          Section 1.          Certain Definitions. For purposes of this Plan, the following terms have the meaning indicated:

            (a)          “Acquiring Person” shall mean any Person (other than any Exempt Person) that has become, in itself or, together with all Affiliates and Associates of such Person, the Beneficial Owner of 4.99% or more of the shares of Common Stock then outstanding; provided, however, that any Existing Holder (as defined below) will not be deemed to be an Acquiring Person for any purpose of this Plan on and after the date on which the adoption of this Plan is first publicly announced unless and until such time as such Existing Holder acquires Beneficial Ownership of additional shares of Common Stock representing .5% of the Common Stock then outstanding, unless, upon becoming the Beneficial Owner of such additional shares of Common Stock, such Person is not then the Beneficial Owner of 4.99% or more of the shares of Common Stock then outstanding; provided, further, that a Person will not be deemed to have become an

Acquiring Person solely as a result of (i) a reduction in the number of shares of Common Stock outstanding, (ii) the exercise of any options, warrants, rights or similar interests (including restricted stock) granted by the Company to its directors, officers and employees, (iii) any unilateral grant of any security by the Company or any issuance by the Company of shares of its capital stock to such Person, or (iv) an Exempt Transaction, unless and until such time as such Person thereafter acquires Beneficial Ownership of one additional share of Common Stock (other than pursuant to a dividend or distribution paid or made by the Company on the outstanding Common Stock or pursuant to a split or subdivision of the outstanding Common Stock), unless, upon becoming the Beneficial Owner of such additional share of Common Stock, such Person is not then the Beneficial Owner of 4.99% or more of the shares of Common Stock then outstanding. 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 Section 1(a), has become such inadvertently (including, without limitation, because (A) such Person was unaware that it beneficially owned a percentage of Common Stock that would otherwise cause such Person to be an “Acquiring Person” or (B) such Person was aware of the extent of its Beneficial Ownership of Common Stock but had no actual knowledge of the consequences of such Beneficial Ownership under this Plan), 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 Section 1(a), then such Person shall not be deemed to be or to have become an “Acquiring Person” for purposes of this Plan as a result of such inadvertent acquisition. In addition, notwithstanding the foregoing, if a Person who would otherwise be an “Acquiring Person,” as defined pursuant to the foregoing provisions of this Section 1(a), has become such as a result of an acquisition of Beneficial Ownership of shares of Common Stock that the Board in its sole discretion determines in good faith, prior to the Distribution Date that would otherwise occur as a result of such acquisition, will not jeopardize or endanger the availability to the Company of the NOLs, then such Person shall not be deemed to be or to have become an “Acquiring Person” for purposes of this Plan as a result of such acquisition, unless and until such time as such Person thereafter acquires Beneficial Ownership of one additional share of Common Stock (other than pursuant to a dividend or distribution paid or made by the Company on the outstanding Common Stock or pursuant to a split or subdivision of the outstanding Common Stock), unless, upon becoming the Beneficial Owner of such additional share of Common Stock, such Person is not then the Beneficial Owner of 4.99% or more of the shares of Common Stock then outstanding or the Board determines otherwise in accordance with this sentence or the preceding sentence. For all purposes of this Plan, any calculation of the number of shares of Common Stock outstanding at any particular time, including for purposes of determining the particular percentage of the outstanding shares of Common Stock of which any Person is the Beneficial Owner, shall be made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act (as defined below) as in effect on the date hereof.

          (b)          “Affiliate” and “Associate” shall have the respective meanings ascribed to such terms in Rule 12b-2 of the General Rules and Regulations under the Exchange Act, as in effect on the date hereof, and to the extent not included within the foregoing clause

of this Section 1(b), shall also include, with respect to any Person, any other Person (whether or not an Exempt Person) whose shares of Common Stock would be deemed constructively owned by such first Person, owned by a single “entity” as defined in Section 1.382-3(a)(1) of the Treasury Regulations, or otherwise aggregated with shares owned by such first Person pursuant to the provisions of the Code, or any successor provision or replacement provisions to Section 382, and the Treasury Regulations thereunder, provided, however, that a Person shall not be deemed to be the Affiliate or Associate of another Person solely because either or both Persons are or were directors of the Company.

          (c)          A Person shall be deemed the “Beneficial Owner” of, shall be deemed to have “Beneficial Ownership” of and shall be deemed to “beneficially own” any securities:

               (i)          which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has the right to acquire (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding (whether or not in writing) (including any purchase orders for shares of Common Stock initiated prior to the first public announcement of the adoption of this Plan) or upon the exercise of conversion rights, exchange rights, warrants, options, or other rights (in each case, other than upon exercise or exchange of the Rights); provided, however, that a Person shall not be deemed the “Beneficial Owner” of, or to “beneficially own” securities (including rights, options or warrants) which are convertible or exchangeable into or exercisable for Common Stock until such time as such securities are converted or exchanged into or exercised for Common Stock except to the extent the acquisition or transfer of such rights, options or warrants would be treated as exercised on the date of its acquisition or transfer under Section 1.382-4(d) of the Treasury Regulations; provided, further, that a Person shall not be deemed the Beneficial Owner of, or to beneficially own, securities tendered pursuant to a tender or exchange offer made by such Person or any of such Person’s Affiliates or Associates until such tendered securities are accepted for purchase or exchange;

               (ii)         which such Person or any of such Person’s Affiliates or Associates, directly or indirectly, has or shares the right to vote or dispose of, or has “beneficial ownership” of (as defined under Rule 13d-3 of the General Rules and Regulations under the Exchange Act), including pursuant to any agreement, arrangement or understanding (whether or not in writing), but only if the effect of such agreement, arrangement or understanding is to treat such Persons as an “entity” under Section 1.382-3(a)(1) of the Treasury Regulations; or

               (iii)        of which any other Person is the Beneficial Owner, if such Person or any of such Person’s Affiliates or Associates has any agreement, arrangement or understanding (whether or not in writing) with such other Person (or any of such other Person’s Affiliates or Associates) with respect to acquiring, holding, voting or disposing of such securities of the Company, but only if the effect of such agreement, arrangement or understanding is to treat such Persons as an

