          "Affiliate" of any specified Person means any other Person directly or

     during such period; and

          (2)  any Subsidiary of the Company that is not a Restricted Subsidiary
     on the Transaction Date shall be deemed not to have been a Restricted
     Subsidiary at any time during such period.

In addition to and without limitation of the foregoing, for purposes of this
definition only, "Consolidated Cash Flow" shall be calculated after giving

Asset Acquisition giving rise to the need to make such calculation as a result
of the Company or one of the Restricted Subsidiaries (including any Person who
becomes a Restricted Subsidiary as a result of the Asset Acquisition) Incurring,
assuming or otherwise being liable for Acquired Indebtedness) occurring during
the period commencing on the first day of such two-fiscal-quarter period to and

     pursuant to which such Person shall become a Restricted Subsidiary or shall
     be merged with or into the Company or any Restricted Subsidiary; or

          (2)  any acquisition by the Company or any Restricted Subsidiary of
     the property or assets of any Person which constitute all or substantially
     all of an operating unit or line of business of such Person.

          "Asset Disposition" means any sale, transfer or other disposition
(including, without limitation, by merger, consolidation or Sale/Leaseback

          (2)  any License for the provision of wireless telecommunications
     services held by the Company or any Restricted Subsidiary (whether by sale
     of Capital Stock or otherwise); or

          (3)  any other property or assets of the Company or any Subsidiary of

provided, however, that an Asset Disposition shall not include:
--------  -------

          (A)  any sale, transfer or other disposition of shares of Capital
     Stock, property or assets by a Restricted Subsidiary to the Company or to

Security for registration of transfer and in compliance with the Appendix. When
a Security is presented to the Registrar with a request to register a transfer,
the Registrar shall register the transfer as requested if the requirements of
Section 8-401(a)(l) of the Uniform Commercial Code are met. When Securities are
presented to the Registrar with a request to exchange them for an equal
principal amount of Securities of other denominations, the Registrar shall make
the exchange as requested if the same requirements are met. To permit
registration of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate Securities (in the form of Exhibit A or Exhibit B, as
appropriate) at the Registrar's request. The Company may require payment of a
sum sufficient to pay all taxes, assessments or other governmental charges in
connection with any transfer or exchange pursuant to this Section 2.06. The
Company shall not be required to make and the 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 thereof not to be
redeemed) or any Securities for a period of 15 days before a selection of
Securities to be redeemed.

          Prior to the due presentation for registration of transfer of any
Security, the Company, any Subsidiary Guarantor, the Trustee, the Paying Agent
and the Registrar will 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, if any, on such Security and for all other purposes
whatsoever, whether or not such Security is overdue, and none of the Company,
any Subsidiary Guarantor, the Trustee, the Paying Agent, or the Registrar shall
be affected by notice to the contrary.

          Any Holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interest in such Global Security
may be effected only through a book-entry system maintained by (i) the Holder of
such Global Security (or its agent) or (ii) any Holder of a beneficial interest
in such Global Security, and that ownership of a beneficial interest in such
Global Security shall be required to be reflected in a book entry.

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

          SECTION 2.07.  Replacement Securities.  If a mutilated Security is
                         ----------------------
surrendered to the Registrar or if the Holder of a Security claims that the
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, such that the Holder (i)
satisfies the Company and the Trustee within a reasonable time after such Holder
has notice of such loss, destruction or wrongful taking and the Registrar does
not register a transfer prior to receiving such notification, (ii) makes such
request to the Company or the Trustee prior to the Security being acquired by a
protected purchaser as defined in Section 8-303 of the Uniform Commercial Code
(a "protected purchaser") and (iii) satisfies any other reasonable requirements
of the Trustee. If required by the Company or the Trustee, 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 and the 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. In the event any such mutilated, lost, destroyed or wrongfully taken
Security has become or is about to become due and payable, the Company in its
discretion may pay such Security instead of issuing a new Security in
replacement thereof.

                                                                              27

          Every replacement Security is an additional obligation of the Company.

          The provisions of this Section 2.07 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, lost, destroyed or wrongfully taken
Securities.

          SECTION 2.08.  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 cancelation and those described in this Section
2.08 as not outstanding. Subject to Section 14.06, 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 2.07, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a protected 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 and interest and liquidated damages payable on that date with
respect to the Securities (or portions thereof) to be redeemed or maturing, as
the case may be, and the Paying Agent is not prohibited from paying such money
to the Securityholders on that date pursuant to the terms of this Indenture,
then on and after that date such Securities (or portions thereof) cease to be
outstanding and interest on them ceases to accrue.

          SECTION 2.09.  Temporary Securities.  In the event that Definitive
                         --------------------
Securities (as defined in the Appendix) are to be issued under the terms of this
Indenture, until such 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 upon surrender of such temporary Securities at the office or agency
of the Company, without charge to the Holder.

          SECTION 2.10.  Cancelation.  The Company at any time may deliver
                         -----------
Securities to the Trustee for cancelation. 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 all
Securities surrendered for registration of transfer, exchange, payment or
cancelation and deliver canceled Securities to the Company pursuant to written
direction by an Officer. The Company may not issue new Securities to replace
Securities it has redeemed, paid or delivered to the Trustee for cancelation.
The Trustee shall not authenticate Securities in place of canceled Securities
other than pursuant to the terms of this Indenture.

          SECTION 2.11.  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 or cause to be
mailed to each Securityholder a notice that states the special record date, the
payment date and the amount of defaulted interest to be paid.

          SECTION 2.12.  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 solely as a convenience to Holders;
provided, however, that any such notice may state that (i) none of the Company,
--------  -------
any Subsidiary Guarantor, the Trustee or the Paying Agent shall be responsible
for selection or use of such CUSIP numbers, (ii) no representation is made as to
the correctness of such CUSIP numbers either as printed on the Securities or as
contained in any notice of a redemption and (iii) 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.

          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 and the principal amount of Securities
to be redeemed.

          The Company shall give each notice to the Trustee provided for in this
Section 3.01 at least 60 days before the redemption date unless the Trustee
consents to a shorter period. Such notice shall be accompanied by an Officers'
Certificate (which Officers' Certificate shall comply with the requirements of
Section 14.04(1) and 14.05) and an Opinion of Counsel (which Opinion of Counsel
shall comply with the requirements of Section 14.04(2) and 14.05) from the
Company to the effect that such redemption will comply with the conditions
herein. If fewer than all the Securities are to be redeemed, the record date
relating to such redemption shall be selected by the Company and given to the
Trustee, which record date shall be not fewer than 15 days after the date of
notice to the Trustee. Any such notice may be canceled at any time prior to
notice of such redemption being mailed to any Holder and shall thereby be void
and of no effect.

          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 by a method that complies with applicable
               --- ----
legal and securities exchange requirements, if any, and that the Trustee in its
sole discretion shall deem to be 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 principal amount of Securities that have denominations larger
than $1,000. Securities and portions thereof the Trustee selects shall be in
amounts of $1,000 of principal amount or a whole multiple of $1,000 thereof.
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 date for redemption of Securities, the Company shall mail
a notice of redemption by first-class mail to each Holder of Securities to be
redeemed at such Holder's registered address.

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

          (1)  the redemption date;
<PAGE>

                                                                              29

          (2)  the redemption price and the amount of accrued interest to the
     redemption date;

          (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 certificate numbers of certificated securities and principal amounts
     of the particular Securities to be redeemed;

          (6)  that, unless the Company defaults in making such redemption
     payment or the Paying Agent is prohibited from making such payment pursuant
     to the terms of this Indenture, interest on Securities (or portion thereof)
     called for redemption ceases to accrue on and after the redemption date;

          (7)  the CUSIP number, if any, printed on the Securities being
     redeemed; and

          (8)  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 written 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.

          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 and liquidated damages, if
any, to the redemption date; provided, however, that if the redemption date is
                             --------  -------
after a regular record date and on or prior to the interest payment date, the
accrued interest shall be payable to the Securityholder of the redeemed
Securities registered on the relevant record 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 10:00 a.m. on
                         ---------------------------
the redemption date, the Company shall deposit with the Paying Agent (or, if the
Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust)
money sufficient to pay the redemption price of and accrued interest and
liquidated damages (if any) 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 cancelation.  On and after the
redemption date, interest will cease to accrue on Securities or portions thereof
called for redemption so long as the Company has deposited with the Paying Agent
funds sufficient to pay the principal of, plus accrued and unpaid interest and
liquidated damages (if any) on, the Securities to be redeemed.

          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.

                         ---------------------
the principal of and interest on the Securities on the dates and in the manner
provided in the Securities and in this Indenture.  Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due and the Trustee or the Paying Agent, as the case
may be, is not prohibited from paying such money to the Securityholders on that
date pursuant to the terms of this Indenture.

          The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

          SECTION 4.02.  Provision of Financial Information.  (a) Whether or not
                         ----------------------------------

Securities are outstanding, the Company shall furnish to the holders of

     certified independent accountants; and

          (2)  all current reports that would be required to be filed with the

the Exchange and Registration Rights Agreement, whether or not required by the
rules and regulations of the Commission, the Company shall file a copy of all
such information and reports specified in Sections 4.02(a)(1) and 4.02(a)(2)

     disposition of shares of Capital Stock or other ownership interests

     exception provided by this clause (4) shall no longer be applicable to such

     Incurred in connection with, or in contemplation of, the transaction or
     series of related transactions pursuant to which such Restricted Subsidiary
     was acquired by the Company); provided, however, that on the date such
                                   --------  -------
     Restricted Subsidiary is acquired by the Company, the Company would have
     been able to Incur $1.00 of additional Indebtedness pursuant to clause (1)
     above after giving effect to the Incurrence of such Indebtedness pursuant
     to this clause (13) and the acquisition of such Restricted Subsidiary; and

assumed by the acquiring person) shall be deemed Incurred at the time the Person
becomes a Restricted Subsidiary or at the time of the asset acquisition, as the
case may be.

          (c)  For purposes of determining compliance with this Section 4.03:

          (1)  in the event that an item of Indebtedness meets the criteria of
     more than one of the categories of Indebtedness permitted pursuant to
     clauses (1) through (14) above, the Company shall, in its sole discretion,
     be permitted to classify such item of Indebtedness in any manner that
     complies with this Section 4.03 and may from time to time reclassify such
     items of Indebtedness in any manner that would comply with this Section
     4.03 at the time of such reclassification;

          (2)  Indebtedness permitted by this Section 4.03 need not be permitted
     solely by reference to one provision permitting such Indebtedness but may
     be permitted in part by one such provision and in part by one or more other
     provisions of this Section 4.03 permitting such Indebtedness;

          (3)  in the event that Indebtedness meets the criteria of more than
     one of the types of Indebtedness described in this Section 4.03, the
     Company, in its sole discretion,
<PAGE>

                                                                              33

     shall classify such Indebtedness and only be required to include the amount
     of such Indebtedness in one of such clauses; and

          (4) accrual of interest (including interest paid-in-kind) and the

laws and regulations and shall not be deemed to have breached its obligations
under this Section 4.08 by virtue thereof.

          (e)  In the event that, at the time of a Change of Control, the terms
of the Bank Indebtedness restrict or prohibit the repurchase of Securities
pursuant to this Section 4.08, then, prior to the mailing of the notice to
holders of Securities as provided in the immediately following paragraph, but in
any event within 30 days following any Change of Control, the Company shall be
required to:

          (1) repay in full all Bank Indebtedness; or

(1) each Domestic Restricted Subsidiary that Incurs Indebtedness and (2) each
Foreign Restricted Subsidiary that Incurs Material Indebtedness to become a
Subsidiary Guarantor, and, if applicable, execute and deliver to the Trustee a
supplemental indenture in the form set forth in Exhibit C pursuant to which such
Restricted Subsidiary will guarantee payment of the Securities; provided that
                                                                --------
the Company shall not cause any Special Purpose Subsidiary to become a
Subsidiary Guarantor unless such Special Purpose Subsidiary Incurs Indebtedness

Indebtedness Incurred to Refinance such Indebtedness) or FCC Debt; provided
                                                                   --------

-------
other than the Subsidiary Guarantee, any Indebtedness (in the case of a Domestic
Restricted Subsidiary) or Material Indebtedness (in the case of a Foreign
Restricted Subsidiary), the Subsidiary Guarantee of that Subsidiary Guarantor
shall terminate.  Each Subsidiary Guarantee will be limited to an amount not to
exceed the maximum amount that can be guaranteed by that Restricted Subsidiary
without rendering the Subsidiary Guarantee, as it relates to such Restricted
Subsidiary, voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally.

Indenture (a "Designation") only if:

          (1) no Default or Event of Default shall have occurred and be
     continuing at the time of or after giving effect to such Designation;

          (2) the Company would be permitted under this Indenture to make an
     Investment at the time of Designation (assuming the effectiveness of such
     Designation) in an amount (the "Designation Amount") equal to the Fair
     Market Value of the aggregate amount of its Investments in such Subsidiary
     on such date; and

          (3) except in the case of a Subsidiary of the Company in which an
     Investment is being made pursuant to, and as permitted by, paragraph (c) of
     Section 4.04, the Company would be permitted to Incur $1.00 of additional
     Indebtedness pursuant to clause (a)(1) of Section 4.03 at the time of
     Designation (assuming the effectiveness of such Designation).

