            AMENDED AND RESTATED AGREEMENT AND PLAN OF REORGANIZATION


         THIS AMENDED AND RESTATED AGREEMENT AND PLAN OF REORGANIZATION (this
"Agreement") is entered into as of July 31, 2000, by and among Alamosa PCS
Holdings, Inc., a Delaware corporation ("Public"), Alamosa Holdings, Inc., a
Delaware corporation ("Superholdings"), Alamosa Sub I, Inc., a Delaware
corporation and wholly-owned direct subsidiary of Superholdings ("Merger Sub"),
and Roberts Wireless Communications, L.L.C., a Missouri limited liability
company ("LLC"), and members of LLC (the "Members").

                                 R E C I T A L S
                                 - - - - - - - -

A.       The Members own, in the aggregate, all of the issued and outstanding
         units of membership interests of LLC, consisting in the aggregate of
         20,000 units (all of the authorized membership interests of LLC,
         whether or not owned by a Member, and any interest received with
         respect to or in exchange for any such interest (including, without
         limitation, units of LLC Holdings), being referred to as "Members'
         Interests"). LLC, LLC Holdings and the Members are sometimes
         collectively referred to herein as the "LLC Parties."

B.       The Board of Managers of LLC deems it advisable and in the best
         interests of its members that LLC and its members form a limited
         liability company to hold all of the Members' Interests of LLC ("LLC
         Holdings"), and that LLC Holdings, merge with and into Superholdings
         (the "Parent Merger") simultaneously with the merger of Merger Sub and
         Public (the "Subsidiary Merger"). The Parent Merger may include the
         merger of any other business entity with which Superholdings has
         agreed to merge, which mergers would take place immediately after the
         merger of LLC Holdings into Superholdings. In furtherance thereof, the
         Board of Directors of Superholdings and the Board of Managers of LLC
         Holdings have approved the Parent Merger, upon the terms and subject
         to the conditions set forth herein. In addition, the Members have
         agreed to vote in favor of the Parent Merger.

C.       The Board of Directors of Public have deemed it advisable and in the
         best interests of its stockholders to enter into the Agreement and Plan
         of Reorganization dated as of July 31, 2000 (the "Subsidiary Merger
         Agreement") by and among Merger Sub, Public and Superholdings and to
         consummate the Subsidiary Merger simultaneously with the consummation
         of the Parent Merger. In furtherance thereof, the Board of Directors of
         Public has approved the Subsidiary Merger Agreement and the Subsidiary
         Merger, upon the terms and subject to the conditions set forth herein.


                                      B-1

<PAGE>   15

D.       Similarly, the Board of Directors of Superholdings have deemed it
         advisable to enter into the Subsidiary Merger Agreement and to
         consummate the Subsidiary Merger simultaneously with the consummation
         of the Parent Merger. In furtherance thereof, the Board of Directors of
         Superholdings has approved the Subsidiary Merger Agreement and the
         Subsidiary Merger, upon the terms and subject to the conditions set
         forth herein.

E.       Further, the Board of Directors of Merger Sub have deemed it advisable
         and in the best interests of its stockholders to enter into the
         Subsidiary Merger Agreement and to consummate the Subsidiary Merger
         simultaneously with the consummation of the Parent Merger. In
         furtherance thereof, the Board of Directors of Merger Sub has approved
         the Subsidiary Merger Agreement and Subsidiary Merger, upon the terms
         and subject to the conditions set forth herein. The Parent Merger, the
         Subsidiary Merger and the other transactions contemplated herein,
         collectively referred to as the "Reorganization," and Sister
         Agreements consummated contemporaneously herewith are part of a single
         reorganization.

F.       As of the date hereof, there are no shares of common stock of
         Superholdings, par value $0.01 per share ("Superholdings Stock"),
         issued and outstanding and as of the date hereof, Superholdings holds
         of record all of the issued and outstanding shares of common stock of
         Merger Sub, par value $0.01 per share ("Merger Sub Stock").

G.       The Board of Directors of Public has determined that in order to
         complete the Parent Merger in a tax-efficient manner, such acquisition
         should be structured as a transaction described in Section 351(a) of
         the Internal Revenue Code of 1986, as amended (the "Code") (all
         citations to the Code, or to the Treasury Regulations promulgated
         thereunder, shall include any amendments or any substitute or
         successor provisions thereto), which will require Public to form a new
         holding company. The parties desire that the Parent Merger, except as
         provided in Sections 1.2(a)(ii) (Cash) and 1.8(b) (Cash Payments)
         herein, qualifies as a transaction described in Section 351(a) of the
         Code.

H.       The parties desire that the Subsidiary Merger qualify as a transaction
         described in Sections 351(a) and 368(a)(1)(A) of the Code by virtue of
         Section 368(a)(2)(E) of the Code. It is contemplated that the
         Subsidiary Merger will be completed substantially simultaneously with
         the merger or consolidation of Superholdings or one or more of its
         subsidiaries with or into one or more business entities (including,
         without limitation, the Parent Merger) in a transaction of the type
         described in Section 351(a) of the Code.

I.       For financial accounting purposes, Public and Superholdings may
         determine that


                                      B-2

<PAGE>   16

         Superholdings' merger with LLC will be accounted for as a pooling of
         interests transaction.

J.       Public, Superholdings, Merger Sub and the LLC Parties acknowledge that
         they have received adequate consideration for entering into, and have
         relied upon the promises, covenants, representations and warranties
         contained in, this Agreement, and that they will be benefitted by the
         transactions contemplated herein.

K.       The LLC Parties have delivered to Superholdings certain disclosure
         schedules of even date herewith referred to herein. Public,
         Superholdings and Merger Sub have delivered to the LLC Parties certain
         disclosure schedules of even date herewith referred to herein. Any
         such disclosure schedules are referred to herein as "Disclosure
         Schedules." The Disclosure Schedules and the Exhibits (herein so
         called) referred to herein are a part of this Agreement.

L.       Public, Superholdings and Merger Sub may enter into other agreements
         (the "Sister Agreements") pursuant to which other business entities
         join in the Parent Merger.

                                A G R E E M E N T
                                - - - - - - - - -

         Based on the recitals set forth above and the representations,
warranties, covenants and agreements contained herein, the parties hereto,
intending to be legally bound, agree as follows:

                                    ARTICLE 1

                                     Mergers
                                     -------

         1.1      The Mergers.

                  (a) The Mergers. Upon the terms and subject to the conditions
set forth in this Agreement:

                           (i) Parent Surviving Corporation. Not later than
August 7, 2000, LLC and its members shall form LLC Holdings, which at such time
shall hold all of the Members' Interests of LLC. At the Effective Time, LLC
Holdings will merge with and into Superholdings in accordance with the terms set
forth herein (one or more other parties, if any, that Public and Superholdings
agree to be constituents in the Parent Merger, pursuant to the terms of a Sister
Agreement may merge into Superholdings immediately following the merger of LLC
Holdings into Superholdings). From and after


                                      B-3

<PAGE>   17


the Effective Time, the separate existence of LLC Holdings and such other
constituents shall cease to exist. Superholdings shall continue as the surviving
corporation in the Parent Merger (the "Parent Surviving Corporation") and shall
continue to be governed by the laws of the State of Delaware. (LLC shall
continue as a subsidiary of Superholdings.)

                           (ii) Subsidiary Surviving Corporation. Simultaneously
with the Parent Merger, Merger Sub will merge with and into Public, in
accordance with the terms set forth herein and the terms of the Subsidiary
Merger Agreement. From and after the Effective Time, the separate corporate
existence of Merger Sub shall cease to exist. Public shall continue as the
surviving corporation in the Subsidiary Merger (the "Subsidiary Surviving
Corporation") and shall continue to be governed by the laws of the State of
Delaware. At the sole discretion of the Board of Directors of Public, as an
alternative structure to the Subsidiary Merger, Public may merge directly with
and into Superholdings, and Superholdings shall continue as the surviving
corporation and shall continue to be governed by the laws of the State of
Delaware.

                  (b) Consummation of the Mergers. The Parent Merger and the
Subsidiary Merger shall be consummated by filing Certificates of Merger (herein
so called) with the secretaries of state of the State of Delaware and State of
Missouri, together with all other documents, notices and filings required by the
Delaware General Corporation Law ("DGCL") and the Missouri Limited Liability
Company Act.

                  (c) Effective Time of the Mergers. The Certificates of Merger
shall provide that the Parent Merger and the Subsidiary Merger shall be
effective as of the date and time set forth in the Certificates of Merger filed
with the Secretary of State of the State of Delaware (the "Effective Time").

                  (d) Effect of the Mergers. At the Effective Time, the effect
of the Parent Merger shall be as provided in Section 264 of the DGCL and other
applicable provisions of the DGCL and Sections 347.700 through 347.735 of the
Missouri Limited Liability Company Act and other applicable provisions of such
act, and the effect of the Subsidiary Merger shall be as provided in Sections
259 and 261 of the DGCL.

                  (e) The Surviving Corporations' Certificates of Incorporation;
Bylaws; Directors and Officers. The certificates of incorporation and bylaws of
Superholdings and Public, in each case as in effect at the Effective Time, shall
be the certificates of incorporation and bylaws of Parent Surviving Corporation
and Subsidiary Surviving Corporation, respectively. At the Effective Time, the
Board of Directors and officers of each of Parent Surviving Corporation and
Subsidiary Surviving Corporation shall be composed of the directors and officers
of Superholdings and Public serving immediately before the Effective Time,
respectively, to hold office until their respective successors are duly elected
or appointed and qualified. The rights and obligations of the current members of
LLC, whether as members of LLC or LLC Holdings, (i) under their respective
operating agreements, limited liability company agreements, or similar


                                      B-4

<PAGE>   18

agreements, including without limitation the obligations to make capital
contributions and (ii) with respect to Members' Interests shall terminate.

         1.2      Terms of the Merger.

                  (a) Consideration for the Parent Merger. Each unit of the
Members' Interests that are units of LLC Holdings (which the members of LLC
shall have received in exchange for their units of LLC) issued and outstanding
immediately prior to the Effective Time shall, at the Effective Time, by virtue
of the Parent Merger and without any action on the part of the holder thereof,
be converted into, as specified by and pursuant to the terms of this Section
1.2(a), into the following:

                           (i) Superholdings Stock. The right to receive a
number of duly authorized, validly issued, fully paid and nonassessable shares
of Superholdings Stock, along with any dividends or distributions thereon after
the Effective Time, equal to the Per Unit LLC Consideration. "Per Unit LLC
Consideration" shall be equal to 675 shares of Superholdings Stock per unit of
the Members' Interests of LLC Holdings; provided, that, the aggregate number of
shares of Superholdings Stock that shall be issued in connection with the Parent
Merger pursuant to this Section 1.2(a) for all of such Members' Interests
outstanding shall be equal to 13,500,000 shares.

                           (ii) Cash. The right to receive cash equal up to
$200.00 per unit of Members' Interests of LLC Holdings, without any interest
thereon (the "Per Unit Cash Consideration"); provided, that, the aggregate
amount of Per Unit Cash Consideration shall be determined pursuant to Section
4.16 (Asset Transfers) and not exceed $4,000,000.

                           (iii) Adjustment of Cash. The amount of Per Unit Cash
Consideration shall be subject to adjustment as provided below and shall be
reduced by the amount of any transfer Taxes owed as a result of the formation of
LLC Holdings or LLC's or LLC Holdings' participation in the Parent Merger,
although no such taxes are anticipated.

                  (b) Right to Withhold.

                           (i) Escrow. At the Closing, Superholdings shall have
the right to withhold from the aggregate amount of the Per Unit LLC
Consideration the amounts of any Interim Losses, as described in further detail
in Section 10.2(d) (Form of Payment; Interim Losses). The aggregate amount of
all such amounts withheld at any time is defined herein as the "Escrow Funds."
An escrow agent (the "Escrow Agent") shall keep the Escrow Funds in a separate
escrow account, maintained on behalf of the Members (the "Escrow Account"),
subject to the terms of the Escrow Agreement (the "Escrow Agreement")
substantially in the form attached as the Exhibit to this Section 1.2(b).

                           (ii) Debt of Members. At the Closing, Public,
Superholdings and


                                      B-5

<PAGE>   19


Merger Sub shall have the right to withhold from the aggregate amount of the Per
Unit Cash Consideration, the amounts, including interest, then owing from the
Members to Public pursuant to any outstanding borrowings.

                  (c) Consideration Subject to Agreements. The consideration to
be paid pursuant to the Parent Merger pursuant to Section 1.2(a) (Consideration
for the Parent Merger) shall be subject to the terms of the Escrow Agreement,
Lock-Up Agreement, and the Indemnity Agreement and, to the extent applicable,
Affiliate Letters. Superholdings shall retain possession of such consideration
until the later of (i) the expiration of the Lock-Up Agreement or (ii) the
resolutions of all claims for Losses that arise pursuant to Section 10.2(a)
(Indemnification of Superholdings), unless the person or entity and, if

consideration shall be delivered or owing in exchange therefor.

                  (i) Rights as Holders. On or after the Effective Time, holders

Public Stock in accordance with the terms of this Agreement shall be deemed,
when paid or issued hereunder, to have been paid or issued, as the case may be,
in full satisfaction of all rights and obligations pertaining to the Members'
Interests or shares theretofore represented by such unit of Members' Interests
or shares of Public Stock.

         1.3      Stock Options.

                  (a) [Intentionally deleted].

                  (b) [Intentionally deleted].

                  (c) [Intentionally deleted].

         1.4      Exchange Agent. Prior to or concurrently with the Effective
Time, Superholdings shall enter into an agreement with such bank or trust
company as may be designated by Superholdings (the "Exchange Agent"), which
shall provide that Superholdings shall deposit with the Exchange Agent as of the
Effective Time, for the benefit of the holders of units of Members' Interests,
for exchange in accordance with this Agreement, through the Exchange Agent, (a)
certificates representing the shares of Superholdings Stock, (b) any dividends
or distributions with respect thereto with a record date after the Effective
Time, (c) any cash payable in lieu of any fractional shares of Superholdings
Stock and (d) the aggregate Per Unit Cash Consideration (collectively, the
"Exchange Fund") issuable pursuant to this Agreement in exchange for outstanding
units of Members' Interests.

         1.5      Exchange Procedure. After the Effective Time, each holder of
Members' Interests shall surrender the certificates representing same or, if the
Members' Interests are not certificated, deliver a release of members' interest,
in a form, duly endorsed or executed as the Parent Surviving Corporation may

to Withhold), 1.2(c) (Consideration Subject to Agreements) and 1.12 (Tax
Withholding), at the time of such surrender or delivery, the merger
consideration applicable to such Members' Interests shall be delivered to such

to have been paid or issued, as the case may be, in full satisfaction of all
rights and obligations pertaining to the surrendered units. No interest shall be


                                      B-7

<PAGE>   21

paid or accrued on any cash payable upon the surrender of any unit of Members'
Interests. If cash payment is to be made, or shares of Superholdings Stock
issued, to a person other than the person who surrendered the units of Members'
Interests, it shall be a condition of payment that the units of Members'
Interests so surrendered shall be properly endorsed or otherwise in proper form
for transfer and that the person requesting such payment shall pay any transfer
or other taxes required by reason of the payment to a person other than the
registered holder of the surrendered units of Members' Interests, or established
to the satisfaction of Superholdings that such taxes have been paid or are not
applicable.

         1.6      Distributions with Respect to Unexchanged Shares. No dividends
or other distributions with respect to Superholdings Stock shall be paid to the
holder of any unsurrendered units of Members' Interests with respect to the
shares of Superholdings Stock issuable upon the surrender of such units of
Members' Interests pursuant to Section 1.5 (Exchange Procedure) and no cash
payment in lieu of fractional shares shall be paid to any such holder pursuant
to Section 1.8 (No Fractional Shares) and all such dividends, other
distributions and cash in lieu of fractional shares of Superholdings Stock shall
be paid by Superholdings to the Exchange Agent and shall be included in the
Exchange Fund, in each case until the surrender of such units of Members'
Interests pursuant to Section 1.5 (Exchange Procedure). Subject to the effect of
applicable escheat or similar laws and subject to Sections 1.2(b) (Right to
Withhold), 1.2(c) (Consideration Subject to Agreements) and 1.12 (Tax
Withholding), following the surrender of any such units of Members' Interests
pursuant to Section 1.5 (Exchange Procedure) there shall be paid to the holder
of the units of Members' Interests, (i) any such dividends or other
distributions, without any interest thereon, which theretofore had become
payable (with a record date or payment date prior to the surrender of units of
Members' Interests) with respect to shares of Superholdings Stock represented by
such units of Members' Interests and (ii) the amount of any cash payable in lieu
of a fractional share of Superholdings Stock to which such holder is entitled
pursuant to Sections 1.8(a) (No Certificates) and 1.8(b) (Cash Payments). No
holder of unsurrendered units of Members' Interests shall be entitled, until the
surrender of such units, to vote the shares of Superholdings Stock into which
the shares of Members' Interests represented thereby shall have been converted.

         1.7      Cancellation and Retirement of Units. As of the Effective
Time, all units of Members' Interests of LLC Holdings issued and outstanding
immediately prior to the Effective Time shall cease to be outstanding and shall
automatically be canceled and retired and shall cease to exist.

         1.8      No Fractional Shares.

                  (a) No Certificates. No certificates representing fractional
shares of Superholdings Stock shall be issued upon the surrender for exchange of
units of Members' Interests which have been converted pursuant to this
Agreement, and such fractional share interests shall not entitle the owner
thereof to vote or to have any rights of a stockholder of Superholdings.

                  (b) Cash Payments. In lieu of any such fractional shares, each
holder of units

                                      B-8

<PAGE>   22

who would otherwise have been entitled to a fraction of a share of Superholdings
Stock upon surrender of units for exchange pursuant to this Article 1 will be
paid an amount in cash (without interest), rounded to the nearest cent,
determined by multiplying (i) the per share closing price on The Nasdaq Stock
Market of Superholdings Stock on the date on which the Effective Time occurs
(or, if Superholdings Stock does not trade on The Nasdaq Stock Market on such
date, the first date of trading of Superholdings Stock on The Nasdaq Stock
Market after the Effective Time) by (ii) the fractional interest to which such
holder otherwise would be entitled. Such amount in cash shall be deemed to be
substituted for any such fractional share and to constitute a portion of the
merger consideration with respect to the related units.

         1.9      Investment of Exchange Fund. The Exchange Agent shall invest
any cash included in the Exchange Fund, as directed by Superholdings, in (a)
direct obligations of the United States of America, (b) obligations for which
the full faith and credit of the United States of America is pledged to provide
for the payment of principal and interest, (c) commercial paper rated the
highest quality by either Moody's Investors Services, Inc. or Standard & Poor's
Corporation, or (d) certificates of deposit, bank repurchase agreements or
bankers' acceptances of commercial banks with capital exceeding $500.0 million.
Any net earnings with respect to the Exchange Fund shall be the property of and
paid over to Superholdings as and when requested by Superholdings.

         1.10     Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the holders of units of Members' Interests for
180 days after the Effective Time shall be delivered to Superholdings, upon
demand, and any holders of units of Members' Interests that have not theretofore
complied with this Article 1 shall thereafter look only to Superholdings, and
only as general creditors thereof, for payment of their claim for any merger
consideration, any cash in lieu of fractional shares of Superholdings Stock and
any dividends or distributions with respect to Superholdings Stock, as provided
herein.

         1.11     No Liability. None of Public, Superholdings, Merger Sub,
Parent Surviving Corporation, Subsidiary Surviving Corporation or the Exchange
Agent shall be liable to any person in respect of any payments or distributions
payable from the Exchange Fund delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law. If any units of Members'
Interests shall not have been surrendered prior to five years after the
Effective Time (or immediately prior to such earlier date on which any merger
consideration in respect of such units of Members' Interests would otherwise
escheat to or become the property of any governmental entity); any amounts
payable in respect of such units of Members' Interests shall, to the extent
permitted by applicable law, become the property of Superholdings, free and
clear of all claims or interest of any person previously entitled thereto.

         1.12     Tax Withholding. Superholdings shall be entitled to deduct and
withhold, or cause to be deducted or withheld, from the consideration otherwise
payable pursuant to this Agreement to any holder of options or units of Members'
Interests such amounts, if any, as are required to be deducted and withheld with
respect to the making of such payment under the Code, or any provision of
applicable state, local or foreign tax law. To the extent that amounts are so
deducted and withheld, such deducted and withheld amounts shall be treated for
all

                                      B-9

<PAGE>   23

purposes of this Agreement as having been paid to such holders in respect of
which such deduction and withholding was made.

"Leases") by LLC of the assets described on the Disclosure Schedule to this
Section, which shall include, among other things, the St. Louis office and
certain of the assets transferred to the Members pursuant to Section 4.16
(Asset Transfers). The Leases shall provide that LLC will pay $1,400 per
month for the initial terms of the Leases for towers within the LLC footprint as
of June 30, 2000, with such tower rents commencing on the Sprint network ready
date, will provide a return based on dollars invested in the switch and retail
locations that is consistent with comparable lease rates within the respective
markets (which will be on a triple-net basis if leases in the market are
triple-net leases) and shall otherwise be on terms reasonably satisfactory to
Superholdings that are similar to other comparable leases to which either Public
or LLC are parties with nonaffiliates; provided, however, that the failure to
enter into the Leases, for any reason, shall not be a breach of this Agreement.

         4.10     Affiliates and Certain Members. If requested by Public, prior
to the Closing Date, LLC shall deliver to Public and Superholdings a letter
identifying all persons who are, at the time the Parent Merger is submitted for
approval to the members of LLC or LLC Holdings, "affiliates" of LLC or LLC
Holdings for purposes of Rule 145 under the Securities Act. If requested by
Public, on or prior to the Closing Date, LLC shall cause each such person to
deliver to Public and Superholdings a written agreement (an "Affiliate Letter").
The certificates representing Superholdings Stock received by such affiliates in
the Parent Merger shall bear a customary legend regarding applicable Securities
Act restrictions.

         4.11     Pooling of Interests. If requested by Public or Superholdings,
the parties shall use their reasonable best efforts to cause the Reorganization
to be accounted for as a pooling of interests under Opinion 16 of the Accounting
Principles Board and applicable SEC rules and regulations, and to cause such
accounting treatment to be accepted by each of the parties' independent
certified public accountants and by the SEC. None of the parties shall knowingly
take any action that would cause such accounting treatment to be unattainable.