“entity” under Section 1.382-3(a)(1) of the Treasury Regulations; provided, however, that a Person shall not be deemed the Beneficial Owner of, or to beneficially own, any security (A) if such Person has the right to vote such security pursuant to an agreement, arrangement or understanding (whether or not in writing) which (1) arises solely from a revocable proxy or consent given to such Person in response to a public proxy or consent solicitation made pursuant to, and in accordance with, the applicable rules and regulations promulgated under the Exchange Act and (2) is not also then reportable on Schedule 13D or Schedule 13G under the Exchange Act (or any comparable or successor report), or (B) if such Beneficial Ownership arises solely as a result of such Person’s status as a “clearing agency,” as defined in Section 3(a)(23) of the Exchange Act; provided, further, that nothing in this Section 1(c) shall cause a Person engaged in business as an underwriter of securities or member of a selling group to be the Beneficial Owner of, or to beneficially own, any securities acquired through such Person’s participation in good faith in an underwriting syndicate until the expiration of 40 calendar days after the date of such acquisition, or such later date as the Board may determine in any specific case. Notwithstanding anything herein to the contrary, to the extent not within the foregoing provisions of this Section 1(c), a Person shall be deemed the Beneficial Owner of, and shall be deemed to beneficially own or have Beneficial Ownership of, securities which such Person would be deemed to constructively own or which otherwise would be aggregated with shares owned by such Person pursuant to Section 382 of the Code, or any successor provision or replacement provision and the Treasury Regulations thereunder.

As soon as practicable after the Distribution Date, the Company will prepare and execute, the Rights Agent will countersign and the Company will send or cause to be sent (and the Rights Agent will, if requested, send) by first-class, postage-prepaid mail, to each record holder of Common Stock as of the close of business on the Distribution Date (other than any Acquiring Person or any Associate or Affiliate of an Acquiring Person), at the address of such holder shown on the records of the Company, a Right Certificate, in substantially the form of Exhibit B hereto (a “Right Certificate”), evidencing one Right (subject to adjustment as provided herein) for each share of Common Stock so held. As of and after the Distribution Date, the Rights will be evidenced solely by such Right Certificates.

          (b)          As promptly as practicable following the Record Date, the Company will send a copy of a Summary of Rights to Purchase Shares of Preferred Stock, in substantially the form of Exhibit C hereto (the “Summary of Rights”), by first-class, postage-prepaid mail, to each record holder of Common Stock as of the Close of Business on the Record Date (other than any Acquiring Person or any Associate or Affiliate of any Acquiring Person), at the address of such holder shown on the records of the Company. With respect to certificates representing Common Stock (or Book Entry shares of Common Stock) outstanding as of the Record Date, until the Distribution Date, the Rights will be evidenced by such certificates registered in the names of the holders thereof (or the Book Entry shares). Until the Distribution Date (or, if earlier, the Expiration Date), the surrender for transfer of any certificate for Common Stock (or any Book Entry shares of Common Stock) outstanding on the Record Date shall also constitute the transfer of the Rights associated with the Common Stock represented by such certificate or Book Entry shares.

          (c)          Rights shall be issued in respect of all shares of Common Stock issued or disposed of after the Record Date but prior to the earlier of the Distribution Date and the Expiration Date (or in certain circumstances provided in Section 21 hereof, after the Distribution Date). Certificates issued for Common Stock after the Record Date but prior to the earlier of the Distribution Date and the Expiration Date (or in certain circumstances provided in Section 22 hereof, after the Distribution date) shall have impressed on, printed on, written on or otherwise affixed to them the following legend:

            (a)      (i)   In the event the Company shall at any time after the date of this Plan (A) declare a dividend on the Preferred Stock payable in shares of Preferred Stock, (B) subdivide the outstanding shares of Preferred Stock, (C) combine the outstanding shares of Preferred Stock into a smaller number of shares of Preferred Stock or (D) issue any shares of its capital stock in a reclassification of the Preferred Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing or surviving corporation), except as otherwise provided in this Section 11(a), the Purchase Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or reclassification, as the case may be, and the number and kind of shares of capital stock issuable on such date, shall be proportionately adjusted so that the holder of any Right exercised after such time shall be entitled to receive the aggregate number and kind of shares of capital stock which, if such Right had been exercised immediately prior to such date and at a time when the Preferred Stock transfer books of the Company were open, the holder would have owned upon such exercise and been entitled to receive by virtue of such dividend, subdivision, combination or reclassification.

           (ii)          Subject to Section 23 of this Plan, and except as otherwise provided in this Section 11(a)(ii) and Section 11(a)(iii), in the event that any Person becomes an Acquiring Person, each holder of a Right shall thereafter have the right to receive, upon exercise thereof at a price equal to the then-current Purchase Price, in accordance with the terms of this Plan and in lieu of shares of Preferred Stock, such number of shares of Common Stock (or at the option of the Company, such number of one-millionths of a share of Preferred Stock) as shall equal the result obtained by multiplying (x) the then-current Purchase Price, by (y) the number of one-millionths of a share of Preferred Stock for which a Right is then exercisable and dividing the product of (x) and (y) by (z) 50% of the then-current per share market price of the Common Stock (determined pursuant to Section 11(d) hereof) on the date of the occurrence of such event; provided, however, that the Purchase Price (as so adjusted) and the number of shares of Common Stock so receivable upon exercise of a Right shall thereafter be subject to further adjustment as appropriate in accordance with this Section 11 hereof. Notwithstanding anything in this Plan to the contrary, however, from and after the time (the “Invalidation Time”) when any Person first becomes an Acquiring Person, any Rights that are beneficially owned by (x) any Acquiring Person (or any Affiliate or Associate of any Acquiring Person), (y) a transferee of any Acquiring Person (or any such Affiliate or Associate) who becomes a transferee after the Invalidation Time or (z) a transferee of any Acquiring Person (or any such Affiliate or Associate) who became a transferee prior to or concurrently with the Invalidation Time pursuant to either (I) a transfer from the Acquiring Person to holders of its equity securities or to any Person with whom it has any continuing agreement, arrangement or understanding regarding the transferred

