12. Adjustments and Other Rights. The Exercise Price and Option Shares subject to this Option shall be subject to adjustment from time to time as follows; provided that if more than one subsection of this Section 12 is applicable to a single event, the subsection shall be applied that produces the largest adjustment, no single event shall cause an adjustment under more than one subsection of this Section 12 so as to result in duplication and, for the avoidance of doubt, no increase to the Exercise Price or decrease in the number of Option Shares subject to this Option shall be made pursuant to this Section 12.

(i) Stock Splits, Subdivisions, Reclassifications or Combinations. If the Company shall at any time or from time to time (a) declare, order, pay or make a dividend or make a distribution on its Common Stock in shares of Common Stock, (b) split, subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares or (c) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares, the number of Option Shares subject to this Option at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be proportionately adjusted so that the Optionholder immediately after such record date or effective date, as the case may be, shall be entitled to purchase the number of shares of Common Stock which such holder would have owned or been entitled to receive in respect of the shares of Common Stock subject to this Option after such date had this Option been exercised in full immediately prior to such record date or effective date, as the case may be. In the event of such adjustment, the Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be immediately adjusted to the number obtained by dividing (x) the product of (1) the number of Option Shares subject to this Option in full before the adjustment determined pursuant to the immediately preceding sentence and (2) the Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the dividend, distribution, split, subdivision, combination or reclassification giving rise to such adjustment by (y) the new number of Option Shares subject to this Option in full determined pursuant to the immediately preceding sentence.

-6-

(ii) Distributions. If the Company shall fix a record date for the making of a dividend or other distribution (by spin-off or otherwise) on shares of Common Stock, whether in cash, Equity Interests of the Company, other securities of the Company, evidences of indebtedness of the Company or any other Person or any other property (including Equity Interests, other securities or evidences of indebtedness of a subsidiary), or any combination thereof, excluding (x) dividends or distributions subject to adjustment pursuant to Section 12(i) or (y) dividends or distributions of rights in connection with the adoption of a stockholder rights plan in customary form (including with respect to the receipt of such rights in respect of shares of Common Stock issued subsequent to the initial dividend or distribution of such rights), then (a) in the case of any such cash dividend or distribution, the Exercise Price in effect immediately prior to such record date shall be reduced by the gross amount of such cash dividend or distribution without giving effect to any withholding or deduction of taxes at the source by or on behalf of any applicable authority having power to tax in respect of such cash dividend or distribution and (b) in each such other case, in addition to the number of Option Shares subject to this Option, the Optionholder shall be entitled to receive such Equity Interests of the Company, other securities of the Company, evidences of indebtedness of the Company or any other Person or any other property (including Equity Interests, other securities or evidences of indebtedness of a subsidiary), or any combination thereof, that a holder of such number of shares of Common Stock on such record date would have been entitled to receive as a result of such dividend or other distribution. For purposes of the foregoing, in the event that such dividend or distribution in question is ultimately not so made, the Exercise Price and the number of Option Shares subject to this Option then in effect shall be readjusted, effective as of the date when the Board of Directors determines not to make such dividend or distribution, to the Exercise Price that would then be in effect and the number of Option Shares that would then be subject this Option if such record date had not been fixed. The provisions of this Section 12 shall apply in respect of any Equity Interests that the Optionholder may become entitled to receive by operation of this Section 12(ii).

(iii) Merger Event. In case of any Merger Event, notwithstanding anything to the contrary contained herein, (a) the Exercise Price shall be reduced (but not below zero) by the amount of cash, if any, forming part of the merger consideration per share of Common Stock (assuming for this purpose that any election to receive cash in respect of shares of Common Stock is made for the maximum amount of cash that may be delivered) and (b) the Optionholder’s right to receive Option Shares upon exercise of this Option shall be converted, effective upon the occurrence of such Merger Event, into the right to exercise this Option to acquire the number of shares of stock or other securities or property (including cash) that the Common Stock subject to (at the time of such Merger Event) this Option immediately prior to such Merger Event would have been entitled to receive upon consummation of such Merger Event (assuming for this purpose that any election to receive cash in respect of shares of Common Stock is made for the maximum amount of cash that may be delivered).

(iv) Calculation of Certain Option Property. Notwithstanding anything to the contrary, in the event that any Equity Interests, other securities of the Company or any other Person or any other property that the Optionholder may become entitled to receive by operation of this Section 12 (individually and collectively, “Option Property”) shall, by its terms, in whole or in part, (x) mature or expire prior to the Expiration Time, or (y) require the giving of any notice or the taking of any action the failure of either of which could result in (1) the forfeiture of rights or value to which the holder thereof would otherwise be entitled prior to the Expiration Time or (2) the maturation or expiration of such Option Property prior to the Expiration Time, then the Exercise Price shall be reduced by the fair market value of such Option Property determined in accordance with this Section 12(iv). The fair market value of Option Property that is listed or traded on an exchange or the prices for which are available on a quotation system shall be the last sale price for such Option Property on such exchange or quotation system. If such Option Property is not listed or traded an exchange or quotation system, the Grantor shall determine the fair market value of such Option Property based on prices for such Option Property obtained from several leading dealers in the market for such Option Property, or if such prices are not available to the Grantor notwithstanding its commercially reasonable efforts so to procure, the fair market value of such Option Property shall be determined by a nationally recognized investment banking, accounting or valuation firm mutually agreed by the Grantor and the Optionholder.

(v) Statement Regarding Adjustments. Whenever the Exercise Price or the number of Option Shares subject to this Option shall be adjusted as provided in this Section 12, the Grantor shall determine the amount and form of any such adjustment in good faith and in a commercially reasonable manner and shall prepare a statement showing in reasonable detail the basis for such determination (including any quotations, market data or information from internal or external sources, and any assumptions, used in making such determination) and cause a copy of such

-7-

statement to be delivered to the Optionholder as promptly as practicable and in no event later than 5 Business Days following its determination regarding such adjustment.

(vi) Notice of Adjustment Event. In the event that the Company takes any action of the type described in this Section 12 (but only if the action of the type described in this Section 12 would result in an adjustment in the Exercise Price or the number of Option Shares subject to this Option or a change in the type of securities or property to be delivered upon exercise of this Option), the Grantor shall provide written notice to the Optionholder, which notice shall set forth the facts with respect thereto as shall be reasonably necessary to indicate the proposed effect on the Exercise Price and the number, kind or class of shares or other securities or property which upon the delivery of such shares or other securities or property to a holder of Common Stock, is expected to be deliverable to the Optionholder upon exercise of this Option and show in reasonable detail the basis for such determination (including any quotations, market data or information from internal or external sources, and any assumptions, used in making such determination).

(vii) Adjustment Rules. Any adjustments pursuant to this Section 12 shall be made successively whenever an event referred to herein shall occur.
