                           PURCHASE AND SALE AGREEMENT

     THIS PURCHASE AND SALE AGREEMENT ("Agreement") is made as of________, 2002,
by and between 400 RIVER LIMITED PARTNERSHIP, a Massachusetts limited

     In consideration of the mutual covenants and provisions herein contained
and other good and valuable consideration, the receipt and sufficiency of which

closing date by federal wire transfer of immediately available U.S. funds to an
account of Chicago Title Insurance Company, Boston, Massachusetts (Sharon

"Closing Agent"), and hold those funds for payment to Seller on the closing.

parties in connection with this transaction who are due any commissions or
similar fees from Buyer.

FAULTS" and subject to the Mortgage and all other matters of record and
exceptions to title, as of the date of closing, without any warranty or
representation by Seller, its employees, directors, officers, agents,
consultants, representatives, partners or affiliates, subsequent owners of the
Premises, anyone acting on their behalf, or their respective successors and
assigns (including Seller, collectively, "Seller's Affiliates"), whether
relating to the Premises or this transaction or otherwise. Buyer has been a
long-term tenant in and has had the opportunity to fully investigate the
Premises, and agrees that it is not relying on any information or documents
received from or made available by or on behalf of Seller's Affiliates.
Furthermore, Buyer agrees that except for the representations and warranties of
Seller specifically set forth in this Agreement, Seller's Affiliates have not
made and Buyer is not relying on any representation, warranty, inducement or
statement (including, without limitation, those regarding the accuracy or
completeness of any information or documents furnished, or the physical or
environmental condition of the Premises, or violations of laws, or other
matters).

          (b)  As of the closing, Buyer and its employees, shareholders,
directors, officers, agents, consultants, representatives, partners, affiliates,
successors and assigns (including Buyer, collectively, "Buyer's Affiliates"),

and waive as against Seller's Affiliates all of the following (collectively, the
"Released Liabilities"): all claims, liabilities, obligations, costs, losses,
damages, penalties, judgements, actions, and causes of action of any type
(including, without limitation, attorneys' fees and costs), direct or indirect,
known or unknown, foreseen or unforeseen, including, without limitation, those
in connection with the Premises (including, without limitation, the physical and
environmental conditions thereof), the Lease, and this transaction. Buyer's
Affiliates will not commence, aid in any way, or prosecute against any of
Seller's Affiliates any claim involving or based on any of the Released
Liabilities. The provisions in this Article 9 extend to Released Liabilities
which the releasing parties may not know or suspect to exist in their favor at
the time these provisions are agreed to or at a later date, which if known to
them would materially affect their willingness to agree. The provisions of this
Article 9 will survive the closing or termination of this Agreement.

     10.  Default. A party will be in default hereunder if it materially
breaches its obligations hereunder and fails to cure within two (2) business
days after written notice from the other party, or if any of its representations
or warranties in this Agreement are materially untrue or incorrect when made or
as of the closing. Seller will indemnify, defend and hold harmless Buyer's
Affiliates from all claims, liabilities, obligations, costs, losses, damages,
penalties, judgements, actions, and causes of action of any type (including,
without limitation, attorneys' fees and costs) in connection with Seller's
breach of its representations, warranties and indemnities in this Agreement and
its obligations in this Agreement, if any, that survive the closing or the
termination of this Agreement. Buyer will indemnify, defend and hold harmless
Seller's Affiliates from all claims, liabilities, obligations, costs, losses,
damages, penalties, judgements, actions, and causes of action of any type
(including, without limitation, attorneys' fees and costs) in connection with
Buyer's breach of its representations, warranties and indemnities in this
Agreement, its obligations in the Lease that survive the expiration or
termination of the Lease, and its obligations in this Agreement, if any, that
survive the closing or the termination of this Agreement.

     11.  Notices. All notices under this Agreement will be in writing and will
be deemed to have been properly given if and when delivered in person, or on
delivery or attempted delivery (if delivery is refused) by a
nationally-recognized overnight courier, addressed to each party at the
addresses set forth below. Either party may change its addresses by written
notice as set forth above.

                                    Andover, Massachusetts 01810

         12.      Miscellaneous Provisions.

                  (a) This Agreement is an integrated agreement and, except for
the agreements contemplated herein and the escrow instructions to accomplish
this agreement (including the Undertakings Agreement), it contains the entire
understanding between the parties with respect to the transaction contemplated
herein, and all prior agreements, understandings, representations and
statements, oral or written are merged into this Agreement. The delivery of the
deed by Seller will be deemed the full performance and discharge of every
obligation on the part of Seller to be performed hereunder, except for any
obligations of Seller which are expressly provided herein to survive the
closing. No provision of this Agreement may be waived except by an instrument
signed by the party against whom the enforcement of such waiver is sought. All
modifications (including any extensions) of this Agreement will be effective
only if signed by Seller and Buyer.

