     with the Agent amounts equal to the maximum amount of the relevant
     Documentary Instruments (in each case in the respective
<PAGE>

                                      -28-

     currency in which the relevant Loans are denominated); such amounts
     deposited by the Borrower shall belong to the Borrower and shall be held by
     the Agent in interest bearing cash collateral accounts with interest to be
     credited to the Borrower at rates prevailing at the time of deposit. Such
     cash collateral accounts shall be assigned to the Agent as security for the
     obligations of the Borrower in relation to such Documentary Instruments and
     the Security Interest of the Agent thereby created in such cash collateral
     shall rank in priority to all other Security Interests and adverse claims
     against such cash collateral. Such cash collateral shall be applied to
     satisfy the obligations of the Borrower for such Documentary Instruments as
     payments are made thereunder and the Agent is hereby irrevocably directed
     by the Borrower to so apply any such cash collateral. Amounts held in such
     cash collateral accounts may not be withdrawn by the Borrower without the
     consent of the Lenders; however, interest on such deposited amounts shall
     be for the account of the Borrower and may be withdrawn by the same. If
     after maturity or expiry, as the case may be, of the Loans for which such
     funds are held and application by the Agent of the amounts in such cash
     collateral accounts to satisfy the obligations of the Borrower hereunder
     with respect to the Loans being repaid, any excess remains, such excess
     shall be promptly paid by the Agent to the Borrower.

2.13 Mandatory Repayment

     Subject to Section 11.2, all Obligations owing hereunder shall be repaid or
paid, as the case may be, by the Borrower on or before the Maturity Date.

2.14 Currency Excess

     (1) The Agent shall determine the Outstanding Principal as at the day of
     any requested reduction or cancellation of the Credit Facility, on any
     Drawdown or Conversion (after giving effect to the requested Drawdown and
     any actual or notional repayment of Loans on the proposed Drawdown Date or
     Conversion Date) and as at the last Banking Day of each calendar month in
     each year, and on any other day selected by the Agent in its sole
     discretion (each, a "Currency Test Date").  If on a Currency Test Date the
     aggregate Outstanding Principal exceeds or would exceed the Borrowing Base,
     after giving effect to any reductions thereto on such date (the amount of
     such excess is herein called the "Currency Excess"), and such Currency
     Excess remains unremedied for a period of 3 Business Days, then upon the
     request in writing of the Agent (which request shall detail the applicable
     Currency Excess) the Borrower shall, in the sole discretion of the Lenders
     acting reasonably, either: (i) reduce the amount of requested Loans on such
     date or repay an amount of Canadian Prime Rate Loans or Alternate Base Rate
     Loans within 30 Banking Days after receipt of such request, or a
     combination of the foregoing, such that, except as otherwise contemplated
     in Section 2.14(2), the Equivalent Amount in United States Dollars of the
     reductions or payments is, in the aggregate, at least equal to the Currency
     Excess; (ii) provide additional collateral, of character and value
     satisfactory to the Lenders in their sole discretion acting reasonably, to
     secure the Obligations by the execution and delivery to the Lenders of
     security instruments in form and substance satisfactory to the Lenders
     acting reasonably, or (iii) effect any
<PAGE>

                                      -29-

     combination of the alternatives described in clauses (i) and (ii) of this
     Section and acceptable to the Lenders in their sole discretion acting
     reasonably.

     (2)  If, in respect of any Currency Excess existing as at any Currency Test
     Date, the actions taken by the Borrower in accordance with Section 2.14(1)
     have not completely removed such Currency Excess (the remainder thereof
     being herein called the "Currency Excess Deficiency"), the Borrower shall,
     within 5 Banking Days after such Currency Test Date, place an amount equal
     to the Currency Excess Deficiency on deposit with the Agent in an interest-
     bearing account in the Borrower's name with interest at rates prevailing at
     the time of deposit for the account of the Borrower, to be assigned to the
     Agent by instrument satisfactory to the Agent and to be applied to
     Documentary Instruments as payments are made thereunder (converted if
     necessary at the exchange rate for determining the Equivalent Amount on the
     date of such application).  The Agent is hereby irrevocably directed by the
     Borrower to apply any such sums on deposit to Loans as provided in the
     preceding sentence. In lieu of providing funds for the Currency Excess
     Deficiency, as provided in the preceding provisions of this Section
     2.14(2), the Borrower may within the said period of 5 Banking Days provide
     to the Agent an irrevocable standby letter of credit in an amount equal to
     the Currency Excess Deficiency and for a term which expires not sooner than
     10 Banking Days after the expiry of the relevant Documentary Instruments,
     such letter of credit shall be issued by a financial institution and shall
     be on terms and conditions acceptable to the Agent in its sole discretion.
     The Agent is hereby authorized and directed to draw upon such letter of
     credit and apply the proceeds of the same to Documentary Instruments as
     payments are made thereunder.  Upon the Currency Excess being eliminated as
     aforesaid or by virtue of subsequent changes in the exchange rate for
     determining the Outstanding Principal, such funds on deposit, together with
     interest thereon, or such letters of credit shall be returned to the
     Borrower, in the case of funds on deposit, or shall be cancelled or reduced
     in amount, in the case of letters of credit.

2.15 Takeover Notification

     The Agent shall have no obligation to make Drawdowns for the purpose of
enabling the Borrower (either directly or indirectly, through a Subsidiary or
otherwise) to acquire shares of a publicly traded corporation, the acquisition
of which requires disclosure pursuant to the requirements of applicable
securities law or any securities commission or exchange or other Governmental
Authority having jurisdiction over the sale or the issuance of securities of the
Borrower or such publicly traded corporation, if the Agent determines (in its
sole discretion having regard to such considerations as it deems appropriate)
that the utilization of Drawdowns for such purpose would result in it being in a
conflict of interest.  At least 5 Banking Days prior to the giving of any notice
pursuant to Section 2.5 requesting Drawdowns intended to be utilized for such
purpose, the Borrower shall provide, in strict confidence, details of such
proposed acquisition (including the name of such publicly traded corporation) to
the Agent so that the Agent can make the determination referred to above;
provided that, such details shall be made available by the Agent only to persons
that need to know such details in order to make such determination.  The Agent
shall advise the
<PAGE>

                                      -30-

Borrower whether such conflict of interest exists within 3 Banking Days after
receipt from the Borrower of such details. Failure by the Agent to so advise the
Borrower of a conflict shall be deemed to be a determination that no conflict
exists for the Agent.

2.16 Determination of Borrowing Base

     (a)  the Borrowing Base as of August 1, 2000, is acknowledged by the
          Borrower and the Lenders to be U.S. $10,815,000 (the "Initial
          Borrowing Base").  Commencing on September 1, 2000, and continuing
          thereafter on the first day of each calendar month through the
          Maturity Date, the amount of the Borrowing Base shall be reduced by
          U.S. $185,000;

     (b)  the Borrowing Base shall be redetermined semi-annually by unanimous
          consent of the Lenders beginning December 1, 2000 (and on the first
          days of June and December thereafter), on the basis of information
          supplied by the Borrower in compliance with the provisions of this
          Agreement, including, without limitation, Engineering Reports, and all
          other information available to the Lenders.  In addition, the Lenders
          shall, in the normal course of business following a request of the
          Borrower, redetermine the Borrowing Base; provided, however, the
          Lenders shall not be obligated to respond to more than four such
          requests during any calendar year, and in no event shall the Lenders
          be required to redetermine the Borrowing Base more than once in any
          three-month period, including, without limitation, each scheduled
          semi-annual redetermination provided for above.  Notwithstanding the
          foregoing, the Lenders may at their discretion and by unanimous
          consent redetermine the Borrowing Base and the amount by which the
          Borrowing Base shall be reduced each calendar month as set forth in
          Section 2.16(a) at any time and from time to time.

     (c)  upon each determination of the Borrowing Base by the Lenders, the
          Agent shall notify the Borrower orally (confirming such notice
          promptly in writing) of such determination, and the Borrowing Base and
          the amount by which the Borrowing Base shall be reduced or increased
          so communicated to the Borrower shall become effective upon such
          written notification and shall remain in effect until the next
          subsequent determination of the Borrowing Base and the amount by which
          the Borrowing Base shall be reduced.

     (d)  the Borrowing Base shall represent the determination by the Lenders,
          in accordance with the applicable definitions and provisions herein
          contained, their then current engineering standards and their then
          current and customary lending standards for loans of this nature, of
          the value, for loan purposes, of the Mortgaged Properties, subject, in
          the case of any increase in the Borrowing Base, to the credit approval
          process of the Lenders.  Furthermore, the Borrower acknowledges that
          the determination of the Borrowing Base contains an equity cushion
          (market value in
<PAGE>

                                      -31-

          excess of loan value), which is acknowledged by the Borrower to be
          essential for the adequate protection of the Lenders.

                             EVIDENCE OF DRAWDOWNS

4.1  Account of Record

     The Agent shall open and maintain books of account evidencing all Loans and
all other amounts owing by the Borrower to the Lenders hereunder.  The Agent
shall enter in the foregoing accounts details of all amounts from time to time
owing, paid or repaid by the Borrower hereunder.  The information entered in the
foregoing accounts shall, absent manifest error, constitute prima facie evidence
of the obligations of the Borrower to the Lenders hereunder with respect to all
Loans and all other amounts owing by the Borrower to the Lenders hereunder.
After a request by the Borrower, the Agent shall promptly advise the Borrower of
such entries made in the Agent's books of account.

                         PAYMENTS OF INTEREST AND FEES

5.1  Interest on Canadian Prime Rate Loans

     The Borrower shall pay interest on each Canadian Prime Rate Loan owing by
it during each Interest Period applicable thereto in Canadian Dollars at a rate
per annum equal to the Canadian Prime Rate in effect from time to time during
such Interest Period plus the Applicable Margin.  Each determination by the
Agent of the Canadian Prime Rate applicable from time to time during an Interest
Period shall, in the absence of manifest error, be conclusive evidence thereof.
Such interest shall accrue daily and shall be payable in arrears on each
Interest Payment Date for such Loan for the period from and including the
Drawdown Date or the preceding Conversion Date or Interest Payment Date, as the
case may be, for such Loan to and including the day preceding such Interest
Payment Date and shall be calculated on the principal amount of the Canadian
Prime Rate Loan outstanding during such period and on the basis of the actual
number of days elapsed in a year of 365 days or 366 days, as the case may be.
Changes in the Canadian Prime Rate shall cause an immediate adjustment of the
interest rate applicable to such Loan without the necessity of any notice to the
Borrower.

5.2  Interest on Alternate Base Rate Loans

     The Borrower shall pay interest on each Alternate Base Rate Loan owing by
it during each Interest Period applicable thereto in United States Dollars at a
rate per annum, calculated on the basis of a 365 day year, equal to the
Alternate Base Rate in effect from time to time during such Interest Period plus
the Applicable Margin.  Each determination by the Agent of the Alternate Base
Rate applicable from time to time during an Interest Period shall, in the
absence of manifest error, be conclusive evidence thereof.  Such interest shall
be payable in arrears on each Interest Payment Date for such Loan for the period
from and including the Drawdown Date or the preceding Conversion Date or
Interest Payment Date, as the case may be, for such Loan to and including the
day preceding
<PAGE>

                                      -34-

such Interest Payment Date and shall be calculated on the principal amount of
the Alternate Base Rate Loan outstanding during such period and on the basis of
the actual number of days elapsed divided by 365. Changes in the Alternate Base
Rate shall cause an immediate adjustment of the interest rate applicable to such
Loan without the necessity of any notice to the Borrower.

5.3  Per Annum Calculations

     Unless otherwise stated, wherever in this Agreement reference is made to a
rate of interest "per annum" or a similar expression is used, such interest
shall be calculated on the basis of a calendar year of 365 days or 366 days, as
the case may be.

5.4  Interest Act (Canada)

     Whenever a rate of interest hereunder is calculated on the basis of a year
(the "deemed year") which contains fewer days than the actual number of days in
the calendar year of calculation, such rate of interest shall be expressed as a
yearly rate for purposes of the Interest Act (Canada) by multiplying such rate
of interest by the actual number of days in the calendar year of calculation and
dividing it by the number of days in the deemed year.

5.5  Nominal Rates; No Deemed Reinvestment

     The principle of deemed reinvestment of interest shall not apply to any
interest calculation under this Agreement; all interest payments to be made
hereunder shall be paid without allowance or deduction for deemed reinvestment
or otherwise, before and after maturity, default and judgment. The rates of
interest specified in this Agreement are intended to be nominal rates and not
effective rates.  Interest calculated hereunder shall be calculated using the
nominal rate method and not the effective rate method of calculation.

5.6  Stand-By Fees

     (1)  The Borrower shall pay to the Agent for the account of the Lenders a
     stand-by fee in United States Dollars calculated at the rate of 0.50% per
     annum on the amount, if any, by which the amount of the Outstanding
     Principal for each day in the period of determination is less than the
     amount for each such day of the Borrowing Base.  Fees determined in
     accordance with this Section shall accrue daily from and after the date
     hereof and be payable by the Borrower quarterly in arrears and on
     cancellation in full of the Credit Facility or the Maturity Date.

     (2)  As of: (a) January 1, April 1, July 1 and October 1 in each year, (b)
     the date of any cancellation in full of the Credit Facility, and (c) the
     Maturity Date, the Agent shall determine the stand-by fees under this
     Section for the period from and including the date hereof or the date of
     the immediately preceding determination, as the case may be, to but
     excluding that date of determination and shall deliver to the Borrower a
     written request for
<PAGE>

                                      -35-

     payment of the stand-by fees so determined, as detailed therein. The
     Borrower shall pay to the Agent for the account of the Lenders the stand-by
     fees referred to above within 5 Banking Days after receipt of each such
     written request.

5.7  Facility Fee

     The Borrower shall pay to the Agent on or before the date hereof a facility
fee in United States Dollars equal to 0.50% of the Initial Borrowing Base, of
which U.S. $13,750 has already been paid by the Borrower to the Agent and the
Agent hereby acknowledges receipt thereof.  The Borrower shall pay to the Agent
on the date of each and every increase in the Borrowing Base, a further facility
fee in United States Dollars equal to .50% of such increase in the Borrowing
Base. The Agent shall determine the facility fees payable under this Section on
or prior to the foregoing dates and shall deliver to the Borrower a written
request for payment of the facility fee so determined, as detailed therein.

5.8  Engineering Fees

     The Borrower shall pay to the Agent on or before the date of each
redetermination of the Borrowing Base an engineering fee in the amount of U.S.
$10,000.

5.9  Interest on Overdue Amounts

     In the event that any amount due hereunder (including, without limitation,
any interest payment) is not paid when due (whether by acceleration or
otherwise), the Borrower shall pay interest on such unpaid amount (including,
without limitation, interest on interest), if and to the fullest extent
permitted by applicable law, from the date that such amount is due until the
date that such amount is paid in full (but excluding the date of such payment if
the payment is received for value at the required place of payment on the date
of such payment), and such interest shall accrue daily, be calculated and
compounded monthly and be payable on demand, after as well as before maturity,
default and judgment, at a rate per annum that is equal to (a) in respect of
amounts due in Canadian Dollars, the interest rate applicable hereunder to
Canadian Prime Rate Loans plus 5.0% per annum or (b) in respect of amounts due
in United States Dollars, the interest rate applicable hereunder to Alternate
Base Rate Loans plus 5.0% per annum.

5.10 Waiver

     To the extent permitted by applicable law, the covenant of the Borrower to
pay interest at the rates provided herein shall not merge in any judgment
relating to any obligation of the Borrower to the Lenders or the Agent. To the
extent permitted by applicable law, any provision of the Interest Act (Canada),
Judgment Interest Act (Alberta), Pre-Judgment Interest Act (Saskatchewan),
Executions Act (Saskatchewan) or other similar legislation which restricts any
rate of interest set forth herein shall be inapplicable to this Agreement and is
hereby waived by the Borrower.
<PAGE>

                                      -36-

5.11 Maximum Rate Permitted by Law

     No interest or fee to be paid hereunder shall be paid at a rate exceeding
the maximum rate permitted by applicable law.  In the event that such interest
or fee exceeds such maximum rate, such interest or fees shall be reduced or
refunded, as the case may be, so as to be payable at the highest rate
recoverable under applicable law.


                                   ARTICLE 6
                            DOCUMENTARY INSTRUMENTS

6.1  Availability

     Subject to the provisions hereof, the Issuing Lender shall issue, renew or
extend Documentary Instruments under the Credit Facility in accordance with the
Drawdown Notices of the Borrower; provided that the aggregate outstanding
Principal represented by all outstanding Documentary Instruments shall not
exceed U.S. $500,000 or the Equivalent Amount in Canadian Dollars.  The issuance
of Documentary Instruments shall constitute Drawdowns hereunder and shall reduce
the availability of the Credit Facility by the amount of such Documentary
Instruments.

6.2  Form

     Documentary Instruments shall be in a form satisfactory to the Issuing
Lender and shall have an expiration date not in excess of one year from the date
of issue.

6.3  No Conversion

     Except as provided in Section 6.4, the Borrower may not effect a Conversion
of a Documentary Instrument.

6.4  Reimbursement or Conversion on Presentation; Issuing Lender Indemnity

     (1)  On presentation of a Documentary Instrument and payment thereunder by
          the Issuing   Lender, the Borrower shall forthwith pay to and
          reimburse the Issuing Lender for all amounts paid by the Issuing
          Lender pursuant to such Documentary Instrument; failing such payment,
          the Borrower shall be deemed to have effected a Conversion of such
          Documentary Instrument into: (a) a Canadian Prime Rate Loan, in the
          case of a Documentary Instrument denominated in Canadian Dollars; and
          (b) an Alternate Base Rate Loan, in the case of a Documentary
          Instrument denominated in United States Dollars, in each case to the
          extent of the payment of the Issuing Lender thereunder.
<PAGE>

                                      -37-


     (2)  (a)  If the Issuing Lender makes payment under any Documentary
               Instrument and the Borrower does not fully reimburse the Issuing
               Lender on or before the date of payment, then Section 6.4(1)
               shall apply to deem a Loan to be outstanding to the Borrower
               under this Agreement in the manner therein set out. Each Lender
               shall, on request by the Issuing Lender, immediately pay to the
               Issuing Lender an amount equal to such Lender's Rateable Portion
               of the amount paid by the Issuing Lender such that each Lender is
               participating in the deemed Loan in accordance with its Rateable
               Portion.

          (b)  Each Lender shall immediately on demand indemnify the Issuing
               Lender to the extent of such Lender's Rateable Portion of any
               amount paid or liability incurred by the Issuing Lender under
               each Documentary Instrument issued by it to the extent that the
               Borrower does not full reimburse the Issuing Lender therefor.

          (c)  For certainty, the obligations in this Section 6.4(2) shall
               continue as obligations of the persons who were Lenders at the
               time each such Documentary Instrument was issued notwithstanding
               that such Lender may assign its rights and obligations hereunder,
               unless the Issuing Lender specifically releases such Lender from
               such obligations in writing.

6.5  Fees

     The Borrower shall pay to the Issuing Lender for the account of all Lenders
an issuance fee (in the currency which the Documentary Instrument is
denominated) in advance on the date each Documentary Instrument is issued equal
to the greater of $500, or one percent (1%) per annum, calculated on the basis
of a year of 365 or 366, as the case may be, and actual days elapsed (including
the first day but excluding the last), on the face amount of such Documentary
Instrument during the period for which such Documentary Instrument is issued;
provided however, in the event such Documentary Instrument is cancelled prior to
its original expiry date or a payment is made by the Issuing Lender with respect
to such Documentary Instrument, the Issuing Lender shall, within 30 days after
such cancellation or the making of such payment, rebate the Borrower the
unearned portion of such fee.  In addition, with respect to all Documentary
Instruments the Borrower shall from time to time pay to the Issuing Lender its
usual and customary fees (at the then prevailing rates) for the amendment,
delivery and administration of letters of credit and letters of guarantee such
as the Documentary Instruments.

6.6  Additional Provisions

     (a)  Indemnity and No Lender Liability
          ---------------------------------

          The Borrower shall indemnify and save harmless the Lenders, the
          Issuing Lender and the Agent against all claims, losses, costs,
          expenses or damages to the Lenders, Issuing Lender or Agent arising
          out of or in connection with any Documentary Instrument, the issuance
          thereof, any payment thereunder or any action taken by the Lenders,
          the Issuing Lender or the Agent or any other person in connection
          therewith, including, without limitation, all costs relating to any
          legal process or proceeding instituted by any party restraining or
          seeking to restrain the Issuing Lender from accepting or paying any
          Draft or any amount under any such Documentary Instrument, but
          excepting from the foregoing those which result from the Agent's or a
          Lender's gross negligence or wilful misconduct. The Borrower also
          agrees that the Lenders, the Issuing Lender and the Agent shall have
          no liability to it for any reason in respect of or in connection with
          any Documentary Instrument, the issuance thereof, any payment
          thereunder or any other action taken by the Lenders, or any other
          person in connection therewith, except as a result of the Lenders',
          Issuing Lender's or Agent's gross negligence or wilful misconduct.

