###### Securities and Exchange Commission

          - [Release No. 34-62204; File No. SR-CBOE-2010-049]

                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on May 25, 2010, the Chicago Board Options Exchange, Incorporated (“Exchange” or “CBOE”) filed with the Securities and Exchange Commission (the “Commission”) the proposed rule change as described in Items I, II, and III 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                           ( print page 32524)                        the Act [3]                                          and Rule 19b-4(f)(6) thereunder.[4]                                          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

                    The Exchange is proposing to amend its rules to clarify the applicability of various order types on the Exchange. The text of the proposed rule change is available on the Exchange's Web site (                    *http://www.cboe.org/​Legal*), 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 self-regulatory organization 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 modify Rule 6.53,                     *Certain Types of Orders Defined,*                     to clarify that one or more of the various order types may be made available on a class-by-class basis.[5]                                          The proposed text would also clarify that certain order types may not be made available for all Exchange systems. The classes and/or systems for which the order types shall be available will be as provided in the Rules, as the context may indicate, or as otherwise specified via Regulatory Circular generally at least one day in advance.                

                    The proposed rule change provides additional clarity and consistency in our rules, which already provide in various places that the Exchange may designate the eligible order types on a class-by-class basis for various systems/processes. For example, the proposed change is consistent with Rules 6.13A,                     *Simple Auction Liaison (SAL),*                     6.14A,                     *Hybrid Agency Liaison 2 (HAL2),*                     and 6.53C(d),                     *Process for Complex Order RFR Auction*                     (“COA”), which provide that the Exchange, among other things, shall designate the eligible order types and classes in which SAL, HAL2 or COA will be activated. As another example, Rule 6.53(o),                     *Attributable Order,*                     provides that attributable orders may not be available for all Exchange systems and the Exchange will issue a Regulatory Circular specifying the systems for which the attributable order type shall be available.                

#### 2. Statutory Basis

                    The basis under the Act for this proposed rule change is the requirement under Section 6(b)(5) [6]                                          that an exchange have rules that are designed to promote just and equitable principles of trade, and to remove impediments to and perfect the mechanism for a free and open market and a national market system, and, in general, to protect investors and the public interest. In particular, the Exchange believes the proposed change would provide more clarity on the applicability of eligible order types in a manner that is consistent with other provisions in the existing CBOE rules.                

### 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 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 self-regulatory organization 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,[7]                                          the proposed rule change has become effective pursuant to Section 19(b)(3)(A) of the Act [8]                                          and Rule 19b-4(f)(6) thereunder.[9]                                          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.
