               In any case where several matters are required to be certified

such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly

action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and

instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and

                                     -44-
<PAGE>

date of the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other manner which the
Trustee deems sufficient.

               (c) The ownership of Securities shall be proved by the Security
Register.

               (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made
upon such Security.

               (e) The Company may set any day as a record date for the purpose
of determining the Holders of Outstanding Securities entitled to give, make or
take any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders of Securities; provided, that the Company may not set a record date
                          --------
for, and the provisions of this paragraph shall not apply with respect to, the
giving or making of any notice, declaration, request or direction referred to in
the next paragraph. If not set by the Company prior to the first solicitation of
a Holder made by any Person in respect of any such matter referred to in the
foregoing sentence, the record date for any such matter shall be the 30th day
(or, if later, the date of the most recent list of Holders required to be
provided pursuant to Section 701) prior to such first solicitation. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to take
the relevant action, whether or not such Holders remain Holders after such
record date; provided, that no such action shall be effective hereunder unless
             --------
taken on or prior to the applicable Expiration Date by Holders of the requisite
principal amount of Outstanding Securities on such record date. Nothing in this
paragraph shall be construed to prevent the Company from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be canceled

                                     -45-
<PAGE>

and of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder of Securities in the manner set forth in Section 106.

               The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration
referred to in Section 502, (iii) any request to institute proceedings referred
to in Section 507(2) or (iv) any direction referred to in Section 512. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities on such record date, and no other Holders, shall be entitled to join
in such notice, declaration, request or direction, whether or not such Holders
remain Holders after such record date; provided, that no such action shall be
                                       --------
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities on such
record date. Nothing in this paragraph shall be construed to prevent the Trustee
from setting a new record date for any action for which a record date has
previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person be canceled
and of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Trustee, at the Company's
expense, shall cause notice of such record date, the proposed action by Holders
and the applicable Expiration Date to be given to the Company in writing and to
each Holder of Securities in the manner set forth in Section 106.

               With respect to any record date set pursuant to this Section 104,
the party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided, that no such change shall be effective unless
                      --------
notice of the proposed new Expiration Date

                                     -46-
<PAGE>

is given to the other party hereto in writing, and to each Holder of Securities
in the manner set forth in Section 106, on or prior to the existing Expiration
Date. If an Expiration Date is not designated with respect to any record date
set pursuant to this Section, the party hereto which set such record date shall
be deemed to have initially designated the 180th day after such record date as
the Expiration Date with respect thereto, subject to its right to change the
Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no
Expiration Date shall be later than the 180th day after the applicable record
date.

               (f) Without limiting the foregoing, a Holder entitled hereunder
to take any action hereunder with regard to any particular Security may do so
with regard to all or any part of the principal amount of such Security or by
one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such principal amount.

SECTION 105.       Notices, Etc., to Trustee and Company.
                   -------------------------------------

               Any request, demand, authorization, direction, notice, consent,
waiver or Act of Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with:

               (1) the Trustee by any Holder or by the Company shall be
          sufficient for every purpose hereunder if made, given, furnished or
          filed in writing to or with the Trustee at its Corporate Trust Office,
          Attention: Corporate Trust Administration; or

               (2) the Company by the Trustee or by any Holder shall be
          sufficient for every purpose hereunder (unless otherwise herein
          expressly provided) if in writing and mailed, first-class postage
          prepaid, to the Company addressed to it at the address of its
          principal office specified in the first paragraph of this Indenture,
          Attention: Corporate Secretary, or at any other address previously
          furnished in writing to the Trustee by the Company.

SECTION 106.      Notice to Holders; Waiver.
                  -------------------------

               Where this Indenture provides for notice to Holders of any event,
such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at his address as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice. 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 regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 107.      Application of Trust Indenture Act.
                  ----------------------------------

               The Trust Indenture Act shall apply as a matter of contract to

                                Security Forms

SECTION 201.      Forms Generally.
                  ---------------

          The Securities and the Trustee's certificates of authentication shall
be in substantially the forms set forth in this Article, with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture, and may have such letters, numbers or other marks
of identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Securities,
as evidenced by their execution of the Securities.

          The definitive Securities shall be printed, lithographed or engraved
or produced by any combination of these methods on steel engraved borders or may
be produced in any other manner all as determined by the officers executing such
Securities, as evidenced by their execution of such Securities.

          Upon their original issuance, Rule 144A Securities shall be issued in
the form of one or more Global Securities without interest coupons registered in
the name of DTC, as Depositary, or its nominee and deposited with the Trustee,

                                     -50-
<PAGE>

as custodian for DTC, in New York, New York, for credit by DTC to the respective
accounts of beneficial owners of the Securities represented thereby (or such
other accounts as they may direct). Such Global Securities, together with their
Successor Securities which are Global Securities other than the Regulation S
Global Security are collectively herein called the "Restricted Global Security."

          Upon their original issuance, Regulation S Securities shall be issued
in the form of a Regulation S Temporary Global Security without coupons
registered in the name of DTC, as Depositary, or its nominee and deposited with
the Trustee, as custodian for DTC, for credit to Euroclear, as operator of
Euroclear system, and Clearstream to the respective accounts of beneficial
owners of the Securities represented thereby (or such other accounts as they may
direct) in accordance with the rules thereof. Beneficial interests in the
Regulation S Temporary Global Security may only be held through Euroclear and
Clearstream until such interests are exchanged for corresponding interests in a
Regulation S Permanent Global Security as provided in the next sentence. A
holder of a beneficial interest in the Regulation S Temporary Global Security
must provide written certification in the form set forth in Annex D to Euroclear
or Clearstream, as the case may be, that the beneficial owner of the interest in
such Global Security is not a U.S. Person (an "Owner Securities Certification"),
and Euroclear or Clearstream, as the case may be, must provide to the Trustee a
similar certificate in the form set forth in Annex E (a "Depositary Securities
Certification"), prior to (i) the payment of interest with respect to such
holder's beneficial interest in the Regulation S Temporary Global Security and
(ii) any exchange of such beneficial interest for a beneficial interest in a
Regulation S Permanent Global Security.

          Following the termination of the Restricted Period, beneficial
interests in the Regulation S Temporary Global Security shall be exchanged for
beneficial interests in Regulation S Permanent Global Securities pursuant to the
Applicable Procedures. Upon receipt of Annex E, the Company shall deliver to the
Trustee and the Trustee shall authenticate a Regulation S Permanent Global
Security, which shall be in principal amount equal to the principal amount of
the Securities referred to in Annex E and the Trustee shall reduce on its
records the principal amount of the Regulation S Temporary Global Security in an
amount equal to

                                     -51-
<PAGE>

such principal amount. Regulation S Temporary Global Securities, together with
their successor Regulation S Permanent Global Securities, are collectively
herein called the "Regulation S Global Security."

commencing January 15, 2002, at the rate of 13.50% per annum until the principal
hereof is paid or made available for payment; PROVIDED, HOWEVER, that if (i) the
Company has not filed a registration statement (the "Exchange Registration
Statement") under the Securities Act of 1933, as amended (the "Securities Act"),
registering a security substantially identical to this Security (except that
such Security will not contain terms with respect to the Liquidated Damages (as
defined below) payments described below or transfer restrictions) pursuant to an
exchange offer (the "Exchange Offer") or a registration statement registering
this Security for resale (a "Resale Registration Statement") in each case within

Agreement) without being succeeded promptly by an additional registration
statement filed and declared effective, in each case (i) through (iv) upon the
terms and conditions set forth in the Registration Rights Agreement (each such
event referred to in Clauses (i) through (iv), a "Registration Default"), then
interest will accrue (in

                                     -54-
<PAGE>

addition to any stated interest on the Securities) (the "Step-Up") at a rate of
0.50% per annum, determined daily, on the principal amount of the Securities,
for the period from the occurrence of the Registration Default until such time

rate of such Liquidated Damages shall increase (a "Subsequent Step-Up") by an
additional 0.50% per annum for each subsequent 90-day period (provided that the
Step-Up and all subsequent Step-Up interest rates shall not exceed 1.0% per
annum in the aggregate) and Liquidated Damages will be payable at such increased
rate until such time (the "Subsequent Step Down Date") as all Registration
Defaults have been cured. Interest accruing as a result of the Step-Up or the
Subsequent Step-Up (which shall be computed on the basis of a 365-day year) is
referred to herein as "Liquidated Damages." Accrued Liquidated Damages, if any,
shall be paid semi-annually on January 15 and July 15 in each year; and the
amount of accrued Liquidated Damages shall be determined on the basis of the
number of days actually elapsed. Any accrued and unpaid interest (including
Liquidated Damages) on this Security upon the issuance of an Exchange Security
(as defined in the Indenture) in exchange for this Security shall cease to be
payable to the Holder hereof but such accrued and unpaid interest (including
Liquidated Damages) shall be payable on the next Interest Payment Date for such
Exchange Security to the Holder thereof on the related Regular Record Date. The
interest (including Liquidated Damages) so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest, which shall be the January 1 or July 1 (whether or not a
Business Day), as the case may be, next preceding such Interest Payment Date.
Any such interest (including Liquidated Damages) not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities not less
than 10 days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Securities may be

                                     -55-

fully provided in said Indenture.

(and Liquidated Damages, if any) on this Security will be made at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,

as at the time of payment is legal tender for payment of public and private
debts; provided, however, that at the option of the Company payment of interest

purposes have the same effect as if set forth at this place.

by the Trustee referred to on the reverse hereof by manual signature, this
Security shall not be entitled to any benefit under the Indenture or be valid or

called the "Securities"), limited in aggregate principal amount to $900,000,000,

                                     -56-
<PAGE>

issued and to be under an Indenture, dated as of July 2, 2001 (herein called the
"Indenture"), between the Company and Wilmington Trust Company, as Trustee
(herein called the "Trustee", which term includes any successor trustee under
the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered.

               At any time, the Company may redeem all or a part of the
Securities upon not less than 30 nor more than 60 days' notice at a Redemption
Price equal to the applicable Treasury Make-whole, plus accrued and unpaid
interest (and Liquidated Damages, if any), thereon to the applicable Redemption
Date.

               The Securities do not have the benefit of any sinking fund
obligations.

               In the event of redemption or purchase pursuant to an Offer to
Purchase of this Security in part only, a new Security or Securities for the
unredeemed or unpurchased portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

               The Indenture provides that, subject to certain conditions, if
(i) certain Net Cash Proceeds are available to the Company as a result of Asset
Sales or (ii) a Change of Control occurs, the Company shall be required to make
an Offer to Purchase for all or part of the Securities.

               If an Event of Default shall occur and be continuing, the
principal of all the Securities may be declared due and payable in the manner
and with the effect provided in this Indenture.

               The Indenture contains provisions for defeasance at any time of
(i) the entire indebtedness of this Security or (ii) certain restrictive
covenants and Events of Default with respect to this Security, in each case upon
compliance with certain conditions set forth therein.

redemptions and Offers to Purchase.

               The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities under
the Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in aggregate principal amount of the Securities at the
time Outstanding. The Indenture also contains provisions permitting the Holders
of specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, to waive
compliance by the Company with certain provisions of the Indenture and certain
past Defaults under the Indenture and their consequences. Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Security.

Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of (and

therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in the Borough of Manhattan, The City of New

form satisfactory to the Company and the Security Registrar duly executed by,

or more new Securities, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

               The Securities are issuable only in registered form without
coupons in denominations of $1,000 and any

                                     -58-
<PAGE>

integral multiple of $1,000 above that amount. As provided in the Indenture and
subject to certain limitations therein set forth, Securities are exchangeable
for a like aggregate principal amount of Securities of a different authorized
denomination, as requested by the Holder surrendering the same.

               No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

               Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee

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

               This is one of the Securities referred to in the within-mentioned
Indenture.

                                               Wilmington Trust Company

                                               By ___________________________
                                                  Authorized Officer

                                 ARTICLE THREE

                                 The Securities

SECTION 301.        Title and Terms.
                    ---------------

               The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to $900,000,000,
except for Securities authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Securities pursuant to Section 304,
306, 307, 906 or 1108 or in connection with an Offer to Purchase pursuant to
Section 1016 or 1017.

               The Company may issue Exchange Securities from time to time
pursuant to an Exchange Offer or otherwise, in each case pursuant to a Board
Resolution, subject to Section 303, included in an Officers' Certificate
delivered to the Trustee, in authorized denominations in exchange for a like
principal amount of Original Securities. Upon any such exchange the Original
Securities shall be canceled in accordance with Section 310 and shall no longer
be deemed Outstanding for any purpose. In no event shall the aggregate principal
amount of Original Securities and Exchange Securities Outstanding exceed
$900,000,000.

