Re: Rule Certification. NYMEX Submission 05-97: Notification of Approved
Amendment to Supplement No. 1, “Official List of Approved Brands and
Markings” of the Grade 1 Copper Futures Contract.

Dear CFTC Commissioners:

The New York Mercantile Exchange, Inc. ("NYMEX" or the "Exchange") is notifying the
Commodity Futures Trading Commission (“CFTC” or “Commission”) of an approved
amendment to Supplement No. 1, “Official List of Approved Brands and Markings” of the Grade
1 Copper Futures Contract to be implemented effective Monday, June 6, 2005. The approved
amendment changes the name of the producer of the “ENM” brand of copper cathode from
Empresa Nacional de Mineria (“ENAMI”) to Corporacion Nacional del Cobre de Chile
(“CODELCO”). CODELCO, the world’s largest copper producer, acquired from ENAMI all of
the Las Ventanas Refinery located in the Fifth Region of Chile which produces the “ENM” brand
of copper cathodes. The brand insignia remains unchanged.

Pursuant to Section Sc(c) of the Commodity Exchange Act (“Act”) and CFTC Rule 40.6, the
Exchange hereby certifies that the attached rule amendment complies with the Act, including

regulations under the Act. This approved amendment will go into effect on Monday, June 6,
2005.

Should you have any questions concerning the above, please contact Albert J. Getz at (212) 299-
2608.

Very truly yours,

Robert A. Levin
