Dear CBOT Members:

On December 22, CBOT Holdings and the Board of Trade of the City of Chicago, Inc. (collectively, CBOT) filed a motion in their lawsuit against Chicago Board Options Exchange, Inc. (CBOE) and its directors currently pending in the Delaware Court of Chancery. The motion seeks leave to add claims arising from the CBOE’s recent actions.

The complaint already on file in the case seeks a declaration that exerciser members of the CBOE and those who hold the Exercise Right are entitled to the same treatment as other CBOE members in the CBOE’s announced plan to demutualize. The complaint which the CBOT now seeks leave to file includes claims arising from certain of the CBOE’s recent actions. Recently:

 

    The CBOE’s board created a Special Committee of Independent Directors, purportedly for the purpose of determining how CBOE membership interests, including memberships held by those who purchased their membership interest and those who acquired their membership interest through the Exercise Right, would be treated in the CBOE’s planned demutualization. That Special Committee solicited written and oral testimony, and held an “Open Forum” on November 2, 2006 for the purpose of hearing such oral testimony;

 

    The CBOE’s board then, unilaterally and without prior notice to the CBOT or the Exercise Right holders, “decreed” that the Exercise Right would terminate as a result of the proposed merger between CBOT Holdings and Chicago Mercantile Exchange Holdings, Inc. (CME Holdings);

 

    The CBOE then submitted to the U.S. Securities and Exchange Commission (SEC) a proposed rule change that purported to implement the decree by the CBOE’s board that the Exercise Right would terminate as a result of the proposed merger between CBOT Holdings and CME Holdings; and

 

    The CBOE’s board also announced that the Special Committee suspended its work because the Special Committee determined it was no longer necessary to ascribe a value

to memberships acquired through the Exercise Right as a result of the CBOE’s board’s decree that the merger would terminate the Exercise Right.

The relief sought by the CBOT in the proposed complaint – in addition to the relief sought in the previous complaint – includes an injunction barring the CBOE from interfering with the Exercise Right upon the completion of the merger between CBOT Holdings and CME Holdings, and a declaration that the CBOE and its board breached the CBOE’s charter, certain of the CBOT-CBOE agreements, and their fiduciary duties to the Exercise Right holders when it announced its plan to terminate the Exercise Right.

The Delaware court has not yet ruled on the CBOT’s motion.

On the same day as its filing in the Delaware, attorneys for the CBOT, as well as attorneys for the putative class of Exerciser Right holders, sent separate letters to the SEC regarding the CBOE’s proposed rule filing. Those submissions to the SEC requested that the SEC take no action on the CBOE’s submission because of the pending action before the Delaware court. To the best of our knowledge, the SEC has taken no action on either the CBOE’s proposed rule filing or the CBOT and class submissions.

All of these actions are consistent with our commitment to vigorously defend the rights of CBOT members to become exerciser members of the CBOE.

 

   Very truly yours,
