          NOW, THEREFORE, in consideration of the premises and the mutual covenants hereinafter contained, and for other good and valuable consideration, the parties hereto agree as follows:

1. AMOUNT AND TERMS OF CREDIT

          1.1 Credit Facilities.

          (a) Revolving Credit Facility.

               (i) Subject to the terms and conditions hereof, each Lender agrees to make available to US Borrowers and to Canadian Borrowers from time to time until the

Commitment Termination Date its Pro Rata Share of advances (each, a “Revolving Credit Advance”) provided that all Revolving Credit Advances hereunder to US Borrowers shall be made by US Lenders and all Revolving Credit Advances hereunder to Canadian Borrowers shall be made by Canadian Lenders. The aggregate amount of all Revolving Credit Advances to US Borrowers shall not exceed $225,000,000, and the aggregate amount of all Revolving Credit Advances to Canadian Borrowers shall not exceed the Dollar Equivalent Amount of $50,000,000. The Pro Rata Share of the Revolving Loan of any Lender shall not at any time exceed its applicable Revolving Loan Commitment (as determined separately in respect of US Borrowers, on the one hand, and Canadian Borrowers, on the other hand). The obligations of each Lender hereunder shall be several and not joint. Until the Commitment Termination Date, Borrowers may from time to time borrow, repay and reborrow under this Section 1.1(a); provided, that (A) the amount of any Revolving Credit Advance to be made at any time to US Borrowers shall not exceed US Borrowing Availability at such time; (B) the amount of any Revolving Credit Advance to be made at any time to Canadian Borrowers shall not exceed Canadian Borrowing Availability at such time; and (C) the aggregate amount of Revolving Credit Advances shall not exceed Borrowing Availability to all Borrowers. Borrowing Availability may be further reduced by Reserves imposed by Agent in its reasonable credit judgment. Moreover, the sum of the Revolving Loan and Swing Line Loan outstanding to (I) all US Borrowers shall not exceed at any time the US Borrowing Base and (II) all Canadian Borrowers shall not exceed at any time the Canadian Borrowing Base. Each Revolving Credit Advance shall be made on notice by Borrower Representative on behalf of the applicable Borrower to one of the representatives of Agent identified in Schedule 1.1 at the address specified therein and in the case of Canadian Revolving Credit Advances, to the Canadian Agent as well. Any such notice must be given no later than (1) 12:00 noon (New York time) on the Business Day of the proposed Revolving Credit Advance, in the case of an Index Rate Loan, or (2) 12:00 noon (New York time) on the date which is 3 Business Days prior to the proposed Revolving Credit Advance, in the case of a LIBOR Loan or BA Rate Loan. Each such notice (a “Notice of Revolving Credit Advance”) must be given in writing (by telecopy or overnight courier) substantially in the form of Exhibit 1.1(a)(i), and shall include the information required in such Exhibit and such other information as may be required by Agent. If any Borrower desires to have the Revolving Credit Advances bear interest by reference to a LIBOR Rate or BA Rate, Borrower Representative must comply with Section 1.5(e).

               (ii) Except as provided in Section 1.12, each US Borrower shall execute and deliver to the Agent for delivery to each US Lender a single note to evidence the Revolving Loan Commitment of that US Revolving Lender, and each Canadian Borrower shall execute and deliver to the Agent for delivery to each Canadian Lender a single note to evidence the Revolving Loan Commitment of that Canadian Lender. Each note shall be in the principal amount of the Revolving Loan Commitment of the applicable Lender, dated the Closing Date and substantially in the form of Exhibit 1.1(a)(ii) (each a “Revolving Note” and, collectively, the “Revolving Notes”). Each Revolving Note shall represent the obligation of the applicable Borrower to pay the amount of the applicable Lender’s Revolving Loan Commitment or, if less, such Lender’s Pro Rata Share of the aggregate unpaid principal amount of all US Revolving Credit Advances to such US Borrower or Canadian Revolving Credit Advances to such Canadian Borrower, as applicable in each case together with interest thereon as prescribed in Section 1.5.

The entire unpaid balance of the Revolving Loan and all other non-contingent Obligations shall be immediately due and payable in full in immediately available funds on the Commitment Termination Date.

               (iii) Any provision of this Agreement to the contrary notwithstanding, at the request of Borrower Representative, in its discretion (A) Agent may (but shall have absolutely no obligation to), make Revolving Credit Advances to US Borrowers on behalf of US Lenders in amounts that cause the outstanding balance of the US Revolving Loan to exceed the US Borrowing Base (less the US Swing Line Loan), and (B) Canadian Agent may (but shall have absolutely no obligation to), make Revolving Credit Advances to Canadian Borrowers on behalf of Canadian Lenders in amounts that cause the outstanding balance of the Canadian Revolving Credit Advance to exceed the Canadian Borrowing Base (less the Canadian Swing Line Advances) (any such excess US or Canadian Revolving Credit Advances are herein referred to collectively as “Overadvances”); provided that (A) no such event or occurrence shall cause or constitute a waiver of Agent’s, Canadian Agent’s, the Swing Line Lender’s or Lenders’ right to refuse to make any further Overadvances, Swing Line Advances or Revolving Credit Advances, or incur any Letter of Credit Obligations, as the case may be, at any time that an Overadvance exists, and (B) no Overadvance shall result in a Default or Event of Default due to Borrowers’ failure to comply with Section 1.3(a)(i) for so long as Agent or Canadian Agent permits such Overadvance to remain outstanding, but solely with respect to the amount of such Overadvance. In addition, Overadvances may be made even if the conditions to lending set forth in Section 2 have not been met. All Overadvances shall constitute Index Rate Loans, shall bear interest at the Default Rate and shall be payable on demand. Except as otherwise provided in Section 1.11(b), (A) the authority of Agent to make Overadvances is limited to an aggregate amount not to exceed $15,000,000 at any time, (B) the authority of Canadian Agent to make Overadvances is limited to an aggregate amount not to exceed CD$ 3,000,000 at any time, (C) in no event shall either Agent permit any Overadvance to cause (1) the aggregate Revolving Loan to exceed the Maximum Amount, (2) the aggregate US Revolving Loan to exceed the Maximum US Amount, or (3) the aggregate Canadian Revolving Loan to exceed the Maximum Canadian Amount and (D) in no event shall either Agent permit any Overadvance to remain outstanding for more than 90 days in any 180-day period, and may be revoked prospectively by a written notice to such Applicable Agent signed by, in the case of Overadvances pursuant to clause (A), US Lenders holding more than 50% of the US Revolving Loan Commitments and in the case of Overadvances pursuant to clause (B), Canadian Lenders holding more than 50% of the Canadian Revolving Loan Commitments.

          (b) Swing Line Facility.

               (i) Agent shall notify the Swing Line Lender upon Agent’s receipt of any Notice of Revolving Credit Advance. Subject to the terms and conditions hereof, the Swing Line Lender may, in its discretion, make available from time to time until the Commitment Termination Date advances (each, a “Swing Line Advance”) in accordance with any such notice, provided that all Swing Line Advances hereunder to US Borrowers shall be made by the applicable Swing Line Lender in Dollars (“US Swing Line Advances”) and all Swing Line Advances hereunder to Canadian Borrowers shall be made by the applicable Swing Line Lender in Canadian Dollars (“Canadian Swing Line Advances”). The provisions of this Section 1.1(b)

shall not relieve Lenders of their obligations to make Revolving Credit Advances under Section 1.1(a); provided that if the Swing Line Lender makes a Swing Line Advance pursuant to any such notice, such Swing Line Advance shall be in lieu of any Revolving Credit Advance that otherwise may be made by Lenders pursuant to such notice. The aggregate amount of Swing Line Advances outstanding (A) to US Borrowers shall not exceed at any time the lesser of (1) the Swing Line Commitment to US Borrowers and (2) the lesser of the Maximum US Amount and (except for Overadvances) the US Borrowing Base, in each case, less the outstanding balance of the US Revolving Loan at such time; and (B) to Canadian Borrowers shall not exceed at any time the lesser of (1) the Swing Line Commitment to Canadian Borrowers and (2) the lesser of the Maximum Canadian Amount and (except for Overadvances) the Canadian Borrowing Base, in each case, less the outstanding balance of the Canadian Revolving Loan at such time (in each case respectively under the preceding clause (A) or clause (B), “Swing Line Availability”). Moreover, except for Overadvances, the aggregate US Swing Line Advances shall not exceed at any time the US Borrowing Base less the US Revolving Loan, and the aggregate Canadian Swing Line Advances shall not exceed at any time the Canadian Borrowing Base less the Canadian Revolving Loan. Until the Commitment Termination Date, Borrowers may from time to time borrow, repay and reborrow under this Section 1.1(b). Each Swing Line Advance shall be made pursuant to a Notice of Revolving Credit advance delivered to Agent (and in the case of Canadian Swing Line Advances, to Canadian Agent as well) by Borrower Representative on behalf of the applicable Borrower in accordance with Section 1.1(a). Any such notice must be given no later than 1:00 p.m. (New York time) on the Business Day of the proposed Swing Line Advance. Unless the Swing Line Lender has received at least one Business Day’s prior written notice from Requisite Lenders instructing it not to make a Swing Line Advance, the Swing Line Lender shall, notwithstanding the failure of any condition precedent set forth in Section 2.2, be entitled to fund that Swing Line Advance, and to have such Lender make Revolving Credit Advances in accordance with Section 1.1(b)(iii) or purchase participating interests in accordance with Section 1.1(b)(iv). Notwithstanding any other provision of this Agreement or the other Loan Documents, the Swing Line Loan shall constitute a Loan bearing interest at the commercial paper rate plus the Applicable Revolver LIBOR Margin for US Swing Line Advances or the Index Rate plus the Applicable Revolver BA Margin for Canadian Swing Line Advances in Canadian Dollars as provided in Section 1.5(a) and no Swing Line Loan shall remain outstanding for more than fifteen (15) days. The applicable Borrowers shall repay to the Applicable Swing Line Lender the aggregate outstanding principal amount of the Swing Line Loan upon demand therefor by Agent.

               (ii) Each Borrower shall execute and deliver to the applicable Swing Line Lender a promissory note to evidence the Swing Line Commitment. Each note shall be in the principal amount of the Swing Line Commitment of such Swing Line Lender, dated the Closing Date and substantially in the form of Exhibit 1.1(b)(ii) (each a “Swing Line Note” and, collectively, the “Swing Line Notes”). Each Swing Line Note shall represent the obligation of each applicable Borrower to pay the amount of the Swing Line Commitment or, if less, the aggregate unpaid principal amount of all Swing Line Advances made to Borrowers together with interest thereon as prescribed in Section 1.5. The entire unpaid balance of the Swing Line Loan and all other noncontingent Obligations shall be immediately due and payable in full in immediately available funds on the Commitment Termination Date if not sooner paid in full.

               (iii) The Swing Line Lender (either the US or Canadian Swing Line Lender, as applicable), at any time and from time to time in its sole and absolute discretion, may, on behalf of any applicable Borrower (and each such Borrower hereby irrevocably authorizes the applicable Swing Line Lender to so act on its behalf), request each Lender (including the applicable Swing Line Lender) to make a Revolving Credit Advance to the applicable Borrower (which shall be an Index Rate Loan) in an amount equal to that Lender’s Pro Rata Share of the principal amount of the applicable Swing Line Loan (the “Refunded Swing Line Loan”) outstanding on the date such notice is given, provided that all Revolving Credit Advances to US Borrowers shall be made by US Lenders and all Revolving Credit Advances to Canadian Borrowers shall be made by Canadian Lenders. Unless any of the events described in Sections 8.1(h) or 8.1(i) has occurred (in which event the procedures of Section 1.1(b)(iv) shall apply) and regardless of whether the conditions precedent set forth in this Agreement to the making of a Revolving Credit Advance are then satisfied, each Lender shall disburse directly to Agent or Canadian Agent, as applicable, its Pro Rata Share of a Revolving Credit Advance on behalf of the Swing Line Lender, prior to 3:00 p.m. (New York time), in immediately available funds on the Business Day next succeeding the date that notice is given. The proceeds of those Revolving Credit Advances shall be immediately paid to the applicable Swing Line Lender and applied to repay the Refunded Swing Line Loan of the applicable Borrower.

               (iv) If, prior to refunding a Swing Line Loan with a Revolving Credit Advance pursuant to Section 1.1(b)(iii), one of the events described in Sections 8.1(h) or 8.1(i) has occurred, then, subject to the provisions of Section 1.1(b)(v) below, each applicable Lender shall, on the date such Revolving Credit Advance was to have been made for the benefit of the applicable Borrower, purchase from the applicable Swing Line Lender an undivided participation interest in the Swing Line Loan of the applicable Borrower in an amount equal to its Pro Rata Share of such Swing Line Loan. Upon request, each Lender shall promptly transfer to the applicable Swing Line Lender, in immediately available funds, the amount of its participation interest.

               (v) Each Lender’s obligation to make Revolving Credit Advances in accordance with Section 1.1(b)(iii) and to purchase participation interests in accordance with Section 1.1(b)(iv) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right that such Lender may have against the applicable Swing Line Lender, any Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of any Default or Event of Default; (C) any inability of any Borrower to satisfy the conditions precedent to borrowing set forth in this Agreement at any time or (D) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. If any Lender does not make available to Agent or Canadian Agent or the applicable Swing Line Lender, as applicable, the amount required pursuant to Sections 1.1(b)(iii) or 1.1(b)(iv), as the case may be, the applicable Swing Line Lender shall be entitled to recover such amount on demand from such Lender, together with interest thereon for each day from the date of non-payment until such amount is paid in full at the Federal Funds Rate for the first two Business Days and at the Index Rate thereafter.

          (c) Reliance on Notices, Appointment of Borrower Representative. Each Agent shall be entitled to rely upon, and shall be fully protected in relying upon, any Notice of Revolving Credit Advance, Notice of Conversion/Continuation or similar notice believed by each Agent to be genuine. Each Agent may assume that each Person executing and delivering any notice in accordance herewith was duly authorized, unless the responsible individual acting thereon for the Applicable Agent has actual knowledge to the contrary. Each Borrower hereby designates WESCO Distribution as its representative and agent on its behalf for the purposes of issuing Notices of Revolving Credit Advances and Notices of Conversion/Continuation, giving instructions with respect to the disbursement of the proceeds of the Loans, selecting interest rate options, requesting Letters of Credit, giving and receiving all other notices and consents hereunder or under any of the other Loan Documents and taking all other actions (including in respect of compliance with covenants) on behalf of any Borrower or Borrowers under the Loan Documents. Borrower Representative hereby accepts such appointment. Each Agent and each Lender may regard any notice or other communication pursuant to any Loan Document from Borrower Representative as a notice or communication from all Borrowers, and may give any notice or communication required or permitted to be given to any Borrower or Borrowers hereunder to Borrower Representative on behalf of such Borrower or Borrowers. Each Borrower agrees that each notice, election, representation and warranty, covenant, agreement and undertaking made on its behalf by Borrower Representative shall be deemed for all purposes to have been made by such Borrower and shall be binding upon and enforceable against such Borrower to the same extent as if the same had been made directly by such Borrower (subject to the limitations on Canadian Borrowers’ repayment and guaranty and security obligations set forth in Section 12).

          1.2 Letters of Credit. Subject to and in accordance with the terms and conditions contained herein and in Annex B, Borrower Representative, on behalf of the applicable Borrower, shall have the right to request, and US Lenders agree to incur, or purchase participations in, Letter of Credit Obligations in respect of each US Borrower (“US Letter of Credit Obligations”), and Canadian Lenders agree to incur, or purchase participations in, Letter of Credit Obligations denominated in Canadian Dollars in respect of each Canadian Borrower (“Canadian Letter of Credit Obligations”).

          1.3 Prepayments.

          (a) Voluntary Prepayments; Reductions in Revolving Loan Commitments. Borrowers may at any time on at least 5 days’ prior written notice by Borrower Representative to Agent permanently reduce (but not terminate) the Revolving Loan Commitment; provided that (A) any such reductions shall be in a minimum amount of $5,000,000 and integral multiples of $1,000,000 in excess of such amount, (B) the Revolving Loan Commitment shall not be reduced to an amount less than the amount of the Revolving Loan then outstanding, plus $25,000,000, and (C) after giving effect to such reduction, Borrowers shall comply with Section 1.3(b)(i). Borrowers may at any time on at least ten 10 days’ prior written notice by Borrower Representative to Agent terminate the Revolving Loan Commitment, provided that upon such termination all Loans and other Obligations shall be immediately due and payable in full and all Letter of Credit Obligations shall be cash collateralized or otherwise satisfied in accordance with Annex B hereto. Any reduction or termination of the Revolving Loan Commitment must be

8

accompanied by the payment of any LIBOR or BA Rate funding breakage costs in accordance with Sections 1.13(b) or 1.13(c). Upon any such reduction or termination of the Revolving Loan Commitment, Borrower’s right to request Revolving Credit Advances, or request that Letter of Credit Obligations be incurred on its behalf, or request Swing Line Advances, shall simultaneously be permanently reduced or terminated, as the case may be; provided that a permanent reduction of the Revolving Loan Commitment shall not require a corresponding pro rata reduction in the L/C Sublimit. Each notice of partial prepayment shall designate the Loans or other Obligations to which such prepayment is to be applied; provided, any partial prepayments or reduction in the Revolving Loan made by or on behalf of (i) any US Borrower shall be applied to the US Loans and (ii) any Canadian Borrower shall be applied to the Canadian Loans.

          (b) Mandatory Prepayments.

               (i) If at any time the US Borrowing Availability is less than zero, US Borrowers shall immediately repay the aggregate outstanding Revolving Credit Advances to the extent required to cause US Borrowing Availability to be at least zero. If US Borrowing Availability is less than zero after repayment in full of the aggregate outstanding US Revolving Credit Advances, US Borrowers shall provide cash collateral for the US Letter of Credit Obligations in the manner set forth in Annex B to the extent required to cause US Borrowing Availability to be at least zero. If at any time the Canadian Borrowing Availability is less than zero, Canadian Borrowers shall immediately repay the aggregate outstanding Revolving Credit Advances to the extent required to cause Canadian Borrowing Availability to be at least zero. If Canadian Borrowing Availability is less than zero after repayment in full of the aggregate outstanding Canadian Revolving Credit Advances, Canadian Borrowers shall provide cash collateral for the Canadian Letter of Credit Obligations in the manner set forth in Annex B to the extent required to cause Canadian Borrowing Availability to be at least zero. Notwithstanding the foregoing, any Overadvance made pursuant to Section 1.1(a)(iii) shall be repaid only on demand.

               (ii) Immediately upon receipt by any Credit Party of proceeds of any asset disposition (excluding proceeds of asset dispositions permitted by Section 6.8(a)) or any sale of Stock of any Subsidiary of any Credit Party or of any incurrence of Indebtedness in a mortgage financing transaction permitted under Section 6.3(a)(x) or the incurrence of any other Indebtedness from any third party in a transaction permitted under Section 6.3 (other than the issuance of additional Subordinated Notes or the Indebtedness pursuant to Sections 6.3(a) (xxii) and (xxiii), which shall be governed by clause (iv) below), Borrowers shall prepay the Loans in an amount equal to all such proceeds, net of (A) commissions and other reasonable and customary transaction costs, fees and expenses properly attributable to such transaction and payable by Borrowers in connection therewith (in each case, paid to non-Affiliates), (B) transfer taxes, (C) amounts payable to holders of senior Liens (to the extent such Liens constitute Permitted Encumbrances hereunder), if any, and (D) an appropriate reserve for income taxes in accordance with GAAP in connection therewith. Any such prepayment shall be applied in accordance with Section 1.3(c).

               (iii) If Holdings or any Borrower issues Stock, other than (i) the issuance of common Stock of Holdings in connection with 401(k) plans established for the benefit of employees, (ii) the issuance of common Stock upon the exercise of the stock options granted to employees pursuant to stock option plans adopted for the benefit of employees, (iii) the issuance of common Stock of Holdings pursuant to the provisions of Section 1.5(c)(v) of the Bruckner Acquisition Agreement and (iv) the issuance of common Stock of Holdings in connection with Permitted Acquisitions consummated in compliance with each of the terms and conditions of Section 6.1; provided, that, in the case of each of clauses (i), (ii), (iii) and (iv), there shall be no Change of Control upon any such issuance of common Stock of Holdings, and no later than the Business Day following the date of receipt of the proceeds thereof, Borrowers shall prepay the Loans in an amount equal to all such proceeds, net of underwriting discounts and commissions and other reasonable costs paid to non-Affiliates in connection therewith. Any such prepayment shall be applied in accordance with Section 1.3(c).

               (iv) If WESCO Distribution or WESCO International issues Indebtedness in a transaction permitted under Sections 6.3(a)(xxii) or (xxiii) and the other provisions of this Agreement, no later than forty-five (45) days following the date of receipt of the net proceeds thereof, Borrowers shall prepay the Loans in an amount equal to (i) the aggregate amount of such Indebtedness less (ii) the sum of (a) the aggregate amount of the Subordinated Notes that have been refinanced by such Indebtedness at such time, if any and (b) the purchase price paid pursuant to the Carlton-Bates Acquisition (and provided no Default or Event of Default shall have occurred or be continuing, with no corresponding permanent reduction of the Revolving Loan Commitment other than to the extent required pursuant to the terms of the documentation as of the Closing Date evidencing the Indebtedness issued pursuant to the terms of Section 6.3(a)(xxiii)). Any such prepayments shall be applied in accordance with Section 1.3(c).

          (c) Application of Certain Mandatory Prepayments. Any prepayments made by any Borrower pursuant to Sections 1.3(b)(ii) or (b)(iii) above shall be applied as follows: first, to Fees and reimbursable expenses of the Agents then due and payable pursuant to any of the Loan Documents; second, to interest then due and payable on the Swing Line Loan; third, to the principal balance of the Swing Line Loan until the same has been repaid in full; fourth, to interest then due and payable on the Revolving Credit Advances; fifth, to the outstanding principal balance of Revolving Credit Advances until the same has been paid in full; sixth, other than net proceeds from the issuance of common Stock and the issuance of Indebtedness in a transaction permitted under Sections 6.3(a)(xxii) or (xxiii), to any Letter of Credit Obligations, to provide cash collateral therefor in the manner set forth in Annex B, until all such Letter of Credit Obligations have been fully cash collateralized in the manner set forth in Annex B and seventh, unless such application would have an adverse tax consequence for the Borrowers under IRC Section 956, to Obligations of the same type and in the same order as set forth in the preceding clauses “first” through “sixth” of the US Borrowers or Canadian Borrowers as applicable whose Obligations were not covered by such preceding clauses. Neither the Revolving Loan Commitment nor the Swing Line Commitment shall be permanently reduced by the amount of any such prepayments; except to the extent provided pursuant to the terms of Section 1.3(b)(iv).

          (d) Application of Prepayments from Insurance Proceeds and Condemnation Proceeds. Prepayments from insurance or condemnation proceeds in accordance with Section 5.4(c) and insurance or condemnation proceeds from casualties or losses to Equipment, Fixtures and Real Estate, respectively, shall be applied as follows: insurance proceeds from casualties or losses shall be applied first, to the Swing Line Loans and, second, to the Revolving Credit Advances of the Borrower group (either US Borrowers or Canadian Borrowers) encompassing the Borrower that incurred such casualties or losses. Neither the Revolving Loan Commitment nor the Swing Line Loan Commitment shall be permanently reduced by the amount of any such prepayments. If insurance or condemnation proceeds received by a particular Borrower exceed the outstanding principal balances of the Loans to that Borrower group (either US Borrowers or Canadian Borrowers) encompassing the relevant Borrower, those proceeds shall be applied by Agent, (i) in respect of proceeds received by a US Borrower, first to US Obligations, and second to Canadian Obligations; and (ii) in respect of proceeds received by a Canadian Borrower, solely to Canadian Obligations.

          (e) No Implied Consent. Nothing in this Section 1.3 shall be construed to constitute Agent’s or any Lender’s consent to any transaction that is not permitted by other provisions of this Agreement or the other Loan Documents.

          (f) Allocation among US Borrowers and Canadian Borrowers. Notwithstanding anything to the contrary contained herein, subject to Section 1.11, each prepayment required under this Section 1.3 shall be allocated first, to the applicable Obligations of the Borrower group (either US Borrowers or Canadian Borrowers) encompassing the Borrower whose assets gave rise to such prepayment and second, in the case of prepayments by US Borrowers in excess of the US Obligations, such excess shall be applied to the Canadian Obligations, it being understood and agreed that under no circumstances shall any prepayment by the Canadian Borrowers (or any Collateral thereof or the proceeds thereof) be applied to the US Obligations unless, not later than fifteen (15) Business Days prior to any proposed application of any prepayment by the Canadian Borrowers (or any Collateral thereof or the proceeds thereof) to the US Obligations, the Agent notifies the Borrower Representative in writing of its intention to make such application and, if the Borrower Representative believes that such application would have a Negative Effect, the procedures set forth in Section 5.12 with respect to obtaining a tax opinion shall be followed and no such application shall be made unless and until such opinion is delivered. If such opinion states that there will be no Negative Effect as a result of such application or if no such opinion is delivered within 15 days of Agent’s notice to Borrower Representative, such application may be made. The amount of any prepayment shall, in the exercise of Agent’s reasonable discretion, be allocated among individual Borrowers, in each case as appropriate in order to approximately reflect the ownership of the asset as to which such prepayment is made or the existence of the overadvance.

          1.4 Use of Proceeds.

          Borrowers shall utilize the proceeds of the Revolving Loan and the Swing Line Loan for the financing of Borrowers’ ordinary working capital and general corporate needs, including to the extent, and only to the extent, (i) set forth in Section 6.3 to be used by Borrowers to make intercompany loans and advances to Credit Parties which are Guarantors and other

11

Subsidiaries of Borrowers but solely to the extent permitted hereunder, (ii) set forth in Section 6.14, to be used by Borrowers in connection with the repurchase of either Holdings’ publicly traded common Stock or the Subordinated Notes in a transaction consummated in a transaction expressly permitted under Section 6.14 and (iii) set forth in Section 6.1, to be used by Borrowers in connection with the consummation of a Permitted Acquisition consummated in compliance with each of the terms and conditions of Section 6.1.

          1.5 Interest and Applicable Margins.

          (a) US Borrowers shall pay interest to Agent, for the ratable benefit of Lenders in accordance with the various US Loans being made by each US Lender, and Canadian Borrowers shall pay interest to Canadian Agent, for the ratable benefit of Canadian Lenders, in accordance with the various Canadian Loans being made by each Canadian Lender in arrears on each applicable Interest Payment Date, at the following rates: (i) with respect to the Revolving Credit Advances and the Canadian Swing Line Loan, the Index Rate plus the Applicable Revolver Index Margin per annum or, at the election of Borrower Representative, (A) for US Revolving Credit Advances, the applicable LIBOR Rate plus the Applicable Revolver LIBOR Margin per annum, or (B) for Canadian Revolving Credit Advances the Applicable BA Rate plus the Applicable Revolver BA Margin based on the aggregate Revolving Credit Advances outstanding from time to time; (ii) with respect to the Swing Line Loan, at the rate equal to the last month end published rate for 30 day dealer commercial paper (high grade unsecured notes sold through dealers by major corporations in multiples of $1,000) which normally appears in the “Money Rate” column of the Wall Street Journal, plus the Applicable Revolver LIBOR Margin per annum.

          As of the Closing Date, the Applicable Margins are as follows:

Applicable Revolver Index Margin			0.00	%
Applicable Revolver LIBOR Margin			1.25	%
Applicable Revolver BA Margin			1.25	%
Applicable L/C Margin			1.25	%
Applicable Unused Line Fee Margin			.375	%

          The Applicable Margins shall be adjusted (up or down) prospectively as determined by Borrowers’ average daily excess Borrowing Availability for the quarter then ended, commencing with the first day of the first calendar month that occurs more than five (5) days after delivery of Borrowers’ Compliance Certificate to Lenders for the Fiscal Quarter ending December 31, 2005; provided, however, that, notwithstanding the foregoing, within one (1) day of the date that the Indebtedness evidenced by the Subordinated Notes is permanently repaid in full and such Subordinated Notes are repurchased as contemplated hereunder, the Applicable Margins shall be adjusted (up or down) prospectively as determined by Borrowers’ excess Borrowing Availability for such date that the Indebtedness evidenced by the Subordinated Notes is permanently repaid in full and such Subordinated Notes are repurchased as contemplated

hereunder. Adjustments in Applicable Margins will be determined by reference to the following grids:

          (x) For Interest, Letter of Credit Fees and Unused Line Fee:

If Excess Borrowing		Level of
Availability is:		Applicable Margins:
<100,000,000		Level I
<150,000,000, but ³ 100,000,000		Level II
£225,000,000, but ³ 150,000,000		Level III
>225,000,000		Level IV

		Applicable Margins
		Level I				Level II				Level III				Level IV
Applicable Revolver Index Margin			0.500	%			0.250	%			0.000	%			-0.250	%
Applicable Revolver LIBOR Margin			1.750	%			1.500	%			1.250	%			1.000	%
Applicable Revolver BA Margin			1.750	%			1.500	%			1.250	%			1.000	%

Applicable Unused Line Fee Margin			0.250	%			0.250	%			0.375	%			0.375	%

          All adjustments in the Applicable Margins after January 1, 2006 shall be implemented quarterly on a prospective basis, for each calendar month commencing at least 5 days after the date of delivery to Lenders of the quarterly unaudited or annual audited (as applicable) Financial Statements evidencing the need for an adjustment. Concurrently with the delivery of the Compliance Certificate, Borrower Representative shall deliver to Agent and Lenders a certificate, signed by its chief financial officer or treasurer, setting forth in reasonable detail the basis for the continuance of, or any change in, the Applicable Margins. Failure to deliver the Compliance Certificate within 5 days of the required date of delivery shall, in addition to any other remedy provided for in this Agreement, result in an increase in the Applicable Margins to the highest level set forth in the foregoing grid, until the first day of the first calendar month following the delivery of a Compliance Certificate demonstrating that such an increase is not required. If a Default or an Event of Default has occurred and is continuing at the time any reduction in the Applicable Margins is to be implemented, that reduction shall be deferred until the first day of the first calendar month following the date on which such Default or Event of Default is waived or cured.

          (b) If any payment on any Loan becomes due and payable on a day other than a Business Day, the maturity thereof will be extended to the next succeeding Business Day (except as set forth in the definition of LIBOR Period or BA Period) and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension.

          (c) All computations of Fees calculated on a per annum basis and interest shall be made by Agent or Canadian Agent on the basis of a 360-day year, in each case for the actual number of days occurring in the period for which such interest and Fees are payable. The Index Rate is a floating rate determined for each day. Each determination by Agent or Canadian Agent of an interest rate and Fees hereunder shall be final, binding and conclusive on Borrowers, absent manifest error.

          (d) So long as an Event of Default has occurred and is continuing under Section 8.1 (a), (h) or (i), or so long as any other Default or Event of Default has occurred and is continuing and at the election of Agent (or upon the written request of Requisite Lenders) confirmed by written notice from Agent to Borrower Representative, the interest rates applicable to the Loans and the Letter of Credit Fees shall be increased by two percentage points (2%) per annum above the rates of interest or the rate of such Fees otherwise applicable hereunder (“Default Rate”), and all outstanding Obligations shall bear interest at the Default Rate applicable to such Obligations. Interest and Letter of Credit Fees at the Default Rate shall accrue from the initial date of such Default or Event of Default until that Default or Event of Default is cured or waived and shall be payable upon demand.

          (e) Subject to the conditions precedent set forth in Section 2.2, Borrower Representative shall have the option to (i) request that any Revolving Credit Advance be made as a LIBOR Loan or a BA Rate Loan, (ii) convert at any time all or any part of outstanding Loans (other than the Swing Line Loan) from Index Rate Loans to LIBOR Loans or BA Rate Loans, (iii) convert any LIBOR Loan or a BA Rate Loan to an Index Rate Loan, subject to payment of LIBOR breakage costs or BA breakage costs in accordance with Sections 1.13(b) and 1.13(c), respectively if such conversion is made prior to the expiration of the LIBOR Period or BA Period applicable thereto, or (iv) continue all or any portion of any Loan (other than the Swing Line Loan) as a LIBOR Loan or a BA Rate Loan upon the expiration of the applicable LIBOR Period or BA Period and the succeeding LIBOR Period or BA Period of that continued Loan shall commence on the first day after the last day of the LIBOR Period or BA Period of the Loan to be continued. Any Loan or group of Loans having the same proposed LIBOR Period to be made or continued as, or converted into, a LIBOR Loan must be in a minimum amount of $5,000,000 and integral multiples of $1,000,000 in excess of such amount. Any Loan or group of Loans having the same proposed BA Period to be made or continued as, or converted into, a BA Rate Loan must be in a minimum amount of CD1,000,000 and integral multiples of CD500,000 in excess of such amount. Any such election must be made by 12:00 noon (New York time) on the 3rd Business Day prior to (1) the date of any proposed Advance which is to bear interest at the LIBOR Rate or BA Rate, (2) the end of each LIBOR Period with respect to any LIBOR Loans to be continued as such and the end of each BA Period with respect to any BA Rate Loans to be continued as such, or (3) the date on which Borrower Representative wishes to convert any Index Rate Loan to a LIBOR Loan for a LIBOR Period or to a BA Rate Loan for a BA Period designated by Borrower Representative in such election. If no election is received with respect to a LIBOR Loan or BA Rate Loan by 12:00 noon (New York time) on the 3rd Business Day prior to the end of the LIBOR Period or BA Period with respect thereto (or if a Default or an Event of Default has occurred and is continuing or the additional conditions precedent set forth in Section 2.2 shall not have been satisfied), that LIBOR Loan or BA Rate Loan shall be converted to an Index Rate Loan at the end of its LIBOR Period or BA Period respectively. Borrower

Representative must make such election by notice to Agent (and to Canadian Agent if Canadian Loans are involved) in writing, by telecopy or overnight courier. In the case of any conversion or continuation, such election must be made pursuant to a written notice (a “Notice of Conversion/Continuation”) in the form of Exhibit 1.5(e).

          (f) Notwithstanding anything to the contrary set forth in this Section 1.5, if a court of competent jurisdiction determines in a final order that the rate of interest payable hereunder with respect to the US Obligations exceeds the highest rate of interest permissible under applicable law (the “Maximum Lawful Rate”), then so long as the Maximum Lawful Rate would be so exceeded, the rate of interest payable hereunder shall be equal to the Maximum Lawful Rate; provided, however, that if at any time thereafter the rate of interest payable hereunder is less than the Maximum Lawful Rate, US Borrowers shall continue to pay interest hereunder at the applicable Maximum Lawful Rate until such time as the total interest received by Agent, on behalf of Lenders, is equal to the total interest that would have been received had the interest rate payable hereunder been (but for the operation of this paragraph) the interest rate payable since the Closing Date as otherwise provided in this Agreement. Thereafter, interest hereunder shall be paid at the rate(s) of interest and in the manner provided in Sections 1.5(a) through (e), unless and until the rate of interest again exceeds the Maximum Lawful Rate, and at that time this paragraph shall again apply. In no event shall the total interest received by any Lender pursuant to the terms hereof exceed the amount that such Lender could lawfully have received had the interest due hereunder been calculated for the full term hereof at the Maximum Lawful Rate. If the Maximum Lawful Rate is calculated pursuant to this paragraph, such interest shall be calculated at a daily rate equal to the Maximum Lawful Rate divided by the number of days in the year in which such calculation is made. If, notwithstanding the provisions of this Section 1.5(f), a court of competent jurisdiction shall finally determine that a Lender has received interest hereunder in excess of the Maximum Lawful Rate, Agent shall, to the extent permitted by applicable law, promptly apply such excess in the order specified in Section 1.11 and thereafter shall refund any excess to Borrower or as a court of competent jurisdiction may otherwise order.

          (g) If any provision of this Agreement or any of the other Loan Documents would obligate Canadian Borrowers to make any payment of interest under the Canadian Obligations or other amount payable to any Canadian Lender in an amount or calculated at a rate which would be prohibited by law or would result in a receipt by that Canadian Lender of interest with respect to the Canadian Obligations at a criminal rate (as such term is construed under the Criminal Code (Canada)) then, notwithstanding such provision, such amount or rates shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by law or so result in a receipt by that Canadian Lender of interest with respect to the Canadian Obligations at a criminal rate, such adjustment to be effected, to the extent necessary, as follows: (1) firstly, by reducing the amount or rates of interest required to be paid to the affected Canadian Lenders under this Section 1.5; and (2) thereafter, by reducing any fees, commissions, premiums and other amounts required to be paid to the affected Canadian Lender which would constitute interest under the Canadian Obligations for purposes of Section 347 of the Criminal Code (Canada). Notwithstanding the foregoing, and after giving effect to all adjustments contemplated thereby, if any Canadian Lender shall have received an amount in excess of the maximum permitted by that section of the

Criminal Code (Canada), then Canadian Borrowers shall be entitled, by notice in writing to the affected Canadian Lender, to obtain reimbursement from that Canadian Lender in an amount equal to such excess, and pending such reimbursement, such amount shall be deemed to be an amount payable by that Canadian Lender to Canadian Borrowers. Any amount or rate of interest with respect to the Canadian Obligations referred to in this Section 1.5(g) shall be determined in accordance with generally accepted actuarial practices and principles as an effective annual rate of interest over the term that any Canadian Loan remains outstanding on the assumption that any charges, fees or expenses that fall within the meaning of “interest” (as defined in the Criminal Code (Canada)) shall, if they relate to a specific period of time, be pro-rated over that period of time and otherwise be pro-rated over the period from the Closing Date to the Termination Date (with reference to the Canadian Obligations) and, in the event of a dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by Canadian Agent shall be conclusive for the purposes of such determination.

          (h) Interest Act (Canada). For purposes of disclosure pursuant to the Interest Act (Canada), the annual rates of interest or fees to which the rates of interest or fees provided in this Agreement and the other Loan Documents for the Canadian Obligations (as stated herein or therein, as applicable, to be computed on the basis of a 360 or 365 day year or any other period of time less than a calendar year) are equivalent to the rates so determined multiplied by the actual number of days in the applicable calendar year and divided by 360, 365 or such other period of time, respectively.

