the number of Warrant Shares purchasable upon exercise of this Warrant
immediately prior thereto shall be adjusted by multiplying it by a fraction, the

such Adjustment Transaction; PROVIDED, HOWEVER, that the Company shall not issue
any fractional shares of Common Stock in any exercise of this Warrant, and the
number of shares of Common Stock issuable upon such exercise, if not a whole
number, shall be rounded up to the next whole number of shares.

the Board of Directors of the Company.

Warrant Shares (and other securities or property) purchasable upon the exercise
of this Warrant and the Exercise Price of such Warrant Shares after such
adjustment, setting forth a brief statement of the facts requiring such
adjustment and setting forth computation by which such adjustment was made. Such
notice, in absence of manifest error, shall be conclusive evidence of the
correctness of such adjustment.

Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any rights under this Warrant. The Company further
covenants that its issuance of this Warrant shall constitute full authority to
its officers who are charged with the duty of executing stock certificates to
execute and issue the necessary certificates for shares of the Company's Common
Stock upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
shares of Common Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the OTC Bulletin Board
