(1) The effect of the provisions of this  Article  may  be  varied  by
agreement  except that no agreement can disclaim a bank's responsibility
for its own lack of good faith or failure to exercise ordinary  care  or
can  limit  the  measure  of  damages  for such lack or failure; but the
parties  may  by  agreement  determine  the  standards  by  which   such
responsibility  is  to  be measured if such standards are not manifestly
unreasonable.
  (2) Federal Reserve regulations and operating letters, clearing  house
rules, and the like, have the effect of agreements under subsection (1),
whether  or  not  specifically  assented to by all parties interested in
items handled.
  (3) Action or non-action approved  by  this  Article  or  pursuant  to
Federal   Reserve  regulations  or  operating  letters  constitutes  the
exercise of ordinary care and, in the absence of  special  instructions,
action  or  non-action consistent with clearing house rules and the like
or with a general banking usage not disapproved by this  Article,  prima
facie constitutes the exercise of ordinary care.
  (4)  The  specification  or  approval  of  certain  procedures by this
Article does not constitute disapproval of other procedures which may be
reasonable under the circumstances.
  (5) The measure of damages for failure to exercise  ordinary  care  in
handling  an  item  is the amount of the item reduced by an amount which
could not have been realized by the use  of  ordinary  care,  and  where
there  is  bad  faith it includes other damages, if any, suffered by the
party as a proximate consequence.
