the date of its authentication. The Securities shall be in registered form
without coupons and only in denominations of $1,000 and any integral multiples
thereof. The terms and provisions contained in the Securities shall constitute,
and are hereby expressly made, a part of this Indenture and, to the extent
applicable, the Company, the Guarantor and the Trustee, by their execution and
delivery of this Indenture, expressly agree to such terms and provisions and to
be bound thereby.

                  (b) Global Securities. Original Securities of any series
offered and sold (1) to QIBs in reliance on Rule 144A or (2) to Non-U.S. Persons
in reliance on Regulation S, in each case as provided in the Purchase Agreement,
shall be issued initially in the form of one or more Global Securities in
definitive, fully registered form without interest coupons and bearing the
Global Security Legend and Private Placement Legend, which shall be deposited on
behalf of the purchasers of the Original Securities represented thereby with the
Trustee, at its Houston, Texas office, as custodian for the Depositary (or with
such other custodian as the Depositary may direct), and registered in the name
of the Depositary or

<PAGE>
                                      -13-

a nominee of the Depositary, duly executed by the Company and authenticated by
the Trustee as hereinafter provided. The aggregate principal amount of the
Global Securities may from time to time be increased or decreased by adjustments
made on the records of the Trustee and the Depositary or its nominee as
hereinafter provided. Any endorsement of a Global Security to reflect the amount
of any increase or decrease in the aggregate principal amount of outstanding
Securities represented thereby shall be made by the Trustee or the Securities
Custodian, at the direction of the Trustee, in accordance with instructions
given by the Holder thereof as required by Section 2.06.

                  Members of, or participants in, the Depositary ("Agent
Members") shall have no rights under this Indenture with respect to any Global
Security held on their behalf by the Depositary or by the Trustee as the
custodian of the Depositary or under such Global Security, and the Depositary
may be treated by the Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner of such Global Security for all purposes
whatsoever. 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
the Depositary or impair, as between the Depositary and its Agent Members, the
operation of customary practices of such Depositary governing the exercise of
the rights of a holder of a beneficial interest in any Global Security.

                  (c) Temporary Global Securities. Securities offered and sold
in reliance on Regulation S shall be issued initially in the form of the
Regulation S Temporary Global Security and bearing the Regulation S Temporary
Global Security Legend, which shall be deposited on behalf of the purchasers of
the Securities represented thereby with the Trustee, at its Houston, Texas
office, as custodian for the Depositary, and registered in the name of the
Depositary or the nominee of the Depositary for the accounts of designated
agents holding on behalf of Euroclear or Clearstream, duly executed by the
Company and authenticated by the Trustee as hereinafter provided. The
Distribution Compliance Period shall be terminated upon the receipt by the
Trustee of (i) a written certificate from the Depositary, together with copies
of certificates from Euroclear and Clearstream certifying that they have
received certification of non-U.S. beneficial ownership of 100% of the aggregate
principal amount of the Regulation S Temporary Global Security (except to the
extent of any beneficial owners thereof who acquired an interest therein during
the Distribution Compliance Period pursuant to another exemption from
registration under the Securities Act and who will take delivery of a beneficial
ownership interest in a 144A Global Security bearing a Private Placement Legend,
all as contemplated by Section 2.06(g)(i)), and (ii) an Officers' Certificate
from the Company. Following the termination of the Distribution Compliance
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. Simultaneously with the
authentication of Regulation S Permanent Global Securities, the Trustee shall
cancel the Regulation S Temporary Global Security. The aggregate principal
amount of the Regulation S Temporary Global Security and the Regulation S
Permanent Global Securities may from time to time be increased or decreased by
adjustments made on the records of the

<PAGE>
                                      -14-

Trustee and the Depositary or its nominee, as the case may be, in connection
with transfers of interest as hereinafter provided.

                  (d) Euroclear and Clearstream Procedures Applicable. The
provisions of the "Operating Procedures of the Euroclear System" and "Terms and
Conditions Governing Use of Euroclear" and the "General Terms and Conditions of
Clearstream" and "Customer Handbook" of Cedel Bank (as adopted by Clearstream)
and any successor, alternative or additional procedures from time to time
adopted by Euroclear or Clearstream shall be applicable to transfers of
beneficial interests in the Regulation S Temporary Global Security and the
Regulation S Permanent Global Securities that are held by Participants through
Euroclear or Clearstream.

                  (e) Certificated Securities. Except as provided in this
Section 2.01 or Section 2.06, owners of beneficial interests in Global
Securities will not be entitled to receive physical delivery of Definitive
Securities.

SECTION 2.02. Execution and Authentication.

                  One Officer of the Company shall sign the Securities on behalf
of the Company by manual or facsimile signature. The Company's seal may be (but
shall not be required to be) impressed, affixed, imprinted or reproduced on the
Securities and may be in facsimile form.

                  If an Officer of the Company whose signature is on this
Indenture or a Security no longer holds that office at the time the Trustee
authenticates such Security or at any time thereafter, the Security shall be
valid nevertheless.

                  A Security shall not be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose until authenticated by the
manual signature of an authorized signatory of the Trustee, which signature
shall be conclusive evidence that the Security has been authenticated under this
Indenture.

                  The Trustee shall authenticate (i) for original issue on the
Issue Date each of (A) the Series A 10-Year Securities in the aggregate
principal amount of $1,750,000,000 and (B) the Series A 30-Year Securities in
the aggregate principal amount of $1,250,000,000 (collectively, the "Original
Securities"), (ii) the Series B Securities for original issue, pursuant to an
Exchange Offer or Private Exchange, for a like principal amount of Series A
Securities and (iii) any amount of additional Securities specified by the
Company, in each case, upon a written order of the Company signed by one Officer
of the Company; provided, however, that no additional Securities may be issued
or guaranteed if a Default or Event of Default shall have occurred and be
continuing with respect to any series of the Securities. Such order shall
specify (a) the amount of the Securities of each series to be authenticated and
the date of

<PAGE>
                                      -15-

original issue thereof, and (b) whether the Securities are Series A Securities
or Series B Securities. The aggregate principal amount of Securities of any
series outstanding at any time may not exceed the aggregate principal amount of
Securities of such series authorized for issuance by the Company pursuant to one
or more written orders of the Company, except as provided in Section 2.07.
Subject to the foregoing, the aggregate principal amount of Securities of any
series that may be issued under this Indenture shall not be limited.

                  The Trustee may appoint an authenticating agent acceptable to
the Company to authenticate Securities. Unless limited by the terms of such
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with the Company, the Guarantor or any of their
respective Affiliates.

                  The 10-Year Securities and the 30-Year Securities shall each
be a single series for all purposes of this Indenture, including, without
limitation, waivers, amendments, redemptions and offers to purchase.

SECTION 2.03. Registrar and Paying Agent.

                  The Company shall maintain an office or agency where
Securities may be presented for registration of transfer or exchange
("Registrar") and an office or agency where Securities may be presented for
payment ("Paying Agent"). The Registrar shall keep a register of the Securities
and of their transfer and exchange. The Company may appoint one or more
co-registrars and one or more additional paying agents. The term "Registrar"
includes any co-registrar and the term "Paying Agent" includes any additional
paying agent.

                  The Company shall enter into an appropriate agency agreement
with any Registrar or Paying Agent not a party to this Indenture. The agreement
shall implement the provisions of this Indenture that relate to such Agent. The
Company shall notify the Trustee of the name and address of any Agent not a
party to this Indenture. The Company may change any Paying Agent or Registrar
without notice to any Holder. If the Company fails to appoint or maintain
another entity as Registrar or Paying Agent, the Trustee shall act as such. The
Guarantor or any of its Subsidiaries may act as Paying Agent or Registrar.

                  The Company initially appoints the Trustee as Registrar and
Paying Agent.

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

SECTION 2.04. Paying Agent to Hold Money in Trust.

                  The Company shall require each Paying Agent other than the
Trustee to agree in writing that the Paying Agent will hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the
payment of principal of or premium, if any, Liquidated Damages, if any,
Additional Amounts, if any, or interest on the Securities, whether such money
shall have been paid to it by the Company or the Guarantor, and will notify the
Trustee of any default by the Company or the Guarantor in making any such
payment. While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee and to account for any funds
disbursed. The Company at any time may require a Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed. Upon payment
over to the Trustee and upon accounting for any funds disbursed, the Paying
Agent (if other than the Company or a Subsidiary of the Company) shall have no
further liability for the money. If the Company or a Subsidiary of the Company
acts as Paying Agent, it shall segregate and hold in a separate trust fund for
the benefit of the Holders all money held by it as Paying Agent.

SECTION 2.05. Holder Lists.

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

SECTION 2.06. Transfer and Exchange.

                  (a) Transfer and Exchange of Global Securities. A Global
Security may not be transferred as a whole except by the Depositary to a nominee
of the Depositary, by a nominee of the Depositary to the Depositary or to
another nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global
Securities will be exchanged by the Company for Definitive Securities if (i) the
Trustee receives notice from the Depositary that it is unwilling or unable to
continue to act as Depositary or that it is no longer a clearing agency
registered under the Exchange Act and, in either case, a successor Depositary is
not appointed by the Company within 90 days after the date of such notice from
the Depositary or (ii) the Company in its sole discretion determines that the
Global Securities (in whole but not in part) should be exchanged for Definitive
Securities and delivers a written notice to such effect to the Trustee; provided
that in no event shall the Regulation S Temporary Global Security be exchanged
by the Company for Definitive Securities prior to (x) the expiration of the
Distribution Compliance Period and

<PAGE>
                                      -17-

(y) the receipt by the Registrar of any certificates required pursuant to Rule
903(c)(3)(ii)(B) under the Securities Act. Upon the occurrence of either of the
preceding events in (i) or (ii) above, Definitive Securities shall be issued in
such names as the Depositary shall instruct the Trustee. Global Securities also
may be exchanged or replaced, in whole or in part, as provided in Sections 2.07
and 2.10. Except as provided in this Section 2.06(a) and in Section 2.06(b)(ii)
and Section 2.06(c) for the exchange or transfer of Global Securities for
Definitive Securities, every Security authenticated and delivered in exchange
for, or in lieu of, a Global Security or any portion thereof, pursuant to this
Section 2.06 or Section 2.07 or 2.10, shall be authenticated and delivered in
the form of, and shall be, a Global Security. A Global Security may not be
exchanged for another Security other than as provided in this Section 2.06(a);
however, beneficial interests in a Global Security may be transferred and
exchanged as provided in Section 2.06(b), (c) or (f).

                  (b) Transfer and Exchange of Beneficial Interests in the
Global Securities. The transfer and exchange of beneficial interests in the
Global Securities shall be effected through the Depositary, in accordance with
the provisions of this Indenture and the Applicable Procedures. Beneficial
interests in the Restricted Global Securities shall be subject to restrictions
on transfer comparable to those set forth herein to the extent required by the
Securities Act. Transfers of beneficial interests in the Global Securities also
shall require compliance with either subparagraph (i) or (ii) below, as
applicable, as well as one or more of the other following subparagraphs, as
applicable:

                  (i) Transfer of Beneficial Interests in the Same Global
         Security. Beneficial interests in any Restricted Global Security may be
         transferred to Persons who take delivery thereof in the form of a
         beneficial interest in the same Restricted Global Security in
         accordance with the transfer restrictions set forth in the Private
         Placement Legend; provided, however, that prior to the expiration of
         the Distribution Compliance Period, transfers of beneficial interests
         in the Temporary Regulation S Global Security may not be made to a U.S.
         Person or for the account or benefit of a U.S. Person. Beneficial
         interests in any Unrestricted Global Security may be transferred to
         Persons who take delivery thereof in the form of a beneficial interest
         in an Unrestricted Global Security. No written orders or instructions
         shall be required to be delivered to the Registrar to effect the
         transfers described in this Section 2.06(b)(i).

                  (ii) All Other Transfers and Exchanges of Beneficial Interests
         in Global Securities. In connection with all transfers and exchanges of
         beneficial interests that are not subject to Section 2.06(b)(i) above,
         the transferor of such beneficial interest must deliver to the
         Depositary either (A) (1) a written order from a Participant or an
         Indirect Participant given to the Depositary in accordance with the
         Applicable Procedures directing the Depositary to credit or cause to be
         credited a beneficial interest in another Global Security in an amount
         equal to the beneficial interest to be transferred or

<PAGE>
                                      -18-

         exchanged and (2) instructions given in accordance with the Applicable
         Procedures containing information regarding the Participant account to
         be credited with such increase or (B) (1) a written order from a
         Participant or an Indirect Participant given to the Depositary in
         accordance with the Applicable Procedures directing the Depositary to
         cause to be issued a Definitive Security in an amount equal to the
         beneficial interest to be transferred or exchanged and (2) instructions
         given by the Depositary to the Registrar containing information
         regarding the Person in whose name such Definitive Security shall be
         registered to effect the transfer or exchange referred to in (1) above;
         provided that in no event shall Definitive Securities be issued upon
         the transfer or exchange of beneficial interests in the Regulation S
         Temporary Global Security prior to (x) the expiration of the
         Distribution Compliance Period and (y) the receipt by the Registrar of
         any certificates required pursuant to Rule 903 under the Securities
         Act. Upon consummation of an Exchange Offer by the Company in
         accordance with Section 2.06(f), the requirements of this Section
         2.06(b)(ii) shall be deemed to have been satisfied upon receipt by the
         Registrar of the instructions contained in the Letter of Transmittal
         delivered by the Holder of such beneficial interests in the Restricted
         Global Securities. Upon satisfaction of all of the requirements for
         transfer or exchange of beneficial interests in Global Securities
         contained in this Indenture and the Securities or otherwise applicable
         under the Securities Act, the Trustee shall adjust the principal amount
         of the relevant Global Security(s) pursuant to Section 2.06(h).

                  (iii) Transfer of Beneficial Interests to Another Restricted
         Global Security. A beneficial interest in any Restricted Global
         Security may be transferred to a Person who takes delivery thereof in
         the form of a beneficial interest in another Restricted Global Security
         if the transfer complies with the requirements of Section 2.06(b)(ii)
         above and the Registrar receives the following:

                           (A) if the transferee will take delivery in the form
                  of a beneficial interest in the 144A Global Security, then the
                  transferor must deliver a certificate in the form of Exhibit C
                  hereto, including the certifications in item (1) thereof; and

                           (B) if the transferee will take delivery in the form
                  of a beneficial interest in the Regulation S Temporary Global
                  Security or the Regulation S Permanent Global Security, then
                  the transferor must deliver a certificate in the form of
                  Exhibit C hereto, including the certifications in item (2)
                  thereof.

                  (iv) Transfer and Exchange of Beneficial Interests in a
         Restricted Global Security for Beneficial Interests in the Unrestricted
         Global Security. A beneficial interest in any Restricted Global
         Security may be exchanged by any holder thereof for a beneficial
         interest in an Unrestricted Global Security or transferred to a Person
         who

<PAGE>
                                      -19-

         takes delivery thereof in the form of a beneficial interest in an
         Unrestricted Global Security if the exchange or transfer complies with
         the requirements of Section 2.06(b)(ii) above and:

                           (A) such exchange or transfer is effected pursuant to
                  the Exchange Offer in accordance with the Registration Rights
                  Agreement and the holder of such beneficial interest, in the
                  case of an exchange, or the transferee, in the case of a
                  transfer, certifies in the applicable Letter of Transmittal or
                  via the Depositary's book-entry system that it is not (1) a
                  broker-dealer, (2) a Person participating in the distribution
                  of the Series B Securities or (3) a Person who is an affiliate
                  (as defined in Rule 144) of the Company;

                           (B) such transfer is effected pursuant to the Shelf
                  Registration in accordance with the Registration Rights
                  Agreement;

                           (C) such transfer is effected by a Participating
                  Broker-Dealer pursuant to the Exchange Offer Registration
                  Statement in accordance with the Registration Rights
                  Agreement; or

                           (D) the Registrar receives the following:

                                    (1) if the holder of such beneficial
                           interest in a Restricted Global Security proposes to
                           exchange such beneficial interest for a beneficial
                           interest in an Unrestricted Global Security, a
                           certificate from such holder in the form of Exhibit
                           D, including the certifications in item (1)(a)
                           thereof; or

                                    (2) if the holder of such beneficial
                           interest in a Restricted Global Security proposes to
                           transfer such beneficial interest to a Person who
                           shall take delivery thereof in the form of a
                           beneficial interest in an Unrestricted Global
                           Security, a certificate from such holder in the form
                           of Exhibit C, including the certifications in item
                           (4) thereof;

                  and, in each such case set forth in this subparagraph (D), if
                  the Registrar so requests or if the Applicable Procedures so
                  require, an Opinion of Counsel in form reasonably acceptable
                  to the Registrar to the effect that such exchange or transfer
                  is in compliance with the Securities Act and that the
                  restrictions on transfer contained herein and in the Private
                  Placement Legend are no longer required in order to maintain
                  compliance with the Securities Act.

                  If any such transfer is effected pursuant to subparagraph (B)
         or (D) above at a time when an Unrestricted Global Security has not yet
         been issued, the Company shall

<PAGE>
                                      -20-

         issue and, upon receipt of a written authentication order in accordance
         with Section 2.02, the Trustee shall authenticate one or more
         Unrestricted Global Securities in an aggregate principal amount equal
         to the aggregate principal amount of beneficial interests transferred
         pursuant to subparagraph (B) or (D) above.

                  Beneficial interests in an Unrestricted Global Security cannot
         be exchanged for, or transferred to Persons who take delivery thereof
         in the form of, a beneficial interest in a Restricted Global Security.

                  (c) Transfer or Exchange of Beneficial Interests for
         Definitive Securities.

                  (i) Beneficial Interests in Restricted Global Securities to
         Restricted Definitive Securities. If any holder of a beneficial
         interest in a Restricted Global Security proposes to exchange such
         beneficial interest for a Restricted Definitive Security or to transfer
         such beneficial interest to a Person who takes delivery thereof in the
         form of a Restricted Definitive Security, then, upon receipt by the
         Registrar of the following documentation:

                           (A) if the holder of such beneficial interest in a
                  Restricted Global Security proposes to exchange such
                  beneficial interest for a Restricted Definitive Security, a
                  certificate from such holder in the form of Exhibit D,
                  including the certifications in item (2)(a) thereof;

                  Act, a certificate to the effect set forth in Exhibit C,
                  including the certifications in item (1) thereof;

                           (C) if such beneficial interest is being transferred
                  to a Non-U.S. Person in an offshore transaction in accordance
                  with Rule 903 or Rule 904 under the Securities Act, a
                  certificate to the effect set forth in Exhibit C, including

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

                  (iii) Unrestricted Definitive Securities to Unrestricted
         Definitive Securities. A Holder of Unrestricted Definitive Securities
         may transfer such Securities to a Person who takes delivery thereof in
         the form of an Unrestricted Definitive Security. Upon receipt of a
         request to register such a transfer, the Registrar shall register the

the Trustee shall authenticate (i) one or more Unrestricted Global Securities in
an aggregate principal amount equal to the principal amount of the beneficial
interests in the Restricted Global Securities tendered for acceptance by Persons

amount of the applicable Restricted Global Securities to be reduced accordingly,
and the Company shall execute and the Trustee shall authenticate and deliver to
the Persons designated by the Holders of Definitive Securities so accepted
Definitive Securities in the appropriate principal amounts.

                  thereof) shall bear the legend in substantially the following
                  form:

              OF COUNSEL, CERTIFICATIONS AND/OR OTHER INFORMATION THAT IT
              REASONABLY REQUIRES TO CONFIRM THAT SUCH PROPOSED TRANSFER IS
              BEING MADE PURSUANT TO AN EXEMPTION FROM THE REGISTRATION
              REQUIREMENTS OF THE SECURITIES ACT.

                  AS USED IN THIS SECURITY, THE TERMS "OFFSHORE TRANSACTION,"
         "U.S. PERSON" AND "UNITED STATES" HAVE THE MEANINGS GIVEN TO THEM
         WITHIN REGULATION S.

                           (B) Notwithstanding the foregoing, any Global

                  DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A

                  PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE
                  REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
                  TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY

                  EXCHANGE FOR CERTIFICATED SECURITIES, ARE AS SPECIFIED IN THE

                  SECURITY SHALL BE ENTITLED TO RECEIVE PAYMENT OF INTEREST
                  HEREON.

                  (iv) 144A Security Legend. Any Series A Security that is a
         144A Global Security or a Definitive Security sold to QIBs pursuant to
         Rule 144A shall bear a legend in substantially the following form:

                  EACH PURCHASER OF THE SECURITY IS HEREBY NOTIFIED THAT THE
                  SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM
                  THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY
                  RULE 144A THEREUNDER.

                  (h) Cancellation and/or Adjustment of Global Securities. At
such time as all beneficial interests in a particular Global Security have been
exchanged for Definitive Securities or a particular Global Security has been
redeemed, repurchased or canceled in whole and not in part, each such Global
Security shall be returned to or retained and canceled by the Trustee in
accordance with Section 2.11. At any time prior to such cancellation, if any
beneficial interest in a Global Security is exchanged for or transferred to a
Person who will take delivery thereof in the form of a beneficial interest in
another Global Security or for Definitive Securities, the principal amount of
Securities represented by such Global Security shall be reduced accordingly and
an endorsement shall be made on such Global Security by the Trustee or by the

<PAGE>
                                      -31-

beneficial interest is being exchanged for or transferred to a Person who will

Security, such other Global Security shall be increased accordingly and an
endorsement shall be made on such Global Security by the Trustee or by the
Depositary at the direction of the Trustee to reflect such increase.

                  (i) General Provisions Relating to Transfers and Exchanges.

                  (i) To permit registrations of transfers and exchanges, the
         Company shall execute and the Trustee shall authenticate Global
         Securities and Definitive Securities upon the Company's order or at the
         Registrar's request.

                  (ii) No service charge shall be made to a holder of a
         beneficial interest in a Global Security or to a Holder of a Definitive
         Security for any registration of transfer or exchange, but the Company
         may require payment of a sum sufficient to cover any transfer tax or
         similar governmental charge payable in connection therewith (other than
         any such transfer taxes or similar governmental charge payable upon
         exchange or transfer pursuant to Sections 2.10, 8.05 and 10.06).

                  (iii) The Registrar shall not be required (A) to register the
         transfer of or to exchange any Securities during a period beginning at
         the opening of business 15 days before the day of the mailing of notice
         of redemption under Section 10.03 and ending at the close of business
         on such day, or (B) to register the transfer of or exchange any
         Security selected for redemption in whole or in part, except the
         unredeemed portion of any Security being redeemed in part.