Rights or (II) a transfer that the Board has determined is part of a plan, arrangement or understanding which has the purpose or effect of avoiding the provisions of this paragraph, and subsequent transferees of such Persons, shall be void without any further action and any holder of such Rights shall thereafter have no rights whatsoever with respect to such Rights under any provision of this Plan. The Company shall use all reasonable efforts to ensure that the provisions of this Section 11(a)(ii) are complied with, but shall have no liability to any holder of Right Certificates or other Person as a result of its failure to make any determinations with respect to an Acquiring Person or its Affiliates, Associates or transferees hereunder. From and after the Invalidation Time, no Right Certificate shall be issued pursuant to Section 3 or Section 6 hereof that represents Rights that are or have become void pursuant to the provisions of this paragraph, and any Right Certificate delivered to the Rights Agent that represents Rights that are or have become void pursuant to the provisions of this paragraph shall be canceled.

           (iii)          The Company may at its option (or, if required to comply with its Certificate of Incorporation, shall) substitute for a share of Common Stock issuable upon the exercise of Rights in accordance with the foregoing subparagraph (ii) such number or fraction of shares of Preferred Stock (or, if required to comply with its Certificate of Incorporation, equivalent shares of its capital stock) having an aggregate current market value equal to the current per share market price of a share of Common Stock. In the event that there shall be an insufficient number of shares of Common Stock authorized but unissued (and unreserved) to permit the exercise in full of the Rights in accordance with the foregoing subparagraph (ii), the Board shall, with respect to such deficiency, to the extent permitted by applicable law and any material agreements then in effect to which the Company is a party, (A) determine the excess of (x) the value of the shares of Common Stock issuable upon the exercise of a Right in accordance with the foregoing subparagraph (ii) (the “Current Value”) over (y) the then-current Purchase Price multiplied by the number of one-millionths of a share of Preferred Stock for which a Right was exercisable immediately prior to the time that the Acquiring Person became such (such excess, the “Spread”), and (B) with respect to each Right (other than Rights which have become void pursuant to Section 11(a)(ii)), make adequate provision to substitute for the shares of Common Stock issuable in accordance with subparagraph (ii) upon exercise of the Right and payment of the applicable Purchase Price, (1) cash, (2) a reduction in such Purchase Price, (3) shares of Preferred Stock or other equity securities of the Company (including, without limitation, shares or fractions of shares of preferred stock which, by virtue of having dividend, voting and liquidation rights substantially comparable to those of the shares of Common Stock, are deemed in good faith by the Board to have substantially the same value as the shares of Common Stock (such shares of preferred stock and shares or fractions of shares of preferred stock are hereinafter referred to as “Common Stock Equivalents”)), (4) debt securities of the Company, (5) other assets, or (6) any combination of the foregoing, having a value which, when added to the value of the shares of Common Stock actually issued upon exercise of such Right, shall have an aggregate value equal to the Current Value (less the amount of any reduction in

such Purchase Price), where such aggregate value has been determined by the Board upon the advice of a nationally recognized investment banking firm selected in good faith by the Board; provided, however, that if the Company shall not make adequate provision to deliver value pursuant to clause (B) above within thirty (30) days following the date that the Acquiring Person became such (the “Section 11(a)(ii) Trigger Date”), then the Company shall be obligated to deliver, to the extent permitted by applicable law and any material agreements then in effect to which the Company is a party, upon the surrender for exercise of a Right and without requiring payment of such Purchase Price, shares of Common Stock (to the extent available), and then, if necessary, such number or fractions of shares of Preferred Stock (to the extent available) and then, if necessary, cash, which shares and/or cash have an aggregate value equal to the Spread. If, within the thirty (30) day period referred to above the Board shall determine in good faith that it is likely that sufficient additional shares of Common Stock could be authorized for issuance upon exercise in full of the Rights, then, if the Board elects, such thirty (30) day period may be extended to the extent necessary, but not more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in order that the Company may seek stockholder approval for the authorization of such additional shares (such thirty (30) day period, as it may be extended, is hereinafter called the “Substitution Period”). To the extent that the Company determines that some action need be taken pursuant to the second and/or third sentence of this Section 11(a)(iii), the Company (x) shall provide, subject to Section 11(a)(ii) hereof and the last sentence of this Section 11(a)(iii) hereof, that such action shall apply uniformly to all outstanding Rights and (y) may suspend the exercisability of the Rights until the expiration of the Substitution Period in order to seek any authorization of additional shares and/or to decide the appropriate form of distribution to be made pursuant to such second sentence and to determine the value thereof. In the event of any such suspension, the Company shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension is no longer in effect. For purposes of this Section 11(a)(iii), the value of the shares of Common Stock shall be the current per share market price (as determined pursuant to Section 11(d)(i)) on the Section 11(a)(ii) Trigger Date and the per share or fractional value of any “Common Stock Equivalent” shall be deemed to equal the current per share market price of the Common Stock on such date. The Board may, but shall not be required to, establish procedures to allocate the right to receive shares of Common Stock upon the exercise of the Rights among holders of Rights pursuant to this Section 11(a)(iii).

           (b)          In case the Company shall fix a record date for the issuance of rights, options or warrants to all holders of Preferred Stock entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Preferred Stock (or shares having similar rights, privileges and preferences as the Preferred Stock (“Equivalent Preferred Shares”)) or securities convertible into Preferred Stock or Equivalent Preferred Shares at a price per share of Preferred Stock or Equivalent Preferred Shares (or having a conversion price per share, if a security convertible into shares of Preferred Stock or Equivalent Preferred Shares) less than the then current per

share market price of the Preferred Stock (determined pursuant to Section 11(d) hereof) on such record date, the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the number of shares of Preferred Stock and Equivalent Preferred Shares outstanding on such record date plus the number of shares of Preferred Stock and Equivalent Preferred Shares which the aggregate offering price of the total number of such shares so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such current market price, and the denominator of which shall be the number of shares of Preferred Stock and Equivalent Preferred Shares outstanding on such record date plus the number of additional shares of Preferred Stock and/or Equivalent Preferred Shares to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible); provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock of the Company issuable upon exercise of one Right. In case such subscription price may be paid in a consideration part or all of which shall be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board, whose determination shall be described in a statement filed with the Rights Agent and which shall be binding on the Rights Agent. Shares of Preferred Stock and Equivalent Preferred Shares owned by or held for the account of the Company shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed; and in the event that such rights, options or warrants are not so issued, the Purchase Price shall be adjusted to be the Purchase Price which would then be in effect if such record date had not been fixed.

