                  proposes to transfer such Note 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
            Company so requests, an Opinion of Counsel in form reasonably
            acceptable to the Company to the effect that such exchange or
            transfer is in compliance with the Securities Act and that the
            restrictions on transfer contained herein and in the Private
            Placement Legend are no longer required in order to maintain
            compliance with the Securities Act.

            (iii) 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 shall issue and,

interests in the Restricted Global Notes tendered for acceptance by Persons that
certify in the applicable Letters of Transmittal that (x) they are not
Broker-Dealers, (y) they are not participating in a distribution of the Exchange
Notes and (z) they are not affiliates (as defined in Rule 144) of the Company,
and accepted for exchange in the Exchange Offer and (ii) Definitive Notes in an

Definitive Notes accepted for exchange in the Exchange Offer. Concurrently with
the issuance of such Notes, the Trustee shall cause the aggregate principal
amount of the applicable Restricted Global Notes to be reduced accordingly, and
the Company shall execute and the Trustee shall authenticate and deliver to the
Persons designated by the Holders of Definitive Notes so accepted Definitive
Notes in the appropriate principal amount.

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 shall be returned to or
retained and canceled by the Trustee in accordance with SECTION 2.10 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 shall be
reduced accordingly and an endorsement shall 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 shall be increased accordingly

      Definitive Notes upon the Company's written order or at the Registrar's
      written request.

            (ii) No service charge shall 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 2.9, 7.5 and 10.2 hereof).

      of or exchange any Note selected for redemption in whole or in part,
      except the unredeemed portion of any Note being redeemed in part.

            (iv) All Global Notes and Definitive Notes issued upon any
      registration of transfer or exchange of Global Notes or Definitive Notes
      shall 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.

            (v) The Company shall not 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 ARTICLE 10 hereof and ending at the close of business on
      the day of selection, (B) to register the transfer of or to exchange any
      Note so 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

            (vi) 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.

            (vii) The Trustee shall authenticate Global Notes and Definitive
      Notes in accordance with the provisions of SECTION 2.2 hereof.

      effect a registration of transfer or exchange may be submitted by
      facsimile but originals of such opinions shall follow by mail.

SECTION 2.7        REPLACEMENT NOTES.

      If any mutilated Note is surrendered to the Trustee or the Company or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, the Company shall issue and the Trustee, upon receipt of an
Authentication Order, shall 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
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

                                      24

SECTION 2.8        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 as
not outstanding. Except as set forth in SECTION 6.4 hereof, a Note does not
cease to be outstanding because the Company or an Affiliate of the Company holds
the Note.

      If a Note is replaced pursuant to SECTION 2.7 hereof it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

      If the principal amount of any Note is considered paid under SECTION 3.1
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 shall
be deemed to be no longer outstanding and shall cease to accrue interest.

SECTION 2.9        TEMPORARY NOTES.

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

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

SECTION 2.10       CANCELLATION.

      The Company at any time may deliver Notes to the Trustee for cancellation.
The Registrar and Paying Agent shall forward to the Trustee any Notes
surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall dispose of
the canceled Notes pursuant to its customary practices and procedures in effect
from time to time (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all canceled Notes shall be delivered
to the Company. The Company may not issue new Notes to replace Notes that it has
paid or that have been delivered to the Trustee for cancellation, except as
otherwise provided for herein.

SECTION 2.11       DEFAULTED INTEREST.

      If the Company defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest,

                                      25
<Page>

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 3.1 hereof. The Company shall
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 shall fix or
cause to be fixed each such special record date and payment date, PROVIDED that
no such special record date shall 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) shall 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.

SECTION 3.1        PAYMENT OF PRINCIPAL AND INTEREST.

      The Company shall duly and punctually pay or cause to be paid the
principal of, and premium, if any, and interest on, each of the Notes at the
place or places, at the respective times and in the manner provided in this
Indenture and the Notes. Payment of principal of, and premium and interest on
the Notes shall be paid by mailing a check to or upon the written order of the
registered Holders of Notes entitled thereto at their last address as it appears
on the Notes Register or, upon written application to the Trustee (which shall
be received by the Trustee prior to the record date) by a Holder of $1,000,000
or more in aggregate principal amount of Notes, by wire transfer of immediately
available funds to an account maintained by such Holder with a bank or other
financial institution; PROVIDED, HOWEVER that (subject to the provisions of
SECTION 2.7 hereof) payment of principal of, and premium, if any, on any Note
may be conditioned upon presentation for payment of the certificate representing
such Note.

      The Company shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Notes to the
extent lawful, and it shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace period) at the same rate to the extent
lawful.

      If a Reporting Cessation occurs, the interest rate applicable to the Notes
shall be increased by 0.50% per annum from the date such Reporting Cessation
occurs until such time as the Reporting Cessation has ended.

      The Company, whenever necessary to avoid or fill a vacancy in the office
of Trustee, shall appoint, in the manner provided in SECTION 5.9 hereof, a
Trustee, so that there shall at all times be a Trustee hereunder.

knowledge of the Company's compliance with all covenants under this Indenture
(such compliance to be determined without regard to any period of grace or
requirement of notice provided under this Indenture) and (ii) upon becoming
aware of any Default or Event of Default, a statement specifying such Default or
Event of Default. Within 30 days of its becoming aware of any Default or Event
of Default, the Trustee shall provide the Holders with a notice specifying such
Default or Event of Default.

SECTION 3.4        REPORTS BY THE COMPANY.

      The Company shall deliver to the Trustee and provide Noteholders, within
15 days after it files them with the Commission, copies of its annual reports
and of the information, documents and other reports that the Company is required
to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act,
and shall deliver to the Trustee copies of any other report that the Company
files with the Commission. Delivery of such reports, information and documents
to the Trustee is for informational purposes only and the Trustee's receipt of
such shall not constitute constructive notice of any information contained
therein, including the Company's compliance with any of its covenants contained
hereunder.

      Following the effectiveness of any registration statement pursuant to the
Registration Rights Agreement, whether or not required by the rules and
regulations of the Commission, the Company shall maintain its status as a
reporting company under the Exchange Act, and file copies of all such
information and reports with the Commission for public availability (unless the
Commission will not accept such filings) within the time periods specified in
the Commission's rules and regulations and make such information available to
securities analysts and prospective investors upon request; and if at any time
the Company fails to maintain its status as a reporting company under the
Exchange Act (a "REPORTING CESSATION"), the interest rate on the Notes will be
increased by 0.50% on an annual basis, provided that no Reporting Cessation
shall be deemed to occur if the Commission does not accept the information and
reports of the Company to be filed pursuant to the Exchange Act.

SECTION 3.5        RESTRICTIONS ON LIENS.

      The Company shall not:

      (i) pledge, mortgage, hypothecate or permit to exist any mortgage, pledge

      (ii) cause or permit any of its subsidiaries to pledge, mortgage,
hypothecate or permit to exist any mortgage, pledge or other lien upon any

         exceed $100 million in the aggregate;

     (4) liens granted in connection with extending, renewing, replacing or
         refinancing in whole or in part the Indebtedness (including, without

         described in clauses (1) through (3) above; and

     (5) liens granted by any of the Company's subsidiaries on the capital
         stock or assets of any project subsidiary in order to secure any of

         proceeds of which are used to finance the equity contributed by the
         Company, or loans made by the Company, to a project) in order to
         finance or refinance any acquisition, development, construction,

shall give prior written notice thereof to the Trustee, who shall give notice to
the Holders, and the Company shall, prior to or simultaneously with such pledge,

liquidator, assignee, custodian, trustee, sequestrator or similar official of
the Company or for any substantial part of its property or ordering the winding
up or liquidation of its affairs, shall have been entered, and such decree or
order shall remain unstayed and in effect for a period of 90 consecutive days;
or

      (g) the Company shall commence a voluntary case or proceeding under any
applicable federal or state bankruptcy, insolvency, reorganization or other
similar law now or hereafter in effect or of any other case or proceeding to be
adjudicated a bankrupt or insolvent, or consent to the entry of a decree or
order for relief in an involuntary case or proceeding under any such law, or to
the commencement of any bankruptcy or insolvency case or proceeding against the
Company, or the filing by the Company of a petition or answer or consent seeking
reorganization or relief under any such applicable federal or state law, or the
consent by the Company to the filing of such petition or to the appointment of
or the taking possession by a custodian, receiver, liquidator, assignee,
trustee, sequestrator or other similar official of the Company or of any
substantial part of its property, or the making by the Company of an assignment
for the benefit of creditors, or the taking of action by the Company in
furtherance of any such action;

then and in each and every such case (other than an Event of Default with
respect to the Company specified in SECTION 4.1(f) or 4.1(g) hereof), unless the
principal amount of all of the Notes shall have already become due and payable,
either the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Notes (including Additional Notes, if any) then

                                      30
<Page>

Outstanding hereunder, by notice in writing to the Company (and to the Trustee
if given by Noteholders), may declare the entire principal amount of all the
Notes and the interest accrued thereon to be due and payable immediately, and
upon any such declaration the same shall become immediately due and payable.
This provision, however, is subject to the condition that if, at any time after
the principal of the Notes shall have been so declared due and payable, and
before any judgment or decree for the payment of the moneys due shall have been
obtained or entered as hereinafter provided, the Company shall pay or shall
deposit with the Trustee a sum sufficient to pay all matured installments of
interest upon all the Notes and the principal and premium, if any, of any and
all Notes that shall have become due otherwise than by acceleration (with
interest upon such principal and premium, if any, and, to the extent that
payment of such interest is enforceable under applicable law, on overdue
installments of interest, at the rate of interest specified in the Notes, to the
date of such payment or deposit) and such amount as shall be sufficient to cover
reasonable compensation to the Trustee and each predecessor Trustee, their
respective agents, attorneys and counsel, and all other reasonable expenses and
liabilities incurred and all reasonable advances made by the Trustee and each
predecessor Trustee except as a result of gross negligence or bad faith, and if
any and all Events of Default under this Indenture, other than the non-payment
of the principal that shall have become due by acceleration, shall have been
cured, waived or otherwise remedied as provided herein, then and in every such
case the Holders of a majority in aggregate principal amount of the Notes then
Outstanding, by written notice to the Company and to the Trustee, may waive all
defaults (except, unless theretofore cured, a default in payment of principal
of, or premium, if any, or interest on, the Notes) and rescind and annul such
declaration and its consequences, but no such waiver or rescission and annulment
shall extend to or shall affect any subsequent default or shall impair any right
consequent thereon.

      If an Event of Default specified in SECTION 4.1(f) or 4.1(g) hereof occurs
with respect to the Company, the principal of and accrued interest on the Notes
shall become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Noteholder.

SECTION 4.2        COLLECTION OF INDEBTEDNESS BY TRUSTEE; TRUSTEE MAY PROVE
                   DEBT.

      The Company covenants that (a) in case default shall be made in the
payment of any installment of interest on any of the Notes when such interest
shall have become due and payable, and such default shall have continued for a
period of 30 days or (b) in case default shall be made in the payment of all or
any part of the principal of, or premium, if any, on, any of the Notes when the
same shall have become due and payable, whether upon maturity or upon any
redemption or by declaration or acceleration or otherwise, then upon demand of
the Trustee, the Company shall pay to the Trustee for the benefit of the Holders
of the Notes the whole amount that then shall have become due and payable on all
such Notes of principal, premium and interest, as the case may be (with interest
to the date of such payment upon the overdue principal or premium and, to the
extent that payment of such interest is enforceable under applicable law, on
overdue installments of interest at the rate of interest specified in the
Notes), and in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, including reasonable compensation to
the Trustee and each predecessor Trustee, their respective agents, attorneys and
counsel, and any reasonable expenses and liabilities incurred, and all

                                      31
<Page>

reasonable advances made, by the Trustee and each predecessor Trustee, except as
a result of its gross negligence or bad faith.

      Until such demand is made by the Trustee, the Company may pay the
principal of and premium and interest on the Notes to the registered Holders,
whether or not the Notes are overdue.

      In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceeding at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceedings to judgment or final decree, and may enforce any such
judgment or final decree against the Company or other obligor upon the Notes and
collect in the manner provided by law out of the property of the Company or
other obligor upon the Notes, wherever situated, the moneys adjudged or decreed
to be payable.

      In case there shall be pending proceedings relative to the Company or any
other obligor upon the Notes under Title 11 of the United States Code or any
other applicable federal or state bankruptcy, insolvency or other similar law,
or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, custodian, sequestrator or similar official shall have been
appointed for or taken possession of the Company or its property or such other
obligor, or in case of any other comparable judicial proceedings relative to the
Company or other obligor upon the Notes, or to the creditors or property of the
Company or such other obligor, the Trustee, irrespective of whether the
principal of the Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective or whether the Trustee shall have made
any demand pursuant to the provisions of this SECTION 4.2, shall be entitled and
empowered, by intervention in such proceedings or otherwise:

      (a) to file and prove a claim or claims for the whole amount of principal,
premium and interest owing and unpaid in respect of the Notes, and to file such
other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for reasonable compensation to the
Trustee and each predecessor Trustee, and their respective agents, attorneys and
counsel, and for reimbursement of all reasonable expenses and liabilities
incurred, and all reasonable advances made, by the Trustee and each predecessor
Trustee, except as a result of gross negligence or bad faith) and of the
Noteholders, allowed in any judicial proceedings relative to the Company or
other obligor upon the Notes, or to the creditors or property of the Company or
such other obligor;

      (b) unless prohibited by applicable law and regulations, to vote on behalf
of the Holders of the Notes in any election of a trustee or a standby trustee in
arrangement, reorganization, liquidation or other bankruptcy or insolvency
proceedings or person performing similar functions in comparable proceedings;
and

      (c) to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute all amounts received with
respect to the claims of the Noteholders and of the Trustee on their behalf; and
any trustee, receiver, or liquidator, custodian or other similar official is
hereby authorized by each of the Noteholders to make payments to the Trustee,

                                      32
<Page>

and, in the event that the Trustee shall consent to the making of payments
directly to the Noteholders, to pay to the Trustee such amounts as shall be
sufficient to cover reasonable compensation to the Trustee, each predecessor
Trustee and their respective agents, attorneys and counsel, and all other
reasonable expenses and liabilities incurred, and all reasonable advances made,
by the Trustee and each predecessor Trustee except as a result of negligence or
bad faith.

      Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Noteholders any plan or reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Noteholder in any such proceeding
except, as aforesaid, to vote for the election of a trustee in bankruptcy or
similar person.

      All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Trustee without the possession of
any of the Notes or the production thereof at any trial or other proceeding
relative thereto, and any such action or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment, subject to the payment of the expenses, disbursements and
compensation of the Trustee, each predecessor Trustee and their respective
agents and attorneys, shall be for the ratable benefit of the Holders of the
Notes.

      In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party), the Trustee shall be held to represent all the
Holders of the Notes, and it shall not be necessary to make any Holders of the
Notes parties to any such proceedings.

SECTION 4.3        APPLICATION OF PROCEEDS.

      Any moneys collected by the Trustee pursuant to this Article shall be
applied in the following order at the date or dates fixed by the Trustee and, in
case of the distribution of such moneys on account of principal or interest,
upon presentation of the several Notes and stamping (or otherwise noting)
thereon the payment, or issuing Notes in reduced principal amounts in exchange
for the presented Notes if only partially paid, or upon surrender thereof if
fully paid:

      FIRST: To the payment of costs and expenses, including reasonable
compensation to the Trustee and each predecessor Trustee and their respective
agents and attorneys and of all reasonable expenses and liabilities incurred,
and all reasonable advances made, by the Trustee and each predecessor Trustee,
except as a result of gross negligence or bad faith, and all other amounts due
under SECTION 5.6 hereof;

      SECOND: In case the principal and premium, if any, of the Notes shall not
have become and be then due and payable, to the payment of interest in default
in the order of the maturity of the installments of such interest, with interest
(to the extent that such interest has been collected by the Trustee) upon the
overdue installments of interest payable at the rate of interest specified in
the Notes, such payments to be made ratably to the persons entitled thereto,
without discrimination or preference;

                                      33
<Page>

      THIRD: In case the principal of the Notes shall have become and shall be
then due and payable, to the payment of the whole amount then owing and unpaid
upon all the Notes for principal, premium and interest, with interest upon the
overdue principal and premium, if any, and (to the extent that such interest has
been collected by the Trustee) upon overdue installments of interest payable at
the rate of interest specified in the Notes, and in case such moneys shall be
insufficient to pay in full the whole amount so due and unpaid upon the Notes,
then to the payment of such principal, premium and interest, without preference
or priority of principal or premium over interest, or of interest over principal
or premium, or of any installment of interest over any other installment of
interest, or of any Note over any other Note, ratably to the aggregate of such
principal, premium and accrued and unpaid interest; and

      FOURTH:  To the payment of the remainder, if any, to the Company or any
other Person lawfully entitled thereto.

      The Trustee may fix a record date and payment date for any payment to
Noteholders pursuant to this SECTION 4.3.

SECTION 4.4        SUITS FOR ENFORCEMENT.

      In case an Event of Default has occurred, has not been waived and is
continuing, the Trustee may proceed to protect and enforce the rights vested in
it by this Indenture by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any of such rights, either at
law or in equity or in bankruptcy or otherwise, whether for the specific
enforcement of any covenant or agreement contained in this Indenture or in aid
of the exercise of any power granted in this Indenture or to enforce any other
legal or equitable right vested in the Trustee by this Indenture or by law.

SECTION 4.5        RESTORATION OF RIGHTS ON ABANDONMENT OF PROCEEDINGS.

      In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned for any
reason, or shall have been determined adversely to the Trustee, then and in
every such case the Company and the Trustee shall be restored respectively to
their former positions and rights hereunder, and all rights, remedies and powers
of the Company, the Trustee and the Noteholders shall continue as though no such
proceedings had been taken.

SECTION 4.6        LIMITATIONS OF SUITS BY NOTEHOLDERS.

      Subject to SECTION 4.10, no Holder of any Note shall have any right by
virtue or by availing of any provision of this Indenture to institute any action
or proceeding at law or in equity or in bankruptcy or otherwise upon or under or
with respect to this Indenture, or for the appointment of a trustee, receiver,
liquidator, custodian or other similar official or for any other remedy
hereunder, unless (i) such Holder previously has given to a Responsible Officer
of the Trustee written notice of default and of the continuance hereof, as
hereinbefore provided, (ii) the Holders of not less than 25% in aggregate
principal amount of the Notes then Outstanding have made written request upon
the Trustee to institute such action or proceeding in its own name as

                                      34
<Page>

Trustee hereunder and have offered to the Trustee such reasonable security and
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, (iii) the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity has failed to institute any such
action or proceeding and (iv) no direction inconsistent with such written
request has been given to the Trustee pursuant to SECTION 4.8 hereof; it being
understood and intended, and being expressly covenanted by the taker and Holder
of every Note with every other taker and Holder and the Trustee, that no one or
more Holders of Notes shall have any right in any manner whatever by virtue or
by availing of any provision of this Indenture to affect, disturb or prejudice
the rights of any other Holder of Notes, or to obtain or seek to obtain priority
over or preference to any other such Holder or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and
common benefit of all Holders of Notes. For the protection and enforcement of
the provisions of this SECTION 4.6, each and every Noteholder and the Trustee
shall be entitled to such relief as can be given either at law or in equity.

SECTION 4.7        POWERS AND REMEDIES CUMULATIVE, DELAY OR OMISSION NOT WAIVER
                   OF DEFAULT.

      No right or remedy herein conferred upon or reserved to the Trustee or to
the Noteholders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

      No delay or omission of the Trustee or of any Holder of any of the Notes
to exercise as aforesaid any such right or power accruing upon any Event of
Default occurring and continuing as aforesaid shall impair any such right or
power or shall be construed to be a waiver of any such Event of Default or an
acquiescence therein; and, subject to SECTION 4.6 hereof, every power and remedy
given by this Indenture or by law to the Trustee or to the Noteholders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Noteholders.

SECTION 4.8        CONTROL BY NOTEHOLDERS.

      The Holders of a majority in aggregate principal amount of the Notes at
the time Outstanding shall have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee by this Indenture;
PROVIDED that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture; and PROVIDED FURTHER that (subject to the
provisions of SECTION 5.1 hereof) the Trustee shall have the right to decline to
follow any such direction if the Trustee, being advised by counsel, shall
determine that the action or proceeding so directed may not lawfully be taken or
if the Trustee in good faith by its board of directors, the executive committee,
or a trust committee of directors or Responsible Officers of the Trustee shall
determine that the action or proceedings so directed would involve the Trustee
in personal liability, or if the Trustee in good faith shall so determine that
the actions or forbearances specified in or pursuant to such direction shall be
unduly prejudicial to the interests of Holders of

                                      35
<Page>

the Notes not joining in the giving of said direction, it being understood that
(subject to SECTION 5.1 hereof) the Trustee shall have no duty to ascertain
whether or not such actions or forbearances are unduly prejudicial to such
Holders.

      Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by Noteholders.

Section 4.9        WAIVER OF PAST DEFAULTS.

      Prior to the declaration of the maturity of the Notes as provided in
SECTION 4.1 hereof, the Holders of a majority in aggregate principal amount of
the Notes at the time Outstanding may on behalf of the Holders of all the Notes
waive any past Default or Event of Default hereunder and its consequences,
except a Default (a) in the payment of principal of, premium, if any, or
interest on any of the Notes or (b) in respect of a covenant or provision hereof
that cannot be modified or amended without the consent of the Holder of each
Note affected. In the case of any such waiver, the Company, the Trustee and the
Holders of the Notes shall be restored to their former positions and rights
hereunder, respectively, but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

      Upon any such waiver, such default shall cease to exist and be deemed to
have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured, and not to have occurred for every
purpose of this Indenture, but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

Section 4.10       RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

      Notwithstanding any other provision of this Indenture (including, without
limitation, SECTION 4.6 hereof), the right of any Holder to receive, and to
institute suit to enforce, payment of the principal of, and premium, if any, and
interest on the Notes on or after the respective due dates expressed in such
Notes (including upon redemption and acceleration of the maturity of the
principal of and premium, if any, and interest on the Notes), shall not be
affected or impaired, and shall be absolute and unconditional.

                                    ARTICLE 5
                             CONCERNING THE TRUSTEE

Section 5.1        DUTIES AND RESPONSIBILITIES OF THE TRUSTEE DURING DEFAULT
AND PRIOR TO DEFAULT.

      The Trustee, prior to the occurrence of an Event of Default and after the
curing or waiving of all Events of Default that may have occurred, undertakes to
perform only such duties as are specifically set forth in this Indenture. In
case an Event of Default has occurred (which has not been cured or waived), the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and shall use the same degree of care and skill in their exercise, as
a prudent person would exercise or use under the circumstances in the conduct of
his own affairs.

                                      36
<Page>

      No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct, except that:

      (a) prior to the occurrence of an Event of Default and after the curing or
waiving of all such Events of Default that may have occurred:

            (i) the duties and obligations of the Trustee shall be determined
      solely by the express provisions of this Indenture, and the Trustee shall
      not be liable except for the performance of such duties and obligations as
      are specifically set forth in this Indenture, and no implied covenants or
      obligations shall be read into this Indenture against the Trustee; and

            (ii) in the absence of bad faith on the part of the Trustee, the
      Trustee may conclusively rely, as to the truth of the statements and the
      correctness of the opinions expressed therein, upon any statements,
      certificates or opinions furnished to the Trustee and conforming to the
      requirements of this Indenture; but in the case of any such statements,
      certificates or opinions which by any provision hereof are specifically
      required to be furnished to the Trustee, the Trustee shall be under a duty
      to examine the same to determine whether or not they conform to the
      requirements of this Indenture;

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

      (c) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of the
Holders of not less than a majority in principal amount of the Notes at the time
Outstanding relating to the time, method and place of conducting any proceeding
for any remedy available to the Trustee, or exercising any trust or power
conferred upon the Trustee, under this Indenture.

      None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers.

SECTION 5.2        CERTAIN RIGHTS OF THE TRUSTEE.

      Subject to SECTION 5.1 hereof:

      (a) the Trustee may conclusively rely and shall be fully protected in
acting or refraining from acting upon any resolution, Officers' Certificate or
any other certificate (including, without limitation, any certificate provided
to the Trustee pursuant to SECTION 3.3 hereof), statement, instrument, opinion,
report, notice, request, consent, order, bond, debenture, note, coupon, security
or other paper document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

                                      37
<Page>

      (b) any request, direction, order or demand of the Company mentioned

evidence in respect thereof be herein specifically prescribed) and any
resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the Secretary or an Assistant Secretary of the Company;

      (c) the Trustee may consult with counsel of its selection and any advice

or powers vested in it by this Indenture at the request, order or direction of

satisfactory to it against the costs, expenses and liabilities that might be
incurred therein or thereby;

in writing to do so by the Holders of not less than a majority in aggregate
principal amount of the Notes then Outstanding; PROVIDED that if the payment
within a reasonable time to the Trustee of the costs, expenses or liabilities
likely to be incurred by it in the making of such investigation is, in the
opinion of the Trustee, not reasonably assured by the security afforded to it by
the terms of this Indenture, the Trustee may require indemnity reasonably
satisfactory to it against such expenses or liabilities as a condition to
proceeding, and the reasonable expenses of every such examination shall be paid
by the Company, or by the Trustee or any predecessor Trustee and repaid by the
Company upon demand;

      (g) the Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the Trustee
may make such further inquiry or investigation into such facts or matters as it
may see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney;

      (h) in the absence of bad faith on the part of the Trustee, the Trustee
may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon any certificates or opinions furnished to
the Trustee which conform to the requirements of this Indenture;

                                      38
<Page>

      (i) the Trustee shall not be liable for any error of judgment made in good
faith by an officer or officers of the Trustee, unless it shall be conclusively
determined by a court of competent jurisdiction that the Trustee was grossly
negligent in ascertaining the pertinent facts;

perform any duties hereunder either directly or by or through agents, attorneys,
custodians or nominees appointed with due care, and shall not be responsible for
any willful misconduct or gross negligence on the part of any agent, attorney,
custodian or nominee so appointed;

      (k) the Trustee shall not be deemed to have notice of an Event of Default
unless a Responsible Officer of the Trustee has actual knowledge thereof or
written notice of any Event of Default is received by the Trustee at its
Corporate Trust Office;

      (l) 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 to each agent, custodian and other person appointed with due care
pursuant to the provisions hereunder to act hereunder; and 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, which Officers' Certificate may be
signed by any person authorized to sign an Officers' Certificate, including any
person specified as so authorized in any such certificate previously delivered
and not superseded.

                   APPLICATION OF PROCEEDS THEREOF.

      The recitals contained herein and in the Notes, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for the correctness of the same. The
Trustee makes no representation as to the validity or sufficiency of this
Indenture or of the Notes. The Trustee shall not be accountable for the use or
application by the Company of any of the Notes or of the proceeds thereof.

SECTION 5.4        TRUSTEE AND AGENTS MAY HOLD NOTES; COLLECTIONS, ETC.

      The Trustee or any agent of the Company or the Trustee, in its individual
or any other capacity, may become the owner or pledgee of Notes with the same

the Trustee shall, until used or applied as herein provided, be held in trust

other funds except to the extent required by mandatory provisions of law.
Neither the Trustee nor any agent of the Company or the Trustee shall be

                                      39

to time, and the Trustee shall be entitled to reasonable compensation (which
shall not be limited by any provision of law relating to the compensation of a
trustee of an express trust), and the Company covenants and agrees to pay or
reimburse the Trustee and each predecessor Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by or on behalf
of it in accordance with any of the provisions of this Indenture (including the
reasonable compensation and expenses and disbursements of its counsel and of all
agents and other persons not regularly in its employ), except to the extent any
such expense, disbursement or advance may arise from the Trustee's gross
negligence or bad faith. The Company also covenants to indemnify the Trustee and
each predecessor Trustee for, and to hold it harmless against, any and all loss,
liability, damage, claims or expenses , including taxes (other than taxes based
on the income of the Trustee), arising out of or in connection with the
acceptance or administration of this Indenture or the trusts hereunder and its
duties hereunder and the performance of its duties hereunder, including the
costs and expenses of defending and investigating any claim of liability in the
premises, except to the extent any such loss, liability or expense is due to its
own gross negligence or bad faith. The obligations of the Company under this
SECTION 5.6 to compensate and indemnify the Trustee and each predecessor Trustee
and to pay or reimburse the Trustee and each predecessor Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder
and shall survive the termination or satisfaction and discharge of this
Indenture.

SECTION 5.7        RIGHT OF TRUSTEE TO RELY ON OFFICERS' CERTIFICATE, ETC.

      Subject to SECTION 5.1 and SECTION 5.2 hereof, whenever in the
administration of the trusts of this Indenture the Trustee shall deem it
necessary or desirable that a matter be proved or established prior to taking or
suffering or omitting any action hereunder, such matter (unless other evidence
in respect thereof be herein specifically prescribed) may, in the absence of
gross negligence or bad faith on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Trustee.

SECTION 5.8        PERSONS ELIGIBLE FOR APPOINTMENT AS TRUSTEE.

      The Trustee hereunder shall at all times be a corporation organized and
doing business under the laws of the United States or of a state thereof having
a combined capital and surplus of at least $50,000,000, and which is authorized
under such laws to exercise corporate trust powers and is subject to supervision
or examination by federal or state authority. If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of a federal, state or District of Columbia supervising or examining authority,
then for the purposes of this SECTION 5.8, the combined capital and surplus of
such corporation shall be deemed to be its combined capital and surplus as set
forth in its most recent report of condition so published. No

                                      40
<Page>

obligor on the Notes or Person directly or indirectly controlling, controlled by
or under common control with such obligor shall serve as Trustee.

SECTION 5.9        RESIGNATION AND REMOVAL, APPOINTMENT OF SUCCESSOR TRUSTEE.

      (a) The Trustee may at any time resign by giving written notice of
resignation to the Company and by mailing notice thereof by first-class mail to
Holders of Notes at their last addresses as they shall appear on the Notes
Register. Upon receiving such notice of resignation, the Company shall promptly
appoint a successor trustee by written instrument in duplicate, executed by
authority of the Board of Directors, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor Trustee. If no
such successor trustee shall have been so appointed and have accepted
appointment within 30 days after the mailing of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction, at the
expense of the Company, for the appointment of a successor trustee, or any
Noteholder who has been a bona fide Holder of a Note or Notes for at least six
months may, on behalf of itself and all others similarly situated, petition any
such court for the appointment of a successor trustee. Such court may thereupon,
after such notice, if any, as it may deem proper and prescribe, appoint a
successor trustee.

      (b)   In case at any time any of the following shall occur:

            (i) the Trustee shall fail to comply with the provisions of TIA
      Section 310(b), after written request thereafter by the Company or by any
      Noteholder who has been a bona fide Holder of a Note or Notes for at least
      six months;

            (ii) the Trustee shall cease to be eligible in accordance with the
      provisions of SECTION 5.8 hereof and shall fail to resign after written
      request therefor by the Company or by any such Noteholder; or

            (iii) the Trustee shall become incapable of acting, or shall be
      adjudged a bankrupt or insolvent, or a receiver or liquidator of the
      Trustee or of its property shall be appointed, or any public officer shall
      take charge or control of the Trustee or of its property or affairs for
      the purpose of rehabilitation, conservation or liquidation;

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors of the Company, one copy of which instrument shall be
delivered to the Trustee so removed and one copy of which shall be delivered to
the successor trustee, or any Noteholder who has been a bona fide Holder of a
Note or Notes for at least six months may, on behalf of itself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe,
remove the Trustee and appoint a successor trustee.

      (c) The Holders of a majority in aggregate principal amount of the Notes
at the time Outstanding may at any time remove the Trustee and appoint a
successor trustee by delivering to

                                      41
<Page>

the Trustee so removed, to the successor trustee so appointed and to the Company
the evidence provided for in SECTION 6.1 hereof of the action in that regard
taken by the Noteholders.

      (d) Any resignation or removal of the Trustee and any appointment of a
successor trustee pursuant to any of the provisions of this SECTION 5.9 shall
become effective only upon acceptance of appointment by the successor trustee as
provided in SECTION 5.10 hereof.

SECTION 5.10       ACCEPTANCE OF APPOINTMENT BY SUCCESSOR TRUSTEE.

      Any successor trustee appointed as provided in SECTION 5.9 hereof shall
execute and deliver to the Company and to its predecessor Trustee an instrument
accepting such appointment hereunder, and thereupon the resignation or removal
of the predecessor Trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become vested with all
rights, powers, duties and obligations of its predecessor hereunder, with like
effect as if originally named as trustee herein; but, nevertheless, on the
written request of the Company or of the successor trustee, upon payment of its
charges then unpaid, the Trustee ceasing to act shall, subject to SECTION 9.4
hereof, pay over to the successor trustee all moneys at the time held by it
hereunder and shall execute and deliver an instrument transferring to such
successor trustee all such rights, powers, duties and obligations. Upon request
of any such successor trustee, the Company shall execute appropriate instruments
in writing for more fully and certainly vesting in and confirming to such
successor such rights and powers. Any Trustee ceasing to act shall,
nevertheless, retain a prior claim upon all property or funds held or collected
by such Trustee to secure any amounts then due it pursuant to the provisions of
SECTION 5.6 hereof.

      Upon acceptance of appointment by a successor trustee as provided in this
SECTION 5.10, the Company shall mail notice thereof by first-class mail to the
Holders of Notes at their last addresses as they shall appear in the Notes
Register. If the acceptance of appointment is substantially contemporaneous with
a resignation, then the notice called for by the preceding sentence may be
combined with the notice called for by SECTION 5.9 hereof. If the Company fails
to mail such notice within 10 days after acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be mailed at
the expense of the Company.

      Notwithstanding replacement of the Trustee pursuant to this SECTION 5.10,
the Company's obligations under SECTION 5.6 hereof shall continue for the
benefit of the retiring Trustee.

SECTION 5.11       MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS
                   OF TRUSTEE.

      Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder, as
long as such corporation shall be eligible under the provisions of SECTION 5.8
hereof, without the execution or filing of any paper or any further act on the
part of any of the parties hereto, anything herein to the contrary
notwithstanding.

                                      42
<Page>

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

SECTION 5.12       REPORTS BY TRUSTEE.

      The Trustee shall provide to the Holders the reports required to be
provided by the Trustee pursuant to Section 313 of the TIA.

SECTION 5.13       NO LIABILITY FOR CLEAN-UP OF HAZARDOUS MATERIALS.

      In the event that the Trustee is required to acquire title to an asset for
any reason, or take any managerial action of any kind in regard thereto, in
order to carry out any fiduciary or trust obligation for the benefit of another,
which in the Trustee's sole discretion may cause the Trustee to be considered an
"owner or operator" under the provisions of the Comprehensive Environmental
Response, Compensation and Liability Act (CERCLA) 42 U.S.C. Section 9601, et
seq., or otherwise cause the Trustee to incur liability under CERCLA or any
other federal, state or local law, the Trustee reserves the right to, instead of
taking such action, either resign as Trustee pursuant to the provisions
hereunder or arrange for the transfer of the title or control of the asset to a
court appointed receiver.

      The Trustee shall not be liable to the Company or any other person for any
environmental claims or contribution actions under any federal, state or local
law, rule or regulation by reason of the Trustee's actions and conduct as
authorized, empowered and directed hereunder or relating to the discharge,
release or threatened release of hazardous materials into the environment.

SECTION 5.14       APPOINTMENT OF CO-TRUSTEE.

        It is the purpose of this Indenture that there shall be no violation of
any law of any jurisdiction (including particularly the law of any State)
denying or restricting the right of banking corporations or associations to
transact business as trustee in such jurisdiction. It is recognized that in case
of litigation under this Indenture, and in particular in case of the enforcement
thereof on default, or in case the Trustee deems that by reason of any present
or future law of any jurisdiction it may not exercise any of the powers, rights
or remedies herein granted to the Trustee or hold title to the properties, in
trust, as herein granted or take any action which may be desirable or necessary
in connection therewith, it may be necessary that the Trustee appoint an
individual or institution as a separate or co-trustee. The following provisions
of this Section are adopted to these ends.

                                      43
<Page>

      In the event that the Trustee appoints an additional individual or
institution as a separate or co-trustee, each and every remedy, power, right,
claim, demand, cause of action, immunity, estate, title, interest and lien
expressed or intended by this Indenture to be exercised by or vested in or
conveyed to the Trustee with respect thereto shall be exercisable by and vest in
such separate or co-trustee but only to the extent necessary to enable such
separate or co-trustee to exercise such powers, rights and remedies, and only to
the extent that the Trustee by the laws of any jurisdiction (including
particularly any State) is incapable of exercising such powers, rights and
remedies and every covenant and obligation necessary to the exercise thereof by
such separate or co-trustee shall run to and be enforceable by either of them.

      Should any instrument in writing from the Company be required by the
separate or co-trustee so appointed by the Trustee for more fully and certainly
vesting in and confirming to him or it such properties, rights, powers, trusts,
duties and obligations, any and all such instruments in writing shall, on
request, be executed, acknowledged and delivered by the Company at the expense
of the Company; provided, that if an Event of Default shall have occurred and be
continuing, if the Company does not execute any such instrument within fifteen
(15) days after request therefor, the Trustee shall be empowered as an
attorney-in-fact for the Company to execute any such instrument in the Company's
name and stead. In case any separate or co-trustee or a successor to either
shall die, become incapable of acting, resign or be removed, all the estates,
properties, rights, powers, trusts, duties and obligations of such separate or
co-trustee, so far as permitted by law, shall vest in and be exercised by the
Trustee until the appointment of a new trustee or successor to such separate or
co-trustee.

SECTION 5.15       INDIVIDUAL RIGHTS OF TRUSTEE.

      The Trustee in its individual or any other capacity may become the owner
or pledgee of Notes, may make loans to, accept deposits from 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 it must eliminate such conflict within 90
days, apply to the SEC for permission to continue as trustee or resign. Any
agent of the Trustee may do the same with like rights and duties.

                                    ARTICLE 6
                           CONCERNING THE NOTEHOLDERS

SECTION 6.1        EVIDENCE OF ACTION TAKEN BY NOTEHOLDERS.

      Any request, demand, authorization, direction, notice, consent, waiver or
other action provided by this Indenture to be given or taken by Noteholders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Noteholders, in person or by agent duly appointed in
writing, and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are received by the
Trustee. Proof of execution of any instrument or of a writing appointing any
such agent shall be sufficient for any purpose of this Indenture and (subject to
SECTION 5.1 and SECTION 5.2 hereof) conclusive in favor of the Trustee and the
Company, if made in the manner provided in this Article.

                                      44
<Page>

SECTION 6.2        PROOF OF EXECUTION OF INSTRUMENTS AND OF HOLDING OF NOTES
                   RECORD DATE.

      Subject to SECTION 5.1 and SECTION 5.2 hereof, the execution of any
instrument by a Noteholder or his agent or proxy may be provided in accordance
with such reasonable rules and regulations as may be prescribed by the Trustee
or in such manner as shall be satisfactory to the Trustee. The holding of Notes
shall be as provided by the Notes Register or by a certificate of the Registrar
thereof. The Company may set a record date for purposes of determining the
identity of Holders of Notes entitled to vote or consent to any action referred
to in SECTION 6.1 hereof, which record date may be set at any time or from time
to time by written notice to the Trustee for any date or dates (in the case of
any adjournment or resolicitation) not more than 60 days nor less than five days
prior to the proposed date of such vote or consent, and, thereafter,
notwithstanding any other provisions hereof, only Holders of Notes of record on
such record date shall be entitled to so vote or give such consent or to
withdraw such vote or consent.

SECTION 6.3        HOLDERS TO BE TREATED AS OWNERS.

      The Company, the Trustee and any agent of the Company or the Trustee may
deem and treat the Person in whose name any Note shall be registered upon the
Notes Register as the absolute owner of such Note (whether or not such Note
shall be overdue and notwithstanding any notation of ownership or other writing
thereon) for the purpose of receiving payment of or on account of the principal
of, and premium, if any, on and, subject to the provisions of this Indenture,
interest on such Note and for all other purposes, and neither the Company nor
the Trustee nor any agent of the Company or the Trustee shall be affected by any
notice to the contrary. All such payments so made to any such Person, or upon
his order, shall be valid and to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for moneys payable upon any
such Note.

SECTION 6.4        NOTES OWNED BY COMPANY DEEMED NOT OUTSTANDING.

      In determining whether the Holders of the requisite aggregate principal
amount of Notes have concurred in any direction, consent or waiver under this
Indenture, Notes that are owned by the Company or any other obligor on the Notes
or by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the obligor on the Notes shall be
disregarded and deemed not to be Outstanding for the purpose of any such
determination, except that for the purpose of determining whether a Responsible
Officer of the Trustee shall be protected in relying on any such direction,
consent or waiver, only Notes that the Trustee actually knows are so owned shall
be so disregarded. Notes so owned that have been pledged in good faith may be
regarded as Outstanding if the pledgee establishes to the satisfaction of the
Trustee the pledgee's right so to act with respect to such Notes and that the
pledgee is not the Company or any other obligor upon the Notes or any Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any other obligor on the Notes. In case of a
dispute as to such right, the advice of counsel shall be full protection in
respect of any decision made by the Trustee in accordance with such advice. Upon
request of the Trustee, the Company shall furnish to the Trustee promptly an
Officers' Certificate listing and identifying all Notes, if any, known by the
Company to be owned or held by or for the account of any of the above-described
Persons, and, subject to SECTION 5.1 and SECTION 5.2 hereof, the

                                      45
<Page>

Trustee shall be entitled to accept such Officers' Certificate as conclusive
evidence of the facts therein set forth and of the fact that all Notes not
listed therein are Outstanding for the purpose of any such determination.

SECTION 6.5        RIGHT OF REVOCATION OF ACTION TAKEN.

      At any time prior to (but not after) the evidencing to the Trustee, as
provided in SECTION 6.1 hereof, of the taking of any action by the Holders of
the percentage in aggregate principal amount of the Notes specified in this
Indenture in connection with such action, any Holder of a Note the serial number
of which is shown by the evidence to be included among the serial numbers of the
Notes the Holders of which have consented to such action may, by filing written
notice at the Corporate Trust Office and upon proof of holding as provided in
this Article, revoke such action so far as concerns such Note. Except as
aforesaid any such action taken by the Holder of any Note shall be conclusive
and binding upon such Holder and upon all future Holders and owners of such Note
and of any Notes issued in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon any such Note. Any
action taken by the Holders of the percentage in aggregate principal amount of
the Notes specified in this Indenture in connection with such action shall be
conclusively binding upon the Company, the Trustee and the Holders of all such
Notes.

                                    ARTICLE 7
                             SUPPLEMENTAL INDENTURES

SECTION 7.1        SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF NOTEHOLDERS.

      The Company, when authorized by a resolution of its Board of Directors,
and the Trustee may from time to time and at any time enter into an indenture or
indentures supplemental hereto for one or more of the following purposes:

      (a)   to convey, transfer, assign, mortgage or pledge to the Trustee as
security for the Notes any property or assets;

      (b) to evidence the succession of another corporation to the Company, or
successive successions, and the assumption by the successor corporation of the
covenants, agreements and obligations of the Company pursuant to ARTICLE 8
hereof;

      (c) to add to the covenants of the Company such further covenants,
restrictions, conditions or provisions as the Board of Directors shall consider
to be for the protection of the Holders of Notes, and to make the occurrence, or
the occurrence and continuance of a Default in any such additional covenants,
restrictions, conditions or provisions an Event of Default permitting the
enforcement of all or any of the several remedies provided in this Indenture as
herein set forth; PROVIDED that in respect of any such additional covenant,
restriction, condition or provision, such supplemental indenture may provide for
a particular period of grace after default (which period may be shorter or
longer than that allowed in the case of other Defaults) or may provide for
immediate enforcement upon such an Event of Default or may limit the remedies
available to the Trustee due solely to such an Event of Default or may limit the
right of the

                                      46
<Page>

Holders of a majority in aggregate principal amount of the Notes to
waive such an Event of Default;

      (d) to cure any ambiguity or to cure, correct or supplement any defective
provision contained herein or in the Notes, or to make such other provisions in
regard to matters or questions arising under this Indenture or under any
supplemental indenture as the Board of Directors may deem necessary or
desirable, and in any case which the Trustee and the Company shall determine (i)
are not inconsistent with this Indenture and the Notes and (ii) shall not
adversely affect the interests of the Holders of the Notes;

      (e) to modify or supplement this Indenture or any indenture supplemental
hereto in such manner as to permit the qualification thereof under the TIA or
any other similar federal statute hereafter in effect; and

      (f) to permit or facilitate the issuance of Notes pursuant to the
provisions hereof.

      The Trustee is hereby authorized to join in the execution of any such
supplemental Indenture, to make any further appropriate agreements and
stipulations that may be therein continued and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture
that affects the Trustee's own rights, duties, indemnities or immunities under
this Indenture or otherwise.

      Any supplemental indenture authorized by the provisions of this SECTION
7.1 may be executed without the consent of the Holders of any of the Notes at
the time Outstanding, notwithstanding any of the provisions of SECTION 7.2
hereof.

SECTION 7.2 SUPPLEMENTAL INDENTURES WITH CONSENT OF NOTEHOLDERS.

      With the consent (evidenced as provided in ARTICLE 6 hereof) of the
Holders of not less than a majority in aggregate principal amount of the Notes
at the time Outstanding, the Company, when authorized by a resolution of its
Board of Directors, and the Trustee may, from time to time and at any time,
modify this Indenture, any indentures supplemental hereto, the Notes or the
rights of the Holders of the Notes, PROVIDED that no such supplemental indenture
shall (a) change the Stated Maturity of the principal of, or any installment of
principal of or interest on, any Note, or reduce the principal amount thereof,
or reduce the rate or extend the time of payment of interest thereon, or reduce
any amount payable on redemption thereof or impair or affect the right of any
Noteholder to institute suit for the payment thereof or change the place or
currency of payment of principal of, or interest on, any Note, in each case
without the consent of the Holder of each Note so affected, or (b) without the
consent of the Holders of all Notes then Outstanding, (i) reduce the aforesaid
percentage of Notes the consent of the Holders of which is required for any such
modification, or the percentage of Notes the consent of the Holders of which is
required for any waiver provided for in this Indenture, (ii) change any
obligation of the Company to maintain an office or agency in the places and for
the purposes specified in SECTION 2.3 or (iii) make any change in SECTION 4.9 or
this SECTION 7.2, except to increase any percentages or to

                                       47
<Page>

provide that certain other provisions of this Indenture cannot be modified or
waived without the consent of the Holders of each Outstanding Note affected
thereby.

      Upon the request of the Company, accompanied by a copy of a resolution of
the Board of Directors certified by the Secretary or an Assistant Secretary of
the Company authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Noteholders and
other documents, if any, required by SECTION 6.1 hereof, the Trustee shall join
with the Company in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee's own rights, duties, indemnities or
immunities under this Indenture or otherwise, in which case the Trustee may in
its discretion, but shall not be obligated to, enter into such supplemental
indenture.

      It shall not be necessary for the consent of the Noteholders under this
SECTION 7.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

      Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this SECTION 7.2, the
Company shall mail a notice thereof by first class mail to the Holders of Notes
at their addresses as they shall appear on the Notes Register, setting forth in
general terms the substance of such supplemental indenture. Any failure of the
Company to mail such notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such supplemental indenture.

SECTION 7.3 EFFECT OF SUPPLEMENTAL INDENTURE.

      Upon the execution of any supplemental indenture pursuant to the
provisions hereof, this Indenture shall be and be deemed to be modified and
amended in accordance therewith and the respective rights, limitations of
rights, obligations, duties and immunities under this Indenture of the Trustee,
the Company and the Holders of Notes shall thereafter be determined, exercised
and enforced hereunder subject in all respects to such modifications and
amendments, and all the terms and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture
for any and all purposes.

SECTION 7.4 DOCUMENTS TO BE GIVEN TO TRUSTEE.

      The Trustee, subject to the provisions of SECTION 5.1 and SECTION 5.2
hereof, shall receive an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any such supplemental indenture complies with the
applicable provisions of this Indenture and that all conditions precedent to the
execution of such supplemental indenture have been met.

SECTION 7.5 NOTATION OF NOTES IN RESPECT OF SUPPLEMENTAL INDENTURES.

      Notes authenticated and delivered after the execution of any supplemental
indenture pursuant to the provisions of this ARTICLE 7 may bear a notation in
form approved by the Trustee as to any matters provided for by such supplemental
indenture or as to any action taken at any such meeting as the Company shall so
determine, and new Notes so modified as to conform, in the opinion of the
Trustee and the Board of Directors, to any modification of this Indenture

                                       48
<Page>

contained in any such supplemental indenture may be prepared by the Company,
authenticated by the Trustee and delivered in exchange for the Notes then
Outstanding, which Notes so exchanged shall be canceled by the Trustee.

EXCEPT UNDER CERTAIN CONDITIONS.

      (a) The Company shall not merge or consolidate with or into any other
person and the Company shall not sell, lease or convey all or substantially all
of its assets to any person, unless (1) the Company is the continuing
corporation, or the successor corporation or the person that acquires all or
substantially all of the Company's assets is a corporation organized and
existing under the laws of the United States or a State thereof or the District
of Columbia and expressly assumes all the Company's obligations under the Notes
and this Indenture, (2) immediately after such merger, consolidation, sale,
lease or conveyance, there is no Default or Event of Default hereunder, (3) if,
as a result of the merger, consolidation, sale, lease or conveyance, any or all
of the Company's property would become the subject of a lien that would not be
permitted by this Indenture, the Company secures the Notes equally and ratably
with the obligations secured by that lien and (4) the Company delivers or causes
to be delivered to the Trustee an Officers' Certificate and Opinion of Counsel
each stating that the merger, consolidation, sale, lease or conveyance comply
with this Indenture.

pursuant to subsection (a) above, and other than assets required to be sold to
conform with governmental regulations, the Company shall not sell or otherwise
dispose of any assets (other than short-term, readily marketable investments
purchased for cash management purposes with funds not representing the proceeds
of other asset sales) if, on a pro forma basis, the aggregate net book value of
all such sales during the most recent 12-month period would exceed 10 percent of
Consolidated Net Tangible Assets computed as of the end of the most recent
quarter preceding such sale; PROVIDED, HOWEVER, that any such sales shall be
disregarded for purposes of this 10 percent limitation if the proceeds are
invested in assets in similar or related lines of business of the Company and,
provided further, that the Company may sell or otherwise dispose of assets in
excess of such 10 percent limitation if the proceeds from such sales or
dispositions, which are not reinvested as provided above, are retained by the
Company as cash or cash equivalents or are used by the Company to purchase
Notes, which are then delivered to the Trustee for cancellation, or to reduce or
retire Indebtedness ranking pari passu in right of payment to the Notes or
indebtedness of the Company's Subsidiaries.

SECTION 8.2 SUCCESSOR CORPORATION SUBSTITUTED.

      In case of any such merger, consolidation, sale, lease, or transfer, and
following such an assumption by the successor corporation of the Company's
obligations under the Notes and this Indenture, such successor corporation shall
succeed to and be substituted for the Company, with the same effect as if it had
been named herein.

                                       49
<Page>

      Such successor corporation may cause to be signed, and may issue either in
its own name or in the name of the Company prior to such succession, any or all
of the Notes issuable hereunder that theretofore shall not have been signed by
the Company and delivered to the Trustee, and, upon the order of such successor
corporation, instead of the Company, and subject to all the terms, conditions
and limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver any Notes that previously shall have been signed and delivered by
the officers of the Company to the Trustee for authentication and any Notes that
such successor corporation thereafter shall cause to be signed and delivered to
the Trustee for that purpose. All of the Notes so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Notes
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Notes had been issued at the date of the execution hereof.

      In case of any such merger, consolidation, sale, lease or transfer such
changes in phraseology and form (but not in substance) may be made in the Notes
thereafter to be issued as may be appropriate.

      In the event of any such sale or transfer (other than a transfer by way of
lease) the Company or any successor corporation, which shall theretofore have
become such in the manner described in this ARTICLE 8, shall be discharged from
all obligations and covenants under this Indenture and the Notes and may be
liquidated and dissolved.

SECTION 8.3 OPINION OF COUNSEL TO TRUSTEE; OFFICERS' CERTIFICATE.

      The Trustee, subject to the provisions of SECTION 5.1 and SECTION 5.2
hereof, shall receive an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any such merger, consolidation, sale, lease or
transfer, and any such assumption of obligations described in this ARTICLE 8,
and any such liquidation or dissolution described in this ARTICLE 8, complies
with the applicable provisions of this Indenture.

                                    ARTICLE 9

                         OF INDENTURE; UNCLAIMED MONEYS

SECTION 9.1 SATISFACTION AND DISCHARGE OF INDENTURE.

      If at any time (a) the Company shall have paid or caused to be paid the
principal of and premium, if any, and interest on all the Notes Outstanding
hereunder, as and when the same shall have become due and payable, or (b) the
Company shall have delivered to the Trustee for cancellation all Notes
theretofore authenticated (other than any Notes which shall have been destroyed,
lost or stolen and which shall have been replaced or paid as provided in SECTION
2.7 hereof) or (c)(i) all such Notes not theretofore delivered to the Trustee
for cancellation shall have become due and payable, or are by their terms to
become due and payable within one year or are to be called for redemption under
arrangements satisfactory to the Trustee for the giving of notice of redemption,
and (ii) the Company shall have irrevocably deposited or caused to be deposited
with the Trustee as trust funds the entire amount in cash (other than moneys
repaid by the Trustee or any paying agent to the Company in accordance with
SECTION 9.4 hereof) or U.S. Government

                                       50

Obligations, maturing as to principal, premium, if any, and interest in such
amounts and at such times as will insure (without reinvestment) the
availability of cash sufficient, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, to pay at maturity all such Notes not
theretofore delivered to the Trustee for cancellation, including principal,
premium, if any, and interest due or to become due to such date of maturity
as the case may be, and if, in any such case, the Company shall also pay or
cause to be paid all other sums payable hereunder by the Company, then this
Indenture shall cease to be of further effect (except as to (i) rights of
registration of transfer and exchange, and the Company's right to optional
redemption, (ii) substitution of apparently mutilated, defaced, destroyed,
lost or stolen Notes, (iii) rights of Holders to receive payments of
principal of and premium, if any, and interest on, the Notes upon the
original stated due dates therefor (but not upon acceleration), (iv) the
rights and obligations and immunities of the Trustee hereunder, (v) the
rights of the Noteholders as beneficiaries hereof with respect to the
property so deposited with the Trustee payable to all or any of them and (vi)
the maintenance by the Company of its existence), and the Trustee, upon
written demand of the Company accompanied by an Officers' Certificate and an
Opinion of Counsel and at the cost and expense of the Company, shall execute
proper instruments acknowledging such satisfaction of and discharging this
Indenture; PROVIDED that the rights of Holders of the Notes to receive
amounts in respect of principal of and premium, if any, and interest on the
Notes held by them shall not be delayed longer than required by then
applicable mandatory rules or policies of any securities exchange upon which
the Notes are listed.

      The Company shall reimburse the Trustee for any costs or expenses
thereafter reasonably and properly incurred and shall compensate the Trustee for
any services thereafter reasonably and properly rendered by the Trustee in
connection with this Indenture or the Notes.

SECTION 9.2 APPLICATION BY TRUSTEE OF FUNDS DEPOSITED FOR PAYMENT OF NOTES.

      Subject to SECTION 9.4 hereof, all moneys deposited with the Trustee
pursuant to SECTION 9.1 hereof shall be held in trust and applied by it to the
payment, either directly or through any paying agent (including the Company
acting as its own Paying Agent), to the Holders of the particular Notes for the
payment or redemption of which such moneys have been deposited with the Trustee,
of all sums due and to become due thereon for principal, premium, if any, and
interest, but such money need not be segregated from other funds except to the
extent required by law.

SECTION 9.3 REPAYMENT OF MONEYS HELD BY PAYING AGENT.

      In connection with the satisfaction and discharge of this Indenture, all
moneys then held by any Paying Agent under the provisions of this Indenture
shall, upon demand of the Company, be repaid to it or paid to the Trustee and
thereupon such Paying Agent shall be released from all further liability with
respect to such moneys.

SECTION 9.4 RETURN OF MONEYS HELD BY TRUSTEE AND PAYING AGENT UNCLAIMED FOR TWO
YEARS.

                                       51
<Page>

      Any moneys deposited with or paid to the Trustee or any Paying Agent for
the payment of the principal of or premium or interest on any Note and not
applied but remaining unclaimed for two years after the date upon which such
principal, premium or interest shall have become due and payable shall, upon the
written request of the Company, be repaid to the Company by the Trustee or such
Paying Agent, and the Holder of such Note shall, unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
laws, thereafter look only to the Company for any payment which such Holder may
be entitled to collect, and all liability of the Trustee or any Paying Agent
with respect to such moneys shall thereupon cease.

SECTION 9.5 DEFEASANCE AND DISCHARGE OF INDENTURE.

      The Company will be deemed to have paid and will be discharged from any
and all obligations in respect of the Notes on the 123rd day after the deposit
referred to in subparagraph (A) below has been made, and the provisions of this
Indenture will no longer be in effect with respect to the Notes (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except as to (a) rights of registration of transfer and
exchange, and the Company's right of optional redemption, (b) substitution of
apparently mutilated, defaced, destroyed, lost or stolen securities, (c) rights

existence; PROVIDED that the following conditions shall have been satisfied:

                  (A) with reference to this SECTION 9.5, the Company has
            irrevocably deposited or caused to be irrevocably deposited with the
            Trustee (or another trustee satisfying the requirements of SECTION
            5.8 hereof) as trust funds in trust, specifically pledged as
            security for, and dedicated solely to, the benefit of the Holders of
            the Notes, (i) money in an amount, (ii) U.S. Government Obligations,
            which through the payment of interest and principal in respect
            thereof in accordance with their terms (without reinvestment), will
            provide not later than one day before the due date of any payment
            referred to in clause (x) or (y) of this subparagraph (A) money in
            an amount, or (iii) a combination thereof, sufficient, in the
            opinion of a nationally recognized firm of independent public
            accountants expressed in a written certification thereof delivered
            to the Trustee, to pay and discharge, after payment of all federal,
            state and local taxes or other charges and assessments in respect
            thereof, (x) the principal of, premium, if any, and each installment
            of principal and interest on the Outstanding Notes at the maturity
            date of such principal or installment of principal or interest and
            (y) any mandatory sinking fund payments or analogous payments
            applicable to the Notes on the day on which such payments are due

                  (B) the Company has delivered to the Trustee (i) an Opinion of
            Counsel to the effect that Holders will not recognize income, gain
            or loss for

                                       52
<Page>

            federal income tax purposes as a result of the Company's exercise
            of its option under this SECTION 9.5 and will be subject to
            federal income tax on the same amount and in the same manner and
            at the same times as would have been the case if such deposit,
            defeasance and discharge had not occurred, which Opinion of
            Counsel must be based on (x) a change in applicable federal
            income tax law or related Treasury Regulations after the date of
            this Indenture or (y) a ruling of the Internal Revenue Service to
            the same effect and (ii) an Opinion of Counsel to the effect that
            the defeasance trust does not constitute an "investment company"
            under the Investment Company Act of 1940, as amended, and after
            the passage of 123 days following the deposit, the trust fund
            will not be subject to the effect of Section 547 of the U.S.
            Bankruptcy Code or Section 15 of the New York Debtor and Creditor
            Law;

            Default or Event of Default shall have occurred and be continuing on
            the date of such deposit or during the period ending on the 123rd
            day after the date of such deposit, and such deposit shall not
            result in a breach or violation of, or constitute a default under,
            any other agreement or to which the Company is a party or by which
            the Company is bound; and

                  (D) if at such time the Notes are listed on a national
            securities exchange, the Company has delivered to the Trustee an
            Opinion of Counsel to the effect that the Notes will not be delisted
            as a result of such deposit, defeasance and discharge.

SECTION 9.6 DEFEASANCE OF CERTAIN OBLIGATIONS.

            the Notes, (i) money in an amount, (ii) U.S. Government Obligations,
            which through the payment of interest and principal in respect
            thereof in accordance with their terms (without reinvestment), will
            provide not later than one day before the due date of any payment
            referred to in clauses (x) or (y) of this SECTION 9.6, money in an
            amount, or (iii) a combination thereof, sufficient, in the opinion
            of a nationally recognized firm of independent public accountants
            expressed in a certification thereof delivered to the Trustee, to
            pay and discharge, after payment of all federal, state and local
            taxes or other charges and assessments in respect thereof, (x) the

            mandatory sinking fund payments or analogous payments applicable to
            the Notes on the day on which such payments are due and payable in
            accordance with the terms of this Indenture and the Notes;

                  (B) the Company has delivered to the Trustee (i) an Opinion of
            Counsel to the effect that Holders will not recognize income, gain
            or loss for federal income tax purposes as a result of the Company's
            exercise of its option under this SECTION 9.6 and will be subject to
            federal income tax on the same amount and in the same manner and at
            the same times as would have been the case if such deposit,
            defeasance and discharge had not occurred, and (ii) an Opinion of
            Counsel to the effect that the defeasance trust does not constitute
            an "investment company" under the Investment Company Act of 1940, as
            amended, and after the passage of 123 days following the deposit,
            the trust fund will not be subject to the effect of Section 547 of
            the U.S. Bankruptcy Code or Section 15 of the New York Debtor and

            of Default, or event that after the giving of notice or lapse of
            time or both would become an Event of Default, shall have occurred
            and be continuing on the date of such deposit or during the period
            ending on the 123rd day after the date of such deposit, and such
            deposit shall not result in a breach or violation of or constitute a
            default under any other agreement or instrument to which the Company
            is a party or by which the Company is bound; and

                  (D) if at such time the Notes are listed on a national
            securities exchange, the Company has delivered to the Trustee an
            Opinion of Counsel to the effect that the Notes will not be delisted

                               REDEMPTION OF NOTES

SECTION 10.1 OPTIONAL REDEMPTION.

      The Company at its option may, at any time, redeem the Notes, in whole or
in part, upon payment of a redemption price equal to (A) the greater of (i) 100%
of the principal amount of the Notes to be redeemed and (ii) the sum of present
values of the Remaining Scheduled Payments on the Notes being redeemed
discounted to the date of redemption on a semiannual basis (assuming a 360-day
year consisting of twelve 30-day months) at a rate equal to the Treasury Rate
plus 75 basis points, plus, in either case, (B) accrued and unpaid interest, if
any, on the principal amount of Notes being redeemed to the redemption date.

SECTION 10.2 NOTES REDEEMED IN PART.

                                       54
<Page>

      Upon surrender of a Note that is redeemed in part, the Company shall issue
and the Trustee shall authenticate for the Holder at the expense of the Company
a new Note equal in principal amount to the unredeemed portion of the Note
surrendered.

SECTION 10.3 NOTICE OF REDEMPTION.

      Notice of redemption to the Holders of Notes to be redeemed shall be given
by the Company by mailing notice of such redemption by first class mail, postage
prepaid, at least 30 days and not more than 60 days prior to the date fixed for
redemption to such Holders of Notes at their last addresses as they shall appear
in the Notes Register. Failure to give notice by mail, or any defect in the
notice to the Holder of any Note designated for redemption as a whole or in part
shall not affect the validity of the proceedings for the redemption of any other
Note.

      The notice of redemption to each Holder shall specify that the Notes are
being redeemed pursuant to this ARTICLE 10, the date fixed for redemption, the
place or places of payment, the CUSIP and ISIN numbers (as applicable) of the
Notes being redeemed, that payment will be made upon presentation and surrender
of the Notes, that interest accrued to the date fixed for redemption will be
paid as specified in this Article and that, on and after said date, interest
thereon or on the portions thereof redeemed will cease to accrue.

      Any notice of redemption of Notes to be redeemed at the option of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company. If notice of redemption
is to be given by the Trustee in the name of the Company, the Company will, at
least 40 calendar days prior to the date fixed for redemption, notify the
Trustee of such redemption date and of the principal amount of Notes to be
redeemed.

      At least one Business Day prior to the redemption date specified in the
notice of redemption given as provided in this SECTION 10.3, the Company shall
deposit with the Trustee or with one or more paying agents (or, if the Company
is acting as its own paying agent, set aside, segregate and hold in trust as
provided in SECTION 2.4 hereof) an amount of money sufficient to redeem on the
redemption date all the Notes so called for redemption.

SECTION 10.4 NOTES SELECTED FOR REDEMPTION.

      If less than all of the Notes are to be redeemed or purchased in an offer
to purchase at any time, the Trustee shall select the Notes to be redeemed or
purchased among the Holders of the Notes in compliance with the requirements of
the principal national securities exchange, if any, on which the Notes are
listed or, if the Notes are not so listed, on a PRO RATA basis, by lot or in
accordance with any other method the Trustee considers fair and appropriate. In
the event of partial redemption by lot, the particular Notes to be redeemed
shall be selected, unless otherwise provided herein, not less than 30 nor more
than 60 days prior to the redemption date by the Trustee from the outstanding
Notes not previously called for redemption.

      The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of $1,000 or

                                       55
<Page>

whole multiples of $1,000; except that if all of the Notes of a Holder are to
be redeemed, the entire outstanding amount of Notes held by such Holder, even
if not a multiple of $1,000, shall be redeemed. Except as provided in the
preceding sentence, provisions of this Indenture that apply to Notes called
for redemption also apply to portions of Notes called for redemption.

SECTION 10.5 PAYMENT OF NOTES CALLED FOR REDEMPTION.

      If notice of redemption has been given as above provided, the Notes shall
become due and payable on the date and at the place stated in such notice at the
redemption price, and on and after said date (unless the Company shall default
in the payment of such Notes at the redemption price) interest on the Notes or
portions of Notes so called for redemption shall cease to accrue and, except as
provided in SECTION 5.5 and SECTION 9.4 hereof, such Notes shall cease from and
after the date fixed for redemption to be entitled to any benefit or security
under this Indenture, and the Holders thereof shall have no right in respect of
such Notes except the right to receive the redemption price thereof. On
presentation and surrender of such Notes at a place of payment specified in said
notice, said Notes shall be paid and redeemed by the Company at the redemption
price, PROVIDED that any semiannual payment of interest becoming due on the date
fixed for redemption shall be payable to the Holders of such Notes registered as
such on the relevant record date subject to the terms and provisions of SECTION
2.6(i) hereof.

      If the Company defaults in the payment of the redemption price with
respect to any Note called for redemption, upon surrender thereof for
redemption, the principal shall, until paid or duly provided for, bear interest
from the date fixed for redemption at the rate borne by the Note.

                            MISCELLANEOUS PROVISIONS

SECTION 11.1 INCORPORATORS, SHAREHOLDERS, OFFICERS, DIRECTORS AND EMPLOYEES OF
COMPANY EXEMPT FROM INDIVIDUAL LIABILITY.

      No recourse under or upon any obligation, covenant or agreement contained
in this Indenture, or in any Note, or because of any indebtedness evidenced
thereby, shall be had against any incorporator, as such, or against any past,
present or future shareholder, officer, director or employee, as such, of the
Company or of any successor, either directly or through the Company or any
successor, under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of the Notes by the Holders thereof and as part of the consideration
for the issue of the Notes.

SECTION 11.2 PROVISIONS OF THE INDENTURE FOR THE SOLE BENEFIT OF PARTIES AND
NOTEHOLDERS.

      Nothing in this Indenture or in the Notes, expressed or implied, shall
give or be construed to give to any Person, other than the parties hereto and
their successors and the Holders (and, where expressly set forth herein, owners
of interests in any Global Note), any legal or equitable right, remedy or claim
under this Indenture or under any covenant or provision herein contained, all
such covenants and provisions being for the sole benefit of the parties hereto
and their

                                       56
<Page>

successors and the Holders (and, where expressly set forth herein,
owners of interests in any Global Note).

SECTION 11.3  SUCCESSORS AND ASSIGNS OF COMPANY BOUND BY INDENTURE.

      All the covenants, stipulations, promises and agreements in this Indenture
contained by or on behalf of the Company shall bind its successors and assigns,
whether so expressed or not.

SECTION 11.4  NOTICES AND DEMANDS ON COMPANY, TRUSTEE AND NOTEHOLDERS.

      Any notice or demand which by any provision of this Indenture is required
or permitted to be given or served by the Trustee or by the Holders to or on the
Company may be given or served by being deposited postage prepaid, first-class
mail (except as otherwise specifically provided herein) addressed (until another
address of the Company is filed by the Company with the Trustee) to Edison
Mission Energy, 18101 Von Karman Avenue, Suite 1700, Irvine, California 92612,
Attention: Chief Financial Officer. Any notice, direction, request or demand by
the Company or any Noteholder to or upon the Trustee shall be deemed to have
been sufficiently given or made, for all purposes, if given or made at the
Corporate Trust Office.

      Where this Indenture provides for notice to Holders, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder entitled thereto, at his
last address as it appears in the Notes Register. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

      In case, by reason of the suspension of or irregularities in regular mail
service, it shall be impracticable to mail notice to the Company and Noteholders
when such notice is required to be given pursuant to any provision of this
Indenture, then any manner of giving such notice as shall be satisfactory to the
Trustee shall be deemed to be a sufficient giving of such notice. All notices
and other communications delivered hereunder shall be deemed effective upon
receipt.

SECTION 11.5  STATEMENTS TO BE CONTAINED IN OFFICERS' CERTIFICATES AND OPINIONS

THE INDENTURE]

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

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

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

      1. INTEREST. Edison Mission Energy, a California corporation (the
"Company"), promises to pay interest on the principal amount of this Note at 10%
per annum from August 10, 2001 until maturity. The Company will pay interest
semi-annually in arrears on February 15 and August 15 of each year (each an
"Interest Payment Date"); PROVIDED that if any such day is not a Business Day,
then such payment will be made on the next succeeding Business Day. Interest on
this Note will accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from August 10, 2001; 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 in respect of this Note shall be February 15, 2002. The Company
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time at a
rate that is equal to the rate set forth on the face of this Note; it shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace periods) from time to time at the same rate to the extent
lawful. Interest will be computed on the basis of a 360-day year consisting of
twelve 30-day months. If a Reporting Cessation occurs, the interest rate
applicable to the Notes shall be increased by 0.50% per annum from the date such
Reporting Cessation occurs until such time as the Reporting Cessation has ended.

      2. METHOD OF PAYMENT. The Company will pay interest on this Note (except
defaulted interest) to the Person who is the registered Holder of this Note at
the close of business on the February 1 or August 1 next preceding the Interest
Payment Date, even if this Note is canceled after such record date and on or
before such Interest Payment Date, except as provided in Section 2.11 of the
Indenture with respect to defaulted interest. This Note will be payable as to
principal, premium, if any, and interest by mailing a check for such to or upon
the written order of the registered Holder of this Note entitled thereto at its
last address as it appears on the Notes Register or, upon written application to
the Trustee by a Holder of $1,000,000 or more in aggregate principal amount of
Notes, by wire transfer of immediately available funds to an account maintained
by such Holder with a bank or other financial institution. Such payment shall 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.

                                      A-2

<Page>

      3. PAYING AGENT AND REGISTRAR. Initially, The Bank of New York, 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 this Note under an Indenture, dated as of
August 10, 2001, between the Company and the Trustee (as the same may be
amended, modified and supplemented, the "Indenture"). The terms of this Note
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections
77aaa-77bbbb). This Note is 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.

      5. REDEMPTION. The Company at its option may, at any time, redeem the
Notes, in whole or in part, upon payment of a redemption price equal to (A) the
greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii)
the sum of present values of the Remaining Scheduled Payments on the Notes being
redeemed discounted to the date of redemption on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at a rate equal to the Treasury
Rate plus 75 basis points, plus, in either case, (B) accrued and unpaid
interest, if any, on the principal amount of Notes being redeemed to the
redemption date.

      6. 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 last registered address. Subject to payment by
the Company of a sum sufficient to pay the amount due on redemption, interest on
the Notes ceases to accrue upon the date duly fixed for redemption of the Notes.

      7. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are issuable only in
registered form without coupons in denominations of $100,000 and any integral
multiple of $1,000 in excess thereof. 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.

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

      9. AMENDMENT, SUPPLEMENT. With the consent of the Holders of not less than
a majority in aggregate principal amount of the Notes (including Additional
Notes, if any) at the time Outstanding, evidenced as provided in the Indenture,
the Indenture or any supplemental indentures or the rights of the Holders of the
Notes may be modified by the Company and the Trustee; PROVIDED that no such
modification shall (a) change the Stated Maturity of the principal of, or any
installment of principal of or interest on, any Note, or reduce the principal
amount

                                      A-3

<Page>

thereof, or reduce the rate or extend the time of payment of interest
thereon, or reduce any amount payable on the redemption thereof or impair or
affect the rights of any Noteholder to institute suit for the payment thereof or
change the place or currency of payment of principal of, or interest on, any
Note, in each case without the consent of the Holder of each Note so affected,
or (b) without the consent of the Holders of all Notes then outstanding, (i)
reduce the aforesaid percentage of Notes the consent of the Holders of which is
required for any such modification, or the percentage of Notes the consent of
Holders of which is required for any waiver provided for in the Indenture, (ii)
change any obligation of the Company to maintain an office or agency for payment
of and transfer and exchange of the Notes or (iii) make certain changes to
provisions relating to the waiver of past defaults or to the provisions for
supplementing the Indenture with the consent of the Holders.

      10. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest on the Notes; (ii) default in payment
when due of principal of or premium, if any, on the Notes when the same becomes
due and payable at maturity, upon redemption or otherwise, (iii) failure by the
Company for 90 days after notice to the Company by the Trustee or the Holders of
at least 25% in principal amount of the Notes (including Additional Notes) then
outstanding voting as a single class to comply with certain other agreements in
the Indenture or the Notes; (iv) default under certain other agreements relating
to Indebtedness of the Company which default results in the acceleration of such
Indebtedness prior to its express maturity; (v) certain final judgments for the
payment of money that remain undischarged for a period of 90 days; and (vi)
certain events of bankruptcy or insolvency with respect to the Company. If any
Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the then outstanding Notes may declare the
principal of all the Notes and the interest accrued thereon to be due and
payable immediately. 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 without further action or notice. Holders may
not enforce the Indenture or the Notes except as provided in the Indenture. The
Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any past Default or Event of Default except a Default in the payment
of principal of, premium, if any, or interest on, any 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.

      11. 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.

      12. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder of the Company, as such, shall not have any
liability for any obligations of the Company under the Notes, the Indenture or
any indenture supplemental thereto 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.

                                      A-4

      13. AUTHENTICATION. This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

      14. 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).

      15. 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 shall have all the rights set forth in the Registration Rights Agreement
dated as of August 10, 2001, between the Company and the parties named on the
signature pages thereof or, in the case of Additional Notes, Holders of
Restricted Global Notes and Restricted Definitive Notes shall have the rights
set forth in one or more registration rights agreements, if any, between the
Company and the other parties thereto, relating to rights given by the Company
to the purchasers of any Additional Notes (collectively, the "Registration
Rights Agreement").

      16. 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.

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

            (ii) (A) any purchase of the Notes by us will be for our own account
         or for the account of one or more other Institutional Accredited

         sole investment discretion or (B) we are a "bank," within the meaning

        Notes may be offered, resold, pledged or otherwise transferred only (i)
        in the United States to a person who we reasonably believe is a
        "qualified institutional buyer"(as defined in Rule 144A under the
        Securities Act) in a transaction meeting the requirements of Rule 144A,
        (ii) outside the United States in a transaction in accordance with Rule

        Act, in each of cases (i) through (iv), in accordance with any
        applicable securities laws of any state of the United States or any
        other applicable jurisdiction. We understand that the registrar and
        transfer agent for the Notes will not be required to accept for
        registration of transfer any Notes acquired by us, except upon
        presentation of evidence satisfactory to the Company and the transfer
        agent that the foregoing restrictions on transfer have been complied
        with. We further understand that any Notes acquired by us will be in the
        form of definitive physical certificates and will bear a legend
        reflecting the substance of this paragraph.

            We acknowledge that you, the Company and others will rely upon our
         confirmations, acknowledgements and agreements set forth herein, and we
         agree to notify you promptly in writing if any of our representations

            (a)   Unless the Company determines in good faith that the
Exchange Offer shall not be permissible under applicable law or Commission
policy, the Company shall prepare and cause to be filed with the Commission
as soon as reasonably practicable after the Closing Date, subject to Sections
2(b) and 2(c) of this Agreement, a Registration Statement (an "EXCHANGE OFFER
REGISTRATION STATEMENT") for an offer to exchange (an "EXCHANGE OFFER") the
Registrable Notes (subject to Section 2(c)) for a like aggregate principal
amount of debt securities of the Company in all material respects
substantially identical to the Initial Notes (the "EXCHANGE NOTES") (and
which are entitled to the benefits of the Indenture, which shall be qualified
under the TIA in connection with such registration, or a trust indenture
which is substantially identical in all material respects to the Indenture),
other than (i) such changes to the Indenture or any such substantially

connection with the Trustee's rights and duties or to comply with any
requirements of the Commission to effect or maintain the qualification
thereof under the TIA and (ii) such changes relating to restrictions on
transfer set forth in the Indenture.  The Exchange Offer shall be registered
under the Securities Act on the appropriate form of Registration Statement
and shall comply with all applicable tender offer rules and regulations under
the Exchange Act and with all other applicable laws.  Subject to the terms
and limitations of Section 2(c), such Exchange Offer Registration Statement
may also cover any resales of Exchange Notes by any Restricted Person, in the
manner or manners designated by them which, in any event, is reasonably
acceptable to the Company.

Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Exchange
Offer, it being the objective of such Exchange Offer to enable each holder of
Registrable Notes electing to exchange the Initial Notes for Exchange Notes
(assuming that such holder is not an affiliate of the Company within the
meaning of the Securities Act, acquires the Exchange Notes in the ordinary
course of such holder's business and has no arrangements with any person to
participate in the distribution of the Exchange Notes and is not prohibited
by any law or policy of the Commission from participating in the Exchange
Offer) to trade such Exchange Notes 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.

                                       5
<Page>

The Company shall use its reasonable best efforts to (i) cause the Exchange
Offer Registration Statement to become effective under the Securities Act on
or prior to the Effective Date, (ii) keep the Exchange Offer open for a
period of not less than the shorter of (A) the period ending when the last
remaining Initial Note is tendered into the Exchange Offer and (B) 30 days
from the date notice is mailed to the holders of Initial Notes (PROVIDED that
in no event shall such period be less than the period required under
applicable Federal and state securities laws) and (iii) maintain such
Exchange Offer Registration Statement continuously effective for a period
(the "EXCHANGE PERIOD") of not less than the longer of (A) the period until
the consummation of the Exchange Offer and (B) 120 days after effectiveness
of the Exchange Offer Registration Statement, PROVIDED HOWEVER, that in the
event that all resales of Exchange Notes (including, subject to the time
periods set forth herein, any Resale Notes and including, subject to the time
periods set forth herein, any resales by broker-dealers that receive Exchange
Notes for their own account pursuant to the Exchange Offer) covered by such
Exchange Offer Registration Statement have been made, the Exchange Offer
Registration Statement need not remain continuously effective for the period
set forth in clause (B) above.  The Company shall make the Prospectus
contained in the Exchange Offer Registration Statement and any amendment or
supplement thereto available to any broker-dealer for use in connection with
any resale of any Exchange Notes for a period of not less than 120 days after
the consummation of the Exchange Offer.  Upon consummation of the Exchange
Offer, the Company shall deliver to the Trustee under the Indenture for
cancellation all Initial Notes tendered by the holders thereof pursuant to
the Exchange Offer and not withdrawn prior to the date of consummation of the
Exchange Offer.  Each Restricted Person shall notify the Company promptly
after reselling all Resale Notes held by such Restricted Person which are
covered by any such Registration Statement.

Each holder of Registrable Notes to be exchanged in the Exchange Offer (other
than any Restricted Person) shall be required as a condition to participating
in the Exchange Offer to represent that (i) it is not an Affiliate of the
Company, (ii) any Exchange Notes to be received by it shall be acquired in
the ordinary course of its business, (iii) that at the time of the
consummation of the Exchange Offer it shall have no arrangement with any
person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Notes and (iv) if such holder is a
broker-dealer, that it will receive Exchange Notes for its own account in
exchange for Initial Notes 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 Notes.  Upon consummation of an Exchange Offer in accordance
with this Section 2 and compliance with the other provisions of this Section
2, the Company shall, subject to Sections 2(b) and 2(c), have no further
obligation to register Registrable Notes pursuant to Section 3(a) of this
Agreement; PROVIDED that the other provisions of this Agreement shall
continue to apply as set forth in such provisions.

            (b)   In the event that the Company reasonably determines in good
faith that (i) the Exchange Notes would not, upon receipt in the Exchange
Offer by any holder of Registrable Notes (other than any Restricted Person
and other than any holder who is not acquiring such Exchange Notes in the
ordinary course of business or who has an arrangement with any person to
participate in the distribution of such Exchange Notes), be tradeable by each
holder thereof without restriction under the Securities Act and the Exchange
Act and without restriction under applicable blue sky or state securities
laws, (ii) after conferring with counsel, the Commission is unlikely to
permit the Exchange Offer Registration Statement to become effective prior to
the Effective Date (except in the circumstances set forth in Section 2(c)) or
(iii) the Exchange Offer

                                       6
<Page>

may not be made in compliance with applicable laws, then the Company shall
promptly deliver notice thereof (the "SHELF NOTICE") to the holders of the
Registrable Notes and the Trustee and shall thereafter file an Initial Shelf
Registration Statement pursuant to, and otherwise comply with, the provisions
of Section 3(a).  Following the delivery of a Shelf Notice in accordance with
this Section 2(b) and compliance with Section 3(a), the Company shall not
have any further obligation under this Section 2.

            (c)   In the event that the Company reasonably determines in good
faith that (i) the Exchange Notes would not, upon consummation of any resale
thereof by a Restricted Person to any Person other than another Restricted
Person, be tradeable by each holder thereof without restriction under the
Securities Act (other than applicable prospectus requirements) and the
Exchange Act and without restriction under applicable blue sky or state
securities laws or (ii) the Commission is unlikely to permit the Exchange
Offer Registration Statement to become effective prior to the Effective Date
solely because such Registration Statement covers resales of the Exchange
Notes by Restricted Persons, then the Company shall promptly deliver a Shelf
Notice to the Restricted Persons who are holders of Registrable Notes and to
the Trustee, and the Company shall thereafter file an Initial Shelf
Registration Statement with respect to any such Registrable Notes pursuant
to, and otherwise comply with, the provisions of Section 3(a); PROVIDED that
such Initial Shelf Registration Statement shall only cover resales of
Registrable Notes by Restricted Persons if a Shelf Notice is not then
otherwise required to be delivered pursuant to Section 2(b); and, PROVIDED,
FURTHER that such Initial Shelf Registration Statement covering Registrable
Notes held by Restricted Persons shall be kept effective for at least a
period of 120 days and is not required to remain effective with respect to
Registrable Notes held by Restricted Persons thereafter.  Following the
delivery of a Shelf Notice in accordance with this Section 2(c) and
compliance with Section 3(a), the Company shall not have any further
obligation under this Section 2 with respect to the filing of an offer to
exchange the Registrable Notes held by the Restricted Persons (including,
without limitation, any obligation to provide that an Exchange Offer
Registration Statement filed pursuant to Section 2(a) cover resales of
Exchange Notes by Restricted Persons); PROVIDED that the provisions of this
Section 2 shall otherwise remain in full force and effect with respect to
Registrable Notes held by any person other than a Restricted Person.

            SECTION 3.   SHELF REGISTRATION; REGISTRABLE NOTES.  With respect
to the Registrable Notes, if a Shelf Notice is delivered in accordance with
Section 2(b) or 2(c) of this Agreement, then the Company shall comply with
the following provisions of this Section 3:

            (a)   INITIAL SHELF REGISTRATION.  The Company shall prepare and
cause to be filed with the Commission a Registration Statement for an
offering to be made on a continuous basis other than pursuant to an
Underwritten Offer pursuant to Rule 415 covering all of the Registrable Notes
(or, if a Shelf Notice is delivered solely pursuant to Section 2(c), all of
the Registrable Notes held by any Restricted Persons) (the "INITIAL SHELF
REGISTRATION STATEMENT"); PROVIDED, HOWEVER, that no holder shall be entitled
to have its Registrable Notes covered by such Initial Shelf Registration
Statement unless such holder agrees in writing, within 10 Business Days after
actual receipt of a request therefrom, to be bound by all the provisions of
this Agreement applicable to such holder.  No holder shall be entitled to the
benefits of Section 4 of this Agreement unless and until such holder shall
have provided all information reasonably requested by the Company (after
conferring with counsel), and such holder shall not be entitled

                                       7
<Page>

to such benefits with respect to any period during which such information was
not provided.  Each holder to which any Shelf Registration Statement is being
effected agrees to furnish promptly to the Company all information required
to be disclosed in order to make the information previously furnished to the
Company by such holder not materially misleading.  The Initial Shelf
Registration Statement shall be an appropriate form permitting registration
of such Registrable Notes for resale by the holders thereof in the manner or
manners reasonably designated by them (but excluding any Underwritten
Offerings).  The Company shall use its reasonable best efforts to (A) cause
the Initial Shelf Registration Statement to be declared effective under the
Securities Act on or prior to the Effective Date and (B) keep the Initial
Shelf Registration Statement continuously effective under the Securities Act
for a period of two years after the Closing Date (subject to extension
pursuant to the last paragraph of Section 5 and subject, with respect to
Registrable Notes held by Restricted Persons, to the limitations set forth in
Section 2(c)) (such two-year period, as it may be extended, being the
"EFFECTIVE PERIOD"), or such shorter period ending when (1) all Registrable
Notes covered by the Initial Shelf Registration Statement have been sold or
(2) a Subsequent Shelf Registration Statement covering all of such
Registrable Notes remaining unsold has been declared effective under the
Securities Act or (3) all Registrable Notes may be sold pursuant to
subsection (k) of Rule 144.

Notwithstanding any other provision hereof, the Company may postpone or
suspend the filing or the effectiveness of a Registration Statement (or any
amendments or supplements thereto), if (1) such action is required by
applicable law, or (2) such action is taken by the Company in good faith and
for valid business reasons (not including avoidance of such party's
obligations hereunder), including the acquisition or divestiture of assets,
other pending corporate developments, public filings with the Commission or
other similar events, so long as the Company promptly thereafter complies
with the requirements of Section 5(b) hereof, if applicable.  Notwithstanding
the occurrence of any event referred to in the immediately preceding sentence
(a "SUSPENSION"), such event shall not suspend, postpone or in any other
manner affect the running of the time period after which an Illiquidity Event
shall be deemed to occur and, if the filing or effectiveness of a
Registration Statement is postponed or suspended as a result of a Suspension,
an Illiquidity Event shall nonetheless exist if all other requirements set
forth for the occurrence of an Illiquidity Event shall be satisfied, and the
provisions of Section 4 requiring the accrual payment of additional interest,
as set forth in such Section, on the Registrable Notes, shall be applicable.

            (b)   SUBSEQUENT SHELF REGISTRATIONS.  If the Initial Shelf
Registration Statement or any Subsequent Shelf Registration Statement ceases
to be effective for any reason at any time during the Effective Period after
the Effective Date, the Company may attempt to obtain the withdrawal of any
order suspending the effectiveness thereof, and may amend such Initial Shelf
Registration Statement or Subsequent Shelf Registration Statement in a manner
reasonably expected to obtain the withdrawal of the order suspending the
effectiveness thereof, or file an additional "shelf" Registration Statement
applicable to the Initial Notes pursuant to Rule 415 covering all of such
Registrable Notes remaining unsold (a "SUBSEQUENT SHELF REGISTRATION
STATEMENT").  If a Subsequent Shelf Registration Statement is declared
effective, the Company shall use its reasonable best efforts to keep such
Shelf Registration Statement continuously effective for a period after the
date of such effectiveness equal in length to the length of the Effective
Period plus the aggregate number of days from the date of the order
suspending the effectiveness of the Initial Shelf Registration Statement or
any Subsequent Shelf Registration

                                       8
<Page>

Statement to the date of the effectiveness of the Subsequent Shelf
Registration Statement.  As used herein, the term "SHELF REGISTRATION
STATEMENT" means the Initial Shelf Registration Statement and any Subsequent
Shelf Registration Statement.

            SECTION 4.  ADDITIONAL INTEREST FOR ILLIQUIDITY.

            (a)   The Company acknowledges and agrees that the Initial
Purchasers (and any subsequent holders of the Initial Notes) have acquired
the Initial Notes in reliance on the covenant of the Company to use its
reasonable best efforts to (i) cause to become effective on or prior to the
Effective Date (A) the Exchange Offer Registration Statement or (B) an
Initial Shelf Registration Statement, and (ii) maintain the respective
effectiveness of such Registration Statements as described herein.  The
Company further acknowledges and agrees that the failure of the Company to
fulfill such covenants will have an adverse effect on the holders of the
Initial Notes.  Therefore, the Company agrees that from and after the date on
which any Illiquidity Event occurs, additional interest (in addition to the
interest otherwise payable with respect to the Registrable Notes) shall
accrue with respect to the Initial Notes until but not including the date on
which such Illiquidity Event shall cease to exist (and provided no other
Illiquidity Event with respect to any Initial Notes shall then be
continuing), at the rate of one half of one percent (0.50%) per annum, which
additional interest shall be payable by the Company to the holders of all
Initial Notes at the times, in the manner and subject to the same terms and
conditions set forth in the Indenture, as nearly as may be, as though the
interest rates provided in such Initial Notes had been increased by one half
of one percent (0.50%) per annum.  Subject to the provisions of this
Section 4, the Company agrees that it shall be liable to the holders of all
Initial Notes for the payment of any and all additional interest on the
Initial Notes that shall accrue pursuant to this Section 4.

Any such additional interest accrued on any such Initial Notes but unpaid on
the date on which such interest ceases to accrue (the "CURE DATE") shall be
due and payable on the first interest payment date following the next record
date following such Cure Date (or the record date occurring on such Cure
Date, if such Cure Date is a record date) to the holders of record of such
Initial Notes on such record date.

            (b)   The Company shall promptly notify the holders of the
Initial Notes and the Trustee of the occurrence of any Illiquidity Event of
which it has knowledge.

Notwithstanding the foregoing, the Company shall not be required to pay the
additional interest described in clause (a) of this Section 4 to a holder
with respect to the Registrable Notes held by such holder if the applicable
Illiquidity Event arises by reason of the failure of such holder to provide
such information as (i) the Company may reasonably request, with reasonable
prior written notice, for use in the Shelf Registration Statement or any
Prospectus included therein to the extent the Company reasonably determines
that such information is required to be included therein by applicable law,
(ii) the NASD or the Commission may request in connection with such Shelf
Registration Statement, or (iii) is required to comply with the agreements of
such holder contained in clause (a) of Section 3 to the extent compliance
thereof is necessary for the Shelf Registration Statement to be declared
effective.

            SECTION 5.  REGISTRATION PROCEDURES.  In connection with the
registration of any Registrable Notes or Exchange Notes pursuant to Sections
2 and 3 hereof, the Company shall use

                                       9
<Page>

its reasonable best efforts to effect such registration to permit the sale of
such Registrable Notes or Exchange Notes in accordance with any permitted
intended method or methods of disposition thereof, and pursuant thereto the
Company shall:

            (a)   prepare and cause to be filed with the Commission a
Registration Statement or Registration Statements as prescribed by Sections 2
and 3 of this Agreement, and use its reasonable best efforts to cause each
such Registration Statement to become effective and remain effective for the
applicable period as provided herein; PROVIDED, HOWEVER, that (i) during the
period in which the Initial Registration Statement is open for the Restricted
Persons, the Company shall afford any Restricted Person which is a holder of
Registrable Notes or Exchange Notes and the Special Counsel, upon such
holder's written request to the Company, an opportunity to review copies of
all such documents proposed to be filed, and (ii) if such filing is pursuant
to Section 3, before filing any Registration Statement or Prospectus or any
amendments or supplements thereto (including documents that would be
incorporated therein by reference after the initial filing of the
Registration Statement), the Company shall afford the Special Counsel for all
holders of the Registrable Notes covered by such Registration Statement an
opportunity to review copies of all such documents proposed to be filed;

            (b)   prepare and cause to be filed with the Commission such
amendments and post-effective amendments to each Shelf Registration Statement
as may be necessary to keep such Registration Statement continuously
effective for the applicable period as provided herein; cause the related
Prospectus to be supplemented by any required Prospectus supplement, and as
so supplemented to be filed pursuant to Rule 424 (or any similar provisions
then in force) under the Securities Act; and comply with the provisions of
the Securities Act, the Exchange Act and the rules and regulations of the
Commission promulgated thereunder with respect to the disposition of all
securities covered by such Registration Statement as so amended or in such
Prospectus as so supplemented in accordance with the intended methods of
disposition by the sellers of Registrable Notes covered thereby set forth
therein;

            (c)   if a Shelf Registration Statement is filed pursuant to
Section 3 hereof, notify the selling holders of Registrable Notes promptly
after the Company becomes aware thereof, and confirm such notice in writing,
(i) when a Prospectus or any Prospectus supplement or post-effective
amendment has been filed, and, with respect to a Registration Statement or
any post-effective amendment, when the same has become effective, (ii) of any
request by the Commission for amendments or supplements to the Registration
Statement or the Prospectus or for additional information, (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of
a Registration Statement or of any order preventing or suspending the use of
any preliminary prospectus or Prospectus or the initiation of any proceedings
for that purpose, (iv) of the receipt by the Company of any notification with
respect to the suspension of the qualification or exemption from
qualification of a Registration Statement or any of the Registrable Notes for
offer or sale in any jurisdiction, or the initiation of any proceeding for
such purpose, (v) of the existence of any fact known to the Company which
results in such Registration Statement or related Prospectus or any document
incorporated therein by reference containing any untrue statement of a
material fact or omitting 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, not misleading (which notice may be
accompanied by an instruction that such notice constitutes material
non-public information and to suspend the use of

                                       10
<Page>

the Prospectus until the requisite changes have been made, and which
instruction shall require that such holders shall not communicate such
material non-public information to any third party and shall not sell or
purchase, or offer to sell or purchase, any securities of the Company after
receipt of such notice) and (vi) if the Company reasonably determines that
the filing of a post-effective amendment to such Registration Statement would
be appropriate;

            (d) if a Shelf Registration Statement is filed pursuant to
Section 3, use its reasonable efforts to prevent the issuance of any order
suspending the effectiveness of a Registration Statement or of any order
preventing or suspending the use of a Prospectus or suspending the
qualification (or exemption from qualification) of any of the Registrable
Notes for sale in any jurisdiction and, if any such order is issued, to
obtain the withdrawal of any such order at the earliest possible moment;

            (e) if a Shelf Registration Statement is filed pursuant to
Section 3, furnish to each selling holder of Registrable Notes who so
requests (at such holder's address set forth in the Securities Register)
without charge, one conformed copy of the Registration Statement or
Registration Statements and each post-effective amendment thereto, including
financial statements and schedules, all documents incorporated therein by
reference and all exhibits (including those incorporated by reference);

            (f) if a Shelf Registration Statement is filed pursuant to
Section 3, deliver to each selling holder of Registrable Notes without
charge, as many copies of the Prospectus (including each preliminary
prospectus) and each amendment or supplement thereto as such persons may
reasonably request; and, subject to the last paragraph of this Section 5, the
Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the selling holders of Registrable Notes and
the underwriters, if any, in connection with the offering and sale of the
Registrable Notes covered by such Prospectus and any amendment or supplement
thereto;

            (g) prior to any public offering of Registrable Notes, register
or qualify, or cooperate with the selling holders of Registrable Notes, the
underwriters, if any, and their respective counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Notes for offer and sale under the
securities or blue sky laws of such jurisdictions within the United States as
the selling holders reasonably request in writing (provided that, if
Registrable Notes are offered other than through an Underwritten Offering,
the Company agrees to cause its counsel to perform blue sky investigations
and file registrations and qualifications required to be filed pursuant to
this Section 5(g)); keep each such registration or qualification (or
exemption therefrom) effective during the period such Registration Statement
is required to be kept effective; and do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Notes covered by the applicable Registration Statement; provided,
however, that the Company will not be required to qualify as a foreign
corporation, or to do business, to file a general consent or take any action
which would subject it to service of process in any jurisdiction or take any
action which would subject itself to taxation in any such jurisdiction;

            (h) if a Shelf Registration Statement is filed pursuant to
Section 3, cooperate with the Trustee and the selling holders of Registrable
Notes to facilitate the timely preparation

                                       11
<Page>

and delivery of certificates representing Registrable Notes to be sold, which
certificates shall not bear any restrictive legends and shall be in a form
eligible for deposit with The Depository Trust Company, and enable such
Registrable Notes to be in such authorized denominations and registered in
such names as the holders may reasonably request at least three Business Days
prior to any such sale;

            (i) if a Shelf Registration Statement is filed pursuant to
Section 3, upon the occurrence of any event contemplated by Section 5(c),
prepare a supplement or post-effective amendment to the Registration
Statement or a supplement to the related Prospectus or any document
incorporated therein by reference or file any other required document so
that, as thereafter delivered to the purchasers of the Registrable Notes,
such Prospectus will not contain an untrue statement of a material fact or
omit to state a material fact necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.  If
the Company so notifies the holders to suspend the use of the Prospectus
after the occurrence of such an event, the holders shall suspend use of the
Prospectus, and not communicate such material non-public information to any
third party, and not sell or purchase, or offer to sell or purchase, any
securities of the Company, until the Company has amended or supplemented the
Prospectus to correct such misstatement or omission;

            (j) use its reasonable best efforts to cause the Registrable
Notes covered by the Registration Statement to continue to be rated by the
rating agencies that initially rated the Initial Notes during the period that
the Registration Statement is required hereunder to remain effective (it
being acknowledged, however, that the foregoing shall not be deemed to
require the Company to maintain the rating of such Registrable Notes at the
rating given to the Initial Notes);

            (k) prior to the effective date of the first Registration
Statement relating to the Registrable Notes or the Exchange Notes, as the
case may be, (i) provide the Trustee with printed certificates for such
securities in definitive form or in a global form eligible for deposit with
The Depository Trust Company and (ii) provide a CUSIP number for such
Registrable Notes or Exchange Notes represented by such certificates;

            (l) if a Shelf Registration Statement is filed pursuant to
Section 3, enter into such reasonably required agreements and take all other
appropriate actions in order to expedite or facilitate the registration or
the disposition of such Registrable Notes;

            (m) in the event of any Underwritten Offering (which shall only
be undertaken at the option of the Company), if a Shelf Registration
Statement is filed pursuant to Section 3, make available prior to the filing
thereof for inspection by a representative of the holders of a majority in
aggregate principal amount of the Registrable Notes being sold, and the
Special Counsel, on the one hand, or underwriter on the other hand
(collectively, the "INSPECTORS"), during reasonable business hours, all
financial and other records, pertinent corporate documents and properties of
the Company (collectively, the "RECORDS"), and cause the officers, directors
and employees of the Company to supply all relevant information as shall be
reasonably necessary to enable them to exercise any applicable due diligence
responsibilities; PROVIDED, HOWEVER, that, as a condition to supplying such
information, the Company shall receive an agreement in writing from the
Special Counsel agreeing that any information that is designated in writing
by the

                                       12
<Page>

Company, in good faith, as confidential at the time of delivery of such
information shall be kept confidential by such Inspector (other than as to
holders of Registrable Notes) and by any holders of Registrable Notes
receiving such information, unless (i) disclosure of such information is
required pursuant to applicable law or by court or administrative order, (ii)
disclosure of such information is, in the reasonable opinion of counsel to
the Company, necessary to avoid or correct a misstatement or omission of a
material fact in the Registration Statement, Prospectus or any supplement or
post-effective amendment thereto or disclosure is otherwise required by law,
(iii) such information becomes generally available to the public other than
as a result of a disclosure by any Inspector or any such holder of
Registrable Notes in violation of this Section 5(m) or (iv) such information
is approved for release by the Company, in writing;

            (n) use its best efforts to cause the Indenture or the trust
indenture provided for in Section 2, as the case may be, to be qualified
under the TIA not later than the effective date of such Registration
Statement; and, in connection therewith, cooperate with the Trustee under the
Indenture and the holders of the Registrable Notes to effect such changes to
the Indenture as may be required for the Indenture to be so qualified in
accordance with the terms of the TIA and execute, and use its best efforts to
cause such Trustee to execute, all documents as may be required to effect
such changes, and all other forms and documents required to be filed with the
Commission to enable the Indenture or the trust indenture provided for in
Section 2 to be so qualified in a timely manner;

            (o) otherwise use its reasonable best efforts to comply with all
applicable rules and regulations of the Commission.

For purposes of the covenants set forth in this Section 5, references to a
Shelf Registration Statement, including a Shelf Registration Statement filed
pursuant to Section 3, shall be deemed to include any Registration Statement,
filed pursuant to Section 2, which covers, for the period set forth therein,
resales of Exchange Notes held by Restricted Persons as provided in Section
2, and, in connection with such resales such Restricted Persons shall be
entitled to exercise all rights, receive all notices and copies of documents,
and otherwise receive all benefits afforded to sellers or holders of
Registrable Notes under this Section 5 in connection with a Shelf
Registration Statement.  Without limiting the generality of the foregoing,
the Company agrees to fulfill its obligations set forth in Sections 5(a),
(b), (c), (d), (e), (f), (h), (i), (l) and (m) with respect to any such
Registration Statement filed pursuant to Section 2 insofar as it covers such
resales.

The Company may require each seller of Registrable Notes as to which any
registration is being effected, as a condition thereto, to furnish to the
Company such information regarding the holder and the distribution of such
Registrable Notes as the Company may, from time to time, request in writing,
including without limitation stating (i) that it is not an Affiliate of the
Company, (ii) the amount of Registrable Notes held by such holder prior to
the Exchange Offer, (iii) the amount of Registrable Notes owned by such
holder to be exchanged in the Exchange Offer, and representing that such
holder is not engaged in, and does not intend to engage in, and has no
arrangement or understanding with any Person to participate in, a
distribution of the Exchange Notes to be issued, and (iv) that it is
acquiring the Exchange Notes in its ordinary course of business, and to
covenant and agree to promptly notify the Company if any such information so
provided by such seller ceases to be true and correct and will promptly
thereafter furnish the

                                       13
<Page>

Company with corrected information.  The Company may exclude from such
registration the Registrable Notes of any Person who fails to furnish such
information within a reasonable time after receiving such request.

Each holder of Registrable Notes agrees by acquisition of such Registrable
Notes that, upon receipt of any notice from the Company of the happening of
any event of the kind described in Section 5(c)(ii), 5(c)(iii), 5(c)(v) or
5(c)(vi) hereof, such holder shall forthwith discontinue disposition of such
Registrable Notes covered by such Registration Statement or Prospectus until
such holder is advised in writing (the "ADVICE") by the Company that the use
of the applicable Prospectus may be resumed, and has received copies of any
amendments or supplements thereto and, if so directed by the Company, such
holder will deliver to the Company (at such holder's expense) all copies in
its possession, other than permanent file copies then in such holder's
possession, of the prospectus covering such Registrable Notes current at the
time of receipt of such notice, or certify in writing as to the destruction
thereof.  In the event the Company shall give any such notice, the length of
the Effective Period shall be extended by the number of days during such
period from and including the date of the giving of such notice to and
including the date when each seller of Registrable Notes covered by such
Registration Statement shall have received (x) the copies of the supplemented
or amended Prospectus contemplated by Section 5(i) or (y) the Advice.

            SECTION 6. DELIVERY OF PROSPECTUS; NOTIFICATION UPON RESALE. The
Initial Purchasers acknowledge that it is the position of the staff of the
Commission that any broker-dealer that receives Exchange Notes for its own
account in exchange for Registrable Notes pursuant to the Exchange Offer must
deliver a prospectus in connection with any resale of such Resale Notes.  By
so acknowledging, such Initial Purchasers shall not be deemed to admit that,
by delivering a prospectus, it is an underwriter within the meaning of the
Securities Act.

Each Initial Purchaser shall notify the Company promptly upon the completion
of the resale of the Resale Notes received by such Initial Purchaser pursuant
to the Exchange Offer.

            SECTION 7. REGISTRATION EXPENSES.  The Company shall bear all
expenses incurred in connection with the performance of its obligations under
Sections 2, 3 and 4; PROVIDED, HOWEVER, that the Company shall bear or
reimburse the holders for the reasonable fees and disbursements of only one
counsel, the Special Counsel, in accordance with the terms of the Purchase
Agreement; PROVIDED, FURTHER, HOWEVER, that if the Company opts for an
Underwritten Offering, the Company shall not be responsible for any fees and
expenses of any underwriter, including any underwriting discounts and
commissions or any legal fees and expenses of counsel to the underwriters
(except for the reasonable fees and disbursements of counsel in connection
with state securities or blue sky qualification of any of the Registrable
Notes or the Exchange Notes).

            SECTION 8. INDEMNIFICATION AND CONTRIBUTION.

            (a) The Company agrees to (A) indemnify and hold harmless each
holder of Registrable Notes (including any Initial Purchaser which holds
Registrable Notes, including Resale Notes, for its own account (each, a
"RESALE INITIAL PURCHASER") and each Person, if any, who controls any such
Person within the meaning of either the Securities Act or the Exchange Act
and each director, officer, employee or agent of each such Person) (each a
"HOLDER INDEMNIFIED PARTY") against any and all losses, claims, damages or
liabilities, joint or several, to

                                       14
<Page>

which they or any of them are subject under the Securities Act, the Exchange
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in any
Registration Statement covering Registrable Notes held by such person or any
Prospectus relating to any such Registration Statement, or any amendment
thereof or supplement thereto and all documents incorporated by reference
therein, or arise out of or are based upon the omission or alleged omission
to state therein a material fact necessary in order to make the statements
therein, in light of the circumstances in which they were made, not
misleading, and (B) reimburse each such Holder Indemnified Party for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action
as such expenses are incurred; PROVIDED, HOWEVER, that the Company will not
be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any such untrue statement or alleged
untrue statement or omission or alleged omission made in such Registration
Statement or Prospectus, or in any amendment thereof or supplement thereto,
in reliance upon and in conformity with written information relating to such
holder provided by such holder to the Company specifically for use therein
(collectively, the "HOLDER INFORMATION"); PROVIDED, FURTHER, HOWEVER, that
the indemnity obligations arising out of this Section 8 with respect to any
untrue statement or alleged untrue statement or omission or alleged omission
made in any preliminary Prospectus shall not inure to the benefit of any
holder or any controlling Person of such holder, to the extent that a
Prospectus relating to such Registrable Notes or the Exchange Notes, as the
case may be, was required to be delivered by such holder under the Securities
Act in connection with such sale and any such loss, claim, damage or
liability of such holder results from the fact that such holder failed to
send or deliver to the Person asserting any such losses a copy of the final
Prospectus with or prior to the delivery of the written confirmation of the
sale of the Registrable Notes or the Exchange Notes, as the case may be, and
such final Prospectus would have cured the untrue statement or omission
giving rise to such losses if the Company had previously furnished copies
thereof to such holder.  This indemnity agreement will be in addition to any
liability which the Company may otherwise have.

            (b) As a condition to the inclusion of a holder's Registrable
Notes in a Registration Statement, such holder shall agree to (i) indemnify
and hold harmless the Company and each person who controls the Company within
the meaning of either the Securities Act or the Exchange Act, and each
director, officer, employee or agent of each such person, against any and all
losses, claims, damages or liabilities, joint or several, to which they or
any of them are subject under the Securities Act, the Exchange Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in a Registration
Statement covering Registrable Notes held by such holder or any Prospectus
relating to any such Registration Statement or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact necessary in order to make the
statements therein, in light of the circumstances in which they were made,
not misleading, and (ii) reimburse each such indemnified party for any legal
or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action
as such expenses are incurred; in each and every case under clause (i) and
(ii) above to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in such
Registration Statement or Prospectus or in any amendment

                                       15
<Page>

thereof or supplement thereto, in reliance upon and in conformity with the
Holder Information.  This indemnity agreement will be in addition to any
liability which any such holder may otherwise have.  In no event shall the
liability of any selling holder of Registrable Notes hereunder be greater in
amount than the dollar amount of the proceeds (net of payment of all
expenses) received by such holder upon the sale (or, in the case of Resale
Notes, the resale) of the Registrable Notes giving rise to such
indemnification obligation.

            (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying
party under this Section 8, notify the indemnifying party in writing of the
commencement thereof (enclosing a copy of all papers served); but the
omission to so notify the indemnifying party (i) shall not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did
not otherwise learn of such action and such omission results in the
forfeiture by the indemnifying party or material impairment of substantial
rights and defenses and (ii) shall not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than
the indemnification obligations provided in paragraph (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 shall 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.  After notice from the indemnifying party to such indemnified party of
its election to so assume the defense of such claim or action, the
indemnifying party will not be liable to such indemnified party under this
Section 8 for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than costs of
investigation; provided that if (i) the defendants in any such action include
both the indemnified party and the indemnifying party, and the indemnified
party shall have received an opinion of counsel reasonably acceptable to the
indemnifying party that representation of both parties by the same counsel
would be inappropriate due to actual or likely conflicts of interest between
them, or (ii) the indemnifying party shall not have employed counsel for the
indemnified party to represent the indemnified party within a reasonable time
after notice of the institution of such action, then the indemnified party or
parties shall have the right to select one firm of separate counsel (in
addition to the fees and expenses of local counsel) to assert any separate
legal defenses and to otherwise defend such action on behalf of such
indemnified party or parties.  No indemnifying party shall be liable for any
settlement of any action or claim for monetary damages which an indemnified
party may effect without the written consent of the indemnifying party, which
consent shall not be unreasonably withheld.

            (d) If the indemnification provided for in Section 8(a) or (b)
hereof is for any reason, other than as specified in such provisions,
unavailable to or insufficient to hold harmless an indemnified party, then
each indemnifying party shall contribute to the aggregate losses, claims,
damages or liabilities (or actions in respect thereof) referred to in Section
8(a) or (b) hereof in such proportion as is appropriate to reflect the
relative fault and benefits to the Company on the one hand and such holders
on the other hand in connection with the statements or omissions which
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 Company and such holders shall be determined by
reference to, among other things, the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent any untrue

                                       16
<Page>

statement or omission.  The obligations of the holders in this Section 8(d)
are several in proportion to their respective obligations hereunder and not
joint.  Notwithstanding the provisions of this Section 8(d), in no event
shall any holder of Registrable Notes be required to contribute any amount
which is in excess of (i) the aggregate principal amount of Initial Notes
sold or exchanged by such holder less (ii) the amount of any damages that
such person has otherwise been required to pay by reason of such alleged
untrue statement or 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 Section 8, each Holder
Indemnified Party shall have the same rights to contribution as a holder, and
each person who controls the Company within the meaning of either the
Securities Act or the Exchange Act and each officer, director, employee and
agent of such person, shall have the same rights to contribution as the
Company, subject in each case to the applicable terms and conditions of this
Section 8(d).  Any party entitled to contribution will, promptly after
receipt of notice of commencement of any action, suit or proceeding against
such party in respect of which a claim for contribution may be made against
another party or parties under this Section 8(d), notify such party or
parties from whom contribution may be sought; but the omission to so notify
such party or parties (x) shall not relieve the party or parties from whom
contribution may be sought from any liability under this paragraph (d) unless
and to the extent it did not otherwise learn of such action and such omission
results in the forfeiture by the party or parties from whom contribution may
be sought or material impairment of substantial rights and defenses and (y)
shall not, in any event, relieve such party or parties from any obligations
other than under this Section 8(d).

            (e) The provisions of this Section 8 will remain in full force
and effect, regardless of any investigation made by or on behalf of any
holder of Registrable Notes, the Initial Purchasers, the Company or any of
the officers, directors or controlling persons referred to in this Section 8
and will survive the sale (or, in the case of Resale Notes, the resale) by a
holder of Registrable Notes of such Registrable Notes.

                                       17
<Page>

            SECTION 9. UNDERWRITTEN REGISTRATIONS (IF ANY).  No holder may
participate in any Underwritten Registration, which Underwritten Registration
shall only be undertaken at the option of the Company, unless such holder (a)
agrees to sell such holder's Initial Notes on the basis provided in any
underwriting arrangements approved by the persons entitled hereunder to
approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements.

            SECTION 10. TERMINATION. In the event that no Initial Notes are
sold to the Initial Purchasers pursuant to the Purchase Agreement, this
Agreement shall automatically terminate, without liability on the part of any
party.  Upon the fulfillment of all obligations on the part of the Company to
register the Initial Notes as set forth herein (including maintaining the
effectiveness of any applicable Registration Statements), this Agreement
shall terminate; provided that the provisions of Sections 7 and 8 hereof
shall survive any termination and remain in full force and effect.

            SECTION 11. MISCELLANEOUS.

            (a) NO INCONSISTENT AGREEMENTS.  The Company neither has, as of
the date hereof, entered into, nor shall, on or after the date hereof, enter
into, any agreement with respect to its securities that is inconsistent with
the rights granted to the holders of Registrable Notes herein or otherwise
conflicts with the provisions hereof.

            (b) AMENDMENTS AND WAIVERS.  The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions
hereof may not be given, unless the Company has obtained the written consent
of holders of at least a majority of the then outstanding aggregate principal
amount of the Registrable Notes (or, after the consummation of any Exchange
Offer in accordance with Section 2, of Exchange Notes); PROVIDED that, with
respect to any matter that directly or indirectly affects the rights of any
Restricted Person hereunder occurring within the period in which the Initial
Registration Statement is open for the Restricted Persons, the Company shall
obtain the written consent of each such Restricted Person against which such
amendment, modification, supplement, waiver or consent is to be effective.
Notwithstanding the foregoing (except for the foregoing proviso), a waiver or
consent to departure from the provisions hereof with respect to a matter that
relates exclusively to the rights of holders of Registrable Notes whose
securities are being sold or exchanged pursuant to a Registration Statement
and that does not directly or indirectly affect the rights of other holders
of Registrable Notes may be given by holders of at least a majority in
aggregate principal amount of the Registrable Notes being sold or exchanged
by such holders pursuant to such Registration Statement; PROVIDED, HOWEVER,
that the provisions of this sentence may not be amended, modified or
supplemented except in accordance with the provisions of the immediately
preceding sentence.  Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Resale Initial Purchasers and that does not
directly or indirectly affect the rights of holders of Registrable Notes or
Exchange Notes may be given by each of the Resale Initial Purchasers affected
thereby.

      respect to the Initial Purchasers, at the address set forth in the
      Purchase Agreement and thereafter at the address for such holders of
      Registrable Notes set forth in the Security Register applicable to such
      Registrable Notes; and

            (ii) if to the Company, initially at the address set forth in
      the Purchase Agreement and thereafter at such other address, notice of

telecopied.

Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the Trustee at the
address specified in the Indenture.

            (d) SUCCESSORS AND ASSIGNS.  This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the
parties hereto, including, without limitation and without the need for an
express assignment or any consent by the Company thereto, subsequent holders
of Registrable Notes.

            (e) COUNTERPARTS.  This Agreement may be executed in any number
of counterparts and by the parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement.

            (f) HEADINGS.  The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

            (g) GOVERNING LAW.  This Agreement and the rights and duties of
the parties hereunder shall be governed by, and construed in accordance with,
the laws of the State of New York.  Each of the parties hereto hereby submits
to the non-exclusive jurisdiction of the Federal and State Courts of the
Borough of Manhattan in the City of New York in any suit or proceeding
arising out of or relating to this Agreement or the transactions contemplated
hereby.

            (h) SEVERABILITY.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstances,
is held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way
impaired or affected thereby, it being intended that all of the rights and
privileges of the parties shall be enforceable to the fullest extent
permitted by law.
