                            11% Senior Note due 2010

1.  Interest

     Alamosa (Delaware), Inc., a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount of this
Security at the rate per annum shown above. The Company will pay interest
semiannually on January 31 and July 31 of each year, commencing January 31,
2004. Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the rate borne by the Securities to the extent
lawful.

2.  Method of Payment

     The Company will pay interest on the Securities (except defaulted interest)
to the Persons who are registered holders of Securities at the close of business
on January 15 or July 15 next preceding the interest payment date even if
Securities are canceled after the record date and on or before the interest
payment date. Holders must surrender Securities to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States of America that at the time of payment is legal tender for payment
of public and private debts. Payments in respect of the Securities represented
by a Global Security (including principal, premium and interest) will be made by
wire transfer of immediately available funds to the accounts specified by The
Depository Trust Company. The Company will make all payments in respect of a
Definitive Security (including principal, premium and interest), by mailing a
check to the registered address of each Holder thereof; provided, however, that
payments on the Securities may also be made, in the case of a Holder of at least
$1,000,000 aggregate principal amount of Securities, by wire transfer to a U.S.
dollar account maintained by the payee with a bank in the United States if such
Holder elects payment by wire transfer by giving written notice to the Trustee
or the Paying Agent to such effect designating such account no later than 30
days immediately preceding the relevant due date for payment (or such other date
as the Trustee may accept in its discretion).

<PAGE>

3.  Paying Agent and Registrar

     Initially, Wells Fargo Bank Minnesota, N.A., a national banking association
(the "Trustee"), will act as Paying Agent and Registrar. The Company may appoint
and change any Paying Agent, Registrar or co-registrar without notice. The
Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar or co-registrar.

4.  Indenture

     The Company issued the Securities under an Indenture dated as of November
10, 2003 (the "Indenture"), among the Company, the Subsidiary Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. [SS SS] 77aaa-77bbbb) as in effect on the date of the Indenture
(the "TIA"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the TIA for a
statement of those terms.

     The Securities are senior unsecured obligations of the Company limited to
$260.0 million aggregate principal amount (subject to Section 2.07 of the
Indenture). The Indenture imposes certain limitations on the ability of the
Company and its Restricted Subsidiaries to, among other things, make certain
Investments and other Restricted Payments, pay dividends and other
distributions, incur Debt, enter into consensual restrictions upon the payment
of certain dividends and distributions by such Restricted Subsidiaries, issue or
sell shares of Capital Stock of such Restricted Subsidiaries, enter into or
permit certain transactions with Affiliates, create or incur Liens and make
Asset Sales. The Indenture also imposes limitations on the ability of the
Company and the Subsidiary Guarantors to consolidate or merge with or into any
other Person or sell, transfer, assign, lease, convey or otherwise dispose of
all or substantially all of the Property of the Company or any such Subsidiary
Guarantor.

     Pursuant to the terms of the Indenture, the Subsidiary Guarantors have,
jointly and severally, guaranteed the due and punctual payment of the principal
and interest on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture. The Subsidiary Guaranties are
subordinated in right of

                                        2
<PAGE>

payment to each Subsidiary Guarantor's obligations with respect to Designated
Senior Debt.

5.  Optional Redemption

     Except as set forth below, the Securities are not redeemable prior to July
31, 2007. On and after that date, the Company may redeem the Securities in whole
at any time or in part from time to time at the following redemption prices
(expressed in percentages of principal amount), plus accrued and unpaid
interest, if any, to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
interest payment date that is on or prior to the date of redemption), if
redeemed during the 12-month period beginning on or after July 31 of the years
set forth below:

                                                                  Redemption
Period                                                            Price
------                                                            -----
2007...............................................................105.500%
2008...............................................................102.750%
2009...............................................................101.375%
2010 and thereafter................................................100.000%

     Notwithstanding the foregoing, on or prior to July 31, 2007 the Company may
redeem up to 35% of the original aggregate principal amount of the Securities
issued with the proceeds from one or more Public Equity Offerings, at a
redemption price equal to 111.00% of the principal amount thereof, plus accrued
and unpaid interest thereon, if any, to the redemption date (subject to the
right of Holders of record on the relevant record date to receive interest due
on the relevant interest payment date that is on or prior to the date of
redemption); provided, however, that after giving effect to any such redemption,
at least 65% of the original aggregate principal amount of the Securities
remains outstanding. Any such redemption shall be made within 90 days of such
Public Equity Offering upon not less than 30 nor more than 60 days' prior
notice.

6.  Sinking Fund

     The Securities are not subject to any sinking fund.