               The Securities shall be known and designated as the "13.50%
Senior Secured Notes due 2008" of the Company. Their Stated Maturity shall be
July 15, 2008 and they shall bear interest at the rate of 13.50% per annum, from
July 2, 2001 or from the most recent Interest Payment Date thereafter to which
interest has been paid or duly provided

                                     -62-
<PAGE>

for, as the case may be, payable semi-annually on January 15 and July 15,
commencing January 15, 2002, until the principal thereof is paid or made
available for payment; PROVIDED, HOWEVER, with respect to Original Securities,
if there has been a Registration Default, a Step-Up will occur and the Original
Securities will from then bear Liquidated Damages until the Step-Down Date and
there shall be a Subsequent Step-Up for each subsequent 90-day period (provided
that the Step-Up and all Subsequent Step-Up interest rates shall not exceed 1.0%
per annum in aggregate) and the Original Securities will from then bear
Liquidated Damages until the Subsequent Step-Down Date. Accrued Liquidated
Damages, if any, shall be paid in cash in arrears semi-annually on January 15
and July 15 in each year, and the amount of accrued Liquidated Damages shall be
determined on the basis of the number of days actually elapsed. In connection
with the cash payment of any Liquidated Damages, the Company shall notify the
Trustee (the "Liquidated Damages Notice") on or before the later to occur of (i)
the Regular Record Date preceding such payment of any Liquidated Damages, and
(ii) the date on which any such Liquidated Damages begins to accrue, of the
amount of Liquidated Damages to be paid by the Company on the next Interest
Payment Date. In the event of the occurrence of a Step-Down Date or Subsequent
Step Down Date during the period between the date on which the Liquidated
Damages Notice is given and the next Interest Payment Date, the Company shall so
notify the Trustee and shall provide the Trustee with the revised amount of
Liquidated Damages to be paid by the Company on such Interest Payment Date.

               If this Security is issued in the form of a Global Security,
payments of the principal of (and premium, if any) and interest (and Liquidated
Damages, if any) on this Security shall be made in immediately available funds
to the Depositary. If the Securities are issued in certificated form, the
principal of and premium, if any, and interest and Liquidated Damages, if any,
on the Securities shall be payable at the office or agency of the Company in the
Borough of Manhattan, The City of New York, New York, maintained for such
purpose and at any other office or agency maintained by the Company for such
purpose; PROVIDED, HOWEVER, that at the option of the Company, payment of
interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register.

                                     -63-

               The Securities shall be subject to repurchase by the Company
pursuant to an Offer to Purchase as provided in Section 1016 and Section 1017.

               The Securities shall be redeemable as provided in Article Eleven.

               The Securities shall be subject to defeasance at the option of
the Company as provided in Article Twelve.

SECTION 302.        Denominations.
                    -------------

               The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 and any integral multiple of $1,000
above that amount.

SECTION 303.        Execution, Authentication, Delivery and Dating.
                    ----------------------------------------------

               The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Chief Executive Officer, its Chief Financial Officer,
its President or one of its Vice Presidents. The signature of any of these
officers on the Securities may be manual or facsimile.

               Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwith standing that such individuals or any of them have ceased
to hold such offices prior to the authentication and delivery of such Securities
or did not hold such offices at the date of such Securities.

               At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise.

               At any time and from time to time after the execution and
delivery of this Indenture and after the effectiveness of a Registration
Statement under the

                                     -64-
<PAGE>

Securities Act with respect thereto, the Company may deliver Exchange Securities
executed by the Company to the Trustee for authentication, together with a
Company Order for the authentication and delivery of such Exchange Securities
and a like principal amount of Original Securities for cancellation in
accordance with Section 310 of this Indenture, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities. In
authenticating such Exchange Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating,

                    (a) that such Exchange Securities have been duly and validly
               issued in accordance with the terms of this Indenture, and are
               entitled to all the rights and benefits set forth herein; and

                    (b) that the issuance of the Exchange Securities in exchange
               for the Original Securities has been effected in compliance with
               the Securities Act of 1933, as amended.

               Each Security shall be dated the date of its authentication.

               No Security shall be entitled to any benefit under this Indenture
or be valid or obligatory for any purpose unless there appears on such Security
a certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder.

SECTION 304.        Temporary Securities.
                    --------------------

               Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as

                                     -65-
<PAGE>

the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

               If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Company designated pursuant to Section
1002, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations. Until so exchanged the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

SECTION 305.        Global Securities
                    -----------------

               (a) Each Global Security authenticated under this Indenture shall
be registered in the name of the Depositary designated by the Company for such
Global Security or a nominee thereof and delivered to such Depositary or a
nominee thereof or custodian therefor, and each such Global Security shall
constitute a single Security for all purposes of this Indenture.

               (b) Notwithstanding any other provision in this Indenture, no
Global Security may be exchanged in whole or in part for Securities registered,
and no transfer of a Global Security in whole or in part may be registered, in
the name of any Person other than the Depositary for such Global Security or a
nominee thereof unless (i) such Depositary (A) has notified the Company that it
is unwilling or unable to continue as Depositary for such Global Security or (B)
has ceased to be a clearing agency registered as such under the Exchange Act,
and in either case the Company fails to appoint a successor Depositary within 90
days, (ii) the Company executes and delivers to the Trustee a Company Order
stating that it elects to cause the issuance of the Securities in certificated
form and that all Global Securities shall be exchanged in whole for Securities
that are not Global Securities (in which case such exchange shall be effected by
the Trustee) or (iii) there shall have occurred and be continuing an Event of
Default or any Event

                                     -66-
<PAGE>

which after notice or lapse of time or both would be an Event of Default with
respect to the Securities.

               (c)  If any Global Security is to be exchanged for other
Securities or canceled in whole, it shall be surrendered by or on behalf of the
Depositary or its nominee to the Trustee, as Security Registrar, for exchange or
cancellation as provided in this Article Three. If any Global Security is to be
exchanged for other Securities or canceled in part, or if another Security is to
be exchanged in whole or in part for beneficial interest in any Global Security,
then either (i) such Global Security shall be so surrendered for exchange or
cancellation as provided in this Article Three or (ii) the principal amount
thereof shall be reduced or increased by an amount equal to the portion thereof
to be so exchanged or canceled, or equal to the principal amount of such other
Security to be so exchanged for a beneficial interest therein, as the case may
be, by means of an appropriate adjustment made on the records of the Trustee, as
Security Registrar, whereupon the Trustee, in accordance with the Applicable
Procedures, shall instruct the Depositary or its authorized representative to
make a corresponding adjustment to its records. Upon any such surrender or
adjustment of a Global Security, the Trustee shall, subject to Section 306(c)
and as otherwise provided in this Article Three, authenticate and deliver any
Securities issuable in exchange for such Global Security (or any portion
thereof) to or upon the order of the Company, and registered in such names as
may be directed by, the Depositary or its authorized representative. Upon the
request of the Trustee in connection with the occurrence of any of the events
specified in the preceding paragraph, the Company shall promptly make available
to the Trustee a reasonable supply of Securities that are not in the form of
Global Securities. The Trustee shall be entitled to rely upon any order,
direction or request of the Depositary or its authorized representative which is
given or made pursuant to this Article Three if such order, direction or request
is given or made in accordance with the Applicable Procedures.

               (d)  Every Security authenticated and delivered upon registration
of transfer of, or in exchange for or in lieu of, a Global Security or any
portion thereof, whether pursuant to this Article Three or otherwise, shall be
authenticated and delivered in the form of, and shall be, a Global Security,
unless such Security is registered in the

                                     -67-
<PAGE>

name of a Person other than the Depositary for such Global Security or a nominee
thereof.

               (e)  The Depositary or its nominee, as registered owner of a
Global Security, shall be the Holder of such Global Security for all purposes
under this Indenture and the Securities, and owners of beneficial interests in a
Global Security shall hold such interests pursuant to the Applicable Procedures.
Accordingly, any such owner's beneficial interest in a Global Security will be
shown only on, and the transfer of such interest shall be effected only through,
records maintained by the Depositary or its nominee or its Agent Members.

               (f)  No holder of a beneficial interest in any Global Security
held on its behalf by a Depositary shall have any rights under this Indenture
with respect to such Global Security, and such Depositary may be treated by the
Company, the Trustee, and any agent of the Company or the Trustee as the owner
of such Global Security for all purposes whatsoever. None of the Company, the
Trustee or any agent of the Company or the Trustee will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Global Security or maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by a
Depositary or impair, as between a Depositary and such holder of beneficial
interests, the operation of customary practices governing the exercise of the
rights of the Depositary (or its nominee) as holder of any Security.

SECTION 306.        Registration, Registration of Transfer and Exchange.
                    ---------------------------------------------------

               (a)  The Company shall cause to be kept at the Corporate Trust
Office a register (the register maintained in such office or in any other office
or agency designated pursuant to Section 1002 being herein sometimes referred to
as the "Security Register") in which, subject to such reasonable regulations as
it may prescribe, the Company shall provide for the registration of Securities
and of

                                     -68-
<PAGE>

transfers of Securities and exchanges of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers and exchanges of Securities as herein provided.

               Such Security Register shall distinguish between Original
Securities and Exchange Securities.

               Subject to the other provisions of this Indenture regarding
restrictions on transfer, upon surrender for registration of transfer of any
Security at an office or agency of the Company designated pursuant to Section
1002 for such purpose in accordance with the terms hereof, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of any
authorized denominations and of a like tenor and aggregate principal amount and
bearing such restrictive legends as may be required by this Indenture.

               At the option of the Holder and subject to other provisions of
this Section 306 and Section 305, Securities may be exchanged for other
Securities of any authorized denominations and of a like tenor and aggregate
principal amount and bearing the applicable legends set forth in Section 202,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

               All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing
the same debt, and (subject to the provisions in the Original Securities
regarding the payment of Liquidated Damages) entitled to the same benefits under
this Indenture, as the Securities surrendered upon such registration of transfer
or exchange.

               Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly

                                     -69-
<PAGE>

executed, by the Holder thereof or his attorney duly authorized in writing.

               No service charge shall be made for any registration of transfer
or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 305, 906 or 1108 or in accordance with any
Offer to Purchase pursuant to Section 1016 or Section 1017, not involving any
transfer.

               The Company shall not be required (i) to issue, register the
transfer of or exchange any Security during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities selected for redemption under Section 1104 and ending at the close of
business on the day of such mailing, or (ii) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.

               (b)  Certain Transfers and Exchanges. Notwithstanding any other
provision of this Indenture or the Securities, transfers and exchanges of
Securities and beneficial interests in a Global Security of the kinds specified
in this Section 306(b) shall be made only in accordance with this Section
306(b).

                    (i) Restricted Global Security to Regulation S Global
               Security. If the owner of a beneficial interest in the Restricted
               Global Security wishes at any time to transfer such interest to a
               Person who wishes to acquire the same in the form of a beneficial
               interest in the Regulation S Temporary Global Security (if before
               the expiration of the Restricted Period) or in the Regulation S
               Permanent Global Security (if thereafter), such transfer may be
               effected only in accordance with the provisions of this Clause
               (b)(i) subject to the Applicable Procedures. Upon receipt by the
               Trustee, as Security Registrar, of (A) an order given by the
               Depositary or its authorized representative directing that a
               beneficial interest in the Regulation S Temporary Global Security
               or Regulation S Permanent Global Security

                                     -70-
<PAGE>

               (as applicable) in a specified principal amount be credited to a
               specified Agent Member's account and that a beneficial interest
               in the Restricted Global Security in an equal principal amount be
               debited from another specified Agent Member's account and (B) a
               Regulation S Certificate, substantially in the form attached
               hereto as Annex A duly executed by the owner of such beneficial
               interest in the Restricted Global Security or his attorney duly
               authorized in writing, then the Trustee, as Security Registrar
               but subject to Clause (b)(iv) below, shall reduce the principal
               amount of the Restricted Global Security and increase the
               principal amount of the Regulation S Temporary Global Security or
               Regulation S Permanent Global Security (as applicable) by such
               specified principal amount as provided in Section 306(b).

                    (ii) Regulation S Temporary Global Security to Restricted
               Global Security. If the owner of a beneficial interest in the
               Regulation S Temporary Global Security wishes at any time to
               transfer such interest to a Person who wishes to acquire the same
               in the form of a beneficial interest in the Restricted Global
               Security, such transfer may be effected only in accordance with
               this Clause (b)(ii) and subject to the Applicable Procedures.
               Upon receipt by the Trustee, as Security Registrar, of (A) an
               order given by the Depositary or its authorized representative
               directing that a beneficial interest in the Restricted Global
               Security in a specified principal amount be credited to a
               specified Agent Member's account and that a beneficial interest
               in the Regulation S Temporary Global Security in an equal
               principal amount be debited from another specified Agent Member's
               account and (B) a Restricted Securities Certificate,
               substantially in the form attached hereto as Annex B duly
               executed by the owner of such beneficial interest in the
               Regulation S Temporary Global Security or his attorney duly
               authorized in writing, then the Trustee, as Security Registrar,
               shall reduce the principal amount of the Regulation S Temporary
               Global Security and increase the principal amount of the

                                     -71-
<PAGE>

               Restricted Global Security by such specified principal amount as
               provided in Section 306(b).

                    (iii)  Exchanges between Global Security and Non-Global
               Security. A beneficial interest in a Global Security may be
               exchanged for a Security that is not a Global Security as
               provided in Section 305, provided that, if such interest is a
               beneficial interest in the Restricted Global Security, or if such
               interest is a beneficial interest in the Regulation S Temporary
               Global Security, then such interest shall be exchanged for a
               Restricted Security (subject in each case to Section 306(c)).

                    (iv)  Regulation S Temporary Global Security to be Held
               Through Euroclear or Clearstream during Restricted Period. The
               Company shall use its best efforts to cause the Depositary to
               ensure that beneficial interests in the Regulation S Temporary
               Global Security may be held only in or through accounts
               maintained at the Depositary by Euroclear or Clearstream (or by
               Agent Members acting for the account thereof), and no person
               shall be entitled to effect any transfer or exchange that would
               result in any such interest being held otherwise than in or
               through such an account; provided that this Clause (b)(iv) shall
               not prohibit any transfer or exchange of such an interest in
               accordance with Clause (b)(ii) above.

