FINANCING COMMITMENT
FOR
CARBON ENERGY CANADA CORPORATION

This Financing Commitment constitutes the whole and entire agreement between the Borrower, CIBC and PLC and cancels and supersedes any prior agreements, undertakings, declarations, representations and warranties, written or verbal, among the parties in respect of the subject matter of this Financing Commitment, including any prior Financing Commitment or arrangements.

MAY 14, 2003

BORROWER: Carbon Energy Canada Corporation (the "Borrower")

GUARANTOR: Carbon Energy Corporation (the "Guarantor")

LENDER: Canadian Imperial Bank of Commerce ("CIBC")

GAS PURCHASE AND SALE TRANSACTIONS FACILITATOR: CIBC World Markets PLC or any other subsidiary of CIBC from time to time ("PLC")

CONFIDENTIALITY: The contents of this Financing Commitment are confidential and shall not be disclosed in whole or part to any unaffiliated third party, except to their professional advisers in connection herewith and as otherwise required by law.

EXISTING FACILITY: This Financing Commitment replaces the existing facility already provided by CIBC to the Borrower (formerly named CEC Resources Ltd.) as set forth in CIBC's financing commitment dated May 9, 2002 (the "Existing Facility"), such that all indebtedness of the Borrower to CIBC under the Existing Facility will be deemed to be an Advance under this Facility and subject to the terms and conditions of this Facility.

AMOUNT: Cdn. $22,000,000 as an Extendible Revolving Term Credit Facility (the "Credit Facility") and,

U.S. $5,000,000 as a swap facility (the "Swap Facility")

(collectively, the "Facility").

PURPOSE OF THE FACILITY: Credit Facility For normal operating requirements and to assist the Borrower in the exploration, development, production and/or acquisition of oil and gas reserves in Western Canada.

Swap Facility To provide for the Borrower's contingent exposure under commodity swaps either financially or physically settled.

HOSTILE ACQUISITION: The Borrower shall not utilize whether directly or indirectly Availments to facilitate, assist or participate in a hostile acquisition without the prior written consent of CIBC, which consent may be withheld in CIBC's sole discretion.

BORROWING BASE: Subject to the satisfaction of the conditions precedent under the heading "Conditions Precedent to Funding", the Credit Facility currently permits draws of up to Cdn. $22,000,000 (the "Borrowing Base"), subject to adjustment as herein provided, and will remain in effect until expiration of the Revolving Phase.

CIBC will undertake at any time, but not less frequently than semi-annually, a review of the Borrower's oil and gas properties evaluated in an independently prepared economic and reserve evaluation report (to be provided by the Borrower annually and from time to time as reasonably requested by CIBC) for purposes of redetermining the Borrowing Base applicable to the Facility. To assist in such redetermination, the Borrower will provide to CIBC operating statements and such other

technical information with respect to the properties being reviewed as CIBC may request. The next review is to occur on or before September 30, 2003.

Should CIBC determine at any time that there is a Borrowing Base Shortfall, during either the Revolving Phase and the Term Phase, the Borrower will, within 60 days, use whatever means necessary to reduce its indebtedness under this Financing Commitment by that amount stipulated by CIBC, or alternatively pledge additional security to CIBC sufficient to cover, in CIBC's opinion, such deficiency.

While a Borrowing Base Shortfall exists, the Borrower shall:

•: not request new Availments;
•: provide CIBC with information needed to determine the Borrower's Available Cash Flow;
•: dedicate on a monthly basis for repayment of this Financing Commitment such portion of its Available Cash Flow as is required to eliminate the Borrowing Base Shortfall within 60 days from the date CIBC delivers notice to the Borrower of the Borrowing Base Shortfall (the "Shortfall Notice") with the first such repayment being due 30 days after the date of the Shortfall Notice and further payments will be required every 30 days thereafter while a Borrowing Base Shortfall exists; and
•: pay the increased compensation required under the heading "Borrowing Base Rate Shortfall or Event of Default".

TOTAL DEBT: To determine Principal Indebtedness, outstanding borrowings in U.S. Dollars will be the Cdn. Dollar Exchange Equivalent thereof.

