Self-Regulatory Organizations; Chicago Board Options Exchange, Incorporated; Notice of Filing and Immediate Effectiveness of Proposed Rule Change To Extend a Pilot Program Relating to Electronic DPMs and Affiliated Market-Makers

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 December 23, 2005, 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 prepared by the Exchange. The Exchange filed the proposal as a “non-controversial” proposed rule change pursuant to Section 19(b)(3)(A)(iii) of the Act and Rule 19b-4(f)(6) thereunder. 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 extend the pilot allowing Electronic DPMs (“e-DPMS”) to have up to one affiliated Market-Maker trade in classes assigned to the e-DPM. The text of the proposed rule change is available on the Exchange's Web site ( http://www.cboe.com ), at the Exchange's Office of the Secretary, and at the Commission.

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 CBOE 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 those 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 parts of such statements.

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

1. Purpose

The Exchange proposes to amend CBOE Rule 8.93(vii) to extend the pilot program allowing an e-DPM the option to have up to one separate affiliated Market-Maker physically present in the trading crowds where it operates as an e-DPM (such Market-Makers would be required to trade on a separate membership). The pilot would be extended from January 12, 2006 until September 14, 2006.

In July of 2004, the SEC approved File No. SR-CBOE-2004-24, which established the e-DPM program, including the pilot program. The pilot allows e-DPM firms to maintain a physical presence in the trading crowd through an affiliated Market-Maker, who would also be able to electronically stream a quote. The pilot, however, limits the number of separate affiliates per trading crowd to one.

CBOE will be sending the Commission, under separate cover, data relating to: (1) The size of the orders that e-DPM's and affiliated Market-Makers both trade with electronically; (2) the price and size of the e-DPM's and the affiliated Market-Maker's respective quotes; (3) the price and size of quotes of other participants in the classes where an e-DPM and an affiliate are quoting; and (4) a breakdown of how orders are allocated to the e-DPM, the affiliated Market-Maker, and any other participants.

The date chosen to extend the pilot program corresponds with the ending date of a matching pilot program for Remote Market-Makers (RMMs) found in CBOE Rule 8.4(c)(i). Thus, the date chosen would allow the Commission to evaluate both pilot programs simultaneously.

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, 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 will impose any burden on competition 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

Because the foregoing proposed rule does not (i) significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) 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, provided that the Exchange has given the Commission written notice of its intent to file the proposed rule change at least five business days prior to the date of filing of the proposed rule change or such shorter time as designated by the Commission, the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) thereunder. At any time within 60 days of the filing of such 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.

Under Rule 19b-4(f)(6)(iii) of the Act, the proposal does not become operative for 30 days after the date of its filing, or such shorter time as the Commission may designate if consistent with the protection of investors and the public interest. The Exchange has requested that the Commission accelerate the 30-day operative date and waive the five day pre-filing requirement. The Commission, consistent with the protection of investors and the public interest, has determined to accelerate the 30-day operative date and waive the five day pre-filing requirement, so that the e-DPM pilot program may continue without interruption.
