Madam,

I have the honour to refer to your Note, dated July 9, 1997, with its attachment, which reads as follows:

"I have the honor to refer to the Exchange of Notes (November 26, 1990 and February 25, 1991) constituting an Agreement between the Government of the United States of America and the Government of Canada concerning the use of the 88 to 108 megahertz frequency band for frequency modulation broadcasting (FM) (hereinafter referred to as the "1991 Agreement") and to discussions between representatives of both Governments concerning revisions to the Working Arrangement "Working Arrangement for the allotment and assignment of FM broadcasting channels under the Agreement between the Government of Canada and the Government of the United States of America relating to the FM broadcasting service", which forms an integral part of that Agreement. In the interests of improved use of the FM Broadcasting Band, I propose that certain provisions of the Working Arrangement for the allotment and assignment of FM broadcasting channels be amended in accordance with the attachment to this Note.

Accordingly, I propose that this Note, with its attachment, and your affirmative reply, shall constitute an Agreement to amend the 1991 Agreement which shall enter into force on the date of your reply.

Accept, Excellency, the renewed assurances of my highest consideration."

I have the further honour to inform you that the Government of Canada accepts the proposals contained in your Note and attachment. Accordingly, your Note and this reply, which is equally authentic in English and French, shall constitute an Agreement to amend the 1991 Agreement which shall enter into force on the date of this Note.

Accept the renewed assurances of my highest consideration.