To the extent the Borrower does not have sufficient U.S. Dollar revenue to service the U.S. Dollar borrowings under the Facility such borrowings, in an amount to be determined by CIBC, must be hedged to CIBC's satisfaction acting reasonably.

CREDIT FACILITY AVAILABILITY: The Credit Facility can be advanced by way of any combination of the following Availments:

•: overdraft borrowings in Cdn. Dollars;
•: banker's acceptances in Cdn. Dollars, in minimum aggregate amounts of Cdn. $2,500,000 for each drawdown, rollover or conversion and in minimum incremental amounts of Cdn. $500,000 thereafter;
•: direct borrowings in Cdn. Dollars and/or U.S. Dollars
•: LIBOR borrowings in U.S. Dollars, in minimum aggregate amounts of U.S. $2,500,000 for each drawdown, rollover or conversion and in minimum incremental amounts of U.S. $500,000 thereafter; and
•: letters of credit, letters of guarantee, cheque credits and corporate visa (collectively the "Sundry Options").

SWAP FACILITY AVAILABILITY: At the Borrower's request and subject to market availability, CIBC and/or PLC will provide quotes for (i) forward rate agreements to provide fixed or floating rate funding for part or all of the Credit Facility, (ii) commodity swaps covering a portion of the Borrower's oil and gas production, (iii) forward exchange contracts and (iv) firm gas purchase and sale transactions, subject to the following:

•: Forward Rate Agreements—terms shall not exceed the lesser of two years and the date of expiry or termination of the Credit Facility, with aggregate amounts hedged not to exceed 60% of the average Principal Indebtedness outstanding during the Borrower's previous fiscal quarter;

•: Commodity Swaps—terms shall not exceed the lesser of two years and the date of expiry or termination of the Credit Facility, with aggregate production volumes hedged from all sources, for both natural gas and oil, (calculated separately, not collectively) not to exceed 60% of the Borrower's net average production as forecast by CIBC.
•: Forward Exchange Contracts—terms shall not exceed the lesser of two years and the date of expiry or termination of the Credit Facility, with aggregate amounts hedged not to exceed 60% of the Borrower's applicable foreign revenue;
•: Physical Gas Purchase and Sale Transactions—terms and conditions as outlined in the Master Firm Gas Purchase/Sale Agreement, terms shall not exceed the lesser of two years and the date of expiry or termination of the Credit Facility, with aggregate production volumes hedged from natural gas not to exceed 60% of the Borrower's current daily production volume as determined by CIBC;

provided that in all instances, the Borrower's contingent liability to CIBC and/or PLC under the Swap Facility shall be secured and rank pari passu with the Principal Indebtedness.

Notwithstanding the foregoing, the sum of the aggregate production volumes hedged with CIBC and/or PLC from natural gas under both the commodity swaps and physical gas purchase and sale transactions described above shall not at any time exceed 60% of the Borrower's current daily production volumes of natural gas as determined by CIBC.

TERM AND REPAYMENT: The Credit Facility will revolve and fluctuate at the Borrower's option until March 31, 2004 (the "Revolving Phase") with interest payable monthly in arrears, or with respect to LIBOR borrowings, as otherwise provided herein. At the request of the Borrower, the Credit Facility may be renewed upon such terms and for such period, and subject to the requirements listed below, as CIBC may in its discretion agree to (a "Revolving Period"). CIBC may elect to renew all or only a portion of the Credit Facility for a further Revolving Phase.

Revolving Phase While the Credit Facility is in the Revolving Phase, the Borrower may, at least 60 days prior to the termination of the then current Revolving Phase, request an extension of the Revolving Phase provided:

•: the extension is for 364 days or less;
•: the extension will not result in the then current Revolving Period extending beyond 364 days; and
•: CIBC, in its unrestricted discretion, consents to the extension.

An extension of the Revolving Phase will create a new and separate Revolving Phase which in turn can only be extended as provided above. If the Borrower does not make the request during the required period described above or if CIBC does not agree to such an extension, then the Revolving Phase will expire on the last day of the Revolving Phase.

