The Twenty-Fourth Amendment proposes a non-substantive amendment to the Plan to reflect the name change of NYSE Chicago, Inc. to NYSE Texas, Inc.[5] A copy of the Plan, as proposed to be amended is attached as Exhibit A hereto. The Participants are filing the Twenty-Fourth Amendment for immediate effectiveness pursuant to Rule 608(b)(3)(iii) of Regulation NMS under the Exchange Act.[6]

II. Description of the Plan

The Participants submit this amendment to propose a non-substantive amendment to the LULD Plan to reflect the name change of NYSE Chicago, Inc. to NYSE Texas, Inc.

B. Governing or Constituent Documents

Because the amendment involves solely ministerial matters, the Participants are filing this proposal for immediate effectiveness pursuant to Rule 608(b)(3)(iii) of Regulation NMS under the Exchange Act.

D. Development and Implementation Phases
