     do, to restrict the number of prspective bidders or purchasers and/or
     further retrict such prospective bidders or purchasers to persons who will
     represent and agree that they are purchasing for their own account, for
     investment, and not with a view to the distribution or resale of the
     Collateral and may otherwise require that such sale be conducted subject to
     restrictions as to such other matters as Pledgeholders may deem necessary
     in order that such sale may be effected in such manner as to comply with
     all applicable state and federal securities laws; upon any such sale
     Pledgeholder shall have the right to deliver, assign and transfer to the
     purchaser thereof the Collateral so sold. Each purchaser at any such sale

     whatsoever kind, including any equity or right of redemption, of Pledgor,

     within ordinary business hours and at such place or places as Pledgeholder
     may fix in the notice of such sale. At any sale the Collateral may be sold
     in whole or in part, as Pledgeholder may determine. Pledgeholder shall not

     without notice or publication, adjourn any sale or cause the same to be
     adjourned from time to time by announcement at the time and place fixed for
     the sale, and such sale may be made at any time or place to which the same
     may be so adjourned. In case of any sale of all or anypart of the
     Collateral on credit or for future delivery, the Collateral so sold may be
     retained by Pledgeholder until the selling price is paid by the purchaser
     thereof, but neither Pledgeholder nor Pledgee shall incur any liability in
     case of the failure of such purchaser to take up and pay for the Collateral
     so sold and, in case of any such failure, such Collateral may again be sold
     upon like notice. Pledgee may be the purchaser of any or all of the

disposition being considered or deemed to have been made in a commercially
reasonable manner. The rights and remedies specified in this Agreement are
cumulative and may be exercised from time to time in accordance with applicable
law and as often as Pledgeholder deems advisable. No failure to execise or delay
in the exercise of any right or remedy by Pledgeholder shall constitute a waiver
of any such right or remedy. Notwithstanding the occurrence of an Event of
Default, nothing in this Agreement shall be deemed to impose upon Pledgeholder
or Pledgee any obligation to exercise any remedy hereunder.