          1.6 Eligible Accounts.

          All of the Accounts owned by WESCO DC LP and reflected in the most recent Borrowing Base Certificate delivered by Borrower Representative on behalf of the applicable Borrower Group (i.e., US Borrowers or Canadian Borrowers) to Agent shall be “Eligible Accounts” for purposes of this Agreement, except any Account to which any of the exclusionary criteria set forth below applies. Agent shall have the right to establish, modify or eliminate Reserves against Eligible Accounts from time to time in its reasonable credit judgment. In addition, Agent reserves the right, at any time and from time to time after the Closing Date, to adjust any of the criteria set forth below, to establish new criteria and to adjust advance rates with respect to Eligible Accounts, in its reasonable credit judgment, subject to the approval of Supermajority Lenders in the case of adjustments, new criteria, or changes in advance rates or the elimination of Reserves imposed as of the Closing Date which have the effect of making more credit available (it being understood that Agent may in its reasonable credit judgment eliminate Reserves established by it in its reasonable credit judgment after the Closing Date without the necessity of obtaining the approval of Supermajority Lenders or Requisite Lenders). Borrowers and the other Credit Parties hereby acknowledge and agree that only Accounts owned by WESCO DC LP, and no Accounts owned by any other Borrower or any other Credit Party, may constitute Eligible Accounts. Eligible Accounts shall not include any Account of WESCO DC LP:

          (ii) As additional compensation for the Canadian Lenders, Canadian Borrowers shall pay to Canadian Agent, for the ratable benefit of Canadian Lenders, in arrears, on the first Business Day of each month prior to the Commitment Termination Date and on the Commitment Termination Date, a Fee for Canadian Borrowers’ non-use of available funds in an amount equal to the Applicable Unused Line Fee Margin per annum (calculated on the basis of a 360 day year for actual days elapsed) multiplied by the difference between (x) the Maximum Canadian Amount (as it may be reduced from time to time) and (y) the average for the period of

the daily closing balances of the aggregate Canadian Revolving Credit Advances and the Canadian Swing Line Advances outstanding during the period for which such Fee is due.

     (d) US Borrowers shall pay to Agent, for the ratable benefit of US Lenders, the Letter of Credit Fee, in respect of US Letters of Credit as provided in Annex B, and Canadian Borrowers shall pay to Canadian Agent, for the ratable benefit of Canadian Lenders, the Letter of Credit Fee in respect of Canadian Letters of Credit as provided in Annex B.

     1.10 Receipt of Payments.

     US Borrowers shall make each payment under this Agreement not later than 2:30 p.m. (New York time) on the day when due in immediately available funds in Dollars to the US Collection Account. Canadian Borrowers shall make each payment under this Agreement not later than 2:30 p.m. (New York time) on the day when due in immediately available funds in Canadian Dollars to the Canadian Collection Account. For purposes of computing interest and Fees and determining Borrowing Availability as of any date, all payments shall be deemed received on the Business Day on which immediately available funds therefor are received in the applicable Collection Account prior to 2:30 p.m. (New York time). Payments received after 2:30 p.m. New York time on any Business Day or on a day that is not a Business Day shall be deemed to have been received on the following Business Day. If Agent receives any payment from or on behalf of any Credit Party in a currency other than the currency in which an Obligation payable is denominated, Agent may convert the payment (including the monetary proceeds of realization upon any Collateral and any funds then held in a cash collateral account) into Dollars at the exchange rate that Agent would be prepared to sell the currency received in New York, New York on the Business Day immediately preceding the date of actual payment. The Obligations shall be satisfied only to the extent of the amount actually received by Agent upon such conversion.

     1.11 Application and Allocation of Payments.

     (a) So long as no Default or Event of Default has occurred and is continuing, (i) payments consisting of proceeds of Accounts or Inventory received in the ordinary course of business shall be applied, in the case of receipt by or on behalf of any US Borrower, first, to the US Swing Line Loan and, second, to the US Revolving Loan, and, in the case of receipt by or on behalf of any Canadian Borrower, first to the Canadian Swing Line Advances and, second, to the Canadian Revolving Loan; (ii) payments matching specific scheduled payments then due shall be applied to those scheduled payments; (iii) voluntary prepayments shall be applied as determined by Borrower, subject to the provisions of Section 1.3(a); and (iv) mandatory prepayments shall be applied as set forth in Sections 1.3(b), (c), (d) and (f). All payments and prepayments applied to a particular Loan shall be applied ratably to the portion thereof held by each US Lender as determined by its Pro Rata Share thereof and held by each Canadian Lender as determined by its Pro Rata Share thereof. As to any other payment, and as to all payments made when a Default or Event or Default has occurred and is continuing or following the Commitment Termination Date, Borrowers hereby irrevocably waive the right to direct the application of any and all payments received from or on behalf of Borrowers, and Borrowers hereby irrevocably agree that Agent shall have the continuing exclusive right to apply any and all such payments in respect of the

Obligations then due and payable in the following order: (1) to Fees and Agents’ expenses reimbursable hereunder; (2) to interest on the Swing Line Loan; (3) to principal payments on the Swing Line Loan; (4) to interest on the Revolving Loan; (5) to principal payments on the Revolving Loan; (6) to provide cash collateral for Letter of Credit Obligations in the manner described in Annex B and (7) to all other Obligations including expenses of Lenders to the extent reimbursable under Section 11.3; provided, however, that in no event shall any such payments applicable to a Canadian Borrower or other Canadian Credit Party be applied to any US Obligations.

     (b) The Applicable Agent is authorized to, and at its sole election may, charge to the Revolving Loan balance on behalf of Borrowers under the applicable Facilities and cause to be paid all Fees, expenses, Charges, costs (including insurance premiums in accordance with Section 5.4(a)) and interest and principal, other than principal of the Revolving Loan under the applicable Facilities, owing by the applicable Borrower under this Agreement or any of the other Loan Documents if and to the extent such Borrowers fail to pay promptly any such amounts as and when due, even if the amount of such charges would exceed Borrowing Availability at such time. At the Applicable Agent’s option and to the extent permitted by law, any charges so made shall constitute part of the Revolving Loan under the applicable Facilities hereunder to which such charges relate.

     1.12 Loan Account and Accounting.

     Each Agent shall maintain a loan account (the “US Loan Account”, in the case of such account maintained by the Agent, and the “Canadian Loan Account”, in the case of such account maintained by the Canadian Agent, and “Loan Account” means either or both of them, as the context permits) on its books to record: all Advances, all payments made by Borrowers, and all other debits and credits as provided in this Agreement with respect to the Loans or any other Obligations, in each case, relating to the applicable Facilities being administered by the Applicable Agent. All entries in the applicable Loan Account shall be made in accordance with the Applicable Agent’s customary accounting practices as in effect from time to time. The balance in the Loan Account, as recorded on Agent’s most recent printout or other written statement, shall, absent demonstrable error, be presumptive evidence of the amounts due and owing to the Agent and US Lenders by US Borrowers, in the case of the US Loan Account, and to the Canadian Agent and the Canadian Lenders, in the case of the Canadian Loan Account; provided that any failure to so record or any error in so recording shall not limit or otherwise affect the applicable Borrower’s duty to pay the Obligations. Each Agent shall render to Borrower Representative a monthly accounting of transactions with respect to the US Loans and Canadian Loans setting forth the balance of the US Loan Account and the Canadian Loan Account for the immediately preceding month. Unless Borrower Representative notifies Agent in writing of any objection to any such accounting (specifically describing the basis for such objection), within 30 days after the date thereof, each and every such accounting shall, absent demonstrable error, be deemed final, binding and conclusive on Borrower(s) in all respects as to all matters reflected therein. Only those items expressly objected to in such notice shall be deemed to be disputed by the applicable Borrower(s). Notwithstanding any provision herein contained to the contrary, any Lender may elect (which election may be revoked) to dispense

with the issuance of Notes to that Lender and may rely on the applicable Loan Account as evidence of the amount of Obligations from time to time owing to it.

     1.13 Indemnity.

     (a) Each Credit Party that is a signatory hereto shall jointly and severally indemnify and hold harmless each Agent, Lenders and their respective Affiliates, and each such Person’s respective officers, directors, employees, attorneys, agents and representatives (each, an “Indemnified Person”), from and against any and all suits, actions, proceedings, claims, damages, losses, liabilities and expenses (including reasonable attorneys’ fees and disbursements and other costs of investigation or defense, including those incurred upon any appeal) that may be instituted or asserted against or incurred by any such Indemnified Person as the result of credit having been extended, suspended or terminated under this Agreement and the other Loan Documents and the administration of such credit, and in connection with or arising out of the transactions contemplated hereunder and thereunder and any actions or failures to act in connection therewith, including any and all Environmental Liabilities and legal costs and expenses arising out of or incurred in connection with disputes between or among any parties to any of the Loan Documents (collectively, “Indemnified Liabilities”); provided, that no such Credit Party shall be liable for any indemnification to an Indemnified Person to the extent that any such suit, action, proceeding, claim, damage, loss, liability or expense results from that Indemnified Person’s gross negligence or willful misconduct. NO INDEMNIFIED PERSON SHALL BE RESPONSIBLE OR LIABLE TO ANY OTHER PARTY TO ANY LOAN DOCUMENT, ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY BENEFICIARY OF SUCH PERSON OR ANY OTHER PERSON ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN EXTENDED, SUSPENDED OR TERMINATED UNDER ANY LOAN DOCUMENT OR AS A RESULT OF ANY OTHER TRANSACTION CONTEMPLATED HEREUNDER OR THEREUNDER.

     (b) To induce Lenders to provide the LIBOR Rate option on the terms provided herein, if (i) any LIBOR Loans are repaid in whole or in part prior to the last day of any applicable LIBOR Period (whether that repayment is made pursuant to any provision of this Agreement or any other Loan Document or occurs as a result of acceleration, by operation of law or otherwise); (ii) any Borrower shall default in payment when due of the principal amount of or interest on any LIBOR Loan; (iii) any Borrower shall refuse to accept any borrowing of, or shall request a termination of any borrowing, conversion into or continuation of LIBOR Loans after Borrower Representative has given notice requesting the same in accordance herewith; or (iv) any Borrower shall fail to make any prepayment of a LIBOR Loan after Borrower Representative has given a notice thereof in accordance herewith, then Borrowers shall jointly and severally indemnify and hold harmless each Lender from and against all losses, costs and expenses resulting from or arising from any of the foregoing provided that the Canadian Borrowers shall be obligated to indemnify any Lender with respect to only such losses, costs and expenses in respect of the Canadian Obligations. Such indemnification shall include any loss (including loss of margin) or expense arising from the reemployment of funds obtained by it or from fees payable to terminate deposits from which such funds were obtained. For the purpose of

calculating amounts payable to a Lender under this subsection, each Lender shall be deemed to have actually funded its relevant LIBOR Loan through the purchase of a deposit bearing interest at the LIBOR Rate in an amount equal to the amount of that LIBOR Loan and having a maturity comparable to the relevant LIBOR Period; provided, that each Lender may fund each of its LIBOR Loans in any manner it sees fit, and the foregoing assumption shall be utilized only for the calculation of amounts payable under this subsection. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. As promptly as practicable under the circumstances, each Lender shall provide Borrower Representative with its written calculation of all amounts payable pursuant to this Section 1.13(b), and such calculation shall be binding on the parties hereto unless Borrower Representative shall object in writing within 10 Business Days of receipt thereof, specifying the basis for such objection in detail.

     (c) To induce Lenders to provide the BA Rate option on the terms provided herein, if (i) any BA Rate Loans are repaid in whole or in part prior to the last day of any applicable BA Period (whether that repayment is made pursuant to any provision of this Agreement or any other Loan Document or occurs as a result of acceleration, by operation of law or otherwise); (ii) any Borrower shall default in payment when due of the principal amount of or interest on any BA Rate Loan; (iii) any Canadian Borrower shall refuse to accept any borrowing of, or shall request a termination of, any borrowing of, conversion into or continuation of, BA Rate Loans after Borrower Representative has given notice requesting the same in accordance herewith; or (iv) any Canadian Borrower shall fail to make any prepayment of a BA Rate Loan after Borrower Representative has given a notice thereof in accordance herewith, then Borrowers shall jointly and severally indemnify and hold harmless each Lender from and against all losses, costs and expenses resulting from or arising from any of the foregoing. Such indemnification shall include any loss (including loss of margin) or expense arising from the reemployment of funds obtained by it or from fees payable to terminate deposits from which such funds were obtained. For the purpose of calculating amounts payable to a Lender under this subsection, each Lender shall be deemed to have actually funded its relevant BA Rate Loan through the purchase of a deposit bearing interest at the BA Rate in an amount equal to the amount of that BA Rate Loan and having a maturity comparable to the relevant BA Period; provided, that each Lender may fund each of its BA Rate Loans in any manner it sees fit, and the foregoing assumption shall be utilized only for the calculation of amounts payable under this subsection. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. As promptly as practicable under the circumstances, each Lender shall provide Borrower Representative with its written calculation of all amounts payable pursuant to this Section 1.13(c), and such calculation shall be binding on the parties hereto unless Borrower Representative shall object in writing within ten (10) Business Days of receipt thereof, specifying the basis for such objection in detail.

     1.14 Access.

     Each Credit Party that is a party hereto shall, during normal business hours, from time to time upon three (3) Business Day’s prior notice to the Borrower Representative (attention: Treasurer); provided, however, that after the occurrence and during the continuance of a Default or Event of Default, no such prior notice shall be required; as frequently as each

Agent determines to be appropriate; (a) provide each Agent and any of its officers, employees and agents access to its properties, facilities, advisors and employees (including officers) of each Credit Party and to the Collateral, (b) permit each Agent, and any of its officers, employees and agents, to inspect, audit and make extracts from any Credit Party’s books and records, and (c) permit each Agent, and its officers, employees and agents, to inspect, review, evaluate and make test verifications and counts of the Accounts and Inventory of any Credit Party and other Collateral of any Credit Party. Absent a Default or Event of Default, Borrowers shall not be required to pay for (i) more than one (1) inventory appraisal per year or (ii) more than two (2) collateral audits per year. If a Default or Event of Default has occurred and is continuing or if access is necessary to preserve or protect the Collateral as determined by the Agent, in its reasonable credit judgment, each such Credit Party shall provide such access to Agent and Canadian Agent and to each Lender at all times and without advance notice at Borrowers’ expense. Furthermore, so long as any Event of Default has occurred and is continuing, Borrowers shall provide Agent and Canadian Agent and each Lender with access to its suppliers and customers. Each Credit Party shall make available to Agent and Canadian Agent and its counsel, as quickly as is possible under the circumstances, originals or copies of all books and records that such Agent may reasonably request. Each Credit Party shall deliver any document or instrument necessary for Agent and Canadian Agent, as it may from time to time request, to obtain records from any service bureau or other Person that maintains records for such Credit Party, and shall maintain duplicate records or supporting documentation on media, including computer tapes and discs owned by such Credit Party. Each Agent will give Lenders at least 5 days’ prior written notice of regularly scheduled audits. Representatives of other Lenders may accompany Agent’s or Canadian Agent’s representatives on regularly scheduled audits at no charge to Borrowers.

     1.15 Taxes.

     (a) Any and all payments by each Borrower hereunder (including any payments made pursuant to Section 12) or under the Notes shall be made, in accordance with this Section 1.15, free and clear of and without deduction for any and all present or future Taxes. If any Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder (including any payments made pursuant to Section 12) or under the Notes, (i) the sum payable shall be increased as much as shall be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 1.15) Agent or Canadian Agent or Lenders, as applicable, receive an amount equal to the sum they would have received had no such deductions been made, (ii) such Borrower shall make such deductions, and (iii) such Borrower shall pay the full amount deducted to the relevant taxing or other authority in accordance with applicable law. Within 30 days after the date of any payment of Taxes, Borrower Representative shall furnish to Agent the original or a certified copy of a receipt evidencing payment thereof. Agent, Canadian Agent and Lenders shall not be obligated to return or refund any amounts received pursuant to this Section.

     (b) Each Credit Party that is a signatory hereto shall jointly and severally indemnify and, within 10 days of demand therefor, pay Agent and Canadian Agent and each Lender for the full amount of Taxes (including any Taxes imposed by any jurisdiction on amounts payable under this Section 1.15) paid by Agent or Canadian Agent or such Lender, as

appropriate, and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally asserted.

     (c) Each US Lender organized under the laws of a jurisdiction outside the United States (a “Foreign Lender”) as to which payments to be made under this Agreement or under the Notes are exempt from United States withholding tax under an applicable statute or tax treaty shall provide to Borrower Representative and Agent a properly completed and executed IRS Form W-8ECI or Form W-8BEN or other applicable form, certificate or document prescribed by the IRS or the United States certifying as to such Foreign Lender’s entitlement to such exemption (a “Certificate of Exemption”). Any foreign Person that seeks to become a US Lender under this Agreement shall provide a Certificate of Exemption to Borrower Representative and Agent prior to becoming a US Lender hereunder. No foreign Person may become a US Lender hereunder if such Person fails to deliver a Certificate of Exemption in advance of becoming a Lender.

     1.16 Capital Adequacy; Increased Costs; Illegality.

     (a) If any Lender shall have determined that any law, treaty, governmental (or quasi-governmental) rule, regulation, guideline or order regarding capital adequacy, reserve requirements or similar requirements or compliance by any Lender with any request or directive regarding capital adequacy, reserve requirements or similar requirements (whether or not having the force of law), in each case, adopted after the Closing Date, from any central bank or other Governmental Authority increases or would have the effect of increasing the amount of capital, reserves or other funds required to be maintained by such Lender and thereby reducing the rate of return on such Lender’s capital as a consequence of its obligations hereunder, then Borrowers shall from time to time upon demand by such Lender (with a copy of such demand to the Applicable Agent) pay to such Agent, for the account of such Lender, additional amounts sufficient to compensate such Lender for such reduction. A certificate as to the amount of that reduction and showing the basis of the computation thereof submitted by such Lender to Borrower Representative and to such Agent shall, absent manifest error, be final, conclusive and binding for all purposes.

     (b) If, due to either (i) the introduction of or any change in any law or regulation (or any change in the interpretation thereof) or (ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), in each case adopted after the Closing Date, there shall be any increase in the cost to any Lender of agreeing to make or making, funding or maintaining any Loan, then Borrowers shall from time to time, upon demand by such Lender (with a copy of such demand to Agent), pay to Agent (or Canadian Agent if in respect of Canadian Loans) for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the amount of such increased cost, submitted to Borrower Representative and to Agent by such Lender, shall be conclusive and binding on Borrower for all purposes, absent manifest error. Each Lender agrees that, as promptly as practicable after it becomes aware of any circumstances referred to above which would result in any such increased cost, the affected Lender shall, to the extent not inconsistent with such Lender’s internal policies of general application, use reasonable

commercial efforts to minimize costs and expenses incurred by it and payable to it by Borrowers pursuant to this Section 1.16(b).

     (c) Notwithstanding anything to the contrary contained herein, if the introduction of or any change in any law or regulation (or any change in the interpretation thereof) shall make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful, for any Lender to agree to make or to make or to continue to fund or maintain any LIBOR Loan, then, unless that Lender is able to make or to continue to fund or to maintain such LIBOR Loan at another branch or office of that Lender without, in that Lender’s opinion, adversely affecting it or its Loans or the income obtained therefrom, on notice thereof and demand therefor by such Lender to Borrower Representative through Agent, (i) the obligation of such Lender to agree to make or to make or to continue to fund or maintain LIBOR Loans shall terminate and (ii) each Borrower shall forthwith prepay in full all outstanding LIBOR Loans owing by such Borrower to such Lender, together with interest accrued thereon, unless Borrower Representative, on behalf of such Borrower, within 5 Business Days after the delivery of such notice and demand, converts all LIBOR Loans into Index Rate Loans.

