          - [Release No. 34-55503; File No. SR-ISE-2007-20] 

      ( print page 14630)    
                     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 March 16, 2007, the International Securities Exchange, LLC (“ISE” or “Exchange”) 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 ISE. The Exchange filed the proposed rule change pursuant to Section 19(b)(3)(A) of the Act [3]                                          and Rule 19b-4(f)(6) thereunder,[4]                                          which renders the proposal 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 

                    The ISE is proposing to amend its rules governing Intermarket Sweep Orders (“ISOs”) to conform them to the rules of The NASDAQ Stock Market LLC (“Nasdaq”). The text of the proposed rule change is available at ISE, the Commission's Public Reference Room, and                     *http://www.ise.com*.                 

## 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 

                    The purpose of this filing is to amend ISE Rules governing ISOs to conform them to Nasdaq rules [5]                                          and to remove the requirement that ISOs be immediately executed or canceled. The proposed amendment clarifies the requirement that the Equity EAM entering an ISO to the ISE Stock Exchange must simultaneous route one or more additional limit orders, as necessary, to execute against the full displayed size of any Protected Bid or Offer in the case of a limit order to sell or buy with a price that is superior to the limit price of the limit order identified as an ISO (as defined in Rule 600(b) or Regulation NMS under the Act). These additional routed orders must be identified as ISOs. The Exchange notes that Equity EAMs wishing to display on ISE must route to protected quotes up to and including the price at which they wish to display in order to comply with the Locked and Crossed Market Rule.[6] 

#### 2. Statutory Basis 

                    The basis under the Act for this proposed rule change is found in Section 6(b)(5). Specifically, the Exchange believes that the proposed rule change is consistent with Section 6(b)(5) [7]                                          requirements that the rules of an exchange be designed to promote just and equitable principles of trade, serve 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, this filing will provide investors with more flexibility in entering orders and receiving executions of such orders.                 

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

The Exchange does not believe that the proposed rule change will 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 has not solicited, and does not intend to solicit, comments on this proposed rule change. The Exchange has not received any unsolicited written comments from members or other interested parties. 

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

                    Because the foregoing proposed rule change does not: (1) Significantly affect the protection of investors or the public interest; (2) impose any significant burden on competition; and (3) 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 filing date of the proposal.[8] 

                    A proposed rule change filed under Rule 19b-4(f)(6) normally may not become operative prior to 30 days after the date of filing.[9]                                          However, Rule 19b-4(f)(6)(iii) [10]                                          permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day pre-operative period, which would make the rule change operative immediately. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest, because the proposed rule change is substantially similar to rules previously approved by the Commission.[11]                                          For this reason, the Commission designates that the proposal become operative immediately.                 

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. 

## IV. Solicitation of Comments 

                    Interested persons are invited to submit written data, views, and arguments concerning the foregoing, including whether the proposed rule                           ( print page 14631)                        change is consistent with the Act.
