                  INDENTURE, dated as of September 14, 1999, among
Louisiana-Pacific Acquisition Inc. a corporation duly incorporated under Part 1A
of the COMPANIES ACT (Quebec) (the "Company"), Louisiana-Pacific Corporation, a
corporation duly organized and existing under the laws of the State of Delaware
(the "Guarantor") and Laurentian Trust of Canada Inc., a trust Company duly
organized and existing under the laws of Quebec (herein called the "Trustee").


                    RECITALS OF THE COMPANY AND THE GUARANTOR

         A. The Company and the Guarantor have duly authorized the execution and
delivery of this Indenture to provide for the issuance of the Company's
installment notes, to be issued in accordance with the terms of this Indenture.

         B. The Company and the Trustee have agreed that the Company shall issue
and deliver, and the Trustee shall authenticate, notes denominated "Senior
Installment Notes" (the "Securities") pursuant to the terms of this Indenture
and substantially in the form set forth below, in each case with such
appropriate insertions, omissions, substitutions, and other variations as are
required or permitted by this Indenture, and with such letters, numbers, or
other marks of identification and such legends or endorsements placed thereon as
may be required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Securities,
as evidenced by their execution of such Securities.

                           [FORM OF FACE OF SECURITY]

                       LOUISIANA-PACIFIC ACQUISITION INC.

                            Senior Installment Notes

No. __________                                                C$_______________

                  Louisiana-Pacific Acquisition Inc., a corporation duly
incorporated under Part 1A of the COMPANIES ACT (Quebec) (hereinafter called the
"Company," which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
________________________, or registered assigns, the principal sum of
C$_____________________________________, and to pay interest on the currently
outstanding principal amount from ________________ or, if later, from the most
recent Interest Payment Date to which interest on the debt evidenced hereby has
been paid or duly provided for, on September 30, December 31, March 31, and June
30 in each year, commencing December 31, 1999, at a rate per annum determined by
the Company to be equal to the Canadian LIBOR Rate plus the Margin (as such
terms are defined on the reverse side hereof), until the principal hereof is
paid or made available for payment. The interest so payable, and punctually paid
or duly provided for, on any Interest Payment Date will, as provided in such
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest, which will be the fifteenth calendar day (whether
or not a Business Day) next preceding such Interest Payment Date. Any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the




<PAGE>



Holder on such Regular Record Date and may either be paid to the Person in whose
name this Security (or one or more Predecessor Securities) is registered at the
close of business on a Special Record Date for the payment of such Defaulted
Interest to be fixed by the Trustee, notice whereof will be given to Holders of
the Securities not less than 10 calendar days prior to such Special Record Date,
or be paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Securities may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture.

         The principal will be paid in equal installments (each such payment, a
"Principal Installment") on [____________, 2000, ____________, 2001,
____________, 2002 and ____________, 2003] (each such date, a "Maturity Date").
To receive payment of a Principal Installment, the Holder of this Security must
surrender the same at the office or agency of the Company referred to below,
whereupon the Company will execute, and the Trustee will authenticate and
deliver to such Holder, without charge, a new Security or Securities of like
tenor, of any authorized denomination as requested by such Holder, in an
aggregate principal amount equal to and in exchange for the unpaid principal of
this Security. From and after the applicable Maturity Date, no interest will
accrue on the Principal Installment due on such Maturity Date. Payment of each
Principal Installment of this Security will be made on the applicable Maturity
Date or, if later, promptly after this Security is surrendered for such purpose
as described above.

         Payment of the Principal Installments and interest on this Security
will be made at the office or agency of the Company maintained for the purpose
in Montreal, Quebec, in such coin or currency of Canada as at the time of
payment is legal tender for payment of public and private debts; PROVIDED,
HOWEVER, that at the option of the Company payment of any Principal Installment
or interest may be made by check mailed to the address of the Person entitled
thereto as such address appears in the Security Register.

                  REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS SET FORTH
ON THE REVERSE HEREOF. SUCH PROVISIONS WILL FOR ALL PURPOSES HAVE THE SAME
EFFECT AS THOUGH FULLY SET FORTH IN THIS PLACE.

                  This Security will not be valid or become obligatory for any
purpose until the certificate of authentication on this Security has been signed
manually by the Trustee under the Indenture referred to on the reverse side
hereof.

apply to any suit instituted by the Holder of this Security for the enforcement
of any payment of principal hereof or interest hereon on or after the respective
due dates expressed herein.

which is absolute and unconditional, to pay the principal of and interest on
this Security at the times, place, and rate, and in the coin or currency, herein
prescribed.

of the Securities of like tenor of a different authorized denomination, as
requested by the Holder surrendering the same.

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

                  Prior to due presentment of this Security for registration of
transfer, the Company, the Guarantor, the Trustee, and any agent of the Company
or the Trustee may treat the Person in whose name this Security is registered as
the owner hereof for all purposes, whether or not this Security shall be

                           ARTICLE II. THE SECURITIES

SECTION 2.01.       DESIGNATION OF SECURITIES; PRINCIPAL AMOUNT; MATURITY

                    (a) The Securities are designated Senior Installment Notes.
The Securities will be unsecured obligations of the Company and will rank PARI
PASSU in right of payment with all other unsecured and unsubordinated
indebtedness of the Company.

                    (b) The Company will issue the Securities in conjunction
with its acquisition of all of the issued and outstanding Class A Multiple
Voting Shares and Class B Subordinate Voting Shares (collectively, the "Shares")
of Le Groupe Forex Inc. ("Forex") pursuant to the Company's offer to purchase
the Shares and any subsequent acquisition transaction that the Company may elect
to pursue (collectively, the "Acquisition"). Pursuant to the Acquisition, the
shareholders of Forex will be entitled to elect to receive (i) cash, or (ii) a
combination of cash and Securities. The Securities will be issued in an
aggregate principal amount equal to the aggregate amount of consideration
payable to holders of Shares in the form of Securities in connection with or by
reason of the Acquisition.

                    (c) The principal of the Securities will be paid in equal
installments (each a "Principal Installment") on September 30, 2000, September
30, 2001, September 30, 2002, and September 30, 2003 (each such date a "Maturity
Date"); provided, in the case of any particular Security, that such date is
later than the date of issuance of such Security. The principal of any Security
issued on or after a particular Maturity Date will be paid in equal installments
on the following Maturity Dates (or, in the case of any Security issued on or
after September 30, 2002, will be paid in full on September 30, 2003). To
receive payment of a Principal Installment, the Holder of a Security must
surrender the same at the office or agency of the Company designated for such
purpose pursuant to Section 4.02, whereupon the Company will execute, and the
Trustee will authenticate and deliver to such Holder, without charge, a new
Security or Securities of like tenor, of any authorized denomination as
requested by such Holder, in an aggregate principal amount equal to and in
exchange for the unpaid principal of the Security so surrendered. From and after
the applicable Maturity Date, no interest will accrue on the Principal
Installment due on such Maturity Date. Payment of each Principal Installment of
a Security will be made on the applicable Maturity Date or, if later, promptly
after a Security is surrendered for such purpose as described above.

                    (d) The Company shall issue and deliver to the Trustee, and
the Trustee shall authenticate, Securities substantially in the form set forth
above, in each case with such appropriate insertions, omissions, substitutions,
and other variations as are required or permitted by this Indenture, and with
such letters, numbers, or other marks of identification and such legends or
endorsements placed thereon as may, consistently herewith, be determined by the
officers executing such Securities, as evidenced by their execution of such
Securities.

SECTION 2.02.       FORM OF SECURITIES AND TRUSTEE'S CERTIFICATE OF
                    AUTHENTICATION

                    (a) The Securities will be in substantially the form set
forth in or otherwise contemplated by the recitals to this Indenture.


                                       15

<PAGE>



                    (b) The definitive Securities will be printed, lithographed,
or engraved on steel engraved borders or may be produced in any other manner as
determined by the officers executing such Securities, as evidenced by their
execution of such Securities.

                    (c) The Trustee's certificate of authentication will be in
substantially the form set forth in the recitals to this Indenture.

SECTION 2.03.       DATE AND DENOMINATIONS

                    Each Security will be issuable only in registered form
without coupons and will be dated the date of its authentication. Prior to the
first Maturity Date, the Securities will be issuable only in denominations of
C$1,000 and integral multiples thereof. From and after the first, second and
third Maturity Dates, the Securities will be issuable only in denominations of
C$750, C$500 and C$250, respectively, and integral multiples thereof.

SECTION 2.04.       EXECUTION, AUTHENTICATION AND DELIVERY OF SECURITIES

                    (a) The Securities will be executed on behalf of the Company
by the President, or any Vice President of the Company and attested by the
Treasurer, the Secretary, any Assistant Treasurer, or any Assistant Secretary of
the Company. The signature of any of these officers on the Securities may be
manual or facsimile.

                    (b) Only such Securities bearing the Trustee's certificate
of authentication, signed manually by the Trustee, will be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose. Such
execution of the certificate of authentication by the Trustee upon any
Securities executed by the Company will be conclusive evidence that the
Securities so authenticated have been duly authenticated and delivered
hereunder. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 2.08, for all purposes of this Indenture such Security will
be deemed never to have been authenticated and delivered hereunder and will
never be entitled to the benefits of this Indenture.

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

                    (d) At any time and from time to time after the execution
and delivery of this Indenture, the Company may deliver Securities executed by
the Company to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Securities, and the Trustee will
authenticate and deliver such Securities in accordance with such Company Order.

<PAGE>



SECTION 2.05.       REGISTRATION OF TRANSFER AND EXCHANGE

                    (a) The Company will cause to be kept at the Corporate Trust
Office a register (the register maintained in such office and in any other
office or agency of the Company designated pursuant to Section 4.02 being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company will provide for
the registration of Securities and of transfers of Securities. The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.

                    (b) Upon surrender for registration of transfer of any
Security at the office or agency designated pursuant to Section 4.02, the
Company will execute, and the Trustee will authenticate and deliver, in the name
of the designated transferee or transferees, one or more new Securities of any
authorized denominations and of a like aggregate principal amount and tenor.

                    (c) At the option of the Holder, Securities may be exchanged
for other Securities of any authorized denominations and of a like aggregate
principal amount and tenor, upon surrender of the Securities to be exchanged at
such office or agency. Whenever any Securities are so surrendered for exchange,
the Company will execute, and the Trustee will authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

                    (d) Every Security presented or surrendered for registration
of transfer or exchange will (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument or instruments of
transfer, in form reasonably satisfactory to the Company and the Security
Registrar duly executed, by the Holder thereof or his attorney duly authorized
in writing. No service charge will be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 2.06 or 8.05 not involving any transfer.

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

SECTION 2.06.       TEMPORARY SECURITIES

                    Pending the preparation of definitive Securities, the
Company may execute and register, and upon Company Order the Trustee will
authenticate and deliver, temporary Securities (printed, lithographed, or
typewritten) of any authorized denomination, and substantially in the form of
the definitive Securities but with such omissions, insertions, and variations as
may be appropriate for temporary Securities, all as may be determined by the
officers of the Company executing such Securities as evidenced by their
execution of such Securities; PROVIDED, HOWEVER, that the Company will use
reasonable efforts to have definitive Securities available at the times


                                       17

<PAGE>



of any issuance of Securities under this Indenture. Every temporary Security
will be executed and registered by the Company and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Securities. The Company will execute and register
and furnish definitive Securities as soon as practicable and thereupon any or
all temporary Securities may be surrendered in exchange therefor at the office
or agency of the Company designated for such purpose pursuant to Section 4.02,
and the Trustee will authenticate and deliver in exchange for such temporary
Securities one or more definitive Securities of any authorized denominations,
and of a like aggregate principal amount and tenor. Such exchange will be made
by the Company at its own expense and without any charge to the Holder therefor.
Until so exchanged, the temporary Securities authenticated and delivered
hereunder will be entitled to the same benefits under this Indenture as
definitive Securities authenticated and delivered hereunder.

SECTION 2.07.       MUTILATED, DESTROYED, LOST, AND STOLEN SECURITIES

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

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

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

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

                    (e) Every new Security issued pursuant to this Section 2.07
in exchange for any mutilated Security or in lieu of any destroyed, lost, or
stolen Security will constitute an original additional contractual obligation of
the Company, whether or not the mutilated, destroyed, lost, or stolen Security
shall be at any time enforceable by anyone, and will be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Securities duly issued hereunder.

                    (f) The provisions of this Section 2.07 are exclusive and
will preclude (to the extent lawful) all other rights and remedies with respect
to the replacement or payment of mutilated, destroyed, lost, or stolen
Securities.

SECTION 2.08.       CANCELLATION OF SURRENDERED SECURITIES

                    All Securities surrendered for payment, redemption,
registration of transfer or exchange will, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and will be promptly canceled by
it. The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered will be promptly canceled by the Trustee. No
Securities will be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section 2.08, except as expressly permitted by this
Indenture. The Trustee shall destroy all canceled Securities held by the Trustee
and shall send a certificate of such destruction to the Company.

SECTION 2.09.       PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED

                    (a) The Securities shall bear interest during each Interest
Period at a rate per annum determined by the Company to be equal to the Canadian
LIBOR Rate plus the Margin, which determination will be final and binding. The
Company will notify the Trustee of the interest rate with respect to each
Interest Period no later than the first Business Day of such Interest Period.
The Securities will bear interest from September 9, 1999 (except that Securities
issued pursuant to Sections 2.01(c), 2.05 or 2.07 of this Indenture will bear
interest from the most recent Interest Payment Date to which interest on the
debt evidenced thereby has been paid or duly provided for and any Securities
issued upon the conversion of any 8% convertible subordinated debentures issued
by Forex under the Agency Indenture made as of March 12, 1997 between Forex,
Levesque Beaubien Geoffrion, Inc. and Laurentian Trust of Canada Inc. will bear
interest from the date of such conversion) until the principal thereof is paid
or made available for payment. Such interest shall be payable quarterly on
September 30, December 31, March 31 and June 30 of each year, commencing
December 31, 1999.

                    (b) The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name such Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest, which shall be
the fifteenth calendar day (whether or not a Business Day) next preceding such
Interest Payment Date.

                    (c) Any interest on any Security which is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") will forthwith cease to be payable to the Holder on
the relevant regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company together with interest thereon (to
the extent permitted by law) at the rate of interest applicable to such
Security, at its election in each case, as provided in clause (i) or (ii) below:

                           (i) The Company may elect to make payment of any
         Defaulted Interest (and interest thereon, if any) to the Persons in
         whose names the Securities (or their respective Predecessor Securities)
         are registered at the close of business on a Special


                                       19

<PAGE>



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

                           (ii) The Company may make payment of any Defaulted
         Interest (and interest thereon, if any) on the Securities in any other
         lawful manner if, after notice given by the Company to the Trustee of
         the proposed payment pursuant to this clause (ii), such manner of
         payment shall be deemed practicable by the Trustee.

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

                    (e) Payment of the Principal Installments and interest on
the Securities shall be made at the office or agency of the Company maintained
for the purpose in Montreal, Quebec, in such coin or currency of Canada as at
the time of payment is legal tender for payment of public and private debts;
PROVIDED, HOWEVER, that at the option of the Company payment of any Principal
Installment or interest may be made by check mailed to the address of the Person
entitled thereto as such address appears in the Security Register.

SECTION 2.10.       PERSONS DEEMED OWNERS

                    Prior to due presentment of a Security for registration of
transfer, the Company, the Guarantor, the Trustee, and any agent of the Company,
the Guarantor, or the Trustee may treat the Person in whose name such Security
is registered as the owner of such Security for the


                                       20

<PAGE>



purpose of receiving payment of principal of and (subject to Section 2.09) any
interest on such Security and for all other purposes whatsoever, whether or not
such Security shall be overdue, and none of the Company, the Guarantor, the
Trustee or any agent of the Company, the Guarantor or the Trustee will be
affected by notice to the contrary.

