          additional shares of Common Stock in stock dividend, stock
          distribution or subdivision paid with respect to Common Stock, or
          declare any dividend or other distribution payable with additional
          shares of Common Stock (or securities convertible into Common Stock)
          with respect to Common Stock or effect a split or subdivision of the
          outstanding shares of the Company's Common Stock, the Purchase Price
          then in effect immediately prior to such stock dividend, stock
          distribution or subdivision or such declaration thereof, shall,
          concurrently with the effectiveness of such stock dividend, stock
          distribution or subdivision, or the earlier declaration thereof, be
          proportionately decreased and the number of shares of Common Stock
          issuable upon exercise of this Option shall be appropriately increased
          in proportion to such increase of outstanding shares.

     b)   In the event the outstanding shares of Common Stock shall at any time
          after the date hereof be combined or consolidated, by reclassification
          or otherwise, into a lesser number of shares of Common Stock, the
          Purchase Price then in effect immediately prior to such combination or
          consolidation shall, concurrently with the effectiveness of such
          combination or consolidation, be proportionately increased and the
          number of shares of Common Stock issuable upon exercise of this Option
          shall be appropriately decreased in proportion to such decrease in

     c)   In case, at any time after the date hereof, of any consolidation or
          merger of the Company with or into another corporation or the
          conveyance of all or substantially all of the assets of the Company to
          another corporation, the shares of Common Stock issuable upon the
          exercise of this Option shall thereafter be convertible into the
          number of shares of stock or other securities or property to which a
          holder would have been entitled if immediately prior to such
          consolidation, merger or conveyance he had exercised this Option in
          its entirety; and in any such case, appropriate adjustment (as
          determined in good faith by the Board of Directors) shall be made in
          the application of the provisions herein set forth with respect to the
          rights and interest thereafter of the holder of this Option and that
          the provisions set forth herein (including provisions with respect to
          changes in and other adjustments of the Purchase Price) shall
          thereafter be

          applicable, as nearly as reasonably may be, in relation to any shares
          of stock or other property thereafter deliverable upon the exercise of
          this Option.

     d)   All calculations under this Paragraph 9 shall be made to the nearest
          cent or to the nearest share, as the case may be.

     e)   No adjustment in the Purchase Price need be made if such adjustment
          would be less than $0.01. Any adjustment of less than $0.01 which is
          not made shall be carried forward and shall be made at the time of and
          together with any subsequent adjustment which, on a cumulative basis,
          amounts to any adjustment of $0.01 or more in the Purchase Price.

     f)   The Company will, at all times, in good faith assist in carrying out
          all the provisions of this Paragraph 9 and in the taking of all such
          action as may be necessary or appropriate to protect the rights of the
          holder of this Option from impairment.

     g)   Upon the occurrence of each adjustment or readjustment of the Purchase
          Price pursuant to this Paragraph 9, the Company at its expense shall
          promptly compute such adjustment or readjustment in accordance with
          the terms hereof and prepare and furnish to the holder of this Option
          a certificate setting forth adjustment or readjustment and showing in
          detail the facts upon which such adjustment or readjustment is based.
          The Company shall, upon written request at any time of the holder of
          this Option, furnish or cause to be furnished to such holder a like
          certificate setting forth:

          i)   such adjustments and readjustments;

          ii)  the Purchase Price at the time in effect; and

          iii) the number of shares of Common Stock and the amount, if any, of
               other property that at the time would be received upon the
               exercise of this Option.

     h)   In the event of any taking by the Company of a record of the holders
          of any class of securities for the purpose of determining the holders
          thereto who are entitled to receive any dividend (other than a cash
          dividend) or other distribution, the Company shall mail to the holder
          of this Option at least twenty (20) days prior to such record day, a
          notice specifying the date on which any such record is to be taken for
          the purpose of such dividend or distribution.

     i)   The Company shall at all times reserve and keep available out of the
          authorized but unissued shares of the Common Stock, solely for the
          purpose of effecting the exercise of this Option, such number of its
          shares of Common Stock as shall from time to time be sufficient to
          effect the exercise of this Option; and if at any time the number of
          authorized but unissued shares of Common Stock shall not be sufficient
          to affect the exercise of this Option, the Company will take such
          corporate action as may, in the opinion of its counsel, be necessary
          to increase its authorized but unissued shares of Common Stock to such
          number of shares as shall be sufficient for such purpose.

          Bylaws 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

          such actions as may be necessary or appropriate in order to protect
          the rights of the holders of this Option against impairment.

          determined in good faith by the Board of Directors) shall be made in
          the application of the provisions herein set forth with respect to the
          rights and interest thereafter of the holder of this Warrant and that

          of stock or other property thereafter deliverable upon the exercise of
          this Warrant.

     d)   All calculations under this Paragraph 9 shall be made to the nearest
          cent or to the nearest one tenth (1/10) of a share, as the case may
          be.

     e)   No adjustment in the Purchase Price need be made if such adjustment
          would be less than $0.01. Any adjustment of less than $0.01 which is
          not made shall be carried forward and shall be made at the time of and
          together with any subsequent adjustment which, on a cumulative basis,

          terms hereof and prepare and furnish to the holder of this Warrant a
          certificate setting forth adjustment or readjustment and showing in
          detail the facts upon which such adjustment or readjustment is based.
          The Company shall, upon written request at any time of the holder of
          this Warrant, furnish or cause to be furnished to such holder a like
          certificate setting forth:

          i)   such adjustments and readjustments;

          ii)  the Purchase Price at the time in effect; and

          iii) the number of shares of Common Stock and the amount, if any, of

          dividend) or other distribution, the Company shall mail to the holder
          of this Warrant at least twenty (20) days prior to such record day, a

          purpose of effecting the exercise of this Warrant, such number of its
          shares of Common Stock as shall from time to time be sufficient to
          effect the exercise of this Warrant; and if at any time the number of
          authorized but unissued shares of Common Stock shall not be sufficient
          to affect the exercise of this Warrant, the Company will take such
          corporate action as may, in the opinion of its counsel, be necessary
          to increase its authorized but unissued shares of Common Stock to such
          number of shares as shall be sufficient for such purpose.