         4.12     Employment Agreements. Each party shall use his or its
reasonable best efforts to cause Superholdings or any of its Subsidiaries
and each of Randy Talley and Suzanne Mears to execute and deliver at Closing an
employment agreement (collectively, the "Employment Agreements"), reasonably
acceptable to Superholdings; provided, however, that the failure to enter into
any Employment Agreement, for any reason, shall not be a breach of this
Agreement. The Employment Agreements will provide, among other things, that the
employees will be eligible for compensation, benefits, and stock options under
Superholdings' guidelines and policies, which shall be substantially identical
to Public's guidelines and policies existing on the date hereof for similarly
situated employees. Benefits will include Superholdings' matching of the
employees' contributions under Superholdings' 401(k) plan, if applicable, and
consistent with Superholdings' employment practices. Benefits for each employee
will also include credit for eligibility and vesting purposes for all past
services of such employee with LLC.

         4.13     Consulting Agreements. Superholdings, or Public, as
applicable, and the Members shall use their reasonable best efforts to enter
into, and shall use their reasonable best efforts to cause the Members and
Kay Gabbert ("K.G."). to enter into, five-year consulting agreements
(collectively, the "Consulting Agreements") reasonably acceptable to
Superholdings, or Public, as applicable; provided, however, that the failure to
enter into any Consulting Agreement, for any reason, shall not be a breach
of this Agreement. The Members' Consulting Agreements will be with Public and
will provide, among other things, that the Members will each receive annual
compensation of $125,000, to be paid monthly, and will be reimbursed for
reasonable, approved expenses incurred by them while conducting business for
Superholdings. K.G.'s Consulting Agreement will be with Public and will provide,
among other things, that it will be effective as of July 1, 2000, that she will
receive monthly compensation of $1,000, and that she will receive options for
40,000 shares of Public common stock vesting over five years (beginning with
July 1, 2000) at an exercise price of 90% of the market value of Public common
stock on July 1, 2000. At the Closing, Superholdings shall offer K. G. a
five-year consulting agreement with annual compensation of $100,000 payable
monthly.

         4.14     Reissuance of LLC Audited Financial Statements. The LLC
Parties shall cause LLC's and LLC Holdings' audited financial statements that
are required to be included in the Form S-1 and, if necessary, Form S-4, to
be reissued in accordance with GAAP and in a form reasonably acceptable to
Superholdings.

         4.15     Master Lease Agreement. Superholdings and the Members through
one or more entities controlled by them shall use their reasonable best good
faith efforts to enter into a master lease agreement (the "Master Lease
Agreement") reasonably acceptable to Superholdings providing for the first
right to negotiate tower space leases on a "build-to-suit" basis within

                                      B-25

<PAGE>   39

Superholdings' present and future territory with terms similar to Public's
current leases for towers. The Master Lease Agreement will provide, among other
things, that (i) the Master Lease Agreement will have a five-year term, will not
terminate during that term if Superholdings retains its Sprint PCS affiliation,
and will be subject to five-year extensions if agreed by all parties thereto,
(ii) the Master Lease Agreement will be subject to performance criteria, (iii)
Public is currently a party to contracts for certain tower space and that, to
prevent a violation of existing contracts, new contracts with the Members will
have to be negotiated after the Phase I build-out under the existing contracts
is complete and (iv) the Master Lease Agreement will extend to any acquisitions
by Superholdings. The Master Lease Agreement will also provide that from time to
time as Superholdings determines that it requires additional tower sites, it
will notify Tower Company and provide Tower Company with information concerning
the proposed locations of such sites, the technical requirements and any
available search rings. After Tower Company has been provided with such
information, Superholdings shall grant Tower Company the exclusive right for a
period of 30 days to negotiate with Superholdings for Tower Company to provide
such tower sites. Superholdings agrees that during such 30-day period it will
negotiate with Tower Company in good faith for Tower Company to provide such
tower sites. After such 30 day period, Superholdings may obtain such tower sites
from third parties; provided, that, if Superholdings has not entered into an
agreement to obtain such tower sites within 12 months after such notice to Tower
Company, Superholdings shall again comply with the foregoing notice and
negotiation procedure. Superholdings and the Members shall use their reasonable
best efforts to agree upon the final form of the Master Lease Agreement within
two weeks of the date of this Agreement.

         4.16     Asset Transfers. Prior to the Closing Date, LLC shall transfer
to the Members or, at the election of the Members, Tower Company or other
entities controlled by them the assets listed on the Disclosure Schedule to
this Section 4.16, which shall consist, among other things, of certain real
estate, towers, Nortel base stations, and retail store sites that were funded
directly or indirectly with capital contributions by the Members. The total fair
market value of the assets transferred plus the cash received by the Members
pursuant to Section 1.2 (a)(ii) (Cash) hereof shall not exceed $12,000,000 or
such other amount equal to the Members' actual capital investment that the
parties shall agree upon, and the maximum amount of cash shall not exceed
$4,000,000. If any assets of LLC or LLC Holdings other than those listed on the
Disclosure Schedule to this Section 4.16 are transferred to the members or Tower
Company, then the aggregate cost of such assets shall be deducted from the
amount of cash to be received by the Members pursuant to Section 1.2(a)(ii)
(Cash) hereof.

         Upon execution of this Agreement or as soon thereafter as practicable,
LLC shall submit to Public a proposed fair market value of the transferred
assets. If the parties cannot agree on the fair market value of the transferred
assets within 30 days of the date hereof, then the fair market value will be
determined by an independent third party appraiser selected by Public and
subject to LLC's approval (which approval shall not be unreasonably withheld).
Public shall bear the cost of such appraisal, unless the value determined by the
appraiser is more than 10% greater than the value originally proposed by LLC,
whereupon LLC shall bear such costs.

         4.17 Joint Venture Development Agreement. Superholdings and the Members
or an

                                      B-26

entity controlled by them will use their reasonable best good faith efforts
to enter into a joint venture development agreement (the "Joint Venture
Development Agreement") reasonably acceptable to Superholdings providing for the
formation of international joint ventures on a non-exclusive basis. The Joint
Venture Development Agreement will provide, among other things, that (i) entry
by Superholdings into any specific joint venture will be conditioned upon and
subject to Superholdings' approval of a business plan for the joint venture,
(ii) Superholdings will finance all costs of any joint venture into which it
enters and (iii) each joint venture will be owned 50% by the Members and 50% by
Superholdings, provided that Superholdings will be the manager of the joint
venture.

         4.18     Resale Agreement. Superholdings and its subsidiaries and the
Members or an entity controlled by them will use their reasonable best good
faith efforts to enter into a resale agreement (the "Resale Agreement")
reasonably acceptable to Superholdings and its subsidiaries permitting the
Members or their controlled entities to buy air time at a discount for resale on
a basis no less favorable than any other similar agreement Superholdings may
have; provided, however, that the failure to enter into any Resale Agreement,
for any reason, shall not be a breach of this Agreement.

         4.19     Stock Options. At the Closing Superholdings will cause stock
options to purchase a total of 75,000 shares of Superholdings Common Stock to be
issued to the employees and consultants of LLC listed on a list to be provided
by the Members prior to Closing with an exercise price of 90% of the market
value of Superholdings common stock on the date of grant and other terms as
specified on such list.

Members LLC's FCC F Block licenses, the contract rights LLC has to the
Cause of Action described on the Schedule to this Section 4.20 (the "Cause of

recovered with respect to the Cause of Action and the Proceedings and will
assume all liabilities and obligations with respect to the Cause of Action and
the Proceedings, including the costs and liabilities with respect to any
counterclaims filed with respect to the Cause of Action or the Proceedings.
After the Closing, Superholdings shall cooperate with the Members in the
prosecution of the Cause of Action by making employees available as witnesses
and providing documents, provided that the Members shall bear all expenses
related thereto.

         4.21     Fee for Consent of Senior Lender. If the Closing fails to
occur due to a Breach by one or more of the LLC Parties, then Superholdings,
Public and Merger Sub shall be entitled to receive from the LLC Parties in
addition to any other remedies pursuant to this Agreement, at law or in equity,
an amount equal to the consent fee paid under the Credit Agreement to obtain
consent to the Parent Merger. If the Closing fails to occur due to a Breach by
Superholdings, Public or Merger Sub, then Section 10.2 (e) (Termination Fee)
shall apply. If the Closing fails to occur for any other reason, then each of
the LLC Parties, on one hand, and Superholdings, Public and Merger Sub, on the
other, shall be entitled to receive an amount equal to one half of the consent
fee paid under the Credit Agreement to obtain consent to the Parent Merger.

         4.22     Sprint Payments by Members. The Members shall pay when due all

its respective covenants upon execution of any Related Agreement, in any
respect, except as will not have a Public Material Adverse Change at or after

days, if any, to cure any curable matter that is the subject of a notice under
Section 5.3 (Public and Superholdings Termination Procedure) or Section 5.4
(LLC's Termination Procedure).

                  (e) Prohibition of the Reorganization. By any of Public,
Superholdings or LLC if any federal or state court of competent jurisdiction or
other governmental entity shall have issued an order, decree or ruling, or taken
any other action permanently restraining, enjoining or otherwise prohibiting the

to terminate this Agreement under this Section 5.1 shall not be available to any

notice to the other parties when any of them becomes aware of the occurrence or
failure to occur, or the impending or threatened occurrence or failure to

herein being or becoming untrue or incorrect, (ii) its failure to perform any of
its covenants or agreements contained herein or (iii) any of its Delegated
Conditions, or any condition to the obligation of the parties contained in
Section 3.1 (Joint Conditions), being or becoming impossible to satisfy.

this Agreement or any Related Agreement, then

                                      B-30

<PAGE>   44

the chief financial officer shall deliver a notice to the LLC Parties of
such Breach, specifying the factual basis therefor in reasonable detail.
Furthermore, if Public or Superholdings discovers, by reason of a notice given
pursuant hereto or otherwise, circumstances that would give it the right to
terminate this Agreement pursuant to Section 5.1(b) (By Public or Superholdings)
(other than pursuant to clause (iv) thereof), then Public or Superholdings may
deliver a notice to the LLC Parties of such circumstances, specifying the
factual basis therefor in reasonable detail. The LLC Parties shall have the
right to cure any such matter within 20 business days following the date of
delivery of such notice. If such circumstances create a termination right
pursuant to clauses (i), (ii), or (iii) of Section 5.1(b) (By Public or
Superholdings), then after such notice and the LLC Parties' failure to cure,
either of Public or Superholdings may terminate this Agreement by giving a
notice of termination to the LLC Parties. If the circumstance described in
clause (iv) of Section 5.1(b) (By Public or Superholdings) occurs, Public or
Superholdings may terminate this Agreement by giving written notice of
termination to the LLC Parties.

         5.4      LLC's Termination Procedure. If LLC discovers by reason of a
notice given pursuant hereto or otherwise, circumstances that would give it
the right to terminate this Agreement pursuant to Section 5.1(c) (By LLC), then
LLC shall deliver a notice to Public, Superholdings and Merger Sub of such
circumstances, specifying the factual basis therefor in reasonable detail.
Public, Superholdings and Merger Sub shall have the right to cure any such
matter within 20 business days following the date of delivery of such notice.
Upon such notice and upon Public's, Superholdings' or Merger Sub's failure to
cure, LLC may terminate this Agreement by giving a notice of termination to
Public, Superholdings and Merger Sub.

         5.5      Effect of Termination. Upon termination hereof pursuant to
this Article 5, no party shall have any liability or continuing obligation to
another party arising out of this Agreement, or out of actions taken in
connection herewith, except that Article 10 (Indemnification) and Article 11
(Miscellaneous) shall survive termination hereof. Notwithstanding the foregoing,
termination hereof shall not relieve any party from its liability for (i) the
failure, prior to termination, of such party to perform or comply with its
covenants or agreements or (ii) the representations or warranties made by such
party being untrue or incorrect when made. In addition to the foregoing, (a) if
LLC terminates this Agreement because the issuance of the shares of
Superholdings Stock pursuant to the Parent Merger or the adoption of the
Subsidiary Merger Agreement shall not have been adopted by the holders of the
requisite number of shares of capital stock of Public (including, without
limitation, pursuant to Section 4.4 (Public Stockholders Meeting)) in the manner
required pursuant to Public's certificate of incorporation and bylaws, the DGCL,
or the rules of The Nasdaq Stock Market, as applicable, or other applicable law,
when all other conditions to Closing are satisfied or waived, then Public shall

terminates this Agreement because it was not adopted by the requisite number of
members interests of LLC Holdings (including, without limitation, pursuant to
Section 4.6 (LLC Members Meeting; LLC Holdings)) in the manner required pursuant
to LLC Holdings' organizational documents, the Missouri Limited Liability
Company Act and other applicable law, if such approval is necessary, when all
other conditions to Closing are satisfied or waived, then the LLC Parties shall
pay a

                                      B-31

delivery and performance of this Agreement or the Related Agreements, nor the
consummation of the transactions contemplated hereby or thereby will result in
the creation of any Lien upon any of the properties or assets of any Company or
the Members' Interests. No Member shall have the right to assert dissenters' or
appraisal rights under applicable state law or otherwise have the right to

American Institute of Certified Public Accountants acting through its Accounting
Principles Board or by the Financial Accounting Standards Board or through other
appropriate boards or committees thereof and which are consistently applied for
all periods, so as to properly reflect the financial position, results of
operations and operating cash flow on a consolidated basis of the party, except
that any accounting principle or practice required to be changed by the
Accounting Principles Board or Financial Accounting Standards Board (or other
appropriate board or committee) in order to continue as a generally accepted
accounting principle or practice may be so changed for periods for which such
change is applicable.

                  (b) Capitalization of LLC Holdings. Upon formation, the
Members' Interests

                                      B-36

<PAGE>   50

of LLC Holdings shall consist of 20,000 units. There will be no other equity
interests of LLC Holdings either authorized or outstanding. All of the issued
and outstanding units will be duly authorized and validly issued, fully paid and
nonassessable and free and clear of any preemptive rights. No certificates

be no outstanding preemptive, conversion or other rights, or other options,
warrants or agreements granted by, issued by, or binding upon, LLC Holdings for
the issuance, sale, purchase, repurchase, redemption, acquisition or other
transfer of its equity securities. The Disclosure Schedule to this Section
6.3(b) identifies the holders of all of the Members' Interests of LLC Holdings.
The formation of LLC Holdings and its acquisition of LLC as contemplated hereby
will result in LLC Holdings becoming the sole owner of LLC, holding its interest
in LLC free and clear of Liens other than a pledge under the Credit Agreement.

agreement or understanding (other than this Agreement) relating to the issuance,
sale, redemption, purchase, repurchase, acquisition or other transfer or voting
of any units of Members' Interests or any other equity security of any Company,
other than LLC's operating agreement. There is no plan or intention on the part
of any Member to sell, exchange, transfer or otherwise dispose of any Members'
Interests to be received by such Member. Consummation of the transactions
contemplated by this Agreement will result in Superholdings becoming the sole
owner of LLC Holdings and LLC, holding its interests in LLC Holdings and LLC
free and clear of Liens.

         6.4      Assets.

                  (a)      Personal Property.

interest, free and clear of any Liens, other than Permitted Liens. The

thereunder. All options in favor of such Company to purchase any of the Leased
Premises, if any, are in full force and effect and are described in the
Disclosure Schedule to this Section 6.4(b)(ii). Such Company is in possession of
the Leased Premises and has the right to quiet enjoyment of the Leased Premises

portion of any Real Property or Leased Premises has been condemned, taken

Superholdings, its successors and assigns. All of said utilities are installed

Associate or Affiliate of such Member; no Company has any interest-bearing debt,

and on behalf of any other party. All such Tax Returns were, are and will be

the beneficiary of any extension of time within which to file any Tax Return

or the collection of Taxes.

                           (ii) Additional Taxes. No Company expects any taxing
authority or other governmental unit to assess any additional Taxes. No taxing
authority or other governmental unit has proposed or threatened any assessment,
deficiency, adjustment, dispute or claim concerning any Tax Return or any Tax
liability of any Company. There is no unpaid assessment, deficiency or
adjustment concerning any Tax Return or Tax liability of any Company. To the
Companies' knowledge, none of the Tax Returns of any Company has been selected
for or is now under audit or examination by any taxing authority or other
governmental unit. There are no suits, actions, proceedings or investigations
pending or, to the Companies' knowledge, threatened against any Company with

timely deposited or paid all Taxes required to have been withheld and deposited
or paid in connection with amounts paid or owing to any employee, independent
contractor, creditor, Members or other third party.

be characterized as "excess parachute payments" under Section 280G of the Code.
None of the assets of any Company (A) is property which is required to be
treated as being owned by any other person pursuant to the so-called "safe

or indirectly secures any debt the interest on which is tax exempt under Section

any person under Treasury Regulations Section 1.1502-6 or any similar provision
of state, local, or foreign law, as a member of a consolidated group, transferee
or successor, by contract, or otherwise. No Company has agreed to make, nor is
any Company required to make, any adjustment under Section 481(e) by reason of a
change in accounting method or otherwise. Neither the Members nor any Company is
a person other than a United States person within the meaning of the Code and
the transaction contemplated herein is not subject to the withholding provisions
of Section 3406 of the Code or subchapter A of Chapter 3 of the Code.

                           (v) Unpaid Taxes. The unpaid Taxes of the Companies,
including all Taxes not yet due for any and all periods through the Closing
Date, whether known or unknown, asserted or unasserted (A) do not exceed the
reserve for Tax liability (other than any reserve for deferred Taxes established
to reflect timing differences between book and Tax basis in assets and
liabilities) included in LLC Financial Statements and (B) do not exceed those
reserves as adjusted for the passage of time through the Closing Date.

                             Post-Closing Agreements

         The Members and Superholdings covenant and agree that after the
Closing:

         9.1      Further Actions. Superholdings shall have the right to act in
the name and on the behalf of LLC and LLC Holdings, including, without
limitation, with respect to the execution and performance of such further
instruments of transfer and conveyance, documents and certificates as may be
reasonably requested by Superholdings in order to more effectively convey and
transfer to Superholdings all of the Members' Interests and businesses of LLC,
LLC Holdings and the Subsidiaries, to aid and assist in reducing to possession
or exercising rights with respect to same, or to consummate any of the
transactions contemplated hereby.

         The Members shall as promptly as practical after receipt deliver to
Superholdings any cash, checks, mail, packages, notices and other similar
communications of or to LLC, LLC Holdings or the Subsidiaries that any of them
receives. The Members shall endorse in favor of Superholdings any checks or
other instruments of payment that by their terms are payable to the Members but
that are property of LLC, LLC Holdings or the Subsidiaries.

         9.2      Cooperation. The Members shall use reasonable best efforts to
aid Superholdings in establishing itself as the new owner and operator of the
businesses of LLC, LLC Holdings and the Subsidiaries and, in connection
therewith, shall use reasonable best efforts to maintain LLC's, LLC Holdings'
and the Subsidiaries' goodwill and reputation with all suppliers,

                                      B-61
<PAGE>   75

customers, distributors, creditors and others having business relations with
LLC, LLC Holdings or the Subsidiaries and in the business community generally.
The Members shall cooperate, at Superholdings' expense, and shall cause their
Representatives to cooperate, with Superholdings in connection with
Superholdings' preparation and filing under the Securities Act or Exchange Act
of any registration statement for which the assistance of the LLC Parties or
their respective Representatives is reasonably required.

         9.3      Tax Returns. The Members shall file on behalf of LLC (and, if
necessary, on behalf of any other LLC Party), all tax returns for the fiscal
year ended December 31, 2000, by not later than the unextended due date, and all
tax returns for the short period by not later than the unextended due date and
shall provide copies of such returns to Superholdings immediately after the
filing of such returns.

         9.4      Access to Information; Confidentiality. The Members and
Superholdings shall afford to the other and their respective Representatives
reasonable access to their respective books and records in order to prepare tax
returns within 30 days after the end of the reporting period therefor and other
governmental filings within reasonable time to permit the timely filing thereof.

         9.5      [Intentionally deleted].

         9.6      Name.  After the Closing, M.R. and S.R. shall have the right
to conduct business under the name "Roberts Wireless Communications" and all
derivatives thereof.

         9.7      Tower Payables. The Members shall cause Tower Company to
assume all existing and future tower payables of LLC and LLC Holdings not
otherwise assumed pursuant to Section 8.8 (Tower Payables) and shall cause Tower
Company to inform all vendors to invoice Tower Company for all such tower
payables incurred after June 30, 2000.

         9.8      Reorganization. Following the Closing, Superholdings will not
knowingly take or knowingly permit any of its subsidiaries or Affiliates to take
any action or knowingly fail to take any action that would reasonably cause the
Parent Merger not to qualify as a transaction described in Section 351(a) of the
Code.

         9.9      Insurance. Public and Superholdings acknowledge that LLC's
insurance coverage and health insurance are provided under blanket policies
covering other affiliates of LLC not included in this transaction and that such
coverages will be terminated with respect to LLC and LLC Holdings at Closing.
Accordingly, Superholdings will be responsible for providing replacement
coverage effective at the Closing, provided that LLC's coverages shall apply
with respect to insured events occurring prior to the Closing.

                                 Indemnification

         10.1     Survival; Etc.

                  (a) Contents of this Agreement. The representations,
warranties, covenants and agreements made in Superholdings Closing Certificate,
LLC Parties Closing Certificate, and any Disclosure Schedule shall be deemed
representations, warranties, covenants and agreements made herein.

                  (b) No Effect on Liability. None of (i) the consummation of
the transactions contemplated by this Agreement or the Related Agreements, (ii)
the delay or omission of any party to exercise any of its rights under this
Agreement or any Related Agreement or (iii) any investigation or disclosure that
any party makes, any notice or certificate that any party gives, or any
knowledge that any party obtains as a result thereof, or otherwise, shall (A)
affect the liability of the parties to one another for Breaches of this
Agreement or any Related Agreement or (B) prevent any party from relying on the
representations or warranties contained in this Agreement or any Related
Agreement.

                  As used herein, a party's "Breach" shall mean any
representation or warranty being untrue when made by such party, any breach of
any of such party's covenants or agreements or any other claim that may be
asserted against such party arising from the document in question or the
transactions contemplated thereby.

                  (c) Survival. The representations and warranties of Public,
Superholdings, Merger Sub and the Members made in this Agreement or any Related
Agreement shall survive the Closing, subject to the limitations set forth in
Section 10.1(d) (Commencing Actions). The representations and warranties of LLC,
LLC Holdings and Subsidiaries made herein shall be extinguished at the Closing
and LLC, LLC Holdings and Subsidiaries shall each have no liability thereafter
for Breach hereof. Effective at the Closing, the Members waive and release any
claim for Breach of this Agreement or any Related Agreement by LLC, LLC Holdings
or the Subsidiaries, including without limitation any claim for indemnification
or contribution.

                  (d) Commencing Actions. If the Closing occurs, then any action
against any party hereto for Breaches of this Agreement (other than breaches of
covenants or agreements) occurring on or prior to the time of the Closing that
is not commenced prior to the Closing pursuant to Section 10.7 (Dispute
Resolution) or withheld against pursuant to Section 10.2(d) (Form of Payment;
Interim Losses) shall be deemed waived, and no person shall have any remedy
against any party for any such Breaches; provided, however, (i) if any
Indemnified Party is subject to Losses for Breaches in Sections 6.1(b) (Validity
and Authorization; Power and Authority), 6.3 (Members' Interests), 7.1(b)
(Corporate Power and Authority; Validity and Authorization) or 7.4
(Superholdings Stock) such Indemnified Party may commence an action against the
Indemnifying Party to recover such Losses at any time that such Indemnified
Party is subject to Losses with respect thereto and shall not be barred by the
first clause of this Section and (ii) if any Superholdings Indemnitee is subject
to Losses for Breaches in Section 6.5(b) (Tax Matters), such Superholdings
Indemnitee may commence an action against the Members to

                                      B-63

<PAGE>   77

recover such Losses for one year after the Closing Date and shall not be barred
by the first clause of this Section; provided, further, that any such
Indemnified Party shall use reasonable best efforts to obtain for itself and for
the Indemnifying Party the benefit of any statute of limitations applicable as
against any third party.

                  (e) Materiality. In determining whether (i) a party's
representations and warranties are true and correct in any respect, (ii) a party
has performed any of his, her or its covenants or agreements contained herein or
(iii) a Breach of this Agreement or any Related Agreement has occurred, such
representations, warranties, covenants, agreements and Breaches shall be deemed
to not include any qualification or limitation with respect to materiality
(whether by reference to a "Material Adverse Change," "material adverse effect"
or otherwise). The terms "material," "material adverse effect" and similar terms
(other than Public Material Adverse Change and LLC Material Adverse Change)
shall be construed in the customary manner, but in any event shall mean changes,
effects, events, occurrences, and other matters substantially less in magnitude
than a Public Material Adverse Change in the case of Public, Superholdings or
Merger Sub or an LLC Material Adverse Change in the case of the LLC Parties.

         10.2     Indemnities.

                  (a) Indemnification of Superholdings. Subject to the other
provisions of this Article, before the Closing the LLC Parties jointly and
severally, and after the Closing, the members of LLC Holdings jointly and
severally (collectively, as applicable, the "Member Indemnitors"), shall defend,
indemnify and hold Superholdings and its Affiliates, and their respective
directors, officers, employees, stockholders or members (as the case may be),
agents, advisors, attorneys, accountants, consultants and affiliates
(collectively, the "Superholdings Indemnitees"), harmless from and against, and
promptly reimburse Superholdings Indemnitees for, any loss, expense, damage,
deficiency, liability, claim or obligation, including investigative costs, costs
of defense, settlement costs (subject to approval as provided below) and
attorneys' and accountants' fees (collectively, "Losses") that any Superholdings
Indemnitee suffers or incurs or to which any Superholdings Indemnitee becomes
subject, which Losses arise out of or in connection with (i) any Breach by any
of the LLC Parties of this Agreement, (ii) any claim asserted by any third party
that, assuming the truth thereof, would constitute a Breach by any of the LLC
Parties of this Agreement, (iii) the Cause of Action and all Proceedings or (iv)
all matters listed in the LLC Parties Closing Certificate.

         The amount of the Losses payable by such Member Indemnitors shall bear
interest from the date the Losses are incurred at a rate of interest per annum
that shall, from day to day, equal the lesser of (x) the variable rate of
interest published in the "Money Rates" section of the Wall Street Journal (or
the comparable section of such newspaper) as the prime rate of interest on
corporate loans at large United States money center commercial banks and (y) the
maximum rate allowed under applicable law.

         Each Member Indemnitor agrees that any liability for indemnification (a
"Member Indemnified Claim") under this Section 10.2(a) shall be borne by the
Member Indemnitors jointly and severally regardless of which Member Indemnitor
is required to make any payments

                                      B-64

<PAGE>   78

to a Superholdings Indemnitee for a Member Indemnified Claim pursuant to this
Section 10.2(a). If any Member Indemnitor ("Paying Member Indemnitor") is
required to pay or is held liable for any amount with respect to a Member
Indemnified Claim, each of the other Member Indemnitors (the "Remaining Member
Indemnitors") shall be liable to the Paying Member Indemnitor for, and shall
contribute to and hold the Paying Member Indemnitor harmless from and against,
an amount equal to such Remaining Member Indemnitor's pro rata share of such
liability (based upon the aggregate dollar value of the Per Unit LLC
Consideration and the Per Unit Cash Consideration received by such Remaining
Member Indemnitor pursuant to the Parent Merger), as adjusted to account for a
default by any Member Indemnitor in meeting its obligations hereunder. Such
amount shall be paid within five days of the date any Paying Member Indemnitor
is held liable for, or is required to pay, a Member Indemnified Claim.

                  (b) Indemnification of the Members. Subject to the other
provisions of this Article before the Closing, Public, and after the Closing,
Superholdings, (the "Superholdings Indemnitors") shall defend, indemnify and
hold the Members harmless from and against, and promptly reimburse them for, any
Losses that the Members incur or to which the Members become subject, which
Losses arise out of or in connection with (i) any Breach by Public,
Superholdings or Merger Sub of this Agreement or (ii) any claim asserted by any
third party that, assuming the truth thereof, would constitute a Breach by
Public, Superholdings or Merger Sub of this Agreement.

         The amount of the Losses payable by the Superholdings Indemnitors shall
bear interest from the date the Losses are incurred at a rate of interest per
annum that shall, from day to day, equal the lesser of (x) the variable rate of
interest published in the "Money Rates" section of the Wall Street Journal (or
the comparable section of such newspaper) as the prime rate of interest on
corporate loans at large United States money center commercial banks and (y) the
maximum rate allowed under applicable law.

                  (c) Contribution. If the indemnification provided for in this
Section 10.2 is unavailable to an indemnified party under Sections 10.2(a)
(Indemnification of Superholdings) or 10.2(b) (Indemnification of the Members)
(other than by reason of exceptions provided in this Article 10) in respect of
any Losses, then each applicable indemnifying party, in lieu of indemnifying
such indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such Losses in such proportion as is
appropriate to reflect the relative fault of the LLC Parties (for Losses arising
prior to the Closing) or the Members (for Losses arising after Closing), on the
one hand, and of Public (for Losses arising prior to the Closing) or
Superholdings (for Losses arising after the Closing), on the other hand, in
connection with the Breaches which resulted in such Losses, as well as any other
relevant equitable considerations.

         The LLC Parties, Public and Superholdings agree that it would not be
just and equitable if contribution pursuant to this Section 10.2(c) were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in the
immediately preceding paragraph. Notwithstanding the provisions of this Section
10.2(c), no person guilty of fraudulent misrepresentation shall be entitled to
contribution from

                                      B-65
<PAGE>   79

any person who was not guilty of such fraudulent misrepresentation.

                  (d)      Form of Payment; Interim Losses.

                           (i) Escrow Deposit. Subject to the provisions of this
Section 10.2(d), at the Closing, Superholdings may, after notice to the Members
specifying the factual basis therefor in reasonable detail, collectively
withhold from the aggregate amount of the Per Unit LLC Consideration a number of
shares of Superholdings Stock representing up to $40 million in value (using the
average of the last reported sales prices as reported by The Nasdaq Stock Market
for Public Stock for the 10 days preceding the Closing Date) (the "Escrow
Deposit") to satisfy Losses for which claims of indemnity may have arisen at or
prior to the Closing Date for which Superholdings claims indemnity pursuant to
this Agreement ("Interim Losses").

                           (ii) Interim Loss Value. In order to quantify the
actual value of the Interim Losses, after the Closing a national accounting
firm, independent of the parties hereto and selected by Superholdings, shall
attempt to estimate the amount of Interim Losses (the "Interim Loss Value"). If
such accounting firm is able to reasonably estimate the amount of each claim
comprising the Interim Loss Value, as a fixed amount or as a range of amounts,
then the amount withheld shall equal the estimated fixed amount(s) and/or the
maximum amount of such estimated range(s) of amounts for each claim comprising
the Interim Loss Value. If such accounting firm is unable, for any reason
whatsoever, to reasonably estimate the amount of any claim comprising the
Interim Loss Value, as a fixed amount or as a range of amounts, then
Superholdings shall have no right to withhold any amount with respect to such
claim.

                           (iii) Escrow Adjustment. On the third business day
following the date on which the amount of the Interim Loss Value has been
determined pursuant to Section 10.2(d)(ii)(Interim Loss Value), the difference,
if any, between the Interim Loss Value and the Escrow Deposit (the "Escrow
Adjustment") shall be paid in shares of Superholdings Stock (using the average
of the last reported sales prices as reported by The Nasdaq Stock Market for
Public Stock for the 10 days preceding the Closing Date) as follows:

                                    (A) If the amount of the Interim Loss Value
is less than the Escrow Deposit, then the Escrow Agent shall pay and cause to
be paid to the Members the Escrow Adjustment, as provided in the Escrow
Agreement.

                                    (B) If the amount of the Interim Loss Value
is greater than the Escrow Deposit, then the Members shall pay and cause to be
paid to the Escrow Agent the Escrow Adjustment, as provided in the Escrow
Agreement.

                           (iv) Resolution of Claims. The Escrow Agent shall
hold the Escrow Funds in the Escrow Account until final resolution of the
matters giving rise to the Losses or potential Losses as well as other Losses
that Superholdings subsequently asserts, and then deliver the Escrow Funds in
accordance with such resolution, as provided in the Escrow Agreement.

                                      B-66

<PAGE>   80

After such final resolution, the Escrow Agent shall deliver to Superholdings
the Superholdings Stock, together with any dividends or other distributions with
respect thereto, in satisfaction of any liability in accordance with Section
10.2(d)(v) (Satisfaction of Liability). After the distribution to Superholdings,
the Escrow Agent will release the remaining balance of the Escrow Funds not
subject to further claims to the Members, as provided in the Escrow Agreement.

                           (v) Satisfaction of Liability. After Closing, any
party may satisfy its liability under this Article 10 by (A) delivering shares
of Superholdings Stock valued at the average of the last reported sale prices as
reported by The Nasdaq Stock Market for the 10 days preceding the date of
delivery, together with any dividends or other distributions with respect
thereto or (B) cash payments, at the sole option of such party. If a Member
satisfies its liability by cash payment instead of Superholdings Stock, then the
Escrow Agent shall release to such Member the shares of Superholdings Stock as
determined pursuant to Section 1.2(a)(i) (Superholdings Stock), valued at the
average of the last reported sale prices as reported by The Nasdaq Stock Market
for the 10 days preceding the date of delivery, together with any dividends or
other distributions with respect thereto; provided, however, that Superholdings
and the Members must provide the Escrow Agent with the proper instruments, as
detailed in the Escrow Agreement, as a condition to the Escrow Agent making any
distribution of the Escrow Funds.

