If the Board of Directors determines the fair market value of any distribution for purposes of this paragraph (,4) by reference to the actual or when issued trading market for any securities comprising such distribution, it must in -3- doing so consider the prices in such market over the same period used in computing the current market price per share pursuant to paragraph (8) of this Section 2(b). (5) In case the Company shall, by dividend or otherwise, make a (,ash Distribution, then, and in each such case, immediately after the close of business on the Determination Date for such Cash Distribution, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close of business on such Determination Date by a fraction (a) the numerator of which shall be equal to the current market price per share (determined as provided in paragraph (8) of this Section 2(b)) of the Common Stock on such Determination Date less an, amount equal to the quotient of (1) the amount of such Cash Distribution divided by (2) the number of shares of Common Stock outstanding on such Determination Date and (b) the denominator of which shall be equal to the current market price per share (determined as provided by paragraph (8) of this Section 2(b)) of the Common Stock on such Determination Date. (6) In case the Company or any Subsidiary shall make an Excess Purchase Payment, then, and in each such case, immediately prior to the opening of business on the day after the tender offer in respect of which such Excess Purchase Payment is to be made expires, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by dividing the Conversion Rate in effect immediately prior to the close of business on the Determination Date for such tender offer by a fraction (a) the numerator of which shall be equal to the product of (A) the number of shares of Common Stock outstanding (including any tendered shares) at such Determination Date less (B) the amount of such Excess Purchase Payment and (b) the denominator of which shall be equal to the product of (X) the current market price per share of the Common Stock (determined as provided in paragraph (8) of this Section 2(b) as of such Determination Date multiplied by (Y) the number of shares of Common Stock outstanding (including any tendered shares) as of the Determination Date less the number of all shares validly tendered and not withdrawn as of the Determination Date. (7) The reclassification of Common Stock into securities other than Common Stock (other than any reclassification upon a consolidation or merger to which Section 2(h) applies) shall be deemed to involve (a) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be the Determination Date), and (b) a subdivision or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day upon which such subdivision becomes effective" or "the day upon which such combination becomes effective", as the case may be, and "the day upon which such subdivision or combination becomes effective" within the meaning of paragraph (3) of this Section 2(b)). Rights or warrants issued by the Company to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of Common Stock, which rights or warrants (i) are deemed to be transferred with such shares of Common Stock, (ii) are not exercisable and (iii) are :also issued in respect of future issuances of Common Stock, in each case in clauses (i) through (iii) until the occurrence of a specified event or events ("Trigger Event"), shall for purposes of this Section 2(b) not be deemed issued until the occurrence of the earliest Trigger Event. -4- (8) For the purpose of any computation under paragraphs (2), (4), (5) or (6) of this Section 2(b) the current market price per share of Common Stock on any date shall be calculated by the Company and be deemed to be the average of the daily Closing Prices for the five consecutive Trading Days selected by the Company commencing not more than 10 Trading Days before, and ending not later than, the earlier of the day in question and the day before the "ex" date with respect to the issuance or distribution requiring such computation. For purposes of this paragraph, the term "ex" date, when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way in the applicable securities market or on the applicable securities exchange without the right to receive such issuance or distribution. (9) No adjustment in the Conversion Rate shill be required unless such adjustment (plus any adjustments not previously made by reason of this paragraph (9)) would require an increase or decrease of at least one percent in such rate; PROVIDED, HOWEVER, that any adjustments which by reason of this paragraph (9) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 2 shall be made to the nearest cent or to the nearest hundredth of a share, as the case may be. (10) The Company may make such increases in the Conversion Rate, for the remaining term of the Securities or any shorter term in addition to those required by paragraph (10, (2), (3), (4), (5) and (6) of this Section 2(b) as it considers to be advisable in order to avoid or diminish any income tax to any holders of shares of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes. (11) In addition to the foregoing adjustments, as of the opening of business on the reset Date, the Conversion Rate will be adjusted to equal $1,000 divided by the product of 1.20 and the average Closing Price of the Common Stock for the immediately preceding five Trading Days, provided that such Conversion Rate computed pursuant to this paragraph (11) shall not be less than 52.4109 nor exceed 78.6164. The adjustment required pursuant to this paragraph (11) will not be subject to the limitation set forth in paragraph (9) of this Section 2(b).

(b) INDEMNIFICATION BY THE PURCHASER AND ANY AGENTS AND UNDERWRITER. The Company may require, as a condition to including, any Shares in any registration statement filed pursuant to Section 2 hereof and to entering into any underwriting agreement with respect thereto, that the Company shall have received an undertaking reasonably satisfactory to it from the Purchaser and from each underwriter named in any such underwriting agreement, severally and not jointly, to (i) indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof arise out of or are based upon an untrue statement or alleged untrue statement of material fact contained in such registration statement, or any preliminary, final or summary prospectus contained therein or furnished by the Company to the Purchaser, agent or underwriter, or any amendment or Supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with information furnished to the Company by the Purchaser or underwriter expressly for use therein, and (ii) reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. (c) NOTICES OF CLAIMS, ETC. Promptly after receipt by an indemnified party under subsection (a) or (b) above of written notice of the commencement of any action, such indemnified party shall, if claim in respect thereof is to be made against an indemnifying party pursuant to the indemnification provisions of or contemplated by this Section 6, notify such indemnifying party in writing of the commencement of such action; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party other than under the indemnification provisions of or contemplated by Section 6(a) or 6(b) hereof. In case any such action shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any -8- other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. (d) CONTRIBUTION. Each party hereto agrees that, if for any reason the indemnification provisions contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by indemnified party on the one hand and the indemnifying party on the other from any offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Purchaser on the other shall be deemed to be in the same proportion as the total purchase price received by the Company upon issuance of the Convertible Note bears to the difference between the proceeds from the offering of the Shares received by the Purchaser and such purchase price. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were determined by pro rata allocation (even if the Purchaser or any agents or underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, or liabilities (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), the Purchaser shall not be required to contribute any amount in excess of the amount by the Purchaser from the sale of any Shares (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount of any damages which the Purchaser have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such underwriter has otherwise been required to pay by reason or such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Purchaser's and any underwriters' obligations in this Section 6(d) to contribute shall be several in proportion to the principal amount of Shares registered or underwritten, as the case may be, by them and not joint. (e) The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and partner of the Purchaser, any agent and any underwriter and each person, if any, who controls the Purchaser or any agent or underwriter within the meaning of the Securities Act; and the obligations of the Purchaser and any agent and underwriters contemplated by this Section 6 shall be in addition to any -9- liability which the Purchaser or any such agent or underwriter, respectively, may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company (including any person who, with his consent, is named in arty registration statement as about to become a director of the Company) and to each person, if any, who controls the Company within the meaning of the Securities Act. 7. MISCELLANEOUS. (a) NO INCONSISTENT AGREEMENTS.
