(c)
    
    If this Warrant is exercised in part only, the Company shall
execute and deliver a new Warrant of the same tenor evidencing the right of the
Holder to purchase the balance of the Shares purchasable hereunder upon the

 Valid Issuance of Shares
 Adjustments
 (a)
    
    Subdivisions, Combinations and Other Issuances. If the Company
shall at any time prior to the expiration of this Warrant subdivide its Common
Stock, by stock split or otherwise, or combine its Common Stock, or issue
additional shares of its Common Stock as a dividend with respect to any shares
of its Common Stock, the number of Shares issuable on the exercise of this
Warrant shall forthwith be proportionately increased in the case of a
subdivision or stock dividend, or proportionately decreased in the case of a
combination. In such event, the Exercise Price shall be adjusted to equal (i)
the Exercise Price in effect immediately prior to such adjustment multiplied by
the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the adjustment divided by (ii) the number of shares for
which this Warrant is exercisable immediately after such adjustment. Any
adjustment under this Section 6(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective, or as of
the record date of such dividend, or in the event that no record date is fixed,
upon the making of such dividend.
 (b)
    
    Reclassification, Reorganization and Consolidation. In case of
any reclassification, capital reorganization, or change in the Common Stock of
the Company (other than as a result of a subdivision, combination, or stock
dividend provided for in Section 6(a) above), then, as a condition of such
reclassification, reorganization or change, lawful provision shall be made, and
duly executed documents evidencing the same from the Company or its successor
shall be delivered to Holder, so that Holder shall have the right at any time
prior to the expiration of this Warrant to purchase the kind and amount of
 shares of stock and other securities and property receivable in connection with
such reclassification, reorganization, or change by a holder of the same number
of shares of Common Stock as were purchasable by Holder immediately prior to
such reclassification, reorganization, or change, and the exercise price
therefor shall be appropriately adjusted. In any
such case appropriate provisions shall be made with respect to the rights
and interest of Holder so that the provisions hereof shall thereafter be
applicable with respect to any shares of stock or other securities and
property deliverable upon exercise hereof.

(c)
    
    Limitation on Adjustments. Notwithstanding the foregoing, no
adjustment in the Exercise Price shall be required unless such adjustment would
require an increase or decrease of at least one cent ($.01) in such price;
provided, however, that any adjustments which by reason of this Section 6 are
not required to be made shall be carried forward and taken into account in any
subsequent adjustment. Notwithstanding anything in this Section 6 to the
contrary, the Exercise Price shall not be reduced to less than the then
existing par value of the Common Stock as a result of any adjustment made
hereunder.