               (c)  Securities Act Legends. Rule 144A Securities and their
respective Successor Securities shall bear a Restricted Securities Legend, and

Regulation S Legend, subject to the following:

                    (i)  subject to the following Clauses of this Section
               306(c), a Security or any portion thereof which is exchanged,
               upon transfer or otherwise, for a Global Security or any portion
               thereof shall bear the Securities Act Legend borne by such Global
               Security while represented thereby;

                    (ii) subject to the following Clauses of this Section

               transfer or otherwise, shall bear the Securities Act Legend borne
               by such other Security, provided that, if such new Security is
               required pursuant to Section 306(b)(iii) to be issued in the form
               of a Restricted Security, it shall bear a Restricted Securities
               Legend and, if such new Security is so required to be issued in
               the form of a Regulation S Global Security, it shall bear a
               Regulation S Legend;

                    (iii)  Exchange Securities shall not bear a Securities Act
               Legend;

                    (iv)   at any time after the Securities may be freely
               transferred without registration under the Securities Act or
               without being subject to transfer restrictions pursuant to the
               Securities Act, a new Security which does not bear a Securities
               Act Legend may be issued in exchange for or in lieu of a Security
               (other than a Global Security) or any portion thereof which bears
               such a legend if the Trustee has received an Unrestricted
               Securities Certificate, substantially in the form attached hereto
               as Annex C duly executed by the Holder of such legended Security
               or his attorney duly authorized in writing, and after such date
               and receipt of such certificate, the Trustee shall authenticate
               and deliver such a new Security in exchange for or in lieu of
               such other Security as provided in this Article Three;

                    (v)    a new Security which does not bear a Securities Act
               Legend may be issued in exchange for or in lieu of a Security
               (other than a Global Security) or any portion thereof which bears
               such a legend if, in the Company's judgment, placing such a
               legend upon such new Security is not necessary to ensure
               compliance with the registration requirements of the Securities
               Act, and the Trustee, at the direction of the Company, shall
               authenticate and deliver such a new Security as provided in this
               Article Three; and

                    (vi)  notwithstanding the foregoing provisions of this
               Section 306(c), a Successor Security of a Security that does not
               bear a particular form of Securities Act Legend shall not bear
               such form of legend unless the Company has reasonable cause to
               believe that such Successor Security is a "restricted security"
               within the meaning of Rule 144, in which case the Trustee, at the
               direction of the Company, shall authenticate and deliver a new
               Security bearing a Restricted Securities Legend in exchange for
               such Successor Security as provided in this Article Three.

SECTION 307.        Mutilated, Destroyed, Lost and Stolen Securities.
                    ------------------------------------------------

               If any mutilated Security is surrendered to the Trustee, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

               If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

               In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

               Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                                     -74-
<PAGE>

               Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

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

SECTION 308.        Payment of Interest; Interest Rights Preserved.
                    ----------------------------------------------

               Interest (including Liquidated Damages, if any) on any Security
which is payable, and is punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name that Security (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest.

               Any interest (including Liquidated Damages, if any) on any
Security which is payable, but is not punctually paid or duly provided for, on
any Interest Payment Date (herein called "Defaulted Interest") shall forthwith
cease to be payable to the Holder on the relevant Regular Record Date by virtue
of having been such Holder, and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in Clause (1) or (2) below:

               (1) The Company may elect to make payment of any Defaulted
          Interest to the Persons in whose names the Securities (or their
          respective Predecessor Securities) are registered at the close of
          business on a Special Record Date for the payment of such Defaulted
          Interest, which shall be fixed in the following manner. The Company
          shall notify the Trustee in writing of the amount of Defaulted
          Interest proposed to be paid on each Security and the date of the
          proposed payment, and at the same time the Company

                                     -75-
<PAGE>

          shall deposit with the Trustee an amount of money equal to the
          aggregate amount proposed to be paid in respect of such Defaulted
          Interest or shall make arrangements satisfactory to the Trustee for
          such deposit prior to the date of the proposed payment, such money
          when deposited to be held in trust for the benefit of the Persons
          entitled to such Defaulted Interest as in this Clause provided.
          Thereupon the Trustee shall fix a Special Record Date for the payment
          of such Defaulted Interest which shall be not more than 15 days and
          not less than 10 days prior to the date of the proposed payment and
          not less than 10 days after the receipt by the Trustee of the notice
          of the proposed payment. The Trustee shall promptly notify the Company
          of such Special Record Date and, in the name and at the expense of the
          Company, shall cause notice of the proposed payment of such Defaulted
          Interest and the Special Record Date therefor to be mailed, first-
          class postage prepaid, to each Holder at his address as it appears in
          the Security Register, not less than 10 days prior to such Special
          Record Date. Notice of the proposed payment of such Defaulted Interest
          and the Special Record Date therefor having been so mailed, such
          Defaulted Interest shall be paid to the Persons in whose names the
          Securities (or their respective Predecessor Securities) are registered
          at the close of business on such Special Record Date and shall no
          longer be payable pursuant to the following Clause (2).

               (2) The Company may make payment of any Defaulted Interest in any
          other lawful manner not inconsistent with the requirements of any
          securities exchange on which the Securities may be listed, and upon
          such notice as may be required by such exchange, if, after notice
          given by the Company to the Trustee of the proposed payment pursuant
          to this Clause, such manner of payment shall be deemed practicable by
          the Trustee.

               Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 309.        Persons Deemed Owners.
                    ---------------------

               Prior to due presentment of a Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered as the owner of
such Security for the purpose of receiving payment of principal of (and premium,
if any) and (subject to Section 308) interest (and Liquidated Damages, if any)
on such Security and for all other purposes whatsoever, whether or not such
Security be overdue, and neither the Company, the Trustee nor any agent of the
Company or the Trustee shall be affected by notice to the contrary.

SECTION 310.        Cancellation.
                    ------------

               All Securities surrendered for payment, redemption, registration
of transfer or exchange or pursuant to any Offer to Purchase pursuant to Section
1016 or Section 1017 shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee and shall be promptly canceled by it. The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly canceled by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture. All canceled Securities held by
the Trustee shall be disposed of in accordance with its standard procedures or
as directed by a Company Order; provided, however, that the Trustee shall not be
                                --------  -------
required to destroy such Securities.

SECTION 311.        Computation of Interest.
                    -----------------------

               Interest on the Securities shall be computed on the basis of a

that Liquidated Damages shall be computed on the basis of a 365-day year.

SECTION 312.   CUSIP Numbers.
               -------------

          The Company in issuing Securities may use "CUSIP and "ISIN" numbers
(if then generally in use) in addition to serial numbers; if so, the Trustee
shall use such "CUSIP" and "ISIN" numbers in addition to serial numbers in
notices of redemption and repurchase as a convenience to Holders; PROVIDED that
any such notice may state that no representation is made as to the correctness
of such CUSIP and ISIN numbers either as printed on the Securities or as
contained in any notice of a redemption or repurchase and that reliance may be
placed only on the serial or other identification numbers printed on the
Securities, and any such redemption or repurchase shall not be affected by any
defect in or omission of such CUSIP and ISIN numbers.

               (b)  all Securities that have not been delivered to the Trustee
          for cancellation have become due and payable by reason of the making

          be deposited with the Trustee as trust funds in trust solely for the

    party or by which it is bound;

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

          (4)  the Company has delivered irrevocable instructions to the Trustee
    under this Indenture to apply the deposited money toward the payment of the

          of entities, as applicable, described in Clauses (a) through (c) above
          to the entry of a decree or order for relief in an involuntary case or
          proceeding under any applicable Federal or State bankruptcy,
          insolvency, reorganization or other similar law or to the commencement
          of any bankruptcy or insolvency case or proceeding against any of them
          or (iii) the filing of a petition or answer or consent seeking
          reorganization or relief under any applicable Federal or State law, or
          the consent to the filing of such petition or to the appointment of or

          any of the entities or group of entities, as applicable, described in

          described in Clause (c) above, such event or events shall not
          constitute an Event of Default hereunder unless such event or events
          would reasonably be expected to have a Material Adverse Effect.

                                     -84-
<PAGE>

     In the case of any Event of Default occurring by reason of any willful
action or inaction taken or not taken by or on behalf of the Company with the
intention of avoiding payment of the premium that it would have to have paid if
it then had elected to redeem the Securities pursuant to Section 1101, an
equivalent premium will also become and be immediately due and payable to the
extent permitted by law upon the acceleration of the Securities.

SECTION 502.   Acceleration of Maturity; Rescission and Annulment.
               --------------------------------------------------

          If an Event of Default (other than an Event of Default specified in
Section 501(8) or Section 501(9), with respect to the Company or Edison Mission
Energy) occurs and is continuing, then and in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
may declare the principal of all the Securities to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal and any accrued
interest (and Liquidated Damages, if any), shall become immediately due and
payable. If an Event of Default specified in Section 501(8) or 501(9) with
respect to the Company or Edison Mission Energy occurs and is continuing, the
principal and any accrued interest (and Liquidated Damages, if any) on the
Securities then Outstanding shall ipso facto become immediately due and payable
                                  ---- -----
without any declaration or other Act on the part of the Trustee or any Holder.

          At any time after such a declaration of accelera tion has been made
and before a judgment or decree for pay ment of the money due has been obtained
by the Trustee as hereinafter in this Article provided, the Holders of a
majority in principal amount of the Outstanding Securities, by written notice to
the Company and the Trustee, may rescind and annul such declaration and its
consequences if:

          (1)  the Company has paid or deposited with the Trustee a sum
          sufficient to pay:

               (A) all overdue interest and Liquidated Damages, if any, on
          all Securities;

                                     -85-
<PAGE>

               (B)  the principal of (and premium, if any, on) any Securities
          which have become due otherwise than by such declaration of
          acceleration (including any Securities required to have been purchased
          on the Purchase Date pursuant to an Offer to Purchase made by the
          Company) and, to the extent that payment of such interest is lawful,
          interest thereon at the rate provided by the Securities; and

               (C)  all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel;

     and

          (2)  all Events of Default, other than the non-payment of the
     principal of Securities which have become due solely by such declaration of
     acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent Default or impair any right
consequent thereon.

SECTION 503.   Collection of Indebtedness and Suits for Enforcement by Trustee.
               ---------------------------------------------------------------

          The Company covenants that if:

          (1)  Default is made in the payment of any interest or Liquidated
     Damages, if any, on any Security when such interest becomes due and payable
     and such Default continues for a period of 30 days, or

          (2)  Default is made in the payment of the principal of (or premium,
     if any, on) any Security at the Maturity thereof or, with respect to any
     Security required to have been purchased pursuant to an Offer to Purchase

                                     -86-
<PAGE>

     made by the Company, at the Purchase Date thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest (and Liquidated
Damages, if any), and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal (and premium, if any) and
on any overdue interest, at the rate provided by the Securities, and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effective to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 504.   Trustee May File Proofs of Claim.
               --------------------------------

          In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any

                                     -87-
<PAGE>

moneys or other property payable or deliverable on any such claims and to
distribute the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 607.

          No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

SECTION 505.   Trustee May Enforce Claims Without Possession of Securities.
               -----------------------------------------------------------

          All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

SECTION 506.   Application of Money Collected.
               ------------------------------

          Any money 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 money on account of principal (or premium,
if any) or interest (or Liquidated Damages, if any), upon presentation of the
Securities and the notation thereon of the payment if only partially paid and
upon surrender thereof if fully paid:

                                     -88-
<PAGE>

          FIRST:    To the payment of all amounts due the Trustee under Section
     607;

          SECOND:   To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) and interest (and Liquidated Damages, if
     any), on the Securities in respect of which or for the benefit of which
     such money has been collected, ratably, without preference or priority of
     any kind, according to the amounts due and payable on such Securities for
     principal (and premium, if any) and interest (or Liquidated Damages, if
     any), respectively; and

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

SECTION 507.   Limitation on Suits.
               -------------------

          No Holder of any Security shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless:

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

          (2)  the Holders of not less than 25% in principal amount of the
     Outstanding Securities shall have made written request to the Trustee to
     institute proceedings in respect of such Event of Default in its own name
     as Trustee hereunder;

          (3)  such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

          (4)  the Trustee for 60 days after its receipt of such notice, request
     and offer of

                                     -89-
<PAGE>

     indemnity has failed to institute any such proceeding; and

          (5)  no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     in principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

SECTION 508.   Unconditional Right of Holders to Receive Principal, Premium and
               ----------------------------------------------------------------
               Interest.
               --------

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 308) interest (and Liquidated Damages, if any), on such Security on the
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date or in the case of an Offer to Purchase made
by the Company and required to be accepted as to such Security, on the Purchase
Date) and to institute suit for the enforcement of any such payment, and such
rights shall not be impaired without the consent of such Holder.

SECTION 509.   Restoration of Rights and Remedies.
               ----------------------------------

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Inden ture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the

                                     -90-
<PAGE>

Trustee and the Holders shall continue as though no such proceeding had been
instituted.

SECTION 510.   Rights and Remedies Cumulative.
               ------------------------------

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 307, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders 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.

SECTION 511.   Delay or Omission Not Waiver.
               ----------------------------

          No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 512.   Control by Holders.
               ------------------

          The Holders of a majority in principal amount of the Outstanding
Securities 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, provided that:
                                             --------

          (1)  such direction shall not be in conflict with any rule of law or
     with this Indenture;

          (2)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction; and

                                     -91-
<PAGE>

          (3)  the Trustee shall have the right to decline to follow any such
     direction if the Trustee in good faith shall, by a Responsible Officer or
     Officers of the Trustee, determine that the proceeding so directed would
     involve the Trustee in personal liability against which indemnification
     would not be satisfactory.

