ADJUSTMENT OF EXERCISE PRICE. (a) Common Stock Dividends; Common Stock Splits; Reverse Common Stock Splits. If the Company, at any time while this Warrant is outstanding, (a) shall pay a stock dividend on its Common Stock, (b) subdivide outstanding shares of Common Stock into a larger number of shares, (c) combine outstanding shares of Common Stock into a smaller number of shares, or (d) issue by reclassification of shares of Common Stock any shares of capital stock of the Company, the Exercise Price shall be multiplied by a fraction the numerator of which shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and the denominator of which shall be the number of shares of Common Stock outstanding after such event. Any adjustment made pursuant to this paragraph (6)(a) shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification. (b) Rights; Options; Warrants. If the Company, during the period commencing on the Closing Date (as defined in the Purchase Agreement) through and including the date which is 12 months from the Issue Date, shall issue rights or warrants to all of the holders of Common Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share less than $26.95, the Exercise Price shall be multiplied by a fraction, the denominator of which shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and the numerator of which shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding on the date of issuance of such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at $26.95 per share. Such adjustment shall be made whenever such rights or warrants are issued, and shall become effective immediately after the record date for the determination of shareholders entitled to receive such rights or warrants. However, upon the expiration of any right or warrant to purchase Common Stock the issuance of which resulted in an adjustment in the Exercise Price pursuant to this paragraph (6)(b), if any such right or warrant shall expire and all or any portion thereof shall not have been exercised, the Exercise Price shall immediately upon such expiration be re-computed and effective immediately upon such expiration be increased to the price which it would have been (but reflecting any other adjustments in the Exercise Price made pursuant to the provisions of Section 6(g) after the issuance of such rights or warrants) had the adjustment of the Exercise Price made upon the issuance of such rights or warrants been made on the basis of offering for subscription or purchase only that number of shares of 3 4 Common Stock (if any) actually purchased upon the exercise of such rights or warrants actually exercised; provided, however, that if (X) (1) the Registration Statement (as defined in the Registration Rights Agreement) is then in effect and has been in effect and sales of all of the Registrable Securities (as defined in the Registration Rights Agreement) can be made thereunder for at least twenty (20) Trading Days prior to a Trigger Date (as defined below); (2) the Company has, at all times prior to the Trigger Date, a sufficient number of authorized shares of Common Stock reserved for issuance upon full conversion of all of the Securities (as defined in the Purchase Agreement) issued pursuant to the Purchase Agreement; and (3) no Event of Default shall have occurred and be continuing on the Trigger Date or at any time during the twenty (20) Trading Days prior to a Trigger Date; and (Y) the Per Share Market Value is greater than 150% of the Conversion Price (as defined in the debentures issued pursuant to the Purchase Agreement (the "Debentures")) in effect on the Closing Date (as defined in the Purchase Agreement) for any five (5) consecutive Trading Days prior to the 180th day following the Issue Date (the last day of such five (5) consecutive Trading Day period being referred to herein as the "Trigger Date"), then this provision shall expire automatically on the 180th day following the Issue Date. (c) Subscription Rights. If the Company, during the period commencing on the Closing Date (as defined in the Purchase Agreement) through and including the date which is 12 months from the Issue Date, shall distribute to all of the holders of Common Stock evidences of its indebtedness or assets or rights or warrants to subscribe for or purchase any security (excluding those referred to in paragraphs 6(a) and (b) above), then in each such case the Exercise Price at which the Warrant shall thereafter be exercisable shall be determined by multiplying the Exercise Price in effect immediately prior to the record date fixed for determination of shareholders entitled to receive such distribution by a fraction the denominator of which shall be the Per Share Market Value of Common Stock determined as of the record date mentioned above, and the numerator of which shall be such Per Share Market Value of the Common Stock on such record date less the then fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of Common Stock as determined by the Board of Directors in good faith; provided, however, that in the event of a distribution exceeding ten percent (10%) of the net assets of the Company, such fair market value shall be determined by a nationally recognized or major regional investment banking firm or firm of independent certified public accountants of recognized standing (an "Appraiser") selected in good faith by the Registered Owner of the Warrant; and provided, further, that the Company, after receipt of the determination by such Appraiser shall have the right to select an additional Appraiser meeting the same qualifications, in good faith, in which case the fair market value shall be equal to the average of the determinations by each such Appraiser. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above; provided, however, that if (X) (1) the Registration Statement (as defined in the Registration Rights Agreement) is then in effect and has been in effect and sales of all of the Registrable Securities (as defined in the Registration Rights Agreement) can be made thereunder for at least twenty (20) Trading Days prior to a Trigger Date; (2) the Company has, at all times prior to the Trigger Date, a sufficient number of authorized shares of Common Stock reserved for issuance upon full conversion of all of the Securities (as defined in the Purchase Agreement) issued pursuant to the Purchase Agreement; and (3) no Event of Default shall have occurred and be continuing on the Trigger Date or at any time during the twenty (20) Trading Days prior to a Trigger Date; and (Y) the Per Share Market Value is greater than 150% of the Conversion Price (as defined in the Debentures) in effect on the Closing Date (as defined in the 4 5 Purchase Agreement) for any five (5) consecutive Trading Days prior to the 180th day following the Issue Date, then this provision shall expire automatically on the 180th day following the Issue Date. (d) Rounding. All calculations under this section 6 shall be made to the nearest cent or the nearest l/l00th of a share, as the case may be. (e) Notice of Adjustment. Whenever the Exercise Price is adjusted pursuant to paragraphs 6(a), (b), (c) or (h), the Company shall promptly mail to the holder of the Warrant, a notice setting forth the Exercise Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Upon each adjustment of the Exercise Price pursuant paragraphs 6(a), (b), (c) or (h), the number of shares of Common Stock issuable upon exercise of this Warrant shall be adjusted by multiplying a number equal to the Exercise Price in effect immediately prior to such adjustment by the number of shares of Common Stock issuable upon exercise of this Warrant immediately prior to such adjustment and dividing the product so obtained by the adjusted Exercise Price. (f) Redemption Events. In case of (A) any reclassification of the Common Stock, (B) any consolidation or merger of the Company with or into another person pursuant to which (i) a majority of the Company's Board of Directors will not constitute a majority of the board of directors of the surviving entity or (ii) less than 51% of the outstanding shares of the capital stock of the surviving entity will be held by the same shareholders of the Company prior to such reclassification, consolidation or merger, (C) the sale or transfer of all or substantially all of the assets of the Company, (D) any compulsory share exchange pursuant to which the Common Stock is converted into other securities, cash or property, (E) suspension from listing or delisting of the Common Stock from the National Market System of the Nasdaq Stock Market ("Nasdaq") or any other exchange on which the Common Stock is listed for a period of five (5) consecutive Trading Days, (F) the Company's notice to any Registered Owner, including by way of public announcement, at any time, of its intention, for any reason, not to comply with proper requests for the exercise of any such warrants, or (G) a breach by the Company of any representation, warranty, covenant or other term or condition of the Purchase Agreement, the Registration Rights Agreement or any other agreement, document, certificate or other instrument delivered in connection with the transactions contemplated thereby or hereby, except to the extent that such breach would not have a Material Adverse Effect (as defined in Section 3(a) of the Purchase Agreement) and except, in the case of a breach of a covenant which is curable, only if such breach continues for a period of at least ten (10) days after the Company knows or reasonably should have known of the existence of such breach (clauses (A) through (G) above referred to as a "Redemption Event"), the holder of the Warrant shall have the right thereafter to exercise the Warrant within ten (10) Business Days of the Redemption Event for the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of Common Stock following such Redemption Event, and the holder of the Warrant shall be entitled upon such event to receive such amount of securities, cash or property as the shares of the Common Stock of the Company into which the Warrant could have been converted immediately prior to such Redemption Event would have been entitled. 5 6 (g) Reclassification, Etc.

If the Company, during the period commencing on the Closing Date (as defined in the Purchase Agreement) through and including the date which is 12 months from the Issue Date, takes any of the actions described in this Section 6(h), then, in order to prevent dilution of the rights granted under this Warrant, the Exercise Price will be subject to adjustment from time to time as provided in this Section 6(h); provided, however, that if (X) (1) the Registration Statement (as 6 7 defined in the Registration Rights Agreement) is then in effect and has been in effect and sales of all of the Registrable Securities (as defined in the Registration Rights Agreement) can be made thereunder for at least twenty (20) Trading Days prior to a Trigger Date; (2) the Company has, at all times prior to the Trigger Date, a sufficient number of authorized shares of Common Stock reserved for issuance upon full conversion of all of the Securities (as defined in the Purchase Agreement) issued pursuant to the Purchase Agreement; and (3) no Event of Default shall have occurred and be continuing on the Trigger Date or at any time during the twenty (20) Trading Days prior to a Trigger Date; and (Y) the Per Share Market Value is greater than 150% of the Conversion Price (as defined in the Debentures) in effect on the Closing Date (as defined in the Purchase Agreement) for any five (5) consecutive Trading Days prior to the 180th day following the Issue Date, then this provision shall expire automatically on the 180th day following the Issue Date: (i) Adjustment of Exercise Price upon Issuance of Common Stock.

A "Strategic Venture" shall mean a venture between the Company and a pharmaceutical or biotechnology company or an Affiliate thereof, the primary purpose of which is not to raise capital in the form of equity (including without limitation through the issuance of warrants, convertible securities, phantom stock rights, stock appreciation rights or other rights with equity features) and pursuant to which the Company contributes or issues securities of the Company valued at less than 50% of the entire contribution of the Company.

No adjustment of the Exercise Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities. B. Issuance of Convertible Securities. If, during the period commencing on the Closing Date (as defined in the Purchase Agreement) through and including the date which is 12 months from the Issue Date, the Company in any manner issues or sells any Convertible Securities and the price per share (the "New Convertible Price") for which Common Stock is issuable upon such conversion or exchange (other than the Debenture Shares or Warrant Shares or shares of Common Stock deemed to have been issued by the Company in connection with a Stock Plan, shares of Common Stock issuable upon the exercise of any options or warrants outstanding on the date hereof or upon conversion of convertible securities outstanding on the date hereof, in each case as listed in Schedule 2.1(c) of the Purchase Agreement, shares of Common Stock issued or deemed to have been issued as consideration for an acquisition by the Company of a division, assets or business (or stock constituting any portion thereof) from another person or shares of Common Stock issued or deemed to have been issued in a Strategic Venture) is less than $26.95, then the Exercise Price shall be reduced to equal 120% of the New Convertible Price. C. Change in Option Price or Rate of Conversion. If there is a change during the period commencing on the Closing Date (as defined in the Purchase Agreement) through and including the date which is 12 months from the Issue Date in (i) the purchase price provided for in any Options, (ii) the additional consideration, if any, payable upon the issue, conversion or exchange of any Convertible Securities or (iii) the rate at which any Convertible Securities are convertible into or exchangeable for Common Stock, then the Exercise Price in effect at the time of such change shall be readjusted to the Exercise Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold; provided that no adjustment shall be made if such adjustment would result in an increase of the Exercise Price then in effect. 8 9 D. Certain Definitions. For purposes of determining the adjusted Exercise Price under this Section 6(h)(i), the following terms have meanings set forth below: (I) "Stock Plan" means any stock or compensation plan pursuant to which Common Stock may be issued to any employee, officer, director or consultant of the Company which is either (a) approved by the stockholders of the Company or (b) approved by the compensation committee of the Company's Board of Directors for legitimate compensation purposes which provides for the purchase of the Common Stock at a purchase price of no less than 85% of the market price of the Common Stock on the date of issuance of such option, warrant or security. (II) "Common Stock Deemed Outstanding" means, at any given time, the number of shares of Common Stock issued and outstanding at such time, plus the number of shares of Common Stock deemed to be outstanding pursuant to Sections 6(h)(i)(A) and 6(h)(i)(B) hereof regardless of whether the Options or Convertible Securities are actually exercisable at such time, but excluding any shares of Common Stock issuable upon exercise of the Warrants. E. Effect on Exercise Price of Certain Events. For purposes of determining the adjusted Exercise Price under this Section 6(h)(i), the following shall be applicable: (I) Calculation of Consideration Received. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received by the Company therefor. In case any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the arithmetic average of the Per Share Market Values of such security for the five (5) consecutive Trading Days immediately preceding the date of receipt. In case any Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the Registered Owners of a majority of the Warrant Shares then outstanding. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the "Valuation Event"), the fair value of such consideration will be determined within forty-eight (48) hours of the tenth (10th) day following the Valuation Event by an Appraiser selected by the Company. The determination of such Appraiser shall be binding upon all parties absent manifest error. (II) Integrated Transactions. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for an aggregate consideration of $.001. 9 10 (III) Treasury Shares. The number of shares of Common stock outstanding at any given time does not include shares owned or held by or for the account of the Company, and the disposition of any shares so owned or held will be considered an issue or sale of Common Stock. (IV) Record Date. If the Company takes a record of the holders of Common Stock for the purpose of entitling them (1) to receive a dividend or other distribution payable in Common Stock, Options or in Convertible Securities or (2) to subscribe for or purchase Common stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. (V) Certain Events. If any event occurs of the type contemplated by the provisions of Section 6(h)(i)(subject to the exceptions stated therein) but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company's Board of Directors will make an appropriate adjustment in the Exercise Price so as to protect the rights of the Registered Owner, or assigns, of this Warrant; provided, however, that no such adjustment will increase the Exercise Price as otherwise determined pursuant to this Section 6(h). In no event shall any provision in this Section 6 cause the Exercise Price to be greater than the Exercise Price on the date of issuance of this Warrant. 7. RESTRICTION ON EXERCISE BY THE REGISTERED OWNER. Notwithstanding anything in this Warrant to the contrary, in no event shall the Holder of this Warrant be entitled to exercise a number of Warrants (or portions thereof) in excess of the number of Warrants (or portions thereof) upon exercise of which the sum of (i) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unexercised Warrants and the unexercised or unconverted portion of any other securities of the Company (including the Debentures) subject to a limitation on conversion or exercise analogous to the limitation contained herein) and (ii) the number of shares of Common Stock issuable upon exercise of the Warrants (or portions thereof) with respect to which the determination described herein is being made, would result in beneficial ownership by the Holder and its affiliates of more than 9.9% of the outstanding shares of Common Stock. For purposes of the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13D-G thereunder, except as otherwise provided in clause (i) hereof. Notwithstanding anything in this Warrant to the contrary, the restriction on Holder set forth in this paragraph shall not be amended without (i) the written consent of the Holder and the Company and (ii) the approval of the holders of a majority of the Company's Common Stock present, or represented by proxy, and voting at any meeting called to vote on the amendment of such restriction. 10 11 8.
