portion of such Canadian Borrowing in Canadian Dollars.  Promptly after (i) the
Canadian Administrative Agent's receipt of such funds and (ii) fulfillment of
the applicable conditions set forth in Article III (which fulfillment the
Canadian Administrative Agent may assume in the absence of actual knowledge, or
notice received from either Borrower or the Required Banks, to the contrary),
the Canadian Administrative Agent will make such funds available to the
Canadian Borrower at an account in Canada designated by the Canadian Borrower
in the Notice of Canadian Borrowing or, if the Canadian Borrower does not so
designate, the Canadian Administrative Agent's aforesaid address.

              (c)     Each Notice of Borrowing shall be irrevocable and binding
on the Borrowers.  In the case of any Borrowing that the related Notice of
Borrowing specifies is to be comprised of Eurodollar Rate Advances or CD Rate
Advances, the U.S. Borrower shall indemnify each Bank against any loss, cost or
expense actually incurred by such Bank as a result of any failure by the U.S.
Borrower to fulfill on or before the date specified in such Notice of Borrowing
for such Borrowing the applicable conditions set forth in Article III,
including any loss (excluding loss of anticipated profits), cost or expense
actually incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Bank to fund the Advance to be made by such Bank
as part of such Borrowing when such Advance, as a result of such failure, is
not made on such date.

              (d)     Unless the Administrative Agent to which a Notice of U.S.
Borrowing or a Notice of Canadian Borrowing has been given shall have received
notice from a Bank prior to the date of any Borrowing that such Bank will not
make available to such Administrative Agent such Bank's ratable portion of such
Borrowing, such Administrative Agent may assume that such Bank has made such
portion available to such Administrative Agent on the date of such Borrowing in
accordance with this Section 2.02 and such Administrative Agent may, in
reliance upon such assumption, make available to the appropriate Borrower on
such date a corresponding amount.  If and to the extent that such Bank shall
not have so made such ratable portion available to such Administrative Agent,
such Bank and the Borrower receiving such corresponding amount severally agree
to repay to such Administrative Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date such amount
is made available to such Borrower until the date such amount is repaid to such
Administrative Agent, at (i) in the case of such Borrower, the interest rate
applicable at the time to Advances comprising such Borrowing and (ii) in the
case of such Bank, (a) if such Borrowing is a U.S. Borrowing, the Federal Funds
Rate and (b) if such Borrowing is a Canadian Borrowing, the Canadian Interbank
Rate.  If such Bank shall repay to such Administrative Agent such corresponding
amount, such amount so repaid shall constitute such Bank's Advance as part of
such Borrowing for all purposes.

              (e)      The failure of any Bank to make the Advance to be made
by it as part of any Borrowing shall not relieve any other Bank of its
obligation, if any, hereunder to make its Advance on the date of such
Borrowing, but no Bank shall be responsible for the failure of any other Bank
to make the Advance to be made by such other Bank on the date of any Borrowing.

              (f)     The indebtedness of the U.S. Borrower to each U.S. Bank
resulting from Advances owing to such Bank shall be evidenced by a U.S. Note
payable to the order of such Bank in substantially the form of Exhibit A.  The
indebtedness of the Canadian Borrower to each Canadian Bank resulting from
Advances owing to such Bank shall be evidenced by a Canadian Note payable to
the order of such Bank in substantially the form of Exhibit B.

     Section 2.03.    Drawings of BA Obligations.  (a) Each Drawing shall be
made on notice, given not later than 12:00 noon (New York City time) on the
third Canadian Business Day prior to the date of the proposed Drawing, by the
Canadian Borrower to the U.S. Administrative Agent, which shall give the
Canadian Administrative Agent and each Canadian Bank prompt notice thereof by
telecopier.  Each notice of a Drawing (a "Notice of Drawing") shall be by
telecopier, in substantially the form of Exhibit L, specifying therein the
requested (i) date of such Drawing (which shall be a Canadian Business Day),
(ii) aggregate Face Amount of such Drawing, and (iii) the Maturity Date for
each BA Obligation comprising part of such Drawing.  Each Draft and BA
Equivalent Note in connection with any requested Drawing (A) shall be in an
amount of C$100,000 or an integral multiple of C$100,000 in excess thereof, and
(B) shall be dated the date of the proposed Drawing.  In the event that the
Face Amount of any Drawing requested by the Canadian Borrower pursuant to any
Notice of Drawing is an amount which, if divided ratably among the Canadian
Banks would not result in each Canadian Bank accepting a Draft or purchasing a
BA Equivalent Note which has an undiscounted face amount equal to C$100,000 or
an integral multiple of C$100,000 in excess thereof, then notwithstanding any
provision in this Agreement to the contrary, the Canadian Administrative Agent
is authorized by the Canadian Borrower and the Canadian Banks to allocate among
the Canadian Banks, the Drafts to be accepted and purchased and BA Equivalent
Notes to be purchased in such manner and amounts as the Canadian Administrative
Agent may, in its sole discretion, acting reasonably, consider necessary,
rounding up or down, so as to ensure that no Canadian Bank is required to
accept a Draft for a fraction of $100,000 and, in such event, the Canadian
Banks' ratable share with respect to such Drafts and BA Equivalent Notes shall
be adjusted accordingly; provided that no Canadian Bank shall be required to
purchase any Bankers' Acceptance or BA Equivalent Note to the extent that the
Face Amount thereof exceeds its then Unused Commitment and such Canadian Bank
shall fund any portion of its allocated share in excess of its Bankers'
Acceptance or BA Equivalent Note in the form of a Canadian Prime Rate Advance,
which shall for all purposes be deemed to be a Canadian Borrower Advance made
pursuant to Section 2.01(b).  Each Canadian Bank shall, before 12:00 noon (New
York City time) on the date of each Drawing, (1) in the case of each Canadian
Bank able to complete and accept bankers' acceptances in Canada, complete one
or more





                                      -40-
<PAGE>   46
Drafts in accordance with the related Notice of Drawing, accept such Drafts and
purchase the Bankers' Acceptances created thereby for the Drawing Purchase
Price, or (2) in the case of each Canadian Bank that is not able to complete
and accept bankers' acceptances in Canada, complete one or more BA Equivalent
Notes in accordance with the related Notice of Drawing and purchase such
completed BA Equivalent Notes for the Drawing Purchase Price, and, in any case,
shall, before 12:00 noon (New York City time) on such date, make available for
the account of its Applicable Lending Office to the Canadian Administrative
Agent at its address referenced to in Section 8.02, in same day funds, the
Drawing Purchase Price payable by such Bank for such Drawing less the Drawing
Fee payable to such Bank with respect thereto under Section 2.06(d).  Promptly
after the fulfillment of the applicable conditions set forth in Article III
(which fulfillment the Canadian Administrative Agent may assume in the absence
of actual knowledge, or notice received from either Borrower or the Required
Banks, to the contrary), the Canadian Administrative Agent will make the funds
it has received from the Canadian Banks available to the Canadian Borrower at
an account in Canada designated by the Canadian Borrower in the Notice of
Canadian Borrowing or, if the Canadian Borrower does not so designate, the
Canadian Administrative Agent's aforesaid address.

              (b)     Anything in Section 2.03(a) to the contrary
notwithstanding, the Canadian Borrower may not select a Drawing if the
obligation of the Canadian Banks to purchase Bankers' Acceptances shall then be
suspended pursuant to Section 2.03(d), Section 2.08 or Section 2.14.

              (c)     Each Notice of Drawing shall be irrevocable and binding
on the Canadian Borrower.  In the case of any proposed Drawing, the Canadian
Borrower shall indemnify each Canadian Bank against any loss, cost or expense
actually incurred by such Bank as a result of any failure by the Canadian
Borrower to fulfill on or before the date specified in the Notice of Drawing
for such Drawing the applicable conditions set forth in Article III, including,
without limitation, any loss (excluding loss of anticipated profits), cost or
expense actually incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by such Bank to fund the Drawing Purchase
Price to be paid by such Bank as part of such Drawing when, as a result of such
failure, such Drawing is not made on such date.

              (d)     (i) If, with respect to any proposed Drawing, the
Canadian Administrative Agent determines in good faith that circumstances
affecting the money markets at the time any related Notice of Drawing is
delivered or is outstanding will result in no market for the Bankers'
Acceptances to be created in connection with such Drawing or an insufficient
demand for such Bankers' Acceptances to allow the Banks





                                      -41-
<PAGE>   47
creating such Bankers' Acceptances to sell or trade the Bankers' Acceptances to
be created and purchased or discounted by them hereunder in connection with
such Drawing, then, upon notice to the Canadian Borrower and the Canadian Banks
thereof, (A) the Drawing requested therein shall not be made and the Notice of
Drawing with respect to such proposed Drawing shall be deemed to be a Notice of
Canadian Borrowing requesting a Canadian Borrowing in an amount equal to the
requested Face Amount of such Drawing and (B) the right of the Canadian
Borrower to request a Drawing, and the obligation of the Canadian Banks to
complete and accept Drafts and/or to purchase Bankers' Acceptances or BA
Equivalent Notes, shall be suspended until the Canadian Administrative Agent
shall notify such Borrower that the circumstances causing such suspension no
longer exist.

                      (ii) Upon the occurrence and during the continuance of
any Event of Default under Section 6.01(a) or Section 6.01(e), the obligation
of the Canadian Banks to purchase and/or accept BA Obligations, and the right
of the Canadian Borrower to request a Drawing, shall be suspended.

              (e)     Unless the Canadian Administrative Agent shall have
received notice from a Canadian Bank prior to the date of any Drawing that such
Bank will not make available to it such Bank's ratable share of such Drawing in
accordance with Section 2.03(a), such Administrative Agent may assume that such
Bank has made such ratable share available to it on the date of such Drawing in
accordance with Section 2.03(a) and such Administrative Agent may, in reliance
upon such assumption, make available to the Canadian Borrower on such date a
corresponding amount.  If and to the extent that any such Bank shall not have
so made such ratable share available to the Canadian Administrative Agent, such
Bank and the Canadian Borrower severally agree to repay to the Canadian
Administrative Agent forthwith on demand such corresponding amount, together
with interest thereon, for each day from the date such amount is made available
to such Borrower until the date such amount is repaid to such Administrative
Agent, at (i) in the case of the Canadian Borrower, a rate per annum equal to
the annual yield resulting from application of the Bankers' Acceptance Rate
used in calculating the Drawing Purchase Price with respect to such Drawing,
and (ii) in the case of such Bank, the Canadian Interbank Rate.  If such Bank
shall pay to the Canadian Administrative Agent such corresponding amount, such
amount so paid shall constitute such Bank's BA Obligation as part of such
Drawing for all purposes under this Agreement.

              (f)     To enable the Canadian Banks to create Bankers'
Acceptances or to complete BA Equivalent Notes in accordance with Section
2.01(c) and this Section 2.03, the Canadian Borrower shall supply each Canadian
Bank, (i) upon the Canadian





                                      -42-
<PAGE>   48
Borrower's execution of this Agreement, with such number of Drafts and signed
blank BA Equivalent Notes provided to the Canadian Borrower by the Canadian
Administrative Agent as the Canadian Administrative Agent may reasonably
request and (ii) after the date hereof, such number of Drafts and signed blank
BA Equivalent Notes provided to the Canadian Borrower by the Canadian
Administrative Agent as the Canadian Administrative Agent may from time to time
reasonably request, in each case duly endorsed and executed on behalf of the
Canadian Borrower by any one or more of its duly authorized officers.  Each
Canadian Bank shall exercise such care in the custody and safekeeping of any
Drafts and BA Equivalent Notes in its possession from time to time as it would
exercise in the custody and safekeeping of similar property owned by it.  The
signatures of officers of the Canadian Borrower on Drafts and BA Equivalent
Notes may be mechanically reproduced in facsimile and Bankers' Acceptances and
BA Equivalent Notes bearing such facsimile signatures shall be binding upon the
Canadian Borrower as if they had been manually signed by such officers.
Notwithstanding that any of the individuals whose manual or facsimile signature
appears on any Draft or BA Equivalent Note as one of such officers may no
longer hold office at the date of such draft or at the date of its acceptance
by a Bank hereunder or at any time thereafter, any Draft or Bankers' Acceptance
or BA Equivalent Note so signed shall be valid and binding upon, and
enforceable against, the Canadian Borrower.

              (g)     Bankers' Acceptances purchased by a Canadian Bank in
accordance with the terms of Section 2.01(c), Section 2.03 or Section 2.19 may,
in such Bank's sole discretion, be held by such Bank for its own account until
the applicable Maturity Date or sold, rediscounted or otherwise disposed of by
it at any time prior thereto in any relevant market therefor.

              (h)     The failure of any Canadian Bank to fund the Drawing
Purchase Price to be funded by it as part of any Drawing shall not relieve any
other Canadian Bank of its obligation hereunder to fund its Drawing Purchase
Price on the date of such Drawing, but no Canadian Bank shall be responsible
for the failure of any other Canadian Bank to fund the Drawing Purchase Price
to be funded by such other Canadian Bank on the date of any Drawing.

     Section 2.04.    Fees; Reduction of Commitments.  (a)  The U.S. Borrower
agrees to pay to the U.S. Administrative Agent for the account of each U.S.
Bank a commitment fee on the average daily Unused Commitment of such U.S. Bank.
The Canadian Borrower agrees to pay to the Canadian Administrative Agent for
the account of each Canadian Bank a commitment fee on the average daily Unused
Commitment of such Canadian Bank.  In each case payment of commitment fees will
be in respect of the





                                      -43-
<PAGE>   49
relevant Bank's Unused Commitment from the date hereof in the case of each Bank
listed on the signature pages hereof and from the effective date specified in
the Assignment and Acceptance pursuant to which it became a Bank in the case of
each other Bank until the Termination Date, payable quarterly in arrears on the
last day of each March, June, September and December hereafter, commencing June
30, 1997, and on the Termination Date, at a rate per annum equal to the
Applicable Commitment Fee Rate in effect from time to time.

              (b)     Each Borrower agrees to pay to the U.S. Administrative
Agent, for its sole account, such fees as have been agreed to in a separate fee
letter dated October 23, 1996 among the U.S. Administrative Agent and the
Borrowers.  Each Borrower additionally agrees to pay to each Administrative
Agent, for its sole account, such additional fees, if any, as may be agreed to
from time to time by such Borrower and such Administrative Agent, but agreement
to any such additional fees shall be in the sole discretion of each of the
Borrowers and such Administrative Agent.

              (c)     The Borrowers shall have the right, upon at least three
Canadian Business Days' notice to the U.S. Administrative Agent from both
Borrowers, to terminate in whole or reduce in part the Unused Commitments;
provided that (i) each partial reduction shall be in the aggregate amount of
U.S. $5,000,000 or an integral multiple of U.S. $1,000,000 in excess thereof,
and (ii) each termination or partial reduction of the Unused Commitments shall
reduce ratably the Maximum Commitments of (a) the U.S. Banks by an aggregate
amount equal to the amount of such termination or partial reduction, and (b)
the Canadian Banks by an aggregate amount equal to the amount of such
termination or partial reduction.  Any such termination or reduction shall be
permanent.

              (d)     Upon the termination of all the Commitments (other than
pursuant to Section 6.01) and provided that (i) there are no Advances, accrued
interest thereon or fees then outstanding, (ii) all BA Obligations then
outstanding have been cash collateralized in an amount equal to 100% of the
Face Amount of such BA Obligations pursuant to and in accordance with Section
2.09(b)(ii) and Section 5.01(n) (or, if requested by the Required Banks, are
backed by a letter of credit in favor of the Canadian Administrative Agent (for
the ratable benefit of the Canadian Banks) issued by any bank named in Schedule
I to the Bank Act (Canada) in the amount of 100% of the Face Amount of such BA
Obligations), (iii) the Canadian Borrower shall remain liable in respect of
such BA Obligations and (iv) the U.S.  Borrower shall remain liable therefor
under the Guaranty, then this Agreement and the other Loan Documents shall be
terminated (other than Sections 2.11, 2.12, 5.01(n) and 8.04 and any obligation
to pay any





                                      -44-
<PAGE>   50
other amount payable on the date so terminated).

     Section 2.05.    Repayment of Obligations.  (a) The U.S. Borrower shall
repay the principal amount of each U.S. Advance owing to each Bank on March 31,
2002 or on such earlier date as may be applicable pursuant hereto.  The
Canadian Borrower shall repay the principal amount of each Canadian Advance
owing to each Bank on March 31, 2002 or on such earlier date as may be
applicable pursuant hereto.