SECTION 513.   Waiver of Past Defaults.
               -----------------------

          The Holders of not less than a majority in principal amount of the
Outstanding Securities may on behalf of the Holders of all the Securities waive
any past Default or Event of Default hereunder and its consequences, except a
continuing Default or Event of Default:

          (1)  in the payment of the principal of (or premium, if any) or
     interest (or Liquidated Damages, if any), on any Security (including any
     Security which is required to have been purchased pursuant to an Offer to
     Purchase which has been made by the Company); or

          (2)  in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security affected.

          Upon any such waiver, such Default or Event of Default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been
cured, for every purpose of this Indenture; but no such waiver shall extend to
any subsequent or other Default or impair any right consequent thereon.

SECTION 514.   Undertaking for Costs.
               ---------------------

          In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the

                                     -92-
<PAGE>

manner and to the extent provided in the Trust Indenture Act; provided, that
                                                              --------
neither this Section nor the Trust Indenture Act shall be deemed to authorize
any court to require such an undertaking or to make such an assessment in any
suit instituted by the Company.

SECTION 515.   Waiver of Stay or Extension Laws.
               --------------------------------

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

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

          The duties, responsibilities and protections of the Trustee shall be
as provided by the Trust Indenture Act. Notwithstanding the foregoing, no
provision of this Indenture or any Security Document shall require the Trustee
to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it. Whether or not therein expressly so provided,
every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the
provisions of this Section.

in the case of any Default of the character specified in Section 501(5), no such
notice to Holders shall be given until at least 30 days after the occurrence
thereof. The Trustee may withhold from Holders of the Securities notice of any
continuing Default or Event of Default if the Trustee determines that
withholding notice is in the best interest of the Holders of the Securities,
except a Default or Event of Default of specified in Section 501(1) and Section
501(2).

SECTION 603.   Certain Rights of Trustee.
               -------------------------

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

          The recitals contained herein shall not be taken as the

     Section 607) and of defending itself against any claim (whether asserted by
     any Holder or the Company) or liability in connection with the exercise or

     The Trustee shall have a lien prior to the Securities upon all property and

has a combined capital and surplus of at least $50,000,000 and its Corporate
Trust Office in the Borough of Manhattan, The City of New York, New York or

<PAGE>

          (d)  If at any time:

          (1)  the Trustee shall fail to comply with Section 608 after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder of a Security for at least six months, or

          (2)  the Trustee shall cease to be eligible under Section 609 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder, or

          (3)  the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver 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, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide

          (e)  If the Trustee shall resign, be removed or become incapable of

within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Company.
If no successor Trustee shall have been so appointed by the Company or the
Holders and accepted appointment in the manner hereinafter provided, any Holder
who has been a bona fide Holder of a Security for at least

                                     -99-
<PAGE>

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

          Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee; but, on request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder. Upon request of any such successor Trustee, the
Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and

conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be

                                     -100-
<PAGE>

otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties hereto.
In case any Securities shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities.

SECTION 613.   Preferential Collection of Claims Against Company.
               -------------------------------------------------

          If and when the Trustee shall be or become a creditor of the Company

provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

SECTION 614.   Appointment of Authenticating Agent.
               -----------------------------------

          The Trustee may appoint an Authenticating Agent or Agents which shall
be authorized to act on behalf of the Trustee to authenticate Securities issued
upon original issue and upon exchange, registration of transfer or partial
redemption or pursuant to Section 307, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of

                                     -101-
<PAGE>

this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

          Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders as their
names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

          The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

Indenture.

Manhattan, The City of New York or Wilmington, Delaware, for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

                   The Company hereby designates the Corporate Trust Office as

                        -----

                   If the Company shall at any time act as its own Paying Agent,
it will, on or before each due date of the principal of (and premium, if any) or
interest (and Liquidated Damages, if any), on any of the Securities, segregate
and hold in trust for the benefit of the Persons entitled thereto a sum
sufficient to pay the principal (and premium, if any) or interest (and
Liquidated Damages, if any), so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided and will promptly
notify the Trustee of its action or failure so to act.

interest (and Liquidated Damages, if any), on any Securities, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest (and Liquidated Damages, if any), so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such principal (and premium,
if any) or interest (and Liquidated Damages, if any) and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

                   The Company will cause each Paying Agent other than the
Trustee to execute and deliver to the Trustee an

                                     -111-

instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will:

                   (1) hold all sums held by it for the payment of the principal
         of (and premium, if any) or interest (and Liquidated Damages, if any),
         on Securities in trust for the benefit of the Persons entitled thereto
         until such sums shall be paid to such Persons or otherwise disposed of
         as herein provided;

                   (2) give the Trustee notice of any Default by the Company (or
         any other obligor upon the Securities) in the making of any payment of
         principal (and premium, if any) or interest (and Liquidated Damages, if
         any); and

                   (3) at any time during the continuance of any such Default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

                   The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

                   Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (and
premium, if any) or interest (and Liquidated Damages, if any), on any Security
and remaining unclaimed for two years after such principal (and premium, if any)
or interest (and Liquidated Damages, if any), has become due and payable shall
be paid to the Company on Company Request, or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look

                                     -112-

only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
                                                   --------  -------
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in The City of New York, notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such publication, any unclaimed balance of

do or cause to be done all things necessary to preserve and keep in full force
and effect its existence, rights (charter and statutory) and franchises;
provided, however, that the Company shall not be required to preserve any such

of the Company and that the loss thereof is not disadvantageous in any material
respect to the Holders.

in the conduct of its business or the business of any Subsidiary of the Company
to be maintained and kept in good condition, repair and working order (ordinary
wear and tear excepted) and supplied with all necessary equipment and will cause
to be made all necessary repairs, renewals, replacements, betterments and
improve ments thereof, all as in the judgment of the Company or such Subsidiary
may be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
                                                    --------  -------
nothing in this Section shall prevent the Company from discontinuing the
operation or maintenance of any of such properties if such discontinuance is, as
determined by the Board of Directors in good faith, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.

discharged, before the same shall become delinquent, (1) all taxes, assessments
and governmental charges levied or imposed upon the Company or any of its
Restricted Subsidiaries or upon the income, profits or property of the Company

in accordance with good business practice.

         SECTION 1008.  Limitation on Incurrence of Indebtedness.
                        ----------------------------------------

               twelve-month period);

          (5)  payments made pursuant to the Tax Sharing Agreements; provided
               such payments may be made whether or not a Default then exists;

          (6)  the payment by the Company to The Mission Group of the net cash
               proceeds from the sale of the Securities or the incurrence of
               indebtedness under the Term Loan; provided that in connection
               with any such payment all such net cash proceeds so paid are

Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any assets or securities that are required to be valued

<PAGE>

          (1)  such Affiliate Transaction is on terms that are no less favorable
               to the Company or the relevant Restricted Subsidiary than those

                    the fairness to the Company or its applicable Restricted
                    Subsidiary from a financial point of view issued by an
                    accounting, appraisal or investment banking firm of national
                    standing.

SECTION 1015.  Independent Director.
               --------------------

          The Company shall maintain at least one Independent Director on its

SECTION 1016.  Change of Control.
               -----------------

          Upon a Change of Control, each Holder shall have the right to require
the Company to repurchase all or any part (equal to $1,000 or an integral
multiple of $1,000) of that Holder's Securities pursuant to an Offer to Purchase
on the terms set forth in this Section 1016 and this Indenture. In the Offer to
Purchase, the Company shall offer a Purchase Price in cash equal to 101% of the
aggregate principal amount of the Securities repurchased plus accrued and unpaid
interest and Liquidated Damages, if any, on the Securities repurchased, to the
date of purchase. Within 30 days following any Change of Control, the Company
shall mail a notice to the Trustee and each Holder describing the transaction or
transactions that constitute the Change of Control and offering to repurchase
Securities on the Purchase Date specified in the notice, which date shall be no
earlier than 30 days and no later than 60 days from the date such notice is
mailed, pursuant to the procedures required by this Indenture and described in
such notice. The Company shall comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the Securities as a result of a Change of Control. To the extent
that the provisions of any securities laws or regulations conflict with this
Section 1016, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this
Section 1016 by virtue of such conflict.

          On the Purchase Date, the Company shall, to the extent lawful:
<PAGE>

          (1)  accept for payment all Securities or portions of Securities
               properly tendered pursuant to the Offer to Purchase;

          (2)  deposit with the Paying Agent an amount equal to the Purchase
               Price in respect of all Securities or portions of Securities
               properly tendered; and

          (3)  deliver or cause to be delivered to the Trustee the Securities so
               accepted together with an Officers' Certificate stating the
               aggregate principal amount of Securities or portions of
               Securities being purchased by the Company.

               The Paying Agent will promptly mail to each Holder of Securities
properly tendered the Purchase Price for such Securities, and the Company shall
execute and issue and the Trustee shall promptly authenticate and mail (or cause
to be transferred by book entry) to each Holder a new Security equal in
principal amount to any unpurchased portion of the Securities surrendered, if
any; provided, however, that each such new Security will be in a principal
amount of $1,000 or an integral multiple of $1,000.

               This Section 1016 will be applicable regardless of whether any
other provisions of this Indenture are applicable.

               The Company will not be required to make an Offer to Purchase
upon a Change of Control if a third party makes the Offer to Purchase in the
manner, at the times and otherwise in compliance with the requirements set forth
in this Indenture applicable to an Offer to Purchase made by the Company and
purchases all the Securities or portions of the Securities properly tendered and
not withdrawn under such Offer to Purchase.

SECTION 1017.       Asset Sales.
                    -----------

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

               (1)  the Company, or any such Restricted Subsidiary, as the case
                    may be, receives consideration at the time of such Asset
                    Sale

                                     -132-
<PAGE>

                    at least equal to the fair market value of the assets
                    or Equity Interests issued or sold or otherwise disposed of;

               (2)  such fair market value is determined by the Company's Board
                    of Directors and evidenced by a resolution of its Board of
                    Directors set forth in an Officers' Certificate delivered to
                    the Trustee; and

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

                    (A)  any of the Company's or its Restricted Subsidiaries'
                         Indebtedness or other liabilities, as shown on the
                         Company's or such Restricted Subsidiary's most recent
                         balance sheet, other than contingent liabilities and
                         Indebtedness that is by its terms subordinated to the
                         Securities, that are assumed by the transferee of any
                         such assets pursuant to an agreement that releases the
                         Company or such Restricted Subsidiary from further
                         liability; and

                    (B)  any securities, notes or other obligations received by
                         the Company or any such Restricted Subsidiary from such
                         transferee that are converted within 90 days of the
                         applicable Asset Sale by the Company or such Restricted
                         Subsidiary into cash, to the extent of the cash
                         received in that conversion;

provided that Clauses (1) and (2) shall not apply to Asset Sales made pursuant
to contractual obligations existing at the date of this Indenture.

               Within 12 months after the receipt of any Net Cash Proceeds from
an Asset Sale, the Company, the applicable Restricted Subsidiary or, subject to
the immediately

                                     -133-
<PAGE>

following paragraph, any other Restricted Subsidiary may apply an amount equal
to such Net Cash Proceeds or, in the case of Clause (3) below, enter into a
binding commitment to apply such amount if such amount is applied within 24
months after receipt of such Net Cash Proceeds, as follows:

          (1)  to permanently repay any Indebtedness that ranks equal in right
               of payment to the Securities or repay any Indebtedness of any
               Restricted Subsidiary (other than intercompany Indebtedness) and,
               if the Indebtedness repaid is revolving credit Indebtedness, to
               correspondingly reduce commitments with respect thereto;

          (2)  to make capital expenditures;

          (3)  to acquire Equity Interests in one of its Restricted Subsidiaries
               not then owned by the Company or one of its other Restricted
               Subsidiaries, to acquire Equity Interests in any Person such that
               such person becomes a Restricted Subsidiary of the Company as a
               result of such acquisition or to acquire additional Equity
               Interests in any Investment in any Person with respect to which
               the Company or any Restricted Subsidiary then owns any Equity
               Interests regardless of whether such Person becomes a Restricted
               Subsidiary as a result of such acquisition; or

          (4)  to acquire a Facility or a Permitted Business, or assets used in
               a Permitted Business, provided that such acquisition is made in
               accordance with this Indenture, including, without limitation,
               Section 1009.

               In determining compliance with the immediately preceding
paragraph, if the Company's percentage of the Equity Interests in the Restricted
Subsidiary that so applies the Net Cash Proceeds is less than its percentage of
the Equity Interests in the Restricted Subsidiary that engaged in the Asset
Sale, then the amount of Net Cash Proceeds necessary to comply with this Section
1017 will be increased so that the amount of Net Cash Proceeds attributable to
the Company's ownership interest in the entity applying the Net Cash Proceeds
(taking into account

                                     -134-
<PAGE>

all contributions by the other holders of any Equity Interests in such entity
and any change in percentage ownership interest resulting from such
contribution) equals the amount of Net Cash Proceeds attributable to the
Company's ownership interest in the entity making the Asset Sale.

          Any proceeds from an Asset Sale that are not applied or invested as
provided above in the preceding paragraph will constitute "Excess Proceeds."
When the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company
will make an Offer to Purchase to all Holders (and all holders of other
Indebtedness of the Company that is pari passu with the Securities and that
contain provisions similar to those set forth in Section 1017 with respect to
offers to purchase or redeem with the proceeds of sales of assets) to purchase
the maximum principal amount of Securities and any such other pari passu
Indebtedness that may be purchased out of the Excess Proceeds.

