Item 1.01.    Entry into a Material Definitive Agreement
On February 10, 2006, NYMEX Holdings, Inc. (the "Company") and General Atlantic Partners 82, L.P., GapStar, LLC, GAP Coinvestments III, LLC, Gap Coinvestments IV, LLC and GAPCO GmbH & Co. KG (collectively, "General Atlantic") entered into an amendment (the "Amendment") to the Stock Purchase Agreement dated November 14, 2005 (as amended "the Purchase Agreement") which provides for the issuance and sale of 8,160,000 shares of the Company's newly-created Series A Cumulative Redeemable Convertible Preferred Stock, par value $0.01 per share (the "Series A Preferred Stock").  The gross proceeds from the issuance and sale will be distributed to the Company's existing stockholders in the form of an extraordinary cash distribution.  General Atlantic will not participate in the distribution.  The issuance and sale of the shares of Series A Preferred Stock and the other actions contemplated by the Purchase Agreement are referred to herein as the "Transaction."  The Amendment:
-        increased the aggregate purchase price from $135 million to $160 million;
-        provides for an additional payment of $10 million payable, on the closing date of the initial public offering, if the special meeting of stockholders to approve the Transaction is held on or prior to March 15, 2006, an initial public offering that values the Company's equity at $2 billion or greater occurs in 2006, and the next annual meeting of stockholders to elect the fifteen (15) member board occurs on or prior to May 1, 2006;
-        refined the post-Transaction authorized capital of the Company;
-        eliminated General Atlantic's right to share in pre-closing dividends up to the $33,600,000 which had already been declared;
-        provides that Mr. William E. Ford will join the board and fill the currently existing one (1) vacancy at the closing of the Transaction (the "Closing"), and that the number of directors of the Company shall be reduced from twenty-five (25) to fifteen (15) directors at the next annual meeting to be held no later than May 1, 2006; and
-        increased the amount of General Atlantic's reasonable fees, disbursements and other charges of counsel reasonably incurred in connection with the Transaction up to an aggregate amount of $500,000, from $250,000.  The Company otherwise has no "break-up fee," expense reimbursement or other financial obligation in the event the Transaction does not occur.
The Closing is expected to occur shortly after the March 13, 2006 special meeting of stockholders.  The conditions to the Closing include: (i) the approval of the Company's stockholders, (ii) the approval of the Commodity Futures Trading Commission, (iii) the execution and delivery of an investor rights agreement and a registration rights agreement to be entered into by the Company and General Atlantic, (iv) the adoption of certain modifications to the existing certificates of incorporation and bylaws of the Company and New York Mercantile Exchange, Inc., a wholly-owned subsidiary of the Company, including modifications providing for the "de-stapling" of the Company's common stock and the Exchange's membership rights that represent trading privileges on the Exchange, and (v) other customary closing conditions.
The foregoing is a summary of the terms of the Amendment and is qualified in its entirety by reference to the Amendment, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 1.01.