SECTION 2.11.       COMPUTATION OF INTEREST

                    Interest on the Securities will be computed on the basis of
a 360-day year consisting of twelve 30-day months.

                 ARTICLE III. DEFEASANCE AND COVENANT DEFEASANCE

SECTION 3.01.       DEFEASANCE AND DISCHARGE

                    The Company and the Guarantor will be deemed to have been
discharged from their respective obligations with respect to the Outstanding
Securities as provided in this Section 3.01 on and after the date the conditions
set forth in Section 3.03 are satisfied (hereinafter called "Defeasance"). For
this purpose, such Defeasance means that the Company will be deemed to have paid
and discharged the entire indebtedness represented by the Outstanding Securities
and the Company and the Guarantor will be deemed to have satisfied all of their
respective other obligations under the Securities and this Indenture (and the
Trustee, at the expense of the Company, will execute proper instruments
acknowledging the same), subject to the following which will survive until
otherwise terminated or discharged hereunder: (a) the rights of Holders of the
Securities to receive, solely from the trust fund described in Section 3.03 and
as more fully set forth in Section 3.03, payments in respect of the principal of
and interest on such Securities when payments are due, (b) the Company's
obligations with respect to the Securities under Sections 2.05, 2.06, 2.07,
4.02, 4.03, and 8.06, (c) the rights, powers, trusts, duties, and immunities of
the Trustee hereunder, and (d) this Article III.

SECTION 3.02.       COVENANT DEFEASANCE

                    The Company will be released from its obligations under
Sections 4.04 through 4.07, inclusive, Section 9.01, and the occurrence of any
event specified in Section 6.01(a)(iii) (with respect to any of Sections 4.04
through 4.07, inclusive and Section 9.01) will be deemed not to be or result in
an Event of Default, in each case with respect to the Outstanding Securities as
provided in this Section 3.02 on and after the date the conditions set forth in
Section 3.03 are satisfied (hereinafter called "Covenant Defeasance"). For this
purpose, such Covenant Defeasance means that the Company may omit to comply with
and will have no liability in respect of any term, condition, or limitation set
forth in any such specified Section (to the extent specified above in the case
of Section 6.01(a)(iii)), whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or provision or by reason of any
reference in any such Section or provision to any other provision herein or in
any other document, but the remainder of this Indenture and the Securities will
be unaffected thereby.

SECTION 3.03.       CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE

                    The following will be the conditions to application of
either Section 3.01 or Section 3.02 to the Outstanding Securities:

                    (a) The Company shall irrevocably have deposited or caused
         to be deposited with the Trustee as trust funds in trust for the
         benefit of the Holders of the Outstanding Securities money in an amount
         sufficient to pay and discharge, and which will be applied by the
         Trustee (or any such other qualifying trustee) to pay and discharge,
         the principal of and interest on the Securities on the respective
         Stated Maturities. The determination of the sufficiency of the amount
         of money so deposited shall be determined with reference to the rate of
         interest borne by the Securities at the time of such deposit.

                    (b) No Event of Default or event that (after notice or lapse
         of time or both) would become an Event of Default shall have occurred
         and be continuing at the time of such deposit or, with regard to any
         Event of Default or any such event specified in Sections 6.01(a)(iv)
         and (v), at any time on or prior to the 90th calendar day after the
         date of such deposit (it being understood that this condition will not
         be deemed satisfied until after such 90th calendar day).

                    (c) Such Defeasance or 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 is a party or by which it
         is bound.

                    (d) The Company shall have delivered to the Trustee an
         Officer's Certificate of the Company and an Opinion of Counsel, each
         stating that all conditions precedent with respect to such Defeasance
         or Covenant Defeasance have been complied with.

SECTION 3.04.       DEPOSITED MONEY TO BE HELD IN TRUST; OTHER MISCELLANEOUS
                    PROVISIONS

                    (a) Subject to the provisions of Section 4.03(e), all money
deposited with the Trustee or other qualifying trustee (solely for purposes of
this Section 3.04 and Section 3.05, the Trustee and any such other trustee are
referred to collectively as the "Trustee") pursuant to Section 3.03 in respect
of the Securities will be held in trust and applied by the Trustee, in
accordance with the provisions of the Securities and this Indenture, to the
payment, either directly or through any such Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
Securities, of all sums due and to become due thereon in respect of principal
and interest, but money so held in trust need not be segregated from other funds
except to the extent required by law.

                    (b) Notwithstanding anything in this Article III to the
contrary, (i) the Trustee will from time to time upon request deliver or pay to
the Company any money held by the Trustee as provided in Section 3.03 with
respect to the Securities that is in excess of the amount of money that would
then be required to be deposited to effect an equivalent Defeasance or Covenant
Defeasance with respect to the Securities and (ii) the Company will from time to
time


                                       22

<PAGE>



upon request deposit or cause to be deposited with the Trustee as trust funds in
trust for the benefit of the Holders of the Outstanding Securities such
additional amounts of money as may be necessary to cause the amount of money
held by the Trustee as provided in Section 3.03 with respect to the Securities
to be at least equal to the amount of money that would then be required to be
deposited to effect an equivalent Defeasance or Covenant Defeasance with respect
to the Securities.

SECTION 3.05.       REINSTATEMENT

                    If the Trustee or the Paying Agent is unable to apply any
money in accordance with this Article III with respect to the Securities by
reason of any order or judgment of any court or governmental authority
enjoining, restraining, or otherwise prohibiting such application, then the
Company's and the Guarantor's obligations under this Indenture and the
Securities will be revived and reinstated as though no deposit had occurred
pursuant to this Article III with respect to the Securities until such time as
the Trustee or Paying Agent is permitted to apply all money held in trust
pursuant to Section 3.04 with respect to the Securities in accordance with this
Article III; PROVIDED, HOWEVER, that if the Company makes any payment of
principal of or interest on the Securities following the reinstatement of its
obligations, the Company will be subrogated to the rights of the Holders of the
Securities to receive such payment from the money so held in trust.

                 ARTICLE IV. PARTICULAR COVENANTS OF THE COMPANY

SECTION 4.01.       PAYMENT OF PRINCIPAL AND INTEREST ON SECURITIES

SECTION 4.02.       MAINTENANCE OF OFFICE OR AGENCY

                    (a) The Company will maintain in Montreal, Quebec an office
or agency where the Securities may be presented or surrendered for payment,
where the Securities may be surrendered for registration of transfer or
exchange, and where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served. 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, and the Company hereby appoints
the Trustee as its agent to receive all such presentations, surrenders, notices,
and demands.

                    (b) 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 will in
any manner relieve the Company of its obligation to maintain an


                                       23

<PAGE>



office or agency in Montreal, Quebec for such purposes. The Company will give

of any change in the location of any such other office or agency.

SECTION 4.03.       MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST

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

                    (b) Whenever the Company shall have one or more Paying
Agents for the Securities, it will, prior to each due date of the principal of
or interest on any Securities, deposit with a Paying Agent a sum sufficient to
pay such amount, such sum to be held in trust by such Paying Agent for payment
in respect of the Securities, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

                    (c) The Company will cause each Paying Agent for the
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent will agree with the Trustee, subject to
the provisions of this Section 4.03, that such Paying Agent will, during the
continuance of any default by the Company (or any other obligor upon the
Securities) in the making of any payment in respect of the Securities, and upon
the written request of the Trustee, forthwith pay to the Trustee all sums held
in trust by such Paying Agent for payment in respect of the Securities.

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

                    (e) Any money deposited with the Trustee or any Paying
Agent, or then held by the Company, in trust for the payment of the principal of
or interest on any Security and remaining unclaimed for two years after such
principal or interest has become due and payable will be paid to the Company
upon a Company Request (or, if then held by the Company, will be discharged from
such trust); and the Holder of such Security will thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, will thereupon cease.