     (d) Within 15 days after receipt by Borrower Representative of written notice and demand from any Lender (an “Affected Lender”) for payment of additional amounts or increased costs as provided in Sections 1.15(a), 1.16(a) or 1.16(b), Borrower Representative may, at its option, notify Agent and such Affected Lender of its intention to replace the Affected Lender. So long as no Default or Event of Default has occurred and is continuing, Borrower Representative, with the consent of Agent, may obtain, at Borrowers’ expense, a replacement Lender (“Replacement Lender”) for the Affected Lender, which Replacement Lender must be reasonably satisfactory to Agent. If Borrowers obtain a Replacement Lender within 90 days following notice of their intention to do so, the Affected Lender must sell and assign its Loans and Commitments to such Replacement Lender for an amount equal to the principal balance of all Loans held by the Affected Lender and all accrued interest and Fees with respect thereto through the date of such sale; provided, that Borrowers shall have reimbursed such Affected Lender for the additional amounts or increased costs that it is entitled to receive under this Agreement through the date of such sale and assignment. Notwithstanding the foregoing, Borrowers shall not have the right to obtain a Replacement Lender if the Affected Lender rescinds its demand for increased costs or additional amounts within 15 days following its receipt of Borrowers’ notice of intention to replace such Affected Lender. Furthermore, if Borrowers give a notice of intention to replace and do not so replace such Affected Lender within 90 days thereafter, Borrowers’ rights under this Section 1.16(d) shall terminate and Borrowers shall promptly pay all increased costs or additional amounts demanded by such Affected Lender pursuant to Sections 1.15(a), 1.16(a) and 1.16(b).

     1.17 Single Loan.

     All Loans to each US Borrower and all of the other Obligations of each US Borrower arising under this Agreement and the other Loan Documents shall constitute one general obligation of that Borrower secured, until the Termination Date, by all of the Collateral of the US Borrowers. All Loans to each Canadian Borrower and all of the other Obligations of each Canadian Borrower arising under this Agreement and the other Loan Documents shall

constitute one general obligation of that Borrower secured, until the Termination Date, by all of the Collateral held by the Canadian Borrowers and all of the Collateral held by the US Borrowers.

     (a) any representation or warranty by any Credit Party contained herein or in any other Loan Document is untrue or incorrect as of such date, except to the extent that such representation or warranty expressly relates to an earlier date and except for changes therein expressly permitted or expressly contemplated by this Agreement, and Agent or Requisite Lenders have determined not to make such Advance, convert or continue any Loan as LIBOR Loan or BA Rate Loan or incur such Letter of Credit Obligation as a result of the fact that such warranty or representation is untrue or incorrect;

No Credit Party is subject to regulation under the Public Utility Holding Company Act of 1935, the Federal Power Act, or any other federal or state statute that restricts or limits its ability to incur Indebtedness or to perform its obligations hereunder. The making of the Loans by Lenders to Borrowers, the incurrence of the Letter of Credit Obligations on behalf of Borrowers, the application of the proceeds thereof and repayment thereof and the consummation of the Related Transactions will not violate any provision of any

such statute or any rule, regulation or order issued by the Securities and Exchange Commission (or applicable foreign equivalent or similar regulatory body).

     3.10 Margin Regulations.

     No Credit Party is engaged, nor will it engage, principally or as one of its important activities, in the business of extending credit for the purpose of “purchasing” or “carrying” any “margin stock” as such terms are defined in Regulation U of the Federal Reserve Board as now and from time to time hereafter in effect (such securities being referred to herein as “Margin Stock”). No Credit Party owns any Margin Stock, and none of the proceeds of the Loans or other extensions of credit under this Agreement will be used, directly or indirectly, for the purpose of purchasing or carrying any Margin Stock, for the purpose of reducing or retiring any Indebtedness that was originally incurred to purchase or carry any Margin Stock or for any other purpose that might cause any of the Loans or other extensions of credit under this Agreement to be considered a “purpose credit” within the meaning of Regulations T, U or X of the Federal Reserve Board. No Credit Party will take or permit to be taken any action that might cause any Loan Document to violate any regulation of the Federal Reserve Board.

     3.11 Taxes.

     All tax returns, reports and statements, including information returns, required by any Governmental Authority to be filed by any Credit Party have been filed with the appropriate Governmental Authority and all Charges have been paid prior to the date on which any fine, penalty, interest or late charge may be added thereto for nonpayment thereof (or any such fine, penalty, interest, late charge or loss has been paid), excluding Charges or other amounts being contested in accordance with Section 5.2(b).

Disclosure Schedule (3.11) sets forth as of the Closing Date those taxable years for which any Credit Party’s tax returns are currently being audited by the IRS or any other applicable Governmental Authority and any assessments or threatened assessments in connection with such audit, or otherwise currently outstanding. Except as described in Disclosure Schedule (3.11), no Credit Party has executed or filed with the IRS or any other Governmental Authority any agreement or other document extending, or having the effect of extending, the period for assessment or collection of any Charges. None of the Credit Parties and their respective predecessors are liable for any Charges: (a) under any agreement (including any tax sharing agreements) or (b) to each Credit Party’s knowledge, as a transferee. As of the Closing Date, no Credit Party has agreed or been requested to make any adjustment under IRC Section 481(a), by reason of a change in accounting method or otherwise, which would have a Material Adverse Effect.

     3.12 ERISA.

     (a) Disclosure Schedule (3.12) lists all Plans and separately identifies all Pension Plans, including Title IV Plans, Multiemployer Plans, ESOPs and Welfare Plans, including all Retiree Welfare Plans. Copies of all such listed Plans, together with a copy of the

latest IRS/DOL form 5500-series for each such Plan, if applicable, have been delivered to Agent. Except with respect to Multiemployer Plans, each Qualified Plan has been determined by the IRS to qualify under Section 401 of the IRC, the trusts created thereunder have been determined to be exempt from tax under the provisions of Section 501 of the IRC, and nothing has occurred that would cause the loss of such qualification or tax-exempt status. Each Plan is in material compliance with the applicable provisions of ERISA and the IRC, including the timely filing of all reports required under the IRC or ERISA, including the statement required by 29 CFR Section 2520.104-23. Neither any Credit Party nor ERISA Affiliate has failed to make any contribution or pay any amount due as required by either Section 412 of the IRC or Section 302 of ERISA or the terms of any such Plan. Neither any Credit Party nor ERISA Affiliate has engaged in a “prohibited transaction,” as defined in Section 406 of ERISA and Section 4975 of the IRC, in connection with any Plan, that would subject any Credit Party to a material tax on prohibited transactions imposed by Section 502(i) of ERISA or Section 4975 of the IRC.

     (b) Except as set forth in Disclosure Schedule (3.12): (i) no Title IV Plan has any Unfunded Pension Liability; (ii) no ERISA Event or event described in Section 4062(e) of ERISA with respect to any Title IV Plan has occurred or is reasonably expected to occur; (iii) there are no pending, or to the knowledge of any Credit Party, threatened claims (other than claims for benefits in the normal course), sanctions, actions or lawsuits, asserted or instituted against any Plan or any Person as fiduciary or sponsor of any Plan; (iv) no Credit Party or ERISA Affiliate has incurred or reasonably expects to incur any liability as a result of a complete or partial withdrawal from a Multiemployer Plan; (v) within the last five years no Title IV Plan of any Credit Party or ERISA Affiliate has been terminated, whether or not in a “standard termination” as that term is used in Section 404(b)(1) of ERISA, nor has any Title IV Plan of any Credit Party or ERISA Affiliate (determined at any time within the past five years) with Unfunded Pension Liabilities been transferred outside of the “controlled group” (within the meaning of Section 4001(a)(14) of ERISA) of any Credit Party or ERISA Affiliate; (vi) except in the case of any ESOP, Stock of all Credit Parties and their ERISA Affiliates makes up, in the aggregate, no more than 10% of fair market value of the assets of any Plan measured on the basis of fair market value as of the latest valuation date of any Plan; and (vii) no liability under any Title IV Plan has been satisfied with the purchase of a contract from an insurance company that is not rated AAA by the Standard & Poor’s Corporation or an equivalent rating by another nationally recognized rating agency. The Canadian Pension Plans are duly registered under the ITA and all other applicable laws which require registration and no event has occurred which is reasonably likely to cause the loss of such registered status. All obligations of WESCO DC LP (including fiduciary, funding, investment and administration obligations) required to be performed in connection with the Canadian Pension Plans and the funding agreements therefor have been performed in a timely fashion. There have been no improper withdrawals or applications of the assets of the Canadian Pension Plans or the Canadian Benefit Plans. There are no outstanding material disputes concerning the assets of the Canadian Pension Plans or the Canadian Benefit Plans. Each of the Canadian Pension Plans is fully funded on a solvency basis (using actuarial methods and assumptions which are consistent with the valuations last filed with the applicable Governmental Authorities and which are consistent with generally accepted actuarial principles). Disclosure Schedule (3.12) lists all Canadian Benefit Plans and Canadian Pension Plans adopted by any Credit Party.

     3.13 No Litigation.

     No action, claim, lawsuit, demand, investigation or proceeding is now pending or, to the knowledge of any Credit Party, threatened against any Credit Party, before any Governmental Authority or before any arbitrator or panel of arbitrators (collectively, “Litigation”), (a) that challenges any Credit Party’s right or power to enter into or perform any of its obligations under the Loan Documents to which it is a party, or the validity or enforceability of any Loan Document or any action taken thereunder, or (b) that has a reasonable risk of being determined adversely to any Credit Party and that, if so determined, could reasonably be expected to have a Material Adverse Effect. Except as set forth on Disclosure Schedule (3.13), as of the Closing Date there is no Litigation pending or threatened that seeks damages in excess of $500,000 or injunctive relief against, or alleges criminal misconduct of, any Credit Party.

     3.14 Brokers.

     No broker or finder acting on behalf of any Credit Party or Affiliate thereof brought about the obtaining, making or closing of the Loans or the Related Transactions, and no Credit Party or Affiliate thereof has any obligation to any Person in respect of any finder’s or brokerage fees in connection therewith.

     3.15 Intellectual Property.

     As of the Closing Date, each Credit Party owns or has rights to use all Intellectual Property necessary to continue to conduct its business as now or heretofore conducted by it or proposed to be conducted by it, and each Patent, Design, Trademark, Copyright and License is listed, together with application or registration numbers, as applicable, in Disclosure Schedule (3.15). Each Credit Party conducts its business and affairs without infringement of or interference with any Intellectual Property of any other Person in any material respect. Except as set forth in Disclosure Schedule (3.15), no Credit Party is aware of any infringement claim by any other Person with respect to any Intellectual Property.

     3.16 Full Disclosure.

     No information contained in this Agreement, any of the other Loan Documents, any Projections, Financial Statements or Collateral Reports or other written reports from time to time delivered hereunder or any written statement furnished by or on behalf of any Credit Party to either Agent or any Lender pursuant to the terms of this Agreement contains or will contain any untrue statement of a material fact or omits or will omit to state a material fact necessary to make the statements contained herein or therein not misleading in light of the circumstances under which they were made.

     (a) The Credit Parties shall, at their sole cost and expense, maintain the policies of insurance described on Disclosure Schedule (3.18) as in effect on the date hereof or otherwise in form and amounts and with insurers reasonably acceptable to Agent. Such policies of insurance (or the loss payable and additional insured endorsements delivered to Agent) shall contain provisions pursuant to which the insurer agrees to provide 30 days prior written notice to the Applicable Agent in the event of any non-renewal, cancellation or amendment of any such insurance policy. If any Credit Party at any time or times hereafter shall fail to obtain or maintain any of the policies of insurance required above or to pay all premiums relating thereto, the Applicable Agent may at any time or times thereafter obtain and maintain such policies of insurance and pay such premiums and take any other action with respect thereto that Agent deems advisable. Neither Agent shall have any obligation to obtain insurance for any Credit Party or pay any premiums therefor. By doing so, neither Agent shall be deemed to have waived any Default or Event of Default arising from any Credit Party’s failure to maintain such insurance or pay any premiums therefor. All sums so disbursed, including reasonable attorneys’

fees, court costs and other charges related thereto, shall be payable on demand by Borrowers to the Applicable Agent and shall be additional Obligations hereunder secured by the Collateral.

     (b) Each Agent reserves the right at any time upon any change in any Credit Party’s risk profile (including any change in the product mix maintained by any Credit Party or any laws affecting the potential liability of such Credit Party) to require additional forms and limits of insurance to, in Agent’s opinion, adequately protect both such Agent’s and Lender’s interests in all or any portion of the Collateral and to ensure that each Credit Party is protected by insurance in amounts and with coverage customary for its industry. If reasonably requested by either Agent, each Credit Party shall deliver to such Agent from time to time a report of a reputable insurance broker, selected by Borrowers and reasonably satisfactory to such Agent, with respect to its insurance policies.

     (c) Each Credit Party shall deliver to each Applicable Agent, in form and substance reasonably satisfactory to such Agent, endorsements to (i) all “All Risk” and business interruption insurance naming such Agent, on behalf of itself, the other Agent, as applicable, for whom it acts as agent and those Lenders for whom it acts as agent, as loss payee, to the extent such Agent or the other Agent or Lenders for whom it acts as agent has an interest in the Collateral covered thereby and (ii) all general liability and other liability policies naming each Applicable Agent, on behalf of itself, the other Agent, as applicable, and those Lenders for whom it acts as agent, as additional insured. Each Credit Party irrevocably makes, constitutes and appoints each Applicable Agent (and all officers, employees or agents designated by such Agent), so long as any Default or Event of Default has occurred and is continuing or the anticipated insurance proceeds exceed $1,000,000, as each Credit Party’s true and lawful agent and attorney-in-fact for the purpose of making, settling and adjusting claims under such “All Risk” policies of insurance, endorsing the name of each Credit Party on any check or other item of payment for the proceeds of such “All Risk” policies of insurance and for making all determinations and decisions with respect to such “All Risk” policies of insurance. Agent shall have no duty to exercise any rights or powers granted to it pursuant to the foregoing power-of-attorney. Borrower Representative shall promptly notify each Agent of any loss, damage, or destruction to the Collateral in the amount of $500,000 or more, whether or not covered by insurance. After deducting from such proceeds the expenses, if any, incurred by each Agent in the collection or handling thereof, each Applicable Agent may, at its option, apply such proceeds to the reduction of the Obligations in accordance with Section 1.3(d), provided that in the case of insurance proceeds pertaining to any Credit Party other than any Borrower, such insurance proceeds shall be applied ratably to all of the US Loans, in the case of a US Credit Party, and to all of the Canadian Loans, in the case of a Canadian Credit Party, or permit or require each Credit Party to use such money, or any part thereof, to replace, repair, restore or rebuild the Collateral in a diligent and expeditious manner with materials and workmanship of substantially the same quality as existed before the loss, damage or destruction. Notwithstanding the foregoing, if the casualty giving rise to such insurance proceeds could not reasonably be expected to have a Material Adverse Effect and such insurance proceeds do not exceed $1,000,000 in the aggregate, the Applicable Agent shall permit the applicable Credit Party to replace, restore, repair or rebuild the property; provided that if such Credit Party has not completed or entered into binding agreements to complete such replacement, restoration, repair or rebuilding within 180 days of such casualty, the Applicable Agent may apply such insurance proceeds to the Obligations in

accordance with Section 1.3(d); provided further that in the case of insurance proceeds pertaining to any Credit Party other than a Borrower, such insurance proceeds shall be applied to the Loans owing by Borrowers. All insurance proceeds that are to be made available to any Borrower to replace, repair, restore or rebuild the Collateral shall be applied by the Applicable Agent to reduce the outstanding principal balance of the applicable Revolving Loan of such Borrower(s) (which application shall not result in a permanent reduction of the Revolving Loan Commitment) and upon such application, such Agent shall establish a Reserve against the Borrowing Base in an amount equal to the amount of such proceeds so applied. All insurance proceeds made available to any Credit Party that is not a Borrower to replace, repair, restore or rebuild Collateral shall be deposited in a cash collateral account. Thereafter, such funds shall be made available to such Credit Party to provide funds to replace, repair, restore or rebuild the Collateral as follows: (i) Borrower Representative shall request a Revolving Credit Advance or release from the cash collateral account be made to such Borrower or such other Credit Party, as the case may be, in the amount requested to be released; (ii) so long as the conditions set forth in Section 2.2 have been met, the applicable Lenders shall make such Revolving Credit Advance or the Applicable Agent shall release funds from the cash collateral account; and (iii) in the case of insurance proceeds applied against the Revolving Loan, the Reserve established with respect to such insurance proceeds shall be reduced by the amount of such Revolving Credit Advance. To the extent not used to replace, repair, restore or rebuild the Collateral, such insurance proceeds shall be applied in accordance with Section 1.3(d); provided that in the case of insurance proceeds pertaining to any Credit Party other than a Borrower, such insurance proceeds shall be applied ratably to all of the US Loans, in the case of a US Credit Party, and to all of the Canadian Loans, in the case of a Canadian Credit Party. Notwithstanding the provisions of this Section 5.4(c), the insurance policies covering the real estate owned by SPEs pursuant to a Permitted Sale-Leaseback and the proceeds of any such insurance policy covering such real estate may be pledged as collateral to a Mortgage Lender. A Mortgage Lender may have a first priority Lien on such insurance policies and the proceeds thereof covering such real property and may be named as loss payee and additional insured with respect to such insurance policies, limited solely to such real estate and the proceeds of damage or casualty thereto.

     5.5 Compliance with Laws.

     Each Credit Party shall comply with all federal, state, local, Canadian, provincial and foreign laws and regulations applicable to it, including those relating to ERISA and labor matters and Environmental Laws and Environmental Permits, except to the extent that the failure to comply, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

     5.6 Supplemental Disclosure.

     From time to time as may be reasonably requested by either Agent (which request will not be made more frequently than once each year absent the occurrence and continuance of a Default or an Event of Default), the Credit Parties shall supplement each Disclosure Schedule hereto, or any representation herein or in any other Loan Document, with respect to any matter hereafter arising that, if existing or occurring at the date of this Agreement, would have been required to be set forth or described in such Disclosure Schedule or as an exception to such

representation or that is necessary to correct any information in such Disclosure Schedule or representation which has been rendered inaccurate thereby (and, in the case of any supplements to any Disclosure Schedule, such Disclosure Schedule shall be appropriately marked to show the changes made therein); provided that (a) no such supplement to any such Disclosure Schedule or representation shall amend, supplement or otherwise modify any Disclosure Schedule or representation, or be or be deemed a waiver of any Default or Event of Default resulting from the matters disclosed therein, except as consented to by Agent and Requisite Lenders in writing, and (b) no supplement shall be required or permitted as to representations and warranties that relate solely to the Closing Date.

     5.7 Intellectual Property.

     Each Credit Party will conduct its business and affairs without infringement of or interference with any Intellectual Property of any other Person in any material respect.

     5.8 Environmental Matters.

     Each Credit Party shall and shall cause each Person within its control to: (a) conduct its operations and keep and maintain its Real Estate in compliance with all Environmental Laws and Environmental Permits other than noncompliance that could not reasonably be expected to have a Material Adverse Effect; (b) implement any and all investigation, remediation, removal and response actions that are appropriate or necessary to maintain the value and marketability of the Real Estate or to otherwise comply with Environmental Laws and Environmental Permits pertaining to the presence, generation, treatment, storage, use, disposal, transportation or Release of any Hazardous Material on, at, in, under, above, to, from or about any of its Real Estate; (c) notify each Agent promptly after such Credit Party becomes aware of any violation of Environmental Laws or Environmental Permits or any Release on, at, in, under, above, to, from or about any Real Estate that is reasonably likely to result in Environmental Liabilities in excess of $250,000; and (d) promptly forward to each Agent a copy of any order, notice, request for information or any communication or report received by such Credit Party in connection with any such violation or Release or any other matter relating to any Environmental Laws or Environmental Permits that could reasonably be expected to result in Environmental Liabilities in excess of $250,000, in each case whether or not the Environmental Protection Agency or any Governmental Authority has taken or threatened any action in connection with any such violation, Release or other matter. If either Agent at any time has a reasonable basis to believe that there may be a violation of any Environmental Laws or Environmental Permits by any Credit Party or any Environmental Liability arising thereunder, or a Release of Hazardous Materials on, at, in, under, above, to, from or about any of its Real Estate, that, in each case, could reasonably be expected to have a Material Adverse Effect, then each Credit Party shall, upon such Agent’s written request, (i) cause the performance of such environmental audits including subsurface sampling of soil and groundwater, and preparation of such environmental reports, at US Borrowers’ or Canadian Borrowers’, as applicable, expense, as such Agent may from time to time reasonably request, which shall be conducted by reputable environmental consulting firms reasonably acceptable to such Agent and shall be in form and substance reasonably acceptable to such Agent, and (ii) permit such Agent or its representatives to have access to all Real Estate for the purpose of conducting such environmental audits and

testing as such Agent deems appropriate, including subsurface sampling of soil and groundwater. The applicable Borrowers shall reimburse the Applicable Agent for the costs of such audits and tests and the same will constitute a part of the Obligations secured hereunder.

     5.9 Landlords’ Agreements, Mortgagee Agreements, Bailee Letters and Real Estate Purchases.

     Each Credit Party shall use all commercially reasonable efforts to obtain a landlord’s agreement, mortgagee agreement or bailee letter, as applicable, from the lessor of each leased property, mortgagee of owned property or bailee with respect to any warehouse, processor or converter facility or other location where Collateral is stored or located as of the Closing Date and as may be stored or located thereafter, which agreement or letter shall contain a waiver or subordination of all Liens or claims that the landlord, mortgagee or bailee may assert against the Collateral at that location, and shall otherwise be reasonably satisfactory in form and substance to Agent. With respect to such locations or warehouse space leased or owned following the June 2005 Closing Date (specifically excluding such locations or warehouse space leased or owned as of the June 2005 Closing Date), if Agent has not received a landlord or mortgagee agreement or bailee letter as of the date such location is acquired or leased, any Borrower’s Eligible Inventory at that location shall, in Agent’s discretion, be subject to such Reserves as may be established by Agent in its reasonable credit judgment. Each Credit Party shall use all commercially reasonable efforts to obtain a collateral access agreement from each customer which has any Collateral of any Credit Party located at its facilities (whether such facilities are owned or leased by such customer), which agreement shall contain a waiver or subordination of all Liens or claims that such customer may assert against the Collateral, provide for a release of all Liens by any other party, if any, provide for a consent and acknowledgment to the ownership and Lien of Borrowers and Lien of the Applicable Agent, in its favor and on behalf of the other Agent and Lenders, in the Collateral, provide for the segregation of all Collateral from any personal property or other assets of such customer, provide for all such UCC filings deemed necessary or desirable by the Applicable Agent and shall otherwise be satisfactory in form and substance to such Agent. After the June 2005 Closing Date, no real property or warehouse space shall be leased by any Credit Party and no Inventory shall be shipped to a processor or converter under arrangements established after the June 2005 Closing Date unless and until a satisfactory landlord agreement or bailee letter, as appropriate, shall first have been obtained with respect to such location or the Applicable Agent, in its reasonable credit judgment, shall have established an appropriate Reserve, if any. If the Applicable Agent has not received a collateral access agreement with respect to any customer location, any Borrower’s Inventory at such customer location shall not be Eligible Inventory and shall not be eligible for inclusion in any calculation of the Borrowing Base or Borrowing Availability. Each Credit Party shall timely and fully pay and perform its rent and other obligations under all leases and other agreements with respect to each leased location or public warehouse where any Collateral is or may be located. Agent reserves the right, in its discretion, to establish Reserves acceptable to Agent, in its reasonable credit judgment with respect to any leased property, any warehouse, processor or converter facility, or any other location where Collateral is stored or located as of the June 2005 Closing Date or as may be acquired or leased thereafter. In no event shall any Inventory stored or otherwise located at any customer location be considered Eligible Inventory or be otherwise eligible for inclusion in any calculation of the Borrowing Base or Borrowing Availability unless Agent shall have received a

collateral access agreement acceptable to it and any and all other actions deemed necessary or desirable by Agent (e.g. UCC filings) shall have been taken.

     5.10 Covenants Regarding Accounts.

     In the ordinary course of its business, each Credit Party processes its Accounts in a manner such that (i) each payment received by such Credit Party in respect of an Account is allocated to a specifically identified invoice, which invoice corresponds to a particular Account owing to such Credit Party and (ii) in the event that, at any time, less than 100% of the Accounts of such Credit Party are included in a Permitted Receivables Financing, payments received in respect of those Accounts included in a Permitted Receivables Financing would be identifiable and separable from payments received in respect of Accounts not so included in a Permitted Receivables Financing. WESCO DC LP shall not at any time enter into a Permitted Receivables Financing or any other similar financing or transaction.

     (b) For each Canadian Pension Plan hereafter adopted by any Credit Party which is required to be registered under the ITA or any other applicable laws, that Credit Party shall use all commercially reasonable efforts to seek and receive confirmation in writing from the applicable Governmental Authorities to the effect that such plan is unconditionally registered under the ITA and such other applicable laws.

     (c) For each existing and hereafter adopted Canadian Pension Plan and Canadian Benefit Plan, each Credit Party shall in a timely fashion perform in all material respects all obligations (including fiduciary, funding, investment and administration obligations) required to be performed in connection with such plan and the funding media therefor.

     (d) Each Credit Party shall deliver to either Agent if requested by such Agent, promptly after the filing thereof by any Credit Party with any applicable Governmental Authority, (i) copies of each annual and other return, report or valuation with respect to each Canadian Pension Plan; (ii) promptly after receipt thereof, a copy of any direction, order, notice, ruling or opinion that any Credit Party may receive from any applicable Governmental Authority with respect to any Canadian Pension Plan; and (iii) notification within 30 days of any increases having a cost to such Credit Party in excess of Canadian $250,000, or the Dollar Equivalent Amount thereof, per annum, in the benefits of any existing Canadian Pension Plan or Canadian Benefit Plan, or the establishment of any new Canadian Pension Plan or Canadian Benefit Plan, or the commencement of contributions to any such plan to which any Credit Party was not previously contributing.

     5.12 Foreign Subsidiaries’ Guaranties.

     Following a change in the relevant sections of the IRC or the regulations issued or promulgated thereunder or Canadian law, the Credit Parties shall, within fifteen (15) days of a written request by the Agent, retain an independent tax counsel reasonably satisfactory to the Agent, which counsel shall, within fifteen (15) days of its retention, deliver a written opinion addressed to the Credit Parties as to whether the entering into by any of the foreign Subsidiaries of the Borrowers organized under the laws of Canada or Mexico (a “Foreign Subsidiary”) of a guaranty in substantially the form of the Guaranties, could reasonably be expected to cause at the time such change in law becomes effective (a) any undistributed earnings of any such Foreign Subsidiary as determined for federal income tax purposes to be treated as a deemed dividend to Holdings or any Borrower for federal income tax purposes or (b) a Material Adverse Effect (either of the events specified in the foregoing clause (a) or (b) being referred to herein as a “Negative Effect”), and if such counsel does not deliver within such fifteen-day period an opinion that a Negative Effect would not occur in such circumstances, then, each such Foreign Subsidiary shall execute and deliver to the Agent (i) a guaranty in the form of the Guaranties, guaranteeing the obligations of the Credit Parties under the Loan Documents; (ii) a security agreement in the form of the Security Agreement granting to Agent or Canadian Agent, as appropriate, a Lien on all of its assets; and (iii) a pledge agreement in the form of the Pledge Agreements pledging all of the Capital Stock owned by such Credit Party to Agent or Canadian Agent, as appropriate (or the remaining portion of such Stock not previously pledged to Agent or Canadian Agent, as appropriate), it being understood that no such guaranty, security agreement or pledge agreement shall be required if such counsel delivers within such fifteen-day period an opinion that a Negative Effect would occur as a result thereof.

     5.13 Further Assurances.

     Each Credit Party executing this Agreement agrees that it shall and shall cause each other Credit Party to, at such Credit Party’s expense and upon request of each Agent, duly execute and deliver, or cause to be duly executed and delivered, to such Agent such further instruments and do and cause to be done such further acts as may be necessary or proper in the reasonable opinion of such Agent to carry out more effectively the provisions and purposes of this Agreement or any other Loan Document.

9. ASSIGNMENT AND PARTICIPATIONS; APPOINTMENT OF AGENTS

          9.1 Assignment and Participations.

           (a) Subject to the terms of this Section 9.1, any Lender may make an assignment to a Qualified Assignee of, or sale of participations in, at any time or times, the Loan Documents, Loans, Letter of Credit Obligations and any Commitment or any portion thereof or interest therein, including any Lender’s rights, title, interests, remedies, powers or duties thereunder. Any assignment by a Lender shall: (i) require the consent of Agent, which consent shall not be unreasonably withheld or delayed with respect to a Qualified Assignee, and, so long as no Default or Event of Default has occurred and is continuing, the Borrower Representative, which consent shall not be unreasonably withheld or delayed with respect to a Qualified Assignee; provided, however, that no such consent shall be required with respect to a Qualified Assignee that is a wholly-owned Affiliate of such Lender, so long as at the time of transfer to such Affiliate and upon such Affiliate becoming a Lender, it shall not be entitled to any payment from any Borrower and any other Credit Party under Sections 1.15 or 1.16; and the execution of an assignment agreement (an “Assignment Agreement” substantially in the form attached hereto as Exhibit 9.1(a) and otherwise in form and substance reasonably satisfactory to, and acknowledged by, Agent; (ii) be conditioned on such assignee Lender representing to the assigning Lender and Agent that it is purchasing the applicable Loans to be assigned to it for its own account, for investment purposes and not with a view to the distribution thereof; (iii) after giving effect to any such partial assignment, the assignee Lender shall have Commitments in an amount at least equal to $5,000,000 and the assigning Lender shall have retained Commitments in an amount at least equal to $5,000,000; and (iv) include a payment to Agent of an assignment fee of $3,500. In the case of an assignment by a Lender under this Section 9.1, the assignee shall have, to the extent of such assignment, the same rights, benefits and obligations as all other Lenders hereunder. The assigning Lender shall be relieved of its obligations hereunder with respect to its Commitments or assigned portion thereof from and after the date of such assignment. Each Borrower hereby acknowledges and agrees that any assignment shall give rise to a direct obligation of each Borrower to the assignee and that the assignee shall be considered to be a “Lender”. In all instances, each Lender’s liability to make Loans hereunder shall be several and not joint and shall be limited to such Lender’s Pro Rata Share of the applicable Commitment. In the event any Agent or any Lender assigns or otherwise transfers all or any part of the Obligations, any such Agent or any such Lender shall so notify Borrower Representative and Borrowers shall, upon the request of Agent or such Lender, execute new Notes in exchange for the Notes, if any, being assigned. Notwithstanding the foregoing provisions of this Section 9.1(a), any Lender may at any time pledge the Obligations held by it and such Lender’s rights under this Agreement and the other Loan Documents to a Federal Reserve Bank, and any lender that is an investment fund may assign the Obligations held by it and such Lender’s rights under this Agreement and the other Loan Documents to another investment fund managed by the same investment advisor; provided, that no such pledge to a Federal Reserve Bank shall release such Lender from such Lender’s obligations hereunder or under any other Loan Document. Any foreign Person that seeks to become a Lender under this Agreement shall provide a Certificate of

Exemption to Borrower Representative and Agent prior to becoming a Lender hereunder. No foreign Person may become a Lender hereunder if such Person fails to deliver a Certificate of Exemption in advance of becoming a Lender.

           (b) Any participation by a Lender of all or any part of its Commitments shall be made with the understanding that all amounts payable by Borrowers hereunder shall be determined as if that Lender had not sold such participation, and that the holder of any such participation shall not be entitled to require such Lender to take or omit to take any action hereunder except actions directly affecting (i) any reduction in the principal amount of, or interest rate or Fees payable with respect to, any Loan in which such holder participates, (ii) any extension of the scheduled amortization of the principal amount of any Loan in which such holder participates or the final maturity date thereof, and (iii) any release of all or substantially all of the Collateral (other than in accordance with the terms of this Agreement, the Collateral Documents or the other Loan Documents). Solely for purposes of Sections 1.13, 1.15, 1.16 and 9.8, each Borrower acknowledges and agrees that a participation shall give rise to a direct obligation of each Borrower to the participant and the participant shall be considered to be a “Lender”. Except as set forth in the preceding sentence neither any Borrower nor any other Credit Party shall have any obligation or duty to any participant. Neither Agent nor any Lender (other than the Lender selling a participation) shall have any duty to any participant and may continue to deal solely with the Lender selling a participation as if no such sale had occurred.

           (c) Except as expressly provided in this Section 9.1, no Lender shall, as between each Borrower and that Lender, or each Agent and that Lender, be relieved of any of its obligations hereunder as a result of any sale, assignment, transfer or negotiation of, or granting of participation in, all or any part of the Loans, the Notes or other Obligations owed to such Lender.

           (d) Each Credit Party executing this Agreement shall assist any Lender permitted to sell assignments or participations under this Section 9.1 as reasonably required to enable the assigning or selling Lender to effect any such assignment or participation, including the execution and delivery of any and all agreements, notes and other documents and instruments as shall be requested and the preparation of informational materials for, and the participation of management in meetings with, potential assignees or participants. Each Credit Party executing this Agreement shall certify the correctness, completeness and accuracy of all descriptions of the Credit Parties and their respective affairs contained in any selling materials provided by it and all other information provided by it and included in such materials, except that any Projections delivered by Borrowers shall only be certified by Borrowers as having been prepared by Borrowers in compliance with the representations contained in Section 3.4(c).

           (e) A Lender may furnish any information concerning Credit Parties in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants); provided that such Lender shall obtain from assignees or participants confidentiality covenants substantially equivalent to those contained in Section 11.8.

           (f) So long as no Event of Default has occurred and is continuing, no Lender shall assign or sell participations in any portion of its Loans or Commitments to a potential Lender or participant, if, as of the date of the proposed assignment or sale, the assignee Lender or

participant would be subject to capital adequacy or similar requirements under Section 1.16(a), increased costs under Section 1.16(b), an inability to fund LIBOR Loans under Section 1.16(c), or withholding taxes in accordance with Section 1.15(a).

          (g)  Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”), may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing by the Granting Lender to Agent and Borrower Representative, the option to provide to Borrowers all or any part of any Loans that such Granting Lender would otherwise be obligated to make to Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan; and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if such Loan were made by such Granting Lender. No SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). Any SPC may (i) with notice to, but without the prior written consent of, Borrower Representative and Agent and after paying any processing fee therefor assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by Borrower Representative and Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section 9.1(g) may not be amended without the prior written consent of each Granting Lender, all or any of whose Loans are being funded by an SPC at the time of such amendment. For the avoidance of doubt, the Granting Lender shall for all purposes, including without limitation, the approval of any amendment or waiver of any provision of any Loan Document or the obligation to pay any amount otherwise payable by the Granting Lender under the Loan Documents, continue to be the Lender of record hereunder.

Neither of the Agents shall have any duties or responsibilities except for those expressly set forth in this Agreement and the other Loan Documents. The duties of each of the Agents shall be mechanical

and administrative in nature and neither of the Agents shall have, or be deemed to have, by reason of this Agreement, any other Loan Document or otherwise a fiduciary relationship in respect of any Lender. Except as expressly set forth in this Agreement and the other Loan Documents, neither of the Agents shall have any duty to disclose, and shall not be liable for failure to disclose, any information relating to any Credit Party or any of their respective Subsidiaries or any Account Debtor that is communicated to or obtained by GE Capital, GE Capital Canada or any of their respective Affiliates in any capacity. Neither of the Agents nor any of their respective Affiliates nor any of their respective officers, directors, employees, agents or representatives shall be liable to any Lender for any action taken or omitted to be taken by them hereunder or under any other Loan Document, or in connection herewith or therewith, except for damages caused by their own gross negligence or willful misconduct.

           The execution by the Canadian Agent as the holder of an irrevocable power of attorney (fondé de pouvoir), prior to the Credit Agreement, of any deeds of hypothec or other security documents is hereby ratified and confirmed.

           If Agent or Canadian Agent shall request instructions from Requisite Lenders, Supermajority Lenders or all affected Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any other Loan Document, then Agent or Canadian Agent shall be entitled to refrain from such act or taking such action unless and until Agent or Canadian Agent shall have received instructions from Requisite Lenders, Requisite Lenders, Supermajority Lenders, or all affected Lenders, as the case may be, and neither Agent nor Canadian Agent shall incur liability to any Person by reason of so refraining. Either of the Agents shall be fully justified in failing or refusing to take any action hereunder or under any other Loan Document (a) if such action would, in the opinion of such Agent, be contrary to law or the terms of this Agreement or any other Loan Document, (b) if such action would, in the opinion of such Agent, expose such Agent to Environmental Liabilities or (c) if such Agent shall not first be indemnified to its satisfaction against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Without limiting the foregoing, no Lender shall have any right of action whatsoever against either Agent as a result of either Agent acting or refraining from acting hereunder or under any other Loan Document in accordance with the instructions of Requisite Lenders, Supermajority Lenders or all affected Lenders, as applicable.

           With effect immediately prior to any other provision of this Agreement becoming effective and prior to the effectiveness of any amendment to or restatement of any Loan Documents which amendment and restatement is dated as of the date hereof, Agent hereby irrevocably (i) assigns to and in favour of Canadian Agent, all of Agent’s right, title, interest and benefit (except as “fondé de pouvoir”, which is dealt with the following paragraphs) in and to the Existing Credit Agreement and the Loan Documents (as that term is defined in the Existing Credit Agreement, the “Existing Loan Documents”), including the benefit of any Liens created thereunder, in so far as they relate to the Canadian Borrowers, WESCO Canada and WESCO DC GP, and (ii) appoints, with respect to the Existing Loan Documents (but only in so far as they relate to the Canadian Borrowers, WESCO Canada and WESCO DC GP), Canadian Agent as agent in its place and stead (other than as “fondé de pouvoir”, which is dealt with in the following paragraphs).

           Canadian Agent hereby irrevocably accepts such assignment and appointment with respect to the Existing Loan Documents (but only in so far as they relate to the Canadian Borrowers, WESCO Canada and WESCO DC GP).

           In consideration of the assignment hereinabove mentioned and with effect as of the same time and date as such assignment, the Agent hereby resigns as the person holding an irrevocable power of attorney (fondé de pouvoir) pursuant to article 2692 of the Civil Code of Québec under the terms of the Existing Loan Documents. As and from such resignation of the Agent, for the purposes of holding any security granted by any Credit Party pursuant to the laws of the Province of Quebec, including any deed of hypothec, debenture, bond or other title of indebtedness and debenture or bond pledge agreements, Canadian Agent is hereby appointed to act as the Person holding the power of attorney (fondé de pouvoir) pursuant to article 2692 of the Civil Code of Québec to act on behalf of each present and future Canadian Lender. Each party hereto agrees that, notwithstanding Section 32 of an Act respecting the Special Powers of Legal Persons (Quebec), Canadian Agent may, as the Person holding the power of attorney of the Canadian Lenders, acquire and/or be the pledgee of any debentures, bonds or other titles of indebtedness secured by any hypothec granted by any Credit Party to the Canadian Agent, as the person holding an irrevocable power of attorney (fondé de pouvoir) pursuant to article 2692 of the Civil Code of Québec, pursuant to the laws of the Province of Quebec.

Each Credit Party covenants to promptly file, or cause to be filed, no later than 30 days after the Closing Date, any and all PPSA financing change statements or other similar registrations or documents as Canadian Agent may deem necessary or desirable to record or otherwise provide notice of the foregoing assignment, resignation and appointment.

GE Capital, as a US Lender, and GE Capital Canada, as a Canadian Lender, and their Affiliates may accept fees and other consideration from any Credit Party for services in connection with this Agreement or otherwise without having to account for the same to Lenders. Each Lender acknowledges the potential conflict of interest between GE Capital as a US Lender and GE Capital Canada as a Canadian Lender holding disproportionate interests in the US Loans and Canadian Loans, respectively, and GE Capital as Agent and GE Capital Canada as Canadian Agent.

