PARAGRAPH 12 (e) BELOW, unless sooner terminated pursuant to any provision
hereof.

    3.2  DELAY IN COMMENCEMENT.  Notwithstanding said commencement date, if for
any reason Sublessor cannot deliver possession of the Premises to Sublessee on
said date, Sublessor shall not be subject to any liability therefore nor shall
such failure affect the validity of this Lease or the obligations of Sublessee
hereunder or extend the term hereof, but in such case Sublessee shall not be
obligated to pay rent until possession of the Premises is tendered to
Sublessee, provided, however, that if Sublessor shall not have delivered
possession of the Premises within sixty (60) days from said commencement date,
Sublessee may, at Sublessee's option, by notice in writing to Sublessor within
ten (10) days thereafter, cancel this Sublease, in which event the parties
shall be discharged from all obligations thereunder.  If Sublessee occupies the
Premises prior to said commencement date, such occupancy shall be subject to
all provisions hereof, such occupancy shall not advance the termination date
and Sublessee shall pay rent for such period at the initial monthly rates set

Sublessee's default or to compensate Sublessor for any loss or damage which
Sublessor may suffer thereby.  If Sublessor so uses or applies all or any
portion of said deposit, Sublessee shall within ten (10) days after written
demand therefore deposit cash with Sublessor in an amount sufficient to restore
said deposit to the full amount hereinabove stated and Sublessee's failure to
do so shall be a material breach of this Sublease.  Sublessor shall not be
required to keep said deposit separate from its general accounts.  If
Sublessee performs all of Sublessee's obligations hereunder, said deposit, or
so much thereof as has not theretofore been applied by Sublessor, shall be
