to such Demanding
Stockholder of at least $10 million, and (y) if the Board of Directors
determines that a Demand Registration would interfere with any pending or
contemplated material acquisition, disposition, financing or other material
transaction, the Company may defer a Demand Registration (including by
withdrawing any Registration Statement filed in connection with a Demand
Registration); so long as that the aggregate of all such deferrals shall not
exceed one hundred twenty (120) days in any 360 day period.  Demand Registration
shall not be deemed a Demand Registration hereunder until such Demand
Registration has been declared effective by the Commission (without interference
by any stop order, injunction or other order or requirement of the Commission or
other governmental agency, for any reason), and maintained continuously
effective for a period of at least three (3) months or such shorter period when
all Registrable Securities included therein have been sold in accordance with
such Demand Registration; provided, however, that a Qualified Holder may, not
more frequently than once in any twelve (12) month period, request that the
Demand Registration be a shelf registration that is maintained continuously
effective for a period of at least six (6) months or such shorter period when
all Registrable Securities included therein have been sold in accordance with
such Demand Registration.  A Demanding Stockholder may make a written request
for a Demand Registration in accordance with the foregoing in respect of Equity
Securities that it intends to convert into shares of Common Stock upon the
effectiveness of the Registration Statement prepared in connection with such
demand, and the Company shall fulfill its obligations under this Section 5 in a
                                                                 ---------
manner that permits such Demanding Stockholder to exercise its conversion rights
in respect of such Equity Securities and substantially contemporaneously sell
the shares of Common Stock issuable upon such conversion under such Registration
Statement.

          The Company will not be obligated to effect more than two (2) separate
Demand Registrations during any twelve (12) month period; provided, however,
that only one (1) request for a Demand Registration may be exercised by AT&T PCS
and/or Management Stockholders that in the aggregate Beneficially Own at least
50.1% of the shares of Common Stock then Beneficially Owned by the Management
Stockholders during any twelve (12) month period.

          Within ten (10) days after receipt of the request for a Demand
Registration, the Company will send written notice (the "Demand Notice") of such
                                                         -------------
Registration request and its intention to comply therewith to all Stockholders
who are holders of Registrable Securities and, subject to Section 5(a)(ii), the

Company will include in such Demand Registration all Registrable Securities of
such Stockholders with respect to which the Company has received written
requests

                                       27
<PAGE>

for inclusion therein within twenty (20) days after the last date such
Demand Notice was deemed to have been given pursuant to Section 12.1.
                                                        ------------

          (ii) Priority on Demand Registration.  If the managing underwriter
               -------------------------------
or underwriters advise the Company and the holders of the Registrable Securities
to be registered in writing that in its or their opinion that, the number of
Registrable Securities proposed to be sold in such Registration and any other
securities of the Company requested or proposed to be included in such
Registration exceeds the number that can be sold in such offering without (A)
creating a substantial risk that the proceeds or price per share that will be
derived from such Registration will be reduced or that the number of Registrable
Securities to be registered is too large a number to be reasonably sold, or (B)
materially and adversely affecting such Registration in any other respect, the
Company will (x) include in such Registration the aggregate number of
Registrable Securities recommended by the managing underwriter (the number of
Registrable Securities to be registered for each Stockholder to be reduced pro
rata based on the amount of Registrable Securities each of the Stockholders
requested to be included in such Registration), and (y) not allow any securities
s other than Registrable Securities to be included in such Registration unless
all Registrable Securities requested to be included shall have been included
therein, and then only to the extent recommended by the managing underwriter or
determined by the Company after consultation with an investment banker of
nationally recognized standing (notification of which number shall be given by
the Company to the holders of Registrable Securities).

          (iii) Selection of Underwriters.  The offering of such Registrable
               -------------------------
Securities pursuant to such Demand Registration shall be in the form of an
underwritten offering.  The Demanding Stockholder that initiated such Demand
Registration will select a managing underwriter or underwriters of recognized
national standing to administer the offering, which managing underwriter or
underwriters shall be reasonably acceptable to the Company.

               (b) Piggyback Registration Rights.
                   -----------------------------

          (i) Right to Piggyback.  If the Company proposes to register any
              ------------------
shares of Common Stock (or securities convertible into or exchangeable for
Common Stock) with the Commission under the Securities Act (other than a
Registration on Form S-4 or Form S-8, or any successor forms), and the
Registration form to be used may be used for the Registration of the Registrable
Securities (a "Piggyback Registration"), the Company will give written notice (a
               ----------------------
"Piggyback Notice") to all Stockholders, at least thirty (30) days prior to the
 ----------------
anticipated filing date, of its intention to effect such a Registration, which
notice will specify the proposed offering price (if determined at that time),
the kind and number of securities proposed to be registered, the distribution
arrangements and will, subject to Section 5(b)(ii), include in such Piggyback
                                  ----------------
Registration all Registrable Securities with respect to which the Company has
received written requests (which requests have not been withdrawn) for inclusion
therein within twenty (20) days after the last date such Piggyback Notice was
deemed to have been given pursuant to Section 12.1.

                                       28
<PAGE>

If at any time after giving the Piggyback Notice and prior to the effective date
of the Registration Statement filed in connection with such Registration, the
Company determines for any reason not to register or to delay Registration, the
Company may, at its election, give written notice of such determination to each
holder of Registrable Securities that has requested inclusion of Registrable
Securities in such Registration and (A) in the case of a determination not to
register, shall be relieved of its obligation to register any Registrable
Securities in connection with such Registration, and (B) in the case of a
determination to delay registering, shall be permitted to delay registering any
Registrable Securities for the same period as the delay in registering such
other securities.

          (ii) Priority on Piggyback Registrations.  If the managing underwriter
               -----------------------------------
or underwriters, if any, advise the Company and the holders of Registrable
Securities in writing that in its or their opinion, that the number or kind of
securities proposed to be sold in such Registration (including Registrable
Securities to be included pursuant to Section 5(b)(i)) exceeds the number that
                                      ----------------
can be sold in such offering without (A) creating a substantial risk that the
proceeds or price per share the Company will derive from such Registration will
be reduced, or that the number of shares to be registered is too large a number
to be reasonably sold or (B) materially and adversely affecting such
Registration in any other respect, without any reduction in the amount of
securities the Company proposes to issue and sell for its own account or in the
amount of securities any other security holder proposes to sell for its own
account pursuant to a demand Registration right, the number of Registrable
Securities to be registered for each Demanding Stockholder shall be reduced pro
                                                                            ---
rata based on the amount of Registrable Securities each of the Demanding
- ----
Stockholders requested to be included in such Registration, to the extent
necessary to reduce the number of Registrable Securities to be registered to the
number recommended by the managing underwriter or determined by the Company
after consultation with an investment banker of nationally recognized standing
(notification of which number shall be given by the Company to the holders of
Registrable Securities of such determination).