          The offer price in any Offer to Purchase will be equal to 100% of
principal amount plus accrued and unpaid interest and Liquidated Damages, if
any, thereon to the date of purchase (or, in respect of other pari passu
Indebtedness such lesser price, if any, as may be provided for by the terms of
such pari passu Indebtedness), and will be payable in cash. If any Excess
Proceeds remain after consummation of an Offer to Purchase, the Company may use
such Excess Proceeds for any purpose not otherwise prohibited by this Indenture.
If the aggregate principal amount of Securities and pari passu Indebtedness,
together with accrued and unpaid interest and Liquidated Damages, if any,
thereon tendered into such Offer to Purchase exceeds the amount of Excess
Proceeds, the Company shall deliver an Officers' Certificate to the Trustee
certifying the portion of such Excess Proceeds allocable to the Securities,
which shall be determined on a pro rata basis based on the principal amount of
the Securities and such other pari passu Indebtedness that was tendered, and the
Trustee shall select the Securities to be purchased on a pro rata basis in
accordance with the clause (11) of the definition of "Offer to Purchase". Upon
completion of each Offer to Purchase, the amount of Excess Proceeds will be
reset at zero.

          The Company shall comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and

                                     -135-
<PAGE>

regulations are applicable in connection with each repurchase of Securities
pursuant to an Offer to Purchase. To the extent that the provisions of any
securities laws or regulations conflict with this Section 1017, the Company
shall comply with the applicable securities laws and regulations and shall not
be deemed to have breached its obligations under this Section 1017 by virtue of
such conflict.

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

SECTION 1018.  Provision of Financial Information.
               ----------------------------------

          Whether or not required by the Commission, the Company shall furnish
to the Holders within the time periods specified in the Commission's rules and
regulations:(1) all quarterly and annual financial information that would be
required to be contained in a filing with the Commission on Forms 10-Q and 10-K
if the Company were required to file such Forms, including a "Management's

with respect to the annual information only, a report on the annual financial
statements by the Company's independent certified public accountants; and (2)
all current reports that would be required to be filed with the Commission on
Form 8-K if the Company were required to file such reports.

          In addition, following the consummation of the Exchange Offer (as
defined in the Registration Rights Agreement) whether or not required by the
Commission, the Company shall file a copy of all of the information and reports
referred to in Clauses (1) and (2) above with the Commission for public
availability within the time periods specified in the Commission's rules and
regulations (unless the Commission will not accept such a filing) and make such
information available to securities analysts and prospective investors upon
request. In addition, for so long as any Securities remain outstanding, the
Company shall furnish to the Holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.

SECTION 1019.  Separateness.
               ------------

          Notwithstanding any other provision of this Indenture, (1) it is
understood and agreed that none of Edison Mission Energy or any of its
Subsidiaries is liable for any amount that the Company owes in respect of the
Securities or is obligated to make any payments due on the Securities; (2) the
Company shall not take and shall not cause Edison Mission Energy or any of
Edison Mission Energy's Subsidiaries to take at any time any act in
contravention of Edison Mission Energy's articles of incorporation or any
applicable law; and (3) the Company shall observe all of the separateness
provisions contained in Edison Mission Energy's articles of incorporation as in
effect on the date of this Indenture, to the extent that they apply to a
shareholder of Edison Mission Energy.

SECTION 1020.  Provisions with Respect to Contact Energy.
               -----------------------------------------

          Any action or omission to take action by Contact Energy or any of its
subsidiaries which would otherwise be in contravention of the provisions of this
Indenture will not be deemed to be in contravention of this Indenture if the
steps required of the directors of Contact Energy appointed by Edison Mission
Energy to prevent such action or omission would have been in breach of
applicable New Zealand laws or regulations.

          (c)  The Company shall deliver to the Trustee within 120 days after
the end of each fiscal year a written statement by the Company's independent
public accountants stating (A) that their audit examination has included a
review of the terms of this Indenture and the Securities as they relate to
accounting matters, and (B) whether, in connection with their audit examination,
any event which, with notice or the lapse of time or both, would constitute an
Event of Default has come to their attention and, if such a Default has come to
their attention, specifying the nature and period of the existence thereof.

SECTION 1023.  Waiver of Certain Covenants.
               ---------------------------

          The Company may omit in any particular instance to comply with any
covenant or condition set forth in Section 801(4) and Sections 1004 to 1018, if
before the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Securities shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such

SECTION 1101.  Right of Redemption.
               -------------------

          At any time, the Company may redeem all or a part of the Securities
upon not less than 30 nor more than 60 days' notice at a Redemption Price equal
to the applicable Treasury Make-whole, plus accrued and unpaid interest and

                                     -138-
<PAGE>

Liquidated Damages, if any, thereon to the applicable Redemption Date.

SECTION 1102.  Applicability of Article.
               ------------------------

by any provision of this Indenture, shall be made in accordance with such
provision and this Article.

SECTION 1103.  Election to Redeem; Notice to Trustee.
               -------------------------------------

          The election of the Company to redeem any Securities pursuant to
Section 1101 shall be evidenced by a Board Resolution. In case of any redemption
at the election of the Company, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities to be redeemed. In addition, the Company
shall give the Trustee notice of the Redemption Price promptly after the
calculation thereof and the Trustee shall have no responsibility for such
calculation.

SECTION 1104.  Selection by Trustee of Securities to Be Redeemed.
               -------------------------------------------------

          If less than all the Securities are to be redeemed at any time, the
particular Securities or portions thereof to be redeemed shall be selected by
the Trustee, not more than 60 days prior to the Redemption Date, in the
following manner: (i) if the Securities are listed on any national securities
exchange, in compliance with the requirements of the principal securities
exchange on which the Securities are listed or (ii) if the Securities are not
listed on any national securities exchange, from the Outstanding Securities not
previously called for redemption pro rata, by lot or by such other method as the
Trustee considers to be fair and appropriate and which may provide for the
selection for redemption of portions (equal to $1,000 or any integral multiple
thereof of $1,000) of the principal amount of any Security to be redeemed.

          In any proration pursuant to this Section 1104, the Trustee shall make
such adjustments, reallocations and eliminations as it shall deem proper to the
end that the

                                     -139-
<PAGE>

principal amount of Securities so prorated shall be $1,000 or a multiple
thereof, by increasing or decreasing or eliminating the amount which would be
allocable to any Holder on the basis of exact proportion by an amount not
exceeding $1,000. The Trustee in its discretion may determine the particular
Securities (if there are more than one) registered in the name of any Holder
which are to be redeemed, in whole or in part. No Securities of a principal
amount of $1,000 or less shall be redeemed in part.

          The Trustee shall promptly notify the Company and the Security
Registrar in writing of the Securities selected for redemption and, in the case
of any Securities selected for partial redemption, the principal amount thereof
to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Securities shall relate, in
the case of any Security redeemed or to be redeemed only in part, to the portion
of the principal amount of such Security which has been or is to be redeemed.

SECTION 1105.  Notice of Redemption.
               --------------------

          Notice of redemption shall be given by first-class mail, postage
prepaid, mailed within the time periods specified in Section 1101 to each Holder
of Securities to be redeemed, at his address appearing in the Security Register.
Notices of redemption may not be conditional.

          All notices of redemption shall state:

          (1)  the Redemption Date;

          (2)  the Redemption Price [(or if not then ascertainable, the manner
     of calculation thereof)];

          (3)  if less than all the Outstanding Securities are to be redeemed,
     the identification (and, in the case of partial redemption, the principal
     amounts) of the particular Securities to be redeemed;

                                     -140-

          (4)  that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and that interest
     thereon will cease to accrue on and after said date; and

          (5)  the place or places where such Securities are to be surrendered
     for payment of the Redemption Price.

          Notice of redemption of Securities to be redeemed at the election 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.

SECTION 1106.  Deposit of Redemption Price.
               ---------------------------

          Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest (and Liquidated
Damages, if any) on, all the Securities which are to be redeemed on that date.

SECTION 1107.  Securities Payable on Redemption Date.
               -------------------------------------

          Notice of redemption having been given as afore said, the Securities
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest), such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
and Liquidated Damages, if any, to the Redemption Date; provided, however, that
                                                        --------  -------
installments of interest whose Stated Maturity is on or prior to the Redemption

Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
308.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate provided by the
Security.

SECTION 1108.  Securities Redeemed in Part.
               ---------------------------

          Any Security which is to be redeemed only in part shall be surrendered
at an office or agency of the Company designated for that purpose pursuant to
Section 1002 (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly authorized
in writing), and the Company shall execute, and the Trustee shall authenticate
and deliver to the Holder of such Security without service charge, a new
Security or Securities, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

applicable to this Section, the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities on the date the

purpose, such defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by the Outstanding Securities and

Indenture insofar as such

                                     -142-
<PAGE>

Securities are concerned (and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging the same), except for the following
which shall survive until otherwise terminated or discharged hereunder: (A) the
rights of Holders of such Securities to receive, solely from the trust fund
described in Section 1204 and as more fully set forth in such Section, payments
in respect of the principal of (and premium, if any) and interest (and

SECTION 1203.  Covenant Defeasance.
               -------------------

          Upon the Company's exercise of the option provided in Section 1201
applicable to this Section, (i) the Company shall be released from its

(with respect to any of Sections 1005 through 1023, inclusive), 501(6) and
501(7) shall not be deemed to be a Default or an Event of Default on and after
the date the conditions set forth below are satisfied (hereinafter, "covenant
defeasance"). For this purpose, such covenant defeasance means that the Company
may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section or Clause whether directly
or indirectly by reason of any reference elsewhere herein to any such Section or
Clause or by reason of any reference in any such Section or Clause to any other
provision herein or in any other document, but the remainder of this Indenture

<PAGE>

          The following shall be the conditions to application of either Section
1202 or Section 1203 to the then Outstanding Securities:

          (1)  the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders of the Securities, cash in U.S. dollars,
     non-callable Government Securities, or a combination thereof, in such
     amounts as will be 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 the principal of, or interest and
     premium and Liquidated Damages, if any, on the Outstanding Securities on
     the Stated Maturity or on the applicable Redemption Date, as the case may
     be, and the Company must specify whether the Securities are being defeased
     to Maturity or to a particular Redemption Date;

          (2)  in the case of an election under Section 1202, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the Trustee
     confirming that (a) the Company has received from, or there has been
     published by, the Internal Revenue Service a ruling or (b) since the date
     of this Indenture, there has been a change in the applicable Federal income
     tax law, in either case to the effect that, and based thereon such Opinion
     of Counsel shall confirm that, the Holders of the Outstanding Securities
     will not recognize income, gain or loss for Federal income tax purposes as
     a result of such deposit, defeasance and discharge and will be subject to
     Federal income tax on the same amounts, the same manner and at the same
     times as would have been the case if such deposit, defeasance and discharge
     had not occurred;

          (3)  in the case of an election under Section 1203, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the Trustee
     confirming that the Holders of the Outstanding Securities will not
     recognize income, gain or loss for Federal income tax purposes as a result
     of such covenant defeasance and will be subject to Federal income tax on
     the same amounts, in the same manner and at the same times as would have
     been the case if such covenant defeasance had not occurred;

                                     -144-
<PAGE>

          (4)  no Default or Event of Default shall have occurred and be
     continuing either: (a) on the date of such deposit (other than a Default or
     Event of Default resulting from the borrowing of funds to be applied to
     such deposit); or (b) insofar as Events of Default from bankruptcy or
     insolvency events are concerned, at any time in the period ending on the
     91st day after the date of deposit;

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

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

          (7)  the Company shall deliver to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     relating to the defeasance under Section 1202 or the covenant defeasance
     under Section 1203 (as the case may be) have been complied with.

SECTION 1205.  Deposited Money and U.S. Government Obligations to be Held in
               -------------------------------------------------------------
               Trust; Other Miscellaneous Provisions.
               --------------------------------------

          Subject to the provisions of the last paragraph of Section 1003, all
money and Government Securities (including the proceeds thereof) deposited with
the Trustee (or other qualifying trustee--collectively, for purposes of this
Section 1205, the "Trustee") pursuant to Section 1204 in respect of the
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities,
of all sums due and to become due thereon in respect of principal (and

                                     -145-
<PAGE>

(premium, if any) and any interest (and Liquidated Damages, if any), but
such money need not be segregated from other funds except to the extent required
by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Securities
deposited pursuant to Section 1204 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities.

          Anything in this Article Twelve to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Securities held by it as provided in Section
1204 which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent defeasance or covenant defeasance.

SECTION 1206.  Reinstatement.
               -------------

          If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 1202 or 1203 by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to this Article Twelve until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance with Section 1202 or 1203;
provided, however, that if the Company makes any payment of principal of (and
--------  -------
premium, if any) or inter est (and Liquidated Damages, if any) on the Securities
following the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money held by the Trustee or the Paying Agent.

SECTION 1207.  Qualifying Trustee.
               ------------------

          Any trustee appointed pursuant to Section 1204 for the purpose of
holding trust funds deposited pursuant to

                                     -146-
<PAGE>

that Section shall be appointed under an agreement in form acceptable to the
Trustee and shall provide to the Trustee a certificate of such trustee, upon
which certificate the Trustee shall be entitled to conclusively rely, that all
conditions precedent provided for herein to the related defeasance or covenant
defeasance have been complied with. In no event shall the Trustee be liable for
any acts or omissions of said trustee.

