       SECTION 6.04  Force Majeure  Neither party shall be liable to the other

for delay or failure to perform in whole or in part, by reason of contingencies
or events which:  (i) are beyond the reasonable control of the party whose
performance is affected, (ii) are unforeseeable, and (iii) could not have been
reasonably prevented, whether herein specifically enumerated or not (a "Force
Majeure Event").  These contingencies include, among others, act of God, act of
war, revolution, riot, acts of public enemies, fire, explosion, breakdown of
plant, strike, lockout, labor dispute, casualty or accident, earthquake, flood,
cyclone, tornado, hurricane or other windstorm, or by reason of any law, order,
proclamation, regulation, ordinance, demand, requisition or requirement or any
other act of any governmental authority, foreign or domestic, local, state or
federal (provided that the Force Majeure Event does not arise due to or is
connected in any way with a violation by party hereto of any law, order,
proclamation, regulation, ordinance, demand, requisition or requirement of any
governmental authority) except that contingencies shall not include a downturn
in Buyer's business or general economic downturn.  A party so affected by a
Force Majeure Event shall:  (i) promptly give written notice to the other party

an estimate of the expected duration of the Force Majeure Event and its probable
impact on the performance of such party's obligations  hereunder); (ii) exercise
all reasonable efforts to continue to perform its obligations hereunder; (iii)
use its commercially reasonable best efforts to overcome or mitigate the effects
of the contingency as promptly as possible and (iv) promptly give written notice
to the other party of the cessation of such contingency.  Neither party,
however, shall be required to resolve a strike, lockout or other labor problem
in a manner which it alone does not deem proper and advisable.  In no event
shall any Force Majeure Event excuse party's failure to pay when due any
monetary obligation hereunder.  In the case of any Force Majeure Event relied on
by OC, OC agrees that it shall treat Buyer no less favorably than the most
favorably treated Affiliate or customer of OC in dealing with or adjusting to
the consequences of such Force Majeure Event and in the case of any Force
Majeure Event relied on by Buyer, Buyer agrees that it shall treat OC no less
favorably than the most favorably treated Affiliate or customer of Buyer in
