Amendments to NYMEX Rule 11G.23 ("EFBs"), Rule 11G.22 ("EFMs"), and Deletion of Rule 6.21E, ("EFMs")
Please find attached modifications to NYMEX Rule 11G.23, Exchange of NYMEX Cash-Settled "Penultimate Big" Futures for, or in Connection with, NYMEX "Physical" Futures Transactions ("EFBs"); Rule 11G.22, Exchange of NYMEX miNY Futures for, or in Connection with, NYMEX Futures Transactions ("EFMs"); and deletion of Rule 6.21E, Exchange of NYMEX miNY Futures for, or in Connection with, NYMEX Futures Transactions.

The changes seek to allow for the posting of any eligible EFMs or EFBs available at a differential to the prior day's settlement price in addition to the settlement price itself. Further, the amendments seek to allow these transactions to be posted through expiration day of the underlying miNY or cash-settled "big" contracts. The Exchange is deleting Rule 6.21E as this Rule is mirrored in Rule 11G.22. The changes, which are effective June 29, 2006, are housekeeping in nature, and in keeping with prior determinations of the NYMEX Board of Directors.
