                              ---------------------

contained herein and the benefits to be derived therefrom.

                                   WITNESSETH:

         WHEREAS, Landlord and Tenant entered into a certain Lease (the "Lease")
dated February 8, 2000, pursuant to which Landlord leased to Tenant certain
premises containing approximately 7,090 square feet of space on the second (2nd)
floor of a certain building located at 25 Corporate Drive, 500 Burlington
Centre, Burlington, Massachusetts; and

         WHEREAS, Tenant desires to terminate the term of the Lease prior to the
scheduled expiration date thereof; and

         WHEREAS, Landlord is willing to terminate the term of the Lease prior
to the scheduled expiration date thereof, subject to the terms and conditions
hereinafter set forth;

         NOW THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Landlord and the Tenant agree
as follows:

         1.       Defined Terms.
                  -------------

         Any capitalized terms used but not defined in this Agreement shall have

         2.       Termination of Term of Lease.
                  ----------------------------

         Subject to Tenant's performance of its Surrender Obligations and
payment in full in good funds of the Remaining Rent Payments and the Termination
Fee (as such terms are hereinafter defined), the Lease Term shall be terminated
effective as of the date of this Agreement (hereinafter, the "Effective

         3.       Remaining Rent Payments.
                  -----------------------

         Base Rent and other charges due under the Lease shall be due and
payable by the Tenant through, and shall be apportioned as of, the Effective
Termination Date (collectively, the "Remaining Rent Payments").

         4.       Termination Fee.
                  ---------------

         In consideration of the early termination of the Lease Term and in
addition to the Remaining Rent Payments, Tenant shall pay to Landlord a fee (the
"Termination Fee") equal to Sixty-Nine Thousand One Hundred Ninety Eight and
40/100 Dollars ($69,198.40). The Termination Fee shall be due and payable in
full upon the execution and delivery of this Agreement by the Tenant to the
Landlord.

         5.       Surrender Obligations.
                  ---------------------

         On or prior to the Effective Termination Date, the Tenant shall
surrender the Premises to the Landlord vacant and in broom clean condition and
otherwise in compliance with the terms and conditions of the Lease
(collectively, the "Surrender Obligations"). Without limiting such Surrender
Obligations, on or prior to the Effective Termination Date the Tenant shall
remove all of Tenant's personal property and shall repair any damage to the
Premises caused by such removal, provided that Tenant may leave at the Premises
those pieces of its furniture which Tenant has conveyed to Performix
Technologies, Inc. ("Performix") and which Performix has accepted pursuant to a
separate written agreement between Tenant and Performix.

         6.       Operating Expenses and Taxes.
                  ----------------------------

         Tenant acknowledges that Tenant's payments on account of Operating
Expenses and Property Taxes for the Year in which the Effective Termination Date
occurs (and possibly, for the immediately preceding Year) may be based upon
estimated amounts of Operating Expenses and Property Taxes, respectively. At the
time that the actual amount of Operating Expenses and Property Taxes,
respectively, for such Year(s) are determined, either Tenant shall promptly pay
any underpayment to Landlord or Landlord shall promptly refund any overpayment
to Tenant.

         7        Release.
                  -------

         Tenant, for itself, its legal successors and assigns, its agents,
servants and employees, and each of them, does hereby release and forever
discharge the Landlord, Trammell Crow Company, the Property Manager, and their
respective legal successors and assigns, shareholders, partners, agents,
servants and employees (all of the foregoing, collectively, the "Landlord
Parties"), of and from any and all claims, demands, damages, debts, liabilities,
actions, and causes of action of every kind and nature whatsoever, whether now
known or unknown, which Tenant ever had, now has or hereafter may have against

upon, or relating to, any act, omission, event, matter or thing occurring at any
time up to the date of this Agreement; provided, however, that nothing in this
Agreement is intended to release Landlord from its obligations to be performed
hereafter under the Lease prior to the Effective Termination Date.

         8.       Lease Still in Effect.
                  ---------------------

         Except as modified hereby, all terms and conditions of the Lease shall
remain in full force and effect until the Effective Termination Date, after

each other under the Lease, except for any provisions which by their terms
