Self-Regulatory Organizations; Chicago Board Options Exchange, Incorporated; Notice of Filing and Immediate Effectiveness of Proposed Rule Change Relating to the Appointment of CBSX DPMs

Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) and Rule 19b-4 thereunder, notice is hereby given that on November 27, 2006, the Chicago Board Options Exchange, Incorporated (“Exchange” or “CBOE”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I and II below, which Items have been substantially prepared by the Exchange. The Exchange has designated this proposal as non-controversial under Section 19(b)(3)(A)(iii) of the Act and Rule 19b-4(f)(6) thereunder, which renders the proposed rule change effective upon filing with the Commission. The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance of the Proposed Rule Change

CBOE proposes to adopt rules to appoint CBOE Stock Exchange DPMs. The text of the proposed rule change is available on the Exchange's Web site ( http://www.cboe.com ), at the Exchange's principal office, and at the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

In its filing with the Commission, the Exchange included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the most significant aspects of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

1. Purpose

In September 2006, the Commission approved Exchange Chapters 50-55 governing the trading of non-option securities on the Exchange. The Exchange, via a separate rule filing, will be proposing to further modify Chapters 50-55 in connection with the establishment of the CBOE Stock Exchange (“CBSX”). CBSX will be a facility of the Exchange and will serve as the Exchange's vehicle for trading non-option securities. CBSX is a separate legal entity (a Delaware Limited Liability Company) that is owned by the Exchange and several strategic partners. The Exchange separately has submitted a rule filing governing the allocation of securities to CBSX DPMs, and will shortly submit a rule filing proposing to establish CBSX as a facility of the Exchange.

The purpose of this filing is to adopt rules that will allow for the appointment of CBSX DPMs. Any such appointments would be contingent on Commission approval of rules governing CBSX DPM trading procedures and obligations. The Exchange hopes to launch CBSX on February 5, 2007. Establishing rules to allow for appointment of CBSX DPMs ahead of the anticipated launch of CBSX will allow the CBSX DPM firms to immediately market CBSX as a destination marketplace.

The Exchange expects CBSX will appoint a limited number of CBSX DPMs. In accordance with the proposed revisions to Rule 53.53, CBSX will select the firms that would be designated as CBSX DPMs. Factors to be considered in making such a selection are essentially identical to the factors set forth in the current rule applicable to STOC DPMs. Such factors may include, but are not limited to, any one or more of the following: (1) Adequacy of capital; (2) operational capacity; (3) trading experience and observance of generally accepted standards of conduct by the applicant; (4) number and experience of support personnel of the applicant; (5) regulatory history of adherence to Exchange rules by the applicant; (6) willingness and ability of the applicant to promote CBSX as a marketplace; (7) performance evaluations conducted pursuant to Exchange/CBSX rules; and (8) in the event that one or more shareholders, directors, officers, partners, managers, members, or other principals of an applicant is or has previously been a shareholder, director, officer, partner, manager, member, or other principal in another CBSX DPM, adherence by such CBSX DPM to the requirements set forth in CBSX rules regarding CBSX DPM responsibilities and obligations during the time period in which such person(s) held such position(s) with the CBSX DPM.

2. Statutory Basis

CBOE believes the proposed rule change is consistent with the Act and the rules and regulations under the Act applicable to a national securities exchange and, in particular, the requirements of Section 6(b) of the Act. Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) requirements that the rules of an exchange be designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and to protect investors and the public interest.

B. Self-Regulatory Organization's Statement on Burden on Competition

CBOE does not believe that the proposed rule change would impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.

C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants or Others

The Exchange neither solicited nor received comments on the proposal.

III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

The Exchange has filed the proposed rule change pursuant to Section 19(b)(3)(A) of the Act and subparagraph (f)(6) of Rule 19b-4 thereunder. Because the foregoing proposed rule change (i) does not significantly affect the protection of investors or the public interest; (ii) does not impose any significant burden on competition; and (iii) does not become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate, if consistent with the protection of investors and the public interest, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6)(iii) thereunder.

A proposed rule change filed under Rule 19b-4(f)(6) normally does not become operative for 30 days after the date of filing. However, Rule 19b-4(f)(6)(iii) permits the Commission to waive the operative delay if such action is consistent with the protection of investors and the public interest. The Exchange has asked the Commission to waive the operative delay to permit the proposed rule change to become effective prior to the 30th day after filing.

The Commission has determined to waive the 30-day delay and allow the proposed rule change to become operative immediately. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest. The proposed rule is substantially similar to the previous version of the rule approved for the Exchange's STOC system.

At any time within 60 days of the filing of the proposed rule change, the Commission may summarily abrogate such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act.