(whether by declaration or otherwise) pursuant to Section 502 hereof, no
Collateral shall be released except as permitted by the provisions of the
Security Documents, and no release of Collateral in contravention of this
Section 1303(b) shall be effective as against the Holders.

hereunder or under the Security Documents or which are specified in any Security
Document, including without limitation, the right to hold any Collateral in the
name of, registered to, or in the physical possession of such Joint Collateral
Agent, for the ratable benefit of the Holders. Each such Joint Collateral Agent

Trustee may deem expedient to preserve or protect its interests and the
interests of the Holders in the Collateral (including power to institute and
maintain suits or proceedings to restrain the enforcement of or compliance with
any legislative or other governmental enactment, rule or order that may be
unconstitutional or otherwise invalid if the enforcement of, or compliance with,

discretion and without the consent of the Holders, on behalf of the Holders,

or protect its interests and the interests of the Trustee, the Holders, the
Joint Collateral Agent or the Escrow Agent in the Collateral (including power to

compliance with any legislative or other governmental enactment, rule or order

expressly provided in this Indenture and the Security Documents. None of the
Trustee, the Joint Collateral Agent, or the Escrow Agent shall be liable to any
Person, except for their negligence (gross negligence in the case of the Escrow
Agent and the Joint Collateral Agent) or wilful misconduct, for failure to
collect or realize upon any and all of the Collateral, or for any delay in so
doing nor shall the Trustee, the Joint Collateral Agent and the Escrow Agent be
under any duty to take any action whatsoever with regard thereto except as
expressly provided in this Indenture and in the Security Documents. The Trustee,
the Joint Collateral Agent and the Escrow Agent shall have no duty to comply
with any recording, filing, or other legal requirements necessary to establish

                    i.  at the time the buy order was originated, the Transferee
               was outside the United States or the Owner and any person acting
               on its behalf reasonably believed that the Transferee was outside
               the United States, or

                    ii. the transaction is being executed in, on or through the
               facilities of the Eurobond market, as regulated by the
               Association of International Bond Dealers, or another designated
               offshore securities market and neither the Owner nor any person
               acting on its behalf knows that the transaction has been
               prearranged with a buyer in the United States;

               d.   no directed selling efforts have been made in the United
          States by or on behalf of the Owner or any affiliate thereof;

          registration requirements of the Securities Act.

2.   Rule 144 Transfers. If the transfer is being effected pursuant to Rule 144:

          one year (computed in accordance with paragraph (d) of Rule 144) has

          2.   Registration Under the Securities Act.

     (a)  Except as set forth in Section 2(b) below, the Company agrees to file
  under the Securities Act, as soon as practicable, but no later than 105 days
  after the Closing Date, a registration statement relating to an offer to
  exchange (such registration statement, the

                                       3
<PAGE>

  "Exchange Registration Statement", and such offer, the "Exchange Offer") any
  and all of the Securities for a like aggregate principal amount of debt
  securities issued by the Company, which debt securities are substantially
  identical to the Securities (and are entitled to the benefits of a trust
  indenture which is substantially identical to the Indenture or is the
  Indenture and which has been qualified under the Trust Indenture Act), except
  that they have been registered pursuant to an effective registration statement
  under the Securities Act and do not contain provisions for the additional
  interest contemplated in Section 2(c) below (such new debt securities
  hereinafter called "Exchange Securities"). The Company agrees to use its
  reasonable best efforts to cause the Exchange Registration Statement to become
  effective under the Securities Act as soon as practicable, but no later than
  225 days after the Closing Date. The Exchange Offer will be registered under
  the Securities Act on the appropriate form and will comply with all applicable
  tender offer rules and regulations under the Exchange Act. The Company further
  agrees to use its reasonable best efforts to commence and complete the
  Exchange Offer promptly, but no later than 45 days after such Exchange
  Registration Statement has become effective, hold the Exchange Offer open for
  at least 20 business days and exchange Exchange Securities for all Registrable
  Securities that have been properly tendered and not validly withdrawn on or
  prior to the expiration of the Exchange Offer. The Exchange Offer will be
  deemed to have been "completed" only if the debt securities received by
  holders other than Restricted Holders in the Exchange Offer for Registrable
  Securities are, upon receipt, transferable by each such holder without
  restriction under the Securities Act and the Exchange Act (except for the
  requirement to deliver a prospectus included in the Exchange Registration
  Statement applicable to resales by any broker-dealer of Exchange Securities
  received by such broker-dealer pursuant to an Exchange Offer in exchange for
  Registrable Securities other than those acquired by the broker-dealer directly
  from the Company) and without material restrictions under the blue sky or
  securities laws of a substantial majority of the States of the United States
  of America. The Exchange Offer shall be deemed to have been completed upon the
  earlier to occur of (i) the Company having exchanged the Exchange Securities
  for all outstanding Registrable Securities pursuant to the Exchange Offer and
  (ii) the Company having exchanged, pursuant to the Exchange Offer, Exchange
  Securities for all Registrable Securities that have been properly tendered and
  not withdrawn before the expiration of the Exchange Offer, which shall be on a
  date that is at least 30 days following the commencement of the Exchange
  Offer. The Company agrees (x) to include in the Exchange Registration
  Statement a prospectus for use in any resales by any holder of Exchange
  Securities that is a broker-dealer and (y) to keep such Exchange Registration
  Statement effective for a period (the "Resale Period") beginning when Exchange
  Securities are first issued in the Exchange Offer and ending upon the earlier
  of the expiration of the 180th day after the Exchange Offer has been completed
  or such time as such broker-dealers no longer own any Registrable Securities.
  With respect to such Exchange Registration Statement, such holders shall have
  the benefit of the rights of indemnification and contribution set forth in
  Sections 6(a), (c), (d) and (e) hereof.

     (b) (A)  If (i) on or prior to the time the Exchange Offer is completed,
  existing Commission interpretations are changed such that the debt securities
  received by holders other than Restricted Holders in the Exchange Offer for
  Registrable Securities are not or would not be, upon receipt, transferable by
  each such holder without restriction under the Securities Act, (ii) the
  Exchange Offer has not been completed within 270 days following the Closing
  Date or (iii) the Exchange Offer is not available to any holder of the
  Securities, the Company shall, in lieu of (or, in the case of clause (iii), in
  addition to) conducting the Exchange Offer contemplated by Section 2(a), file
  under the Securities Act as soon as practicable, but no later than the later
  of 30 days after the time such obligation to file arises,

                                       4
<PAGE>

  a "shelf" registration statement providing for the registration of, and the
  sale on a continuous or delayed basis by the holders of, all of the
  Registrable Securities, pursuant to Rule 415 or any similar rule that may be
  adopted by the Commission (such filing, the "Shelf Registration" and such
  registration statement, the "Shelf Registration Statement"). The Company
  agrees to use its reasonable best efforts (x) to cause the Shelf Registration
  Statement to become or be declared effective no later than 120 days after such
  Shelf Registration Statement is filed and to keep such Shelf Registration
  Statement continuously effective for a period ending on the earlier of (i) the
  second anniversary of the Effective Time or (ii) such time as there are no
  longer any Registrable Securities outstanding, provided, however, that no
  holder shall be entitled to be named as a selling security holder in the Shelf
  Registration Statement or to use the prospectus forming a part thereof for
  resales of Registrable Securities unless such holder is an Electing Holder,
  and (y) after the Effective Time of the Shelf Registration Statement, promptly
  upon the request of any holder of Registrable Securities that is not then an
  Electing Holder, to take any action reasonably necessary to enable such holder
  to use the prospectus forming a part thereof for resales of Registrable
  Securities, including, without limitation, any action necessary to identify
  such holder as a selling security holder in the Shelf Registration Statement,
  provided, further, that nothing in this clause (y) shall relieve any such
  holder of the obligation to return a completed and signed Notice and
  Questionnaire to the Company in accordance with Section 3(d)(iii) hereof. The
  Company further agrees to supplement or make amendments to the Shelf
  Registration Statement, as and when required by the rules, regulations or
  instructions applicable to the registration form used by the Company for such
  Shelf Registration Statement or by the Securities Act or rules and regulations
  thereunder for shelf registration, and the Company agrees to furnish to each
  Electing Holder copies of any such supplement or amendment prior to its being
  used or promptly following its filing with the Commission.

     (B)  Notwithstanding the foregoing, following the initial effectiveness of
  the Shelf Registration Statement, the Company may postpone, for a period not
  to exceed 30 days, supplementing or amending the Shelf Registration Statement
  if (i) the Company is in possession of material non-public information related
  to a proposed financing, recapitalization, acquisition, business combination
  or other material transaction and the Board of Directors of the Company
  determines (in good faith in a written resolution) that disclosure of such
  information would have a material adverse effect on the business or operations
  of the Company or any of its subsidiaries and disclosure of such information
  is not otherwise required by law and (ii) the Company delivers notice (which
  shall include a copy of the resolution of the Board of Directors with respect
  to such determination) to the Electing Holders and any placement agent or
  underwriting as contemplated by Section 3(d)(viii)(F) to the effect that
  Electing Holders may not make offers or sales under the Shelf Registration
  Statement; provided, however, that the Company may deliver only two such
  notices within any twelve-month period; it being understood for the avoidance
  of doubt that in no event shall the Company be permitted to extend the time
  period within which it must file the Shelf Registration Statement pursuant to
  Section 2(b)(A) or the time period within which it must cause the Shelf
  Registration Statement to become or be declared effective pursuant to Section
  2(b)(A)(x).  Promptly upon the earlier of (x) public disclosure of such
  material non-public information, (y) the date on which such non-public
  information is no longer material and (z) 30 days after the notice is given by
  the Company pursuant to clause (ii) above, the Company shall supplement or
  amend the Shelf Registration Statement as required by Section 3(e) and give
  notice to the Electing Holders that offers and sales under the Shelf
  Registration Statement may be resumed.

                                       5
<PAGE>

     (c)  In the event that (i) the Company has not filed the Exchange
  Registration Statement or Shelf Registration Statement on or before the date
  on which such registration statement is required to be filed pursuant to
  Section 2(a) or 2(b), respectively, or (ii) such Exchange Registration
  Statement or Shelf Registration Statement has not become effective or been
  declared effective by the Commission on or before the date on which such
  registration statement is required to become or be declared effective pursuant
  to Section 2(a) or 2(b), respectively, or (iii) the Exchange Offer has not
  been completed within 45 days after the initial effective date of the Exchange
  Registration Statement relating to the Exchange Offer (if the Exchange Offer
  is then required to be made) or (iv) any Exchange Registration Statement or
  Shelf Registration Statement required by Section 2(a) or 2(b) hereof is filed
  and declared effective but shall thereafter either be withdrawn by the Company
  or shall become subject to an effective stop order issued pursuant to Section
  8(d) of the Securities Act suspending the effectiveness of such registration
  statement (except as specifically permitted herein) without being succeeded
  immediately by an additional registration statement filed and declared
  effective (each such event referred to in clauses (i) through (iv), a
  "Registration Default" and each period during which a Registration Default has
  occurred and is continuing, a "Registration Default Period"), then, as
  liquidated damages for such Registration Default, subject to the provisions of
  Section 9(b), special interest ("Special Interest"), in addition to the Base
  Interest, shall accrue at a per annum rate of 0.50% for the first 90 days of
  the Registration Default Period, at a per annum rate of 1.0% for the second 90
  days of the Registration Default Period, and at a per annum rate of 1.0%
  thereafter for the remaining portion of the Registration Default Period.
  Following the cure of all Registration Defaults, the accrual of such special
  interest will cease.

     (d)  The Company shall take all actions necessary or advisable to be taken
  by it to ensure that the transactions contemplated herein are effected as so
  contemplated.

     (e)  Any reference herein to a registration statement as of any time shall
  be deemed to include any document incorporated, or deemed to be incorporated,
  therein by reference as of such time and any reference herein to any post-
  effective amendment to a registration statement as of any time shall be deemed
  to include any document incorporated, or deemed to be incorporated, therein by
  reference as of such time.

     3.   Registration Procedures.

          If the Company files a registration statement pursuant to Section 2(a)
or Section 2(b), the following provisions shall apply:

     (a)  At or before the Effective Time of the Exchange Offer or the Shelf
  Registration, as the case may be, the Company shall qualify the Indenture
  under the Trust Indenture Act of 1939.

     (b)  In the event that such qualification would require the appointment of
  a new trustee under the Indenture, the Company shall appoint a new trustee
  thereunder pursuant to the applicable provisions of the Indenture.