                  (e) Termination Fee. If the Closing fails to occur due to a
Breach by Superholdings, Public or Merger Sub, then the LLC Parties shall be
entitled to receive an aggregate of (i) the total amount of management fees paid
to Public under the Services Agreement plus (ii) any consent fee paid to obtain
consent to the Parent Merger under the Credit Agreement in immediately available
funds (the "Termination Fee") from either Superholdings or Public.
Notwithstanding any other provisions of this Agreement, the receipt of the
Termination Fee shall be the sole and exclusive remedy available to the LLC
Parties for any failure of the Closing due to Breach by Superholdings, Public,
or Merger Sub, and the LLC Parties hereby waive their rights to any other
remedies, whether at law or in equity, for such failure caused by such Breach.

         10.3     Limitations on Indemnities.

                  (a)      Basket.

                           (i) Member Indemnitors. Notwithstanding anything to
the contrary in this Article, after the Closing, the Member Indemnitors shall
not have any obligation to indemnify the Superholdings Indemnitees for Losses
arising from a Breach of this Agreement at or prior to the Closing until the
indemnifiable Losses incurred by the Superholdings Indemnitees or to which the
Superholdings Indemnitees become subject, arising from a Breach of this
Agreement at or prior to the Closing, exceed $1.0 million, at which time the
Member Indemnitors shall indemnify the Superholdings Indemnitees pursuant to
this Article 10 for the full amount of the Losses; provided, however, that the
Member Indemnitors shall indemnify the Superholdings Indemnitees for the full
amount of all Losses incurred by the Superholdings Indemnitees related to a
Breach of (i) Section 6.4(a)(iv) hereof (Notes and Accounts Receivable), (ii)
Section 6.5(b) (Tax Matters) related to sales tax on asset purchase transactions
with Sprint or

                                      B-67

<PAGE>   81

its Affiliates, (iii) this Agreement relating to or resulting from the failure
by any Company to perform archaeological studies or surveys with respect to
cellular tower sites without regard to whether such Losses exceed such dollar
amount, or (iv) Section 4.22 (Sprint Payments).

                           (ii) Superholdings Indemnitors. Notwithstanding
anything to the contrary in this Article, the Superholdings Indemnitors shall
not have any obligation to indemnify the Members for Losses arising from a
Breach of this Agreement at or prior to the Closing until the indemnifiable
Losses incurred by the Members or to which the Members become subject, arising
from a Breach of this Agreement at or prior to the Closing, exceed $1.0 million,
at which time the Superholdings Indemnitors shall indemnify the Members pursuant
to this Article 10 for the full amount of the Losses.

                  (b) Cap. After the Closing, no Indemnifying Party shall incur
any liability for Losses pursuant to this Article in excess of the aggregate
dollar value (with appropriate reductions for amounts received by such
Indemnifying Party pursuant to Section 10.2(c) (Contribution)) of the Per Unit
LLC Consideration (with each share of Superholdings Stock valued at the average
of the last reported sale prices of a share of Public Stock as reported by The
Nasdaq Stock Market for the ten (10) days preceding the Closing Date) and the
Per Unit Cash Consideration paid or received, as the case may be, by such
Indemnifying Party pursuant to the Parent Merger; provided however, that no
Member Indemnitor shall have any liability for Losses after he has satisfied
Losses by delivering to Indemnified Parties (i) the number of shares of
Superholdings Stock he received as his aggregate Per Unit LLC Consideration and
(ii) cash in an amount equal to his aggregate Per Unit Cash Consideration.

                  (c) Services Agreement. Notwithstanding anything to the
contrary in this Article 10, the Member Indemnitors shall not have any
obligation to indemnify the Superholdings Indemnitees for Losses to the extent
such Losses have been caused primarily by the actions of Public or any of its
Affiliates under the Services Agreement or by the failure of Public to or any of
its Affiliates take actions under the Services Agreement that would reasonably
be taken in the ordinary course of LLC's business.

                  (d) Damages. Losses recoverable for breach of this Agreement
shall be limited to actual damages, and no party shall recover consequential,
punitive, lost opportunity or special damages of any nature, regardless of the
nature of such party's claim or such party's theory of liability.

                  (e) Exclusivity. In the absence of fraud, the indemnification
provisions of this Article 10 shall be the exclusive remedy for any loss,
expense, damage, deficiency, liability, claim or obligation, including
investigative costs, costs of defense, settlement costs (subject to consent as
provided in Section 10.4(b) (Defense Costs)) and attorneys' and accountants'
fees in connection with this Agreement or any Breach hereof.

                  (f) Indemnification of Escrow Agent. Regarding Section 7
(Indemnification of Escrow Agent) of the Escrow Agreement, (i) the Superholdings
Indemnitors' liability pursuant to Section 7 of the Escrow Agreement shall not
exceed 50% of the aggregate loss, liability or

                                      B-68
<PAGE>   82

expenses incurred by the Escrow Agent and (ii) the Member Indemnitors'
aggregate liability pursuant to Section 7 of the Escrow Agreement shall not
exceed 50% of the aggregate loss, liability or expenses incurred by the Escrow
Agent; provided, that, each Member Indemnitors' liability pursuant to Section 7
of the Escrow Agreement shall not exceed, and shall be in proportion to, the
aggregate dollar value of the Per Unit LLC Consideration (with each share of
Superholdings Stock valued at the average of the last reported sale prices of a
share of Public Stock as reported by The Nasdaq Stock Market for the ten (10)
days preceding the Closing Date) and the Per Unit Cash Consideration received by
such Member Indemnitor pursuant to the Parent Merger.

         10.4     Notice and Opportunity to Defend.

                  (a) Notice, Etc. If any party (the "Indemnified Party")
receives notice of any third-party claim or commencement of any third-party
action or proceeding (an "Asserted Liability") with respect to which any other
party (an "Indemnifying Party") is obligated to provide indemnification pursuant
to Section 10.2(a) (Indemnification of Superholdings ) or Section 10.2(b)
(Indemnification of the Members), the Indemnified Party shall promptly give all
Indemnifying Parties notice thereof. The Indemnified Party's failure so to
notify an Indemnifying Party shall not cause the Indemnified Party to lose its
right to indemnification under this Article 10, except to the extent that such
failure materially prejudices the Indemnifying Party's ability to defend against
an Asserted Liability that such Indemnifying Party has the right to defend
against hereunder (and except as otherwise set forth in this Article 10). Such
notice shall describe the Asserted Liability in reasonable detail, and if
practicable shall indicate the amount (which may be estimated) of the Losses
that have been or may be asserted by the Indemnified Party. Each of the
Indemnifying Parties may defend against an Asserted Liability on behalf of the
Indemnified Party utilizing counsel reasonably acceptable to the Indemnified
Party, unless (i) the Indemnified Party reasonably objects to the assumption of
such defense on the grounds that counsel for such Indemnifying Party cannot
represent both the Indemnified Party and such Indemnifying Party because such
representation would be reasonably likely to result in a conflict of interest or
because there may be defenses available to the Indemnified Party that are not
available to such Indemnifying Party, (ii) such Indemnifying Party is not
capable (by reason of insufficient financial capacity, bankruptcy, receivership,
liquidation, managerial deadlock, managerial neglect or similar events) of
maintaining a reasonable defense of such action or proceeding, or (iii) the
action or proceeding seeks injunctive or other equitable relief against the
Indemnified Party.

                  (b) Defense Costs. If any Indemnifying Party defends an
Asserted Liability, it shall do so at its own expense and shall not be
responsible for the costs of defense, investigative costs, attorney's fees or
other expenses incurred to defend the Asserted Liability (collectively, "Defense
Costs") of the Indemnified Party (which may continue to defend, at its own
expense). Notwithstanding the foregoing, if the person or entity asserting the
Asserted Liability against the Indemnified Party claims or seeks amounts in
excess of the amount set forth in Section 10.3(b) (Cap), then the Indemnifying
Party shall remain liable for the Defense Costs incurred by the Indemnified
Party. If the Indemnified Party assumes the defense of an Asserted Liability by
reason of clauses (i), (ii) or (iii) of subsection (a) above, or because the
Indemnifying Party has

                                      B-69

<PAGE>   83

not elected to assume the defense, then such Indemnifying Party shall indemnify
the Indemnified Party for its Defense Costs; provided, however, the Indemnifying
Parties shall not be liable for the costs of more than one counsel for all
Indemnified Parties in any one jurisdiction. An Indemnifying Party may settle
any Asserted Liability only with the consent of the Indemnified Party, which
consent shall not be unreasonably withheld.

                  (c) Third Party Claims. The parties shall cooperate with each
other with respect to the defense of any claims or litigation made or commenced
by third parties subsequent to the Closing Date arising out of or in connection
with the transactions contemplated by this Agreement or any Related Agreement
and with respect to which indemnification is not available (for any reason)
under this Article 10, provided that the party requesting cooperation shall
reimburse the other party for the other party's reasonable out-of-pocket costs
and expenses of furnishing such cooperation.

         10.5     Delays or Omissions, Etc. Except as provided in Section 10.1
(Survival; Etc.) and Section 10.4(a) (Notice, Etc.), no delay or omission to
exercise any right, power or remedy inuring to any party upon any breach or
default of any party under this Agreement or any Related Agreement shall impair
any such right, power or remedy of such party nor shall it be construed to be a
waiver of any such breach or default, or an acquiescence therein, or of or in
any similar breach or default thereafter occurring; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
theretofore or thereafter occurring. Neither the exercise of nor the failure to
exercise any remedy under this Agreement or any Related Agreement will
constitute an election of remedies or limit in any manner enforcement of any
remedies. All remedies either under this Agreement or any Related Agreement or
by law or otherwise afforded to the parties shall be cumulative and not
alternative.

         10.6     Governing Law; Attorneys' Fees. This Agreement and the Related
Agreements shall be governed by, construed, interpreted and applied in
accordance with the laws of the State of Texas, without giving effect to any
conflict of laws rules that would refer the matter to the laws of another
jurisdiction.

         Subject to Section 10.7 (Dispute Resolution), each party hereto hereby
irrevocably submits to the exclusive jurisdiction of the United States District
Court for the District of Kansas, Kansas City Division and, if such court does
not have jurisdiction, of the courts of the State of Kansas in Wyandotte County,
for the purposes of any action arising out of this Agreement or any of the
Related Agreements, or the subject matter hereof or thereof, brought by any
other party hereto or thereto.

         Subject to Section 10.7 (Dispute Resolution), to the extent permitted
by applicable law, each party hereby waives and agrees not to assert, by way of
motion, as a defense or otherwise in any such action, any claim (i) that it is
not subject to the jurisdiction of the above-named courts, (ii) that the action
is brought in an inconvenient forum, (iii) that it is immune from any legal
process with respect to itself or its property, (iv) that the venue of the suit,
action or proceeding is

                                      B-70
<PAGE>   84

improper or (v) that this Agreement or any Related Agreement, or the subject
matter hereof or thereof, may not be enforced in or by such courts.

         The prevailing party in any action or proceeding relating to this
Agreement or any Related Agreement shall be entitled to recover reasonable
attorneys' fees and other costs from the non-prevailing parties, in addition to
any other relief to which such prevailing party may be entitled.

         10.7     Dispute Resolution.

                  (a) Arbitration. All disputes and controversies of every kind
and nature between the parties hereto arising out of or in connection with this
Agreement (including without limitation this Article 10) or the Related
Agreements as to the construction, validity, interpretation or meaning,
performance, non-performance, enforcement, operation, or breach, shall be
submitted to arbitration pursuant to the following procedures:

                           (i) Notice. After a dispute or controversy arises,
either party may, in a written notice delivered to the other party, demand such
arbitration. Such notice shall designate the name of the arbitrator (who shall
be an impartial person) appointed by the party demanding arbitration, together
with a statement of the matter in controversy.

