(b) Restrictive Legend. Each certificate representing (i) this ------------------ Warrant, (ii) the shares of Common Stock issued upon exercise of the Warrant and (iii) any other securities issued in respect of such shares of Common Stock upon any stock split, stock dividend or similar event (collectively, the "Restricted Securities"), shall (unless otherwise permitted by the provisions of Section 4(c) below or unless such securities have been registered under the Securities Act) be imprinted with the following legend, in addition to any legend required under applicable state securities laws: 2 THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR APPLICABLE BLUE SKY LAWS, AND ARE SUBJECT TO CERTAIN INVESTMENT REPRESENTATIONS.

Upon request of a holder of a certificate with such legend imprinted thereon, the Company shall remove the foregoing legend therefrom or, if appropriate, issue to such holder a new certificate therefor free of any transfer legend, if, with such request, the Company shall have received either the opinion referred to in Section 4(c)(i) or the "no-action" letter referred to in Section 4(c)(ii) to the effect that any transfer by such holder of the securities evidenced by such certificate will be exempt from the registration and/or qualification requirements of, and that such legend is not required in order to establish compliance, with the Securities Act, and if applicable, any state securities laws under which transfer restrictions on such securities had been previously imposed. (c) Notice of Proposed Transfers.

The number and kind of securities purchasable upon the exercise of this Warrant and 3 the Warrant Price shall be subject to adjustment from time to time upon the happening of certain events, as follows: (a) Consolidation, Merger, Reorganization, Etc. If the Company at any ------------------------------------------- time while this Warrant remains outstanding and unexpired shall consolidate with or merge into any other corporation, reorganize, reclassify, or in any manner change the securities then purchasable upon the exercise of this Warrant, then upon consummation thereof this Warrant shall thereafter represent the right of Warrantholder to receive, to the extent this Warrant is exercisable as provided above in Section 1, in lieu of shares of Common Stock, the cash or such number of securities to which Warrantholder would have been entitled upon consummation thereof if Warrantholder had exercised this Warrant immediately prior thereto.

If the Company at any time shall subdivide or combine its - --------------- Common Stock, or take a record of the holders of its Common Stock for the purpose of entitling them to receive without payment a dividend payable in, or other distribution of, Common Stock or other securities, then the number of shares of Common Stock purchasable hereunder shall be adjusted to that number determined by multiplying the number of shares purchasable upon the exercise of this Warrant immediately prior to such adjustment by a fraction (i) the numerator of which shall be the total number of shares of Common Stock outstanding immediately after such subdivision, combination, dividend or distribution, and (ii) the denominator of which shall be the total number of shares of Common Stock outstanding immediately prior to such subdivision, combination, dividend or distribution. Additionally, the Warrant Price shall be adjusted to that price determined by multiplying the Warrant Price in effect immediately prior to such subdivision, combination, dividend or distribution by a fraction (x) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such subdivision, combination, dividend or distribution, and (y) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such subdivision, combination, dividend or distribution.

Capitalized terms used in this paragraph shall, unless otherwise specifically defined in this Warrant, have the meanings ascribed to them in the Certificate of Determination. If, after the issuance of this Warrant, the Company shall at 4 any time or from time to time issue (or be deemed under Section 5 of the resolutions set forth in the Certificate of Determination to have issued) any Additional Shares of Common Stock (excluding the Series G Preferred Stock issued pursuant to the Stock Purchase Agreement) at a price less than the Warrant Price and such issuance or deemed issuance would result in an adjustment to the Conversion Price of the Series G Preferred Stock, pursuant to Sections 5(g) or 5(h) of the Certificate of Determination, assuming hypothetically solely for purposes of this paragraph that the initial Conversion Price of the Series G Preferred Stock is $8.00 (which the parties acknowledge is not the case), the Warrant Price shall forthwith be adjusted (in each case of any such issuance or deemed issuance) to the adjusted Conversion Price which would have been applicable to the Series G Preferred Stock under such Sections 5(g) or 5(h) by reason of such issuance or deemed issuance if the Conversion Price of the Series G Preferred Stock had been initially $8.00. (d) Statement Regarding Adjustments. When any adjustment is required ------------------------------- to be made in the Warrant Price, either initially or as further adjusted hereunder, the Company shall forthwith determine the adjusted number of shares of Common Stock purchasable hereunder and the new Warrant Price and shall (i) prepare and retain on file a statement describing in reasonable detail the method used in arriving at the adjusted number of shares of Common Stock purchasable hereunder and the new Warrant Price; and (ii) cause a copy of such statement to be mailed to Warrantholder as of a date within ten (10) days after the date when the circumstances giving rise to the adjustment occurred. 6. Fractional Shares. No fractional shares of Common Stock will be ----------------- issued in connection with any exercise hereunder but in lieu of such fractional shares, the Company shall make a cash payment therefor upon the basis of the fair market value of the Common Stock on the date of such exercise. 7. Registration Rights. The Warrant Shares shall have registration ------------------- rights provided for in the Stock Purchase Agreement. 8. Governing Law.