     (c)  In connection with the Company's obligations with respect to the
  registration of Exchange Securities as contemplated by Section 2(a) (the
  "Exchange Registration"), if applicable, the Company shall, as soon as
  practicable (or as otherwise specified):

               (i)  prepare and file with the Commission, as soon as practicable
          but no later than 105 days after the Closing Date, an Exchange
          Registration Statement on any

                                       6
<PAGE>

          form which may be utilized by the Company and which shall permit the
          Exchange Offer and resales of Exchange Securities by broker-dealers
          during the Resale Period to be effected as contemplated by Section
          2(a), and use its reasonable best efforts to cause such Exchange
          Registration Statement to become effective as soon as practicable
          thereafter, but no later than 225 days after the Closing Date;

               (ii)  as soon as practicable prepare and file with the Commission
          such amendments and supplements to such Exchange Registration
          Statement and the prospectus included therein as may be necessary to
          effect and maintain the effectiveness of such Exchange Registration
          Statement for the periods and purposes contemplated in Section 2(a)
          hereof and as may be required by the applicable rules and regulations
          of the Commission and the instructions applicable to the form of such
          Exchange Registration Statement, and promptly provide each broker-
          dealer holding Exchange Securities with such number of copies of the
          prospectus included therein (as then amended or supplemented), in
          conformity in all material respects with the requirements of the
          Securities Act and the Trust Indenture Act and the rules and
          regulations of the Commission thereunder, as such broker-dealer
          reasonably may request in writing to the Company prior to the
          expiration of the Resale Period, for use in connection with resales of
          Exchange Securities;

               (iii) promptly notify each broker-dealer that has requested or
          received copies of the prospectus included in such Exchange
          Registration Statement, and confirm such advice in writing, (A) when
          such Exchange Registration Statement or the prospectus included
          therein or any prospectus amendment or supplement or post-effective
          amendment has been filed, and, with respect to such Exchange
          Registration Statement or any post-effective amendment, when the same
          has become effective, (B) of any comments by the Commission and by the
          blue sky or securities commissioner or regulator of any state with

          for additional information, (C) of the issuance by the Commission of
          any stop order suspending the effectiveness of such Exchange
          Registration Statement or the initiation or threatening of any

          or (F) at any time during the Resale Period when a prospectus is
          required to be delivered under the Securities Act, that such Exchange
          Registration Statement, prospectus, prospectus amendment or supplement
          or post-effective amendment does not conform in all material respects
          to the applicable requirements of the Securities Act and the Trust
          Indenture Act and the rules and regulations of the Commission
          thereunder or contains an untrue statement of a material fact or omits

          to make the statements therein not misleading in light of the
          circumstances then existing;

               (iv)  in the event that the Company would be required, pursuant
          to Section 3(e)(iii)(F) above, to notify any broker-dealers holding
          Exchange Securities, without unreasonable delay to prepare and furnish
          to each such holder a reasonable number of copies of a prospectus
          supplemented or amended so that, as thereafter delivered to purchasers
          of such Exchange Securities during the Resale Period, such

                                       7
<PAGE>

          prospectus shall conform in all material respects to the applicable
          requirements of the Securities Act and the Trust Indenture Act and the
          rules and regulations of the Commission thereunder and shall not
          contain an untrue statement of a material fact or omit to state a
          material fact required to be stated therein or necessary to make the
          statements therein not misleading in light of the circumstances then
          existing;

               (v)    use its reasonable best efforts to obtain the withdrawal

               (vi)   use its reasonable best efforts to (A) register or qualify
          the Exchange Securities under the securities laws or blue sky laws of
          such jurisdictions as are contemplated by Section 2(a) no later than
          the commencement of the Exchange Offer, (B) keep such registrations or
          qualifications in effect and comply with such laws so as to permit the
          continuance of offers, sales and dealings therein in such
          jurisdictions until the expiration of the Resale Period and (C) take
          any and all other actions as may be reasonably necessary or advisable
          to enable each broker-dealer holding Exchange Securities to consummate
          the disposition thereof in such jurisdictions; provided, however, that
          the Company shall not be responsible for any filing obligations that
          such broker-dealer may incur as such under the laws of such
          jurisdiction; and provided, further, however, that the Company shall
          not be required for any such purpose to (1) qualify as a foreign
          corporation in any jurisdiction wherein it would not otherwise be
          required to qualify but for the requirements of this Section 3(c)(vi),
          (2) consent to general service of process in any such jurisdiction or
          (3) make any changes to its certificate of incorporation or by-laws or
          any agreement between it and its stockholders;

               (vii)  use its reasonable best efforts to obtain the consent or
          approval of each governmental agency or authority, whether federal,

          the Company and its subsidiaries complying with Section 11(a) of the
          Securities Act (including, at the option of the Company, Rule 158

          material respects, (E) of the receipt by the Company of any
          notification with respect to the suspension of the qualification of
          the Registrable Securities for sale in any jurisdiction or the
          initiation or threatening of any proceeding for such purpose, or (F)
          if at any time when a prospectus is required to be delivered under the
          Securities Act, that such Shelf Registration Statement, prospectus,

          of such Shelf Registration Statement (excluding exhibits thereto and
          documents incorporated by reference therein unless specifically so
          requested by such Electing Holder, agent or underwriter, as the case
          may be) and of the prospectus included in such Shelf Registration

  the disposition of Registrable Securities pursuant to the Shelf Registration
  Statement applicable to such Registrable Securities until such Electing Holder
  shall have received copies of such amended or supplemented prospectus, and if
  so directed by the Company, such Electing Holder shall deliver to the Company
  (at the Company's expense) all copies, other than permanent file copies, then
  in such Electing Holder's possession of the prospectus covering such
  Registrable Securities at the time of receipt of such notice.

     (f) In the event of a Shelf Registration, in addition to the information
  required to be provided by each Electing Holder in its Notice and
  Questionnaire, the Company may require such Electing Holder to furnish to the
  Company such additional information regarding such Electing Holder and such
  Electing Holder's intended method of distribution of Registrable Securities as
  may be required in order to comply with the Securities Act. Each such Electing
  Holder agrees to notify the Company as promptly as practicable of any
  inaccuracy or change in information previously furnished by such Electing
  Holder to the Company or of the occurrence of any event in either case as a
  result of which any prospectus relating to such Shelf Registration contains or
  would contain an untrue statement of a material fact regarding such Electing
  Holder or such Electing Holder's intended method of disposition of such
  Registrable Securities or omits to state any material fact regarding such
  Electing

                                       14

  Holder or such Electing Holder's intended method of disposition of such
  Registrable Securities required to be stated therein or necessary to make the
  statements therein not misleading in light of the circumstances then existing,
  and promptly to furnish to the Company any additional information required to
  correct and update any previously furnished information or required so that
  such prospectus shall not contain, with respect to such Electing Holder or the
  disposition of such Registrable Securities, an untrue statement of a material
  fact or omit to state a material fact required to be stated therein or
  necessary to make the statements therein not misleading in light of the
  circumstances then existing.

     (g) Until the expiration of two years after the Closing Date, the Company
  will not, and will not permit any of its "affiliates" (as defined in Rule 144)
  to, resell any of the Securities that have been reacquired by any of them
  except pursuant to an effective registration statement under the Securities
  Act.

Registrable Securities or any placement or sales agent therefor or underwriter
thereof, the Company shall reimburse such person for the full amount of the

Securities being registered shall pay all agency fees and commissions and
underwriting discounts and commissions attributable to the sale of such
Registrable Securities and the fees and disbursements of any counsel or other
advisors or experts retained by such holders (severally or jointly), other than

     5.  Representations and Warranties.

         The Company represents and warrants to, and agrees with, each Purchaser
and each of the holders from time to time of Registrable Securities that:

     (a) Each registration statement covering Registrable Securities and each
  prospectus (including any preliminary or summary prospectus) contained therein
  or furnished pursuant to Section 3(d) or Section 3(c) hereof and any further
  amendments or supplements to any such registration statement or prospectus,
  when it becomes effective or is filed with the Commission, as the case may be,
  and, in the case of an underwritten offering of Registrable Securities, at the
  time of the closing under the underwriting agreement relating thereto, will
  conform in all material respects to the requirements of the Securities Act and
  the Trust Indenture Act and the rules and regulations of the Commission
  thereunder and will not contain an untrue statement of a material fact or omit
  to state a material fact required to be stated therein or necessary to make
  the statements therein, and with respect to any prospectus at the time of the
  closing under any applicable underwriting agreement, in light of the
  circumstances then existing, not misleading; and at all times subsequent to
  the applicable Effective Time when a prospectus would be required to be
  delivered under the Securities Act, other than (A) from (i) such time as a
  notice has been given to holders of Registrable Securities pursuant to Section
  3(d)(viii)(F) or Section 3(c)(iii)(F) hereof until (ii) such time as the
  Company furnishes an amended or supplemented prospectus pursuant to Section
  3(e) or Section 3(c)(iv) hereof or (B) during any suspension of offering and
  sale pursuant to Section 2(b)(B) hereof, each such registration statement, and
  each prospectus (including any summary prospectus) contained therein or
  furnished pursuant to Section 3(d) or Section 3(c) hereof, as then amended or
  supplemented, will conform in all material respects to the requirements of the
  Securities Act and the Trust Indenture Act and the rules and regulations of
  the Commission thereunder and will not contain an untrue statement of a
  material fact or omit to state a material fact required to be stated therein
  or necessary to make the statements therein not misleading in the light of the
  circumstances then existing; provided, however, that this representation and
  warranty shall not apply to any statements or omissions made in reliance upon
  and in conformity with information furnished in writing to the Company by a
  holder of Registrable Securities expressly for use therein.

     (b) Any documents incorporated by reference in any prospectus referred to
  in Section 5(a) hereof, when they become or became effective or are or were
  filed with the Commission, as the case may be, will conform or conformed in
  all material respects to the requirements of the Securities Act or the
  Exchange Act, as applicable, and none of such documents will contain or
  contained an untrue statement of a material fact or will omit or omitted to
  state a material fact required to be stated therein or necessary to make the
  statements therein, and with respect to any prospectus at the time of the
  closing under any applicable underwriting agreement, in light of the
  circumstances then existing, not misleading; provided, however, that this
  representation and warranty shall not apply to any

                                       16
<PAGE>

  statements or omissions made in reliance upon and in conformity with
  information furnished in writing to the Company by a holder of Registrable
  Securities expressly for use therein.

     (c) The compliance by the Company with all of the provisions of this
  Exchange and Registration Rights Agreement and the consummation of the
  transactions herein contemplated will not conflict with or result in a breach
  of any of the terms or provisions of, or constitute a default under, any
  indenture, mortgage, deed of trust, loan agreement or other agreement or
  instrument to which the Company or any subsidiary of the Company is a party or
  by which the Company or any subsidiary of the Company is bound or to which any
  of the property or assets of the Company or any subsidiary of the Company is
  subject, except for such conflicts, breaches, violations or defaults which
  would not have, individually or in the aggregate, a material adverse effect on
  the condition (financial or other), business, properties or results of
  operations of the Company and its subsidiaries, taken as a whole, or a
  material adverse effect on the ability of the Company to perform its
  obligations under this Agreement nor will such action result in any violation
  of the provisions of the certificate of incorporation, as amended, or the by-
  laws of the Company or any statute or any order, rule or regulation of any
  court or governmental agency or body having jurisdiction over the Company or
  any subsidiary of the Company or any of their properties; and no consent,
  approval, authorization, order, registration or qualification of or with any
  such court or governmental agency or body is required for the consummation by
  the Company of the transactions contemplated by this Exchange and Registration
  Rights Agreement, except the registration under the Securities Act of the
  Securities, qualification of the Indenture under the Trust Indenture Act and
  such consents, approvals, authorizations, registrations or qualifications as
  may be required under State securities or blue sky laws in connection with the
  offering and distribution of the Securities.

     (d) This Exchange and Registration Rights Agreement has been duly
  authorized, executed and delivered by the Company.

     6.  Indemnification.

     (a) Indemnification by the Company. The Company will indemnify and hold
  harmless each of the holders of Registrable Securities included in an Exchange
  Registration Statement, each of the Electing Holders of Registrable Securities
  included in a Shelf Registration Statement and each person who participates as
  a placement or sales agent or as an underwriter in any offering or sale of
  such Registrable Securities against any losses, claims, damages or
  liabilities, joint or several, to which such holder, agent or underwriter may
  become subject under the Securities Act or otherwise, insofar as such losses,
  claims, damages or liabilities (or actions in respect thereof) arise out of or
  are based upon an untrue statement or alleged untrue statement of a material
  fact contained in any Exchange Registration Statement or Shelf Registration
  Statement, as the case may be, under which such Registrable Securities were
  registered under the Securities Act, or any preliminary, final or summary
  prospectus contained therein or furnished by the Company to any such holder,
  Electing Holder, agent or underwriter, or any amendment or supplement thereto,
  or arise out of or are based upon the omission or alleged omission to state
  therein a material fact required to be stated therein or necessary to make the
  statements therein, and with respect to any prospectus at the time of the
  closing under any applicable underwriting agreement, in light of the
  circumstances then existing, not misleading, and will reimburse such holder,
  such Electing Holder, such agent and such underwriter for any legal or other
  expenses reasonably incurred by them in connection with investigating or
  defending any such action or claim as such expenses are incurred; provided,
  however, that the Company

                                       17
<PAGE>

  shall not be liable to any such person in any such case to the extent that any
  such loss, claim, damage or liability arises out of or is based upon an untrue
  statement or alleged untrue statement or omission or alleged omission made in
  such registration statement, or preliminary, final or summary prospectus, or
  amendment or supplement thereto, in reliance upon and in conformity with
  written information furnished to the Company by such person expressly for use
  therein.

     (b) Indemnification by the Holders and any Agents and Underwriters. The
  Company may require, as a condition to including any Registrable Securities in
  any Shelf Registration Statement filed pursuant to Section 2(b) hereof and to
  entering into any underwriting agreement with respect thereto, that the
  Company shall have received an undertaking reasonably satisfactory to it from
  the Electing Holder of such Registrable Securities and from each underwriter
  named in any such underwriting agreement, severally and not jointly, to (i)
  indemnify and hold harmless the Company, and all other holders of Registrable
  Securities, against any losses, claims, damages or liabilities (or actions in
  respect thereof) to which the Company or such other holders of Registrable
  Securities may become subject, under the Securities Act or otherwise, insofar
  as such losses, claims, damages or liabilities (or actions in respect thereof)
  arise out of or are based upon an untrue statement or alleged untrue statement
  of a material fact contained in such registration statement, or any
  preliminary, final or summary prospectus contained therein or furnished by the
  Company to any such Electing Holder, agent or underwriter, or any amendment or
  supplement thereto, or arise out of or are based upon the omission or alleged
  omission to state therein a material fact required to be stated therein or
  necessary to make the statements therein not misleading, in each case to the
  extent, but only to the extent, that such untrue statement or alleged untrue
  statement or omission or alleged omission was made in reliance upon and in
  conformity with written information furnished to the Company by such Electing
  Holder or underwriter expressly for use therein, and (ii) reimburse the
  Company for any legal or other expenses reasonably incurred by the Company in
  connection with investigating or defending any such action or claim as such
  expenses are incurred; provided, however, that no such Electing Holder shall
  be required to undertake liability to any person under this Section 6(b) for
  any amounts in excess of the dollar amount of the proceeds to be received by
  such Electing Holder from the sale of such Electing Holder's Registrable
  Securities pursuant to such registration.

     (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party
  under subsection (a) or (b) above of written notice of the commencement of any
  action, such indemnified party shall, if a claim in respect thereof is to be
  made against an indemnifying party pursuant to the indemnification provisions
  of or contemplated by this Section 6, notify such indemnifying party in
  writing of the commencement of such action; but the omission so to notify the
  indemnifying party shall not relieve it from any liability which it may have
  to any indemnified party otherwise than under the indemnification provisions
  of or contemplated by Section 6(a) or 6(b) hereof. In case any such action
  shall be brought against any indemnified party and it shall notify an
  indemnifying party of the commencement thereof, such indemnifying party shall
  be entitled to participate therein and, to the extent that it shall wish,
  jointly with any other indemnifying party similarly notified, to assume the
  defense thereof, with counsel reasonably satisfactory to such indemnified
  party (who shall not, except with the consent of the indemnified party, be
  counsel to the indemnifying party), and, after notice from the indemnifying
  party to such indemnified party of its election so to assume the defense
  thereof, such indemnifying party shall not be liable to such indemnified party
  for any legal expenses of other counsel or any other expenses, in each case
  subsequently incurred by such indemnified party, in connection with the
  defense thereof

                                       18
<PAGE>

  other than reasonable costs of investigation. No indemnifying party shall,
  without the written consent of the indemnified party, effect the settlement or
  compromise of, or consent to the entry of any judgment with respect to, any
  pending or threatened action or claim in respect of which indemnification or
  contribution may be sought hereunder (whether or not the indemnified party is
  an actual or potential party to such action or claim) unless such settlement,
  compromise or judgment (i) includes an unconditional release of the
  indemnified party from all liability arising out of such action or claim and
  (ii) does not include a statement as to or an admission of fault, culpability
  or a failure to act by or on behalf of any indemnified party.

     (d) Contribution. If for any reason the indemnification provisions
  contemplated by Section 6(a) or Section 6(b) are unavailable to or
  insufficient to hold harmless an indemnified party in respect of any losses,
  claims, damages or liabilities (or actions in respect thereof) referred to
  therein, then each indemnifying party shall contribute to the amount paid or
  payable by such indemnified party as a result of such losses, claims, damages
  or liabilities (or actions in respect thereof) in such proportion as is
  appropriate to reflect the relative fault of the indemnifying party and the
  indemnified party 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 such indemnifying party and indemnified party shall be determined by
  reference to, among other things, whether the untrue or alleged untrue
  statement of a material fact or omission or alleged omission to state a
  material fact relates to information supplied by such indemnifying party or by
  such indemnified party, and the parties' relative intent, knowledge, access to
  information and opportunity to correct or prevent such statement or omission.
  The parties hereto agree that it would not be just and equitable if
  contributions pursuant to this Section 6(d) were determined by pro rata
  allocation (even if the holders or any agents or underwriters or all of them
  were treated as one entity for such purpose) or by any other method of
  allocation which does not take account of the equitable considerations
  referred to in this Section 6(d). The amount paid or payable by an indemnified
  party as a result of the losses, claims, damages, or liabilities (or actions
  in respect thereof) referred to above shall be deemed to include any legal or
  other fees or expenses reasonably incurred by such indemnified party in
  connection with investigating or defending any such action or claim.
  Notwithstanding the provisions of this Section 6(d), no holder shall be
  required to contribute any amount in excess of the amount by which the dollar
  amount of the proceeds received by such holder from the sale of any
  Registrable Securities (after deducting any fees, discounts and commissions
  applicable thereto) exceeds the amount of any damages which such holder has
  otherwise been required to pay by reason of such untrue or alleged untrue
  statement or omission or alleged omission, and no underwriter shall be
  required to contribute any amount in excess of the amount by which the total
  price at which the Registrable Securities underwritten by it and distributed
  to the public were offered to the public exceeds the amount of any damages
  which such underwriter has otherwise been required to pay by reason of such
  untrue or alleged untrue statement or omission or alleged omission. No person
  guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
  the Securities Act) shall be entitled to contribution from any person who was
  not guilty of such fraudulent misrepresentation. The holders' and any
  underwriters' obligations in this Section 6(d) to contribute shall be several
  in proportion to the principal amount of Registrable Securities registered or
  underwritten, as the case may be, by them and not joint.

     (e) The obligations of the Company under this Section 6 shall be in
  addition to any liability which the Company may otherwise have and shall
  extend, upon the same terms and

                                       19
<PAGE>

  conditions, to each officer, director and partner of each holder, agent and
  underwriter and each person, if any, who controls any holder, agent or
  underwriter within the meaning of the Securities Act; and the obligations of
  the holders and any agents or underwriters contemplated by this Section 6
  shall be in addition to any liability which the respective holder, agent or
  underwriter may otherwise have and shall extend, upon the same terms and
  conditions, to each officer and director of the Company and to each person, if
  any, who controls the Company within the meaning of the Securities Act.

     7.  Underwritten Offerings.

     (a) Selection of Underwriters. If any of the Registrable Securities covered
  by the Shelf Registration are to be sold pursuant to an underwritten offering,
  the managing underwriter or underwriters thereof shall be designated by
  Electing Holders holding at least a majority in aggregate principal amount of
  the Registrable Securities to be included in such offering, provided that such
  designated managing underwriter or underwriters is or are reasonably
  acceptable to the Company.

     (b) Participation by Holders. Each holder of Registrable Securities hereby
  agrees with each other such holder that no such holder may participate in any
  underwritten offering hereunder unless such holder (i) agrees to sell such
  holder's Registrable Securities on the basis provided in any underwriting
  arrangements approved by the persons entitled hereunder to approve such
  arrangements and (ii) completes and executes all questionnaires, powers of
  attorney, indemnities, underwriting agreements and other documents reasonably
  required under the terms of such underwriting arrangements.

     8.  Rule 144.

         The Company covenants to the holders of Registrable Securities that to
the extent it shall be required to do so under the Exchange Act, the Company
shall timely file the reports required to be filed by it under the Exchange Act
or the Securities Act (including the reports under Section 13 and 15(d) of the
Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the
Commission under the Securities Act) and the rules and regulations adopted by
the Commission thereunder, and shall take such further action as any holder of
Registrable Securities may reasonably request, all to the extent required from
time to time to enable such holder to sell Registrable Securities without
registration under the Securities Act within the limitations of the exemption
provided by Rule 144 under the Securities Act, as such Rule may be amended from
time to time, or any similar or successor rule or regulation hereafter adopted
by the Commission. Upon the request of any holder of Registrable Securities in
connection with that holder's sale pursuant to Rule 144, the Company shall
deliver to such holder a written statement as to whether it has complied with
such requirements.

     9.  Miscellaneous.

     (a) No Inconsistent Agreements.  The Company represents, warrants,
  covenants and agrees that it has not granted, and shall not grant,
  registration rights with respect to Registrable Securities or any other
  securities which would be inconsistent with the terms contained in this
  Exchange and Registration Rights Agreement.

     (b) Specific Performance.  The parties hereto acknowledge that there would
  be no adequate remedy at law if the Company fails to perform any of its
  obligations hereunder and that the Purchasers and the holders from time to
  time of the Registrable Securities may be irreparably harmed by any such
  failure, and accordingly agree that the Purchasers and such

                                       20
<PAGE>

  holders, in addition to any other remedy to which they may be entitled at law
  or in equity, shall be entitled to compel specific performance of the
  obligations of the Company under this Exchange and Registration Rights
  Agreement in accordance with the terms and conditions of this Exchange and
  Registration Rights Agreement, in any court of the United States or any State
  thereof having jurisdiction.

     (c) Notices.  All notices, requests, claims, demands, waivers and other
  communications hereunder shall be in writing and shall be deemed to have been
  duly given when delivered by hand, if delivered personally or by courier, or
  three days after being deposited in the mail (registered or certified mail,
  postage prepaid, return receipt requested) as follows: If to the Company, to
  it at 955 Overland Court, San Dimas, California 91773, and if to a holder, to
  the address of such holder set forth in the security register or other records
  of the Company, or to such other address as the Company or any such holder may
  have furnished to the other in writing in accordance herewith, except that
  notices of change of address shall be effective only upon receipt.

     (d) Parties in Interest.  All the terms and provisions of this Exchange and
  Registration Rights Agreement shall be binding upon, shall inure to the
  benefit of and shall be enforceable by the parties hereto and the holders from
  time to time of the Registrable Securities and the respective successors and
  assigns of the parties hereto and such holders. In the event that any
  transferee of any holder of Registrable Securities shall acquire Registrable
  Securities, in any manner, whether by gift, bequest, purchase, operation of
  law or otherwise, such transferee shall, without any further writing or action
  of any kind, be deemed a beneficiary hereof for all purposes and such
  Registrable Securities shall be held subject to all of the terms of this
  Exchange and Registration Rights Agreement, and by taking and holding such
  Registrable Securities such transferee shall be entitled to receive the
  benefits of, and be conclusively deemed to have agreed to be bound by all of
  the applicable terms and provisions of this Exchange and Registration Rights
  Agreement. If the Company shall so request, any such successor, assign or
  transferee shall agree in writing to acquire and hold the Registrable
  Securities subject to all of the applicable terms hereof.

     (e) Survival.  The respective indemnities, agreements, representations,
  warranties and each other provision set forth in this Exchange and
  Registration Rights Agreement or made pursuant hereto shall remain in full
  force and effect regardless of any investigation (or statement as to the
  results thereof) made by or on behalf of any holder of Registrable Securities,
  any director, officer or partner of such holder, any agent or underwriter or
  any director, officer or partner thereof, or any controlling person of any of
  the foregoing, and shall survive delivery of and payment for the Registrable
  Securities pursuant to the Purchase Agreement and the transfer and
  registration of Registrable Securities by such holder and the consummation of
  an Exchange Offer.

     (f) Governing Law.  This Exchange and Registration Rights Agreement shall
  be governed by and construed in accordance with the laws of the State of New
  York.

     (g) Headings.  The descriptive headings of the several Sections and
  paragraphs of this Exchange and Registration Rights Agreement are inserted for
  convenience only, do not constitute a part of this Exchange and Registration
  Rights Agreement and shall not affect in any way the meaning or interpretation
  of this Exchange and Registration Rights Agreement.

     (h) Entire Agreement; Amendments.  This Exchange and Registration Rights
  Agreement and the other writings referred to herein (including the Indenture
  and the form of Securities) or delivered pursuant hereto which form a part
  hereof contain the entire

                                       21

  understanding of the parties with respect to its subject matter. This Exchange
  and Registration Rights Agreement supersedes all prior agreements and
  understandings between the parties with respect to its subject matter. This
  Exchange and Registration Rights Agreement may be amended and the observance
  of any term of this Exchange and Registration Rights Agreement may be waived
  (either generally or in a particular instance and either retroactively or
  prospectively) only by a written instrument duly executed by the Company and
  the holders of at least a majority in aggregate principal amount of the
  Registrable Securities at the time outstanding. Each holder of any Registrable
  Securities at the time or thereafter outstanding shall be bound by any
  amendment or waiver effected pursuant to this Section 9(h), whether or not any
  notice, writing or marking indicating such amendment or waiver appears on such
  Registrable Securities or is delivered to such holder.

     (i) Inspection.  For so long as this Exchange and Registration Rights
  Agreement shall be in effect, this Exchange and Registration Rights Agreement
  and, upon three days' notice, a complete list of the names and addresses of
  all the holders of Registrable Securities shall be made available for
  inspection and copying on any business day by any holder of Registrable
  Securities for proper purposes only (which shall include any purpose related
  to the rights of the holders of Registrable Securities under the Securities,
  the Indenture and this Agreement) at the offices of the Company at the address
  thereof set forth in Section 9(c) above and at the office of the Trustee under
  the Indenture.

     (j) Counterparts.  This agreement may be executed by the parties in
  counterparts, each of which shall be deemed to be an original, but all such
  respective counterparts shall together constitute one and the same instrument.

     If the foregoing is in accordance with your understanding, please sign and
return to us one for the Company and each of the Representatives plus one for
each counsel counterparts hereof, and upon the acceptance hereof by you, on
behalf of each of the Purchasers, this letter and such acceptance hereof shall
constitute a binding agreement between each of the Purchasers and the Company.
It is understood that your acceptance of this letter on behalf of each of the
Purchasers is pursuant to the authority set forth in a form of Agreement among
Purchasers, the form of which shall be submitted to the Company for examination
