to upon exercise of this Warrant.

6.3 In case of any reclassification or change of the Warrant Shares issuable
upon exercise of this Warrant (other than a change in par value or from no par
value to a specific par value, or as a result of a subdivision or combination,
including any change in the shares into two or more classes or series of
shares), or in the case of any consolidation or merger of another corporation
into the Company in which the Company is the continuing corporation and in which
there is a reclassification or change (including a change in the right to
receive cash or other property) of the

<PAGE>

Shares (other than a change in the par value, or from no par value to a specific
par value or, as a result of a subdivision or combination, including any change
in the shares into two or more classes or series of shares), Holder shall have
the right thereafter to receive upon exercise of this Warrant solely the kind
and amount of shares of stock and other securities, property, cash or
combination thereof receivable upon such reclassification, change, consolidation
or merger by a holder of the number of Shares for which this Warrant might have
been exercised immediately prior to such reclassification, change, consolidation
or merger.

6.4 Upon the occurrence of each event requiring an adjustment of the Exercise
Price and the number of Warrant Shares purchasable at such adjusted Exercise
Price by reason of such event in accordance with the provision of this Section
6, the Company shall compute the adjusted Exercise Price and the adjusted number
of Warrant Shares purchasable at such adjusted Exercise Price by reason of such
event in accordance with the provisions of this Section 6 and shall prepare a
certificate setting forth such adjusted Exercise Price and the adjusted number
of Warrant Shares and showing in reasonable detail the facts upon which such
determination is made. The Company shall mail to the holder of this Warrant a
copy of such Certificate, and thereafter said certificate shall be conclusive
and shall be binding upon such holder unless contested by such holder in a
written notice furnished to the Company within 15 days of the receipt thereof
setting forth in reasonable detail the basis of such contention.

6.5 In case:

(a) the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend or any other distribution in
respect of the Common Stock (including cash), pursuant to without limitation,
any spin-off, split-off or distribution of the Company's assets; or

(b) the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to subscribe for or purchase any shares of stock of
any class or to receive any other rights; or

(c) of any classification, reclassification or other reorganization of the
capital stock of the Company, consolidation or merger of the Company with or
into another corporation, or conveyance of all or substantially all of the
assets of the Company; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of
the Company;

then, and in any such case, the Company shall mail to the Holder, at least
twenty (20) days prior thereto, a notice stating the date or expected date on
which a record is to be taken for the purpose of such dividend or distribution
of rights, or the date on which such classification, reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation, or
winding up is to take place, as the case may be. Such notice shall also specify
the date or expected date, if any is to be fixed, as of which holders of Common
Stock of record shall be entitled to participate in said dividend on
distribution of rights, or shall be entitled to exchange their shares of Common
stock for securities or other property deliverable upon such classification,

<PAGE>

reclassification, reorganization, consolidation, merger, conveyance,
dissolution, liquidation, or winding up, as the case may be. The failure to give
such notice shall not affect the validity of any such proceeding or transaction
and shall not affect the right of the holder of this Warrant to participate in
said dividend, distribution of rights, or any such exchange and acquire the kind
and amount of cash, securities or other property as the Holder would have been
entitled to acquire if it was the record holder of the Warrant Shares which
could be obtained upon the exercise of the Warrants immediately before such
proceeding or transaction; provided that the Holder exercises the Warrants
within 30 days after discovery that such action or proceeding has taken place.

6.6 In case the Company at any time while this Warrant shall remain unexpired
and unexercised, shall dissolve, liquidate, or wind up its affairs, the holder
of this Warrant may thereafter receive upon exercise hereof in lieu of each
share of Common Stock of the Company which it would have been entitled to
receive, the same kind and amount of any securities or assets as may be
issuable, distributable or payable upon any such dissolution, liquidation or
winding up with respect to each share of Common Stock of the Company.

7. Limited Transfer

7.1 The Company may treat the registered holder of record as the holder for all
purposes.

7.2 In no event shall the Company be obligated to effect any transfer of
Warrants or Warrant Shares unless a registration statement is in effect with
respect thereto under applicable state and Federal securities laws or unless the
Company shall have received an opinion in substance reasonably satisfactory to
it from counsel that such registration is not required. Unless registered, the
Warrant Shares issued upon exercise of the Warrant shall be subject to a stop
transfer order and the certificate or certificates evidencing such Warrant
Shares shall bear the following legend:

            "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, ASAMENDED, PURSUANT TO A REGISTRATION
      STATEMENT. ACCORDINGLY, SUCH SHARES MAY NOT BE OFFERED OR SOLD EXCEPT
      PURSUANT TO A REGISTRATION STATEMENT UNDER SUCH ACT, OR AN EXEMPTION FROM
      REGISTRATION UNDER SUCH ACT."