              (b)     The Canadian Borrower shall, subject to Sections 2.19(a)
and 2.19(b), pay to the Canadian Administrative Agent for the ratable account
of the Canadian Banks on the Maturity Date of any BA Obligations an amount
equal to the sum of (1) the aggregate Face Amount of all such BA Obligations
maturing on such date and (2) the aggregate principal amount of all Canadian
Prime Rate Advances made pursuant to Section 2.03(a) or Section 2.19 in
connection with the Drawing of such BA Obligations.  Any payment by the
Canadian Borrower of any BA Obligations in accordance with this Section 2.05(b)
shall, to the extent of such payment, satisfy the obligations of the Canadian
Borrower under the BA Obligations to which it relates and, in the case of a
Bankers' Acceptance, the Bank that has accepted such Bankers' Acceptance shall,
to the extent of such payment to such Bank, thereafter be solely responsible
for the payment thereof.

              (c)     The Canadian Borrower shall, on each Canadian Business
Day on which notice is given by the U.S. Administrative Agent that a prepayment
under this Section 2.05(c) is required, prepay (ratably among the Canadian
Banks) an aggregate principal amount (or an aggregate Face Amount) of the
Accommodations outstanding to such Borrower comprising part of the same
Borrowings or Drawings, as the case may be, equal to the amount by which (A)
the sum of (x) the aggregate principal amount of the Advances outstanding to
such Borrower plus (y) the aggregate Face Amount of the BA Obligations then
outstanding exceeds (B) the aggregate Commitments of the Canadian Banks on such
Business Day (after giving effect to any permanent reduction thereof on or
prior to such Business Day pursuant to Section 2.04(c) and after giving effect
to any Designation Notice that becomes effective on or prior to such Business
Day).  For purposes of determining the principal amount of any outstanding
Accommodations denominated in Canadian Dollars, such amounts shall be
calculated by the U.S. Administrative Agent (and each such calculation shall be
conclusive for purposes hereof, absent manifest error) on the basis of the U.S.
Dollar Equivalent thereof, and it is expressly understood and agreed that
fluctuations in currency exchange rates will result in mandatory prepayments
hereunder to the extent any such fluctuation results in the aggregate amount of
outstanding Accommodations to the Canadian Borrower





                                      -45-
<PAGE>   51
measured in U.S. Dollars being in excess of the amounts contemplated above
measured in U.S. Dollars.

     Section 2.06.    Interest; Drawing Fees.  (a) The U.S. Borrower shall pay
interest on the unpaid principal amount of each U.S. Advance from the date of
such Advance until such principal amount shall be paid in full, at the
following rates per annum:

                      (i)      During such periods as such Advance is a Base
Rate Advance, a rate per annum equal at all times to the sum of the Base Rate
in effect from time to time plus the Applicable Margin in effect from time to
time for Base Rate Advances, payable quarterly in arrears on the last day of
each March, June, September and December and on the date such Base Rate Advance
shall be Converted or paid in full.

                      (ii)     During such periods as such Advance is a
Eurodollar Rate Advance, a rate per annum equal at all times during each
Interest Period for such Advance to the sum of the Eurodollar Rate for such
Interest Period plus the Applicable Margin in effect from time to time for
Eurodollar Rate Advances, payable on the last day of such Interest Period and,
if such Interest Period has a duration of more than three months, on each day
that occurs during such Interest Period every three months from the first day
of such Interest Period and on the date such Advance shall be Converted or paid
in full.

                      (iii)    During such periods as such Advance is a CD Rate
Advance, a rate per annum equal at all times during each Interest Period for
such Advance to the sum of the Adjusted CD Rate for such Interest Period plus
the Applicable Margin in effect from time to time for Adjusted CD Rate
Advances, payable on the last day of such Interest Period and, if such Interest
Period has a duration of more than 90 days, on each day that occurs during such
Interest Period every 90 days from the first day of such Interest Period and on
the date such Advance shall be Converted or paid in full.

              (b)     The Canadian Borrower shall pay interest on the unpaid
principal amount of each Canadian Advance from the date of such Advance until
such principal amount shall be paid in full, at a rate per annum equal at all
times to the sum of the Canadian Prime Rate in effect from time to time plus
the Applicable Margin in effect from time to time for Canadian Prime Rate
Advances, payable quarterly in arrears on the last day of each March, June,
September and December and on the date such Canadian Prime Rate Advance shall
be Converted or paid in full.

              (c)     The U.S. Borrower shall pay interest, to the fullest
extent permitted





                                      -46-
<PAGE>   52
by law, on the amount of any interest, fee, cost or other obligation (other
than principal of Advances) payable hereunder by it that is not paid when due,
from the date such amount shall be due until such amount shall be paid in full,
payable in arrears on the date such amount shall be paid in full and on demand,
at a rate per annum equal at all times to the sum of the Base Rate in effect
from time to time plus 2% per annum.  The Canadian Borrower shall pay interest,
to the fullest extent permitted by law, on the amount of any interest, fee,
cost or other obligation (other than principal of Advances) payable hereunder
by it that is not paid when due, from the date such amount shall be due until
such amount shall be paid in full, payable in arrears on the date such amount
shall be paid in full and on demand, at a rate per annum equal at all times to
the sum of the Canadian Prime Rate in effect from time to time plus 2% per
annum.

              (d)     The Canadian Borrower shall, on the date of each Drawing
of, on the date of any Conversion into, and on the date of each renewal of any
outstanding, BA Obligations, pay to the Canadian Administrative Agent, in
Canadian Dollars, for the ratable account of the Canadian Banks accepting
Drafts and purchasing Bankers' Acceptances or BA Equivalent Notes, the Drawing
Fee with respect to such BA Obligations.  The Canadian Borrower irrevocably
authorizes each such Bank to deduct the Drawing Fee payable with respect to
each BA Obligation of such Bank from the Drawing Purchase Price payable by such
Bank in respect of such BA Obligation in accordance with Section 2.03 and to
apply such amount so withheld to the payment of such Drawing Fee for the
account of the Canadian Borrower and, to the extent such Drawing Fee is so
withheld and legally permitted to be so applied, the Canadian Borrower's
obligations under the preceding sentence in respect of such Drawing Fee shall
be satisfied.

     Section 2.07.    Additional Interest on Eurodollar Rate Advances.  The
Borrower shall pay to each Bank, so long as such Bank shall be required under
regulations of the Federal Reserve Board to maintain reserves with respect to
liabilities or assets consisting of or including Eurocurrency Liabilities,
additional interest on the unpaid principal amount of each Advance of such Bank
during such periods as such Advance is a Eurodollar Rate Advance, from the date
of such Advance until such principal amount is paid in full, at an interest
rate per annum equal at all times to the remainder obtained by subtracting (i)
the Eurodollar Rate for such Interest Period for such Eurodollar Rate Advance
from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage
(expressed as a decimal) equal to 100% minus the Eurodollar Rate Reserve
Percentage of such Bank for such Interest Period, payable on each date on which
interest is payable on such Eurodollar Rate Advance.  Such additional interest
shall be determined by such Bank and notified to the Borrower through the U.S.
Administrative Agent.

     Section 2.08.    Interest Rate Determination.  (a) Each U.S. Reference
Bank agrees to make reasonable efforts to furnish to the U.S. Administrative
Agent timely information for the purpose of determining each Eurodollar Rate
and each Adjusted CD Rate.  Each Canadian Reference Bank agrees to make
reasonable efforts to furnish to the Canadian Administrative Agent timely
information for the purpose of determining each Bankers' Acceptance Rate.  If
any of the Reference Banks shall not furnish such timely information to the
appropriate Administrative Agent for the purpose of determining any such
interest rate, such Administrative Agent shall determine such interest rate on
the basis of timely information furnished by the remaining Reference Bank.  The
U.S. Administrative Agent shall give prompt notice to the U.S. Borrower and the
U.S. Banks of the applicable interest rate determined by the U.S.
Administrative Agent for purposes of Section 2.06(a)(ii) or (a)(iii) and the
rate, if any, furnished by each U.S. Reference Bank for the purpose of
determining the interest rate under Section 2.06(a)(ii) or (a)(iii).  The
Canadian Administrative Agent shall give prompt notice to the Canadian Borrower
and the Canadian Banks of each Bankers' Acceptance Rate determined by such
Administrative Agent for purposes hereof and the rate, if any, furnished by
each Reference Bank for the purpose of determining such Bankers' Acceptance
Rate.

              (b)     If none of the U.S. Reference Banks furnishes timely
information to the U.S. Administrative Agent for determining the Eurodollar
Rate or Adjusted CD Rate for any Eurodollar Rate Advances or CD Rate Advances,
as the case may be:

                      (i)      the U.S. Administrative Agent shall forthwith
     notify the U.S. Borrower and the U.S. Banks that the interest rate cannot
     be determined for such Eurodollar Rate Advances or CD Rate Advances, as
     the case may be,

                      (ii)     each such Eurodollar Rate Advance or CD Rate
     Advance, as the case may be, will automatically, on the last day of the
     then existing Interest Period therefor, Convert into a Base Rate Advance
     (or if such Advance is then a Base Rate Advance, will continue as a Base
     Rate Advance, unless it shall be Converted in accordance with Section 2.15
     to the other U.S. Type of Advance as to which the interest rate can be
     determined), and

                      (iii)    the obligation of the U.S. Banks to make
     Eurodollar Rate Advances or CD Rate Advances, as the case may be, or to
     Convert Advances into Eurodollar Rate Advances or CD Rate Advances, as the
     case may be, shall be suspended until the U.S. Administrative Agent shall
     notify the U.S. Borrower and the U.S. Banks that the circumstances causing
     such suspension no longer exist

     (which the U.S. Administrative Agent agrees to do promptly following its
     becoming aware that such circumstances no longer exist).

              (c)     If none of the Canadian Reference Banks furnishes timely
information to the Canadian Administrative Agent for determining the Bankers'
Acceptance Rate for any BA Obligations:

                      (i)      the Canadian Administrative Agent shall
     forthwith notify the Canadian Borrower and the Canadian Banks that the
     interest rate cannot be determined for such BA Obligations, and

                      (ii)     the obligation of the Canadian Banks to
     complete and accept Drafts and/or to purchase Bankers' Acceptances or BA
     Equivalent Notes, or to Convert Canadian Prime Rate Advances into BA
     Obligations, as the case may be, shall be suspended until the Canadian
     Administrative Agent shall notify the Canadian Borrower and the Canadian
     Banks that the circumstances causing such suspension no longer exist
     (which the Canadian Administrative Agent agrees to do promptly following
     its becoming aware that such circumstances no longer exist).

              (d)      If, with respect to any Eurodollar Rate Advances, the
Required Banks notify the U.S. Administrative Agent (A) that the Eurodollar
Rate for any Interest Period for such Advances will not adequately reflect the
cost to such Required Banks of making, funding or maintaining their respective
Eurodollar Rate Advances for such Interest Period or (B) that U.S. Dollar
deposits for the relevant amounts and Interest Period for their respective
Advances are not available to them in the London interbank market, the U.S.
Administrative Agent shall forthwith so notify the U.S. Borrower and the U.S.
Banks, whereupon

                      (i)      each Eurodollar Rate Advance will automatically,
     on the last day of the then existing Interest Period therefor, Convert
     into a Base Rate Advance (or will Convert into a CD Rate Advance if such
     Conversion has been requested in accordance with Section 2.15), and

                      (ii)     the obligation of the Banks to make, or to
     Convert Advances into, Eurodollar Rate Advances shall be suspended until
     the U.S. Administrative Agent shall notify the U.S. Borrower and the U.S.
     Banks that the circumstances causing such suspension no longer exist
     (which the U.S. Administrative Agent agrees to do promptly following its
     becoming aware that





                                      -49-
<PAGE>   55
     such circumstances no longer exist).

              (e)     If the U.S. Borrower shall fail to select the duration of
any Interest Period for any Eurodollar Rate Advances or CD Rate Advances in
accordance with the provisions contained in the definition of "Interest Period"
in Section 1.01, the U.S. Administrative Agent will forthwith so notify the
U.S. Borrower and the U.S. Banks and such Advances will automatically, on the
last day of the then existing Interest Period therefor, Convert into Base Rate
Advances (or if such Advances are then Base Rate Advances, will continue as
Base Rate Advances).

              (f)     On the date on which the aggregate unpaid principal
amount of Eurodollar Rate Advances or CD Rate Advances having the same Interest
Period (whether comprising one or more Borrowings) shall be reduced, by payment
or prepayment or otherwise, to less than U.S. $10,000,000, such Advances shall
automatically Convert into Base Rate Advances, and on and after such date the
right of the U.S. Borrower to Convert such Advances into Eurodollar Rate
Advances or CD Rate Advances, as the case may be, shall terminate, unless when
combined with other Base Rate Advances such Conversion meets the requirements
of Section 2.15.

              (g)     Upon the occurrence and during the continuance of any
Event of Default under Section 6.01(a) or Section 6.01(e), (i) each Eurodollar
Rate Advance and each CD Rate Advance will automatically, on the last day of
the then existing Interest Period therefor, Convert into a Base Rate Advance,
and (ii) the obligation of the Banks to make, or to Convert Advances into,
Eurodollar Rate Advances or CD Rate Advances shall be suspended.

     Section 2.09.    Optional Prepayments.  (a) Neither Borrower shall have
any right to prepay (other than prepayments required herein) any principal
amount of any Advance other than as provided in this Section 2.09.  The U.S.
Borrower may, upon notice given to the U.S. Administrative Agent before 11:00
A.M. (New York City time) on the first Business Day prior to the date of
prepayment in the case of Base Rate Advances or upon at least three Business
Days' notice to the U.S. Administrative Agent in the case of Eurodollar Rate
Advances or CD Rate Advances, in each case stating the proposed date (which
shall be a Business Day) and aggregate principal amount of the prepayment, and
if such notice is given the U.S. Borrower shall, prepay the outstanding
principal amounts of the Advances comprising part of the same U.S. Borrowing in
whole or ratably in part, together with accrued interest to the date of such
prepayment on the principal amount prepaid; provided that (x) each partial
prepayment shall be in an aggregate principal amount of U.S. $5,000,000 (or, in
the case of a partial prepayment of a Borrowing





                                      -50-
<PAGE>   56
comprised of Base Rate Advances, U.S. $1,000,000) or an integral multiple of
U.S. $1,000,000 in excess thereof, and after giving effect thereto no U.S.
Borrowing then outstanding shall have a principal amount of less than U.S.
$10,000,000 (or, in the case of a Borrowing comprised of Base Rate Advances,
U.S. $1,000,000); and (y) in the case of any such prepayment of a Eurodollar
Rate Advance or a CD Rate Advance, the U.S. Borrower shall be obligated to
reimburse the Banks in respect thereof pursuant to Section 8.04(b).  The
Canadian Borrower may, upon notice given to the Canadian Administrative Agent
before 11:00 A.M. (New York City time) on the first Business Day prior to the
date of prepayment stating the proposed date (which shall be a Business Day)
and aggregate principal amount of the prepayment, and if such notice is given
the Canadian Borrower shall, prepay the outstanding principal amounts of the
Advances comprising part of the same Canadian Borrowing in whole or ratably in
part or the Canadian Prime Rate Advances made pursuant to Section 2.03 or
Section 2.19 in whole, in each case together with accrued interest to the date
of such prepayment on the principal amount prepaid; provided that, except in
the case of prepayments of the Canadian Prime Rate Advances made on any date
pursuant to Section 2.03 or Section 2.19, each partial prepayment shall be in
an aggregate principal amount of C$1,000,000 (calculated upon the exchange rate
in effect on the last day the Agent could have received an effective notice
applicable thereto) or, except in connection with a reduction of the
Commitments under Section 2.04 or redesignation under Section 2.16, an integral
multiple of C$100,000 in excess thereof; provided, further, that, after giving
effect thereto no Canadian Borrowing then outstanding shall have a principal
amount of less than C$1,000,000.  BA Obligations may not be prepaid at any time
except as required by Section 2.05.

     (b)      Each prepayment pursuant to Section 2.09(a) or Section 2.05(c)
shall be allocated to the Advances or BA Obligations outstanding to the
Borrower making such prepayment and shall be applied to such Advances or BA
Obligations as directed by such Borrower so long as no Event of Default has
occurred and is continuing on the date of such prepayment and, if an Event of
Default has occurred and is continuing or such Borrower has not specified the
application of any such prepayment, shall be applied:

              (i)     in the case of Advances outstanding to the U.S. Borrower,
     to prepay (ratably among the Banks holding such Advances) U.S. Borrower
     Advances then outstanding comprising part of the same Borrowings until
     such Advances are paid in full; and

              (ii)    in the case of Advances outstanding to the Canadian
     Borrower or BA Obligations, first to prepay (ratably among the Banks
     holding such Advances)





                                      -51-
<PAGE>   57
     Canadian Advances then outstanding comprising part of the same Borrowings
     until such Advances are paid in full, and second deposited in the Canadian
     Cash Collateral Account to cash collateralize 100% of the Face Amount of
     all BA Obligations then outstanding.  Upon the Maturity Date of any BA
     Obligation, for which funds are on deposit in the Canadian Cash Collateral
     Account, such funds shall be applied to reimburse the relevant Canadian
     Banks.

     (c)      Any prepayment by the Canadian Borrower of any BA Obligations in
accordance with this Section 2.09 shall, upon the application thereof at the
applicable Maturity Date therefor, satisfy, to the extent of such application,
the obligations of the Canadian Borrower under such BA Obligations to which it
relates and, in the case of a Bankers' Acceptance, the Bank that has accepted
such Bankers' Acceptance shall thereafter, to the extent of such application,
be solely responsible for the payment thereof.

     (d)      All prepayments under this Section 2.09 shall be made together
with accrued interest to the date of such prepayment on the principal amount
prepaid.  If any payment made under this Section 2.09 on account of Eurodollar
Rate Advances, CD Rate Advances or BA Obligations is made other than on the
last day of the applicable Interest Period or Maturity Date therefor, as the
case may be, the relevant Borrower shall also pay any amounts owing pursuant to
Section 8.04(b).

     Section 2.10.    Payments and Computations.  (a)  Each Borrower shall make
each payment hereunder and under the Notes not later than 12:00 noon (New York
City time) on the day when due to the U.S. Administrative Agent (except that
(1) payments under Section 2.07 shall be paid directly to the Bank entitled
thereto and (2) payments by the Canadian Borrower shall be made to the Canadian
Administrative Agent at its address referred to in Section 8.02) at its address
referred to in Section 8.02 in same day funds (i) in the case of all payments
in respect of any BA Obligation or of principal of or interest on Canadian
Advances, in Canadian Dollars and (ii) in the case of all payments of principal
of and interest on U.S. Advances, fees, expenses, indemnities and other amounts
(except principal of and interest on Canadian Advances), in U.S. Dollars.  The
appropriate Administrative Agent will promptly thereafter cause to be
distributed like funds relating to the payment of principal, interest or
commitment fees ratably (except amounts payable pursuant to Section 2.11,
Section 2.12 or Section 8.04(b) and except that any Bank may receive less than
its ratable share of interest to the extent Section 8.06 is applicable to it)
to the Banks for the account of their respective Applicable Lending Offices,
and like funds relating to the payment of any other amount payable to any Bank
to such Bank for the account of its Applicable Lending Office, in each case to
be applied in accordance with the terms of this Agreement.  Upon acceptance by
the





                                      -52-
<PAGE>   58
U.S. Administrative Agent of an Assignment and Acceptance and recording of the
information contained therein in the Register pursuant to Section 8.08(d), from
and after the effective date specified in such Assignment and Acceptance, the
appropriate Administrative Agent shall make all payments hereunder and under
the Notes in respect of the interest assigned thereby to the Bank assignee
thereunder, and the parties to such Assignment and Acceptance shall make all
appropriate adjustments in such payments for periods prior to such effective
date directly between themselves.  At the time of each payment by a Borrower in
respect of a BA Obligation or of any principal of or interest on any Borrowing
to either Administrative Agent, such Borrower shall notify such Administrative
Agent of the BA Obligation or Borrowing, as the case may be, to which such
payment shall apply, subject to Section 2.09(b).  In the absence of such notice
such Administrative Agent may specify the BA Obligation or Borrowing to which
such payment shall apply in accordance with Section 2.09(b).

              (b)     All computations of interest based on the Base Rate
(except during such times as the Base Rate is determined pursuant to clause (b)
of the definition thereof) and of commitment fees shall be made by the U.S.
Administrative Agent on the basis of a year of 365 or 366 days, as the case may
be, and all computations of interest based on the Eurodollar Rate, Adjusted CD
Rate, the Federal Funds Rate or, during such times as the Base Rate is
determined pursuant to clause (b) of the definition thereof, the Base Rate
shall be made by the U.S. Administrative Agent, and all computations of
interest pursuant to Section 2.07 shall be made by a Bank, on the basis of a
year of 360 days, in each case for the actual number of days (including the
first day but excluding the last day) occurring in the period for which such
interest or fees are payable. All computations of interest based on the
Canadian Prime Rate shall be made by the Canadian Administrative Agent on the
basis of a year of 365 or 366 days, as the case may be, in each case for the
actual number of days (including the first day but excluding the last day)
occurring in the period for which such interest or fees are payable. Each
determination by either Administrative Agent (or in the case of Section 2.07,
by a Bank) of an interest rate hereunder shall be conclusive and binding for
all purposes, absent manifest error.

              (c)     Whenever any payment hereunder (other than in respect of
BA Obligations or principal of or interest on the Canadian Advances) or under
the U.S. Notes shall be stated to be due on a day other than a U.S. Business
Day, such payment shall be made on the next succeeding U.S. Business Day, and
such extension of time shall in such case be included in the computation of
payment of interest and fees, as the case may be; provided, however, if such
extension would cause payment in respect of interest on or principal of
Eurodollar Rate Advances or CD Rate Advances to be made in the next following
calendar month, such payment shall be made on the next preceding





                                      -53-
<PAGE>   59
U.S. Business Day.  Whenever any payment in respect of BA Obligations or
principal of or interest on Canadian Advances shall be stated to be due on a
day other than a Canadian Business Day, such payment shall be made on the next
succeeding Canadian Business Day, and such extension of time shall in such case
be included in the computation of payment of interest on Canadian
Accommodations.

              (d)     Unless the appropriate Administrative Agent shall have
received notice from a Borrower prior to the date on which any payment is due
to the Banks hereunder that such Borrower will not make such payment in full to
the appropriate Administrative Agent, such Administrative Agent may assume that
such Borrower has made such payment in full to such Administrative Agent on
such date and such Administrative Agent may, in reliance upon such assumption,
cause to be distributed to each Bank on such due date an amount equal to the
amount then due such Bank.  If and to the extent that such Borrower shall not
have so made such payment in full to such Administrative Agent, each Bank shall
repay to such Administrative Agent forthwith on demand such amount distributed
to such Bank together with interest thereon, for each day from the date such
amount is distributed to such Bank until the date such Bank repays such amount
to such Administrative Agent, (i) at the Canadian Interbank Rate in the case of
payments which are due in Canadian Dollars, and (ii) otherwise at the Federal
Funds Rate.

              (e)     Each Borrower hereby authorizes each Bank, if and to the
extent payment owed to such Bank by such Borrower is not made when due
hereunder or under the Note held by each Bank, to charge from time to time
against any or all of such Borrower's accounts with such Bank any amount so
due.

              (f)     For purposes of the Interest Act (Canada), the principle
of deemed reinvestment of interest shall not apply to any interest calculation
under this Agreement in respect of Accommodations to the Canadian Borrower and
the rates of interest stipulated in this Agreement in respect of Accommodations
to the Canadian Borrower are intended to be normal and not effective rates or
yields.

     Section 2.11.    Increased Costs and Capital Requirements.  (a)  If, due
to either (i) the introduction of or any change in, or in the interpretation
(by any central bank or comparable agency or governmental authority charged
with the interpretation or administration thereof) of, any law or regulation or
(ii) the compliance with any guideline issued after the date hereof or request
made after the date hereof, in each case in this clause (ii) from any central
bank or other governmental authority (whether or not having the force of law),
there shall be any increase in the cost to any U.S. Bank of agreeing to





                                      -54-
<PAGE>   60
make or making, funding or maintaining any Eurodollar Rate Advance or CD Rate
Advance or any reduction of any amount received or receivable by any Bank under
any of the Loan Documents as a result of agreeing to make or making, funding or
maintaining any Eurodollar Rate Advance or any CD Rate Advance (excluding for
purposes of this Section 2.11(a) any such increased costs resulting from (A)
Taxes or Other Taxes (as to which Section 2.12 shall govern) or any change in
the Eurodollar Rate Reserve Percentage reflected in the interest charged under
Section 2.07 and (B) Excluded Taxes), then the U.S. Borrower shall from time to
time, promptly after its receipt of notice from such Bank (with a copy of such
notice delivered by such Bank to the U.S. Administrative Agent), pay to the
U.S. Administrative Agent for the account of such Bank additional amounts
sufficient to compensate such Bank for such increased cost or reduction.  A
certificate as to the basis and the amount of such increased cost or reduction,
submitted to the U.S. Borrower and the U.S. Administrative Agent by such Bank,
shall be conclusive and binding for all purposes, absent manifest error,
provided that the determination thereof is made on a reasonable basis.

              (b)     If, due to either (i) the introduction of or any change
in, or in the interpretation (by any central bank or comparable agency or
governmental authority charged with the interpretation or administration
thereof) of, any law or regulation or (ii) the compliance with any guideline
issued after the date hereof or request made after the date hereof, in each
case in this clause (ii) from any central bank or other governmental authority
(whether or not having the force of law), there shall be any increase in the
cost to any Canadian Bank of agreeing to perform or of performing its
obligations under this Agreement under or in respect of any BA Obligations or
any reduction in any amount payable to, or any increase in any payment required
to be made by, or any forgiveness or reduction of effective return to such Bank
under or in respect of any BA Obligations (excluding for purposes of this
Section 2.11(b) any such increased costs resulting from (A) Taxes or Other
Taxes (as to which Section 2.12 shall govern) and (B) Excluded Taxes), then the
Canadian Borrower shall from time to time, promptly after its receipt of notice
from such Bank (with a copy of such notice delivered by such Bank to the
Canadian Administrative Agent), pay to the Canadian Administrative Agent for
the account of such Bank additional amounts sufficient to compensate such Bank
for such increased cost, reduction or other matter referred to in this Section
2.11(b).  A certificate as to the basis and the amount of such increased cost,
reduction or other such matter, submitted to the Canadian Borrower and the
Canadian Administrative Agent by such Bank, shall be conclusive and binding for
all purposes, absent manifest error, provided that the determination thereof is
made on a reasonable basis.

            (c)     If any Bank determines that compliance by such Bank with any





                                      -55-
<PAGE>   61
law or regulation adopted after the date hereof, any change after the date
hereof in any law or regulation, any guideline issued after the date hereof
from any central bank or other governmental authority (whether or not having
the force of law) or any request made after the date hereof from any central
bank or other governmental authority (whether or not having the force of law)
increases or would increase the amount of capital required or expected to be
maintained by such Bank or any Person controlling such Bank and that the amount
of such capital is increased by or based upon the existence of such Bank's
commitment to lend or to accept, purchase and/or discount BA Obligations
hereunder and other commitments of this type or the purchase, acceptance or
maintenance of BA Obligations, then, promptly following its receipt of notice
from such Bank (with a copy of such notice delivered to such Bank to the
Administrative Agents), the Borrowers shall pay to the U.S. Administrative
Agent for the account of such Bank, from time to time as specified by such
Bank, additional amounts sufficient to compensate such Bank or such Person in
the light of such circumstances (excluding amounts resulting from (A) Taxes or
Other Taxes (as to which Section 2.12 shall govern) or any change in the
Eurodollar Rate Reserve Percentage reflected in the interest charged under
Section 2.07 and (B) Excluded Taxes), to the extent that such Bank reasonably
determines such increase in capital to be allocable to the existence of such
Bank's commitment to lend or to accept, purchase and/or discount BA Obligations
hereunder or the purchase, acceptance or maintenance of BA Obligations.  A
certificate as to such amounts submitted to the Borrowers and the U.S.
Administrative Agent by such Bank shall be conclusive and binding for all
purposes, absent manifest error, provided that the determination thereof is
made on a reasonable basis.

              (d)     Neither Borrower shall be required to pay any Bank any
amount otherwise owed under this Section 2.11 that is incurred more than 90
days prior to notice thereof being given by such Bank to such Borrower, unless
such amount had not been imposed or was not determinable on the date that is 90
days prior to such notice.

     Section 2.12.    Taxes.  (a)  Any and all payments by either Borrower
hereunder, under the Guaranty or under the Notes or in respect of any BA
Obligation shall be made, in accordance with Section 2.10, free and clear of
and without deduction for any and all present or future taxes, levies, imposts,
deductions, charges and withholdings, and all liabilities with respect thereto,
excluding, in the case of each Bank and each Administrative Agent, Excluded
Taxes (all such taxes, levies, imposts, deductions, charges, withholdings and
liabilities other than Excluded Taxes being hereinafter referred to (subject to
further exclusions, if any, under Section 2.12(e)) as "Taxes").  If any Taxes
are required to be withheld or deducted by any Person from or in respect of any
sum payable hereunder or under any Note or in respect of any BA Obligation to
any Bank or any Administrative





                                      -56-
<PAGE>   62
Agent, (i) the sum payable by the relevant Borrower shall be increased as may
be necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.12) such Bank or
such Administrative Agent (as the case may be) receives an amount equal to the
sum it would have received had no such deductions been made, (ii) the relevant
Borrower shall make such deductions and (iii) the relevant Borrower shall pay
the full amount deducted to the relevant taxation authority or other authority
in accordance with applicable law.  Any such payment by a Borrower shall be
made in the name of the relevant Bank or Administrative Agent (as the case may
be).

     (b)      In addition, each Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made by it or receipt from it
hereunder, under the Guaranty or under the Notes or in respect of any BA
Obligation or from its execution, delivery or registration of, performing
under, or otherwise with respect to, this Agreement, any BA Obligation, the
Guaranty or any of the Notes (herein referred to as "Other Taxes").

     (c)      The Borrowers will indemnify each Bank and each Administrative
Agent for the full amount of Taxes and Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts
payable under this Section 2.12) imposed on or paid by such Bank or such
Administrative Agent (as the case may be) and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted,
but excluding penalties, interest, expenses and other liabilities arising as a
result of the gross negligence or willful misconduct of such Bank or such
Administrative Agent (as the case may be).  Payments under any indemnification
provided for in this Section 2.12(c) shall be made within 30 days from the date
such Bank or such Administrative Agent (as the case may be) makes written
demand therefor, which demand shall state the basis for, and set forth the
calculation of the amount of, such demand.

     (d)      Within 30 days after the date of any payment of Taxes, the
Borrower making such payment will furnish to the U.S. Administrative Agent, at
its address referred to in Section 8.02, the original or a certified copy of a
receipt evidencing payment thereof. In the case of any payment hereunder, under
the Guaranty or under the Notes by or on behalf of the U.S. Borrower through an
account or branch outside the United States or by or on behalf of the U.S.
Borrower by a payor that is not a United States person, if the U.S. Borrower
determines that no Taxes are payable in respect thereof, the U.S. Borrower
shall furnish, or shall cause such payor to furnish, to each Administrative
Agent a written statement from each appropriate taxing authority or an





                                      -57-
<PAGE>   63
opinion of counsel acceptable to the Administrative Agents, in either case
stating that such payment is exempt from or not subject to Taxes.  In the case
of any payment hereunder, under the Guaranty or under the Notes or in respect
of BA Obligations by or on behalf of the Canadian Borrower through an account
or branch outside Canada or by or on behalf of the Canadian Borrower by a payor
that is not a Resident in Canada, if the Canadian Borrower determines that no
Taxes are payable in respect thereof, the Canadian Borrower shall furnish, or
shall cause such payor to furnish, to each Administrative Agent a written
statement from each appropriate taxing authority or an opinion of counsel
acceptable to the Administrative Agents, in either case stating that such
payment is exempt from or not subject to Taxes.  For purposes of this Section
2.12(d) and Section 2.12(e), the terms "United States" and "United States
person" shall have the meanings specified in Section 7701 of the Code, and the
terms "Canada" and "Resident in Canada" shall have the meanings they have for
the purposes of the Income Tax Act (Canada).