                  (b) This Agreement will be governed by, and construed in
accordance with, the local, internal laws of the Commonwealth of Massachusetts
applicable to agreements to be wholly performed therein, without regard to
conflicts of laws.

                  (c) This Agreement will be binding on and will inure to the
benefit of the parties hereto and their respective successors and assigns,
provided, however, that Buyer will not have the right or power to assign or
transfer this Agreement. This Agreement and its terms are for the sole benefit
of the parties hereto (including, without limitation, the released Seller's
Affiliates) and their permitted successors and assigns, if any, and no other
person or entity will have any right of action hereon or right to claim any
right or benefit from this Agreement or its terms or be deemed a third party
beneficiary hereunder. Except for the representations and warranties
specifically set forth in this Agreement, there are no representations and
warranties, express or implied, that are being made or relied on by the parties
hereto. All representations, warranties and indemnities hereunder will survive
the closing of this Agreement.

                  (d) Notwithstanding anything to the contrary in the Lease or
elsewhere, and without diminishing any amounts payable for the Purchase Price,
as of and after the closing Buyer, as Tenant under the Lease and in all other
capacities (and this Subsection 12(d) will be deemed to be an amendment of the
Lease if and to the extent necessary), and on its own behalf and on behalf of
Buyer's Affiliates, irrevocably will be deemed to have released and waived all
of its rights and any rights of Buyer's Affiliates in connection with the $2.5
Million "Additional Security" (as defined in the Lease), which may continue to
be used as collateral for the Loan and/or for Landlord's or the Lender's
conversion of all or part of the data center portion of the Building to office
space (because Buyer's use is so specialized) and/or for other Landlord or
Lender tenant improvements or otherwise. Buyer will promptly execute and deliver
(or cause to be executed and delivered) such other documents as Landlord or the
Lender reasonably require in order to evidence the terms of this Subsection
12(d). Buyer's release, waiver and covenants in this Section 12(d) will survive
the closing, and collectively are referred to as the "Additional Collateral
Obligations."

                  (e) The section titles or captions in this Agreement are for
convenience only and will not be deemed to be part of this Agreement for
purposes of interpreting, construing or enforcing any of the provisions of this
Agreement. All pronouns and any variations of pronouns will be deemed to refer
to the masculine, feminine, or neuter, singular or plural, as the identity of
the parties may require. Whenever the terms referred to herein are singular, the

                                        4

<PAGE>

same will be deemed to mean the plural, as the context indicates, and vice
versa. This Agreement will not be construed as if it had been prepared only by
Buyer or Seller but rather as if both Buyer and Seller had prepared and
negotiated it. This Agreement is severable, and if any term, covenant,
condition, or provision of this Agreement or the application thereof to any
person or circumstance will, at any time or to any extent, be invalid or
unenforceable, the remainder of this Agreement, or the application of such term
or provision to persons or circumstances other than those to which it is held
invalid or unenforceable, will not be affected thereby, and each term or
provision of this Agreement will be valid and will be enforced to the fullest
extent permitted by law.

                  (f) If the time period by which any right, option or election
provided under this Agreement must be exercised, or by which any act required
hereunder must be performed, or by which the closing must be held, expires on a
day which is a Saturday, Sunday, or official federal or Commonwealth of
Massachusetts holiday, then such time period will be automatically extended
through the close of business on the next business day.

                  (g) No Seller's Affiliate (other than Seller itself) will have
any personal liability hereunder, nor will any of them be named personally in
any suit, claim, action or proceeding concerning any matters hereunder nor will
any of their assets be attached, liened or levied or in any other way become
liable for any of the obligations of Seller hereunder, nor will either party
attempt to "pierce the corporate veil" of any of Seller's Affiliates or any of
Buyer's Affiliates.

                  (h) This agreement may be executed in two (2) or more
counterparts, each of which will be deemed to be an original, but all of which
taken together will constitute one and the same Agreement. All of the Exhibits
referenced in this Agreement will be deemed incorporated into this Agreement.

                  (i) If there is any dispute relating to this Agreement or a
breach hereunder, the prevailing party will be entitled to payment for all costs
and attorneys' fees (both trial and appellate) incurred in connection therewith.
All suits, actions, claims and proceedings will be filed, commenced and
prosecuted solely in the state or federal courts in Boston, Massachusetts, which
will have sole and exclusive jurisdiction and venue. The provisions in this
Subsection (i) will survive the closing or termination of this Agreement.

         In witness whereof, intending to be legally bound, the parties have
executed this Agreement under seal as of the date first set forth above.