Upon the expiration or termination of the then current Revolving Phase, any amount undrawn under the Credit Facility will be permanently cancelled.

Term Phase During the Term Phase, the Credit Facility will be permanently reduced by way of consecutive monthly principal payments commencing 30 days after the end of the Revolving Phase over an amortization period consistent with the Borrower's cash flow profile, as determined by CIBC, by applying its usual practice for similar type loans in comparable circumstances, provided that such amortization period shall not exceed 24 months. On the last day of the Term Phase, all principal, interest and other amounts owing hereunder will become immediately due and payable.

Where used herein, the term "Term Phase" means the period commencing immediately after the end of the Revolving Phase until repayment of the Credit Facility in full.

PREPAYMENT AND CANCELLATION: The Borrower may permanently prepay the Facility in whole or in part, subject to the following:

•: Availments by way of bankers' acceptances may only be paid at maturity dates.
•: All prepayments, during the Term Phase, will be made in inverse order of maturity.
•: Availments by way of commodity swaps (financial or physical), forward rate agreements and forward exchange contracts may be prepaid only at maturity except where the Borrower agrees to pay CIBC's breaking costs due to early redemption of offsetting positions or otherwise, including all costs associated with reversing positions, provided such early redemption is possible.
•: Availments by way of LIBOR borrowings may be prepaid only at maturity except where the Borrower agrees to pay CIBC's breaking costs due to early redemption of offsetting deposits or otherwise, provided such early redemption is possible.
•: The Borrower may at any time, upon giving CIBC two Banking Days prior notice, cancel any unused part of the Facility and any cancelled portion will not be reinstated.

2.3 Irrevocability. A notice of borrowing, notice of rollover or notice of conversion shall be in such form as the Borrower and CIBC agree and when given by the Borrower shall be irrevocable and shall oblige the Borrower and CIBC to take the action contemplated herein and therein on the date specified therein.

2.4 Rollover or Conversion of Availments

(a) The Borrower shall be entitled to rollover one type of Availment into the same type of Availment or convert one type of Availment into another type of Availment on the terms herein provided.

(b) If the Borrower fails to give CIBC a duly completed notice of rollover or notice of conversion if and as required, or if in giving such notice the Borrower fails to provide for the rollover or conversion of all of the Availment then maturing, the Borrower shall be deemed to have irrevocably elected to convert a maturing advance, or that part of such maturing advance which the Borrower has failed to provide for in such notice, as the case may be, into a CIBC Prime Rate loan with respect to a Cdn. Dollar borrowing or a U.S. Base Rate loan with respect to a U.S. Dollar borrowing.

ARTICLE 3
CALCULATION OF INTEREST AND FEES

3.1 Records. CIBC shall maintain records, in written or electronic form, evidencing all advances and all other indebtedness owing by the Borrower to CIBC under this Financing Commitment. CIBC shall enter in such records details of all amounts from time to time owing, paid or prepaid by the Borrower to it hereunder. The information entered in such records shall constitute prima facie evidence of the indebtedness of the Borrower to CIBC under this Financing Commitment.

3.2 Payment of Interest and Fees.

(a) Interest. Except as expressly stated otherwise herein, all CIBC Prime Rate loans, U.S. Base Rate loans and LIBOR based loans from time to time outstanding hereunder shall bear interest, as well after as before maturity, default and judgment, with interest on overdue interest, at the applicable rates. Interest payable at a variable rate shall be adjusted automatically without notice to the Borrower whenever there is a variation in such rate.

(b) Calculation of Interest and Stamping Fees. Interest on CIBC Prime Rate loans and U.S. Base Rate loans shall accrue and be calculated daily and be payable on such Banking Day as is customary for CIBC having regard to its then existing practice. Interest on CIBC Prime Rate loans and U.S. Base Rate loans and stamping fees on bankers' acceptances shall be calculated on the basis of a 365 day year.