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

                  (v) The Company shall not be required (A) to issue, to
         register the transfer of or to exchange any Securities during a period
         beginning at the opening of business 15 days before the day of the
         mailing of notice of redemption under Section 10.03 and ending at the
         close of business on such day, or (B) to register the transfer of or to
         exchange any Security so selected for redemption in whole or in part,
         except the unredeemed portion of any Security being redeemed in part.

         Definitive Securities in accordance with the provisions of Section
         2.02.

<PAGE>
                                      -32-

                  (vii) All certifications, certificates and Opinions of Counsel
         required to be submitted to the Registrar pursuant to this Section 2.06
         to effect a registration of transfer or exchange may be submitted by
         facsimile.

SECTION 2.07. Replacement Securities.

                  If any mutilated Security is surrendered to the Trustee, or
the Company and the Guarantor and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Security, the Company
shall issue and the Trustee shall authenticate a replacement Security, in the
same form as that of the destroyed, lost or stolen Security but only if the
Trustee's requirements are met. If required by the Trustee, the Company or the
Guarantor, such Holder must furnish an indemnity bond that is sufficient in the
judgment of the Trustee, the Company and the Guarantor to protect the Company,
the Guarantor, the Trustee, any Agent or any authenticating agent from any loss
which any of them may suffer if a Security is replaced. The Company, the Trustee
and the Guarantor may charge for their expenses in replacing a Security. If,
after the delivery of such replacement Security, a bona fide purchaser of the
original Security in lieu of which such replacement Security was issued presents
for payment or registration such original Security, the Trustee shall be
entitled to recover such replacement Security from the Person to whom it was
delivered or any Person taking therefrom, except a bona fide purchaser, and
shall be entitled to recover upon the security or indemnity provided therefor to
the extent of any loss, damage, cost or expense incurred by the Trustee, the
Company or the Guarantor in connection therewith.

                  Every replacement Security is a contractual obligation of the
Company.

SECTION 2.08. Outstanding Securities.

                  The Securities outstanding at any time are all the Securities
authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest in a Global Security
effected by the Trustee hereunder and those described in this Section 2.08 as
not outstanding; provided, however, that in determining whether the Holders of
the requisite principal amount of outstanding Securities are present at a
meeting of Holders of Securities for quorum purposes or have consented to or
voted in favor of any request, demand, authorization, direction, notice,
consent, waiver, amendment or modification hereunder, Securities held for the
account of the Company, the Guarantor or any of their Affiliates shall be
disregarded and deemed not to be outstanding, except that in determining whether
the Trustee shall be protected in making such a determination or relying upon
any such quorum, consent or vote, only Securities which a Responsible Officer of
the Trustee actually knows to be so owned shall be so disregarded.

<PAGE>
                                      -33-

                  If a Security is replaced pursuant to Section 2.07, it ceases
to be outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

                  If the principal amount of any Security is considered paid
under Section 3.01, it ceases to be outstanding and interest on it ceases to
accrue.

                  A Security does not cease to be outstanding because the
Company, the Guarantor or any of their respective Affiliates holds the Security.

SECTION 2.09. Treasury Securities.

                  In determining whether the Holders of the required principal
amount of Securities of any series have concurred in any direction, waiver or
consent, Securities owned by the Company, the Guarantor or any of their
respective Affiliates shall be disregarded, except that for the purpose of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Securities which the Trustee actually knows
are so owned shall be so disregarded.

SECTION 2.10. Temporary Securities.

                  Until definitive Securities are ready for delivery, the
Company may prepare and the Trustee shall authenticate temporary Securities.
Temporary Securities shall be substantially in the form of definitive
Securities, but may have variations that the Company considers appropriate for
temporary Securities. Without unreasonable delay, the Company shall prepare and
the Trustee shall authenticate definitive Securities in exchange for temporary
Securities. Until so exchanged, temporary Securities shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities.

SECTION 2.11. Cancellation.

                  The Company or the Guarantor at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee shall cancel all Securities
surrendered for registration of transfer, exchange, payment, replacement or
cancellation. All canceled Securities held by the Trustee shall be disposed of
in accordance with the usual disposal procedures of the Trustee. The Company may
not issue new Securities to replace Securities that have been paid or that have
been delivered to the Trustee for cancellation.

                                      -34-

SECTION 2.12. Defaulted Interest.

                  If the Company defaults in a payment of interest on the
Securities, it shall pay the defaulted interest in any lawful manner plus, to
the extent lawful, interest on the defaulted interest, in each case at the rate
provided in the Securities and in the manner provided in Section 3.01. The
Company may pay the defaulted interest to the Persons who are Holders on a
subsequent special record date. At least 15 days before any special record date,
the Company (or the Trustee, in the name of and at the expense of the Company)
shall mail to Holders a notice that states the special record date, the related
payment date and the amount of such interest to be paid.

SECTION 2.13. Persons Deemed Owners.

                  The Company, the Guarantor, the Trustee, any Agent and any
authenticating agent may treat the Person in whose name any Security is
registered as the owner of such Security for the purpose of receiving payments
of principal of or premium, if any, Liquidated Damages, if any, Additional
Amounts, if any, or interest on such Security and for all other purposes. None
of the Company, the Guarantor, the Trustee, any Agent or any authenticating
agent shall be affected by any notice to the contrary.

SECTION 2.14. CUSIP Numbers.

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

                                   ARTICLE III

                                    COVENANTS

Liquidated Damages, if any, Additional Amounts, if any, and interest on the
Securities on the dates and in the manner provided in the Securities and in this
Indenture. Principal, premium, if any,

<PAGE>
                                      -35-

Liquidated Damages, if any, Additional Amounts, if any, and interest shall be
considered paid on the date due if the Paying Agent, other than the Company or a
Subsidiary of the Company, holds by 11:00 a.m., Eastern time, on that date money
deposited by or on behalf of the Company designated for and sufficient to pay
all principal, premium, if any, Liquidated Damages, if any, Additional Amounts,
if any, and interest then due.

                  To the extent lawful, the Company shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal, premium, if any, Liquidated Damages, if any, Additional
Amounts, if any, and interest (without regard to any applicable grace period) at
a rate equal to the then applicable interest rate on the Securities.

                  Solely for purposes of disclosure pursuant to the Interest Act
(Canada) (and for no other purpose), the annual interest rate applicable to any
series of Securities, for any portion of any period of less than one year will
be the percentage interest rate per annum stipulated in the Securities as to
which the calculation must be made, multiplied by the number of days in the
calendar year in which the applicable interest is paid, divided by 360.

SECTION 3.02. Maintenance of Office or Agency.

                  The Company will maintain, in the Borough of Manhattan, The
City of New York, an office or agency (which may be an office of the Trustee,
the Registrar or the Paying Agent) where Securities may be presented for
registration of transfer or exchange, where Securities may be presented for
payment and where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served. Unless otherwise designated by the
Company by written notice to the Trustee, such office or agency shall be the
principal office of the Trustee in the Borough of Manhattan, The City of New
York at 55 Water Street, Room 234 North, New York, New York 10041. The Company
will give prompt written notice to the Trustee of the location, and any change
in the location, of such office or agency. If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee.

                  The Company may also from time to time designate one or more
other offices or agencies where the Securities may be presented or surrendered
for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in the Borough of Manhattan, The City of New York, 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 of the Trustee
as one such office or agency of the Company in accordance with Section 2.03.

                  (a) The Parent covenants and agrees to file with the Trustee
copies, within 15 days after the Parent is required to file the same with the
SEC, of the annual reports and of the information, documents and other reports
(or copies of such portions of any of the foregoing as the SEC may from time to
time by rules and regulations prescribe) which the Parent may be required to
file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act;
or, if the Parent is not required to file information, documents or reports
pursuant to either of such sections, then to file with the Trustee and the SEC,
in accordance with rules and regulations prescribed from time to time by the
SEC, such of the supplementary and periodic information, documents and reports,
if any, which may be required pursuant to Section 13 of the Exchange Act, in
respect of a security listed and registered on a national securities exchange as
may be prescribed from time to time in such rules and regulations.

                  (b) The Parent covenants and agrees to file with the Trustee
and the SEC, in accordance with the rules and regulations prescribed from time
to time by the SEC, such additional information, documents and reports, if any,
with respect to compliance by the Parent with the conditions and covenants
provided for in this Indenture as may be required from time to time by such
rules and regulations.

                  (c) The Parent covenants and agrees to transmit by mail to all
Holders, as the name and addresses of such Holders appear upon the register kept
by the Registrar, within 30 days after the filing thereof with the Trustee, such
summaries or information, documents and reports required to be filed by the
Parent, if any, pursuant to subsections (a) and (b) of this Section 3.03 as may
be required by rules and regulations prescribed from time to time by the SEC.

                  (d) At any time when neither the Parent nor the Company is
subject to Section 13 or 15(d) of the Exchange Act and the Securities are freely
transferrable under the Securities Act as contemplated by the Registration
Rights Agreement, upon the request of a Holder, the Parent and the Company will
promptly furnish or cause to be furnished the information specified under Rule
144A(d)(4) of the Securities Act to such Holder, or to a prospective purchaser
of a Security designed by such Holder, in order to permit compliance with Rule
144A under the Securities Act.

SECTION 3.04. Compliance Certificate.

                  The Company and the Guarantor shall deliver to the Trustee,
within 120 days after the end of each fiscal year of the Company, a statement
signed by two Officers of the Company (one of whom shall be the Chief Executive
Officer, Chief Financial Officer or Chief Accounting Officer of the Company) and
two Officers of the Guarantor (one of whom shall be the Chief Executive Officer,
Chief Financial Officer or Chief Accounting Officer of the

<PAGE>
                                      -37-

Guarantor), which statement need not constitute an Officers' Certificate,
complying with TIA Section 314(a)(4) and stating that in the course of
performance by the signing Officers of the Company and Officers of the Guarantor
of their duties as such Officers, they would normally obtain knowledge of the
keeping, observing, performing and fulfilling by the Company and the Guarantor,
respectively, of its obligations under this Indenture, and further stating, as
to each such Officer signing such statement, that to the best of his knowledge,
each of the Company and the Guarantor has kept, observed, performed and
fulfilled each and every covenant contained in this Indenture and is not in
default in the performance or observance of any of the terms, provisions and
conditions hereof (or, if a Default or Event of Default shall have occurred,
describing all such Defaults or Events of Default of which such Officer may have
knowledge and what action the Company or the Guarantor, as the case may be, is
taking or proposes to take with respect thereto).

SECTION 3.05. Corporate Existence.

                  Subject to Article IV, each of the Company and the Guarantor
will do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence, under the laws of its respective
jurisdiction of incorporation and formation and all its rights (charter and
statutory) thereunder; provided, however, that neither the Company nor the
Guarantor shall be required to preserve any such right if the Board of Directors
of the Parent shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company or the Parent and that
the loss thereof is not disadvantageous in any material respect to the Holders
of Securities.

SECTION 3.06. Waiver of Stay, Extension or Usury Laws.

                  Each of the Company and the Guarantor covenant (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 or any usury law or other law, which would prohibit or forgive
the Company or the Guarantor from paying all or any portion of the principal of
or premium, if any, Liquidated Damages, if any, Additional Amounts, if any, or
interest on the Securities as contemplated herein, wherever enacted, now or at
any time hereafter in force, or which may affect the covenants or the
performance of this Indenture; and (to the extent that they may lawfully do so)
each of the Company and the Guarantor 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.

SECTION 3.07. Limitation on Liens.

                  The Parent will not itself, nor will the Parent permit any
Restricted Subsidiary to, incur, issue, assume or guarantee any indebtedness for
money borrowed (all such indebtedness for money borrowed being hereinafter in
this Article III called "Debt") secured by a Mortgage on any Principal Property
or on any shares of stock or Indebtedness of any Restricted Subsidiary, without
first effectively providing that the Securities of any series (together with, if
the Parent shall so determine, any other indebtedness of the Guarantor or any
Restricted Subsidiary which is not subordinate in right of payment to the prior
right of payment in full of the Securities of any series) shall be secured
equally and ratably with (or prior to) such secured Debt, for so long as such
secured Debt shall be so secured, unless, after giving effect thereto, the
principal amount of all Debt so secured would not exceed 10% of Consolidated Net
Tangible Assets; provided, however, that this Section 3.07 shall not apply to,
and there shall be excluded from secured Debt in any computation under this
Section 3.07, Debt secured by:

                  (1) Mortgages existing at the date of this Indenture;

                  (2) Mortgages on property of, or on any shares of stock or
         Indebtedness of, any entity existing at the time such entity is merged
         into or consolidated with the Company or the Guarantor or becomes a
         Restricted Subsidiary;

                  (3) Mortgages in favor of the Guarantor or any Restricted
         Subsidiary;

                  (4) Mortgages on property, shares of stock or Indebtedness
         existing at the time of acquisition thereof (including acquisitions
         through merger, consolidation or other reorganization) or to secure the
         payment of all or any part of the purchase price thereof or
         construction thereon or to secure any Debt incurred prior to, at the
         time of, or within one year after the later of the acquisition, the
         completion of construction or the commencement of full operation of
         such property or within one year after the acquisition of such shares
         or Indebtedness for the purpose of financing all or any part of the
         purchase price thereof or construction thereon, it being understood
         that if a commitment for such financing is obtained prior to or within
         such one-year period, the applicable Mortgage shall be deemed to be
         included in this clause (4) whether or not such Mortgage is created
         within such one-year period;

                  (5) Mortgages in favor of the United States of America, any
         State thereof, Canada, or any province thereof, or any department,

                  (6) Mortgages on minerals or geothermal resources in place, or
         on related leasehold or other property interests, that are incurred to
         finance development, production or acquisition costs (including, but
         not limited to, Mortgages securing advance sale obligations);

                  (7) Mortgages on equipment used or usable for drilling,
         servicing or operating oil, gas, coal or other mineral properties or
         geothermal properties;

                  (8) Mortgages required by any contract or statute in order to
         permit the Parent or any of its Subsidiaries to perform any contract or
         subcontract made with or at the request of, the United States of
         America, any State thereof, Canada, any province thereof, or in favor
         of any other country or any political subdivision thereof or any
         department, agency or instrumentality of the United States, any State
         thereof, Canada, any province thereof or any other country or political
         subdivision thereof;

                  (9) any Mortgage resulting from the deposit of moneys or

         the Guarantor or any Restricted Subsidiary or secured Debt of the
         Guarantor or any Restricted Subsidiary the net proceeds of which are
         used, substantially concurrent with the funding thereof, and taking
         into consideration, among other things, required notices to be given to
         the holders of the outstanding securities in connection with the
         refunding, refinancing or repurchase thereof, and the required
         corresponding durations thereof, to refund, refinance or repurchase all
         of the outstanding securities, including the amount of all accrued
         interest thereon and reasonable fees and expenses and premiums, if any,
         incurred by the Guarantor or any Restricted Subsidiary in connection
         therewith; and

                  (10) any extension, renewal or replacement (or successive
         extensions, renewals or replacements) of any Mortgage referred to in
         the foregoing clauses (1) to (9) of this Section 3.07, inclusive;
         provided, however, that such extension, renewal or replacement Mortgage
         shall be limited to all or a part of the same property (including any
         improvements on such property), shares of stock or Indebtedness that
         secured the Mortgage so extended, renewed or replaced.

                  The following transactions shall not be deemed to create Debt
secured by a Mortgage;

                  (i) the sale or other transfer of oil, gas, coal or other
         minerals in place for a period of time until, or in an amount such
         that, the transferee will realize therefrom a specified amount of money
         (however determined) or a specified amount of oil, gas, coal or other
         minerals, or the sale or other transfer of any other interest in
         property of the character commonly referred to as an oil, gas, coal or
         other mineral payment or a production payment, and including in any
         case, overriding royalty interests, net profit

<PAGE>
                                      -40-

         interests, reversionary interests and carried interests and other
         similar burdens on production; and

                  (ii) the sale or other transfer by the Guarantor or a
         Restricted Subsidiary of properties to a partnership, joint venture or
         other entity whereby the Guarantor or such Restricted Subsidiary would
         retain partial ownership of such properties.

SECTION 3.08. Payment of Additional Amounts.

                  Unless otherwise required by Canadian law, neither the Company
nor the Guarantor will deduct or withhold from payments made with respect to the
Securities and the Guarantees on account of any present or future Taxes. In the
event that either the Company or the Guarantor is required to withhold or deduct
on account of any Taxes due from any payment made under or with respect to the
Securities or the Guarantees, as the case may be, the Company or the Guarantor,
as the case may be, will pay such additional amounts ("Additional Amounts") as
may be necessary so that the net amount received by each Holder of Securities
will equal the amount that the Holder would have received if the Taxes had not
been required to be withheld or deducted; provided that no Additional Amounts
will be payable with respect to a payment made to a Holder (an "Excluded
Holder") to the extent: (i) that any Taxes would not have been so imposed but
for the existence of any present or former connection between the Holder and
Canada or any provincial or territory therein, other than the mere receipt of
the payment, acquisition, ownership or disposition of such Securities or the
exercise or enforcement of rights under the Securities, the Guarantees or this
Indenture; (ii) of any estate, inheritance, gift, sales, transfer or personal
property Taxes imposed with respect to the Securities, except described below or
as otherwise provided in this Indenture; (iii) that any such Taxes would not
have been imposed but for the presentation of the Securities, where presentation
is required, for payment on a date more than 30 days after the date on which the
payment became due and payable or the date on which payment thereof is duly
provided for, whichever is later, except to the extent that the beneficiary or
Holder thereof would have been entitled to Additional Amounts had the Securities
been presented for payment on any date during such 30-day period; or (iv) that
the Holder would not be liable or subject to such withholding or deduction of
Taxes but for the failure to make a valid declaration of non-residence or other
similar claim for exemption, if: (a) the making of the declaration or claim is
required or imposed by statute, treaty, regulation, ruling or administrative
practice of the relevant taxing authority as a precondition to an exemption
from, or reduction in, the relevant Taxes; and (b) at least 60 days prior to the
first payment with respect to which the Company or the Guarantor shall apply
this clause (iv), the Company or the Guarantor shall have notified all Holders
of the Securities in writing that they shall be required to provide this
declaration or claim. The Company and the Guarantor shall also (i) withhold or
deduct such Taxes as required, (ii) remit the full amount of Taxes deducted or
withheld to the relevant taxing authority in accordance with all applicable
laws; (iii) use reasonable efforts to obtain from each relevant taxing

<PAGE>
                                      -41-

authority imposing the Taxes certified copies of tax receipts evidencing the
payment of any Taxes deducted or withheld; and (iv) upon request, make available
to the Holders of the Securities, within 60 days after the date the payment of
any Taxes deducted or withheld is due pursuant to applicable law, certified
copies of tax receipts evidencing such payment by the Company or the Guarantor
and, notwithstanding the Company's or the Guarantor's efforts to obtain the
receipts, if the same are not obtainable, other evidence of such payments.

                  In addition, the Company or the Guarantor will pay any stamp,
issue, registration, documentary or other similar taxes and duties, including
interest, penalties and additional amounts with respect thereto, payable in
Canada or the United States, or any political subdivision or taxing authority of
or in the foregoing with respect to the creation, issue, offering, enforcement,
redemption or retirement of the Securities or Guarantees.

                  At least 30 days prior to each date on which any payment under
or with respect to the Securities is due and payable, if the Company becomes
obligated to pay Additional Amounts with respect to such payment, the Company
(or in respect of the Guarantees, the Guarantor) shall deliver to the Trustee an
Officers' Certificate stating the fact that such Additional Amounts will be
payable, and the amounts so payable and will set forth such other information as
is necessary to enable the Trustee to pay such Additional Amounts to the Holders
on the payment date. Whenever in this Indenture there is mentioned, in any
context, the payment of principal of and premium, if any, Liquidated Damages, if
any, Additional Amounts, if any, or interest (including defaulted interest) or
any other amount payable on or with respect to any of the Securities, such
mention shall be deemed to include mention of the payment of Additional Amounts
provided for in this Section 3.08 to the extent that, in such context,
Additional Amounts are, were or would be payable in respect thereof pursuant to
the provisions of this Section 3.08 and express mention of the payment of
Additional Amounts in those provisions hereof shall not be construed as
excluding Additional Amounts in those provisions hereof where such express
mention is not made (if applicable).

                  The obligations of the Company and the Guarantor under this
Section 3.08 shall survive the termination of this Indenture and the payment of
all amounts under or with respect to this Indenture and the Securities.

         such supplemental indenture comply with this Article IV and that all
         conditions precedent herein provided for relating to such transaction

Guarantor shall not consolidate with or merge into any other Person or convey,
transfer or lease its properties and assets substantially as an entirety to any
Person unless:

                  (1) (A) the entity formed by such consolidation or into which
         the Guarantor is merged or the Person which acquires by conveyance or
         transfer, or which leases, the properties and assets of the Guarantor
         substantially as an entirety shall be an entity organized and existing
         under the laws of the United States of America, any State thereof or
         the District of Columbia and shall expressly assume, by an indenture
         supplemental hereto, executed and delivered to the Trustee, in form
         satisfactory to the Trustee, the due and punctual payment of all
         obligations in respect of the Guarantees

         and the performance of every covenant of this Indenture on the part of
         the Guarantor to be performed or observed;

Guarantor with, or merger of the Company or the Guarantor into, any other
Person, or any conveyance, transfer or lease of the properties and assets of the
Company or the Guarantor substantially as an entirety in accordance with Section
4.01, the successor Person formed by such consolidation or amalgamation or into
which the Company or the Guarantor is merged or to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company or the Guarantor, as the case may

         the continuance of any such decree or order for relief or any such

<PAGE>
                                      -46-

                  (7) the Guarantees in respect of Securities of that series
         cease to be in full force and effect or become unenforceable or invalid
         or are declared null and void (other than in accordance with the terms
         of such Guarantees) or the Guarantor denies or disaffirms its
         obligations under such Guarantees; or

                  (8) any Mitchell Restructuring Event is consummated as
         contemplated in Section 11.18 and, thereafter, Devon HoldCo fails to
         become a "Guarantor" hereunder in accordance with Section 11.18.

provided, however, that the occurrence of any of the events described in the
foregoing clause (3) shall not constitute an Event of Default if such occurrence
is the result of changes in GAAP at the date as of which this Indenture is
executed and a certificate to such effect is delivered to the Trustee by the
Parent's independent public accountants.

                  The Trustee shall not be deemed to know of a Default or Event
of Default unless a Responsible Officer at the Corporate Trust Office of the
Trustee has actual knowledge of such Default or Event of Default or the Trustee
receives written notice at the Corporate Trust Office of the Trustee of such
Default or Event of Default with specific reference to such Default.

                  When a Default is cured, or when an Event of Default is deemed
cured pursuant to Section 5.04, such Default, or Event of Default, as the case
may be, ceases.

SECTION 5.02. Acceleration.

                  If an Event of Default (other than an Event of Default
specified in clause (5) or (6) of Section 5.01) with respect to any series of
Securities occurs and is continuing, the Trustee by notice to the Company and
the Guarantor, or by the Holders of at least 25% in aggregate principal amount
of the then outstanding Securities of such series by written notice to the
Company, the Guarantor and the Trustee, may declare the principal of and
Liquidated Damages, if any, Additional Amounts, if any, and interest on all then
outstanding Securities of such series to be due and payable immediately. Upon
any such declaration the amounts due and payable on the Securities of such
series, as determined in accordance with the next succeeding paragraph, shall be
due and payable immediately. If an Event of Default specified in clause (5) or
(6) of Section 5.01 with respect to the Company or the Guarantor occurs, the
principal of Liquidated Damages, if any, Additional Amounts, if any, and
interest on all Securities then outstanding shall ipso facto become and be
immediately due and payable without any declaration, notice or other act on the
part of the Trustee or any Holder.

                  At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgment for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article V provided, the Holders of a majority in

<PAGE>
                                      -47-

principal amount of the outstanding Securities of that series, by written notice
to the Company, the Guarantor and the Trustee, may rescind and annul such
declaration and its consequences if:

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

                           (A) the principal of and premium, if any, on any
                  Securities of that series which have become due otherwise than
                  by such declaration of acceleration and Liquidated Damages, if
                  any, and Additional Amounts, if any, and any interest thereon
                  at the rate or rates prescribed therefor in such Securities or
                  in this Indenture,

                           (B) all overdue interest, Liquidated Damages, if any,
                  and Additional Amounts, if any, on all Securities of that
                  series,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest and overdue Liquidated
                  Damages, if any, and overdue Additional Amounts, if any, at
                  the rate or rates prescribed therefor in such Securities or in
                  this Indenture, and

                           (D) 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 with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 5.04.

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

                  If the maturity of the Securities of any series is accelerated
pursuant to this Section 5.02, 100% of the principal amount thereof shall become
due and payable plus Liquidated Damages, if any, Additional Amounts, if any, and
interest to the date of payment.

SECTION 5.03. Other Remedies.

                  If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy to collect the payment of principal of and
Liquidated Damages, if any,

<PAGE>
                                      -48-

Additional Amounts, if any, and interest on the Securities or to enforce the
performance of any provision of the Securities, the Guarantees, or this
Indenture.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Holder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 5.04. Waiver of Existing Defaults.

                  Subject to Sections 5.07 and 8.02, the Holders of a majority
in principal amount of the Securities of any series then outstanding by notice
to the Trustee may waive an existing Default or Event of Default and its
consequences (including waivers obtained in connection with a tender offer or
exchange offer for the Securities of such series or a solicitation of consents
in respect of the Securities of such series, provided that in each case such
offer or solicitation is made to all Holders of the Securities of such series
then outstanding on equal terms), except (1) a continuing Default or Event of
Default in the payment of the principal of or premium, if any, Liquidated
Damages, if any, Additional Amounts, if any, or interest on the Securities of
any series or (2) a continuing Default in respect of a provision that under
Section 8.02 cannot be amended without the consent of each Holder affected. Upon
any such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

SECTION 5.05. Control by Majority.

                  The Holders of a majority in principal amount of the
Securities of any series then outstanding may 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 it hereunder with respect to such
series. The Trustee, however, may refuse to follow any direction that conflicts
with applicable law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders, or that may involve the Trustee in
personal liability; provided, however, that the Trustee may take any other
action deemed proper by the Trustee that is not inconsistent with such
direction. Prior to taking any action hereunder, the Trustee shall be entitled
to receive reasonable indemnification satisfactory to it against all losses and
expenses caused by taking or not taking such action subject to the Trustee's
duty to act with the required standard of care during a default.

                                      -49-

SECTION 5.06. Limitations on Suits.

                  Subject to Section 5.07, a Holder may pursue a remedy with
respect to this Indenture (including the Guarantees) or the Securities of any
series only if:

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

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

                  (3) such Holder or Holders furnish to the Trustee reasonable
         indemnity satisfactory to the Trustee against any loss, liability or
         expense;

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

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

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

SECTION 5.07. Rights of Holders to Receive Payment.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder of a Security to receive payment of principal of and
premium, if any, Liquidated Damages, if any, Additional Amounts, if any, and
interest on the Security, on or after the respective due dates expressed in the
Security, or to bring suit against the Company and/or the Guarantor for the
enforcement of any such payment on or after such respective dates, is absolute
and unconditional and shall not be impaired or affected without the consent of
such Holder.

SECTION 5.08. Collection Suit by Trustee.

                  If an Event of Default specified in clause (1) or (2) of
Section 5.01 occurs and is continuing, the Trustee is authorized to recover
judgment in its own name and as trustee of an express trust against the Company
and the Guarantor (i) for the amount of principal of and premium, if any,
Liquidated Damages, if any, Additional Amounts, if any, and interest remaining
unpaid on any series of Securities and (ii) interest on overdue principal,
premium, if any, Liquidated Damages, if any, Additional Amounts, if any, and, to
the extent lawful, interest on overdue interest, and such further amount as
shall be sufficient to cover the costs and

<PAGE>
                                      -50-

expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

SECTION 5.09. Trustee May File Proofs of Claim.

                  The Trustee is authorized to file such proofs of claim and
other papers or documents and to take such actions, including participating as a
member, voting or otherwise, of any committee of creditors, as may be necessary
or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Company and the Guarantor or their respective
creditors or properties and shall be entitled and empowered to collect, receive
and distribute any money or other property payable or deliverable on any such
claims and any Custodian in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee, and in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due to it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 6.07. To the extent that the
payment of any such compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07 out of the estate in any such proceeding, shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out
of, any and all distributions, dividends, money, securities and other properties
which the Holders of the Securities of any series may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities of any series 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 5.10. Priorities.

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

                  First: to the Trustee for amounts due under Section 6.07;

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

<PAGE>
                                      -51-

                  Third: to the Company and the Guarantor.

                  The Trustee, upon prior written notice to the Company and the
Guarantor, may fix a record date and payment date for any payment to Holders
pursuant to this Article V.

SECTION 5.11. Undertaking for Costs.

                  In any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as a trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 5.11 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 5.07, or a suit by a Holder or Holders of more than
10% in principal amount of the Securities of any series then outstanding.

                                   ARTICLE VI

                                     TRUSTEE

SECTION 6.01. Duties of Trustee.

                  (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in such exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

                  (b) Except during the continuance of an Event of Default:

                  (1) the Trustee need perform only those duties that are
         specifically set forth in this Indenture and no others, and no implied
         covenants or obligations shall be read into this Indenture against the
         Trustee; and

                  (2) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall examine such certificates
         and opinions to determine whether or not, on their face, they appear to
         conform to the requirements of this Indenture.

<PAGE>
                                      -52-

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

                  (1) this paragraph does not limit the effect of paragraph (b)
         of this Section 6.01;

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

                  (3) the Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction
         received by it pursuant to Section 5.05.

                  (d) Whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section 6.01.

                  (e) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or incur any liability. The Trustee may refuse
to perform any duty or exercise any right or power unless it receives indemnity
satisfactory to it against any loss, liability or expense.

                  (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law. All money received by the Trustee shall,
until applied as herein provided, be held in trust for the payment of the
principal of and premium, if any, Liquidated Damages, if any, Additional
Amounts, if any, and interest on the Securities.

SECTION 6.02. Rights of Trustee.

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

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

<PAGE>
                                      -53-

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

                  (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers conferred upon it by this Indenture.

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

                  (f) The Trustee is not required to give any bond or surety
with respect to the performance of its duties or the exercise of its powers
under this Indenture.

                  (g) In the event the Trustee receives inconsistent or
conflicting requests and indemnity from two or more groups of Holders of
Securities of a series, each representing less than a majority in aggregate
principal amount of the Securities outstanding of such series, pursuant to the
provisions of this Indenture, the Trustee may determine what action, if any,
shall be taken.

                  (h) The Trustee's immunities and protections from liability
and its right to indemnification in connection with the performance of its
duties under this Indenture shall extend and be enforceable by the Trustee in
each of its capacities hereunder and shall extend to the Trustee's officers,
directors, agents, attorneys and employees. Such immunities and protections and
right to indemnity, together with the Trustee's right to compensation, shall
survive the Trustee's resignation or removal, the discharge of this Indenture
and final payment of the Securities.

                  (i) The permissive right of the Trustee to take the actions
permitted by this Indenture shall not be construed as an obligation or duty to
do so.

                  (j) Except for information provided by the Trustee concerning
the Trustee, the Trustee shall have no responsibility for any information in the
Offering Memorandum or other disclosure material distributed with respect to the
Securities, and the Trustee shall have no responsibility for compliance with any
U.S. or Canadian Federal or State or provincial securities laws in connection
with the Securities.

                  (k) The Trustee may request that the Company or the Guarantor,
as the case may be, deliver an Officers' Certificate setting forth the names of
individuals and/or titles of officers authorized at such time to take specified
actions pursuant to this Indenture, which Officers' Certificate may be signed by
any person authorized to sign an Officers' Certificate,

<PAGE>
                                      -54-

including any person specified as so authorized in any such certificate
previously delivered and not superseded.

SECTION 6.03. Individual Rights of Trustee.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Securities and may otherwise deal with the Company, the
Parent or any of their Affiliates with the same rights it would have if it were
not the Trustee. Any Agent may do the same with like rights. However, the
Trustee is subject to Sections 6.10 and 6.11.

SECTION 6.04. Trustee's Disclaimer.

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

SECTION 6.05. Notice of Defaults.

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

SECTION 6.06. Reports by Trustee to Holders.

                  Within 60 days after May 1 of each year, beginning with May 1,
2002, the Trustee shall mail to Holders a brief report dated as of May 1 of such
year that complies with TIA Section 313(a); provided, however, that if no event
described in TIA Section 313(a) has occurred within the 12 months preceding the
reporting date, no report need be transmitted. The Trustee also shall comply
with TIA Section 313(b). The Trustee shall also transmit by mail all reports as
required by TIA Sections 313(c) and 313(d).

                  A copy of each report at the time of its mailing to Holders
shall be filed with the SEC and each securities exchange, if any, on which the
Securities are listed. The Company shall notify the Trustee if and when the
Securities are listed on any securities exchange.

SECTION 6.07. Compensation and Indemnity.

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

                  The Company and the Guarantor jointly and severally agree to
indemnify the Trustee or any predecessor Trustee and their agents for and to
hold them harmless against any and all loss, liability, damage, claim, or
expense (including taxes, other than taxes based upon, measured by or determined
by the income of the Trustee) incurred by it arising out of or in connection
with the acceptance or administration of its duties under this Indenture,
including the costs and expenses of defending itself against any claim (whether
asserted by the Company, the Guarantor, any Holder or any other Person), except
as set forth in the next paragraph. The Trustee shall notify the Company and the
Guarantor promptly of any claim for which it may seek indemnity. The Company
shall defend the claim and the Trustee shall cooperate in the defense. The
Trustee may have separate counsel, and the Company and the Guarantor shall pay
the reasonable fees and expenses of such counsel. The Company need not pay for
any settlement made without its consent.

                  Neither the Company nor the Guarantor shall be obligated to
reimburse any expense or indemnify against any loss or liability incurred by the
Trustee through negligence or bad faith.

                  To secure the payment obligations of the Company and the
Guarantor in this Section 6.07, the Trustee shall have a lien prior to the
Securities on all money or property held or collected by the Trustee, except
that held in trust to pay principal of and premium, if any, Liquidated Damages,
if any, and Additional Amounts, if any, and interest on the Securities. Such
lien shall survive the satisfaction and discharge of this Indenture.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 5.01(5) or (6) occurs, the expenses and
the compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

SECTION 6.08. Replacement of Trustee.

                  A resignation or removal of the Trustee and appointment of a
successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in this Section 6.08.

                  The Trustee may resign and be discharged from the trust hereby
created by so notifying the Company and the Guarantor. The Holders of a majority
in principal amount of the then outstanding Securities may remove the Trustee by
so notifying the Trustee and the Company. The Company may remove the Trustee if:

                  (1) the Trustee fails to comply with Section 6.10;

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

                  (3) a Custodian or public officer takes charge of the Trustee
         or its property; or

                  (4) the Trustee otherwise becomes incapable of acting.

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Company and the Guarantor shall
promptly appoint a successor Trustee. Within one year after the successor
Trustee takes office, the Holders of a majority in principal amount of the
Securities then outstanding may appoint a successor Trustee to replace the
successor Trustee appointed by the Company.

                  If a successor Trustee does not take office within 30 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of at least 10% in principal amount of the Securities
then outstanding may petition any court of competent jurisdiction at the expense
of the Company for the appointment of a successor Trustee.

                  If the Trustee fails to comply with Section 6.10, any Holder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company and the Guarantor.
Thereupon, the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and
duties of the Trustee under this Indenture. The successor Trustee shall mail a
notice of its succession to Holders. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, subject to
the lien provided for in

<PAGE>
                                      -57-

Section 6.07. Notwithstanding replacement of the Trustee pursuant to this
Section 6.08, the obligations of the Company and the Guarantor under Section
6.07 shall continue for the benefit of the retiring Trustee.

SECTION 6.09. Successor Trustee by Merger, etc.

                  Subject to Section 6.10, if the Trustee consolidates, merges
or converts into, or transfers all or substantially all of its corporate trust
business to, another corporation, the successor corporation without any further
act shall be the successor Trustee; provided, however, that in the case of a
transfer of all or substantially all of its corporate trust business to another
corporation, the transferee corporation expressly assumes all of the Trustee's
liabilities hereunder.

                  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; and in case at that time any of the
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor hereunder or
in the name of the successor to the Trustee; and in all such cases such
certificates shall have the full force which it is anywhere in the Securities or
in this Indenture provided that the certificate of the Trustee shall have.

SECTION 6.10. Eligibility; Disqualification.

                  There shall at all times be a Trustee hereunder which shall be
a corporation organized and doing business under the laws of the United States
of America, any State thereof or the District of Columbia and authorized under
such laws to exercise corporate trust power, shall be subject to supervision or
examination by Federal or State (or the District of Columbia) authority and
shall have, or be a Subsidiary of a bank or bank holding company having, a
combined capital and surplus of at least $50 million as set forth in its most
recent published annual report of condition.

                  This Indenture shall always have a Trustee that satisfies the
requirements of TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is
subject to and shall comply with the provisions of TIA Section 310(b) during the
period of time required by this Indenture. Nothing in this Indenture shall
prevent the Trustee from filing with the SEC the application referred to in the
penultimate paragraph of TIA Section 310(b).

SECTION 6.11. Preferential Collection of Claims Against Company.

                  The Trustee is subject to and shall comply with the provisions
of TIA Section 311(a), excluding any creditor relationship listed in TIA Section
311(b). A Trustee who

<PAGE>
                                      -58-

has resigned or been removed shall be subject to TIA Section 311(a) to the
extent indicated therein.

SECTION 7.01. Termination of Company's Obligations.

                  (a) This Indenture shall cease to be of further effect with
respect to Securities of a series (except that the Company's and the Guarantor's
obligations under Section 6.07 and the Trustee's and Paying Agent's obligations
under Section 7.03 shall survive), and the Trustee, on demand of the Company,
shall execute proper instruments acknowledging the satisfaction and discharge of

                  have been delivered to the Trustee for cancellation; or

                           (B) all outstanding Securities of such series not
                  theretofore delivered to the Trustee for cancellation:

                                    (ii) will become due and payable at their
                           Stated Maturity within one year, or

                                    (iii) will be scheduled for redemption by

                  above, has deposited or caused to be deposited with the
                  Trustee as funds (immediately available to the Holders in the
                  case of clause (i)) in trust for such purpose an amount which,
                  together with earnings thereon, will be sufficient to pay and
                  discharge the entire indebtedness on such Securities of such
                  series for principal, premium, if any, Liquidated Damages, if

                  (2) the Company has paid all other sums payable by it
         hereunder with respect to such series; and

                  (3) the Company has delivered to the Trustee an Officers'
         Certificate stating that all conditions precedent to satisfaction and
         discharge of this Indenture with respect to such series have been

                  (b) The Company and the Guarantor may, subject as provided
herein, terminate all of their obligations under this Indenture with respect to
Securities of a series (and the Guarantees thereof) if:

                  (1) the Company has irrevocably deposited or caused to be
         irrevocably deposited with the Trustee as trust funds in trust for the
         purpose of making the following payments dedicated solely to the
         benefit of the Holders (i) cash in an amount, or (ii) U.S. Government
         Obligations or (iii) a combination thereof, sufficient, in the opinion
         of a nationally recognized firm of independent public accountants
         expressed in a written certification thereof delivered to the Trustee,
         to pay, without consideration of the reinvestment of any such amounts
         and after payment of all taxes or other charges or assessments in
         respect thereof payable by the Trustee, the principal of and premium,
         if any, Liquidated Damages, if any, Additional Amounts, if any and
         interest on all Securities of such series on each date that such
         principal, premium, if any, Liquidated Damages, if any, Additional
         Amounts, if any, or interest is due and payable and to pay all other
         sums payable by it hereunder; provided that the Trustee shall have been
         irrevocably instructed to apply such money and/or the proceeds of such
         U.S. Government Obligations to the payment of said principal, premium,
         if any, Liquidated Damages, if any, Additional Amounts, if any, and
         interest with respect to the Securities of such series as the same
         shall become due;

                  (2) the Company has delivered to the Trustee an Officers'
         Certificate stating that all conditions precedent to satisfaction and
         discharge of this Indenture with respect to Securities of such series
         have been complied with, and an Opinion of Counsel to the same effect;

                  (3) no Default or Event of Default shall have occurred and be
         continuing on the date of such deposit or, insofar as clauses (5) and
         (6) of Section 5.01 are concerned, at any time during the period ending
         on the 91st day after the date of such deposit (it being understood
         that this condition shall not be deemed satisfied until the expiration
         of such period);

                  (4) the Company shall have delivered to the Trustee Opinions
         of Counsel from nationally recognized counsel acceptable to the Trustee
         or a tax ruling to the

<PAGE>
                                      -60-

         effect that the Holders of Securities of such series will not recognize
         income, gain or loss for U.S. or Canadian Federal income tax purposes
         as a result of the Company's exercise of its option under this Section
         7.01(b) and will be subject to U.S. or Canadian Federal income tax on
         the same amounts, in the same manner and at the same times as would
         have been the case if such option had not been exercised;

                  (5) such deposit and discharge will not result in a breach or
         violation of, or constitute a default under, any other agreement or
         instrument to which the Company or the Guarantor is a party or by which
         it is bound;

                  (6) such deposit and discharge shall not cause the Trustee to
         have a conflicting interest as defined in TIA Section 310(b); and

                  (7) the Company shall have delivered to the Trustee an Opinion
         of Counsel to the effect that after the passage of 91 days following
         the deposit, the trust funds will not be subject to the effect of any
         applicable bankruptcy, insolvency, reorganization or similar laws
         affecting creditors' rights generally.

                  In such event, this Indenture shall cease to be of further
effect with respect to Securities of such series (except as provided in the next
succeeding paragraph), and the Trustee, on demand of the Company, shall execute
proper instruments acknowledging satisfaction and discharge under this
Indenture.

                  However, the Company's obligations in Sections 2.03, 2.04,
2.05, 2.06, 2.07, 3.01, 3.02, 3.08, 6.08 and 7.01 the Company's and the
Guarantor' obligations in Sections 4.01, 6.07, 7.04 and 9.01 and the Trustee's
and Paying Agent's obligations in Section 7.03 shall survive until the
Securities of such series are no longer outstanding. Thereafter, only the
Company's and the Guarantor's obligations in Section 6.07 and the Trustee's and
Paying Agent's obligations in Section 7.03 shall survive.

                  After such irrevocable deposit made pursuant to this Section
7.01(b) and satisfaction of the other conditions set forth herein, the Trustee,
on demand of the Company, shall execute proper instruments acknowledging
satisfaction and discharge under this Indenture.

                  (c) The Company and the Guarantor may, subject as provided
herein, be released from their respective obligations to comply with, and shall
have no liability in respect of any term, condition or limitation, set forth in
Sections 3.07 and 4.01 with respect to the Securities of any series, and such
omission to comply with Sections 3.07 and 4.01 shall not constitute an Event of
Default under Section 5.01 ("Covenant Defeasance"), with the remainder of this
Indenture and such Securities unaffected thereby if:

<PAGE>
                                      -61-

                  (1) the Company has irrevocably deposited or caused to be
         irrevocably deposited with the Trustee as trust funds in trust for the
         purpose of making the following payments dedicated solely to the
         benefit of the Holders (i) cash in an amount, or (ii) U.S. Government
         Obligations or (iii) a combination thereof, sufficient, in the opinion
         of a nationally recognized firm of independent public accountants
         expressed in a written certification thereof delivered to the Trustee,
         to pay, without consideration of the reinvestment of any such amounts
         and after payment of all taxes or other charges or assessments in
         respect thereof payable by the Trustee, the principal of and premium,
         if any, Liquidated Damages, if any, Additional Amounts, if any and
         interest on all Securities of such series on each date that such
         principal, premium, if any, Liquidated Damages, if any, Additional
         Amounts, if any, or interest is due and payable and to pay all other
         sums payable by it hereunder; provided that the Trustee shall have been
         irrevocably instructed to apply such money and/or the proceeds of such
         U.S. Government Obligations to the payment of said principal, premium,
         if any, Liquidated Damages, if any, Additional Amounts, if any, and
         interest with respect to the Securities of such series as the same
         shall become due;

                  (2) the Company has delivered to the Trustee an Officers'
         Certificate stating that all conditions precedent to the Covenant
         Defeasance contemplated by this provision with respect to Securities of
         such series have been complied with, and an Opinion of Counsel to the
         same effect;

                  (3) no Default or Event of Default shall have occurred and be
         continuing on the date of such deposit or, insofar as clauses (5) and
         (6) of Section 5.01 are concerned, at any time during the period ending
         on the 91st day after the date of such deposit (it being understood
         that this condition shall not be deemed satisfied until the expiration
         of such period);

                  (4) the Company shall have delivered to the Trustee Opinions
         of Counsel from nationally recognized counsel acceptable to the Trustee
         or a tax ruling to the effect that the Holders of Securities of such
         series will not recognize income, gain or loss for U.S. or Canadian
         Federal income tax purposes as a result of the Company's exercise of
         its option under this Section 7.01(c) and will be subject to U.S. or
         Canadian Federal income tax on the same amounts, in the same manner and
         at the same times as would have been the case if such option had not
         been exercised;

                  (5) such Covenant Defeasance will not result in a breach or
         violation of, or constitute a default under, any other agreement or
         instrument to which the Company or the Guarantor is a party or by which
         it is bound;

                  (6) such Covenant Defeasance shall not cause the Trustee to
         have a conflicting interest as defined in TIA Section 310(b); and

<PAGE>
                                      -62-

                  (7) the Company shall have delivered to the Trustee an Opinion
         of Counsel to the effect that after the passage of 91 days following
         the deposit, the trust funds will not be subject to the effect of any
         applicable bankruptcy, insolvency, reorganization or similar laws
         affecting creditors' rights generally.

