                                   ARTICLE II

                                 The Securities

         SECTION 2.01. Form and Dating. Provisions relating to the Securities
are set forth in Appendix A, which is hereby incorporated in and expressly made
part of this Indenture. The Securities and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit 1 to Appendix A,
which is hereby incorporated in and expressly made a part of this Indenture. The
Securities may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Company is subject, if any, or usage,
provided that any such notation, legend or endorsement is in a form reasonably
acceptable to the Company. Each Security shall be dated the date of its

                                       25

<PAGE>

authentication. The terms of the Securities set forth in Exhibit 1 to Appendix A
are part of the terms of this Indenture.

         SECTION 2.02. Execution and Authentication. Two Officers shall sign the
Securities for the Company by manual or facsimile signature. The Company's seal
shall be impressed, affixed, imprinted or reproduced on the Securities and may
be in facsimile form.

         If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a written order of the Company in
the form of an Officers' Certificate for the authentication and delivery of such
Securities, and the Trustee in accordance with such written order of the Company
shall authenticate and deliver such Securities.

         A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

         The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate the Securities. Unless limited by the terms of
such appointment, an authenticating agent may authenticate Securities whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as any Registrar, Paying Agent or agent for service of notices and
demands.

         SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an
office or agency where Securities may be presented for registration of transfer
or for exchange (the "Registrar") and an office or agency where Securities may
be presented for payment (the "Paying Agent"). The Registrar shall keep a
register of the Securities and of their transfer and exchange. The Company may
have one or more co-registrars and one or more additional paying agents. The
term "Paying Agent" includes any additional paying agent.

         The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar, co-registrar or transfer agent.

         The Company initially appoints the Trustee as Registrar and Paying
Agent in connection with the Securities.

         SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to each due
date of the principal, premium, if any, and interest on any Security, the
Company shall deposit with the Paying Agent a sum sufficient to pay such
principal, premium, if any, and interest when so becoming due. The Company shall
require each Paying Agent (other than the Trustee) to agree in writing that the
Paying Agent shall hold in trust for the benefit of Securityholders or the
Trustee all money held by the Paying Agent for the

                                       26
<PAGE>

payment of principal, premium, if any, and interest on the Securities and shall
notify the Trustee of any default by the Company in making any such payment. If
the Company or a Wholly Owned Subsidiary acts as Paying Agent, it shall
segregate the money held by it as Paying Agent and hold it as a separate trust
fund. The Company at any time may require a Paying Agent to pay all money held
by it to the Trustee and to account for any funds disbursed by the Paying Agent.
Upon complying with this Section 2.04, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

         SECTION 2.05. Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall furnish to the Trustee, in writing at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders.

         SECTION 2.06. Replacement Securities. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that such
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies
any other reasonable requirements of the Trustee. If required by the Trustee or
the Company, such Holder shall furnish an indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss that any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.

         Every replacement Security is an additional obligation of the Company.

         SECTION 2.07. Outstanding Securities. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancellation and those described in this
Section as not outstanding. A Security does not cease to be outstanding because
the Company or an Affiliate of the Company holds the Security.

         If a Security is replaced pursuant to Section 2.06, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

         If the Paying Agent segregates and holds in trust, in accordance with
this Indenture, on a redemption date or maturity date money sufficient to pay
all principal, premium, if any, and interest payable on that date with respect
to the Securities (or portions thereof) to be redeemed or maturing, as the case
may be, then on and after that date such Securities (or portions thereof) cease
to be outstanding and interest on them ceases to accrete.

         SECTION 2.08. Temporary Securities. Until definitive Securities are
ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities and
deliver them in exchange for temporary Securities.

         SECTION 2.09. Cancellation. The Company at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall

                                       27

<PAGE>

forward to the Trustee any Securities surrendered to them for registration of
transfer, exchange or payment. The Trustee and no one else shall cancel and
destroy (subject to the record retention requirements of the Exchange Act) all
Securities surrendered for registration of transfer, exchange, payment or
cancellation and deliver a certificate of such destruction to the Company. The
Company may not issue new Securities to replace Securities it has redeemed, paid
or delivered to the Trustee for cancellation.

         SECTION 2.10. Defaulted Interest. If the Company defaults in a payment
of interest on the Securities, the Company shall pay the defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date
and the amount of defaulted interest to be paid.

         SECTION 2.11. CUSIP Numbers. The Company in issuing the Securities may
use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Holders; provided,
however, that neither the Company nor the Trustee shall have any responsibility
for any defect in the "CUSIP" number that appears on any Security, check, advice
of payment or redemption notice, and any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.

                                   ARTICLE III

                                   Redemption

         SECTION 3.01. Notices to Trustee. If the Company elects to redeem
Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and that such redemption is being made pursuant to paragraph 5 of
the Securities.

         The Company shall give each notice to the Trustee provided for in this
Section 3.01 at least 45 days before the redemption date unless the Trustee
consents to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the conditions herein.

         SECTION 3.02. Selection of Securities To Be Redeemed. If fewer than all
the Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed pro rata or by lot or a method that complies with applicable legal and
securities exchange requirements, if any, and that the Trustee considers fair
and appropriate and in accordance with methods generally used at the time of
selection by fiduciaries in similar circumstances. The Trustee shall make the
selection from outstanding Securities not previously called for redemption.
Securities the Trustee selects shall be in amounts of $1,000 or a whole multiple
of $1,000. The Trustee shall notify the Company promptly of the Securities to be
redeemed.

                                       28
<PAGE>

         SECTION 3.03. Notice of Redemption. At least 30 days but not more than
60 days before a redemption date of Securities, the Company shall mail a notice
of redemption by first-class mail to each Holder of Securities to be redeemed.

         The notice shall identify the Securities to be redeemed and shall
state:

         (1) the redemption date;

         (2) the redemption price;

         (3) the name and address of the Paying Agent;

         (4) that Securities called for redemption must be surrendered to the
    Paying Agent to collect the redemption price;

         (5) if fewer than all the outstanding Securities are to be redeemed,
    the identification of the particular Securities to be redeemed;

         (6) that, unless the Company defaults in making such redemption
    payment, interest on Securities (or portion thereof) called for redemption
    ceases to accrete on and after the redemption date; and

         (7) that no representation is made as to the correctness or accuracy of
    the CUSIP number, if any, listed in such notice or printed on the
    Securities.

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section at least 45 days before the redemption date.

         SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption
is mailed, Securities called for redemption become due and payable on the
redemption date and at the redemption price stated in the notice. Upon surrender
to the Paying Agent, such Securities shall be paid at the redemption price
stated in the notice, plus accrued interest to the redemption date (subject to
the right of Holders of record on the relevant record date to receive interest
due on the related interest payment date that is on or prior to such redemption
date). Failure to give notice or any defect in the notice to any Holder shall
not affect the validity of the notice to any other Holder.

         SECTION 3.05. Deposit of Redemption Price. Prior to the redemption
date, the Company shall deposit with the Paying Agent (or, if the Company or a
Wholly Owned Subsidiary is the Paying Agent, shall segregate and hold in trust)
money sufficient to pay the redemption price of and accrued interest (subject to
the right of Holders of record on the relevant record date to receive interest
due on the related interest payment date that is on or prior to the date of
redemption) on all Securities to be redeemed on that date other than Securities
or portions of Securities called for redemption that have been delivered by the
Company to the Trustee for cancellation.

         SECTION 3.06. Securities Redeemed in Part. Upon surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate for the Holder (at the Company's expense) a new Security equal in
principal amount to the unredeemed portion of the Security surrendered.

                                       29

specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the rate borne by the Securities to the extent

    Subsidiary Guarantor is the obligor on such Debt and the payee is not the
    Company or a Subsidiary Guarantor, such Debt must be expressly subordinated
    to the prior payment in full in cash of all obligations then due with
    respect to the Securities, in the case of the Company, or Subsidiary
    Guarantee, in the case of a Subsidiary Guarantor, and (ii) any subsequent
    issue or transfer of Capital Stock or other event that results in any such
    Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
    subsequent transfer of any such Debt (except to the Company or another
    Restricted Subsidiary) shall be deemed, in each case, to constitute the
    Incurrence of such Debt by the issuer thereof;

         (e) Debt under Interest Rate Agreements entered into by the Company or
    a Restricted Subsidiary for the purpose of limiting interest rate risk in
    the ordinary course of the financial management of the Company or such
    Restricted Subsidiary and not for speculative purposes, provided, however,
    that the obligations under such agreements are related to payment
    obligations on Debt otherwise permitted by the terms of this Section 4.03;

         (f) Debt in connection with one or more standby letters of credit or
    performance bonds issued by the Company or a Restricted Subsidiary in the
    ordinary course of business or pursuant to self-insurance obligations and
    not in connection with the borrowing of money or the obtaining of advances
    or credit;

         (g) Debt outstanding on the Issue Date not otherwise described in
    clauses (a) through (f) above;

         (h) Permitted Refinancing Debt Incurred in respect of Debt Incurred
    pursuant to clause (1) of the first paragraph of this Section 4.03 or clause
    (a), (c) or (g) above or clause (j) below;

         (i) additional Debt of the Company in an aggregate principal amount
    outstanding at any one time not to exceed $75.0 million; and

         (j) Acquired Debt Incurred by a Subsidiary Guarantor at the time a
    Sprint PCS Affiliate is merged with or into or becomes a Subsidiary of or
    transfers all or substantially all of its assets to such Subsidiary
    Guarantor on or prior to January 1,

                                       31

<PAGE>

    2005, but only to the extent that immediately after giving effect to the
    Incurrence of such Debt (i) the Leverage Ratio would not exceed 7.75 to 1.0;
    and (ii) the Leverage Ratio immediately following such Incurrence would
    decrease as compared to the Leverage Ratio immediately prior to such
    Incurrence.

         For purposes of determining compliance with this Section 4.03,

         (a) in the event that any Debt is allowed to be Incurred pursuant to
    more than one of the categories of Debt described above, including clause
    (1) of the first paragraph of this Section 4.03 or as Permitted Debt, the
    Company, in its sole discretion, will classify such Debt, as of the time of
    Incurrence thereof, as Debt incurred pursuant to a particular clause under
    the first paragraph of this Section 4.03, and if Incurred as Permitted Debt
    will specify under which clause of Permitted Debt the Debt is Incurred; and

         (b) Debt may be divided and classified in more than one of the
    categories of Debt described above.

         Notwithstanding anything to the contrary contained in this Section
    4.03,

         (a) the Company shall not, and shall not permit any Subsidiary
    Guarantor to, Incur any Debt pursuant to this Section 4.03 if the proceeds
    thereof are used, directly or indirectly, to Refinance any Subordinated
    Obligations unless such Debt shall be subordinated to the Securities or the
    applicable Subsidiary Guaranty, as the case may be, to at least the same
    extent as such Subordinated Obligations, and

         (b) the Company shall not permit any Restricted Subsidiary that is not
    a Subsidiary Guarantor to Incur any Debt pursuant to this Section 4.03 if
    the proceeds thereof are used, directly or indirectly, to Refinance any Debt
    of the Company or any Subsidiary Guarantor.

         SECTION 4.04. Limitation on Restricted Payments. The Company shall not
make, and shall not permit any Restricted Subsidiary to make, directly or
indirectly, any Restricted Payment if at the time of, and after giving effect
to, such proposed Restricted Payment,

         (a) a Default or Event of Default shall have occurred and be
    continuing,

         (b) the Company could not Incur at least $1.00 of additional Debt
    pursuant to clause (1) of the first paragraph of Section 4.03, or

         (c) the aggregate amount of such Restricted Payment and all other
    Restricted Payments declared or made since the Issue Date (the amount of any
    Restricted Payment, if made other than in cash, to be based upon Fair Market
    Value) would exceed an amount equal to the sum of:

              (1) the result of:

                   (A) Cumulative EBITDA, minus

                   (B) the product of 1.5 and Cumulative Interest Expense, plus

              (2) Capital Stock Sale Proceeds, plus

                                       32

<PAGE>

              (3) the aggregate net cash proceeds received by the Company or any
         Restricted Subsidiary from the issuance or sale after the Issue Date of
         convertible or exchangeable Debt that has been converted into or
         exchanged for Capital Stock (other than Disqualified Stock) of the
         Company or any direct or indirect parent holding company of the
         Company, excluding (x) any such Debt issued or sold to the Company or a
         Subsidiary of the Company or an employee stock ownership plan or trust
         established by the Company or any such Subsidiary for the benefit of
         their employees, and (y) the aggregate amount of any cash or other
         Property distributed by the Company or any Restricted Subsidiary upon
         any such conversion or exchange,

              plus

              (4) an amount equal to the sum of:

                   (A) the net reduction in Investments in any Person other than
              the Company or a Restricted Subsidiary resulting from dividends,
              repayments of loans or advances or other transfers of Property, in
              each case to the Company or any Restricted Subsidiary from such
              Person, less the cost of the disposition of such Investment, plus

                   (B) the portion (proportionate to the Company's equity
              interest in such Unrestricted Subsidiary) of the Fair Market Value
              of the net assets of an Unrestricted Subsidiary at the time such
              Unrestricted Subsidiary is designated a Restricted Subsidiary;

provided, however, that the sum in this clause (4) shall not exceed, in the case
of any Person, the amount of Investments previously made (and treated as a
Restricted Payment) by the Company or any Restricted Subsidiary in such Person.

         Notwithstanding the foregoing limitation, the Company may take any
action if it is in compliance with any of the following clauses (a) through (h):

         (a) pay dividends on its Capital Stock within 60 days of the
    declaration thereof if, on such declaration date, such dividends could have
    been paid in compliance with this Indenture; provided, however, that at the
    time of such payment of such dividend, no other Default or Event of Default
    shall have occurred and be continuing (or result therefrom); provided
    further, however, that such dividend shall be included in the calculation of
    the amount of Restricted Payments;

         (b) purchase, repurchase, redeem, legally defease, acquire or retire
    for value Capital Stock of the Company or Subordinated Obligations in
    exchange for, or out of the proceeds of the substantially concurrent sale
    of, Capital Stock of the Company (other than Disqualified Stock and other
    than Capital Stock issued or sold to a Subsidiary of the Company or an
    employee stock ownership plan or trust established by the Company or any
    such Subsidiary for the benefit of their employees); provided, however,
    that:

              (1) such purchase, repurchase, redemption, legal defeasance,
         acquisition or retirement shall be excluded in the calculation of the
         amount of Restricted Payments, and

                                       33

<PAGE>

              (2) the Capital Stock Sale Proceeds from such exchange or sale
         shall be excluded from the calculation pursuant to clause (c)(2) above;

         (c) purchase, repurchase, redeem, legally defease, acquire or retire
    for value any Subordinated Obligations in exchange for, or out of the
    proceeds of the substantially concurrent sale of, Permitted Refinancing
    Debt; provided, however, that such purchase, repurchase, redemption, legal
    defeasance, acquisition or retirement shall be excluded in the calculation
    of the amount of Restricted Payments;

         (d) make a Restricted Payment, if at the time the Company or any
    Restricted Subsidiary first Incurred a commitment for such Restricted
    Payment, such Restricted Payment could have been made; provided, however,
    that all commitments Incurred and outstanding shall be treated as if such
    commitments were Restricted Payments expended by the Company or a Restricted
    Subsidiary at the time the commitments were Incurred, except that
    commitments Incurred and outstanding that are treated as a Restricted
    Payment expended by the Company or a Restricted Subsidiary and that are
    terminated shall no longer be treated as a Restricted Payment expended by
    the Company or a Restricted Subsidiary upon the termination of such
    commitment;

         (e) repurchase shares of, or options to purchase shares of, common
    stock of the Company or any of its Subsidiaries (or pay dividends on its
    Capital Stock for the purpose of enabling any direct or indirect parent
    company of the Company to repurchase shares of, or options to purchase
    shares of, its common stock) from current or former officers, directors or
    employees of the Company or any of its Subsidiaries or any direct or
    indirect parent holding company of the Company (or permitted transferees of
    such current or former officers, directors or employees), pursuant to the
    terms of agreements (including employment agreements) or plans (or
    amendments thereto) approved by the Board of Directors of the Company or
    such parent holding company under which such individuals purchase or sell,
    or are granted the option to purchase or sell, shares of such common stock;
    provided, however, that:

              (1) the aggregate amount of such repurchases (or such dividends
         made to facilitate such repurchases) shall not exceed $3.0 million in
         any calendar year, although any unused amount in any calendar year may
         be carried forward to one or more future calendar years, and

              (2) at the time of such repurchase (or such dividends made to
         facilitate such repurchases), no other Default or Event of Default
         shall have occurred and be continuing (or result therefrom);

    provided further, however, that such repurchases (or such dividends made to
    facilitate such repurchases) shall be included in the calculation of the
    amount of Restricted Payments;

         (f) make Investments in any Person, provided that the Fair Market Value
    thereof, measured on the date each such Investment was made or returned, as
    applicable, when taken together with all other Investments made pursuant to
    this clause (f), does not exceed the sum of $50.0 million, plus the
    aggregate amount of the net reduction in Investments in any Person made
    pursuant to this clause (f) on and after the Issue Date resulting from
    dividends, repayments of loans or other transfers of Property, in each case
    to the Company or any Restricted Subsidiary from such Person, except to the
    extent that any such net reduction amount is

                                       34
<PAGE>

    included in the amount calculated pursuant to clause (c) of the preceding
    paragraph or any other clause of this paragraph; provided, however, that at
    the time of such Investment, no other Default or Event of Default shall have
    occurred and be continuing (or result therefrom); provided further, however,
    that such Investment shall be included in the calculation of the amount of
    Restricted Payments;

         (g) make payments to any direct or indirect parent holding company of
    the Company for legal, audit and other expenses directly relating to the
    administration of such parent holding company, which payments do not exceed
    $2.0 million in any fiscal year; and

         (h) make direct or indirect payments to Alamosa Holdings, Inc.
    (together with any successor thereof, "Parent") in amounts necessary to
    enable Parent to make cash dividend payments with respect to either (i) the
    shares of Series B Convertible Preferred Stock issued by Parent pursuant to
    the Exchange Offers (or any securities issued in exchange therefor) or (ii)
    the shares of Series C Convertible Preferred Stock of Parent (or any
    securities issued in exchange therefor) issued by Parent as dividends on
    shares of either Series B Convertible Preferred Stock or Series C
    Convertible Preferred Stock.

         SECTION 4.05. Limitation on Liens. The Company shall not, and shall not
permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer to
exist, any Lien, other than Permitted Liens, upon any of its Property (including
Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or
thereafter acquired, or any interest therein or any income or profits therefrom,
unless it has made or will make effective provision whereby the Securities or
the applicable Subsidiary Guaranty will be secured by such Lien equally and
ratably with (or prior to) all other Debt of the Company or any Restricted
Subsidiary secured by such Lien.

         SECTION 4.06. Limitation on Issuance or Sale of Capital Stock of
Restricted Subsidiaries. The Company shall not:

         (a) sell, pledge, hypothecate or otherwise dispose of any shares of
    Capital Stock of a Restricted Subsidiary, except pledges of Capital Stock
    which constitute Permitted Liens, or

         (b) permit any Restricted Subsidiary to, directly or indirectly, issue
    or sell or otherwise dispose of any shares of its Capital Stock,

other than, in the case of either (a) or (b):

              (1) directors' qualifying shares,

              (2) to the Company or a Restricted Subsidiary,

              (3) a disposition of Capital Stock of such Restricted Subsidiary
         where immediately after giving effect thereto, either such Restricted
         Subsidiary remains a Restricted Subsidiary or the Company and the
         Restricted Subsidiaries no longer own any Capital Stock of such entity,
         provided, however, that, in the case of this clause (3),

                   (A) such issuance, sale or disposition is effected in
              compliance with Section 4.07, and

                                       35
<PAGE>

                   (B) upon consummation of any such disposition which results
              in the Company and the Restricted Subsidiaries no longer owning
              any Capital Stock of an entity and execution and delivery of a
              supplemental indenture in form satisfactory to the Trustee, such
              entity shall be released from any Subsidiary Guaranty previously
              made by such entity,

              (4) the transfer, conveyance, sale or other disposition of shares
         required by applicable law or regulation,

              (5) Capital Stock issued and outstanding on the Issue Date,

              (6) Capital Stock of a Restricted Subsidiary issued and
         outstanding prior to the time that such Person becomes a Restricted
         Subsidiary so long as such Capital Stock was not issued in
         contemplation of such Person's becoming a Restricted Subsidiary or
         otherwise being acquired by the Company, or

              (7) an issuance of Preferred Stock of a Restricted Subsidiary
         (other than Preferred Stock convertible or exchangeable into common
         stock of any Restricted Subsidiary) otherwise permitted by this
         Indenture.

         SECTION 4.07. Limitation on Asset Sales. The Company shall not, and
shall not permit any Restricted Subsidiary to, directly or indirectly,
consummate any Asset Sale unless:

         (a) the Company or such Restricted Subsidiary receives consideration at
    the time of such Asset Sale at least equal to the Fair Market Value of the
    Property subject to such Asset Sale;

         (b) at least 75% of the consideration paid to the Company or such
    Restricted Subsidiary in connection with such Asset Sale is in the form of
    cash or cash equivalents or Telecommunications Assets or the assumption by
    the purchaser of liabilities of the Company or any Restricted Subsidiary
    (other than liabilities that are by their terms subordinated to the
    Securities or the applicable Subsidiary Guaranty) as a result of which the
    Company and the Restricted Subsidiaries are no longer obligated with respect
    to such liabilities; and

         (c) the Company delivers an Officers' Certificate to the Trustee
    certifying that such Asset Sale complies with the foregoing clauses (a) and
    (b).

         The Net Available Cash (or any portion thereof) from Asset Sales may be
applied by the Company or a Restricted Subsidiary, to the extent the Company or
such Restricted Subsidiary elects (or is required by the terms of any Debt):

         (a) to Repay Senior Debt of the Company or any Subsidiary Guarantor
    (including the Senior Discount Notes, the Existing Notes and the
    Securities), or Debt of any Restricted Subsidiary that is not a Subsidiary
    Guarantor (excluding, in any such case, any Debt owed to the Company or an
    Affiliate of the Company); or

         (b) to reinvest in Additional Assets (including by means of an
    Investment in Additional Assets by a Restricted Subsidiary with Net
    Available Cash received by the Company or another Restricted Subsidiary).

         Any Net Available Cash from an Asset Sale not applied in accordance
with the preceding paragraph within 360 days from the date of the receipt of
such Net

                                       36

<PAGE>

Available Cash shall constitute "Excess Proceeds." When the aggregate amount of
Excess Proceeds exceeds $10.0 million (taking into account income earned on such
Excess Proceeds, if any), the Company will be required to make an offer to
purchase (the "Prepayment Offer") the Securities, which offer shall be in the
amount of the Allocable Excess Proceeds, on a pro rata basis according to
principal amount at a purchase price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the purchase date (subject
to the right of holders of record on the relevant record date to receive
interest due on the relevant interest payment date), in accordance with the
procedures (including prorating in the event of oversubscription) set forth
below. To the extent that any portion of the amount of Net Available Cash
remains after compliance with the preceding sentence and provided that all
Holders have been given the opportunity to tender their Securities for purchase
in accordance with this Section 4.07, the Company or such Restricted Subsidiary
may use such remaining amount for any purpose permitted by this Indenture and
the amount of Excess Proceeds will be reset to zero.

         The term "Allocable Excess Proceeds" will mean the product of:

         (a) the Excess Proceeds and

         (b) a fraction,

              (1) the numerator of which is the aggregate principal amount of
         the Securities outstanding on the date of the Prepayment Offer, and

              (2) the denominator of which is the sum of the aggregate principal
         amount of the Securities outstanding on the date of the Prepayment
         Offer and the aggregate principal amount (or if Incurred with original
         issue discount, the aggregate accreted value) of other Debt of the
         Company (including the Existing Notes and the Senior Discount Notes)
         outstanding on the date of the Prepayment Offer that is pari passu in
         right of payment with the Securities and subject to terms and
         conditions in respect of Asset Sales similar in all material respects
         to this Section 4.07 and requiring the Company to make an offer to
         purchase such Debt at substantially the same time as the Prepayment
         Offer.

         (d)(1) Within five Business Days after the Company is obligated to make
a Prepayment Offer as described in the preceding paragraph, the Company shall
send a written notice, by first-class mail, to the Holders (with a copy to the
Trustee), accompanied by such information regarding the Company and its
Subsidiaries as the Company in good faith believes will enable such Holders to
make an informed decision with respect to such Prepayment Offer. Such notice
shall state, among other things, the purchase price and the purchase date (the
"Purchase Date"), which shall be, subject to any contrary requirements of
applicable law, a business day no earlier than 30 days nor later than 60 days
from the date such notice is mailed.

         (2) Not later than the date upon which written notice of a Prepayment
Offer is delivered to the Trustee as provided above, the Company shall deliver
to the Trustee an Officers' Certificate as to (i) the amount of the Prepayment
Offer (the "Offer Amount"), (ii) the allocation of the Net Available Cash from
the Asset Sales pursuant to which such Prepayment Offer is being made and (iii)
the compliance of such allocation with the provisions of the second paragraph of
this Section 4.07. On or before the Purchase Date, the Company shall also
irrevocably deposit with the Trustee or with the Paying Agent (or, if the
Company or a Wholly Owned Subsidiary is the Paying Agent, shall segregate and
hold in trust) in Temporary Cash Investments (other than in those

                                       37
<PAGE>

enumerated in clause (b) of the definition of Temporary Cash Investments),
maturing on the last day prior to the Purchase Date or on the Purchase Date if
funds are immediately available by open of business, an amount equal to the
Offer Amount to be held for payment in accordance with the provisions of this
Section 4.07. Upon the expiration of the period for which the Prepayment Offer
remains open (the "Offer Period"), the Company shall deliver to the Trustee for
cancellation the Securities or portions thereof that have been properly tendered
to and are to be accepted by the Company. The Trustee or the Paying Agent shall,
on the Purchase Date, mail or deliver payment to each tendering Holder in the
amount of the purchase price. In the event that the aggregate purchase price of
the Securities delivered by the Company to the Trustee is less than the Offer
Amount, the Trustee or the Paying Agent shall deliver the excess to the Company
immediately after the expiration of the Offer Period for application in
accordance with this Section 4.07.

         (3) Holders electing to have a Security purchased shall be required to
surrender the Security, with an appropriate form duly completed, to the Company
or its agent at the address specified in the notice at least three Business Days
prior to the Purchase Date. Holders shall be entitled to withdraw their election
if the Trustee or the Company receives not later than one Business Day prior to
the Purchase Date a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Security that was
delivered for purchase by the Holder and a statement that such Holder is
withdrawing its election to have such Security purchased. If at the expiration
of the Offer Period the aggregate principal amount of Securities surrendered by
Holders exceeds the Offer Amount, the Company shall select the Securities to be
purchased on a pro rata basis for all Securities (with such adjustments as may
be deemed appropriate by the Company so that only Securities in denominations of
$1,000, or integral multiples thereof, shall be purchased). Holders whose
Securities are purchased only in part shall be issued new Securities equal in
principal amount to the unpurchased portion of the Securities surrendered.

         (4) At the time the Company delivers Securities to the Trustee that are
to be accepted for purchase, the Company shall also deliver an Officers'
Certificate stating that such Securities are to be accepted by the Company
pursuant to and in accordance with the terms of this Section 4.07. A Security
shall be deemed to have been accepted for purchase at the time the Trustee or
the Paying Agent mails or delivers payment therefor to the surrendering Holder.

         (e) The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section 4.07. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.07, the Company will
comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Section 4.07 by virtue
thereof.

         SECTION 4.08. Limitation on Restrictions on Distributions from
Restricted Subsidiaries. The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, create or otherwise cause or
suffer to exist any consensual restriction on the right of any Restricted
Subsidiary to:

         (a) pay dividends, in cash or otherwise, or make any other
    distributions on or in respect of its Capital Stock, or pay any Debt or
    other obligation owed, to the Company or any other Restricted Subsidiary,

                                       38

<PAGE>

         (b) make any loans or advances to the Company or any other Restricted
    Subsidiary, or

         (c) transfer any of its Property to the Company or any other Restricted
    Subsidiary.

The foregoing limitations will not apply:

         (1) with respect to clauses (a), (b) and (c), to restrictions:

              (A) contained in an agreement or instrument governing or relating
         to Debt contained in any Credit Facility outstanding pursuant to clause
         (b) of the definition of Permitted Debt in Section 4.03; provided,
         however, that:

                   (x) the provisions of any Credit Facilities with a Stated
              Maturity prior to the scheduled maturity date of the Securities
              must permit distributions to the Company for the sole purpose of,
              and in an amount sufficient to fund, the payment of interest when
              due as scheduled in respect of the Securities, and

                   (y) the provisions of any Credit Facilities with a Stated
              Maturity on or after the scheduled maturity date of the Securities
              must permit distributions to the Company for the sole purpose of,
              and in an amount sufficient to fund, the payment of principal at
              scheduled maturity and interest when due as scheduled in respect
              of the Securities

         (provided, in the case of both (x) and (y), that such payment is due or
         to become due within 30 days from the date of such distribution and the
         cash distributed is in fact utilized to meet such payment obligation),
         at a time, in the case of both (x) and (y), when there does not exist
         an event (or such distribution would not cause an event) which, with
         the passage of time or notice or both, would permit the lenders under
         any Credit Facility to declare all amounts thereunder due and payable;
         provided further, however, that such agreement or instrument may
         nevertheless contain customary financial covenants,

              (B) relating to Debt of a Restricted Subsidiary and existing at
         the time it became a Restricted Subsidiary if such restriction was not
         created in connection with or in anticipation of the transaction or
         series of transactions pursuant to which such Restricted Subsidiary
         became a Restricted Subsidiary or was acquired by the Company, or

              (C) that result from the Refinancing of Debt Incurred pursuant to
         an agreement referred to in clause (1)(A) or (B) above or in clause
         (2)(A) or (B) below, provided such restriction is not materially less
         favorable to the Holders than those under the agreement evidencing the
         Debt so Refinanced, and

         (2) with respect to clause (c) only, to restrictions:

              (A) relating to Debt that is permitted to be Incurred and secured
         without also securing the Securities or the applicable Subsidiary
         Guaranty

                                       39

<PAGE>

         pursuant to Sections 4.03 and 4.05 that limit the right of the
         debtor to dispose of the Property securing such Debt,

              (B) encumbering Property at the time such Property was acquired by
         the Company or any Restricted Subsidiary, so long as such restriction
         relates solely to the Property so acquired and was not created in
         connection with or in anticipation of such acquisition,

              (C) resulting from customary provisions restricting subletting or
         assignment of leases or licenses or customary provisions in other
         agreements that restrict assignment of such agreements or rights
         thereunder,

              (D) customarily contained in property sale agreements limiting the
         transfer of such Property pending the closing of such sale, or

              (E) customarily contained in Debt instruments limiting the sale of
         all or substantially all the assets of the obligor.

         SECTION 4.09. Limitation on Transactions with Affiliates. The Company
shall not, and shall not permit any Restricted Subsidiary to, directly or
indirectly, conduct any business or enter into or suffer to exist any
transaction or series of transactions (including the purchase, sale, transfer,
assignment, lease, conveyance or exchange of any Property or the rendering of
any service) with, or for the benefit of, any Affiliate of the Company (an
"Affiliate Transaction"), unless:

         (a) the terms of such Affiliate Transaction are:

              (1) set forth in writing, and

              (2) no less favorable to the Company or such Restricted
         Subsidiary, as the case may be, than those that could be obtained in a
         comparable arm's-length transaction with a Person that is not an
         Affiliate of the Company,

         (b) if such Affiliate Transaction involves aggregate payments or value
    in excess of $5.0 million, the Board of Directors (including a majority of
    the disinterested members of the Board of Directors) approves such Affiliate
    Transaction and, in its good faith judgment, believes that such Affiliate
    Transaction complies with clause (a)(2) of this paragraph, as evidenced by a
    Board Resolution promptly delivered to the Trustee, and

         (c) if such Affiliate Transaction involves aggregate payments or value
    in excess of $25.0 million, the Company obtains a written opinion from an
    Independent Financial Advisor to the effect that the consideration to be
    paid or received in connection with such Affiliate Transaction is fair, from
    a financial point of view, to the Company and the Restricted Subsidiaries,
    taken as a whole.

         Notwithstanding the foregoing limitation, the Company or any Restricted
Subsidiary may enter into or suffer to exist the following:

         (a) any transaction or series of transactions between the Company and
    one or more Restricted Subsidiaries or between two or more Restricted
    Subsidiaries, provided, however, that no more than 10% of the total voting
    power of the Voting

                                       40

<PAGE>

    Stock (on a fully diluted basis) of any such Restricted Subsidiary is owned
    by an Affiliate of the Company (other than a Restricted Subsidiary);

         (b) any Restricted Payment permitted to be made pursuant to Section
    4.04 or any Permitted Investment;

         (c) the payment of compensation (including amounts paid pursuant to
    employee benefit plans) and the provision of benefits for the personal
    services of officers, directors and employees of the Company or any of the
    Restricted Subsidiaries, so long as the Board of Directors in good faith
    shall have approved the terms thereof;

         (d) loans and advances to employees made in the ordinary course of
    business and consistent with the past practices of the Company or such
    Restricted Subsidiary, as the case may be, provided, however, that such
    loans and advances do not exceed $3.0 million in the aggregate at any one
    time outstanding; and

         (e) any transaction or series of transactions pursuant to any agreement
    in existence on the Issue Date, and any renewal, extension or replacement of
    such agreement on terms no less favorable to the Company and the Restricted
    Subsidiaries than the agreement in existence on the Issue Date.

         SECTION 4.10. Limitation on Layered Debt. The Company shall not permit
any Subsidiary Guarantor to Incur, directly or indirectly, any Debt that is
subordinate or junior in right of payment to any Senior Debt unless such debt is
expressly subordinated in right of payment to, or ranks pari passu with, the
Obligations under its Subsidiary Guaranty.

         SECTION 4.11. Designation of Restricted and Unrestricted Subsidiaries.
The Board of Directors may designate any Subsidiary of the Company to be an
Unrestricted Subsidiary if:

         (a) the Subsidiary to be so designated does not own any Capital Stock
    or Debt of, or own or hold any Lien on any Property of, the Company or any
    other Restricted Subsidiary,

         (b) either:

              (1) the Subsidiary to be so designated has total assets of $1,000
         or less, or

              (2) such designation is effective either immediately upon such
         entity becoming a Subsidiary of the Company or as of the date hereof,
         and

         (c) neither the Company nor any Restricted Subsidiary is directly or
    indirectly liable for any Debt that provides that the holder thereof may
    (with the passage of time or notice or both) declare a default thereon or
    cause the payment thereof to be accelerated or payable prior to its Stated
    Maturity upon the occurrence of a default with respect to any Debt, Lien or
    other obligation of the Subsidiary to be so designated (including any right
    to take enforcement action against the Subsidiary to be so designated).

Unless so designated as an Unrestricted Subsidiary, any Person that becomes a
Subsidiary of the Company will be classified as a Restricted Subsidiary;
provided, however, that

                                       41

<PAGE>

such Subsidiary shall not be designated a Restricted Subsidiary and shall be
automatically classified as an Unrestricted Subsidiary if either of the
requirements set forth in clauses (x) and (y) of the third immediately following
paragraph will not be satisfied after giving pro forma effect to such
classification or if such Person is a Subsidiary of an Unrestricted Subsidiary.

         In addition, neither the Company nor any Restricted Subsidiary shall
become directly or indirectly liable for any Debt that provides that the holder
thereof may (with the passage of time or notice or both) declare a default
thereon or cause the payment thereof to be accelerated or payable prior to its
Stated Maturity upon the occurrence of a default with respect to any Debt, Lien
or other obligation of any Unrestricted Subsidiary (including any right to take
enforcement action against such Unrestricted Subsidiary).

         Except as provided in the first sentence of the next preceding
paragraph, no Restricted Subsidiary may be redesignated as an Unrestricted
Subsidiary. Upon designation of a Restricted Subsidiary as an Unrestricted
Subsidiary in compliance with this Section 4.11, such Restricted Subsidiary
shall, by execution and delivery of a supplemental indenture in form
satisfactory to the Trustee, be released from any Subsidiary Guaranty previously
made by such Restricted Subsidiary.

         The Board of Directors may designate any Unrestricted Subsidiary to be
a Restricted Subsidiary if, immediately after giving pro forma effect to such
designation,

         (x) the Company could Incur at least $1.00 of additional Debt pursuant
    to clause (1) of the first paragraph of Section 4.03, and

         (y) no Default or Event of Default shall have occurred and be
    continuing or would result therefrom.

         Any such designation or redesignation by the Board of Directors will be
evidenced to the Trustee by filing with the Trustee a Board Resolution giving
effect to such designation or redesignation and an Officers' Certificate that:

         (a) certifies that such designation or redesignation complies with the
    foregoing provisions, and

         (b) gives the effective date of such designation or redesignation, such
    filing with the Trustee to occur within 45 days after the end of the fiscal
    quarter of the Company in which such designation or redesignation is made
    (or, in the case of a designation or redesignation made during the last
    fiscal quarter of the Company's fiscal year, within 90 days after the end of
    such fiscal year).

         SECTION 4.12. Limitation on Sale and Leaseback Transactions. The
Company shall not, and shall not permit any Restricted Subsidiary to, enter into
any Sale and Leaseback Transaction with respect to any Property unless:

         (a) the Company or such Restricted Subsidiary would be entitled to:

              (1) Incur Debt in an amount equal to the Attributable Debt with
         respect to such Sale and Leaseback Transaction pursuant to Section
         4.03, and

                                       42

<PAGE>

              (2) create a Lien on such Property securing such Attributable Debt
         without also securing the Securities or the applicable Subsidiary
         Guaranty pursuant to Section 4.05, and

         (b) such Sale and Leaseback Transaction is effected in compliance with
    Section 4.07.

         SECTION 4.13. Limitation on Company's Business. The Company shall not,
and shall not permit any Restricted Subsidiary to, engage in any business other
than the Telecommunications Business.

         SECTION 4.14. Change of Control. Upon the occurrence of a Change of
Control, each Holder shall have the right to require the Company to repurchase
all or any part of such Holder's Securities pursuant to the offer described
below (the "Change of Control Offer") at a purchase price (the "Change of
Control Purchase Price") equal to 101.0% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the purchase date (subject to the right
of Holders of record on the relevant record date to receive interest due on the
relevant interest payment date).

         Within 30 days following any Change of Control, the Company shall

         (a) cause a notice of the Change of Control Offer to be sent at least
    once to the Dow Jones News Service or a similar business news service in the
    United States, and

         (b) send, by first-class mail, with a copy to the Trustee, to each
    Holder of Securities, at such Holder's address appearing in the Security
    Register, a notice stating:

              (1) that a Change of Control Offer is being made pursuant to this
         Section 4.14 and that all Securities timely tendered will be accepted
         for payment;

              (2) the Change of Control Purchase Price and the purchase date,
         which shall be, subject to any contrary requirements of applicable law,
         a Business Day no earlier than 30 days nor later than 60 days from the
         date such notice is mailed (the "Change of Control Payment Date");

              (3) that any Security (or portion thereof) accepted for payment
         (and duly paid on the Change of Control Payment Date) pursuant to the
         Change of Control Offer shall cease to accrete interest after the
         Change of Control Payment Date;

              (4) that any Security (or portions thereof) not properly tendered
         will continue to accrete interest;

              (5) the circumstances and relevant facts regarding the Change of
         Control (including, if and to the extent material, information with
         respect to pro forma historical income, cash flow and capitalization
         after giving effect to the Change of Control); and

              (6) the procedures that Holders must follow in order to tender
         their Securities (or portions thereof) for payment and the procedures
         that

                                       43

<PAGE>

         Holders must follow in order to withdraw an election to tender
         Securities (or portions thereof) for payment.

         Holders electing to have a Security purchased shall be required to
surrender the Security, with an appropriate form duly completed, to the Company
or its agent at the address specified in the notice at least three Business Days
prior to the Change of Control Payment Date. Holders shall be entitled to
withdraw their election if the Trustee or the Company receives not later than
one Business Day prior to the Change of Control Payment Date a telegram, telex,
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of the Security that was delivered for purchase by the Holder
and a statement that such Holder is withdrawing its election to have such
Security purchased.

         On or prior to the Change of Control Payment Date, the Company shall
irrevocably deposit with the Trustee or with the Paying Agent (or, if the
Company or any of its Wholly Owned Subsidiaries is acting as the Paying Agent,
segregate and hold in trust) in cash an amount equal to the Change of Control
Purchase Price payable to the Holders entitled thereto, to be held for payment
in accordance with the provisions of this Section 4.14. On the Change of Control
Payment Date, the Company shall deliver to the Trustee the Securities or
portions thereof that have been properly tendered to and are to be accepted by
the Company for payment. The Trustee or the Paying Agent shall, on the Change of
Control Payment Date, mail or deliver payment to each tendering Holder of the
Change of Control Purchase Price. In the event that the aggregate Change of
Control Purchase Price is less than the amount delivered by the Company to the
Trustee or the Paying Agent, the Trustee or the Paying Agent, as the case may
be, shall deliver the excess to the Company immediately after the Change of
Control Payment Date.

         The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the purchase of Securities pursuant to this
Section 4.14. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Section 4.14, the Company will
comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Section 4.14 by virtue
thereof.

         SECTION 4.15. Future Subsidiary Guarantors. The Company shall cause
each Person that becomes a Domestic Restricted Subsidiary following the Issue
Date to become a Subsidiary Guarantor by causing such Person to execute and
deliver to the Trustee a Supplemental Indenture as provided in Section 10.06 at
the time such Person becomes a Domestic Restricted Subsidiary.

         SECTION 4.16. Compliance Certificate. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate stating that in the course of the performance by the
signers of their duties as Officers of the Company they would normally have
knowledge of any Default and whether or not the signers know of any Default that
occurred during such period. If they do, the certificate shall describe the
Default, its status and what action the Company is taking or proposes to take
with respect thereto. The Company also shall comply with TIA ss. 314(a)(4).

         SECTION 4.17. OID Certificate. If upon issuance of the Securities the
Company determines that the Securities will be issued with "Original Issue
Discount," as defined by the Code, within 30 days after the end of each calendar
year, the Company shall deliver to the Trustee a certificate setting forth the
following:

                                       44

<PAGE>

         (a) the total cumulative amount of Original Issue Discount that had
    accrued on the Securities as of December 31 of such calendar year;

         (b) the portion of such Original Issue Discount that had accrued during
    such calendar year; and

         (c) such other specific information relating to the accrued Original
    Issue Discount of the Securities as may be relevant under the Code to the
    holders of the Securities.

         SECTION 4.18. Information Reporting. If upon issuance of the Securities
the Company determines that the Securities will be issued with "Original Issue
Discount," as defined by the Code within 30 days after the Issue Date, the
Company shall file an information return on Form 8281 in accordance with
Treasury Regulation ss. 1.1275-3(c). The Company shall be responsible for the
timely preparation and delivery of all annual information returns required under
the Code and applicable Treasury Regulations including, without limitation, the
timely preparation and delivery of IRS Form 1099-OID.

         SECTION 4.19. Further Instruments and Acts. Upon request of the
Trustee, the Company shall execute and deliver such further instruments and do
such further acts as may be reasonably necessary or proper to carry out more
effectively the purpose of this Indenture.

    Trustee, in form and substance reasonably satisfactory to the Trustee, an
    Officers' Certificate and an Opinion of Counsel, each stating that such
    transaction and such Subsidiary Guaranty, if any, in respect thereto comply
    with this Section 5.02 and that all conditions precedent herein provided for
    relating to such transaction have been satisfied.

The foregoing provisions (other than clause (d)) shall not apply to any
transactions which constitute an Asset Sale if the Company has complied with

Subsidiary Guarantor under the Subsidiary Guaranty, as the case may be), but the
predecessor Company in the case of:

         (a) a sale, transfer, assignment, conveyance or other disposition
    (unless such sale, transfer, assignment, conveyance or other disposition is
    of all the assets of the Company as an entirety or virtually as an
    entirety), or

    period of 30 days;

         (2) the Company defaults in the payment of principal of, or premium, if

    repurchase or otherwise;

         (3) the Company or any Subsidiary Guarantor fails to comply with
    Article V;

         (4) the Company fails to comply with any covenant or agreement in the

    the foregoing clause (1), (2) or (3)) and such failure continues for 30 days
    after written notice is given to the Company as specified below;

         (5) a default by the Company or any Restricted Subsidiary under any
    Debt of the Company or any Restricted Subsidiary which results in
    acceleration of the maturity of such Debt, or the failure to pay any such
    Debt at maturity, in an aggregate amount in excess of $15.0 million;

         (6) the Company or any Significant Subsidiary pursuant to or within the
    meaning of any Bankruptcy Law:

              (A) commences a voluntary case;

              (B) consents to the entry of an order for relief against it in an
         involuntary case;

              (C) consents to the appointment of a Custodian of it or for any
         substantial part of its property; or

              (D) makes a general assignment for the benefit of its creditors;

    or takes any comparable action under any foreign laws relating to
    insolvency;

         (7) a court of competent jurisdiction enters an order or decree under

    obligations under its Subsidiary Guaranty; or

         (10) any event occurs that causes, after giving effect to the
    expiration of any applicable grace period, an Event of Termination.

         The foregoing will constitute Events of Default whatever the reason for
any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

         The term "Bankruptcy Law" means Title 11, United States Code, or any
similar U.S. federal or state law for the relief of debtors. The term
"Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

         A Default under clause (4) is not an Event of Default until the Trustee
or the Holders of at least 25% in aggregate principal amount of the Securities
then outstanding notify the Company (and in the case of such notice by Holders,
the Trustee) of the Default and the Company does not cure such Default within
the time specified after receipt of such notice. Such notice must specify the
Default, demand that it be remedied and state that such notice is a "Notice of
Default".

         The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default and any event that with the giving of notice or the lapse
of time would become an Event of Default, its status and what action the Company
is taking or proposes to take with respect thereto.

         SECTION 6.02. Acceleration. If an Event of Default (other than an Event
of Default specified in Section 6.01(6) or (7) with respect to the Company)
occurs and is continuing, the Trustee by notice to the Company, or the Holders
of at least 25% in aggregate principal amount of the Securities then outstanding
by notice to the Company and the Trustee, may declare the principal amount of
and accrued and unpaid interest on all the Securities to be due and payable.
Upon such a declaration, such principal amount and interest shall be due and
payable immediately. If an Event of Default specified in Section 6.01(6) or (7)
with respect to the Company occurs, the principal amount of and accrued and
unpaid interest on all the Securities shall, automatically and without any
action by the Trustee or any Holder, become and be immediately due and payable.
The

                                       49

<PAGE>

Holders of a majority in aggregate principal amount of the outstanding
Securities by notice to the Trustee and the Company may rescind any declaration
of acceleration 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. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

         SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

         SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in
aggregate principal amount of the Securities then outstanding by notice to the
Trustee may waive an existing Default and its consequences except (i) a Default
in the payment of the principal of or the premium, if any, or interest on a
Security, or (ii) a Default in respect of a provision that under Section 9.02
cannot be amended without the consent of each Securityholder affected. When a
Default is waived, it is deemed cured, but no such waiver shall extend to any
subsequent or other Default or impair any consequent right.

         SECTION 6.05. Control by Majority. The Holders of a majority in
aggregate principal amount of the Securities then outstanding may direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or of exercising any trust or power conferred on the Trustee with
respect to the Securities. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture or, subject to Section 7.01,
that the Trustee determines is unduly prejudicial to the rights of other
Securityholders or would involve the Trustee in personal liability; provided,
however, that the Trustee may take any other action deemed proper by the Trustee
that is not inconsistent with such direction. Prior to taking any action
hereunder, the Trustee shall be entitled to reasonable indemnification against
all losses and expenses caused by taking or not taking such action.

         SECTION 6.06. Limitation on Suits. A Securityholder may not pursue any
remedy with respect to this Indenture or the Securities unless:

              (1) such Holder shall have previously given to the Trustee written
         notice of a continuing Event of Default;

              (2) the Holders of at least 25% in aggregate principal amount of
         the Securities then outstanding shall have made a written request, and
         such Holder or Holders shall have offered reasonable indemnity to the
         Trustee to pursue such proceeding as trustee; and

              (3) the Trustee has failed to institute such proceeding and has
         not received from the Holders of at least a majority in aggregate
         principal amount of the Securities outstanding a direction inconsistent
         with such request, within 60 days after such notice, request and offer.

                                       50

<PAGE>

         The foregoing limitations on the pursuit of remedies by a
Securityholder shall not apply to a suit instituted by a Holder of Securities
for the enforcement of payment of the principal of or premium, if any, or
interest on such Security on or after the applicable due date specified in such
Security. A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over another
Securityholder.

         SECTION 6.07. Rights of Holders To Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal of and premium, if any, and interest on the Securities held by such
Holder, on or after the respective due dates expressed in the Securities, or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

         SECTION 6.08. Collection Suit by Trustee. If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

         SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

         SECTION 6.10. Priorities. If the Trustee collects any money or property
pursuant to this Article VI, it shall pay out the money or property in the
following order:

         FIRST: to the Trustee for amounts due under Section 7.07;

         SECOND: to Securityholders for amounts due and unpaid on the Securities
    for principal, premium, if any, and interest, ratably, without preference or
    priority of any kind, according to the amounts due and payable on the
    Securities for principal, premium, if any, and interest, respectively; and

         THIRD: to the Company.

