Within a reasonable time but no more than twenty (20) days after exercise, certificates for the shares of Common Stock comprising such Shares shall be delivered to the Holder and, unless this Warrant has expired, a Related Warrant representing the number of Shares, if any, with respect to which this Warrant shall not have been exercised shall be issued to the Holder. 2.4 Taxes.

Upon receipt by the Company of satisfactory evidence of the loss, theft, destruction or mutilation of this Warrant and either (in the case of loss, theft or destruction) reasonable indemnification or (in the case of mutilation) the surrender of this Warrant for cancellation, the Company will execute and deliver to the Holder, without charge, a new Warrant of like denomination. Any such new Warrant executed and delivered shall constitute an additional obligation of the Company, whether or not this Warrant, reportedly lost, stolen, destroyed or mutilated, shall be at any time enforceable by anyone. SECTION 7 ANTI-DILUTION ADJUSTMENT OF NUMBER OF SHARES AND EXERCISE PRICE 7.1 Adjustment of Exercise Price. 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 exception hereinafter provided: (a) Recapitalization. In case the Company effects a subdivision, combination, reclassification or other recapitalization of its outstanding shares of Common Stock into a greater or lesser number of shares of Common 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) Dividend Other Than in Cash. If the Company shall declare a dividend on its Common Stock payable in stock or other securities of the Company or of any other corporation, or in property or otherwise than in cash, or the functional equivalent thereof, to the holders of its Common Stock, the Holder shall, without additional cost, be entitled to receive upon the exercise of this Warrant, in addition to the Shares to which such Holder is otherwise entitled upon such exercise, the number of shares of stock or other securities or property which 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 Common 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 which results in holders of the Company's Common Stock immediately prior to such event owning a majority of the voting securities of the surviving corporation immediately following such event, and as a result of which holders of the Company's Common Stock receive other stock, securities or property in lieu of or in addition to, but on account of, their Common Stock, the Holder, upon the exercise of this Warrant after the record date for determination of shareholders -4- 5 entitled thereto, shall receive, in lieu of or in addition to the Shares, the proportionate shares of all stock, or other securities (appropriately adjusted for any subsequent events of the issuer of such stock or securities which are of the kind which would cause adjustment of the Exercise Price hereunder) or other property issued, paid or delivered for or on all of the Common Stock of the Company as would have been allowable to the Shares so purchased under this Warrant had this Warrant been exercised immediately prior to said record date. (d) Merger of Consolidation - Change in Control. In case of any merger, consolidation or reorganization of the Company with or into one or more other corporations, which results in the holders of the Company's Common Stock immediately prior to such event owning less than a majority interest of the voting securities of the surviving corporation immediately following such event, or in the 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 either 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 Company's Common 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 which are parties to the proposed action, the Holder shall be so notified in writing by the Company by registered or certified mail, and thereupon, notwithstanding the period of exercisability stated on the face of this Warrant, this Warrant shall automatically become immediately exercisable and become forever null and void to the extent not exercised on or before 5:00 P.M., California time, on the tenth (10th) 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, would be less than $.05, but in such a case, such adjustment shall be carried forward and when such adjustment, together with any and all such other adjustments so carried forward, shall amount to not less than $.10 the Exercise Price shall be adjusted; provided, however, that adjustments of less than $.05 in the Exercise Price shall be required and made in accordance with the provisions of this Section 7.1 (other than this subparagraph) 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 Common Stock. In the event of any subdivisions, combination, reclassification or other recapitalization of shares of Common Stock, said amount (as theretofore decreased or increased) shall be proportionately decreased or increased. (f) Other Adjustments. The Company, by action of its Board of Directors, shall make such other equitable adjustments to the Exercise Price as may be necessary to protect the Holder against dilution of this Warrant, with or without a request of a Holder, where such an adjustment is appropriate in light of the occurrence of an event or the existence of circumstances similar to those otherwise contemplated by this Section 7.1. -5- 6 (g) Term "Common Stock." Whenever reference is made in Sections 7.1(a) through (e) above to Common Stock, the term "Common Stock" shall include any stock of any class of the Company, other than preferred stock with a fixed limit on dividends, with no rights of conversion into "Common Stock" and with a fixed amount payable in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company. 