1.       General Information

         (a) Alamosa (Delaware), Inc. ("Alamosa Delaware" or the "Corporation")
             is a Delaware corporation.

         (b) Alamosa (Delaware), Inc. was organized under the laws of the State
             of Delaware.

2.       Securities Act Exemption Applicable

         The Corporation and Alamosa Holdings, Inc. ("Alamosa") are offering
(the "Exchange Offers") to exchange: (i) $650 principal amount of the
Corporation's 11% Senior Notes due 2010 (the "New Senior Notes") pursuant to the
New Senior Notes Indenture (the "New Senior Notes Indenture") and one (1) unit
(a "Unit," each such Unit to consist of one (1) share of Series B Convertible
Preferred Stock of Alamosa and 73.61 Contingent Value Rights ("CVRs," as more
fully defined herein)) for each $1,000 principal amount of 12.5% Senior Notes
due 2011 (CUSIP No. 011588ABC) and 13.625% Senior Notes due 2011 (CUSIP No.
011588AD2) issued by the Corporation and guaranteed by Alamosa (collectively,
the "Senior Notes") (holders of Senior Notes who tender their securities for
exchange will also receive cash, at the time of distribution of the New Notes
and the Units, in an amount equal to any accrued and unpaid interest on the
Senior Notes) and (ii) $650 original issue amount of Alamosa Delaware's 12.0%
Senior Discount Notes due 2009 (the "New Senior Discount Notes," together with
the New Senior Notes the "New Notes") pursuant to the New Senior Discount Notes
Indenture (the "Senior Discount Notes Indenture," and together with the New

Soliciting Acceptances of a Prepackaged Plan of Reorganization, dated September
12, 2003 (the "Disclosure Statement"), and in related documents incorporated by

         As the New Notes are proposed to be offered for exchange by the
Corporation with its existing security holders exclusively and solely for
outstanding securities of the Corporation, the transaction is exempt from
registration under the Securities Act of 1933, as amended (the "Securities
Act"), pursuant to the provisions of Section 3(a)(9) thereof. No sales of
securities of the same class as the New Notes have been or are to be made by the
Corporation by or through an underwriter at or about the same time as the
Exchange Offers for which the exemption is claimed. No consideration has been,
or is to be given, directly or indirectly, to any person in connection with the
transaction, except for the customary payments to be made in respect of
preparation, printing, and mailing of the Disclosure Statement and related
documents and the engagement of Wells Fargo Bank Minnesota, N.A. as Exchange
Agent and Information Agent for the Corporation. No holder of the outstanding
securities has made or will be requested to make any cash payment to the
Corporation in connection with the Exchange Offers.