         The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section. At least 15 days before such record
date, the Company shall mail to each Securityholder and the Trustee a notice
that states the record date, payment date and amount to be paid.

         SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or

                                       51

<PAGE>

defenses made by the party litigant. This Section 6.11 does not apply to a suit
by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders
of more than 10% in aggregate principal amount of the Securities.

         SECTION 6.12. Waiver of Stay or Extension Laws. The Company (to the
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution
of any power herein granted to the Trustee but shall suffer and permit the
execution of every such power as though no such law had been enacted.

                                   ARTICLE VII

                                     Trustee

         SECTION 7.01. Duties of Trustee. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

         (b) Except during the continuance of an Event of Default:

         (1) the Trustee undertakes to perform such duties and only such duties
    as are specifically set forth in this Indenture and no implied covenants or
    obligations shall be read into this Indenture against the Trustee; and

         (2) in the absence of bad faith on its part, the Trustee may
    conclusively rely, as to the truth of the statements and the correctness of
    the opinions expressed therein, upon certificates or opinions furnished to
    the Trustee and conforming to the requirements of this Indenture. However,
    the Trustee shall examine the certificates and opinions to determine whether
    or not they conform to the requirements of this Indenture.

         (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own wilful misconduct,
except that:

         (1) this paragraph does not limit the effect of paragraph (b) of this
    Section 7.01;

         (2) the Trustee shall not be liable for any error of judgment made in
    good faith by a Trust Officer unless it is proved that the Trustee was
    negligent in ascertaining the pertinent facts; and

         (3) the Trustee shall not be liable with respect to any action it takes
    or omits to take in good faith in accordance with a direction received by it
    pursuant to Section 6.05.

         (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01.

                                       52

<PAGE>

         (e) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Company.

         (f) Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

         (g) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur financial liability in the performance
of any of its duties hereunder or in the exercise of any of its rights or
powers.

         (h) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section 7.01 and to the provisions of the TIA
and the provisions of this Article VII shall apply to the Trustee in its role as
Registrar, Paying Agent and Custodian.

         (i) The Trustee shall not be deemed to have notice of a Default or an
Event of Default unless (a) the Trustee has received written notice thereof from
the Company or any Holder, or (b) a Trust Officer shall have actual knowledge
thereof.

         SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on any
document believed by it to be genuine and to have been signed or presented by
the proper person. The Trustee need not investigate any fact or matter stated in
the document. The Trustee may, however, in its discretion make such further
inquiry or investigation into such facts or matters as it may see fit and, if
the Trustee shall determine to make such further inquiry or investigation, it
shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney.

         (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable
for any action it takes or omits to take in good faith in reliance on the
Officers' Certificate or Opinion of Counsel.

         (c) The Trustee may act through agents and shall not be responsible for
the misconduct or negligence of any agent appointed with due care.

         (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith that it believes to be authorized or within its rights or
powers; provided, however, that the Trustee's conduct does not constitute wilful
misconduct or negligence.

         (e) The Trustee may consult with counsel, and the advice or opinion of
counsel with respect to legal matters relating to this Indenture and the
Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

         (f) The permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty unless so specified herein.

         SECTION 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar or
co-registrar may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11.

                                       53

<PAGE>

         SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity, priority or
adequacy of this Indenture or the Securities, it shall not be accountable for
the Company's use of the proceeds from the Securities, and it shall not be
responsible for any statement of the Company or any Subsidiary Guarantor in this
Indenture or in any document issued in connection with the sale of the
Securities or in the Securities other than the Trustee's certificate of
authentication.

         SECTION 7.05. Notice of Defaults. If a Default or Event of Default
occurs and is continuing and if it is known to the Trustee, the Trustee shall
mail to each Securityholder notice of the Default or Event of Default within 90
days after it is known to a Trust Officer or written notice of it is received by
the Trustee. Except in the case of a Default or Event of Default in payment of
principal of, premium, if any, or interest on any Security, the Trustee may
withhold the notice if and so long as a committee of its Trust Officers in good
faith determines that withholding the notice is in the interests of
Securityholders.

         SECTION 7.06. Reports by Trustee to Holders. As promptly as practicable
after each December 31 beginning with December 31, 2003, and in any event prior
to March 31 in each year, the Trustee shall mail to each Securityholder a brief
report dated as of December 31 each year that complies with TIA ss. 313(a), if
and to the extent required by such subsection. The Trustee shall also comply
with TIA ss. 313(b).

         A copy of each report at the time of its mailing to Securityholders
shall be filed with the Commission and each stock exchange (if any) on which the
Securities are listed. The Company agrees to notify promptly the Trustee
whenever the Securities become listed on any stock exchange and of any delisting
thereof.

         SECTION 7.07. Compensation and Indemnity. The Company shall pay to the
Trustee from time to time reasonable compensation for its services. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of- pocket expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts. The Company and each Subsidiary Guarantor, jointly and severally, shall
indemnify the Trustee against any and all loss, liability or expense (including
reasonable attorneys' fees) incurred by it in connection with the acceptance and
administration of this trust and the performance of its duties hereunder. The
Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company or any Subsidiary Guarantor of its obligations hereunder. The Company
shall defend the claim and the Trustee may have separate counsel and the Company
and the Subsidiary Guarantors, as applicable, shall pay the fees and expenses of
such counsel. The Company need not reimburse any expense or indemnify against
any loss, liability or expense incurred by the Trustee through the Trustee's own
wilful misconduct, negligence or bad faith. The Company need not pay for any
settlement made by the Trustee without the Company's consent, such consent not
to be unreasonably withheld. All indemnifications and releases from liability
granted hereunder to the Trustee shall extend to its officers, directors,
employees, agents, successors and assigns.

         To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities.

                                       54

<PAGE>

         The Company's payment obligations pursuant to this Section 7.07 shall
survive the resignation or removal of the Trustee and the discharge of this
Indenture. When the Trustee incurs expenses after the occurrence of a Default
specified in Section 6.01(6) or (7) with respect to the Company, the expenses
are intended to constitute expenses of administration under the Bankruptcy Law.

         SECTION 7.08. Replacement of Trustee. The Trustee may resign at any
time by so notifying the Company. The Holders of a majority in aggregate
principal amount of the Securities then outstanding may remove the Trustee by so
notifying the Trustee and may appoint a successor Trustee. The Company shall
remove the Trustee if:

         (1) the Trustee fails to comply with Section 7.10;

         (2) the Trustee is adjudged bankrupt or insolvent;

         (3) a receiver or other public officer takes charge of the Trustee or
    its property; or

         (4) the Trustee otherwise becomes incapable of acting.

         If the Trustee resigns, is removed by the Company or by the Holders of
a majority in aggregate principal amount of the Securities then outstanding and
such Holders do not reasonably promptly appoint a successor Trustee, or if a
vacancy exists in the office of Trustee for any reason (the Trustee in such
event being referred to herein as the retiring Trustee), the Company shall
promptly appoint a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

         If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of
10% in aggregate principal amount of the Securities then outstanding may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

         If the Trustee fails to comply with Section 7.10, any Securityholder
who has been a bona fide Holder of a Security for at least six months may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

         Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

         SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation or banking
association without any further act shall be the successor Trustee.

                                       55

<PAGE>

         In case at the time such successor or successors by merger, conversion
or consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the Trustee may adopt the certificate of authentication of
any predecessor trustee, and deliver such Securities so authenticated; and in
case at that time any of the Securities shall not have been authenticated, any
such successor to the Trustee may authenticate such Securities either in the
name of any predecessor hereunder or in the name of the successor to the
Trustee; and in all such cases such certificates shall have the full force which
it is anywhere in the Securities or in this Indenture provided that the
certificate of the Trustee shall have.

         SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all
times satisfy the requirements of TIA ss. 310(a). The Trustee shall have (or, in
the case of a corporation included in a bank holding company system, the related
bank holding company shall have) a combined capital and surplus of at least
$150.0 million as set forth in its (or its related bank holding company's) most
recent published annual report of condition. The Trustee shall comply with TIA
ss. 310(b), subject to the penultimate paragraph thereof; provided, however,
that there shall be excluded from the operation of TIA ss. 310(b)(1) any
indenture or indentures under which other securities or certificates of interest
or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in TIA ss. 310(b)(1) are met.

         SECTION 7.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA ss. 311(a), excluding any creditor relationship
listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be
subject to TIA ss. 311(a) to the extent indicated.

                                  ARTICLE VIII

                       Discharge of Indenture; Defeasance

         SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a)
When (i) the Company delivers to the Trustee all outstanding Securities (other
than Securities replaced pursuant to Section 2.06) for cancellation, or (ii) all
outstanding Securities have become due and payable, whether at maturity or as a
result of the mailing of a notice of redemption pursuant to Article III and the
Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities, including interest
thereon to maturity or such redemption date (other than Securities replaced
pursuant to Section 2.06), and if in either case the Company pays all other sums
payable hereunder by the Company, then this Indenture shall, subject to Section
8.01(c), cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company.

         (b) Subject to Sections 8.01(c) and 8.02, the Company at any time may
terminate (i) all of its obligations under the Securities and this Indenture
("legal defeasance option"), or (ii) its obligations under Sections 4.02, 4.03,
4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and 4.15 and
the operation of Sections 6.01(5), 6.01(6), 6.01(7), 6.01(8), 6.01(9) and
6.01(10) (but, in the case of Sections 6.01(6) and (7), with respect only to
Significant Subsidiaries) and the limitations contained in clause (e) of
Sections 5.01 and 5.02 ("covenant defeasance option"). The Company may exercise
its legal defeasance option notwithstanding its prior exercise of its covenant
defeasance option.

                                       56

         If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default. If the Company
exercises its covenant defeasance option, payment of the Securities may not be
accelerated because of an Event of Default specified in Sections 6.01(4) (with
respect to the covenants of Article IV identified in the immediately preceding
paragraph), 6.01(5), 6.01(6), 6.01(7), 6.01(8), 6.01(9) and 6.01(10) (but, in
the case of Sections 6.01(6) and (7), with respect only to Significant
Subsidiaries) or because of the failure of the Company to comply with the
limitations contained in clause (e) of Sections 5.01 and 5.02. If the Company
exercises its legal defeasance option or its covenant defeasance option, each
Subsidiary Guarantor, if any, shall be released from all its obligations under
its Subsidiary Guarantee.

         Upon satisfaction of the conditions set forth herein and upon request
of the Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

         (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 7.07, 7.08, 8.05 and 8.06 shall
survive until the Securities have been paid in full. Thereafter, the Company's
obligations in Sections 7.07 and 8.05 shall survive.

         SECTION 8.02. Conditions to Defeasance. The Company may exercise its
legal defeasance option or its covenant defeasance option only if:

         (1) the Company irrevocably deposits in trust with the Trustee money or
    U.S. Government Obligations for the payment of principal of and premium, if
    any, and interest on the Securities to maturity or redemption, as the case
    may be;

         (2) the Company delivers to the Trustee a certificate from a nationally
    recognized firm of independent accountants expressing their opinion that the
    payments of principal, premium, if any, and interest when due and without
    reinvestment on the deposited U.S. Government Obligations plus any deposited
    money without investment will provide cash at such times and in such amounts
    as will be sufficient to pay the principal, premium, if any, and interest
    when due on all the Securities to maturity or redemption, as the case may
    be;

         (3) 123 days pass after the deposit is made and during the 123-day
    period no Default specified in Section 6.01(6) or (7) with respect to the
    Company occurs that is continuing at the end of the period;

         (4) no Default or Event of Default has occurred and is continuing on
    the date of such deposit and after giving effect thereto;

         (5) the deposit does not constitute a default under any other agreement
    or instrument binding on the Company;

         (6) the Company delivers to the Trustee an Opinion of Counsel to the
    effect that the trust resulting from the deposit does not constitute, or is
    qualified as, a regulated investment company under the Investment Company
    Act of 1940;

         (7) in the case of the legal defeasance option, the Company shall have
    delivered to the Trustee an Opinion of Counsel stating that (i) the Company
    has received from, or there has been published by, the Internal Revenue
    Service a ruling, or (ii) since the date of this Indenture there has been a
    change in the applicable U.S. federal income tax law, in either case to the
    effect that, and based

                                       57

<PAGE>

    thereon such Opinion of Counsel shall confirm that, the Securityholders will
    not recognize income, gain or loss for U.S. federal income tax purposes as a
    result of such defeasance and will be subject to U.S. federal income tax on
    the same amounts, in the same manner and at the same times as would have
    been the case if such defeasance had not occurred;

         (8) in the case of the covenant defeasance option, the Company shall
    have delivered to the Trustee an Opinion of Counsel to the effect that the
    Securityholders will not recognize income, gain or loss for U.S. federal
    income tax purposes as a result of such covenant defeasance and will be
    subject to U.S. federal income tax on the same amounts, in the same manner
    and at the same times as would have been the case if such covenant
    defeasance had not occurred; and

         (9) the Company delivers to the Trustee an Officers' Certificate and an
    Opinion of Counsel, each stating that all conditions precedent to the
    defeasance and discharge of the Securities as contemplated by this Article
    VIII have been complied with.

         Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article III.

         SECTION 8.03. Application of Trust Money. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to this
Article VIII. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and premium, if any, and interest on
the Securities.

         SECTION 8.04. Repayment to Company. The Trustee and the Paying Agent
shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

         Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon request any money held by them for
the payment of principal, premium, if any, or interest that remains unclaimed
for two years, and, thereafter, Securityholders entitled to the money must look
to the Company for payment as general creditors.

         SECTION 8.05. Indemnity for Government Obligations. The Company shall
pay and shall indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against deposited U.S. Government Obligations or the principal
and interest received on such U.S. Government Obligations.

         SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with this
Article VIII by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article VIII until such time as the
Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article VIII; provided, however, that, if
the Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the

                                       58

<PAGE>

Holders of such Securities to receive such payment from the money or U.S.
Government Obligations held by the Trustee or Paying Agent.

                                   ARTICLE IX

                                   Amendments

         SECTION 9.01. Without Consent of Holders. The Company, the Subsidiary
Guarantors and the Trustee may amend this Indenture or the Securities without
notice to or consent of any Securityholder:

         (1) to cure any ambiguity, omission, defect or inconsistency;

         (2) to comply with Article V;

         (3) to provide for uncertificated Securities in addition to or in place
    of certificated Securities; provided, however, that the uncertificated
    Securities are issued in registered form for purposes of Section 163(f) of
    the Code or in a manner such that the uncertificated Securities are
    described in Section 163(f)(2)(B) of the Code;

         (4) to make any change in Article XI that would limit or terminate the
    benefits available to any holder of Designated Senior Debt (or
    representatives therefor) under Article XI;

         (5) to add Guarantees with respect to the Securities, to secure the
    Securities or to release Subsidiary Guarantors from Subsidiary Guaranties as
    provided by the terms of this Indenture;

         (6) to add to the covenants of the Company for the benefit of the
    Holders or to surrender any right or power herein conferred upon the
    Company;

         (7) to comply with any requirements of the Commission in connection
    with qualifying, or maintaining the qualification of, this Indenture under
    the TIA; or

         (8) to make any change that does not adversely affect the rights of any
    Securityholder.

         An amendment under this Section may not make any change that adversely
affects the rights under Article X or XI of any holder of Designated Senior Debt
then outstanding unless the holders of such Designated Senior Debt (or their
authorized representatives) consent to such change.

         After an amendment under this Section 9.01 becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section 9.01.

         SECTION 9.02. With Consent of Holders. The Company, the Subsidiary
Guarantors and the Trustee may amend this Indenture or the Securities without
notice to any Securityholder but with the written consent of the Holders of at
least a majority in aggregate principal amount of the Securities then
outstanding (including consents

                                       59

<PAGE>

obtained in connection with a tender offer or exchange offer for the
Securities). However, without the consent of each Securityholder affected
thereby, an amendment may not:

         (1) reduce the amount of Securities whose Holders must consent to an
    amendment or waiver;

         (2) reduce the rate of or extend the time for payment of interest on
    any Security;

         (3) reduce the principal amount of or extend the Stated Maturity of any
    Security;

         (4) impair the right of any Holder to receive payment of principal of
    and interest on such Holder's Securities on or after the due dates therefor
    or to institute suit for the enforcement of any payment on or with respect
    to such Holder's Securities or any Subsidiary Guaranty;

         (5) reduce the amount payable upon the redemption or repurchase of any
    Security under Article III or Section 4.07 or 4.14, change the time at which
    any Security may be redeemed in accordance with Article III, or, at any time
    after a Change of Control or Asset Sale has occurred, change the time at
    which any Change of Control Offer or Prepayment Offer must be made or at
    which the Securities must be repurchased pursuant to such Change of Control
    Offer or Prepayment Offer;

         (6) make any Security payable in money other than that stated in the
    Security;

         (7) make any change in Article XI that adversely affects the rights of
    any Securityholder under Article XI;

         (8) make any change in any Subsidiary Guaranty that would adversely
    affect the Securityholders;

         (9) release any security interest that may have been granted in favor
    of the Holders other than pursuant to the terms of such security interest;

         (10) make any change in Section 6.04 or 6.07 or the second sentence of
    this Section 9.02; or

         (11) subordinate the Securities or any Subsidiary Guaranty to any other
    obligation of the Company or the applicable Subsidiary Guarantor.

         It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof.

         An amendment under this Section 9.02 may not make any change that
adversely affects the rights under Article X or XI of any holder of Designated
Senior Debt then outstanding unless the holders of such Designated Senior Debt
(or their authorized representative) consent to such change.

         After an amendment under this Section 9.02 becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The

                                       60
<PAGE>

failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section 9.02.

         SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to
this Indenture or the Securities shall comply with the TIA as then in effect.

         SECTION 9.04. Revocation and Effect of Consents and Waivers. A consent
to an amendment or a waiver by a Holder of a Security shall bind the Holder and
every subsequent Holder of that Security or portion of the Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent or waiver as to such Holder's Security
or portion of the Security if the Trustee receives the notice of revocation
before the date the amendment or waiver becomes effective. After an amendment or
waiver becomes effective, it shall bind every Securityholder. An amendment or
waiver becomes effective upon the execution of such amendment or waiver by the
Trustee.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Securityholders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Securityholders at such
record date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date. No such consent shall be valid or effective for more than 120
days after such record date.

         SECTION 9.05. Notation on or Exchange of Securities. If an amendment
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver such Security to the Trustee. The Trustee may place an
appropriate notation on the Security regarding the changed terms and return such
Security to the Holder. Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Security shall issue and the Trustee
shall authenticate a new Security that reflects the changed terms. Failure to
make the appropriate notation or to issue a new Security shall not affect the
validity of such amendment.

         SECTION 9.06. Trustee To Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article IX if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture.

         SECTION 9.07. Payment for Consent. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

                                    ARTICLE X

                              Subsidiary Guarantees

         SECTION 10.01. Subsidiary Guarantees. Subject to Article XI, each
Subsidiary Guarantor hereby unconditionally guarantees, jointly and severally,
to each Holder and to the Trustee and its successors and assigns (a) the full
and punctual payment of the principal of, and premium, if any, and interest on
the Securities when due, whether at maturity, by acceleration, by redemption or
otherwise, and all other monetary obligations of the Company under this
Indenture and the Securities, and (b) the full and punctual performance within
applicable grace periods of all other obligations of the Company under this
Indenture and the Securities (all the foregoing being hereinafter collectively
called the "Obligations"). Each Subsidiary Guarantor further agrees that the
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from such Subsidiary Guarantor, and that such Subsidiary
Guarantor will remain bound under this Article X notwithstanding any extension
or renewal of any Obligation.

         Each Subsidiary Guarantor waives presentation to, demand of, payment
from and protest to the Company of any of the Obligations and also waives notice
of protest for nonpayment. Subject to Article XI, each Subsidiary Guarantor
waives notice of any default under the Securities or the Obligations. The
obligations of each Subsidiary Guarantor hereunder shall not be affected by (a)
the failure of any Holder or the Trustee to assert any claim or demand or to
enforce any right or remedy against the Company or any other Person under this
Indenture, the Securities or any other agreement or otherwise; (b) any extension
or renewal of any thereof; (c) any rescission, waiver, amendment or modification
of any of the terms or provisions of this Indenture, the Securities or any other
agreement; (d) the release of any security held by any Holder or the Trustee for
the Obligations or any of them; (e) the failure of any Holder or the Trustee to
exercise any right or remedy against any other guarantor of the Obligations; or
(f) any change in the ownership of such Subsidiary Guarantor.

         Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty
herein constitutes a guarantee of payment, performance and compliance when due
(and not a guarantee of collection) and waives any right to require that any
resort be had by any Holder or the Trustee to any security held for payment of
the Obligations.

         Each Subsidiary Guaranty is, to the extent and in the manner set forth
in Article XI, subordinated and subject in right of payment to the prior payment
in full of all Designated Senior Debt of the Subsidiary Guarantor giving such
Subsidiary Guaranty and is made subject to such provisions of this Indenture.

         Except as expressly set forth in Sections 4.06, 5.02 and 8.01(b), the
obligations of each Subsidiary Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Guaranteed Obligations or otherwise. Without limiting the generality of the
foregoing, the obligations of each Subsidiary Guarantor herein shall not be
discharged or impaired or otherwise affected by the failure of any Holder or the
Trustee to assert any claim or demand or to enforce any remedy under this
Indenture, the Securities or any other agreement, by any waiver or modification
of any thereof, by any default, failure or delay in the performance of the
obligations, or by any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of
such Subsidiary Guarantor or would otherwise operate as a discharge of such
Subsidiary Guarantor as a matter of law or

                                       62

<PAGE>

equity, except for any gross negligence, wilful misconduct or bad faith by such
Holder or the Trustee.

         Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty
herein shall continue to be effective or be reinstated, as the case may be, if
at any time payment, or any part thereof, of principal of or premium, if any, or
interest on any Obligation is rescinded or must otherwise be restored by any
Holder or the Trustee upon the bankruptcy or reorganization of the Company or
otherwise.

         In furtherance of the foregoing and not in limitation of any other
right that any Holder or the Trustee has at law or in equity against any
Subsidiary Guarantor by virtue hereof, and subject in all instances to Article
XI hereof, upon the failure of the Company to pay the principal of or premium,
if any, or interest on any Obligation when and as the same shall become due,
whether at maturity, by acceleration, by redemption or otherwise, or to perform
or comply with any other Obligation, each Subsidiary Guarantor hereby promises
to and will, upon receipt of written demand by the Trustee, forthwith pay, or
cause to be paid, in cash, to the Holders or the Trustee an amount equal to the
sum of (i) the unpaid amount of such Obligations, (ii) accrued and unpaid
premium, if any, and interest on such Obligations (but only to the extent not
prohibited by law), and (iii) all other monetary Obligations of the Company to
the Holders and the Trustee.

         Each Subsidiary Guarantor agrees that it shall not be entitled to any
right of subrogation in respect of any Obligations guaranteed hereby until
payment in full in cash of all Obligations and all obligations to which the
Obligations are subordinated as provided in Article XI. Each Subsidiary
Guarantor further agrees that, as between it, on the one hand, and the Holders
and the Trustee, on the other hand, (x) the maturity of the Obligations
guaranteed hereby may be accelerated as provided in Article VI for the purposes
of such Subsidiary Guarantor's Subsidiary Guaranty herein, notwithstanding any
stay, injunction or other prohibition preventing such acceleration in respect of
the Obligations guaranteed hereby, and (y) in the event of any declaration of
acceleration of such Obligations as provided in Article VI, such Obligations
(whether or not due and payable) shall, subject to Article XI hereof, forthwith
become due and payable by such Subsidiary Guarantor for the purposes of this
Section 10.01.

         Each Subsidiary Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or any
Holder in enforcing any rights under this Section 10.01.

         SECTION 10.02. Contribution. Each of the Company and any Subsidiary
Guarantor (a "Contributing Party") agrees (subject to Article XI) that, in the
event a payment shall be made by any other Subsidiary Guarantor under any
Subsidiary Guaranty (the "Claiming Guarantor"), the Contributing Party shall
indemnify the Claiming Guarantor in an amount equal to the amount of such
payment multiplied by a fraction, the numerator of which shall be the net worth
of the Contributing Party on the date hereof and the denominator of which shall
be the aggregate net worth of the Company and all the Subsidiary Guarantors on
the date hereof (or, in the case of any Subsidiary Guarantor becoming a party
hereto pursuant to Section 9.01, the date of the supplemental indenture executed
and delivered by such Subsidiary Guarantor).

         SECTION 10.03. Successors and Assigns. This Article X shall be binding
upon each Subsidiary Guarantor and its successors and assigns and shall inure to
the benefit of the successors and assigns of the Trustee and the Holders and, in
the event of any transfer or assignment of rights by any Holder or the Trustee,
the rights and privileges conferred upon that party in this Indenture and in the
Securities shall

                                       63

<PAGE>

automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions of this Indenture.

         SECTION 10.04. No Waiver. Neither a failure nor a delay on the part of
either the Trustee or the Holders in exercising any right, power or privilege
under this Article X shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits that either may have under this Article X at law,
in equity, by statute or otherwise.

         SECTION 10.05. Modification. No modification, amendment or waiver of
any provision of this Article X, nor the consent to any departure by any
Subsidiary Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Trustee, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. No notice to or demand on any Subsidiary Guarantor in any case shall
entitle such Subsidiary Guarantor to any other or further notice or demand in
the same, similar or other circumstances.

         SECTION 10.06. Execution of Supplemental Indenture for Future
Subsidiary Guarantors. Each Subsidiary that is required to become a Subsidiary
Guarantor pursuant to Section 4.15 shall promptly execute and deliver to the
Trustee a supplemental indenture in the form of Appendix B hereto pursuant to
which such Subsidiary shall become a Subsidiary Guarantor under this Article X
and shall guarantee the Obligations subject in all respects to Article XI
hereof. Concurrently with the execution and delivery of such supplemental
indenture, the Company shall deliver to the Trustee an Opinion of Counsel to the
effect that such supplemental indenture has been duly authorized, executed and
delivered by such Subsidiary and that, subject to the application of bankruptcy,
insolvency, moratorium, fraudulent conveyance or transfer and other similar laws
relating to creditors' rights generally and to the principles of equity, whether
considered in a proceeding at law or in equity, the Subsidiary Guaranty of such
Subsidiary Guarantor is a legal, valid and binding obligation of such Subsidiary
Guarantor, enforceable against such Subsidiary Guarantor in accordance with its
terms.

                                   ARTICLE XI

                     Subordination of Subsidiary Guarantees

         SECTION 11.01. Agreement To Subordinate. Each Subsidiary Guarantor
agrees, and each Securityholder by accepting a Security agrees, that the
Obligations of such Subsidiary Guarantor are subordinated in right of payment,
to the extent and in the manner provided in this Article XI, to the payment when
due of all Designated Senior Debt of such Subsidiary Guarantor and that the
subordination is for the benefit of and enforceable by the holders of such
Designated Senior Debt. Subject to the foregoing, the Obligations of each
Subsidiary Guarantor shall in all respects rank pari passu with all existing and
future Senior Debt of such Subsidiary Guarantor and senior to all existing and
future subordinated Debt of such Subsidiary Guarantor, and only Designated
Senior Debt shall rank senior to the Obligations of such Subsidiary Guarantor in
accordance with the provisions set forth herein.

         SECTION 11.02. Liquidation, Dissolution, Bankruptcy. Upon any payment
or distribution of the assets of any Subsidiary Guarantor to creditors upon a
total or partial liquidation or a total or partial dissolution of such
Subsidiary Guarantor or in a

                                       64

<PAGE>

bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to such Subsidiary Guarantor or its property:

         (1) holders of Designated Senior Debt of such Subsidiary Guarantor
    shall be entitled to receive payment in full in cash of such Designated
    Senior Debt before Securityholders shall be entitled to receive any payment
    pursuant to any Obligations of such Subsidiary Guarantor; and

         (2) until the Designated Senior Debt of any Subsidiary Guarantor is
    paid in full in cash, any distribution made by or on behalf of such
    Subsidiary Guarantor to which Securityholders would be entitled but for this
    Article XI shall be made to holders of the Designated Senior Debt as their
    interests may appear, except that all Securityholders may receive and retain
    shares of stock and any debt securities of such Subsidiary Guarantor that
    are subordinated to Designated Senior Debt of such Subsidiary Guarantor to
    at least the same extent as the Obligations of such Subsidiary Guarantor are
    subordinated to Designated Senior Debt of such Subsidiary Guarantor.

         SECTION 11.03. Default on Designated Senior Debt of Subsidiary
Guarantor. No Subsidiary Guarantor may make any payment pursuant to any of its
Obligations or repurchase, redeem or otherwise retire or defease any Securities
or other Obligations (collectively, "pay its Subsidiary Guaranty") if (i) any
principal, premium or interest in respect of the Designated Senior Debt of such
Subsidiary Guarantor is not paid when due (including at maturity), or (ii) any
other default on Designated Senior Debt of such Subsidiary Guarantor occurs and
the maturity of such Designated Senior Debt is accelerated in accordance with
its terms unless, in either case, (x) the default has been cured or waived and
any such acceleration has been rescinded, or (y) such Designated Senior Debt has
been paid in full in cash; provided, however, that any Subsidiary Guarantor may
pay its Subsidiary Guaranty without regard to the foregoing if such Subsidiary
Guarantor and the Trustee receive written notice approving such payment from the
holders of such Designated Senior Debt (or the authorized representative
therefor) of such Subsidiary Guarantor. In addition, during the continuance of
any default (other than a default described in clause (i) or (ii) of the
preceding sentence) with respect to any Designated Senior Debt pursuant to which
the maturity thereof may be accelerated immediately without further notice
(except any notice required to effect the acceleration) or the expiration of any
applicable grace period, no Subsidiary Guarantor may pay its Subsidiary Guaranty
for a period (a "Payment Blockage Period") commencing upon the receipt by such
Subsidiary Guarantor and the Trustee of written notice of such default from a
representative under such Designated Senior Debt specifying an election to
effect a Payment Blockage Period (a "Payment Blockage Notice") and ending 179
days thereafter (unless such Payment Blockage Period is earlier terminated (a)
by written notice to the Trustee and such Subsidiary Guarantor from such
authorized representative or the holders of such Designated Senior Debt, (b)
because such default is no longer continuing, or (c) because all such Designated
Senior Debt has been repaid in full in cash). Unless the holders of such
Designated Senior Debt shall have accelerated the maturity of such Designated
Senior Debt and not rescinded such acceleration, any Subsidiary Guarantor may
(unless otherwise prohibited as described in Section 11.02 or the first or
second sentences of this paragraph) resume payments pursuant to its Subsidiary
Guaranty after such Payment Blockage Period. Not more than one Payment Blockage
Notice may be given in any consecutive 360-day period, irrespective of the
number of defaults during such period.

         SECTION 11.04. Demand for Payment. If a demand for payment is made on a
Subsidiary Guarantor pursuant to Article X, such Subsidiary Guarantor may not
pay its Subsidiary Guaranty, and neither the Trustee nor any Securityholder may
retain any such payment, until ten Business Days after the holders of Designated
Senior Debt (or

                                       65

<PAGE>

their authorized representative) receive notice of such demand and, thereafter,
may pay its Subsidiary Guaranty only if this Indenture otherwise permits payment
at that time.

         SECTION 11.05. When Distribution Must Be Paid Over. If a distribution
is made to the Trustee or any Securityholders that because of this Article XI
should not have been made to them, the Trustee or such Securityholders who
receive the distribution shall hold it in trust for holders of the Designated
Senior Debt and promptly pay it over to them or their authorized representative
as their interests may appear.

         SECTION 11.06. Subrogation. After all Designated Senior Debt of a
Subsidiary Guarantor is paid in full in cash and until the Securities are paid
in full in cash, Securityholders shall be subrogated to the rights of holders of
Designated Senior Debt to receive distributions applicable to Designated Senior
Debt. A distribution made under this Article XI to holders of such Designated
Senior Debt that otherwise would have been made to Securityholders is not, as
between the relevant Subsidiary Guarantor and Securityholders, a payment by such
Subsidiary Guarantor on such Designated Senior Debt.

         SECTION 11.07. Relative Rights. This Article XI defines the relative
rights of Securityholders and holders of Designated Senior Debt of a Subsidiary
Guarantor. Nothing in this Indenture shall:

         (1) impair, as between a Subsidiary Guarantor and Securityholders, the
    obligation of such Subsidiary Guarantor, which is absolute and
    unconditional, to pay the Obligations to the extent set forth in Article X
    or the relevant Subsidiary Guaranty; or

         (2) prevent the Trustee or any Securityholder from exercising its
    available remedies upon a default by such Subsidiary Guarantor under the
    Obligations, subject to the rights of holders of Designated Senior Debt of
    such Subsidiary Guarantor to receive distributions otherwise payable to
    Securityholders.

         SECTION 11.08. Subordination May Not Be Impaired by Subsidiary
Guarantor. No right of any holder of Designated Senior Debt of any Subsidiary
Guarantor to enforce the subordination of the Obligation of such Subsidiary
Guarantor shall be impaired by any act or failure to act by such Subsidiary
Guarantor or the Company or by any of their failure to comply with this
Indenture.

         SECTION 11.09. Rights of Trustee and Paying Agent. Notwithstanding
Section 11.03, the Trustee or Paying Agent may continue to make payments on any
Subsidiary Guaranty and shall not, absent gross negligence or bad faith, be
charged with knowledge of the existence of facts that would prohibit the making
of any such payments unless, not less than two Business Days prior to the date
of such payment, a Trust Officer receives written notice satisfactory to it that
payments may not be made under this Article XI. The Company, the relevant
Subsidiary Guarantor, the Registrar or co-registrar, the Paying Agent, an
authorized representative or a holder of Designated Senior Debt of any
Subsidiary Guarantor may give the notice; provided, however, that, if any
Designated Senior Debt of any Subsidiary Guarantor has an authorized
representative, only such authorized representative may give the notice.

         The Trustee in its individual or any other capacity may hold Designated
Senior Debt with the same rights it would have if it were not Trustee. The
Registrar and co-registrar and the Paying Agent may do the same with like
rights. The Trustee shall be entitled to all the rights set forth in this
Article XI with respect to any Designated Senior Debt of any Subsidiary
Guarantor that may at any time be held by it, to the same extent as

                                       66

<PAGE>

any other holder of Designated Senior Debt; and nothing in Article VII shall
deprive the Trustee of any of its rights as such holder. Nothing in this Article
XI shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 7.07.

         SECTION 11.10. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Designated Senior
Debt of any Subsidiary Guarantor, the distribution may be made and the notice
given to the authorized representative, if any, of such Designated Senior Debt.

         SECTION 11.11. Article XI Not To Prevent Events of Default Under a
Subsidiary Guaranty or Limit Right To Demand Payment. The failure to make a
payment pursuant to a Subsidiary Guaranty by reason of any provision in this
Article XI shall not be construed as preventing the occurrence of a default
under such Subsidiary Guaranty. Nothing in this Article XI shall have any effect
on the right of the Securityholders or the Trustee to make a demand for payment
on any Subsidiary Guarantor pursuant to Article X or the relevant Subsidiary
Guaranty.

         SECTION 11.12. Trustee Entitled To Rely. Upon any payment or
distribution pursuant to this Article XI, the Trustee and the Securityholders
shall be entitled to rely, except to the extent such reliance would constitute
gross negligence or bad faith, (i) upon any order or decree of a court of
competent jurisdiction in which any proceedings of the nature referred to in
Section 11.02 are pending, (ii) upon a certificate of the liquidating trustee or
agent or other Person making such payment or distribution to the Trustee or to
the Securityholders, or (iii) upon the authorized representative, if any, for
the holders of Designated Senior Debt of any Subsidiary Guarantor for the
purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Designated Senior Debt and other Debt of such
Subsidiary Guarantor, the amount thereof or payable thereon, the amount or
amounts paid or distributed thereon and all other facts pertinent thereto or to
this Article XI. In the event that the Trustee determines, in good faith, that
evidence is required with respect to the right of any Person as a holder of
Designated Senior Debt of any Subsidiary Guarantor to participate in any payment
or distribution pursuant to this Article XI, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of Designated Senior Debt of such Subsidiary Guarantor held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and other facts pertinent to the rights of such Person
under this Article XI, and, if such evidence is not furnished, the Trustee may
defer any payment to such Person pending judicial determination as to the right
of such Person to receive such payment. The provisions of Sections 7.01 and 7.02
shall be applicable to all actions or omissions of actions by the Trustee
pursuant to this Article XI. Notwithstanding anything to the contrary contained
in this Section 11.12, the provisions of this Section 11.12 shall not change,
modify or otherwise affect the rights of the holders of Designated Senior Debt.

         SECTION 11.13. Trustee To Effectuate Subordination. Each Securityholder
by accepting a Security authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the
subordination between the Securityholders and the holders of Designated Senior
Debt of any Subsidiary Guarantor as provided in this Article XI and appoints the
Trustee as attorney-in-fact for any and all such purposes.

         SECTION 11.14. Trustee Not Fiduciary for Holders of Designated Senior
Debt of Subsidiary Guarantor. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Designated Senior Debt of any Subsidiary
Guarantor and, absent gross negligence or bad faith, shall not be liable to any
such holders if it shall mistakenly pay over or distribute to Securityholders or
the Company or any other Person money or assets

                                       67

<PAGE>

to which any holders of such Designated Senior Debt shall be entitled by virtue
of this Article XI or otherwise.

         SECTION 11.15. Reliance by Holders of Designated Senior Debt on
Subordination Provisions. Each Securityholder by accepting a Security
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any
Designated Senior Debt of any Subsidiary Guarantor, whether such Designated
Senior Debt was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, or to continue to hold, such
Designated Senior Debt and such holder of Designated Senior Debt shall be deemed
conclusively to have relied on such subordination provisions in acquiring and
continuing to hold, or in continuing to hold, such Designated Senior Debt.

                                   ARTICLE XII

                                  Miscellaneous

         SECTION 12.01. Trust Indenture Act Controls. If any provision of this
Indenture limits, qualifies or conflicts with another provision that is required
to be included in this Indenture by the TIA, the required provision of the TIA
shall control.

         SECTION 12.02. Notices. Any notice or communication shall be in writing
and delivered in person or mailed by first-class mail or sent by facsimile (with
a hard copy delivered in person or by mail promptly thereafter) and addressed as

         Any notice or communication mailed to a Securityholder shall be mailed
to the Securityholder at the Securityholder's address as it appears on the
registration books of the Registrar and shall be sufficiently given if so mailed
within the time prescribed.

         Failure to mail a notice or communication to a Securityholder or any

above, it is duly given, whether or not the addressee receives it.

         SECTION 12.03. Communication by Holders with Other Holders.

taking any action under this Indenture, the Company shall furnish to the
Trustee:

direction, waiver or consent, Securities owned by the Company, any Subsidiary
Guarantor or by any Person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any Subsidiary
Guarantor shall be disregarded and deemed not to be outstanding, except that,
for the purpose of determining whether the Trustee shall be protected in relying
on any such direction, waiver or consent, only Securities that the Trustee knows
are so owned shall be so disregarded. Also, subject to the foregoing, only
Securities outstanding at the time shall be considered in any such
determination.

         SECTION 12.07. Rules by Trustee, Paying Agent and Registrar. The

              (x) to register the transfer of such Definitive Securities; or

              (y) to exchange such Definitive Securities for an equal principal
       amount of Definitive Securities of other authorized denominations,

the Registrar or co-registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met;
provided, however, that the Definitive Securities surrendered for transfer or
exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form reasonably satisfactory to the Company and the Registrar or any
co-registrar, duly executed by the Holder thereof or his attorney duly
authorized in writing.

              (b) Transfer and Exchange of Global Securities.

              (i) The transfer and exchange of Global Securities or beneficial
       interests therein shall be effected through the Depository, in accordance
       with this Indenture (including applicable restrictions on transfer set
       forth herein, if any) and the procedures of the Depository therefor. A
       transferor of a beneficial interest in a Global Security shall deliver a
       written order given in accordance with the Depository's procedures
       containing information regarding the participant account of the
       Depository to be credited with a beneficial interest in such Global
       Security or another Global Security and such account shall be credited in
       accordance with

                                        2

<PAGE>

       such order with a beneficial interest in the applicable Global Security
       and the account of the Person making the transfer shall be debited by an
       amount equal to the beneficial interest in the Global Security being
       transferred.

              (ii) If the proposed transfer is a transfer of a beneficial
       interest in one Global Security to a beneficial interest in another
       Global Security, the Registrar or co-registrar shall reflect on its books
       and records the date and an increase in the principal amount of the
       Global Security to which such interest is being transferred in an amount
       equal to the principal amount of the interest to be so transferred, and
       the Registrar or co-registrar shall reflect on its books and records the
       date and a corresponding decrease in the principal amount of the Global
       Security from which such interest is being transferred.

               (iii) Notwithstanding any other provisions of this Appendix A
       (other than the provisions set forth in Section 2.4), a Global Security
       may not be transferred as a whole except by the Depository to a nominee
       of the Depository or by a nominee of the Depository to the Depository or
       another nominee of the Depository or by the Depository or any such
       nominee to a successor Depository or a nominee of such successor
       Depository.

               (c) Cancellation or Adjustment of Global Security. At such time
as all beneficial interests in a Global Security have either been exchanged for
Definitive Securities, transferred, redeemed, repurchased or canceled, such
Global Security shall be returned by the Depository to the Trustee for
cancellation or retained and canceled by the Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Security is exchanged for
Definitive Securities, transferred in exchange for an interest in another Global
Security, redeemed, repurchased or canceled, the principal amount of Securities
represented by such Global Security shall be reduced and an adjustment shall be
made on the books and records of the Trustee (if it is then the Securities
Custodian for such Global Security) with respect to such Global Security, by the
Trustee or the Securities Custodian, to reflect such reduction.

               (d) Obligations with Respect to Transfers and Exchanges of
Securities.

               (i) To permit registrations of transfers and exchanges, the
       Company shall execute and the Trustee shall authenticate Definitive
       Securities and Global Securities at the Registrar's or any co-registrar's
       request.

               (ii) No service charge shall be made for any registration of
       transfer or exchange, but the Company may require payment of a sum
       sufficient to cover any transfer tax, assessments, or similar
       governmental charge payable in connection therewith (other than any such
       transfer taxes, assessments or similar governmental charge payable upon
       exchange or transfer pursuant to Sections 3.06, 4.07, 4.14 and 9.05 of
       the Indenture).

               (iii) Prior to the due presentation for registration of transfer
       of any Security, the Company, the Trustee, the Paying Agent or the
       Registrar or any co-registrar may deem and treat the person in whose name
       a Security is registered as the absolute owner of such Security for the
       purpose of receiving payment of principal of and interest on such
       Security and for all other purposes whatsoever, whether or not such
       Security is overdue, and none of the Company, the Trustee, the Paying
       Agent or the Registrar or any co-registrar shall be affected by notice to
       the contrary.

               (iv) The Company shall not be required to make and the Registrar
       or co- registrar need not register transfers or exchanges of Securities
       selected for redemption (except, in the case of Securities to be redeemed
       in part, the portion

                                        3

<PAGE>

       thereof not to be redeemed) or any Securities for a period of 15 days
       before a selection of Securities to be redeemed.

           (v) All Securities issued upon any transfer or exchange pursuant to
       the terms of this Indenture shall evidence the same debt and shall be
       entitled to the same benefits under this Indenture as the Securities
       surrendered upon such transfer or exchange.

               (e)  No Obligation of the Trustee.

               (i) The Trustee shall have no responsibility or obligation to any
       beneficial owner of a Global Security, a member of, or a participant in
       the Depository or any other Person with respect to the accuracy of the
       records of the Depository or its nominee or of any participant or member
       thereof, with respect to any ownership interest in the Securities or with
       respect to the delivery to any participant, member, beneficial owner or
       other Person (other than the Depository) of any notice (including any
       notice of redemption or repurchase) or the payment of any amount, under
       or with respect to such Securities. All notices and communications to be
       given to the Holders and all payments to be made to Holders under the
       Securities shall be given or made only to the registered Holders (which
       shall be the Depository or its nominee in the case of a Global Security).
       The rights of beneficial owners in any Global Security shall be exercised
       only through the Depository subject to the applicable rules and
       procedures of the Depository. The Trustee may rely and shall be fully
       protected in relying upon information furnished by the Depository with
       respect to its members, participants and any beneficial owners.

               (ii) The Trustee shall have no obligation or duty to monitor,
       determine or inquire as to compliance with any restrictions on transfer
       imposed under this Indenture or under applicable law with respect to any
       transfer of any interest in any Security (including any transfers between
       or among Depository participants, members or beneficial owners in any
       Global Security) other than to require delivery of such certificates and
       other documentation or evidence as are expressly required by, and to do
       so if and when expressly required by, the terms of this Indenture, and to
       examine the same to determine substantial compliance as to form with the
       express requirements hereof.

       2.4  Definitive Securities

               (a) A Global Security deposited with the Depository or with the
Trustee as Securities Custodian pursuant to Section 2.1 shall be transferred to
the beneficial owners thereof in the form of Definitive Securities in an
aggregate principal amount equal to the principal amount of such Global
Security, in exchange for such Global Security, only if such transfer complies
with Section 2.3 and (i) the Depository notifies the Company that it is
unwilling or unable to continue as a Depository for such Global Security or if
at any time the Depository ceases to be a "clearing agency" registered under the
Exchange Act, and a successor depository is not appointed by the Company within
90 days of such notice, or (ii) an Event of Default has occurred and is
continuing, or (iii) the Company, in its sole discretion, notifies the Trustee
in writing that it elects to cause the issuance of certificated Securities under
this Indenture.

               (b) Any Global Security that is transferable to the beneficial
owners thereof pursuant to this Section 2.4 shall be surrendered by the
Depository to the Trustee, to be so transferred, in whole or from time to time
in part, without charge, and the Trustee shall authenticate and deliver, upon
such transfer of each portion of such Global Security, an equal aggregate
principal amount of Definitive Securities of authorized denominations. Any
portion of a Global Security transferred pursuant to this Section 2.4 shall be
executed, authenticated and delivered only in denominations of $1,000 of
principal

                                        4

<PAGE>

amount and any integral multiple thereof and registered in such names as the
Depository shall direct.

               (c) Subject to the provisions of Section 2.4(b), the registered
Holder of a Global Security may grant proxies and otherwise authorize any
Person, including Agent Members and Persons that may hold interests through
Agent Members, to take any action which a Holder is entitled to take under this
Indenture or the Securities.

               (d) In the event of the occurrence of any of the events specified
in Section 2.4(a)(i), (ii) or (iii), the Company will promptly make available to
the Trustee a reasonable supply of Definitive Securities in fully registered
form without interest coupons.

                            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).

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

                                        1

<PAGE>

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 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.

                                        2

<PAGE>

6. Sinking Fund

         The Securities are not subject to any sinking fund.

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.

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

                                        3

<PAGE>

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 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
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 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

                                        4

<PAGE>

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.

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.

    secured Debt merely by virtue of its unsecured nature;

         (7) the accreted value of any noninterest bearing or other discount
    security at any date shall be the accreted value thereof that would be shown
    on a balance sheet of the issuer dated such date prepared in accordance with
    GAAP; and

         (8) the principal amount of any Preferred Stock shall be the greater of
    (i) the maximum liquidation value of such Preferred Stock, or (ii) the
    maximum mandatory redemption or mandatory repurchase price with respect to
    such Preferred Stock.

                                   ARTICLE II

                                 The Securities

         SECTION 2.01. Form and Dating. Provisions relating to the Securities
are set forth in Appendix A, which is hereby incorporated in and expressly made
part of this Indenture. The Securities and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit 1 to Appendix A,
which is hereby incorporated in and expressly made a part of this Indenture. The
Securities may have notations, legends or endorsements required by law, stock
exchange rule, agreements to which the Company is subject, if any, or usage,
provided that any such notation, legend or endorsement is in a form reasonably
acceptable to the Company. Each Security shall be dated the date of its
authentication. The terms of the Securities set forth in Exhibit 1 to Appendix A
are part of the terms of this Indenture.

                                       25
<PAGE>

         SECTION 2.02. Execution and Authentication. Two Officers shall sign the
Securities for the Company by manual or facsimile signature. The Company's seal
shall be impressed, affixed, imprinted or reproduced on the Securities and may
be in facsimile form.

         If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a written order of the Company in
the form of an Officers' Certificate for the authentication and delivery of such
Securities, and the Trustee in accordance with such written order of the Company
shall authenticate and deliver such Securities.

         A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

         The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate the Securities. Unless limited by the terms of
such appointment, an authenticating agent may authenticate Securities whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as any Registrar, Paying Agent or agent for service of notices and
demands.

         SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an
office or agency where Securities may be presented for registration of transfer
or for exchange (the "Registrar") and an office or agency where Securities may
be presented for payment (the "Paying Agent"). The Registrar shall keep a
register of the Securities and of their transfer and exchange. The Company may
have one or more co-registrars and one or more additional paying agents. The
term "Paying Agent" includes any additional paying agent.

         The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any of its domestically incorporated Wholly Owned Subsidiaries may
act as Paying Agent, Registrar, co-registrar or transfer agent.

         The Company initially appoints the Trustee as Registrar and Paying
Agent in connection with the Securities.

         SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to each due
date of the Accreted Value, premium, if any, and interest on any Security, the
Company shall deposit with the Paying Agent a sum sufficient to pay such
Accreted Value, premium, if any, and interest when so becoming due. The Company
shall require each Paying Agent (other than the Trustee) to agree in writing
that the Paying Agent shall hold in trust for the benefit of Securityholders or
the Trustee all money held by the Paying Agent for the payment of Accreted
Value, premium, if any, of and interest on the Securities and shall notify the
Trustee of any default by the Company in making any such payment. If the Company
or a Wholly Owned Subsidiary acts as Paying Agent, it shall segregate the money
held by it as Paying Agent and hold it as a separate trust fund. The

                                       26
<PAGE>

Company at any time may require a Paying Agent to pay all money held by it to
the Trustee and to account for any funds disbursed by the Paying Agent. Upon
complying with this Section 2.04, the Paying Agent shall have no further
liability for the money delivered to the Trustee.

         SECTION 2.05. Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall furnish to the Trustee, in writing at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders.

         SECTION 2.06. Replacement Securities. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that such
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies
any other reasonable requirements of the Trustee. If required by the Trustee or
the Company, such Holder shall furnish an indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss that any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.

         Every replacement Security is an additional obligation of the Company.

         SECTION 2.07. Outstanding Securities. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancellation and those described in this
Section as not outstanding. A Security does not cease to be outstanding because
the Company or an Affiliate of the Company holds the Security.

         If a Security is replaced pursuant to Section 2.06, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

         If the Paying Agent segregates and holds in trust, in accordance with
this Indenture, on a redemption date or maturity date money sufficient to pay
all Accreted Value, premium, if any, and interest payable on that date with
respect to the Securities (or portions thereof) to be redeemed or maturing, as
the case may be, then on and after that date such Securities (or portions
thereof) cease to be outstanding and interest on them ceases to accrete.

         SECTION 2.08. Temporary Securities. Until definitive Securities are
ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities and
deliver them in exchange for temporary Securities.

         SECTION 2.09. Cancellation. The Company at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel and
destroy (subject to the record retention requirements of the Exchange Act) all
Securities surrendered for registration of transfer, exchange, payment or
cancellation and deliver a certificate of

                                       27
<PAGE>

such destruction to the Company. The Company may not issue new Securities to
replace Securities it has redeemed, paid or delivered to the Trustee for
cancellation.

         SECTION 2.10. Defaulted Interest. If the Company defaults in a payment
of interest on the Securities, the Company shall pay the defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date
and the amount of defaulted interest to be paid.

         SECTION 2.11. CUSIP Numbers. The Company in issuing the Securities may
use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Holders; provided,
however, that neither the Company nor the Trustee shall have any responsibility
for any defect in the "CUSIP" number that appears on any Security, check, advice
of payment or redemption notice, and any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.

                                   ARTICLE III

                                   Redemption

         SECTION 3.01. Notices to Trustee. If the Company elects to redeem
Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date, the principal amount at maturity of
Securities to be redeemed and that such redemption is being made pursuant to
paragraph 5 of the Securities.

         The Company shall give each notice to the Trustee provided for in this
Section 3.01 at least 45 days before the redemption date unless the Trustee
consents to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption will comply with the conditions herein.

         SECTION 3.02. Selection of Securities To Be Redeemed. If fewer than all
the Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed pro rata or by lot or a method that complies with applicable legal and
securities exchange requirements, if any, and that the Trustee considers fair
and appropriate and in accordance with methods generally used at the time of
selection by fiduciaries in similar circumstances. The Trustee shall make the
selection from outstanding Securities not previously called for redemption. The
Trustee may select for redemption portions of the Accreted Value of Securities
that have denominations larger than $1,000. Securities and portions of them the
Trustee selects shall be in amounts of $1,000 or a whole multiple of $1,000.
Provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption. The Trustee shall notify
the Company promptly of the Securities or portions of Securities to be redeemed.

         SECTION 3.03. Notice of Redemption. At least 30 days but not more than
60 days before a redemption date of Securities, the Company shall mail a notice
of redemption by first-class mail to each Holder of Securities to be redeemed.

         The notice shall identify the Securities to be redeemed and shall
state:

                                       28
<PAGE>

         (1) the redemption date;

         (2) the redemption price;

         (3) the name and address of the Paying Agent;

         (4) that Securities called for redemption must be surrendered to the
    Paying Agent to collect the redemption price;

         (5) if fewer than all the outstanding Securities are to be redeemed,
    the identification and Accreted Value of the particular Securities to be
    redeemed;

         (6) that, unless the Company defaults in making such redemption
    payment, interest on Securities (or portion thereof) called for redemption
    ceases to accrete on and after the redemption date; and

         (7) that no representation is made as to the correctness or accuracy of
    the CUSIP number, if any, listed in such notice or printed on the
    Securities.

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with the information required by this
Section at least 45 days before the redemption date.

         SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption
is mailed, Securities called for redemption become due and payable on the
redemption date and at the redemption price stated in the notice. Upon surrender
to the Paying Agent, such Securities shall be paid at the redemption price
stated in the notice, plus accrued interest to the redemption date (subject to
the right of Holders of record on the relevant record date to receive interest
due on the related interest payment date that is on or prior to such redemption
date). Failure to give notice or any defect in the notice to any Holder shall
not affect the validity of the notice to any other Holder.

         SECTION 3.05. Deposit of Redemption Price. Prior to the redemption
date, the Company shall deposit with the Paying Agent (or, if the Company or a
Wholly Owned Subsidiary is the Paying Agent, shall segregate and hold in trust)
money sufficient to pay the redemption price of and accrued interest (subject to
the right of Holders of record on the relevant record date to receive interest
due on the related interest payment date that is on or prior to the date of
redemption) on all Securities to be redeemed on that date other than Securities
or portions of Securities called for redemption that have been delivered by the
Company to the Trustee for cancellation.

         SECTION 3.06. Securities Redeemed in Part. Upon surrender of a Security
that is redeemed in part, the Company shall execute and the Trustee shall
authenticate for the Holder (at the Company's expense) a new Security equal in
Accreted Value to the unredeemed portion of the Security surrendered.

                                   ARTICLE IV

                                    Covenants

         SECTION 4.01. Payment of Securities. The Company shall promptly pay the
Accreted Value of, premium, if any, and interest on the Securities on the dates
and in the manner provided in the Securities and in this Indenture. Accreted
Value, premium, if any, and interest shall be considered paid on the date due if
on such date the Trustee or

                                       29
<PAGE>

the Paying Agent holds in accordance with this Indenture money sufficient to pay
all Accreted Value, premium, if any, and interest then due.

         The Company shall pay interest on overdue Accreted Value at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the rate borne by the Securities to the extent
lawful.

         SECTION 4.02. Commission Reports. Notwithstanding that the Company may
not be subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act, the Company shall file with the Commission and provide the Trustee
and holders of Securities with such annual reports and such information,
documents and other reports as are specified in Sections 13 and 15(d) of the
Exchange Act and applicable to a U.S. corporation subject to such Sections of
the Exchange Act, such information, documents and reports to be so filed and
provided at the times specified for the filing of such information, documents
and reports under such Sections; provided, however, that the Company shall not
be so obligated to file such information, documents and reports with the
Commission if the Commission does not permit such filings. The Company shall
also comply with the other provisions of TIA ss. 314(a).

         SECTION 4.03. Limitation on Debt. The Company shall not, and shall not
permit any Restricted Subsidiary to, Incur, directly or indirectly, any Debt
unless, after giving effect to the application of the proceeds thereof, no
Default or Event of Default would occur as a consequence of such Incurrence or
be continuing following such Incurrence and:

         (1) such Debt is Debt of the Company or a Subsidiary Guarantor and
    after giving effect to the Incurrence of such Debt and the application of
    the proceeds thereof, the Leverage Ratio of the Company and the Restricted
    Subsidiaries (calculated on a consolidated basis using Annualized Pro Forma
    EBITDA which gives pro forma effect to those Asset Sales, Investments or
    acquisitions of Property described in the definition of Pro Forma EBITDA)
    would not exceed 6.5 to 1.0; or

         (2) such Debt is Permitted Debt.

         The term "Permitted Debt" is defined to include obligations which meet
the requirements of any of the following clauses (a) through (j):

         (a) Debt of the Company evidenced by the Securities, the Senior Notes,
    and the Existing Notes, and of Subsidiary Guarantors evidenced by Subsidiary
    Guarantees relating to the Securities, the Senior Notes and the Existing
    Notes;

         (b) Debt of the Company or a Subsidiary Guarantor under any Credit
    Facilities, provided, however, that the aggregate principal amount of all
    such Debt under Credit Facilities at any one time outstanding shall not
    exceed an amount equal to $330.0 million, which amount shall be permanently
    reduced by the amount of Net Available Cash used to Repay Debt under the
    Credit Facilities and not subsequently reinvested in Additional Assets or
    used to purchase Securities or Repay other Debt, pursuant to Section 4.07;

         (c) Debt in respect of Capital Lease Obligations and Purchase Money
    Debt, provided, however, that:

              (1) the aggregate principal amount of such Debt does not exceed
         the Fair Market Value (on the date of the Incurrence thereof) of the
         Property acquired, constructed or leased, and

                                       30
<PAGE>

              (2) the aggregate principal amount of all Debt Incurred and then
         outstanding pursuant to this clause (c) (together with all Permitted
         Refinancing Debt Incurred and then outstanding in respect of Debt
         previously Incurred pursuant to this clause (c)) does not exceed $50.0
         million;

         (d) Debt of the Company owing to and held by any Restricted Subsidiary
    and Debt of a Restricted Subsidiary owing to and held by the Company or any
    Restricted Subsidiary; provided, however, that (i) if the Company or any
    Subsidiary Guarantor is the obligor on such Debt and the payee is not the
    Company or a Subsidiary Guarantor, such Debt must be expressly subordinated
    to the prior payment in full in cash of all obligations then due with
    respect to the Securities, in the case of the Company, or Subsidiary
    Guarantee, in the case of a Subsidiary Guarantor, and (ii) any subsequent
    issue or transfer of Capital Stock or other event that results in any such
    Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
    subsequent transfer of any such Debt (except to the Company or another
    Restricted Subsidiary) shall be deemed, in each case, to constitute the
    Incurrence of such Debt by the issuer thereof;

         (e) Debt under Interest Rate Agreements entered into by the Company or
    a Restricted Subsidiary for the purpose of limiting interest rate risk in
    the ordinary course of the financial management of the Company or such
    Restricted Subsidiary and not for speculative purposes, provided, however,
    that the obligations under such agreements are related to payment
    obligations on Debt otherwise permitted by the terms of this Section 4.03;

         (f) Debt in connection with one or more standby letters of credit or
    performance bonds issued by the Company or a Restricted Subsidiary in the
    ordinary course of business or pursuant to self-insurance obligations and
    not in connection with the borrowing of money or the obtaining of advances
    or credit;

         (g) Debt outstanding on the Issue Date not otherwise described in
    clauses (a) through (f) above;

         (h) Permitted Refinancing Debt Incurred in respect of Debt Incurred
    pursuant to clause (1) of the first paragraph of this Section 4.03 or clause
    (a), (c) or (g) above or clause (j) below;

         (i) additional Debt of the Company in an aggregate principal amount
    outstanding at any one time not to exceed $75.0 million; and

         (j) Acquired Debt Incurred by a Subsidiary Guarantor at the time a
    Sprint PCS Affiliate is merged with or into or becomes a Subsidiary of or
    transfers all or substantially all of its assets to such Subsidiary
    Guarantor on or prior to January 1, 2005, but only to the extent that
    immediately after giving effect to the Incurrence of such Debt (i) the
    Leverage Ratio would not exceed 7.75 to 1.0; and (ii) the Leverage Ratio
    immediately following such Incurrence would decrease as compared to the
    Leverage Ratio immediately prior to such Incurrence.

         For purposes of determining compliance with this Section 4.03,

         (a) in the event that any Debt is allowed to be Incurred pursuant to
    more than one of the categories of Debt described above, including clause
    (1) of the first paragraph of this Section 4.03 or as Permitted Debt, the
    Company, in its sole discretion, will classify such Debt, as of the time of
    Incurrence thereof, as Debt incurred pursuant to a particular clause under
    the first paragraph of this

                                       31
<PAGE>

    Section 4.03, and if Incurred as Permitted Debt will specify under which
    clause of Permitted Debt the Debt is Incurred; and

         (b) Debt may be divided and classified in more than one of the
    categories of Debt described above.

         Notwithstanding anything to the contrary contained in this Section
    4.03,

         (a) the Company shall not, and shall not permit any Subsidiary
    Guarantor to, Incur any Debt pursuant to this Section 4.03 if the proceeds
    thereof are used, directly or indirectly, to Refinance any Subordinated
    Obligations unless such Debt shall be subordinated to the Securities or the
    applicable Subsidiary Guaranty, as the case may be, to at least the same
    extent as such Subordinated Obligations, and

         (b) the Company shall not permit any Restricted Subsidiary that is not
    a Subsidiary Guarantor to Incur any Debt pursuant to this Section 4.03 if
    the proceeds thereof are used, directly or indirectly, to Refinance any Debt
    of the Company or any Subsidiary Guarantor.

         SECTION 4.04. Limitation on Restricted Payments. The Company shall not
make, and shall not permit any Restricted Subsidiary to make, directly or
indirectly, any Restricted Payment if at the time of, and after giving effect
to, such proposed Restricted Payment,

         (a) a Default or Event of Default shall have occurred and be
    continuing,

         (b) the Company could not Incur at least $1.00 of additional Debt
    pursuant to clause (1) of the first paragraph of Section 4.03, or

         (c) the aggregate amount of such Restricted Payment and all other
    Restricted Payments declared or made since the Issue Date (the amount of any
    Restricted Payment, if made other than in cash, to be based upon Fair Market
    Value) would exceed an amount equal to the sum of:

              (1) the result of:

                   (A) Cumulative EBITDA, minus

                   (B) the product of 1.5 and Cumulative Interest Expense, plus

              (2) Capital Stock Sale Proceeds, plus

              (3) the aggregate net cash proceeds received by the Company or any
         Restricted Subsidiary from the issuance or sale after the Issue Date of
         convertible or exchangeable Debt that has been converted into or
         exchanged for Capital Stock (other than Disqualified Stock) of the
         Company or any direct or indirect parent holding company of the
         Company, excluding (x) any such Debt issued or sold to the Company or a
         Subsidiary of the Company or an employee stock ownership plan or trust
         established by the Company or any such Subsidiary for the benefit of
         their employees, and (y) the aggregate amount of any cash or other
         Property distributed by the Company or any Restricted Subsidiary upon
         any such conversion or exchange, plus

              (4) an amount equal to the sum of:

                                       32
<PAGE>

                   (A) the net reduction in Investments in any Person other than
              the Company or a Restricted Subsidiary resulting from dividends,
              repayments of loans or advances or other transfers of Property, in
              each case to the Company or any Restricted Subsidiary from such
              Person, less the cost of the disposition of such Investment, plus

                   (B) the portion (proportionate to the Company's equity
              interest in such Unrestricted Subsidiary) of the Fair Market Value
              of the net assets of an Unrestricted Subsidiary at the time such
              Unrestricted Subsidiary is designated a Restricted Subsidiary;

provided, however, that the sum in this clause (4) shall not exceed, in the case
of any Person, the amount of Investments previously made (and treated as a
Restricted Payment) by the Company or any Restricted Subsidiary in such Person.

         Notwithstanding the foregoing limitation, the Company may take any
action if it is in compliance with any of the following clauses (a) through (h):

         (a) pay dividends on its Capital Stock within 60 days of the
    declaration thereof if, on such declaration date, such dividends could have
    been paid in compliance with this Indenture; provided, however, that at the
    time of such payment of such dividend, no other Default or Event of Default
    shall have occurred and be continuing (or result therefrom); provided
    further, however, that such dividend shall be included in the calculation of
    the amount of Restricted Payments;

         (b) purchase, repurchase, redeem, legally defease, acquire or retire
    for value Capital Stock of the Company or Subordinated Obligations in
    exchange for, or out of the proceeds of the substantially concurrent sale

    than Capital Stock issued or sold to a Subsidiary of the Company or an
    employee stock ownership plan or trust established by the Company or any
    such Subsidiary for the benefit of their employees); provided, however,
    that:

              (1) such purchase, repurchase, redemption, legal defeasance,
         acquisition or retirement shall be excluded in the calculation of the
         amount of Restricted Payments, and

              (2) the Capital Stock Sale Proceeds from such exchange or sale
         shall be excluded from the calculation pursuant to clause (c)(2) above;

         (c) purchase, repurchase, redeem, legally defease, acquire or retire
    for value any Subordinated Obligations in exchange for, or out of the
    proceeds of the substantially concurrent sale of, Permitted Refinancing
    Debt; provided, however, that such purchase, repurchase, redemption, legal
    defeasance, acquisition or retirement shall be excluded in the calculation
    of the amount of Restricted Payments;

         (d) make a Restricted Payment, if at the time the Company or any
    Restricted Subsidiary first Incurred a commitment for such Restricted
    Payment, such Restricted Payment could have been made; provided, however,
    that all commitments Incurred and outstanding shall be treated as if such
    commitments were Restricted Payments expended by the Company or a Restricted
    Subsidiary at the time the commitments were Incurred, except that
    commitments Incurred and outstanding that are treated as a Restricted
    Payment expended by the Company or

                                       33
<PAGE>

    a Restricted Subsidiary and that are terminated shall no longer be treated
    as a Restricted Payment expended by the Company or a Restricted Subsidiary
    upon the termination of such commitment;

         (e) repurchase shares of, or options to purchase shares of, common
    stock of the Company or any of its Subsidiaries (or pay dividends on its
    Capital Stock for the purpose of enabling any direct or indirect parent
    company of the Company to repurchase shares of, or options to purchase
    shares of, its common stock) from current or former officers, directors or
    employees of the Company or any of its Subsidiaries or any direct or
    indirect parent holding company of the Company (or permitted transferees of
    such current or former officers, directors or employees), pursuant to the
    terms of agreements (including employment agreements) or plans (or
    amendments thereto) approved by the Board of Directors of the Company or
    such parent holding company under which such individuals purchase or sell,
    or are granted the option to purchase or sell, shares of such common stock;
    provided, however, that:

              (1) the aggregate amount of such repurchases (or such dividends
         made to facilitate such repurchases) shall not exceed $3.0 million in
         any calendar year, although any unused amount in any calendar year may
         be carried forward to one or more future calendar years, and

              (2) at the time of such repurchase (or such dividends made to
         facilitate such repurchases), no other Default or Event of Default
         shall have occurred and be continuing (or result therefrom);

    provided further, however, that such repurchases (or such dividends made to
    facilitate such repurchases) shall be included in the calculation of the
    amount of Restricted Payments;

         (f) make Investments in any Person, provided that the Fair Market Value
    thereof, measured on the date each such Investment was made or returned, as
    applicable, when taken together with all other Investments made pursuant to
    this clause (f), does not exceed the sum of $50.0 million, plus the
    aggregate amount of the net reduction in Investments in any Person made
    pursuant to this clause (f) on and after the Issue Date resulting from
    dividends, repayments of loans or other transfers of Property, in each case
    to the Company or any Restricted Subsidiary from such Person, except to the
    extent that any such net reduction amount is included in the amount
    calculated pursuant to clause (c) of the preceding paragraph or any other
    clause of this paragraph; provided, however, that at the time of such
    Investment, no other Default or Event of Default shall have occurred and be
    continuing (or result therefrom); provided further, however, that such
    Investment shall be included in the calculation of the amount of Restricted
    Payments;

         (g) make payments to any direct or indirect parent holding company of
    the Company for legal, audit and other expenses directly relating to the
    administration of such parent holding company, which payments do not exceed
    $2.0 million in any fiscal year; and

         (h) make direct or indirect payments to Alamosa Holdings, Inc.
    (together with any successor thereof, "Parent") in amounts necessary to
    enable Parent to make cash dividend payments with respect to either (i) the
    shares of Series B Convertible Preferred Stock issued by Parent pursuant to
    the Exchange Offers (or any securities issued in exchange therefor) or (ii)
    the shares of Series C Convertible Preferred Stock of Parent (or any
    securities issued in exchange

                                       34
<PAGE>

    therefor) issued by Parent as dividends on shares of either Series B
    Convertible Preferred Stock or Series C Convertible Preferred Stock.

         SECTION 4.05. Limitation on Liens. The Company shall not, and shall not
permit any Restricted Subsidiary to, directly or indirectly, Incur or suffer to
exist, any Lien, other than Permitted Liens, upon any of its Property (including
Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or
thereafter acquired, or any interest therein or any income or profits therefrom,
unless it has made or will make effective provision whereby the Securities or
the applicable Subsidiary Guaranty will be secured by such Lien equally and
ratably with (or prior to) all other Debt of the Company or any Restricted
Subsidiary secured by such Lien.

         SECTION 4.06. Limitation on Issuance or Sale of Capital Stock of
Restricted Subsidiaries. The Company shall not:

         (a) sell, pledge, hypothecate or otherwise dispose of any shares of
    Capital Stock of a Restricted Subsidiary, except pledges of Capital Stock
    which constitute Permitted Liens, or

         (b) permit any Restricted Subsidiary to, directly or indirectly, issue
    or sell or otherwise dispose of any shares of its Capital Stock,

other than, in the case of either (a) or (b):

         (1) directors' qualifying shares,

         (2) to the Company or a Restricted Subsidiary,

         (3) a disposition of Capital Stock of such Restricted Subsidiary where
    immediately after giving effect thereto, either such Restricted Subsidiary
    remains a Restricted Subsidiary or the Company and the Restricted
    Subsidiaries no longer own any Capital Stock of such entity, provided,
    however, that, in the case of this clause (3),

              (A) such issuance, sale or disposition is effected in compliance
         with Section 4.07, and

              (B) upon consummation of any such disposition which results in the
         Company and the Restricted Subsidiaries no longer owning any Capital
         Stock of an entity and execution and delivery of a supplemental
         indenture in form satisfactory to the Trustee, such entity shall be
         released from any Subsidiary Guaranty previously made by such entity,

         (4) the transfer, conveyance, sale or other disposition of shares
    required by applicable law or regulation,

         (5) Capital Stock issued and outstanding on the Issue Date,

         (6) Capital Stock of a Restricted Subsidiary issued and outstanding
    prior to the time that such Person becomes a Restricted Subsidiary so long
    as such Capital Stock was not issued in contemplation of such Person's
    becoming a Restricted Subsidiary or otherwise being acquired by the Company,
    or

         (7) an issuance of Preferred Stock of a Restricted Subsidiary (other
    than Preferred Stock convertible or exchangeable into common stock of any
    Restricted Subsidiary) otherwise permitted by this Indenture.

                                       35

         SECTION 4.07. Limitation on Asset Sales. The Company shall not, and
shall not permit any Restricted Subsidiary to, directly or indirectly,
consummate any Asset Sale unless:

         (a) the Company or such Restricted Subsidiary receives consideration at
    the time of such Asset Sale at least equal to the Fair Market Value of the
    Property subject to such Asset Sale;

         (b) at least 75% of the consideration paid to the Company or such
    Restricted Subsidiary in connection with such Asset Sale is in the form of
    cash or cash equivalents or Telecommunications Assets or the assumption by
    the purchaser of liabilities of the Company or any Restricted Subsidiary
    (other than liabilities that are by their terms subordinated to the
    Securities or the applicable Subsidiary Guaranty) as a result of which the
    Company and the Restricted Subsidiaries are no longer obligated with respect
    to such liabilities; and

         (c) the Company delivers an Officers' Certificate to the Trustee
    certifying that such Asset Sale complies with the foregoing clauses (a) and
    (b).

         The Net Available Cash (or any portion thereof) from Asset Sales may be
applied by the Company or a Restricted Subsidiary, to the extent the Company or
such Restricted Subsidiary elects (or is required by the terms of any Debt):

         (a) to Repay Senior Debt of the Company or any Subsidiary Guarantor
    (including the Senior Notes, the Existing Notes and the Securities), or Debt
    of any Restricted Subsidiary that is not a Subsidiary Guarantor (excluding,
    in any such case, any Debt owed to the Company or an Affiliate of the
    Company); or

         (b) to reinvest in Additional Assets (including by means of an
    Investment in Additional Assets by a Restricted Subsidiary with Net
    Available Cash received by the Company or another Restricted Subsidiary).

         Any Net Available Cash from an Asset Sale not applied in accordance
with the preceding paragraph within 360 days from the date of the receipt of
such Net Available Cash shall constitute "Excess Proceeds." When the aggregate
amount of Excess Proceeds exceeds $10.0 million (taking into account income
earned on such Excess Proceeds, if any), the Company will be required to make an
offer to purchase (the "Prepayment Offer") the Securities, which offer shall be
in the amount of the Allocable Excess Proceeds, on a pro rata basis according to
principal amount at maturity at a purchase price equal to 100% of the Accreted
Value thereof, plus accrued and unpaid interest, if any, to the purchase date
(subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date), in accordance with
the procedures (including prorating in the event of oversubscription) set forth
below. To the extent that any portion of the amount of Net Available Cash
remains after compliance with the preceding sentence and provided that all
Holders have been given the opportunity to tender their Securities for purchase
in accordance with this Section 4.07, the Company or such Restricted Subsidiary
may use such remaining amount for any purpose permitted by this Indenture and
the amount of Excess Proceeds will be reset to zero.

         The term "Allocable Excess Proceeds" will mean the product of:

         (a) the Excess Proceeds and

         (b) a fraction,

                                       36
<PAGE>

         (1) the numerator of which is the aggregate Accreted Value of the
    Securities outstanding on the date of the Prepayment Offer, and

         (2) the denominator of which is the sum of the aggregate Accreted Value
    of the Securities outstanding on the date of the Prepayment Offer and the
    aggregate principal amount (or if Incurred with original issue discount, the
    aggregate accreted value) of other Debt of the Company (including the
    Existing Notes and the Senior Notes) outstanding on the date of the
    Prepayment Offer that is pari passu in right of payment with the Securities
    and subject to terms and conditions in respect of Asset Sales similar in all
    material respects to this Section 4.07 and requiring the Company to make an
    offer to purchase such Debt at substantially the same time as the Prepayment
    Offer.

         (d)(1) Within five Business Days after the Company is obligated to make
a Prepayment Offer as described in the preceding paragraph, the Company shall
send a written notice, by first-class mail, to the Holders (with a copy to the
Trustee), accompanied by such information regarding the Company and its
Subsidiaries as the Company in good faith believes will enable such Holders to
make an informed decision with respect to such Prepayment Offer. Such notice
shall state, among other things, the purchase price and the purchase date (the
"Purchase Date"), which shall be, subject to any contrary requirements of
applicable law, a business day no earlier than 30 days nor later than 60 days
from the date such notice is mailed.

         (2) Not later than the date upon which written notice of a Prepayment
Offer is delivered to the Trustee as provided above, the Company shall deliver
to the Trustee an Officers' Certificate as to (i) the amount of the Prepayment
Offer (the "Offer Amount"), (ii) the allocation of the Net Available Cash from
the Asset Sales pursuant to which such Prepayment Offer is being made and (iii)
the compliance of such allocation with the provisions of the second paragraph of
this Section 4.07. On or before the Purchase Date, the Company shall also
irrevocably deposit with the Trustee or with the Paying Agent (or, if the
Company or a Wholly Owned Subsidiary is the Paying Agent, shall segregate and
hold in trust) in Temporary Cash Investments (other than in those enumerated in
clause (b) of the definition of Temporary Cash Investments), maturing on the
last day prior to the Purchase Date or on the Purchase Date if funds are
immediately available by open of business, an amount equal to the Offer Amount
to be held for payment in accordance with the provisions of this Section 4.07.
Upon the expiration of the period for which the Prepayment Offer remains open
(the "Offer Period"), the Company shall deliver to the Trustee for cancellation
the Securities or portions thereof that have been properly tendered to and are
to be accepted by the Company. The Trustee or the Paying Agent shall, on the
Purchase Date, mail or deliver payment to each tendering Holder in the amount of
the purchase price. In the event that the aggregate purchase price of the
Securities delivered by the Company to the Trustee is less than the Offer
Amount, the Trustee or the Paying Agent shall deliver the excess to the Company
immediately after the expiration of the Offer Period for application in
accordance with this Section 4.07.

         (3) Holders electing to have a Security purchased shall be required to
surrender the Security, with an appropriate form duly completed, to the Company
or its agent at the address specified in the notice at least three Business Days
prior to the Purchase Date. Holders shall be entitled to withdraw their election
if the Trustee or the Company receives not later than one Business Day prior to
the Purchase Date a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the Accreted Value of the Security that was
delivered for purchase by the Holder and a statement that such Holder is
withdrawing its election to have such Security purchased. If at the expiration
of the Offer Period the aggregate Accreted Value of Securities surrendered by

                                       37
<PAGE>

Holders exceeds the Offer Amount, the Company shall select the Securities to be
purchased on a pro rata basis for all Securities (with such adjustments as may
be deemed appropriate by the Company so that only Securities in denominations of
$1,000, or integral multiples thereof, shall be purchased). Holders whose
Securities are purchased only in part shall be issued new Securities equal in
Accreted Value to the unpurchased portion of the Securities surrendered.

         (4) At the time the Company delivers Securities to the Trustee that are
to be accepted for purchase, the Company shall also deliver an Officers'
Certificate stating that such Securities are to be accepted by the Company
pursuant to and in accordance with the terms of this Section 4.07. A Security
shall be deemed to have been accepted for purchase at the time the Trustee or
the Paying Agent mails or delivers payment therefor to the surrendering Holder.

         (e) The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section 4.07. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.07, the Company will
comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Section 4.07 by virtue
thereof.

         SECTION 4.08. Limitation on Restrictions on Distributions from
Restricted Subsidiaries. The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, create or otherwise cause or
suffer to exist any consensual restriction on the right of any Restricted
Subsidiary to:

         (a) pay dividends, in cash or otherwise, or make any other
    distributions on or in respect of its Capital Stock, or pay any Debt or
    other obligation owed, to the Company or any other Restricted Subsidiary,

         (b) make any loans or advances to the Company or any other Restricted
    Subsidiary, or

         (c) transfer any of its Property to the Company or any other Restricted
    Subsidiary.

The foregoing limitations will not apply:

         (1) with respect to clauses (a), (b) and (c), to restrictions:

              (A) contained in an agreement or instrument governing or relating
         to Debt contained in any Credit Facility outstanding pursuant to clause
         (b) of the definition of Permitted Debt in Section 4.03; provided,
         however, that:

                   (x) the provisions of any Credit Facilities with a Stated
              Maturity prior to the scheduled maturity date of the Securities
              must permit distributions to the Company for the sole purpose of,
              and in an amount sufficient to fund, the payment of interest when
              due as scheduled in respect of the Securities, and

                   (y) the provisions of any Credit Facilities with a Stated
              Maturity on or after the scheduled maturity date of the Securities
              must permit distributions to the Company for the sole purpose of,
              and in an amount sufficient to fund, the payment of principal at

                                       38
<PAGE>

              scheduled maturity and interest when due as scheduled in respect
              of the Securities

         (provided, in the case of both (x) and (y), that such payment is due or
         to become due within 30 days from the date of such distribution and the
         cash distributed is in fact utilized to meet such payment obligation),
         at a time, in the case of both (x) and (y), when there does not exist
         an event (or such distribution would not cause an event) which, with
         the passage of time or notice or both, would permit the lenders under
         any Credit Facility to declare all amounts thereunder due and payable;
         provided further, however, that such agreement or instrument may
         nevertheless contain customary financial covenants,

              (B) relating to Debt of a Restricted Subsidiary and existing at
         the time it became a Restricted Subsidiary if such restriction was not
         created in connection with or in anticipation of the transaction or
         series of transactions pursuant to which such Restricted Subsidiary
         became a Restricted Subsidiary or was acquired by the Company, or

              (C) that result from the Refinancing of Debt Incurred pursuant to
         an agreement referred to in clause (1)(A) or (B) above or in clause
         (2)(A) or (B) below, provided such restriction is not materially less
         favorable to the Holders than those under the agreement evidencing the
         Debt so Refinanced, and

         (2) with respect to clause (c) only, to restrictions:

              (A) relating to Debt that is permitted to be Incurred and secured
         without also securing the Securities or the applicable Subsidiary
         Guaranty pursuant to Sections 4.03 and 4.05 that limit the right of the
         debtor to dispose of the Property securing such Debt,

              (B) encumbering Property at the time such Property was acquired by
         the Company or any Restricted Subsidiary, so long as such restriction
         relates solely to the Property so acquired and was not created in
         connection with or in anticipation of such acquisition,

              (C) resulting from customary provisions restricting subletting or
         assignment of leases or licenses or customary provisions in other
         agreements that restrict assignment of such agreements or rights
         thereunder,

              (D) customarily contained in property sale agreements limiting the
         transfer of such Property pending the closing of such sale, or

              (E) customarily contained in Debt instruments limiting the sale of
         all or substantially all the assets of the obligor.

         SECTION 4.09. Limitation on Transactions with Affiliates. The Company
shall not, and shall not permit any Restricted Subsidiary to, directly or
indirectly, conduct any business or enter into or suffer to exist any
transaction or series of transactions (including the purchase, sale, transfer,
assignment, lease, conveyance or exchange of any Property or the rendering of
any service) with, or for the benefit of, any Affiliate of the Company (an
"Affiliate Transaction"), unless:

         (a) the terms of such Affiliate Transaction are:

                                       39
<PAGE>

              (1) set forth in writing, and

              (2) no less favorable to the Company or such Restricted
         Subsidiary, as the case may be, than those that could be obtained in a
         comparable arm's-length transaction with a Person that is not an
         Affiliate of the Company,

         (b) if such Affiliate Transaction involves aggregate payments or value
    in excess of $5.0 million, the Board of Directors (including a majority of
    the disinterested members of the Board of Directors) approves such Affiliate
    Transaction and, in its good faith judgment, believes that such Affiliate
    Transaction complies with clause (a)(2) of this paragraph, as evidenced by a
    Board Resolution promptly delivered to the Trustee, and

         (c) if such Affiliate Transaction involves aggregate payments or value
    in excess of $25.0 million, the Company obtains a written opinion from an
    Independent Financial Advisor to the effect that the consideration to be
    paid or received in connection with such Affiliate Transaction is fair, from
    a financial point of view, to the Company and the Restricted Subsidiaries,
    taken as a whole.

         Notwithstanding the foregoing limitation, the Company or any Restricted
Subsidiary may enter into or suffer to exist the following:

         (a) any transaction or series of transactions between the Company and
    one or more Restricted Subsidiaries or between two or more Restricted
    Subsidiaries, provided, however, that no more than 10% of the total voting
    power of the Voting Stock (on a fully diluted basis) of any such Restricted
    Subsidiary is owned by an Affiliate of the Company (other than a Restricted
    Subsidiary);

         (b) any Restricted Payment permitted to be made pursuant to Section
    4.04 or any Permitted Investment;

         (c) the payment of compensation (including amounts paid pursuant to
    employee benefit plans) and the provision of benefits for the personal
    services of officers, directors and employees of the Company or any of the
    Restricted Subsidiaries, so long as the Board of Directors in good faith
    shall have approved the terms thereof;

         (d) loans and advances to employees made in the ordinary course of
    business and consistent with the past practices of the Company or such
    Restricted Subsidiary, as the case may be, provided, however, that such
    loans and advances do not exceed $3.0 million in the aggregate at any one
    time outstanding; and

         (e) any transaction or series of transactions pursuant to any agreement
    in existence on the Issue Date, and any renewal, extension or replacement of
    such agreement on terms no less favorable to the Company and the Restricted
    Subsidiaries than the agreement in existence on the Issue Date.

         SECTION 4.10. Limitation on Layered Debt. The Company shall not permit
any Subsidiary Guarantor to Incur, directly or indirectly, any Debt that is
subordinate or junior in right of payment to any Senior Debt unless such debt is
expressly subordinated in right of payment to, or ranks pari passu with, the
Obligations under its Subsidiary Guaranty.

                                       40
<PAGE>

         SECTION 4.11. Designation of Restricted and Unrestricted Subsidiaries.
The Board of Directors may designate any Subsidiary of the Company to be an
Unrestricted Subsidiary if:

         (a) the Subsidiary to be so designated does not own any Capital Stock
    or Debt of, or own or hold any Lien on any Property of, the Company or any
    other Restricted Subsidiary,

         (b) either:

              (1) the Subsidiary to be so designated has total assets of $1,000
         or less, or

              (2) such designation is effective either immediately upon such
         entity becoming a Subsidiary of the Company or as of the date hereof,
         and

         (c) neither the Company nor any Restricted Subsidiary is directly or
    indirectly liable for any Debt that provides that the holder thereof may
    (with the passage of time or notice or both) declare a default thereon or
    cause the payment thereof to be accelerated or payable prior to its Stated
    Maturity upon the occurrence of a default with respect to any Debt, Lien or
    other obligation of the Subsidiary to be so designated (including any right
    to take enforcement action against the Subsidiary to be so designated).

Unless so designated as an Unrestricted Subsidiary, any Person that becomes a
Subsidiary of the Company will be classified as a Restricted Subsidiary;
provided, however, that such Subsidiary shall not be designated a Restricted
Subsidiary and shall be automatically classified as an Unrestricted Subsidiary
if either of the requirements set forth in clauses (x) and (y) of the third
immediately following paragraph will not be satisfied after giving pro forma
effect to such classification or if such Person is a Subsidiary of an
Unrestricted Subsidiary.

         In addition, neither the Company nor any Restricted Subsidiary shall
become directly or indirectly liable for any Debt that provides that the holder
thereof may (with the passage of time or notice or both) declare a default
thereon or cause the payment thereof to be accelerated or payable prior to its
Stated Maturity upon the occurrence of a default with respect to any Debt, Lien
or other obligation of any Unrestricted Subsidiary (including any right to take
enforcement action against such Unrestricted Subsidiary).

         Except as provided in the first sentence of the next preceding
paragraph, no Restricted Subsidiary may be redesignated as an Unrestricted
Subsidiary. Upon designation of a Restricted Subsidiary as an Unrestricted
Subsidiary in compliance with this Section 4.11, such Restricted Subsidiary
shall, by execution and delivery of a supplemental indenture in form
satisfactory to the Trustee, be released from any Subsidiary Guaranty previously
made by such Restricted Subsidiary.

         The Board of Directors may designate any Unrestricted Subsidiary to be
a Restricted Subsidiary if, immediately after giving pro forma effect to such
designation,

         (x) the Company could Incur at least $1.00 of additional Debt pursuant
    to clause (1) of the first paragraph of Section 4.03, and

         (y) no Default or Event of Default shall have occurred and be
    continuing or would result therefrom.

                                       41
<PAGE>

         Any such designation or redesignation by the Board of Directors will be
evidenced to the Trustee by filing with the Trustee a Board Resolution giving

    fiscal quarter of the Company's fiscal year, within 90 days after the end of
    such fiscal year).

         SECTION 4.12. Limitation on Sale and Leaseback Transactions. The
Company shall not, and shall not permit any Restricted Subsidiary to, enter into
any Sale and Leaseback Transaction with respect to any Property unless:

         (a) the Company or such Restricted Subsidiary would be entitled to:

              (1) Incur Debt in an amount equal to the Attributable Debt with

              (2) create a Lien on such Property securing such Attributable Debt
         without also securing the Securities or the applicable Subsidiary
         Guaranty pursuant to Section 4.05, and

all or any part of such Holder's Securities pursuant to the offer described
below (the "Change of Control Offer") at a purchase price (the "Change of
Control Purchase Price") equal to 101.0% of the Accreted Value thereof, plus
accrued and unpaid interest, if any, to the purchase date (subject to the right
of Holders of record on the relevant record date to receive interest due on the

         Within 30 days following any Change of Control, the Company shall

         (a) cause a notice of the Change of Control Offer to be sent at least
    once to the Dow Jones News Service or a similar business news service in the

    Holder of Securities, at such Holder's address appearing in the Security
    Register, a notice stating:

              (1) that a Change of Control Offer is being made pursuant to this
         Section 4.14 and that all Securities timely tendered will be accepted
         for payment;

<PAGE>

              (2) the Change of Control Purchase Price and the purchase date,
         which shall be, subject to any contrary requirements of applicable law,
         a Business Day no earlier than 30 days nor later than 60 days from the
         date such notice is mailed (the "Change of Control Payment Date");

              (3) that any Security (or portion thereof) accepted for payment
         (and duly paid on the Change of Control Payment Date) pursuant to the
         Change of Control Offer shall cease to accrete interest after the
         Change of Control Payment Date;

              (4) that any Security (or portions thereof) not properly tendered
         will continue to accrete interest;

              (5) the circumstances and relevant facts regarding the Change of
         Control (including, if and to the extent material, information with
         respect to pro forma historical income, cash flow and capitalization
         after giving effect to the Change of Control); and

              (6) the procedures that Holders must follow in order to tender
         their Securities (or portions thereof) for payment and the procedures
         that Holders must follow in order to withdraw an election to tender
         Securities (or portions thereof) for payment.

         Holders electing to have a Security purchased shall be required to
surrender the Security, with an appropriate form duly completed, to the Company
or its agent at the address specified in the notice at least three Business Days
prior to the Change of Control Payment Date. Holders shall be entitled to
withdraw their election if the Trustee or the Company receives not later than
one Business Day prior to the Change of Control Payment Date a telegram, telex,
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of the Security that was delivered for purchase by the Holder
and a statement that such Holder is withdrawing its election to have such
Security purchased.

         On or prior to the Change of Control Payment Date, the Company shall
irrevocably deposit with the Trustee or with the Paying Agent (or, if the
Company or any of its Wholly Owned Subsidiaries is acting as the Paying Agent,
segregate and hold in trust) in cash an amount equal to the Change of Control
Purchase Price payable to the Holders entitled thereto, to be held for payment
in accordance with the provisions of this Section 4.14. On the Change of Control
Payment Date, the Company shall deliver to the Trustee the Securities or
portions thereof that have been properly tendered to and are to be accepted by
the Company for payment. The Trustee or the Paying Agent shall, on the Change of
Control Payment Date, mail or deliver payment to each tendering Holder of the
Change of Control Purchase Price. In the event that the aggregate Change of
Control Purchase Price is less than the amount delivered by the Company to the
Trustee or the Paying Agent, the Trustee or the Paying Agent, as the case may
be, shall deliver the excess to the Company immediately after the Change of
Control Payment Date.

         The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the purchase of Securities pursuant to this
Section 4.14. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Section 4.14, the Company will
comply with the applicable securities laws and regulations and will not be
deemed to have breached its obligations under this Section 4.14 by virtue
thereof.

    Officers' Certificate and an Opinion of Counsel, each stating that such
    transaction and the supplemental indenture, if any, in respect thereto

         (g) the Surviving Person shall have delivered to the Trustee an Opinion

    or series of transactions had not occurred.

         SECTION 5.02. When a Subsidiary Guarantor May Merge or Transfer Assets.
The Company shall not permit any Subsidiary Guarantor to merge, consolidate or
amalgamate with or into any other Person (other than a merger of a Wholly Owned

                                   ARTICLE VI

                              Defaults and Remedies

         SECTION 6.01. Events of Default. The following events shall be "Events
of Default":

         (1) the Company defaults in any payment of interest on any Security
    when the same becomes due and payable, and such default continues for a
    period of 30 days;

         (2) the Company defaults in the payment of Accreted Value of, or
    premium, if any, on, any Security when the same becomes due and payable at
    its Stated Maturity, upon acceleration, redemption, optional redemption,
    required repurchase or otherwise;

         (3) the Company or any Subsidiary Guarantor fails to comply with
    Article V;

         (4) the Company fails to comply with any covenant or agreement in the
    Securities or in this Indenture (other than a failure that is the subject of
    the foregoing clause (1), (2) or (3)) and such failure continues for 30 days
    after written notice is given to the Company as specified below;

         (5) a default by the Company or any Restricted Subsidiary under any
    Debt of the Company or any Restricted Subsidiary which results in
    acceleration of the maturity of such Debt, or the failure to pay any such
    Debt at maturity, in an aggregate amount in excess of $15.0 million;

         (6) the Company or any Significant Subsidiary pursuant to or within the
    meaning of any Bankruptcy Law:

              (A) commences a voluntary case;

              (B) consents to the entry of an order for relief against it in an
         involuntary case;

              (C) consents to the appointment of a Custodian of it or for any
         substantial part of its property; or

              (D) makes a general assignment for the benefit of its creditors;

    or takes any comparable action under any foreign laws relating to
    insolvency;

         (7) a court of competent jurisdiction enters an order or decree under
    any Bankruptcy Law that:

                                       47
<PAGE>

              (A) is for relief against the Company or any Significant
         Subsidiary in an involuntary case;

              (B) appoints a Custodian of the Company or any Significant
         Subsidiary or for any substantial part of its property; or

              (C) orders the winding up or liquidation of the Company or any
         Significant Subsidiary; or

              (D) grants any similar relief under any foreign laws;

    and in each such case the order or decree remains unstayed and in effect for
    30 days;

         (8) any judgment or judgments for the payment of money in an aggregate
    amount in excess of $15.0 million is entered against the Company or any
    Restricted Subsidiary and shall not be waived, satisfied or discharged for
    any period of 60 consecutive days during which a stay of enforcement shall
    not be in effect;

         (9) any Subsidiary Guaranty ceases to be in full force and effect
    (other than in accordance with the terms of this Indenture and such
    Subsidiary Guaranty) or any Subsidiary Guarantor denies or disaffirms its
    obligations under its Subsidiary Guaranty; or

         (10) any event occurs that causes, after giving effect to the
    expiration of any applicable grace period, an Event of Termination.

         The foregoing will constitute Events of Default whatever the reason for
any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

         The term "Bankruptcy Law" means Title 11, United States Code, or any
similar U.S. federal or state law for the relief of debtors. The term
"Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

         A Default under clause (4) is not an Event of Default until the Trustee
or the Holders of at least 25% in aggregate principal amount at maturity of the
Securities then outstanding notify the Company (and in the case of such notice
by Holders, the Trustee) of the Default and the Company does not cure such
Default within the time specified after receipt of such notice. Such notice must
specify the Default, demand that it be remedied and state that such notice is a
"Notice of Default".

         The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default and any event that with the giving of notice or the lapse
of time would become an Event of Default, its status and what action the Company
is taking or proposes to take with respect thereto.

         SECTION 6.02. Acceleration. If an Event of Default (other than an Event
of Default specified in Section 6.01(6) or (7) with respect to the Company)
occurs and is continuing, the Trustee by notice to the Company, or the Holders
of at least 25% in aggregate principal amount at maturity of the Securities then
outstanding by notice to the Company and the Trustee, may declare the Accreted
Value of and accrued and unpaid

                                       48
<PAGE>

interest on all the Securities to be due and payable. Upon such a declaration,
such Accreted Value and interest shall be due and payable immediately. If an
Event of Default specified in Section 6.01(6) or (7) with respect to the Company
occurs, the Accreted Value of and accrued and unpaid interest on all the
Securities shall, automatically and without any action by the Trustee or any
Holder, become and be immediately due and payable. The Holders of a majority in
aggregate principal amount at maturity of the outstanding Securities by notice
to the Trustee and the Company may rescind any declaration of acceleration 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. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

         SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of Accreted Value of or interest on the Securities or to enforce the performance
of any provision of the Securities or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

         SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in
aggregate principal amount at maturity of the Securities then outstanding by
notice to the Trustee may waive an existing Default and its consequences except
(i) a Default in the payment of the Accreted Value of or the premium, if any, or
interest on a Security, or (ii) a Default in respect of a provision that under
Section 9.02 cannot be amended without the consent of each Securityholder
affected. When a Default is waived, it is deemed cured, but no such waiver shall
extend to any subsequent or other Default or impair any consequent right.

         SECTION 6.05. Control by Majority. The Holders of a majority in
aggregate principal amount at maturity of the Securities then outstanding may
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or of exercising any trust or power conferred on the
Trustee with respect to the Securities. However, the Trustee may refuse to
follow any direction that conflicts with law or this Indenture or, subject to
Section 7.01, that the Trustee determines is unduly prejudicial to the rights of
other Securityholders or would involve the Trustee in personal liability;
provided, however, that the Trustee may take any other action deemed proper by
the Trustee that is not inconsistent with such direction. Prior to taking any
action hereunder, the Trustee shall be entitled to reasonable indemnification
against all losses and expenses caused by taking or not taking such action.

         SECTION 6.06. Limitation on Suits. A Securityholder may not pursue any
remedy with respect to this Indenture or the Securities unless:

         (1) such Holder shall have previously given to the Trustee written
    notice of a continuing Event of Default;

         (2) the Holders of at least 25% in aggregate principal amount at
    maturity of the Securities then outstanding shall have made a written
    request, and such Holder or Holders shall have offered reasonable indemnity
    to the Trustee to pursue such proceeding as trustee; and

                                       49
<PAGE>

         (3) the Trustee has failed to institute such proceeding and has not
    received from the Holders of at least a majority in aggregate principal
    amount at maturity of the Securities outstanding a direction inconsistent
    with such request, within 60 days after such notice, request and offer.

         The foregoing limitations on the pursuit of remedies by a
Securityholder shall not apply to a suit instituted by a Holder of Securities
for the enforcement of payment of the Accreted Value of or premium, if any, or
interest on such Security on or after the applicable due date specified in such
Security. A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over another
Securityholder.

         SECTION 6.07. Rights of Holders To Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
Accreted Value of and premium, if any, and interest on the Securities held by
such Holder, on or after the respective due dates expressed in the Securities,
or to bring suit for the enforcement of any such payment on or after such
respective dates, shall not be impaired or affected without the consent of such
Holder.

