(ii) the Borrower or any of the Restricted Subsidiaries adopts a material change in an accounting policy in order to more appropriately present events or transactions in its financial statements;

and the above change would require disclosure under GAAP in the consolidated financial statements of the Borrower and would cause an amount required to be determined for the purposes of a financial covenant under Section 8.3 (a “Financial Covenant”) to be materially different than the amount that would be determined without giving effect to such change, the Borrower shall notify the Agent of such change (an “Accounting Change”). Such notice (an “Accounting Change Notice”) shall describe the nature of the Accounting Change, its effect on the current and immediately prior year’s financial statements in accordance with GAAP and state whether the Borrower desires to revise the method of calculating one or more of the Financial Covenants (including the revision of any of the defined terms used in the determination of such Financial Covenant) in order that amounts determined after giving effect to such Accounting Change and the revised method of calculating such Financial Covenant will approximate the amount that would be determined without giving effect to such Accounting Change and without giving effect to the revised method of calculating such Financial Covenant. The Accounting Change Notice shall be delivered to the Agent within 60 days of the end of the Fiscal Quarter in which the Accounting Change is implemented or, if such Accounting Change is implemented in the fourth Fiscal Quarter or in respect of an entire Fiscal Year, within 120 days of the end of such period.

(d) If either the Borrower or the Majority Lenders so indicate that they wish to revise the method of calculating one or more of the Financial Covenants, the Borrower and the Majority Lenders shall in good faith attempt to agree on a revised method of calculating the Financial Covenants. If, however, within 30 days of the foregoing notice by the Borrower or the Majority Lenders of their desire to revise the method of calculating one or more of the Financial Covenants, the Borrower and the Majority Lenders have not reached agreement in writing on such revised method of calculation, such method of calculation shall not be revised and all amounts to be determined thereunder shall be determined without giving effect to the Accounting Change. For greater certainty, if no notice of a desire to revise the method of calculating the Financial Covenants in respect of an Accounting Change is given by either the Borrower or the Majority Lenders within the applicable time period described above, the method of calculating the Financial Covenants shall not be revised in response to such Accounting Change and all

amounts to be determined pursuant to the Financial Covenants shall be determined after giving effect to such Accounting Change.

(e) If a Compliance Certificate is delivered in respect of a Fiscal Quarter or Fiscal Year in which an Accounting Change is implemented without giving effect to any revised method of calculating any of the Financial Covenants, and subsequently, as provided above, the method of calculating one or more of the Financial Covenants is revised in response to such Accounting Change, or the amounts to be determined pursuant to any of the Financial Covenants are to be determined without giving effect to such Accounting Change, the Borrower shall deliver a revised Compliance Certificate. Any Default or Event of Default which arises as a result of the Accounting Change and which is cured by this Section 1.9 shall be deemed to have never occurred.

(b) Notwithstanding the foregoing or any other term hereof, all of the covenants, representations and warranties on the part of the Borrower under the Existing Credit Agreement and all of the claims and causes of action arising against the Borrower in connection therewith, in respect of all matters, events, circumstances and obligations arising or existing prior to the Effective Date shall continue, survive and shall not be merged in the execution of this Agreement or any other Loan Documents or any advance or provision of any Advance hereunder.

CREDIT FACILITY

2.1 Establishment of Credit Facility

(a) Credit Facility. Subject to the terms and conditions of this Agreement, each Lender hereby severally agrees to make available, until the Maturity Date, Advances in an aggregate amount up to its Commitment (the “Credit Facility”) and, as part of its Commitment, the Swing Line Lender hereby severally agrees to make available Swing Line Advances up to its Swing Line Commitment.

The Credit Facility is a revolving credit facility and, prior to the Maturity Date, the Borrower may (i) borrow, repay and re-borrow Prime Loans, USBR Loans, Overdrafts and LIBOR Loans, (ii) issue, repay and re-issue Bankers’ Acceptances and (iii) issue, cancel and re-issue Letters of Credit.

(b) Types of Advances. The Borrower may obtain Advances under each Credit Facility by way of:

(i) Prime Loans;

(ii) USBR Loans;

(iii) LIBOR Loans;

(iv) Bankers’ Acceptances;

(v) Letters of Credit; and

(vi) Overdrafts (under the Swing Line Commitment only).

(c) Several Obligations. No Lender shall be responsible for the Commitments of any other Lender. The failure of a Lender to make available its Pro Rata Share of any Advance in accordance with its obligations under this Agreement shall not release any other Lender from its obligations hereunder. Notwithstanding anything to the contrary in this Agreement, no Lender shall be obligated to make Advances available to the Borrower in excess of its Commitments. The obligation of each Lender to make its Commitments available to the Borrower is a separate obligation between that Lender and the Borrower and such obligation is not the joint or joint and several obligation of any other Lender.

2.2 Purpose of Credit Facility

All Drawdowns shall be used for lawful general corporate purposes of the Borrower.

2.3 Extension of Credit Facility

(a) The Borrower may, at its option, by delivering to the Agent an Extension Request, request the Lenders to extend the Maturity Date for an additional period of one, two or three years; provided that (i) this request cannot be made more than 90 days or less than 60 days before each Renewal Date (commencing November 17, 2010) and (ii) the new Maturity Date cannot extend for more than three years from the applicable Renewal Date.

(b) Promptly after receipt from the Borrower of an executed Extension Request, the Agent shall deliver to each Lender a copy of such request, and each Lender shall, within 30 days after receipt of such request, advise the Agent in writing (i) whether such Lender will agree to extend the Maturity Date, and (ii) if such Lender will agree to extend the Maturity Date, the amount, if any, by which such Lender is prepared to increase its Commitments in the event the Borrower proposes to assign some or all of the Commitments of a Non-Extending Lender (as defined below); provided that if any Lender fails to so advise the Agent within such 30 day period, then such Lender shall be deemed to have advised the Agent that it will not agree to extend the Maturity Date. The Agent shall promptly notify the Borrower if any Lender advises or is deemed to advise that it will not agree to extend the Maturity Date. The Agent shall only extend the Maturity Date upon the agreement of the Majority Lenders and such extension shall apply only to those Lenders which provided their consent to such extension (the “Extending Lenders”). The determination of each Lender whether or not to extend the Maturity Date shall be made by each individual Lender in its sole discretion.

(c) Promptly after all of the Lenders have advised, or are deemed to have advised, the Agent whether or not they will be extending the Maturity Date, the Agent shall either:

(i) deliver to the Borrower (with a copy to each Lender) a written extension signed by the Agent; or

(ii) notify the Borrower that the request for extension has been denied.

If the extension is approved by less than all of the Lenders, then the Agent shall also advise the Borrower of which Lender(s) did not agree to the requested extension (each being a “Non-Extending Lender”), each Non-Extending Lender’s Pro Rata Share of the Loan Indebtedness then outstanding and the amount, if any, by which each Extending Lender is prepared to increase its Commitments in the event the Borrower proposes to assign some or all of the Commitments of a Non-Extending Lender.

(d) The failure of the Agent to deliver a written extension or to notify the Borrower of the denial of the request for extension by the Maturity Date, shall be deemed to be notification by the Agent of the denial of the Borrower’s request.

(e) Upon the delivery to the Borrower of a written extension, the Maturity Date shall be extended for one, two or three years as specified in such written extension.

(f) If an Extension Request is approved but there are Non-Extending Lenders, then:

(i) the Borrower may at any time (subject to Sections 13.2(d), 13.2(e) and 15.1(e)) require any Non-Extending Lender to assign all or any part of its rights, benefits and interests under its Commitments and its Pro Rata Shares of all Loan Indebtedness then outstanding under the Credit Facility (collectively, the “Assigned Interests”) to (A) any Extending Lenders which have agreed to increase their Commitments and purchase Assigned Interests, and (B) to the extent the Assigned Interests are not transferred to Extending Lenders, assignees selected by the Borrower and acceptable to the Agent and the LC Issuer, each acting reasonably; provided that any partial assignment may only occur if the remaining Commitments of such Non-Extending Lender are cancelled in accordance with paragraph (ii) below. Such assignments shall be effective upon execution of Lender Assignment Agreements, upon payment to the relevant Non-Extending Lender (in immediately available funds) by the relevant assignee of an amount equal to its Pro Rata Shares of all Loan Indebtedness being assigned, upon execution of an intercreditor agreement if requested by such Non-Extending Lender pursuant to Section 10.3 (but only if such Non-Extending Lender or its Affiliate is a Swap Lender) and upon payment by the relevant assignee to the Agent (for the Agent’s own account) of the transfer fee contemplated in Section 15.1(b). Upon such assignment and transfer, the Non-Extending Lender shall have no further right, interest or obligation in respect of the Assigned Interests and the assignee thereof shall succeed to the position of such Lender as if the same was an original party hereto in the place and stead of such Non-Extending Lender; and

(ii) to the extent that the Borrower has not caused any Non-Extending Lender to assign all of its rights and interests to an Extending Lender or other assignee as provided in paragraph (i) above, the Borrower may, at any time and notwithstanding any other provision hereof (other than

Sections 13.2(d) and 13.2(e)), repay to such Non-Extending Lender its Pro Rata Shares of all Loan Indebtedness then outstanding under the Credit Facility, without making corresponding repayments to the Extending Lenders, and the Borrower shall cancel such Lender’s Commitments; provided that such cancellation shall require the prior consent of all of the Extending Lenders and shall also require the execution of an intercreditor agreement if requested by such Non-Extending Lender pursuant to Section 10.3 (but only if such Non-Extending Lender or its Affiliate is a Swap Lender). Upon completion of the foregoing, such Non-Extending Lender shall have no further right, interest, benefit or obligation in respect of the Credit Facility and the Total Commitment shall be reduced by the amount of such Lender’s cancelled Commitments.

(g) If all of the Commitments of a Non-Extending Lender are not fully assigned or repaid in accordance with Section 2.3(f), the extension of the Maturity Date shall not apply to such Non-Extending Lender, but such Non-Extending Lender shall continue to be obligated to make its Pro Rata Share of all Syndicated Advances available to the Borrower prior to the Maturity Date determined without regard to the extension agreed to by the Extending Lenders. The Borrower shall repay in full all Outstandings and all other Loan Indebtedness owed to Non-Extending Lenders on the Maturity Date determined without regard to the extension agreed to by the Extending Lenders.

(h) This Section 2.3 shall apply to permit successive extensions to the Maturity Date.

The Borrower shall from time to time, by notice in writing to the Agent (together with reasonable particulars which demonstrate compliance with the positive covenant in Section 8.1(o)), be entitled to designate that either:

(a) an Unrestricted Subsidiary shall become a Restricted Subsidiary; or

2.10 Takeover Notification

(a) If the Borrower wishes to utilize Drawdowns under the Credit Facility to make a take-over bid (as defined under applicable securities laws) which is unsolicited (a “Takeover”), then either:

(i) the Borrower shall provide to the Agent evidence satisfactory to the Agent (acting reasonably) of the agreement of the board of directors or its equivalent of the Person that is the target of the Takeover approving the Takeover; or

(ii) the following steps shall be followed:

(A) at least five Banking Days prior to the delivery of any Notice of Drawdown requesting Drawdowns intended to be utilized for such Takeover, the president, chief financial officer, any vice president, the treasurer or general counsel of the Borrower shall advise a senior official of each Lender and the Agent (designated by each Lender and the Agent at the particular time for such purpose) of the particulars of such Takeover in sufficient detail to enable each Lender to determine whether it has an actual conflict of interest if Drawdowns from such Lender are utilized by the Borrower for such Takeover; and

(B) within three Banking Days of being so advised:

(1) if a Lender shall not have notified the Borrower and the Agent that an actual conflict of interest exists (such determination to be made by each Lender in the exercise of its sole discretion having regard to such considerations as it deems appropriate), such Lender shall be deemed to have no such actual conflict of interest; or

(2) if a Lender has notified the Borrower and the Agent within such period of three Banking Days that such an actual conflict of interest exists, then upon the Borrower and the Agent being so notified, such Lender shall have no obligation to provide Drawdowns to finance such Takeover notwithstanding any other provision of this Agreement to the contrary.

(b) If any notification has been made by a Lender pursuant to Section 2.10(a)(ii)(B)(2), then, except as provided in Section 2.10(c) below, Pro Rata Shares of any Advances made to finance the Takeover in respect of which such notice was given shall be determined without reference to the Commitments of such Lender; and any such notification by a given Lender shall not relieve any other Lender of any of its obligations hereunder, provided that, for certainty, no Lender shall be obligated by this Section to make or provide Advances in excess of its Commitments.

(c) If the conflict of interest giving rise to a notification under Section 2.10(a)(ii)(B)(2) ceases to exist (whether by successful completion of the Takeover or otherwise), then the Lender giving such notification shall, on the next

Rollover or Conversion of or, in the case of a Prime Loan or a USBR Loan, the next Interest Payment Date for, the Advances made to finance the relevant Takeover, purchase, and the other Lenders shall on a rateable basis sell and assign to such Lender, portions of such Advances equal in total to the notifying Lender’s Pro Rata Share thereof without regard to Sections 2.10(a) and 2.10(b).

2.11 Swing Line Advances

(a) Availability. Notwithstanding Sections 2.4, 2.7(c) and 2.8 but otherwise subject to the limits and conditions referred to in this Section 2.11 and the conditions precedent in Article 9, the Borrower may obtain Swing Line Advances from the Swing Line Lender by delivering a Notice of Drawdown to the Swing Line Lender (with a copy to the Agent) not later than 9:00 a.m. (Calgary, Alberta local time) on the proposed Drawdown Date. The making of each Swing Line Advance shall constitute a Drawdown hereunder and shall reduce the availability of the Credit Facility by the U.S. Equivalent of such Swing Line Advances. All interest payments and principal payments made by the Borrower in respect of Swing Line Advances shall be made directly to the Swing Line Lender at the account designated to the Borrower for such purpose and shall be for the sole account of the Swing Line Lender (except as provided otherwise in Section 2.11(f)).

(b) Limitations. Subject to Section 6.1(b), at no time shall:

(i) the U.S. Equivalent of all outstanding Swing Line Advances exceed the Swing Line Commitment;

(ii) the U.S. Equivalent of all outstanding Swing Line Advances plus the U.S. Equivalent of all outstanding Syndicated Advances then owing to the Swing Line Lender in its capacity as a Lender exceed such Lender’s Commitment; and

(iii) the U.S. Equivalent of all outstanding Swing Line Advances plus the U.S. Equivalent of all outstanding Syndicated Advances exceed the Total Commitment.

(c) Repayment of Swing Line Advances. The Borrower may repay Swing Line Advances at any time; provided that it shall deliver a Notice of Rollover/ Conversion/Repayment to the Swing Line Lender (with a copy to the Agent) not later than 11:00 a.m. (Calgary, Alberta local time) on the proposed repayment date. In addition, if the Borrower requests a Syndicated Advance and the Swing Line Lender’s Pro Rata Share of such Syndicated Advance would cause its Pro Rata Share of all Syndicated Advances then outstanding together with all Swing Line Advances then outstanding to exceed its Commitment, then the Borrower shall be required to repay such Swing Line Advances to the extent of such excess on or before the requested date of such requested Syndicated Advance. Swing Line Advances cannot be converted except for Conversions into Syndicated Advances.

(d) Mandatory Conversion of Swing Line Advances. The Swing Line Lender may at any time in its sole and absolute discretion, on behalf of the Borrower (which hereby irrevocably directs and authorizes the Swing Line Lender to make such request on its behalf ), request a Conversion of any Swing Line Advance into a Syndicated Advance (which shall be a Prime Loan or a USBR Loan) in an amount equal to the principal amount of such Swing Line Advance and accrued interest thereon; provided that the provisions of this Section 2.11(d) shall not affect the Borrower’s obligation to repay the Swing Line Advances. Unless the Commitments of the Lenders shall have expired or terminated (in which event the procedures of Section 2.11(e) shall apply), each Lender shall remit its Pro Rata Share of any such Syndicated Advance to the Agent’s Account, and the Agent shall make such funds available to the Swing Line Lender at the Designated Lending Branch of the Swing Line Lender, in each case for same day value on the Banking Day next following the date such notice is given. The proceeds of such Syndicated Advances shall be applied by the Swing Line Lender to the payment in full of the applicable Swing Line Advance.

(e) Purchase of Participations. If the Commitments of all of the Lenders expire or terminate at any time while Swing Line Advances are outstanding, each Lender (other than the Swing Line Lender) shall immediately purchase an undivided participating interest in the outstanding Swing Line Advances in an amount equal to its Pro Rata Share (determined on the date of, and immediately prior to, expiration or termination of the Commitments of the Lenders) of the aggregate principal amount of the outstanding Swing Line Advances by immediately paying to the Swing Line Lender, for same day value, the amount of its participation.

(f) Refund by Swing Line Lender. If a Swing Line Lender receives payment from any Lender in respect of such Lender’s participating interest in a Swing Line Advance and the Swing Line Lender thereafter receives any payment on account thereof from the Borrower, the Swing Line Lender will distribute to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded); provided, however, that in the event that any such payment received by the Swing Line Lender is required to be returned, such Lender will return to the Swing Line Lender any portion thereof previously distributed by the Swing Line Lender to such Lender.

(g) Notice of Default. The Swing Line Lender agrees that it will not make any Swing Line Advances to the Borrower from and after the date on which it receives a written notice from the Borrower, the Agent or any Lender referring to this Agreement and stating that a Default or an Event of Default has occurred and is continuing hereunder until the date on which such Default or Event of Default is no longer continuing. The Swing Line Lender shall be entitled to disregard any notice given by a Lender under this Section 2.11(g) in circumstances where, in the Swing Line Lender’s reasonable determination, no Default or Event of Default has occurred and is continuing. The Agent agrees to provide the Swing Line Lender

with a copy of any notice of Default or Event of Default received by the Agent, promptly after the receipt of same.

(h) Obligations Absolute. For certainty, it is hereby acknowledged and agreed that the Lenders shall be obligated to advance their Pro Rata Shares of the Syndicated Advance contemplated by Section 2.11(d) or complete the purchase contemplated by Section 2.11(e) and to disburse to the Swing Line Lender their Pro Rata Shares of the outstanding Swing Line Advance or purchase price referenced therein irrespective of:

(i) whether a Default or Event of Default is then continuing or whether any other condition precedent in Section 9.2 has been satisfied; and

(ii) in the case of any such Advance, whether or not the Borrower has, in fact, actually requested such Advance (by delivery of a Notice of Rollover/ Conversion/Repayment or otherwise).

2.12 Increase in Total Commitment

The Borrower may, at any time and from time to time, increase the Total Commitment (the “Additional Commitments”) by adding additional Persons as Lenders hereunder or by increasing the Commitments of existing Lenders with (in the latter case) the consent of such Lenders (in their sole discretion), or any combination thereof. The right to increase the Total Commitment by Additional Commitments shall be conditional upon compliance with the following conditions:

(a) no Default or Event of Default shall have occurred and be continuing and the Borrower shall have delivered to the Agent (i) an officer’s certificate confirming the absence of any Default or Event of Default and also confirming (A) its corporate authorization to make such increase (and attaching a copy thereof), (B) the truth and accuracy of its representations and warranties in Section 7.1 and (C) that no consent, approvals or authorizations are required for such increase (except as have been unconditionally obtained and are in full force and effect, unamended), each as at the effective date of such increase and (ii) a satisfactory legal opinion from Borrower’s Counsel confirming items (A) and (C) above and the enforceability of the documentation giving effect to such increase;

(b) after giving effect to any such increase, the Total Commitment shall not exceed U.S.$450,000,000;

(c) if such Person being added as a Lender is not an existing Lender, the Agent, the LC Issuer and the Swing Line Lender shall have consented to any Person becoming a Lender, such consent not to be unreasonably withheld;

(d) the Borrower and the existing Lenders or the Person being added, as the case may be, shall execute and deliver such documentation as may be required by the Agent, acting reasonably, to effect the increase in question (including the partial assignment of Loan Indebtedness or purchase of Commitments from the Lenders

to the extent necessary to ensure that, after giving effect to such increase, each Lender holds its Pro Rata Share of the outstanding Loan Indebtedness) and, if applicable, to novate such new Person as a Lender under the Loan Documents; and

(e) the Agent will prepare and distribute to the Borrower and the Lenders a revised Schedule A which reflects the Additional Commitments.

(b) The face amount of any Bankers’ Acceptance shall be Cdn. or U.S. $100,000, as applicable, or any integral multiple thereof. If the face amount of a Bankers’ Acceptance which would otherwise be accepted by a Lender would not be Cdn. or U.S. $100,000, as applicable, or an integral multiple thereof, such face amount shall be increased or decreased by the Agent in its sole discretion to Cdn. or U.S. $100,000, as applicable, or the nearest integral multiple of that amount, as appropriate; provided that the aggregate face amount of the Bankers’ Acceptances to be accepted by a Lender shall not exceed such Lender’s Commitment in effect on such date.

4.2 Purchase of Bankers’ Acceptances

If any Bankers’ Acceptance (excluding Discount Notes) has not been sold on its issue date, which sale shall be the sole responsibility of the Borrower, the Lender that accepts such

Bankers’ Acceptance may (but shall not be obligated to) purchase such Bankers’ Acceptance for its own account at the purchase price that reflects any BA Discount Rate which may be agreed to by the Borrower and such Lender. The obligation of the Borrower to pay to such Lender the face amount of any Bankers’ Acceptances so purchased by such Lender upon the maturity thereof shall continue in full force and effect notwithstanding such purchase.

4.3 Depository Bills and Notes Act

If and for so long as the power of attorney referred to in Section 4.4(a) is in force with respect to each of the Lenders, it is intended that pursuant to the DBNA, all Bankers’ Acceptances accepted by the Lenders (other than Non-BA Lenders) under this Agreement will be issued in the form of a “depository bill” (as defined in the DBNA) and deposited with a “clearing house” (as defined in the DBNA including, without limitation, CDS Clearing and Depository Services Inc. or its nominee CDS & Co.). In order to give effect to the foregoing, the Agent will, subject to the approval of the Borrower and the Majority Lenders (such approval not to be unreasonably withheld or delayed), establish and notify the Borrower and the Lenders of any additional procedures, consistent with the terms of this Agreement and the DBNA, as are reasonably necessary to accomplish such intention, including:

(a) any instrument held by the Agent for the purposes of Bankers’ Acceptances (excluding Discount Notes) will 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 bill subject to the Depository Bills and Notes Act (Canada)”;

(b) any reference to the authentication of the Bankers’ Acceptance will be removed; and

(c) any reference to the “bearer” will be removed and such Bankers’ Acceptances will not be marked with any words prohibiting negotiation, transfer or assignment of it or of an interest in it.

4.4 Terms of Acceptance by Lenders

(a) Power of Attorney. The Borrower hereby appoints each Lender, acting by any authorized signatory of such Lender, the attorney of the undersigned:

(i) to execute, for and on behalf and in the name of the Borrower as drawer, and to endorse on its behalf, drafts in such Lender’s standard form which constitute depository bills for the purpose of the DBNA (in the case of Lenders other than Non-BA Lenders) and Discount Notes (in the case of Non-BA Lenders);

(ii) to complete the amount, date and maturity date of such Bankers’ Acceptances (or Discount Notes as applicable); and

(iii) to deposit such Bankers’ Acceptances which have been accepted by such Lender with a clearing house (as defined in the DBNA);

provided that such acts in each case are to be undertaken by such Lender strictly in accordance with instructions given to such Lender by the Borrower as provided in this Section 4.4(a). For certainty, signatures of any authorized signatory of such Lender may be mechanically reproduced in facsimile on Bankers’ Acceptances (or Discount Notes as applicable) issued in accordance with Section 4.5 and such facsimile signatures will be binding and effective as if they had been manually executed by such authorized signatory of such Lender. Instructions from the Borrower to such Lender relating to the execution, completion, endorsement, discount and/or delivery by such Lender on behalf of the Borrower of Bankers’ Acceptances (or Discount Notes as applicable) will be communicated by delivery to the Agent of a Notice of Borrowing.

(b) Delivery and Payment

(i) If the Borrower has withdrawn the power of attorney pursuant to Section 4.4(a), the Borrower will pre-sign and deliver to each Lender bankers’ acceptance drafts (or Discount Notes as applicable) in sufficient quantity to meet the Borrower’s requirements for anticipated Advances by way of Bankers’ Acceptances.

(ii) The Borrower waives presentment for payment and any defence to payment of any Bankers’ Acceptances and the Borrower will not claim any days of grace for the payment at maturity of any Bankers’ Acceptances.

(iii) Any amount owing by the Borrower in respect of any Bankers’ Acceptance which is not paid in accordance with the foregoing, will, as and from its maturity date, be deemed to be outstanding hereunder as a Prime Loan (if denominated in Cdn. Dollars) or a USBR Loan (if denominated in U.S. Dollars).

(c) No Liability. The Lenders will not be liable for any damage, loss or improper use of any bankers’ acceptance draft or promissory note endorsed in blank except for any loss arising by reason of a Lender failing to use the same standard of care in the custody of such bankers’ acceptance drafts or promissory notes as each such Lender uses in the custody of its own property of a similar nature.

4.5 Mechanics of Issuance

(a) Upon receipt by the Agent of a Notice of Borrowing from the Borrower requesting a BA Issue, the Agent shall promptly notify the Lenders thereof and advise each Lender of the aggregate face amount of Bankers’ Acceptances to be accepted by such Lender, the date of issue and the BA Period for such BA Issue and BA Stamping Fee in respect of the Bankers’ Acceptances to be accepted by such Lender. The allocation among the Lenders of the face amounts of Bankers’ Acceptances to be accepted by each Lender shall be determined by the Agent on a Pro Rata Basis; provided that, when such allocation cannot be evenly made, such allocation shall be rounded by the Agent in its discretion in accordance with its normal money market practices.

(b) On each Drawdown Date, Rollover Date or Conversion Date involving a BA Issue, the Borrower shall obtain quotations regarding the sale of the Bankers’ Acceptances and provide the details thereof to the Agent prior to 9:00 a.m. (Calgary, Alberta local time) whereupon the Agent shall promptly notify the Lenders of the identity of the purchasers of such Bankers’ Acceptances (excluding Discount Notes), the amounts and denominations being purchased by such purchasers, and settlement instructions in connection therewith, the BA Discount Rates, the BA Discount Proceeds and the BA Stamping Fees applicable to such BA Issue (including each Lender’s share thereof).

(c) On each Drawdown Date, Rollover Date or Conversion Date involving a BA Issue, each Lender shall sign on behalf of the Borrower (if the power of attorney referred to in Section 4.4(a) remains in effect), complete and accept, in accordance with the Notice of Borrowing delivered by the Borrower and advised by the Agent in connection with such issue, its Pro Rata Share (as adjusted pursuant to Sections 4.1(b) and 4.5(a)) of the Bankers’ Acceptances to be issued on such date and each Lender (other than Non-BA Lenders) shall deliver such Bankers’ Acceptances in accordance with the Borrower’s settlement instructions.

(d) On each Drawdown Date involving the issuance of Bankers’ Acceptances, each Lender shall, for same day value on the Drawdown Date, remit the BA Discount Proceeds received (or in the case of Non-BA Lenders, the amount that would have been received if such Lender was not a Non-BA Lender) by such Lender (net of the BA Stamping Fee payable to such Lender pursuant to Section 3.4) to the Agent for the account of the Borrower; and the Agent shall credit such funds to the Borrower’s Accounts for same day value on such date.

(e) In respect of any Rollover of Bankers’ Acceptances, in order to satisfy the continuing liability of the Borrower to a Lender for the face amount of maturing Bankers’ Acceptances accepted by such Lender, such Lender shall receive and retain for its own account the BA Discount Proceeds of new Bankers’ Acceptances issued on such Rollover, and the Borrower shall on the maturity date of the Bankers’ Acceptances being rolled over pay to the Agent for the account of such Lender an amount equal to the difference between the face amount of the maturing Bankers’ Acceptances and the BA Discount Proceeds from the new Bankers’ Acceptances, together with the BA Stamping Fee payable to such Lender in the amount calculated pursuant to Section 3.4.

(f) In respect of any Conversion into Bankers’ Acceptances, in order to satisfy the continuing liability of the Borrower to the Lenders for the amount of the converted Advance, each Lender shall receive and retain for its own account the BA Discount Proceeds of the Bankers’ Acceptances issued upon such Conversion, and the Borrower shall on the Conversion Date pay to the Agent for the account of the Lenders an amount equal to the difference between the principal amount of the converted Advance and the aggregate BA Discount Proceeds from the Bankers’ Acceptances issued on such Conversion, together with the BA Stamping Fee payable to the Lenders in the amount calculated pursuant to Section 3.4.

(g) Each Lender may at any time and from time to time hold, sell, rediscount or otherwise dispose of any or all Bankers’ Acceptances accepted and purchased by it for its own account.

4.6 Escrow Funds

Upon the occurrence of an Event of Default or as otherwise provided herein, the Borrower will forthwith pay to the Agent for deposit into an escrow account maintained by and in the name of the Agent for the benefit of the Lenders, an amount equal to the aggregate face amount of the then outstanding Bankers’ Acceptances (the “Escrow Funds”). The Escrow Funds will be held by the Agent for set-off against future indebtedness owing by the Borrower to the applicable Lenders in respect of such Bankers’ Acceptances and prior thereto will bear interest at the rate declared by the Agent 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 applicable Bankers’ Acceptances. If such Event of Default is either waived or cured in compliance with the terms of this Agreement, then the remaining Escrow Funds, if any, together with any accrued interest to the date of release, will be released to the Borrower.

4.7 BA Equivalent Loans

Notwithstanding the other provisions of this Article 4, a Non-BA Lender shall, in lieu of accepting and purchasing Bankers’ Acceptances, make a BA Equivalent Loan. The amount of each BA Equivalent Loan shall be equal to the BA Discount Proceeds which would be realized from a hypothetical sale of those Bankers’ Acceptances to such Non-BA Lender which such Lender would otherwise be required to accept and purchase as part of such a BA Issue. To determine the amount of such BA Discount Proceeds, the hypothetical sale shall be deemed to take place at the BA Discount Rate and using the BA Period for such BA Issue. Any BA Equivalent Loan shall be made on the relevant Drawdown Date, Rollover Date or Conversion Date, as the case may be, and shall remain outstanding for the term of the relevant Drawdown or Rollover of, or Conversion into, Bankers’ Acceptances issued concurrently therewith. Concurrently with the making of a BA Equivalent Loan, a Non-BA Lender shall be entitled to deduct therefrom an amount equal to the BA Stamping Fee which such Lender would otherwise be entitled to receive pursuant to Section 3.4 as part of such BA Issue if such Lender was accepting Bankers’ Acceptances, based on the amount payable on the maturity date of such BA Equivalent Loan. The BA Equivalent Loan shall accrue interest at a rate per annum equal to the BA Discount Rate for the term of such BA Equivalent Loan. Upon the maturity date for such Bankers’ Acceptances, the Borrower shall pay to each Non-BA Lender, in satisfaction of the face amount of its BA Equivalent Loan plus interest accrued thereon, an amount equal to the face amount of the Discount Notes issued by the Borrower in respect of its BA Equivalent Loans, failing which such amount shall be converted to a Prime Loan (if denominated in Cdn. Dollars) or a USBR Loan (if denominated in U.S. Dollars). As set out in the definition of “Bankers Acceptances”, that term includes Discount Notes and all provisions of this Agreement applicable to Bankers’ Acceptances shall apply equally to Discount Notes evidencing BA Equivalent Loans with such changes as may in the context be necessary. All references in this Agreement to “Advances” and “BA Issue” shall, unless otherwise expressly provided herein or unless the context otherwise requires, be deemed to include BA Equivalent Loans made by a Non-BA Lender as part of a Drawdown or Rollover of, or Conversion into, Bankers’ Acceptances.

ARTICLE 5
LETTERS OF CREDIT

5.1 Availability of Letters of Credit

(a) Each Letter of Credit shall be made available by the LC Issuer on behalf of all Lenders, and each Letter of Credit (including all applications therefor and all documents and instruments required to be presented thereunder) shall be satisfactory in form and substance to the LC Issuer. No Letter of Credit shall be issued (or shall be renewable at the option of the beneficiary thereunder) for a term which (i) expires beyond the Maturity Date, or (ii) exceeds 1 year, or (iii) requires payment in any currency not acceptable to the LC Issuer and the Agent, each acting reasonably.

(b) The maximum amount of all outstanding Letters of Credit at any time shall not exceed U.S. $75,000,000 or an amount in any other currency that has a U.S. Equivalent of U.S. $75,000,000. For the purpose of calculating such maximum amount and the Outstandings and for any other relevant provision of this Agreement, the principal amount of any LC Issue shall be the maximum amount in U.S. Dollars (for which purpose any amount payable in any other currency shall be deemed to be the U.S. Equivalent thereof) which the LC Issuer may in all circumstances be required to pay pursuant to the terms thereof. In addition, for the purpose of calculating the Outstandings owing at any time to any Lender (including the LC Issuer), each Letter of Credit shall be deemed to have been made available on a Pro Rata Basis by the Lenders.

5.2 Reimbursement Obligations

(a) The Borrower shall pay to the LC Issuer sufficient funds in the currency of the relevant Letter of Credit, either immediately on demand by the LC Issuer, to reimburse the LC Issuer for any payment made by it pursuant to such Letter of Credit, or at the option of the LC Issuer by prior written notice to the Borrower, on or prior to the date on which any payment is to be made by the LC Issuer pursuant to such Letter of Credit, to fund such payment by the LC Issuer. If the Borrower does not make any payment required by the preceding sentence, the LC Issuer may (but shall not be obliged to), without receipt of a Notice of Drawdown and irrespective of whether any other applicable conditions precedent specified herein have been satisfied, and without waiver of the Default constituted by the Borrower’s failure to make such required payment, make a Prime Loan where the currency of such required payment is Cdn. Dollars or a USBR Loan where the currency of such required payment is in any currency other than Cdn. Dollars, to the Borrower in the aggregate amount of such required payment, and shall forthwith give notice thereof to the Borrower and the Agent. For the purposes of determining the principal amount of such USBR Loan where the currency of the required payment is not U.S. Dollars, the required payment shall be converted into U.S. Dollars on the basis of the actual exchange rate obtained by the LC Issuer to purchase the required amount of such other currency on the

date of the required payment. The Borrower agrees to accept each such Advance and hereby irrevocably authorizes and directs the LC Issuer to apply the proceeds thereof in payment of the liability of the Borrower with respect to such required payment.

(b) Each of the Lenders, other than the LC Issuer, agrees that it shall purchase from the LC Issuer, and the LC Issuer shall sell to such Lenders, for cash, at par, without representation or warranty from or recourse to the LC Issuer, (and irrespective of whether any condition precedent to an Advance has been met, whether any Default or Event of Default has occurred or is continuing or whether any acceleration or any enforcement action (including any termination of the Commitments) has occurred or commenced under the Loan Documents or otherwise or whether the Maturity Date has lapsed) on a Pro Rata Basis, an undivided interest in any Advance made by the LC Issuer pursuant to Section 5.2(a), immediately upon such Advance being made. The LC Issuer, upon consultation with the purchasing Lenders, shall have the power to settle any documentation required to evidence any such purchase and, if deemed advisable by the LC Issuer, to execute any document as attorney for any Lender in order to complete any such purchase. The Borrower and the Lenders acknowledge that the foregoing arrangements are to be settled by the Lenders among themselves, and the Borrower expressly consents to the foregoing arrangements among such Lenders. Notwithstanding that any Lender may assign its rights and obligations hereunder, the obligations in this Section 5.2(b) shall continue as obligations of the Persons who were Lenders at the time each such Letter of Credit was issued, unless the LC Issuer specifically releases such Lender from such obligations by executing the applicable Lender Assignment Agreement.

(c) If a domestic or foreign court issues any judgment or order extending the liability of the LC Issuer to make payment under such Letter of Credit beyond the expiry date specified therein, the Borrower shall forthwith upon demand by the LC Issuer pay to the LC Issuer, funds in the currency of such Letter of Credit and in the amount of the Advance constituted by such Letter of Credit. Such funds (together with interest thereon) shall be held by the LC Issuer for payment of the liability of the Borrower pursuant to Section 5.2(a) or otherwise in respect of such Letter of Credit so long as the aforementioned judgment or order remains in force and the LC Issuer has or may in any circumstance have any liability under such Letter of Credit, and shall bear interest for such terms as are selected from time to time by the LC Issuer at the wholesale money market rate of the LC Issuer for deposits of similar currency, amounts and maturities. Any balance of such funds and interest remaining at such time as the LC Issuer does not have and may never have any liability under such Letter of Credit shall nevertheless continue to be held by the LC Issuer, if and so long as any Default or Event of Default is continuing, as security for the remaining liabilities of the Borrower under the Loan Documents.

5.3 General Provisions Regarding Letters of Credit

(a) The Borrower agrees that neither the LC Issuer nor its officers, directors or correspondents shall assume liability for, or be responsible for:

(i) the use which may be made of any Letter of Credit; or any acts or omissions of the beneficiary of any Letter of Credit including the application of any payment made to such beneficiary;

(ii) the validity, correctness, genuineness or legal effect of any document or instrument relating to any Letter of Credit, even if such document or instrument should in fact prove to be in any respect invalid, insufficient, inaccurate, fraudulent or forged;

(iii) payment by the LC Issuer of any draft which does not comply with the terms of any Letter of Credit, unless such payment results from the gross negligence or wilful misconduct of the LC Issuer;

(iv) the failure of any document or instrument to bear any reference or adequate reference to any Letter of Credit;

(v) any failure of the beneficiary of any Letter of Credit to meet the obligations of such beneficiary to the Borrower or any other Person;

(vi) any errors, inaccuracies, omissions, interruptions or delays in transmission or delivery of any messages, directions or correspondence by mail, facsimile or otherwise received by the LC Issuer, whether or not they are in cipher;

(vii) any inaccuracies in the translation of any messages, directions or correspondence or for errors in the interpretation of any technical terms, other than by reason of the gross negligence or wilful misconduct of the LC Issuer; or

(viii) any failure by LC Issuer to make payment under any Letter of Credit as a result of any law, control or restriction rightfully or wrongfully exercised or imposed by any domestic or foreign Governmental Authority or as a result of any other cause beyond the reasonable control of the LC Issuer or its officers, directors or correspondents.

(b) The obligations of the Borrower under this Article 5 with respect to any Letter of Credit shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of the applicable Loan Documents under all circumstances including, without limitation:

(i) any matter referred to in Section 5.3(a);

(ii) any invalidity of any obligation secured by any Letter of Credit;

(iii) any incapacity, disability or lack or limitation of status or of power of any Borrower or the beneficiary of any Letter of Credit;

(iv) any lack of validity or enforceability of any Letter of Credit; or

(v) the existence of any claim, set-off, defence or other right which either Borrower may have at any time against the LC Issuer, any other Lender, the Agent, the beneficiary of any Letter of Credit or any other Person; or any breach of contract or other dispute between the Borrower and the LC Issuer, any other Lender, the Agent, the beneficiary of any Letter of Credit or any other Person.

(c) The LC Issuer may accept as complying with the terms of any Letter of Credit any document or instrument required by such Letter of Credit to be completed, signed, presented or delivered by or on behalf of any beneficiary thereunder which has been completed, signed, presented or delivered by a receiver, trustee in bankruptcy, assignee for the benefit of creditors, secured party or other like Person believed in good faith by the LC Issuer to be lawfully entitled to the property of such beneficiary, and the LC Issuer may make payments under such Letter of Credit to such Person. The provisions of this Section 5.3(c) are for the sole benefit of the LC Issuer and the Lenders, and may not be relied on by any other Person.

(d) Each Letter of Credit, except as specifically provided therein, and subject to any provision hereof to the contrary, shall be subject to the Uniform Customs and Practice for Documentary Credits of the International Chamber of Commerce current at the time of issuance of such Letter of Credit.

(e) In the case of any variance between any document or instrument required by a Letter of Credit and any document or instrument presented by or on behalf of any beneficiary thereunder, the Borrower shall be deemed to have ratified and confirmed the LC Issuer’s acceptance of the document or instrument so presented as complying with such Letter of Credit and to have waived any right which the Borrower might otherwise have had to object to variance from the document or instrument required by such Letter of Credit unless within 30 days of receipt thereof the Borrower shall have advised the LC Issuer in writing of any variance to which it objects.

(a) the Debenture;

(b) the Deposit Instrument;

(d) the Subordination Agreements dated April 2, 2003 from each of the Restricted Subsidiaries.

In respect of the Security:

(i) over certain of the Fixed Charge Assets, the Agent agrees to provide, and is hereby authorized by the Lenders and the Swap Lenders to provide, the acknowledgments contemplated by Section 6.05 of the Plant Co-Owners Agreement dated as of July 11, 1997 between NOVA Chemicals Corporation (as successor to NOVA Chemicals Ltd.) and Dow Chemical Canada Inc. (as successor to Union Carbide Canada Inc.) and by Section 9.5 of the Infrastructure Co-Owners Agreement dated as of July 11, 1997 between NOVA Chemicals Corporation (as successor to NOVA Chemicals Ltd.) and Dow Chemical Canada Inc. (as successor to Union Carbide Canada Inc.); and

(ii) over personal property which is the subject of Permitted Securitization Programs, Permitted ABL Facilities and Permitted Non-Recourse Debt, the Agent agrees to provide, and is hereby authorized by the Lenders and the Swap Lenders to provide the following:

(A) in the case of a Permitted Securitization Program or Permitted Non-Recourse Debt, a discharge and release in respect of the rights of the Agent and the Lenders under the Security Documents in respect of such personal property; and

(B) in the case of a Permitted ABL Facility, a subordination agreement in respect of the rights of the Agent and the Lenders under the Security Documents in respect of such personal property.

10.2 Registration

(a) The Borrower shall, at its expense, register, file or record the Security in all offices where such registration, filing or recording is necessary or of advantage to the creation, perfection and preserving of the security applicable to it. The Borrower shall amend and renew such registrations, filings and recordings from time to time as and when required to keep them in full force and effect or to preserve the Lien established by any prior registration, filing or recording thereof. To facilitate such ongoing perfection of the Security, the Borrower shall promptly notify the Agent of (a) any change in the location of its chief executive office from Calgary or Pittsburgh or (b) any acquisition by it of any material property or assets located outside of the Provinces of Alberta or Ontario.

(b) The Borrower shall not be required to register, file or record the Security at any land titles office or registry against any specific real property interests owned by the Borrower (other than the Fixed Charge Assets) unless directed to do so by (i) the Majority Lenders at any time when no Event of Default exists, (ii) any Lender at any time when an Event of Default exists, or (iii) any Swap Lender when an “Event of Default” exists under and as defined in any Secured Hedging Agreement with such Swap Lender.

(c) The Agent shall have the right to make, at the expense of the Borrower, all such registrations, filings or recordings as are required to be made by the Borrower pursuant to this Section 10.2.

(d) If the Agent, any Lender or any Swap Lender registers, files or records the Security at any land titles office or registry against any specific real property interests owned by the Borrower (other than the Fixed Charge Assets), such Person shall promptly notify the Agent and the Borrower, as applicable.

10.3 Sharing Security

The Borrower and the Lenders agree and acknowledge that the Security is being held by the Agent to secure firstly the Loan Indebtedness and the Senior Secured Swap Obligations on a senior basis (and on a pari passu basis within these senior obligations) and secondly any Subordinate Secured Swap Obligations on a subordinate basis (and on a pari passu basis within these subordinate obligations), as more particularly contemplated below. For purposes of the above sentence, pari passu basis means:

(a) with respect to the Lenders, proportional between (i) the Loan Indebtedness and (ii) the aggregate of the Loan Indebtedness plus the Senior Secured Swap Obligations; and

(b) with respect to the Swap Lenders, proportional between (i) the Senior Secured Swap Obligations and (ii) the aggregate of the Loan Indebtedness plus the Senior Secured Swap Obligations.

The Swap Lenders, as among themselves, will share their pro rata allocation of the Security, as determined in paragraph (b) above in the case of Senior Secured Swap Obligations, based on a pro rata allocation of the aggregate outstanding Senior Secured Swap Obligations owing to each Swap Lender.

The Swap Lenders, as among themselves, will share their subordinate allocation of the Security, as determined in paragraph (c) below in the case of Subordinate Secured Swap Obligations, on a pari passu basis based upon a pro rata allocation of the outstanding Secured Swap Obligations (other than the Huntsman Preferred Stock Obligations) owing to each Swap Lender.

If requested by any of the Agent, the Majority Lenders or any Swap Lender, then each of the Agent and the Swap Lenders will enter into such further intercreditor agreements and assurances as may be reasonably requested to further evidence the sharing provisions of this Section 10.3. In addition to the pari passu sharing provisions referred to above, such further agreements shall incorporate the following principles:

(a) no Swap Lender may enforce the Security (without the Lenders) unless the Borrower defaults in paying any Secured Swap Obligations then due and owing to such Swap Lender in excess of the U.S. Equivalent of U.S. $7,500,000 and such default continues for at least 30 days; provided that any such Secured Swap Obligations not paid by the Borrower by the end of such 30 day period may, at the

option of the Lenders and to the extent of any undrawn availability under the Total Commitment, be paid by the Lenders and shall be deemed to constitute a Prime Loan (if denominated in Cdn. Dollars) or a USBR Loan (if denominated in any currency other than Cdn. Dollars);

(b) after the Lenders or any Swap Lender(s) elect to enforce the Security, any decision or determination which is required to be made by the enforcing secured parties regarding the conduct of such enforcement shall be determined by the enforcing Lenders (if the Loan Indebtedness exceeds the Senior Secured Swap Obligations of the enforcing Swap Lenders) or by the enforcing Swap Lender(s) (if the Senior Secured Swap Obligations of the enforcing Swap Lender(s) exceeds the Loan Indebtedness or if and for so long as the Lenders have not elected to enforce the Security); and

(c) no Swap Lender may receive any proceeds of realization from the Security in respect of the Subordinate Secured Swap Obligations until after the Loan Indebtedness and the Senior Secured Swap Obligations have been repaid in full.

The above principles are intended to apply at all times (whether before or after the execution of any intercreditor agreement) but are not intended to apply to any enforcement of the Swap Guarantee on an unsecured basis.