          (c) Selection of Underwriters.  Except as set forth in Section
              -------------------------                          -------
5.1(a)(iii), the Company (by action of the Board of Directors) will select a
- -----------
managing underwriter or underwriters to administer the offering, which managing
underwriter or underwriters will be of nationally recognized standing.

respect to the Registration Statement or any post-effective amendment, when the
same has become effective; (B) of any request by the Commission for amendments

offerings; and (D) deliver such documents and certificates as may be reasonably
requested by the holders of a majority of the Registrable Securities being sold
and the managing underwriters, if any, to evidence compliance with subsection
(xi) above and with any customary conditions contained in the underwriting
agreement or other agreement entered into by the Company.  All the above in this
Section 5(d)(xiv) shall be done at each closing under each underwriting or
- -----------------
similar agreement or as and to the extent required thereunder;

          (xv) make available for inspection by a representative of each
Demanding Stockholder, any underwriter participating in any disposition pursuant
to such Registration, and any attorney or accountant retained by the sellers or
underwriter, copies or extracts of all financial and other records, pertinent
corporate documents and properties of the Company as shall be reasonably
necessary, in the opinion of the holders' or underwriter's counsel, to enable
them to fulfill their due diligence responsibilities; and cause the Company's
officers, directors and employees to supply all information reasonably requested
by any such representative, underwriter, attorney or accountant in connection
with such Registration Statement; provided, however, that the Company shall not
be required to comply with this paragraph (xv) unless such person executes
confidentiality agreements whereby such person agrees that any records,
information or documents that are designated by the Company in writing as
confidential shall be kept confidential by such Persons and used only in
connection with the proposed Registration unless disclosure of such records,
information or documents is required by court or administrative order or any
regulatory body having jurisdiction; and each seller of Registrable Securities
agrees that it will, upon learning that disclosure of such records, information
or documents is sought in a court of competent jurisdiction or by a governmental
agency, give notice to the Company and allow the Company, at the Company's
expense, to undertake appropriate action to prevent disclosure of any records,
information or documents deemed confidential; provided further, however,
notwithstanding any designation of confidentiality by the Company, confidential
information shall not include information which (i) becomes generally available
to the public other than as a result of a disclosure by or on behalf of any such
Person, or (ii) becomes available to any such Person on a non-confidential basis
from a source other than the Company or its advisors, provided that such source
is not to such Person's knowledge bound by a confidentiality agreement with or
other obligations of secrecy to the Company or another party with respect to
such information;

          (xvi) otherwise use its reasonable best efforts to comply with all
applicable rules and regulations of the Commission, and make generally available
to its security holders, earnings statements satisfying the provisions of
Section 11(a) of the Securities Act, no later than forty-five (45) days after
the end of any twelve (12)-month period (or ninety (90) days, if such period is
a fiscal year) (A) commencing at the end of any fiscal quarter in which

                                       33
<PAGE>

Registrable Securities are sold to underwriters in a firm or best efforts
underwritten offering, or (B) if not sold to underwriters in such an offering,
beginning with the first month of the Company's first fiscal quarter commencing
after the effective date of the Registration Statement, which statements shall
cover said twelve (12)-month periods; and

          (xvii) promptly prior to the filing of any document that is to be
incorporated by reference into any Registration Statement or Prospectus (after
initial filing of the Registration Statement), provide copies of such document
to counsel to the selling holders of Registrable Securities and to the managing
underwriters, if any, make the Company's executive officers and other
representatives available for discussion of such document and make such changes
in such document prior to the filing thereof as counsel for such selling holders
or underwriters may reasonably request.

     The Company may require each seller of Registrable Securities as to which
any Registration is being effected to furnish to the Company such information
regarding the proposed distribution of such securities as the Company may from
time to time reasonably request in writing.  Each holder of Registrable
Securities agrees by acquisition of such Registrable Securities that, upon
receipt of any notice from the Company of the happening of any event of the kind
described in Section 5(d)(xi), such holder shall forthwith discontinue
             ----------------
disposition of Registrable Securities until such holder's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 5(d)(xi), or
                                                          ----------------
until it is advised in writing (the "Advice") by the Company that the use of the
                                     ------
Prospectus may be resumed, and has received copies of any additional or
supplemental filings that are incorporated by reference in the Prospectus; and,
if so directed by the Company, such holder shall deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
seller's possession, of the Prospectus covering such Registrable Securities
current at the time of receipt of such notice.  In the event the Company gives
any such notice, the time periods regarding the maintenance of the effectiveness
of any Registration Statement in Sections 5(d)(ii) shall be extended by the
                                 -----------------
number of days during the period from and including the date of the receipt of
such notice pursuant to Section 5(d)(iii)(F) hereof to and including the date
                        --------------------
when each seller of Registrable Securities covered by such Registration
Statement shall have received the copies of the supplemented or amended
prospectuses contemplated by Section 5(d)(xi) or the Advice.
                             ----------------

               (e)  Indemnification.
                    ----------------

          (i) In the event of the Registration or qualification of any
Registrable Securities under the Securities Act or any other applicable
securities laws pursuant to the provisions of this Section 5, the Company agrees
                                                   ---------
to indemnify and hold harmless each Stockholder thereby offering such
Registrable Securities for sale (an "Indemnified Stockholder"), underwriter,
                                     -----------------------
broker or dealer, if any, of such Registrable Securities, and each other person,
if any, who controls any such Indemnified Stockholder, underwriter, broker or
dealer within the meaning of the Securities Act or any other applicable
securities laws, from and against any and all losses, claims, damages, expenses
or liabilities (or actions in respect thereof), joint or several,

                                       34
<PAGE>

to which such Indemnified Stockholder, underwriter, broker or dealer or
controlling person may become subject under the Securities Act or any other
applicable federal or state securities laws or otherwise, insofar as such
losses, claims, damages, expenses or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in any Registration Statement under which such
Registrable Securities were registered or qualified under the Securities Act or
any other applicable securities laws, any preliminary prospectus or final
prospectus relating to such Registrable Securities, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by the
Company of any rule or regulation under the Securities Act or any other
applicable federal or state securities laws applicable to the Company or
relating to any action or inaction required by the Company in connection with
any such Registration or qualification, and will reimburse each such Indemnified
Stockholder, underwriter, broker or dealer and each such controlling person for
any legal or other expenses reasonably incurred by such Indemnified Stockholder,
underwriter, broker or dealer or controlling person in connection with
investigating or defending any such loss, claim, damage, expense, liability or
action; provided, however, that the Company will not be liable in any such case
to the extent that any such loss, claim, damage, expense or liability arises out
of or is based upon an untrue statement or omission contained in such
Registration Statement, such preliminary prospectus, such final prospectus or
such amendment or supplement thereto, made in reliance upon and in conformity
with written information furnished to the Company by such Indemnified
Stockholder, underwriter, broker, dealer or controlling person specifically and
expressly for use in the preparation thereof or by the failure of such
Indemnified Stockholder, underwriter, broker or dealer, or controlling person to
deliver a copy of the Registration Statement, such preliminary prospectus, such
final prospectus or such amendment or supplement thereto after the Company has
furnished such party with a sufficient number of copies of the same and such
party failed to deliver or otherwise provide a copy of the final prospectus to
the person asserting an untrue statement or omission or alleged untrue statement
or omission at or prior to the written confirmation of the sale of securities to
such person, if such statement or omission was in fact corrected in such final
prospectus.