         SECTION 6.08. Collection Suit by Trustee. If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

         SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

         SECTION 6.10. Priorities. If the Trustee collects any money or property
pursuant to this Article VI, it shall pay out the money or property in the
following order:

         FIRST: to the Trustee for amounts due under Section 7.07;

         SECOND: to Securityholders for amounts due and unpaid on the Securities
    for Accreted Value, premium, if any, and interest, ratably, without
    preference or priority of any kind, according to the amounts due and payable
    on the Securities for Accreted Value, premium, if any, and interest,
    respectively; and

         THIRD: to the Company.

         The Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section. At least 15 days before such record
date, the Company shall mail to each Securityholder and the Trustee a notice
that states the record date, payment date and amount to be paid.

         SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action

                                       50
<PAGE>

taken or omitted by it as Trustee, a court in its discretion may require the
filing by any party litigant in the suit of an undertaking to pay the costs of
the suit, and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in
aggregate principal amount at maturity of the Securities.

         SECTION 6.12. Waiver of Stay or Extension Laws. The Company (to the
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution
of any power herein granted to the Trustee but shall suffer and permit the
execution of every such power as though no such law had been enacted.

                                   ARTICLE VII

                                     Trustee

         SECTION 7.01. Duties of Trustee. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

         (b) Except during the continuance of an Event of Default:

         (1) the Trustee undertakes to perform such duties and only such duties
    as are specifically set forth in this Indenture and no implied covenants or
    obligations shall be read into this Indenture against the Trustee; and

         (2) in the absence of bad faith on its part, the Trustee may
    conclusively rely, as to the truth of the statements and the correctness of
    the opinions expressed therein, upon certificates or opinions furnished to
    the Trustee and conforming to the requirements of this Indenture. However,
    the Trustee shall examine the certificates and opinions to determine whether
    or not they conform to the requirements of this Indenture.

         (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own wilful misconduct,
except that:

         (1) this paragraph does not limit the effect of paragraph (b) of this
    Section 7.01;

         (2) the Trustee shall not be liable for any error of judgment made in
    good faith by a Trust Officer unless it is proved that the Trustee was
    negligent in ascertaining the pertinent facts; and

         (3) the Trustee shall not be liable with respect to any action it takes
    or omits to take in good faith in accordance with a direction received by it
    pursuant to Section 6.05.

         (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01.

                                       51
<PAGE>

         (e) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Company.

         (f) Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

         (g) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur financial liability in the performance
of any of its duties hereunder or in the exercise of any of its rights or
powers.

         (h) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section 7.01 and to the provisions of the TIA
and the provisions of this Article VII shall apply to the Trustee in its role as
Registrar, Paying Agent and Custodian.

         (i) The Trustee shall not be deemed to have notice of a Default or an
Event of Default unless (a) the Trustee has received written notice thereof from
the Company or any Holder, or (b) a Trust Officer shall have actual knowledge
thereof.

         SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on any
document believed by it to be genuine and to have been signed or presented by
the proper person. The Trustee need not investigate any fact or matter stated in
the document. The Trustee may, however, in its discretion make such further
inquiry or investigation into such facts or matters as it may see fit and, if
the Trustee shall determine to make such further inquiry or investigation, it
shall be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney.

         (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable
for any action it takes or omits to take in good faith in reliance on the
Officers' Certificate or Opinion of Counsel.

         (c) The Trustee may act through agents and shall not be responsible for
the misconduct or negligence of any agent appointed with due care.

         (d) The Trustee shall not be liable for any action it takes or omits to
take in good faith that it believes to be authorized or within its rights or
powers; provided, however, that the Trustee's conduct does not constitute wilful
misconduct or negligence.

         (e) The Trustee may consult with counsel, and the advice or opinion of
counsel with respect to legal matters relating to this Indenture and the
Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

         (f) The permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty unless so specified herein.

         SECTION 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar or
co-registrar may do the same with like rights. However, the Trustee must comply
with Sections 7.10 and 7.11.

         SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity, priority or
adequacy of this

                                       52
<PAGE>

Indenture or the Securities, it shall not be accountable for the Company's use
of the proceeds from the Securities, and it shall not be responsible for any
statement of the Company or any Subsidiary Guarantor in this Indenture or in any
document issued in connection with the sale of the Securities or in the
Securities other than the Trustee's certificate of authentication.

         SECTION 7.05. Notice of Defaults. If a Default or Event of Default
occurs and is continuing and if it is known to the Trustee, the Trustee shall
mail to each Securityholder notice of the Default or Event of Default within 90
days after it is known to a Trust Officer or written notice of it is received by
the Trustee. Except in the case of a Default or Event of Default in payment of
Accreted Value of, premium, if any, or interest on any Security, the Trustee may
withhold the notice if and so long as a committee of its Trust Officers in good
faith determines that withholding the notice is in the interests of
Securityholders.

         SECTION 7.06. Reports by Trustee to Holders. As promptly as practicable
after each December 31 beginning with December 31, 2003, and in any event prior
to March 31 in each year, the Trustee shall mail to each Securityholder a brief
report dated as of December 31 each year that complies with TIA ss. 313(a), if
and to the extent required by such subsection. The Trustee shall also comply
with TIA ss. 313(b).

         A copy of each report at the time of its mailing to Securityholders
shall be filed with the Commission and each stock exchange (if any) on which the
Securities are listed. The Company agrees to notify promptly the Trustee
whenever the Securities become listed on any stock exchange and of any delisting
thereof.

         SECTION 7.07. Compensation and Indemnity. The Company shall pay to the
Trustee from time to time reasonable compensation for its services. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of- pocket expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts. The Company and each Subsidiary Guarantor, jointly and severally, shall
indemnify the Trustee against any and all loss, liability or expense (including
reasonable attorneys' fees) incurred by it in connection with the acceptance and
administration of this trust and the performance of its duties hereunder. The
Trustee shall notify the Company promptly of any claim for which it may seek
indemnity. Failure by the Trustee to so notify the Company shall not relieve the
Company or any Subsidiary Guarantor of its obligations hereunder. The Company
shall defend the claim and the Trustee may have separate counsel and the Company
and the Subsidiary Guarantors, as applicable, shall pay the fees and expenses of
such counsel. The Company need not reimburse any expense or indemnify against
any loss, liability or expense incurred by the Trustee through the Trustee's own
wilful misconduct, negligence or bad faith. The Company need not pay for any
settlement made by the Trustee without the Company's consent, such consent not
to be unreasonably withheld. All indemnifications and releases from liability
granted hereunder to the Trustee shall extend to its officers, directors,
employees, agents, successors and assigns.

         To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities.

         The Company's payment obligations pursuant to this Section 7.07 shall
survive the resignation or removal of the Trustee and the discharge of this
Indenture.

                                       53
<PAGE>

When the Trustee incurs expenses after the occurrence of a Default specified in
Section 6.01(6) or (7) with respect to the Company, the expenses are intended to
constitute expenses of administration under the Bankruptcy Law.

         SECTION 7.08. Replacement of Trustee. The Trustee may resign at any
time by so notifying the Company. The Holders of a majority in aggregate
principal amount at maturity of the Securities then outstanding may remove the
Trustee by so notifying the Trustee and may appoint a successor Trustee. The
Company shall remove the Trustee if:

         (1) the Trustee fails to comply with Section 7.10;

         (2) the Trustee is adjudged bankrupt or insolvent;

         (3) a receiver or other public officer takes charge of the Trustee or
its property; or

         (4) the Trustee otherwise becomes incapable of acting.

         If the Trustee resigns, is removed by the Company or by the Holders of
a majority in aggregate principal amount at maturity of the Securities then
outstanding and such Holders do not reasonably promptly appoint a successor
Trustee, or if a vacancy exists in the office of Trustee for any reason (the
Trustee in such event being referred to herein as the retiring Trustee), the
Company shall promptly appoint a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

         If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of
10% in aggregate principal amount at maturity of the Securities then outstanding
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

         If the Trustee fails to comply with Section 7.10, any Securityholder
who has been a bona fide Holder of a Security for at least six months may
petition any court of competent jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

         Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

         SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates
with, merges or converts into, or transfers all or substantially all its
corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation or banking
association without any further act shall be the successor Trustee.

         In case at the time such successor or successors by merger, conversion
or consolidation to the Trustee shall succeed to the trusts created by this
Indenture any of the Securities shall have been authenticated but not delivered,
any such successor to the

                                       54
<PAGE>

Trustee may adopt the certificate of authentication of any predecessor trustee,
and deliver such Securities so authenticated; and in case at that time any of
the Securities shall not have been authenticated, any such successor to the
Trustee may authenticate such Securities either in the name of any predecessor
hereunder or in the name of the successor to the Trustee; and in all such cases
such certificates shall have the full force which it is anywhere in the
Securities or in this Indenture provided that the certificate of the Trustee
shall have.

         SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all
times satisfy the requirements of TIA ss. 310(a). The Trustee shall have (or, in
the case of a corporation included in a bank holding company system, the related
bank holding company shall have) a combined capital and surplus of at least
$150.0 million as set forth in its (or its related bank holding company's) most
recent published annual report of condition. The Trustee shall comply with TIA
ss. 310(b), subject to the penultimate paragraph thereof; provided, however,
that there shall be excluded from the operation of TIA ss. 310(b)(1) any
indenture or indentures under which other securities or certificates of interest
or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in TIA ss. 310(b)(1) are met.

         SECTION 7.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA ss. 311(a), excluding any creditor relationship
listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be
subject to TIA ss. 311(a) to the extent indicated.

                                  ARTICLE VIII

                       Discharge of Indenture; Defeasance

         SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a)
When (i) the Company delivers to the Trustee all outstanding Securities (other
than Securities replaced pursuant to Section 2.06) for cancellation, or (ii) all
outstanding Securities have become due and payable, whether at maturity or as a
result of the mailing of a notice of redemption pursuant to Article III and the
Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities, including interest
thereon to maturity or such redemption date (other than Securities replaced
pursuant to Section 2.06), and if in either case the Company pays all other sums
payable hereunder by the Company, then this Indenture shall, subject to Section
8.01(c), cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company.

         (b) Subject to Sections 8.01(c) and 8.02, the Company at any time may
terminate (i) all of its obligations under the Securities and this Indenture
("legal defeasance option"), or (ii) its obligations under Sections 4.02, 4.03,
4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and 4.15 and
the operation of Sections 6.01(5), 6.01(6), 6.01(7), 6.01(8), 6.01(9) and
6.01(10) (but, in the case of Sections 6.01(6) and (7), with respect only to
Significant Subsidiaries) and the limitations contained in clause (e) of
Sections 5.01 and 5.02 ("covenant defeasance option"). The Company may exercise
its legal defeasance option notwithstanding its prior exercise of its covenant
defeasance option.

         If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default. If the Company
exercises its covenant defeasance option, payment of the Securities may not be
accelerated because of an Event of Default specified in Sections 6.01(4) (with
respect to

                                       55
<PAGE>

the covenants of Article IV identified in the immediately preceding paragraph),
6.01(5), 6.01(6), 6.01(7), 6.01(8), 6.01(9) and 6.01(10) (but, in the case of
Sections 6.01(6) and (7), with respect only to Significant Subsidiaries) or
because of the failure of the Company to comply with the limitations contained
in clause (e) of Sections 5.01 and 5.02. If the Company exercises its legal
defeasance option or its covenant defeasance option, each Subsidiary Guarantor,
if any, shall be released from all its obligations under its Subsidiary
Guarantee.

         Upon satisfaction of the conditions set forth herein and upon request
of the Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

         (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 7.07, 7.08, 8.05 and 8.06 shall
survive until the Securities have been paid in full. Thereafter, the Company's
obligations in Sections 7.07 and 8.05 shall survive.

         SECTION 8.02. Conditions to Defeasance. The Company may exercise its
legal defeasance option or its covenant defeasance option only if:

         (1) the Company irrevocably deposits in trust with the Trustee money or
    U.S. Government Obligations for the payment of Accreted Value of and
    premium, if any, and interest on the Securities to maturity or redemption,
    as the case may be;

         (2) the Company delivers to the Trustee a certificate from a nationally
    recognized firm of independent accountants expressing their opinion that the
    payments of Accreted Value, premium, if any, and interest when due and
    without reinvestment on the deposited U.S. Government Obligations plus any
    deposited money without investment will provide cash at such times and in
    such amounts as will be sufficient to pay the Accreted Value, premium, if
    any, and interest when due on all the Securities to maturity or redemption,
    as the case may be;

         (3) 123 days pass after the deposit is made and during the 123-day
    period no Default specified in Section 6.01(6) or (7) with respect to the
    Company occurs that is continuing at the end of the period;

         (4) no Default or Event of Default has occurred and is continuing on
    the date of such deposit and after giving effect thereto;

         (5) the deposit does not constitute a default under any other agreement
    or instrument binding on the Company;

         (6) the Company delivers to the Trustee an Opinion of Counsel to the
    effect that the trust resulting from the deposit does not constitute, or is
    qualified as, a regulated investment company under the Investment Company
    Act of 1940;

         (7) in the case of the legal defeasance option, the Company shall have
    delivered to the Trustee an Opinion of Counsel stating that (i) the Company
    has received from, or there has been published by, the Internal Revenue
    Service a ruling, or (ii) since the date of this Indenture there has been a
    change in the applicable U.S. federal income tax law, in either case to the
    effect that, and based thereon such Opinion of Counsel shall confirm that,
    the Securityholders will not recognize income, gain or loss for U.S. federal
    income tax purposes as a result of such defeasance and will be subject to
    U.S. federal income tax on the same

                                       56
<PAGE>

    amounts, in the same manner and at the same times as would have been the
    case if such defeasance had not occurred;

         (8) in the case of the covenant defeasance option, the Company shall
    have delivered to the Trustee an Opinion of Counsel to the effect that the
    Securityholders will not recognize income, gain or loss for U.S. federal
    income tax purposes as a result of such covenant defeasance and will be
    subject to U.S. federal income tax on the same amounts, in the same manner
    and at the same times as would have been the case if such covenant
    defeasance had not occurred; and

         (9) the Company delivers to the Trustee an Officers' Certificate and an
    Opinion of Counsel, each stating that all conditions precedent to the
    defeasance and discharge of the Securities as contemplated by this Article
    VIII have been complied with.

         Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article III.

         SECTION 8.03. Application of Trust Money. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to this
Article VIII. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of Accreted Value of and premium, if any, and interest
on the Securities.

         SECTION 8.04. Repayment to Company. The Trustee and the Paying Agent
shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

         Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon request any money held by them for
the payment of Accreted Value, premium, if any, or interest that remains
unclaimed for two years, and, thereafter, Securityholders entitled to the money
must look to the Company for payment as general creditors.

         SECTION 8.05. Indemnity for Government Obligations. The Company shall
pay and shall indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against deposited U.S. Government Obligations or the principal
and interest received on such U.S. Government Obligations.

         SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with this
Article VIII by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article VIII until such time as the
Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article VIII; provided, however, that, if
the Company has made any payment of interest on or Accreted Value of any
Securities because of the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Securities to receive such
payment from the money or U.S. Government Obligations held by the Trustee or
Paying Agent.

                                   ARTICLE IX

                                   Amendments

         SECTION 9.01. Without Consent of Holders. The Company, the Subsidiary
Guarantors and the Trustee may amend this Indenture or the Securities without
notice to or consent of any Securityholder:

         (1) to cure any ambiguity, omission, defect or inconsistency;

         (2) to comply with Article V;

         (3) to provide for uncertificated Securities in addition to or in place
    of certificated Securities; provided, however, that the uncertificated
    Securities are issued in registered form for purposes of Section 163(f) of
    the Code or in a manner such that the uncertificated Securities are
    described in Section 163(f)(2)(B) of the Code;

         (4) to make any change in Article XI that would limit or terminate the
    benefits available to any holder of Designated Senior Debt (or
    representatives therefor) under Article XI;

         (5) to add Guarantees with respect to the Securities, to secure the
    Securities or to release Subsidiary Guarantors from Subsidiary Guaranties as
    provided by the terms of this Indenture;

         (6) to add to the covenants of the Company for the benefit of the
    Holders or to surrender any right or power herein conferred upon the
    Company;

         (7) to comply with any requirements of the Commission in connection
    with qualifying, or maintaining the qualification of, this Indenture under
    the TIA; or

         (8) to make any change that does not adversely affect the rights of any
    Securityholder.

         An amendment under this Section may not make any change that adversely
affects the rights under Article X or XI of any holder of Designated Senior Debt
then outstanding unless the holders of such Designated Senior Debt (or their
authorized representatives) consent to such change.

         After an amendment under this Section 9.01 becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section 9.01.

         SECTION 9.02. With Consent of Holders. The Company, the Subsidiary
Guarantors and the Trustee may amend this Indenture or the Securities without
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 Securities
then outstanding (including consents obtained in connection with a tender offer
or exchange offer for the Securities). However, without the consent of each
Securityholder affected thereby, an amendment may not:

         (1) reduce the amount of Securities whose Holders must consent to an
    amendment or waiver;

                                       58
<PAGE>

         (2) reduce the rate of or extend the time for payment of interest on
    any Security;

         (3) reduce the Accreted Value of or extend the Stated Maturity of any
    Security;

         (4) impair the right of any Holder to receive payment of Accreted Value
    of and interest on such Holder's Securities on or after the due dates
    therefor or to institute suit for the enforcement of any payment on or with
    respect to such Holder's Securities or any Subsidiary Guaranty;

         (5) reduce the amount payable upon the redemption or repurchase of any
    Security under Article III or Section 4.07 or 4.14, change the time at which
    any Security may be redeemed in accordance with Article III, or, at any time
    after a Change of Control or Asset Sale has occurred, change the time at
    which any Change of Control Offer or Prepayment Offer must be made or at
    which the Securities must be repurchased pursuant to such Change of Control
    Offer or Prepayment Offer;

         (6) make any Security payable in money other than that stated in the
    Security;

         (7) make any change in Article XI that adversely affects the rights of
    any Securityholder under Article XI;

         (8) make any change in any Subsidiary Guaranty that would adversely
    affect the Securityholders;

         (9) release any security interest that may have been granted in favor
    of the Holders other than pursuant to the terms of such security interest;

         (10) make any change in Section 6.04 or 6.07 or the second sentence of
    this Section 9.02;

         (11) subordinate the Securities or any Subsidiary Guaranty to any other
    obligation of the Company or the applicable Subsidiary Guarantor; or

         (12) modify any provision of this Indenture relating to the calculation
    of Accreted Value.

         It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent approves the substance thereof.

         An amendment under this Section 9.02 may not make any change that
adversely affects the rights under Article X or XI of any holder of Designated
Senior Debt then outstanding unless the holders of such Designated Senior Debt
(or their authorized representative) consent to such change.

         After an amendment under this Section 9.02 becomes effective, the
Company shall mail to Securityholders a notice briefly describing such
amendment. The failure to give such notice to all Securityholders, or any defect
therein, shall not impair or affect the validity of an amendment under this
Section 9.02.

                                       59
<PAGE>

         SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to
this Indenture or the Securities shall comply with the TIA as then in effect.

         SECTION 9.04. Revocation and Effect of Consents and Waivers. A consent
to an amendment or a waiver by a Holder of a Security shall bind the Holder and
every subsequent Holder of that Security or portion of the Security that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent or waiver is not made on the Security. However, any such Holder or
subsequent Holder may revoke the consent or waiver as to such Holder's Security
or portion of the Security if the Trustee receives the notice of revocation
before the date the amendment or waiver becomes effective. After an amendment or
waiver becomes effective, it shall bind every Securityholder. An amendment or
waiver becomes effective upon the execution of such amendment or waiver by the
Trustee.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Securityholders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Securityholders at such
record date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date. No such consent shall be valid or effective for more than 120
days after such record date.

         SECTION 9.05. Notation on or Exchange of Securities. If an amendment
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver such Security to the Trustee. The Trustee may place an
appropriate notation on the Security regarding the changed terms and return such
Security to the Holder. Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Security shall issue and the Trustee
shall authenticate a new Security that reflects the changed terms. Failure to
make the appropriate notation or to issue a new Security shall not affect the
validity of such amendment.

         SECTION 9.06. Trustee To Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article IX if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that such
amendment is authorized or permitted by this Indenture.

         SECTION 9.07. Payment for Consent. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

                                    ARTICLE X

                              Subsidiary Guarantees

         SECTION 10.01. Subsidiary Guarantees. Subject to Article XI, each
Subsidiary Guarantor hereby unconditionally guarantees, jointly and severally,
to each

                                       60
<PAGE>

Holder and to the Trustee and its successors and assigns (a) the full and
punctual payment of the Accreted Value of, and premium, if any, and interest on
the Securities when due, whether at maturity, by acceleration, by redemption or
otherwise, and all other monetary obligations of the Company under this
Indenture and the Securities, and (b) the full and punctual performance within
applicable grace periods of all other obligations of the Company under this
Indenture and the Securities (all the foregoing being hereinafter collectively
called the "Obligations"). Each Subsidiary Guarantor further agrees that the
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from such Subsidiary Guarantor, and that such Subsidiary
Guarantor will remain bound under this Article X notwithstanding any extension
or renewal of any Obligation.

         Each Subsidiary Guarantor waives presentation to, demand of, payment
from and protest to the Company of any of the Obligations and also waives notice
of protest for nonpayment. Subject to Article XI, each Subsidiary Guarantor
waives notice of any default under the Securities or the Obligations. The
obligations of each Subsidiary Guarantor hereunder shall not be affected by (a)
the failure of any Holder or the Trustee to assert any claim or demand or to
enforce any right or remedy against the Company or any other Person under this
Indenture, the Securities or any other agreement or otherwise; (b) any extension
or renewal of any thereof; (c) any rescission, waiver, amendment or modification
of any of the terms or provisions of this Indenture, the Securities or any other
agreement; (d) the release of any security held by any Holder or the Trustee for
the Obligations or any of them; (e) the failure of any Holder or the Trustee to
exercise any right or remedy against any other guarantor of the Obligations; or
(f) any change in the ownership of such Subsidiary Guarantor.

         Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty
herein constitutes a guarantee of payment, performance and compliance when due
(and not a guarantee of collection) and waives any right to require that any
resort be had by any Holder or the Trustee to any security held for payment of
the Obligations.

         Each Subsidiary Guaranty is, to the extent and in the manner set forth
in Article XI, subordinated and subject in right of payment to the prior payment
in full of all Designated Senior Debt of the Subsidiary Guarantor giving such
Subsidiary Guaranty and is made subject to such provisions of this Indenture.

         Except as expressly set forth in Sections 4.06, 5.02 and 8.01(b), the
obligations of each Subsidiary Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Guaranteed Obligations or otherwise. Without limiting the generality of the
foregoing, the obligations of each Subsidiary Guarantor herein shall not be
discharged or impaired or otherwise affected by the failure of any Holder or the
Trustee to assert any claim or demand or to enforce any remedy under this
Indenture, the Securities or any other agreement, by any waiver or modification
of any thereof, by any default, failure or delay in the performance of the
obligations, or by any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of
such Subsidiary Guarantor or would otherwise operate as a discharge of such
Subsidiary Guarantor as a matter of law or equity, except for any gross
negligence, wilful misconduct or bad faith by such Holder or the Trustee.

         Each Subsidiary Guarantor further agrees that its Subsidiary Guaranty
herein shall continue to be effective or be reinstated, as the case may be, if
at any time payment, or any part thereof, of Accreted Value of or premium, if
any, or interest on any

                                       61
<PAGE>

Obligation is rescinded or must otherwise be restored by any Holder or the
Trustee upon the bankruptcy or reorganization of the Company or otherwise.

         In furtherance of the foregoing and not in limitation of any other
right that any Holder or the Trustee has at law or in equity against any
Subsidiary Guarantor by virtue hereof, and subject in all instances to Article
XI hereof, upon the failure of the Company to pay the Accreted Value of or
premium, if any, or interest on any Obligation when and as the same shall become
due, whether at maturity, by acceleration, by redemption or otherwise, or to
perform or comply with any other Obligation, each Subsidiary Guarantor hereby
promises to and will, upon receipt of written demand by the Trustee, forthwith
pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal
to the sum of (i) the unpaid amount of such Obligations, (ii) accrued and unpaid
premium, if any, and interest on such Obligations (but only to the extent not
prohibited by law), and (iii) all other monetary Obligations of the Company to
the Holders and the Trustee.

         Each Subsidiary Guarantor agrees that it shall not be entitled to any
right of subrogation in respect of any Obligations guaranteed hereby until
payment in full in cash of all Obligations and all obligations to which the
Obligations are subordinated as provided in Article XI. Each Subsidiary
Guarantor further agrees that, as between it, on the one hand, and the Holders
and the Trustee, on the other hand, (x) the maturity of the Obligations
guaranteed hereby may be accelerated as provided in Article VI for the purposes
of such Subsidiary Guarantor's Subsidiary Guaranty herein, notwithstanding any
stay, injunction or other prohibition preventing such acceleration in respect of
the Obligations guaranteed hereby, and (y) in the event of any declaration of
acceleration of such Obligations as provided in Article VI, such Obligations
(whether or not due and payable) shall, subject to Article XI hereof, forthwith
become due and payable by such Subsidiary Guarantor for the purposes of this
Section 10.01.