                           (ii) AAA. Within 30 days after receipt of such
demand, the other party shall, in a written notice delivered to the party
demanding arbitration, name such party's arbitrator (who shall be an impartial
person). If such party fails to name an arbitrator, then the second arbitrator
shall be named by the American Arbitration Association (the "AAA"). The two
arbitrators so selected shall name a third arbitrator (who shall be an impartial
person) within 30 days, or in lieu of such agreement on a third arbitrator by
the two arbitrators so appointed, the third arbitrator shall be appointed by the
AAA. If any arbitrator appointed hereunder shall die, resign, refuse, or become
unable to act before an arbitration decision is rendered, then the vacancy shall
be filled by the methods set forth in this Section 10.7(a)(ii) for the original
appointment of such arbitrator.

                           (iii) Costs. Each party shall bear its own
arbitration costs and expenses. The arbitration hearing shall be held in Kansas
City, Kansas at a location designated by a majority of the arbitrators. The
Commercial Arbitration Rules of the American Arbitration Association shall
govern at such hearing and the substantive laws of the State of Texas (excluding
conflict of laws provisions) shall apply.

                           (iv)     Hearing.  The arbitration hearing shall be
concluded within ten days unless otherwise ordered by the arbitrators and the
written award thereon shall be made within 15 days after the close of submission
of evidence. An award rendered by a majority of the arbitrators appointed
pursuant hereto shall be final and binding on all parties to the proceeding,
shall resolve the question of costs of the arbitrators and all related matters,
and judgment on such award may be entered and enforced by either party in any
court of competent jurisdiction.

<PAGE>   85

                           (v) Complete Defense. Except as set forth in
Section 10.7(b) (Emergency Relief), the parties stipulate that the provisions
of this Section 10.7 shall be a complete defense to any suit, action or
proceeding instituted in any federal, state or local court or before any
administrative tribunal with respect to any controversy or dispute arising out
of this Agreement or any of the Related Agreements. The arbitration provisions
hereof shall, with respect to such controversy or dispute, survive the
termination or expiration of this Agreement or the Related Agreements.

         Except in response to a subpoena or other legal process or disclosure
to professional advisors, lenders and investors, neither any party hereto nor
the arbitrators may disclose the existence or results of any arbitration
hereunder without the prior written consent of the other party; nor will any
party hereto disclose to any third party any confidential information disclosed
by any other party hereto in the course of an arbitration hereunder without the
prior written consent of such other party. Notwithstanding the foregoing, the
parties acknowledge that Public or Superholdings may disclose the existence or
results of an arbitration hereunder, as well as information otherwise required
to be disclosed by deposition, subpoena or other court or governmental action in
connection with Public's or Superholdings' obligations under the Exchange Act
and the rules and regulations promulgated thereunder and in connection with
Public's or Superholdings' registration of offerings of securities under the
Securities Act and the rules and regulations promulgated thereunder, other laws,
regulations or stock exchange requirements.

                  (b) Emergency Relief. Notwithstanding anything in this Section
10.7 to the contrary and subject to the provisions of Section 10.6 (Governing
Law; Attorneys' Fees), either party may seek from a court any provisional remedy
that may be necessary to protect any rights or property of such party pending
the establishment of the arbitral tribunal or its determination of the merits of
the controversy.

                  (c) Definition of Parties. For purposes of this Section 10.7
only, prior to the Closing, the LLC Parties shall be considered one "party" and
Public, Superholdings and Merger Sub shall be considered one "party" and, after
the Closing, the Members shall be considered one "party" and Public,
Superholdings and LLC shall be considered one "party".

                                   ARTICLE 11

                                  Miscellaneous

         11.1 Successors and Assigns. The provisions hereof shall inure to the
benefit of, and be binding upon, the permitted assigns, successors, heirs,
executors and administrators of the parties hereto. This Agreement may not be
assigned without the written consent of Public, Superholdings and the LLC
Parties and any attempted assignment without such consent shall be null and
void; provided, however, each of Public, Superholdings and Merger Sub may assign
any of its rights and obligations hereunder to one of its Affiliates; provided
further, that the LLC Parties may assign their rights to the lenders as
collateral under the Credit Agreement; provided further, that any assignment
hereunder shall not relieve any party of any obligations or liabilities

                                      B-72

hereunder.

         11.2     Entire Agreement. This Agreement (including the Disclosure
Schedules and Exhibits hereto), the other documents delivered pursuant hereto
and referenced herein constitute the full and entire understanding and agreement
between the parties hereto and supersede any other agreement, written or oral,
with regard to the subject matter hereof. This Agreement supersedes those
certain letters dated May 11, 2000, as amended, among certain of the parties
hereto (the "Letters") and hereby supercedes and replaces in its entirety that
certain previous Agreement and Plan of Reorganization by and among Public,
Superholdings, Merger Sub, LLC and Members dated as of July 31, 2000.

         11.3     Amendment. Subject to any applicable provisions of the DGCL,
at any time prior to the Effective Time, the parties hereto may modify or amend
this Agreement by written agreement executed and delivered by duly authorized
officers of the respective parties; provided, however, that after adoption of
this Agreement at the Public Stockholders Meeting, and, if necessary, the
Members Meeting, no amendment shall be made which would reduce the amount or
change the type of consideration into which shares of Public Stock or Members'
Interests shall be converted upon consummation of the Reorganization. This
Agreement may not be modified or amended except by written agreement executed
and delivered by each of the respective parties hereto. Notwithstanding the
foregoing, the merger consideration that the LLC Holdings' members shall receive
can be adjusted if all of the members of LLC Holdings approve of any such
changes.

         11.4     Extension; Waiver. At any time prior to the Effective Time,
the parties may (a) extend the time for the performance of any of the
obligations or other acts of the other parties, (b) waive any inaccuracies in
the representations and warranties of the other parties contained in this
Agreement or in any document delivered pursuant to this Agreement, or (c)
subject to Section 11.3 (Amendment), waive compliance with any of the agreements
or conditions of the other parties contained in this Agreement. Any agreement
on the part of a party to any such extension or waiver shall be valid only if
set forth in a written instrument executed and delivered by a duly authorized
officer on behalf of such party. The failure of any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of such rights.

         11.5     Notices, Etc. All notices and other communications required or
permitted hereunder shall be in writing and shall be sent by certified or
registered mail, postage prepaid with return receipt requested, telecopy (with
hard copy delivered by overnight courier service), or delivered by hand,
messenger or overnight courier service, and shall be deemed given when received
at the addresses or telecopy numbers of the parties set forth below, or at such
other address or telecopy number furnished in writing to the other parties

the availability of, nor any limit on, any remedy hereunder limits the remedies
of any party hereto against third parties.

be invalid, illegal or unenforceable, such provision shall be reformed to best
effectuate the intent of the parties and permit enforcement hereof, and the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby. If such provision is not capable of
reformation, it shall be severed from this Agreement and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

         11.8     Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one and the same instrument. Any counterpart may be delivered

<PAGE>   88

convenience of reference only and are not to be considered in construing this
Agreement. References to "Articles" and "Sections" herein are references to
articles and sections of this Agreement, respectively. The words "herein,"
"hereof," "hereto" and "hereunder" and other words of similar import refer to
this Agreement as a whole and not to any particular Article, Section or other
subdivision.

         11.10    Confidentiality.

                  (a) Confidential Information. As used herein, "Confidential
Information" means confidential business information regarding any party hereto
or its Affiliates, including, without limitation, marketing lists used by LLC or
any information identifying the source of, and the process used by LLC to
obtain, such marketing lists; customer lists and files; prices and costs;
business and financial records; information relating to personnel contracts;
stock ownership; liabilities; litigation and the terms of this Agreement or any
Related Agreement and any written analysis or other document reflecting such
information that a party hereto prepared (an "Analysis"). For purposes of this
Section 11.10, the party or parties disclosing Confidential Information are
referred to collectively as the "Disclosing Party" and the party or parties
receiving Confidential Information are referred to collectively as the
"Receiving Party." However, "Confidential Information" shall not include:

                           (i) any information properly obtained and already in
the possession of the Receiving Party, prior to the execution of the letter
agreement, dated May 11, 2000, as amended, or information available to the
Receiving Party from public records or from other sources in accordance with
law,

                           (ii) any information that is in the public domain or
subsequently enters the public domain otherwise than through disclosure by the
Receiving Party or any of the Receiving Party's Representatives,

                           (iii) any information that is independently developed
by or on behalf of the Receiving Party without reference to the Confidential
Information,

                           (iv) any information that is acquired from a person
(other than Public, Superholdings, Merger Sub or the LLC Parties) not known by
the Receiving Party to be providing such information in breach of a
confidentiality obligation, or

                           (v) information the release of which has been
approved in writing by the Disclosing Party;

provided, that, further information received by Public, Superholdings or Merger
Sub shall cease to be Confidential Information after the Closing.

                  (b) Disclosure. The LLC Parties, on the one hand, and Public,
Superholdings, and Merger Sub, collectively on the other, will treat the
Confidential Information disclosed by the other as confidential, will use the
Confidential Information only in connection with their

                                      B-75

<PAGE>   89

evaluation of the transactions hereunder, and will not disclose it to others,
except that each party shall have the right to communicate the information to
any of such party's Representatives; provided, that, such Representative is
informed that the Confidential Information is confidential and such
Representative agrees to be bound by the terms of this Section 11.10. The
parties shall be liable for any breach of this Section 11.10 by any of their
Representatives.

         The parties acknowledge that Public and Superholdings may disclose
Confidential Information in connection with Public's and Superholdings'
obligations under the Exchange Act and the rules and regulations promulgated
thereunder, and in connection with Public's and Superholdings' registration of
offerings of securities under the Securities Act, and the rules and regulations
promulgated thereunder; provided, however, that prior to any such disclosure of
Confidential Information, Public or Superholdings shall provide LLC with the
opportunity to review and comment, if practicable, upon the disclosure. Any such
disclosures of Confidential Information by Public or Superholdings shall not be
a breach or violation of this Section 11.10.

         Each of the LLC Parties acknowledge that (a) it is aware that the
United States securities laws prohibit any person who has material, nonpublic
information about a company from purchasing or selling securities of that
company, or from communicating that information to any other person under
circumstances in which it is reasonably foreseeable that such person is likely
to purchase or sell those securities and (b) it is familiar with the Exchange
Act and the rules and regulations promulgated thereunder, and agrees that it
will neither use, nor cause any third party to use, any Confidential Information
in contravention of the Exchange Act or any such rules and regulations,
including Rules 10b-5 and 14e-3.

         If any Receiving Party becomes legally compelled by deposition,
subpoena or other court or governmental action to disclose any of the
Confidential Information, then such Receiving Party will give the Disclosing
Party prompt notice to that effect, and will cooperate with the Disclosing Party
if the Disclosing Party seeks to obtain a protective order concerning the
Confidential Information. The Receiving Party will disclose only such
Confidential Information as its counsel shall advise is legally required.

         The parties acknowledge that remedies at law may be inadequate to
protect against breach of this Section 11.10. Each party hereby agrees in
advance to the granting of injunctive relief in the non-breaching party's or
parties' favor without proof of actual damages as a remedy for breach of this
Section 11.10.

