(e) Section 2.13(j) of the Credit Agreement is hereby amended and restated in its entirety as follows: (j) All interest hereunder (except for interest denominated in Sterling, which shall be computed on the basis of a year of 365 days) shall be computed on the basis of a year of 360 days, except that interest computed by reference to the CB Floating Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). For the purposes of the Interest Act (Canada) and disclosure thereunder, (i) whenever any interest under this Agreement or any other Loan Documents is calculated using a rate based on a year of 360 days, the rate determined pursuant to such calculation, when expressed as an annual rate, is equivalent to (x) the applicable rate, (y) multiplied by the actual number of days in the calendar year in which the period for which such interest is payable (or compounded) ends, and (z) divided by 360; (ii) the principle of deemed reinvestment of interest does not apply to any interest calculation under this Agreement; and (iii) the rates of interest stipulated in this Agreement are intended to be nominal rates and not effective rates or yields. The applicable CB Floating Rate, Adjusted LIBO Rate, REVLIBOR30 Rate, LIBO Rate or Overnight LIBO Rate shall be determined by the Administrative Agent and the applicable Canadian Prime Rate, US Base Rate (Canada) or CDOR Rate shall be determined by the Canadian Agent, and each such determination shall be conclusive absent manifest error. (f) The Credit Agreement is hereby amended to insert a new Schedule 2.1.3 (Rollover Letters of Credit) in the form of Schedule 2.1.3 attached hereto. (g) The Credit Agreement is hereby amended to include a new Section 9.25 as follows: SECTION 9.25. Acknowledgement Regarding Any Supported QFCs.

-7- effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. 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. 2.

This Amendment constitutes a Loan Document. 7. Severability. Any provision of this Amendment held by a court of competent jurisdiction to be invalid or unenforceable shall not impair or invalidate the remainder of this Amendment and the effect thereof shall be confined to the provision so held to be invalid or unenforceable. 8. References. Any reference to the Credit Agreement contained in any document, instrument or Credit Agreement executed in connection with the Credit Agreement shall be deemed to be a reference to the Credit Agreement as modified by this Amendment. 9. Counterparts. This Amendment may be executed in one or more counterparts, each of which shall constitute an original, but all of which taken together shall be one and the same instrument.

Whenever possible each provision of this Amendment shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Amendment shall be prohibited by or invalid under such law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Amendment.
