Rule Certification
Dear Ms. Webb:

Pursuant to Commission Regulation 40.6(a), the Chicago Board of Trade (CBOT®) hereby
submits the following:

- Amendments to Regulation m1544.01 per the attached text (additions underlined;
deletions struck through).

The referenced regulation governs delivery of Gold by Warehouse Depository Receipts (WDRs)
for CBOT mini-sized Gold futures. The amendments address the exchange of WDRs for 100
ounce or Kilo Gold receipts. Specifically, the amendments will clarify that mini-sized Gold
WDRs must be exchanged in groups of three (3), either for one 100 ounce receipt or one 3 Kilo
receipt, as determined by the Exchange Registrar.

The CBOT intends to implement these amendments no sooner than one day after the
Commission’s receipt of this filing.

There were no opposing views concerning these amendments.

The CBOT certifies that these amendments comply with the Commodity Exchange Act and the
rules thereunder.

Sincerely,

Paul J. Draths
Vice President and Secretary

m1544.01 Form-of Deliveries by Gold Warehouse Depository Receipts — Deliveries of CBOT mini-
sized Gold shall be made by delivery of Warehouse Depository Receipts (WDR) created by the Exchange from
registered vault receipts issued by vaults against inventory of Gold in vaults which have been declared regular
for delivery of Gold by the Exchange. In order to effect a valid delivery, each WDR must be properly endorsed
by the holder making the delivery. Such endorsement shall constitute a warranty of the genuineness of the
WDR and of good title thereto, but shall not constitute a quaranty, by an endorser, of performance by the vault.
Such endorsement _shall_also_constitute_a representation that all storage charges have been paid on the
commodity covered by the WDR, in accordance with Requlation m1556.01 _. Upon the return of three (3)
properly endorsed WDRs to the Exchange, and payment of all storage charges pertaining to the Gold
represented, for which the Exchange claims a lien, a vault receipt that meets the delivery specifications of the
CBOT will be delivered by the Exchange to the holder of the three (3) WDRs.

The following form of warehouse depository receipt shall be used:
