06103-2604, with a copy to: R.M. Bradley & Co., Inc., 73 Tremont Street, Boston,
Massachusetts 02108".

     10. Right of First Offer. Provided that Tenant is not in default of its
         --------------------
obligations under the Lease (or no event has occurred which, but for the giving
of notice or passage of time, or both, would constitute a default), and subject
to any existing rights, including renewal rights, of other tenants in the
Building to any portion of the First Offer Space (as hereinafter defined),
Tenant shall have one right of first offer to lease up to approximately 5,216
rentable square feet of office space located on the fifth floor of the Building
contiguous to the Reduced Premises (the "First Offer Space") during the Term of
this Lease in accordance with the following terms and conditions:

         (a)  Except as otherwise provided herein, prior to Landlord entering
into a lease for all or any part of the First Offer Space with a prospective
third party tenant ("Third Party"), Landlord shall first offer in writing the
portion of the First Offer Space for lease to Tenant on the same terms and
conditions quoted to the Third Party.

                                       2

<PAGE>

         (b)  Within ten business days after Tenant receives said offer from
Landlord, Tenant shall either accept or reject such offer by written notice to
Landlord. Failure by Tenant to deliver to Landlord a written acceptance thereof
within such period shall be deemed a rejection by Tenant of such offer.

         (c)  If Tenant rejects or is deemed to have rejected said offer, then
this right of first offer shall be deemed to have terminated and shall be of no
further force or effect. Landlord may thereafter lease that portion of the First
Offer Space to any Third Party without any further obligation to Tenant
hereunder, whether or not such terms and conditions are more or less favorable
than those offered to Tenant.

         (d)  If Tenant accepts said offer in accordance with the provisions
hereof, then Landlord and Tenant shall thereupon execute an amendment to this
Lease (the "First Offer Space Amendment") adding the First Offer Space to this
Lease. If Tenant fails to execute the First Offer Space Amendment within 20 days
after Landlord furnishes same to Tenant, then the acceptance of Landlord's offer
shall be deemed to have been rejected by Tenant and thereupon the provisions of
Section 10(c) hereof shall apply.

         (e)  Prior to Landlord's execution of the First Offer Space Amendment,
Tenant shall furnish to Landlord its most current publicly available financial
statements of Tenant prepared in accordance with generally accepted accounting
principles. As a condition precedent to Landlord's adding the First Offer Space
to this Lease and Landlord executing the First Offer Space Amendment, Landlord
may evaluate and approve the financial condition of Tenant, and such approval
shall not be unreasonably withheld. If Landlord does not approve the financial
condition of Tenant, then Tenant's right of first offer shall terminate and
shall immediately be of no further force or effect, and Landlord shall be
entitled to lease the First Offer Space to any Third Party in accordance with
the provisions of this Section.

     11. Condition of Reduced Premises. Tenant's retaining possession of the
         -----------------------------
Reduced Premises as of the Extension Term Commencement Date shall be conclusive
evidence that the Reduced Premises were in good order and satisfactory condition
when Tenant retained possession. Tenant retains the Reduced Premises in an "As
Is" condition and acknowledges that no representation regarding the condition of
the Reduced Premises or the Building has been made by or on behalf of Landlord
or relied upon by Tenant. Except as otherwise provided herein, Tenant agrees
that Landlord shall not be obligated to alter, remodel, decorate, clean or
improve the Reduced Premises or the Building (or to provide Tenant with any
credit or allowance for the same). Notwithstanding the foregoing, Landlord shall
contribute up to a maximum of $167,442.00 towards the improvement of the Reduced
Premises in accordance with Exhibit C attached hereto and incorporated herein.
                            ---------

     12. Condition of Relinquished Premises. Tenant shall surrender the
         ----------------------------------
Relinquished Premises as of the date hereof in accordance with Section 10.01 of
the Lease, except as otherwise set forth herein. Tenant hereby represents and
covenants that nothing has been or shall be done or suffered whereby the Lease
or the term or estate thereby granted or the Relinquished Premises or any part
thereof, or any alterations, decorations, installation, additions or improvement
in and to the Relinquished Premises or any part thereof, have been or shall be
encumbered in any way whatsoever, and that Tenant owns and shall own Tenant's
interest in the Lease to the Relinquished Premises and has and shall have good
right to surrender the Relinquished Premises, and that no one other than Tenant
has acquired or shall acquire Tenant's interest in the Relinquished Premises, or
any part thereof, or in or to such alterations, decorations, installation,
additions and/or improvements or any part thereof. Landlord and its agents and
servants may immediately or at any time hereafter re-enter the Relinquished
Premises, or any part thereof.

     13. Brokerage Commissions. Tenant and Landlord each represent to the other
         ---------------------
party that other than R.M. Bradley & Co., Inc. ("Broker"), (i) neither party has
dealt with any real estate broker, salesperson or finder in connection with this
Amendment, (ii) no other such person initiated or participated in the
negotiation of this Amendment and (iii) no such person is entitled to any
commission in connection herewith. Tenant hereby agrees to indemnify, defend and
hold Landlord, its property manager and their respective employees harmless from
and against any and all liabilities, claims, demands, actions, damages, costs
and expenses (including attorneys' fees) arising from any claim for a fee or
commission made by any broker other than Broker claiming to have acted by or on
behalf of Tenant in connection with this Amendment.

     14. Ratification; Binding Effect. Except as hereby amended, the Lease and
         ----------------------------
all covenants, agreements, terms and conditions thereof shall continue in full
force and effect, subject to the terms and provisions thereof and hereof, and is
ratified and confirmed by the parties hereto. Lionbridge does hereby further
ratify, confirm and assume all of the obligations and liabilities of ICI as
tenant arising under, or relating to, the Lease, as amended, and any of the
other documents executed and delivered to Landlord by or on behalf of Tenant or
its successors in connection with the Lease, as amended. This Amendment (i)
shall be governed, construed, and enforced under the laws of the Commonwealth of
Massachusetts, (ii) contains the entire understanding of the parties with
respect to the provisions of the Lease amended hereby, (iii) may not be modified
except by a writing signed by both parties and (iv) and shall be binding upon
and inure to the benefit of Landlord, Tenant and their respective successors and
permitted assigns.

     15. Conflict. In the event of any conflict between the terms of the Lease
         --------
and the terms of this Amendment, the terms of this Amendment shall control.

     16. Recitals. The recitals to this Amendment and the facts set forth
         --------
therein and each writing referred to herein as being annexed hereto as an
exhibit or otherwise designated herein as an exhibit hereto are hereby
incorporated herein by reference.

     17. Counterparts. This Amendment may be executed in any number of
         ------------
counterparts, each of which shall be deemed to be an original agreement and all
of which when taken together shall be deemed to be one and the same agreement.

     IN WITNESS WHEREOF, the parties have hereunder set their hands and seal as
of the date first written above.
