1. Equity

The Exchange is authorized to issue (i) 1,000,000 shares of common stock, 50,500 shares of which are designated Class A Common Stock and 949,500 shares of which are designated Class B Common Stock (collectively, the Common Stock), and (ii) 100,000 shares of preferred stock, all with a par value of $.01 per share. As described below, one share of Series A Preferred Stock was issued.

Shareholder and Independent Governors of the Exchange are elected by the holders of the Common Stock. Member and Designated Independent Governors are chosen, and their removal may be directed by the members (permit holders) of the Exchange. All voting rights of a member are exercised through the member organization with which the member is primarily affiliated. The Member and Designated Independent Governors who are chosen by the members are formally elected at the annual meeting of stockholders by the Phlx Member Voting Trust (the Trust), a Delaware statutory trust whose trustee is an independent institution that is required to vote in accordance with the vote of the Exchange’s members. One share of Series A Preferred Stock of the Exchange was issued to the Trust, the sole purpose of which is to allow the Trust to vote for the election or removal of Member and Designated Independent Governors as directed by a member vote. Except for the election and removal of Member and Designated Independent Governors, and subject to the rights of any class or series of preferred stock if and when issued, the Common Stock retains all voting rights of the stockholders of the Exchange.

The holders of the Common Stock will have all dividend and other distribution rights of stockholders in the Exchange, subject to the rights of any class or series of preferred stock, if and when issued. The Series A Preferred Stock does not have any dividend rights. The Exchange’s by-laws prohibit the payment of dividends from revenues received by the Exchange from regulatory fines, fees or penalties.

On January 20, 2007, the third anniversary of the demutualization of the Exchange, all 46,900 shares of Class A Common Stock converted to Class B Common Stock such that all 441,504 shares of the Exchange are, as of that date, Class B shares. Upon conversion to Class B, the eligibility of holders of Class A shares for a contingent dividend terminated. The former holders of the Class A shares otherwise continue to have the same rights and privileges, including voting, as the Class B holders.
