Any such new Warrant executed and delivered shall constitute an additional obligation of the Company, -4- whether or not this Warrant, reportedly lost, stolen, destroyed or mutilated, shall be at any time presented by anyone to the Company for exercise. 7. ADJUSTMENT OF EXERCISE PRICE 7.1 General If any of the following events shall occur at any time or from time to time prior to the exercise in full or expiration of this Warrant, the following adjustments shall be made in the Exercise Price, with the exceptions hereinafter provided: (a) Recapitalization In case the Company effects a subdivision, combination, reclassification or other recapitalization of its outstanding shares of Series I Stock into a greater or lesser number of shares of Series I Stock, the Exercise Price in effect immediately after such subdivision, combination, reclassification or other recapitalization shall be proportionately decreased or increased, as the case may be. (b) Stock Dividends If the Company shall declare a dividend on its Series I Stock payable in stock or other securities of the Company or of any other corporation to the holders of its Series I Stock, the Holder shall, without additional cost, be entitled to receive upon the exercise of this Warrant, in addition to the Warrant Shares to which such Holder is otherwise entitled upon such exercise, the number of shares of stock, or other securities that such Holder would have been entitled to receive if such Holder had been a holder, on the record date for such dividend, of the number of shares of Series I Stock so purchased under this Warrant. (c) Merger or Consolidation-No Change in Control In case of any merger, consolidation or reorganization of the Company with or into one or more corporations that results in holders of the Company's voting equity securities immediately prior to such event together owning a majority interest of the voting equity securities of the surviving corporation immediately following such event, the Holder, upon the exercise of this Warrant after the record date for determination of shareholders entitled thereto, shall receive, in lieu of or in addition to any shares of Series I Stock, the proportionate share of all stock or other securities (appropriately adjusted for any subsequent events of the issuer of such stock or securities that are of the kind that would cause adjustment of the Exercise Price hereunder) or other property issued, paid or delivered for or on all the Series I Stock -5- as would have been allocable to the Warrant Shares so purchased under this Warrant had this Warrant been exercised immediately prior to said record date. (d) Merger or Consolidation--Change in Control In case of any merger, consolidation or reorganization of the Company with or into one or more other corporations, that results in the holders of the Company's voting equity securities immediately prior to such event together owning less than a majority interest of the voting securities of the surviving corporation immediately following such event, or in case of any sale, lease, transfer or conveyance to another corporation of all or substantially all the assets of the Company or proposed liquidation of the Company, then in any such event the Holder shall be given notice of such proposed action at approximately the same time and in substantially the same manner as the holders of the Series I Stock. The Holder may attend the meeting of the Company's shareholders at which such action is considered and voted upon. If the proposed action is approved according to applicable law by the shareholders of all corporations or other entities that are parties to the proposed action, the Holder shall be so notified in writing by the Company by registered or certified mail at least 10 days before the effectiveness thereof. Notwithstanding the period of exercisability stated on the face of this Warrant, this Warrant shall become forever null and void to the extent not exercised on or before 5:00 p.m., Pacific time, on the tenth business day following the delivery of such notice. (e) Minimum Adjustment Not Required Anything in this Section 7.1 to the contrary notwithstanding, the Company shall not be required, except as hereinafter provided, to make any adjustment of the Exercise Price in any case in which the amount by which such Exercise Price would be increased or reduced, in accordance with the foregoing provisions, which would be less than $.001, but in such a case, any adjustment that would otherwise be required to be made will be carried forward and made at the time and together with the next subsequent adjustment that, together with any and all such adjustments so carried forward, shall amount to not less than $.001; provided, however, that adjustments in the Exercise Price shall be required and made in accordance with the provisions of this Section 7.1 (other than this Section 7.1(e)) not later than such time as may be required in order to preserve the tax-free nature of any distribution (within the meaning of Section 305 of the United States Internal Revenue Code of 1986, as amended) to the Holder or the holders of Series I Stock. In the event of any subdivision, combination, reclassification or other recapitalization of shares of Series I Stock, said amount (as theretofore decreased or increased) shall be proportionately decreased or increased. -6- 7.2 Number of Warrant Shares Adjusted After any adjustment of the Exercise Price pursuant to Section 7.1 hereof, the number of Warrant Shares issuable at the new Exercise Price shall be adjusted to the number obtained by (i) multiplying the number of Warrant Shares issuable upon exercise of this Warrant immediately before such adjustment by the Exercise Price in effect immediately before such adjustment and (ii) dividing the product so obtained by the new Exercise Price. 7.3 Notice of Adjustment Whenever events occur requiring the Exercise Price to be adjusted, the Company shall promptly file with its Secretary or an Assistant Secretary at its principal office and with its stock transfer agent, if any, a certificate of its chief financial officer showing the adjusted Exercise Price, setting forth in reasonable detail the acts requiring such adjustment, and stating such other facts as shall be necessary to show the manner and figures used to compute such adjustment. Such chief financial officer's certificate shall be made available at all reasonable times for inspection by the Holder. Promptly after each such adjustment, the Company shall mail a copy of such certificate by certified mail to the Holder. The Company shall endorse on any Warrant executed and delivered by the Company a description of each adjustment, if any, under this Section 7 as the result of events occurring before the execution and delivery of the Warrant. If, within 45 days of the mailing of such certificate, the Holder notifies the Company in writing of the Holder's good-faith disagreement with the adjusted Exercise Price contained in the Company certificate, then the Company will promptly obtain a certificate of a firm of independent certified public accountants of recognized standing selected by the Company's Board of Directors (who may be the regular auditors of the Company) covering the same items required by the Company certificate. The Company will promptly mail a copy of the accountants' certificate to the Holder of this Warrant. The certificate of the firm of independent public accountants will be conclusive evidence of the correctness of the computations with respect to any adjustment of the Exercise Price. 8. NOTICES TO HOLDER So long as this Warrant is outstanding, whenever the Company shall expect to (i) pay any dividend or distribution upon the Series I Stock, (ii) effect any recapitalization, merger, consolidation, reorganization, transfer, sale, lease or conveyance as referred to in Section 7 hereof, or (iii) be involved in any voluntary or involuntary dissolution, liquidation or winding up of the Company, at least 10 days -7- before the proposed action or any applicable record date, the Company shall give the Holder written notice describing the proposed action and stating the date on which (x) a record date is to be fixed for the purpose of such dividend, distribution or right or (y) such recapitalization, merger, consolidation, reorganization, transfer, sale, lease, conveyance, dissolution, liquidation or winding up is to take place and when, if any date is to be fixed, the record holders of Series I Stock shall be entitled to exchange their shares of Series I Stock for securities or other property deliverable upon such recapitalization, merger, consolidation, reorganization, transfer, sale, lease, conveyance, dissolution, liquidation or winding up. 9.
