The Shares reported in this Schedule 13D as beneficially owned by the Oak Street Reporting Persons were acquired with funds of approximately $22,246,220 (including brokerage commissions).

The Reporting Persons acquired the Shares in the ordinary course of business for investment purposes based on their belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. The Reporting Persons continually review their respective investment in the Issuer and other entities in which they have invested. As part of that review, the Reporting Persons have determined that they may seek a more active role in influencing the Issuer’s affairs in order to protect and maximize the value of their investment. To that end, they may engage in discussions with the Issuer’s management and the Board of Directors of the Issuer regarding alternatives means to maximize stockholder value, may engage in dialogues with other stockholders and may seek representation on the

Board of Directors of the Issuer. The Reporting Persons held several discussions before December 8, 2010 to discuss the transactions contemplated by the matters described in this Item 4, but no agreement was reached among the Oak Street Reporting Persons and the Kovitz Reporting Persons as a result of such discussions, and no group was formed under Section 13(d)(3) under the Securities Exchange Act of 1934 (the “Exchange Act”) and Rule 13d-5(b)(1) promulgated thereunder, until December 8, 2010.

Other than as set forth in this Item 4, the Reporting Persons do not have any current plans, proposals or negotiations that relate to or would result in any of the matters referred to in paragraphs (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons intend to review their respective investment in the Issuer on a continuing basis, and to the extent permitted by law, may seek to engage in discussions with other stockholders and/or with management and the Board of Directors of the Issuer concerning the business, operations or future plans of the Issuer. Depending on various factors including, without limitation, the Issuer’s financial position, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may, in the future take such actions with respect to their respective investment in the Issuer as they deem appropriate including, without limitation, purchasing additional Shares, selling of Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares, taking any other action with respect to the Issuer or any of its securities in any manner permitted by law or changing their intention with respect to any and all matters referred to in paragraphs (a) through (j) of Item 4.
