Notwithstanding the foregoing, if the Board determines in good faith that a Person who would otherwise be an “Acquiring Person” as defined pursuant to the foregoing provisions of this paragraph (a) has become such inadvertently, and such Person divests as promptly as practicable a sufficient number of shares of Common Stock so that such Person would no longer be an “Acquiring Person” as defined pursuant to the foregoing provisions of this paragraph (a), then such Person shall not be deemed an “Acquiring Person” for any purposes of this Agreement.

(e) Section 1(p) is deleted in its entirety and replaced with the following language and is further re-numbered as Section 1(q):

(q) “Qualifying Tender Offer” shall mean a tender or exchange offer for all outstanding shares of Common Stock of the Company determined by a majority of the Board, after receiving advice from one or more investment banking firms to be (i) at a price which is fair to the Company’s shareholders (taking into account all factors which members of the Board deem relevant including, without limitation, the potential long-term value of the Company and the prices which could reasonably be attained if the Company or its assets were sold on an orderly basis designed to realize maximum value, and (ii) otherwise in the best interests of the Company and its shareholders.

(f) Sections 1(s) through (z) are re-numbered as Sections 1(r) through (y).

(g) Section 11(b)(i) is deleted in its entirety and replaced with the following:

(b)(i) For the purpose of any computation hereunder, the “current market price” per share of Common Stock on any date shall be deemed to be the average of the daily closing prices per share of such Common Stock for the 30 consecutive

Trading Days immediately prior to such date; provided, however, that if the current market price per share of the Common Stock is determined during a period following the announcement by the issuer of such Common Stock of (A) a dividend or distribution on such Common Stock payable in shares of such Common Stock or securities exercisable for or convertible into shares of such Common Stock (other than the Rights), or (B) any subdivision, combination or reclassification of such Common Stock, and prior to the expiration of the 30 Trading Day period, as set forth above, after the ex-dividend date for such dividend or distribution, or the record date for such subdivision, combination or reclassification, then, and in each such case, the “current market price” shall be properly adjusted to take into account ex-dividend trading. The closing price for each day shall be the last sale price, regular sway, or, in case no such sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the New York Stock Exchange or, if the shares of Common Stock are not listed or admitted to trading on the New York Stock Exchange, as reported in the principal consolidated transaction reporting system with respect to securities listed or admitted to trading on the principal national securities exchange on which the shares of Common Stock are listed or admitted to trading or, if the shares of Common Stock are not listed or admitted to trading on any national securities exchange, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use or, if on any such date the shares of Common Stock are not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Common Stock selected by the Board of Directors of the Company. If on any such date no market maker is making a market in the Common Stork, the fair value of such shares on such date as determined in good faith by the Board of Directors of the Company shall be used. If the Common Stock is not publicly held or not so listed or traded, the “current market price” per share means the fair value per share as determined in good faith by the Board of Directors of the Company, which determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes.

(h) Section 11(b)(ii) is deleted in its entirety and replaced with the following:

(ii) For the purpose of any computation hereunder, the “current market price” of the Preferred Stock shall be determined in the same manner as set forth above for the Common Stock in Section 11(b)(i). If the current market price for the Preferred Stock cannot be determined in the manner provided above, the “current market price” of the Preferred Stock shall be conclusively deemed to be the current market price of the Common Stock (appropriately adjusted to reflect any stock split, stock dividend, or similar transaction occurring after the date hereof), multiplied by one thousand. For the purpose of any computation hereunder, the value of any securities or assets other than the Preferred Stock or Common Stock of the Company shall be the fair value as determined in good faith by the Board of Directors of the Company, which determination shall be described in a statement filed with the Rights Agent and shall be conclusive for all purposes.

(i) Section 20(c) is deleted in its entirety and replaced with the following:

(c) The Rights Agent shall be liable hereunder only for its own negligence, bad faith or willful misconduct. Anything to the contrary notwithstanding, in no event shall the Rights Agent be liable for special, punitive, indirect, consequential or incidental loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the likelihood of such loss or damage. Any liability of the Rights Agent under this Agreement will be limited to the amount of annual fees paid by the Company to the Rights Agent.

(j) Section 23(a) is deleted in its entirety and replaced with the following:

Section 23. Redemption.

Notwithstanding anything in this Agreement to the contrary, the Rights shall not be exercisable after a Person has become an Acquiring Person until such time as the Company’s right of redemption hereunder has expired.

(k) Section 24(a) is deleted in its entirety and replaced with the following:

Section 24. Exchange. (a) The Board of Directors of the Company may, at its option, at any time after any Person becomes an Acquiring Person, mandatorily exchange all or part of the then outstanding and exercisable Rights (which shall not include Rights that have become void pursuant to Section 7(e)) for shares of Common Stock at an exchange ratio of one share of Common Stock per Right, appropriately adjusted to reflect any stock split, stock dividend, or similar transaction occurring after the date hereof (such exchange ratio being hereinafter referred to as the “Exchange Ratio”). If the Board of Directors of the Company elects to exchange all the Rights for Common Stock pursuant to this Section 24 prior to the physical distribution of the Rights Certificates, the Corporation may distribute the Common Stock issuable in the exchange in lieu of distributing Right Certificates, in which case for purposes of this Rights Agreement holders of Rights shall be deemed to have simultaneously received and surrendered for exchange Right Certificates on the date of such distribution. Notwithstanding the foregoing, the Board of Directors shall not be empowered to effect such exchange at any time after any Person (other than the Company, any of its Subsidiaries, any employee benefit plan of the Company or any of its Subsidiaries, or any entity holding shares of Common Stock for or pursuant to the terms of any such plan), together with all Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or more of the shares of Common Stock then outstanding.

Upon the delivery of a certificate from an appropriate officer of the Company which states that the proposed supplement or amendment is in compliance with the terms of this Section, the Rights Agent shall execute such supplement or amendment.

Unless otherwise notified, the Rights Agent shall always be entitled to assume that the Board of Directors of the Company acted in good faith and the Rights Agent shall be fully protected and shall incur no liability in reliance thereon.