     (e)      Each U.S. Bank that is not a citizen or resident of the United
States, a corporation, partnership, or other entity created or organized in or
under the laws of the United States or any state thereof, or an estate or trust
that is subject to federal income taxation regardless of source of its income,
on or prior to the date of its execution and delivery of this Agreement in the
case of each such Bank listed on the signature pages hereof and not later than
the date of the Assignment and Acceptance pursuant to which it becomes a Bank
in the case of each other such U.S. Bank, and from time to time thereafter as
requested in writing by the U.S. Borrower or the U.S. Administrative Agent (but
only so long as such Bank remains lawfully able to do so), shall provide each
of the U.S. Administrative Agent and the U.S. Borrower with two original
Internal Revenue Service Forms 1001 or 4224, as appropriate, or any successor
or other form prescribed by the Internal Revenue Service, or, in the case of a
U.S. Bank claiming exemption from U.S. federal withholding tax under Section
871(h) or 881(c) of the Code with respect to payments of "portfolio interest",
a Form W-8, or any successor or other form prescribed by the Code (and, if such
Bank delivers a Form W-8, an annual certificate representing that (i) such Bank
is not a "bank" for purposes of Section 881(c) of the Code (and is not subject
to regulatory or other legal requirements as a bank in any jurisdiction, and
has not been treated as a bank in any filing with or submission made to any
government or rating agency), (ii) is not a 10-percent shareholder (within the
meaning of Section 871(h)(3)(B) of the Code) of the U.S. Borrower and (iii) is
not a controlled foreign corporation related to the U.S. Borrower (within the
meaning of Section 864(d)(4) of the Code)), along with such other additional
forms or certificates as the U.S. Borrower or the U.S. Administrative Agent may
reasonably request, certifying that such Bank is exempt from or entitled to a
reduced rate of United States withholding tax on payments pursuant





                                      -58-
<PAGE>   64
to this Agreement or the Notes.  If such forms provided by a Bank at the time
such Bank first becomes a party to this Agreement indicate a United States
interest withholding tax rate in excess of zero, withholding tax at such rate
shall be considered excluded from Taxes unless and until such Bank provides the
appropriate forms certifying that a lesser rate applies, whereupon withholding
tax at such lesser rate only shall be considered excluded from Taxes for
periods governed by such form; provided that if at the date of the Assignment
and Acceptance pursuant to which a U.S. Bank assignee becomes a party to this
Agreement (other than by virtue of an assignment under Section 2.17), the U.S.
Bank assignor was entitled to payments under Section 2.12(a) in respect of
United States withholding tax with respect to interest paid at such date, then
to such extent, the term Taxes shall include (in addition to withholding taxes
that may be imposed in the future and not otherwise excluded above or other
amounts otherwise includable in Taxes) United States withholding tax, if any,
applicable with respect to the Bank assignee on such date.  Each U.S. Bank that
is subject to the requirements of this Section 2.12(e) and which so delivers a
Form 1001, 4224 or W-8 required by this Section 2.12(e) further undertakes to
deliver (but only so long as such Bank remains lawfully able to do so) to the
U.S. Borrower and the U.S. Administrative Agent two additional copies of such
form (or a successor form) on or before the date such form expires or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent form so delivered by it, and such amendments thereto or extensions or
renewals thereof as may be reasonably requested by the U.S. Borrower or the
U.S. Administrative Agent, in each case certifying that such U.S. Bank is
entitled to receive payments from the U.S. Borrower under any Loan Document
without deduction or withholding of any U.S. federal income taxes, unless an
event (including any change in law or regulation) has occurred prior to the
date on which any such delivery would otherwise be required which renders all
such forms inapplicable or which would prevent such Bank from duly completing
and delivering any such form with respect to it and such Bank advises the U.S.
Borrower and the U.S. Administrative Agent that it is not capable of receiving
such payments without any deduction or withholding of U.S. federal income tax.
If any form or document referred to in this Section 2.12(e) requires the
disclosure of information, other than information necessary to compute the tax
payable and information required on the date hereof by Internal Revenue Service
form 1001 or 4224, that the Bank providing such form or document reasonably
considers to be confidential, such Bank shall give notice thereof to the U.S.
Borrower and shall not be obligated to include in such form or document such
confidential information, but if failure to include such confidential
information in such form or document renders such form or document ineffective
for its purpose, then such Bank shall not be entitled to reimbursement for any
increase in Taxes to the extent caused by or resulting from such
ineffectiveness.

     (f)      For any period with respect to which a U.S. Bank has failed to
provide the U.S. Borrower and the U.S. Administrative Agent with the
appropriate form or certificate (or failed to provide substantially all of the
information required by such form or certificate) required by Section 2.12(e),
such Bank shall not be entitled to indemnification under Section 2.12(a) or (c)
with respect to Taxes imposed by the United States by reason of such failure or
such notification; provided that should a Bank become subject to Taxes because
of its failure to deliver a form required hereunder, the Borrowers shall take
such steps as the Bank shall reasonably request to assist the Bank to recover
such Taxes.

     (g)      Any Bank claiming any additional amounts payable pursuant to this
Section 2.12 agrees to use reasonable efforts (consistent with legal and
regulatory restrictions) to change the jurisdiction of its Eurodollar Lending
Office if the making of such a change would avoid the need for, or reduce the
amount of, any such additional amounts that may thereafter accrue and would
not, in the reasonable judgment of such Bank, be otherwise disadvantageous to
such Bank.  Nothing herein contained shall interfere with the right of each
Bank to arrange its tax affairs in whatever manner it thinks fit nor oblige any
Bank to disclose any information relating to its tax affairs or any
computations in respect thereof, except as set forth in the last sentence of
Section 2.12(c).  Nothing herein contained shall require any Bank to do
anything that would prejudice its ability to benefit from any credits, reliefs,
remissions or repayments to which it may be entitled.

     (h)      The agreements in this Section 2.12 shall survive the termination
of this Agreement and the payment of the Notes and all other amounts payable
hereunder.

     (i)      Should any Bank or Administrative Agent ever receive any refund,
credit or deduction from any taxing authority to which such Bank or
Administrative Agent, as the case may be, would not be entitled but for the
payment by a Borrower of Taxes as required by this Section 2.12 (it being
understood that the decision as to whether or not to claim, and if claimed, as
to the amount of any such refund, credit or deduction shall be made by such
Bank or Administrative Agent, as the case may be, in its sole discretion), such
Bank or Administrative Agent, as the case may be, thereupon shall repay to such
Borrower an amount with respect to such refund, credit or deduction equal to
any net reduction in taxes actually obtained by such Bank or Administrative
Agent, as the case may be, and determined by such Bank or Administrative Agent,
as the case may be, to be directly attributable to such refund, credit or
deduction.

     Section 2.13.    Sharing of Payments, Etc.  If any U.S. Bank shall obtain
any payment (whether voluntary, involuntary, through the exercise of any right
of set-off, or





                                      -60-
<PAGE>   66
otherwise) on account of the principal of or interest on the U.S. Advances
owing to it (except amounts payable pursuant to Sections 2.07, 2.11 or 2.12,
and except that any Bank may receive less than its ratable share of interest to
the extent Section 8.06 is applicable to it) in excess of its ratable share of
payments on account of the principal of or interest on the U.S. Advances
obtained by all the U.S. Banks, such Bank shall forthwith purchase from the
other U.S. Banks such participations in the Advances owing to them as shall be
necessary to cause such purchasing Bank to share the excess payment ratably
with each of them, provided that if all or any portion of such excess payment
is thereafter recovered from such purchasing Bank, such purchase from each Bank
shall be rescinded and such Bank shall repay to the purchasing Bank the
purchase price to the extent of such Bank's ratable share (according to the
proportion of (i) the amount of the participation purchased from such Bank as a
result of such excess payment to (ii) the total amount of such excess payment)
of such recovery together with an amount equal to such Bank's ratable share
(according to the proportion of (i) the amount of such Bank's required
repayment to (ii) the total amount so recovered from the purchasing Bank) of
any interest or other amount paid or payable by the purchasing Bank in respect
of the total amount so recovered.  If any Canadian Bank shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the principal of or interest on the
Advances owing to it or on account of BA Obligations (except amounts payable
pursuant to Sections 2.07, 2.11 or 2.12, and except that any Bank may receive
less than its ratable share of interest to the extent Section 8.06 is
applicable to it) in excess of its ratable share of payments on account of the
principal of or interest on the Canadian Advances or BA Obligations, as the
case may be, obtained by all the Canadian Banks, such Bank shall forthwith
purchase from the other Canadian Banks such participations in the Advances
owing to them or BA Obligations, as the case may be, as shall be necessary to
cause such purchasing Bank to share the excess payment ratably with each of
them, provided that if all or any portion of such excess payment is thereafter
recovered from such purchasing Bank, such purchase from each Bank shall be
rescinded and such Bank shall repay to the purchasing Bank the purchase price
to the extent of such Bank's ratable share (according to the proportion of (i)
the amount of the participation purchased from such Bank as a result of such
excess payment to (ii) the total amount of such excess payment) of such
recovery together with an amount equal to such Bank's ratable share (according
to the proportion of (i) the amount of such Bank's required repayment to (ii)
the total amount so recovered from the purchasing Bank) of any interest or
other amount paid or payable by the purchasing Bank in respect of the total
amount so recovered.  Each Borrower agrees that any Bank so purchasing a
participation from another Bank pursuant to this Section 2.13 may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of set-off) with respect to such participation as fully as if such
Bank were the direct creditor





                                      -61-
<PAGE>   67
of such Borrower in the amount of such participation.

     Section 2.14.    Illegality.  (a)  Notwithstanding any other provision of
this Agreement, if any Bank ("Affected Bank") shall notify the U.S.
Administrative Agent that any law or regulation makes it unlawful, or any
central bank or other governmental authority hereafter asserts that it is
unlawful, for such Affected Bank or its Eurodollar Lending Office to perform
its obligations hereunder to make Eurodollar Rate Advances or to fund or
maintain Eurodollar Rate Advances hereunder, (i) the obligation of such
Affected Bank to make, or to Convert Advances into, Eurodollar Rate Advances
shall be suspended (and any request by the U.S. Borrower for a Borrowing
comprised of Eurodollar Rate Advances shall be deemed a request for a Base Rate
Advance from such Affected Bank to be made on the same date as the Eurodollar
Rate Advances of the Banks that are not Affected Banks and such Base Rate
Advances shall be considered as part of such Borrowing) until such Affected
Bank shall notify the U.S. Borrower and the Banks that the circumstances
causing such suspension no longer exist (and such Affected Bank shall give
notice promptly to the U.S. Administrative Agent and the U.S. Borrower upon
such circumstance ceasing to exist), and (ii) each Eurodollar Rate Advance of
such Affected Bank will automatically, upon such notice, Convert into a Base
Rate Advance on the last day of the then current Interest Period for such
Eurodollar Rate Advance or earlier upon such notice if the law so requires.  In
the event any Affected Bank shall notify the U.S. Administrative Agent of the
occurrence of any circumstance contemplated under this Section 2.14(a), all
payments of principal that would otherwise have been applied to repay the
Eurodollar Rate Advances that would have been made by such Affected Bank or the
Converted Eurodollar Rate Advances shall instead be applied to repay the Base
Rate Advances made by such Affected Bank in lieu of such Eurodollar Rate
Advances or resulting from the Conversion of such Eurodollar Rate Advances and
shall be made at the time that payments on the Eurodollar Rate Advances of the
Banks that are not Affected Banks are made.

              (b)     Notwithstanding any other provision of this Agreement, if
any Bank ("Canadian Affected Bank") shall notify the Canadian Administrative
Agent that any law or regulation makes it unlawful, or any central bank or
other governmental authority asserts that it is unlawful, for such Canadian
Affected Bank or its Canadian Bankers' Acceptance Lending Office to perform its
obligations hereunder to complete and accept Drafts, to purchase Bankers'
Acceptance or BA Equivalent Notes or to continue to fund or maintain BA
Obligations hereunder, (i) the obligation of such Canadian Affected Bank to
complete and accept Drafts and/or to purchase Bankers' Acceptance or BA
Equivalent Notes, or Convert Canadian Prime Rate Advances into BA Obligations,
shall be suspended (and any request by the Canadian Borrower for a Drawing
shall be





                                      -62-
<PAGE>   68
deemed a request for a Canadian Prime Rate Advance from such Canadian Affected
Bank to be made on the same date as the BA Obligations of the Banks that are
not Canadian Affected Banks and such Canadian Prime Rate Advance shall be
considered as part of such Drawing) until such Canadian Affected Bank shall
notify the Canadian Borrower and the Banks that the circumstances causing such
suspension no longer exist (and such Canadian Affected Bank shall give notice
promptly to the Canadian Administrative Agent and the Canadian Borrower upon
such circumstance ceasing to exist), (ii) an amount equal to the aggregate Face
Amount of all BA Obligations outstanding at such time, shall, upon such demand
(which shall only be made if reasonably deemed necessary by any Canadian Bank
to comply with applicable law), be deposited by the Canadian Borrower into the
Canadian Cash Collateral Account until the Maturity Date of each such BA
Obligation, and (iii) upon the Maturity Date of any BA Obligation in respect of
which any such deposit has been made, the U.S. Administrative Agent shall be,
and hereby is, authorized (without notice to or any further action by any
Borrower) to apply, or to direct the Canadian Administrative Agent to apply,
such amount (or the applicable portion thereof) to the reimbursement of such BA
Obligation.  In the event any Canadian Affected Bank shall notify the Canadian
Administrative Agent of the occurrence of any circumstance contemplated under
this Section 2.14(b), all payments of principal that would otherwise have been
applied to repay the BA Obligations that would have been made by such Canadian
Affected Bank shall instead be applied to repay the Canadian Prime Rate
Advances made by such Canadian Affected Bank in lieu of such BA Obligations and
shall be made at the time that payments on the BA Obligations of the Canadian
Banks that are not Canadian Affected Banks are made.

     Section 2.15.    Conversion of U.S. Advances; Interest Periods.  The U.S.
Borrower may on any Business Day, upon notice given to the U.S. Administrative
Agent not later than 11:00 A.M. (New York City time) on the third Business Day
prior to the date of the proposed Conversion (or in the case of notice to
Convert Eurodollar Advances or CD Rate Advances to Base Rate Advances not later
than 10:00 a.m. (New York City time) on the last day of the Interest Period for
such Eurodollar Rate Advance or such CD Rate Advance) and subject to the
provisions of Sections 2.01(d), 2.08 and 2.14, Convert all Advances of one U.S.
Type comprising the same Borrowing into Advances of another U.S. Type;
provided, however, that (i) if any Conversion of any Eurodollar Rate Advances
or CD Rate Advances into another U.S. Type of Advances is made on any day other
than the last day of an Interest Period for such Eurodollar Rate Advances or CD
Rate Advances, as the case may be, the U.S. Borrower shall be obligated to
reimburse the Banks in respect thereof pursuant to Section 8.04(b), and (ii)
Advances comprising a Borrowing may not be Converted into Eurodollar Rate
Advances or CD Rate Advances if the outstanding principal amount of such
Borrowing is less than





                                      -63-
<PAGE>   69
U.S. $10,000,000 or if any Event of Default under Section 6.01(a) or Section
6.01(e) shall have occurred and be continuing on the date the related notice of
Conversion would otherwise be given pursuant to this Section 2.15.  Each such
notice of a Conversion shall, within the restrictions specified above, specify
(i) the date of such Conversion, (ii) the Advances to be Converted, and (iii)
if such Conversion is into Eurodollar Rate Advances or CD Rate Advances, the
duration of the initial Interest Period for each such Advance.  Each notice of
Conversion shall be irrevocable and binding on the U.S. Borrower.  If any Event
of Default under Section 6.01(a) or Section 6.01(e) shall have occurred and be
continuing on the third Business Day prior to the last day of any Interest
Period for any Eurodollar Rate Advances or CD Rate Advances, the U.S. Borrower
agrees to Convert all such Advances into Base Rate Advances on the last day of
such Interest Period.  The U.S. Borrower may on any U.S. Business Day, upon
notice given to the U.S. Administrative Agent not later than 11:00 a.m. (New
York City time) on the third U.S. Business Day prior to the last day of any
Interest Period designate a new Interest Period to commence on the last day of
the existing Interest Period, in accordance with the provisions of the
definition herein of "Interest Period."