            (c)          In case the Company shall fix a record date for the making of a distribution to all holders of the Preferred Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing or surviving corporation) of evidences of indebtedness or assets (other than a regular cash dividend or a dividend payable in Preferred Stock) or subscription rights or warrants (excluding those referred to in Section 11(b) hereof), the Purchase Price to be in effect after such record date shall be determined by multiplying the Purchase Price in effect immediately prior to such record date by a fraction, the numerator of which shall be the then-current per share market price of the Preferred Stock (determined pursuant to Section 11(d) hereof) on such record date, less the fair market value (as determined in good faith by the Board whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent) of the portion of such assets or evidences of indebtedness so to be distributed or of such subscription rights or warrants applicable to one share of Preferred Stock, and the denominator of which shall be such current per share market price of the Preferred Stock; provided, however, that in no event shall the consideration to be paid upon the exercise of one Right be less than the aggregate par value of the shares of capital stock of the Company to be issued upon exercise of one Right. Such adjustments shall be made successively whenever such a record date is fixed; and in the event that such distribution is not so made, the Purchase Price shall again be adjusted to be the Purchase Price that would then be in effect if such record date had not been fixed.

            (d)          (i)          Except as otherwise provided herein, for the purpose of any computation hereunder, the “current per share market price” of any security (a “Security” for the purpose of this Section 11(d)(i)) on any date shall be deemed to be the average of the daily closing prices per share of such Security for the 30 consecutive Trading Days (as such term is hereinafter defined) immediately prior to such date; provided, however, that in the event that the current per share market price of the Security is determined during a period following the announcement by the issuer of such Security of (A) a dividend or distribution on such Security payable in shares of such Security or securities convertible into such shares, or (B) any subdivision, combination or reclassification of such Security, and prior to the expiration of 30 Trading Days 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 per share market price shall be appropriately adjusted to reflect the current market price per share equivalent of such Security. The closing price for each day shall be the last sale price, regular way, or, in case no such sale takes place on such day, the last quoted price or, if on such date the Security is not so quoted or reported, the average of the high and low asked prices in the over-the-counter market as reported by any system then in use, or, if not so quoted, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Security selected by the Board. The term “Trading Day” shall mean a day on which the principal national securities exchange on which the Security is listed or admitted to trading is open for the transaction of business or, if the Security is not listed or admitted to trading on any national securities exchange, a Business Day.

              (ii)         For the purpose of any computation hereunder, if the Preferred Stock is publicly traded, the “current per share market price” of the Preferred Stock shall be determined in accordance with the method set forth in Section 11(d)(i). If the Preferred Stock is not publicly traded but the Common Stock is publicly traded, the “current per share market price” of the Preferred Stock shall be conclusively deemed to be the current per share market price of the Common Stock as determined pursuant to Section 11(d)(i) multiplied by the then applicable Adjustment Number (as defined in and determined in accordance with the Certificate of Designation for the Preferred Stock). If neither the Common Stock nor the Preferred Stock is publicly traded, “current per share market price” shall mean the fair value per share as determined in good faith by the Board, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent.

           (e)         No adjustment in the Purchase Price shall be required unless such adjustment would require an increase or decrease of at least 1% in the Purchase Price; provided, however, that any adjustments not required to be made by reason of this Section 11(e) shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 11 shall be made to the nearest cent or to the nearest one ten-millionth of a share of Preferred Stock or share of Common Stock or other share or security as the case may be. Notwithstanding the first sentence of this Section 11(e), any adjustment required by this Section 11 shall be made no later than the earlier of (i) three years from the date of the transaction which requires such adjustment or (ii) the Expiration Date. If as a result of an adjustment made pursuant to Section 11(a)

hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares of capital stock of the Company other than the Preferred Stock, thereafter the Purchase Price and the number of such other shares so receivable upon exercise of a Right shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Preferred Stock contained in Sections 11(a), 11(b), 11(c), 11(e), 11(h), 11(i) and 11(m) and the provisions of Sections 7, 9, 10 and 13 hereof with respect to the Preferred Stock shall apply on like terms to any such other shares.

          (f)          All Rights originally issued by the Company subsequent to any adjustment made to the Purchase Price hereunder shall evidence the right to purchase, at the adjusted Purchase Price, the number of one one-millionths of a share of Preferred Stock purchasable from time to time hereunder upon exercise of the Rights, all subject to further adjustment as provided herein.

          (g)          Unless the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Purchase Price as a result of the calculations made in Sections 11(b) and 11(c), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Purchase Price, that number of one one-millionths of a share of Preferred Stock (calculated to the nearest ten-millionth of a share of Preferred Stock) obtained by (i) multiplying (x) the number of one-millionths of a share of Preferred Stock purchasable upon the exercise of a Right immediately prior to such adjustment by (y) the Purchase Price in effect immediately prior to such adjustment of the Purchase Price and (ii) dividing the product so obtained by the Purchase Price in effect immediately after such adjustment of the Purchase Price.

          (h)          The Company may elect on or after the date of any adjustment of the Purchase Price or any adjustment made to the number of shares of Preferred Stock for which a Right may be exercised pursuant to Section 11(a)(i), 11(b) or 11(c) hereof to adjust the number of Rights, in substitution for any adjustment in the number of one one-millionths of a share of Preferred Stock purchasable upon the exercise of a Right. Each of the Rights outstanding after such adjustment of the number of Rights shall be exercisable for the number of one one-millionths of a share of Preferred Stock for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest ten-millionth) obtained by dividing the Purchase Price in effect immediately prior to adjustment of the Purchase Price by the Purchase Price in effect immediately after adjustment of the Purchase Price. The Company shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the Purchase Price is adjusted or any day thereafter, but, if the Right Certificates have been issued, shall be at least 10 days later than the date of the public announcement. If Right Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Section 11(i), the Company may, as promptly as practicable, cause to be distributed to holders of record of Right Certificates on such record date Right Certificates evidencing, subject to Section 13

hereof, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Right Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Right Certificates evidencing all the Rights to which such holders shall be entitled as a result of such adjustment. Right Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein and shall be registered in the names of the holders of record of Right Certificates on the record date specified in the public announcement.

          (i)          Irrespective of any adjustment or change in the Purchase Price or the number of one one-millionths of a share of Preferred Stock issuable upon the exercise of the Rights, the Right Certificates theretofore and thereafter issued may continue to express the Purchase Price and the number of one-millionths of a share of Preferred Stock which were expressed in the initial Right Certificates issued hereunder without effect on the Purchase Price payable to exercise a Right or the number of one one-millionths of a share of Preferred Stock issuable upon the exercise of a Right as provided herein.

          (j)          Before taking any action that would cause an adjustment reducing the Purchase Price below the then par value, if any, of the shares of Preferred Stock or other shares of capital stock issuable upon exercise of the Rights, the Company shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable shares of Preferred Stock or other such shares at such adjusted Purchase Price.

         (k)          In any case in which this Section 11 shall require that an adjustment in the Purchase Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event issuing to the holder of any Right exercised after such record date the Preferred Stock, Common Stock or other capital stock or securities of the Company, if any, issuable upon such exercise over and above the Preferred Stock, Common Stock or and other capital stock or securities of the Company, if any, issuable upon such exercise on the basis of the Purchase Price in effect prior to such adjustment; provided, however, that the Company shall deliver to such holder a due ▇▇▇▇ or other appropriate instrument evidencing such holder’s right to receive such additional shares upon the occurrence of the event requiring such adjustment.

          (l)          Notwithstanding anything in this Section 11 to the contrary, the Company shall be entitled to make such adjustments in the Purchase Price, in addition to those adjustments expressly required by this Section 11, as and to the extent that the Board in its sole discretion shall determine to be advisable in order that any consolidation or subdivision of the Preferred Stock, issuance wholly for cash of any shares of Preferred Stock at less than the current market price, issuance wholly for cash of Preferred Stock or securities which by their terms are convertible into or exchangeable for Preferred Stock, dividends on Preferred Stock payable in shares of Preferred Stock or issuance of rights, options or warrants referred to hereinabove in Section 11(b), hereafter made by the Company to holders of its Preferred Stock shall not be taxable to such stockholders.

          (m)          Notwithstanding anything in this Plan to the contrary, in the event that at any time after the date of this Plan and prior to the Distribution Date, the Company shall (i) declare and pay any dividend on the Common Stock payable in Common Stock, or (ii) effect a subdivision, combination or consolidation of the Common Stock (by reclassification or otherwise than by payment of a dividend payable in Common Stock) into a greater or lesser number of shares of Common Stock, then, in any such case, the number of Rights associated with each share of Common Stock then outstanding, or issued or delivered thereafter, shall be proportionately adjusted so that the number of Rights thereafter associated with each share of Common Stock following any such event shall equal the result obtained by multiplying the number of Rights associated with each share of Common Stock immediately prior to such event by a fraction the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to the occurrence of the event and the denominator of which shall be the total number of shares of Common Stock outstanding immediately following the occurrence of such event.

          (n)          The Company agrees that, after the earlier of the Distribution Date or the Stock Acquisition Date, it will not, except as permitted by Section 22, 23 or 26 hereof, take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or eliminate the benefits intended to be afforded by the Rights.

          Section 12.        Certificate of Adjusted Purchase Price or Number of Shares. Whenever an adjustment is made as provided in Section 11 hereof, the Company shall promptly (a) prepare a certificate setting forth such adjustment, and a brief statement of the facts accounting for such adjustment, (b) file with the Rights Agent and with each transfer agent for the Common Stock or the Preferred Stock a copy of such certificate and (c) mail a brief summary thereof to each holder of a Right Certificate (or if prior to the Distribution Date, to each holder of a certificate representing shares of Common Stock or Book Entry shares in respect thereof) in accordance with Section 25 hereof. The Rights Agent shall be fully protected in relying on any such certificate and on any adjustment therein contained and shall not be deemed to have knowledge of any such adjustment unless and until it shall have received such certificate. Any adjustment to be made pursuant to Section 11 hereof shall be effective as of the date of the event giving rise to such adjustment.

          Section 13.        Fractional Rights and Fractional Shares.

          (a)          The Company shall not be required to issue fractions of Rights (except prior to the Distribution Date in accordance with Section 11(n) hereof) or to distribute Right Certificates which evidence fractional Rights. In lieu of such fractional Rights, there shall be paid to the registered holders of the Right Certificates with regard to which such fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the current market value of a whole Right. For the purposes of this Section 13(a), the current market value of a whole Right shall be the closing price of the Rights for the Trading Day immediately prior to the date on which such fractional Rights would have been otherwise issuable. The closing price for any day shall be the last sale price, regular way, 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 on the principal national securities exchange on which the Rights are listed or admitted to trading or, if the Rights 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 such system then in use or, if on any such date the Rights are not so quoted, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Rights selected by the Board. If on any such date no such market maker is making a market in the Rights, the fair value of the Rights on such date as determined in good faith by the Board shall be used.

          (b)          The Company shall not be required to issue fractions of Preferred Stock (other than fractions which are integral multiples of one one-millionth of a share of Preferred Stock) or to distribute certificates which evidence fractional shares of Preferred Stock (other than fractions which are integral multiples of one one-millionth of a share of Preferred Stock) upon the exercise or exchange of Rights. Interests in fractions of Preferred Stock in integral multiples of one one-millionth of a share of Preferred Stock may, at the election of the Company, be evidenced by depositary receipts, pursuant to an appropriate agreement between the Company and a depositary selected by it; provided that such agreement shall provide that the holders of such depositary receipts shall have all the rights, privileges and preferences to which they are entitled as beneficial owners (for the purposes of this Section 13(b), as such term is defined in Rule 13d-3 or 13d-5 of the General Rules and Regulations under the Exchange Act) of the Preferred Stock represented by such depositary receipts. In lieu of fractional shares of Preferred Stock that are not integral multiples of one one-millionth of a share of Preferred Stock, the Company shall pay to the registered holders of Right Certificates at the time such Rights are exercised for shares of Preferred Stock as herein provided an amount in cash equal to the same fraction of the current market value of one share of Preferred Stock. For the purposes of this Section 13(b), the current market value of a share of Preferred Stock shall be the closing price of a share of Preferred Stock (as determined pursuant to Section 11(d)(ii) hereof) for the Trading Day immediately prior to the date of such exercise.

          (c)          The Company shall not be required to issue fractions of shares of Common Stock or to distribute certificates which evidence fractional shares of Common Stock upon the exercise or exchange of Rights. In lieu of such fractional shares of Common Stock, the Company shall pay to the registered holders of the Right Certificates at the time such Rights are exercised or exchanged for shares of Common Stock as herein provided an amount in cash equal to the same fraction of the current market value of a whole share of Common Stock (as determined in accordance with Section 11(d)(i) hereof), for the Trading Day immediately prior to the date of such exercise or exchange.

          (d)          The holder of a Right by the acceptance of the Right expressly waives his right to receive any fractional Rights or any fractional shares upon exercise or exchange of a Right (except as provided above).

         Section 14.        Rights of Action. All rights of action in respect of this Plan, excepting the rights of action given to the Rights Agent under Section 17 hereof, are vested in the respective

          (a)          prior to the Distribution Date, the Rights will not be evidenced by a Right Certificate and will be transferable only in connection with the transfer of the Common Stock;

          (b)          after the Distribution Date, the Right Certificates are transferable only on the registry books of the Rights Agent if surrendered at the office or agency of the Rights Agent designated for such purpose, duly endorsed or accompanied by a proper instrument of transfer;

          (c)          the Company and the Rights Agent may deem and treat the Person in whose name the Right Certificate (or, prior to the Distribution Date, the Common Stock certificate (or Book Entry shares in respect of Common Stock)) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on the Right Certificates or the Common Stock certificate (or notices provided to holders of Book Entry shares of Common Stock) made by anyone other than the Company or the Rights Agent) for all purposes whatsoever, and neither the Company nor the Rights Agent, subject to Section 7(e) hereof, shall be affected by any notice to the contrary; and

          (d)          notwithstanding anything in this Plan to the contrary, neither the Company nor the Rights Agent shall have any liability to any holder of a Right or other Person as a result of its inability to perform any of its obligations under this Plan by reason of any preliminary or permanent injunction or other order, judgment, decree or ruling (whether interlocutory or final) issued by a court or by a governmental, regulatory, self-regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation; provided, however, that the Company must use its reasonable best efforts to have any such injunction, order, judgment, decree or ruling lifted or otherwise overturned as soon as possible.

           (a)          The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements incurred in the administration and execution of this Plan and the exercise and performance of its duties hereunder. The Company also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability or expense, incurred without gross negligence, bad faith or willful misconduct on the part of the Rights Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Plan, including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly.

          (b)          The Rights Agent shall be protected and shall incur no liability for, or in respect of any action taken, suffered or omitted by it in connection with, its administration of this Plan in reliance upon any Right Certificate or certificate for the Preferred Stock, the Common Stock or for any other securities of the Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement or other paper or document reasonably believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons, or otherwise upon the advice of counsel as set forth in Section 19 hereof.

         Section 18.        Merger or Consolidation or Change of Name of Rights Agent.

          (a)          Any corporation or entity into which the Rights Agent or any successor Rights Agent may be merged or with which it may be consolidated, or any entity corporation or resulting from any merger or consolidation to which the Rights Agent or any successor Rights Agent shall be a party, or any corporation or entity succeeding to the stock transfer or corporate trust powers of the Rights Agent or any successor Rights Agent, shall be the successor to the Rights Agent under this Plan without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided that such corporation or entity would be eligible for appointment as a successor Rights Agent under the provisions of Section 20 hereof. In case at the time such successor Rights Agent shall succeed to the agency created by this Plan, any of the Right Certificates shall

have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Right Certificates so countersigned; and in case at that time any of the Right Certificates shall not have been countersigned, any successor Rights Agent may countersign such Right Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Plan.

          (b)          In case at any time the name of the Rights Agent shall be changed and at such time any of the Right Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Right Certificates so countersigned; and in case at that time any of the Right Certificates shall not have been countersigned, the Rights Agent may countersign such Right Certificates either in its prior name or in its changed name and in all such cases such Right Certificates shall have the full force provided in the Right Certificates and in this Plan.

          Section 19.      Duties of Rights Agent. The Rights Agent undertakes the duties and obligations imposed by this Plan upon the following terms and conditions, by all of which the Company and the holders of Right Certificates, by their acceptance thereof, shall be bound:

          (a)          The Rights Agent may consult with legal counsel (who may be legal counsel for the Company and/or the Board), and the opinion of such counsel shall be full and complete authorization and protection to the Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion.

          (b)          Whenever in the performance of its duties under this Plan the Rights Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by the President and the Secretary of the Company (each, an “Authorized Officer”) and delivered to the Rights Agent; and such certificate shall be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Plan in reliance upon such certificate.

          (c)          The Rights Agent shall be liable hereunder to the Company and any other Person only for its own gross negligence, bad faith or willful misconduct.

          (d)          The Rights Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Plan or in the Right Certificates (except its countersignature thereof) or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by the Company only.

          (e)          The Rights Agent shall not be under any responsibility in respect of the validity of this Plan or the execution and delivery hereof (except the due execution hereof by the Rights Agent) or in respect of the validity or execution of any Right Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the

Company of any covenant or condition contained in this Plan or in any Right Certificate; nor shall it be responsible for any change in the exercisability of the Rights (including the Rights becoming void pursuant to Section 11(a)(ii) hereof) or any adjustment in the terms of the Rights (including the manner, method or amount thereof) provided for in Sections 3, 11, 22 and 23, or the ascertaining of the existence of facts that would require any such change or adjustment (except with respect to the exercise of Rights evidenced by Right Certificates after receipt of a certificate furnished pursuant to Section 12, describing such change or adjustment); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Preferred Stock or other securities to be issued pursuant to this Plan or any Right Certificate or as to whether any shares of Preferred Stock or other securities will, when issued, be validly authorized and issued, fully paid and nonassessable.

          (f)          The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Plan.

          (g)          The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from any person reasonably believed by the Rights Agent to be one of the Authorized Officers of the Company, and to apply to such Authorized Officers for advice or instructions in connection with its duties, and it shall not be liable for any action taken or suffered by it in good faith in accordance with instructions of any such Authorized Officer or for any delay in acting while waiting for those instructions. Any application by the Rights Agent for written instructions from the Company may, at the option of the Rights Agent, set forth in writing any action proposed to be taken or omitted by the Rights Agent under this Plan and the date on and/or after which such action shall be taken or such omission shall be effective. The Rights Agent shall not be liable for any action taken by, or omission of, the Rights Agent in accordance with a proposal included in any such application on or after the date specified in such application (which date shall not be less than five Business Days after the date any Authorized Officer of the Company actually receives such application unless any such Authorized Officer shall have consented in writing to an earlier date) unless, prior to taking any such action (or the effective date in the case of an omission), the Rights Agent shall have received written instructions in response to such application specifying the action to be taken or omitted.

          (h)          The Rights Agent and any stockholder, director, officer or employee of the Rights Agent may buy, sell or deal in any of the Rights or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Rights Agent under this Plan. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Company or for any other legal entity.

          (i)          The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct, provided, that reasonable care was exercised in the selection and continued employment thereof.

          (j)          If, with respect to any Right Certificate surrendered to the Rights Agent for exercise or transfer, the certificate contained in the form of assignment or the form of election to purchase set forth on the reverse thereof, as the case may be, has not been completed to certify the holder is not an Acquiring Person (or an Affiliate or Associate thereof) or a transferee thereof, the Rights Agent shall not take any further action with respect to such requested exercise or transfer without first consulting with the Company.

          (k)          The Rights Agent has no responsibility whatsoever to provide any tax advice to the Company’s shareholders.

          (a)          The Board may, at any time prior to such time as any Person first becomes an Acquiring Person, redeem all but not less than all the then outstanding Rights at a redemption price of $0.001 per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring in respect of the Common Stock after the date hereof (the “Redemption Price”). The redemption of the Rights may be made effective at such time, on such basis and with such conditions as the Board in its sole discretion may establish. The Company may, at its option, pay the Redemption Price in cash, shares of Common Stock (based on the current market price of the Common Stock at the time of redemption as determined pursuant to Section 11(d)(i) hereof) or any other form of consideration deemed appropriate by the Board.

          (b)          Immediately upon the action of the Board ordering the redemption of the Rights pursuant to paragraph (a) of this Section 22 (or at such later time as the Board may establish for the effectiveness of such redemption), and without any further action and without any notice, the right to exercise the Rights will terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price. The Company shall promptly give public notice of any such redemption; provided, however, that the failure to give, or any defect in, any such notice shall not affect the validity of such redemption. Within 10 days after such action of the Board ordering the redemption of the Rights (or such later time as the Board may establish for the effectiveness of such redemption), the Company shall mail a notice of redemption to all the holders of the then outstanding Rights at their last addresses as they appear upon the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the transfer agent for the Common Stock. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of redemption shall state the method by which the payment of the Redemption Price will be

made. The failure to give notice required by this Section 22(b) or any defect therein shall not affect the validity of the action taken by the Company.

          (c)          In the case of a redemption under Section 22(a) hereof, the Company may, at its option, discharge all of its obligations with respect to the Rights by (i) issuing a press release announcing the manner of redemption of the Rights and (ii) mailing payment of the Redemption Price to the registered holders of the Rights at their last addresses as they appear on the registry books of the Rights Agent or, prior to the Distribution Date, on the registry books of the transfer agent of the Common Stock, and upon such action, all outstanding Right Certificates shall be void without any further action by the Company.

          Section 23.       Exchange.

          (a)          The Board may, at its option, at any time after any Person first becomes an Acquiring Person, exchange all or part of the then outstanding Rights (which shall not include Rights that have not become effective or that have become void pursuant to the provisions of Section 11(a)(ii) hereof) for shares of Common Stock at an exchange ratio of one share of Common Stock (or one-millionth of a share of Preferred Stock) per Right, appropriately adjusted to reflect any stock split, stock dividend or similar transaction occurring after the date hereof (such amount per Right being hereinafter referred to as the “Exchange Ratio”). Notwithstanding the foregoing, the Board shall not be empowered to effect such exchange at any time after an Acquiring Person becomes the Beneficial Owner of shares of Common Stock aggregating 50% or more of the voting power of the shares of Common Stock then outstanding. The exchange of the Rights by the Board may be made effective at such time, on such basis and with such conditions as the Board in its sole discretion may establish. Prior to effecting an exchange pursuant to this Section 23, the Board may direct the Company to enter into a Trust Agreement in such form and with such terms as the Board shall then approve (the “Trust Agreement”). If the Board so directs, the Company shall enter into the Trust Agreement and shall issue to the trust created by such agreement (the “Trust”) all of the shares of Common Stock issuable pursuant to the exchange, and all Persons entitled to receive shares pursuant to the exchange shall be entitled to receive such shares (and any dividends or distributions made thereon after the date on which such shares are deposited in the Trust) only from the Trust and solely upon compliance with the relevant terms and provisions of the Trust Agreement.

