Dear Sirs/Madames:

Re: Amendment to Credit Facility

Power Measurement Ltd. (the "Borrower") has requested certain amendments to the Credit Agreement dated as of March 12, 1999 (as amended, supplemented, or otherwise modified from time to time) among the Borrower, as borrower, Canadian Imperial Bank of Commerce (the "Agent"), as agent and Canadian Imperial Bank of Commerce, and such lenders as are from time to time signatories thereto (collectively, the "Lenders") (the "Credit Agreement", the capitalized terms used herein as therein defined). In consideration of the continued advance of the credit facilities under the Credit Agreement, the Agent for and on behalf of itself and as Lender, the Borrower and the subordinated lenders listed in Schedule A (the "Subordinated Lenders") agree that the Credit Agreement shall be deemed to be amended so as to;

(i): pursuant to Section 7.1(r) delete the last sentence, "In addition, the Investors maintain an investment by way of Subordinated Debt in the Borrower in the amount of not less than $7,200,000 pursuant to the Notes."; and
(ii): delete in it's entirety Section 9.1(v)(iv).
(ii): increase the amount of Borrower's Shareholder Equity required pursuant to Section 9.1(a)(iii) of the Credit Agreement by Cdn.$7,200,000 so that the amount then reads: "as at the last day of each month, the Borrower's Shareholder Equity shall not be less than Cdn.$37,200,000 plus 75% of annual positive net earnings and 100% of the proceeds of any offering of Securities;"

and any and all necessary changes in connection with the foregoing amendments shall be deemed to have been made to the Credit Facility Documents.

The parties acknowledge that save as otherwise indicated herein, the Credit Agreement and Credit Facility Documents shall continue unamended and remain in full force and effect and except as amended and supplemented hereby and in the amendment agreements dated December 6, 1999 and January 1, 2001, and the Security and the other Credit Facility Documents are in all respects confirmed, ratified and preserved.

The Borrower and each of the Subordinated Lenders shall, and the Borrower shall cause its Material Subsidiaries to, at all times hereafter at the reasonable request of the Agent for and on behalf of the Lenders execute and deliver to the Agent all such further documents and instruments and shall do and perform such acts as may be necessary to give full effect to the intent and meaning of this letter including without limitation, all such further documents, certificates and instruments as considered necessary or desirable by any of the Lenders to preserve, protect or perfect the Security and the Borrower acknowledges and agrees that a default hereunder shall constitute a Default and Event of Default under the Credit Agreement.

This letter shall be binding upon the Borrower and the Subordinated Lenders and their respective successors and permitted assigns and shall enure to the benefit of the Agent and the Lenders and their respective successors and assigns and shall be governed by the laws of the Province of British Columbia and the laws of Canada applicable therein.

If the foregoing is consistent with your understanding and is acceptable to you, please execute a copy of this letter and return it to us.

	Yours truly,
	CANADIAN IMPERIAL BANK OF COMMERCE, as Agent and Lender