SECTION 4.04.       PAYMENT OF TAXES AND OTHER CLAIMS

                    The Company will pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (a) all taxes, assessments,
and governmental charges levied or imposed upon the Company or any Subsidiary of
the Company or upon the income, profits, or property of the Company or any
Subsidiary of the Company, and (b) all lawful claims for labor, materials, and
supplies, in each case which, if unpaid, might by law become a lien upon the
property of the Company or any Subsidiary of the Company and might have a
Material Adverse Effect; PROVIDED, HOWEVER, that the Company will not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge, or claim the amount, applicability, or validity of which is
being contested in good faith by appropriate proceedings.

SECTION 4.05.       MAINTENANCE OF PROPERTIES

                    The Company will cause all properties used or useful in the

with all necessary equipment and will cause to be made all necessary repairs,
renewals, replacements, betterments, and improvements thereof, all as in the
judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
PROVIDED, HOWEVER, that nothing in this Section 4.05 will prevent the Company
from discontinuing the operation or maintenance of any of such properties if
such discontinuance is, in the judgment of the Company, desirable in the conduct
of its business or the business of any Subsidiary of the Company and will not
result in a Material Adverse Effect.

SECTION 4.06.       EXISTENCE

                    Subject to Article IX, the Company will, and will cause each
of its Subsidiaries to, do or cause to be done all things necessary to preserve
and keep in full force and effect its existence, rights (charter and statutory),
and franchises; PROVIDED, HOWEVER, that no Subsidiary of the Company will be
required to preserve its existence, and neither the Company nor any Subsidiary
of the Company will be required to preserve any such right or franchise, if the
Board of Directors determines that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss
thereof will not result in a Material Adverse Effect.

SECTION 4.07.       COMPLIANCE WITH LAWS

                    The Company will, and will cause each of its Subsidiaries
to, comply with all applicable federal, state, local, or foreign laws, rules,
regulations, or ordinances, including without limitation such laws, rules,
regulations, or ordinances relating to pension, environmental, employee, and tax
matters, in each case to the extent that the failure so to comply would have a
Material Adverse Effect.

days after the end of each fiscal year of the Company ending after the date
hereof, an Officer's Certificate of the Company stating whether or not to the
knowledge of such person after due inquiry the Company is in default in the

with any term, provision, or condition set forth in Sections 4.04 through 4.07,
inclusive, with respect to the Securities if the Holders of a majority in
principal amount of the Outstanding Securities shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such term, provision, or condition, but no such waiver will extend to or affect
such term, provision, or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company

condition will remain in full force and effect.

SECTION 6.01.       EVENT OF DEFAULT

                    (a) "Event of Default," wherever used herein with respect to
the Securities, means any one of the following events (whatever the reason for
such Event of Default and whether it may be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree, or order of
any court or any order, rule, or regulation of any administrative or
governmental body):

                           (i) default in the payment of any interest on the
         Securities when it becomes due and payable, and continuance of such
         default for a period of 30 calendar days;

                           (ii) default in the payment of the principal of the

         covenant or warranty, a default in the performance or breach of which
         is elsewhere in this Section 6.01 specifically dealt with), and
         continuance of such default or breach for a period of 60 calendar days
         after there has been given, by registered or certified mail, to the
         Company by the Trustee or to the Company and the Trustee by the Holders
         of at least 25% in principal amount of the Outstanding Securities a
         written notice specifying such default or breach and requiring it to be
         remedied and stating that such notice is a "Notice of Default"
         hereunder;

                           (iv) the entry by a court having jurisdiction in the
         premises of (A) a decree or order for relief in respect of the Company
         in an involuntary case or proceeding under any applicable federal or
         provincial bankruptcy, insolvency, reorganization, or other similar law
         or (B) a decree or order adjudging the Company a bankrupt or insolvent,
         or approving as properly filed a petition seeking reorganization,
         arrangement, adjustment, or composition of or in respect of the Company
         under any applicable federal or provincial law, or appointing a
         custodian, receiver, liquidator, assignee, trustee, sequestrator, or
         other similar official of the Company or of any substantial part of its
         property, or ordering the winding up or liquidation of its affairs, and
         the continuance of any such decree or order for relief or any such
         other decree or order unstayed and in effect for a period of 60
         consecutive calendar days; or

                           (v) the commencement by the Company of a voluntary
         case or proceeding under any applicable federal or provincial
         bankruptcy, insolvency, reorganization, or other similar law or of any
         other case or proceeding to be adjudicated a bankrupt or insolvent, or
         the consent by it to the entry of a decree or order for relief in
         respect of the Company in an involuntary case or proceeding under any
         applicable federal or provincial bankruptcy, insolvency,
         reorganization, or other similar law or to the commencement of any
         bankruptcy or insolvency case or proceeding against it, or the filing
         by it of a petition or answer or consent seeking reorganization or

                                       27

<PAGE>



         to the Company under any applicable federal or provincial bankruptcy,
         insolvency, reorganization, or other similar law, or the consent by it
         to the filing of such petition or to the appointment of or taking
         possession by a custodian, receiver, liquidator, assignee, trustee,
         sequestrator, or other similar official of the Company or of any
         substantial part of its property pursuant to any such law, or the
         making by it of an assignment for the benefit of creditors, or the
         admission by it in writing of its inability to pay its debts generally
         as they become due, or the taking of corporate action by the Company in
         furtherance of any such action.

                    (b) If an Event of Default (other than an Event of Default
arising under Section 6.01(a)(iv) or (v)) with respect to Securities Outstanding
occurs and is continuing, then in every case the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities may declare the
principal amount of all of the Securities to be due and payable immediately, by
a notice in writing to the Company (and to the Trustee if given by Holders), and
upon any such declaration such principal amount (or specified amount) will
become immediately due and payable. If an Event of Default under Section
6.01(a)(iv) or (v) occurs, then the principal of, and accrued interest on, the
Securities shall become immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder.

                    (c) At any time after such a declaration of acceleration
with respect to the Securities has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article VI provided, the Holders of a majority in principal amount of the
Outstanding Securities, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if (i) the Company has
paid or deposited with the Trustee a sum sufficient to pay (A) all overdue
interest on the Securities, (B) the principal of any Securities which has become
due otherwise than by such declaration of acceleration and any interest thereon
at the rate or rates prescribed therefor in the Securities, (C) to the extent
that payment of such interest is lawful, interest upon overdue interest at the
rate or rates prescribed therefor in the Securities, and (D) all sums paid or
advanced by the Trustee hereunder and the reasonable compensation, expenses,
disbursements, and advances of the Trustee and its agents and counsel and (ii)
all Events of Default with respect to the Securities, other than the non-payment
of the principal of the Securities which has become due solely by such
declaration of acceleration, have been cured or waived as provided in Section
6.01(d). No such rescission will affect any subsequent default or impair any
right consequent thereon.

                    (d) The Holders of a majority in principal amount of the
Outstanding Securities may on behalf of the Holders of all the Securities waive
any past default hereunder and its consequences, except a default (i) in the
payment of the principal of or interest on the Securities or (ii) in respect of
a covenant or provision hereof which under Article VIII cannot be modified or
amended without the consent of the Holder of each Outstanding Security. Upon any
such waiver, such default will cease to exist, and any Event of Default arising
therefrom will be deemed to have been cured, for every purpose of this
Indenture, but no such waiver will extend to any subsequent or other default or
impair any right consequent thereon.

SECTION 6.02.       COVENANT OF COMPANY TO PAY TO TRUSTEE WHOLE AMOUNT
                    DUE ON SECURITIES ON DEFAULT IN PAYMENT OF INTEREST OR
                    PRINCIPAL; SUITS FOR ENFORCEMENT BY TRUSTEE

                    (a) The Company covenants that if (i) default is made in the
payment of any interest on the Securities when such interest becomes due and
payable and such default continues for a period of 30 calendar days or (ii)
default is made in the payment of the principal of the Securities when it
becomes due and payable, the Company will, upon demand of the Trustee, pay to
it, for the benefit of the Holders of the Securities, the whole amount then due
and payable on the Securities for principal and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and on any overdue interest, at the rate or rates prescribed therefor
in the Securities, and, in addition thereto, such further amount as will be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements, and advances of the Trustee
and its agents and counsel. If the Company shall fail forthwith to pay such
amounts upon such demand, the Trustee, in its own name and as trustee of an
express trust, shall be entitled and empowered to institute any actions or
proceedings at law or in equity for the collection of the sums so due and
unpaid, and may prosecute any such action or proceeding to judgment or final
decree, and may enforce any such judgment or final decree against the Company
and collect in the manner provided by law out of the property of the Company,
wherever situated, the moneys adjudged or decreed to be payable.

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

                    (c) In case of any judicial proceeding relative to the
Company (or any other obligor upon the Securities), its property, or its
creditors, the Trustee will be entitled and empowered, by intervention in such
proceeding or otherwise, to seek to have claims of the Holders and the Trustee
allowed in any such proceeding. In particular, the Trustee will be authorized to
collect and receive any money or other property payable or deliverable on any
such claims and to distribute the same, and any custodian, receiver, assignee,
trustee, liquidator, sequestrator, or other similar official in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee and, in the event that the Trustee consents to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements, and advances of the
Trustee and its agents and counsel, and any other amounts due the Trustee under
Section 7.06.

                    (d) No provision of this Indenture will be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any Holder any plan of reorganization, arrangement, adjustment, or composition
affecting the Securities or the rights of any Holder thereof or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding;
PROVIDED, HOWEVER, that the Trustee may, on behalf of the Holders, vote for the


                                       29

<PAGE>



election of a trustee in bankruptcy or similar official and be a member of a
creditors' or other similar committee.

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

SECTION 6.03.       APPLICATION OF MONEY COLLECTED BY TRUSTEE

                    Any money collected by the Trustee pursuant to this Article
VI will be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

                    FIRST:  To the payment of all amounts due the Trustee under
                            Section 7.06;

                    SECOND: To the payment of the amounts then due and unpaid
                            for principal of and interest on the Securities
                            ratably, without preference or priority of any kind,
                            according to the amounts due and payable on such
                            Securities for principal and interest, respectively;
                            and

                    THIRD:  To the Company, its successors or assigns, or to
                            such other Person that may be lawfully entitled to
                            receive the same.

SECTION 6.04.       LIMITATION ON SUITS BY HOLDERS OF SECURITIES

                    No Holder of any Security will have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless (a) such Holder has previously given written notice to the Trustee of a
continuing Event of Default, (b) the Holders of not less than 25% in principal
amount of the Outstanding Securities have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder, (c) such Holder or Holders have offered to the Trustee
reasonable indemnity against the costs, expenses, and liabilities to be incurred
in compliance with such request, (d) the Trustee for 60 calendar days after its
receipt of such notice, request, and offer of indemnity has failed to institute
any such proceeding, and (e) no direction inconsistent with such written request
has been given to the Trustee during such 60-day period by the Holders of a
majority in principal amount of the Outstanding Securities, it being understood
and intended that no one or more of such Holders will have any right in any
manner whatever by virtue of, or by availing of, any provision of this Indenture
to affect, disturb, or prejudice the rights of any other of such Holders, or to
obtain or to seek to obtain priority or preference over any other of such
Holders or to


                                       30

SECTION 6.05.       RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION IN
                    EXERCISE OF RIGHTS NOT A WAIVER OF EVENT OF DEFAULT

                    (a) Except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost, or stolen Securities in
the last paragraph of Section 2.07, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any
other right or remedy, and every right and remedy will, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, will not
prevent the concurrent assertion or employment of any other appropriate right or
remedy.

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

Securities, PROVIDED that (a) such direction will not be in conflict with any
rule of law or with this Indenture and (b) the Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such direction.

SECTION 6.07.       REQUIREMENT OF AN UNDERTAKING TO PAY COSTS IN CERTAIN
                    SUITS UNDER THE INDENTURE OR AGAINST THE TRUSTEE

                    In any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered, or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs against any such party litigant, in the manner and to the extent provided
by applicable law; PROVIDED, HOWEVER, this Section 6.07 will not be deemed to
authorize any court to require such an undertaking or to make such an assessment
in any suit instituted by the Company or by the Trustee.

becomes aware of or receives actual notice of such Event of Default.

SECTION 6.09.       UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND
                    INTEREST

                    Notwithstanding any other provision in this Indenture, the
Holder of any Security will have the right, which is absolute and unconditional,
to receive payment of the principal of and (subject to Section 2.09) interest on
such Security on the respective Stated Maturities expressed in such Security and
to institute suit for the enforcement of any such payment, and such rights may
not be impaired without the consent of such Holder.

SECTION 6.10.       RESTORATION OF RIGHTS AND REMEDIES

                    If the Trustee or any Holder has instituted any proceeding
to enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Guarantor, the Trustee, and
the Holders will be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders will continue as though no such proceeding had been instituted.

SECTION 6.11.       TRUSTEE MAY FILE PROOFS OF CLAIMS

                    The Trustee may file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements, and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceeding relative to the Company or the
Subsidiaries (or any other obligor upon the Securities), their creditors or
their property and shall be entitled and empowered to collect and receive any
monies or other property payable or deliverable on any such claim and to
distribute the same, and any custodian in any such judicial proceedings 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 hereunder. 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 or the rights of any Holder


                                       32

                    When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 6.01(a)(iv) or Section

SECTION 7.08.       CORPORATE TRUSTEE REQUIRED ELIGIBILITY

                    There will at all times be one or more Trustees hereunder
with respect to the Securities, at least one of which will be a Person that is a
corporation authorized to carry on the business of a trust company in the
Province of Quebec and has a combined capital and surplus of at least
C$100,000,000. If such Person publishes reports of condition at least annually,
pursuant to law or to the requirements of a supervising or examining provincial
or federal authority, then for the purposes of this Section 7.08, the combined
capital and surplus of such Person shall be deemed to be its combined capital
and surplus as set forth in its most recent report of condition so published. If
at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 7.08, it will resign immediately in the manner and
with the effect hereinafter specified in this Article VII.

SECTION 7.09.       RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR

                    (a) No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article VII will become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 7.10.

                    (b) The Trustee may resign at any time with respect to the
Securities by giving written notice thereof to the Company. If the instrument of
acceptance by a successor Trustee required by Section 7.10 shall not have been
delivered to the Trustee within 30 calendar days after the giving of such notice
of resignation, the resigning Trustee may at the expense of the Company petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities.

                    (c) The Trustee may be removed at any time with respect to
the Securities by Act of the Holders of a majority in principal amount of the
Outstanding Securities, delivered to the Trustee and to the Company.

                    (d) If, at any time, (i) the Trustee fails to comply with
Section 7.07 after written request therefor by the Company or by any Holder who
has been a bona fide Holder of a


                                       35

<PAGE>



Security for at least six months, (ii) the Trustee ceases to be eligible under
Section 7.08 and fails to resign after written request therefor by the Company
or by any such Holder, or (iii) the Trustee becomes incapable of acting or is
adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property
is appointed or any public officer takes charge or control of the Trustee or of
its property or affairs for the purpose of rehabilitation, conservation, or
liquidation, then, in any such case, (A) the Company by a Board Resolution may
remove the Trustee with respect to the Securities or (B) subject to Section
6.07, any Holder who has been a bona fide Holder of a Security for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee with respect to
all Securities and the appointment of a successor Trustee or Trustees.

                    (e) If the Trustee resigns, is removed, or becomes incapable
of acting, or if a vacancy occurs in the office of Trustee for any cause, with
respect to the Securities, the Company by a Board Resolution will promptly
appoint a successor Trustee or Trustees with respect to the Securities (it being
understood that at any time there will be only one Trustee with respect to the
Securities) and will comply with the applicable requirements of Section 7.10.
If, within one year after such resignation, removal, or incapability or the
occurrence of such vacancy, a successor Trustee with respect to the Securities
is appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities delivered to the Company and the retiring Trustee, the
successor Trustee so appointed will, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 7.10,
become the successor Trustee with respect to the Securities and to that extent
supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Securities shall have been so appointed by the
Company or the Holders and accepted appointment in the manner required by
Section 7.10, any Holder who has been a bona fide Holder of a Security for at
least six months may, on behalf of himself and all others similarly situated, at
the expense of the Company, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities.