     (b)  No Obligation to Inquire
          ------------------------

          The Borrower hereby acknowledges and confirms to the Issuing Lender
          that the Issuing Lender shall not be obliged to make any inquiry or
          investigation as to the right of any beneficiary to make any claim or
          Draft or request any payment under a Documentary Instrument and
          payment by the Issuing Lender pursuant to a Documentary Instrument
          shall not be withheld by the Issuing Lender by reason of any matters
          in dispute between the beneficiary thereof and the Borrower. The sole
          obligation of the Issuing Lender with respect to Documentary
          Instruments is to cause to be paid a Draft drawn or purporting to be
          drawn in accordance with the terms of the applicable Documentary
          Instrument and for such purpose the Issuing Lender is only obliged to
          determine that the Draft purports to comply with the terms and
          conditions of the relevant Documentary Instrument.

          The Issuing Lender shall not have any responsibility or liability for
          or any duty to inquire into the form, sufficiency (other than to the
          extent provided in the preceding paragraph), authorization, execution,
          signature, endorsement, correctness (other than to the extent provided
          in the preceding paragraph), genuineness or legal effect of any Draft,
          certificate or other document presented to it pursuant to a
          Documentary Instrument and the Borrower unconditionally assumes all
          risks with respect to the same. The Borrower agrees that it assumes
          all risks of the acts or omissions of the beneficiary of any
          Documentary Instrument with respect to the use by such beneficiary of
          the relevant Documentary Instrument.
<PAGE>

                                      -39-

     (c)  The obligations of a Borrower hereunder with respect to all
          Documentary Instruments shall be absolute, unconditional and
          irrevocable and shall not be reduced by any event, circumstance or
          occurrence including, without limitation, any lack of validity or
          enforceability of a Documentary Instrument, or any Draft paid or acted
          upon by the Issuing Lender or any of its correspondents being
          fraudulent, forged, invalid or insufficient in any respect, or any
          defenses or claims which the Borrower may have against any beneficiary
          or transferee of any Documentary Instrument. The obligations of a
          Borrower hereunder shall remain in full force and effect and shall
          apply to any alteration to or extension of the expiration date of any
          Documentary Instrument or any letter of credit or letter of guarantee
          issued to replace, extend or alter any Documentary Instrument.

     (d)  Issuing Lender Actions
          ----------------------

          Any action, inaction or omission taken or suffered by the Issuing
          Lender or by any of the Issuing Lender's correspondents under or in
          connection with a Documentary Instrument or any Draft made thereunder,
          if in good faith and in conformity with foreign or domestic laws,
          regulation or customs applicable thereto shall be binding upon the
          Borrower and shall not place the Issuing Lender or any of its
          correspondents under any resulting liability to the Borrower. Without
          limiting the generality of the foregoing, the Issuing Lender and its
          correspondents may receive, accept or pay as complying with the terms
          of a Documentary Instrument, any Draft thereunder, otherwise in order
          which may be signed by, or issued to, the administrator or any
          executor of, or the trustee in bankruptcy of, or the receiver for any
          property of, or any person or entity acting as a representative or in
          the place of, such beneficiary or its successors and assigns. The
          Borrower covenants that it will not take any steps, issue any
          instructions to the Issuing Lender or any of its correspondents or
          institute any proceedings intended to derogate from the right or
          ability of the Issuing Lender or its correspondents to honour and pay
          any Documentary Instrument or any Drafts.

     (e)  Payment of Contingent Liabilities
          ---------------------------------

          The Borrower shall pay to the Issuing Lender an amount equal to the
          maximum amount available to be drawn under any unexpired Documentary
          Instrument which becomes the subject of any order, judgment,
          injunction or other such determination (an "Order"), or any petition,
          proceeding or other application for any Order by the Borrower or any
          other party, restricting payment by the Issuing Lender under and in
          accordance with such Documentary Instrument or extending the Issuing
          Lender's liability under such Documentary Instrument beyond the
          expiration date stated therein (a "Proceeding"); payment in respect of
          each such Documentary Instrument shall be due forthwith upon demand in
          the currency in which such Documentary Instrument is denominated.
<PAGE>

                                      -40-

          Any amount paid to the Issuing Lender pursuant to the preceding
          paragraph shall be held by the Issuing Lender in interest bearing cash
          collateral accounts (with interest payable for the account of the
          Borrower at the rates and in accordance with the then prevailing
          practices of the Issuing Lender for accounts of such type) as
          continuing security for the Obligations and shall, prior to an Event
          of Default be applied by the Issuing Lender against the Obligations
          for, or (at the option of the Issuing Lender) be applied in payment
          of, such Documentary Instrument if payment is required thereunder;
          after an Event of Default the Issuing Lender may apply such amounts
          against any Obligations as it sees fit.

          The Issuing Lender shall release to the Borrower any amount remaining
          in the cash collateral accounts after applying the amounts necessary
          to discharge the Obligations relating to such Documentary Instrument,
          upon the later of:

          (i)    if the Documentary Instrument is subject to an Order or is the
                 subject of an outstanding Proceeding, the date on which any
                 final and non-appealable order, judgment or other determination
                 has been rendered or issued either terminating any applicable
                 Order or Proceeding or permanently enjoining the Issuing Lender
                 from paying under such Documentary Instrument or, in the case
                 of a Proceeding, it has been terminated by the agreement of the
                 parties thereto;

          (ii)   the earlier of:

                 A.   the date on which either the original counterpart of such
                      Documentary Instrument is returned to the Issuing Lender
                      for cancellation or the Issuing Lender is released by the
                      beneficiary thereof from any other obligation in respect
                      of such Documentary Instrument; and

                 B.   the expiry of such Documentary Instrument; and

          (iii)  if an Event of Default has occurred and is continuing, the
                 payment and satisfaction of all Obligations and the
                 cancellation or termination of the Credit Facility.

     (f)  Uniform Customs and Practice
          ----------------------------

          The Uniform Customs and Practice for Documentary Credits as most
          recently published by the International Chamber of Commerce (the
          "Uniform Customs") shall in all respects apply to each Letter of
          Credit unless expressly provided to the contrary therein and shall be
          deemed for such purpose to be a part of this Agreement as if fully
          incorporated herein. In the event of any conflict or inconsistency
          between the Uniform Customs and the governing law of this Agreement,
          the Uniform Customs
<PAGE>

                                      -41-

          shall, to the extent permitted by applicable law, prevail to the
          extent necessary to remove the conflict or inconsistency.

7.1  Place of Payment of Principal, Interest and Fees; Payments to Agent

     All payments of principal, interest, fees and other amounts to be made by
the Borrower to the Agent and the Lenders pursuant to this Agreement shall be
made to the Agent (for, as applicable, the account of the Lenders or its own
account) in the currency in which the Loan is outstanding for value on the day
such amount is due, and if such day is not a Banking Day on the Banking Day next
following, by deposit or transfer thereof to the account or accounts of the
Agent maintained at the Agent's Branch and designated by the Agent for such
purpose or at such other place as the Borrower and the Agent may from time to
time agree.  Notwithstanding anything to the contrary expressed or implied in
this Agreement, the receipt by the Agent in accordance with this Agreement of
any payment made by the Borrower for the account of any of the Lenders shall,
insofar as the Borrower's obligations to the relevant Lenders are concerned, be
deemed also to be receipt by such Lenders and the Borrower shall have no
liability in respect of any failure or delay on the part of the Agent in
disbursing and/or accounting to the relevant Lenders in regard thereto.

7.2  Designated Accounts of the Lenders

     All payments of principal, interest, fees or other amounts to be made by
the Agent to the Lenders pursuant to this Agreement shall be made for value on
the day required hereunder, provided the Agent receives funds from the Borrower
for value on such day, and if such funds are not so received from the Borrower
or if such day is not a Banking Day, on the Banking Day next following, by
deposit or transfer thereof at the time specified herein to the account of each
Lender designated by such Lender to the Agent for such purpose or to such other
place or account as the Lenders may from time to time notify the Agent.

7.3  Funds

     Each amount advanced, disbursed or paid hereunder shall be advanced,
disbursed or paid, as the case may be, in such form of funds as may from time to
time be customarily used for Canadian Dollars in Calgary, Alberta and Toronto,

     (c)  to amounts due hereunder as stand-by fees;

     (f)  to amounts due hereunder as principal.

7.5  Set Off

     (1)  The Obligations shall be paid by the Borrower without any set-off,
     withholding or deduction whatsoever.

     (2)  In addition to any rights now or hereafter granted under applicable
     law and not by way of limitation of any such rights, upon the occurrence of
     an Event of Default which remains unremedied (whether or not the Loans have
     been accelerated hereunder), the Agent and each Lender shall have the right
     (and are hereby authorized by the Borrower) at any time and from time to
     time to combine all or any of the Borrower's accounts with the Agent or the
     Lenders, as the case may be, and to set off and to appropriate and to apply
     any and all deposits (general or special, term or demand) including, but
     not limited to, indebtedness evidenced by certificates of deposit whether
     matured or unmatured, and any other indebtedness at any time held by the
     Borrower or owing by such Lender or the Agent, as the case may be, to or
     for the credit or account of the Borrower against and towards the
     satisfaction of any Obligations, and may do so notwithstanding that the
     balances of such accounts and the liabilities are expressed in different
     currencies, and the Agent and each Lender are hereby authorized to effect
     any necessary currency conversions at the noon spot rate of exchange
     announced by the Bank of Canada on the Banking Day before the day of
     conversion.

     (3)  The Agent or the applicable Lender, as the case may be, shall notify
     the Borrower of any such set-off from the Borrower's accounts within a
     reasonable period of time thereafter, although the Agent or the Lender, as
     the case may be, shall not be liable to the Borrower for its failure to so
     notify.

                                   ARTICLE 8
                        REPRESENTATIONS AND WARRANTIES

8.1  Representations and Warranties

     The Borrower hereby represents and warrants as follows to the Agent and the
Lenders and acknowledges and confirms that the Agent and the Lenders are relying
upon such representations and warranties:

     (a)  Corporate Status
          ----------------

          The Borrower is a corporation duly incorporated and validly existing
          under the laws of the Province of Alberta and has all necessary
          corporate power and authority to own its properties and carry on its
          business as presently carried on and is duly licensed, registered or
          qualified in all jurisdictions where the character of its property
          owned or leased or the nature of the activities conducted by it makes
          such licensing, registration or qualification necessary.

     (b)  Corporate Authority
          -------------------

          The Borrower has full corporate power and authority to enter into this
          Agreement and the Documents to which it is a party and to do all acts
          and execute and deliver all other documents as are required hereunder
          or thereunder to be done, observed or performed by it in accordance
          with their respective terms.

     (c)  Valid Authorization
          -------------------

          The Borrower has taken all necessary corporate and other action to
          authorize the creation, execution, delivery and performance of this
          Agreement and the other Documents and to observe and perform the
          provisions of each in accordance with their respective terms.

     (d)  Validity of Documents and Enforceability; No Resulting Violation
          ----------------------------------------------------------------

          This Agreement constitutes and, when executed and delivered, each of
          the Documents will constitute valid and legally binding obligations of
          the Borrower enforceable against it in accordance with their
          respective terms subject to applicable bankruptcy, insolvency and
          other laws of general application limiting the enforceability of
          creditors' rights and to the fact that specific performance is an
          equitable remedy available only in the discretion of the court.
          Neither the execution and delivery of this Agreement or any other
          Document, nor compliance with the
<PAGE>

                                      -44-

          terms and conditions of any of them, (i) has resulted or will result
          in a violation of the articles or the by-laws of the Borrower or any
          resolutions passed by the directors or shareholders of the Borrower or
          any applicable law, rule, regulation, order, judgment, injunction,
          award or decree, (ii) has resulted or will result in a material breach
          of, or constitute a default under, any material loan agreement,
          indenture, trust deed or any other material agreement or instrument to
          which the Borrower is a party or by which it is bound, (iii) requires
          any material approval or consent of any Governmental Authority having
          jurisdiction except such as has already been obtained, or (iv) has
          resulted or will result in the creation of or the obligation to create
          any material Security Interest on, against or in respect of any of the
          material property, assets and undertakings of the Borrower and its
          Material Subsidiaries except as permitted or contemplated hereby.

     (e)  Title to Assets
          ---------------

          (i)    No person has any agreement or right to acquire any of the
                 assets of the Borrower or any of its Material Subsidiaries or
                 any interest therein other than with respect to Permitted
                 Dispositions.

          (ii)   The Borrower and each of its Material Subsidiaries have good
                 title to their assets, subject to Permitted Title Defects and
                 Permitted Encumbrances, and have not received any notice of a
                 potential defect or irregularity in their title to any of their
                 assets which, if substantiated, would be reasonably likely to
                 have a Material Adverse Effect.

          (iii)  The Borrower and each Material Subsidiary has good and
                 defensible title to the P&NG Rights described in the most
                 recent Engineering Report provided to the Lenders, subject only
                 to Permitted Title Defects and Permitted Encumbrances.

     (f)  Engineering Reports
          -------------------

          The most recent Engineering Report and other related data provided by
          the Borrower to the Agent in respect of the reserves attributable to
          the P&NG Rights is substantially accurate and fairly reflects the
          interests of the persons specified therein and thereto as of the date
          thereof net of all royalties and other burdens affecting the same.

     (g)  Non-Default
          -----------

          No Default or Event of Default has occurred and is continuing.
<PAGE>

                                      -45-

     (h)  Financial Condition
          -------------------

          (i)  The unaudited consolidated financial statements of the Borrower
               previously delivered to the Agent present fairly, in all material
               respects, the consolidated financial condition of the Borrower as
               at the date thereof and the results of the consolidated
               operations thereof for the year then ending, all in accordance
               with generally accepted accounting principles consistently
               applied.

          (ii) Except as has been disclosed to the Agent by written notice in
               accordance with the provisions of this Agreement, no change in
               the Borrower's consolidated financial condition (as disclosed or
               reflected in the Borrower's most recent consolidated financial
               statements delivered to the Agent) has occurred which would
               reasonably be expected to have a Material Adverse Effect.

     (i)  Absence of Litigation
          ---------------------

          There are no actions, suits or proceedings pending or, to the
          knowledge of the Borrower, threatened against or affecting the
          Borrower or any of its Subsidiaries, including without limitation any
          aboriginal claims against their property or any of their undertakings
          and assets, at law, in equity or before any arbitrator or before or by
          any governmental department, body, commission, board, bureau, agency
          or instrumentality having jurisdiction in the premises in respect of
          which there is a reasonable possibility of a determination adverse to
          the Borrower or any Subsidiary and which, if determined adversely,
          would reasonably be expected to have a Material Adverse Effect.

     (j)  Compliance with Applicable Laws, Court Orders and Material Agreements
          ---------------------------------------------------------------------

          The Borrower and its Subsidiaries and their respective businesses and
          operations are in compliance with all applicable laws (including,
          without limitation, all applicable Environmental Laws), all applicable
          directives, judgments, decrees, injunctions and orders rendered by any
          Governmental Authority or court of competent jurisdiction, its
          constating documents and by-laws, all agreements or instruments to
          which it is a party or by which its property or assets are bound, and

                                      -46-

          force and effect, except to the extent that the failure to have or
          maintain the same in full force and effect would not, when taken in
          the aggregate, reasonably be expected to have a Material Adverse
          Effect.

     (l)  Remittances Up to Date
          ----------------------

          All of the remittances required to be made by the Borrower and its

          arrears, except where and to the extent the failure to remit or delay

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

          The Borrower has no Subsidiaries as at the date hereof.

     (n)  Environmental
          -------------

          (i)  To the best of the knowledge and belief of the Borrower, after

               Assets comply in all material respects and the businesses,
               activities and operations of same and the use of the Neutrino
               Assets and the processes and undertakings performed thereon
               comply in all material respects with all Environmental Laws,
               Environmental Permits and Environmental Orders; further, the
               Borrower does not know, and has no reasonable grounds to know, of
               any facts which result in or constitute or are likely to give
               rise to non-compliance with any Environmental Laws, Environmental
               Permits or Environmental Orders which facts or non-compliance do
               or could reasonably be expected to have a Material Adverse
               Effect.

          (ii) To the best of the knowledge and belief of the Borrower, after
               due inquiry, the Borrower and its Subsidiaries have obtained all
               Environmental Permits which are required of any of them to the

               their businesses, activities, operations, processes and
               undertakings; all such Environmental Permits are valid and in
               full force and effect, and no material violations thereof have
               been experienced, noted or recorded which are continuing and no
               proceeding is pending and, to the best of the knowledge and
               belief of the Borrower, after due inquiry, no proceedings have
               been or are being taken by any Governmental Authority to remove
               or invalidate any of the Environmental Permits, the removal or
               invalidation of which would reasonably be expected to have a
               Material Adverse Effect.

                  the Neutrino Assets and the businesses, activities and
                  operations of the Borrower and its Subsidiaries have not and

                  material respects with all Environmental Laws, Environmental
                  Permits and Environmental Orders, except to the extent that
                  such non-compliance would not have or would not reasonably be
                  expected to have a Material Adverse Effect.

          (iv)    To the best of the knowledge and belief of the Borrower, after
                  due inquiry, all contaminants and Hazardous Materials owned or

                  Environmental Laws, Environmental Permits and Environmental
                  Orders except to the extent that such non-compliance would not

                  Adverse Effect.

                  Environmental Laws, Environmental Permits or Environmental
                  Orders, and has no knowledge after due inquiry, of any facts
                  which could give rise to any notice, of non-compliance with
                  any Environmental Laws, Environmental Permits and
                  Environmental Orders which facts or non-compliance do or could
                  reasonably be expected to have a Material Adverse Effect or
                  any notice that the Borrower or any of its Subsidiaries is a
                  potentially responsible party for a federal, provincial,
                  regional, municipal or local clean-up or corrective action in
                  connection with the Neutrino Assets which could reasonably be
                  expected to have a Material Adverse Effect.

          (vi)    To the best of the knowledge and belief of the Borrower, there

                  activities or operations of the Borrower or its Material
                  Subsidiaries.

                  offence for non-compliance with any Environmental Laws,
                  Environmental Permits or Environmental Orders or been fined or
                  otherwise sentenced or settled such prosecution short of
                  conviction.

                  the extent that such non-compliance would not have or would
                  not reasonably be expected to have a Material Adverse Effect.

          (ix)    The Borrower and its Material Subsidiaries have in effect a
                  management structure and policies and procedures that will
                  permit the Borrower to effectively manage environmental risk

          provision for, and all required instalment payments have been made in
          respect of, Taxes payable for the current period for which returns are
          not yet required to be filed; there are no agreements, waivers or

     pursuant to this Section and the Borrower shall, as soon as possible after
     the notice period set forth in the request by the Agent (but in any event
     within 20 days after the expiration of such 20 day notice period):

     (a)  execute and deliver, and cause to be executed and delivered, all such
          mortgages, debentures, security agreements, trust deeds, guarantees,
          agreements and other instruments (each in form and substance
          satisfactory to the Agent) as may be necessary to create the aforesaid
          fixed mortgages and charges and shall do all other things as may be
          necessary to grant in favour of the Agent the aforesaid fixed
          mortgages and charges;
<PAGE>

                                      -62-

     (b)  provide and cause its Material Subsidiaries required pursuant to
          Section 10.1(2) to provide to the Agent certified copies of all
          corporate resolutions and other authorizations necessary for the
          Borrower and such Subsidiaries to grant to the Agent the fixed
          mortgages and charges as aforesaid, together with such opinions of
          legal counsel to the Borrower and such Subsidiaries as the Agent may
          reasonably require with respect to the due authorization, execution,
          delivery and enforceability of the above agreements and instruments
          and as to the registration or recording of such agreements and
          instruments;

     (c)  assist and cause such Subsidiaries to assist the Agent in the
          registration or recording of such agreements and instruments in such
          public registry offices as the Agent, acting reasonably, deems
          necessary to give full force and effect to the provisions of this
          Section; and

     (d)  pay all reasonable costs and expenses incurred by the Agent and the
          Lenders in connection with the preparation, execution and registration
          of all agreements and instruments, including any amendments to the
          Security, made in connection with this Section.

10.4 Continuing Security

     Each item or part of the Security shall for all purposes be treated as a
separate and continuing collateral security and shall be deemed to have been
given in addition to and not in place of any other item or part of the Security
or any other security now held or hereafter acquired by the Agent or the
Lenders.  No item or part of the Security shall be merged or be deemed to have
been merged in or by this Agreement or any documents, instruments or
acknowledgements delivered hereunder, or any simple contract debt or any
judgment, and any realization of or steps taken under or pursuant to any
security, instrument or agreement shall be independent of and not create a
merger with any other right available to the Agent or the Lenders under any
security, instruments or agreements held by it or at law or in equity.

10.5 Dealing with Security

     The Agent, with the consent of all the Lenders, may grant extensions of
time or other indulgences, take and give up security (including, without
limitation, the Security or any part or parts thereof), accept compositions,
grant releases and discharges.  The Agent may otherwise deal with the Borrower,
its Subsidiaries and other parties and with security (including without
limitation, the Security and each part thereof) as the Agent and the Lenders may
see fit, and may, subject to Section 7.4, apply all amounts received from the
Borrower or others or from security (including without limitation, the Security
or any part thereof) upon such part of the liabilities of the Borrower hereunder
or under any of the Security as the Agent may think best, without prejudice to
or in any
<PAGE>

                                      -63-

way limiting the liability of the Borrower under this Agreement or under any of
the Security or any other collateral security.

10.6 Effectiveness

     The Security and the security created by any other Document constituted or
required to be created shall be effective, and the undertakings as to the
Security herein or in any other Document shall be continuing, whether any Loans
are then outstanding or any amounts thereby secured or any part thereof shall be
owing before or after, or at the same time as, the creation of such Security
Interests or before or after or upon the date of execution of any amendments to
this Agreement.

10.7 Saskatchewan Legislation

     The Land Contracts (Actions) Act (Saskatchewan) shall have no application
to any action, as defined in the said Land Contracts (Actions) Act, with respect
to this Agreement and the other Documents; and The Limitation of Civil Rights
Act (Saskatchewan) shall have no application to this Agreement and the other
Documents, any Security Interest for the payment of money made, given or created
by this Agreement or the other Documents, any agreement or instrument renewing
or extending this Agreement or the other Documents or any such Security
Interest, or the rights, powers or remedies of the Agent or any of the Lenders
under this Agreement, the other Documents or any such Security Interest.  The
Borrower agrees that the provisions of both The Land Contracts (Actions) Act and
The Limitation of Civil Rights Act are hereby waived and covenants that each
Subsidiary providing security to the Lenders (if any) shall waive such
provisions in writing to the satisfaction of the Agent.

10.8 Release and Discharge of Security

     The Borrower and the Material Subsidiaries shall not be discharged from the
Security or any part thereof, other than to the extent such Security applies to
a Permitted Disposition, except by a written release and discharge signed by the
Agent with the prior consent of the Lenders.  If all of the Obligations,
Financial Instrument Obligations and other obligations of the Borrower to the
Agent and the Lenders have been repaid, paid, satisfied and discharged, as the
case may be, in full, the Credit Facility has been fully cancelled and the
Lenders then have no credit facilities in favour of or obligation to provide
credit to the Borrower, then the Security shall be released and discharged by
the Agent and the Lenders.  The Agent, at the cost and expense of the Borrower,
shall from time to time do, execute and deliver, or cause to be done, executed
and delivered, all such agreements, instruments, certificates, financing
statements, notices and other documents and all acts, matters and things as may
be reasonably requested by the Borrower to give effect to, establish, evidence
or record the foregoing release and discharge.

                      EVENTS OF DEFAULT AND ACCELERATION

11.1 Events of Default

     The occurrence of any one or more of the following events (each such event

          elsewhere in this Section 11.1) and, after notice has been given by

          prove to have been incorrect or misleading in any material respect on
          and as of the date made;

     (g)  if a decree or order of a court of competent jurisdiction is entered
          adjudging the Borrower or a Material Subsidiary a bankrupt or
          insolvent or approving as properly filed a petition seeking the
          winding-up of the Borrower or a Material Subsidiary under the

          unstayed and in effect for a period of 30 days;

     (h)  if the Borrower or a Material Subsidiary makes any assignment in

          makes any proposal under the Bankruptcy and Insolvency Act (Canada) or
          any comparable law, seeks relief under the Companies' Creditors

          similar law affecting creditors' rights or consents to, or acquiesces
          in, the filing of such a petition;

     (i)  if a secured party, holder of a Security Interest or other

          of the Borrower or any Material Subsidiary which is material to the
          Borrower and its Subsidiaries taken as a whole or if a distress or

<PAGE>

                                      -66-

     (k)  except for Permitted Encumbrances, if any of the Security Interests
          created by the Security, to the extent such Security Interests have
          been perfected by registration or otherwise, shall cease to be a valid
          first priority Security Interest as against third parties;

     (l)  if any Document or any material provision thereof shall at any time
          for any reason cease to be in full force and effect, be declared to be
          void or voidable or shall be repudiated, or the validity or
          enforceability thereof shall at any time be contested by the Borrower
          or a Material Subsidiary, or the Borrower or a Material Subsidiary
          shall deny that it has any or any further liability or obligation
          thereunder, or at any time it shall be unlawful or impossible for any
          of them to perform any of the Obligations;

     (m)  except in compliance herewith, if the Borrower shall dissolve, be

          otherwise dispose of all or substantially of its assets, or shall
          threaten or take any step, proceeding or other action in furtherance
          of any of the foregoing; or

     (n)  if there is a Change of Control.

11.2 Acceleration

     If any Event of Default shall occur,

     (a)  the entire principal amount of all Loans then outstanding and all
          accrued and unpaid interest thereon,

     (b)  an amount equal to the maximum amount available to be drawn under all
          unexpired LCs,

     (c)  an amount equal to the maximum amount guaranteed under all unexpired
          LGs, and

     (d)  all other Obligations outstanding hereunder,

shall, at the option of the Agent, and in accordance with Section 14.11, or upon
the request of a Majority of the Lenders, become immediately due and payable
upon written notice to that effect from the Agent to the Borrower, all without
any other notice and without presentment, protest, demand, notice of dishonour
or any other demand whatsoever (all of which are hereby expressly waived by the
Borrower).  In such event and if the Borrower does not immediately pay all such
amounts upon receipt of such notice, either the Lenders or the Agent on their
behalf may, in their discretion, exercise any right or recourse and/or proceed
by any action, suit, remedy or proceeding against the Borrower authorized or
permitted by law for the recovery of all the indebtedness and liabilities of the
Borrower to the Lenders and proceed to exercise any and all rights hereunder and
under the other
<PAGE>

                                      -67-

Documents and no such remedy for the enforcement of the rights of the Lenders
shall be exclusive of or dependent on any other remedy but any one or more of
such remedies may from time to time be exercised independently or in
combination.

11.3 Conversion on Default

     Upon the occurrence of an Event of Default, the Agent on behalf of the
Lenders may convert, at the Equivalent Amount, if applicable, an Alternate Base
Rate Loan at any time, to a Canadian Prime Rate Loan.  Interest shall accrue on
each such Canadian Prime Rate Loan at the rates provided in Section 5.1, such
interest to be calculated daily and payable on demand.

11.4 Remedies Cumulative and Waivers

     For greater certainty, it is expressly understood and agreed that the
rights and remedies of the Lenders and the Agent hereunder or under any other
Document are cumulative and are in addition to and not in substitution for any
rights or remedies provided by law or by equity; and any single or partial
exercise by the Lenders or the Agent of any right or remedy for a default or
breach of any term, covenant, condition or agreement contained in this Agreement
or other Document shall not be deemed to be a waiver of or to alter, affect or
prejudice any other right or remedy or other rights or remedies to which any one
or more of the Lenders or the Agent may be lawfully entitled for such default or
breach.  Any waiver by, as applicable, the Majority of the Lenders, the Lenders
or the Agent of the strict observance, performance or compliance with any term,
covenant, condition or other matter contained herein or in the other Documents
and any indulgence granted, either expressly or by course of conduct, by, as
applicable, the Majority of the Lenders, the Lenders or the Agent shall be
effective only in the specific instance and for the purpose for which it was
given and shall be deemed not to be a waiver of any rights and remedies of such
Person or Persons under this Agreement or any other Document as a result of any
other default or breach hereunder or thereunder.

11.5 Termination of Lenders' Obligations

     The occurrence of a Default which is continuing shall relieve the Lenders
of all obligations to provide any further Drawdowns or Conversions hereunder;
provided that the foregoing shall not prevent the Lenders or the Agent from
disbursing money or effecting any Conversion which, by the terms hereof, they
are entitled to effect, or any Conversion requested by the Borrower and
acceptable to the Lenders and the Agent.

                            CHANGE OF CIRCUMSTANCES

12.1 Change in Law

     If the adoption of any applicable law, regulation, treaty or official
directive (whether or not having the force of law) or any change therein or in
the interpretation or application thereof by any court or by any Governmental
Authority or any other entity charged with the interpretation or administration
thereof or compliance by the Lender with any request or direction (whether or
not having the force of law) of any such authority or entity, hereafter:

     (a)  subjects any Lender to, or causes the withdrawal or termination of any
          previously granted exemption with respect to, any tax or changes the
          basis of taxation, or increases any existing tax, on payments of
          principal, interest, fees or other amounts payable by the Borrower to
          such Lender under this Agreement (except for taxes based on the
          capital or overall income of such Lender);

     (b)  imposes, modifies or deems applicable any reserve, liquidity, cash
          margin, capital, deposit insurance, special deposit or similar
          requirements against assets held by, or deposits in or for the account
          of or loans by or to or any other acquisition of funds by, or drafts
          accepted by, an office of any Lender;

     (c)  imposes on any Lender or expects there to be maintained by any Lender
          any capital adequacy or additional capital requirements in respect of
          any Loans or the Credit Facility hereunder or any other condition with
          respect to this Agreement; or

     (d)  imposes on any Lender any other conditions or requirements relevant to
          the Documents or the Credit Facility,

and the result of any of the foregoing, in the sole determination of such Lender
acting reasonably and in good faith, shall be to increase the cost to, or reduce
the amount of principal, interest, fees or other amount received or receivable
by such Lender hereunder or its effective return hereunder or on its capital in
respect of the Credit Facility or the making, maintaining or funding a Loan
under the Credit Facility or cause such Lender to make any payment or forego any
interest, fees or other return hereunder, such Lender shall determine that
amount of money which shall compensate such Lender for such increase in cost,
payments to be made or reduction in income or return or interest foregone
(herein referred to as "Additional Compensation").  Upon a Lender having
determined that it is entitled to Additional Compensation in accordance with the
provisions of this Section, such Lender shall promptly so notify the Borrower
and the Agent and shall provide the Borrower and the Agent with a photocopy of
the relevant law, rule, guideline, regulation, treaty or official directive (or,
if it is impracticable to provide a photocopy, a written summary of the same)
and a certificate of a duly authorized officer of such Lender setting forth the
Additional Compensation and the basis of calculation therefor, which shall be
conclusive evidence of such Additional Compensation in the
<PAGE>

                                      -69-

absence of manifest error. The Borrower shall pay to such Lender within 10
Banking Days of the giving of such notice such Lender's Additional Compensation
calculated from the later of (i) the effective date of the relevant introduction
or change and (ii) 3 months prior to the date of such notification. Each of the
Lenders shall be entitled to be paid such Additional Compensation from time to
time to the extent that the provisions of this Section are then applicable
notwithstanding that any Lender has previously been paid any Additional
Compensation. The Lenders shall endeavour to limit the incidence of any such
Additional Compensation, including (without limitation) seeking recovery for the
account of the Borrower by appealing any assessment (providing that the same
shall not be adverse to the interests of the Lenders, in their sole discretion)
at the expense of the Borrower upon the Borrower's request.


12.2 Prepayment of Portion

     In addition to the other rights and options of the Borrower hereunder and
notwithstanding any contrary provisions hereof, if a Lender gives the notice
provided for in Section 12.2 with respect to any Loan (an "Affected Loan"), the
Borrower may, upon 3 Banking Days notice to that effect given to such Lender and
the Agent (which notice shall be irrevocable), prepay in full without penalty
such Lender's Rateable Portion of the Affected Loan outstanding together with
accrued and unpaid interest on the principal amount so prepaid up to the date of
such prepayment, such Additional Compensation as may be applicable to the date
of such payment and all costs, losses and expenses incurred by such Lender by
reason of the liquidation or re-deployment of deposits or other funds or for any
other reason whatsoever resulting from the repayment of such Affected Loan or
any part thereof on other than the last day of the applicable Interest Period,
and upon such payment being made that Lender's obligations to make such Affected
Loans to the Borrower under this Agreement shall terminate.

12.3 Illegality

     If the adoption of any applicable law, regulation, treaty or official
directive (whether or not having the force of law) or any change therein or in
the interpretation or application thereof by any court or by any Governmental
Authority or any other entity charged with the interpretation or administration
thereof or compliance by such Lender with any request or direction (whether or
not having the force of law) of any such authority or entity, now or hereafter
makes it unlawful or impossible for such Lender to make, fund or maintain the
Credit Facility or a Loan under the Credit Facility or to give effect to its
obligations in respect of such a Loan, such Lender may, by written notice
thereof to the Borrower declare its obligations under this Agreement in respect
of such Loan to be terminated whereupon the same shall forthwith terminate, and
the Borrower shall, within the time required by such law (or at the end of such
longer period as such Lender at its discretion has agreed), either effect a
Conversion of such Loan in accordance with the provisions hereof (if such
Conversion would resolve the unlawfulness or impossibility) or prepay the
principal of such Loan together with accrued interest.  If any such change shall
only affect a portion of a Lender's obligations under this Agreement which is,
in the sole opinion of such Lender, severable from the
<PAGE>

                                      -70-

remainder of this Agreement so that the remainder of this Agreement may be
continued in full force and effect without otherwise affecting any of the other
obligations of such Lender or the Borrower hereunder, such Lender shall only
declare its obligations under that portion so terminated.


                                  ARTICLE 13
                      COSTS, EXPENSES AND INDEMNIFICATION

13.1 Costs and Expenses

     The Borrower shall pay promptly upon notice from the Agent all reasonable
costs and expenses of the Lenders and the Agent in connection with the Documents
and the establishment of the Credit Facility, including, without limitation, in
connection with preparation, printing, execution and delivery of this Agreement
and the other Documents whether or not any Drawdown has been made hereunder, and
also including, without limitation, the reasonable fees and out-of-pocket
expenses of Lenders' Counsel with respect thereto and with respect to advising
the Agent and the Lenders as to their rights and responsibilities under this
Agreement and the other Documents. Except for ordinary expenses of the Lenders
and the Agent relating to the day-to-day administration of this Agreement, the
Borrower further agrees to pay within 30 days of demand by the Agent all
reasonable costs and expenses in connection with the preparation or review of
waivers, consents and amendments pertaining to this Agreement and in connection
with the establishment of the validity and enforceability of this Agreement and
the preservation or enforcement of rights of the Lenders and the Agent under
this Agreement and other Documents, including, without limitation, all
reasonable costs and expenses sustained by the Lenders and the Agent as a result
of any failure by the Borrower to perform or observe any of its obligations
hereunder, together with interest thereon from and after such 30th day if such
payment is not made by such time.

13.2 General Indemnity

     In addition to any liability of the Borrower to the Agent and the Lenders
under any other provision hereof, the Borrower shall indemnify each Lender and
the Agent and their respective Affiliates, directors, officers, agents and
employees (collectively in this Section the 'Indemnified Parties") and hold each
Indemnified Party harmless against any loss, cost, expense, damage, claim or
liability and reasonable out-of-pocket expenses and reasonable legal fees on a
solicitor and his own client basis) as a result of or in connection with:

     (a)  all claims, suits, debts, damages, costs, losses, liabilities,
          penalties, obligations, judgments, charges, expenses and disbursements
          arising in connection with any action, suit, or proceeding (whether or
          not an Indemnified Party is a party or subject thereto) relating to
          the Credit Facilities or the Documents;
<PAGE>

                                      -71-

     (b)  any cost or expense incurred by reason of the liquidation or re-
          deployment in whole or in part of deposits or other funds required by
          any Lender to fund or maintain any Loan as a result of the Borrower's
          failure to complete a Drawdown or to make any payment, repayment or
          prepayment on the date required hereunder or specified by it in any
          notice given hereunder;

     (c)  the Borrower's failure to pay any other amount, including without
          limitation any interest or fee, due hereunder on its due date after
          the expiration of any applicable grace or notice periods (subject,
          however, to the interest obligations hereunder for overdue amounts);

     (d)  the Borrower's failure to give any notice required to be given by it
          to the Lenders hereunder;

     (e)  the inaccuracy of the Borrower's representations and warranties
          contained in Section 8.1;

     (f)  the failure of the Borrower to make any other payment due hereunder;

     (g)  any failure of the Borrower or any Material Subsidiary to observe or
          fulfil any other Obligation not specifically referred to above; or

     (h)  any Default or Event of Default.

13.3 Environmental Indemnity

     The Borrower shall indemnify and hold harmless the Agent and the Lenders
including a receiver, receiver-manager or similar person appointed under
applicable law and its respective Affiliates, officers, directors, employees and
agents (collectively, the "Indemnified Parties") forthwith on demand by the
Agent from and against any and all claims, suits, actions, debts, damages,
costs, losses, liabilities, penalties, obligations, judgments, charges, expenses
and disbursements (including without limitation, all reasonable legal fees and
disbursements on a solicitor and his own client basis) of any nature whatsoever,
suffered or incurred by the Indemnified Parties or any of them in connection
with the Credit Facility, whether as beneficiaries under the Documents, as
successors in interest of the Borrower or any of its Subsidiaries, or voluntary
transfer in lieu of foreclosure, or otherwise howsoever, with respect to any
Environmental Claims relating to the property of the Borrower or any of its
Subsidiaries arising under any Environmental Laws as a result of the past,
present or future operations of the Borrower or any of its Subsidiaries (or any
predecessor in interest to the Borrower or any of its Subsidiaries) relating to
the property of the Borrower or of its Subsidiaries, or the past, present or
future condition of any part of the property of the Borrower or its Subsidiaries
owned, operated or leased by the Borrower or by any of its Subsidiaries (or any
such predecessor in interest), including any liabilities arising after an
acceleration of all Loans as a result of any indemnity covering Environmental
Claims given to any
<PAGE>

                                      -72-

person by the Lenders or a receiver, receiver-manager or similar person
appointed hereunder or under applicable law (collectively, the "Indemnified
Third Party"); but excluding any Environmental Claims or liabilities relating
thereto to the extent that such Environmental Claims or liabilities arise by
reason of the gross negligence or wilful misconduct of the Indemnified Party or
the Indemnified Third Party claiming indemnity hereunder. The provisions of this
Section shall survive the repayment of the Obligations.

13.4 Judgment Currency

     If, for the purposes of obtaining or enforcing judgment in any court in any
jurisdiction, it becomes necessary to convert into the currency of the country
giving such judgment (the "Judgment Currency") an amount due hereunder in
different currency (the "Agreed Currency"), then the date on which the rate of
exchange for conversion is selected by that court is referred to herein as the
"Exchange Date".  If there is a change in the rate of exchange between the
Judgment Currency and the Agreed Currency between the Exchange Date and the
actual receipt of any Lender of the amount due hereunder or under such judgment,
the Borrower will, notwithstanding such judgment, pay to such Lender all such
additional amounts as may be necessary to ensure that the amount received by
such Lender in the Judgment Currency, when converted at the rate of exchange
prevailing on the date of receipt, will produce the amount due in the Agreed
Currency.  The Borrower's liability hereunder constitutes a separate and
independent liability which will not merge with any judgment or any partial
payment or enforcement of payment of sums due under the Documents and such
liability, together with interest thereon, shall be added to the amount payable
hereunder.  The term "rate of exchange", as used in this paragraph, includes any
premiums or costs payable in connection with the currency conversion then being
effected.


                                  ARTICLE 14
              THE AGENT AND ADMINISTRATION OF THE CREDIT FACILITY

14.1 Authorization and Action

     (1)  Each Lender hereby irrevocably appoints and authorizes the Agent to be
its agent in its name and on its behalf to exercise such rights or powers
granted to the Agent or the Lenders under this Agreement to the extent
specifically provided herein and on the terms hereof, together with such powers
as are reasonably incidental thereto and the Agent hereby accepts such
appointment and authorization. As to any matters not expressly provided for by
this Agreement, the Agent shall not be required to exercise any discretion or
take any action, but, subject to Section 15.10, 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 Majority of the Lenders and such
instructions shall be binding upon all Lenders; provided, however, that the
Agent shall not be required to take any action which exposes the Agent to
liability in such capacity or which could result in the Agent's incurring any
costs and expenses, without provision being made for indemnity of the Agent by
the Lenders against
<PAGE>

                                      -73-

any loss, liability, cost or expense incurred, or to be incurred or which is
contrary to this Agreement or applicable law.

