Self-Regulatory Organizations; Pacific Exchange, Inc.; Notice of Filing of Proposed Rule Change Relating to Exposure of Orders in the PCX Plus Crossing Mechanism

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 December 22, 2005, the Pacific Exchange, Inc. (“PCX” 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 PCX. 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 PCX is proposing to decrease the exposure period in its Crossing Mechanism from ten seconds to three seconds. The text of the proposed rule change is available on the PCX's Web site ( http://www.pacificex.com ), at the PCX'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 PCX 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 PCX 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

PCX rules provide that a PCX Broker may not facilitate orders or cross two orders, using the Crossing Mechanism of the PCX Plus System (“PCX Plus” or “System”), unless it enters into the System the terms of each order that is to be included as part of a Cross Order, pursuant to PCX Rule 6.76(c)(2)(A). Both facilitation crosses and non-facilitation crosses are executed in the same manner in PCX Plus. Upon entry into PCX Plus, the System will evaluate the terms of the Cross Order and, after accepting the Cross Order, will execute the cross in accordance with PCX Rule 6.76(c)(2)(B). Among other conditions, Rule 6.76(c)(2)(B) requires a ten-second exposure period in which OTP Holders and OTP Firms may enter orders to trade against the side of the Cross Order that has been designated as the Exposed Order. It is this portion of the Crossing Mechanism rule that the PCX proposes to change. The PCX believes that establishing a three-second exposure period within the PCX Plus Crossing Mechanism would be consistent with the three-second exposure period that was recently approved for use at the International Securities Exchange (“ISE”) in SR-ISE-2004-04.

The Exchange proposes to shorten the duration of the exposure period contained in the rules governing the Crossing Mechanism, as set forth in PCX Rule 6.76(c)(2)(B)(i)(a) and PCX Rule 6.76(c)(2)(B)(ii)(b), from ten seconds to three seconds. This shortened exposure period is fully consistent with the electronic nature of the System. All market participants on the PCX utilize electronic trading systems that monitor all updates to the PCX market, including changes resulting from orders being entered into the Crossing Mechanism, and can automatically respond based upon pre-set parameters. In this all-electronic environment, it is not necessary to provide an exposure time sufficiently long to permit a person to manually respond to an updated market in order to provide the opportunity for crowd interaction. Thus, an exposure period of three seconds will permit exposure of orders on the PCX in a manner consistent with the Exchange's electronic market.

By reducing the exposure period from ten seconds to three seconds the PCX believes that OTP Holders and OTP Firms will be able to provide liquidity to their customers' orders on a timelier basis, thus providing investors with more speedy executions. Timely and accurate executions are consistent with the principles under which PCX Plus was developed. Reducing the exposure period to three seconds will also allow the PCX to remain competitive with the ISE, which has already received approval to reduce its exposure period to three seconds.

2. Statutory Basis

The basis under the Act for this proposed rule change is the requirement under Section 6(b)(5) that an exchange have rules that are designed to foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, 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. In particular, the proposed rule change will provide investors with more timely execution of their options orders, while ensuring that there is an adequate exposure of all crossing orders in the PCX marketplace.

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

The proposed rule change does not 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

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 PCX consents, the Commission will:

(A) By order approve such proposed rule change, or