     Section 2.16.    Designation of Commitments.  On or prior to the date
hereof, the Borrowers shall execute and deliver to the U.S. Administrative
Agent a properly completed notice in the form of Exhibit J (a "Designation
Notice"), which Designation Notice delivered on or prior to the date hereof,
shall be effective upon the date hereof.  After the date hereof, the Borrowers
may deliver to the U.S. Administrative Agent a Designation Notice not more
frequently than eight times in any calendar year, each such Designation Notice
complying with the provisions of this Section 2.16 to be effective at 10:00
a.m. (New York City time) either (i) five U.S. Business Days (and at least
three Canadian Business Days) after receipt by the U.S. Administrative Agent or
(ii) if any notice has been given by the U.S. Administrative Agent pursuant to
Section 2.05(c) or if the Borrowers otherwise wish to make a designation
because the conditions referred to in the first sentence of Section 2.05(c)
then exist, on the Canadian Business Day (including the same day if the
appropriate Designation Notice is received by the U.S. Administrative Agent
before 10:00 a.m. (New York City time) on such day) specified by the Borrowers
in such Designation Notice received by the U.S. Administrative Agent before
10:00 a.m. (New York City time) on such Canadian Business Day, but such
specified Canadian Business Day may not be more than three Canadian Business
Days (but may be the same Canadian Business Day or otherwise less than three
Canadian Business Days if the appropriate Designation Notice is received by the
U.S. Administrative Agent before 10:00 a.m. (New York City time) on the
specified day as contemplated above) following such notice pursuant to Section
2.05(c).  Each Designation Notice shall be executed by each Borrower and shall
set forth therein the percentage of the Revolving Credit Facility





                                      -64-
<PAGE>   70
which will be available to the U.S. Borrower ("U.S. Percentage") and the
percentage of the Revolving Credit Facility which will be available to the
Canadian Borrower ("Canadian Percentage"), in each case until the effectiveness
of a replacement Designation Notice; provided that (i) the sum of such
percentages for the Borrowers must equal 100%, (ii) the product of the U.S.
Percentage multiplied by the Revolving Credit Facility shall be an integral
multiple of U.S. $1,000,000, (iii) the product of the Canadian Percentage
multiplied by the Revolving Credit Facility shall be an integral multiple of
U.S. $1,000,000, (iv) the percentage of the Revolving Credit Facility
designated with respect to any Borrower may not be less than the percentage of
the Revolving Credit Facility outstanding to (including, in the case of the
Canadian Borrower, the outstanding BA Obligations), or subject to then pending
Notices of Borrowing and Notices of Drawing of, such Borrower on the date such
notice is received by the U.S. Administrative Agent (unless such notice
specifies how such Borrower will be in compliance with the foregoing on the
date of effectiveness of such notice) and on the date of effectiveness of such
notice (in the case of Canadian Advances and BA Obligations, determined on the
basis of the U.S. Dollar Equivalent thereof), and (v) upon the effectiveness of
each such Designation Notice, such Designation Notice shall be binding on the
Borrowers until the effectiveness of a replacement Designation Notice.  No
Designation Notice may be delivered hereunder so long as any Event of Default
has occurred and is continuing.  Any contrary provision of this Agreement or
any other Loan Document notwithstanding, during the effectiveness of each such
Designation Notice, no Borrower may request, and no Bank shall have any
obligation to make Advances to, or other Accommodations for, such Borrower at
any time which would cause the aggregate principal amount and Face Amount of
Advances and other Accommodations outstanding to such Borrower to exceed the
amount equal to the product of the Applicable Designated Commitment Percentage
set forth for such Borrower in such Designation Notice multiplied by the
Revolving Credit Facility at such time.

     Section 2.17.    Replacement of Bank.  In the event that any Bank makes a
demand for payment under Section 2.11, requires any Taxes be withheld or
deducted under Section 2.12(a), makes demand for any indemnity under Section
2.12(c) or notifies either Administrative Agent of any circumstance pursuant to
Section 2.14 or 2.08(d)(B), the Borrowers may within 180 days of such demand,
if no Event of Default or Default then exists and no BA Obligations are then
outstanding (or if BA Obligations are outstanding, arrangements reasonably
satisfactory in all respects to such Bank are made to insure that such Bank
will be paid such BA Obligations in full on their Maturity Date, and the
Borrowers shall remain liable therefor), replace such Bank with an Eligible
Assignee in accordance with Section 8.08(a), (b) and (d) (including execution
of an appropriate Assignment and Acceptance) provided that (i) the Notes
payable to such Bank and all





                                      -65-
<PAGE>   71
other obligations owed to such Bank hereunder shall be purchased or paid in
full by such Assignee, without representation or recourse (except as provided
in such Assignment and Acceptance), at par plus accrued interest at or prior to
such replacement, (ii) such Eligible Assignee shall, from and after such
replacement, be deemed for all purposes to be a "Bank" hereunder, and shall
have all of the rights, duties and obligations hereunder of the Bank being
replaced, and (iii) such other actions shall be taken by the Borrowers, such
Bank and such Eligible Assignee as may be appropriate to effect the replacement
of such Bank with such Eligible Assignee on terms such that such Eligible
Assignee has from and after such replacement all of the rights, duties and
obligations hereunder as such Bank (including, without limitation, execution
and delivery of a Note to such Eligible Assignee, redelivery to the Borrower in
due course of the Note payable to such Bank and specification of the
information contemplated by Schedule II as to such Eligible Assignee).  No Bank
shall have any obligation to be such an Eligible Assignee or otherwise have any
obligation to replace any other Bank.

     Section 2.18.    Lending Office.  Any Bank that makes demand for payment
of additional amounts under Section 2.11, requires any Taxes be withheld or
deducted under Section 2.12(a), makes demand for any indemnity under Section
2.12(c) or notifies the U.S. Administrative Agent of any circumstance pursuant
to Section 2.14 or Section 2.08(d)(B), shall use reasonable efforts (consistent
with legal and regulatory restrictions) to designate a different Applicable
Lending Office if the making of such designation would avoid the need for, or
reduce the amount of, such additional amounts, withholding, deduction or
indemnity or avoid thereafter the circumstances that gave rise to such
notification; provided that no such designation need be made if such Bank
reasonably believes that it may suffer an economic, legal or regulatory
disadvantage or that such designation would be detrimental or otherwise
disadvantageous in any respect to such Bank.

     Section 2.19.    Renewal and Conversion of BA Obligations.  (a) The
Canadian Borrower may on any Canadian Business Day, upon notice given to the
U.S. Administrative Agent not later than 12:00 noon (New York City time) on the
third Canadian Business Day prior to the date of the proposed renewal and
subject to the provisions of Sections 2.08 and 2.14, renew all or any portion
of the BA Obligations comprising part of the same Drawing; provided that:

                      (i)      any renewal of BA Obligations shall be made only
on the then existing Maturity Date of such BA Obligations;

                      (ii)     each renewal of BA Obligations comprising part
of the





                                      -66-
<PAGE>   72
same Drawing shall be made ratably among the Banks holding such BA Obligations
in accordance with the respective amount of such BA Obligations so held
(counting Canadian Prime Rate Advances made under Section 2.03 or Section 2.19
in lieu thereof); and

                      (iii)    no renewal of any BA Obligation may be made at
any time that an Event of Default under Section 6.01(a) or Section 6.01(e) has
occurred and is continuing.

Each such notice of renewal shall, within the restrictions set forth above,
specify (A) the date of such renewal (which shall be the then existing Maturity
Date of such BA Obligations and shall be a Canadian Business Day), (B) the BA
Obligations to be renewed, (C) if less than all of the BA Obligations
comprising part of any Drawing are to be renewed, the aggregate Face Amount for
such renewal and (D) the term to maturity of the renewed BA Obligations (which
shall comply with the definition of "Maturity Date" in Section 1.01).  Each
Draft and BA Equivalent Note in connection with any renewal under this Section
2.19 (A) shall be in an amount of C$100,000 or an integral multiple of
C$100,000 in excess thereof, and (B) shall be dated the date of the proposed
renewal.  In the event that the Face Amount of any renewal requested by the
Canadian Borrower pursuant to this Section 2.19 is an amount which, if divided
ratably among the Canadian Banks would not result in each Canadian Bank
accepting a Draft or purchasing a BA Equivalent Note which has an undiscounted
face amount equal to C$100,000 or an integral multiple of C$100,000 in excess
thereof, then notwithstanding any provision in this Agreement to the contrary,
the Canadian Administrative Agent is authorized by the Canadian Borrower and
the Canadian Banks to allocate among the Canadian Banks, the Drafts to be
accepted and purchased and BA Equivalent Notes to be purchased in such manner
and amounts as the Canadian Administrative Agent may, in its sole discretion,
acting reasonably, consider necessary, rounding up or down, so as to ensure
that no Canadian Bank is required to accept a Draft for a fraction of $100,000
and, in such event, the Canadian Banks' ratable share with respect to such
Drafts and BA Equivalent Notes shall be adjusted accordingly; provided that no
Canadian Bank shall be required to purchase any Bankers' Acceptance or BA
Equivalent Note to the extent that the Face Amount thereof exceeds its then
Unused Commitment and such Canadian Bank shall fund any portion of its
allocated share in excess of its Bankers' Acceptance or BA Equivalent Note in
the form of a Canadian Prime Rate Advance, which shall for all purposes be
deemed to be a Canadian Borrower Advance made pursuant to Section 2.01(b).
Each notice of renewal under this Section 2.19 shall be irrevocable and binding
on the Canadian Borrower.  Upon any renewal of BA Obligations comprising part
of any Drawing in accordance with this Section 2.19(a), the Banks holding the





                                      -67-
<PAGE>   73
BA Obligations to be renewed shall exchange such maturing BA Obligations for
new BA Obligations containing the terms set forth in the applicable notice of
renewal, and the Drawing Purchase Price payable for each such renewal shall be
applied, together with other necessary funds of the Canadian Borrower, to
reimburse the BA Obligations otherwise maturing on such date in accordance with
Section 2.05(b).  The Canadian Borrower hereby irrevocably authorizes and
directs each Canadian Bank to apply the proceeds of each renewed BA Obligation
owing to it to the payment, in accordance with this Section 2.19(a), of the BA
Obligations owing to such Bank and maturing on such date, and the Canadian
Borrower will pay any remaining balance owing thereon.

              (b)     The Canadian Borrower may on any Canadian Business Day,
upon notice given to the U.S. Administrative Agent not later than 12:00 noon
(New York City time) on the third Canadian Business Day prior to the date of
the proposed Conversion and subject to the provisions of Sections 2.08 and
2.14, (i) Convert all or any portion of Canadian Prime Rate Advances comprising
the same Borrowing or Borrowings into a Drawing comprised of BA Obligations, or
(ii) Convert all or any portion of the BA Obligations comprising part of the
same Drawing to a Canadian Borrowing comprised of Canadian Prime Rate Advances;
provided, that:

                      (i)      any Conversion of BA Obligations shall be made
only on the then existing Maturity Date for such BA Obligations;

                      (ii)     each Conversion of BA Obligations comprising
part of the same Drawing shall be made ratably among the Banks holding such BA
Obligations in accordance with the respective amounts of such BA Obligations so
held;

                      (iii)    no Conversion may be made if the amount of the
Advance (determined on the basis of the U.S. Dollar Equivalent of such Advance)
to be made by any Canadian Bank in connection with such Conversion would exceed
such Bank's Unused Commitment in effect at the time of such Conversion;

                      (iv)     each Conversion into a Canadian Borrowing shall
be in an aggregate amount of C$1,000,000 or an integral multiple of C$100,000
in excess thereof;

                      (v)      each Conversion of Canadian Prime Rate Advances
into a Drawing shall be in an aggregate Face Amount of C$10,000,000 or an
integral multiple of C$100,000 in excess thereof and shall otherwise comply
with the requirements of, and be in accordance with, Sections 2.01(c), 2.01(d)
and 2.03; and

                      (vi)     no Conversion of Canadian Prime Rate Advances
into a





                                      -68-
<PAGE>   74
Drawing may be made at any time that an Event of Default under Section 6.01(a)
or Section 6.01(e) has occurred and is continuing.

Each such notice of Conversion shall, within the restrictions set forth above,
specify (A) the date of such Conversion (which shall be, in the case of any
Conversion of BA Obligations, the then existing Maturity Date of such BA
Obligations and shall be a Canadian Business Day), (B) the BA Obligations or
Canadian Prime Rate Advances, as the case may be, to be Converted, (C) if less
than all of the BA Obligations comprising part of any Drawing are to be
Converted into Canadian Prime Rate Advances, the aggregate Face Amount of such
Conversion, and (D) in the case of Conversion into BA Obligations, the term to
maturity of such BA Obligations (which shall comply with the definition of
"Maturity Date" in Section 1.01).  Each Draft and BA Equivalent Note in
connection with any such Conversion into BA Obligations under this Section 2.19
(A) shall be in an amount of C$100,000 or an integral multiple of C$100,000 in
excess thereof, and (B) shall be dated the date of the proposed Conversion.  In
the event that the Face Amount of any such Conversion requested by the Canadian
Borrower pursuant to this Section 2.19 is an amount which, if divided ratably
among the Canadian Banks would not result in each Canadian Bank accepting a
Draft or purchasing a BA Equivalent Note which has an undiscounted face amount
equal to C$100,000 or an integral multiple of C$100,000 in excess thereof, then
notwithstanding any provision in this Agreement to the contrary, the Canadian
Administrative Agent is authorized by the Canadian Borrower and the Canadian
Banks to allocate among the Canadian Banks, the Drafts to be accepted and
purchased and BA Equivalent Notes to be purchased in such manner and amounts as
the Canadian Administrative Agent may, in its sole discretion, acting
reasonably, consider necessary, rounding up or down, so as to ensure that no
Canadian Bank is required to accept a Draft for a fraction of $100,000 and, in
such event, the Canadian Banks' ratable share with respect to such Drafts and
BA Equivalent Notes shall be adjusted accordingly; provided that no Canadian
Bank shall be required to purchase any Bankers' Acceptance or BA Equivalent
Note to the extent that the Face Amount thereof exceeds its then Unused
Commitment and such Canadian Bank shall fund any portion if its allocated share
in excess of its Bankers' Acceptance or BA Equivalent Note in the form of a
Canadian Prime Rate Advance, which shall for all purposes be deemed to be a
Canadian Borrower Advance made pursuant to Section 2.01(b).  Each notice of
Conversion under this Section 2.19 shall be irrevocable and binding on the
Canadian Borrower.  Upon any Conversion of BA Obligations comprising part of
the same Drawing in accordance with this Section 2.19(b), the obligation of the
Canadian Borrower to repay the Banks under Section 2.05 in respect of the BA
Obligations otherwise maturing on such date shall, to the extent of such
Conversion, be Converted to an obligation to repay on the Termination Date the
Canadian Banks making the Canadian





                                      -69-
<PAGE>   75
Borrower Advances made in respect of such maturing BA Obligations on such date
ratably in accordance with the amount of the Canadian Advances held by such
Bank at the time of repayment.  The Canadian Borrower hereby irrevocably
authorizes and directs each Canadian Bank to apply the net proceeds of each
Canadian Prime Rate Advance made by such Canadian Bank pursuant to this Section
2.19(b) to the payment of the BA Obligations owing to such Bank and maturing on
such date, and the Canadian Borrower will pay any remaining balance on such
date.

              (c)     If any Event of Default under Section 6.01(a) or Section
6.01(e) shall have occurred and be continuing or if the Canadian Borrower shall
fail (i) to deliver a properly completed notice of renewal under Section
2.19(a) or a properly completed notice of Conversion under Section 2.19(b)
indicating its intention to renew or to Convert any maturing BA Obligations or
(ii) to pay the Canadian Banks for any BA Obligations comprising part of the
same Drawing pursuant to Section 2.05, the Canadian Administrative Agent will
forthwith so notify the U.S. Administrative Agent, the Canadian Borrower and
the Canadian Banks, and each of such BA Obligations will automatically, on the
then existing Maturity Date of such BA Obligations, Convert into a Canadian
Prime Rate Advance.

     Section 2.20.    Canadian Borrower.  Notwithstanding anything to the
contrary contained herein, nothing in this Agreement shall require the Canadian
Borrower to pay any amounts that are obligations of the U.S. Borrower (other
than those that are obligations of the U.S. Borrower by virtue of the Guaranty)
in respect of (i) any U.S. Advance or the U.S. Commitments, including (A) any
principal of, or interest on, any U.S. Advance; (B) any increased costs,
breakage costs or taxes payable in respect of any U.S. Advance pursuant to this
Agreement; (C) any other fees, costs or expenses relating to a U.S. Advance;
(D) any enforcement costs relating to a U.S. Advance; (ii) any fees owed to the
U.S. Administrative Agent or a U.S. Bank, including any commitment fee in
respect of the U.S. Commitments and any other Agent's fees or other fees
relating to the U.S. Commitments or the U.S. Advances; (iii) any reimbursement,
indemnification, contribution or other similar payment payable to any U.S. Bank
or the U.S. Administrative Agent; or (iv) any other amounts payable to a U.S.
Bank or the U.S. Administrative Agent or in respect of, or relating to, the
U.S. Commitments or any U.S. Advance.  Notwithstanding the foregoing, all
amounts referred to in this Section 2.20 shall be and remain the obligations of
the U.S. Borrower.

properties or reasonably foreseeable prospects of the U.S. Borrower and the
Consolidated Subsidiaries, taken as a whole.

     (g)      There is no pending or, to the knowledge of either Borrower,
threatened action, suit, litigation, investigation or proceeding (including any
Environmental Action, but excluding the Disclosed Litigation) affecting either
Borrower, any Subsidiary of either Borrower or any of its or their respective
rights or properties by or before any court, arbitrator or governmental
department, commission, board, bureau, agency or instrumentality, domestic or

<PAGE>   83
Adverse Effect or that in any manner draws into question or purports to affect

reorganization or to be terminated, within the meaning of Title IV of ERISA,

minimum statutory requirements, (v) to the knowledge of the U.S. Borrower and
the ERISA Affiliates, no termination of, or withdrawal from, any Plan has
occurred or is contemplated, and (vi) neither the U.S. Borrower nor any of the
Consolidated Subsidiaries has any liability with respect to "expected post
retirement benefit obligations" within the meaning of Statement of Financial
Accounting Standards No. 106 in addition to the amount disclosed in the U.S.
Borrower's report on Form 10-K for the year ended December 31, 1995, except
where the failure to comply with the foregoing would not reasonably be expected
to result in an aggregate liability in excess of U.S. $10,000,000.  All
contributions or premiums required to be paid by the Canadian Borrower have
been paid in a timely fashion in accordance with the terms of all registered
pension plans sponsored or contributed to by the Canadian Borrower on behalf of
the employees of its Canadian operations except where the failure to do so
would not reasonably be expected to result in a liability of the Canadian
Borrower in excess of U.S. $10,000,000.  To the knowledge of the Canadian
Borrower, no event has occurred and no condition or circumstance exists that
would reasonably be expected to result in any of its pension plans being
ordered or required to be terminated or wound-up in whole or in part, as a
result of which termination or winding up, the Canadian Borrower could
reasonably be expected to incur liability in excess of U.S. $10,000,000.

     (i)      Except where the failure to do so would not reasonably be
expected to have a Material Adverse Effect, the Borrowers and each of their
Subsidiaries have filed all Federal, both U.S. and Canadian, and state and
provincial income tax returns which, to the knowledge of either Borrower, are
required to be filed, and each has paid all taxes as shown on said returns and
on all assessments received by it to the extent that such taxes and assessments
have become due (other than any taxes or assessments the amount, applicability
or validity of which are currently being contested in good faith by appropriate
proceedings and with respect to which the Borrowers and their Subsidiaries have
established adequate reserves in accordance with GAAP) with the appropriate
taxing





                                      -78-

authority.  Federal, both U.S. and Canadian, and state and provincial income
tax returns of the Borrowers and their respective Subsidiaries have been
examined and reported on by the taxing authorities or closed by applicable
statutes and satisfied for all fiscal years prior to and including 1990.

     (j)      Neither Borrower is an "investment company" or a company

and all applicable law, rules, regulations and orders pertaining thereto and
not have any liability with respect to "expected post retirement obligations"
within the meaning of Statement of Financial Accounting Standards No. 106 in
addition to the amount disclosed in the U.S. Borrower's report on Form 10-K for
the year ended December 31, 1995, except where the failure to comply with this

liability in excess of $10,000,000.

     (n)      Collateral Account.  In the event that the Banks shall have
declared the Notes to be due and payable pursuant to Section 6.01 or if a
deposit in the Canadian Cash Collateral Account is required pursuant to Section
2.09 or 2.14 or made pursuant to Section 2.04(d), take such actions, to the
extent not prohibited by applicable law, as may be requested by the Canadian
Administrative Agent to establish and maintain, and create and maintain a
perfected first priority security interest in favor of the Canadian
Administrative Agent for the equal and ratable benefit of the Canadian Banks
securing repayment of the BA Obligations in, one or more collateral accounts
(collectively, the "Canadian Cash Collateral Account"), over which the Canadian
Administrative Agent shall have sole dominion and control, for purposes of
making and holding the deposits required or permitted hereunder to be made to
the Canadian Cash Collateral Account and any Canadian treasury obligations
acquired in accordance with the next sentence hereof.  To the extent that a
perfected first priority security interest cannot be taken and maintained in
the Canadian Cash Collateral Account under applicable Canadian law or to the
extent that any such deposits under the sole dominion and control of the
Canadian Administrative Agent are not retained in the Canadian Cash Collateral
Account, the Canadian Administrative Agent may (and if instructed by the
Required Banks, shall) invest such deposits in Canadian treasury obligations,
and such Canadian treasury

     property that did not secure such Debt immediately prior to such renewal,
     extension or refinancing.

either Borrower to make, any change in the nature of their respective

the Borrower and any Subsidiary of either Borrower may enter into any
arrangement or other transaction with any such Affiliate if the arrangement or
other transaction is substantially at least as advantageous to such Borrower or
such Subsidiary, as the case may be, as would be obtained in a comparable arm's

     (i)      Restricted Payments.  Directly or indirectly, declare (in the
case of the U.S. Borrower), pay or make, or permit any of its Subsidiaries,

Default would result from such Restricted Payment; provided that this Section
5.02(i) will not prohibit the U.S. Borrower from paying any dividend or other

5.02(l) by an investor using any asset (other than cash) in any Person, and in
the event that (X) such Investment is not otherwise excepted from this Section

reserves, to cease to be a Wholly-Owned Subsidiary of the U.S. Borrower that is
not a Dividend Restricted Subsidiary.

     Section 5.03.    Financial Covenants.  So long as any Advance or any other
amount payable by either Borrower hereunder or under any Note shall remain
unpaid or any BA Obligation shall be outstanding or any Bank shall have any
Commitment hereunder, the U.S. Borrower will:

     (a)      Debt to Capitalization.  Maintain at all times a ratio of Total
Consolidated Debt to Total Capitalization equal to or less than (i) 42.5% minus
(ii) the Ratio Reduction Percentage, if any, at such time.

     (b)      Minimum Consolidated Tangible Net Worth.  Maintain at all times a
Consolidated Tangible Net Worth equal to or greater than the sum of (i) U.S.
$430,000,000, plus (ii) 50% of cumulative Consolidated net income of the U.S.
Borrower, if positive, after September 30, 1996, plus (iii) 50% of aggregate
Equity Proceeds received by the U.S. Borrower after September 30, 1996 plus
(iv) 50% of the principal amount of any Debt of the U.S. Borrower or any
Consolidated Subsidiary converted into capital stock of the U.S. Borrower after
September 30, 1996.

     (c)      Fixed Charge Coverage Ratio.  Cause (i) for each period of four
consecutive fiscal quarters of the U.S. Borrower ending on or before September
30, 1998, the ratio of EBITDA to Fixed Charges to be equal to or greater than
2.75 to 1, and (ii) for each period of four consecutive fiscal quarters of the
U.S. Borrower ending after September 30, 1998, the ratio of EBITDA to Fixed
Charges to be equal to or greater than 3.5 to 1.

     Section 5.04.    Non-Wholly Owned Entities and Joint Ventures.  In respect
of all covenants and agreements of the Borrowers to cause or permit or not
permit any activities by any Subsidiaries of any Borrower or other entities or
joint ventures that are not wholly-owned (directly or indirectly) by any
Borrower, each of the Borrowers expressly





                                      -96-
<PAGE>   102
advises the Administrative Agents and the Banks that:  (a) each of the
Borrowers may be subject to fiduciary or other duties as shareholders, partners
or otherwise or to legal obligations under or in connection with relevant joint
venture or other organizational agreements or documents (such duties and
obligations herein referred to as "Duties"); and (b) each of the Borrowers
fully intends to comply with all of its respective Duties.  Each of the
Borrowers expressly agrees that all provisions of this Agreement and the other
Loan Documents will be construed and enforced without reference to the
foregoing sentence of this Section 5.04.  Without limitation to the foregoing,
each of the Borrowers understands and agrees that, in the event that a Duty of
a Borrower with respect to a non-wholly-owned entity were to conflict with such
Borrower's compliance of a covenant or agreement in this Agreement or any other
Loan Document, such Borrower's failure to comply with such covenant or
agreement would not be excused and would have the same consequences as if such
Borrower had failed to comply with such covenant or agreement with respect to a
wholly-owned entity.

by Section 2.05(c) or any interest on any Advance or any fees hereunder or
other amount payable hereunder, in each case covered by this clause (2) within
five days of when the same becomes due and payable, whether at the due date
thereof or by acceleration thereof or otherwise; or

     (b)  Any representation, warranty or certification made by either Borrower
herein or by either Borrower (or any officer on behalf of either Borrower)
pursuant to or in connection with this Agreement or the Guaranty or in any
certificate or notice furnished to any Bank pursuant to or in connection with
this Agreement or the Guaranty, or any representation or warranty deemed to

and such failure shall remain unremedied for 10 days after either Borrower has
knowledge of such failure or notice thereof shall have been given to the U.S.
Borrower by either Administrative Agent or by any Bank, or (iii) any other

any covenant or agreement covered by clause (i) or clause (ii) of this Section
6.01(c) or by Section 6.01(a)) and such failure shall remain unremedied for 30
days after either Borrower has knowledge of such failure or notice thereof
shall have been given to the U.S. Borrower by either Administrative Agent or by
any Bank; or

     (d)      Either Borrower or any Subsidiary of either Borrower shall

acceleration or otherwise, of any Debt (whether principal, interest, premium or
otherwise, but excluding any Project Financing Debt and any Debt covered by
Section 6.01(a)) of, or directly or indirectly guaranteed by, either Borrower
or any Subsidiary of either Borrower, as the case may be, having a principal

either Borrower or any Subsidiary of either Borrower shall default in the
performance or observance of, shall breach or shall fail to perform or observe,
any obligation or condition with respect to any such Debt if the effect of such

to accelerate the maturity of any such Debt; or

     (e)      Either Borrower or any Subsidiary of either Borrower shall be

"generally not pay its debts as such debts become due" within the meaning of a

to pay its debts generally, or shall make a general assignment for the benefit
of creditors; or any proceeding shall be instituted by or against either
Borrower or any Subsidiary of either Borrower seeking to adjudicate it a
bankrupt or insolvent, or seeking liquidation, provisional liquidation, winding
up, reorganization, arrangement, adjustment, protection, relief or composition
of it or its debts under any law relating to bankruptcy, insolvency or
reorganization or relief of

debtors, or seeking the entry of an order for relief or the appointment of a
receiver, trustee, custodian or other similar official for it or for any
substantial part of its property and, in the case of any such proceeding
instituted against it (but not instituted by it), either such proceeding shall
remain undismissed or unstayed for a period of 60 days, or any of the foregoing
actions sought in such proceeding (including the entry of an order for relief
against it or the appointment of a receiver, trustee, custodian or other

subsection (e); or

     (f)      Any judgment or order for the payment of money in excess of
$10,000,000 over the amount covered by insurance or any non-monetary judgment
or order (other than those non-monetary judgments and orders that would not
reasonably be expected to have a Material Adverse Effect) shall be rendered

enforcement proceedings shall have been commenced by any creditor upon such
judgment or order or (ii) there shall be any period of 30 consecutive days
during which such judgment or order shall remain unsatisfied (in the case of a
monetary judgment) and unstayed; or

     (g)      The U.S. Borrower or any of its ERISA Affiliates shall incur, or
shall be reasonably likely to incur, liability in excess of $10,000,000 in the
aggregate as a result of one or more of the following:  (i) the occurrence of
any ERISA Event; (ii) the partial or complete withdrawal of the U.S. Borrower
or any of its ERISA Affiliates from a Multiemployer Plan; or (iii) the
reorganization or termination of a Multiemployer Plan; or

     (h)      Any ERISA Event shall have occurred with respect to a Plan and
the sum (determined as of the date of occurrence of such ERISA Event) of the
Insufficiency of such Plan and the Insufficiency of any and all other Plans
with respect to which an ERISA Event shall have occurred and then exist (or the
liability of the U.S. Borrower and the ERISA Affiliates related to such ERISA
Event) exceeds $10,000,000; or

     (i)      The U.S. Borrower or any ERISA Affiliate shall have been notified

by the





                                      -99-
<PAGE>   105
sponsor of a Multiemployer Plan that such Multiemployer Plan is in
reorganization or is being terminated, within the meaning of Title IV of ERISA,
and as a result of such reorganization or termination the aggregate
contributions of the Borrowers and the ERISA Affiliates to all Multiemployer
Plans that are then in reorganization or being terminated have been or will be
increased over the amounts contributed to such Multiemployer Plans for the plan
years of such Multiemployer Plans immediately preceding the plan year in which
such reorganization or termination occurs by an amount exceeding $10,000,000
for all plan years; or

     (k)      The Canadian Borrower shall fail to pay in a timely fashion in
accordance with the terms of any registered pension plan sponsored or
contributed to by the Canadian Borrower on behalf of the employees of its
Canadian operations any contribution or premium required to be paid by the
Canadian Borrower to such pension plan, where all such failures in the
aggregate result in a liability of the Canadian Borrower in excess of U.S.
$10,000,000; or

     (l)      The occurrence of any event or existence of any condition or
circumstance that would reasonably be expected to result in any of the Canadian
Borrower's pension plans being ordered or required to be terminated or wound-
up in whole or in part, as a result of which termination or winding up, the
Canadian Borrower would reasonably be expected to incur liability in excess of
U.S. $10,000,000; or

     (m)      Any of the Loan Documents (other than the Canadian Notes, the
Drafts and the BA Equivalent Notes) shall for any reason cease to be the legal,
valid, binding and enforceable obligation of the U.S. Borrower or any of the
Loan Documents (other than the Guaranty and the U.S. Notes) shall cease to be
the legal, valid, binding and enforceable obligation of the Canadian Borrower
or either Borrower shall so state in writing;

then, and in any such event, the U.S. Administrative Agent (i) shall at the
request, or may with the consent, of the Required Banks, by notice to the
Borrowers, declare the obligation of each Bank to make Advances and of each
Canadian Bank to accept and/or purchase BA Obligations to be terminated,
whereupon the same (and all of the Commitments) shall forthwith terminate, and
(ii) shall at the request, or may with the consent, of the Required Banks, by
notice to the Borrowers, declare the Notes, all interest thereon and all other
amounts payable under this Agreement to be forthwith due and payable, whereupon
the Notes, all such interest and all such other amounts shall become and be
forthwith due and payable, without presentment, demand, protest, notice of
intent to accelerate, notice of acceleration or any other notice of any kind,
all of which are





                                     -100-
<PAGE>   106
hereby expressly waived by the Borrowers (other than the notices provided in
the immediately preceding clauses (i) and (ii) above); provided, however, that
in the event of any Event of Default described in Section 6.01(e), (A) the
obligation of each Bank to make Advances and of each Canadian Bank to accept
and/or purchase BA Obligations (and all of the Commitments) shall automatically
be terminated, and (B) the Notes, all interest thereon and all other amounts
payable under this Agreement shall automatically and immediately become and be
due and payable, without presentment, demand, protest, notice of intent to
accelerate, notice of acceleration, or any other notice of any kind, all of
which are hereby expressly waived by the Borrowers.