          (b)          Immediately upon the effectiveness of the action of the Board ordering the exchange of any Rights pursuant to paragraph (a) of this Section 23 and without any further action and without any notice, the right to exercise such Rights shall terminate and the only right thereafter of a holder of such Rights shall be to receive that number of shares of Common Stock equal to the number of such Rights held by such holder multiplied by the Exchange Ratio. The Company shall promptly give public notice of any such exchange and shall promptly mail a notice of any such exchange to all of the holders of the Rights so exchanged at their last addresses as they appear upon the registry books of the Rights Agent; provided, however, that the failure to give, or any defect in, such notice shall not affect the validity of such exchange. Any notice which is mailed in

the manner herein provided shall be deemed given, whether or not the holder receives the notice. Each such notice of exchange will state the method by which the exchange of the shares of Common Stock for Rights will be effected and, in the event of any partial exchange, the number of Rights which will be exchanged. Any partial exchange shall be effected pro rata based on the number of Rights (other than Rights which have become void pursuant to the provisions of Section 11(a)(ii) hereof) held by each holder of Rights.

          (c)          The Company may at its option substitute, and, in the event that there shall not be sufficient shares of Common Stock issued but not outstanding or authorized but unissued (and unreserved) to permit an exchange of Rights as contemplated in accordance with this Section 23 (or if the issuance of Common Stock in exchange for any Rights would not otherwise be permitted under the Certificate of Incorporation), the Company shall substitute, to the extent of such insufficiency or to the extent necessary to comply with its Certificate of Incorporation, for each share of Common Stock that would otherwise be issuable upon exchange of a Right, a number of shares of Preferred Stock or fraction thereof (or Equivalent Preferred Shares, as such term is defined in Section 11(b), or other equivalent shares of its capital stock) such that the current per share market price (determined pursuant to Section 11(d) hereof) of one share of Preferred Stock (or Equivalent Preferred Share or other equivalent share) multiplied by such number or fraction is equal to the current per share market price of one share of Common Stock (determined pursuant to Section 11(d) hereof) as of the date of such exchange.

          Section 24.      Notice of Certain Events.

          (a)          In case the Company shall at any time after the earlier of the Distribution Date or the Stock Acquisition Date propose (i) to pay any dividend payable in stock of any class to the holders of its Preferred Stock or to make any other distribution to the holders of its Preferred Stock (other than a regular quarterly cash dividend), (ii) to offer to the holders of its Preferred Stock rights or warrants to subscribe for or to purchase any additional shares of Preferred Stock or shares of stock of any class or any other securities, rights or options, (iii) to effect any reclassification of its Preferred Stock (other than a reclassification involving only the subdivision or combination of outstanding Preferred Stock), (iv) to effect the liquidation, dissolution or winding up of the Company, or (v) to declare or pay any dividend on the Common Stock payable in Common Stock, to effect a subdivision, combination or consolidation of the Common Stock (by reclassification or otherwise than by payment of dividends in Common Stock), then, in each such case, the Company shall give to each holder of a Right Certificate, in accordance with Section 25 hereof, a notice of such proposed action, which shall specify the record date for the purposes of such stock dividend or distribution or offering of rights or warrants, or the date on which such liquidation, dissolution, winding up, reclassification, subdivision, combination or consolidation is to take place and the date of participation therein by the holders of the Common Stock and/or Preferred Stock, if any such date is to be fixed, and such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least 10 days prior to the record date for determining holders of the Preferred Stock for purposes of such action, and in the case of any such other action, at least 10 days prior to the date of the taking of such proposed action or the date of participation therein by the holders of the Common Stock and/or Preferred Stock, whichever shall be the earlier.

          (b)          In case any event described in Section 11(a)(ii) shall occur then the Company shall as soon as practicable thereafter give to each holder of a Right Certificate (or if occurring prior to the Distribution Date, the holders of the Common Stock) in accordance with Section 25 hereof, a notice of the occurrence of such event, which notice shall describe such event and the consequences of such event to holders of Rights under Section 11(a)(ii).

          (c)          The failure to give notice required by this Section 24 or any defect therein shall not affect the validity of the action taken by the Company or the vote upon any such action.

(A)          Each share of Series A Preferred Stock shall entitle the holder thereof to a number of votes equal to the Adjustment Number on all matters submitted to a vote of the stockholders of the Corporation.

(B)          Except as required by law, by Section 3(C) and by Section 10 hereof, holders of Series A Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action.

(A)          Whenever dividends or distributions payable on the Series A Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series A Preferred Stock outstanding shall have been paid in full, the Corporation shall not:

(i)          declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock;

(ii)          declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, except dividends paid ratably on the Series A Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled; or

(iii)          purchase or otherwise acquire for consideration any shares of Series A Preferred Stock, or any shares of stock ranking on a parity with the Series A Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of Series A Preferred Stock, or to such holders and holders of any such shares ranking on a parity therewith, upon such terms as the Board of Directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes.

(B)          The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under paragraph (A) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner.

(A)          Upon any liquidation, dissolution or winding up of the Corporation, voluntary or otherwise, no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock unless, prior thereto, the holders of shares of Series A Preferred Stock shall have received an amount per share (the “Series A Liquidation Preference”) equal to the greater of (i) $1,000 plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment, or (ii) the Adjustment Number times the per share amount of all cash and other property to be distributed in respect of the Common Stock upon such liquidation, dissolution or winding up of the Corporation.

(B)          In the event, however, that there are not sufficient assets available to permit payment in full of the Series A Liquidation Preference and the liquidation preferences of all other classes and series of stock of the Corporation, if any, that rank on a parity with the Series A Preferred Stock in respect thereof, then the assets available for such distribution shall be distributed ratably to the holders of the Series A Preferred Stock and the holders of such parity shares in proportion to their respective liquidation preferences.

(C)          Neither the merger or consolidation of the Corporation into or with another entity nor the merger or consolidation of any other entity into or with the Corporation shall be deemed to be a liquidation, dissolution or winding up of the Corporation within the meaning of this Section 6.