     (2)  The Lenders agree that all decisions as to actions to be or not to be
taken, as to consents or waivers to be given or not to be given, as to
determinations to be made and otherwise in connection with this Agreement and
the Documents, shall be made upon the decision of the Majority of the Lenders
except in respect of a decision or determination where it is specifically
provided in this Agreement that "all of the Lenders" or "the Lenders" or words
to similar effect, or the Agent alone, is to be responsible for same.  Each of
the Lenders shall be bound by and agrees to abide by and adopt all decisions
made as aforesaid and covenants in all communications with the Borrower to act
in concert and to join in the action, consent, waiver, determination or other
matter decided as aforesaid.

14.2 Procedure for Making Loans

     (1)  The Agent shall make Loans available to the Borrower as required
hereunder by debiting the account of the Agent to which the Lenders' Rateable
Portions of such Loans have been credited in accordance with Section 2.10 (or
causing such account to be debited) and, in the absence of other arrangements
agreed to by the Agent and the Borrower in writing, by crediting the account of
the Borrower or, at the expense of the Borrower, transferring (or causing to be
transferred) like funds in accordance with the instructions of the Borrower as
set forth in the Drawdown Notice or Conversion Notice, as the case may be, in
respect of each Loan; provided that the obligation of the Agent hereunder to
effect such a transfer shall be limited to taking such steps as are commercially
reasonable to implement such instructions, which steps once taken shall
constitute conclusive and binding evidence that such funds were advanced
hereunder in accordance with the provisions relating thereto and the Agent shall
not be liable for any damages, claims or costs which may be suffered by the
Borrower and occasioned by the failure of such Loan to reach the designated
destination.

     (2)  Unless the Agent has been notified by a Lender at least one Banking
Day prior to the Drawdown Date or Conversion Date, as the case may be, requested
by the Borrower that such Lender will not make available to the Agent its
Rateable Portion of such Loan, the Agent may assume that such Lender has made or
will make such portion of the Loan available to the Agent on the Drawdown Date
or Conversion Date, as the case may be, in accordance with the provisions hereof
and the Agent may, but shall be in no way obligated to, in reliance upon such
assumption, make available to the Borrower on such date a corresponding amount.
If and to the extent such Lender shall not have so made its Rateable Portion of
a Loan available to the Agent, such Lender agrees to pay to the Agent forthwith
on demand such Lender's Rateable Portion of the Loan and all reasonable costs
and expenses incurred by the Agent in connection therewith together with
interest thereon (at the rate payable hereunder by the Borrower in respect of
such Loan for each day from the date such amount is made available to the
Borrower until the date such amount is paid to the Agent; provided, however,
that notwithstanding such obligation if such Lender fails to so pay, the
Borrower covenants and agrees that without prejudice to any rights the Borrower
may have against such Lender, it shall repay such amount to the Agent forthwith
after demand therefor by the Agent. The amount payable
<PAGE>

                                      -74-

to the Agent pursuant hereto shall be set forth in a certificate delivered by
the Agent to such Lender and the Borrower (which certificate shall contain
reasonable details of how the amount payable is calculated) and shall be prima
facie evidence thereof, in the absence of manifest error. If such Lender makes
the payment to the Agent required herein, the amount so paid shall constitute
such Lender's Rateable Portion of the Loan for purposes of this Agreement. The
failure of any Lender to make its Rateable Portion of any Loan shall not relieve
any other Lender of its obligation, if any, hereunder to make its Rateable
Portion of such Loan on the Drawdown Date or Conversion Date, as the case may
be, but no Lender shall be responsible for the failure of any other Lender to
make the Rateable Portion of any Loan to be made by such other Lender on the
date of any Drawdown or Conversion, as the case may be.

14.3 Remittance of Payments

     Forthwith after receipt of any repayment pursuant hereto or payment of
interest or fees pursuant to Article 5 or payment pursuant to Article 7, the
Agent shall remit to each Lender its Rateable Portion of such payment; provided
that, if the Agent, on the assumption that it will receive on any particular
date a payment of principal, interest or fees hereunder, remits to a Lender its
Rateable Portion of such payment and the Borrower fails to make such payment,
each of the Lenders on receipt of such remittance from the Agent agrees to repay
to the Agent forthwith on demand an amount equal to the remittance together with
all reasonable costs and expenses incurred by the Agent in connection therewith
and interest thereon at the rate and calculated in the manner applicable to the
Loan in respect of which such payment is made for each day from the date such
amount is remitted to the Lenders without prejudice to any right such Lender may
have against the Borrower. The exact amount of the repayment required to be made
by the Lenders pursuant hereto shall be as set forth in a certificate delivered
by the Agent to each Lender, which certificate shall be conclusive and binding
for all purposes in the absence of manifest error.

14.4 Redistribution of Payment

     Each Lender agrees that:

     (a)  if it exercises any security against or right of counter-claim, set
          off or banker's Security Interest or similar right with respect to the
          property of the Borrower or if under any applicable bankruptcy,
          insolvency or other similar law it receives a secured claim and
          collateral for which it is, or is entitled to exercise any set-off
          against, a debt owed by it to the Borrower, the Lender shall apportion
          the amount thereof proportionately between:

          (i)  such Lender's Rateable Portion of all outstanding Obligations
               which amounts shall be applied in accordance with Section
               14.4(b); and

          (ii) amounts otherwise owed to such Lender by the Borrower,
<PAGE>

                                      -75-

     provided that (A) any cash collateral account held by such Lender as
     collateral for a letter of credit issued or accepted by such Lender on
     behalf of the Borrower may be applied by such Lender to such amounts owed
     by the Borrower to such Lender pursuant to such letter of credit without
     apportionment and (B) these provisions do not apply to a right or claim
     which arises or exists in respect of a loan or other debt in respect of
     which the relevant Lender holds a Security Interest excluded from the
     application of Section 9.2(b) and

     (b)  if, in the aforementioned circumstances, the Lender, through the
          exercise of a right, or the receipt of a secured claim described in
          Section 14.4(a) above or otherwise, receives payment of a proportion
          of the aggregate amount of Obligations due to it hereunder which is
          greater than the proportion received by any other Lender in respect of
          the aggregate Obligations due to such Lender (having regard to the
          respective Rateable Portions of the Lenders), the Lender receiving
          such proportionately greater payment shall purchase, on a non-recourse
          basis at par, and make payment for a participation (which shall be
          deemed to have been done simultaneously with receipt of such payment)
          in the outstanding Loans of the other Lender or Lenders so that their
          respective receipts shall be pro rata to their respective Rateable
          Portions; provided, however, that if all or part of such
          proportionately greater payment received by such purchasing Lender
          shall be recovered by or on behalf of the Borrower or any trustee,
          liquidator, receiver or receiver-manager or person with analogous
          powers from the purchasing Lender, such purchase shall be rescinded
          and the purchase price paid for such participation shall be returned
          to the extent of such recovery, but without interest unless the
          purchasing Lender is required to pay interest on such amount, in which
          case each selling Lender shall reimburse the purchasing Lender pro
          rata in relation to the amounts received by it.  Such Lender shall
          exercise its rights in respect of such secured claim in a manner
          consistent with the rights of the Lenders entitled under this Section
          to share in the benefits of any recovery on such secured claims; and

     (c)  if the Lender does, or is required to do, any act or thing permitted
          by Section 14.4(a) or (b) above, it shall promptly provide full
          particulars thereof to the Agent.


14.5 Duties and Obligations

     Neither the Agent nor any of its directors, officers, agents or employees
(and, for purposes hereof, the Agent shall be deemed to be contracting as agent
and trustee for and on behalf of such persons) shall be liable to the Lenders
for any action taken or omitted to be taken by it or them under or in connection
with this Agreement except for its or their own gross negligence or wilful
misconduct.  Without limiting the generality of the foregoing, the Agent:
<PAGE>

                                      -76-

     (a)  may assume that there has been no assignment or transfer by any means
          by the Lenders of their rights hereunder, unless and until the Agent
          receives written notice of the assignment thereof from such Lender and
          the Agent receives from the assignee an executed assignment agreement
          providing, inter alia, that such assignee is bound hereby as it would
          have been if it had been an original Lender party hereto;

     (b)  may consult with legal counsel (including receiving the opinions of
          Borrower's counsel required hereunder), 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 or such counsel, accountants or experts;

     (c)  shall incur no liability under or in respect of this Agreement by
          acting upon any notice, consent, certificate or other instrument or
          writing (which may be by telegram, cable, telecopier or telex)
          believed by it to be genuine and signed or sent by the proper party or
          parties or by acting upon any representation or warranty of the
          Borrower made or deemed to be made hereunder;

     (d)  may assume that no Event of Default has occurred and is continuing
          unless it has actual knowledge to the contrary;

     (e)  may rely as to any matters of fact which might reasonably be expected
          to be within the knowledge of any person upon a certificate signed by
          or on behalf of such person;

     (f)  shall not be bound to disclose to any other person any information
          relating to the Borrower, any of its Subsidiaries or any other person
          if such disclosure would or might in its or their opinion constitute a
          breach of any applicable law, be in default of the provisions hereof
          or be otherwise actionable at the suit of any other person; and

     (g)  may refrain from exercising any right, power or discretion vested in
          it which would or might in its or their reasonable opinion be contrary
          to any applicable law or any directive or otherwise render it or them
          liable to any person, and may do anything which is in its or their
          reasonable opinion necessary to comply with such applicable law.

     Further, the Agent (i) does not make any warranty or representation to any
Lender nor shall it be responsible to any Lender for the accuracy or
completeness of the representations and warranties of the Borrower herein or the
data made available to any of the Lenders in connection with the negotiation of
this Agreement, or for any statements, warranties or representations (whether
written or oral) made in or in connection with this Agreement; (ii) shall not
have any duty to ascertain or to enquire as to the performance or observance of
any of the terms, covenants or conditions of this Agreement on the part of the
Borrower or to inspect the property (including the
<PAGE>

                                      -77-

books and records) of the Borrower or any of its Subsidiaries; and (iii) shall
not be responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement or any
instrument or document furnished pursuant hereto.

14.6 Prompt Notice to the Lenders

     Notwithstanding any other provision herein, the Agent agrees to provide to
the Lenders, with copies where appropriate, all information, notices and reports
required to be given to the Agent by the Borrower, promptly upon receipt of
same, excepting therefrom information and notices relating solely to the role of
Agent hereunder.