          (b)  In the event of any such Designation, the Company shall be deemed
to have made an Investment constituting a Restricted Payment pursuant to Section
4.04 for all purposes of this Indenture in the Designation Amount.

          (c)  The Company may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation"), whereupon such Subsidiary shall then
constitute a Restricted Subsidiary, if no Default shall have occurred and be
continuing at the time of and after giving effect to such Revocation.  In the
event of any such Revocation, the Company shall be deemed to continue to have a
permanent Investment in an Unrestricted Subsidiary constituting a

in an amount (if positive) equal to:

          (1) the Fair Market Value of the aggregate amount of the Company's
     Investments in such Subsidiary at the time of such Revocation; less

          (2) the portion (proportionate to the Company's equity interest in
     such Subsidiary) of the Fair Market Value of the net assets of such
     Subsidiary at the time of such Revocation.

          (d)  All Designations and Revocations must be evidenced by a
resolution of the board of directors of the Company delivered to the Trustee
certifying compliance with the foregoing provisions.

not:

          (1) directly or indirectly Incur any Indebtedness that by its terms
     would expressly rank senior in right of payment to the Securities and rank
     subordinate in right of payment to any other Indebtedness of the Company;
     or

          (2) cause or permit any Subsidiary Guarantor to, and no Subsidiary
     Guarantor shall, directly or indirectly, Incur any Indebtedness that by its
     terms would expressly rank senior in right of payment to the Subsidiary
     Guarantee of such Subsidiary Guarantor and rank subordinate in right of
     payment to any other Indebtedness of such Subsidiary Guarantor;

provided that no Indebtedness shall be deemed to be subordinated solely by

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.

          A Default under clause (4), (5), (6), (10), (11) or (12) shall not
constitute an Event of Default until the Trustee or the holders of at least 25%
in aggregate principal amount of the outstanding Securities notify the Company
of the Default and the Company does not cure such Default within the time
specified in clauses (4), (5), (6), (10), (11) or (12) 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".

                                                                              47

          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 which 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 clause (7) of Section 6.01 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 outstanding
Securities by notice to the Company, may declare the principal of and accrued
but unpaid interest on all the Securities to be due and payable.  Upon such a
declaration, such principal and interest shall be due and payable immediately.
If an Event of Default specified in clause (7) of Section 6.01 with respect to
the Company occurs, the principal of and interest on all the Securities shall
ipso facto become and be immediately due and payable without any declaration or
---- -----
other act on the part of the Trustee or any Securityholders.  The Holders of a
majority in aggregate principal amount of the outstanding Securities by notice
to the Trustee may rescind an 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 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
                         ------------------------
principal amount of the Securities by notice to the Trustee may waive an
existing Default and its consequences except (i) a Default in the payment of the
principal amount of, or interest on a Security or (ii) a Default arising from
the failure to redeem or purchase any Security when required pursuant to the
terms of this Indenture or (iii) 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
                         --------------------
principal amount of the Securities 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.  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 indemnification
satisfactory to it in its sole discretion against all losses and expenses caused
by taking or not taking such action.

                                                                              48

          SECTION 6.06.  Limitation on Suits.  Except to enforce the right to
                         --------------------
receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the
Securities unless:

          (1) the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

          (2) the Holders of at least 25% in principal amount of the Securities
     make a written request to the Trustee to pursue the remedy;

          (3) such Holder or Holders offer to the Trustee security or indemnity
     reasonably satisfactory to the Trustee against any loss, liability or
     expense;

          (4) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of security or indemnity; and

          (5) the Holders of a majority in principal amount of the Securities do
     not give the Trustee a direction inconsistent with the request during such
     60-day period.

          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 liquidated damages 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 clause (1) or (2) of Section 6.01 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, any Subsidiary or
Subsidiary Guarantor, their creditors or their 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 6, 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 holders of Senior Indebtedness of the Company to the
     extent required by Article 10;
<PAGE>

                                                                              49

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

          FOURTH:  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 Trustee shall mail to each Securityholder and the Company a notice
that states the record date, the 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 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 principal amount of the Securities.

          SECTION 6.12.  Waiver of Stay or Extension Laws. Neither the Company
                         --------------------------------
nor any Subsidiary Guarantor (to the extent it may lawfully do so) shall 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, which may affect the covenants or the performance
of this Indenture; and the Company and each Subsidiary Guarantor (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 7

                                    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.
<PAGE>

                                                                              50

          (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;

          (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.

          (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, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

          (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.

          SECTION 7.02.  Rights of Trustee. (a)  The Trustee may conclusively
                         ------------------
rely and shall be fully protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice,
request, direction, consent, order, bond, debenture or other paper or document
believed to be genuine and to have been signed or presented by the proper party
or parties.

          (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 execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through, agents,

nominee appointed with due care by it hereunder.

          (d)  The Trustee shall not be liable for any action it takes or omits
to take in good faith which 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

          (f)  The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, debenture,
note or other paper or document unless requested in writing to do so by the
Holders of not less than a majority in principal amount of the Securities at the
time outstanding, but the Trustee, in its discretion, may 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.

          (g)  The Trustee shall not be accountable for the use by the Company
of the proceeds of the Securities.

          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-paying
agent 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 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 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 occurs and is
                         -------------------
continuing and if it is actually known to a Trust Officer, the Trustee shall
mail to each Securityholder notice of the Default within the earlier of 90 days
after it occurs or 30 days after it actually becomes known to a Trust Officer.
Except in the case of a Default in payment of principal of, premium (if any) or
interest on any Security (including payments pursuant to the mandatory
redemption provisions of such Security, if any), 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 March 1 beginning with the March 1 following the date of
this Indenture, and in any event prior to May 1 in each year, the Trustee shall
mail to each Securityholder a brief report dated as of May 1 that complies with
Section 313(a) of the TIA.  The Trustee shall also comply with Section 313(b) of
the TIA.

          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 in
writing 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, its directors, officers, employees and agents against any
and all loss, liability or expense (including reasonable attorneys' fees and
<PAGE>

                                                                              52

expenses) incurred by or in connection with the administration of this trust and
the performance of its duties hereunder.  The Trustee shall notify the Company
of any claim for which it may seek indemnity promptly upon obtaining actual
knowledge thereof; provided, however, that any failure so to notify the Company
                   --------  -------
shall not relieve the Company or any Subsidiary Guarantor of its indemnity
obligations hereunder.  The Company shall defend the claim and the indemnified
party shall provide reasonable cooperation at the Company's expense in the
defense.  Such indemnified parties may have separate counsel and the Company and
the Subsidiary Guarantors, as applicable shall pay the fees and expenses of such
counsel; provided, however, that the Company shall not be required to pay such
         --------  -------
fees and expenses if it assumes such indemnified parties' defense and, in such
indemnified parties' reasonable judgment, there is no conflict of interest
between the Company and the Subsidiary Guarantor, as applicable, and such
parties in connection with such defense.  The Company need not reimburse any
expense or indemnify against any loss, liability or expense incurred by an
indemnified party through such party's own wilful misconduct, negligence or bad
faith.

          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 and any liquidated damages on particular Securities.

          The Company's payment obligations pursuant to this Section 7.07 shall
survive the satisfaction or discharge of this Indenture, any rejection or
termination of this Indenture under any Bankruptcy Law or the resignation or
removal of the Trustee.  When the Trustee incurs expenses after the occurrence
of a Default specified in clause (7) or (8) of Section 6.01 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 principal amount
of the Securities 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;

          (4) the Trustee otherwise becomes incapable of acting; or

          (5) the Trustee increases its fees (exclusive of fees for
          extraordinary services) by more than 10% in any twelve month period.

          If the Trustee resigns, is removed by the Company or by the Holders of
a majority in principal amount of the Securities 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
<PAGE>

                                                                              53

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 principal amount of the Securities 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
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 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 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
successor to the Trustee may authenticate such Securities 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 Section 310(a) of the TIA.  The Trustee
shall have a combined capital and surplus of at least $100,000,000 as set forth
in its most recent published annual report of condition.  The Trustee shall
comply with Section 3.01(b) of the TIA; provided, however, that there shall be
                                        --------  -------
excluded from the operation of Section 3.01(b)(1) of the TIA 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 Section 3.01(b)(1) of the TIA are
met.

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

          SECTION 7.12.  Trustee Acting as Paying Agent or Registrar.  In the
                         --------------------------------------------
event that the Trustee is also acting as a Paying Agent or Registrar hereunder,
the rights and protections afforded to the Trustee pursuant to this Article 7
shall also be afforded to such Paying Agent or Registrar.

                       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 2.07) for cancelation 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 3, and the
Company irrevocably deposits with the Trustee funds or U.S. Government
Obligations on which payment of principal and interest when due will be
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 2.07), 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 and 4.14 and the
operation of Section 5.01(a)(3),  5.01(a)(4), 5.01(a)(5), 6.01(4), 6.01(6),
6.01(7) (with respect to Significant Subsidiaries of the Company only), 6.01(8)
(with respect to Significant Subsidiaries of the Company only), 6.01(10),
6.01(11) and 6.01(12)  ("covenant defeasance option").  The Company may exercise
its legal defeasance option notwithstanding its prior exercise of its covenant
defeasance option.  In the event that the Company terminates all of its
obligations under the Securities and this Indenture by exercising its legal
defeasance option or its covenant defeasance option, the obligations under the
Subsidiary Guarantees shall each be terminated simultaneously with the
termination of such obligations.

          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 Section 6.01(4),
6.01(6), 6.01(7) (with respect to Significant Subsidiaries of the Company only),
6.01(8) (with respect to Significant Subsidiaries of the Company only), 6.01(9),
6.01(10), 6.01(11) and 6.01(12) or because of the failure of the Company to
comply with clauses (3), (4) and (5) of Section 5.01(a).

          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, 2.07, 2.08, 2.09, 7.07, 7.08 and
in this Article 8 shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07, 8.04 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, premium (if
     any) and interest on the Securities to maturity or redemption, as the case
     may be;
<PAGE>

                                                                              55

          (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 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 principal 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 clause (7) or (8) of Section 6.01 with
     respect to the Company occurs which is continuing at the end of the period;

          (4) the deposit does not constitute a default under any other
     agreement binding on the Company and is not prohibited by Article 10;

          (5) 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;

          (6) 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 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 Federal
     income tax purposes as a result of such defeasance and will be subject to
     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;

          (7) 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 Federal income
     tax purposes as a result of such covenant defeasance and will be subject to
     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

          (8) 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
     8 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 3.

          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 8.  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 interest on the Securities.  Money
and securities so held in trust are not subject to Article 10.

          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 written request any money held by
them for the payment of
<PAGE>

                                                                              56

principal 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 8 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 8 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 8; 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 Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.

                                   Amendments
                                   ----------

          SECTION 9.01.  Without Consent of Holders.   (a)  Without the consent
                         ---------------------------
of any Holder of Securities, the Company, the Subsidiary Guarantors and the
Trustee may amend this Indenture to:

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

          (2) comply with Article 5;

          (3) 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) make any change in Article 10 or Article 12 that would limit or
     terminate the benefits available to any holder of Senior Indebtedness of
     the Company (or any Representative thereof) under Article 10 or Article 12;

          (5) add additional guarantees with respect to the Securities;

          (6) secure the Securities;

          (7) add to the covenants of the Company for the benefit of the
     Securityholders;

          (9) make any change that does not adversely affect the rights of any
     Securityholder;
<PAGE>

                                                                              57

          (10) provide for the issuance of the Exchange Securities or Private
     Exchange Securities, subject to the provisions of this Indenture; or

          (11) comply with any requirement of the Commission in connection with
     the qualification of this Indenture under the TIA.

          (b)  No amendment may be made under this Section 9.01, that adversely
affects the rights under Article 10 or Article 12 of any holder of Senior
Indebtedness of the Company then outstanding unless the holders of such Senior
Indebtedness (or any group or representative thereof authorized to give a
consent) consent to such change.

          (c)  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 the amendment.

          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 a
majority in aggregate principal amount of the Securities then outstanding
(including consents obtained in connection with a tender offer or exchange for
the Securities).  However, (a) without the consent of each Securityholder
affected, an amendment may not:

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

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

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

          (4) reduce the premium payable upon the redemption of any Security or
     change the time at which any Security may be redeemed in accordance with
     Article 3;

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

          (6) impair the right of any Holder of Securities to receive payment of
     principal of and interest or any liquidated damages 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

          (7) make any change in the amendment provisions which require the
     consent of each Holder of Securities or in the waiver provisions; and

          (b) without the consent of the holders of 75% in aggregate principal
amount of the Notes then outstanding, no amendment may:

          (1) make any change to the subordination provisions of this Indenture
          that adversely affects the rights of any holder of Notes; or

          (2) modify the Subsidiary Guarantee in any manner adverse to the
          holders of Notes.
<PAGE>

                                                                              58

          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.

          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.

          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 on which the Trustee receives an Officers'
Certificate from the Company certifying that the requisite number of consents
have been received. After an amendment or waiver becomes effective, it shall
bind every Securityholder. An amendment or waiver becomes effective upon the (i)
receipt by the Company or the Trustee of the requisite number of consents, (ii)
satisfaction of conditions to effectiveness as set forth in this Indenture and
any indenture supplemental hereto containing such amendment or waiver and (iii)
execution of such amendment or waiver (or supplemental indenture) by the Company
and 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 it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it 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 9 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 and that such amendment
is the legal, valid and binding obligation of the Company and the Subsidiary
Guarantors enforceable against them in accordance with its terms, subject to
customary exceptions, and complies with the provisions hereof (including Section
9.03).