10.4 Form and Amount of Security

If the Agent, acting reasonably, determines at any time and from time to time that the form and nature of the then existing Security is deficient in any way or does not fully provide the Agent and the Lenders and the Swap Lenders with the Security and priority to which each is entitled hereunder, the Borrower will forthwith execute and deliver or cause to be executed and delivered to the Agent, at the Borrower’s expense, such amendments to the Security or provide such new security as the Agent may reasonably request. Without limiting the foregoing, if any Compliance Certificate delivered by the Borrower discloses that the aggregate of the Total Commitment plus the mark to market position of all Secured Swap Obligations (and for the purposes hereof the mark to market position of the Huntsman Preferred Stock Obligations shall be deemed to be U.S. $75,000,000 or such lesser amount as may be secured by the Security as confirmed to the satisfaction of the Majority Lenders acting reasonably) exceeds U.S. $600,000,000, then the Borrower will forthwith either (a) execute and deliver a supplemental debenture which increases the maximum principal amount of the Debenture by such amount as may be required to ensure that such maximum principal amount exceeds such aggregate secured obligations by at least U.S. $50,000,000 and shall ensure that such supplemental debenture ranks as a first ranking security interest against the Fixed Charge Assets or (b) provide such other security as may be satisfactory to the Majority Lenders acting reasonably.

The forms of Security shall have been or be prepared based upon the Laws of Canada and Alberta applicable thereto in effect at the date hereof. The Agent shall have the right to require that:

(a) any such Security be amended to reflect any changes in such Laws, whether arising as a result of statutory amendments, court decisions or otherwise, in order to confer upon the Agent the Security intended to be created thereby, and

(b) the Borrower execute and deliver to the Agent such other and further debentures, mortgages, trust deeds, assignments and security agreements as may be reasonably required to ensure the Agent, the Lenders and the Swap Lenders have and hold, subject to Permitted Liens, an effective floating charge or security interest over all of the property and assets of the Borrower (other than the Fixed Charge Assets) and a first priority fixed charge over all of the Fixed Charge Assets.

10.5 After-Acquired Property

All property acquired by or on behalf of the Borrower after the date of execution of the Security (hereinafter collectively referred to as “After-Acquired Property”), will be subject to the charges and security interests of the Debenture, without any further conveyance, mortgage, pledge, charge, assignment or other act on the part of the Borrower. Without limiting the effect of the preceding sentence, but subject to Section 10.2, the Borrower will from time to time execute and deliver, or cause to be executed and delivered, and the Agent will register, all at the Borrower’s expense, such instruments supplemental to the Security, in form and substance satisfactory to the Agent, acting reasonably, as may be necessary or desirable to ensure that the Security as amended and supplemented constitutes in favour of the Agent, the Lenders and the Swap Lenders an effective floating charge or security interest over such After-Acquired Property as required hereunder.

10.6 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 Lenders or the Agent under any security, instruments or agreements held by it or at Law or in equity.

10.7 Dealing with Security

The Agent, with the consent of all of the Lenders, may grant extensions of time or other indulgences, take and give up securities (including, without limitation, the Security or any part or parts thereof), accept compositions, grant releases and discharges and otherwise deal with the Borrower and other Parties and with security (including without limitation, the Security and each part thereof) as the Agent may see fit, and may, subject to Section 10.3, apply all amounts received from the Borrower or others or from securities (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 way limiting the liability of the Borrower under this Agreement or under any of the Security or any other collateral security.

10.8 Effectiveness

The Security shall be effective, and the undertakings as to the Security herein or in any other Loan Document shall be continuing, whether any Loan Indebtedness is 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 or before or after or upon the date of execution of any amendments to this Agreement.

10.9 Release and Discharge of Security

The Borrower shall not be discharged from the Security or any part thereof except by a written release and discharge signed by the Agent with the prior written consent of all Lenders and all of the Swap Lenders. If all of the Loan Indebtedness and the Secured Swap Obligations have been repaid, paid, satisfied and discharged, as the case may be, in full and the Credit Facility has been fully cancelled, 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.

10.10 Transfer of Security

If TD, in its capacity as Agent, or any successor thereto, in its capacity as Agent (the “Departing Agent”) ceases to be the Agent, the Departing Agent shall transfer and assign all of the Security to the replacement agent or, if the Credit Facility has been repaid and cancelled, to the Swap Lenders.

(f) Winding-Up.

filing of any petition under any such law or to the appointment of a receiver, or other person with like powers, over all, or substantially all, of the property of the Borrower or such Restricted Subsidiary, or (iv) the Borrower or any Restricted Subsidiary makes a general assignment for the benefit of creditors, or becomes unable to pay its debts generally as they become due, or (v) the Borrower or any Restricted Subsidiary takes any corporate action in furtherance of any of the aforesaid purposes.

(m) Cross Default to Specified Other Debt. After all applicable grace or cure periods have expired, any default, event of default or similar condition or event (however described) in respect of the Borrower or any Restricted Subsidiary

occurs or exists under (1) any bilateral credit facility with any Lender or its Affiliate or (2) any Pari Passu Debt in respect of obligations of the Borrower or any Restricted Subsidiary aggregating in excess of U.S.$25,000,000 (or the U.S. Equivalent thereof in Cdn. Dollars in any other currency); provided that such dollar threshold shall not apply if the holder of such Pari Passu Debt commences proceedings to enforce its security against the Borrower or any Restricted Subsidiary.

11.2 Effect of Events of Default

If an Event of Default occurs and is continuing, the Agent with the approval of the Lenders may, by notice in writing to the Borrower, cancel the availability of all or any part of the Credit Facility and/or declare all or any part of the Outstandings, together with all accrued and unpaid interest thereon and all other Loan Indebtedness, to be immediately due and payable, whereupon:

(a) all such amounts shall become immediately due and payable, without protest, presentment, demand or further notice of any kind, all of which are expressly waived by the Borrower and the Borrower hereby unconditionally promises and agrees to immediately pay such amounts to the Agent;

(b) such notice shall constitute due demand for payment under any notes issued pursuant to the Loan Documents;

(c) a demand for payment of all such amounts may be given to any Restricted Subsidiary under any Restricted Subsidiary Guarantee;

(d) at the option of the Lenders, the Borrower shall convert any LIBOR Loan in U.S. Dollars into a USBR Loan, notwithstanding that such Conversion may cause the Borrower to incur liability pursuant to Section 13.2;

(e) at the option of the Lenders, the Borrower shall forthwith pay funds in an amount sufficient to pay the aggregate face amount of all outstanding Bankers’ Acceptances into a cash collateral account with the Agent and any amount not so paid by the Borrower may, at the option of the Lenders and without notice to the Borrower, be paid by the Lenders into an interest-bearing cash collateral account and shall be deemed to constitute a Prime Loan (if denominated in Cdn. Dollars) or a USBR Loan (if denominated in U.S. Dollars);

(f) at the option of the Lenders, the Borrower shall forthwith pay funds in an amount sufficient to pay the aggregate stated maximum face amount of all outstanding Letters of Credit into a cash collateral account with the Agent and any amount not so paid by the Borrower may, at the option of the Lenders and without notice to the Borrower, be paid by the Lenders into an interest-bearing cash collateral account and shall be deemed to constitute a Prime Loan (if denominated in Cdn. Dollars) or a USBR Loan (if denominated in any currency other than Cdn. Dollars); and

(g) the Agent on behalf of the Lenders shall be entitled to exercise all rights and remedies available to it under any of the Loan Documents, at Law.

11.3 Right of Set-Off

Upon the occurrence and during the continuation of an Event of Default, each Lender is hereby authorized at any time and from time to time thereafter, without notice to the Borrower (any such notice being expressly waived by the Borrower) and to the fullest extent permitted by law, to set-off and apply any and all deposits (whether general or special, time or demand, provisional or final, matured or unmatured) at any time held and any and all other indebtedness at any time owing, by such Lender to or for the credit or the account of the Borrower against any or all of the Loan Indebtedness. Such Lender agrees to promptly notify the Borrower and the Agent after any such set-off and application and to provide particulars of such set-off and application; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. This set-off may occur notwithstanding that such deposits or other indebtedness are expressed in different currencies and such Lender is hereby authorized to effect any necessary currency conversions at the Noon Rate.

ARTICLE 12
INCREASED COSTS

12.1 Increased Costs Due to Changes in Law

(a) If, after the Effective Date, due to either:

(i) the introduction of, or any change in, or in the interpretation of, any Law, resulting in the imposition or increase of reserve, deposit or similar requirements by any court, central bank or other Governmental Authority charged with the administration thereof; or

(ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether having the force of Law or not) which a Lender, acting reasonably and in good faith, determines that it is required to comply with,

there shall be any increase in the cost to such Lender of agreeing to make available or making, funding or maintaining any Advance, or any reduction in the effective return to such Lender thereunder (other than a reduction resulting from a higher rate of income taxes or other special tax relating to such Lender’s income in general), then, subject to paragraph (b) below, the Borrower shall, within 10 days after being notified by such Lender of such event, pay to such Lender quarterly in arrears, that amount (the “Additional Compensation”) which such Lender, acting reasonably, determines shall compensate it, after taking into account all applicable Taxes, for any such increased costs or reduced returns incurred or suffered by such Lender.

(b) If Additional Compensation is payable, the Borrower shall have the option to prepay or convert to another form of Advance any amount of the Credit Facility

affected thereby, subject to compliance with the applicable conversion and repayment provisions set out herein. If the Additional Compensation relates to outstanding Bankers’ Acceptances or Letters of Credit, such Lender may require the Borrower to deposit in an interest bearing account with such Lender (with interest to accrue for the benefit of the Borrower) such amount as may be necessary to fully satisfy the contingent obligations of such Lender for all outstanding Bankers’ Acceptances or Letters of Credit, as applicable, in accordance with the arrangements set out in Section 4.6 (excepting out all references to an Event of Default).

12.2 Illegality

Notwithstanding anything to the contrary herein contained, if on any date a Lender determines in good faith, which determination shall be conclusive and binding on the Parties, that its ability to maintain or continue to offer any type(s) of Advances under the Credit Facility has become unlawful or impossible because:

(a) of any change in applicable Laws, or in the interpretation or administration thereof by any Governmental Authority having jurisdiction in the matter; or

(b) the imposition of any condition, restriction or limitation upon such Lender which is outside of its control,

then such Lender shall give prompt written notice thereof to the Borrower and the Agent, and the Borrower shall forthwith (or at the end of such period as is permitted under the applicable Law) repay to such Lender 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 Advance, including any expenses resulting from the termination of any LIBOR Period relating thereto in accordance with Section 13.2. If the principal amount affected thereby relates to outstanding Bankers’ Acceptances, such Lender may require the Borrower to deposit in an interest bearing account with such Lender (with interest to accrue for the benefit of the Borrower) such amount as may be necessary to fully satisfy the contingent obligations of such Lender for all outstanding Bankers’ Acceptances and Letters of Credit in accordance with the arrangements set out in Section 4.6 (excepting out all references to an Event of Default). The Borrower may utilize other forms of Advances 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 type of Advance upon complying with any other applicable requirements in this Agreement.

12.3 Market Disruption Respecting LIBOR Loans

Notwithstanding anything to the contrary herein contained, if at any time subsequent to the giving of a Notice of Borrowing to the Agent by the Borrower with regard to any requested LIBOR Loan:

(a) the Agent (acting reasonably) determines that by reason of circumstances affecting the London Interbank Eurodollar Market, adequate and fair means do not exist for ascertaining the rate of interest with respect to, or deposits are not available in sufficient amounts in the ordinary course of business to fund, a requested LIBOR Loan during the ensuing LIBOR Period selected;

(b) the Agent (acting reasonably) determines that the making or continuing of the requested LIBOR Loan by the Lenders has been made impracticable by the occurrence of an event which materially adversely affects the London Interbank Eurodollar Market generally; or

(c) the Agent is advised by Lenders holding at least 25% of the Total Commitment by written notice (each, a “ LIBOR Suspension Notice”), such notice received by the Agent no later than 12:00 noon (Calgary, Alberta local time) on the third Banking Day prior to the date of the requested Drawdown, Rollover or Conversion, as the case may be, that such Lenders (acting reasonably) have determined that the LIBOR to be determined in accordance with this Agreement will not or does not represent the effective cost to such Lenders of U.S. Dollar deposits in such market for the relevant LIBOR Period,

then the Agent shall give notice thereof to the Lenders and the Borrower as soon as possible after such determination or receipt of such LIBOR Suspension Notice, as the case may be, and the Borrower shall, within one Banking Day after receipt of such notice and in replacement of the Notice of Borrowing previously given by the Borrower, give the Agent a new Notice of Borrowing which specifies any other Drawdown or the Conversion of the relevant LIBOR Loan on the last day of the applicable LIBOR Period into any other Advance which would not be affected by the notice from the Agent pursuant to this Section 12.3.

In the event the Borrower fails to give, if applicable, a valid replacement Notice of Borrowing with respect to the maturing LIBOR Loans which were the subject of a Notice of Borrowing, such maturing LIBOR Loans shall be converted on the last day of the applicable LIBOR Period into USBR Loans as if a valid replacement Notice of Borrowing had been given to the Agent by the Borrower pursuant to the provisions hereof. In the event the Borrower fails to give, if applicable, a valid replacement Notice of Drawdown with respect to a Drawdown originally requested by way of a LIBOR Loan, then the Borrower shall be deemed to have requested a Drawdown by way of a USBR Loan in the amount specified in the original Notice of Borrowing and, on the originally requested Drawdown Date, the Lenders (subject to the other provisions hereof) shall make available the requested amount by way of a USBR Loan.

12.4 Market Disruption Respecting Bankers’ Acceptances

Notwithstanding anything to the contrary herein contained, if:

(a) the Agent (acting reasonably) makes a determination, which determination shall be conclusive and binding upon the Borrower, and notifies the Borrower, that there no longer exists an active market for bankers’ acceptances accepted by the Lenders; or

(b) the Agent is advised by Lenders holding at least 25% of the Total Commitment by written notice (each, a “BA Suspension Notice”) that such Lenders (acting reasonably) have determined that the BA Discount Rate will not or does not accurately reflect the discount rate which would be applicable to a sale of Bankers’ Acceptances accepted by such Lenders in the market for the applicable term;

then:

(c) the right of the Borrower to request Bankers’ Acceptances or BA Equivalent Loans from any Lender shall be suspended until the Agent determines that the circumstances causing such suspension no longer exist, and so notifies the Borrower and the Lenders;

(d) any outstanding Notice of Drawdown requesting the issuance of Bankers’ Acceptances or BA Equivalent Loans shall be deemed to be a Notice of Drawdown requesting a Prime Loan in the amount specified in the original Notice of Drawdown;

(e) any outstanding Notice of Borrowing requesting a Conversion of a USBR Loan or LIBOR Loan into Bankers’ Acceptances or BA Equivalent Loans shall be deemed to be a Notice of Borrowing requesting a Conversion of such Advance into a Prime Loan; and

(f) any outstanding Notice of Borrowing requesting a Rollover of Bankers’ Acceptances or BA Equivalent Loans shall be deemed to be a Conversion Notice of Borrowing requesting a Conversion of such Advance into a Prime Loan.

The Agent shall promptly notify the Borrower and the Lenders of any suspension of the Borrower’s right to request the Bankers’ Acceptances or BA Equivalent Advances and of any termination of any such suspension. A BA Suspension Notice shall be effective upon receipt of the same by the Agent if received prior to 12:00 noon (Calgary, Alberta local time) on a Banking Day and if not, then on the next following Banking Day, except in connection with a Notice of Borrowing previously received by the Agent, in which case the applicable BA Suspension Notice shall only be effective with respect to such previously received Notice of Borrowing if received by the Agent prior to 12:00 noon (Calgary, Alberta local time) two Banking Days prior to the proposed Drawdown Date, Conversion Date or Rollover Date (as applicable) applicable to such previously received Notice of Borrowing.

12.5 Application of Sections 12.1, 12.2, 12.3 and 12.4

If a Lender exercises its rights under this Article 12, then concurrently with a written notice from such Lender to the Borrower requiring compliance with the applicable provision, such Lender shall provide the Borrower with a certificate in reasonable detail outlining the particulars giving rise to such notice, confirming that its actions are consistent with actions concurrently taken by such Lender with respect to similar type provisions affecting other borrowers of such Lender in comparable circumstances and, in the case of Section 12.1, certifying (with reasonable supporting detail) the increased costs, if any, payable by the Borrower hereunder, which shall be prima facie proof thereof and binding on the Parties.

ARTICLE 13
COSTS, EXPENSES AND INDEMNIFICATION

13.1 Costs and Expenses

The Borrower shall, promptly upon demand by the Agent, pay (a) all reasonable costs and expenses of the Agent in connection with the preparation, execution, delivery, registration, syndication and ongoing administration of this Agreement and all other Loan Documents, and (b) all reasonable costs and expenses of the Agent and the Lenders in connection with the amendment and enforcement of, and the waiver or preservation of any of the Agent’s and the Lenders’ rights under this Agreement and all other Loan Documents (including in either case the reasonable fees and expenses of Lenders’ Counsel on a solicitor and his own client basis). The Agent or the Lenders, as the case may be, shall within a reasonable time give notice to the Borrower of any amounts payable by the Borrower under this Section 13.1 and such amounts shall be paid within 30 days thereafter. Any amounts not so paid will bear interest at the rate set out in Section 3.9 from the date such cost or expense should have been paid until the Agent or the Lenders have been paid in full.

13.2 General Indemnity

In addition to any liability of the Borrower to any Lender or the Agent 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 losses, claims, costs, damages or liabilities (including, without limitation, any expense or cost incurred in the liquidation and re-deployment of funds acquired to fund or maintain any portion of an Advance and reasonable out-of-pocket expenses and reasonable legal fees on a solicitor and his own client basis) incurred by the same as a result of or in connection with the Credit Facility or the Loan Documents, including, without limitation, as a result of or in connection with:

(a) 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 Advance 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;

(b) subject to permitted or deemed Rollovers and Conversions, the Borrower’s failure to provide for the payment to the Agent for the account of the Lenders of the full principal amount of each Bankers’ Acceptance on its maturity date;

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

(d) the repayment, prepayment or mandatory assignment of a LIBOR Loan otherwise than on the last day of its LIBOR Period;

(e) the prepayment or mandatory assignment of any outstanding Bankers’ Acceptance before the maturity date of such Bankers’ Acceptance;

(f) the Borrower’s failure to give any notice required to be given by it to the Agent or the Lenders hereunder;

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

(h) any inaccuracy or incompleteness of the Borrower’s representations and warranties contained in Article 7;

(i) any failure of the Borrower to observe or fulfil its covenants under Article 8; or

(j) the occurrence of any Default or Event of Default;

provided that this Section shall not apply to any losses, claims, costs, damages or liabilities that arise by reason of the gross negligence or wilful misconduct of the Indemnified Party claiming indemnity hereunder. The provisions of this Section shall survive repayment of the Loan Indebtedness.

13.3 Currency Indemnity

Any payment made to or for the account of a Lender in respect of any amount payable by the Borrower in a currency (the “Tendered Currency”) other than the currency in which such payment is due (the “Required Currency”), whether pursuant to any judgment or order of a court or tribunal or otherwise, shall constitute a discharge of the Borrower only to the extent of the amount of the Required Currency which may be purchased with such Tendered Currency at the time of payment at the Noon Rate at such time. The Borrower covenants and agrees to and in favour of each Lender that it shall, as a separate and independent obligation which shall not be merged in any such judgment or order, pay or cause to be paid the amount not so discharged in accordance with the foregoing and indemnify and hold harmless each Lender against any loss or damage arising as a result of any such amount being paid in such Tendered Currency. A certificate of the Agent as to any such loss or damage shall be prima facie evidence of the amount thereof in the absence of manifest error.

13.4 LC Issuer Indemnity

The Borrower shall indemnify and save harmless the LC Issuer from all claims, demands, liabilities, damages, losses, costs, charges and expenses which may be asserted against or incurred by the LC Issuer, otherwise than as are determined by a court of competent jurisdiction to be attributable to the gross negligence or willful misconduct of the LC Issuer, as a direct or indirect consequence of the issuance of any Letter of Credit at the request of the Borrower or of any failure by the LC Issuer to make any payment under any Letter of Credit issued at the request of the Borrower as a result of any law, control or restriction rightfully or wrongfully exercised or imposed by a domestic or foreign Governmental Authority.

ARTICLE 14
AGENCY AND ADMINISTRATION PROVISIONS

14.1 Authorization and Action

(a) Each Lender on its own behalf (and, for the purposes of Article 10 and the Swap Guarantee, on behalf of each of its Affiliates which is or becomes a Swap 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 14.9, 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 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 any loss, liability, cost or expense incurred, or to be incurred or which is contrary to this Agreement or Laws.

(b) Except as provided otherwise in Section 14.1(e), where the terms of this Agreement or the Security refer to any action to be taken hereunder or thereunder by the Lenders or to any such action that requires the consent, approval, satisfaction, agreement or other determination of the Lenders, the action taken by and the consent, approval, satisfaction, agreement or other determination given or made by the Majority Lenders shall constitute the action or consent, approval, agreement or other determination of the Lenders herein or therein referred to.

(c) Except as provided otherwise in this Section 14.1, the Agent shall have the right to take such actions as it deems necessary, or to refrain from taking such actions or to give agreements, consents, approvals or instructions to the Borrower on behalf of the Lenders in respect of all matters referred to in or contemplated by this Agreement.

(d) Except as provided otherwise in Section 14.1(e) or where this Agreement expressly requires that any matter be determined or consented to by all the Lenders, any provision of this Agreement may be amended only if the Borrower and the Majority Lenders so agree in writing and any Default or Event of Default may be waived before or after it occurs only if the Majority Lenders so agree in writing.

(e) Any amendment, extension or waiver of, or consent or determination relating to, the terms of this Agreement which changes or relates to:

(i) the Total Commitment or the Commitment of any Lender except as permitted by this Agreement;

(ii) a decrease in the rates, or an extension in the dates of payment, of interest payable hereunder;

(iii) a decrease in the amount, or an extension in the dates of payment, of fees payable hereunder except for (A) fronting fees payable pursuant to Section 3.5 (which may be varied with the consent of the LC Issuer) and (B) agency fees payable pursuant to Section 3.8 (which may be varied with the consent of the Agent);

(iv) a decrease in the amount, or an extension in the dates of payment, of principal required hereunder;

(v) the types of Advances available hereunder;

(vi) the extension provisions in Section 2.3 except for the notice periods referred to therein;

(vii) an assignment or transfer by the Borrower of any or all of its rights and obligations under this Agreement;

(viii) any release of the Security;

(ix) any assignment or transfer by a Restricted Subsidiary of, or release or amendment of, any or all of its obligations under any Restricted Subsidiary Guarantee not provided for hereunder;

(x) Section 14.17 (a)(ii); or

(xi) this Section 14.1(e);

shall require the unanimous consent in writing of all the Lenders; provided that:

(A) any amendment or waiver which changes or relates to the rights or obligations of the Agent, any LC Issuer or the Swing Line Lender

shall also require the agreement of the Agent, the LC Issuer or such Swing Line Lender, as applicable; and

(B) any amendment or waiver which changes or relates to Section 10.3 or this paragraph (B) or which would adversely affect in any material way the Security insofar as it pertains to a Swap Lender shall also require the agreement of the Swap Lender so affected;

and all references to unanimous consent in such context shall be construed accordingly.

