###### Securities and Exchange Commission

          - [Release No. 34-52419; File No. SR-CBOE-2005-51] 

                    On June 30, 2005, the Chicago Board Options Exchange, Incorporated (“CBOE”), filed with the Securities and Exchange Commission (“Commission”) a proposed rule change pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1]                                          and Rule 19b-4 thereunder,[2]                                          to implement Amendment No. 15 to the Plan for the Purpose of Creating and Operating an Intermarket Option Linkage [3]                                          by                           ( print page 55193)                        amending CBOE Rules 6.80 and 6.84 to add a “trade and ship” exception to the definition of “Trade-Through” and add a “book and ship” exception to the provision relating to locked markets, respectively. On July 26, 2005, the CBOE filed Amendment No. 1 to the proposed rule change.[4]                                          The proposed rule change, as amended, was published for comment in the                     **Federal Register**                     on August 5, 2005.[5]                                          The Commission received no comments on the proposal. This order approves the proposed rule change, as amended.                

                    Under the proposed rule change, an order could be traded at a price that is one minimum quoting increment inferior to the national best bid or offer (“NBBO”) if a Linkage Order [6]                                          is sent contemporaneously to the market(s) disseminating the NBBO to satisfy all interest at the NBBO price. The proposed rule change also would provide that an order may be booked that would otherwise lock another market if a Linkage Order is sent contemporaneously to such other market to satisfy all interest at the lock price and only the remaining portion of the order is booked. The CBOE proposes that, under trade and ship, any execution received from the market disseminating the NBBO must (pursuant to agency obligations) be reassigned to the customer order that is underlying the Linkage Order that was sent to trade with the market disseminating the NBBO.                

                    After careful consideration, the Commission finds that the proposed rule change is consistent with the requirements of section 6 of the Act [7]                                          and the rules and regulations thereunder applicable to a national securities exchange.[8]                                          In particular, the Commission finds that the proposed rule change is consistent with section 6(b)(5) of the Act,[9]                                          which requires, among other things, 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, in general, to protect investors and the public interest. The Commission believes that the proposed rule change should help to implement the Linkage Plan by facilitating the ability of CBOE's members to execute their customer orders in a timely manner and potentially could decrease the incidence of Trade-Throughs and locked markets.                

*It is therefore ordered*                    , pursuant to Section 19(b)(2) of the Act,[10]                                          that the proposed rule change (SR-CBOE-2005-51) as amended, is approved.                

                        For the Commission, by the Division of Market Regulation, pursuant to delegated authority.[11] 

Jonathan G. Katz,

Secretary.