                  In order to have money available on a payment date to pay
principal of or premium, if any, Liquidated Damages, if any, Additional Amounts,
if any, or interest on the Securities of such series, the U.S. Government
Obligations shall be payable as to principal or interest on or before such
payment date in such amounts as will provide the necessary money. U.S.
Government Obligations shall not be callable at the issuer's option.

SECTION 7.02. Application of Trust Money.

                  The Trustee or a trustee satisfactory to the Trustee and the
Company shall hold in trust money or U.S. Government Obligations deposited with
it pursuant to Section 7.01. It shall apply the deposited money and the money
from U.S. Government Obligations through the Paying Agent and in accordance with
this Indenture to the payment of principal of and premium, if any, Liquidated
Damages, if any, Additional Amounts, if any, and interest on Securities of the
series with respect to which the deposit was made.

SECTION 7.03. Repayment to Company.

                  The Trustee and the Paying Agent shall promptly pay to the
Company upon written request any excess money or securities held by them at any
time.

                  Subject to the requirements of any applicable abandoned
property laws, the Trustee and the Paying Agent shall pay to the Company upon
written request any money held by them for the payment of principal, premium, if
any, Liquidated Damages, if any, Additional Amounts, if any, or interest that
remains unclaimed for two years after the date upon which such payment shall
have become due; provided, however, that the Company shall have either caused
notice of such payment to be mailed to each Holder entitled thereto no less than
30 days prior to such repayment or within such period shall have published such
notice in a financial newspaper of widespread circulation published in The City
of New York. After payment to the Company, Holders entitled to the money must
look to the Company for payment as general creditors unless an applicable
abandoned property law designates another Person, and all liability of the
Trustee and the Paying Agent with respect to such money shall cease.

SECTION 7.04. Reinstatement.

                  If the Trustee or the Paying Agent is unable to apply any
money or U.S. Government Obligations in accordance with Section 7.01 by reason
of any legal proceeding or by

<PAGE>
                                      -63-

reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the
obligations of the Company and the Guarantor under this Indenture and the
Securities of the applicable series shall be revived and reinstated as though no
deposit had occurred pursuant to Section 7.01 until such time as the Trustee or
the Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with Section 7.01; provided, however, that if the
Company or the Guarantor has made any payment of principal of or interest on any
Securities of such series because of the reinstatement of its obligations, the
Company or the Guarantor, as the case may be, shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money or U.S.
Government Obligations held by the Trustee or the Paying Agent.

SECTION 8.01. Without Consent of Holders.

                  The Company, the Guarantor and the Trustee may amend or
supplement this Indenture or any of the Securities or waive any provision hereof
or thereof without the consent of any Holder:

                  (1) to convey, transfer, assign, mortgage or pledge to the
         Trustee as security for the Securities of one or more series any
         property or assets;

                  (2) to evidence the succession of another entity to the
         Company or the Guarantor, or successive successions, and the assumption
         by the successor entity of the covenants, agreements and obligations of
         the Company or the Guarantor pursuant to Section 4.01 or 4.02;

                  (3) to add to the covenants of the Company or the Guarantor
         such further covenants, restrictions, conditions or provisions as the
         Company or the Guarantor and the Trustee shall consider to be for the
         protection of the Holders of Securities of one or more series, to
         surrender any right or power herein conferred upon the Company or the
         Guarantor, and to make the occurrence, or the occurrence and
         continuance, of a default in any such additional covenants,
         restrictions, conditions or provisions of an Event of Default
         permitting the enforcement of all or any of the several remedies
         provided in this Indenture as herein set forth, provided that in
         respect of any such additional covenant, restriction, condition or
         provision such amendment or supplemental indenture may provide for a
         particular period of grace after default (which period may be shorter
         or longer than that allowed in the case of other defaults) or may
         provide for an

<PAGE>
                                      -64-

         immediate enforcement upon such an Event of Default or may limit the
         remedies available to the Trustee upon such an Event of Default or may
         limit the right of the Holders of a majority in aggregate principal
         amount of the Securities of such series to waive such an Event of
         Default;

                  (4) to cure any ambiguity or to correct or supplement any
         provision contained herein or in any supplemental indenture which may
         be defective or inconsistent with any other provision contained herein
         or in any supplemental indenture, provided that no such action shall
         adversely affect the interests of the Holders of the Securities;

                  (5) to evidence and provide for the acceptance of appointment
         hereunder by a successor trustee with respect to the Securities of one
         or more series and to add to or change any of the provisions of this
         Indenture as shall be necessary to provide for or facilitate the
         administration of the trusts hereunder by more than one trustee,
         pursuant to the requirements of Section 6.08 or 6.09.

                  (6) to provide for uncertificated Securities in addition to or
         in place of certificated Securities;

                  (7) to comply with any requirements, including the requirement
         of the SEC, in order to effect or maintain the qualification of this
         Indenture under the TIA;

                  (8) to comply with the rules or regulations of any securities
         exchange or automated quotation system on which any of the Securities
         may be listed or traded; and

                  (9) to make any change that does not adversely affect the
         rights of any Holder; and

                  (10) to effect the substitution of Devon HoldCo as the Parent
         hereunder and the addition of Devon HoldCo as a "Guarantor" hereunder,
         in each case as contemplated in connection with a Mitchell
         Restructuring Event pursuant to Section 11.18, and to make all such
         other modifications as are necessary or desirable in light of such
         Mitchell Restructuring Event to accomplish the transactions described
         in Section 11.18 or as are not inconsistent herewith and do not
         adversely affect the rights of any Holder.

                  Upon the request of the Company and the Guarantor accompanied
by a resolution of the Board of Directors of each of the Company and of the
Guarantor authorizing the execution of any such supplemental indenture, and upon
receipt by the Trustee of the documents described in Section 8.06, the Trustee
shall join with the Company and the Guarantor in the execution of any
supplemental indenture authorized or permitted by the terms of this

<PAGE>
                                      -65-

Indenture and make any further appropriate agreements and stipulations that may
be therein contained. After an amendment, supplement or waiver under this
Section 8.01 becomes effective, the Company shall mail to the Holders of each
Security affected thereby a notice briefly describing the amendment, supplement
or waiver. Any failure of the Company to mail such notice, or any defect
therein, shall not, however, in any way impair or affect the validity of any
such supplemental indenture.

SECTION 8.02. With Consent of Holders.

                  Except as provided below in this Section 8.02, the Company,
the Guarantor and the Trustee may amend or supplement this Indenture with
respect to the Securities of any series with the written consent (including
consents obtained in connection with a tender offer or exchange offer for the
Securities of such series or a solicitation of consents in respect of the
Securities of such series, provided that in each case such offer or solicitation
is made to all Holders of the Securities of such series then outstanding on
equal terms) of the Holders of at least a majority in principal amount of the
Securities of such series then outstanding affected thereby.

                  Upon the request of the Company and the Guarantor accompanied
by a resolution of the Board of Directors of each of the Company and of the
Guarantor authorizing the execution of any such supplemental indenture, and upon
the filing with the Trustee of evidence of the consent of the Holders as
aforesaid, and upon receipt by the Trustee of the documents described in Section
8.06, the Trustee shall join with the Company and the Guarantor in the execution
of such supplemental indenture.

                  It shall not be necessary for the consent of the Holders under
this Section 8.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

                  The Holders of a majority in principal amount of the
Securities of any series then outstanding may waive compliance in a particular
instance by the Company or the Guarantor with any provision of this Indenture or
the Securities of such series (including waivers obtained in connection with a
tender offer or exchange offer for the Securities of such series or a
solicitation of consents in respect of the Securities of such series, provided
that in each case such offer or solicitation is made to all Holders of the
Securities of such series then outstanding on equal terms).

                  Without the consent of each Holder affected, an amendment,
supplement or waiver under this Section 8.02 may not:

                  (1) extend the final maturity of the principal of any of the
         Securities;

<PAGE>
                                      -66-

                  (2) reduce the principal amount of any of the Securities;

                  (3) reduce the rate or extend the time of payment of interest,
         including default interest, or Additional Amounts, if any, on any of
         the Securities;

                  (4) reduce any amount payable on redemption of any of the
         Securities;

                  (5) change the currency in which the principal of or premium,
         if any, Additional Amounts, if any, or interest on any of the
         Securities is payable;

                  (6) impair the right to institute suit for the enforcement of
         any payment of principal of or premium, if any, Additional Amounts, if
         any, or interest on any Security pursuant to Sections 5.07 and 5.08,
         except as limited by Section 5.06;

                  (7) make any change in the percentage of principal amount of
         the Securities of any series necessary to waive compliance with or to
         modify certain provisions of this Indenture pursuant to Section 5.04 or
         5.07 or this clause of this Section 8.02; or

                  (8) waive a continuing Default or Event of Default in the
         payment of principal of or premium, if any, Liquidated Damages, if any,
         Additional Amounts, if any, or interest, including default interest, on
         the Securities of any series.

                  The right of any Holder to participate in any consent required
or sought pursuant to any provision of this Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of the Securities with respect to which such consent is required or sought as of
a date identified by the Trustee in a notice furnished to Holders in accordance
with the terms of this Indenture.

SECTION 8.03. Compliance with Trust Indenture Act.

                  Every amendment to this Indenture or the Securities of any
series shall comply in form and substance with the TIA as then in effect.

SECTION 8.04. Revocation and Effect of Consents.

                  A consent to an amendment (which includes a supplement) or
waiver by a Holder is a continuing consent by the Holder and every subsequent
Holder of a Security of any series or portion of a Security of such series that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent is not made on any Security. However, any such Holder or subsequent
Holder may revoke the consent as to his Security or portion of a Security if the
Trustee receives written notice of revocation at any time prior to (but not
after) the date the Trustee receives an Officers' Certificate certifying that
the Holders of the requisite

<PAGE>
                                      -67-

principal amount of Securities have consented (and not theretofore revoked such
consent) to the amendment, supplement or waiver. An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every
Holder.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to consent to any
amendment or waiver or to take any other action with respect to the Securities
of any series under this Indenture. If a record date is fixed, then
notwithstanding the provisions of the immediately preceding paragraph, those
Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to consent to such amendment,
supplement or waiver or to revoke any consent previously given, whether or not
such Persons continue to be Holders after such record date. No consent shall be
valid or effective for more than 90 days after such record date unless consents
from Holders of the principal amount of the Securities of such series required
hereunder for such amendment or waiver to be effective shall have also been
given and not revoked within such 90-day period.

                  After an amendment, supplement or waiver becomes effective, it
shall bind every Holder, unless it is of the type described in any of clauses
(1) through (8) of Section 8.02. In such case, the amendment, supplement or
waiver shall bind each Holder who has consented to it and every subsequent
Holder that evidences the same debt as the consenting Holder's Security.

SECTION 8.05. Notation on or Exchange of Securities.

                  If an amendment changes the terms of a Security, the Trustee
may require the Holder of the Security to deliver it to the Trustee. The Trustee
may place an appropriate notation on the Security regarding the changed terms
and return it to the Holder. Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Security shall issue and the Trustee
shall authenticate a new Security that reflects the changed terms. Failure to
make the appropriate notation or to issue a new Security shall not affect the
validity of such amendment.

SECTION 8.06. Trustee to Sign Amendments, etc.

                  The Trustee shall sign any amendment, waiver or supplemental
indenture authorized pursuant to this Article VIII if the amendment, waiver or
supplemental indenture does not adversely affect the rights, duties, liabilities
or immunities of the Trustee. If it does, the Trustee may, but need not, sign
it. In signing or refusing to sign such amendment, waiver or supplemental
indenture, the Trustee shall receive, and subject to Section 6.01, shall be
fully protected in relying upon, an Opinion of Counsel and an Officers'
Certificate, as conclusive evidence that such amendment, waiver or supplemental
indenture is authorized or permitted

<PAGE>
                                      -68-

by this Indenture, that it is not inconsistent herewith, and that it will be
valid and binding upon the Company and the Guarantor in accordance with its
terms.

                                   ARTICLE IX

                            GUARANTEES OF SECURITIES

SECTION 9.01. Unconditional Guarantees.

                  (a) For value received, the Guarantor hereby fully,
irrevocably, unconditionally and absolutely guarantees to the Holders and to the
Trustee the due and punctual payment of the principal of and premium, if any,
Liquidated Damages, if any, Additional Amounts, if any, and interest on the
Securities and all other amounts due and payable under this Indenture and the
Securities by the Company (including, without limitation, all costs and expenses
(including reasonable legal fees and disbursements) incurred by the Trustee or
the Holders in connection with the enforcement of this Indenture, the Securities
and the Guarantees) (collectively, the "Indenture Obligations"), when and as
such principal, premium, if any, Liquidated Damages, if any, Additional Amounts,
if any, and interest and such other amounts shall become due and payable,
whether at the Stated Maturity, upon redemption or by declaration of
acceleration or otherwise, according to the terms of the Securities and this
Indenture. The guarantees by the Guarantor set forth in this Article IX are
referred to herein as the "Guarantees." Without limiting the generality of the
foregoing, the Guarantor's liability shall extend to all amounts that constitute
part of the Indenture Obligations and would be owed by the Company under this
Indenture and the Securities but for the fact that they are unenforceable,
reduced, limited, impaired, suspended or not allowable due to the existence of a
bankruptcy, reorganization or similar proceeding involving the Company.

                  (b) Failing payment when due of any amount guaranteed pursuant
to the Guarantees, for whatever reason, the Guarantor will be obligated to pay
the same immediately to the Trustee, without set-off or counterclaim or other
reduction whatsoever (whether for taxes, withholding or otherwise). Each
Guarantee hereunder is intended to be a general, unsecured, senior obligation of
the Guarantor and will rank pari passu in right of payment with all Indebtedness
of the Guarantor that is not, by its terms, expressly subordinated in right of
payment to the Guarantees of the Guarantor. The Guarantor hereby agrees that its
obligations hereunder shall be full, irrevocable, unconditional and absolute,
irrespective of the validity, regularity or enforceability of the obligations
and liabilities of any other obligor with respect to the Securities, the
Guarantees or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder with respect to any provisions hereof or thereof
with respect to the same, the recovery of any judgment against the Company, or
any other circumstance which might otherwise constitute a legal or equitable
discharge or defense of the Guarantor.

<PAGE>
                                      -69-

The Guarantor hereby agrees that in the event of a default in payment of the
principal of or premium, if any, Liquidated Damages, if any, Additional Amounts,
if any, or interest on the Securities of any series or any other amounts payable
under this Indenture and the Securities by the Company, whether at the Stated
Maturity, upon redemption or by declaration of acceleration or otherwise, legal
proceedings may be instituted by the Trustee on behalf of the Holders or,
subject to Section 5.06, by the Holders, on the terms and conditions set forth
in this Indenture, directly against the Guarantor to enforce the Guarantees
without first proceeding against the Company.

                  (c) To the fullest extent permitted by applicable law, the
obligations of the Guarantor under this Article IX shall be as aforesaid full,
irrevocable, unconditional and absolute and shall not be impaired, modified,
discharged, released or limited by any occurrence or condition whatsoever,
including, without limitation, (i) any compromise, settlement, release, waiver,
renewal, extension, indulgence or modification of, or any change in, any of the
obligations and liabilities of any other obligor with respect to the Securities
contained in any of the Securities or this Indenture, (ii) any impairment,
modification, release or limitation of the liability of the Company, the
Guarantor or any of their respective estates in bankruptcy, or any remedy for
the enforcement thereof, resulting from the operation of any present or future
provision of any applicable Bankruptcy Law, as amended, or other statute or from
the decision of any court, (iii) the assertion or exercise by the Company, the
Guarantor or the Trustee of any rights or remedies under any of the Securities
or this Indenture or its delay in or failure to assert or exercise any such
rights or remedies, (iv) the assignment or the purported assignment of any
property as security for any of the Securities, including all or any part of the
rights of the Company or the Guarantor under this Indenture, (v) the extension
of the time for payment by the Company or the Guarantor of any payments or other
sums or any part thereof owing or payable under any of the terms and provisions
of any of the Securities or this Indenture or of the time for performance by the
Company or the Guarantor of any other obligations under or arising out of any
such terms and provisions or the extension or the renewal of any thereof, (vi)
the modification or amendment (whether material or otherwise) of any duty,
agreement or obligation set forth in this Indenture of any other obligor with
respect to the Securities, (vii) the voluntary or involuntary liquidation,
dissolution, sale or other disposition of all or substantially all of the
assets, marshaling of assets and liabilities, receivership, insolvency,
bankruptcy, assignment for the benefit of creditors, reorganization,
arrangement, composition or readjustment of, or other similar proceeding
affecting, the Company or any of the Guarantor or any of their respective
assets, or the disaffirmance of any of the Securities, the Guarantees or this
Indenture in any such proceeding, (viii) the release or discharge of the Company
or the Guarantor from the performance or observance of any agreement, covenant,
term or condition contained in any of such instruments by operation of law, (ix)
the unenforceability of any of the obligations of any of the other obligors
under the Securities, the Guarantees or this Indenture, (x) any change in the
name, business, capital structure, corporate existence, or ownership

<PAGE>
                                      -70-

of the Company or the Guarantor, or (xi) any other circumstance which might
otherwise constitute a defense available to, or a legal or equitable discharge
of, a surety or the Guarantor.

                  (d) The Guarantor hereby (i) waives diligence, presentment,
demand of payment, notice of acceptance, filing of claims with a court in the
event of the merger, insolvency or bankruptcy of the Company or the Guarantor,
and all demands and notices whatsoever, (ii) acknowledges that any agreement,
instrument or document evidencing the Guarantees may be transferred and that the
benefit of its obligations hereunder shall extend to each holder of any
agreement, instrument or document evidencing the Guarantees without notice to
them and (iii) covenants that its Guarantees will not be discharged except by
complete performance of the Guarantees or of the obligations guaranteed thereby.
The Guarantor further agrees that if at any time all or any part of any payment
theretofore applied by any Person to any Guarantee is, or must be, rescinded or
returned for any reason whatsoever, including, without limitation, the
insolvency, bankruptcy or reorganization of the Guarantor, such Guarantee shall,
to the extent that such payment is or must be rescinded or returned, be deemed
to have continued in existence notwithstanding such application, and the
Guarantees shall continue to be effective or be reinstated, as the case may be,
as though such application had not been made.

                  (e) The Guarantor shall be subrogated to all rights of the
Holders and the Trustee against the Company in respect of any amounts paid by
the Guarantor pursuant to the provisions of this Indenture; provided, however,
that the Guarantor shall not be entitled to enforce or to receive any payments
arising out of, or based upon, such right of subrogation with respect to any of
the Securities until all of the Securities and the Guarantees thereof shall have
been paid in full or discharged.

                  (f) A director, officer, employee or stockholder, as such, of
the Guarantor shall not have any liability for any obligations of the Guarantor
under this Indenture or for any claim based on, in respect of or by reason of
such obligations or their creation.

                  (g) No failure to exercise and no delay in exercising, on the
part of the Trustee or the Holders, any right, power, privilege or remedy under
this Article IX and the Guarantees shall operate as a waiver thereof, nor shall
any single or partial exercise of any rights, power, privilege or remedy
preclude any other or further exercise thereof, or the exercise of any other
rights, powers, privileges or remedies. The rights and remedies herein provided
for are cumulative and not exclusive of any rights or remedies provided in law
or equity. Nothing contained in this Article IX shall limit the right of the
Trustee or the Holders to take any action to accelerate the maturity of the
Securities pursuant to Article V or to pursue any rights or remedies hereunder
or under applicable law.

SECTION 9.02. Execution and Delivery of Notation of Guarantees.

                  To further evidence the Guarantees, the Guarantor hereby
agrees that on the date of this Indenture a notation of such Guarantees shall be
endorsed on each Security authenticated and delivered by the Trustee and
executed by either manual or facsimile signature of an Officer of Devon Energy
Corporation.

                  The Guarantor hereby agrees that its Guarantees shall remain
in full force and effect notwithstanding any failure to endorse on each Security
a notation relating to the Guarantee thereof.

                  If an Officer of the Guarantor whose signature is on this
Indenture or a Security no longer holds that office, or if any other or
additional Person shall have become a "Guarantor" hereunder in accordance with
Section 4.01, 4.02 and/or 11.18 hereof, at the time the Trustee authenticates
such Security or at any time thereafter, the Guarantor's Guarantee of such
Security shall be valid nevertheless.

                  The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of any Guarantee
set forth in this Indenture on behalf of the Guarantor and each other Person
which may at such time constitute the "Guarantor" hereunder.

                                    ARTICLE X

                                   REDEMPTION

SECTION 10.01. Notices to Trustee.

                  If the Company elects to redeem the Securities of any series
pursuant to the redemption provisions of Section 10.07, it shall furnish to the
Trustee, at least 30 days but not more than 60 days before a Redemption Date, an
Officers' Certificate setting forth the Redemption Date, the principal amount of
such Securities to be redeemed and the Redemption Price (or the method of
calculating the Redemption Price).

SECTION 10.02. Selection of Securities to be Redeemed.

                  If less than all of the Securities of a series are to be
redeemed, the Trustee shall select the Securities of such series to be redeemed
by such method as the Trustee in its sole discretion shall deem fair and
appropriate. The particular Securities of such series to be redeemed shall be
selected, unless otherwise provided herein, not less than 30 days nor more

<PAGE>
                                      -72-

than 60 days prior to the Redemption Date by the Trustee from the outstanding
Securities of such series not previously called for redemption.

                  The Trustee shall promptly notify the Company in writing of
the Securities of such series selected for redemption and, in the case of any
Security selected for partial redemption, the principal amount thereof to be
redeemed. Securities and portions of them selected shall be in amounts of $1,000
or integral multiples thereof. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Securities called for redemption also
apply to portions of Securities called for redemption.

SECTION 10.03. Notices to Holders.

                  (a) At least 30 days but not more than 60 days before a
Redemption Date, the Company shall mail in conformity with Section 11.02 a
notice of redemption to each Holder whose Securities are to be redeemed. The
notice shall identify the Securities to be redeemed (including CUSIP numbers, if
any) and shall state:

                  (i) the Redemption Date;

                  (ii) the Redemption Price (or the method of calculating the
         Redemption Price);

                  (iii) if any Security is being redeemed in part, the portion
         of the principal amount of such Security to be redeemed and that, after
         the Redemption Date, upon surrender of such Security, a new Security or
         Securities in principal amount equal to the unredeemed portion will be
         issued;

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

                  (v) that Securities called for redemption must be surrendered
         to the Paying Agent at the address specified in such notice to collect
         the Redemption Price;

                  (vi) that unless the Company defaults in making the redemption
         payment, interest on Securities called for redemption ceases to accrue
         on and after the Redemption Date and the only remaining right of the
         Holders is to receive payment of the Redemption Price upon surrender to
         the Paying Agent of the Securities; and

                  (vii) the aggregate principal amount of Securities of each
         series being redeemed.

                  If any of the Securities to be redeemed is in the form of a
Global Security, then the Company shall modify such notice to the extent
necessary to accord with the procedures of the Depositary applicable to
redemptions.

<PAGE>
                                      -73-

                  (b) At the Company's request, the Trustee shall give the
notice required in Section 10.03(a) in the Company's name; provided, however,
that the Company shall deliver to the Trustee, at least 45 days prior to the
Redemption Date (unless the Trustee consents in writing to a shorter period at
least 30 days prior to the Redemption Date), an Officers' Certificate requesting
that the Trustee give such notice and setting forth the information to be stated
in such notice as provided in Section 10.03(a).

SECTION 10.04. Effect of Notices of Redemption.

                  Once notice of redemption is mailed pursuant to Section 10.03,
Securities called for redemption become due and payable on the Redemption Date
at the Redemption Price. Upon surrender to the Paying Agent, such Securities
shall be paid out at the Redemption Price.

SECTION 10.05. Deposit of Redemption Price.

                  At or prior to 10:00 a.m. New York City time on the Redemption
Date, the Company shall deposit with the Trustee or with the Paying Agent
immediately available funds sufficient to pay the Redemption Price of all
Securities to be redeemed on that date. The Trustee or the Paying Agent shall
return to the Company any money not required for that purpose less the expenses

case at the rate provided in the Securities and in Section 3.01.

                           REVERSE OF 10-YEAR SECURITY

                       DEVON FINANCING CORPORATION, U.L.C.

                         6.875% SERIES A/B NOTE DUE 2011

                  This Security is one of a duly authorized issue of 6.875%
Series A/B Notes due 2011 (the "Securities") of Devon Financing Corporation,
U.L.C., an unlimited liability company organized under the laws of the province
of Nova Scotia, Canada (the "Company").

                  1. Interest. The Company promises to pay interest on the
principal amount of this Security at 6.875% per annum from October 3, 2001 until
maturity. The Company will pay interest semiannually on March 30 and September
30 of each year (each an "Interest Payment Date"), or if any such day is not a
Business Day, on the next succeeding Business Day. Interest on this Security
will accrue from the most recent Interest Payment Date on which interest has
been paid or, if no interest has been paid, from October 3, 2001; provided that
if there is no existing Default in the payment of interest, and if this Security
is authenticated between a record date referred to on the face hereof and the
next succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date. Further, the Company shall pay interest on
overdue principal, premium, if any, Liquidated Damages, if any, and Additional
Amounts, if any, from time to time on demand at a rate equal to the interest
rate then in effect; it shall pay interest, Liquidated Damages, if any, and
Additional Amounts, if any, on overdue installments of interest (without regard
to any applicable grace periods) from time to time on demand at the same rate to
the extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

                  2. Method of Payment. The Company will pay interest on this
Security (except defaulted interest) to the Persons who are registered Holders
of this Security at the close of business on the record date next preceding the
Interest Payment Date, even if this Security is canceled after such record date
and on or before such Interest Payment Date. The Holder must surrender this
Security to a Paying Agent to collect payments of principal, premium, if any,
Liquidated Damages, if any, and Additional Amounts, if any. The Company will pay
the principal of and premium, if any, Liquidated Damages, if any, and Additional
Amounts, if any, and interest on this Security in money of the United States of
America that at the time of payment is legal tender for payment of public and
private debts. Payments in respect of the Securities represented by a Global
Security (including principal, premium, if any, Liquidated Damages, if any,
Additional Amounts, if any, and interest) will be made by wire transfer of
immediately available funds to the accounts specified by The Depository Trust
Company; provided that if no account is specified, the Company may choose to
make payment at the Corporate Trust Office of the Trustee or by mailing a check
to the Holder's registered address. The Company will make all payments in
respect of a certificated Security (including principal, premium, if any,
Liquidated Damages, if any, Additional Amounts, if any, and interest) by mailing
a check to the registered address of each Holder thereof; provided, however,
that

                                      A-6
<PAGE>

payments on a certificated Security will be made by wire transfer to a U.S.
dollar account maintained by the payee with a bank in the United States if such
Holder elects payment by wire transfer by giving written notice to the Trustee
or the Paying Agent to such effect designating such account no later than 30
days immediately preceding the relevant due date for payment (or such other date
as the Trustee may accept in its discretion).

                  3. Ranking and Guarantees. This Security is a senior unsecured
obligation of the Company and is guaranteed pursuant to a guarantee (the
"Guarantee") by Devon Energy Corporation, a Delaware corporation, and each other
Person, if any, named as the Guarantor in the Indenture (together, the
"Guarantor"). The Guarantee is a senior unsecured obligation of the Guarantor.
References herein to the Indenture or the Securities shall be deemed also to
refer to the Guarantees set forth in the Indenture except where the context
otherwise requires.

                  4. Optional Redemption. This Security will be redeemable, in
whole or in part, at any time, at the Company's option, at a redemption price
equal to the greater of (1) 100% of the principal amount of this Security then
outstanding to be redeemed, or (2) the sum of the present values of the
remaining scheduled payments of principal and interest thereon (exclusive of
interest accrued to the Redemption Date) computed by discounting such payments
to the Redemption Date on a semiannual basis (assuming a 360-day year consisting
of twelve 30-day months) at a rate equal to the sum of 30 basis points plus the
Adjusted Treasury Rate on the third Business Day prior to the Redemption Date,
as calculated by an Independent Investment Banker, plus accrued and unpaid
interest, up to, but not including the Redemption Date.

                  "Adjusted Treasury Rate" means, with respect to any Redemption
Date, the yield, under the heading which represents the average for the
immediately preceding week, appearing in the most recently published statistical
release designated "H.15(519)" or any successor publication which is published
weekly by the Board of Governors of the Federal Reserve System and which
establishes yields on actively traded U.S. Treasury securities adjusted to
constant maturity under the caption "Treasury Constant Maturities" for the
maturity corresponding to the Optional Redemption Comparable Treasury Issue (if
no maturity is within three months before or after the remaining term of this
Security, yields for the two published maturities most closely corresponding to
the Optional Redemption Comparable Treasury Issue will be determined and the
Adjusted Treasury Rate will be interpolated or extrapolated from such yields on
a straight line basis, rounding to the nearest month); or if such release (or
any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per annum equal to
the semiannual equivalent yield to maturity of the Optional Redemption
Comparable Treasury Issue, calculated using a price for the Optional Redemption
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Optional Redemption Comparable Treasury Price for such redemption
date.

                                      A-7
<PAGE>

                  "Independent Investment Banker" means UBS Warburg LLC, or if
such firm is unwilling or unable to serve as such, an independent investment and
banking institution of national standing appointed by the Trustee.

                  "Optional Redemption Reference Treasury Dealer" means each of
up to five dealers to be selected by the Company and the Guarantor, and their
respective successors; provided that if any of the foregoing ceases to be, and
has no affiliate that is, a primary U.S. governmental securities dealer (a
"Primary Treasury Dealer"), the Company and the Guarantor will substitute for it
another Primary Treasury Dealer.

                  "Optional Redemption Comparable Treasury Issue" means the U.S.
Treasury security selected by an Independent Investment Banker as having a
maturity comparable to the remaining term of the Securities to be redeemed that
would be utilized, at the time of selection and in accordance with customary
financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of this Security, or, if, in the
reasonable judgment of the Independent Investment Banker, there is no such
security, then the Optional Redemption Comparable Treasury Issue will mean the
U.S. Treasury security or securities selected by the Independent Investment
Banker as having an actual or interpolated maturity or maturities comparable to
the remaining term of this Security.

                  "Optional Redemption Comparable Treasury Price" means (1) the
average of five Optional Redemption Reference Treasury Dealer Quotations for the
applicable redemption date, after excluding the highest and lowest Optional
Redemption Reference Treasury Dealer Quotations, or (2) if the Independent
Investment Banker obtains fewer than five such Optional Redemption Reference
Treasury Dealer Quotations, the average of all such quotations.

                  "Optional Redemption Reference Treasury Dealer Quotations"
means, with respect to each Optional Redemption Reference Treasury Dealer and
any Redemption Date for this Security, the average, as determined by the
Independent Investment Banker of the bid and asked prices for the Optional
Redemption Comparable Treasury Issue (expressed in each case as a percentage of
its principal amount) quoted in writing to the Independent Investment Banker and
the Trustee at 5:00 p.m., New York City time, on the third Business Day
preceding such Redemption Date.

                  5. Optional Redemption for Changes In Canadian Withholding
Taxes. The Securities will be subject to redemption in whole, but not in part,
at the Company's option and at any time, at a redemption price equal to 100% of
their principal amount, plus accrued and unpaid interest, if any, and Liquidated
Damages, if any, up to, but not including, the Redemption Date, in the event
that either the Company, the Guarantor or any other obligor under the
Securities, as the case may be, has become, or would become, obligated to pay,
on the next date on which any amount would be payable with respect to these
Securities, any Additional Amounts relating to any present or future Taxes, and
provided that the obligation to pay

                                      A-8
<PAGE>

Additional Amounts results from a change in the taxing laws and/or regulations
of Canada that is announced or becomes effective on or after the Issue Date;
provided, however; (1) no notice of redemption will be given earlier than 60
days prior to the earliest date on which the Company, the Guarantor or any other
obligor under the Securities, as the case may be, would be obligated to pay any
of these Additional Amounts if a payment with respect to this Security were then
due; (2) at the time any redemption notice is given, the obligation to pay these
Additional Amounts must remain in effect through the Redemption Date; and (3)
such obligation to pay Additional Amounts cannot be avoided by the Company by
taking reasonable measures available to it that it determines would not have an
adverse impact on it. Prior to any redemption of these Securities under these
provisions, the Company will deliver to the Trustee or any Paying Agent an
Officers' Certificate stating that the Company is entitled to effect the
redemption and setting forth a statement of facts showing that the conditions
precedent to the right of redemption have occurred.

                  6. Paying Agent and Registrar. Initially, The Chase Manhattan
Bank (the "Trustee"), the Trustee under the Indenture, will act as Paying Agent
and Registrar. The Company may change any Paying Agent, Registrar, co-registrar
or additional paying agent without notice to any Holder. The Guarantor or any of
its Subsidiaries may act in any such capacity.

                  7. Indenture. The Company issued this Security under an
Indenture dated as of October 3, 2001 (as amended, supplemented or otherwise
modified from time to time, the "Indenture") among the Company, Devon Energy
Corporation and the Trustee. The terms of this Security include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb), as in
effect on the date of execution of the Indenture. This Security and the
Guarantee are subject to all such terms, and Holders are referred to the
Indenture and such Act for a statement of such terms. Capitalized terms used but
not defined in this Security have the respective meanings given to such terms in
the Indenture.

                  8. Denominations, Transfer, Exchange. This Security is in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of this Security may be registered and this
Security may be exchanged as provided in the Indenture. The Registrar and the
Trustee may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar need not exchange or register
the transfer of this Security during the period between a record date and the
corresponding Interest Payment Date.

                  9. Persons Deemed Owners. The registered Holder of a Security
shall be treated as its owner for all purposes.

                                      A-9
<PAGE>

                  10. Amendments and Waivers. Subject to certain exceptions and
limitations, the Indenture or this Security may be amended or supplemented with
the consent of the Holders of at least a majority in principal amount of the
then outstanding Securities, and compliance in a particular instance by the
Company or the Guarantor with any provision of the Indenture with respect to the
Securities may be waived (other than certain provisions, including any
continuing Default or Event of Default in the payment of the principal of or
premium, if any, Additional Amounts, if any, or interest on these Securities) by
the Holders of at least a majority in principal amount of the Securities then
outstanding in accordance with the terms of the Indenture. Without the consent
of any Holder, the Company, the Guarantor and the Trustee may amend or
supplement the Indenture or this Security to convey, transfer, assign, mortgage
or pledge to the Trustee as security for this Security any property or assets;
to evidence the succession of another entity to the Company or the Guarantor, or

covenants, agreements and obligations of the Company or the Guarantor pursuant
to Section 4.01 or 4.02 of the Indenture; to add to the covenants of the Company
or the Guarantor such further covenants, restrictions, conditions or provisions
as the Company or the Guarantor and the Trustee shall consider to be for the
protection of the Holders of Securities of one or more series, to surrender any
right or power herein conferred upon the Company or the Guarantor, and to make
the occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions, conditions or provisions of an Event of
Default permitting the enforcement of all or any of the several remedies
provided in the Indenture, provided that in respect of any such additional
covenant, restriction, condition or provision such amendment or supplemental
indenture may provide for a particular period of grace after default (which
period may be shorter or longer than that allowed in the case of other defaults)
or may provide for an immediate enforcement upon such an Event of Default or may
limit the remedies available to the Trustee upon such an Event of Default or may
limit the right of the Holders of a majority in aggregate principal amount of
the Securities of such series to waive such an Event of Default; to cure any
ambiguity or to correct or supplement any provision contained in the Indenture
or in any supplemental indenture which may be defective or inconsistent with any
other provision contained in the Indenture or in any supplemental indenture,
provided that no such action shall adversely affect the interests of the Holders
of this Security; to evidence and provide for the acceptance of appointment
under the Indenture by a successor trustee with respect to the Securities of one
or more series and to add to or change any of the provisions of the Indenture as
shall be necessary to provide for or facilitate the administration of the trusts
under the Indenture by more than one trustee, pursuant to the requirements of
Section 6.08 or Section 6.09 of the Indenture; to provide for uncertificated
Securities in addition to or in place of certificated Securities; to comply with
any requirements, including the requirements of the SEC, in order to effect or
maintain the qualification of the Indenture under the TIA; to comply with the
rules or regulations of any securities exchange or automated quotations system
on which any of the Securities may be listed or traded; to make any change that
does not adversely affect the rights under the Indenture of any Holder; and to

the addition of Devon HoldCo as a "Guarantor" under the Indenture, in

                                      A-10
<PAGE>

each case as contemplated in connection with a Mitchell Restructuring Event
pursuant to Section 11.18 of the Indenture, and to make all such other
modifications as are necessary or desirable in light of such Mitchell
Restructuring Event to accomplish the transactions described in Section 11.18 of
the Indenture or as are not inconsistent with the Indenture and do not adversely
affect the rights of any Holder.

                  The right of any Holder to participate in any consent required
or sought pursuant to any provision of the Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of this Security as of a date identified by the Trustee in a notice furnished to
Holders in accordance with the terms of the Indenture.

                  11. Defaults and Remedies. Events of Default include: (i)
default in the payment of the principal of or premium, if any, on any Security

default or breach for a period of 90 days after there has been given, by
registered or certified mail, to the Company and the Guarantor by the Trustee or

Debt of the Company or the Guarantor outstanding in an aggregate principal

stated maturity, and there has been given, by registered or certified mail, to
the Company and the Guarantor by the Trustee or to the Company, the Guarantor
and the Trustee by the Holders of at least 25% in aggregate principal amount of
the outstanding Securities a written notice specifying such default and
requiring it to be remedied and stating that such notice is a "Notice of
Default" hereunder unless (A) such default shall be cured, by payment or
otherwise, within 60 days after the receipt of such notice or (B) the

                  If an Event of Default (other than an Event of Default
specified in clause (5) or (6) of Section 5.01 of the Indenture) with respect to
this Security occurs and is continuing, the Trustee by notice to the Company and

interest to the date of payment. Holders may not enforce the Indenture or this
Security except as provided in the Indenture. The Trustee does require indemnity
reasonably satisfactory to it before it enforces the Indenture or this Security.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding Securities may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders notice of any continuing default
(except a default in payment of principal or

                                      A-12

premium, if any, or interest) if it determines that withholding notice is in
their interests. The Company and the Guarantor each must furnish an annual
compliance certificate to the Trustee.

                  12. Additional Amounts. If the Company is required to withhold
or deduct any amount for or on account of any Taxes for any payment made under

                  13. Discharge Prior to Maturity. The Indenture shall be
discharged and canceled upon the payment of all of the Securities and shall be
discharged except for certain obligations upon the irrevocable deposit with the
Trustee of cash, or U.S. Government Obligations or a combination thereof
sufficient for such payment.

                  14. Trustee Dealings with the Company and the Guarantor. The
Trustee in its individual or any other capacity may become the owner or pledgee
of this Security and may otherwise deal with the Company, the Parent or any of
their Affiliates with the same rights it would have if it were not the Trustee.

                  15. No Recourse Against Others. A director, officer, employee
or stockholder of the Company or the Guarantor, as such, shall not have any
liability for any obligations of the Company or the Guarantor under this
Security, the Guarantee or the Indenture or for any claim based on, in respect
of or by reason of such obligations or their creation. Each Holder by accepting
this Security waives and releases all such liability. The waiver and release are
part of the consideration for the issuance of this Security.

benefit under the Indenture or be valid or obligatory for any purpose until
authenticated by the manual signature of an authorized signatory of the Trustee,
which signature shall be conclusive evidence that this Security has been
authenticated under the Indenture.

                  17. CUSIP Numbers. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused a CUSIP number to be printed on this Security as a convenience to the
Holders of this Security. No representation is made as to the correctness of
such number either as printed on this Security or as contained in any notice of

                      7.875% SERIES A/B DEBENTURE DUE 2031

                  This Security is one of a duly authorized issue of 7.875%
Series A/B Debenture due 2031 (the "Securities") of Devon Financing Corporation,
U.L.C., an unlimited liability company organized under the laws of the province
of Nova Scotia, Canada (the "Company").

                  1. Interest. The Company promises to pay interest on the
principal amount of this Security at 7.875% per annum from October 3, 2001 until
maturity. The Company will pay interest semiannually on March 30 and September
30 of each year (each an "Interest Payment Date"), or if any such day is not a
Business Day, on the next succeeding Business Day. Interest on this Security
will accrue from the most recent Interest Payment Date on which interest has
been paid or, if no interest has been paid, from October 3, 2001; provided that
if there is no existing Default in the payment of interest, and if this Security
is authenticated between a record date referred to on the face hereof and the
next succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date. Further, the Company shall pay interest on
overdue principal, premium, if any, Liquidated Damages, if any, and Additional
Amounts, if any, from time to time on demand at a rate equal to the interest
rate then in effect; it shall pay interest, Liquidated Damages, if any, and
Additional Amounts, if any, on overdue installments of interest (without regard
to any applicable grace periods) from time to time on demand at the same rate to
the extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

                  2. Method of Payment. The Company will pay interest on this
Security (except defaulted interest) to the Persons who are registered Holders
of this Security at the close of business on the record date next preceding the
Interest Payment Date, even if this Security is canceled after such record date
and on or before such Interest Payment Date. The Holder must surrender this
Security to a Paying Agent to collect payments of principal, premium, if any,
Liquidated Damages, if any, and Additional Amounts, if any. The Company will pay
the principal of and premium, if any, Liquidated Damages, if any, and Additional
Amounts, if any, and interest on this Security in money of the United States of
America that at the time of payment is legal tender for payment of public and
private debts. Payments in respect of the Securities represented by a Global
Security (including principal, premium, if any, Liquidated Damages, if any,
Additional Amounts, if any, and interest) will be made by wire transfer of
immediately available funds to the accounts specified by The Depository Trust
Company; provided that if no account is specified, the Company may choose to
make payment at the Corporate Trust Office of the Trustee or by mailing a check
to the Holder's registered address. The Company will make all payments in
respect of a certificated Security (including principal, premium, if any,
Liquidated Damages, if any, Additional Amounts, if any, and interest) by

                                      B-6
<PAGE>

mailing a check to the registered address of each Holder thereof; provided,
however, that payments on a certificated Security will be made by wire transfer
to a U.S. dollar account maintained by the payee with a bank in the United
States if such Holder elects payment by wire transfer by giving written notice
to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

                  3. Ranking and Guarantees. This Security is a senior unsecured
obligation of the Company and is guaranteed pursuant to a guarantee (the
"Guarantee") by Devon Energy Corporation, a Delaware corporation, and each other
Person, if any, named as the Guarantor in the Indenture (together, the
"Guarantor"). The Guarantee is a senior unsecured obligation of the Guarantor.
References herein to the Indenture or the Securities shall be deemed also to
refer to the Guarantees set forth in the Indenture except where the context
otherwise requires.

                  4. Optional Redemption. This Security will be redeemable, in
whole or in part, at any time, at the Company's option, at a redemption price
equal to the greater of (1) 100% of the principal amount of this Security then
outstanding to be redeemed, or (2) the sum of the present values of the
remaining scheduled payments of principal and interest thereon (exclusive of
interest accrued to the Redemption Date) computed by discounting such payments
to the Redemption Date on a semiannual basis (assuming a 360-day year consisting
of twelve 30-day months) at a rate equal to the sum of 30 basis points plus the
Adjusted Treasury Rate on the third Business Day prior to the Redemption Date,
as calculated by an Independent Investment Banker, plus accrued and unpaid
interest, up to, but not including the Redemption Date.

                  "Adjusted Treasury Rate" means, with respect to any Redemption
Date, the yield, under the heading which represents the average for the
immediately preceding week, appearing in the most recently published statistical
release designated "H.15(519)" or any successor publication which is published
weekly by the Board of Governors of the Federal Reserve System and which
establishes yields on actively traded U.S. Treasury securities adjusted to
constant maturity under the caption "Treasury Constant Maturities" for the
maturity corresponding to the Optional Redemption Comparable Treasury Issue (if
no maturity is within three months before or after the remaining term of this
Security, yields for the two published maturities most closely corresponding to
the Optional Redemption Comparable Treasury Issue will be determined and the
Adjusted Treasury Rate will be interpolated or extrapolated from such yields on
a straight line basis, rounding to the nearest month); or if such release (or
any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per annum equal to
the semiannual equivalent yield to maturity of the Optional Redemption
Comparable Treasury Issue, calculated using a price for the Optional Redemption
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Optional Redemption Comparable Treasury Price for such redemption
date.

                  "Independent Investment Banker" means UBS Warburg LLC, or if
such firm is unwilling or unable to serve as such, an independent investment and
banking institution of national standing appointed by the Trustee.

                  "Optional Redemption Reference Treasury Dealer" means each of
up to five dealers to be selected by the Company and the Guarantor, and their
respective successors; provided that if any of the foregoing ceases to be, and
has no affiliate that is, a primary U.S. governmental securities dealer (a
"Primary Treasury Dealer"), the Company and the Guarantor will substitute for it
another Primary Treasury Dealer.

                  "Optional Redemption Comparable Treasury Issue" means the U.S.
Treasury security selected by an Independent Investment Banker as having a
maturity comparable to the remaining term of the Securities to be redeemed that
would be utilized, at the time of selection and in accordance with customary
financial practice, in pricing new issues of corporate debt securities of
comparable maturity to the remaining term of this Security, or, if, in the
reasonable judgment of the Independent Investment Banker, there is no such
security, then the Optional Redemption Comparable Treasury Issue will mean the
U.S. Treasury security or securities selected by the Independent Investment
Banker as having an actual or interpolated maturity or maturities comparable to
the remaining term of this Security.

                  "Optional Redemption Comparable Treasury Price" means (1) the
average of five Optional Redemption Reference Treasury Dealer Quotations for the
applicable redemption date, after excluding the highest and lowest Optional
Redemption Reference Treasury Dealer Quotations, or (2) if the Independent
Investment Banker obtains fewer than five such Optional Redemption Reference
Treasury Dealer Quotations, the average of all such quotations.

                  "Optional Redemption Reference Treasury Dealer Quotations"
means, with respect to each Optional Redemption Reference Treasury Dealer and
any Redemption Date for this Security, the average, as determined by the
Independent Investment Banker of the bid and asked prices for the Optional
Redemption Comparable Treasury Issue (expressed in each case as a percentage of
its principal amount) quoted in writing to the Independent Investment Banker and
the Trustee at 5:00 p.m., New York City time, on the third Business Day
preceding such Redemption Date.

                  5. Optional Redemption for Changes In Canadian Withholding
Taxes. The Securities will be subject to redemption in whole, but not in part,
at the Company's option and at any time, at a redemption price equal to 100% of
their principal amount, plus accrued and unpaid interest, if any, and Liquidated
Damages, if any, up to, but not including, the Redemption Date, in the event
that either the Company, the Guarantor or any other obligor under the
Securities, as the case may be, has become, or would become, obligated to pay,
on the next date on which any amount would be payable with respect to these
Securities, any Additional Amounts relating to any present or future Taxes, and
provided that the obligation to pay

                                      B-8
<PAGE>

Additional Amounts results from a change in the taxing laws and/or regulations
of Canada that is announced or becomes effective on or after the Issue Date;
provided, however; (1) no notice of redemption will be given earlier than 60
days prior to the earliest date on which the Company, the Guarantor or any other
obligor under the Securities, as the case may be, would be obligated to pay any
of these Additional Amounts if a payment with respect to this Security were then
due; (2) at the time any redemption notice is given, the obligation to pay these
Additional Amounts must remain in effect through the Redemption Date; and (3)
such obligation to pay Additional Amounts cannot be avoided by the Company by
taking reasonable measures available to it that it determines would not have an
adverse impact on it. Prior to any redemption of these Securities under these
provisions, the Company will deliver to the Trustee or any Paying Agent an
Officers' Certificate stating that the Company is entitled to effect the
redemption and setting forth a statement of facts showing that the conditions
precedent to the right of redemption have occurred.

                  6. Paying Agent and Registrar. Initially, The Chase Manhattan
Bank (the "Trustee"), the Trustee under the Indenture, will act as Paying Agent
and Registrar. The Company may change any Paying Agent, Registrar, co-registrar
or additional paying agent without notice to any Holder. The Guarantor or any of
its Subsidiaries may act in any such capacity.

                  7. Indenture. The Company issued this Security under an
Indenture dated as of October 3, 2001 (as amended, supplemented or otherwise
modified from time to time, the "Indenture") among the Company, Devon Energy
Corporation and the Trustee. The terms of this Security include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb), as in
effect on the date of execution of the Indenture. This Security and the
Guarantee are subject to all such terms, and Holders are referred to the
Indenture and such Act for a statement of such terms. Capitalized terms used but
not defined in this Security have the respective meanings given to such terms in
the Indenture.

                  8. Denominations, Transfer, Exchange. This Security is in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of this Security may be registered and this
Security may be exchanged as provided in the Indenture. The Registrar and the
Trustee may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar need not exchange or register
the transfer of this Security during the period between a record date and the
corresponding Interest Payment Date.

                  9. Persons Deemed Owners. The registered Holder of a Security
shall be treated as its owner for all purposes.

<PAGE>

                  10. Amendments and Waivers. Subject to certain exceptions and
limitations, the Indenture or this Security may be amended or supplemented with
the consent of the Holders of at least a majority in principal amount of the
then outstanding Securities, and compliance in a particular instance by the
Company or the Guarantor with any provision of the Indenture with respect to the
Securities may be waived (other than certain provisions, including any
continuing Default or Event of Default in the payment of the principal of or
premium, if any, Additional Amounts, if any, or interest on these Securities) by
the Holders of at least a majority in principal amount of the Securities then
outstanding in accordance with the terms of the Indenture. Without the consent
of any Holder, the Company, the Guarantor and the Trustee may amend or
supplement the Indenture or this Security to convey, transfer, assign, mortgage
or pledge to the Trustee as security for this Security any property or assets;
to evidence the succession of another entity to the Company or the Guarantor, or
successive successions, and the assumption by the successor entity of the
covenants, agreements and obligations of the Company or the Guarantor pursuant
to Section 4.01 or 4.02 of the Indenture; to add to the covenants of the Company
or the Guarantor such further covenants, restrictions, conditions or provisions
as the Company or the Guarantor and the Trustee shall consider to be for the
protection of the Holders of Securities of one or more series, to surrender any
right or power herein conferred upon the Company or the Guarantor, and to make
the occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions, conditions or provisions of an Event of
Default permitting the enforcement of all or any of the several remedies
provided in the Indenture, provided that in respect of any such additional
covenant, restriction, condition or provision such amendment or supplemental
indenture may provide for a particular period of grace after default (which
period may be shorter or longer than that allowed in the case of other defaults)
or may provide for an immediate enforcement upon such an Event of Default or may
limit the remedies available to the Trustee upon such an Event of Default or may
limit the right of the Holders of a majority in aggregate principal amount of
the Securities of such series to waive such an Event of Default; to cure any
ambiguity or to correct or supplement any provision contained in the Indenture
or in any supplemental indenture which may be defective or inconsistent with any
other provision contained in the Indenture or in any supplemental indenture,
provided that no such action shall adversely affect the interests of the Holders
of this Security; to evidence and provide for the acceptance of appointment
under the Indenture by a successor trustee with respect to the Securities of one
or more series and to add to or change any of the provisions of the Indenture as
shall be necessary to provide for or facilitate the administration of the trusts
under the Indenture by more than one trustee, pursuant to the requirements of
Section 6.08 or Section 6.09 of the Indenture; to provide for uncertificated
Securities in addition to or in place of certificated Securities; to comply with
any requirements, including the requirements of the SEC, in order to effect or
maintain the qualification of the Indenture under the TIA; to comply with the
rules or regulations of any securities exchange or automated quotations system
on which any of the Securities may be listed or traded; to make any change that
does not adversely affect the rights under the Indenture of any Holder; and to
effect the substitution of Devon HoldCo as the Parent under the Indenture and
the addition of Devon HoldCo as a "Guarantor" under the Indenture, in

                                      B-10
<PAGE>

each case as contemplated in connection with a Mitchell Restructuring Event
pursuant to Section 11.18 of the Indenture, and to make all such other
modifications as are necessary or desirable in light of such Mitchell
Restructuring Event to accomplish the transactions described in Section 11.18 of
the Indenture or as are not inconsistent with the Indenture and do not adversely
affect the rights of any Holder.

                  The right of any Holder to participate in any consent required
or sought pursuant to any provision of the Indenture (and the obligation of the
Company to obtain any such consent otherwise required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of this Security as of a date identified by the Trustee in a notice furnished to
Holders in accordance with the terms of the Indenture.

                  11. Defaults and Remedies. Events of Default include: (i)
default in the payment of the principal of or premium, if any, on any Security
at its Maturity; or (ii) default in the payment of interest, Liquidated Damages,
if any, or Additional Amounts, if any, upon any of the Securities when it
becomes due and payable, and continuance of such default for a period of 30
days; or (iii) default in the performance or observance, or breach, of any
covenant of the Company or the Guarantor in any Security or the Indenture (other
than a covenant a default in whose performance or whose breach is elsewhere in

default or breach for a period of 90 days after there has been given, by
registered or certified mail, to the Company and the Guarantor by the Trustee or

Debt of the Company or the Guarantor outstanding in an aggregate principal
amount in excess of $50,000,000 at the final stated maturity thereof or the

cause such Funded Debt to become, or to be declared, due prior to its final
stated maturity, and there has been given, by registered or certified mail, to
the Company and the Guarantor by the Trustee or to the Company, the Guarantor
and the Trustee by the Holders of at least 25% in aggregate principal amount of
the outstanding Securities a written notice specifying such default and
requiring it to be remedied and stating that such notice is a "Notice of
Default" hereunder unless (A) such default shall be cured, by payment or
otherwise, within 60 days after the receipt of such notice or (B) the
acceleration is not rescinded or annulled or the default that caused the
acceleration is not cured within 60 days after the receipt of such notice; or

<PAGE>

appointing a custodian, receiver, receiver and manager, interim receiver,

or Canadian Federal or State or provincial bankruptcy, insolvency,
reorganization or other similar law or to the commencement of any bankruptcy or
insolvency case or proceeding against either of them, or the filing by either of
them of a petition or answer or consent seeking reorganization or relief under
any applicable U.S. or Canadian Federal or State or provincial law, or the
consent by either of them to the filing of such petition or to the appointment

(viii) any Mitchell Restructuring Event is consummated as contemplated in
Section 11.18 of the Indenture and, thereafter, Devon HoldCo fails to become a
"Guarantor" under the Indenture in accordance with Section 11.18 of the
Indenture.

                  If an Event of Default (other than an Event of Default
specified in clause (5) or (6) of Section 5.01 of the Indenture) with respect to
this Security occurs and is continuing, the Trustee by notice to the Company and
the Guarantor, or by the Holders of at least 25% in aggregate principal amount
of the then outstanding Securities by written notice to the Company, the
Guarantor and the Trustee, may declare the principal of and Liquidated Damages,
if any, Additional Amounts, if any, and interest on all then outstanding
Securities to be due and payable immediately. The amount due and payable upon
the acceleration of any Security is equal to 100% of the principal amount
thereof plus Liquidated Damages, if any, Additional Amounts, if any, and accrued
interest to the date of payment. Holders may not enforce the Indenture or this
Security except as provided in the Indenture. The Trustee does require indemnity
reasonably satisfactory to it before it enforces the Indenture or this Security.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding Securities may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders notice of any continuing default
(except a default in payment of principal or

                                      B-12
<PAGE>

premium, if any, or interest) if it determines that withholding notice is in
their interests. The Company and the Guarantor each must furnish an annual
compliance certificate to the Trustee.

                  12. Additional Amounts. If the Company is required to withhold
or deduct any amount for or on account of any Taxes for any payment made under
or with respect to this Security, the Company will pay any Additional Amounts.

                  13. Discharge Prior to Maturity. The Indenture shall be
discharged and canceled upon the payment of all of the Securities and shall be
discharged except for certain obligations upon the irrevocable deposit with the
Trustee of cash, or U.S. Government Obligations or a combination thereof
sufficient for such payment.

                  14. Trustee Dealings with the Company and the Guarantor. The
Trustee in its individual or any other capacity may become the owner or pledgee
of this Security and may otherwise deal with the Company, the Parent or any of
their Affiliates with the same rights it would have if it were not the Trustee.

                  15. No Recourse Against Others. A director, officer, employee
or stockholder of the Company or the Guarantor, as such, shall not have any
liability for any obligations of the Company or the Guarantor under this
Security, the Guarantee or the Indenture or for any claim based on, in respect
of or by reason of such obligations or their creation. Each Holder by accepting
this Security waives and releases all such liability. The waiver and release are
part of the consideration for the issuance of this Security.

                  16. Authentication. This Security shall not be entitled to any
benefit under the Indenture or be valid or obligatory for any purpose until
authenticated by the manual signature of an authorized signatory of the Trustee,
which signature shall be conclusive evidence that this Security has been
authenticated under the Indenture.

                  17. CUSIP Numbers. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused a CUSIP number to be printed on this Security as a convenience to the
Holders of this Security. No representation is made as to the correctness of
such number either as printed on this Security or as contained in any notice of
a redemption and that reliance may be placed only on the other identification
numbers printed on this Security.

                  18. Abbreviations. Customary abbreviations may be used in the
name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT

survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
(= Uniform Gifts to Minors Act).

                  19. Governing Law. The Indenture, this Security and the
Guarantee shall be governed by and constructed in accordance with, the laws of
the State of New York. The

                                      B-13
<PAGE>

Company agrees to submit to the jurisdiction of the courts of the State of New
York in any action or proceeding relating to this Security and the Guarantee.

                  20. Additional Rights and Obligations of Holders. In addition
to the rights provided to Holders of Securities under the Indenture, this
Security and the Guarantee, Holders shall have all the rights set forth in the

         Section 2. Exchange Offer

         (a) The Issuers shall (i) file a Registration Statement (the "Exchange
Offer Registration Statement") within 75 days after the Issue Date with the
Commission on an appropriate registration form with respect to a registered
offer (the "Exchange Offer") to exchange any and all of the Registrable
Securities for a like aggregate principal amount of Securities (including the
guarantees with respect thereto, the "Exchange Securities") that are identical
in all material respects to the Securities (except that the Exchange Securities
shall not contain terms with respect to transfer restrictions or Liquidated
Damages upon a Registration Default), (ii) use their respective commercially
reasonable efforts to cause the Exchange Offer Registration Statement to be
declared effective under the Securities Act within 210 days after the Issue Date
and (iii) complete the Exchange Offer within 270 days after the Issue Date. Upon
the Exchange Offer Registration Statement being declared effective by the
Commission, the Issuers will offer the Exchange Securities in exchange for
surrender of the Securities. The Issuers shall keep the Exchange Offer open for
not less than 20 Business Days (or longer if required by applicable law) after
the date notice of the Exchange Offer is first mailed to Holders.

         Each Holder that participates in the Exchange Offer will be required to
represent to the Issuers in writing that (i) any Exchange Securities to be
received by it will be acquired in the ordinary course of its business, (ii) at
the time of the Exchange Offer, it has no

                                      -5-
<PAGE>

arrangement or understanding with any Person to participate in the distribution
(within the meaning of the Securities Act) of the Exchange Securities in
violation of the provisions of the Securities Act, (iii) it is not an affiliate
(as defined in Rule 405 under the Securities Act) of either Issuer, if it is an
affiliate, it will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable, (iv) if such Holder
is not a broker-dealer, it is not engaged in, and does not intend to engage in,
a distribution of Exchange Securities and (v) if such Holder is a broker-dealer
that will receive Exchange Securities for its own account in exchange for
Securities that were acquired as a result of market-making or other trading
activities, it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such Exchange Securities.

          (b) The Issuers and the Initial Purchasers acknowledge that the staff
of the Commission has taken the position that any broker-dealer that elects to
exchange Securities that were acquired by such broker-dealer for its own account
as a result of market-making or other trading activities for Exchange Securities
in the Exchange Offer (a "Participating Broker-Dealer") may be deemed to be an
"underwriter" within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Securities (other than a resale of an unsold allotment
resulting from the original offering of the Securities).

          The Issuers and the Initial Purchasers also acknowledge that the staff
of the Commission has taken the position that if the Prospectus contained in the
Exchange Offer Registration Statement includes a plan of distribution containing
a statement to the above effect and the means by which Participating
Broker-Dealers may resell the Exchange Securities, without naming the
Participating Broker-Dealers or specifying the amount of Exchange Securities
owned by them, such Prospectus may be delivered by Participating Broker-Dealers
to satisfy their prospectus delivery obligations under the Securities Act in
connection with resales of Exchange Securities for their own accounts, so long
as the Prospectus otherwise meets the requirements of the Securities Act.

          In light of the foregoing, if requested by a Participating
Broker-Dealer (a "Requesting Participating Broker-Dealer"), the Issuers agree to
use their respective commercially reasonable efforts to keep the Exchange Offer
Registration Statement continuously effective for a period of up to 180 days
after the date on which the Exchange Offer Registration Statement is declared
effective, or such longer period if extended pursuant to the last paragraph of
Section 5 hereof (such period, the "Applicable Period"), or such earlier date as
all Requesting Participating Broker-Dealers shall have notified the Issuers in
writing that such Requesting Participating Broker-Dealers have resold all
Exchange Securities acquired in the Exchange Offer. The Issuers shall include a
plan of distribution in such Exchange Offer Registration Statement that meets
the requirements set forth in the preceding paragraph.

                                      -6-
<PAGE>

          If, prior to consummation of the Exchange Offer, any Holder holds any
Securities acquired by it that have, or that are reasonably likely to be
determined to have, the status of an unsold allotment in an initial
distribution, or if any Holder is not entitled to participate in the Exchange
Offer, the Issuers upon the request of any such Holder shall simultaneously with
the delivery of the Exchange Securities in the Exchange Offer, issue and deliver
to any such Holder, in exchange (the "Private Exchange") for such Securities
held by any such Holder, a like principal amount of securities (the "Private
Exchange Securities") of the Issuers that are identical in all material respects
to the Exchange Securities, except for the placement of a restrictive legend on
such Private Exchange Securities. The Private Exchange Securities shall be
issued pursuant to the same indenture as the Exchange Securities and bear the
same CUSIP number as the Exchange Securities.

          In connection with the Exchange Offer, the Issuers shall:

          (1) mail or cause to be mailed to each Holder entitled to participate
     in the Exchange Offer a copy of the Prospectus forming part of the Exchange
     Offer Registration Statement, together with an appropriate letter of
     transmittal and related documents;

          (2) utilize the services of a depositary for the Exchange Offer with
     an address in the Borough of Manhattan, The City of New York;

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

          (4) otherwise comply in all material respects with all applicable
     laws, rules and regulations.

          As soon as practicable after the close of the Exchange Offer and the
Private Exchange, if any, the Issuers shall:

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

          (2) deliver or cause to be delivered to the Trustee for cancellation
     all Securities so accepted for exchange; and

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

                                      -7-
<PAGE>

          The Exchange Offer and the Private Exchange shall not be subject to
any conditions, other than that (i) the Exchange Offer or Private Exchange, as
the case may be, does not violate applicable law or any applicable
interpretation of the staff of the Commission, (ii) no action or proceeding
shall have been instituted or threatened in any court or by any governmental
agency which might materially impair the ability of the Issuers to proceed with
the Exchange Offer or the Private Exchange, and no material adverse development
shall have occurred in any existing action or proceeding with respect to the
Issuers and (iii) all governmental approvals shall have been obtained, which
approvals the Issuers deem necessary for the consummation of the Exchange Offer
or Private Exchange.

          The Exchange Securities and the Private Exchange Securities shall be
issued under (i) the Indenture or (ii) an indenture identical in all material
respects to the Indenture (in either case, with such changes as are necessary to
comply with any requirements of the Commission to effect or maintain the
qualification thereof under the TIA) and which, in either case, has been
qualified under the TIA and shall provide that the Exchange Securities shall not
be subject to the transfer restrictions set forth in the Indenture. The
Indenture or such other indenture shall provide that the Exchange Securities,
the Private Exchange Securities and the Securities shall vote and consent
together on all matters as one class and that none of the Exchange Securities,
the Private Exchange Securities or the Securities will have the right to vote or
consent as a separate class on any matter.

          (c) In the event that (i) applicable law or interpretations of the
staff of the Commission do not permit the Issuers to effect the Exchange Offer,
(ii) for any other reason the Exchange Offer is not completed within 270 days
after the Issue Date, (iii) at the request of any Holder (other than an Initial
Purchaser) who is prohibited by applicable law or interpretations of the staff
of the Commission from participating in the Exchange Offer, (iv) at the request
of any Initial Purchaser in the event that such Initial Purchaser (or any
affiliate thereof) participates in the Exchange Offer and does not receive
Exchange Securities on the date of the exchange that may be sold without
restriction under applicable law or interpretations of the staff of the
Commission (other than due solely to the status of such holder as an affiliate
of the Issuers), (v) the Initial Purchasers so request with respect to
Securities that have, or that are reasonably likely to be determined to have,
the status of unsold allotments in an initial distribution or (vi) any Holder of
Private Exchange Securities so requests (each such event referred to in clauses
(i) through (vi) of this sentence, a "Shelf Filing Event"), then the Issuers
shall file a Shelf Registration Statement pursuant to Section 3 hereof.

          Section 3. Shelf Registration Statement

          If at any time a Shelf Filing Event shall occur, then:

          (a) Shelf Registration Statement. The Issuers shall file with the
Commission a Registration Statement for an offering to be made on a continuous
basis pursuant to

                                      -8-
<PAGE>

Rule 415 covering all of the Registrable Securities not exchanged in the
Exchange Offer, Private Exchange Securities and Exchange Securities as to which
Section 2(c)(iv) is applicable (the "Initial Shelf Registration Statement"). The
Issuers shall file with the Commission the Initial Shelf Registration Statement
as promptly as practicable and in any event on or prior to 45 days after such
Shelf Filing Event occurs. The Initial Shelf Registration Statement shall be on
Form S-3 or another appropriate form permitting registration of such Registrable
Securities for resale by Holders in the manner or manners designated by them
(including, without limitation, one or more underwritten offerings). The Issuers
shall not permit any securities other than the Registrable Securities to be
included in the Initial Shelf Registration Statement or in any Subsequent Shelf
Registration Statement (as defined below).

          The Issuers shall use their respective commercially reasonable efforts
(x) to cause the Initial Shelf Registration Statement to be declared effective
under the Securities Act on or prior to the 150th day after such Shelf Filing
Event occurs and (y) to keep the Initial Shelf Registration Statement
continuously effective under the Securities Act for the period ending on the
date which is two years from the date it becomes effective (or one year if the
Initial Shelf Registration Statement is filed at the request of an Initial
Purchaser), subject to extension pursuant to the penultimate paragraph of
Section 5 hereof (the "Effectiveness Period"), or such shorter period ending
when (i) all Registrable Securities covered by the Initial Shelf Registration
Statement have been sold in the manner set forth and as contemplated in the
Initial Shelf Registration Statement or (ii) a Subsequent Shelf Registration
Statement covering all of the Registrable Securities covered by and not sold
under the Initial Shelf Registration Statement or an earlier Subsequent Shelf
Registration Statement has been declared effective under the Securities Act;
provided, however, that (i) the Effectiveness Period in respect of the Initial
Shelf Registration Statement shall be extended to the extent required to permit
dealers to comply with the applicable prospectus delivery requirements of Rule
174 under the Securities Act and as otherwise provided herein and (ii) the
Issuers may suspend the effectiveness of the Initial Shelf Registration
Statement by written notice to the Holders solely as a result of the filing of a
post-effective amendment to the Initial Shelf Registration Statement to
incorporate annual audited financial information with respect to the Issuers
where such post-effective amendment is not yet effective and needs to be
declared effective to permit holders to use the related Prospectus.

          (b) Subsequent Shelf Registration Statements. If the Initial Shelf
Registration Statement or any Subsequent Shelf Registration Statement ceases to
be effective for any reason at any time during the Effectiveness Period (other
than because of the sale of all of the securities registered thereunder), the
Issuers shall use their respective commercially reasonable efforts to obtain the
prompt withdrawal of any order suspending the effectiveness thereof, and in any
event shall as soon as practicable after such cessation amend the Initial Shelf
Registration Statement or such Subsequent Shelf Registration Statement, as the
case may be, in a manner to obtain the withdrawal of the order suspending the
effectiveness thereof, or file an

                                      -9-
<PAGE>

additional "shelf" Registration Statement pursuant to Rule 415 covering all of
the Registrable Securities covered by and not sold under the Initial Shelf
Registration Statement or such earlier Subsequent Shelf Registration Statement
(each, a "Subsequent Shelf Registration Statement"). If a Subsequent Shelf
Registration Statement is filed, the Issuers shall use their respective
commercially reasonable efforts to cause the Subsequent Shelf Registration
Statement to be declared effective under the Securities Act as soon as
practicable after such filing and to keep such Subsequent Shelf Registration
Statement continuously effective for a period equal to the number of days in the
Effectiveness Period less the aggregate number of days during which the Initial
Shelf Registration Statement and any Subsequent Shelf Registration Statement was
previously continuously effective. As used herein, the term "Shelf Registration
Statement" means the Initial Shelf Registration Statement and any Subsequent
Shelf Registration Statement.

          (c) Supplements and Amendments. The Issuers agree 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 for
such Shelf Registration Statement or by the Securities Act or rules and
regulations thereunder for shelf registration, or if reasonably requested by the
Holders of a majority in aggregate principal amount of the Registrable
Securities covered by such Registration Statement or by any underwriter of such
Registrable Securities.

          Section 4. Liquidated Damages

          (a) The Issuers and the Initial Purchasers agree that the Holders will
suffer damages if the Issuers fail to fulfill their obligations under Section 2
or Section 3 hereof and that it would not be feasible to ascertain the extent of
such damages with precision. Accordingly, the Issuers agree that if:

               (i) the Exchange Offer Registration Statement is not filed with
          the Commission on or prior to the 75th day following the Issue Date,
          or, if that day is not a Business Day, then the next day that is a
          Business Day,

               (ii) the Exchange Offer Registration Statement is not declared
          effective on or prior to the 210th day following the Issue Date, or,
          if that day is not a Business Day, then the next day that is a
          Business Day,

               (iii) the Exchange Offer is not completed on or prior to the
          270th day following the Issue Date, or, if that day is not a Business
          Day, then the next day that is a Business Day, or

               (iv) the Shelf Registration Statement is required to be filed but
          is not filed or declared effective within the time periods set forth
          herein or is declared effective

                                      -10-
<PAGE>

          but thereafter ceases to be effective or usable prior to the
          expiration of the Effectiveness Period, except if the Shelf
          Registration Statement ceases to be effective or usable as
          specifically permitted by the penultimate paragraph of Section 5
          hereof,

(each such event referred to in clauses (i) through (iv) a "Registration
Default"), their liquidated damages in the form of additional cash interest
("Liquidated Damages") will accrue on the affected Securities and the affected
Exchange Securities, as applicable. The rate of Liquidated Damages will be 0.25%
per annum for the first 90-day period immediately following the occurrence of a
Registration Default, increasing by an additional 0.25% per annum with respect
to the subsequent 90-day period up to a maximum amount of additional interest of
0.50% per annum, from and including the date on which any such Registration
Default shall occur to, but excluding, the earlier of (1) the date on which all
Registration Defaults have been cured or (2) the date on which all the
Securities and Exchange Securities otherwise become freely transferable by
Holders other than affiliates of the Issuers without further registration under
the Securities Act.

          Notwithstanding the foregoing, (1) the amount of Liquidated Damages
payable shall not increase because more than one Registration Default has
occurred and is pending and (2) a Holder of Securities or Exchange Securities
who is not entitled to the benefits of the Shelf Registration Statement (i.e.,
such Holder has not elected to include information) shall not be entitled to
Liquidated Damages with respect to a Registration Default that pertains to the
Shelf Registration Statement.

          (b) The Issuers shall notify the Trustee within one Business Day after
each and every date on which an event occurs in respect of which Liquidated
Damages are required to be paid (an "Event Date"). Any amounts of Liquidated
Damages due pursuant to this Section 4 will be payable in addition to any other
interest payable from time to time with respect to the Registrable Securities in
cash semi-annually on the interest payment dates specified in the Indenture (to
the applicable holders of record as specified in the Indenture), commencing with
the first such interest payment date occurring after any such Liquidated Damages
commence to accrue. The amount of Liquidated Damages will be determined in a
manner consistent with the calculation of interest under the Indenture.

          Section 5. Registration Procedures

          In connection with the filing of any Registration Statement pursuant
to Section 2 or 3 hereof, the Issuers shall effect such registrations to permit
the sale of the securities covered thereby in accordance with the intended
method or methods of disposition thereof, and pursuant thereto and in connection
with any Registration Statement filed by the Issuers hereunder, the Issuers
shall:

                                      -11-
<PAGE>

          (a) Prepare and file with the Commission the Registration Statement or
     Registration Statements prescribed by Section 2 or 3 hereof, and use their
     respective commercially reasonable efforts to cause each such Registration
     Statement to become effective and remain effective as provided herein;
     provided, however, that, if (1) such filing is pursuant to Section 3
     hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Securities during the Applicable Period relating thereto,
     before filing any Registration Statement or Prospectus or any amendments or
     supplements thereto, the Issuers shall furnish to and afford the Holders of
     the Registrable Securities covered by such Registration Statement or each
     such Participating Broker-Dealer, as the case may be, their counsel and the
     managing underwriters, if any, a reasonable opportunity to review copies of
     all such documents (including copies of any documents to be incorporated by
     reference therein and all exhibits thereto) proposed to be filed (in each
     case at least five Business Days prior to such filing). The Issuers shall
     not file any Registration Statement or Prospectus or any amendments or
     supplements thereto if the Holders of a majority in aggregate principal
     amount of the Registrable Securities covered by such Registration
     Statement, or any such Participating Broker-Dealer, as the case may be,
     their counsel, or the managing underwriters, if any, shall reasonably
     object.

          (b) Prepare and file with the Commission such amendments and
     post-effective amendments to each Initial Shelf Registration Statement or
     Exchange Offer Registration Statement, as the case may be, as may be
     necessary to keep such Registration Statement continuously effective for
     the Effectiveness Period or the Applicable Period, as the case may be;
     cause the related Prospectus to be supplemented by any Prospectus
     supplement required by applicable law, and as so supplemented to be filed
     pursuant to Rule 424 (or any similar provisions then in force) promulgated
     under the Securities Act; and comply with the provisions of the Securities
     Act and the Exchange Act with respect to the disposition of all securities
     covered by such Registration Statement as so amended or in such Prospectus
     as so supplemented and with respect to the subsequent resale of any
     securities being sold by a Participating Broker-Dealer covered by any such
     Prospectus, in each case, in accordance with the intended methods of
     distribution set forth in such Registration Statement or Prospectus, as so
     amended.

          (c) If (1) a Shelf Registration Statement is filed pursuant to Section
     3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Securities during the Applicable Period relating thereto,
     notify the selling Holders of Registrable Securities,

                                      -12-
<PAGE>

     or each such Participating Broker-Dealer, as the case may be, their counsel
     and the managing underwriters, if any, as promptly as possible, and, if
     requested by any such Person, confirm such notice in writing, (i) when a
     Prospectus or any Prospectus supplement or post-effective amendment has
     been filed, and, with respect to a Registration Statement or any
     post-effective amendment, when the same has become effective under the
     Securities Act (including in such notice a written statement that any
     Holder may, upon request, obtain, at the sole expense of the Issuers, one
     conformed copy of such Registration Statement or post-effective amendment
     including financial statements and schedules, documents incorporated or
     deemed to be incorporated by reference and exhibits), (ii) of the issuance
     by the Commission of any stop order suspending the effectiveness of a
     Registration Statement or of any order preventing or suspending the use of
     any preliminary prospectus or the initiation of any proceedings for that
     purpose, (iii) if at any time when a Prospectus is required by the
     Securities Act to be delivered in connection with sales of the Registrable
     Securities or resales of Exchange Securities by Participating
     Broker-Dealers, the representations and warranties of the Issuers contained
     in any agreement (including any underwriting agreement) contemplated by
     Section 5(m) hereof cease to be true and correct in all material respects,
     (iv) of the receipt by the Issuers of any notification with respect to the
     suspension of the qualification or exemption from qualification of a
     Registration Statement or any of the Registrable Securities or the Exchange
     Securities for offer or sale in any jurisdiction, or the initiation or
     threatening of any proceeding for such purpose, (v) of the happening of any
     event, the existence of any condition or any information becoming known to
     the Issuers that makes any statement made in such Registration Statement or
     related Prospectus or any document incorporated or deemed to be
     incorporated therein by reference untrue in any material respect or that
     requires the making of any changes in or amendments or supplements to such
     Registration Statement, Prospectus or documents so that, in the case of the
     Registration Statement, it will not contain any untrue statement of a
     material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein not misleading, and
     that in the case of the Prospectus, it will not contain any untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein or necessary to make the statements therein, in the light
     of the circumstances under which they were made, not misleading, and (vi)
     of the Issuers' determination that a post-effective amendment to a
     Registration Statement would be appropriate.

          (d) If (1) a Shelf Registration Statement is filed pursuant to Section
     3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Securities during the Applicable Period, use their respective
     commercially reasonable efforts to prevent the issuance of any order
     suspending the effectiveness of a Registration Statement or of

                                      -13-
<PAGE>

     any order preventing or suspending the use of a Prospectus or suspending
     the qualification (or exemption from qualification) of any of the
     Registrable Securities or the Exchange Securities, as the case may be, for
     sale in any jurisdiction, and, if any such order is issued, to use their
     respective commercial reasonable efforts to obtain the withdrawal of any
     such order at the earliest practicable moment.

          (e) If (1) a Shelf Registration Statement is filed pursuant to Section
     3 or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Securities during the Applicable Period and if requested by
     the managing underwriter or underwriters (if any), the Holders of a
     majority in aggregate principal amount of the Registrable Securities
     covered by such Registration Statement or any Participating Broker-Dealer,
     as the case may be, (i) promptly incorporate in such Registration Statement
     or Prospectus a prospectus supplement or post-effective amendment such
     information as the managing underwriter or underwriters (if any), such
     Holders or any Participating Broker-Dealer, as the case may be (based upon
     advice of counsel), determine is reasonably necessary to be included
     therein and (ii) make all required filings of such prospectus supplement or
     such post-effective amendment as soon as practicable after the Issuers have
     received notification of the matters to be incorporated in such prospectus
     supplement or post-effective amendment; provided, however, that the Issuers
     shall not be required to take any action hereunder that would, in the
     written opinion of counsel to the Issuers, violate applicable laws.

          (f) If (1) a Shelf Registration Statement is filed pursuant to Section
     3 hereof or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Securities during the Applicable Period, furnish to each
     selling Holder of Registrable Securities or each such Participating
     Broker-Dealer, as the case may be, who so requests, their counsel and each
     managing underwriter, if any, at the sole expense of the Issuers, one
     conformed copy of the Registration Statement or Registration Statements and
     each post-effective amendment thereto, including financial statements and
     schedules, and, if requested, all documents incorporated or deemed to be
     incorporated therein by reference and all exhibits.

          (g) If (1) a Shelf Registration Statement is filed pursuant to Section
     3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Securities during the Applicable Period, deliver to each
     selling Holder of Registrable Securities or each

                                      -14-
<PAGE>

     such Participating Broker-Dealer, as the case may be, their respective
     counsel, and the underwriters, if any, at the sole expense of the Issuers,
     as many copies of the Prospectus or Prospectuses (including each form of
     preliminary prospectus) and each amendment or supplement thereto and any
     documents incorporated by reference therein as such Persons may reasonably
     request; and, subject to the last paragraph of this Section 5, the Issuers
     hereby consent to the use of such Prospectus and each amendment or
     supplement thereto by each of the selling Holders of Registrable Securities
     or each such Participating Broker-Dealer, as the case may be, and the
     underwriters or agents, if any, and dealers (if any), in connection with
     the offering and sale of the Registrable Securities or the sale by
     Participating Broker-Dealers of the Exchange Securities.

          (h) Prior to any public offering of Registrable Securities or Exchange
     Securities or any delivery of a Prospectus contained in the Exchange Offer
     Registration Statement by any Participating Broker-Dealer who seeks to sell
     Exchange Securities during the Applicable Period, use commercially
     reasonable efforts to register or qualify, and to cooperate with the
     selling Holders of Registrable Securities or each such Participating
     Broker-Dealer, as the case may be, the managing underwriter or
     underwriters, if any, and their respective counsel in connection with the
     registration or qualification (or exemption from such registration or
     qualification) of such Registrable Securities or Exchange Securities, as
     the case may be, for offer and sale under the securities or Blue Sky laws
     of such jurisdictions within the United States or similar laws within
     Canada or any province thereof as any selling Holder, Participating
     Broker-Dealer, or the managing underwriter or underwriters reasonably
     request; provided, however, that where Exchange Securities or Registrable
     Securities are offered other than through an underwritten offering, the
     Issuers agree to cause the Issuers' counsel to perform Blue Sky
     investigations and file registrations and qualifications required to be
     filed pursuant to this Section 5(h), keep each such registration or
     qualification (or exemption therefrom) effective during the period such
     Registration Statement is required to be kept effective and do any and all
     other acts or things reasonably necessary or advisable to enable the
     disposition in such jurisdictions of such Exchange Securities or
     Registrable Securities covered by the applicable Registration Statement;
     provided, however, that the Issuers shall not be required to (A) qualify
     generally to do business in any jurisdiction where it is not then so
     qualified, (B) take any action that would subject it to general service of
     process in any such jurisdiction where it is not then so subject or (C)
     subject itself to taxation in excess of a nominal dollar amount in any such
     jurisdiction where it is not then so subject.

          (i) If a Shelf Registration Statement is filed pursuant to Section 3
     hereof, cooperate with the selling Holders of Registrable Securities and
     the managing underwriter or underwriters, if any, to facilitate the timely
     preparation and delivery of certificates representing Registrable
     Securities to be sold, which certificates shall not bear

                                      -15-
<PAGE>

     any restrictive legends and shall be in a form eligible for deposit with
     The Depository Trust Company; and enable such Registrable Securities to be
     in such denominations and registered in such names as the managing
     underwriter or underwriters, if any, or selling Holders may request at
     least two Business Days prior to any sale of such Registrable Securities or
     Exchange Securities.

          (j) Use their commercially reasonable efforts to cause the Registrable
     Securities or Exchange Securities covered by any Registration Statement to
     be registered with or approved by such other governmental agencies or
     authorities as may be reasonably necessary to enable the seller or sellers
     thereof or the underwriter or underwriters, if any, to consummate the
     disposition of such Registrable Securities or Exchange Securities, except
     as may be required solely as a consequence of the nature of such selling
     Holder's business, in which case the Issuers will cooperate in all
     reasonable respects with the filing of such Registration Statement and the
     granting of such approvals.

          (k) If (1) a Shelf Registration Statement is filed pursuant to Section
     3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Securities during the Applicable Period, upon the occurrence
     of any event contemplated by Section 5(c)(v) or 5(c)(vi) hereof, as
     promptly as practicable prepare and (subject to Section 5(a) and the
     penultimate paragraph of this Section 5) file with the Commission, at the
     sole expense of the Issuers, a supplement or post-effective amendment to
     the Registration Statement or a supplement to the related Prospectus or any
     document incorporated or deemed to be incorporated therein by reference, or
     file any other required document so that, as thereafter delivered to the
     purchasers of the Registrable Securities being sold thereunder or to the
     purchasers of the Exchange Securities to whom such Prospectus will be
     delivered by a Participating Broker-Dealer, any such Prospectus 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, in the light of the circumstances under which they were made, not
     misleading.

          (l) Prior to the effective date of the first Registration Statement
     relating to the Registrable Securities, (i) provide the Trustee with
     certificates for the Registrable Securities in a form eligible for deposit
     with The Depository Trust Company and (ii) provide a CUSIP number for the
     Registrable Securities.

          (m) In connection with any underwritten offering of Registrable
     Securities pursuant to a Shelf Registration Statement, enter into an
     underwriting agreement as is customary in underwritten offerings of debt
     securities similar to the Securities and take all such other actions as are
     reasonably requested by the managing underwriter or underwriters

                                      -16-
<PAGE>

     in order to expedite or facilitate the registration or the disposition of
     such Registrable Securities and, in such connection, (i) make such
     representations and warranties to, and covenants with, the underwriters
     with respect to the business of the Guarantor and its subsidiaries
     (including any acquired business, properties or entity, if applicable) and
     the Registration Statement, Prospectus and documents, if any, incorporated
     or deemed to be incorporated by reference therein, in each case, as are
     customarily made by issuers to underwriters in underwritten offerings of
     debt securities similar to the Securities, and confirm the same in writing
     if and when requested; (ii) use their commercially reasonable efforts to
     obtain the written opinions of counsel to the Issuers and written updates
     thereof in form, scope and substance reasonably satisfactory to the
     managing underwriter or underwriters, addressed to the underwriters
     covering the matters customarily covered in opinions requested in
     underwritten offerings and such other matters as may be reasonably
     requested by the managing underwriter or underwriters; (iii) use their
     commercially reasonable efforts to obtain "cold comfort" letters and
     updates thereof in form, scope and substance reasonably satisfactory to the
     managing underwriter or underwriters from the independent certified public
     accountants of the Issuers (and, if necessary, any other independent
     certified public accountants of any subsidiary of the Guarantor or of any
     business acquired by the Guarantor for which financial statements and
     financial data are, or are required to be, included or incorporated by
     reference in the Registration Statement), addressed to each of the
     underwriters, such letters to be in customary form and covering matters of
     the type customarily covered in "cold comfort" letters in connection with
     underwritten offerings; and (iv) if an underwriting agreement is entered
     into, the same shall contain indemnification provisions and procedures no
     less favorable than those set forth in Section 7 hereof (or such other
     provisions and procedures acceptable to Holders of a majority in aggregate
     principal amount of Registrable Securities covered by such Registration
     Statement and the managing underwriter or underwriters or agents) with
     respect to all parties to be indemnified pursuant to said Section. The
     above shall be done at each closing under such underwriting agreement, or
     as and to the extent required thereunder.

          (n) If (1) a Shelf Registration Statement is filed pursuant to Section
     3 hereof or (2) a Prospectus contained in the Exchange Offer Registration
     Statement filed pursuant to Section 2 hereof is required to be delivered
     under the Securities Act by any Participating Broker-Dealer who seeks to
     sell Exchange Securities during the Applicable Period, make available for
     inspection by any selling Holder of such Registrable Securities being sold
     or each such Participating Broker-Dealer, as the case may be, any
     underwriter participating in any such disposition of Registrable
     Securities, if any, and any attorney, accountant or other agent retained by
     any such selling Holder or each such Participating Broker-Dealer, as the
     case may be, or underwriter (collectively, the "Inspectors"), at the
     offices where normally kept, during reasonable business hours, all
     financial and other records, pertinent corporate documents and instruments

                                      -17-
<PAGE>

     of the Guarantor and its subsidiaries (collectively, the "Records") as
     shall be reasonably necessary to enable them to exercise any applicable due
     diligence responsibilities, and cause the officers, directors and employees
     of the Guarantor and its subsidiaries to supply all information reasonably
     requested by any such Inspector in connection with such Registration
     Statement and Prospectus. Each Inspector shall agree in writing that it
     will not disclose any records that the Issuers determine, in good faith, to
     be confidential and that it notifies the Inspectors in writing are
     confidential unless (i) the disclosure of such Records is necessary to
     avoid or correct a misstatement or omission in such Registration Statement
     or Prospectus, (ii) the release of such Records is ordered pursuant to a
     subpoena or other order from a court of competent jurisdiction, (iii)
     disclosure of such information is necessary or advisable in connection with
     any action, claim, suit or proceeding, directly or indirectly, involving or
     potentially involving such Inspector and arising out of, based upon,
     relating to, or involving this Agreement or the Purchase Agreement, or any
     transactions contemplated hereby or thereby or arising hereunder or
     thereunder, or (iv) the information in such Records has been made generally
     available to the public; provided, however, that such Inspector shall, in
     the case of clauses (ii) and (iii), to the extent reasonably possible, have
     previously promptly provided the Issuers an opportunity to obtain a
     protective order therefor, and, in the case of clauses (i) through (iv),
     take such actions as are reasonably necessary to protect the
     confidentiality of such information (if practicable) to the extent such
     action is otherwise not inconsistent with, an impairment of or in
     derogation of the rights and interests of the Holder or any Inspector.

          (o) Provide an indenture trustee for the Registrable Securities or the
     Exchange Securities, as the case may be, and cause the Indenture or the
     trust indenture provided for in Section 2(b) hereof to be qualified under
     the TIA not later than the effective date of the Exchange Offer or the
     first Registration Statement relating to the Registrable Securities; and in
     connection therewith, cooperate with the trustee under any such indenture
     and the Holders of the Registrable Securities or Exchange Securities, as
     applicable, to effect such changes to such indenture as may be required for
     such indenture to be so qualified in accordance with the terms of the TIA;
     and execute, and use commercially reasonable efforts to cause such trustee
     to execute, all documents as may be required to effect such changes, and
     all other forms and documents required to be filed with the Commission to
     enable such indenture to be so qualified in a timely manner.

          (p) Comply with all applicable rules and regulations of the Commission
     and make generally available to the Guarantor's and the Company's
     securityholders earnings statements satisfying the provisions of Section
     11(a) of the Securities Act, in accordance with Rule 158 thereunder (or any
     similar rule promulgated under the Securities Act) or otherwise.

                                      -18-
<PAGE>

          (q) Upon the request of a Holder, upon consummation of the Exchange
     Offer or a Private Exchange, use their commercially reasonable efforts to
     obtain an opinion of counsel to the Issuers, in a form customary for
     underwritten transactions, addressed to the Trustee for the benefit of all
     Holders of Registrable Securities participating in the Exchange Offer or
     the Private Exchange, as the case may be, that the Exchange Securities or
     Private Exchange Securities, as the case may be, and the related indenture
     constitute legal, valid and binding obligations of the Issuers, enforceable
     against the Issuers in accordance with its respective terms, subject to
     customary exceptions and qualifications.

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

          (s) Cooperate with each seller of Registrable Securities covered by
     any Registration Statement and each underwriter, if any, participating in
     the disposition of such Registrable Securities and their respective counsel
     in connection with any filings required to be made with the National
     Association of Securities Dealers, Inc. (the "NASD").

          (t) Use their commercially reasonable efforts to take all other steps
     necessary or advisable to effect the registration of the Exchange
     Securities and/or Registrable Securities covered by a Registration
     Statement contemplated hereby.

          The Issuers may require each seller of Registrable Securities or
Exchange Securities as to which any registration is being effected to furnish to
the Issuers such information regarding such seller and the distribution of such
Registrable Securities or Exchange Securities as the Issuers may, from time to
time, reasonably request. The Issuers may exclude from such registration the
Registrable Securities or Exchange Securities of any seller so long as such
seller fails to furnish such information within a reasonable time after
receiving such request. Each seller as to which any Shelf Registration Statement
is being effected agrees to furnish promptly to the Issuers all information
required to be disclosed in order to make any information previously furnished
to the Issuers by such seller not materially misleading.

          If any such Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Guarantor or the Company, then
such Holder shall have the right to require (i) the insertion therein of
language, in form and substance reasonably satisfactory to such Holder, to the
effect that the holding by such Holder of such securities is not

                                      -19-
<PAGE>

to be construed as a recommendation by such Holder of the investment quality of
the securities covered thereby and that such holding does not imply that such
Holder will assist in meeting any future financial requirements of the Issuers,
or (ii) in the event that such reference to such Holder by name or otherwise is
not required by the Securities Act or any similar federal statute then in force,
the deletion of the reference to such Holder in any amendment or supplement to
the Registration Statement filed or prepared subsequent to the time that such
reference ceases to be required.

          Each Holder of Registrable Securities and each Participating
Broker-Dealer agrees by acquisition of such Registrable Securities or Exchange
Securities that, upon actual receipt of any notice from the Issuers (x) of the
happening of any event of the kind described in Section 5(c)(ii), 5(c)(iv),
5(c)(v), or 5(c)(vi) hereof, or (y) that the Board of Directors of each of the
Guarantor and the Company (the "Boards of Directors") has resolved that the
Issuers have a bona fide business purpose for doing so, then the Issuers may
delay the filing or the effectiveness of the Exchange Offer Registration
Statement or the Shelf Registration Statement (if not then filed or effective,
as applicable) and shall not be required to maintain the effectiveness thereof
or amend or supplement the Exchange Offer Registration Statement or the Shelf
Registration Statement, in all cases, for a period (a "Delay Period") expiring
upon the earlier to occur of (i) in the case of the immediately preceding clause
(x), such Holder's or Participating Broker-Dealer's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 5(k) hereof or until
it is advised in writing (the "Advice") by the Issuers that the use of the
applicable Prospectus may be resumed, and has received copies of any amendments
or supplements thereto or (ii) in the case of the immediately preceding clause
(y), the date which is the earlier of (A) the date on which such business
purpose ceases to interfere with the Issuers' obligations to file or maintain
the effectiveness of any such Registration Statement pursuant to this Agreement
or (B) 60 days after the Issuers notify the Holders of such good faith
determination. In the case of any Delay Period, the Issuers shall use their
commercially reasonable efforts to cause the expiration of such Delay Period at
the earliest possible date; provided, there shall not be more than 60 days of
Delay Periods during any 12-month period with respect to clause (y) above. Each
of the Effectiveness Period and the Applicable Period, if applicable, shall be
extended by the number of days during any Delay Period. Any Delay Period will
not alter the obligations of the Issuers to pay Liquidated Damages under the
circumstances set forth in Section 4 hereof.

          In the event of any Delay Period pursuant to clause (y) of the
preceding paragraph, notice shall be given as soon as practicable after the
Boards of Directors make such a determination of the need for a Delay Period and
shall state, to the extent practicable, an estimate of the duration of such
Delay Period and shall advise the recipient thereof of the agreement of such
Holder provided in the next succeeding sentence. Each Holder, by his acceptance
of any Registrable Security, agrees that during any Delay Period, each Holder
will discontinue disposition of such Securities or Exchange Securities covered
by such Registration

                                      -20-

Statement or Prospectus or Exchange Securities to be sold by such Holder or
Participating Broker-Dealer, as the case may be.

          Section 6. Registration Expenses

          All fees and expenses incident to the performance of or compliance
with this Agreement by the Issuers shall be borne by the Issuers, whether or not

case may be, (iii) messenger, telephone and delivery expenses, (iv) fees and

and any other documents necessary in order to comply with this

                                      -21-

Agreement. Notwithstanding the foregoing or anything to the contrary, each
Holder shall pay all underwriting discounts and commissions of any underwriters
with respect to any Registrable Securities sold by or on behalf of it.

          Section 7. Indemnification

          (a) The Issuers, jointly and severally, agree to indemnify and hold
harmless each Holder of Registrable Securities and each Participating
Broker-Dealer selling Exchange Securities during the Applicable Period, each
Person, if any, who controls any such Person within the meaning of Section 15 of
the Securities Act or Section 20(a) of the Exchange Act, the agents, employees,
officers and directors of each Holder and each such Participating Broker-Dealer
and the agents, employees, officers and directors of any such controlling Person

reasonable attorneys' fees and any and all reasonable expenses whatsoever
incurred in investigating, preparing or defending against any litigation,
commenced or threatened, or any claim whatsoever, and any and all reasonable
amounts paid in settlement of any claim or litigation) (collectively, "Losses")
to which they or any of them may become subject under the Securities Act, the
Exchange Act or otherwise insofar as such Losses (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement

circumstances under which they were made, not misleading, provided that the
foregoing indemnity shall not be available to any Participant insofar as such
Losses are caused by any untrue statement or omission or alleged untrue
statement or omission made in reliance upon and in conformity with information
relating to such Participant furnished to the Issuers in writing by or on behalf
of such Participant expressly for use therein. This indemnity agreement will be
in addition to any liability that the Issuer may otherwise have, including, but
not limited to, liability under this Agreement.

          (b) Each Participant agrees, severally and not jointly, to indemnify
and hold harmless each Issuer, each Person, if any, who controls either Issuer

or caused by, arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in the case of the Prospectus, in the light of the
circumstances under which they were made, not misleading, in each case to the
extent, but only to the extent, that any such Loss arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged
omission made in reliance upon and in conformity with information relating to
such Participant furnished in writing to the Issuers by or on behalf of such
Participant expressly for use therein.

          (c) Promptly after receipt by an indemnified party under subsection
7(a) or 7(b) above of notice of the commencement of any action, suit or
proceeding (collectively, an "action"), such indemnified party shall, if a claim
in respect thereof is to be made against the indemnifying party under such
subsection, notify each party against whom indemnification is to be sought in
writing of the commencement of such action (but the failure so to notify an
indemnifying party shall not relieve such indemnifying party from any liability
that it may have under this Section 7 except to the extent that it has been
prejudiced in any material respect by such failure). In case any such action is
brought against any indemnified party, and it notifies an indemnifying party of
the commencement of such action, the indemnifying party will be entitled to
participate in such action, and to the extent it may elect by written notice
delivered to the indemnified party promptly after receiving the aforesaid notice
from such indemnified party, to assume the defense of such action with counsel
satisfactory to such indemnified party. Notwithstanding the foregoing, the
indemnified party or parties shall have the right to employ its or their own
counsel in any such action, but the reasonable fees and expenses of such counsel
shall be at the expense of such indemnified party or parties unless (i) the
employment of such counsel shall have been authorized in writing by the
indemnifying parties in connection with the defense of such action, (ii) the
indemnifying parties shall not have employed counsel to take charge of the
defense of such action within a reasonable time after notice of commencement of
the action, or (iii) the named parties to such action (including any impleaded
parties) include such indemnified party and the indemnifying party or parties
(or such indemnifying parties have assumed the defense of such action), and such
indemnified party or parties shall have reasonably concluded that there may be
defenses available to it or them that are different from or additional to those
available to one or all of the indemnifying parties (in which case the
indemnifying parties shall not have the right to direct the defense of such
action on behalf of the indemnified party or parties), in any of which events
such reasonable fees and expenses of counsel shall be borne by the indemnifying
parties. In no event shall the indemnifying party be liable for the fees and
expenses of more than one counsel (together with appropriate local counsel)
designated by the indemnified party or parties at any time for all indemnified
parties in connection with any one action or separate but substantially similar
or related actions arising in the same jurisdiction out of the same general
allegations or circumstances. An indemnifying party shall not be liable for any
settlement of any claim or action effected without its written consent, which
consent may not be unreasonably

                                      -23-
<PAGE>

withheld. Notwithstanding the foregoing sentence, if at any time an indemnified
party shall have requested an indemnifying party to reimburse the indemnified
party for fees and expenses of counsel as contemplated by paragraph (a) or (b)
of this Section 7, then the indemnifying party agrees that it shall be liable
for any settlement of any proceeding effected without its written consent if (i)
such settlement is entered into more than 60 business days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
not have reimbursed the indemnified party in accordance with such request prior
to the date of such settlement and (iii) such indemnified party shall have given
the indemnifying party at least 30 days' prior notice of its intention to
settle. No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened proceeding
in respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party from
all liability on claims that are the subject matter of such proceeding.

          (d) In order to provide for contribution in circumstances in which the
indemnification provided for in this Section 7 is for any reason held to be
unavailable from the indemnifying party, or is insufficient to hold harmless a
party indemnified under this Section 7, each indemnifying party shall contribute
to the amount paid or payable by such indemnified party as a result of such
aggregate Losses (i) in such proportion as is appropriate to reflect the
relative benefits received by each indemnifying party, on the one hand, and each
indemnified party, on the other hand, from the sale of the Securities to the
Initial Purchasers or the resale of the Registrable Securities by such Holder,
as applicable, or (ii) if such allocation is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to above but also the relative fault of each indemnified party, on the
one hand, and each indemnifying party, on the other hand, in connection with the
statements or omissions that resulted in such Losses, as well as any other
relevant equitable considerations. The relative benefits received by the
Issuers, on the one hand, and each Participant, on the other hand, shall be
deemed to be in the same proportion as (x) the total proceeds from the sale of
the Securities to the Initial Purchasers (net of discounts and commissions but
before deducting expenses) received by the Issuer are to (y) the total net
proceeds received by such Participant in connection with the sale of the
Registrable Securities. The relative fault of the parties shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Issuers or such Participant and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission or alleged statement or omission.

          (e) The parties agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
or by any other method of allocation that does not take into account the
equitable considerations referred to above.

                                      -24-
<PAGE>

Notwithstanding the provisions of this Section 7, (i) in no case shall any
Participant be required to contribute any amount in excess of the amount by
which the net proceeds received by such Participant in connection with the sale
of the Registrable Securities exceeds the amount of any damages that such
Participant has otherwise been required to pay by reason of any untrue or
alleged untrue statement or omission or alleged omission and (ii) no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. For purposes of this Section 7, each Person,
if any, who controls any Participant within the meaning of Section 15 of the Act
or Section 20(a) of the Exchange Act and each director, officer, employee and
agent of such Participant shall have the same rights to contribution as such
Participant, and each Person, if any, who controls either Issuer within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and each
director, officer, employee and agent of either Issuer shall have the same
rights to contribution as such Issuer. Any party entitled to contribution will,
promptly after receipt of notice of commencement of any action against such
party in respect of which a claim for contribution may be made against another
party or parties under this Section 7, notify such party or parties from whom
contribution may be sought, but the omission to so notify such party or parties
shall not relieve the party or parties from whom contribution may be sought from
any obligation it or they may have under this Section 7 or otherwise, except to
the extent that it has been prejudiced in any material respect by such failure;
provided, however, that no additional notice shall be required with respect to
any action for which notice has been given under this Section 7 for purposes of
indemnification. Anything in this section to the contrary notwithstanding, no
party shall be liable for contribution with respect to any action or claim
settled without its written consent; provided, however, that such written
consent was not unreasonably withheld.

          Section 8. Rules 144 and 144A

          The Issuers covenant that they will file the reports required to be
filed by them under the Securities Act and the Exchange Act in accordance with
Section 3.03 of the Indenture and the rules and regulations adopted by the
Commission thereunder in a timely manner in accordance with the requirements of
the Securities Act and the Exchange Act and, if at any time either Issuer is not
required to file such reports, it will, upon the request of any Holder or
beneficial owner of Registrable Securities, make available such information
necessary to permit sales pursuant to Rule 144A under the Securities Act. The
Issuers further covenant that they will take such further action as any Holder
of Registrable Securities may reasonably request from time to time to enable
such Holder to sell Registrable Securities without registration under the
Securities Act within the limitation of the exemptions provided by (a) Rule
144(k) and Rule 144A under the Securities Act, as such Rules may be amended from
time to time, or (b) any similar rule or regulation hereafter adopted by the
Commission.

          Section 9. Underwritten Registrations

          If any of the Registrable Securities covered by any Shelf Registration
Statement are to be sold in an underwritten offering, the investment banker or
investment bankers and manager or managers that will manage the offering will be
selected by the Holders of a majority in aggregate principal amount of such
Registrable Securities included in such offering and shall be reasonably
acceptable to the Issuers.

          No Holder of Registrable Securities may participate in any
underwritten registration hereunder if such Holder does not (a) agree 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 (b) complete and execute all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements.

          Section 10. Miscellaneous

          (a) No Inconsistent Agreements. The Issuers have not entered, as of
the date hereof, and shall not enter, after the date of this Agreement, into any
agreement with respect to any of its securities that is inconsistent with the
rights granted to the Holders of Registrable Securities in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not conflict with and are not inconsistent with, in any
material respect, the rights granted to the holders of any of the Issuers' other
issued and outstanding securities under any such agreements. The Issuers have
not entered and will not enter into any agreement with respect to any of their
securities which will grant to any Person piggy-back registration rights with
respect to any Registration Statement.

          (b) Adjustments Affecting Registrable Securities. The Issuers shall
not, directly or indirectly, take any action with respect to the Registrable
Securities as a class that would adversely affect the ability of the Holders of
Registrable Securities to include such Registrable Securities in a registration
undertaken pursuant to this Agreement.

          (c) Amendments and Waivers. The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given except pursuant to a written agreement
duly signed and delivered by (I) the Issuers and (II)(A) the Holders of not less
than a majority in aggregate principal amount of the then outstanding
Registrable Securities and (B) in circumstances that would adversely affect the
Participating Broker-Dealers, the Participating Broker-Dealers holding not less
than a majority in aggregate principal amount of the Exchange Securities held by
all Participating Broker-Dealers; provided, however, that Section 7 and this
Section 10(c) may not be amended, modified or supplemented except pursuant to a
written agreement duly signed and delivered by each Holder and each
Participating Broker-Dealer (including any Person who

                                      -26-
<PAGE>

was a Holder or Participating Broker-Dealer of Registrable Securities or
Exchange Securities, as the case may be, disposed of pursuant to any
Registration Statement) affected by any such amendment, modification, supplement
or waiver. Notwithstanding the foregoing, a waiver or consent to depart from the
provisions hereof with respect to a matter that relates exclusively to the
rights of Holders of Registrable Securities whose securities are being sold
pursuant to a Registration Statement and that does not directly or indirectly
affect, impair, limit or compromise the rights of other Holders of Registrable
Securities may be given by Holders of at least a majority in aggregate principal
amount of the Registrable Securities being sold pursuant to such Registration
Statement. Each Holder at the time or thereafter outstanding shall be bound by
any amendment or waiver effected pursuant to this Section 10(c), whether or not
any notice, writing or marking indicating such amendment or waiver appears on
such Registrable Securities, Private Exchange Securities or Exchange Securities
or is delivered to such Holder.

          (d) Notices. All notices and other communications (including, without
limitation, any notices or other communications to the Trustee) provided for or
permitted hereunder shall be made in writing by hand-delivery, registered

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

          (e) Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of each of the parties hereto,
the Holders and the Participating Broker-Dealers; provided, however, that this
Agreement shall not inure to the benefit of or be binding upon a successor or
assign of a Holder unless and to the extent such successor or assign holds
Registrable Securities; and provided, further, that nothing herein shall be
deemed to permit any transfer of Registrable Securities in violation of this
Agreement, the Indenture or applicable law. In the event that any transferee of
any Holder 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 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 Agreement. If

                                      -28-

agree in writing to acquire and hold the Registrable Securities subject to all
of the applicable terms hereof.

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

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

          (h) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS
MADE AND PERFORMED WHOLLY WITHIN THE STATE OF NEW YORK.

          (i) Consent to Jurisdiction; Appointment of Agent to Accept Service of
Process.

          (I) The Company irrevocably consents and agrees that any legal action,
     suit or proceeding against it with respect to its obligations, liabilities
     or any other matter arising out of or in connection with this Agreement or
     the Securities may be brought in the courts of the State of New York, or
     the courts of the United States of America in each case located in the
     Borough of Manhattan in The City and State of New York and, until all
     amounts due and to become due in respect of the Securities have been paid,
     or until any such legal action, suit or proceeding commenced prior to such
     payment has been concluded, hereby irrevocably consents and submits to the
     non-exclusive jurisdiction of each such court in person, generally and for
     itself and in respect of its properties, assets and revenues.

          (II) The Company hereby irrevocably designates, appoints, and empowers
     Corporation Service Company, 80 State Street, Albany, NY 12207-2543, as its
     designee, appointee and agent to receive, accept and acknowledge for and on
     its behalf service of any and all legal process, summons, notices and
     documents that may be served in any action, suit or proceeding brought
     against the Company in any such United States federal or state court with
     respect to its obligations, liabilities or any other matter arising out of
     or in connection with this Agreement, the Indenture or the Securities and
     that may be made on such designee, appointee and agent in accordance with
     legal procedures prescribed for such courts. If for any reason such
     designee, appointee and agent hereunder shall cease to be available to act
     as such, the Company agrees to designate a new designee, appointee and
     agent in The City of New York on the terms and for the purposes of this
     Section 10(i) reasonably satisfactory to each of

                                      -29-
<PAGE>

     the Initial Purchasers. The Company further hereby irrevocably consents and
     agrees to the service of any and all legal process, summons, notices and
     documents in any such action, suit or proceeding against the Company by
     serving a copy thereof upon the relevant agent for service of process
     referred to in this Section 10(i) (whether or not the appointment of such
     agent shall for any reason prove to be ineffective or such agent shall
     accept or acknowledge such service) or by mailing copies thereof by
     registered or certified air mail, postage prepaid, to the Company at its
     address specified in or designated pursuant to this Agreement, with a copy
     (similarly mailed) to Corporation Service Company, 80 State Street, Albany,
     NY 12207-2543. The Company agrees that the failure of any such designee,
     appointee and agent to give any notice of such service to it shall not
     impair or affect in any way the validity of such service or any judgment
     rendered in any action or proceeding based thereon. Nothing herein shall in
     any way be deemed to limit the ability of the holders of the Securities or
     the Initial Purchasers to serve any such legal process, summons, notices
     and documents in any other manner permitted by applicable law or to obtain
     jurisdiction over the Company or bring actions, suits or proceedings
     against the Company in such other jurisdictions, and in such manner, as may
     be permitted by applicable law. The Company hereby irrevocably and
     unconditionally waives, to the fullest extent permitted by law, any
     objection that it may now or hereafter have to the laying of venue of any
     of the aforesaid actions, suits or proceedings arising out of or in
     connection with this Agreement brought in the United States federal courts
     located in the Borough of Manhattan in The City of New York or the courts
     of the State of New York located in the Borough of Manhattan in The City
     and State of New York and hereby further irrevocably and unconditionally
     waives and agrees not to plead or claim in any such court that any such
     action, suit or proceeding brought in any such court has been brought in an
     inconvenient forum.

          (III) The provisions of this Section 10(i) shall survive any
     termination of this Agreement, in whole or in part.

          (j) Severability. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their commercially reasonable efforts to find and employ an
alternative means to achieve the same or substantially the same result as that
contemplated by such term, provision, covenant or restriction. It is hereby
stipulated and declared to be the intention of the parties that they would have
executed the remaining terms, provisions, covenants and restrictions without
including any of such that may be hereafter declared invalid, illegal, void or
unenforceable.

                                      -30-

          (k) Securities Held by the Issuers or Their Affiliates. Whenever the
consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Issuers or
any of their respective affiliates (as such term is defined in Rule 405 under
the Securities Act) shall not be counted in determining whether such consent or
approval was given by the Holders of such required percentage.

          (l) Joint and Several Obligations of the Guarantor and the Company.
The obligations of the Guarantor and the Company under this Agreement are joint
and several.

          (m) Third-Party Beneficiaries. Holders and beneficial owners of
Registrable Securities and Participating Broker-Dealers are intended third-party
beneficiaries of this Agreement, and this Agreement may be enforced by such
Persons. No other Person is intended to be, or shall be construed as, a
third-party beneficiary of this Agreement.

          (n) Attorneys' Fees. As between the parties to this Agreement, in any
action or proceeding brought to enforce any provision of this Agreement, or
where any provision hereof is validly asserted as a defense, the successful
party shall be entitled to recover reasonable attorneys' fees actually incurred
in addition to its costs and expenses and any other available remedy.

          (o) Entire Agreement. This Agreement, together with the Purchase
Agreement and the Indenture, is intended by the parties as a final and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein and therein and any and all prior oral or
written agreements, representations, or warranties, contracts, understandings,
correspondence, conversations and memoranda between the Holders on the one hand
and the Issuer on the other, or between or among any agents, representatives,
parents, subsidiaries, affiliates, predecessors in interest or successors in
interest with respect to the subject matter hereof and thereof are merged herein
and replaced hereby.
