    (1)   the Purchaser may, by notice to the Company, declare the entire unpaid
principal amount of the Notes, all interest accrued and unpaid thereon and all
other amounts payable under this Agreement to be forthwith due and payable,

automatically become due and payable), without presentment, demand, protest or

Company hereby agrees that the holders of the Warrants or the Warrant Shares
would have no adequate remedy at law, for monetary compensation or otherwise,
for the damages that would be suffered if the company were to fail to comply
with its obligations under Articles VII and VIII, and that the Company therefore
agrees that the holders of the Warrants and the Warrant Shares shall be entitled
to obtain specific performance of the Company's obligations under Articles VII
and VIII of this Agreement.

    8.02  Annulment of Defaults. Section 8.01 is subject to the condition that,
          ---------------------
if at any time after the principal amount of any of the Notes shall have become
due and payable, and before any judgment or decree for the payment of the moneys
so due, or any portion thereof, shall have been entered, then and in every such
case the holders of at least a majority of the principal amount of all Notes
then outstanding may, by written instrument filed with the Company, rescind and
annul such declaration and its consequences; but no such rescission or annulment
shall extend to or affect any subsequent default or Event of Default or impair
any right consequent thereon.

                   12% PROMISSORY NOTE DUE OCTOBER 31, 2001

$5,000,000                                    June 29, 2001

     FOR VALUE RECEIVED, Lionbridge Technologies, Inc., a Delaware corporation
(the "Company"), hereby promises to pay to Capital Resource Partners IV, L.P., a
Delaware limited partnership, or assigns (hereinafter referred to as the
"Payee"), on October 31, 2001, the principal sum of FIVE MILLION DOLLARS
($5,000,000) or such part thereof as then remains unpaid, and to pay interest
from the date hereof on the whole amount of said principal sum and accrued
interest remaining from time to time unpaid at the rate of twelve percent (12%)
per annum, such interest to be payable quarterly in arrears on the last Business
Day (as defined in the Purchase Agreement referred to below) of March, June,
September and December, beginning September 30, 2001, until this Note is paid in
full. Principal and interest shall be payable in lawful money of the United
States of America, in immediately available funds, by wire transfer of funds to
the account or accounts designated in writing by the Payee or in such other
manner as the Payee may designate from time to time in writing to the Company.
Interest shall be computed on the basis of a 360-day year for the actual number
of days elapsed. Nothing in this Note shall require the Company to pay interest
at a rate in excess of the maximum rate permitted by applicable law. Any
interest payable hereunder or under any other instrument relating to the
indebtedness evidenced hereby that is in excess of the maximum rate permitted by
applicable law shall, in the event of acceleration of maturity, late payment,
prepayment, or otherwise, be applied to a reduction of the unrepaid indebtedness
evidenced hereby and not to the payment of interest, or if such excessive
interest exceeds the unpaid balance of such unrepaid indebtedness, such excess
shall be refunded to the Company. To the extent not prohibited by applicable
law, determination of the maximum rate permitted by applicable law shall at all
times be made by amortizing, prorating, allocating and spreading in equal parts
during the full term of the indebtedness evidenced hereby, all interest at an
time contracted for, charged or received from the Company in connection with the
indebtedness evidenced hereby, so that the actual rate of interest on account of
such indebtedness is uniform throughout the term thereof.

     This Note is issued pursuant to and is entitled to the benefits of a
certain Note and Warrant Purchase Agreement, dated as of the date hereof, by and
between the Company and the Payee (as the same may be amended, modified,
supplemented or restated from time to time, referred to herein as the "Purchase
Agreement"), and each holder of this Note, by its acceptance hereof, agrees to
be bound by the provisions of the Purchase Agreement.  The Company and the Payee
acknowledge and agree that in case of an Event of Default, as defined in the
Purchase Agreement, the entire unpaid principal of this Note and all interest
accrued and unpaid thereon may automatically become or may be declared due and
payable in the manner and with the effect provided in the Purchase Agreement.
If an Event of Default as defined in the Purchase Agreement has occurred and is
continuing, from and after the date thirty (30) days after the date such Event
of Default occurred any outstanding unpaid principal hereof and any accrued but
unpaid interest from time to time due thereon shall bear interest, payable on
demand, at the rate of fifteen percent (15%) per annum, or such lower rate as
then may be the maximum rate permitted by applicable law, provided, however,
                                                          --------  -------
that upon the cessation or cure of such Event of Default, if no other Event of
Default is then continuing, this Note shall again bear interest at the rate
first set forth above.

     This Note is convertible into other securities of the Company as set forth
in the Purchase Agreement.