     Section 6.02     Actions in Respect of BA Obligations.  (a)  If any Event
of Default shall have occurred and be continuing and the Canadian Notes shall
have been declared to be, or shall have automatically become, due and payable
pursuant to Section 6.01 or, if any BA Obligation shall be outstanding on or
after the Termination Date, the U.S. Administrative Agent shall at the request,
or may with the consent, of the Required Banks, irrespective of whether it is
taking any of the actions described in Section 6.01 or otherwise, make demand
upon the Canadian Borrower to, and forthwith upon such demand such Borrower
will, pay to the Canadian Administrative Agent on behalf of the Canadian Banks,
in same day funds, at the Canadian Administrative Agent's office designated in
such demand, for deposit in the Canadian Cash Collateral Account, an amount
equal to the aggregate Face Amount of all BA Obligations then outstanding.

     (b)      If any Event of Default shall have occurred and be continuing and
the Canadian Notes shall have been declared to be, or shall have automatically
become, due and payable pursuant to Section 6.01, or if any BA Obligation shall
be outstanding on or after the Termination Date, and  either Administrative
Agent determines that any funds held in the Canadian Cash Collateral Account
are subject to any right or claim of any Person other than the Canadian Banks
to secure repayment of the BA Obligations or that the total amount of such
funds is less than the aggregate Face Amount of all outstanding BA Obligations,
the Canadian Borrower will, forthwith upon demand by the Canadian
Administrative Agent, pay to the Canadian Administrative Agent as additional
funds to be deposited and held in the Canadian Cash Collateral Account, an
amount equal to the excess of (A) the aggregate Face Amount of all outstanding
BA Obligations over (B) the total amount of funds, if any, then held in the
Canadian Cash Collateral Account that the Canadian Administrative Agent
reasonably determines to be free and clear of any such right or claim.

                                  ARTICLE VII
                           THE ADMINISTRATIVE AGENTS

     Section 7.01.    Authorization and Action.  Each Bank hereby appoints and
authorizes each Administrative Agent to take such action as such agent on its
behalf and to exercise such powers under the Loan Documents as are delegated to
such Administrative Agent by the terms hereof or of any other Loan Document,
together with such powers and discretion as are reasonably incidental thereto.
As to any matters not expressly provided for by this Agreement (including
enforcement or collection of the Guaranty or any of the Notes), no
Administrative Agent shall be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions
of the Required Banks and such instructions shall be binding upon all Banks and
all holders of Notes; provided, however, that no Administrative Agent shall be
required to take any action which exposes such Administrative Agent to personal
liability or which is contrary to any Loan Document or applicable law.  The
U.S. Administrative Agent agrees to give to each U.S. Bank prompt notice of
each notice received by it pertaining to a U.S. Borrowing or a payment thereon
and to each Bank prompt notice of each other notice received by it (unless
notice thereof is given by the Canadian Administrative Agent).  The Canadian
Administrative Agent agrees to give to each Canadian Bank prompt notice of each
notice received by it pertaining to a Canadian Borrowing, a Drawing or a
payment thereon and to each Bank prompt notice of each other notice received by
it (unless notice thereof is given by the U.S. Administrative Agent).

     Section 7.02.    Administrative Agents' Reliance, Etc.  Neither
Administrative Agent nor any director, officer, agent or employee of either
Administrative Agent shall be liable to any Bank for any action taken or
omitted to be taken by it or them under or in connection with any Loan
Document, except for its or their own gross negligence or willful misconduct.
Without limitation of the generality of the foregoing, each Administrative
Agent:  (i) may treat the payee of any Note as the holder thereof until such
Administrative Agent receives and accepts an Assignment and Acceptance entered
into by the Bank which is the payee of such Note, as assignor, and an Eligible
Assignee, as assignee, as provided in Section 8.08; (ii) may consult with legal
counsel, independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken in good faith
by it in accordance with the advice of such counsel, accountants or experts;
(iii) makes no warranty or representation to any Bank and shall not be
responsible to any Bank for any statements, warranties or representations
(whether written or oral) made in or in connection with any of the Loan
Documents or any other instrument or document; (iv) shall not have any duty to
any Bank to ascertain or to inquire as to the performance or observance of any
of the terms, covenants or





                                     -102-
<PAGE>   108
conditions of any of Loan Documents or any other instrument or document on the
part of either Borrower or any Subsidiary of either Borrower or to inspect the
property (including the books and records) of either Borrower or any Subsidiary
of either Borrower; (v) shall not be responsible to any Bank for the due
execution, legality, validity, enforceability, genuineness, sufficiency or
value of any of the Loan Documents or any other instrument or document; and
(vi) shall incur no liability to any Bank under or in respect of any of Loan
Documents or any other instrument or document by acting upon any notice
(including telephonic notice), consent, certificate or other instrument or
writing (which may be by telecopier, telegram or telex) believed by it to be
genuine and signed, given or sent by the proper party or parties.

     Section 7.03.    Citibank, Citibank Canada and Affiliates.  With respect
to its Commitment, the Advances owed to it and the Notes issued to it, each of
Citibank and Citibank Canada shall have the same rights and powers under the
Loan Documents as any other Bank and may exercise the same as though it were
not an Administrative Agent; and the term "Bank" or "Banks" shall, unless
otherwise expressly indicated, include Citibank and Citibank Canada in its
individual capacity.  Each of Citibank and Citibank Canada and their respective
affiliates may accept deposits from, lend money to, act as trustee under
indentures of, accept investment banking engagements from and generally engage
in any kind of business with, the Borrowers, any Affiliate of either Borrower
and any Person who may do business with or own securities of either Borrower or
any Affiliate of either Borrower, all as if Citibank or Citibank Canada, as the
case may be, were not an Administrative Agent and without any duty to account
therefor to the Banks.

     Section 7.04.    Bank Credit Decision.  Each Bank acknowledges that it
has, independently and without reliance upon either Administrative Agent or any
other Bank and based on the Financial Statements and such other documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement.  Each Bank also acknowledges that it
will, independently and without reliance upon either Administrative Agent or
any other Bank and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under the Loan Documents or any other instrument or document.

     SECTION 7.05.    INDEMNIFICATION.  THE BANKS AGREE TO INDEMNIFY EACH
ADMINISTRATIVE AGENT (TO THE EXTENT NOT REIMBURSED BY THE BORROWER), RATABLY
ACCORDING TO THE RESPECTIVE PRINCIPAL AMOUNTS OF THE NOTES THEN HELD BY EACH OF
THEM (OR IF NO ADVANCES ARE AT THE TIME OUTSTANDING OR IF ANY NOTES ARE HELD BY
PERSONS WHICH ARE NOT BANKS, RATABLY ACCORDING TO EITHER (A) THE RESPECTIVE
AMOUNTS OF THEIR





                                     -103-
<PAGE>   109
COMMITMENTS, OR (B) IF NO COMMITMENTS ARE AT THE TIME OUTSTANDING, THE
RESPECTIVE AMOUNTS OF THE COMMITMENTS IMMEDIATELY PRIOR TO THE TIME THE
COMMITMENTS CEASED TO BE OUTSTANDING), FROM AND AGAINST ANY AND ALL
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH
MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST SUCH ADMINISTRATIVE AGENT
IN ANY WAY RELATING TO OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY OTHER
INSTRUMENT OR DOCUMENT FURNISHED PURSUANT HERETO OR IN CONNECTION HEREWITH, OR
ANY ACTION TAKEN OR OMITTED BY SUCH ADMINISTRATIVE AGENT UNDER ANY OF THE LOAN
DOCUMENTS OR ANY OTHER INSTRUMENT OR DOCUMENT FURNISHED PURSUANT HERETO OR IN
CONNECTION HEREWITH; PROVIDED THAT NO BANK SHALL BE LIABLE FOR ANY PORTION OF
SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM SUCH ADMINISTRATIVE
AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.  Without limitation of the
foregoing, each Bank agrees to reimburse either Administrative Agent promptly
upon demand for such Bank's ratable share of any out-of-pocket expenses
(including counsel fees) incurred by such Administrative Agent in connection
with enforcement (whether through negotiations, legal proceedings or otherwise)
of, or legal advice in respect of rights or responsibilities under, any of the
Loan Documents or any other instrument or document furnished pursuant hereto or
in connection herewith to the extent that such Administrative Agent is not
reimbursed for such expenses by the Borrower.

     Section 7.06.    Successor Administrative Agents.  Subject to the
appointment of and acceptance by a successor Administrative Agent as provided
below, each Administrative Agent may resign at any time by giving written
notice thereof to the Banks and the Borrowers and may be removed at any time
with or without cause by the Required Banks.  Upon any such resignation or
removal, the Required Banks shall have the right to appoint any Bank, or with
the consent of the U.S. Borrower (which consent shall not be unreasonably
withheld), any Eligible Assignee as a successor Administrative Agent to assume
the duties of such resigning or removed Administrative Agent.  If no such
successor Administrative Agent shall have been so appointed by the Required
Banks (and, if not a Bank, approved by the Borrower), and shall have accepted
such appointment, within 30 days after the retiring Administrative Agent's
giving of notice of resignation or the Required Banks' removal of the retiring
Administrative Agent, then the retiring Administrative Agent may, on behalf of
the Banks, appoint any Bank, or with the consent of the U.S. Borrower (which
consent shall not be unreasonably withheld), any Eligible Assignee as a
successor Administrative Agent. Upon the acceptance of any appointment as an
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested
with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the





                                     -104-
<PAGE>   110
retiring Administrative Agent shall be discharged from its duties and
obligations under this Agreement and the other Loan Documents.  After any
retiring Administrative Agent's resignation or removal hereunder as an
Administrative Agent, the provisions of this Article VII shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was an
Administrative Agent under this Agreement.  If any Administrative Agent resigns
or is removed as an Administrative Agent and if any Affiliate thereof continues
to perform its duties as an Administrative Agent ("Continuing Administrative
Agent"), upon the written request of the U.S. Borrower, the Continuing
Administrative Agent shall resign and may be replaced in accordance with the
provisions of this Section 7.06.


                                  ARTICLE VIII
                                 MISCELLANEOUS

     Section 8.01.    Amendments, Etc.  No amendment or waiver of any provision
of this Agreement or any Note, nor consent to any departure by the Borrowers
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Required Banks, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided that no such amendment, waiver or consent shall, unless in
writing and signed by all the Banks, do any of the following: (a) waive any of
the conditions specified in Section 3.01 or clause (iii) of Section 3.02, (b)
increase the Commitment of any Bank or subject any Bank to any additional
obligations (provided that no amendment or waiver of, or consent to any
departure from, any representation or warranty, covenant or Event of Default,
any of which would not otherwise require the approval of all of the Banks,
shall be deemed to "subject any Bank to any additional obligations" for the
purposes of this clause (b) only), (c) reduce the principal of, or interest on,
the Notes or any fees or other amounts payable hereunder, (d) postpone any date
fixed for any payment of principal of, or interest on, the Notes or any fees or
BA Obligations or Drawing Fees payable hereunder, (e) change the percentage of
the Commitments or of the aggregate unpaid principal amount of the Notes and
aggregate Face Amount of BA Obligations which shall be required for the Banks
or any of them to take any action hereunder, (f) change the definition herein
of "Termination Date", or (g) amend this Section 8.01; and provided, further,
that no amendment, waiver or consent shall, unless in writing and signed by an
Administrative Agent in addition to the Banks required above to take such
action, affect the rights or duties of such Administrative Agent under this
Agreement or any of the Notes.

     Section 8.02.    Notices, Etc.  All notices and other communications
provided for hereunder shall be in writing (including telecopier communication)

     (b)      If any payment (or purchase pursuant to Section 2.17) of

Agent), pay to the U.S. Administrative Agent for the account of such Bank any
amounts required to compensate such Bank for any additional losses, costs or
expenses which it may reasonably incur as a result of such payment, purchase or
Conversion, including any loss (excluding loss of anticipated profits), cost or
expense actually incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by any Bank to fund or maintain such Advance.
A certificate as to the amount of such additional losses, costs or expenses,
submitted to the U.S. Borrower and the U.S. Administrative Agent by such Bank,
shall be conclusive and binding for all purposes, absent manifest error;
provided that the determination thereof is made on a reasonable basis.  Such
certificate shall be in reasonable detail but such Bank shall not be required
to disclose any confidential or proprietary information therein.  If any
payment of principal of, or Conversion of, any BA Obligation is made other than

error; provided that the determination thereof is made on a reasonable basis.
Such certificate shall be in reasonable detail but such Bank shall not be
required to disclose any confidential or proprietary information therein.

     (c)      EACH BORROWER AGREES TO INDEMNIFY AND HOLD HARMLESS EACH
INDEMNIFIED PARTY FROM AND AGAINST ANY AND ALL CLAIMS, DAMAGES, LOSSES,
LIABILITIES AND EXPENSES (INCLUDING REASONABLE FEES AND EXPENSES OF COUNSEL,
BUT EXCLUDING ALLOCATED OVERHEAD AND EXCLUDING, PRIOR TO THE OCCURRENCE OF AN
EVENT OF DEFAULT, LEGAL COSTS OF ANY OF THE BANKS OR ANY DIRECTOR, OFFICER,
EMPLOYEE, AFFILIATE, ADVISOR OR AGENT OF ANY OF THE BANKS) THAT MAY BE INCURRED
BY OR ASSERTED OR AWARDED AGAINST SUCH INDEMNIFIED PARTY, IN EACH CASE ARISING
OUT OF OR IN CONNECTION WITH OR BY REASON OF, OR IN CONNECTION WITH THE
PREPARATION FOR A DEFENSE OF, ANY INVESTIGATION, LITIGATION, OR PROCEEDING
ARISING OUT OF, RELATED TO OR IN CONNECTION WITH ANY OF THE COMMITMENTS OR ANY
LOAN DOCUMENT, WHETHER OR NOT SUCH INDEMNIFIED PARTY IS A PARTY THERETO, AND
WHETHER OR NOT ANY BORROWING OR DRAWING IS MADE HEREUNDER, AND INCLUDING ANY
SUCH CLAIM, DAMAGE, LOSS, LIABILITY OR EXPENSE RESULTING FROM THE NEGLIGENCE OF
SUCH INDEMNIFIED PARTY, EXCEPT TO THE EXTENT SUCH CLAIM, DAMAGE, LOSS,
LIABILITY OR EXPENSE IS FOUND IN A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF
COMPETENT JURISDICTION TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF SUCH INDEMNIFIED PARTY.

     (d)      Without prejudice to the survival of any other agreement of the
Borrowers hereunder, all obligations of the Borrowers under Section 2.11,
Section 2.12 and this Section 8.04 shall survive the termination of the
Commitments and this Agreement and the payment in full of all amounts hereunder
and under the Notes.

     Section 8.05.    Right of Set-Off.  Upon (i) the occurrence and during the
continuance of any Event of Default and (ii) the making by the Required Banks
of the request or the granting by the Required Banks of the consent specified
by Section 6.01 to authorize the U.S. Administrative Agent to declare the Notes
due and payable pursuant to the provisions of Section 6.01, each Bank is hereby
authorized at any time and from time





                                     -108-
<PAGE>   114
to time, to the fullest extent permitted by law, to set off and apply any and
all deposits (general or special, time or demand, provisional or final) at any
time held and other indebtedness at any time owing by such Bank (or by any
branch thereof) to or for the credit or the account of either Borrower against
any and all of the obligations of such Borrower now or hereafter existing under
this Agreement or any Note held by such Bank, whether or not such Bank shall
have made any demand under this Agreement, the Guaranty or any such Note and
although such obligations may be unmatured.  Each Bank agrees promptly to
notify the applicable Borrower after any such set-off and application made by
such Bank, provided that the failure to give such notice shall not affect the
validity of such set-off and application.  The rights of each Bank under this
Section are in addition to other rights and remedies (including other rights of
set-off) which such Bank may have.

     Section 8.06.    Limitation and Adjustment of Interest.   (a)
Notwithstanding anything to the contrary set forth herein, in any other Loan
Document or in any other document or instrument, no provision of any of the
Loan Documents or any other instrument or document furnished pursuant hereto or
in connection herewith is intended or shall be construed to require the payment
or permit the collection of interest in excess of the maximum non-usurious rate
permitted by applicable law.  Accordingly, if the transactions with any Bank
contemplated hereby would be usurious under applicable law, if any, then, in
that event, notwithstanding anything to the contrary in any Note payable to
such Bank, this Agreement, any other Loan Document or any other document or
instrument, it is agreed as follows:  (i) the aggregate of all consideration
which constitutes interest under applicable law that is contracted for, taken,
reserved, charged or received by such Bank under any Note payable to such Bank,
this Agreement or any other Loan Document or under any other document or
instrument shall under no circumstances exceed the maximum amount allowed by
such applicable law, and any excess shall be canceled automatically and, if
theretofore paid, shall, at the option of such Bank, be credited by such Bank
on the principal amount of the indebtedness owed to such Bank by the relevant
Borrower or refunded by such Bank to such Borrower, and (ii) in the event that
the maturity of any Note payable to such Bank is accelerated or in the event of
any required or permitted prepayment, then such consideration that constitutes
interest under law applicable to such Bank may never include more than the
maximum amount allowed by such applicable law and excess interest, if any, to
such Bank provided for in this Agreement or otherwise shall be canceled
automatically as of the date of such acceleration or prepayment and, if
theretofore paid, shall, at the option of such Bank, be credited by such Bank
on the principal amount of the indebtedness owed to such Bank by the relevant
Borrower or refunded by such Bank to such Borrower.  In determining whether or
not the interest contracted for, taken, reserved, charged or received by any





                                     -109-
<PAGE>   115
Bank exceeds the maximum non-usurious rate permitted by applicable law, such
determination shall be made, to the extent that doing so does not result in a
violation of applicable law, by amortizing, prorating, allocating and
spreading, in equal parts during the period of the full stated term of the
loans hereunder, all interest at any time contracted for, taken, charged,
received or reserved by such Bank in connection with such loans.

     (b)      In the event that at any time the interest rate applicable to any
Advance made by any Bank would exceed the maximum non-usurious rate allowed by
applicable law, the rate of interest to accrue on the Advances by such Bank
shall be limited to the maximum non-usurious rate allowed by applicable law,
but shall accrue, to the extent permitted by law, on the principal amount of
the Advances made by such Bank from time to time outstanding, if any, at the
maximum non-usurious rate allowed by applicable law until the total amount of
interest accrued on the Advances made by such Bank equals the amount of
interest which would have accrued if the interest rates applicable to the
Advances pursuant to Article II had at all times been in effect.  In the event
that upon the final payment of the Advances made by any Bank and termination of
the Commitment of such Bank, the total amount of interest paid to such Bank
hereunder and under the Notes is less than the total amount of interest which
would have accrued if the interest rates applicable to such Advances pursuant
to Article II had at all times been in effect, then the Borrower agrees to pay
to such Bank, to the extent permitted by law, an amount equal to the excess of
(a) the lesser of (i) the amount of interest which would have accrued on such
Advances if the maximum non-usurious rate allowed by applicable law had at all
times been in effect or (ii) the amount of interest which would have accrued on
such Advances if the interest rates applicable to such Advances pursuant to
Article II had at all times been in effect over (b) the amount of interest
otherwise accrued on such Advances in accordance with this Agreement.

     (c)      Notwithstanding any provision to the contrary contained in this
Agreement, in no event shall the aggregate "interest" (as defined in Section
347 of the Criminal Code (Canada), as the same may be amended, replaced or
re-enacted from time to time) payable under this Agreement by the Canadian
Borrower exceed the maximum amount of interest on the "credit advanced" (as
defined in that section) under this Agreement to the Canadian Borrower lawfully
permitted under that section and, if any payment, collection or demand pursuant
to this Agreement in respect of "interest" (as defined in that section) payable
by the Canadian Borrower is determined to be contrary to the provisions of that
section, such payment, collection or demand shall be deemed to have been made
by mutual mistake of the Canadian Borrower, the Canadian Administrative Agent
and the Canadian Banks and the amount of such payment or collection in excess
of the amount lawfully permitted shall be refunded to the Canadian





                                     -110-
<PAGE>   116
Borrower.  For purposes of this Agreement, the effective annual rate of
interest on all such "credit advanced" to the Canadian Borrower shall be
determined in accordance with generally accepted actuarial practices and
principles over the term the Revolving Credit Facility is outstanding on the
basis of annual compounding of the lawfully permitted rate of interest and, in
the event of any dispute, a certificate of Fellow of the Canadian Institute of
Actuaries appointed by the Canadian Administrative Agent will be conclusive for
the purposes of such determination.

     Section 8.07.    Binding Effect.  This Agreement shall become effective
when it shall have been executed by the Borrowers and the Administrative Agents
and when the U.S. Administrative Agent shall have, as to each Bank, either
received a copy of a signature page hereof executed by such Bank or been
notified by such Bank that such Bank has executed it and thereafter shall be
binding upon and inure to the benefit of the Borrowers, the Administrative
Agents and each Bank and their respective successors and assigns, except that
neither Borrower shall have the right to assign its rights hereunder or under
any other Loan Document or any interest herein or therein without the prior
written consent of all of the Banks.

     Section 8.08.    Assignments and Participations.  (a)  Each Bank may
assign to one or more banks or other entities all or a portion of its rights
and obligations under this Agreement (including, without limitation, all or a
portion of its Commitment, the Advances owing to it and the Notes held by it);
provided, however, that, except as provided in Section 8.08(g), (i) except with
respect to any assignment to an Affiliate, each Bank may enter into any such
assignment only if each of such Bank's Affiliates which is a Bank hereunder
simultaneously assigns to an Affiliate of the proposed assignee a percentage of
its Maximum Commitment equal to the percentage of the Maximum Commitment of
such Bank being assigned (for example, if a U.S. Bank assigns 40% and any
Affiliate of it is a Canadian Bank, each such Canadian Bank shall also assign
40%), (ii) and each such assignment shall be of a uniform, and not a varying,
percentage of all rights and obligations under and in respect of this
Agreement, (iii) except in the case of an assignment of all of a Bank's rights
and obligations under this Agreement or an assignment to another Bank, the
amount of the Commitment of the assigning Bank being assigned pursuant to each
such assignment (determined as of the date of the Assignment and Acceptance
with respect to such assignment) plus the amount of any Commitment of an
Affiliate of an assigning Bank being assigned pursuant to clause (i) of this
Section 8.08(a) shall in no event be less than the lesser of 3 1/2% of the
aggregate amount of the Commitments or U.S. $5,000,000, (iv) each such
assignment shall be to an Eligible Assignee or an Affiliate of a Bank that is
not an Investment Fund, (v) each such assignment to an Eligible Assignee (other
than an Affiliate of a Bank that is





                                     -111-
<PAGE>   117
not an Investment Fund) or to any Affiliate of a Bank that is not an Eligible
Assignee shall be subject to the consent of the U.S. Administrative Agent and
the U.S. Borrower, which consent shall not be unreasonably withheld, and (vi)
the assigning Bank and the assignee shall execute and deliver to the U.S.
Administrative Agent, for its acceptance and recording in the Register, an
Assignment and Acceptance, together with the Notes subject to such assignment
and a processing and recordation fee of $3,000; provided further, however, that
no assignment under this Section 8.08 shall result in any increase at the time
of such assignment in any amount payable by either Borrower hereunder
(including the withholding taxes which either Borrower is required to pay under
Section 2.12).  Upon such execution, delivery, acceptance and recording, from
and after the effective date specified in each Assignment and Acceptance, (x)
the assignee thereunder shall be a party hereto and, to the extent that rights
and obligations hereunder have been assigned to it pursuant to such Assignment
and Acceptance, have the rights and obligations of a Bank hereunder and (y) the
Bank assignor thereunder shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such Assignment and Acceptance,
relinquish its rights and be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all of an assigning
Bank's rights and obligations under this Agreement, such Bank shall cease to be
a party hereto).

     (b)      By executing and delivering an Assignment and Acceptance, the
Bank assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows:  (i) other than as provided
in such Assignment and Acceptance, such assigning Bank makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with any Loan Document
or any other instrument or document furnished pursuant hereto or in connection
herewith or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of any Loan Document or any other instrument or document
furnished pursuant hereto or in connection herewith; (ii) such assigning Bank
makes no representation or warranty and assumes no responsibility with respect
to the financial condition of either Borrower or any other Person or the
performance or observance by either Borrower or any other Person of any of its
respective obligations under any Loan Document or any other instrument or
document furnished pursuant hereto or in connection herewith; (iii) such
assignee confirms that it has received a copy of this Agreement, together with
copies of the Financial Statements and such other documents and information as
it has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Acceptance; (iv) such assignee will, independently and
without reliance upon either Administrative Agent, such assigning Bank or any
other Bank and based on such documents and information as it





                                     -112-
<PAGE>   118
shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement, any of the other Loan
Documents or any other instrument or document; (v) such assignee confirms that
it is an Eligible Assignee or an Affiliate of a Bank that is not an Investment
Fund; (vi) such assignee appoints and authorizes each Administrative Agent to
take such action as an Administrative Agent on its behalf and to exercise such
powers and discretion under the Loan Documents as are delegated to such
Administrative Agent by the terms hereof or thereof, together with such powers
and discretion as are reasonably incidental thereto; and (vii) such assignee
agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement are required to be performed
by it as a Bank.

     (c)      The U.S. Administrative Agent shall maintain at its address
referred to in Section 8.02 a copy of each Assignment and Acceptance delivered
to and accepted by it and a register for the recordation of the names and
addresses of the Banks and the Commitment of, and the principal amount of the
Advances owing to, each Bank from time to time (the "Register").  The entries
in the Register shall be conclusive and binding for all purposes, absent
manifest error, and the Borrower, each Administrative Agent and the Banks may
treat each Person whose name is recorded in the Register as a Bank hereunder
for all purposes of this Agreement.  The Register shall be available for
inspection by the Borrower or any Bank at any reasonable time and from time to
time upon reasonable prior notice.

     (d)      Upon its receipt of an Assignment and Acceptance executed by an
assigning Bank and an assignee representing that it is an Eligible Assignee or
an Affiliate of a Bank that is not an Investment Fund and consented to by the
U.S. Borrower and U.S. Administrative Agent where so required by this
Agreement, together with the Notes subject to such assignment, the U.S.
Administrative Agent shall, if such Assignment and Acceptance has been
completed and is in substantially the form of Exhibit H, (i) accept such
Assignment and Acceptance, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the Borrowers.  Within five
Business Days after its receipt of such notice, the Borrowers, at their
expense, shall execute and deliver to the Administrative Agent in exchange for
the surrendered Note a new Note payable to the order of such Eligible Assignee
in an amount equal to the Commitment assumed by it pursuant to such Assignment
and Acceptance and, if the assigning Bank has retained a Commitment hereunder,
a new Note payable to the order of the assigning Bank in an amount equal to the
Commitment retained by it hereunder (such new Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Notes, shall be dated the effective date of such Assignment and Acceptance and
shall otherwise be in substantially the form of Exhibits A or B as the case may
be).

     (e)      Each Bank may sell participations to one or more banks or other
entities (other than either Borrower or any of their respective Affiliates) in
or to all or a portion of its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment, the
Advances and other Accommodations owing to it and the Notes held by it);
provided that (i) such Bank's obligations under this Agreement (including,
without limitation, its Commitment to the Borrower hereunder) shall remain
unchanged, (ii) such Bank shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iii) such Bank shall remain
the holder of any such Notes for all purposes of this Agreement, (iv) the
Borrowers, the Administrative Agents and the other Banks shall continue to deal
solely and directly with such Bank in connection with such Bank's rights and
obligations under this Agreement, (v) the terms of any such participation shall
not restrict such Bank's ability to make any amendment or waiver of this
Agreement or any Note or such Bank's ability to consent to any departure by the
Borrowers therefrom without the approval of the participant, except that the
approval of the participant may be required to the extent that such amendment,
waiver or consent would release or impair the Guaranty, reduce the principal
of, or interest on, the Notes, the BA Obligations or any fees or other amounts
payable hereunder, in each case to the extent subject to such participation, or
postpone any date fixed for any payment of principal of, or interest on, the
Notes, the BA Obligations or any fees payable hereunder, in each case to the
extent subject to such participation, and (vi) no Participant shall have any
rights under this Agreement or any of the other Loan Documents, with each
participant's rights against the granting Bank in respect of any participation
to be those set forth in the participation agreement, and all amounts payable
by the Borrower hereunder shall be determined as if such Bank had not granted
such participation.

     (f)      Any Bank may, in connection with any assignment or participation
or proposed assignment or participation pursuant to this Section 8.08, disclose
to the assignee or participant or proposed assignee or participant, any
information relating to either Borrower or any Subsidiary of either Borrower
furnished to such Bank by or on behalf of either Borrower or any such
Subsidiary; provided, that, prior to any such disclosure, the assignee or
participant or proposed assignee or participant shall agree for the benefit of
the Borrowers and such Bank to comply with Section 8.13.

     (g)      Notwithstanding any other provision set forth in this Agreement,
any Bank may at any time create a security interest in all or any portion of
its rights under this Agreement (including the Advances owing to it and the
Note or Notes held by it) in favor of any Federal Reserve Bank in accordance
with Regulation A of the Board of Governors of the Federal Reserve System, but
no such assignment shall release such Bank from its





                                     -114-

obligations hereunder.

     Section 8.09.    Execution in Counterparts.  This Agreement may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.  Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be as effective as delivery of a manually

     Section 8.10.    Governing Law.  This Agreement and the Notes shall be
governed by, and construed in accordance with, the laws of the State of New
York.  Without limiting the intent of the parties set forth above, (i) Chapter

agrees that it will use reasonable efforts not to disclose any Confidential

such Bank or Administrative Agent of, or is aware of, the confidential nature
thereof and that is bound, for the benefit of the Borrowers and such Bank or
Administrative Agent, by the terms and conditions hereof and that is bound, for
the benefit of the Borrowers and such Bank or Administrative Agent, to not use
any such Confidential Information except for the purposes of the Loan Documents
and the Accommodations, provided that in the event of any disclosure of
Confidential Information pursuant to either of clauses (c) and (d) of this
Section 8.13, such Administrative Agent or Bank making such disclosure shall
make a good faith attempt, to the extent practicable, to notify the U.S.
Borrower of any such disclosure of such Confidential Information at least three
U.S. Business Days prior to such disclosure, and in any event shall notify the
U.S. Borrower of such disclosure as soon as practicable, but no notice shall be
required pursuant to this proviso if giving such notice would conflict with any
law, order, regulation or ruling.

     Section 8.14.    Judgment Currency.  (a) If, for the purposes of obtaining
judgment in any court, it is necessary to convert any sum due or owing
hereunder or under the Guaranty or any other Loan Document to either
Administrative Agent or any one or more of the Banks in any currency (the
"Original Currency") into another currency (the "Other Currency"), the parties
hereto agree, to the fullest extent that they may effectively do so, that the
rate of exchange used shall be that at which in accordance with normal banking
procedures such Administrative Agent or Bank, as the case may be, could
purchase the Original Currency with the Other Currency on the Business Day
preceding that on which final judgment is granted, together with any premiums
and costs of exchange payable in connection with such purchase.

     (b)      The obligations of the Borrowers in respect of any sum due in the
Original Currency from it to either Administrative Agent or any Bank under any
of the Loan Documents shall, notwithstanding any judgment in any Other
Currency, be discharged only to the extent that on the Business Day following
receipt by such Administrative Agent or Bank, as the case may be, of any sum
adjudged to be so due or owing in such Other Currency, such Administrative
Agent or Bank, as the case may be, may in accordance with normal banking
procedures purchase the Original Currency with such Other Currency.  IF THE
AMOUNT OF THE ORIGINAL CURRENCY SO PURCHASED IS LESS THAN THE SUM ORIGINALLY
DUE OR OWING TO SUCH ADMINISTRATIVE AGENT OR BANK, AS THE CASE MAY BE, IN THE
ORIGINAL CURRENCY, EACH BORROWER AGREES, AS A SEPARATE OBLIGATION AND
NOTWITHSTANDING ANY SUCH JUDGMENT, TO INDEMNIFY SUCH ADMINISTRATIVE AGENT OR
SUCH BANK, AS THE CASE MAY BE, AGAINST SUCH LOSS, AND IF THE AMOUNT OF THE
ORIGINAL CURRENCY SO PURCHASED EXCEEDS THE SUM ORIGINALLY DUE OR OWING TO SUCH
ADMINISTRATIVE AGENT OR SUCH BANK, AS THE CASE MAY BE, IN THE ORIGINAL
CURRENCY, SUCH ADMINISTRATIVE AGENT OR SUCH BANK, AS THE CASE MAY BE, SHALL
REMIT SUCH EXCESS
