expenses are incurred by such Indemnified Party; provided, however, that if an
                                                 --------  -------
Indemnified Party is reimbursed hereunder for any expenses, such reimbursement
of expenses shall be refunded promptly to the Company to the extent it is
finally judicially determined that the Liabilities in question resulted
primarily from the willful misconduct, bad faith or gross negligence of such
Indemnified Party.

          7.2 Notification. Each Indemnified Party under this Article 7 will,
              ------------
promptly after the receipt of notice of the commencement of any action or other
proceeding against such Indemnified Party in respect of which indemnity may be
sought from the Company under this Article 7, notify the Company in writing of
the commencement thereof. The failure of any Indemnified Party to so notify the
Company of any such action shall not relieve the Company from any liability
which it may have to such Indemnified Party (a) other than pursuant to this
Article 7, or (b) under this Article 7 unless, and only to the extent that, such
omission results in the Company's forfeiture of substantive rights or defenses.
In case any such action or other proceeding shall be brought against any
Indemnified Party and it shall notify the Company of the commencement thereof,
the Company shall be entitled to participate therein and, to the extent that it
may wish, to assume the defense thereof, with counsel reasonably satisfactory to
such Indemnified Party; provided, however, that any Indemnified Party may, at
                        --------  -------
its own expense, retain separate counsel to participate in such defense.
Notwithstanding the foregoing, in any action or proceeding in which both the
Company and an Indemnified Party is, or is reasonably likely to become, a party,
such Indemnified Party shall have the right to employ separate counsel at the
Company's expense and to control its own defense of such action or proceeding
if, in the reasonable opinion of counsel to such Indemnified Party, (a) there
are or may be legal defenses available to such Indemnified Party or to other
indemnified parties that are different from or additional to those available to
the Company, or (b) any conflict or potential conflict exists between the
Company and such Indemnified Party that would make such separate representation
advisable; provided, however, that in no event shall the Company be required to
           --------  -------
pay fees and expenses under this Article 7 for more than one firm of attorneys
in any jurisdiction in any one legal action or group of related legal actions.
The Company agrees that the Company will not, without the prior written consent
of the Purchaser, settle, compromise or consent to the entry of any judgment in
any pending or threatened claim, action or proceeding relating to the matters
contemplated hereby (if any Indemnified Party is a party thereto or has been
actually threatened to be made a party thereto) unless such settlement,
compromise or consent includes an unconditional release of the Purchaser and
each other Indemnified Party from all liability arising or that may arise out of
such claim, action or proceeding. The rights accorded to Indemnified Parties
hereunder shall be in addition to any rights that any Indemnified Party may have
at common law, by separate agreement or otherwise.

          7.3 Registration Rights Agreement. Notwithstanding anything to the
              -----------------------------
contrary in this Article 7, the indemnification and contribution provisions of
the Registration Rights Agreement shall govern any claim made with respect to
registration statements filed pursuant thereto or sales made thereunder.

               --------------------
each of its Subsidiaries to comply, in all material respects with all
Requirements of Law and with the directions of any Governmental Authority having
jurisdiction over it or its business, except the failure to so comply would not
have a material adverse effect on the Condition of the Company.

          8.6  Notices. Upon knowledge of the Chief Executive Officer, the
               -------
President or the Chief Financial Officer of the Company of the events described

and keep available out of its authorized Class A Common Stock, solely for the
purpose of issue or delivery upon conversion of the Preferred Shares, and (ii)
keep available out of its authorized Class A Common Stock, solely for the
purpose of issue or delivery upon exercise of the Warrants as provided in the
Charter Amendment and the Warrants, such number of shares of Class A Common
Stock as shall then be issuable or deliverable upon the conversion of all
outstanding Preferred Shares and upon the exercise of all outstanding Warrants.
Such shares of Class A Common Stock shall, when issued or delivered in
accordance with the Charter Amendment or Warrants, be duly and validly issued

such reasonable times during normal business hours and as often as may be
reasonably requested, upon reasonable advance notice to the Company, and all at
the expense of the Purchaser.

          8.9  Registration and Listing. If any shares of Class A Common Stock
               ------------------------
required to be reserved for purposes of conversion of the Preferred Shares or
exercise of the Warrants, as provided in the Charter Amendment or the Warrants,
require registration with or approval of any Governmental Authority under any
Federal or state or other applicable law before such Class A Common Stock may be
issued or delivered upon conversion or exercise, the Company will endeavor in
good faith and as expeditiously as possible to cause such Class A Common Stock
to be duly registered or approved, as the case may be, unless such registration
or approval is required solely because of a breach of the Purchaser's
representation contained in Section 6.5. In the event that the Class A Common
Stock is quoted or listed on any national securities exchange, the Company, if
permitted by the rules of such system or exchange, will quote or list and keep
quoted or listed on such exchange, upon official notice of issuance, all Class A
Common Stock issuable or deliverable upon conversion of the Preferred Shares or
upon exercise of the Warrants. In addition, at the request of the Purchaser, the
Company will endeavor in good faith and as expeditiously as possible, to use its
best efforts to obtain private placement numbers for the Preferred Shares and
the Class A Common Stock issued upon conversion of the Preferred Shares or upon
exercise of the Warrants, assigned by the CUSIP Service Bureau of Standard &
Poor's ratings group and make such securities PORTAL and DTC eligible.

Sprint PCS.

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

          The Company hereby covenants and agrees with the Purchaser and each
Holder that so long as any Preferred Shares are outstanding:

               --------------------------
consolidate with or into, or convey, transfer, lease or otherwise dispose of
(whether in one transaction or in a series of transactions) all or substantially
all of its assets (whenever acquired), and the Company shall not allow any of

the Company or another Subsidiary of the Company, except the Company may

assets to, any Person if:

                                                                              33

               (a)  The corporation or partnership formed by such consolidation
or surviving such merger or the Person which acquires all or substantially all
of the assets of the Company shall be (after giving effect to such transaction)
a Solvent corporation or partnership organized or formed, as the case may be,
and existing under, the laws of the United States, any state thereof, or the
District of Columbia, and shall expressly assume in writing all of the
obligations of the Company under this Agreement, the Preferred Shares, the
Registration Rights Agreement, the Warrants and the Shareholders Agreement;

               (b)  immediately after giving effect to such transaction, no
default under, or breach of, the provisions of Articles 8 and 9 exists;

               (c)  the corporation or partnership formed by or surviving any
such transaction or the Person which acquires all or substantially all of the
assets of the Company shall have a Consolidated Net Worth at least equal to the

               (d)  the Company shall have furnished to the Holders (i) an
opinion of counsel satisfactory to a majority in interest of the holders of
Preferred Stock addressing the matters (other than Solvency) set forth in clause
(a) above, and (ii) a certificate of the Chief Financial Officer of the Company
to the effect that such transaction has been consummated in compliance with the
foregoing requirements; provided that nothing in this Section 9.1 shall affect
the rights of any Holder under this Agreement, the Preferred Shares, the
Registration Rights Agreement, the Warrants and the Shareholders Agreement.

          9.2  Transactions with Affiliates.  Except as described in the
               ----------------------------
Offering Memorandum under the caption "Certain Relationships and Related
Transactions -- Affiliate Transactions", the Company shall not, and shall not
permit any of its Subsidiaries to, enter into any transaction with any Affiliate
of the Company or of any such Subsidiary, unless such transaction is on terms no
less favorable to the Company or such Subsidiary as would be obtainable by the
Company or such Subsidiary at the time of such transaction in an arm's- length
transaction with a Person that is not an Affiliate of the Company or of such
Subsidiary. The Company shall not, and shall not permit any of its Subsidiaries
to, amend or modify any material provision of any existing contract, agreement
or commitment, whether written or oral, between the Company or any of its
Subsidiaries, on the one hand, and an Affiliate of the Company or of any such
Subsidiary, on the other hand, unless such amendment or modification is on terms
no less favorable to the Company or such Subsidiary as would be obtainable by
the Company or such Subsidiary at the time of such amendment or modification in
an arm's-length transaction with a Person that is not an Affiliate of the
Company or of such Subsidiary.

          9.3  No Inconsistent Agreements. Neither the Company nor any of its
               --------------------------

its terms restricts or prohibits the ability of the Company to issue Common

shareholders without any notice to, consent from, or payment to any Holder.


                                  Article 10

                                 DISPOSITIONS
                                 ------------

          10.1 Dispositions by the Purchaser.
               -----------------------------

               (a)  In the event that, prior to an IPO, the Purchaser shall
desire to sell or otherwise transfer any of the Preferred Shares, the Purchaser
shall give the Company written notice of its desire to sell such securities,
which notice shall specify (i) the number of such securities the Purchaser
desires to sell, (ii) the price at, and the terms and conditions on, which the
Purchaser desires to sell such securities, and (iii) the identity of all Persons
whom the Purchaser intends to contact in connection with the proposed sale (the
"Contact List"), and the Purchaser shall offer to sell such securities to the
 ------------
Company at such price and on such terms and conditions. If, within thirty (30)
days of receiving such notice, the Company does not accept such offer in
writing, the Purchaser shall be free for a period of six months to enter into a
definitive agreement to sell such securities to any Person on the Contact List
at a price not less than the price offered to the Company, and on terms and
conditions substantially equivalent to those offered to the Company. If the
Purchaser does not sell such securities in such a manner within such six-month
period, the Purchaser may not thereafter sell or transfer such securities
without again complying with the provisions of the first sentence of this
Section 10.1(a). If, within the thirty-day period specified in the preceding
sentence, the Company does accept such offer in writing, then the Company shall
purchase such securities as promptly as is reasonably practicable, but in no
event later than thirty (30) days following such acceptance. If, after such
acceptance, the Company for whatever reason fails to purchase such securities on
or prior to the date specified in the preceding sentence, the Purchaser may,
among other remedies available to it, sell such securities to any Person on the
Contact List at any price and on any terms.

               (b)  Notwithstanding anything in this Section 10.1 to the
contrary, the Purchaser may, at any time and from time to time, sell or
otherwise transfer Common Stock or Preferred Shares (i) pursuant to an exchange
offer or a tender offer not opposed by a majority of the Company's Board of
Directors, (ii) pursuant to any all cash tender offer
<PAGE>

                                                                              35

made by any Person for all of the issued and outstanding Common Stock, (iii)
pursuant to the Registration Rights Agreement, (iv) to any of the Purchaser's
Affiliates, or (v) to the Purchaser's limited partners, if any, pursuant to a
pro rata distribution; provided, however, that any Affiliates (or limited
                       --------  -------
partners, if any) of the Purchaser to which such securities are transferred
shall agree to be bound by all of the transfer restrictions set forth in this
Section 10.1.

               (c)  Except as otherwise provided in Section 10.1(b), any
securities transferred by the Purchaser shall not thereafter be subject to the
provisions of this Section 10.1.

          10.2 Equity Put Option.
               -----------------

               (a)  If the holders of a majority of the Preferred Stock, Series
A require the Company to redeem their shares of Preferred Stock, Series A
pursuant to Section 10.2 of the Fund Securities Purchase Agreement, all Holders
of the Preferred Shares (the "Participating Holders") shall by written notice to
the Company (a "Demand Notice"), require the Company to redeem all of the then
                -------------
outstanding Preferred Shares at a redemption price per share of Common Stock
into which such Preferred Shares are convertible at the time of redemption equal
to the Put Price (it being understood that Preferred Stock, Series A is
convertible into Class A or Class B Common Stock depending on who the holder is
and Preferred Stock, Series B is convertible into Class A Common Stock;
provided, however, that the right to require redemption pursuant to this Section
--------  -------
10.2 shall expire and be of no further force or effect following the
consummation of an IPO. Notice of a request for redemption pursuant to this
Section 10.2 shall be sent in accordance with Section 11.2 of this Agreement.
The Company shall redeem the Preferred Stock required to be redeemed pursuant to
such Demand Notice no later than ninety (90) days after the Per Share Equity
Value is determined in accordance with Section 10.2(c), but in no event later
than the 180th day after the Company receives such Demand Notice (the
"Redemption Date"). In the event that the Company redeems less than all of the
 ---------------
Preferred Stock required to be redeemed pursuant to such Demand Notice,
redemption pursuant to this Section 10.2 shall be pro rata among the
Participating Holders. On or prior to the Redemption Date, each Participating
Holder shall be entitled to receive payment of the Per Share Equity Value for
each of the Preferred Shares such Participating Holder required be redeemed on
the Redemption Date, in immediately available funds upon actual delivery to the
Company or its transfer agent of such Preferred Share certificates.
Notwithstanding anything to the contrary in this Section, in the event the
Company fails to redeem any Preferred Stock required to be redeemed pursuant to
a Demand Notice on the Redemption Date solely as a result of the terms of any
Indebtedness for borrowed money of the Company prohibiting such redemption and
the Company is unable to obtain waivers to such prohibition or to refinance such
Indebtedness (a "Prohibitive Event"), then the Company shall pay such amount as
                 -----------------
soon as possible, but the Participating Holders' sole remedy for such failure
shall be pursuant to Section 10.2(b); provided that the Company shall use its
commercially reasonable efforts to obtain waivers to the terms of any
Indebtedness for borrowed money of the Company prohibiting such
<PAGE>

                                                                              36

redemption or to refinance such Indebtedness. If the Company fails to redeem any
of the Preferred Stock required to be redeemed pursuant to a Demand Notice for
any reason other than a Prohibitive Event, the Participating Holders shall be
entitled to take any and all remedies hereunder and at law or in equity.

               (b)  If, on or before the Redemption Date, the Company has not
redeemed in full all of the Preferred Shares required to be redeemed by such
date pursuant to Section 10.2(a) because of a Prohibitive Event, the Company
shall issue to each such Participating Holder of Preferred Shares Warrants
immediately exercisable into that number of shares of Class A Common Stock equal
to five percent (5%) of the number of shares of Class A Common Stock to which
such Participating Holder would be entitled if such Participating Holder were to
convert all of the shares of Preferred Shares held by such Holder on the
Redemption Date (after taking into account any Preferred Shares redeemed on such
date) into shares of Class A Common Stock. For every six-month period following
the Redemption Date during which the Company fails to redeem in full all of the
Preferred Shares such Participating Holders required to be redeemed pursuant to
a Demand Notice because of a Prohibitive Event, the Company shall issue
additional Warrants to each such Participating Holder on the final day of such
six-month period, which Warrants shall be immediately exercisable into that
number of shares of Class A Common Stock equal to five percent (5%) of the
number of shares of Class A Common Stock to which such Participating Holder
would be entitled if such Participating Holder were to convert all of its
Preferred Shares held by it on the first day of such six-month period (after
taking into account all redemptions of Preferred Stock on or prior to such date)
into shares of Class A Common Stock on such date.

               (c)  The "as if fully distributed value" (as that term is used in
the definition of Per Share Equity Value) shall be the value determined under
the Fund Securities Purchase Agreement.

               (d)  If the Company fails to redeem any Preferred Stock on the
Redemption Date required to be redeemed pursuant to a Demand Notice, at the
request of the Participating Holders holding a majority of the Preferred Stock
which had been included in such demand but which are still outstanding, the Per
Share Equity Value of the shares of Common Stock (Class A or Class B, as
applicable) into which such shares of Preferred Stock are exercisable shall be
redetermined as of one or more dates after the Redemption Date in accordance
with the definition thereof and Section 10.2(c) until all the shares of
Preferred Stock required to be redeemed are redeemed in full; provided that in
                                                              --------
no event shall the appraisal process set forth in Section 10.2(c) occur more
than once every six months.