          9.5 Lender Credit Decision.

          Each Lender acknowledges that it has, independently and without reliance upon either Agent or any other Lender and based on the Financial Statements referred to in Section 3.4(a) and such other documents and information as it has deemed appropriate, made its own credit and financial analysis of the Credit Parties and its own decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon Agent or any other Lender and based on such documents and information as it shall deem

appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement. Each Lender acknowledges the potential conflict of interest of each other Lender as a result of Lenders holding disproportionate interests in the Loans, and expressly consents to, and waives any claim based upon, such conflict of interest.

          9.6 Indemnification.

          Lenders agree to indemnify each of the Agents (to the extent not reimbursed by Credit Parties and without limiting the obligations of Borrowers hereunder), ratably according to their respective Pro Rata Shares, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against each of the Agents in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted to be taken by such Agent in connection therewith; 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 either of the Agents’ gross negligence or willful misconduct. Without limiting the foregoing, each Lender agrees to reimburse each of the Agents promptly upon demand for its ratable share of any out-of-pocket expenses (including reasonable counsel fees) incurred by such Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and each other Loan Document, to the extent that such Agent is not reimbursed for such expenses by Credit Parties.

          9.7 Successor Agent.

           (a) Agent may resign at any time by giving not less than 30 days’ prior written notice thereof to Lenders and Borrower Representative. Upon any such resignation, the Requisite Lenders shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Requisite Lenders and shall have accepted such appointment within 30 days after the resigning Agent’s giving notice of resignation, then the resigning Agent may, on behalf of Lenders, appoint a successor Agent, which shall be a US Lender, if a US Lender is willing to accept such appointment, or otherwise shall be a commercial bank or financial institution or a subsidiary of a commercial bank or financial institution if such commercial bank or financial institution is organized under the laws of the United States of America or of any State thereof and has a combined capital and surplus of at least $300,000,000. If no successor Agent has been appointed pursuant to the foregoing, within 30 days after the date such notice of resignation was given by the resigning Agent, such resignation shall become effective and the Requisite Lenders shall thereafter perform all the duties of Agent hereunder until such time, if any, as the Requisite Lenders appoint a successor Agent as provided above. Any successor Agent appointed by Requisite Lenders hereunder shall be subject to the approval of Borrower Representative, such approval not to be unreasonably withheld or delayed; provided that such approval shall not be required if a Default or an Event of Default has occurred and is continuing. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the resigning Agent. Upon the earlier of the acceptance of any appointment as

Agent hereunder by a successor Agent or the effective date of the resigning Agent’s resignation, the resigning Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents, except that any indemnity rights or other rights in favor of such resigning Agent shall continue. After any resigning Agent’s resignation hereunder, the provisions of this Section 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was acting as Agent under this Agreement and the other Loan Documents.

           (b) Canadian Agent may resign at any time by giving not less than 30 days’ prior written notice thereof to Lenders and Borrower Representative. Upon any such resignation, the Requisite Lenders shall have the right to appoint a successor Canadian Agent so long as any successor is a person which by the terms hereof would be permitted to be a Canadian Lender hereunder. If no successor Canadian Agent shall have been so appointed by the Requisite Lenders and shall have accepted such appointment within 30 days after the Canadian Agent’s giving notice of resignation, then the Canadian Agent may appoint a successor Canadian Agent, which shall be a Canadian Lender, if a Canadian Lender is willing to accept such appointment, or otherwise shall be a commercial bank or financial institution or a subsidiary of a commercial bank or financial institution if such commercial bank or financial institution is organized under the laws of Canada or of any province or territory thereof, and has a combined capital and surplus of at least $300,000,000. If no successor Canadian Agent has been appointed pursuant to the foregoing, within 30 days after the date such notice of resignation was given by the Canadian Agent, such resignation shall become effective and the Requisite Lenders shall thereafter perform all the duties of Canadian Agent hereunder until such time, if any, as the Requisite Lenders appoint a successor Canadian Agent as provided above. Any successor Canadian Agent appointed by Requisite Lenders hereunder shall be subject to the approval of Borrower Representative, such approval not to be unreasonably withheld or delayed; provided that such approval shall not be required if a Default or an Event of Default has occurred and is continuing. Upon the acceptance of any appointment as Canadian Agent hereunder by a successor Canadian Agent, such successor Canadian Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the resigning Canadian Agent. Upon the earlier of the acceptance of any appointment as Canadian Agent hereunder by a successor Canadian Agent or the effective date of the resigning Canadian Agent’s resignation, the resigning Canadian Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents, except that any indemnity rights or other rights in favor of such resigning Canadian Agent shall continue. After any resigning Canadian Agent’s resignation hereunder, the provisions of this Section 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was acting as Canadian Agent under this Agreement and the other Loan Documents.

          9.8 Setoff and Sharing of Payments.

          In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence and during the continuance of any Event of Default and subject to Section 9.9(f) and Section 12 hereof, each Lender is hereby authorized at any time or from time to time, without notice to any Credit Party or to any other Person, any such notice being hereby expressly waived, to offset and to appropriate and to apply any and all balances held by it at any of its offices for the account of any Borrower or any Guarantor (regardless of whether such balances are then due to such Borrower or any Guarantor)

and any other properties or assets at any time held or owing by that Lender or that holder to or for the credit or for the account of such Borrower or any Guarantor against and on account of any of the Obligations that are not paid when due. Any Lender exercising a right of setoff or otherwise receiving any payment on account of the Obligations in excess of its Pro Rata Share thereof shall purchase for cash (and the other Lenders or holders shall sell) such participations in each such other Lender’s or holder’s Pro Rata Share of the Obligations as would be necessary to cause such Lender to share the amount so offset or otherwise received with each other Lender or holder in accordance with their respective Pro Rata Shares, (other than offset rights exercised by any Lender with respect to Sections 1.13, 1.15 or 1.16). Each Lender’s obligation under this Section 9.8 shall be in addition to and not in limitation of its obligations to purchase a participation in an amount equal to its Pro Rata Share of the Swing Line Loans under Section 1.1. Each Borrower and each Guarantor agrees, to the fullest extent permitted by law, that (a) any Lender may exercise its right to offset with respect to amounts in excess of its Pro Rata Share of the Obligations and may sell participations in such amounts so offset to other Lenders and holders and (b) any Lender so purchasing a participation in the Loans made or other Obligations held by other Lenders or holders may exercise all rights of offset, bankers’ lien, counterclaim or similar rights with respect to such participation as fully as if such Lender or holder were a direct holder of the Loans and the other Obligations in the amount of such participation. Notwithstanding the foregoing, if all or any portion of the offset amount or payment otherwise received is thereafter recovered from the Lender that has exercised the right of offset, the purchase of participations by that Lender shall be rescinded and the purchase price restored without interest.

          9.9 Advances; Payments; Non-Funding Lenders; Information; Actions in Concert.

          (a) Advances; Payments.

                (i) Lenders shall refund or participate in the Swing Line Loan in accordance with clauses (iii) and (iv) of Section 1.1(b). If the applicable Swing Line Lender declines to make a Swing Line Loan or if Swing Line Availability is zero, the Applicable Agent shall notify Lenders, promptly after receipt of a Notice of Revolving Advance and in any event prior to 1:00 p.m. (New York time) on the date such Notice of Revolving Advance is received, by telecopy, telephone or other similar form of transmission. Each Lender shall make the amount of such Lender’s Pro Rata Share of such Revolving Credit Advance available to the Applicable Agent in same day funds by wire transfer to the Applicable Agent’s account as set forth in Annex H not later than 3:00 p.m. (New York time) on the requested funding date, in the case of an Index Rate Loan and not later than 11:00 a.m. (New York time) on the requested funding date in the case of a LIBOR Loan. After receipt of such wire transfers (or, in the Applicable Agent’s sole discretion, before receipt of such wire transfers), subject to the terms hereof, the Applicable Agent shall make the requested Revolving Credit Advance to the Borrower designated by Borrower Representative in the Notice of Revolving Credit Advance. All payments by each Lender shall be made without setoff, counterclaim or deduction of any kind.

                (ii) On the 2nd Business Day of each calendar two-week period or more frequently at the Applicable Agent’s election (each, a “Settlement Date”), such Agent shall advise each Lender by telephone, or telecopy of the amount of such Lender’s Pro Rata Share of

principal,interest and Fees paid for the benefit of Lenders with respect to each applicable Loan. Provided that each Lender has funded all payments and Advances required to be made by it and purchased all participations required to be purchased by it under this Agreement and the other Loan Documents as of such Settlement Date, each Applicable Agent shall pay to each Lender such Lender’s Pro Rata Share of principal, interest and Fees paid by Borrowers since the previous Settlement Date for the benefit of such Lender on the Loans held by it. To the extent that any Lender (a “Non-Funding Lender”) has failed to fund all such payments and Advances or failed to fund the purchase of all such participations, each Applicable Agent shall be entitled to set off the funding short-fall against that Non-Funding Lender’s Pro Rata Share of all payments received from Borrowers. Such payments shall be made by wire transfer to such Lender’s account (as specified by such Lender in Annex H or the applicable Assignment Agreement) not later than 2:00 p.m. (New York time) on the next Business Day following each Settlement Date.

          (b) Availability of Lender‘s Pro Rata Share. Agent may assume that each Lender will make its Pro Rata Share of each Revolving Credit Advance available to Agent on each funding date. If such Pro Rata Share is not, in fact, paid to each Agent by such Lender when due, such Agent will be entitled to recover such amount on demand from such Lender without setoff, counterclaim or deduction of any kind. If any Lender fails to pay the amount of its Pro Rata Share forthwith upon such Agent’s demand, such Agent shall promptly notify Borrower Representative and Borrowers shall immediately repay such amount to such Agent. Nothing in this Section 9.9(b) or elsewhere in this Agreement or the other Loan Documents shall be deemed to require such Agent to advance funds on behalf of any Lender or to relieve any Lender from its obligation to fulfill its Commitments hereunder or to prejudice any rights that Borrowers may have against any Lender as a result of any default by such Lender hereunder. To the extent that any Agent advances funds to any Borrower on behalf of any Lender and is not reimbursed therefor on the same Business Day as such Advance is made, such Agent shall be entitled to retain for its account all interest accrued on such Advance until reimbursed by the applicable Lender.

          (c) Return of Payments.

                (i) If either Agent pays an amount to a Lender under this Agreement in the belief or expectation that a related payment has been or will be received by such Agent from Borrowers and such related payment is not received by such Agent, then such Agent will be entitled to recover such amount from such Lender on demand without setoff, counterclaim or deduction of any kind.

                (ii) If any Agent determines at any time that any amount received by any Agent under this Agreement must be returned to any Borrower or paid to any other Person pursuant to any insolvency law or otherwise, then, notwithstanding any other term or condition of this Agreement or any other Loan Document, the Applicable Agent will not be required to distribute any portion thereof to any Lender. In addition, each Lender will repay to the Applicable Agent on demand any portion of such amount that the Applicable Agent has distributed to such Lender, together with interest at such rate, if any, as the Applicable Agent is required to pay to any Borrower or such other Person, without setoff, counterclaim or deduction of any kind.

          (d) Non-Funding Lenders. The failure of any Non-Funding Lender to make any Revolving Credit Advance or any payment required by it hereunder, or to purchase any participation in any Swing Line Loan to be made or purchased by it on the date specified therefor shall not relieve any other Lender (each such other Lender, an “Other Lender”) of its obligations to make such Advance or purchase such participation on such date, but neither any Other Lender nor Agent shall be responsible for the failure of any Non-Funding Lender to make an Advance, purchase a participation or make any other payment required hereunder. Notwithstanding anything set forth herein to the contrary, a Non-Funding Lender shall not have any voting or consent rights under or with respect to any Loan Document or constitute a “Lender” or a “Lender” (or be included in the calculation of “Requisite Lenders” or “Supermajority Lenders” hereunder) for any voting or consent rights under or with respect to any Loan Document. At Borrower Representative’s request, Agent or a Person acceptable to Agent shall have the right with Agent’s consent and in Agent’s sole discretion (but shall have no obligation) to purchase from any Non-Funding Lender, and each Non-Funding Lender agrees that it shall, at Agent’s request, sell and assign to Agent or such Person, all of the Commitments of that Non-Funding Lender for an amount equal to the principal balance of all Loans held by such Non-Funding Lender and all accrued interest and fees with respect thereto through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment Agreement.

          (e) Dissemination of Information. Each Agent shall use reasonable efforts to provide Lenders with any notice of Default or Event of Default received by such Agent from, or delivered by such Agent to, any Credit Party, with notice of any Event of Default of which such Agent has actually become aware and with notice of any action taken by Agent following any Event of Default, and, regardless of whether a Default or Event of Default is in existence, copies of any collateral audits and appraisals as such Agent may have conducted; provided, that neither Agent nor Canadian Agent shall be liable to any Lender for any failure to do so, except to the extent that such failure is attributable to such Agent’s gross negligence or willful misconduct.

          (f) Actions in Concert. Anything in this Agreement to the contrary notwithstanding, each Lender hereby agrees with each other Lender that no Lender shall take any action to protect or enforce its rights arising out of this Agreement or the Notes (including exercising any rights of setoff) without first obtaining the prior written consent of Agent or Requisite Lenders, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the Notes shall be taken in concert and at the direction or with the consent of Agent or Requisite Lenders.

          9.10 Syndication Agent and Documentation Agent.

           The parties hereto acknowledge and agree that no Person shall have, by reason of its designation as Syndication Agent or Documentation Agent, any power, duty, responsibility or liability whatsoever under this Agreement or any other Loan Document.

10. SUCCESSORS AND ASSIGNS

           10.1 Successors and Assigns.

           This Agreement and the other Loan Documents shall be binding on and shall inure to the benefit of each Credit Party, each Agent, Lenders and their respective successors and assigns (including, in the case of any Credit Party, a debtor-in-possession on behalf of such Credit Party), except as otherwise provided herein or therein. No Credit Party may assign, transfer, hypothecate or otherwise convey its rights, benefits, obligations or duties hereunder or under any of the other Loan Documents without the prior express written consent of Agents and Lenders. Any such purported assignment, transfer, hypothecation or other conveyance by any Credit Party without the prior express written consent of Agents and Lenders shall be void. The terms and provisions of this Agreement are for the purpose of defining the relative rights and obligations of each Credit Party, Agents and Lenders with respect to the transactions contemplated hereby and no Person shall be a third party beneficiary of any of the terms and provisions of this Agreement or any of the other Loan Documents.

           11.2 Amendments and Waivers.

           (a) Except for actions expressly permitted to be taken by either Agent, no amendment, modification, termination or waiver of any provision of this Agreement or any other Loan Document, or any consent to any departure by any Credit Party therefrom, shall in any event be effective unless the same shall be in writing and signed by Agents and Borrowers, and by Requisite Lenders, Supermajority Lenders or all affected Lenders, as applicable. Except as set forth in clauses (b) and (c) below, all such amendments, modifications, terminations or waivers requiring the consent of any Lenders shall require the written consent of Requisite Lenders. For purposes of clarity, the parties hereto hereby acknowledge and agree that all actions that require the consent of Lenders or any subgroup of Lenders referred to in this Agreement (i.e., Requisite Lenders, Requisite Revolving Lenders or Supermajority Lenders) shall include Canadian Lenders and US Lenders, collectively, regardless of whether Loans or Borrowers or other matters affected thereby are exclusively related to one jurisdiction (i.e., U.S. or Canada) or the other.

           (b) No amendment, modification, termination or waiver of or consent with respect to any provision of this Agreement that increases the percentage advance rates set forth in

the definition of the US Borrowing Base or the Canadian Borrowing Base, or that makes less restrictive the nondiscretionary criteria for exclusion from Eligible Accounts and Eligible Inventory set forth in Sections 1.6 and 1.7, shall be effective unless the same shall be in writing and signed by each Agent, Supermajority Lenders and Borrowers.

          (c)  No amendment, modification, termination or waiver shall, unless in writing and signed by Agent and each Lender directly affected thereby: (i) increase the principal amount of any Lender’s Commitment (which action shall be deemed only to affect those Lenders whose Commitments are increased and may be approved by Requisite Lenders, including those lenders whose Commitments are increased); (ii) reduce the principal of, rate of interest on or Fees payable with respect to any Loan or Letter of Credit Obligations of any affected Lender; (iii) extend any scheduled payment date (other than payment dates of mandatory prepayments under Section 1.3(b)(ii) and (iii)) or final maturity date of the principal amount of any Loan of any affected Lender; (iv) waive, forgive, defer, extend or postpone any payment of interest or Fees as to any affected Lender; (v) release any Guaranty or, except as otherwise permitted herein or in the other Loan Documents, release, or permit any Credit Party to sell or otherwise dispose of, any Collateral with a value exceeding $20,000,000 in the aggregate during the term of this Agreement (which action shall be deemed to directly affect all Lenders); (vi) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Loans that shall be required for Lenders or any of them to take any action hereunder; and (vii) amend or waive this Section 11.2 or the definitions of the terms “Requisite Lenders” or “Supermajority Lenders” insofar as such definitions affect the substance of this Section 11.2. Furthermore, no amendment, modification, termination or waiver affecting the rights or duties of Agent or L/C Issuer under this Agreement or any other Loan Document shall be effective unless in writing and signed by Agent or L/C Issuer, as the case may be, in addition to Lenders required hereinabove to take such action. Each amendment, modification, termination or waiver shall be effective only in the specific instance and for the specific purpose for which it was given. No amendment, modification, termination or waiver shall be required for either Agent to take additional Collateral pursuant to any Loan Document. No amendment, modification, termination or waiver of any provision of any Note shall be effective without the written concurrence of the holder of that Note. No notice to or demand on any Credit Party in any case shall entitle such Credit Party or any other Credit Party to any other or further notice or demand in similar or other circumstances. Any amendment, modification, termination, waiver or consent effected in accordance with this Section 11.2 shall be binding upon each holder of the Notes at the time outstanding and each future holder of the Notes.

           (d) If, in connection with any proposed amendment, modification, waiver or termination (a “Proposed Change”):

                (i) requiring the consent of all affected Lenders, the consent of Requisite Lenders is obtained, but the consent of other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained as described in this clause (i) and in clause (ii) below being referred to as a “Non-Consenting Lender”), or

                (ii) requiring the consent of Supermajority Lenders, the consent of Requisite Lenders is obtained, but the consent of Supermajority Lenders is not obtained, then, so

long as Agent is not a Non-Consenting Lender, at Borrower Representative’s request Agent, or a Person reasonably acceptable to Agent, shall have the right with Agent’s consent and in Agent’s sole discretion (but shall have no obligation) to purchase from such Non-Consenting Lenders, and such Non-Consenting Lenders agree that they shall, upon Agent’s request, sell and assign to Agent or such Person, all of the Commitments of such Non-Consenting Lenders for an amount equal to the principal balance of all Loans held by the Non-Consenting Lenders and all accrued interest and Fees with respect thereto through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment Agreement.

           (e) Upon payment in full in cash and performance of all of the Obligations (other than indemnification Obligations), termination of the Commitments and a release of all claims against each Agent and Lenders, and so long as no suits, actions proceedings, or claims are pending or threatened against any Indemnified Person asserting any damages, losses or liabilities that are Indemnified Liabilities, the Applicable Agent shall deliver to Borrowers termination statements, mortgage releases and other documents necessary or appropriate to evidence the termination of the Liens securing payment of the Obligations.