(c) Interest Act (Canada). For the purposes of the Interest Act (Canada) and all other applicable laws which may hereafter regulate the calculation or computation of interest in this Financing Commitment, the annual rates of interest and fees applicable to CIBC Prime Rate loans and U.S. Base Rate loans and stamping fees on bankers' acceptances, respectively, are the rates as determined under this Financing Commitment multiplied by the actual number of days in a period of one year commencing on the first day of the period for which such interest or stamping fee is payable and divided by 365.

(d) LIBOR Based Loans. Interest on LIBOR based loans shall accrue and be calculated daily and be payable at the end of each applicable LIBOR period, provided that, where the LIBOR period exceeds 90 days, interest shall be calculated and payable every 90 days during the term of the LIBOR period and on the last day of the applicable LIBOR period. Interest on LIBOR based loans shall be calculated on the basis of the actual number of days in each LIBOR period divided by 360. For the purposes of the Interest Act (Canada) and other applicable laws, the annual rates of interest applicable to LIBOR based loans are the rates as determined hereunder multiplied by the actual number of days in a period of one year commencing on the first day of the period for which such interest is payable and divided by 360.

3.3 Conversion to Another Currency. A conversion of an advance from one currency to another currency shall not be made by a netting out of funds unless agreed upon by CIBC.

3.4 Waiver of Judgment Interest Act (Alberta). To the extent permitted by applicable law, the provisions of the Judgment Interest Act (Alberta) shall not apply to this Financing Commitment and are hereby expressly waived by the Borrower.

3.5 Deemed Reinvestment Not Applicable. For the purposes of the Interest Act (Canada), the principle of deemed reinvestment of interest shall not apply to any interest calculation under this Financing Commitment and the rates of interest stipulated in this Financing Commitment are intended to be nominal rates and not effective rates or yields.

(b) Issuance fees in respect of letters of credit and letters of guarantee shall be calculated on the face amount thereof and shall be payable annually in advance commencing on the date of issuance.

(a) payment thereof in full; or

(b) utilization of another Availment; or

4.4 Reliance. CIBC shall be entitled to honour each demand made under a letter of credit or letter of guarantee in accordance with the terms thereof without inquiring as to the propriety, sufficiency or genuineness of any such demand, provided that if the letter of credit or letter of guarantee is a documentary letter of credit or letter of guarantee, CIBC must receive to CIBC's satisfaction the required documents in the prescribed form under applicable law prior to honouring any such demand.

GENERAL PROVISIONS RELATING TO LIBOR BASED LOANS

5.1 General.

(a) The aggregate amount of each advance by way of a LIBOR based loan shall be at least U.S. $2,500,000 and in multiples of U.S. $500,000 for any amount in excess thereof.

(b) If the Borrower elects an Availment by way of a LIBOR based loan or a rollover or a conversion into a LIBOR based loan, the Borrower shall specify in its notice of borrowing, notice

of rollover or notice of conversion, as applicable, the LIBOR period (which shall begin and end on a Banking Day) applicable to such LIBOR based loan.

5.2 Inability to Make LIBOR Based Loans. If on any date CIBC determines in good faith (which determination shall be conclusive as between the parties hereto), that its ability to make a requested LIBOR based loan has become impracticable, impossible or unlawful, or has been materially adversely affected, because:

(a) of any change in applicable law or in the interpretation or administration thereof by authorities having jurisdiction in the matter, whether or not having the force of law;

(b) of any material adverse change in, or the termination of, the London Interbank Eurodollar Market for eurodollars; or

then CIBC shall give the Borrower written notice thereof and thereupon, CIBC shall have no further obligation with respect to such LIBOR based loan, provided that, the Borrower may elect to drawdown, rollover or convert the amount originally requested by way of such LIBOR based loan, into some other type of Availment upon compliance with the applicable notice requirements set out herein.

ARTICLE 6
BANKERS' ACCEPTANCES

6.1 General. Each bankers' acceptance draft tendered by the Borrower for acceptance by CIBC shall be in a form acceptable to CIBC and the advance in respect thereof shall be in a principal amount of not less than Cdn. $2,500,000 and in multiples of Cdn. $500,000 for any amounts in excess thereof and shall have a term of not less than 30 days and not more than 180 days, unless otherwise agreed to by the CIBC.

