      period set forth in such provisions (if any), all amounts due to the Lenders

      events, the Lender shall have, in addition to any remedies provided herein
      or by

      Grantor at least seven (7) days before the time of the intended sale or
      disposition. Expenses of retaking, holding, preparing for disposition, disposing
      or the like shall include the Lender’s reasonable attorneys’ fees and legal
      expenses, incurred or expended by the Lender to enforce any payment due it
      under
      this Agreement either as against the Grantor, or in the prosecution or defense
      of any action, or concerning any matter growing out of or connection with the
      subject matter of this Agreement and the Collateral pledged hereunder. The

      that
      such appointment shall only be effective after and during the continuation
      of an
      Event of Acceleration . The
      Grantor hereby ratifies all that said attorney shall lawfully do or cause to
      be
      done by virtue hereof. This power of attorney is coupled with an interest,
      and
      is irrevocable. The
      Lender shall notify the Grantor in
      writing of any action taken by it in accordance with this Section
      11.

      such right or power, nor will the Lender’s action or inaction impair any such
      right or power. The Lender’s rights and remedies hereunder are cumulative and
      not exclusive of any other rights or remedies which the Lender may have under
      other agreements, at law or in equity.





**15.** **Illegality** **.** If any
      provision contained in this Agreement should be invalid, illegal or
      unenforceable in any respect, it shall not affect or impair the validity,
      legality and enforceability of the remaining provisions of this
      Agreement.





**16.** **Changes
      in Writing** **.** No
      modification, amendment or waiver of, or consent to any departure by the Grantor

      signed by the Lender, and then such waiver or consent shall be effective only
      in
      the specific instance and for the purpose for which given. No notice to or
      demand on the Grantor will entitle the Grantor to any other or further notice
      or
      demand in the same, similar or other circumstance.





**17.** **Entire
      Agreement** **.** This
      Agreement (including the documents and instruments referred to herein) and
