      stock certificates that previously represented and evidenced such
      Outstanding Alamosa Common Shares; and

            B. Alamosa. Holdco, as the holder of the certificate (the

      may, at Holdco's option, surrender the same to the Surviving
      Corporation for cancellation, and Holdco shall be entitled to receive
      from the Surviving Corporation in exchange therefor a certificate
      representing and evidencing the shares of Surviving Corporation

      shall have been converted. Until surrendered, the Holdco Sub Common
      Stock Certificate shall represent and evidence the shares of
      Surviving Corporation Common Stock into which the Outstanding Holdco
      Sub Common Shares theretofore represented and evidenced thereby shall
      have been converted pursuant to Section 2.1 hereof.

            3.2 Holdco Certificate of Incorporation. As of the Effective

shall contain provisions identical to the Alamosa Charter immediately prior
to the Effective Time, which provisions shall, among other things, reflect
the change of Holdco's name to "Alamosa PCS Holdings, Inc."

            3.3 Holdco Bylaws. As of the Effective Time, the bylaws of
Holdco (the "Holdco Bylaws") shall contain provisions identical to the
Alamosa Bylaws immediately prior to the Effective Time. To that end, prior

of the preceding sentence, Holdco shall take all requisite action to cause
the Holdco Bylaws, as the same theretofore may have been amended, altered,
changed and/or supplemented, to be duly amended and restated in accordance
with the DGCL to contain provisions identical to the Alamosa Bylaws
immediately prior to the Effective Time, and as so amended and restated
such Holdco Bylaws shall be and remain the Holdco Bylaws upon and after the
Effective Time, unless and until thereafter duly amended, altered, changed,
repealed and/or supplemented in accordance with the DGCL (which power and
right to amend, alter, change, repeal, and/or supplement, at any time and
from time to time after the Effective Time, are hereby expressly reserved).

            3.4 No Alamosa Stockholder Meeting; Holdco Sub Stockholder
Written Consent. The parties understand and acknowledge that it is
contemplated that the Merger will be effected in accordance with Section
251(g) of the DGCL and that no vote of Alamosa's stockholders adopting,
approving or authorizing this Agreement and the transactions contemplated
hereby, including the Merger, will be required under the DGCL. Holdco, in
its capacity as the sole stockholder of Holdco Sub, as promptly as
practicable on or after the date hereof, shall execute and deliver to
Holdco Sub a written consent in lieu of a stockholder meeting adopting,
approving and authorizing this Agreement and the transactions contemplated
hereby, including the Merger, in accordance with Section 228 of the DGCL.

            3.5 Employee and Director Alamosa Stock Options. Upon and as of
the Effective Time, to the fullest extent permitted by applicable law,
Holdco shall assume all of Alamosa's obligations, and Alamosa shall have no
further obligations, with respect to any then-outstanding option (each, if
any, an "Alamosa Option") to acquire shares of Alamosa Common Stock issued
under any employee or non-employee director stock option plan, agreement
or similar arrangement of Alamosa and the due exercise of rights under any
such Alamosa Option shall entitle the holder thereof to acquire, upon the
same terms and conditions that were applicable under the corresponding
Alamosa Option, a number of shares of Holdco Common Stock identical to the
class and number of shares of Alamosa Common Stock that were subject to
such corresponding Alamosa Option (a "Holdco Option"). Alamosa and Holdco
agree to take all corporate and other action as shall be necessary to
effectuate the foregoing, and Alamosa shall use its best efforts to obtain,
if required, prior to the Closing Date, such consent of each holder of an
Alamosa Option as shall be necessary to effectuate the foregoing. Holdco
shall take all corporate and other action necessary to reserve and make
available for issuance upon the due exercise of rights under the Holdco
Options a sufficient number of shares of Holdco Common Stock, and as soon
as practicable following the Effective Time, shall provide to the record
holders of the Holdco Options appropriate notice of such holder's rights
thereunder.

            3.6 Outstanding Holdco Common Shares. Upon and as of the
Effective Time, Alamosa shall surrender to Holdco the certificate
representing the Outstanding Holdco Common Shares, and the Outstanding
Holdco Common Shares shall be retired as permitted under the DGCL and
resume the status of authorized and unissued shares of Holdco Common Stock.

            3.7 Other Agreements. At the Effective Time, Holdco shall
assume any obligation of Alamosa to deliver or make available shares of
Alamosa Common Stock under any instrument, agreement or employee benefit
plan not referred to in this Section 3 to which Alamosa or any of its
subsidiaries is a party. Any reference to Alamosa Common Stock under any
such instrument, agreement or employee benefit plan shall be deemed to be a
reference to Holdco Common Stock and one share of Holdco Common Stock shall
be issuable in lieu of each share of Alamosa Common Stock required to be
issued by any such instrument, agreement or employee benefit plan, subject
to subsequent adjustment as provided in any such instrument, agreement or
employee benefit plan.

            3.8 Holdco as Successor Registrant to Alamosa. (a) It is the
intent of the parties hereto that Holdco, as of the Effective Time, be
deemed a "successor issuer" for purposes of Rule 12g-3(a) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), so that
Holdco Common Stock shall be deemed registered under Section 12 of the
Exchange Act.

            (b) It is the intent of the parties hereto that Holdco, as of
the Effective Time, be deemed a "successor issuer" for purposes of Rule 414
under the Securities Act of 1933, as amended (the "Securities Act"), so
that Holdco need not file a new registration statement under the Securities
Act for the offering of securities covered by Alamosa's currently effective
registration statement on Form S-8 relating to the registrations of shares
of Alamosa Common Stock that may be issued pursuant to the terms of
Alamosa's 1999 Long Term Incentive Plan.

            3.9 Listing of Holdco Common Stock. Holdco shall use its
reasonable efforts to cause the Holdco Common Stock to be issued and
initially reserved for issuance pursuant to the transactions contemplated
herein to be approved for quotation, upon official notice of issuance, by
The Nasdaq Stock Market, Inc.

            3.10 Filings. At the Effective Time, the Surviving Corporation
shall cause a certified copy of this Agreement to be executed and filed
with the Delaware Secretary of State. At the Effective Time, to the extent
necessary to effectuate the amendments to the Surviving Corporation Charter
and the Holdco Charter contemplated by this Agreement, each of the
Surviving Corporation and Holdco shall cause to be filed with the Delaware
Secretary of State such certificates or documents required to give effect
thereto.

      "Governmental Entity") of competent jurisdiction or other legal
      restraint or prohibition shall be in effect preventing the
      consummation of the Closing.

      Federal income tax purposes as a result of the transactions
      contemplated hereby and that the Merger and the exchange of shares of
      capital stock of Alamosa for shares of capital stock of Holdco shall
      be deemed a transaction described in Section 351(a) and/or 368(a) of
      the Code.

            4.2 Conditions to the Obligations of Alamosa and Holdco Sub to
Effect the Merger. The obligations of Alamosa and Holdco Sub to effect the
Merger shall be subject to the satisfaction of the condition that

of Directors of Holdco Sub, if such Board of Directors shall determine that
for any reason the completion of the transactions provided for herein would
be inadvisable or not in the best interest of such corporation and its
stockholders. In the event of such termination and abandonment, this
Agreement shall become void and neither Alamosa, Holdco, or Holdco Sub nor
their respective stockholders, directors or officers shall have any
liability with respect to such termination and abandonment.