(f) If any matter requiring unanimous consent of the Lenders pursuant to Section 14.1(e) is approved by the Majority Lenders (the “Consenting Lenders”) but there are Lenders which did not agree to provide their consent (each being a “Non-Consenting Lender”), then:

(i) the Borrower may require any Non-Consenting Lender to assign all of its rights, benefits and interests under its Commitments and its Pro Rata Shares of all Loan Indebtedness then outstanding (collectively, the “Assigned Interests”) to (A) any Consenting Lenders which have agreed to increase their Commitments and purchase Assigned Interests, and (B) to the extent the Assigned Interests are not transferred to Consenting Lenders, assignees selected by the Borrower and acceptable to the Agent and any LC Issuer, each acting reasonably. Such assignments shall be effective upon execution of Lender Assignment Agreements, upon payment to the relevant Non-Consenting Lender (in immediately available funds) by the relevant assignee of an amount equal to its Pro Rata Shares of all Loan Indebtedness being assigned, upon execution of an intercreditor agreement if requested by such Non-Consenting Lender pursuant to Section 10.3 (but only if such Non-Consenting Lender or its Affiliate is a Swap Lender) and upon payment by the relevant assignee to the Agent (for the Agent’s own account) of the transfer fee contemplated in Section 15.1(b). Upon such assignment and transfer, the Non-Consenting Lender shall have no further right, interest or obligation in respect of the Assigned Interests and the assignee thereof shall succeed to the position of such Lender as if the same was an original party hereto in the place and stead of such Non-Consenting Lender; and

(ii) to the extent that the Borrower has not caused any Non-Consenting Lender to assign its rights and interests to a Consenting Lender or other assignee as provided in paragraph (i) above, the Borrower may, at any time and notwithstanding any other provision hereof, repay to such Non-Consenting Lender its Pro Rata Shares of all Loan Indebtedness then outstanding, without making corresponding repayments to the Consenting Lenders, and the Borrower may cancel such Non-Consenting Lender’s Commitments; provided that such cancellation shall require the prior consent of all of the Consenting Lenders and shall also require the execution of an intercreditor

agreement if requested by such Non-Consenting Lender pursuant to Section 10.3 (but only if such Non-Consenting Lender or its Affiliate is a Swap Lender). Upon completion of the foregoing, such Non-Consenting Lender shall have no further right, interest, benefit or obligation in respect of the Credit Facility and the Total Commitment shall be reduced by the amount of such Non-Consenting Lender’s cancelled Commitments;

provided that the Borrower may only exercise its rights under this Section 14.1(f) by giving notice to the Agent of its intent to do so within 60 days after being notified of the lack of unanimous consent and then only if all of the Commitments of all of the Non-Consenting Lenders are assigned or cancelled in accordance with the provisions of this Section 14.1(f). Any assignment or prepayment pursuant to this Section 14.1(f) shall be subject to the indemnification provisions in Sections 13.2(d) and 13.2(e), if applicable.

(g) The Agent shall declare an Event of Default and demand payment under Section 11.2 of any or all of the Loan Indebtedness when directed to do so by written notice of the Majority Lenders.

14.2 Procedure for Making Drawdowns

(a) Unless the Agent has been notified by a Lender at least one Banking Day prior to the Drawdown Date requested by the Borrower that such Lender will not make available to the Agent its Pro Rata Share of the relevant Advance, the Agent may assume that such Lender has made or will make such portion of such Advance available to the Agent on the Drawdown Date 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 Pro Rata Share of an Advance available to the Agent, such Lender agrees to pay to the Agent forthwith on demand such Lender’s Pro Rata Share of the Advance and all reasonable costs and expenses incurred by the Agent in connection therewith together with interest thereon (at the usual inter-bank offered rate for the sale of deposits in the applicable currency or, if such Lender becomes a Defaulting Lender, the rate payable hereunder by the Borrower for the Advance in each case 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 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 Pro Rata Share of the Advance for purposes of this Agreement.

(b) After the Agent is notified by the Borrower of a pending sale of Bankers’ Acceptances to third party purchaser(s) in accordance with Section 4.5(b), each Lender may, in its discretion, assume that the applicable purchaser will be remitting the applicable BA Discount Proceeds to such Lender on the applicable issue date in accordance with the Borrower’s settlement instructions and such Lender may, in its discretion and in reliance upon such assumption, remit to the Agent on such issue date an amount equal to such BA Discount Proceeds (net of the BA Stamping Fee payable to such Lender) in accordance with Section 4.5(d). If the applicable purchaser does not in fact remit such funds to such Lender on such issue date, such Lender shall promptly notify the Agent who shall promptly notify the Borrower and the Borrower shall forthwith, on demand by the Agent, pay to the Agent for the account of such Lender such amount together with such interest thereon as may be reasonably required to compensate such Lender for such purchaser’s non-payment if such payment is not made on such issue date, as determined by such Lender in accordance with its usual banking practices.

14.3 Remittance of Payments

Except for amounts payable to the Agent for its own account, forthwith after receipt of any repayment of principal, interest or fees pursuant hereto, the Agent shall remit to the Designated Lending Branch of each Lender its Pro Rata Share 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 Pro Rata Share 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 customarily applicable to interbank payments 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 a Lender (an “Overpaid Lender”) shall obtain any payment (an “Excess Payment”), whether voluntary, involuntary, through the exercise of any right of set-off or otherwise (other than any amounts expressly permitted to be paid solely to such Lender pursuant to this Agreement), to be applied on account of any portion of the Loan Indebtedness owed to it in excess of its Pro Rata Share thereof, then:

(i) such Overpaid Lender shall purchase, on a non-recourse basis and at par, portions of the Outstandings owed to the other Lenders in an amount equal to the Excess Payment and in such proportions that after such purchase

each Lender will be owed its Pro Rata Share of the Loan Indebtedness, whereupon the Agent shall notify the Borrower of such amount and of its receipt by the Agent;

(ii) such Overpaid Lender shall immediately pay to the Agent an amount equal to the Excess Payment and the Agent shall remit to each Lender (other than the Overpaid Lender) its Pro Rata Share of such Excess Payment (calculated without reference to the share of the Overpaid Lender); and

(iii) the Agent shall notify the Borrower of its receipt of the Excess Payment and:

(A) as between the Borrower and the Overpaid Lender, the Excess Payment shall, except as provided in paragraph (B) below, be treated as not having been paid; and

(B) as between the Borrower and each Lender (other than the Overpaid Lender), the applicable share of the Excess Payment shall be treated as having been paid to each such Lender on the date such Excess Payment was made to the Overpaid Lender;

provided that if all or any portion of such Excess Payment is subsequently recovered or otherwise required to be repaid by the Overpaid Lender to the Borrower or any trustee, liquidator, receiver, receiver-manager or Person with analogous powers, each other Lender will promptly repay to the Agent for the account of such Overpaid Lender an amount equal to any amount which such other Lender had received pursuant to this Section 14.4;

(b) if such Lender or its Affiliate exercises any security against or right of counter-claim, set off or banker’s lien 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, such Lender or its Affiliate shall apportion the amount thereof proportionately between:

(i) all outstanding Loan Indebtedness owing by the Borrower (including the face amounts at maturity of Bankers’ Acceptances accepted by the Lenders), which amounts shall be applied in accordance with Section 14.4(a); and

(ii) all Senior Secured Swap Obligations owing by the Borrower and the Restricted Subsidiaries, which amounts shall be shared among the Swap Lenders in accordance with Section 10.3 (and, for such purposes, the provisions of Section 14.4(a) shall apply mutatis mutandis),

provided that these provisions do not apply to:

(A) any cash collateral posted as security for the Huntsman Preferred Stock Obligations or any other Permitted Lien;

(B) any netting arrangements or other set-off of obligations under any Hedging Agreements with the Swap Lenders;

(C) any cash collateral provided, or the exercise of rights of counterclaim, set-off or banker’s lien or similar rights, in respect of account positioning arrangements for the Borrower and its Subsidiaries provided by a Lender in the ordinary course of business or in respect of other cash management services provided by a Lender in the ordinary course of business;

(D) any payment to which a Lender is entitled as a result of any credit derivative or other form of credit protection obtained by such Lender; or

(E) any accounts receivable which are included in a Permitted Securitization Program (including the proceeds received by the purchaser of such receivables); and

(c) if such Lender or its Affiliate does, or is required to do, any act or thing permitted by Section 14.4(a) or 14.4(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:

(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 Lender Assignment Agreement;

(b) may consult with legal counsel (including receiving the opinions of Borrower’s Counsel and Lenders’ 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 of 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 Default or 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 opinion constitute a breach of any Laws, 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 reasonable opinion be contrary to any Laws or any directive or otherwise render it liable to any Person, and may do anything which is in its reasonable opinion necessary to comply with such Laws.

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 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 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 Lenders’ Authorities

With respect to its Commitments and its Pro Rata Shares of the Drawdowns, Rollovers and Conversions 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 the Subsidiaries. Each Lender confirms 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 and the Subsidiaries, 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 and the 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 it will not make any arrangements with the Borrower for the satisfaction of any Advances or other Loan Indebtedness without the consent of all 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, 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 (adjusted 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

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, after soliciting the views of the Borrower, 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.

14.11 Taking and Enforcement of Remedies

(a) Each of the Lenders hereby acknowledges that, to the extent permitted by Laws, 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 Lenders regardless of whether any Loan Indebtedness is accelerated 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 Facility, including, without limitation, any exercise of any remedies 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 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 the Majority 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 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 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 it has not heretofore and shall not seek, take, accept or receive any security for any of the Loan Indebtedness 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 relating in any manner whatsoever to the Credit Facility (except as expressly contemplated under this Agreement), unless all of the Lenders shall at the same time obtain the benefit of any such security or agreement.

(b) 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 Pro Rata Shares 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.

14.12 Adjustments Among Lenders

(a) Adjustments to Outstandings. Each Lender agrees that, after acceleration of any Outstandings pursuant to Section 11.2, it will at any time and from time to time, upon the request of the Agent as required by any Lender, purchase portions of the Outstandings made available by the other Lenders and make any other adjustments which may be necessary or appropriate, in order that the proportionate amount of Outstandings owed to each Lender, as adjusted pursuant to this Section 14.12, will be on a Pro Rata Basis at such time.

(b) Application of Payments. The Lenders agree that, after acceleration of any Outstandings pursuant to Section 11.2, the amount of any repayment made by the Borrower under this Agreement, and the amount of any proceeds from the exercise of any rights or remedies of the Lenders under the Loan Documents, which are to be applied against amounts owing hereunder, will be so applied in a manner so that, to the extent possible, the proportionate amount of Outstandings owed to each Lender which remain outstanding after giving effect to such application and any adjustments made pursuant to Section 14.12(a) will be on a Pro Rata Basis as of the date of acceleration (subject to adjustment as required to reflect any Conversion of Swing Line Advances to Advances pursuant to Section 2.11(d)).

(c) Further Assurances. The Borrower agrees to be bound by and, at the request of the Agent, to do all things necessary or appropriate to give effect to any and all purchases and other adjustments made by and between the Lenders pursuant to

this Section 14.12, but shall incur no increased liabilities, costs or expenses, in aggregate, by reason thereof.

14.13 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.

14.14 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.

14.15 Article for Benefit of Agent and Lenders

The provisions of this Article 14 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 expressly provided for in this Article, 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.

14.16 Cash Collateral and Withholding from a Defaulting Lender

(a) Each Defaulting Lender shall be required to provide to the Agent cash in such amount, as determined from time to time by the Agent in its reasonable discretion, equal to all obligations of such Defaulting Lender which are either then owing under this Agreement or, in the case of contingent obligations under any outstanding Letters of Credit or Swing Line Advance (after giving effect to the re-allocation provisions in Section 14.17), may become owing to any LC Issuer or Swing Line Lender.

(b) The Agent shall be entitled to withhold from any Defaulting Lender’s Pro Rata Share of all payments received from the Borrower hereunder such amount as such Defaulting Lender is required to provide as cash collateral under Section 14.16(a) and the Agent is entitled to set-off such amounts against such Defaulting Lender’s defaulted obligations to fund amounts previously required to be paid by such

100

Defaulting Lender under this Agreement and to purchase participations previously required to be purchased by such Defaulting Lender under this Agreement.

(c) All funds received by the Agent pursuant to Sections 14.16(a) and 14.16(b) shall be deposited by the Agent in one or more cash collateral accounts in the name of the Agent, which amounts shall be used by the Agent:

(i) first, to reimburse the Agent for any amounts owing to it, in its capacity as Agent, by the Defaulting Lender pursuant to any Loan Document;

(ii) second, to repay on a Pro Rata Basis the incremental portion of any Loan Indebtedness made by a Non-Defaulting Lender pursuant to Section 14.17 in order to fund a funding shortfall created by a Defaulting Lender and, upon receipt of such repayment, each such Non-Defaulting Lender shall be deemed to have assigned to the Defaulting Lender such incremental portion of such Loan Indebtedness; and

(iii) third, to cash collateralize all other contingent obligations of such Defaulting Lender to the Agent, any LC Issuer or any Swing Line Lender which are outstanding pursuant to this Agreement in such amount as shall be determined from time to time by the Agent in its reasonable discretion;

provided that any such funds in excess of such Defaulting Lender’s defaulted obligations shall be paid to the Defaulting Lender.

(d) For greater certainty and in addition to the foregoing, neither the Agent nor any of its Affiliates nor any of their respective shareholders, officers, directors, employees, agents or representatives shall be liable to any Lender (including, without limitation, a Defaulting Lender) for any action taken or omitted to be taken by it in connection with amounts payable by the Borrower to a Defaulting Lender and received and deposited by the Agent in a cash collateral account and applied in accordance with the provisions of this Agreement, except for the gross negligence or wilful misconduct of the Agent as determined by a final non-appealable judgement of a court of competent jurisdiction.

14.17 Funding Where There is a Defaulting Lender

(a) Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(i) the standby fees payable pursuant to Section 3.6 shall cease to accrue on the unused portion of the Commitment of such Defaulting Lender if and for so long as such Lender is a Defaulting Lender pursuant to (i) or (ii) of the definition thereof;

(ii) a Defaulting Lender shall not be included in determining whether, and the Commitments and Lender’s proportions of such Defaulting Lender shall be

101

excluded in determining whether, all Lenders or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 14.1(e)); provided that any waiver, amendment or modification that (A) applies to such Defaulting Lender in a manner that differs in any material respect from its application to other affected Lenders, (B) increases any Commitment of such Defaulting Lender, (C) extends any Maturity Date applicable to such Defaulting Lender, (D) decreases the Applicable Pricing Margin, Utilization Fee or standby fees applicable to such Defaulting Lender or (E) postpones, reduces or waives any principal payment due to such Defaulting Lender hereunder shall in each case require the consent of such Defaulting Lender; and

(iii) for certainty, the Borrower shall retain and reserve its other rights and remedies respecting each Defaulting Lender;

provided that the Agent shall only be required to give effect to (i) and (ii) above if the Agent has actual knowledge that a Lender is a Defaulting Lender. If the Agent acquires actual knowledge that a Lender is a Defaulting Lender, then the Agent shall promptly notify the Borrower that such Lender is a Defaulting Lender (and such Lender shall be deemed to have consented to such disclosure); provided that the Agent shall have no duty to inquire as to whether a Lender is a Defaulting Lender.

(b) If the Agent has actual knowledge that a Lender is a Defaulting Lender at the time that the Agent receives a Notice of Borrowing that relates to a Letter of Credit or that either relates to a Swing Line Advance or will result in a currency conversion, then each Non-Defaulting Lender shall fund its Lender’s proportion of such affected Loan Indebtedness (and, in calculating such Lender’s proportion, the applicable Commitment of each such Defaulting Lender shall be ignored); provided that such re-allocation may only be effected if and to the extent that (i) such re-allocation would not cause any Non-Defaulting Lender’s proportion of all Outstandings to exceed its Commitment and (ii) the conditions precedent in Section 9.2 are satisfied at such time. Each Defaulting Lender agrees to indemnify each Non-Defaulting Lender for any amounts paid by such Non-Defaulting Lender under this Section 14.17 and which would otherwise have been paid by the Defaulting Lender if its Commitment had been included in determining the Lender’s Pro Rata Share of such affected Advances.

(i) all or any part of such Defaulting Lender’s Pro Rata Share of such Letter of Credit shall be re-allocated among the Non-Defaulting Lenders in accordance with their respective Commitments; provided that such re-allocation may only be effected if and to the extent that (A) such re-allocation would not cause any Non-Defaulting Lender’s Commitment of

102

all Outstandings to exceed its Commitment and (B) the conditions precedent in Section 9.2 are satisfied at such time;

(ii) if the re-allocation described in clause (i) above cannot be effected, or can only partially be effected, then such Defaulting Lender shall, within one Banking Day following notice by the Agent, provide cash collateral for such Defaulting Lender’s Commitment of such Letter of Credit (after giving effect to any partial re-allocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 14.16 for so long as such Letter of Credit is outstanding; and

(iii) if the Lender’s Commitment of the Non-Defaulting Lenders are re-allocated pursuant to this Section 14.17(c), then the issuance fees payable to the Lenders pursuant to Section 3.5 shall be adjusted to give effect to such re-allocations in accordance with each such Non-Defaulting Lender’s Commitment.

(d) So long as any Lender is a Defaulting Lender, no LC Issuer shall be required to issue, amend or increase any Letter of Credit, and no Swing Line Lender shall be required to make any Swing Line Advance, unless such LC Issuer or Swing Line Lender as applicable is satisfied that the related exposure will be 100% covered by the Commitments of the Non-Defaulting Lenders and/or cash collateralized in accordance with Section 14.17(c), and participating interests in any such newly issued or increased Letter of Credit or Swing Line Advance shall be allocated among Non-Defaulting Lenders in a manner consistent with Section 14.17(b) or 14.17(c)(i) as applicable (and Defaulting Lenders shall not participate therein).

(e) If any Lender shall cease to be a Defaulting Lender, then, upon becoming aware of such change, the Agent shall notify the Non-Defaulting Lenders and (in accordance with the written direction of the Agent) such Lender (which has ceased to be a Defaulting Lender) shall purchase, and the Non-Defaulting Lenders shall on a rateable basis sell and assign to such Lender, portions of such Loan Indebtedness equal in total to such Lender’s Commitment thereof without regard to this Section 14.17.

ARTICLE 15
ASSIGNMENT

15.1 Assignment and Participation Prior to Default

(a) Any Lender (a “Granting Lender”) may grant a participation in the Credit Facility to one or more Persons (each a “Participant”). If such a participation is granted, (i) the Granting Lender shall remain fully liable for all of its obligations and responsibilities hereunder to the same extent as if such participation had not been granted, and (ii) the Granting Lender shall administer the participation of the Participant and none of the Participant, the Borrower and the Agent shall have any

103

rights against or obligations to one another, nor shall any of them be required to deal directly with one another in respect of the participation by such Participant.

(b) With the prior written consent of the Borrower, the Agent, and any LC Issuer and the Swing Line Lender (which cannot be unreasonably withheld), any Lender (an “Assigning Lender”) may assign all or any part of such Lender’s rights to, and may have its respective obligations in respect of, the Credit Facility assumed by one or more Persons (each an “Assignee”). No such consents shall be required in the case of an assignment to an Affiliate but the Assigning Lender shall not be released from its obligations hereunder unless such consents are obtained. Any permitted assignment shall become effective when the Agent and the Borrower have been notified of it by the Assigning Lender, have received from the Assignee an executed copy of a Lender Assignment Agreement, and the Agent has received from the Assignor an assignment fee of U.S. $2,500 (other than in respect of the initial syndication of the Credit Facility or in respect of an assignment to an Affiliate of the Assigning Lender). Any Assignee of a Lender shall be and be treated as a Lender for all purposes of this Agreement, and each Assignee shall be entitled to the full benefit hereof and shall be subject to the obligations of the Assigning Lender to the same extent as if it were an original party in respect of the rights or obligations assigned to it and the Assigning Lender shall be released and discharged accordingly and to the same extent, and Schedule A (to the extent such Schedule relates to the Assigning Lender) shall be deemed to be amended accordingly from time to time without further notice or other requirement.

(c) No Lender shall be entitled to grant a participation under Section 15.1(a) or an assignment under Section 15.1(b) or to change its Lender’s Designated Branch, as the case may be, if this would, immediately following such participation or assignment or change of Lender’s Designated Branch (or within a reasonably foreseeable period of time thereafter), (i) create or increase any liability on the part of the Borrower in respect of Taxes, (ii) increase the cost of the Credit Facility to the Borrower or result in any increase in obligations of the Borrower, (iii) result in any reduction of rights of the Borrower, or (iv) result in any increase in the amount that the Borrower is obligated to pay pursuant to any of the Loan Documents.

(d) The Borrower will, at the applicable Lender’s expense, execute such further documents and instruments and do such further things as the Agent or such Lender may reasonably request for the purpose of any participation or assignment.

(e) Notwithstanding any other provision of Section 15.1, no Assigning Lender shall assign an interest to an Assignee unless (i) the Assignee, if it is not an existing Lender, acquires any Commitment(s) with an aggregate principal amount of not less than U.S. $10,000,000, and (ii) the Assigning Lender, if it retains any Commitments, retains any Commitment(s) with an aggregate principal amount of not less than U.S. $10,000,000.

104

(f) Notwithstanding any other provision of Section 15.1, the Swing Line Lender may only assign all (but not less than all) of its Swing Line Commitment.

15.2 Assignment After Event of Default

Notwithstanding anything to the contrary herein contained, if an Event of Default has occurred and is continuing, nothing in this Agreement shall:

(a) require the consent of the Borrower to an assignment by a Lender to any Person of all or any part of its rights and obligations under or with respect to this Agreement and any Loan Indebtedness owing to it; or

(b) impose limits upon the amount of the Commitment assigned or retained by the assigning Lender.

15.3 Assignment by Borrower

The Borrower shall not assign, delegate or transfer all or any part of its rights or obligations hereunder without the prior written consent of all the Lenders.

15.4 Replacement of Dissenting Lenders

If (a) the Borrower requests a consent, waiver or approval from the Lenders under this Agreement which is consented to by two or more Lenders holding Commitments which in the aggregate exceed 50% of the Total Commitment (in this Section 15.4 called the “Consenting Lenders”) and (b) one or more Lenders (in this Section 15.4 called the “Dissenting Lender(s)”) withholds its or their consent to such request and, as a result, the consent, waiver or approval of the required Lenders cannot be obtained in connection with such request, the Borrower may, by giving notice to each Dissenting Lender and to the Agent within 90 days of being advised by the Agent of whether the Lenders have consented to or approved such request:

(i) require each Dissenting Lender to assign all or any part of its rights, benefits and interests under its Commitments and its Pro Rata Shares of all Loan Indebtedness then outstanding in the same manner and subject to the same conditions provided for in Section 2.3(f)(i); and

(ii) to the extent that the Borrower has not caused each Dissenting Lender to assign all of its rights and interests as provided in paragraph (i) above, permanently repay to each such Dissenting Lender its Pro Rata Shares of all Loan Indebtedness then outstanding in the same manner and subject to the same conditions provided for in Section 2.3(f)(ii); provided that, for certainty, such permanent repayment and cancellation shall require the prior consent of all of the Consenting Lenders.

105

106

a duty of confidentiality to the Borrower at the time the information was so received;

16.2 Telephone Instructions

Any verbal instructions given by the Borrower in relation to this Agreement will be at the risk of the Borrower and neither the Agent nor the Lenders will have any liability for any error or omission in such verbal instructions or in the interpretation or execution thereof by the Agent or a Lender, as the case may be, provided the Agent or Lender, as the case may be, acted without gross negligence in the circumstances. The Agent will notify the Borrower of any conflict or inconsistency between any written confirmation of such verbal instructions received from the Borrower and the said verbal advice as soon as practicable after the conflict or inconsistency becomes apparent to the Agent.

16.3 Further Assurances

Each Party hereto shall, at the request of the other (but at the expense of the Borrower), perform all such further acts and execute and deliver all such further documents as may, in the reasonable opinion of the other, be necessary or desirable in order to fully perform and carry out the purpose and intent of the Loan Documents.