6.2 Terms of Acceptance by CIBC.

(a) Power of Attorney. To facilitate the procedures contemplated in this Agreement, the Borrower appoints CIBC from time to time as the attorney-in-fact of the Borrower to execute, endorse and deliver on behalf of the Borrower drafts or depository bills in the form or forms prescribed by CIBC for bankers' acceptances denominated in Canadian Dollars (each such executed draft or depository xxxx which has not yet been accepted by CIBC being referred to as a "Draft"). Each bankers' acceptance executed and delivered by CIBC on behalf of the Borrower as provided for in this Section 6.2(a) will be as binding upon the Borrower as if it had been executed and delivered by a duly authorized officer of the Borrower. The foregoing appointment will cease to be effective three Banking Days following receipt by CIBC of a notice from the Borrower revoking such appointment provided that any such revocation will not affect bankers' acceptances previously executed and delivered by CIBC pursuant to such appointment.

(b) Payment. The Borrower shall provide for payment to CIBC of each bankers' acceptance at its maturity, either by payment of the face amount thereof or through the utilization of an Availment in accordance with this Financing Commitment, or through a combination thereof. The Borrower waives presentment for payment of bankers' acceptances by CIBC and shall not claim from CIBC any days of grace for the payment at maturity of bankers' acceptances. Any amount owing by the Borrower in respect of any bankers' acceptance which is not paid in accordance with the foregoing, shall, as and from its maturity date, be deemed to be outstanding hereunder as a CIBC Prime Rate loan.

(c) No Liability. CIBC shall not be liable for any damage, loss or improper use of any bankers' acceptance draft endorsed in blank except for any loss arising by reason of CIBC failing

to use the same standard of care in the custody of such bankers' acceptance drafts as CIBC uses in the custody of its own property of a similar nature.

(d) Marketing of Bankers' Acceptances. The Borrower shall be responsible for, and shall make its own arrangements with respect to, the sale of bankers' acceptances in the market place. Notwithstanding the foregoing, CIBC may purchase from the Borrower for its own account any bankers' acceptance issued by it at a discount rate to be agreed upon between the Borrower and CIBC.

(e) Depository Bills. It is the intention of the Borrower and CIBC that pursuant to the Depository Bills and Notes Act("DBNA"), all bankers' acceptances accepted by CIBC under the Financing Commitment shall be issued in the form of a "depository xxxx" (as defined in the DBNA), deposited with the Canadian Depository for Securities Ltd. ("CDS") and will be made payable to CDS & Co. In order to give effect to the foregoing, CIBC shall, subject to the approval of the Borrower, such approval not to be unreasonably withheld, establish and notify the Borrower of any additional procedures, consistent with the terms of the Financing Commitment and the requirements of the DBNA, as are reasonably necessary to accomplish such intention, including, without limitation:

(i) any instrument held by CIBC for the purposes of bankers' acceptances shall have marked prominently, and legibly on its face and within its text, at or before the time of issue, the words "This is a depository xxxx subject to the Depository Bills and Notes Act (Canada)";

(ii) any reference to the authentication of the bankers' acceptance will be removed; and

(iii) any reference to "bearer" will be removed and such bankers' acceptance shall not be marked with any words prohibiting negotiation, transfer or assignment of it or of an interest in it.

(f) Records. As a condition precedent to CIBC's obligation to accept bankers' acceptances hereunder, the Borrower shall have either delivered to CIBC at the branch of account used by the Borrower sufficient bankers' acceptances executed in blank in sufficient time for CIBC to forward to and hold same at its Toronto offices for issuance in accordance with a request from the Borrower or provide CIBC with an authorization in a form acceptable to it, authorizing the designated securities officers of CIBC to complete and issue such bankers' acceptances and, on behalf of the Borrower, to sign such bankers' acceptances as drawer by affixing a reproduction of the signatures of CIBC's designated securities officers thereon. CIBC will not be liable for any damage, loss or other claim arising by reason of any loss or improper use of any such bankers' acceptance endorsed in blank except any loss arising by reason of CIBC or its officers, employees, agents or representatives failing to use the same standard of care in the custody of such bankers' acceptances executed in blank as CIBC uses in the custody of its own property of a similar nature. CIBC will shall maintain a record with respect to such bankers' acceptances endorsed in blank that are:

(i) received by CIBC from the Borrower;

(ii) voided by CIBC for any reason;

(iii) accepted by CIBC hereunder; and

(iv) cancelled by CIBC at the maturity thereof.