          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.

          SECTION 10.01.  Agreement To Subordinate.  The Company agrees, and
                          -------------------------
each Securityholder by accepting a Security agrees, that the Indebtedness
evidenced by the Securities is unsecured Senior Subordinated Indebtedness of the
Company, is subordinated in right of payment, to the extent and in the manner
provided in this Article 10, to the prior payment in full of all existing and
future Senior Indebtedness of the Company and that the subordination is for the
benefit of and enforceable by the holders of such Senior Indebtedness.  The
Securities shall in all respects rank pari passu with all other Senior
                                      ---- -----
Subordinated Indebtedness of the Company, including the Discount Notes, and only
Indebtedness of the Company that is Senior Indebtedness of the Company shall
rank senior to the Securities in accordance with the provisions set forth
herein.  For purposes of this Article 10, the Indebtedness evidenced by the
Securities shall be deemed to include the liquidated damages payable pursuant to
the provisions set forth in the Securities and the Registration Agreement.  All
provisions of this Article 10 shall be subject to Section 10.12.

          SECTION 10.02.  Liquidation, Dissolution, Bankruptcy.  Upon any
                          -------------------------------------
payment or distribution of the assets of the Company to creditors upon a total
or partial liquidation or a total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property:

          (1) holders of Senior Indebtedness of the Company shall be entitled to
     receive payment in full of such Senior Indebtedness before Securityholders
     shall be entitled to receive any payment of principal of or interest on the
     Securities; and

          (2) until the Senior Indebtedness of the Company is paid in full, any
     payment or distribution to which Securityholders would be entitled but for
     this Article 10 shall be made to holders of such Senior Indebtedness as
     their interests may appear, except that Securityholders may receive shares
     of stock and any debt securities that are subordinated to such Senior
     Indebtedness to at least the same extent as the Securities.

          SECTION 10.03.  Default on Senior Indebtedness.  The Company may not
                          -------------------------------
pay the principal of, premium (if any) or interest on the Securities or make any
deposit pursuant to Section 8.01 and may not otherwise repurchase, redeem or
otherwise retire any Securities (collectively, "pay the Securities"), other than
payments made with money or U.S. Government Obligations previously deposited in
the defeasance trust described under Article 8,

if (i) any Designated Senior Indebtedness of the Company is not paid when due or
(ii) any other default on such Designated Senior Indebtedness occurs and the
maturity of such Designated Senior Indebtedness 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
Indebtedness has been paid in full; provided, however, that the Company may pay

occurred and is continuing. 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 Indebtedness of the Company pursuant to which the
maturity thereof may be accelerated immediately without further notice (except
such notice as may be required to effect such acceleration) or the expiration of
any applicable grace periods, the Company may not pay the Securities for a
period (a "Payment Blockage Period") commencing upon the receipt by the Trustee
(with a copy to the Company) of written notice (a "Blockage Notice") of such
default from the Representative of such Designated Senior Indebtedness
specifying an election to effect a Payment Blockage Period and ending 179 days
thereafter (or earlier if such Payment Blockage Period is terminated (i) by
written notice to the Trustee and the Company from the Person or Persons who
gave such Blockage Notice, (ii) by repayment in full of such Designated Senior
Indebtedness or (iii) because the default giving rise to such Blockage Notice is
no longer continuing). Notwithstanding the provisions described in the
immediately preceding sentence (but subject to the provisions contained in the
first sentence of this Section 10.03), unless the holders of such Designated
Senior Indebtedness or the Representative of such holders shall have accelerated
the maturity of such Designated Senior Indebtedness, the Company may resume
payments on the Securities after the end of such Payment Blockage Period. Not
more than one Blockage Notice may be given in any consecutive 360-day period,
irrespective of the number of defaults with respect to Designated Senior
Indebtedness during such period; provided, however, that if any Blockage Notice
                                 --------  -------
within such 360-day period is given by or on behalf of any holders of Designated
Senior Indebtedness other than the Bank Indebtedness, the Representative of the
Bank Indebtedness may give another Blockage Notice within such period; provided
                                                                       --------
further, however, that in no event may the total number of days during which any
-------  -------
Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate
during any 360 consecutive day period. For purposes of this Section 10.03, no
default or event of default that existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated
Senior Indebtedness initiating such Payment Blockage Period shall be, or be
made, the basis of the commencement of a subsequent Payment Blockage Period by
the Representative of such Designated Senior Indebtedness, whether or not within
a period of 360 consecutive days, unless such default or event of default shall
have been cured or waived for a period of not less than 90 consecutive days.

          SECTION 10.04.  Acceleration of Payment of Securities.  If payment of
                          --------------------------------------
the Securities is accelerated because of an Event of Default, the Company or the
Trustee shall promptly notify the holders of the Designated Senior Indebtedness
of the Company (or their Representative) of the acceleration.  If any Designated
Senior Indebtedness of the Company is outstanding, the Company may not pay the
Securities until five Business Days after such holders or the Representative of
such Designated Senior Indebtedness receive notice of such acceleration and,
thereafter, may pay the Securities only if this Article 10 otherwise permits
payment at that time.

          SECTION 10.05.  When Distribution Must Be Paid Over.  If a
                          ------------------------------------
distribution is made to Securityholders that because of this Article 10 should
not have been made to them, the Securityholders who receive the distribution
shall hold it in trust for holders of Senior Indebtedness of the Company and pay
it over to them as their interests may appear.

          SECTION 10.06.  Subrogation.  After all Senior Indebtedness of the
                          ------------
Company is paid in full and until the Securities are paid in full,
Securityholders shall be subrogated to the rights of holders of such Senior
Indebtedness to receive distributions applicable to Senior Indebtedness.  A
distribution made under this Article 10 to holders of such Senior Indebtedness
which otherwise would have been made to Securityholders is not, as between the
Company and Securityholders, a payment by the Company on such Senior
Indebtedness.

          SECTION 10.07.  Relative Rights.  This Article 10 defines the relative
                          ----------------
rights of Securityholders and holders of Senior Indebtedness of the Company.
Nothing in this Indenture shall:

          (1) impair, as between the Company and Securityholders, the obligation
     of the Company, which is absolute and unconditional, to pay principal of
     and interest on and liquidated damages in respect of, the Securities in
     accordance with their terms; or

          (2) prevent the Trustee or any Securityholder from exercising its
     available remedies upon a Default, subject to the rights of holders of
     Senior Indebtedness of the Company to receive distributions otherwise
     payable to Securityholders.

          SECTION 10.08.  Subordination May Not Be Impaired by Company.  No
                          ---------------------------------------------
right of any holder of Senior Indebtedness of the Company to enforce the
subordination of the Indebtedness evidenced by the Securities shall be impaired
by any act or failure to act by the Company or by its failure to comply with
this Indenture.

          SECTION 10.09.  Rights of Trustee and Paying Agent.  Notwithstanding
                          -----------------------------------
Section 10.03, the Trustee or Paying Agent may continue to make payments on the
Securities and shall not 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 of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article 10.  The Company, the Registrar, the Paying Agent, a Representative or a
holder of Senior Indebtedness of the Company may give the notice; provided,
                                                                  --------
however, that, if an issue of Senior Indebtedness of the Company has a
-------
Representative, only the Representative may give the notice.

          The Trustee in its individual or any other capacity may hold Senior
Indebtedness of the Company with the same rights it would have if it were not
Trustee. The 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 10
with respect to any Senior Indebtedness of the Company which may at any time be
held by it, to the same extent as any other holder of such Senior Indebtedness;
and nothing in Article 7 shall deprive the Trustee of any of its rights as such
holder. Nothing in this Article 10 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.07.

          SECTION 10.10.  Distribution or Notice to Representative.  Whenever a
                          -----------------------------------------
distribution is to be made or a notice given to holders of Senior Indebtedness
of the Company, the distribution may be made and the notice given to their
Representative (if any).

          SECTION 10.11.  Article 10 Not To Prevent Events of Default or Limit
                          ----------------------------------------------------
Right To Accelerate.  The failure to make a payment pursuant to the Securities
--------------------
by reason of any provision in this Article 10 shall not be construed as
preventing the occurrence of a Default. Nothing in this Article 10 shall have
any effect on the right of the Securityholders or the Trustee to accelerate the
maturity of the Securities.

          SECTION 10.12.  Trust Moneys Not Subordinated.  Notwithstanding
                          ------------------------------
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article 8 by the Trustee for
the payment of principal of and interest on the Securities shall not be
subordinated to the prior payment of any Senior Indebtedness of the Company or
subject to the restrictions set forth in this Article 10, and none of the
Securityholders shall be obligated to pay over any such amount to the Company or
any holder of Senior Indebtedness of the Company or any other creditor of the
Company.

          SECTION 10.13.  Trustee Entitled To Rely.  Upon any payment or
                          -------------------------
distribution pursuant to this Article 10, the Trustee and the Securityholders
shall be entitled to rely conclusively (i) upon any order or decree of a court
of competent jurisdiction in which any proceedings of the nature referred to in
Section 10.02 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 Representatives for the holders of Senior
Indebtedness of the Company for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of such Senior
Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article 10. 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 Senior Indebtedness of the Company to participate
in any payment or distribution pursuant to this Article 10, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of such Senior Indebtedness 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 10, 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 10.

          SECTION 10.14.  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
Senior Indebtedness of the Company as provided in this Article 10 and appoints
the Trustee as attorney-in-fact for any and all such purposes.

          SECTION 10.15.  Trustee Not Fiduciary for Holders of Senior
                          -------------------------------------------
Indebtedness.  The Trustee shall not be deemed to owe any fiduciary duty to the
-------------
holders of Senior Indebtedness of the Company and 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 Senior
Indebtedness of the Company shall be entitled by virtue of this Article 10 or
otherwise.

          SECTION 10.16.  Reliance by Holders of Senior Indebtedness 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 Senior
Indebtedness of the Company, whether such Senior Indebtedness was created or
acquired before or after the issuance of the Securities, to acquire and continue
to hold, or to continue to hold, such Senior Indebtedness and such holder of
such Senior Indebtedness shall be deemed conclusively to have relied on such
subordination provisions in acquiring and continuing to hold, or in continuing
to hold, such Senior Indebtedness.

          SECTION 10.17.  Trustee's Compensation Not Prejudiced.  Nothing in
                          --------------------------------------
this Article shall apply to amounts due to the Trustee pursuant to other
sections of this Indenture.

          SECTION 10.18.  Defeasance.  The terms of this Article 10 shall not
                          -----------
apply to payments from money or the proceeds of U.S. Government Obligations held
in trust by the Trustee for the payment of principal of and interest on the
Securities pursuant to the provisions described in Section 8.03.

                                   ARTICLE 11

                             Subsidiary Guarantees
                             ---------------------

          SECTION 11.01.  Subsidiary Guarantees.  Subject to the release
                          ----------------------
provisions of this Indenture, each Subsidiary Guarantor hereby jointly and
severally irrevocably and unconditionally guarantees, as a primary obligor and
not merely as a surety, to each Holder and to the Trustee and its successors and
assigns (a) the full and punctual payment when due, whether at Stated Maturity,
by acceleration, by redemption or otherwise, of all obligations of the Company
under this Indenture (including obligations to the Trustee) and the Securities,
whether for payment of principal of, interest on or liquidated damages in
respect of, the Securities 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 whether for expenses, indemnification or otherwise under this Indenture
and the Securities (all the foregoing being hereinafter collectively called the
"Guaranteed Obligations") by executing a Subsidiary Guarantee. Each Subsidiary
Guarantor further agrees that the Guaranteed Obligations may be extended or
renewed, in whole or in part, without notice or further assent from each such
Subsidiary Guarantor, and that each such Subsidiary Guarantor shall remain bound
under this Article 11 notwithstanding any extension or renewal of any Guaranteed
Obligation.

          Each Subsidiary Guarantor waives presentation to, demand of, payment
from and protest to the Company of any of the Guaranteed Obligations and also
waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice
of any default under the Securities or the Guaranteed 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 Guaranteed Obligations or any of them; (e) the failure of any Holder or
Trustee to exercise any right or remedy against any other guarantor of the
Guaranteed Obligations; or (f) any change in the ownership of such Subsidiary
Guarantor, except as provided in Section 11.02(b).

          Each Subsidiary Guarantor hereby waives any right to which it may be
entitled to have its obligations hereunder divided among the Subsidiary
Guarantors, such that such Subsidiary Guarantor's obligations would be less than
the full amount claimed. Each Subsidiary Guarantor hereby waives any right to
which it may be entitled to have the assets of the Company first be used and
depleted as payment of the Company's or such Subsidiary Guarantor's obligations
hereunder prior to any amounts being claimed from or paid by such Subsidiary
Guarantor hereunder. Each Subsidiary Guarantor hereby waives any right to which
it may be entitled to require that the Company be sued prior to an action being
initiated against such Subsidiary Guarantor.

          Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee
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 Guaranteed Obligations.

          The Subsidiary Guarantee of each Subsidiary Guarantor is, to the
extent and in the manner set forth in Article 12, subordinated and subject in
right of payment to the prior payment in full of the principal of and premium,
if any, and interest on all Senior Indebtedness of the relevant Subsidiary
Guarantor and is made subject to such provisions of this Indenture.

