commercially  reasonable  manner to obtain a fair and reasonable  sale price for
the Pledged Shares.  At any bona fide public sale Secured Party shall be free to
purchase all or any part of the Pledged Shares.  Out of the proceeds of any sale
Secured  Party may retain an amount equal to the principal and interest then due

pay any balance of such  proceeds to Pledgor.  In the event that the proceeds of
any sale are  insufficient  to cover the principal and interest of the Note plus
expenses  of the sale,  Pledgor  shall  remain  liable to Secured  Party for any
