     charge payable in connection therewith (other than any such transfer taxes
     or similar governmental charge payable upon exchange or transfer pursuant
     to Sections 2.10, 7.5 and 11.1 hereof).
        -------------  ---     ----

          (iii) The Registrar shall not be required to register the transfer 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

     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

     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 2.3 hereof.

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

     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 2.8 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.

                                       24
<PAGE>

     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 2.10.  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 2.11.  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

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 2.12.  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, 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

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

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

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

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

                                       29
<PAGE>

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 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

                                       30
<PAGE>

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,
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

                                       31

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.

compensation to the Trustee and each predecessor Trustee and their respective

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;

     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,

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 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

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

              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

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 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.

-----------
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

                                       34
<PAGE>

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.

     Notwithstanding any other provision of this Indenture (including, without
limitation, Section 4.6 hereof), the right of any Holder to receive, and to

              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.

     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

                                       35
<PAGE>

          (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, if there shall be reasonable ground for believing that the
repayment of such funds or indemnity reasonably satisfactory to it against such
liability is not reasonably assured to it.

     request therefor by the Company or by any such Noteholder; or

          (iii) the Trustee shall become incapable of acting, or shall be

     Trustee or of its property shall be appointed, or any public officer shall

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

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
                                                                  -----------

                                       40

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,
                                                                 ------------

benefit of the retiring Trustee.

Section 5.11.  Merger, Conversion, Consolidation or Succession to Business of
               Trustee.

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.

     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.

                          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.

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

                                       42
<PAGE>

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 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.

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

     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

       --------
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

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

waiver provided for in this Indenture, (ii) change any obligation of the Company

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.

of Columbia and expressly assumes all the Company's obligations under the Notes

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

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

for cancellation, or to reduce or retire Indebtedness ranking pari passu in

Section 8.2.  Successor Corporation Substituted.

     In case of any such merger, consolidation, sale, lease, or transfer, and

corporation, instead of the Company, and subject to all the terms, conditions
and limitations in this Indenture prescribed, the Trustee shall authenticate and

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

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
                                            ---------

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 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.

Section 11.5.  Statements to Be Contained in Officers' Certificates and Opinions
               of Counsel.

     Upon any application or demand by the Company to the Trustee to take any
action under any of the provisions of this Indenture, the Company shall furnish
to the Trustee an Officers' Certificate stating that all conditions precedent
provided for in this Indenture relating to the proposed action have been
complied with and an Opinion of Counsel stating that in the opinion of such
counsel all such conditions precedent have been complied with, except that in
the case of any such application or demand as to which the furnishing of such
documents is specifically required by any provision of this Indenture relating
to such particular application or demand, no additional certificate or opinion
need be furnished.

     Each certificate or opinion provided for in this Indenture and delivered to
the Trustee with respect to compliance with a condition or covenant provided for
in this Indenture shall include (a) a statement that the Person making such
certificate or opinion has read such covenant or condition, (b) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based, (c) a statement that, in the opinion of such Person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or

                                       54
<PAGE>

condition has been complied with and (d) a statement as to whether or not, in
the opinion of such Person, such condition or covenant has been complied with.

     Any certificate, statement or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of
or representations by counsel, unless such officer knows that the certificate or
opinion or representations with respect to the matters upon which his
certificate, statement or opinion may be based as aforesaid are erroneous, or in
the exercise of reasonable care should know that the same are erroneous.  Any
certificate, statement or Opinion of Counsel may be based, insofar as it relates
to factual matters (information with respect to which is in the possession of
the Company) upon the certificate, statement or opinion of or representations by
an officer or officers of the Company, unless such counsel knows that the
certificate, statement or opinion or representations with respect to the matters
upon which his certificate, statement or opinion may be based as aforesaid are
erroneous, or in the exercise of reasonable care should know that the same are
erroneous.

     Any certificate, statement or opinion of an officer of the Company or of
counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Company, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

     Any certificate or opinion of any independent firm of public accountants
filed with the Trustee shall contain a statement that such firm is independent.

Section 11.6.  Payments Due on Saturdays, Sundays and Holidays.

     If the date of maturity of interest on or principal, or premium, if any, of
the Notes or the date fixed for redemption of any Note shall not be a Business
Day, then payment of interest, principal, or premium need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.

     1.   Interest.  Edison Mission Energy, a California corporation (the
"Company"), promises to pay interest on the principal amount of this Note at
___% per annum from ________________, ____ until maturity.  The Company will pay
interest semi-annually in arrears on ___________ and ___________ of each year,

interest has been paid or, if no interest has been paid, from ___________;
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 _____________, ____.  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.

     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 ___________ or ___________ next preceding the
Interest Payment Date, even if this Note is canceled after such record date and

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.

     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

                                      A-2
<PAGE>

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 June 28, 1999 (the "Original Indenture"), between the Company and the
Trustee, as supplemented by the [   ] Supplemental Indenture, dated as of
____________ (the "[   ]  Supplemental Indenture"), between the Company and the
Trustee (the Original Indenture, as so supplemented, and as the same may be
amended, modified and further 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 (S)(S)
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.  The Notes are
unsecured obligations of the Company, and the series of Notes of which this Note
is a part is limited to $___ million in aggregate principal amount.

     5.   Redemption.

     [Insert relevant provisions if the series of Notes is redeemable pursuant
to the applicable Supplemental Indenture]

     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 of this series are
issuable only in registered form without coupons in denominations of $_______
and any integral multiple of $_____ 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 at the time
Outstanding, evidenced as in the Indenture provided, the Indenture or any
supplemental indentures or the rights of the Holders of the Notes may be
modified; 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 thereof, or reduce the rate or extend
the time of payment of interest thereon,

                                      A-3
<PAGE>

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 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).

as to the accuracy of such numbers either as printed on the Notes or as

other identification numbers placed thereon.