           (a) the forwarding to Borrowers or any other Person on behalf of Borrowers by any Agent of the proceeds of any Loan;

           (b) any amendment, modification or waiver of, or consent with respect to, or termination of, any of the Loan Documents or Related Transactions Documents or advice in connection with the syndication and administration of the Loans made pursuant hereto or its rights hereunder or thereunder;

           (c) any litigation, contest, dispute, suit, proceeding or action (whether instituted by either Agent, any Lender, any Credit Party or any other Person and whether as a party, witness or otherwise) in any way relating to the Collateral, any of the Loan Documents or any other agreement to be executed or delivered in connection herewith or therewith, including any litigation, contest, dispute, suit, case, proceeding or action, and any appeal or review thereof, in connection with a case commenced by or against any Credit Party or any other Person that may be obligated to either Agent by virtue of the Loan Documents, including any such litigation, contest, dispute, suit, proceeding or action arising in connection with any work-out or restructuring of the Loans during the pendency of one or more Events of Default; provided that in the case of reimbursement of counsel for Lenders other than either Agent, such reimbursement shall be limited to one counsel for all US Lenders and one counsel for all Canadian Lenders;

provided, further, that no Person shall be entitled to reimbursement under this clause (c) in respect of any litigation, contest, dispute, suit, proceeding or action to the extent any of the foregoing results from such Person’s gross negligence or willful misconduct;

           (d) any attempt to enforce any remedies of either Agent or any Lender against any or all of the Credit Parties or any other Person that may be obligated to either Agent or any Lender by virtue of any of the Loan Documents, including any such attempt to enforce any such remedies in the course of any work-out or restructuring of the Loans during the pendency of one or more Events of Default; provided, that in the case of reimbursement of counsel for Lenders other than either Agent, such reimbursement shall be limited to one counsel for all US Lenders and one counsel for all Canadian Lenders;

           11.4 No Waiver.

           No failure by either Agent or any Lender, at any time or times, to require strict performance by the Credit Parties of any provision of this Agreement or any other Loan Document shall waive, affect or diminish any right of such Agent or such Lender thereafter to demand strict compliance and performance herewith or therewith. Any suspension or waiver of an Event of Default shall not suspend, waive or affect any other Event of Default whether the same is prior or subsequent thereto and whether the same or of a different type. Subject to the provisions of Section 11.2, none of the undertakings, agreements, warranties, covenants and representations of any Credit Party contained in this Agreement or any of the other Loan Documents and no Default or Event of Default by any Credit Party shall be deemed to have been suspended or waived by either Agent or any Lender, unless such waiver or suspension is by an

instrument in writing signed by an officer of or other authorized employee of such Agent and the applicable required Lenders and directed to Borrowers specifying such suspension or waiver.

           11.5 Remedies.

           Each Agent’s and Lenders’ rights and remedies under this Agreement shall be cumulative and nonexclusive of any other rights and remedies that such Agent or any Lender may have under any other agreement, including the other Loan Documents, by operation of law or otherwise. Recourse to the Collateral shall not be required.

           11.6 Severability.

           Wherever possible, each provision of this Agreement and the other Loan Documents shall be interpreted in such a manner as to be effective and valid under applicable law, but if any provision of this Agreement or any other Loan Document shall be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement or such other Loan Document.

           11.7 Conflict of Terms.

           Except as otherwise provided in this Agreement or any of the other Loan Documents by specific reference to the applicable provisions of this Agreement, if any provision contained in this Agreement conflicts with any provision in any of the other Loan Documents, the provision contained in this Agreement shall govern and control.

           11.8 Confidentiality.

           Each Agent and each Lender agrees to use commercially reasonable efforts (equivalent to the efforts such Agent or such Lender applies to maintain the confidentiality of its own confidential information) to maintain as confidential all confidential information provided to them by the Credit Parties and designated as confidential for a period of 2 years following receipt thereof, except that either Agent and each Lender may disclose such information (a) to Persons employed or engaged by Agent or such Lender in evaluating, approving, structuring or administering the Loans and the Commitments; (b) to any bona fide assignee or participant or potential assignee or participant that has agreed to comply with the covenant contained in this Section 11.8 (and any such bona fide assignee or participant or potential assignee or participant may disclose such information to Persons employed or engaged by them as described in clause (a) above); (c) as required or requested by any Governmental Authority or reasonably believed by either Agent or such Lender to be compelled by any court decree, subpoena or legal or administrative order or process; (d) as, on the advice of either Agent’s or such Lender’s counsel, is required by law; (e) in connection with the exercise of any right or remedy under the Loan Documents or in connection with any Litigation to which either Agent or such Lender is a party; or (f) that ceases to be confidential through no fault of either Agent or any Lender.

           11.9 GOVERNING LAW.

           EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN ANY OF THE LOAN DOCUMENTS, IN ALL RESPECTS, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE, THE LOAN DOCUMENTS AND THE OBLIGATIONS SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED IN THAT STATE AND ANY APPLICABLE LAWS OF THE UNITED STATES OF AMERICA. EACH CREDIT PARTY HEREBY CONSENTS AND AGREES THAT THE STATE OR FEDERAL COURTS LOCATED IN NEW YORK COUNTY, CITY OF NEW YORK, NEW YORK SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN THE CREDIT PARTIES, AGENTS AND LENDERS PERTAINING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR TO ANY MATTER ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS; PROVIDED, THAT AGENTS, LENDERS AND THE CREDIT PARTIES ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF NEW YORK COUNTY AND; PROVIDED, FURTHER THAT NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE EITHER AGENT FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF SUCH AGENT. EACH CREDIT PARTY EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND EACH CREDIT PARTY HEREBY WAIVES ANY OBJECTION THAT SUCH CREDIT PARTY MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS AND HEREBY CONSENTS TO THE GRANTING OF SUCH LEGAL OR EQUITABLE RELIEF AS IS DEEMED APPROPRIATE BY SUCH COURT. EACH CREDIT PARTY HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINTS AND OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO SUCH CREDIT PARTY AT THE ADDRESS SET FORTH IN ANNEX I OF THIS AGREEMENT AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE EARLIER OF SUCH CREDIT PARTY’S ACTUAL RECEIPT THEREOF OR 3 DAYS AFTER DEPOSIT IN THE UNITED STATES MAILS, PROPER POSTAGE PREPAID.

           11.10 Notices.

           Except as otherwise provided herein, whenever it is provided herein that any notice, demand, request, consent, approval, declaration or other communication shall or may be given to or served upon any of the parties by any other parties, or whenever any of the parties

desires to give or serve upon any other parties any communication with respect to this Agreement, each such notice, demand, request, consent, approval, declaration or other communication shall be in writing and shall be deemed to have been validly served, given or delivered (a) upon the earlier of actual receipt and 3 Business Days after deposit in the United States Mail, registered or certified mail, return receipt requested, with proper postage prepaid, (b) upon transmission, when sent by telecopy or other similar facsimile transmission (with such telecopy or facsimile promptly confirmed by delivery of a copy by personal delivery or United States Mail as otherwise provided in this Section 11.10); (c) 1 Business Day after deposit with a reputable overnight courier with all charges prepaid or (d) when delivered, if hand-delivered by messenger, all of which shall be addressed to the party to be notified and sent to the address or facsimile number indicated in Annex I or to such other address (or facsimile number) as may be substituted by notice given as herein provided. The giving of any notice required hereunder may be waived in writing by the party entitled to receive such notice. Failure or delay in delivering copies of any notice, demand, request, consent, approval, declaration or other communication to any Person (other than Borrower Representative or either Agent) designated in Annex I to receive copies shall in no way adversely affect the effectiveness of such notice, demand, request, consent, approval, declaration or other communication.

           11.11 Section Titles.

           The Section titles and Table of Contents contained in this Agreement are and shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreement between the parties hereto.

           11.12 Counterparts.

           This Agreement may be executed in any number of separate counterparts, each of which shall collectively and separately constitute one agreement.

           11.13 WAIVER OF JURY TRIAL.

           BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, AMONG AGENTS, LENDERS AND ANY CREDIT PARTY ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED AMONG THEM IN CONNECTION WITH, THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS RELATED THERETO.

           11.14 Press Releases and Related Matters.

           Each Credit Party executing this Agreement agrees that neither it nor its Affiliates will in the future issue any press releases or other public disclosure using the name of GE Capital, GE Capital Canada or its affiliates or referring to this Agreement, the other Loan Documents or the Related Transactions Documents without at least 2 Business Days’ prior notice to GE Capital and GE Capital Canada and without the prior written consent of GE Capital unless (and only to the extent that) such Credit Party or Affiliate is required to do so under law and then, in any event, such Credit Party or Affiliate will consult with GE Capital and GE Capital Canada before issuing such press release or other public disclosure. Each Credit Party consents to the publication by either Agent or any Lender of a tombstone or similar advertising material relating to the financing transactions contemplated by this Agreement. Each Agent or such Lender shall provide a draft of any such tombstone or similar advertising material to each Credit Party for review and comment prior to the publication thereof. Each Agent reserves the right to provide to industry trade organizations information necessary and customary for inclusion in league table measurements. Each Credit Party executing this Agreement agrees that neither it nor its Affiliates will in the future issue any press release or public disclosure (other than Securities and Exchange Commission filings required to be made by law) using the name of any Lender (other than as provided above with respect to GE Capital and GE Capital Canada) without the prior consent of such Lender.

           11.15 Reinstatement.

           This Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against (or similar proceeding be instituted by or against) any Borrower or any other Credit Party for liquidation or reorganization, should any Credit Party become insolvent or make an assignment for the benefit of any creditor or creditors or should an interim receiver, receiver, receiver and manager or trustee be appointed for all or any significant part of any Credit Party’s assets, and shall continue to be effective or to be reinstated, as the case may be, if at any time payment and performance of the Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

           11.16 Advice of Counsel.

           Each of the parties represents to each other party hereto that it has discussed this Agreement and, specifically, the provisions of Sections 11.9 and 11.13, with its counsel.

           11.17 No Strict Construction.

           The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this

Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.

           11.18 Judgment Currency.

     (a) If, for the purpose of obtaining or enforcing judgment against any Credit Party in any court in any jurisdiction, it becomes necessary to convert into any other currency (such other currency being hereinafter in this Section 11.18 referred to as the “Judgment Currency”) an amount due under any Loan Document in any currency (the “Obligation Currency”) other than the Judgment Currency, the conversion shall be made at the rate of exchange prevailing on the Business Day immediately preceding (i) the date of actual payment of the amount due, in the case of any proceeding in the courts of any jurisdiction that will give effect to such conversion being made on such date, or (ii) the date on which the judgment is given, in the case of any proceeding in the courts of any other jurisdiction (the applicable date as of which such conversion is made pursuant to this Section 11.18 being hereinafter in this Section 11.18 referred to as the “Judgment Conversion Date”).

           (b) If, in the case of any proceeding in the court of any jurisdiction referred to in Section 11.18(a), there is a change in the rate of exchange prevailing between the Judgment Conversion Date and the date of actual receipt for value of the amount due, the applicable Credit Party shall pay such additional amount (if any, but in any event not a lesser amount) as may be necessary to ensure that the amount actually received in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of the Obligation Currency which could have been purchased with the amount of the Judgment Currency stipulated in the judgment or judicial order at the rate of exchange prevailing on the Judgment Conversion Date. Any amount due from a Credit Party under Section 11.18(b) shall be due as a separate debt and shall not be affected by judgment being obtained for any other amounts due under or in respect of any of the Loan Documents.

           (c) The term “rate of exchange” in this Section 11.18 means the rate of exchange at which the Agent would, on the relevant date at or about 12:00 noon (New York time), be prepared to sell the Obligation Currency against the Judgment Currency.

           11.19 Designated Senior Indebtedness.

           Holdings and Borrower hereby specifically designate the Indebtedness evidenced by this Agreement and the other Loan Documents (specifically including all Obligations) as “Senior Indebtedness” and “Designated Senior Indebtedness” for all purposes, including, without limitation, for purposes of any indenture evidencing or otherwise governing the Notes or any other Subordinated Debt, including, without limitation, any additional Subordinated Notes or Indebtedness issued in compliance with the provisions of Sections 6.3(a) (xxii) and (xxiv).

           11.20 Amendment and Restatement.

           This Agreement amends and restates in its entirety the Existing Credit Agreement and upon the effectiveness of this Agreement, the terms and provisions of the Existing Credit Agreement shall, subject to this Section 11.20, be superseded hereby. All references to the “Credit Agreement” contained in the Loan Documents delivered in connection with the Existing Credit Agreement or this Agreement shall, and shall be deemed to, refer to this Agreement. Notwithstanding the amendment and restatement of the Existing Credit Agreement by this Agreement, the Obligations of the Borrowers and the other Credit Parties outstanding under the Existing Credit Agreement and the other Loan Documents as of the Closing Date shall remain outstanding and shall constitute continuing Obligations and shall continue as such to be secured by the Collateral. Such Obligations shall in all respects be continuing and this Agreement shall not be deemed to evidence or result in a novation or repayment and reborrowing of such Obligations. The Liens securing payment of the Obligations under the Existing Credit Agreement, as amended and restated in the form of this Agreement, shall in all respects be continuing, securing the payment of all Obligations. In addition, each Borrower and each Credit Party hereby acknowledges, confirms and agrees that all Intercompany Notes executed prior to the Closing Date in connection with the Existing Credit Agreement shall remain outstanding, and each party thereto reaffirms its obligations and liabilities under such Intercompany Notes.

           11.21 Patriot Act Notice.

           Each Lender subject to the USA Patriot Act of 2001 (31 U.S.C. 5318 et seq.) hereby notifies the Borrowers that, pursuant to Section 326 thereof, it is required to obtain, verify and record information that identifies the Borrowers, including the name and address of each Borrower and other information allowing such Lender to identify the Borrowers in accordance with such act.

12. CROSS-GUARANTY

           12.1 Cross-Guaranty.

           Each Borrower hereby agrees that such Borrower is jointly and severally liable for, and hereby absolutely and unconditionally guarantees to each Agent and Lender and their respective successors and assigns, the full and prompt payment (whether at stated maturity, by acceleration or otherwise) and performance of, all Obligations owed or hereafter owing to each Agent and Lender by each other Borrower; provided, that, notwithstanding any other provision of this Agreement, no Canadian Borrower shall be obligated to guaranty, and no Canadian Borrower shall be deemed to have guaranteed, the Obligations of any US Borrower hereunder; provided further, that, for the avoidance of doubt, the assets of any Canadian Borrower may not and shall not serve at any time, even indirectly, as security for the performance or Obligations of any US Borrower. Each Borrower agrees that its guaranty obligation hereunder is a continuing guaranty of payment and performance and not of collection, that its obligations under this Section 12 shall not be discharged until payment and performance, in full, of the Obligations has occurred, and that its obligations under this Section 12 shall be absolute and unconditional, irrespective of, and unaffected by,

           (a) the genuineness, validity, regularity, enforceability or any future amendment of, or change in, this Agreement, any other Loan Document or any other agreement, document or instrument to which any Borrower is or may become a party;

           (b) the absence of any action to enforce this Agreement (including this Section 12) or any other Loan Document or the waiver or consent by either Agent or any Lender with respect to any of the provisions thereof;

           (c) the existence, value or condition of, or failure to perfect its Lien against, any security for the Obligations or any action, or the absence of any action, by either Agent or any Lender in respect thereof (including the release of any such security);

           (d) the insolvency of any Credit Party; or

           (e) any other action or circumstances that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor.

Each Borrower shall be regarded, and shall be in the same position, as principal debtor with respect to the Obligations guaranteed hereunder.

           12.2 Waivers by Borrowers.

           Each Borrower expressly waives all rights it may have now or in the future under any statute, or at common law, or at law or in equity, or otherwise, to compel either Agent or any Lender to marshal assets or to proceed in respect of the Obligations guaranteed hereunder against any other Credit Party, any other party or against any security for the payment and performance of the Obligations before proceeding against, or as a condition to proceeding against, such Borrower. It is agreed among each Borrower, each Agent and Lenders that the foregoing waivers are of the essence of the transaction contemplated by this Agreement and the other Loan Documents and that, but for the provisions of this Section 12 and such waivers, Agents and Lenders would decline to enter into this Agreement.

           12.3 Benefit of Guaranty.

           Each Borrower agrees that the provisions of this Section 12 are for the benefit of each Agent and Lender and their respective successors, transferees, endorsees and assigns, subject to the restrictions regarding the guaranty by the Canadian Borrowers as set forth in Section 12.1 hereof, and nothing herein contained shall impair, as between any other Borrower and either Agent or any Lender, the obligations of such other Borrower under the Loan Documents.

           12.4 Waiver of Subrogation, Etc.

           Notwithstanding anything to the contrary in this Agreement or in any other Loan Document, and except as set forth in Section 12.7, each Borrower hereby expressly and irrevocably waives any and all rights at law or in equity to subrogation, reimbursement, exoneration, contribution, indemnification or set off and any and all defenses available to a

surety, guarantor or accommodation co-obligor. Each Borrower acknowledges and agrees that this waiver is intended to benefit each Agent and Lender and shall not limit or otherwise affect such Borrower’s liability hereunder or the enforceability of this Section 12, and that each Agent and Lender and their respective successors and assigns are intended third party beneficiaries of the waivers and agreements set forth in this Section 12.4.

           12.5 Election of Remedies.

           If either Agent or any Lender may, under applicable law, proceed to realize its benefits under any of the Loan Documents giving such Agent or Lender a Lien upon any Collateral, whether owned by any Borrower or by any other Person, either by judicial foreclosure or by non-judicial sale or enforcement, such Agent or Lender may, at its sole option, determine which of its remedies or rights it may pursue without affecting any of its rights and remedies under this Section 12. If, in the exercise of any of its rights and remedies, either Agent or any Lender shall forfeit any of its rights or remedies, including its right to enter a deficiency judgment against any Borrower or any other Person, whether because of any applicable laws pertaining to “election of remedies” or the like, each Borrower hereby consents to such action by such Agent or Lender and waives any claim based upon such action, even if such action by such Agent or Lender shall result in a full or partial loss of any rights of subrogation that each Borrower might otherwise have had but for such action by such Agent or Lender. Any election of remedies that results in the denial or impairment of the right of either Agent or any Lender to seek a deficiency judgment against any Borrower shall not impair any other Borrower’s obligation to pay the full amount of the Obligations. In the event either Agent or any Lender shall bid at any foreclosure or trustee’s sale or at any private sale permitted by law or the Loan Documents, such Agent or Lender may bid all or less than the amount of the Obligations and the amount of such bid need not be paid by such Agent or Lender but shall be credited against the Obligations. The amount of the successful bid at any such sale, whether either Agent, any Lender or any other party is the successful bidder, shall be conclusively deemed to be the fair market value of the Collateral and the difference between such bid amount and the remaining balance of the Obligations shall be conclusively deemed to be the amount of the Obligations guaranteed under this Section 12, notwithstanding that any present or future law or court decision or ruling may have the effect of reducing the amount of any deficiency claim to which either Agent or any Lender might otherwise be entitled but for such bidding at any such sale.

           12.6 Limitation.

           Notwithstanding any provision herein contained to the contrary, each US Borrower’s liability under this Section 12 (which liability is in any event in addition to amounts for which such Borrower is primarily liable under Section 1) shall be limited to an amount not to exceed as of any date of determination the greater of:

           (a) the net amount of all Loans advanced to any other Borrower under this Agreement and then re-loaned or otherwise transferred to, or for the benefit of, such US Borrower; and

           (b) the amount that could be claimed by Agents and Lenders from such US Borrower under this Section 12 without rendering such claim voidable or avoidable under Section 548 of Chapter 11 of the Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law after taking into account, among other things, such US Borrower’s right of contribution and indemnification from each other Borrower under Section 12.7.

           12.7 Contribution with Respect to Guaranty Obligations.

           (a) To the extent that any Borrower shall make a payment under this Section 12 of all or any of the Obligations (other than Loans made to that Borrower for which it is primarily liable) (a “Guarantor Payment”) that, taking into account all other Guarantor Payments then previously or concurrently made by any other Borrower, exceeds the amount that such Borrower would otherwise have paid if each Borrower had paid the aggregate Obligations satisfied by such Guarantor Payment in the same proportion that such Borrower’s “Allocable Amount” (as defined below) (as determined immediately prior to such Guarantor Payment) bore to the aggregate Allocable Amounts of each of the Borrowers as determined immediately prior to the making of such Guarantor Payment, then, following indefeasible payment in full in cash of the Obligations and termination of the Commitments, such Borrower shall be entitled to receive contribution and indemnification payments from, and be reimbursed by, each other Borrower for the amount of such excess, pro rata based upon their respective Allocable Amounts in effect immediately prior to such Guarantor Payment.

           (b) As of any date of determination, the “Allocable Amount” of any Borrower shall be equal to the maximum amount of the claim that could then be recovered from such Borrower under this Section 12 without rendering such claim voidable or avoidable under Section 548 of Chapter 11 of the Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law.

           (c) This Section 12.7 is intended only to define the relative rights of Borrowers and nothing set forth in this Section 12.7 is intended to or shall impair the obligations of Borrowers, jointly and severally, to pay any amounts as and when the same shall become due and payable in accordance with the terms of this Agreement, including Section 12.1 and the restrictions therein. Nothing contained in this Section 12.7 shall limit the liability of any Borrower to pay the Loans made directly or indirectly to that Borrower and accrued interest, Fees and expenses with respect thereto for which such Borrower shall be primarily liable.

           (d) The parties hereto acknowledge that the rights of contribution and indemnification hereunder shall constitute assets of the Borrower to which such contribution and indemnification is owing.

           (e) The rights of the indemnifying Borrowers against other Credit Parties under this Section 12.7 shall be exercisable upon the full and indefeasible payment of the Obligations and the termination of the Commitments.

           12.8 Liability Cumulative.

           The liability of Borrowers under this Section 12 is in addition to and shall be cumulative with all liabilities of each Borrower to either Agent or any Lender under this Agreement and the other Loan Documents to which such Borrower is a party or in respect of any Obligations or obligation of the other Borrower, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the contrary.

13. LIENS AND LOAN PRIORITIES

           13.1 Priorities.

           It is the intention of the parties hereto that the Canadian Credit Parties not guarantee or otherwise be liable for any of the US Obligations or that any of their assets constitute Collateral for any of the US Obligations. Accordingly, notwithstanding any provision of this Agreement (including any Annex hereto) or any other Loan Document to the contrary, but except as otherwise expressly provided for in this Section 13.1, no cash or assets of any Canadian Credit Party or any proceeds of any such assets shall be applied, directly or indirectly, to the US Obligations. Notwithstanding any provision of this Agreement to the contrary, the parties acknowledge and agree to the pledge of 65% of the Stock of any Canadian Credit Party owned by any US Credit Party to secure the US Obligations. Notwithstanding any provisions of this Agreement or any of the other Loan Documents to the contrary, the parties acknowledge and agree that all Collateral of the Canadian Credit Parties and the US Credit Parties shall secure the Canadian Obligations, and there shall be no requirement for the Canadian Agent or Canadian Lenders to seek recourse first or to fully enforce their or its respective remedies with respect to, Collateral or Guaranties of the Canadian Credit Parties prior to seeking or obtaining recourse with respect to the Collateral or Guaranties of the US Credit Parties.

ANNEX B (Section 1.2)
to
AMENDED AND RESTATED CREDIT AGREEMENT

LETTERS OF CREDIT

          (a) Issuance. Subject to the terms and conditions of the Agreement, (i) Agent and US Lenders agree to incur, from time to time prior to the Commitment Termination Date, upon the request of Borrower Representative on behalf of any US Borrower and for such US Borrower’s account, US Letter of Credit Obligations, (ii) Canadian Agent and Canadian Lenders agree to incur, from time to time prior to the Commitment Termination Date, upon the request of Borrower Representative on behalf of any Canadian Borrower and for such Canadian Borrower’s account, Canadian Letter of Credit Obligations by causing, in the cases of requests for US Letters of Credit, US Letters of Credit to be issued by GE Capital or a Subsidiary thereof or a bank or other legally authorized Person selected by or acceptable to Agent in its sole discretion, or, in the case of requests for Canadian Letters of Credit by causing Canadian Letters of Credit to be issued by GE Capital Canada or an Affiliate thereof or a bank or other legally authorized Person selected by or acceptable to Canadian Agent (each, an “L/C Issuer”) for US Borrower’s account, in the case of US Letters of Credit, and Canadian Borrower’s account, in the case of Canadian Letters of Credit; provided, that if the L/C Issuer is a Canadian Lender, in the case of a Canadian Letter of Credit, then such Letters of Credit shall not be guaranteed by the Canadian Agent but rather each Canadian Lender shall, subject to the terms and conditions hereinafter set forth, purchase (or be deemed to have purchased) risk participations in all such Letters of Credit issued with the written consent of the Canadian Agent under the applicable Facilities, as more fully described in paragraph (b)(ii) below. The aggregate amount of all Letter of Credit Obligations shall not at any time exceed the least of (i) Forty-Five Million Dollars ($45,000,000) (the “US L/C Sublimit”), (ii) the Maximum US Amount less the aggregate outstanding principal balance of the US Revolving Credit Advances and US Swing Line Loans, and (iii) the US Borrowing Base less the aggregate outstanding principal balance of the US Revolving Credit Advances and US Swing Line Loans. The aggregate amount of all Canadian Letter of Credit Obligations shall not at any time exceed the least of (i) $5,000,000 Million Dollars or the Canadian Dollar Equivalent Amount thereof (the “Canadian L/C Sublimit”), (ii) the Maximum Canadian Amount less the aggregate outstanding principal balance of the Canadian Revolving Credit Advances and Canadian Swing Line Loans, and (iii) the Canadian Borrowing Base less the aggregate outstanding principal balance of the Canadian Revolving Credit Advances and Canadian Swing Line Loans. No such Letter of Credit shall have an expiry date that is more than one year following the date of issuance thereof, unless otherwise determined by the Agent, in its sole discretion, and neither of the Agents nor any Lender shall be under any obligation to incur Letter of Credit Obligations in respect of, or purchase risk participations in, any Letter of Credit having an expiry date that is later than the Commitment Termination Date.

          (b) (i) Advances Automatic; Participations. In the event that Agent or a US Lender shall make any payment on or pursuant to any US Letter of Credit Obligation, such payment shall then be deemed automatically to constitute a US Revolving Credit Advance to the US Borrower, for whose account such US Letter of Credit Obligation was incurred, under

Section 1.1(a) of the Agreement regardless of whether a Default or Event of Default has occurred and is continuing and notwithstanding US Borrowers’ failure to satisfy the conditions precedent set forth in Section 2, and each US Lender shall be obligated to pay its US Pro Rata Share thereof in accordance with the Agreement. In the event that Canadian Agent or a Canadian Lender shall make any payment on or pursuant to any Canadian Letter of Credit Obligation, such payment shall then be deemed automatically to constitute a Canadian Revolving Credit Advance to the Canadian Borrower for whose account such Canadian Letter of Credit Obligation was incurred, regardless of whether a Default or an Event of Default has occurred and is continuing and notwithstanding Canadian Borrowers’ failure to satisfy the conditions precedent set forth in Section 2, and each Canadian Lender shall be obligated to pay its Canadian Pro Rata Share thereof in accordance with the Agreement. The failure of any Lender to make available to the Applicable Agent its applicable Pro Rata Share of any such Revolving Credit Advance or payment by the Applicable Agent under or in respect of a Letter of Credit shall not relieve any other applicable Lender of its obligation hereunder to make available to the Applicable Agent its applicable Pro Rata Share thereof, but no Lender shall be responsible for the failure of any other Lender to make available such other Lender’s applicable Pro Rata Share of any such payment.

               (ii) If it shall be illegal or unlawful for US Borrowers to incur US Revolving Credit Advances or for Canadian Borrowers to incur Canadian Revolving Credit Advances as contemplated by paragraph (b)(i) above because of an Event of Default described in Section 8.1(h) or (i) or otherwise or if it shall be illegal or unlawful for any Lender to be deemed to have assumed a ratable share of the reimbursement obligations owed to an L/C Issuer, or if the L/C Issuer is a Lender, then (A) immediately and without further action whatsoever, each applicable Lender shall be deemed to have irrevocably and unconditionally purchased from Applicable Agent (or such L/C Issuer, as the case may be) an undivided interest and participation equal to such applicable Lender’s applicable Pro Rata Share (based on the applicable Commitment(s)) of the applicable Letter of Credit Obligations in respect of all applicable Letters of Credit then outstanding and (B) thereafter, immediately upon issuance of any Letter of Credit, each applicable Lender shall be deemed to have irrevocably and unconditionally purchased from Applicable Agent (or such L/C Issuer, as the case may be) an undivided interest and participation in such applicable Lender’s Pro Rata Share (based on the applicable Commitment(s)) of the applicable Letter of Credit Obligations with respect to such Letter of Credit on the date of such issuance. Each Lender shall fund its participation in all payments or disbursements made under the Letters of Credit in the same manner as provided in the Agreement with respect to Revolving Credit Advances.

          (c) Cash Collateral.

               (i) If US Borrowers or Canadian Borrowers are required to provide cash collateral for any Letter of Credit Obligations pursuant to the Agreement prior to the Commitment Termination Date, US Borrowers will pay to Agent in respect of US Letters of Credit, and Canadian Borrowers will pay to Canadian Agent in respect of Canadian Letters of Credit, for the ratable benefit of the applicable Borrowers and applicable Lenders, cash or cash equivalents acceptable to such Applicable Agent (“Cash Equivalents”) in an amount equal to 105% of the maximum amount then available to be drawn under each applicable Letter of Credit outstanding for the benefit of such Borrower(s). Such funds or Cash Equivalents shall be held by

the Applicable Agent in a cash collateral account (each, a “Cash Collateral Account”) maintained at a bank or financial institution acceptable to the Applicable Agent. The Cash Collateral Accounts shall be in the names of the applicable Borrowers and shall be pledged to, and subject to the control of, the Applicable Agent, for the benefit of the Agents and the Lenders, in a manner satisfactory to the Applicable Agent. US Borrowers hereby pledge and grant to Agent, on behalf of Agents and Lenders, security interests in all such funds and Cash Equivalents held from time to time in the Cash Collateral Account established by Agent and all proceeds thereof, as security for the payment of all amounts due in respect of the US Letter of Credit Obligations and other Obligations, whether or not then due. Canadian Borrowers hereby pledge and grant to Canadian Agent, on behalf of Agents and Canadian Lenders, a security interest in all such funds and Cash Equivalents held from time to time in the Cash Collateral Accounts established by the Canadian Agent and all proceeds thereof, as security for the payment of all amounts due in respect of the Canadian Letter of Credit Obligations and other Obligations, whether or not then due. The Agreement, including this Annex B, shall constitute a security agreement under applicable law.

               (ii) If any Letter of Credit Obligations, whether or not then due and payable, shall for any reason be outstanding on the Commitment Termination Date, US Borrowers, in the case of US Letter of Credit Obligations, and Canadian Borrowers, in the case of Canadian Letter of Credit Obligations, shall either (A) provide cash collateral therefor in the manner described above, or (B) cause all related Letters of Credit and guaranties thereof, if any, to be cancelled and returned, or (C) deliver a stand-by letter (or letters) of credit in guaranty of such Letter of Credit Obligations, which stand-by letter (or letters) of credit shall be of like tenor and duration (plus 30 additional days) as, and in an amount equal to 105% of, the aggregate maximum amount then available to be drawn under, the Letters of Credit to which such outstanding Letter of Credit Obligations relate and shall be issued by a Person, and shall be subject to such terms and conditions, as may be satisfactory to the Applicable Agent in its sole discretion.

               (iii) From time to time after funds are deposited in a Cash Collateral Account by any Borrower, whether before or after the Commitment Termination Date, the Applicable Agent may apply such funds or Cash Equivalents then held in such Cash Collateral Account established by it to the payment of any amounts, and in such order as such Agent may elect, as shall be or shall become due and payable by such Borrower to such Applicable Agent and applicable Lenders with respect to Letter of Credit Obligations and, upon the satisfaction in full of all applicable Letter of Credit Obligations, to any other Obligations in accordance with the Agreement.

               (iv) No Borrower nor any Person claiming on behalf of or through any Borrower shall have any right to withdraw any of the funds or Cash Equivalents held in any Cash Collateral Account, except that upon the termination of all Letter of Credit Obligations and the payment of all amounts payable by all Borrowers to Agents and Lenders in respect thereof, any funds remaining in the Cash Collateral Accounts shall be applied to other Obligations then due and owing and upon payment in full of such Obligations, any remaining amount shall be paid to Borrowers or as otherwise required by law. Interest earned on deposits in the Cash Collateral Accounts shall contribute additional cash collateral.

          (d) Fees and Expenses. US Borrowers agree to pay to the Agent for the benefit of Agent and US Lenders, and Canadian Borrowers agree to pay to the Canadian Agent, for the benefit of Canadian Agent and the Canadian Lenders, as compensation to such Lenders for Letter of Credit Obligations incurred by them hereunder, (i) all reasonable costs and expenses incurred by the Applicable Agent or any applicable Lender on account of such Letter of Credit Obligations, and (ii) for each month during which any Letter of Credit Obligation shall remain outstanding, a fee (the “Letter of Credit Fee”) in an amount equal to the Applicable L/C Margin from time to time in effect multiplied by the maximum amount available from time to time to be drawn under the applicable Letter of Credit. Such fee shall be paid to the Applicable Agent for the benefit of the applicable Lenders in arrears, on the first day of each month and on the Commitment Termination Date. In addition, the US Borrowers and the Canadian Borrowers, as applicable, shall pay to any L/C Issuer, on demand, such fees (including all per annum fees), charges and expenses of such L/C Issuer in respect of the issuance, negotiation, acceptance, amendment, transfer and payment of such Letter of Credit issued for their respective accounts or otherwise payable pursuant to the application and related documentation under which such Letter of Credit is issued.

          (e) Request for Incurrence of Letter of Credit Obligations. Borrower Representative shall give Agent, in the case of US Letters of Credit, and both Agents, in the case of Canadian Letters of Credit, at least 2 Business Days’ prior written notice requesting the incurrence of any Letter of Credit Obligation. The notice shall be accompanied by the form of the Letter of Credit (which shall be acceptable to the L/C Issuer) and a completed Application for Standby Letter of Credit or Application and Agreement for Documentary Letter of Credit or Application for Documentary Letter of Credit as applicable in the form of Exhibit B1 or B2 or B3 attached hereto or such other documentation as the Applicable Agent and the L/C Issuer shall require. Notwithstanding anything contained herein to the contrary, Letter of Credit applications by Borrower Representative and approvals by the Applicable Agent and the L/C Issuer may be made and transmitted pursuant to electronic codes and security measures mutually agreed upon and established by and among the Borrower Representative and Applicable Agent and the applicable L/C Issuer.

          (f) Obligation Absolute. The obligations of US Borrowers to reimburse Agent and US Lenders, and the Canadian Borrowers to reimburse Canadian Agent and Canadian Lenders, for payments made with respect to any Letter of Credit Obligation shall be absolute, unconditional and irrevocable, without necessity of presentment, demand, protest or other formalities, and the obligations of each applicable Lender to make payments to each Applicable Agent with respect to Letters of Credit shall be unconditional and irrevocable. Such obligations shall be paid strictly in accordance with the terms hereof under all circumstances including the following:

               (i) any lack of validity or enforceability of any Letter of Credit or the Agreement or the other Loan Documents or any other agreement;

               (ii) the existence of any claim, setoff, defense or other right that any Borrower or any of their respective Affiliates or any Lender may at any time have against a beneficiary or any transferee of any Letter of Credit (or any Persons or entities for whom any

such transferee may be acting), one or more Agents, any Lender, or any other Person, whether in connection with the Agreement, the Letter of Credit, the transactions contemplated herein or therein or any unrelated transaction (including any underlying transaction between any Borrower or any of their respective Affiliates and the beneficiary for which the Letter of Credit was procured);

               (iii) any draft, demand, certificate or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

               (iv) payment by any Applicable Agent (except as otherwise expressly provided in paragraph (g)(ii)(C) below) or any L/C Issuer under any Letter of Credit or guaranty thereof against presentation of a demand, draft or certificate or other document that does not comply with the terms of such Letter of Credit or such guaranty;

               (v) any other circumstance or event whatsoever, that is similar to any of the foregoing; or

               (vi) the fact that a Default or an Event of Default has occurred and is continuing.

          (g) Indemnification; Nature of Lenders’ Duties.

               (i) In addition to amounts payable as elsewhere provided in the Agreement, each of the Borrowers, jointly and severally, hereby agrees to pay and to protect, indemnify, and save harmless each Agent and each Lender from and against any and all claims, demands, liabilities, damages, losses, costs, charges and expenses (including reasonable attorneys’ fees and allocated costs of internal counsel) that one or more Agents may incur or be subject to as a consequence, direct or indirect, of (A) the issuance of any Letter of Credit or guaranty thereof, or (B) the failure of one or more Agents or any Lender seeking indemnification or of any L/C Issuer to honor a demand for payment under any Letter of Credit or guaranty thereof as a result of any act or omission, whether rightful or wrongful, of any present or future de jure or de facto government or Governmental Authority, in each case, other than to the extent solely as a result of the gross negligence or willful misconduct of such Agent or such Lender (as finally determined by a court of competent jurisdiction); provided, however, that no cash or assets of any Canadian Credit Party shall be applied, directly or indirectly, to the Obligations of the US Borrowers.

               (ii) As between one or more Agents and any Lender and Borrowers, Borrowers assume all risks of the acts and omissions of, or misuse of any Letter of Credit by beneficiaries, of any Letter of Credit. In furtherance and not in limitation of the foregoing, to the fullest extent permitted by law, neither Agent nor any Lender shall be responsible for: (A) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document issued by any party in connection with the application for and issuance of any Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (B) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or

assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, that may prove to be invalid or ineffective for any reason; (C) failure of the beneficiary of any Letter of Credit to comply fully with conditions required in order to demand payment under such Letter of Credit; provided, that in the case of any payment by any Applicable Agent under any Letter of Credit or guaranty thereof, such Agent shall be liable to the extent such payment was made solely as a result of its gross negligence or willful misconduct (as finally determined by a court of competent jurisdiction) in determining that the demand for payment under such Letter of Credit or guaranty thereof complies on its face with any applicable requirements for a demand for payment under such Letter of Credit or guaranty thereof; (D) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, whether or not they may be in cipher; (E) errors in interpretation of technical terms; (F) any loss or delay in the transmission or otherwise of any document required in order to make a payment under any Letter of Credit or guaranty thereof or of the proceeds thereof; (G) the credit of the proceeds of any drawing under any Letter of Credit or guaranty thereof; and (H) any consequences arising from causes beyond the control of the Applicable Agent or any Lender. None of the above shall affect, impair, or prevent the vesting of one or more Agents’ or any Lender’s rights or powers hereunder or under the Agreement.

               (iii) Nothing contained herein shall be deemed to limit or to expand any waivers, covenants or indemnities made by any Borrower in favor of any L/C Issuer in any letter of credit application, reimbursement agreement or similar document, instrument or agreement between or among such Borrower and such L/C Issuer, including an Application and Agreement for Documentary Letter of Credit or a Master Documentary Agreement and a Master Standby Agreement entered into with one or more Agents.
