                           Effective January 1, 2004 (the "Effective Date"),
                           Tenant shall vacate the Returned Space. The Premises
                           shall be reduced by eliminating from it the Returned
                           Space, and leaving unaffected the remaining portion
                           of the Premises as shown in Exhibit B attached hereto
                           (the "New Premises");

                  (B)      Article 1.1(j) and Article 4 of the Lease shall be
         amended as follows:

                           As of the Effective Date, the Base Rent for the Term
                           shall be reduced by the amount achieved by
                           multiplying the area of the Returned Space by the
                           then applicable rentable square foot Rate for the
                           Returned Space (i.e., 8,107 x $28.00 = $226,996).
                           Subject to Landlord entering a lease for the Returned
                           Space pursuant to Paragraph 3 hereinbelow, commencing
                           January 1, 2004, and month to month thereafter
                           through the earlier to occur of (i) the Lease
                           Termination Date, or (ii) the sixtieth (60) month
                           after the Rent Commencement Date, Tenant shall pay
                           without notice, demand or offset to Landlord, annual
                           Base Rent in the amount of $1,170,768.00
                           ($97,564.00/month ($116,480 - $18,916)) in advance on
                           the first day of each calendar month (subject to the
                           provisions of Sections 3 and 4 hereof). The amount of
                           such reductions and payments shall be periodically
                           recalculated as necessary in accordance with the rent
                           increase provisions set forth under section 1.1(j) of
                           the Lease;

         amended as follows:

                  As of the Effective Date, Applix shall be responsible for
         paying only its pro rata share of Additional Rent, including to the
         extent applicable Taxes, Operating Expenses and Utilities. Based on the
         reduction of the Premises by the approximately 8,107+/- rentable square
         feet contained in the Returned Space, Applix's pro rata share shall be
         83.76%.

                                     - 2 -

         (2)      Condition of Returned Space. Subject to Paragraph 3
hereinbelow, all personal property shall be removed by Applix from the Returned
Space promptly after the Effective Date, and Applix shall repair any damage
caused to the Returned Space by the removal of such possessions. All keys and/or
pass cards for the Returned Space shall be surrendered to Landlord, and the
Returned Space shall be left broom-clean and in good order, repair and
condition, reasonable wear and tear and damage by fire or casualty excepted.
Thereafter, except as required under Paragraph 3 hereinbelow, Applix shall have
no further responsibility or liability with respect to the Returned Space,
except for its continuing financial obligations as set forth in this Amendment.

         (3)      Bain Lease. The Trust agrees to immediately enter good faith
lease negotiations with Bain for the Returned Space in order to execute the Bain
Lease on terms substantially in accordance with the terms and conditions set
forth in a Letter of Intent dated December 12, 2003 by and between the Trust and
Applix, attached hereto as Exhibit C (the "LOI"). The commencement date and the
rent commencement date for the Bain Lease shall be January 1, 2004. Applix and
Bain, at their sole cost and expense, shall be responsible for any and all
necessary construction to make the Returned Space (i.e. the "Bain Premises")
comply with all local, state and federal building and health codes, including,
without limitation, the Americans with Disabilities Act of 1990, 42 USC 12111 et
seq. (the "ADA") as the same may be amended from time to time. On January 1,
2004, along with its then due installment of Base Rent, Applix shall also pay to
Landlord $9,120.00 (the "Returned Space Differential") representing the
difference between the full amount of Base Rent which would have been due by
Applix under the Lease for the Returned Space and the amount of Base Rent
payable by Bain under the Bain Lease. In the event the Trust and Bain fail to
execute the Bain Lease, for any reason or for no reason, the Landlord shall
neither be obligated to accept back the Returned Space nor restructure the Lease
with Applix.

         (4)      New Lease. Subject to the full execution of the Bain Lease,
the Trust and Applix agree to promptly begin good faith lease negotiations with
each other for the New Premises in order to execute another lease amendment for
the Restructured Lease on terms substantially in accordance with terms and
conditions set forth in the LOI. In the event the

                                     - 3 -
<PAGE>

parties fail to execute the lease amendment for the Restructured Lease by
February 1, 2004, Applix shall immediately thereafter become obligated to pay to
Landlord the Returned Space Differential monthly along with its monthly
installments of Base Rent throughout the remainder of its Term as it may be
extended from time to time.

         (5)      This Amendment shall be construed in accordance with the Laws
of the Commonwealth of Massachusetts, and may only be amended in a writing
signed by all the parties hereto. The invalidity of one or more of the
provisions contained herein as amended hereby shall not affect the remaining
provisions of the Lease, and if one or more of such provisions should be
declared invalid by final order, decree or judgment of a court of competent
jurisdiction, the Lease shall be construed as if such invalid provision or
provisions had not been included in the Lease.

         (6)      In the event that any provision of this Amendment is
inconsistent with the Lease, this Amendment shall control.

         (7)      Capitalized terms used but not defined herein shall have the
respective meanings assigned such terms in the Lease.

         (8)      Except as modified herein, all of the covenants, agreements,
terms and conditions of the Lease are hereby ratified and confirmed and shall
continue to remain unchanged and in full force and effect.

         Executed as a sealed instrument on this date.
