Re: Rule Certification. NYMEX Submission 05-160: Notification of Approved
Amendment to Supplement No. 1, “Official List of Approved Refiners and
Brands” of the Gold Futures Contract and Silver 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 Refiners and Brands” of the Gold
Futures Contract and Silver Futures Contract to be implemented effective Tuesday, September
13, 2005. The approved amendment changes the production status of the gold and silver brand
“JOHNSON MATTHEY LONDON?” produced by Johnson Matthey to no longer produced. The
brand will be marked with an asterisk (*) to indicate that it is no longer produced. The
“JOHNSON MATTHEY LONDON” brand will continue to remain acceptable for delivery
against the Gold Futures Contract and Silver Futures Contract since there are gold and silver bars
bearing this brand in Exchange Licensed Depositories.

Pursuant to Section 5c(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 Tuesday, September
13, 2005.
