with respect to the purchase and the issuance of the Stock.

         (c) Exercise Price. The exercise price of this Warrant, the price at

         (d) Exercise Period. This Warrant may only be exercised on or before a
day that is two (2) years after the date of issuance of this Warrant ("Exercise
Period"). If not exercised during this period, this Warrant and all rights
granted under this Warrant shall expire and lapse.

         (e) Tender. The exercise of this Warrant must be accomplished by actual
delivery of the Exercise Price in cash, certified check or official bank draft
in lawful money of the United States of America, and by actual delivery of a
duly exercised form, a copy of which is attached to this Warrant as Exhibit "A",
properly executed by the registered owner of this Warrant, and by surrender of

same are registered prior to exercise of this Warrant, shall be stamped or
otherwise imprinted with a legend in substantially the following form:

                  "The securities represented by this Certificate have not been
                  registered under the Securities Act of 1933, as amended, or
                  the securities laws of any state. The securities have been
                  acquired for investment and may not be sold, offered for sale
                  or transferred in the absence of an effective registration
                  under the Securities Act of 1933, as amended, and any
                  applicable state securities laws or an opinion of counsel
                  satisfactory in form and substance to counsel for the
                  Corporation that the transaction shall not result in a
                  violation of state or federal securities laws."

         (g) Adjustment of and Changes in the Shares.

         1.       Adjustments. If prior to exercise of this Warrant: (i) the
                  shares of Underlying Stock are changed into a different number
                  of shares by reason of reorganization, recapitalization,
                  combination of shares, stock split, reverse stock split or
                  reclassification; (ii) the Corporation declares and pays a
                  stock dividend on the Stock; or (iii) the Corporation's Stock
                  is changed into or exchanged for a different type of security
                  due to any reorganization, recapitalization, reclassification
                  or similar event, the Corporation shall make appropriate
                  adjustments in the number of shares or kind of securities
                  which you may purchase upon exercise of this Warrant so that
                  your proportionate shareholding interest in the Corporation
                  represented by the unexercised portion of this Warrant shall
                  be maintained as before the event. Adjustments in this Warrant
                  shall be made without change to the total price of the
                  unexercised portion of this Warrant and with a corresponding
                  adjustment in the Warrant price per share.

         2.       No Additional Rights. No issuance by the Corporation of shares
                  of stock of any class or securities convertible into shares of
                  any class, or the conversion of such securities into shares of
                  any class of stock, shall affect the number or price of shares
                  subject to this Warrant, and no adjustment by reason thereof
                  shall be made.

         3.       No Limitation on Corporation's Rights. Nothing herein shall
                  affect in any way the right or power of the Corporation to
                  make adjustments, reclassifications, reorganizations or
                  changes of its capital or business structure or to merge,
                  consolidate, dissolve, liquidate, sell or transfer all or any
                  part of its business or assets.


IN WITNESS WHEREOF, the Corporation has signed this Warrant by its duly
authorized officers this 15th day of March, 2000.