7.2 Number of Shares Adjusted. After any adjustment of the Exercise Price pursuant to Section 7.1, the number of Shares issuable at the new Exercise Price shall be adjusted to the number obtained by (i) multiplying the number of 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 facts requiring such adjustment, and stating such other facts as shall be necessary to show the manner and figures used to compute such adjustments. Such chief financial officers 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 together with information relating to the adjustment under Section 7.2. The Company shall endorse on any Warrant executed and delivered by the Company a description of each adjustment, if any, under this Section as the result of events occurring before the execution and delivery of the Warrant, and the Warrant so issued shall reflect the number of Shares issuable on exercise, as adjusted to reflect such charges. If, within forty-five (45) days of the mailing of such certificate, Holders holding in the aggregate not less than 25% of the Warrants notify the Company in writing of their disagreements 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 shall not be the regular auditors of the Company) certifying the same items required by the Company certificate or making such adjustments as are appropriate. The Company will promptly mail a copy of the firm of independent public accountants' certificate to the Holder of the this Warrant. Under the circumstances described in this paragraph, the Holders of the Warrants giving notice shall be obligated to reimburse the Company for half of the charges imposed by the independent certified accountants if their certificate confirms the Company's prior calculations. SECTION 8 NOTICE TO HOLDER So long as this Warrant is outstanding, whenever the Company shall expect to (i) pay any dividend or distribution upon Common Stock, (ii) offer to the holders of Common Stock any right to subscribe for or to purchase any other securities of the Company, (iii) effect any recapitalization, merger, consolidation, reorganization, transfer, sale, lease or conveyance as -6- 7 referred to in Section 7, or (iv) be involved in any voluntary or involuntary dissolution, liquidation or winding up of the Company, at least twenty-one (21) days before the proposed action or any applicable record date, the Company, by certified mail, 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 purposes of such dividend, distribution or rights 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 Common Stock shall be entitled to exchange the shares of Common Stock for securities or other property deliverable upon such recapitalization, merger, consolidation, reorganization, transfer, sale, lease, conveyance, dissolution, liquidation or winding up. SECTION 9 REGISTRATION OF THE SHARES 9.1 Registration Rights. (a) Piggy-back Registration. The Company shall advise each Holder of Registrable Securities by written notice at least five days prior to the filing of any Registration Statement pertaining to securities to be offered to the public solely for cash, and will, upon the request of any such Holders, and without any charge to them, include in any such Registration Statement such information as may be required to permit a public offering of their Registrable Securities. If any such Registration Statement or notification is being filed by the Company in connection with an underwritten public offering of securities of the Company, the Company shall have the right to require such Holders (provided that Rule 415 applies to the sale of the Registrable Securities) to postpone the offering of their securities for a period of ninety (90) days following the effective date of such Registration Statement or notification. If any such Registration Statement or notification is being filed by the Company solely for the benefit of selling security holders, the Company will permit such Holders of the Registrable Securities to include for sale with such shareholders in such Registration Statement or notification at least a pro rata portion (based upon the ratio of the number of shares of Common Stock which such selling security holders desire to sell to the number of Registrable Securities which such Holders of the Registrable Securities desire to sell) of the total Registrable Securities being registered, and the offering of the balance of the Registrable Securities owned by holders of the Registrable Securities may then be postponed by the Company for a period of ninety (90) days following effectiveness of the Registration Statement or notification. (b) General Provisions. The following provisions shall also be applicable to any such Registration: (i) The Holders whose Registrable Securities are to be included therein (the "Sellers") shall furnish the Company with such appropriate information (relating to the intentions of such Holders) in connection therewith as the Company shall reasonably request in writing. Following the effective date of such Registration Statement or notification, the Company shall, upon the request of the Seller, forthwith supply such number of Prospectuses or offering circulars meeting the requirements of the Securities Act as shall be reasonably requested -7- 8 by such Seller to permit such Seller to make a public offering of all such securities of such Seller included therein. The Company shall file such Blue Sky Applications and use its best efforts to qualify such securities included therein for sale in such states as the Sellers shall reasonably designate. (ii) The Company shall bear the cost and expense directly relating to any registration securities pursuant to this Section 9.1, provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to this Section 9.1 if the Registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all Holders requesting such Registration shall bear such expenses). The Company shall not be required to pay any selling commissions, but shall pay all applicable listing fees. (iii) The Company shall indemnify and hold harmless each Seller who may purchase from or sell for any Seller any Registrable Securities from and against any and all losses, claims, damages and liabilities caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any Prospectus included therein, required to be filed or furnished by reason of this Section 9.1, or caused by any omission or alleged omissions to state therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or alleged untrue statement or omission or alleged omission which was based upon information furnished or required to be furnished in writing to the Company by and about such Seller expressly for use therein, which indemnification shall include each person, if any, who controls any such Seller within the meaning of the Securities Act; provided, however, that the Company shall not be obliged so to indemnify any such Seller or controlling persons unless such Seller shall at the same time indemnify the Company, its directors, each officer signing a Registration Statement or notification and each person, if any who controls the Company within the meaning of the Securities Act from and against any and all losses, claims, damages and liabilities caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or notification or any Prospectus or offering circular required to be filed or furnished by reason of this Section 9.1, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statement therein, in light of the circumstances under which they were made, not misleading, insofar as such losses, claims, damages or liabilities are caused by any untrue statement or alleged untrue statement or omission or alleged omission which was based upon information furnished in writing to the Company by and about such Seller expressly for use therein. (iv) The Company will, or will use its best efforts to (i) prepare and file with the Commission a Registration Statement or notification with respect to the Registrable Securities to be registered or qualified and cause such Registration Statement or notification to become and remain effective; provided, that the Company will not be required to keep the Registration Statement or notification effective, or to prepare and file any amendments or supplements, later than nine months after the date on which the Registration Statement or notification becomes effective under the Securities Act. -8- 9 (v) The Company shall, in case of a registration or notification, furnish to the Holders of the Registrable Securities for whom such Registrable Securities are registered or are to be registered or are filed for notification, at the time such Registration Statement becomes effective, an opinion of counsel, dated such date, for the Company reasonably acceptable to the Holders to the effect that a Registration Statement or notification covering the Registrable Securities has been filed with the commission under the Securities Act and has become effective, that a prospectus or offering circular complying in form with the requirements of the Securities Act is available for delivery, that to the best of such counsel's knowledge, no stop order has been issued by the Commission suspending the effectiveness of the Registration Statement or suspending the availability of the offering exemption and that, to the best of the counsel's knowledge, no proceedings for the issuance of a stop order are threatened or contemplated, and that the Registrable Securities have been registered or qualified under the securities or Blue Sky Laws of each state in which the Company is required, pursuant to subsection (b)(i) of this Section 9.1 to register or qualify the Registrable Securities. (vi) It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 9.1 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be reasonably required to effect the Registration of such Holder's Registrable Securities. 9.2 Exchange Listing. In connection with the issuance of any Shares upon the exercise of this Warrant, the Company shall secure the listing of the underlying shares of Common Stock upon any securities exchange upon which shares of the Company's Common Stock are listed. 9.3 No Obligations to Sell. Neither the giving of any notice nor the making of any request hereunder shall impose any obligation on the selling Holder to sell any Registrable Securities. 9.4 Registration Rights Survive Exercise. The Company's obligations under this Section 9 shall continue in effect, regardless of the exercise or surrender of this Warrant. The Company's obligations under this Section 9 shall expire, however, with respect to a Warrant or Shares which have been sold by a broker or dealer or in a public offering registered under the Securities Act or a public offering exempt from such registration. SECTION 10 SECURITIES LAW COMPLIANCE Except pursuant to the requirements of Rule 144 of the Securities Act, this Warrant and the Shares may not be sold, transferred, assigned or otherwise disposed of except as follows: -9- 10 (a) to a person who, in the opinion of counsel reasonably satisfactory to the Company, is a person to whom this Warrants or the Shares may legally be transferred without registration and without the delivery of a current prospectus or offering circular with respect thereto; or (b) to any person upon delivery of a prospectus or offering circular then meeting the requirements of the Securities Act relating to such securities (as to which a Registration Statement or notification under the Securities Act shall then be in effect) and the offering thereof for such sale or disposition. SECTION 11 REDEMPTION The Company may call the Warrants for redemption, in whole or in part, upon at least thirty (30) days' prior written notice at any time during the exercise period at a price of $.05 per Warrant, provided that the closing bid price for a share of the Company's Common Stock has been an average of at least $3.375 for twenty (20) trading days immediately preceding the date of the written notice. In the event the Company exercises its right to redeem the Warrants, such Warrants will be exercisable until the close of business on the date fixed for redemption in such notice. If any Warrant called for redemption is not exercised by such time, it will cease to be exercisable and the Holder thereof will be entitled to the redemption price.