6.3 General Mechanics.

(a) Notice. Subject to Section 2.4 of this Schedule "A", the Borrower may in the notice of borrowing, notice of rollover or notice of conversion requesting an Availment by way of bankers' acceptances or by subsequent notice to CIBC, provide CIBC with information as to the discount proceeds payable by the purchasers of the bankers' acceptances and the party to whom delivery of

the bankers' acceptances is to be made against delivery of such discount proceeds to CIBC for the credit of the Borrower.

(b) Rollovers. In the case of a rollover of maturing bankers' acceptances, CIBC, in order to satisfy the continuing liability of the Borrower to CIBC for the face amount of the maturing bankers' acceptances, shall retain for its own account the net proceeds of each new bankers' acceptance issued by it in connection with such rollover and the Borrower shall, on the maturity date of the maturing bankers' acceptances, pay to CIBC an amount equal to the difference between the face amount of the maturing bankers' acceptances and the aggregate net proceeds of the new bankers' acceptances.

(c) Conversion from Canadian Dollar Availments. In the case of a conversion from a CIBC Prime Rate loan into an Availment by way of bankers' acceptances, CIBC, in order to satisfy the continuing liability of the Borrower to CIBC for the principal amount of the CIBC Prime Rate loan being converted, shall retain for its own account the net proceeds of each new bankers' acceptance issued by it in connection with such conversion and the Borrower shall, on the date of issuance of the bankers' acceptances pay to CIBC an amount equal to the difference between the aggregate principal amount of the CIBC Prime Rate loan being converted, including any accrued interest thereon, owing to CIBC and the aggregate net proceeds of such bankers' acceptances.

(d) Conversion to Canadian Dollar Availment. In the case of a conversion of an Availment by way of bankers' acceptances into a CIBC Prime Rate loan, CIBC, in order to satisfy the liability of the Borrower to CIBC for the face amount of the maturing bankers' acceptances, shall record the obligation of the Borrower to it as a CIBC Prime Rate loan, unless the Borrower provides for payment to CIBC of the face amount of the maturing bankers' acceptance in some other manner acceptable to CIBC.

(e) Authorization. The Borrower hereby authorizes CIBC to complete, stamp, hold, sell, rediscount or otherwise dispose of all bankers' acceptances accepted by it in accordance with the instructions provided by the Borrower hereunder.

6.4 Escrowed Funds. Upon the occurrence of an Event of Default, the Borrower shall forthwith pay to CIBC for deposit into an escrow account maintained by and in the name of CIBC an amount equal to CIBC's maximum potential liability under then outstanding bankers' acceptances, letters of credit and other similar Availments, including CIBC's contingent exposure under swap contracts entered into with the Borrower (the "Escrow Funds"). The Escrow Funds shall be held by CIBC for set-off against future indebtedness owing by the Borrower to CIBC in respect of such bankers' acceptances and pending such application shall bear interest at the rate declared by CIBC from time to time as that payable by it in respect of deposits for such amount and for the period from the date of deposit to the maturity date of the bankers' acceptances. If such Event of Default is either waived or cured in compliance with the terms of this Financing Commitment, then the remaining Escrow Funds if any, together with any accrued interest to the date of release, shall be released to the Borrower

6.5 Execution of Bankers' Acceptances. The signatures of any authorized signatory on bankers' acceptances may, at the option of the Borrower, be reproduced in facsimile and such bankers' acceptances bearing such facsimile signatures shall be binding on the Borrower as if they had been manually signed by such authorized signatory. Notwithstanding that any person whose signature appears on any bankers' acceptance as a signatory may no longer be an authorized signatory of the Borrower at the date of issuance of a bankers' acceptance, and notwithstanding that the signature affixed may be a reproduction only, such signature shall nevertheless be valid and sufficient for all purposes as if such authority had remained in force at the time of such issuance and as if such signature had been manually applied, and any such bankers' acceptance so signed shall, subject to Section 6.2 of this Schedule "A", be binding on and at the risk of the Borrower.

