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, to 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 Offerees 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
- --------  -------
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; 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

                                      25


Offered Shares shall be closed on the first business day after all such consents
shall have been obtained by Final Order.

               (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.

               (e) The provisions of this Section 4.2 shall not be applicable to
the repurchase by the Company of any shares of Class A Voting Common Stock or
Class E Preferred Stock repurchased by the Company from an employee of the
Company in connection with such individual's termination of employment.

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

          (a)  No Stockholder shall, directly or indirectly, Transfer, in any
single transaction or series of related transactions to one or more Persons who
are not Affiliated Successors of such Stockholder (each such Person an
"Inclusion Event Purchaser") shares of any series or class of Company 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 any such class of Inclusion Stock (for purposes of this
Section 4.3, in the event that the Inclusion Stock is Series C Preferred Stock,
Series D Preferred Stock shall also be deemed to be Inclusion Stock and the
Series C Preferred Stock and Series D Preferred Stock shall be deemed to be one
class of Preferred Stock for purposes of this Section 4.3) 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

                                      26


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 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 Offerees, 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 Offerees. 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 Offerees
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 Offerees. Such process shall be
repeated in series until all of the remaining Inclusion Event Offerees 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

                                      27


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 Offerees shall be required, as a condition of participating
in such transaction, to convert its Preferred 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 Offerees 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 Offerees, it being understood that the directors selected
pursuant to Sections 3.1(e)(ii) and 3.11(a)(ii) shall be deemed independent for
such purposes.

          (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 clause (y) of Section 4.1(b)(iii), 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, AT&T PCS shall have the
exclusive right to negotiate with such Stockholder with respect to the purchase
of such shares; it being understood and agreed that such exclusive right shall
not be deemed to be a right of first offer or right of first refusal for the
benefit of AT&T PCS and such Stockholder shall have the right to reject any
offer made by AT&T PCS during such applicable first negotiation period. Upon the
expiration of such applicable first negotiation period, such Stockholder shall
have the right (for

                                      28


the applicable offer period hereinafter set forth with respect to each
applicable first negotiation period), following the expiration of such
applicable first negotiation period, to offer and sell such shares included in
such written notice on such terms and conditions as shall be acceptable to such
Stockholder in its sole discretion. If any of such shares included in such
written notice are not sold pursuant to the provisions of this Section 4.4 prior
to the expiration of the applicable offer period, such shares shall become
subject once again to the provision and restrictions hereof.

     If a Stockholder desires to Transfer shares of Common Stock (a) pursuant to
a Registration of Common Stock under Section 5 in an underwritten offering that
constitutes a bona fide distribution of such Common Stock pursuant to such
Registration, the applicable first negotiation period shall be ten (10) days and
the applicable offer period upon the expiration of such first negotiation period
shall be one hundred twenty (120) days, (b) pursuant to Rule 144, the applicable
first negotiation period shall be three (3) hours (it being understood and
agreed that such Stockholder shall, in addition to giving written notice of such
proposed Transfer by facsimile, use commercially reasonable efforts to contact
AT&T PCS by telephone in accordance with Section 12.1) and the applicable offer
period upon the expiration of such first negotiation period shall be five (5)
business days, and (c) in any single transaction or series of related
transactions to one or more Persons which will result in the Transfer by such
Stockholder (together with any other Stockholder participating in such single
transaction or series of related transactions) of not more than ten percent
(10%) of the Common Stock on a fully diluted basis (excluding for such purposes
the Series A Preferred Stock), the applicable first negotiation period shall be
one (1) business day, so long as notice of such proposed Transfer is given to
AT&T PCS prior to 9:00 A.M. on the day prior to the date of such proposed
Transfer (it being understood and agreed that such Stockholder shall, in
addition to giving written notice of such proposed Transfer by facsimile, use
commercially reasonable efforts to contact AT&T PCS by telephone in accordance
with Section 12.1) and the applicable offer period upon the expiration of such
first negotiation period shall be ten (10) business days.

     4.5  Additional Conditions to Permitted Transfers.
          --------------------------------------------

          (a) As a condition to any Transfer to an Affiliated Successor
permitted pursuant to Section 4.1, or any Transfer 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 without compliance with such
provisions of this Agreement shall be null and void and such transferee shall
have no rights as a Stockholder of the Company.

          (b) Notwithstanding anything to the contrary contained in this
Agreement, each Stockholder agrees that it will not effect a Transfer of shares
of Company Stock to a Prohibited Transferee; provided, however, that nothing
contained in this Section 4.5(b) shall be construed to prohibit a Transfer of
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

                                      29


the Common Stock outstanding if any Prohibited Transferee shall acquire,
directly or indirectly, in a private sale Beneficial Ownership of more than 33-
1/3% of any class of equity securities or equity interest in, such Stockholder.

          (c) Subject to Sections 4.1 and 4.2, prior to the IPO Date, the Cash
Equity Investors, AT&T PCS and TWR Cellular may not Transfer shares of Common
Stock to any Person that is not an Affiliated Successor of such Stockholder or
another Cash Equity Investor unless after giving effect to such Transfer each of
such Stockholder and such Person shall after giving effect to such Transfer
Beneficially Own more than the lesser of (x) five percent (5%) of the Common
Stock, and (y) one-half of the Common Stock Beneficially Owned by the transferor
on the date hereof, upon such Transfer unless the Transfer by such Cash Equity
Investor, AT&T PCS or TWR Cellular is a Transfer of all of the shares of Common
Stock, as applicable, Beneficially Owned by it. Subject to Sections 4.1 and 4.2,
prior to the IPO Date, no Management Stockholder may effect more than one (1)
Transfer of its shares of Common Stock to a Person that is not an Affiliated
Successor of such Management Stockholder during any twelve (12) month period.

     4.6  Representations and Warranties. A Stockholder purchasing shares of
          ------------------------------
Company Stock pursuant to Section 4.2 shall be entitled to receive
representations and warranties from the transferring Stockholder that such
Stockholder has the authority (corporate or otherwise) to sell such shares, is
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
Equity Investor may, execute an instrument in form satisfactory to the Company
agreeing to pay in full such Stockholder's Unfunded Commitment outstanding on
the date of such proposed Transfer, provided, however, that such Stockholder
                                    --------  -------
shall not be released from its obligation in respect of such Unfunded
Commitment. No Transfer of any shares of Preferred Stock and/or Common Stock
shall be made except in compliance with all applicable securities laws. Any
Transfer made in violation of this Agreement shall be null and void.

          (b) The Company agrees that it will not, without the prior written
consent of AT&T PCS, Transfer, issue or dispose of any Equity Securities to a
Prohibited Transferee except

                                      30


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) a Qualified Holder, and (B) Management
Stockholders that in the aggregate Beneficially Own at least 50.1% of the shares
of Class A Voting Common Stock then Beneficially 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 in the aggregate 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 Class A Voting 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 Class A Voting
Common Stock issuable upon such conversion under such Registration Statement.

                                      31


          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 (i) AT&T
PCS and/or (ii) Management Stockholders that in the aggregate Beneficially Own
at least 50.1% of the shares of Class A Voting 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 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 to 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
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 Class A Voting Common Stock (or securities convertible into or exchangeable
for

                                      32


 Class A Voting 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. 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
or supplements to the Registration Statement or the Prospectus or for additional
information; (C) of the issuance by the Commission of any stop order suspending

warranties of the Company contemplated by subsection (xiv) of this subsection
(d) below cease to be true and correct; (E) of the receipt by the Company

                                      34


of any notification with respect to the suspension of the qualification of the
Registrable Securities for sale under the securities or blue sky laws of any
jurisdiction or the initiation or threatening of any proceeding for such
purpose; and (F) of the happening of any event which makes any statement made in
the Registration Statement, the Prospectus or any document incorporated therein
by reference untrue or which requires the making of any changes in the
Registration Statement, the Prospectus or any document incorporated therein by
reference in order to make the statements therein not misleading;

          (iv)   use its reasonable best efforts to obtain the withdrawal of any
order suspending the effectiveness of (I) the Registration Statement, or (II)
the qualification of the Registrable Securities for sale under the securities or
blue sky laws of any jurisdiction at the earliest possible time;