         Each Subsidiary Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or any
Holder in enforcing any rights under this Section 10.01.

         SECTION 10.02. Contribution. Each of the Company and any Subsidiary
Guarantor (a "Contributing Party") agrees (subject to Article XI) that, in the
event a payment shall be made by any other Subsidiary Guarantor under any
Subsidiary Guaranty (the "Claiming Guarantor"), the Contributing Party shall
indemnify the Claiming Guarantor in an amount equal to the amount of such
payment multiplied by a fraction, the numerator of which shall be the net worth
of the Contributing Party on the date hereof and the denominator of which shall
be the aggregate net worth of the Company and all the Subsidiary Guarantors on
the date hereof (or, in the case of any Subsidiary Guarantor becoming a party
hereto pursuant to Section 9.01, the date of the supplemental indenture executed
and delivered by such Subsidiary Guarantor).

         SECTION 10.03. Successors and Assigns. This Article X shall be binding
upon each Subsidiary Guarantor and its successors and assigns and shall inure to
the benefit of the successors and assigns of the Trustee and the Holders and, in
the event of any transfer or assignment of rights by any Holder or the Trustee,
the rights and privileges conferred upon that party in this Indenture and in the
Securities shall automatically extend to and be vested in such transferee or
assignee, all subject to the terms and conditions of this Indenture.

         SECTION 10.04. No Waiver. Neither a failure nor a delay on the part of
either the Trustee or the Holders in exercising any right, power or privilege
under this Article X shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights,

                                       62
<PAGE>

remedies and benefits of the Trustee and the Holders herein expressly specified
are cumulative and not exclusive of any other rights, remedies or benefits that
either may have under this Article X at law, in equity, by statute or otherwise.

         SECTION 10.05. Modification. No modification, amendment or waiver of
any provision of this Article X, nor the consent to any departure by any
Subsidiary Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Trustee, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. No notice to or demand on any Subsidiary Guarantor in any case shall
entitle such Subsidiary Guarantor to any other or further notice or demand in
the same, similar or other circumstances.

         SECTION 10.06. Execution of Supplemental Indenture for Future
Subsidiary Guarantors. Each Subsidiary that is required to become a Subsidiary
Guarantor pursuant to Section 4.15 shall promptly execute and deliver to the
Trustee a supplemental indenture in the form of Appendix B hereto pursuant to
which such Subsidiary shall become a Subsidiary Guarantor under this Article X
and shall guarantee the Obligations subject in all respects to Article XI
hereof. Concurrently with the execution and delivery of such supplemental
indenture, the Company shall deliver to the Trustee an Opinion of Counsel to the
effect that such supplemental indenture has been duly authorized, executed and
delivered by such Subsidiary and that, subject to the application of bankruptcy,
insolvency, moratorium, fraudulent conveyance or transfer and other similar laws
relating to creditors' rights generally and to the principles of equity, whether
considered in a proceeding at law or in equity, the Subsidiary Guaranty of such
Subsidiary Guarantor is a legal, valid and binding obligation of such Subsidiary
Guarantor, enforceable against such Subsidiary Guarantor in accordance with its
terms.

                                       63

                                   ARTICLE XI

                     Subordination of Subsidiary Guarantees

         SECTION 11.01. Agreement To Subordinate. Each Subsidiary Guarantor
agrees, and each Securityholder by accepting a Security agrees, that the
Obligations of such Subsidiary Guarantor are subordinated in right of payment,
to the extent and in the manner provided in this Article XI, to the payment when
due of all Designated Senior Debt of such Subsidiary Guarantor and that the
subordination is for the benefit of and enforceable by the holders of such
Designated Senior Debt. Subject to the foregoing, the Obligations of each
Subsidiary Guarantor shall in all respects rank pari passu with all existing and
future Senior Debt of such Subsidiary Guarantor and senior to all existing and
future subordinated Debt of such Subsidiary Guarantor, and only Designated
Senior Debt shall rank senior to the Obligations of such Subsidiary Guarantor in
accordance with the provisions set forth herein.

         SECTION 11.02. Liquidation, Dissolution, Bankruptcy. Upon any payment
or distribution of the assets of any Subsidiary Guarantor to creditors upon a
total or partial liquidation or a total or partial dissolution of such
Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to such Subsidiary Guarantor or its
property:

         (1) holders of Designated Senior Debt of such Subsidiary Guarantor
    shall be entitled to receive payment in full in cash of such Designated
    Senior Debt before Securityholders shall be entitled to receive any payment
    pursuant to any Obligations of such Subsidiary Guarantor; and

         (2) until the Designated Senior Debt of any Subsidiary Guarantor is
    paid in full in cash, any distribution made by or on behalf of such
    Subsidiary Guarantor to which Securityholders would be entitled but for this
    Article XI shall be made to holders of the Designated Senior Debt as their
    interests may appear, except that all Securityholders may receive and retain
    shares of stock and any debt securities of such Subsidiary Guarantor that
    are subordinated to Designated Senior Debt of such Subsidiary Guarantor to
    at least the same extent as the Obligations of such Subsidiary Guarantor are
    subordinated to Designated Senior Debt of such Subsidiary Guarantor.

         SECTION 11.03. Default on Designated Senior Debt of Subsidiary
Guarantor. No Subsidiary Guarantor may make any payment pursuant to any of its
Obligations or repurchase, redeem or otherwise retire or defease any Securities
or other Obligations (collectively, "pay its Subsidiary Guaranty") if (i) any
principal, premium or interest in respect of the Designated Senior Debt of such
Subsidiary Guarantor is not paid when due (including at maturity), or (ii) any
other default on Designated Senior Debt of such Subsidiary Guarantor occurs and
the maturity of such Designated Senior Debt is accelerated in accordance with
its terms unless, in either case, (x) the default has been cured or waived and
any such acceleration has been rescinded, or (y) such Designated Senior Debt has
been paid in full in cash; provided, however, that any Subsidiary Guarantor may
pay its Subsidiary Guaranty without regard to the foregoing if such Subsidiary
Guarantor and the Trustee receive written notice approving such payment from the
holders of such Designated Senior Debt (or the authorized representative
therefor) of such Subsidiary Guarantor. In addition, during the continuance of
any default (other than a default described in clause (i) or (ii) of the
preceding sentence) with respect to any Designated Senior Debt pursuant to which
the maturity thereof may be accelerated immediately without further notice
(except any notice required to effect the acceleration) or the expiration of any
applicable grace period, no Subsidiary Guarantor may pay its

                                       64
<PAGE>

Subsidiary Guaranty for a period (a "Payment Blockage Period") commencing upon
the receipt by such Subsidiary Guarantor and the Trustee of written notice of
such default from a representative under such Designated Senior Debt specifying
an election to effect a Payment Blockage Period (a "Payment Blockage Notice")
and ending 179 days thereafter (unless such Payment Blockage Period is earlier
terminated (a) by written notice to the Trustee and such Subsidiary Guarantor
from such authorized representative or the holders of such Designated Senior
Debt, (b) because such default is no longer continuing, or (c) because all such
Designated Senior Debt has been repaid in full in cash). Unless the holders of
such Designated Senior Debt shall have accelerated the maturity of such
Designated Senior Debt and not rescinded such acceleration, any Subsidiary
Guarantor may (unless otherwise prohibited as described in Section 11.02 or the
first or second sentences of this paragraph) resume payments pursuant to its
Subsidiary Guaranty after such Payment Blockage Period. Not more than one
Payment Blockage Notice may be given in any consecutive 360-day period,
irrespective of the number of defaults during such period.

         SECTION 11.04. Demand for Payment. If a demand for payment is made on a
Subsidiary Guarantor pursuant to Article X, such Subsidiary Guarantor may not
pay its Subsidiary Guaranty, and neither the Trustee nor any Securityholder may
retain any such payment, until ten Business Days after the holders of Designated
Senior Debt (or their authorized representative) receive notice of such demand
and, thereafter, may pay its Subsidiary Guaranty only if this Indenture
otherwise permits payment at that time.

         SECTION 11.05. When Distribution Must Be Paid Over. If a distribution
is made to the Trustee or any Securityholders that because of this Article XI
should not have been made to them, the Trustee or such Securityholders who
receive the distribution shall hold it in trust for holders of the Designated
Senior Debt and promptly pay it over to them or their authorized representative
as their interests may appear.

         SECTION 11.06. Subrogation. After all Designated Senior Debt of a
Subsidiary Guarantor is paid in full in cash and until the Securities are paid
in full in cash, Securityholders shall be subrogated to the rights of holders of
Designated Senior Debt to receive distributions applicable to Designated Senior
Debt. A distribution made under this Article XI to holders of such Designated
Senior Debt that otherwise would have been made to Securityholders is not, as
between the relevant Subsidiary Guarantor and Securityholders, a payment by such
Subsidiary Guarantor on such Designated Senior Debt.

         SECTION 11.07. Relative Rights. This Article XI defines the relative
rights of Securityholders and holders of Designated Senior Debt of a Subsidiary
Guarantor. Nothing in this Indenture shall:

         (1) impair, as between a Subsidiary Guarantor and Securityholders, the
    obligation of such Subsidiary Guarantor, which is absolute and
    unconditional, to pay the Obligations to the extent set forth in Article X
    or the relevant Subsidiary Guaranty; or

         (2) prevent the Trustee or any Securityholder from exercising its
    available remedies upon a default by such Subsidiary Guarantor under the
    Obligations, subject to the rights of holders of Designated Senior Debt of
    such Subsidiary Guarantor to receive distributions otherwise payable to
    Securityholders.

         SECTION 11.08. Subordination May Not Be Impaired by Subsidiary
Guarantor. No right of any holder of Designated Senior Debt of any Subsidiary
Guarantor to enforce the subordination of the Obligation of such Subsidiary
Guarantor

                                       65
<PAGE>

shall be impaired by any act or failure to act by such Subsidiary Guarantor or
the Company or by any of their failure to comply with this Indenture.

         SECTION 11.09. Rights of Trustee and Paying Agent. Notwithstanding
Section 11.03, the Trustee or Paying Agent may continue to make payments on any
Subsidiary Guaranty and shall not, absent gross negligence or bad faith, be
charged with knowledge of the existence of facts that would prohibit the making
of any such payments unless, not less than two Business Days prior to the date
of such payment, a Trust Officer receives written notice satisfactory to it that
payments may not be made under this Article XI. The Company, the relevant
Subsidiary Guarantor, the Registrar or co-registrar, the Paying Agent, an
authorized representative or a holder of Designated Senior Debt of any
Subsidiary Guarantor may give the notice; provided, however, that, if any
Designated Senior Debt of any Subsidiary Guarantor has an authorized
representative, only such authorized representative may give the notice.

         The Trustee in its individual or any other capacity may hold Designated
Senior Debt with the same rights it would have if it were not Trustee. The
Registrar and co-registrar and the Paying Agent may do the same with like
rights. The Trustee shall be entitled to all the rights set forth in this
Article XI with respect to any Designated Senior Debt of any Subsidiary
Guarantor that may at any time be held by it, to the same extent as any other
holder of Designated Senior Debt; and nothing in Article VII shall deprive the
Trustee of any of its rights as such holder. Nothing in this Article XI shall
apply to claims of, or payments to, the Trustee under or pursuant to Section
7.07.

         SECTION 11.10. Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Designated Senior
Debt of any Subsidiary Guarantor, the distribution may be made and the notice
given to the authorized representative, if any, of such Designated Senior Debt.

         SECTION 11.11. Article XI Not To Prevent Events of Default Under a
Subsidiary Guaranty or Limit Right To Demand Payment. The failure to make a
payment pursuant to a Subsidiary Guaranty by reason of any provision in this
Article XI shall not be construed as preventing the occurrence of a default
under such Subsidiary Guaranty. Nothing in this Article XI shall have any effect
on the right of the Securityholders or the Trustee to make a demand for payment
on any Subsidiary Guarantor pursuant to Article X or the relevant Subsidiary
Guaranty.

         SECTION 11.12. Trustee Entitled To Rely. Upon any payment or
distribution pursuant to this Article XI, the Trustee and the Securityholders
shall be entitled to rely, except to the extent such reliance would constitute
gross negligence or bad faith, (i) upon any order or decree of a court of
competent jurisdiction in which any proceedings of the nature referred to in
Section 11.02 are pending, (ii) upon a certificate of the liquidating trustee or
agent or other Person making such payment or distribution to the Trustee or to
the Securityholders, or (iii) upon the authorized representative, if any, for
the holders of Designated Senior Debt of any Subsidiary Guarantor for the
purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Designated Senior Debt and other Debt of such
Subsidiary Guarantor, the amount thereof or payable thereon, the amount or
amounts paid or distributed thereon and all other facts pertinent thereto or to
this Article XI. In the event that the Trustee determines, in good faith, that
evidence is required with respect to the right of any Person as a holder of
Designated Senior Debt of any Subsidiary Guarantor to participate in any payment
or distribution pursuant to this Article XI, the Trustee may request such Person
to furnish evidence to the reasonable satisfaction of the Trustee as to the
amount of Designated Senior Debt of such Subsidiary Guarantor held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and other facts pertinent to the rights of such Person
under this Article XI, and, if such evidence is not

                                       66
<PAGE>

furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment. The
provisions of Sections 7.01 and 7.02 shall be applicable to all actions or
omissions of actions by the Trustee pursuant to this Article XI. Notwithstanding
anything to the contrary contained in this Section 11.12, the provisions of this
Section 11.12 shall not change, modify or otherwise affect the rights of the
holders of Designated Senior Debt.

         SECTION 11.13. Trustee To Effectuate Subordination. Each Securityholder
by accepting a Security authorizes and directs the Trustee on his behalf to take
such action as may be necessary or appropriate to acknowledge or effectuate the
subordination between the Securityholders and the holders of Designated Senior
Debt of any Subsidiary Guarantor as provided in this Article XI and appoints the
Trustee as attorney-in-fact for any and all such purposes.

         SECTION 11.14. Trustee Not Fiduciary for Holders of Designated Senior
Debt of Subsidiary Guarantor. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Designated Senior Debt of any Subsidiary
Guarantor and, absent gross negligence or bad faith, shall not be liable to any
such holders if it shall mistakenly pay over or distribute to Securityholders or
the Company or any other Person money or assets to which any holders of such
Designated Senior Debt shall be entitled by virtue of this Article XI or
otherwise.

         SECTION 11.15. Reliance by Holders of Designated Senior Debt on
Subordination Provisions. Each Securityholder by accepting a Security
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any
Designated Senior Debt of any Subsidiary Guarantor, whether such Designated
Senior Debt was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, or to continue to hold, such
Designated Senior Debt and such holder of Designated Senior Debt shall be deemed
conclusively to have relied on such subordination provisions in acquiring and

         SECTION 12.06. When Securities Disregarded. In determining whether the

concurred in any direction, waiver or consent, Securities owned by the Company,
any Subsidiary Guarantor or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
Subsidiary Guarantor shall be disregarded and deemed not to be outstanding,
except that, for the purpose of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Securities
that the Trustee knows are so owned shall be so disregarded. Also, subject to
the foregoing, only Securities outstanding at the time shall be considered in
any such determination.

         SECTION 12.07. Rules by Trustee, Paying Agent and Registrar. The

accrue for the intervening period. If a regular record date is a Legal Holiday,
the record date shall not be affected.

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

"Agent Members"......................................................2.1(b)
"Global Security"....................................................2.1(a)

         2. The Securities

         2.1 Form and Dating

              The Securities will be issued and exchanged by the Company
pursuant to the Exchange Offers.

              (a) Global Securities. Securities shall be issued in the form of
one or more permanent global Securities in definitive, fully registered form
(the "Global Securities") without interest coupons and with the global
securities legend set forth in Exhibit 1 hereto, which shall be deposited on
behalf of the initial holders of the Securities represented thereby with the
Securities Custodian, and registered in the name of the Depository or a nominee
of the Depository, duly executed by the Company and authenticated by the Trustee
as provided in this Indenture. The aggregate principal amount at maturity of the
Global Securities may from time to time be increased or decreased by adjustments
made on the records of the Trustee and the Depository or its nominee as
hereinafter provided.

              (b) Book-Entry Provisions. This Section 2.1(b) shall apply only to
a Global Security deposited with or on behalf of the Depository.

              The Company shall execute and the Trustee shall, in accordance

and deliver initially one or more Global Securities that (a) shall be registered

<PAGE>

for such Global Security or Global Securities or the nominee of such Depository,
and (b) shall be delivered by the Trustee to such Depository or pursuant to such
Depository's instructions or held by the Trustee as Securities Custodian.

              Members of, or participants in, the Depository ("Agent Members")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depository or by the Trustee as Securities Custodian
or under such Global Security, and the Depository may be treated by the Company,
the Trustee and any agent of the Company or the Trustee as the absolute owner of
such Global Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee or any agent of the
Company or the Trustee from giving effect to any written certification, proxy or
other authorization furnished by the Depository or impair, as between the
Depository and its Agent Members, the operation of customary practices of such
Depository governing the exercise of the rights of a holder of a beneficial
interest in any Global Security.

              (c) Definitive Securities. Except as provided in Section 2.3 or
2.4, owners of beneficial interests in Global Securities will not be entitled to
receive physical delivery of Definitive Securities.

         2.2 Authentication. The Trustee shall authenticate and make available
for delivery, upon a written order of the Company signed by two Officers
Securities for original issue on the date thereof in an aggregate principal
amount at maturity of up to $237,689,000. Such order shall specify the amount of
the Securities to be authenticated and the date on which the Securities are to
be authenticated. The aggregate principal amount at maturity of Securities
outstanding at any time may not exceed $237,689,000, except as provided in
Section 2.07 of the Indenture.

         2.3 Transfer and Exchange. (a) Transfer and Exchange of Definitive
Securities. When Definitive Securities are presented to the Registrar or any
co-registrar with a request:

              (x) to register the transfer of such Definitive Securities; or

              (y) to exchange such Definitive Securities for an equal Accreted
         Value of Definitive Securities of other authorized denominations,

the Registrar or co-registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met;
provided, however, that the Definitive Securities surrendered for transfer or
exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form reasonably satisfactory to the Company and the Registrar or any
co-registrar, duly executed by the Holder thereof or his attorney duly
authorized in writing.

              (b) Transfer and Exchange of Global Securities.

              (i) The transfer and exchange of Global Securities or beneficial
         interests therein shall be effected through the Depository, in
         accordance with this Indenture (including applicable restrictions on
         transfer set forth herein, if any) and the procedures of the Depository
         therefor. A transferor of a beneficial interest in a Global Security
         shall deliver a written order given in accordance with the Depository's
         procedures containing information regarding the participant account of
         the Depository to be credited with a beneficial interest in such Global
         Security or another Global Security and such account shall be credited
         in accordance with such order with a beneficial interest in the
         applicable Global Security and the

                                        2
<PAGE>

         account of the Person making the transfer shall be debited by an
         amount equal to the beneficial interest in the Global Security being
         transferred.

              (ii) If the proposed transfer is a transfer of a beneficial
         interest in one Global Security to a beneficial interest in another
         Global Security, the Registrar or co-registrar shall reflect on its
         books and records the date and an increase in the principal amount at
         maturity of the Global Security to which such interest is being
         transferred in an amount equal to the principal amount at maturity of
         the interest to be so transferred, and the Registrar or co-registrar
         shall reflect on its books and records the date and a corresponding
         decrease in the principal amount at maturity of the Global Security
         from which such interest is being transferred.

              (iii) Notwithstanding any other provisions of this Appendix A
         (other than the provisions set forth in Section 2.4), a Global Security
         may not be transferred as a whole except by the Depository to a nominee
         of the Depository or by a nominee of the Depository to the Depository
         or another nominee of the Depository or by the Depository or any such
         nominee to a successor Depository or a nominee of such successor
         Depository.

              (c) Cancellation or Adjustment of Global Security. At such time as
all beneficial interests in a Global Security have either been exchanged for
Definitive Securities, transferred, redeemed, repurchased or canceled, such
Global Security shall be returned by the Depository to the Trustee for
cancellation or retained and canceled by the Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Security is exchanged for
Definitive Securities, transferred in exchange for an interest in another Global
Security, redeemed, repurchased or canceled, the principal amount at maturity of
Securities represented by such Global Security shall be reduced and an
adjustment shall be made on the books and records of the Trustee (if it is then
the Securities Custodian for such Global Security) with respect to such Global
Security, by the Trustee or the Securities Custodian, to reflect such reduction.

              (d) Obligations with Respect to Transfers and Exchanges of
         Securities.

              (i) To permit registrations of transfers and exchanges, the
         Company shall execute and the Trustee shall authenticate Definitive
         Securities and Global Securities at the Registrar's or any
         co-registrar's request.

              (ii) No service charge shall be made for any registration of
         transfer or exchange, but the Company may require payment of a sum
         sufficient to cover any transfer tax, assessments, or similar
         governmental charge payable in connection therewith (other than any
         such transfer taxes, assessments or similar governmental charge payable
         upon exchange or transfer pursuant to Sections 3.06, 4.07, 4.14 and
         9.05 of the Indenture).

              (iii) Prior to the due presentation for registration of transfer
         of any Security, the Company, the Trustee, the Paying Agent or the
         Registrar or any co-registrar may deem and treat the person in whose
         name a Security is registered as the absolute owner of such Security
         for the purpose of receiving payment of Accreted Value of and interest
         on such Security and for all other purposes whatsoever, whether or not
         such Security is overdue, and none of the Company, the Trustee, the
         Paying Agent or the Registrar or any co-registrar shall be affected by
         notice to the contrary.

              (iv) The Company shall not be required to make and the Registrar
         or co- registrar need not register transfers or exchanges of Securities
         selected for redemption (except, in the case of Securities to be
         redeemed in part, the portion

                                        3
<PAGE>

         thereof not to be redeemed) or any Securities for a period of 15
         days before a selection of Securities to be redeemed.

              (v) All Securities issued upon any transfer or exchange pursuant
         to the terms of this Indenture shall evidence the same debt and shall
         be entitled to the same benefits under this Indenture as the Securities
         surrendered upon such transfer or exchange.

              (e) No Obligation of the Trustee.

              (i) The Trustee shall have no responsibility or obligation to any
         beneficial owner of a Global Security, a member of, or a participant in
         the Depository or any other Person with respect to the accuracy of the
         records of the Depository or its nominee or of any participant or
         member thereof, with respect to any ownership interest in the
         Securities or with respect to the delivery to any participant, member,
         beneficial owner or other Person (other than the Depository) of any
         notice (including any notice of redemption or repurchase) or the
         payment of any amount, under or with respect to such Securities. All
         notices and communications to be given to the Holders and all payments
         to be made to Holders under the Securities shall be given or made only
         to the registered Holders (which shall be the Depository or its nominee
         in the case of a Global Security). The rights of beneficial owners in
         any Global Security shall be exercised only through the Depository
         subject to the applicable rules and procedures of the Depository. The
         Trustee may rely and shall be fully protected in relying upon
         information furnished by the Depository with respect to its members,
         participants and any beneficial owners.

              (ii) The Trustee shall have no obligation or duty to monitor,
         determine or inquire as to compliance with any restrictions on transfer
         imposed under this Indenture or under applicable law with respect to
         any transfer of any interest in any Security (including any transfers
         between or among Depository participants, members or beneficial owners
         in any Global Security) other than to require delivery of such
         certificates and other documentation or evidence as are expressly
         required by, and to do so if and when expressly required by, the terms
         of this Indenture, and to examine the same to determine substantial
         compliance as to form with the express requirements hereof.

         2.4 Definitive Securities

              (a) A Global Security deposited with the Depository or with the
Trustee as Securities Custodian pursuant to Section 2.1 shall be transferred to
the beneficial owners thereof in the form of Definitive Securities in an
aggregate principal amount at maturity equal to the principal amount at maturity
of such Global Security, in exchange for such Global Security, only if such
transfer complies with Section 2.3 and (i) the Depository notifies the Company
that it is unwilling or unable to continue as a Depository for such Global
Security or if at any time the Depository ceases to be a "clearing agency"
registered under the Exchange Act, and a successor depository is not appointed
by the Company within 90 days of such notice, or (ii) an Event of Default has
occurred and is continuing, or (iii) the Company, in its sole discretion,
notifies the Trustee in writing that it elects to cause the issuance of
certificated Securities under this Indenture.

              (b) Any Global Security that is transferable to the beneficial
owners thereof pursuant to this Section 2.4 shall be surrendered by the

                           [FORM OF BACK OF SECURITY]

                        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
twelve 30-day months. The Company shall pay interest on overdue Accreted Value
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 Accreted Value payments. The Company will pay Accreted Value 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 Accreted Value, 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 Accreted Value,
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
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 immediately 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.

<PAGE>

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 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:

                                                            Redemption
Period                                                      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

                                        2

<PAGE>

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
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.

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

                                        3

<PAGE>

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 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.

                                       4

<PAGE>

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.

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.