                    (f) The Company will give notice of each resignation and
each removal of the Trustee with respect to the Securities and each appointment
of a successor Trustee with respect to the Securities to all holders of the
Securities in the manner provided in Section 12.03. Each notice will include the
name of the successor Trustee with respect to the Securities and the address of
its Corporate Trust Office.

SECTION 7.10.       ACCEPTANCE OF APPOINTMENT BY SUCCESSOR

                    (a) In case of the appointment hereunder of a successor
Trustee with respect to the Securities, every such successor Trustee so
appointed will execute, acknowledge, and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee will become effective and such
successor Trustee, without any further act, deed, or conveyance, will become
vested with all the rights, powers, trusts, and duties of the retiring Trustee,
but, on the request of the Company or the successor Trustee, such retiring
Trustee will, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers, and duties of


                                       36

<PAGE>



the retiring Trustee and will duly assign, transfer, and deliver to such Trustee
all property and money held by such retiring Trustee hereunder.

                    (b) Upon request of any such successor Trustee, the Company
will execute any and all instruments reasonably required to more fully and
certainly vest in and confirm to such successor Trustee all applicable rights,
powers, and trusts referred to in the preceding paragraphs of this Section 7.10.

                    (c) No successor Trustee will accept its appointment unless
at the time of such acceptance such successor Trustee is qualified and eligible
under this Article VII.

SECTION 7.11.       MERGER, CONVERSION, CONSOLIDATION, OR SUCCESSION TO
                    BUSINESS

                    Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion, or consolidation to which the Trustee may be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of the Trustee, will be the successor of the Trustee hereunder,
provided such corporation is otherwise qualified and eligible under this Article
VII, without the execution or filing of any paper or any further act on the part
of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion, or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

SECTION 7.12.       APPOINTMENT OF AUTHENTICATING AGENT

                    (a) The Trustee may appoint an Authenticating Agent or
Agents with respect to the Securities which will be authorized to act on behalf
of the Trustee to authenticate the Securities issued upon original issue and
upon exchange or registration of transfer thereof or pursuant to Section 2.07,
and the Securities so authenticated will be entitled to the benefits of this
Indenture and will be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference will be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of Canada or any province thereof authorized under such laws to
act as Authenticating Agent, having a combined capital and surplus of not less
than C$50,000,000 and subject to supervision or examination by federal or
provincial authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section 7.12,
the combined capital and surplus of such Authenticating Agent will be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in


                                       37

<PAGE>



accordance with the provisions of this Section 7.12, such Authenticating Agent
will resign immediately in the manner and with the effect specified in this
Section 7.12.

                    (b) Any corporation into which an Authenticating Agent may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion, or consolidation to which such
Authenticating Agent may be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, will
continue to be an Authenticating Agent, provided such corporation is otherwise
eligible under this Section 7.12, without the execution or filing of any paper
or any further act on the part of the Trustee or the Authenticating Agent.

                    (c) An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions this Section 7.12, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and will mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders as their
names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder will become
vested with all the rights, powers, and duties of its predecessor hereunder,
with like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent will be appointed unless eligible under the provisions of
this Section 7.12.

                    (d) The Company agrees to pay to each Authenticating Agent
from time to time reasonable compensation for its services under this Section
7.12.

                    (e) If an appointment with respect to the Securities is made
pursuant to this Section 7.12, the Securities may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative form of
certificate of authentication in the following form:

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

                                       39

<PAGE>



         provisions of this Indenture as may be necessary to provide for or
         facilitate the administration of the trusts hereunder by more than one
         Trustee, pursuant to the requirements of Section 7.10; or

                    (g) to cure any ambiguity, to correct or supplement any
         provision herein which may be defective or inconsistent with any other
         provision herein, or to make any other provisions with respect to
         matters or questions arising under this Indenture, PROVIDED that such
         action pursuant to this clause (h) will not adversely affect the
         interests of the Holders of the Securities in any material respect.

SECTION 8.02.       MODIFICATION OF INDENTURE WITH CONSENT OF HOLDERS OF AT
                    LEAST A MAJORITY IN PRINCIPAL AMOUNT OF OUTSTANDING
                    SECURITIES

                    (a) With the consent of the Holders of a majority in
principal amount of the Outstanding Securities, by Act of said Holders delivered
to the Company, the Guarantor, and the Trustee, the Company, the Guarantor, and
the Trustee may enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of modifying in any manner the rights
of the Holders of the Securities under this Indenture; PROVIDED, HOWEVER, that
no such supplemental indenture will, without the consent of the Holder of each
Outstanding Security:

                    (i) change the Stated Maturity of the principal of, or any
         installment of principal of or interest on, the Securities, or reduce
         the principal amount thereof or the rate of interest thereon, or change
         any place of payment where, or the coin or currency in which the
         principal of or interest on the Securities is payable, or impair the
         right to institute suit for the enforcement of any such payment on or
         after the Stated Maturity thereof;

                    (ii) reduce the percentage in principal amount of the
         Outstanding Securities, the consent of the Holders of which is required
         for any such supplemental indenture, or the consent of the Holders of
         which is required for any waiver (of compliance with certain provisions
         of this Indenture or certain defaults hereunder and their consequences)
         provided for in this Indenture; or

                    (iii) modify any of the provisions of this Section 8.02,
         Section 6.01(d) or Section 4.09, except to increase the percentage in
         principal amount of Holders required under any such Section or to
         provide that certain other provisions of this Indenture cannot be
         modified or waived without the consent of the Holder of each
         Outstanding Security, PROVIDED, HOWEVER, that this clause (iii) will
         not be deemed to require the consent of any Holder with respect to
         changes in the references to "the Trustee" and concomitant changes in
         this Section 8.02 and Section 4.09, or the deletion of this proviso, in
         accordance with the requirements of Sections 7.10 and 8.01(g).

<PAGE>



                    (b) It will not be necessary for any Act of Holders under
this Section 8.02 to approve the particular form of any proposed supplemental
indenture, but it will be sufficient if such Act approves the substance thereof.

SECTION 8.03.       EXECUTION OF SUPPLEMENTAL INDENTURES

                    In executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article VIII or the modifications
thereby of the trusts created by this Indenture, the Trustee will be entitled to
receive, and (subject to Section 7.01) will be fully protected in relying upon,
an Officers' Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but will not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties, or immunities under
this Indenture or otherwise.

SECTION 8.04.       EFFECT OF SUPPLEMENTAL INDENTURES

                    Upon the execution of any supplemental indenture under this
Article VIII, this Indenture will be modified in accordance therewith, and such
supplemental indenture will form a part of this Indenture for all purposes; and
every Holder of Securities theretofore or thereafter authenticated and delivered
hereunder will be bound thereby.

SECTION 8.05.       REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES

                    Securities authenticated and delivered after the execution
of any supplemental indenture pursuant to this Article VIII may, and will if
required by the Trustee, bear a notation in form approved by the Trustee as to
any matter provided for in such supplemental indenture. If the Company shall so
determine, new Securities so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for the Outstanding Securities.

              ARTICLE IX. CONSOLIDATION, MERGER, SALE, OR TRANSFER

SECTION 9.01.       CONSOLIDATIONS AND MERGERS OF COMPANY AND SALES
                    PERMITTED ONLY ON CERTAIN TERMS

                    (a) The Company shall not consolidate with or merge with or
into any other Person, or transfer (by lease, assignment, sale, or otherwise)
all or substantially all of its properties and assets to another Person unless
(i) either (A) the Company shall be the continuing or surviving Person in such a
consolidation or merger or (B) the Person (if other than the Company) formed by
such consolidation or into which the Company is merged or to which all or
substantially all of the properties and assets of the Company are transferred
(the Company or such other Person being referred to as the "Surviving Person")
shall be a corporation organized and validly existing under the laws of Canada
or any province thereof, and shall expressly assume, by an indenture
supplemental hereto, all of the obligations of the Company under the Securities
and the Indenture, (ii) immediately after the transaction no Default will exist,
and (iii)


                                       41

<PAGE>



an Officer's Certificate of the Company has been delivered to the Trustee to the
effect that the conditions set forth in the preceding clauses (i) and (ii) have
been satisfied and an Opinion of Counsel (from a counsel who shall not be an
employee of the Company) has been delivered to the Trustee to the effect that
the conditions set forth in the preceding clause (i) have been satisfied.