         Upon termination of this Agreement pursuant to the provisions of
Article 5 (Termination), the Receiving Party will, at the Disclosing Party's
request, return to the Disclosing Party or destroy all originals, copies,
extracts or other reproductions of the Confidential Information that the
Disclosing Party provides, and destroy any Analysis.

         11.11    Expenses. Except as otherwise expressly provided herein, each
party hereto will bear its respective expenses (third-party or otherwise)
incurred in connection with the preparation, execution and performance of this
Agreement, the Related Agreements and the transactions contemplated herein or
therein, including without limitation all fees and expenses of

                                      B-76

<PAGE>   90

agents, representatives, counsel and accountants. The LLC Parties shall not
utilize assets of LLC to pay such expenses. Notwithstanding the foregoing, LLC
may pay up to $400,000 for the expenses it incurs in connection with this
Agreement for its accountants, attorneys, and fairness opinions plus any filing
fees of the LLC Parties required under the HSR Act.

         11.12    Responsibility for Superholdings and Merger Sub. Public shall
be directly responsible for assuring that Superholdings and Merger Sub perform
all of their obligations hereunder.

         11.13    Knowledge. Statements herein based on the knowledge of LLC or
LLC Holdings or words of similar import shall mean only the actual knowledge
after due inquiry of S.R., M.R. or K.G.

                     Form of Opinion of LLC Parties' Counsel

1. Each of the Companies is a limited liability company duly organized and
validly existing under the laws of the State of Missouri. Each of the Companies
has all requisite power and authority to own, lease and operate all properties
and assets owned or leased by it and to conduct its business as previously and
currently conducted by it. Each of the Companies is qualified to do business in
each jurisdiction in which it is required to be so qualified, except where the
lack of such qualification would not have a material adverse effect on such
Company.

2. Each of the Companies has full power and authority to consummate the Parent
Merger and to execute, deliver and perform the Agreement, the Related Agreements
and the other instruments called for therein to which it is a party.

3. The Agreement and the Related Agreements have been duly authorized, executed
and delivered by each of the Companies and, upon obtaining the Members Required
Vote, will constitute (or, in the case of Related Agreements or instruments
called for by the Agreement or the Related Agreements, to be executed by such
Company at or before the Closing, upon execution will constitute) the legal,
valid and binding obligation of such Company, enforceable against such Company
in accordance with their terms.

4. Each of the Members has full requisite power and authority (or if a natural
person, capacity) to execute, deliver and perform the Agreement, the Related
Agreements and the other instruments called for therein to which such Member is
a party. The Agreement, the Related Agreements and the other instruments called
for therein to which such Member is a party have been duly executed and
delivered by each of the Members and constitute (or, in the case of Related
Agreements or instruments called for in the Agreement, to be executed by the
Member at or before the Closing, will constitute) the legal, valid and binding
obligation of the Member, enforceable against the Member in accordance with
their terms.

5. Each of the Companies is the holder of record of all of the issued and
outstanding shares of capital stock or interests, as appropriate, of its
Subsidiaries free and clear of any Liens.

6. The Members' Interests of LLC consist of 20,000 units and no preferred units.
There are no other equity interests of LLC either authorized or outstanding. All
of the issued and outstanding units have been duly authorized and validly
issued, are fully paid and nonassessable and are free and clear of any
preemptive rights. No certificates have been issued to represent the Members'
Interests in LLC. There are no outstanding preemptive, conversion or other
rights, or other options, warrants or agreements granted by, issued by, or
binding upon, LLC for the issuance, sale, purchase, repurchase, redemption,
acquisition or other transfer of its equity securities.



                                      B-87
<PAGE>   101

7. Each Member is the holder of record of the units set forth in the Agreement.
To our knowledge, no Member is a party to any contract, agreement or
understanding (other than the Agreement) relating to the issuance, sale,
redemption, purchase, repurchase, acquisition or other transfer or voting of any
units of Members' Interests or any other equity security of any Company, other
than LLC's operating agreement.

8. The Members' Interests of LLC Holdings consists of 20,000 units and no
preferred units. There are no other equity interests of LLC Holdings either
authorized or outstanding pursuant to LLC's certificate of formation or
organizational agreements. All of the issued and outstanding units are duly
authorized and validly issued, fully paid and nonassessable and free and clear
of any preemptive rights. No certificates were issued to represent the Members'
Interests in LLC Holdings. There are no outstanding preemptive, conversion or
other rights, or other options, warrants or agreements granted by, issued by, or
binding upon, LLC Holdings for the issuance, sale, purchase, repurchase,
redemption, acquisition or other transfer of its equity securities pursuant to
LLC's certificate of formation or organizational agreements.

9. The formation of LLC Holdings transferred all of the Members' Interests of
LLC to LLC Holdings free and clear of Liens. Consummation of the transactions
contemplated by the Agreement will transfer to Superholdings all of the Members'
Interests of LLC Holdings free and clear of Liens.

10. The transactions contemplated by the Agreement do not conflict with any
provisions of the Contracts (as such term is defined in Section 6.4(d)(i)
(Definition) of the Agreement), except as listed on the exhibit hereto. Except
as specified on the Disclosure Schedule to Section 6.1(e) (LLC Parties Consents
Required), the transactions contemplated by the Agreement do not require any
consents. Notwithstanding the foregoing, the consents of Sprint, DLJ and Lucent
are sufficient such that the Sprint, DLJ and Lucent contracts do not otherwise
conflict with the transactions contemplated by the Agreement.

11. To our knowledge, there are no Proceedings or Orders.

12. No state takeover statute is applicable to any Company in connection with
the Agreement, the Parent Merger or the other transactions contemplated thereby.

                                MEMBER AGREEMENT

         This Member Agreement (the "Member Agreement") is delivered pursuant to
Sections 1.2(c) (Consideration Subject to Agreements), 2.4(b)(i) (Lock-Up
Agreement), 2.4(b)(ii) (Indemnity Agreement) 2.4(b)(iii) (Members' Releases) and
10.2 (Indemnities) of that certain Agreement and Plan of Reorganization (the

Holdings, Inc., a Delaware corporation ("Public"), Alamosa Holdings, Inc., a
Delaware corporation ("Superholdings"), Alamosa Sub I, Inc., a Delaware
corporation and wholly-owned direct subsidiary of Superholdings ("Merger Sub"),
and Roberts Wireless Communications, L.L.C., a Missouri limited liability
company ("LLC"), and members of LLC (the "Members"). All capitalized terms used
herein and not otherwise defined in this Certificate will have the meanings
assigned to them in the Agreement. The parties hereto agree as follows:

         1. Lock-Up. Each of the undersigned hereby covenants to Public and
Superholdings that before September 30, 2001, the undersigned will not, without
the prior written consent of Superholdings, offer, sell, contract to sell,
pledge or otherwise dispose of, (or enter into any transaction which is designed
to, or might reasonably be expected to, result in the disposition (whether by
actual disposition or effective economic disposition due to cash settlement or
otherwise) of the undersigned's holdings of Superholdings Stock) or establish or
increase a put equivalent position or liquidate or decrease a call equivalent
position within the meaning of Section 16 of the Securities Exchange Act of
1934, as amended, and the rules and regulations of the Securities and Exchange
Commission promulgated thereunder, with respect to any Superholdings Stock, or
any securities convertible into, or exercisable or exchangeable for,
Superholdings Stock, or publicly announce an intention to effect any such
transaction, other than (a) shares of Superholdings Stock disposed of as bona
fide gifts to persons who also enter into lock-up agreements in the form hereof
and (b) shares of Superholdings Stock acquired other than pursuant to the
Reorganization. This Section 1 of this Member Agreement is the "Lock-Up
Agreement" referred to in the Agreement.

          2. Registration Provisions.

         (a) Certain Information. The undersigned Member hereby covenants to
provide to Public and Superholdings the information required by the Form S-1, as
provided by Section 4.2(c) (Form S-1) of the Agreement, as is reasonably
requested by Public or Superholdings as soon as possible, but no later than five
business days after the date of such request. In addition, the undersigned
Member hereby covenants that none of the information supplied or to be supplied
by the undersigned Member specifically for inclusion in the Form S-1 will, at
the time the Form S-1 is filed with the SEC, at any time that such form is
amended or supplemented and at the time it becomes effective or remains in
effect under the Securities Act, contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading. Notwithstanding the foregoing, if
the undersigned Member becomes aware, at any time, of any untrue statement of a
material fact or omission of any material fact required to be stated in the Form
S-1 (or other appropriate



                                     B-94
<PAGE>   108

registration statement form), then the undersigned Member shall promptly notify
Public and Superholdings of such untrue statement, pursuant to Section 11.5
(Notices, Etc.) of the Agreement.

         (b) Blackout. The undersigned member hereby agrees that if
Superholdings furnishes to the undersigned member a notice signed by the
President of Superholdings stating that Superholdings has determined in good
faith that it would be seriously detrimental to Superholdings and its
stockholders for the Form S-1 to be filed (or remain in effect) and it is
therefore essential to defer the filing of such Form S-1 (or temporarily suspend
the effectiveness of such registration statement or use of the related
prospectus) (a "Blackout Notice"), then Superholdings shall have the right (i)
immediately to defer such filing for a period of not more than sixty (60) days
beyond the date by which such Form S-1 was otherwise planned to be filed or (ii)
suspend such effectiveness for a period of not more than sixty (60) days (any
such deferral or suspension period of up to sixty (60) days, a "Blackout
Period"). The undersigned member agrees to cease any disposition during such
Blackout Period of the Superholdings Stock received by the undersigned member in
connection with the Reorganization. Superholdings may not utilize any of its
rights under this Section 2 of this Member Agreement to defer the filing of the
Form S-1 (or suspend the effectiveness of the Form S-1) more than twice in any
twelve (12) month period.

         3. Indemnity. Each of the undersigned hereby agrees to be bound by all
of the provisions of Article 10 of the Agreement (Indemnification), and the
direct and indirect owners of the undersigned's Members' Interests (who are
signatories below) shall also be so bound to the extent that they receive any
merger consideration or proceeds thereof. This Section 2 of this Member
Agreement is the "Indemnity Agreement" referred to in the Agreement.

         4. Intent to Sell. The undersigned hereby agrees that it has no plan or
intention to sell, exchange, transfer or otherwise dispose of any of the
Superholdings Stock received by such undersigned member in connection with the
Reorganization.

         5. Releases. Superholdings hereby releases on its own behalf any and
all claims held or to be held by Superholdings against LLC, LLC Holdings, and
their successors, assigns, officers, directors, employees and agents, after the
Closing. Each of the undersigned hereby releases any and all claims held or to
be held by the undersigned member against LLC, LLC Holdings, and their
successors, assigns, officers, directors, employees and agents, but excluding
any claims each of the undersigned may have to unpaid compensation and benefits.
Each of the undersigned hereby agrees to be released from any obligation under
the operating agreements of LLC or LLC Holdings. This Section 5 of this Member
Agreement is the "Members Releases" referred to in the Agreement.

         6. Consideration. Each of the undersigned hereby acknowledges that the
consideration received by him pursuant to the Agreement represents the amount of
consideration he is entitled to receive under the operating agreements of LLC
and LLC Holdings and satisfies



                                     B-95

in full any and all claims held or to be held by him with respect to his
membership interests in LLC and LLC Holdings.
