        SECTION
2.    Exercise of Warrant.    


        (a)   On
and after the Effective Date and until 5:00 p.m., California time, on the Expiration Date, the Holder may exercise this Warrant, on one or more occasions, on
any Business Day, in whole or in part, by delivering to the Issuer, at its office maintained for such purpose pursuant to Section 5 hereof,
(i) a written notice of the Holder's election to exercise this Warrant, which notice shall be substantially in the form of Annex A attached
hereto and shall be properly completed (the "Exercise Notice"), (ii) payment of the Exercise Price (payable as set forth in  Section 2(b) below)
for the Warrant Stock as to which this Warrant is being exercised, and (iii) this Warrant. Except to the extent
necessary to cause the number of shares of Common Stock deliverable as provided in Section 2(b) to be a whole number of shares, this Warrant
shall be exercisable in part only for a whole number of shares. 


        (b)   At
the option of the Holder, the Exercise Price shall be payable (i) in cash or by certified or official bank check payable to the order of the Issuer or
(ii) by exchange of this Warrant in accordance with the further provisions of this Section 2(b). In exchange for the portion of this
Warrant that is being exercised at such time, the Holder shall receive the number of shares of Common Stock determined by multiplying (A) the number of shares of Common Stock for which this
Warrant is being exercised at such time by (B) a fraction, (1) the numerator of which shall be the difference between (x) Current Market Price per share of Common Stock at such
time and (y) the Exercise Price per share of Common Stock, and (2) the denominator of which shall be the Current Market Price per share of Common Stock at such time. The Issuer shall
issue a new Warrant for the portion, if any, of this Warrant not being exercised as provided in Section 2(f). 



        (c)   Subject
to the provisions of Section 2(d), upon receipt of an Exercise Notice, the aggregate Exercise Price
payable and this Warrant, the Issuer shall, as promptly as practicable and in any event within five (5) Business Days thereafter, issue to the Holder one or more stock certificates representing
the aggregate number of shares of Common Stock to which the Holder is entitled and transfer to the Holder of this Warrant appropriate evidence of ownership of other securities or property (including
any cash) to which the Holder is entitled, in such denominations, and registered or otherwise placed in, or payable to the order of, such name or names, as may be directed in writing by the Holder
(subject to restrictions on transfer contained herein), and shall deliver such stock certificates, evidence of ownership and any other securities or property (including any cash) to the Person or
Persons entitled to receive the same, together with an amount in cash in lieu of any fraction of a share (or fractional interest in any other security), as hereinafter provided. The Issuer shall pay
all expenses in connection with, and any and all documentary, stamp or similar issue or transfer taxes of the United States or any state thereof payable in respect of, the issue or delivery of the
Warrant Stock upon exercise of this Warrant. However, the Issuer shall not be required to pay any tax or other charge imposed in connection with any assignment or transfer involved in the issue of any
certificate or other evidence of ownership of Warrant Stock. 


3





 



        (d)   The
Holder's election to exercise this Warrant may, in the sole discretion of the Holder, be conditioned upon, and in such event, the exercise shall be subject in all
respects to a Change of Control, the consummation of a sale of the Issuer, any public offering of the Issuer's Common Stock registered under the Securities Act or other similar transaction involving
the Issuer (collectively referred to herein as the "Exercise Conditions"), as specified in the Exercise Notice, and the Issuer shall provide the Holder
with written notice no less than 20 Business Days prior to the occurrence of an Exercise Condition (or such shorter period of time as is practicable under the circumstances). If any exercise of this
Warrant is so conditioned, then, subject to delivery of the items required by Section 2(b), the Issuer shall deliver the certificates and other
evidence of ownership of other securities or other property in such manner as the Holder shall direct as required in connection with the consummation of the transaction upon which the exercise is
conditioned. At any time that the Issuer shall give notice to the Holder that such transaction has been abandoned or the Issuer has withdrawn from participation in such transaction, the Issuer shall
return the items delivered pursuant to Section 2(c) and the Holder's election to exercise this Warrant shall be deemed rescinded. 



