    2. Canadian operational requirements can be satisfied by 4 channels,
    3. Canada and the U.S.A. will use one shared channel, the following channelling arrangement is agreed:

      Canadian channels: 24, 85, 27, 88Footnote 1
      U.S. channels: 84, 25, 86, 87, 28Footnote 2
      Shared channel: 26Footnote 3

  4. In adopting the above arrangement, it is understood that each Administration has complete flexibility in making use of its channels within the frequency coordination zone; that the option provided by footnotes 1) and 2) should not be exercised unless the proposed assignment cannot be accommodated on a channel allotted under the plan; that an assignment made under the provisions of footnote 1) or 2) should not be a bar to future utilization of the channel by the Administration to which it is allotted under this arrangement; and that such an assignment will be vacated if requested by the Administration to which the channel is allotted.
  5. This arrangement, which is subject to periodic review at the request of either Administration, supersedes the provisions set forth in the Canada/U.S.A. Exchanges of Letters dated December 10 and 16, 1965, and January 9 and June 8, 1973, insofar as they pertain to the use of the public correspondence channels stipulated in paragraph 3 above, in the area described in paragraph 1 above.
