payable to Greet Offices,  Inc. / American Office Centers,  L.L.C.,  30021 Tomar

whichever is greater, in the event Sublessee's check is returned for any reason,

proportionate  share of the Building's  Operating  Costs in the manner set forth
herein.  The "Building's  Operating  Costs" shall include and be computed as set

percent of the  Building  Operating  Costs  charged to  Sublessor  by the Master
Lessor.  Sublessee shall pay its proportionate share of the Building's Operating
Costs monthly,  at the same time as rent,  based upon the most recent  statement
Sublessor  has  delivered to Sublessee  which shall be delivered to Sublessee at
least every 18 months,  or at approximately  the same time Sublessor  receives a
statement from the Master Lessor, or as a provision towards said operating costs
calculated  by  Sublessor  based on  historical  data for  building  of the same
standard.  Said statement shall be based upon the statement  Sublessor  receives
from the Master Lessor and is,  therefore,  subject to change as provided in the
Master Lease.  In the event the Master Lessor  assesses a surcharge to Sublessor
based  upon a  statement  which  did  not  correctly  estimate  actual  Building
Operating  Costs,  Sublessee shall  immediately pay Sublessor its  proportionate
share of the surcharge within ten (10) days of notice to Sublessee. In the event
the Master  Lessor  issues a credit to Sublessor  due to an  overpayment  of the
Building's  Operating  Costs,  Sublessor shall apply  Sublessee's  proportionate
share of such  credit to any sums  owing from  Sublessee  to  Sublessor  and any
remaining credit to future sums due from Sublessee under this Section 4.2.

         Even if the term of this Sublease has expired and Sublessee has vacated
the Premises,  or this Sublease has terminated,  when the final determination is
made of the actual Building Operating Costs,  Sublessee shall immediately pay to
Sublessor the difference between  Sublessee's  proportionate share of the actual
Operating Costs and the amounts Sublessee has previously paid.

other sum to which  Sublessor  may  become  obligated  by reason of  Sublessee's

suffer  thereby.  If  Sublessor  so uses or applies  all or any  portion of said
deposit.  Sublessee  shall within ten (10) days after written  demand  therefor,

the full amount herein above 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 returned,  without  payment of
interest or other increment for its use to Sublessee (or at Sublessor's  option,
