C.P. 03020 Mexico, D.F.

Dear Mr. Alvarez Hoth:

Consistent with Articles IV and V of the Agreement Between the Government of

the United States of America and the Government of the United Mexican States

Concerning the Allocation and Use of Frequency Bands by Terrestrial Non-Broadcasting

Radiocommunication Services Along the Common Border signed at Williamsburg,

Virginia on June 16, 1994, (the "Agreement"), the National Telecommunications and

Information Administration of the Department of Commerce of the United States of

America ("NTIA"), the designated Administration for the United States under Article II,

paragraph 1 of the Protocol Between the Department of State of the United States of

America and the Secretaria de Comunicaciones y Transportes of the United Mexican

States Concerning the Allotment and Use of the 380-399.9 MHz Band for Fixed and

Mobile Terrestrial Non-Broadcasting Services Along the Common Border, signed at

Mexico City on July 27, 2005 (the "2005 Protocol"), has the honor to propose that the

2005 Protocol be amended as follows:

1. In Article I, paragraph 1, a semicolon and an "and" is added at the end of

subparagraph b. and the following is inserted thereafter:

"c. To allow for temporary cross-border communications on an

interim basis as set forth under Article IV, paragraph 3, herein."

2. In Article II, the title of Article II is amended to read as follows: "Designation

of Administrations and Definitions." Also, in Article II, paragraph 1 is amended to

read as follows: "The National Telecommunications and Information Administration of

the Department of Commerce United States of America and the Secretaria de
Comunicaciones y Transportes of the United Mexican States are hereby designated the

Administrations responsible for the implementation of this Protocol for the United States

of America (hereinafter "United States") and the United Mexican States (hereinafter

"Mexico"), respectively, as provided for in Article IV of the Agreement."

3. In Article IV, at the end of paragraph 2, a new paragraph 3 is inserted

thereafter as follows:

"3. Notwithstanding Article IV, paragraph 1 herein, which limits new

assignments to primary allotments for each Administration, new assignments on the

frequencies and their associated bandwidths shown in Appendix III are allowed on a

temporary basis at certain stations in the United States so that those U.S. stations may

engage in cross-border communications with counter-part stations in Mexico. Those U.S.

stations are located in the State of Arizona in the United States and are identified in

Appendix IV of this Protocol. Appendix IV also lists the counter-part stations in Mexico.

Such temporary new assignments are not allowed on other U.S. stations in any of the

border states of the United States.

a. The U.S. Administration may make new temporary assignments to

the U.S. stations listed in Appendix IV under the exception set forth in this paragraph

only on the condition that no harmful interference is caused to stations in Mexico. In the

case of harmful interference to the U.S. stations listed in Appendix IV from Mexican

stations, the U.S. Administration will request cooperation from the Mexican

Administration in order to ensure viable direct cross-border communications between the

stations in each country.
b. The limited temporary use permitted under the terms set forth in

the prior provisions of this paragraph may continue only until the two Administrations

either find and agree upon an alternative radio-frequency band for the assigned use or

until July 1, 2008, whichever occurs first. If the two Administrations agree upon an

alternative radio-frequency band for the assigned use for any U.S. station prior to July 1,

2008, the limited temporary use of the frequencies by that U.S. station shall end when

cross-border operations are deployed and transmissions by that U.S. station begins on the

alternative frequency band.

4. Article V is amended to read as follows: "Appendices I, II, III and IV are an

integral part of this Protocol."

5. Appendix I, Table II, Decimal Degrees in the Right Column for Point 1 is

amended to read: "32.2378N"

6. Following Appendix II, new Appendices III and IV are inserted thereafter as

follows:

"APPENDIX III

382.3000 392.3000

Each frequency employs an associated bandwidth of plus and minus 12.5 kHz relative to

the center carrier frequency, i.e. 382.2875-382.3125 MHz and 392.2875-392.3125 MHz.

5 All frequencies in MHz

6 These two frequencies and their associated bandwidths are designated as primary for

new assignments by Mexico and may also be assigned for temporary cross-border use

only as set forth in Article IV, paragraph 3, to the U.S. stations listed in Appendix IV of

this Protocol."
