     INDENTURE dated as of April 30, 2004 among iPCS Escrow Company, a Delaware
corporation, iPCS, Inc., each of the Guarantors and U.S. Bank National
Association, a national banking association, as trustee.

     The issuance of the Initial Notes pursuant to this Indenture is part of the
reorganization of the ownership and capital structure of iPCS, Inc., a Delaware
corporation. As part of the consummation of the Reorganization, iPCS Escrow
Company will merge with and into iPCS, Inc. after which iPCS, Inc. will be the
surviving entity (the "Merger"). Upon consummation of the Merger, iPCS, Inc.
will assume all of the obligations of iPCS Escrow Company under this Indenture.
The word "Company" as used herein refers only to iPCS Escrow Company before the
Merger and to iPCS, Inc. after the Merger. No part of the Reorganization will be
deemed to violate Articles 4, 5 and 6 hereof.

     On the date hereof, iPCS Escrow Company will deposit the gross proceeds
from the offering of the Initial Securities, and iPCS, Inc. will deposit such
additional amounts equal to accrued and unpaid interest on the Initial
Securities up to but not including August 31, 2004 in an escrow account (the
"Escrow Account") pursuant to an Escrow Agreement to be dated the date hereof
(the "Escrow Agreement") between iPCS Escrow Company and U.S. Bank National
Association, as Escrow Agent (the "Escrow Agent"). The funds in the Escrow
Account will be used on or before August 28, 2004 to consummate the
Reorganization on the terms described in the Offering Circular or, in the event
of a Special Mandatory Redemption, released to finance the redemption price of
the Initial Securities in connection therewith.

     The Company and the Trustee agree as follows for the benefit of each other
and for the equal and ratable benefit of the Holders (as defined) of the 11 1/2%
Senior Notes due 2012 (the "NOTES"):

be in denominations of $1,000 and integral multiples thereof.

     The terms and provisions contained in the Notes will constitute, and are
hereby expressly made, a part of this Indenture and the Company and the Trustee,
by their execution and delivery of this Indenture, expressly agree to such terms
and provisions and to be bound thereby. However, to the extent any provision of
any Note conflicts with the express provisions of this Indenture, the provisions
of this Indenture shall govern and be controlling.

     (b)  GLOBAL NOTES. Notes issued in global form will be substantially in the
form of Exhibit A hereto (including the Global Note Legend thereon and the
"Schedule of Exchanges of Interests in the Global Note" attached thereto). Notes
issued in definitive form will be substantially in the form of Exhibit A hereto
(but without the Global Note Legend thereon and without the "Schedule of
Exchanges of Interests in the Global Note" attached thereto). Each Global Note
will represent such of the outstanding Notes as will be specified therein and
each shall provide that it represents the aggregate principal amount of
outstanding Notes from time to time endorsed thereon and that the aggregate
principal amount of outstanding Notes represented thereby may from time to time
be reduced or increased, as appropriate, to reflect exchanges and redemptions.
Any endorsement of a Global Note to reflect the amount of any increase or

                                       22

decrease in the aggregate principal amount of outstanding Notes represented
thereby will be made by the Trustee or the Custodian, at the direction of the
Trustee, in accordance with instructions given by the Holder thereof as required
by Section 2.06 hereof.

     (c)  EUROCLEAR AND CLEARSTREAM PROCEDURES APPLICABLE. The provisions of the
"Operating Procedures of the Euroclear System" and "Terms and Conditions
Governing Use of Euroclear" and the "General Terms and Conditions of Clearstream
Banking" and "Customer Handbook" of Clearstream will be applicable to transfers
of beneficial interests in the Regulation S Global Note that are held by
Participants through Euroclear or Clearstream.

Section 2.02   EXECUTION AND AUTHENTICATION.

     At least one Officer must sign the Notes for the Company by manual or
facsimile signature.

     If an Officer whose signature is on a Note no longer holds that office at
the time a Note is authenticated, the Note will nevertheless be valid.

     A Note will not be valid until authenticated by the manual signature of the
Trustee. The signature will be conclusive evidence that the Note has been
authenticated under this Indenture.

     The Trustee will, upon receipt of a written order of the Company signed by
at least two Officers (an "AUTHENTICATION ORDER"), authenticate Notes for
original issue that may be validly issued under this Indenture, including any
Additional Notes. The aggregate principal amount of Notes outstanding at any
time may not exceed the aggregate principal amount of Notes authorized for
issuance by the Company pursuant to one or more Authentication Orders, except as
provided in Section 2.07 hereof.

     The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Notes. An authenticating agent may authenticate Notes whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with Holders or an Affiliate of the Company.

Section 2.03   REGISTRAR AND PAYING AGENT.

     The Company will maintain an office or agency where Notes may be presented
for registration of transfer or for exchange ("REGISTRAR") and an office or
agency where Notes may be presented for payment ("PAYING AGENT"). The Registrar
will keep a register of the Notes and of their transfer and exchange. The
Company may appoint one or more co-registrars and one or more additional paying
agents. The term "Registrar" includes any co-registrar and the term "Paying
Agent" includes any additional paying agent. The Company may change any Paying
Agent or Registrar without notice to any Holder. The Company will notify the
Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any of
its Subsidiaries may act as Paying Agent or Registrar.

                                       23

     The Company initially appoints The Depository Trust Company ("DTC") to act
as Depositary with respect to the Global Notes.

     The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Custodian with respect to the Global Notes.

Section 2.04   PAYING AGENT TO HOLD MONEY IN TRUST.

     The Company will require each Paying Agent other than the Trustee to agree
in writing that the Paying Agent will hold in trust for the benefit of Holders
or the Trustee all money held by the Paying Agent for the payment of principal,
premium or Liquidated Damages, if any, or interest on the Notes, and will notify
the Trustee of any default by the Company in making any such payment. While any
such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee. The Company at any time may require a Paying Agent to
pay all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary) will have no further
liability for the money. If the Company or a Subsidiary acts as Paying Agent, it
will segregate and hold in a separate trust fund for the benefit of the Holders
all money held by it as Paying Agent. Upon any bankruptcy or reorganization
proceedings relating to the Company, the Trustee will serve as Paying Agent for
the Notes.

Section 2.05   HOLDER LISTS.

     The Trustee will preserve in as current a form as is reasonably practicable
the most recent list available to it of the names and addresses of all Holders
and shall otherwise comply with TIA Section 312(a). If the Trustee is not the
Registrar, the Company will furnish to the Trustee at least seven Business Days
before each interest payment date and at such other times as the Trustee may
request in writing, a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of the Holders of Notes and the
Company shall otherwise comply with TIA Section 312(a).

Section 2.06   TRANSFER AND EXCHANGE.

     (a)  TRANSFER AND EXCHANGE OF GLOBAL NOTES. A Global Note may not be
transferred except as a whole by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Notes will be exchanged by
the Company for Definitive Notes if:

          (1)  the Company delivers to the Trustee notice from the Depositary
     that it is unwilling or unable to continue to act as Depositary or that it
     is no longer a clearing agency registered under the Exchange Act and, in
     either case, a successor Depositary is not appointed by the Company within
     120 days after the date of such notice from the Depositary;

          (2)  the Company in its sole discretion determines that the Global
     Notes (in whole but not in part) should be exchanged for Definitive Notes
     and delivers a written notice to such effect to the Trustee; or

                                       24
<Page>

          (3)  there has occurred and is continuing a Default or Event of
     Default with respect to the Notes.

     Upon the occurrence of either of the preceding events in (1) or (2) above,
Definitive Notes shall be issued in such names as the Depositary shall instruct
the Trustee. Global Notes also may be exchanged or replaced, in whole or in
part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and
delivered in exchange for, or in lieu of, a Global Note or any portion thereof,
pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be
authenticated and delivered in the form of, and shall be, a Global Note. A
Global Note may not be exchanged for another Note other than as provided in this
Section 2.06(a), however, beneficial interests in a Global Note may be
transferred and exchanged as provided in Section 2.06(b), (c) or (f) hereof.

     (b)  TRANSFER AND EXCHANGE OF BENEFICIAL INTERESTS IN THE GLOBAL NOTES. The
transfer and exchange of beneficial interests in the Global Notes will be
effected through the Depositary, in accordance with the provisions of this
Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Notes will be subject to restrictions on transfer comparable to those set
forth herein to the extent required by the Securities Act. Transfers of
beneficial interests in the Global Notes also will require compliance with
either subparagraph (1) or (2) below, as applicable, as well as one or more of
the other following subparagraphs, as applicable:

          (1)  TRANSFER OF BENEFICIAL INTERESTS IN THE SAME GLOBAL NOTE.

     Persons who take delivery thereof in the form of a beneficial interest in
     the same Restricted Global Note in accordance with the transfer
     restrictions set forth in the Private Placement Legend; PROVIDED, HOWEVER,
     that prior to the expiration of the Restricted Period, transfers of
     beneficial interests in the Regulation S Global Note may not be made to a
     U.S. Person or for the account or benefit of a U.S. Person (other than an
     Initial Purchaser). Beneficial interests in any Unrestricted Global Note
     may be transferred to Persons who take delivery thereof in the form of a
     beneficial interest in an Unrestricted Global Note. No written orders or
     instructions shall be required to be delivered to the Registrar to effect
     the transfers described in this Section 2.06(b)(1).

          (2)  ALL OTHER TRANSFERS AND EXCHANGES OF BENEFICIAL INTERESTS IN

               Registrar containing information regarding the Person in whose

have been satisfied upon receipt by the Registrar of the instructions contained
in the Letter of Transmittal delivered by the Holder of such beneficial
interests in the Restricted Global Notes. Upon satisfaction of all of the
requirements for transfer or exchange of beneficial interests in Global Notes
contained in this Indenture and the Notes or otherwise applicable under the
Securities Act, the Trustee shall adjust the principal amount of the relevant
Global Note(s) pursuant to Section 2.06(h) hereof.

          (3)  TRANSFER OF BENEFICIAL INTERESTS TO ANOTHER RESTRICTED GLOBAL
     NOTE. A beneficial interest in any Restricted Global Note may be

     Restricted Definitive Note may be exchanged by the Holder thereof for an
     Unrestricted Definitive Note or transferred to a Person or Persons who take
     delivery thereof in the form of an Unrestricted Definitive Note if:

               (A)  such exchange or transfer is effected pursuant to the
          Exchange Offer in accordance with the Registration Rights Agreement
          and the Holder, in the case of an exchange, or the transferee, in the
          case of a transfer, certifies in the applicable Letter of Transmittal
          that it is not (i) a Broker-Dealer, (ii) a Person participating in the

          Registration Statement in accordance with the Registration Rights
          Agreement;

               proposes to transfer such Notes to a Person who shall take
               delivery thereof in the form of an Unrestricted Definitive Note,
               a certificate from such Holder in the form of Exhibit B hereto,
               including the certifications in item (4) thereof;

and, in each such case set forth in this subparagraph (D), if the Registrar so
requests, an Opinion of Counsel in form reasonably acceptable to the Registrar

Securities Act and that the restrictions on transfer contained

                                       33
<Page>

herein and in the Private Placement Legend are no longer required in order to
maintain compliance with the Securities Act.

          (3)  UNRESTRICTED DEFINITIVE NOTES TO UNRESTRICTED DEFINITIVE NOTES. A
     Holder of Unrestricted Definitive Notes may transfer such Notes to a Person
     who takes delivery thereof in the form of an Unrestricted Definitive Note.
     Upon receipt of a request to register such a transfer, the Registrar shall
     register the Unrestricted Definitive Notes pursuant to the instructions
     from the Holder thereof.

     (f)  EXCHANGE OFFER. Upon the occurrence of the Exchange Offer in
accordance with the Registration Rights Agreement, the Company will issue and,
upon receipt of an Authentication Order in accordance with Section 2.02 hereof,
the Trustee will authenticate:

          (1)  one or more Unrestricted Global Notes in an aggregate principal
     amount equal to the principal amount of the beneficial interests in the
     Restricted Global Notes accepted for exchange in the Exchange Offer by
     Persons that certify in the applicable Letters of Transmittal that (A) they
     are not Broker-Dealers, (B) they are not participating in a distribution of
     the Exchange Notes and (C) they are not affiliates (as defined in Rule 144)
     of the Company; and

          (2)  Unrestricted Definitive Notes in an aggregate principal amount
     equal to the principal amount of the Restricted Definitive Notes accepted
     for exchange in the Exchange Offer by Persons that certify in the
     applicable Letters of Transmittal that (A) they are not Broker-Dealers, (B)
     they are not participating in a distribution of the Exchange Notes and (C)
     they are not affiliates (as defined in Rule 144) of the Company.

authenticate and deliver to the Persons designated by the Holders of Definitive
Notes so accepted Unrestricted Definitive Notes in the appropriate principal
amount.

     (g)  LEGENDS. The following legends will appear on the face of all Global
Notes and Definitive Notes issued under this Indenture unless specifically
stated otherwise in the applicable provisions of this Indenture.

          (1)  PRIVATE PLACEMENT LEGEND.

               (A)  Except as permitted by subparagraph (B) below, each Global

EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND, IN EACH CASE, IN
ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES
OR ANY OTHER APPLICABLE JURISDICTION AND THE INDENTURE GOVERNING THE NOTES AND
(B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY
PURCHASER FROM IT OF THE NOTE EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET
FORTH IN (A) ABOVE. IF ANY RESALE OR OTHER TRANSFER OF ANY NOTE IS PROPOSED TO
BE MADE UNDER CLAUSE (A)(1)(d) ABOVE WHILE THESE TRANSFER RESTRICTIONS ARE IN
FORCE, THEN THE TRANSFEROR SHALL DELIVER A LETTER FROM THE TRANSFEREE TO THE
COMPANY AND THE TRUSTEE WHICH SHALL PROVIDE, AMONG OTHER THINGS, THAT THE
TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR AND THAT IT IS ACQUIRING THE
SECURITIES FOR INVESTMENT PURPOSES AND NOT FOR DISTRIBUTION IN VIOLATION OF THE
SECURITIES ACT."

               (B)  Notwithstanding the foregoing, any Global Note or Definitive
          Note issued pursuant to subparagraphs (b)(4), (c)(2), (c)(3), (d)(2),
          (d)(3), (e)(2), (e)(3) or (f) of this Section 2.06 (and all Notes
          issued in exchange therefor or substitution thereof) will not bear the
          Private Placement Legend.

          (2)  GLOBAL NOTE LEGEND. Each Global Note will bear a legend in
     substantially the following form:

                                       35

FORM, THIS NOTE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A
NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR

     (h)  CANCELLATION AND/OR ADJUSTMENT OF GLOBAL NOTES. At such time as all
beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note will be returned to or
retained and canceled by the Trustee in accordance with Section 2.11 hereof. At
any time prior to such cancellation, if any beneficial interest in a Global Note
is exchanged for or transferred to a Person who will take delivery thereof in
the form of a beneficial interest in another Global Note or for Definitive
Notes, the principal amount of Notes represented by such Global Note will be
reduced accordingly and an endorsement will be made on such Global Note by the
Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction; and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial interest
in another Global Note, such other Global Note will be increased accordingly and
an endorsement will be made on such Global Note by the Trustee or by the
Depositary at the direction of the Trustee to reflect such increase.

     (i)  GENERAL PROVISIONS RELATING TO TRANSFERS AND EXCHANGES.

                                       36
<Page>

          (1)  To permit registrations of transfers and exchanges, the Company
     will execute and the Trustee will authenticate Global Notes and Definitive
     Notes upon receipt of an Authentication Order in accordance with Section
     2.02 hereof or at the Registrar's request.

          (2)  No service charge will be made to a Holder of a beneficial
     interest in a Global Note or to a Holder of a Definitive Note for any
     registration of transfer or exchange, but the Company may require payment
     of a sum sufficient to cover any transfer tax or similar governmental
     charge payable in connection therewith (other than any such transfer taxes
     or similar governmental charge payable upon exchange or transfer pursuant
     to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

          (3)  The Registrar will not be required to register the transfer of or
     exchange of any Note selected for redemption in whole or in part, except
     the unredeemed portion of any Note being redeemed in part.

          (4)  All Global Notes and Definitive Notes issued upon any
     registration of transfer or exchange of Global Notes or Definitive Notes
     will be the valid obligations of the Company, evidencing the same debt, and
     entitled to the same benefits under this Indenture, as the Global Notes or
     Definitive Notes surrendered upon such registration of transfer or
     exchange.

          (5)  Neither the Registrar nor the Company will be required:

               (A)  to issue, to register the transfer of or to exchange any
          Notes during a period beginning at the opening of business 15 days
          before the day of any selection of Notes for redemption under Section
          3.02 hereof and ending at the close of business on the day of
          selection;

               (B)  to register the transfer of or to exchange any Note selected
          for redemption in whole or in part, except the unredeemed portion of
          any Note being redeemed in part; or

               (C)  to register the transfer of or to exchange a Note between a
          record date and the next succeeding interest payment date.

          (6)  Prior to due presentment for the registration of a transfer of
     any Note, the Trustee, any Agent and the Company may deem and treat the
     Person in whose name any Note is registered as the absolute owner of such
     Note for the purpose of receiving payment of principal of and interest on
     such Notes and for all other purposes, and none of the Trustee, any Agent
     or the Company shall be affected by notice to the contrary.

          (7)  The Trustee will authenticate Global Notes and Definitive Notes
     in accordance with the provisions of Section 2.02 hereof.

          (8)  All certifications, certificates and Opinions of Counsel required
     to be submitted to the Registrar pursuant to this Section 2.06 to effect a

Section 2.07   REPLACEMENT NOTES.

     If any mutilated Note is surrendered to the Trustee or the Company and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, the Company will issue and the Trustee, upon receipt of an
Authentication Order, will authenticate a replacement Note if the Trustee's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge for its expenses in replacing a Note.

     Every replacement Note is an additional obligation of the Company and will
be entitled to all of the benefits of this Indenture equally and proportionately
with all other Notes duly issued hereunder.

Section 2.08   OUTSTANDING NOTES.

     The Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those reductions in the interest in a Global Note effected by the Trustee in
accordance with the provisions hereof, and those described in this Section 2.08
as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not
cease to be outstanding because the Company or an Affiliate of the Company holds
the Note; however, Notes held by the Company or a Subsidiary of the Company
shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

     If a Note is replaced pursuant to Section 2.07 hereof, it will be deemed
outstanding only if the Trustee receives proof satisfactory to it that the
replaced Note is held by a protected purchaser within the meaning of Section
8-303 of the New York Uniform Commercial Code.

     If the principal amount of any Note is considered paid under Section 4.01
hereof, it ceases to be outstanding and interest on it ceases to accrue.

     If the Paying Agent (other than the Company, a Subsidiary or an Affiliate
of any thereof) holds, on a redemption date or maturity date, money sufficient
to pay Notes payable on that date, then on and after that date such Notes will
be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09   TREASURY NOTES.

     In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company or any Guarantor, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
Guarantor, will be considered as though not outstanding, except that for the
purposes of determining whether the Trustee will be protected in relying on any
such direction, waiver or consent, only Notes that a Responsible Officer of the
Trustee knows are so owned will be so disregarded.

                                       38

Section 2.10   TEMPORARY NOTES.

     Until certificates representing Notes are ready for delivery, the Company
may prepare and the Trustee, upon receipt of an Authentication Order, will
authenticate temporary Notes. Temporary Notes will be substantially in the form
of certificated Notes but may have variations that the Company considers
appropriate for temporary Notes and as may be reasonably acceptable to the
Trustee. Without unreasonable delay, the Company will prepare and the Trustee
will authenticate definitive Notes in exchange for temporary Notes.

     Holders of temporary Notes will be entitled to all of the benefits of this
Indenture.

Section 2.11   CANCELLATION.

     The Company at any time may deliver Notes to the Trustee for cancellation.
The Registrar and Paying Agent will forward to the Trustee any Notes surrendered
to them for registration of transfer, exchange or payment. The Trustee and no
one else will cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation and will dispose of canceled
Notes in accordance with its customary procedures (subject to the record
retention requirement of the Exchange Act). The Company may not issue new Notes
to replace Notes that it has paid or that have been delivered to the Trustee for
cancellation.

Section 2.12   DEFAULTED INTEREST.

     If the Company defaults in a payment of interest on the Notes, it will pay
the defaulted interest in any lawful manner plus, to the extent lawful, interest
payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.01 hereof. The Company will notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date
of the proposed payment. The Company will fix or cause to be fixed each such
special record date and payment date; PROVIDED that no such special record date
may be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) will mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

     If the Company elects to redeem Notes pursuant to the optional redemption
provisions of Section 3.07 hereof, it must furnish to the Trustee, at least 35
days but not more than 60 days before a redemption date (or such shorter period
as may be agreed between the Company and the Trustee), an Officers' Certificate

          (1)  the clause of this Indenture pursuant to which the redemption
     shall occur;

          (2)  the redemption date;

          (4)  the redemption price.

Section 3.02   SELECTION OF NOTES TO BE REDEEMED OR PURCHASED.

     If less than all of the Notes are to be redeemed or purchased in an offer
to purchase at any time, the Trustee will select Notes for redemption or
purchase pro rata, by lot or by such other method as the Trustee shall deem fair
and appropriate except:

          (1)  if the Notes are listed on any national securities exchange, in
     compliance with the requirements of the principal national securities
     exchange on which the Notes are listed; or

          (2)  if otherwise required by law.

     In the event of partial redemption or purchase by lot, the particular Notes
to be redeemed or purchased will be selected, unless otherwise provided herein,
not less than 30 nor more than 60 days prior to the redemption or purchase date
by the Trustee from the outstanding Notes not previously called for redemption
or purchase.

     The Trustee will promptly notify the Company in writing of the Notes
selected for redemption or purchase and, in the case of any Note selected for
partial redemption or purchase, the principal amount thereof to be redeemed or
purchased. Notes and portions of Notes selected will be in amounts of $1,000 or
whole multiples of $1,000; except that if all of the Notes of a Holder are to be
redeemed or purchased, the entire outstanding amount of Notes held by such
Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except
as provided in the preceding sentence, provisions of this Indenture that apply
to Notes called for redemption or purchase also apply to portions of Notes
called for redemption or purchase.

Section 3.03   NOTICE OF REDEMPTION.

     Subject to the provisions of Section 3.09 hereof, at least 30 days but not
more than 60 days before a redemption date, the Company will mail or cause to be
mailed, by first class mail, a notice of redemption to each Holder whose Notes
are to be redeemed at its registered address, except that redemption notices may
be mailed more than 60 days prior to a redemption date if the notice is issued
in connection with a defeasance of the Notes or a satisfaction and discharge of
this Indenture pursuant to Articles 8 or 11 hereof.

     The notice will identify the Notes to be redeemed (including the CUSIP
number) and will state:

          (1)  the redemption date;

          (2)  the redemption price;

          (3)  if any Note is being redeemed in part, the portion of the
     principal amount of such Note to be redeemed and that, after the redemption
     date upon surrender of such

                                       40
<Page>

     Note, a new Note or Notes in principal amount equal to the unredeemed
     portion will be issued upon cancellation of the original Note;

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

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

          (6)  that, unless the Company defaults in making such redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the redemption date;

          (7)  the paragraph of the Notes and/or section of this Indenture
     pursuant to which the Notes called for redemption are 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 Notes.

     At the Company's request, the Trustee will give the notice of redemption in
the Company's name and at its expense; PROVIDED, HOWEVER, that the Company has
delivered to the Trustee, at least 35 days prior to the redemption date (or such
shorter period as may be agreed between the Company and the Trustee), an
Officers' Certificate requesting that the Trustee give such notice and setting
forth the information to be stated in such notice as provided in the preceding
paragraph.

Section 3.04   EFFECT OF NOTICE OF REDEMPTION.

     Once notice of redemption is mailed in accordance with Section 3.03 hereof,
Notes called for redemption become irrevocably due and payable on the redemption
date at the redemption price. A notice of redemption may not be conditional.

Section 3.05   DEPOSIT OF REDEMPTION OR PURCHASE PRICE.

     One Business Day prior to the redemption or purchase date, the Company will
deposit with the Trustee or with the Paying Agent money sufficient to pay the
redemption or purchase price of and accrued interest and Liquidated Damages, if
any, on all Notes to be redeemed or purchased on that date. The Trustee or the
Paying Agent will promptly return to the Company any money deposited with the
Trustee or the Paying Agent by the Company in excess of the amounts necessary to
pay the redemption or purchase price of, and accrued interest and Liquidated
Damages, if any, on, all Notes to be redeemed or purchased.

     If the Company complies with the provisions of the preceding paragraph, on
and after the redemption or purchase date, interest will cease to accrue on the
Notes or the portions of Notes called for redemption or purchase. If a Note is
redeemed or purchased on or after an interest record date but on or prior to the
related interest payment date, then any accrued and unpaid interest shall be
paid to the Person in whose name such Note was registered at the close of
business on such record date. If any Note called for redemption or purchase is
not so paid upon surrender for redemption or purchase because of the failure of
the Company to comply with the preceding paragraph, interest shall be paid on
the unpaid principal, from the redemption or

                                       41

purchase date until such principal is paid, and to the extent lawful on any
interest not paid on such unpaid principal, in each case at the rate provided in
the Notes and in Section 4.01 hereof.

Section 3.06   NOTES REDEEMED OR PURCHASED IN PART.

     Upon surrender of a Note that is redeemed or purchased in part, the Company
will issue and, upon receipt of an Authentication Order, the Trustee will
authenticate for the Holder at the expense of the Company a new Note equal in
principal amount to the unredeemed or unpurchased portion of the Note
surrendered.

Section 3.09   OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

     In the event that, pursuant to Section 4.10 hereof, the Company is required
to commence an offer to all Holders to purchase Notes (an "ASSET SALE OFFER"),
it will follow the procedures specified below.

     The Asset Sale Offer shall be made to all Holders and all holders of other
Indebtedness that is PARI PASSU with the Notes containing provisions similar to
those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets. The Asset Sale Offer will remain open for
a period of at least 20 Business Days following its commencement and not more
than 30 Business Days, except to the extent that a longer period is required by
applicable law (the "OFFER PERIOD"). No later than three Business Days after the
termination of the Offer Period (the "PURCHASE DATE"), the Company will apply
all Excess Proceeds (the "OFFER AMOUNT") to the purchase of Notes and such other
PARI PASSU Indebtedness (on a PRO RATA basis, if applicable) or, if less than
the Offer Amount has been tendered, all Notes and other Indebtedness tendered in
response to the Asset Sale Offer. Payment for any Notes so purchased will be
made in the same manner as interest payments are made.

     If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest and
Liquidated Damages, if any, will be paid to the Person in whose name a Note is
registered at the close of business on such record date, and no additional
interest will be payable to Holders who tender Notes pursuant to the Asset Sale
Offer.

     Upon the commencement of an Asset Sale Offer, the Company will send, by
first class mail, a notice to the Trustee and each of the Holders, with a copy
to the Trustee. The notice will contain all instructions and materials necessary
to enable such Holders to tender Notes pursuant

                                       43

Sale Offer, will state:

          (1)  that the Asset Sale Offer is being made pursuant to this Section
     3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer
     will remain open;

          (2)  the Offer Amount, the purchase price and the Purchase Date;

          (3)  that any Note not tendered or accepted for payment will continue
     to accrue interest;

          (4)  that, unless the Company defaults in making such payment, any
     Note accepted for payment pursuant to the Asset Sale Offer will cease to
     accrue interest after the Purchase Date;

          (5)  that Holders electing to have a Note purchased pursuant to an
     Asset Sale Offer may elect to have Notes purchased in integral multiples of
     $1,000 only;

          (6)  that Holders electing to have Notes purchased pursuant to any
     Asset Sale Offer will be required to surrender the Note, with the form
     entitled "Option of Holder to Elect Purchase" attached to the Notes
     completed, or transfer by book-entry transfer, to the Company, a
     Depositary, if appointed by the Company, or a Paying Agent at the address
     specified in the notice at least three days before the Purchase Date;

          (7)  that Holders will be entitled to withdraw their election if the
     Company, the Depositary or the Paying Agent, as the case may be, receives,
     not later than the expiration of the Offer Period, a telegram, facsimile
     transmission or letter setting forth the name of the Holder, the principal
     amount of the Note the Holder delivered for purchase and a statement that
     such Holder is withdrawing his election to have such Note purchased;

          (8)  that, if the aggregate principal amount of Notes and other pari
     passu Indebtedness surrendered by holders thereof exceeds the Offer Amount,
     the Company will select the Notes and other pari passu Indebtedness to be
     purchased on a pro rata basis based on the principal amount of Notes and
     such other PARI PASSU Indebtedness surrendered (with such adjustments as
     may be deemed appropriate by the Company so that only Notes in
     denominations of $1,000, or integral multiples thereof, will be purchased);
     and

          (9)  that Holders whose Notes were purchased only in part will be
     issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered (or transferred by book-entry transfer).

     On or before the Purchase Date, the Company will, to the extent lawful,
accept for payment, on a PRO RATA basis to the extent necessary, the Offer
Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer,
or if less than the Offer Amount has been tendered, all Notes tendered, and will
deliver or cause to be delivered to the Trustee the Notes properly accepted
together with an Officers' Certificate stating that such Notes or portions
thereof were accepted for payment by the Company in accordance with the terms of
this Section

3.09. The Company, the Depositary or the Paying Agent, as the case may be, will
promptly (but in any case not later than five days after the Purchase Date) mail
or deliver to each tendering Holder an amount equal to the purchase price of the
Notes tendered by such Holder and accepted by the Company for purchase, and the
Company will promptly issue a new Note, and the Trustee, upon written request
from the Company, will authenticate and mail or deliver (or cause to be
transferred by book entry) such new Note to such Holder, in a principal amount
equal to any unpurchased portion of the Note surrendered. Any Note not so
accepted shall be promptly mailed or delivered by the Company to the Holder
thereof. The Company will publicly announce the results of the Asset Sale Offer
on the Purchase Date.

     Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

Company.

     (c)  For so long as any Notes remain outstanding, if at any time they are
not required to file with the SEC the reports required by paragraphs (a) and (b)
of this Section 4.03, the Company and the Guarantors will furnish to the Holders

Holders of the Notes.

     The Company and each of the Guarantors covenants (to the extent that it may
lawfully do so) that it will not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Indenture; and the Company and

     or among the Company and any of its Restricted Subsidiaries), except a
     payment of interest or principal at the Stated Maturity thereof; or

time of and after giving effect to such Restricted Payment:

          (1)  no Default or Event of Default has occurred and is continuing or
     would occur as a consequence of such Restricted Payment;

          (2)  the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Debt to Cash Flow Ratio test set forth in Section 4.09(a) hereof; and

          (3)  such Restricted Payment, together with the aggregate amount of
     all other Restricted Payments made by the Company and its Restricted

          financial statements are available at the time of such Restricted
          Payment less the product of 1.5 times the Company's Consolidated
          Interest Expense for the same period; PLUS

               (B)  100% of the aggregate net cash proceeds received by the

          Subsidiary of the Company); PLUS

               (C)  to the extent that any Restricted Investment that was made
          after the date of this Indenture is sold for cash or otherwise
          liquidated or repaid for cash, the lesser of (i) the cash return of
          capital with respect to such Restricted Investment (less the cost of
          disposition, if any) and (ii) the initial amount of such Restricted
          Investment; PLUS

               (D)  to the extent that any Unrestricted Subsidiary of the
          Company designated as such after the date of this Indenture is

          Indenture, the lesser of (i) the Fair Market Value of the Company's
          Investment in such Subsidiary as of the date of such redesignation or
          (ii) such Fair Market Value as of the date on which such Subsidiary
          was originally designated as an Unrestricted Subsidiary after the date

          Subsidiary of the Company that is a Guarantor after the date of this
          Indenture from an Unrestricted Subsidiary of the Company, to the
          extent that such dividends were not otherwise included in the

     (b)  The provisions of Section 4.07(a) hereof will not prohibit:

          (1)  the payment of any dividend or distribution or the consummation
     of any irrevocable redemption within 60 days after the date of declaration
     of the dividend or distribution or giving of the redemption notice, as the
     case may be, if at the date of declaration or notice, the dividend or

     Disqualified Stock) or from the substantially concurrent contribution of
     common equity capital to the Company; PROVIDED that the amount of any such
     net cash proceeds that are utilized for any such Restricted Payment will be
     excluded from clause (3)(B) of Section 4.07(a) hereof;

          (3)  the repurchase, redemption, defeasance or other acquisition or
     retirement for value of Indebtedness of the Company or any Guarantor that
     is contractually subordinated to the Notes or to any Guarantee with the net
     cash proceeds from a substantially concurrent incurrence of Permitted
     Refinancing Indebtedness;

          (4)  the repurchase, redemption or other acquisition or retirement for
     value of any Equity Interests of the Company or any Restricted Subsidiary
     of the Company held by any current or former officer, director or employee
     of the Company or any of its Restricted Subsidiaries pursuant to any equity
     subscription agreement, stock option agreement, shareholders' agreement or
     similar agreement; PROVIDED that the aggregate price paid for all such
     repurchased, redeemed, acquired or retired Equity Interests may not exceed
     $500,000 in any twelve-month period;

Market Value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or

                                       50
<Page>

issued by the Company or such Restricted Subsidiary, as the case may be,
pursuant to the Restricted Payment. The Fair Market Value of any assets or
securities that are required to be valued by this Section 4.07 will be
determined by the Board of Directors of the Company whose resolution with
respect thereto shall be delivered to the Trustee. The Board of Directors'
determination must be based upon an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if the
Fair Market Value exceeds $5.0 million.

Section 4.08   DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

     (a)  The Company will not and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to:

          (1)  pay dividends or make any other distributions on its Capital
     Stock to the Company or any of its Restricted Subsidiaries, or with respect

encumbrances or restrictions existing under or by reason of:

          (1)  agreements or instruments governing Indebtedness incurred
     pursuant to clause (1) of the definition of "Permitted Debt" so long as
     either (a) the encumbrances and restrictions contained therein do not
     impair the ability of any Restricted Subsidiary of the Company to pay
     dividends or make any other distributions or payments directly or
     indirectly to the Company in an amount sufficient to permit the Company to
     pay the principal of, or interest and premium and Liquidated Damages, if
     any, on, the Notes, or (b) the encumbrances or restrictions contained
     therein are no more restrictive, taken as a whole, than those contained in
     the Notes and this Indenture

          (2)  this Indenture, the Notes and the Guarantees;

          (3)  applicable law, rule, regulation or order;

          (4)  any instrument governing Indebtedness or Capital Stock of a
     Person acquired by the Company or any of its Restricted Subsidiaries as in
     effect at the time of such acquisition (except to the extent such
     Indebtedness or Capital Stock was incurred in connection with or in
     contemplation of such acquisition), which encumbrance or restriction is not
     applicable to any Person, or the properties or assets of any Person, other
     than the Person, or the property or assets of the Person, so acquired;
     PROVIDED that, in the case of Indebtedness, such Indebtedness was permitted
     by the terms of this Indenture to be incurred;

                                       51
<Page>

          (5)  customary non-assignment provisions in contracts and licenses
     entered into in the ordinary course of business;

          (6)  purchase money obligations for property acquired in the ordinary
     course of business and Capital Lease Obligations that impose restrictions
     on the property purchased or leased of the nature described in clause (3)
     of Section 4.08(a) hereof;

          (7)  any agreement for the sale or other disposition of a Restricted
     Subsidiary that restricts distributions by that Restricted Subsidiary
     pending the sale or other disposition;

          (8)  Permitted Refinancing Indebtedness; PROVIDED that the
     restrictions contained in the agreements governing such Permitted
     Refinancing Indebtedness are not materially more restrictive, taken as a
     whole, than those contained in the agreements governing the Indebtedness
     being refinanced;

          (9)  Liens permitted to be incurred under the provisions of Section
     4.12 hereof that limit the right of the debtor to dispose of the assets

          (10) provisions limiting the disposition or distribution of assets or
     property in joint venture agreements, asset sale agreements, sale-leaseback
     agreements, stock sale agreements and other similar agreements entered into
     with the approval of the Company's Board of Directors, which limitation is
     applicable only to the assets that are the subject of such agreements; and

          (11) restrictions on cash or other deposits or net worth imposed by
     customers under contracts entered into in the ordinary course of business.

Section 4.09   INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

     (a)  The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, issue, assume, guarantee or
otherwise become directly or indirectly liable, contingently or otherwise, with
respect to (collectively, "INCUR") any Indebtedness and the Company will not
issue any Disqualified Stock and will not permit any of its Restricted
Subsidiaries to issue any shares of preferred stock; PROVIDED, HOWEVER, that the
Company may incur Indebtedness or issue Disqualified Stock, and the Company's
Restricted Subsidiaries that are Guarantors may incur Indebtedness or issue
preferred stock, if, after giving pro forma effect thereto (including a pro
forma application of the net proceeds therefrom), the Company's Debt to Cash
Flow Ratio immediately preceding the incurrence of such additional Indebtedness
or the issuance of such Disqualified Stock or preferred stock, as the case may
be, would have been no greater than 7.0 to 1.

     (b)  The provisions of Section 4.09(a) hereof will not prohibit the
incurrence of any of the following items of Indebtedness (collectively,
"PERMITTED DEBT"):

          (1)  the incurrence by the Company and any of its Restricted
     Subsidiaries of additional Indebtedness and letters of credit in an
     aggregate principal amount at any one time outstanding under this clause
     (1) (with letters of credit being deemed to have a

                                       52
<Page>

     principal amount equal to the maximum potential liability of the Company
     and its Restricted Subsidiaries thereunder), including all Permitted
     Refinancing Indebtedness incurred to extend, renew, refund, refinance,
     replace, defease or discharge any Indebtedness incurred pursuant to this
     clause (1), not to exceed the greater of (a) 1.5 times the Company's
     Consolidated Cash Flow for the most recently ended four full fiscal
     quarters for which internal financial statements are available immediately
     preceding the date on which such additional Indebtedness is incurred and
     (b) $45.0 million;

          (2)  the incurrence by the Company and its Restricted Subsidiaries of
     the Existing Indebtedness;

          (3)  the incurrence by the Company and the Guarantors of Indebtedness
     represented by the Notes and the related Guarantees to be issued on the
     date of this Indenture, and the Exchange Notes and the related Guarantees
     to be issued pursuant to the Registration Rights Agreement;

          (4)  the incurrence by the Company or any of the Guarantors of
     Indebtedness represented by Capital Lease Obligations, mortgage financings
     or purchase money obligations, in each case, incurred for the purpose of
     financing all or any part of the purchase price or cost of design,
     construction, installation or improvement of property, plant or equipment
     used in the business of the Company or any of its Restricted Subsidiaries,
     in an aggregate principal amount, including all Permitted Refinancing
     Indebtedness incurred to extend, renew, refund, refinance, replace, defease
     or discharge any Indebtedness incurred pursuant to this clause (4), not to
     exceed $10.0 million at any time outstanding

          (5)  the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to extend, renew, refund, refinance,
     replace, defease or discharge any Indebtedness (other than intercompany
     Indebtedness) that was permitted by this Indenture to be incurred under
     Section 4.09(a) hereof or clauses (2), (3), (5) or (12) of this Section
     4.09(b);

          (6)  the incurrence by the Company or any of its Restricted
     Subsidiaries of intercompany Indebtedness between or among the Company and
     any of its Restricted Subsidiaries; PROVIDED, HOWEVER, that (a) any
     subsequent issuance or transfer of Equity Interests that results in any
     such Indebtedness being held by a Person other than the Company or a
     Restricted Subsidiary of the Company and (b) any sale or other transfer of
     any such Indebtedness to a Person that is not either the Company or a
     Restricted Subsidiary of the Company, will be deemed, in each case, to
     constitute an incurrence of such Indebtedness by the Company or such
     Restricted Subsidiary, as the case may be, that was not permitted by this
     clause (6);

          (7)  the issuance by any of the Company's Restricted Subsidiaries to
     the Company or to any of its Restricted Subsidiaries of shares of preferred
     stock; PROVIDED, HOWEVER, that:

                                       53
<Page>

               (A)  any subsequent issuance or transfer of Equity Interests that
          results in any such preferred stock being held by a Person other than
          the Company or a Restricted Subsidiary of the Company; and

               (B)  any sale or other transfer of any such preferred stock to a
          Person that is not either the Company or a Restricted Subsidiary of
          the Company,

     will be deemed, in each case, to constitute an issuance of such preferred
     stock by such Restricted Subsidiary that was not permitted by this clause
     (7);

          (8)  the incurrence by the Company or any of its Restricted
     Subsidiaries of Hedging Obligations in the ordinary course of business;

          (9)  the guarantee by the Company or any of the Guarantors of
     Indebtedness of the Company or a Restricted Subsidiary of the Company that
     was permitted to be incurred by another provision of this Section 4.09;
     PROVIDED that if the Indebtedness being guaranteed is subordinated to or
     pari passu with the Notes, then the guarantee shall be subordinated or pari
     passu, as applicable, to the same extent as the Indebtedness guaranteed;

          (10) the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness in respect of workers' compensation claims,
     self-insurance obligations, bankers' acceptances, performance and surety
     bonds in the ordinary course of business;

          (11) the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness arising from the honoring by a bank or other
     financial institution of a check, draft or similar instrument inadvertently
     drawn against insufficient funds, so long as such Indebtedness is covered
     within five Business Days; and

          (12) Acquired Debt incurred at the time a Sprint PCS Affiliate is
     merged with or into or becomes a subsidiary of or transfers all or
     substantially all of its assets to the Company or a Guarantor on or prior
     to December 31, 2005, but only to the extent that immediately after giving
     effect to the incurrence of such Indebtedness (a) the Company's Debt to
     Cash Flow Ratio would have been no greater than 7.75 to 1.0; and (b) the
     Company's Debt to Cash Flow Ratio immediately following such incurrence
     would decrease as compared to the Company's Debt to Cash Flow Ratio
     immediately prior to such incurrence.

     The Company will not incur, and will not permit any Guarantor to incur, any
Indebtedness (including Permitted Debt) that is contractually subordinated in
right of payment to any other Indebtedness of the Company or such Guarantor
unless such Indebtedness is also contractually subordinated in right of payment
to the Notes and the applicable Guarantee on substantially identical terms;
PROVIDED, HOWEVER, that no Indebtedness will be deemed to be contractually
subordinated in right of payment to any other Indebtedness of the Company solely
by virtue of being unsecured or by virtue of being secured on a first or junior
Lien basis.

     For purposes of determining compliance with this Section 4.09, in the event
that an item of proposed Indebtedness meets the criteria of more than one of the
categories of Permitted Debt

                                       54
<Page>

described in clauses (1) through (12) above, or is entitled to be incurred
pursuant to Section 4.09(a) hereof, the Company will be permitted to classify
such item of Indebtedness on the date of its incurrence, or later reclassify all
or a portion of such item of Indebtedness, in any manner that complies with this
Section 4.09. The accrual of interest, the accretion or amortization of original
issue discount, the payment of interest on any Indebtedness in the form of
additional Indebtedness with the same terms, the reclassification of preferred
stock as Indebtedness due to a change in accounting principles, and the payment
of dividends on Disqualified Stock in the form of additional shares of the same
class of Disqualified Stock will not be deemed to be an incurrence of
Indebtedness or an issuance of Disqualified Stock for purposes of this Section
4.09; PROVIDED, in each such case, that the amount of any such accrual,
accretion or payment is included in Consolidated Interest Expense of the Company
as accrued. Notwithstanding any other provision of this Section 4.09, the
maximum amount of Indebtedness that the Company or any Restricted Subsidiary may
incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as
a result of fluctuations in exchange rates or currency values.

     (c)  The amount of any Indebtedness outstanding as of any date will be:

          (1)  the accreted value of the Indebtedness, in the case of any
     Indebtedness issued with original issue discount;

          (2)  the principal amount of the Indebtedness, in the case of any
     other Indebtedness; and

          (3)  in respect of Indebtedness of another Person secured by a Lien on
     the assets of the specified Person, the lesser of:

               (A)  the Fair Market Value of such assets at the date of
          determination; and

               (B)  the amount of the Indebtedness of the other Person.

Section 4.10   ASSET SALES.

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

          (1)  the Company or the Restricted Subsidiary, as the case may be,
     receives consideration at the time of the Asset Sale at least equal to the
     Fair Market Value of the assets or Equity Interests issued or sold or
     otherwise disposed of; and

          (2)  at least 75% of the consideration received in the Asset Sale by
     the Company or such Restricted Subsidiary is in the form of cash or Cash
     Equivalents. For purposes of this provision, each of the following will be
     deemed to be cash:

               (A)  any liabilities, as shown on the Company's most recent
          consolidated balance sheet, of the Company or any Restricted
          Subsidiary (other than contingent liabilities and liabilities that are
          by their terms subordinated to the Notes or any Guarantee) that are
          assumed by the transferee of any such assets

                                       55
<Page>

          pursuant to a customary novation agreement that releases the Company
          or such Restricted Subsidiary from further liability;

               (B)  any securities, notes or other obligations received by the
          Company or any such Restricted Subsidiary from such transferee that
          are contemporaneously, subject to ordinary settlement periods,
          converted by the Company or such Restricted Subsidiary into cash, to
          the extent of the cash received in that conversion; and

               (C)  any stock or assets of the kind referred to in clauses (2)
          or (4) of the next paragraph of this Section 4.10.

     Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Company or the applicable Restricted Subsidiary, as the case may be, may
apply such Net Proceeds:

          (1)  to repay Indebtedness incurred pursuant to clause (1) of the
     definition of "Permitted Debt" (and, if the Indebtedness repaid is
     revolving credit Indebtedness, to correspondingly permanently reduce
     commitments with respect thereto);

          (2)  to acquire all or substantially all of the assets of, or any
     Capital Stock of, another Permitted Business, if, after giving effect to
     any such acquisition of Capital Stock, the Permitted Business is or becomes
     a Restricted Subsidiary of the Company;

          (3)  to make a capital expenditure; or

          (4)  to acquire other assets that are not classified as current assets
     under GAAP and that are used or useful in a Permitted Business.

Pending the final application of any Net Proceeds, the Company may temporarily
reduce revolving credit borrowings or otherwise invest the Net Proceeds in any
manner that is not prohibited by this Indenture.

     Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the second paragraph of this Section 4.10 will constitute "EXCESS
PROCEEDS." When the aggregate amount of Excess Proceeds exceeds $10.0 million,
within 30 days thereof, the Company will make an Asset Sale Offer to all Holders
of Notes and all holders of other Indebtedness that is PARI PASSU with the Notes
containing provisions similar to those set forth in this Indenture with respect
to offers to purchase or redeem with the proceeds of sales of assets to purchase
the maximum principal amount of Notes and such other PARI PASSU Indebtedness
that may be purchased out of the Excess Proceeds. The offer price in any Asset
Sale Offer will be equal to 100% of the principal amount of Notes plus accrued
and unpaid interest and Liquidated Damages, if any, to the date of purchase,
which price will be payable in cash. If any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company may use those Excess Proceeds
for any purpose not otherwise prohibited by this Indenture. If the aggregate
principal amount of Notes and other PARI PASSU Indebtedness tendered into such
Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select
the Notes and such other PARI PASSU Indebtedness to be purchased on a pro rata
basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds
will be reset at zero.

                                       56
<Page>

     The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with each
repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the provisions of

Section 4.15   OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

     (a)  Upon the occurrence of a Change of Control after the Merger, the
Company will make an offer (a "CHANGE OF CONTROL OFFER") to each Holder to

of that Holder's Notes at a purchase price in cash equal to 101% of the
aggregate principal amount of Notes repurchased plus accrued and unpaid interest

will mail a notice to each Holder describing the transaction or transactions
that constitute the Change of Control and stating:

     address specified in the notice prior to the close of business on the third
     Business Day preceding the Change of Control Payment Date;

          (6)  that Holders will be entitled to withdraw their election if the
     Paying Agent receives, not later than the close of business on the second
     Business Day preceding the Change of Control Payment Date, a telegram,

     principal amount of Notes delivered for purchase, and a statement that such
     Holder is withdrawing his election to have the Notes purchased; and

     (b)  On the Change of Control Payment Date, the Company will, to the extent

          (1)  accept for payment all Notes or portions of Notes properly
     tendered pursuant to the Change of Control Offer;

          (2)  deposit with the Paying Agent an amount equal to the Change of
     Control Payment in respect of all Notes or portions of Notes properly
     tendered; and

          (3)  deliver or cause to be delivered to the Trustee the Notes
     properly accepted together with an Officers' Certificate stating the

tendered the Change of Control Payment for such Notes, and the Trustee will

Company will not be required to make a Change of Control Offer upon a Change of
Control if (1) a third party makes the Change of Control Offer in the manner, at
the times and otherwise in compliance with the requirements set forth in this
Section 4.15 and purchases all Notes properly tendered and not withdrawn under

Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder of Notes for or as an

another Domestic Restricted Subsidiary after the date of this Indenture, then
that newly acquired or created Domestic Restricted Subsidiary will become a
Guarantor and execute a supplemental indenture in the form of Exhibit F hereto
and deliver an Opinion of Counsel satisfactory to the Trustee within ten
Business Days of the date on which it was acquired or created; PROVIDED that any
Domestic Restricted Subsidiary that constitutes an Immaterial Subsidiary need
not become a

                                       60
<Page>

Guarantor until such time as it ceases to be an Immaterial Subsidiary The form

Section 4.18   DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES.

     The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if that designation would not cause
a Default. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned
by the Company and its Restricted Subsidiaries in the Subsidiary designated as
Unrestricted will be deemed to be an Investment made as of the time of the
designation and will reduce the amount available for Restricted Payments under
Section 4.07 hereof or under one or more clauses of the definition of Permitted
Investments, as determined by the Company. That designation will only be
permitted if the Investment would be permitted at that time and if the
Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. The Board of Directors of the Company may redesignate any
Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation
would not cause a Default.

     Any designation of a Subsidiary of the Company as an Unrestricted
Subsidiary will be evidenced to the Trustee by filing with the Trustee a
certified copy of a resolution of the Board of Directors giving effect to such
designation and an Officers' Certificate certifying that such designation
complied with the preceding conditions and was permitted by Section 4.07 hereof.
If, at any time, any Unrestricted Subsidiary would fail to meet the preceding
requirements as an Unrestricted Subsidiary, it will thereafter cease to be an
Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of
such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the
Company as of such date and, if such Indebtedness is not permitted to be
incurred as of such date under Section 4.09 hereof, the Company will be in
default of such covenant. The Board of Directors of the Company may at any time
designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the
Company; PROVIDED that such designation will be deemed to be an incurrence of
Indebtedness by a Restricted Subsidiary of the Company of any outstanding
Indebtedness of such Unrestricted Subsidiary, and such designation will only be
permitted if (1) such Indebtedness is permitted under Section 4.09 hereof,
calculated on a pro forma basis as if such designation had occurred at the
beginning of the four-quarter reference period; and (2) no Default or Event of
Default would be in existence following such designation.

Section 6.02   ACCELERATION.

     In the case of an Event of Default specified in clause (10) or (11) of
Section 6.01 hereof, with respect to the Company, any Restricted Subsidiary of
the Company that is a Significant Subsidiary or any group of Restricted
Subsidiaries of the Company that, taken together, would constitute a Significant
Subsidiary, all outstanding Notes will become due and payable immediately
without further action or notice. If any other Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately. Upon any such declaration, the Notes shall become due and
payable immediately.

     The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, rescind an acceleration and its consequences, if the rescission would
not conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium or Liquidated Damages, if
any, that has become due solely because of the acceleration) have been cured or
waived.

     If an Event of Default occurs on or after May 1, 2008 by reason of any
willful action (or inaction) taken (or not taken) by or on behalf of the Company
with the intention of avoiding payment of the premium that the Company would
have had to pay if the Company then had elected to redeem the Notes pursuant to
Section 3.07 hereof, then, upon acceleration of the Notes, a premium equal to
the premium that the Company would have had to pay if the Company then had
elected to redeem the Notes pursuant to Section 3.07 hereof shall, in addition
to such other amounts required to be paid in connection with such acceleration,
become and be immediately due and payable, to the extent permitted by law,
anything in this Indenture or in the Notes to the contrary notwithstanding. If
an Event of Default occurs prior to May 1, 2008, by reason of any willful action
(or inaction) taken (or not taken) by or on behalf of the Company with the
intention of avoiding the prohibition on redemption of the Notes prior to such
date, then, upon acceleration of the Notes, a premium, in addition to such other
amounts required to be paid in connection with such acceleration, shall become
and be immediately due and payable, to the extent permitted by law, in an
amount, for each of the years beginning on May 1 of the years set forth below,
as set forth below (expressed as a percentage of the principal amount of the
Notes on the date of payment that would otherwise be due but for the provisions
of this sentence):

The Trustee shall not be deemed to have knowledge that a premium is due under
this Section 6.02 unless written notice of an Event of Default is delivered to
the Trustee under Section 4.04(c) hereof at any time prior to May 1, 2008. The
Trustee shall not be deemed to have knowledge that a premium is due under this
Section 6.02 unless a Responsible Officer has received written notice to such
effect.

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, premium and Liquidated
Damages, if any, and interest on the Notes or to enforce the performance of any
provision of the Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder of a Note 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. All remedies are
cumulative to the extent permitted by law.

Section 6.04   WAIVER OF PAST DEFAULTS.

     Holders of not less than a majority in aggregate principal amount of the
then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium and Liquidated Damages, if any, or interest
on, the Notes (including in connection with an offer to purchase); PROVIDED,
HOWEVER, that the Holders of a majority in aggregate principal amount of the
then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration. Upon
any such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

Section 6.05   CONTROL BY MAJORITY.

     Holders of a majority in aggregate principal amount of the then outstanding
Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

Section 6.06   LIMITATION ON SUITS.

     A Holder may pursue a remedy with respect to this Indenture or the Notes
only if:

          (1)  such Holder has previously given the Trustee notice that an Event
     of Default is continuing;

          (2)  Holders of at least 25% in aggregate principal amount of the then
     outstanding Notes have requested that the Trustee pursue the remedy;

          (3)  such Holder or Holders have offered the Trustee reasonable
     security or indemnity against any loss, liability or expense;

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

          (5)  during such 60-day period, Holders of a majority in aggregate
     principal amount of the then outstanding Notes have not given the Trustee a
     direction inconsistent with such request.

     A Holder of a Note may not use this Indenture to prejudice the rights of
another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

Section 6.07   RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

     Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Liquidated
Damages, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08   COLLECTION SUIT BY TRUSTEE.

     If an Event of Default specified in Section 6.01(1) or (2) hereof occurs
and is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Company for the whole amount of
principal of, premium and Liquidated Damages, if any, and interest remaining
unpaid on, the Notes and interest on overdue principal and, to the extent
lawful, interest and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09   TRUSTEE MAY FILE PROOFS OF CLAIM.

     The Trustee is authorized to 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 (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled

                                       67
<Page>

and empowered to collect, receive and distribute any money or other property
payable or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such 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 to it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10   PRIORITIES.

     If the Trustee collects any money pursuant to this Article 6, it shall pay
out the money in the following order:

          FIRST:    to the Trustee, its agents and attorneys for amounts due
     under Section 7.07 hereof, including payment of all compensation, expenses
     and liabilities incurred, and all advances made, by the Trustee and the
     costs and expenses of collection;

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

          THIRD:    to the Company or to such party as a court of competent
     jurisdiction shall direct.

     The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

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 a
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 of a Note pursuant
to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate
principal amount of the then outstanding Notes.

                                     TRUSTEE

Section 7.01   DUTIES OF TRUSTEE.

     (a)  If an Event of Default has occurred and is continuing, the Trustee
will exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in its 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 duties of the Trustee will be determined solely by the
     express provisions of this Indenture and the Trustee need perform only
     those duties that are specifically set forth in this Indenture and no
     others, 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 will examine the certificates and opinions to determine whether
     or not they conform to the requirements of this Indenture.

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

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

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

          (3)  the Trustee will 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 hereof.

     (d)  Whether or not therein expressly so provided, 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)  No provision of this Indenture will require the Trustee to expend or
risk its own funds or incur any liability. The Trustee will be under no
obligation to exercise any of its rights and powers under this Indenture at the
request of any Holders, unless such Holder has offered to the Trustee security
and indemnity satisfactory to it against any loss, liability or expense.

                                       69
<Page>

     (f)  The Trustee will not be liable for interest on any money received by
it except as the Trustee may agree in writing with the Company. Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

Section 7.02   RIGHTS OF TRUSTEE.

     (a)  The Trustee may conclusively rely upon any document believed by it to
be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document.

     (b)  Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel or both. The Trustee will not be
liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel of its selection and the advice of such counsel or any Opinion of
Counsel will be full and complete authorization and protection from liability in
respect of any action taken, suffered or omitted by it hereunder in good faith
and in reliance thereon.

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

take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

     (e)  Unless otherwise specifically provided in this Indenture, any demand,
request, direction or notice from the Company will be sufficient if signed by an
Officer of the Company.

     (f)  The Trustee will be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Holders unless such Holders have offered to the Trustee reasonable indemnity
or security reasonably satisfactory to the Trustee against the losses,
liabilities and expenses that might be incurred by it in compliance with such
request or direction.

     (g)  In no event shall the Trustee be responsible or liable for special,
indirect, or consequential loss or damage of any kind whatsoever (including, but
not limited to, loss of profit) irrespective of whether the Trustee has been
advised of the likelihood of such loss or damage and regardless of the form of
action;

     (h) The Trustee shall not be deemed to have notice of any Default or Event
of Default unless a Responsible Officer of the Trustee has actual knowledge

received by the Trustee at the Corporate Trust Office of the Trustee, and such
notice references the Notes and this Indenture.

     (i)  The rights, privileges, protections, immunities and benefits given to
the Trustee, including, without limitation, its right to be indemnified, are
extended to, and shall be enforceable by, the Trustee in each of its capacities
hereunder, and each agent, custodian and other Person employed to act hereunder.

                                       70

     (j)  The Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture.

Section 7.03   INDIVIDUAL RIGHTS OF TRUSTEE.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may otherwise deal with the Company or any Affiliate of the
Company with the same rights it would have if it were not Trustee. However, in
the event that the Trustee acquires any conflicting interest (as defined in the
TIA) it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as trustee (if this Indenture has been qualified under
the TIA) or resign. Any Agent may do the same with like rights and duties. The
Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04   TRUSTEE'S DISCLAIMER.

     The Trustee will not be responsible for and makes no representation as to
the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it will not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it will not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

Section 7.05   NOTICE OF DEFAULTS.

     If a Default or Event of Default occurs and is continuing and if it is
actually known to a Responsible Officer of the Trustee, the Trustee will mail to
Holders of Notes a notice of the Default or Event of Default within 90 days
after it occurs. Except in the case of a Default or Event of Default in payment
of principal of, premium or Liquidated Damages, if any, or interest on, any
Note, the Trustee may withhold the notice if and so long as a committee of its
Responsible Officers in good faith determines that withholding the notice is in
the interests of the Holders of the Notes.

Section 7.06   REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

     (a)  Within 60 days after each February 15 beginning with the February 15
following the date of this Indenture, and for so long as Notes remain
outstanding, the Trustee will mail to the Holders of the Notes a brief report
dated as of such reporting date that complies with TIA Section 313(a) (but if no
event described in TIA Section 313(a) has occurred within the twelve months
preceding the reporting date, no report need be transmitted). The Trustee also
will comply with TIA Section 313(b)(2). The Trustee will also transmit by mail
all reports as required by TIA Section 313(c).

     (b)  A copy of each report at the time of its mailing to the Holders of
Notes will be mailed by the Trustee to the Company and filed by the Trustee with
the SEC and each stock exchange on which the Notes are listed in accordance with
TIA Section 313(d). The Company will promptly notify the Trustee when the Notes
are listed on or delisted from any stock exchange.

                                       71

Section 7.07   COMPENSATION AND INDEMNITY.

     (a)  The Company will pay to the Trustee from time to time such
compensation for its acceptance of this Indenture and services hereunder as
shall be agreed in writing by the Company and the Trustee. The Trustee's
compensation will not be limited by any law on compensation of a trustee of an
express trust. The Company will reimburse the Trustee promptly upon request for
all reasonable disbursements, advances and expenses incurred or made by it in
addition to the compensation for its services. Such expenses will include the
reasonable compensation, disbursements and expenses of the Trustee's agents and
counsel.

     (b)  The Company and the Guarantors will indemnify the Trustee and any
predecessor Trustee against any and all losses, liabilities, damages, claims or
expenses, including taxes (other than those based upon, measured by or
determined by the income of the Trustee) incurred by it arising out of or in
connection with the acceptance or administration of its duties under this
Indenture, including the costs and expenses of enforcing this Indenture against
the Company and the Guarantors (including this Section 7.07) and defending
itself against any claim (whether asserted by the Company, the Guarantors, any
Holder or any other Person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, except to the extent any
such loss, liability or expense may be attributable to its negligence or bad
faith. The Trustee will notify the Company promptly of any claim for which it
may seek indemnity. Failure by the Trustee to so notify the Company will not
relieve the Company or any of the Guarantors of their obligations hereunder. The
Company or such Guarantor will defend the claim and the Trustee will cooperate
in the defense. The Trustee may have separate counsel and the Company will pay
the reasonable fees and expenses of such counsel. Neither the Company nor any
Guarantor need pay for any settlement made without its consent, which consent
will not be unreasonably withheld.

     (c)  The obligations of the Company and the Guarantors under this Section
7.07 will survive the satisfaction and discharge of this Indenture and the
resignation or removal of the Trustee.

     (d)  To secure the Company's and the Guarantors' payment obligations in
this Section 7.07, the Trustee will have a Lien prior to the Notes on all money
or property held or collected by the Trustee, except that held in trust to pay
principal and interest on particular Notes. Such Lien will constitute a
Permitted Lien and will survive the satisfaction and discharge of this
Indenture.

     (e)  When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(10) or (11) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its agents
and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

     (f)  The Trustee will comply with the provisions of TIA Section 313(b)(2)
to the extent applicable.

Trustee will become effective only upon the successor Trustee's acceptance of

     (b)  The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of a majority
in aggregate principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company may
remove the Trustee if:

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

          (2)  the Trustee is adjudged a bankrupt or an insolvent or an order
     for relief is entered with respect to the Trustee under any Bankruptcy Law;

          (3)  a custodian or public officer takes charge of the Trustee or its

          (4)  the Trustee becomes incapable of acting.

     (c)  If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company will promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in aggregate principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

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

     (e)  If the Trustee, after written request by any Holder who has been a
Holder for at least six months, fails to comply with Section 7.10 hereof, such
Holder may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

     (f)  A successor Trustee will deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the
successor Trustee will have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee will mail a notice of its succession
to Holders. The retiring Trustee will promptly transfer all property held by it
as Trustee to the successor Trustee; PROVIDED all sums owing to the Trustee
hereunder have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 hereof will continue for the
benefit of the retiring Trustee.

Section 7.09   SUCCESSOR TRUSTEE BY MERGER, ETC.

     If the Trustee consolidates, merges or converts into, or transfers all or
substantially all of its corporate trust business to, another corporation, the
successor corporation without any further act will be the successor Trustee.

Section 7.10   ELIGIBILITY; DISQUALIFICATION.

     There will at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100.0
million as set forth in its most recent published annual report of condition.

     This Indenture will always have a Trustee who satisfies the requirements of
TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section
310(b).

Section 7.11   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     The Trustee is subject to TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

Section 7.12   PATRIOT ACT.

     To help the government fight the funding of terrorism and money laundering
activities, federal law requires all financial institutions to obtain, verify
and record information that identifies each person who opens an account. For a
non-individual person such as a business entity, a charity, a trust or other
legal entity the Trustee will ask for documentation to verify its formation and
existence as a legal entity. The Trustee may also ask to see financial
statements, licenses, identification and authorization documents from
individuals claiming authority to represent the entity or other relevant
documentation.

Section 7.13   PAYMENT OF LIQUIDATED DAMAGES.

     If Liquidated Damages are payable, the Company shall deliver to the Trustee
a certificate to that effect stating (a) the amount of such Liquidated Damages
that are payable and (b) the date on which such Liquidated Damages are payable.
Unless and until a Responsible Officer of the Trustee receives at the Corporate
Trust Office such a certificate, the Trustee may assume without inquiry that no
such Liquidated Damages are payable. If the Company has paid Liquidated Damages
directly to the persons entitled to them, the Company shall deliver to the
Trustee a certificate setting forth the particulars of such payment.

hereunder:

          (1)  the rights of Holders of outstanding Notes to receive payments in

subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be released from each of their obligations under the covenants contained in
Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17 and 4.18
hereof and clause (4) of Section 5.01 hereof with respect to the outstanding
Notes on and after

                                       75
<Page>

the date the conditions set forth in Section 8.04 hereof are satisfied
(hereinafter, "COVENANT DEFEASANCE"), and the Notes will thereafter be deemed
not "outstanding" for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but will continue to be deemed "outstanding" for
all other purposes hereunder (it being understood that such Notes will not be
deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Notes and Guarantees, the
Company and the Guarantors may omit to comply with and will have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply will
not constitute a Default or an Event of Default under Section 6.01 hereof, but,
except as specified above, the remainder of this Indenture and such Notes and
Guarantees will be unaffected thereby. In addition, upon the Company's exercise
under Section 8.01 hereof of the option applicable to this Section 8.03, subject
to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(3) through 6.01(5) hereof will not constitute Events of Default.

Section 8.04   CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

     In order to exercise either Legal Defeasance or Covenant Defeasance under
either Section 8.02 or 8.03 hereof:

          (1)  the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders of the Notes, cash in U.S. dollars,
     non-callable Government Securities, or a combination of cash in U.S.
     dollars and non-callable Government Securities, in amounts as will be
     sufficient, in the opinion of a nationally recognized investment bank,
     appraisal firm or firm of independent public accountants, to pay the
     principal of, or interest and premium and Liquidated Damages, if any, on,
     the outstanding Notes on the stated date for payment thereof or on the
     applicable redemption date, as the case may be, and the Company must
     specify whether the Notes are being defeased to such stated date for
     payment or to a particular redemption date;

          (2)  in the case of an election under Section 8.02 hereof, the Company
     must deliver to the Trustee an Opinion of Counsel confirming that:

               (A)  the Company has received from, or there has been published
          by, the Internal Revenue Service a ruling; or

               (B)  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 Holders of the outstanding Notes will not recognize
income, gain or loss for federal income tax purposes as a result of such Legal
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 Legal
Defeasance had not occurred;

                                       76
<Page>

          (3)  in the case of an election under Section 8.03 hereof, the Company
     must deliver to the Trustee an Opinion of Counsel reasonably acceptable to
     the Trustee confirming that the Holders of the outstanding Notes 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;

          (4)  no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such
     deposit) and the deposit will not result in a breach or violation of, or
     constitute a default under, any other instrument to which the Company or
     any Guarantor is a party or by which the Company or any Guarantor is bound;

          (5)  such Legal Defeasance or Covenant Defeasance will not result in a
     breach or violation of, or constitute a default under, any material
     agreement or instrument (other than this Indenture) to which the Company or
     any of its Subsidiaries is a party or by which the Company or any of its
     Subsidiaries is bound;

          (6)  the Company must deliver to the Trustee an Officers' Certificate
     stating that the deposit was not made by the Company with the intent of
     preferring the Holders of Notes over the other creditors of the Company
     with the intent of defeating, hindering, delaying or defrauding any
     creditors of the Company or others; and

          (7)  the Company must deliver to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     relating to the Legal Defeasance or the Covenant Defeasance have been
     complied with.

     Notwithstanding the foregoing, the Opinion of Counsel required by clause
(2) above with respect to a Legal Defeasance need not be delivered if all Notes
not theretofore delivered to the Trustee for cancellation (1) have become due
and payable or (2) will become due and payable on the maturity date 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.

Section 8.05   DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST;
               OTHER MISCELLANEOUS PROVISIONS.

     Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"TRUSTEE") pursuant to Section 8.04 hereof in respect of the outstanding Notes
will be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium and Liquidated Damages, if
any, and interest, but such money need not be segregated from other funds except
to the extent required by law.

                                       77
<Page>

     The Company will pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes.

     Notwithstanding anything in this Article 8 to the contrary, the Trustee
will deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(1) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06   REPAYMENT TO COMPANY.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium or Liquidated
Damages, if any, or interest on, any Note and remaining unclaimed for two years
after such principal, premium or Liquidated Damages, if any, or interest has
become due and payable shall (subject to applicable escheat law) be paid to the
Company on its request or (if then held by the Company) will be discharged from
such trust; and the Holder of such Note will thereafter be permitted to look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, will thereupon cease; PROVIDED, HOWEVER, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified therein, which will not be
less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining will be repaid to the Company.

Section 8.07   REINSTATEMENT.

     If the Trustee or Paying Agent is unable to apply any U.S. dollars or
non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and the Guarantors' obligations under this
Indenture and the Notes and the Guarantees will be revived and reinstated as
though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 8.02 or 8.03 hereof, as the case may be; PROVIDED,
HOWEVER, that, if the Company makes any payment of principal of, premium or
Liquidated Damages, if any, or interest on, any Note following the reinstatement
of its obligations, the Company will be subrogated to the rights of the Holders
of such Notes to receive such payment from the money held by the Trustee or
Paying Agent.

                                    ARTICLE 9
                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01   WITHOUT CONSENT OF HOLDERS OF NOTES.

     Notwithstanding Section 9.02 hereof, the Company, the Guarantors and the
Trustee may amend or supplement this Indenture or the Notes or the Guarantees
without the consent of any Holder of Note:

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

          (2)  to provide for uncertificated Notes in addition to or in place of
     certificated Notes;

          (3)  to provide for the assumption of the Company's or a Guarantor's
     obligations under this Indenture, the Notes and the Guarantees in the case
     of a merger or consolidation or sale of all or substantially all of the
     Company's or such Guarantor's assets;

          (4)  to make any change that would provide any additional rights or
     benefits to the Holders of the Notes or that does not adversely affect the
     legal rights hereunder of any Holder;

          (5)  to comply with requirements of the SEC in order to effect or
     maintain the qualification of this Indenture under the TIA;

          (6)  to conform the text of this Indenture, the Notes or the
     Guarantees to any provision of the "Description of Notes" section of the
     Offering Circular, relating to the initial offering of the Notes, to the
     extent that such provision in that "Description of Notes" was intended to
     be a verbatim recitation of a provision of this Indenture, the Notes or the
     Guarantees;

          (7)  to provide for the issuance of Additional Notes in accordance
     with the limitations set forth in this Indenture as of the date hereof; or

          (8)  to allow any Guarantor to execute a supplemental indenture and/or
     a Guarantee with respect to the Notes.

     Upon the request of the Company accompanied by a resolution of its Board of
Directors authorizing the execution of any such amended or supplemental
indenture, and upon receipt by the Trustee of the documents described in Section
9.06 hereof, the Trustee will join with the Company and the Guarantors in the
execution of any amended or supplemental indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee will not be
obligated to enter into such amended or supplemental indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

                                       79
<Page>

Section 9.02   WITH CONSENT OF HOLDERS OF NOTES.

     Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture (including, without limitation, Section
3.09, 4.10 and 4.15 hereof) and the Notes and the Guarantees with the consent of
the Holders of at least a majority in aggregate principal amount of the then
outstanding Notes (including, without limitation, Additional Notes, if any)
voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the
Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or
Event of Default (other than a Default or Event of Default in the payment of the
principal of, premium or Liquidated Damages, if any, or interest on, the Notes,
except a payment default resulting from an acceleration that has been rescinded)
or compliance with any provision of this Indenture or the Notes or the
Guarantees may be waived with the consent of the Holders of a majority in
aggregate principal amount of the then outstanding Notes (including, without
limitation, Additional Notes, if any) voting as a single class (including,
without limitation, consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall
determine which Notes are considered to be "outstanding" for purposes of this
Section 9.02.

     Upon the request of the Company accompanied by a resolution of its Board of
Directors authorizing the execution of any such amended or supplemental
indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 9.06 hereof, the Trustee will
join with the Company and the Guarantors in the execution of such amended or
supplemental indenture unless such amended or supplemental indenture directly
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but will not be
obligated to, enter into such amended or supplemental Indenture.

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

     After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Company will mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, will not, however, in
any way impair or affect the validity of any such amended or supplemental
indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding voting as a
single class may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes or the Guarantees. However, without
the consent of each Holder affected, an amendment, supplement or waiver under
this Section 9.02 may not (with respect to any Notes held by a non-consenting
Holder):

          (1)  reduce the principal amount of Notes whose Holders must consent
     to an amendment, supplement or waiver;

                                       80
<Page>

          (2)  reduce the principal of or change the fixed maturity of any Note
     or alter or waive any of the provisions with respect to the redemption of
     the Notes (except as provided above with respect to Sections 3.09, 4.10 and
     4.15 hereof);

          (3)  reduce the rate of or change the time for payment of interest,
     including default interest, on any Note;

          (4)  waive a Default or Event of Default in the payment of principal
     of, or premium or Liquidated Damages, if any, or interest on, the Notes
     (except a rescission of acceleration of the Notes by the Holders of at
     least a majority in aggregate principal amount of the then outstanding
     Notes and a waiver of the payment default that resulted from such
     acceleration);

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

          (6)  make any change in the provisions of this Indenture relating to
     waivers of past Defaults or the rights of Holders of Notes to receive
     payments of principal of, or interest or premium or Liquidated Damages, if
     any, on, the Notes;

          (7)  waive a redemption payment with respect to any Note (other than a
     payment required by Sections 3.09, 4.10 or 4.15 hereof);

          (8)  release any Guarantor from any of its obligations under its
     Guarantee or this Indenture, except in accordance with the terms of this
     Indenture; or

          (9)  make any change in the preceding amendment and waiver provisions.

Section 9.03   COMPLIANCE WITH TRUST INDENTURE ACT.

     Every amendment or supplement to this Indenture or the Notes will be set
forth in a amended or supplemental indenture that complies with the TIA as then
in effect.

Section 9.04   REVOCATION AND EFFECT OF CONSENTS.

     Until an amendment, supplement or waiver becomes effective, a consent to it
by a Holder of a Note is a continuing consent by the Holder of a Note and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note, even if notation of the consent is not made on any
Note. An amendment, supplement or waiver becomes effective in accordance with
its terms and thereafter binds every Holder.

Section 9.05   NOTATION ON OR EXCHANGE OF NOTES.

     The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

                                       81
<Page>

     Failure to make the appropriate notation or issue a new Note will not
affect the validity and effect of such amendment, supplement or waiver.

Section 9.06   TRUSTEE TO SIGN AMENDMENTS, ETC.

     The Trustee will sign any amended or supplemental indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign an amended or supplemental indenture until the Board of Directors
of the Company approves it. In executing any amended or supplemental indenture,
the Trustee will be entitled to receive and (subject to Section 7.01 hereof)
will be fully protected in relying upon, in addition to the documents required
by Section 12.04 hereof, an Officers' Certificate and an Opinion of Counsel
stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

                                   ARTICLE 10
                                   GUARANTEES

Section 10.01  GUARANTEE.

     (a)  Subject to this Article 10, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to each Holder of a Note authenticated and
delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes or
the obligations of the Company hereunder or thereunder, that:

          (1)  the principal of, premium and Liquidated Damages, if any, and
     interest on, the Notes will be promptly paid in full when due, whether at
     maturity, by acceleration, redemption or otherwise, and interest on the
     overdue principal of and interest on the Notes, if any, if lawful, and all
     other obligations of the Company to the Holders or the Trustee hereunder or
     thereunder will be promptly paid in full or performed, all in accordance
     with the terms hereof and thereof; and

          (2)  in case of any extension of time of payment or renewal of any
     Notes or any of such other obligations, that same will be promptly paid in
     full when due or performed in accordance with the terms of the extension or
     renewal, whether at stated maturity, by acceleration or otherwise.

     Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors will be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

     (b)  The Guarantors hereby agree that their obligations hereunder are
unconditional, irrespective of the validity, regularity or enforceability of the
Notes or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes with respect to any provisions
hereof or thereof, the recovery of any judgment against the Company, any action
to enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. Each Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court
in the event of insolvency or

                                       82
<Page>

bankruptcy of the Company, any right to require a proceeding first against the
Company, protest, notice and all demands whatsoever and covenant that this
Guarantee will not be discharged except by complete performance of the
obligations contained in the Notes and this Indenture.

     (c)  If any Holder or the Trustee is required by any court or otherwise to
return to the Company, the Guarantors or any custodian, trustee, liquidator or
other similar official acting in relation to either the Company or the
Guarantors, any amount paid by either to the Trustee or such Holder, this
Guarantee, to the extent theretofore discharged, will be reinstated in full
force and effect.

     (d)  Each Guarantor agrees that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (1) the maturity of the
obligations guaranteed hereby may be accelerated as provided in Article 6 hereof
for the purposes of this Guarantee notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any declaration of acceleration of
such obligations as provided in Article 6 hereof, such obligations (whether or
not due and payable) will forthwith become due and payable by the Guarantors for
the purpose of this Guarantee. The Guarantors will have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right
does not impair the rights of the Holders under the Guarantee.

Section 10.02  LIMITATION ON GUARANTOR LIABILITY.

     Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Guarantee of such
Guarantor not constitute a fraudulent transfer or conveyance for purposes of
Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar federal or state law to the extent applicable to any
Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and
the Guarantors hereby irrevocably agree that the obligations of such Guarantor
will be limited to the maximum amount that will, after giving effect to such
maximum amount and all other contingent and fixed liabilities of such Guarantor
that are relevant under such laws, and after giving effect to any collections
from, rights to receive contribution from or payments made by or on behalf of
any other Guarantor in respect of the obligations of such other Guarantor under
this Article 10, result in the obligations of such Guarantor under its Guarantee
not constituting a fraudulent transfer or conveyance.

Section 10.03  EXECUTION AND DELIVERY OF GUARANTEE.

     To evidence its Guarantee set forth in Section 10.01 hereof, each Guarantor
hereby agrees that a notation of such Guarantee substantially in the form
attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on
each Note authenticated and delivered by the Trustee and that this Indenture
will be executed on behalf of such Guarantor by one of its Officers.

                                       83
<Page>

     Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01
hereof will remain in full force and effect notwithstanding any failure to
endorse on each Note a notation of such Guarantee.

     If an Officer whose signature is on this Indenture or on the Guarantee no
longer holds that office at the time the Trustee authenticates the Note on which
a Guarantee is endorsed, the Guarantee will be valid nevertheless.

     The delivery of any Note by the Trustee, after the authentication thereof
hereunder, will constitute due delivery of the Guarantee set forth in this
Indenture on behalf of the Guarantors.

     In the event that the Company or any of its Restricted Subsidiaries creates
or acquires any Domestic Restricted Subsidiary after the date of this Indenture,
if required by Section 4.17 hereof, the Company will cause such Domestic
Restricted Subsidiary to comply with the provisions of Section 4.17 hereof and
this Article 10, to the extent applicable.

Section 10.04  GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

     Except as otherwise provided in Section 10.05 hereof, no Guarantor may sell
or otherwise dispose of all or substantially all of its assets to, or
consolidate with or merge with or into (whether or not such Guarantor is the
surviving Person) another Person, other than the Company or another Guarantor,
unless:

          (1)  immediately after giving effect to such transaction, no Default
     or Event of Default exists; and

          (2)  either:

               (a)  subject to Section 10.05 hereof, the Person acquiring the
     property in any such sale or disposition or the Person formed by or
     surviving any such consolidation or merger unconditionally assumes all the
     obligations of that Guarantor under this Indenture, its Guarantee and the
     Registration Rights Agreement on the terms set forth herein or therein,
     pursuant to a supplemental indenture in form and substance reasonably
     satisfactory to the Trustee; or

               (b)  the Net Proceeds of such sale or other disposition are
     applied in accordance with the applicable provisions of this Indenture,
     including without limitation, Section 4.10 hereof.

     In case of any such consolidation, merger, sale or conveyance and upon the
assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the
Guarantee endorsed upon the Notes and the due and punctual performance of all of
the covenants and conditions of this Indenture to be performed by the Guarantor,
such successor Person will succeed to and be substituted for the Guarantor with
the same effect as if it had been named herein as a Guarantor. Such successor
Person thereupon may cause to be signed any or all of the Guarantees to be
endorsed upon all of the Notes issuable hereunder which theretofore shall not
have been signed by the Company and delivered to the Trustee. All the Guarantees
so issued will in all respects have the same legal rank and benefit

                                       84
<Page>

under this Indenture as the Guarantees theretofore and thereafter issued in
accordance with the terms of this Indenture as though all of such Guarantees had
been issued at the date of the execution hereof.

     Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses
2(a) and (b) above, nothing contained in this Indenture or in any of the Notes
will prevent any consolidation or merger of a Guarantor with or into the Company
or another Guarantor, or will prevent any sale or conveyance of the property of
a Guarantor as an entirety or substantially as an entirety to the Company or
another Guarantor.

Section 10.05  RELEASES.

     (a)  In the event of any sale or other disposition of all or substantially
all of the assets of any Guarantor, (including by way of merger or
consolidation) or a sale or other disposition of all of the Capital Stock of any
Guarantor to a Person that is not (either before or after giving effect to such
transactions) the Company or a Restricted Subsidiary of the Company, then such
Guarantor (in the event of a sale or other disposition, by way of merger,
consolidation or otherwise, of all of the Capital Stock of such Guarantor) or
the corporation acquiring the property (in the event of a sale or other
disposition of all or substantially all of the assets of such Guarantor) will be
released and relieved of any obligations under its Guarantee; PROVIDED that the
Net Proceeds of such sale or other disposition are applied in accordance with

execute any documents reasonably required in order to evidence the release of
any Guarantor from its obligations under its Guarantee.

     (b)  Upon designation of any Guarantor, as an Unrestricted Subsidiary in
accordance with the terms of this Indenture, such Guarantor will be released and
relieved of any obligations under its Guarantee.

     (c)  Upon Legal Defeasance in accordance with Article 8 hereof or
satisfaction and discharge of this Indenture in accordance with Article 11
hereof, each Guarantor will be released and relieved of any obligations under
its Guarantee.

     Any Guarantor not released from its obligations under its Guarantee as
provided in this Section 10.05 will remain liable for the full amount of
principal of and interest and premium and Liquidated Damages, if any, on the
Notes and for the other obligations of any Guarantor under this Indenture as
provided in this Article 10.

                           SATISFACTION AND DISCHARGE

Section 11.01  SATISFACTION AND DISCHARGE.

     This Indenture will be discharged and will cease to be of further effect as
to all Notes issued hereunder, when:

                                       85
<Page>

          (1)  either:

               (a)  all Notes that have been authenticated, except lost, stolen
     or destroyed Notes that have been replaced or paid and Notes for whose
     payment money has been deposited in trust and thereafter repaid to the
     Company have been delivered to the Trustee for cancellation; or

               (b)  all Notes that have not been delivered to the Trustee for
     cancellation have become due and payable by reason of the mailing of a
     notice of redemption or otherwise or will become due and payable within one
     year and the Company or any Guarantor has irrevocably deposited or caused
     to be deposited with the Trustee as trust funds in trust solely for the
     benefit of the Holders, cash in U.S. dollars, non-callable Government
     Securities, or a combination of cash in U.S. dollars and non-callable
     Government Securities, in amounts as will be sufficient, without
     consideration of any reinvestment of interest, to pay and discharge the
     entire Indebtedness on the Notes not delivered to the Trustee for
     cancellation for principal, premium and Liquidated Damages, if any, and
     accrued interest to the date of maturity or redemption;

          (2)  no Default or Event of Default has occurred and is continuing on
     the date of the deposit (other than a Default or Event of Default resulting
     from the borrowing of funds to be applied to such deposit) and the deposit
     will not result in a breach or violation of, or constitute a default under,
     any other instrument to which the Company or any Guarantor is a party or by
     which the Company or any Guarantor is bound;

          (3)  the Company or any Guarantor has paid or caused to be paid all
     sums payable by it under this Indenture; and

          (4)  the Company has delivered irrevocable instructions to the Trustee
     under this Indenture to apply the deposited money toward the payment of the
     Notes at maturity or on the redemption date, as the case may be.

In addition, the Company must deliver an Officers' Certificate and an Opinion of
Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied.

     Notwithstanding the satisfaction and discharge of this Indenture, if money
has been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will
survive. In addition, nothing in this Section 11.01 will be deemed to discharge
those provisions of Section 7.07 hereof, that, by their terms, survive the
satisfaction and discharge of this Indenture.

Section 11.02  APPLICATION OF TRUST MONEY.

     Subject to the provisions of Section 8.06 hereof, all money deposited with
the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied
by it, in accordance with the provisions of the Notes 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 (and premium and Liquidated Damages, if any)
and

                                       86
<Page>

interest for whose payment such money has been deposited with the Trustee; but
such money need not be segregated from other funds except to the extent required
by law.

     If the Trustee or Paying Agent is unable to apply any money or Government
Securities in accordance with Section 11.01 hereof 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 and any Guarantor's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 11.01 hereof; PROVIDED that if the Company has made any payment of
principal of, premium or Liquidated Damages, if any, or interest on, any Notes
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Notes to receive such payment from the
money or Government Securities held by the Trustee or Paying Agent.

[INSERT THE GLOBAL NOTE LEGEND, IF APPLICABLE PURSUANT TO THE PROVISIONS OF THE
INDENTURE]

[INSERT THE PRIVATE PLACEMENT LEGEND, IF APPLICABLE PURSUANT TO THE PROVISIONS
OF THE INDENTURE]

     Capitalized terms used herein have the meanings assigned to them in the
Indenture referred to below unless otherwise indicated.

          (1)  INTEREST. iPCS Escrow Company, a Delaware corporation (the
     "Company"), promises to pay interest on the principal amount of this Note
     at 11 1/2% per annum from ________________, 20__ until maturity and shall
     pay the Liquidated Damages, if any, payable pursuant to Section 6 of the
     Registration Rights Agreement referred to below. The Company will pay
     interest and Liquidated Damages, if any, semi-annually in arrears on May 1
     and November 1 of each year, or if any such day is not a Business Day, on
     the next succeeding Business Day (each, an "Interest Payment Date").
     Interest on the Notes will accrue from the most recent date to which
     interest has been paid or, if no interest has been paid, from the date of
     issuance; PROVIDED that if there is no existing Default in the payment of
     interest, and if this Note is authenticated between a record date referred
     to on the face hereof and the next succeeding Interest Payment Date,
     interest shall accrue from such next succeeding Interest Payment Date;
     PROVIDED FURTHER that the first Interest Payment Date shall be
     _____________, 20__. The Company will pay interest (including post-petition
     interest in any proceeding under any Bankruptcy Law) on overdue principal
     and premium, if any, from time to time on demand at a rate that is 1% per
     annum in excess of the rate then in effect to the extent lawful; it will
     pay interest (including post-petition interest in any proceeding under any
     Bankruptcy Law) on overdue installments of interest and Liquidated Damages,
     if any, (without regard to any applicable grace periods) from time to time
     on demand at the same rate to the extent lawful. Interest will be computed
     on the basis of a 360-day year of twelve 30-day months.

          (2)  METHOD OF PAYMENT. The Company will pay interest on the Notes
     (except defaulted interest) and Liquidated Damages, if any, to the Persons
     who are registered Holders of Notes at the close of business on the April
     15 or October 15 next preceding the Interest Payment Date, even if such
     Notes are canceled after such record date and on or before such Interest
     Payment Date, except as provided in Section 2.12 of the Indenture with
     respect to defaulted interest. The Notes will be payable as to principal,
     premium and Liquidated Damages, if any, and interest at the office or
     agency of the Company maintained for such purpose within or without the
     City and State of New York, or, at the option of the Company, payment of
     interest and Liquidated Damages, if any, may be made by check mailed to the
     Holders at their addresses set forth in the register of Holders; PROVIDED
     that payment by wire transfer of immediately available funds will be
     required with respect to principal of and interest, premium and Liquidated
     Damages, if any, on, all Global Notes and all other Notes the Holders of
     which will have provided wire transfer instructions to the Company or the
     Paying Agent. Such payment

                                       A-2
<Page>

     will be in such coin or currency of the United States of America as at the
     time of payment is legal tender for payment of public and private debts.

          (3)  PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National
     Association, the Trustee under the Indenture, will act as Paying Agent and
     Registrar. The Company may change any Paying Agent or Registrar without
     notice to any Holder. The Company or any of its Subsidiaries may act in any
     such capacity.

          (4)  INDENTURE. The Company issued the Notes under an Indenture dated
     as of April 30, 2004 (the "Indenture") among the Company, the Guarantors
     and the Trustee. The terms of the Notes include those stated in the
     Indenture and those made part of the Indenture by reference to the TIA. The
     Notes are subject to all such terms, and Holders are referred to the
     Indenture and such Act for a statement of such terms. To the extent any
     provision of this Note conflicts with the express provisions of the
     Indenture, the provisions of the Indenture shall govern and be controlling.
     The Notes are unsecured obligations of the Company. The Indenture does not
     limit the aggregate principal amount of Notes that may be issued
     thereunder.

          (5)  OPTIONAL REDEMPTION.

     (a)  Except as set forth in subparagraph (b) of this Paragraph 5, the
Company will not have the option to redeem the Notes prior to May 1, 2008. On or
after May 1, 2008, the Company will have the option to redeem all or a part of
the Notes upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest and Liquidated Damages, if any, on the Notes

     Unless the Company defaults in the payment of the redemption price,
interest will cease to accrue on the Notes or portions thereof called for
redemption on the applicable redemption date.

     (b)  Notwithstanding the provisions of subparagraph (a) of this Paragraph
5, at any time prior to May 1, 2008, the Company may on any one or more
occasions redeem up to 35% of the aggregate principal amount of Notes issued
under the Indenture with the net cash proceeds of a sale of Equity Interests
(other than Disqualified Stock) of the Company or a contribution of the
Company's common equity capital at a redemption price equal to 111.500% of the
aggregate principal amount thereof, plus accrued and unpaid interest and
Liquidated Damages, if any to the redemption date; PROVIDED that at least 65% in
aggregate principal amount of the Notes originally issued under the Indenture

outstanding immediately after the occurrence of such redemption and that such
redemption occurs within 45 days of the date of the closing of such sale of
Equity Interests or contribution.

          (6)  MANDATORY REDEMPTION.

               (a)  Except as set forth in subparagraph (b) below, the Company
     is not required to make mandatory redemption or sinking fund payments with
     respect to the Notes.

               (b)  In accordance with the terms and conditions of the Escrow
     Agreement, and using the Deposit, iPCS Escrow Company shall redeem all and
     not less than all of the Initial Notes on (i) August 31, 2004, if the
     Merger has not occurred prior to August 28, 2004, or (ii) such earlier date
     as iPCS Escrow Company shall elect (the "Special Mandatory Redemption
     Date"), in either case, at a redemption price equal to 100% of the
     aggregate principal amount of the Notes, plus accrued and unpaid interest
     thereon through but not including the Special Mandatory Redemption Date. If
     the Merger has not occurred prior to August 28, 2004, the Special Mandatory
     Redemption Date is August 31, 2004. Upon the closing of the merger on or
     before the Special Mandatory Redemption Date, the foregoing provisions of
     this subparagraph (b) shall be null and void. The Special Mandatory
     Redemption Date shall be no more than two Business Days after the date on
     which the parties to the Escrow Agreement decide to terminate the Escrow
     Agreement.

          (7)  REPURCHASE AT THE OPTION OF THE HOLDER.

               (a)  If there is a Change of Control, the Company will be
     required to make an offer (a "Change of Control Offer") to each Holder to
     repurchase all or any part (equal to $1,000 or an integral multiple
     thereof) of each Holder's Notes at a purchase price in cash equal to 101%
     of the aggregate principal amount thereof plus accrued and unpaid interest
     and Liquidated Damages, if any, thereon to the date of purchase, subject to
     the rights of Holders on the relevant record date to receive interest due
     on the relevant interest payment date (the "Change of Control Payment").
     Within ten days following any Change of Control, the Company will mail a
     notice to each Holder setting forth the procedures governing the Change of
     Control Offer as required by the Indenture.

               (b)  If the Company or a Restricted Subsidiary of the Company
     consummates any Asset Sales, within 30 days of each date on which the
     aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will
     commence an offer to all Holders of Notes and all holders of other
     Indebtedness that is pari passu with the Notes containing provisions
     similar to those set forth in the Indenture with respect to offers to
     purchase or redeem with the proceeds of sales of assets (an "Asset Sale
     Offer") pursuant to Section 3.09 of the Indenture to purchase the maximum
     principal amount of Notes (including any Additional Notes) and such other
     pari passu Indebtedness that may be purchased out of the Excess Proceeds at
     an offer price in cash in an amount equal to 100% of the principal amount
     thereof plus accrued and unpaid interest and Liquidated Damages, if any,
     thereon to the date of purchase, in accordance with the procedures set
     forth in the Indenture. To the extent that the aggregate amount of Notes
     (including any

                                       A-4
<Page>

     Additional Notes) and other pari passu Indebtedness tendered pursuant to an
     Asset Sale Offer is less than the Excess Proceeds, the Company (or such
     Restricted Subsidiary) may use such deficiency for any purpose not
     otherwise prohibited by the Indenture. If the aggregate principal amount of
     Notes and other pari passu Indebtedness tendered into such Asset Sale Offer
     exceeds the amount of Excess Proceeds, the Trustee shall select the Notes
     and such other pari passu Indebtedness to be purchased on a pro rata basis.
     Holders of Notes that are the subject of an offer to purchase will receive
     an Asset Sale Offer from the Company prior to any related purchase date and
     may elect to have such Notes purchased by completing the form entitled
     "Option of Holder to Elect Purchase" attached to the Notes.

          (8)  NOTICE OF REDEMPTION. Notice of redemption will be mailed at
     least 30 days but not more than 60 days before the redemption date to each
     Holder whose Notes are to be redeemed at its registered address, except
     that redemption notices may be mailed more than 60 days prior to a
     redemption date if the notice is issued in connection with a defeasance of
     the Notes or a satisfaction or discharge of the Indenture. Notes in
     denominations larger than $1,000 may be redeemed in part but only in whole
     multiples of $1,000, unless all of the Notes held by a Holder are to be
     redeemed.

          (9)  DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
     form without coupons in denominations of $1,000 and integral multiples of
     $1,000. The transfer of Notes may be registered and Notes may be exchanged
     as provided in the Indenture. The Registrar and the Trustee may require a
     Holder, among other things, to furnish appropriate endorsements and
     transfer documents and the Company may require a Holder to pay any taxes
     and fees required by law or permitted by the Indenture. The Company need
     not exchange or register the transfer of any Note or portion of a Note
     selected for redemption, except for the unredeemed portion of any Note
     being redeemed in part. Also, the Company need not exchange or register the
     transfer of any Notes for a period of 15 days before a selection of Notes
     to be redeemed or during the period between a record date and the
     corresponding Interest Payment Date.

          (10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be
     treated as its owner for all purposes.

          (11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions,
     the Indenture or the Notes or the Guarantees may be amended or supplemented
     with the consent of the Holders of at least a majority in aggregate
     principal amount of the then outstanding Notes including Additional Notes,
     if any, voting as a single class, and any existing Default or Event or
     Default or compliance with any provision of the Indenture or the Notes or
     the Guarantees may be waived with the consent of the Holders of a majority
     in aggregate principal amount of the then outstanding Notes including
     Additional Notes, if any, voting as a single class. Without the consent of
     any Holder of a Note, the Indenture or the Notes or the Guarantees may be
     amended or supplemented to cure any ambiguity, defect or inconsistency, to
     provide for uncertificated Notes in addition to or in place of certificated
     Notes, to provide for the assumption of the Company's or a Guarantor's
     obligations to Holders of the Notes and Guarantees in case of a merger or
     consolidation, to make any change that would provide any additional rights
     or benefits to

                                       A-5
<Page>

     the Holders of the Notes or that does not adversely affect the legal rights
     under the Indenture of any such Holder, to comply with the requirements of
     the SEC in order to effect or maintain the qualification of the Indenture
     under the TIA, to conform the text of the Indenture or the Notes to any
     provision of the "Description of Notes" section of the Company's Offering
     Circular dated April 22, 2004, relating to the initial offering of the
     Notes, to the extent that such provision in that "Description of Notes" was
     intended to be a verbatim recitation of a provision of the Indenture, the
     Notes or the Guarantees; to provide for the issuance of Additional Notes in
     accordance with the limitations set forth in the Indenture; or to allow any
     Guarantor to execute a supplemental indenture to the Indenture and/or a
     Guarantee with respect to the Notes.

          (12) DEFAULTS AND REMEDIES. Events of Default include: (i) default for
     30 days in the payment when due of interest on, or Liquidated Damages, if
     any, with respect to the Notes; (ii) default in the payment when due (at
     maturity, upon redemption or otherwise) of the principal of, or premium, if
     any, on, the Notes, (iii) failure by the Company or any of its Restricted
     Subsidiaries to comply with Section 4.07, 4.09, 4.10, 4.15 or 5.01 of the
     Indenture; (iv) failure by the Company or any of its Restricted
     Subsidiaries for 60 days after notice to the Company by the Trustee or the
     Holders of at least 25% in aggregate principal amount of the Notes
     including Additional Notes, if any, then outstanding voting as a single
     class to comply with any of the other agreements in the Indenture or the
     Notes; (v) default under any mortgage, indenture or instrument under which
     there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Company or any of its Restricted
     Subsidiaries (or the payment of which is guaranteed by the Company or any
     of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now
     exists, or is created after the date of the Indenture, if that default: (a)
     is caused by a failure to pay principal of, or interest or premium, if any,
     on, such Indebtedness prior to the expiration of the grace period provided
     in such Indebtedness on the date of such default (a "Payment Default") or
     (b) results in the acceleration of such Indebtedness prior to its express
     maturity, and, in each case, the principal amount of any such Indebtedness,
     together with the principal amount of any other such Indebtedness under
     which there has been a Payment Default or the maturity of which has been so
     accelerated, aggregates $7.5 million or more; or; (vi) certain final
     judgments for the payment of money that remain undischarged for a period of
     60 days; (vii) failure of the Escrow Agreement, at any time to be in full
     force and effect (unless the Deposit is released by the Escrow Agent in
     accordance with the terms of the Escrow Agreement) or any contest by the
     Company or any of its Subsidiaries of the validity or enforceability of the
     Escrow Agreement; (viii) failure by iPCS Escrow Company to redeem the notes
     pursuant to the provisions of the Escrow Agreement; (ix) certain events of
     bankruptcy or insolvency with respect to the Company or any of its
     Restricted Subsidiaries that is a Significant Subsidiary or any group of
     Restricted Subsidiaries that, taken together, would constitute a
     Significant Subsidiary; and (x) except as permitted by the Indenture, any
     Guarantee is held in any judicial proceeding to be unenforceable or invalid
     or ceases for any reason to be in full force and effect or any Guarantor or
     any Person acting on its behalf denies or disaffirms its obligations under
     such Guarantor's Guarantee. If any Event of Default occurs and is
     continuing, the Trustee or the Holders of at least 25% in aggregate
     principal amount of the then outstanding Notes may declare all the Notes to
     be due and payable immediately.

                                       A-6
<Page>

     Notwithstanding the foregoing, in the case of an Event of Default arising
     from certain events of bankruptcy or insolvency, all outstanding Notes will
     become due and payable immediately without further action or notice.
     Holders may not enforce the Indenture or the Notes except as provided in
     the Indenture. Subject to certain limitations, Holders of a majority in
     aggregate principal amount of the then outstanding Notes may direct the
     Trustee in its exercise of any trust or power. The Trustee may withhold
     from Holders of the Notes notice of any continuing Default or Event of
     Default (except a Default or Event of Default relating to the payment of
     principal or interest or premium or Liquidated Damages, if any,) if it
     determines that withholding notice is in their interest. The Holders of a
     majority in aggregate principal amount of the then outstanding Notes by
     notice to the Trustee may, on behalf of the Holders of all of the Notes,
     rescind an acceleration or waive any existing Default or Event of Default
     and its consequences under the Indenture except a continuing Default or
     Event of Default in the payment of interest or premium or Liquidated
     Damages, if any, on, or the principal of, the Notes. The Company is
     required to deliver to the Trustee annually a statement regarding
     compliance with the Indenture, and the Company is required, upon becoming
     aware of any Default or Event of Default, to deliver to the Trustee a
     statement specifying such Default or Event of Default.

          (13) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or
     any other capacity, may make loans to, accept deposits from, and perform
     services for the Company or its Affiliates, and may otherwise deal with the
     Company or its Affiliates, as if it were not the Trustee.

          (14) NO RECOURSE AGAINST OTHERS. A director, officer, employee,
     incorporator or stockholder of the Company or any Guarantors, as such, will
     not have any liability for any obligations of the Company or the Guarantors
     under the Notes, the Guarantees or the Indenture or for any claim based on,
     in respect of, or by reason of, such obligations or their creation. Each
     Holder by accepting a Note waives and releases all such liability. The
     waiver and release are part of the consideration for the issuance of the
     Notes. The waiver may not be effective to waive liabilities under the
     federal securities laws.

          (15) AUTHENTICATION. This Note will not be valid until authenticated
     by the manual signature of the Trustee or an authenticating agent.

          (16) ABBREVIATIONS. Customary abbreviations may be used in the name of
     a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
     tenants by the entireties), JT TEN (= joint tenants with right of
     survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
     (= Uniform Gifts to Minors Act).

          (17) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
     RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders
     of Notes under the Indenture, Holders of Restricted Global Notes and
     Restricted Definitive Notes will have all the rights set forth in the
     Registration Rights Agreement dated as of April 30, 2004, among the
     Company, the Guarantor and the other parties named on the signature pages
     thereof, as such agreement may be amended, modified or supplemented from
     time to time and, with respect to any Additional Notes, Holders of
     Restricted Global

                                       A-7
<Page>

     Notes and Restricted Definitive Notes will have the rights set forth in one
     or more registration rights agreements, if any, among the Company, the
     Guarantors and the other parties thereto, as such agreement(s) may be
     amended, modified or supplemented from time to time, relating to rights
     given by the Company to the purchasers of Additional Notes to register such
     Additional Notes under the Securities Act (collectively, the "Registration
     Rights Agreement").

          (18) 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 Notes, and the Trustee may use
     CUSIP numbers in notices of redemption as a convenience to Holders. No
     representation is made as to the accuracy of such numbers either as printed
     on the Notes or as contained in any notice of redemption, and reliance may
     be placed only on the other identification numbers placed thereon.

          (19) GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL
     GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THIS NOTE AND THE GUARANTEES
     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.

     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.

Credit Suisse First Boston LLC
Bear, Stearns & Co. Inc.
c/o Credit Suisse First Boston LLC
   Eleven Madison Avenue
   New York, New York 10010-3629

Dear Ladies and Gentlemen:

     iPCS Escrow Company, a Delaware corporation (the "Escrow Company") and a
wholly owned indirect subsidiary of iPCS, Inc., a Delaware corporation (the
"Company"), proposes to issue and sell to Credit Suisse First Boston LLC and
Bear, Stearns & Co. Inc. (collectively, the "Initial Purchasers"), upon the
terms set forth in a purchase agreement dated April , 2004 (the "Purchase
Agreement"), $165,000,000 aggregate principal amount of its 11 1/2% Senior Notes
due 2012 (the "Initial Securities"). The Initial Securities will be issued
pursuant to an Indenture, dated as of April 30, 2004 (the "Indenture") between
the Escrow Company and U.S. Bank National Association, as trustee (the
"Trustee").

     The issuance and sale of the Initial Securities is part of a series of
transactions designed to reorganize the ownership and capital structure of the
Company, such transactions being referred to as the "Reorganization". As part of
the consummation of the Reorganization, the Escrow Company will merge with and
into iPCS Escrow Holding

<Page>

Company, a Delaware corporation, which will in turn, merge with and into the
Company, with the Company being the surviving entity (the "Merger").

     Upon consummation of the Merger, the Company will succeed to the
obligations of the Escrow Company under the Indenture and the Initial Securities
and the Company's obligations under this Agreement will become operative.
Notwithstanding the foregoing, in the event of a Special Mandatory Redemption
(as defined in the Indenture), the Company's obligations under this Agreement
will terminate. In addition, upon consummation of the Merger, the Initial
Securities will become fully and unconditionally guaranteed (the "Guarantees")
as to payment of principal and interest and premium and liquidated damages, if
any, on an unsecured senior basis, jointly and severally, by all of the
Company's subsidiaries (after giving effect to the Reorganization) listed on
Schedule A hereto (collectively, the "Guarantors" and, together with the
Company, the "Issuers").

     As an inducement to the Initial Purchasers, the Issuers agree with the
Initial Purchasers, for the benefit of the holders of the Initial Securities
(including, without limitation, the Initial Purchasers), the Exchange Securities
(as defined below) and the Private Exchange Securities (as defined below)
(collectively the "Holders"), as follows:

     1.   REGISTERED EXCHANGE OFFER. The Issuers shall, at their own cost,
prepare and, on or prior to the later to occur of (i) 120 days after (or if the
120th day is not a business day, the first business day thereafter) the date of
original issue of the Initial Securities (the "Issue Date") and (ii) 45 days
after (or if the 45th day is not a business day, the first business day
thereafter) the date of the confirmation of the Plan of Reorganization (the
"Confirmation Date"), file with the Securities and Exchange Commission (the
"Commission") a registration statement (the "Exchange Offer Registration
Statement") on an appropriate form under the Securities Act of 1933, as amended
(the "Securities Act"), with respect to a proposed offer (the "Registered
Exchange Offer") to the Holders of Transfer Restricted Securities (as defined in
Section 6 hereof), who are not prohibited by any law or policy of the Commission
from participating in the Registered Exchange Offer, to issue and deliver to
such Holders, in exchange for the Initial Securities, a like aggregate principal
amount of debt securities (the "Exchange Securities") of the Company issued
under the Indenture and identical in all material respects to the Initial
Securities (except for the transfer restrictions relating to the Initial
Securities and the provisions relating to the matters described in Section 6
hereof) that would be registered under the Securities Act. The Issuers shall use
their commercially reasonable efforts to cause such Exchange Offer Registration
Statement to become effective under the Securities Act on or prior to the later
to occur of (i) 210 days (or if the 210th day is not a business day, the first
business day thereafter) after the Issue Date and (ii) 135 days (or if the 135th
day is not a business day, the first business day thereafter) after the
Confirmation Date and shall keep the Exchange Offer Registration Statement
effective for not less than 30 days (or longer, if required by applicable law)
after the date notice of the Registered Exchange

                                        2
<Page>

Offer is mailed to the Holders (such period being called the "Exchange Offer
Registration Period").

     If the Issuers effect the Registered Exchange Offer, the Issuers will be
entitled to close the Registered Exchange Offer 30 days after the commencement
thereof provided that the Issuers have accepted all the Initial Securities
theretofore validly tendered in accordance with the terms of the Registered
Exchange Offer.

     Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Issuers shall promptly commence the Registered
Exchange Offer, it being the objective of such Registered Exchange Offer to
enable each Holder of Transfer Restricted Securities (as defined in Section 6
hereof) electing to exchange the Initial Securities for Exchange Securities
(assuming that such Holder is not an affiliate of the Issuers within the meaning
of the Securities Act, acquires the Exchange Securities in the ordinary course
of such Holder's business and has no arrangements with any person to participate
in the distribution of the Exchange Securities and is not prohibited by any law
or policy of the Commission from participating in the Registered Exchange Offer)
to trade such Exchange Securities from and after their receipt without any
limitations or restrictions under the Securities Act and without material
restrictions under the securities laws of the several states of the United
States.

     The Issuers acknowledge that, pursuant to current interpretations by the
Commission's staff of Section 5 of the Securities Act, in the absence of an
applicable exemption therefrom, (i) each Holder which is a broker-dealer
electing to exchange Securities, acquired for its own account as a result of
market making activities or other trading activities, for Exchange Securities
(an "Exchanging Dealer"), is required to deliver a prospectus containing the
information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in
the "Exchange Offer Procedures" section and the "Purpose of the Exchange Offer"
section, and (c) Annex C hereto in the "Plan of Distribution" section of such
prospectus in connection with a sale of any such Exchange Securities received by
such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an
Initial Purchaser that elects to sell Exchange Securities acquired in exchange
for Securities constituting any portion of an unsold allotment is required to
deliver a prospectus containing the information required by Items 507 or 508 of
Regulation S-K under the Securities Act, as applicable, in connection with such
sale.

     The Issuers shall use their commercially reasonable best efforts to keep
the Exchange Offer Registration Statement effective and to amend and supplement
the prospectus contained therein, in order to permit such prospectus to be
lawfully delivered by all persons subject to the prospectus delivery
requirements of the Securities Act for such period of time as such persons must
comply with such requirements in order to resell the Exchange Securities;
provided, however, that (i) in the case where such prospectus and any amendment
or supplement thereto must be delivered by an

                                        3
<Page>

Exchanging Dealer or an Initial Purchaser, such period shall be the lesser of
180 days and the date on which all Exchanging Dealers and the Initial Purchasers
have sold all Exchange Securities held by them (unless such period is extended
pursuant to Section 3(j) below) and (ii) the Issuers shall make such prospectus
and any amendment or supplement thereto, available to any broker-dealer for use
in connection with any resale of any Exchange Securities for a period of not
less than 90 days after the consummation of the Registered Exchange Offer.

     If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Issuers, simultaneously with the delivery of the Exchange
Securities pursuant to the Registered Exchange Offer, shall issue and deliver to
such Initial Purchaser upon the written request of such Initial Purchaser, in
exchange (the "Private Exchange") for the Initial Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company
issued under the Indenture and identical in all material respects (including the
existence of restrictions on transfer under the Securities Act and the
securities laws of the several states of the United States, but excluding
provisions relating to the matters described in Section 6 hereof) to the Initial
Securities (the "Private Exchange Securities"). The Initial Securities, the
Exchange Securities and the Private Exchange Securities are herein collectively
called the "Securities".

     In connection with the Registered Exchange Offer, the Issuers shall:

          (a) mail to each Holder a copy of the prospectus forming part of the
     Exchange Offer Registration Statement, together with an appropriate letter
     of transmittal and related documents;

          (b) keep the Registered Exchange Offer open for not less than 30 days
     (or longer, if required by applicable law) after the date notice thereof is
     mailed to the Holders;

          (c) utilize the services of a depositary for the Registered Exchange
     Offer with an address in the Borough of Manhattan, The City of New York,
     which may be the Trustee or an affiliate of the Trustee;

          (d) permit Holders to withdraw tendered Securities at any time prior
     to the close of business, New York time, on the last business day on which
     the Registered Exchange Offer shall remain open; and

          (e) otherwise comply with all applicable laws.

                                        4
<Page>

     As soon as practicable after the close of the Registered Exchange Offer or
the Private Exchange, as the case may be, the Issuers shall:

          (x) accept for exchange all the Securities validly tendered and not
     withdrawn pursuant to the Registered Exchange Offer and the Private
     Exchange;

          (y) deliver to the Trustee for cancellation all the Initial Securities
     so accepted for exchange; and

          (z) cause the Trustee to authenticate and deliver promptly to each
     Holder of the Initial Securities, Exchange Securities or Private Exchange
     Securities, as the case may be, equal in principal amount to the Initial
     Securities of such Holder so accepted for exchange.

     The Indenture will provide that the Exchange Securities will not be subject
to the transfer restrictions set forth in the Indenture and that all the
Securities will vote and consent together on all matters as one class and that
none of the Securities will have the right to vote or consent as a class
separate from one another on any matter.

     Interest on each Exchange Security and Private Exchange Security issued
pursuant to the Registered Exchange Offer and in the Private Exchange will
accrue from the last interest payment date on which interest was paid on the
Initial Securities surrendered in exchange therefor or, if no interest has been
paid on the Initial Securities, from the date of original issue of the Initial
Securities.

     Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Issuers that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities received by such Holder
will be acquired in the ordinary course of business, (ii) such Holder will have
no arrangements or understanding with any person to participate in the
distribution of the Securities or the Exchange Securities within the meaning of
the Securities Act, (iii) such Holder is not an "affiliate," as defined in Rule
405 under the Securities Act, of the Issuers or if it is an affiliate, such
Holder will comply with the registration and prospectus delivery requirements of
the Securities Act to the extent applicable, (iv) if such Holder is not a
broker-dealer, that it is not engaged in, and does not intend to engage in, the
distribution of the Exchange Securities and (v) if such Holder is a
broker-dealer, that it will receive Exchange Securities for its own account in
exchange for Initial Securities that were acquired as a result of market-making
activities or other trading activities and that it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Securities.

                                        5
<Page>

     Notwithstanding any other provisions hereof, the Issuers will ensure that
(i) any Exchange Offer Registration Statement and any amendment thereto and any
prospectus forming part thereof and any supplement thereto complies in all
material respects with the Securities Act and the rules and regulations
thereunder, (ii) any Exchange Offer Registration Statement and any amendment
thereto does not, when it becomes effective, contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading and (iii) any prospectus
forming part of any Exchange Offer Registration Statement, and any supplement to
such prospectus, does not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

     2.   SHELF REGISTRATION. If, (i) the Issuers are not required to file the
Exchange Offer Registration Statement, as contemplated by Section 1 hereof, (ii)
because of any change in law or in applicable interpretations thereof by the
staff of the Commission, the Issuers are not permitted to effect a Registered
Exchange Offer, as contemplated by Section 1 hereof, (iii) the Registered
Exchange Offer is not consummated by the 31st day after the date that is the
later of (a) November 27, 2004 and (b) 136th day from the Confirmation Date, or
(iv) if, with respect to each of the following, the Holder notifies the Issuers
prior to the 20th Business Day following the consummation of the Registered
Exchange Offer that: (a) such Holder is prohibited by law or policy of the
Commission from participating in the Registered Exchange Offer, (b) such Holder
may not resell the Exchange Securities acquired by it in the Registered Exchange
Offer to the public without delivering a prospectus and the prospectus contained
in the Exchange Offer Registration Statement is not appropriate or available for
such resales or (c) such Holder is a broker-dealer and owns Securities acquired
directly from the Issuers or an affiliate of the Issuers, the Issuers shall take
the following actions:

          (a) The Issuers shall use all commercially reasonable efforts, at
     their cost, on or prior to 30 days after so required or requested pursuant
     to this Section 2) file with the Commission a registration statement (the
     "Shelf Registration Statement" and, together with the Exchange Offer
     Registration Statement, a "Registration Statement") on an appropriate form
     under the Securities Act relating to the offer and sale of the Transfer
     Restricted Securities (as defined in Section 6 hereof) by the Holders
     thereof from time to time in accordance with the methods of distribution
     set forth in the Shelf Registration Statement and Rule 415 under the
     Securities Act (hereinafter, the "Shelf Registration"); provided, however,
     that no Holder (other than an Initial Purchaser) shall be entitled to have
     the Securities held by it covered by such Shelf Registration Statement
     unless such Holder agrees in writing to be bound by all the provisions of
     this Agreement applicable to such Holder. The Issuers shall use their
     commercially reasonable efforts to cause such

                                        6
<Page>

     Shelf Registration Statement to become effective under the Securities Act
     within 90 days (or if the 90th day is not a business day, the first
     business day thereafter) after so required or requested to file such Shelf
     Registration Statement pursuant to this Section 2.

          (b) The Issuers shall use their commercially reasonable efforts to
     keep the Shelf Registration Statement continuously effective in order to
     permit the prospectus included therein to be lawfully delivered by the
     Holders of the relevant Securities, for a period of two years (or for such
     longer period if extended pursuant to Section 3(j) below) from the date of
     its effectiveness or such shorter period that will terminate when all the
     Securities covered by the Shelf Registration Statement (i) have been sold
     pursuant thereto or (ii) are no longer restricted securities (as defined in
     Rule 144 under the Securities Act, or any successor rule thereof). The
     Issuers shall be deemed not to have used their commercially reasonable
     efforts to keep the Shelf Registration Statement effective during the
     requisite period if it voluntarily takes any action that would result in
     Holders of Securities covered thereby not being able to offer and sell such
     Securities during that period, unless such action is required by applicable
     law.

          (c) Notwithstanding any other provisions of this Agreement to the
     contrary, the Issuers shall cause the Shelf Registration Statement and the
     related prospectus and any amendment or supplement thereto, as of the
     effective date of the Shelf Registration Statement, amendment or
     supplement, (i) to comply in all material respects with the applicable
     requirements of the Securities Act and the rules and regulations of the
     Commission and (ii) not to contain any untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     in order to make the statements therein, in light of the circumstances
     under which they were made, not misleading.

     3.   REGISTRATION PROCEDURES. In connection with any Shelf Registration
contemplated by Section 2 hereof and, to the extent applicable, any Registered
Exchange Offer contemplated by Section 1 hereof, the following provisions shall
apply:

          (a) The Issuers shall (i) furnish to each Initial Purchaser, prior to
     the filing thereof with the Commission, a copy of the Registration
     Statement and each amendment thereof and each supplement, if any, to the
     prospectus included therein and, in the event that an Initial Purchaser
     (with respect to any portion of an unsold allotment from the original
     offering) is participating in the Registered Exchange Offer or the Shelf
     Registration Statement, the Issuers shall use their commercially reasonable
     efforts to reflect in each such document, when so filed with the
     Commission, such comments as such Initial Purchaser reasonably may propose;
     (ii) include the information set forth in Annex A hereto on the cover, in

                                        7
<Page>

     Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose
     of the Exchange Offer" section and in Annex C hereto in the "Plan of
     Distribution" section of the prospectus forming a part of the Exchange
     Offer Registration Statement and include the information set forth in Annex
     D hereto in the Letter of Transmittal delivered pursuant to the Registered
     Exchange Offer; (iii) if requested by an Initial Purchaser, include the
     information required by Items 507 or 508 of Regulation S-K under the
     Securities Act, as applicable, in the prospectus forming a part of the
     Exchange Offer Registration Statement; (iv) include within the prospectus
     contained in the Exchange Offer Registration Statement a section entitled
     "Plan of Distribution," reasonably acceptable to the Initial Purchasers,
     which shall contain a summary statement of the positions taken or policies
     made by the staff of the Commission with respect to the potential
     "underwriter" status of any broker-dealer that is the beneficial owner (as
     defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended
     (the "Exchange Act")) of Exchange Securities received by such broker-dealer
     in the Registered Exchange Offer (a "Participating Broker-Dealer"), whether
     such positions or policies have been publicly disseminated by the staff of
     the Commission or such positions or policies, in the reasonable judgment of
     the Initial Purchasers based upon the written advice of counsel (which may
     be in-house counsel), represent the prevailing views of the staff of the
     Commission; and (v) in the case of a Shelf Registration Statement, include
     the names of the Holders, who propose to sell Securities pursuant to the
     Shelf Registration Statement, as selling securityholders.

          (b) The Issuers shall give written notice to the Initial Purchasers,
     the Holders of the Securities and any Participating Broker-Dealer from whom
     the Issuers have received prior written notice that it will be a
     Participating Broker-Dealer in the Registered Exchange Offer (which notice
     pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction
     to suspend the use of the prospectus until the requisite changes have been
     made):

                 (i)    when the Registration Statement or any amendment thereto
          has been filed with the Commission and when the Registration Statement
          or any post-effective amendment thereto has become effective;

                 (ii)   of any request by the Commission for amendments or
          supplements to the Registration Statement or the prospectus included
          therein or for additional information;

                 (iii)  of the issuance by the Commission of any stop order
          suspending the effectiveness of the Registration Statement or the
          initiation of any proceedings for that purpose;

                                        8
<Page>

                 (iv)   of the receipt by the Issuers or their legal counsel of
          any notification with respect to the suspension of the qualification
          of the Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose; and

                 (v)    of the happening of any event that requires the Issuers
          to make changes in the Registration Statement or the prospectus in
          order that the Registration Statement or the prospectus do not contain
          an untrue statement of a material fact nor omit to state a material
          fact required to be stated therein or necessary to make the statements
          therein (in the case of the prospectus, in light of the circumstances
          under which they were made) not misleading.

          (c) The Issuers shall make every reasonable effort to obtain the
     withdrawal at the earliest possible time, of any order suspending the
     effectiveness of the Registration Statement.

          (d) The Issuers shall furnish to each Holder of Securities included
     within the coverage of the Shelf Registration, without charge, at least one
     copy of the Shelf Registration Statement and any post-effective amendment
     thereto, including financial statements and schedules, and, if the Holder
     so requests in writing, all exhibits thereto (including those, if any,
     incorporated by reference).

          (e) The Issuers shall deliver to each Exchanging Dealer and each
     Initial Purchaser, and to any other Holder who so requests, without charge,
     at least one copy of the Exchange Offer Registration Statement and any
     post-effective amendment thereto, including financial statements and
     schedules, and, if any Initial Purchaser or any such Holder requests, all
     exhibits thereto (including those incorporated by reference).

          (f) The Issuers shall, during the Shelf Registration Period, deliver
     to each Holder of Securities included within the coverage of the Shelf
     Registration, without charge, as many copies of the prospectus (including
     each preliminary prospectus) included in the Shelf Registration Statement
     and any amendment or supplement thereto as such person may reasonably
     request. The Issuers consent, subject to the provisions of this Agreement,
     to the use of the prospectus or any amendment or supplement thereto by each
     of the selling Holders of the Securities in connection with the offering
     and sale of the Securities covered by the prospectus, or any amendment or
     supplement thereto, included in the Shelf Registration Statement.

                                        9

          (g) The Issuers shall deliver to each Initial Purchaser, any
     Exchanging Dealer, any Participating Broker-Dealer and such other persons
     required to deliver a prospectus following the Registered Exchange Offer,
     without charge, as many copies of the final prospectus included in the
     Exchange Offer Registration Statement and any amendment or supplement
     thereto as such persons may reasonably request. The Issuers consent,
     subject to the provisions of this Agreement, to the use of the prospectus
     or any amendment or supplement thereto by any Initial Purchaser, if
     necessary, any Participating Broker-Dealer and such other persons required
     to deliver a prospectus following the Registered Exchange Offer in
     connection with the offering and sale of the Exchange Securities covered by
     the prospectus, or any amendment or supplement thereto, included in such
     Exchange Offer Registration Statement.

          (h) Prior to any public offering of the Securities, pursuant to any
     Registration Statement, the Issuers shall register or qualify or cooperate
     with the Holders of the Securities included therein and their respective
     counsel in connection with the registration or qualification of the
     Securities for offer and sale under the securities or "blue sky" laws of
     such states of the United States as any Holder of the Securities reasonably
     requests in writing and do any and all other acts or things necessary or
     advisable to enable the offer and sale in such jurisdictions of the
     Securities covered by such Registration Statement; provided, however, that
     the Issuers shall not be required to (i) qualify generally to do business
     in any jurisdiction where it is not then so qualified or (ii) take any
     action which would subject it to general service of process or to taxation
     in any jurisdiction where it is not then so subject.

          (i) The Issuers shall cooperate with the Holders of the Securities to
     facilitate the timely preparation and delivery of certificates representing
     the Securities to be sold pursuant to any Registration Statement free of
     any restrictive legends and in such denominations and registered in such
     names as the Holders may request a reasonable period of time prior to sales
     of the Securities pursuant to such Registration Statement.

          (j) Upon the occurrence of any event contemplated by paragraphs (ii)
     through (v) of Section 3(b) above during the period for which the Issuers
     are required to maintain an effective Registration Statement, the Issuers
     shall promptly prepare and file a post-effective amendment to the
     Registration Statement or a supplement to the related prospectus and any
     other required document so that, as thereafter delivered to Holders of the
     Securities or purchasers of Securities, the prospectus will not contain an
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein,
     in light of the circumstances under which they were made,

                                       10
<Page>

     not misleading. If the Issuers notify the Initial Purchasers, the Holders
     of the Securities and any known Participating Broker-Dealer in accordance
     with paragraphs (ii) through (v) of Section 3(b) above to suspend the use
     of the prospectus until the requisite changes to the prospectus have been
     made, then the Initial Purchasers, the Holders of the Securities and any
     such Participating Broker-Dealers shall suspend use of such prospectus, and
     the period of effectiveness of the Shelf Registration Statement provided
     for in Section 2(b) above and the Exchange Offer Registration Statement
     provided for in Section 1 above shall each be extended by the number of
     days from and including the date of the giving of such notice to and
     including the date when the Initial Purchasers, the Holders of the
     Securities and any known Participating Broker-Dealer shall have received
     such amended or supplemented prospectus pursuant to this Section 3(j).

          (k) Not later than the effective date of the applicable Registration
     Statement, the Issuers will provide a CUSIP number for the Initial
     Securities, the Exchange Securities or the Private Exchange Securities, as
     the case may be, and provide the applicable trustee with printed
     certificates for the Initial Securities, the Exchange Securities or the
     Private Exchange Securities, as the case may be, in a form eligible for
     deposit with The Depository Trust Company.

          (l) The Issuers will comply with all rules and regulations of the
     Commission to the extent and so long as they are applicable to the
     Registered Exchange Offer or the Shelf Registration and will make generally
     available to their security holders (or otherwise provide in accordance
     with Section 11(a) of the Securities Act) an earnings statement satisfying
     the provisions of Section 11(a) of the Securities Act, no later than 45
     days after the end of a 12-month period (or 90 days, if such period is a
     fiscal year) beginning with the first month of the Issuers' first fiscal
     quarter commencing after the effective date of the Registration Statement,
     which statement shall cover such 12-month period.

          (m) The Issuers shall cause the Indenture to be qualified under the
     Trust Indenture Act of 1939, as amended, in a timely manner and containing
     such changes, if any, as shall be necessary for such qualification. In the
     event that such qualification would require the appointment of a new
     trustee under the Indenture, the Issuers shall appoint a new trustee
     thereunder pursuant to the applicable provisions of the Indenture.

          (n) The Issuers may require each Holder of Securities to be sold
     pursuant to the Shelf Registration Statement to furnish to the Issuers such
     information regarding the Holder and the distribution of the Securities as
     the Issuers may from time to time reasonably require for inclusion in the
     Shelf Registration Statement, and the Issuers may exclude from such
     registration the Securities of any Holder

                                       11
<Page>

     that unreasonably fails to furnish such information within a reasonable
     time after receiving such request.

          (o) The Issuers shall enter into such customary agreements (including,
     if requested, an underwriting agreement in customary form) and take all
     such other action, if any, as any Holder of the Securities shall reasonably
     request in order to facilitate the disposition of the Securities pursuant
     to any Shelf Registration.

          (p) In the case of any Shelf Registration, the Issuers shall (i) make
     reasonably available for inspection by the Holders of the Securities, any
     underwriter participating in any disposition pursuant to the Shelf
     Registration Statement and any attorney, accountant or other agent retained
     by the Holders of the Securities or any such underwriter all relevant
     financial and other records, pertinent corporate documents and properties
     of the Issuers and (ii) cause the Issuers' officers, directors, employees,
     accountants and auditors to supply all relevant information reasonably
     requested by the Holders of the Securities or any such underwriter,
     attorney, accountant or agent in connection with the Shelf Registration
     Statement, in each case, as shall be reasonably necessary to enable such
     persons, to conduct a reasonable investigation within the meaning of
     Section 11 of the Securities Act; provided, however, that the foregoing
     inspection and information gathering shall be coordinated on behalf of the
     Initial Purchasers by you and on behalf of the other parties, by one
     counsel designated by and on behalf of such other parties as described in
     Section 4 hereof.

          (q) In the case of any Shelf Registration, the Issuers, if requested
     by any Holder of Securities covered thereby, shall cause (i) their counsel
     to deliver an opinion and updates thereof relating to the Securities in
     customary form addressed to such Holders and the managing underwriters, if
     any, thereof and dated, in the case of the initial opinion, the effective
     date of such Shelf Registration Statement (it being agreed that the matters
     to be covered by such opinion shall include, without limitation, the due
     incorporation and good standing of the Issuers; the qualification of the
     Issuers to transact business as foreign corporations; the due
     authorization, execution and delivery of the relevant agreement of the type
     referred to in Section 3(o) hereof; the due authorization, execution,
     authentication and issuance, and the validity and enforceability, of the
     applicable Securities; the absence of material legal or governmental
     proceedings involving the Issuers; the absence of governmental approvals
     required to be obtained in connection with the Shelf Registration
     Statement, the offering and sale of the applicable Securities, or any
     agreement of the type referred to in Section 3(o) hereof; the compliance as
     to form of such Shelf Registration Statement and any documents incorporated
     by reference therein and of the Indenture with the requirements of the
     Securities Act and the Trust Indenture Act, respectively; and, as of the
     date of the opinion and as

                                       12
<Page>

     of the effective date of the Shelf Registration Statement or most recent
     post-effective amendment thereto, as the case may be, the absence from such
     Shelf Registration Statement and the prospectus included therein, as then
     amended or supplemented, and from any documents incorporated by reference
     therein of an untrue statement of a material fact or the omission to state
     therein a material fact required to be stated therein or necessary to make
     the statements therein not misleading (in the case of any such documents,
     in the light of the circumstances existing at the time that such documents
     were filed with the Commission under the Exchange Act); (ii) their officers
     to execute and deliver all customary documents and certificates and updates
     thereof requested by any underwriters of the applicable Securities and
     (iii) their independent public accountants to provide to the selling
     Holders of the applicable Securities and any underwriter therefor a comfort
     letter in customary form and covering matters of the type customarily
     covered in comfort letters in connection with primary underwritten
     offerings, subject to receipt of appropriate documentation as contemplated,
     and only if permitted, by Statement of Auditing Standards No. 72.

          (r) In the case of the Registered Exchange Offer, if requested by any
     Initial Purchaser or any known Participating Broker-Dealer, the Issuers
     shall cause (i) their counsel to deliver to such Initial Purchaser or such
     Participating Broker-Dealer a signed opinion in the form set forth in
     Section 6(c) of the Purchase Agreement with such changes as are customary
     in connection with the preparation of a Registration Statement and (ii)
     their independent public accountants to deliver to such Initial Purchaser
     or such Participating Broker-Dealer a comfort letter, in customary form,
     meeting the requirements as to the substance thereof as set forth in
     Section 6(a) and (f) of the Purchase Agreement, with appropriate date
     changes.

          (s) If a Registered Exchange Offer or a Private Exchange is to be
     consummated, upon delivery of the Initial Securities by Holders to the
     Issuers (or to such other Person as directed by the Issuers) in exchange
     for the Exchange Securities or the Private Exchange Securities, as the case
     may be, the Issuers shall mark, or caused to be marked, on the Initial
     Securities so exchanged that such Initial Securities are being canceled in
     exchange for the Exchange Securities or the Private Exchange Securities, as
     the case may be; in no event shall the Initial Securities be marked as paid
     or otherwise satisfied.

          (t) The Issuers will use their best efforts to (a) if the Initial
     Securities have been rated prior to the initial sale of such Initial
     Securities, confirm such ratings will apply to the Securities covered by a
     Registration Statement, or (b) if the Initial Securities were not
     previously rated, cause the Securities covered by a Registration Statement
     to be rated with the appropriate rating agencies, if so

                                       13
<Page>

     requested by Holders of a majority in aggregate principal amount of
     Securities covered by such Registration Statement, or by the managing
     underwriters, if any.

          (u) In the event that any broker-dealer registered under the Exchange
     Act shall underwrite any Securities or participate as a member of an
     underwriting syndicate or selling group or "assist in the distribution"
     (within the meaning of the Conduct Rules (the "Rules") of the National
     Association of Securities Dealers, Inc. ("NASD")) thereof, whether as a
     Holder of such Securities or as an underwriter, a placement or sales agent
     or a broker or dealer in respect thereof, or otherwise, the Issuers will
     assist such broker-dealer in complying with the requirements of such Rules,
     including, without limitation, by (i) if such Rules, including Rule 2720,
     shall so require, engaging a "qualified independent underwriter" (as
     defined in Rule 2720) to participate in the preparation of the Registration
     Statement relating to such Securities, to exercise usual standards of due
     diligence in respect thereto and, if any portion of the offering
     contemplated by such Registration Statement is an underwritten offering or
     is made through a placement or sales agent, to recommend the yield of such
     Securities, (ii) indemnifying any such qualified independent underwriter to
     the extent of the indemnification of underwriters provided in Section 5
     hereof and (iii) providing such information to such broker-dealer as may be
     required in order for such broker-dealer to comply with the requirements of
     the Rules.

          (v) The Issuers shall use their commercially reasonable efforts to
     take all other steps necessary to effect the registration of the Securities
     covered by a Registration Statement contemplated hereby.

     4.   REGISTRATION EXPENSES. The Issuers shall bear all fees and expenses
incurred in connection with the performance of their obligations under Sections
1 through 3 hereof, whether or not the Registered Exchange Offer or a Shelf
Registration is filed or becomes effective, and, in the event of a Shelf
Registration, shall bear or reimburse the Holders of the Securities covered
thereby who are Initial Purchasers for the reasonable fees and disbursements of
one firm to act as counsel in connection therewith.

     5.   INDEMNIFICATION. (a) The Issuers agree to indemnify and hold harmless
each Holder of the Securities, any Participating Broker-Dealer and each person,
if any, who controls such Holder or such Participating Broker-Dealer within the
meaning of the Securities Act or the Exchange Act (each Holder, any
Participating Broker-Dealer and such controlling persons are referred to
collectively as the "Indemnified Parties") from and against any losses, claims,
damages or liabilities, joint or several, or any actions in respect thereof
(including, but not limited to, any losses, claims, damages, liabilities or
actions relating to purchases and sales of the Securities) to which each
Indemnified Party may become subject under the Securities Act, the Exchange Act
or otherwise, insofar as

                                       14
<Page>

such losses, claims, damages, liabilities or actions arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in a Registration Statement or prospectus or in any amendment or
supplement thereto or in any preliminary prospectus relating to a Shelf
Registration, or arise out of, or are based upon, the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and shall reimburse, as
incurred, the Indemnified Parties for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action in respect thereof; provided, however, that
(i) the Issuers shall not be liable in any such case to the extent that such
loss, claim, damage or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration in reliance
upon and in conformity with written information pertaining to such Holder and
furnished to the Issuers by or on behalf of such Holder specifically for
inclusion therein and (ii) with respect to any untrue statement or omission or
alleged untrue statement or omission made in any preliminary prospectus relating
to a Shelf Registration Statement, the indemnity agreement contained in this
subsection (a) shall not inure to the benefit of any Holder or Participating
Broker-Dealer from whom the person asserting any such losses, claims, damages or
liabilities purchased the Securities concerned, to the extent that a prospectus
relating to such Securities was required to be delivered by such Holder or
Participating Broker-Dealer under the Securities Act in connection with such
purchase and any such loss, claim, damage or liability of such Holder or
Participating Broker-Dealer results from the fact that there was not sent or
given to such person, at or prior to the written confirmation of the sale of
such Securities to such person, a copy of the final prospectus if the Issuers
have previously furnished copies thereof to such Holder or Participating
Broker-Dealer; provided further, however, that this indemnity agreement will be
in addition to any liability which the Issuers may otherwise have to such
Indemnified Party. The Issuers shall also indemnify underwriters, their officers
and directors and each person who controls such underwriters within the meaning
of the Securities Act or the Exchange Act to the same extent as provided above
with respect to the indemnification of the Holders of the Securities if
requested by such Holders.

     (b) Each Holder of the Securities, severally and not jointly, will
indemnify and hold harmless each Issuer and each person, if any, who controls
such Issuer within the meaning of the Securities Act or the Exchange Act from
and against any losses, claims, damages or liabilities or any actions in respect
thereof, to which each Issuer or any such controlling person may become subject
under the Securities Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration, or arise out
of or are based

                                       15
<Page>

upon the omission or alleged omission to state therein a material fact necessary
to make the statements therein not misleading, but in each case only to the
extent that the untrue statement or omission or alleged untrue statement or
omission was made in reliance upon and in conformity with written information
pertaining to such Holder and furnished to the Issuers by or on behalf of such
Holder specifically for inclusion therein; and, subject to the limitation set
forth immediately preceding this clause, shall reimburse, as incurred, the
Issuers for any legal or other expenses reasonably incurred by the Issuers or
any such controlling person in connection with investigating or defending any
loss, claim, damage, liability or action in respect thereof. This indemnity
agreement will be in addition to any liability which such Holder may otherwise
have to the Issuers or any of their controlling persons.

     (c) Promptly after receipt by an indemnified party under this Section 5 of
notice of the commencement of any action or proceeding (including a governmental
investigation), such indemnified party will, if a claim in respect thereof is to
be made against the indemnifying party under this Section 5, notify the
indemnifying party of the commencement thereof; but the failure to notify the
indemnifying party shall not relieve the indemnifying party from any liability
that it may have under subsection (a) or (b) above except to the extent that it
has been materially prejudiced (through the forfeiture of substantive rights or
defenses) by such failure; and provided further that the failure to notify the
indemnifying party shall not relieve it from any liability that it may have to
an indemnified party otherwise than under subsection (a) or (b) above. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof the
indemnifying party will not be liable to such indemnified party under this
Section 5 for any legal or other expenses, other than reasonable costs of
investigation, subsequently incurred by such indemnified party in connection
with the defense thereof. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party unless such settlement (i) includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter
of such action, and (ii) does not include a statement as to or an admission of
fault, culpability or a failure to act by or on behalf of any indemnified party.

     (d) If the indemnification provided for in this Section 5 is unavailable or
insufficient to hold harmless an indemnified party under subsections (a) or (b)
above,

                                       16
<Page>

then each indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of the losses, claims, damages or liabilities
(or actions in respect thereof) referred to in subsection (a) or (b) above (i)
in such proportion as is appropriate to reflect the relative benefits received
by the indemnifying party or parties on the one hand and the indemnified party
on the other from the exchange of the Securities, pursuant to the Registered
Exchange Offer, or (ii) if the allocation provided by the foregoing clause (i)
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the indemnifying party or parties on the one hand and the
indemnified party on the other in connection with the statements or omissions
that resulted in such losses, claims, damages or liabilities (or actions in
respect thereof) as well as any other relevant equitable considerations. The
relative fault of the parties shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Issuers on the one hand or such Holder or such other indemnified
party, as the case may be, on the other, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid by an indemnified party as a result of
the losses, claims, damages or liabilities referred to in the first sentence of
this subsection (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any action or claim which is the subject of this subsection (d).
Notwithstanding any other provision of this Section 5(d), the Holders of the
Securities shall not be required to contribute any amount in excess of the
amount by which the net proceeds received by such Holders from the sale of the
Securities pursuant to a Registration Statement exceeds the amount of damages
which such Holders have otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this paragraph (d),
each person, if any, who controls such indemnified party within the meaning of
the Securities Act or the Exchange Act shall have the same rights to
contribution as such indemnified party and each person, if any, who controls any
Issuer within the meaning of the Securities Act or the Exchange Act shall have
the same rights to contribution as the Issuers.

     (e) The agreements contained in this Section 5 shall survive the sale of
the Securities pursuant to a Registration Statement and shall remain in full
force and effect, regardless of any termination or cancellation of this
Agreement or any investigation made by or on behalf of any indemnified party.

     6.   LIQUIDATED DAMAGES UNDER CERTAIN CIRCUMSTANCES. (a) Liquidated Damages
("Liquidated Damages") with respect to the Initial Securities shall be assessed
as follows

                                       17
<Page>

if any of the following events occur (each such event in clauses (i) through
(iv) below a "Registration Default":

          (i)    If by the later of (a) August 29, 2004 and (b) the 46th day
     from the Confirmation Date, neither the Exchange Offer Registration
     Statement nor a Shelf Registration Statement has been filed with the
     Commission;

          (ii)   If by the later of (a) November 27, 2004 and (b) the 136th day
     from the Confirmation Date, neither the Exchange Offer Registration
     Statement nor a Shelf Registration Statement has been declared effective by
     the Commission;

          (iii)  If by the 31st day after the date that is the later of the
     dates in Section 6(ii) above, the Registered Exchange Offer has not been
     consummated; or

          (iv)   If after the Exchange Offer Registration Statement or the Shelf
     Registration Statement is declared effective (A) such Registration
     Statement thereafter ceases to be effective; or (B) such Registration
     Statement or the related prospectus ceases to be usable (except as
     permitted in paragraph (b)) in connection with resales of Transfer
     Restricted Securities during the periods specified herein because either
     (1) any event occurs as a result of which the related prospectus forming
     part of such Registration Statement would include any untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein in the light of the circumstances under which they were
     made not misleading, or (2) it shall be necessary to amend such
     Registration Statement or supplement the related prospectus, to comply with
     the Securities Act or the Exchange Act or the respective rules thereunder.

     (b) If a Registration Default has occurred and is continuing, for the first
90-day period following the occurrence of the first Registration Default, the
Issuers will pay Liquidated Damages to each holder of Transfer Restricted
Securities ("Restricted Holder") in the amount of $0.05 per week per $1,000
principal amount of the Transfer Restricted Securities then held by such
Restricted Holder. The amount of Liquidated Damages payable by the Issuers to
each Restricted Holder will increase by an additional $0.05 per week per $1,000
principal amount of the Transfer Restricted Securities then held by such
Restricted Holder for each subsequent 90-day period for which a Registration
Default is continuing until all Registration Defaults have been cured; provided,
however that the maximum amount of Liquidated Damages for all Registration
Defaults payable by the Issuers to each Restricted Holder will not exceed $0.50
per week per $1,000 principal amount of Transfer Restricted Securities then held
by such Restricted Holder. Following the cure of all Registration Defaults, the
accrual of Liquidated Damages will cease.

                                       18
<Page>

     (c) A Registration Default referred to in Section 6(a)(iv)(B) hereof shall
be deemed not to have occurred and be continuing in relation to a Shelf
Registration Statement or the related prospectus if (i) such Registration
Default has occurred solely as a result of (x) the filing of a post-effective
amendment to such Shelf Registration Statement to incorporate annual audited
financial information with respect to the Issuers where such post-effective
amendment is not yet effective and needs to be declared effective to permit
Holders to use the related prospectus or (y) other material events, with respect
to the Issuers that would need to be described in such Shelf Registration
Statement or the related prospectus and (ii) in the case of clause (y), the
Issuers are proceeding promptly and in good faith to amend or supplement such
Shelf Registration Statement and related prospectus to describe such events;
provided, however, that in any case if such Registration Default occurs for a
continuous period in excess of 30 days, Liquidated Damages shall be payable in
accordance with the above paragraph from the day such Registration Default
occurs until such Registration Default is cured.

     (d) All accrued Liquidated Damages will be paid by the Issuers on the next
scheduled interest payment date to the paying agent or its nominees by wire
transfer of immediately available funds or by federal funds check and to the
holders of certificated notes by wire transfer to the accounts specified by such
notes or by mailing checks to the holder's registered address if no account has
been specified.

     (e) "Transfer Restricted Securities" means each Security until (i) the date
on which such Transfer Restricted Security has been exchanged by a person other
than a broker-dealer for a freely transferable Exchange Security in the
Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the
Registered Exchange Offer of a Initial Security for an Exchange Security, the

     Each broker-dealer that receives Exchange Securities for its own account in
exchange for Securities, where such Initial Securities were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Securities. See "Plan of Distribution."

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives Exchange Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Securities received in

transactions, through the writing of options on the Exchange Securities or a
combination of such methods of resale, at market prices prevailing at the time

concessions from any such broker-dealer or the purchasers of any such Exchange
Securities. Any broker-dealer that resells Exchange Securities that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such Exchange Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that, by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

     For a period of 180 days after the Expiration Date, the Issuers will
promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such documents
