In the event a Holder of Income PRIDES so elects, such Holder may Transfer Treasury Securities to the Collateral Agent for the benefit of the Company in exchange for the release by the Collateral Agent on behalf of the Company of Preferred Securities to the Purchase Contract Agent on behalf of such Holder. Treasury Securities shall be Transferred to the Collateral Account maintained by the Collateral Agent at the Securities Intermediary by book-entry transfer to the Collateral Account in accordance with the TRADES Regulations and by the notation by the Securities Intermediary on its books that a Security Entitlement with respect to such Treasury Securities has been credited to the Collateral Account. For purposes of perfecting the Pledge under applicable law, including, to the extent applicable, the TRADES Regulations, the Uniform Commercial Code as adopted and in effect in any applicable jurisdiction or Revised Article 8 as made applicable by the TRADES Regulations, the Collateral Agent shall be the agent of the Company as provided herein. The pledge provided in this Section 2.1 is herein referred to as the "Pledge" and the Preferred 8 13 Securities or Treasury Securities subject to the Pledge, excluding any Preferred Securities or Treasury Securities released from the Pledge as provided in Section 4 hereof, are hereinafter referred to as "Pledged Preferred Securities" or the "Pledged Treasury Securities," respectively. Subject to the Pledge and the provisions of Section 2.2 hereof, the Holders from time to time shall have full beneficial ownership of the Collateral. Whenever directed by the Collateral Agent acting on behalf of the Company, the Securities Intermediary shall have the right to reregister the Preferred Securities or any other securities held in physical form in its name. Except as may be required in order to release Preferred Securities in connection with a Holders election to convert its investment from an Income Pride to a Growth Pride, or except as otherwise required to release securities as specified herein, the Collateral Agent shall not relinquish physical possession of any certificate evidencing a Preferred Security prior to the termination of this Agreement. If it becomes necessary for the Collateral Agent to relinquish physical possession of a certificate in order to release a portion of the Preferred Securities evidenced thereby from the Pledge, the Collateral Agent shall use its best efforts to obtain physical possession of a replacement certificate evidencing any Preferred Securities remaining subject to the Pledge hereunder registered to it or indorsed in blank within fifteen days of the date it relinquished possession. The Collateral Agent shall promptly notify the Company of its failure to obtain possession of any such replacement certificate as required hereby. Section 2.2. Control and Perfection. In connection with the Pledge granted in Section 2.1, and subject to the other provisions of this Agreement, the Holders from time to time acting through the Purchase Contract Agent, as their attorney-in-fact, hereby authorize and direct the Securities Intermediary (without the necessity of obtaining the further consent of the Purchase Contract Agent or any of the Holders), to comply with and follow any instructions and entitlement orders (as defined in Section 8-102(a)(8) of Revised Article 8) that the Collateral Agent on behalf of the Company may give in writing with respect to the Collateral Account, the Collateral credited thereto and any security entitlements with respect to any thereof. Such instructions and entitlement orders 9 14 may, without limitation, direct the Securities Intermediary to transfer, redeem, sell, liquidate, assign, deliver or otherwise dispose of the Preferred Securities, the Treasury Securities and any security entitlements with respect thereto and to pay and deliver any income, proceeds or other funds derived therefrom to the Company. The Holders from time to time acting through the Purchase Contract Agent hereby further authorize and direct the Collateral Agent, as agent of the Company, to itself issue instructions and entitlement orders, and to otherwise take action, with respect to the Collateral Account, the Collateral credited thereto and any security entitlements with respect to any thereof, pursuant to the terms and provisions hereof, all without the necessity of obtaining the further consent of the Purchase Contract Agent or any of the Holders. In addition, to further protect and perfect the Pledge, the Securities Intermediary agrees that it will, until New York adopts Revised Article 8, at all times mark its books with respect to the Collateral Account to show that all securities credited thereto are subject to the Pledge in favor of the Collateral Agent for the benefit of the Company. The Collateral Agent shall be the Agent of the Company and shall act as directed in writing by the Company. Without limiting the generality of the foregoing, the Collateral Agent shall issue entitlement orders to the Securities Intermediary when and as directed by the Company. Section 3. Distributions on Pledged Collateral. So long as the Purchase Contract Agent is the registered owner of the Pledged Preferred Securities it shall receive all payments thereon.