                                                                              64

          Except as expressly set forth in Sections 8.01(b), 11.02 and 11.06,
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, wilful or otherwise, 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 any Subsidiary Guarantor or would otherwise operate as a
discharge of any Subsidiary Guarantor as a matter of law or equity.

          Each Subsidiary Guarantor agrees that its Subsidiary Guarantee shall
remain in full force and effect until payment in full of all the Guaranteed
Obligations (except as otherwise provided in Section 8.01(b)).  Each Subsidiary
Guarantor further agrees that its Subsidiary Guarantee 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 interest on any Guaranteed 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 which any Holder or the Trustee has at law or in equity against any
Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay
the principal of or interest on any Guaranteed 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 Guaranteed Obligation, each
Subsidiary Guarantor hereby promises to and shall, 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 principal
amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such
Guaranteed 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 relation to the Holders in respect of any Guaranteed
Obligations guaranteed hereby until payment in full of all Guaranteed
Obligations and all obligations to which the Guaranteed Obligations are
subordinated as provided in Article 12.  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 Guaranteed Obligations guaranteed hereby
may be accelerated as provided in Article 6 for the purposes of any Subsidiary
Guarantee herein, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Guaranteed Obligations guaranteed
hereby, and (y) in the event of any declaration of acceleration of such
Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations
(whether or not due and payable) shall forthwith become due and payable by such
Subsidiary Guarantor for the purposes of this Section 11.01.

          Each Subsidiary Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees and expenses) incurred by the
Trustee or any Holder in enforcing any rights under this Section 11.01.

          Upon request of the Trustee, each Subsidiary Guarantor 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.

                          ------------------------
of this Indenture to the contrary notwithstanding, the maximum, aggregate amount
of the Guaranteed Obligations guaranteed hereunder by any Subsidiary Guarantor
shall not exceed the maximum amount that can be hereby guaranteed without
rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

          (b)  A Subsidiary Guarantee as to any Subsidiary Guarantor shall
terminate and be of no further force or effect and such Subsidiary Guarantor
shall be deemed to be released from all obligations under this Article 11 (i) in
the event that such Subsidiary Guarantor no longer has outstanding, other than
the Subsidiary Guarantee, any Indebtedness (in the case of a Domestic Restricted
Subsidiary) or Material Indebtedness (in the case of a Foreign Restricted
Subsidiary) or (ii) upon (x) the merger or consolidation of such Subsidiary
Guarantor with or into any Person other than the Company or a Subsidiary or
Affiliate of the Company where such Subsidiary Guarantor is not the surviving
entity of such consolidation or merger or (y) the sale by the Company or any
Subsidiary of the Company (or any pledgee of the Company) of a majority of the
Capital Stock of such Subsidiary Guarantor, where, after such sale, such
Subsidiary Guarantor is no longer a Subsidiary of the Company; provided,

however, that each such merger, consolidation or sale (or, in the case of a sale
-------
by such a pledgee, the disposition of the proceeds of such sale) shall comply
with Section 4.06 and Section 5.01(b).  At the written request of the Company,
the Trustee shall execute and deliver an appropriate instrument evidencing such
release.

          SECTION 11.03.  Successors and Assigns.  This Article 11 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 11.04.  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 11 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 which either may have under this Article 11 at law,
in equity, by statute or otherwise.

          SECTION 11.05.  Modification.  No modification, amendment or waiver of
                          -------------
any provision of this Article 11, 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 11.06.  Execution of Supplemental Indenture for Future
                          ----------------------------------------------
Subsidiary Guarantors.  Each Subsidiary which is required to become a Subsidiary
----------------------
Guarantor pursuant to Section 4.11 shall promptly execute and deliver to the
Trustee a supplemental indenture in the form of Exhibit C hereto pursuant to
which such Subsidiary shall become a Subsidiary Guarantor under this Article 11
and shall guarantee the Guaranteed Obligations.  Concurrently with the execution
and delivery of such supplemental indenture, the Company shall deliver to the
Trustee an Opinion of Counsel and an Officers' Certificate 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 Guarantee of such Subsidiary Guarantor is a legal, valid

Subsidiary Guarantor in accordance with its terms.

                   Subordination of the Subsidiary Guarantees
                   ------------------------------------------

                          ------------------------
agrees, and each Securityholder by accepting a Security agrees, that the
obligations of a Subsidiary Guarantor hereunder are subordinated in right of
payment, to the extent and in the manner provided in this Article 12, to the
prior payment in full of all existing and future Senior Indebtedness of such
Subsidiary Guarantor and that the subordination is for the benefit of and
enforceable by the holders of such Senior Indebtedness of such Subsidiary
Guarantor.  The obligations hereunder with respect to a Subsidiary Guarantor
shall in all respects rank pari passu with all other Senior Subordinated
                           ---- -----
Indebtedness of such Subsidiary Guarantor and shall rank senior to all existing
and future Subordinated Obligations of such Subsidiary Guarantor; and only
Indebtedness of such Subsidiary Guarantor that is Senior Indebtedness of such
Subsidiary Guarantor shall rank senior to the obligations of such Subsidiary
Guarantor in accordance with the provisions set forth herein.

Subsidiary Guarantor or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to such Subsidiary Guarantor and its
properties:

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

          (2) until the Senior Indebtedness of such Subsidiary Guarantor is paid
     in full, any payment or distribution to which Securityholders would be
     entitled but for this Article 12 shall be made to holders of such Senior
     Indebtedness as their respective interests may appear, except that
     Securityholders may receive shares of stock and any debt securities that
     are subordinated to such Senior Indebtedness to at least the same extent as
     the Guarantees.

          SECTION 12.03.  Default on Designated Senior Indebtedness of a

Indebtedness of such Subsidiary Guarantor is not paid when due or (ii) any other

continuing. 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 Indebtedness of a Subsidiary Guarantor pursuant to which the
maturity thereof may be accelerated immediately without further notice (except
such notice as may be required to effect such acceleration) or the expiration of
any applicable grace periods, such Subsidiary Guarantor may not pay its
Guarantee for a Payment Blockage Period commencing upon the receipt by the
Trustee (with a copy to such Subsidiary Guarantor and the Company) of a Blockage
Notice of such default from the Representative of the holders of the Designated
Senior Indebtedness of such Subsidiary Guarantor specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter (or earlier if
such Payment Blockage Period is terminated (i) by written notice to the Trustee
(with a copy to such Subsidiary Guarantor and the Company) from the Person or
Persons who gave such Blockage Notice, (ii) because such Designated Senior
Indebtedness has been repaid in full or (iii) because the default giving rise to
such Blockage Notice is no longer continuing). Notwithstanding the provisions
described in the immediately preceding sentence (but subject to the provisions
contained in the first sentence of this Section 12.03), unless the holders of
such Designated Senior Indebtedness or the Representative of such holders shall
have accelerated the maturity of such Designated Senior Indebtedness, such
Subsidiary Guarantor may resume paying its Guarantee after such Payment Blockage
Period, including any missed payments. Not more than one Blockage Notice may be
given with respect to a Subsidiary Guarantor in any consecutive 360-day period,
irrespective of the number of defaults with respect to Designated Senior
Indebtedness of such Subsidiary Guarantor during such period.

          SECTION 12.04.  Demand for Payment.  If payment of the Securities is
                          -------------------
accelerated because of an Event of Default and a demand for payment is made on a
Subsidiary Guarantor pursuant to Article 11, the Trustee shall promptly notify
the holders of the Designated Senior Indebtedness of such Subsidiary Guarantor
(or the Representative of such holders) of such demand.  If any Designated
Senior Indebtedness of such Subsidiary Guarantor is outstanding, such Subsidiary
Guarantor may not pay its Guarantee until five Business Days after such holders
or the Representative of the holders of the Designated Senior Indebtedness of
such Subsidiary Guarantor receive notice of such demand and, thereafter, may pay
its Guarantee only if this Article 12 otherwise permits payment at that time.

          SECTION 12.05.  When Distribution Must Be Paid Over.  If a payment or
                          ------------------------------------
distribution is made to Securityholders that because of this Article 12 should
not have been made to them, the Securityholders who receive the payment or
distribution shall hold such payment or distribution in trust for holders of the
Senior Indebtedness of the relevant Subsidiary Guarantor and pay it over to them
as their respective interests may appear.

          SECTION 12.06.  Subrogation.  After all Senior Indebtedness of a
                          ------------
Subsidiary Guarantor is paid in full and until the Securities are paid in full
in cash, Securityholders shall be subrogated to the rights of holders of Senior
Indebtedness of such Subsidiary Guarantor to receive distributions applicable to
Designated Senior Indebtedness of such Subsidiary Guarantor.  A distribution
made under this Article 12 to holders of Senior Indebtedness of such Subsidiary
Guarantor which otherwise would have been made to Securityholders is not, as
between such Subsidiary Guarantor and Securityholders, a payment by such
Subsidiary Guarantor on Senior Indebtedness of such Subsidiary Guarantor.

          SECTION 12.07.  Relative Rights.  This Article 12 defines the relative
                          ----------------
rights of Securityholders and holders of Senior Indebtedness of a Subsidiary
Guarantor.  Nothing in this Indenture shall:

          (1) impair, as between a Subsidiary Guarantor and Securityholders, the
     obligation of a Subsidiary Guarantor which is absolute and unconditional,
     to make payments with respect to the Guaranteed Obligations to the extent
     set forth in Article 11; or
<PAGE>

                                                                              68

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

          SECTION 12.08.  Subordination May Not Be Impaired by a Subsidiary
                          --------------------------------------------------
Guarantor.  No right of any holder of Senior Indebtedness of a Subsidiary
----------
Guarantor to enforce the subordination of the obligations of such Subsidiary
Guarantor hereunder shall be impaired by any act or failure to act by such
Subsidiary Guarantor or by its failure to comply with this Indenture.

          SECTION 12.09.  Rights of Trustee and Paying Agent.  Notwithstanding
                          -----------------------------------
Section 12.03, the Trustee or the Paying Agent may continue to make payments on
the Securities and shall not 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 of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article 12.  A Subsidiary Guarantor, the Registrar or co-registrar, the Paying
Agent, a Representative or a holder of Senior Indebtedness of a Subsidiary
Guarantor may give the notice; provided, however, that if an issue of Senior
                               --------  -------
Indebtedness of a Subsidiary Guarantor has a Representative, only the
Representative may give the notice.

          The Trustee in its individual or any other capacity may hold Senior
Indebtedness of a Subsidiary Guarantor 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 12 with respect to any Senior Indebtedness of a Subsidiary
Guarantor which may at any time be held by it, to the same extent as any other
holder of Senior Indebtedness of such Subsidiary Guarantor; and nothing in
Article 7 shall deprive the Trustee of any of its rights as such holder.
Nothing in this Article 12 shall apply to claims of, or payments to, the Trustee
under or pursuant to Section 7.07.

          SECTION 12.10.  Distribution or Notice to Representative.  Whenever a
                          -----------------------------------------
distribution is to be made or a notice given to holders of Senior Indebtedness
of a Subsidiary Guarantor, the distribution may be made and the notice given to
their Representative (if any).

          SECTION 12.11.  Article 12 Not To Prevent Events of Default or Limit
                          ----------------------------------------------------
Right To Accelerate.  The failure of a Subsidiary Guarantor to make a payment on
--------------------
any of its obligations by reason of any provision in this Article 12 shall not
be construed as preventing the occurrence of a default by such Subsidiary
Guarantor under such obligations.  Nothing in this Article 12 shall have any
effect on the right of the Securityholders or the Trustee to make a demand for
payment on a Subsidiary Guarantor pursuant to Article 11.

          SECTION 12.12.  Trustee Entitled To Rely.  Upon any payment or
                          -------------------------
distribution pursuant to this Article 12, the Trustee and the Securityholders
shall be entitled to rely conclusively (i) upon any order or decree of a court
of competent jurisdiction in which any proceedings of the nature referred to in
Section 12.02 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 Representatives for the holders of Senior
Indebtedness of a Subsidiary Guarantor for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
the Senior Indebtedness of a Subsidiary Guarantor and other Indebtedness of a
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 12.  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
Senior Indebtedness of a Subsidiary Guarantor to participate in any payment or
distribution pursuant to this Article 12, the Trustee may request such Person to

furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of Senior Indebtedness 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 12, 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 12.

          SECTION 12.13.  Trustee To Effectuate Subordination.  Each
                          ------------------------------------
Securityholder by accepting a Security authorizes and directs the Trustee on his
or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination between the Securityholders and the
holders of Senior Indebtedness of each of the Subsidiary Guarantors as provided
in this Article 12 and appoints the Trustee as attorney-in-fact for any and all
such purposes.

          SECTION 12.14.  Trustee Not Fiduciary for Holders of Senior
                          -------------------------------------------
Indebtedness of a Subsidiary Guarantor.  The Trustee shall not be deemed to owe
---------------------------------------
any fiduciary duty to the holders of Senior Indebtedness of a Subsidiary
Guarantor and shall not be liable to any such holders if it shall mistakenly pay
over or distribute to Securityholders or the relevant Subsidiary Guarantor or
any other Person, money or assets to which any holders of Senior Indebtedness of
such Subsidiary Guarantor shall be entitled by virtue of this Article 12 or
otherwise.

          SECTION 12.15.  Reliance by Holders of Senior Indebtedness of a
                          -----------------------------------------------
Subsidiary Guarantor 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 Senior Indebtedness of a Subsidiary Guarantor, whether such
Senior Indebtedness was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, or to continue to hold, such Senior
Indebtedness and such holder of Senior Indebtedness shall be deemed conclusively
to have relied on such subordination provisions in acquiring and continuing to
hold, or in continuing to hold, such Senior Indebtedness.

          SECTION 12.16.  Defeasance.  The terms of this Article 12 shall not
                          -----------
apply to payments from money or the proceeds of U.S. Government Obligations held
in trust by the Trustee for the payment of principal of and interest on the
Securities pursuant to the provisions described in Section 8.03.

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

          SECTION 13.01. Satisfaction and Discharge of Indenture. This Indenture
                         ---------------------------------------
shall be discharged and shall cease to be of further effect (except as to
surviving rights of registration of transfer or exchange of Securities as
expressly provided for herein) as to all outstanding Securities hereunder, and
the Trustee, upon Company Request and at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture, when

          (a) either (1) all such Securities theretofore authenticated and
delivered (other than lost, stolen or destroyed Securities which have been
replaced or paid as provided in Section 2.07) have been delivered to the Trustee
for cancellation; or (2) all Securities not theretofore delivered to the Trustee
for cancellation (x) have become due and payable, (y) will become due and
payable at their Stated Maturity within one year, or (z) are to be called for
redemption within

of redemption by the Trustee in the name, and at the expense, of the Company;
and the Company or any Subsidiary Guarantor has irrevocably deposited or caused
to be deposited with the Trustee as trust funds in trust an amount in United
States dollars or direct obligations of, or obligations the principal of and
interest on which are unconditionally guaranteed by, the United States of
America (or by any agency thereof to the extent such obligations are backed by
the full faith and credit of the United States of America), in each case
maturing prior to the date the Securities have become due and payable, the
Stated Maturity of the Securities or the relevant redemption date for the Notes,
as the case may be, sufficient to pay and discharge the entire Indebtedness on
the Securities not theretofore delivered to the Trustee for cancellation,
including the principal of, premium, if any, and accrued interest at maturity,
Stated Maturity or redemption date;

          (b) the Company or any Subsidiary Guarantor has paid or caused to be
paid all other sums payable hereunder by the Company and any Subsidiary
Guarantor; and

          (c) the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that (i) all conditions precedent herein
relating to the satisfaction and discharge hereof have been complied with and
(ii) such satisfaction and discharge will not result in a breach or violation
of, or constitute a default under, this Indenture or any other material
agreement or instrument to which the Company, any Subsidiary Guarantor or any
Subsidiary is a party or by which the Company, any Subsidiary Guarantor or any
of the Company's Subsidiaries is bound.

          Notwithstanding the satisfaction and discharge hereof, the obligations
of the Company to the Trustee under Section 7.07 and, if United States dollars
shall have been deposited with the Trustee pursuant to subclause (2) of
subsection (a) of this Section 13.01, the obligations of the Trustee under
Section 13.02 shall survive.

                         --------------------------
of the last paragraph of Section 2.04, all United States dollars deposited with
the Trustee pursuant to Section 13.1 shall be held in trust and applied by it,
in accordance with the provisions of the Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal of, premium, if any, and interest on, the
Securities for whose payment such United States dollars have been deposited with
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

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

          SECTION 12.01.  Agreement To Subordinate.  Each Subsidiary Guarantor
                          ------------------------
agrees, and each Securityholder by accepting a Security agrees, that the
obligations of a Subsidiary Guarantor hereunder are subordinated in right of
payment, to the extent and in the manner provided in this Article 12, to the
prior payment in full of all Senior Indebtedness of such Subsidiary Guarantor
and that the subordination is for the benefit of and enforceable by the holders
of such Senior Indebtedness of such Subsidiary Guarantor. The obligations
hereunder with respect to a Subsidiary Guarantor shall in all respects rank pari
                                                                            ----
passu with all other Senior Subordinated Indebtedness of such Subsidiary
-----
Guarantor and shall rank senior to all existing and future Subordinated
Obligations of such Subsidiary Guarantor; and only Indebtedness of such
Subsidiary Guarantor that is Senior Indebtedness of such Subsidiary Guarantor
shall rank senior to the obligations of such Subsidiary Guarantor in accordance
with the provisions set forth herein.

          SECTION 12.02.  Liquidation, Dissolution, Bankruptcy. Upon any payment
                          ------------------------------------
or distribution of the assets of a 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 and its
properties:

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

          (2)  until the Senior Indebtedness of such Subsidiary Guarantor is
     paid in full, any payment or distribution to which Securityholders would be
     entitled but for this Article 12 shall be made to holders of such Senior
     Indebtedness as their respective interests may appear, except that
     Securityholders may receive shares of stock and any debt securities that
     are subordinated to such Senior Indebtedness to at least the same extent as
     the Guarantees.

          SECTION 12.03.  Default on Designated Senior Indebtedness of a
                          ----------------------------------------------
Subsidiary Guarantor.  A Subsidiary Guarantor may not make any payment pursuant
--------------------
to any of the Guaranteed Obligations or repurchase, redeem or otherwise retire
any Securities (collectively, "pay its Guarantee") if (i) any Designated Senior
Indebtedness of such Subsidiary Guarantor is not paid when due or (ii) any other
default on Designated Senior Indebtedness of such Subsidiary Guarantor occurs
and the maturity of such Designated Senior Indebtedness 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 Indebtedness has been paid in full; provided, however, that such
                                           --------  -------
Subsidiary Guarantor may pay its Guarantee without regard to the foregoing if
such Subsidiary Guarantor and the Trustee receive written notice approving such
payment from the Representative of the holders of such Designated Senior
Indebtedness with respect to which either of the events in clause (i) or (ii) of
this sentence has occurred and is

                                      -75-
<PAGE>

continuing. 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 Indebtedness of a Subsidiary Guarantor pursuant to which the
maturity thereof may be accelerated immediately without further notice (except
such notice as may be required to effect such acceleration) or the expiration of
any applicable grace periods, such Subsidiary Guarantor may not pay its
Guarantee for a Payment Blockage Period commencing upon the receipt by the
Trustee (with a copy to such Subsidiary Guarantor and the Company) of a Blockage
Notice of such default from the Representative of the holders of the Designated
Senior Indebtedness of such Subsidiary Guarantor specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter (or earlier if
such Payment Blockage Period is terminated (i) by written notice to the Trustee
(with a copy to such Subsidiary Guarantor and the Company) from the Person or
Persons who gave such Blockage Notice, (ii) because such Designated Senior
Indebtedness has been repaid in full or (iii) because the default giving rise to
such Blockage Notice is no longer continuing). Notwithstanding the provisions
described in the immediately preceding sentence (but subject to the provisions
contained in the first sentence of this Section 12.03), unless the holders of
such Designated Senior Indebtedness or the Representative of such holders shall
have accelerated the maturity of such Designated Senior Indebtedness, such
Subsidiary Guarantor may resume paying its Guarantee after such Payment Blockage
Period, including any missed payments. Not more than one Blockage Notice may be
given with respect to a Subsidiary Guarantor in any consecutive 360-day period,
irrespective of the number of defaults with respect to Designated Senior
Indebtedness of such Subsidiary Guarantor during such period.

          SECTION 12.04.  Demand for Payment.  If payment of the Securities is
                          ------------------
accelerated because of an Event of Default and a demand for payment is made on a
Subsidiary Guarantor pursuant to Article 11, the Trustee shall promptly notify
the holders of the Designated Senior Indebtedness of such Subsidiary Guarantor
(or the Representative of such holders) of such demand.  If any Designated
Senior Indebtedness of such Subsidiary Guarantor is outstanding, such Subsidiary
Guarantor may not pay its Guarantee until five Business Days after such holders
or the Representative of the holders of the Designated Senior Indebtedness of
such Subsidiary Guarantor receive notice of such demand and, thereafter, may pay
its Guarantee only if this Article 12 otherwise permits payment at that time.

          SECTION 12.05.  When Distribution Must Be Paid Over. If a payment or
                          -----------------------------------
distribution is made to Securityholders that because of this Article 12 should
not have been made to them, the Securityholders who receive the payment or
distribution shall hold such payment or distribution in trust for holders of the
Senior Indebtedness of the relevant Subsidiary Guarantor and pay it over to them
as their respective interests may appear.

          SECTION 12.06.  Subrogation. After all Senior Indebtedness of a
                          -----------
Subsidiary Guarantor is paid in full and until the Securities are paid in full
in cash, Securityholders shall be subrogated to the rights of holders of Senior
Indebtedness of such Subsidiary Guarantor to receive distributions applicable to
Designated Senior Indebtedness of such Subsidiary Guarantor. A distribution made
under this Article 12 to holders of Senior Indebtedness of such Subsidiary
Guarantor which otherwise would have been made to Securityholders is not, as
between such Subsidiary Guarantor and Securityholders, a payment by such
Subsidiary Guarantor on Senior Indebtedness of such Subsidiary Guarantor.

          SECTION 12.07.  Relative Rights. This Article 12 defines the relative
                          ---------------
rights of Securityholders and holders of Senior Indebtedness of a Subsidiary
Guarantor. Nothing in this Indenture shall:

          (1)  impair, as between a Subsidiary Guarantor and Securityholders,
     the obligation of a Subsidiary Guarantor which is absolute and
     unconditional, to make payments with respect to the Guaranteed Obligations
     to the extent set forth in Article 11; or

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

          SECTION 12.08.  Subordination May Not Be Impaired by a Subsidiary
                          -------------------------------------------------
Guarantor.  No right of any holder of Senior Indebtedness of a Subsidiary
---------
Guarantor to enforce the subordination of the obligations of such Subsidiary
Guarantor hereunder shall be impaired by any act or failure to act by such
Subsidiary Guarantor or by its failure to comply with this Indenture.

          SECTION 12.09.  Rights of Trustee and Paying Agent.  Notwithstanding
                          ----------------------------------
Section 12.03, the Trustee or the Paying Agent may continue to make payments on
the Securities and shall not 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 of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article 12. A Subsidiary Guarantor, the Registrar or co-registrar, the Paying
Agent, a Representative or a holder of Senior Indebtedness of a Subsidiary
Guarantor may give the notice; provided, however, that if an issue of Senior
                               --------  -------
Indebtedness of a Subsidiary Guarantor has a Representative, only the
Representative may give the notice.

          The Trustee in its individual or any other capacity may hold Senior
Indebtedness of a Subsidiary Guarantor 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 12 with respect to any Senior Indebtedness of a Subsidiary
Guarantor which may at any time be held by it, to the same extent as any other
holder of Senior Indebtedness of such Subsidiary Guarantor; and nothing in
Article 7 shall deprive the Trustee of any of its rights as such holder. Nothing
in this Article 12 shall apply to claims of, or payments to, the Trustee under
or pursuant to Section 7.07.

          SECTION 12.10.  Distribution or Notice to Representative. Whenever a
                          ----------------------------------------
distribution is to be made or a notice given to holders of Senior Indebtedness
of a Subsidiary Guarantor, the distribution may be made and the notice given to
their Representative (if any).

          SECTION 12.11.  Article 12 Not To Prevent Events of Default or Limit
                          ----------------------------------------------------
Right To Accelerate.  The failure of a Subsidiary Guarantor to make a payment on
-------------------
any of its obligations by reason of any provision in this Article 12 shall not
be construed as preventing the occurrence of a default by such Subsidiary
Guarantor under such obligations. Nothing in this Article 12

                                      -77-
<PAGE>

shall have any effect on the right of the Securityholders or the Trustee to make
a demand for payment on a Subsidiary Guarantor pursuant to Article 11.

          SECTION 12.12.  Trustee Entitled To Rely. Upon any payment or
                          ------------------------
distribution pursuant to this Article 12, the Trustee and the Securityholders
shall be entitled to rely conclusively (i) upon any order or decree of a court
of competent jurisdiction in which any proceedings of the nature referred to in
Section 12.02 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 Representatives for the holders of Senior
Indebtedness of a Subsidiary Guarantor for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
the Senior Indebtedness of a Subsidiary Guarantor and other Indebtedness of a
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 12. 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
Senior Indebtedness of a Subsidiary Guarantor to participate in any payment or
distribution pursuant to this Article 12, the Trustee may request such Person to
furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of Senior Indebtedness 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 12, 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 12.

          SECTION 12.13.  Trustee To Effectuate Subordination. Each
                          -----------------------------------
Securityholder by accepting a Security authorizes and directs the Trustee on his
or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination between the Securityholders and the
holders of Senior Indebtedness of each of the Subsidiary Guarantors as provided
in this Article 12 and appoints the Trustee as attorney-in-fact for any and all
such purposes.

          SECTION 12.14.  Trustee Not Fiduciary for Holders of Senior
                          -------------------------------------------
Indebtedness of a Subsidiary Guarantor.  The Trustee shall not be deemed to owe
--------------------------------------
any fiduciary duty to the holders of Senior Indebtedness of a Subsidiary
Guarantor and shall not be liable to any such holders if it shall mistakenly pay
over or distribute to Securityholders or the relevant Subsidiary Guarantor or
any other Person, money or assets to which any holders of Senior Indebtedness of
such Subsidiary Guarantor shall be entitled by virtue of this Article 12 or
otherwise.

          SECTION 12.15.  Reliance by Holders of Senior Indebtedness of a
                          -----------------------------------------------
Subsidiary Guarantor 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 Senior Indebtedness of a Subsidiary Guarantor, whether such
Senior Indebtedness was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, or to continue to hold, such Senior
Indebtedness and such holder of Senior Indebtedness shall be deemed conclusively
to have relied on such subordination provisions in acquiring and continuing to
hold, or in continuing to hold, such Senior Indebtedness.

          SECTION 12.16.  Defeasance.  The terms of this Article 12 shall not
                          ----------
apply to payments from money or the proceeds of U.S. Government Obligations held
in trust by the Trustee for the payment of principal of and interest on the
Securities pursuant to the provisions described in Section 8.03.

                                  ARTICLE 13

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

          SECTION 13.01.  Satisfaction and Discharge of Indenture. This
                          ---------------------------------------
Indenture shall be discharged and shall cease to be of further effect (except as
to surviving rights of registration of transfer or exchange of Securities as
expressly provided for herein) as to all outstanding Securities hereunder, and
the Trustee, upon Company Request and at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture, when

          (a)  either (1) all such Securities theretofore authenticated and
delivered (other than lost, stolen or destroyed Securities which have been
replaced or paid as provided in Section 2.07) have been delivered to the Trustee
for cancellation; or (2) all Securities not theretofore delivered to the Trustee
for cancellation (x) have become due and payable, (y) will become due and
payable at their Stated Maturity within one year, or (z) are to be called for
redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption by the Trustee in the name, and at the
expense, of the Company; and the Company or any Subsidiary Guarantor has
irrevocably deposited or caused to be deposited with the Trustee as trust funds
in trust an amount in United States dollars or direct obligations of, or
obligations the principal of and interest on which are unconditionally
guaranteed by, the United States of America (or by any agency thereof to the
extent such obligations are backed by the full faith and credit of the United
States of America), in each case maturing prior to the date the Securities have
become due and payable, the Stated Maturity of the Securities or the relevant
redemption date for the Notes, as the case may be, sufficient to pay and
discharge the entire Indebtedness on the Securities not theretofore delivered to
the Trustee for cancellation, including the principal of, premium, if any, and
accrued interest at maturity, Stated Maturity or redemption date;

          (b)  the Company or any Subsidiary Guarantor has paid or caused to be
paid all other sums payable hereunder by the Company and any Subsidiary
Guarantor; and

          (c)  the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that (i) all conditions precedent herein
relating to the satisfaction and discharge hereof have been complied with and
(ii) such satisfaction and discharge will not result in a breach or violation
of, or constitute a default under, this Indenture or any other material
agreement or instrument to which the Company, any Subsidiary Guarantor or any
Subsidiary is a party or by which the Company, any Subsidiary Guarantor or any
of the Company's Subsidiaries is bound.

          Notwithstanding the satisfaction and discharge hereof, the obligations
of the Company to the Trustee under Section 7.07 and, if United States dollars
shall have been

                                      -79-

deposited with the Trustee pursuant to subclause (2) of subsection (a) of this

acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal of, premium, if any, and interest on, the
Securities for whose payment such United States dollars have been deposited with
the Trustee.

Security except upon satisfaction of the requirements set forth below. Upon
receipt by the Trustee of a Definitive Security, duly endorsed or accompanied by
a written instrument of transfer in form reasonably satisfactory to the Company
and the Registrar, together with:

          (i)  certification (in the form set forth on the reverse side of the
    Initial Security) that such Definitive Security is being transferred (A) to
    a QIB in accordance with Rule 144A, (B) to an IAI that has furnished to the
    Trustee a signed letter substantially in the form of Exhibit D or (C)
    outside the United States in an offshore transaction within the meaning of
    Regulation S and in compliance with Rule 904 under the Securities Act; and

          (ii) written instructions directing the Trustee to make, or to direct
    the Securities Custodian to make, an adjustment on its books and records
    with respect to such Global Security to reflect an increase in the aggregate
    principal amount of the Securities represented by the Global Security, such
    instructions to contain information regarding the Depositary account to be
    credited with such increase,

then the Trustee shall cancel such Definitive Security and cause, or direct the
Securities Custodian to cause, in accordance with the standing instructions and
procedures existing between the Depositary and the Securities Custodian, the
aggregate principal amount of Securities represented by the Global Security to
be increased by the aggregate principal amount of the Definitive Security to be
exchanged and shall credit or cause to be credited to the account of the Person
specified in such instructions a beneficial interest in the Global Security

Global Securities are then outstanding and the Global Security has not been
previously exchanged for certificated securities pursuant to Section 2.4, the
Company shall issue and the Trustee shall authenticate, upon written order of
the Company in the form of an Officers' Certificate, a new Global Security in
the appropriate principal amount.

          (c)  Transfer and Exchange of Global Securities.  (i)  The transfer
               -------------------------------------------
and exchange of Global Securities or beneficial interests therein shall be
effected through the Depositary, in accordance with this Indenture (including
applicable restrictions on transfer set forth herein, if any) and the procedures
of the Depositary therefor.  A transferor of a beneficial interest in a Global
Security shall deliver a written order given in accordance with the Depositary's
procedures containing information regarding the participant account of the
Depositary 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
account of the Person making the transfer shall be debited by an amount equal to
the beneficial interest in the Global Security being transferred.  Transfers by
an owner of a beneficial interest in the Rule 144A Global Security or the IAI
Global Security to a transferee who takes delivery of such interest through the
Regulation S Global Security, whether before or after the expiration of the
Restricted Period, shall be made only upon receipt by the Trustee of a
certification from the transferor to the effect that such transfer is being made
in accordance with Regulation S or (if available) Rule 144 under the Securities
Act and that, if such transfer is being made prior to the expiration of the
Restricted Period, the interest transferred shall be held immediately thereafter
through Euroclear or Cedel.  In the case of a transfer of a beneficial interest
in either the Regulation S Global Security or the Rule 144A Global Security for
an interest in the IAI Global Security, the transferee must furnish a signed
letter substantially in the form of Exhibit D to the Trustee.

          (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 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 shall reflect on its
    books and records
<PAGE>

                                                                               6

    the date and a corresponding decrease in the principal amount of Global
    Security from which such interest is being transferred.

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

          (iv)  In the event that a Global Security is exchanged for Definitive
    Securities pursuant to Section 2.4 prior to the consummation of the
    Registered Exchange Offer or the effectiveness of the Shelf Registration
    Statement with respect to such Securities, such Securities may be exchanged
    only in accordance with such procedures as are substantially consistent with
    the provisions of this Section 2.3 (including the certification requirements
    set forth on the reverse of the Initial Securities intended to ensure that
    such transfers comply with Rule 144A, Regulation S or such other applicable
    exemption from registration under the Securities Act, as the case may be)
    and such other procedures as may from time to time be adopted by the
    Company.

Security may only be sold, pledged or transferred through Euroclear or Cedel in

by an owner of a beneficial interest in the Regulation S Global Security to a
transferee who takes delivery of such interest through the Rule 144A Global
Security or the IAI Global Security shall be made only in accordance with
Applicable Procedures and upon receipt by the Trustee of a written certification
from the transferor of the beneficial interest in the form provided on the
reverse of the Initial Security to the effect that such transfer is being made
to (i) a person whom the transferor reasonably believes is a QIB within the
meaning of Rule 144A in a transaction meeting the requirements of Rule 144A or
(ii) an IAI purchasing for its own account, or for the account of such an IAI,
in a minimum principal amount of the Securities of $250,000.  Such written
certification shall no longer be required after the expiration of the Restricted
Period.  In the case of a transfer of a beneficial interest in the Regulation S
Global Security for an interest in the IAI Global Security, the transferee must
furnish a signed letter substantially in the form of Exhibit D to the Trustee.

          (ii)  Upon the expiration of the Restricted Period, beneficial
    ownership interests in the Regulation S Global Security shall be
    transferable in accordance with applicable law and the other terms of this
    Indenture.

                                                                               8

Each Definitive Security shall bear the following additional legend:

    "IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR
AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER
AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE
FOREGOING RESTRICTIONS."

          (ii)  Upon any sale or transfer of a Transfer Restricted Security that
    is a Definitive Security, the Registrar shall permit the Holder thereof to
    exchange such Transfer Restricted Security for a Definitive Security that
    does not bear the legends set forth above and rescind any restriction on the
    transfer of such Transfer Restricted Security if the Holder certifies in
    writing to the Registrar that its request for such exchange was made in
    reliance on Rule 144 (such certification to be in the form set forth on the
    reverse of the Initial Security).

          (iii) After a transfer of any Initial Securities or Private Exchange
    Securities during the period of the effectiveness of a Shelf Registration
    Statement with respect to such Initial Securities or Private Exchange
    Securities, as the case may be, all requirements pertaining to the
    Restricted Securities Legend on such Initial Securities or such Private
    Exchange Securities shall cease to apply and the requirements that any such
    Initial Securities or such Private Exchange Securities be issued in global
    form shall continue to apply.

          (iv)  Upon the consummation of a Registered Exchange Offer with
    respect to the Initial Securities pursuant to which Holders of such Initial
    Securities are offered Exchange Securities in exchange for their Initial
    Securities, all requirements pertaining to Initial Securities that Initial
    Securities be issued in global form shall continue to apply, and Exchange
    Securities in global form without the Restricted Securities Legend shall be
    available to Holders that exchange such Initial Securities in such
    Registered Exchange Offer.

          (v)   Upon the consummation of a Private Exchange with respect to the
    Initial Securities pursuant to which Holders of such Initial Securities are
    offered Private Exchange Securities in exchange for their Initial
    Securities, all requirements pertaining to such Initial Securities that
    Initial Securities be issued in global form shall continue to apply, and
    Private Exchange Securities in global form with the Restricted Securities
    Legend shall be available to Holders that exchange such Initial Securities
    in such Private Exchange.

          (vi)  Upon a sale or transfer after the expiration of the Restricted
    Period of any Initial Security acquired pursuant to Regulation S, all
    requirements that such Initial Security bear the Restricted Securities
    Legend shall cease to apply and the requirements requiring any such Initial
    Security be issued in global form shall continue to apply.

          (f)   Cancelation 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 Depositary to the Trustee for
cancelation or retained and canceled by the Trustee.  At any time prior to such
cancelation, 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.

    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.

1.  Interest
    --------

          (a) TeleCorp PCS, 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 shall pay
interest semiannually on January 15 and July 15 of each year commencing on
January 15, 2001. Interest on the Securities shall accrue from the most recent
date to which interest has been paid or, if no interest has been paid or duly
provided for, from July 14, 2000 until the principal hereof is due.  Interest
shall be computed on the basis of a 360-day year of twelve 30-day months.  The
Company shall pay cash 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 same rate to the extent lawful.

          (b) Liquidated Damages.  The holder of this Security is entitled to
              ------------------
the benefits of an Exchange and Registration Rights Agreement, dated as of July
14, 2000, among the Company, TeleCorp Communications, Inc. (the "Subsidiary
Guarantor") and the Initial Purchasers named therein (the "Registration
Agreement").  Capitalized terms used in this paragraph (b) but not defined
herein have the meanings assigned to them in the Registration Agreement.  If (i)
the Shelf Registration Statement or Exchange Offer Registration Statement, as
applicable under the Registration Agreement, is not filed with the Commission on
or prior to 60 days after the Issue Date, (ii) the Exchange Offer Registration
Statement or the Shelf Registration Statement, as the case may be, is not
declared effective within 180 days after the Issue Date, (iii) the Registered
Exchange Offer is not consummated on or prior to 210 days after the Issue Date,
or (iv) the Shelf Registration Statement is filed and declared effective within
180 days after the Issue Date but shall thereafter cease to be effective (at any
time that the Company is obligated to maintain the effectiveness thereof)
without being succeeded within 45 days by an additional Registration Statement
filed and declared effective (each such event referred to in clauses (i) through
(iv), a "Registration Default"), the Company shall pay liquidated damages to
each holder of Transfer Restricted Securities, during the period of such
Registration Default, in an amount equal to $0.192 per week per $1,000 of
principal amount of the Securities constituting Transfer Restricted Securities
held by such holder until the applicable Registration Statement is filed or
declared effective, the Registered Exchange Offer is consummated or the Shelf
Registration Statement again becomes effective, as the case may be.  All accrued
liquidated damages shall be paid to holders in the same manner as interest
payments on the Securities on semi-annual payment dates which correspond to
interest payment dates for the Securities.  Following the cure of all
Registration Defaults, the accrual of liquidated damages shall cease.  The
Trustee shall have no responsibility with respect to the determination of the
amount of any such liquidated damages.  For purposes of the foregoing, "Transfer
Restricted Securities" means (i) each Initial Security until the date on which
such Initial Security has been exchanged for a freely transferable Exchange
Security in the Registered Exchange Offer, (ii) each Initial Security or Private
Exchange Security until the date on which such Initial Security or Private
Exchange Security has been effectively registered under the Securities Act and
disposed of in accordance with a Shelf Registration Statement or (iii) each
Initial Security or Private Exchange Security until the date on which such
Initial Security or Private Exchange Security is distributed to the public
pursuant to Rule 144 under the Securities Act or is saleable pursuant to Rule
144(k) under the Securities Act.

2.  Method of Payment
    -----------------
<PAGE>

                                                                               5

          The Company shall pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the January 1 or July 1 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 shall pay principal, premium,
liquidated damages 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, liquidated damages and interest) shall 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
certificated 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, Bankers Trust Company, a New York banking corporation (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 July
14, 2000, (the "Indenture"), among the Company, the Subsidiary Guarantor 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. (S)(S) 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 terms and
provisions of the Indenture, and Securityholders are referred to the Indenture
and the TIA for a statement of such terms and provisions.

          The Securities are senior subordinated unsecured obligations of the
Company limited to $450,000,000 aggregate principal amount at any one time
outstanding (subject to Sections 2.01 and 2.08 of the Indenture).  This Security
is one of the Initial Securities referred to in the Indenture.  The Securities
include the Initial Securities and any Exchange Securities and Private Exchange
Securities issued in exchange for Initial Securities.  The Initial Securities,
the Exchange Securities and the Private Exchange Securities are treated as a
single class of securities under 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 Indebtedness, enter into consensual
restrictions upon the payment of certain dividends and distributions by
Restricted Subsidiaries, enter into or permit certain transactions with
Affiliates Asset Dispositions.  The Indenture also imposes limitations on the
ability of the Company to consolidate or merge with or into any other Person or
convey, transfer or lease all or substantially all of the property of the
Company.

          To guarantee 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 , by acceleration or otherwise,
<PAGE>

                                                                               6

according to the terms of the Securities and the Indenture, the Subsidiary
Guarantors jointly and severally, unconditionally guarantee the Guaranteed
Obligations on a senior subordinated basis pursuant to the terms of the
Indenture.

5.  Optional Redemption
    -------------------

          Except as set forth in the following paragraph, the Securities will
not be redeemable at the option of the Company prior to July 15, 2005.
Thereafter, the Securities will be redeemable at the option of the Company, in
whole or in part, on not less than 30 nor more than 60 days' prior notice, at
the following redemption prices (expressed as 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, if
any, due on the relevant interest payment date), if redeemed during the 12-month
period commencing on July 15 of the years set forth below:

                 ----------------------------------------------------
                 2005                                      105.313 %
                 2006                                      103.542 %
                 2007                                      101.771 %
                 2008 and thereafter                       100.000 %

          In addition, at any time and from time to time prior to July 15, 2003,
the Company  may redeem up to a maximum of 35% of the original aggregate
principal amount of the Securities with the proceeds of one or more Equity
Offerings (1) by the Company or (2) by Holdings to the extent that the proceeds
thereof are contributed to the Company, at a redemption price equal to 110.625%
of the principal amount on the redemption date; provided, however, that, after
                                                --------  -------
giving effect to any such redemption at least 65% of the original aggregate
principal amount of the Securities remains outstanding. In addition, any such
redemption shall be made within 180 days of such Equity Offering upon not less
than 30 nor more than 60 days' notice mailed to each holder of Securities being
redeemed and otherwise in accordance with the procedures set forth in the
Indenture.

          At any time on or prior to July 15, 2005, the Securities may be
redeemed as a whole but not in part at the option of the Company upon the
occurrence of a Change of Control, upon not less than 30 or more than 60 days'
prior notice (but in no event may any such redemption occur more than 90 days
after the occurrence of such Change of Control) mailed by first-class mail to
each Holder's registered address, at a redemption price equal to 100% of the
principal amount thereof plus the Applicable Premium as of, and accrued but
unpaid interest, if any, to, the redemption date, subject to the right of
Holders on the relevant record date to receive interest due on the relevant
interest payment date.

          "Applicable Premium" means with respect to a Security at any
redemption date, the greater of (i) 1.0% of the principal amount of such
Security or (ii) the excess of (A) the present value of (1) the redemption price
of such Security at July 15, 2005 (such redemption price being set forth in the
table above) plus (2) all required interest payments due on such Security
through July 15, 2005, computed using a discount rate equal to the Treasury Rate
plus 50 basis points, over (B) the then-outstanding principal amount of such
Security.

          "Treasury Rate" means the yield to maturity at the time of computation
of United States Treasury securities with a constant maturity (as compiled and
published in the most recent Federal Reserve Statistical Release H. 15(519)
which has become publicly available at least two Business Days prior to the
redemption date (or, if such Statistical Release is no longer published,
<PAGE>

                                                                               7

any publicly available source or similar market data) most nearly equal to the
period from the redemption date to July 15, 2005; provided, however, that if the
                                                  --------  -------
period from the redemption date to July 15, 2005 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall be obtained by linear interpolation
(calculated to the nearest one-twelfth of a year) from the weekly average yields
of United States Treasury securities for which such yields are given, except
that if the period from the redemption date to July 15, 2005 is less than one
year, the weekly average yield on actually traded United States Treasury
securities adjusted to a constant maturity of one year shall be used.

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 of principal amount may be redeemed in part but
only in whole multiples of $1,000 of principal amount.  If money sufficient to
pay the redemption price of and accrued and unpaid interest and liquidated
damages, if any, 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, each Holder of Securities will have the
right, subject to certain conditions specified in the Indenture, to require the
Company to repurchase all or any part of such holder's Securities at a purchase
price in cash equal to 101% of the principal amount on the Purchase Date, 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), as provided in, and subject to the terms of,
the Indenture.

9.  Subordination
    -------------

          The Securities are subordinated to Senior Indebtedness, as defined in
the Indenture.  To the extent provided in the Indenture, Senior Indebtedness
must be paid before the Securities may be paid.  The Company and each Subsidiary
Guarantor agrees, and each Securityholder by  accepting a Security agrees, to
the subordination provisions contained in the Indenture and authorizes the
Trustee to give it effect and appoints the Trustee as attorney-in-fact for such
purpose.

10. 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 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 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.

11.  Persons Deemed Owners
     ---------------------

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

12.  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.

13.  Discharge and Defeasance
     ------------------------

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

14.  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 5 of the
Indenture; (iii) to provide for uncertificated Securities in addition to or in
place of certificated Securities (provided 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);  (iv) to add Subsidiary Guarantees with respect to
the Securities; (v) to secure the Securities; (vi) to add additional covenants
or to surrender rights and powers conferred on the Company; (vii) to comply with
the requirements of the Commission in order to effect or maintain the
qualification of the Indenture under the TIA;  (viii) to make any change that
does not adversely affect the rights of any Securityholder; (ix) to make any
change in the subordination provisions of the Indenture that would limit or
terminate the benefits available to any holder of Senior Indebtedness of the
Company (or any representative thereof) under such subordination provisions; or
(x) to provide for the issuance of the Exchange Securities or Private Exchange
Securities.

15.  Defaults and Remedies
     ---------------------

          If an Event of Default occurs (other than an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of the Company)
and is continuing, the Trustee or the Holders of at least 25% in principal
amount of the outstanding Securities may declare the principal of and accrued
but unpaid interest on all the Securities to be due and payable.  If an Event of
Default relating to certain events of bankruptcy, insolvency or reorganization
of the Company occurs, the principal of and interest on all the Securities shall
become immediately due and payable without any declaration or other act on the
part of the Trustee or any Holders.  Under certain circumstances, the Holders of
a majority in principal amount of the outstanding Securities may rescind any
such acceleration with respect to the Securities and its consequences.
<PAGE>

                                                                               9

          If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture
at the request or direction of any of the Holders unless such Holders have
offered to the Trustee reasonable indemnity or security against any loss,
liability or expense.  Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Holder may pursue any
remedy with respect to the Indenture or the Securities unless (i) such Holder
has previously given the Trustee notice that an Event of Default is continuing,
(ii) Holders of at least 25% in principal amount of the outstanding Securities
have requested the Trustee in writing to pursue the remedy, (iii) such Holders
have offered the Trustee reasonable security or indemnity against any loss,
liability or expense, (iv) the Trustee has not complied with such request within
60 days after the receipt of the request and the offer of security or indemnity
and (v) the Holders of a majority in principal amount of the outstanding
Securities have not given the Trustee a direction inconsistent with such request
within such 60-day period.  Subject to certain restrictions, the Holders of a
majority in principal amount of the outstanding Securities are given the right
to 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.  The Trustee, however, may refuse to follow any direction that
conflicts with law or the Indenture or that the Trustee determines is unduly
prejudicial to the rights of any other Holder or that would involve the Trustee
in personal liability.  Prior to taking any action under the Indenture, the
Trustee shall be entitled to indemnification satisfactory to it in its sole
discretion against all losses and expenses caused by taking or not taking such
action.

16.  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.

17.  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 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.

18.  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.

19.  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).

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

          THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

21.  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.

22.  Holders' Compliance with Registration Agreement.
     ------------------------------------------------

          Each Holder of a Security, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Agreement, including, without
limitation, the obligations of the Holders with respect to a registration and
the indemnification of the Company to the extent provided therein.

          The Company will furnish to any Holder of Securities upon written
request and without charge to the Holder a copy of the Indenture which has in it
the text of this Security.

                  [FORM OF REVERSE SIDE OF EXCHANGE SECURITY]

                   10 5/8% Senior Subordinated Note due 2010

1.  Interest.
    --------

          TeleCorp PCS, 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 shall pay interest
semiannually on January 15 or July 15 of each year.  Interest on the Securities
shall accrue from the most recent date to which interest has been paid or, if no
interest has been paid or duly provided for, from July 14, 2000 until the
principal hereof is due.  Interest shall be computed on the basis of a 360-day
year of twelve 30-day months.  The Company shall pay cash 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 same rate to the extent
lawful.

2.  Method of Payment
    -----------------

          The Company shall pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the January 1 or July 1 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 shall pay principal, premium 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) shall 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 certificated 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, Bankers Trust Company, a New York banking corporation (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 July
14, 2000 (the "Indenture"), among the Company, the Subsidiary Guarantor 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. (S)(S) 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 terms and
<PAGE>

                                                                               5

provisions of the Indenture, and Securityholders are referred to the Indenture
and the TIA for a statement of such terms and provisions.

          The Securities are senior subordinated unsecured obligations of the
Company limited to $450,000,000 principal amount at any one time outstanding
(subject to Sections 2.01 and 2.08 of the Indenture).  This Security is one of
the Initial Securities referred to in the Indenture.  The Securities include the
Original Securities and any Exchange Securities and Private Exchange Securities
issued in exchange for the Initial Securities pursuant to the Indenture.  The
Initial Securities, the Exchange Securities and the Private Exchange Securities
are treated as a single class of securities under 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 Indebtedness,
enter into consensual restrictions upon the payment of certain dividends and
distributions by Restricted Subsidiaries, enter into or permit certain
transactions with Affiliates, and make Asset Dispositions.  The Indenture also
imposes limitations on the ability of the Company to consolidate or merge with
or into any other Person or convey, transfer or lease all or substantially all
of the property of the Company.

          To guarantee the due and punctual payment of the principal and
interest, if any, 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 , by acceleration or otherwise, according to the terms of the
Securities and the Indenture, the Subsidiary Guarantors have, jointly and
severally, unconditionally guaranteed the Guaranteed Obligations on a senior
subordinated basis pursuant to the terms of the Indenture.

5.  Optional Redemption
    -------------------

          Except as set forth in the following paragraph, the Securities will
not be  redeemable at the option of the Company prior to July 15, 2005.
Thereafter,  the Securities will be redeemable at the option of the Company, in
whole or in part, on not less than 30 nor more than 60 days' prior notice, at
the following redemption prices (expressed as 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,
if any, due on the relevant interest payment date), if redeemed during the 12-
month period commencing on July 15 of the years set forth below:

                                                                 Redemption
     Year                                                           Price
     -----------------------------------------------------------------------

     2005                                                           105.313%
     2006                                                           103.542%
     2007                                                           101.771%
     2008 and thereafter                                            100.000%

          In addition, at any time and from time to time prior to July 15, 2003,
the Company may redeem up to a maximum of 35% of the original aggregate
principal amount of the Securities with the proceeds of one or more Equity
Offerings (1) by the Company or (2) by Holdings to the extent that the proceeds
thereof are contributed to the Company, at a redemption price equal to 110.625%
of the principal amount on the redemption date; provided, however, that, after
                                                --------  -------
giving effect to any such redemption at least 65% of the original aggregate
principal amount of the Securities remains outstanding. In addition, any such
redemption shall be made within 180 days of such Equity Offering upon not less
than 30 nor more than 60 days' notice mailed to each holder of Securities being
redeemed and otherwise in accordance with the procedures set forth in the
Indenture.
<PAGE>

                                                                               6

          At any time on or prior to July 15, 2005, the Securities may be
redeemed as a whole but not in part at the option of the Company upon the
occurrence of a Change of Control, upon not less than 30 or more than 60 days'
prior notice (but in no event may any such redemption occur more than 90 days
after the occurrence of such Change of Control) mailed by first-class mail to
each Holder's registered address, at a redemption price equal to 100% of the
principal amount thereof plus the Applicable Premium as of, and accrued but
unpaid interest, if any, to, the redemption date, subject to the right of
Holders on the relevant record date to receive interest due on the relevant
interest payment date.

          "Applicable Premium" means with respect to a Security at any
redemption date, the greater of (i) 1.0% of the principal amount of such
Security or (ii) the excess of (A) the present value of (1) the redemption price
of such Security at July 15, 2005 (such redemption price being set forth in the
table above) plus (2) all required interest payments due on such Security
through July 15, 2005, computed using a discount rate equal to the Treasury Rate
plus 50 basis points, over (B) the then-outstanding principal amount of such
Security.

          "Treasury Rate" means the yield to maturity at the time of computation
of United States Treasury securities with a constant maturity (as compiled and
published in the most recent Federal Reserve Statistical Release H. 15(519)
which has become publicly available at least two Business Days prior to the
redemption date (or, if such Statistical Release is no longer published, any
publicly available source or similar market data) most nearly equal to the
period from the redemption date to July 15, 2005; provided, however, that if the
                                                  --------  -------
period from the redemption date to July 15, 2005 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall be obtained by linear interpolation
(calculated to the nearest one-twelfth of a year) from the weekly average yields
of United States Treasury securities for which such yields are given, except
that if the period from the redemption date to July 15, 2005 is less than one
year, the weekly average yield on actually traded United States Treasury
securities adjusted to a constant maturity of one year shall be used.

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 of principal amount may be redeemed in part but
only in whole multiples of $1,000 of principal amount.  If money sufficient to
pay the redemption price of and accrued and unpaid interest and liquidated
damages, if any, 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.

                                                                               7

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

          Upon a Change of Control, each Holder of Securities will have the
right, subject to certain conditions specified in the Indenture, to require the
Company to repurchase all or any part of such holder's Securities at a purchase
price in cash equal to 101% of the principal amount on the Purchase Date, 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), as provided in, and subject to the terms of,
the Indenture.

9.  Subordination
    -------------

          The Securities are subordinated to Senior Indebtedness, as defined in
the Indenture.  To the extent provided in the Indenture, Senior Indebtedness
must be paid before the Securities may be paid.  The Company and each Subsidiary
Guarantor agrees, and each Securityholder by  accepting a Security agrees, to
the subordination provisions contained in the Indenture and authorizes the
Trustee to give it effect and appoints the Trustee as attorney-in-fact for such
purpose.

10.  Denominations; Transfer; Exchange
     ---------------------------------

          The Securities are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000 of principal amount .  A Holder may
transfer or exchange Securities in accordance with the Indenture.  Upon any
transfer or exchange, the 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 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.

11.  Persons Deemed Owners
     ---------------------

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

12.  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.

13.  Discharge and Defeasance
     ------------------------

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

14.  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
<PAGE>

                                                                               8

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 5 of the
Indenture; (iii) to provide for uncertificated Securities in addition to or in
place of certificated Securities, (provided 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); (iv) to add Subsidiary Guarantees with respect to the
Securities; (v) to secure the Securities; (vi) to add additional covenants or to
surrender rights and powers conferred on the Company; (vii) to comply with the
requirements of the Commission in order to effect or maintain the qualification
of the Indenture under the TIA; (viii) to make any change that does not
adversely affect the rights of any Securityholder; (ix) to make any change in
the subordination provisions of the Indenture that would limit or terminate the
benefits available to any holder of Senior Indebtedness of the Company (or any
representative thereof) under such subordination provisions; or (x) to provide
for the issuance of the Exchange Securities or Private Exchange Securities.

15.  Defaults and Remedies
     ---------------------

          If an Event of Default occurs (other than an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of the Company)
and is continuing, the Trustee or the Holders of at least 25% in principal
amount of the outstanding Securities may declare the principal of and accrued
but unpaid interest on all the Securities to be due and payable.  If an Event of
Default relating to certain events of bankruptcy, insolvency or reorganization
of the Company occurs, the principal of and interest on all the Securities shall
become immediately due and payable without any declaration or other act on the
part of the Trustee or any Holders.  Under certain circumstances, the Holders of
a majority in principal amount of the outstanding Securities may rescind any
such acceleration with respect to the Securities and its consequences.

          If an Event of Default occurs and is continuing, the Trustee shall be
under no obligation to exercise any of the rights or powers under the Indenture
at the request or direction of any of the Holders unless such Holders have
offered to the Trustee reasonable indemnity or security against any loss,
liability or expense.  Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Holder may pursue any
remedy with respect to the Indenture or the Securities unless (i) such Holder
has previously given the Trustee notice that an Event of Default is continuing,
(ii) Holders of at least 25% in principal amount of the outstanding Securities
have requested the Trustee in writing to pursue the remedy, (iii) such Holders
have offered the Trustee reasonable security or indemnity against any loss,
liability or expense, (iv) the Trustee has not complied with such request within
60 days after the receipt of the request and the offer of security or indemnity
and (v) the Holders of a majority in principal amount of the outstanding
Securities have not given the Trustee a direction inconsistent with such request
within such 60-day period.  Subject to certain restrictions, the Holders of a
majority in principal amount of the outstanding Securities are given the right
to 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.  The Trustee, however, may refuse to follow any direction that
conflicts with law or the Indenture or that the Trustee determines is unduly
prejudicial to the rights of any other Holder or that would involve the Trustee
in personal liability.  Prior to taking any action under the Indenture, the
Trustee shall be entitled to indemnification satisfactory to it in its sole
discretion against all losses and expenses caused by taking or not taking such
action.

                                                                               9

16.  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.

17.  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 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.

18.  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.

19.  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).

20.  Governing Law
     -------------

          THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

21.  CUSIP Numbers
     -------------

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

          The Company will furnish to any Holder of Securities upon written
request and without charge to the Holder a copy of the Indenture which has in it
the text of this Security.

Ladies and Gentlemen:

     This certificate is delivered to request a transfer of $    principal
amount of the 105/8% Senior Subordinated Notes due 2010 (the "Securities") of
TeleCorp PCS, Inc. (the "TeleCorp").

     Upon transfer, the Notes would be registered in the name of the new
beneficial owner as follows:

Name:________________________

Address:_____________________

Taxpayer ID Number:__________

     The undersigned represents and warrants to you that:

     1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")), purchasing for our own account or for the account of such an
institutional "accredited investor" at least $250,000 principal amount of the
Securities, and we are acquiring the Securities not with a view to, or for offer
or sale in connection with, any distribution in violation of the Securities Act.
We have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Securities,
and we invest in or purchase securities similar to the Securities in the normal
course of our business.  We, and any accounts for which we are acting, are each
able to bear the economic risk of our or its investment.

     2. We understand that the Securities have not been registered under the
Securities Act and, unless so registered, may not be sold except as permitted in
the following sentence.  We agree on our own behalf and on behalf of any
investor account for which we are purchasing the Securities to offer, sell or
otherwise transfer such Securities prior to the date that is two years after the
later of the date of original issue and the last date on which TeleCorp or any
affiliate of TeleCorp was the owner of such Securities (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (a) to TeleCorp, (b)
pursuant to a registration statement that has been declared effective under the
Securities Act, (c) in a transaction complying with the requirements of Rule
144A under the Securities Act ("Rule 144A"), to a person we reasonably believe
is a qualified institutional buyer under Rule 144A (a "QIB") that is purchasing
for its own account or for the account of a QIB and to whom notice is given that
the transfer is being made in reliance on Rule 144A, (d) in an offshore
transaction within the meaning of, and in compliance with, Regulation S under
the Securities Act, (e) to an institutional "accredited investor" within the
meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is
purchasing for its own account or for the account of such an institutional
"accredited investor", in each case in a

minimum principal amount of Securities of $250,000, or (f) pursuant to any other
available exemption from the registration requirements of the Securities Act,
subject in each of the foregoing cases to any requirement of law that the
disposition of our property or the property of such investor account or accounts
be at all times within our or their control and in compliance with any
applicable state securities laws. The foregoing restrictions on resale will not
apply subsequent to the Resale Restriction Termination Date. If any resale or
other transfer of the Securities is proposed to be made pursuant to clause (e)
above prior to the Resale Restriction Termination Date, the transferor shall
deliver a letter from the transferee substantially in the form of this letter to
TeleCorp and the Trustee, which shall provide, among other things, that the
transferee is an institutional "accredited investor" within the meaning of Rule
501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring
such Securities for investment purposes and not for distribution in violation of
the Securities Act. Each purchaser acknowledges that TeleCorp and the Trustee
reserve the right prior to the offer, sale or other transfer prior to the Resale
Restriction Termination Date of the Securities pursuant to clause (d), (e) or
(f) above to require the delivery of an opinion of counsel, certifications or
other information satisfactory to TeleCorp and the Trustee.

Attn:  Thomas H. Sullivan, Esq.

Ladies and Gentlemen:

          Lucent Technologies Inc. ("Lucent")  is pleased to provide its
commitment to purchase from TeleCorp-Tritel Holding Company (the name of which
is intended to be changed to TeleCorp PCS, Inc.) (the "Company") Senior
                                                       -------
Subordinated Discount Notes Due 2010 (the "Notes") in an aggregate principal
                                           -----
amount which will yield to the Company gross proceeds of $350,000,000.  The
Notes will be sold pursuant to the Securities Purchase Agreement between Lucent
and the Company (the "Securities Purchase Agreement") and will be issued
                      -----------------------------
pursuant to the Indenture of the Company (the "Indenture") each in the form
                                               ---------
attached hereto, with such modifications as Lucent and the Company may mutually
agree upon.

          The parties will prepare, execute and deliver mutually acceptable
supporting and ancillary documentation to the Indenture and Securities Purchase
Agreement, including, without limitation, an exchange and registration rights
agreement and the Notes, each modeled upon documents prepared in connection with
the Company's 10 5/8% Senior Subordinated Notes due 2010.

          This Commitment Letter is intended as an outline only and does not
summarize all the terms, conditions, representations, warranties, defaults and
other provisions that are contained in the Indenture and the Securities Purchase
Agreement and that will be contained in the ancillary documentation.  Lucent's
commitment is subject to the absence of any material

adverse change in the business, condition (financial or otherwise), operations,
performance, properties or prospects of TeleCorp-Tritel Holding Company,
TeleCorp PCS, Inc. and each of their respective subsidiaries taken as a whole
since July 10, 2000.

          Lucent intends to market the Notes to underwriters and financial
institutions ("Prospective Purchasers") identified by Lucent in consultation
               ----------------------
with the Company.  The Company agrees to actively assist in the preparation of
an Offering Memorandum and other marketing materials to be used in connection
with the marketing and sale of the Notes and the hosting, with Lucent, of one or
more meetings of underwriters and Prospective Purchasers.

          Lucent will manage all aspects of the sale of the Notes to the
Prospective Purchasers, including decisions as to the selection of institutions
to be approached, when their commitments will be accepted, which institutions
will participate and the allocations of the commitments among the Prospective
Purchasers.  To assist Lucent in our efforts, the Company agrees promptly to
prepare and provide to Lucent all information with respect to the Company and
the transactions contemplated hereby, including all financial information and
projections (the "Projections"), as Lucent may reasonably request in connection
                  -----------
with the marketing and sale of the Notes to the Prospective Purchasers.  The
Company hereby represents and covenants that (a) all information other than the
Projections (the "Information") that has been or will be made available to
                  -----------
Lucent by the Company or any of the Company's representatives or advisors does
not and will not, when finished, contain any untrue statement of a material fact
or omit to state a material fact necessary in order to make the statements
contained therein not materially misleading in light of the circumstances under
which such statements are made and (b) the Projections that have been or will be
made available to Lucent by the Company or any of the Company's representatives
or advisors have been or will be prepared in good faith based upon the
reasonable assumptions stated therein.  In marketing the sale of the Notes to
underwriters and Prospective Purchasers, Lucent will use and rely on the
Information and Projections without independent verification thereof.

          By acceptance of this Commitment Letter, the Company agrees (a) to
indemnify and hold harmless Lucent, its affiliates and its officers, directors,
employees, advisors, and agents (each, an "indemnified person") from and against
any and all losses, claims, damages and liabilities to which any such
indemnified person may become subject arising out of or in connection with this
Commitment Letter and the transactions contemplated thereby, the Notes, the use
of proceeds thereof, any related transaction (excluding for this purpose the
transactions contemplated by the Procurement Contract (as defined in the
attached form of Securities Purchase Agreement)) or any claim, litigation,
investigation or proceeding relating to any of the foregoing, regardless of
whether any indemnified person is a party thereto, and to reimburse each
indemnified person upon demand for any legal or other expenses incurred in
connection with investigating or defending any of the foregoing; provided that
                                                                 --------
the foregoing indemnity will not, as to any indemnified person, apply to losses,
claims, damages, liabilities or related expenses to the extent they arise from
the willful misconduct or gross negligence of such indemnified person, and (b)
to reimburse Lucent and its affiliates on demand for all reasonable out-of-
pocket expenses (including due diligence expenses, syndication expenses,
consultant's fees and expenses, travel expenses, and reasonable fees, charges
and disbursements of counsel) incurred in connection with the Notes.  No
indemnified person shall be liable for any indirect or consequential damages in
connection with its activities related to the Notes.  The provisions of

one agreement.  Delivery of an executed signature page of this Commitment Letter
by facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof.  This Commitment Letter shall be governed by, and construed
in accordance with, the laws of the State of New York.  The Company and Lucent
each hereby irrevocably waive all right to trial by jury in any action,
proceeding or counterclaim (whether based on contract or otherwise) arising out
of or relating to this Commitment Letter, the transactions contemplated hereby
or the actions of Lucent in the negotiation, performance or enforcement hereof.

          Please evidence your acceptance of the provisions of this Commitment
Letter, and the other matters referred to above by signing the enclosed copies

available after the earlier to occur of June 30, 2002 and the first anniversary
of the consummation of the merger of Tritel and TeleCorp PCS, Inc., if
definitive documentation shall not have been executed by such date.