          (v)    if requested by the managing underwriter or underwriters or a
holder of Registrable Securities being sold in connection with an underwritten
offering, promptly incorporate in a Prospectus supplement or post-effective
amendment such information as the managing underwriters and the holders of a

number of Registrable Securities being sold to such underwriters, the purchase
price being paid therefor by such underwriters and any other terms of the
underwritten (or best efforts underwritten) offering of the Registrable
Securities to be sold in such offering; and make all required filings of such
Prospectus supplement or post-effective amendment as soon as notified of the
matters to be incorporated in such Prospectus supplement or post-effective
amendment;

as such selling holder of Registrable Securities underwriters may reasonably
request in order to facilitate the public sale or other disposition of the
securities owned by such selling holder;

          (viii) prior to any public offering of Registrable Securities, use its
reasonable best efforts to register or qualify or cooperate with the selling
holders of Registrable Securities, the underwriters, if any, and their
respective counsel in connection with the Registration or qualification of such
Registrable Securities for offer and sale under the securities or "blue sky"
laws of such jurisdictions in the United States as any seller or underwriter
reasonably requests in writing, use its reasonable best efforts to obtain all
appropriate registrations, permits and consents required in connection
therewith, and do any and all other acts or things reasonably necessary or
advisable to enable the disposition in such jurisdictions of

                                      35


the Registrable Securities covered by the Registration Statement; provided,
                                                                  --------
however, that the Company will not be required to qualify generally to do
- -------
business in any jurisdiction where it is not then so qualified or to take any
action that would subject it to taxation or general service of process in any
such jurisdiction where it is not then so subject;

               (ix)   cooperate with the selling holders of Registrable
Securities and the managing underwriters, if any, to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold and not bearing any restrictive legends and to be in such denominations
and registered in such names as the managing underwriters may request at least
two (2) business days prior to any sale of Registrable Securities to the
underwriters;

               (x)    use its reasonable best efforts to cooperate with any
selling holder to cause the Registrable Securities covered by the applicable
Registration Statement to be registered with or approved by such other
governmental agencies or authorities in the United States as may be necessary to
enable the seller or sellers thereof or the underwriters, if any, to consummate
the disposition of such Registrable Securities;

               (xi)   upon the occurrence of any event contemplated by
subsection (iii)(F) above, promptly prepare a supplement or post-effective
amendment to the Registration Statement or the related Prospectus or any
document incorporated therein by reference or file any other required document
so that, as thereafter delivered to the purchasers of the Registrable
Securities, the Prospectus will not contain an untrue statement of a material
fact or omit to state any material fact necessary to make the statements therein
not misleading;

               (xii)  cause all Registrable Securities covered by any
Registration Statement to be listed on each securities exchange on which similar
securities issued by the Company are then listed, or, if not so listed, cause
such Registrable Securities to be authorized for trading on the NASDAQ National
Market System if any similar securities issued by the Company are then so
authorized, if requested by the holders of a majority of such Registrable
Securities or the managing underwriters, if any;

               (xiii) not later than the effective date of the applicable
Registration, provide a CUSIP number for all Registrable Securities;

               (xiv)  enter into such customary agreements (including in the
case of a Demand Registration that is an underwritten offering, an underwriting
agreement in customary form) and take all such other actions reasonably required
in connection therewith in order to expedite or facilitate the disposition of
such Registrable Securities and in such connection, whether or not an
underwriting agreement is entered into and whether or not the Registration is an
underwritten Registration, (A) make such representations and warranties to the
holders of such Registrable Securities and the underwriters, if any, in form,
substance and scope as are customarily made by issuers to underwriters in
primary underwritten offerings; (B) use reasonable best efforts to obtain
opinions of counsel to the Company and updates thereof (which opinions of
counsel shall be in form, scope and substance reasonably satisfactory to the

                                      36


managing underwriters, if any, and to the holders of a majority of the
Registrable Securities being sold), addressed to each selling holder and the
underwriters, if any, covering the matters customarily covered in opinions
requested in underwritten offerings and such other matters as may be reasonably
requested by such holders and underwriters; (C) use reasonable best efforts to
obtain "cold comfort" letters and updates thereof from the Company's independent
certified public accountants addressed to the selling holders of Registrable
Securities and the underwriters, if any, such letters to be in customary form
and covering matters of the type customarily covered in "cold comfort" letters
by underwriters in connection with primary underwritten 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

                                      37


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 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

                                      38


against any and all losses, claims, damages, expenses or liabilities (or actions
in respect thereof), joint or several, 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 the person

                                      39


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 "Indemnifying Party"),
give written notice to each such Indemnifying Party of the commencement of such
action or claim,

                                      40


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.

          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.

                                      41


          (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
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

     6.   Disqualifying Transactions.
          --------------------------

     6.1  Company Conversion Rights. In the event AT&T PCS terminates its
          -------------------------
obligations under Section 8.6 pursuant to Section 8.8(c) with respect to any
Overlap Territory, the Company shall have the following rights which may be
exercised by the Company in its sole discretion during the sixty (60) day period

denominator of which is the total number of POPS in the Territory, of the shares
of Series A Preferred Stock then owned by AT&T PCS, TWR Cellular and each
Section 4.12 Transferee for an equivalent number of shares of Series B Preferred
Stock determined in accordance with the Restated Certificate; and

and the denominator of which is the total number of POPs in the Territory, of
the shares of Series D Preferred Stock, Series F Preferred Stock and Common
Stock Beneficially Owned by AT&T PCS and TWR Cellular on the date hereof (or
shares of Common Stock or Senior Common Stock into which such shares of Series D
Preferred Stock, Series F Preferred Stock and Senior Common Stock shall have
been converted) and that AT&T PCS, TWR Cellular or a Section 4.12 Transferee
continues to own on the date such right is exercised by the Company for that
number of shares of Series B Preferred Stock as shall be equal to the aggregate
purchase price paid by AT&T PCS and TWR Cellular for all of such shares of
Series D Preferred Stock, Series F Preferred Stock and Common Stock that AT&T
PCS, TWR Cellular or such Section 4.12 Transferee then Beneficially Owns
(including any shares of Common Stock or Senior Common Stock into which such
Series D Preferred Stock, Series F Preferred Stock and Senior Common Stock shall
have been converted) divided by the liquidation preference of the Series B
Preferred Stock determined in accordance with the Restated Certificate;

provided, however, that (x) if the Company exercises its right under clause
- --------  -------
(i)(A) of this Section 6.1(a) it shall be required to exercise its right under
clause (ii)(A) of this Section 6.1(a), and vice versa; and if the Company
exercises its right under clause (i)(B) of the Section 6.1(a) it shall be
required to exercise its right under clause (ii)(B) of this Section 6.1(a) and
vice versa, and (y) the provisions of this Section 6.1(a) shall not apply to any
Section 4.12 Transferee which is a Cash Equity Investor.

          (b)  The Company may redeem the shares of Series B Preferred Stock at

     6.2  Joint Marketing Right. During the period commencing on the date of
          ---------------------
announcement by AT&T PCS of a transaction meeting the description of a
transaction set forth in clauses (a), (b) and (c) of the definition of a
Disqualifying Transaction (unless AT&T PCS notifies the Company it has waived
its right to declare such transaction a Disqualifying Transaction in which
event, this Section 6.2 shall not be applicable to such transaction) and
terminating on the later of (x) six (6) months after the date of consummation of
such transaction,

                                      44


and (y) if applicable, the date by which AT&T PCS is required under applicable
law to dispose of any PCS System or Cellular System serving a Subject Market
(the "Section 6.2 Period"), the following provisions shall apply:

          (a)  If AT&T PCS proposes to sell, transfer or assign to any Person
which is not an Affiliate of AT&T PCS any Subject Market, AT&T PCS shall give
written notice (the "Company Sale Notice") to the Company and the Company shall
have the right, exercisable by written notice given within ten (10) days of
receipt of the Company Sale Notice, to elect to cause AT&T PCS to offer for sale
jointly with the Company for a period of ninety (90) days the Subject Markets
covered by the Company Sale Notice together with all of the Territory included
in the MTA that includes the Subject Markets (the "Joint Marketing Period"). In
the event that AT&T PCS has granted similar rights to the rights set forth in
this Section 6.2 to any Permitted Merger Participant and any Subject Market is
also a "Subject Market" under the terms of any agreement between AT&T PCS and
any such Permitted Merger Participant, the Company agrees that any territory of
the Permitted Merger Participant that is required under the terms of such
agreement to be offered for sale jointly with any Subject Markets shall be
offered for sale jointly with such Subject Markets and all of the Territory
included in the MTA that includes such Subject Markets. During the Joint
Marketing Period, AT&T PCS shall not sell the Subject Markets other than in a
transaction that includes the Subject Markets and the Territory included in the
MTA that includes the Subject Markets, provided, however, that neither AT&T PCS
                                       --------  -------
nor the Company shall be obligated to enter into a transaction for such Subject
Markets and such Territory other than on terms acceptable to each of them in
their sole discretion. This Section 6.2 shall cease to apply to any Subject
Market upon the earlier of (x) if the Company fails to make the joint marketing
election with respect to the applicable Subject Market within the ten (10) day
period referred to above, the expiration of such ten (10) day period, or (y) if
the Company makes the joint marketing election with respect to the applicable
Subject Market, upon the expiration of the Joint Marketing Period.

          (b)  Nothing contained in this Section 6.2 shall (x) be construed to
require AT&T PCS to deliver a Company Sale Notice with respect to any Subject
Market except during the Section 6.2 Period, (y) extend the obligation of AT&T
PCS set forth in this Section 6.2 beyond the expiration of the Section 6.2
Period or (z) apply to any sale, transfer or assignment of any Subject Market
pursuant to an agreement executed on any date not within the Section 6.2 Period.

          (c)  Nothing in this Agreement shall be construed to require AT&T PCS
to deliver the notice described in clause (d) of the definition of a
Disqualifying Transaction, including, without limitation, circumstances in which
AT&T PCS or its Affiliates enters into any transaction meeting the description
of a transaction set forth in clauses (a), (b) and (c) of the definition of a
Disqualifying Transaction.

                                      45


     7.   Additional Rights and Covenants.
          -------------------------------

     7.1  Financial Statements. The Company shall provide to each Stockholder
          --------------------
(a) within seventy-five (75) days after the end of each fiscal quarter (other
than the fourth fiscal quarter) or such shorter periods as is required pursuant
to the terms of the Company's senior indebtedness, the unaudited consolidated
balance sheet of the Company and its Subsidiaries as at the end of such period
and the related unaudited consolidated statements of income, surplus and cash
flows for such period and year-to-date and (b) within one hundred twenty (120)
days after the end of each fiscal year, the audited consolidated balance sheet
of the Company and its Subsidiaries as at the end of such year and the related
unaudited consolidated statements of income, surplus and cash flows for such
year. All financial statements and information provided pursuant to this Section
7.1 shall constitute Confidential Information under Section 7.7.

     7.2  Purchase Right.
          --------------

          (a)  If on or prior to the IPO Date the Company proposes to offer,
issue, sell or otherwise dispose of shares of any class or series of common
stock or Preferred Stock, or options, rights, warrants, conversion rights or
appreciation rights relating thereto, or any other type of equity security
(collectively, "Equity Securities") of the Company for cash to any Person,
including pursuant to an initial public offering, (x) the Company shall, prior
to any such offer, issuance, sale or other disposition, give written notice (an
"Issuance Notice") to each of the Stockholders setting forth the purchase price
of such Equity Securities (or, in the case of an initial public offering, the
anticipated price range), the type and aggregate number of Equity Securities or
rights to acquire Equity Securities to be so offered, issued, sold or otherwise
disposed of, the terms and conditions of such offer, issuance, sale or other
disposition, and the rights, powers and duties inhering in such additional
Equity Securities or rights to acquire Equity Securities, and (y) each
Stockholder shall have the right (the "Purchase Right") to acquire the
percentage of Equity Securities proposed to be offered, issued, sold or
otherwise disposed of equal to the number of shares of Class A Voting Common
Stock then Beneficially Owned by such Stockholder divided by the aggregate
number of shares of Class A Voting Common Stock outstanding immediately prior to
such offer, issuance, sale or other disposition of Equity Securities (including
any shares of Class A Voting Common Stock Beneficially Owned by such
Stockholder); provided, however, that the terms and conditions of this Section
              -------- --------
7.2 shall not apply to any offer, issuance, sale or other disposition of Equity
Securities or rights to acquire Equity Securities to any Person pursuant to a
stock option or stock appreciation rights plan established by the Company for
the benefit of its employees, officers, directors, agents or consultants, or
otherwise granted to an employee of the Company in connection with such person's
employment by the Company. In the case of an offer, issuance sale or other
disposition of Equity Securities issued as part of a unit with other debt,
equity or other securities of the Company, the right of a Stockholder to acquire
such Equity Security shall be conditioned upon such Stockholder's acquisition of
such debt, equity or other securities included in such unit.

          (b)  Each Stockholder may exercise such Purchase Right, in whole or in
part, on the terms and conditions and for the purchase price set forth in the
Issuance Notice, by giving

                                      46


to the Company notice to such effect, within thirty (30) days after the giving
of the Issuance Notice. In the case of an initial public offering, the following
conditions shall apply to the Purchase Right set forth herein: (i) In the event
that a Stockholder exercises such Purchase Right, such Stockholder shall be
obligated to exercise such right if the public offering price is not greater
than the highest price in the anticipated range specified in the applicable
notice, and (ii) in the event that a Stockholder exercises such Purchase Right
and the public offering price is greater than the highest price in the
anticipated range specified in the applicable notice, such Stockholder shall
have the right but not the obligation, to exercise such right at such public
offering price. After the expiration of such thirty (30) day period, the Company
shall have the right to offer, issue, sell and otherwise dispose of any or all
of the Equity Securities referred to in the applicable Issuance Notice as to
which no Purchase Right has been exercised but only upon the terms and
conditions, and for a purchase price not lower than the purchase price set forth
in the Issuance Notice; provided, however, that in the case of an initial public
offering, such right of the Company shall be the right to offer, issue, sell and
otherwise dispose of such Equity Securities at any price. In the event of an
initial public offering of Equity Securities at a price more than 20% below such
lowest price, AT&T PCS shall have the right, exercisable at the time of pricing
of such initial public offering, to exercise such Purchase Right. If the Company
does not offer, issue, sell or otherwise dispose of the Equity Securities
referred to in the applicable Issuance Notice on the terms and conditions set
forth in such Issuance Notice within one hundred twenty (120) days after the
expiration of such thirty (30) day period, then any subsequent proposal by the
Company to offer, issue, sell or otherwise dispose of such Equity Securities
shall be subject to this Section 7.2.

     7.3  Access. The Company shall permit, and shall cause each of its
          ------
Subsidiaries to permit, upon reasonable notice, during normal business hours,
each Qualified Holder and its directors, officers, employees, attorneys,
accountants, representatives, consultants and other agents, at the sole expense
of such Qualified Holder, to (a) visit and inspect any of the properties and
facilities of the Company and its Subsidiaries, (b) examine and make copies of
and extracts from the corporate and financial records of the Company and its
Subsidiaries, (c) discuss the affairs, finances and accounts of the Company or
any such Subsidiary with any of its officers, directors and key employees and
its independent accountants, and (d) otherwise investigate the properties,
businesses and operations of the Company and its Subsidiaries, in each case as
such Qualified Holder reasonably deems necessary; provided, however, that each
                                                  --------  -------
Qualified Holder may exercise its rights pursuant to this Section 7.3 no more
than three times in any 12 month period. The Company shall, and shall cause each
of its Subsidiaries and the officers, directors and employees of the Company and
its Subsidiaries to, cooperate fully in connection with such inspection,
examinations and discussions. The presentation of a copy of this Agreement by
any Qualified Holder to the independent accountants of the Company or any of its
Subsidiaries shall constitute permission by the Company or such Subsidiary to
its independent accountants to participate in discussions with such Qualified
Holder.

     7.4  Merger, Sale or Liquidation of the Company.
          ------------------------------------------

                                      47


          (a)  Except for transactions permitted pursuant to Section 7.11 and to
the extent permitted in this Section 7.4, the Company shall not, and shall not
permit any of its Subsidiaries to, except with the prior written consent of AT&T
PCS or in accordance with Sections 7.4(b) and 7.4(c), effect (i) any merger,
combination 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 winding up of the Company or such
Subsidiary.

          (b)  The Company and its Subsidiaries may effect a Company Merger,
without the prior written consent of AT&T PCS, (i) in which the only constituent
corporations are two or more of the Company's wholly owned Subsidiaries, (ii) in
which the only constituent corporations are the Company and one or more of its
wholly owned Subsidiaries and the Company is the surviving corporation, or (iii)
between a Subsidiary of the Company and another entity for the purpose of
acquiring such other entity; provided, that (x) such transaction does not affect
                             --------
the capital structure of the Company, except to the extent the Company issues
common stock to the stockholders of the other entity pursuant to the terms of
such Company Merger, (y) the surviving corporation is a direct or indirect
wholly owned Subsidiary of the Company, and (z) the consummation of such
transaction does not violate Section 8.1(a).

          (c)  The Company and its Subsidiaries may effect any of the
transactions described in clauses (i) or (ii) of Section 7.4(a) (a "Sale
Transaction"), without the prior written consent of AT&T PCS, if (a) such
transaction has no material effect on AT&T PCS' equity interest in the Company
(and the seniority thereof) or its rights under this Agreement, (b) the
Company's direct or indirect interest in its assets is unaffected by such
transaction in any material respect, and (c) such transaction is otherwise
equivalent in all material respects to AT&T PCS to the sale by each of the other
Stockholders of its equity interests in the Company for cash or marketable
securities; provided, that any such Sale Transaction shall nevertheless be
            --------
subject to a right of first offer in accordance with the provisions of Section
7. 4(d).

          (d)  Prior to entering into a Sale Transaction, the Company shall give
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
Sale Notice shall constitute an irrevocable offer (a "Sale Offer") to enter into
the Sale Transaction with AT&T PCS on the terms set forth in the Sale Notice.
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 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

                                      48


(for a period of ninety (90) days following the expiration of the thirty (30)
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 shall be
          -------------------------
direct or indirect wholly owned Subsidiaries of the Company, and the Company
shall not, and shall not permit any Subsidiary to, sell or issue, 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.

     7.6  Amendments of the Restated Certificate and By-Laws. Prior to the IPO
          --------------------------------------------------
Date, the Company shall not, without the prior written consent of AT&T PCS,
authorize or adopt any amendment, modification or repeal of any provision of the
Restated Certificate or the Restated By-Laws, unless such amendment is
consistent with the terms of this Agreement.

     7.7  Confidentiality.
          ---------------

          (a)  Each party shall, and shall cause each of its Affiliates, and its
and their respective stockholders, members, managers, directors, officers,
employees and agents (collectively "Representatives") to, keep secret and retain
in strictest confidence any and all information relating to the Company or any
other party that is designated in writing by the party providing such
information or the Company as confidential ("Confidential Information") and
shall not disclose such information, and shall cause its Representatives not to
disclose such information, to anyone except such Affiliates, Representatives or
any other Person that agrees in writing to keep in confidence all such
information in accordance with the terms of this Section 7.7. Each party agrees
to use such information received from another party or the Company only in
connection with its ownership interest in the Company but not for any other
purpose. All such information furnished pursuant to this Agreement shall be
returned promptly to the party to whom it belongs upon request by such party.

          (b)  To the fullest extent permitted by law, if a party or any of its
Affiliates or Representatives breaches, or threatens to commit a breach of, this
Section 7.7, the party whose Confidential Information shall be disclosed, or
threatened to be disclosed, shall have the right and remedy to have this Section
7.7 specifically enforced by any court having jurisdiction, it being
acknowledged and agreed that money damages will not provide an adequate remedy
to such party. Nothing in this Section 7.7 shall be construed to limit the right
of any party to collect money damages in the event of breach of this Section
7.7.

                                      49


          (c)  Anything else in this Agreement notwithstanding, each party shall
have the right to disclose any information, including Confidential Information
of the other party or such other party's Affiliates, in any filing with any
regulatory agency, court or other authority or any disclosure to a trustee of
public debt of a party to the extent that the disclosing party determines in
good faith that it is required by Law, regulation or the terms of such debt to
do so; provided, 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.

     7.8  IPO Date. In the event that the IPO Date shall not have occurred on or
          --------
prior to the fifth (5th) anniversary of the date hereof, the Company shall, at
the request of any Qualified Holder, as promptly as is reasonably practicable
after the date of such request, undertake a registration of Common Stock
pursuant to an effective Registration Statement that results in the occurrence
of the IPO Date; provided, however, that if the Board of Directors determines
                 --------  -------
that such registration would interfere with any pending or contemplated material
acquisition, disposition, financing or other material transaction, the Company
may defer such registration (including by withdrawing any Registration Statement
filed in connection with such registration); provided that the aggregate of all
                                             --------
such deferrals shall not exceed one hundred twenty (120) days in any 360-day
period. Any such registration shall be pursuant to an underwritten offering.
Each Stockholder agrees to cooperate in such registration, including, without
limitation, entering into customary holdback agreements.

     7.9  AT&T PCS Retained Licenses. In the event that AT&T PCS desires to
          --------------------------
Transfer all or any of the AT&T PCS Retained Licenses in the Territory at any
time prior to the eighth anniversary of the date hereof, AT&T PCS shall give
written notice thereof to 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 desires to sell. For a period of thirty (30)
days after the date such notice is 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.

     7.10 Regulatory Cooperation. Each of the Stockholders severally agrees to
          ----------------------
comply with the last sentence of Section 6.7 of the Securities Purchase
Agreement.

     7.11 Permitted Transactions. Notwithstanding the terms of Section 7.4(a)
          ----------------------
and 8.4(a):

                                      50


          (a)  after completion of the Minimum Build-Out Plan and certification
that Company Systems meet the TDMA Quality Standards, the Company and its
Subsidiaries may effect a merger, combination of consolidation with or into a
Permitted Merger Participant or acquire all or substantially all of the assets
of a Permitted Merger Participant or sell all or substantially all of the assets
of the Company and its Subsidiaries to a Permitted Merger Participant (any such
transaction being referred to as a "Permitted Consolidation Transaction"), so
long as such transaction is approved by the Board of Directors and the holders
of the Company's capital stock to the extent such approval is required pursuant
to the Restated Certificate or applicable law;

          (b)  the Company may acquire FCC Licenses (each such License a
"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
or its assets. Notwithstanding the foregoing, the Company shall not acquire any
Permitted Cellular License if the acquisition of such License would adversely
affect the Company's ability to satisfy its obligations under the first sentence
of Section 8.1(b); and

          (c)  The Company may acquire licenses issued by the FCC to provide
wireless services (other than FCC Licenses) (each such license a "Permitted Non-
CMRS 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 Permitted Non-CMRS License (and any
other assets being acquired together therewith) is necessary or desirable to
constructing a PCS System in the applicable area within the PCS Territory,
provided that, (i) the POPs included in the geographic area covered by such
- --------
License are within the PCS Territory, (ii) none of AT&T PCS or any Affiliate
thereof owns an interest in a similar Permitted Non-CMRS License in such
geographic area, (iii) the ownership of such License will not conflict with, or
cause AT&T PCS or any Affiliate thereof to be in violation or breach of any
agreement, instrument, Law or License applicable to or binding upon such Person
or its assets, and (iv) the service to be provided by the Company using such
Permitted Non-CMRS License complies with the definition of Business.
Notwithstanding the foregoing, the Company shall not acquire any Permitted Non-
CMRS License if the acquisition of such License would adversely affect the
Company's ability to satisfy its obligations under the first sentence of Section
8.1(b).

     7.12 Springfield/Joplin. In the event that AT&T PCS shall propose to sell,
          ------------------
transfer or otherwise dispose of its interest in the Springfield/Joplin System
to any Person other than the Company, AT&T PCS agrees to negotiate in good faith
with the Company to sell the License for

                                      51


the Springfield/Joplin BTA to the Company; it being understood that AT&T PCS
shall have no obligation to sell such License to the Company unless the terms
thereof are satisfactory to AT&T PCS in its sole discretion. In the event the
Company does not acquire an FCC PCS License covering the Springfield/Joplin BTA,
the Minimum Build-Out Plan for the St. Louis MTA shall be deemed to be amended
to be the minimum build-out requirements under applicable FCC rules in lieu of
the build-out requirements set forth in the Minimum Build-Out Plan.

     7.13 Covenant of Holders of Class C Common Stock. (a) Each holder of
          -------------------------------------------
Class C Common Stock hereby covenants and agrees that, for so long as it is a
holder of any Class C Common Stock and for so long as required by FCC rules, it
will maintain its status as an "Institutional Investor", as such term is used in
47 CFR Section 24.720(h), and that it will give written notice to the Company
within five (5) days after such Stockholder becomes aware that it no longer
maintains such status for any reason (the "Transfer Event"). Upon the
                                           --------------
occurrence of a Transfer Event with respect to any Stockholder under
circumstances such that (i) the failure of the Stockholder to maintain its
status as an Institutional Investor would compromise any of the material
benefits the Company derives as a "Very Small Business", as defined in 47 CFR
(S) 24.720(b)(2) or from the Company's eligibility to bid on frequency block "C"
or "F" licenses, as specified in 47 CFR Section 24.709 or be eligible to receive
any of the rights specified in 47CFR Sections 27.711, 24.712, 24.716 and 24.717
(collectively, the "Material Benefits") and (ii) the Stockholder is unable to
                    -----------------
obtain a waiver from the FCC regarding, or to cure, such Transfer Event or loss
of Material Benefits, the other holders of Class C Common Stock at the time
shall have the right to purchase any or all of such Stockholder's Class C Common
Stock pursuant to the terms hereof, or, if not so purchased by the other holders
of Series C Common Stock, by one or more Persons designated by the Company.

          (b) Within fifteen (15) days of becoming aware that a Transfer Event
has occurred with respect to a Stockholder, the Company shall give the other
holders of Class C Common Stock notice of their right to purchase the
Stockholder's Class C Common Stock for the purchase price paid by such holder of
Class C Common Stock.

          (c)  Notwithstanding the foregoing, any Stockholder which suffers a
Transfer Event may, if to do so would avoid the loss of Material Benefits, elect
to convert all or part of its Class C Common Stock to another class of Common
Stock which the Company has authorized, or to waive in writing such rights
pertaining to its ownership of such stock as may be necessary to avoid the loss
of Material Benefits, which election shall be made no later than five (5) days
before the FCC Determination Date.

     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

                                      52


material respects with systems being used in a Majority of the Central and
Southwest Region (including without limitation for the purpose of facilitating
roaming and hand-off 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 Central and Southwest 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 24.203 with respect to the AT&T PCS Retained Licenses in the Territory and
the AT&T PCS 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
Licenses, as applicable.

          (c)  The Company will arrange for all necessary microwave relocation
in connection with the AT&T PCS 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 Central and Southwest 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 non-compliance 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

                                      53


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)  During the period commencing on the date hereof through and
including the first anniversary of the date hereof, without obtaining the prior
written consent of each SBIC Holder, the Company will not, and will not permit
any of its Subsidiaries, to conduct, directly or indirectly, any business other
than the Business.

          (c)  If at any time during the term of this Agreement AT&T PCS and its
Affiliates determine to discontinue use of TDMA in a Majority of the United
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) interchange services that
constitute Company Communication Services and (ii) interexchange services
procured from AT&T Corp. or an Affiliate thereof

                                      54


designated by AT&T Corp. Such interexchange services shall be provided by AT&T
Corp. or such Affiliate at the same rates as the rates charged by AT&T Corp. or
such Affiliate to other similarly situated carriers. It is anticipated that such
services will be provided by AT&T Corp. or such Affiliate pursuant to an
agreement incorporating such rates.

          (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.
          -----------

          (a)  None of the Stockholders or their respective Affiliates will
provide or resell, or act as the agent for any Person offering, within the
Territory, Company Communications Services except that, AT&T PCS and its
Affiliates may (i) resell, or act as the Company's agent for, Company
Communications Services provided by the Company in accordance with the Resale
Agreement (or any other agreement between AT&T PCS and its Affiliates, on the
one hand, and the Company, on the other hand), including bundling any such
Company Communications Services with other telecommunications services marketed,
offered and provided or resold by such Person, (ii) provide or resell wireless
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
hand-off 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
such resale arrangement with respect to such geographic areas within thirty (30)
days of the date such portion of a Company System is placed in commercial
service). AT&T PCS agrees to provide the Company with not less than sixty (60)
days' prior notice of any resale activities described in clause (iii) hereof,
such notice to include a reasonable description of such

                                      55


resale activities and to use tri-mode phones, to the extent commercially
reasonable in connection with such resale activities. To the extent the "other
telecommunications services" referred to in clause (ii) of the first sentence of
this Section 8.6(a) constitute Company Communications Services, neither AT&T PCS
nor any of its Affiliates or any AT&T Licensee may provide or resell, or act as
agent for any Person offering, such "other telecommunications services" except
Company Communications Services provided by the Company in accordance with the
terms of clause (i) of the first sentence of this Section 8.6(a). Nothing herein
shall be construed to limit in any respect any advertising and promotional and
similar activities by AT&T PCS or its Affiliates or any Cash Equity Investor or
any of its Affiliates.

          (b)  With respect to the markets listed on Schedules 1 and 2 to the
Roaming Agreement, each of AT&T PCS and the Company shall, and shall cause each
of its Affiliates to, in its and such Affiliates' capacity as Home Carrier: (i)
program and direct its authorized dealers to program the subscriber equipment
provided by it or such 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 "Affiliate," "Home Carrier" and "Serving Carrier"
shall have the meanings ascribed thereto in the Roaming Agreement.

     8.7  Other Business; Duties; Etc. Except to the extent expressly set
          ----------------------------
forth in Section 8.6, AT&T PCS, TWR Cellular and each Cash Equity Investor and
any Person affiliated with AT&T PCS, TWR Cellular or a Cash Equity Investor may
engage in or possess an 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, TWR Cellular or a Cash Equity
Investor or a Person affiliated with AT&T PCS, TWR Cellular or a Cash Equity
Investor develops inventions which are patentable or are otherwise trade secrets
relevant to the Business, AT&T PCS, TWR Cellular 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, TWR Cellular
or a Cash Equity Investor or any Person affiliated with AT&T PCS, TWR Cellular
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

                                      56


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 or to any Stockholder
for its good faith reliance on the provisions of this Section 8.7.

     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
Agreements.

          (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 (including TWR
Cellular) 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' (including TWR
Cellular's) obligations under Section 8.6 with respect to any Overlap Territory,
provided that the obligations of AT&T PCS (including TWR Cellular) 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 (including TWR Cellular) (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 (including TWR Cellular).
Notwithstanding the foregoing, in the event that the Company exercises its right
pursuant to Section 6.1 to convert all of the shares of Company Stock owned by
AT&T PCS (including TWR Cellular) into Series B Preferred Stock, the reference
in this Section 8.8(c) to the "Overlap Territory" shall be deemed to refer to
the Territory.

     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

                                      57


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. AT&T
PCS may develop a roaming clearinghouse for AT&T Licensees, including the
Company, pursuant to which the Company's subscribers that are roaming on PCS or
Cellular Systems with which AT&T PCS or any of its Affiliates have entered into
a roaming agreement will be identified on such PCS or Cellular System as an AT&T
PCS subscriber, and settlement of roaming accounts for such Company subscribers
would be effected first between AT&T PCS and such PCS or Cellular System and
then settled between AT&T PCS and the Company. In the event AT&T PCS provides
such roaming clearinghouse to the Company, the per-subscriber handling charge to
the Company shall be commercially reasonable.

     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,
substantially in the form of Exhibit C.

     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, substantially in
the form of Exhibit C to the Securities Purchase Agreement, with 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 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's 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

                                      58


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).