                                        3
<PAGE>

7.  Notice of Redemption

     Notice of redemption will be mailed by first-class mail at least 30 days
but not more than 60 days before the redemption date to each Holder of
Securities to be redeemed at his or her registered address. Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

8.  Repurchase of Securities at the Option of Holders upon Change of Control

     Upon a Change of Control, any Holder of Securities will have the right,
subject to certain conditions specified in the Indenture, to cause the Company
to repurchase all or any part of the Securities of such Holder at a purchase
price equal to 101% of the principal amount of the Securities to be repurchased
plus accrued and unpaid interest, if any, to the date of purchase (subject to
the right of Holders of record on the relevant record date to receive interest
due on the relevant interest payment date that is on or prior to the date of
purchase) as provided in, and subject to the terms of, the Indenture.

9.  Denominations; Transfer; Exchange

     The Securities are in registered form without coupons in denominations of
$1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar or any co-registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements or transfer documents and to pay any
taxes required by law or permitted by the Indenture. The Registrar or
co-registrar need not register the transfer of or exchange any Securities
selected for redemption (except, in the case of a Security to be redeemed in
part, the portion of the Security not to be redeemed) or to transfer or exchange
any Securities for a period of 15 days prior to a selection of Securities to be
redeemed or 15 days before an interest payment date.

                                        4
<PAGE>

10.  Persons Deemed Owners

     The registered Holder of this Security may be treated as the owner of it
for all purposes.

11.  Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for two
years, the Trustee or Paying Agent shall pay the money back to the Company at
its written request unless an abandoned property law designates another Person.
After any such payment, Holders entitled to the money must look only to the
Company and not to the Trustee for payment.

12.  Discharge and Defeasance

     Subject to certain conditions, the Company at any time may terminate some
of or all its obligations under the Securities and the Indenture if the Company
deposits with the Trustee money or U.S. Government Obligations for the payment
of principal, premium, if any, and interest on the Securities to redemption or
maturity, as the case may be.

13.  Amendment, Waiver

     Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended without prior notice to any
Securityholder but with the written consent of the Holders of at least a
majority in aggregate principal amount of the outstanding Securities, and (ii)
any default or noncompliance with any provision may be waived with the written
consent of the Holders of at least a majority in principal amount of the
outstanding Securities. Subject to certain exceptions set forth in the
Indenture, without the consent of any Holder of Securities, the Company and the
Trustee may amend the Indenture or the Securities (i) to cure any ambiguity,
omission, defect or inconsistency; (ii) to comply with Article V of the
Indenture; (iii) to provide for uncertificated Securities in addition to or in
place of certificated Securities; (iv) to make certain changes in the
subordination provisions; (v) to add Guarantees with respect to the Securities
or to release Subsidiary Guarantors from Subsidiary Guaranties as provided in
the Indenture; (vi) to secure the Securities; (vii) to add additional covenants
or to surrender rights and powers conferred on the Company; (viii) to comply
with the requirements of the U.S. Securities and Exchange Commission in order to
effect or maintain the qualification of the Indenture under the TIA; or (ix) to
make any change

                                       5
<PAGE>

that does not adversely affect the rights of any Securityholder.

14.  Defaults and Remedies

     If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate principal amount of the Securities then out
standing, subject to certain limitations, may declare all the Securities to be
immediately due and payable. Certain events of bankruptcy or insolvency are
Events of Default and shall result in the Securities being immediately due and
payable upon the occurrence of such Events of Default without any further act of
the Trustee or any Holder.

     Holders of Securities may not enforce the Indenture or the Securities
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in aggregate principal
amount of the Securities then outstanding may direct the Trustee in its exercise
of any trust or power under the Indenture. The Holders of a majority in
aggregate principal amount of the Securities then outstanding, by written notice
to the Company and the Trustee, may rescind any declaration of acceleration and
its consequences if the rescission would not conflict with any judgment or
decree, and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of the
acceleration.

15.  Trustee Dealings with the Company

     Subject to certain limitations imposed by the TIA, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

16.  No Recourse Against Others

     A director, officer, employee or stockholder, as such, of the Company or
any Subsidiary Guarantor shall not have any liability for any obligations of the
Company or any Subsidiary Guarantor under the Securities or the Indenture or for
any claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives and releases all
such liability. The waiver and release are part of the consideration for the
issue of the Securities.

                                        6
<PAGE>

17.  Authentication

     This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

18.  Abbreviations

     Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

19.  Governing Law

     THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK.

20.  CUSIP Numbers

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption, and reliance may be placed only on the
other identification numbers placed thereon.

