Pursuant to Section 11A of the Securities Exchange Act of 1934 (“Act”) ^[1] and Rule 608 of Regulation NMS thereunder,^[2] notice is hereby given that on September 14, 2007, September 19, 2007, August 29, 2007, August 29, 2007, August 30, 2007, and September 26, 2007, American Stock Exchange, LLC (“Amex”), Boston Stock Exchange, Inc. (“BSE”), Chicago Board Options Exchange, Incorporated (“CBOE”), International Securities Exchange, LLC (“ISE”), NYSE Arca, Inc. (“NYSE Arca”), and Philadelphia Stock Exchange, Inc. (“Phlx”) (collectively, the “Participants”), respectively, submitted to the Securities and Exchange Commission (“Commission”) Amendment No. 24 to the Plan for the Purpose of Creating and Operating an Intermarket Option Linkage (“Linkage ( printed page 58134) Plan”).^[3] The amendment proposes to eliminate the “Class Gate” restriction on Principal Order access through the Linkage. The Commission is publishing this notice to solicit comments from interested persons on the proposed Joint Amendment to the Linkage Plan.

I. Description of the Proposed Amendment

The Participants are proposing to modify Section 7(a)(ii)(C) of the Linkage Plan so as to eliminate the “Class Gate” restriction on Principal Order access through the Linkage. Currently, Section 7(a)(ii)(C) of the Linkage Plan provides that, once a Participant automatically executes a Principal Order in a series of an Eligible Option Class, it may reject any other Principal Orders sent in the same Eligible Option Class by the same Participant for 15 seconds after the initial execution unless there is a price change in the receiving Participant's disseminated offer (bid) in the series in which there was the initial execution and such price continues to be the NBBO. After the 15 second period, and until the sooner of one minute after the initial execution or a change in its disseminated offer (bid), the Section provides that the Participant that provided the initial execution is not obligated to execute any Principal Orders received from the same Participant in the same Eligible Option Class in its automatic execution system.

The Participants represent that a change to the “Class Gate” provision is appropriate because, at the time of the creation of the Linkage, various markets had restrictions on non-customer access to the automatic execution systems. Since then, all of the exchanges have removed those restrictions and allow access for orders on behalf of non-member market makers to their trading platforms, thus eliminating the need for the “Class Gate.”

II. Implementation of the Plan Amendment

The proposed amendment to the Linkage Plan will be effective upon approval by the Commission pursuant to Rule 608 of Regulation NMS under the Act.^[4]
