If, on the Settlement Date, the Settlement Amount is greater than the Reference Amount, MLI will pay the Companies an amount in cash or Paired Shares (valued at the Closing Price on the Settlement Date) equal to the difference. ii. If the number of Paired Shares sold by MLI pursuant to Section 3.1 is greater than the number of Settlement Shares, the Companies shall deliver to MLI, on the Settlement Date, a number of Paired Shares equal to the difference. If the number of Paired Shares sold by MLI pursuant to Section 3.1 is less than the number of Settlement Shares, MLI shall deliver to the Companies, on the Settlement Date, a number of Paired Shares equal to the difference. iii.

In the event that on the date of any cash payment contemplated by Section 3.3(a) or 3.3(b) no such Interim Settlement Shares are held in the Collateral Account or after giving effect to the application of any cash payment no such Interim Settlement Shares will be held in the Collateral Account, the Merrill Lynch Parties shall deliver, or cause to be delivered, within five (5) Business Days to the Companies, in addition to any Interim Settlement Shares required to be delivered, that number of Paired Shares then held by the Merrill Lynch Parties pursuant to the Purchase Agreement or this Agreement in excess of that number of Paired Shares determined by dividing the Reference Amount (after deducting any such cash payment not applied in respect of Interim Settlement Shares) by the Closing Price on the date of such payment or transfer. Any such delivery of excess Paired Shares other than Interim Settlement Shares shall reduce the number of Adjustment Shares by the number of Paired Shares so delivered. 4. Settlement by the Merrill Lynch Parties. a. Settlement Sales. i. After the Standstill (as defined in the Settlement Agreement) ends, MLI shall have the right to sell in any of the manners set forth in Section 3.1 or 4.1(b) hereof (the "Settlement") 100% of the Adjustment Shares and in connection therewith to sell a number of Paired Shares equal to the number of Paired Shares purchased by MLI pursuant to the Purchase Agreement (the "Original Shares") and any and all Interim Settlement Shares.

At the option of MLI, subject to the ownership limitation provisions of Section 6.2 hereof, (i) all right, title and interest to Interim Settlement Shares having a value (based on the Closing Price on such date) equal to (x) the Reference Amount on such date less (y) an amount equal to the Adjustment Shares multiplied by the Closing Price on such date shall be transferred to MLI and (ii) such Interim Settlement Shares shall be transferred to an account at MLPF&S in the name of and for the exclusive benefit of MLI (the "MLI Account"). The number of Paired Shares in the MLI Account in excess of the number of Paired Shares equal to the Adjustment Shares (the "Additional Shares") shall continue to be treated as Interim Settlement Shares for purposes of this Agreement. iv. Upon reduction of the Reference Amount in the Secured Adjustment Agreement to zero (-0-) dollars through the payment of cash by the Companies to MLI: (i) a Reset Date shall occur, (ii) the lesser of (x) 2,645,000 Paired Shares or (y) such number of Paired Shares as remains in the Collateral Account shall be transferred to the MLI Account, (iii) the number of Adjustment Shares shall be increased by such number of Paired Shares determined pursuant to clause (ii) above, and (iv) the Reference Price shall be recalculated by multiplying the Reference Price determined 10 as of such Reset Date by the quotient of (x) the number of Adjustment Shares immediately prior to such transfer pursuant to clause (ii) above divided by (y) the number of Adjustment Shares calculated pursuant to clause (iii) above. v. The transfer of Additional Shares pursuant to Section 4.1(c) or the transfer of Paired Shares pursuant to Section 4.1(d) shall constitute the purchase of a securities entitlement from the Companies for value by MLI and the transfer of all right, title and interest in and to the Additional Shares to MLI, and after such transfer MLI shall be the owner of such Additional Shares for all purposes. b.