     THE COMPANY WILL FURNISH TO ANY HOLDER OF SECURITIES UPON WRITTEN REQUEST
AND WITHOUT CHARGE TO THE HOLDER A COPY OF THE INDENTURE WHICH HAS IN IT THE
TEXT OF THIS SECURITY. REQUESTS MAY BE MADE TO:

                        12% Senior Discount Note due 2009

1.  Interest

     Alamosa (Delaware), Inc., a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount at
maturity of this Security at the rate per annum shown above. The Company will
pay interest semiannually on January 31 and July 31 of each year, commencing
January 31, 2006. The Securities will not accrue cash interest on or prior to
July 31, 2005. Interest shall be computed on the basis of a 360-day year of

2.  Method of Payment

     The Company will pay interest on the Securities (except defaulted interest)

made, in the case of a Holder of at least $1,000,000 aggregate principal amount
at maturity of Securities, by wire transfer to a U.S. dollar account maintained
by the payee with a bank in the United States if such Holder elects payment by
wire transfer by giving written notice to the Trustee or the Paying Agent to
such effect designating such account no later than 30 days immedi-

ately preceding the relevant due date for payment (or such other date as the
Trustee may accept in its discretion).

3.  Paying Agent and Registrar

     Initially, Wells Fargo Bank Minnesota, N.A., a national banking association
(the "Trustee"), will act as Paying Agent and Registrar. The Company may appoint
and change any Paying Agent, Registrar or co-registrar without notice. The
Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar or co-registrar.

4.  Indenture

     The Company issued the Securities under an Indenture dated as of November
10, 2003 (the "Indenture"), among the Company, the Subsidiary Guarantors and
the Trustee. The terms of the Securities include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture
(the "TIA"). Terms defined in the Indenture and not defined herein have the
meanings ascribed thereto in the Indenture. The Securities are subject to all
such terms, and Securityholders are referred to the Indenture and the TIA for a
statement of those terms.

     The Securities are senior unsecured obligations of the Company limited to
$237,689,000 aggregate principal amount at maturity (subject to Section 2.07 of
the Indenture). The Indenture imposes certain limitations on the ability of the
Company and its Restricted Subsidiaries to, among other things, make certain
Investments and other Restricted Payments, pay dividends and other
distributions, incur Debt, enter into consensual restrictions upon the payment
of certain dividends and distributions by such Restricted Subsidiaries, issue or
sell shares of Capital Stock of such Restricted Subsidiaries, enter into or
permit certain transactions with Affiliates, create or incur Liens and make
Asset Sales. The Indenture also imposes limitations on the ability of the
Company and the Subsidiary Guarantors to consolidate or merge with or into any
other Person or sell, transfer, assign, lease, convey or otherwise dispose of
all or substantially all of the Property of the Company or any such Subsidiary
Guarantor.

     Pursuant to the terms of the Indenture, the Subsidiary Guarantors have,
jointly and severally, guaranteed the due and punctual payment of the Accreted
Value and interest on the Securities and all other amounts payable by the
Company

                                        2
<PAGE>

under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture. The Subsidiary Guaranties are
subordinated in right of payment to each Subsidiary Guarantor's obligations with
respect to Designated Senior Debt.

5.  Optional Redemption

     Except as set forth below, the Securities are not redeemable prior to July
31, 2006. On and after that date, the Company may redeem the Securities in whole
at any time or in part from time to time at the following redemption prices
(expressed in percentages of Accreted Value), plus accrued and unpaid interest,
if any, to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date that is on or prior to the date of redemption), if redeemed during the
12-month period beginning on or after July 31 of the years set forth below:

Period                                                           Redemption
------                                                              Price
                                                                    -----

2006.............................................................106.000%
2007.............................................................103.000%
2008.............................................................101.500%
2009 and thereafter..............................................100.00%

     Notwithstanding the foregoing, on or prior to July 31, 2006 the Company may
redeem up to 35% of the original aggregate principal amount at maturity of the
Securities issued with the proceeds from one or more Public Equity Offerings, at
a redemption price equal to 112.00% of the Accreted Value thereof, plus accrued
and unpaid interest thereon, if any, to the redemption date (subject to the
right of Holders of record on the relevant record date to receive interest due
on the relevant interest payment date that is on or prior to the date of
redemption); provided, however, that after giving effect to any such redemption,
at least 65% of the original aggregate principal amount at maturity of the
Securities remains out standing. Any such redemption shall be made within 90
days of such Public Equity Offering, upon not less than 30 nor more than 60
days' prior notice.

6. Sinking Fund

     The Securities are not subject to any sinking fund.

                                        3
<PAGE>

7.  Notice of Redemption

     Notice of redemption will be mailed by first-class mail at least 30 days
but not more than 60 days before the redemption date to each Holder of
Securities to be redeemed at his or her registered address. Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000. If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date interest
ceases to accrue on such Securities (or such portions thereof) called for
redemption.

8.  Repurchase of Securities at the Option of Holders upon Change of Control

     Upon a Change of Control, any Holder of Securities will have the right,
subject to certain conditions specified in the Indenture, to cause the Company
to repurchase all or any part of the Securities of such Holder at a purchase
price equal to 101% of the Accreted Value of the Securities to be repurchased
plus accrued and unpaid interest, if any, to the date of purchase (subject to
the right of Holders of record on the relevant record date to receive interest
due on the relevant interest payment date that is on or prior to the date of
purchase) as provided in, and subject to the terms of, the Indenture.