                    (b) The Surviving Person will succeed to and be substituted
for the Company with the same effect as if it had been named herein as a party
hereto, and thereafter the predecessor corporation will be relieved of all
obligations and covenants under this Indenture and the Securities.

               ARTICLE X. SATISFACTION AND DISCHARGE OF INDENTURE

SECTION 10.01.      SATISFACTION AND DISCHARGE OF INDENTURE

                    This Indenture will upon a Company Request cease to be of
further effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for), and the Trustee, at the
expense of the Company, will execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when: (a) either (i) all
Securities theretofore authenticated and delivered (other than (A) Securities
which have been destroyed, lost, or stolen and which have been replaced or paid
as provided in Section 2.07 and (B) Securities for the payment of which money
has theretofore been deposited in trust or segregated and held in trust by the
Company and thereafter repaid to the Company or discharged from such trust, as
provided in Section 4.03) have been delivered to the Trustee for cancellation or
(ii) all such Securities not theretofore delivered to the Trustee for
cancellation (A) have become due and payable or (B) will become due and payable
at their Stated Maturity within one year, and the Company, in the case of clause
(A) or (B) above, has deposited or caused to be deposited with the Trustee as
trust funds in trust for such purpose an amount sufficient to pay and discharge
the entire indebtedness on such Securities not theretofore delivered to the
Trustee for cancellation, for principal and interest to the date of such deposit
(in the case of Securities which have become due and payable) or to the Stated
Maturity; (b) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and (c) the Company has delivered to the Trustee an
Officer's Certificate of the Company and an Opinion of Counsel, each stating
that all conditions precedent herein provided for relating to the satisfaction
and discharge of this Indenture have been satisfied. Notwithstanding the
satisfaction and discharge of this Indenture, the obligations of the Company to
the Trustee under Section 7.06, the obligations of the Trustee to any
Authenticating Agent under Section 7.12, and, if money shall have been deposited
with the Trustee pursuant to subclause (ii) of clause (a) of this Section 10.01,
the obligations of the Trustee under Sections 4.03(e) and 10.02, will survive.

SECTION 10.02.      APPLICATION OF TRUST MONEY

                    Subject to provisions of Section 4.03(e), all money
deposited with the Trustee pursuant to Section 10.01 will be held in trust and
applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may


                                       42

<PAGE>



determine, to the Persons entitled thereto, of the principal and interest for
the payment of which such money has been deposited with the Trustee; and such
money shall be segregated from other funds to the extent required by law.

                              ARTICLE XI. GUARANTEE

SECTION 11.01.      GUARANTEE

                    The Guarantor hereby unconditionally guarantees, to the
extent permitted by law, to each Holder of a Security executed by the Company
and authenticated by the Trustee and delivered as provided in this Indenture,
and to the Trustee on behalf of such Holder, that: (a) the principal of and
interest on the Securities will be promptly paid in full when due, whether at
Maturity, by acceleration, or otherwise, and interest on the overdue principal
of and interest on the Securities, if any, will be promptly paid in full in
accordance with the terms thereof and hereof and (b) in case of any extension of
time of payment or renewal of any Securities, the same will be promptly paid in
full when due in accordance with the terms of the extension or renewal, whether
at Maturity, by acceleration, or otherwise. Failing payment when due of any
amount so guaranteed for whatever reason, the Guarantor will be obligated to pay
the same immediately. The Guarantor hereby agrees that its obligations hereunder
shall be unconditional, irrespective of any waiver or consent by any Holder of
the Securities with respect to any provisions of this Indenture or the
Securities. The foregoing Guarantee shall rank PARI PASSU in right of payment
with all other unsecured and unsubordinated indebtedness of the Guarantor.

                    The Guarantor shall be subrogated to all rights of each
Holder of the Securities against the Company in respect of any amounts paid to
the Holders by the Guarantor pursuant to the provisions of the Guarantee;
provided that the Guarantor shall not be entitled to enforce, or to receive any
payments arising out of or based upon, such right of subrogation until the
principal of and interest (including additional amounts, if any) on all the
Securities shall have been paid in full.

SECTION 11.02.      EXECUTION AND DELIVERY OF GUARANTEE

                    To evidence its Guarantee set forth in Section 11.01 hereof,
the Guarantor hereby agrees that a notation of such Guarantee substantially in
the form set forth in the Form of Security in the Recitals hereto shall be
endorsed (manually or by facsimile) by an officer of the Guarantor on each
Security authenticated and delivered by the Trustee and that this Indenture
shall be executed on behalf of the Guarantor by its Chairman, Vice Chairman,
President, Chief Executive Officer or one of its Vice Presidents and attested to
by the Treasurer, an Assistant Treasurer, the Secretary or an Assistant
Secretary.

                    If an officer whose signature is on this Indenture or on the
Guarantee no longer holds that office at the time the Trustee authenticates the
Security on which a Guarantee is endorsed, the Guarantee shall be valid, binding
and enforceable nevertheless.

                    The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of the Guarantee
endorsed thereon on behalf of the


                                       43

<PAGE>



Guarantor. The Guarantor hereby agrees that its Guarantee set forth in Section
11.01 shall remain in full force and effect notwithstanding any failure to
endorse on each Security a notation of such Guarantee.

SECTION 11.03.      CONSOLIDATIONS AND MERGERS OF GUARANTOR AND SALES
                    PERMITTED ONLY ON CERTAIN TERMS

                    (a) The Guarantor shall not consolidate with or merge with
or into any other Person, or transfer (by lease, assignment, sale, or otherwise)
all or substantially all of its properties and assets to another Person unless
(i) either (A) the Guarantor shall be the continuing or surviving Person in such
a consolidation or merger or (B) the Person (if other than the Guarantor) formed
by such consolidation or into which the Guarantor is merged or to which all or
substantially all of the properties and assets of the Guarantor are transferred
(the Guarantor or such other Person being referred to as the "Guarantor
Surviving Person") shall be a corporation organized and validly existing under
the laws of the United States, any state thereof, or the District of Columbia,
and shall expressly assume, by an indenture supplemental hereto, all of the
obligations of the Guarantor under the Securities and this Indenture, (ii)
immediately after the transaction, no Default will exist, and (iii) an Officer's
Certificate has been delivered to the Trustee to the effect that the conditions
set forth in the preceding clauses (i) and (ii) have been satisfied and an
Opinion of Counsel (from a counsel who shall not be an employee of the
Guarantor) has been delivered to the Trustee to the effect that the conditions
set forth in the preceding clause (i) have been satisfied.

                    (b) The Guarantor Surviving Person will succeed to and be
substituted for the Guarantor with the same effect as if it had been named
herein as a party hereto, and thereafter the predecessor corporation will be
relieved of all obligations and covenants under this Indenture and the
Securities.

                      ARTICLE XII. MISCELLANEOUS PROVISIONS

SECTION 12.01.      SUCCESSORS AND ASSIGNS OF COMPANY BOUND BY INDENTURE

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

SECTION 12.02.      SERVICE OF REQUIRED NOTICE TO TRUSTEE AND COMPANY

                    Any request, demand, authorization, direction, notice,
consent, waiver, Act of Holders, or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with (a) the Trustee
by any Holder, by the Company, or by the Guarantor will be sufficient for every
purpose hereunder if made, given, furnished, or filed in writing to or with the
Trustee at its Corporate Trust Office, (b) the Company by any Holder, by the
Trustee, or by the Guarantor will be sufficient for every purpose hereunder
(unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to the Company addressed to it care of
Louisiana-Pacific Corporation, 111 S.W. Fifth Avenue, Portland, Oregon


                                       44

<PAGE>



97204 (marked for the attention of both the Chief Financial Officer and the
General Counsel) or at any other address previously furnished in writing to the
Trustee by the Company, (c) the Guarantor by any Holder, by the Trustee, or by
the Company will be sufficient for every purpose hereunder (unless otherwise
herein expressly provided) if in writing and mailed, first-class postage
prepaid, to the Guarantor addressed to it at 111 S.W. Fifth Avenue, Portland,
Oregon 97204 (marked for the attention of both the Chief Financial Officer and
the General Counsel) or at any other address previously furnished in writing to
the Trustee by the Guarantor.