          (ii) In the case of an underwritten offering in which the Registration
Statement covers Registrable Securities, the Company agrees to enter into an
underwriting agreement in customary form and substance with such underwriters
and to indemnify the underwriters, their officers and directors, if any, and
each person, if any, who controls such underwriters within the meaning of
Section 15 of the Securities Act and Section 20 of the Exchange Act, to the same
extent as provided in the preceding paragraph with respect to the
indemnification of the holders of Registrable Securities; provided, however, the
Company shall not be required to indemnify any such underwriter, or any officer
or director of such underwriter or any person who controls such underwriter
within the meaning of Section 15 of the Securities Act and Section 20 of the
Exchange Act, to the extent that the loss, claim, damage, expense or liability
(or actions in respect thereof) for which indemnification is sought results from
such underwriter's failure to deliver or otherwise provide a copy of the final
prospectus to

                                       35
<PAGE>

the person asserting an untrue statement or omission or alleged untrue statement
or omission at or prior to the written confirmation of the sale of securities to
such person, if such statement or omission was in fact corrected in such final
prospectus.

          (iii) In the event of the Registration or qualification of any
Registrable Securities of the Stockholders under the Securities Act or any other
applicable federal or state securities laws for sale pursuant to the provisions
hereof, each Indemnified Stockholder agrees severally, and not jointly, to
indemnify and hold harmless the Company, each person who controls the Company
within the meaning of the Securities Act, and each officer and director of the
Company from and against any losses, claims, damages, expenses or liabilities
(or actions in respect thereof), joint or several, to which the Company, such
controlling person or any such officer or director may become subject under the
Securities Act or any other applicable securities laws or otherwise, insofar as
such losses, claims, damages, expenses or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement of any material
fact contained in any Registration Statement under which such Registrable
Securities were registered or qualified under the Securities Act or any other
applicable securities laws, any preliminary prospectus or final prospectus
relating to such Registrable Securities, or any amendment or supplement thereto,
or arise out of or are based upon an untrue statement therein or the omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, which untrue statement or omission was
made therein in reliance upon and in conformity with written information
furnished to the Company by such Indemnified Stockholder specifically and
expressly for use in connection with the preparation thereof, and will reimburse
the Company, such controlling person and each such officer or director for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, expense, liability or
action; provided, however, an Indemnified Stockholder's liability under this
Section 5(e)(iii) shall not exceed the net proceeds received by such Indemnified
- -----------------
Stockholder with respect to the sale of any Registrable Securities.

          (iv) In the case of an underwritten offering of Registrable
Securities, each holder of a Registrable Security included in a Registration
Statement shall agree to enter into an underwriting agreement in customary form
and substance with such underwriters, and to indemnify such underwriters, their
officers and directors, if any, and each person, if any, who controls such
underwriters within the meaning of Section 15 of the Securities Act and Section
20 of the Exchange Act, to the same extent as provided in the preceding
paragraph with respect to indemnification by such holder of the Company, but
subject to the same limitation as provided in Section 5(e)(ii) with respect to
                                              ----------------
indemnification by the Company of such underwriters, officers, directors and
control persons.

          (v) Promptly after receipt by a person entitled to indemnification
under this Section 5(e) (an "Indemnified Party") of notice of the commencement
           ------------      -----------------
of any action or claim relating to any Registration Statement filed under this
Section 5 as to which indemnity may be sought hereunder, such Indemnified Party
- ---------
will, if a claim for indemnification hereunder in respect thereof is to be made
against any other party hereto (an

                                       36
<PAGE>

"Indemnifying Party"), give written notice to each such Indemnifying Party of
 ------------------
the commencement of such action or claim, but the omission to so notify each
such Indemnifying Party will not relieve any such Indemnifying Party from any
liability which it may have to any Indemnified Party otherwise than pursuant to
the provisions of this Section 5(e) and shall also not relieve any such
                       ------------
Indemnifying Party of its obligations under this Section 5(e) except to the
                                                 ------------
extent that any such Indemnifying Party is actually prejudiced thereby.  In case
any such action is brought against an Indemnified Party, and such Indemnified
Party notifies an Indemnifying Party of the commencement thereof, such
Indemnifying Party will be entitled (at its own expense) to participate in and,
to the extent that it may wish, jointly with any other Indemnifying Party
similarly notified, to assume the defense, with counsel reasonably satisfactory
to such Indemnified Party, of such action and/or to settle such action and,
after notice from the Indemnifying Party to such Indemnified Party of its
election so to assume the defense thereof, the Indemnifying Party will not be
liable to such Indemnified Party for any legal or other expenses subsequently
incurred by such Indemnified Party in connection with the defense thereof, other
than the reasonable cost of investigation; provided, however, that no
Indemnifying Party shall consent to the entry of any judgment or enter into any
settlement agreement without the prior written consent of the Indemnified Party
unless such Indemnified Party is fully released and discharged from any such
liability, and no Indemnified Party shall consent to the entry of any judgment
or enter into any settlement of any such action the defense of which has been
assumed by an Indemnifying Party without the consent of each Indemnifying
Party.  Notwithstanding the foregoing, the Indemnified Party shall have the
right to employ its own counsel in any such case, but the fees and expenses of
such counsel shall be at the expense of such Indemnified Party unless (a) the
employment of such counsel shall have been authorized in writing by the
Indemnifying Party in connection with the defense of such suit, action, claim or
proceeding; (b) the Indemnifying Party shall not have employed counsel
(reasonably satisfactory to the Indemnified Party) to take charge of the defense
of such action, suit, claim or proceeding; or (c) such Indemnified Party shall
have reasonably concluded, based upon the advice of counsel, that there may be
defenses available to it which are different from or additional to those
available to the Indemnifying Party which, if the Indemnifying Party and the
Indemnified Party were to be represented by the same counsel, could result in a
conflict of interest for such counsel or materially prejudice the prosecution of
the defenses available to such Indemnified Party.  If any of the events
specified in clauses (a), (b) or (c) of the preceding sentence shall have
occurred or shall otherwise be applicable, then the fees and expenses of one
counsel or firm of counsel selected by a majority in interest of the indemnified
parties (and reasonably acceptable to the Indemnifying Party) shall be borne by
the Indemnifying Party.  If, in any such case, the Indemnified Party employs
separate counsel, the Indemnifying Party shall not have the right to direct the
defense of such action, suit, claim or proceeding on behalf of the Indemnified
Party and the Indemnified Party shall assume such defense and/or settle such
action; provided, however, that an Indemnifying Party shall not be liable for
the   settlement of any action, suit, claim or proceeding effected without its
prior written consent, which consent shall not be unreasonably withheld.

                                       37
<PAGE>

          The provisions of this Section 5(e) shall be in addition to any
                                 ------------
liability which any party may have to any other party and shall survive any
termination of this Agreement.

          (f) Contribution.  If for any reason the indemnification provided for
              ------------
in Section 5(e)(i) or 5(e)(iii) is unavailable to an Indemnified Party as
   ----------------------------
contemplated therein, then the Indemnifying Party, in lieu of indemnification
shall contribute to the amount paid or payable by the Indemnified Party as a
result of such loss, claim, damage, expense or liability (or action in respect
thereof) in such proportion as is appropriate to reflect not only the relative
benefits received by the Indemnified Party and the Indemnifying Party, but also
the relative fault of the Indemnified Party and the Indemnifying Party, as well
as any other relevant equitable considerations, provided that no Stockholder
shall be required to contribute in an amount greater than the difference between
the net proceeds received by such Stockholder with respect to the sale of any
Registrable Securities and all amounts already contributed by such Stockholder
with respect to such claims, including amounts paid for any legal or other fees
or expenses incurred by such Stockholder.  No person guilty of a fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of any such
fraudulent misrepresentation.  The relative fault of such Indemnifying Party and
Indemnified Party shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such Indemnifying Party or
Indemnified Party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action.

          (g) Registration Expenses.  Except as hereinafter provided, all
              ---------------------
expenses incident to the Company's performance of or compliance with this
Section 5 will be borne by the Company, including, without limitation, all
- ---------
Registration and filing fees under the Securities Act and the Exchange Act, the
fees and expenses of the counsel and accountants for the Company (including the
expenses of any "cold comfort" letters and special audits required by or
incident to the performance of such persons), all other costs and expenses of
the Company incident to the preparation, printing and filing under the
Securities Act of the Registration Statement (and all amendments and supplements
thereto), and furnishing copies thereof and of the Prospectus included therein,
all out-of-pocket expenses of underwriters customarily paid for by issuers to
the extent provided for in any underwriting agreement, the costs and expenses
incurred by the Company in connection with the qualification of the Registrable
Securities under the state securities or "blue sky" laws of various
jurisdictions, the costs and expenses associated with filings required to be
made with the NASD, the costs and expenses of listing the Registrable Securities
for trading on a national securities exchange or authorizing them for trading on
NASDAQ and all other costs and expenses incurred by the Company in connection
with any Registration hereunder.  In addition, the Company shall pay or
reimburse the sellers of Registrable Securities the reasonable fees and expenses
of one attorney to such sellers incurred in connection with a registration
(collectively, with the expenses referred to in the immediately preceding
sentence, the "Registration Expenses").  Except as provided in the immediately
               ---------------------

                                       38
<PAGE>

preceding sentence, each Stockholder shall bear the costs and expenses of any
underwriters' discounts and commissions, brokerage fees or transfer taxes
relating to the Registrable Securities sold by such Stockholder and the fees and
expenses of any attorneys, accountants or other representatives retained by the
Stockholder.

          (h) Participation in Underwritten Registrations.  No Stockholder may
              -------------------------------------------
participate in any underwritten Registration hereunder unless such Stockholder
(i) agrees to sell its Registrable Securities on the basis provided in any
customary and reasonable underwriting arrangements approved by the persons
entitled hereunder to select the underwriter, and (ii) accurately completes in a
timely manner and executes all questionnaires, powers of attorney, underwriting
agreements, indemnities and other documents customarily required under the terms
of such underwriting arrangements.

               (i)  Holdback Agreements.
                    -------------------

          (i) Each holder of Registrable Securities whose securities are
included in a Registration Statement agrees not to effect any public sale or
distribution of the issue being registered or a similar security of the Company,
or any securities convertible into or exchangeable or exercisable for such
securities, including a sale pursuant to Rule 144 or Rule 144A under the
Securities Act, during the fifteen (15) days prior to, and during the ninety
(90)-day period (or such longer period as requested by the managing underwriter
or underwriters in the case of an underwritten public offering) beginning on,
the effective date of such Registration Statement (except as part of such
Registration), if and to the extent requested by the managing underwriter or
underwriters in an underwritten public offering.

          (ii) The Company agrees not to effect any public sale or distribution
of the issue being registered or a similar security of the Company, or any
securities convertible into or exchangeable or exercisable for such securities
(other than any such sale or distribution of such securities in connection with
any merger or consolidation by the Company or any Subsidiary or the acquisition
by the Company or any Subsidiary of the capital stock or substantially all of
the assets of any other Person), during the fifteen (15) days prior to, and
during the ninety (90)-day period beginning on, the effective date of each
Demand Registration.

          (j) Public Information Reporting.  The Company hereby covenants and
              ----------------------------
agrees to and with the Stockholders that at all times following the IPO Date it
shall provide and file such financial and other information concerning the
Company as may from time to time be required by the Commission and any other
governmental authority having jurisdiction, so as to comply with all reporting
requirements under the Exchange Act, and shall, upon request, state in writing
that it has complied with all such requirements, and further agrees that, for so
long as (following the IPO Date) the Company is not subject to Section 13 or
15(d) of the Exchange Act, the Company shall comply in all respects with
paragraph (c)(2) of Rule 144.

or consolidation of the Company or such Subsidiary with or into any other entity
(regardless of whether the Company or such Subsidiary is the surviving entity in
any such transaction) (any such merger, combination or consolidation is referred
to as a "Company Merger"), (ii) any sale or disposition of a substantial portion
         --------------
of its assets (a "Company Asset Sale"), or (iii) the liquidation, dissolution or

subject to a right of first offer in accordance with the provisions of Section
                                                                       -------

written notice (the "Sale Notice") to AT&T PCS.  Each Sale Notice shall describe
                     -----------
in reasonable detail all material terms of the proposed Sale Transaction.  The

AT&T PCS shall have the irrevocable right and option, but not the obligation, to
accept the Sale Offer in whole but not in part by giving written notice of its
acceptance of such offer within thirty (30) days of the date of the Sale Notice
is given.  The Sale Transaction shall be closed at the principal executive
offices of the Company within thirty (30) days after the acceptance by AT&T PCS
of the Sale Offer; provided, however, that, if the Sale  Transaction is subject
to the consent of the FCC or any public service or public utilities commission,
the Sale Transaction shall be closed on the fifth business day after all such
consents shall have been obtained by Final Order.  If AT&T PCS declines (which
shall include the failure to give timely notice of acceptance) to accept the
Sale Offer, the Company shall have the right

                                       43

day acceptance period referred to above) to close a Sale Transaction on the
terms described in the Sale Offer (except that the price must be at least 95% of
the price set forth in the Sale Offer); provided, however, that, if the consent
of the FCC or any public service or public utilities commission is required, the
Sale Transaction may be closed not later than the fifth business day after all
such consents shall have been obtained by Final Order. If, after giving a Sale
Offer, the Company does not close a Sale Transaction in accordance with the
terms of the immediately preceding sentence, the Company shall not effect any
Sale Transaction without giving another Sale Notice in accordance with this
Section 7.4(d).

          7.5  Wholly-Owned Subsidiaries.  All of the Company's Subsidiaries

transfer, encumber or otherwise dispose of any shares of capital stock of any of
the Company's Subsidiaries to any Person other than the Company and its direct
or indirect wholly owned Subsidiaries, except for a pledge of any such shares in
connection with the incurrence of indebtedness.

shall not disclose such information, and shall cause its Representatives not to
disclose such information, to anyone except such Affiliates, Representatives or

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, however, 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.

the Company at least thirty (30) days prior to entering into a binding agreement
to sell such AT&T PCS Retained Licenses in the Territory such notice to specify
among other things, the AT&T PCS Retained Licenses in the Territory that it

given, the Company shall have the right to negotiate with AT&T PCS with respect
to the purchase of all, but not less than all, of such AT&T Retained Licenses in
the Territory; it being understood and agreed that such right shall not be
deemed to be a right of first offer or right of first refusal for the benefit of
the Company and AT&T PCS shall have the right to reject any offer made by the
Company during such thirty (30) day period.  In the event no binding agreement
to sell all or any of such AT&T PCS Retained Licenses in the Territory is
entered into prior to the expiration of the one hundred and eighty (180) day
period following the expiration of such (30) day period, such Licenses shall
become subject once again to the provision and restrictions hereof.

