Resumption of the Trading of NYMEX Common Stock / Bundles / Trading Rights
On October 17, 2006, NYMEX ('the Company") announced that in connection with the Company’s initial public offering process, the Board of Directors had determined to temporarily suspend the acceptance and posting of all bids and offers administered by the membership department, for: (i) NYMEX Holdings, Inc. common stock (A1, A2 and A3); (ii) bundled seats (NYMEX Division Class A Membership "trading right" plus 90,000 shares of NYMEX Holdings, Inc. common stock), and (iii) NYMEX Division Class A Memberships ("trading rights"). All bids and offers then currently on file with the membership department in connection with these categories were deemed null and void.

The Membership Department will begin accepting written bids and offers for (i) NYMEX Holdings, Inc. common stock (A1, A2 and A3); (ii) bundled seats (NYMEX Division Class A Membership "trading right" plus 90,000 shares of NYMEX Holdings, Inc. common stock), and (iii) NYMEX Division Class A Memberships ("trading rights"), beginning on Monday, October 23, 2006, at 9:00 AM.

Please be reminded that a letter to stockholders was recently mailed to you which describes the process by which you may elect to sell your NYMEX Holdings, Inc. common stock (A1, A2 and A3) in the contemplated NYMEX IPO. You are encouraged to read this letter carefully. This letter will be filed with the Securities and Exchange Commission and will be available on or prior to Monday, October 23, 2006 on the NYMEX website (www.nymex.com) under "Shareholder Relations/SEC Filings".

Please be advised, however, that our policy after November 1, 2006, with regard to accepting bids and offers for common stock, bundled seats and trading rights will be as follows:
  1. Commencing at 3:00 pm on Wednesday, November 1, 2006, the Company will permanently cease to accept, administer or post bids and offers for NYMEX Holdings, Inc. common stock.

  2. The Company will, however, continue accepting, administering and posting written bids and offers for bundled seats (NYMEX Division Class A Membership "trading right" plus 90,000 shares of NYMEX Holdings, Inc. common stock), and for NYMEX Division Class A Memberships ("trading rights").
A registration statement relating to the securities to be sold in the offering has been filed with the SEC but has not yet become effective. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This announcement shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of these securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state.
