for Dividends or Distributions of Stock or Other Securities or           Property. In
case the Company shall make or issue, or shall fix a record           date for the
determination of eligible holders entitled to receive, a dividend           or other
distribution with respect to the Common Stock (or any shares of stock           or other

assets of the Company to which such Holder would have been entitled upon           such
date if such Holder had exercised this Warrant on the date hereof and had
          thereafter, during the period from the date hereof to and including the date of
          such exercise, retained such shares and/or all other additional stock available
          by it as aforesaid during such period giving effect to all adjustments called
          for by this Section 4.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 4.3.              Reclassification.
If the Company, by reclassification of securities or           otherwise, shall change
any of the securities as to which purchase rights under           this Warrant exist into
the same or a different number of securities of any           other class or classes,
this Warrant shall thereafter represent the right to           acquire such number and
kind of securities as would have been issuable as the           result of such change
with respect to the securities that were subject to the           purchase rights under
this Warrant immediately prior to such reclassification or           other change and the
Purchase Price therefore shall be appropriately adjusted,           all subject to
further adjustment as provided in this Section 4. No adjustment           shall be made
pursuant to this Section 4.3 upon any conversion or redemption of           the Common
Stock which is the subject of Section 4.5.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 4.4.              Adjustment
for Capital Reorganization, Merger or Consolidation. In case           of any capital
reorganization of the capital stock of the Company (other than a           combination,
reclassification, exchange or subdivision of shares otherwise           provided for
herein), or any merger or consolidation of the Company with or into           another
corporation, or the sale of all or substantially all the assets of the           Company
then, and in each such case, as a part of such reorganization, merger,
          consolidation, sale or transfer, lawful provision shall be made so that the
          Holder of this Warrant shall thereafter be entitled to receive upon exercise of
          this Warrant, during the period specified herein and upon payment of the
          Purchase Price then in effect, the number of shares of stock or other
securities           or property of the successor corporation resulting from such
reorganization,           merger, consolidation, sale or transfer that a holder of the
shares deliverable           upon exercise of this Warrant would have been entitled to
receive in such           reorganization, consolidation, merger, sale or transfer if this
Warrant had been           exercised immediately before such reorganization, merger,
consolidation, sale or           transfer, all subject to further adjustment as provided
in this Section 4. The           foregoing provisions of this Section 4.4 shall similarly
apply to successive           reorganizations, consolidations, mergers, sales and
transfers and to the stock           or securities of any other corporation that are at
the time receivable upon the           exercise of this Warrant. If the per-share
consideration payable to the Holder           hereof for shares in connection with any
such transaction is in a form other           than cash or marketable securities, then
the value of such consideration shall           be determined in good faith by the Companys
Board of Directors. In all           events, appropriate adjustment (as determined in
good faith by the           Companys Board of Directors) shall be made in the
application of the           provisions of this Warrant with respect to the rights and
interests of the           Holder after the transaction, to the end that the provisions
of this Warrant           shall be applicable after that event, as near as reasonably may
be, in relation           to any shares or other property deliverable after that event
upon exercise of           this Warrant.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 4.5.              Conversion
of Common Stock. In case all or any portion of the authorized           and
outstanding shares of Common Stock of the Company are converted or           reclassified
into other securities or property pursuant to the Companys           Articles of
Incorporation or otherwise, or the Common Stock otherwise ceases to           exist,
then, in such case, the Holder of this Warrant, upon exercise hereof at           any
time after the date on which the Common Stock is so redeemed or converted,
          reclassified or ceases to exist (the Termination           Date),
shall receive, in lieu of the number of shares of           Common Stock that would have
been issuable upon such exercise immediately prior           to the Termination Date, the
securities or property that would have been           received if this Warrant had been
exercised in full and the Common Stock           received thereupon had been
simultaneously converted immediately prior to the           Termination Date, all subject
to further adjustment as provided in this Warrant.           Additionally, the Purchase
Price shall be immediately adjusted to equal the           quotient obtained by dividing
(x) the aggregate Purchase Price of the           maximum number of shares of Common
Stock for which this Warrant was exercisable           immediately prior to the
Termination Date by (y) the number of shares of           Common Stock of the
Company for which this Warrant is exercisable immediately           after the Termination
Date, all subject to further adjustment as provided           herein.

5.       
          CERTIFICATE AS TO ADJUSTMENTS.In each case of any adjustment in the
          Purchase Price, or number or type of shares issuable upon exercise of this
          Warrant, the Chief Financial Officer or Controller of the Company shall compute
          such adjustment in accordance with the terms of this Warrant and prepare a
          certificate setting forth such adjustment and showing in detail the facts upon
          which such adjustment is based, including a statement of the adjusted Purchase
          Price. The Company shall promptly send (by facsimile and by either first class
          mail, postage prepaid or overnight delivery) a copy of each such certificate to
          the Holder.