        (e)   The
stock certificate or certificates or other evidence of ownership of Warrant Stock to be delivered pursuant to  Section 2(c) hereof shall be deemed to have been issued, and the Holder or any other
Person so designated to be named therein shall, to the
extent permitted by law, be deemed to have become a holder of record of the Warrant Stock represented thereby, including having the right to vote any voting securities included therein or to consent
or to receive notice as a shareholder, as of the date on which the last of the Exercise Notice, payment of the Exercise Price and this Warrant is received by the Issuer as aforesaid (subject, in the
case of an exercise to which Section 2(d) applies, to the transaction upon which such exercise is conditioned), notwithstanding that the transfer
books of the Issuer shall then be closed or that such certificates or other evidence of ownership shall not then actually have been delivered to the Holder. 


        (f)    If
this Warrant shall have been exercised only in part, the Issuer shall, at the time of delivery of the certificate or certificates or other evidence of ownership of
Warrant Stock, execute and deliver to the Holder, without charge, a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Stock called for by this Warrant, which new
Warrant shall in all other respects be identical to this Warrant, or, at the request of the Holder, appropriate notation may be made on this Warrant and the same returned to the Holder. 



        (g)   The
Issuer shall not be required to issue any fractional share of Common Stock (or fractional interest in any other security) upon exercise of this Warrant. As to any
fraction of a share (or fractional interest in any other security) that the Holder would otherwise be entitled to receive upon such exercise, the Issuer shall pay a cash adjustment in respect of such
fraction in an amount equal to the same fraction of the Current Market Price per share of Common Stock (and/or other security) on the date of exercise;  provided, however, that in the event that the Issuer undertakes a reduction in the number of shares of
Common Stock or other securities outstanding, it shall be required to issue fractional shares or fractional interests in such other securities to the Holder if the Holder exercises all or any part of
this Warrant, unless the Holder shall have consented in writing to such reduction and provided the Issuer with a written waiver of its right to receive fractional shares or interests in accordance
with this paragraph. If the Holder shall exercise more than one Warrant in the same transaction, any payment in respect of fractional shares (or other fractional interests) shall be based on the final
fraction resulting from aggregating all such exercises. 


        (h)   The
Issuer hereby agrees at all times to keep reserved for issuance and delivery upon exercise of this Warrant such number of its authorized but unissued shares (or
treasury shares) of Common Stock or other securities of the Issuer from time to time issuable upon exercise of this Warrant as will be sufficient to permit the exercise in full of this Warrant. All
such shares and other securities shall be duly authorized and, when issued upon such exercise, shall be validly issued, fully paid and non-assessable, free and clear of all liens, security
interests, charges and other encumbrances or 


4





 



restrictions
on sale (except to the extent of any applicable provisions set forth in the Issuer's Fundamental Documents) and free and clear of all preemptive or similar rights. 


        (i)    If
the issuance of any shares of Common Stock or other securities required to be reserved for purposes of the exercise of this Warrant requires the registration with, or
approval of, any governmental authority or requires listing on any national securities exchange or national market system before such shares or other securities may be so issued, the Issuer shall at
its expense use its best efforts to cause such shares to be duly registered, approved or listed, as the case may be, so that such shares or other securities may be issued in accordance with the terms
hereof; provided, however, that this provision shall not obligate the Issuer to register such shares or
other securities under the Securities Act or qualify them under state securities or blue sky laws. 


        SECTION
3.    Transfer, Division and Combination.    



        (a)   This
Warrant, all rights hereunder and any Warrant Stock issued or issuable upon exercise hereof are assignable and transferable, at any time in whole or in part, to any
Person or Persons, subject in all cases to the restrictions set forth in the legend to this Warrant. Any such transfer shall not require the consent of any security holder of the Issuer. 


        (b)   Upon
a transfer permitted by Section 3(a), this Warrant shall be transferable upon surrender of this Warrant to
the Issuer, together with a written assignment of this Warrant substantially in the form of Annex B attached hereto, duly executed by the Holder hereof
or such Holder's agent or attorney. Upon such surrender, the Issuer shall, without charge, execute and deliver a new Warrant or Warrants in the name of the assignee or assignees (and, if the Holder's
entire interest is not being assigned, in the name of the Holder), and in the denominations specified in such instrument of assignment, and this Warrant shall promptly be canceled. 


        (c)   This
Warrant may be exchanged for, or combined with, other Warrants upon presentation of this Warrant and any other Warrants with which this Warrant is to be combined to
the Issuer, together with a written notice specifying the denominations in which a new Warrant or Warrants are to be issued, signed by the Holder. The Issuer shall execute and deliver a new Warrant or
Warrants to the Holder in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. 


