be reinstated immediately.

         7. If the Lease shall be in force and effect on the  expiration  of the
Original Term, and Tenant is not in default  hereunder,  both (a) at the date of
exercise,  as  hereinafter  provided,  and (b) on the date of  expiration of the

of the Renewal Term.

         8. In the event the Tenant  exercises  its option for the Renewal Term,
then,  in such event,  Tenant shall pay to  landlord,  without  previous  demand

     A.   The first full paragraph of Paragraph 7 is deleted in its entirety.

          8.686%.

     C.   Paragraph 7(g) is deleted in its entirety.

     D.   The current rate of reimbursement to Landlord for real estate taxes is

     10. The Security  Deposit held by Landlord  pursuant to Paragraphs 1(o) and
38 shall continue to be held by Landlord; provided, however:

                  A. Landlord,  provided Tenant is not then in default under the
         terms of the Lease,  shall  credit  Tenant  with a setoff of  $3,981.18
         against its March 1, 2002  installment of Monthly Base Rental,  so that
         the actual  payment  due and payable for March 1, 2002 shall be $36.32,
         and the Security Deposit shall be reduced to $4,258.55; and

                  B. Landlord  reserves its right to inspect the Premises  after
         Tenant's  relocation  from Suite 270 to the New Premises.  In the event
         that  Suite 270 is left in any  condition  other  than  "Broom  Clean,"
         Landlord shall give notice to Tenant that such condition exists. Tenant
         shall then have a period of five (5) days from the date of such  notice
         to correct such condition  ("Correction  Period").  In the event Tenant
         has not corrected the  condition at the end of the  Correction  Period,
         Landlord may deduct from the Security Deposit, the cost and expenses of
         placing Suite 270 in Broom Clean condition.  To the extent,  if any, of
         any such deduction,  Tenant shall deposit  additional sums to reinstate
         the full Security Deposit.

     11. Notices to each party under the Lease shall be given as follows:
