WHEREAS, the Borrowers have requested that the Agent, the Issuing Banks and the Required Lenders effect certain amendments to the Credit Agreement as more specifically set forth herein, and the Agent, the Issuing Banks and the Required Lenders are willing to effect such amendments to the Credit Agreement on the terms and conditions hereinafter set forth.
NOW, THEREFORE, in consideration of the foregoing and the mutual covenants herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties signatory hereto agree as follows:

“Alternative Currency: any currency (other than Dollars and Canadian Dollars) which the U.S. Borrower, the Agent, and Bank of America (as Issuing Bank) agree in their sole discretion to include as a currency in which a U.S. Letter of Credit may be issued; provided that such requested currency is an Eligible Currency.
Eligible Currency: means any lawful currency other than Dollars and Canadian Dollars that is readily available, freely transferable and convertible into Dollars in the international interbank market available to the applicable Issuing Bank in such market and as to which a Dollar Equivalent may be readily calculated. If, after the designation by the Agent and the applicable Issuing Bank of any currency as an Alternative Currency, any change in currency controls or exchange regulations, or any change in the national or international financial, political or economic conditions imposed in the country in which such currency is issued, results in, in the reasonable opinion of the applicable Issuing Bank, (a) such currency no longer being readily available, freely transferable and convertible into Dollars, (b) a Dollar Equivalent no longer being readily calculable with respect to such currency, (c) providing such currency no longer being practicable for the Issuing Bank or (d) such currency no longer being a currency in which the applicable Issuing Bank is willing, in its sole discretion, to make issuances, fundings, disbursements, settlements and payments in respect of any Letter of Credit (each of the foregoing clauses, a “Disqualifying Event”), then such Issuing Bank shall promptly notify the Agent and the U.S. Borrower, and such country’s currency shall no longer be an Alternative Currency until such time as the Disqualifying Event(s) no longer exist. Within five (5) Business Days after receipt of such notice from the applicable Issuing Bank, the U.S. Borrower shall Cash Collateralize that portion of the LC Obligations comprised of the aggregate undrawn amount of Letters of Credit to the extent not otherwise Cash Collateralized.”

Any division of a limited liability company shall constitute a separate Person hereunder (and each division of any limited liability company that is a Subsidiary, joint venture or any other like term shall also constitute such a Person or entity).”

EXHIBIT 4.34J
(e)Section 2.2.1 of the Credit Agreement is hereby amended by deleting such subsection in its entirety and inserting in lieu thereof the following:
“Issuance of Letters of Credit. U.S. Issuing Bank agrees to issue letters of credit for the account of the U.S. Borrower (“U.S. Letters of Credit”) from time to time until (x) fifteen (15) Business Days prior to the Facility Termination Date (or until the U.S. Revolver Commitment Termination Date, if earlier) or (y) with the consent of the Agent and U.S. Issuing Bank, the Facility Termination Date (or until the U.S. Revolver Commitment Termination Date, if earlier), on the terms set forth herein, including the following:”
(f)Section 2.2.1(a) of the Credit Agreement is hereby amended by deleting such subsection in its entirety and inserting in lieu thereof the following:
“(a) The U.S. Borrower acknowledges that U.S. Issuing Bank’s willingness to issue any U.S. Letter of Credit is conditioned upon U.S. Issuing Bank’s receipt of an LC Application with respect to the requested U.S. Letter of Credit, as well as such other instruments and agreements as U.S. Issuing Bank may customarily require for issuance of a letter of credit of similar type and amount. U.S. Issuing Bank shall have no obligation to issue any U.S. Letter of Credit unless (i) U.S. Issuing Bank receives an LC Request and LC Application at least three (3) Business Days prior to the requested date of issuance; (ii) each LC Condition is satisfied; (iii) if a Defaulting Lender that is a U.S. Lender exists, such Defaulting Lender or the U.S. Borrower have entered into arrangements satisfactory to the Agent and U.S. Issuing Bank to eliminate any funding risk associated with such Defaulting Lender (it being understood that Cash Collateralization of a Defaulting Lender’s Pro Rata share of the requested U.S. Letter of Credit is satisfactory to the Agent and U.S. Issuing Bank); and (iv) with respect to an Alternative Currency, such U.S. Issuing Bank does, as of the issuance date of the requested U.S. Letter of Credit, issue Letters of Credit in the requested currency. If U.S. Issuing Bank receives written notice from a U.S. Lender at least five (5) Business Days before the requested date of issuance of a U.S. Letter of Credit that any LC Condition has not been satisfied, U.S. Issuing Bank shall have no obligation to issue the requested U.S. Letter of Credit (or any other) until such notice is withdrawn in writing by that Lender or until the Required Facility Lenders have waived such condition in accordance with this Agreement. Prior to receipt of any such notice, U.S. Issuing Bank shall not be deemed to have knowledge of any failure of LC Conditions. No U.S. Letter of Credit denominated in any Alternative Currency may be issued by any U.S. Issuing Bank other than Bank of America or an Affiliate of Bank of America.”
(g)Section 2.2.1(b) of the Credit Agreement is hereby amended by deleting such subsection in its entirety and inserting in lieu thereof the following:
“(b) Letters of Credit may be requested by the U.S. Borrower only (i) to support obligations of a U.S. Domiciled Loan Party incurred in the Ordinary Course of Business; or (ii) for other purposes as the Agent may approve from time to time in writing. The renewal or extension of any U.S. Letter of Credit shall be treated as the issuance of a new U.S. Letter of Credit, except that delivery of a new LC Application may be required at the discretion of U.S. Issuing Bank. Notwithstanding that a U.S. Letter of Credit issued or outstanding hereunder is in support of obligations of a U.S. Domiciled Loan Party incurred in the Ordinary Course of Business or for other purposes as the Agent may approve from time to time in writing, the U.S. Borrower shall be obligated to reimburse, indemnify and compensate the applicable Issuing Bank hereunder for any and all drawings under such Letter of Credit as if such Letter of Credit had been issued solely for the account of the U.S. Borrower. The U.S. Borrower irrevocably waives any and all defenses that might otherwise be available to it as a guarantor or surety of any or all of the obligations of any such U.S. Domiciled Loan Party or other Subsidiary in respect of such Letter of Credit. The U.S. Borrower hereby acknowledges that the issuance of U.S. Letters of Credit for the account of U.S. Domiciled Loan Parties or other Subsidiaries inures to the benefit of the U.S. Borrower, and that the U.S. Borrower’s business derives substantial benefits from the businesses of such U.S. Domiciled Loan Parties or other Subsidiaries.”
(h)Section 2.2.2(a) of the Credit Agreement is hereby amended by deleting such subsection in its entirety and inserting in lieu thereof the following:
“(a) If U.S. Issuing Bank honors any request for payment under a U.S. Letter of Credit, the U.S. Borrower shall pay to U.S. Issuing Bank, on the same day (“U.S. Reimbursement Date”), the amount paid by U.S. Issuing Bank under such U.S. Letter of Credit, together with interest at the interest rate for U.S. Base Rate Loans from the U.S. Reimbursement Date until payment by the U.S. Borrower. The U.S. Borrower shall make such payment to the applicable U.S. Issuing Bank in Dollars, unless, in the case of a Letter of Credit denominated in Canadian Dollars or an Alternative Currency, such Issuing Bank (at its option) shall have specified in such notice that it

EXHIBIT 4.34J
will require reimbursement in Canadian Dollars or the applicable Alternative Currency. In the case of any such reimbursement in Dollars of a drawing under a Letter of Credit denominated in Canadian Dollars or an Alternative Currency, the applicable U.S. Issuing Bank shall notify the U.S. Borrower of the Dollar Equivalent of the amount of the drawing promptly following the determination thereof. On each U.S. Reimbursement Date, the U.S. Borrower shall reimburse such U.S. Issuing Bank in an amount equal to the amount of such drawing and in the applicable currency. In the event that (i) a drawing denominated in Canadian Dollars or an Alternative Currency is to be reimbursed in Dollars and (ii) the Dollar amount paid by the U.S. Borrower, whether on or after the U.S. Reimbursement Date, shall not be adequate on the date of that payment to purchase in accordance with normal banking procedures a sum denominated in the Alternative Currency equal to the drawing, the U.S. Borrower agrees, as a separate and independent obligation, to indemnify the applicable U.S. Issuing Bank for the loss resulting from its inability on that date to purchase the Alternative Currency in the full amount of the drawing. The obligation of the U.S. Borrower to reimburse U.S. Issuing Bank for any payment made under a U.S. Letter of Credit shall be absolute, unconditional and irrevocable, and shall be paid under any and all circumstances whatsoever without regard to any lack of validity or enforceability of any such U.S. Letter of Credit, any adverse change in the relevant exchange rates or in the availability of any relevant Alternative Currency to the U.S. Borrower or in the relevant currency markets generally, the existence of any claim, setoff, defense or other right that the U.S. Borrower or any other U.S. Domiciled Loan Parties may have at any time against the beneficiary, or any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the U.S. Borrower’s obligations hereunder. Whether or not the Loan Party Agent submits a Notice of Borrowing, the U.S. Borrower shall be deemed to have requested a Borrowing of U.S. Base Rate Loans in an amount necessary to pay all amounts due U.S. Issuing Bank on any U.S. Reimbursement Date and each U.S. Lender agrees to fund its Pro Rata share of such Borrowing whether or not the U.S. Revolver Commitments have terminated, any U.S. Overadvance exists or is created thereby, or the conditions in Section 6 are satisfied.”
(i)Section 2.2.2(b) of the Credit Agreement is hereby amended by adding “in Dollars” immediately after “unconditionally pay” appears therein.
(j)Section 2.2.3 of the Credit Agreement is hereby amended by deleting such section in its entirety and inserting in lieu thereof the following:
“2.2.3 Cash Collateral. If any U.S. LC Obligations, whether or not then due or payable, shall for any reason be outstanding at any time (a) that an Event of Default exists, (b) that a U.S. Overadvance exists, (c) after the U.S. Revolver Commitment Termination Date, or (d) within five (5) Business Days prior to the applicable expiry date of the Letters of Credit (if such expiry date is within fifteen (15) Business Days of the Facility Termination Date), then the U.S. Borrower shall, at U.S. Issuing Bank’s or the Agent’s request, Cash Collateralize the stated amount of all outstanding Letters of Credit issued for the account of the U.S. Borrower and pay to U.S. Issuing Bank the amount of all other U.S. LC Obligations. The U.S. Borrower shall, on demand by U.S. Issuing Bank or the Agent from time to time, Cash Collateralize (in Dollars or, if the applicable Letters of Credit were issued in Canadian Dollars or an Alternative Currency and if so requested by the applicable U.S. Issuing Bank (in its sole discretion), Canadian Dollars or such Alternative Currency) the U.S. LC Obligations of any Defaulting Lender that is a U.S. Lender. If the U.S. Borrower fails to provide any Cash Collateral as required hereunder, the U.S. Lenders may (and shall upon direction of the Agent) advance, as U.S. Revolver Loans, the amount of the Cash Collateral required (whether or not the U.S. Revolver Commitments have terminated, any U.S. Overadvance exists or is created thereby or the conditions in Section 6 are satisfied).”

The renewal or extension of any Canadian Letter of Credit shall be treated as the issuance of a new Canadian Letter of Credit, except that delivery of a new LC Application may be required at the discretion of Canadian Issuing Bank. Notwithstanding that a Canadian Letter of Credit issued or outstanding hereunder is in support of obligations of a Canadian Domiciled Loan Party incurred in the Ordinary Course of Business or for other purposes as the Agent may approve from time to time in writing, the Canadian Borrower shall be obligated to reimburse, indemnify and compensate the applicable Issuing Bank hereunder for any and all drawings under such Letter of Credit as if such Letter of Credit had been issued solely for the account of the Canadian Borrower.

In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.
For purposes hereof, the following terms shall have the following meanings:
“BHC Act Affiliate” of a party means an “affiliate” (as such term is defined under, and interpreted in accordance with, 12 U.S.C. 1841(k)) of such party.
“Covered Entity” means any of the following: (a) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (b) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (c) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b).
“Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable.
“QFC” has the meaning assigned to the term “qualified financial contract” in, and shall be interpreted in accordance with, 12 U.S.C. 5390(c)(8)(D).”

5.Effect on Loan Documents. The Credit Agreement and the other Loan Documents, after giving effect to the Fourth Amendment and any other Loan Documents to be executed simultaneously herewith, shall be and remain in full force and effect in accordance with their terms and hereby are ratified and confirmed in all respects. The execution, delivery, and performance of this Fourth Amendment shall not operate as a waiver of any right, power, or remedy of the Agent or any other Secured Party under the Credit Agreement or any other Loan Document, as in effect prior to the date hereof. Each Loan Party hereby ratifies and confirms in all respects all of its obligations (including with respect to Guarantees) and liabilities under the Loan Documents to which it is a party and each Loan Party hereby ratifies and confirms in all respects any prior grant of a security interest under the Loan Documents to which it is party, which security interests shall continue to secure the applicable Obligations (after giving effect to this Fourth Amendment), in each case, on and subject to the terms and conditions set forth in the Credit Agreement and the other Loan Documents.
6.Further Assurances.

Without limiting the generality of the foregoing, each Loan Party waives and affirmatively agrees not to allege or otherwise pursue any defenses, affirmative defenses, counterclaims, claims, causes of action, setoffs or other rights they have or may have under, or in connection with, or otherwise related to, the Loan Documents as of the Effective Date, including, but not limited to, the rights to contest any conduct of Agent, the other Secured Parties or other Releasees on or prior to the Effective Date.

EXHIBIT 4.34J
obligations of the Loan Parties under the Credit Agreement. There are no other understandings, express or implied, among the Loan Parties, the Agent and the other Secured Parties regarding the subject matter hereof or thereof.

10.Counterparts; Facsimile Execution. This Fourth Amendment may be executed in any number of counterparts and by different parties and on separate counterparts, each of which when so executed and delivered shall be deemed an original, and all of which, when taken together, shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Fourth Amendment by facsimile (or other electronic transmission) shall be as effective as delivery of a manually executed counterpart of this Fourth Amendment.
11.Construction. This Fourth Amendment is a Loan Document. This Fourth Amendment and the Credit Agreement shall be construed collectively and in the event that any term, provision or condition of any of such documents is inconsistent with or contradictory to any term, provision or condition of any other such document, the terms, provisions and conditions of this Fourth Amendment shall supersede and control the terms, provisions and conditions of the Credit Agreement.
12.Miscellaneous. The terms and provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their successors and assigns.