ARTICLE 7
OVERDRAFT BORROWINGS

7.1 Overdraft Borrowings.

(a) At any time that the Borrower would be entitled to obtain CIBC Prime Rate loans under the Credit Facility, it will be entitled to draw cheques on its Cdn. Dollar chequing account number 96-02216 Transit # 9 at CIBC's 000- 0^xx Xxxxxx X.X., Xxxxxxx, Xxxxxxx xxxxxx. The debit balance from time to time in any such account will be deemed to be a CIBC Prime Rate loan outstanding to the Borrower under the Credit Facility. If at any time the Borrower is a party to a cash concentration arrangement with CIBC, the amount of any overdraft from time to time in the Cdn. Dollar concentration account of the Borrower established pursuant to such arrangement will also be deemed to be a CIBC Prime Rate loan outstanding to the Borrower under the Credit Facility.

(b) The Borrower agrees to repay all overdrafts on demand, together with interest calculated on the daily balance of the amount owing and payable monthly, both before and after demand and judgment, at the rates described in this Financing Commitment with interest on overdue interest at the same rate; provided the interest rate hereunder will vary automatically on the day such rate is varied by CIBC and without notice by CIBC to the Borrower. Interest charges may be debited to the account designated above.

(c) The Borrower agrees not to make any drawings which would cause the Credit Facility limit or the Borrowing Base to be exceeded and CIBC reserves the right to refuse to honour any drawing which in CIBC's opinion would have the effect of causing the Credit Facility limit or the Borrowing Base to be exceeded.

(d) Notwithstanding that the Credit Facility is restricted to the amount set out herein and to the account designated above, any overdraft which may occur in excess of the Credit Facility limit or the Borrowing Base or which may occur in other accounts of the Borrower, will be governed by the provisions hereof, except that the rate of interest will be calculated at a variable nominal rate per annum equal to CIBC's standard overdraft rate as declared by CIBC from time to time with interest on overdue interest at the same rate, such rate to vary automatically on the day the standard overdraft rate is varied by CIBC and without notice by CIBC to the Borrower. CIBC's standard overdraft rate on the date hereof is 21 per cent per annum.

ARTICLE 8
INCREASED COSTS

(ii) the compliance with any guideline or request from any central bank or other administrative body which CIBC, acting reasonably, determines that it is required to comply with,

there shall be any increase in the cost to CIBC of agreeing to make or making, funding or maintaining this Financing Commitment or there shall be any reduction in the effective return to CIBC thereunder, then, subject to the paragraph below, the Borrower shall, within 5 Banking Days after being notified by CIBC of such event, pay to CIBC quarterly in arrears, that amount (the

(b) If Additional Compensation is payable pursuant to the above paragraph, the Borrower shall have the option to prepay any amount of the Principal Indebtedness owed to CIBC, subject to provisions herein.

8.2 Changes in Circumstances. Notwithstanding anything to the contrary herein contained, if on any date CIBC determines in good faith, which determination shall be conclusive and binding on the parties, and provided written notice is given to the Borrower that its ability to maintain, or continue to offer any Availment has become unlawful or impossible due to:

(a) any change in applicable laws, or in the interpretation or administration thereof by authorities having jurisdiction in the matter;

(b) any material adverse change in, or the termination of, the London Interbank Eurodollar Market for eurodollars; or

then, in any such case, the Borrower shall forthwith repay to CIBC all principal amounts affected thereby, together with all unpaid interest accrued thereon to the date of repayment and all other expenses incurred in connection with the termination of any such Availment. The Borrower may utilize other forms of Availments not so affected in order to make any required repayment and after any such repayment, the Borrower may elect to re-borrow the amount repaid by way of some other Availment upon complying with applicable requirements thereof.

ARTICLE 9
