         NOW THEREFORE, in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and adequacy of
which is hereby acknowledged, the parties agree as follows:

         1. Tenant agrees that the condition in Paragraph 2b of the Lease
requiring Landlord to receive an affirmative vote of the planning board with
respect to the site plan shall be deemed satisfied in full, irrespective of the
August 1, 1996 requirement contained therein, and, therefore, Tenant shall no
longer have any right to terminate the Lease or other remedy with respect to
said condition.

         2. The dates of December 31, 1996 and January 10, 1997 set forth in
paragraph 2b with respect to the right of Tenant to terminate the Lease if the
Commencement Date does not occur by a specified date, are changed to March 31,
1997 and April 10, 1997, respectively.

         3. The first sentence of paragraph 2c of the Lease is deleted and the
following inserted in its place:

                  In the event the Landlord has not completed any paving work
                  which Landlord is obligated to do pursuant to the terms of the
                  Lease (except for the "top coat" which Landlord shall not be
                  obligated to complete until June 1, 1997) by March 31, 1997,
                  Tenant may by written notice to Landlord, notify Landlord that
                  Tenant intends to complete said work.

         4. The December 31, 1996 date referred to in paragraph 2d of the Lease
with respect to completion of site work other than the aforesaid landscaping and
top coat paving, is changed to March 31, 1997.

         5. Tenant agrees that the condition contained in paragraph 2e of the
Lease with respect to roof work which Landlord was obligated to perform shall be
deemed satisfied in full, irrespective of the July 1, 1996 or the August 1, 1996
requirements contained therein, and, therefore, Tenant shall no longer have any
self help or other remedies under the Lease with respect to this condition.

         6. The December 31, 1996 date referred to in paragraph 2f of the Lease
with respect to the substantial completion of the work on the "skin" of the
building, is changed to February 28, 1997. The parties acknowledge that included
in the installation of the "skin" is any finish work integrating the "skin" and
the roof so as to form a water tight connection.

         7. Tenant agrees that the condition contained in paragraph 2g of the
Lease with respect to substantial completion of demolition of certain interior
items by Landlord shall be deemed satisfied in full, irrespective of the August
1, 1996 requirements contained therein, and, therefore, Tenant shall no longer
have any self help or other remedies under the Lease with respect to this
condition.

         8. The December 31, 1996 date contained in paragraph 16a of the Lease
with respect to the remediation of certain chemicals in the area shown on
Exhibit F by Landlord, is changed to February 28, 1997.

         9. Tenant agrees that the requirements contained in paragraph 16a of
the Lease with respect to the remediation of asbestos and "lead dust" by
Landlord, shall be deemed satisfied in full, irrespective of the June 1, 1996
requirements contained therein, and, therefore, Tenant shall no longer have any
self help or other remedies under the Lease with respect to these conditions.

         10. Tenant acknowledges that it knows of no default on the part of
either Landlord or itself under the Lease, nor does it know of any matter or
fact, which upon the giving of notice or the passage of time, or both, would
constitute a default under the Lease by either Landlord or itself.

         11. Except as modified by this Amendment, the Lease shall remain
unmodified and Tenant acknowledges that it has no existing offsets or defenses
with respect to the Lease, as amended by this Amendment or to Tenant's
obligations thereunder.

         12. The Lease, as amended by this Amendment, is and shall remain in
full force and effect and shall constitute the full and complete expression of
the lease agreement between the parties with respect to the Demised Premises.

         13. This Amendment will bind and inure to the benefit of the Landlord
and Tenant and their respective legal representatives, successors and permitted
assigns.

         The parties have executed this Amendment to the Lease on the day and
year first above written.