SECTION 12.03.      SERVICE OF REQUIRED NOTICE TO HOLDERS; WAIVER

                    Where this Indenture provides for notice to Holders of any
event, such notice will be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at his address as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder will affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver will be the equivalent of such notice. Waivers of notice by Holders
will be filed with the Trustee, but such filing will not be a condition
precedent to the validity of any action taken in reliance upon such waiver. In
case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as may be made with the approval of the Trustee will constitute a
sufficient notification for every purpose hereunder.

SECTION 12.04.      INDENTURE AND SECURITIES TO BE CONSTRUED IN ACCORDANCE
                    WITH THE LAWS OF THE STATE OF NEW YORK

                    This Indenture and the Securities will be deemed to be a
contract made under the laws of the State of New York, and for all purposes will
be construed in accordance with the laws of said State without giving effect to
principles of conflict of laws of such State.

SECTION 12.05.      COMPLIANCE CERTIFICATES AND OPINIONS

                    Upon any application or request by the Company or the
Guarantor to the Trustee to take any action under any of the provisions of this
Indenture, the Company or the Guarantor, as applicable, will furnish to the
Trustee such certificates and opinions as may be required by this Indenture.
Each such certificate or opinion will be given in the form of an Officer's
Certificate, if to be given by an officer of the Company or the Guarantor, as
applicable, or an Opinion of Counsel, if to be given by counsel, and will comply
with any other requirements set forth in this Indenture.



                                       45

<PAGE>



SECTION 12.06.      FORM OF DOCUMENTS DELIVERED TO TRUSTEE

                    In any case where several matters are required to be
certified by, or covered by an opinion of, any specified Person, it is not
necessary that all such matters be certified by, or covered by the opinion of,
only one such Person, or that they be so certified or covered by only one
document, but one such Person may certify or give an opinion with respect to
some matters and one or more other such Persons as to other matters, and any
such Person may certify or give an opinion as to such matters in one or several
documents. Where any Person is required to make, give, or execute two or more
applications, requests, consents, certificates, statements, opinions, or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

SECTION 12.07.      PAYMENTS DUE ON NON-BUSINESS DAYS

                    In any case where any Interest Payment Date or Maturity Date
shall not be a Business Day, then (notwithstanding any other provision of this
Indenture or of the Securities) payment of interest or principal need not be
made on such date, but may be made on the next succeeding Business Day, without
additional interest, with the same force and effect as if made on the applicable
Interest Payment Date or Maturity Date, as the case may be.

SECTION 12.08.      INVALIDITY OF PARTICULAR PROVISIONS

                    In case any one or more of the provisions contained in this
Indenture or in the Securities is for any reason held to be invalid, illegal, or
unenforceable in any respect, such validity, illegality, or enforceability will
not affect any other provision of this Indenture or of the Securities, but this
Indenture and such Securities will be construed as if such invalid, illegal, or
unenforceable provision had never been contained herein or therein.

SECTION 12.09.      INDENTURE MAY BE EXECUTED IN COUNTERPARTS

                    This instrument may be executed in any number of
counterparts, each of which will be an original, but such counterparts will
together constitute but one and the same instrument.

SECTION 12.10.      ACTS OF HOLDERS; RECORD DATES

                    (a) Any request, demand, authorization, direction, notice,
consent, waiver, or other action provided or permitted by this Indenture to be
given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action will become effective when such instrument or instruments
are delivered to the Trustee and, where it is hereby expressly required, to the
Company or the Guarantor. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent will be
sufficient for any purpose of this Indenture and (subject to Section 7.01)
conclusive in


                                       46

<PAGE>



favor of the Trustee, the Company or the Guarantor, if made in the manner
provided in this Section 12.10.

                    (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit will also constitute sufficient proof of
his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

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

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

                    (e) The Company may set any day as the record date for the
purpose of determining the Holders of Outstanding Securities entitled to give or
take any request, demand, authorization, direction, notice, consent, waiver, or
other action provided or permitted by this Indenture to be given or taken by the
Holders. With regard to any record date set pursuant to this paragraph, the
Holders on such record date (or their duly appointed agents), and only such
Persons, will be entitled to give or take the relevant action, whether or not
such Holders remain Holders after such record date. With regard to any action
that may be given or taken hereunder only by Holders of a requisite principal
amount of Outstanding Securities (or their duly appointed agents) and for which
a record date is set pursuant to this paragraph, the Company may, at its option,
set an expiration date after which no such action purported to be given or taken
by any Holder will be effective hereunder unless given or taken on or prior to
such expiration date by Holders of the requisite principal amount of Outstanding
Securities on such record date (or their duly appointed agents). On or prior to
any expiration date set pursuant to this paragraph, the Company may, on one or
more occasions at its option, extend such date to any later date. Nothing in
this paragraph will prevent any Holder (or any duly appointed agent thereof)
from giving or taking, after any such expiration date, any action identical to,
or, at any time, contrary to or different from, the action or purported action
to which such expiration date relates, in which event the Company may set a
record date in respect thereof pursuant to this paragraph. Nothing in this
Section 12.10(e) will be construed to render ineffective any action taken at any
time by the Holders (or their duly appointed agents) of the requisite principal
amount of Outstanding Securities on the date such action is so taken.
Notwithstanding the foregoing, the Company will not set a record date for, and
the provisions of this Section 12.10(e) will not apply with respect to, any
notice, declaration, or direction referred to in the next paragraph.



                                       47

<PAGE>



                    (f) Upon receipt by the Trustee from any Holder of
Securities of (a) any notice of default or breach referred to in Section
6.01(a)(iii) with respect to the Securities, if such default or breach has
occurred and is continuing and the Trustee shall not have given such notice to
the Company, (b) any declaration of acceleration referred to in Section 6.01(b),
if an Event of Default with respect to the Securities has occurred and is
continuing and the Trustee shall not have given such a declaration to the
Company, or (c) any direction referred to in Section 6.06 with respect to the
Securities, if the Trustee shall not have taken the action specified in such
direction, then a record date will automatically and without any action by the
Company or the Trustee be set for determining the Holders of the Outstanding
Securities entitled to join in such notice, declaration, or direction, which
record date will be the close of business on the tenth calendar day following
the day on which the Trustee receives such notice, declaration, or direction.
Promptly after such receipt by the Trustee, and in any case not later than the
fifth calendar day thereafter, the Trustee will notify the Company and the
Holders of the Outstanding Securities of any such record date so fixed. The
Holders of the Outstanding Securities on such record date (or their duly
appointed agents), and only such Persons, will be entitled to join in such
notice, declaration, or direction, whether or not such Holders remain Holders
after such record date; PROVIDED that, unless such notice, declaration, or
direction shall have become effective by virtue of Holders of the requisite
principal amount of the Outstanding Securities on such record date (or their
duly appointed agents) having joined therein on or prior to the 90th calendar
day after such record date, such notice, declaration, or direction will
automatically and without any action by any Person be canceled and of no further
effect. Nothing in this Section 12.10(f) will be construed to prevent a Holder
(or a duly appointed agent thereof) from giving, before or after the expiration
of such 90-day period, a notice, declaration, or direction contrary to or
different from, or, after the expiration of such period, identical to, the
notice, declaration, or direction to which such record date relates, in which
event a new record date in respect thereof will be set pursuant to this Section
12.10(f). Nothing in this Section 12.10(f) will be construed to render
ineffective any notice, declaration, or direction of the type referred to in