6.       
          LOSS OR MUTILATION.Upon receipt of evidence reasonably satisfactory to
          the Company of the ownership of and the loss, theft, destruction or mutilation
          of this Warrant, and of indemnity reasonably satisfactory to it, and (in the
          case of mutilation) upon surrender and cancellation of this Warrant, the Company
          will execute and deliver in lieu thereof a new Warrant of like tenor as the
          lost, stolen, destroyed or mutilated Warrant.

7.       
          RESERVATION OF COMMON STOCK.The Company hereby covenants that at all
          times there shall be reserved for issuance and delivery upon exercise of this
          Warrant such number of shares of Common Stock or other shares of capital stock
          of the Company as are from time to time issuable upon exercise of this Warrant
          and, from time to time, will take all steps necessary to amend its Articles of
          Incorporation to provide sufficient reserves of shares of Common Stock issuable
          upon exercise of this Warrant (and shares of its Common Stock for issuance on
          conversion of such Common Stock). All such shares 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 restrictions on sale and free and clear of all preemptive
          rights, except encumbrances or restrictions arising under federal or state
          securities laws or restrictions provided for in Section 9 below. Issuance of
          this Warrant shall constitute full authority to the Companys officers who
          are charged with the duty of executing stock certificates to execute and issue
          the necessary certificates for shares of Common Stock upon the exercise of this
          Warrant.

8.       
          TRANSFER AND EXCHANGE.Subject to the terms and conditions of this
          Warrant and compliance with all applicable securities laws, this Warrant and all
          rights hereunder may be transferred in whole or in part, on the books of the
          Company maintained for such purpose at the principal office of the Company
          referred to above, to any Registered Holder parent, subsidiary or affiliate, by
          the Registered Holder hereof in person, or by duly authorized attorney, upon
          surrender of this Warrant properly endorsed and upon payment of any necessary
          transfer tax or other governmental charge imposed upon such transfer. Upon any

          Holder a new Warrant or Warrants with respect to the shares of Common Stock not
          so transferred. Each taker and holder of this Warrant, by taking or holding the
          same, consents and agrees that when this Warrant shall have been so endorsed,
          the person in possession of this Warrant may be treated by the Company, and all

| | (a)       
               it will not sell, transfer, pledge or hypothecate any or all of this Warrant
               without the prior written consent of the Company, which consent may be withheld
               in the Companys sole and absolute discretion; and
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b)       
               notwithstanding any consent given by the Company under Section 9(a) hereof,

               Securities Act of 1933, as amended (the 1933 Act), covering
               the disposition or sale of this Warrant or the Common Stock issued or issuable
               upon exercise hereof or the Common Stock issuable upon conversion thereof, as
               the case may be, and registration or qualification under applicable state
               securities laws, such Holder will not sell, transfer, pledge, or hypothecate any
               or all such Warrants or Common Stock, as the case may be, unless either
               (i) the Company has received an opinion of counsel, in form and substance
               reasonably satisfactory to the Company, to the effect that such registration is
               not required in connection with such disposition or (ii) the sale of such
               securities is made pursuant to SEC Rule 144.

          COMPLIANCE WITH SECURITIES LAWS.By acceptance of this Warrant, the
          holder hereby represents, warrants and covenants that any shares of stock
          purchased upon exercise of this Warrant or acquired upon conversion thereof
          shall be acquired for investment only and not with a view to, or for sale in
          connection with, any distribution thereof; that the Holder has had such
          opportunity as such Holder has deemed adequate to obtain from representatives of

          to bear the economic risk of holding such shares as may be acquired pursuant to
          the exercise of this Warrant for an indefinite period; that the Holder
          understands that the shares of stock acquired pursuant to the exercise of this
          Warrant or acquired upon conversion thereof will not be registered under the
          1933 Act (unless otherwise required pursuant to exercise by the Holder of
          registration rights, if any, previously granted to the registered Holder) and
          will be restricted securities within the meaning of Rule 144 under
          the 1933 Act and that the exemption from registration under Rule 144 will not be

          stock, adequate information concerning the Company is then available to the
          public, and other terms and conditions of Rule 144 are complied with; and that
          all stock certificates representing shares of stock issued to the Holder upon
          exercise of this Warrant or upon conversion of such shares may have affixed
          thereto a legend substantially in the following form:
