          - [Release No. 34-52424; File No. SR-CBOE-2005-68] 

                    Pursuant to section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on August 29, 2005, the Chicago Board Options Exchange, Incorporated (“CBOE” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) the proposed rule change as described in Items I, II, and III below, which Items have been prepared by the CBOE. 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 proposes to amend its rules governing the operation of the intermarket option linkage (“Linkage”) to conform with a proposed amendment [3]                                          to the Plan for the Purpose of Creating and Operating an Intermarket Option Linkage (“Linkage Plan”).[4]                                          The Exchange is proposing: (i) To amend the definition of “Firm Customer Quote Size” (“FCQS”)[5]                                          to provide automatic executions for Linkage Principal Acting as Agent Orders (“P/A Orders”)[6]                                          up to the full size of the Exchange's disseminated quotation; and (ii) to eliminate a 15-second waiting period between the sending of P/A Orders.                 

                    The text of the proposed rule change is available on CBOE's Web site (                    *www.cboe.com*), at the CBOE's Office of the Secretary, 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 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 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 

                    The purpose of the proposed rule change is to modernize the definition of FCQS in CBOE rules related to the operation of the Linkage rules. At the time the Linkage commenced, options quote sizes were not disseminated through the Options Price Reporting Authority and most participants in the Linkage Plan employed automatic execution systems that guaranteed automatic fills on orders under a certain contract size (which was generally a static number). As such, the FCQS was                           ( print page 55194)                        calculated based on the number of contracts the sending and receiving Linkage Plan participants (“Participants”) guaranteed they would automatically execute. Now that all Participants disseminate dynamic quotes with size, the Participants believe that it is appropriate to calculate the FCQS based on the size of the disseminated quotation of the Participant receiving the P/A Order. Accordingly, the Exchange proposes to amend CBOE Rule 6.80 to effect this change.[7] 

                    The other purpose of the proposed rule change is to eliminate a 15-second wait period for sending a secondary P/A Order currently provided in Exchange Rule 6.81(b)(2). Exchange Rule 6.81(b)(2) governs the manner in which a P/A Order larger than the FCQS can be broken into smaller P/A Orders. Currently, Exchange Rule 6.81(b)(2) provides that an initial P/A Order can be sent to the Participant disseminating the National Best Bid or Offer for the FCQS, and if that Participant continues to disseminate the same price after 15 seconds from the execution of the initial P/A Order, a subsequent P/A Order can be sent for at least the lesser of (i) the size of the disseminated quote; (ii) 100 contracts; or (iii) the remainder of the customer order underlying the P/A Orders. The Exchange proposes to eliminate the 15-second waiting period because the dynamic quotes with size now employed by the Participants obviate the need for a manual quote refresh period for P/A Orders. This proposed rule change would conform the CBOE rules to the pending Amendment No. 16 to the Linkage Plan.[8] 

#### 2. Statutory Basis 

                    The Exchange believes that its proposal is consistent with section 6(b) of the Act [9]                                          in general, and furthers the objectives of section 6(b)(5) of the Act [10]                                          in particular, in that it is 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, in general, to protect investors and the public interest.                 

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

The 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 

Written comments were neither solicited nor received. 

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

                    Within 35 days of the date of publication of this notice in the                     **Federal Register**                     or within such longer period (i) as the Commission may designate up to 90 days of such date if it finds such longer period to be appropriate and publishes its reasons for so finding, or (ii) as to which the CBOE consents, the Commission will:                 

A. By order approve such proposed rule change; or 

B. Institute proceedings to determine whether the proposed rule change should be disapproved.