     8.12 Non-Solicitation.
          ----------------

          (a)  AT&T PCS hereby covenants and agrees that from and after the date
hereof until six months after the date on which it shall cease to own any Equity
Securities that neither AT&T PCS nor its Affiliates (including TWR Cellular)
shall solicit for employment any employee of the Company; provided however that,
                                                          -------- -------
nothing contained in this Section 8.12(a) shall prevent AT&T PCS or its
Affiliates (including TWR Cellular) from engaging in a general solicitation for
employment that is not directed at employees of the Company.

          (b)  The Company hereby covenants and agrees that from and after the
date hereof until six months after the date on which AT&T PCS or its Affiliates
(including TWR Cellular) shall cease to own any Equity Securities that neither
the Company nor its Affiliates (including TWR Cellular) shall solicit for
employment any employee of the AT&T PCS or its Affiliates; provided, however
that nothing contained in this Section 8.12(b) shall prevent the Company or its
Affiliates (including TWR Cellular) from engaging in a general solicitation for
employment that is not directed at employees of AT&T PCS and its Affiliates.

     8.13 Co-Location. Except in any portion of the Territory as to which the
          -----------
provisions of Section 8.6 shall have been terminated: (a) the Company agrees to
permit on commercially reasonable terms AT&T PCS and its Affiliates (including
TWR Cellular) to install, operate and maintain cell site equipment owned or used
by AT&T PCS and its Affiliates (including TWR Cellular) in their respective
businesses on the towers, buildings and other locations at which the Company's
cell site equipment is installed, operated and maintained, and (b) AT&T PCS and
its Affiliates (including TWR Cellular) agree to permit on commercially
reasonable terms the Company to install, operate and maintain cell site
equipment owned or used by the Company in its business on the towers, buildings
and other locations at which AT&T PCS and its Affiliates (including TWR
Cellular) cell site equipment is installed, operated and maintained.

          ---------------------------------------

     9.1  After Acquired Shares; Recapitalization.
          ---------------------------------------

          (a)  All of the provisions of this Agreement shall apply to all of the
shares of Equity Securities now owned or hereafter issued or transferred to a
Stockholder or to his, her or

                                      59


its Affiliated Successors in consequence of any additional issuance, purchase,
exchange or reclassification of shares of Equity Securities, corporate
reorganization, or any other form of recapitalization, or consolidation, or
merger, or share split, or share dividend, or which are acquired by a
Stockholder or its Affiliated Successors in any other manner.

          (b)  Whenever the number of outstanding shares of Equity Securities is
changed by reason of a stock dividend or a subdivision or combination of shares
effected by a reclassification of shares, each specified number of shares
referred to in this Agreement shall be adjusted accordingly.

     9.2  Amendment of Restated Certificate. Whenever the number of shares of
          ---------------------------------
authorized Common Stock is not sufficient in order to issue shares of Common
Stock upon conversion of Preferred Stock in accordance with the Restated
Certificate, (i) the Company shall promptly amend the Restated Certificate in
order to authorize a sufficient number of shares of Common Stock, and (ii) each
Stockholder agrees to vote its shares of Preferred Stock and Common Stock in
favor of such amendment.

          --------------------------------------------------
representing the shares of Equity Securities now or hereafter held by a
Stockholder (including any such certificate delivered upon conversion of the
Preferred Stock) or delivered in substitution or exchange for any of the
foregoing certificates shall be stamped with legends in substantially the
following form:

          (a)  "The shares represented by this Certificate are subject to a
Stockholders' Agreement dated as of July 17, 1998, a copy of which is on file at
the offices of the Company and will be furnished by the Company to the holder
hereof upon written request. Such Stockholders' Agreement provides, among other
things, for the granting of certain restrictions on the sale, transfer, pledge,
hypothecation or other disposition of the shares represented by this
Certificate, and that under certain circumstances, the holder hereof may be
required to sell the shares represented by this Certificate. By acceptance of
this Certificate, each holder hereof agrees to be bound by the provisions of
such Stockholders' Agreement. The Company reserves the rights to refuse to
transfer the shares represented by this Certificate unless and until the
conditions to transfer set forth in such Stockholders' Agreement have been
fulfilled"; and

          (b)  "The securities represented by this Certificate have been
acquired for investment and have not been registered under the Securities Act of
1933, as amended (the "Act"), or under any state securities or `Blue Sky' laws.
Said securities may not be sold, transferred, assigned, pledged, hypothecated or
otherwise disposed of, unless and until registered under the Act and the rules
and regulations thereunder and all applicable state securities or `Blue Sky'
laws or exempted therefrom under the Act and all applicable state securities or
`Blue Sky' laws."

                                      60


     Each Stockholder agrees that he, she or it will deliver all certificates
for shares of Equity Securities owned by him, her or it to the Company for the

in addition to being entitled to exercise all of the rights provided herein or
in the Restated Certificate or granted by law, including recovery of damages,
equitable relief, including specific performance and injunctive relief, may be
used to enforce the provisions of this Agreement.

          -------------------------------------

               (a)  This Agreement constitutes the entire agreement among the
parties with respect to the subject matter hereof and supersedes all other prior
agreements and understandings, both written and oral, among the parties or any
of them with respect to the subject matter hereof.

               (b)  No change or modification of this Agreement shall be valid,
binding or enforceable unless the same shall be in writing and signed by the
Company and the Beneficial Owners of a majority of the shares of Class A Voting
Common Stock, including

                                      62


AT&T PCS, 66 2/3% of the Class A Voting Common Stock Beneficially Owned by the

Beneficially Owned by the Management Stockholders; provided, however, that in
                                                   --------  -------
the event any party hereto shall cease to own any shares of Equity Securities
such party hereto shall cease to be a party to this Agreement and the rights and
obligations of such party hereunder shall terminate, except to the extent
otherwise provided in Section 4.7(a) with respect to any Unfunded Commitment.

               (c)  Whenever in this Agreement the consent or approval of a
Stockholder is required, except as expressly provided herein, such consent or
approval may be given or withheld in the sole and absolute discretion of each
Stockholder.

     12.3 Term.
          ----

               (a)  Subject to Sections 12.3(b), 12.3(c) and 12.4, this
Agreement shall terminate upon the earliest to occur of any of the following
events:

                    (i)   The consent in writing of all of the parties hereto;
or

                    (ii)  The expiration of eleven (11) years from the date of
execution and delivery of this Agreement; or

                    (iii) One Stockholder shall Beneficially Own all of the

               (b)  Notwithstanding anything contained herein to the contrary,
(i) the provisions of Sections 3.2, 3.3, 3.4, 3.5, 4.1(a), 4.5 (other than
Section 4.5(b)), 7.1, 7.2 and 7.6 shall terminate on the earlier to occur of a
termination pursuant to Section 12.3(a) and the IPO Date, (ii) the provisions of
Sections 3 and 4 shall terminate on the earlier to occur of a termination
pursuant to Section 12.3(a) and the expiration of ten (10) years from the date
hereof, (iii) the provisions of Sections 3.1(e) (relating to AT&T PCS' right to
approve the directors selected by the holders of the Voting Preference Stock
pursuant to Section 3.1(e)(ii) and any replacement for Messrs. Vento or Sullivan
to the Board of Directors), 3.11(a) (relating to AT&T PCS' right to approve the

and any individuals selected by the Management Stockholders and any replacement

terminate, and neither the Company nor any Stockholder shall be required to
obtain AT&T PCS's prior written consent as required under such Sections, on the
earlier to occur of (i) a termination pursuant to Section 12.3(a) and (ii) (x)
with respect to the period prior to the eighth anniversary of the date hereof,
the date on which AT&T PCS and TWR Cellular shall cease to Beneficially Own, in
the aggregate, more than two-thirds of the number of shares of Series A
Preferred Stock that AT&T PCS and TWR Cellular Beneficially Own, in the
aggregate, on the date hereof and (y) with respect to the period after the
eighth anniversary of the date hereof on which AT&T PCS and TWR Cellular shall
cease to Beneficially Own, in the aggregate, more than two-thirds of the number
of shares of Class A Voting Common Stock that AT&T PCS and TWR Cellular

                                      63


Beneficially Owns, in the aggregate, on such eighth anniversary date, (iv) the
provisions of Section 3.1 shall terminate on the later to occur of (x) the date
that the holders of shares of Voting Preference Stock shall vote as a class with
holders of Class A Voting Common Stock, and (y) immediately prior to the IPO
Date; it being understood that in such event the Board of Directors on and as of
the IPO Date shall be determined in accordance with Section 3.11 and (v) the
provisions of 3.6 shall terminate on the date that the holders of shares of
Voting Preference Stock shall vote as a class with holders of Class A Voting
Common Stock. Notwithstanding anything contained herein to the contrary, the
provisions of Section 3.11(a)(ii), (b), (c) and (d) shall terminate on the
earlier to occur of a termination pursuant to Section 12.3 (a) and the date
after the IPO Date.

          (c)  (i)  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 the date hereof, the number
of directors the Cash Equity Investors shall be permitted to designate under
Section 3.1(a) shall be reduced to one, or (II) one-quarter of the number of
shares of Common Stock Beneficially Owned by the Cash Equity Investors on the
date hereof, the provisions of Section 3.1(a) and the provisions of Sections
3.1(e) (relating to the Cash Equity Investors' right to approve the directors
selected by the holders of the Voting Preference Stock pursuant to Section
3.1(e)(i) and (ii)) and the right to approve any director that replaces Messrs.
Vento or Sullivan on the Board of Directors shall terminate, and neither the
Company nor any Stockholder shall be required to obtain the Cash Equity
Investors' prior written consent as required under such Sections. In the event
the number of directors the Cash Equity Investors are entitled to designate is
reduced pursuant to Section 12.3(c)(i)(I), two of the directors designated by
the Cash Equity Investors under Section 3.1(a)(i) shall resign (or the other
directors 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) and 3.1(e) are terminated pursuant to
Section 12.3(c)(i)(II), the directors designated by the Cash Equity Investors
pursuant to Section 3.1(a) and the directors designated pursuant to Section
3.1(e)(i) shall resign (or the other directors 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 is
reduced to seven (7) individuals. The holders of the Voting Preference Stock
shall thereafter have the right to designate three (3) individuals to the Board
of Directors provided each such individual is acceptable to AT&T PCS (so long as
AT&T PCS and TWR Cellular continues to Beneficially Own, in the aggregate, more
than two-thirds of the Common Stock Beneficially Owned by AT&T PCS and TWR
Cellular, in the aggregate, on the date hereof). For all purposes of this
Agreement (other than Section 3.1(a)), all references in this Agreement to
directors designated pursuant to Section 3.1(e)(ii) shall thereafter be deemed
to refer to the three (3) directors designated pursuant to the immediately
preceding sentence.

               (ii)  Notwithstanding anything contained herein to the contrary,
in the event that the composition of the Board of Directors shall be determined
in accordance with Section 3.11 and the Cash Equity Investors shall Beneficially
Own less than (I) one-half but

                                      64


more than one-quarter of the number of shares of Common Stock Beneficially Owned
by the Cash Equity Investors on the date hereof, then notwithstanding the
provisions of Section 3.11 the number of directors the Cash Equity Investors
shall be permitted to designate under Section 3.11(a), shall be reduced to one,
or (II) one-quarter of the number of shares of Common Stock Beneficially Owned
by the Cash Equity Investors on the date hereof, the provisions of Section
3.11(a), shall terminate. In the event that the composition of the Board of
Directors shall be determined in accordance with Section 3.11 and the number of
directors the Cash Equity Investors are entitled to designate is reduced
pursuant to Section 12.3(c)(ii)(I), one of the directors designated by the Cash
Equity Investors under Section 3.11(a)(i) shall resign (or the other directors
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
composition of the Board of Directors shall be determined in accordance with
Section 3.11 and the provisions of Section 3.11(a) are terminated pursuant to
Section 12.3(c)(ii)(II), the directors designated by the Cash Equity Investors
pursuant to Section 3.11(a) shall resign (or the other directors 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 is reduced by two (2) individuals. Messrs. Sullivan and Vento (in
each case so long as he is an officer of the Company) shall thereafter have the
right to designate two (2) individuals to the Board of Directors provided such
individual is acceptable to AT&T PCS (so long as AT&T PCS and TWR Cellular
continue to Beneficially Own more than two-thirds of the Common Stock
Beneficially Owned by AT&T PCS and TWR Cellular, in the aggregate, on the date
hereof). For all purposes of this Agreement (other than Section 3.11(a)), all
references in this Agreement to directors designated pursuant to Section
3.11(a)(ii) shall thereafter be deemed to refer to the two (2) directors
designated pursuant to the immediately preceding sentence.

     12.4 Survival. Nothing contained in Section 12.3 shall impair any rights or
          --------
obligations of any party hereto arising prior to the time of the termination of
this Agreement, or which may arise by an event causing the termination of this
Agreement. The provisions of Section 5 shall survive any termination of this
Agreement pursuant to Section 12.3 and shall continue in full force and effect
until the twentieth anniversary of the date hereof. The provisions of Section
7.7 and Article 12 shall survive the termination of this Agreement.

     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.

                                      65


     12.6  Obligations Several.  The obligations of each Stockholder under this
           -------------------
Agreement shall be several with respect to each such Stockholder.

     12.7  Governing Law.  This Agreement shall be governed and construed 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(ies) 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.

                                      66


                 (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(ies) 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, 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
1-14 (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 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

                                      67


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 12.1.

     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, 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,

                                      68


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 By-Laws. The Stockholders agree that the terms of this
            --------------------
Agreement shall supersede any inconsistent provision that is contained in the
Restated By-Laws and, to the extent required by Delaware law or the Restated By-
Laws, 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 By-
Laws.

     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 on behalf

                                 Core Features
                                 -------------

Below is a list and description of the Core Features that Licensee agrees to
implement in accordance with Section 8.2 of this Agreement.  These definitions
are functional descriptions of the Core Features, and the parties agree that
such Core Features shall be implemented using the Critical Network Elements
identified in Schedule XI hereto.  Licensee further agrees to implement
additional features in accordance with Section 8.2 of this Agreement.

1.   Call Delivery

     This capability permits a PCS customer to receive incoming calls to his or
her phone while in his or her home market or while roaming in any part of the
Licensee's Wireless Network or the AWS Wireless Network (together, the "Mobile
Wireless Network").

2.   Roaming - Do Not Disturb

     This capability permits a PCS customer, who would normally receive all
incoming calls while visiting a Mobile Switching Center that is part of the
Mobile Wireless Network, to temporarily inhibit the delivery of such calls.
Activating this capability has no impact on the PCS customer's ability to
originate calls or on the PCS customer's ability to receive calls via the roamer
access ports.

3.   Call Forwarding

     A.  Call Forwarding Immediate

     This capability permits a PCS customer to send all incoming calls destined
     for the PCS customer's PCS phone to another phone number specified by the
     PCS customer.  Activating this capability has no impact on the PCS
     customer's ability to originate calls.  When this capability is activated,
     calls are forwarded regardless of whether the PCS customer is located
     within his or her local market or whether the customer is roaming outside
     of such local market.

     B.  Call Forwarding Busy

     This capability permits a PCS customer to send all incoming calls destined
     for his or her PCS phone to another phone number specified by the PCS
     customer when the PCS customer is engaged in a call.


     C.  Call Forwarding No Answer

     This capability permits a PCS customer to send all incoming calls destined
     for his or her PCS phone to another phone number specified by the PCS
     customer when the PCS customer does not answer or when the PCS customer's
     PCS phone does not respond to a page.

4.   Call Waiting

     This capability permits a PCS customer to receive incoming calls even
though a call may already be in progress.

5.   Voicemail

     This capability forwards those PCS customer's incoming calls which are not
answered by the PCS customer, and for which no other explicit treatment has been
activated (for example, those described in items above), to a voice storage and
retrieval system.  This capability also permits a PCS customer to subsequently
retrieve messages from the PCS customer's voice mail box.

6.   Three Way Calling

     This capability permits a PCS customer to add a third party to an active
two party call.

7.   Message Waiting Indicator

     This capability is an enhancement to PCS voice mail, and provides the PCS
customer with the current status of the number of unheard voice mail messages
waiting in his or her PCS voice mail box.

8.   Calling Number Identification

     This capability identifies for the PCS customer either the telephone number
or the stored name (in the PCS phone) of the person who is calling.  It also
permits a PCS customer to inhibit the ability of a person to whom the PCS
customer is placing a call from identifying either the telephone number or the
name of such PCS customer who is placing the call.

9.   Wireless Office Service (WOS)

     A.  PCS/PBX Interworking

     This capability permits WOS customers to have just one published number
     that delivers all incoming calls to both the PCS and PBX phone.

                                       2


     B.  Private Number Plan

     This capability permits a defined group of customers to call defined
     private network extensions by using an abbreviated unique dialing pattern
     (four digit dialing).

     C.  Private Networks

     This capability permits a WOS customer to have his or her own private or
     semiprivate PCS system.

     D.  Location ID

     This capability permits the PCS customer to identify the nature of the
     system (private, public, or residential) that the PCS customer is using, by
     displaying the system's name on the PCS phone.

10.  Sleep Mode

     This capability permits an IS 136 PCS phone to operate in a power saving
mode when camping on an IS 136 system, thereby allowing the battery standby time
to increase.

11.  PCS Messaging

     This capability will permit a caller to deliver both numeric and
alphanumeric messages of up to eighty characters to an IS 136 PCS phone.  If the
PCS customer to whom the message has been delivered has his or her phone off or
is not in the IS 136 coverage area, then messages are stored for future
delivery.

     MessageFlash software permits alphanumeric messages to be sent from a
computer via a standard modem to the customer.

     E-Mail messaging teleservice allowing an IS-136 phone to have an E-Mail
address.

12.  Authentication

     This capability allows for the validation of the IS-136 phone's identity.

     Text Dispatch Service permits people to call an operator (provided by or on
behalf of the Company) and dictate a message which can then be converted to an
alphanumeric message and delivered to the customer.

     Cut Through Paging permits people to send a numeric message while listening
to the customer's voicemail greeting.

                        Quality and Reporting Standards
                        -------------------------------

General Overview

This Schedule VII sets out the Network and Reporting Standards with which
Licensee shall comply pursuant to Section 8.2 of this Agreement. These Standards
set out the network performance metrics and the process by which such metrics
will be established, measured and reported. All metrics which represent a
defined standard of quality for acceptable network operations have, or will
have, specific targets which the Licensee must comply with in accordance with
the following network standards.

I.  NETWORK STANDARDS

There are three categories of Network Standards: network quality (the "Network
Quality Category"); system performance (the "System Performance Category"); and
audio quality (the "Audio Quality Category") (each hereafter referred to
generally as a "Category"). For each Category of Network Standards, specific
metrics have been identified to measure performance in each such Category. The
detailed description of how to measure and interpret the metrics for each
Category is set out in the following AWS documents (each referred to generally
as a "Network Standards Document"):

 .    Network Quality Category: Document ES-4034, Revision 1.1, dated July 30,
     ------------------------
     1997 entitled "Network Quality Scorecard User Guide" (as referred to as the
     "Network Quality Standards Document"). This document is a collection of key
     network performance and traffic indicators (metrics) that are measured and
     reported on a regular basis. Included in this category, Licensee shall
     perform the ANS Consistency Test, as attached to this Schedule VII.

 .    System Performance Category: OSS draft document, Revision 0.7, dated June
     ---------------------------
     17, 1997 entitled "Key Metrics for System Performance Document" (as
     referred to as the "System Performance Standards Document"). This document
     identifies the network-wide key metrics for Ericsson and Lucent switching
     systems, as well as cell sites, which will provide a high level assessment
     of the system.

 .    Audio Quality Category: Document PP-4027E, Revision 1.1, dated May 30, 1996
     ----------------------
     entitled "Audio Quality Measurement (AQM)" (as referred to as the "Audio
     Quality Standards Document"). This document provides the basis for
     assessing the quality of RF transmission by describing the standards for
     performing audio quality measurements and the reporting of their results.
     AWS measures the metrics for the Audio Quality Category using the "Radio
     Quality Scorecard". The Radio Quality Scorecard is comprised of performance
     statistics derived from driving the PCS system using the Buzzard tool or a
     tool with similar measurement and reporting capability.


These Network Standards Documents are collectively attached to this Schedule VII
which, subject to the terms and conditions of this Agreement including, without
limitation, this Schedule VII, is hereby incorporated into and forms a part of
this Agreement. In the event of any inconsistency between any part of a Network
Standards Document and the provisions of this Schedule VII, the provisions of
this Schedule VII shall govern.

Notwithstanding anything else in this Agreement including, without limitation,
this Schedule VII, the parties acknowledge and confirm that the Network
Standards Documents represent the standards and metrics currently identified by
AWS as applicable to each Category. Target values for key quality related
metrics are contained herein and Licensee agrees to comply with the specific
metric target values as specified in Schedule VII.

In addition, the parties acknowledge and confirm that the Network Standards
Documents are subject to revision and the Licensee shall comply with subsequent
revisions to these Network Standards Documents, as well as with Call Center
Quality Standards which will constitute an additional Category once they are
formally implemented, in accordance with Section 8.2 of this Agreement.

Set out below is a brief description of each Category of Network Standard and
the currently established metrics for each such Category.

II.  TARGETS FOR NETWORK STANDARDS

Licensee shall meet the following targets for key metrics which represent
overall network and system quality. These targets are subject to revision and
shall be implemented in accordance with Section 8.2 of this Agreement.

 .    % Established Calls: The percentage of call attempts to and from a mobile
     -------------------
     phone that result in a successful voice channel assignment. The target goal
     for this metric is 93%.

 .    % Dropped Calls: The percentage of established calls, as defined below,
     ---------------
     which terminate abnormally. The target, goal for this metric is a drop call
     rate of 1.7% or less.

 .    % Handoff Failures: The target goal for this metric is a handoff failure
     ------------------
     rate of 1.5%.

 .    Failures per Erlang: The ratio of failed calls to carried traffic, where
     -------------------
     failed calls are measured utilizing switch counters for originating and
     terminating traffic, and carried traffic is measured in erlangs. The target
     goal for this metric is 1.68.

 .    Switch Outage Time: The amount of time (in minutes) in a month when
     ------------------
     subscribers are impacted by a cellular switch outage. Target for this
     metric is 10 minutes per switch per

                                       2


     year, with all ten minutes occurring the maintenance window between 12:00
     am and 5:00 am.

 .    % Blocking - Cell Routes: Percentage of time all cellular traffic channels
     ------------------------
     (voice paths in a trunk group) are unavailable within a given measurement
     interval. Target for this metric is 5%.

 .    % Blocking- - Network Routes: Percentage of time all network traffic
     ----------------------------
     channels are unavailable within the measurement interval. Target for this
     metric is 5%.

 .    ANS Consistency Test: The percentage of successful ANS feature deliveries,
     --------------------
     based on the following sequence: feature activation/deactivation (when
     applicable), test call, correct response, and call termination. The target
     goal for this metric is 96% for all ANS features. This target metric
     includes feature delivery failures due to call processing failures (i.e.
     call delivery, call origination, handoff failures, or dropped calls. These
     failures are estimated to be approximately 4%.)

III. REPORTING STANDARDS

Licensee agrees to comply with the reporting requirements as specified in the
Network Standards Documents and as specified below:

 .    Except as specified Audio Quality Network Standards, Licensee will submit
     the metric reports required pursuant to this Schedule VII (the "Results")
     to AWS no less than quarterly.

 .    With respect to Audio Quality Network Standards, Licensee shall only submit
     quarterly Results for markets with 10,000 or more subscribers; for markets
     with less than 10,000 subscribers, Licensee shall only submit Results on a
     semi-annual basis.

 .    Licensee shall submit all Results by the fifteenth day of the month
     following the end of the applicable reporting period.

 .    Licensee will report the Results to AWS on an aggregated national basis;
     the aggregated national Results will reflect the distribution of the metric
     measured across Licensee's Territory. Licensee may also be required to
     provide a breakdown, by market, of any metric.