14.7 Agent's and Lender's Authorities

     With respect to its Commitment and the Drawdowns, Conversions and Loans
made by it as a Lender, the Agent shall have the same rights and powers under
this Agreement as any other Lender and may exercise the same as though it were
not the Agent.  Subject to the express provisions hereof relating to the rights
and obligations of the Agent and the Lenders in such capacities, the Agent and
each Lender may accept deposits from, lend money to, and generally engage in any
kind of business with the Borrower and its Subsidiaries or any corporation or
other entity owned or controlled by any of them and any person which may do
business with any of them without any duties to account therefor to the Agent or
the other Lenders and, in the case of the Agent, all as if it was not the Agent
hereunder.

14.8 Lender Credit Decision

     It is understood and agreed by each Lender that it has itself been, and
will continue to be, solely responsible for making its own independent appraisal
of and investigations into the financial condition, creditworthiness, condition,
affairs, status and nature of the Borrower and its Subsidiaries. Each Lender
represents to the Agent that it is engaged in the business of making and
evaluating the risks associated with commercial revolving or term loans, or
both, to corporations similar to the Borrower, that it can bear the economic
risks related to the transaction contemplated hereby, that it has had access to
all information deemed necessary by it in making such decision (provided that
this representation shall not impair its rights against the Borrower) and that
it is entering into this Agreement in the ordinary course of its commercial
lending business.  Accordingly, each Lender confirms with the Agent that it has
not relied, and will not hereafter rely, on the Agent (i) to check or enquire on
its behalf into the adequacy, accuracy or completeness of any information
provided by the Borrower or any other person under or in connection with this
Agreement or the transactions herein contemplated (whether or not such
information has been or is hereafter distributed to such Lender by the Agent),
or (ii) to assess or keep under review on its behalf the financial condition,
creditworthiness, condition, affairs, status or nature of the Borrower or any of
its Subsidiaries.  Each Lender acknowledges that a copy of this Agreement has
been made available to it for review and each Lender acknowledges that it is
satisfied with the form and substance of this Agreement.  Each Lender hereby
covenants and agrees that, subject to Section 14.4, it will not make any
arrangements
<PAGE>

                                      -78-

with the Borrower for the satisfaction of any Loans or other Obligations without
the consent of all the other Lenders.

14.9  Indemnification of Agent

      The Lenders hereby agree to indemnify the Agent (to the extent not
reimbursed by the Borrower), on a pro rata basis in accordance with their
respective Commitments as a proportion of the aggregate of all outstanding
Commitments, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may be imposed on, incurred by, or
asserted against the Agent in any way relating to or arising out of this
Agreement or any action taken or omitted by the Agent under or in respect of
this Agreement in its capacity as Agent; provided that no Lender shall be liable
for any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs expenses or disbursements resulting from the
Agent's gross negligence or wilful misconduct.  If the Borrower subsequently
repays all or a portion of such amounts to the Agent, the Agent shall reimburse
the Lenders their pro rata shares (according to the amounts paid by them in
respect thereof) of the amounts received from the Borrower.  Without limiting
the generality of the foregoing, each Lender agrees to reimburse the Agent
promptly upon demand for its portion (determined as above) of any out-of-pocket
expenses (including counsel fees) incurred by the Agent in connection with the
preservation of any rights of the Agent or the Lenders under, or the enforcement
of, or legal advice in respect of rights or responsibilities under, this
Agreement, to the extent that the Agent is not reimbursed for such expenses by
the Borrower.

14.10 Successor Agent

      (1) The Agent may, as hereinafter provided, resign at any time by giving
45 days' prior written notice thereof to the Lenders and the Borrower. Upon any
such resignation, the Lenders shall have the right to appoint another Lender as
a successor agent (the "Successor Agent") who shall be acceptable to the
Borrower, acting reasonably. If no Successor Agent shall have been so appointed
by the Lenders and shall have accepted such appointment within 30 days after the
retiring Agent's giving of notice of resignation, then the retiring Agent shall,
on behalf of the Lenders, appoint a Successor Agent who shall be a Lender
acceptable to the Borrower, acting reasonably. Upon the acceptance of any
appointment as Agent hereunder by a Successor Agent, such Successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall thereupon be
discharged from its further duties and obligations as Agent under this
Agreement. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Article shall continue to enure to its benefit as to any
actions taken or omitted to be taken by it as Agent or in its capacity as Agent
while it was Agent hereunder.

      (2) Notwithstanding Section 14.10(1), no Lender shall become the Agent
unless such Lender's Commitment constitutes 10.0% or more of all outstanding
Commitments; accordingly, an Agent may not resign unless the Successor Agent
meets this requirement.
<PAGE>

                                      -79-

14.11 Taking and Enforcement of Remedies

      Each of the Lenders hereby acknowledges that, to the extent permitted by
applicable law, the remedies provided hereunder to the Lenders are for the
benefit of the Lenders collectively and acting together and not severally and
further acknowledges that its rights hereunder are to be exercised not
severally, but collectively by the Agent upon the decision of the Majority of
the Lenders regardless of whether acceleration was made pursuant to Section
11.2.  Notwithstanding any of the provisions contained herein, each of the
Lenders hereby covenants and agrees that it shall not be entitled to
individually take any action with respect to the Credit Facilities, including,
without limitation, any acceleration under Section 11.2, but that any such
action shall be taken only by the Agent with the prior written agreement or
instructions of the Majority of the Lenders; provided that, notwithstanding the
foregoing, if (i) the Agent, having been adequately indemnified against costs
and expenses of so doing by the Lenders, shall fail to carry out any such
instructions of a Majority of the Lenders, any Lender may do so on behalf of all
Lenders and shall, in so doing, be entitled to the benefit of all protections
given the Agent hereunder or elsewhere, and (ii) in the absence of instructions
from the Majority of the Lenders and where in the sole opinion of the Agent the
exigencies of the situation warrant such action, the Agent may without notice to
or consent of the Lenders or any of them take such action on behalf of the
Lenders as it deems appropriate or desirable in the interests of the Lenders.
Each of the Lenders hereby further covenants and agrees that upon any such
written consent being given by the Majority of the Lenders, or upon a Lender or
the Agent taking action as aforesaid, it shall cooperate fully with the Lender
or the Agent to the extent requested by the Lender or the Agent in the
collective realization including, without limitation, and, if applicable, the
appointment of a receiver, or receiver and manager to act for their collective
benefit.  Each Lender covenants and agrees to do all acts and things and to
make, execute and deliver all agreements and other instruments, including,
without limitation, any instruments necessary to effect any registrations, so as
to fully carry out the intent and purpose of this Section; and each of the
Lenders hereby covenants and agrees that, subject to Section 14.4 and Section
9.2(b) it has not heretofore and shall not seek, take, accept or receive any
security for any of the obligations and liabilities of the Borrower hereunder or
under any other document, instrument, writing or agreement ancillary hereto and
shall not enter into any agreement with any of the parties hereto or thereto
relating in any manner whatsoever to the Credit Facilities, unless all of the
Lenders shall at the same time obtain the benefit of any such security or
agreement.

      With respect to any enforcement, realization or the taking of any rights
or remedies to enforce the rights of the Lenders hereunder, the Agent shall be a
trustee for each Lender, and all monies received from time to time by the Agent
in respect of the foregoing shall be held in trust and shall be trust assets
within the meaning of applicable bankruptcy or insolvency legislation and shall
be considered for the purposes of such legislation to be held separate and apart
from the other assets of the Agent, and each Lender shall be entitled to their
Rateable Portion of such monies. In its capacity as trustee, the Agent shall be
obliged to exercise only the degree of care it would exercise in the conduct and
management of its own business and in accordance with its usual practice
concurrently employed or hereafter instituted for other substantial commercial
loans.
<PAGE>

                                      -80-

14.12 Reliance Upon Agent

      The Borrower shall be entitled to rely upon any certificate, notice or
other document or other advice, statement or instruction provided to it by the
Agent pursuant to this Agreement, and the Borrower shall generally be entitled
to deal with the Agent with respect to matters under this Agreement which the
Agent is authorized to deal with without any obligation whatsoever to satisfy
itself as to the authority of the Agent to act on behalf of the Lenders and
without any liability whatsoever to the Lenders for relying upon any
certificate, notice or other document or other advice, statement or instruction
provided to it by the Agent, notwithstanding any lack of authority of the Agent
to provide the same.

14.13 No Liability of Agent

      The Agent shall have no responsibility or liability to the Borrower on
account of the failure of any Lender to perform its obligations hereunder
(unless such failure was caused, in whole or in part, by the Agent's failure to
observe or perform its obligations hereunder), or to any Lender on account of
the failure of the Borrower or any Lender to perform its obligations hereunder.

14.14 Article for Benefit of Agents and Lenders

      The provisions of this Article Fourteen which relate to the rights and
obligations of the Lenders to each other or to the rights and obligations
between the Agent and the Lenders shall be for the exclusive benefit of the
Agent and the Lenders, and, except to the extent provided in Sections 14.1,
14.2, 14.6, 14.10, 14.11, 14.12, 14.13 and this Section 14.14, the Borrower
shall not have any rights or obligations thereunder or be entitled to rely for
any purpose upon such provisions.  Any Lender may waive in writing any right or
rights which it may have against the Agent or the other Lenders hereunder
without the consent of or notice to the Borrower.


                                  ARTICLE 15
                                    GENERAL

15.1  Exchange and Confidentiality of Information

      (1) The Borrower agrees that the Agent and each Lender may provide any

of an Event of Default and at all other times with the prior written consent of
the Borrower and the Agent, which consents shall not be unreasonably withheld,
sell, assign, transfer or grant an interest in its Commitments and its Rateable
Portion of the Loans; provided that, without the consent of the Borrower and the
Agent, no Lender shall sell, assign, transfer or grant an interest in any
Commitment or Loan if the effect of the same would be to have a Lender with

the granting Lender shall have no further obligation hereunder with respect to
such interest except in case of a grant to a person affiliated with the granting
Lender (determined in accordance with the Bank Act (Canada)), in which case such
Lender shall remain obligated hereunder with respect to such interest.  Upon any
such sale, assignment, transfer or grant, the granting Lender, the new Lender,
the Agent and the Borrower shall execute and deliver an assignment agreement.
Subject to the provisions of Section 9.2(i), the Borrower shall not assign its
rights or obligations hereunder without the prior written consent of all

participations in its Commitment and its Rateable Portion of the Loans to other
financial institutions, provided that the granting of such a participation shall
be at the Lender's own cost and shall not affect the obligations of such Lender
hereunder nor shall it increase the costs to the Borrower hereunder or under any
of the other Documents and such Lender shall remain solely liable and
responsible for all of its Commitment in respect of all of the Documents and the
Borrower shall be entitled to deal exclusively with such Lender in relation
thereto.