9.  Denominations; Transfer; Exchange

     The Securities are in registered form without coupons in denominations of
$1,000 and whole multiples of $1,000. A Holder may transfer or exchange
Securities in accordance with the Indenture. Upon any transfer or exchange, the
Registrar or any co-registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements or transfer documents and to pay any
taxes required by law or permitted by the Indenture. The Registrar or
co-registrar need not register the transfer of or exchange any Securities
selected for redemption (except, in the case of a Security to be redeemed in
part, the portion of the Security not to be redeemed) or to transfer or exchange
any Securities for a period of 15 days prior to a selection of Securities to be
redeemed or 15 days before an interest payment date.

10.  Persons Deemed Owners

     The registered Holder of this Security may be treated as the owner of it
for all purposes.

11.  Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for two
years, the Trustee or Paying Agent shall pay the money back to the Company at
its written request unless an abandoned property law designates another Person.
After any such payment, Holders entitled to the money must look only to the
Company and not to the Trustee for payment.

12.  Discharge and Defeasance

     Subject to certain conditions, the Company at any time may terminate some
of or all its obligations under the Securities and the Indenture if the Company
deposits with the Trustee money or U.S. Government Obligations for the payment
of Accreted Value of, premium, if any, and interest on the Securities to
redemption or maturity, as the case may be.

13.  Amendment, Waiver

     Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended without prior notice to any
Securityholder but with the written consent of the Holders of at least a
majority in aggregate principal amount at maturity of the outstanding
Securities, and (ii) any default or noncompliance with any provision may be
waived with the written consent of the Holders of at least a majority in
principal amount at maturity of the outstanding Securities. Subject to certain
exceptions set forth in the Indenture, without the consent of any Holder of
Securities, the Company and the Trustee may amend the Indenture or the
Securities (i) to cure any ambiguity, omission, defect or inconsistency; (ii) to
comply with Article V of the Indenture; (iii) to provide for uncertificated
Securities in addition to or in place of certificated Securities; (iv) to make
certain changes in the subordination provisions; (v) to add Guarantees with
respect to the Securities or to release Subsidiary Guarantors from Subsidiary
Guaranties as provided in the Indenture; (vi) to secure the Securities; (vii) to
add additional covenants or to surrender rights and powers conferred on the
Company; (viii) to comply with the requirements of the U.S. Securities and
Exchange Commission in order to effect or maintain the qualification of the
Indenture under the

                                       5
<PAGE>

TIA; or (ix) to make any change that does not adversely affect the rights of any
Securityholder.

14.  Defaults and Remedies

     If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate principal amount at maturity of the Securities then
outstanding, subject to certain limitations, may declare all the Securities to
be immediately due and payable. Certain events of bankruptcy or insolvency are
Events of Default and shall result in the Securities being immediately due and
payable upon the occurrence of such Events of Default without any further act of
the Trustee or any Holder.

     Holders of Securities may not enforce the Indenture or the Securities
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in aggregate principal
amount at maturity of the Securities then outstanding may direct the Trustee in
its exercise of any trust or power under the Indenture. The Holders of a
majority in aggregate principal amount at maturity of the Securities then
outstanding, by written notice to the Company and the Trustee, may rescind any
declaration of acceleration and its consequences if the rescission would not
conflict with any judgment or decree, and if all existing Events of Default have
been cured or waived except nonpayment of Accreted Value or interest that has
become due solely because of the acceleration.

15.  Trustee Dealings with the Company

     Subject to certain limitations imposed by the TIA, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

16.  No Recourse Against Others

     A director, officer, employee or stockholder, as such, of the Company or
any Subsidiary Guarantor shall not have any liability for any obligations of the
Company or any Subsidiary Guarantor under the Securities or the Indenture or for
any claim based on, in respect of or by reason of such obligations or their
creation. By accepting a Security, each Securityholder waives and releases all
such liability.

                                        6
<PAGE>

The waiver and release are part of the consideration for the issue of the
Securities.

17.  Authentication

     This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

18.  Abbreviations

     Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TENENT (tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

19.  Governing Law

     THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK.

20.  CUSIP Numbers

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption, and reliance may be placed only on the
other identification numbers placed thereon.

     THE COMPANY WILL FURNISH TO ANY HOLDER OF SECURITIES UPON WRITTEN REQUEST
AND WITHOUT CHARGE TO THE HOLDER A COPY OF THE INDENTURE WHICH HAS IN IT THE
TEXT OF THIS SECURITY. REQUESTS MAY BE MADE TO:
