Ownership Limitations. (a) To the fullest extent permitted by law, from and after the Effective Date and prior to the Restriction Release Date: (A) no Person shall be permitted to make an Acquisition, whether in a single transaction or series of related transactions, and any such purported Acquisition will be void ab initio, to the extent that after giving effect to such purported Acquisition (i) the purported acquiror or any other Person by reason of the purported acquiror’s Acquisition would become a Substantial Holder, or (ii) the Percentage Stock Ownership of a Person that, prior to giving effect to the purported Acquisition, is a Substantial Holder would be increased; and (B) no Substantial Holder shall Dispose of any Corporation Securities without consent of the Board, as provided in Section 2(b) of Article VI, and any such purported Disposition will be void ab initio. The prior sentence is not intended to prevent the Corporation Securities from being DTC-eligible and shall not preclude the settlement of any transaction in the Corporation Securities entered into through the facilities of a national securities exchange but such transaction, if prohibited by the prior sentence, shall nonetheless be a Prohibited Transfer. (b) The restrictions set forth in Section 2(a) of Article VI shall not apply to a proposed Transfer, and such Transfer shall be permitted notwithstanding anything to the contrary in Section 2(a), if the transferor or the transferee, upon providing at least fifteen (15) days prior written notice of such proposed Transfer to the Board, obtains the written approval or consent to the proposed Transfer from the Board. The Board will consider whether the proposed Transfer, when considered alone or with other proposed or planned Transfers, will impair the Corporation’s Tax Benefits and may, within its discretion, determine whether to permit the proposed Transfer, or not to permit the proposed Transfer, in order to protect the Corporation’s Tax Benefits. If a Substantial Holder proposes to Dispose of stock in a transaction that would otherwise be limited by Section 2(a)(B) of Article VI, the Board shall approve such proposed Disposition, unless the Board determines in good faith that the proposed Disposition, whether considered alone or with other transactions (including, without limitation, past transactions or contemplated transactions), would create a material risk that the Corporation’s Tax Benefits may be jeopardized. The Board shall endeavor to inform the requesting party of its determination within ten (10) days after receiving such written notice; provided, however, that the failure of the Board to respond during such ten (10) day period shall not be deemed

Treatment of Excess Securities. (a) No employee or agent of the Corporation shall record any Prohibited Transfer, and the purported transferee (the “Purported Transferee”) of a Prohibited Transfer shall not be recognized as a shareholder of the Corporation for any purpose whatsoever in respect of the Corporation Securities which are the subject of the Prohibited Transfer (the “Excess Securities”). Until the Excess Securities are acquired by another Person in a Transfer that is not a Prohibited Transfer, the Purported Transferee shall not be entitled with respect to such Excess Securities to any rights of shareholders of the Corporation, including, without limitation, the right to vote such Excess Securities and to receive dividends or distributions, whether liquidating or otherwise, in respect thereof. Once the Excess Securities have been acquired in a Transfer that is in accordance with Section 3 of Article VI and is not a Prohibited Transfer, such Corporation Securities shall cease to be Excess Securities. (b) If the Board determines that a Prohibited Transfer has occurred, such Prohibited Transfer and, if applicable, the recording of such Prohibited Transfer, shall, to the fullest extent permitted by law, be void ab initio and have no legal effect and, upon written demand by the Corporation, the Purported Transferee shall transfer or cause to be transferred any certificate or other evidence of ownership of the Excess Securities within the Purported Transferee’s possession or control, together with any dividends or other distributions that were received by the Purported Transfer from the Corporation with respect to the Excess Securities (the “Prohibited Distributions”), to an agent designated by the Board (the “Agent”). (A) In the case of a Prohibited Transfer described in Section 2(a)(A) of Article VI, the Agent shall thereupon sell to a buyer or buyers, the Excess Securities transferred to it in one or more arm’s-length transactions (including over a national securities exchange on which the Corporation Securities may be traded, if possible); provided, however, that the Agent, in its sole discretion, shall effect such sale or sales in an orderly fashion and shall not be required to effect any such sale within any specific time frame if, in the Agent’s discretion, such sale or sales would disrupt the market for the Corporation Securities or otherwise would adversely affect the value of the Corporation Securities. If the Purported Transferee has resold the Excess Securities before receiving the Corporation’s demand to surrender the Excess Securities to the Agent, the Purported Transferee shall be deemed to have sold the Excess Securities for the Agent, and shall be required, to the fullest extent permitted by law, to transfer to the Agent any Prohibited Distributions and proceeds of such sale, except to the extent that the Corporation grants written permission to the Purported Transferee to retain a portion of such sales proceeds not exceeding the amount that the Purported Transferee would have received from the Agent pursuant to Section 3(c) of Article VI if the Agent, rather than the Purported Transferee, had resold the Excess Securities. (B) In
