          - [Release No. 34-55613; File No. SR-CHX-2007-11] 

                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on March 22, 2007, the Chicago Stock Exchange, Inc. (“CHX” 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 substantially prepared by the CHX. On April 10, 2007, the CHX filed 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 CHX proposes to amend its Schedule of Participant Fees and Credits (the “Fee Schedule”) to remove provisions that are no longer in effect due to the roll-out of the Exchange's new trading model. The text of this proposed rule change is available at the CHX, on the Exchange's Web site at                     *http://www.chx.com/​rules/​proposed_​rules.htm,*                     and in 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 CHX 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 CHX 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 

                    On January 26, 2007, the CHX completed the transition to its new trading model.[3]                                          The Exchange now proposes to amend its Fee Schedule to delete several provisions that are no longer in effect as a result of that transition. The provisions of the Fee Schedule that would be deleted through this filing include: (1) Section E(8) (Transaction and Order Processing Fees Associated with Securities Not Yet Traded in the Matching System); (2) Parts of Section F(2) (Institutional Broker Credits); (3) Section F(4) (Two-Sided Quote Providers); (4) Section L (Space Charges); and (5) Section M (Equipment, Information Services and Technology Charges). Each of these provisions currently contains an introductory note confirming that it is only in effect until the transition to the new trading model or contains an effective date that has been exceeded.[4]                                          Because of the transition to the new trading model, these fees are no longer in effect for the Exchange's participants.[5] 
      ( print page 19223)    

#### 2. Statutory Basis 

###                     The proposed rule change is consistent with Section 6(b)(4) of the Act [6]                                          in that it provides for the equitable allocation of reasonable dues, fees and other charges among its members.                 

### 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. 

### C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants or Others 

No written comments were either solicited or received. 

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

                    Because the foregoing proposed rule change establishes or changes a member due, fee or other charge imposed by the Exchange, it has become effective pursuant to Section 19(b)(3)(A) of the Act [7]                                          and subparagraph (f)(2) of Rule 19b-4 thereunder.[8]                                          At any time within 60 days of the filing of such 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.[9]

5.                             For example, an additional network/connectivity fee credit was available to institutional brokers until the completion of the new trading model rollout.                         *See*                         Section F(2) of the Fee Schedule. Similarly, with the transition to the new trading model, the CHX no longer operates a physical trading floor; as a result, the space and equipment charges are no longer charged to participants pursuant to the Fee Schedule, but are instead part of separate agreements between the Exchange and any firms that sublease space on the Exchange's former trading floor.                         *See*                         Sections L and M of the Fee Schedule.
