                  1.3 Certificates representing any Shares issued in a
transaction exempt from the registration requirements of the Securities Act of
1933, as amended (the "Securities Act") and applicable state securities laws, or
as to which the subsequent transfer or disposition of such Shares shall require
registration or qualification thereof under the Securities Act or applicable
state securities laws, shall bear a legend in substantially the following form:

                  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                  "SECURITIES ACT"), OR UNDER ANY APPLICABLE STATE SECURITIES
                  LAWS, OR ARE SUBJECT TO RESTRICTIONS ON TRANSFER UNDER THE
                  SECURITIES ACT OR SUCH LAWS. THE SHARES MAY NOT BE SOLD,
                  PLEDGED, TRANSFERRED, ASSIGNED OR OTHERWISE DISPOSED OF EXCEPT
                  IN A TRANSACTION WHICH IS EXEMPT UNDER THE PROVISIONS OF THE
                  SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, OR
                  PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR IN A
                  TRANSACTION OTHERWISE IN COMPLIANCE WITH APPLICABLE FEDERAL

without such legend, with respect to any of such Securities with respect to
which the Company has received an opinion from counsel to the Purchaser, in form
and substance and from counsel satisfactory to the Company (which opinion shall
be in addition to any opinion required to be provided pursuant to the other
provisions hereof), to the effect that the subsequent transfer or other
disposition of such Shares shall not require registration under the Securities
Act.

         2.       Reclassification, Consolidation or Merger
                  -----------------------------------------

                  2.1 In the event that the outstanding Shares are hereafter
changed by reason of reorganization, merger, consolidation, recapitalization,
reclassification, stock split-up, combination or exchange of Shares and the
like, or dividends payable in Shares, an appropriate adjustment shall be made by
the Board of Directors of the Company in the number of Shares and price per
Share subject to this Warrant. If the Company shall be reorganized,
consolidated, or merged with another corporation, or if all or substantially all
of the assets of the Company shall be sold or exchanged, the Warrant Holder
shall at the time of issuance of the stock under such a corporate event, be
entitled to receive upon the exercise of the Warrants evidenced by this

<PAGE>

Warrant and the payment of the exercise price therefor the same number and kind
of shares of stock or the same amount of property, cash or securities as he
would have been entitled to receive upon the occurrence of any such corporate
event as if he had been, immediately prior to such event, the holder of the
number of Shares covered by this Warrant Certificate.

                  2.2 Any adjustment under this Paragraph 2 in the number of
Shares subject to this Warrant Certificate shall apply proportionately to only
the unexercised portion hereunder and shall not have any retroactive effect with
respect to Warrants theretofore exercised. If fractions of a Share would result
from any such adjustment, the adjustment shall be revised to the next lower
whole number of Shares.

                  2.3 No adjustment of the exercise price shall be made if the
amount of such adjustment shall be less than $.10 per Share, but in such case
any adjustment that would otherwise be required then to be made shall be carried
forward and shall be made at the time and together with the next subsequent
adjustment which, together with any adjustment so carried forward, shall amount
to no less than $.10 per Share.

                  2.4 No fractional shares of Common Stock shall be issued upon
the exercise of this Warrant, but in lieu thereof the Company shall pay to the
order of Warrant Holder an amount in cash equal to the same fraction of the
exercise price of one Share on the date of exercise.

                  2.5 When any adjustment is required to be made in the exercise
price or number of Shares subject to this Warrant, the Company shall within
sixty (60) days after the date when the circumstances giving rise to the
adjustment occurred mail to the Warrant Holder a statement describing in
reasonable detail any method used in calculating such adjustment.

         3.       Prior Notice as to Certain Events
                  ---------------------------------

                  The Company shall mail to Warrant Holder not less than ten
(10) days prior to the date on which (a) a record will be taken for the purpose
of determining the holders of the capital stock of the Company entitled to
subscription rights or (b) a record will be taken (or in lieu thereof, the
transfer books will be closed) for the purpose of determining the holders of
such capital stock entitled to notice of and to vote at the meeting of
stockholders at which any consolidation, merger, dissolution, liquidation,
winding up or sale of the Company shall be considered and acted upon.

         4.       Reservation and Issuance of Shares
                  ----------------------------------

                  4.1 The Company covenants and agrees that the Shares issued
upon exercise of this Warrant pursuant to the terms hereof will be duly
authorized, validly issued and, when paid for in accordance with the terms
hereof, fully paid and nonassessable, and free from all liens and charges with
respect to the issue thereof to the Warrant Holder.

questions of the Company's management concerning the Company and the Securities.

laws, and the Securities may not be sold or otherwise transferred unless (a) the
Securities are sold or transferred pursuant to an effective registration
statement under the Securities Act or (b) the Purchaser shall have delivered to
the Company an opinion of counsel (which opinion shall be in form, substance and
scope customary for opinions of counsel in comparable transactions) to the
effect that the Securities to be sold or transferred may be sold or transferred
pursuant to an exemption from such registration; and (ii) neither the Company
nor any other Person is

exemption thereunder.