        (d)   The
Issuer shall maintain books for the registration and transfer of the Warrants, and shall allow each Warrant Holder to inspect such books at such reasonable times as
such Holder shall request. 


        SECTION
4.    Adjustments.    


        (a)    Dividends and Distributions.    If at any time on or after the Effective Date the Issuer shall pay any dividend
or make any other distribution to holders of its Common Stock of any cash, evidence of indebtedness or other property (including any rights or warrants to purchase any securities of the Issuer) of any
nature whatsoever (other than as contemplated by subsection (b) of this Section 4), the Issuer shall at the same time pay or distribute to
the Holder (whether or not the Holder exercises this Warrant) the cash, evidence of indebtedness or other property the Holder would have been entitled to receive if such Holder had exercised this
Warrant immediately prior to the record date for such dividend or distribution. 


        (b)    Subdivisions and Combinations.    If at any time the Issuer shall 



          (i)  take
a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution of Common Stock; 


         (ii)  subdivide,
split or reclassify its outstanding shares of Common Stock into a larger number of shares of Common Stock; or 



5





 




        (iii)  combine
its outstanding shares of Common Stock into a smaller number of shares of Common Stock; 




then
immediately after the occurrence of any such event (A) the number of shares of Common Stock issuable upon exercise of this Warrant shall be adjusted so as to equal the number of shares of
Common Stock such holder would have held immediately after the occurrence of such event (in the case of an event referred to in clause (i), after giving effect to such dividend or distribution)
if such holder had exercised this Warrant immediately prior to the occurrence of such event and (B) the Exercise Price shall be adjusted to be equal to (x) the Exercise Price immediately
prior to the occurrence of such event multiplied by (y) a fraction (1) the numerator of which is the number of shares of Common Stock issuable upon exercise of this Warrant immediately
prior to the adjustment in clause (A) and (2) the denominator of which is the number of shares of Common Stock issuable upon exercise of this Warrant immediately after the adjustment in
clause (A). 


        (c)    Merger, Consolidation or Disposition of Assets.    If the Issuer shall merge, consolidate or effect a share
exchange with another entity, or shall sell, transfer or otherwise dispose of all or substantially all of its assets to another entity and pursuant to the terms of such merger, consolidation, share
exchange or disposition of assets, cash, shares of Common Stock or other securities of the successor or acquiring entity, or property of any nature is to be received by or distributed to the holders
of Common Stock of the Issuer, then the Holder shall be entitled to receive upon the exercise of this Warrant in accordance with its terms, in respect of the Warrant Stock issuable upon exercise of
this Warrant, and upon delivery to the Issuer or the Issuer's successor, as applicable, of this Warrant for cancellation, the amount of cash, shares of Common Stock, other securities or other property
that it would have been entitled to receive if such Holder had exercised this Warrant in full immediately prior to the occurrence of such merger, consolidation, share exchange or disposition of
assets. In the case of any such merger, consolidation, share exchange or disposition of assets, the successor or acquiring entity (and any Affiliate thereof issuing securities) shall expressly assume
the due and punctual observance and performance of each and every covenant and condition of this Warrant to be performed and observed by the Issuer and all of the obligations and liabilities
hereunder, subject to such modifications as may be deemed appropriate (as determined by resolution of the Board) in order to provide for adjustments of the Warrant Stock issuable upon exercise of this
Warrant that shall be as nearly equivalent as practicable to the adjustments provided for in this Section 4. The foregoing provisions shall similarly apply to successive mergers,
consolidations, share exchanges and dispositions of assets. 


        (d)    Capital Reorganization or Capital Reclassification.    If the Issuer shall effect any capital reorganization or
any reclassification of its capital stock (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision,
split-up or combination of shares), then in each case the Issuer shall cause effective provision to be made so that this Warrant shall be exercisable for the kind and number of shares of
stock, other securities, cash or other property to which a holder of the Warrant Stock deliverable upon exercise of this Warrant would have been entitled upon such reorganization or reclassification
and any such provision shall include adjustments in respect of such stock, securities or other property that shall be as nearly equivalent as may be practicable to the adjustments provided for in this  Section 4 with respect to this Warrant. 



        (e)    Notice of Certain Corporate Action.    If the Issuer shall propose (i) to pay any dividend to the
holders of its Common Stock or to make any other distribution to the holders of its Common Stock; (ii) to offer to the holders of its Common Stock rights to subscribe for or to purchase any
additional shares of Common Stock; (iii) to effect any reorganization or reclassification of its Common Stock; (iv) to otherwise issue any Common Stock; (v) to effect any other
capital reorganization; (vi) to effect any consolidation, merger or share exchange or any sale, transfer or other disposition of all or substantially all of its assets; or (vii) to
effect the liquidation, dissolution or winding up of the Issuer, 


6





 



then,
in each such case, the Issuer shall give to the Holder a notice of such proposed action, which shall specify the date on which a record is to be taken for the purposes of such dividend,
distribution or rights offer, or the date on which such reclassification, issuance, reorganization, consolidation, merger, share exchange, sale, transfer, disposition, liquidation, dissolution or
winding up is to take place and the date of participation therein by the holders of Common Stock, if any such date is to be fixed, and shall also set forth such facts with respect thereto as shall be
reasonably necessary to indicate the effect of such action on the Common Stock, and the number of shares of Warrant Stock that are issuable upon exercise of this Warrant after giving effect to any
adjustment that will be required as a result of such action. Such notice shall be so given in the case of any action covered by clause (i) or (ii) above at least 10 days prior to
the record date for determining holders of the Common Stock for purposes of such action, and in the case of any other such action, at least 10 days prior to the date of the taking of such
proposed action. 


        (f)    No Impairment.    The Issuer will not, by amendment of its Certificate of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the
terms to be observed or performed hereunder by the Issuer, but will at all times in good faith assist in the carrying out of all the provisions of this  Section 4 and in the taking of all such
action as may be necessary or appropriate in order to protect the exercise rights of the Holder against
impairment. 


        (g)    Miscellaneous.    The computations of all amounts under this  Section 4 shall be made assuming all other anti-dilution
or similar adjustments to be made to the terms of all other securities
resulting from the transaction causing an adjustment pursuant to this Section 4 have previously been
made so as to maintain the relative economic interest of this Warrant vis a vis all other securities issued by the Issuer. 


        SECTION
5.    Miscellaneous.    


        (a)    Office of Issuer.    So long as this Warrant remains outstanding, the Issuer shall maintain an office in the
continental United States where the Warrants may be presented for exercise, transfer, division or combination as provided in this Warrant. Such office shall be at its principal executive offices
unless and until the Issuer shall designate and maintain some other office for such purposes and give notice thereof to the Holder. 


        (b)    Notices Generally.    All notices, requests, consents and other communications hereunder to any party shall be
deemed to be sufficient if contained in a written instrument delivered in person or sent by telecopy, nationally-recognized overnight courier or first class registered or certified mail, return
receipt requested, postage prepaid, addressed to such party at the address set forth below or such other address as may hereafter be designated in writing by such party to the other parties:

        (c)    Governing Law.    This Warrant shall be governed by and construed in accordance with the laws of the State of

against it in the courts of such State or any Federal court located in such State. 


        (d)    Limitation of Liability.    Except as otherwise provided herein, this Warrant does not entitle the Holder to
any voting rights or other rights of a shareholder of the Issuer, as a shareholder. No provision hereof, in the absence of affirmative action by the Holder to purchase shares of Common Stock, and no
mere enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the Exercise Price or as a shareholder of the Issuer, whether such liability is
asserted by the Issuer, by any creditor of the Issuer or any other Person. 


        (e)    Loss or Destruction of Warrant.    Upon receipt by the Issuer of evidence satisfactory to it (in the exercise
of its reasonable discretion) of the loss, theft, destruction or mutilation of this Warrant and (in the case of loss, theft or destruction), if requested by the Issuer, of reasonably satisfactory
indemnification, or (in the case of mutilation) upon surrender and cancellation of this Warrant, the Issuer shall, without charge, execute and deliver a new Warrant exercisable for the same amount of
Warrant Stock; provided, however, that (in the case of loss, theft or destruction) no indemnity bond
shall be required unless the Issuer has a class of securities registered pursuant to the Securities Exchange Act of 1934, as amended, and the Issuer's transfer agent requires such indemnity bond as a
condition to the issuance of a new Warrant. 


        (f)    Amendments and Waivers.    Any provision of this Warrant may be amended or waived if, and only if, such
amendment or waiver is in writing and signed by the Issuer and the Holder and, in the case of a waiver, by the party against whom the waiver is to be effective. No failure or delay by either party in
exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of
any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.