"Permitted Cellular License") authorizing the holder to provide in a specified

geographic area using specified frequencies in respect of which the Board of
Directors has determined that the acquisition of such License (and any other
assets being acquired together therewith) is a demonstrably superior alternative
to constructing a PCS System in the applicable area within the PCS Territory,
provided that, (i) a majority of the POPs  included in the geographic area
covered by such License are within the PCS Territory, (ii) none of AT&T PCS, any
Affiliate thereof or any AT&T Licensee owns an interest in an FCC License to
provide Commercial Mobile Radio Service in such geographic area, and (iii) the
ownership of such License will not conflict with, or cause AT&T PCS, any
Affiliate thereof or any AT&T Licensee to be in violation or breach of any
agreement, instrument, Law or License applicable to or binding upon such Person

Permitted Cellular License if the acquisition of such License would adversely
affect the Company's ability to satisfy its obligations under the first sentence

     8.   Operating Arrangements.
          ----------------------

          8.1  Construction of Company Systems.
               -------------------------------

          (a) The Company hereby agrees to construct, or cause its Subsidiaries
to construct, Company Systems covering the Territory on a schedule no less rapid
than is set forth in the Minimum Build-Out Plan.  Company Systems shall be
technologically compatible in all material respects with systems being used in a
Majority of the Southeast Region (including without limitation for the purpose
of facilitating roaming and handoff between systems), and will to the extent
technologically feasible implement the same User Interface as such systems, with
the intention that the User Interface in Company Systems will not differ from
the User Interface in a Majority of the Southeast Region in a manner that would
be material to customers.

          (b) The Company and AT&T PCS hereby agree that the Company shall
assume and be obligated to satisfy the construction requirements set forth in 47
CFR (S)24.203 with respect to the AT&T PCS Retained Licenses in the Territory
and the AT&T PCS Contributed Licenses.  The Company and AT&T PCS agree from time
to time at the request of the Company or AT&T PCS, as applicable, to provide the
other with information concerning the status of construction of its PCS Systems
to enable such party to determine the level of compliance with such construction
requirements with respect to the AT&T PCS Retained Licenses and AT&T PCS
Contributed Licenses, as applicable.

          (c) The Company will arrange for all necessary microwave relocation in
connection with the AT&T PCS Contributed Licenses and pay, assume or (if
applicable) reimburse AT&T PCS or its Affiliates for any obligation to pay, any
reasonable costs incurred by it or AT&T PCS in connection with any such
microwave relocation, provided, that nothing contained herein shall require the
Company to pay any costs incurred in connection with microwave relocation in
connection with the AT&T PCS Retained Licenses.

          8.2  Service Features.  Company Systems will offer the Core Service
               ----------------
Features. Company Systems will also offer, at the written request of AT&T PCS,
additional service features that AT&T PCS has notified the Company it will
provide in a Majority of the Southeast Region, unless the Board of Directors
reasonably determines that the provision of such additional features would be
financially detrimental to the Company.  Unless the Board of Directors makes
such a determination, any such additional features shall be adopted within one
hundred twenty (120) days after the request by AT&T PCS.  The Critical Network
Elements are set forth on Schedule XI.
                          -----------

          8.3  Quality Standards.  The Company shall use commercially reasonable
               --------------------
efforts to cause the Company Systems to comply with the TDMA Quality Standards.
Without limiting the foregoing, with respect to each material portion of a
Company System (such as a city) that the Company places in commercial service,
on or prior to the first anniversary of the date such material portion is placed
in commercial service, the Company shall cause each such material portion to
achieve a level of compliance with the TDMA Quality Standards equal to at least
the average level of compliance achieved by comparable PCS and Cellular Systems
owned and operated by AT&T PCS taking into account, among other things, the
relative stage of development thereof.  In the event that the Company fails to
achieve such level of compliance, the Company shall not be deemed to be in
material breach of this provision if such noncompliance is cured within thirty
(30) days of notice thereof from AT&T PCS to the Company, or, if such breach is
not capable of being cured within such thirty (30) day period using commercially
reasonable efforts, within one hundred eighty (180) days of such notice,
provided the Company is using commercially reasonable efforts to cure such
material breach as soon as reasonably practicable.

          8.4  No Change of Business.
               ---------------------

               (a) Subject to Section 7.11, the Company will not, and will not
                              ------------
permit any of its Subsidiaries to, without obtaining the prior written consent
of AT&T PCS, do any of the following: (i) conduct, directly or indirectly, any
business other than the Business, (ii) make any material change to the Minimum
Build Out Plan in the Territory, or (iii) effect any transaction, agreement or
arrangement which has or could reasonably be expected to have the effect of
materially impairing or materially limiting the ability of (x) subscribers to
Cellular Systems and PCS Systems in which AT&T PCS or its Affiliates have an
ownership interest to utilize the Company Systems for roaming, or (y) AT&T PCS
or its Affiliates to resell wireless service on the Company Systems; it being
understood that clause (i) shall not be deemed to restrict the business of the
Company in any Overlap Territory.

               (b)  [Intentionally Omitted]

               (c) If at any time during the term of this Agreement AT&T PCS and

States: (i) the

Company will have the right to cease to use TDMA and may adopt the new
technology adopted by AT&T PCS and its Affiliates in a Majority of the United
States or implement any other alternative technology in Company Systems, and, if
it exercises such right, the definition of Company Systems shall be
automatically deemed to be modified by substituting a reference to such new or
alternative technology in lieu of the reference in such definition to TDMA, and
(ii) the obligations of AT&T PCS and its Affiliates pursuant to Section 8.6
                                                                -----------
shall terminate and be of no further force or effect, unless within sixty (60)
days of notice by AT&T PCS to the Company specifying that AT&T PCS and its
Affiliates have determined to discontinue use of TDMA in a Majority of the
United States, the Company agrees to implement in Company Systems on a
reasonable schedule the new technology adopted by AT&T PCS and its Affiliates in
a Majority of the United States.  In the event AT&T PCS desires to test any
technology that is an alternative to TDMA in any PCS System or Cellular System
contiguous to the Territory, AT&T PCS hereby agrees to notify the Company at
least thirty (30) days before conducting such test and will conduct such tests
in a manner that does not have a material adverse effect on the Company.

          8.5  Preferred Provider.
               ------------------

               (a) The Company and its Subsidiaries shall not market, offer,
provide or resell interexchange services, except (i) interexchange services that
constitute Company Communication Services and (ii) interexchange services
procured from AT&T Corp. or an Affiliate thereof designated by AT&T Corp. Such
interexchange services shall be provided by AT&T Corp. or such Affiliate at a
reasonable rate per minute, subject to mutual agreement as to all the terms of
the agreement to provide such services, including, without limitation, the
volume commitment and duration.

               (b) With respect to services other than interexchange services,
when the Company or a Subsidiary does not itself develop, or is not permitted to
develop, one or more telecommunications services that are offered or provided in
connection with the conduct of its Business (including, by way of example, local
telephone services or voicemail), but instead procures such services, the
Company shall request in writing that AT&T PCS provide such services (directly
or through an Affiliate designated by it) and, provided, that AT&T PCS (or a
designated Affiliate) offers to provide such telecommunication services to the
Company on reasonably competitive terms, the Company or such Subsidiary shall
procure such services from AT&T PCS (or such Affiliate thereof).

          8.6  Exclusivity.

telecommunications services to or from specific locations (such as buildings or
office complexes), even if the subscriber equipment used in connection with such
service may be capable of routine movement within a limited area (such as a
building or office complex), and even if such subscriber equipment may be
capable of obtaining other telecommunications services beyond such limited area
(which other services may include routine movement beyond such limited area) and
handoff between the service to such specific locations and such other
telecommunications services; provided, however, that if AT&T PCS or any of its
Affiliates sells such mobile wireless subscriber equipment such equipment shall
be capable of providing (but not necessarily on an exclusive basis) Company
Communications Services and (iii) resell Company Communications Services
provided by a Person other than the Company in any geographical area within the
Territory in which the Company has not placed a Company System into commercial
service (it being understood that in the event that AT&T PCS or any of its
Affiliates that is reselling Company Communication Services of a Person other
than the Company in a geographic area within the Territory at the time the
Company places a portion of a Company System including such geographic area into
commercial service, AT&T PCS or its Affiliates, as applicable, shall terminate

days' prior notice of AT&T PCS' intention to engage in any resale activities
described in clause (iii) hereof to provide the Company with the opportunity to
discuss such proposed resale activities with AT&T PCS, such notice to include

Company System being placed into commercial operation in any such geographic
area within the Territory it will transfer all of its subscribers in such
geographic area to the Company System either directly to the Company or on the
terms and subject to the conditions contained in the Resale Agreement.  In
connection with any such transfer, AT&T PCS will use its best efforts to
facilitate such transfer, including cooperating with the Company regarding the
form(s) of notice to be sent to such subscribers informing them of such
transfer.  To the extent the "other telecommunications services" referred to in
clause (ii) of the first sentence of this Section 8.6(a) constitute Company
                                          --------------

or resell, or act as agent for any Person offering, such "other
telecommunications services" except in accordance with the terms of clause (i)
of the first sentence of this Section 8.6(a).  Nothing herein shall be construed
                              --------------

by AT&T PCS or its Affiliates or any Cash Equity Investor or any of its
Affiliates.

authorized dealers to its customers, at the time it is provided to such
customers, (to the extent such programming is technologically feasible) so that
the Company or AT&T PCS, as the case may be, and such Affiliates, in its and
such Affiliates' capacity as Serving Carrier, is the preferred provider of
service in the markets listed on such Schedules 1 and 2, and (ii) refrain, and
direct its authorized dealers to refrain, from inducing any of its customers to
change or, except at such customer's request in the event the quality of the
Company's services do not meet industry standards, changing the programming
described in clause (i) above. For the purpose of this Section 8.6(b), the terms
                                                       --------------

ascribed thereto in the Roaming Agreement.

interest in other business ventures, and may engage in any other activities, of
every kind and description (whether or not competitive with the business of the
Company or otherwise affecting the Company), independently or with others and
shall owe no duty or liability to the Company, the other Stockholders or their
Affiliates in connection therewith.  None of the Company or the other
Stockholders shall have any rights in or to such independent ventures or the
income or profits therefrom by virtue of this Agreement or any of the Related
Agreements.  Without limiting the generality of the foregoing, in the event that
AT&T PCS or a Cash Equity Investor or a Person affiliated with AT&T PCS or a
Cash Equity Investor develops inventions which are patentable or are otherwise
trade secrets relevant to the Business, AT&T PCS or such Cash Equity Investor or
affiliated Person shall nevertheless retain ownership of such invention and may
license it to the Company if the Company so desires and if mutually satisfactory
terms are agreed to.  The Company shall also have the right to develop any
inventions related to the Business deemed desirable by it and to retain title to
such inventions.  To the extent that, at law or in equity, AT&T PCS or a Cash
Equity Investor or any Person affiliated with AT&T PCS or a Cash Equity Investor
would have duties (including fiduciary duties) and liabilities to the Company,
or to the Stockholders, different from or in addition to those provided in this
Section 8.7 and Section 8.6 with respect to the subject matter of such Sections,
- -----------     -----------
all rights of the Company and the Stockholders arising out of such duties and
liabilities are hereby waived and no such Person shall be liable to the Company

          8.8  Acknowledgments and Termination of Exclusivity.
               ----------------------------------------------

               (a) The Stockholders hereby expressly acknowledge that none of
the Stockholders would have been willing to enter into this Agreement or make
contributions to the capital of the Company, except for each other Stockholder's
and its Affiliates willingness to enter into this Agreement (including without
limitation the provisions set forth in this Section 8) and the Related

            (b) Without limiting the foregoing, and without limiting the
remedies that may be available to it at law or in equity, in the event of a
Substantial Company Breach, the obligations of AT&T PCS and its Affiliates under
Section 8.6 shall automatically terminate and be of no further force or effect.
- -----------

            (c) Upon consummation of a Disqualifying Transaction, AT&T PCS may,
by notice to the Company, terminate its and its Affiliates' obligations under
Section 8.6 with respect to any Overlap Territory, provided that the obligations
- -----------
of AT&T PCS and its Affiliates pursuant to Section 8.6(b)(ii) shall continue in
                                           ------------------
effect with respect to the then existing customers of the PCS Systems and
Cellular Systems owned and operated by AT&T PCS and its Affiliates (and their
respective successors pursuant to the applicable Disqualifying Transaction)
before giving effect to such Disqualifying Transaction, so long as such
customers remain customers of such systems and such systems continue to be owned
or operated by AT&T PCS or its Affiliates.  Notwithstanding the foregoing, in
the event that the Company exercises its right pursuant to Section 6.1 to
                                                           -----------

          8.9  Equipment, Discounts and Roaming.  AT&T PCS acknowledges and
               --------------------------------
agrees that, subject to the terms of Sections 8.1 and 8.5, the Company shall

have the sole discretion to select (a) the equipment vendor(s) for the
infrastructure to be constructed by the Company and (b) billing and other
vendors providing goods and services to the Company.  If reasonably requested by
the Company, AT&T PCS agrees to use all commercially reasonable efforts to
assist representatives of the Company in obtaining discounts from any AT&T PCS
vendor with whom the Company is negotiating for the purchase of any such
subscriber or infrastructure equipment or billing services.  In addition, AT&T
PCS agrees to use all commercially reasonable efforts to enable the Company to
become a party to the roaming agreements between AT&T PCS and its Affiliates and
operators of other Cellular Systems and PCS Systems or, subject to the Company
agreeing to the obligations thereunder, entitled to the rights and benefits of
AT&T PCS under such roaming agreements.  The two immediately preceding sentences
shall not be construed to require AT&T PCS or its Affiliates to take any action
that AT&T PCS or such Affiliate determines in its sole discretion to be adverse
to its interests.

