Payments received following the Reference Date pro rata to their respective
proportions of the Combined Outstandings.

3.2      PAYMENTS TO CURE BORROWING BASE DEFICIENCY

         Upon the delivery of a notice of Borrowing Base Deficiency to the U.S.
Borrower under Section 3.2(b)(2) of the U.S. Credit Agreement, the
Administrative Agents shall determine the Sharing Percentages of the Canadian
Lenders and the U.S. Lenders at the time of such notice.  The U.S. Borrower and
the Canadian Borrower agree that any payments required to cure such Borrowing
Base Deficiency shall be made by the U.S. Borrower to the U.S. Lenders and by
the Canadian Borrower to the Canadian Lenders (with the Maximum Outstanding
Amount--as such term is defined in the Canadian Credit Agreement--to be reduced
by the amount of such payments by the Canadian Borrower) in accordance with
their respective Sharing Percentages as so determined.  For this purpose, if
any such payment is made in Canadian Dollars under the Canadian Credit
Agreement, the Equivalent U.S. Dollar Amount thereof shall be considered to
have been made.  For purposes of this Section 3.2, the Sharing Percentages of
the Lenders shall be recalculated as of each January 1, April 1, June 1 and
September 1 using the Combined Outstandings at the time of the applicable
notice of Borrowing Base Deficiency but using the then current Equivalent U.S.
Dollar Amount with respect to any of such Combined Outstandings denominated in
Canadian Dollars.

3.3      EQUALIZATION FOLLOWING THE OCCURRENCE OF THE REFERENCE DATE

         a.      As of the Reference Date, the Operative Sharing Percentages of
the respective Lenders shall be determined.

         b.      Upon any receipt by any Administrative Agent (or by the Paying
Agent under the





                                       9
   10
                 Canadian Credit Agreement) of any Reallocable Payments (after
                 giving effect to application of such receipts), the Post
                 Default Proportions of the U.S. Lenders and the Canadian
                 Lenders shall be determined.

         c.      If the Post Default Proportion of the U.S. Lenders and the
                 Post Default Proportion of the Canadian Lenders calculated
                 pursuant to Section 3.3.b above are not equal to their
                 respective Operative Sharing Percentages, then the Lenders
                 whose Post Default Proportion is less than their Operative
                 Sharing Percentages shall firstly, repurchase participations
                 previously sold by them to other Lenders (such participation
                 interests to be allocated pro rata among the sellers in
                 accordance with their respective Operative Sharing
                 Percentages) and then purchase participations in the U.S.
                 Credit Outstandings or the Canadian Credit Outstandings, as
                 the case may be (such participation interests to be allocated
                 pro rata among the sellers in accordance with their respective
                 Operative Sharing Percentages), in U.S. Dollars on a
                 non-recourse basis so that, after such payment by the
                 purchasing Lenders and receipt thereof by the selling Lenders,
                 their respective Post Default Proportions shall equal their
                 Operative Sharing Percentages; provided, however, that if
                 after any amount is paid under this Section 3.3.c. a Borrower
                 or any trustee, liquidator, receiver or receiver-manager or
                 Person with analogous powers recovers any amount from any
                 Lenders ("Disgorging Lenders") in respect of any amount
                 theretofore applied to the U.S. Credit Outstandings or the
                 Canadian Credit Outstandings, then such amount (including any
                 interest paid by the Lenders) shall be treated for all
                 purposes:

                 i.       as between the relevant Borrower and the Disgorging
                          Lenders; and

                 ii.      as between the Disgorging Lenders and the other
                          Lenders (the "Non-Disgorging Lenders"),

                 to be outstanding as U.S. Credit Outstandings or Canadian
                 Credit Outstandings (as applicable), in which case the Post
                 Default Proportions shall thereupon be adjusted and this
                 Section 3.3.c. again applied.

         d.      Notwithstanding anything contained in this Agreement or the
                 Credit Agreements, the purchase of participations in the
                 Canadian Credit Outstandings hereunder by the U.S. Lenders and
                 the acquisition of an undivided interest in any property by
                 the U.S. Lenders from any Canadian Lender or the Canadian
                 Agent or the Paying Agent, as the case may be, pursuant to
                 Section 6.12 hereof shall not constitute an acquisition by the
                 U.S. Lenders of any beneficial interest in the Canadian Credit
                 Agreement or any amount owing thereunder but shall constitute
                 risk sharing payments among the Canadian Lenders and the U.S.
                 Lenders and the beneficial interest in the Canadian Credit
                 Agreement and all amounts owing thereunder shall at all times
                 remain with the Canadian Lenders.

rise to any liability for any withholding tax payments in connection with any
payments made by the Canadian Borrower, the U.S. Borrower, the Guarantor or any
other Relevant Party under either of the Credit Agreements, then
(notwithstanding any provisions to the contrary set forth in either of the
Credit Agreements), the Borrowers, jointly and severally, shall indemnify each
of the applicable Lenders and shall hold each of the applicable Lenders
harmless from and against any such liability; provided, however, that each of
the Lenders (if so requested by the Borrower under its Credit Agreement through
the Administrative Agent) will use good faith efforts to accommodate any
reasonable request by such Borrower in order to avoid the need for, or reduce
the amount of, such compensation so long as the request will not, in the sole
opinion of the applicable Lender, be disadvantageous to such Bank.
