Self-Regulatory Organizations; Philadelphia Stock Exchange, Inc.; Notice of Filing of Proposed Rule Change and Amendment No. 1 Thereto Relating to the Modification of the Definition of Firm Customer Quote Size and the Removal of Certain Restrictions on Sending Secondary P/A Orders Under the Linkage Plan

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 April 26, 2005, the Philadelphia Stock Exchange, Inc. (“Phlx” 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 Phlx. On September 2, 2005, the Exchange submitted Amendment No. 1 to the proposed rule change. The Commission is publishing this notice to solicit comments on the proposed rule change, as amended, 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 to conform with a proposed amendment to the Plan for the Purpose of Creating and Operating an Intermarket Option Linkage (“Linkage Plan”). The Exchange is proposing to amend: (i) Exchange Rule 1083 by modifying the definition of Firm Customer Quote Size (“FCQS”), and (ii) Exchange Rule 1084 by deleting certain restrictions on sending secondary Principal Acting as Agent Orders (“P/A Orders”) pursuant to the Linkage Plan. The text of the proposed rule change, as amended, is available on Phlx's Web site at ( www.phlx.com ), at the Phlx'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 Exchange included statements concerning the purpose of, and basis for, the proposed rule change, as amended, 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 amend the definition of FCQS to reflect current practices of the respective Linkage Plan participants (“Participants”) relating to disseminated size that were not in existence at the time the Linkage Plan was originally adopted. At the time the Linkage Plan was originally adopted, options quote sizes generally were not disseminated through the Options Price Reporting Authority and most Participants employed automatic execution systems that guaranteed automatic executions of orders under a certain contract size (which was generally a static number). At that time, the FCQS was calculated based on the number of contracts the sending and receiving Participants guaranteed they would automatically execute. Now that all Participants disseminate dynamic quotes with size, the Exchange believes 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 Exchange Rule 1083(g) to define FCQS as the size of the disseminated quotation of the Participant receiving the P/A Order.

Another purpose of the proposed rule change is to eliminate a 15-second waiting period for sending a secondary P/A Order pursuant to Exchange Rule 1084(c)(2), which governs the manner in which a P/A Order larger than the FCQS can be broken into smaller P/A Orders. Currently, an initial P/A Order can be sent to the Participant whose disseminated price that is the National Best Bid or Offer (“NBBO”) for a size that is the FCQS. If the receiving Participant that is disseminating the NBBO continues to disseminate the same price after 15 seconds from the execution of the initial P/A Order, a secondary 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 wait 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. The Exchange also proposes to amend Exchange Rule 1084 to clarify that an automatic execution of a P/A Order is not required if the P/A Order is larger than the Firm Customer Quote Size, and that automatic execution will be provided for P/A orders at or below the FCQS, if automatic execution is available.

2. Statutory Basis

The Exchange believes that its proposed rule change, as amended, is consistent with Section 6(b) of the Act in general, and furthers the objectives of Section 6(b)(5) of the Act in particular, in that it is designed to perfect the mechanisms of a free and open market and a national market system, protect investors and the public interest and promote just and equitable principles of trade, by amending the definition of FCQS to reflect current practices of the Participants relating to disseminated size, and by eliminating the 15-second wait period for the sending of secondary P/A Orders to reflect current systems in place on the various Participants.

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

The Exchange does not believe that the proposed rule change, as amended, 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 Phlx consents, the Commission will:

A. By order approve such proposed rule change, as amended; or

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