          8.10 ANS Agreement.  At the request of the Company, AT&T PCS shall
               -------------
cause AWS to enter into an Advanced Network Services Agreement with the Company,

          8.11 Resale Agreements.
               -----------------

            (a) From time to time, upon the request of AT&T PCS, the Company
shall enter into a Resale Agreement relating to the Territory, with AT&T PCS and
any of its Affiliates and, with respect to any geographic area within the
Territory, one other Person

                                       51
<PAGE>

designated by AT&T PCS, provided such other Person is licensed to provide
telecommunications services in such geographic area under the service marks used
by AT&T Corp. and such other Person qualifies as a reseller under any generally
applicable standards the Company establishes for its resellers from time to time
and upon the request of AT&T PCS, the Company shall enter into an agency
agreement authorizing AT&T PCS and any of its Affiliates and, with respect to
any geographic area within the Territory, one other Person designated by AT&T
PCS, provided such other Person is licensed to provide telecommunications
services in such geographic area under the service marks used by AT&T Corp. and
such other Person qualifies as an agent under any generally applicable standards
the Company establishes for its agents from time to time. Any such agency
agreements shall provide that the Company shall pay the agent a commission at
the rate then generally offered to the Company's agents and shall otherwise be
on commercially reasonable terms. At no time shall there be more than one Person
(other than AT&T PCS and its Affiliates) designated by AT&T PCS as a reseller or
an agent with respect to any geographic area within the Territory.

            (b) It is the intention of the parties that, in light of AT&T PCS's
equity interest in the Company and the other arrangements between AT&T PCS and
its Affiliates and the Company (including the roaming revenues anticipated to be
earned by the Company from subscribers of AT&T PCS and its Affiliates), the
rates, terms and conditions of Service (as defined in the Resale Agreement)
provided by the Company pursuant to the Resale Agreement or any other agreement
between AT&T PCS or such other reseller and the Company shall be at least as
favorable to AT&T PCS or such other reseller, taken as a whole, as the rates,
terms and conditions of Service, taken as a whole, provided by the Company to
any other Customer (as defined in the Resale Agreement) and, to the extent
permitted by applicable law, such rates, terms and conditions shall be superior
to those provided to any other Customer.  Without limiting the foregoing, the
rate plans offered by the Company pursuant to any Resale Agreement shall be
designed to result in the average actual rate per minute paid by the Reseller
for Service being at least 25% below the weighted average actual rate per minute
billed by the Company to its subscribers for access and air time, but excluding
revenues for features, taxes, toll or other non-rate items.  The Company and
Reseller shall negotiate commercially reasonable reductions to such resale rate
based upon increased volume commitments (including roaming charges incurred by
subscribers of AT&T PCS and its Affiliates).

engaging in a general solicitation for employment that is not directed at
employees of the Company.

            (c) Notwithstanding anything contained herein to the contrary, in
the event the Cash Equity Investors shall Beneficially Own less than (i) one
half but more than one quarter of the number of shares of Common Stock
Beneficially Owned by the Cash Equity Investors on February 4, 1998, the number
of directors the Cash Equity Investors shall be permitted to designate under
Section 3.1(a) shall be reduced to one, and (ii) one-quarter of the number of
- --------------
shares of Common Stock Beneficially Owned by the Cash Equity Investors on

the number of directors the Cash Equity Investors are entitled to designate is
reduced pursuant to Section 12.3(c)(i), one of the directors designated by the

or Stockholders shall remove them from the Board of Directors) and the remaining
directors shall take such action so that the number of directors constituting
the entire Board of Directors shall be reduced accordingly. In the event the
provisions of Section 3.1(a) are terminated pursuant to Section 12.3(c)(ii), the
              --------------                            -------------------

termination of this Agreement, or which may arise by an event causing the

          12.5 Waiver.  No failure or delay on the part of any Stockholder in
               ------
exercising any right, power or privilege hereunder, nor any course of dealing
between the Company and any Stockholder shall operate as a waiver thereof nor
shall any single or partial exercise of any right, power or privilege hereunder
preclude the simultaneous or later exercise of any other right, power or
privilege.  The rights and remedies herein expressly provided are cumulative and
not exclusive of any rights and remedies which any Stockholder would otherwise
have.  No notice to or demand on the Company in any case shall entitle the
Company to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Stockholders or any of
them to take any other or further action in any circumstances without notice or
demand.

          12.6 Obligations Several.  The obligations of each Stockholder under
               -------------------

in accordance with the law of the State of Delaware.

          12.8 Dispute Resolution.
               ------------------

          (a) The parties shall use and strictly adhere to the following dispute
resolution processes, except as otherwise expressly provided in this Section
                                                                     -------
12.8, to resolve any and all disputes, controversies or claims, whether based on
- ----
contract, tort, statute, fraud, misrepresentation or any other legal or
equitable theory (hereinafter, "Dispute(s)"), arising out of or relating to this
                                ----------
Agreement (and any prior agreement this Agreement supersedes), including without
limitation, its making, termination, non-renewal, its alleged breach and the
subject matter of this Agreement (e.g., products or services furnished hereunder
or those related to those furnished):

          (b) The parties shall first attempt to settle each Dispute through
good faith negotiations.  The aggrieved party shall initiate such negotiations
by giving the other party(ies) written notice of the existence and nature of the
Dispute.  The other party(ies) shall in a writing to the aggrieved party
acknowledge such notice of Dispute within ten (10) business days. Such
acknowledgment may also set forth any Dispute that the acknowledging party
desires to have resolved in accordance with this Section.

          (c) Thereafter, if any Dispute is not resolved by the parties through
negotiation within thirty (30) calendar days of the date of the notice of
acknowledgment, either party may terminate informal negotiations with respect to
that Dispute and request that the Dispute be submitted to non-binding mediation.
Any mediation of a Dispute under this Section shall be conducted by the CPR
Institute for Dispute Resolution ("CPR") in accordance with the then current CPR
                                   ---
"Model Mediation Procedure for Business Disputes" ("Model Procedures") and the
                                                    ----------------
procedures specified in this Section to the extent that they conflict with,
modify or add to such Model Procedures.  Any demand for initiation of mediation
of a Dispute must be given in writing to both the other party(is) involved and
to the CPR and must set forth the nature of the Dispute.  Each party to the
mediation shall bear its own expenses with respect to mediation and the parties
shall share equally the fees and expenses of the CPR and the mediator.  The
failure by a party to timely pay its share of the mediation fees and expenses of
the CPR and the mediator shall be a bar to arbitration under Section 12.8(d) of
                                                             ---------------
that party's Dispute(s).  Any mediation under this Section shall be conducted
within the State of New York at a site selected by the mediator that is
reasonably convenient to the parties.  Each party shall be represented in the
mediation by representatives having final settlement authority with respect to
the Dispute(s).  All information and documents disclosed in mediation by any
party shall remain private and confidential to the disclosing party and may not
be disclosed by any party outside the mediation. No privilege or right with
respect to any information or document disclosed in mediation shall be waived or
lost by such disclosure.

                                       59
<PAGE>

          (d) Any Dispute not finally resolved after negotiation and mediation
in accordance with Section 12.8(b) and 12.8(c) shall, upon the written demand of
                   ---------------------------
any involved party delivered to the other party(is) and the CPR, be finally
resolved through binding arbitration in accordance with the then current CPR
"Non-Administered Arbitration Rules" ("Arbitration Rules") and the procedures
                                       -----------------
specified in this Section to the extent that they conflict with, modify or add
to such Arbitration Rules.  Any Dispute of any other party not finally resolved
after negotiation and mediation pursuant to this Section may be made a part of
the arbitration demanded by another party, provided that the written notice of
demand for arbitration of that Dispute is received by the CPR before selection
of an arbitrator by the CPR.  Any demand for arbitration of a Dispute received
by the CPR after the selection of the arbitrator must be resolved through a
separate arbitration proceeding in accordance with this Section.  Each party
shall bear its own expenses with respect to arbitration and the parties shall
share equally the fees and expenses of the CPR and the arbitrator.  Unless
otherwise mutually agreed by the parties in writing, the arbitration shall be
conducted by one (1) neutral arbitrator.  The arbitration shall be conducted in
the State of New York at a site selected by the arbitrator that is reasonably
convenient to the parties.  The arbitrator shall be bound by and strictly
enforce the terms of the Agreement and may not limit, expand, or otherwise
modify the terms of this Agreement.  The arbitrator shall make a good faith
effort to apply applicable law, but an arbitration decision and award shall not
be subject to review because of errors of law.  The arbitrator shall have the
sole authority to resolve issues of the arbitrability of any Dispute, including
the applicability or running of any statute of limitation.  The arbitrator shall
not have power to award damages in connection with any Dispute in excess of
actual compensatory damages or to award punitive damages and each party
irrevocably waives any claim thereto.  The arbitrator shall not have the power
to order pre-hearing discovery of documents or the taking of depositions.  The
arbitrator may compel, to the extent provided by the FAA (as hereinafter
defined), attendance of witnesses and the production of documents at the
hearing.  The arbitrator's decision and award shall be made and delivered to the
parties within six (6) months of selection of the arbitrator by the CPR and
judgment on the award by the arbitrator may be entered by any court having
jurisdiction thereof.

          (e) This Section shall be interpreted, governed by and enforced in
accordance with the United States Arbitration Act, 9 U.S.C.  Sections 114 (the

"Federal Arbitration Act" or "FAA").  The laws of the State of New York, except
- ------------------------      ---
those pertaining to choice of law, arbitration of disputes and those pertaining
to the time limits for bringing an action that conflict with the terms of this
Dispute Resolution provision, shall govern all other substantive matters
pertaining to the interpretation and enforcement of the other terms of this
Agreement with respect to any Dispute.  Any party to a Dispute, which is the
subject of a notice initiating the Dispute resolution procedures under this
Section, may seek a temporary injunction in any state or federal court of
competent jurisdiction to the limited extent necessary to preserve the status
quo during the pendency of final resolution of a Dispute in accordance with this
Section.  If court proceedings to stay litigation of a Dispute or compel
arbitration of a Dispute are necessary, the party who unsuccessfully opposes
such proceedings shall pay all associated costs, expenses, and attorneys' fees
that the other party reasonably incurs in connection with such court

                                       60
<PAGE>

proceedings.  An order to pay such costs, expenses and attorney fees shall
become part of any decision and award of the arbitrator of the Dispute.  An
arbitrator appointed pursuant to Section 12.8(d) to resolve a Dispute may also
                                ----------------
issue such injunctive orders and shall have the power to modify or dissolve the
injunctive order of any court to the extent it pertains to the Dispute which the
arbitrator has been selected to finally resolve.  The parties, their
representatives, other participants, and the mediator and arbitrator shall hold
the existence, content, and result of the mediation and arbitration of a Dispute
in confidence except to the limited extent necessary to enforce a final
settlement agreement or to obtain and secure enforcement of or a judgment on an
arbitration decision and award.

          (f) The statute(s) of limitation applicable to any Dispute shall be
tolled upon initiation of the Dispute resolution procedures under this Section
and shall remain tolled until the Dispute is resolved by mediation or
arbitration under this Section.  Tolling shall cease if the aggrieved party with
a Dispute does not initiate mediation within sixty (60) calendar days after good
faith negotiations are terminated by any party and, after mediation of a
Dispute, if the aggrieved party with a Dispute does not initiate a demand for
arbitration within sixty (60) calendar days after mediation is terminated.
However, any Dispute is forever barred that has not expressly been made the
subject of the written notice required under Section 12.8(b) above within 365
                                             ---------------
days after the date the Party asserting the Dispute first knows or should have
known of the existence of the acts or omissions that give rise to such Dispute.

          (g) Unless the parties mutually agree in writing, Disputes relating to
trademarks (including service marks), patents and copyrights shall not be
resolved in accordance with the Dispute resolution procedures set forth in this
Section and shall be resolved as otherwise provided in this Agreement.

          (h) The Company and each of the Stockholders hereby irrevocably
consents to the exclusive jurisdiction of the state or federal courts in the
State of New York, and all state or federal courts competent to hear appeals
therefrom, over any actions which may be commenced against any of them under or
in connection with this Agreement.  The Company and each Stockholder hereby
irrevocably waive, to the fullest extent permitted by applicable law, any
objection which any of them may now or hereafter have to the laying of venue of
any such dispute brought in such court or any defense of inconvenient forum for
the maintenance of such dispute in the Southern District of New York and New
York County.  The Company and each Stockholder hereby agree that a judgment in
any such dispute may be enforced in other jurisdictions by suit on the judgment
or in any other manner provided by law.  The Company and each Stockholder hereby
consent to process being served by any party to this Agreement in any actions by
the transmittal of a copy thereof in accordance with the provisions of Section
                                                                       -------

          12.9  Benefit and Binding Effect; Severability.  This Agreement shall
                ----------------------------------------
be binding upon and shall inure to the benefit of the Company, its successors
and assigns, and each of the Stockholders and their respective executors,
administrators and personal representatives and heirs and permitted assigns.  If
any term or other provision of this Agreement is invalid,

                                       61

illegal or incapable of being enforced by any law or public policy or any
listing requirement applicable to the Common Stock, all other terms and
provisions of this Agreement shall nevertheless remain in full force and effect.
Upon such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto affected by such determination
in any material respect shall negotiate in good faith to modify this Agreement
so as to effect the original intent of the parties as closely as possible in an
acceptable manner in order that the provisions hereof are given effect as
originally contemplated to the greatest extent possible.

         12.10 Amendment of Bylaws.  The Stockholders agree that the terms of
               -------------------
this Agreement shall supersede any inconsistent provision that is contained in
the Restated Bylaws and, to the extent required by Delaware law or the Restated
Bylaws, this Agreement shall be deemed to constitute a written action taken by
the Stockholders of the Company and shall be deemed an amendment of the Restated
Bylaws.

         12.11 Authorized Agent of AT&T PCS.  AT&T PCS hereby authorizes
               ----------------------------
Wireless PCS, Inc.  as its agent, with full power to execute, in the name of and

PCS from complying with its obligations under this Agreement or any of the
Related Agreements to which it is a party.
